The purpose of this study was to investigate the levels of recognition, practice and information acquisition behaviors regarding food additives of university students for development of educational programs. The data were collected from 283 students in the Yeungnam region through a self-administered questionnaire. The level of concern about food additives was intermediate. The level of checking labels for food additives when buying processed foods was not high. The main reason for not checking labels for food additives was "Buying the special brand products repeatedly". In the factor analysis for perception of food additives, three factors were categorized; effect of food additives on human health, administration and regulation of food additives, and necessity of food additives. According to regression analyses, grade, concern about food additives and perception of amount of food additives had significant effects on human health. The significant variables for administration and regulation of food additives were gender, grade, major, monthly allowance and concern about food additives. In addition, major was a significant variable for the necessity of food additives. Many respondents did not reduce intake of food additives; males did less than females. Most respondents answered they did not acquire sufficient information about food additives. Regarding needs for information content on food additives, respondents wanted information about safety of food additives the most, followed by items of labels for food additives, and ways to reduce intake of food additives.

Objectives: Rapid economic growth and industrial development in South Korea have led to a great change in dietary patterns, and the use of convenience foods has continuously increased. This study was performed to evaluate the energy and nutrient contents of convenience foods at convenience stores near the universities as a meal. Methods: Data was collected by visiting 22 convenience stores near some universities in Chungbuk and Seoul and by checking nutrition labels on convenience foods at the stores. Data of a total of 338 food items were collected, and divided into five groups according to the food categories; rice products (n=156), noodles (n=101), burger/sandwiches (n=62), Tteokbokkis (n=11), and dumplings (n=8). Further, rice products, noodles, and burger/sandwiches were divided into subcategories. Results: The proportion of calories from carbohydrates was high in the rice products and tteokbokki, while the rate of calories from fat was high in burger/sandwiches and dumplings. Among the rice products, the proportion of carbohydrate calories was high in a one-dish food, rice with soup, and triangular kimbap, while the proportion of calories from fat in lunch boxes was high. In the noodles category, ramyeon and spaghetti had a high percentage of fat calories, while udong had a high percentage of carbohydrate calories. The ratio of the calorie content in relation to the KDRIs for adults aged 19-29 years, lunch boxes provided about 1/3 of daily required energy. However, the amount of calories as one meal was not enough for other types of rice products except for lunch boxes. Ramyeon was high in calories, fat, and sodium, but low in protein content. The burger/sandwiches had a high percentage of fat and sodium. Conclusions: Our results showed several nutritional limitations of convenience meals in convenience stores according to the type of food. Therefore, college students should limit excessive intake of convenience meals on a regular basis in order to avoid unhealthy food intake patterns. Our results demonstrate the need for educating college students with regard to checking nutrition labels when choosing convenience meals in order to facilitate the selection of food items that contribute to a balanced diet.

Objectives: This study was conducted to examine the status of foodservice management, with special interest on sanitary and nutritional food service in elderly day care centers. Methods: A total of 79 employees who managed foodservice facilities in elderly day care centers were included in the survey. The contents of the questionnaire consisted of general characteristics, importance and performance of sanitary and nutrition management, the reasons for poor performance, factors necessary for improvement, and the employee's demand for support. Data analysis was conducted using the SPSS v25.0. Results: Sanitary management showed an average importance score of 4.84 ± 0.40 and a performance score of 4.70 ± 0.61 (t-value: 8.260). The item with the lowest performance score was personal sanitary management (4.58 ± 0.71). In nutrition management, the average importance score was 4.52 ± 0.68, and the performance score was 4.20 ± 1.00 (t-value: 9.609). There were significant differences between the average score of importance and performance in both areas. As a result of an Importance-Performance Analysis, items that were recognized as important but had relatively low performance was "personal hygiene", "ventilation" and "food storage". Also in the nutritional management area, "menu planning for disease management" and "checking the saltiness in the soup" etc. had very low performance with low importance recognition. The items shown in the "low priority" quadrant were those that required professional management skills. In the areas that demanded support in foodservice management, education about sanitary and safe institutional food service had the highest score (4.42 ± 0.74), and all other items showed a demand of 4 points or more. Conclusions: Foodservice managers recognize the importance of foodservice facility management but performance is relatively low. Institutional support is, therefore, needed to improve performance. For items with low importance, it seems necessary to improve awareness of the necessity of these items and to provide education in this regard. To gradually improve foodservice management, continuous provision of education and training in these areas are of great importance.

Good snack consumption behaviors are important among elementary students because snack provides additional energy and nutrients and because good dietary behaviors should be formed during early stages of life. This study investigated, among elementary school students, 1) snack consumption behaviors, 2) snack-related nutrition knowledge level, and 3) relationships between snack behaviors and snack-related nutrition knowledge. A convenience sample (N = 372), drawn from 5th and 6th graders of an elementary schools in Siheung-si, Gyeonggi-do, completed a pre-tested questionnaire. More than 85% of the participants snacked more than once per week. Most (77%) had their snacks at home. Fruit and fruit juice were the most frequently consumed and the most liked snack items. Taste was the most important in choosing a snack item closely followed by health/nutrition. Snack-related knowledge level was relatively high and the participants obtained their nutrition knowledge through mass media (30.4%) and family/friends (29.0%). Snack-related nutrition knowledge level and snack consumption behaviors showed positive relationships in various areas such as choosing more nutritious snack items and checking nutrition labels. Although this study was limited by its cross-sectional study design, these positive relationships suggest that better nutrition knowledge could result in better behaviors. Results of this study indicated that factual nutritional knowledge has been well transmitted to students. Therefore, future nutrition education on snacking could focus more on providing problem-solving and operational knowledge.

Korean societies have been experiencing the wholesale structural changes in the rapid currents of recent openness, globalization and democratization, which effect much more heavily in rural areas than in urban areas, so rural recomposition works being an important national concern. In order to systematically reconstruct the rural structure, the decision makers, with a four step hierarchy of rural resident-residents group-community-region, should be endowed with the objective judgement on basic elements of resource potentialities under their control. In this process. rational resource evaluation works would be firstly necessiated from expert groups. Based on the view mentioned above, this study principally aimed at developing a rational evaluation framework for rural resources. For that objective, the first step of the study pigeonholed the total resources items identifiable in rural areas from the existing study results, spatial planning and field surveying data. After then, using the formalized classification criteria of resources items, a tentative goal system for rural resources evaluation was proposed and the final one determined through expert-group checking. The results obtained during the study are summarized as follows ; 1. Using the existing examples of resources identification/classification and the basic data list for county-level development planning as the principal reference ones, total rural resources elements were classified into 3 constituent units : land, natural environment and human resources, which correspond to places to work, to play and to live, respectively, as 3 constituent ones of life-supporting space. 2. Three characteristic areal types were adopted to represent the total rural areas : lowland, upland and seashore areas, and also 3 practical use types to represent the objectives of resources evaluation systems : for land use planning, natural conservation policy and village improvement planning. Thus 9 different types of goal system for resources evaluation were developed(each system by 3 areal typesX3 practical use types) 3. Each goal system has 3-tier classification steps from the higher, middle and lower one. The higher and middle steps should contain equally applicable components to all the rural areas, of which allowable number being around 3 and 4 respectively. However the lower step would contain detailed sub-components changeable to areal characteristics of which allowable number being around 7.

The purpose of this study was to identify the effect of follow-up care for stroke survivors on primary caregivers' quality of life. Quasi-experimental research was conducted in which an experimental group and a control group-each of 15 stroke survivors and their primary caregivers-were consecutively sampled. Data collected from July to September, 1999 by interview using a structured questionnaire with both the experimental and the control groups. After a month, the two groups were given the same questionnaire. The experimental group was also given a telephone follow-up every week for a month, as well as a home visit. The survey instruments used in this study were Saha and Cooper's "Modified Barthel Index" (11 items) for checking the stroke survivors' level of activities of daily living, and a modified form of Jeong's "Quality of life" (18 items) for primary caregivers' QOL level. The obtained data were analyzed by percentage, t-test, $X^2$-test, Kruscal-Wallis test, Spearman correlation coefficient by SAS/PC program. The results were as follows: 1. There was no significant difference in the stroke survivors' ADL level, though the level of the experimental group was higher than that of the control group. 2. There was a statistical difference in the before and after treatment of the primary caregivers' QOL level. In conclusion, the follow-up care program had a useful effect on the quality of life of primary caregivers.
