Aiming at this characteristic, this paper brought forth the Rough Set （RS） theory to the field of fault diagnosis. By means of the RS theory which is predominant in the way of dealing with fuzzy and uncertain information, knowledge access about fault diagnosis was realized. The foundation ideology of the RS theory was exhausted in detail, an amended RS algorithm was proposed, and the process model of knowledge access based on the amended RS algorithm was researched. Finally, we verified the correctness and the practicability of this method during the procedure of knowledge access.展开更多

By mostly using existing institutions and funding sources, we can build this as well as compensate authors within the current worldwide library budget. We should take advantage of our new technologies and our open societies to make a Universal Library again, and go the next step and make all knowledge easily available to every man, woman and child around the world.展开更多

The study is exploratory, descriptive, and qualitative type, such as a survey, developed through an adaptation of a relevant research, which involves the standardization of data collection instruments （questionnaires and interviews） applied directly to persons of a specific population, to assess knowledge management tools present in the University Hospital portals in the northeast region of Brazil. The results indicated that the resources from knowledge access were more prevalent than the others, ratifying the results found in research developed in Asian and North American Hospital portals.展开更多
