This research was designed and implemented to evaluate how the composition of yaksuncha can affect the health of individuals suffering from diet-related diseases such as obesity and hyperlipidemia by prescribing Yaksun as a nutritional supplement with daily meals. The yaksunucha was prepared as Koekac, Sansa, Heshouwu and Woolong tea and the tea's effects on serum lipids and oxidative stress were evaluated by clinical procedures. The yaksuncha significantly increased HDL-cholesterol and decrease of LDL-cholesterol concentrations in serum. It also had significant effects on decreasing oxidative stress and homocystein levels. The physical characteristics of the yaksunucha were also examined, showing. Brix, pH and titratable acidity values of 1.4, 5.50 and 0.05% respectively. It is thought that scientific and objective evaluations were completed on the components of the yaksuncha prescription. Thus one can concluded that the components could be applied not only in the form of tea, but also various food. The data derived from this study provides basic information that will aid in the application of oriental medicinal resources to other foods as well as facilitate the study of medicinal herbs within the field of functional food research, which already draws sizable attention worldwide.

The purpose of this study was to investigate perception and awareness of yaksun and willingness to eat yaksun in the future, and to examine the factors affecting intake behavior of yaksun of adults in Daegu and Gyeongbuk region. The data were collected in April, 2011 through a self-administered questionnaire. Chi-square test, t test, and binary logistic regression were conducted by SPSS Windows V.19.0. The results were as follows. Almost sixty-six percent of the respondents answered that they knew yaksun. The perception level of yaksun for the intake respondents was higher than that of non-intake respondents. Additionally, many respondents agreed to varied menu development and convenient-food development of yaksun. Intake respondents showed higher level of agreement for the varied menu development of yaksun than non-intake respondents. On the other hand, four fifths of the respondents showed that they would be willing to eat yaksun in the future. The level of willingness to eat yaksun in the future for the intake respondents was higher than that of non-intake respondents. Additionally, the respondents who knew yaksun showed higher level of willingness to eat it than those who did not know it. Finally, the result of binary logistic regression analysis for intake behavior of yaksun showed that gender, educational level, and the awareness of yaksun were significant. On the basis of these results, not only the promotion of yaksun to consumers but also the development of convenient foods, varied menus for different age groups, and menus with cheap prices are needed to raise yaksun popularity.

This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150$\pm$15g, were randomly assigned to groups: basal diet only in normal control group(NCG): basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3mg/ml) injection in heavy metal low duck-juice group(HMLD), basal diet, heavy metals and DJ(30mg/ml) injection in heavy metal middle duck-juice group(HMMD): basal diet, heavy metal and DJ(300mg/ml) injection in heavy metal high duck-juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation in tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.

For the development of Moru wine with enhanced sensory qualities, Moru (Vitis amurensis) wines were fermented with pine needles from Pinus densiflora Siebold et Zuccarini to make Moru-pine wine or medicinal herbs from Astragali Radix and Viscum album to make Moru-herb wine. Moru without pine needles or medicinal herbs was included as a control. Pine needles and Astragali Radix/Viscum album delayed the fermentation of Moru wine, but after 40 days of fermentation and aging, final ethanol contents, pH, acidity, and the sugar/organic acid content in these kinds of Moru wines had no differences. The final ethanol level and acidity of Moru wines were 11.5~12.9% and 1.1~1.2%, respectively, but any sugars (glucose, fructose and sucrose) were not detected in all Moru wines. These results are consistent with the general characteristics of Moru wines, which have a high acidity and low sugar contents. Relatively low browness and antocyanins were detected in Moru-herb wine decreasing its chromaticity in a sensory test. Overall, the supplements of Astragali Radix/Viscum album reduced the color of normal Moru wine, which might be applied toward the development of conventional Moru wines.

Imwonshibyukji is a copying manuscript written around 1825, the 27th year of king Soonjo of the Chosun Period. It is a massive home encyclopedia of total 52 books and 100 volumes. It was quoted from many Chinese literatures The unpublished 'Jeongjoji'of its 17-20th volumes was analyzed to study the cooking methods on the Korean rice cakes (dduck) and studied for the degree of their usefulness and medical values in the light of the cooking and processing science. The book introduced 6 kinds of Korean rice cake: sirudduck (steamed rice cake), chinundduck (steamed and struck rice cake), zizinundduck (small oil fried rice cake), danggui (steamed rice cake mixed with rice power and honey), hondon (=danja: boiled and stuffed rice cake) and butu (fermented rice cake), all of which were composed of total 64 items. The main materials fur the Korean rice cake were as follows: sirudduck and butu were nonwaxy rice powder, chinundduct dinggui and hondon were glutinous rice powder, and zizinundduck was wheat flour. The side material was mainly natural food with the effect of a medicine. The literatures quoted in Imwonshibyukji are as follows: 4 Korean books including Ongheejabji were quoted total 28 times (41.5%), 5 Chinese books including Junsengpaljeon were quoted total 35times (52.2%), and I Japanese book Whawhansamjedohoi was quoted total 4 times (6.0%). The Korean rice cakes quoted in the Korean literature so far exist but the Chinese ones no longer exist. In the comparative analysis of Imwonshibyukji and other contemporary literatures, Chosunmoossangsinsikyorijebub was the most similar one to the book among others.

본 연구에서는 오디 색소인 안토시안을 당으로 안정화시키기 위해 오디시럽으로 제조한 후 오디시럽의 농도를 0%, 5%, 10%, 15% 및 20%로 달리하여 오디시럽양갱을 제조한 후 품질특성과 항산화 활성을 평가하였다. 오디시럽 수준이 높아질수록 오디양갱의 명도(L)값과 황색도(b)값은 감소된 반면 적색도(a)값은 증가하였다. 기계적 물성측정 결과를 보면 경도, 검성 및 씸힘성의 값이 증가하였는데, 이는 오디 pH의 영향으로 생각되며, 관능검사에서도 오디시럽 첨가수준 15%와 20%가 별 차이 없이 좋은 관능평가 점수(맛, 색, 물성 및 전체적인 기호도)가 나온 것과도 관련이 있다고 보여진다. 즉, 오디시럽 수준이 높아질수록 산도의 영향을 받아 식미가 좋아진 것으로 생각 된다. 오디시럽 첨가 양갱의 DPPH 소거능을 $IC_{50}$ 값으로 나타내었을 때 오디시럽 첨가농도가 올라갈수록 $IC_{50}$ 값이 유의적으로 낮아졌는데, 대조군에 비해 MFSY15와 MFSY20의 DPPH 소거능은 각각 17배, 20.1배 증가하였다. 오디시럽 첨가 양갱의 superoxide radical 소거능의 $IC_{50}$값의 경우도 오디시럽 첨가수준이 높아질수록 낮게 나타났다. 따라서 항산화 활성, 관능검사 및 기계적 물성 결과를 함께 고려해 볼 때는 오디시럽이 15%가 첨가된 양갱 시료의 실용화가 바람직할 것으로 판단된다.

As the modern medicine develops, the physique and average life span are increasing. In proportion to that, modern diseases of adult people such as cancer, obesity, arteriosclerosis, cardiac disorder become great social issues. In the meantime, as the development of a new diet brings a new attention, the study is designed to examine the availability of functional food by adding Korean traditional food, soybean Dasik, mulberry leaf. For this study, mulberry leaf was added 0, 5, 10, and $15\%$ respectively to soybean Dasik in proportion to the total weight of soybean power. These are compared with the soybean Dasik itself in relation to the nutritional composition, sensory evaluation, and mechanical characteristics. The results of the research were as follows. Nutritional composition showed that mulberry leaf soybean Dasik increased Na, Ca, K, crude fiber, and ash. As for the result of sensory evaluation of mulberry leaf soybean Dasik, the followings were turned out to be good : color - $10\%$, mulberry leaf smell - $5\%,\;10\%,\;15\%$, bitterness - $5\%,\;10\%$, softness and moistness - $0\%,\;5\%,\;10\%$, and sweetness and overall quality - all the added food group. As the test results of mechanical characteristics, mulberry leaf soybean Dasik showed statistically significant difference only in the hardness, especially high on $5\%,\;10\%,\;and\;15\%$. There were no significant differences in other characteristics. In color, mulberry leaf soybean Dasik showed that L, a and b values decreased as the percentage of addition of mulberry leaf went up. Therefore, the appropriate amount of addition for the production of mulberry leaf soybean Dasik was $5\~10\%$ mulberry leaf in proportion to the weight of soybean power.
