Abstract
The aim of this study was to assess University students` consumption pattern of Korean rice cakes and to analyze the preference of Korean rice cakes by their demographic backgrounds. The results of this study will be useful information for systematic development and wide distribution of Korean rice cake as a traditional Korean food. A self completed survey of 392 University students in Seoul was undertaken and detailed information was collected. The survey questionnaire consisted of three parts including demographic backgrounds, student`s consumption pattern and preference of Korean rice cakes by type. Approximately half of the students were male (52.6%) with the average age of 21.1 years old. Most of the respondents (92.3%) were from nuclear families. The consumption frequency rate showed that 38.8% students had Korean rice cake once or twice a month followed by once a week (29.8%), once per six months (21.7%), and once per two months (8.2%). Ingeolmi received the highest preference score (4.15), whereas Duteopteok had the lowest score (0.18). The correlation coefficient for paired samples between students` preference of Korean rice cake and their knowledge of them was 0.827, showing statistically strong positive correlation between them.

Abstract
The rheological properties of dough made from composite flour containing 30% of buckwheat flour with 80% of extraction rate and 70% of wheat flour, with addition of vital wheat gluten and/or gums, were studied for the development of buckwheat bread. From the farinograph data, water absorption, development time, and stability of the dough decreased as the amount of buckwheat flour increased. However, the addition of gluten increased the water absorption and development time but decreased the weakness of the dough. The use of xanthan gum showed a stability-increasing effect. From the extensograph data, extension and strength of the dough decreased with increasing amount of buckwheat flour, but resistance to extension increased. The addition of gluten increased the extension and strength of the dough, but decreased the resistance to extension. Guar and xanthan gum added at 0.2% level had little effect on extensograph data of the dough. Overall, addition of, vital wheat gluten improved the properties of buckwheat bread dough better than water-soluble gums.

Abstract
This study was to investigate the knowledge of Korean festival foods and the acculturation of American main traditional occasions among Korean American housewives residing in the New York and New Jersey area. Out of 400 questionnaires, the 271 respondents were taken. Of the respondents, 77.1% demonstrated the interest in Korean festival foods. The most important Korean festivals were Chusuk (52.0%), Sulnal(46.9%) and Daeborum (1.1%). In order to make the Korean festival foods to be international foods, the most vital factor was taste and flavor (39.5%), cooking method (34.7%), preservation (10.3%), sanitation (8.1%) and nutrition (7.4%). American Thanskgiving Day was the most important occasion among the Korean American housewives. The factors that keep the American traditional occasions were related to whether the respondents had an occupation or the length of stay in the U.S.A. But in case of Korean festival foods, the factors cannot be applied. On the contrary, they do still keep the tradition and the interest of Korean festival foods in U.S.A. As a result of that, the Korean festival foods in the U.S.A. are systemized for the preservation and popularization for the coming Korean generation.

Abstract
The breadmaking characteristics of composite flour containing 30% of buckwheat and 70% of wheat with the addition of vital wheat gluten and water-soluble gums, were studied to establish the optimum formula for the development of buckwheat bread. The addition of vital wheat gluten or/and gums led to successful formation of buckwheat bread, giving loaf volume increase and improvement of sensory quality, especially texture determined by QDA (Quantitative Descriptive Analysis). Among those additives, xanthan gum showed the best volume expansion. Synergistic effects on bread quality were observed when the vital wheat gluten and xanthan gum or guar gum were used together. As buckwheat flour was substituted for wheat flour, gelatinization started early and the maximum viscosity increased measured by an amylography. The addition of gluten and gums caused the initial gelatinization to occur at a higher temperature and maximum viscosity to decrease.

Abstract
The changes in weight, reducing sugar content, sugar composition and enzyme activities (β-amylase and invertase) of sweet potato were studied with three kinds of cooking methods, microwave oven, gas oven, and steaming. The weights of sweet potato cooked by microwave oven and gas oven were decreased with increasing cooking time, whereas that of steaming was increased with cooking time. Reducing sugar content of sweet potato cooked by microwave oven was increased till 40 seconds, but decreased thereafter. In the cooking methods using gas oven and steaming, reducing sugar content were increased with cooking time. And reducing sugar content were 334.60 ㎎/g and 381.29 ㎎/g, respectively at 100℃ of cold point in sweet potato cooked by gas oven and steaming. Raw sweet potato consisted of fructose (1.56 ㎎/g), glucose (1.79 ㎎/g), sucrose (5.58 ㎎/g), and maltose (2.22 ㎎/g). The contents of fructose, glucose, and sucrose were decreased during cooking process. But maltose content was increased with cooking time. Especially, maltose contents were 24.81 ㎎/g and 28.10 ㎎/g at 100℃ of cold point in sweet potato cooked by gas oven and steaming. The activities of β-amylase and invertase were decreased with cooking time. Microwave oven-cooked sweet potato did not show on invertase activity.
