The study was carried out to investigate the efficacy of current nutrition labeling of processed foods and examine awareness among university students of nutrition information given current nutrition labels, and also awareness of the one-serving size of snacks that come in differently sized packages. A total of 100 students in Chungbuk, Korea participated in this study. About 60% of the subjects knew about nutrition labeling; however, a very small percentage (11%) of the subjects reported an experience of being educated about nutrition labeling. Also, just 32% of the students checked nutrition labels when they purchased processed foods. When understanding of nutrition information on labels of snacks in differently sized packaging was tested, over 80% of the subjects understood nutrition information accurately. Five different package sizes were studied. Of these 5, packages containing about 200% of one standard serving showed the highest rate of misunderstanding of total energy contents per container. Interestingly, the students most strongly preferred containers that contained 300% of one standard serving. From these results, we conclude that students consider the current recommendation for a serving size to be small, which may be related to misreading of nutrition labels of snacks that come in packages containing less than 300% of one standard serving size. To improve accurate understanding of nutrition labels of snacks, total package labels or dual column labels on packages containing less than 300% of one standard serving size should be considered.

The purpose of this study was to estimate the effect of serving sizes on dish wastes, nutrient intake, and diet satisfaction for reduction of dish waste products. The dish waste, energy and protein intake, and satisfaction scores before and after dining were compared in 44 subjects fed various serving sizes(100%, 90%, 80% of standard size) of 10 frequently consumed Korean dishes. The result are as follows: 1. Average age, height, and weight of 44 subjects were 30.5, 174.0cm, and 68.1kg in men and 26.2, 164.2cm, and 53.5kg in women, respectively. 2. There was a significant difference in the dish waste rate of 10 Korean dishes to serving sizes. The range of dish waste rates of 10 Korean dishes was 13.14-33.04%. 3. The average energy intake from 10 Korean dishes in which 100% of the standard serving size was served was lower than Korean RDA. Protein intakes from Sulungtang, Yukgaejang, Deunjang-ggigae, and Bibimpab with 100% servins size, Soondubi-ggigae 90% servins size, and Galbitang, Bulgogi-bakpan, Sangsungui-bakpan, Bakpan 80% of standard serving size were higher than Korean RDA. 4. The satisfaction score before dining on Sulungtang, Bulgogi-bakpan, Sangsungui-bakpan decreased with decreasing serving size. However, there was no significant difference in satisfaction score after dining to serving size. These findings indicate that dish waste rate and diet satisfaction of 10 these Korean dishes are fixed and energy intake is insufficient. Therefore, for reduction of food waste and reasonable serving size of dishes evaluated in this study, there should be more studies about Korean menu development with decreasing serving size and increasing energy density.

Dietitians in various fields have used food exchange lists for food preparations. However it seems that the present food exchange lists are complicated, thus they cause many problems for dietitians to use in the fields. Therefore this study evaluated to the extent of awareness and utilizations of KDA food exchange lists in dietitians and also collected dietitian's opinions for revising food exchange lists such as serving size, serving calories, and for unifying food guidelines and dietary and dietary guidelines for Korean to one simple guideline. 192 dietitians who presently work in urban and rural areas were recruited and data based on survey were collected. As results, most of dietitians(87.5%) knew well about food exchange lists, but only 7.8% of them always would use food exchange lists for menu planning, 56.3% of dietitians did not use it at all and 34.4% occasionally use it. And 88.0% of dietitians wanted to revise food exchange lists totally or partially, 69.8% of dietitians hoped to amend various calories per one serving in food exchange lists to one serving calorie. The desirable on serving calorie was selected as 100kcal(51%) or 50kcal(38%) by dietitians. The dietitians in this study understood very well dietary guidelines(86.5%) and food guidelines(88.5%) for Korean, and 66.1% dietitians wanted to unify both guidelines. In case of unification of guidelines, dietitians answered that 7-8 items(30%) or 5-6 items(27%) should be included in guideline. In the question about reference value for daily allowance, most dietitians(56%) satisfied with the present various reference values for various generation while 28% of dietitians wanted to change to have one reference value (standard with 2000kcal, adult female). This study will provide basic informations for revising or adjustment of food exchange list and dietary or food guidelines for Korean.

The use of food frequency questionnaire to estimate dietary intake has become widespread in epidemiologic studies. It has been suggested that knowledge about a person's usual serving size of each food, in addition to consumption frequency, will improve the accuracy of this method. This study was performed to investigate the nutritional status and one sowing sizes of commonly consumed dishes in Korean college women. Intakes of dish or food in 156 college women were measured by 7-day weighed food records in May, 1992 and May, 1993. For each dish or food, variance in one serving size was partitioned into within-person(intraindividual) and between-person(interindividual) components. All nutrient intakes except vitamin A and vitamin C were less adequate. The major dish groups which contributed to the most daily nutrient intakes were boiled rice, bread, fruits, dairy product, and biscuit and snack groups. In more than 50% of dishes, the within-person variation was greater than between-person variation. And the variety and amount of food which was used in one dish were too variable to make standard recipe.

Today, the role of kindergarten is more important as nutrition provider through snack and meal services. Desirable kinds and amounts of food items at school lunch menu were important factors of nutrients intakes in children. This study was performed to assess the kindergarten's meal service program (snack and lunch) and the consumption amount of lunch according to each dishes. Twenty four institutions that cared over one hundred children were observed at Seoul and Kyunggido area. Well-trained observers checked meal and snack serving activity and foodservice facilities by formal checklist. And using the weighing method assessed the consumption levels of food items at lunch. During 3 days, 30 children in each kindergarten were selected randomly according to age, observers measured serving and residual weight of each food. The data was compiles by performing ANOVA-test using SPSS WIN 10.0. The result were as follows: 1) Foodservice facilities in kindergarten was limited to provide qualified foodservice. $91.7\%$ of institution had kitchen, $41.7\%$ had dinning. The kitchen equipment possession rate was $12.5\%$ (oven), $30.8\%$ (heating cabinet), $58.3\%$ (refrigerator). The rate of using document about foodservice was used $83.3\%$ (menu list), $41.7\%$ (daily foodservice record), $25\%$ (standard recipe). $41.7\%$ of institution employed licensed dietitian. Only $41.7\%$ of subjects preserved meal after daily meal service. 2) Meal serving size was decided by teacher, $54.5\%$ at snack and $43\%$ at lunch and pre-divided individual portion type was $36.4\%$ at snack and $28.6\%$ at lunch. The rate of cleaning activity before meal was $72.2\%$ at snack, $90.5\%$ at lunch. And nutrition or sanitation education activity was more performed at lunch time, for examples brushing teeth activity was $12.5\%$ at snack $85.7\%$ at lunch. 3) The consumption amounts of plain cooked rice was $112.7{\pm}26.1{\cal}g$, cooked rice and cereal was $93.06{\pm}27.97{\cal}g$, curry rice was $208.35{\pm}64.84{\cal}g$ and the consumption amounts of these main dishes was significantly different by age (p < 0.001). The consumption amounts of soup was very different according to children's preference. The consumption amounts of seaweed soup was $120.18{\pm}82.13{\cal}g$, wild sesame and bean-paste soup was $40.64{\pm}23.16{\cal}g$. The consumption range of kimchis was from $6{\cal}g\;to\;13{\cal}g$, jorim (braised food) was from $3{\cal}g\;to\;25{\cal}g$, fried food (include stir fried, deep fat fried, pan fried) was from $14.5{\cal}g\;to\;22{\cal}g$, vegetable dish was from $3{\cal}g\;to\;16{\cal}g$. These consumption amount of each dishes was not reached recommended portion size of nutritionally planning menu by nutritionist.

The purpose of this study is to investigate and analyze the present state of elementary school libraries in Daejeon Metropolitan City. For this 50 schools are surveyed by questionnaires on two groups of teachers, those that take charge of school library and those who do not. As a results of this research following issues are emerged. First, the present state of surveyed school libraries is below standard with regard to the amount of books and size and it is required to improve these poor conditions. Second, the space programs are not sufficient to conduct enlarging scope of school libraries, which is conspicuous in spaces for affording librarians, supporting various activities and serving user's convenience. Third, in spite of poor conditions in school library facilities, respondents' satisfaction rate is not so low and there's no obvious demand for diversity of spaces.

This study was to investigate current regulatory status of nutrition labeling in advanced countries, such as US and Japan. In US, the mandatory and voluntary components and the order in which they must appear are total calories, total fat, cholesterol, sodium, potassium, total carbohydrate, protein vitamin and iron. The amount of each nutrient must be reported on the basis of the serving size except vitamines and minerals. In Japan, new regulatation on nutrition labeling was made in 1995. For nutrition labeling on processed food, a standard must be appeared and it is mandatory. The union of Europe and Codex also newly regulated on nutrition labeling. It is time to make new regulation on nutrition labeling for being advanced country.

BACKGROUND/OBJECTIVES: Use of smaller plates to control food intake is a commonly recommended strategy for restricting energy intake, despite conflicting results. Therefore, the aim of this study was to examine whether or not three different sizes of plates influence energy intake during a multi-itemed buffet meal in normal weight women. SUBJECTS/METHODS: This was a cross-over study conducted on 37 female participants aged 19-25 years with normal BMI levels. Participants were recruited from Hacettepe University and the surrounding community. On experimental days, participants ate a standard breakfast and were then randomly assigned to eat lunch using a small (19 cm), medium (23 cm), or large (28 cm) diameter plate. Visual analogue scale (VAS) scores on sensory and satiety outcomes were measured for all meals. Energy and macronutrient intakes during lunch were recorded. RESULTS: There was no evidence that use of a smaller plate size reduced energy or specific macronutrient intake during the free choice lunch meal. Multiple visits to the serving table were not associated with energy or macronutrient intake. Plate size did not affect VAS scores during the test days. CONCLUSIONS: Plate size did not influence energy intake, meal composition, or palatability in normal weight women during a multi-itemed open buffet lunch. Studies in natural settings at the population level are needed to clarify current outcomes.

The purpose of this survey was to investigate the operation and the environment of foodservice in elementary schools nationwide. A questionnaire about foodservice management to practice and foodservice operation was mailed to dietitians of each school . Of the 1, 416 schools that participated in this survey, 388 schools were selected for analysis. The main results of this study are as follows. More schools in small cities . Education levels of dietitians were significantly different from area to area. Mean total length of employment for dietitians at school foodservice was 4.7 years and varied significantly by area and the type of foodservice system. Foodservice has been operated for 2-5 years in most of schools. Schools in large cities served more people than those in small cities and rural areas. Also , schools adapting conventional foodservice system served more people than those adapting commissary or joint management system. Foodservice expense also veried significantly by area and foodservice systems. Mean foodservice expense per meal were significantly higher in schools adapting commissary system than those adapting other systems. Most schools employed dietitians, cooks, and assistant cooks, but not engineers not drivers. Mothers of students were working voluntarily. The degree of participation by mothers in cooking , serving , and cleaning was higher in schools of small cities and rural areas than those in large cities, in schools adapting commissary or joint management system than those adapting conventional system. Education and training ranked as personnel management had one of the hardest tasks. Education and training of employees were also difficult for dietitians, especially in commissary or joint management systems. Percentage of schools having separate lunchroom was higher in small cities rural areas than in large cities, in joint management or commissary system than conventional system. Most difficult matters in serving was the portion control. Over 40% of schools did not use standard recipes. Menu cycles were shorter in schools in small cities and rural areas which adapted the joint management system than area other schools. Except refrigerators, thermos , display racks, sterilizers, sinks, worktables, and table, all other equipment were insufficient in most of schools. More than half of the schools didn't have rice cookers, flatware racks, and distributing carts which are stated plainly in detailed enforcement regulations for school foodservice. Cooking equipments were described as the most needed by dietians. According to the results of this survey, many and urgent problems need to be addressed improve the quality of school foodservice . Lunchroom setups, effective personnel management and expenses, recipes standardization, serving size control and regular checking and repairing of equipments are all problems to be addressed.
