Electrical systems can be categorized as critical systems where failure can result in significant financial loss, injury or threats to human life. The operators of the electric power control centers perform an activity in a specialized environment and have to carry it out by mobilizing knowledge and reasoning to which they have adequate training under the terms of the existing rules. To reach this there is a common mental request of personnel involved in these centers due the need to maintain attention, memory and reasoning request. In this sense, this study aims to evaluate the Mental Workload of technical workers of the Control Centers of Electrical Energy. It was undertaken a research on operators control centers of the electricity sector in Northeast Brazil. It was used for systematic observations, followed by interview and application of the instrument National Aeronautics and Space Administration Task Load Index known as NASA-TLX. As a result there will be subsidies for an assessment of mental workload of operators, and a contribution to improving the processes of managing the operation of electric utilities and the quality of workers.
Este trabalho tem por objetivo descrever as principais inovações tecnológicas que vêm ocorrendo no setor de fiação da cadeia produtiva da indústria têxtil no Nordeste do Brasil, tomando-se como referência um estudo de caso de uma empresa da região. São descritos o estado da arte e o histórico da evolução da indústria têxtil no Brasil e analisa-se, com base num referencial teórico da cadeia produtiva têxtil, a empresa. Também é apresentada uma visão geral do desenvolvimento tecnológico do setor, o cenário atual e o melhoramento dos seus processos produtivos. Por fim são descritas algumas razões e necessidades que levaram as empresas a se modernizarem utilizando a inovação tecnológica para melhorar a sua produtividade e qualidade dos seus sistemas de produção.
