This project analyses in theory the transformations that have occurred in the information society in the range of the organizational communication, developing the internet historical trajectory as a technology of transformation. We highlight the cyber culture study as a cultural expression that emerges with the current society needs, observed by an optic that focuses on digital communication, emphasizing the digital environment as a space for information trade, in the interior premise of communication: the relationship. The organizations will be approached in the project through a channel for communication, in the digital range, besides the traditional forms. In regards to the enterprises we will study in depth the consumer of this society of consumerism, with a special look at the generation Y, deeply inserted in this virtual context, describing the current type of consumption, mainly the relations of consumption with the social medias. After this transforming process in which individuals are inserted in the digital environment we intend to focus in the corporate digital communication, analyzing the organizational digital communication in the contemporary society. We emphasize the theories of Public Relations, one of the main activities, able to do planning, to put together and execute the strategies that will be used in the social medias as a form of corporate digital communication. We explicit Twitter as a tool of the corporate digital communication, because it reaffirms the theories described throughout the research as one of the most essential social media to turn loyal the relationship between the consumer and the organization in real time, as an example is the organization “camisetaria” that became a success case in the social medias; we detail the participation of the company on Twitter and the reach of this network through it’s strategies in the corporate digital communication

As ações do homem têm causado danos à natureza, colocando em risco a vida na Terra, muitas vezes, pelo erro de se acreditar na infinitude dos recursos naturais. Torna-se assim necessário um processo de educação para a formação da consciência ecológica, que pode ser definido como Educação Ambiental. A Botânica é o estudo do Reino Vegetal, o que envolve seus aspectos estruturais, sua fisiologia, bem como seu papel no meio ambiente, sendo que este último tem recebido muita ênfase, dada a importância dos vegetais na manutenção das condições da vida. Dada essa forte relação entre a Botânica e a Preservação ambiental, torna-se relevante a busca por propostas de ensino que articulem estes dois campos. Documentos como os Parâmetros Curriculares Nacionais, do ensino médio e do ensino fundamental, assim como o Referencial Curricular Nacional para a Educação Infantil incentivam uma abordagem contextualizada dos assuntos relacionados ao meio ambiente, de forma a permitir ao aluno, não apenas a compreensão da diversidade e complexidade dos seres vivos, mas também, a percepção de seu próprio papel como agente transformador do ambiente. No nível infantil, a educação ambiental é um dos temas que pode e deve ser abordado, favorecendo a formação da consciência ambiental que se deseja, bem como despertando o interesse pelo ensino de Botânica para que este permaneça nos próximos níveis de ensino e para a vida. A importância das atividades práticas na Educação Infantil é inquestionável e o jogo é uma das atividades que favorece o desenvolvimento da criança, podendo ser utilizado como material didático capaz de auxiliar na formação de indivíduos críticos e criativos. Reconhecendo-se a importância da abordagem dos conhecimentos de Botânica para o desenvolvimento de temas de Educação Ambiental e a necessidade da...

According to the Informational Society of the twentieth century, man develops society of the spectacle, where life becomes virtual and the individual ceases to be a spectator becoming the protagonist of wikiciberepopéia and organizations seeking to gain the attention and time of its consumers through new communication strategies. If the great epics of mankind brought mythical heroes, divine, with powers (mostly above the mortals), in the era of new technologies, the common man is in the hands the opportunity to become the hero of his own ciberepopéia. Increasingly resistant to traditional advertising, the new model of media consumer, the prosumer, the storytelling is transforming into one of the main communication tools of contemporary organizations. Offer your audience a creative and relevant content across several media platforms is a major brand positioning strategies currently used, in addition to providing the transmission of values and organizational principles in a subjective manner. Storytelling where objects are extensions of the human body (eg, the cell can be treated as an extension of the ears) is a strong indication of a technocratic society, because we can consider the new technologies as extensions of the human brain (as new store technologies, create meanings, share information through a specific language) and the individual who is on the edge of new technology ends up being excluded from certain social events. This new world tends to put an end to separation between seemingly contrary ideas, such as reality/fiction, natural/cultural and the man who emerges from this medium is not the creator, but rather, transforming what already exists. The current human evolution takes place from about half the human mind and tell stories that go beyond the media saturation that really emocionem and who have a real meaning for those who listen, to be interconnected with the socio-environmental reality of this new consumer, is a major chall...

This work aims to understand the ways that have led Brazilian geographers to use the gender category as an analytic element in other to understand the production of space, through the theoretical perspective of Feminist Geographies. Thus, it is important to consider, in the history of geographical science, the theoretical and methodological foundations which enabled the inclusion of gender in researches, since this subject belongs to the field of Anthropology and Sociology and it rarely appears in geographical investigations. It is understood that the gender, as an analytical category of intertwined social relation of space, comprising not only the femininity as well as masculinity and transexualities, analyzed in a relational perspective. However , greater emphasis on the understanding of woman as an agent of space will occur, due to the importance of taking the role of women in building the world out of the hidden of history. Therefore, some works produced in Geography in Brazil will be presented and discussed in order to give visibility on the treatment of space and gender relationship

Partimos da constatação do distanciamento historicamente efetuado entre o homem e a dança, iniciando nossos questionamentos acerca dos impedimentos localizados na cultura para tal configuração. Identificamos mecanismos de poder que estabelecem este afastamento por questões ligadas ao gênero masculino, refletindo preconceitos enfrentados por bailarinos e a criação do estereótipo do ser homem, baseados numa perspectiva empobrecida a seu respeito. Com isso nos questionamos sobre o que o homem perde ao deixar de dançar. Necessitamos tentar definir do que se trata o masculino, cuidando por abandonar os formatos fornecidos culturalmente, por estarem sob a ótica das relações de poder predominantes. Após empreendermos um esforço nesta direção, percebemos com maior clareza a função do masculino enquanto força criadora que, em consonância ao feminino, atua nas mais diversas instâncias do criar, num movimento constante que o sustenta. Neste momento nos deparamos com as formas socialmente instituidas destas duas forças e em como passaram a atuar após a perpetuação dos modos de vida patriarcais nas sociedades ocidentais. Aqui nosso foco recai sobre o processo de criação na dança e em como esta se encontra afetada com as políticas de dominação nos aspectos destacados como o gênero masculino, a multiplicidade e a intensidade. Estes aspectos, ao sofrerem limitações ocasionadas pelo formato estabelecido sobre o masculino, tornam-se pontos-chave para a análise da dança cênica brasileira em seu ensino e criação ao mesmo tempo em que mostram-se como potências de seu aspecto transformador. Percebemos processos de resistência às políticas dominantes de anestesiamento e colonização dos corpos, aqui focados sobre o homem, pensando o movimento como força capaz de subverter-se às formas dominantes limitadoras

This paper shows the modeling and control of a single-phase full-bridge inverter with high-frequency transformer that may be used as part of a two-stage converter with transformerless DC-DC side or as a single-stage converter (simple DC-AC converter) for grid-connected PV applications. The inverter is modeled in order to obtain a small-signal transfer function used to design the P+Resonant current controller. A highfrequency step-up transformer results in reduced voltage switches and better efficiency compared with converters in which the transformer is used on the DC-DC side. Simulations and experimental results with a 200 W prototype are shown. 1

Among the various school functions in capitalist society there in the literature and common sense that the school would have a central role in correcting social inequalities produced by the capitalist mode of production. We see, in today's society, children and young people who moved by the desire to get out of where they are, usually on the outskirts, in a vulnerable situation, seek growth through the study; They see it as a way out to another reality with more opportunit ies and chances for improvement, both as regards their quality of life, and even want to change, change and influence their own reality or part of it, with the knowledge learned in school. On the other hand, there are theorists who maintain that the school reproduces the basic features of the social structure and the current system of power in society. Our goal is to discuss the transformative potential of education as opposed to its role of reproduction of social inequalities, through the essential role of the teacher, who has a high profile role when it comes to change. The teacher is one of the first professionals that we remember when we turn to the school and refer to the systematic teaching. But sometimes forms of education present in the school, afflicting much of children and young people and are characterized in order to favor certain classes and eventually stop the growth and development of those who do not meet the required standards. In this paper we intend to compare two lines of thought, alluding to pedagogical activities in class, the Paulo Freire, which brings the teacher's figure with a responsible actor for lead students to reflection of their practice; and Pierre Bourdieu, which considers the pedagogical practice as an act of imposition of values of the ruling class. The work will address the issue from literature
