Railway R&D technology development projects for the economic value of technology development does not mention the estimated economic impact on future policies must reflect the issues that are raised. In the research phase of technology development by providing value and economic effects can increase the utilization of technology development are considered. However, some items in some way to analyze and quantify its effect on what the procedures are not standardized, not as needed by individual researchers and analysis by providing a variety of reliability problems can occur. Therefore, the development of technologies to measure the value and economic impact analysis and the development of a standardized manual is needed. In this paper, development of railway technology R & D performance (technical, economic) to be estimated by an objective analysis of standardized and that man should aim to create. And the standard manual of the national economic effect in the development of technologies (production inducement effect, the effect of import substitution industries, including analysis using the taxable year), due to technology development and economic benefits (investment in railways in the handbook and the feasibility of the proposed railway project to produce various ally standards), technology development, and on which to base the valuation will.

The railway safety in Koreaisthreatenedduetotherestructuring of the railway industries, introduction of the Korea Train eXpress (KTX) and electrification of the conventional lines. Many technical backgrounds are required to control railway accidents as low as reasonably practicable, such as a railway safety act, safety standards, and safety assessment infrastructures. Korean government and the Korea Railroad Research Institute (KRRI) are conducting an integrated R&D program for improvement of the railway safety, where the target is to reduce the accident fatalities by half. The program is composed of three parts; the safety system engineering and the program management, the establishment of a safety management system, and the development of techniques for assessing and preventing major railway accidents. Details of the research programs are explained in this paper, where risk is used as the major control measure.

The domestic railway parts and equipment manufacturing industry is mainly focused on SMEs, and the majority of them are suffering from profitability because they cannot build economies of scale. Besides, they have survived in the form of importing technology products from overseas advanced countries and delivering them to domestic railway operators rather than having in-house technology. Therefore it is necessary to study whether the problems of the current railway industry can be identified and improved and at the same time, whether the government's railway industry development policy is properly reflected. literature studies related to technology commercialization, and conduct surveys of AHP questionnaires on the experts of the manufacturing industry of SMEs, academics / research institutes of the railway industry. After that, the Level 3 activation method AHP analysis was additionally performed on the important factors of Level 2 that have the highest importance and priority in Level 1. As a result of the AHP analysis, 'Technical Connectivity' was the most important method in the technical factor, and SME experts and academic and research institute experts were highly evaluated for 'commercialization ability' Competence in terms of importance. As for external support factors, it was analyzed that SME experts "support for manpower development" was important, while the other two group experts research and development support was important. In this study, the priority of the government support and policy priorities are suggested according to the capabilities of the railway manufacturing SMEs before the future R&D support.

There is a growing interest in convergence. National R & D is also providing various policies and institutional support to promote convergence research. Convergence research, however, does not clearly specify its characteristics at the academic and government levels. This research proceeds with the process of collecting, refining, analyzing, modeling, verifying and visualizing national R & D data through the National Science and Technology Information Service (NTIS). The method is to derive the convergence research characteristics and to derive through text mining, focusing on the unstructured information of national R & D project data. The study confirmed that there was a difference in perception between the definition of converged research and the research site. In order to improve this, the research suggested that convergence among research subjects, collaboration among research topics reflecting various backgrounds and characteristics of researchers, and analysis of characteristics of convergence research using information were suggested in the process of establishing convergence policy.

HRTF 를 사용하여 가상적인 음향 효과를 내는 시스템에서의 음의 왜곡은 필수적이다. 하지만 음성과 같은 사람이 민감하게 느끼는 부분에서의 음의 선명도 저하는 다른 대역의 왜곡보다 더욱 크게 느껴진다. 그리고 모노 및 두 채널의 주파수 특성이 비슷한 스테레오에서는 음질을 보상할 수 없다는 단점이 있다. 본 논문에서는 이러한 음의 선명도의 저하를 유발하게 하는 가상 음향 발생 필터의 특징을 분석하고, 간단한 필터 설계에 의해서 본래의 가상 음향을 그대로 유지하면서 선명도를 높일 수 있는 방법을 제시한다. 제시한 방법은 특히 모노 및 뉴스모드와 같이 음성이 많이 들어 있는 부분에서 뛰어난 성능을 보인다.

Volcanic ash components of Mt. Baekdu were estimated to response the change of water quality environment affected by Mt. Baekdu volcanic ash ejected during eruption. Then the change of water concentrations according to the sedimentation of volcanic ash components were analysed. To estimate volcanic ash components of Mt. Baekdu, similar volcanos were selected through the comparison of main foreign volcano's magma type and the selected volcanic ash components supposed as Baekdu Mountain's. To analyse the change of water concentrations, the change of harmful components affected by volcanic ash sedimentation were analysed and the results were compared with domestic drinking water quality standard. As the result, Al, Cd, F, Fe, Pb, Mg, Cl and Sr could affect to water quality. Among those components, concentrations of Cd, F, Fe, Pb and Mg were estimated to exceed the drinking water quality standard.

Since railway industry is becoming important globally, Korea government and private enterprises invest huge amount of R&D expenditure to develop railway technologies. However, ratio of successful commercialization of technology is very limited. establishment strategy of specialized institution for commercializing railway technologies is very important research issue. For example, France and Japan support railway commercialization through the specialized organization in leading the global railway industry. This study propose the critical success factors of the establishment of railway commercialization and suggest relative importance of CSF's through the hierarchical analysis. As a result, the financial resource plan(0.505) and the commercialization strategy(0.193) are important factors at the first level, and the government funding plan(0.220) and the legal/institutional support(0.150) are important factors for the commercialization organization at the second level.

This study measures and compares the performance of research and development (R&D) programs in government-funded research institutes (GRIs) in terms of qualitative and quantitative approaches to find out strategic insights for improving performance evaluation policy. In particular, we adopt the evaluation results from the real data of K institute in 2015 for a qualitative evaluation and the results of data envelopment analysis (DEA) for a quantitative evaluation. Comparative analysis of the R&D performance of 14 programs finds that the difference between the evaluation results of qualitative and quantitative approaches is significant. From this finding, we suggest several strategic directions to complement two approaches each other.
