From this perspective, this study was to investigate the contribution of constructivist methodology in teaching Production Engineering. For this purpose an experiment was conducted in groups of students of Engineering Production UFERSA, UFF e CEFET-RJ, with the aim of comparing the gains made by students in a traditional classroom and in a constructivist classroom. The two classes discussed the concepts related to Just In Time philosophy. For the constructivist classroom was used Game Production Management, activity games adapted for use in the teaching of production engineering, raised in the literature. Comparison of the results was performed from the application of statistical tests and McNemar Binomial. The results obtained by use of statistical tests denote the contribution of the inclusion of activities in teaching Constructivist Production Engineering. The results collected through a questionnaire administered to students who participated in the experiments showed the acceptance of constructive activity as a tool to complement the exhibition of traditional concepts covered in class. / O método de ensino construtivista tem como característica principal a adoção de atividades práticas em que o individuo interage diretamente com o objeto de seu desenvolvimento, sendo motivado a participar ativamente do processo de aprendizagem em que está incluído, explorando seus conhecimentos anteriores e sua criatividade. Sob essa perspectiva, este trabalho buscou investigar a contribuição da metodologia construtivista no ensino de Engenharia de Produção. Para isso foi realizado um experimento em turmas de alunos dos cursos de Engenharia de Produção da UFERSA, UFF e CEFET-RJ, com o objetivo de comparar os ganhos obtidos pelos alunos em uma aula tradicional e em uma aula construtivista. As duas aulas abordaram os conceitos relacionados à filosofia Just In Time. Para a aula construtivista foi utilizado o Jogo Gestão da Produção, atividade adaptada de jogos utilizados no ensino de engenharia de produção, levantados na literatura. A comparação dos resultados obtidos foi feita a partir da aplicação dos testes estatísticos de McNemar e Binomial. Os resultados obtidos pela utilização dos testes estatísticos denotam a contribuição da inserção de atividades construtivistas no ensino de Engenharia de Produção. Os resultados coletados por meio de um questionário aplicado com os alunos que participaram dos experimentos mostrou a aceitação da atividade construtivista como instrumento complementar a exposição dos conceitos abordados nas aulas tradicionais.

The periodization of work is comprised from 1953 to 1961, as it is the time period in which the Foundation of the City of Rio Grande was created, the unit responsible for supporting the School of Industrial Engineering until mid-1960s, when the school was federalized, process which begins in 1961. In order to analyze the history of this teaching institution, there had to be a reconstruction of its early years, having as main source of information, the school culture preserved in its materiality in a variety of collections in the city of Rio Grande. In addition to the material sources, they were also conducted interviews with faculty members and students of early years of the School of Industrial Engineering, considering memory as a major source of documentation for this research. From the traces of this school culture, it was possible to recollect their first steps, addressing their spaces, professors, subjects, among many other aspects. It is worth noting the presence of some important characters in the history of the institution, emphasizing the figure of Eng. Francisco Martins Bastos, a key person, for the school could finally become a reality and launch the history of higher education in Rio Grande. His entrepreneurial nature along with his role as manager backed by the interest and investment from a group of individuals belonging to a highly educated social class and professionally stabilized, were all crucial to the emergence of this institution. / A presente dissertação tem como objetivo mostrar como se deu o surgimento da Escola de Engenharia Industrial (EEI), primeira instituição de ensino superior da cidade do Rio Grande, na década de 1950. A periodização do trabalho está delimitada de 1953 a 1961, por tratar do período em que é criada a Fundação Cidade do Rio Grande, entidade mantenedora da EEI até meados da década de 1960, quando a escola é federalizada, processo que inicia em 1961. Para poder analisar a história desta instituição de ensino foi preciso reconstruir os seus anos iniciais, tendo como principal suporte, a cultura escolar preservada em sua materialidade nos diferentes acervos na cidade do Rio Grande. Além das fontes materiais, também foram realizadas entrevistas com membros do corpo docente e discente dos primeiros anos da EEI, considerando a memória como uma importante fonte documental para esta pesquisa. A partir dos vestígios desta cultura escolar, foi possível rememorar seus primeiros passos, abordando seus espaços, professores, alunos, disciplinas, dentre tantos outros aspectos. É válido destacar a presença de alguns personagens importantes na trajetória da EEI, dando ênfase à figura do Engº Francisco Martins Bastos, personagem chave para que a escola pudesse enfim, se tornar uma realidade e dar início à história do ensino superior da cidade do Rio Grande. Sua perspicácia empreendedora atrelada ao seu papel de gestor, respaldado pelo interesse e investimento de um grupo de indivíduos pertencentes a uma classe social escolarizada e estabilizada profissionalmente, foram cruciais para o surgimento desta instituição.

This Master Thesis is the research done in the country of Rwanda. The project leads to study the climate of this country in order to establish whether this climate could be used to produce energy from air and to implement the first wind turbine for serving the nation.   After an introduction about the historical background of wind power, the thesis work deals with assessment of wind energy potential of Rwanda in focusing of the most suitable place for wind power plants. The best location with annual mean wind speed, the rate of use of turbine with hub height for an annual production per year, the mean wind speeds for 6 sites of Rwanda based on ECMWF for climatic data for one year at relief of altitude of 100m and coordinates are reported too.   The result of energy produced and calculations were done based on power hitting wind turbine generator in order to calculate Kinetic energy and power available at the best location to the measurement over the period of 12 months, that could be hoped for long term.   With help of logarithmic law, where wind speed usually increases with increasing in elevation and the desired wind speeds at all 6 sites were used. The annual energy production was taken into account at the best site with desired wind speed at the initial cost of turbine as well as the cost of energy (COE).However, with comparison of the tariff of EWSA, the price of Wind designed in this Research per kWh is cheaper and suitable for people of Rwanda. / <p><em>Rwanda has considerable opportunities development energy from hydro sources, methane gas, solar and peat deposits. Most of these energy sources have not been fully exploited, such as solar, wind and geothermal. As such wood is still being the major source of energy for 94 per cent of the population and imported petroleum products consume more than 40 per cent of foreign exchange. Energy is a key component of the Rwandan economy. It is thus recognized that the current inadequate and expensive energy supply constitutes a limiting factor to sustainable development. Rwanda’s Vision 2020 emphasizes the need for economic growth, private investment and economic transformation supported by a reliable and affordable energy supply as a key factor for the development process. To achieve this transformation, the country will need to increase energy production and diversify into alternative energy sources. Rwandan nations don’t have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural areas. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The application of renewable energy technology has the potential to alleviate many of the problems that face the people of Rwanda every day, especially if done so in a sustainable manner that prioritizes human rights.</em></p>
