The convergence of telecommunications and broadcasting is representative of many innovative technologies in the digital environment. It has recently been emphasized as an alternative solution to overcome the on-going saturation of the telecommunications and broadcasting markets. Despite this effort, however, growth of the market and its related services cannot reach prior expectations due to lack of understanding on the real user-end. Telecommunications technology used to serve its instrumental purpose and broadcasting services usually support entertainment functions which in themselves have an inherent value. Our research questions what factors influence users' attitude and decision-making when it comes to using telecommunications-broadcasting convergence services. The research model of this paper proposes intrinsic motivator focusing on hedonic value, extrinsic motivator having utilitarian values, and perceived control as internal and external conditions. To verify our model empirically, we selected the DMB technology which is a good example of distinctive telecommunications-broadcasting convergence service.

Recently, there has been a tendency to lead the private sector in the launch vehicle market, and as the market has become saturated, efforts are being made to reduce the launch cost. Advanced countries in space development have promoted manned long-range space exploration plans. As oxygen/methane is more efficient, lower cost, and eco-friendly than typical propellants, and can be produced locally on an alien planet, it is the most suitable next-generation propellant to meet this trend. Now methane engine development is accelerating due to changes in international conditions and corporate environment. It is also expected to develop a methane engine in order to survive in this global trend and to keep up with the launch vehicle market in the future.

Overseas Expansion is essential to expand domestic geospatial industries in a state of saturation. But current overseas expansion method has be limited to expand global market. Inter-industries convergence strategies may be most resonable alternative to expand global market through raising expansion possibility to developing countries with ODA funds and to developed countries with converging global competitive industries. This research analyzed the industry to develop a suitable way fusion between these industries. As a result, easiness of convergence, confidentiality of information, complementarity of poor infrastructure, responsiveness of various demands and sustainability of system are needed to successful convergence on multiple industries. This convergence framework is consists of geospatial convergence common framework based on cloud computing, inter-industries convergence model and institutional supporting system for overseas expansion.

This paper deals with survival facility location problem(SFLP) that the store with less of demand threshold level is closed result from another new establishment of store in the same kind of comparative firms have a monopoly market. We will be faced with a difficult problem when a new establishment stores in market saturation that the closed stores more than opening stores. Serra et al. proposes recursive heuristic concentration algorithm, and Han et al. suggests maximum insurance of customer location. But the drawback of these algorithms is a recursively computation for many locations. This paper get the solution from only neighborhood search of comparative firm's stores that can be maximum customers and closed comparative firm's store, and the location with minimum customer exchange to the location that can be closed the comparative firm's store with maximum customer. The advantage of this algorithm is to get the solution using a MS-Excel.

본 연구에서는 소매업 변동에 관한 제 이론 검토와 입지 이론에서는 수요이론과 공급 이론에 대하여 두 이론이 부분적 적정성을 갖는 한편 양 이론이 동시적 고찰하지 못함에 따라 소매업태 입지 관련 적용에는 한계가 있다는 점을 지적하였다. 체인오퍼레이션의 의사결정 프로세스 분석을 통하여 새로운 체인 입지와 관련 문제점으로 공간 경쟁 효과와 시스템에 대한 매력효과를 검토하여 장단점을 복합적으로 반영하여 신규 출점 입지 의사결정을 하여야 한다는 것이다. 기존 선진 소매기업의 의사결정 기법을 통하여 국내 기업의 입지 의사결정에 기초 자료로 제공하고 실증 연구로서는 포화기 단계에 들어선 한국 할인점 시장(인천지역 T사의 기 출점)을 대상으로 의사결정단계의 일반 기준과 세부 기준을 제시를 통하여 AHP(Analytic Hierarchy Process) 계층 분석 방법으로 중요도를 평가하였다.

This paper investigates the relationship between the passenger car demand and business activities in the OECD. The positively linear relationships changed suddenly since 1990 and the reason was thought to be the polarized economic development of USA and Japan. The cases of other countries supports this conclusion. According to the conclusion, we modeled and estimated the car demand function of Korea.

The aim of this study is to shed light on the importance of female drivers, study their characteristics and needs, and create automobile designs in accordance with the study. The power of female consumers is greatly increasing in a modern society, To the extent that women became the core consumers. Companies are now turning their attention to female consumers in order to survive the fierce competition in the saturated markets. Moreover, it is becoming imperative for companies to actively develop products and services in female perspectives to meet the diversified needs of consumers. It is forecasted that vigorous research, analysis and understanding of the unique culture of women will be increasingly important now that women are emerging as core consumers. Only the companies that makes such efforts consistently can dominate the market. The automobile industry is not an exception. The world's major automobile companies including Volvo and Ford Motor Co. are keenly focusing on automobile exterior and interior designs for women. Korean companies are also designing cars that cater to women, starting with Lanos and Juliet of Daewoo Motors in 1998, yet specific and systematic research on the subject has not been made. This study aims to emphasize the power of female users, make a research and analysis on their needs and characteristics, and suggest car interior designs that cater to them.
