The KOREASAT satellite, the first Korean commercial communication and broadcasting satellite, has been launched in August 1995, and has started to provide the communication and preliminary broadcasting services, respectively, in March and July 1996. In this paper the network configurations and characteristics of the services which the KOREASAT satellite provides are described. The services, which are provided by the KOREASAT satellite with its twelve communication and four broadcasting transponders, are the direct broadcasting service, the video relay service including the TVRO, SNG and TV/CATV program distribution, the company-wide communication service including VSAT and TSAT, and the other services with the digital line, trunk relay, telephone line, mobile data, music broadcasting services, etc. A communication transponder has the 36MHz bandwidth and 14W output power, and a broadcasting transponder has the 27MHz bandwidth and 12OW output power.

In case of accidents at the line of Seoul-Pusan high speed railway, high speed train should be operated with making a detour by using existing Seoul-Pusan railroad. For Dae-jeon$\sim$Dae-Gu section which has fragile structures, following points are investigated. In operating existing train, train running time is analyzed by the case of only high speed train being in service and the case of high speed train being in service on condition that existing train is operated. Also the possibility about operation on present train headway and train headway that is applicable to operation and vocational problems would be examined.

오늘날 사람들은 기존 IT서비스 보다 더 개선된 새로운 IT서비스가 등장하게 되면서 IT서비스의 전환을 고민하게 되고, IT서비스를 제공하는 기업들도 고객유지 또는 고객확보를 위한 전략을 개발하고 있다. 온라인과 오프라인 환경 모두에서 서비스 전환의도에 대한 연구는 매우 중요하게 다루어지고 있다. 본 논문에서는 사용자의 IT서비스 전환의도에 영향을 미치는 요인들과 이들의 영향정도를 실증적으로 분석하고자 한다. 서비스 전환의도에 영향을 주는 요인들 간의 직접적인 관계뿐만 아니라, 개인적 특성인 습관과 대안 IT서비스의 매력이 현재 IT서비스 만족을 통해서 IT서비스 전환의도에 영향을 주는 관계, 전환비용 지각 크기에 따라 IT서비스 전환의도에 다르게 영향을 주는 관계를 포함한 연구모형을 설계하였다. 설계한 연구모형은 구조방정식모형과 다중집단분석을 사용하여 실증하였다. 검증결과는 IT서비스 전환의도에 습관과 기존 IT서비스 만족은 유의한 영향을 미치나 대안 IT서비스 매력은 그렇지 않고 기존 IT서비스 만족을 경유하여 전환의도에 영향을 주는 것을 보여 주고 있다. 또한, 전환비용이 클수록 습관이 전환의도에 주는 영향력이 강한 것을 확인할 수 있다.

The advantages of implementing a virtual channel can be derived from the notion of the 'death of distance' that would result from electronic commerce. According to this view, the internet was going to make distance irrelevant, in that firms would no longer need to establish a physical presence in a geographical location in order to do business there. However, on-line firms selling physical products could take advantages of presence in the related off-line(brick and mortar) industrial area. This paper developed a conceptual framework that highlights the various types of synergies by location on-line businesses in the related off-line industrial area. Using data from 96 on-line ventures selling physical products, factor analysis was used to figuring out six synergies including improved customer trust, value-added service, cost savings, personnel and organizational efficiency, sharing products and customer information, relationship with suppliers, and relationship with local government. The six empirically derived critical synergy factors were then used to examine how they improve performance of the on-line ventures measured by Balanced Scorecard(BSC). According to lthe results, we concluded that the on-line firms selling physical products can take advantages of presence in the related off-line industrial area.

The general description concerning the multi-line systems with the switching rules have been presented by Ahn. In this paper we derive some steady state probabilities for three mainly different kinds of systems. We assume that all of the systems are to have poisson input with the finite mean $1/\lambda$ and two servers with the negative exponentional service distribution where each has its own mean $1/u_i$. The notations follow the paper (Ahn, 1979).

Business organizations today enjoy unprecedented connectivity over the Internet that directly affects their bottom line and their top line. Connectivity increases productivity and reduces cost of operations. It eliminates barriers resulting from distance and integrates the world. Nevertheless, businesses today face a challenging trade-off between securing their corporate assets and leveraging this ubiquitous connectivity to improve their operations. (omitted)

Recently, financial service industry of Korea started to pay attention to private banking targeting to the rich. However, as the advanced foreign competitors have entered the market, strategic approaches are needed focusing on the general rich rather than the exceptional VIPs. In this paper, we use QFD to provide marketing strategies for Korean financial service providers. Our finding is that ‘intangible service provided by private banker’ and ‘off-line sales’ have marketing priority and ‘investment management’ and ‘value-added service’ follow.
