Corpos em cena: o fazer pedagógico na ginástica rítmica

O estudo em foco objetiva analisar a concepção de corpo dos professores de Educação Física que atuam com a Ginástica Rtmica (GR), identificando pontos de convergência e divergência entre o discurso e o fazer pedagógico. Os sujeitos pesquisados foram quatro docentes do sexo feminino e um docente do sexo masculino que desenvolvem suas ações pedagógicas com a GR em espaço escolar e extra- escolar. Como suporte teórico, optei em dialogar com as ideias de autores como Moreira (1995), Gaio (2007), Kunz (1994) entre outros, que discutem acerca de corpo, GR e prática pedagógica na Educação Física. A metodologia adotada envolveu uma revisão bibliográfica para efeito de consolidação do referencial teórico, e uma pesquisa de campo constituída de entrevista estruturada e observação. Para efeito de análise e coleta dos dados da entrevista fiz uso da Análise de Conteúdo: Técnica de Elaboração e Análise de Unidades de Significados elaborada por Moreira, Simões e Porto (2005). A observação teve como base a pesquisa descritiva como sugere Rampazzo (2005). Os resultados do estudo indicam que dois, dos cinco professores sujeitos dessa investigação ainda percebem o corpo de forma fragmentada e distante da realidade que o circunda, entendendo-o apenas como objeto para intervenção de técnicas, de táticas, etc. Três professores transitam em meio à concepção de corpo enquanto sujeito e também enquanto objeto, mas os primeiros apresentam apenas vestígios que se mostram muito tímidos. Apesar das convergências e divergências entre as idéias que têm de corpo, todos os cinco professores apresentam em sua prática pedagógica, sinais de que adotam uma concepção mecanicista. Esse trato se dá na medida em que os docentes deixam de considerar a realidade dos alunos na construção do planejamento de ensino, encarando-os como instrumento de transmissão e reprodução e não como sujeitos do processo ensino-aprendizagem. Nesse sentido, a comunicação, no decorrer da ação pedagógica, é efetivada por meio da autoridade máxima dos professores que determinam e controlam todos os movimentos que devem ser realizados nas aulas, cerceando, sobremaneira, a criatividade, a criticidade e o desenvolvimento da autonomia dos alunos.

Quebra dinâmica da simetria quiral na pseudo eletrodinâmica quântica em (2 + 1) dimensões

No presente trabalho, estudamos a quebra da simetria quiral na pseudo eletrodinâmica quântica em (2+1) dimensões usando o formalismo das equações de Schwinger-Dyson e investigamos as semelhanças deste modelo com a criticalidade encontrada na EDQ₃ e EDQ₄. Usando a aproximação “quenched-rainbow”, mostramos que existe um acoplamento crítico α_cc = π/16, acima do qual existe a geração de massa para os férmions e portanto, ocorrendo a quebra da simetria quiral. Também estudamos o caso com N campos fermiônicos usando a expansão 1/N na aproximação “unquenched-rainbow”, onde obtemos um número crítico N_c abaixo do qual a simetria quiral é quebrada e, para valores acima, a simetria é restaurada. No limite de acoplamento forte (g -- ∞), mostramos que este número crítico é o mesmo encontrado na EDQ₃ na expansão 1/N.

Fatores de risco em cadeia de suprimentos do setor aeroespacial: aspectos qualitativos e quantitativos

The lack of risk management can generate disruption in the supply chain, and there is little literature related to the aerospace industry. This article aims at identifying the risk factors for supply chain of the main Brazilian aircraft manufacturer. Nine risk factors specific to aircraft manufacturers were identified: Environmental, Natural and Political, Supply Chain, Business Strategy, Product Management, Indicators, Organization, Productivity, and Quality and Information System. These factors were quantitatively evaluated with respect to their criticality using the Analytic Hierarchy Process (AHP). The Quality and Productivity factors were considered the most relevant in this study, which can be classified as a single case study. The necessary data were obtained through interviews with professionals from different areas of the studied enterprise.

A Construção do Conhecimento na Atualidade: Um Olhar Sobre o Impacto da Tecnologia

In the paper analyzes the process of knowledge construction in the news regarding the emergence of massive information and communication technologies. In this context, through a qualitative approach, first we examine the potential of production, dissemination, access and use information in a technocratic perspective, and secondly, the negative impacts stemming from the computed mediation, mainly linked to the complexity of policies of democratization of access to information and loss of criticality of science. The focus of this review focuses on the current model of information search and knowledge construction through the Web, outlining aspects inherent to the process in general. Similarly, envision different contributions of information science for the systematization of human knowledge, guided through the social actions of professionals working in various fields, with emphasis on the information representation and retrieval. It is hoped that work can contribute to the current thematic reflection on the production, dissemination and use of information as well as on digital inclusion policies.

Through empirical research - qualitative and quantitative – was observed, as a result, that digital media is still gaining ground in political campaigns and the effectiveness of actions organized through on line universe which are beginning to be proven, from the perspective of students. Furthermore, it was possible to realize the criticality that is developed within universities making students able to analyze the context in which they are in

Análise crítica de contratos técnicos como ferramenta para melhoria da gestão da manutenção

Currently, due to the highly competitive search among industries are becoming more tools for managing product that provides higher availability and therefore profitability. Maintenance as a strategic sector and of fundamental importance in business, it seeks to maximize availability and available resources, minimizing costs and waste, which directly impacts the company's results. The present work has as main objective the review of contracts for maintenance services for companies contracted by a chemical company in the Paraíba Valley, since most of its maintenance services are outsourced, and raise these contracts which are more critical and higher risk to the company's success, thus creating a tool for decision-making by maintenance managers in the act of seeking renewals or new contracts to provide services. As a result after drawing up a standard procedure for contracting of services and a better structuring of the same, we developed a method for the calculation of the criticality of the contracts and based on these calculations, charts were prepared which showed that the current scenario of maintenance contracts the company studied. Thus it is possible to evaluate the contracts which are most critical to the success or failure of the company studied, and also pave the way for further studies on how this criticality of a contract can affect the relationship, the contractor x contracted

Aplicação dos conceitos de RCM e a ferramenta FMEA no aumento de confiabilidade em equipamentos de uma indústria química

The growing demand for quality at competitive prices and fast production process put to the test function in the industrial Maintenance. The need for equipment with high availability to fit this fierce competitiveness makes maintenance becomes essentially reliable. Despite this current context, many companies still have an old view of maintenance, focused only on corrective services, and proposals for change are often neglected due to the sense of urgency day to day. Thus, this study aims to demonstrate through theoretical applicability of simple tool, but of great value in increasing reliability within the maintenance sector of an industry, applying the concepts of Reliability Centered Maintenance – RCM and Analysis tool Failure Modes and Effects – FMEA in equipment of a chemical company directly involved in the manufacturing process of the brake fluid, which this product is used in vehicles around the country. That way, you can identify the types, occurrence and criticality of each failure and evaluate assertively decision making for each device, avoiding unnecessary downtime and potential failures of the same

Estudo das propriedades mecânicas do aço SAE 1312 modificado ao nióbio

The study of mechanical properties of high-alloy special steels is of great interest of the steel industry due to the great demand by companies that manufacture automotive components of high criticality, and also because of its high commercial value. However, the development of this type of alloy metals demand highly technical knowledge. Among these extremely important kinds of steel, the subject which is the interest of this study is the special steel modified by niobium. The manganese and niobium are the main alloying elements in the composition of these steels, both of them increase the stability of the austenite region, however, manganese increases the hardenability and tensile yield strength, and niobium increases the mechanical strength and promotes refining the grain. The mechanical characterization of steel SAE 1312 modified the niobium was made in order to gain a better understanding of the influence on the mechanical properties caused by aging at different temperatures and for different reductions in the drawing of gauge material. This characterization was made by means of tensile test and hardness. This material showed an increase in yield strength and hardness when gauge with large reductions during the wiredrawing, but when subjected to aging temperatures higher than 300 ° C had a slight loss of these properties
