This study analyzed the factors influencing the technology transfer of Government-Funded Research Institutes from the perspective of resource-based view. In particular, we analyzed the effects of research resources, research capacity, and research results diffusion variables on technology transfer performance. The research resource variables affect the primary output of R&D (patents, research papers) but direct effect on the technology transfer performance was very weak. Among the research competency variables, patent-related variables such as patent registration, patent holdings have a significant effect on the technology transfer performance. However, the research papers have a negative effect on the technology transfer performance. The research results diffusion variables such as TLO organization and TLO budget may partly have a positive impact on technology transfer, but the statistical significance is not clear.

In Seoul, the subway system has been in use since 1974 and is the most frequently used travel mode accounting for approximately 40% of passenger journeys in 2015. As such the subway system is widely adopted by people and therefore, can have great impacts on their everyday life. However, it is easily noted that transit resources are not distributed spatially uniform, in other words, not all parts of the city gain the same benefits from their networks. This study aims to examine the inequity of spatial distribution of subway networks based on accessibility. Accessibility of subway networks are calculated based on the time-distance between stations and then equity is measured using the Gini index. Resulted map of subway accessibility shows that the benefits are not evenly distributed in Seoul with a pattern of highly accessible core - less accessible periphery areas. Also the subway accessibility network has fairer distribution against the employees' distribution rather than the distribution of general population or possibly transit dependent groups.

The Internet of Things (IoT) era, in which all items used in daily life are equipped with a network connection function, and they are closely linked to increase the convenience of life and work, has opened wide. Robots also need to develop according to the IoT environment. A use of new type of evolved fuzzy machine (EFM) for generating legged robot trajectory in IoT enviornmentms is discussed in this paper. Fuzzy system has been widely used for describing nonlinear systems. In fuzzy system, determination of antecedent and consequent structures of fuzzy model has been one of the most important problems. EFM is described which carries out evolving antecedent and consequent structure of fuzzy system for legged robot. To generate the robot trajectory, parameters of each structure in the fuzzy system are tuned automatically by the EFM. The results demonstrate the performance of the proposed approach for the legged robot.

In this study, we consider a problem of forecasting daily city gas demand of Korea. Forecasting daily gas demand is a daily routine for gas provider, and gas demand needs to be forecasted accurately in order to guarantee secure gas supply. In this study, we analyze the time series of city gas demand in several ways. Data analysis shows that primary factors affecting the city gas demand include the demand of previous day, temperature, day of week, and so on. Incorporating these factors, we developed a multiple linear regression model. Also, we devised a sampling procedure that selectively collects the past data considering the characteristics of the city gas demand. Test results on real data exhibit that the MAPE (Mean Absolute Percentage Error) obtained by the proposed method is about 2.22%, which amounts to 7% of the relative improvement ratio when compared with the existing method in the literature.

10년 후, 미래의 자동차는 더 이상 단순한 운송수단이 아닌 우리의 삶을 윤택하고 더욱 풍요롭게 만들어주는 일상의 공간(업무 휴식 정보)으로 진화 발전할 것이다. 이러한 자동차 패러다임 변화의 중심에는 지능형자동차 기술이 자리하고 있다. 지능형자동차 기술은 자동차산업뿐만 아니라 사회 경제 전반에 미치는 파급효과가 매우 크기 때문에 국가 경쟁력 강화를 위한 차원에서도 큰 가치를 지니고 있다. 또한 미래형자동차는 안전성 편의성 향상이라는 소비자들의 다양한 요구와 시장의 확대를 희망하는 기업의 요구가 잘 맞물려 있기 때문에 향후 기술개발에 대한 예산 확충 및 지원 확대가 절실히 필요하다. 지난 1990년대부터 지능형자동차 개발에 적극적으로 참여한 일본, 미국, 유럽 등 자동차선진국은 최근 각종 신기술을 개발해 시장에 내놓고 있다. 자동차 10대 강국 중하나인 한국은 21세기 세계 자동차시장 선점과 오는 2010년 세계 3위의 기술 강국으로 도약한다는 야심찬 계획을 세우고, 지난 2003년에 미래형자동차를 국가 '차세대 성장동력산업'으로 선정하였다. 이에 따라 국가연구개발사업인 '미래형자동차사업'을 출범시켰으며, 국내 자동차업계는 물론 대학 및 연구소 등과 연계하여 '지능형자동차' 등 3분야의 관련 핵심기술 개발에 박차를 가하고 있다. '지능형자동차 기술개발'이라는 비전과 목표를 달성하기 위해서는 IT기술과 자동차와의 융합기술 개발이 그 무엇보다 중요하다. 우리나라가 세계에 IT강국으로서 명성을 널리 자랑하고 있다는 점에서 지능형 자동차의 미래는 밝다고 할 수 있지만, 관련 분야의 인적자원 네트워크 구축이 보다 탄탄하게 다져지지 않는다면 이는 그저 '빛 좋은 개살구'에 지나지 않을 것이다. 끝으로 국내에서 진행되는 ITS 관련 프로젝트와 지능형자동차 개발 연구과제의 유기적 연계와 효율적 추진, 지능형 자동차 시험 평가방법 표준화, 국제 기술 표준화 및 안전규제에 적극 대응, 지능형자동차 신규제품 및 서비스의 도입을 위한 제도개선 및 정비 등에, 정부와 산 학 연이 지혜를 모아 중점 실행계획을 수립하고 행동으로 옮길 때 우리의 지능형 자동차 미래는 밝을 것이다.
