Foods with high waste rates were vegetables, fishes and shellfishes. Survey results were compared with other food composition tables. Foods with 30% higher waste rate than other food composition tables were squash leaf, pacific ocean perch, sweet potato stalk, water cress, green peas, alaska pollack, bluefin tuna, beka squid, crown daisy, dodok, amaranth, beef ribs. Food which waste rates turned out to be decreased by about 30% in this study were corb shell, pomfret, sea mussel, warty sea squirt. For the menu planning, reasonaly exact waste rates for each food items are essential.

Thirty six hospitals having more than 100beds in Seoul, Inchon and Kyungkido were the subjects of this study. Data was collected through surveys. The survey was conducted during March and April in 2002. The Questionnaires were mailed to the 36 directors of dietetic departments of the hospitals and 36 managers of contracting patient food services. Statistical analysis was completed using SPSS Win(11.0) for descriptive analysis and t-test. The results of the study are summerized as follows; Ⅰ. Hospital perspective : The range covered by contract food service was 63.3% and 36.7% in hospital food services, and medical nutrition services. The patient and employee food services were in 83.3%, and patient food services were in 6.7%. The methods selecting contractors are general, limited, selected and competitive biddings, and private contracts. The responsibility for supervision of contract food services was the dietetic department (51.7%) in most cases. Hospitals having personnel responsible for contracting affairs were in 75.9% of the cases and 24.1% did not have personnel. The biggest reason for contracting was facilitation of personnel management. The most important criteria on selecting food services contractors was the professionality of the contractor. Ⅱ. Contractor's perspective : The cost per meal in the year 2001 was composed of 1,905 won for food cost, 1,081 won for labor cost, 222 won for expenses, 114 won for VAT, 14 won for rent and 146 won for miscellaneous or controllable expense, representing 109 won loss per meal. The profit-and-loss contract cost is higher than the fee-contract cost. The ratios of food cost, labor cost and expenses are higher and the ratios of miscellaneous or controllable expense, VAT, rent and profit are lower in hospitals with more than 400 beds compared with those less than 400 beds. However, no significant differences are present between these two groups of hospitals. The actual contract period was 2.2 years upon initial contract and 1.2 years upon renewal.

The purposes of this study were to find factor which influence on the selection criteria of food supplier. Questionnaire were distributed to 52 general hospitals with more than 400 beds located in Seoul and Kyongin province, and responded questionnaires were collected from 44 dietetic departments (84.6%) and 18 purchasing departments (34.6%). The main results of this study can be summarized as follows: (1) supplier selection criteria include quality, service, cost and supplier competency. (2) With having been met with tight competition and market opening, hospitals plan a strategy to improve quality, service and they tend to have more interest in various supplier selection criteria. (3) Purchasing departments estimate more highly the rate of reflection in considering supplier selection criteria than the rate of importance about cost criteria, which reveals that purchasing departments sensitively respond to cost cutdown. (4) When selecting suppliers, a significant(p<.01) influence of stability of supplier industry environment on the selecting criteria such as the importances of quality, service, and supplier quality are recognized only after recognizing the stability of food delivery industry. Food supplier industry secures stability more quickly through major companies' participation in food distribution industry and this will reveal the importance of supplier selection criteria. (5) Suppliers which are selected by the quality criteria, service criteria, supplier quality criteria make efforts to communicate with foodservice departments, to give more proper information about substitute food, new product, and to make commitments, while suppliers which are decided by cost criteria do not establish supportive relationships with foodservice departments.

Control group was not given any special education, while experimental groups were given nutritional education for 4 weeks. The effects of education was evaluated in the aspects of preference changes for vegetables, nutritional knowledge, attitude and food behavior of the subjects The results are summarized as follows. 1. Preferences to cucumber, lettuce, chinese cabbage and raddish were high in three groups while greenonion, onion, lotus roots and red pepper didn't suit for their taste. 2. Significantly increased scores for the preference to red pepper, pumpkin, Dorajee(root of chinese bell-flower), braken, mushroom was shown only in the children who had nutritional education while the children in the group of Mothers Education improved their preference only cabbage and lotus roots. 3. Nutritional knowledge of the children in Children Education group has improved significantly(p<0.05). While there was no significant difference between control and Mothers Education group. 4. When scores for food habit of mother and children were estimated, there was no significant difference among three groups. However, score of food habit in children was higher than that of mothers. 5. Food habit and nutrition knowledge of mother were not well corelated with dietary attitude and behavior of their children. These results indicate that the program of nutrition education in the present study can improve the food choice of children for vegetable and correct one-sided food habit. The program applied in this study would serve a kind of model for the dietetic teachers to guide the children who mainly dislikes vegetables.

In Korea, implementation of nutrition support guidelines has been limited due to strict health insurance reimbursement policies as well as the lack of consensus on the best approach to TPN management. We examined the impact of TPN provision to hospitalized patients where NST (nutrition support team ) consultations were not requested by their primary physicians. The study showed the followings : 1. The median dutation of TPN provision was 8 days, but many patients were on TPN for less than 1 week. 2. The intake of energy and protein were less than the patient's requirements 3. Lipid emulsion was not provided to the most TPN patients. In conclusion, the role of NST should be expanded and studies are needed not only on TPN formulations which are suitable to Koreans but also on the cost-effectiveness of NST activities. TPN policies and protocols should be established based on the needs of each hospital.
