A simulao, como ferramenta de suporte tomada de deciso, tem sido utilizada nas mais variadas reas do conhecimento e especialmente no projeto e dimensionamento de plantas de produo. Em geral, os simuladores para sistemas de produo consideram variveis relativas quantidade, tipo e disposio fsica de mquinas, quantidades dos estoques intermedirios, e aos tempos de produo sem, no entanto, considerar os tempos reais do trabalho do ser humano envolvido no processo, apesar de a mo de obra humana ser largamente empregada nestes sistemas, afetando diretamente a sua produtividade. Uma das possveis razes disto a complexidade dos fatores que influenciam na produtividade do ser humano, que varia em funo de fatores ambientais, fisiolgicos, psicológicos ou sociais. Normalmente, os sistemas de simulao da produo representam o trabalhador humano da mesma forma como representam uma mquina, uma ferramenta ou um equipamento, cuja previsibilidade bem maior. Esta dissertao avalia a questo humana em um simulador bastante utilizado comercialmente, e evidenciou que os fatores ergonmicos so capazes de alterar significativamente os resultados de uma simulao, justificando o desenvolvimento de rotinas computacionais capazes de representar o elemento humano e suas interaes com o sistema, de forma mais fidedigna.

Venous ulcer (VU) is a lower limbs injury resulting from inadequate return of venous blood in feet or legs. Although it is not a deadly disease, it causes chronic wounds, which seriously undermine patients quality of life (QOL) and sometimes leads to drastic family, social, economic and psychological changes. In this sense, there are several aspects that may influence the venous ulcers patients QOL. The studys objective aimed on the association of socio-demographic and health, health care and clinical injury on UV patients‟ QOL. Analytical studies, which consider the complexity of factors involved in changes in UV patients‟ QOL has a cross-sectional and quantitative approach. The HUOL Ethics Committee approved this project (n.279/09). The collection of data lasted a period of 3 months in 2010 and it took place at the clinic of Angiology at Hospital Universitrio Onofre Lopes (HUOL). The data sample consisted of 60 patients treated by UV angiologists in the HUOL Surgical Clinic. The results were analyzed with SPSS 15.0 by descriptive and inferential statistics. The study was based on UV patients that were predominantly female, average age of 61.4 years, that had low education level and low family income, with occupations requiring long periods of standing or sitting, but mostly retired, unemployed or laid off due to the disease and/or due to chronic diseases associated with the UV. The study took also into consideration patients that used inappropriate products, that were improperly treated by a professional caregiver, that lacked of adequate guidance and compression therapy, that performed no lifting of the lower limbs and regular exercise, that the time of injury were greater than or equal to six months, that were missing specific laboratory tests. The study‟s reference were on recurrent lesions, medium to large lesions area, bed of the lesion (injuries) with fibrin and/or necrosis, with amount of exudate with medium to large, odorless and no signs of infection, with tissue loss between 1st and 2nd degree, without collecting swab or biopsy and with pain. In general, QOL of researched individuals were considered low, the maximum score was 69 points, which the areas that were mostly influenced were the total scores of QOL functional capacity (0.021), emotional (0.000) and social functioning (0.080). Of the 60 individuals, 53.3% had scores between 40 and 69 points in SF-36, and they had the best scores in sociodemographic and health variables (ρ = 0.049). In respect to the assistance and injury characteristics, patients who scored between 40 and 69 points in SF-36 had better scores on these characteristics. By combining the socio-demographic variables, health, and handling characteristics of the injury, we observed a significant difference (ρ = 0.032) when linking them with the QOL total scores. When analyzing separately the domains of the SF-36 scores on the quality of life, we find that the areas that showed statistical significance were functional ability (ρ = 0.035), appearance (ρ = 0.019), emotional (ρ = 0.000), and mental health (ρ = 0.050). Among the socio-demographic characteristics studied, gender and marital status contributed more to the reduction of QOL and among the variables of assistance and the injury, orientation, reference and area of UV contributed the most. By analyzing these five variables all together in accordance with the overall score obtained in the quality of life, we found a significant correlation (ρ = 0.002); with 6.23 times more chances of patients have better QOL in the presence of these five positive factors. By conducting the Mann Whitney U test between all the five demographic variables, health, and clinical care, we found that this combination also proved to be significant (ρ = 0.006). Therefore, patients with these five variables positive tend to have a better QOL. Based on these results, we reject the null hypothesis (H0) and accept the alternative hypothesis (H1) proposed in this study because we noted that the QOL of patients with UV is associated with sociodemographic and health, health care and clinical aspects of the injury

The Lusiads is an epic poem, written by Lus de Cames, about the adventure of Vasco da Gama s trip and the history of Portugal. It's based on traditionals epics from the Greek and Roman poets, Homero and Virglio. Cames followes especially their structures. However, the poet insert modifications that divert his poem from parameters established by Aristteles for the classic epic poems. These deviations are centered mainly on the narrative subject and in the point of view. We intend to show an analysis focused on digressions from The Lusiads, in which the author, himself or by tellers characters, narrates the story in order to make his complaints, reflections and exhortations. Besides, we present general aspects of Maneirismo predominant in these digressions how evidences of modernity of the poem; as one brief outlook about the poem's projection in time and around the world. These points are importants elements of consolidation of a universal permanence of The Lusiads. That's why they have had to read and to study by the centuries, according the vision of the epoch's spirit

Introduo: A asma se tornou um problema de sade pblica devido aos seus grandes custos em cuidados de sade. Os exercícios respiratrios constituem uma interveno no farmacolgica de baixo custo e baixo risco que vem sendo utilizada por fisioterapeutas em diferentes pases no tratamento de pacientes asmticos. Objetivo: Avaliar a eficcia dos exercícios respiratrios no tratamento de pacientes adultos com asma nos seguintes desfechos: qualidade de vida, sintomas da asma, nmero de exacerbaes agudas, episdios de hospitalizao, mensuraes fisiolgicas (funo pulmonar e capacidade funcional), nmero de consultas mdicas, nmero de faltas no trabalho devido a exacerbaes da doena, avaliao subjetiva do paciente em relao interveno. Mtodo: Reviso sistemtica de estudos controlados randomizados com metanlise realizada em parceria com a Colaborao Cochrane. As seguintes bases de dados foram consultadas: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, AMED, e PsycINFO, alm de busca manual em revistas da rea e em resumos de congressos. Os seguintes termos foram utilizados: (breath*) and (exercise* or retrain* or train* or re-educat* or educat* or physiotherap* or "physical therap*" or "respiratory therapy" or buteyko ). As listas de referncias dos estudos selecionados e registros de ensaios clnicos tambm foram consultados. A seleo dos estudos e a avaliao do risco de vis dos estudos includos foram realizadas de maneira independente por dois revisores. O software Review Manager foi utilizado para anlise dos dados, no qual o modelo de efeito fixo foi utilizado. As variveis contnuas foram expressas como diferena de mdia ponderada com um intervalo de confiana de 95%. A heterogeneidade dos resultados dos estudos includos foi realizada por meio da anlise dos Forest plots. O teste qui-quadrado (Chi2) com um P valor de 0.10 foi utilizado para indicar significncia estatstica. O ndice de heterogeneidade (I2) foi implementado com um valor acima de 50% como um nvel substancial de heterogeneidade. Resultados: 13 estudos envolvendo 906 pacientes esto atualmente includos na reviso. Os seguintes desfechos foram mensurados pelos estudos includos: qualidade de vida, sintomas da asma, nmero de exacerbaes agudas e funo pulmonar. Os estudos relataram uma melhora na qualidade de vida, sintomas da asma e nmero de exacerbaes agudas. Seis dos onze estudos que avaliaram funo pulmonar mostraram uma diferena significativa favorvel aos exercícios respiratrios. No houve relato de efeitos adversos. Devido heterogeneidade substancial encontrada entre os estudos, metanlise foi possvel apenas para sintomas da asma, a qual incluiu dois estudos e mostrou uma diferena significativa favorvel aos exercícios respiratrios. A avaliao do risco de vis foi prejudicada devido ao relato incompleto de aspectos metodolgicos pela maioria dos estudos includos. Concluso: Embora os resultados encontrados pelos estudos includos demonstraram individualmente que os exercícios respiratrios podem ser importantes no tratamento da asma, no h evidncia conclusiva nesta reviso para suportar ou refutar a eficcia desta interveno no tratamento de pacientes asmticos. Este fato foi devido s diferenas metodolgicas entre os estudos includos e ausncia de relato de aspectos metodolgicos por parte da maioria dos estudos includos. No h dados disponveis em relao aos efeitos dos exercícios respiratrios nos seguintes desfechos: episdios de hospitalizao, nmero de consultas mdicas, nmero de faltas no trabalho devido a exacerbaes da doena, e avaliao subjetiva do paciente em relao interveno

Techniques of mind & body control seem to benefit human organism in general and cognition in particular, because they involve a mindfulness practice. However, there is still a scarcity of studies with well-controlled methods to investigate the possible effects of Yoga practice. In this study, we investigated the effects of regular Yoga practice, based on Yoga postures (asanas), breathing techniques, and meditation exercises, on memory and physiologic and psychological parameters related to quality of life. There were significant improvements on performance tasks of short term memory and long term memory. We also observed significant beneficial effects on psychological and physiological parameters such as mood, anxiety, depression, stress, and modulation of the autonomic nervous system in Yoga practitioners group compared to the conventional physical exercises group. The results suggest the possible influences of stress, emotional state and mental training on cognitive effects of yoga practice. Our results support the indication of practice of Yoga for the treatment or prevention of stress, psychological disorders and their possible cognitive consequences
