A Construção do Conhecimento na Atualidade: Um Olhar Sobre o Impacto da Tecnologia

In the paper analyzes the process of knowledge construction in the news regarding the emergence of massive information and communication technologies. In this context, through a qualitative approach, first we examine the potential of production, dissemination, access and use information in a technocratic perspective, and secondly, the negative impacts stemming from the computed mediation, mainly linked to the complexity of policies of democratization of access to information and loss of criticality of science. The focus of this review focuses on the current model of information search and knowledge construction through the Web, outlining aspects inherent to the process in general. Similarly, envision different contributions of information science for the systematization of human knowledge, guided through the social actions of professionals working in various fields, with emphasis on the information representation and retrieval. It is hoped that work can contribute to the current thematic reflection on the production, dissemination and use of information as well as on digital inclusion policies.

Web Service para geração de VRS no contexto de posicionamento GPS

Internet is fully inserted in contemporary society, specially in relation to entertainment services and trading. Its reach has transposed the traditional desktop computer models coming to mobile devices like cell phones and GPS receivers. Likewise, the scientific community takes its benefits, both for publication of studies and for communication between clusters processing information, such as at LHC, located in Switzerland. Concerning geodetic positioning, researches in the area present the concept of Virtual Reference Stations - VRS, in which is necessary a communication way between the real reference stations and a central system as well as between central system and a service requester. In this work, we analyze the current solutions for generation of VRS with regard to data delivery for the service requester and present a solution based on Web Services as an alternative to the model being developed by Spatial Geodesy Study Group – GEGE/FCT/UNESP. Comparing solutions, it was verified the potential of Web Services to aid in researches of geodetic positioning using VRS. Using such technology, it is obtained interoperability, providing greater flexibility to develop client applications, both development carried out by researchers of the university or by any person or enterprise wishing to use the service

WSPControl: aplicação distribuída baseada em Web Services para monitoramento remoto de computadores

The tool proposed, known as WSPControl, enables remote monitoring of computers across the Internet using distributed applications. Through a Web Services architecture is possible the communication between these distributed applications across heterogeneous platforms, also eliminates the need for additional settings in computer networks, such as release of ports or proxy. The tool is divided into three modules, namely: • Client Interface: developed in C Sharp, is responsible for capturing data on performance of the monitored computer also connects to the Web Services to report this data. • Web Services Interface: developed in PHP using the PHP SOAP library, is responsible for facilitating the communication between internet applications and client. • Internet Interface: developed in PHP, is responsible for reading and interpreting the information captured these available on the Internet

Websislapam: sistema de avaliações de pessoas baseado em tecnologias WEB

This work, entitled Websislapam: People Rating System Based on Web Technologies, allows the creation of questionnaires, and the organization of entities and people who participate in evaluations. Entities collect data from people with the help of resources that reduce typing mistakes. The Websislapam maintains a database and provides graphical reporting, which enable the analysis of those tested. Developed using Web technologies such as PHP, Javascript, CSS, and others. Developed with the paradigm of object-oriented programming and the MySQL DBMS. For the theoretical basis, research in the areas of System Database, Web Technologies and Web Engineering were performed. It was determined the evaluation process, systems and Web-based applications, Web and System Engineering Database. Technologies applied in the implementation of Websislapam been described. In a separate chapter presented the main features and artifacts used in the development of Websislapam. A case study demonstrates the practical use of the system

Classificação de workflows baseados em web services

Over the last decades changes have occurred in communication within and between enterprises, made easier by technologies suchas E-commerce, Internet, ERP systems and remote meetings and there was a rapid progress in network technology, which has changed the way business is done. A standardized way to offer services over the internet is using web services. Web services are a kind of remote procedure call and are generally used to integrate systems, independent of language, both client and server. It is common to use several web services run in sequence to perform a business process. To this type of process, gives the name of workflow. Thus, Web services are the primary components of workflows. A tool that provides a way of visualizing the behavior of a workflow can assist the administrator and is required. The present work presents the development of a tool that allows the administrator to classify visually services components and evaluate their importance in the final performance of a workflow. As proof of concept we used several virtual servers and computers where each computer has received a set of web services. A proxy was added between each call of workflows collecting relevant information and storing them in a database for later analysis. The analysis was based on Quality of Service parameters

Web Services Aplicados à Visualização

With the rapid growth of the use of Web applications in various fields of knowledge, the term Web service enter into evidence in the current scenario, which refers to services from different origins and purpose, offered through local networks and also available in some cases, on the Internet. The architecture of this type of application offers data processing on server side thereby, running applications and complex and slow processes is very interesting, which is the case with most algorithms involving visualization. The VTK is a library intended for visualization, and features a large variety of methods and algorithms for this purpose, but with a graphics engine that requires processing capacity. The union of these two resources can bring interesting results and contribute for performance improvements in the VTK library. This study is discussed in this project, through testing and communication overhead analysis

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.
