A-Nperp, Pg-Nperp e mandibular plane). Thirty patients (male or female), with age varying from 19 to 48 years old were analyzed. All patients were diagnosted with mandibular retrognathism and submitted to bilateral sagital mandibular advancement. All tracings were performed in lateral cephalometric radiographs obtained one week before surgery. The intraclass correlation coefficient analysis (ICC), the t test adjusted for Tukey-Kramer test and Schuirmann test were applied. The results showed that the manual tracings and Nemotec® tracing had excellent reliabilities for all measures (ICC > 0.98). The Dolphin Imaging® showed low reliability in anterior facial height (value of ICC = 0.70), Co-A (value of ICC = 0.47) and Co-Gn (ICC value = 0.49). In A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB there were no differences between the 3 tracings (p > 0.05), for the anterior facial height measures differences were found between the Dolphin Imaging® and Nemotec® tracings, but no differences were observed as compared to the manual tracing (p > 0.05), in Co-A and Co-Gn measures t Dolphin Imaging® presented a significantly lower mean than the other methods (p > 0.05). The manual tracings were equivalent in 6 of 8 measures (A-Nperp, Pg-Nperp, md Plan, SNA, SNB and Co-A), there was no equivalence between the methods in the anterior facial height and Co-Gn measures (p < 0.01). The Dolphin Imaging® method was not equivalent in any of the 8 measures. It was concluded that in the manual tracing only the Co- Gn, Pg-Nperp and SNB measures confirmed the diagnosis of mandibular retrognathism, and the Nemotec® software showed better results than the Dolphin Imaging® software.

A presente reflexão motiva-se no seio da crescente discussão sobre a utilização das tecnologias de informação e comunicação na educação, assim como acerca do uso de computadores que permitem o acesso à pesquisa e a informações novas. Este trabalho é decorrência de estudos realizados para a disciplina de monografia de conclusão de curso, e tem como objetivos: verificar o posicionamento de professores sobre o uso do computador como um recurso que estimule a leitura para alunos dos Anos Iniciais do Ensino Fundamental; averiguar o que os professores pensam sobre a inclusão digital; descobrir para qual tipo de leitura o computador é utilizado. Os resultados apresentados são provenientes apenas dos estudos teóricos realizados, visto que fazem parte de um projeto de pesquisa ainda em andamento.

The objective of this paper is show the development of an Eletronic Control Unit (ECU) for Baja-SAE vehicles from its requirements to final implementation. An ECU for Baja-SAE vehicles is made of electric and electronic circuits (appropriated to the hostile situations of an off-road competition) able to make important measurements for the running or stand-by vehicle performance. For this development, some concepts were studied: embedded electronics concepts (mainly microcontrollers and data acquisition circuits) and sensoring. Both the studies were made considering the off-road environment. After these initial studies, the elaboration of the basics hardware and software (under simulations) has begun, and this elaboration objectives maximum performance and low implementation cost. After the theorical studies, basic definition of the hardware and software’s architectures and simulations, the printed circuit boards (PCB) were made, as exhaustive tests in these boards for debugging and verify if the boards work well. Once the system was tested in the university, it ran into a regional Southeast competition in 2010, that definitely proved the efficiency of the whole system

Automatic video surveillance system has been a frequent topic of research due to the large number of promising applications. In this research, we developed a tracking and counting people system, as well as suspicious activities detector. The model tracks individual objects as they pass through the field of vision of the camera using vision algorithms to classify the activities of each person, and according to this features, detect dangerous situations. This dissertation includes a review of several techniques trying to develop a robust and low computacional costs system to be used in glass door barrier turnstiles avoiding fraud
