Aceitação e uso de ambiente virtual de aprendizagem no contexto de um curso de capacitação para servidores públicos

This study aimed to examine how students perceives the factors that may influence them to attend a training course offered in the distance virtual learning environment (VLE) of the National School of Public Administration (ENAP). Thus, as theoretical basis it was used the Unified Theory of Acceptance and Use of Technology (UTAUT), the result of an integration of eight previous models which aimed to explain the same phenomenon (acceptance/use of information technology). The research approach was a quantitative and qualitative. To achieve the study objectives were made five semi-structured interviews and an online questionnaire (websurvey) in a valid sample of 101 public employees scattered throughout the country. The technique used to the analysis of quantitative data was the structural equation modeling (SEM), by the method of Partial Least Square Path Modeling (PLS-PM). To qualitative data was the thematic content analysis. Among the results, it was found that, in the context of public service, the degree whose the individual believes that the use of an AVA will help its performance at work (performance expectancy) is a factor to its intended use and also influence its use. Among the results, it was found that the belief which the public employee has in the use of a VLE as a way to improve the performance of his work (performance expectation) was determinant for its intended use that, in turn, influenced their use. It was confirmed that, under the voluntary use of technology, the general opinion of the student s social circle (social influence) has no effect on their intention to use the VLE. The effort expectancy and facilitating conditions were not directly related to the intended use and use, respectively. However, emerged from the students speeches that the opinions of their coworkers, the ease of manipulate the VLE, the flexibility of time and place of the distance learning program and the presence of a tutor are important to their intentions to do a distance learning program. With the results, it is expected that the managers of the distance learning program of ENAP turn their efforts to reduce the impact of the causes of non-use by those unwilling to adopt voluntarily the e-learning, and enhance the potentialities of distance learning for those who are already users

Comparação entre os sistemas de informação adquiridos e os desenvolvidos na Força Aérea

Os Sistemas de Informação (SI) que a Força Aérea (FA) explora são maioritariamente desenvolvidos internamente mas, com a redução cada vez maior do Orçamento para a Defesa, é fundamental um maior rigor na gestão de recursos e o aproveitamento de sinergias com o mundo civil, particularmente na área das Tecnologias de Informação (TI). A decisão de optar por SI comerciais é muitas vezes determinada por aspetos como a necessidade de reduzir custos, assegurar flexibilidade ou acompanhar o desenvolvimento tecnológico. Neste contexto esta investigação tem por objeto os SI utilizados pela FA e visa verificar em que medida é mais vantajoso para a FA continuar a desenvolver os SI que explora, ou se deverá privilegiar a sua aquisição garantindo sempre o cabal cumprimento da missão. Os resultados revelam que a experiência passada com SI comerciais é negativa, os custos elevados e a satisfação dos requisitos operacionais e prazos nem sempre foram atingidos, o que conduz à conclusão que a FA deverá continuar a desenvolver SI em todas as áreas em que os requisitos internos para um SI não tenham uma afinidade forte com o que existe disponível comercialmente. Abstract: Most of the Portuguese Air Force (PoAF) Information Systems currently in use are developed in-house, but with Defence Budget cuts it is imperative that Human Resources become thoroughly managed and synergies with the civilian world are established, particularly in the Information Technology field. The decision for commercial Information Systems is most of the time determined by the need to reduce costs, assure flexibility or keep up with technology. In this context this research aims to substantiate what is more adequate for the PoAF, continue to develop its Information Systems or give way to a commercial approach , never neglecting the PoAF main goal, its mission. The results show that previous experience with commercial Information Systems have been negative, the costs were high, and the operational requisites and deadlines many times have not been fulfilled. This leads to the conclusion that the PoAF should continue to develop its Information Systems in all the areas in which a commercial solution with identical requisites cannot be found.

Recursos humanos e gestão da qualidade: "estudos de caso" em instituições particulares de solidariedade social no Concelho de Estremoz

Neste trabalho discute-se a relevância da performance nas Instituições de Solidariedade Social, com especial incidência a Gestão de Recursos Humanos, e a implementação da Gestão da Qualidade Total, na medida que se multiplicam as exigências em torno da eficiência, quantidade e qualidade dos serviços, e uma maior flexibilidade para assegurar a competitividade a nível nacional. A Gestão Estratégica de Recursos Humanos é a resposta possível e sustentada, de colocar os colaboradores no centro das Instituições, apelando à autonomia, criatividade, talento, estímulos, aspirações individuais e cooperativas, e considerar que são os colaboradores que fazem o sucesso das Instituições. Com este trabalho pretende-se chamar a atenção para a importância da GRH dentro das Instituições de Solidariedade Social, fazendo um diagnóstico da laboração na área de recursos humanos e propondo um plano de intervenção/reorganização destes mesmos serviços. Este trabalho de Dissertação segue a metodologia de três estudos de caso cuja recolha de dados foi realizada, tendo por base diversas fontes: análise documental, observação direta, questionário. Verificamos que as Instituições, objetos de estudo revelam poucos conhecimentos a nível da gestão de recursos humanos, e no que concerne à gestão da qualidade, duas das intuições não tem qualquer conhecimento, apenas a Cerciestemoz trabalha em prol da qualidade uma vez que é, uma Instituição já com vários certificados de qualidade. Face ao estudo empírico realizado constatamos que existe alguma dificuldade em prevalecer a gestão de recursos humanos e a gestão da qualidade, porque terão que estar inseridas as políticas de Gestão Recursos Humanos para que os colaboradores se sintam mais motivados e responsáveis pelas funções que desempenham, o que não é visível neste momento; ABSTRACT: This research discusses the relevance of performance in social solidarity institutions, with a focus on Human Resource Management, and the implementation of Total Quality Management, to the extent that multiply the requirements around efficiency, quantity and quality of services and greater flexibility to ensure competitiveness at national level. The Strategic Human Resource Management is possible and sustained response, placing employees at the center of the institutions, calling for autonomy, creativity, talent, stimuli, individual aspirations and cooperative skills, and consider that it is the employees that make the success of the institutions. This work is intended to draw attention to the importance of HRM in the institutions of social solidarity, making a diagnosis of laboring in the area of human resources and proposing an action plan / reorganization of these same services. This Master's work follows the methodology of three case studies in which data collection was carried out, based on several sources: document analysis, direct observation, questionnaire. We found that the institutions, objects of study reveal little knowledge in the management of human resources, and with regard to quality management, two of intuitions do not have any knowledge, only Cerciestemoz works for the quality since it is a institution already with several quality certificates. Given the empirical study found that there is some difficulty prevail human resource management and quality management, they will have to be inserted the policies of Human Resources Management for employees and feel more motivated and responsible for the functions they perform, the which is not visible at this time.

High protein flexibility and reduced hydration water dynamics are key pressure adaptive strategies in prokaryotes

Water and protein dynamics on a nanometer scale were measured by quasi-elastic neutron scattering in the piezophile archaeon Thermococcus barophilus and the closely related pressure-sensitive Thermococcus kodakarensis, at 0.1 and 40 MPa. We show that cells of the pressure sensitive organism exhibit higher intrinsic stability. Both the hydration water dynamics and the fast protein and lipid dynamics are reduced under pressure. In contrast, the proteome of T. barophilus is more pressure sensitive than that of T. kodakarensis. The diffusion coefficient of hydration water is reduced, while the fast protein and lipid dynamics are slightly enhanced with increasing pressure. These findings show that the coupling between hydration water and cellular constituents might not be simply a master-slave relationship. We propose that the high flexibility of the T. barophilus proteome associated with reduced hydration water may be the keys to the molecular adaptation of the cells to high hydrostatic pressure.

Estágio realizado no Programa Comunitário PLE²NO

A OA é a doença reumática mais comum no ser humano e uma doença crónica com impacto elevado na sociedade. Tem repercussões na saúde, ao nível da funcionalidade, comprometendo a realização das atividades da vida diária e a qualidade de vida dos indivíduos. Uma das articulações mais afetada pela OA é a articulação do joelho. O tratamento eficaz requer a combinação de tratamentos farmacológicos e não farmacológicos. Os tratamentos não farmacológicos, principalmente o exercício e a educação do doente têm vindo a ganhar importância, no que se refere ao controlo dos sintomas. A realização do estágio curricular surge no programa comunitário PLE²NO. O programa é considerado uma opção não farmacológica no tratamento e controlo dos sintomas da Osteoartrose (OA) no joelho. Os principais objetivos do estágio no PLE²NO consistiram: aquisição de conhecimentos teóricos relacionados com OA e práticos com vista ao aperfeiçoamento da prescrição do exercício; aquisição de competências essenciais à ótima liderança e comunicação com as pessoas e instituições envolvidas; prescrição de exercício a indivíduos com OA no joelho; cativar e motivar as pessoas para a prática de exercício; e determinar a eficácia de um programa de 3 meses de educação e exercício nos sintomas, aptidão física e qualidade de vida dos idosos com OA no joelho. Na aptidão física verificaram-se diferenças significativas na capacidade aeróbia, flexibilidade e velocidade da marcha. Nos indicadores de saúde houve melhoria em praticamente todos os parâmetros avaliados: mobilidade, cuidados pessoais, dor/mal-estar e sintomas de ansiedade/depressão. Assim, esta intervenção revelou-se ser uma mais-valia para o tratamento não farmacológico da osteoartrose do joelho a médio prazo.

Simulador radiográfico antropomórfico de mama humana

Mammography is a diagnostic imaging method in which interpretation depends on knowledge of radiological aspects as well as the clinical exam and pathophysiology of breast diseases. In this work a mammography phantom was developed to be used for training in the operation of mammographic x-ray equipment, image quality evaluation, self-examination and clinical examination of palpation. Polyurethane was used for the production of the phantoms for its physical and chemical properties and because it is one of the components normally used in prostheses. According to the range of flexibility of the polyurethane, it was possible to simulate breasts with higher or lower amount of adipose tissue. Pathologies such as areolar necrosis and tissue rejection due to surgery reconstruction after partial mastectomy were also simulated. Calcifications and nodules were simulated using the following materials: polyethylene, poly (methyl methacrylate), polyamide, polyurethane and poly (dimethyl silicone). Among these, polyethylene was able to simulate characteristics of calcification as well as breast nodules. The results from mammographic techniques used in this paper for the evaluation of the phantoms are in agreement with data found in the literature. The image analyses of four phantoms indicated significant similarities with the human skin texture and the female breast parenchyma. It was possible to detect in the radiographic images produced regions of high and low radiographic optical density, which are characteristic of breasts with regions of different amount of adipose tissue. The stiffnesses of breast phantoms were adjusted according to the formulation of the polyurethane which enabled the production of phantoms with distinct radiographic features and texture similar to human female breast parenchyma. Clinical palpation exam of the phantoms developed in this work indicated characteristics similar to human breast in skin texture, areolar region and parenchyma

Effects of roller massager on muscle performance, morphology, and oxygenation after exercise-induced muscle damage

This study determined roller massager (RM) effectiveness on ankle plantar flexors’ recovery after exercise-induced muscle damage (EIMD) stimulus. Two experiments were conducted. The first experiment (n=10) examined functional [i.e., ankle plantar flexion maximal voluntary isometric contraction (MVIC) and submaximal (30% of MVIC) sustained force; ankle dorsiflexion maximal range of motion and resistance to stretch; and pain pressure threshold] and morphological [medial gastrocnemius (MG) cross sectional area, thickness, fascicle length, and fascicle angle] variables, before and immediately, 1h, 24h, 48h, and 72 after EIMD. In the second experiment (n=10), changes in MG deoxyhemoglobin concentration kinetics (velocity and amplitude) during a submaximal sustained force test were observed before and 48h after EIMD. Participants performed both experiments twice, with and without (NRM) the application of a RM (6 × 45 seconds with 20 seconds rest between sets). RM intervention did not alter plantar flexors’ strength and flexibility impairment after EIMD, as well the MG morphology and oxygenation kinetics (p>0.05). On the other hand, a strong tendency for an acute (within 1 hour) change of ipsilateral (post-effects: RM=+19%, NRM=-5%, p=0.032) and contralateral (p=0.095) MG pain pressure threshold was observed. In conclusion, the present results suggest that a roller massager has no effect on muscular performance, morphology, and oxygenation recovery after EIMD, except for muscle pain pressure threshold (i.e., a soreness). Thus, RM may have potential application in recovery for people with increased muscle soreness, if performed immediately before a physical task.

UBS RN-7: proposta arquitetônica para um padrão flexível de unidade básica de saúde para a zona bioclimática 7 do RN, com ênfase na sustentabilidade ambiental

Standardization and sustainability: these two apparently antagonistic words find the challenge of uniting in a flexible architectonic proposal. This was the idea that motivated the proposal of this assignment, whose appearing is bound up with the necessity of thinking about standardized spaces that attend on functional criterias and environmental sustainability, in reply to an existing real demand. The assignment consists of an architectonic proposal for a flexible standard of a Basic Unit of Health for the bioclimatic zone 7 of RN (UBS RN-7), with emphasis in the environmental sustainability. The project contemplates innumerable involved variables, such as: obedience to the current law of the Health Ministry for the UBSs; formal/aesthetic aspects; criterias of expansiveness of the UBS I for the UBS II; relative aspects to the constructive rationality and, mainly, sustainability aspects. With the intention to unite the variables and, also, glimpsing a proposal that could reach a good functional performance, aesthetic, of environment comfort and energetic efficiency, it was also necessary to consider concepts about the flexibility of the envelopment. The elaboration of the architecture first draft was based on bibliographical research, conceptual studies and references, elaboration of the architectonic program and the draft development for the UBS port I and the UBS port II. To the end, an implantation data sheet for the project is proposed for the UBS standard project, where strategies of thermal isolation, shadowing and thermal inertia are adopted and combined to three possible types of lot, resulting in 24 possibilities of implantation

Fachada flexível para casa padronizada em condomínios

The employment of flexibility in the design of façades makes them adaptable to adverse weather conditions, resulting in both minimization of environmental discomfort and improvement of energy efficiency. The present study highlights the potential of flexible façades as a resource to reduce rigidity and form repetition, which are usually employed in condominiums of standardized houses; as such, the work presented herein contributes to field of study of architectural projects strategies for adapting and integrating buildings within the local climate context. Two façade options were designed using as reference the bionics and the kinetics, as well as their applications to architectural constructions. This resulted in two lightweight and dynamic structures, which cater to constraints of comfort through combinations of movements, which control the impact of solar radiation and of cooling in the environment. The efficacy and technical functionality of the façades were tested with comfort analysis and graphic computation software, as well as with physical models. Thus, the current research contributes to the improvement of architectural solutions aimed at using passive energy strategies in order to offer both better quality for the users and for the sustainability of the planet
