A presente monografia tem a finalidade de refletir como a imagem poética é construída na poesia concreta de Augusto de Campos. Para isso, será utilizada a teoria de alguns estudiosos, como Alfredo Bosi, Octavio Paz, Philadelpho Menezes, Aguillar, entre outros, para embasar a reflexão sobre a imagem poética que se desenha a partir da leitura da poesia por meio das palavras que compõem a produção artística. Há uma ênfase, durante a análise das poesias, nas palavras que as constituem, pois elas formam um elemento fundamental para a criação da imagem poética na produção da poesia concretista. O trabalho também reflete sobre a repercussão do movimento Concretista em décadas distintas (50,70 e 90) e em diferentes vertentes, como na música, nos âmbitos nacional e internacional, ressaltando a importância do Concretista para o enriquecimento da poesia, especialmente as compostas por Augusto de Campos. Também será mencionada a diferença entre a poesia visual e a poesia concreta. Para isso, serão explicitadas as suas peculiaridades e as suas propostas

The aim ofthis article is to discuss the existence ofan original writing utopia in Haroldo de Campos, which seems to be more important to his work than the concretist utopia. It is possible to understand the Haroldo's poetry project since the establishment of a parallel between the epic aedo and the haroldian attitudes concerning the invention and the tradition, taking them as difference in the constitution of Haroldo's identity. Once he assumes a impossibility to rescue the origin itself, the haroldian project turns to the 'jetzeit" and that, secondly Agamben is very contemporaneous.

This article examines philosophical and anthropological underpinnings of the Sich-Bewegen Theory, based on the phenomenological philosophy by Merleau-Ponty and social anthropology by Mauss and Geertz. It also considers implications for Physical Education Elementary and High School curricula aimed at forming emancipated, autonomous and critical individuals, taking the Physical Education Curriculum of the State of Sao Paulo as example. It concludes that the curriculum needs to imbricate into students'social life and take into account the challenges and issues from contemporary society.

The objective of the present work was to study the control of the dynamics of diatomic heteronuclear molecules interacting with electric fields created by lasers. Specifically in this work, the molecular photoassociation phenomenon will be analyzed. At this phenomenon, the atom's relative movement is described by a particle that moves in a morse potential well under the influence of an external time dependant force related to the external field. Based on the optimum control theory (OCT), it is presented at the present work laser pulses that alternate a given initial molecular state to a desirable end state, wich in this work was represented by the minimization of a cost functional that indicates how close. To do so, a computational sistem know as Genetic Algorithm (GA) was developed that can be characterizes as an extremelly eficient technique capable of scanning the solutions space and find results close to the optimum solutions

The experimental demonstration is one of the traditional activities used in the ambit of the Science teaching and of the scientific divulgation. However, this activity has not been fully explored yet in the classroom, because teachers have faced considerable difficulties due to the lack of demonstration equipment. In this work we present the explanation of an easy and low-cost assembly of an electric motor, to be used in Physics classes in High School. In addition, we employed Vigotski’s theory to guide this experimental activity in the classroom.

The acceleration of economic and scientific development caused by the production system and mechanistic science, have created new power structures and new political and social problems, including environmental ones, consolidating a period of widespread crisis in different spheres of society. In this context, reflection about the major causes of environmental problems is necessary in the field of environmental education. Therefore, considering that the current environmental crisis is directly related to the mode and the devices of production of the capitalist system, initiatives on environmental education should reflect, from a historical and dialectical process, on what is advocated by capitalist society. Considering the various theoretical-practical concepts and approaches in environmental education, the principles of Critical Environmental Education can provide conditions to confront the structural crisis that we are facing, through the educational process. It is a political process of reflection and critical appropriation of knowledge, attitudes, values and behaviors that aims to contribute to build a sustainable society from the social and environmental points of view. We intend to articulate it through the theoretical formulations of Historical-Critical Pedagogy with the purpose of presenting a reflection that may contribute to a pedagogic response to environmental issues, especially regarding the formation of teachers who develop projects in schools. Thus, this present study intends to highlight the contributions of the philosophy of praxis in the formation of environmental educators, grounded in theoretical aspects of Critical Environmental Education.

This study examines the relationship between theory and practice that emerges from two Environmental Projects that were carried out in a popular neighborhood of Bauru, SP, . In order to analyze the data, given the diversity of theoretical and practical approaches and concepts in environmental education, we chose as a theoretical foundation critical environmental education. Considering the techniques used in the methodological procedures of qualitative research in education, we elected, as a tool to collect information, content analysis. The results presented in this paper indicate the need to break the dichotomy between form (practice) and content (theory) in the environmental educational process, focusing on the systematized and historically constructed contents. Thus, we consider the environmental education process analyzed involve treating form and content as a dialectic unit.
