계통에 외란이 발생하면 전압 붕괴 현상으로 이어져 제어될 수 없는 부하손실이나 캐스케이딩 현상의 형태로 발전 될 수 있다. 심각한 경우에 광역정전으로 확대되는 문제점이 생기는데, 이를 방지하기 위한 방안으로 최소한의 부하차단을 통하여 계통을 안정화시켜야 하며 불필요한 부하차단을 방지하기 위한 부하차단 다단계화가 수행 되어야 한다. 본 논문에서는 모선 전압의 민감도에 따른 적정한 부하차단 개소를 선택하였으며 부하차단 의사결정 방안으로 전압 변동률을 고려하여 다단계 부하차단 방안을 검토하였다. 전압변동율의 계산을 위하여 Least square 기법이 적용되었으며 2008년도 하계 최대부하 계통에 대한 동적 해석을 수행하였고, 계통 해석 결과를 바탕으로 이전에 제안 된 방안들에 비하여 향상되고 발전된 효율적인 저전압 부하차단 방안에 대하여 논의하였다.

최근 낙동강 유역은 수질개선의 가시적 효과가 미흡하고 취수원 이전 방안에 대한 지역간 갈등으로 먹는 물에 대한 불안감이 지속되고 있다. 또한 맑은 물 공급을 위한 다양한 개선안에도 불구하고 유역 구성원간 이해관계가 복잡하여 실효성 있는 대책추진이 어려운 실정이다. 따라서 낙동강 상하류에 맑은 물을 안정적으로 공급할 수 있는 최적 물 배분 대안을 마련할 필요가 있다. 이 때 유역 내 다양한 수원을 활용하여 맑을 물을 확보해야 하며 특정 지역의 이익만을 고려하는 것이 아닌 모든 지역에 편익을 줄 수 있는 대안을 마련할 필요가 있다. 본 연구에서는 낙동강 유역 중 최근 갈등을 빚고 있는 부산·경남지역의 취수원 이전에 따른 물 공급 안정성을 평가하여 제시하였다. 이를 위해 제안될 수 있는 몇 가지 대안에 대한 장래 물 수급 전망을 수행하여 대안별 용수 공급 가능성을 검토하였으며 대안별 유역의 물 공급 안정성에 미치는 영향을 평가하여 제시하였다. 취수원 이전과 같은 맑은 물을 공급하기 위한 다양한 대안들은 해당 지역뿐만 아니라 다른 지역의 물 공급에도 영향을 줄 수 있기 떄문에 보다 광범위한 분석이 요구된다. 분석 결과는 향후 낙동강 유역의 맑은 물 공급 사업에 대한 물 공급 관련 다양한 정보를 제공함으로써 보다 합리적이고 투명한 대안 선정에 기여할 수 있을 것으로 기대된다.

This article proposes the unified an arm's length price of transfer pricing for thin capitalization since the scope of permanent establishment has been enlarged under Digital Economy and the implementation of Blackchain system to resolve the drawback of finding an arm's length price. The rule of current thin capitalization runs against the non-discrimination of taxation of the tax treaties and the national treatment which deals fairly with goods, sercice and capital money within the country under the treaty of commerce and navigator. In addition, the information of comparable uncontrolled debt are not available of current system to prove the debt which is not subject to the rule of thin capitalization. The united an arm's length price of transfer pricing for thin capitalization can apply to foreign investment as well as domestic corporations, thereby resolving the problem of the non-discrimination of taxation of the tax treaties and the treaty of commerce and navigation. The availability of transaction level data through Blockchain platform to decide whether the debt can be subject to thin capitalization can resolve the issue of comparable uncontrolled debt transaction which can't be found in current business transactions. This article should shed light on the proposing of the unified an arm's length price of transfer pricing for thin capitalization and Blockchain system to prevent the income shifting. This propose provide implication for policymakers on current system of thin capitalization and arm's length principles.

The Korean government is aiming to strengthen industrial and national competitiveness through the promotion of cooperation between universities, public research institutes and industry and vitalization of technology transfer. In 2013 and 2014, the Ministry of Trade, Industry and Energy and Ministry of Science, ICT and Future Planning have announced policies to support SMEs by public research organizations. In addition, in 2015, the 'Korean Fraunhofer support system', which pay government subsidies according to the amounts of private R&D funds was adopted. However, there are some concern about the government's policies. There is yet disclosed how these policies affect technology transfer because industrial R&D funding has not been activated in Korea unlike German. Therefore this paper analyzes effects of relationship between universities, public research institutes and external organizations on performance of technology transfer based on the Triple Helix Model. Empirical results show that the relationship with the government has a significant impact on the resource security and the relationship with the industry has a significant effect on the diffusion of the performance. In addition, a public research institute was selected and case analysis was conducted to suggest policy implications for improving the technology transfer performance of universities and public research institutes.

The purpose of this study was to present the future directions for strengthening the TLO(Technology licensing office)s' expertise of universities by examining the impact on utilizing the university management experts for patents and technology transfer. To identify the specific effects of dispatching patent management experts, this study was conducted under various conditions, such as the dispatch status, the dispatching duration of patent management experts and the starting year of dispatching them. The data were analyzed by utilizing the data of the KIPSI's supporting program of dispatching the patent management expert to universities and the data of University Information Disclosure site. The data from a total of 110 four-year universities from 2008 to 2013 were used. According to the analysis result, the technology transfer's performance and technology transfer's income of universities of utilizing the patent management experts compared to universities not utilizing them appeared to be high. Technology transfer and technology transfer income appeared to be higher with a longer period of utilizing the patent management expert at university. This suggests that the direction is required to provide the plan for a longer period to maximize the effect of the program "The dispatching a patent management expert". The technology transfer's performance and technology transfer's income did not increase according to the year of dispatched the patent management expert at the university. A comparison of before and after dispatching, the technology transfer performance appeared to be high after dispatch. This suggests that the effects of dispatching the patent management experts at a university can be interpreted as a subsequent effect, rather than an immediate effect. Therefore, it does not simply limit the effectiveness of the dispatch business in the short term, but it needs to activate the technology transfer organization, such as a patent management expert in the long term.

As national R&D is increased in scale, technology transfer has garnered more attention in terms of utilizing R&D outcomes. In this study, we analyzed influencing factors to technology transfer, as a way of utilizing R&D results, using data on national R&D. The analyses was performed with 3 subjects: university, government research institute and industry. When royalty is used as a dependent variable to measure the performance outcomes of technology transfers, the analysis showed that R&D funds have positive influence on all three subjects. In terms of government research institute, the influence was significant whether the location is the capital area or Daejeon city. With regards to industry, factors such as whether the project is a cooperative research, applied research, and the research to technology transfer period were found to have remarkable influence. On the other hand, when the number of cases of technology transfer was used as a dependent variable, the analysis indicated that R&D funds have significant impact on university, while for government research institute, the significant influencing factors include both R&D funds and the research to technology transfer period, and for industry have positive influence on applied research. It is therefore necessary to make differentiated policies considering the R&D organizations in order to improve the efficiency of technology transfer performance.

Conservation measures for excavated and surveyed buried cultural heritages are decided by the administrator of the Cultural Heritage Administration according to their scientific and historic values. However, management, preservation, and use after relocation and restoration remain unsystematic. An issue regarding preservation plan and use has arisen due to the damage of preserved heritages and protective facilities. Thus, this study aims to suggest a plan for preservation and use by investigating the present conditions of the preserved heritages in the Chungbuk area. Results showed that there are 43 preserved heritages in Chungbuk, most of which remain unmanaged systematically irrespective of the managing body. Remainder and protective facilities have been damaged due to wrong preservation treatments and selection of materials, and a problem also rises in terms of utilization, such as exhibition, education, and experience of preserved heritages. To improve such problems, a medium and long-term plan shall be established for the improvement of legal and institutional instruments, securing of budget, increase in professional manpower, development of standardization and inspection manuals, continuous monitoring, preventive preservation, research on relocation methods and materials, listing, and the creation of specialized museum and complex theme park. If a preservation plan suited to the investigated heritages can be developed, heritages can be preserved and managed more systematically and scientifically, and be used for various purposes like education, exhibition, public relations, etc.
