Analises da nanociência e nanotecnologia na perspectiva de ciência, tecnologia e sociedade cts

In this contribution, we discuss and analyze some aspects of nanoscience and nanotechnology, based on the approach kwon as Science, Technology and Society (STS), as well as the prospects of Philosophy of Technology. In this context, we specify the constitute the nanoscience and nanotechnology analytic research field. I is also reported its genesis and limits, emphasizing the impacts of nanotechnology in the development of the contemporary society, such as the possible benefits and problems associated to the use of nanotechnology, as well as environmental impacts, doubts and uncertainties that permeate this areas, in addition some ethical questions and public policies for the sector are analyzed.

Nanotecnologia e nanociência em livros didáticos de física do nível médio: discursos sobre a tecnologia e a educação científica e tecnológica

In this contribution, we analyze conceptual approaches to nanotechnology and nanoscience in recent issues of secondary education of Brazilian physics textbooks. We analyzed fifteen collections of Physics textbooks of recent editions, however, only two books, belonging to different collections incorporate considerations about nanotechnology and nanoscience in their approaches. We focus our analysis on three aspects, namely: the place dedicated to approaches to nanoscience and nanotechnology, notions about technology and its contributions to critical scientific education. This is a qualitative research; it was used as conceptual approaches the Philosophy of Technology, The Discourse Analysis (DA) and Science, Technology, Society (STS) concepts. We found that in two examined textbooks the approaches to nanoscience and nanotechnology is a complementary description of modern physics, associated with quantum theory. In this context, the concepts of nanoscience and nanotechnology focus superficially in the genesis of the field and some possible areas of applications. It was not identified in all textbooks warnings about the potential risks to human health and the environment from the use of nanotechnology and nanoscience. We understand that textbooks approaches about nanotechnology and nanoscience round a instrumental technological perspective, however keep away from the scientific and technological critical education.

Opinião pública, autonomia (relativa) e um novo contexto tecnológico: uma discussão sobre jornalismo especializado em tecnologia

De um lado, tem-se o fato de que o jornalismo auxilia na formação da opinião pública ao ocupar o lugar de “confiabilidade” na sociedade contemporânea. Do outro, a liberdade do público para consumir conteúdos na web, e uma relativa autonomia para produzir seus próprios conteúdos. A equação que soma a formação da opinião pública pelos jornais à autonomia do público, tem como resultado um certo “descontrole” da opinião pública por parte dos jornais, e evidencia a relevância de estudos acadêmicos para tentar entender essa nova realidade. Este artigo traz um diálogo entre ideias postas por Nilson Lage (1996), John Keane (1998) e Paul Levinson (2012) a respeito das mudanças estruturais na sociedade e a formação de opinião pública. O jornalismo especializado em tecnologia, e a presença de temas ligados à cultura livre nessas páginas é o que permeia a discussão.

A representação temática da tecnologia nos jornais brasileiros e sua configuração mercadológica diante de uma perspectiva de conceito social

This article is part of the result of the Master's thesis of the author, guided by coauthor, and presents a theoretical and conceptual reflection on the representation of Technology in thematic sections Technology in four Brazilian newspaper sites. The fundamental hypothesis is that these editorials prioritize issues that meet market interests of companies in the sector and may be leaving out important social and cultural issues to the understanding of the relationship between technology and society. The study is itself oriented by prospects of journalistic theming and specialized journalism, from a quantitative analysis involving the websites from newspapers of Technology sections O Estado de S. Paulo, Folha de S. Paulo, Gazeta do Povo and Correio Braziliense. The study confirms the hypothesis that representation of Technology in newspapers is primarily the marketing, have not corresponding to an expectation of social and cultural concept. In addition, it is noticed that the editorial in question do not have specialized journalism characteristics, despite of potential generated by thematic segmentation.

Tecnologia disseminando a arte: quais as perspectivas para o futuro da TV Digital?

Digital Television offers a resolution of highdefinition images and the possibility of interaction with the user. There is an estimate that by 2018 all municipalities in Brazil have digital signal availability and thus there will be a wide spread of Ginga. Ginga is a technology developed for digital television, which runs between the operating system and yours applications. However, the extensive use of Smart TVs would invalidate this technology? This article to cast a look on the topic, arousing reflection that effect and seeking bring issues that link the advantages and disadvantages of the two technologies, considering the current situation of Digital TV in Brazil.

Aplicação da tecnologia 4G em projetos de telefonia

This paper presents a study based on bibliographic research on LTE technology, chosen for the fourth generation of mobile phones, and the current status of implementation of 4G network in Brazil. The change in user behavior, which now uses data over the voice services, requires transmission networks to be increasingly robust and fast to enable the viewing of videos and use of other platforms that require internet connection. The retrospective of the development of mobile technologies, from 1G up to 4G that is currently used, shows the long road until it came to appliances and how the phone is used nowadays. Finally, the popularity of smartphones and hence the growing number of people with access to 4G networks, demanded new researchs for the development of future generations technologies in order to achieve the demand for speed enabling significant changes in user experience
