Abstract: the purpose of this study is to test the sensitivity of the volumetric analysis compared to the visual analysis of the hippocampal formations of a group of 153 patients with clinical diagnosis of temporal lobe epilepsy and candidates to temporal lobectomy, evaluated by magnetic resonance (mr), using a 0.5 tesla machine and inversion-recovery t1-weighted images and 5 mm coronal slices. there was agreement between the prospective visual analysis and another retrospective visual analysis carried out by two independent observers (c=0.748 and c=0.720). there was also agreement between the retrospective analysis of the two investigators (c=0.733). there was genuine agreement (c=0.788) between the results of the qualitative and quantitative analyses carried out prospectively. volume measurements showed a nonsignificant tendency to lateralize more cases of clinically presumed hippocampal atrophy. our results confirm the reliability of a qualitative visual analysis and indicate the utility of hippocampal volumetry as a supplementar, objective and quantitative measure of hippocampal sclerosis.

Abstract: Visando comparar a sensibilidade da avalia o volumétrica com a análise visual na avalia o por ressonancia magnética (RM) das forma es hipocampais de pacientes com epilepsia do lobo temporal refratária e candidatos à lobectomia temporal, estudamos 153 casos com diagnóstico clínico de epilepsia do lobo temporal, utilizando um equipamento de 0,5 Tesla, com técnica de inversion-recovery ponderada em T1, com cortes de 5 mm no plano coronal. Houve boa concordancia entre a análise visual prospectiva e outra retrospectiva, realizada por dois observadores independentes (C=0,748 e 0,720). Houve também concordancia entre a análise retrospectiva dos dois observadores (C=0,733). Houve ainda concordancia genuína (C=0,788) entre os resultados das análises quantitativa e qualitativa realizadas prospectivamente. A análise quantitativa demonstrou uma tendência n o-significativa a lateralizar mais casos de atrofia hipocampal presumida clinicamente. Nossos resultados confirmam a confiabilidade da análise visual qualitativa e indicam a utilidade da volumetria hipocampal como uma medida suplementar, objetiva e quantitativa, de esclerose hipocampal.

Oliveira, Silmara A. V. de;Castro, Maria Júlia M. de O.;Bittencourt, Paulo Rogério M.;
Arquivos de Neuro-Psiquiatria , 1989, DOI: 10.1590/S0004-282X1989000100009
Abstract: slowly progressive aphasia has been found in 8 published cases, 2 of whom progressed over a period of years to generalized dementia. positron emission tomography demonstrated decreased glucose metabolism in the left perisylvian region in 2 cases. we describe a patient who had slowly progressive aphasia and developed generalized alzheimer's dementia 7 years after presentation. there was no clinical or laboratory evidence of concomitant disease. computerized tomography showed generalized atrophy more marked on the left perisylvian region late in the disease, when eeg showed generalized slowing more marked on the same area. slowly progressive aphasia of old age should be considered a separate entity until further studies elucidate its relation to alzheimer's dementia.

Bittencourt, Paulo Rogério M.;
Arquivos de Neuro-Psiquiatria , 1988, DOI: 10.1590/S0004-282X1988000400008
Abstract: the previously described anti-spastic effect of oxcarbazepine and 10,11-dihydro-10-hydroxycarbamazepine was found accidentally in 2 patients undergoing a double-blind comparative study lor evaluation of antiepileptic effect. in this study oxcarbazepine was given orally in doses of 300-2700 mg daily to one patient with transverse myelitis and to two patients with multiple sclerosis, all of whom had clinically disabling spasticity in the form of difficulty in walking, lower limb rigidity, spastic contractions of the lower limbs and ankle clonus. anti-spastic effect was observed at doses between 600-1200 mg daily and consisted in a substantial decrease in the above symptoms of spasticity. the anti-spastic effect appears at a dose immediately below that which produces nausea, dizziness and somnolence.

Abstract: Robot World Cup Initiative (RoboCup) is a worldwide competition proposed to advance research in robotics and artificial intelligence. It has a league called RoboCup soccer devoted for soccer robots, which is a challenge because robots are mobile, fully autonomous, multi-agents, and they play on a dynamic environment. Moreover, robots must recognize the game entities, which is a crucial task during a game. A camera is usually used as an input system to recognize ball, opponents, soccer field, and so on. These elements may be recognized applying some tools of computational intelligence, for example an artificial neural network. This paper describes the application of an artificial neural network on middle size robotic football league, where a multilayer perceptron neural network is trained with the backpropagation algorithm, to classify elements on the image. Each output neuron represents an entity and its output value depends on the current entity that is present on the image. The results show that an artificial neural network successfully classified the entities. They were recognized even when similar color entities were present on the image.

Abstract: Este artigo apresenta um panorama sobre os conceitos relacionados à informa o e ao conhecimento, em especial sobre sua agrega o aos processos de produ o de bens e servi os de natureza inovadora. Apresenta, ainda, um conjunto de reflex es sobre o processo de inova o e suas conex es com o desenvolvimento econ mico e social, identificando as principais características dos ambientes mais apropriados para a gera o de inova es, bem como as estratégias para estimulá-las. Para situar o tema, foram abordados alguns aspectos do processo a que se convencionou chamar de globaliza o, enquanto fen meno social e econ mico que permeia o debate sobre as novas formas de produ o, cada vez mais demandantes de gera o e agrega o de conhecimento a bens e servi os. Nesse contexto, discute-se a influência da rápida evolu o das tecnologias da informa o e comunica o (TIC) sobre os processos de gera o do conhecimento e de produ o de bens e servi os, colocando em evidência os principais requisitos de estímulo ao desenvolvimento sócio-econ mico, configurados em políticas públicas apropriadas ao incentivo da atividade produtiva. Sobre isso, é feita uma breve análise da atual Política Industrial, Tecnológica e de Comércio Exterior – PITCE e de um de seus mecanismos de estímulo à inova o, a recentemente aprovada Lei de Inova o. This paper presents a scenario about the concepts related to information and knowledge, especially on their contributions to innovative production processes of goods and services. It also presents some reflections about the innovation process and its relations to the social and economic development, identifying the main features of the most suitable environment for innovation and the strategies to stimulate them. To pose the theme some aspects of globalization process were explored, as a social and economical phenomenum, which supports the current discussion on new methods of production. These methods demand, more and more, generation and application of knowledge. In this context, the fast evolution of information and communication technologies and its influence on the production processes is discussed, in the light of the main requirements of appropriate public polices for stimulating the productive activities. In conclusion, this work presents an summary of the strategies adopted by the Brazilian State to promote economic growth and social welfare, mainly trough the definition of industrial, science and technology polices, for example The Industrial Technological and Foreign Affairs Police –PITCE, specially one of their mechanisms for innovati

Abstract: Este trabalho tem como premissa demonstrar o uso de comunidade virtual como forma de amplia o do campo das rela es em conformidade com o objetivo de ensinar e aprender. Para melhor entender a quest o realizou-se levantamento bibliográfico da literatura a respeito do tema e posterior observa o da comunidade objeto do estudo. A partir das leituras feitas e da análise da comunidade em seu período ativo foi possível perceber o entendimento do uso nessa comunidade virtual de aprendizagem e as quest es que nortearam o seu fluxo. Fica claro que a tecnologia é a ferramenta que possibilita o incremento da comunidade como um instrumento potencializador da comunica o, mas, constata-se que sem o sentimento de pertencimento e o trabalho colaborativo a constru o do conhecimento coletivo n o atinge resultados satisfatórios. This work has as premise to demonstrate virtual community's use as form of enlargement of the field of the relationships in accordance with objective of teaching and learning. To understand the subject it took place bibliographical rising of the literature regarding the theme and subsequent observation of the community object of the study. Starting from the readings and the community's analysis in it active period was possible to notice the understanding of the use in that virtual community of learning and the subjects that orientated it flow. It sure that technology is the tool that makes possible the community's increment as instrument potentialities of the communication, but, it is verified that without the concerning feeling and the collaboration work the construction of the collective knowledge doesn't reach satisfactory results.

Abstract: A sociedade atual passa por rápidas transforma es. Antigos paradigmas estabelecidos têm sido colocados em xeque e o professor que antes dominava todo o conteúdo tem dado lugar a um novo tipo de profissional, capaz de mobilizar os conhecimentos, transformando-os em a o. Temos hoje a necessidade de um professor profissional capaz de organizar situa es de aprendizagem, com autonomia para tomar decis es ao mesmo tempo em que seja capaz de refletir acerca de sua própria a o. Neste trabalho estaremos apresentando uma proposta de capacita o de Educa o Tecnológica para professores em exercício no Ensino Fundamental, ao mesmo tempo em que classificamos através de uma análise qualitativa de estudo de caso, as opini es que os mesmos apresentam sobre o que venha a ser tecnologia. Este levantamento é fundamental para se estabelecer um consenso, visto que a tecnologia é tratada de maneira bastante diversificada e na maioria das vezes de forma err nea seja a nível informal ou ainda em propostas oficiais. The present society goes through fast transformations. Old established paradigms have been placed in xeque and the teachers who used to dominated all the content have given place to a new professional that is able to mobilize the knowledge and transform it into action. Today, we need a professional teacher able to organize learning situations with autonomy in the way to make decisions and at the same time where he is able to reflect about his own action. So, in this paper we present a proposal of a continuous technological education course to working teachers and the classification of their opinion about technology that was obtained through a case study. We think that this survey is important to establish a consensus that the technology is treated by people as formal or informal level in most of time in diversified and wrong way.
