Knowledge sharing by collective intelligence, and knowledge production/sharing by outer cooperation is also important for the company. Therefore, it is needed the next generation KMS(Knowledge Management System) designed and built which based on SNS. In my paper, the problems of KMS are analyzed and new KMS's requirements and paradigm changes are examined by analysis of investigation of existing KMS. KMS based on SNS is appropriate for the next generation KMS in consideration of new KMS's requirements, that is, collective intelligence, open innovation, and convergence with IT technology. So a building method of KMS based on SNS is presented by new next generation KMS's architecture, main design and knowledge-talk design.

차세대 에너지 절감 반도체로 각광을 받고 있는 GaN(Gallium Nitride) 전자소자의 연구개발 동향, 특히 전력증폭기용 GaN 기술동향에 관하여 기술하였다. GaN 전자소자는 와이드 밴드갭($E_g=3.4eV$)과 고온($700^{\circ}C$) 안정성 등 재료적인 특징으로 인하여 고출력 RF(Radio Frequency) 전력증폭기와 고전력 스위칭 소자로서 큰 장점을 갖는다. 본고에서는 차세대 GaN 전력소자의 주요 특성을 소개하고 미국, 유럽, 일본을 중심으로 한 대형 국책 연구 프로젝트 분석을 통한 GaN 전력소자 연구개발 방향 및 GaN 전력소자 시장과 주요 특허 현황을 살펴보았다. 또한 국내의 주요 연구개발 현황과 현재 수행 중이거나 완료된 연구개발 과제를 간략하게 언급하였다. 이러한 연구개발 현황분석을 통하여 GaN 기술의 중요성과 함께 국산화의 시급성을 강조하고자 한다.

From the cross Tongil$^2//IR833/IR1317$ glutinouse rice lines wx 126 were bred. Some of these lines were earlier than standard variety and later than glutinous check variety. Some of them yielded as much as standard variety and showed better resostances to blast, stripe deseases and smaller brown plant hopper than standard variety. It was sosscussed that, theough the vreedong procedure, following points were proved, 1)back-cross program in roce breeding was effocoent, 2)semi-dwarf plant type of "Tongil" has high yielding poteneoality and 3) the variety "Tongil" was a good for recurrent parent for back-cross program. back-cross program.

The introduction of 5G greatly reduced service traffic speed and capacity problems. In this communication environment, the market demand for cloud games is increasing, and cloud games are considered as a replacement for mobile games in the future. This study explains the changes in the game industry, and the characteristics and market status of cloud games. Next, this study suggests competitive advantage elements for cloud games market. We expect that this study could help make decisions related to policy support for the cloud game market and industry.

Financial transfers between parents and their adult children are a growing trend in Korean society. This study investigates the relation of household assets to intergenerational financial transfers among the middle-aged and focuses on the influences of various types of assets on financial transfers from the middle-aged to their older parents and adult children. The paper presents an analysis of data from the second wave of KReIS on the financial transfers provided by those aged 50-69 years to their parents and children. The results show that around one-fifth of the respondents reported providing financial resource transfers to their parents, and that about one-third of the respondents provided financial transfers to their children. In terms of the other direction of financial transfers, a small percentage of the respondents received financial transfers from their parents; otherwise more than half of the respondents reported receiving financial transfers from their children. The influences of various types of assets are statistically significant on financial transfers to parents, to adult children and from adult children. Specifically the size of financial assets is associated with a likelihood of providing financial resource to both parents and children.

For the purpose of finding out the effect of heat treatment on biological response and mutation rate, rice seeds were heat treated before and after gamma irradiation. 1. At a dose of 20 KR, pre-irradiation heat treatment showed reduced biological damage and increased mutation rate as compared with non-heat treatment. 2. Mutation frequency was increased in post-treatment of heat shock than in pre-irradiation heat treatment and non-heat treatment. 3. Pre-irradiation heat treatment at 6$0^{\circ}C$ for 30 minutes markedly reduced the biological damage and increased the mutation rate. 4. Mutation spectrum in heat treatment was different from non-treatment.

Soybean [Glycine max (L.) Merr.] seed size is a important yield component and is a primary consideration in the development of cultivars for specialty markets. Our objective was to examine the consistency of QTLs for seed size across generations. A 68-plant F$_{2} segregation population derived from a mating between Marcury (small seed) and PI 467.468 (large seed) was evaluated with RAPD markers. In the F$_{2} plant generation (i.e. F$_{3} seed), three markers, OPL09a, OPM)7a, and OPAC12 were significantly (P<0.01) associated with seed size QTLs. In the F$_{2} ; F$_{3} generation (i.e., F$_{4} seed), four markers, OPA092, OPG19, OPL09b, and OPP11 were significantly (P<0.01) associated with seed size QTLs. Just two markers, OPL09a, and OPL09b were significantly (P<0.05) associated with seed size QTLs in both generations. The consistency of QTLs across generations indicates that marker-assisted selection for seed size is possible in a soybean breeding program.
