본고는 미암 유희춘이 유배지에서 저술한 "속몽구분주(續蒙求分註)"에 대해 "몽구(蒙求)"와 차이를 가지는 분주(分註) 방식을 시험적으로 고찰하여 그 학술서로서 성격을 규명하고자 하였다. 이에 먼저 "속몽구분주"와 "몽구"의 본문 구성에 차이가 있는 점을 들어, "몽구"가 각 편마다 인용출처를 제시하고 인물 일화 중심으로 본문을 구성하였다면, "속몽구분주"는 인용출처를 맨 앞에 한꺼번에 제시하고 본문에서 일화 소개와 함께 분주의 방식을 취하였음을 밝혔다. 이어서 "속몽구분주"의 분주 방식을 자세히 살펴, "속몽구분주"가 네 가지의 분주법(分註法), 곧 소유이궁원(?流而窮源), 분원이지류(汾源而至流), 누사이일의(累事而一意), 이동이호발(異同而互發)에 따라 분주한 방식에 대해 각기 해당하는 예를 들며 살펴보았다. 이로써 "속몽구분주"가 경사자집(經史子集)의 여러 서책을 출처로 하였으되, 특히 주자의 평과 그 당대 학맥에 속하는 인물들의 언급을 많이 참고하였음을 확인할 수 있었다. 그리하여 "속몽구분주"가 주자학에 철저한 학술서이자 유서(類書)로서 학자들이 이용하기에 편리하게 이루어진 저술임을 밝혔다.

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.

일반적으로 저 에너지 방사선 조사로 검사하게 되는 치과 영역에서는 투과력이 약해 인체에 흡수되는 양이 많다. 치과 영역에서 방사선검사 시 부득이하게 방사선 노출을 받게 되는 방사선 작업종사자나 환자의 보호자가 위치와 거리에 따른 방사선 피폭 선량의 감소 방안을 알아보고자 한다. 진단용 발생장치인 GX-770, CRANEX TOME CEPH와 조사선량 측정기인 Ion chamber model 2026c, Reader기 20X6-1800을 사용하여 구강내 검사와 구강외 검사의 각각 검사실과 조정실에서의 관전압의 변화, 관전류와 조사시간의 변화, 조사방향의 변화에 따라 선량을 측정하였다. 그 결과 최고선량이 검사실 안에서는 평균 702.8 ${\mu}R$으로 측정 되었으며, 조정실 안에서 측정하였을 경우 20 ${\mu}R$이하의 낮은 선량을 보였으며, 120cm 거리에서 후방검사보다 측방검사가 낮은 선량으로 나타났다. 방사선검사시 위치와 거리에 따른 조사선량을 비교 분석하여, 적절한 거리 확보와 조사되는 중심방사선을 기준으로 측방($90{\sim}135^{\circ}$)에 위치함으로써 방사선 방어에 도움을 줄 것이며, 차폐문을 이용하여 방사선 피폭으로부터 감소 효과를 볼 수 있을 것이다.

본 연구에서는 피로 하중 및 크리프 하중을 받는 Mod.9Cr-1Mo (ASME Grade 91)강 시편에 대한 일련의 실험결과로부터 재료물성치인 고온 균열진전 모델을 개발하였다. 이 균열진전 모델은 크리프-피로하중을 받는 균열체의 결함평가에 사용되는 물성치이다. 한국원자력연구원이 수행한 일련의 피로 균열진전(FCG) 속도 실험 및 크리프 균열진전(CCG) 속도 실험 결과로부터 균열진전 모델을 결정하고, 이를 프랑스의 고온 설계 기술기준인 RCC-MRx 와 비교함으로써 설계 물성치의 보수성에 대해 검토하였다. RCC-MRx 는 FCG 모델 및 CCG 모델을 Section III Tome 6 에서 제공하고 있는데, 실험으로부터 결정한 균열진전 모델과 비교한 결과 RCC-MRx 의 FCG 모델은 보수적인 것으로 나타난 반면 CCG 모델은 비보수적인 것으로 나타나 동 물성치에 대한 검증이 필요한 것으로 나타났다. 또한 본 연구에서는 기계적 강도 및 크리프 시험결과에 대해서도 RCC-MRx 의 물성치와 비교 및 분석하였다.
