This study was conducted to characterize changes in the meal structure of Korean children in terms of temporal and spatial dimensions. The data of 1,891 and 1,627 school-aged children and adolescents extracted respectively from the 1998 and 2009 Korea National Health and Nutrition Examination Surveys were analyzed by gender, age group, and residential area. From 1998 to 2009, the total eating events increased from 4.3 to 4.6 (p = 0.001); the average number of meal intake decreased from 2.8 to 2.7 (p < 0.001) while that of snack intake increased from 1.5 to 1.9 (p < 0.001). The prevalence of "3 meals a day" pattern tended to decrease while that of "2 meals a day" pattern increased over the years. Especially, the "2 meals a day" pattern with "lunch + dinner" increased from 13% in 1998 to 20% in 2009. The percentage of eating breakfast or dinner at home decreased over the years. These results indicate that over the last decade, "destructuration" occurred in Korean children's meal structure in terms of temporal and spatial dimensions. Especially, such alteration was more distinctive in male than female and in the high school-aged group than the elementary or middle school-aged groups. Overall, the difference of meal structure between genders and residential areas became smaller while the difference among age groups became larger over the years.

본 연구는 국내에서 사용되고 있는 몇 가지 단백질 원료사료를 사용하여 단백질 fraction과 in situ 단백질 분해율을 구한 다음 이들 사이에서의 상관관계를 살펴보고자 실시하였다. 원료사료는 대두박, 콘글루텐, 면실박, 카폭박 및 임자박이었다. 단백질 fraction은 CNCPS에서 제시하는 방법으로 구하였으며, in situ 단백질 분해율은 캐뉼라가 장착된 홀스타인 거세우 3두를 이용하여 반추위에서 원료사료를 4, 8, 12 및 24시간 배양하여 구하였다. 단백질 fraction 중 A fraction은 카폭박이 14.6%로 가장 높았고, 콘글루텐이 0.6%로 가장 낮았다(P<0.05). B1 fraction은 대두박이 8.27%로 가장 높았으며, B2 fraction은 대두박과 면실박이 74%로 가장 높았다. B3 fraction은 임자박이 40%로 다른 원료사료에 비교해 뚜렷하게 높았다. C fraction은 콘글루텐이 약 42.5%로 가장 높았다. In situ 조단백질 분해율은 대두박이 98%로 가장 높았고, 콘글루텐은 28%로 가장 낮았다. 단백질 fraction과 in situ 분해율 사이의 상관관계를 보면, 쉽게 용해되는 부분(A, B1 fraction vs a값) 사이에, in situ 조단백질 분해율과 소화가능한 단백질 fraction 사이에, 그리고 in situ 조단백질 분해율에서 a값을 제외한 값과 B2+B3 fraction 사이에는 상관관계가 높았다(P<0.01). 본 연구결과에 의하면, 단백질 fraction은 원료사료의 반추위내 분해율을 추정하는 데 이용될 수 있을 것으로 사료되며, 앞으로 더 정확한 평가를 위해서는 더 많은 원료사료에 대한 분석이 필요하다고 본다.

BACKGROUND/OBJECTIVES: This study aimed to compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students. SUBJECTS/METHODS: A total of 1,441 elementary, middle, and high school students attending 58 schools in Gyeonggi-do, South Korea participated in the survey in 2015. A questionnaire and informed consent forms for students and legal guardians were sent home and completed responses were returned to the researcher. RESULTS: Approximately 58% of the students perceived the portion sizes of school meals as appropriate and 76.1% consumed almost all or all of the meals served. More elementary and middle school students than high school students consumed almost all or all of the meals (P < 0.001). A regression analysis revealed that the students with a higher dietary behavior score (P < 0.001), higher satisfaction with food service (P < 0.001), a higher environmental protection practice score (P < 0.05), and more positive attitudes toward school meals (P < 0.01) consumed significantly more meals. The provision of foods that taste good and reflecting student opinions on menus were the most important factors for increasing school meal consumption. CONCLUSIONS: To increase consumption of school meals, food service staff should provide students with quality meals and engage students in school food service. Nutrition education that emphasizes healthy eating behaviors and cafeteria environment modification that applies strategies based on behavioral economics can encourage students to consume more school meals.

Purpose: Sodium intake in school meals is very high. Accordingly, many health problems have emerged. The objective of this study was to assess school dietitian's awareness and practice of sodium contents in urban and rural locations schools and suggest sodium reduction plan in school meal service. Methods: A total of 524 nationwide school dietitians from elementary, middle, and high schools in south Korea were surveyed using questionnaires to determine their awareness and practicing behavior for reducing high-salt contents in meals. Sodium reduction plan was then suggested accordingly. Results: Most school dietitians (83%, n=436) were aware of the necessities of sodium reduction in school meals. They were aware of optimum sodium levels at 700-1000 mg. However, the percentages of dietitians who had practicing behavior of using measuring utensils for seasoning were 20.7% (n=108), 14.9% (n=78), and 13.5% (n=71) in elementary, middle, and high schools, respectively (p<0.001). Dietitians in urban elementary and middle schools had significantly (p<0.01) higher practicing behavior of using measuring utensils compared to those in rural locations. Considering low levels of soup contents with high amount of leftover, the desirable soup portions to be reduced were '50-100 mL' (n=66, 12.7%) for elementary school and '100-150 mL' for middle school (n=62, 12.0%) and high school (n=57, 11.0%, p<0.001). Conclusion: Dietitians' awareness for sodium reduction was high but their practicing behavior was relatively low. Thus, continuous efforts are required to develop reduced-sodium menu by promoting the use of measuring utensils when preparing meals and by planning no soup meal day or educating students and teachers about the importances of reducing sodium in school meals.

Purpose: This study was done to identify menstrual discomfort and dietary habits, and factors related to the menstrual discomforts. Method: Participants were 320 female middle school students in G city. The Menstrual Discomfort Questionaire(MDQ) and dietary habit lists were used as tools. Results: Factors related to MDQ were found to be the VAS scores (r=.361, p=.002), a mount of menstrual bleeding (r=.131, p=.019), height (r=.134, p=.016), adequacy of meal time (t=7.19, p=.008), consumption of milk & milk products (F=3.20, p=.042) and, hot, salty & irritant foods (f=8.01, p=.000), eating more than 3 kinds of side-dishes with each meal (F=8.32, p=.000), and various protein foods (F=5.15, p=.006). In stepwise regression, 4 variables (VAS scores, height, hot, salty & irritant foods, more than 3 kinds of side-dishes with each meal) explained $20.3\%$ of the variance in the total MDQ scores. Conclusion: Reduction of hot, salty & irritant foods and having more than 3 side-dishes with each meal would be effective in menstrual discomfort management. As well, good and, balanced dietary habits should be encouraged for early adolescent girls. To keep up with the ideal dietary habits, nutritional education & counseling should be continued. In a further study, a replication study with larger samples and more specified nutritional assessment are recommended.

The purpose of this study was to provide basic data of nutrition education to teach the right eating habit and lifestyle by investigating eating habit of students in private and public elementary schools of Kangnam and Kangbuk region. When the eating habit was investigated, there was no difference between the residential region, and school types. Depending on gender and person who cooked, there was meaningful difference in the eating habit. When the mother or father cooked for the student, his or her child had breakfast everyday, had a meal regularly, enjoyed the meal with the family, and left less food. This shows that the meal with family is a very positive factor in the formation of right eating habit. The female students tend to eat snacks, skip breakfast, have unbalanced diet, leave food, and watch TV during a meal more than the male students. Therefore, the female students need more education of eating habit. Also, not many the students usually got corrected their bad eating habits from others, and this showed that no proper guidance of their bad eating habits was done. Nevertheless, the students tried to correct their eating habits by themselves. If the schools and students' give them the proper education about eating habit, it can be more effective. Therefore, the school should teach the students and their parents the right table manner and nutrition information through a systematical curriculum. In special cases, they should teach the students individually.

Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

In this investigation, 480 high school students attending school in Seoul, Incheon were surveyed for their knowledge of seaweed and their preference of seaweed products provided during school meal service. Female students answered that they preferred seaweed more than male students. When asked to explain their preference for seaweed, most students who preferred seaweed responded 'it is tasty' (82.9%), while those that did not like seaweed responded 'I don't like the texture when chewing it and it is not tasty' (47.8%). Most students reported that they usually eat 'laver', and the number of times that they at seaweed was '3-4 times a week'. The primary place in which they ate seaweed and the place where they feel it had the best taste was a 'house'. The primary source of information regarding seaweed was mass media including TV, newspapers, magazines and the internet (48.8%). With regard to seaweed in school meals, which is offered twice a week, most students reported, 'I eat seaweed and leave it to some extent.' They perceived 'laver' to be most often provided in school meals, and 57.7% reported that their favorite seaweed meal was 'laver'. When asked why they dislike seaweed in school meals, the most common responses were 'I didn't like seaweed the first time I tried it' (27%) and 'Its taste is different from what I eat at home' (24.6%). The most common request regarding seaweed provided in school lunches was for the taste to be improved (48.2%). Evaluation of the preference for seaweed menus in school meals revealed that both males and females had higher preferences of more than 4 points for 'fried laver' and 'broiled laver'.
