Full textNowadays, a considerable part of usability evaluations carried out during the software development lifecycle is conducted at later stages. Some of these assessments depend on the creation of fully functional prototypes, so they can be applied, and they re commonly performed after the development and deployment of software. This factor contributes significantly to the increase in cost of production. In this sense, from the research of prototyping, usability engineering and the conduction of a systematic review, this work presents an approach that allows the usability evaluation anticipation, through the use of mixed-fidelity prototypes created via the use of a computational tool. This tool assists in the creation and simulation of prototype interfaces, and enables collecting the following metrics of usability, for further analysis: task success, giving up on tasks, time on task, effort, screen balance, screen symmetry, screen balance, sequencing, order and complexity and system usability scale. In addition to the metrics that are collected by the tool automatically, other metrics are proposed to be collected from the observation of users using the prototypes created: partial success of the task, number of errors, help and documentation, time help, anger or frustration. The analysis of the obtained metrics point to areas of the system with potential usability problems. Moreover, the execution of new tests using the interfaces refined with the approach aid allow us to quantify the improvements resulting of the layout changes. In addition to the approach, the work presents its use in an experiment conducted with users. This experiment showed that, although not ali the metrics that can be collected from prototypes contribute to the refinement of interfaces, it was still possible to reduce the number of usability problems by just analyzing the results of the metrics.
Hoje em dia, uma consider?vel parte das avalia??es de usabilidade realizadas nos ciclos de desenvolvimento de software ? conduzida em etapas mais avan?adas nestes ciclos. Algumas destas avalia??es dependem ainda que prot?tipos totalmente funcionais sejam constru?dos, para que possam ser aplicadas, sendo comumente realizadas ap?s o desenvolvimento e implanta??o do software. Este fator contribui significativamente para o aumento no custo de produ??o. Neste sentido, a partir de pesquisas sobre prototipa??o e engenharia de usabilidade e da condu??o de uma revis?o sistem?tica sobre m?tricas para avalia??o de usabilidade, o presente trabalho apresenta uma abordagem que permite que a avalia??o de usabilidade seja antecipada, efetuando-a por meio da utiliza??o de prot?tipos de fidelidade mista - elaborados mediante o uso de uma ferramenta computacional. Esta ferramenta auxilia na cria??o e simula??o de prot?tipos de interfaces, al?m de permitir coletar as seguintes m?tricas de usabilidade, para posterior an?lise: sucesso de tarefas, desist?ncia de tarefas, tempo na tarefa, esfor?o, equil?brio de tela, simetria de tela, balan?o de tela, seq?enciamento, ordem e complexidade e escala de usabilidade do sistema. Al?m das m?tricas que s?o coletadas pela ferramenta, de forma autom?tica, s?o propostas as seguintes m?tricas, a serem coletadas a partir da observa??o dos usu?rios utilizando os prot?tipos criados: sucesso parcial de tarefa, n?mero de erros, auxilio e documenta??o, tempo de ajuda e raiva ou frustra??o. A an?lise das m?tricas obtidas permite apontar ?reas do sistema com poss?veis problemas de usabilidade. Al?m disto, a execu??o de novos testes utilizando as interfaces refinadas com o aux?lio da abordagem permite quantificar as melhorias realizadas pelas mudan?as de layout efetuadas. Al?m da abordagem, o trabalho apresenta seu uso em um experimento realizado com usu?rios. Este experimento permitiu verificar que, apesar de nem todas as m?tricas pass?veis de serem coletadas de prot?tipos contribu?rem para o refino das interfaces, ainda assim foi poss?vel reduzir o n?mero de problemas de usabilidade.

Objective: To evaluate CT phenotypes, airflow limitation and exacerbation-like episodes in heavy smokers. Methods: This cross-sectional study enrolled 172 smokers, with > 30 pack-years exposure, who underwent pulmonary function tests (PFTs) and quantitative computed tomography (QCT). Subjects were classified by presence or absence of airflow limitation according to the current GOLD criteria of post-bronchodilator FEV1/FVC < 0,7. QCT analysis of data in Airway Inspector software resulted in the establishment of two disease-predominant phenotypes groups: emphysema-predominant (EP) (>6 % of pixels < -950 HU) and non-emphysema-predominant (NEP) (<6 % of pixels < -950 HU). Results: The overall mean age was 63.39 ? 6.04 years, 58% were men, mean packyears smoking history was 70.7 ? 34.32 and mean body mass index (BMI) was 26.96 (?5.69). Most of the 58% of male subjects were distributed in the airflow limitation group, which had also a higher mean pack-years smoking history (77.20 ? 38.03 vs. 60.53 ? 24.50, p=0.009) and mean emphysema index (17.01 ? 9.96 vs. 4.52 ? 3.55, p<0.001), than the group without airflow limitation. About 8.9% of those subjects with no airflow limitation had exacerbation-like episodes, and 23,8% show emphysemapredominant phenotype. According to QTC analysis, the EP group exhibited worse FEV1/FVC mean ratio (55.62 ? 13.3) compared to the NEP (79.10 ? 9.78), p<0.001. Conclusions: Despite of no persistent airflow limitation, 8,9% of the heavy smokers had exacerbation-like episodes and QCT findings of emphysema. Those in the EP phenotype group, had worse PFTs values, higher smoking history, male predominance and also experienced more exacerbation-like episodes than NEP.
Objetivo: avaliar fumantes com alta carga tab?gica, analisando padr?es espirom?tricos, fenot?picos tomogr?ficos e desfechos cl?nicos. Material e M?todo: Foi realizado um estudo transversal com 172 fumantes de um protocolo de rastreamento para detec??o de c?ncer de pulm?o, com carga tab?gica acima de 30 anos-ma?o, que realizaram pelo menos uma tomografia computadorizada e uma espirometria dentro de um intervalo de um ano. Inicialmente os pacientes foram separados em dois grupos, com fun??o pulmonar normal (FPN) e fun??o pulmonar alterada (FPA), e posteriormente fez-se uma suban?lise de acordo com o fen?tipo tomogr?fico. Resultados: encontrou-se idade m?dia de 63,39 ? 6,04 anos, a maioria eram homens (58%) e a carga tab?gica m?dia foi 70,7 ? 34,32 anos-ma?o. Os pacientes com FPA experimentaram mais infec??es respirat?rias no ano anterior do que os indiv?duos com FPN, respectivamente (n = 29 e n = 5; p = 0,05). Os participantes do grupo com FPN eram mais jovens e com maior propor??o de mulheres que o grupo com FPA, respectivamente (61,48 ? 5,32 anos; 64,61 ? 6,17 anos; p <0,001; n = 39 (58%), n = 33 (31%); p <0,001). A carga tab?gica dos indiv?duos com FPN era inferior em rela??o ao grupo com FPA, respectivamente (60,53 ? 24,50 anos-ma?o e 77,20 ? 38,03 anos-ma?o; p<0.009). Cerca de 9% dos indiv?duos com fun??o pulmonar normal apresentaram epis?dios infecciosos no trato respirat?rio e quase um quarto dos participantes com FPN, 23,8%, tinham fen?tipo enfisematoso na an?lise tomogr?fica. O grupo com fen?tipo tomogr?fico enfisema-predominante (EP) apresentou os piores resultados de fun??o pulmonar em compara??o com o grupo de fen?tipo n?o-enfisematoso (NEP). Conclus?o: Neste estudo mesmo os fumantes com FPN apresentaram achados tomogr?ficos compat?veis com enfisema, assim como desenvolveram epis?dios de infec??o no trato respirat?rio similares a exacerba??o do DPOC. O fen?tipo EP teve os piores ?ndices de fun??o pulmonar e maior n?mero de epis?dios infecciosos no trato respirat?rio nos ?ltimos 12 meses.

Full textThe nanometric powders have special features that usually result in new properties, originating applications or expanding them in various fields of knowledge. Because having a high area/volume ratio, phenomena such as superficial strength of adsorption becomes greater than the weight of the powder which makes more difficult its handling. The high power of agglomeration of these powders requires study and development of equipments to enable its management into the plasma torch. The objective of this work is to develop a powder feeder which can solve the mainly problems about insertion of powder into the thermal spray developed in the laboratory of plasmas, which are carried out with plasma torch arc not transferred (plasma spray). Therefore, it was made a aluminum s powder feeder and tests were performed to verify their operation and determine its rate of deposition by spraying powders of niobium pentoxide (Nb2O5) and titanium dioxide (TiO2) with particle sizes less than 250 mesh (<0.063 mm). We used masses of 0.5 g - 1.0 g and 1.5 g of each powder in tests lasting 15 seconds - 20 to 25 seconds for each mass. The tests were performed in two ways: at atmospheric pressure using argon gas with a flow of 9 l / min as carrier gas and through a Venturi pipe also using argon gas with a flow of 9 l / min as carrier gas and with a flow of 20 l/min as the feed gas passing through the Venturi pipe. The powder feeder developed in this paper is very easy to be handling and building, resulting in feeding rate of 0.25 cm3/min - 1.37 cm3/min. The TiO2 showed higher feeding rates than the Nb2O5 in all tests, and the best rates were obtained with tests using mass 1.5 g and time of 15 seconds, reaching feeding rate of 1.37 cm3/min. The flow of feed had low interference in feeding rate during the tests
Os p?s nanom?tricos apresentam caracter?sticas especiais que geralmente resultam em novas propriedades, ampliando ou originando melhores aplica??es nas diversas ?reas de conhecimento. Devido ao fato de possuir uma alta raz?o ?rea/volume, fen?menos como a for?a de adsor??o de superf?cie tornam-se superiores ao peso, dificultando o seu manuseio. O alto poder de aglomera??o dificulta processos como o de alimenta??o de p?s em tochas de plasma, por exemplo. O objetivo do presente trabalho ? desenvolver um alimentador de p?s, para trabalhos com aspers?o t?rmica, que s?o realizados em tocha de plasma de arco n?o transferido (plasma spray). Para tanto, foi confeccionado um dispositivo em alum?nio, sendo realizados testes para verificar seu funcionamento e determinar sua taxa de alimenta??o durante aspers?o de p?s de pent?xido de ni?bio (Nb2O5) e di?xido de tit?nio (TiO2), com tamanhos de part?culas inferiores a mesh 250 (< 0,063 mm). Foram utilizadas massas de 0,5 g - 1,0 g e 1,5g de cada p?, em testes com dura??o de 15 s - 20 s e 25 segundos para cada massa. Os ensaios foram realizados de duas maneiras: ? press?o atmosf?rica utilizando-se g?s arg?nio com fluxo de 9 l/min como g?s de arraste e atrav?s de um tubo de Venturi utilizando tamb?m o g?s arg?nio com fluxo de 9 l/min como g?s de arraste e com fluxo de 20 l/min como g?s de alimenta??o, passando pelo interior do tubo de Venturi. O alimentador de p? desenvolvido neste trabalho ? de f?cil constru??o e manuseio, obtendo-se taxas de alimenta??o de 0,25 cm3/min - 1,37 cm3/min. O TiO2 apresentou maiores taxas de alimenta??o que o Nb2O5 em todos os testes, e as melhores taxas foram obtidas com os ensaios utilizando massa de 1,5 g e tempo de 15 segundos, atingindo taxa de alimenta??o de 1,37 cm3/min. O fluxo de alimenta??o apresentou pouca interfer?ncia na taxa de alimenta??o durante a realiza??o dos testes

Full textLas nuevas herramientas biotecnológicas ofrecen una amplia gama de posibilidades de desarrollo en todas las áreas donde el hombre se desenvuelve. La agricultura no esta ajena a esta posibilidad. El trigo de pan ( Triticum aestivum L), uno de los alimentos más importantes del mundo, puede beneficiarse significativamente al incorporar el uso de esta nueva tecnología dentro del proceso de creación de nuevas variedades. Los microsatélites o SSR (Simple Sequence Repeats), marcadores genéticos hipervariables, han demostrado ser una de las mejores alternativas para este cultivo. Por este motivo fueron los seleccionados para llevar a cabo el objetivo de la presente investigación, en la cual se busco asociar microsatélites a loci genéticos de proteínas de reserva y de dureza del grano, factores determinantes de la calidad panadera de este cereal. Para llevar a cabo está investigación se seleccionaron 80 genotipos de trigo de pan, a los cuales se les determinó: porcentaje de proteína del grano, volumen de sedimentación, gluten seco, gluten húmedo, gluten índex e índice de dureza. Esta información fue utilizada como base para seleccionar aquellos marcadores genéticos que estuvieran asociados con estos parámetros de calidad. De los seis microsatélites analizados cuatro estuvieron asociados con diferentes pruebas de calidad. El marcador Xglu A3 presentó correlaciones significativas con volumen de sedimentación (0,385), gluten seco (0,394) y gluten índex (0,377). Xgwm 164 se asoció significativamente con sedimentación (0,235) y gluten índex (0,233), el partidor Xgwm 135 presento correlaciones significativas con gluten seco (0,172) y gluten índex (0,221) y el SSR Xgdm 19 fue el marcador con mayor número de pruebas asociadas: porcentaje de proteínas (0,447), sedimentación (0,408), gluten seco (0,487), gluten índex (0,391) e índice de dureza (0,483). De estos cuatro microsatélites, Xglu A3 y Xgdm 19, son los más informativos con índices de polimorfismos (PIC) de 0,721 y 0,758 respectivamente. Ninguno de los SSR estudiados presentó asociación con gluten húmedo. Los marcadores Xgwm 498 y Xgdm 98, no se correlacionaron con ninguno de los parámetros de calidad. Al analizar la distribución de las frecuencia genotipica de los marcadores seleccionados, en los grupos de genotipos de buena, regular y mala calidad panadera, se seleccionó haplotipos promisorios para buena calidad. A todo el germoplasma analizado se le determinó la presencia de secalina, proteína de centeno, la cual existe en algunas líneas de trigo por efecto de translocaciones cromosomales con este cereal. Treinta y tres genotipos dieron positivo para este análisis. La mayoría de este grupo presentó bajos niveles de volumen de sedimentación. Este resultado indica la necesidad de tener presente este factor cuando se están determinando criterios de selección para calidad panadera. Paralelamente, en esta investigación se caracterizó las gluteninas de alto peso molecular, de las 80 líneas y variedades en ensayo. Las subunidades permitieron determinar el índice GLU-1, el que demostró ser un buen indicador de calidad panadera, por su buena asociación con volumen de sedimentación.

Full textFatigue crack growth rate (FCGR) tests in corrosive environments are a challenge for laboratories, where the most used techniques (e.g. Clip Gage and Crack Propagation Sensor) for crack size measurements, deteriorate. Potential Drop (PD) technique is a high precision viable alternative, however, it must be demonstrated that the laboratory has capacity to obtain high precision and accuracy through the method. This study has the main objective of evaluate a methodology to determine the short crack size during fatigue tests to properties chacacterization of materials used as oil gathering pipes in the oil and gas industry in corrosivive environment. The other objectives are: · Consolidate the PD technique for crack size monitoring in short crack SENB specimen configurations; · Introduce the 13Cr5Ni2Mo, 25Cr7Ni and API 5L X60 crack propagation rate curves (da/dN x ΔK) tested in air; · Identify test procedures improvements to enhance precision and accuracy of FGCR test curves. FCGR tests were performed in three different steels, i.e. Supermartensitic, Superduplex and Carbon Steel, where Crack Propagation Sensor (template) and PD technique (evaluated method) data were registered. Equations to determine specimen crack size in function of the potential difference measured transversally to the crack were validated with the Crack Propagation Sensor and FCGR curves in air for the studied materials were presented. A strong correlation between both crack size measurement techniques was observed. It is believed that small differences in measured crack size between techniques are mainly due to: · The tunneling effect in the crack front, both methods measuring the crack in different specimen regions · The imprecisions in the distance of the welding point of the multimeter wires used in PD to the crack. The FCGR curves behavior were similar to the two stage curve in air (R ≥ 0.5) from BS 7910 standard for the most of the curve. However, when ΔK was close to 15 MPa.m1/2 (initial applied ΔK range), the steels presented significantly lower propagation rate compared to the standard curve. It was pointed out possible reasons for this deviation and tests procedures improvements were suggested in order to increase FCGR test precision and accuracy.

Full textThe thin bifacial solar cells are a promising opportunity to reduce costs in manufacturing solar cells. These devices take advantage of solar radiation more efficiently by using the both sides of the solar cell to produce electricity. This study aimed to analyze the type of substrate, n and p, for the manufacture of thin bifacial solar cells with silicon substrate Czochralski (Cz-Si) with a thickness of 130 μm. The wafers, provided by the company Meyer Burger, were obtained by wire cutting process. The evaluation of the influence of texture processing time on the wafer, the diffusion/firing temperature optimization of metallic pastes deposited by screen printing and finally the comparison of the electrical parameters of solar cells with those from thin bifacial manufactured devices obtained by etching were performed. From a standard process of NT-Solar texture etch, two immersion times were tested, 50 min and 60 min, and the former showed the lowest weighted average reflectance and devices with higher short circuit density. The diffusion/firing of Ag and Al metallic pastes have been optimized considering the thermal processing temperature in the range between 850 ? C and 890 ? C. It was observed that the highest average efficiency were between 860 ? C and 870 ? C. The best performance were observed in the cells fabricated with phosphorous emitter in front and boron rear side, i.e., the structure n+np+ and n+pp+, and the efficiencies in front side was 12.8% and 13.6%, respectively and in the rear side 10.4 % and 9.0 %, respectively. By comparing these results with solar cells obtained by similar processes using chemical thinned wafers, the n+np+ structure had 1 % lower efficiency and the n+pp+ one presented similar efficiency values. Regarding the type of substrate, it can be concluded that the solar cells fabricated with the n-type substrate showed higher bifaciality, but the most efficient was manufactured with p-type silicon
As c?lulas solares bifaciais finas representam uma oportunidade promissora para reduzir os custos na fabrica??o de c?lulas solares ao aproveitar a radia??o solar de maneira mais eficiente utilizando as duas faces do dispositivo para produzir energia el?trica. Este trabalho teve como objetivo a an?lise do tipo de base, n e p, para fabrica??o de c?lulas solares bifaciais finas com substrato de sil?cio Czochralski (Si- Cz) com espessura da ordem de 130 μm obtidas ap?s processo de corte a fios e fornecidas pela empresa Meyer Burguer. Foi realizada a avalia??o da influ?ncia do tempo de processo de textura??o, a otimiza??o da temperatura de queima/difus?o das pastas met?licas depositadas por serigrafia e, por fim, a compara??o dos par?metros el?tricos das c?lulas solares com os obtidos em dispositivos bifaciais fabricados em l?minas finas obtidas por ataque qu?mico. A partir de um processo de textura??o padr?o do NT-Solar dois tempos de imers?o foram testados, 50 min e 60 min, sendo que o primeiro produziu a menor reflet?ncia m?dia ponderada e os dispositivos com maior densidade de corrente de curto-circuito. A queima das pastas met?licas de Ag e Al foi otimizada considerando a temperatura do processo t?rmico no intervalo entre 850 ?C e 890 ?C. Observou-se que a maior efici?ncia m?dia se encontra entre 860 ?C e 870 ?C. As c?lulas solares mais eficientes foram as fabricadas com a regi?o frontal dopada com f?sforo e a posterior dopada com boro, isto ?, as estruturas n+np+ e n+pp+ com efici?ncias frontal de 12,8 % e 13,6 %, respectivamente, e efici?ncia posterior de 10,4 % e 9,0 %, respectivamente. Ao comparar estes resultados com c?lulas solares obtidas por processos similares e fabricadas com l?minas de outros fabricantes a estrutura n+np+ apresentou efici?ncia 1 % menor e a estrutura n+pp+ apresentou valores similares. Quanto ao tipo de substrato, as c?lulas solares fabricadas com o tipo n apresentaram melhor bifacialidade, mas as mais eficientes foram as fabricadas com sil?cio tipo p.

This work presents the study and development of a modification proposal of the classical MPPT - P&O approach, based on the utilization of the power and voltage derivatives in PV panel terminals. The contribution of this study consists in the employment of the time derivative of voltage that is used to determine converter duty cycle step size instantly. The proposed MPPT approach when compared to the classical P&O, presents some advantages like as: better dynamic response, steady state error reduction and robustness (considering different irradiation and temperature profiles). In order to validate this study, a microinverter prototype based on flyback converter, using this new approach, was implemented aiming to connect PV panels to the mains. Microinverter control strategy was held on Matlab/Simulink? environment in association to a data processing board (DS1104 from dSPACE?).
Este trabalho apresenta o estudo e o desenvolvimento de uma proposta de modifica??o do m?todo de MPPT P&O cl?ssico com base na utiliza??o da derivada da pot?ncia e da derivada da tens?o nos terminais dos pain?is PV. A contribui??o deste trabalho consiste no emprego da derivada da tens?o dos pain?is, a qual ? utilizada para determinar a varia??o instant?nea do ciclo de trabalho do conversor. O m?todo de MPPT proposto em compara??o com o m?todo P&O convencional apresentou melhor desempenho considerando-se a resposta din?mica, o erro de estado estacion?rio e a robustez (contra diferentes perfis de irradi?ncia e de temperatura). A fim de validar este estudo, um prot?tipo de um microinversor com base no conversor flyback, usando a abordagem proposta, foi implementado com o objetivo de conectar pain?is fotovoltaicos ? rede el?trica. A estrat?gia de controle do microinversor foi realizada em ambiente Matlab/Simulink? em associa??o a uma placa de processamento de dados (DS1104 da dSPACE?).

RESUMO Os principais objetivos deste estudo s?o a investiga??o do campo da webometria, definindo o lugar que esta ocupa dentro da Ci?ncia da Informa??o e o seu inter-relacionamento com os tradicionais campos das m?tricas (bibliometria, cientometria e informetria), assim como a an?lise dos fluxos da informa??o na Web, mediante a aplica??o de diferentes indicadores webom?tricos aos s?tios dos centros filiados ao Conselho Latino-Americano de Ci?ncias Sociais (CLACSO). Os indicadores webom?tricos utilizados s?o: Tamanho do S?tio, Visibilidade, Luminosidade, Fator de Impacto Web, Densidade por Link e Densidade da Rede. O foco de an?lise ? o estudo dos links enquanto fontes de informa??o e como instrumentos de conex?o que influenciam e s?o influenciados pelos v?nculos acad?micos neste ambiente. Para a extra??o, quantifica??o e representa??o gr?fica dos dados s?o utilizados motores de busca (Google, Yahoo e Alta Vista), programas mapeadores (Xenu Link Steuth) e programas de an?lise e visualiza??o de redes (Ucinet 5 e Netdraw). Os resultados obtidos indicam que a informetria deve ser entendida como o campo maior que compreende n?o s? a bibliometria e a cientometria, mas tamb?m campos emergentes como a cibermetria e a webometria. Apresenta-se a posi??o de que a webometria n?o est? totalmente absorvida pela bibliometria, j? que a informa??o no meio digital n?o pode ser considerada como informa??o ?registrada? e sim como ?dispon?vel? em meio eletr?nico, havendo a necessidade de uma maior reflex?o te?rica para abrigar novos conceitos que surgem com a influ?ncia das inova??es tecnol?gicas no pensar e no fazer da Ci?ncia da Informa??o. A aplica??o dos indicadores webom?tricos demonstra que o Fator de Impacto da Web e Densidade por Link n?o oferecem resultados satisfat?rios. J? os demais indicadores demonstram sua utilidade e relev?ncia na mensura??o dos dados coletados na Web e nos processos de identifica??o e an?lise dos padr?es do fluxo da informa??o e inter- relacionamento entre institui??es acad?micas dentro do mundo virtual. O estudo demonstra tamb?m que a maioria dos s?tios latino-americanos de ci?ncias sociais estabelece poucas rela??es com outros centros do mesmo pa?s e de outros paises da regi?o na Web, o que se traduz em uma densidade de rede em geral bastante baixa e deixa em evid?ncia o importante potencial de conectividade a ser explorado no futuro pelo CLACSO e pelos seus centros membros. ABSTRACT: The main propose of this study is to research the field of webometrics, and define its role within Information Science and its relation with traditional metric fields (bibliometrics, scientometrics and informetrics). Also, by applying different webometric indicators to the sites of centers affiliated to the Latin American Council of Social Sciences (CLACSO), this study analyzes the information flows that occur inside the Web. The webometric indicators utilized are: Site Size, Visibility, Luminosity, Web Impact Factor, Link Density and Network Density. The analysis focuses mainly on an examination of links. These are regarded as sources of information and as instruments of connection that influence scholarly relationships within this virtual environment, at the same time being influenced by those relationships. Search engines such as Google, Yahoo and Alta Vista, link checking software such as Xenu Link Steuth, and programs for analysis and visualization of large networks such as Ucinet 5 and Netdraw are utilized for data collection, quantification and graphic representation of data. The results obtained indicate that infometrics has to be understood as a large field to include not only bibliometrics and scientometrics, but also emergent fields such as cybermetrics and webometrics. According to this research, webometrics should not be completely absorbed by bibliometrics, because the information in this digital environment cannot be considered as ?recorded.? Instead, this information should be seen as ?available? in electronic support. Therefore, it is necessary to think about a broader theoretical framework that allows us to include the new concepts that come out with the influence of technological innovations on the thinking and the makings of Information Science. The application of webometric indicators demonstrates that Link Density and the Web Impact Factor are insufficient. On the other hand, the other indicators stand out as useful, and are relevant tools to the measurement of data collected in the Web, as well as to the processes of information flows and to the interrelation among scholarly institutions inside the virtual world. This study also demonstrates that most of Latin American social sciences websites establish very few connections with the websites of other centers of the same country or region, which is reflected on a relatively low Network Density and emphasizes the enormous potential of connectivity as an area to be developed in the future by CLACSO and its member centers

Full textA presente disserta??o, vinculada ? linha de pesquisa Criminologia e Controle Social, do Programa de P?s-Gradua??o em Ci?ncias Criminais, da Faculdade de Direito da Pontif?cia Universidade Cat?lica do Rio Grande do Sul, tem por finalidade o estudo da Interna??o Psiqui?trica, perpassando desde as quest?es civis e psicossociais da capacidade e da autonomia do sujeito, at? aspectos jur?dicos e sociais. O trabalho defende, ainda, um elo entre o profissional da sa?de mental e seu paciente, com o objetivo final de se criar um ambiente terap?utico apropriado para um tratamento psiqui?trico eficaz. Desse modo, visa ? obten??o de resultados ?teis para o paciente, familiares e, em ?ltima an?lise, para a pr?pria sociedade, como uma forma de resposta social aos anseios populares calcados num (falso) Estado Democr?tico de Direito. No mesmo sentido, em que pese a ocorr?ncia de mudan?as, o tratamento hospitalar ainda n?o se mostra suficiente, na medida em que o ex-internado sai do hospital psiqui?trico com um estigma, criado pela pr?pria sociedade, que o identifica como um desigual perante os demais. Isso demonstra que o problema ?, antes de tudo, cultural. Por fim, a quest?o da interna??o psiqui?trica pode exceder os limites estabelecidos pela Medicina e pelo Direito, situa??o essa que pode ser traduzida como um abuso de meios m?dicos ou de respons?veis legais pelo paciente, com o fim de alcan?ar uma finalidade n?o autorizada pela lei. Desta forma, tal abuso pode ser verificado quando, pelo contexto da interna??o, ocorrer situa??es-tipo, que se caracterizam como il?citos penais, como o c?rcere privado e o constrangimento ilegal. Em ?ltima an?lise, o trabalho evidencia que o enfermo (inimput?vel ou semi-imput?vel, com necessidade de tratamento terap?utico) ? um sujeito cujos direitos constitucionalmente garantidos devem prevalecer acima de quaisquer interesses privados ou econ?micos.

Full textThe innovation theme is becoming more widespread and disseminated globally, which in one hand is beneficial for their popularization and demystification, but on another hand runs the risk of becoming a rhetoric and superficial reference. On this given scenario, several definitions arise and the innovation concept goes beyond the purely technological barrier products and processes to aggregate marketing and some others organizational aspects. However, innovation promotion agencies still have issues on identify what is or is not innovation. That can be explained due to the lack of structured processes of analysis that enable safer proposals or projects evaluation involving innovation opportunities. On that context, the present work has as main objective to propose an analysis process to give support to a potential innovation characterization, identifying whether it is an innovation opportunity and at which typology it mainly fits. This is an applied and exploratory research. The used method was literature research and field testing as a technique with 15 experts on the subject, with primarily qualitative approach. Among the main results can be cited the analysis proposal process to sustain the innovation characterization and distinction of its typology, comprising three analysis blocks; and the contribution to define the innovation type in frontier areas. However, there was still identified a convergence difficulties, even among experts, for some cases evaluated, which opens an opportunity for further research on the topic. These cases are also described on this present work.

Full textThis dissertation presents the development and evaluation of a prototype for the stimulus of the olfactory system, which will be employed in the study of neuroimages gathered by functional magnetic resonance image (fRMI). Basic requirements for the prototype include: safety, human physiology and environmental compatibility, homogeneous release of aerosolized stimuli, accurate control of pressure and flow conditions, support for up to three distinct substances, and substance mixing capability. Digital image processing techniques were used in evaluation process through the usage of Matlab in order to better assess the reliability and reproducibility in the evaluation of the of the samples released under controlled constant pressure of 3.5+/- 0.3 kgf/cm?, different flows (4 l/min, 6 l/min, 8 l/min and 10 l/min), and different duration periods (10s, 15s, 20s, 30s, 60s and 90s). Charts with the image profiles, histograms and statistical data were generated and analyzed. The delay in the system, important information for any study in fRMI, was measured using an oxygen sensor and custom software solution. Experiments for the determination of the amount of substance required and the real capability of mixing substances were performed with parameters based on the results from the digital image processing analysis.
Esta disserta??o de mestrado apresenta o desenvolvimento e a avalia??o de um prot?tipo para estimular o sistema olfativo, o qual ser? empregado em estudos de neuroimagens obtidas pela modalidade de resson?ncia magn?tica funcional. Para o desenvolvimento do prot?tipo foram definidos requisitos b?sicos que o sistema deveria possuir: seguran?a, compatibilidade com o ambiente e com as caracter?sticas fisiol?gicas humanas, dispensar amostra aerossolizada, precis?o para controlar e regular vaz?o e press?o, capacidade para tr?s subst?ncias distintas e possibilidade de mistur?-las. A avalia??o utilizou t?cnicas de processamento de imagens digitais com a utiliza??o do software Matlab com a finalidade de estudar a confiabilidade e reprodutibilidade na quantifica??o da amostra dispensada utilizando press?o fixa de 3,5 +/- 0,3 kgf/cm? e as vari?veis fluxo (4 l/min, 6 l/min, 8 l/min e 10 l/min) e tempo (10s, 15s, 20s, 30s, 60s e 90s). Os resultados foram analisados atrav?s de gr?ficos de perfil dos pixels, histogramas e dados estat?sticos das imagens. O atraso do sistema, dado fundamental para pesquisas em resson?ncia magn?tica funcional, foi medido com a utiliza??o de um sensor de oxig?nio e um software desenvolvido em LabVIEW. Experimentos para medir o consumo e a possibilidade de misturar as amostras foram realizados utilizando os resultados obtidos com a valida??o por processamento de imagens digitais.

Full textAs simula??es de Monte Carlo v?m sendo utilizadas para validar m?todos de corre??o de atenua??o e espalhamento em SPECT. O acoplamento ? simula??o de um phantom matem?tico como o NCAT, com movimentos respirat?rios e batimentos card?acos, permite uma modelagem ainda mais adequada e realista das aquisi??es em Medicina Nuclear. Este trabalho busca avaliar a influ?ncia da resolu??o espacial dos mapas de coeficientes de atenua??o na reconstru??o quantitativa em SPECT card?aco. O estudo baseia-se em diversas simula??es de Monte Carlo de imagens de SPECT, com ?nfase especial no phantom matem?tico NCAT 4D (4D NURBSbased Cardiac Torso) e avalia o efeito da varia??o da resolu??o espacial dos mapas de atenua??o n?o-uniformes utilizados na corre??o de atenua??o. A an?lise visual das imagens simuladas reconstru?das revelou que a falta de corre??o de atenua??o criou uma dispers?o das contagens ao redor do mioc?rdio e do f?gado. Nas imagens corrigidas para a atenua??o, esse efeito de borramento foi substitu?do pela uniformiza??o da atividade nas paredes do mioc?rdio, tanto na parede anterior como da parede posterior. Observou-se tamb?m um aumento de contraste quantitativo e qualitativo com a aplica??o da corre??o de atenua??o. O principal fator degradador do diagn?stico de perfus?o mioc?rdica em SPECT foi a presen?a de tecido atenuador ao redor e nas proximidades do cora??o, particularmente pr?ximo ao f?gado. A aplica??o do m?todo de corre??o de atenua??o nas imagens de perfus?o mioc?rdica em SPECT revelou-se significante para a melhoria da qualidade das imagens reconstru?das. Os resultados dos perfis de contagem mostram que, mesmo do caso de borramento severo dos mapas de coeficiente de atenua??o, n?o existe mudan?a significativa na quantifica??o das paredes do mioc?rdio, tanto com rela??o ? intensidade quanto ao contraste entre as paredes e a cavidade. Observa-se tamb?m que a utiliza??o dos mapas de atenua??o de baixa resolu??o espacial na corre??o n?o provoca o surgimento de artefatos e de componentes de alta freq??ncia, suavizando a imagem reconstru?da.

Esta estrat?gia ? denominada Controlador Proporcional, Senoidal e Cossenoidal (PSC). Os ganhos deste controlador s?o obtidos atrav?s de t?cnicas de otimiza??o convexa baseadas na formula??o LMI (Linear Matrix Inequality). Atrav?s destas t?cnicas, determina-se um controlador do tipo realimenta??o de estados tal que os p?los em malha fechada do sistema estejam contidos em uma especificada regi?o no plano s, al?m de minimizar um limitante superior da norma H do sistema, de forma a minimizar a influ?ncia de dist?rbios da carga na tens?o de sa?da da UPS. Uma UPS comercial, controlada atrav?s de um Controlador PID (Proporcional, Integral e Derivativo), ? apresentada neste trabalho, bem como, seus testes de desempenho mediante carga linear e n?o-linear. Por fim, troca-se a a??o do Controlador PID pela estrat?gia alternativa proposta (Controlador PSC) e realizam-se novas simula??es e novos testes. Observa-se em todos os resultados apresentados, tanto simulados quanto pr?ticos, uma melhora bastante significativa devido ? utiliza??o do Controlador PSC, sem acr?scimo de custo no hardware utilizado comercialmente. Com isto, confirma-se a viabilidade da utiliza??o desta estrat?gia de controle em UPS comerciais.

Full textThe world we live today is very dependent of the technology advance and the Systemson- Chip (SoC) are one of the most important actors of this advance. As a consequence, the Moore's law has been outperformed due to this strong demand on the SoCs for growth, so that new silicon technologies has emerged along with new fault models that decreased the reliability of these devices. SoCs built using Very Deep Sub-Micron technology have a great number of interconnections, increasing the occurrence of Resistive-Open defects that occur on these interconnections up to the point where Resistive-Open defects have become the most important responsible for defective SoCs escaping the manufacturing tests. According to SIA Roadmap's projection, the area consumed by the SRAM on the SoC will be around 95% of the available area, knowing these memory have a great number of interconnections there is also a great probability of occurring Resistive-Open defects on the SRAM circuits which will compromise the overall SoC reliability. When found on SRAMs cells, these defects are able to cause dynamic and static functional faults according to its size, where static faults are sensitized by performing only one operation at the SRAM cell, while dynamic are sensitized by two or more operations. The most common manufacturing tests used to detect defective SoCs are today unable to detect dynamic faults caused by weak Resistive-Open defects. March test performs access on the memory with the intention of sensitizing the faults and detect them as consequence. Due to the higher number of operations necessary to sensitize dynamics faults, this test is not able to detect them properly. Another test is the Iddq test, which is able to detect the presence of defects by monitoring the overall current consumption of a SoC while it's being excited by a known vector of data on its inputs. The consumed current is compared to thresholds or to another similar device that is being excited on the same way. Iddq test is not able to distinguish the variations on current caused by process variations or defects presence. There is an other type of test using On-Chip Current Sensors (OCCS) with March tests that performs current monitoring on the circuits of the SoC and compare them with a threshold in order to set a ag when the monitored current gets higher or lower than a con gured thresholds. Because the mentioned test uses threshold, it is not able to detect Resistive-Open defects that could happen in any node, with any size, in the SRAM cell performing any operation. In this scenario the current consumption could be higher or lower than the defectless current consumption of a cell, making impossible to detect defects using thresholds. By all that, the objective of this dissertation is to propose a defect detection technique able to overcome the three mentioned limitations of preview explained tests. For that, OCCS are along with March test, but a Neighborhood Comparator Logic (NCL) has been included with the objective to perform the detections itself, removing from the OCCS the mission of nding defects. Now the OCCS is only responsible in converting the monitored current consumption signal to a one bit PWM digital signal. In this form, no threshold will be required because the NCL will obtain the reference of the correct current consumption (behavior reference) within the SRAM circuits, by comparing the neighboring cells and adopting the most common behavior as the reference one, so that it will detect those cells that behave di erently from the reference as defective ones. The neighborhood's cells are excited in a parallel form by the test processor, which performs a March test algorithm. The NCL, the OCCS and the March test, together, compose the proposed Resistive-Open detection technique, which has been validated on this work. As result, the proposed technique has shown being able to detect all of the 10 million defective cells of a 1Gbit SRAM containing the hardest defect to detect (small ones). No defective cell has escaped the simulated test and there was only 294,890 good cells being wasted, which represents 0.029% of the simulated SRAM cells. All of that, by costing only the equivalent to the area of 56 SRAM cells per monitored column and a manufacturing test that performs 5 operations per line of the SRAM.
O mundo de hoje ? cada vez mais dependente dos avan?os tecnol?gicos sendo os sistemas em chip (SoC, do ingl?s System-on-Chip) um dos principais alicerces desse avan?o. Para tanto que a lei de Moore, que previu que a capacidade computacional dos SoCs dobraria a cada ano, j? foi ultrapassada. Devido a essa forte demanda por crescimento novas tecnologias surgiram e junto novos modelos de falhas passaram a afetar a con abilidade dos SoCs. Os SoCs produzidos nas tecnologias mais avan?adas (VDSM - Very Deep Sub-Micron), devido a sua alta integra??o de transistores em uma ?rea pequena, passaram a apresentar um grande n?mero de interconex?es fazendo com que os defeitos do tipo Resistive-Open, que ocorrem nessas interconex?es, se tornassem os maiores respons?veis por SoCs com defeitos escaparem os testes de manufaturas. Ainda, segundo proje??es da SIA Roadmap, a ?rea consumida pela SRAM ser? em torno de 95% da ?rea utilizada por um SoC. E sabendo que essas mem?rias possuem in?meras interconex?es, existe uma grande probabilidade de ocorrer defeitos do tipo Resistive-Open em seus circuitos. Esses defeitos s?o capazes de causar falhas funcionais do tipo est?ticas ou din?micas, de acordo com a sua intensidade. As falhas est?ticas s?o sensibilizadas com apenas uma opera??o e as din?micas necessitam de duas ou mais opera??es para que sejam sensibilizadas. Os testes de manufatura mais utilizados para aferir a sa?de dos SoCs durante o processo de manufatura s?o hoje ine cientes frente aos defeitos do tipo Resistive-Open. O mais comum deles ? o March Test, que efetua opera??es de escrita e leitura na mem?ria com o objetivo de sensibilizar falhas e por m detect?-las, entretanto ? ine ciente para detectar as falhas do tipo din?micas porque ? necess?rio efetuar mais opera??es que o tempo dispon?vel permite para que essas falhas sejam sensibilizadas. Outro teste utilizado durante a manufatura chama-se teste de corrente quiescente (teste de Iddq), este monitora a corrente consumida do SoC como um todo durante a inje??o de vetores nos sinais de entrada, o consumo de corrente do chip ? comparado com limiares ou outro chip id?ntico sob o mesmo teste para detectar defeitos, entretanto n?o ? poss?vel distinguir entre varia??es inseridas, nos sinais monitorados, pelos defeitos ou pelos corners, que s?o varia??es nas caracter?sticas dos transistores fruto do processo de manufatura. E, por m, o ?ltimo teste que ? apresentado ? uma mistura dos dois testes anteriores, utiliza sensores de correntes e algoritmos de opera??es como em March Test onde que o defeito ? detectado pelos sensores de corrente embutidos quando a corrente monitorada ultrapassa dado limiar, embora esse teste tenha condi??es de detectar defeitos que causam falhas din?micas e de n?o sofrerem in u?ncia dos corners, ele ? ine caz ao detectar defeitos do tipo Resistive-Open que possam ocorrer em qualquer local, com qualquer tamanho de imped?ncia em uma SRAM executando qualquer opera??o, porque os defeitos do tipo Resistive-Open ora aumentam o consumo de corrente e ora o diminui de acordo com essas tr?s caracter?sticas citadas. Compara??es por limiares n?o t?m condi??es de contornar esta di culdade. Com tudo isso, o objetivo desta disserta??o de mestrado ? propor uma t?cnica de detec ??o de defeitos que seja capaz de vencer as tr?s limita??es dos testes convencionais de manufatura apontadas. Para a tarefa, sensores de corrente s?o utilizados associadamente com March Test, entretanto com o acr?scimo de uma L?gica Comparadora de Vizinhan?a (LCV) que tomar? para si a fun??o de detectar defeitos, deixando os sensores apenas encarregados em transformar a corrente anal?gica em um sinal digital e que tem a capacidade de eliminar a necessidade do uso de limiares, junto com as demais limita??es apontadas. A LCV monitora o comportamento de uma vizinhan?a c?lulas e, comparando-os entre si, acusa aquela ou aquelas c?lulas que se comportarem diferentemente das suas vizinhas como defeituosas, desta maneira a refer?ncia de comportamento correto ? obtida da pr?- pria vizinhan?a durante a execu??o do teste de manufatura, eliminando a necessidade de conhecimento pr?vio do tipo de dist?rbio causado pelos defeitos do tipo Resistive-Open, trazendo facilidade na hora de projetar o sistema de detec??o de defeitos e adicionado o poder de detectar qualquer defeito que gere altera??es no sinal de corrente consumida das c?lulas da SRAM. Neste contexto, o sensor de corrente tem apenas a fun??o de gerar o sinal digital, que ? de 1 bit para cada sinal monitorado (V dd e Gnd) e modulado em largura de pulso (PWM), assim a LCV tamb?m tem sua complexidade diminu?da, pois ? constitu?da por apenas portas l?gicas. A LCV e os sensores de corrente s?o utilizados durante o teste de manufatura, as compara??es que ocorrem na vizinhan?a s?o efetuadas paralelamente nas c?lulas da mem ?ria, ent?o o teste de manufatura necessita efetuar opera??es de acesso para excitar semelhantemente todas as c?lulas que participam da mesma vizinhan?a. O March Test ? um teste que efetua opera??es desta natureza e, portanto, ? utilizado para controlar a execu??o do teste e recolher os dados proveniente da LCV, que cont?m o resultado da detec??o efetuada em cada vizinhan?a. A LCV, o sensor de corrente e o March Test juntos comp?em a t?cnica de detec??o de defeitos proposta nesta disserta??o, e foram validados quanto as suas fun??es para comprovar que operam como projetados. Por m, a t?cnica proposta se mostrou capaz de detectar as 10 milh?es de c?lulas defeituosas (com o defeito mais dif?cil de detectar que causa falha funcional din?mica) em uma SRAM de 1Gbit, sem deixar passar nenhuma c?lula defeituosa pelo teste de manufatura, junto a isso, 294.890 c?lulas boas foram desperdi?adas, isto-?, foram dadas como defeituosas enquanto n?o tinham defeitos, o que representa apenas 0,029% de desperd?cio. Tudo isso, ao custo de ?rea equivalente a ?rea consumida por 56 c?lulas de mem?ria, por coluna monitorada, e ao custo de um teste de manufatura que executa apenas 5 opera??es em cada linha da SRAM.

Background: Bariatric surgery patients are counseled to change their lifestyle behaviors. It is reasonable to presume that, by sharing the same environment, the child will be exposed to a healthier environment. Objective: To compare phenotypic and behavioral characteristics between children born to obese mothers before (BMS) or after (AMS) bariatric surgery. Methods: This retrospective cohort study made comparisons between these two groups regarding phenotyping and behavioral data. Results: The sample consisted of 101 participants aged 0 - 12 years, 67 BMS and 34 AMS. All were predominantly sedentary and reported eating an excess of total energy above estimated needs, with no difference between groups (BMS median = 569 kcal, IQR = 1,185; AMS median = 245 kcal, IQR = 1,055; P =.18). Consequently, there was a high prevalence of overweight (Percentile ? 85) in both groups (BMS N = 40, 59.7%; AMS N = 18, 52.9%, P = .52), as well as elevated abdominal and arm circumferences. Additionally, children in both groups reported a deficit in daily calcium intake. Conclusions: Despite mothers? guidance for lifestyle changes after bariatric surgery, the children in our sample reported multiple obesogenic environmental conditions, such as poor behavioral characteristics and, high prevalence of overweight.
Introdu??o: Os pacientes submetidos ? cirurgia bari?trica s?o aconselhados e recebem orienta??es para mudar seus comportamentos de estilo de vida. ? razo?vel presumir que, dividindo o mesmo ambiente, a crian?a vai estar exposta a um ambiente familiar mais saud?vel. Objetivo: Comparar comportamentos das crian?as em rela??o a sua dieta e atividade f?sica para avaliar desfechos fenot?picos entre crian?as que nasceram antes da cirurgia materna (ACM) e depois da cirurgia materna (DCM) e verificar se o procedimento de perda de peso da m?e mudou comportamento da crian?a. Metodologia: Este estudo de coorte retrospectiva realizou compara??es entre os grupos ACM e DCM a respeito de dados antropom?tricos, alimentares e de atividade f?sica. Resultados: A amostra consistiu em 101 participantes com idades entre 0 e 12 anos, N = 67 ACM e N = 34 DCM. Todos eram predominantemente sedent?rios e reportaram ingerir um excesso de energia total acima das necessidades nutricionais recomendadas para a idade e g?nero baseadas nas refer?ncias de ingest?o diet?ticas (Dietary Reference Intakes, DRIs), sem diferen?a entre os grupos (ACM mediana = 569 kcal, AIQ = 1.185; DCM mediana = 245 kcal, AIQ = 1.055, P = 0,18). Consequentemente, observou-se uma alta preval?ncia de excesso de peso (Percentil ? 85) em ambos os grupos (ACM N = 40, 59,7%; DCM N = 18, 52,9%, P = 0,52), bem como elevadas circunfer?ncias abdominal e do bra?o. Conclus?o: Apesar das orienta??es ? m?e quanto as mudan?as necess?rias de estilo de vida ap?s a cirurgia bari?trica, os dados de nossa amostra relataram m?ltiplas condi??es obesog?nicas no ambiente familiar das crian?as, como pobres caracter?sticas comportamentais e, consequentemente, alta preval?ncia de excesso de peso.

Poucos estudos analisaram a diversidade genética de HTLV em Salvador que têm características sócio-demográficas similares a algumas cidades africanas e apresenta a mais elevada prevalência para o HTLV-I (1,35%) em doadores de sangue do Brasil. Nós investigamos a real prevalência nesta população, 1,76% (23/1385). As taxas de infecção foram 1,2% e 2,0% para homens e mulheres, respectivamente, que aumentou com a idade. Quando nós analisamos uma coorte constituída por gestantes, encontramos uma freqüência de 0,9% (57 de 6754). Através de análise filogenética de parte do gene LTR virai, nós investigamos na população geral, gestantes, indivíduos com HAM/TSP e UDIs os subtipos de HTLV-I circulantes em Salvador. Demonstramos que a maioria das amostras pertence ao grupo da América Latina, subgrupo A (subtipo a). RFLP de fragmentos gênicos da globina p em 34 destes indivíduos demonstrou que 29.4% dos cromossomos são do haplótipo tipo CAR (Banto), sugerindo que Salvador recebeu também africanos do sul da África durante o tráfico de escravos. Assim, nossos resultados corroboram as hipóteses de múltiplas introduções pós- Colombianas do subgrupo A em Salvador. Nós também analisamos o polimorfismo do HTLV-ll em UDIs de Salvador e demonstramos que a maioria deles está relacionada à variante molecular Brasileira do subtipo lia. Assim, demonstramos pela primeira vez no Brasil a presença de um subtipo 11a, de UDIs, relacionado aos isolados 11a da América do Norte/Europa. Para investigar aspectos da epidemiología molecular das infecções causadas pelos HTLV-1, HTLV- II, e HlV-1 em populações indígenas brasileiras, testamos 683 e 321 soros de índios das tribos Tiriyo e Waiampi, respectivamente. As infecções pelo HIV-1 e HTLV-ll foram detectadas com prevalências muito baixas entre os Tiriyos, enquanto somente HTLV-I estava presente, com baixa prevalência, entre o Waiampis. Análise filogenética do gene env do HTLV-ll isolado dos Tiriyos mostrou que estas seqüências se agrupam mais próximas dos isolados de HTLV-ll de UDIs que vivem em áreas urbanas do sul do Brasil, do que aos isolados da tribo Kayapo. Isto confirma que a maioria das cepas brasileiras de HTLV-lia compreende um grupo filogenético com um considerável grau de diversidade.
Few studies have analyzed the genetic diversity of HTLV in Salvador that have sociodemographic characteristics similar to some African cities and presents the highest HTLV-I prevalence rate (1.35%) of the Brazil. We investigated the real HTLV-1 prevalence in the Salvador population and demonstrated the overall prevalence of 1.76% (23/1385). The Infection rates were respectively 1.2% and 2.0% for males and females. Specific seroprevalence shows a trend with increasing age. When we analyzed the pregnant women cohort, we found a frequency relatively high (57 of 6754 women). We also studied in other cohort the circulating HTLV-1 strains in Salvador and the phylogenetic analysis from part of the LTR fragments showed that most of the samples belongs to the Latin American cluster of the subgroup A (subtype a). The p-globin RFLP in 34 of these individuals demonstrated that 29,4% of the chromosomes are CAR-haplotype (Bantu) suggesting that Salvador also received slaves from South Africa in the Atlantic slave trade. In addition, our results support the hypotheses of multiple post- Colombian introductions of African HTLV-la strains in Salvador. We also analyzed the HTLV-11 polymorphism in IDUs from Salvador and demonstrated that the majority of them are related to the subtype I la Brazilian molecular variant. Interestingly, we demonstrated for the first time in Brazil the presence of a subtype lla, from IDUs, closely related to the isolates from North America/Europe. To investigate serological, epidemiological and molecular aspects of HTLV-1, HTLV- II, and HIV-1 infections in Amerindian populations in Brazil, we tested 683 and 321 sera from Tiriyo and Waiampi Indians respectively. Both HIV-1 and HTLV-11 infections were detected in very low prevalences among the Tiriyos while only HTLV-1 was present among the Waiampis, also in low prevalence. Phylogenetic analyze of HTLV-ll-env gene from Tiriyo Indians showed that these sequences cluster closer to HTLV-II isolates from IDUs living in urban areas of Southern Brazil than the isolates from another Brazilian tribe, the Kayapos. Our results confirm that most of the HTLV-1 la Brazilian strains comprise a phylogenetic group harboring a considerable degree of diversity.

Full textThe mucopolysaccharidoses present a progressive natural course caused by defects on glycosaminoglycan degradation pathways. Usually severe, the mucopolysaccharidoses considerably shorten patient lifespan. Although in many cases the cognitive function is preserved, considerable neurological morbidity can be present due to spinal cord compression which is secondary to glycosaminoglycan storage in the meninges. Treatment for this complication usually requires surgical intervention with cervical laminectomy for thickened meninges removal. Enzyme replacement therapy used for the treatment of mucopolysaccharidoses reduces lysosomal storage and ameliorates many somatic symptoms but does not provide any direct benefit to central nervous system as the enzyme does not cross the blood-brain-barrier. Due to this limitation of intravenous enzyme replacement therapy some researchers have been working with an alternative option of enzyme delivery with direct action on central nervous system through the extensive close contact provided by cefalo-spinal fluid and meniniges and arachnoid villosities, to the treatment of some lysosomal disorders. Animal model studies have been conducted and some promising results have been achieved. This study intends to present an alternative route for the administration of a recombinant enzyme, directly in the cefalo-spinal fluid, which was used in two patients with mucopolysaccharidosis I and one patient with mucopolysaccharidois VI. These patients gained access to this therapy by individual compassionate use enrollment approved by local Ethics Board at Hospital de Clínicas de Porto Alegre. So far, only animal model trials had been conducted with the use of this administration route in lysosomal storage diseases, and these were the first three patients with mucopolysaccharidoses and cord compression to receive intrathecal enzyme replacement therapy in the world. In 2005, an adult mucopolysaccharidosis I patient presenting cervical cord compression was enrolled in a compassionate use trial of intrathecal enzyme replacement therapy, at the Hospital de Clínicas de Porto Alegre. In 2006, a girl with mucopolysaccharidosis I presenting spinal cord compression was also enrolled in a compassionate use trial of intrathecal enzyme replacement therapy, at the Hospital de Clínicas de Porto Alegre. In 2007, a boy with mucopolysaccharidosis VI and cord compression was enrolled in compassionate use trial of intrathecal enzyme replacement therapy in the same hospital.

Objectives: Identifying, among the instruments Nursing Activities Score (NAS), Therapeutic Intervention Scoring System-28 (TISS-28), and Nine Equivalents of Nursing Manpower Use Score (NEMS), what best reflects nursing workload in a pediatric intensive care unit (PICU) and size up nursing human resources with this score; characterize the patients admitted to the PICU according to clinical and personal data; categorize and analyze the care-related items, grouped, in basic activities and therapeutic interventions; verify the correlation and concordance between the instruments and the influence of companion and case severity on nursing workload. Methods: Observational prospective cohort study with a quantitative approach conducted at the PICU in the S?o Lucas Hospital of the Pontifical Catholic University of Rio Grande do Sul (PUCRS). The sample consisted of all children admitted to the PICU from June 1, 2011, to June 31, 2012. For patient characterization, clinical and personal data were collected and the score Paediatric Index of Mortality 2 (PIM 2) was determined. In order to assess nursing workload, the instruments TISS-28, NEMS, and NAS were used, converted into working hours. Also, these scores were stratified into two groups, in Group 1 the items that comprise the category basic activities were gathered; and Group 2 gathered the items that comprise the other categories of ventilatory, cardiovascular, renal, neurological, and metabolic support, and specific interventions. Companion?s presence was assessed by work shift and then computed in 24-hour care. Data analysis was based on descriptive statistics, Student?s t-test, or ANOVA, Pearson?s correlation, simple linear regression, and the Bland and Altman model. Mortality was analyzed through the Standardized Mortality Ratio (SMR) and the Area Under Curve Receiver Operating Characteristic (AUROC) was used. The nursing personnel was sized up having a resolution from the Brazilian Federal Nursing Council (COFEN) as a basis. Results: The sample consisted of 490 hospitalizations, which totaled 4,617 observations. As for children characterization, 53% were men and there was predominance of infants and preschoolers, 39% were under 1 year of age, and 28% were in the age group between 1 and 5 years old. Regarding the origin, 44% came from the surgical center, 21% from the emergency room, 20% from a hospital ward and 16% from another hospital. Many children had more than one organ dysfunction during hospitalization, highlighting the fact that 61% had respiratory dysfunction. When assessing the average working hours of the nursing team estimated by the scores, we observed that the instrument NAS measured 13.6 hours and it was statistically superior, compared to TISS-28 and NEMS ? 11.7 and 12.9 hours, respectively. In the analysis of average working hours stratified in the groups, we found that in Group 1 the NAS measured 10.2?2.5 hours, standing out in this assessment; however, when considering Group 2, the TISS-28 estimated 6.3?3.1 hours, standing out among the instruments. Good correlations were found between NAS and TISS-28, NAS (2) and TISS-28 (2), NAS (2) and NEMS (2), NEMS and TISS-28, and NEMS (2) and TISS-28 (2). When analyzing concordance using the Bland and Altman method, we observed that TISS-28 and NEMS were the instruments that showed graphically the best concordance. According to the NAS average value, nursing workload was higher with children from the emergency service (14.15?3.89 hours), without companion (14.13?2.42 hours), and there was a tendency to increase the workload as the amount of organ dysfunction increases. The NAS also proved to be effective to estimate case severity, revealing on the day of admission an adequate capacity to discriminate mortality [AUROC of 0.811 (CI 95% 0.726-0.896)], and compared to IMP 2 [AUROC of 0.813 (CI 95% 0.716-0.910)]. Personnel sizing using the workload estimated by the NAS found out the need of 36 nursing professionals to work in this unit. Conclusion: The NAS showed to be the instrument that best measured nursing workload and, using the hours estimated through this score, it was possible to size up nursing human resources at the PICU. As for the characterization of children admitted to the PICU within the study period, there was predominance of men, infants under 1 year of age, and children from the surgical center. This study grouped the items that comprise the instruments NAS, TISS-28, and NEMS, separating the category basic activities from the other categories of therapeutic interventions. The NAS stood out in Group 1 in the category basic activities and TISS-28 in Group 2, which gathered the other categories. The instruments TISS-28 and NEMS were those showing the best correlation and concordance. Through the analyses of total mean workloads, the NAS stood out to estimate the demand for nursing work in this hospital unit. There was an increased nursing workload when the child was without her/his companion. The NAS showed capacity to discriminate mortality and assess case severity.
Objetivos: Identificar, dentre os instrumentos Nursing Activities Score (NAS), Therapeutic Intervention Scoring System-28 (TISS-28) e Nine Equivalents of Nursing Manpower Use Score (NEMS), qual melhor reflete a carga de trabalho de enfermagem em uma unidade de terapia intensiva pedi?trica (UTIP) e dimensionar os recursos humanos de enfermagem com esse escore; caracterizar os pacientes internados na UTIP segundo os dados cl?nicos e pessoais; categorizar e analisar os itens de cuidados, agrupados, em atividades b?sicas e interven??es terap?uticas; verificar a correla??o e a concord?ncia entre os instrumentos e a influ?ncia do acompanhante e da gravidade do caso na carga de trabalho de enfermagem. M?todos: Estudo de coorte prospectivo observacional com abordagem quantitativa realizado na UTIP do Hospital S?o Lucas da Pontif?cia Universidade Cat?lica do Rio Grande do Sul (PUCRS). A amostra consistiu em todas as crian?as internadas na UTIP de 1? de junho de 2011 a 31 de junho de 2012. Para a caracteriza??o dos pacientes, foram coletados dados cl?nicos e pessoais e foi determinado escore Paediatric Index of Mortality 2 (PIM 2). Para a avalia??o da carga de trabalho de enfermagem foram utilizados os instrumentos TISS-28, NEMS e NAS, convertidos em horas de trabalho. Tamb?m, esses escores foram estratificados em dois grupos, no Grupo 1 foram reunidos os itens que comp?em a categoria atividades b?sicas; e o Grupo 2 reuniu os itens que comp?em as demais categorias de suporte ventilat?rio, cardiovascular, renal, neurol?gico e metab?lico e as interven??es espec?ficas. A presen?a do acompanhante foi avaliada por turno de trabalho e depois computada nas 24 horas de assist?ncia. A an?lise de dados foi baseada em estat?stica descritiva, teste t de Student ou ANOVA, correla??o de Pearson, regress?o linear simples e o modelo de Bland e Altman. A mortalidade foi analisada por meio do Standardized Mortality Ratio (SMR) e foi utilizada a Area Under Curve Receiver Operating Characteristic (AUROC). O dimensionamento do pessoal de enfermagem foi realizado com base em resolu??o do Conselho Federal de Enfermagem (Cofen). Resultados: A amostra foi composta por 490 interna??es, que totalizaram 4617 observa??es. Quanto ? caracteriza??o das crian?as, 53% eram do sexo masculino e houve predom?nio de lactentes e pr?-escolares, 39% eram menores de 1 ano de idade e 28% estavam na faixa et?ria entre 1 e 5 anos de idade. Em rela??o ? proced?ncia, 44% eram provenientes do centro cir?rgico, 21% da emerg?ncia, 20% da enfermaria e 16% de transfer?ncia de outro hospital. Muitas crian?as apresentaram mais de uma disfun??o org?nica durante a interna??o, destacando-se o fato de que 61% apresentaram disfun??o respirat?ria. Ao avaliar as m?dias de horas de trabalho da equipe de enfermagem estimadas pelos escores, observou-se que o instrumento NAS mensurou 13,6 horas e foi estatisticamente superior, em compara??o ao TISS-28 e ao NEMS, 11,7 e 12,9 horas, respectivamente. Na an?lise da m?dia de horas de trabalho estratificadas nos grupos, encontrou-se que no Grupo 1 o NAS mensurou 10,2?2,5 horas, destacando-se nessa avalia??o; por?m, quando considerado o Grupo 2, o TISS-28 estimou 6,3?3,1 horas, sobressaindo-se dentre os instrumentos. Melhores correla??es foram encontradas entre NAS e TISS-28, NAS(2) e TISS-28(2), NAS(2) e NEMS(2), NEMS e TISS-28 e NEMS(2) e TISS-28(2). Ao analisar a concord?ncia por meio do m?todo de Bland e Altman, observou-se que o TISS-28 e o NEMS foram os instrumentos que graficamente apresentaram a melhor concord?ncia. Segundo o valor m?dio do NAS, a carga de trabalho de enfermagem foi maior com as crian?as provenientes da emerg?ncia (14,15?3,89 horas), sem a presen?a do acompanhante (14,13?2,42 horas) e houve uma tend?ncia de aumentar a carga de trabalho com o aumento da quantidade de disfun??es org?nicas. O NAS tamb?m se mostrou eficaz na avalia??o da gravidade do caso, revelando no dia da admiss?o uma capacidade adequada de discrimina??o de mortalidade [AUROC de 0,811 (IC95% 0,726-0,896)], e em compara??o ao PIM 2 [AUROC de 0,813 (IC95% 0,716 - 0,910)]. O dimensionamento de pessoal utilizando a carga de trabalho estimada pelo NAS constatou a necessidade de 36 profissionais de enfermagem para atuar nessa unidade hospitalar. Conclus?o: O NAS mostrou-se o instrumento que melhor mensurou a carga de trabalho de enfermagem e, com as horas estimadas por meio deste escore, foi poss?vel dimensionar os recursos humanos de enfermagem na UTIP. Quanto ? caracteriza??o das crian?as internadas na UTIP durante o per?odo do estudo, houve predom?nio do sexo masculino, de lactentes menores de 1 ano de idade e de crian?as provenientes do centro cir?rgico. Este estudo agrupou os itens que comp?em os instrumentos NAS, TISS-28 e NEMS, separando a categoria atividades b?sicas das demais categorias de interven??es terap?uticas. O NAS se destacou no Grupo 1 na categoria atividades b?sicas e o TISS-28, no Grupo 2, que agrupou as demais categorias. Os instrumentos TISS-28 e NEMS foram os que apresentaram melhor correla??o e concord?ncia. Por meio das an?lises das cargas de trabalho m?dias totais, o NAS sobressaiu-se na estima??o da demanda de trabalho da enfermagem nessa unidade hospitalar. Houve aumento da carga de trabalho da enfermagem quando a crian?a estava sem a presen?a do acompanhante. O NAS apresentou capacidade de discrimina??o de mortalidade e de avalia??o da gravidade do caso.

Full textSnoring is generated by pharyngeal obstruction and vibration during sleep. Snoring is extremely common and may cause severe social problems and may indicate obstructive sleep apnea (OSA). However, there are no standardized methods for measuring snoring and the treatment of primary snoring or snoring associated with mild forms of OSA is controversial. Orofacial Myofunctional Therapy consists of isometric and isotonic exercises directed to tongue and soft palate for the treatment of moderated OSA. However, the effects of Orofacial Myofunctional Therapy on snoring were not objectively measured. OBJECTIVES: Primary: to determine the efficiency of Orofacial Myofunctional Therapy in reducing snoring of patients with primary snoring, mild and moderated OSA. Secondary: to develop a methodology to objectively quantify snoring; to assess the relation of snoring characteristics with OSA severity; to assess the effect of Orofacial Myofunctional Therapy upon the perception of snoring and sleep quality of the bed partner. METHODS: We included patients of both genders aged between 20 to 65 years old with polissomnographyc diagnoses of primary snoring, mild or moderated OSA. Patients were randomized for treatment with Orofacial Myofunctional Therapy or Control (use of nasal dilator strips and respiratory exercises) for 3 months. All patients were evaluated at the beginning and end of the study by questionnaires (Epworth, Pittsburgh), orofacial motricity assessment and complete polysomnography with the register of snoring. Bed partners assessed snoring and their own sleep quality (Pittsburgh). RESULTS: Thirty nine patients aged (mean ± standard deviation) =46 ± 13 yeas old and body mass index (BMI) (mean ± standard deviation) = 28,2 ± 3,1 Kg/m2, apnea hypopnea index (AHI)= 15,3 ± 9,3 events/hour, being 6 patients with primary snoring, 17 with mild OSA and 16 with moderated OSA completed the study. No significant change occurred in the Control Group in all variables. In contrast, patients treated with Orofacial Myofunctional Therapy presented (as compared to baseline) a significant decrease (p < 0.05) in neck circumference (38,0 [36,4-39,5] vs. 37,5 [36,0-39,0] cm), Orofacial Motricity Assessment (37,0 [23,0-42,0] vs. 19 [13,0-24,0]), Snoring Index (99,5 [49,6-221,3] vs. 48,2 [25,5-219,2]) and Total Snoring (60,4 [21,8-220,6] vs. 31,0 [10,1-146,5]). Bed partners of patients treated with Orofacial Myofunctional Therapy (n=13) reported a significant improvement in the perceived intensity (4,0 [2,5-4,0]) vs. 1,0 [1,0-2,0]) and snoring frequency (4,0 [3,0-4,0] vs. 2,0 [1,5-3,0]). Sleep quality of bed partners also improved but did not reach statistical significance (p=0.0618). Snoring Index and Total Snoring at basal and after 3 months presented a moderated correlation to OSA severity, measured by AHI (r between 0,505 to 0,603). CONCLUSIONS: Orofacial Myofunctional Therapy for 3 months is effective in reducing objectively measured snoring frequency and intensity. Orofacial Myofunctional Therapy can be effective for a great number of the population who present primary snoring or mild OSA forms

Electrical grounding is part of the Atmospheric Discharge Protection System (ADPS), whose functions are to provide a path for the circulation of electric current in the ground and to enable the detection of a possible fault between the energized conductors and the earth. For grounding to be efficient, some characteristics must be taken into account, such as soil type and resistivity. In this sense, measurements of resistivity and soil stratification are important for a correct sizing of the grounding system. Soils with high water concentration (low resistivity) are better current conductors than dry soils, for example. Soils with high resistivity can cause a return current. Thus, some decisions aimed at strengthening the grounding system should be taken when there are soils with inadequate grounding characteristics. Therefore, this work aims to evaluate the influence of soil electrical resistivity and enveloping types using concrete types in the substation electrical grounding system through software simulations, taking into account soil resistivity characteristics. In the analysis of types of envelopment, it was possible to observe that the concretes with greater amount of water in their composition have a lower electrical resistivity. The use of concrete enveloping is feasible for soils with high resistivity, as in the case of the land located in the city of Campinas, and it was possible to verify that for soils with low resistivity its use may be impractical since other options such as inclusion of more cables and installation of the rods in the layers with less resistivity are sufficient and more economical.
O aterramento el?trico faz parte do Sistema de Prote??o Contra Descargas Atmosf?ricas (SPDA), cujas fun??es s?o fornecer um caminho para a circula??o de corrente el?trica na terra, escoamento para a terra de cargas induzidas nas carca?as dos equipamentos el?tricos e, em conjunto com os dispositivos diferenciais-residuais, possibilitar a detec??o de uma poss?vel falha entre os condutores energizados e a terra. Para que o aterramento seja eficiente, algumas caracter?sticas devem ser levadas em considera??o, tais como o tipo e a resistividade do solo. Neste sentido, medi??es da resistividade e a estratifica??o do solo s?o importantes para um dimensionamento correto do sistema de aterramento. Solos com alta concentra??o de ?gua (baixa resistividade) s?o melhores condutores de corrente do que um solo seco, por exemplo. Solos com alta resistividade podem ocasionar uma corrente de retorno. Assim, algumas decis?es visando o refor?o do sistema de aterramento devem ser tomadas quando se tem solos com caracter?sticas inadequadas ao aterramento. Portanto, esse trabalho teve como objetivo avaliar a influ?ncia da resistividade el?trica do solo e de tipos de envelopamento utilizando tipos de concreto no sistema de aterramento el?trico de subesta??es atrav?s de simula??es em software, levando em conta as caracter?sticas de resistividade do solo. Nas an?lises de tipos de envelopamento, foi poss?vel observar que os concretos com maior quantidade de ?gua em sua composi??o possuem uma resistividade el?trica mais baixa. A utiliza??o do envelopamento de concreto ? vi?vel para solos com alta resistividade, como ? o caso do terreno localizado na cidade de Campinas, e foi poss?vel verificar que para solos com resistividade baixa sua utiliza??o pode ser invi?vel j? que outras op??es como inclus?o de mais cabos e instala??o das hastes nas camadas com menor resistividade s?o suficientes e mais econ?micas.

Cytogenetic studies have been revealing a great diversity not detected, until then, in several families of fishes. Many of these groups, especially those that exhibit great diversity, like Perciformes and Siluriformes, possess species with difficult morphologic characterization, called cryptic species, commonly detected through karyotypic analyses, which reveals outstanding interespecific variations with relationship to the number and its chromosomal structures. Thus, the present work intends to contribute for the cytogenetic knowledge of marine and brackish fish species, because they peculiar life habits and by lack of cytogenetic data of your genetic aspects. Therefore, cytogenetic studies were developed in a species of Apogonidae (Perciformes), two species of sea catfishes of the family Ariidae (Siluriformes) and brackish fish Paurachenipterus galeatus (Siluriformes, Auchenipteridae), through C banding, Ag-NOR, use of base-specific flourochromes (DAPI and CMA3), as well as FISH (Fluorescent in situ hybridization) using ribosomal DNA probes 5S and 18S. The present results contribute to a better understanding of the processes of differentiation patterns and chromosome evolution in these groups. The use of other approaches (the morphology and molecular tools) will allow a larger understanding of the genetic and biological diversity of the Brazilian ichthyofauna.

Muitos destes grupos, sobretudo os que exibem grande diversidade, como Perciformes e Siluriformes, possuem esp?cies de dif?cil caracteriza??o morfol?gica, chamadas de esp?cies cr?pticas, muitas vezes s? detectadas atrav?s de an?lises cariot?picas, as quais revelam varia??es interespec?ficas marcantes quanto ao n?mero e estrutura cromoss?mica. Desta forma, o presente trabalho pretende contribuir para o conhecimento citogen?tico de esp?cies marinhos e estuarinos, que, por n?o serem exploradas comercialmente ou terem h?bitos de vida peculiares s?o pouco estudadas quanto aos seus aspectos gen?ticos. Assim, an?lises cariot?picas foram desenvolvidas em uma esp?cie da fam?lia Apogonidae (Perciformes), em duas esp?cies de bagres marinhos da fam?lia Ariidae (Siluriformes), al?m de uma esp?cie de siluriforme estuarino, Paurachenipterus galeatus (Auchenipteridae) atrav?s de bandamento C, Ag-RONs, colora??o com DAPI e CMA3, bem como pela FISH (Fluorescent in situ hibridization), utilizando sondas ribossomais 5S e 18S. Os resultados aqui apresentados indicam grande diversidade inerente a estes grupos. Outras abordagens (an?lises morfol?gicas e ferramentas moleculares) permitir?o obter maior entendimento acerca da diversidade biol?gica da ictiofauna brasileira

Full textINTRODUCTION: Obstructive sleep apnea (OSA) is a public health problem, with high prevalence and severe consequences. The gold standard treatment for severe OSA is the application of continuous positive airway pressure (CPAP) during sleep. However, adherence to CPAP is low, especially in patients with primary snore and mild OSA. A previous study from our laboratory demonstrated that oropharyngeal exercises are effective in patients with moderate OSA (Guimaraes et. al, AJRCCM 2009:(179);962-966). Nonetheless, in this first study the number of patients included in the randomized trial was relatively small (n=31) and evaluated only patients with moderate OSA. Moreover, the number of oropharyngeal exercises the patients had to do 3 times a day was large (n=10) and raised doubt about the compliance to treatment, and the mechanism by which the therapy was effective was not elucidated. OBJECTIVE: The primary objective was to evaluate the effectiveness to reduce OSA severity of a short program of oropharyngeal exercises (6 exercises) in patients with primary snore, mild, moderate and severe OSA. The secondary objective was to evaluate the impact of reduced oropharyngeal exercises program on apnea hypopnea index (AHI) in patients stratified by baseline AHI, the anatomy of upper airway by magnetic resonance (MR), strength and fatigue of the tongue and critical closing pressure (Pcrit). METHODOLOGY: Patients of both sexes, with age between 20 and 65 years old, recently diagnosed with primary snore, mild, moderate or severe OSA who refused to use CPAP were included. Patients with body mass index (BMI) >= 35kg/m2, craniofacial deformities, edentulous, regular use of hypnotic medication, severe nasal obstruction, patients undergoing other treatments for OSA and patients with unavailability to comply with the protocol were excluded. The patients were evaluated at the beginning and end of the study by questionnaire of daytime sleepiness (Epworth, ranging from 0 to 24 points), quality of sleep (Pittsburgh, ranging from 0 to 21 points), oral myofunctional evaluation for OSA (ranging from 0 to 20 points), MR of the upper airway, tongue strength and fatigue, critical closing pressure (Pcrit) and polysomnography. The patients were randomized to 3 months of oropharyngeal exercises (6 exercises) or Control (use of nasal dilator strip and respiratory non specific respiratory exercises). All patients were instructed to perform the exercises 3 times a day and evaluated by a speech pathologist once a week. The primary endpoints were evaluated primarily by two-way repeated-measures ANOVA. A paired t test was also used as a secondary evaluation. RESULTS: A total of 251 patients were evaluated and 60 patients were randomized. The 2 groups (n=30) were similar at study entry for all the parameters and 58 patients completed the study (58.6% males, age: 45.9±12.2 years, BMI: 28.8±4.3 kg/m2, AHI=18.4±12.6 events/h and minimum saturation84.9±6.4%). All variables remained unchanged in the Control group. There were no changes in Epworth and Pittsburgh questionnaires as well as BMI in patients randomized to oropharyngeal exercises. As compared to study entry, there was a significantly reduction on neck circumference (38.8 ± 3.3 vs 38.4±4.4cm), arousals index (21.3 ± 10.9 vs 16.9 ± 7.9 arousals/h), AHI (19.5 ± 14.2 vs 15 ± 10.2 events/h), oral myofunctional evaluation for OSA (9.3 ± 2.9 vs 3.6 ± 2.4) in the patients randomized for oropharyngeal exercises. Oropharyngeal exercises only reduced AHI significantly among patients with moderate OSA (23.8 ± 5.2 vs 17.7 ± 5.2) and severe OSA (43.9 ± 19.5 vs 24.7 ± 21.4) at study entry. No significantly changes as evaluated by two-way repeated-measures ANOVA were observed on upper airway MR anatomy (10 Control and 14 oropharyngeal exercises), tongue force and fatigue (19 Control and 19 oropharyngeal exercises) and Pcrit (7 Control and 10 oropharyngeal exercises). As compared to study entry there was a significant reduction as evaluated by paired T test on tongue volume (p=0.031), tongue fat (p=0.008) and a significant increase of tongue strength (p=0.046) of patients randomized to oropharyngeal exercises. CONCLUSION: A short program of oropharyngeal exercises is effective to reduce OSA severity in patients with moderate and severe OSA. The trend to increase tongue strength and reduce tongue fat may explain the beneficial effects of oropharyngeal exercises
