Adaptação e validação da escala GenCat de calidade de vida para a população adulta portuguesa com deficiência

Para melhorar o apoio social prestado às pessoas com deficiência em Portugal, urge perceber como esta população perceciona a própria Qualidade de Vida (QV). Este trabalho tem como objetivos: adaptar e validar a escala Gencat de Calidade de vida à população portuguesa adulta com deficiência; estudar como se manifesta a Qualidade de Vida na população portuguesa adulta com deficiência; analisar a relação de QV com algumas variáveis socio demográficas da população portuguesa adulta com deficiência, tipos de incapacidades e gravidade da amostra. A escala Gencat foi aplicada a 303 pessoas com perturbações motoras, sensitivas e/ou do desenvolvimento. Foi realizada a caraterização sociodemográfica do informador e da pessoa avaliada e a caracterização da gravidade da perturbação sofrida. O estudo psicométrico resultou numa escala de 54 itens e 8 domínios: Autodeterminação, Suporte Institucional, Satisfação Ocupacional, Bem-Estar Emocional, Inclusão Social, Condições Habitacionais e Comunitárias, Auto-eficácia e Bem-estar Físico. A escala apresenta boas propriedades psicométricas. A idade está inversamente correlacionada com as dimensões apoio institucional e bemestar físico da escala de Gencat. A população analfabeta apresenta menor QV global, nomeadamente na autodeterminação, suporte institucional, inclusão social e bem-estar físico. As pessoas institucionalizadas relativamente às que vivem em contexto familiar apresentam valores mais baixos de QV, nomeadamente na autodeterminação, suporte institucional, inclusão social e auto-eficácia, mas apresentam pontuações melhores condições habitacionais e comunitárias. O grau de incapacidade e a intensidade das perturbações cognitiva, motora, autismo e cegueira correlaciona-se inversamente com a QV, nomeadamente na autodeterminação, no suporte institucional, na inclusão social e o bem-estar físico.

Como a Fada Desvalorizada Lida com o Lar

Para compreender a auto-avaliação e avaliação social atribuída ao trabalho da mulher Doméstica, partiu-se da análise e interpretação de 8 Trajetórias Identitárias de Mulheres Domésticas Alentejanas que ao longo da sua vida tenham sido Domésticas a tempo inteiro, ou que de algum modo tenham conciliado ou conciliem a Dupla Tarefa. A Problematização do Trabalho realizado pela Mulher Doméstica considerou teorias de autores como Parsons e Daniel Bertaux, tendo sido a conceptualização do Trabalho Doméstico elaborada tendo por base Virgínia Ferreira;, Gules Lipovetsky e Ana Nunes de Almeida. A partir das narrativas exemplares e seguindo uma metodologia compreensiva qualitativa, através do Método de Escrita como Praxis Analítica, identificaram-se: algumas Lógicas de Acção; vários Territórios Sócio-Identitários; as Reacções sentidas pelas 8 narradoras nas suas Trajetórias e, ainda, as Estratégias adoptadas pelas Mulheres Domésticas Alentejanas na relação com o trabalho doméstico e com a dupla tarefa. Ao concluir a interpretação dos casos percebe-se que, para além da Condição de Doméstica comum entre todas as narradoras, existe ainda a predominância de alteração dos Territórios Sócio-Identitários Laboral, Escolar e Familiar. É clara a consciência destas mulheres quanto à desvalorização do Trabalho Doméstico pela Família e pela Sociedade. Neste sentido, é também negativa a auto-avaliação, das tarefas de diariamente realizam. Daí que seja unânime a vontade de libertação através da Dupla Tarefa, ou seja, a colocação profissional é vista como uma garantia de reconhecimento do seu trabalho e, também, um modo de autonomia económica e identitária.

Ki-67 Proliferation Index in Gastric Cancer - Biologic Significance

Objectives/Introdution: Ki-67 protein has been used as an indicator of proliferation activity in tumor cells. In gastric cancer the prognostic value has not been fully understood. This study was designed to assess the biologic significance of Ki-67 proliferation index (PI) in gastric cancer. Material/Methods: Seventy-two patients with gastric cancer were evaluated. These patients underwent gastric resection, and the tumor tissue was stained immunohistochemically. Ki-67 PI was defined as the percentage of tumor cells positive for Ki-67. Ki-67 PI was correlated with clinicopathological characteristics and patient survival. Results: A low Ki-67 PI (less than or equal to 50%) was associated with poorly differentiated histology - diffuse type (p=0.009) and signet ring cells (p=0.004) - and younger age (p=0.022). A worse prognosis in patients with low Ki-67 PI was also found (a mean survival of 41.8 vs 63 months for high Ki-67 PI group), but not statistically significant (p=0.623, log rank test). Discussion/Conclusion: We found an inversely correlation between Ki-67 PI and histological differentiation grade. Patients in group with low Ki-67 PI are younger, with poorly differentiated histology and have a lower mean survival. Like other studies already suggested, we may have two different tumors phenotypes - highly invasive with low proliferative capability, and less invasive potential with higher proliferative ability. However, in this sample, no significant prognostic value was achieved between both.

An overview on how failure analysis contributes to flight safety in the Portuguese Air Force

Failure analysis has been, throughout the years, a fundamental tool used in the aerospace sector, supporting assessments performed by sustainment and design engineers mainly related to failure modes and material suitability. The predicted service life of aircrafts often exceeds 40 years, and the design assured life rarely accounts for all in service loads and in service environmental menaces that aging aircrafts must deal with throughout their service lives. From the most conservative safe-life conceptual design approaches to the most recent on-condition based design approaches, assessing the condition and predicting the failure modes of components and materials are essential for the development of adequate preventive and corrective maintenance actions as well as for the accomplishment and optimization of scheduled maintenance programs of aircrafts. Moreover, as the operational conditions of aircrafts may vary significantly from operator to operator (especially in military aircraft), it is necessary to access if the defined maintenance programs are adequate to guarantee the continuous reliability and safe usage of the aircrafts, preventing catastrophic failures which bear significant maintenance and repair costs, and that may lead to the loss of human lives. Thus being, failure analysis and material investigations performed as part of aircraft accidents and incidents investigations arise as powerful tools of the utmost importance for safety assurance and cost reduction within the aeronautical and aerospace sectors. The Portuguese Air Force (PRTAF) has operated different aircrafts throughout its long existence, and in some cases, has operated a particular type of aircraft for more than 30 years, gathering a great amount of expertise in: assessing failure modes of the aircrafts materials; conducting aircrafts accidents and incidents investigations (sometimes with the participation of the aircraft manufacturers and/or other operators); and in the development of design and repair solutions for in-service related problems. This paper addresses several studies to support the thesis that failure analysis plays a key role in flight safety improvement within the PRTAF. It presents a short summary of developed

Proposta de método para avaliação do desempenho térmico de residências unifamiliares em clima quente e úmido

Nowadays, evaluation methods to measure thermal performance of buildings have been developed in order to improve thermal comfort in buildings and reduce the use of energy with active cooling and heating systems. However, in developed countries, the criteria used in rating systems to asses the thermal and energy performance of buildings have demonstrated some limitations when applied to naturally ventilated building in tropical climates. The present research has as its main objective to propose a method to evaluate the thermal performance of low-rise residential buildings in warm humid climates, through computational simulation. The method was developed in order to conceive a suitable rating system for the athermal performance assessment of such buildings using as criteria the indoor air temperature and a thermal comfort adaptive model. The research made use of the software VisualDOE 4.1 in two simulations runs of a base case modeled for two basic types of occupancies: living room and bedroom. In the first simulation run, sensitive analyses were made to identify the variables with the higher impact over the cases´ thermal performance. Besides that, the results also allowed the formulation of design recommendations to warm humid climates toward an improvement on the thermal performance of residential building in similar situations. The results of the second simulation run was used to identify the named Thermal Performance Spectrum (TPS) of both occupancies types, which reflect the variations on the thermal performance considering the local climate, building typology, chosen construction material and studied occupancies. This analysis generates an index named IDTR Thermal Performance Resultant Index, which was configured as a thermal performance rating system. It correlates the thermal performance with the number of hours that the indoor air temperature was on each of the six thermal comfort bands pre-defined that received weights to measure the discomfort intensity. The use of this rating system showed to be appropriated when used in one of the simulated cases, presenting advantages in relation to other evaluation methods and becoming a tool for the understanding of building thermal behavior

Ventilação e prescrições urbanísticas: uma aplicação simulada para a Orla da Praia do Meio em Natal/RN

This work analyses a study on natural ventilation and its relation to the urban legislation versus the building types in an urban fraction of coastal area of Praia do Meio in the city of Natal/RN, approaching the type or types of land use most appropriate to this limited urban fraction. The objective of this study is to analyse the effects of the present legislation as well as the types of buildings in this area on the natural ventilation. This urban fraction was selected because it is one of the sites from where the wind flows into the city of Natal. This research is based on the hypothesis stating that the reduction on the porosity of the urban soil (decrease in the set back/boundary clearance), and an increase in the form (height of the buildings) rise the level of the ventilation gradient, consequently causing a reduction on the wind speed at the lowest part of the buildings. Three-dimensional computational models were used to produce the modes of occupation allowed in the urban fraction within the area under study. A Computational Fluid Dynamics (CFD) software was also used to analyse the modes of land occupation. Following simulation, a statistical assessment was carried out for validation of the hypothesis. It was concluded that the reduction in the soil porosity as a consequence of the rates that defined the minimum boundary clearance between the building and the boundary of the plot (and consequently the set back), as well as the increase in the building form (height of the buildings) caused a reduction in the wind speed, thus creating heat islands

Performance-arte : fracasso, tempo e repetição

Vivemos um tempo de incerteza e instabilidade. Vivemos um tempo em que o presente se reproduz e se reinventa continuamente sem a perspectiva de um futuro certo e perdurável. A presente dissertação orienta-se em torno de um corpo de trabalho de experimentação artística que explora a relação entre arte contemporânea e fracasso. Trata-se, aqui, de reflectir sobre a natureza paradoxal do fracasso, sobre a utilidade e inutilidade do fracasso na sociedade e na artecontemporânea ocidental. Entre a intenção e a realização, entre a perspectiva de sucesso e o fracasso alcançado, abre-se um espaço gerador (potência)ocupado pela dúvida e questionamento, suporte essencial do pensamento e da acção humana. Corpo fracasso (descendente de Sísifo) dedicado a tarefas inúteis (nãoprodutivas) e repetitivas no tempo como alternativa ao corpo sucesso (base-docapitalismo), dedicado a tarefas úteis (produtivas) e repetitivas no tempo.

A influência de decisões arquitetônicas na eficiência energética do Campus vol. 1/UFRN

Building design is an effective way to achieve HVAC energy consumption reduction. However, this potentiality is often neglected by architects due to the lack of references to support design decisions. This works intends to propose architectural design guidelines for energy efficiency and thermal performance of Campus/UFRN buildings. These guidelines are based on computer simulations results using the software DesignBuilder. The definition of simulation models has begun with envelope variables, partially done after a field study of thirteen buildings at UFRN/Campus. This field study indicated some basic envelope patterns that were applied in simulation models. Occupation variables were identified with temperature and energy consumption monitoring procedures and a verification of illumination and equipment power, both developed at the Campus/UFRN administration building. Three simulation models were proposed according to different design phases and decisions. The first model represents early design decisions, simulating the combination of different types of geometry with three levels of envelope thermal performance. The second model, still as a part of early design phase, analyses thermal changes between circulation halls lateral and central and office rooms, as well as the heat fluxes and monthly temperatures in each circulation hall. The third model analyses the influence of middle-design and detail design decisions on energy consumption and thermal performance. In this model, different solutions of roofs, shading devices, walls and external colors were simulated. The results of all simulation models suggest a high influence of thermal loads due to the incidence of solar radiation on windows and surfaces, which highlights the importance of window shading devices, office room orientation and absorptance of roof and walls surfaces
