BACKGROUND/OBJECTIVES: Korean ordinary diets are referred to be good for human health in worldwide. However it is uncertain whether they provide microminerals enough for growth and health of teenagers. A main purpose of this study was to identify micromineral contents in school meals. MATERIALS/METHODS: The fifty cuisines were collected from elementary schools and middle schools in Gyeongnam area. The contents of Fe, Zn, Cu and Mn among microminerals were analyzed by using ICP-OES method. Data were expressed as mean, standard deviation and range value and linear regression analysis performed. RESULTS: Fe level of Pangibuseotpaprika-salad was the highest among side-dishes (average $346.6{\mu}g$) and Zn level of Sullung-tang was highest among soups (average $229.1{\mu}g$). Cu level of Buchu-kimchi was the highest among kimchies (average $217.5{\mu}g$) and Mn level of Gumeunkongyangnyum-gui was highest among side-dishes (average $198.4{\mu}g$). Generally cooked-rices as main dish had relative smaller amounts of microminerals than the other cuisines. The results showed that the ratio of Cu : Fe : Zn was approximately 12 : 4 : 1 and the relationship between Fe versus Zn or Fe versus Cu was significantly positive. CONCLUSION: Comparing to Korean Dietary Recommended Intakes (KDRI) level, school meals provided not sufficient amount (<25% DRI) of Fe, Zn or Mn, while they did excessive amount (>125% DRI) of Cu.

Dental caries is one of the main factors to cause the teeth to be lost. Diet is the important factor in the development of dental caries. Today, Dental plaque control, Fluoride to pical application, Fissure sealing and Diet control are used to prevent dental caries. By the five day diet diary, the author surveyed the food in take of 600 infants aged from 10 to 12 in the subures of Seoul. Using the cariogenic food intake analysis form, the detergent food intake analysis form and the basic food intake analysis form, the data were collected, analysed and discussed. After discussing the results, the author concluded as follows : 1. The intake frequency of meals per day was 4.91 times, of which 2.74 times taken at meals and 2.17 times at between meals. Girls(5.00) had taken more times than boys(4.69) at meals an between meals. 2. The intake frequency of cariogenic food per day was 1.93 times, Liquid cariogenic food was taken 0.05 times at meals, and 0.58 times at between meals. Solid cariogenic food was taken 0.05 times at meals, and 0.08 times at between meals. Girls(1.67) had taken cariogenic food more times than boys(1.46). 3. The percentage of intake without detergent food of each intake time per head per day was 71.62% at meals, and 85.7% at between meals. The highest percentage was at evening meals. Boys(44.00%) had taken more detergent food than girls(56.71%). 4. Both boys and girls had the basic food intake taken enough only in 2nd group of basic food, lacking in the other 4 groups. Girls had taken the basic food comparatively more times than boys.

The purpose of this study was to investigate the perception of the quality of school meals by parents of kindergarten children in Seoul, analyze the acceptance price and the optimal school meal cost using PSM (price sensitivity measurement) techniques, and provide basic data for improving the quality of kindergarten meals. The survey was conducted using descriptive statistics and PSM analysis of the responses of 1,272 parents of 779 kindergarten children belonging to the Seoul Metropolitan Office of Education from April to May 2021 and prior research analysis related to kindergarten meals. 74.1% of the parents surveyed were women, with 61% of children attending kindergartens attached to elementary schools, followed by private kindergartens (28.9%) and public kindergartens (10.1%). According to a study of the quality of meals, private kindergarten parents are highly satisfied with all the quality attributes of meals, such as "sanitation of dining environment" and "nutritionally balanced food" (p<0.001, p<0.01). The analysis of the acceptance price range and the optimal price for school meals showed that there was no significant variation based on the type of kindergarten establishment, with parents' acceptance price range ranging from 3,596 won to 4,454 won with an optimal price of 3,948 won.

Predicting the number of meals in a foodservice organization is an important decision-making process that is essential for successful food production, such as reducing the amount of residue, preventing menu quality deterioration, and preventing rising costs. Compared to other demand forecasts, the menu of dietary personnel includes diverse menus, and various dietary supplements include a range of side dishes. In addition to the menus, diverse subjects for prediction are very difficult problems. Therefore, the purpose of this study was to establish a method for predicting the number of meals including predictive modeling and considering various factors in addition to menus which are actually used in the field. For this purpose, 63 variables in eight categories such as the daily available number of people for the meals, the number of people in the time series, daily menu details, weekdays or seasons, days before or after holidays, weather and temperature, holidays or year-end, and events were identified as decision variables. An ensemble model using six prediction models was then constructed to predict the number of meals. As a result, the prediction error rate was reduced from 10%~11% to approximately 6~7%, which was expected to reduce the residual amount by approximately 40%.

The purpose of this study is to analyze the family's meals of the daily time use and to examine how shared meals time together with family is influenced by socio-demographic variables. The Time Use Survey data collected by Korean National Statistical Office in 2009 is used. Among the total sample of 21,000 individuals, 9,179 samples who are married, aged from 20 to 59 years old and non-farmers are selected for analysis. The statistical methods are frequency, percentage, and censored regression model. The following is a summary of the major findings. The first, compared with the research results in 1999 and 2004, the time use of meals by adults is longer. But average time of family meals decreases and rates of family meals participants 2009 decrease 5.6% than 1999. Secondly, the family meals time increases from about 36 minutes on weekdays to about an hours at weekends. Regardless of the day, the women's family meals time is longer than that of men's. Thirdly, the influencing factors on family meals are sex, age, education, presence or absence of spouses, monthly income, weekly working hours and presence or absence of preschoolers. And the magnitude of gender differences in daily shared meals is not particularly large except in the case of some socio-demographic variables. Regardless of the day, women's family meals time is more affected by either dual-earner status or monthly income than that of men's.

BACKGROUND/OBJECTIVES: Recently, there has been an increased interest in the importance of family meals on children's health and nutrition. This study aims to examine if the eating habits and eating behaviors of children are different according to the frequency of family dinners. SUBJECTS/METHODS: The subjects were third-grade students from 70 elementary schools in 17 cities nationwide. A two-stage stratified cluster sampling was employed. The survey questionnaire was composed of items that examined the general characteristics, family meals, eating habits, eating behaviors, and environmental influence on children's eating. The subjects responded to a self-reported questionnaire. Excluding the incomplete responses, the data (n = 3,435) were analyzed using ${\chi}^2$-test or t-test. RESULTS: The group that had more frequent family dinners (${\geq}$ 5 days/week, 63.4%), compared to those that had less (${\leq}$ 4 days/week, 36.6%), showed better eating habits, such as eating meals regularly, performing desirable behaviors during meals, having breakfast frequently, having breakfast with family members (P < 0.001), and not eating only what he or she likes (P < 0.05). Those who had more frequent family dinners also consumed healthy foods with more frequency, including protein foods, dairy products, grains, vegetables, seaweeds (P < 0.001), and fruits (P < 0.01). However, unhealthy eating behaviors (e.g., eating fatty foods, salty foods, sweets, etc.) were not significantly different by the frequency of family dinners. CONCLUSIONS: Having dinner frequently with family members was associated with more desirable eating habits and with healthy eating behaviors in young children. Thus nutrition education might be planned to promote family dinners, by emphasizing the benefits of having family meals on children's health and nutrition and making more opportunities for family meals.
