This study is essential for advancing our knowledge about the interaction between long-range high-power lasers and energetic materials, with a particular emphasis on understanding the response of a 155-mm shell under various surface irradiations, taking into account external factors such as atmospheric disturbances. The analysis addresses known limitations in understanding the use of non-realistic targets and the negligence of ambient conditions. The model employs the three-dimensional level-set method, computer-aided design (CAD)-based target design, and a message-passing interface (MPI) parallelization scheme that enables rapid calculations of the complex chemical reactions of the irradiated high explosives. Important outcomes from interaction modeling include the accurate prediction of the initiation time of ignition, transient pressure, and temperature responses with the location of the initial hot spot within the shell, and the relative magnitude of noise with and without the presence of physical ambient disturbances. The initiation time of combustion was increased by approximately a factor of two with atmospheric disturbance considered, while slower heating of the target resulted in an average temperature rise of approximately 650 K and average pressure increase of approximately 1 GPa compared to the no ambient disturbance condition. The results provide an understanding of the interaction between the high-power laser and energetic target at a long distance in an atmospheric condition.

Energy environment has been changing rapidly such as the fluctuation of oil prices and the effect on UNFCCC. Oil price change affects Korea's economy heavily due to her poor natural resources and large dependence of consumed energy resources. Korea takes the 4th place of importing the crude oil and 9th place in $CO_2$ emissions with the 1st place of $CO_2$ emissions increasing rate. Considering the current statue of Korea including oil price change and UNFCCC, Korea will be expected to be the Annex I nation due to Korean energy environments and the quantity of $CO_2$ emission. Energy technology development is a crucial key to cope with Korea's national energy security and environments. In this study, we establish the framework, which allocates the relative weights of assessment criteria and sub-criteria, for assessing and selecting R&D programs of energy technologies strategically. We integrated fuzzy theory and analytic hierarchy process (AHP) approach since the fuzzy AHP approach reflects the vagueness of human thoughts and perception effectively as making pairwise comparisons of criteria and alternatives. The fundamental data of this research results will support R&D planning phase for policy-makers and the production of well focused R&D outcomes.

기업은 경쟁우위를 확보하고 지속적인 성장을 이끌기 위해 기술개발을 위한 R&D 투자 및 혁신활동에 집중해야 한다. 그러나, 기업의 이러한 활동은 언제나 성공하는 것이 아니며, 기술개발의 위험도가 높고 이익의 전용가능성이 낮거나 기업내부의 역량이나 자원이 부족할 경우, 기업의 혁신활동은 저해되기 쉽다. 이러한 상황에서 외부파트너와의 연구협력은 이러한 문제들을 해결할 수 있는 좋은 전략이라고 할 수 있다. 본 연구에서는 한국의 제조업체를 대상으로 각 기업이 기술혁신을 위해 연구협력을 선택할 때 어떤 요인들이 연구 협력결정에 영향을 미치는지를 분석하였다. 이를 위해서 과학기술정책연구원(STEPI)에서 수행한 기술혁신조사 데이터를 활용하였으며, 분석결과 기업의 규모가 클수록, 과거의 연구 협력경험이 많을수록, 하이테크 기업에 속한 기업일수록 연구협력을 통해 제품혁신을 수행하는 것으로 나타났으며, 혁신실패의 위험성, 자금조달의 어려움, 조직내부의 역량부족, 외부환경요인 등과 같은 혁신활동저해요소들은 제품혁신활동 수행시 외부와의 연구협력에 영향을 미치지 못하는 것으로 나타났다.

To achieve the "low carbon green growth" vision, the first step is securing core technologies. Therefore, S&T policy direction for green technology development is urgently needed. As of 2008, investment in green technology (GT) development hovered around 10% of the government's total R&D budget. Thus, the Korean government developed a plan to increase that percentage to 15%, by 2013. To develop reasonable investment strategies for green technology development, targeted strategies that reflect technology and market changes by green technology area are needed. However, the overall planning and coordination of national GT development is currently split among, approximately, 10 government ministries. To establish an efficient green technology development system, the so-called "Green Technology R&D Council" should be launched in collaboration with the Presidential Committee on Green Growth and the National Science and Technology Council. Furthermore, to build a solid foundation for commercializing the outcomes of GT development projects and promote GT transfer, the government should undertake two initiatives. First, the government should reinforce GT R&D performance management, by establishing a GT R&D performance management and evaluation system. Second, the government should implement the "customized packaged support for promoting green technology business rights and commercialization" and present "e-marketplace for market-oriented green technologies". Creating a pan-ministerial policy for GT development policy would necessitate restructuring the HR(Human Resources) development system, which is currently separated by technology area. Based upon mid/long-term HR supply and demand forecasts, the government should design differentiated HR development projects, continuously evaluate those projects, and reflect the evaluation results in future policy development. Finally, to create new GT-related industries, the "Green TCS (Testing, Certification, and Standards) System" needs to be implemented. For objective evaluation and diffusion of R&D results by green technology area, a common standardization plan for testing, analysis, and measurement, like the "Green TCS", should be developed and integrated.

In April 2001, many Japanese national institutes were reorganized as Independent Administrative Institutions (IAI) based on the General Act for Independent Administrative Institutions and the act for each institution. Under the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the National Institute for Materials Science (NIMS) was established by the merger of the National Research Institute for Metals (NRIM) and the National Institute for Research in Inorganic Materials (NIRIM). One of the biggest changes was the expansion of autonomous administration. The nanotechnology and material R&D field was prioritized in the 2nd (2001-2005) and the 3rd (2006-2010) Science and Technology Basic Plans; subsequently, NIMS was assigned to take the initiative in nanotechnology as well as materials science. NIMS has proactively expanded research fields through the introduction of researchers from polymers, electronics, and biotechnology as well as member institutes of the World Materials Research Institute Forum (WMRIF). Globalization has been promoted through programs that include the International Center for Young Scientists (ICYS) and the International Center for Materials Nanoarchitectonics (MANA). The 4th Science and Technology Basic Plan (2011-2015) emphasizes outcomes-recovery and rebirth from the disaster, green innovation, and life innovation. The Midterm Plan for NIMS also follows it. R&D collaboration by multi-partners (that include industry, university, and GRI) should be strategically promoted where GRI are especially required to play a hub function for innovative R&D and open innovation. NIMS highlights are Tsukuba Innovation Arena (TIA) and the Nanotechnology Platform Project. On January 20, 2012, a new organization was decided on by the Japanese Government where several IAI from different science and technology areas will be merged to realize more effective R&D as well as administrative cost reductions. NIMS is also supposed to be merged with 4 other R&D IAI under MEXT by the end of 2013.

그동안 과학기술정책은 연구개발 투자규모를 늘여서 논문이나 특허 같은 연구성과물을 창출해내는데 집중되어 왔다. 하지만, 과학기술의 경제적 역할이 강조되고 창조경제가 부각되면서, 기술사업화에 대한 정책적 관심이 높아지고 있다. 정부가 추진하는 기술사업화란 공공연구기관의 연구성과물이 민간 기업에서 상용화될 수 있도록 지원하는 일련의 혁신과정을 일컫는데, 조직 외부로의 지식(공공기술)의 흐름과 확산을 수반한다는 점에서 유출-개방형 기술혁신과 그 맥을 같이한다고 볼 수 있다. 본고는 이러한 견지에서, 주요 경제부처(미래창조과학부, 산업통상자원부, 중소기업청)의 기술사업화 예산사업에 대한 분석을 하였다. 이를 통해 현재의 기술사업화 정책현황을 진단하고 향후 정책과제를 도출하였다. 본고는 기술사업화 예산사업이 (1) 부처별로 특화되고, (2) 기술이전에 대한 지원을 강화하며, (3) 통합적 연계를 통해 지원 스펙트럼을 확대하고, (4) 엑셀러레이터 같은 민간 전문가 그룹을 육성하는 방향으로 추진될 것을 정책제언으로 제시하였다.

The purpose of this case study is to understand the sustainability practices of knowledge transfer process at the Malaysian government-industry-academia consortium. At this stage in the research, the R&D consortium is defined as an established entity by two or more organizations that pool resources and shared decision making for cooperative research and development activities. In attempts to understand the formation, outcomes and sustainability of the sustainable knowledge transfer process, this paper conducted a systematic literature review based on Gough, Oliver and Thomas systematic reviews protocol. From the review, the data were enriched and enhanced with a better understanding of sustainable knowledge transfer process. The systematic review resulted in identifying six factors including internal and external perspectives. However, key sustainability factors are not only directly influencing KTP, and the consortium, but are also mediated by other organisational variables.

In cases of severe alveolar bone atrophy in the posterior maxillary area, which has only a thin sinus floor, the autogenous tooth bone graft block (ABTB) was used to wrap the implant to enhance its primary stability and osseointegration in the sinus. These cases with four years of clinical follow-up demonstrate the applicability of the ABTB in maxillary sinus membrane elevation to improve the outcomes of implant placement.
