TEAMWORK COMMUNICATIVE SKILLS AND ABILITIES FORMATION IN TRAINING OF ENGINEERS FOR THE FUTURE
This paper reveals training experience of engineers for the global companies. It is shown that foreign language skills in modern conditions turn into the significant personal and professional characteristic of a specialist. Language training gives grounds to communicative skills formation, including bilingual communication. For modern engineers a foreign language becomes an orientation tool in information space and also a professional problem solving tool in bilingual communication. An integration of language modules into the curriculum is a distinguished feature of the given training system. Thus the principle of gradual problem solving skills broadening becomes a reality. Various interactive training courses and virtual training modules are used during this training. Such approach erases speech barriers, develops ability to communicate in a foreign language and also ability to work in team. Â Index Terms – training experience of engineers, professional characteristic of a specialist, language training, integration of language modules into the curriculum.

AN EMPIRICAL STUDY OF THE BEHAVIOR OF A FACE RECOGNITION SYSTEM BASED ON EIGENFACES AND K-NEAREST NEIGHBORS TECHNIQUES
Developing a face recognition computational model is a hard task. Extracting facial features from facial images becomes a hard when the images have different dimensions, especially in the steps of extraction and classification. In this paper, we propose an empirical study of optimization on the rate accuracy results from a facial recognition based on Eigenfaces and K-Nearest Neighbors techniques. It was investigated the following topics: images with three different dimensions, number of features (Eigenfaces), k values from K-Nearest Neighbors technique and three distance measures. Addressing the problems of image dimensionality for facial recognition, understanding which parameters are more relevant from the addressed techniques in order to enhance the accuracies rate of facial recognition were the goals of this study. Following this, it was proved from the experiments that images with 12x9 sizes produce the best facial recognition accuracies rate, using the normalized Euclidean distance and a number of Eigenfaces equals to twenty.

ALGORITMO DE RECONHECIMENTO DE VOZ PARA A INSERÇÃO EM SISTEMAS EMBARCADOS
The speech recognition technology is beenincreasingly used in electronic systems and devices, in severalapplications. This mainly occurs due to advances intechnology such as digital signal processing, microprocessorsand the appearance of recognition algorithms more and moreeffective. This paper presents a recognition system of voicecommands to drive a DC motor, whose algorithm wasdeveloped in MATLAB and tested in SIMULINK environment.The algorithm analyzes the speech signal characteristicscompared to the reference signals by cross-correlationbetween them, to determine which command was performed.The developed system has only two commands: "activateengine" that results in a logic 1 used to drive the motor, and"end" that results in a logic level 0 to turn off the engine, bySIMULINK. Although simple, the system achieved a good setof performance. Â Â Index Terms - Cross-correlation, speech recognition,trigger engine.
AÇÃO INTERDISCIPLINAR EM CURSOS DE GRADUAÇÃO EAD PARA UMA FORMAÇÃO INTEGRAL DOS ESTUDANTES E PARTICIPAÇÃO NO ENADE - EXAME NACIONAL DE DESEMPENHO ESTUDANTIL
This paper presents an interdisciplinary action taken in distance education undergraduate courses at Southern Cross Educational aiming the integral formation of the students and their participation in institutional assessment processes such as ENADE – National Examination of Student Performance. In this action participated different areas of courses, in order to work out a common core of knowledge, covering topics of current affairs and general knowledge required in the institutional evaluation process ENADE. To do it we used the AVA Blackboard as a tool to measure, quantify and analyze the results of proposed questions. The results obtained allowed the identification of lights and shadows in relation to approach these issues in each of the Distance Education Undergraduate Courses and apply strategies for a more complete learning and an integral formation of the student, preparing it for a better academic and professional performance. Â Â Index Terms - Institutional Evaluation Process, Virtual Learning Environment, Interdisciplinarity.
NORMAS DE ENGENHARIA E SEGURANÇA DO TRABALHO: PROTEÇÃO DO TRABALHADOR E RESPONSABILIDADE SOCIAL DA EMPRESA
The Brazilian Constitution requires from the employer the duty to promote the reduction of all the risks that affect employee´s health in the workplace (physical, chemical, biological, psychological etc.). The simple violation of any of the legal or regulatory provisions which establish the employer duties regarding safety, hygiene, occupational health and the work environment, creates the presumption of employer's guilt by the accident occurred, when there is injury with causation. Besides the fulfillment of the engineering and safety standards, for protection and reduction of the risk of accidents, it is necessary to train employees to use the Personal Protective Equipment, as well as require and enforce the use of them, including under penalty of dismissal for serious misconduct of the employee who refuses to do it. Compliance with engineering and safety standards is vital to the health of the employee, as well of the company. Â Â Index terms - rules of engineering and work safety, social responsibility, worker safety.
MATRIZ DE DECISÃO DAS TECNOLOGIAS DIGITAIS NA EDUCAÇÃO (TDE): PLANEJANDO UMA AULA TECNOPEDAGÓGICA
he aim of this study is to present a practical application of DTE Matrix (Digital Technology in Education) in planning a lesson with inclusion of digital materials. The matrix works with educators in selecting the most suitable tool for each educational activity through the organization of information about Digital Technologies (DT) available, thus teachers can meet and examine individual tools and determine whether they can actually fit the educational needs, previously planned. The main purpose is to help to compare DT in a quickly way and share their findings with the staff in order to make the pedagogical actions easier. The methodological design of this study is based on a theoretical and practical-descriptive approach. The matrix will help the optimization and improvement of DT in education and to know the factors that must be considered, such as: accessibility, technical and educational requirements, level of knowledge and connectivity. Â Â Index Terms - Decision Matrix, Digital Technology, Taxonomy.
QUALIFICAÇÃO PROFISSIONAL PARA PROFESSORES DAS ÃREAS TECNOLÓGICAS SEGUNDO O MODELO DA COMPLEXIDADE
This paper presents both, a theoretical and practical vision in Education. By one side, it enhances guidelines of “Complex Thoughtâ€ theory applied to Technological Education. By the other side, it enhances a practical view under the author pedagogic experience at UFSC University, Florianopolis, Brazil. This practice has open new perspectives looking for technological education aggregating some important elements to be included in curriculum development. This proposal points out the importance of integration of the different educational parameters. It considers traditional educational parameters living together with new ones. They, all together, will follow the integration principle applied to pedagogy. Conclusion enhances the Complex Approach perspective is in accordance with the international demands in terms of technological courses development.

USO DE PROGRAMAS DE SIMULACION DE CIRCUITOS PARA EL ESTUDIO DE POTENCIA EN SISTEMAS ELECTRICOS
This work present some examples of electric circuit simulations to study the electric power delivered to consumers. There are various electric power theories which give definitions about the different power components that an electric load can consume. The reason is because some components must be limited; it is preferable deliver only active electric power ideally with the rest components in zero. To determine the different power components is necessary to measure over the electric load; however, when the electric load model is kneed, these components can be obtained using simulation programs. It will present the examples in detail and will show how electric loads can be classified from the point of view of the electric power delivered. It will analyze the convenience to use these simulation examples in electric circuits and power electronics courses. Â Â Index Terms - ATP, Electric Power, Simulation program.
