On the stage of transition from highly centralized government to local self-government in Korea, administrating practice characteristics of the directors of Health Centers is essentially required to be found. This study was conducted in order to find the administration patte군 of the directors of Health Centers in Korea and their opinion on the environment of health administration including personnel management regime for them. The materials were collected from 149 directors of Health Centers with a structured questionaire by mailing. The major findings of this study were as follows. 1. About two-thirds of the directors(69.1%) make plan through the consensus between public service perosonnel in programme department and them in budgt control department. And 75.0% of the directors maintain the planed by the predecessor. 2. More than two-thirds of the directors (71.1%) take subordinates opinion into consideration in case of the programmes facing objections. 3. When the directors face obstacles in pursuing health programmes they usually consult other public service personnel than inhabitants. 4. Only 10.8% of the directors were satisfied with the support of the Ministry of Internal Affairs for health administration while more than half of them were satisfied with the support of health institution in higher level. 5. The directors evaluated the job attitude of the public service personnel in low level as more favorable than that of there higher level public service personnel who work for central government. 6. Only 18.1% of the idrectors were satisfied with their saley. And more than half of them expect the promotion of their position. On the ground of this result the administration attitude of the directors of Health Centers would be evaluated as improved and as more positive than that of other public service personnel in health authorities.

최근 동해상의 일본 서해안을 포함한 태평양 연안의 지진대에서 큰 규모의 해저지진에 의한 지진해일이 자주 발생하고 있다. 지진해일은 수심이 깊은 대양에서 파고가 대략 수 m인데 반해 파장은 수십에서 수백 km에 달하는 장파로서, 선단파는 수심에 비례하여 매우 빠르게 이동할 수 있다. 따라서 지진해일은 인접국가 뿐만 아니라 발생지역으로부터 매우 먼 지역까지 전파하여 해안에 심각한 범람으로 인한 인명 및 재산피해를 일으킨다. 이러한 지진해일의 피해를 효율적으로 저감하는 방법은 해안지역을 따라 지진해일 재해정보도를 제작하고, 지역주민들에게 이를 배포하여 사전에 위험성을 알리고 지진해일 발생시 피해를 최소화할 수 있도록 대비하는 일이다. 지진해일 재해정보도는 과거의 지진해일 피해조사 결과와 계획된 시나리오를 바탕으로 만들어져야 하며, 실제 지진해일이 급습할 경우 주민들의 대피계획을 만드는 데 유용하게 사용된다.

The purpose of this study is to figure out the structural characteristics of urban plant community and suggest restoration model of Quercus mongolica in the case of Korean national Capital Region. The investigation areas were selected from urban area of Mt. Nam at Chung-Gu, suburban areas of Mt. Bong at Eunpyoung-GU, Mt. Sungju at Buchon City and non-urban areas of Mt. Suri at Kunpu City and Mt. Chonma t namyangju-City. After the main study field had been classified into the evaluation of the ecological characteristics and the modeling of the vegetation. We analyzed to evaluate the ecological characteristics of the forest structure -- successional stage, naturalness, multi-layer structure of the forest and species diversity, and the plant community structures. We have proposed vegetation restoration model based on the selection of proper plants, the number of individuals, diameter short area of breast height, the shortest distance between plants in non-urban area. As for successional stage, It was judged that the ecological succession may not be followed like the present stage of the surveyed areas in urban, suburban and non-ruban areas. As for the retention of naturalness and multi-layer structures of vegetation, In Quercus mongolica community, Robinia pseudo-acacia and Ailanthus altissima occurred in each layers at Mt. Nam, Mt. Bong and Mt. Sungju, and Eupatorium rugosum occurred in herbaceous layer at Mt. Nam. Consequently, the ecological restoration plan following the structure of the vegetation in Mt. Chonma seemed to be advisable in Q. mongolica community, there were less number of species and individuals in urban areas than those of non-urban areas. Planting of trees following the simulated native plant community of non-urban areas seemed to be required to promote the plants in urban areas. Considering the number of individuals up to three layers in each 400$m^2$ area, it was composed of twenty nine in canopy layer, forth nine in understory layer, 367 in shrub layer and 33.7% herbaceous ground cover in the Q.mongolica community. The suggested restoration model in this study is nan applicable model for the introduction in the cities, and this study shows that continuous experiments and field investigation on this model should be performed in the future.

Superconducting fault current limiter (SFCL) is an power device of a novel concept. While SFCLs generate no ohmic loss during the operation carrying normal currents, they can limit fault currents very fast making large impedance by their quench characteristics. In 2006, KEPCO has developed a distribution class hybrid type SFCL by a collaborative research project with LS industrial systems. The SFCL has merits in practical and economical points of view. In the SFCL, the superconductor just plays a role of a fault detector and the current limiting is completed by the other current limiting element made of normal metals throu호 the line commutation. As a result, the required amounts of superconductors can be reduced considerably. Consequently, the hybrid SFCL can be fabricated with small size and cost, maintaining perfect current limiting performance. Currently, KEPCO is carrying out a research project at Gochang power test center for the purpose of the verification test of the 22.9 kV/ 630 A class SFCL for the practical application in real grid. Through the project, a long term operational test and fault current test will be done. In this paper, the back ground of development and installation of the SFCL will be explained and the operation plan of the SFCL for the verification test is also introduced.

China, as a developing country with a great number of population and relatively less energy resources, reasonably emphasizes the nuclear energy utilization development. For the long term sustainable energy supply, as for nuclear application the basic strategy of PWR-FBR-Fusion has been settled and envisaged. Due to the economy and experience reasons the nuclear power and technology development with a moderate style are kept in China up to now. In China mainland apart from two NPPs with the total capacity of 2.1 GWe in operation, four NPPs are under construction and two NPPs are planned for the Tenth Five Year Plan(2001-2005). Also another one or two NPPs are still in discussion. It could be foreseen that the total nuclear power capacity will reach 8.5GWe before the year 2005 and 14-15 GWe before 2010 respectively. As the first step for the Chinese fast reactor engineering development the 65MWt China Experimental Fast Reactor(CEFR) is under construction. The main components of primary, secondary and tertiary circuits and of fuel handling system have been ordered. The reactor building under construction has reached the top namely 57m above the ground. More than one hundred components and shielding doors have been installed. It is planned that the construction of reactor building with about 40,000$m^2$ floor surface will be completed in the end of the year 2002 and envisaged that the first criticality of the CEFR will be in the end of 2005. The second step of the Chinese fast reactor engineering development is a 300MWe Prototype Fast Breeder Reactor which is only under consideration up to now. Some important technical selections have been settled, but its design has not yet started.
