This study is about finding factors affecting user experience in China's mobile payment. The recen development of 5G networks and the spread of phones provide the basis for the development of mobile payment, and the development of mobile payment is showing a rapid upward trend. Because of the simplicity and mobility, it is appealing to people, especially young people. Therefore, this study conducted a survey on mobile payment users in 20s and 30s and confirmed the factors affecting the user experience through regression analysis. Unlike previous studies on mobile payment technology, this study focused on user experience and identified factors affecting user experience, so it is expected to be helpful in the development of mobile payment in China.

Complex product systems (CoPs) is a engineering-intensive products with high-ended design technology, which are closely linked with national economic growth and development of social infrastructures. Accordingly, in order to understand the technological evolution of CoPs, it is necessary to identify the macro-environmental drivers surrounding the CoPs and their impact on the technological evolution of the CoPS. Therefore, we investigate the effect of policy, economic and social drivers on the technological evolution of CoPS by implementing the longitudinal case study on nuclear power plant during the periods between 1950 and 2010s. Based on the analysis of various sources of secondary data and primary data through interviews, we found that the technological evolution of nuclear power plant is progressed as "Phase 1: Application research for peaceful utilization of nuclear energy" between 1950s and 1960s, "Phase 2: The first renaissance of nuclear energy" during 1970s, "Phase 3: Enhancement of safety and the catch-up of latecomers in nuclear energy" between 1990s and 2000s, and "Phase 4: Top prioritization of safety and the development of next generation reactors for the second renaissance of nuclear energy" since 2010s. We also found that various kinds of policy, economic and social drivers, such as energy policy, investment in technology development, economic growth and energy demand, social acceptability and environmental concern, have affected the technology evolution of nuclear power plant at each phase. We emphasize the role of macroenvironmental drivers in the technological evolution of CoPS. We also suggest that countries that endeavor to develop CoPs need to utilize those drivers for enhancing competitiveness and sustaining leadership.

전력부문은 전력생산 및 공급과정에서 다양한 환경피해를 유발하는 등 사회적으로 많은 비용을 야기하고 있으나, 생산원가 위주의 현재의 전력가격 책정방식은 환경비용 등의 사회적비용을 제대로 반영하고 있지 못하고 있다. 이는 최적의 발전원구성 및 사회적으로 효율적인 전력공급의 장애 요인이 되고 있다. 주요 발전원에 대한 환경적 가치를 추정하기 위하여 본 연구는 주요 발전원의 전력생산을 수력발전으로 대체하는 것에 대한 지불의사액을 추정하였다. 조건부가치평가법을 적용한 결과, 원자력발전, 석탄화력발전, 가스화력발전 대비 수력발전은 상당히 높은 환경적 가치를 지니고 있는 것으로 나타났다. 따라서, 전력의 도매거래 시 수력발전의 친환경적 가치를 반영하여 향후 적절한 가격을 보장해야 할 필요가 있다.

The rapid diffusion of using internet and technical development becomes a driving force creating and developing the industries based on internet and made up an electronic commerce market which is a new form of business market. The object of this study is the business form between the consumer and the enterprise having a rapid growth nowadays. We classified enterprises' characteristic factors in internet shopping mall into product's characteristic factors on shopping mall, characteristic factors of the system on shopping mall and characteristic factors of the interaction between customers and shopping mall in the internet shopping mall. And then we investigated how these classified characteristic factors on shopping mall could influence on customer loyalty.

경제 제도의 전환기를 맞이하고 있는 중국은 20세기 마지막 20여 년간 빠른 경제 발전을 이루었으며 중국의 도시는 계획경제체제와 중국식 시장경제체제 하에서 독특한 발전 과정을 겪어왔다. 이러한 발전 과정에서 도시 간 물류의 유동과 상호작용을 가장 뚜렷하게 반영할 수 있는 것은 철도망과 철도 운수라고 할 수 있다. 특히 도시간의 장거리 수송은 철도를 위주로 하고 있으며 철도망의 발달은 중국 도시의 형성과 발전에 중요한 요인으로 간주되고 있다. 그러므로 철도망의 구조와 철도 운송 자료는 중국 도시체계의 공간구조를 이해하는데 적절한 지표라고 볼 수 있다.

최근 디지털 기술의 발탈로 방송과 통신의 경계가 허물어지면서 지금까지 없었던 새로운 융합서비스들이 지속적으로 출현하고 있다. 그동안의 방송과 통신은 독자적인 영역을 고집하며 서로 독립적으로 발전해왔다. 하지만, 방송통신융합기술의 발전, 네트워크 성능 향상 그리고 스마트 기기의 폭발적인 증가 등 여러 가지 요인으로 인해 다양한 융합서비스들이 출현 하게 되었으며 빠른 속도로 발전, 확산되고 있다. 논문은 융합서비스의 대표주자인 IPTV 서비스 보안 이슈는 물론 스마트TV, N-Screen, OPEN IPTV 등 IPTV가 발전함에 따라 새롭게 등장하는 융합서비스에 대한 보안위협을 분석하고 그에 대한 대응방안을 제시한다.
