  • This paper presents the economic validity with the cost/benefit analysis on establishing R&D Supreme Academy. To evaluate the profitability of R&D Supreme Academy, willingness to pay (WTP) is measured by contingent valuation method (CVM) and then the net present value (NPV), internal rate of return (IRR) and benefit/cost ratio(BCR) are calculated. The results of economic evaluation verified that the establishment of R&D Supreme Academy is timely and effective in an economic perspective.

  • The driver model based on the ACT-R cognitive architecture was developed in order to predict the performance and cognitive workload of a driver operating HVI devices. In the 10 HVI tasks, the predicted performance time and cognitive workload by the ACT-R driver model was well matched and highly correlated with the mean of performance times and subjective workload ratings from 15 participants, respectively. It is strongly proposed that the ACT-R driver model in this study can be applied to evaluate the usability of a new HVI design with less cost in the early stage of system development.

  • This paper analyzes the economic effects of the S&T Innovation, R&D, human resources and investment on the economic growth using 18 countries. We have obtained the somewhat mixed results on the existence of unit root roots in variables. While most of Pedroni cointegration tests show that there are no panel cointegration among the variables, Kao cointegration test shows that there is the panel cointegration among the variables such as GDP, human capital, R&D investment and patent. Kao cointegration test result shows that human capital, R&D investment, patent economic growth seem to have the panel cointegration or the long-run relationship among them as a whole. The estimation results of individual OLS and panel estimation show that the human capital, R&D investment and technology innovation or patent had positively significant effects on economic growth or GDP.

  • In this paper we give conditions for the existence of, and describe the asymtotic behavior of, radial positive solutions of the nonlinear elliptic equation of Emden-Fowler type with convection term ∆p u + 𝛼|u|q-1u + 𝛽x.∇(|u|q-1u) = 0 for x ∈ ℝN, where p > 2, q > 1, N ≥ 1, 𝛼 > 0, 𝛽 > 0 and ∆p is the p-Laplacian operator. In particular, we determine ${\lim}_{r{\rightarrow}}{\infty}\,r^{\frac{p}{q+1-p}}\,u(r)$ when $\frac{{\alpha}}{{\beta}}$ > N > p and $q\,{\geq}\,{\frac{N(p-1)+p}{N-p}}$.

  • Electric vehicles contribute greatly to energy conservation, $CO_2$ reduction and energy security through high fuel economy and various electric sources. Electric cars have a huge economic impact. More than 14 million hybrid electric cars have been sold worldwide. More than 3 million plug-in electric vehicles have been sold worldwide. The environmental impact depends greatly on the amount of national power generation, and as the electric grid becomes more and more carbon-intensive, countries are increasingly adopting hybrid and electric vehicles. Electricity is expanding beyond cars. Electric buses, trucks, and ships have similar benefits.

  • 도서관에 RFID 시스템을 도입함으로써 업무의 효율을 높일 수 있다. R-LIM2는 도서의 위치까지 안내하는 기능을 제공하는 RFID 기반의 진보된 도서관리 시스템이지만 위치 추정과 내비게이션에 다수의 안테나 및 별도의 PDA를 사용함으로써 경제적으로는 비효율적이었다. 이에 본 논문에서는 R-LIM2의 내비게이션 기능을 별도의 기기 없이 사용자가 휴대한 스마트폰으로 가능하게 하고, 기존에 구축되어 있는 무선 네트워크 인프라를 활용하여 위치 추정이 가능하게 함으로써 보다 경제적이고 효과적인 도서위치 검색 시스템을 개발하였다.

  • Environmental R&D management system has been analyzed with LCA method. Based on the analysis, we found the following four elements were essential for improving effciency of environmental R&D management system: establishment of an information clearinghouse that collects and distributes information on the status of the domestically owned environmental technology, Periodic survey of the environmental technology demand to give guidance in selecting the environmental R&D project that are to be subsidized, dissemination of information on the technology transfer and commercialization assistance program, and increased funding as well as the expansion of project categories eligible for R&D subsidy.

  • 본 연구는 R&D 정보 시각화를 위한 네비게이션 선행연구이다. 지금까지 R&D서비스에서는 연구 기획 단계에서부터 사업화에 이르기까지 기존의 연구 성과에 대한 조사 분석을 포함해서 해당 연구 주제에 대하여 기술동향, 시장분석, R&D정책 등 다양한 정보를 종합적이고 전략적으로 활용할 수 있는 정보 서비스가 부족하거나 제한적이었다. 이런 문제를 해결하기 위하여 본 논문에서는 서비스 디자인 방법론에 입각하여 R&D정보서비스의 서비스 디자인 프로세스를 사용하여 R&D 담당자와 UX 디자이너가 참여하는 사용성 평가와 서비스 디자인 방법론 수행 후 사용자 니즈를 분석해 보았다. 국가R&D정보와 관련된 정보처리기술 및 정보자원에 대해서는 기존 KISTI에 가지고 있는 국가R&D정보와 NDSL를 연계하고 이를 활용하여 연구자의 R&D활동에 관련된 문제해결을 지원하는 서비스 체제를 구축하고자 한다. 본 논문에서는 국가R&D정보 서비스 체제 구축을 위해 서비스 디자인 방법론과 사용자 분석을 통해 R&D정보 서비스의 개선 방향을 알아본다.
