  • This paper presents the research activities performed to date for the development of a supercritical pressure water-cooled reactor (SCWR) in Korea. The research areas include a conceptual design of an SCWR with an internal flow recirculation, a reactor core conceptual design, a heat transfer test with supercritical $CO_2$, an adaptation of an existing safety analysis code to the supercritical pressure condition, and an evaluation of candidate materials through a corrosion study. Methods to reduce the cladding temperature are introduced from two different perspectives, namely, thermal-hydraulics and core neutronics. Briefly described are the results of an experiment on the heat transfer at a supercritical pressure, an experiment that is essential for the analysis of the subchannels of fuel assemblies and the analysis of a system safety. An existing system code has been adapted to SCWR conditions, and the process of a first-hand validation is presented. Finally, the corrosion test results of the candidate materials for an SCWR are introduced.

  • This research was conducted to make suggestions for the promotion of research activities in the field of animal resources sciences, and we evaluated the research funding trend and the present status of research funding offered by KOSEF in this field. Comparative portion of the number of research projects and grants in this field to other fields has a tendency to be decreased year by year except recent few years. Researchers in this field have received more research funding from the group-based program than from the individual-based program. Also, they have received less money(per project) than did researchers in the fields of general agricultural sciences and other science and technology. Researchers in this field ranges from 43 to 51 years of age and showed 48 years of average age. It was found that researchers who has been funded in the field of animal resources sciences have showed tendency of publication of more articles to SCI journals in recent 5 years. The strong points of the animal resources of agricultural sciences field in South Korea include: lots of researchers, the establishment of research infra-structure, the excellence in research competitiveness and technology level. However, its weaknesses are: a lack of leadership in relevant societies and institutes, a predicted shortfall of researchers in the next generation and insufficient research productivity. The opportunities include: increasing the importance of the biotechnology industry, activating international cooperation researches and exploring the multitude of possible research areas to be studied. However, some concerns still exist, such as threats from developed countries for the government to open the agricultural market, the reduction of the number of full-time farms and intensification of needs for economic and social effects. The diverse actions and systems based upon the strongpoint, weakness, opportunity and threats above-mentioned are required to encourage research activities in the field of animal resources of agricultural sciences in Korea In addition, researchers in this fields would make an effort to keep pace with international society as well as domestic demands.

  • Global warming melts polar ice, changes ocean currents, creates variation of local climate, and inundates low-altitude regions resulting in disasters to mankind. Accordingly, developed countries including U.S.A. and U.K. spend great amounts of efforts and money to plan and manage research activities on polar ice which is regarded as a key indicator of climate change. The proposed research aims to provide basic information for chasing and monitoring the melting phenomena of polar ice through multiple GPS to enhance the GPS quality.

  • Recent research activities in cooperative communication focus on achieving energy efficiency and reliability. Relay selection strategy for cooperative communication improves the performance significantly. However, due to imbalance consumption of power, network might die earlier and more than 90% energy remains unused. In this paper, we provide a framework of an energy-efficient medium access control protocol that minimizes these problems and improves energy efficiency.

  • 대기침적은 대기중으로 방출된 오염물질의 이동과 그 영향을 조절하는 중요한 기작으로서, 현상론적인 형태에 따라 습성침적 및 건성침적으로 구분된다. 이러한 대기침적 현상은 수질의 악화, 건강 및 생태학적 악영향을 초래하는 중요한 요소로 작용할 뿐만 아니라, 최근 우리나라를 비롯한 동북아시아지역에서의 대기오염물질의 장거리 이동현상의 정확한 규명을 하기 위한 노력의 일환으로 그 관심이 모아지고 있다.(중략)

  • The basic factor that affect wear performance is the wear characteristics, which come from sliding friction between rubber compound and road. Thus, this study focused on friction and wear of rubber. This paper briefly explain some characteristics of friction and wear referring to the papers on wear of rubber that scholars researched on. Research activities to predict the performance of the rubber wear is also explained.
