The Physical education has as objective the students integration in the body movement culture, forming citizens to reframe different cultural aspects of the physical activity, enabling a more critical look. Currently selecting how the body movement culture has been widely approached by Mass Media it is detected a new pedagogical possibility. The several media equipment massively bomb (images, sounds and information) interfering on how the students interpret the reality, since they are exposed to these multiple information and at the same time are absent of a more critical look about what they receive. In this way, the objective of this work was to perform a research in the news/articles from the Jornal A Folha de São Paulo, that allows the development of classes based on the elements of body movement culture and apply them in a public school from Rio Claro-SP city, to detect possibilities and difficulties in the work with the media in the school environment. It employed a qualitative research. The data obtained in this study indicate that the media shows up as a good teaching tool for teaching physical education classes, since students found the classes to enriching the learning process, highlighting topics such as innovation and the closeness they had with the worked information. However, it is necessary to develop further studies to raise other possibilities as well as alternatives to deal with this new reality of the school context

This work has as purpose to show what are the influences of media in the education and in the shaping the thinking and understand that ideologies are present in the films used in the classroom in kindergarten. For this, I directed the discussion beginning by concepts as Ideology and its more different definitions by several thinkers over the years, the thinkers of Critical Theory of Frankfurt School, called “frankfurtians” of first and second generation of this school, also making an association between Cinema and Education, evidencing concepts involving this association as Cultural Industry, using films properly in classrooms in kindergarten, with the teacher as mediator and then discussed what amounts of movies on children's education, how they assist and deepen the knowledge developed by students in schools of infantile education. Additionally, they are exposed the different opinions about the subject Film and Education for students from kindergarten, what benefits and what disadvantages in the use of films, the different opinions on the subject. We also discuss, in this work, the ideologies present in three films produced by Walt Disney, they are Cinderella, Snow White and the Seven Dwarfs and Alice in Wonderland, relating them to how they can contribute to the development and learning students in kindergarten. I associated more as possible the previous discussions to analyze the ideologies present in these films, by summarizing these, and decomposing them through an analysis tool called frame. Finally, I completed everything that was discussed and analyzed, which students in kindergarten may develop with the use of films in schools, what they contribute, in some way, for the learning and education of students as viewers using the school as access to different cultures and the teacher as a mediator of this relationship

Corporative media, represented by TV, radio, press and internet conglomerates, is responsible for the biggest portion of audience and public all over the world. The commercial media was built upon media concentration and monopoly strategies and this business aims society’s economic and political control. Unfortunately, they don’t represent the biggest portion of population’s interests and, because of that, corporative media faces a crisis moment while alternative means of communication rise from the initiative of professionals who are committed to society’s marginalized sectors. Radical media intends to express a variant vision about hegemonic policies, priorities and perspectives. Citizen journalism is one of radical media arms and this research proposition is to analyze the business model of commercial media in Brazil and in the world, its means of production, and compare them with citizen journalism methods. This work also intends to analyze radical media and how it is opposite to corporative media by studying Escola de Notícias, an educommunication project from São Paulo

This project aims the verification of doses in canines and felines to chest and coxal exams due to the transition from screen-film to computed radiography system. It also seeks a possible optimization of the new techniques employed in this new system. The study was carried out in Diagnostic Imaging service in Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo using a conventional x-ray equipment. Initially, data about the physical characteristics of animals and the technique currently used in computed radiography was collected for each of 80 chest and 16 coxal X-ray examinations. The animals were divided into different groups according to the body weight. For each group, were calculated the averages of each item: thickness of the region to be imaged, voltage, current, exposure time, current-time product, size of film used, presence or absence of bucky and focus (small or large). The techniques have been reproduced in phantoms (representative of the thickness of the animal) in order to collect the air kerma entrance. Based on the average of intermediate size M group (weights less than 5 kg for cats and from 10.1 kg and 20 kg for dogs) analysis of image quality using three devices test patterns were made consisting of the evaluation of spatial resolution, low-contrast resolution and contrast-detail. In general, the results showed the dose animals decreased with the use of computed radiography and was possible to preliminary optimization of some techniques used currently in CR

In this sense, the research has as objective the reflection about democracy, the centrality and conglomeration media in society and what is affecting public broadcast organizations. So has too the intention to defend the performance of professional public relations in this context, due to its humanistic and strategic characteristic. Through literature review, observation of programming of Radio FM UNESP Bauru and interviews with employees, it is perceived that the vehicle radio for its intrinsic characteristics has great potential democratization, when this character in public can promote citizenship. There was also observed the demand for professional public relations, assisting the organization to recognize themselves as a social institution, defining its mission, its goals, its vision and policies, with objective to make two-way symmetrical communication to the public

In the last years, environmental issues are being gradually addressed because of awareness regarding the limitation of natural resources for the maintenance of life on Earth, and the role played by the media in reporting on various issues that are related to the theme. In the industrial sector, this topic becomes ever more present in its planning. With the increase of production activities, the generation of waste causes many complications, both in industry and in the environment. For this reason laws and rules were created so that such problems are minimized, thus causing less impact on the environment. In this work was a study of the possible environmental impacts in a soybean crushing industry, situated in the city of Osvaldo Cruz, São Paulo state, detailing the sources and impacts of waste generation, and associate them relevant laws. From this, measures were proposed measures of adequacy involving compliance with commitments to environmental agencies, relevant requests of buyers and / or suppliers and improving environmental performance

This research is aimed at discussing the ways in which social agents influence global warming, analyzing the discourse of social actors involved in the debate on climate change, since there is a wide divergence in the scientific community about how man is able to modify the climate on a global scale. In fact the debate that permeates the issues beyond the limits of science and enter into a political-economic framework that takes extraordinary proportions. This emphasis can be very unscientific in the fundamental design concepts, or even creating a trivialization of the media. The main way to convey these concepts is to disclose them in the media, but the media has enormous power to transform the concepts and often manipulate the news by creating a common sense goes against the interests of the scientific community. Thus was conducted extensive research in major newspapers and magazines that move in the country. We surveyed the first two papers which were: “Folha de S. Paulo” and “O Estado de S. Paulo”, during the period from January 2000 to December 2008, totaling 3285 units for the newspaper Folha and 2555 for the newspaper Estadão. Subsequently a survey was made of data published in two journals that move at the national level, and these are the magazines VEJA and ÉPOCA for the same period. By performing these steps, it was concluded that several factors involving the media and climate change, such as topic relevance, types of approaches, perspectives of analysis, the staff development, supplies, among other factors of utmost importance for building news. As a result we can say that the media in fulfilling its role of mediator scientific, disclosing only a vision that permeates the scientific debate. The newspaper media, especially newspapers, has an informative and instantaneous. Often this preoccupation...(Complete abstract, click electronic access below)
