Este trabalho visa investigar os saberes manifestados pelos alunos do curso de Matemática na Universidade Federal do Pará (UFPA), em relação à utilização da informática em sua formação. Para atender esse objetivo, utilizamos uma metodologia referente ao estudo de caso. Fizemos um breve histórico sobre a informática educativa no Brasil, destacamos os avanços e pesquisas na área e abordamos as principais maneiras de utilizá-los na educação; tratamos dos aspectos relacionados à Educação Matemática com alguns softwares educativos e as experiências com o uso do computador; e, em seguida, passamos para a nossa investigação, fundamentada nos documentos escritos pelos alunos e professores do curso de Licenciatura em Matemática da UFPA. As informações foram obtidas por meio de questionários aplicados aos alunos, durante o segundo semestre letivo de 2004, e aos professores no primeiro semestre letivo de 2005. Pudemos observar, nas análises, que alunos e professores consideram muito importante a inserção da informática ao currículo da Licenciatura em Matemática, porém destacam que este ensino ainda não ocorre e há necessidade de que ele faça parte efetiva da formação dos professores de Matemática, pois, pode contribuir para a melhoria do processo de ensino aprendizagem e é uma ferramenta indispensável para a educação.

Uma série de iniciativas para melhoria do processo de software surgiu recentemente visando melhorar a qualidade e a produtividade em organizações de desenvolvimento de software. Alguns modelos e normas têm buscado a implantação de melhorias no processo de desenvolvimento de software, o MPS.BR é um deles. Esse modelo de melhoria de processo é voltado para as micro, pequenas e médias empresas, de forma a atender as suas necessidades de negócio e foi o modelo escolhido para ser explorado nesse trabalho. Várias são as vantagens adquiridas com a implantação de um modelo de melhoria, umas delas é a definição de um processo sistemático de desenvolvimento de software, que auxilie tanto na qualidade e produtividade do processo quanto na qualidade do produto desenvolvido. Com um modelo de processo definido a organização pode contar com diversos benefícios associados à padronização, como, por exemplo, a otimização, a redução de custos com retrabalho, a redução de defeitos nos produtos, dentre outros. Mas não existem modelos prontos que possam ser aplicados diretamente a uma empresa específica de desenvolvimento de software e, por isso, é necessário modelar o processo, customizando-o, com o objetivo final de gerar um modelo que adequadamente represente o processo da organização. Uma das dificuldades para a implantação de modelos como o MPS.BR é a falta de metodologia que mostre como a implantação de melhoria deve ser feita e não apenas o que deve ser feito. Este trabalho propõe uma metodologia para a implementação do modelo MPS.BR baseada no modelo de implantação IDEAL, através de uma ferramenta específica, chamada WebAPSEE. A metodologia foi experimentada no CTIC - Centro de Tecnologia da Informação e Comunicação da UFPA que ao final do trabalho foi avaliado Nível G do MPS.BR.

Increasingly, the furniture market is competitive. The construction industry presents itself in growth, mainly due to the lines of existing incentives and tax credits established by the government, assisting the impulse to purchase real estate, building materials and furniture. Factors that promote and strengthen the sector's growth. With high demand from the furniture market, demand for higher quality and increasing technological advances, research is often undertaken in search of solutions for process improvement and product features, focusing on the production of materials less harmful to the environment, provision of raw press to lower cost, improve the production process and product development of cost-effective. This research focuses on the comparative study between two materials widely used in furniture manufacturing. MDF (Medium Density Fiberboard) and MDP (Medium Density Particleboard). The subject provides the focus in furniture production, presenting and comparing data collected from three companies producing panels between physical and mechanical characteristics of the materials, also presenting some of the main factors of influence on the quality of the panels, their features and applications on mobile. The study shows the high potential of using the MDP (Medium Density Particleboard) in furniture designs, as well as MDF (Medium Density Particleboard), favoring the final terms of the project , resulting in better utilization of each material , avoiding waste and increase unnecessary cost . Currently, several projects are developed in MDP and MDF furniture, where there is no relevance to their characteristics regarding their limitations. Many of these furnishings are designed without a specific study of the best use and positioning of each material, with better utilization , favoring collateral design , especially furniture designed exclusively for each environment . The lack of technical ...

In an industry, being a big one or small one, the process improvement is always a focus for it to increase in the market. The improvement, if searched in a simple meaning, brings the unique meaning of change to better. However the meaning of process improvement can take much more than a superficial point of view. Kaizen, Process improvement, Continuous improvement, they are some denotations much more comprehensive of a such a term carried of so many meanings. A good concept of improvement if to search inside processes a more appropriate way, a more succinct, a more economic way to realize it. The idea is to make the process in a better way. In this graduation thesis, there will be presented a process improvement realized in a Vale do Paraíba company. For that, it was used the DMAIC to obtain, measure and control the process improvement. It should be noted that the goal is to present and discuss a process improvement

Therebar of aluminum 1350 AA produced by CBA are used inthe manufacture of wires and cables for electric power transmission, which marketshows increasingly favorableto aluminum due to itslow densityand high electrical conductivity, but to ensure that this materialmeets all specifications of projectsfor electricity transmission, it must have homogeneity in the chemicaland mechanicalproperties.One of the points of improvement in the process of rod production isreducing the high variation of the limitof tensile strengthalong the coils, therefore, this work seeks a better understanding of the factors that significantly influence the mechanical properties of rebar, specifically assessing the influence oftemperatureat the output of the coils, which can cause a recovery effect on the material andif thereare relevantdifferences between the two modes of rebar production: auto and manual.Samples of six coils have been specifically produced forthis study, which weresubsequently subjected to different annealing temperatures for one hour and ten minutes, similar to what occurs in the output of the coil from the machine. The tensile tests showed that aluminum 1350 AA is significantly influenced by temperature, whose behavior was very similar to that presented in the literature. It was found that the phenomenon of recovery occurred more significantly at high temperatures. Through the optical electron microscope Zeiss, 18 surface maps were made with 100x magnification for each sample in different conditions and the images were analyzed using entropy and fractal dimension, aiming to relate the condition of surface hardening on mechanical property of the samples in that condition. The results showed that these methods can be applied, provided they do not have any kind of imperfection on the surface, once they can influence the results. The study concluded that a more efficient cooling is required in ... (Complete abstract click electronic access below)
