A configuração da educação física no Instituto Federal de Educação, Ciencia e Tecnologia do Rio Grande do Norte IFRN: contexto e perspectivas atuais.

Over time the Physical Education on IFRN has considered the sport as the only possibility of pedagogical action. In the purpose of investigating the aspects that determine this condition, this study aimed the context of physical education within the institutional framework and its current perspectives in the process of institutional transformation. In this sense, were addressed the following study questions: What political pedagogical aspects that influenced the context of Physical Education on IFRN and how the pedagogical experience on Mossoro s campus incorporated the perspectives of curricular proposals transformation for the High School and the theoretical changes of the Brazilian Physical Education. Methodologically the work was based on a qualitative approach characterized as a descriptive- comparative research. The technique of discourse analysis was employed in the speech of research collaborators having as categories of analysis the professional activities time in the institution; The ratio of official use of the assumptions to the pedagogical practice of Physical Education in IFRN; The sport in the education process of students and The Prospects of Physical Education in the current configuration of IFRN. The data analysis allowed us to infer that the theoretical methodology of pedagogical practice of Physical Education in IFRN need to be reformulated and that it is necessary a contextualization with the curricular principles of the political institutional pedagogical project and with the Curriculum Guidelines for Secondary Education. The teaching experience developed in the Mossoro s Campus was contextualized with the national curriculum guidelines for secondary education and the theoretical changes of the Brazilian Physical Education. We conclude that it is necessary a collective action of the group of teachers to transform the educational profile of Physical Education of IFRN, beyond the institutional support to be able to consolidate the physical education curriculum component in the current dimensions of society, human being, education, science, technology and work, proposed by the philosophical principles and epistemological political project of IFRN educational

O sensível no trabalho docente: representação social entre docentes do Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte

The aim of this study was to analyze the social representation of the sensible among teachers of the Federal Institute of Education, Science and Technology of Rio Grande do Norte, attempting to identify its constituents and understand the dynamics that gives functionality to your organization. The study is significant considering that the professional conduct can not be delineated in its complexity without unraveling the social representations that teachers themselves have of their being and doing professional. The theoretical and methodological framework of the research is the theory of social representation. 107 teachers from various backgrounds participated. To collect the data were used as instruments : a questionnaire listing, which subsidizes the characterization of the subjects , the TALP - technique of free association of words ( ABRIC , 1994) , the PCM - Procedure for Multiple Ratings ( ROAZZI , 1995) ; questionnaire redemption of sensitive memories of the subjects in their school experiences of childhood , adolescence, youth and teaching practice . The PCM data, in which the slogan was directed at rating Give class, were submitted to multidimensional statistical analysis. Already TALP was analyzed by EVOC 2000 software, the profile questionnaire received descriptive statistical analysis and the memories received the questionnaire analysis of thematic content, Bardin (2004). Taken together, the results point to a social representation of sensitive teaching (the game, the fun, the touch, the smile, the relaxation) are not in the classroom. The sensitive pure still fits in school, but only in the courtyard, on the playground, in the intervals, therefore, outside of space-time class, playful perch that lives in each of us is totally strange to this world of the classroom . After doing the Approximation of ideas , we realized three discourses evident in the reports of teachers : the discourse of Numbness in which we perceive the distance of the teacher in relation to sensitive component as a facilitator in the learning process , the discourse of Feeling , in which we can discern small approximation to the sensitive dialogues and proposed in this study , the speech of reflection in which teachers analyze, evaluate and establish a discourse on the importance of education in sensitive , but not actualize in their teaching practice

Automedicação e guarda de medicamentos por universitários das áreas de saúde e tecnologia

This study aimed to compare self-medication and domestic drug storage among undergraduate students in the areas of health and technology. This is a descriptive study of cross-sectional type and quantitative approach, conducted in a Public University of Natal, Rio Grande do Norte, Brazil. The sample consisted of 300 students of the third year of undergraduate courses at the Center for Health Sciences and Technology Center, selected through a simple random sample. The project was authorized by the Ethics Committee of Federal University of Rio Grande do Norte (CAAE 0137.0.051.000-10). Data collection lasted twelve months and was conducted during the period of study participants, in the university environment. The instrument for data collection was a structured questionnaire consisting of open and closed questions. For data analysis, we used descriptive statistics and applied Fisher s exact test and Chi-square test with adopted level of significance α=5% and 10%. For the variables that correlated with self-medication (p<0.05), we subsequently calculated the odds ratios and confidence intervals. The prevalence of undergraduate students who performed self-medication in the 15 days prior to the collection accounted for 33.7% and, by analyzing each knowledge area, we verified was a higher prevalence of self-medication among students in the technological area (37.3%). The analysis of the socio-demographic characteristics of the participants in this practice revealed a significant difference between the knowledge areas in the income and self-medication variables (p=0.005). General analgesics and antipyretics (N02) represent the therapy group most used in self-medication (57.4%), especially acetaminophen (28.7%), and the main health situations that motivated this practice related to pain, especially headaches (48.5%). Regarding the indication of the drugs used, the majority of students self-medicated themselves on their own (71.3%). As regards to the in-home drug storage, most of the participants had a home pharmacy (88%). By analyzing the socioeconomic characteristics, the variables medical service and home medicine presented a significant difference (p=0.002). General 10 analgesics and antipyretics constituted the medicinal products most found in the home pharmacies, especially acetaminophen. The main room used for the drug storage was the kitchen (36.4%), most students kept these products in boxes of different materials (38.6%) and the medicines stored at home of most of the participants were not easily accessible to children (75%). The results reinforce the need to develop strategies, from the reality found, aiming to encourage and implement educational and preventive activities with undergraduate students on the importance of proper self-medication and in-home drug storage. Despite the sample in our study is relatively small, not representative for the whole country, we believe that, at national level, the panorama of the subject does not present major differences

Uma perspectiva de extensão do modelo de aceitação de tecnologia para explicar o uso de linguagens de desenvolvimento WEB: pesquisa com desenvolvedores Pyton e Java

The spread of the Web boosted the dissemination of Information Systems (IS) based on the Web. In order to support the implementation of these systems, several technologies came up or evolved with this purpose, namely the programming languages. The Technology Acceptance Model TAM (Davis, 1986) was conceived aiming to evaluate the acceptance/use of information technologies by their users. A lot of studies and many applications have used the TAM, however, in the literature it was not found a mention of the use of such model related to the use of programming languages. This study aims to investigate which factors influence the use of programming languages on the development of Web systems by their developers, applying an extension of the TAM, proposed in this work. To do so, a research was done with Web developers in two Yahoo groups: java-br and python-brasil, where 26 Java questionnaires and 39 Python questionnaires were fully answered. The questionnaire had general questions and questions which measured intrinsic and extrinsic factors of the programming languages, the perceived usefulness, the perceived ease of use, the attitude toward the using and the programming language use. Most of the respondents were men, graduate, between 20 and 30 years old, working in the southeast and south regions. The research was descriptive in the sense of its objectives. Statistical tools, descriptive statistics, main components and linear regression analysis were used for the data analysis. The foremost research results were: Java and Python have machine independence, extensibility, generality and reliability; Java and Python are more used by corporations and international organizations than supported by the government or educational institutions; there are more Java programmers than Python programmers; the perceived usefulness is influenced by the perceived ease of use; the generality and the extensibility are intrinsic factors of programming languages which influence the perceived ease of use; the perceived ease of use influences the attitude toward the using of the programming language

Fonte de energia alternativa: um estudo sobre a percepção ambiental, social e econômica do biodiesel com docentes do Centro de Tecnologia do gás da cidade de Natal RN

Meaning fuel and renewal energy source s derivative additives, the term biodiesel exists in Brazil since 1980, when it was signed its first patent by Expedito Parente. Since then, its importance has grown gradually due to the worsening of the ambient problems, since its use has became a highly promising alternative to the pollution decrease, as in the carbon dioxide issue as with the smoke and sulfur oxide. In Brazil, it was created the National Program of Production, whose objective is to insert the new product in the country s energy matrix, strengthening the economy and creating new employment opportunities, being an important product to the national energetic independence, since Brazil still imports diesel to its domestic consumption. This study aims to identify the ambient, social and economic perception of the teachers from the Technology Center of Natal city (CTGÁS-RN) to the biodiesel. For that, it was used a questionnaire closed questions, organized in the likart scale, directed to the tree spheres of the research analysis, the biodiesel and its social, ambient and economic nuances, totaling 31 questionnaires full answered. In its objectives, the research was descriptive and in its approach it was qualitative. To the data analysis it was used statistical tools (Statistic software, 6.1 version and Microsoft Excel 2003). The research revealed the predominance of the ambient aspect in the sight of the teachers, followed by the social ones. The economic factors represent a minor percentage in the analysis when compared to other

Fatores influenciadores da implementação de ações de gestão de segurança da informação :um estudo com executivos e gerentes de tecnologia da informação das empresas do Rio Grande do Norte

Information is one of the most valuable organization s assets, mainly on a global and highly competitive world. On this scenery there are two antagonists forces: on one side, organizations struggle for keeping protected its information, specially those considered as strategic, on the other side, the invaders, leaded by innumerous reasons - such as hobby, challenge or one single protest with the intention of capturing and corrupting the information of other organizations. This thesis presents the descriptive results of one research that had as its main objective to identify which variables influence the Executives´ and CIOs´ perceptions toward Information Security. In addition, the research also identified the profile of Rio Grande do Norte s organizations and its Executives/CIOs concerning Information Security, computed the level of agreement of the respondents according to NBR ISO/IEC 17799 (Information technology Code of practice for information security management) on its dimension Access Control. The research was based on a model, which took into account the following variables: origin of the organization s capital, sector of production, number of PCs networked, number of employees with rights to network, number of attacks suffered by the organizations, respondent´s positions, education level, literacy on Information Technology and specific training on network. In the goal´s point of view, the research was classified as exploratory and descriptive, and, in relation of the approach, quantitative. One questionnaire was applied on 33 Executives and CIOs of the 50 Rio Grande do Norte s organizations that collected the highest taxes of ICMS - Imposto sobre Circulação de Mercadorias on 2000. After the data collecting, cluster analysis and chi-square statistical tools were used for data analysis. The research made clear that the Executives and CIOs of Rio Grande do Norte s organizations have low level of agreement concerning the rules of the NBR ISO/IEC 17799. It also made evident that the Executives and CIOs have its perception toward Information Security influenced by the number of PCs networked and by the number of attacks suffered by the organizations

Terceirização em tecnologia da informação sob os aspectos de estratégia, tomada de decisão e análise de investimentos :estudo de múltiplos casos em três organizações franqueadas da Coca-Cola do Brasil

Desde a criação da tecnologia e do seu uso pelas empresas, a relação custo e benefício nem sempre foi bem elucidada tanto para os responsáveis pela área de tecnologia quanto para a alta direção. Mas, apesar disto, cada vez mais as organizações investem maciçamente em tecnologia, esperando que esta seja a solução para diversos problemas. Por isto, esta questão tem se tornado crucial para o processo de tomada de decisões, visto que investimentos nesta área costumam ser dispendiosos e, na atual conjuntura, estas análises precisam ser extremamente criteriosas para que se miniminizem as possibilidades de insucesso dos projetos, principalmente numa economia estabilizada e de concorrência acirrada. Uma das alternativas que as empresas têm buscado para atingir o sucesso e correr menos riscos é a terceirização da área de TI. Partindo desta visão, a presente dissertação tem por objetivo realizar uma investigação sobre a terceirização dos serviços de TI em todos os seus aspectos, isto é, desde a sua motivação, serviços efetivamente terceirizados, vantagens, desvantagens e possíveis obstáculos, a visão do alinhamento estratégico da TI, os processos de gestão de contratos e formas de controle e, por fim, tendências futuras. Trata-se de uma pesquisa de múltiplos casos, envolvendo franquias do Sistema Coca-Cola no Brasil. O estudo apresenta uma pesquisa bibliográfica sobre o processo de tomada de decisão empresarial, a análise de investimentos, a gestão e a terceirização da TI, o que permitem definir as dimensões de análise da pesquisa. Na pesquisa de campo foram entrevistados os gerentes da área de TI, nas cidades de Brasília-DF, Goiânia-GO e Ribeirão Preto-SP. A pesquisa de campo permitiu identificar como as mesmas avaliam seus investimentos em TI, como esta área é gerenciada, o que as levou a optar pela terceirização e como os processos terceirizados afetam a organização. Por se tratar de uma pesquisa qualitativa, optou-se por analisar comparativamente as três organizações. Com a realização deste estudo, obtiveram-se, como principais resultados, que as organizações estão utilizando a terceirização em TI para focar no negócio principal e, mesmo encontrando diversas desvantagens, inclusive com relação a custos, acreditam que os benefícios justificam. Ainda identificaram-se alguns obstáculos internos para a terceirização, principalmente quanto ao receio de se perder a inteligência do negócio. O acompanhamento dessas atividades terceirizadas é realizado pela equipe interna e por critérios estruturados, onde se verificam os níveis de serviço

Proposta de uma máquina para colheita mecanizada de babaçu (Orbignya phalerata Mart.) para a agricultura familiar

O babaçu é uma planta de importância capital na economia de subsistência do norte do Brasil. Sua configuração sócio-ambiental o torna destaque na situação regional amazônica, onde os produtos advindos do babaçu possibilitam renda para a camada mais pobre da população amazônica, além da questão ambiental que é conotada à preservação dos babaçuais naturais. Um dos gargalos técnicos da produção do babaçu, em especial visando a extração do óleo de babaçu, é a colheita feita de forma manual e no sistema extrativista. O objetivo deste trabalho é propor o conceito de uma colhedora de babaçu moto-mecanizada, capaz de trabalhar em cultivos artificiais, assim como em florestas naturais. Foi utilizada a metodologia de projeto da matriz morfológica, onde foram elencadas as possíveis combinações de mecanismos e elementos para uma colhedora de babaçu. Como resultado foi obtido um conceito teórico, sendo concluída a viabilidade técnica de tal projeto, em estudos futuros pretende-se desenvolver estudos de viabilidade técnica detalhados, assim como estudos de viabilidade econômica.

Desenvolvimento e projeto de colhedora de babaçu (Orbignya phalerata Mart.) para agricultura familiar nas regiões de matas de transição da Amazônia

O babaçu (Orbignya phalerata) é uma típica palmeira das matas de transição dos ecossistemas Amazônia/Cerrado e Amazônia/Caatinga, sendo de grande importância econômica, social e ambiental nestas regiões. Os produtos advindos dos babaçuais possibilitam renda para uma das camadas mais pobres da região amazônica e um dos entraves para a obtenção eficiente destes produtos é a colheita dos cocos de babaçu, que atualmente se faz no sistema extrativista. O objetivo deste trabalho foi realizar o desenvolvimento e projeto de uma colhedora de babaçu adaptável ao ambiente de trabalho da agricultura familiar e as características das matas de transição amazônicas. Para tal foram realizados estudos de literatura que nortearam as decisões e simplificações de projeto, assim como foram realizados os cálculos e desenhos da nova colhedora. O projeto foi realizado através de ferramentas de engenharia que apresentaram como resultados o memorial de cálculo que descreve o caminho técnico para o dimensionamento dos elementos constituintes da colhedora e a partir destes os desenhos detalhados dos elementos da nova máquina. Pelos desenhos detalhados suas considerações e decisões concluí-se que a colhedora de babaçu apresenta-se passível de ser construída com materiais nacionais de baixo custo, além de fácil operação, manutenção e com mínimo efeito sobre os babaçuais naturais.

Qualidades físicas e químicas do abacaxi comercializado na CEAGESP São Paulo

O presente trabalho buscou conhecer a variação das características físicas e químicas do abacaxi comercializado no Entreposto Terminal de São Paulo (ETSP), da Companhia de Entrepostos e Armazéns Gerais de São Paulo (CEAGESP), no período de setembro de 2005 a março de 2006. As avaliações foram realizadas na CEAGESP e nos laboratórios do Departamento de Agroindústria, Alimentos e Nutrição da Escola Superior de Agricultura Luiz de Queiroz - ESALQ/USP. Foram realizadas coletas em intervalos de duas semanas, em três atacadistas, com as amostras recolhidas de forma aleatória, padronizadas em frutos tipo 10 (caixa contendo 10 frutos), compostas de dez frutos por atacadista/origem. As amostras foram coletadas nos lotes oferecidos para comercialização pelos atacadistas. Foram avaliadas as seguintes características físicas e químicas: peso do fruto inteiro, peso da coroa, avaliação visual da coloração da casca, densidade, coloração da polpa, pH, teor de sólidos solúveis (SS), acidez titulável (AT), além da relação SS/AT. Para a análise estatística, foi utilizado o Programa SAS. Pelos resultados, observou-se que, dentre as regiões produtoras de abacaxi, destacaram-se, com relação à regularidade de oferta para os três atacadistas, os pólos de Canápolis ('Smooth Cayenne'), Sapé e Miracema do Tocantins ('Pérola'). As diferentes regiões produtoras de abacaxi 'Pérola' apresentaram uma grande variação em relação ao peso médio dos frutos comercializados, indicando diferenças na tecnologia de produção adotada. Dentre as regiões produtoras de abacaxi, houve variação estatística no teor de sólidos solúveis ao longo do período analisado nos pólos de Canápolis ('Smooth Cayenne') e Itaberaba, Sapé e Miracema do Tocantins ('Pérola'). Dentre os parâmetros químicos analisados, a determinação do teor de sólidos solúveis por amostragem com uso do refratômetro manual, associado à maturação aparente (cor da casca), pode representar um avanço significativo na indicação da qualidade dos frutos comercializados, o que permite concluir ser desnecessário o uso de etefon na fase de pré-colheita.
