Consumer are tend to pay their deep attention to pruchase a certain product, but in other product they havitually buy it in daily life. 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.

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/㎠.

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.
