Since the mid of 1980's, cultivation area and production of Ganoderma lucidum have been increased annually in Korea. However, the presence of a fungal disease has become a major limiting factor in the cultivation of Ganoderma lucidum, causing a serious economic loss. The present study was carried out to isolate and identify the pathogenic fungus to Ganoderma lucidum. Several fungi isolated from the wood logs showing typical symptoms were tested whether they are pathogenic to Ganoderma lucidum or not by cross-pairing culture method, flask inoculation method, and wood log inoculation method. The pathogenic fungus produced ascomata. Mature ascomata was spherical, dark, thick-walled, $45{\sim}95\;{\mu}m$ diameter. Asci were thin-walled, evanescent when mature, disintegrate early. Ascospores were spherical, hyaline, glaborous, thick-walled, refractive, $3.6{\sim}4.3\;{\mu}m$ in size. Conidiophores soon became abundantly septate and broke up into arthrospores, which are cylindrical, $3{\sim}6\;{\mu}m$ long and $3{\sim}4\;{\mu}m$ wide. Based on the observations under dissecting microscope, light microscope and scanning electron microscope, teleomorph and anamorph of the pathogenic fungus were identified as Xylogone sphaerospora Von Arx & Nilsson and Sporendonema purpurascens (Bonordon) Mason & Hughes, respectively. X. sphaerospora is first reported as a pathogenic fungus of Ganoderma lucidum.

The industrial development of Goryeong County was started by the operation of the Ssangrym Agro￢industrial complex in the 1980s. As of 2m3, there are 6 industrial complexes in Goryeong County which account for 80 percent of total employment and 67 percent of total production outPuts in local manufacturing. The local manufacturing industries grew steadily before the 1997 financial crisis which resulted in industrial decline and have shown again a growing tendency since 2000. In this period of growth, manufacturing outPuts are increased and the industrial structure are improved, while employment and value added are in stagnation. The major industrial agglomerations are based in Gaejin-Myun, Dasan-Myun and Ssangrym-Myun, all of which are those in which the agro-industrial complex is operated. More than half of local manufacturing finns are those which came to move in from other regions, looking for cheap labour forces, agglomeration of the related finns and the easy accessibility to transport and communication. However, such local advantages are increasingly losing due to the shortage of labour forces and the lack of industrial networks. Some policy agendas can be suggested as follows. First of all, industrial policy should attempt links with the building-up of the Daegu Technopolis and the up-grading of the local industrial structure towards the knowledge-based industries. Secondly, the local government should make efforts to establish the innovation supporting system for local firms and the industrial and residential basis.

After independence, more introductory books on Korean culture were published in both Korea and Japan, along with various papers briefly presenting relevant materials. There are differences depending on the research field, however, a considerable number of articles about Buddhist paintings were published. Research on Korean sculpture was quite active among Japanese scholars. And numerous articles and publications on Korean painting were also presented in both Korea and Japan. Publications on Korean ceramics were increased as much as in other fields. From the late 1980's through late 1990's, research on Korean cultural properties continued to increase, as many young scholars began to conduct research very actively in Korea, producing many articles to introduce new materials. A small number of Japanese scholars also continued to research Korean cultural properties. The overall number of Korean researchers also increased, as existing scholars were joined by students who went to Japan to study and conduct research, thereby helping to significantly expand the area and topics of research. In this period, the exchange exhibitions between Korea and Japan were increased. Also the substantial research reports was began to be published by the national institution. From the early 2000 thrugh present, in all fields, research has progressed and improved since the late 1990's, with many individuals pursuing a microscopic approach to their artifacts and works. More graduate students have been focusing on Korean cultural properties in Japan as the subject of their master's or doctorial thesis in art history, and overall number of researchers in various areas has increased. In the field of Buddhist painting, painting, and Buddhist crafts some important books and articles have been published. However, research achievements have been somewhat uneven. In the area of ceramics, several significant examples of substantial research reports were published by the National Research Institute of Cultural Heritage. These publications are outstanding references that illustrate the future direction of research on Korean cultural properties in Japan.

우리나라의 소득분배문제에 대해서 종래에는 적어도 1980년대 이후 개선되고 있으며, 국제비교에서도 다른 나라에 비해 결코 나쁘지 않다는 평가가 주류를 이루고 있었으나, 최근에는 그에 대한 반론이 만만치 않게 전개되고 있다. 본고에서는 "도시가계연보"의 원자료를 이용한 새로운 추계를 시도하여 1980년대의 소득분배가 지금까지의 통설처럼 그렇게 많이 개선된 것은 아니라는 결과를 제시하였다. 마찬가지로 일부의 반론처럼 1980년대의 소득분배가 실제로 악화되었다는 주장도 과장일 가능성이 크다는 점도 지적하였다. 단, 근로소득의 분배가 개선되고 있음은 분명하나 토지나 주식 등에 의한 불로소득까지 포함하면 결과는 크게 달라질 수 있다. 이 문제의 검증은 아직 끝난 것이 아니며, 올바른 결론에 도달하기 위해서는 앞으로 보다 많은 자료들이 발굴, 분석되어야 할 것이다. 한국의 자산분배에 대해서는 지금까지 자료가 별로 없어서 논의 자체가 어려운 상태였다. 최근 대우경제연구소의 패널 자료를 분석해본 결과, 한국의 부의 분배는 지금까지 알려진 것보다 훨씬 더 불평등하며, 특히 토지 등 실물자산의 불평등이 심각한 것으로 나타났다. 한편 한국의 빈곤은 많이 줄어든 것이 사실이며, 다른 후진국과 비교해서 빈곤 축소에 큰 성과를 거둔 것으로 평가된다. 본고에서 좀더 현실적인 최저생계비를 가정하여 분석해본 결과 한국의 빈곤은 물론 많이 줄어들었지만 아직 상당히 남아 있으며, 빈곤의 크기 자체(빈곤 갭)는 그다지 크지 않은 것으로 나타났다. 본고에서는 이러한 연구결과에 기초해서 우리나라의 분배문제에 대한 평가를 내리고 효율성과 형평성의 조화라는 관점에서 정책의 기본방향을 설정하였으며, 조세정책가 재벌정책에 초점을 맞추어서 정책방향을 논의하였다. 분배정의 관점에서, 우리나라의 세제는 직접세 비중을 높이고, 종합토지세, 상속 증여세 등 재산관련 세제의 기능을 강화하며, 근로자와 비근로자간 세부담의 형평성을 제고하는 방향으로 개편되어야 한다. 그리고 재별의 소유분산 자체보다는 재벌이 자행할 수 있는 경제적 부조리를 막기 위한 장치를 강화하는 것이 중요하다. 상속 증여세제 등의 강화나 기업경영의 투명성을 제고하기 위한 감시장치가 강화되어야 할 것이다. 특히 자유주의자가 강조하는 '정당한 권리의 원칙'으로서 '부정의의 시정'의 원칙이 보다 적극적으로 반영될 수 있어야 하며, 이러한 주장 자체가 시장 메커니즘을 옹호하는 진정한 자유주의 원칙에 입각하고 있다는 점이 강조되어야 할 것이다.

Xenon-129 NMR technique has been developed since 1980 as a new method for the characterization of microporous materials such as zeolites, activated carbons and alumina by using chemical shift and linewidth variations in $^{129}Xe$ NMR of adsorbed xenon gas. This NMR technique has been known to be very effective to probe the locational and the chemical changes of the supported metallic species as well as the physicochemical change of the support material. Recently, this method has been successfully applied for the characterization of amorphous materials such as activated carbons, silica and alumina. Basic principles, experimental techniques and recent applications of the $^{129}Xe$ NMR method for the study of heterogeneous catalysts are introduced in this paper.

According to the industrial restructuring in the late 1980's, most domestic mines have been shutdown or suspended in operation. The closed underground excavation caverns remain in their abandoned conditions, and they will potentially cause environmental hazards. To evaluate the feasibility of the utilization of the abandoned caverns, the foreign crises were studied. As a result, we proposed several possible examples including underground storage cavern fur food products, underground compressed air energy system(CAES), and underground repository (or incineration plant) of industrial wastes. Among them, the underground waste repositories are most probable to be seen in Korea in the near future. For this, the study in rock engineering aspects should be conducted, which will include the establishment of support system and safety measure of the abandoned underground excavation caverns.

The marine equipment industry in Korea has been growing along with shipbuilding industry since early 1980s. Major shipbuilding might be predicted to shift to China in the near future. Moreover, new paradigm of e-navigation is about to get geared in the real world, which was specifically noted by IMO (International Maritime Organization). In order to catch up with rapid changes in the environments, the industry sector should move fast, the public sector should setup proper measures, and the academic sector should spur the research and development of new technologies. In this paper, international marin equipment markets and standardization trends are presented along with several representative R&D activities.

Some analytical methods to analyze low-velocity impact force history of composite laminated structures used in aerospace vehicles are reviewed. A classical method used at initial research of low-velocity impact problem in 1980s was reviewed on its physical meaning, and the approximate method assuming the shape of impact force history as a sinusoidal wave was reviewed. A parametric study on contact constant and exponent in contact law was performed in order to analyze an effect on impact force history, and finally its was understood that impact force history could be analyzed accurately even though the linearized contact law was used. Also, in this paper it was shown that impact problem could be analyzed simply and easily using a commercial finite element code.
