This study was conducted to find the powerful free radical scavenging effect in methanol extracts from 35 kinds of Korean medicinal plants obtained from the Plant Extract Bank as natural plant products. Antioxidant activity of the plant extracts was determined by measuring the scavenging effect of 1,1-diphenyl-2-picryl hydrazyl radical (DPPH). In the screening of plant extracts tested, at 200 ppm level, almost all plantex tracts showed significantly high antionidant activity. In the reinvestigation of 15 kinds of Korean medicinal plants at 50 ppm level selected as good sources with good free radical scavenging effect at 200 ppm level, the DPPH scavenging effects were similar to those of L-ascorbic acid in whole plant extract of Fragaria yezoensis (90.4％), in the plant stems and roots extract of Gingko biloba, and the leaves extract of Rhododendron mucronulatum var. ciliatum (90％). The fruits extract of Cornus officinalis showed the strongest antioxidant activity (95％). These results suggest that the methanol extracts from Korean medicinal plants can be a potential source of antioxidants that can be used to control oxidative stress in the body, But further study is needed to measure their safety for consumption

The proportion of the elderly in rural area(21.7％) is four times more than that of the urban area (5.4％) in Korea. With this rapid aging of the population in rural Korea there has been growing concern about the quality of life of rural elderly. Compare to urban elderly, rural elderly experience many disadvantages, especially in terms of limited offering of social/educational programs. Their social/educational needs are rarely assessed and there are few programs geared to the needs of rural elderly. In this regard, this study aims (1) to identify education and activity program needs of the rural elderly related to three dimensions: Family life, Farming life, and Community activities and (2) to develop education and activity programs for the rural elderly based on the needs assessment. For this purpose, data are gathered from 413 rural elderly and 110 community welfare specialists, using a structured questionaire. The statistical methods used for data analysis are descriptive statistics, cross tables with SPSS wins 10.0 program. The major findings of this study are as follows: Majority(94.1％) of the rural elderly wants to participate in diverse social/educational programs. They want to have programs dealing with 'relationship enhancement with children', 'nutrition', 'health and care', 'farming skill', 'gardening', 'volunteering', etc. Based on these results, we develop eight types of education program and four types of activity program, according to the priority of their needs in each dimension. There are four sessions of Family life program, and four sessions of Community activities program. The effect of these programs will be evaluated by taking pretest and protest in local basis.

The characteristics of social and cultural life in agricultural regions in Korea encompass several positive external effects: quality of food services, awareness of environmental conservation, aesthetic enjoyment of nature and so on. The objectives of this study were (1) to measure the awareness among Korean youth of the benefits of rural life; (2) to delineate the differences between rural and urban youth; and (3) to promote an awareness of the importance of the social benefits of living in the country. To fulfill these purposes, a field survey method was used. The subjects were 211 third grade students from middle schools in rural and urban regions in Korea. The statistical methods used for this data included frequencies, percentages, 1-tests, etc. The study generatedconclusive findings about viewpoints toward the natural environment, urban and rural social culture, and perceptions of economic status. It showed significant differences between rural and urban youth's awareness of ideas such as'green field supply','labor power supply'and 'biodiversity conservation'.

The purpose of this study was to set related variables for leadership measurement in the leader of a community organization as an effort to Community development constantly. Therefore, in this study, first, various theories on leadership were reviewed. Second, approaches and variable relationships were reviewed by leadership theory study. Third, leadership measurement variables were set based on Bass's Transformational theory, one of new trend theory, to measure the leadership of the community organization leader. As a follow up, clear and scientific analysis, through empirical analysis, based on the variables set in this study will be made to measure leadership of a community organization after creating investigation tools based on the variables set in this study A literature study was mainly used. 'Human Behavior' by Dr Han-geom Lee, 'Leadership Theory' by Eung-seop Shin, many other related books, articles of the Human Relation Organization Association, and theses and Bass's writings. Major findings of this study, through the literature study, were as follows. As conventional leadership theories, characteristics theory, behavior theory and situational leadership theory were proposed. First, characteristics theory searches the characteristics of an effective leader. It proposes that effective leaders and ineffective leaders have different characteristics, respectively. Therefore, it proposes to study the leader's characteristics. However, there is not a flexed definition for leader's characteristics. Scholars make different definition on leader's characteristics, and they are very subjective. Thus it cannot be a valid theory. Second, behavior theory describes how the leader behaves to his fellows. It studies leader's behavior focusing on what type and what combination is the most effective in all situations. However, it has weakness in that it focuses on a leader's behavior only, and ignores the situational features. Third, situational theory describes the relationship between leadership type and situation. It suggests that there is not a single leadership style that can suit all situations. It emphasizes the relationship between leadership type and situation. Although situational theory considers more variables than characteristics theory or behavior theory, it also sees situations as static and flxed. Although Fiedler's theory tried to comply with situations, he did not analyze interactions between a leader and his fellows.

A meaningful difference was showed in 4 areas'to try a new trend, impulsive buying at the store display, for a change of mood, for stylish appearance'in the purchase motivations for clothing depending on the monthly expense for clothing, in 2 areas'brand, trendy fashion'in evaluation criteria for clothing depending on the monthly expense for clothing, in 3 areas 'after service, hospitality of sales person, brand awareness' in the evaluation criteria for stores depending on the monthly expense for clothing, And Respondents of a high expense group for clothing showed higher means compared to a low expense group for clothing in all areas. A significant difference was showed among groups regarding preferred stores based on the monthly expense on clothing.

The purpose of this study was to compare the dietary behavior of middle school and high school students who had working mothers with students whose mothers were not employed. Self-reports on their dietary behavior and one-day dietary records were obtained from 396 middle school students and 364 high school students using anonymous questionnaires. The results were summarized as follows; the students with working mothers were more likely to not to eat properly and their dietary behavior was generally inadequate, showing a greater irregularity for meals, more of a tendency to skip breakfast, less diversity of food intake, and a higher incidence of drinking and smoking. One-day dietary records obtained by 24k recall methods showed less diverse food intake and a higher rate of skipped meals in students with working mothers. Drinking and smoking were more prevalent among middle school students whose mothers were working than among those students with unemployed mothers, but in the case of high school student the difference was not significant. With more and more housewives seeking jobs, more attention needs to be given to the dietary and nutritional intake of their children, especially among middle school students. High school students seem to be less affected than middle school students by their mother's employment.

This study is to investigate the effect of dietary mixed protein and L-carnitine supplementation on lipid metabolism in the rats fed high fat diet. Six experimental groups were organized and each group had eight Sprague-Dawley male white rats with the initial weight of around 180g. The six experimental groups were CO(supplemented with casein), CC(supplementedwith casein and cartinine), ISO(supplemented with isolated soy protein), ISC(supplemented with isolated soy protein and cartinine), CIM(supplemented with casein and isolated soy protein), and CIC(supplemented with casein, isolated soy protein and cartinine). Each group was supplemented with the experimental diet for four weeks, and carnitine contained 3efo of the diet. The results were as follows; 1. There was no significant difference in food intake among the experimental groups. The weight increased more significantly in the group supplemented with the mixed protein than in the group supplemented with casein(p<0.05).2. There was weight reduction effect by the supplementation of carnitine(p<0.05), however no weight reduction effect by the supplementation of carnitine was observed in the group supplemented with the mixed protein and isolated soy protein. 3. Food efficiency was lower in the group supplemented with the mixed protein than in the group supplemented with casein (p<0.05), however it was similar in the group supplemented with isolated soy protein.4. Serum total lipid and se겨m total cholesterol were lower in the group supplemented with mixed protein than in the group supplemented with casein(p<0.05). 5. There was no significant difference of serum triglyceride, HDL-cholesterol, and LDL-cholesterol among the experimental groups. 6. Liver triglyceride was the highest in the group supplemented with mixed protein (p<0.05), and there was no significant difference of liver total lipid and total cholesterol among the experimental groups. 7. In the groups supplemented with mixed protein, the level of liver TBARS showed the lowest when casein was supplemented(p<0.05), and there was no significant difference of GSH-Px activities among the experimental groups. In summary, when mixed protein was supplemented to the rats weight gain and food efficiency were similar with those in the group supplemented with isolated soy protein, however they were lower than those in the group supplemented with casein. The effect of carnitine on weight was not observed in the group supplemented with mixed protein and isolated soy protein, however it was observed in the group supplemented with casein. Serum Total lipid and total cholesterol were lower than those in the group supplemented with casein. Liver total triglyceride was high in the group supplemented with mixed protein, and the antioxidant effect was observed in the group supplemented with mixed protein.

This study examines the different degrees of sexual awareness shown among high school girls in urban and rural areas. The analysis was carried out by dividing these students into urban and rural groups. A questionnaire of 51 questions based on previous studies and a review of the literature was prepared for students in the two groups after two preliminary surveys, a reliability test, and correlation. There were 721 copies of the questionnaire in total which were distributed to students of 2 urban and 4 rural girls' high schools. The analysis of the results was carried out using by means of SPSS 10.0, and it became clear that girl's students' viewpoints toward sex, the actual circumstances of their acquaintance of the opposite sex, the access to information about sex, the content of current sex education at school and the ideal type of sex education, tended to show differences between the two groups. This study showed that the standardized and uniform content and methods of current sex education in public schools does not work properly. Sex education at schools in South Korea has reached a limit of their effectiveness to a point where research into more effective sex education is required.

The objective of this study was to analyze the evaluation of the rural resident's on their community at view of community life satisfaction. The specific purposes of this study were to identify the degrees of community life satisfaction, consciousness of rural community according to the individual variables.

Local fairs are often part of the economic development strategy of rural areas. This study aims to find out marketing strategies for promoting the sales of regional specialty products through local festivals in rural Korea. The data were collected in late 2003 (from a sample of interviews and surveys from 351 visitors. The data were analyzed using the SPSS computer program. The results were as follows; First, the factors that visitors were considered in purchasing were quality (49.5％), commemorative value (36.9％), and reliability (33.0％). And the top reasons cited for not buying were lack of distinction (45.1％) and high prices (26.6％). The discount rates expected in markets was 16.8％. Second, 49.8％ of visitors has spent over 10,000 won and their purchase pattern has been for themselves and their family. Third, the public organizations for certi(ication for visitors were the National Agricultural Cooperative Fedration (37.9％) and the Ministry of Agriculture and Forestry (MAF) (22.5％). In conclusion, it was important for local stakeholders to provide more locally-manufactured, seasonal and traditional food, and to plan more locally characteristic events for their fairs. Further recommendations have included having a guide showing pricing and quality standards for products bought at rural fairs, developing product ideas for inducing impulse purchases, active promotion and marketing at event sites, and setting a standard system of warranties on products under the certification of the local authorities and with the financial support of the MAF Such recommendations were aimed at increasing the sale of traditional and regional specialty products at local festivals.

Due to the changes of modern society, alternative types of nuclear family so called as commuting family have appeared. Also, with the increase of women's economic participation and their needs of self-actualization, dual-career commuting family have increased. The purpose of this study was to investigate whether there is any difference between the traditional commuting family and dual-career commuting family in terms of family relation, types of child-care and social support. Also, this study qualitatively analysed parenting-guilty of the mothers of commuting family. One eight seven mothers of three to eight year-old participated the survey. The main results were as follows : (1) In case of traditional commuting family, children cohabit with the mother and usually fathers move between two houses. But among the dual-career commuting family, there are some children who cohabit with the father and some mothers who move. Dual-career commuting family relied on the more types of child-care than traditional commuting family. (2) While traditional commuting family get more support for child-rearing from the husband's family of origin than dual-career commuting family, wife's family of origin provide more support to the dual-career commuting family. The more support the husband's family of origin provide, the more stress both types of commuting family experience. However, there was no significant relationship between the support from the wife's family of origin or friends and the stress of the mothers of both types of commuting family. (3) Mothers of two types of commuting families were different regarding the motives of parenting-guilty Difficulty of caring the children for their job as well as father-absentness makes mothers of dual-career commuting family feel parenting-guilty more.

The purpose of this study is to present a plan to activate the production and consumption of environmently friendly agricultural products through an analysis on the understanding degree, the level and inclination of consumption, the satisfaction degree of consumption, and the comprehension degree of production and circulation process of the environmently friendly agricultural products. 1 reviewed the literature and did survey In this study. The results are as follows : (1) As a result of an analysis on the understanding degree of the environmently friendly agricultural products, it is shown to get 6.37 points out of 10 and also, there is a difference between age, educational background, and income level. (2) In the case of research on the method to distinguish the environmently friendly agricultural products from others, it is proved that consumers have a strong faith on quality guarantee marks and there is a difference between gender, income level, and consumption period. (3) It is also shown that consumers purchase environmently friendly agricultural products for the family member's health in the survey on the motivation for purchasing them. And also, there is a difference between men and women. (4) The result of the survey on the consumption scale of the environmently friendly agricultural products shows that 94 people(60.3％) spend more than 50％ of their gloss foodstuffs cost purchasing them and 20 people(12.8％) spend 30-50％. (5) In the survey on the amount and the frequency of the purchasing items of the envirounently friendly agricultural products, respondents count livestock products mostly in amount while point out main cereals and a kinds of soy and pastes in frequency. (6) Consumers ask that the price of environmently friendly agricultural products is a little expensive or reasonable and there is no differences between individual groups. (7) In the case of the purchase of foreign environmently friendly agricultural products, there are more people who want to purchase domestic ones than those who want foreign ones. Therefore, it is shown that environmently friendly agricultural products have a counterpower after the market-open to import. (8) As a result of the analysis on the quality of environmently friendly agricultural products, it is proved that they have better quality than general agricultural products and also, it is found out that women feel larger differences than men in quality. (9) In the analysis on the satisfaction degree of the environmently friendly agricultural products, it is proved that respondents trust the safety and nutrition of them whereas they are not satisfied with the external shape of them. (10) It is analyzed that tile conversion of consumer's consciousness is the most critical factor for development of environmently friendly agriculture. (11) The factors to activate the consumption of environmently friendly agricultural products are proved in order of the enlargement of direct transaction, the conversion of consumer's consciousness, the easiness of purchase, activating consumers'unions, and publicity.

Food is very important for human being. It is not easy for us to enjoy good life because the situation of food is not good in Korea. The self-sufficient food rate is very low and most of food which we take was produced by industrial agriculture. Food of this kind has some problems with respect to the health of consumer, agriculture, environment and community. In order to secure the true food which is safe and environmentally sound, producers, consumers and community have to work together. Producers must engage in environmental agriculture. They must produce the true food and need to know regional consumers. Consumers must pay attention to the regional agriculture and must participate the production of true food. Local government must open farmers' markets for direct marketing between farmers and consumers. NGOs should educate and organize the producers and consumers.
