The aim of this project is to develop an adaptive and collective National Marine Biotechnology Plan for the next decade(2014~2023) which is able to reflect current and future changing environment. This effective strategy targets to foster marine-derived active bio-materials, marine bioenergy production technology and many promising technologies in order to promote marine biotechnology industry as a next-generation growth engine. Marine biotechnology industry based on R&D activities since 1980 has been growing as an emerging industry. This new field enables to secure exclusive patent rights and to find new potential bio-active materials from the ocean that requires long-term aggressive R&D investments. The current policy direction is to raise appropriate level of R&D investment because the current Korea's national marine biotechnology R&D fund ratio is less than 2% of the total national biotechnology R&D budget. The result shows three major strategies. First, it recommended a research implementation system and supporting policy that includes establishment of open innovation framework for the 'Industry-Academia-Research Institute Collaborations', strategic research planning and enhanced policy making process. Second, it derived state-of-the-art or new technology in many areas. Third, it formulated more detailed execution plans for successful R&D support and set up performance indicator system in related R&D program.

해양은 인류가 앞으로 풀어야 할 숙명적인 문제인 식량문제, 자원문제, 환경문제를 해결할 수 있는 마지막 보루이다. 이러한 점을 감안하여 국내 산 학 연 전문가가 참여하여 추진한 $\ulcorner$해앙과학기술(MT) 개발 계획$\lrcorner$ 이 2004년 7월 28일 대통령을 위원장으로 하는 국가과학기술위원회 심의에 통과됨으로써 우리나라에서도 본격적으로 MT 개발을 추진할 기반을 마련하게 되었다. 또한, 2005년 6월부터 $\ulcorner$MT개발기획$\lrcorner$을 효율적으로 추진하기 위한 후속조치로 해양과학기술 로드맵(MTRM) 수립을 추진하여 2005년 12월에 완료하였다. 본 연구에서는 MT의 국내외 기술개발동향과 현재 직면한 현안문제 및 MTRM수립 결과를 고찰하고, MT R&D 전문기관 설치 운영 및 예산확보 등 MT 활성화 방안을 제시하였다. Marine Technology is the last hope of mankind for resolving predestined issues of food, resources, and environmental problems. facing and realizing this great challenge, domestic industrial, academic and research institutional experts participated in formulating the Marine Technology development plan, and the national science and technology committee chaired by the president passed this important plan thus setting the foundation for activating and promoting MT development. A project to develop Marine Technology Road Map(MTRM) has been carried out since June of 2005 for effective execution of the plan 1his paper reviewed current issues of MT and contents of MTRM, and proposed alternative measures for MT activation and promotion such as the establishment of special institutes for managing MT research and development and the fund raising for MT budget.
고상확산접합된 Haynes230의 인장성질에 미치는 접합조건의 영향

This study investigated the effect of bonding temperature and holding time on microstructures and mechanical properties of diffusion bonded joint of Haynes230. The diffusion bonds were performed at the temperature of 950, 1050, and $1150^{\circ}C$ for holding times of 30, 60, 120 and 240 minutes at a pressure of 4MPa under high vacuum condition. The amount of non-bonded area and void observed in the bonded interface decreased with increasing bonding temperature and holding time. Cr-rich precipitates at the linear interface region restrained grain migration at $950^{\circ}C$ and $1050^{\circ}C$. However, the grain migration was observed in spite of short holding time due to the dissolution of precipitates to base metal in the interface region at $1150^{\circ}C$. Three types of the fracture surface were observed after tensile test. The region where the coalesce and migration of grain occurred much showed high fracture load because of base metal fracture whereas the region where those did less due to the precipitates demonstrated low fracture load because of interface fracture. The expected fracture load could be derived with the value of fracture area of base metal ($A_{BF}$) and interface ($A_{IF}$), $Load=201A_{BF}+153A_{IF}$. Based on this equation, strength of base metal and interface fracture were calculated as 201MPa and 153MPa, respectively.
셀룰러 네트워크 환경에서 D2D 통신을 위한 스펙트럼 센싱 기반 자원 할당 기법
강길모(Gil-Mo Kang),신오순(Oh-Soon Shin) 한국통신학회 2013 韓國通信學會論文誌 Vol.38 No.10(통신이론)
셀룰러 네트워크에서 D2D 통신을 지원하기 위해서는 기존의 셀룰러 통신과 D2D 통신이 셀룰러 자원을 공유하므로 주파수 효율성과 간섭에 대한 고려가 반드시 필요하다. 따라서 D2D 통신을 위한 자원할당은 셀룰러 통신과의 간섭을 최소화하면서 동시에 주파수 재사용에 따른 스펙트럼 이용 효율을 최대화하는 것이 바람직하다. 본 논문에서는 D2D 단말과 기지국이 상호 협력적인 방법으로 D2D 자원을 할당하는 기법을 제안한다. D2D 단말은 스펙트럼 센싱을 통해 셀룰러 단말과 다른 D2D 단말로부터 오는 간섭을 인지하여 최적의 셀룰러 자원을 선택하여 기지국에 보고한다. 기지국은 해당 셀룰러 단말과 D2D 단말이 동일한 자원을 공유하도록 자원할당을 함으로써 간섭의 영향을 최소화한다. 3GPP LTE (Long Term Evolution)-Advanced 환경에서 모의실험을 통해 제안한 자원할당 기법의 성능을 검증한다. For D2D communications underlaying cellular networks, it is essential to consider the mutual interference between the existing cellular communications and D2D communications as well as the spectral efficiency, as they need to share the same frequency. Accordingly, a resource allocation scheme should be designed in such a way that minimizes the mutual interference and maximizes the spectrum utilization efficiency at the same time. In this paper, we propose a resource allocation scheme based on cooperation of the base station and D2D terminals. Specifically, a D2D terminal senses the cellular spectrum to recognize the interference condition, chooses the best cellular resource, and reports the information to the base station. The base station allocates D2D resource such that the corresponding D2D link and cellular link share the same resource. The performance of the proposed resource allocation scheme is ated through compu under 3GPP LTE-Advanced scenarios.
