The purpose of this study was to investigate the relationship between Kimchi intake and the prevalence of metabolic syndrome in Korean adults (over 19 years old), using data from the Korean National Health & Nutrition Examination Survey (KNHANES), 2007~2012. A total of 30,630 participants were analyzed in this study. Metabolic syndrome was diagnosed using the NCEP ATP III criteria standards. Out of the 30,630 participants, 8,230 (23.45%) had meatabolic syndrome. When the subjects were grouped by their Kimchi intake, those who consumed a sufficient amount (36.0~82.125 g) showed a lower prevalence of metabolic syndrome (P<0.001). However, multiple logistic regression analysis results after adjusting for sex and age, exercise status, smoking status, drinking status, energy intake, income level, occupation, area, frequency of eating-out, showed that the Kimchi intake did not significantly affect the odds ratio of metabolic syndrome. High sodium contents of Kimchi was the major cause of various cardiovascular diseases, and was associated with the hypertension risk factors of the metabolic syndrome. However, in this study, the Kimchi intake, even after adjusting sodium intake, did not have negative influence on the development of metabolic syndrome.

This study was designed to examine the level of milk consumption and perception of the school milk programs among elementary, middle and high school students, which provides the information to improve the school milk program. Using a self-administered questionnaire survey, the data collected from 1,725 students nationwide were analyzed. The results showed that whole milk was the type of milk most frequently drunk by the students, although flavored milk and yogurt products were also highly preferred. When asked whether they wanted the school milk program or not, approximately 30% of the students in the schools presently participating in the school milk program and 50% of the students in the schools not participating the school milk program answered "yes". However, all of the respondents preferred to have a choice for the school milk program. The elementary school students showed a higher level of satisfaction with the school milk program than the middle and high school students. Especially, the level of satisfaction with the taste and flavor of the milk was the lowest among the various satisfaction items. However, the students were reported to believe that milk is highly nutritious and good for their health in the present study. Our results suggest that providing a choice of dairy products would improve the students' satisfaction with the school milk program, and that continuous education about the benefits of drinking milk would also encourage them to participate in the school milk program.

The purpose of this study was to evaluate a nutrition education program designed to reduce sugar intake in preschool children. The nutritional knowledge, dietary attitude, dietary behavior, and food intake with a sweet taste in preschool children were tested before and after 4 weeks of nutrition education from March 8 to April 1, 2016. The preschool children were recruited in Dobong-gu, Seoul. The subjects were divided into two groups; educated (N=59) and non-educated group (N=40). Statistical analyseis were performed using SPSS 22. The nutritional knowledge about sweet tasting food was significantly increased (P<0.01) in the educated group and significantly decreased (P<0.01) in the non-educated group. The dietary attitude toward sweet tasting food was significantly decreased (P<0.05) in the educated group but not significantly changed in the non-educated group. The dietary behavior toward sweet tasting food was significantly decreased (P<0.05) in the educated group and significantly decreased (P<0.01) in the non-educated group. The major food sources of sugar intake were not significantly changed in either groups. The major food sources of sugar intake in the 5 years old children were yogurt products>sweetened breads>cookies/biscuits>chocolate>cereals>beverages>sweetened milk>sweet spicy chicken>Tteokbokki. Although there are some limitations in this study, due to the short length of the nutrition education and lack of active participation by the parents, the results suggest that effective nutrition education on sweet tasting food can bring about changes in nutritional knowledge as well as dietary attitude.
Development of Job Description of Nutrition Teacher by the DACUM Method

Journal of the Korean Dietetic Association, volume 22, issue 3, 2016, Pages 193~213

The purpose of this study is to provide a standard job description for a nutrition teacher placed in primary and secondary schools by analyzing their duties. DACUM is an acronym for 'Developing A CUrriculuM'. It was used by experts to determine the job duties, tasks and task elements to establish the job descriptions of a nutrition teachers through the development of a DACUM chart. An expert panel consisting of 10 nutrition teachers participated in a DACUM workshop and derived nutrition teacher's DACUM chart. A total of 1,550 nutrition teachers across the country were targeted as the survey subjects for validation of the DACUM chart through their perception of the frequency, importance, and difficulty of each item in the job description. A tree structure, criticality analysis, and contents validity index were added for verification. The definition of the nutrition teacher's job and DACUM chart with 5 duties, 28 tasks, and 107 task elements were derived by the DACUM method. The definition of a nutrition teacher was 'A teacher who is responsible for food service management and nutrition education and counseling for health promotion and disease prevention for students in primary and secondary schools'. The validation results of the tree structure were the priorities of the 28 tasks with ranks 1 and 2. Because there was no third priority, it was considered to be a good representation of the tasks of nutrition teachers. The DACUM chart was found to be evenly distributed with relative importances of more than 17 or less than 11 through the criticality analysis. Since the C5-4 (Conduct simulation exercise against food poisoning)'s content validity index was significantly less than the reference value of 0.78, it was not included in the final job description. 5 duties, 28 tasks, 102 task elements were included in the final job description of a nutrition teacher.

The purpose of this study was to assess the physical activity of preschool children using an accelerometer and investigate differences related to epoch length setting during use of the accelerometer. Subjects of the study were 26 children (12 boys and 14 girls) at the age of 5, enrolled in one preschool located in Gangneung. From 9:00 a.m. to 4:00 p.m. (7 hours period), every child wore a total of four accelerometers (ActiGraph
, USA), including three attached to the left hip (with epoch length set at 5 seconds, 15 seconds, and 30 seconds). For comparison purposes, a forth was attached to the opposite position, with epoch length set at 5 seconds. Data collected using 15s epoch and 30s epoch (single larger epoch) were compared with those obtained after reintegration of 5s to 15s epoch, 5s to 30s epoch, and 15s to 30s epoch, respectively (smaller epochs reintegrated). According to the results of this study, there were no significant differences in VM between 30s epoch and 5s to 30s epoch reintegrated and in MVPA (moderate-to-vigorous physical activity), between 15s epoch and 5s to 15s epoch reintegrated. From the Bland-Altman plot, reintegration of 15s to 30s epoch in VM and reintegrations of 15s to 30s epoch and 5s to 15s epoch in MVPA can be recommended for assessing physical activity in preschool children. Further research is needed into the reintegration method while using an accelerometer for assessment of energy expenditure in children.

The study suggests the possibility of using internet of things for a dietary intake survey. The development scenario of the dietary intake survey was composed of a weighing sensor for measuring food weight, bluetooth module for communicating through smart-phones, and smart-phone application. The weighing sensor attached to the bottom of utensils was designed to measure the weight of initial food & food eaten, and the results were transmitted to the smart-phone through the bluetooth module. The exclusive application in the smart-phone displayed the results of the amount of food intake, calorie intake, and eating rate. Through this system, subjects could continuously monitor their dietary intake & eating rate and recognize their actual eating environment, which leads to prevent overconsumption of food intake & form balanced eating habits. Based on this system, we need to consolidate and develop a weight control program.
