The purpose of this study was to develop a dietary life education program for adolescents and evaluate its effectiveness. The program was divided into three areas: 'Natam' (taste education), 'Wetam' (traditional dietary life education), and 'Gitam' (sustainable dietary life education), consisting of a total of 10 units primarily focused on cooking activities. For participants aged 14~17 years, face-to-face pilot education was conducted by a trained instructor once a week for 10 weeks. A questionnaire survey was performed to evaluate the educational effect(n=72) and satisfaction(n=82) during education period. Significant improvements were observed in knowledge levels for the 'traditional dietary life education', and 'sustainable dietary life education' which were identified as insufficient in the preliminary survey. Attitude and behavior levels were significantly improved across all areas. Satisfaction was high with a score of 4 out of 5 points for all areas. In conclusion, this program was found to be effective, and further emphasis should be placed on traditional and sustainable dietary life education to enhance its impact.

To determine the effect of dietary potassium and lysine levels on blood parameters, serum and bone composition, 360 male broiler chicks of 3 days of age were used in a completely randomized $3{\times}3$ factorial experiment for 6 weeks. Experimental diets contained three supplemented levels of dietary potassium (0.3, 0.6 and 1.2%) and three supplemented levels of dietary lysine (0.6, 1.2 and 2.4%). Dietary levels of potassium and lysine did not influence blood pH, $pCO_2$, $pO_2$, $HCO_3$ and total $CO_2$ and interaction between potassium and lysine was not shown (p > 0.05). Serum lysine and arginine contents were significantly different by the levels of dietary lysine (p < 0.05). Lysine-arginine antagonism was observed in high lysine diet. But increasing dietary potassium did not alleviated the lysine-arginine antagonism. Serum sodium, potassium and chloride were not affected by dietary potassium and lysine levels (p > 0.05). Femur weight, length and P contents were affected by the levels of dietary lysine (p < 0.01). But no difference was observed in femur ash and Ca contents (p > 0.05). Interaction between potassium and lysine was shown in ash and P contents (p < 0.01).

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.

Objectives: The purpose of the study was to examine dietary life characteristics such as knowledge, self-efficacy and dietary behavior of preschoolers in Namyangju, Kyunggi-province, Korea. Methods: The survey questionnaire was developed based on literature review. Preschoolers aged 4-5 years (n=208) responded to the questionnaire to measure knowledge, self-efficacy, food preference, and dietary behavior. After excluding incomplete responses, the data of 197 subjects were used for analysis. Results: Mean score of dietary life knowledge was 8.0 out of 12, showing a low level of knowledge. Two out of 12 knowledge items were significantly different by gender. Percentage of correct answer on items of 'foods to make bones strong' and 'kinds of fast foods' was higher in girls than in boys (p<0.05). Total score of self-efficacy regarding dietary life was 40.1 (possible score: 12~48), on average. Compared to girls, boys had more confidence in 'not over-eating', and 'eating balanced meals with meat, fish and vegetables' (p<0.05). Boys scored higher on total score of food preference than girls (p<0.01). The preference for fruits was quite high. Among food items, boys scored higher on the preference for rice (p<0.01), fish (p<0.01), pork (p<0.05), beef (p<0.05), milk (p<0.01), and ice cream (p<0.05) than girls. Boys also liked fast foods more than girls did, showing preference for chicken (p<0.01) and soda (p<0.05). Compared to girls, boys showed more desirable behavior in 'eating breakfast everyday' (p<0.01). Dietary behavior was significantly correlated with self-efficacy (r=0.52, p<0.01), food preference (r=0.35, p<0.01), and knowledge (r=0.25, p<0.01) of subjects. Conclusions: In this study, we observed differences in food preference by gender. Dietary behavior of preschoolers was correlated with several factors, including dietary life related knowledge, self-efficacy and food preference. Thus, it is needed to develop nutrition education programs focusing on increasing dietary life related knowledge and self-efficacy, and consider the differences in food preference of preschoolers by gender.
