A survey was conducted to investigate the sanitary condition of school kitchens in one region of Korea. A self-administered questionnaire recommended by the Korea Ministry of Education & Human Resources Development (MOEHRD) was offered to a random sample of dieticians of twenty-five elementary schools for food, sanitation and safety inspection of their kitchens. Air temperature, relative humidity, and airborne microbes in the kitchens were monitored during food preparation, processing and service. The inspection results showed their sanitary condition met the level B of the recommendation of the Korea MOEHRD. The range of air temperature of the kitchens was 21.4∼22.4$^{\circ}C$, and the range of relative humidity was 62.4∼69.6%. The microbiological evaluation of kitchen samples indicated aerobic plate count levels from 22.5 to 26.5 CFU/15 min. These results indicate that the levels of sanitary condition of kitchens in the schools were not satisfactory for safe foodservice although the inspection showed good results. This study suggests that the school kitchens should be monitored and strict inspection is necessary.

This study was conducted for researching demand on dietary education of low-level elementary school students and to develop an activity based textbook and a teaching manual on the subject. For necessity of dietary education, 88.8% of subjects answered dietary education is needed. The desirable frequency of the education was once a week (65.7%). The most appropriate time for the education was "school lunch" (37.5%), "special activity" (29.9%), "regular class" (12.4%) and "after school activity" (12.1%). The most preferred educational method was "experiment and practice" (40.1%). The desirable educational materials were "computer materials" (20.7%), "actual objects" (20.1%), "videotapes" (16.5%), "photographs-pictures" (12.2%) and "fairy tales-cartoons" (12.2%). The students wanted dietary information as "cooking" (26.1%), "growth and nutrition" (23.7%) and "right food information" (20.1%). The textbook was composed of five major chapters, which were "Traditional Dietary Culture", "Food", "Dietary Habit", "Hygiene and Environment" and "Cooking". Each major chapter had five to six smaller chapters, adding up to total of 32 chapters. The textbook had fun characters, illustrations, photographs and cartoons to deliver the main theme of each chapter. The textbook was in activity format so that it coul be readily and directly used in actual classes. The teaching manual was composed of background, goals, teaching plans and teaching points. The smaller chapters had learning goals, teaching-learning resources, important points, teaching-learning processes and reference materials. Videos were produced to help cook five snacks in the cooking chapter. Also, "Healthy Song" was created to be used in classrooms. This textbook will be helpful in children's right dietary habits and growth.

The purposes of this study were to quantify and compare the kind and amount of solid waste generated in two school foodservice operations located in urban and rural areas. A waste stream analysis was conducted to quantify and characterize the kind of waste in the production and service parts of each operation. The SPSS 10.0 for window was used for data analysis. Non-parametric test (Mann-Whitney) was adopted to determine if significant differences exist in amounts of waste generated in the urban school and the rural school. An average of 415 meals, including 43 adult meals, were served daily in the urban school, while an average of 177 meals, including 24 adult meals, were served daily in the rural school. Food waste generated in the production part in the urban school composed approximately 87% and 45%, while that in the rural school composed 71% and 28% by weight and volume, respectively. Waste per meal was not significantly different between the urban school and the rural school in the production part except the cardboard waste. The total waste per meal at lunch was 154g or 465m1 in the urban school and 51g or 334m1 in the rural school. Students in the urban school discarded significantly more food waste and milk than students in the rural school did. The research results suggest that school foodservice dietitians should evaluate the acceptability of menu items based on food waste per meal, and assess the feasibility of implementing a plan for recycling packaging waste and composting organic waste.

초등학교 급식의 메뉴별 나트륨 함량이 중학교 급식의 나트륨 함량보다 높았으나 음식 섭취량이 중학생이 많아서 나트륨 섭취량은 중학생이 초등학생 보다 유의적으로 많이 섭취했다(p<0.05). 비빔밥, 덮밥 등 간장이나 고추장을 기본으로 한 소스류 첨가가 많은 일품식류는 급식 자체의 섭취량 또한 높아서 다른 음식군과 확연히 구분될 만큼 나트륨 섭취에 크게 기여하였다. 반면 나트륨 함량이 높은 구이류 메뉴는 김구이처럼 섭취중량이 매우 작은 경우가 있어서 나트륨섭취에 기여하는 수준은 크게 높지 않았으며 김치류와 무침나물류 또한 해당 음식의 섭취량이 낮아서 나트륨 섭취에 크게 기여하지는 않았다. 초등학생의 끼니당 나트륨 섭취량 평균은 802.2 mg/인으로 WHO 일일섭취권고량(2,000 mg)의 40.1%로 나타났다. 중학생의 경우 1회 점심식사 분량의 나트륨 섭취량 평균은 1,055.9 mg/인으로 WHO 일일섭취권고량(2,000 mg)의 52.8%를 섭취하고 있는 것으로 나타났다. 후식이 높은 칼륨/나트륨 비율을 나타냈는데 과일류가 112.0로 가장 높았으며 음료 및 차류 8.6, 유제품이 3.2로 높은 비율을 나타냈다. 주식류에서는 밥류가 칼륨/나트륨 비율이 22.3으로 칼륨/나트륨 비율이 1이상을 나타내고 그 외의 주식류 및 부식류 전항목은 1이하로 나트륨이 높음을 알 수 있었다. 초등학교 급식(0.66)이 중학교 급식(0.62) 보다 높은 칼륨/나트륨 비율을 보였는데, 이는 초등학교에서 후식으로 과일을 제공한 횟수가 많아 나트륨에 대한 칼륨의 비율을 더 높인 것으로 판단된다. 초등학생, 중학생 모두 한끼 나트륨섭취권장량인 1/3 RDI(WHO, 2000 mg)인 667 mg을 초과하는 비율이 높았다. 따라서 학교급식에서 나트륨 섭취량을 권장섭취량 수준으로 낮추기 위해서 레시피 개선, 학생영양(교)사 교육 및 올바른 식생활에 대한 교육 및 홍보가 병행되어야 할 것으로 생각된다.

The purpose of this study was to investigate meal behavior and food preferences of children with different body types. This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively. Perceived health status was different based on body types, and more of the overweight children answered they are healthy compared to the underweight children, Body types were not significantly different based on parent's education and occupation. Only 56.7% of the children ate breakfast at a regular time, 60% and 42.9% of the children had their lunch and dinner at regular time, respectively. Higher percentage of overweight children had irregular breakfast(20.1%) and skipped their breakfast and dinner compared to the other groups, however only dinner was statistically significant. The most frequently answered reasons for skipping meals were 'no time to eat'(50%) and 'bad side-dishes'(17.0%). Food preference was not different among the body type groups, however rice-cake was preferred in the underweight group, as well as milk and lettuce were preferred in overweight group. The preferences for milk and grain powdered drink(misitgaru) were same as or a carbonated soft drink. Focusing pubericant, it is necessary to have a regular breakfast. With regard to the importance of nutrition and health for children, the nutrition education for meal behavior and food preference to achieve a balanced diet should be considered.

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 sound dietary habit is formed in childhood, which is basic foundation for keeping health. The school foodservice is practiced to provide proper nutritions, to establish the sound dietary habit. Continuous evaluation and improvement are necessary to operate school foodservice effectively. This study was conducted to evaluate the quality of meals served in elementary school based on nutrient content, food diversity. A questionnaire was mailed to dietitian of each school requested for menus of one week. Menus served in 77 schools from each province and major cities in Korea were analyzed. The results of this study were summarized as follows; Compared to 1/3 of RDA for children, many schools provide lower amounts of energy, calcium and Vitamin A. Proportions of energy from carbohydrate, protein and fat were 59.64%, 17.43% and 20.11%, respectively and were not significantly different by the area, the foodservice system, and the number of persons served. NAR(nutrient adequacy ratio) were lowest for calcium(0.67) and Vitamin A(0.65). MAR(mean adequacy ratio) was 0.83. The results of comparison of NAR and MAR by the area, the foodservice system, and the number of persons served were similar to those of nutrient contents. Comparing foods served by the nutrient density were different by nutrient contents, NAR and MAR. Mean nutrient density per meal were higher in large cities than in small cities and rural area, in conventional than in commissary foodservice system. Mean number of dishes and food items per meal were 5.86 and 19.87, respectively. The mean of total quantity of each food group per meal was 352g. The mean of total quantity of each food group per meal were higher in small cities and rural area than in large cities, in commissary than in conventional foodservice system. This study is based only on served menus, and the evaluations of meals based on actual consumption of children are needed. These results suggest that in order to improve the quality of school food service, realistic standard should be suggested and basic study should be done continuously.

본 연구는 공동관리 급식을 시행하는 초등학교의 안전한 급식을 위하여 HACCP 시스템 적용 지침을 개발하고자 경북 경산지역에 위치한 W와 D초등학교의 급식메뉴를 선정하여 2002년 12월∼2003년 2월에 실시하였다. 급식 메뉴에서 학생들의 편식을 교정하데 도움이 되며, 미생물에 의한 오염 가능성이 높은 냉동 해산물을 사용하는 오징어덮밥을 HACCP 적용메뉴로 결정하였다. 오징어 덮밥의 생산 단계에 따라 공정흐름도를 작성하여 생산단계에서 반드시 점검해야 할 HACCP을 적용 지침를 제시하였다 (1) 해동 및 세정: 냉동 오징어는 흐르는 수도물로 해동하여 손질한 후 조리직전까지 식품의 내부온도는 가능한 1$0^{\circ}C$ 이하로 유지 또는 냉장보관하고, 소요시 간은 30분을 초과하지 않도록 한다. 채소는 3구 세정대에서 세정하고, 지하수 사용은 배제해야 하며 작업은 20분 이내에 완료되도록 한다. (2) 썰기: 오징어와 채소를 사용하는 칼과 도마는 구별하여 사용하며, 조리원의 개인위생을 점검하고, 칼과 도마를 포함한 조리기구의 사용 전 후의 세정 및 소독상태를 확인한다. (3)조리: 오징어와 채소는 각각 조리(데치기와 볶기)한 후 함께 섞어 끓인다. 오징어는 완전히 익혀야 하며, 완성된 음식의 내부온도는 94$^{\circ}C$ 이상이어야 하며, 21분 이상 가열한다. 맛보기 는 올바른 방법으로 실시해야 한다. (4) 배식: 조리원의 위생습관(마스크, 머리수건 및 일회용 장갑착용)을 확인하고, 음식 (오징어덮밥)의 내부온도(84.4$^{\circ}C$이상)와 조리실의 이상적 실내온도(15∼18$^{\circ}C$), 조리기구 취급이 위생적으로 이루어지는지 확인한다. 공동관리교의 안전한 급식은 표준화된 메뉴에 따라 공정 흐름도를 작성해야 하며, HACCP이 적용된 지침서가 모든 메뉴에 따라 갖추어 져야 비로소 실행될 수 있다. 따라서 정확한 온도를 측정하고 HACCP을 이해할 수 있는 교육프로그램과 다양한 종류의 식단을 생산할 수 있는 기본적인 시설과 기구를 갖춘 조리실, 전문 영양사와 고용 조리원 확보 및 안전한 식수공급이 이루어 져야 하며 이를 뒷받침하는 국가차원의 지원과 지속적인 연구가 필요하다고 사료된다.

Objectives: The purpose of this study was to compare the physical activity level (PAL), the physical activity pattern and the energy expenditure in male and female elementary school soccer players using the accelerometer and the physical activity diary. Methods: Twenty-five (male 11, female 14) elementary school soccer players (9-12 years) participated in this study. During their daily activities, they wore an accelerometer for seven days (five weekdays and two weekend days) and completed the physical activity diary for three days (two weekdays and one weekend day). PAL was calculated by using the physical activity diary and three equations (Pate Preschool, Freedson Children, and Freedson) were used to calculate the intensity of physical activity and energy expenditure from the counts of accelerometer. Results: The average of physical activity by day of the week, CPM (Counts Per Minute) and METs (Metabolic Equivalents) were significantly higher in males ($723.3{\pm}149.2CPM$, $2.07{\pm}0.18METs$) compared to females ($505.6{\pm}119.9CPM$, $1.79{\pm}0.20METs$), but there was no significant difference in PAEE (Physical Activity Energy Expenditure) between the two groups (males: $15.5{\pm}9.1kcal/day$, females: $11.5{\pm}6.0kcal/day$). During weekdays, physical activity intensity was significantly higher in males compared to females at lunch time and training time than at other times. In both genders, the PAL was higher during weekdays (males 1.98, females 1.89) compared to weekend (males 1.62, females 1.61) (p<0.05). Conclusions: Our study observations suggest the necessity to develop an accelerometer equation for accurately evaluating the physical activity of elementary school athletes.
