The purpose of this study was to categorize dietary lifestyles and analyze intake behavior regarding beverages according to lifestyles of 276 university students in Yeungnam region. Frequency analysis, factor analysis, cluster analysis, reliability analysis, one-way analysis of variance, and ${\chi}^2$ tests were conducted using SPSS V.21.0. In the factor analysis, dietary lifestyles were categorized into one of five factors: health-seeking type, popularity-seeking type, safety-seeking type, economy-seeking type and convenience-seeking type. According to cluster analysis, respondents were divided into four groups: convenience-seeking group, wellbeing-seeking group, popularity-seeking group, and indifference group. Chi-square tests showed that there were significant differences in gender, grade, dwelling status, and monthly allowance according to the four dietary lifestyle groups. The level of dietary habits and percentage of correct answers related to beverages of the wellbeing-seeking group were highest among the four groups. The frequency of beverage intake was significantly different for carbonated drinks, milk and dairy products, and sport drinks according to dietary lifestyle groups. In addition, for beverage preference, there were significant differences in carbonated drinks, sport drinks, tea and functional drinks according to dietary lifestyle groups.

Although many studies have focused on dietary habits and behaviors among children, few have looked at individual dietary behaviors and food preferences and their relationships with personality traits. This study examined the relationships between children's dietary behaviors, food preferences and personality traits using a random sample of 236 sixth graders in Chuncheon. Results showed a high prevalence of undesirable dietary behaviors among children: 42.8% of the children had skipped breakfast at least twice a week, 53% had overeaten, 45.8% had eaten irregularly, and 66.5% had eaten an unbalanced meal. These undesirable dietary behaviors were negatively associated with such personality traits as sociability, responsibility, emotional stability, activity, and superiority. When asked about food preference, fruits were most popular while vegetables were least desirable. Total food preference scores were positively correlated with emotional stability (r=.204), activeness (r=.247), sociability (r=.156), responsibility (r=.249), and superiority (r=.133). Preference for meats had negative correlations with responsibility (r=-.133), sociability (r=-.146), and superiority (r=-.132), while preference for vegetables was positively correlated with these personality traits (r=.292, .244, and .230, respectively). In conclusion, the more desirable dietary behaviors and the higher total food preference scores, the more positive the child's personality traits. In addition, preference for vegetables was associated with positive personality traits. The findings suggest the need for continuous attention and guidance on desirable dietary habits for school children both at home and at school.

The Ministry of Agriculture, Food and Rural Affairs has conducted the Dietary Education Projects at Childcare Centers since 2015. This study provides preliminary data for early childhood dietary education programs, by evaluating the outcomes of the projects. This survey enrolled 212 participants whose children had participated in the projects, and 142 non-participants. Comparing the perception of importance towards each educational program of the projects, dietary education program gained significantly higher importance than other subjects included, and was significantly higher in the participants than in non-participants. In the preference for food group survey for children, vegetable and seaweed preferences were higher among participants than non-participants, indicating that participation in the dietary education projects contribute towards increase in preferences for vegetables and seaweed, which children generally dislike. No significant differences were observed in children's dietary habits between participant and non-participant groups, thereby suggesting that the education projects were insufficient for inducing dietary habit changes. In order to accomplish effective improvement of dietary habits, the education projects need further improvements to achieve systematic and long-term plans.

Background: The most beneficial dietary pattern in managing metabolic syndrome (MetS) in the elderly has not been ascertained. The aim of this study is to classify dietary patterns and to examine associations between dietary pattern, MetS and body composition in elderly Koreans. Methods: This study was conducted among Koreans 65 years or older using data from the Korea National Health and Nutrition Examination Survey in 2009. A total of 1,567 study subjects were included. All statistical analyses were conducted using SPSS version 20.0 and dietary patterns were classified by cluster analysis. Results: There were three dietary patterns derived by cluster analysis in this study. We observed that most South Korean elderly still maintain a traditional dietary pattern. Dietary patterns were classified as balanced (31%), imbalanced (40%), or very imbalanced (30%), with the majority of subjects having an unbalanced diet pattern in which their total energy and nutrient intake was insufficient compared with the Dietary Reference Intake for Koreans. Those in the very imbalanced group had a ratio of macronutrients (carbohydrates:fats:protein) of 81.15:7.18:11.50 and a 54% higher likelihood of having hypertriglyceridemia (P=0.025) compared with those in the balanced group. Conclusion: The current findings indicate that the diets of South Korean elderly are nutritionally imbalanced, including high carbohydrate consumption, which confers a high risk hypertriglyceridemia. These findings highlight the effect of nutritional imbalance in elderly with MetS.

This dissertation is a study on the dietary culture of Yuan Dynasty in China and that of Koryo Dynasty in Korea. Yuan Dynasty had some professional books about its dietary culture, and gives us comparetively comprehensive knowledge of the culinary art and foods used in those days. But Koryo Dynasty had few books about its dietary culture. Therefore, we had to collect information found here and there in miscellaneous books belonging to other categories, such as history, literature, medicine, etc. and arrange them in systematic orders. Here are some conclusions of the study.

Purpose: This study investigates the relationship among nutrition knowledge, food habit problems and dietary attitudes in nursing students. Methods: A total of 856 nursing students participated in the study. Data was analyzed by frequencies, t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regressions via SPSS WIN 21.0. Results: The mean scores for nutrition knowledge and dietary attitudes were above average and the score related to food habit problems was high. Dietary attitudes correlated positively with nutrition knowledge, but dietary attitudes correlated negatively with food habit problems. Significant predictors of dietary attitudes included: food habit problems, interest in nutrition and health, exercise, and drinking. The regression model explained 16.4% of perceived dietary attitudes. Conclusion: To improve dietary attitudes among nursing students, nursing educators should develop nutritional educational intervention programs in order to promote nutrition knowledge and identify food habit problems.

Green dietary education emphasized environmental protection and humanity being conducted in middle schools. To develop effective green dietary education program for adolescents, the factors that affected their green dietary practices has been identified. This study aims to identify psychological factors that drive green dietary practices and effect of dietary education that targets middle school students. Data was collected twice from 242 middle school students in Daegu using a self-administered questionnaire in March and June, 2014. There were significant differences in school achievement, economic level and allowance a month (p<0.05) in the green dietary practices and efficacy of students. Three areas (environment, health and traditional, and appreciation & consideration) which were subgroups of green dietary practices were associated with factors such as family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive and negative feelings of happiness (p<0.001). Green dietary practices efficacy was significantly affected by family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive feeling, negative feeling, and negative relationships of happiness (p<0.001). After green dietary education, interests in green dietary, green dietary practices score, the score of health and environment factors of green dietary practices efficacy significantly higher than before education (p<0.05), but all the factors of self-esteem and happiness did not have any significant changes. This study suggests that green dietary education programs for middle school students could account for psychological factors such as self-esteem, happiness according to gender, school records, economic level and allowance a month to be effective.

This study investigated the production of insoluble dietary fiber using forest waste and the dietary effect of manufactured insoluble fiber on physiological function in rat fed high cholesterol duets. Insoluble dietary fiber was prepared from the wood chips of oak (Quercus mongolica). The best condition for steam-explosion treatment for the preparation of insonuble dietary fiber was 25 kg/cm$^3$pressure for 6 minutes. In the chemical analysis of insoluble dietary fiber pretreated by 1% sodium hydroxide solution with steam-exploded wood, $\alpha$-cellulose content was 61.7% in the insoluble dietary fiber which contained 7.6% residual lignin. In order to compare insoluble dietary fiber with commercial $\alpha$-cellulose of physiological function, Sprague-Dawley male rats weighing 100$\pm$10 g were randomly assigned to one normal diet and five high cholesterol diet containing 1% cholesterol. The high cholesterol diet groups were classified as fiber free diet (FF group), 5% commercial $\alpha$-cellulose diet (5C group), 10% commercial $\alpha$-cellulose (l0C group), 5% insoluble dietary fiber dict (5M group), and 10% insoluble dietary fiber (10M group). The rats were fed ad libidum for 4 weeks. Food intake, weights gain, and food efficiency ratio in high cholesterol groups were higher than those of normal group, but there were no significant differences between the experimental groups. There were not any significant differences in the weights of livers, kidneys and small intestine of insoluble dietary fiber supplemented groups, but weight of cecum in all insolube dietary fiber group were significantly higher than those of FF group. A gstrointestinal transit time was decreased by supplementation of insoluble dietary fiber. Weight and water contents of feces in the insoluble dietary fiber supplemented groups were significantly higher than those of the FF group. There were not any significant differences in the activities of the glutamic pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase (GOT) between the experimental groups. In conclusion, the manufactured insoluble dietary fiber and commercial insoluble fiber have the same physiological effects. The preparation method of the insoluble dietary fiber from the oak chips suited its purpose.

Various fractions of apple fibers such as crude pulp, total dietary fiber, soluble dietary fiber, and insoluble dietary fiber were prepared and added to the proteose peptone-yeast extract-fildes (PYF) media to see their effects on the growth of type cultures of intestinal bacteria. Most microbes tested in this experiment grew well in PYF media with the soluble dietary fiber of apple than with the insoluble dietary fiber. Especially Bifidobacterium species such as B. adolescentis, B. animalis, B. infantis, B. longum, B. thermophilum showed higher growth in PYF media containing the soluble dietary fiber than other fiber fractions. However, pectin-added media didn't promote the growth of most microbes used in the experiment. In the in vitro mixed culture using rat feces as starter, the addition of the soluble dietary fiber or pectin to the basal medium showed larger proportion of Bifidobacterium species in total bacteria than that of glucose.
