In order to manufacture the alcoholic drinks using cultured wild ginseng roots(CWGR) of 5 and $10\%$ (w/v), sugar content of fermentation media was adjusted to 24-25 $^{\circ}$Brix with white sugar and glucose. And 3 kinds of yeast (S. cerevisiae(KCCM 50757), S. cerevisiae (KCCM 50583) and S. bayanus(ATCC 10601) were used and then the quality of alcoholic drinks was analyzed by physical, chemical and sensory evaluation. Alcohol content was highest value of $15.8\%$ in $10\%$ of CWGR, white sugar, and S. bayanus(ATCC 10601). Major alcohols were ethanol and 1-propanol. Number of yeast cells increased to 5 days fermentation and slightly decreased afterwards. The pH was decreased abruptly from 5.0 in initial fermentation to 3.1-4.1 in 5 days fermentation. Total sugar contents were decreased continuously with fermentation periods and showed 7.0-10.5 $^{\circ}$Brix in 20 days fermentation. Saponin patterns and contents were various and higher in wine treated with S. bayanus(ATCC 10601). From the sensory evaluation, the highest score of overall quality was observed in the alcoholic beverage of $10\%$(w/v) of CWGR, glucose, and S. cerevisiae(KCCM 50583).

Objective: Sweet sorghum is an important forage crop for ruminants, especially in low rainfall areas. Grapeseeds are an abundant by-product of wine-making and contain bioactive substances that can improve the antioxidant capacity of meat. We examined the effect of sweet sorghum forage with supplementary grapeseeds on carcass and meat quality in lambs. Methods: Twenty-eight Small-tailed Han lambs (body weight = 19.1±1.20 kg), aged 3 to 4 months, were penned, and fed individually. The lambs were divided into four groups (n = 7 each) and were offered one of four diets: i) sweet sorghum silage; ii) sweet sorghum silage + grapeseeds; iii) sweet sorghum hay; and iv) sweet sorghum hay + grapeseeds. The grapeseeds were added to the concentrate at 6% DM and the diets were fed for 100 d. Results: Sweet sorghum silage tended (p = 0.068) to increase hot carcass weight, while grapeseeds tended (p = 0.081) to decrease dressing percentage without affecting other carcass parameters. Lambs consuming supplementary grapeseeds increased (p<0.05) meat redness and tended to decrease (p = 0.075) concentration of methionine in meat. Lambs consuming sweet sorghum silage increased (p<0.001) water content of the meat and had a lower (p<0.05) concentration of n-6 polyunsaturated fatty acids (PUFA) and n-6:n-3 PUFA ratio than lambs consuming sweet sorghum hay. Saturated fatty acids content in meat was lowest (p<0.05) in lambs consuming sweet sorghum silage with grapeseeds. Lambs with supplementary grapeseeds tended (p<0.10) to increase eicosapentaenoic acid and docosahexaenoic acid and have a lower thrombogenic index than lambs not consuming grapeseeds. Conclusion: It was concluded that sweet sorghum with supplementary grapeseeds fed to lambs; i) improved the color of the meat to be more appetizing to the consumer; ii) tended to improve the fatty acids composition of the meat; and iii) lowered thrombogenic index of the meat.

Ethyl carbamate (EC) is a contaminant generated in the fermentation processes of various fermented foods. In this study, residue levels of EC in 95 alcoholic beverage samples were determined by using Gas Chromatography/Tandem Mass Spectrometry (GC/MS/MS). All the samples were purified by a liquid-liquid extraction (LLE) method using dichloromethane. The LLE method enables an improvement in time and cost to detection and specificity over the conventional extraction methods. The limits of detection and quantification (LOD and LOQ) to analyze EC were 1.3 and 4.0 ng/mL, respectively. The recovery rates of EC were ranged from 90.0 to 97.5% at the levels of 50, 100, and 500 ug/L. Among traditional grain-based alcoholic beverage samples (n = 34), the average residue levels of EC in takju, yakju, and cheongju were 0.63, 7.01, and 14.11 ug/L, respectively. Among fruit-based alcoholic beverage samples (n = 48), those of EC in japanese apricot spirits, bokbunjaju, grape wines, and other fruit wines were 79.18, 1.66, 2.64, and 2.39 ug/L, respectively. Among distilled or diluted alcoholic beverage samples (n = 13), those of EC in soju (distilled or diluted), general distillates, liquors, and brandies were 0, 3.30, 8.20, and 8.52 ug/L, respectively. Therefore, this study reports that the residue levels of EC in the alcoholic beverages, distributed in the current domestic markets, did not reach its maximum allowed levels of 30 and 400 ug/L established for grape and fruit wines in Canada, respectively.

This study was carried out to develop mulberry wines fermented with traditional microorganisms (Saccharomyces cerevisiae B-8). S. cerevisiae B-8 is a traditional fermentation microorganism isolated from domestically grown Rubus occidentalis. Each S. cerevisiae B-8 and Fermivin was inoculated into mulberry up to $1{\times}10^9$ CFU/kg, followed by incubation at $25^{\circ}C$ for 10 days. Mulberry fermented with S. cerevisiae B-8 (MBB) had a high alcohol content (16.47%), and the fermentation rate of MBB was faster than that of mulberry fermented with Fermivin (MBF). The total polyphenol and flavonoid contents of MBB were higher than those of MBF. DPPH radical scavenging activity of MBB was as high as that of MBF. ABTS radical scavenging activity of MBF was higher than those of MBB and mulberry juice (MBJ). In addition, reducing power of MBB was much higher than other samples. Flavor constituents of the two fermented wines were analyzed by gas chromatography and mass spectrometry. Twenty-three compounds from the sample were separated and identified as fifteen esters, six alcohols, an aldehyde, and an acetate. Particularly, tetradecanoic acid, ethyl ester of orris and violet flavor were ten times more abundant in MBB than in MBF. Several ester components were two times more abundant in MBB than in MBF. In conclusion, current findings indicate that MBB might have better antioxidant activities with flavor, which contributes to improved wine production with high quality and function.

It's not easy to renew old brand of over 50 years history to the tastes of new consumer of our time. Most of national brands that has a history of some 20 years in Korea have strove for continuation and growth of brand to no avails, which can be taken as a good example of current situation. For instance, C company, one of the National brand of US which has a history of 51 years, has made its position secure as a fashion group and based itself on a sound foundation by establishing new marketing strategy and completing successful brand renewal in the process of strategic M&A with Italian company. Those successful marketing strategies are as follows. 1) they regarded both market and consumer oriented marketing activity as company's highest priority strategy and put great emphasis upon concentration on target market and reestablishment of brand image of business casual wear. 2) Setting up and operating planning team composed of merchandizer alone in Milano, they set the direction of plan on the basis of concentrated research on potential item in market according to thorough market research done by buying office in Korea, branch office in Hong Kong and buyer in US prior to blueprint planning for season. 3) Great emphasis was placed on business which focused on intensive presentation of basic key item for apparel career women who are main consumer group in the midium-low prices market in US and on supplementation of size and color. they named this line 'collectibles' and helped their customer develop their own clothes plan without worrying about the change of color and fabric by supporting same fabric and color throughout the year and enabled them to add variation easily by supplementing new trend item. 4) Company set black as a main color that lots of apparel career women find easy to care and to express their own image and presented them with pebble which belongs to navy and beige and added fashion color such as wine and brown etc as season goes by. They constructed basic line in order for their customers to coordinate purchased item with new one or to add them to present collection, and to achieve efficient sale by setting up strategy which allows this cross coordination and changing pattern occasionally. 5) Though basic jacket for 99$, short slim skirt for 49$ are products within midium-low prices range, in the material planning stage aiming at production of item that has both resonable function appealing to consumer and is fashionable, synthetic material had to be used as a main source due to price competitiveness. Despite this situation, considering comfortable sense of fit and refined drape of silhouette that has no sign of cheap material, whole collectible line was divided into two items, which contributed to reduction of cost. In case of material that is composed of triacetate and polyester in 70 to 30 ratio, was used up to 4 million yard, which allowed drastic curtailment of cost accompanied by concentration. In case of 'collectibles' line, using Korean material mainly, C company chose to have their product sewed in Southeast Asian countries where transportation is well developed and both productivity and quality verified by operating global production system which aiming at cutdown of cost through outsourcing production from the country where labor cost is low and getting finished product. Polarization between present consumers telling us that consumers with the mind of middle classes in the past no longer exists between consumers who seek after only fine article of highest quality and wise consumers who are sensible enough to judge bubble on correlation between price and quality. To cope with this change in new consumer mind, apparel makes changing their policy so as to produce item that has reasonable quality and falls within affordable price range anywhere in the world. and they're striving to get out of difficult situation by operating global marketing strategy which stresses separation of planning, production and sale and sensibility of fashion shared worldwide. The marketing strategy of C company can be exemplified as a successful one.

Kidney bean was used in the brewing of Takju. The Takju formed varied the percentage of kidney bean used; that is, 0%(only rice) in $T_{-1}$, 100%(only kidney bean) in $T_{-2}$, 90% in $T_{-3}$, 80% in $T_{-4}$, 70% in $T_{-5}$, 60% in $T_{-6}$, and 50% in $T_{-7}$. We determined the total sugar, pH, reducing sugar, alcohol production, acidity, and DPPH free radical scavenging activity of Takju. The acidic value of $T_{-1}$ was above that of $T_{-6}$, and the pH of $T_{-2}$ was above that of $T_{-1}$. Both satisfy the food code parameters (namely, below 0.5 in acidity, 3.8~4.7 in pH). The alcohol production of $T_{-1}$ was above that of $T_{-2}$. For 2 days of fermentation, the reducing sugar of $T_{-1}$ totaled 2, down from 4.96%. After fermentation, there was not much difference from 4 to 12 days. The antioxidative effect of $T_{-1}$ proved to be much better than those of the other. Thus, we can be seen that these results thus indicate that the role of kidney bean added to Takju show good antioxidative activity. From the result of sensory test, we also concluded that the taste of Takju kidney bean is very similar to that of Takju with rice.

The physicochemical characteristics and sensory properties of Jinyangju were investigated at different degrees of milling (DOM; 0, 5, 7, and 10%) of waxy glutinous rice after 2 weeks of fermentation. The final pH values were 3.50, 3.84, 4.16, and 4.21 at the DOMs of 0, 5, 7, and 10%, respectively. The final total acidities were 1.21, 1.16, 0.94, and 0.91%; final total sugar contents were 6.38, 6.51, 5.54 and 5.40%; and final alcohol contents were 14.50, 14.50, 15.50, and 15.40%, respectively. Hunter L-value of the DOM 5% rice was lower those of the DOM 7% and 10% rice, but its Hunter b-value was higher than those of the DOM 7% and 10% rice. However, Hunter a-value of the Jinyangju were not significantly different among the samples (p>0.05) Hunter L-value. The Jinyangju made with the DOM 7% rice showed the highest overall sensory preference.

At present in many cases the methods of medical treatment in Oriental medicine Korea lays emphasis on internal use, but to improve the curative value and for the diversity of medical treatment it is desperately needed to study external medical treatment more deeply. From the viewpoint of medical science history, as various additives and new discoveries are developed this has made it easy to use and improved the curative value of it ; thus external medical treatment has been rapidly progressed both in quality and quantity. Therefore, in studying the external medical treatment, it is very important to know it's history. So, I intend to study the early external medical treatment first. The external medical treatments mentioned in the Mawangtew medical books (52Byeongbang, Yangsangbang, Japryobang, Taesanseo), Hwangjenaekyeong, and Geumgweyoryak which were written or presumed to be written in early times were examined to study the early external medical treatments. The parts of body or diseases in which external medical treatments were applied; the methods of external application and the administration of medicine; the number of prescriptions, and the herbs used are also examined. I came to the following conclusions as I compared the kinds of books with the itemized lists based on the results of examination. 1) Though Mawangtew medical books (52Byeongbang, Yangsangbang, Japryobang, Taesanseo) was written earlier than Hwangjenaekyeong and Geumgweyoryak, there are more incidents of the disease in which external medical treatments were applied, the methods of external application and the administration of medicine, the kinds of prescriptions , and the different herbs used in Mawangtew medical books than in Hwangjellaekyeong and Geumgweyoryak. 2) In the six medical books mentioned above there are more prescriptions for external diseases and dermatitis than for internal diseases. 3) From the viewpoint of the number of prescriptions, the most frequent use of a medicine type was a natural type of medicine. The second was ointment type, and the third was liquid type. A powder type was the fourth. 4) In the administration of medicine, combination types such as both pasting and plastering were used most frequently. 5) Vegetable, mineral and animal nature herbs were used diversely for the early external medical treatments. Things such as wine and vinegar were also used as a herb.

This study was performed to investigate the effects of pre-soaking methods on the preparation of Rehmannia radix Preparata (R.P). The R. radix L (R.L) was soaked in distilled water and traditional Korean wine for 24 hr, then the soaked R.L was treated with a traditional nine-time steaming process. Next, catalpol, 5-hydroxymethyl-2-furaldehyde (5-HMF), polyphenols, flavonoids, antioxidant activities, and ACE inhibition activity were analyzed for the R.P produced by the different methods. The catalpol content of the R.L was 631.4 ppm, but the content decreased as steaming increased to 8-9 times. The 5-HMF, polyphenol, and flavonoid contents of the R.L were 0.12 mg/g, 5.09 mg/g, and 0.83 mg/g, respectively, and these increased gradually with increasing steaming times. As the steaming times of the distilled soaking water increased, the antioxidant activities of 1 mg/mL increased from 19.44% to 75.60% at 14 times of steaming. The ACE inhibition activities of 1 mg/mL of the distilled soaking water increased from 28.70% to 94.78% at 10 times of steaming, but decreased afterward.

;Jindo Hongju is an unique red-colored traditional distilled wine of Korea. The unique attractive color of Jindo Hongju is due to the pigments of gromwell (Lithospermum erythrorhizon) root, derivatives of naphtoquinone such as shikonin and acetylshikonin. Which are extracted during the distillation process. The attractive color of the gromwell pigments is easily changed to dark red or to brown causing deterioration of the Quality of Jindo Hongju. Due to the discoloration of the pigments and to the limited supply of gromwell roots, some brewers manufacture spurious Jindo Hongju using artificial colorants. This study was performed to devise a simple method of detecting spurious Jindo Hongju products. The color of the gromwell pigments was greatly affected by pH change and the change could be demonstrated by the change of the absorption spectrum. At pH 4.0 the normal pH of Jindo Hongju, the absorption spectra of gromwell pigments and genuine Hongju products showed an absorption maximum of 520 nm. The absorption maximum was shifted to 570 nm and to 616 nm as the pH was raised to 7.0 and 11.0 respectively. This transition due to the pH change was also demonstrated on em chromaticity diagram. The characteristic transition due to pH change of gromwell pigment solution was not observed with an artificial colorant (red No.2) which was suspected to be used in the manufacture of imitation products. The absorption spectra of most of the Jindo Hongju collected from the market were similar to that of the gromwell pigments and showed the characteristic transition due to pH change with the addition of NaOH. However, with a few of the products, the absorption spectra was similar to that of the artificial colorant and the characteristic transition due to pH change was not observed, indicating these products might have been forged. The result of study suggests that the transition of the absorption spectrum and the change of the color due to pH change be used for the detection of imitation products. Farther more, since, at pH above 9.0, the color of the gromwell pigments and genuine Jindo Hongju could be visually differentiated from that of the artificial colorant and forged products, it might be possible that the forged products be easily detected by raising the pH to above 9.0 and visually comparing the color with that of the gromwell pigment at the same pH.me pH.
