Kimchi is a representative traditional food in Korea and a type of vegetable product that is the unique complex lactic acid fermentation in the world. It can be considered as a unique fermented food generated by various flavors, which are not included in raw materials, that can be generated by mixing and fermenting various spices and seasonings, such as red pepper powder, garlic, ginger, and salted fish, added to Chinese cabbages. Functionalities in Kimchi have been approved through several studies and the probiotic function that is mainly based on lactic acid bacteria including their physical functions in its contents has also verified. Studies on the verification of the safety of Kimchi including its physiological functions have been conducted. In particular, the function of lactic acid bacteria, which is a caused of the fermentation of Kimchi. Although the lactic acid bacteria contributed to the fermentation of Kimchi is generated from raw and sub-materials, the lactic acid bacteria attached on Chinese cabbages has a major role in the process in which the fermentation temperature and dominant bacteria are also related to the process. The salt used in a salt pickling process inhibits the growth of the putrefactive and food poisoning bacteria included in the fermentation process of Kimchi and of other bacteria except for such lactic acid bacteria due to the lactic acid and several antimicrobial substances generated in the fermentation process, such as bacteriocin and hydrogen peroxide. In addition, the carbon dioxide gas caused by heterolactic acid bacteria contributes to the inhibition of aerobic bacteria. Furthermore, special ingredients included in sub-materials, such as garlic, ginger, and red pepper powder, contribute to the inhibition of putrefactive and food poisoning bacteria. The induction of the change in the intestinal bacteria as taking Kimchi have already verified. In conclusion, Kimchi has been approved as a safety food due to the fact that the inhibition of food poisoning bacteria occurs in the fermentation process of Kimchi and the extinction of such bacteria.

This study covers the historical aspects of the turmeric and curcuma only in detail on the medicinal uses, supported by references to the medical texts. And the result is as follows: 1. Turmeric and curcuma are rhizomatous herbaceous perennial plants of the ginger family, but both produced on the same herb. The rhizome is considered turmeric while the tuber is considered curcuma. 2. Turmeric is the round, oval, or ovate, and scutiform rhizome. 3. Curcuma is yellowish externally, internally more or less orange-yellow passing into reddish-brown. The tuber has a round and cuspidate appearance. The smell is aromatic, somewhat analogous to ginger. 4. Turmeric is somewhat analogous to curcuma in shape, but turmeric is pungent and bitter in taste, warm and intoxious in property, and yellow in color, acting on the spleen and liver channels and governing the gi of the blood while curcuma is pungent and bitter in taste, cold and intoxious in property, red in color, acting on the heart and pericardium channels and governing the blood. 5. Turmeric is referred to zedoary, sliced turmeric, old jaundice, precious aromatic, and ovate rhizoma, and curcuma is referred to radix curcuma, curcuma aromatica, and cicada-belly curcuma

The aim of this study is to examine the influences of spices on the amounts and compositions of volatile compounds released from cooked beef patty. Beef patty with 0.5% of spice (nutmeg, onion, garlic, or ginger powder, w/w) was cooked by electronic pan until they reached an internal temperature of $75^{\circ}C$. A total of 46 volatile compounds (6 alcohols, 6 aldehydes, 5 hydrocarbons, 6 ketones, 9 sulfur compounds, and 14 terpenes) from cooked beef patties were detected by using purge-and-trap GC/MS. The addition of nutmeg, onion, or ginger powder significantly reduced the production of the volatile compounds via lipid oxidation in cooked beef patty when compared to those from the control. Also, the addition of nutmeg and garlic powder to beef patty generated a lot of trepans or sulfur volatile compounds, respectively. From these results, the major proportion by chemical classes such as alcohols, aldehydes, hydrocarbons, ketones, sulfur compounds, and terpenes was different depending on the spice variations. The results indicate that addition of spices to the beef patty meaningfully changes the volatile compounds released from within. Therefore, it can be concluded that spices can interact with meat aroma significantly, and thus, the character of each spice should be considered before adding to the beef patty.

비닐하우스에서 생강재배시 종강의 크기와 재식거리가 생강의 생육 및 수량에 미치는 영향을 조사하였다. 비닐하우스 내의 기온은 노지에 비하여 평균 9$^{\circ}C$ 높았으며, 지온은 평균 2-4$^{\circ}C$ 높았다. 하우스 재배는 노지재배에 비하여 초장, 엽면적, 경수, 괴경 수량이 크게 증가하였다. 하우스에서의 재식거리 30$\times$30cm에서 근경수량은 노지보다 121-183%의 증수 효과가 있었다. 60$\times$30cm의 재식거리구에서는 재식거리 30$\times$30cm구에 비하여 감소하였으나 노지재배에 비하여 76-82%증수되었다. 단위면적당 근경수량은 재식 밀도가 30$\times$30cm이고, 종구의 크기가 40g 일 때(4,631kg/10a)가장 많았다.

생강 근경썩음병 길항균 Bacillus polymyxa 'HB26-5' 균주를 이용한 생물적 방제 가능성을 알아보기 위한 배양적 특성 및 제형화, 근권정착률을 조사한 결과 배양적온은 $25^{\circ}C$였고, 배지의 산도는 7.0에서 생육이 좋았으나 시간이 지남에 따라 초기에는 pH6.I~6.5의 약산성으로 되었다가 7일 후에는 pH7.8~8.2의 약알칼리성으로 변하였다. 길항균의 토양정착을 돕기 위해 첨가된 유기물중 쌀겨와 피트 또는 쌀겨와 카올린을 혼합한 제제가 토양처리 후 7주까지 길항균의 밀도 변화가 가장 작았다. 그러나 실제 노지포장에 처리하였을 경우 3주 후부터 밀도가 떨어지기 시작하였다. 제형의 경도,크기 등 물리적 특성과 길항균의 밀도유지 등을 고려할 때 알긴산 나트륨 2%, kaolin 15%, 쌀겨 3%를 혼합한 제형이 가장 우수하였다.

Kajami Shik-hae processing consists of the fermentation of low salted Kajami (6% NaCl maximum) coated with a vegetable mixture, composed with cooked millet, red pepper, garlic and ginger. Lactic bacteria are the main component of the microflora. In order to determine their eventual selective role on the microflora the antimicrobial activity of garlic and red pepper was tested with some strain of bacteria and molds isolated from Shik-hae and Shik-hae raw materials. And the influence of their concentration in Kajami Shik-hae on the microflora was also checked. At the concentration of 10% garlic have no inhibitory activity against lactic bacteria but on strains of Bacillus, Micrococcus and Aspergillus niger. At the concentration of 20% red pepper showed a slight inhibitory activity on two strains of Bacillus. These results shows that red pepper and garlic are not only flavoring ingredients but they might play an important role in the control of the microflora growth and composition during Kajami Shik-hae fermentation.

Folk Remedies symbolize the medical art of the common people, and contain their special emotion and colloquial expressions. They are medical treatments in which the medical history and the tradition and the soul of a people are incorporated. They are handed down in various ways. This study introduces some of folk remedies. For example, powder of tigers' bones heals neuralgia. Rice wine brewing up with ginger is effective in a cold. Water boiling with safflower does good in neuralgia. Pasting herba houttuyniae takes effect in skin disease. To Decoct and drink old hardy orange is effective in urticaria. Water boiling with fructus corni alleviates a fever. Camellia oil or rhizoma cnidii or iris is used for the extermination of vermin and the antiseptic. In the end, the practical application of these remedies to the resources of industry and education will be discussed.

[6]-Gingerol, a major polyphenol of ginger (Zingiber officinale), exhibits a variety of biological properties including anti-oxidant, anti-inflammatory and anti-cancer activity. However, the radioprotective effect of [6]-gingerol is still unknown. The aim of this study was to investigate the radioprotective effect of [6]-gingerol against radiation-induced cell cytotoxicity and oxidative stress in HepG2 cells. [6]-Gingerol pretreatment attenuated radiation-induced cell cytotoxicity caused by 5Gy (half lethal dose, $LD_{50}$ of HepG2 cells). The measurements of superoxide dismutase (SOD) and catalase (CAT) activity were also performed. The results showed that [6]-gingerol pretreatment reduced increasing SOD and CAT activity after exposure of IR, indicating that [6]-gingerol protected oxidative stress by regulating cellular antioxidant enzyme (SOD and CAT) activity. These findings suggest that [6]-gingerol acts as a radioprotector by attenuating cell cytotoxicity and oxidative stress.

분자압축탈수 방법을 이용하여 기존의 다른 건조방법보다 우수한 탈수 및 건조된 생강을 얻고자 생강을 이용한 분자압축탈수법에 탈수제(maltodextrin) 첨가량, 탈수시간, 절단 두께를 다르게 한 후 반응표면분석법으로 최적화하여 생강의 탈수 및 건조 최적조건을 얻고자 하였다. 분자압축탈수 방법을 이용한 생강의 탈수제 첨가량을 증가시킬수록 탈수율, 복원율, 관능적 특성의 외관(external), 향기(flavor), 조직감(texture) 및 전체적인 기호도(overall acceptability) 등은 증가하였으나 색(color)의 경우 낮아졌다. 또한 탈수시간, 절단 표면을 증가시킬수록 탈수율, 복원율, 관능적 특성이 증가하는 경향을 나타내었다. 분자압축탈수를 이용한 생강의 최적조건 범위는 탈수제 첨가량이 70-82%, 탈수시간이 5.2-9.2시간 이고 절단 두께가 1.0-1.2 mm로 설정되었다. 따라서 분자 압축탈수 방법을 이용한 생강의 최적 탈수 및 건조조건은 탈수제 첨가량이 76%, 탈수시간 7.2시간, 절단 두께 1.1 mm가 적당한 것으로 나타났다.
