This study is a descriptive research to identify lifestyle for health promotion, health condition, and degree of life satisfaction based on Korean elderly's physical constitution. The interviewee of this research was 53 outpatients of Oriental herbal medicine hospitals who are the residents either in Seoul or Taegu city. The data collection was performed during the March to the November of 1999. The research tools used for the measurement of the lifestyle for health promotion was "The Health Promoting Lifestyle Profile" developed by Walker, Sechrist and Pender. Measurement of the health condition was carried out using CMI(Cornell Medical Index) developed by Brodman, Erdmann, Lorge and Wolff. The Index for degree of the life satisfaction of elderly developed by Yun Jin was utilized to measure the degree of life satisfaction. Data analysis was performed using SPSSWin 9.0 software. In some cases, frequency, percentile, t-test, ANOVA or Pearson Correlation was also used to meet the specific research purposes when necessary. Tukey test was done for the post test. The conclusions are as follows. 1) The ANOVA test showed a significant difference in the lifestyle for the health promotion depending on physical constitutions of the interviewee. According to the Tukey test, 태음인 ($103.67{\pm}16.81$) performed better lifestyle for the health promotion than SOEMIN(少陰人, $85.34{\pm}12.69$) and 소양인($88.47{\pm}16.81$) (F=6.72, p=.003). 2) The result of the Pearson Correlation showed a positive correlation between the lifestyle for health promotion and health condition. As a result, the group practicing lifestyle for health promotion maintained a good health condition. Result of the Pearson Correlation also showed a proportional correlation between the lifestyle for health promotion and life satisfaction. Accordingly, the group practicing lifestyle for health promotion maintained a high degree of life satisfaction. Finally, the result of the Pearson Correlation showed a proportional correlation between the health condition and the degree of life satisfaction. Consequently, the group in a good health condition showed the high degree of life satisfaction.

Liver cirrhosis is the common cause of death in Korea today. But, if liver cirrhosis Patients were treated in the early stage of the disease Process, they can have a chance to carry their daily lives with prescribed medical and nursing regimens. Each patient has different health beliefs that there is a different Sick Role Behavior in the process of treatment. In order to increase and control the desired patient's Sick Role Behavior, it is important for nurses to understand the health beliefs influencing Sick Role Behavior. The purpose of this study was to determine factors influencing Sick Role Behavior and provide objective and scientific data to health education, treatment and nursing care. The subjects for this study were 80 Liver Cirrhosis patients selected from in and out patients of the medical department of four University Hospitals in Seoul, Won Joo and Mok Po city. Data was collected from Sep. 18, to Oct. 15, 1984. The measurement tool was the questionaire that developed by the investigator from the literature review based on Health Belief Model. The data Collection was done by interview. Analysis of data was done by use Mean, S.D., ANOVA, Pearson Correlation Coefficient and Stepwise Multiple Regression. The result of study were as follows: 1. The significant influencing variables on the Liver Cirrhosis Patient's Sick Role Behavior in general characteristics were Sex, Marital Status, Educational levels, Family's income and Duration after diagnosis. 2. Between the Sick Role Behavior and Health Belief Model, a) The first hypothesis that the stronger degree of Health Motivation, the higher degree of Liver Cirrhosis Patient's Sick Hole Behavior was supported (r=0.7892, p=0.0000). b) The second hypothesis that the higher degree of perceived susceptibility, the higher degree of Liver Cirrhosis Patients' Sick Role Behavior was supported (r=0.6383, p=0.0000) c) The third hypothesis that the higher degree of perceived severity, the higher degree of Liver Cirrhosis Patients' Sick Role Behavior was supported (r=0.5869, p=0.0000). d) The fourth hypothesis that the higher degree of perceived benefit, the higher degree of Liver Cirrhosis patient's Sick Role Behavior was supported (r=0.7535, p=0.0000). e) The fifth hypothesis that the lower degree of perceived barrier, the higher degree of Liver Cirrhosis Patient's Sick Role Behavior was supported(r=-9.7709, p=0.0000) f) The sixth hypothesis that the higher degree of knowledge in Disease, the higher degree of Liver Cirrhosis patients'lck Role Behavior was supported (r=0.7538, p=0.0000), g) In the correlation among variables, it was found positive correlation except that perceived barrier was negatively correlated. In the Stepwise Multiple Regression and Independent Variables, the factor“Health Motivation”could account for Sick Role Behavior in 62.28% of the Sample (F=128. 786, p<0.01). When the factor“perceived barrier”is added to this, it account for 70.38% of Sick Role Behavior (F=93.479, p <0.01) and the factor“knowledge in disease”is also included, it account for 74.78% of Sick Role Behavior (F=75.131, p <0.01). Finally, when the factor“perceived susceptibility”is included, it account for 75.03% of Sick Role Behavior (F=56.329, p <0.01).

Unlike the mean-variance approach, the stochastic dominance approach is to form a portfolio that stochastically dominates a predetermined benchmark portfolio such as KOSPI. This study is to search a set of portfolio weights for the first degree stochastic dominance with maximum expected return by managing the constraint set and the objective function separately. An algorithm was developed and tested with promising results against Korean stock market data sets.

This study was conducted to find out the degree of paternal attachment to neonate, and to identify factors affecting paternal attachment. The main purpose was to make the base data for nursing intervention to improve parternal attachment. The subjects of this study were 20 fathers whose partners have delivered premature neonate and 30 fathers whose partners have delivered normal neonate in 3 university hospitals in Seoul. Data were collected from Feb. 10 to Apr. 10 1994 by self report questionaires. The instrument for this study was based on 7 kinds of characteristics of paternal attachment by Greenberg St Morris(1974), and developed by re-searcher The statistical methods for data analysis were percentage, mean, standard deviation, 1-test, ANOVA with S.P.S.S. program. The conclusions are as follows. 1. Fathers had the high degree of paternal attachent to neonate, but were afraid of active touch. 2. The factors that affect paternal attachment were delivery odor, past experience about own father except delivery pattern, pregnancy plan, sex of nonate. 3. There were not significant correlations between paternal attachment and early visual contact frequency of father-neonate. 4. In the degree of paternal attachment, though normal neonate father showed somewhat higher result than premature neonate father, there was not statistically significant difference between two groups(t=-1.83, P=0.076). But in the character of tactail awarness there were significant differences between two groups, hence nursing interventions are needed to help the premature neonate's father bring early tactile con-tact. Pother research about factors affecting paternal attachment to neonate and high risk neonate as well as low birth weight neonate is reguired.

Characteristics of urban wanning phenomenon were studied using degree days for three big cities(Seoul, Busan, Daegu) adjacent to airport. Time variation of the cooling and heating degree days was analyzed using the daily mean air temperature data measured at the six meteorological observatory for long-term periods(25～43years). The results for the big cities are as followings: 1) It was found that the heating degree days trended to decrease from year to year. 2) The cooling degree days were nearly unchanged during the same analysis periods. 3) The number of days calling for air-heating also tended to decrease as time passes. 4) Those of air-cooling were nearly unchanged during the same time. It suggests that the change of air-heating condition owing to urbanization came in evidence in the winter season, but that of air-cooling condition was slight in the summer season. On the other hand, the long-term trends of degree days were very small in airport areas except for Kimhae airport. Hence, the gaps of degree days between big cities and rural airport areas are increasing.

Purpose: This study was to serve the sexual health education of the hysterectomy patients and to get the basic data of the nursing intervention on sexual health education. Sexual health education for the patients is an independent function as well as a professional responsibility of nurses. Method: The subjects were composed of 108 post-op patients who had undergone doing a hysterectomy 5 to 10 days previously and 101 nurses at OBGY hospitals. For data analysis, the study executed a frequency, mean, standard deviation, t-test, ANOVA, Duncan Multiple Range test and Spearman's rho correlation coefficient, in accordance with the purpose of the study using SPSS Win 10.0. Result: Mean score of the needs degree of sexual health education was 3.30 point. The need for education was highest in the sexual health promotion with education related to sexual interaction the lowest. Mean score of the nurses' teaching performance degree of sexual health education was 1.80 point. The nurses' teaching performance was highest in the sexual health promotion. There exist significant correlations between the degree of patients' educational needs and the degree of nurses' teaching performance on physiosexual(p=-.667, p<.05), psychosexual(p=.762, p<.05), sexual interaction(p=.667, p<.05) respectively. There was no significant difference on sexual health promotion(p=.359, p>.05). Conclusion: The degree of sexual health education needs of hysterectomy patients was very high. Therefore, continuous nursing education program should be developed and provided for the promotion of the performance of sexual health education as the nursing professional role.
