A topologia que envolve compartilhamento do meio físico é bastante eficiente para transmissão de dados, que embora exijam baixas probabilidades de erros, são bastante tolerantes com relação a atrasos, suportando dessa forma retransmissões e congestionamentos. As aplicações multimídia nas redes locais, no entanto, apresentam restrições severas quanto a atrasos, ocupam grande banda e requerem transmissões a altas taxas, tomando assim a topologia física de acesso múltiplo inadequada e requerendo a migração para outra base tecnológica. Essa base é o ATM (Asyncronous Transfer Mock). Devido ao fato de a tecnologia ATM ser relativamente nova no ambiente das redes locais, representar maior investimento financeiro e ser mais complexa tanto na implantação quanto no gerenciamento, existe a necessidade de planejamento. Nesse contexto se insere este trabalho, no qual são apresentadas as características básicas do ATM, sua aplicabilidade nas redes locais e um aplicativo matemático-computacional destinado à implantação da tecnologia ATM nas redes locais / Abstract: The technological advances and the offer of new services, like voice and interactive video and graphic data transmission, have generated a need of changes in traditional local area networks. The topology that involves shared media is quite efficient for data transmission applications, which require low error probabilities but are very tolerant to delays, supporting retransmissions and congestions. The multimedia applications in local area networks, however, have strong delay constraints, need large bandwidth and require transmission at high rates, making the multiple access topology inadequate and creating a need for another technology. This technology is ATM (Asyncronous Transfer Mode). As ATM is new in the local area networks environment, its implantation and management are more complex and require higher financial investiments, leading to the need of careful planning. This work is inserted in this context, presenting the basic characteristics of ATM, its aplicability in local area networks, and a software designed for suporting ATM-based LANs / Mestrado / Mestre em Engenharia Elétrica

A positive safety culture has been shown to contribute to a firm's ability to avoid or reduce the occurrence of occupational accidents and injuries. In American workplaces alone 3,582 people died and 5.1 million people were disabled in 2009 and the cost to corporate America was $169 billion and an additional productivity loss of 95 million work days. The economic cost to each American household is about $1,200. Firms that establish and maintain a positive safety culture are able to achieve a competitive advantage in the market. While much research exists showing the relationship between safety culture and accident reduction, less guidance is found on how companies might achieve such improvement through cultural change. Attempts have been made to determine the factor structure of safety culture, that is, the identification of the antecedents of a positive safety culture. However, to date no general consensus has emerged among researchers about the exact elements of the factor structure. Research methodologies have been blamed for biasing the research results and thereby causing the lack of consensus. This dissertation uses a different methodology, the Delphi method combined with Hofstede's well-known onion model of organizational culture, to determine those organizational practices that lead to a positive safety culture. Delphi is a mixed methodology that begins with an exploratory approach followed by the more traditional quantitative method. The exploratory front-end was deemed appropriate given that prior traditional survey instruments most likely introduced researcher bias through a myopic view of safety culture. Delphi also differs by utilizing purposeful sampling versus random sampling which provides a high level of expertise to inform the research. After four rounds of inquiry with a panel of experts, a consensus was reached on 18 organizational practices that lead to a positive safety culture. This research adds to the understanding of safety culture, provides useful information for both practitioners and academic researchers, and offers launch points for extensions of the research.
