Estratégias para disseminação do conhecimento organizacional: o papel da arquitetura da informação

Introduction: Organizations are expending more and more, the spaces electronic / digital (Internet / intranet / extranet) as a way to efficiently manage information and knowledge in the organizational environment. The management of inputs informational and intellectual belongings ranges from the strategic level to the operational level; the results demonstrate the strength of the socialization of organizational strategies. Objective: To reflect on the role of information architecture for the development of electronic spaces / digital in organizational environments. Methodology: Analytical study supported by specialized literature, based on three aspects emphasized by Morville and Rosenfeld (2006) and applied to information architecture: context, content and user studies beyond the search and use of information Choo (2006) which also highlights three aspects: situational dimensions, cognitive needs and emotional reactions. Results: In the context of the Web environment organizations have a large number of sites for brands / products that have mostly no organizational structure or shared navigation. The results show that when a department needs to contact another department must do so in order offline. Conclusion: The information architecture has become essential for the development of management information systems that makes possible to easily find and access data and information, as well as helps in developing distinct hierarchies to structure the distribution of content, promoting developed quality and effectiveness of the management systems.

Control preventivo dinamico de sistemas de energia electrica usando redespacho de generacion y corte de carga

A model for preventive control in electrical systems is presented, taking into account the dynamic aspects of the network. Among these aspects, the effects provoked by perturbations which cause oscillations in synchronous machine angles (transient stability), such as electric equipment outages and short circuits, are presented. The energy function is used to measure the stability of the system using a procedure defined as the security margin. The control actions employed are load shedding and generation reallocation. An application of the methodology to a system located in southern Brazil, which is composed of 10 synchronous machines, 45 busses, and 72 transmission lines. The results confirm the theoretical studies.
