Developed countries, especially in road construction and management fields, introduce new road porjects such as National Scenic Byways Program(NSBP program) in USA and the Eco-road project in Japan. This study develops a conceptual model for deploying new road projects in Korea. The four step approach is suggested to create new road projects, including foundation of an act based on the existing Road Act, creation of new road project ideas, development of evaluation process and guidelines, and enhancement of an administrative scheme. To create new road projects, three different ways are devised; (1) designation of national roads having uniqueness in overall spectrum, (2) designation of roads having intrinsic values in a different aspect, (3) designation of single structures of engineering outcomes such as bridges, tunnels, new design techniques, considerable Value Engineering output, and well analyzed Life Cycle Cost Analysis practices. For the evaluation process, NSBP program of USA and/or Sustainable City Award program of Korea would be recommended. An administrative scheme and integrated funding process for the new road projects are also suggested based on evaluation of tasks of each team or division of Korea Ministry of Construction and Transportation.

This study empirically investigated the influence of entrepreneurship and technological commercialization capabilities of domestic small and medium-sized manufacturing enterprises on financial performance by mediating technological performance. To achieve this, a survey was administered to their hands-on workers in charge of R&D. The survey results were analyzed through the structural equation model as follows. Entrepreneurship had an effect on technological and financial performance. Technology commercialization capability had an effect on technological performance. However, technological commercialization capabilities were evaluated to be inferior to financial performance, which can be interpreted as financial performance being judged as different between individuals or organizations in terms of technological commercialization capabilities. Technological performance had an effect on financial performance. Technological performance played a mediating role in the effects of entrepreneurship and technology commercialization capability on financial performance. Consequently, it is very important for entrepreneurship and technology commercialization capability to develop new products and improve corporate performance with insufficient financial status or operating system completion.

유역 물순환 개선 기술은 기후변화 및 토지이용변화가 진행 중에 있거나 예상되는 지역에 대하여 강우-유출수를 지연, 저류, 침투시켜 지속가능한 물순환체계를 유지?회복하도록 하는 기술이라 할 수 있다. 기후변화 및 토지이용변화에 따른 영향을 평가하고, 지속가능한 유역 물순환체계를 구축하여 적응 전략을 체계적으로 수립하기 위해서는 물순환 개선 기술의 정립 및 개발이 필수적이다. 그러나 현재 유역 물순환 개선기술은 일부 시가화 지역에 국한되어 있어 유역 규모의 개선 전략을 수립하는데 한계가 있다. 또한, 물순환계의 변화량을 평가하기 위한 모형화 기법 역시 해외에서 개발된 기술을 여과 없이 도입하여 국내의 환경을 충분히 반영하기는 어렵다. 개발된 유역 물순환 개선 및 평가시스템은 기존 국가연구개발사업을 통해 개발되고 사업화에 성공한 바 있는 유역 물순환 평가 모형인 CAT(Catchment hydrologic cycle Assessment Tool)을 수정 및 개선하여 기후변화에 따른 영향을 평가하고 적응 대책을 수립하기 위한 실무적인 소프트웨어이다. 침투트렌치, 식생침투트렌치, 습지, 저류지, 빗물탱크 등의 물순환개선시설에 대한 효과를 평가할 수 있도록 개별시설의 제원에 따른 물순환개선 효과를 정량적으로 평가하여 제시한다. 기후변화에 따른 장기간의 유역 물순환을 평가하기 위해서는 물리적 매개변수 기반의 수문해석 보다는 단순환된 개념적 매개변수 기반의 집중형 장기유출 해석이 필요할 수 있다. 따라서 국내외에서 많이 사용되고 있는 장기 일유출 모형(GR4J, GSM, HBV, SYMHYD, TANK, TPHM 등)을 유역 물순환 개선 평가 플랫폼에 탑재함으로써 소유역의 특성을 반영한 기후변화 적응 일유출 해석이 가능하도록 하였으며, 각 모형들의 매개변수는 수동보정 외에도 SCE-UA를 이용한 자동보정이 가능하도록 시스템으로 구축하였다. 개발된 유역물순환 개선 및 평가시스템은 실무적 차원에서 기후변화에 따른 유역 물순환 개선 기술을 적용하고 평가하는데 있어서 매개변수 입력자료 구축에 따른 자원 소요 시간 및 시스템 개발 비용을 획기적으로 단축시켰으며 국외 의존도가 높은 수문 해석모형을 국내 기술로 개발함으로써 기술자립도를 높이고 국내 및 해외의 유역의 성공적인 적용을 통하여 성능을 입증하였다. 기후변화에 따른 수자원의 재평가, 개선시설의 정량적 평가 및 하천유역의 수자원관리 실무에 적용성이 높을 것으로 기대된다.

As the need for improvement of transparency and fairness in the selection of national R&D projects has been continuously raised, we analyzed the impact on the evaluation selection results by evaluation indexes for The land transportation technology commercialization support project and searched for ways to improve indexes using the analysis results. As for the research data, it were applied as selection results of new R&D projects and evaluation indexes in two fields(SME innovation and start-up) in 2021. Logistic regression analysis is used for the influence of each evaluation indexes on the evaluation result, and for the regression model, evaluation indexes with low influence are removed in advance through artificial neural network multiple perceptron analysis to improve the reliability of the analysis results. As a result of the analysis, in the field of SME innovation, the influence of the evaluation index on the workforce planning was the lowest and the influence of the appropriateness of commercialization promotion plan was the highest. In the start-up field, the influence of the evaluation indexes for technology development suitability, marketability, and suitability for carrying out the project were estimated to be similar to each other, and the influence of the technology evaluation index was found to be the lowest. The analysis results of this thesis suggest the need for continuous improvement of selection and evaluation indexes, and by using the analysis results to select a fair R&D institution according to the selection of appropriate indexes, it will be possible to contribute to deriving excellent research results and fostering excellent companies in the field of land transportation.

The Ministry of Land, Infrastructure and Transport has also been promoting the commercialization of land transport technology to commercialize the technologies owned by small and medium-sized venture companies, and to support the transfer and commercialization of public technologies. At this point, in order to improve the investment effect of subsequent new projects and to select excellent research institutes, it is necessary to establish a valid evaluation index system suitable for the purpose of the project. The evaluation index system for subsequent new projects should be linked to the project objectives and goals of the preceding project, and should be selected in consideration of existing evaluation indicators to prevent interruption of research results. Therefore, this thesis sets the evaluation index system into multiple scenarios through hierarchical cluster analysis using the evaluation result data for each evaluation committee for small and medium venture companies participating in the land transportation technology commercialization support project, and then analyzes the structural equation model. As a result of scenario analysis, considering the measurement effect of each path representing the causal relationship between evaluation indicators and the effect of each evaluation index on evaluation items, the scenario with the highest impact on the evaluation result was selected as an improvement plan.

Recently, as there are a rise in the standard of living and higher concerns of an electromagnetic wave and environment, undergrounding the aerial cables which are supported by large pylons and generally considered as the least attractive feature of an urban area is on an increasing trend to improve aesthetic benefits and electric reliability. This study applied Contingent Valuation Method (CVM) which is expected to become an effective tool to measure indirect benefit to estimate the substantial benefits of undergrounding overhead power line projects in an urban area. The tunneling construction project of the 345kV Shinsungnam electric power cable in Seongnam city was selected and a hypothetical scenario was given to respondents to determine their levels of Willingness to Pay (WTP) for undergrounding overhead power lines. The result from the estimation of the WTP of undergrounding overhead power lines in Seongnam city was calculated as approximately 17.1 billion won. Placing existing overhead lines underground is difficult to justify economically. Most undergrounding costs appear to be justified by aesthetic and public policy considerations. Therefore, considering the result of this study, undergrounding overhead power lines is of great benefit to public.
