This paper examines university patenting activities as a commercialization of academic research. It shows how a number of university patents increase exponentially and how that can be, especially in terms of role of the state. In the late 1990, the Korean government supports the new vision of 'technological innovation' in establishing a science and technological policy and begins to perceive the importance of university R&D to overcome the economic crisis. Thus, an administrative, financial, and legal systems which support the university R&D are organized and the governmental grants for R&D increase exponentially, especially in promising new technologies(6T). Also, an institution for managing intellectual property rights is established in university. Universities assess professor's performance in terms of patent and license to encourage patenting activities. Thus the number of patents and its productivity increase exponentially. But the increase in patents takes place only to a dozen of universities, this means that a Matthew effect does work.

1990년대까지 정부출연연구기관은 우리나라의 과학기술을 선도하는 연구개발의 한 주체로서 중요한 역할을 담당해 왔으나, 최근 급속히 변화되고 있는 경제 사회 및 기술적 환경 속에서 정부출연연구기관의 역할 및 위상에 대한 문제점들이 선행연구에서 지적되고 있다. 현재 정부출연연구기관은 각자의 역할 및 위상에 따라 다양한 형태로 정부R&D 과제들을 수행하고 있는데, 이 중 특정 기술분야 및 기술단계에 집중된 과제를 수행하는 출연연구기관이 있는 반면, 다양한 기술분야 및 기술단계의 과제를 수행하는 출연연구기관도 있다. 한 분야에 집중된 과제의 수행은 해당 기술분야의 노하우(know-how), 지식, 기술을 집중적으로 축적하고 해당 분야에 대한 전문성을 제고함으로써 높은 논문성과를 이끌어 낼 수 있을 것이다. 그러나 한 기관에서 다양한 분야의 과제를 수행하는 것 또한 여러 분야의 지식이나 기술을 획득 보유하게 함으로써 다양하고 창의적인 연구를 가능하게 하고, 지식 및 기술 간 융합에 따른 시너지 효과를 통해 높은 논문성과를 도출하는데 기여할 수 있을 것이다. 이처럼 판단하는 시각에 따라 기관이 수행하는 과제의 집중화 정도가 논문성과에 미치는 영향이 상반되게 해석되는 상황에서, 본 연구를 통해 실제 우리나라의 출연연구기관의 경우 그 영향이 어떻게 나타나는지 실증분석을 통해 살펴보고자 한다. 이에 따라 논문을 주요 연구성과로 하는 기초기술연구회 소속 정부출연연구기관을 대상으로 정부출연연구기관이 수행하는 과제특성의 집중화 정도에 따라 집단을 분류하고, 이들 집단 간의 논문성과 차이를 비교 분석함으로써, 출연연구기관 특성에 따른 차별화된 정책 운영에 대한 시사점을 제시하고자 한다.

Previous researches on technological innovation have several limitations such as lack of general mechanism for technological innovation(inputs, throughputs and outputs of technological innovation), large company oriented studies, and ignoring importance of technology management capabilities. So, this study suggested a new model using resource-based theory and system theory, and empirically applied that to SMEs. Structural equation model analysis by using 223 SMEs in Daegu region provided a support for most of hypotheses. Research results showed that all of factors on technological innovation were significantly and positively related with each other: inputs(R&D leadership, innovation strategy, R&D investment, R&D human resource management, external network), throughputs(portfolio management, project management, technology commercialization) and output(technological innovation). In case of technological innovation inputs, R&D leadership influenced on innovation strategy positively and significantly. And R&D leadership and innovation strategy had positive and significant effects on R&D investment, R&D human resource management and external network. R&D human resource management and external network exerted positive and significant influences on technological innovation throughputs such as portfolio management and project management. But R&D investment did not significant impacts on technological innovation throughputs. Among technological innovation throughputs, both portfolio management and project management had positive and significant effect on technology commercialization. In addition, technology commercialization acted positively and significantly technological innovation output. This study suggests necessary of efforts to implement innovation strategy and manage R&D human resource effectively based on CEO's innovativeness and entrepreneurship. Also, if SMEs want to develop technology and commercialize it, they have to cooperate with external technology resources and informations. Research results revealed that proper level of R&D investment, internal and external communication, information sharing, and learning and cooperative culture were very important for improvement of technological innovation performance in SMEs. Especially, this research suggested that if SMEs manage technological innovation process effectively based on resource-based and system approaches, then they can overcome their resource limitations and gain high technological innovation performance. Also, useful policy support for technological innovation of central or regional government by this research model is important factor for SMEs' technological innovation performance.

To meet $CO_2$ emission regulation, this study describes the present state of $CO_2$ reduction technology and the effect of the regulation on power industry. In Japan, R&D investment is actively continuing through a long-term R&D project, along with trying to meet the reduction demand by the ways of energy saving and abroad business. EU has made a lot of investments in increasing the efficiency of power generation and developing alternative energy sources. The US is making provision of the portion of reduction by using energy saving program and emission trading, and the current DOE-driven program is addressing the development of cost-effective power systems. In the country, the research to reduce $CO_2$ emission has been mainly driven by the government and research institute supported by the government. Meanwhile, if the reduction obligation imposed on Portugal which is the least strict condition will be enforced in Korea, it is likely that about 50 running power plants should be stopped or shut down after 2015, in spite of voluntary reduction efforts such as conversion to clean fuels, etc. according to the government's long-term electric power need and supply plan.

In recent years, the occurrence of abnormal weather has increased rapidly, increasing the frequency of torrential rain. As a result, stable water resource management is difficult, and human and material damage is increasing. Various measures are being established to reduce damage caused by torrential rains, but small-scale mountain catchments are relatively difficult to manage due to lack of basic plan. In this study, the risk of flooding was evaluated using the rainfall-flow model in the Yeonhwa-dong catchment national park among national parks in Korea. The Yeonhwa-dong catchment of Mt. Sobaeksan was simulated to cause flooding when rainfall of more than 50 years occurred, and it was confirmed that there was a high risk of water resource structures, safety facilities, and trails.

This study was carried out to investigate aroma patterns of Hanwoo (Korean cattle) beef using electronic nose during refrigerated storage, and to compare these results with chemical quality (pH, TBARS). The M. longissimus muscle from Hanwoo carcasses after 24 hrs postmortem was obtained and stored at 5${\pm}$1$^{\circ}C$ for 7 days. Sensitivity (dR/RO) values among electronic nose data were changed differently during refrigerated storage, and showed significant difference on the 7th day of storage (p<0.01). The dR/RO from SY/G, SY/AA, SY/Gh, SY/gCTl, SY/gCT decreased but those from SY/LG, T30/1, P10/1, P10/2, P40/1, T70/2, PA2 increased during storage for 7 days. Mapping these data using PCA (principal component analysis) showed that the 1st day data were present in the middle of the right side, the 3rd day data were present in bottom part of this area and the 7th day data spread out more widely on the left side. In case of DFA (discriminant factor analysis), the flock clustered round and located in different side clearly comparing with PCA plot. In analysis of correlation coefficients among electronic nose data and chemical quality data, there was significant correlation among sensor data (p<0.001). But pH and TBARS were not significantly correlated with electronic nose data. Consequently, PCA and DFA plot by electronic nose data showed difference during refrigerated storage and there were significant correlations among sensors. Therefore it will be possible to detect separate aroma patterns of Hanwoo beef using electronic nose.

The alternation of extracellular matrix (ECM) protein in aging process is associated with symptoms such as wrinkling and loss of elasticity in skin. Now, the major target proteins for anti-aging have been metalloproteases and the structural proteins such as collagen and elastin. Recently, the interaction of cell and ECM proteins (collagen, fibrillin, and fibronectin) is reported to have an important role in survival, proliferation and tissue reconstruction. Fibronectin is a matrix adhesion protein which binds to collagen and integrin and degraded by serine proteases. It has been reported that fragments of fibronectin (Fn-fr's) were involved in matrix metalloproteases (MMPs) expression in osteoblast. But, the role of Fn-fr's in human skin and in skin cells has not been reported yet. Therefore, we investigated the differences of fibronectin fragmentation pattern between young and aged human skin, and demonstrated that the fragmentation of fibronectins is significantly increased in aged human skin. Also, treatment of Fn-fr's (70, 45 kDa) increased MMP-1 expression and MMP-2 activity in human dermal fibroblasts. Our results suggest that Fn-fr's as a potential new factor to accelerate skin aging.

We investigated the temperature uniformity in an anode-supported solid oxide fuel cell, using the open source computational fluid dynamics (CFD) toolbox, OpenFOAM. Numerical simulation was performed in three different flow paths, i.e., co-flow, counter-flow, and cross-flow paths. Gas flow in a porous electrode was calculated using effective diffusivity while considering the effect of interconnect rib. A lumped internal resistance model derived from a semi-empirical correlation was implemented for the calculation of electrochemical reaction. The result showed that the counter-flow path displayed the most uniform temperature distribution.
