[A contribution to occupational health: a guide on the exposure to biological fluids].

Health workers are exposed to occupational hazards at the workplace, among which we highlight the biological risk. Information and orientation should be provided regarding the conduct that workers are expected to follow in the case becoming exposed. Thus, this guide is intended to provide the elements to orient workers' conduct in cases of biological exposure, improving adherence to the monitoring protocol.

Classification of risk micro-areas using data mining.

Objective: To identify, with the assistance of computational techniques, rules concerning the conditions of the physical environment for the classification of risk micro-areas.

Methods: Exploratory research carried out in Curitiba, Southern Brazil, in 2007. It was divided into three phases: the identification of attributes to classify a micro-area; the construction of a database; and the process of discovering knowledge in a database through the use of data mining.
