Sistema atende mulher: sistema de informação no centro de referência da mulher Ednalva Bezerra

The physical, psychological, sexual, moral and patrimonial violence affects women of different ages, social classes, ethnic and racial groups, levels of education and religion, all over Brazil. One of the obstacles in the strategies of prevention and facing violence against women, in public care services, focuses on the absence of an information system, automation of data and care flows. The existence of reliable data is essential for performing diagnoses, goals and conducting research on women in situations of violence who access the service agencies. In this sense, the goal of research is to present the experience of implementing a policy of data management called Woman System, in Ednalva Bezerra Women's Reference Center, which offers host/psychological and social care, guidance and legal referral for women that face any violence situation. As methodological paths, we adopt research in action. In our analyzes, we found that in this kind of public service, the use of the data system may improve the full and humanized care to women in situations of violence. Thus, the System Woman Care, still a developing phase, appears to improve the flow of relevant information within the institution, driving a process of knowledge, decision-making and intervention against gender violence.

Implantes dentais curtos: alternativa conservadora na reabilitação bucal

The short dental implants represent an option of previsible treatment, its main indication lives in the possibility of avoiding techniques surgical invasive. The literature in the display that the geometry of the implants is of vital importance, combined with wide diameters and surface treatment, mainly when the bone quality is unfavorable. The mechanical resistance can be enlarged, increasing the number of implants and being used the spliting among them. A rigorous protocol prosthodontist should be following with intention of to avoid oblique loads and to control habits parafuncionais. We aimed at to discuss, through a wide bibliographical revision the short dental implants, their characteristics and indications, giving emphasis to the aspects biomechanic of the same ones. Material and Method: The bases given: Pubmed, ISI and Dentistry Oral Science from 1990 to 2009, were consulted to identify researches related to the length of the dental implants, with emphasis to the considered short and the biomechanics related to the same ones. They were located 568 articles, being selected 69 that gathered the inclusion criteria. Result: Among these 69 selected, 26 articles agreed the evidence level. Conclusion: Inside of the limits of appraised data, it can be concluded that the short implants represent a good treatment alternative, especially for cases with reduced bone bed. However a rigorous indication protocol and use should be followed for warranty of the success of the treatment.

Implantes curtos do tipo cone-Morse: proporção coroa-implante

The purpose of this study was to analyze the biomechanical interactions in bone tissue between short implants and implant-supported crowns with different heights. Two models were made using the programs InVesalius 3.0, Rhinoceros 4.0 and Solidworks 2010. The models were established from a bone block with the short implant (3.75 x 8.5 mm) with geometry Morse taper connection (MT). The height of the crown (cemented) was set at 10.0 mm and 15.00 mm. The models were processed by programs and 10 NEiNastran Femap 10.0. The force applied was 200N (vertical) and 100N (oblique). The results were plotted on maps Voltage Maximum Principal. Statistical analysis was performed using ANOVA. The results showed that the increase in crown height, increased stress concentration in the crown of 15 mm under oblique loading (p <0.001), the oblique loading has significantly expanded the area of stress concentration (p <0.001). Conclusion:the increase of the crown increased the stress concentration, being statistically significant for short implants Morse taper. The mesial and distal region had the highest concentration of stresses under oblique loading. The oblique loading was more harmful when compared with axial loading, being statistically significant.

Reabilitação protética de mandíbula atrófica por meio de implantes curtos: relato de caso clínico com oito anos de acompanhamento

This case report shows how the prognosis of severe mandibular atrophy can be improved with the use of short dental implants. A Caucasian 54 years-old male patient received four dental implants in the anterior mandibular region. Four months later, the definitive prosthesis was delivered. At the 8-year follow-up period, no complaints or loss of integration were reported. Short dental implants with complete, fixed definitive prosthesis can be a successful treatment in the mandibular arch.

Implementação do algoritmo de treinamento do classificador floresta de caminhos ótimos em GPU

Técnicas de reconhecimento de padrões tem como principal objetivo classificar um conjunto de amostras, sendo o processo de aprendizado a fase de maior consumo de tempo. O problema pode piorar em ferramentas de classificação interativas, o que pode ser inaceitável para grandes bases de dados. Um exemplo de classificador é o baseado em Floresta de Caminhos Ótimos [8] - OPF. Dado que muitos trabalhos tem sido orientados à implementação de algoritmos de reconhecimento de padrões em ambiente General Purpose Graphics Processing Unit - GPGPU, o presente estudo objetivou a implementação da etapa de treinamento do classificador Floresta de Caminhos Ótimos em CUDA, visando aumentar a sua eficiência. A otimização do classificador em CUDA demonstrou uma fase de treinamento mais rápida que a versão original.

Balanço de energia de fluxo de CO2: cerrado da floresta estadual de Assis

Based on climatological data and energy flow, this paper analyzes the behavior observed in microclimatic an important remnant of cerrado in the São Paulo State. The seasonal climate is well marked, in the study area, with two climatic periods (one dry and one wet). The vegetation presents physiology as a function of water availability and the local thermal conditions and can be seen marked changes in the landscape due to the more or less presence of solar radiation. It’s important to understand the ecosystems behave in the context of global change. It has gained the attention of many researchers in the world.

Pesquisa etnográfica com crianças: caminhos teórico-metodológicos

This paper discusses methodological issues in educational research with young children. It approaches qualitative ethnographic research, highlighting participant observation as one of the most appropriate strategies for research developed in schools for children in the first two years of basic education, in other words, students between six and seven years old. It is suggested that ethnographic research and participant observation can diminish the differences between observer (adult) and observed (kids), when considering the peer culture in childhood , allowing the researcher to insert itself in a more properly way on a cultural reality of a given group. Furthermore, it is necessary to respect ethical principles, consider the specificities of young children and use various strategies to generate empirical data in order to enable them to participate more actively in educational research in which the object of study is childhood. Thus, young children could be recognized as producers of knowledge and subject of the investigative process.

Obtenção de neurônios de redes neurais de base radial via agrupamento de dados por floresta de caminhos ótimos

Neste artigo é apresentada uma abordagem para aumentar a eficácia das Redes Neurais Artificiais de Funções de Base Radial utilizando um algoritmo de agrupamento de dados via Floresta de Caminhos Ótimos. Algumas técnicas comumente empregadas para essa tarefa, como o conhecido k-médias, requerem um determinado número de classes/agrupamentos prévio à sua execução. Embora o número de classes seja conhecido em problemas supervisionados, o número real de agrupamentos é difícil de ser encontrado, dado que uma classe pode ser representada por mais de um agrupamento. Experimentos em nove bases de dados, em conjunto com análises estatísticas, demonstraram que o classificador por Floresta de Caminhos Ótimos possui um melhor desempenho que a técnica k-médias, bem como encontra as médias das distribuições Gaussianas em posições muito similares às encontradas por este último. Entretanto, o classificador por Floresta de Caminhos Ótimos possui um custo computacional maior, dado que a sua etapa de treinamento é mais custosa que a da técnica k-médias.
