PURPOSE
The purpose of the study was to develop a knowledge scale of risk factors for fall among community-dwelling older adults. Further, the validity and reliability of the scale was developed.
METHODS
A preliminary scale was developed through content validity by five experts and targeted subjects using the CVI (Content Validity Index). Following the establishment of content validity, the scale was used with 359 community-dwelling older adults to further establish both validity and reliability of the scale. Specifically, construct validity using known-group comparison technique, and reliability using Cronbach's alpha were established.
RESULTS
After content validity testing, 44 preliminary items were selected. Construct validity was established by known group-comparison, in which scores between the fall and no fall groups were compared. The Cronbach's alpha of the final scale was .83.
CONCLUSION
Reliability and validity of the scale were confirmed. This tool may be used for measuring knowledge of fall risk factor for the community-dwelling older adults.

PURPOSE
The purpose of this study was to examine the effects of an educational program about reproductive health promotion on sexual knowledge and attitudes of university students. METHODS: The sample included 79 students of all grades from 3 universities in Korea. Data were collected from 8th to 11th of January, 2008 by using a structured questionnaire administered before and after the educational program. The data were analyzed using SPSS/WIN 12.0 program. RESULTS: The students' scores on sexual knowledge increased, and attitudes toward sexuality changed at the completion of the educational program. The program was especially effective in 'physiology', 'contraception and abortion' and 'venereal disease and AIDS' among sexual knowledge, and in 'intercourse' and 'sexual morality' among sexual attitudes. CONCLUSION: The results of this study show that an educational program about reproductive health increases sexual knowledge and changes the sexual attitudes of university students.
