The influence of dietary supplementation with a yeast culture on growth performance, fecal score and nutrient digestibility was evaluated in weaned pigs in a 6-week feeding trial. A total of 50 weaning pigs with an initial average body weight (BW) of $7.46{\pm}1.60kg$ were randomly allotted into 1 of 2 dietary treatments according to the initial BW. There were 5 replicate pens in each treatment with 5 pigs per pen. The dietary treatments were as follows: 1) control, basal diet (CON) and 2) 0.10% yeast culture, basal diet supplemented with 0.1% yeast culture (YC). The average daily feed intake was significantly improved with the dietary supplementation of the yeast culture compared with the control during phases 1 and 3. Overall (0 to 6 weeks), dietary supplementation with the 0.1% yeast culture had a significant effect on the feed conversion ratio (FCR). There was no significant difference in the fecal score between the CON and YC dietary treatments. In addition, no difference in the apparent total tract digestibility was observed between the CON and YC dietary treatments. Collectively, the results of this study indicate that dietary supplementation of 0.1% yeast only improved the feed intake of weaning pigs; however, yeast culture supplementation did not affect the average daily gain, feed efficiency, total tract digestibility of dry matter, and nitrogen and energy levels as well as the fecal scores.

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.

The purpose of this study was to compare dietary culture consciousness of rural and urban housewives through a nationwide survey. Interviewers interviewed 500 housewives(250 in rural and 250 in urban) using closed-ended questions. The dietary culture consciousness was divided into two parts of traditional aspect (dietary habit and ritual diet) and desirable aspect (food choice and nutrition knowledge). Each domain consisted of six items. Results of the study are summarized as fellows : 1) As a whole, dietary culture consciousness of rural housewives was more traditional than that of urban housewives in traditional aspect, and there was no difference of consciousness between rural and urban housewives in desirable aspect. 2) There was significant difference at 1% level between two groups in traditional aspect and there was no difference in desirable aspect. 3) By the analysis of each item, there was significant difference between two groups in 14 items. Especially, the item of westernized breakfast pattern was more acceptable in urban housewives than in rural. 4) In relationship between socio-demographic characteristics of housewives and dietary consciousness of them, age, educational level and religion of housewife were significant in traditional aspect, and so were educational level and job experience of housewives in desirable aspect. Dietary consciousness of rural housewives' was influenced by job experience (in traditional aspect) and age of housewives and level of living (in desirable aspect) In the case of urban housewives, level of living was significant in traditional aspect.

Traditionally, food and medicines are considered as having common roots. That is, their energies share the same source (藥食同源), which has created a unique food culture, and nurtured a unique academic area of dietary medicine (藥膳食料學). This study aimed to develop a desirable dietary life-style based on the oriental dietary medicine theorem originated from the schema of four qi as well as five flavors of foods (四氣五味), originated from the yin-yang and five phase theory based on a clear understanding of a modern point of view, and experimental analysis of nutrients and dietary effects of clear heat effect materials. This study can promote more healthy life-styles and prevent adult diseases by following oriental dietary medicine theory. We should develop a Yack-sun theory and dietary culture that is suitable for physical and genetic health.

Korean culinary culture is traditionally studied through the analysis of foods ingested. However, this study attempts to dialectically reinterpret Korean culinary culture through its relationship to Korean literature. In our study we consider culinary culture prior to the development of scientific techniques and economic growth related to food as "dietary lifestyle of the innocent world" and time since then as "the dietary lifestyle of the experience world". The former represents a simple means of survival without food processing (the "slow food" world), while the latter represents the "fast food" or processed food culture as a modern concept. People living in the age of economic growth and overflowing individualism have lacked an organic life and an opportunity to commune with nature. As a result, they have returned to values of the past, seeking the "slow food" culture to benefit their individual health. A series of return processes, however, were transformed into "the dietary life style of the higher innocence," called "a well-being dietary life style" involving a new healthy conception passing through the dietary life style of the experience world. Therefore, the purpose of this study is to investigate the dietary lifestyles of the "innocent" world and the "experience" world based on dialectic concepts. Individual concepts of "thesis" and "antithesis" are applied, as well as the developmental concept of "synthesis" for the way both symbolic worlds changed to "the dietary lifestyle of the higher innocence" and formed complementary relationships to each other.

A checklist of dietary behavior items for the elderly was developed based on Korean dietary guidelines. First, a literature review was conducted, and 63 preliminary items, including 30 items on food intake, 12 on eating habits, and 21 on dietary culture, were obtained to evaluate the dietary guidelines. The preliminary items were evaluated by experts using Lawshe's method to verify the content validity. They were then revised, resulting in 52 items: 25, 11, and 16 in the food intake, eating habits, and dietary culture domains, respectively. A face-to-face survey was conducted on 331 people over 65 years of age in the metropolitan area, and their one-day food intake was surveyed using a 24-hour recall method in August 2022. The 48 items, including 24, 11, and 13 items on food intake, eating habits, and dietary culture, respectively, correlated significantly with the evaluation indicators of nutrient intake, such as mean adequacy ratio, dietary diversity score, and nutrient intake density. These items were considered suitable for evaluating the elderly's compliance with dietary guidelines.

Effects of a short-period nutrition education program on the dietary behavior and the dietary intake were investigated in sixty nine healthy female college students. Questionnaires for general health information, character type, dietary behavior and dietary intake were answered by the subjects. All the subjects were participated in the nutrition education program which was carried out twice during the study. Subjects were divided into three groups according to their adiposity indices (AI), which are low AI (33 subjects), normal AI (31), and high AI (5). In the normal and the high AI group, the nutrition education program appeared to influence the dietary behaviors of the subjects significantly. However the program did not significantly influence the dietary intake of three groups, except PUFA ratio. It appears that a longer-period nutrition education program is required for influencing both the dietary behavior and the dietary intake of the subjects.

In this study, data was collected on the dietary life education at elementary schools according to the Food Education Support Act using elementary school teachers as subjects. A survey was conducted on 258 elementary school teachers at seven elementary schools located in Seoul, Gyeonggi, and Daegu, Korea from April 14-17, 2010. Most teachers reported that dietary life education was very much needed. The appropriate individuals to teach dietary life education were nutrition teachers, charge teachers, and dietary life education tutors, in that order. The most appropriate time to conduct dietary life education was during dietary life-related subject hours, dietary life education hours, food service hours, and discretionary and extracurricular activities, in that order. The most effective materials and methods used for dietary life education were projection materials and dietary life-related special lectures. Efficient dietary life education methods can be used to develop dietary life education programs. Based on these results, elementary school teachers recognize that dietary life education is very much needed and believe that it would be desirable to conduct dietary life education using nutrition teachers in cooperation with other related teachers.

This study was performed to improve the effectiveness of dietary education using a food ethics approach. Dietary education is a way of practicing food ethics based on Korean culture. The core values of dietary education and the keywords related to food ethics can be combined into environment·life, health·wisdom, and consideration·happiness. Sustainable dietary life comprises the value system of dietary education based on core values. To reach the ultimate goal of food ethics-sustaining the survival of the human race, the coexistence of humans and nature, the coexistence of humans and humans, and the fulfillment of food requirements are needed. These needs yield certain core principles, including respect for life, environmental preservation, justice, the priority of consumers, dynamic equilibrium, and the priority of safety. The extended ethical matrix with six core principles and three interest groups can be used for an ethical analysis either qualitative or quantitative. It is believed that if food ethics are introduced into dietary education programs, the effectiveness of education can be improved.
