박필숙,강진순,정승용,박재옥,김행자 慶尙大學校 1987 論文集 Vol.26 No.1

체중 60~65㎏의 wistar계 숫쥐에게 cholesterol 무첨가식이에 물과 kale 녹즙을 각각 급여하여 혈청중 총 cholesterol 농도, HDL-cholesterol 농도, 간장중의 총 cholesterol 농도, 혈청 및 간장중의 TG와 PL의 농도 그리고 과산화지질 농도를 측정하여 다음과 같은 결과를 얻었다. 1) 혈청중 총 cholesterol 농도는 cholesterol 무첨가식이군인 1,2군산 cholesterol 첨가이식군인 3,4, 5군간에서 각각 유의성이 없었다. HDL-cholesterol 농도는 cholesterol 무첨가식이군인 1,2군과cholesterol 첨가이식이군인 3,4,5군에서 kale 녹즙을 급여한 군이 유의적으로 높았다. 2)혈청의 중성지방농도는 전 군간에 유의성은 없으나 물ㅇㄹ 급여한 군보다 kale 녹즙을급여한 군에 있어 약간 낮은 경향이었다. 혈청의 인지질 농도는 cholesterol 무첨가식이군 및 cholesterol 첨가이식군 모두 물을 급여한 군보다 kale 녹즙을 급여한 군이 유의적으로 높았다. 3)간장의 총 cholesterol 농도는 cholesterol 첨가식이군에 있어 물을 급여한 군이 약간 낮은 경향이었다. 4)간장의 중성지방농도는 cholesterol 무첨가식이군에 비해 cholesterol 첨가이식군인 3,4,5군이 유의적으로 높았으며, 이들 군간에 있어서는 kale 녹즙혼액군이 비교적 낮았다. 간장 인지질농도는 cholesterol 첨가식이군인 3,4,5군간에 있어 kale 녹즙과 녹즙혼액을 급여한 3,4,군이 비교적 낮았다. 5)혈청 및 간장의 과산화지질농도는 cholesterol 첨가이식군인 3,4,5군이 무첨가식이군에 비해 대체로 낮았으며 또한 kale녹즙과 녹즙혼액을 급여한 군에 있어 유의적으로 낮았다. 이상의 결과로 보아 kale 녹즙의 섭취는 혈청 HDL-cholesterol 농도의 상승효과가 있고 간장 중 cholesterol 및 인지질의 농도를 다소나마 저하시키며 또한 혈청및 간장의 과산화지질농도의 지하작요이 있으므로서 혈청 및 간장의 지질개선효과가 있는 것으로 사료된다. The effect of kale juice, Brassica oleracea, on lpid components in serum and liver were investigated by feeding male rats of wistar for four weeks. And the concentrations of T-cholesterol,phospholipid, triglyceride and lipid peroxide in serum and liver were analysed along with the HDL-cholesterol concentration of serum . The results were as follows: 1)There was not found ny significant influence on the concentration of T-cholesterol in serum, butsome of relatively higher inluence but some of relatively higher influence on the HDL-cholesterol concentration. 2)For the group fed with 100% kale juice the concentration of triglyceride was shown lower than for any other groups, while that of phospholipid was shown higher. 3)The concentration T-cholesterol in liver was shown a little lower for the kale juice groups. 4)The concentration of triglyceride in liver was remarkably decreased in the 100% kale juice group in comparison with other groups, whiel the phospholipid concentraion was not. 5)Lipid peroxide values in serum and liver were relatively decreased in the kale juice groups compared to other group.

To obtain the spectral characteristics of a color monitor, we measured the spectral radiance curves of phosphors vs. digital values experimentally. The relationship between digital values and luminances is not linear. To predict the digital values needed to display specific colors, we presented a model using maximum and averaged values of each curve.

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.

The purpose of this stoury is to investigate The evaluative criteria and information sources of exporting Apparel products viewd from the Amercan Importers pespectice. The more specifically, of this study are to 1) Investigate for the order of priority in evaluative criteria when U.S. improters select the potential suppliers of product in Asian markets, and examination whether the evaluative criteria varies depending on the kind of importers and the level of product price. 2) Investigate for the order of priority when U.S. improters clarifiy information sources in Asian markets, and examination whether these imformation sources varies in accrdance with the type of importers and the level of product price. In this study, the measure instrument developed by the aid of the present researcher in the backgroud of previously made one. subjects are classified to the following : In domestic area, the questionnaires were sent directily to buyers from U.S.A., the questionnaire were sent to the members of AAFI, NATA and NAMP via air mail. And then, 87 copies of ansewrs were returned finally, and applied to statistical analysis by the usage of SPSS/PC for MEAN, percentage and one way ANOVA and Ducan test for post-hoc analysis. This study comes to the result as follows. 1. U.S. importers regards the following points as important evaluctive critera when they purchase product from suppliers in six countries of Asia. ; ① Product workmanship-quality, ② Reliability for delivery, ③ Product price, ④ Communications Channels, ⑤ Management control over production & technology. This resuly shows that U.S. importers deem as important points, not only price level but also benefits except price such as product quality, reliabilty for delivery andthe convenience of communicaton channels. According to the characteristics of importers, the major concernting points are changed. In general, importers for OEM deem the items such as product wordermanship- quality, social/political stabilization, convenience of communication channel, reputation of exporters in domestic area, and qupta & tariff as more important factors than retailers, import agency and buying offices do. In cpmpaison with the evaluative criteria for price zones, importers concerning budget price zone deem the items such like available of piece goods and trims as more important factors than importers concerning moderate and better do. On the other side, importers concerning moderate and budget price zone regard transportation fee as more important factors than importers concerning better do. Therefore, importers concerning moderate and buget price zone deem factors in price and production as more important than importers concerning better do. 2. The U.S. importers regard thd following items as important information sources ; ① Recommandation of import agency, ② Word of mouth, industry contacts ③ In-house market research or purchasing records, ④ Recommandation from trade associations and buing offices, ⑤ Direct presentation by salespeople Additionally, when using the information sources, the U.S. importers usually apply the neutral information from import agency or information related with buyers from word of mouth, industry contacts. In consideration of details, when comparing the usages of information sources by each type of importers, the manufacturer use more effiecently trade publications, recommandation from exporting countries' embassies, recommandation from bank, in- house market research or purchasing records than retaliers, import agency and buying offices do. In comparison with usages of information sources according to various of product price zones, the importers regard informations related to buyer such as word of mouth, industry contacts, in-house market research or purchasing records as more important factors as going to concern more expensive product.

Most persons who become infected with M. tuberculosis mount a protective immune response and remain clinically well, the only evidence of infection being development of a positive tuberculin skin test. Five to 10% develop tuberculosis disease within the first 2 years after infection (primary tuberculosis) or thereafter (reactivation tuberculosis). Acquired resistance against tuberculosis paradigmatically rests on cell-mediated immunity, with the major factors being mononuclear phagocytes and T Lymphocytes. While the former cells act as the principal effectors, the latter ones serve as the predominant inducers of protection. The usefulness of the single dose of BCG routinely given in childhood in many developing countries in preventing far more commonly occurring tuberculosis in adults is in doubt. An effective and safe vaccine against tuberculosis is sorely needed. A subunit vaccine are capable of inducing protective immunity and could have substantial advantages over BCG or other whole-bacterium vaccines. The human promyelocytic cell line HL-60 adopted characteristic macrophage-like properties, including adherence and CD14 expression after a period of continuous culture at high ambient CO_(2) concentration. When HL-60 cells were cultured with 1,25-dihydroxyvitamin D_(3) for 4 days, the cells acquired the activity to potentiate T cell proliferation by the 30 kDa or 38 kDa antigen of Mycobacterium tuberculosis H37Rv Therefore, vitamin D-treated HL-60 cells showed the function of the antigen presenting cells.

To be successful, Korean exporters must understand how importers identify and select suppliers. This empirically based study investigate Korean exporter's perceptions of the supply selection criteria and information sources in US importers use. The specific purposes of this study were to identify the importance of the supply selection criteria and information sources and to examine the effects of the amount of export on the supply selection criteria and information sources in US importer use. For this study, data were obtained from Korean exporters by means of self-administered questionnaires. The questionnaires consisted of a series of statements covering a broad of specific selection criteria and information sources and exporters' characteristics including average annual amount of export. Using a base of 312 exporters, data were analysed by using mean, one-way ANOVA, and Ducan test. Major findings of this study summarized as follows; 1) Korean exporters perceived that US importers would place importances on product price, deliverly reliability, product wordsmanship-quality, and length of deliverly lead-time, in orders. Also, The more amount of export was, the higher product wordsmanship-quality, availability of piece goods and trims, and communication channel were importantly rated. 2) Korean exporters considered the third party sources, such as recommendation from trade association and buying office and import agency, as the most important information source in US importer use. Also, There was tendency that the more amount of export was, the more information sources on suppliers was importantly evaluated. From this study, several recommendation were suggested forward to encourage export in international apparel market.
