A criatividade tem tomado um papel relevante na sociedade contemporânea adquirindo, cada vez mais, uma posição de realce sobretudo no mundo laboral. O aumento da curiosidade científica em torno desta levou à descoberta dos estilos de pensar e criar. Estes pressupõem uma interacção entre o intelecto e a personalidade e conhecê-los tornou-se um dos objectivos dos investigadores que iniciaram o seu estudo, desenvolvendo uma escala com o intuito de avaliá-los. O objectivo desta investigação consiste na adaptação duma escala de estilos de pensar e criar à população adulta portuguesa. Participaram 331 sujeitos, 58,1% do sexo feminino e 41,9% do sexo masculino. A versão final desta escala é composta por 49 itens com um alpha de Cronbach de 0,91.A análise factorial demonstrou a existência de cinco factores: inconformista/transformador, emocional/intuitivo, relacional divergente, independência de julgamento e lógico/objectivo, com índices de fiabilidade que variam entre 0,59 e 0,85.Verificaram-se diferenças significativas na classe etária, onde indivíduos com mais de 25 anos apresentaram médias superiores em todos os factores relativamente a indivíduos com idades entre os 17 e 24 anos; nas habilitações literárias, na qual indivíduos com licenciatura e pós-licenciatura revelaram médias superiores em alguns dos factores comparativamente a indivíduos com o secundário e na profissão, onde os docentes exibiram médias superiores para alguns dos factores relativamente a discentes e funcionários. Globalmente, a versão final da escala apresenta bons valores de validade, contudo, novos estudos, de carácter confirmatório, são necessários.

Este estudo avalia as dimensões do engagement que os professores utilizam para lidar com o seu trabalho docente. Para a avaliação das dimensões utilizou-se a Utrecht Work Engagement Scale (UWES) elaborada por Schaufeli e Bakker (2003), distinguindo-se as variáveis vigor, dedicação e absorção. Os resultados obtidos nesta investigação (N=54) coincidem com estudos anteriores quanto à consistência interna das três subescalas, que é estável e satisfatória. Revelam também que a UWES apresenta-se como um instrumento válido e adequado para ser utilizado em investigações futuras.

Os tempos livres na escola, nomeadamente intervalos e hora do almoço são uma oportunidade para a promoção de um estilo de vida ativo. Neste contexto, foram objetivos desta investigação: (i) adaptar o sistema de observação SOPLAY; (ii) caraterizar os níveis de atividade física geral (AFg) nos intervalos das aulas (AF_Int) e hora do almoço (AF_Alm), e (iii) apresentar uma proposta de intervenção para a promoção da AF naqueles períodos. O sistema de observação SOPLAY (Mckenzie et al., 2006) é um instrumento validado para caraterizar os níveis de AF durante os intervalos. Assim, numa 1ª fase procedeu-se à adaptação do protocolo do sistema de observação, treino da equipa de observadores e determinação da fiabilidade inter e intraobservadores. Numa 2ª fase, procedeu-se à avaliação dos níveis de AFg de 555 rapazes e raparigas (9 a 17 anos de idade) de duas escolas de 2º e 3º Ciclos da RAM, através do questionário PAQ-C (Crocker et al., 1997). Posteriormente, procedeu-se à observação, caraterização e análise do envolvimento institucional e perfil de atividade física. Os resultados obtidos na fiabilidade da adaptação do SOPLAY mostram uma elevada consistência inter- (CCI: 0,850 - 0,994) e intra-observador (CCI: 0,665 - 0,977), e entre os elementos da equipa de observadores e o observador de referência (CCI: 0,831 - 0,976). Os rapazes em média reportaram níveis de AFg superiores comparativamente às raparigas (2,80 ± 0,64 vs 2,19± 0,52, respetivamente). Nos intervalos, os alunos optam maioritariamente por atividades sedentárias (75,2%), estando caraterísticas do envolvimento institucionais, como disponibilidade de equipamentos e tipologia das áreas (formais), associadas a um perfil mais ativo (p<0,05). Atendendo à influência do envolvimento institucional nos níveis de AF, desenhou-se uma proposta de programa de intervenção focalizado no (i) envolvimento físico e (ii) envolvimento político escolares-

O desporto é um meio que contribui para a transformação do Homem, por isso é preciso entender as atividades desportivas como instrumentos que solicitam comportamentos que ajudam na relação dialógica que o Homem tem com o contexto. De uma forma global é retratado o contexto atual da sociedade, do desporto, do turismo, da educação e dos DAM. Depois é aprofundado mais especificamente o interesse, potencialidades e constrangimentos na integração dos DAM na escola. É dado especial ênfase ao contexto específico da RAM pela sua pertinência ao nível dos seus atributos naturais bem como no setor estratégico do turismo. Defende-se que é possível ultrapassar constrangimentos e criar um produto do conhecimento específico dos DAM, pelo que é construído a título exemplificativo uma situação de Orientação limitada ao contexto escolar. Neste sentido coloca-se à refutação três aspetos essenciais. A operacionalidade da situação criada, através de uma situação exemplificativa aplicada a uma escola de 1.º ciclo da RAM. A recetividade do produto por parte dos professores e por fim as possibilidades de implementação de uma estrutura de apoio nas escolas para a construção deste tipo de produtos. Conclui-se que é possível construir, aplicar e avaliar na escola produtos do conhecimento específico dos DAM, que se pode identificar variáveis por parte dos professores que implicam na recetividade a estes produtos e que existem mecanismos legais de implementação de uma estrutura de apoio para professores que queiram implementar um produto com as características da proposta apresentada e possivelmente participar num projeto de implementação mais vasto.

This is a study concerning in the structure of non governmental organizations, based on the institutional theory. It aims to understand the relation among structure, social projects and environmental influences, analyzing if there is coherence with project social or expresses adaptation to the institutional pressures of the environment. It introduces as theoretical support for the themes, studies about institutional theory and social structure. The research is descriptive and exploratory; it also applies to a study of case, based on the technical procedures. From the research universe, that was compound by non governmental organizations from Natal, RN, Brasil, it was chosen the Casa Renascer, a non governmental organization that works with the combat to the violence and sexual exploration of children and teenagers. The data collection process employed includes documental research, observations and semi structured research devices, guided by the organizational process proposed by Serva (1996) and by the institutional theory. The collected data were qualitatively treated. The analysis was divided into three parts, following the research matters. The social project characterization demonstrated that the organization went by three main phases. The first one, characterized by focus in women and girls education and health; the second shows the emphasis on girls in social risk situation, with preventive approach; and the last one, characterized by victims assistance of violence and sexual exploration. From the analysis using the institutional theory mechanisms, the results showed that exists coherence between structure and environmental influences, but a weak coherence between structure and social projects. It indicates as main determinant of the structure, an aspect forgotten by the institutional theory, the power. It was observed the presence from normative, coercive and mimetic mechanisms, highlighting normative influences

The present study had as objective translates, to do equivalence and validation of the Utian Quality of Life (UQOL) for the Brazilian population through methods internationally accepted, in which the original questionnaire was translated for the Portuguese by three teachers and the consensual version was translated back for English by two American teachers (back translation). A multidisciplinary committee evaluated all versions and the final version in Portuguese was applied to climacteric women for the process of adaptation. Validation of the instrument was performed by measuring the reliability and validity properties. Construct validity was examined through the comparison between UQOL and the general measuring scale of quality of life Short Form-36 (SF-36). The final version of translation process was easily recognized by the target population, that didn't tell understanding problems. The results obtained for the reliability intra and interobserver showed significant agreement in all of the subjects. The construct validity was obtained through correlations statistically significant among the domains occupational, health and emotional of UQOL with the SF-36 domains. For the exploratory factorial analysis, it was verified that three factors explain 60% of the total variance of the data, the present study allowed concluding that UQOL was appropriately translated and adapted for applicability in Brazil, presenting high reliability and validity. In that way, the executed project provided the involvement of different areas as gynecology, psychology and physiotherapy (interdisciplinary). Thus, this instrument can be included and used in Brazilian studies to assessment the quality of life during the climacteric years

Introdução: Os hormônios estrogênicos possuem importante papel na defesa contra as espécies reativas do oxigênio, fato que se evidencia na maior incidência de doenças cardiovasculares e neurodegenerativas após a menopausa. O exercício físico melhora as defesas antioxidantes, contudo em altas cargas e em baixas concentrações de estrógeno possui efeito aditivo ao dano oxidativo. O ácido α-lipóico possui uma ampla gama de ação antioxidante e poderia contribuir para diminuição do dano nestas condições. Objetivo: O objetivo deste estudo é caracterizar a ação do ácido α-lipóico sobre a adaptação antioxidante e funções reprodutivas de ratas submetidas a natação moderada. Material e métodos: Os animais foram submetidos a natação diária (1 hora) e sacrificados após 30, 60 e 90 dias. Os animais foram divididos em controles sedentários e exercitados; suplementados (ácido α-lipóico 100mg/Kg/dia) sedentários e exercitados e animais ovariectomizados e suplementados com ácido lipóico. Avaliou-se diariamente o ciclo estral e os seguintes marcadores de estresse oxidativos foram mensurados em fígado e sangue: atividade enzimática da SOD, GPx e CAT, além do SRAT e GSH. Resultados: O protocolo de exercício aumentou a duração do ciclo estral no grupo controle exercitado, sobretudo na fase diestral. Neste mesmo grupo, houve diminuição da lipoperoxidação com melhora da atividade antioxidante da SOD e GPx. O grupo exercitado e suplementado não apresentou alteração na duração do ciclo estral e manteve os benefícios sobre o sistema antioxidante antes observado nos animais exercitados. A suplementação antioxidante juntamente com a natação em períodos superiores a 30 dias, diminuiu o processo de adaptação antioxidante quando comparado aos animais somente exercitados. Nos animais ovariectomizados, o exercício e a suplementação com ácido lipóico não promoveu adaptação antioxidante ao contrário dos demais grupos. Conclusão: O aumento na duração do ciclo estral e a melhora nos marcadores de estresse oxidativo seriam uma resposta adaptativa frente ao exercício moderado. O ácido lipóico impediu a alteração no ciclo induzida pelo exercício, mas preservou a melhoria no sistema antioxidante. A depleção estrogênica provocada pela ovariectomia eleva o potencial de dano oxidativo gerado pelo exercício. A ação antioxidante do LA na presença de estrógeno diminuiu excessivamente o dano oxidativo, comprometendo a adaptação antioxidante a natação. Nos animais ovariectomizados, contudo, o AL promoveu adaptação antioxidante ao exercício

O Activities daily living questionnaire - ADLQ foi elaborado para avaliar atividades básicas e instrumentais em pacientes com a doença de Alzheimer. O objetivo principal deste estudo consistiu em realizar a tradução do ADLQ para a língua portuguesa, adaptação transcultural e análise das suas propriedades psicométricas. A amostra foi composta por 60 pacientes e os respectivos 60 cuidadores. O estudo iniciou-se com a tradução do instrumento pela técnica de retrotradução associada ao método bilíngüe. A versão traduzida foi respondida pelo cuidador e o Mini Exame do Estado Mental (MEEM) aplicado ao paciente. A análise psicométrica foi realizada através da validade das medidas do instrumento. Os resultados verificaram uma correlação inversamente significativa (r=-0,793;p<0,05) entre os instrumentos avaliados, com uma explicação da variância total de 62%. A coerência interna do instrumento foi realizada através da correlação com os resultados do MEEM sugerindo uma versão condensada do ADLQ. Avaliando-se através do teste t para amostras correlacionadas, as médias do ADLQ-versão traduzida e versão condensada não apresentaram diferenças significativas, demonstrado assim que a simplificação do instrumento não alterou os valores do nível de dependência funcional observados. A análise fatorial realizada através da rotação Varimax indicou seis dimensões. Atividades como; comer, vestir-se, banho, necessidades fisiológicas, tomar comprimidos, participação em grupos, administrar finanças, manusear dinheiro, locomover pela vizinhança, usar telefone, compreensão, dentre outras, são os mais importantes preditores da capacidade funcional, no grupo estudado. Atividades com desempenho pouco comum a ambos os sexos, e no desempenho de papéis sociais enquanto gênero na sociedade brasileira (afazeres domésticos, consertos e manutenção em casa), na amostra estudada, não demonstraram ter importância na determinação da capacidade funcional com o paciente com a Doença de Alzheimer. O presente estudo disponibiliza uma nova ferramenta de avaliação funcional, visando contribuir para a mensuração mais cuidadosa do estado funcional do paciente por todos os profissionais da área da saúde

Post-menopause is a period of women s life cycle that is characterized by estrogen depletion and therefore increasing cardiovascular diseases, neurodegenerative disorders, urogenital atrophy, osteoporosis, hot flushes and sexual discomfort incidences. Estrogen is a hormone with comfirmed antioxidant action and its depletion is related to oxidative stress instalation and damaging various important biomolecules. Regular physical activity has been identified as a factor involved in reducing women s post-menopausal complications in addition to improving antioxidant defense by reducing the oxidative damage and consequently improving life s quality in this part of the population. This study aims to evaluate the influence of hypoestrogenism in antioxidant adaptation due to regular exercise, by determining reduced glutathione (GSH) and Thiobarbituric Acid Reactive Substances (SRAT) concentrations and antioxidant enzymes glutathione peroxidase (GPx), Superoxide Dismutase (SOD) and Catalase (CAT) activities in blood, brain and liver of rats. To achieve this goal we used 50 Wistar rats, weighing 180-250g which were divided into two groups, control - GC (25) and ooforectomized - GO (25). Each group was subdivided into five subgroups: Not-trained - S (5), Not-trained Acute Exercise - SEA (5), regular exercise 30 days - E30 (5), regular exercise 60 days - E60 (5) and regular exercise 90 days - E90 (5). Each of the three subgroups exercised regularly was subjected to acute exercise on the eve and the day of sacrifice to collect biological samples of blood, liver and brain and subsequent determination of SRAT concentration, GSH content and antioxidant enzymes GPx, SOD and CAT activities. The results indicated that the sedentary animals acutely exercised presented oxidative stress and regular physical activity led to antioxidant adaptation. In ooforectomized group the antioxidant adaptation seen in control animals showed to be impaired. Unlike the results from blood and liver, in brain there was a shield against oxidative damage originated by the exercise and that hypoestrogenism led to a loss of this natural antioxidant potential. Therefore, hypoestrogenism interferes negatively in antioxidant adaptation due to regular exercise

This study aims to analyze and compare the opinion of professionals, managers and users about the mental health care in the Family Health Strategy (FHS). It is characterized as an Operations Research or Health System Research with a cross-sectional design and a descriptive quantitative nature. The study was developed from the application of the Opinion Measurement Scale allied to techniques of observation and structured interview in the city of Parnamirim / RN. The sample consists of 409 subjects, 209 professionals of the Family Health Strategy, 30 of the Oral Health Strategy, 19 of the Family Health Support Center, 24 directors of Basic Health Units, plus 68 users with mental disorders and 59 caregivers, respecting the ethical parameters of Resolution 196/96 of the National Health Council, trial registration number: CAAE 0003.0.051.000-11. Quantitative data were submitted to the Epi-info 3.5.2 for analysis. The network of mental health in Parnamirim involves the flow between the FHS, Psychosocial Care Centers, clinics and hospitals, having as main barriers the fragility of the referral and counter-referral system, of the municipal health conferences, of the FHS teams by the limitations in material and human resources as well as the population´s lack of acknowledge about the organization of the mental health network, issues that affect the integral attention. Even though the FHS professionals recognize the importance of their actions, they question their role in mental health care, experiencing difficulties in accessing psychiatric services (76.5%). Although most agree that the mentally ill is best treated in the family than in hospital (65.2%), the community health workers were the predominant category in the partial or total disagreement of this statement (40.8%), who is the professional in greater contact with the family. Nevertheless the caregivers miss the support of the FHS as the main focus of attention is on revenue control. The views of professionals, mental patients and caregivers converged in several statements, showing the main weaknesses to be focused by the mental health network of the city, as the perceptions that: (a) physical strength is needed to take care of mental patients for its tendency to aggression, requiring it to stay in the sanatorium for representing danger to society, (b) only a psychiatrist can help the person with emotional problems, (c) the user of alcohol and drugs does not necessarily develop mental illness, (d) the access barriers and doubts about the quality of psychiatric services, (e) caring of a mental health patient does not bring suffering to professionals. Therefore, the commitment to consensus building, monitoring and evaluation of the network are important mechanisms for an effective management system, reflecting in the importance of strengthening the health conferences and approximating different institutions. The results reinforce the importance of strengthening primary care through programs of continuing education focusing on the actions and functions of professionals in accordance with its competences and duties what contribute to the organization and response of mental health care, favoring user´s care and the promotion of family health

The nurses in the hemodialysis has an important role in the nursing process implementation, in the context of a theoretical referential. Among the nursing theories, highlights the Roy´s adaptations model, who considers a person as an holistic adaptive system that aims to adapt customers to different living conditions. Thus, it is believed that the Roy´s nursing process will guide nursing care to patients on dialysis. Therefore, the study aimed to analyze the nursing diagnosis present in patients with chronic kidney disease on hemodialysis based on the theoretical model of Roy and NANDA-International. Descriptive and cros-sectional study, performed at a dialysis center in a city in northeastern Brazil. Sample of 178 patients and consecutive sampling by convenience. Data collection ocurred from October/2011 until February/2012, through interview and physical examination forms. Data analysis was initiated by clinical reasoning, diagnosis judgment and similarity relation. Then, the data were entered into SPSS program, 16.0 version, generating descriptive statistics. The project was approved by the Ethics Research Committee (protocol nº 115/11) with a Presentation Certificate for Ethics Appreciation (in 0139.0.051.000-111) and was funded by the Universal edict MCT / CNPq 14/2010. The results revealed that most patients were male (52.2%), married (62.9%) and residents in the Natal´s metropolitan region (54.5%). The mean age was 46.6 years and the years of study, 8,5. Regarding nursing diagnosis obtained an average of 6.6, especially: Risk of Infection (100%), excessive fluid volume (99.4%) and hypothermia (61.8%). On the other hand the adaptive problems average was 6.4, and the most common: intracellular fluid retention (99.4%); Hyperkalemia (64.6%); Hypothermia (61.8%) and edema (53.9%). Were established 20 similarity relations between the NANDA-International nursing diagnosis and adaptive problems of Roy, namely: risk of falls / injury risk and potential for injury, impaired physical mobility and walking mobility and / or restricted coordination, dressing self-care deficit and loss of self-care ability; hypothermia and hypothermia; impaired skin integrity and impaired skin integrity; excessive fluid volume and intracellular fluid retention / Hyperkalemia / Hypocalcemia / edema; imbalanced nutrition: less than body requirements and Nutrition less than the body's needs; constipation and constipation, acute pain and acute pain, chronic pain and chronic pain, sensorial perception disturbed: visual, tactile and auditory disabilities and a primary sense: sight, hearing and tactile; sleep deprivation and insomnia, fatigue and intolerance to activities; ineffective self health and fails in the role; sexual dysfunction and sexual dysfunction; situational low self-esteem and low self-esteem, and diarrhea and diarrhea. We conclude that there is similarity between the typologies and was required a model´s analysis, because they present different ways to establish the nursing diagnosis. Moreover, the nursing process use, under the context of a theory and a classification system, subsidizes the care and contributes to the strengthening of nursing science

Investigaram-se a temperatura retal, a freqüência respiratória e a taxa de evaporação total de ovinos Corriedale sob três temperaturas ambientes, visando uma melhor compreensão dos mecanismos de termorregulação desses animais. Inicialmente, 21 animais adultos foram alojados em câmara climática à temperatura de 45ºC, e pressão parcial de vapor (PV) variável, registrando-se a freqüência respiratória (FR) e a temperatura retal (TR). Baseando-se na FR e TR, foram selecionados 10 animais, cinco com os valores mais baixos, assumindo-os como mais adaptados ao calor (grupo 1) e cinco com valores mais altos, assumindo-os como menos adaptados (grupo 2). Os animais selecionados foram mantidos em câmara climática, onde mediram-se novamente TR, FR e taxa de evaporacão total (TET), sob 20, 30 e 40ºC de temperatura do ar e PV variável. Não houve diferença estatística entre os grupos classificados, para todas as variáveis medidas. Concluiu-se que a utilização das variáveis fisiológicas TR e FR como parâmetros únicos para a seleção destes animais não é suficiente para avaliar o grau de adaptação a temperaturas elevadas.

In academia, it is common to create didactic processors, facing practical disciplines in the area of Hardware Computer and can be used as subjects in software platforms, operating systems and compilers. Often, these processors are described without ISA standard, which requires the creation of compilers and other basic software to provide the hardware / software interface and hinder their integration with other processors and devices. Using reconfigurable devices described in a HDL language allows the creation or modification of any microarchitecture component, leading to alteration of the functional units of data path processor as well as the state machine that implements the control unit even as new needs arise. In particular, processors RISP enable modification of machine instructions, allowing entering or modifying instructions, and may even adapt to a new architecture. This work, as the object of study addressing educational soft-core processors described in VHDL, from a proposed methodology and its application on two processors with different complexity levels, shows that it s possible to tailor processors for a standard ISA without causing an increase in the level hardware complexity, ie without significant increase in chip area, while its level of performance in the application execution remains unchanged or is enhanced. The implementations also allow us to say that besides being possible to replace the architecture of a processor without changing its organization, RISP processor can switch between different instruction sets, which can be expanded to toggle between different ISAs, allowing a single processor become adaptive hybrid architecture, which can be used in embedded systems and heterogeneous multiprocessor environments

The hardness test is thoroughly used in research and evaluation of materials for quality control. However, this test results are subject to uncertainties caused by the process operator in the moment of the mensuration impression diagonals make by the indenter in the sample. With this mind, an automated equipment of hardness mensuration was developed. The hardness value was obtained starting from the mensuration of plastic deformation suffered by the material to a well-known load. The material deformation was calculated through the mensuration of the difference between the progress and retreat of a diamond indenter on the used sample. It was not necessary, therefore, the manual mensuration of the diagonals, decreasing the mistake source caused by the operator. Tension graphs of versus deformation could be analyzed from data obtained by the accomplished analysis, as well as you became possible a complete observation of the whole process. Following, the hardness results calculated by the experimental apparatus were compared with the results calculated by a commercial microhardness machine with the intention of testing its efficiency. All things considered, it became possible the materials hardness mensuration through an automated method, which minimized the mistakes caused by the operator and increased the analysis reliability

Due to advances in the manufacturing process of orthopedic prostheses, the need for better quality shape reading techniques (i.e. with less uncertainty) of the residual limb of amputees became a challenge. To overcome these problems means to be able in obtaining accurate geometry information of the limb and, consequently, better manufacturing processes of both transfemural and transtibial prosthetic sockets. The key point for this task is to customize these readings trying to be as faithful as possible to the real profile of each patient. Within this context, firstly two prototype versions (α and β) of a 3D mechanical scanner for reading residual limbs shape based on reverse engineering techniques were designed. Prototype β is an improved version of prototype α, despite remaining working in analogical mode. Both prototypes are capable of producing a CAD representation of the limb via appropriated graphical sheets and were conceived to work purely by mechanical means. The first results were encouraging as they were able to achieve a great decrease concerning the degree of uncertainty of measurements when compared to traditional methods that are very inaccurate and outdated. For instance, it's not unusual to see these archaic methods in action by making use of ordinary home kind measure-tapes for exploring the limb's shape. Although prototype β improved the readings, it still required someone to input the plotted points (i.e. those marked in disk shape graphical sheets) to an academic CAD software called OrtoCAD. This task is performed by manual typing which is time consuming and carries very limited reliability. Furthermore, the number of coordinates obtained from the purely mechanical system is limited to sub-divisions of the graphical sheet (it records a point every 10 degrees with a resolution of one millimeter). These drawbacks were overcome by designing the second release of prototype β in which it was developed an electronic variation of the reading table components now capable of performing an automatic reading (i.e. no human intervention in digital mode). An interface software (i.e. drive) was built to facilitate data transfer. Much better results were obtained meaning less degree of uncertainty (it records a point every 2 degrees with a resolution of 1/10 mm). Additionally, it was proposed an algorithm to convert the CAD geometry, used by OrtoCAD, to an appropriate format and enabling the use of rapid prototyping equipment aiming future automation of the manufacturing process of prosthetic sockets.
