In this paper, we implemented a sign language communication system between korean and japanese using 3D model. Unitl now, we have developed the system through 2D image. The system, however, has some drawbacks base don the limitations of 2D model. Especially it is not comprehensive in the sign language gesture including forward or backward movements becasue it can only display a front view. Therefore, we employed a 3D model for the representation of sign language. The proposed communication system si implemented with windows 95 visual C++ 5.0 imported open inventor library on pentium 233 system. Experimented results show that the 3D system can solve the problems in 2D representation.

The purpose of the study is to examine the characteristics of the ideal housing for the modern family suggested by the Home Exposition (September, 1915) under the Japanese colonial rule in the macroscopic context of social change and the microscopic context of family. Through this research, we expect to have a partial understanding not only of changes in the outward appearance of traditional housing spaces during the civilization period and the early Japanese colonial rule when foreign cultures began to be introduced but also of families'residential lives and the patterns of change in people's consciousness of housing. Major conclusions from the current analysis are as follows. First, there were some changes in family paradigm induced through a home exhibition. Second, the most important factor for an ideal housing was that it must be the source of harmonic and healthy family life. Third, the importance of an appropriate space norm should be emphasized by providing the minimum size of each room. Fourth, the significance of the housing values of the economy, convenience, and hygiene should be emphasized for the ideal housing. Lastly, it was implied that for an ideal housing, the social and psychological aspects of housing must be satisfied along with the physical aspects. The limitation was that the model of ideal family housing presented in the Home Exposition cannot exclude the characteristics of the colonial perspectives in that it was followed by the model for the Japanese families.

A thermal time-based two-step phenological model was used to project flowering dates of Japanese cherry in South Korea from 1941 to 2100. The model consists of two sequential periods: the rest period described by chilling requirement and the forcing period described by heating requirement. Daily maximum and minimum temperature are used to calculate daily chill units until a pre-determined chilling requirement for rest release is met. After the projected rest release date, daily heat units (growing degree days) are accumulated until a pre-determined heating requirement for flowering is achieved. Model calculations using daily temperature data at 18 synoptic stations during 1955-2004 were compared with the observed blooming dates and resulted in 3.9 days mean absolute error, 5.1 days root mean squared error, and a correlation coefficient of 0.86. Considering that the phonology observation has never been fully standardized in Korea, this result seems reasonable. Gridded data sets of daily maximum and minimum temperature with a 270 m grid spacing were prepared for the climatological years 1941-1970 and 1971-2000 from observations at 56 synoptic stations by using a spatial interpolation scheme for correcting urban heat island effect as well as elevation effect. A 25km-resolution temperature data set covering the Korean Peninsula, prepared by the Meteorological Research Institute of Korea Meteorological Administration under the condition of Inter-governmental Panel on Climate Change-Special Report on Emission Scenarios A2, was converted to 270 m gridded data for the climatological years 2011-2040, 2041-2070 and 2071-2100. The model was run by the gridded daily maximum and minimum temperature data sets, each representing a climatological normal year for 1941-1970, 1971-2000, 2011-2040, 2041-2070, and 2071-2100. According to the model calculation, the spatially averaged flowering date for the 1971-2000 normal is shorter than that for 1941-1970 by 5.2 days. Compared with the current normal (1971-2000), flowering of Japanese cherry is expected to be earlier by 9, 21, and 29 days in the future normal years 2011-2040, 2041-2070, and 2071-2100, respectively. Southern coastal areas might experience springs with incomplete or even no Japanese cherry flowering caused by insufficient chilling for breaking bud dormancy.

Tree roots can enhance soil shear strength and slope stability. However, there has been a limited study about root reinforcement of major tree species in Korea because of some experimental difficulties. Thus, this study was conducted to analyze the performance of Japanese larch (Larix kaempferi) and Korean pine (Pinus koraiensis) which are two common plantation species in Korea. Profile wall method was used to measure the spatial distribution of root system and its diameter within 15 soil walls of Japanese larch stand and 13 soil walls of Korean pine stand in Taehwa University Forest, Seoul National University, Korea. Root tensile properties of each species were assessed in the laboratory, and root reinforcements were estimated by Wu model. The study observed that the number and cross-sectional area (CSA) of root in both species could tend to decrease with soil depth. Especially, CSA were well-fitted to exponential functions of soil depth. Mean root area ratios (RAR) were 0.03% and 0.10% for Japanese larch and Korean pine, respectively. Estimated root reinforcement from Wu model were, on the average, 4.04 kPa for Japanese larch and 12.26 kPa for Korean pine. Overall, it was concluded that root reinforcement increased the factor of safety (Fs) of slope for small-scale landslide as the result of two-dimensional (2-D) infinite slope stability analysis considering vegetation effects.

Ruminal degradation characteristics of dry matter (DM), neutral detergent fiber (NDF) and crude protein (CP) in fresh leaves of two Japanese native grasses (Zoysia japonica and Miscanthus sinensis) and one sown temperate grass (Dactylis glomerata) were investigated by an in sacco method in spring (mid-May), summer (mid-July) and autumn (mid-September). Japanese native grasses had higher NDF and lower CP concentrations than D. glomerata, and the CP concentration in native grasses decreased in autumn. Ruminal degradability of DM, NDF and CP was lower in native grasses than in D. glomerata (p<0.05) in all seasons. DM and NDF degradability decreased in summer for Z. japonica and D. glomerata, while it decreased in autumn for M. sinensis. CP degradability in Z. japonica was constant throughout the seasons, whereas that in M. sinensis greatly decreased in summer and autumn (p<0.05). It was concluded that Z. japonica could stably supply ruminally digestible nutrients for grazing animals in Japanese native pasture. However, the degradation characteristics of freshly chopped native grasses did not fit the exponential model of $D=a+b(1-e^{-ct})$ proposed by Ørskov and McDonald.

본 연구는 전통정원의 해외 보급 및 확산을 위한 기준점 마련과 기반 구축을 위한 기본연구로서 일본의 전통정원 보급 및 확산에 있어 초기 단계인 유럽과 미국에서 개최된 만국박람회 통한 조성내용과 파급효과를 규명하는데 목적을 두고 있다. 일본이 박람회를 처음 참가한 1867년부터 제2차 세계대전이 발발하는 1939년까지 일본 정원이 조성된 박람회를 대상으로 조성된 정원을 파악하고 박람회 기간 중 그리고 폐막 이후 일본정원의 파급효과를 조사 분석하였다. 연구의 결과를 종합하면 문화적 측면에서 명치정부의 첫 박람회 참여에 있어 독일인 바그너의 충고에 따라 문화와 공예를 박람회 주제로 선정하고 정원을 전통 건축물과 하나의 단위로 인식하면서 국가적 정책으로 대외 홍보 수단으로 삼았다. 그 결과 만국박람회 일본관에 대표적으로 조성된 강호시대 회유식 정원 양식과 다정은 유럽과 미국 내에서 일본정원의 대표적 양식으로 인식되었다. 정치적 측면으로는 미국인에게 일본 정원은 도입된 '이국적 미'이자 '문화유산'으로 인식되면서 일본에 대한 친근감을 높이고 반일감정을 없애려는 일본 제국정부의 목적을 달성하였고 전통정원을 통해 유구한 역사를 가진 일본사회를 이상적으로 표현하여 서구 열강과의 차별성을 도모, '전통'과 '자연'을 키워드로 '영원한 평온'이라는 국가 이미지를 구축하였다. 사회경제적으로는 박람회 이후 존치된 일본정원은 지속적인 일본정원의 모델 역할을 하였으며 박람회의 일본관을 조성하기 위하여 정원과 관련된 많은 전문가가 일본에서 미국과 유럽으로 간 후 현지 정착하며 일본 정원이 현지에 녹아드는 계기가 되었다.

A three-dimensional numerical model (POM) is implemented to examine coastal upwelling in the northern Japanese coastal region with the passage of Typhoon Oliwa in September 1997. Observed sea surface temperature (SST) decreased suddenly ranging from $-6\;to\;-7^{\circ}C$ in the coastal regions, and such a SST decrease state lasted for more than ten days after the typhoon passed. The model successfully reproduces the observation and gives a clear explanation, the sudden decrease of SST occurred in the process of coastal upwelling with Ekman dynamics. The model also describes the sea surface cooling in the open ocean with vertical velocity.
