The focus of this paper falls on assessing how well rule of crafting government R&D institution spin-off companies(GRSCs), legitimatized to boost up technology commercialization of government research institutions(GRIs) at Daedeok Innopolis in 2006, affect the better business performance of GRSCs, but also delivering alternatives of driving up their better business. First of all, this paper evaluate a management performance of GRSCs at the financial aspect by taking 5 different GRSCs cases among 16 to measure the overall performance of GRSCS's Technology commercialization. Second, this paper assess the effectiveness of GRSCs to bring the better performance of technology commercialization. Third, this paper suggest soft program-centered technology commercialization model, rather institution and ceremonial-oriented one, for GRIs. Overall, the outcomes of this paper will contribute to accommodate the rule of GRSCs attaining goals set in the initial policy domain.

Purpose: This paper aims to derive improvement measures, in terms of legal and technical aspects, which can reduce effectively the casualties caused by drowing accidents. Method: Firstly, we checked the status of drowing accident management and carried out the interview of field private safety guards. field private safety guards. In addition, surveys were conducted on safety personnel and managers. Based on survey results, we are lastly analyzed the specific problems and reviews the improvement measures from technical and legal aspects. Result: As an analytical result, it was considered that supplementary supporting tools such as CCTV, monitoring devices using IoT and artificial intelligence technologies were necessary to prevent drowning accident, and qualification with limited authority should be added to the private safety guard because of the lack of regulation. Conclusion: In order to manage water safety effectively, a comprehensive water safety management system should be established that integrates people and equipment through systemic education of security personnel, authorization of enforcement, and introduction of surveillance equipment.

중대한 해양사고를 예방하고 잠재적인 해양사고의 원인을 제거하기 위하여 해상교통안전진단 제도가 "해상교통안전법" 개정('09. 5. 27)을 통해 정식 제도화되었다. 법 시행 이후 수행된 연구 중 하나인 '해상안전진단제도의 기술기준 및 고도화 연구'에서는 관련 평가 중 하나인 해상 교통혼잡도 평가에 사용되는 환산교통량 및 표준선이 현재 선박의 대형화 및 고속화 추세를 반영하고 있지 못함을 제시, 개선의 필요성을 말하였다. 이에 먼저 관련한 일본의 이론과 국내 진단대행업자의 평가 이론 현황을 파악 분석한 바, 이론 및 진단대행업자 별로 분석요소들을 다르게 사용하고 있어 표준화의 필요성을 발견하였고 또한 2010년 선박 입출항 통계를 이용한 선박현황을 분석한바 이론에서 사용하는 표준선과는 상당이 차이가 있음이 나타났다. 이후 관련 개선을 위한 기술기준(안)을 제안하여 전문가들의 의견 수렴과 이를 분석한 결과, 비록 소수의 상반된 의견이 있었지만, 표준선 변경에 따른 환산교통량 변화가 해상교통혼잡도에 미치는 영향은 그리 크지 않음을 알 수 있었다. 마지막으로 평가관련 개선을 위한 최종 기술기준(안) 및 앞으로 발전방향을 제시하여 해상교통 혼잡도 평가 발전을 위한 연구기반을 마련하고자 하였다.

TRIZ was developed and refined in the Soviet Union between 1946 and 1985 by Genrich Altshuller. Its primary application has been for solving inventive problems in the areas of engineering. But, recently the elements of TRIZ began to be applied non-technical areas by Darrell Mann. TRIZ theroy was brought into South Korea in 1995 and it is used by the LG, SAMSUNG, POSCO. TRIZ is simply not the tool for technical problem solving, covering many areas of comprehensive approach is being recognized. TRIZ is a methodology for defining problem, finding root cause through RCA(Root cause analysis), defining technical contradiction and physical contradiction. TRIZ overcomes contradiction and purses problem solving method through innovation. TRIZ is a problem solving method in this study using the principles of non-technical fields applied to the improvement of the logistics area study. The method to overcome contradiction is 40 principles. It is possible to generate idea by using 40 principles. This study was applied to logistics field of non-technical area by using TRIZ principle.

This study examines the damage to the submarine's escape trunk hatch spring through microstructure analysis. The cause of the escape trunk's damage during the submarine's construction and its improvement measures were reviewed. To determine the cause of breakage of the escape trunk spring, samples were taken from the damaged product and analyzed for chemical composition, hardness, and microstructure. In particular, the breakage part of the spring was analyzed in-depth by using a scanning electron microscope to determine the cause of corrosion destruction. Finally, a spring shape design method was proposed through the investigation of the cause of spring breakage. In addition, a newly improved spring was produced by applying a nylon coating with excellent corrosion resistance and abrasion resistance. Applying to an actual submarine trunk hatch revealed that the coating peeling phenomenon due to the contact between the springs is significantly improved when the hatch is opened or closed compared to the existing products.

In this study, we aim to derive a solution from the structural analysis for electrical failure of single board computers for computing navigation information. By analyzing the characteristic factor, we identify that crack occur on the central processing unit board due to a certain structural problem, and that the physical effect by the crack make communication function be impossible to perform, which it causes booting error. In order to find the location of excessive stress causing the crack, structural analysis for the single board computer is done. From the structural analysis, the areas where stress concentration occurs are identified, and improvement methods changing the structures are developed. As a result, we shows that stresses are reduced entirely on the stress distribution for the improved structure. In addition, heat analysis shows that changing the structure to reduce stresses is not affect to the heat radiation, and the thermal resistance of the actual equipment is verified by measuring the temperature of the heat sink applied with the improved structure.

Recently, the korean-style houses are shedded new light. So, this study analysed what it is required and improved for preservation and vitalization of traditional korean village. At tool of analysis and systemic analytical approach, the problem of traditional korean village figured out. and then, the method and Importance of improvement are deducted. As a result of this study, it is represented to need that the preservation of architectural factors in the self korean-style house, but the more important things are deducted cooperation of citizen, political support and consideration of government at level of urban planning. There must be considered for planned conservation and development, increasing value by recreation of historicity and culture in city unit of community.

The Radiation Emergency Plan (REP) can be divided into a technical and an administrative responses. The domestic NPP's REPs are reviewed from the viewpoint of the administrative response and improvement methods are also suggested in this treatise. The fields of the reviews are the composition of the emergency response organizations, the activation criteria of the organizations, the selection of the staffings and the reasonableness of the REP's volume. In addition, the limitations of the current radiation exercises are reviewed and the improvement method of the exercise is presented. It is expected that the suggested recommendations will be helpful in establishing useful REPs and making practical radiation exercises in Korea.
