Nowadays the acquisition of sustainable elements and concepts in construction has been increasingly discussed, improved and incorporated to buildings, since the sector directly interferes in the urban space and environment, representing environmental impact. In order to make a sustainable building (Green Building) it is vital to incorporate less damaging constructive practice, starting from the project until the operation of the enterprise, that means to consider an integrated process of conception, implementation, construction and operation. The more effective sustainable principles participation in architecture happens at the projecting step through minimal environment impact solutions. Among the issues varieties that goes with sustainability proposal of the buildings project, there were added to this work the elements that are directly attached to bioclimatic architecture, more specifically the climate variation, ventilation, lighting and sunlight, that directly affect the project conception. It is important to put in evidence that architecture role goes far beyond the simple activity of building spaces; it is the sequence of political, economic, social and cultural elements, having the users as the main apparatus to its materialization. Thereby this professional dissertation consists of an architecture draft for a professional and technological school in the Rio Grande do Norte State, this dissertation is based on the analysis of previous experience and the bioclimatic principles that implicate in building on hot and dry, hot and humid climates, and the use of strategic solutions that aim the optimization of natural light and ventilation

This paper is set in a scenario in which higher education institutions suffer from external pressure to increase efficiency. The legislation after the Law of Directives and Bases for Education (LDBE), from 1996, is characterized by the fragmentation in its implementation, raising a concern with flexibility and innovation in several normative devices as well as aspects that must be incorporated to its organizational structure. The policies examined in this thesis are: Distance Education (DE); Law of Innovation and the Program of Support to Restructuring and Expansion of Federal Universities (PSREFU). This thesis aims to observe to what extent the characteristics of innovation and flexibility, which mark the new post- LDBE educational legislation, influence the organizational redesign of the Federal University of Ceará (UFC). For being about implementation policies, using contingency approach in order to collect the internal dynamics permeating the redesign of higher education institutions, the thesis focuses on the impacts caused by flexibility and innovation. This is a qualitative research, with case study methods, archive research and semi-structured interviews with members of the university administration. The results don t allow us to confirm the adoption of a more flexible and innovative configuration in the university but it is possible to identify the presence of those elements in the implementation changes, characterizing the hybrid structure. The changes mainly expose the extension of the management of projects to the administrative and academic components related to the institution. In terms of projection, the study found changes in the elements which characterize the current setting and the tendency of the university for adopting a diverse organizational structure. However, if the decentralization of management persists, the academic units may adopt their own structural solutions, but with no evidence of changes in the professional organization in most units. In this perspective, this thesis states that there are difficulties when incorporating innovation and flexibility to their organizational structure, which lead to improvised solutions, superposing skills through the redundancy of structures created with the same purpose or copying exogenous solutions

In recent years, the Universidade Federal do Rio Grande do Norte (UFRN) has come through an intense process of expansion, common for the Instituições Federais de Ensino Superior (IFES) - Higher Education Institutions – since the implantation of the Programa de Reestruturação e Expansão das Universidades Federais (REUNI), a program of restructuring and expansion of the federal universities. The incentives made at UFRN can be seen into the expansion of the fields of teaching, research and extension, besides hiring human resources and adaptation / expansion of physical spaces. The focus of the UFRN at the technological area through the project (REUNI) has reflected in a significant expansion of the physical structure of the Center of Technology, area where the section of classes IV remains being the main set of rooms that supports the demand of the courses in the technological area, in which highlights the lack of classrooms. In this sense, the work presented here, proposes an architectural blueprint for expanding the physical space of this sector, based in this main parameters: (i) the spatial flexibility that attends the varying numbers of students per class; (ii) the environmental comfort, using the parameters and guidelines constructive for the Bioclimatic Zone 8; (iii) the requirements contained in the rules of ABNT NBR 9050:2004, 9077:2001 and NBR NBR 15220-3:2003. The architectural proposal used the maximum template allowed by the UFRN Central Campus Master Plan, four floors, considering the existing building (area equal to 7413.95 m²) as the ground floor and the extension proposed distributed on three floors, with an area of around 2,535, 00 m² each, making up a total of 7602.65 m² of total area built

This research examined the personnel policies of the Federal University of Pará (UFPA), aimed at the middle area, implemented by the President's Office of Personnel Management (PROGEP), through the Performance Management and Development from 2006 to 2009 period, in which Institutional Plan was implemented for Technical and administrative (PIDT) with a view to ascertaining whether these actions were developed in line with the ideas of managerialism or New Public Management (NPM). The study opted for qualitative research using interview as a tool to collect data. The informants were managers PROGEP / UFPA who acted in that period. Data interpretation was based on analysis of content from the collation of speeches and documents produced during the period with the managerial categories. Data analysis revealed that the management of people, UFPA has the characteristics of a hybrid management, observing the period studied two models of management: a bureaucratic, rational, focused on processes, contemporary face of public organizations, and other managerialist, adopted by PROGEP in obedience to the mandatory policies of the federal government, being much more present the characteristics of a personnel policy-oriented processes. Concludes that the personnel policy of the UFPA has not been fully tuned to managerialism in the surveyed period

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

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

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

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

Os poços HPHT atravessam zonas anormalmente pressurizadas e com altos gradientes de temperatura. Esses poços apresentam elevadas concentrações de tensões produzidas pelas operações de perfuração e fraturamento hidráulico, flutuações da pressão e temperatura, forças dinâmicas geradas durante a perfuração, formações inconsolidadas, entre outros aspectos, podendo resultar em falhas mecânicas na bainha de cimento. Tais falhas comprometem a estabilidade mecânica do poço e o isolamento das zonas produtoras de óleos e/ou gás. Para que operações corretivas não se façam necessárias, é preciso adequar as pastas às condições de cada poço. Sistemas de pastas de cimento para poços HPHT requerem um bom controle de suas propriedades termo-mecânicas. Visto que a temperaturas superiores a 110 oC (230 oF) o cimento, após alcançar um valor máximo de resistência, inicia um processo de perda de resistência (retrogressão). Para prevenir esse efeito substitui-se parcialmente o cimento Portland por sílica com objetivo de incrementar a reação pozolânica. Esta reação modifica a trajetória do processo natural de hidratação do cimento, o gel de silicato de cálcio hidratado (C-S-H) se converte em várias outras fases com maior resistência. Polímeros também são adicionados para proporcionar maior flexibilidade e agir como barreira à propagação de trincas desenvolvidas sob tensão. O presente trabalho teve como objetivo estudar o comportamento do sistema cimento/sílica/polímero quando submetido às condições de alta temperatura e alta pressão. Foram formuladas pastas de cimento puro, pastas contendo 40 % BWOC de sílica flour e pastas com diferentes concentrações de poliuretana (5 % a 25 %) e 40 % BWOC de sílica flour. O peso específico das pastas foi fixado em 1,87 g/cm3 (15,6 lb/gal). Os resultados demonstram que as resistências da pasta contendo 40% de sílica e das com adição de polímero foram muito superiores a da pasta de cimento puro, não ocorrendo o efeito da retrogressão. As pastas com polímero apresentaram um crescente aumento da tenacidade com o aumento da concentração da mesma, sendo assim capaz de suportar as tensões. Além de se manterem estáveis termicamente acima de 180 ºC. O sistema também apresentou excelentes resultados de filtrado, reologia, água livre, estabilidade e permeabilidade. Sendo assim, o mesmo mostrou ser aplicável a poços HPHT

Health and life quality can be preserved and improved by the regular practice of physical activity. Sedentarism is an undesirable condition and represents risk for the health. This study has as objective to analyze the caloric cost and the basic physical qualities in college students of different technical levels. The research was descriptive and applied to 35 students, volunteers, from 19 to 34 years old, from both sexes, participants of the Dance Body of State University of Piauí, in the city of Teresina, in the activities of folkloric dance and walking. The caloric cost was evaluated with the accelerometer Caltrac 100/100 Plan, the basic physical qualities through the sitting and reaching test (flexibility); the vertical impulsion test, crouch (inferior members strength); the abdominal test (located muscular resistance); and the Burpee test (motor coordination). The participants were separated in two groups according to their time of practice: group 1 (beginners), group 2 (advanced). The parametric tests t by Student and correlation by Pearson were used, observing a significance p<0,05 in the sense of comparing the observed results, which showed that there are no significant differences between the two groups of students, according to the time of practice, in which concerns the caloric cost. The results of Strength, Resistance and Co-ordination test did not differ so much between the two groups. On the other hand, in the variable flexibility significant differences were observed (sig.p = 0,0022 << 0,05) between the observed groups, being Group 1 (31,5 ± 6,3) meaningfully less than Group 2 (38,1 ± 4,9), which constitutes a difference of about 21%. Such results present relations of caloric cost compensation between the studied groups, the motivation to the beginners group and flexibility to tne advanced group, justifying the lack of significant distinctions. In this sense the folkloric dance, as a physical activity, appears to be efficient, for significant co-relations are still noticed between the caloric cost levels of the dance with the walking, besides not presenting expressive differences between them.

The aim of this research was to analyse genetic markers, anthropometry and basic physical qualities in the differret stages of sexual maturation in swimmers in Paraíba. It is characterised as a descriptive cross sectional study. The sample was composed of 119 swimmers (males) that were divided among the stages of sexual maturation, from 7 to 17,9 years of age. They were associated to a local federation, the Confederação Brasileira de Desportes Aquáticos. The tests used were: genetic markers dermatoglyphics; Anthropometry body mass, stature, arm span, fat percentage and somatotype; physical qualities speed tests (25 meters crawl), strength (vertical jump) to inferior limbs, verarm throwing arremesso of a 2kg medicineball to superior limbs and abdominal), resistence (12 minutes to swimming), agility (he multistage 20-meter shuttle run test), flexibility (sit and reach test ) and coodination (stroke index); power of swimming (mean velocity in 25 meters mutiplied by body mass) and the self assessment of the sexual maturation supervised by a pediatric specialist. In the analyses we used the test normality of Shapiro-Wilk, then, we used ANOVA- one way followed by Post-Hoc test of Scheffé. The data showed in dermatogliphics a genetic tendence to velocity (L>W) with a predominance of the meso-ectomorphic somatotype profile; in relation to the physical qualities there was an evolution of the results in every stage due to the antropometric variables, except in the coordination tests. There were no significative differences between the stages. We conclude that swimming in Paraíba is composed of a signicative number of velocists with a mesomorph somatotype profile and low fat percentage, and that made it posssible to us to recomend that the trainings must be individual and according to personal characteristics of each athlete, and that the used variables must be specific for every region of the country. This dissertation presents a relation of multidiciplinar interface and its content has an application in Physical Education and Medicine

O sedentarismo é cada vez mais acentuado entre os adolescentes em todo o mundo. Objetivou-se neste estudo analisar o estado nutricional e a aptidão física de escolares norte-rio-grandenses. Participaram 2065 sujeitos, selecionados aleatoriamente (Masc = 1066, Fem = 999) (Natal n=1158; Mossoró n= 312; Lajes n= 231), divididos em três grupos etários pelos estágios maturacionais: 10 a 12 anos, 13 a 14 anos e _ 15 anos. Foi avaliada a composição corporal (IMC, dobras cutâneas tríceps e subescapular); o hábito alimentar (questionário de prevalência do consumo por grupo alimentar); o índice de atividade física (questionário Baeck) e o nível de aptidão física (testes do salto em distância, flexibilidade, resistência abdominal e cardiovascular). Utilizando-se a estatística descritiva, testes de médias pela análise dos intervalos de confiança, o teste de Kruskall-Wallis, teste t, o Qui2 e o coeficiente de contingência. Encontraram-se diferenças significativas com p < 0001 na distribuição do índice de massa corporal (n = 1701); Região Leste Potiguar (RLP) com excesso de peso e obesidade de 16,8 % e 15,2 %, a Região Oeste 16,3% e 9,6 % e a Região Central 10,4 % e 3,9 %, com as escolas privadas contribuindo significativamente na prevalência dessas variáveis nas RLP e ROP com p < 0,003 e p < 0,001 respectivamente. O hábito alimentar demonstrou que 98,3% dos sujeitos consomem alimentos do grupo das massas 98,3%; cereais 97,7%; laticínios 94,7%; frutas 92,3%; gorduras 88,3% e as hortaliças 61,6%, não havendo diferenças significativas no consumo alimentar entre o tipo de escolas e gênero (n = 300). No índice de atividade física habitual há diferenças entre esses respectivos extratos: 2,65±0,78 e 2,81±0,80 (p < 0,014) e 2,89±0,82 e 2,57±0,78 (p < 0,001), com as práticas de atividades esportivas, programas de exercícios físicos e lazer ativo mais significativo em escolas privadas 2,85 ± 1,06 e 3,37±1,26 (p < 0,001) em prol do sexo masculino com 3,47±1,24 e 2,75±1,03 (p <0,001). Resistência abdominal ( =19) e força de membros inferiores ( =128,5 cm) foram classificadas como muito fraco , a flexibilidade ( =26,9 cm) razoável e resistência geral ( =1439 m) como bom . Conclui-se que o hábito alimentar e o baixo índice de atividade física habitual influenciam negativamente os índices da aptidão física relacionada à saúde dos escolares, com menor incidência em instituições privadas em função das práticas esportivas. Este estudo apresenta relação de interface multidisciplinar, tendo o seu conteúdo uma aplicação nos campos da Medicina, Nutrição e Educação Física
