With the growth of the demand on electric energy in the last decades, the urban distribution and transmission systems have experienced a bigger necessity to improve on the substations, the automation procedures and techniques on the operation maneuvers of such systems, in a sense that better attends the quality levels, availability, continuity and operational reliability. In this way, the objective of the present paper is to perform a study of protection and control on an electrical industrial system involving the procedures of digitizing and maneuvers automatism utilizing operational techniques and other pertinent information used in a typical high-voltage Industrial Electrical System. Analysis were made on short-circuits to specify the main components of the 138 [kV] substation, in addition, there were used digital MiCOM relays to make the protection of the present elements. With that, a program was developed to allow the user to monitor the condition of circuit-breakers through a supervision screen being able to simulate some kinds of faults, as well as observing the characteristics of each device. This way, the importance of having a fast and reliable system that ensures the equipment’s protection and the industrial process continuity due to faults on the electrical system is noticeable. It’s important to highlight that all this digitizing was mainly favored by the development of digital technology on the last years, mainly on microelectronics, also with the appearance of supervision gadgets allowing the development of complex systems in supervision and electric energy control

The ability to tridimensionally evaluate pathological and anatomical areas, in apical surgery planning, presents a number of advantages. Cone beam computed tomography (CBCT) was developed for dental applications. This paper aims to present a literature review on CBCT, highlighting its advantages over both conventional computed tomography (CT) and radiography. Moreover, its clinical applications in apical surgery are discussed. LITERATURE REVIEW AND CONCLUSION: Unlikely CT, CBCT captures a volume of data in a single 360º rotation, providing benefits such as higher accuracy, better resolution, reduced scanning time and reduced radiation dose. In the maxillofacial region, CBCT has been mainly used in the assessment of dento-alveolar pathology and oral traumatology. CBCT provides a better diagnosis and quantitative information on periodontal bone levels than conventional radiography. It has also been used for patients requiring surgical facial reconstruction, orthognathic surgery, dental implants, and more complex tooth extractions. Besides that, it seems to be a significant tool in modern endodontic practice, presenting useful applications in apical surgery.

The text is the initial result of a project called Global iTV, Interactive and systems Hybrid TV: a new advanced scheme for future services and applications in a global environment, contemplated by Call MCTI / CNPq 13/2012 – EUBrazil Cooperation Program in the field of Information and Communication Technologies (ICT) which has as its central theme the development of a standard that enables interoperability between the various digital TV systems operating jointly, exchanging and using information. Thus, using bibliographical and documentary research, the article goes on to demonstrate how this perspective panorama is drawing from the advent of digital television and the use of technology in Latin America, seeking to identify similarities, differences, problems and solutions arising from the use and consumption of digitizing television signal in the region. The results demonstrate the importance of media convergence, but point out that there are still large sections of the population on the margin of the Digital Society and the benefits provided by digital networks and that poverty and poor education are important contributions to this scenario.

In Brazil, the discussion about thereplacement of analog television signals to digitaland its impact on society, in media companies andgovernment began in the 90s. Embryonic steps towardsdigitalisation of the television signal ground were thegovernment of Fernando Collor de Mello (1990-1992),with advances during the government of FernandoHenrique Cardoso (1994-2001) and in the governmentof Luiz Inacio Lula da Silva (2002). The academy startsthe discussion in 1996. This article aims to bring to lightthe results obtained from the survey Digital television:a historical perspective , which received the supportof CNPq for funding of two scholarships for scientifi cinitiation between August 2008 and July 2009. Theproject sought to identify what has been published onthe subject in the fi eld of Social Sciences and from threemacrodescritores (information management, publicpolicy and value chain), providing the li ing of a virtualcollection Zotero bibliographic innovative platform.The mapping serves to show the growing interest anddevelopment of research in the country during theperiod - when the number jumped to three works inthe fi rst seven years (1995-2001) to 198 in the last sevenyears (2002-2008). The research sought to identify themajor authors and works related to digital televisionand published in the country. The survey took intoaccount books, articles published in books, journals,Annals of Compós and Intercom, and dissertations andtheses. Data and refl ections on the survey are containedin this communication.

The understanding of the geo-morphological characteristics allows the identification of flood areas and instability slopes among others important features for land use planning. The study of the hydrological net and the analysis of morphometric parameters help in the geomorphologic characterization, providing specific physics indicators that quantify the risks for environmental damages. The present work used Geographic Information Systems (GIS) and carried out the morphometric analysis of two watersheds in the Alto Rio Sorocaba, municipality of Ibiuna (SP). Using digitalized topographic bases in the scale 1:50,000, the main morphometric parameters were extracted and the Digital Elevation Model (DEM) was obtained. Hence the slope, ground illumination, hill orientation and relief feature maps were elaborated. The characteristics for the two watersheds were quite similar, both have low risks for floods and landslides. Therefore, the concave feature is the predominant hill shape for both watersheds. The morphometric parameters directly related to the river density of the watersheds showed some differences, because the Sorocabuçú watershed presents higher value, resulting in a higher level of relief development. Thus, with this characterization it is possible to provide subsidies for environmental planning actions to the area.

The Digital Age, with its new interactive and converging technologies, stimulates original forms of sociability, which are interconnected, intercommunicating and virtualized through hyperscreens. Another kind of interaction arises from the digitization and new speeds of contemporary communicative process. With the new order of knowledge, it is now possible to transgress the limits of physical space and linear time sequence, through the collective development of content through such telematics networks. Youth gives voice to a new type of user, or a social actor, whose thinking is connected to other communication habits, consolidating singular cultural standards, demanding new languages and skills. Here, we address the nature of this Design of new relations, interactions, behaviors and social systems that emerge in the so called Information Society.

O rádio é o veículo de comunicação que as pessoas mais usam para receber informação e entretenimento diário. A portabilidade, a proximidade das emissoras com seus públicos e os receptores de baixo preço sustentam há várias décadas, a popularidade radiofônica. Mais recentemente, o rádio se beneficiou do crescimento da frota automotora e da enorme quantidade de celulares, que embutem gratuitamente receptores de rádio. Uma pesquisa realizada em 2010, pelo GPR (Grupos dos Profissionais do Rádio) sobre consumo radiofônico pelos brasileiros, apontou que 74% deles ouvem Rádio em receptores tradicionais, 63% ouvem pela internet, 61% pelo rádio do carro, 37% sintoniza rádio pelo celular, 21% por meio de dispositivos como MP3, MP4 e iPhone; 12% por meio de canais de áudio da TV a cabo e 3% via internet do celular. A pesquisa GPR apresenta números significativos de ouvintes em cada modalidade de dispositivo para recepção radiofônica. São indicadores claros de que um mesmo ouvinte está sintonizando regularmente suas emissoras prediletas em mais de um tipo de receptor de rádio. A nova variável demonstra que a digitalização da produção, da transmissão e da recepção, além de transformar o rádio em um veículo com linguagem multimídia, também lhe agregou a possibilidade de multi-sintonia. Ou seja, as mensagens radiofônicas passaram a ser recebidas pelos ouvintes em diversos terminais, todos dotados de ferramentas multimídia e de recursos para interatividade. É a evidência de que o rádio ingressou definitivamente no território binário e convergente do ciberespaço. De agora em diante, a formação das várias carreiras profissionais para a produção radiofônica terão que atentar para as transformações do veículo na era digital.
