The purpose of this study is to identify difference that might exist between married woman's buying motivations for imported and domestioc formal two piece suits and to test the role of socioeconomic variables on those differences. Samples selection criteria included married women living in Seoul, Korea, between ages 30 ∼ 59. Purposive sampling method was used to secure sespondents with experience with imported formal two-piece suits. Of 400 distributed. 246 usable questionnaires were returned. Statistical analysis of results included factor analysis, and paired t-tests. For both imported and domestic suits, the most important buying motivation was utilitarian, with quality the most important consideration. Purchases of domestic suits were more influenced by factors such as advertisements, economics, impulse buying, approval of others, and current fashionability of style than were the purchases of imported suits. On the other hand, purchases of imported suits were more influenced by factors such as prestige and utilitarian motivation than were purchases of domestic suits. For most socioeconomic variables, respondents indicated significant differences in their motivations for buying imported suits and domestic suits. The results of this study suggest the need for implementing different marketing strategies for imported suits and domestic suits.

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.

Y??NdxBa₂Cu₃O?? 고온초전도체의 X-선 회절 분석 과 적외선 투과율 측정은 실온에서 수행되었다. 또한 수송임계 전류밀도는 77K에서 측정되었고, 저항은 80~140K 범위의 온도에서 조사되었으며, 시료들은 고상 반응법에 의해서 제조되었다. 한편 x의 양이 변함에 따라서 전이온도 Tc는 88K 근처의 값을 가지며, 거의 x의 양에 따라 변하지 않았다. 적외선 투과율 측정에서 날카로운 peak들은 472.23~618.87㎝?범위에 있었다. 이것은 특이할 정도로의 low-lying plasmalike edge와 낮은 에너지의 전자적인 여기가 존재함을 나타내는 것이다. 수송임계 전류밀도는 22~92 A/㎠ 범위에 있었다. X-ray pellet diffraction and IR transmittance measurements were been carried out at room temperature. Also the transport critical current density and resistivity of high Tc superconducting Y??NdxBa₂Cu₃O?? system were determined at 77K and in the range of 80~140 K. The sample were prepared by solid state recation. As x varied, the superconducting transition temperature Tc near 88K did not depend on x. In the infrared transmittance measurements, several sharp peaks were observed in the range of 472.33~618.87㎝-1. This indicates that unusual low-lying plasmalike edge and low energy electronic excitation exist. The transport critical current densities determined ranged from 22 to 92A/㎠.

The purpose of this study is to find out problems in obesity management through survey and analysis of the actual conditions from the view of a elementary schools school-nurses and to establish fundamental data for efficient obesity management. The subjects for this study were 313 numbers of elementary school-nurses in Kyung-Sang-Pook-Do. The data were collected through mail questionaries from November 1 to November 30,1997. The major findings in this survey were as follows:49.8% of the school-nurses who responded in the survey were in their 30s. The average career was 7.3years. The average service duration in their present school was 2.3years 55.6% of them were serving at schools which have less than ten classes total. 77.2% of them were serving rural areas, 79.6% of them were serving at schools with fewer than 100 obese students. The total obesity prevalence rate was 11.4%, 13.3% were girls, 9.3% were boys. The measurement of height and weight is performed once a year for all surveyed students(91.7%), but obese students were measured as much five times(51.1%). The rate of obesity management planning was 74.1%,however the rates of evaluation and role assignment were 41.2%, and 24.3% 79.6% of the surveyed schools have health education classes for obesity, the rate compared(8.0 periods per year) to the whole of health education(79.1 periods per year) is 10.1%. 99.9% of the schools had counseling rooms for obesity (combined with nursing rooms) but they were used. The roote of individual counseling was 84.3%. The frequency counseling was six times a year for about 15 minutes. Obesity counseling records were kept 93.6% of the time and individual information cards were kept 98.7% of the time. The frequency of parents counseling was 42.8% and the survey shows that the main problem here was insufficient counseling facilities. The frequency of dietary guidance and exercise therapy was 84.3% and the dietary instructor was usually the school nurse at 51.7%. The frequency of obesity student exercise was 1~2 times a week and more-than-10minutes at a time. They skip rope during the morning self-study class. The number on problem of exercise guidance at 56.2% was students' non-cooperativeness. School-nurses,87.9%, answered that obesity management at school is necessary and 86.9% mentioned the shortage of obesity related information in present physical exercise books. From the plural responses of executing the obesity management, there are many similar problems; lack of knowledge and non-cooperation in parents at 41.9%, is predominant followed by of knowledge and non-cooperation in the children. The third problem is the lack of funds and facilities.

박진철,옥민,차재영,조영수 한국응용생명화학회 2003 Applied Biological Chemistry (Appl Biol Chem) Vol.46 No.4

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.
