In order to standardize a recipe of Jeung-Pyun, fermented rice cake, we studied the sensory, rheological and physicochemical characteristics of Jeung-Pyun in terms of fermentation time and ratio of ingredients. Jeung-Pyun fermented for 3 hours was higher in pH, better in taste, hardness and overall quality than that fermented for 7 hours. It was softer, and had more moisture and fine grain as the amount of added water increased. Jeung-Pyun made with 80% added water had the greatest volume. Jeung-Pyun without salt was the worst in color and flavor and the smallest in volume. As the Jeung-Pyun was added more sugar and Tak-Ju, the volume was more larger and the moisture was more less. Taste and overall quality of Jeurig-Pyun was not affected by the amount of Tak-Ju added. The pH of Jeung-Pyun was lower as it was added more Tak-Ju. Therefore, Jeung-Pyun which is fermented for 3 hours, with 70% water, 0.8% salt, 15% sugar, and 30% Tak-ju was the most acceptable one in terms of sensory qualities and physiochemical properties.

The purpose of this study is to offer youth with the basic materials for developing nutrition education programs and to help domestic science teachers in schools implement effective dietary education by examining their awareness of food additives. In the source of acquiring knowledges on food additives, the results were through mass media, technology and home economics teachers, and family members in order. The majority of students thought that they don't need the education about food additives. As effective teaching methods, they first selected the use of visual media, followed by experimental cooking classes, field trip, and inquiry lessons using processed foods. As a result of analyzing the education on food additives in accordance with demographic factors, more number of female students, compared to male students depicted the need for education on food additives. Further, the lower the cost students spend on purchasing processed foods per day, the higher the necessity of the education they indicate. The necessity of education content on food additives showed significant difference depending on the cost of buying processed foods, and the degree of interest and help real-life according to gender indicated significant differences. The satisfaction with education on food additives, which was implemented in home economics education revealed significant differences according to gender. This study aims to provide the basic data for the development and research of educational programs regarding good eating habits among the general youth. However, there are limitations to the presentation of the practical training program. For this reason, based on the results of this study, further studies should follow this study in order to develop and study educational programs related to food additives for teaching and learning purposes.

The purpose of this research is to develop a Home Economics education curriculum that can promote citizenship through critical literacy. To this end, the 'housing' area in the 2015 revised curriculum of home economics and textbooks were analyzed from a critical literacy perspective. Using Laster(1986)'s critical science curriculum development course and "A Teacher's guideFamily, Food and Society"(Staaland & Storm, 1996), a 'Citizenship raising curriculum of home economics education in the housing area.' was developed. The results of this research are as follows. First, when the the curriculum was examined, the teaching objectives of the overall subject, or the achievement criteria, learning elements, and evluative methods of the housing area consisted of practical problem solving curriculum that can include critical literacy content. In addition, as a result of analyzing the text of the three textbooks' housing areas, it was found that most of them were described as adapting to and coping with the current culture, and few problems or social issues were mentioned that could lead to critical literacy. Second, the housing area curriculum for critical literacy learning was developed, with a total of 13 plan of 7 modules including continuous interests, valued ends, learning contents, and 26 learning materials including reading materials, and video materials. Based on the findings, the next curriculum and textbook should address social issues related to critical literacy and various classes of housing, and teachers' communities and training should be operated to support teachers who can be examplary for practical reasoning and critical thinking.
