This study investigated the situation of eating meals to identify factors influencing skipping breakfast and types of foods consumed for breakfast among adolescents classified by household type. Adolescents were found to consume mainly homemade meals for breakfast and dinner while consuming institutional foodservice at school for lunch. Percentage of skipping meals among adolescents was different by time of meals, and they skipped meals due to lack of time, which was different according to household type. Main food for breakfast was rice, and percentage of skipping breakfast was the highest in single parent households. Satisfaction of food-related life was lowest in grandparent households. Especially, satisfaction was highest if they had rice for breakfast. For influencing factors on skipping breakfast, social support, eating regularly, concern for origin, and single parent household were found to be significant. For influencing factors on types of foods consumed for breakfast, eating regularly, exercise, satisfaction of food-related life, and concern for food safety among adolescents were found to be significant. If adolescents in grandparent households had rice, they were less likely to skip breakfast.

Consuming regular meals has been studied in relation to better health, while higher regularity of eating-out has been linked to obesity. This study examined whether acculturation was associated with regularity of meals, eating-out, and overweight in Korean Americans. Pre-tested questionnaires were mailed to a U.S. national sample with Korean American surnames, and 55% of the deliverable sample responded, producing 356 usable questionnaires. Acculturation was measured using a two-culture matrix model and Gordon's theoretical work, and showed there were three distinct groups (acculturated, bicultural, and traditional). Only 36% reported that they regularly ate three meals a day. Breakfast was the least frequent meal of the day with 43% reporting eating breakfast everyday. More than half (58%) reported that they usually eat out or get take-out food at least once a week. After controlling for age, sex, income, education, and working status, higher acculturation was related to greater regularity of eating-out, but not meal regularity. A total of 28% of men and 6% of women were overweight (BMI>25), and there were significant and positive relationships between body weight status and acculturation in men but not women. However, no significant relationships between frequency of meals and eating-out and overweight status were present. This study did not find significant relationships of meal regularity and eating-out with body weight, however, given the positive relationship between acculturation and eating-out among the subjects and the well-established relationship between eating-out and obesity, nutrition education about skipping meals and eating-for Korean Americans may be useful to prevent such relationships from developing.

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%.

This study was performed to describe the perceptions of the family mealtime environment in preadolescents, and to determine the frequency of family meals and whether the mealtime environment is associated with nutrient intake. Surveys and 24-hour dietary recalls were completed by 197 children, ages 11 to 12, in elementary schools in the Incheon area. We assessed family meal frequency and the perceptions of the family meal environment with respect to priority, atmosphere, and family mealtime structure. The subject response frequencies and correlations among perceptions of the family mealtime environment, as well as the frequency of family meals and nutrient intake, were analyzed. Having a greater priority for family meals was associated with an increased frequency of family mealtimes. An enjoyable family meal environment was positively correlated with increases in nutrient intake. From the results of this study, we suggest that consideration be placed on opportunities to design nutrition promotion strategies that target families and their children, with respect to promoting family mealtimes and overcoming the barriers to having family meals.

Nutrition is an essential component of total adolescent health care. Two important changes occurring during adolescence can cause a crisis in the teenager's nutritional needs. First, growth in height, weight, and body component is greater and more rapid than at any time since infancy. Second, an adolescent's eating habits may change from regular meals prepared at home to irregular meals, skipped meals, and nutrition-poor snacks and fast-food meals. Adolescents have been found to have the highest prevalence of any age group of an unsatisfactory nutritional status. To understand the nutritional requirements of the adolescent, health practitioners should be aware of the intensity and timing of the adolescent growth spurt, the differences in the growth spurt between males and females, and the individual variation in timing of the growth spurt from teenager to teenager.

The purpose of this study was to investigate the relationship between the eating habits and social behavior of preschool children. Six hundred twenty seven children ranging in age from 4 to 7 and their mothers were asked to complete a questionnaire assessing the children's eating habits and kindergarten teachers were asked to rate the social behavior of their preschool children. The eating habits of children positively correlated to those of their mothers, primarily in meal regularity, breakfast frequency, unbalanced meals, overeating, eating delivery food and food preferences. The results showed that 33% of preschool children always had unbalanced meals and 50% sometimes had them. Children who had ice cream, cake, carbonated drinks or cookies as snacks more often, tend to have meals irregularly because they favored sweets and were possibly induced to have unbalanced meals. Sixty five percent of the children were graded as good in terms of having healthy eating habits and had good social behavior. The results indicate that the eating habits of children are related to problem behavior, especially social withdrawal and anxiety. That is, children who have undesirable eating habits are likely to be anxious or socially withdrawn.

This study researched the microbial change of quality according to various phases of product flow of Dongtae-Jeon (a pan-fried dish) and rolled egg in packaged meals. In order to carry out the study, the time required, temperature, water activity and microbial quality were measured at various phases of production flow of Dongtae-Jeon and rolled egg in packaged meals, and the effects of these factors on microbial multiplication was analyzed. According to the phases in product flow of Dongtae-Jeon, it was shown that the time required is 12.5hrs and water activity is distributed 0.932-0.980. These conditions were suitable for microbial multiplication. According to the phases in product flow of rolled egg, it was shown that the time required is 3.3hrs. In addition, qualitative analysis of pathogenic microorganisms (Salmonella spp., Vibrio parahaemolyticus, Staphylococcus aureus) detected no such microorganisms in any of the samples.

The purpose of this study is to introduce a more efficient forecasting technique, which could help result the reduction of cost in removing the waste of airline in-flight meals. We will use a neural network approach known to many researchers as the “Outstanding Forecasting Technique”. We employed a multi-layer perceptron neural network using a backpropagation algorithm. We also suggested using other related information to improve the forecasting performances of neural networks. We divided the data into three sets, which are training data set, cross validation data set, and test data set. Time lag variables are still employed in our model according to the general view of time series forecasting. We measured the accuracy of our model by “Mean Square Error”(MSE). The suggested model proved most excellent in serving economy class in-flight meals. Forecasting the exact amount of meals needed for each airline could reduce the waste of meals and therefore, lead to the reduction of cost. Better yet, it could enhance the cost competition of each airline, keep the schedules on time, and lead to better service.

Purpose: This study investigated the salt and sodium content of lunch meals served at foodservice center for children in Gyeongsan-si, Gyeongsangbuk-do. Methods: Five foodservice centers for children registered at Center for Children's Foodservice Management were investigated for salt and sodium content and salt content contributing rate per meal. Results: Average salt content of every meal was $1.78{\pm}0.54g$, and average sodium content was $680.99{\pm}175.97mg$. The 98 of 100 meals served in 5 foodservice centers for children exceeded the dietary reference intakes for Koreans' recommendation for adequate intake of sodium per meal of 333 mg. The highest sodium content was 1,369.85 mg. Samples from lunch meals were classified into 14 food items and investigated for one serving size, salinity, salt and sodium content. Total average salinity was 0.31%, kimchi (0.49%), followed by soup (0.45%), hard-boiled foods (0.39%), stir-fried foods (0.39%), and fresh-vegetables (0.32%). Total average salt content was 0.39 g, the most salty dishes were one-dish rice noodles, followed by soup (0.65 g), hard-boiled foods (0.49 g), stir-fried foods (0.48 g), and broth stew (0.43 g). Samples from lunch meals were classified into 6 menu groups, including cooked rice, one-dish rice noodles, soup stew, main dish, side dish, and kimchi. Contributing rate for total average salt content was high in one-dish rice noodles (48.97%), soup stew (38.47%), main dish (27.28%), side dish (21.02%), kimchi (18.56%), and cooked rice (3.95%). Conclusion: These results can be useful for reducing total dietary sodium content to less than 333 mg in children who are provided lunch meals at foodservice centers. To achieve this goal, development of low-sodium recipes, and nutrition education for foodservice employees is required.

Food goods traded between Korea and Japan during the first term of the Cho Sun era included Omija (fruit of the Maximowiczia chinensis), Jat (pine nuts), Insam (Jinseng), rice, and beans as exports ; and pepper, sugar, and medicinal stuffs as imports. The trade between Korea and Japan was a result of Japanese envoies' visiting. The official number of Japanese envoies who had exchanges with Koreans were two thousand people a year. Once the Japanese entered Korea, they did not need to pay for their living expenses for the length of their visit because the Cho Sun government bore the whole expense. The Cho Sun government gave formal receptions to them, which included daily meals as well as banquet style meals. The daily meals included Jo-ban (breakfast), Jo-seok-ban (breakfast and dinner), and Ju-jeom-sim (lunch). Meals were served four times a day. The banquet style meals included Sam-po-yeon (a banquet that was held in Sam-po), Kyong-joong-young-jeon-yeon (a farewell banquet, and a welcome banquet that was held in Seoul), Jyu-bong-bae (to offer a guest a drink by day), No-yeon (a banquet that was held on the street), Kwol-nae-yeon (a banquet that was held within the Royal Court). It also included Ye-jo-yeon (a banquet that was held in Ye-jo), and Myong-il-yeon (a banquet that was held on a national holiday). The banquet style meals were composed of Ceon-tack (to set a table for dinner), Sang-hwa (a flower that was put on the food), Kwan-hwa (to offer a flower when a banquet was held), Ju-5-jan (the fifth wine glass), Dae-seon (meat), and music.
