Purpose: Aim of this study was to gather and evaluate perceptions of investigators, IRB members, and IRB administrators on the appropriateness of IRB review process and bioethical oversight system of national R&D (NR&D) projects. Method: Investigators, IRB members, and IRB administrators at 17 different institutions were surveyed using convenience sampling and survey questionnaires were partially group-specialized to consider any differences between the groups. Results: Participants included 29 investigators, 37 IRB members, and 17 administrators with response rate of 100% (83 of 83). According to the responses obtained, insufficient preparation time for constructing protocol and gaining IRB approval was one of the main problems in the IRB review process (investigator 79.3%, IRB administrator 88.2%). Also, discrepancy between NR&D and IRB's protocol formats was another major issue (IRB members 96.4%, IRB administrator 100%) and most investigators (89.7%) had to modify the original NR&D protocol to obtain IRB approval. Moreover, it was reported that 13.8% of investigators and 31.3% of IRB administrators did not submit midyear reports to IRB and for bioethical issues of NR&D projects, 17.2% of investigators did not include information on project status and safety issues in the annual reports. Conclusion: In conclusion, for successful and ethical completion of R&D projects, revision of both IRB review process and NR&D project protocol formats as well as implementation of appropriate bioethical oversights are necessary.

Purpose: The purpose of this study was to determine the relation between test anxiety and mental health in adolescents. Method: The subjects were 450 students of two academic high schools in J City, who were selected through convenient sampling. Data were collected through a survey using a structured questionnaire from September 1st to 15th 2005. Collected data were analyzed using SPSS 10.0 for Windows through descriptive analysis, Pearson's Correlation Coefficient, t-test, ANOVA, Scheffe's test and stepwise multiple regression. Result: The mean score of test anxiety was 2.40 (range:1.13-3.81) and that of mental health was 2.77 (range:0.64-5.03). A significant negative correlation was observed between test anxiety and mental health (r=-0.28, p=.000). Test anxiety was significantly different according to adolescents' general characters such as gender (t=-1.98, p=.048), grade (F=3.54, p=.030), school life satisfaction (F=10.73, p=.000) and relationship with the teacher (F=11.60, p=.000). Mental health was significantly different according to adolescents' general characters such as religion (t=2.14, p=.032) and school life satisfaction (F=4.13, p=.017). The most powerful predictor of mental health was test anxiety and it, combined with religion, accounted for 9.0% of variance in mental health in adolescents. Conclusion: Test anxiety and mental health was found to be in a significant negative correlation with each other in adolescents. Therefore, nursing intervention programs for adolescents needs to reduce their test anxiety to improve their mental health.

The purpose of this study was to identify menstrual discomforts and coping m adult women. The subjects were 577 adult women. aged 20 years old and over. selected by convenient sampling. Data were collected through a questionnaire survey from December 2. 2004 to December 31. 2004. Two instruments were modified and used in this study. the Menstrual Discomfort Questionnaire by Park(1988) and the Menstrual Coping Questionnaire by Billings & Moos(198l). The data were analyzed by descriptive statistics. t-test. and ANOVA with SPSS 10.0 program. The results of this study were as follows. 1. The prevalence rate of dysmenorrhea was $85.6\%$. 2. The total mean score for menstrual discomforts was 2.82 of a possible total of 5. The mean score for each category was 3.10 for water retention. 2.93 for negative affect. 2.89 for pain. 2.74 for autonomic reactions. 2.73 for behavioral change. and 2.59 for concentration. 3. Statistical differences were found for menarche age(F=9.351. p<.00l), feeling to menstruation(F=12.376. p<.001). dysmenorrhea(t=7.3l7. p<.001). onset of dysmenorrhea (F= 12.766. p<.001). taking medication(t=6.289. p<.001). and degree of taking medication (F=12.924. p<.00l). 4. The coping modes with the highest scores were 'rest and go to the bed '$(83.3\%)$. 'regard menstruation as a physiological and temporary phenomenon' $(68.6\%)$, and 'take a warm shower' $(64.5\%)$. We conclude that there were many women with dysmenorrhea. that the first day was the onset of menstrual discomfort. and that it differed by menarche age. feeling to menstruation. dysmenorrhea. onset of dysmenorrhea. taking medication. and degree of taking medication. Nursing intervention has to be considered in programs to reduce menstrual discomfort.

The purpose of this study was to identify health behaviors of elderly with osteoarthritis across gender groups. Total of 1,654 age 65 over from the fifth Korean National health and Nutrition Examination Survey (KNHANES) were selected. The data analysis was performed using the complex sampling function of SPSS version 20. Logistic regression analysis shows the difference of risk factors of osteoarthritis between men and women elderly people. Prevalence of osteoarthritis in men elderly was associated with drinking, education for osteoarthritis, and treatment of osteoarthritis whereas the factors in woman elderly were depression and muscle strengthen exercise. Most of the subjects had not the opportunity of education of the management of the osteoarthritis. These findings from the study are expected to promote the screening strategy for the aged at risk of osteoarthritis in the Korean community and enhance the effect of the nursing intervention for the elderly with osteoarthritis.

Outliers in surveys can have a large effect on estimates of totals. This is especially true in business surveys where the populations are drawn are typically skewed. In this paper, we discussed the practical development and implementation of methods to identify and deal with outliers. A detection method is based on quartile method and detected outlier is processed in various ways. The study examines two versions of winsorised estimators with three different cut-off thresholds for each one. For the simulation study, four types of weight transformation function have been considered.

Purpose: This study aimed to identify the relationships among physical symptoms, activities of daily living, and health-related quality of life (HRQoL) in community-dwelling older adults. Methods: A stratified random sampling method was conducted to recruit participants from May 10 to August 17, 2007. Physical symptoms were measured using the Physical Health Questionnaire (PHQ), activities of daily living using the Late-Life Functional and Disability Instrument (LLFDI), and HRQoL using the Medical Outcomes Short-Form Health Survey (SF-36) in 242 community-dwelling elderly Korean people. Results: The HRQoL correlates with the physical symptoms (r=-.31) and the function component (r=.59). Of the two disability parts of the LLFDI, the limitation dimension correlates higher (r=.57) with HRQoL than the frequency dimension (r=.42). The HRQoL is significantly associated with the function component, and disability limitation in capability which explained 44.4% of variance in physical health. Conclusion: These results may contribute to a better understanding of physical symptoms, activities of daily living, and HRQoL in community-dwelling older adults. Therefore, health programs for prompting older adult's health should be planned based on results of the study.

Purpose: This study was done to develop and validate a measure to evaluate the Korean version of psychological insulin resistance (K-PIR) in patients with diabetes in Korea. Methods: Items were initially generated from literature reviews and interviews with 19 patients with diabetes. The content validity of the items was evaluated by experts. Participants were 424 patients with diabetes recruited through convenience sampling. A cross-sectional survey was designed for item-analysis, exploratory factor analysis with principal axis factoring, and confirmatory factor analysis. Cronbach's alpha was calculated to measure the internal consistency. Results: For the 24 items of the Korean version of psychological insulin resistance, six items were eliminated because of low correlation with the other items. Exploratory factor analysis with 18-item showed that two factors (psycho-cognitive factor and supportive factor) explained 41.8% of the variance, and the factor structure of K-PIR model had a good fit. Internal consistency of K-PIR with 18 items revealed good reliability. Conclusion: The findings show that the K-PIR is reliable for measuring the psychological resistance to insulin therapy for Korean patients with diabetes. However, further study is needed to evaluate the validation because the proportion of variation of K-PIR was low in this study.

Pediatric and adolescent dental anxiety and fear have been researched in the connection with behavior modification for a long time and this dental anxiety can persist until the adult hoods resulting in extreme fear of and avoidance of dental treatments and causes oral health deterioration. However, the domestic researches regarding adolescent dental anxiety and fear are insufficient. For this reason, this study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Gyeonggi-Do. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students. The distribution of responses in each category of fear was examined by frequency analysis. The analysis was conducted using cross tabulation in order to examine the difference between male students and female students and using independent sample t-test in order to compare the fear score of each category. The study results showed the fear score of female students for the category 'causing irritation during the dental treatments' was significantly higher in statistics(p<0.05). Therefore, these results should be reflected to the dental care environments in order for the adolescent to reduce the dental anxiety and fear.

Purpose of this study is to investigate influence on preference of cohousing (eg. intention to spread and intention to move in cohousing) according to sense of community, especially in housing life by married people residing in Seoul and its outskirts. Research method used for this study was a social survey. Respondents were 214 people by accidential sampling. The collected data were analyzed by SPSS 12.0 program using frequency, mean, average, T-test, one-way Anova, Duncan's Multiple Range test and Chi-square test. Findings of this study were as follows. Most respondents took part in interactive activities with colleagues from the same occupation. They Focused on the issues about health, leisure and hobby. The respondents mainly wanted to have interaction for changing recycling materials and education programs for children and juveniles. Degree of ideal relationships with neighbors, they think, were greeting and chatting as well as communication about issues on child-care, education for children, offense-prevention and safety. Although respondents were interested in community life and in interaction with their neighbors, they did not build up communal society due to lack of a sense of belonging in their living areas. While respondents showed positive response about preference of cohousing, there were difference between intention to spread of cohousing and intention to move in cohousing. As a result of this study, the stronger sense of community in housing life meant the more interests in thoughts to spread and to move in cohousing. Therefore, in order to increase sense of community in cohousing, the plan of various communication programs that enables frequent interaction among neighbors is needed. Also, in order to spread cohousing in Korea, promotion of cohousing community and cognitions about it are the most needed.
