The purpose of this study was to identify trends for studies published in the Journal of Korean Academy of Nursing and journals published by member societies from inaugural issues to 2010.

A total of 6890 studies were analyzed using descriptive statistics.

Quantitative studies accounted for 83.6% while qualitative studies accounted for 14.4%. Most frequently used research designs were quasi-experimental (91.1%) for experimental research and survey (85.2%) for non-experimental research. Most frequent study participants were healthy people (35.8%), most frequent nursing interventions, nursing skills (53.5%), and 39.8% used knowledge, attitude and behavior outcomes for dependent variables. Most frequently used keyword was elderly. Survey studies decreased from 1991 to 2010 by approximately 50%, while qualitative studies increased by about 20%. True experimental research (1.2%) showed no significant changes. Studies focusing on healthy populations increased from 2001-2005 (37.5%) to 2006-2010 (41.0%). From 1970 to 2010, studies using questionnaire accounted for over 50% whereas physiological measurement, approximately 5% only. Experimental studies using nursing skill interventions increased from 1970-1980 (30.4%) to 2006-2010 (64.0%). No significant changes were noted in studies using knowledge, attitude and behavior (39.9% ) as dependent variables.

The results suggest that further expansion of true experimental, qualitative studies and physiological measurements are needed.

The purpose of this study was to describe sexual behavior and understand the correlation between knowledge and attitude of contraception and provide preliminary data to develop a sex education program.

The subjects of this study were 400 university students. Data was collected from November 14 to 20,2005 by using structured questionnaires.

The percent of subjects that experienced sexual intercourse was 32%. The respondents' score of knowledge of contraception was a mean score of 15.33 on a scale of 20 and there were significant differences in major departments, existence or nonexistence of sexual intercourse and sexual knowledge. The respondents' score of attitude of contraception was a mean score of 40.98 on a scale of 60 and there were significant differences in sex. There was no significant correlation between knowledge and attitude of contraception.

A sex education program that uses practical knowledge and attitude of contraception to prevent conception should be developed rather than the present sex education that only attaches schoolbook knowledge.

This research has been conducted in order to understand the major factors that affect self-esteem of adolescents.

Data was collected by questionnaires from 1155 students at middle and high school in Seoul and Kyungkido, Korea. The Instrument tools utilized in this study were self-esteem, body-image, problematic behavior, depression, school adjustment, social support tool and thoroughly modified to verify validity and reliability. The collected data have been analyzed using SPSS 11.0 program. The variable of family harmony and counseling partner was treated as a dummy variable. Seven outliers which were bigger than 3 in absolute value were found, so after taking them off, Multiple Regression was used for further analysis.

The major factors that affect self-esteem of adolescents were depression, social support, body-image, problematic behavior, school adjustment, and family harmony, which explained 54.7% of self-esteem.

It has been confirmed that the regression equation model of this research may serve as a self-esteem prediction factors in adolescents.
