Purpose
This study was conducted to develop a scale for measuring aggression in adolescents, based on Ajzen's Theory of Planned Behavior (TPB).
Methods
The participants were 38 adolescents in an in-depth study conducted to develop items for indirect measurement, 13 adolescents in a pre-test, and 289 adolescents in the present survey. The collected data were analyzed using content validity, the correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability, and the Cronbach's ⍺.
Results
In this study, the most important variable related to aggression was found to be aggression intention. This study included 4 factors of direct measurement and 6 factors of indirect measurement; therefore, 41 questions were developed. Increased levels of aggression were associated with higher scores for attitudes of aggression, subjective norms, perceived behavioral control, and aggression intention.
Conclusion
We found that the questionnaire used in this study was valid and reliable as a measurement scale to explain aggression in adolescents based on TPB. Aggression intention should be included in aggression prevention programs because it was linked to aggressive behavior.

PURPOSE
The purposes of this study were to develop an infant sleep health education program using a video for SIDS prevention education and to measure the effects of the program.
METHODS
The infant sleep health education program consisted of presentations and motor images. The formation of educational material was directed by the systematic design of instruction. Participants in this study were 59 primiparous women from postpartum care centers. The instruments used in this study were criterion referenced test items for knowledge about infant sleep health and confidence inventory. Experimental group I was given the treatment of infant sleep health education program. Experimental group II was given the program using a video reinforcement after 2 weeks. On the other hand, control group was given no treatment.
RESULTS
There was a significant increase in knowledge and confidence in the performance of mother's roles of both experimental group I and experimental group II over the control group. No significant difference was founds for knowledge and confidence in the performance of mother's roles between experimental group I and II.
CONCLUSION
The results indicate that this program is a very effective intervention for better sleep health in infants by helping the mothers increase confidence in their role performance.

PURPOSE
Purpose of this study was to identify the effects on maternal role strain, maternal role confidence and maternal identity of a maternal role promotion program for mothers of premature infants.
METHOD
A quasi-experimental non-equivalent pre-and-post test was used to compare the two groups. The data were collected from 62 mothers from September 10. 2003 to August 30, 2004 at Neonatal Intensive Care Unit(NICU) located in S. city and K. city. The maternal role promotion program was provided three times during the period from two-three days after the baby's admission to 1 month after the baby's discharge. The instruments for measurement were the Perceived Role Difficulty & Steffensmeier Scale, Self Confidence Scale and Semantic Differential Scale. Data were analyzed by means of frequency, mean and SD, x2-test and t-test.
RESULTS
There were significant differences in maternal role strain level between the experimental and control group (t=2.163, p=.035), in the maternal role confidence between the two groups(t=-5.645, p=.000) and in maternal identity between the two groups(t=-4.923, p=.000).
CONCLUSION
The results of this study indicate that the maternal role promotion program had positive effects in decreasing maternal role strain levels and increasing maternal role confidence and maternal identity.

This study was designed to determine the schemata and their characteristics of stress experience the subjectivity of stress experience(structure of subjectivity) would be a basic step for the effective clinical education through the stress management for characteristics of these types. Q-methodological method was used for that purpose. The research method statements were collected prior to the study through indepth interviews. For the study, 31 Q-statements were selected. There were 34 nursing students as subjects for the research. The 34 nursing students sorted the 31 statements using the principal of forced normal distribution. The principle of forced normal distribution, which has 9 scales to measure the individual opinions, was called. Q-factor analysis by using PC QUANL program supply the material. According to the outcomes of this study, there were 3 types of special opinion about the stress experience of clinical practice. The first type is called "Influence of practical atmosphere type". Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The second type is called "conflict of nursing role type". Members of this type experienced stress by an inadequate orientation and undesirable role model of nursing. The third type is called "Lack of confidence type". Members of this type experienced stress be cause of a lack of confidence for their own nursing knowledge and skill. As a result, we now need further study to identify individual psychological aspects of stress for clinical practice. The findings will guide the development in effective approaches for clinical education. Finally, the result of the study will provide us the need for developing systematic and integrated practice education program for students and active involvement of clinical instructor.
