No. of bitstreams: 1 luizcarlosdeoliveira.pdf: 1328502 bytes, checksum: b6d2354ca717b29dbe99fb98d6ef8569 (MD5) Previous issue date: 2013-10-25 / A partir do ano de 2008, a Escola Municipal Antônio Carlos Fagundes, situada em Juiz de Fora, MG, implantou um novo tipo de Laboratório de Aprendizagem para os anos iniciais do ensino fundamental. O projeto é diferente dos demais praticados na rede municipal, pois, não apresenta a mesma metodologia de ensino praticada nos Laboratórios de Aprendizagem, os alunos são enturmados de acordo com suas dificuldades de aprendizado e possuem duas professoras: uma regente para o horário normal de aula e outra para o contra turno, mas que também participa junto com a professora regente no horário regular de aula. O objetivo dessa dissertação é avaliar o projeto e identificar os benefícios e entraves pedagógicos com intuito de propor ajustes e mudanças para maximização dos resultados. Esse trabalho de pesquisa iniciou com o estudo comparativo da proposta da Secretaria de Educação de Juiz de Fora para o Laboratório de Aprendizagem e os moldes implementados pela escola. Foi aplicado um questionário aos professores, coordenadores e gestores para verificar a percepção dos docentes em relação ao projeto. Os índices de retenção e das avaliações externas da escola foram utilizados para ampliar as análises, dos resultados antes e depois da implantação do projeto. As propostas de enturmação por dificuldade de aprendizagem e a presença simultânea de duas professoras regentes em uma mesma sala também foram pontos de análises e reflexões. Por fim, esse estudo identificou e subsidiou alguns elementos de gestão necessários para a articulação do Laboratório de Aprendizagem da Escola Municipal Antônio Carlos Fagundes frente à Secretaria de Educação e à própria escola. / From 2008 on, has been implemented at Municipal School Antônio Carlos Fagundes, located in Juiz de Fora, MG, a new kind of Learning Laboratory for the early years of elementary school. This project is different from all the others practised in the municipal network as it does not perform the same teaching methodology practised in previous Learning Laboratories: students are grouped in classes according to their learning difficulties and they have two teachers - one who is conductor during regular class time and another who works during the turn against, but also participates along with the regent teacher at regular class time. The objective of this dissertation is to evaluate the project and identify the benefits and barriers to educational goals and to propose adjustments and changes in order to maximize results. This work of research began with a comparative study of the proposal of the Department of Education of Juiz de Fora for the learning lab and the molds implemented by the school. A questionnaire has been applied to teachers, coordinators and managers to verify the perception of the formers in relation to the project. The rates of retention and external evaluations of the school were used to expand the analyses of the results before and after the implementation of the project. The proposals of grouping the classes by learning difficulties and the simultaneous presence of two regent teachers in a single room were also points of analyses and reflections. Finally, this study identified and subsidized some management elements necessary for the articulation of the Learning Laboratory of Municipal School Antônio Carlos Fagundes in the face of Department of Education and the school itself.

Cursos laboratoriais possuem grande importância científica para a educação em geral, a atual modernidade com ideias inovadoras e toda tecnologia oferecida está transformando cada vez mais os laboratórios, nos levando a uma evolução significativa tanto na parte acadêmica quanto na aprendizagem dos estudantes. A preocupação quanto a conservação de peças anatômicas existe a mais de 5 mil anos, pois o uso de peças cadavéricas naturais são indispensáveis para o ensino, devido a contribuição no aprendizado prático melhorando as habilidades aplicativas, assimilativas e compreensivas da disciplina. O presente trabalho propõe a utilização de automatização em laboratórios de anatomia, com todo planejamento necessário quanto a descarte de substâncias, exaustão e ventilação adequada, monitores acima das bancadas com atlas virtuais e acesso a internet, roldanas para transporte de animais de grande porte e o uso de técnicas anatômicas alternativas visando abolir o uso do formol como conservante das peças de estudo, fornecendo um ambiente mais agradável facilitando no aprendizado dos estudantes e no trabalho dos funcionários. Para a execução das técnicas anatômicas foram utilizados cães e gatos provenientes de clinicas veterinárias, cujo ao entrarem em óbito foram doados por seus respectivos donos ao assinarem o termo de doação redigido sendo totalizado um gato e quatro cães. Também foram utilizados antigos órgãos do laboratório de anatomia animal do Departamento de Ciências Básicas da FZEA/USP localizada em Pirassununga que não possuíam mais função em aulas prática, sendo cedidas pelo chefe do departamento através de um termo assinado pelo mesmo, sendo essas peças especificamente: uma língua, um rim, um coração e um encéfalo de bovino, dois estômagos, um rim e um baço de equino e um estômago de suíno. As quatro técnicas anatômicas defendidas nesse trabalho mostraram ser suficientes para atender as necessidades dos estudantes quanto o estudo da anatomia, devido à perfeita evidenciação de estruturas externas e internas dos animais. O plano laboratorial foi executado com a ajuda dos programas AutoCAD e SketchUP, cujo possibilitam a elaboração de desenho técnico em duas dimensões (2D) e criação de modelos tridimensionais (3D). / Laboratory courses have great scientific importance to education, the current modernity with innovative ideas and technology offered whole is becoming more and more laboratories, leading us to a significant development in the academic and in student learning. The concern about the anatomical specimens preservation exist for over 5000 years, because the natural corpse pieces are indispensable for teaching that contribute in improving learning practical skills applicative, assimilative and understanding of the discipline. This paper proposes the use of automation in anatomy laboratories, with all necessary planning regarding disposal of substances, and exhaust ventilation, monitors above the countertops with virtual atlas and internet access, pulleys to transport large animals and use of alternatives anatomical techniques to abolish the formaldehyde as a preservative parts of study, providing a more pleasant environment in facilitating student learning and the work of the employees. For the execution of anatomical techniques were used dogs and cats from veterinary clinics, which they entered in death were donated by their owners to signing the donation being drafted totaled four dogs and one cat. We also used some old organs of animal anatomy lab of the Department of Basic Sciences FZEA / USP located in Pirassununga who had no role in more practical lessons, being provided by the department head via a signed for the same term, and these pieces specifically: a tongue, kidney, heart and brain of veal, two stomachs, one kidney and a spleen of horse and a pig stomach. The four anatomical techniques advocated in this work proved to be sufficient to meet the needs of students and the study of anatomy, showing a perfect disclosure of external and internal structures of animals. The laboratory plan was executed with the help of AutoCAD and SketchUp programs, which enable the development of technical drawing in two dimensions (2D) and three-dimensional modeling.

Recently, health researchers have become interested in "eco-friendly" or "green" healthcare. One of the current trends in the green healthcare movement involves incorporating natural elements into health care settings to promote the health of patients and healthcare workers. Research based on Restorative Environments Theory (RET) provides insight into the rationale behind incorporating nature into the healthcare setting. RET posits that pleasant natural environments help promote stress recovery by increasing positive affect, decreasing negative affect, and reducing physiological arousal. However, the components of this theory have not been sufficiently tested using a controlled laboratory environment. The purpose of the present study was to provide a more rigorous test of RET than what is currently found in the literature by using a controlled laboratory- based design. Undergraduates from the University of South Florida were randomly assigned to view 1) no images, 2) neutral, non-nature images, 3) pleasant, non-nature images, or 4) pleasant, nature images during recovery from an anger recall task. Overall, the results of the present study did not demonstrate support for RET. There were no group differences in recovery time for any of the physiological variables with the exception of TPR. Those in the pleasant, non-nature condition took longest to recover. Further, there were no group differences in affect ratings with the exception of positive affect, which was higher for those in the no-image control condition. From an evidence-based practice framework, this study suggests that additional empirical support is needed before RET is used as a foundation to justify widespread adoption of nature-based interventions using media presentation to represent the natural environment.

Type II diabetes is fast becoming a growing problem in developed countries worldwide. Traditionally the median age for diagnosis was around sixty, but recent surveys have shown that the entire age distribution curve has shifted to the left. Western countries boast the worst statistics in which type II diabetes is being reported in children under the age of ten. At such a young age the disease often goes undiagnosed for long periods of time allowing considerable damage to occur. The incidence of type II diabetes is thought to be parallel with the growing rate of obesity associated with a characteristically unhealthy western diet. Type II diabetes is an extremely expensive disease to manage, and with the rapid growth of this pandemic our country will soon feel the economic burden of this disease. It is for this reason that cheaper medication needs to be investigated in the form of traditional plants, such as Sutherlandia frutescens. Prescription medication, such as tricyclic antidepressants, may also increase body weight or appetite thereby playing a role in obesity. The cause of weight gain in such cases may go unrecognized or lead to cessation of the medication with or without the practitioner’s knowledge or approval. It is therefore necessary to investigate the causative agents responsible for the excessive weight gain. Drinking water containing extracts of the S. frutescens, metformin (a well known type II diabetes medication) and amitriptyline (a common tricyclic antidepressant) was administered to three groups of ten male Wistar rats. The control group received water without any medication. The rat’s weight and food consumption was monitored throughout the trial and their oxygen consumption was also determined. Rats were sacrificed after four months of medicinal compliance and glucose uptake, in the presence and absence of insulin, was tested in epididymal fat, liver and muscle. Fasting plasma glucose levels, lipoprotein, cholesterol and triglyceride concentrations were also determined.

Ingeniero Civil de Minas / La División Goldex de la empresa Agnico Eagle Ltd., opera una mina subterránea ubicada en la ciudad de Val-d Or, Québec, Canadá. Debido a la geometría del yacimiento (zona GEZ) y las bajas leyes de oro, la explotación considera un caserón de grandes dimensiones, utilizando una combinación de los métodos block caving por su bajo costo y alta productividad; longhole stoping, buscando una fragmentación adecuada y otorgando flexibilidad en la operación; y shrinkage debido a la estabilidad que entrega a las paredes. A pesar de las consideraciones del método seleccionado, una de las preguntas más importantes de la faena a lo largo de su vida, es la estabilidad final de la mina. Estudios a través de modelos numéricos estiman desprendimiento de estéril proveniente del techo, lo cual ha coincidido con las mediciones reales, pero al momento de tomar la forma final del caserón, el desprendimiento ha sido considerablemente mayor. Lo anterior motiva el presente estudio que tiene como objetivo principal determinar la potencial recuperación de reservas de la mina Goldex, a partir de una revisión de antecedentes que defina los posibles escenarios esperados, con respecto a su estabilidad y la utilización de la herramienta de flujo gravitacional, REBOP. Para que REBOP represente de forma fehaciente el flujo es necesario realizar una calibración de éste, variando los datos de entrada a ingresar, dependiendo de las características del macizo rocoso, el diseño de la mina y su programa de extracción. Los resultados entregados por REBOP muestran un error de la ley estimada mensual de 0,20 [gr/ton] y una buena coincidencia entre los espacios de aire generados, por la extracción y la propagación del caving, medidos en la operación con los visualizados en REBOP. De lo anterior se concluye que REBOP como una herramienta de planificación a largo plazo permite obtener una estimación cercana de leyes y finos a partir de un plan de producción y una estrategia de extracción dada, ayudando de esa forma a la evaluación de distintos escenarios propuestos para la explotación futura de nuevas zonas u otras ya existentes. Calibrada la herramienta de flujo, se definieron 3 casos geomecánicos a evaluar: estable, inestable parcial y colapso. Para cada uno se consideraron además, 2 diseños posibles: 1 ó 2 niveles de producción; y 2 estrategias de extracción: uniforme y proporcional a la columna de mineral. Los resultados de las simulaciones entregaron que para los 3 casos el mejor VAN y la mayor recuperación, se obtiene utilizando 2 niveles de producción considerando una estrategia de extracción uniforme. La tabla siguiente resume los resultados obtenidos para cada caso, definiendo el diseño, estrategia de extracción, recuperación y VAN obtenido. Tabla: Resumen de resultados para cada escenario evaluado. Caso Diseño Estrategia de extracción Recuperación VAN Estable 2 niveles de producción Uniforme 97,9% MUS $ 828,77 Inestable Parcial 2 niveles de producción Uniforme 82,2% MUS $ 534,23 Colapso 2 niveles de producción Uniforme 70,0% MUS $ 492,47
