The purposes of this study were to (a) measure plate waste of school lunches, (b) evaluate the nutrients actually consumed by students in elementary school foodservice. The survey was conducted between May 11 and July 1, 1998 through the practical measurement and questionnaires. Statistical data analysis was completed using SAS program for descriptive analysis and T-test. The results were summarized as follows: 1. The mean plate waste of menu group were soup, vegetable side dishes, kimchi, and meat side dish in order. 2. There was little difference between estimation and weighing of plate waste. 3. The satisfaction of children with school lunches were significantly higher for boys(73.55%) than for girls(71.13%). The highest level of the satisfaction was meat side dishes among boys and girls. 4. The majority reasons for leaving leftover were 'too big portion' and 'food is not tasty'. 5. There was significant negative correlation between plate waste and student's satisfaction. In summary, increased satisfaction with school lunches in most menus resulted in decreased plate waste rate. 6. Comparison of $\frac{1}{3}$ RDA, energy, vitamin A and calcium were below recommended allowances for boys while energy vitamin A, calcium and iron were for girls. In general, the nutrient intake was more adequate for boys than girls because of the girl's lower allowances.

The purpose of this study was to : (a) examine diabetic patients' sensory evaluation and food preferences, (b) analyze the portion sizes & plate wastes, (c) investigate the factors affecting plate wastes, and (d) determine the nutritional & mometary values of the plate wastes. A questionnaire for determining food preference and sensory evaluation was developed. Thirty-three diabetic patients who were hospitalized in Sanggye Paik hospital in Seoul were studied. Serving sizes and plate wastes were weighed by using an electric scale, and the CAN-Pro program was used to evaluate the nutritional value or the food consumed. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and the Pearson correlation. Using a five-point Likeu-type scale, the temperature s[ore ranged from 3.1 to 3.3 (1 : very poor, 5 : excellent), the preference store was 3.0-3.2 (1 : very dislike, 5:very like), the taste score was 2.9-3.2 (1 : very poor, 5 : excellent), and the amount of food served score was 2.8-3.0 (1 : too little, 5 : too much). Serving sizes were considered insufficient by patients because most of the DM diet was low in calories. Average plate waste for the DM diet was 26.2% of the total served, by weight, and was lower than that for patients consuming a normal diet, which was 30.3%, found in previous research. Those subjects who had been previously hospitalized and who wished to participate in a campaign for food waste reduction produced less plate waste than other groups (p<.05). Plate wastes of the DM diet were negatively correlated with taste, temperature, and preference, and were positively correlated with the amount served: however, these results were not statistically significant. It was found that diabetic patients consumed adequate levels of energy, protein, Ca, Fe, Vitamin B$_1$, Vitamin B$_2$, and niacin, but inadequate levels of Phosphorus, Vitamin A and Vitamin C. The plate wastes were calculated to be 26.2% of the total cost (￦ 3,489), which is ￦9l5. This represents a significant wastage of resources from the hospital. The results of this study could assist foodservice managers in both controlling food wastage, and improving the quality of hospital food services.

The purpose of this study was to examine the dietary attitudes, dish preferences, and plate waste status of elementary school students in Chungnam province. Questionnaires fearuring dietary attitudes, dish preferences, and plate waste measurements over 4 days were administered to 278 elementary school students (3~6th grades; boys 124, girls 154). Regarding plate waste of food, subjects showed the following in decreasing order: soup > vegetable > fish > kimchi > rice > meat. Regarding food preference, cooked rice showed the highest preference among rice dishes, whereas both boys and girls preferred stir-fried rice among one-dish meals. For soup, soup cooked with mear was highly preferred. However, soup with vegetables was preferred less. For meat, soy sauce-glazed chicken and bulgogi were the most preferred boys and girls. In addition, boys indicated a higher preference for most of the meat dishes than girls. Among the many types of kimchi, Chinese cabbage kimchi (Baechu Kimchi) was the most preferred. For the school meals, the served and consumed amounts by boys were higher than those of girls. However, there was no significant difference in plate waste between the boys and girls. To improve management of school meals, dietitians should understand factors that influence students' food preferences.

This research was performed to evaluate the effects of nutrition education on food waste reduction at school food service. A dietitian conducted nutrition education on environmental protection and proper eating attitude and poor eating habits for 3rd and 5th graders at an elementary school in Seoul. The effectiveness of the education was evaluated by surveying the students before and after the education; 375 responses were analyzed. A questionnaire was designed to compare changes of the students' attitudes and plate waste before and after education. Plate wastes of boiled black rice(p<0.05), potato soup(p<0.05), amaranthus herb salad(p<0.01), and cabbage kimchi(p<0.05) decreased significantly after education. Students' eating attitudes improved significantly(t= -6.22, p<0.01) after nutrition education. Major reasons the students did not eat all foods they were served were large portion sizes (30.59%), low menu preference (29.79%), and tastes (17.82%). The menus with high plate waste rates were cooked vegetable items (35.64%) and soup items (26.6%). After education, students' attitudes on ‘food waste pollutes the Earth(p=0.013)’, ‘food preparation for birthday parties(p<0.01)’, and ‘restaurant selection for eating out (p<0.01)’ changed significantly. After education, plate waste and portion sizes that the students perceived were not negatively correlated. In conclusion, nutrition education on proper eating habits and source reduction is an effective method to reduce food waste generation and to improve students' eating attitudes and awareness on environment.

This study was designed to assess the waste management practices, source-reduction programs and related tasks in elementary school foodservice in Seoul. and Kyonggi Province Areas. A questionnaire mailed to 910 school foodservice managers in Seoul and Kyonggi province: a 202% (N=184) response rate was obtained. About 83.7% of school foodservice managers were responsible for managing solid waste. Most foodservice operations take the responsibility of food waste but not packaging wastes. The average disposal cost per month per person was about 19 won and income was about 35 won. Leftovers were mainly disposed with platewaste. Platewaste was reused for the livestook feed(68.0%), and some platewaste was composted(11.6%). Source reduction programs implemented in half of school foodservice operations were adjustment of portion size', checking the plate waste', 'working with classroom teachers on waste reduction campaign', 'providing information leaflet on food waste minimization', posting education materials, 'classroom instruction about food waste minimization', and 'improving cooking method. According to factor analysis based on importance rating. slid waste management activities of elementary school foodservice operations were divided to 7 dimensions such as communication and cooperation with others', 'employee training', 'product quality control, 'yield control', plate waste control', 'purchasing', and 'public relations'. As a result of Important-Performance Analysis(IPA), sine dimensions such as 'communication and cooperation with others' and 'plate waste control were identified in Focus Here' quardrant area which need more enhanced performance.

Hospital malnutrition could be caused by not completing the food served in the hospital. This has been a big problem since it delays the recovery of the patient and extends the length of hospital stay. The purpose of the study was to reduce the plate waste for the DM diet by performing several nutrition service improvement activities. The study was performed in a general hospital with 900 beds. A questionnaire survey was taken by 39 DM patients to obtain their aspect of the hospital foodservice systems and the quality of the meals at the beginning of the study. The amounts of foods served in the hospital kitchen and returned were measured by weights. After the improvement activities, the measurement of the plate waste was performed again for comparison. The average percentage of plate waste for the DM diet was 23.2%. The survey showed no difference by sex, age or duration of admission in plate waste. However, this food wastage percentage showed differences between the patients having a chance to get information about the diet therapy (12.21%) and not having one (26.06%) (p < 0.05). Using a five-point Likert-type scale, the quality of food by its taste was 2.49 (1: very poor, 5: excellent), the temperature score was 3.56 (1: very poor, 5: excellent), and the amount of food served score was 2.95 (1: very poor, 5: excellent), and the preference score was 3.13 (1: very dislike, 5: very like). Nutritional care improving activities were performed by adjusting seasonings, developing new menus, and standardizing cooking methods in order to increase the satisfaction of meal quality. The dietitian's inpatients care protocol was adjusted to expand the nutritional counseling chance for the DM patients. After the improvement activities, the average plate waste was reduced to 14.6%, and the satisfaction of food taste and preference increased to 3.21 (p < 0.001), and 3.36 (p < 0.05) correspondingly. The result shows that, for therapeutic diet patients, food intake could be increased by improving the food service satisfaction by controlling the meal quality and clinical nutritional service activities.
