BACKGROUND/OBJECTIVES: Eating-out among Korean people has become an important part of modern lifestyle due to tremendous growth of the food service industry and various social and economic changes. This study examined trends in meal patterns and meal sources while eating-out among Korean adults aged 19 years and older. SUBJECTS/METHODS: Data were from the 1998-2012 KNHNES (Korea National Health and Nutrition Examination Survey) by the 24-hour dietary recall method. This study included 55,718 adults aged 19 years and older. For analysis of eating-out frequency, data were categorized by source of meals and serving place. RESULTS: Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lower than that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals more frequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370 mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intake from eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. CONCLUSIONS: As eating-out has grown in popularity, greater recognition of public health and nutritional education aimed at promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns, individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.

Microbiological quality of packaged meals (Dosirak) was assessed in three operations under the both conditions of actual food processing and simulated time-temperature. Time and temperature data indicated that all the phases after cooking were critical for microbiological quality control. Microbiological test results by simulated time-temperature conditions revealed that microbiological quality of packaged meals decreased as the storage time and temperature increase. Delivery practices without refrigeration in summer and hot-holding below $60^{\circ}C$ in supermarket were crucial in microbiological quality control.

This study was to investigate the food habits and the dietary behaviors of university students. Questionnaires were completed by 492 students in five different departments. The data were analyzed by SAS program. The results are summarized as follows: Fifty(10.2%) of respondents were vegetarians, 81(16.4%) were heavy meat eaters and all the others were light meat eaters. All students had their biggest meal at supper. Three hundred and ninety-three(79.9%) of the respondents usually had rice for breakfast. Three hundred -sixteen(64.2%) ate 3 meals a day, 155(31.5%) ate 2 meals and all the others ate 1 meal or more than 3 meals. The length of mealtime was 30 minutes in 268(54.5%), 10 minutes in 209(42.5%) and more than 1 hour in all the others. Respondents considered taste the most important meal factor with nutrition, hygiene, and amount ranked accordingly. A majority(63.0%) of respondents ate occasionally ate between meals, while 28.1% snacked frequently, and 8.9% ate no snacks. Although nutrition dept. students had studied nutrition subject, some results of nutrition dept. students were desirable and others were undesirable in dietary behaviors. Therefore they should have a nutritional education program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.

The purpose of this study was to identify differences in dietary behavior in Korean and Chinese female university students and investigate factors that influence dietary behavior. A total of 447 female university students in Korea and China were surveyed between June 27 and August 30, 2016. The data were analyzed using $x^2$ test, t-test, one way ANOVA, and multivariate logistic regression analysis. Among Korean female university students, those who skipped breakfast were 26.18 times (95% CI: 5.421-126.407) more likely to be at a low-level stage for balanced diets than those who did not skip breakfast. In addition, compared to Korean female university students who did not eat late-night meals, those who ate late-night meals were 3.15 times (95% CI: 1.28-7.768) more likely to be at a low-level stage for balanced diets. Compared to Chinese female university students who did not skip breakfast, those who skipped breakfast were 4.22 times (95% CI: 1.865-9.551) more likely to be at a low-level stage for balanced diets. Compared to the Chinese female university students who did not stay up all night, those who stayed up all night were 5.25 times (95% CI: 1.712-16.074) to be in the preparation stage. The study results show that some factors that influence stage changes in balanced diets in Korean female university students were skipping breakfast and eating late-night meals. Therefore, it is recommended that solutions for improving the behavior of late-night meals and skipping breakfast, which are factors influencing stage changes in balanced diets should be strategically performed according to dietary behavior stages.

This study investigated Balgis (the record of the court)in the Joseon Dynasty pertaining to table settings for Sangsik (the meals for the dead). Sangsik are the records of daily meals for kings and key figures. In this study,14 pieces of Sangsikbalgi from 1890 to 1920, including two pieces from an unspecified period, were investigated to determine the composition and types of daily meals in the court. Meals consisted of a minimum of 10 dishes to a maximum 21 dishes, which basically included rice and soup. 'Jochi' was the term to refer to jjigae (stew) in the court. In Sangsikbalgi Bokgi, Gamjang, Jochi, Jjim, Suk, and Cho were all considered Jochi, which were recorded before Jeok or Jeon, where the side dishes were listed after rice and soup. This corresponded with the record of the royal tables in Wonhaeng-Ulmyo-Jeongri-Uigwe (圓行乙卯整理儀軌), in which Jochi included Jabjangjeon, Bokgi, Jabjang, and Cho. Whitebait and fruit, which are used as ingredients for Tang (soup) and Jeon, showed seasonal characteristics however, no other observed dishes showed seasonal variability. Additionally, beef and internal organs of animals were frequently used,regardless of seasons. When dishes in Sangsik were classified into basic dishes and additional cheop dishes (side dishes) based on Siuijeonseo (are recipe book of unknown authorship written in the late Joseon Dynasty), from five to nine Cheop dishes were set on the table, with seven being most common. Further comprehensive study needs to be conducted through undisclosed documents and private collections. Moreover, additional study of Judarye (anestral rites during the day for the royal) and cooking methods that were not investigated in detail in this study are needed.

The aim of this study was to provide descriptive information on meal and snack patterns and to investigate snacks in relation to energy intake and food choice according to the meal patterns of employed people in Korea. 683 employed people (292 males, 391 females) were interviewed to collect one day dietary data by using 24-h dietary recall. A recorded day was divided into 3 meal and 3 snack periods by the respondent's criteria and the time of consumption. To analyze the eating pattern participants were divided as the more frequent snack eaters (MFSE) and the less frequent snack eaters (LFSE). They were also categorized into 6 groups according to the frequency of all eating occasions. The common meal pattern in nearly half of the subjects (47.6%) was composed of three meals plus one or two snacks per day. A trend of an increasing the number of snacks in between main meals emerges, although the conventional meal pattern is still retained in most employed Korean adults. Women, aged 30-39, and urban residents, had a higher number of being MFSE than LFSE. Increasing eating occasions was associated with higher energy, protein, and carbohydrate intakes, with the exception of fat intakes. 16.8% of the total daily energy intake came from snack consumption, while the 3 main meals contributed 83.2%. Energy and macronutrient intakes from snacks in the MFSE were significantly higher than the LFSE. Instant coffee was the most popular snack in the morning and afternoon, whereas heavy snacks and alcohol were more frequently consumed by both of the meal skipper groups ($\leq$2M+2,3S and $\leq$2M+0,1S) in the evening. In conclusion, meal pattern is changing to reflect an increase of more snacks between the three main meals. Meal and snack patterns may be markers for the energy and macronutrient intakes of employed people in Korea.

BACKGROUND/OBJECTIVES: School meals are not just meals consumed at school, they are part of the culture, education, and life experience at school. Nevertheless, few studies have revealed the influence of school meals on students' school lives. The purpose of this study was to investigate the effect of satisfaction with the school meal program on students' school happiness. SUBJECTS/METHODS: A survey conducted in December 2015 asked 2,336 students (1,062 elementary school students, 880 middle school students, and 394 high school students) about their satisfaction with the school meal program and their school happiness. Multiple regression analyses were used to examine the relation between the students' school meal satisfaction and their happiness level. RESULTS: The average level of satisfaction with school meals of elementary school students was 4.1 out of 5 points, comparatively higher than that of middle and high school students, with a significant difference between school levels (P < 0.001). In addition, school happiness, as well as overall happiness, of elementary school students was higher than that of middle and high school students (P < 0.001). The school meal operation factor (0.232, P < 0.001) had the most influence on students' school happiness, followed by the school meal environment factor (0.219, P < 0.001) and school meal quality factor (0.136, P < 0.001). Overall satisfaction (0.097, P = 0.001) and school meal hygiene factor (0.095, P = 0.001) also had significant influences on students' school happiness. CONCLUSIONS: Students' satisfaction with the school meal program was related to their school happiness. Therefore, plans to enhance students' satisfaction with a school meal program needs to be implemented, with emphasis on placing a priority on school meal operation and school environment factors, in order to improve students' level of happiness.

One of the most pressing problems of the day in our household economy is the scientific improvement of meal management, which has direct bearings on the efficiency of housewives, domestic economy, and health care for the whole family. The concern of this paper is to investigate the current meal management situation in which more than three hundred housewives in Seoul find themselves, and to propose a tentative plan for its improvement. The result of the investigation is summarized as follows : 1) The number of families with old-fashioned kitchens forms a percentage of 30.3 ; only 4.3 percent of them have waterworks and drainage system. 2) The number of families equipped with cooking machines and utensils constitutes 51.2 percent ; that of those without cooking machines reaches the high percentage of 92.8. 3) The expense for daily meals amounts to 37.9 percent of the whole domestic expenses. the number of those who prepare daily meals without any planning comprises 78 percent. It is from habit that 60.5 percent of them make no workable plan for their meals. 4) The frequency of housewives doing daily marketing is comparatively high. 5) The time spent in preparing and clearing the table is 280.4 minutes a day on the average. 6) In preparing daily meals the low income bracket tends to keep expense as low as possible, while the high income bracket is chiefly concerned with taste. 7) The frequency of home cooking is on the increase as the housewives grow older, especially in the large families with housemaids. 8) In most cases housewives do the cooking for themselves; the high income brackets have housemaids do the cooking. The number of husbands who help their wives do kitchen work a small percentage of 10-14. 9) The simplification of kitchen work presupposes the simplification of the daily cooking, the improvement of the structure and equipment of the kitchen, and a good help of the whole family.

This study was conducted to find the nutrition status and the effects of nutrition education by comparing the condition of the subjects before and after the education among elementary students attending a community child center(CCC). The subjects of the study were 70 elementary school students in CCC in Donggu, Ulsan as a control group compared to other 87 elementary students in the same age and the same area. The result were as follows. The students in CCC showed higher rate of skipping breakfasts and less rate of having snacks, compared with control students. Also they showed lower scores of both nutrition knowledge and dietary belief. The CCC group had higher rate of skipping meals, especially on weekends(72.9%), and showed less nutrient intakes than the control group. After the nutrition education, nutrition knowledge and dietary beliefs of the nutrition group showed better results but no difference in their dietary attitudes. The education did not make significant differences in the rate of skipping meals and in the nutrient intakes. Considering all the results above, an adequate plan for providing meals is required as well as a nutrition education for improvement of the poor nutrition condition of children in CCC.
