Resumo: O objetivo desta pesquisa foi determinar os níveis de atenuação de Dispositivos de Proteção Auditivos (DPAs), usando um teste chamado Resposta Auditiva de Estado Estável (RAEE). O teste RAEE é um exame eletrofisiológico que usa elétrodos para captar a atividade elétrica do tronco encefálico, sem depender da resposta do indivíduo, eliminando a subjetividade, assim como aspectos ligados à atenção, tempo de resposta, níveis de audição, etc. Neste método foram avaliados dez indivíduos, por meio da RAEE, estimulando-se o sistema de audição, primeiro sem protetor e, subsequentemente, com dois tipos de protetores auditivos, a saber um de inserção intra-auricular outro circunauricular de uso comum no mercado. Os resultados evidenciaram valores inferiores àqueles expressos no Certificado de Aprovação: para o plug, uma diferença de 10,3 dB, e para a concha, 4,3 dB. Na repetição dos testes, encontrou-se uma boa repetitividade, com diferença entre zero e 5 dB para 75% das frequências testadas.
Abstract: The purpose of this research was to determine the levels of attenuation of Hearing Protection Devices (HPDs) using a test called Auditory Steady-State Response (ASSR). The ASSR test is an electrophysiological examination that uses electrodes to capture the electrical activity of the auditory nerve and the brainstem without depending on the individual's response, thus eliminating the subjectivity of personal factors such as attention, response time, hearing ability, etc. This paper presents the results of a ten test which evaluated the hearing threshold of individuals, by first stimulating the hearing system without a protector and subsequently with a hearing protector. The results of this study were lower than those expressed in the Certificate of Approval: to plug a gap of 10.3 dB and dB the ear mufflers. The repetition of tests found a good repeatability with a difference between zero and 5 dB for 75% of the frequencies tested.

Resumo: A presente Dissertação de Mestrado se insere na Linha de Pesquisa "Processos Formativos, Diferença e Valores", que tem se preocupado em realizar estudos interdisciplinares sobre processos formativos históricos, culturais, sócio-educativos e psicológicos implicados na produção de práticas educativas, e de forma particular, em uma vertente comprometida com aspectos da sexualidade infanto-juvenil, desenvolvimento humano e situação de risco pessoal e social, inclusão/exclusão social e escolar nos processos educativos ligada aos estudos realizados no LDH - Laboratório de Desenvolvimento Humano da FCT/UNESP. A pesquisa tem como objeto de estudo as percepções de adolescentes estudantes de escolas públicas de Presidente Prudente, com idade entre 14 e 18 anos, acerca de escola em que estudam. Considerando os poucos estudos que relacionem a construção de mecanismos de resiliência em adolescentes com processos escolares, acredita-se que olhar para a perspectiva do próprio sujeito em questão se faz necessário para compreender a forma como este sujeito tem atribuído sentidos a estes processos e os impactos causados por eles em sua constituição subjetiva. Estudos como este podem contribuir para a reflexão sobre a forma como a escola tem agido na vida dos adolescentes, especialmente aqueles que vivem expostos a situações adversas, e pensar nesta instituição enquanto um espaço propício para o desenvolvimento de processos de resiliência nestes indivíduos. Foram enfatizados os aspectos relacionados às experiências e relacionamentos vivenciados entre os adolescentes e os profissionais da escola, bem como entre eles e seus pares; suas percepções e sentimentos com relação ao seu rendimento escolar; as expectativas depositadas na escola e nos estudos relativamente aos seus projetos de vida e suas percepções acerca do ambiente escolar...

Abstract: This research is tied to the research line "Formative processes, Difference and Values", that has as main concern the development of interdisciplinary knowledge about teacher's practices and representations, associated with historical, cultural, social and psychological aspects involved in the production of educational practices, and more particularly, with a perspective that values aspects of infant-juvenile sexuality, human development, personal and social risk condition, social and educational inclusion/exclusion and their impacts in the educational process, linked with the studies carried out by the research group "Laboratory of human development" - LDH, at FCT/UNESP. The research has as main purpose to study the perceptions of teenagers, students of public schools in Presidente Prudente, aged between 14 to 18 years old, about the role of the school in their lives. Taking into account the few studies that analyses the construction of resilience in an articulated way with educational process, it is believed that the analysis of the own perspective of the students is needed, if we aim to understand the meanings attributed to the educational process and its impacts into their subjectivity. Our study is helpful since it contributes for the reflection about the ways the school has affected youth's lives, especially of those exposed to adversities and thinking about this institution as an opportune place for the development of resilience among this youth. It was emphasized aspects related to the experiences and relationships established between the teenagers and school professionals and also among peers; teenager's perceptions and feelings about their educational performance; the role of the school in their life projects and their perceptions about the school settings...

Resumo: A preocupação com a radiação ultra-violeta (UV) do espectro eletromagnético que atinge a superfície terrestre, devido ao aumento do índice de câncer de pele, tem incentivado a pesquisa de produtos para a proteção da pele. Este trabalho tem como objetivo a obtenção e estudo do filtro inorgânico ZnO:Ti4+ com 1, 5, 10, 20, 40, 50% em mol do dopante e a associação dos filtros dopados obtidos com o filtro orgânico 1-(4-terc-butilfenil)-3-(4- metoxifenil)propano-1,3-diona ou butil metoxi dibenzoil metano (bmdm), comercialmente denominado Eusolex 9020. Os filtros dopados foram obtidos pelo método sol-gel, com razão de hidrólise de 0,1 e de 0,01. As amostras foram caracterizadas por espectroscopia de absorção através de medidas de refletância difusa (RD), espectroscopia na região do infravermelho (IV), espectroscopia na região do ultravioleta - visível (UV-Vís), difratometria de raios X (DRX), colorimetria, medidas de potencial zeta, razão UVA/UVB e comprimento de onda crítico foram calculados para conhecer o desempenho dos filtros na região do UVA. Os resultados de DRX indicam a formação da fase ZnO wurtzita para dopagens de até 10%. Acima dessa porcentagem de "dopante", observa-se a formação de fases de titanatos de zinco (Zn2TiO4 e ZnTiO3). Os espectros no IV apresentam bandas referentes à ligação metaloxigênio deslocadas para maiores números de onda com o aumento da quantidade de dopante, devido ao efeito da força de ligação e do tamanho do íon de titânio em relação ao de zinco nas interações metal-oxigênio. Os espectros de RD apresentam deslocamento das bandas para a região do visível. Os filtros dopados obtidos foram, então, associados com o filtro orgânico bmdm. Os filtros associados foram caracterizados pelas mesmas técnicas acima descritas. Nos espectros IV dos filtros... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The concern with UV radiation of the electromagnetic spectrum that reaches the earth's surface has encouraged the research of products for skin protection due to increased rates of skin cancer. This study aims to obtain and study the inorganic filter ZnO:Ti4+ with 1, 5, 10, 20, 40, 50 at% of doping and the association with doped filters developed through organic filter 1 - (4-tert- butyl phenyl) -3 - (4-methoxyphenyl) propane-1 ,3-dione or butyl methoxy dibenzoyl methane (bmdm), trade name Eusolex 9020®. Doped filters were obtained by the sol-gel method, with hydrolysis ratio of 0.1 and 0.01. The samples were characterized by absorption spectroscopy using diffuse reflectance (DR), infrared (IR) spectroscopy, ultraviolet - visible (UV-Vis), X-ray diffraction (XRD), colorimetric and zeta potential measurements. UVA/UVB ratio and critical wavelength were calculated to know the filter's performance in the UVA region. XRD results indicate the ZnO wurtzite phase formation step for doping levels up to 10%. Above this percentage of doping, phases of zinc titanates (Zn2TiO4 and ZnTiO3) we observed. The IR spectra show bands of the metal-oxygen shifted to higher wave numbers and an increasing amount of dopant due to the bond strength and size effects of the titanium ion compared to zinc ion in metaloxygen interactions. The RD spectra show shifts of bands for the visible region. Doped filters were then associated with the bmdm organic filter. The associated filters were characterized by the same techniques just described above. In the IR spectra of the associated filters, there is also the band on the metal-oxygen, splitting and shifting of the band related to the carbonyl group when compared with the free bmdm, that indicates an association between the filters. The absorption bands of doped filters do not cover... (Complete abstract click electronic access below)

Resumo: O presente estudo investigou os fatores de risco e os mecanismos de proteção na história de desenvolvimento de 16 adolescentes com diagnósticos de transtornos mentais, em atendimento médico-psicológico em instituição de saúde mental. Foram realizados 16 estudos de caso por meio de entrevistas semi-estruturadas, realizando-se o levantamento de dados demográficos das adolescentes e de seus pais, dados de diagnóstico , do tratamento que realizam e a identificação dos fatores de risco e mecanismos de proteção, além da classificação de sua capacidade adaptativa atual, de acordo com a Escala Diagnóstica Adaptativa Operacionalizada (EDAO). Os resultados permitiram a identificação dos fatores de risco e dos mecanismos de proteção, os quais mostraram-se consistentes com os encontrados na literatura. As condições gerais das adolescentes mostraram-se mais positivas do que negativas, bem como a classificação adaptativa que obtiveram, ao contrário do que poderia ser esperado, em função de seus diagnósticos de transtornos mentais. Os resultados indicam a importância da família e das relações escolares como promotores do desenvolvimento de mecanismos de proteção, devendo-se também considerar os aspectos individuais como facilitadores ou não de desenvolvimentos menos suscetíveis aos riscos inevitáveis. As classificações adaptativas obtidas pelas entrevistadas e a análise dos fatores de risco e mecanismos de proteção identificados em sua história de desenvolvimento, são concordantes com o apontado na literatura, indicando a plasticidade e flexibilidade deste processo, bem como as dificuldades de se considerar os transtornos mentais na adolescência, em que o desenvolvimento continua ocorrendo e promovendo mudanças quantitativas e qualitativas significativas.

Abstract: The present study investigated the risk factors and the mechanisms of protection in the history of development of sixteen teenagers with diagnoses of mental disrupitions, in medical-psychological attendance in mental health institution. Sixteen case studies were carried out through semi-structured interviews, realizing the survey of demographic data of the teenagers and their parents, dianosis data and the treatment that theycarry out and the identification of the risk factors and mechanisms of protection, besides the classification of its current adaptative capacity, according to the Operationalized Adaptative Diagnosis Scale (OADS). The results allowed the identification of the risk factors and the mechanisms of protection, which seemed themselves consistent with the others found in the literature. The general conditions of the teenagers showed themselves more positive than negative, as well as the adaptative classification that they obtained, unlike what could be expected, according their diagnoses of mental desrupitions. The results indicate the importance of the family and the school relations as development promoters of mechanisms of protection, it also needs to be considered the individual aspects as easy ways or not of development less touchy to the inevitable risks. The adaptative classifications obtained by the interviewed teenagers and the analysis of risk factors and mechanisms of protection identified in their histories of development are in agreement with the pointed out in the literature, indicating the plasticity and flexibility of this process, as well as the difficulties of considering the mental disruptions in the teenage, which the development...

Resumo: A reciclagem de resíduos sólidos no Brasil ocupa atualmente uma posição de destaque mesmo se comparada com países mais desenvolvidos. As empresas de nosso país, de qualquer dimensão ou tipo de atividade, podem potencializar essa performance se valendo de políticas que priorizem a transformação de algo sem valor econômico e sem utilidade, em matérias - primas secundárias. Sob a ótica da abordagem metodológica, este trabalho teve por objetivo geral identificar, analisar, propor e avaliar as medidas adotadas pela empresa estudada, na coleta de resíduos gerados em suas atividades que podem ser submetidos à reciclagem ao invés de serem enviados para aterros. Foram identificadas as práticas de coleta adotadas para os resíduos, analisando a aderência das mesmas aos princípios que preconizam os objetivos da reciclagem. Como decorrência dos resultados dessa análise foi desenvolvida e implantada uma metodologia de coleta seletiva para os resíduos em estudo. Nesse desenvolvimento foram contemplados aspectos como: pontos de geração de resíduos, adequação dos tipos de acondicionadores, logística interna, instruções operacionais, necessidade de registro de dados e treinamento dos funcionários e gestores. Foram escolhidos para estudo na implantação da metodologia os seguintes resíduos: alumínio, papel e papelão, plástico em geral, fita poliéster para embalagem, fita de aço para embalagem, aço inox, metal ferroso e metal não ferroso. Avaliações posteriores foram realizadas com a finalidade de medir a eficácia das novas práticas adotadas bem como para apurar os volumes destinados à reciclagem decorrentes da seletividade da coleta e da interrupção do envio de resíduos recicláveis para aterros. Essas avaliações apresentaram resultados satisfatórios quando comparadas com o estado da arte caracterizado no inicio do trabalho... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Solid waste recycling in Brazil has a prominent position even when compared with more developed countries. The enterprises in our country, of any dimension or type of activity, can maximize this performance by adopting policies that prioritize the transformation of something worthless and useless into secondary raw material. From the point of view of the methodological approach, this work aims to identify, analyze, propose and evaluate the measures adopted by the studied company in the collection of determined waste produced by its activities which can be recycled, instead of being sent to landfills. We have identified the practices applied to the waste, analyzing its adherence to the principles which advocate the objectives of recycling. As a consequence of the results of this analysis, we have developed and implemented a methodology for the selective collection of the waste examined. In this development we have contemplated some features, such as points of waste production, adequacy of the kinds of packing, intern logistics, operational instructions, need of data record and employees and managers training. The following kinds of waste have been chosen to be studied in the implementation of the methodology: aluminum, wavy packing paper (cardboard), plastic in general, polyester tape for packing, steel tape for packing, inox steel, ferrous and non-ferrous metals.Later evaluations have been made aiming to measure the efficacy of the new practices adopted as well as to check the volumes sent to recycling as the result of the selectiveness of the collection and of the interruption of the sending of recyclable waste to landfills.These evaluations presented satisfactory results when compared with the state of the art in the beginning of the work, before the implementation of the selective waste collection procedures. The results show that the excellence level of the work process ... (Complete abstract click electronic access below)

Resumo: O desenvolvimento de produtos de uso pessoal que seguem o design antropomórfico nem sempre podem ser planejados em detalhes mínimos para adaptação em sujeitos que representam as extremidades estatísticas da antropometria. Atento a esse obstáculo, o projeto do produto necessita de recursos que permitam contornar essa limitação. O uso de materiais que possuem capacidade de deformação elástica / moldabilidade se torna viável no sentido de adaptar o produto ao usuário, de forma a otimizar seu desempenho, obtendo maiores índices de segurança, conforto e preferência subjetiva sem modificar sua estrutura básica em função de detalhes antropométricos. A aplicação de forma planejada em locais estratégicos onde exista maior contato com o corpo, sob pressão via peso ou força aplicada faz com que o material se molde aos contornos locais do corpo, proporcionando conforto, firmeza e segurança. São elementos primordiais para a ideal funcionalidade de um produto e que agregam valores preferenciais no poder de decisão do usuário. Dessa forma, é compilado o conceito dos Materiais Miméticos, cujo foco do presente estudo é a análise de preferência subjetiva de sujeitos por equipamentos de proteção individuais que possuem esses materiais moldáveis ao corpo como parte fundamental de sua estrutura; a constatação que a preferência está ligada às sensações produzidas através do material; os fatores decisivos para a escolha definitiva do usuário; análise de interface; e elementos secundários de design para contribuição referencial...

Abstract: Development of products for personal use that follows the anthropomorphic design can not ordinarily be planned with meticulous details for the adjustment to subjects who represent the statistical extremes of anthropometry. Considering this obstacle, the productþs project demands resources that make it possible to hurdle this limitation. The use of material with flexible deforming capacity / capacity of shaping becomes something viable in a sense of adjusting product to user in order to enhance their performance, obtaining higher rates of safety, comfort and personal preference without modifying the basic structure in assignation of anthropometric details. The previously planned application in strategic areas where there is a greater contact with the body, under pressure by weight or employed strength, makes the material adapt to local contours of the body providing comfort, firmness and security. These are primal elements for the ideal functioning of a product and they aggregate preferential values to the userþs power of choice. This way, it is formulated the concept of Mimetic Materials, related to the aim of this study which are the analysis of subjectsþ personal preference for personal protection equipments that have this kind of material adaptable to the body as a fundamental part of their structure; the verification that preference is related to sensations produced by the material; decisive factors for userþs final choice; analysis of the interface; and secondary elements of design for referential contribuition...

Resumo: A proteção de superfícies metálicas é um assunto de grande interesse científico e econômico. As vultosas quantias empregadas regularmente em manutenção e conservação motivam estudos para a obtenção de materiais com maior durabilidade e manutenção de seu aspecto estético. Neste trabalho é proposto o desenvolvimento de um dispositivo de geração de plasma via eletrólise e a investigação de sua aplicabilidade no aumento da resistência a corrosão da liga de alumínio 2024. A alteração da resistência à corrosão conferida pelo filme ao substrato foi investigada através de ensaios de névoa salina e de impedâncias eletroquímica e de polarização. A composição e a estrutura química dos revestimentos foram analisadas por espectroscopia de absorção no infravermelho. Perfilometria e o método de correntes parasitas foram empregados na determinação da espessura das camadas depositadas, enquanto alterações da molhabilidade das superfícies foram avaliadas por medidas de ângulo de contato. Os resultadeos mostram que, sob determinadas condições, o tratamento aumentou em cerca de 145 vezes, em comparação com substratos sem tratamento, a resistência das amostras a exposição à névoa salina.
Abstract: The protection of metallic surfaces is a subject of great scientific and economical interests. The huge amounts of money regularly employed in maintenance and conservation motivate investigations on the production of materials with larger durability, preserving the esthetic aspect. In this work, it is proposed the development of an electrolytic plasma device and the investigation of its applicability on the improvement of the resistance to corrosion of 2024 aluminum alloy coupons. Modifications in corrosion resistance conferred by the films to the substrates have been evaluated through salt spray tests and electrochemical and polarization impedances. Fourier infrared absorption spectroscopy has been employed to assess composition and chemical structure of the coatings. Layer thickness has been determined by prolilometry and the eddy current method, while modifications in surface wettability have been evaluated through contact angle measurements. It has been observed that, under certain experimental conditions, the treatments have enhanced the resistance to salt spray corrosion up to 145 times, as compared to the pristine substrates.

Resumo: Percevejos do gênero Atopozelus (Hemiptera: Reduviidae) são nativos da região Neotropical, com cinco espécies descritas e apenas três com registro no Brasil. Em agosto de 2007, no município de São Simão, estado de São Paulo, folhas de Eucalyptus camaldulensis infestadas por Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Psyllidae) foram amostradas e nelas foi encontrado indivíduos de um pequeno percevejo verde, que se alimentava de psilídeos. Os percevejos foram identificados como Atopozelus opsimus (Elkins, 1954). Devido à recém descoberta desse predador e a escassez de informação sobre sua bioecologia, este trabalho objetivou estudar a morfologia e morfometria externa, o ciclo biológico e o comportamento de A. opsimus mantidos com G. brimblecombei em condições de laboratório (26 ± 2 oC, 70 ± 10% UR e fotofase de 13 horas). O estudo morfológico e o morfométrico possibilitaram caracterizar todos os estágios de desenvolvimento. Os parâmetros avaliados na biologia foram: duração e viabilidade do estágio ninfal, longevidade dos adultos, viabilidade e número de ovos por fêmea, número de posturas por fêmea, duração do período de incubação e do ciclo total. O percevejo apresentou cinco instares ninfais com duração total de 40, 3 ± 1,40 dias. Fêmeas apresentaram longevidade de 61,0 ± 8,0 e machos de 39,0 ± 5,1 dias. Ambos apresentaram ciclo médio total de vida longo de, 120,2 ± 8,4 e de 92,5 ± 5,9 dias para fêmeas e machos, respectivamente. Desde o primeiro estádio o percevejo se alimentou tanto de ninfas quanto de adultos do psilídeo-de-concha e também apresentou fitofagia e onivoria. Os adultos demonstraram capacidade de retirar a cobertura que protege os psilídeos. As fêmeas apresentaram cuidado parental e ensinam as crias onde buscar alimento.

Abstract: Predatory bugs of genus Atopozelus (Hemiptera: Reduviidae) are native from Neotropical region, with five described species and three registered in Brazil. In August, 2007, in São Simão, state of São Paulo, Brazil, leaves of Eucalyptus camaldulensis infested by red gum lerp psyllid were collected and it was observed the presence of a small green bug, which feed on psyllids. The bug was identified as Atopozelus opsimus (Elkins, 1954). Due to the recent discovery of this predator and to the existence of few information of its bioecology, this study aimed to characterize external morphology and morphometry, life cycle and behavior of A. opsimus maintained in Glycaspis brimblecombei (Moore, 1964) in laboratory conditions (temperature of 26 ± 2 oC, 70 ± 10% RH and photophase of 13 h). The morphological and morphometric studies helped to observe the differences between development stages. Considering biology study, the parameters evaluated were: duration and viability of nymphal stage, adults longevity, number and viability of eggs per female, number of ovipositions per female, duration of incubation period and the total life cycle. The predator had five nymphal instars with total duration of 40.3 ± 1.40 days. Female and male longevity were 61.0 ± 8.0 and 39.0 ± 5.1 days, respectively. Both sexes have total life-cycle with 120.2 ± 8.4 and 92.58 ± 5.9 days for females and males, respectively. Since first stage the bug fed on nymphs and adults of red gum lerp psyllid, presenting phytophagy and omnivorous, too. Adults had ability to remove the lerp that protects psyllid nymphs. Females had maternal care and teaches the offspring where they get food. A. opsimus shows unusual features of the various biological control agents found in the nature, and become a promising agent in biological control programs in Eucalyptus spp. plantations infested by G. brimblecombei.

O nome Conselho Tutelar já explicita um processo de governo e sujeição de corpos. Levantamos a hipótese de que o objeto dessa gestão são as crianças e adolescentes das camadas populares, categorizados como estando em risco psicossocial. Não que a infância de outras classes sociais não seja tutelada, elas também o são, porém são outros os mecanismos de controle exercidos sobre elas, como nos apontam Margareth Rago (1985) e Jacques Donzelot (1986). Consultamos os registros das denúncias e de seus desdobramentos, efetuados no período de 1994 a 1996, nos arquivos da referida instituição, em um município do interior paulista. Interrogamos esse regime de escrita e de construção de dossiês que transformam cada indivíduo em um caso, permitindo comparar, classificar e controlar crianças e adolescentes e seus familiares. Em nossas análises, indicamos que as práticas dos conselheiros tutelares normalizam e moralizam os corpos que tomam como alvo de intervenção, psicologizam a violência familiar, atribuem uma determinação econômica aos atos de violência familiar, culpabilizam as famílias pela situação em que se encontram as crianças e os adolescentes, ameaçam as famílias de perda do pátrio-poder e imprimem um caráter policialesco às suas ações. As práticas desses atores institucionais caracterizam-se como uma gestão dos riscos, baseadas em uma visão médico-higienista da infância e de um processo de normalização e moralização das famílias populares.
Abstract: Starting from a genealogical historic look proposed by Michel Foucault, we questioned the Tutelary Counselors' practices facing the household violence accusations, asking what relationships of knowledge and power support these practices and what outcomes they throw into our society. The violence, childhood and family objects, and the institutions of protection and attendance to children and adolescents were considered as historic products. The name Tutelar Council already makes a process of body subjugation and control explicit. The hypothesis that the object of this administration are the children and adolescents of popular classes, distinguished as being in psychosocial risk, was raised. Not that the childhood in other social classes are not tutored, they also are, however the control mechanisms performed over them are different, as shown by Margareth Rago (1985) and Jacques Donzelot (1986). The accusation reports and their development, executed between 1994 and 1996, were checked in the mentioned institution files, in a São Paulo countryside city. The writing method and making of dossiers that change each individual into a case, allowing to compare, classify and control children and adolescents and their families were questioned. In our analysis, we point out that the tutelary counselors practices standardize and moralize the bodies taken as na intervention aim, psychologize the familiar violence, assign na economical determination to the acts of familiar violence, blame the families for the situation in which the children and adolescents are, threaten the families of parents' rights loss and print a police charater into their actions. These institucional actors practices define themselves as a risk administratio, based on a medical hyginist view of the childhood and of a popular families' standardization and moralization process.

Resumo: A Internet vem modificando substancialmente os hábitos de pesquisa do ser humano, por um lado permitindo-lhe maior agilidade e eficiência na obtenção de informações, mas, por outro, multiplicando problemas de direito autoral nas obras por ela veiculadas. Desse modo, torna-se necessário analisar, no âmbito doutrinário, legislativo e jurisprudencial brasileiro, os direitos autorais (intelectuais e materiais) e sua aplicabilidade às criações dispostas na rede, ao que se aliam questões como a de controle das cópias de tais publicações e a de meios para evitar falsificações, adulterações e uso indevido das mesmas. Valendo-se de pesquisa documental em fontes do direito e em informações da própria rede, parte-se da abordagem da Internet em seu conceito, características e tipos de documentos, analisam-se os direitos autorais em termos teóricos (conceito e modalidades) e aplicados (controle e proteção no Direito Brasileiro) e discute-se a utilização de alguns elementos para a proteção dos direitos autorais na Internet: Criptografia, Assinatura Digital, Certificação Digital e Marca d'Água Digital, concluindo-se pela natureza eminentemente diplomática dos mesmos. Verifica-se que a Criptografia, enquanto código, é a linguagem por meio da qual se apresenta o documento, podendo ser caracterizada, dentro dos elementos que compõem a estrutura documental, como um elemento externo, sob a ótica diplomática. Já a Assinatura Digital caracteriza uma subscrição, ou seja, a assinatura do autor nos documentos digitais, sendo dessa forma caracterizada como um elemento de estrutura interna do documento. A Certificação Digital representa uma espécie de precação, pois é por seu intermédio que se tem a certeza da legalidade do documento. Essa ferramenta é comparada a um sinal de validação ou uma assinatura testemunhal, ficando, assim... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The Internet has been substantially changing the research habits of human beings, on one hand providing them more agility and efficiency for obtaining information, but on the other hand it increases problems related to copyright in works that the net can spread. Consequently, it is necessary to analyse, in Brazilian doctrinal, legislative and jurisprudencial scopes the copyright (intellectual and material) and its apply to the creations on the net, to which are related questions such as the control of publications copies and the means to avoid falsifications, adulterations and inappropriate use of them. Based on documentary research, on law and also on information from the net, starting from the Internet approach in its concept, characteristics and types of documents, it is analysed the copyright in theoretical (concept and kinds) and applied (control and protection in Brazilian law) terms and it is discussed the use of some elements to protect copyright on the Internet: Cryptography, Digital Subscription, Digital Certification and Digital Watermark, and it is concluded with the diplomatic nature of the same. It is verified that the Cryptography, as a code, is the language through which the document is presented, and it can be characterized, among the elements that form the documentation structure, as an outer element, under the diplomatic view. The Digital Signature characterizes a subscription, that is, the author's signature on digital documents, it is therefore, featured as an element of the document inner structure. The Digital Certification represents a kind of precation because it proves the legality of the document. This tool is compared to a validating sign or to a testifying signature, being featured by diplomatic as an inner element of the documentation structure. Finally, it is verified that the Digital Watermark is compared to a special... (Complete abstract, click electronic address below)

Resumo: O autor procurou na presente dissertação demonstrar que o instituto da antecipação da tutela configura uma forma de prestação jurisdicional mais célere no que se refere à concessão de benefícios previdenciários, estando em plena consonância com os princípios constitucionais da efetividade do processo e da dignidade da pessoa humana. Pretendeu evidenciar que a possibilidade de revogação da tutela concedida, em virtude de improcedência do pedido ao final do processo, com a conseqüente suspensão do benefício previdenciário anteriormente implantado, não pode ser invocada como empecilho à utilização deste instituto, pois a Seguridade Social engloba a Previdência Social, a Assistência Social e a Saúde, permitindo ao Estado alocar em qualquer dos orçamentos as verbas destinadas a este fim, se necessário. Buscou esclarecer que as tentativas do Instituto Nacional do Seguro Social (INSS) de reaver as quantias pagas em decorrência de decisões de antecipação da tutela posteriormente revogadas, por meio de execução nos próprios autos ou ação executiva autônoma, não devem prosperar, observada, dentre outros motivos também analisados, a natureza alimentar da verba. Os dados levantados na pesquisa revelaram que a antecipação da tutela, nos processos cujo objeto é a concessão de benefícios previdenciários, é um instrumento processual do qual o autor (segurado) não pode prescindir, na medida em que traz efetividade ao processo e, por conseqüência, à Justiça. A pesquisa demonstrou, ainda, que mesmo não sendo requerida pelo autor (segurado), a medida antecipatória deve ser utilizada de forma incessante por todos os magistrados que analisam as ações de concessão de benefícios previdenciários, ante o inegável resultado prático por ela causado, com solução rápida e eficiente de controvérsias que antes perduravam por diversos anos
Abstract: In this study, the author aimed at demonstrating that the advance protection institute is a faster way of providing jurisdictional service as regards Social Welfare benefits grant, which completely agrees with the constitutional principles of effective lawsuit and human being's dignity. It was shown that the possibility of having the granted protection repealed by virtue of an unfounded request at the end of the lawsuit which could result in the interruption of the Social Welfare benefits previously established cannot be considered as a hindrance to the use of this institute. This is due to the fact that Social Security comprises Social Welfare, Social Assistance and Health, making it possible for the State to assign the amount needed to the budget of any of the departments cited above, if necessary. The author also tried to clarify that the attempt of the National Institute of Social Insurance (INSS - Brazil) to get back the paid amount of money on advance protection decisions later repealed by execution on law documents or by executive autonomous action must not succeed owing to the reasons analyzed, including the protection's nourishing nature. Furthermore, the data showed that the advance protection in lawsuit whose goal is the granting of Social Welfare benefits is a legal instrument which the insured cannot be dispensed of as it provides effectiveness to the lawsuits and, as a consequence, to Justice. The research has also indicated that, even if the insured has not required the advance protection, this must be incessantly used by all the Magistrates that analyze the granting of Social Welfare benefits actions, in view of the good results it causes, fast and efficient solutions to controversies that used to last for years

Resumo: A Geoecologia da Paisagem proporciona a elaboração de zoneamentos geoambientais fundamentados em uma análise sistêmica, na qual os componentes antrópicos e naturais se integram a partir de uma caracterização socioeconômica e geoecológica da área estudada. Neste contexto, a presente pesquisa teve como objetivo geral elaborar o zoneamento geoambiental e funcional da área urbana do município de Cubatão-SP por meio da proposta metodológica de Rodriguez; Silva e Cavalcanti (2004) na escala 1:10.000. A escolha dessa área de estudo se deu devido a complexidade desse sistema ambiental litorâneo frente as atividades antrópicas desenvolvidas ao longo dos séculos no município, as quais tem corrompido a capacidade desse em suportar impactos ambientais. A pesquisa teve como respaldo metodológico os princípios que concernem à Teoria Geral dos Sistemas, procurando compreender a área urbana do município de Cubatão-SP como um sistema aberto. Ademais, estes princípios fundamentam a proposta metodológica de Rodriguez; Silva e Cavalcanti (2004). A caracterização socioeconômica e geoecológica da área de estudo foi realizada a partir da elaboração de distintos materiais cartográficos, em que a correlação entre esses resultou em três documentos cartográficos de síntese: Carta de Unidades Geoambientais; Carta de Estado Geoambiental e Carta de Zoneamento Geoambiental e Funcional. A Carta de Unidades Geoambientais possibilitou a identificação das paisagens dos sistemas Serrano e Planície Quaternária mais susceptíveis ao desenvolvimento de processos naturais e, ainda, aquelas fragilizadas devido as intervenções antrópicas.

Abstract: The Geoecology provides the development of geoenvironmental zoning based on a systemic analysis, in which the natural and anthropic components are integrated by geoecological and socioeconomic characterization of the studied area. This research aimed to establish the functional and geoenvironmental zoning of the urban area of the city of Cubatão - state of São Paulo (SP) - through the methodology proposed by Rodriguez; Silva and Cavalcanti (2004) on scale of 1:10.000. The choice of this area was due to the complexity of this coastal environmental system in view of human activities developed over the centuries in the city, which has corrupted its ability to withstand such impacts. The research was supported by the methodological principles of the General Systems Theory, seeking to understand the urban area of Cubatão-SP as an open system. Besides, these principles underlie the methodology proposed by Rodriguez; Silva and Cavalcanti (2004). The geoecological and socioeconomic characterization of the studied area was made from the development of different cartographic materials, and the correlation between them resulted in three cartographic documents of synthesis: Geoenvironmental Units Map, Geoenvironmental Conditions Map and Functional and Geoenvironmental Zoning Map. The Geoenvironmental Units Map enabled the identification of landscapes of Mountain and Quaternary Plain systems that are more susceptible to development of natural processes, and also those ones that are fragile due to human interventions. The Geoenvironmental Conditions Map allowed to verify the conditions for regulating the geoecological functions of the environmental units in the face of human interventions. Finally, the Functional and Geoenvironmental Zoning Map revealed conflicts and/or adjustments of current land... (Complete abstract click electronic access below)

Abstract:

Resumo: Na sua quase totalidade, as formas farmacêuticas líquidas apresentam agentes conservantes em suas fórmulas visando a proteção contra o desenvolvimento microbiano. Entretanto, pesquisas indicam que conservantes são substâncias tóxicas, pois dependendo da concentração administrada podem provocar reações adversas ou intoxicações. A inclusão desses agentes na fórmula de um medicamento deve seguir rigorosamente os parâmetros de eficácia e segurança, garantindo assim proteção antimicrobiana máxima sem provocar danos aos usuários. Por essas razões, este estudo teve como objetivo analisar os possíveis impactos na qualidade das dispersões moleculares de uso oral comercializadas no Brasil em decorrência das alterações na concentração de excipientes no pós-registro de medicamentos, em especial a modificação "moderada" de conservantes (5 - 10%). Foram analisadas as fórmulas de todas as dispersões moleculares de uso oral, de referência, registradas na ANVISA em março de 2009, e os respectivos sistemas conservantes foram identificados. A elaboração de uma matriz "medicamentos versus sistemas conservantes" propiciou a definição dos principais sistemas conservantes empregados industrialmente e sua inserção em oito fórmulas de bancada. Os testes de efetividade antimicrobiana realizados nestas fórmulas indicaram que metade delas não atendeu aos critérios de aceitação propostos na monografia oficial (USP 32), além de outras duas que apresentaram frágil proteção antimicrobiana, pois nelas o crescimento microbiano esteve muito próximo do limite máximo permitido. Em se tratando dos riscos que tais alterações possam provocar na conservação de um medicamento, estes valores são preocupantes, especialmente em escala industrial e, no mínimo, as fórmulas não aprovadas deveriam ser retestadas
Abstract: Almost all liquid dosage forms have preservative agents in their formulas in order to protect against microbial growth. However, researches indicate that preservatives are toxic, because depending on the administered concentration they can cause adverse reactions or intoxications. The inclusion of these agents in the formulation of a product should strictly follow the parameters of efficacy and safety, thus ensuring maximum antimicrobial protection without causing harm to users. For these reasons, this study aimed to examine the possible impacts on the quality of molecular dispersions for oral administration commercialized in Brazil as a result of changes in the concentration of excipients in the post-registration of medicines, particularly the "moderate" modification of preservative agents (5 - 10%). All formulas of molecular dispersions for oral use, as reference drugs, recorded at ANVISA in March 2009 were analyzed and the preservative agents were identified. The development of a matrix "drugs versus preservative systems" led to the definition of major preservative systems used industrially and their inclusions in eight formulas studied. The antimicrobial effectiveness tests conducted on these formulas indicated that half of them did not meet the acceptance criteria proposed in the official monograph (USP 32), beyond two other formulas that presented weak antimicrobial protection, because microbial growth in them was very close to the maximum allowed. Considering the risks that such changes may result in the conservation of a drug these negative values are worrisome, especially on an industrial scale and, at least, the formulas not approved should be retested

Resumo: O interesse pelos problemas da efetivação dos direitos, em especial, dos direitos dos idosos, após o advento do Estatuto do Idoso, Lei nº 10.741, de 1º de outubro de 2003, levou-nos à pesquisa de instrumentos para concretizar a obtenção dos referidos direitos. Após transpor as várias etapas da vida, os idosos encontram obstáculos econômicos, sociais e materiais para ter uma vida com dignidade, com respeito. A sociedade, a família e o Estado têm deveres para com os idosos, que se houvesse o reconhecimento natural de referidos deveres, não haveria a necessidade de positivar normas morais com escopo de proteção destes, pois são direitos humanos inerentes à sadia condição de vida. Reconhecidos os direitos nos planos constitucional e infraconstitucional, cabe a sua efetivação espontânea, ou através do Poder Judiciário. O processo civil é instrumento a aperfeiçoar e concretizar os direitos dos idosos. Porém, o fator tempo evidencia que os direitos não podem esperar. As tutelas de urgência do processo visam a abreviar a espera pela consecução dos direitos. A insuficiente política pública relacionada aos direitos dos idosos e a negação de recursos públicos para a consecução dos programas de apoio a eles são as justificativas mais freqüentes. Então, dentre os mais variados meios processuais cabíveis à proteção do cidadão, a tutela jurisdicional deve fazer valer os direitos humanos inerentes aos idosos, em face dos Poderes Públicos, da família do idoso e da sociedade.

Resumo: Neste trabalho apresenta-se uma metodologia para obter um ambiente interativo de simulação com ferramentas que permitam fazer análises de sistemas de proteção como estudos de coordenação e analises pós falta. As ferramentas estão baseadas no programa de simulação de transitórios eletro- magnéticos EMTP/ATP e na linguagem de programação ANSI C, sobre a plataforma de software livre GNU/Linux. Esta metodologia pode ser implementada, da mesma forma, em qualquer plataforma Windows sobre a qual possa funcionar o EMTP/ATP e o pacote ATP/MingW. Assim, implementou- se um relé de distância numérico através de modelos externos ("foreign models"). Ilustra-se também como usar arquivos no formato COMTRADE na análise com EMTP/ATP. Dessa forma foi possível analisar o comportamento do relé implementado tendo como entradas os sinais de tensões e correntes correspondentes aos eventos reais. Os sinais de disparo, assim como os demais componentes do relé, foram testados usando um sistema teste de referência do Power System Relaying Committee da PES-IEEE e os sinais de faltas reais do Sistema Elétrico Interligado da Colômbia. Por fim, foi feito um estudo de coordenação. Os resultados são apresentados e discutidos. A metodologia proposta pode ser usada para desenvolver qualquer componente ou elemento de controle dentro de um sistema elétrico, onde haja a necessidade de usar o EMTP/ATP para simular condições específicas de operação do sistema elétrico, complementando a simplicidade da linguagem MODELS com a portabilidade e potencialidade da linguagem C
Abstract: This work presents the methodology to obtain an environment of interactive simulation with tools to perform analysis of protection systems, coordination studies and analysis post fault.

The same methodology can be followed to be used on any Windows Operating System that can run EMTP/ATP and the package ATP/MingW. Then, for this, a numerical distance relay was implemented by means of foreign models using C programming language. It also shows how to use COMTRADE files in analysis with EMTP / ATP. Thus it was possible to analyze the behavior of the implemented relay with voltage and current signals of real events as inputs. The trip signals, like the other components of the relay, were tested using a testing reference system of Power System Relaying Committee of PES-IEEE and the signals of real faults of Inter- connected Electric System of Colombia. Finally, a coordination study was made. The results are presented and discussed. This methodology could also be used to develop any component or control element within an electrical system that one may need for a particular use; therefore, compensating the simplicity of the language MODELS with the flexibility and portability of C programming language

Resumo: O processo de globalização intensificou as relações comerciais entre os países no final do Século XX, tornando mais freqüentes práticas empresariais desleais como o dumping e a respectiva utilização da legislação pertinente pelos países participantes do comércio internacional. A aplicação de medidas antidumping para neutralizar os efeitos da prática desleal protege a concorrência em benefício dos empresários do país importador, entretanto, se essas medidas forem aplicadas com finalidade protecionista, prejudicam a livre concorrência, impedindo a entrada de produtos estrangeiros em condições de concorrência com os produtos nacionais. As análises realizadas demonstraram que a legislação brasileira antidumping, de forma genérica, encontra-se em consonância com as normas da Organização Mundial do Comércio (OMC), que direcionam a aplicação de medidas antidumping no âmbito mundial. Apesar da evolução verificada na Rodada Uruguai, o estudo demonstrou a necessidade de algumas alterações na legislação antidumping da OMC para impedir a possibilidade de diferentes interpretações às normas antidumping pelos Países-Membros. As alterações devem proporcionar maior precisão a alguns conceitos presentes na legislação, como os referentes ao valor normal e à comprovação de dano, devendo também impor a aplicação de direitos antidumping em valores suficientes apenas para neutralizar os efeitos da prática desleal. A revisão da legislação antidumping mostra-se fundamental para a consolidação das normas antidumping no âmbito mundial e, sobretudo, para assegurar sua finalidade de proteger a concorrência em benefício dos empresários locais, sem causar prejuízos à concorrência internacional.
Abstract: The globalization process increased commercial relations among the countries at the end of the twentieth century, making more frequent disloyal enterprise practice like dumping and the respective utilization of apt legislation towards countries of the international trade. The aplication of antidumping measurement to neutralize the effects of disloyal practice protects the competition in the businessmenþs benefit of importer country, howerver, if these measures were applied with protecting goals they would damage the free competition, holding back the entry of foreign products in terms of competition, holding back the entry of foreign products in terms of competition with the national products. The analysis made, show that antidumping brazilian legislation, in general, is along with the rules of the World Trade Organization (WTO), that take control of the aplication of antidumping measures in the world. In spite of the evolution checked in the Uruguay Round, the study showed the necessity of some alteration in the antidumping legislation of the WTO to avoid the possibility of different interpretations at antidumping rules from member countries. The alterations have to bring bigger precision in some concepts that are present in the legislation, like the referent to the normal value and the damage checking that must impose the application of antidumping dues in enough values only to neutralise the disloyal practice effects. The review of antidumping legislation shows itself essential to the antidumping rules consolidation in the world and, above all, to assure its purpose to protect the competition into the benefit of local businessmen, without causing impairments to the international competition.

Resumo: Neste estudo buscou-se conhecer a realidade concreta do trabalho juvenil diante dos avanços jurídicos, bem como das várias transformações ocorridas no mundo do trabalho hoje. Partiu-se do pressuposto de que a ambigüidade entre o factual e o legal e a necessidade da reversão desta realidade só se efetivará com um conjunto de ações integradas no tempo e espaço, pelas diferentes políticas publicas. O objetivo geral deste estudo, portanto, é analisar o processo de inserção do adolescente no mundo do trabalho, contribuindo para a ampliação do conhecimento científico sobre a questão social "mundo do trabalho e trabalho juvenil". Para alcançá-lo, determinou-se como objetivos específicos: delinear a visão dos representantes dos vários órgãos envolvidos com a proteção dos direitos dos adolescentes no que tange ao trabalho; identificar as atividades produtivas, as condições de trabalho e a remuneração dos adolescentes pesquisados; verificar o grau de escolaridade e dificuldades encontradas pelos adolescentes relacionadas à Instituição Escola; constatar se a inserção profissional oportuniza a capacitação profissional. Para tanto, foram entrevistados adolescentes trabalhadores e representantes dos órgãos públicos do município de Bauru, Estado de São Paulo, ligados diretamente à questão. Os dados levantados demonstraram que o trabalho juvenil, embora existindo um aparato legal, continua trilhando por caminhos que necessitam de cuidados e revisões especiais para a formação da cidadania dos homens do amanhã, do contrário, frente à vulnerabilidade do segmento, estar-se-á sacramentando a exclusão social.
Abstract: This study searches to know the exact reality of the youthful labour in front of the legal advances, as well as the many transformations occurred nowadays in the working world. The presupposition used was the ambiguity among the factual and the legal, as also the need of reversion of this reality, that will only take place within an entire collection of integrated actions in time and space, done by the different public policies. The general objective of this study is, therefore, to analyse the process of teenager introduction in the working world, contributing to the amplification of the scientific knowledge about the social question "working world and youthful labour". In order to reach this, the determinated specific objectives were: sketch the vision of the representatives of several institutions involved in the protection of children rights as regards as the work; identification of productive activities; the conditions of the work and the remuneration of the investigated teenagers; find out the school degree and the difficulties faced by the teenagers related to the School Institution; confirm if the professional insertion opportunises professional capacity. So, worker teenagers had been interviewed as well the representatives of the public institution of Bauru Town, São Paulo State, Brazil, which were connected to the question. The raised up reports show that the youthful labour, although the legal pageantry, continues on a way that needs attentions and special revisions to be able to form the citizenship of the future men, otherwise, because of the segment vulnerability, the social exclusion will have been assumed.

Resumo: Este estudo teve por objetivo compreender a atuação do Conselho Tutelar de Orlândia-SP no fenômeno da violência doméstica contra crianças e adolescentes. O Conselho Tutelar é o órgão que, de acordo com o Estatuto da Criança e do Adolescente, é responsável por receber denúncias de suspeitas ou confirmação de situações de maus tratos, exploração, abuso e negligência impostas pelos pais ou responsáveis. É, portanto, através do Conselho Tutelar que a violência contra crianças e adolescentes praticada no interior da família sai do espaço privado para o público, adquirindo visibilidade social e exigindo, deste órgão, a aplicação de medidas de proteção. Para concretizarmos nosso estudo, realizamos o levantamento de dados através de pesquisa documental, consultando os prontuários de atendimento do Conselho Tutelar e coleta de relatos orais. Identificamos, no período de janeiro a novembro de 2003, 26 denúncias desta forma de violência. Com a realização de entrevista com um conselheiro tutelar e com dois profissionais da área da saúde e educação, coletamos informações sobre a atuação do Conselho Tutelar, assim como sobre as medidas adotadas por instituições de atendimento a crianças e adolescentes ao identificarem uma situação de violência doméstica. O Conselho Tutelar, tendo conhecimento de denúncias desse tipo de violência, toma medidas no sentido de se constatar a procedência ou não da mesma, entretanto, no que diz respeito às medidas de proteção à vítima, contatamos que estas nem sempre ocorrem. Esperamos que este estudo venha a propiciar reflexões sobre tão polêmico e candente tema e que essas reflexões possibilitem ações mais efetivas de proteção às crianças e aos adolescentes vítimas de violência doméstica em Orlândia, assim como sirvam de motivação para estudos posteriores.
Abstract: This study had as an objective to understand the performance of the Tutelary Advice of Orlândia-SP in the phenomenon of the domestic violence against children and teenagers. The Tutelary Advice is an organ that, in accordance with the Child and the Teenager Statute is in charge of receiving denunciation of suspicious or confirmation of situations of maltreatment, exploration, abuse and negligence imposed by the parents or responsible people. Therefore, it is through the Tutelary Advice that the violence against children and teenagers practised inside the family leaves out the private space for the public, then being acquired a social visibility and demanding from this organ, the application of protection means. To materialize our study, we made a data-collecting through documentary research, by consulting attendance handbooks of Tutelary Advice and by collecting verbal stories. We have identified in the period from January to November 2003, 26 claims of this form of violence. With the accomplishment of the interview with a Tutelary Council member and two professionals of the health area and education so we have collected information on the Tutelary Advice, as well as on the means adopted by the assistance institutions for the children and teenagers when identifying a situation of domestic violence. The Tutelary Advice when having knowledge of denunciations of this type, takes steps in the sense of checking the origin or not of the same one, however, in what measures of protection to the victim is concerned, we have verified that these procedures not always occur. We hope that this study come to provide reflections on this so controversial and cadent subject and that these reflections make possible more effective protection actions to children and teenagers who are victims of domestic violence in Orlândia-SP, as well as to be a motivation for further studies.

Neste contexto, utilizam-se ferramentas computacionais consolidadas, como o ATP (Alternative Transients Program), que combinado a um software desenvolvido em Visual Basic, permitem quantificar e avaliar o nível de sobretensões nas linhas de distribuição. Por meio de modificações nas técnicas clássicas de modelagem das descargas atmosféricas, foi possível a construção de um software em Visual Basic capaz de quantificar os valores das tensões induzidas em linhas de distribuição finitas. A avaliação dos níveis de sobretensões induzidas nas mesmas foi implementada pela associação deste software a um programa de simulação (ATP), a fim de se obter resultados fidedignos deste transitório. Tais resultados foram utilizados para se avaliar o desempenho das... (Resumo completo, clicar acesso eletrônico abaixo)

Resumo: A situação das crianças e adolescentes ameaçados ou violados em seus direitos básicos, em Franca, não é diferente da maioria das cidades brasileiras. Há ainda um longo caminho a ser percorrido no sentido da proteção integral, no entanto, os passos que já foram dados servem de experiência acumulada para os próximos. O resgate histórico da construção da política voltada à criança e ao adolescente em Franca, mais do que um registro desta experiência - que traz características comuns a outros municípios, visto que faz parte de uma totalidade, mas que também contém traços particulares - pretendeu verificar e demonstrar como são percebidas as contradições no âmbito municipal e no cotidiano de quem lida com esta realidade de perto. Mais do que compreender este universo, o presente estudo procurou investigar se existem possibilidades de contribuir - por parte daqueles que têm a oportunidade de participarem da elaboração das políticas sociais - com a efetivação dos direitos e não, ao contrário, com a efetivação da dominação, atenuando os conflitos sociais decorrentes das precárias condições de vida a que se encontram submetidas as classes subalternas. Utilizamos metodologia qualitativa, entrevistando alguns dos sujeitos que participaram e/ou participam de alguma forma na elaboração da política voltada à criança e ao adolescente na cidade de Franca e realizamos observação participante no Conselho Municipal dos Direitos da Criança e do Adolescente e no programa "Rede Criança/Adolescente" (da prefeitura municipal). Juntando as vivências, as percepções, as interpretações, os conhecimentos, é que conseguimos identificar os desafios, mas principalmente, as possibilidades de atuação através da política social a favor, enfim, das crianças e adolescentes.
Abstracts: The situation of children and adolescents threatened or violated in their basic rights in Franca is not different from the most of the brazilian cities. There is a long way to pass through in the path of total protection, however, the steps that have been given serve as accumulated experience for the next ones. The historic of the political construction turned to the child and adolescent in Franca, more than just a register of this experience - what brings common characteristics to other cities, seen as part of a totality, but even have particular lines - pretend to verify and demonstrate how the contradictions are understood in the municipal field and the daily of a person who nearly deals with this reality. More than to this universe, the present study tried to investigate if there are possibilities to contribute - for the ones who have the opportunity to participate at the social politics elaboration - with the effective rights of the domination, diminishing the social conflicts originated from the life contradictions in wich the subordinated from the life contradictions in wich the subordinated classes are submitted. We use qualitative methodology, interviewing some people who have participated or are still participating in any way children and adolescent in the city of Franca and we do participant observation at the Municipal Consil of the Children and Adolescent Rights and at the "Child/Adolescent Net" (from the Municipal Aty Hall) Adding the existences, the perceptions, the interpretations, the knowledge, we can identify the challenges, but mainly, the possibilities of acting through social politics in favor of, at last, the children an adolescents.

Abstract: The Serra do Mar State Park, specifically in the area that encompasses the Santa Virgínia Nucleus, includes the northern portion of the Atlantic Forest in the State of São Paulo, Brazil. The park is considered a very important area in biological and cultural terms and has been subjected to human threats and pressures, causing degeneration and loss in both biodiversity and in cultural traditions and identities. An advisory board was set up to operate on the principle of participated management, as a space for dialogue between the local community living in the park, and the park itself. The perception and environmental interpretation by the nucleus's board members is the central topic of this thesis, based on research aimed at fostering participated environmental management. The research is aimed at discussing the relationship of the board members and their environmental experiences with the natural and cultural environment. The project also calls for joint work with the members to draw up indicators for evaluating their performance on the board. The conceptual bases used in the research were the ecology of the landscape and the human geography, which served as the bases for the analyses of the space and environment where the board members live. To study the data obtained from bibliographic and documentary sources, the investigation used experimental research methods, including field visits, participated observation of meetings, the application of a questionnaire, interviews and a planning workshop with the board members. The dynamics of their participation and their interpretation of the work they themselves carried out on the board is also analyzed here. The discussion explores the cosmovision and the board members' processes of subjectivation and identification, on the basis of social representations, in the...

Resumo: Esta pesquisa aborda a política socioeducativa de direitos para o adolescente em conflito com a lei, com ênfase nas medidas socioeducativas executadas no município de Maringá, localizado na região Norte do Estado do Paraná. Essa política se encontra no arcabouço jurídico-institucional (lei e sistema) Estatuto da Criança e do Adolescente (ECA), Lei Federal nº 8.069/1990, voltada para a proteção integral de crianças e adolescentes até 18 anos de idade e, em condições especiais, entre 18 e 21 anos. O estudo de base analíticodocumental tem como objetivo a análise qualitativa da política socioeducativa de direitos, observando os quesitos sobre o cumprimento das decisões judiciais, quando inserida em programas socioeducativos, tomando como referência os aspectos da execução, natureza, tipologia, modalidades e financiamento. A abordagem qualitativa segundo Minayo (2007(a)) aprofunda-se no mundo dos significados, o qual deve ser exposto e interpretado primeiramente pelos próprios sujeitos pesquisados. Na presente investigação, a observação e a análise documental com pesquisa de campo (entrevistas semiestruturadas) embasaram a compreensão e a síntese desta. Para a consecução da análise foram entrevistados: conselheiros municipais dos direitos da criança e do adolescente, conselheiros tutelares, educadores do Centro de Referência Socioeducativo e a Secretária Municipal de Assistência Social e Cidadania. As entrevistas foram consideradas a base empírica da pesquisa, quando foram destacados os limites e as capacidades apresentadas pelos sujeitos entrevistados na concretização da proteção integral e, nesse sentido, possibilitaram apreender as convergências e divergências indicadas na sua atuação prática.
Abstract: This research deals with the socio educational policy of rights for adolescents in conflict with the law, and it is focused on the socio educational measures in Maringá, a city in the Northwest of Paraná state. This policy is part of the Statute of the Child and Adolescent, whose basis is the law and system, and it is stated in the Federal Law # 8.069/1990, which is based on the integral protection of children and adolescents, until the age of eighteen and, in special conditions, for those who are between 18 to 21 years old. The study, based on analysis of documents, aims at the qualitative analysis of the socio educational policy of rights, observing the issues regarding the obedience to judicial decisions, when it is inserted in socio educational programs, taking into account their execution, nature, type, modality and financial aspects. According to Minayo (2007a), the qualitative approach goes deeply into the world of meanings, which must be shown and firstly interpreted by its own subjects. In the current investigation, observation and documental analysis, in addition to field research (semi structured interviews), were the basis for its understanding and synthesis. To carry out the analysis, city counselors for the right of children and adolescents were interviewed, as well as tutelary authorities and social educators from the Reference Center of Socio Education and from Municipal Socio-Citizenship Assistance Secretary. The interviews, considered the empirical basis of the research, when the limits and capacities of the interviewed subjects were mentioned, enabled to apprehend the agreements and disagreements indicated in their practical actions.

The analyses of what is electronic marketing, a new model of business transactions that is in fast growth should also be done. The virtual market appears inside this context, without obstacles, spreading to the entire globe, with no eyes for cultural differences, bringing uniformity to the world, not just in the way to shop but also on the products available. But not everyone has access to it, being this a big problem presented by the virtual establishment: the digital exclusion. In this work, there will be shown the necessity of development of ways to advance in the virtual technique, ways that show be the result of a critical and reflexive posture of the man, which is rarely seen now a days.

Abstract:

Short Message Service (SMS) has become a very commonly used service. It does not only work as a substitute for voice telephony, but is also used for automated services. Some of these service are related to security issues like SMS banking, or one time passwords, even though SMS messages can be spoofed or eavesdropped.We propose a design where we add security to SMS by making an easily configurable module that utilizes a fast cryptographic scheme called Elliptic Curve Signcryption. To prove our concept, we implement an SMS client for Android smart phones that utilizes our security module and serves end-to-end data protection of SMS messages with the same security level as Top Secret content.

Abstract:

Information plays a vast contributing role to all resources within an organisation. Organisations should recognise the importance of information and implement information security controls to protect their information as this will ensure that the organisation‟s information retains its confidentiality, integrity and availability. Information security controls, which are the means of managing information risks, rely heavily on the user‟s knowledge regarding the use of these controls for their effectiveness, and as such, users should be educated in order to maximise effectiveness of these controls. Current information security educational programmes are created without necessarily taking into account the target audience, who comprises of all employees, stakeholders, suppliers, third parties, customers or other external parties or third party that requires access to the organisation‟s information. This results in programmes that are not linguistically appropriate; or that present knowledge at an inappropriate level for the target audience. This could leave users bored or confused, without successfully changing their behaviour or improving knowledge. This dissertation identifies a baseline for information security knowledge targeted at end users. This was done by means of a Delphi Study, where a profile of “generic” end users comprised of information security topics and concepts were rated by experts from the field of information security education. This resulted in the elimination of inappropriate topics and concepts and retaining the relevant and appropriate aspects. This baseline for information security knowledge can be characterised as a minimum standard that everybody should be educated on as an introductory or refresher course. This can also serve as the foundation phase to educate end users with knowledge of the basic topics and concepts to enable them to fulfil their responsibilities in order to protect information. If needed, topics and concepts could be added to the baseline for information security knowledge for specialised target audiences (e.g. specialised End Users, ICT Staff or Top Management).

Full text

Abstract:

All organisms live in environments that are variable across space and time. Variation in selection across these environments may lead to the evolution of generalist genotypes that express phenotypic plasticity, in which one genotype can alter their phenotype (e.g., morphology, behavior, physiology) to match changes in environmental conditions, so that they may survive across a range of environments. In many egg-laying organisms that lack parental care, choosing an oviposition site is critical. The egg is an immobile stage of an animal's life cycle and mothers must balance a complex set of risks in deciding where to place their eggs. Because many biotic and abiotic factors are sources of selection on offspring survival, there is an advantage for females to evolve strategies in oviposition site selection to improve survival. This dissertation focuses on phenotypic plasticity in an offspring protection strategy that is triggered by natural enemies. In the seed beetle Mimosestes amicus (Coleoptera: Chrysomelidae: Bruchinae), females lay eggs on the outside of seed pods of legume trees and beetle larvae bore into and develop in the limited and discrete tissue of the seed. While most eggs are laid singly, I documented that beetle females superimpose eggs atop each other ("egg stacking") in response to the presence of egg parasitoids or parasitized eggs. In my first chapter, I investigated whether egg stacking is a strategy for protecting eggs from parasitism. In my second chapter, I examined female responses to variation in the number and dispersion of parasitized eggs on seed pods. Lastly, I investigated whether the intensity of stacking was affected by egg limitation (the risk of depleting her eggs before utilizing all hosts) or time limitation (losing reproductive ability or dying before laying all of her eggs). This study is unique in that it extends life history theory on egg and time costs to explain variation in egg protection behavior. The insights gained from this dissertation provide a foundation upon which we can examine how interactions among trophic levels impact the behavioral decisions made by insects that allow them to increase offspring survival.

Resumo: O controle químico, por meio de aplicações de agrotóxicos, destaca-se no combate aos organismos danosos às culturas agrícolas. Devido à toxicidade dos agrotóxicos, qualquer atividade onde se utiliza do controle químico, existe o risco de intoxicação dos trabalhadores e, portanto, há a necessidade de se adotar medidas de segurança. Acredita-se que os trabalhadores não estão convenientemente protegidos do risco de intoxicação com os Equipamentos de Proteção Individual (EPIs) confeccionados no país, por que ainda não têm a eficiência e a vida útil avaliadas em ensaios de laboratório ou de campo. Desta forma, objetivou-se avaliar com o procedimento da norma F 2130 da ASTM a eficiência dos tecidos hidrorrepelentes, em condições de laboratório, dos conjuntos de EPIs Bege Cru (100% algodão) e Camuflado (69% algodão/31% poliamida), usados por trabalhadores em pulverizações de agrotóxicos em culturas de cana-de-açúcar e de citros sem e com 5, 10, 20 e 30 usos e lavagens, e avaliar o uso da combinação da técnica de fotomicrografia dos tecidos com a técnica de análise de imagem quantitativamente, por meio das porcentagens de fibras e de poros dos tecidos para explicar as variações de repelência, retenção e penetração dos agrotóxicos nos materiais dos tecidos sem e após dez usos e lavagens. O tecido do conjunto Camuflado é mais eficiente que o do conjunto Bege Cru na proteção às formulações Supera SC® (hidróxido de cobre) e Roundup Original CS® (glyphosate). A combinação das técnicas de fotomicrografia e de quantificação percentual da porosidade por meio de software é adequada para avaliar a desorganização da estrutura física dos tecidos após usos e lavagens. A estrutura da porosidade do tecido do conjunto Camuflado não é alterada, mas a do tecido Bege Cru é alterada após os dez usos e lavagens em condições de campo
Abstract: Chemical control by spraying of pesticides, stands in combating organisms that damage agricultural crops. There is the risk of occupational poisoning in any activity where chemistry control is used for prevention and treatment of the agricultural crops, and it is necessary to adopt security measures. It is believed that workers are not satisfactorily protected from the risk of poisoning, because the Personal Protective Equipment (PPE) made in Brazil does not have its efficiency and life cycle adequately evaluated in laboratory or field testing. Stated thus, the present study has aimed to evaluate, by the procedure of F 2130 standard of ASTM, the efficiency of hidrorrepelent clothes, under laboratory conditions, from the sets of EPIs Bege Cru (100% cotton) and Camuflado ( 69% cotton / 31% polyamide), that were used by workers in activities of spraying of sugar cane and citrus crops with and without 5, 10, 20 and 30 uses and laundering, and to evaluate the use of a combination of the photomicrographs technical of clothes with the quantitative technique of image analysis, by the percentages of fibers and pores of the clothes to explain the variations of repellency, retention and penetration of pesticides in the clothes without and after ten uses and washes. It was concluded that the Camuflado cloth is more efficient than the Bege Cru, in both formulations of product crop protection used in laboratory tests with the application of the ASTM standard F2130. The combination of the techniques of photomicrography and quantifying the percentage of porosity by the software is suitable for evaluating disorganization of the physical structure of the clothes after using and washing.It was also concluded through the study that the porosity of Camuflado cloth (cotton/nylon) has not changed its structure after ten washes, however Bege Cru cloth (cotton) was altered

Abstract:

The adage, "old habits die hard", is especially relevant when humans learn new protective behaviors (i.e., dental flossing, IS security behaviors). The foundation that underlies many social-cognitive theories used in IS research is that intention to change predicts actual behavior change. Despite intentions to change, humans do not always change their habits due to actual or perceived obstacles, for example. In this study, user behavior, particularly with respect to vigilance over phishing attempts, was investigated via the theoretical lens of a hybrid continuum-stage behavior change model adapted from health-related fields. This type of model helps us to understand whether there are qualitatively different stages for adopting a more vigilant action plan toward phishing attempts, the number and ordering of distinct stages that a user must move through between forming an intention and subsequent behavior, what characterizes those stages, and how appropriate interventions at these stages can move a user to a higher stage of vigilant behavior. The goal of this research was to gain a better understanding of: a) whether there are distinct stages that distinguish end-users' vigilance toward phishing attempts; b) how many qualitatively different stages there are; and, c) what characterizes these stages. This study profiled IS end-users based on the model's constructs (e.g., coping self-efficacy, intention, action/coping planning, and risk perception) that examined end-users' protective behavior toward phishing attempts. In an exploratory analysis of survey data, stages of IS end-users were determined via cluster analysis techniques (hierarchical followed by K-means). A survey was administered to respondents (n= 394). Next, an agglomerative hierarchical cluster analysis using within-groups method of average linkage and Euclidean distance measures was performed on the model's constructs. Three clusters emerged as the optimal number to be used in the subsequent K-means cluster analysis. After conducting analyses for stability and validity for the 3-cluster solution, I compared the means of the model's constructs to develop profiles for the distinct three stages. I conclude that exploratory cluster analysis is an effective technique to discover natural groupings for protective behavior of IS end-users and propose future research to investigate stage-appropriate interventions to move users to higher stages.

Cavidades classe V, com dimensões padronizadas foram preparadas nas faces V e L de 20 terceiros molares humanos, divididos em 4 grupos de acordo com o material protetor pulpar e técnica de fotopolimerização: (1) Ketac Molar Easymix, 3M ESPE - (IVQ) + Fotopolimerização convencional - 850mW/cmø por 20s (FC); (2) IVQ + Fotopolimerização gradual - 100 mW/cm2 até 1000 mW/cm2 por 10s e 1000 mW/cm2 por 10s (FG); (3) Vitrebond 3M ESPE (IVR) + FC; (4) IVR +FG. Todas as cavidades foram restauradas com sistema adesivo Single Bond (3M ESPE) e resina composta híbrida Four Seasons (Ivoclar Vivadent). O aparelho fotopolimerizador utizado foi Optilux 501 (Demetron - Kerr) no modo convenciona e gradual (RAMP). Após ciclagem térmica um segmento longitudinal de 2 mm de espessura foi obtido na porção central de cada restauração e, em seguida, submetidos às etapas de fixação e desidratação em grau ascendente de etanol. A adaptação interna dos materiais à parede axial foi analisada em MEV, com 1000x de magnificação. A análise estatística realizada pela ANOVA a dois critérios de avaliação e pelos testes de Levene e Shapiro-Wilk (p_0,05) mostrou haver significância estatística entre as técnicas de fotopolimerização convencional e gradual (Ramp). Há evidência de que a fotopolimerização convencional produz, em 13 média, fendas maiores do que a fotopolimerização gradual.
Abstract: The aim of this study was to evaluate the influence of gradual photolymerization on the displacement of pulp protective materials due to the resinþs photopolymerization contraction trough the formation of gaps on the following interfaces: dental structure/ pulp protective material/ composite resin. Class V cavities with standardized dimensions were prepared on the buccal and lingual surfaces of 20 human sound third molars, divided into 4 groups according to their pulp protective material and photopolymerization technique:(1) Ketac Molar Easymix, 3M ESPE- (IVQ) + Conventional photopolymerization-850 mW/cm2 for 20 seconds (FC); (2) IVQ + gradual photopolymerization-100 mW/cm2 to 1000 mW/CM2 for 10 seconds and 1000 Mw/CM2 for 10 seconds (FG); (3) Vitrebond 3M ESPE (IVR)+ FC; (4) IVR + FG.All cavities were restored using the adhesive system Single Bond (3M ESPE) and hybrid composite resin Four Seasons (Ivoclar Vivadent). The device used for photopolymerization was the Optilux 501 (Demetron-Kerr) in both conventional and gradual (RAMP) modes. After thermal cycling, a longitudinal segment of 2 mm of thickness was obtained from the central part of every restoration, and submitted to fixation and dehydration with uprising levels of ethanol processes. The internal adaptation of the materials to the axial wall of the preparation was analyzed in 16 SEM with 1,000x of magnification. The statistical analysis was made using two-way ANOVA and Levene and Shapiro-Wilk (p _ 0,05) tests. Results showed statistically significant differences between the gradual (RAMP) and conventional photopolymerization techniques. There are evidences that the conventional technique creates wider gaps than the gradual technique.

La preparation d'analogues structuraux de l'acetate de nomegestrol, comportant diverses modifications en position 17, a constitue un des objectifs de recherche des laboratoires theramex.

L'utilisation des cetals glycoliques classiques ne convenait pas a cause de la grande sensibilite a l'hydrolyse acide des composes prepares.

L'hypothese de depart est verifiee: les groupements esters et amides de l'acide tartrique permettent, en effet, la stabilisation a l'hydrolyse acide des dioxolanes allyliques.

Abstract:

This work, within EPSRC LATEST2 (Light Alloys Towards Environmentally Sustainable Transport 2) Programme Grant, is focused on the development of environmentally-friendly corrosion inhibitors, nanocontainers loaded with inhibitors and epoxy coatings for corrosion protection of the aerospace alloy AA 2024-T3. More specifically, the electrochemical techniques of image assisted electrochemical noise, electrochemical impedance spectroscopy, split-cell technique and potentiodynamic polarization were used for the qualitative and quantitative evaluation and characterization of environmentally-friendly corrosion inhibitors on AA 2024-T3. Scanning electron microscopy observations complemented the electrochemical measurements. It was found that the organic inhibitor 2-mercaptobenzothiazole provides excellent corrosion inhibition properties to AA 2024-T3 in 3.5% sodium chloride solution. Among the tested nitrates, cerium nitrate provides the best inhibition performance. The concentration of the nitrate salt is critical in determining the corrosion protection. An excessive concentration of nitrate ions results in the dissolution of copper-containing oxides, increasing the corrosion rate. Different types of core-shell structured nanocontainers were synthesised with the methods of distillation precipitation polymerization, emulsion polymerization and sol-gel. The nanocontainers were characterized by scanning electron and transmission electron microscopy observations. The corrosion inhibitor 2-mercaptobenzothiazole was encapsulated into the nanocontainers. The encapsulation of 2-mercaptobenzothiazole was evaluated with energy dispersive X-ray analysis mapping micrographs from transmission electron microscopy measurements. Epoxy coatings with nanocontainers loaded with 2-mercaptobenzothiazole were applied on AA 2024-T3 for protection against corrosion. The corrosion protection properties of the coatings were evaluated with electrochemical impedance spectroscopy. The results indicated that epoxy coatings provide excellent barrier properties to AA 2024-T3 in the demanding environment of 3.5% sodium chloride solution with low frequency impedance values more than 1 GOhm cm2 for over 4000 hours of testing. Coatings containing nanocontainers loaded with 2-mercaptobenzothiazole tested with an artificial scribe revealed protection of the AA 2024-T3 substrate in the scribed area, decrease of the anodic delamination in the early hours and decrease number of cathodic dark areas after long immersion time. Overall, epoxy coatings with encapsulated inhibitors can be considered as a promising system for potential replacement of hexavalent chromium treatments on aerospace alloy AA 2024-T3.

Abstract:

Wind turbines are the largest contributor to renewable energy both in Britain and the rest of Europe. With a rise in the installed capacity and an increase in offshore wind energy due to governments green targets by 2020, there has been a large development in new wind turbines for optimized performance. The present thesis deals with the uncertainties in regards to the lightning phenomenon on wind turbines with emphasis on the rotor blades. Rotor blades are the most expensive part to replace in the event of lightning related damage. The research presents results based on lightning data analysis on wind turbines, backed up by finite element analysis testing of wind turbine systems. The final chapters include the testing and improving of lightning protection systems installed on modern day rotor blades. The first part of the thesis deals with the theoretical understanding of the lightning phenomenon and its effect on wind turbine systems. The core work of the research begins with the analysis of lightning data collected over Nysted wind farm and different wind turbines installed over the world. The data analysis helps in identifying the parts of the wind turbine that are at high risk to lightning attachment and related damage. The peak current levels of the lightning strikes seen on the wind turbine are compared with those in modern day lightning standards, and show that historic data in the standards are not an exact match to the real case scenarios. The lightning data analysis also sheds light into the importance of upward initiated lightning, which will become important for large wind turbines, especially in their new offshore environment. A full scale 3D FEA model of a wind turbine, with lightning protection systems installed in its rotor blades, is subjected to electrical stresses to find likely attachment points in regards to upward initiated lightning, and these results are later compared to those found in the data analysis. The second half of the thesis deals with the testing of new materials and prototype blades, to be introduced to reduce their radar cross section. The new materials include a large amount of carbon content which affects the efficiency of the lightning protection system. High voltage and high current tests backed up with finite element analysis have been performed to find how these new materials affect the performance of the lightning protection system. The results indicate that further work needs to be done before these new materials can be integrated into the blade, as they increase the risk of lightning related damage to the blade.

Abstract:

As an important technique for corrosion control in marine environment, Cathodic Protection (CP) should be applied with a full understanding of environmental conditions and a good consideration of current requirements. Early studies on different kinds of steel specimens in the intertidal zone show severe corrosion losses. Nevertheless, there is evidence that CP can work in these regions of a steel structure because electrolyte pathway can remain some time on thin wetted surfaces when tides recede. This research aims to study corrosion activities and their behaviour under the influence of CP in a thin layer of electrolyte as a simulation of the inter-tidal zone. By means of a mechanical vibrating probe, Scanning Vibrating Electrode Technique (SVET) may be used to study local activities at coating defects in a thin electrolyte layer. The effect of CP on the local currents at the defect site was confirmed by SVET and, significantly, the development of calcareous films under these conditions in seawater was also observed. Such films are found to be effective in the absence of cathodic polarisation and only failed after damage. In order to explore the performance of applying CP, a Finite Element (FE) model of electrically connected zinc and steel samples beneath a specific thickness of electrolyte has been created, with full polarisation curves implemented for each metal based on experimental results obtained. The influence of the electrolyte conductivity and the geometry of the electrodes has also been considered. A comparison can then be made between experimental investigation and computational modelling of this corrosion cell. Epoxy-coated and uncoated mild steel samples obtained in the simulated tidal facility were also investigated. The formation of calcareous films was confirmed. Calcareous films were protective under these intermittent wetting conditions. Techniques used to understand the performance include optical observation, Scanning Electron Microscopy (SEM) together with Energy Dispersive X-ray (EDX) and X-ray Diffraction (XRD) analysis.

Full text

Abstract:

The use of electroencephalogram (EEG), an electrophysiological monitoring method for recording the brain activity, for authentication has attracted the interest of researchers for over a decade. In addition to exhibiting qualities of biometric-based authentication, they are revocable, impossible to mimic, and resistant to coercion attacks. However, EEG signals carry a wealth of information about an individual and can reveal private information about the user. This brings significant privacy issues to EEG-based authentication systems as they have access to raw EEG signals. This thesis proposes a privacy-preserving EEG-based authentication system that preserves the privacy of the user by not revealing the raw EEG signals while allowing the system to authenticate the user accurately. In that, perceptual hashing is utilized and instead of raw EEG signals, their perceptually hashed values are used in the authentication process. In addition to describing the authentication process, algorithms to compute the perceptual hash are developed based on two feature extraction techniques. Experimental results show that an authentication system using perceptual hashing can achieve performance comparable to a system that has access to raw EEG signals if enough EEG channels are used in the process. This thesis also presents a security analysis to show that perceptual hashing can prevent information leakage.

Abstract:

This thesis has proposed two types of real time System Integrity Protection Schemes(SIPS) using Emergency Single Machine Equivalent (E-SIME) and Model PredictiveControl (MPC) approaches respectively. They are aiming to resolve the transientstability problems in power systems. Synchronous measurements, fast communicationnetwork and FACTS are deployed in the two SIPSs. The Thyristor Controlled SeriesCompensation (TCSC) is applied as the control action in both SIPSs.In the E-SIME based SIPS, the SIME approach is used to evaluate the transient stabilityof the system and then a decision is made about the control actions needed to stabilizethe system. During emergency conditions, a fast response time is very important andthis requires a security guideline to be used in the decision making process. Theguideline is developed by analyzing offline multiple fault scenarios using an automaticlearning approach. This ensures appropriate control actions can be performed withoutcompromising the response time required on a real system.The MPC based SIPS optimizes the control action at every discrete time instant byselecting the control action that leads to the minimized cost function value. Automaticlearning (AL) is utilized to predict power system dynamics by assuming each controlaction has been taken. Furthermore, a feature selection technique, that chooses themost relevant variables, is used to improve the performance of the AL prediction. Themodel predictive control (MPC) technique is performed every discrete time interval, sothe optimal control action is always selected.Two types of SIPS are tested and verified in the benchmark systems. Simulation resultsshow they can effectively protect the system from loss of synchronism in the aftermathof a large disturbance. This thesis also compares the two SIPSs and concludes thebenefits and shortcomings of each approach.

Abstract:

Corrosion Protection and Microstructure of Dissimilar Materials. A thesis submitted to The University of Manchester for the degree of Doctor of Philosophy by Uyime, Donatus on the 30th of July, 2015.Investigations on the micro- and macro-galvanic corrosion mechanisms in un-coupled AA2024-T3 alloys, AA2024-T3 coupled with mild steel (with and without the influence of cadmium and under varying solution temperatures), dissimilar friction stir welds of AA5083-O and AA6082-T6 alloys and a friction stir welded AA7018 alloy have been carried out. Selected methods of preventing and / or minimising the investigated corrosion phenomena were also investigated. The investigation of the corrosion behaviour of the uncoupled AA2024-T3 alloy revealed that there are two distinct stages of polarization during the galvanostatic polarization of AA2024T3 alloy in de-aerated 3.5% NaCl solution. From the first stage, the relationships between the pitting incubation time, pitting potential and applied current density for AA2024T3 alloy in the de-aerated condition were established. Whilst studying the in situ corrosion phenomena on the uncoupled AA2024-T3 alloy using the scanning vibrating electrode technique (SVET),three distinct stages in the variation of the recorded current density values with time were revealed. Attempts were made to correlate these stages with the corrosion behaviour of the alloy. The study of the galvanic interactions between AA2024-T3 and mild steel revealed that AA2024-T3 is anodic to mild steel at room temperature, but polarity reversal of the couple starts (from a temperature as low as 35 oC upwards) when the couple is introduced into the solution above ambient temperature. Importantly, AA2024-T3 is clearly cathodic to mild steel at 60 oC, although with very low measured galvanic current values. Cadmium coating (at ambient temperature) on the mild steel reduced the galvanic corrosion of the couple by as much as 20 µA/cm2 because of the formation of a CdO/Cd(OH)2 layer on mild steel. In the study of the dissimilar friction stir welds of AA5083-O and AA6082-T6 alloys, it was observed that material flows (pushes but does not mix) more from the advancing side into the retreating side and that the mixture of materials is far from complete. Two welding speeds were compared; the welding speeds have no clear influence on the microhardness, but affected the mixing proportions in the flow arm and in the nugget stem. The faster welding speed resulted in increased susceptibility to corrosion because of the reduced tool rotation per weld length for heat generation and the mixing of materials. The heat affected zones of both alloys and the transition regions between the AA5083-O alloy and the AA6082-T6 alloy rich zones have been identified to be the regions that are most susceptible to corrosion. Anodizing the weld in order to minimise corrosion showed that the AA5083-O alloy rich zones materials, in the weld, oxidizes more during anodizing compared with the AA6082-T6 alloy rich zones. Sputtering deposition prior to anodizing, promotes the formation of a uniform oxide film across the entire weld zones and prevents the boundary dissolution that occurs when the dissimilar weld of AA5083-O and AA6082-T6 alloys is anodized in 4 M H2SO4 solution at 15 V at ambient temperature. The investigation of the corrosion susceptible regions in friction stir welded AA7018 alloy, which was based on the use of ISO 11846 immersion test and the potentiodynamic polarization technique in naturally aerated 3.5 % NaCl solution, revealed intergranular, crystallographic and second phase particle influenced mode of attack. The heat affected zone was found to be the most susceptible to corrosion.

Abstract:

Voltage-Sourced Converter High Voltage Direct Current (VSC-HVDC) transmission technology has received great interest and experienced rapid development worldwide because of its compact size, ability to connect two asynchronous AC systems and ability to connect to weak AC grids. It is expected that VSC-HVDC will play a significant role in future power transmission networks. Multi-Terminal Direct Current (MTDC) networks are even being established based on VSC-HVDC and these have great potential to support conventional AC transmission networks. However, such DC networks are vulnerable to any DC side short-circuit fault. DC protection issues must be tackled to enable the development of MTDC networks. This thesis conducts some of the underpinning research for such DC protection studies. As a first step to conduct the protection study, a detailed four-terminal VSC-HVDC system is developed in PSCAD/EMTDC, which consists of both two-level converters and MMC devices. Based on this high fidelity four-terminal system model, a thorough analysis is conducted for the two-level converter and the MMC systems under different fault scenarios. Based on this, a basic understanding of the converter systems' natural responses to these fault scenarios is obtained. Apart from using a DC circuit breaker to isolate a DC fault, there may be other devices which could potentially be used for DC protection. After the fault analysis, a study is conducted to search for any other DC protection equipment which could help the DC breaker isolate a DC fault. Different types of fault current limiters (FCLs) are reviewed and compared. It is found that the resistive type superconducting FCL (SCFCL) has the potential to be usefully employed for DC protection. Next, a DC fault detection and location strategy study is performed. This thesis conducts a detailed study of different DC fault detection and location strategies using a much higher fidelity model than previous studies. After reviewing different fault detection methodologies, it is found that wavelet transforms presently might be the best option for DC protection. The continuous wavelet transform (CWT) is then extensively tested under different DC faults and transient scenarios to prove its robustness, as this method has not been extensively studied in the previous literature. In the end, by using the CWT and placing the SCFCLs in series with DC circuit breakers, the performance of the SCFCLs under a DC side pole-to-pole fault is examined. This study shows that the SCFCL can help reduce the fault current seen by a DC breaker. In the end, a DC system fault recovery study is performed. Different methods are proposed and studied to examine the impact they have on the converter system's DC fault recovery process. A novel bump-less control is proposed to help the system achieve a good fault recovery response.

Abstract:

A steganographic method was developed based on the temporal redundancies present in digital video streams, these redundancies are utilised by the H.264 encoding standard to reduce the bandwidth requirements of a digital video stream while maintaining content quality. The temporal redundancies are used to steganographically embed unique binary data within the digital video stream, this results in a unique embedding strategy within each video stream while also utilising areas that reduce the potential data loss experienced during the H.264 encoding process. The effectivness of the developed steganographic method is measured using the common steganographic metrics of Payload Capacity, Embedded Data Robustness and Media Impact. The results illustrate that the compensation of mutative factors in the embedding process using temporal redundancies result in a more robust method of data embedding within digital video encoded using H.264.

Abstract:

Recent interest in environmentally friendly alternatives to chromate-based corrosion inhibitors has led to the development of a range of novel coating formulations. The work described in this thesis has been aimed at investigating the mechanism of self-healing and active corrosion protection of the new coatings by searching for active components that have migrated from the coating to a controlled defect. The use of glow discharge optical emission spectroscopy (GDOES) has been investigated as a tool for both the generation of a reproducible controlled defect and for elemental depth profiling of the coatings and corroded substrates. Conclusions drawn from the elemental depth profiles have been validated by a range of characterisation techniques including optical microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX) and electrochemical techniques. The work has focused particularly on a comparison of hybrid coatings doped with inhibitors encapsulated in nano-containers, as compared with the direct addition of inhibitor species to the coating matrix. The work also investigates the effects of inhibitor addition to sol-gel coatings or primer systems or both, highlighting possible synergistic effects of mixed inhibitor systems (for example, sol-gel coating doped with strontium aluminium polyphosphate (SAPP)) supporting primers doped with benzotriazol (BZT) or mercaptobenzothiazol (MBT). The various coatings have also been studied in the absence of inhibitor species to assess the effectiveness of the coatings as barriers between the substrate and the corrosive environment. This aspect of the study has highlighted minor inhibitive effects of some of the reagents used in the coating formulations and a major inhibitive effect of the nano-containers. The work therefore concludes with recommendations for a possible coating formulation combining the most beneficial elements of the various coatings investigated.

Abstract:

This thesis investigates whether English law ought to be further developed to provide fuller protection for the privacy of the corporation. As an essential preliminary step, the thesis first explores the concept of privacy in general – privacy interests, definitions of privacy, rationales of privacy; and then proceeds to formulate a concept of privacy for the corporation. The thesis advances to consider the level of protection of the privacy of the corporation in English law, and finds that only a limited level of protection is provided – in broadcasting matters – by the Broadcasting Act 1996. The thesis then proceeds to critically examine whether the extended action for breach of confidence which protects an individual's privacy can and ought to be further developed to provide protection for the corporation’s privacy, and argues that the corporation’s privacy can and ought to be so developed. The thesis also investigates whether, in the alternative, the corporation’s privacy would be more suitably protected if it were developed as a property right under Article 1 of Protocol 1 ECHR, and finds that Article 1 of Protocol 1 would not suitably protect the corporation’s privacy. Instead, the thesis upholds the extended action for breach of confidence as a more natural and suitable home for the protection of the privacy of the corporation in English law. The thesis concludes with recommendations on the structural framework for the proposed protection of the corporation’s privacy under the extended action for breach of confidence. This research is undertaken primarily through doctrinal analysis; it analyses English Courts’ jurisprudence, the European Court of Human Rights jurisprudence, as well as the jurisprudence of the Court of Justice of the European Union where it concerns the administration of Article 8 ECHR. Theoretical arguments are also engaged in when it comes to defining and justifying the protection of the corporation’s privacy.

Abstract:

China has put considerable emphasis on protecting intellectual property (IP) rights since it implemented ‘Reform and Opening-Up’ policy in the late 1970s. The nation has actively participated in communication and cooperation with its trading partners and international society in IP region. In particular, since its accession to the Paris Convention for the Protection of Industrial Property (Paris Convention) in 1985, China has reformed its socialist legal system to meet international obligations. This trend continued with China’s entry to the Agreement on Trade-Related Aspects of Intellectual Property (TRIPS) under the World Trade Organization (WTO) in late 2001. A well-known trademark is a trademark well known by the relevant public. Compared to a common trademark, it will be given higher level of protection against infringements. A well-established well-known trademark legal framework can considerably protect interests of owners of domestic and foreign well-known trademarks. China begun to offer such protection since the 1980s. During the pre-WTO period, it granted well-known status determination on an ad-hoc basis under a ‘Sole-Track’ model which was solely led by administrative authorities. This model has been considered to be weak and offered no systematic protection to well-known trademark holders. China’s admission to the WTO in 2001 pushed the country to create a ‘Dual-Track’ model which incorporates judicial and administrative authorities and to amend its IP laws in compliance with the international norms. Since then, the situation of well-known trademark protection has been considerably improved, although some problems remained. There is, however, widespread criticism in the US government and from some scholars that the IP laws in China governing well-known trademarks are inadequate. However, this is not necessarily accurate, as it is based not on comprehensive legal analysis but on the data mainly collected from interested parties of the US side, whether they are companies or government officials, or a fragment of cases. This thesis adopted doctrinal legal research method to demonstrate and evaluate some substantial legal principles, concepts, rules and policy concerning well-known trademark recognition and protection in China over the past three decades (1985 – 2015). It challenged that criticism by raising four questions and exploring their answers. The legal analysis in this thesis showed that since the 2000s, China has protected well-known trademarks more effectively than before. In conclusion, although some problems remain to be solved, the criticism above should be rejected. Meanwhile, this thesis also offered suggestions of further development, highlighted the need for the competent authorities to continue to reform the laws and policy, and strengthen their enforcement in order to tackle unsolved problems.

Abstract:

The contents of this thesis describe the results of an investigation into the means by which computer aided design (CAD) may be applied to the protection systems of electrical drives, removing much of the repetitive procedures presently used in determining relay settings. To further this aim, a series of algorithms have been devised which allow exploitation of the concept. The areas chosen for demonstration are, direct-on-line started induction motors and transformer fed variable speed drives. In both cases "standard settings' cannot be implemented as the field of application varies enormously. The text discusses an algorithm which utilises several databases containing motor, fuse and cable parameters. Chapter three uses a program derived from this algorithm which allows data to be extracted from the databases and manipulated in order to determine the optimum circuit components. Subsequent chapters examine the implementation of two types of motor protection relay and discusses the algorithms used in modelling them. The text is supported by applications which demonstrate the effectiveness of the derived programs. Chapter six discusses in depth the application of overcurrent relays for the protection of transformers used on variable speed drive installations. The possibility of using overcurrent elements in two or three phases is examined together with the attendant difficulties which may arise. The algorithms are further expanded to incorporate applications which involve the protection of multi-transformer installations supplied from a common point.
