[Ecology as a center of interest]. / La ecología como centro de interés. La enfermera comunitaria en salud ambiental.

The authors discuss the role of community health nursing in environmental health by means of a review of current literature about this topic, setting up the most adequate search method. As a result of this review, the authors found these articles to be the most interesting: MEDLINE: 30 precision rate (TP): 31%; CINALH: 17, TP 31%; CSIC ICYT. 4, TP 22%; DISSERTATION ABSTRACTS: 2, TP 13%. The most effective search strategy was "community health nursing and environmental health". The need to analyze the role of nursing in environmental health does not appear in articles until 1990. Conceptual analysis of this topic has already occurred; its practical application is the present challenge. The preliminary results of this research project were presented at the VIII Congress of the Spanish Association of Public Health and Sanitary Administration.

[Making decisions. A conceptual approximation]. / Tomar decisiones. Una aproximación conceptual.

Decision making is constant in all aspects of the nursing field, including management, professional development, investigation and assistance. But, What can be stated about the mechanisms and procedures which lead us to adopt a decision? By means of the considerations taken into account, and bearing in mind that in our country there are no research articles which deal with decision making in nursing, the authors make a bibliographical review which contributes to a critical discussion about this topic and which brings to bear elements of reflection for decision making in daily nursing practice. First, the authors deal with the origins and the evolution of decision making models in clinical practice so that they may later analyze decision making in nursing.
