PURPOSE
This study was to evaluate clinical competence in relation to self-directed learning, critical thinking disposition, and participating in PBL(Problem-Based Learning) group activities of nursing students.
METHODS
Data were collected from 108 nursing students in Oct. 2006.
RESULTS
Clinical competence had a significant positive correlation with self-directed learning, critical thinking disposition, and participation in PBL group activities. There was a significant difference in clinical competence according to interpersonal relationship. Participation in PBL group activities was the most influential factor of clinical competence(R2=.34). Also, the influence of clinical competence increased with the addition of self-directed learning(R2=.42).
CONCLUSION
It is essential to encourage the self-directed learning and participation in PBL group activities for the improvement of clinical competence. It is relatively important for clinical competence to consider the educational environment systematically.

The purpose of this study is to present an actual example for procedures for developing a PBL package based on philosophical backgrounds derived from Problem-based learning. To perform a systemic study on the operations of an intergrated curricula under multi-disciplines, a research team made up of several professors with different academic backgrounds was formed. Among the four situations for the patients with perception-adjustment disorder, especially a procedure for the development of PBL package which can be used in the emergency room situation has been proposed. The little(2000)'s PBL package model has been applied for this study. Tha package includes course objectives, learning objectives, concept map, situation scenario, tutor guide, and evaluation method. It is believed that learning objectives achievement procedures designed as a part of a problem-based learning package development procedures for the nursing of patients with perception-adjustment can be achieved at the same level as the learning objectives for the science of nursing founded by the Korean Nurses Association.
