This study was conducted to investigate the actual conditions of intake of Korean traditional beverages in 273 female university students in Seoul, Korea. The subjects of this study consisted of 128 food and nutrition majors and 145 non-majors. Questionnaires were administered to the subjects who had an average age of 20 years. Two-hundred and nineteen students (80.2%) lived with their parents. Regarding the type of beverages subjects often drink, coffee was the most preferred (51.3%) overall, and non-majors (4.1%) were shown to drink traditional beverages more often. Regarding preference for traditional beverages, most subjects (72.5%) responded that they liked their own traditional beverage. However, for frequency of intake of traditional beverages, 48.7% answered they do not drink any traditional beverages. The reasons why subjects like traditional beverages were taste (71.7%) and health (26.3%), and the type of traditional beverages they often drink were Yulmu tea (35.9%), Sik hae (30.8%), and Yuja tea (10.6%), in order. Regardless of major, ginseng tea, jujube tea, mulberry-leaf tea, Chinese matrimony vine tea, ssanghwa tea, ginger tea, and omija tea were found to be satisfactory traditional beverages. Therefore, due to the low intake frequency, preference, and satisfaction of traditional beverages, new traditional beverages that can meet the standards of female students should be immediately developed.

In terms of awareness of Korean traditional food, elementary students are most affected by their parents. The objective of this study was to analyze upper grade elementary students' parental awareness and preference of Korean traditional foods in the Chungnam Area. In a survey of 126 parents, 58% of subjects were interested in Korean traditional foods, but there was no significant difference according to age. About 87% of parents thought that inheritance of knowledge on Korean traditional foods was needed. The reasons for inheritance of knowledge on Korean traditional foods were 'To stick to style of Korean traditional foods' (68.2%), 'Palatable' (21.8%), 'Education for children' (6.4%), and 'Beautiful and fine custom' (3.6%). The awareness point of 'Korean traditional foods are easy for cooking' increased with increasing age (p<0.01). In all age groups, subjects highly recognized that Korean traditional foods are good for health. There were significant correlations between overall preferences for Tteok and Hankwa (r=0.351, p=0.001), Hankwa and Korean traditional drink (r=0.374, p=0.001), and Korean traditional drink and Tteok (r=0.406, p=0.001). As a result, preferences for other items also increased when preference for one of the three traditional foods increased. Therefore, education on Korean traditional foods is necessary in order to satisfy parental preferences.

The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

A Korean commercial sweet rice drink "Sikhye" showed sucrose, fructose, glucose, maltose, limit dextrin and various size of maltooligosaccharides in HPLC and TLC analysis. Commercial Sikhye was found to contain 0.09% of limit dextrin and 0.2% of rice residue. Limit dextrin in commercial Sikhye showed both signal of $\alpha$-1,4- and $\alpha$-1,6-glucosidic linkage with its estimation ratio of 15:1 by 1H-NMR analysis. This limit dextrin was hydrolyzed to produce various size of maltooligosaccarides with more longer chain than that of traditional Sikhye by pullulanase. Limit dextrin was digested wit enzymes(30units/ml) of $\alpha$-amylase, $\alpha$-glucosidase and glucoamylase from Aspergillus awamori, sweet potato $\beta$-amylase and human salivary $\alpha$-amylase at 37$^{\circ}C$ for 1 hour, respectively. Hydrolysis rates of these amylases on it were higher than in case of traditional sikhye. $\alpha$-Glucosidase plus human salivary $\alpha$-amylase hydrolyzed it to 61.3%. Hydrolysis rates of these amylases on rice residue were lower than that of traditional Sikye. These results suggest that limit dextrin in commercial Sikhye is less effective than isomaltooligosaccharides in traditional Sikhye as a growth factor for Bifidobacterium while rice residue in commercial Sikhye is more effective than that in traditional Sikhye as dietary fiber.ary fiber.

In Korean Traditional Medicine(K.T.M.)'s theory, there are some important constitutions which constitute the human being. They are Jeong(精), Gi(氣), Sin(神), and Hyeol(血). Jeong(精) is the essential substances which constituting human body and maintaining life's activities. Gi(氣) is the vital energyor functional activities of human body. Sin(神) is a kind of Gi(氣) which is related to mentality, consciousness and thinking. Hyeol(血) is the red fluid circulating through the blood vessels and nourishing the body tissues. When a man is born, he takes Jeong(精) from his father, and Hyeol(血) from his mother. So father' s Jeong(精) and mother' s Hyeol(血) became the source of their children's Jeong(精), Gi(氣), Sin(神), Hyeol(血). But after be borning, man need to make Jeong(精), Gi(氣), Sin(神), Hyeol(血) by himself from Foods and drinks[水穀]. This thesis was written to explain a process or a system how the Foods and drinks[水穀] change to human's Jeong(精), Gi( 氣), Sin(神), Hyeol(血). When the food and drink[水穀] put in human's mouth, Five Bu[五腑] primarily digest and change to food and drink[水穀]'s Essence and nutrients which is similar to chyme or chyle[乳廳]. Secondarily, Five Jang[五臟] make Gi(氣), Jinaek(津液) - the body fluid, Jeong(精), Wigi(衛氣) - the defensive Gi, and Yeonggi(營氣) - the nutrient Gi circulating the Meridians, and Hyeol(血) from that food and drink [水穀]'s Essence and nutrients. And the information of every processing is reflected in urine. 50 the digestion is accomplished at not only Five Bu[五腑] but also five Jang[五臟]. The concept of digestion in this thesis is including both catabolim[異化作用] and anabolism [同化作用]. Samcho(三焦) is the recognition to the process of this digestion - ctabolism and anabolism in three part.

A survey was carried out regarding university students' recognition of high-caffeine energy drinks in an effort to identify and improve problems as well as provide basic data. Most of the subjects had previous experience of energy drink consumption. Studies showed that most students consumed energy drinks when studying. Regarding frequency of energy drink consumption, most students' responded "1~6 times a year"; female students showed lower frequency of energy drink consumption than male students. Both male and female students used convenience stores to purchase energy drinks. In most cases, students became aware of energy drinks through advertisements on TV, radio, newspapers, and magazines. The most important factor affecting their energy drink purchase and consumption status was taste. The most frequent adverse effect they experienced after drinking an energy drink was unusual heart-pounding, whereas the biggest problem caused by energy drink consumption was addiction. This study indicates that students should have a better understanding of the problems associated with excessive and prolonged high-caffeine intake. In addition, instructions for proper purchasing and consumption of high-caffeine energy drinks should be provided as well as education and campaigns concerning symptoms caused by high-caffeine energy drink consumption so that students may refrain from excessive consumption. Further, civil organizations and the government need to devise effective measures for proper regulation of high-caffeine energy drink consumption.
