본 연구에서는 glutathione(γ-L-glutamyl-cysteinlyl-glycine)을 다량으로 함유하는 효모 균주를 전통 발효주로부터 분리하여 glutathione 생산 조건을 검토하였다. 분리된 균주는 형태학적, 생리학적 및 생화학적 특성을 검토한 결과 Saccharomyces cerevisiae로 동정되어 FF-8로 명명하였다. Saccharomyces cerevisiae FF-8의 glutathione 생산 조선을 YM(glucose 1.0%, acid peptone 0.5%, yeast extract 0.3%, malt extract 0.3%) 배지를 기본으로 하여 최적 온도, 교반속도 및 초기 pH의 조건을 검토하였다. Glutathione 생산은 30℃, 교반속도 100rpm 및 pH 6.0에서 72시간 동안 진탕 배양하였을 때 가장 높았으며, 이때 glutathione 생산량은 72.0㎎/ℓ이였으며, 건조 균체량은 5.2g/ℓ이었다. In this study, strain of high-producing intracellular glutathione was isolated from Korean traditional rice wine. The isolated strain was identified as Sacharomyces cerevisiae based on the morphological, physiological and biochemical characteristics, and was designated as FF-8. The optimal condition for glutathione production by Sacharomyces cerevisiae FF-8 was obtained after cultivation with shaking for 72 hours in the YM medium. The optimal temperature, shaking rate and initial pH for the glutathione production were 30℃, 100 rpm and pH 6.0, respectively. The dry cell weight and glutathione concentration produced by Sacharomyces cerevisiae FF-8 were 5.2 g/ℓ and 72.0㎎/ℓ, respectively, under the optimal culture condition.

Hence, in establishing marketing strategy it is important to estimate the level of consumer's involvement for a product and to understand their preference. The purpose of this study is to investigate the relationship between clothing purchansing behavior and the level of consumer's product involvement. specifically this study was intended to examine the following points. 1) This study classifies the apparel products aecording to consumer's product involvement level high involvement product group and low involvement product group. In complience with the variables which are resulted by consumer's intrest and their situations : 2) Whether there is any difference in consumer's purchasing behaviors (i.e. information source, unmber of stores at purchasing, hour consumed at shopping) with respecto to information source. 3) Whether there is any difference in influence from their companies or reference groups. 4) Whether there is any difference between unplanned purchasing and other purchasing behavior (unplanned purchasing and its reason, number of purchasing and pattern of payment). The subjects are 340 housewives who have middle school or high school student in seoul. The instrument includes the clothing product involvement and demographic information measure in the background of previous research. As the method of investigation, questionaires have been used and in data analysis, to get the frequency, mean, percent, xtest, SPSS / PC has been used. The result of this study has been summarized as follows. 1) First, in reference with measuring the level of involvement, clothing product have been classified to five groups according their purposes. The formal wear for going out have been classified to high involved product, while the other such as night-clothes, Langery, sport wear, underwear and casual wear to low involment product. 2) With regard to the activity for getting information according to the level of involvement : ① When getting the information source of perching, and low involvement product, even though it is high or low involvement product, varied on the information from past purchasing experience and showwindow displayed product. ② From the viewpoint of amount the activity for getting information, they visit more number of stores when buying the low involvement product. ③ The level of clothing involvement influences the consumed for shopping. Consumers invest mere hours for purchasing the high involvement product than the low involvement product. 3) Regarding the influence from companions or reference group to the level of involvement : ① Especially, the kind of companions depends on the level of involvement Usually consumers acompany their close acquaintence when purchasing high involvement product, while the order of priority is 'alone' and 'close acquaintence' when pruchasing low involvement product. ② Without regard to high involvement product. ③ In influence from the reference group, the type to be considered varies depending on the level of involvement. when purchasing low involvement product, consumer tend to be influenced from their mates. But consumer tend to be influenced from their close acqintances or coworkers in the company when purchasing high involvement product. 4) In reference with unplanned purchasing or various purchasing, according to the level of involvement : ① First, when unplanned purchasing, there are somewhat different tendencies. But, in case of their unplanned purchasing, they tend to purchase the product impulsively. ② In reference with the unplanned purchasing, no difference appears between the level of product involvement. But, the major reason of the unplanned purchasing is 'cheaper than expected' in both cases, high and low involvement product. ③ In number of purchasing, there is difference between the level of involvement for product. generally low involvement product is more frequently used by housewives when purchasing high involvement product than when low involvement product. ④ In the pattern of payment, there is the difference depending on the level of the involvement for the product credit cards are more frequently used by housewives when purchasing high involvement product than when low involement product.
