Para os sistemas computacionais que processam línguas naturais, como os de tradução automática, os recursos léxico-conceituais bilíngues ou multilíngues são de extrema importância. Consequentemente, o desenvolvimento de tais recursos tem ocupado lugar de centralidade no Processamento Automático das Línguas Naturais (PLN). Para o português do Brasil (PB), os recursos desse tipo ainda são escassos. Neste trabalho, apresenta-se REBECA, uma base de dados léxico-conceitual bilíngue desenvolvida para o par de línguas “inglês americano-PB” (Ingl-PB). Na introdução, contextualiza-se o projeto de desenvolvimento dessa base. Na sequência, apresentam-se (i) o equacionamento metodológico do projeto, enfatizando as atividades de pesquisa realizadas em cada uma das etapas previstas pela metodologia, (ii) a construção da base com o auxílio do editor de ontologias Protégé-OWL, (iii) as principais características e potencialidades da base REBECA e, por fim, (iv) as possíveis extensões e algumas considerações finais.

The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.

Atmospheric Discharges are responsible for several lost in the electrical system therefore it´s done studies to find ways to reduce the problem caused by discharges. This branch of engineering is necessary the gathering, stock and analysis of large quantity of data to validate or refuse the many studies produced about it The CENDAT proposed a project to collect data on induced voltages in distribution lines and current waveform of the lightning, but a difficulty that arose was the accumulation of data due to lack of manpower available to catalog all the data collected. Thinking in this difficulty, the engineer Acacio Silva Neto CENDAT´s researcher with trainees began to develop a program to solve this problem. This work keeps the development of this program in order to solve the problem of accumulation of data

In the architecture of a natural language processing system based on linguistic knowledge, two types of component are important: the knowledge databases and the processing modules. One of the knowledge databases is the lexical database, which is responsible for providing the lexical unities and its properties to the processing modules. The systems that process two or more languages require bilingual and/or multilingual lexical databases. These databases can be constructed by aligning distinct monolingual databases. In this paper, we present the interlingua and the strategy of aligning the two monolingual databases in REBECA, which only stores concepts from the “wheeled vehicle” domain.
