It is estimated that the world market size of the outsourcing of information system will be 780 billions in 2004, and that of ASP, one of outsourcing markets, will be 24 billions in 2005. The domestic outsourcing market also has 6 times grown in 2001 compared to the size in 2000. However, there have been only a few systematic researches about information system outsourcing and ASP in Korea. Though the importance of ASP has been recognized, no business model has been examined. So, this research was done to survey the outsourcing of information system and the meaning/present status of ASP, and to consider several factors to successfully introduce this service to companies. Especially, this research focused on ASP.

While the demand for ASP(Application Service Provider) focused on small and medium enterprises who are fully aware of needs of ICT readiness has been increasing, those who consider to adopt ASP are wondering whether their performance would be actually successful if they did. These concerns can be an important standard of judgement, when introducing new information systems, by analyzing ROI(Return on Investment) on the current enterprises. Therefore, to review the feasibility of investing IT and measuring the performance, this study suggests a framework for ROI analysis which estimates IT investment performance, through multi-criteria approach on both financial performance index and non-financial one. We applied methodology on ASP-based IT investment performance evaluation to sample manufacturing companies under 50 employees and deduced the main implications to be considered when introducing the system.

정보기술의 관점에서, 기업 가치사슬상의 내/외부적 협력을 협력을 구현하는 방법으로ASP(Application Service Provider)를 통한 IT 아웃소싱(outsourcing)이 차세대 가상기업의 핵심 요소가 될 것으로 전망된다. 이러한 맥락에서 본 연구는 ASP 의 서비스 제공에 관한 성능을 향상시킬 수 있는 방법으로, HoQ와 AHP를 통합한 방법론을 제공한다. 그리고 이러한 통합모형을 적용하여 고객만족의 관점에서 ASP 서비스 개선을 위한 핵심 기능요소(functional elements)를 찾아 내었다. ASP 서비스의 지속적인 개선은 점차 심화되어 가는 경쟁에서 생존하기 위해 최우선적으로 중요한데, 본 연구의 HoQ/AHP 통합모형은 서비스 개선을 전략적으로 구현하는 좋은 도구가 될 것이다.

In this monograph, we developed a Remote Courseware Management System so we can more easily cultivate a courseware with various multimedia applications through an easy interface with the internt. In the view of Developer of view, we could develop RCMS rapidly using the application of ASP.NET and have tried to adapt ourself to the future environment using it. ASP.NET provides much richer event programming model than ASP and event processor which are executed on Server. In the view of User, they can used the Internet service with equipment that they want at any place and any time. To control any kinds of courseware for Administrator and Users, we offered a variety of Multimedia applications and an easy interface and built a new style of web courseware.

새로운 패러다임은 소유에서 접근으로 변모하고 있으며, IT분야에서는 특히 소유보다는 접근과 아웃소싱이라는 새로운경영 패러다임이 형성되고 있다. ASP(Application Service Provider)는 소프트웨어의 구입보다는소프트웨어의 사용권을 취득하고 이를 네트워크를 통해 서비스하는 비지니스 모델이 도입되고 있다. 즉, 일종의 소프트웨어 임대사업이라고 할 수 있는 ASP는 기본적으로 패키지 프로그램을 구입하는 것보다 저렴하게 사용할 수 있는 장점이 있다.

In this paper, to improve bandwidth of microstrip antenna, we discussed the patch structure using Aperture Stacked Patch. To provid PCS service and IMT-2000 service simultaneous, a microstrip patch antenna needs impedance bandwidth of 22%. But typical microstrip patch antennas have impedance bandwidth of 3∼6%. To analyze characteristics of microstrip pach antenna, we used Ensemble of commercial software. The microsrtip patch antenna was designed and fabricated, tuned. We get following results; 650MHz(33%) of impedance bandwidth for VSWR 1.5. The measured gain of ASP microstrip antenna is 6.94dBi.

Recently, software distribution method, along with advent of era of Web 2.0, is rapidly evolving from ASP(Application Service Provider) method into SaaS(Soft as a Service) method due to development in concepts and technologies including SOA(Service Oriented Architecture) Web Service, On Demand and Component. Determining factor in market competitiveness of newly emerging SaaS business model will be analyzed by focusing on Group-Wares, POS(Point of Sale) System, CRM(Customer Relationship Management) and ERP(Enterprise Resource Planning), which are the most representative SaaS business models in Korea. It is anticipated that the outcome of analysis of determining factors for market competitiveness for each of the main SaaS Business Models acquired through questionnaire survey can be utilized as important benchmarking material in setting the direction of cultivating SaaS market by the government as well as new entries into SaaS market.

Small and medium-sized companies (SMEs) face a number of different kinds of barriers to adopt information technology, including the lack of information, limited financial and technical resources, and absence of the well-trained work force in the realm of information technology. But application service provider (ASP)enables these SMEs to informatize. This paper is focused on studying the cases of the adoption and use of the ASP-based ERP systems that 7 SME shad adopted. The factors that influence the adoption and use of SMEs' ASP-based ERP systems are divided into the user companies that adopted the systems, the systems vendors, and environment. From the viewpoint of the user company, the successful adoption and use of the systems is significantly influenced by the clear motive of adopting the systems, the financial readiness, and the strong intention of CEO for pushing ahead with e-Business. From the systems vendor, it is influenced by the technical expertise of the vendor, the knowledge of the user company, and the experience of the systems development. From the perspective of environment, it is influenced by the push from the players in the value chains. The companies that had adopted the ASP-based ERP systems and that had extended the level of systems use had the benefits through reducing the cost, improving the internal business process, and achieving the learning and growth of the organization.
