Desse modo, o objetivo mais amplo da pesquisa foi o de mapear a leitura na tela do computador - conectado à Internet – entre seis sujeitos do ensino fundamental de uma escola pública do município de Assis – SP. Os sujeitos foram observados em situação de leitura no impresso e na tela, para que , entre outros pudessem ser observados comportamentos transferidos de um suporte para o outro, tanto do impresso para a tela, como da tela para o impresso. A metodologia que guiou a execução do trabalho foi o estudo etnográfico e grupo focal uma vez que era de nosso interesse a elaboração de conhecimento calcado na observação in loco de comportamento humano. Foram analisados os modos de operar o pensamento emergentes da prática de leitura no ambiente virtual, bem como sua possível relação com outras mídias Os dados coletados foram categorizados com base na análise de conteúdo e refletidos à luz de bibliografia especializada, em que se destacam como autores centrais: Chartier (1999; 2001; 2002; 2005), Eisenstein (1998), Nielsen (1997; 2006), Bakhtin (2000; 2004) e Mcluhan (1969; 1972). Foi possível verificar que a leitura na tela é rápida, como um escaneio do texto, em que o leitor parece mobilizar estratégias de antecipação e previsão de seu trajeto de navegação. Além disso, a atribuição de sentido na leitura se dá por meio de um processo de união de fragmentos de informação; a experiência hipertextual faz do leitor co-autor dos textos que lê. Por fim, é preciso dizer que alguns leitores se encaminhavam para a leitura na tela com as estratégias do impresso, o que em alguns casos comprometia o encontro das informações buscadas. / This work is characterized as a study concerning the new practical and the emergent ways of reading in the context of cyberspace, looking for to reflect on the new implications of these practical for the formation of the reader in the school. In this way, the objective amplest of the research was to characterize the reading in the screen of the computer - connected to the Internet - enter six students of the basic education of a public school of the city of Assis - SP. The students had been observed in situation of reading in the printed matter and the screen, searching, among others facts, to observe behaviors led of a support to the other (in such a way of the printed matter for the screen as of the screen for the printed matter). The methodology that guided the execution of the work was the study ethnographic of case, a time that was of our interest the elaboration of knowledge based in the comment in leases of human behavior. The collected data had been categorized on the basis of the reflected analysis of content and to the specialized bibliography light, where if they detach as authors central offices: Chartier (1999, 2001, 2002 e 2005), Eisenstein (1998), Nielsen (1997 e 2006), Bakhtin (2000 e 2004) and Mcluhan (1969 e 1972). As results, it was verified, from the actions of the showed students, that the reading in the screen is fast, an scanning of the text, where the reader must mobilize strategies of anticipation and forecast, the text and its passage of navigation. Moreover, the felt attribution of in the reading if gives by means of a process of union of fragments of information. The hipertextual experience makes of the reading co-author of the texts who reads. Finally, the ways had been analyzed emergent to operate the thought of the practical one of reading in the virtual environment, as well as its possible relation with other Medias.

Orientador: Antonio Carlos de Jesus / Banca: Nelyse Apparecida Melro Salzedas / Banca: Maria Cristina Gobbi / Resumo: Considerando que os estudos sobre a produção de revistas especializadas, ainda não tem conhecimento científico solidamente produzido, apresento nesta dissertação relato fruto de pesquisa bibliográfica e de campo sobre o processo de gestão da informação, mais especificamente da criação a recepção da revista todateen, destinada ao publico adolescente, com uma singular característica, produzida integralmente no interior do Estado de São Paulo e uma das publicações da área de maior tiragem. O estudo objetiva também, demonstrar o funcionamento do processo de gestão da informação na produção de mídia impressa e especializada. A dissertação se estruturou com pesquisa histórica, bibliográfica e documental para assegurar o seu desenvolvimento estruturado em três partes: aspectos históricos e evolutivos das revistas no Brasil, a origem e o desenvolvimento da Editora Astral, o espaço contextual da produção e finalmente o processo de gestão da informação na revista todateen. Portanto a principal contribuição desta dissertação é demonstrar, pelo foco da gestão da informação, os processos pelos quais as informações passam até transforma-se em conhecimento disponibilizado no mercado editorial, através do seu conteúdo aqui demonstrado e analisado. / Abstract: The present work objectified to demonstrate as the process of information management in the production of a printed media, specifically, the magazine todateen. The research if structuralized, mainly, in the bibliographical research and registers, collating the historical moment for which had passed the magazines since that they had started in Brazil, until the present. Also to describe, minutely, the birth and the trajectory of the Alto Astral publishing company in its 19 years of existence, as well as following the trajectory of the magazine todateen, object of this study. The main contribution of this research was to demonstrate, for the focus of the information management, which the processes for which the information passes until changedding itself into knowledge, through its articles and sections, and being placed to its readers. / Mestre

The aim of this thesis is to offer a complete outline of the history of printed media in the region of Domažlice and other towns of this region from the beginning of publishing till the present with the aspects of contemporary trends.

Nitrogen-doped carbon materials such as carbon nanotubes and graphene have garnered much interest due to their abilities to behave as electrocatalysts for reactions important in energy production (e.g. oxygen reduction) and biosensing (e.g. hydrogen peroxide reduction). Electrocatalytic properties of these materials have been attributed to enhanced electron transfer ability exhibited by surface nitrogen atoms compared to typical carbon structures. Screen-printing has been widely employed in the production of low-cost carbon-based electrodes for sensors and biosensors. Here, we develop nitrogen-doped screen-printed carbon (N-SPCE) electrodes for detection of hydrogen peroxide - an important analyte in biosensing. Conductive ink was formulated in the lab from nitrogen-doped graphite that was produced using a simple urea-based soft nitriding technique. N-SPCEs exhibited electrocatalytic activity towards hydrogen peroxide reduction, while SPCEs prepared from unmodified carbon showed no ability to electrocatalytically reduce H2O2. Amperometric detection of H2O2 using N-SPCEs at an applied potential of -0.4 V (vs. Ag/AgCl) displayed a wide linear range of 20 µM to 5.3 mM, and a low limit of detection (2.4 µM). These performance characteristics compare favorably to other electrodes for H2O2 sensing and indicate that the low-cost, easy-to-prepare N-SPCEs described here are promising platforms for the development of biosensors.

Formulations for analysis of printed antenna structures are derived and compared, to determine one to implemented in SuperNEC based on the efficiency of its numerical solution in terms of memory usage and solution time. SuperNEC is a software application for computing the response of electromagnetic structures to electromagnetic fields. SuperNEC cannot be used for simulation of printed antenna structures. This is because the formulation that is implemented in SuperNEC does not account for the effect of the substrates that the radiating elements of the antenna structure are printed on, and it is also not intended for antenna structures whose radiating elements are surfaces. Two MoM (Method of Moments) formulations and a FEM (Finite Element Method)-MoM formulation are presented, together with different models for the antenna feed. The FEM-MoM formulation is selected for implementation in SuperNEC because it is argued that it is likely to be more memory efficient when compared to the MoM formulations, and also that less time is required to fill the matrices resulting from the numerical solution of the formulation. The formulation is implemented in a stand alone software application, which will be integrated into SuperNEC. Numerical results that are computed using the software application are presented to illustrate correct implementation of the formulation. The results are compared to: an exact solution, results from another publication, and results computed using a different formulation. Good agreement is obtained in each case.
