Yukwa is a popular Korean traditional fried rice snack. The high fat content and porous structure of Yukwa cause it to rapidly become rancid, presenting difficult challenges for commercial distribution. In this study, an-tioxidant activities of green tea extracts (GTE) were evaluated in Yukwa fried in soybean oil (SBO), rice bran oil (RBO) and winterized rice bran oil (WRBO) during storage at 4$0^{\circ}C$ for 12 weeks. Lipid oxidation of Yukwa was determined by acid value (AV), peroxide value (POV), p-anisidine value(AnV), totox value and sensory evaluation. The addition of GTE to the oils reduced the increases in AV, POV, AnV, and totox. Totox increased most vapidly in Yukwa fried in SBO, fellowed by RBO>WRBO>SBO+200 ppm GTE>RBO+200 ppm GTE > WRBO + 200 ppm GTE (p<0.05). Sensory evaluation revealed that the addition of 200 ppm GTE delays rancidity in Yukwa by 7~8 weeks; providing compelling evidence that GTE is an effective antioxidant for Yukwa.

This research has been surveyed on street food and snack intake status of elementary school students in the Jeon Buk region and the recognition of mothers has been observed for the objective of providing base materials for appropriate eating habits and nutritional education. As for status on intake of street food, most students (97.3%) have shown to have eaten from the street vendors while mothers assume low frequency in their child's intake of street food. Favorite street food choices had an agreement between mother and student as ddukbokki and dakkochi. Students were more tolerant in sanitation and necessity of street food than the mothers. This research shows that there is a difference in the recognition of street food between the students and their mothers. There a need required for improvement in the system as to provide quality food and to prevent poor quality food being exposed to the students. Furthermore, practical and appropriate education must be conducted at home and at school for better choices of food and a better lifestyle.

The objectives of the study were to provide the basis for nutrition education for consumers so that they could select nutritious and balanced fast foods and to promote menu items for fast foods franchisers by addressing nutrition and health. Nine franchisers (3 hamburger, 3 noodles and 3 chicken) were surveyed in terms of their nutritional concern for product development, and 360 consumers were interviewed at 36 fast food chains to assess their perceptions of nutrient adequacy of fast foods. The taste of foods was being addressed most when developing menu items in surveyed franchisers but nutrition and variety of menu were being considered least. Hamburger chain franchisers showed greater nutritional concerns in promoting menu items than noodles or chicken chain restaurants. Their nutritional concerns include utilization of nutritional information as promotion of menu item, providing nutrition information of menu item to consumers, and evaluating nutritional balance of their menu items. As a result of INQ evaluation of combined fast food selected by consumers for a meal, the desirable case of both nutritious and adequate in calorie was 14.7%, nutritious but lack in calorie was 44,1%, adequate in calorie was 24.5%, and undernutritious and lack in calories was 21.6%, 45.7% of snack selected by consumers had more calories than needed for a meal.

본 연구는 초등학교 아동의 식습관, 간식습관 및 섭식실태를 급식교와 비급식교에 따라 비교 분석함으로서 치아우식증 발생과의 관련성을 규명하고, 조사대상 아동들에게 영양교육 프로그램을 실시한 후 교육효과를 평가하고자 실시되었다. 1. 급식여부에 따른 식습관 조사 결과, 급식교 아동이 비급식교의 아동보다 아침식사의 규칙성, 식사속도, 식사량의 적당성 및 식사시간의 규칙성에 있어 바람직한 편이었고, 고기나 생선, 해조류, 우유나 유제품의 섭취정도도 약간 높게 나타나 급식을 통하여 올바른 식생활 태도가 형성되는 것으로 보여졌으며 전반적으로 영양교육 후 식습관에 있어 긍정적인 변화를 나타내 영양교육의 효과가 있었음을 알 수 있었다. 2. 카라멜, 초콜렛 및 사탕류, 비스켓류 등의 치아우식유발 지수가 높은 우식성 식품을 간식으로 자주 섭취하고 있었고 충치유발 요인 인지 시 간식을 덜 사먹겠다는 아동이 급식교에서 다소 많았으며, 물리적 청정작용을 하는 껌을 간식으로 씹는 경우는 1주일에 2∼3회가 가장 높게 나타났다. 또한 영양교육 후 치아우식에 영향을 줄 수 있는 시간인 저녁 식사 후에 간식을 먹는 아동과 TV 광고로 인해 간식을 선택하는 아동의 비율이 낮아졌으며, 세정식품인 채소와 과일, 단백질, 해조류, 우유 또는 유제품의 섭취는 교육 후 약간 증가하였다. 3. 치아우식과 관련이 있는 당질군을 제외한 모든 식품군에서 비급식교 아동보다 급식교 아동의 섭취횟수가 높게 나타났으며 1인 1일 우식성 식품의 평균 섭취 횟수는 평균 5.04회였고, 고체식품보다는 액체식품으로 섭취하는 횟수가 다소 높았다. 치아표면에서 청청작용을 하여 치면세균막의 형성을 감소시켜 우식증을 예방하는 세정식품의 평균 섭취 횟수는 1인 1일 기준식품 표준섭취 횟수보다 높은 9.33회로 나타났다. 1인 1일 우식발생 가능 시간은 100.9분이었는데, 액체 식품의 우식발생 가능 시간은 56.2분으로 44.6분인 고체 식품에서 보다 높게 나타났다. 이상의 결과에서 식습관이 치아우식발생과 밀접한 관계를 가지고 있으므로 초등학교 아동에 있어 치아우식을 유발할 수 있는 간식의 섭취를 줄이되 우식성 식품을 간식으로 섭취한 후에는 잇솔질을 반드시 실시하도록 하며 정규식사에서 치아를 보호하는 세정식품의 섭취에 대한 영양교육이 지속적이고 단계적으로 꾸준히 이루어져야 한다고 본다.

This study was aimed at comparing the dietary patterns of university female students according to their residence type. As for subjects, one hundred and twenty students of Kongju national university were chosen as a total. They were devided into three groups ; those who live in family home, or university dormitory, or self-boarding house. In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day food records and questionnaire. The result was that mean daily intakes of calcium and iron were lower than RDAs in all groups. According to residence type, subjects of family home and self-boarding seemed to have more serious problem in the nutrients mentioned above considering the proportions of less than 2/3 of RDAs. Especially, iron status was poorer than any other nutrients in the aspects of this proportion and food source. Iron was taken largely from vegetable foods which were recognized as a source of low bioavailability of iron. The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 22, 29, 30 and 19. Thus, it proved that breakfast tended to be more negligent than any other meals, and that snack was an important means to give nutrients for subjects. This meal pattern might be one of the factor for the decrease of the dietary quality. Processed foods were founded to be an important source for providing nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients. Percentages of calorie, carbohydrate and fat consumed by processed foods to total nutrients intake were 30.6, 29.5 and 46.2. However, other nutrient intakes from processed foods such as vitamin and mineral were small. And processed foods which give nutrients were mainly cereal products like ra myon, bread, and milk and milk products. Consequently, processed foods seemed to be selected as a combinient substitute food which supply calorie to fill their hunger. According to the living type, dormitory students had them more frequently than any other groups. Food habit score was within the category of poor or fair. Particularly, the score of self-boarding students was the lowest of groups(p<0.05). The major dietary problems were small or overating, missing meal and irregular eating. The degree of these problems was a little different among groups(P<0.01). Nineteen kinds of food were consumed per day, and family home and self-boarding students had foods less variously than dormitory students(P<0.05). Proportions of skipping breakfast, lunch and dinner were 20.8, 12.5 and 8.3%. Accordingly, breakfast was missed more often than any other meals. And self-boarding students missed breakfast more often than any other groups. As a conclusion, subjects should take more calcium and iron, and eat diverse foods to improve their nutritional status. And it is also necessary that breakfast should be regarded more importantly, and that processed foods should be taken considering nutritional balance. In view of residence type, subjects of family home or self-boarding had more dietary problems than dormitory subjects. Thus, these results suggest that university female students might have low ability of meal management, and dietary patterns were different by their residence type. Therefore, nutrition education for them should be carried out with respect to dewelling environment.

Objectives: The aim of the study is to investigate the health belief model affecting the oral health behavior in middle and high school students. Methods: The subjects were 296 middle and high school students in Seoul, Gyeonggi and Incheon from February 15 to March 21, 2014. The students filled out the self-reported questionnaires after receiving informed consents. The instrument was adopted and revised from those of Kim & Hwang, and Choi & Joo. The questionnaire consisted of 4 questions of general characteristics, 9 questions of oral health status including subjective oral health status, frequency of tooth brushing, duration of tooth brushing, method of tooth brushing, use of oral health devices, dental clinic visit, scaling services, snack intake, and smoking. The oral health belief consisted of 25 questions including susceptibility, seriousness, barriers, benefit, and self-efficacy using Likert 5 scale. The reliability of Cronbach's alpha in the study was 0.725. Data were analyzed using SPSS ver 18.0 for frequency analysis, t-test, ANOVA, ${\chi}^2$-test, and Pearson's correlation coefficient, simple regression, and binary logistic regression. Results: Oral health beliefs of middle and high school students affected the oral health behaviors. Susceptibility, barriers and self-efficacy also influenced on the oral health behaviors. In order to provide the best oral health education, susceptibility and self-efficacy are the primary factors to increase motivation because the motivation endows the students with correction of oral health behaviors that improve the knowledge, attitudes, and decrease barriers in oral hygiene. Conclusions: It is important to correct oral health behaviors in the middle and high school students by providing the continuing and systematic oral health education.

This study was conducted to investigate the dietary behavior of day-care center teachers and their meal attitudes during meal time in Jeonju area. Self administered questionnaires were collected from 266 day-care center teachers who worked in a national(public) or private day-care center. The Statistical data analysis was conducted using SPSS v. 12.0. All subjects were women, and 64.7% were married(p<0.001), over more than 60% were junior college graduates(p<0.05), and 73.7% had salaries greater than 1,000,000 won(p<0.001). The breakfast skipping ratio of the subjects was very high, and about 66.5% of the respondents had irregular meals. The snack intake ratios of the subjects in private day-care centers were higher than the subjects in national(public) day-care centers(p<0.001). Approximately 56% of the subjects responded that education about eating is very important for providing balanced nutrition to young children. About 84% of subjects had no experience with the continuing-education program for teachers(p<0.01), and they wanted to know more about balanced nutrition. The meal attitude education score during meal time was $4.53{\pm}0.36$. The relationship between meal attitude education and the dietary behavior of day-care teachers was significantly different based on the "frequency of overeating"(p<0.05) and "self-recognition of eating habit"(p<0.05). These findings suggest that a nutrition education program for day-care center teachers should be developed so that they can effectively manage meal attitude education for young children and provide good nutrition for themselves.

This study investigates the effect of working hours on the dietary behaviors and dietary quality of male industrial workers employed in rotating shifts. The survey was conducted from February to March 2022, enrolling 209 male workers operating in rotational shifts at industries in the Chungcheongnam-do region. Eating behavior and health awareness were investigated during the morning shift, afternoon shift, and night shift for the same subjects. The shift timings were found to be associated with dietary behavior, which had an impact on the dietary quality of workers. Negative effects of shift timings on diet and health were also perceived by the shift workers. The frequency of alcohol consumption was high during the morning shift, and the frequency of night time snack intake was high during the afternoon shift. During the night shift, there was decreased vegetable intake and increased ramyeon intake. Compared to the morning shift, a significant decrease in dietary quality scores was found during the night shift. The workers recognized that rotating shift work negatively affected health, eating habits and sleep. There was a high demand for providing a variety of menus and healthy night snacks in the company cafeteria. When nutritional counseling and educational health services were provided, the willingness to participate was high. Therefore, to improve the health and dietary quality of shift workers, there is a need to provide diets suitable for the working environment and the characteristics, and to provide nutrition management services.

This study aimed to find the differences in weight control status and eating behavior of satisfied and dissatisfied female high school students regarding their own body shape. The participants consisted of 238 students at two female high schools in Nonsan-si, Chungnam-do in May of 2008. Self-assessment evaluated present body shape and ideal body shape they would like to have by providing silhouette drawings. The subjects were divided into two groups, 'satisfied' and 'dissatisfied', according to the differences between present body shape and ideal body shape. In the distribution of subjects according to body mass index, 100% of overweight, 97.0% of normal weight and 48.7% of underweight belonged to the dissatisfied group. There were significant differences in weight control and eating behavior between dissatisfied and satisfied groups in terms of frequency and reasons of conducting weight control behavior, body weight return after weight reduction, skipping breakfast and consuming fast food. The satisfied group was two times more likely to not conduct weight control behaviors compared to the dissatisfied group. The main reason for trying to control weight differed according to the group; the reason was feeling fat in the dissatisfied group and desiring to be healthy in the satisfied group. The percentage of subjects that returned to their original weights after weight reduction was 5 times higher in the dissatisfied group. The percentages of subjects that regularly skip breakfast and consume fast food were both higher in the dissatisfied group than in the satisfied group. The dissatisfied group responded 'eating alone' more frequently among nine binge eating behaviors compared to the satisfied group. Both groups, however, did not show any difference in overeating of meals, eating speed, intake frequency of regular meals, food preference, preferred cooking method, carbonated beverage intake and snack eating behavior. In summary, the dissatisfied group tried more unnecessary body weight reduction and had poor eating behavior. Accordingly, to correct the biased perception of body shape by the majority of female high school students, the values of our society should change toward the pursuit of beauty of health.
