Nawadays LNG has been beginning to take the place of petroleum as fuel all over the world and VLCC tankers of LNG will take the same sea routes that had been used by VLCC tankers of petroleum in the last pat of he 20th century. The transportation of LNG by a VLCC include more dangerous nature of sea peril than that of petroleum. We already know the dimensions of a disaster a LNG tanker could bring about in the case of the LNG tanker, Yuyo-Maru No. 10 in the Tokyo Bay of Japan in 1974. From the point of safety when we construct a LNG base or LNG pier in the base, the appropriate government authority and constructing company had better take sea pilots or some ships handling experts to participate in a prior consultation of the design of the project. A G/T 100,000 ton LNG base and pier were completed in November of 1996 in Inchon harbour in Korea and LNG VLCC tankers of G/T 100,000 ton class have been entering into the base ever since. This study was started and completed to comply with the requisition of the Sea Pilot Association of Inchon harbour in advance of the opening of the LNG base. As the entrance and exit channels leading to Inchon harbour were constructed in the years of 1930s, it was one of the most pressing works for Inchon sear pilots in 1996 to certify the method of safe passing maneuvering of a G/T 100,000 ton LNG tanker through the Pudo narrow channel prior to commercing actual piloting of the LNG VLCC tanker. The author made some mathematical models computing maneuvering of a vessel changing her course with her control surface through a narrow channel and computed maneuvering of a G/T 100,000 ton LNG tanker and also made maneuvering simulations of the vessel by a desk-top simulator. The results of computations and simulations are well coincided with each other in qualitative aspects to assure safe passing of the LNG VLCC.

The purpose of this study was to resolve the issues of inferior housing environment and the population decrease in rural community by improving the environment and attracting urban inhabitants. A simulation on the costs and the local programs was operated from a point of view that Pension Insurance House with Long-term Lease and a plan for the program in connection with local resources should be accompanied to attract urban inhabitants. The study was carried out through mainly documents analysis and specialists' opinions. The simulation results are as follows. Firstly, the pre-existing rural housing development projects have only emphasized the hardware, while underestimated the post-management with operating programs. The software should be underlined when Pension Insurance House is developed. Secondly, as a result of the simulation on construction expenditure and the operating and maintenance cost for 30 years, about 82.3 million Wons are necessary residential expenses for 15 years per unit. Thirdly, in case of MUJU County, it has made the most of its pre-existing institutions. It's medical institutions provide medical care system with health education, facilities related leisure and culture offer recreational programs and the local community center and its program of each town helps new habitants adopt to the rural life. Additionally, the employment project of a local welfare center allow people living in a rural community to continue their careers with their talents and interests through local class programs for a life worth living. Lastly, guide for getting information of rural life, local community gathering and preliminary education should be carried out to reduce expectant tenants' incompatibility and assist them settle down early. The community program expansion is also required at the local government level.

The SPICA (SPace Infrared Telescope for Cosmology & Astrophysics) project is a next-generation infrared space telescope optimized for mid- and far-infrared observation with a cryogenically cooled 3m-class telescope. It will achieve the high resolution as well as the unprecedented sensitivity from mid to far-infrared range. The FPC (Focal Plane Camera) is a Korean-led near-infrared instrument as an international collaboration. The FPC-S and FPC-G are responsible for the scientific observation in the near-infrared and the fine guiding, respectively. The FPC-G will significantly reduce the alignement and random pointing error through the observation of guiding stars in the focal plane. We analyzed the pointing requirement from the focal plane instruments. The feasibility study was performed to achieve the requirements. Here, we present the role of SPICA/FPC as a fine guiding camera.

The purpose of this study is to find out distributional principles of the shop-houses in residential district through physical composition of residential area. Through the research that are based on literature and field survey, it analysed the relation between physical composition of residential area and the shop-houses of selected four sites under similar urban condition where land readjustment project were held. The consequences of this study are summarized as follows; 1) A road that is not penetrating the inside a residential area is seemed to have low occupancy of shops comparing to other roads with similar hierarchy. And the shops functions as convenience facilities. It can be inferred from the statement above that even a road with higher hierarchy is not easy to form commercial area if without penetrating the residential area. 2) According to the size and the arranged method of Inner blocks of residential area towards major roads, distribution of shop-houses appear to be different. In other words, when shop-houses are located along the roads, the proportion of shop was higher than when located perpendicular to the roads. 3) When the number of average lots are little and the size of block is small, usually, street ratio and the number of corners gets higher, which eventually increases the number of shop-houses.

As an exploratory inquiry prior to developing a measure to assess Korean families with adolescents' family resilience, this study examined the construct validity of the family resilience measures that were developed in the U. S. Iowa Youth and Families Project(Conger & Elder, 1994): emotional support between spouses, problem solving style between spouses, and parenting behavior. The participants were 277 pairs of middle aged, middle class husbands and wives (554 individuals) who were the parents of first graders in middle schools in the metropolitan areas around Seoul. The results of exploratory and confirmatory factor analysis supported the construct validity, indicating that emotional support, problem solving style, and parenting behavior may be used as measures to assess Korean family resilience. However, further tests of convergent validity using various assessment methods and analytical procedures are needed to ensure the construct validity of family resilience measures.

한국의 애니메이션은 디지털 영상시대에 국가 전략 산업이란 이름 아래 명칭과 개념의 통일된 코드도 없이 지난 수년 동안 세계 최고 수준의 인프라가 형성되었다. 비교육적이고 경박한 문화에서 각광 받는 돈벌이로 현대의 시대성과 가장 밀착된 표현 형식으로 새롭게 평가 받고 있는 것이 디지털 애니메이션이다. 지난 30년 동안 대중 영상 매체에서 접한 애니메이션은 거의 전부 만화 영화였다. 결코, 예술로서 존중하지 않지만 늘 가까이 두고 기호품과 같은 만화 영화는 예술성과 문화성과는 별개로 자연스럽게 두터운 매니아 계층을 확보했다. 본 논문은 교육을 목적으로 하는 모바일 컨텐츠를 위한 애니메이션 알고리즘을 제안하고 이것을 이용하여, 가상 패류 박물관, 가상 화석 박물관을 설계 및 구현 하였고 1000여 가지의 동작표현 컨텐츠를 구축하였다. 사용자들은 상호 작용에 의해서 애니메이션 객체를 360도 회전시키거나 축소, 확대 등이 가능하다.

The combination of multiple antennas and multi-carrier code division multiple-access (MC-CDMA) is a strong candidate for the downlink of the next generation mobile communications. The study of such systems in scenarios that model real-life trans-missions is an additional step towards an optimized achievement. We consider a realistic MIMO channel with two or four transmit antennas and up to two receive antennas, and channel state information (CSI) mismatches. Depending on the mobile terminal (MT) class, its number of antennas or complexity allowed, different data-rates are proposed with turbo-coding and asymptotic spectral efficiencies from 1 to 4.5 bit/s/Hz, using three algorithms developed within the European IST-MATRICE project. These algorithms can be classified according to the degree of CSI at base-station (BS): i) Transmit space-frequency prefiltering based on constrained zero-forcing algorithm with complete CSI at BS; ii) transmit beamforming based on spatial correlation matrix estimation from partial CSI at BS; iii) orthogonal space-time block coding based on Alamouti scheme without CSI at BS. All presented schemes require a reasonable complexity at MT, and are compatible with a single-antenna receiver. A choice between these algorithms is proposed in order to significantly improve the performance of MC-CDMA and to cover the different environments considered for the next generation cellular systems. For beyond-3G, we propose prefiltering for indoor and pedestrian microcell environments, beamforming for suburban macrocells including high-speed train, and space-time coding for urban conditions with moderate to high speeds.

Objectives : The objective of this study was to examine the academic informationseeking behavior and demand of the oriental medical researcher and to create the base data for establishing a library environment providing a high-quality information service which would aid the activity of such researchers, Methods : We distributed a questionnaire to the one hundred professors of the college of oriental medicine on the method of acquisition of information data, the environment of the library belonging to the college, and the like. Results : $\circled1$ The main class using the academic information service of oriental medicine was revealed to be researchers having a career of 10 to 15 years who had a domestic doctorate in oriental medicine. $\circled2$ When accessing information, the primary information resource used was academic journals. $\circled3$ Of the data forms mentioned in the study, periodicals was used most in number of printed data; computer databases among non-printed data. $\circled4$ The purpose of using an information resource was for performing a research project. $\circled5$ The path of acquisition of information was usually through the materials in their possession. $\circled6$ The greatest difficulty in gathering information was first of all the lack of information owned by the library, and next a lack of time and insufficient knowledge of information search and use. $\circled7$ More than 90% of respondents on the necessity of an expert library answered as "necessary" or "certainly necessary", indicating that the foundation of an expert library is very urgent. Conclusions : This study is beneficial for researchers engaged in oriental medicine to activate the use of information and also it will form a base of data for researchers to establish an environment of expert library in oriental medicine.
