This study was designed to analyze and compare production management practices and labor productivity between conventional and commissary school foodservices and 46 dietitians of commissary school foodservices in Kyunggi-do. The response rates were 89.7% and 91.3$\%$, respectively. The number of meals served was ranged from less than 100 to over 1, 900 in conventional school foodservices and from 200 to 1, 600 in commissary foodservices. Thirty three conventional foodservices(42.3%) produced less than 300 meals per day. Numbers of satellite school per central kitchen were ranged from 1 to 5 schools ; fifty percent of commissary foodservices have contained 3 satellite schools. Meals for satellite schools were transported between 11:00 a.m.and 12:00 a.m ; transportation time was from 10 to 90 minutes. Waiting time before service in satellite schools was between 10 minutes and 80 minutes. Part time employees supported by parents were hired in 37.3$\%$ of conventional and 50$\%$ of commissary school foodservices. Voluntary workers were supplied for 64.9$\%$ of conventional and 52.4$\%$ of commissary school foodservices. Labor productivity was calculated from work schedule. Labor productivity(labor minutes per meal)was lowest in foodservices with 101-4-- meals(8.48 min)was lower than that of foodservices with above 401 meals ; no significant differences were found among 401-700(6.02 min), 701-1, 100(4.01 min), 1, 101-1, 500(3.41 min), and 1, 501-1, 900(3.15 min)meals in conventional foodservices. Labor minutes per meal of foodservices which served less than 400 meals(6.90 min) per day was significantly lower than those of foodservices which served 401-1, 900 meal(3.41-4.92 min) in commissary foodservices(p<0.05)

The purpose of this study was to analyze the status of school foodservice facilities, utilities and equipment & sanitary education in provinces, This study was carried out from September 2008 until December 2008 and is targeted towards schools' dietitians that work at schools with school foodservice. 1,623 schools participated in this research and Kangwondo, Choongchungdo including the metropolitan area with frequent occurrence of food bone disease were the targets of this research. The regional distribution of this research is as follows; 377 schools in Seoul, 648 schools in Gyeonggido, 160 schools in Kangwondo, 438 schools in Choongchungdo equaling 1,623 schools in total. And out of the total 1,623 schools, 815 (50.2%) were elementary schools and 808 (48.8%) were middle and high schools (p < 0.001). Most of the elementary schools, excluding 4 schools, were self-operated. In the case with middle and high schools, 81.5% (513 schools) were self-operated and 18.4% (295 schools) were contracted. When dealing with the sanitation management of school foodservice in Kangwondo and Seoul, elementary schools were less equipped with equipment and facilities than middle and high schools which proved that they were in need of improvements (p < 0.01). Schools with self-operated foodservice, in particular, were in need of preparation zone improvements. 52.3%~88.0% of stainless equipment such as utensils, spoons/chopsticks, subsidiary food tray, and food trays were sterilized by dryers. Work tables, vegetable slicers, and mincers were chemically sterilized and plastic materials were sterilized by ultraviolet rays. Data from newspapers, Internet and TV are collected beforehand and then an annual hygiene educations plan for employees are put together. Hygiene education for employees are carried out monthly through oral method.

A nutrition education program for teachers and caregivers of the preschool children can be most effective when it is based on a comprehensive needs assessment dealing with sociodemographic factors, dietary habits, and nutrition. The purpose of the present study was to investigate current dietary habits and nutrition knowledge of the teachers and caregivers of the day-care centers. Two hundred forty two teachers and caregivers were administered a questionnaire which was designed to ascertain informations on sociodemographic data, dietary habits and nutrition knowledge. Dietary habits of the teachers were found to be significantly different by sociodemographic variables; breakfast skipping/meal irregularities (age, p=0.011); frequency of snacking (education level p=0.031); preference for salty taste(age, p = 0.000, marital status p=0.038); preference for sweet tarte (age p=0.009); preference for vegetables (income level p=0.050); frequency of eating out (age p=0.028, marital status p=0.001); frequency of coffee drinking (age p=0.019). Daycare center teachers' nutrition knowledge level was found to be less than adequate expecially on nutrients that are liable to be deficient in young growing children and their food sources. Proportions of the teachers who answered correctly to the questions on foods rich in vitamin A, iron content of milk, bioavailability of calcium in plant foods were as low as 20.2%-54.5%. The most frequently used sources of nutrition information were mass media such as TV, radio, newspaper and magazines. Only 2.9% of the subjects reported that they obtain nutrition information from health professionals such as nutritionists/dietitians, physicians, and nurses. These findings are applicable at the planning and implementation stages of various nutrition programs for the improvement of dietary habits and nutrition knowledge of the teachers and caregivers of the daycare centers. Further studies are needed to investigate the effects of teachers' dietary of habits and nutrition knowledge on food habits of young growing children.

This study was conducted to evaluate the performance of sanitation management within school foodservice facilities and utilities in Gyeongbuk province. Data collection was carried out through surveys given to 200 school dietitians from the province. A total of 108 were usable, resulting in a 54.0% response rate. Statistical analyses were done using the SAS package program (version 8.2 for Windows). Of the study population, 58.3% had more than 10 years of work experience, and 64.8% worked in elementary schools. With regard to the style of foodservice system, 47.2% were urban and 46.3% were rural. Also, 89.8% of the school foodservices provided meals once a day. The performance of the sanitation management items of the facilities and utilities used to provide school foodservice was evaluated using a 5-point Likert scale. The average score for the 25 items was 3.35 points. 'HVAC system installed in foodservice establishment' had the lowest average score at 2.20 points. Whereas 'provide adequate storage capacity to allow refrigerating and freezing and an adequate thermometer is installed and temperatures monitored' had the highest average score at 4.19 points. Nine out of the 25 items were lower than the average score. The performance scores of high schools were significantly higher than those of elementary schools or middle schools for 'window materials are provided that are not liable to break' (p<0.001). The performance scores for urban style foodservices were significantly lower than for rural foodservices for 'floor of kitchen is constructed to maintain a dry system' (p<0.05). In response to questions on kitchen utensils and equipment, significant differences were shown according to the number of meals served per day in 21 out of 56 items, and the style of foodservice system showed significant differences in 14 of the 56 items. Foremost, to make better use of the foodservice facilities and utilities in Gyeongbuk province, immediate improvements should be made for management items in which the degree of performance was below the average score.

Sensory factors are important determinants of appetite and food choices but little is known about factors affecting taste acuity and preference of Koreans. Any factors causing deficits in sweet taste perception may lead to over consumption of simple sugar, which is related to several chronic diseases. This study was conducted to determine factors affecting sweet taste sensitivity and preference. Subjects were 30 government employees who were serving as school dietitians or in the area of public health while they were studying in the program for the qualification to become nutrition teachers. Sweet taste threshold and the optimally-preferred sweetness of omija jelly were determined by a sensory evaluation and general characteristics, health-related lifestyles, dietary habits and food preferences were determined using a self-administered questionnaire. For the subjects of this study, detection threshold concentration of sucrose solution was $0.184{\pm}0.06%$ and optimally-preferred sucrose concentration of omija jelly was $13.88{\pm}2.28%$ and there was no significant correlation between the sweet taste sensitivity and preference. Subjects who had higher(${\ge}4$ out of 10) physical or psychological stress and who had late getting-up time (after 7am) tended to have lower sweet taste threshold (higher sensitivity) than their counterpart. The sweet taste preference determined by optimally-preferred sucrose concentration of omija jelly tended to be lower in the subjects who eat slowly. Those who answered in the questionnaire to prefer sweet foods did have significantly higher optimally-preferred sucrose concentration of omija jelly. Further research is required to determine whether decreased sensitivity and increased preference for sweetness can increase the actual intake of simple sugar.

An analysis for a period of 15 months (from September 2000 to November 2001), of the nutrition counseling internet site, “Dietnet” served by the Korean Society of Community Nutrition, showed the following results. Nutrition counseling was conducted without charge by 50 professionals, including professors in the food and nutritional areas, medical doctors, and dietitians. Counselees consisted of mostly females under 30 years of age. Although two thirds of the users of this site asked questions anonymously, they were very sincere. They asked questions mostly related to their own concerns, but there were quite a few inquiries about their parents or grandparents. There were significant differences in the counseling contents depending on the ages of the counselees. Teenagers showed the highest interest in height growth and weight control, whereas people in their twenties were mostly interested in diseases, foods, and weight control. Those over the thirty made inquiries mostly about diseases. The most frequent questions were relevant to gastrointestinal, circulatory and hepatic diseases. As indicated above, counseling questions included of a variety of both comprehensive and specific questions. There were also quite a few questions related to decisions on the correct usage of specific foods. Therefore, we recommend that more professionals, such as food science majors, medical doctors who practice western and oriental medicine, and other professionals who specialize in psychological behaviors related to weight control and infant food habits be recruited to serve the site more effectively and intensively. In light of the further need for internet sites with nutrition counseling and delivery of nutritional information to the public, nutritionists capable of managing websites are also required.

The purpose of this study was to determine the prevalence of obesity and to examine the eating habits of elementary school students in Kwangju. The study was carried out on 931 students(male : 454, female : 477) in September and October of 1996. The results are summarized as follows ; Obesity was defined as body mass index(BMI) that exceeds 20. The rate of obesity was 10.0%(male 4.7$\%$, female 5.3$\%$) in subjects. Subjects were divided into 3 groups : normal group(BMI〈20), mildly obese group(20〈BMI〈25), and moderatly obese group(25〈BMI〈30), respectively. With regard to frequency of skipping breakfast, 9.1$\%$ of normal children and 17.5$\%$ of mildly obese children and 33.3$\%$ of moderately obese children had skipping every morning(p$\ll$0.001). With regard to the regularity of meal time, 62.1$\%$ of normal children had ‘regular meals’but 58.0$\%$ of mild obese children and 50.0$\%$ of moderate obese children had‘irregular meals’(p$\ll$0.05). With regard to meal volume, obese children consumed much more meal volume than normal children(breakfast p$\ll$0.001, lunch p〈0.005, dinner p$\ll$0.001). With regard to try to lose weight, 22.9$\%$ of normal children and 55.6$\%$ of mild obese children and 83.3$\%$ of moderated obese children indicated they had attempted(p$\ll$0.001). The results of this study showed that the prevalence of obesity in elementary school students in Kwangju has a tendency to be increased. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children. (Korean J Community Nutrition 2(4) : 486-495, 1997)

Objectives: The aim of this study was to investigate sodium reduction practices in school foodservice in Daegu. Methods: The survey included 199 nutrition teachers and dietitians working at elementary, middle and high schools in Daegu. The survey topics included the following: the frequency of salinity measurement, workers in charge of the measurement, average salinity of the soup and stew served, frequency and difficulties of offering low-sodium meals, Importance-Performance Analysis (IPA) of sodium reduction methods in school foodservice and the need for political support in encouraging sodium reduction. Results: The mean salinity of the soup and stew was higher in high school foodservice than in elementary and middle school foodservice. Middle and high schools have difficulties in offering low-sodium meals due to concerns of decreasing satisfaction for the meals. The results of the IPA of programs to reduce sodium in school meals showed that most of the items in the cooking and serving stages were in the 2nd quadrant (Keep up the good work), and all purchasing and menu planning stages occupied the 3rd quadrant (Low priority). To reduce sodium in school meals, government support is required in developing low-sodium recipes for school foodservice, encouraging education on sodium reduction for school foodservice officials and developing low-sodium food for institutional foodservice. Conclusions: To encourage sodium reduction in school meals, the priority is to make low-sodium recipes available. Also, it is necessary to develop a program that calculates the sodium content in menus and processed foods through National Education Information System and to establish standards for sodium levels in school foodservice.

The purpose of this study was to examine nutrition management conditions of lunch with the elementary schools and middle schools in the Changwon area. 292 students (5th and 6th graders) from three elementary schools and 330 students from three middle schools (boys, girls, and co-ed) participated in the aggregate selective plate waste measurement for 5 days. Planned menus, serving sizes and plate waste amount data were collected. Nutrient analyses for the planned, served and consumed menus at school lunches were performed by using CAN-PRO 3.0. Nutrient analyses of the planned, served and consumed menus were compared with nutrient management standard (former edition) for school lunch and 1/3 Korean Dietary Reference Intakes (KDRIs). Significant difference was found in the average consumption rate between the elementary schools (82.2%) and the middle schools (71.8%). Specifically, the consumption rates of steamed rice (p < 0.001), side dish 1 (p < 0.001), and Kimchi (p < 0.01) at the middle schools were significantly lower than those of the elementary schools. When the nutrient contents in the served menus were put into percentages to the nutrient contents in the planned menus, middle schools (92.3%) showed bigger serving loss than the elementary schools (95.4%). In the nutrient assessment comparied with nutrient management standard (former edition), middle school lunches showed comparatively less energy or less some nutrient contents against the standard than the elementary school lunches. Specifically, in case of boys in middle schools, Vitamin C was the only nutrient content that satisfied the standard in the planned menus, served menus and consumed menus. In the 1/3 KDRIs based assessment, middle schoolers were found not to be provided proper nutrients with school lunches. To improve nutrition management at middle school foodservices, dietitians should reinforce nutrient assessment for menu planning, and try to decrease serving loss and plate waste.

This study was conducted to develop and evaluate food safety training program for employees in foodservice operations. The developed CD-ROM was consisted of 5 parts: foodbome illness, personal hygiene, food handling in food production steps, HACCP system, and sanitary facilities. It has made slides for all contents, the animation and movie to raise interests and concentrations, and illustrations and pictures to understand. The evaluation checklists were developed 15 questionnaires including understanding(5), information(3), concentration(4), recommendation(2), and the most important factor(1) and measured by Likert 5-point scale. Fifty-four dietitians in Daegu and Gyeongbuk schools, hospitals, and industries foodservice operations responded to the surveys. The results are as follows; The most important part in the CD-ROM was personal hygiene(33.3%). The total mean was $3.95{\pm}0.41,\;3.91{\pm}0.46$ on understanding, $3.89{\pm}0.50$ on information, $3.87{\pm}0.55$ on concentration and $4.29{\pm}0.49$ on recommendation. The score was significantly higher in the recommendation part than others. Overall, as the developed CD-ROM has achieved fine score, a study on the effect of education needs to be followed. Moreover, consistent and organized education by developing a variety of sanitation education methods should be conducted.
