A sociedade atual vive desde a década de 50 uma “revolução psicofarmacológica”, em que os avanços tecnológicos da psiquiatria e da neurologia possibilitam a criação de dispositivos que conseguem ter uma melhor visualização do funcionamento físico-químico do cérebro, onde o paradigma de tratamento de sofrimento psíquico passou a ser baseado na utilização de psicotrópicos. Dessa forma, a medicina buscou tratar neurocientificamente comportamentos desviantes da norma social. Nesse cenário, o diagnóstico do Transtorno de Déficit de Atenção e Hiperatividade (TDAH) desponta com certa freqüência e com uma constância ainda maior o uso de Ritalina, nome comercial do metilfenidato, no tratamento do suposto transtorno, principalmente em crianças. Esse presente trabalho faz uma reflexão, a partir de uma revisão bibliográfica, a cerca do aumento do consumo de Ritalina nos últimos anos, procurando problematizar a forma indiscriminada de diagnosticar e tratar o TDAH.

Post-Occupancy Evaluation of buildings considers user satisfaction, building pathologies and performance, as well as users interventions in the built environment. The possibility of identifying interventions regardless of the user could provide a significant gain in the efficiency of Post-Occupancy Evaluations. We foresee the application of Augmented Reality (AR) to improve the identification of renovations by overlapping the construction information model with an image of the actual building. This article validates the use of AR on existing smartphone and tablet applications. This study proposes the incorporation of AR into the planning, execution and application of Post-Occupancy Evaluation. For the planning, this study proposes the development of a new research tool. With regards to the execution, this study examined the data collection conditions on site through the visualization of overlapping models. For the application, this study proposes displaying the results through the use of RA information layers. The transparency oft he RA model was used to allow comparison between the virtual model and the real model. The development and adaptation of the virtual model and the solution developed for the experiment of the RA proposal are presented and discussed. The experiment points to shortcomings that still make the proposed technological solution unfeasible.

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.

A laparoscopia ainda é pouco utilizada como ferramenta para técnicas de reprodução assistida em cervídeos sul-americanos, não havendo informações sobre seus efeitos e protocolos anestésicos seguros para sua realização. Objetivaramse avaliar as possíveis alterações na freqüência cardíaca (FC), respiratória (FR), saturação de oxihemoglobina (SpO2) e temperatura retal (TR) durante a laparoscopia para visualização dos órgãos reprodutivos de seis fêmeas de veado-catingueiro (Mazama gouazoubira) anestesiadas com a associação cetamina (5mg/kg), xilazina (0,3mg/kg), midazolam (0,5mg/kg) e isofluorano. Cada animal, após anestesiado, foi posicionado em decúbito dorsal para realização de duas laparoscopias com insuflação abdominal de CO2 (14,2 ± 2,39mmHg; M ± EPM) com intervalo de 40 dias. Para avaliar os principais eventos da laparoscopia, esta foi dividida em três períodos: animal sem insuflação abdominal (P1), com insuflação abdominal (P2) e insuflação abdominal com os quadris elevados a 45º (P3). O controle foi realizado após 40 dias da última laparoscopia, para isto, cada animal foi novamente anestesiado e mantido em decúbito dorsal por um período de tempo igual ao tempo médio de duração das anestesias realizadas nas laparoscopias, sem que o procedimento laparoscópico fosse realizado. O tempo de anestesia dos controles foi também dividido em P1, P2 e P3, respeitando o tempo médio de duração de cada um destes períodos das laparoscopias. Para análise dos dados foi usado o teste de análise de variância (ANOVA) seguido do teste de Tukey e valores de P<0,05 considerados significativos. Não houve diferença significativa nos parâmetros estudados em nenhum dos períodos estabelecidos para o controle e laparoscopia. Porém, a FR média entre P1 (38,8 ± 4,42) e P3 (32,7 ± 4,81) e a TR média entre P1 (38,2ºC ± 0,17), P2 (37,6ºC ± 0,19) e P3 (37,0ºC ± 0,21) variaram significativamente, independente da laparoscopia. Tais dados permitiram concluir que a laparoscopia não promoveu alterações significativas nos parâmetros avaliados, embora o protocolo anestésico utilizado tenha contribuído para redução da temperatura retal resultando em risco de hipotermia durante a anestesia.

The objective of this work was to develop a methodology for seed processing and X-ray analysis and to study imbibition pattern in seeds of candeia (Eremanthus incanus). Seeds were gathered in 2001 and 2002 in Morro do Pilar and Lavras respectively, processed and stored in a cold chamber (5ºC/60%RH) until the start of experiments. In order to identify unfilled seeds, a protocol was developed for X-ray use combining radiation energy (Kv) and exposure time (seconds). For elimination of unfilled seeds, an experiment was conducted using a South Dakota seed blower whereby different opening settings and ventilation times were combined. Original seed lots and categorized lots following radiograph viewing were tested by germination tests, with seeds being cleansed in sodium hypochlorite and scattered over blotting paper in 'gerboxes' and then taken to germinators with alternating temperatures of 20º-30ºC and 10 hours of light, for up to 15 days. Imbibition curves were determined under the conditions 30ºC, 20º-30ºC/10 hours of light and 30º-20ºC/10 hours of light. The X-ray protocol that best allowed viewing of internal seed structures was 30Kv for 45 seconds. Seed separation using the blower setting at a 3.0 opening for 30 seconds raised the number of embryonic seeds to values exceeding 99%, also raising the germination rates as a consequence. The imbibition pattern is three-phased and the germination process is completed in 72 hours. Under alternate temperatures, primary root growth is favored.

The fierce competitiveness of the current market and the sophistication of customer requirements made the commitment to quality a need within organizations. The search for quality has been carried out by the adoption of quality management systems, a formal organization that should be present throughout the organization, from the initial identification of market needs to the satisfaction of customer requirements. The methodology most commonly used for this purpose is based on the requirements of ISO 9001, latest version of 2008. Considering this scenario, was developed a case study in a small company of the industrial sector with the development of a plan for the implementation of ISO 9001. The proposed methodology involved the construction of a theoretical framework on the subject and the development of a case study with a qualitative approach. Initially, was applied a questionnaire to the representative of the organization about the company's operating procedures, activity logs held, current documentation, planning and resource management for the construction of an assessment about the adequacy of the company needs to ISO 9001. Were obtained as results the characterization of production processes and organizational structure of the company and examples of policy and objectives of quality, performance indicators, document control, system for visualization of non-compliances, among others. Finally, the benefits of adopting a quality management system based on ISO 9001 requirements for the company and its environmental issues such as increased process efficiency, less waste and greater profitability, were pointed out, and the conditions for effective certification in the future
