Westner, Isabelle. "Att mäta utsatthet för mobbning på arbetsplatsen : Svensk översättning och validering av skala." Thesis, Södertörns högskola, Psykologi, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:sh:diva-33154.
Full textAbstract:
Mobbning på arbetsplatsen kan definieras som återkommande psykiska kränkningar, ofta riktade mot en person från en eller flera kolleger. Dessa handlingar sker frekvent och över en längre period. Konsekvenser till följd av mobbning är psykiska, psykosomatiska och sociala besvär. Olika mätmetoder kan ge upphov till skilda resultat och frekvenser för förekomsten av mobbning på arbetsplatsen. Ett korrekt mått på utsatthet för mobbning är viktigt för samhälle och organisation för att kunna anpassa resurser för att hantera problemet. Ett internationellt ofta använt verktyg för att mäta utsatthet för mobbning på arbetsplatsen är Negative Acts Questionnaire Revised (NAQ-R), som har dokumenterad validitet och visat på goda psykometriska egenskaper. Syftet med den aktuella studien var att översatta och validera NAQ-R till svenska samt att jämföra resultaten med tidigare valideringar. Ett urval på 133 personer besvarade en webbenkät med NAQ-R, skalor för arbetsbelastning, rollkonflikter samt hälsa. Ett antal analyser genomfördes för att testa reliabilitet, begreppsvaliditet, samband med variabler som tidigare visat sig ha ett samband med mobbning, samt faktorstruktur. Resultatet visade hög intern konsistens, begreppsvaliditet samt starka samband med arbetsbelastning och rollkonflikter vilka är faktorer som i tidigare forskning visats kunna leda till mobbning på arbetsplatsen. Resultatet visar också ett starkt samband med ohälsa som en konsekvens av mobbning vilket går i linje med tidigare forskning. Sammantaget tyder aktuell studie på att den svenska översättningen av NAQ-R (NAQ-R-S) är ett tillförlitligt och trovärdigt instrument för att mäta mobbning på arbetsplatsen.

Obeng, Samuel. "Design, Synthesis, and Biological Screening of Selective Mu Opioid Receptor Ligands as Potential Treatments for Opioid Addiction." VCU Scholars Compass, 2017. http://scholarscompass.vcu.edu/etd/4771.
Full textAbstract:
Today, more Americans die each year because of drug overdoses than are killed in motor vehicle accidents. In fact, in 2015, more than 33,000 individuals died due to an overdose of heroin or prescription opioids. Sadly, 40-60 % of patients on current opioid addiction treatment medications relapse. Studies have shown that the addiction/abuse liability of opioids are abolished in mu opioid receptor (MOR) knock-out mice; this indicates that the addiction and abuse liability of opioids are mainly mediated through MOR. Utilizing the “message-address concept”, the our laboratory reported a novel non-peptide, reversible MOR selective ligand 17-cyclopropylmethyl-3,14β-dihydroxy-4,5α-epoxy-6α (isoquinoline-3-carboxamido)morphinan (NAQ). Molecular modeling and mutagenesis studies revealed that the selectivity of NAQ for MOR is because of the π-π stacking of the isoquinoline ring of NAQ with W318.
Therefore, other heterocyclic ring systems were explored to obtain a diverse library of compounds with similar or different molecular interactions and pharmacologic characteristics as NAQ. The newly designed compounds were indole analogs of 6α/β-naltrexamine. The compounds were synthesized and the affinity and selectivity for MOR determined using the radioligand binding assay while the functional activity at MOR was determined using the [35S]GTPγS binding assay. The indole analog of 6α-naltrexamine substituted at position 7 (compound 6) was found to be very potent and had the lowest efficacy in the [35S]GTPγS functional assay while the indole analog of 6β-naltrexamine substituted at position 2 (compound 10) was identified as a MOR agonist and had the greatest efficacy. In vivo studies were conducted using the warm-water immersion assay to find whether the synthesized compounds had antinociceptive effects and/or blocked the antinociceptive effects of morphine. Not surprisingly, compound 10 was identified as an opioid agonist while compound 6 almost completely blocked morphine’s antinociceptive effects. The opioid antagonist effect of compound 6 was found to be dose dependent with an AD50 of 2.39 mg/kg (0.46-12.47). An opioid withdrawal assay was conducted on compound 6 using morphine-pelleted mice. Compound 6 produced significantly less withdrawal symptoms at 50 mg/kg than naltrexone at 1 mg/kg. Therefore, compound 6 has the potential to be used in opioid addiction and withdrawal treatment.

Previous issue date: 2011-12-16Porcelains are manufactured from natural raw material, in which are inclined the presence of diverse impurities. The presence of impurity can modify significantly the various characteristics of the porcelain, mainly the mechanical characteristics. Then, the understanding about the mechanism of actuation of these impurities is fundamentally important to reach the desired characteristics. In this dissertation, it was studied the effects of the addition of oxide generators additives on the microstructural development and on the properties of aluminous porcelain, siliceous and aluminous-siliceous, aiming to understand the actuation mechanism of these additives and what is their influence with the variation of ceramic mass composition. It had been chosen three types of porcelain: Porcelain of Alumina-Feldspar-Kaolin system, Silica-Feldspar-Kaolin and Alumina-Silica-Feldspar-Kaolin. In each composition it was added the additives, which were mixed wet in balls mill, and dry in stove. The resulting powders from these mixtures were pressed and sintered. The sintered porcelains were characterized by apparent density measurement, water absorption, linear contraction, porosity percentage, X-ray diffraction, electronic microscopy scan, EDS microanalyses and rupture module by three points flexion. In the aluminous, siliceous and the aluminous-siliceous porcelains compositions, the presence of additives reduced the values of the modules of rupture, nevertheless for the major of the samples added to these additives, the sintering temperature was reduced. It was verified that in every composition and with every additive used, actuate directly on the formation of the liquid stage, and it is this stage that during the sintering, modifies the other present stage and then, modify the microstructure and consequently the mechanical characteristics of the porcelain.
As porcelanas são fabricadas a partir de matérias primas naturais, as quais estão sujeitas a presença de diversas impurezas. A presença de impurezas pode alterar de maneira significativa as diversas propriedades das porcelanas, principalmente as propriedades mecânicas. Com isso o entendimento do mecanismo de atuação destas impurezas é de fundamental importância para se atingir as propriedades desejadas. Nesta dissertação foram estudados os efeitos da adição de aditivos geradores de óxidos no desenvolvimento microestrutural e nas propriedades de porcelanas aluminosas, silicosas e aluminosas silicosas, com o objetivo de se entender o mecanismo de atuação destes aditivos e qual a influência destes com a variação de composição da massa cerâmica. Foram escolhidos três tipos de porcelanas: porcelana de sistemas Alumina-Feldspato-Caulim, Sílica-Feldspato-Caulim e Alumina-Sílica-Feldspato-Caulim. A cada composição foram adicionados os aditivos, os quais foram misturados a úmido em moinho de bolas e secos em estufa. Os pós resultantes destas misturas foram prensados e sinterizados. As porcelanas sinterizadas foram caracterizadas através de medidas de densidade aparente, absorção de água, retração linear, porcentagem de porosidade, difração de raios X, microscopia eletrônica de varredura, microanálise via EDS e módulo de ruptura por flexão em três pontos. Nas composições de porcelanas aluminosas, silicosas e alumino-silicosas, a presença de aditivos diminuiu os valores do módulo de ruptura. Porém para a maioria das amostras dopadas com estes aditivos, a temperatura de sinterização diminuiu. Foi verificado que em todas as composições e com todos os aditivos utilizados, atuam diretamente na formação da fase líquida e é esta fase que durante a sinterização modifica as demais fases presentes e assim, altera a microestrutura e consequentemente afeta as propriedades mecânicas da porcelana.

Resumo: Esta pesquisa propõe um estudo das obras das fotógrafas norteamericanas Cindy Sherman e Nan Goldin, mais especificamente dos seus trabalhos Untitled Film Stills e The Ballad of Sexual Dependency, respectivamente. Ambas são artistas de extrema importância para a arte fotográfica contemporânea, possuem praticamente a mesma idade, vivem e trabalham na mesma cidade, escolheram a fotografia como forma de expressão, mas, apesar destas e outras semelhanças, possuem uma produção bem diferente a principio. Enquanto Sherman constrói ficções Goldin registra a realidade a sua volta. Sherman é uma artista que cria cenas, universos, se inserindo dentro destes através de personagens que ela mesma incorpora. A artista cria mundos de representações que abordam toda a cultura, em especial a feminina. Já Goldin trabalha de forma mais instantânea, registra o mundo ao seu redor, guardando momentos, às vezes mais banais, às vezes mais íntimos, dos que a rodeiam e de sua própria vida, tornando público o que antes era privado. Mesmo com processos de criação tão distintos, e com motivações e resultados diferentes, o trabalho das duas fotógrafas pode ser relacionado pela temática do universo feminino que ambos abordam, onde nos é apresentado a vida privada de várias mulheres, sejam elas reais ou ficcionais. Assim, essas produções são postas lado a lado, evidenciando que caminhos diferentes podem levar a um mesmo lugar
Abstract: This research proposes a study of the works of American photographers Cindy Sherman and Nan Goldin, specifically their work "Untitled Film Stills" and "The Ballad of Sexual Dependency", respectively. Both artists are extremely important for contemporary photographic art, have practically the same age, live and work in the same city, chose photography as a form of expression, but, spite of these and other similarities, have a production very different at first. While Sherman builds fictions Goldin registers reality around her. Sherman is an artist who creates scenes, universes, inserting themselves inside of those through personages which she herself incorporates. The artist creates worlds of representations addressing the whole culture, particularly of women. Already Goldin works more instantaneous, registers the world around them, keeping moments, sometimes more banal, sometimes more intimates, of those around her and of your own life, making public what was once private. Even with creative processes so distinct and different motivations and outcomes, the work of the two photographers can be related by the theme of feminine universe they both deal with, where is presented to us the private lives of several women, whether real or fictional. Thus, these productions are placed side by side, showing that different paths could lead to the same place

Full textAbstract:
As células trofoblásticas provenientes de cones ectoplacentários na fase de pós-implantação expressam as subunidades do complexo NAD(P)H-oxidase de membrana p22-phox, gp91-phox, p47-phox, p40-phox, p67-phox e Rac1 previamente descritas em fagócitos e envolvidas com a atividade fagocitária destas células. Ocorre modulação da expressão das subunidades do complexo enzimático NAD(P)H-oxidase sob o estímulo com PMA, agente capaz de fosforilar a subunidade p47-phox e ativar esta enzima em fagócitos profissionais. Nossos ensaios experimentais indicam que as células trofoblásticas são capazes de gerar espécies reativas de oxigênio dependente da atividade do complexo NAD(P)H-oxidase de membrana de baixa intensidade quando não estimuladas e de forma muito mais intensa quando estimuladas pelo PMA. As características de expressão e atividade do complexo enzimático NAD(P)H-oxidase de membrana encontradas neste estudo sugerem que esta enzima é semelhante a encontrada em outros fagócitos e, desta forma possa talvez estar também envolvida com processos de defesa da interface materno-fetal.In macrophages and neutrophils, the activation of the phagocytosis is defined by the acquisition of competence for microbicide, tumoricide and cytolytic functions resultant of generation and release of oxygen reactive species, besides the phagocytic process per se. Like these phagocytes, trophoblast cells in many species are also phagocytic. This cellular population involves completely the embryo and exhibits different and specific characteristics along the gestation. In rodents and primates, these cells are strategically positioned between maternal and fetal circulation and exhibit invasive and phagocytic activity, respectively responsible for anchorage of the embryo into the endometrium and uptake of an adequate nutritional supply for the embryo development. In rodents, these activities present a maximum degree during the implantation period, gradually declining, as the placenta develops. In the presence of strange particles at the maternal-placental interface, however, this process can be reactivated and, in this case, may be related to defense\'s mechanisms. Previous studies performed in our laboratory showed the potential of the trophoblast in producing and releasing reactive species of oxygen/nitrogen, in a very similar manner to that observed in macrophages and neutrophils. The production of such molecules is associated to different enzymes, but the localization of hydrogen peroxide on trophoblast cell surface has suggested a NAD(P)H-oxidase activity. NAD(P)H-oxidase is formed by the cytochrome b558 associated to the cellular membrane (subunits p22-phox + gp91-phox), the cytosolic subunits p47-phox, p67-phox and p40phox and, the GTPases Rac1 and Rac2 in an electron generator system that uses NADH or NADPH as substratum. Once activated, the enzymatic complex is responsible for the electron inflow to the molecular oxygen, yields superoxide anion. Thus, based on the literature and results previously obtained by our group, this study analyzed the protein and gene expression of the NAD(P)H-oxidase complex subunits respectively by immunolocalization and Westernblotting and rt-PCR, in the mouse trophoblast stimulated with PMA. Rt-PCR semi-quantitative analyses showed increase expression of the subunits p22-phox, gp91-phox, p47-phox, p67-phox, p40phox and Rac1 in PMA-treated in comparison with non treated ectoplacental cones. The expression of the subunits gp91-phox, p47-phox and p67-phox were confirmed by Western blotting and, like gene expression also increased in the presence of PMA. These subunits were mostly located in the trophoblast giant cell population, associated to the phagocytic process at the maternal-placental interface. Increased expression of such subunits may be related to an increase in the NAD(P)H-oxidase activity. To analyze this possibility and to determine the role played by NAD(P)H-oxidase activity in the reactive oxygen species produced by trophoblast cells, cellular assays were performed using the oxyethidium fluorescence, a product of dihydroethidium oxidation by superoxide anion. Thus, under PMA stimulus and antimycin A that blocks the mitochondrial NAD(P)H-oxidase activity and, apocynin and allopurinol, respectively blocking the membrane NAD(P)H-oxidase and xhantine oxidase and, still, using specific superoxide and hydrogen peroxide scavengers (superoxide dismutase enzyme and catalase) we showed the generation of reactive species of oxygen-NAD(P)H-oxidase dependent by trophoblast cells, mostly when stimulated. These results come to add important information about the potential of the trophoblast in producing reactive species at the maternal-fetal interface and, open a new investigation interest on the NADPH-oxidase regulatory processes and its involvement in defense functions of the embryo in both healthy and pathological processes that can determine the failure of the gestation.

Full textAbstract:
The main objective for this degree project was to analyze the Endpoint Security Solutions developed by Cisco, Microsoft and a third minor company solution represented by InfoExpress. The different solutions proposed are Cisco Network Admission Control, Microsoft Network Access Protection and InfoExpress CyberGatekeeper. An explanation of each solution functioning is proposed as well as an analysis of the differences between those solutions. This thesis work also proposes a tutorial for the installation of Cisco Network Admission Control for an easier implementation. The research was done by reading articles on the internet and by experimenting the Cisco Network Admission Control solution. My background knowledge about Cisco routing and ACL was also used. Based on the actual analysis done in this thesis, a conclusion was drawn that all existing solutions are not yet ready for large-scale use in corporate networks. Moreover all solutions are proprietary and incompatible. The future possible standard for Endpoint solution might be driven by Cisco and Microsoft and a rude competition begins between those two giants.

Análise da interferência dos níveis hierárquicos na eficácia da comunicação interna da Telesc, enfatizando as conseqüências de um processo comunicativo defeituoso na implementação de ações e no alcance dos objetivos organizacionais. Analisa as causas da presença de uma rígida estrutura hierárquica, que costuma trazer sérios prejuízos à organização, através de um estudo sobre a formação do Estado burocrático brasileiro. Ressalta que a prática desenfreada de um clientelismo na administração pública do país, e também na Telesc, tem se caracterizado como um dos principais responsáveis pela ineficácia dos serviços públicos e pelo surgimento de vários distúrbios organizacionais, como ausência de critérios mais adequados para a seleção de chefes e gerentes, nepotismo e desmotivação do corpo funcional.

A substituição da fonte de calor convencional por fontes de radiação de micro-ondas vem sendo bastante explorada na área de síntese de sólidos inorgânicos devido ao seu eficaz mecanismo de entrega de energia que proporciona rapidez no processo de síntese além de gerar materiais com maior pureza de fase. Neste contexto, o presente trabalho visou a otimização das sínteses das zeólitas NaA e NaX utilizando radiação de micro-ondas e a caracterização utilizando as técnicas de DRX (Difração de Raios-X), MEV (Microscopia eletrônica de varredura) e EDS (Energy-dispersive X-Ray Spectrocopy). As zeólitas foram sintetizadas e caracterizadas visando a posterior aplicação como agentes hemostáticos coagulantes. Os experimentos mostraram que a zeólita NaA obtida utilizando radiação de micro-ondas durante 30 minutos possui as mesmas características da zeólita NaA sintetizada utilizando aquecimento convencional por 48 horas, indicando que com a utilização da radiação foi possível alcançar uma redução de 98,96% no tempo de síntese. A aplicação de aquecimento de micro-ondas na síntese da zeólita NaX também provou decréscimo no tempo de síntese quando comparado ao aquecimento convencional, entretanto os dados de microscopia eletrônica revelaram que a zeólita sintetizada pelo aquecimento de micro-ondas estavam aglomeradas. A fim de tornar o coloide mais estável, foi feita a estabilização estérica dessas zeólitas através da esterificação dos grupos silanóis presentes na superfície das mesmas utilizando 1-propanol e 1-butanol. Os dados MEV mostraram que a modificação foi eficiente e que a dispersão foi estabilizada após o tratamento. Em relação ao potencial das zeólitas como agentes hemostáticos coagulantes, os dados de tromboelastografia mostraram que as zeólitas NaA e NaX provocaram diminuição no tempo necessário para a formação e crescimento do coágulo porém, dentre todas as zeólitas avaliadas, a zeólita NaX sintetizada por aquecimento convencional se destacou como agente hemostático apresentando uma redução de 6 minutos no tempo de formação do coágulo.
Conventional heat source has been substituted by microwave heat source in many chemical reactions including inorganic solids syntheses, since the microwave heat source can accelerate the energy delivery. Because of that, it is possible to obtain syntheses in a shorter time and materials obtained have a higher purity phases. Zeolites were synthesized and characterized aiming to zeolites hemostatic agents application. In this context, this work aimed to synthesize NaA and NaX zeolites employing microwave radiation and to characterize materials obtained using XRD (X-Ray Diffraction), SEM(Scanning Electron Microscopy) and EDS (Energy-dispersive X-Ray Spectrocopy) techniques. NaA zeolite obtained by microwave radiation after 30 minutes showed the same characteristics of NaA zeolite obtained by conventional heat after 48 hours. In other words, the substitution of the heat source reduced 98,96% the synthesis time. Related to NaX zeolite, microwave radiation also reduced the synthesis time, however SEM and EDS data showed some differences between NaX obtained by conventional and NaX obtained by microwave heating. It was also observed by SEM that the colloidal system of NaX obtained by microwave radiation has agglomerated. In order to stabilize sterically the colloid, NaX surface was functionalized by silanols groups esterification using 1-propanol and 1-butanol alcohols. SEM data showed that steric stabilization was successful. Regarding the potential of the zeolites as hemostatic coagulating agents, thromboelastography data showed that NaA and NaX zeolites caused decrease in time required for clot formation and growth. However, among all the zeolites evaluated, NaX zeolite synthesized by conventional heating had better results as a hemostatic agent showing a reduction of 6 minutes in clot formation time.

Resumo: A substituição da fonte de calor convencional por fontes de radiação de micro-ondas vem sendo bastante explorada na área de síntese de sólidos inorgânicos devido ao seu eficaz mecanismo de entrega de energia que proporciona rapidez no processo de síntese além de gerar materiais com maior pureza de fase. Neste contexto, o presente trabalho visou a otimização das sínteses das zeólitas NaA e NaX utilizando radiação de micro-ondas e a caracterização utilizando as técnicas de DRX (Difração de Raios-X), MEV (Microscopia eletrônica de varredura) e EDS (Energy-dispersive X-Ray Spectrocopy). As zeólitas foram sintetizadas e caracterizadas visando a posterior aplicação como agentes hemostáticos coagulantes. Os experimentos mostraram que a zeólita NaA obtida utilizando radiação de micro-ondas durante 30 minutos possui as mesmas características da zeólita NaA sintetizada utilizando aquecimento convencional por 48 horas, indicando que com a utilização da radiação foi possível alcançar uma redução de 98,96% no tempo de síntese. A aplicação de aquecimento de micro-ondas na síntese da zeólita NaX também provou decréscimo no tempo de síntese quando comparado ao aquecimento convencional, entretanto os dados de microscopia eletrônica revelaram que a zeólita sintetizada pelo aquecimento de micro-ondas estavam aglomeradas. A fim de tornar o coloide mais estável, foi feita a estabilização estérica dessas zeólitas através da esterificação dos grupos silanóis presentes na superfície das mesmas...

Entre os modelos de fixadores internos há um sistema denominado S.P.S. Free-Block, cuja placa possui um anel trava que possibilita o bloqueio do parafuso em angulações variadas. Visto os poucos estudos biomecânicos com o sistema, o presente trabalho avaliou a influência da orientação do parafuso bloqueado na resistência da montagem. Foram usados cilíndricos sintéticos, nos quais foram promovidas falhas segmentares de 10 mm. As placas de aço com 7 furos (2 DCP e 5 bloqueados) foram montadas de acordo com a posição dos parafusos nos orifícios bloqueados: Grupo 1 – parafusos monocorticais posicionados em 90º, Grupo 2 – parafusos monocorticais posicionados de forma inclinada em 20º. Os parafusos dos orifícios DCP foram aplicados rotineiramente em posição neutra e de maneira bicortical. Na região da falha segmentar o orifício do parafuso bloqueado situado no centro da placa entre os DCP foi mantido livre. Em cada grupo, seis montagens foram testadas até a falência, três em flexão em quatro pontos e três em compressão axial, para determinar as cargas de teste. Posteriormente, em cada grupo, 14 montagens foram testadas até a falência em fadiga, sete em flexão e sete em compressão. Pela análise estatística não houve diferença na rigidez das construções entre os Grupos 1 e 2, tanto nos testes estáticos como nos de fadiga. Conclui-se assim que, em modelo de falha segmentar, o posicionamento do parafuso monocortical bloqueado não influenciou a resistência mecânica das montagens
Among the locked internal fixators is one denominated S.P.S. Free-Block that was designed with a locking ring that allows the screw to be locked and positioned obliquely. Due to the paucity of biomechanical studies on this system, the present work aimed to evaluate the influence of locked screw orientation on the resistance of the S.P.S. Free-Block plate. Non-osteoporotic synthetic bone cylinders with 10 mm fracture gap were used. Seven-hole 3.5 mm stainless steel plates (two DCP holes and five locked holes) were assembled according to the orientation of the blocked screws: monocortical screws positioned at 90º to the long axis of the cylinder (G1), and monocortical screws positioned at 20º to its cylinder long axis (G2). In both groups, DCP hole screws were positioned bicortically and neutrally. In the region of the fracture gap, the locked screw hole at the plate’s center was unfilled. For each group, six specimens were tested until failure, three in bending and three in compression, to determine the loads for fatigue testing. Subsequently, for each group, 14 specimens were tested for failure, seven by bending and seven in compression. No significant failure differences were observed between Groups 1 and 2 under static-loading or fatigue test. In a fracture gap model the orientation of the locked monocortical screws did not show any influence on the mechanical performance of the S.P.S. Free-Block

Objectives: To analyze the effect of NaF and TiF4 varnishes on nanohardness (N) and elastic modulus (E) of enamel surface after very short exposure time to simulation of drinking a can of soft drink; and evaluate the thickness and topography of protective layer formed, by atomic force microscopy (AFM). Methods: Thirty blocks of human enamel (4x4 mm) were divided into 3 groups (n=10): control, NaF varnish and TiF4 varnish. The specimens remained in artificial saliva for 24h, and the varnishes were applied only once. After 6h, specimens were submitted to erosive challenge (10 cycles: 5s in cola drink/5s in artificial saliva). The thickness of protective layer formed and the surface topography were evaluated by optical microscope and AFM. The data were subjected to Two-Way ANOVA, Tukey and Student s-t (α=0.05). Results: The values shown for N and E (GPa) before and after erosive challenge differed statistically, only for control and TiF4 groups. After the erosive challenge, NaF group showed statistically higher values for N and E than those found for control and TiF4 groups. However, the thickness and depth of indentation values showed that N and E values found for TiF4 group were related to the protective layer formed. By AFM, both varnishes showed globular protective layer formation, and the thickness of layer was significantly higher for TiF4 than NaF group. Conclusions: NaF varnish was able to protect the nanomechanical properties of enamel after short erosive challenge, and TiF4 varnish showed a thick and homogeneous protective layer formation with nanomechanical properties. Keywords: tooth erosion; elastic modulus; fluorides; microscopy, atomic force
Objetivos: Analisar o efeito dos vernizes de NaF e TiF4 na nanodureza (N) e módulo de elasticidade (E) da superfície do esmalte após um curto tempo de exposição a bebida a base de cola, simulando a ingestão de uma lata de refrigerante, e também avaliar a espessura e topografia da camada protetora formada, por meio de microscópio de força atômica (AFM). Métodos: Trinta blocos de esmalte humano (4x4 mm) foram divididos em 3 grupos (n = 10): controle (sem verniz), verniz de NaF e verniz de TiF4. As amostras permaneceram em saliva artificial durante 24 horas, e os vernizes foram aplicados apenas uma vez. Após 6h os espécimes foram submetidos a desafio erosivo (10 ciclos: 5s em bebida a base de cola/5s em saliva artificial). A espessura da camada protetora formada e a topografia da superfície foram avaliadas por microscopia óptica e AFM. Os dados foram submetidos à ANOVA Two-Way, Tukey e T- Student (α = 0,05). Resultados: Houve diferença estatística dos valores de N e E (GPa), antes e após o desafio erosivo, apenas para os grupos controle e TiF4. Após o desafio erosivo o grupo NaF mostrou estatisticamente maiores valores de N e E que os grupos controle e TiF4. No entanto, os valores da espessura e profundidade da indentação mostraram que os valores encontrados de N e E para o grupo TiF4 estavam relacionados com a camada protetora formada e não com o esmalte erodido. Ambos os vernizes mostraram, por meio de AFM, a formação de uma camada protetora globular, e a espessura da camada formada foi significativamente maior para o grupo TiF4 que NaF. O verniz de NaF foi capaz de proteger as propriedades nanomecânicas de esmalte após curto desafio erosivo e o verniz de TiF4 apresentou formação de camada protetora espessa e homogênea com propriedades nanomecânicas . Conclusões: O verniz de NaF foi capaz de proteger as propriedades nanomecânicas de esmalte após curto desafio erosivo e o verniz de TiF4 apresentou formação de camada protetora espessa e homogênea com propriedades nanomecânicas.

Den här rapporten beskriver en experimentell studie av Microsoft Network Protection (NAP) och är ämnad för att utvärdera hur mogen tekniken är för att implementeras i en aktiv nätverksmiljö. För att göra studien tog vi hjälp av gymnasieskolan John Bauer i Kalmar. Tester har utförts med DHCP-framtvingning och 802. 1x-framtvingning, dessa är två av NAPs fyra olika framtvingande funktioner. En mindre analys av skolans switchkonfigurationer och interna säkerhet har även gjorts på John Bauers begäran. Testerna har visat att DHCP-framtvingning är en bra och enkel lösning för John Bauers trådade klienter. NAP-funktionen 802. 1x- framtvingning var en större utmaning dock, och blev inte lyckad. Utbudet av information om NAP är än för knapphändig och vi anser därför att inte bara 802.1x framtvingning inte är redo för implementation, utan även framtvingning med DHCP.

Cette étude concerne l’architecture récente du quartier Bui Thi Xuan à Hanoi, au Vietnam. Depuis l’instauration de la politique de libéralisation économique du doi moi en 1986, le secteur privé vietnamien participe activement aux domaines de la construction et de la rénovation. La recherche examine particulièrement les bâtiments en béton qui sont érigés en hauteur sur des parcelles étroites et profondes, et souvent rénovés tôt après leur construction. La rapidité et la fréquence des interventions font douter de la qualité des édifices à long terme. Le travail vise à évaluer comment ces bâtiments peuvent être adaptés pour répondre aux contraintes de densification urbaine actuelles et projetées. Par une analyse systémique, l’étude discutera de la viabilité des interventions en fonction des critères d’adaptabilité et de qualité environnementale. La présentation des rénovations récentes permettra ensuite de déduire le processus évolutif réel des édifices. Pour conclure, le travail démontrera que ce type architectural, dans son état actuel, détient un potentiel d’adaptation qui est toutefois sous-exploité.This study examines the recent architecture of the Bui Thi Xuan neigbourhood in Hanoi, Vietnam. Since 1986, when the doi moi policy came into effect, the country has been experiencing a strong economic boom. As a result, the private sector plays an active part in the construction and renovation industries. The research focuses on a particular type of urban infill, where tall concrete structures are built within narrow and deep lots, and are often quickly renovated thereafter. The purpose of this study is to determine how these buildings can be physically and spatially modified in response to an already occurring urban densification. A systemic analysis of the building stock will reveal the viability of such options in terms of adaptability and environmental quality criteria. Recent renovations will then show how these structures are actually evolving within their environment. The research concludes with a demonstration of how these buildings, as they stand, have an under-exploited capacity to provide a healthy and adaptable environment.

Mestrado em Ciências EconómicasO presente estudo faz a análise dos principais factores explicativos das exportações e da despesa em investigação e desenvolvimento (I&D) das PME´s e das grandes empresas a operar em Portugal, para o período 2004-2008. A partir de uma amostra constituída por 200 PME´s e por 30 grandes empresas exportadoras o estudo utiliza dados de painel e os estimadores de efeitos fixos e efeitos aleatórios para estimar os efeitos sobre as exportações e sobre a despesa em I&D. Em relação às exportações, o estudo conclui pelo efeito positivo do aumento da produtividade e da despesa em I&D tanto nas PME´s como nas grandes empresas e que as PME´s estrangeiras exportam mais que as PME´s nacionais. Quanto às determinantes da despesa em I&D o estudo conclui que o aumento dos capitais próprios e dos resultados líquidos tem um efeito positivo sobre as despesas em I&D nas grandes empresas ao passo que nas PME´s é o aumento das exportações que leva ao aumento das despesas em I&D, tendo o aumento dos resultados líquidos um efeito negativo.
This study analyses the main determinants of exports and research and development (R&D) expenses of small and medium enterprises (SME) and large companies operating in Portugal during the period 2004-2008. From a sample of 200 SMEs and 30 major exporting companies, the study uses a panel data analysis and fixed-effects and random-effects estimators to estimate the effects on exports and on R & D. Regarding exports, the study found a positive effect in terms of increased productivity and R & D in both SMEs and large companies. The results also suggest that SMEs that are owned by foreign enterprises export more than national SMEs. In relation to the determinants of spending on R & D, the study concludes that the increase in equity and net income has a positive effect on R & D spending in large companies, while in SMEs, increased expenditure on R & D is a consequence of increasing exports, whereas the increase in net income has a negative effect on R & D.

Full textAbstract:
Este estudo teve como objetivo avaliar do efeito da aplicação tópica de um verniz e solução experimental de TiF4, comparando-os ao verniz e solução de NaF, sobre o processo de des-remineralização do esmalte dentário in situ. Para tal, 132 blocos de esmalte bovino (4x4mm) foram selecionados pela microdureza de superfície, sendo que em metade deles foi produzida lesão de cárie artificial em solução desmineralizante (pH 5,0, 6 dias). Na seqüência, foi determinada a microdureza de superfície pós-lesão. A outra metade dos blocos permaneceu hígida. Onze voluntários participaram de 3 fases cruzadas (14 dias cada, washout de 7 dias), boca-dividida e cegas, nas quais utilizaram aparelhos palatinos com 4 amostras de esmalte por fase (2 hígidas e 2 desmineralizadas), sendo que cada tipo de amostra recebeu um tipo de tratamento (verniz ou solução). Em todas as amostras permitiu-se o acúmulo de placa dentária. Em uma fase (Fase A), foram aplicados agentes a base de NaF a 5,42% (2,45% F- e pH 5,0), em outra fase (Fase B), foram utilizados agentes a base de TiF4 a 4% (2,45% F- e pH 1,0), e na última fase (Fase C) foram utilizados agentes placebos (verniz sem flúor pH 5,0 e sem tratamento). Os tratamentos foram realizados in vitro (verniz-6 h e solução-1 minuto). Durante o período in situ, os voluntários aplicaram solução de sacarose a 20%, 8x5min ao dia, sobre os blocos hígidos, para provocar a desmineralização. Já para os blocos desmineralizados nenhum procedimento foi realizado, para permitir a remineralização. A microdureza de superfície final foi realizada, para o cálculo da porcentagem de variação de microdureza de superfície, assim como a microdureza longitudinal e microradiografia transversal, para o cálculo das perdas de microdureza e volume mineral integradas, respectivamente. Os dados foram submetidos à ANOVA-RM/ Tukey-Kramer, teste t pareado e ANOVA a dois critérios/Bonferroni (p<0,05). Houve uma redução significativa da desmineralização superficial e um aumento significativo da remineralização superficial do esmalte in situ pelos tratamentos com verniz e solução de TiF4, em comparação aos controles. Pôde-se constatar ainda que os tratamentos com o verniz de NaF, verniz de TiF4 e solução de TiF4 foram efetivos na redução da desmineralização subsuperficial in situ. No entanto, observou-se que o protocolo experimental não permitiu uma adequada remineralização de subsuperfície in situ. Com base nos resultados, pode-se concluir que o verniz e a solução de TiF4 parecem ser promissores na prevenção da desmineralização, porém em relação à remineralização mais estudos in situ são necessários.The aim of this study was to evaluate the effect of the experimental TiF4 varnish and solution, comparing with NaF solution and varnish, on dental enamel de-remineralization in situ. For that, 132 bovine enamel samples (4x4 mm) were selected using surface microhardness, and half of them were submitted to artificial caries lesion formation using a demineralizing solution (pH 5.0, 6 days). The surface microhardness after the demineralization was measured. The other half of the samples remained sound. Eleven volunteers took part in this cross-over, split-mouth and double-blind study performed in 3 phases of each 14 days (washout of 7 days). Four enamel samples were worn in palatal appliances (2 sound and 2 demineralized), being each type of sample submitted to one treatment (varnish or solution). The dental plaque accumulation was allowed on all samples. In phase A, 5.42% NaF varnish/solution was applied (2.45% F-, pH 5.0); in phase B, 4% TiF4 varnish/solution was used (2.45% F-, pH 1.0) and at the last phase (phase C) the placebo treatments were performed (placebo varnish pH 5.0 and no-treatment). The treatments were performed in vitro (varnish-6h and solution-1min). During the in situ phase, the volunteers dripped a solution containing 20% weight/volume (w/v) sucrose on the sound samples for 5 min, 8 times a day, to provoke demineralization. While on the demineralized samples nothing was done, in order to allow remineralization. The final surface microhardness was analyzed for the calculation of the % of surface microhardness change, as well as the cross-sectional hardness and the transversal microradiography, for the calculation of the integrated loss of microhardness and mineral volume, respectively. The data were submitted to RM-ANOVA/ Tukey-Kramer, t test and 2-way ANOVA/ Bonferroni (p<0.05). There was a significant reduction of the surface enamel demineralization and increase of surface remineralization by the treatments with TiF4 varnish and solution compared to control in situ. The treatments with NaF varnish, TiF4 varnish and solution were able to reduce the subsurface demineralization in situ. However, the experimental protocol did not allow the subsurface remineralization in situ. Based on the results, it can be concluded that the TiF4 varnish and solution seem to be promising products for preventing demineralization, but for the remineralization more studies need to be conducted.

Resumo: A epilepsia constitui um problema médico-social de alta relevânci_ atingindo pessoas em todo o mundo. Entretanto os preconceitos e reações estigmatizantes por parte da família e da sociedade, constituem ainda empecilho para que os epiléticos possam exercer seus direitos humanos básicos, enfim, viver com qualidade. Buscou-se nesse estudo, verificar o impacto da epilepsia na vida de crianças e adolescentes epiléticos, através da abordagem de diversos fatores relacionados ao distúrbio, crenças, estigmas, interação com a família, ajustamento social, comportamentos, emoções, o lazer e a escola enfocando a qualidade da interação do aluno epilético com a Educação Física. Para tanto, o trabalho envolveu 40 crianças e adolescentes epiléticos de 10 a 16 anos associados a Associação de Epilepsia do Sudeste Goiano, seus familiares (40 pais ou mães) e 15 professores de Educação Física aos quais foram aplicados os respectivos questionários. Utilizou-se também de entrevistas com 2 médicos neurologistas. Tendo em vista os objetivos desse estudo, constatou-se que a desinformação e a incompreensão da epilepsia por parte dos pais e professores de Educação Física inviabilizam ou limitam oportunidades que favoreçam o desenvolvimento integral do epilético, o qual manifesta dificuldades ou alterações de ordem biopsicossociais, que interferem no processo de construção de sua identidade e das suas relações com o mundo e consigo mesmos. Necessário se faz que os pais, professores e os próprios epiléticos compreendam e tenham uma visão mais otimista frente a epilepsia e a vida, banindo estereótipos e criando atitudes favoráveis a uma boa adaptação no ambiente familiar, social e escolar

However, the prejudices and reactions stigmatizing from the family and the society still make difficult for the epileptics to exercise their basic human rights, and finally live with quality. It was searched in this study, verify the impact of the epilepsy in the children and adolescent epileptics' life, through the approach of several factors related to the disturbance, faiths, stigmas, interaction with the family, social adjustment, behaviors, emotions, leisure and school, focuzing the quality of the interaction of the epileptic with the Physical Education, all decisive in the accomplishment expectations or personal and social acting, essential to a good life quality. This work involved 40 epileptic children and adolescents from 10 to 16, members of the "Associação de Epilepsia do Sudeste Goiano", their relatives (40 parents) and 15 Physical Education Teachers, who answered the respective questionnaires. Interviews with 2 neurologists were also helped. After checking the objectives on the case, it was verified that the noninformation and the incomprehension of the epilepsy by the parents and Physical Education Teachers, made unfeasible or limit opportunities that favor the whole epileptic development, which manifests difficulties or biopsycossocial order alterations, that interfere in the process of construction ofthe identity and relationships with the world and themselves. It's necessary that the parents, teachers and the own epileptics, understand and have a more optimistic view towards epilepsy and life, banishing stereotypes and creating favorable attitudes to a good adaptation in the family, social and school atmosphere

Resumo: A obesidade e as dislipidemias geralmente estão associadas, e na maior parte dos casos possuem origem complexa, sendo decorrentes da interação entre os fatores ambientais e fatores genéticos. Dentre os fatores genéticos já conhecidos encontram-se genes relacionados ao metabolismo, como o gene FTO (Fat Mass and Obesity Associated) e os genes dos transportadores ABC. Polimorfismos de nucleotídeo único (SNPs) no gene FTO foram associados com o ganho de peso, enquanto os transportadores ABC estão relacionados com o efluxo de colesterol, e, nesse trabalho, foram analisados SNPs dos genes ABCA1, ABCA7 e ABCG1. Visto isso, o objetivo desse estudo é avaliar se há influência de polimorfismos nesses genes sobre variáveis antropométricas (índice de massa corporal ajustado para idade e sexo (IMC escore-Z), circunferência abdominal (CA), circunferência da cintura (CC), gordura corporal (GC) e massa magra (MM)) e bioquímicas (glicose em jejum, glicose 120, insulina em jejum, insulina 120, HOMA-IR (do inglês homeostasis model assessment of insulin resistance), QUICKI (do inglês quantitative insulin sensitivity check index) e perfil lipídico) de 557 crianças e adolescentes (eutróficos, sobrepeso e obesos) estudantes de escolas de Curitiba (PR), além de verificar o efeito de tais polimorfismos nas mudanças desses marcadores em resposta a um programa de exercícios físicos. A genotipagem foi realizada por ensaio de discriminação alélica. As análises estatísticas realizadas foram contagem direta dos genótipos, cálculo de frequência alélica, comparação de médias (teste T e teste Mann Whitney), análise de regressão múltipla e predição de risco. Todos os SNPs analisados promoveram variação significativa em alguma das variáveis analisadas. Com relação ao gene FTO, o alelo A do SNP rs9939609 foi associado a um aumento da insulina e HOMA-IR, e diminuição de QUICKI. Em relação aos genes dos transportadores ABC, o alelo C do SNP rs1800977 (ABCA1) foi associado a aumento no IMC escore-Z, CA, GC, insulina 120 e redução em QUICKI; o alelo A do SNP rs2230806 (ABCA1) foi associado a aumento no IMC escore-Z, CA e redução em %MM; o alelo C do SNP rs2279796 (ABCA7) foi associado à maior IMC escore-Z; o SNP rs692383 (ABCG1) foi associado à maior IMC escore-Z, CA, HDL-C, glicose, insulina e HOMA-IR e o alelo G do SNP rs3827225 (ABCG1) foi associado à maior VLDL-C e glicose. Com relação ao efeito na resposta aos exercícios físicos, os genes FTO, ABCA7 e ABCG1 não apresentaram interação, enquanto o alelo C do SNP rs1800977 (ABCA1) foi associado à maior redução de IMC escore-Z e maior aumento de QUICKI em resposta ao exercício e o alelo A do SNP rs2230806 (ABCA1) foi associado à maior ganho de MM. Nesse trabalho nós verificamos os efeitos dos polimorfismos analisados em variáveis relacionadas ao metabolismo (adiposidade, metabolismo da glicose e de lipídeos), sendo que alguns desses polimorfismos também interagiram com os programas de exercícios físicos aplicados. Os resultados obtidos corroboram e abrem novas perspectivas de estudo quanto ao papel da interação entre fatores ambientais e genéticos na prevenção e tratamento de patologias complexas, como a obesidade e as dislipidemias, no sentido de tornar tais medidas cada vez mais individualizadas.

Abstract: Obesity and dyslipidemias are usually associated, and in most cases have complex origin, resulting from interaction between environmental and genetic factors. Among these already know genetic factors there are genes related to metabolism, such as FTO (Fat Mass and Obesity Associated) and the ABC transporters genes. Single nucleotide polymorphisms (SNPs) in FTO gene are associated to weight gain, while ABC transporters are related to cholesterol efflux, and SNPs in ABCA1, ABCA7 and ABCG1 genes were analyzed in this work. The objective of this study is to evaluate the influence of polymorphisms in these genes on anthropometric (body mass index adjusted for age and sex (BMI Z-score), abdominal circumference (AC), waist circumference (WC), fat mass (FM) and lean body mass (LBM)) and biochemical variables (fasting glucose, glucose 120, fasting insulin, insulin 120, HOMA-IR (homeostasis model assessment of insulin resistance), QUICKI (quantitative insulin sensitivity check index) and lipid profile) of 557 children and adolescents (normal weight, overweight and obese) in Curitiba (PR), and verify these polymorphisms effects in the changes of these markers in response to a physical exercise program. Genotyping was carried out by allelic discrimination assay. The statistical analyzes made were direct counting of genotypes, allelic frequency calculation, comparison of means (T test and Mann-Whitney test), multiple regression analysis and risk prediction. All the analyzed SNPs promoted significant variation in some of the variables. Regarding FTO gene, the rs9939609 SNP A-allele was associated to higher insulin and HOMA-IR, and reduced QUICKI. In relation to the ABC transporter genes, SNP rs1800977 C-allele (ABCA1) was associated to higher BMI-Z score, AC, FM and insulin 120 increase and QUICKI reduction; SNP rs2230806 (ABCA1) A-allele was associated to higher BMI-Z score and AC and %LBM reduction; SNP rs2279796 (ABCA7) C-allele was associated to higher BMI Z-score; SNP rs692383 (ABCG1) was associated to higher BMI Z-score, AC, HDL-C, glucose, insulin and HOMA-IR, and SNP rs3827225 (ABCG1) G-allele was associated to higher VLDL-C and glucose. Regarding the effect on physical exercise response, FTO, ABCA7 and ABCG1 genes did not shown interaction, whereas rs1800977 (ABCAI) C-allele was associated to higher reduction of BMI Z-score and increase in QUICKI in response to physical exercise and rs2230806 SNP (ABCA1) A-allele was associated to higher gain of LBM. In this study, we verified the effects of the polymorphisms analyzed on variables related to metabolism (adiposity, glucose metabolism and lipid metabolism), and some of these polymorphisms also interacted with the applied physical exercise programs. The results obtained corroborate and open new perspectives on the role of the interaction between environmental and genetic factors in the prevention and treatment of complex pathologies, such as obesity and dyslipidemias, in order to make these measures more individualized. Key-words: Obesity, dyslipidemia, physical exercise, FTO, ABCA1, ABCA7, ABCG1, rs9939609, rs1800977, rs2230806, rs2279796, rs692383, rs3827225.

Um grupo é uma reunião de indivíduos que buscam um objetivo em comum e normalmente estabelecem associações que uma vez constituídas, resultam, em geral, em organizações. Para que as organizações alcancem seus objetivos, fixam processos, os quais perpassam todas as ações empreendidas e estão presentes na consecução de todos os produtos organizacionais. Para gerir esses processos, surgem técnicas como o business process management (BPM) que sistematizam e consolidam, de forma abrangente, disciplinas que compartilham a crença de que uma abordagem organizacional centrada em processos leva a melhorias substanciais em termos de desempenho e conformidade com o momento atual. Atrelada a esse ambiente organizacional encontra-se a tecnologia da informação e comunicação (TIC) que engloba os sistemas de informação utilizados por uma organização, bem como as redes de comunicação que possibilitam a colaboração numa esfera interpessoal. A colaboração também é percebida em grupos informais, inclusive em grupos de pesquisa, coligações formais vinculadas às instituições nacionais de pesquisas, cuja função é investigar assuntos específicos relacionados a áreas de pesquisa de seus interesses. Assim, já que a dinamicidade do ambiente organizacional requisita um melhoramento contínuo do desempenho dos grupos, inclusive aqueles que realizam pesquisa científica, é factível crer que o BPM também pode auxiliar os grupos de pesquisa a aperfeiçoarem seus processos colaborativos. Por este ângulo, a presente pesquisa debruçou-se sobre o mapeamento dos processos colaborativos executados pelos grupos de pesquisa sob a perspectiva do BPM. Para tanto, o estudo realizou uma survey com aprofundamento em duas fases. A primeira por meio da aplicação de questionários aos grupos de pesquisa vinculados à UFPE. Na segunda fase, foram realizadas entrevistas com membros de nove grupos, as quais serviram de subsídio para diagramação dos processos taxados como os mais colaborativos pelos próprios grupos. Como resultados, foram encontradas realidades em comum entre os grupos, as quais se acham modeladas e apresentadas neste estudo, e sobre elas apontam-se possíveis melhorias, principalmente com a ampliação de uso de artefatos de TIC.
A group is a gathering of individuals seeking a common goal and usually establish associations that once constituted, resulting generally in organizations. For organizations to achieve their goals, establish processes that underlie all actions taken and are present in achieving all organizational products. To manage these processes, there are techniques such as business process management (BPM) that systematize and consolidate disciplines who share the belief that an organizational approach focused on processes, leads to substantial improvements in terms of performance and compliance with the current time. Linked to this organizational environment is the information and communication technology (ICT) encompassing the information systems used by an organization and communication networks that enable collaboration in an interpersonal level. Collaboration is also perceived in informal groups, including research groups, formal coalitions linked to national research institutions, whose function is to investigate specific issues related to research areas of their interests. Thus, since the dynamics of the organizational environment requests a continuous improvement of the performance of groups, including those carrying out scientific research, it is feasible to believe that the can also help research groups to enhance their collaborative processes. From this perspective, this research has looked at the mapping of collaborative processes carried out by research groups under the BPM perspective. Therefore, the study conducted a survey with deepening in two stages. The first through the application of questionnaires to research groups linked to UFPE. In the second phase, interviews with the nine group members were made, which served as a subsidy for diagramming the processes taxed as more collaborative by the groups themselves. As a result, realities were found in common between the groups, which find themselves modeled and presented in this study, and on they point to possible improvements, especially with the expansion of ICT devices to use.

Resumo: O objetivo deste estudo foi analisar o efeito da anestesia no desfecho perinatal de mulheres hipertensas obesas submetidas à cesárea. Trata-se de estudo observacional prospectivo de 98 gestantes hipertensas e seus recém-nascidos, submetidas à cesárea sob anestesia subaracnoidea. As gestantes foram divididas em quatro grupos de acordo com seus índices de massa corporal (IMC): normal, sobrepeso, obesidade I e obesidade II. Dados demográficos e cirúrgicos maternos, bem como os valores de amostras de sangue venoso do cordão umbilical e características neonatais foram comparados entre os quatro grupos. Mediana e percentis foram utilizados (tendência de distribuição não-normal) e variáveis categóricas foram expressas em valores absolutos e percentuais. Quase 70% das mulheres eram brancas. A parada da dilatação como indicação para cesárea diferiu entre os grupos (p = 0,002): 33,33% do grupo obesidade II, 8,69% do grupo obesidade I, 6,66% do grupo normal e zero no grupo com sobrepeso. Pressão arterial sistólica máxima foi maior em mulheres com IMC normal (p = 0,002). Valores de peso ao nascimento, estatura, pH do sangue venoso do cordão umbilical, lactato, meta-hemoglobina, reticulócitos e eritroblastos foram semelhantes entre os grupos. Escores de New Ballard, Apgar e Silverman-Andersen não diferiram significativamente entre os grupos analisados. Somente cinco recém-nascidos foram internados na unidade neonatal, 25 foram levados para o berçário, onde permaneceram até alta para o alojamento conjunto e 68 permaneceram com suas mães após o nascimento. Não houve influência da anestesia subaracnoidea no desfecho perinatal de gestação de hipertensas obesas
Abstract: The aim of this study was to analyze the effect of anesthesia on perinatal outcome of hypertensive obese women undergoing cesarean delivery. This is a prospective observational study of 98 cesarean sections in hypertensive pregnant women, and their newborns, under spinal anesthesia. Women were divided into four groups according to their body mass indices: normal, overweight, obese I, and obese II. Demographic and surgical maternal data, values of cord blood samples and neonatal outcomes were compared between the four groups. Median and percentiles were used (tendency of non-normal distribution) and categorical variables were expressed as absolute values and percentage. Almost 70% of the women were white. The arrest of dilation, which was the indication for cesarean delivery, differed between the groups (p = 0.002): 33.33% in the obese II, 8.69% in the obese I, 6.66% in the normal body mass index, and zero in the overweight group. Maximum systolic blood pressure was higher in women with normal body mass index (p = 0.002). Birth weight, height, umbilical venous cord blood pH, lactate, methemoglobin, reticulocyte, and erythroblast counts were similar between groups. New Ballard, Apgar and Silverman-Andersen scores did not differ significantly between the groups analyzed. Only five newborns were admitted to the neonatal unit, 25 were taken to the nursery, where they stayed until discharge when they joined their mothers and 68 remained with their mothers. There was no adverse effect of spinal anesthesia on neonatal outcome of hypertensive obese pregnant women

Resumo: A privatização dos serviços de serviços de telefonia em março de 1998, não trouxe somente para o Brasil uma mudança de comportamento entre a oferta e demanda no Serviço Fixo e Móvel de telefonia, como também na definição e avaliação de novos serviços, acarretando por sua vez, uma mudança na definição da qualidade de prestação de serviços para o usuário final. Este trabalho realiza um histórico das telecomunicações para entendermos a origem da privatização das telecomunicações. A seguir, analisa os conceitos da prestação de serviço para daí informar a padronização dos serviços com a aplicação das normas da ISO 9000, e das normas criadas pela ANATEL. Em conseqüência, são estudas as categorias de reclamações fundamentadas do Procon de São Paulo para avaliar a qualidade na prestação de serviço. Desta forma, as categorias estudadas no período de 2000 a 2001 resultaram ser dependentes do ano, demonstrando que tal falha precisa ser melhorada através de uma nova integração entre a gestão administrativa e técnica das operadoras de telefonia, como também da presença da ANATEL na solução e melhoria da prestação de serviço. Finalmente, são sugeridas ferramentas de avaliação de PDCA e GAP para as empresas atingirem uma melhoria contínua da qualidade
Abstract: The privatization of the services of the telephone services in March of 1998 not only brought to Brazil a change in the relationship between the supply and demand in the wireline and mobile telephone system service, but also in the definition and evaluation of new services, causing, in turn, a change in the definition of the quality of the services provided to the final user. This paper does a historical research of the telecommunications to enable us to understand the beginning of the privatization of the telecommunications. Afterwards, it analyses the concepts of service providing in order to inform the standardization of services with the application of the ISO 9000 rules, and the rules created by ANATEL. Consequently, it is made a study of the complaints received by PROCON in São Paulo to evaluate the quality of the service provided. As a result of this analysis, the categories studied in the period 2000 through 2001 resulted in being dependent on the year, showing that this fault needs to be improved through a new integration between the administrative and technical management of the telephone system operators, as well as the presence of ANATEL in the solution and improvement of the services provided. Finally, tools of evaluation of PDCA an GAP are suggested to the companies to achieve a continuous improvement of the quality

A partir da análise do filme Alice nas Cidades do diretor alemão Wim Wenders, formulo questões sobre o cinema e as imagens, problematizando a relação do olhar na sociedade moderna. Tendo em vista que somos constantemente submetidos a uma proliferação incessante de imagens, em consequência disso temos também sofrido a perda de um olhar mais atento, que possa questionar os códigos visuais e possibilite uma visão crítica em relação a eles. Sendo o cinema a base da pesquisa, meu suporte teórico principal é a filosofia do cinema de Gilles Deleuze, de modo que as propostas criadas por ele em Cinema 1: A Imagem-Movimento e Cinema 2: A Imagem-Tempo fundamentam a grande maioria dos capítulos deste trabalho. Primeiramente procuro entender os principais conceitos sobre as imagens cinematográficas formulados pelo autor em Cinema 1, em que ele trabalha apoiado nos filmes e nos diretores do que ele intitula cinema clássico, e a partir do qual ele desenvolve sua teoria da imagem-movimento e suas variações; logo, analiso Cinema 2, livro em que Deleuze trabalha a partir do intitulado cinema moderno, e descreve como este se enquadraria dentro do que ele chama de a imagem-tempo. A seguir, me concentro em entender o porquê de considerar Alice nas Cidades um filme mais ligado a imagem-tempo do que a imagem-movimento. Faço também referência à inter-relação entre cinema e história, bem como desenvolvo analogias entre fragmentos do filme e outras formas de expressão como a literatura, fotografia e as artes plásticas, de forma a tramar uma análise abrangente do filme, onde as relações improváveis viraram possibilidades de leitura.

The aim of this project is a reconstruction of a former kindergarten building in Žďár nad Sázavou to a community center with several functional units. The existing building was bulit in 1960s. The site is located on the border of the old and new buildings – on one side, there is a Stalingrad housing estate from the 1950s built from brick houses in the socialist realism style. On the other side of the site are built new family houses, which are quickly expanding. The smaller part of the object is still used, the rest is abandoned. The house is surrounded by a large garden. The garden is defined by a fence and trees in a way, which creates a barrier, so the building does not communicate with surroundings in any way. The aim of the project is to create a centre of Stalingrad connected with surroundings and creating a meeting place for communities living in the area by using building interventions.

The diploma thesis follows the analytical part of the previous semester, which examined the possibilities, risks and potential of the city. The main starting point is the work with the existing building - reconstruction and extension of the original kindergarten building. Compared to the conventional new "green meadow" construction, this assignment emphasizes the use of existing values, the concentration and strengthening of the existing city as opposed to the contemporary colonization of the free landscape. The design of a building modification of an existing building must also be based on the perception of the continuity of the development, in particular the constructional nature of the building, so that the newly designed "layer" of development does not become a denial of the previous layers.

The aim of this project is a reconstruction of a former kindergarten building in Žďár nad Sázavou to a community center with several functional units. The existing building was bulit in 1960s. The site is located on the border of the old and new buildings – on one side, there is a Stalingrad housing estate from the 1950s built from brick houses in the socialist realism style. On the other side of the site are built new family houses, which are quickly expanding. The smaller part of the object is still used, the rest is abandoned. The house is surrounded by a large garden. The garden is defined by a fence and trees in a way, which creates a barrier, so the building does not communicate with surroundings in any way. The aim of the project is to create a centre of Stalingrad connected with surroundings and creating a meeting place for communities living in the area by using building interventions.
