The objective of this study is to evaluate the measurement accuracy of endodontic files obtained by digital and conventional radiographies in primary teeth. Kerr and Hedströen files (# 20), with the reference as the apparent length of tooth, were inserted in the root canal of 18 extracted primary teeth, which were x-rayed by digital and conventional techniques. Measurements from a reference point to the apical end were carried out by an experienced operator twice in a week. An electronic ruler was used for the digital method and a caliper was used for the conventional method. The data were subjected to Pearson correlation test and Student´s t test (p = 0.05). The correlation between the first and the second measurements was r = 0.99, regardless the type of file and method. Comparing the measurements within the methods, the agreement was r = 0.96 for Kerr and r = 0.95 for Hedströen files. The values of length files in the digital radiographies were statistically lower than that obtained in the conventional radiographies (p = 0.02). However, the values obtained by the two methods were statistically similar to real length of teeth for Kerr files (p = 0.29) and for Hedströen files (p = 0.18). The digital radiography was a more trustful method to obtain the lengths of endodontic files.

One of the areas of human identification is Cheiloscopy, the name given to the study of the lips, their characteristics (such as thickness, position of the grooves and grooves) and the record of the impressions left by them. There are variations in the layout of the lines and fissures of the lips, which are unique to each individual, permanent and unchanging. The lip print rarely changes, enduring minor traumas such as inflammation or sores. In criminal investigations, lip prints, visible through the presence of lipstick, can be found on glasses, napkins, clothes, cigarettes, indicating a relationship between the subject and the scene of the crime. Latent impressions may be revealed employing specific chemicals such as powder of silver and aluminum nitrate. Although it is not a very common method, Cheiloscopy may become very useful in forensics due to the extensive amount of valuable information that it brings. The objective of this study was to review the literature on the use of Cheiloscopy in human identification, using traditional and digital methods. It was found that the literature is still in need of studies in this area. The advent of new digital technologies can facilitate the implementation of technical expertise, generating speed and objectivity. New research studies are necessary, especially in the development of digital methods. The application of Cheiloscopy can greatlyhelp with Law, in the identification of living suspects and dead individuals. In the end the benefit will fall to society as a whole.

Objective: The aim of this study was to develop an educational oral health digital game for 5-to-7-year-old children. Method: The game, called “Dr. Trata Dente”, was based on the approach to three different oral health-related topics: a) bacterial plaque and the main diseases caused by it; b) oral hygiene methods for bacterial plaque control; c) dental caries and preventive measures for this disease. These topics were discussed in sequential order in three different stages of the game. Dr. Trata Dente is represented by the figure of a little super-hero dentist, who talks to the children about oral health during the game. The game is sub-divided according to its propositions to the children, into an association game, a memory game and a coloring game. After its development, the game was evaluated by three professionals of each of the following areas: Dentistry, Pedagogy and Psychology (n=9), who verified the suitability of the concepts presented in the game as regards oral health, linguistic abilities worked with the children, fulfillment of the intended didactic criteria, and the playful aspect of the game. Results: According to the dentists, the dental concepts presented in the game are adequate. According to the pedagogues, the choice of a super-hero was correct and the given explanations are well elaborated, organized and have accessible language, although long. For the psychologists, the game has a potential positive effect on the children’s learning, but there should be more interaction of the character with the children. After this evaluation, changes were made in the game according to the professionals’ suggestions. Conclusion: It was concluded that in spite of the suggested alterations, the game is suitable for teaching oral health by means of children’s play.

This paper proposes a model of educative content structuring for interactive digital television programs. Its intent was to provide references for collaborative production processes and content organization in learning networks associated with university and educative television broadcasting services. The model defines terms, actors, events, environments, as well as content categories, classes and attributes, indicating criteria for their synchronic or asynchronic association in a dynamic television schedule. The model is presented in both descriptive and visual formats, with the use of conceptual maps. The results indicate that interactive use of digital television in education requires systematic content models covering communitarian participation in both media production and distribution processes, in order to enhance learning instruments beyond vertical, hierarchical and centralized communication sustained by traditional broadcast channels.

Este artigo trata de uma pesquisa exploratória, de cunho bibliográfico, com o objetivo de estabelecer relações entre os conceitos de Telejornalismo Regional em TV Digital (TVD) com o gênero do Infotretenimento, definido como o modelo de programa que adota a fórmula de uma produção híbrida, seguindo uma linha que se situa entre informação e entretenimento. Considerando-se que, do ponto de vista do produtor de conteúdos comunicacionais, a “Era da Digitalização” requer um aperfeiçoamento e uma devida utilização dos recursos disponibilizados pela TVD, o artigo torna-se relevante, pois abre o caminho para se pensar numa programação para a TVD, antes mesmo de sua efetiva possibilidade de produção e programação. Pretende-se com este artigo pesquisar as ferramentas necessárias que justifiquem a possibilidade de um telejornal regional interativo atrair o seu público-alvo para as informações noticiadas por esse veículo.

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.
