This study aims to understand why public information systems in agricultural fields have shown lower performances than other industrialized fields and industries and how these problems would be fixed and overcame. To accomplish this research purpose, this study would overview the previous studies on developing agricultural information systems in public sectors and would find out meaningful and considerable factors. This study would accept the methodologies of literature review and systems thinking approaches to understand the relationships among the found factors and to suggest the conceptual research model. Agricultural information system should take care to reduce implement and maintenance costs to reduce the negative relationships between costs and expected service value and between expected service value to perceived service value. Also, it should be understood that impersonal response would reduce the eager to use the services, so the government sectors should consider positively to adopt the concept of CRM even though the government sectors traditionally have ignored its necessity. The failure of public information systems/services may be caused not only by lack of the contents but also by the failure of the persistent post management.

The study was undertaken to assess the degree to which subjects were compliant with a specific metabolic diet in a controlled outpatient feeding study. The study consisted of a two-week control period in which subjects consumed a control diet consisting of 38-40% fat, 18-20% protein, 40-42% carbohydrate, followed by a three-week experimental period during which each subject consumed the control diet plus one of the four fiber supplements(20g/4ay) assigned on a random basis on the trust day. All meals were prepared and eaten in a metabolic feeding laboratory, with the exception of Saturday and Sunday meals that were packed for take-out. Fifty-seven healthy adult men, aged 18-65 years participated in the study. Dietary compliance index(CI) defined as the percent deviation of actual consumption from the prescribed food's and unconsumed prepared foods. The CI reflected the additional 'non-prescribed foods' and unconsumed 'prescribed foods'. A CI was calculated for all subjects. A CI of 5% or more was defined as poor compliance. Overall, dietary compliance was substantially improved for the entire group over the course of the study. Significant increase in compliance far energy and macronutrient intake occurred between the baseline and experimental periods. Within a non-obese group, dietary compliance fir energy improved from 5.5% to 3.3% by the end of the study(week 1vs week 5, respectively, p<0.05). However, between non-obese and obese group, dietary compliance was not different. (Korean J Nutrition 31(5) : 957-964, 1998)

It is said that a mode of dietary behavior changes together with socioeconomic and cultural transformation. Formation of dietary habit of pre-school children influences upon direction of this changes, specially. So, this study was planned to analyst the dietary pattern of pre-school children. A survey was carried out for 3 days of 28 pre-school children with a mean age of 4 years and 3 months. Each child's matter wrote dietary pattern and kinds of food as staple, subsidiary and snack. The results showed that; (1) the average meal frequency a day was 3.1 and interval between meal was 5.1 hours (for breakfast to lunch & lunch to supper) and 12.6 hours (for supper to breakfast), (2) there were 27 different kinds of foods as staple and cereal products consumed the most among those, and 82 different kinds of foods as subsidiary and KIMCHI products were eaten the most rating, (3) the average snack frequency a day was 5.0. There were 76 different kinds of foods as snack, among them cold drink was the best. The present observation suggested that pre-school children had a tendency to take meat regularly, but snack very irregularly, and kinds of foods taken as staple, subsidiary and snack didn't keep the nutritional balance. Parent's concern about dietary behavior of their children is demanded more than ever.

Kimchi refrigerator is a specific refrigerator for Kimchi, Korean traditional fermented food. It has been fast popularized since it was developed about ten years ago. In this study, a survey was conducted with 103 female voluntary respondents to understand the customer satisfaction of the Kimchi refrigerator in the aspect of physical use. The respondents showed a high satisfaction for the use of refrigerators. It was, however, shown that they felt highly uncomfortable in using the refrigerator. In particular, the high discomfort was related to the fact that the customer should bend her torso very much to put Kimchi containers into the refrigerator, take them out of it, or clean its inside. Seventy-five percent of the respondents reported the experience of body-part pains and 58.4% of them reported pain experience in the back. It is presumed that these results are highly correlated to the top-cover design of the refrigerator, which is the most popular type to improve its performance of maintaining proper temperature. Therefore, the developers should consider these usability problems related to the refrigerator and try to enhance its usability by adopting ergonomics in the design stage.

In Korea, the position of health among the sectors of everyday life lies behind the others. The inhabitants don't consider health so important and immediate as food and shelter. Primarily, it seemed more important for them to eat something and to educate their children than to secure health. Under this situations we must take into consideration their health status and health problems in terms of the social system. Health cannot be maintaned by itself. It inter acts with a set of social conditions such as income, knowledge about health, health institution, health insurance, social class, culture and etc. But the community health projects which have carried out in Korea since the beginning of 1970s focused mainly on the medical care and medical delivery itself regardless the background of health care. According to the existing results of socio-epidemiological and medico-sociological researches, a set of social conditions has a great effect on the inhabitants' health status and health care. So, such conditions will be considered primarily in Korea University Health Project. This paper is prepared as a preliminary step for such a program. In this paper we mainly inquired into the relationship between health and the attitudes of inhabitants.

Garlic is one of the most popular seasoning bulb vegetables in Korea and is the most commonly used food ingredient. However, the cultivation areas are decreasing every year as the price drops due to imported garlic, and labor is insufficient to produce garlic by conventional methods. Cultivation requires various tasks until garlic is harvested. Seeding is one of the important and laborious tasks; thus, mechanization is necessary. When seeding garlic, the sprout should face upwards; otherwise, it may rot or produce poor quality garlic. This study investigated the extent of growth of northern- and southern-type garlic in eight different positions. The results show when the roots were not planted properly, the stems were weak, and the garlic bulbs were small. A simple garlic planter was manufactured with a crank-press mechanism to plant garlic in an upright position. Using this machine, a three-fold experiment was carried out with 100 strips of garlic. The test results showed that 99.4% of the planted garlic strips were positioned upright or close to being upright, and 0.6% failed to take root. An image processing algorithm was developed to locate the root part of the garlic, and the result showed a success rate of 81%. A future study will develop an automatic garlic upright planting system with a viewing system.

This study was aimed at comparing the dietary patterns of university female students according to their residence type. As for subjects, one hundred and twenty students of Kongju national university were chosen as a total. They were devided into three groups ; those who live in family home, or university dormitory, or self-boarding house. In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day food records and questionnaire. The result was that mean daily intakes of calcium and iron were lower than RDAs in all groups. According to residence type, subjects of family home and self-boarding seemed to have more serious problem in the nutrients mentioned above considering the proportions of less than 2/3 of RDAs. Especially, iron status was poorer than any other nutrients in the aspects of this proportion and food source. Iron was taken largely from vegetable foods which were recognized as a source of low bioavailability of iron. The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 22, 29, 30 and 19. Thus, it proved that breakfast tended to be more negligent than any other meals, and that snack was an important means to give nutrients for subjects. This meal pattern might be one of the factor for the decrease of the dietary quality. Processed foods were founded to be an important source for providing nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients intake were 30.6, 29.5 and 46.2. However, other nutrient intakes from processed foods such as vitamin and mineral were small. And processed foods which give nutrients were mainly cereal products like ra myon, bread, and milk and milk products. Consequently, processed foods seemed to be selected as a combinient substitute food which supply calorie to fill their hunger. According to the living type, dormitory students had them more frequently than any other groups. Food habit score was within the category of poor or fair. Particularly, the score of self-boarding students was the lowest of groups(p<0.05). The major dietary problems were small or overating, missing meal and irregular eating. The degree of these problems was a little different among groups(P<0.01). Nineteen kinds of food were consumed per day, and family home and self-boarding students had foods less variously than dormitory students(P<0.05). Proportions of skipping breakfast, lunch and dinner were 20.8, 12.5 and 8.3%. Accordingly, breakfast was missed more often than any other meals. And self-boarding students missed breakfast more often than any other groups. As a conclusion, subjects should take more calcium and iron, and eat diverse foods to improve their nutritional status. And it is also necessary that breakfast should be regarded more importantly, and that processed foods should be taken considering nutritional balance. In view of residence type, subjects of family home or self-boarding had more dietary problems than dormitory subjects. Thus, these results suggest that university female students might have low ability of meal management, and dietary patterns were different by their residence type. Therefore, nutrition education for them should be carried out with respect to dewelling environment.

The previous extensive in vitro studies on the antioxidative activities of a number of Korean grains, vegetables, seaweeds and mushrooms, and the various combinations of these food source exhibited a wide range of antioxidative activities, and four food mixtures composed of 5 kinds of foods (5A, 5B, 5C and 5D) were designed from 16 selective foods showing. high antioxidant effect, in vitro, to find the good combinations for the meal planning. Mixture 5B or 5C contained very high levels of total flavonoid and polyphenol, and ethanol extract from 5A, 5B or 5C showed very strong inhibitory effects against in vitro $Fe^{2+}-induced$ lipid peroxidation and ethanol extract from 5B or 5C showed remarkable DPPH radical scavenging effect and lipid peroxide-protein conjugation inhibition effect. And in vivo study was also carried out with two mixtures (5B, 5C). Powders (P5B, P5C) or ethanol extracts (E5B, E5C) of these mixtures were supplemented to Sprague-Dawley rats fed on high fat $(15\%)-high$ cholesterol $(1\%)$ semipurified diet for 5 weeks. The total antioxidant power in serum was significantly higher in P5B, P5C, E5B and E5C groups than in high fat control group, and $ascorbate-Fe^{2+}-induced$ TBARS was significantly lowered by E5B supplementation in rat liver. In liver tissue, Cu, Zn-SOD activity was significantly higher in P5B and E5B groups than in high fat control group, while catalase or GSH-peroxidase (GPx) activity was not changed by any supplementations. In kidney, Cu, Zn­SOD activity was significantly higher in P5B group than in high fat control group, while GPx activity was not changed by any supplementations. Taken together, mixture 5B and 5C showed very strong antioxidative effects both in vitro and in vivo. Therefore, the ingredient Korean foods of 5B and 5C could be recommended to take a lot together for prevention from age-related chronic diseases.
