Percepção de professores da educação infantil e do ensino fundamental sobre sua prática de educação ambiental

A pesquisa aqui apresentada situa-se na linha da formação de professores em relação à prática pedagógica voltada à Educação Ambiental com olhar da transversalidade dos múltiplos saberes que envolvem essa temática. Adoto pesquisa qualitativa, uma vez que tenho a interpretação da comunicação dos sujeitos como principal processo para compreender os modos e as razões de sua prática docente em Educação Ambienta! Tenho como objetivo central: 'identificar modalidades de práticas educativas de educação ambiental na educação infantil e no ensino fundamental a partir das percepções dos professores sobre elas'. Com intuito de responder a pergunta norteadora da pesquisa que é: Que modalidades de práticas de Educação Ambiental integram a prática docente de professores da Educação Infantil e do Ensino Fundamental e como são por eles justificadas? Faço isso, utilizando as falas (manifestadas em respostas a questionário) de cento e quinze professores atuantes na educação infantil e no ensino fundamental, em situação de formação continuada que cursaram o módulo "Fundamentos da Educação Ambiental" do Projeto Piloto do Programa EDUCIMAT- Rede Nacional de Formação Continuada de Professores de Educação Básica-, no ano de 2005. O referido módulo foi ministrado em dois momentos, com duração de seis dias cada, desse modo, além do questionário utilizei também diários de campo, a fim de obter registros descritivos e analíticos como subsídios para melhor entender as respostas verbalizadas no questionário pelos professores investigados. Organizo as modalidades identificadas nas práticas em educação ambiental dos professores investigados em quatro categorias (Pedagogia Dialógica, Pedagogia Normativa Ecopedagogia e Cidadania,) buscando recorrências e singularidades entre os professores investigados com construções e desconstruções de percepções e saberes, em diálogo permanente com a literatura. Seguindo o paradigma da transversalidade ressalto, nesta pesquisa, o olhar multifacetário da formação do educador ambiental com o propósito de contribuir para que outros professores reforcem seu papel como agentes de transformação social e tomem iniciativas de desenvolver saltos qualitativos que permitam a inclusão, o desenvolvimento e a efetivação da educação ambiental de forma transversal e interdisciplinar em prol da melhoria da qualidade de vida do nosso planeta.

Análise morfológica do músculo gastrocnêmio medial de ratos submetidos a um protocolo de treinamento concorrente

The aim of this study was to analyze the morphophysiological changes of medial gastrocnemius muscle (GM) of Wistar rats underwent to eight weeks of concurrent training (TC). We used fifteen male Wistar rats divided into three groups with five animals each: baseline (LB), control (C) and trained (T). The TC consisted of aerobic endurance training in swimming (TRA) and a forced training (TF) in the same session, three times per week, for eight weeks. There was an increase of 4.4% in the comparison between average cross section area of the GM in animals of groups T (4905,5 ± 77,1µm²) and C (4699,9 ± 78,3 µm²). It is concluded that concurrent training was effective in causing hypertrophy in GM of rats.

On the Study of Complex Impulsive Systems

The article investigates complex impulsive systems in which the so-called controlling systems jumps effect emerges. In particular, this research includes the correctness of the solution to the impulsive control system and approximation lemmas. A 3D model example is provided which illustrates the relevance of the considered approach to the study of complex impulsive systems.

The dynamic behavior of a cantilever beam coupled to a non-ideal unbalanced motor through numerical and experimental analysis

An excitation force that is not influenced by the system state is said to be an ideal energy source. In real situations, a direct and feedback coupling between the excitation source and the system must always exist at a certain level. This manifestation of the law of conservation of energy is known as the Sommerfeld effect. In the case of obtaining a mathematical model for such a system, additional equations are usually necessary to describe the vibration sources with limited power and its coupling with the mechanical system. In this work, a cantilever beam and a non-ideal DC motor fixed to its free end are analyzed. The motor has an unbalanced mass that provides excitation to the system which is proportional to the current applied to the motor. During the coast up operation of the motor, if the drive power is increased slowly, making the excitation frequency pass through the first natural frequency of the beam, the DC motor speed will remain the same until it suddenly jumps to a much higher value (simultaneously its amplitude jumps to a much lower value) upon exceeding a critical input power. It was found that the Sommerfeld effect depends on some system parameters and the motor operational procedures. These parameters are explored to avoid the resonance capture in the Sommerfeld effect. Numerical simulations and experimental tests are used to help gather insight of this dynamic behavior. (C) 2014 Elsevier Ltd. All rights reserved.

A indução da potencialização pós-ativação através dos saltos: pliométrico e vertical

The Post-Activation Potentiation (PAP) offers a proposal to optimize the production of strength and muscular power when performing exercises near maximum to actions previously assessed . The present study aims to show the activation process of postactivation potentiation (PAP) through vertical and plyometric jumps, and explain the user function of these movements. The ratio of post-activation potentiation resulting from plyometric and vertical jumps and explosive strength in the lower limbs aims to improve the potency and maximal strength, proven through studies and protocols detailed here. The results of this research come can be applied both for athletes and for individuals with experience in strength training and jumps (sports like volleyball, basketball and handball). The study was conducted through a literature review, conducted in scientific journals indexed in major databases (PubMed, ISI-Web of Science, SCIELO), books and academic papers (theses and dissertations)

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Numerical and experimental investigation of a vibration system with non-ideal vibration source

An excitation force that is not influenced by the system's states is said to be an ideal energy source. In real situations, a direct and feedback coupling between the excitation source and the system must always exist. This manifestation of the law of conversation of energy is known as Sommerfeld Effect. In the case of obtaining a mathematical model for such system, additional equations are usually necessary to describe the vibration sources and their coupling with the mechanical system. In this work, a cantilever beam and a non-ideal electric DC motor that is fixed to the beam free end is analyzed. The motor has an unbalanced mass that provides excitation to the system proportional to the current applied to the motor. During the motor's coast up operation, as the excitation frequency gets closer to the beam first natural frequency and if the drive power increases further, the DC motor speed remains constant until it suddenly jumps to a much higher value (simultaneously the vibration amplitude jumps to a much lower value) upon exceeding a critical input power. It was found that the Sommerfeld effect depends on some system parameters and the motor operational procedures. These parameters are explored to avoid the resonance capture in Sommerfeld effect. Numerical simulations and experimental tests are used to help insight this dynamic behavior.
