In this study, Revealed Comparative Advantage (RCA), Symmetric RCA, Trade Specialization Index (TSI) were used to analyze the service trade competitiveness of Korea, China, and the United States. As a result of the analysis, first, Korea is at a comparative disadvantage as most RCA index values are less than 1 and most SRCA index values are measured as negative numbers (-), Korea was found to be less competitive than the United States and China. Second, looking at Korea's global TSI index, it can be seen that Korea is closer to import specialization than export specialization due to its overall lower competitiveness compared to the United States and China. Accordingly, in order to strengthen Korea's service trade competitiveness, financial support strategies for service export companies and the K-content export base must be strengthened. And there is a need to create an export investment fund to foster global companies and develop policies to strengthen the competitiveness of the tourism sector.There is a need to foster promising items related to software (SW) and information and communication technology (ICT), deregulation and branding are needed to revitalize medical service exports.

In this study, the reinforcement effect of the compression-only bridge seismic reinforcement method, which is mainly applied to old bridges, was studied through SSI analysis. As the analysis conditions, acceleration magnitudes of 0.1g, 0.15g, and 0.2 g were applied, and long-period and short-period seismic waves were applied. As a result of the analysis according to the assumed ground characteristics and structure size, the horizontal displacement at the reinforced section was reduced by about 9%, and the long-period seismic wave had a 95% larger displacement than the short-period seismic wave. In addition, an increase in acceleration of 0.1g resulted in a displacement of about 50%, and a large increase in displacement was observed in long-period seismic waves. As a result of the analysis, in the case of the compression-only bridge seismic reinforcement method, there was a reinforcing effect, so the field applicability was excellent.

In this study, a seismic reinforcement method was studied to improve the seismic performance of aged bridges. The construction method developed in this study is a compression-only bridge seismic reinforcement method, and has excellent economic feasibility and workability compared to existing construction methods. In the case of aged bridges, there was an advantage that could compensate for the disadvantages that it was difficult to apply the existing reinforcement method. For the newly developed method, the effect of reinforcement was analyzed through resin analysis. As a result of the analysis, when the reinforcement was applied, the axial reinforcement effect was excellent, and the field applicability was excellent as it showed better results than the existing seismic isolation backing method.
e-Trade의 연구동향 및 향후 연구방향에 대한 고찰
장유식(Yu-Sik Jang),김정환(Jeong-Hwan Kim) 중앙대학교 한국전자무역연구소 2010 전자무역연구 Vol.8 No.1
최근 정보통신 기술의 발전과 인터넷 사용의 급속한 확산은 기업 활동의 세계화를 가속시키고, 상거래 방식과 상거래 관행을 변화시킴으로써 21세기 새로운 상거래패러 다임인 전자무역(e-Trade)으로 신속한 전환이 중요한 이슈가 되고 있다. 전자무역에 대한 연구는 그동안 활발하게 진행되어 왔다. 전자무역의 역할이나 내 용, 발전방안 등을 중심으로 이루어져 왔으며, 최근에는 전자무역의 세부내용을 넘어 서 전자무역이 다루어야 할 연구범위와 연구방법론에 대해서도 논의가 이루어지기 시 작하고 있다. 본 논문의 목적은 전자무역의 연구범위 및 방법론에 대해 살펴보고, 최근 전자무역 의 연구동향을 학위논문과 학술지로 분류하여 분석하고, 전자무역에 대한 연구의 개 선 방안과 향후 연구 방향을 제시하는데 있다. Developing information & communication technology and spreading the internet accelerate globalization of a business. By changing the process and the practice of a commercial transaction we watch the switchover to e-Trade which is a new paradigm in the 21st century. Research on e-Trade has been actively proceeds. The role of e-Trade and information, particularly with the development plan has been made, most recently over the details of the e-Trade deal to do research about the scope and research methodology are discussed, and make another start. The purpose of this paper, the research scope and methodology of e-Trade for a look at recent trends in research degree in e-Trade articles and the analysis and classified as journal for the study of e-Trade improvement is to present and future research directions.
