We are here to expose the record of the participation of the Ituiutaba campus of the Federal Institute of Triangulo Mineiro (IFTM) in science and technology fairs. At these events, students have the opportunity to be in close contact with other researchers of similar age who are facing similar problems and with the same aspiration: learning through research. The inclusion of students in research development projects shows that teaching is not, and cannot be, disconnected from research, as both complement each other. Teaching combined with research contributes to meaningful and contextualized learning, thus enhancing teaching and learning practice. Such teaching practices, when combined with research activities, provide a differentiated look at education, ie, transform the understanding of the way of educating. Through a historical redemption of event annals, teachers’ personal records and online media news, we report here the trajectory of IFTM campus Ituiutaba and its performances in science fairs, dissemination of research project results, as well as awards and awards. acknowledgments received. Additionally, we have developed an interactive timeline that is available online at <http://bit.ly/linha-do-IFTM> with photos, videos and more information about this trajectory of our campus by science and technology fairs in Brazil and abroad.

This article presents a scientific research aiming the development of a natural interface for the control of robotic structures. The purpose of this interface is to be used as a tool for the social integration of people with special needs. On studies we used (a) a body motion sensor; (b) an arm robot mechanical structure; and (c) a software for communication between the motion sensor and the robot arm. Experiments were performed to verify the effectiveness of this interface, to identify possible failures, and implement improvements. The main results indicated that the interface works satisfactorily.

This paper presents the Internet’s contribution to the management and constructing knowledge in the last 20 years. Subsequently, we discuss how private companies, specifically Google, has determined the way people have access to the vast amount of information available online. The invasion of privacy and providing personalized results according to the profile of each person are also dealed in this work as well the risks of this. Finally, we propose some methods to ensure that individuals do not remain trapped in a cycle of repeated information and thus have access to content that would not be before your virtual reach.

As a result of discussions about studies on Science, Technology and Society (STS) we identified a need to know how to discuss these issues in a discipline of mobile programming. The purpose of this article is to show how we can introduce relevant matters to society’s problems in a highly technical approach to discipline. Thus this work has an informative approach and becomes a possible grant to aid the teachers who want to establish STS discussions in your mobile programming classes. Suggestions documented here characterized as resources for a likely improvement of critical thinking and civic conduct of students and for the promotion of discussion and reflection among teachers and future professionals on the current reality, allowing for imminent educational changes.

Energy is an important factor of economic growth and is critical to the stability of a nation. Charcoal is a renewable energy resource and is a fundamental input to the development of the Brazilian forest-based industry. The objective of this study is to provide a prognosis of the charcoal price series for the year 2007 by using Artificial Neural Networks. A feedforward multilayer perceptron ANN was used, the results of which are close to reality. The main findings are that: real prices of charcoal dropped between 1975 and 2000 and rose from the early 21st century; the ANN with two hidden layers was the architecture making the best prediction; the most effective learning rate was 0.99 and 600 cycles, representing the most satisfactory and accurate ANN training. Prediction using ANN was found to be more accurate when compared by the mean squared error to other studies modeling charcoal price series in Minas Gerais state.

In spite of exist a series of standards about software quality, besides them do not be specific for the agricultural domain, they little approachs the involved people’s influence and the organization. In function of that, the objective of this exploratory study was to investigate the possible relationships between the profile of the programmers of agricultural software and the agreement degree with sub-characteristics of the standard ISO 9126, adapted for the domain. The sample was composed by 30 programmers that answered to 15 statements regarding that standard, as well as information of demographic and social character, and information on their bond with the company. For treatment of the data, two statistical multivariated techniques were used: correlation, and factorial analysis. The results of the correlations allowed to conclude that the programmers approaches quality with a tendency to value what can be noticed quickly by the final user; the factorial analysis results allowed the reduction of the variables in five factors and the factor “attendance and clarity” was what more included correlations and it demonstrated that the variables that form it are more affected for the demographic and social data.
