The primary purpose of this study was to identify factors affecting health promoting lifestyles of college students on the basis of Pender's Health Promotion Model. The subjects were 1,159 students of one university in Seoul. These data were collected by self reporting questionnaire from April 19 to May 3, 1993. This study examined health promoting lifestyles, cognitive-percep-tual factors: perceived health status, perceived importance of health, health locus of control, and health conception, and modifying factors: sex, grade, major, residence type, and attendance at a health care course. The instruments used in this study were Health Promoting Lifestyle Profile by Walker et al. (1987), Health Value Scale by Wallston et al. (1976), Health Locus of Control by Wallston et al. (1978), and Health Conception Scale by Laffrey(1986). The data were analyzed by Cronbach's $\alpha$, mean, standard deviation, percentage, t-test, ANOVA, Pearson's Correlation Coefficient, and Stepwise Multiple Regression with SPSS PC+ Program. The results were as follows : 1. The means of health promoting lifestyles revealed total 3.33, self actualization 3.74, health responsibility 2.72, exercise 2.80, nutrition 3.55, interpersonal surpport 3.76, and stress management 2.96. Interpersonal support showed the highest score and health responsibility showed the lowest score. 2. No significant differences between sex, grade, major, and residence type, and health promoting lifestyles Were founded(p>.05). Attendants at a health care course showed a significant higher score than nonattendants (p<.001). Male showed a significant higher score in exercise subscale, female showed significant higher scores in health responsibility, nutrition, interpersonal support, stress management subscales(p<.001), residence type showed a significant difference in nutrition subscale(p<.001). 3. No significant differences between perceived health status and sex, grade, major, residence type, and attendance at a health care course were founded(p>.05). Perceived importance of health showed no differences among sex, grade, major, and residence type(p>.05), showed only in attendance at a health care course (p<.001). Attendants at a health care course showed a significant higher score than nonattendants(p<.001). No significant differences between health conception and sex, grade, major, and residence type were founded (p>.05), only significant difference between health conception and attendance at a health care course was founded(p<.05). Nonattendants showed a significant higher score in clinical health conception, attendants showed a significant higher score in wellbeing health conception(p<.05). 4. A significant positive correlation between health promoting lifestyles and perceived health status was founded(r=.2415, p<.001). A significant positive correlation between health promoting lifestyles and perceived importance of health was founded (r=.1475, p<.001). The health promoting lifestyles revealed significant positive correlations in internal and powerful others locus of control (r=.3187, p<.001: r=.1475, p<.001), but revealed a significant negative correlation in chance locus of control(r=-.997, p<.001). A significant positive correlation between health promoting lifestyles and clinical health conception and wellbeing health conception were founded (r=.1241, p<.001 : r=.3047, p<.001). 5. Perceived health status was the highest factor predicting health promoting lifestyles of college students(R=.3415, $R^2=11.62$). Perceived health' status, perceived improtance of health, internal locus of control, wellbeing health conception, powerful others locus of control accounted for 28.19% in health promoting lifestyle patterns. In conclusion, college students who reported more helath promoting lifestyles evaluated their health positively, perceived importance of health highly, perceived their health as affected by theirselves, powerful others but not by chance or luck, and accepted health as high level wellness rather than merely the absence of illness. Those who attending at a health care course had healthier lifestyle patterns. And attendance at a health care course had significant. correlations in these cognitive-perceptual factors. Further studies are required to identify reasons of attending a health care course, and to compare health promoting lifestyles pre-post attending a course related to health care.

The purpose of this study is to investigate the perception of middle school students about Home Economics course especially in the area of Food and Nutrition. For this purpose anempirical survey was conducted using structured questionnaire from 482 students in the 2nd grade of middle school. The questionnaire contained questions about the general concept of home Economics course and general concept and the degree of the perceived need of Food and Nutrition part of the course. The data of analysis are frqequency percentile mean standard-deviation chi-square one-way ANOVA t-test and Scheff-test. The major findings of this study are as follows. The major findings of this study are as follows. First students show a tendency to perceive Home Economics education is $\ulcorner$related with ethics of human life for both sexes$\lrcorner$which is stronger in girls than in boys. Boys had a tendency to perceive that Home economics is related with $\ulcorner$home making skills in food clothing housings etc.$\lrcorner$or $\ulcorner$for girls and women only $\lrcorner$which is weaker in girls. Second students also show a tendency to perceive Home Economics is important and to agree that Home Economics must be taught to both sexes. This tendency is stronger in girls than in boys, Third students show a tendency to perceive that food and Nutrition part is related with $\ulcorner$meeting problems in food choices and nutrition$\lrcorner$which is stronger in girls than in boys. Fourth girls are more interested in Food and Nutrition part than the other parts and likely to practice what they learned in Food and Nutrition part of their 1st grade and became to pay attention to their eating patterns. These tendencies are weaker in boys.

Objectives: Many female college students today control their lifestyle not for the purpose to promote their health but to maintain slender figures. The purpose of this study was to explore and describe the lifestyle of female college students from their own perspectives. Methods: Data was collected through interviews of 25 female students and was analyzed by using Colaizzi's descriptive phenomenology(1978). The phenomenon of interest was described, followed by collecting participants' descriptions of the phenomenon and extracting concepts from significant statements. These concepts were then organized into thematic clusters, followed by exhaustive descriptions into which data was applied to extract the final categories. Results: The results were deduced into 226 re-statements, 38 constructed meanings, 23 themes, 11 theme clusters, and 5 categories. The five categories include 'Increased interest in physical health,' 'Selective dietary patterns influenced by lifestyle,' 'Lifestyle formed by social adaptation,' 'Health complications caused by self-body images,' 'Engages in healthy dietary behavior'. Conclusion: This study described the experiences of female college students' lifestyles after completing a course in health promotion. These findings have important implications on health education for college students which should be considered in developing health education programs in preparation for adult years of life.

This study aims to analyze marital satisfaction over the family life course and to find its determinants in Korea and Japan. The data for this study came from nationwide representative sample surveys on family in these two countries including 5,308 Korean and 4,920 Japanese men and women living with their spouses. In order to see the cultural difference and similarity in marital relations, the effects of education, income, employment, marriage gradients (normative patterns between the spouses), family stress, and quality of conjugal interactions on Korean and Japanese couples' marital satisfaction were examined. It was found that the marital satisfaction showed a U-shape pattern for both Korean and Japanese couples. In both countries husbands tend to have higher marital satisfaction than wives over the entire life course. The most important determinants of Korean and Japanese couples' marital satisfaction are good qualities of conjugal interactions including deep trust and concerns for spouse and sex life satisfaction. For Korean couples good conjugal interactions is better predictor of marital satisfaction than sex life, while for Japanese couples sex life is more important determinant of marital satisfaction.

It is estimated that the elderly will constitute 24.3% of the entire Korean population in 2030, when about 7,125,000 baby boomers reach retirement age. Therefore, this aging phenomenon might be the most urgent issue facing Korean society. The baby boom generation shows a strong tendency to dispose of existing residences or move into new housing after retirement, thereby exerting enormous impacts on social and economic sectors as well as the housing market. Against this backdrop, this study aims to identify both factors and patterns behind baby boomer retirees' post-retirement housing transfer trends. To this end, a survey is undertaken here with respect to those baby boomers living in Gangnam-gu and Seocho-gu with actual housing transfer plans in the foreseeable future, and who can act as a practical consumer group for the future housing market. This study verifies baby boomers' diverse preferences for housing type. Their preference for apartment houses still remains high in every situation, and this has significant implications for changed preferences of other housing types considering that most of the survey respondents currently reside in apartment houses. According to the survey, there are more than 80 kinds of baby boomers' housing transfer patterns, which demonstrates that more than half of the survey respondents pursue different housing mobility plans. When it comes to the factors behind their housing selection, the baby boom generation shows a strong preference for physical factors. However, environmental and psychological factors gain more momentum under unfavorable circumstances, while social factors play a decisive role in their housing selection in categories such as 'couple/deteriorating health' and 'single/healthy'.

The aim of this study was to investigate expression patterns of the prolactin (PRL) and c-fos genes by 17$\beta$-estradiol (17$\beta$-E) and stress in the mouse pituitary. In the pituitary, the levels of PRL mRNA were found high with some fluctuation at 30, 50, and 90 min whereas the levels of PRL mRNA were low at 120 min when ovariectomized female mice were injected with 17$\beta$-E or vehicle. PRL mRNA levels began to increase again at 4 h and remained high up to 24 h only in the 17$\beta$-E- treated mice. The overall changes in c-fos mRNA by 17$\beta$-E were very similar to those in PRL mRNA in the pituitary. Subsequent study revealed that these high initial levels of PRL and c-fos mRNAs were caused by stress during Injection, not by 17$\beta$-E, since vehicle injection alone into the ovariectomized mice could increase the levels of PRL and c-fos mRNAs. The stress-induced elevations of PRL and c-fos mRNAs were inhibited by bromocriptin, a dopamine agonist, suggesting that the dopaminergic system is involved in the action route of injection stress. In addition, the induced levels of c-fos mRNA by 17$\beta$-E and stress in the pituitary were very low compared with those in the uterus. The time course changes in c-fos mRNA level were different between the pituitary and uterus. Taken together, these data indicate that PRL and c-tos gene expression in the pituitary are regulated by 17$\beta$-E and stress in a parallel manner, supporting the notion that c-Fos plays a role in regulation of PRL gene expression.

The purpose of this study is to develop Family Life Education program for Marital education in Korea. In order to realize the about research purpose, this study is divided into three sections. First, nature conception and contents f Family Life Education, second, patterns and models for Family Life Education Program in USA and Korea, and Third, the future of Family Life Education. Family Life Education (FLE) is an education originated in reaction to changing social conditions, industrialization and urbanization, it deals with the perceived inadequacies of families to cope with these changes, thereby reduction social problems involved with, and improving family life. With and assumption that the studies about FLE have not been so active in Korea, the present thesis examines the FLE in Korea. The necessity of marital education in Korea Is based upon the theories of FLE in the United States of America. Also, it atempts to formulate a tentative plan for the promotion of a FLE program in Korea. The concept of FLE in Korea was manifested in the social educational law and life-span education. specified as 4th among ten presidential regulations. It is defined as " the Life-span developmental education to enhance the quality of human life, to solve family problems, to develop an individual's potentiality and to strengthen the family relations. of the FLE programs, the marital education is considered one of the furcial wubjects becaused it is the core of the family life. With this premise, FLE tries to wupport the healthy mrital relations. subsequently helping to explore the family potentiality and to strengthen family ties. The objects of the FLE program are unmarried, pre-marred , and married persons. For the married persons, the FLE program should be arranged in accordance with their rrital status divided by the family life cycle so that they may prevent possible family problems at each stage of the family life. Also, to prevent the problems occurred in the course of carrying out family functions, the FLE program should be provided with on the basis of a family unit, thereby improving the quality of the family functions. The FLE is to hep persons begin smoothly the adaption process for a successful marital relations. For the FLE to be practised more widely systematically, research on family education--that is basic study, research and production and evaluation or the FLE to be carried out by research institute wholly responsible for it-- should be done first.

During the course of evolution, animals encountered the harmful effects of fungi, which are strong pathogens. Therefore, they have developed powerful mechanisms to protect themselves against these fungal invaders. ${\beta}$-Glucans are glucose polymers of a linear ${\beta}$(1,3)-glucan backbone with ${\beta}$(1,6)-linked side chains. The immunostimulatory and antitumor activities of ${\beta}$-glucans have been reported; however, their mechanisms have only begun to be elucidated. Fungal and particulate ${\beta}$-glucans, despite their large size, can be taken up by the M cells of Peyer's patches, and interact with macrophages or dendritic cells (DCs) and activate systemic immune responses to overcome the fungal infection. The sampled ${\beta}$-glucans function as pathogen-associated molecular patterns (PAMPs) and are recognized by pattern recognition receptors (PRRs) on innate immune cells. Dectin-1 receptor systems have been incorporated as the PRRs of ${\beta}$-glucans in the innate immune cells of higher animal systems, which function on the front line against fungal infection, and have been exploited in cancer treatments to enhance systemic immune function. Dectin-1 on macrophages and DCs performs dual functions: internalization of ${\beta}$-glucan-containing particles and transmittance of its signals into the nucleus. This review will depict in detail how the physicochemical nature of ${\beta}$-glucan contributes to its immunostimulating effect in hosts and the potential uses of ${\beta}$-glucan by elucidating the dectin-1 signal transduction pathway. The elucidation of ${\beta}$-glucan and its signaling pathway will undoubtedly open a new research area on its potential therapeutic applications, including as immunostimulants for antifungal and anti-cancer regimens.

Obesity during childhood is a dominant risk factor for noncommunicable diseases (NCDs), and is itself considered a disease that needs to be treated. Recently, the growth in childhood obesity in Korea has become stagnant; however, two in every ten children are still overweight. In addition, 60% or more of overweight children have at least one metabolic syndrome risk factor. Thus, childhood obesity should be controlled through lifestyle modification. This paper reviews studies of the modifiable risk factors of obesity in Korean children. According to the life-course approach, preschool-aged children (<5 years) are influenced by their parents rather than individual habits because they are under mostly parental care. Elementary school-aged children (6 to 11 years) are affected by overlapping individual and parental effects. This may mean that the establishment of individual behavior patterns begins during this period. The conditions of poor eating habits such as skipping meals, eating out, and high fat intake, along with low physical activity, facilitate increased obesity among adolescents (12 to 18 years). Notably, adolescent girls show high rates of both underweight and obesity, which may lead to the development of NCDs in their offspring. Therefore, the problem of NCDs is no longer limited to adults, but is also prevalent among children. In addition, early intervention offers cost-effective opportunities for preventing NCDs. Thus, children need primary consideration, adequate monitoring, diagnosis, and treatment to reduce the burden of NCDs later in adulthood.

To investigate the causes of Korea's growth slowdown over the past thirty years, we estimate the contributions of major developmental factors, including i) demographic factors (changes in population growth and workforce age due to the demographic transition), ii) quality-of-life-related choice factors (changes in working hours, education, and the female employment rate), iii) structural change, and iv) the effects of productivity catch-up. Our estimates show that these four groups of factors account for approximately 90 percent of the growth slowdown, with demographic factors contributing approximately 30 percent and the other three groups of factors each contributing about 20 percent. We also show that the same factors explain most of Korea's high growth in the 1980s. These results suggest that Korea's growth slowdown is basically a consequence of its successful economic development and that the high growth and subsequent slowdown can be regarded as a single process. In addition, given that the factors examined here exhibit similar patterns of change in the course of economic development of most countries, we think that our estimation results of the relationship between economic development and changes in economic growth trends could have more general implications that go beyond Korea's experience.
