Objectives: The purpose of this study was to investigate effects of nutrition education providing school lunch by personalized daily needed food exchange units using Food Exchange System for adolescent athletes. Methods: The subjects were 60 sports high school students (educated group, 30 vs. noneducated group 30). Nutrition education was provided for 4 weeks (40 min/lesson/week). In addition, personalized school lunch was served for 4 weeks, nutrition education period. The personalized lunch were provided Food Exchange Units according to personalized daily needed energy. The lessons were '5 Major nutrients, functions and foods', 'My daily needed energy and food exchange units by Food Exchange System', 'My meal plan by food exchange units according to my daily needed energy' and 'Smart choice of healthy snacks and eating outs'. After nutrition education, we examined the differences in anthropometric characteristics, nutrition knowledge, dietary attitude and dietary intake between the educated and the non-educated group. Results: We observed improvements in lean body mass in the educated group. With regard to nutrition knowledge, there were improvements in 'Functions of vitamins', 'Functions of minerals', 'Foods of fat', 'Foods of vitamin', and 'Foods of mineral' in the educated group. In relation to dietary attitude, there were improvements in 'Taking a meal with family and friend', 'Taking a meal at ease', 'Taking a meal with kimchi and vegetables', 'Taking a meal with three kinds of side dishes', 'Priority of choosing snacks' and 'Type of snacks' in the educated group. With regard to dietary intakes according to Dietary Reference Intakes for Koreans, there were improvements in intakes levels of fiber, vitamin A, vitamin C, folate, calcium, iron and zinc. The index of nutrition quality, as indicated by nutrition adequacy ratio also improved in the educated group. Conclusions: These results showed that a nutrition education program providing education lessons and personalized school lunch by food exchange units according to daily needed energy showed positive changes in nutrition knowledge, dietary attitude and dietary intake of adolescent athletes. Nutrition education program providing personalized school lunch by Food Exchange Units may improve dietary behaviors and dietary intakes of adolescents.

This study is concerned with the nutritional status of the packed lunch boxes which are brought by the junior high school students in Capital City of Seoul. Four hundred and eights students of the 8 school districts in Seoul had been randomly selected as subjects. The contained nutrients in the packed lunch were analysed by the Food Composition Table. To observe the influence of home economical status and mother's educational level on the nutrient concents of packed lunches, the chosen subjects were classified into three large groupings, which are upper, middle and low classes respectively. In addition, comparison between the Recommended Daily Allowanced for Korean people-13 to 15 age group-and the contained nutrients in the lunch boxed had been conducted. T-test was applied to clarify the significance of the differences between each group both economical and educational level. 1. The averaged rations between the Recommended Daily Allowances and the contained nutrients in the lunches stand: Calorie 59.7% (566 Cal.) protein 53.1% (18g), animal protein 48.6% (5g), fat 39.8% (5g), calcium 371.% (0.1g), ferret 66.4% (2.9g) Vitamin A 642 1.U. (31.3%), Vitamin $B_1$ 70.2% (0.3mg), Vitamin $B_2$ 41.4% (0.2g), Niacin 77.0%(4mg), Vitamin C 51.9% (13mg). All of the nctrients fall far behind the Recommended Daily, Allowances for 13 to 15 age group. 2. Home economical status brings influence on the kinds of foods which could been. Protein, animal protein, fat, Vitamin $B_2$, Vitamin C showed significance of diffierences between the upper and middle classes. Between the middle and low classes, Protein, animal protein, fat, calcium and Vitamin C showed significance of difference. And finally, between the upper and low classes, protein, fat, calcium, ferret, Vitamin $B_2$ and Vitamin C showed a great significance. 3. Regardless to the living conditions of the subject students, all the nutrients of the lunches packed by the mothers in the entire educational levels did not reach the Recommended Daily Allowances. Protein, animal protein, fat, ferret, Vitamin A, and Niacin showed the significance of the differences between the upper and middle classes. On the other hand, calorie, animal protein, fat, Vitamin A and Vitamin C showed the significance between the middle and low classes. Between the upper and the low classes, protein, animal protein, fat, and ferret showed significance. 4. The mairdish-ice of the lunch boxes supplied calorie, protein, Vitamin $B_1$, Vitamin $B_2$ and Niacin which stand at 83.8%, 56.1%, 52.5%, and 54.8% respectivly when compared with the whole nutritional contents. 5. The side-dishes of the packed lunch lack in variety of cooking methods. One interesting fact is that entire subject students are very favorable to the food cooked with every kind of grains.

Hypertension is a well-known degenerative disease whose prevalence rate increases with age. Management of high blood pressure is a critical concern in preventive strategies to reduce the morbidity and mortality for cardiovascular disease. The purpose of this study was to examine the dietary characteristics of hypertensive program participants, and to establish strategies based on their nutritional needs. Hypertensive patients were enrolled in the program in a public health center or in a local elderly center, at Suwon, in 1999-2000. Trained dietitians interviewed 62 enrollees(24-hour recall) and related variables. Mean body mass index of the subjects was 25.0kg/m². 30.7% of the subjects had a family history of hypertension. The majority of them ate regularly and partook of all available side dishes. They consumed grains and vegetables regularly, but seldom ate dairy products or food prepared with oil. Male enrollees frequently consumed more processed food and animal fat than did female enrollees(p<0.05). An analysis of the percentage of RDA(Recommended Dietary Allowances of Korea 1995) showed that but for ascorbic acid, enrollees consumed nutrients below the RDA. The food group intake pattern was not diverse, thus only 8.1% of enrollees consumed all food groups in a day. An analysis of eating attitude showed that 64.5% of enrollees always added salt to beef soup. Male enrollees showed low food-related self-efficacy compared to female enrollees, especially with reference to reduction of instant food intake(p<0.01), increase in vegetable intake(p<0.01), reduction of monosodium glutamate(MSG) intake(p<0.01). and not overeating(p<0.05). Their perceived barriers for participating in hypertension nutrition programs included lack of time, program necessity non-recognition, and program comprehension difficulty. These results suggest that nutrition education program necessity non-recognition, and program comprehension difficulty. These results suggest that nutrition education programs for community hypertensive patients should focus on increasing participant consumption of foods, expecially dairy products, and desirable eating attitudes. It also suggests that the program should consider should consider encouraging self-efficacy in changing eating behavior.

Oral health is a critical factor for diagnosing overall health, as poor oral health has a negative impact on food intake and results in deterioration of nutritional status. The purpose of this study was to research the needs for food developments for the elderly based on their oral and overall health status. Oral status was significantly associated with self-reported health status, and dry mouth (lack of saliva) especially showed a significant relationship with negative self-perception of both oral and overall health. For both elderly men and women, fish and leafy vegetables were the most preferred side dishes. Bread, rice cake, and beverage-type foods were also preferred for snack development. Disease status of the elderly was significantly related with their preference for food development. For instance, those with diabetes were more likely to ask for anti-diabetic diets. The most important factor for the elderly in choosing food was nutritional balance, and less than 3,000 won was cited as an affordable price. The results could be utilized as basic data to develop foods for the elderly.

This study tried to know the effect of selection attributes for chicken specialty stores on customer satisfaction and loyalty. IPA analysis on relation between the attributes and the satisfaction showed that most quality-related product attributes such as 'the taste and quality of chicken', 'proper portion', and 'fresh ingredients' had high levels of perceived importance and satisfaction. It indicates that the stores need to keep the current good quality. On the other hand, customers showed lower levels of satisfaction in 'reasonable prices', 'quick delivery'(certainty factors), and 'kindness of employees', so that those attributes need improving. The hypothesis testing showed that supplementary product factors such as 'side dishes offered with chicken', 'use of neat and convenient wrapping package', and 'coupon offers' among the customer selection attributes had a significant impact on customer satisfaction and loyalty. Therefore, the owners of chicken specialty stores need to choose a reasonable price to make customers satisfied and shorten delivery time directly related to quality. Also, they need to differentiate their services by continuous employee training and education and provide additional services in order to enhance customer satisfaction for their repurchase.

The Korea School Lunch Program mandates that school meals should safeguard the health and well-being of our children. School meals provide a nutritious diet that contains at least ⅓ of the daily Recommended Dietary Allowances of necessary nutrients at reasonable prices. This study was performed to assess the nutritional management of primary school meals, and to provide basic data for improvement of school meal nutritional guidelines. Three hundred and thirty six dietitians who worked at primary schools were recruited using a stratified sampling method. A survey was done by e-mail with a set of questionnaires about nutritional meal management. During school lunch planning, dietitians referred nutrition standards with priority, followed by students' food preferences and food hygiene. They considered energy as a most important nutrient during primary school lunch planning, followed by protein and calcium. Protein is usually over-served, whereas iron, vitamin A and calcium are usually under-served during primary school meal planning. For first and second grade primary students, grains, meat and vegetable side dishes seemed to be large compared to their eating capacity. Over 92% of school dietitians agreed the needs of food group standards for primary school lunch program. For making a checklist of the school lunch program, energy, protein and calcium were highly recommended, and meat.fish.egg group, vegetable.fruit group and dairy group were also highly recommended by school dietitians. Cooking method was also highly recommended. School dietitians proposed that remodeling of school kitchens and new cooking machine were the most important factors for improving school lunch system. These results suggest that food standards should be established for health-oriented nutritional management of primary school lunch programs. Nutritional checklists could include nutrient-rich foods and food groups, and items about cooking methods.
