PURPOSE
The purpose of the study was to identify levels of anxiety, stress hormone, lymphocytes, and neutrophils of the nursing students before an examination and to examine effects of social support on those variables related to taking examinations.
METHODS
Thirty eight healthy nursing students participated. They completed the questionnaire including state anxiety, test anxiety (VAS scale) and social support two weeks before the exam and again just before the exam. Simultaneously, a venous sample for ACTH, cortisol, lymphocytes & neutrophils count was drawn by a trained nurse. Descriptive statistics, paired t-test, student t-test, and Pearson's correlation with SPSS/WIN 14.0 were used to analyze the data.
RESULTS
Test anxiety scores and cortisol level on the exam day showed a significant increment compared with those on the non-exam day. The participants with higher levels of total social support scores showed significantly lower state anxiety on the exam day than those with lower levels of total social support scores.
CONCLUSION
These data indicate a possible alteration in cortisol responsiveness to academic stress in nursing students. Social support would play an important role in modulation of academic stress.

PURPOSE
The purpose of this study was to understand the experiences of interpersonal relationships of head nurses in interacting with others in general hospital settings.
METHODS
The data were collected by individual in-depth interviews from seven head nurses and were analyzed using qualitative content analysis.
RESULTS
Five major categories emerged and they represent a major strategy according to five different groups of interacting people. 'Establishing trust' was identified as the key strategy in dealing with patients and family members. 'Embracing with sisterly love' and 'helping with self-defense' were major strategies for subordinate nurses and physicians, respectively. 'Respecting and recognizing' was the main approach for other professionals such as dietitians and 'emphasizing rules and educating' were a major one for non-professionals. Head nurses paid more attention and made efforts in dealing with their subordinate nurses than with other groups of people, because they felt the most difficulty in their relationship with subordinate nurses.
CONCLUSION
The results of the study showed that head nurses employ unique strategies in interacting with different groups of people to increase the efficiency of communication. This study would help nurse administrators establish an effective program for improving interpersonal relationships of head nurse.
