ESPIRITUALIDADE E PEDAGOGIA DO DESEJO: UM DIÁLOGO ENTRE PAULO FREIRE E RENÉ GIRARD

A exploração e a manipulação do desejo são algumas das principais marcas da cultura de consumo. Nas sociedades em que predomina essa cultura, o consumo aparece como critério de humanização, e o sentido da vida o núcleo ético-mítico em torno do qual a sociedade se organiza é a busca de acumulação de riqueza para se consumir cada vez mais. Alguns estudos têm demonstrado os aspectos sagrados dessa cultura, que se tornou uma verdadeira religião da vida cotidiana, com suas devoções, espiritualidades, mitos e ritos. Da mesma forma, alguns estudos vêm demonstrando como essa cultura determina os projetos pedagógicos. Esses estudos não são acidentais, pois religião e educação são elementos fundamentais na origem e na manutenção de qualquer cultura e sociedade humanas. Todavia, podem ser também elementos de transformação. Paulo Freire acena com o interesse pela criação de uma Pedagogia do Desejo, compreendendo que este tema é de fundamental importância na luta pela superação da exclusão social, o que infelizmente não teve tempo de formulá-la. A obra de René Girard reforça a tese de que a religião é um processo fundamental para as sociedades humanas, considerando sua real função na origem da cultura. Segundo Girard, a religião é a educadora da humanidade no processo de humanização e socialização. E sua característica mais notável é justamente a de educar o desejo, pois, devido a sua natureza mimética, constantemente é gerador de violência. Nas pesquisas sobre as relações entre Religião/Teologia e Educação, recentemente tem sido realizado o estudo dos pressupostos teológicos e espirituais das propostas educacionais. Há muitos pontos de convergência entre Paulo Freire e René Girard, alguns até complementares. O diálogo entre esses dois autores se mostra muito profícuo na discussão do tema do desejo em relação com a espiritualidade e a educação. Este trabalho é uma tentativa de buscar elementos que favoreçam a elaboração de uma Pedagogia do Desejo a partir das contribuições das Ciências da Religião.(AU)

O ESTUDANTE DA EAD (EDUCAÇÃO A DISTÂNCIA): UM ESTUDO DE PERFIL E INTERAÇÃO GERACIONAL

A aprendizagem formal e tradicional tem dado lugar a um cenário desafiador no qual educador e educando não comungam do mesmo espaço físico. A Educação a Distância (EAD), ainda é vista como uma solução que agrega cada vez mais alunos de diferentes idades que desejam uma graduação de ensino superior ou a continuidade dela. A pesquisa com o título: “O estudante da EAD (educação a distância): um estudo de perfil e interação geracional” propõe conhecer as características do perfil atual do estudante da EAD, abordando o diálogo entre as gerações no ambiente social escolar. O enfoque da pesquisa é qualitativa, exploratória e descritiva com dados que foram coletados através de entrevista com 08 alunos das gerações X e Y para assim entender se este perfil tem sido renovado com alunos mais jovens, do que a faixa etária de 25 a 45 anos. O resultado demonstra que alunos na faixa de 17 a 24 anos a cada ano aumentam 1% das matrículas. Já a faixa de 25 a 45 anos prevalece com 70% das matrículas. Portanto, este resultado revela que o perfil do aluno EAD ainda é o do jovem adulto, para adulto mais experiente, que busca a graduação com o propósito de progressão no ambiente profissional. As duas gerações citadas geração X e geração Y, mesmo em contextos históricos diferenciados de valores, crenças e comportamentos participam atualmente de uma transformação social que contempla os meios de produção do trabalho, a formação educacional e as relações sociais. O diálogo intergeracional direciona a um aprendizado compartilhado, participativo na troca de experiências mutuas. Para a geração X o jovem atual não é mais nomeado como o que precisa escutar e aprender, mas tem muito a partilhar, principalmente diante da facilidade com os meios tecnológicos. E para a geração Y, na partilha não há barreiras de idade, mas a segurança de interagir e se comunicar diante da troca de experiências

Dispositivo Médico-Cirúrgico Eletromecânico para Laparoscopia

Os avanços realizados nas técnicas cirúrgicas têm permitido que o tempo de recuperação outrora contado em dias ou até semanas tenha sido reduzido para horas, com os pacientes a saírem do hospital pelo seu próprio pé pouco tempo após a intervenção. Tal resulta numa redução do tempo de recuperação, menos desconforto para o paciente e consequente redução dos custos associados ao internamento. A redução nos tempos de recuperação é fundamentalmente devida às técnicas cirúrgicas minimamente invasivas que assentam sobretudo na utilização de instrumentos laparoscópicos. A anestesia é agora muitas vezes local ou apenas uma sedação, ficando o paciente sob efeito da anestesia durante um período menor quando comparado com as técnicas tradicionais. O desenvolvimento de dispositivos laparoscópicos que permitam ao cirurgião maior manobrabilidade associada a uma atuação simples, sem os movimentos invertidos inerentes aos instrumentos tradicionais, irão permitir realizar intervenções que outrora seriam realizadas com as técnicas tradicionais, de forma segura e menos intrusiva reduzindo o risco de complicações pós-operatórias. Os dispositivos laparoscópicos mais avançados associados a certas técnicas cirúrgicas, permitem a realização de intervenções complexas e de grande minucia através de apenas um orifício LESS (Laparoendoscopic single-site surgery), ou no caso de ser realizada com robô, R-LESS (Robotic laparoendoscopic single-site surgery); reduzindo de forma ainda mais acentuada o tempo de recuperação e o tamanho da cicatriz. O aumento da manobrabilidade dos dispositivos laparoscópicos é obtida através da inclusão de sistemas eletromecânicos relativamente complexos que tentam transpor o movimento da mão para a pinça dentro do paciente. No entanto, a adição destes sistemas podem tornar a manipulação desses dispositivos pouco intuitiva e pouco ergonómica, sobretudo se forem usados com apenas uma das mãos. Por outro lado, quando a atuação deixa de ser realizada de forma puramente mecânica e direta o cirurgião perde sensibilidade da força que está a ser exercida pelo dispositivo já que esta passa a ser efetuada através de um sistema assistido, como por exemplo motores elétricos, sistemas hidráulicos ou pneumáticos. Estes fatores resultam que a aceitação destes dispositivos pelos cirurgiões não tenha sido fácil. Para contornar este problema, o dispositivo desenvolvido para além de grande capacidade de manobra, oferece atuação natural e portabilidade. Contempla uma componente háptica de atuação hidráulica que ajudará o cirurgião a melhor perceci-onar o que se passa na ponta da pinça. Como o movimento da pinça é controlado por um sistema eletromecânico é possível escalonar a amplitude do movimento de entrada e reduzir o tremor fisiológico das mãos. A pinça e respetiva haste é convencional podendo ser usados os trocarts já existentes. Foi desenvolvido um protótipo virtual com todos os componentes necessários para um funcionamento integral. No então não foram realizados protótipos físicos de todos os componentes, nem se sabe como os diferentes módulos interagem entre si.

Uma abordagem ergonômica para análise da qualidade do pescado, desde sua captura ao seu desembarque na praia, resultante da atividade dos jangadeiros de Ponta Negra - Natal/RN

The artisan fishing activity, which involves historical - cultural, environmental, social, political, economi c, among other factors, presents, nowadays, as an important source of income, creating jobs and food, contributing to the permanence of man in their own birthplace. However, the fish, considered one of the most perishable foods, requires a proper handling and conservation, from capture to its availability in the market, in order to slow the deterioration process. Thereby, this dissertation aims to study the effect of the manipulation practices on fish quality, from capture to its landing on the beach, resul ting from fisherman’s activity from Ponta Negra - Natal/RN. It also presents the purpose of analyzing the quality of the fish and propose recommendations for their proper handling and possible solutions to add value to the product, through the improvement of the quality and good handling practices. For this purpose, the methodology used was based on ergonomic analysis of their work through observational techniques and interactional with the focus group, the jangadeiros, to understand their activity and eval uated the freshness and quality of the fish by sensory analysis, and microbiological parameters and physicochemical from existing legislation Ordinance No. 185 of May 13, 1997 and RIISPOA - amended on December 1, 2007 and RDC No. 12, dated January 2, 2001. According to the results obtained in laboratory tests, it can be established, the acceptable quality of fish as the existing rules and regulations parameters , not getting significant deterioration caused by poor handling and improper storage of fish.

Investigando a compressão da percepção de distância em ambientes virtuais através da comparação entre dispositivos de visualização

The correct distance perception is important for executing various interactive tasks such as navigation, selection and manipulation. It is known, however, that, in general, there is a significant distance perception compression in virtual environments, mainly when using Head-Mounted Displays - HMDs. This perceived distance compression may bring various problems to the applications and even affect in a negative way the utility of those applications that depends on the correct judgment of distances. The scientific community, so far, have not been able to determine the causes of the distance perception compression in virtual environments. For this reason, it was the objective of this work to investigate, through experiments with users, the influence of both the field-of-view - FoV - and the distance estimation methods on this perceived compression. For that, an experimental comparison between the my3D device and a HMD, using 32 participants, seeking to find information on the causes of the compressed perception, was executed. The results showed that the my3D has inferior capabilities when compared to the HMD, resulting in worst estimations, on average, in both the tested estimation methods. The causes of that are believed to be the incorrect stimulus of the peripheral vision of the user, the smaller FoV and the smaller immersion sense, as described by the participants of the experiment.

Uma abordagem para avaliação e tratamento de exceções propagadas no uso de serviços Web em .Net

High dependability, availability and fault-tolerance are open problems in Service-Oriented Architecture (SOA). The possibility of generating software applications by integrating services from heterogeneous domains, in a reliable way, makes worthwhile to face the challenges inherent to this paradigm. In order to ensure quality in service compositions, some research efforts propose the adoption of verification techniques to identify and correct errors. In this context, exception handling is a powerful mechanism to increase SOA quality. Several research works are concerned with mechanisms for exception propagation on web services, implemented in many languages and frameworks. However, to the extent of our knowledge, no works found evaluates these mechanisms in SOA with regard to the .NET framework. The main contribution of this paper is to evaluate and to propose exception propagation mechanisms in SOA to applications developed within the .NET framework. In this direction, this work: (i)extends a previous study, showing the need to propose a solution to the exception propagation in SOA to applications developed in .NET, and (ii) show a solution, based in model obtained from the results found in (i) and that will be applied in real cases through of faults injections and AOP techniques.

Autonomic hardware manager: uma arquitetura de hardware autonômico usando a solução de repositório ativo de componentes

This Thesis main objective is to implement a supporting architecture to Autonomic Hardware systems, capable of manage the hardware running in reconfigurable devices. The proposed architecture implements manipulation, generation and communication functionalities, using the Context Oriented Active Repository approach. The solution consists in a Hardware-Software based architecture called "Autonomic Hardware Manager (AHM)" that contains an Active Repository of Hardware Components. Using the repository the architecture will be able to manage the connected systems at run time allowing the implementation of autonomic features such as self-management, self-optimization, self-description and self-configuration. The proposed architecture also contains a meta-model that allows the representation of the Operating Context for hardware systems. This meta-model will be used as basis to the context sensing modules, that are needed in the Active Repository architecture. In order to demonstrate the proposed architecture functionalities, experiments were proposed and implemented in order to proof the Thesis hypothesis and achieved objectives. Three experiments were planned and implemented: the Hardware Reconfigurable Filter, that consists of an application that implements Digital Filters using reconfigurable hardware; the Autonomic Image Segmentation Filter, that shows the project and implementation of an image processing autonomic application; finally, the Autonomic Autopilot application that consist of an auto pilot to unmanned aerial vehicles. In this work, the applications architectures were organized in modules, according their functionalities. Some modules were implemented using HDL and synthesized in hardware. Other modules were implemented kept in software. After that, applications were integrated to the AHM to allow their adaptation to different Operating Context, making them autonomic.

Proposta de jogo químico como estratégia didática no ensino a distância abordando o conteúdo de estereoquímica

The educational games can act as a complementary tool in the teaching and learning as play an important role in the interaction of the student with knowledge, and encourage interrelationship between students and motivate them by the pursuit of knowledge. This research is intended to analyze the evidence of the students of distance education applied to semesters 2011.2 and 2012.2 for the purpose of to catalog the mistakes presented by the students, the contents of stereochemistry that attended the Chemistry of Life discipline. From the presented mistekes, develop an educational game, "walking the stereochemistry", addressing that content. The choice of stereochemistry content was due to the low number of found work in the literature, and for being one of organic chemistry content that generates learning difficulties, as it requires a mental visualization and manipulation of molecular structures, besides require observation and comparison ability by the students. The game was applied of Life Chemistry discipline of Nova Cruz Polo in semester 2013.2, with intention to verify the viability and applicability this tool for the development of motivation ability by the pursuit of knowledge by the students, as well as complement the didactical materials of the DE. Then, It was made available on the course page an opinion questionnaire to the participants of the game, as a way of to investigate the opinion their about the proposed strategy. To diagnose the contributions of the game on student learning, it was taken a comparative analysis of stereochemistry issues contained in didactic tests applied in 2013.2 semester students participating and not participating of the polo of Nova Cruz and was also compared with the tests applied at the poles of Extremoz, Currais Novos, Lajes and Caico. So the game can be considered an important resource to complement the teaching materials of distance education, because awoke the motivation for the search of knowledge and contributes to the learning of stereochemistry content.

Da voz que cala ao corpo que fala: o assédio moral no ambiente de trabalho como desafio para o serviço social

The changes ocurred in the world of capitalist labor, especially from the last decades of the 20th century, accentuated the process of manipulation and domination of the working class, materialized mainly through naturalization and / or trivialization of violence, conducted in the work environment. From this process, emerge the elements of bullying, that is, the embarrassing and humiliating practices which extend through time, degrading human race, and becoming fruitful object for study, debate and the intervention of the professionals of the Social Service area. Thus, we assume the perspective of analyzing the concepts and the work of social workers, whom work at people management area before the bullying in the workplace. We propose the following objectives: apprehend the settings of bullying, in the contemporary context of competitiveness and flexibility of work, as well as its implications for workers' health; characterize the background of this expression of violence at work in the municipality of Natal- RN; and analyze the powers and duties of the social worker in the process of prevention, identification and addressing of bullying in the context of work. This study consisted of a qualitative approach, based on the dialectical-critical method as soon as we adopt methodological procedures such as: theoretical knowledge, documental and field research, and performed using semi-structured interviews. The subjects of this research were nine (09) the Social Service professionals working in personnel management area, in five (5) institutions with legal and branches of different activities, located in Natal-RN. Even interviewed one (01) representative of the Public Ministry of Rio Grande do Norte Office (MPT-RN). The findings of this analysis indicate that bullying is a contemporary expression of "social question", which is presented as a demand for the Social-assistants – covered up and / or camuflage – under the guise of problems related to workers' health or mere conflicts of interpersonal relationships, that is, without any causal connection with the organization of work. The fear of losing job, not to be inserted in the labor market, and / or suffering reprisals, deepens the subject levels of the victims of bullying. Hence the importance of Social Workers are capable to understand the social reality, by preventing and combating the elements of bullying.

O olhar das instituições de previdência sobre a casa e a cidade: promoção, financiamento e avaliação de imóveis

The investments of Caixas and Institutos de Aposentadoria e Pensões (CAP and IAP) in homes of Natal, between the decades of 1930-60, helped to boost up the local real estate market in consolidation at the time. Inserted in the first national policy on social housing in the country, these operations have demanded the creation of a wide qualified organizational structure, which would be from the "Central Offices" of Rio de Janeiro to the decentralized units of the federal states. The professionals linked to the Local Agencies have developed, on this matter, from activities related to the design and construction of residential complexes, to the daily study of financing proposals in isolated units. As from these studies, the evaluation of shelters was essential to the effectiveness of the policy, resulting in the production of data on the market value of the properties by observing and issuing judgments upon the living quarters of different social groups. Given these considerations, the aim here is to contribute to the understanding on how to operate these real estate actions in the legitimization of boundaries about the urban space and dwellings available to workers in Natal. Therefore, the views of the city and constructions expressed by the evaluating engineers in their technical reports have been taken as the focus. Being the main primary sources of work, these reports are part of the edifices process of CAP/IAP regarding Natal, whose content is systematized in the database "Enterprises", the HCUrb Research Group. In addition, there were used local newspapers at the time and interviews with professionals as complementary sources. It was found that, in general, the evaluations have configured – in a more everyday dimension of bureaucratic routines - a vehicle, among others, circulating ideas about "home" within the social security institutions, being imbued with assumptions historically constructed about the "modern habitat". Filled in loco, the reports expose the clash between modernizing ideals in vogue and clear limitations in the city scenario at the time. Fragmented images of the town are given to read through the labels assigned to the evaluated sites – these being coated of certain "scientific" character - which both legitimated and contributed to the dynamics of appreciation/depreciation of the soil and to the socio-spatial differentiation. Contradictions were evident in the endorsement given by the technicians when financing of admittedly precarious homes for insured disadvantaged categories at the local level - such as industrial workers - while strict regulations were imposed to new construction, designed, above all, to better paid categories. By identifying raters engineers as urban agents, members of a technical-focused operating system for safety and efficiency in the real estate investments of those authorities corporatist, it is desired the usefulness of further studies on these characters, their training, professional activity and participation in the construction of discourses and practices of intervention about the city and its buildings, discussing individual and grouped interests that were left behind.

Transição demográfica e a questão educacional: uma abordagem para o ensino médio do Rio Grande do Norte

Due to demographic transition process, the educational public sector politics formers encounter a highly specific demographic situation because, nowadays, despite the demographic transition, population is still growing because of the demographic inertia; however, due to steady decline in fertility, young population tends to decrease in next years. In this way, aiming to make high school widely accessible in the country, the issue of education quality is highlighted as well the importance of the physical structure of schools and their teaching equipments to confirm a favorable or not environment for developing educational processes. In this way, this work aims to relate the enrollment of students as school types with the demand of young people who will be able to attend high school on the Rio Grande do Norte state by the year of 2020, emphasizing teaching unities structural aspects, from a school profiling to the design of three prospective alternatives. So, from INEP's Scholar Census data and IBGE population's projections, this work is composed by four stages: i) literature review about research related subjects; ii) database design and build; iii) school profiling; and, iv) prospective alternatives creation. As results, three alternatives relate potential demand and enrollment using the built profiles and they are: i) “Alternative A” attends PEE's requirements related to demands but do not provide improvements in the school structural aspects; ii) “Alternative B” points into an increase of enrollment offering to the detriment of school's structural conditions which are offered to these students; iii) “Alternative C” propitiates a quantitative enrollment increasing combined with improvements on school's physical structure. These alternatives help to support decision making related to goals and realization of universal access with physical conditions which are necessary to a favorable environment to educational activity development.

Efeito de diferentes divisões territoriais na flutuação aleatória de indicadores socioeconômicos relacionados à determinação social da saúde

This research aimed to analyse the effect of different territorial divisions in the random fluctuation of socio-economic indicators related to social determinants of health. This is an ecological study resulting from a combination of statistical methods including individuated and aggregate data analysis, using five databases derived from the database of the Brazilian demographic census 2010: overall results of the sample by weighting area. These data were grouped into the following levels: households; weighting areas; cities; Immediate Urban Associated Regions and Intermediate Urban Associated Regions. A theoretical model related to social determinants of health was used, with the dependent variable Household with death and as independent variables: Black race; Income; Childcare and school no attendance; Illiteracy; and Low schooling. The data was analysed in a model related to social determinants of health, using Poisson regression in individual basis, multilevel Poisson regression and multiple linear regression in light of the theoretical framework of the area. It was identified a greater proportion of households with deaths among those with at least one black resident, lower-income, illiterate, who do not attend or attended school or day-care and less educated. The analysis of the adjusted model showed that most adjusted prevalence ratio was related to Income, where there is a risk value of 1.33 for households with at least one resident with lower average personal income to R$ 655,00 (Brazilian current). The multilevel analysis demonstrated that there was a context effect when the variables were subjected to the effects of areas, insofar as the random effects were significant for all models and with different prevalence rates being higher in the areas with smaller dimensions - Weighting areas with coefficient of 0.035 and Cities with coefficient of 0.024. The ecological analyses have shown that the variable Income and Low schooling presented explanatory potential for the outcome on all models, having income greater power to determine the household deaths, especially in models related to Immediate Urban Associated Regions with a standardized coefficient of -0.616 and regions intermediate urban associated regions with a standardized coefficient of -0.618. It was concluded that there was a context effect on the random fluctuation of the socioeconomic indicators related to social determinants of health. This effect was explained by the characteristics of territorial divisions and individuals who live or work there. Context effects were better identified in the areas with smaller dimensions, which are more favourable to explain phenomena related to social determinants of health, especially in studies of societies marked by social inequalities. The composition effects were better identified in the Regions of Urban Articulation, shaped through mechanisms similar to the phenomenon under study.

Melhoramento genético de estirpes Saccharomyces cerevisiae YAP1-GFP e MSN2-GFP para a determinação de sensibilidade a drogas

No âmbito da saúde e farmacologia a procura de compostos para a prevenção e tratamento de doenças é constante, tendo sido valorizada atualmente a medicina tradicional aliada à existência de diversos compostos naturais provenientes de plantas, fungos e bactérias com ação anti-inflamatória e antimicrobiana. Logo é valorizada a investigação e estudos específicos das propriedades terapêuticas de compostos, dos mecanismos de ação e compreensão dos seus efeitos, úteis ao avanço da medicina. Posto isto, aliada à relevância do stresse oxidativo, associado a danos oxidativos e envolvimento em várias doenças humanas e no processo de envelhecimento, surge a necessidade de construção de uma ferramenta que permita estudar o efeito de drogas ao nível do stresse oxidativo, de modo a avaliar o potencial terapêutico, clarificar a respetiva função e abranger a aplicação de compostos que têm sido cada vez mais valorizados. Assim, foi delineado como objetivo o melhoramento genético de estripes Saccharomyces cerevisiae, de modo a promover a acumulação de drogas e, consequentemente promover as condições que despoletam a ação dos ativadores Yap1 e Msn2 ao nível do stresse oxidativo. Neste contexto, foi otimizada uma metodologia para a construção de novas estirpes haploides de S. cerevisiae com seis cruzamentos distintos que combinam a deleção independente de três transportadores diferentes (TxΔ, TyΔ e TzΔ) e, em simultâneo, cada um dos ativadores Yap1 e Msn2 em fusão com a Gfp (A-GFP). Estas estirpes haploides foram selecionadas por análises fenotípicas, confirmadas ao nível do genótipo pretendido por PCR e ensaios de microscopia de fluorescência quando sujeitas previamente ao tratamento com H2O2, que não só confirmou o genótipo A-GFP, como também permitiu avaliar qualitativamente a sensibilidade das estirpes ao H2O2 pela observação da localização nuclear da Gfp. No sentido de obter uma ferramenta simples de fácil manipulação e baixo custo que facilite a exposição de compostos e permanência no interior das células, de modo a potenciar o seu efeito a baixas concentrações e permitir uma análise mais assertiva, criou-se uma ferramenta que permitirá a caracterização de propriedades e efeitos pró-oxidantes e/ou antioxidantes de drogas ao nível do stresse oxidativo em levedura
