PURPOSE
The purpose of this study was to describe the sexual behavior, health risk related to reproductive health, and characteristics of sexual experience among college students in Korea.
METHODS
Six thousands college students were selected through proportional quota sampling based on region, college, and gender. Structured questionnaires were used for data collection. Descriptive statistics and chi-square test were used to describe the data.
RESULTS
Thirty eight percent (N=2,285) of the participants reported sexual intercourse. The mean age of first time sexual intercourse was 19.3 years old. Respondents reported the following health risks such as smoking, drinking, not exercising, no regular meal patterns, chronic disease status, and weight loss over 10 kg in the past three months showed significant differences by sexual intercourse experience (p<.01). Among those who had sexual intercourse experiences, 7.1% of them reported having a history of STDs and 11.6% reported a pregnancy or pregnancy of one's partner.
CONCLUSION
The findings of this study reflect the current trends of sex behaviors among college students and correlations between health risks related to reproductive health and sexual intercourse experiences. Developing reproductive health education programs based on the findings and providing the programs to college students through a school nurse is suggested.

PURPOSE
The purpose of this study was to evaluate the influence of the Koryo Hand Acupuncture Therapy on middle-age women's obesity index.
METHODS
A total of 38 middle-age women were assigned to either a control or an intervention group. The intervention group received Koryo Hand Acupuncture Therapy three times a week for ten weeks. The two sample t-test was used to compare the body mass index, fat mass, and waist-to-hip ratio between the intervention (n=18) and the control group (n=20).
RESULTS
In both groups, body mass index did not change significantly following the intervention. The intervention group lost 1.00+/-1.10 kg of fat mass (p=.00) and the decrease was significant between the intervention and control group (p=.00). Both groups had increase in waist-to-hip ratio, however, the increase was only significant for the control group (p=.00).
CONCLUSION
The application of Koryo Hand Acupuncture Therapy influenced the change of fat mass, but not clinically significant. It may be useful to repeat the study and to examine other factors that may have interfered with the effectiveness of the intervention. The use of Koryo hand acupuncture therapy should be further studied.
