  • This study was performed to weigh the average meal portion sizes served for preschoolers by kindergarten teacher. The subjects were 53 teachers from 8 kindergartens, which are random sampled by meal service number. Using the weighing method assessed the meal portion sizes of food items at lunch. The data was complied by performing $\chi^2-test$ using SPSS WIN 11.0. The result was as followed: 98.0% of teacher agreed with the meal service because of 'better food habit and table etiquette'(68.0%), 'health promotion with balanced diet'(22.0%), 'owing to extending school time'(6.0%) and 'demand of parents'(2.0%). Preschooler eat lunch at class (84.9%) and meal serving size was decided by teacher (79.2%). Teachers thought that they know very well about portion size 3.8%, 96.2% of teacher thought that they don't know much about portion size. Portion size were not significantly different by food tray types but there was much different (almost 100%) compared with minimum and maximum within dishes. Most average portion size was not met dietary reference intake except cooked rice, soups and fish cutlet. Working experience effected on portion size. More served, more working experienced of teacher. For example Bulgogi was served 26.8 g by teacher who has over 6 years working experience compared with 2-6 years (20.4 g) and less than 2 years (17.1 g) (p < 0.01). Spinach portion size was significantly different by teacher's working experience (p < 0.01). Portion size were not significantly different by preschooler's age. The reference of dietary for preschooler was different by age, but teachers served meal by their experience. According to the results of this study, it is necessary to educate meal portion size for kindergarten teacher who take charge in meal serving. To provide guidance to teacher about reasonable portion sizes for preschoolers, teacher need to take nutrition education about meal service and child nutrition in college. This study would be useful to those who plan meals for preschoolers and to researchers studying dietary intakes of preschooler.

  • Objectives: This study was performed to set easily applicable portion sizes by sex and age for children at the Community Child Centers (CCC) in Korea. Methods: Considering the age and gender specific energy level at Target Patterns for children aged 6-18 years, which were suggested as a part of the 2010 Korean Food Guidance System (KFGS), we set three meal sizes. We reclassified the recommended daily servings of Grains, Meat fish eggs beans and Vegetables group at Target Patterns into three meal sizes, and then calculated the recommended serving per meal. Each proposed amount of food per meal was calculated based on serving size of foods commonly eaten at KFGS, which was then allocated to five meal components; rice, soup stew, protein and vegetable side-dishes and Kimchi. Each proposed amount of food per meal was applied to 173 menus' recipes from CANpro 3.0 as main ingredient's amounts. We cooked the 173 menus at the medium size and measured their weights after cooking. Results: Each recommended serving per meal was 0.75, 0.9 and 1.2 for Grains; 1.2, 1.6 and 2.4 for Meat fish eggs beans; 2, 2.4 and 2.8 for Vegetables by meal sizes. Among five meal components, the ratio of small and large to medium size was 1/5 less and 1/3 more for rice and 1/3 less and 1/3 more for soup stew, protein side-dish and Kimchi, respectively. We suggested the same amount for a vegetable side-dish to encourage vegetable intake. Proper portion sizes per meal of medium were rice 190 g, soup stew 210 g (solid ingredients 60 g), protein side-dish 100 g (meat eggs beans) and 70 g (fish), vegetable side-dish 80g and Kimchi 30 g. Conclusions: Proper portion size per meal suggested in this study may be useful at the CCC where dietitians are not available and the approach could be applicable to the other types of meal services.

  • The study was aimed to investigate the operational meal costs by kindergarten size in Seoul and to analyze recognition for optimal meal prices. A survey (31.6% recovery rate) was conducted on all kindergartens (779 kindergartens) in Seoul on April 2021 using descriptive analysis, t-test, and dispersion method. A price sensitivity measurement (psm) method was used to determine optimal meal prices. Result showed an average food cost for kindergartens of 2,647 won, an average labor cost of 605 won, an average operating cost of 146 won, and the total meal cost of 3,506 won. Total meal cost decreased with increasing kindergarten size (p<0.001). On the other hand, kindergartens with more students decreased the ratio of food cost to total meal cost, and operating cost and labor costs (p<0.001) increased. The optimal price of kindergarten operators' meal cost (OPP) was KRW 3,673. Furthermore, the analysis showed the sensitivity of operators' meal costs to kindergarten size was insignificant.

  • The purpose of the study was to compare the satisfaction level on hospital meal size and actual intake rate of hospital foods between elderly and middle aged patients. Sixty one middle aged and one hundered thirty two elderly patients were surveyed on the foods served in the hospital-rice, soup, meat/fish, vegetable, kimchi and daily products. Compared to the middle aged patients, the more elderly thought the serving size of rice was too big(p<0.05), and those of soup, meat/fish and kimchi tended to be too big. There was no difference in the satisfaction level on the serving size of vegetable dish between two age groups. In actual intake rates of hospital meal there were no significant differences between the elderly and middle aged patients. However, the elderly male ate significantly(p<0.05) less amount of rice than the middle aged male and the elderly female ate significantly(p<0.01) less amount of meat/fish then the middle aged female. Satisfaction levels and actual intake rates were significantly correlated in all food items.

  • Sixteen mature sheep were fed chaffed orchardgrass hay once a day. Jaw movement of the sheep was recorded for 24 hours before slaughter. Four sheep were slaughtered either prior to eating, 2, 8 or 16 hours after the commencement of eating to measure digesta pool size and particle size distribution in the reticulo-rumen. Eating time was restricted to 120 minutes. Rumination time and actual chewing time during rumination increased with time after the meal. Mean dry matter (DM) pool size before and 2 hours after the meal were 1.36 and 2.45 times of DM intake, respectively. The proportion of large particle (>1.18 mm; LP) in the DM ingested during the meal was caculated to be about 70%. The mean DM and LP pool sizes per DM intake and the mean proportion of LP in the DM pool decreased with time after the meal. There were close negative relationships between either DM or LP pool sizes per DM intake and the chewing activities either expressed as time spent rumination, actual chewing time during rumination or total actual chewing time(total of eating time and actual chewing time during rumination). The difference between DM intake and LP pool size were assumed to be LP degradation in the present experiment, and correlated positively with the chewing activities. A large proportion of the digesta load was comprised of small particles, in excess of the daily intake.

  • Most commonly occurring predacious fungus Arthrobotrys oligospora showed great variation in size and shape of conidia on some media. The formation of larger conidia was recorded on beef extract and nutrient agar media. The length of conidia in Richard's YPSS, Sabouraud's, PDA and com meal agar media was of medium size while smaller conidia were produced on Czapek's, Jensen's, Martin's medium. Maximum width of conidia was recorded on YPSS medium followed by Sabouraud's medium. The average size of spores on nematode infested com meal agar medium was slightly increased than those on com meal agar medium.

  • In this study, we attempted to analyze the status of meal nutritional management at daycare centers and determine whether the need for improvement varies depending on their size. We divided into two groups based on the size of foodservice facilities. If meals for more than 50 people are provided at a time, they are classified as large-scale facilities (Large-scale group). If they are smaller, they are classified as small-scale facilities (Small-scale group). Dietitians visited each daycare center and checked 5 categories and 14 items. When comparing 5 categories, scores in the Small-scale group scored higher than those in the Large-scale group for 'Menu utilization' category. As a result of comparing the detailed 14 items, the scores of 'Indicate dietary information', 'Use menus suitable for those who are eligible for meals', and 'Posting menus by age in public places at foodservice facilities' were higher in the Small-scale group than in the Large-scale group. As such, there are differences in meal nutritional management according to the size of children's foodservice facilities therefore, it was found that customized education and management were needed according to the facilities' size.

  • Drastic changes were observed in egg chamber during oogenesis of Aedes togoi immediately after blood meal. The egg chamber, in which the oocyte remains at previtellogenic stage before blood meal, shows very little change in size even for 3 days after emergence but increased 25 folds in volume within 60 hours after blood meal, presumably due to rapid yolk formation. Upto 6 hours after blood meal structures considered to be the precursor of the yolk granules were not observed in the space between follicle cells and oocyte. Vitelline bodies, which are similar to dense bodies secreted from follicle cells, appeared in the space at 10 hours after blood meal. Although vitelline bodies were fused to form vitelline layer, these bodies seem to contribute to the formation of yolk granules. Nurse cells are connected to oocytes by cytoplasmic bridge before blood meal, but the cells are absorbed into oocyte at 6 hours after blood meal.

  • This study was conducted to provide basic data for evolving a strategy for the development of Vietnam's customized HMR program and formulating a marketing strategy by analyzing the characteristics and variations of HMR consumption behavior by household size. The results of the analysis were as follows: The number of single households using HMR as a general meal at home was higher than multiple-person households. Moreover, there was a high preference for 'ready to heat' and 'ready to eat' products, which are relatively easy to cook and prepare. It was observed that single households preferred department stores, hypermarkets, and convenience stores for purchasing HMR when compared to multiple households, and that single households preferred to acquire information through TV/radio and internet advertisements. Among the HMR selection attributes, single households valued taste, quantity, price, preparation process, preparation time, and ease of storage as important. Reflecting on the results of this study, when developing HMR in Vietnam, it is necessary to develop a product that can nutritionally replace the general meal with a focus on convenience. In addition, there is a need for products that possess various attributes such as convenience, health, and eco-friendliness.

  • 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.
