The purpose of this study is to inquire into the degree of health promotion activity in university students, and to find out the relationship between self-efficiency and health promotion behavior, Thus, we can offer basic data for developing an educational method or program for health promotion. For this research, data was collected from university men and women through a questionnaire from February 18 to March 20, 1998. A measuring instrument was based on lating reviews of health promotion behavior in chronic disease protection, perceived self efficiency, demographic factors, biological factors, and circumstatial factors. The content validity of the instrument was authenticated by two professors of nursing, and reliability was confirmed by 'cronbach' (${\alpha}^{\prime}$ after mortifying content through a pre-test on 30 students. 475 persons were analyzed in terms of average, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Multiple Stepwise Regression by 'SPSS-PC'. The analyzed data is as follows: 1. Higher self-efficiency, as a cognitive-perceptual factor, has a beneficial effect on health promotion behavior (r=.479, p=.000). The result of analyzing the differences among a low group, a middle group, a high group in terms of self-efficiency reveals that the relationship between self-efficiency and health promoting behavior is meaningful. 2. The degree of health promoting behavior is 3.26 out of 6. Other figuresrelating to health promoting behavior, are as follows. self-actualization area (4.62), interpersonal area (4.60), stress management area (4.01), nutrition area (3.68), responsibility of health area (3.11), liquid and cigaret area (2.85), and exercise area (2.33). 3. The degree of self-efficiency was 6.81 out of 10. Other figures relating to self-efficiency are as follows. interpersonal area (7.89), self-actualization area (7.84), liquid and cigarette area (7.72), exercise area (6.88), stress management area (6.84), responsibility of health area (6.35), and nutrition area (6.34). 4. The different lerels of health promoting behavior according to a subject's general factos are following: age (p=0.003), sex (p=0.000), health concern of parents (p= 0.000), taking health programs (p=0.007), case history of familes (p=0.048). Health promoting behavier is also positirely affeted by the following: higher age, social sciences focus, religion, living the relatives', and the higher health concerns of parents. 5. The difference of self-efficiency according to a subject's general factors is positirely affected by sex (p=.008), the health concerns of parents (p=.004), body indexes (p=.001), and the higher health concerns of parents. 6. As the result of analyzing major factors, the most powerful factor appears to be self-efficiency, 26.6% of health promoting behavior. Suggestions: 1. Results of this study point to self-efficiency as a major factor in the health promoting behavior of university students. It is crucial, therefore, to develop a health program to promote self-efficiency and to study how to promote prerention of certain diseases. 2. That health promoting behavior appears low in this study shows that health education should be taken into the university class, with a focus on the daily life of students as its goal.

The purpose of this study was to investigate the relationship between bone mineral density(BMD), body composition and life styles of female college students. The subjects were 334 students with a mean age of 21.0 years. BMDs of forearm and calcaneus were measured by dual energy X-ray absorptiometry, and body composition was measured by bioelectrical impedence analysis. The means for weight, height, and body mass index(BMI) of the subjects were 55.7 kg, 161.0 cm, 21.5 kg/$m^2$, respectively. Grouping by the BMI, 13.2% of the subjects were classified as overweight, and 11.1% of the subjects as obese group. BMD in the forearm and calcaneus were 0.390 g/$cm^2$, 0.514 g/$cm^2$. In the forearm, 58.1% and 9.6% of the subjects were classified as osteopenia and osteoporosis, respectively, and in the calcaneus, 12.0% and 0.3% of the subjects were classified as osteopenia and osteoporosis, respectively. Body weight, skeletal muscle mass, lean body mass, fat mass and BMI were positively correlated with BMDs in the forearm and calcaneus($r$=0.180~0.495, $p$ <0.01~0.001), and height, % body fat and waist-hip ratio(WHR) were positively correlated with BMDs in the calcaneus($r$=0.213~0.239, $p$ <0.001), but not in the forearm. The factors such as beginning age of cigarette smoking and alcohol drinking and exercise had significant influence on BMD($p$ <0.05; p<0.001), whereas sleeping hours, activity level, frequency of exercise, meal times, frequency of snack and fried food intake, breakfast skipping and amount of meal had not significant influence on BMD. Therefore, the acquisition of balanced body composition is necessary through the increase of fat free mass and muscle mass, not through the increase of fat mass among female college students.

This study was performed to investigate dietary habits, and to evaluate the relationship between nutritional status and certain blood parameters in premenopausal and postmenopausal women living in Daejeon. Adult Korean females(n=110) that had visited the Health Promotion Center of Eulji University Hospital were analyzed. We examined blood parameters, body composition, and life style factors such as food habits and physical activity in pre- and post-menopausal women. The collected data were then analyzed to evaluate the various items. Overall, there were no differences between the pre- and post-menopausal women for food habit score, or for intakes of energy, protein, Int, iron, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C, and calcium. However, carbohydrate intake was significantly higher in the postmenopausal women than in the premenopausal women. The Dietary Reference Intakes for Koreans(KDRIs), in terms of energy, fat, calcium, vitamin A and vitamin $B_1$, were less than 100% in both the premenopausal women and postmenopausal women. All intakes of protein, iron, vitamin $B_2$, niacin, and vitamin C satisfied the KDRIs in both groups. Finally, the postmenopausal women had higher serum fasting blood glucose, total cholesterol, LDL-cholesterol and alkaline phosphatase levels than the premenopausal women.

The aging process is multifactorial and results from the combined effects of inherited(genetic) and acquired factors including life style, food habits, physical activity, and diseases. That give rise to the various approaches in aging. We are trying to study biological changes with aging, In detail we are focused on gene and protein function accompanied by normal or abnormal aging process, especially our efforts are aimed at revealing the functional relationship of proteins in aging as a final product of gene. We expect that proteomic approach to the study of protein function involved in aging should give us variety of integrated data to understand biological changes of long lived lives, We have applied expression proteomics to rat liver bred in dietary restriction or in at libitum to elucidate the effects of food habit on aging. Expression proteomics shows us protein profile in a selected tissue or cells as a whole and gives us the information about protein expression level, posttranslational modification and degenerative modification of expressed proteins. Comparative analysis of young and old rat liver by two dimensional gels shows that gene expression of several proteins was down regulated in old rats and some protein expression level is increased with aging. Dietary restriction slows down these changes of gene expression and in some proteins there's no difference in protein expression level at same ages in comparison with rats bred in at libitum. About forty protein was identified by peptide mass fingerprint with MALDI-TOF and rest of the protein of interest is in the course of identification, Also we are trying to make mitochondrial and cytosolic proteom reference map. These suborganelle proteom map will gives us the information about low abundance proteins and cellular localization of proteins. Proteomics is a growing methodology to study biological system. High throughput qualitative and qualitative aspect of this approach will gives us large amount of integrated information and speed up our understanding about biological system

The functions of the clothing have been changed rapidly in modern society. That means people want to show oneself strongly by the clothing. In other words, the social aspect of the clothing's function which is the expression of own's personality and satisfaction one's desire is emphasized. This study is aimed at taking a look at the functions of modern clothing. The modern clothing has the various functions which are related to the changing of the social system. The result of the study are as follows: With the differentiation of society and institutionalization, the clothing is recognized as the medium which shows one's status and is restricted by people. In modern society as mass society, the system of the social position collapsed. People has the inclination to express own's consciousness, personality and existence intensely. Also, the functions of clothing became diverse. That means the clothing is influenced by the human's consciousness, a sense of values and became the medium which reflects the people's life. This change of the costume means the clothing focus on the functional factor of the free-style clothing getting out of rational value. Therefore, the change of clothing is not the change of the design but the change of value of the clothing, one's way of thinking about the clothing, the change of human life in whole society and the culture. With the changing way of life, the change of the clothing has the system in which the design changes. Therefore, I found that the we have to take a look not the change of the factors which influence the fashion but the functions of the clothing itself.

The purpose of this study was to investigate dietary habits and food compliance in stroke patients. One-hundred sixty eight elderly stroke patients and 97 young patients with first -ever stroke admitted to Asan Medical Center between 1994 and 1998 were studied. Using a structured interview, we assessed food intake. food consumption frequency and compliance to low salt, low meat hight fish and high fruit and vegetable diets. These results were analyzed with X$^2$, t-tests, and analysis of variance (ANOVA) using the SAS package program. Salted food intake and cholesterol-containing food frequency were increased whereas frequency of fruits and vegetables intake was decreased in young stroke patients compared to the elderly. Meat intake and cholesterol-containing food frequency were increased in the males compared to the females in elderly stroke patients. and fish intake and cholesterol-containing food frequency were higher in the males than the females in the young. In patients with high economic status, frequency of fruits and vegetables was elevated. Also compliance the low meat and high fruit and vegetable diet in young patients was lower than that in the elderly. When the life-style risk factors influencing the food intake of frequency of fruits and vegetables was affected by education in young stroke patients. In elderly stroke patients, meat intake frequency of cholesterol-containing foods and fruits and vegetables were influenced by sex and /or income. Our results suggest that dietary intake of salt meat ,cholesterol-containing foods. fruits and vegetables in stroke patients may vary with age, sex the presence of risk factors or economic status therefore guidelines and nutrition education should by formulated to prevent stroke recurrence based on dietary habits and risk factors of individual patients.
