The purpose of this research is to find out the dominant factor determining exchange biased field and characteristics of Ni-Fe/Mn-Ir/buffer/Si bottom structure. We found out that the H_(ex) and the H_c of Ni-Fe/Mn-Ir multilayers depended on the grain size of Mn-Ir layer and the grain-to-grain epitaxy relationship at the interface between Mn-Ir and Ni-Fe layers. The blocking temperature, at which the exchange biased field disappears, of top structure was about 220℃ and that of bottom structure was about 180℃. The grain size of Mn-Ir layer in bottom structure is smaller than that in top structure. The bottom structure has more magnetic dead layer and less alignment of spin of the Mn-Ir layer than top structure.

So far, there has been minimal research regarding Korean wave which was focused on music, film and fashion in Japan and China. In the present paper, we compared Korean wave about music, film and fashion between Japan and China. We took a sample of 363 Japanese peoples and 272 Chinese peoples. The results are as follows. First, perception of Korean wave about music positively impact on image of Korean consumer goods in Japan and China. Second, perception of Korean wave about fashion positively impact on image of Korean consumer goods, but does not directly impact on attitude of Korean consumer goods in Japan. Third, perception of Korean wave about music does not significantly impact on image and attitude of Korean consumer goods in Japan. But, perception of Korean wave about music significantly impact on image and attitude of Korean consumer goods in China. Fourth, we found that image of Korean consumer goods and attitude of Korean consumer goods has a positive relationship in Japan and China. Also, attitude of Korean consumer goods and purchase intention of Korean consumer goods has a positive relationship in two countries. Besides, we demonstrated that image of Korean consumer goods directly impact on purchase intention of Korean consumer goods. Finally, this study found that Korean wave about music has a much stronger influential to people in Japan But, Korean wave about film and fashion have even stronger influential to people in China. This study provides useful implications to not only central and local government but also many companies. 본 연구는 지금까지의 연구와는 달리 한류를 영상한류, 음악한류, 패션한류로 분류하였으며 또한 단일국가를 대상으로 연구한 것이 아니라 일본과 중국 두 나라의 국가 간 비교 연구를 실시하였다. 일본과 중국의 소비자 각각 363명과 272명을 대상으로 실증분석 하였으며 연구결과와 시사점은 다음과 같다. 첫째, 일본과 중국 모두 음악한류 지각이 한국 소비재 제품 이미지에 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 패션한류 지각은 일본 시장의 경우 한국 소비재 제품 이미지에 양(+)의 영향을 미치지만 한국 소비재 제품 태도에는 직접적인 영향을 미치지 못하는 것으로 나타났다. 셋째, 영상한류 지각의 경우 일본 시장에서는 한국 소비재 제품의 이미지와 태도에 모두 유의한 영향을 미치지 못하는 것으로 나타났으나, 중국 시장에서는 모두 한국 소비재 제품의 이미지와 태도에 양(+)의 영향을 미치는 것으로 나타났다. 넷째, 일본 시장과 중국 시장 모두 한국 소비재 제품 이미지가 한국 소비재 제품 태도에, 한국 소비재 제품 태도는 구매의도에 각각 양(+)의 영향을 미치는 것으로 나타났다. 또한 한국소비재 제품 이미지는 구매의도에 직접적으로 양(+)의 영향을 미치는 것으로 나타났다. 마지막으로 본 연구는 중국과 일본 시장의 소비자를 대상으로 탐색적 차이 분석을 하였는데, 음악한류의 경우는 일본의 경우가, 영상과 패션한류의 경우는 중국의 경우 더 큰 영향을 미치는 것으로 나타났다.

In order to study the effects of Daebangpungtang on galactosamine induced hepatoxity in rats, the experimental rats divided five groups (Normal, Control, Sample A, B, C groups). Under the same condition, normal and control groups were administered normal saline for 16 days, control group was injected to abdomen with galactosamine at 8th day (800mg/kg). Sample A group was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) for 8 days and injected galactosamine(800mg/kg i.p) for the last day and was administered normal saline for 8 days. Sample B group was treated as same as group A for 8 days, and then was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) forfurther 8 days. Sample C group was administered the Daebangpungtang aqueous solution($200m{\ell}/kg$ p.o) for 16 days. The activity of GOT, GPT, ${\gamma}$-GTP, ALP, LDH and total bilirubin in serum were measured at 8th and last day. The results were obtained as follows: 1. The activity of serum GOT of the sample A group decreased effectively at the 8th day and sample B group decreased effectively at 16th day as compared with the control group. 2. The activity of serum GPT of the sample A group decreased effectively at the 8th and 16th day and sample B group decreased effectively at 16th day as compared with the control group. 3. The activity of serum ${\gamma}$-GTP of the sample B group decreased effectively at the 16th day as compared with the control group. 4.

The intelligence is the capacity to recognize the things and implies the meaning of abstract thought, learning and adaptability to the circumstance. Recently, as the promotion of learning ablility and memory attracts many people's attention, many studies of this have been accomplished but the pharmacological methods could not promote the intelligence and memory. In oriental medical theory, the human body is composed of four elements - essence, energy, sprit, blood and among these elements, sprit is considered as the concept of vital energy and mind. Especially, from the Jang-Fu physiological point of view, the memory is closly related with the heart and kidney In oriental medicine, some experiments on animal and literature studies on the subject of memory promotion have done. But because of difference in memory mechanism between man and animal, it is not in reason to apply the result of experiment on animal to human. Therefore I have methodological study of memory promotion to set up the concept of oriental medicine and experimental theory about this and can obtain such conclusion. 1. The oriental medical therapy for memory promotion is following. nourishing the heart and blood, regulating the function of spleen, relieving the mental stress, reinforcing the heart and kidney, invigorating and enriching the blood. 2. The insufficient intelligence in a child is considered to not be full and in an old man, it is considered to decline by degrees. 3. It is needed to molecular biological study of neurotransmitter after the using of oriental medical therapy. 4. It is possible to study using the genetic mutation or observing the collateral of brain nerve cell.

It has long been known that Jahage(紫河車) extracts of Placenta hominis are effective for immunological and vascular diseases in human body and thus, was used a major constituent of traditional oriental medicines. From full-term human placenta, we have purified a new type anticoagulant protein, PP27, using different chromatographic techniques of a phenyl TSK gel 650M column, DEAE, HA and Mono-Q columns. PP27 showed single band on SDS-PAGE with a molecular mass (Mr) of 27 kDa under denaturing conditions and a calibrated Sepharose 4B column chromatography indicated a molecular mass of 23 kDa, indicating that the value is similar to those of other PP4 enzyme reported to date. Isoelectric point of PP27 was p15.2. The protein was found to inhibit the coagulation time in a concentration-dependent manner. PP27 was acted as a vascular anticoagulant of annexin type, inhibits the blood clotting process by binding of the essential lipids in a reaction which is dependent on $Ca2^+$ ions. In the presence of $Ca2^+$ ions, PP27 combines with platelet membranes neutralizing their procoagulant effect. Coagulation triggered by the addition of thromboplastin/ lipid- mixtures is extinguished by PP27.

This study was to investigate the relationship of headache and back shape using the Moire interferometer and Questionnaire investigations. In this study the subjects consisted of 317 pupils[168 boys(53%), 149girls(47%)] attending S high school in Sungnamsi, Kyoungkido in 2002, and their ages ranged from sixteen to eighteen. The results are following. 1. In questionnaire investigation, we observed that the ratio of headache was more than 70% and the ratio of girls are more than that of boys. The inclination for ages was not shown. 2. In moire topography, the remainder values of scapular region were from 0.5 cm to 1.1 cm in boys, and from 0.45 cm to 1 cm in girls. The remainder values of gluteal region were from 0.2 cm to 0.8 cm in boys, and from 0.4 cm to 0.6 cm in girls. The reminder values of the vertical lines of cervical and buttock region were from 0.71 cm to 1.51 cm in boys, and from 0.96 cm to 1.43 cm in girls. More frequent findings of reminder value of the vertical lines of cervical and buttock region were observed that the vertical lines of cervical region were inclined to left than the vertical lines of buttock 3. Through the Pearson's Correlation analysis of headache and Moire topography, we found the close relationship of headache and the remainder values of scapular region(Pearson correlation coefficient : 0.116, P<0.05) and gluteal region(Pearson correlation coefficient : 0.153, P<0.01). But the relevances to headache and the remainder values of neck lines, sacral lines and neck-sacral lines were not found.
