Ergonomics, the science of working rationalization, seeks the best relationship between man and his working tools. In Dentistry, ergonomics is present as for the professional working correctly seated, in functional comfort, intervening of supine position patient, by means of suitable equipment and instrument. Nowadays, dental equipment is justly rationalized; however, some instruments should take shape, in order to adapt those requirements. The hand tool design should permit a comfortable, non-slip and safe handling. Thus, anatomical details, the correct position of the operator for its use and specific characteristics of application should be taken into account. The instrument under analysis - forceps - was conceived according to these requirements along with a new alveolar tooth extraction technique, based on electromyographic and biomechanical studies. The morphology of the instrument, which makes possible a simple and natural kinetics of the operator, was obtained by changing the paradigm of the conventional cross-action instruments (whose grip is always on the arms of the tool), divesting the handle from the tool arm. This induced on anatomical conceiving of perpendicular handles to the extremity of the tool arm, resulting an efficient and effective instrument, according to indicated on its experimental phase

The article reports on research conducted with fifteen teachers and forty-five students in three high schools municipal Marília - SP, with the goal of mapping relationships between school libraries, computer labs and digital devices. The investigation is linked to the other two poles: one in the Faculty of Education, Federal University of Uberlândia and another at the French Institute of Education, in Lyon, France. Responses were obtained through questions previously formulated and recorded by scholars in an interview situation. The article initially retrieves historical projects of French in the late nineteenth century with the intention of establishing linkages with the situation in 2012, in Brazil. It then presents and comments on the graphics with data. The findings indicate the absence of organicity in relations between libraries and computer labs. Handheld devices outside of school are predominantly used to play and participate in social networking sites.

Introduction : The aging is characterized by a reduction in the effectiveness of skills, among them the loss of the flexibility. The hamstring muscles may be affected by the decreased flexibility occurs when elderly can present limitation of gait, low back problems and osteomuscular. Among the techniques used to evaluate the flexibility of the hamstring muscles are the Sit and Reach Test and Computerized Photogrammetry evaluation of the popliteal angle . However, the scientific literature doesn’t provide consistent data on the correlation of these forms of evaluation. Objective: To analyze the correlation between the sit and reach test and Computerized Photogrammetry evaluation of the popliteal angle used to assess the flexibility of the hamstring muscles in elderly women. Method: This was a cross-sectional, observational study, consisting of 39 elderly, healthy. The evaluation was composed by forms with personal details and physical examination (body weight, height and body mass index), and the evaluation of tests to measure the flexibility of the hamstring muscles (Sit and reach test and Computerized Photogrammetry evaluation of the popliteal angle). The correlation of the data was done by using the Spearmam’s rank correlation coefficient, with a significance level of 5% (p<0.05). Results: The data showed a positive correlation between Sit and Reach Test Computerized Photogrammetry and the popliteal angle of the right leg (r=0.4690, p=0.0026) and the left leg (r=0.3604, p=0.0241). Conclusion: The data from this study allow conclude that the tests for assessing hamstring flexibility in elderly women, the Sit and Reach Test and Computerized Photogrammetry evaluation of the popliteal angle are complementary because it doesn’t correlate strongly.

Este estudo foi desenvolvido a partir da atuação, como educadora-bolsista, em uma sala de aula possibilitada pelo projeto EJA/PIBID (Programa Institucional de Bolsa de Incentivo a Docência) assim, a partir da vivência junto às práticas escolares diárias e na busca de novas formas de ensinar os conteúdos escolares foi elaborado este estudo que visa refletir sobre as práticas da escrita e os sentidos que os alunos da EJA vão atribuindo a esse ato. As práticas aqui trazidas referem-se às práticas de registros escritos e da oralidade em sala de aula, que desafiam para outros olhares, principalmente por se tratar de jovens e adultos pouco ou não escolarizados. Para pensar a importância dos registros em sala de aula, que é o objeto principal deste estudo, parte-se de alguns apontamentos sobre a oralidade, na e pela oralidade; assim vai se delineando o objeto do estudo. Como referenciais teóricos foram escolhidos autores como Ana Maria de Oliveira Galvão, Anabela Brito de Freitas Mimoso, Valdemir Miotello, Elizabeth Vencio, entre outros que fazem referência à oralidade vinculada às práticas de escrever; nesses autores, busco estabelecer um espaço para a mesma aprendizagens em sala de aula. São referências também autores como João Wanderlei Geraldi e Paulo Freire que pontuam e defendem que a aprendizagem da escrita deve ser um processo com sentido para o aluno. O trabalho contempla como material de análise os registros elaborados a partir de experimentações em uma sala de educação de jovens e adultos, envolvendo a oralidade, e os registros escritos, produzidos pelo grupo, em um caderno denominado “Caderno de Registro das Aprendizagens”; nele, os registros eram feitos, ao final das aulas, pelas alunas e pelas educadorasbolsistas. O trabalho apresenta algumas considerações acerca da oralidade, reconhecendo sua presença e importância na produção da escrita na sala de aula, da sala de aula para a vida dos alunos na EJA

This is study proposes to evaluate the ergonomic aspects of dental equipments. Based on the characteristics proposed by ISO/FDI, on the existing literature and related researches an evaluating system was devised. Thirty nine dental clinics were examined using the 165 pointssystem proposed, distributed in 12 criteria. None of the dental clinics examined showed a bad ergonomics level, 41% were good and 59% reached excellent levels. The point-supported evaluation system proposed is effective in the analysis of the ergonomic conditions of dental equipments, allowing a quantification of their characteristics. Using this system, the dentist can also know the level of ergonomic satisfaction existing in his equipment, and identify the conditions to be improved. It was concluded that the equipment belonging to dental workplaces evaluated had excellent level of compliance, however corrective measures are needed since even the presence of a few non-conforming items is a sufficient condition to cause injury to users, decreased efficiency and comfort and loss quality of service

The technological advances of recent decades combined with digital inc1usion in Brazil sparked the country's population to the constant use of computers to perform tasks in many different natures. Whether it's for communication, entertainment, work or school, computers are tools with increasing numbers in Brazilian homes. Along with this evolution the Brazilian Physics teaching should be aware of the use of teaching tools that relate directly to the computer to student learning. Highlighting in this work we have scanned the contents of the Wikipedia community, a wide variety of educational videos placed on YouTube, educational games that try to teach the player in a fun way and a variety educational softwares placed on the World Wide Web. It is with special attention to educational softwares as tools for teaching physics, which describe some strategies for use of these software, combined with the textbooks, to illustrate some ways to introduce the use of educational softwares directly in the classroom
