Seven triterpenoid saponins such as oleanolic acid 28-O-{\beta}-D-glucopyranosyl$ ester, hederagenin $28-O-{\beta}-D-glucopyranosyl$ ester, chikusetsusaponin IVa, udosaponin A, salsoloside C, udosaponins F and C were isolated from the aerial parts of Aralia continentalis, among which two $28-O-{\beta}-D-glucopyranosyl$ esters of oleanolic acid and hederagenin are isolated for the first tome from this plant. These results suggested that the chemical components of Korean Dokwhal are practically identical to those of japanese Udo supporting the chemotaxonomical point of view.

Welding of dissimilar materials is an area of growing importance in the automotive, aerospace, electronics medical and other domestic appliance industries. This study investigated the ultrasonic welding of dissimilar polymers. Two amorphous and two semicrystalline polymers were used, utilizing all possible welding combinations. For each combination of dissimilar materials, the weldabilitys of the joint was evaluated as a function of weld time, amplitude of vibration and pressure. The joint was also examined microscopically to analyze the melting and flow of the materials. It was generally around found that welding of amorphus polymers resulted in very poor joints. Welding of the amorphous polymers together and welding of the semicrystalline polymers together produced good joints.

1, 1-diamino-3, 3, 5, 5-tetrachlorocyclotriphosphazene, 1, 1-diami-no3, 3, 5, 5-tetra-(p-bromophenoxy)cyclotriphosphazene, and 1, 1-diamino-3, 3, 5, 5-tetra-(p-chlorophenoxy) cyclotri-phosphazene(ACPP) was prepared from hexachlorocyclotriphosphazene and used for the curing agent of bisphenol A type epoxy resin and phenol novolak. The resistance to chemicals and water of the cured epoxy resins were examined by DMTA and compared with those of the epoxy rosins cured with phosphazene derivatives and 4, 4'-diaminodiphenylmethane. The effect of the curing agent on resistance to chemicals and water of the cured epoxy resins were investigated. The epoxy resins cured with 1, 1-diamino-3, 3, 5, 5-tetrachlorocyclotriphosphazene and 1, 1- diamino-3, 3, 5, 5-tetra- (p-bromophenoxy)cyclotriphosphazene showed superior resistance to chemicals and water to those of 1, 1-diamino-3, 3, 5, 5-tetra- (p-chlorophenoxy)cyclotriphosphazene and 4, 4'-diaminodiphenylmethane. It is an effective curing agent for epoxy resins to enhance the resistance to chemicals, water and tome proofing.

The objectives of this study are to give a definition and to find out the background and the pursuits of Saenghwal Hanbok. Conclusions are described as follows : 1. Saenghwal Hanbok and Gaeryang Hanbok are used together at the same tome, but they are different the background and the pursuits. Gaeryang Hanbok was pursued practical aspects - activities, simplification, sanitation, courtesy, economy, and diversity. And then Saenghwal Hanbok was added the pursuits of Minjung's image, traditional image, modern esthetic. 2. The background of Saenghwal Hanbok is divided into two group. One is the Minjung Hanbok in University, and the other is the recreated Hanbok in mass fashion. The former was effected to youth culture, political quarrel of culture movement, anti-government group. The Latter was a tendency toward reviving the tradition. 3. The characters of Saenghwal Hanbok were a national tradition, a resistance. the image of poor Minjung, a revival of the tradition, and a diversity and negotiation of post-modernism.

Electrospinning is emerging as a simple means of producing fibers with diameters ranging from 0.02 $\mu\textrm{m}$ to many microns. Electrospinning, however, relies on the force generated by an electric field on the surface of a polymer solution to either enhance instabilities in a thinning jet or to rapidly elongate a jet of polymer solution form a nozzle. In this article the fundamental physics and fluid dynamics on the subject matter are described, and tome of the relevant parameters in electrodynamic instabilities at polymer interfaces are discussed in some detail.

In viewpoint of visual merchandising, display is recognized as important means of expressing fashion as well as essential factor of stimulating customers' interest in purchase. However, visual merchandising Is relatively new area and the number of specialized display personnels are limited Therefore, the purpose of this study was to investigate the practice of display in domestic fashion industry. For this study the display personnels working in 51 fashion brands were interviewed. The result was analyzed by using frequency count and percentage. It was found that few human resources were undertaking display work in various and abundant stores with relatively frequent display replacement. And main part of display work was performed outside office hours which brought out extension of working tome. Comparatively more budget assigned for ladies 'brand than mens' brand, youngsters 'than middle-ages' and obtaining display-related information was belong done mostly via domestic documentary sources and market researches. In general, optimistic attitudes were significantly shown by the interviewees that the importance of display is increasingly recognized, in the domestic fashion industry and therefore the prospect of display found to be expected as prosperous.

This study is to study the peculiar world of work that endeavored the stage setting and costume production in Ballet-russe centered around one of 20th representative artist Pablo Picasso and Diaghilev. Picasso worked four pieces ballets such as parade, Le Tricorne, Puchnella, and Le train bleu with Diaghilev. The originality of costume was well represented without losing the whole work's sense of unity. and designed foreasy movement as well as visual effect. As cubic is most common in parade especially, cubic stave costume were introduced at dancing costume of Paris manager and New York manager flrst time in Ballet's history. Picasso used the Cubism for dancer's beautiful appearance and primary color and decoration for oriental feeling. Picasso pursued the beauty and action at the same tome, and tried to represent the stage setting, impersonation and costume towards units, so the Importance of his work has still been referring.

Generally, X-ray examinations for dentistry use low energy radiation. It explains that the radiations are mainly absorbed to a human body because of the weak permeability. We made up some counterplans for decrease in radiation exposure, when guardians and radiologists are overexposed owing to unavoidable circumstances. The equipments for the test are GX-770 and CRANEX TOME CEPH which are used for various exams. Besides we measured the radiations in the projection room and in the control room using model 2026c and 20X6-1800. According to the test, the measurement value in the control room was low dose below $20{\mu}R$, the maximum dose in the projection room was $702.8{\mu}R$ and the measurement value of back dose was higher than lateral one. As the result, if we use a shielding door, it's effective for radioprotection and when we didn't prepare protectors, we should secure appropriate distance and be situated at the side area($90{\sim}135^{\circ}$) on the basis of centeral radiation. That way will provide valuable aid for radioprotection.

The material properties of crack growth models at an elevated temperature were derived from the results of numerous crack growth tests for Mod.9Cr-1Mo (ASME Grade 91) steel specimens under fatigue loading and creep loading at an elevated temperature. These crack growth models were needed for defect assessment under creep-fatigue loading. The mathematical crack growth rate models for fatigue crack growth (FCG) and creep crack growth (CCG) were determined based on the test results, and the models were compared with those of the French design code RCC-MRx to investigate the conservatism of the code. The French design code RCC-MRx provides an FCG model and a CCG model for Grade 91 steel in Section III Tome 6. It was shown that the FCG model of RCC-MRx is conservative, while the CCG model is non-conservative compared with the present test data. Thus, it was shown that further validation of the property was required. Mechanical strength tests and creep tests were also conducted, and the test results were compared with those of RCC-MRx.
