O envelhecimento é um processo que, a nível individual, remete para múltiplas trajetórias de vida e que, no plano coletivo, sofre a influência de fatores socioculturais como acesso à educação, aos cuidados em saúde, à alimentação e ao lazer e a uma rede de relações estáveis. Na literatura gerontológica, envelhecer é considerada uma situação progressiva e multifatorial, e a velhice uma experiência heterogénea, experienciada com mais ou menos qualidade de vida e potencialmente bem-sucedida (Lima, Silva & Galhardoni, 2008). Analisar a velhice como uma experiência homogénea, não significa apenas minimizar os problemas enfrentados pelos idosos, decorre do fato de a sociedade moderna não ter previsto um papel específico ou uma atividade para os velhos, remetendo-os para uma existência sem significado (Areosa, Bevilacqua & Werner, 2003). Atualmente, tem sido o modelo de envelhecimento ativo que tem ocupado um lugar cimeiro nas agendas mundiais das diferentes organizações internacionais desde a Organização Mundial de Saúde (OMS), à Comissão Europeia e às entidades de saúde e segurança social dos diferentes estados membros. Neste âmbito têm vindo a ser propostas e acionadas estratégias políticas e desenvolvidas medidas de intervenção social que procuram traduzir uma nova imagem da velhice e promover novas leituras e práticas sobre esta realidade. O modelo subjacente ao envelhecimento ativo conceptualiza o envelhecimento sob uma perspectiva positiva, refutando estereótipos e valorizando o papel desempenhado pelos idosos tal como os contributos que prestam à sociedade. A saúde, o bem-estar e a autonomia não só são possíveis e desejáveis, como se opõem à incapacidade e dependência. O idoso deixa de ser um personagem vulnerável e passivo, para se assumir como um agente ativo e decisor no seu processo de envelhecimento, (Rozario, Morrow-Howell & Hinterlong, 2004). O envelhecimento ativo, centrado na ideologia da atividade e jovialidade desafia os idosos para a necessidade de uma reinvenção pessoal através da criatividade na reconstrução de um novo projeto de identidade e de ocupação na aposentação, que promova a sua participação social e que contrarie a ideia de dependência dos incentivos sociais e das iniciativas públicas (Silva, 2009). Nesta perspetiva, pretende-se que o envelhecimento ocorra com qualidade e manutenção da autonomia dos indivíduos, criando e preservando oportunidades de os mais velhos continuarem a participar da sociedade, minimizando assim as possibilidades de exclusão social (Lima et al., 2008). Neste contexto, pretende-se analisar como é que o envelhecimento ativo é representado pelos idosos e pelos profissionais de saúde. Assim, o objetivo deste estudo visou identificar a estrutura das representações sociais do envelhecimento e do envelhecimento ativo de um grupo de idosos e de um grupo de profissionais de saúde, do concelho de Évora.

Este estudo visa identificar as imagens do processo de envelhecimento e da velhice, as imagens relacionadas com a preparação de um envelhecimento bem sucedido e compreender a relação entre as mesmas. Pretende-se ainda identificar possíveis linhas de intervenção que permitam modificar imagens da velhice e da sua preparação, capazes de promover activamente um envelhecimento bem sucedido. Optou-se por um estudo de desenho de carácter transversal, descritivocorrelacional, com recurso à técnica de análise quantitativa para correlações entre diferentes variáveis sócio-demográficas. A amostra compreende 800 sujeitos com idades compreendidas entre os 13 e os 87 anos, analisadas as seguintes variáveis sociodemográficas: idade, género, escolaridade, estado civil, ter ou não filhos, se trabalhou ou não com pessoas idosas e freguesia de residência (urbana ou rural). Os instrumentos utilizados foram duas escalas, a ImAge e a ImPreVe. Os principais resultados indicam que: a) os sujeitos que manifestam imagens positivas tendem a preocupar-se com a preparação da velhice, a viver no presente mas também a planear o seu futuro; b) os sujeitos que manifestam imagens negativas da velhice e do envelhecimento também tendem a preocupar-se com a preparação da velhice, a focalizar-se no futuro; c) os sujeitos que manifestam imagens ambivalentes (positivas e negativas, onde há ganhos e perdas em simultâneo) tendem a considerar a preparação como pouco importante; d) são os sujeitos mais velhos e com menor escolaridade quem tende a manifestar imagens negativas e a valorizar a preparação da velhice. A promoção de um envelhecimento bem sucedido deve incidir nas dimensões individual, familiar, social e institucional, com vista à alteração de imagens irreais e baseadas em estereótipos ou preconceitos (sejam positivas ou negativas), ajustadas à realidade do normal processo de envelhecimento. Impõe-se uma mudança dessas imagens, desmistificando a sua conjugação com o envelhecimento patológico e promover activamente estratégias adequadas a cada perfil para a promoção de um envelhecimento bem sucedido.

A população portuguesa encontra-se num processo de envelhecimento, e tem de enfrentar esta nova realidade demográfica. Vários determinantes nomeadamente biológicos, psicológicos e sociais, foram já identificados. O aumento da prevalência de doenças crónicas e incapacitantes, como consequência directa do envelhecimento humano, tem aumentado a procura de respostas na área da saúde e ao nível social. A Rede Nacional de Cuidados Continuados Integrados (REDE) surge como resposta a esta nova problemática. Através da implementação de Unidades de Cuidados Continuados Integrados (UCCI), a REDE é uma alternativa aos internamentos nos hospitais de pessoas em situação de dependência e com necessidade de cuidados diferenciados mas sem necessidade de cuidados típicos de uma unidade de agudos. As UCCI apresentam um modelo de intervenção multidisciplinar que contempla as vertentes da saúde, social e económica dos utentes, composta por equipas multidisciplinares. Devido às especificidades da população idosa e/ou dependente, a intervenção especializada dos profissionais das UCCI, deve ser cuidadosamente preparada com base no treino e especialização, aspectos centrais do sucesso da REDE.

As pessoas idosas constituem hoje um novo grupo populacional! Também é novo o conhecimento de suas características e do processo do envelhecimento. A pesquisa acadêmica em torno dos diversos aspectos da população de mais idade tem tido um significativo desenvolvimento e a cada ano, mais e mais estudos têm sido feitos. Entretanto, estes são praticamente desconhecidos no Brasil. Ao mesmo tempo, as pessoas idosas estão se tornando cada vez mais importantes sob o ponto de vista da política social e a questão da previdência social e da aposentadoria têm sido debatidas em torno do problema de como a sociedade deveria prover esta etapa da vida. Nosso estudo é sobre a forma de atendimento das pessoas idosas comum no Brasil, isto é, a forma institucional de recolhimento: o asilo. Estudamos três deles, descrevendo suas características e dinâmica interna mostrando a condição de total dependência em que se encontram as pessoas idosas que vivem ali. A finalidade específica do estudo de campo foi a de oferecer uma perspectiva com relação a Psicologia do Envelhecimento e a discussão do papel preventivo e profilático que o psicólogo pode ter no campo do envelhecimento.

The gradual replacement of conventional materials by the ones called composite materials is becoming a concern about the response of these composites against adverse environmental conditions, such as ultraviolet radiation, high temperature and moist. Also the search for new composite using natural fibers or a blend of it with synthetic fibers as reinforcement has been studied. In this sense, this research begins with a thorough study of microstructural characterization of licuri fiber, as a proposal of alternative reinforcement to polymeric composites. Thus, a study about the development of two composite laminates was done. The first one, involving only the fiber of licuri and the second comprising a hybrid composite based of fiber glass E and the fiber of licuri, in order to know the performance of the fiber when of fiber across the hybridization process. The laminates were made in the form of plates using the tereftálica ortho-polyester resin as matrix. The composite laminate made only by licuri fiber had two reinforcing fabric layers of unidirectional licuri and the hybrid composite had two reinforcing layers of unidirectional licuri fabric and three layers of fiber short glass-E mat. Finally, both laminates was exposed to aging acceleration in order to study the influence of environmental degradation involving the mechanical properties and fracture characteristics thereof. Regarding the mechanical properties of composites, these were determined through uniaxial tensile tests, uniaxial compression and three bending points for both laminates in original state, and uniaxial tensile tests and three bending points after accelerated aging. As regards the study of structural degradation due to aging of the laminates, it was carried out based on microscopic analysis and microstructure, as well as measuring weight loss. The characteristics of the fracture was performed by macroscopic and microscopic (optical and SEM) analysis. In general, the laminated composites based on fiber licuri showed some advantages in their responses to environmental aging. These advantages are observed in the behavior related to stiffness as well as the microstructural degradation and photo-oxidation processes. However, the structural integrity of this laminate was more affected in case the action of uniaxial tensile loads, where it was noted a lower rate of withholding his last resistance property

This study aims to identify the social representations built on senior care health workers of Primary Care. This is an exploratory research within the subsidized social representations held in 100 Basic Health Units in the city of João Pessoa-PB, with a sample of n= 204 workers of both sexes, who agreed to participate. To collect the data used to set an interview in two parts: the first looked at the Test of Free Association of Words using the inductive stimulus "senior care". The interviews were analyzed with the help of a software for quantitative analysis of textual data ALCESTE (version 2010). The results were interpreted from the theoretical framework of social representations. The study included 178 women (87.25%) and 26 men (12.75%), working in Family Health Units in the city of João Pessoa, the majority are aged between 40-49 years of age ( 28.92%), and have higher education with 81.86%. The results of Alceste link to the term inducer six (6) where the hierarchical classes representing senior care workers as synonymous with care and attention, showing situations neglect of the elderly, for that patience is required to promote the increase of disease prevention and living with the elderly to generate humanization in health services. It is considered that the social representations of health workers on assistance to the elderly may support modeling of strategic actions in health services with health promotion programs for large groups, able to modify practices and behavior in elder care and strengthening the policy was directed at the elderly

It discusses the Health Care of the Elderly in the town of Mossoró, traversing the paths that discussed the history of health care, which has been altered by the new (con) formation and required adjustments of society which led the development and implementation of the National Health Care for the Elderly with the backdrop of the guiding principles of the Health System - SUS. The goals outlined were: To map the implementation of the policy of health care for the elderly in Mossoró considering whether this is based on the principles and guidelines of the NHS and National Health Policy of the Elderly; Check if health promotion is seen as a strategy that favors the elderly mossoroenses the possibility of healthy aging; identify the discourse of the elderly about the aging process and the strategies you use to take care of your needs. Applies as a methodological strategy BOAS, complemented by interviews with twenty (20) elderly residents of Mossoró with a view to understand the objective elements, and the political and subjective traits that express a regularity which marks the area of health care mossoroense elderly. The data were tabulated and the BOAS divided into nine sections for analysis. The speeches were transcribed seized and subjected to a thorough reading that allowed the visualization of issues that have been examined with theoretical and methodological support to the model proposed by Boaventura de Souza Santos (2006) designated this cosmopolitan reason being supported by three meta-sociological procedures, namely, the sociology of absences, the sociology of translation work and emergencies. It appears as a result the exclusion and discrimination of the elderly in different social settings, a condition that prevents them from being aware of their importance as citizens deserving of decent treatment and respect for the family, society and the government, when addressing health the elderly said the need to propose alternative models of care that has the paradigm of health promotion. We conclude that in these areas, meetings are held, to draw lines that were heterogeneous because they were built by the dissimilarities that engender incessantly and show that although we have advanced regarding the attention of the elderly in Mossoró there is still a long way to go in order to meet the needs revealed by the elderly. It is suggested that the practice of trial-creation-differentiation, while highlighting the historical and procedural dimension, deconstructions and negotiations with collective effects. A democratic paradigm and analytical creeps: the constitution are moments of Health Care for the Elderly shaping a new landscape in the town of Mossoró.

The aging process lived by the Brazilian population concurred to the transformation in the family models, causing difficulties related to the elderly care on the Family environment, a fact that is one of the main reasons for their institutionalization. Facing this scenario, the need of investigating how the elderly lives on the long-term facilities (ILPI) has aroused. In this study, it has been conducted an analysis of the populational aging process, contrasting the Rio Grande do Norte to Brazil and the Northeast Region, between 1980 to 2010. Faced with the realization of this process, and the rising number of long-term facilities for the elderly (ILPI), it was needed to make a rescue of the abiding laws regarding elderly institutionalization, on the scope of Natal, which surged after the 1988 Federal Constitution, checking what were the impacts on the assistance of the institutionalized elderly. Lastly, it were investigated the possible determinants associated with the institutionalization, in Natal-RN, considering the aspects of the family structure, family relationship, economic, health and well being of the elderly. The results showed that Rio Grande do Norte, particularly Natal, follows the national scene, since between 1980 and 2000 its population passed the intermediate level in the process of population aging for, in 2010, to be considered elderly. Throughout this process, it was observed that Natal has been adapting to the federal legislation, through the creation of the municipal policy, City Council and other relevant standards for the elderly, promoting significant changes in ILPI.However, philanthropic institutions needs better resources for their maintenance. In research with the elderly, it was found that although the majority of the elderly have declared themselves satisfied with life, they had indicators of impairment of functional capacity and cognitive, isolated social behavior and depression, affecting the life quality of these elderly. These results reflect the need for greater investment of public power in the drafting, implementation and monitoring of public policies aimed at promoting changes that raise the level of life quality of this segment of the population

Study, a descriptive-like one, is guided by ethnographic principles which have analyzed the elderly within the familiar context in his/her process of health and aging, in the neighborhood called Felipe Camarão, located in the western administrative region of Natal, RN, a Northeastern city of Brazil. The participants are elders aging 61 to 84 years old, living in this referring neighborhood, whose majority is constituted of migrants from the rural region of the state of the RN, retired, including widows, widowers and married couples, with low school-educational degree. For the information gathering it was utilized a semi-structured interview, the participant observation and the field diary, being put into effect, in majority, in the houses and in the Family Health Unit, in a period between March and October of 2006. For the results discussion it was utilized an analysis of thematic content and the program ALCESTE (In Portuguese, Análise Léxica por Contexto de um Conjunto de Segmentos de Texto or Lexical Analysis by Context of a Set of Text Segments), which through have emerged two corpus: the corpus I, Family and the elderly, and corpus II, The elderly and the aging within society. The analysis of the results has permitted to conclude that the family, also used by the public policies as a strategy of their practices in health, it is a necessary base support for the elderly citizen in his/her process of aging and of health. The elders familiar contexts have allowed this study to identify the existence of minimal social conditions of life, of new rearrangements of the current families by means of the plurigenerational acquaintanceship and the active presence of the elderly woman as a maintainer of this family; also by means of conflicted relationships among one another but in a bearable level of acquaintanceship. Different conceptions about the aging and the elderly generate disagreement and divergency however the family support and help for the solving of these problems and the attention to health are proceeding from the family components. However, it is noticed that loneliness is something present in these elder s everyday lives. About the attention to health, in a basic level of it, it was noticed that there are still a lot of gaps, mainly concerning promotional and preventing actions, deserving a higher sensitization and effort by the local health institutions

Durante o processo de envelhecimento, as sementes sofrem alterações degenerativas que influenciam o seu potencial fisiológico. Entre estas alterações podem estar as modificações anatômicas nas camadas celulares da testa da semente. Objetivou-se, com este trabalho, verificar a relação entre a anatomia da testa de sementes de soja, cultivar Monsoy 8400 e a germinação, após o envelhecimento acelerado, pelo fato da testa apresentar um papel fundamental na conservação do potencial fisiológico das sementes. As sementes foram envelhecidas a 42ºC e 100% UR do ar por períodos de zero, 24, 48, 72 e 96 horas. Avaliaram-se os teores de água e a germinação, posteriormente à secagem, seções transversais da testa de 10 sementes de cada tratamento foram eletromicrografadas, com microscópio eletrônico de varredura,,observando-se as camadas das células paliçádicas, ampulhetas e parenquimáticas A germinação declinou com o aumento dos períodos de envelhecimento. Houve redução da espessura das camadas da testa nos períodos de 48, 72 e 96 horas deste processo. Observou-se que, principalmente, para os períodos de envelhecimento de 72 e 96 horas, que as células da camada hipodérmica apresentaram um aspecto de colapso, sendo este acentuado para o período de 96 horas. A redução da espessura das camadas sugere a ocorrência de um colapso das células que compõem tais camadas, sendo um fator causador da redução do potencial germinativo.

There are a number of damaging mechanisms that various materials can suffer in service. However, when working with polymer composite materials, this is something that requires analysis, especially when exposed to adverse environmental conditions. Thus, the objective of the present thesis is the study of the direct influence of environmental aging and the form of hybridization of the reinforcement woven on the structural stability, surfacedegradation and fracture process of polymer composites laminates. For this, the development of two polymer composite laminates was necessary, where one of them was reinforced with a bi-directional woven with hybrid strandsofkevlar-49/glass-Efibers, and the other also with a bi-directionalwoven, however with weft and warpformed of alternating strandsof Kevlar-49 fibers and glass-E fiber The reinforcementwoven are industrially manufactured. Both laminates use a polyester resin as a matrixand are made up of four layers each. All laminates were industrially prepared by the hand lay-up method of manufacturing. To do this, test specimens were manufactured of the respective laminates and submitted to environmental aging accelerated through the aging chamber. They were exposed to alternating cycles of UV radiation and moisture (heated steam) for a standard defined period. At the end of the exposure period the specimens were subjected to mechanical tests of uniaxial tensile and bending in three points and to the characterizationsof the fracture and surface deterioration. In addition, they were submitted to a structural degradation assessment by the measurement of mass variation technique (MMVT) and the measurement of thickness variation technique (MTVT), this last technique being developed in this thesis. At the end of the analysis it was observed that the form of hybridization of the reinforcement woven and the aging process directly influence with losses or gain in mechanical properties, with losses in the structural degradation and in the formation and propagation of damage mechanism of the developedcomposite laminates
