Representing 3-D objects with LOD requires a set of appropriate meshes according to the detail requirements. We have developed a system for improved geometry model data transmission and management by having only the wavelet coefficienets of the model corresponding to the detail levels, instead of generation all the meshes through wavelet transformation, when generating multiresolution meshes.

최근 모바일 기술의 발달로 GIS분야에서도 모바일 기술을 이용한 다양한 서비스가 이루어지고 있다. 수치데이터나 이미지데이터를 기반으로 하는 모바일GIS는 최근에 XML기반의 표준화 된 GML데이터의 사용을 연구 하고 있다. 하지만 모바일 환경에서의 데이터 처리는 유선환경에서 보다 좀더 많은 데이터 처리비용을 요구 하고 있다. 본 논문에서는 모바일 GIS에서 표준화 된 GML을 사용 할 때 무선영역에서의 변환을 통해 좀더 경제적인 무선데이터 처리를 제안하고자 한다. 아울러 제안하는 데이터의 효율성의 평가하기 위해 데이터의 양을 측정하였다.

Wheat is one of the world's top three crops and is an important staple crop, accounting for 20% of the nutrient calories consumed by the world's population. However, due to its complex heterogeneous hexaploid chromosomes and vast genome of approximately 16 Gb, compared to those of other crops, molecular biology and biotechnology studies on wheat are lacking. In recent years, wheat genome analysis has been performed using the latest next-generation sequencing technology so that useful genes can be easily obtained, and wheat biotechnology research is accelerating in various fields. In this review, wheat transformation, an indispensable technique for developing new functional biotech wheat by revealing the function of wheat genes, is described in detail. In addition, the latest research results for overcoming plant diseases, abiotic stresses, and wheat-related diseases that are difficult to solve by classical breeding through wheat transformation and biotechnology are described.

Recently, with the development of wireless communications and GIS, interest about mobile computing is rising. In this case, the GIS needs to be placed in a constricted environment than the environment of server computing. For this reason large amounts of spatial data must be compressed into the mobile device. The compression technique of the spatial data is difficult and must be processed in the correct order because the size of the data is unpredictable. Therefore, in this paper, the cell-based compression technique of the spatial data for mobile GIS is presented. This paper includes the process of transformation of spatial data from a certain server to a mobile device by cell-based compression technique. In this paper, the cell-based compression technique of the spatial data has been proven practically efficient.

Recombinant Saccharomyces cerevisiae strains harboring various copy numbers of hirudin gene were developed to study dependency of hirudin expression level on its gene copy number. A linear relationship between the copy number of hirudin expression cassette and hirudin expression level was observed up to 10 copies. A double <5-integration vector truncated wi 디 1 the unnecessary bacterial genes before yeast transformation showed a four-fold increase in transformation efficiency and a 1.3-fold enhancement in hirudin expression level compared with a single <5 system. Gratuitous hirudin expression strain was developed by disrupting the GALl gene of S. cerevisiae. Glucose that was fed in a limited manner effectively supported cell growth and hi겨din expression by the gratuitous strain. Effects of methanol concentrations on hirudin production in recombinant Hansenula polymorpha were investigated in continuous and fed-batch cultures. At a steady-state of continuous culture, an optimum methanol concentration of 1.7 g/L was determined at a dilution rate of 0.18 $h^{-1}$ with 1.8 mg/L ${\cdot}$ h hirudin productivity.
