This study was conducted to investigate the consumption of milk, along with satisfaction for improvement of the school milk program in middle school. The subjects were 447 middle school students(265 male, 182 female) in the Gyeonggi area, whowere asked to fill out the questionnaire. The collected data were analyzed by a SAS package. The results showed that 53.2% of the subjects were participating in the school milk program. Regarding the frequency of milk consumption, 77.7% of students reported daily milk consumption and 65.3% of students reported they drank milk when it was available. 56.8% of the students responded that they were satisfied with the school milk program. Male students not participating in the school milk program cited the reason as "eating at home", while non-participating female students cited the reason as "tasteless". When asked whether they accepted or rejected the school milk program, male students(97.7%) and female students(97.8%) answered "it should be executed". To improve the school milk program, most of the students(72.2%) stated that "it should be selected among flavored milk(strawberry, banana, chocolate, black bean, and husked rice milk) instead of white milk". Therefore, in order to increase the intake of milk, the students should develop the habit of drinking milk to gain the attention of parents. Also, schools should attempt to help through offering proper dietary education.

The purpose of this study was to evaluate the multilateral weight control program provided by the university health care center for female college students. The program was 8weeks long and composed of nutrition consultation, exercise, and behavior modification. Nutrition education focused on a low calorie and balanced diet, increasing the intake of protein and micronutrients and reducing carbohydrate and fat consumption. Evaluations were made upon completion of an 8-week program and upon follow-up at 6 months after the end of program. A total of 92 women completed the 8-week program, while 20 completed the follow-up survey. Upon completion of the 8-week program, significant decreases in body weight, BMI, body fat (kg), and %body fat were observed, and muscle mass was also reduced. The total energy and carbohydrates intake were also significantly decreased in subjects with weight loss, while the percentage of subjects whose consumption of protein, calcium, iron, vitamin $B_1$, $B_6$, and niacin did not meet the EAR, were decreased. The blood values of glucose, total cholesterol and HDL-cholesterol were decreased. The follow-up survey revealed that the subjects continued to lose weight after completion of the program. In addition, a Mini nutrition assessment revealed that diet quality improved, especially with respect to reductions in the consumption frequency of fried, greasy and salty food. In conclusion, the multilateral weight control program with diet education for female college students was effective for long lasting weight control and improved dietary behavior. Nutrition education for weight reduction should focus on balanced nutrition as well as lowering the total caloric intake.

The purpose of this study was to identify dietary factors related to the incidence of diabetes mellitus in Korea. The study consisted of 165 diabetic patients, male and female, aged 30 to 70 years and 198 healthy persons as controls. Diabetic patients who had been diagnosed with diabetes mellitus for less than five years before the study period were recruited from eight different hospitals located in Seoul, Korea. Socioeconomic status, state of illness, physical activity, food habits and food intake were assessed. Food intake was assessed by food frequency questionnaire method using a 105-food frequency questionnaire developed for diabetic patients. The stress and activity indices of diabetic patients were not significantly different from control, but alcohol consumption and smoking levels were higher in diabetics than controls. Other diseases of male diabetic patients included liver diseases, digestive system diseases, and hypertension, while those of female diabetics were hypertension, neuralgia, arthritis and digestive system diseases. These disease patterns are different from Western countries whose most common complications are hypertension and hyperlipidemia. More irregular and less varied meals were found in the diabetic group compared to the control group, suggesting that diabetic patients have generally undesirable food habits. Otherwise, food and nutrient intake of diabetics did not differ greatly from the control group. It was found that diabetic patients consumed more cereals and less fruit than the control group, and also that male diabetics consumed more alcohol. The carbohydrate : protein : fat energy distribution ratio was 61.7 : 15.8 : 22.5 in male patients and 65.1 : 14.9 : 19.7 in female patients. Discriminant analysis showed that diabetes risk factors differed with sex. In male patients, the important factors were body mass index(BMI), vitamin C intake, family diabetic history and vegetable intake, while in female patients they were BMI, cereals intake, carbohydrate intake, vitamin C intake, stress, food habits and Ca intake. These results show that excessive intake of energy and fat are not the major causal factors in Korean NIDDM. Therefore, the diabetes risk factors of Western countries may not directly apply to Koreans. Mors study is needed to clarify the risk factors of Korean NIDDM.

Objective : To examine the association between dietary factors and cognitive impairment in older Korean women living in the community. Methods : Wave 2 data, from the Suwon Longitudinal Aging Study (SLAS), of 365 women aged 65 years or over, were used. The Korean version of the 30-point Mini-Mental State Examination (MMSE-K) was used to assess cognitive impairment (score$\geq$19). Dietary habits and frequencies of food group consumption were also examined. Results : A total of 67 women (18.4%) were found to be cognitively impaired. In bivariate analyses, nondietary factors, such as age, marital status, education, income, self-rated health, depression, emotional support, social activity, exercise, and dietary factors, such as self-rated nutritional status, frequency of beans and bean products and milk and dairy products consumption were associated with cognitive impairment. In the multivariate analysis, a higher frequency ($\geq$1 vs. <1 time/day) of beans and bean products (OR=0.48, 95% CI: 0.23-0.99) and milk and dairy products (OR=0.25, 95% CI: 0.10-0.61) consumption was inversely associated with cognitive impairment, after adjustment for non-dietary factors. Conclusion : These results suggest that dietary factors may play a significant role in cognitive impairment of older Korean women.

This study was carried out in order to facilitate the consumption of milk which tend to decrease in recent years and to improve the school milk program. The survey by means of prepared questionnaire was conducted to investigate a perception and satisfaction of school milk program, and milk intake at home and school with elementary, middle, and high school students. Most of the subjects thought drinking milk is important for their health but only 50.2% of them were actually drinking milk everyday. In particular, the frequency of consuming milk at home was significantly lower in students being provided with school milk program than the students without school milk program. Most of the students commonly drunk plain milk rather than flavored milk, however actually they preferred flavored milk to plain milk. The frequency of consuming milk and the degree of satisfaction for milk being served in the school milk program was lowered. The major reason of disliking milk being served in school milk program was ‘poor taste’. And to promote milk consumption in school milk program, the subjects anticipated the serving of various milk and dairy products, flavored milk and yogurt etc. Thus, it was suggested that to improve the school milk program and promote milk consumption among the students, serving various products that can satisfy their preferences and demands and the proper food guide and education on nutrition are called for.

This study was conducted by empirically analyzing the relation between effects of positive emotional response of female customers, who have at some point consumed food at Korean restaurants in Busan, and behavioral intention according to their food service consumption propensity. In order to achieve the objective of the study, the questionnaire survey was performed from March $10^{th}$ to $25^{th}$, and frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and SEM (structure equation model) were conducted by using SPSS 18.0 and AMOS for 248 questionnaires. As a result of an exploratory factor analysis, five factors were confirmed. In a confirmatory factor analysis, the average variance extracted (AVE) and composite reliability (CR) were confirmed as .508 to .665 and .905 to .946 respectively, which proved the convergent validity. In a hypothesis test, Hypothesis 1 was determined that the food service consumption propensity positively effects on emotional response. The results were as follows: the taste driven (${\beta}$=.325, t=3.907, p<.001), the health driven (${\beta}$=.190, t=2.688, p<.001), and the atmosphere driven (${\beta}$=.188, t=2.515, p<.001). Therefore, Hypothesis 1 was selected. Hypothesis 1 has determined that positive emotional response beneficially affects behavioral intention. As a result of an analysis, the standardized path coefficient was (${\beta}$=.496, t=6.388, p<.001), so Hypothesis 1 was selected. This result suggests that the taste driven factor has the biggest influence on emotional response in the food service consumption propensity for female customers, and food service business operators should strive to make a good restaurant atmosphere for customers to get positive emotional response (pleasure, comfort, satisfaction, and joy).

The main objective of this study was to understand the factors affecting the acceptance of fermented soybean products. Seventy-six consumers rated the acceptance and perceived intensity of 4 types of Korean and 4 types of Japanese style fermented soybean products. The consumer's food variety seeking tendency and the general attitude toward various fermented soybean products were measured. Ten descriptive analysis panelists evaluated the sensory characteristics of the 8 samples. Univariate and multivariate statistical analyses were applied to the data sets. Fermented soybean products consisting of sweet and moist sensory characteristics were preferred the most. The variety seeking tendency was not an effective predictor for understanding the acceptance of the products tasted in the experiment. K-means cluster analysis identified 3 sub-consumer segments sharing a common preference pattern for the 8 samples within each group. These 3 groups somewhat differed in the consumption frequency, acceptance, and familiarity of various fermented soybean products in general.

Food preference of children may be determined by various lifestyle and environmental factors. This study evaluated the effect of rural or urban inhabitance, cooking methods, and frequency of exposure to vegetable dishes on the acceptance of vegetables by 452 fifth grade children. The subjects were students utilizing meal service in public elementary schools in Boryeoung-city, Chungcheong-nam-do (urban); Cheolwon-gun, Gangwondo (rural); or Pocheon-gun, Kyeonggi-do (suburban). A survey was used to determine the preference of students for 59 foods containing vegetables as a primary ingredient, and categorized by fat content (high, low, or intermediate). Children with working mothers and those living in urban areas tended to have less preference for vegetables than their counterparts in rural areas or with mothers who remained at home. Preference for vegetable foods was correlated with the frequency that vegetable foods were prepared by mothers. Vegetable dishes with a high fat content were preferred over those with low or intermediate fat content, except far soup. This study suggests that children who live in urban areas and whose mothers work outside of the home may be predisposed to nutritional deficiencies due to poor acceptance of vegetable foods, and that all children may be at risk for over-consumption of dietary fat, due to a preference for high fat foods.

Purpose: This study investigated an association between dietary quality and use of convenience foods at convenience stores among high school students. Methods: A total of 474 high school students (225 boys and 249 girls) residing in Incheon participated in this questionnaire survey in June 2018. The subjects were divided into three groups according to the frequency of consumption of convenience foods at convenience stores; less than once a week, 1 ~ 2 times a week, and more than 3 times a week. Dietary quality was assessed using a nutrient quotient for adolescents (NA-Q). Logistic regression was used to investigate an association between dietary quality and use of convenience foods at convenience stores among high school students. Results: For boys and girls, higher monthly allowance was significantly associated with the higher frequency of consumption of convenience foods at convenience stores, whereas school grade, mother's occupational status, family size, extracurricular study, and eating speed were not significantly associated with the frequency of consumption of convenience foods. Higher intake frequency of cookies or sweet and greasy bread, processed beverage, Ramyon, night-time snack, and street food was significantly associated with the higher frequency of consumption of convenience foods for boys or girls. Boys and girls, who had a higher frequency of consumption of convenience foods at convenience stores had significantly greater odds for being in the low grade of dietary quality, especially in the moderation factor. Conclusion: The students who used convenience stores more often appeared to have more monthly allowance and to consume undesirable foods more often. Higher frequency of using convenience foods at convenience stores among high school students was associated with lower dietary quality. These study results can support efforts to provide nutrition education programs and guidelines to students who frequently use convenience foods at convenience stores.
