The JTEL's success case of implementing ERP through ASP is studied in this paper. This paper especially presents the detail processes of implementing ERP through ASP and the advantages of that. Critical success factors in this case study are that pre-prepared ERP template and repetitive prototyping methodology was successfully utilized and that end users involved positively and accepted the standard best-practice processes of the ERP template in this project. These factors reduced ERP training periods and also the whole implementation periods, which made the project time quite short and TCO less. Considering these success factors, ASP method provides the advantages of global e-business IT environment, continuous new IT technologies and flexible response to the business changes to the small and medium firms. Finally, the paper suggests the new direction and possibility for small and medium firms focusing on the core competency and utilizing new system infrastructure through ASP method compared with in-house implementation.

Web-based PMIS (Project Management Information System) has played significant role in construction management processes in Korea. As the use of web-based PMIS increases, regular quality assessment to identify user's requirements is necessary. However, there have been rare research efforts for quality assessment of web-based PMIS. This study aims to assess the quality of web-based PMIS, especially ASP-PMIS (Application Service Provider based PMIS) that is widely used in Korean construction industry. The assessment factors of ASP-PMIS quality were adopted from previous research and empirically confirmed using exploratory factor analysis. ISA (Importance-Satisfaction Analysis), which is a variation of original IPA (Importance-Performance Analysis), were selected for the assessment and analysis method in this research. A total of 253 completed questionnaires, composed of 23 assessment items, were collected from the ASP-PMIS users in Korea (construction managers and constructors), and they were used to analyse the quality of the systems. Some possible contributions of this research are: it introduces a simple and easy-to-use tool for assessing the quality of ASP-PMIS with a set of quality assessment factors that are selected from previous researches and empirically tested; it provides the quality assessment results of ASP-PMIS in Korea so that ASP-PMIS providers in Korea can understand the users' opinion on their systems; it also identified that the urgent factors that require immediate attention to improvement. However, further researches are to be required on the following areas: enhancing the quality assessment factors in terms of their relation to the success of ASP-PMIS and to the users' performance; assessing and analyzing the quality of individual ASP-PMIS; establishing continuous improvement systems institutionally and instrumentally.

위치 기반 광고란 휴대폰, PDA(Personal Digital Assistant), 노트북 PC 등 위치 획득이 가능한 단말의 위치 정보를 이용하여 광고를 하는 것으로 위치 추적이 가능한 단말의 위치 정보를 활용하여 부가정보를 서비스하는 위치 기반 서비스 (LBS, Location Based Services)의 한 종류이다. 최근의 이동 통신 기술의 발달과 휴대폰, PDA 등 모바일 단말의 급속한 확산으로 인하여 LBS 는 유무선 인터넷의 응용 및 그를 이용한 부가 가치 창출에 있어 핵심적인 역할을 할 것이며, 특히 위치 기반 광고는 LBS 시장의 상당 부분을 차지할 것으로 예상되고 있다. 이러한 위치 기반 광고는 광고를 저장하고 관리하는 광고 ASP (Application Service Provider) 플랫폼에서 단말의 위치 정보를 저장 및 관리하는 LBS 플랫폼을 참조하여 위치 및 시간에 따라 광고의 대상이 되는 사용자 목록을 얻고, 해당 사용자에 대하여 단문 메시지 또는 멀티미디어 광고를 제공함으로써 이루어질 수 있다. 본 논문에서는 현재 많이 사용되고 있는 단문 메시지 서비스 (SMS, Short Message Services)를 사용하여 위치 기반 광고를 제공할 수 있는 광고 ASP 플랫폼을 설계한다. 이를 위해 광고 ASP 플랫폼이 제공하여야 하는 기능과 위치 기반 광고의 처리 흐름을 분석한다.

This study suggests the dynamic pricing model which reveals the organic relationship between ASP (Application Service Provider) price and the related factors, using system dynamics methodology. Basically, we applied the law of supply and demand for analyzing price changes. Then, we deducted ASP price, focusing on fixed cost and variable cost. We also researched the customer's buying behavior according to version differentiation policy. In the version policy, we set up the proposition about customer's satisfaction and willingness-to-pay, using option system. As a result, this research designed the simulation model which analyzes the changes of the sales according to version differentiations and customer's willingness-to-pay. Through this research, we can find effective version differentiation strategies. This paper also found that the larger the number of package, the greater the demand and customer's willingness-to-pay. The increase of the number of package causes the increase of the sales. The increase of the sale is not exactly relative to the number of package. Drawing S-curve, the sales was increased. This dynamic pricing model suggests the ground that the ASP price changes based on the existing version differentiation theory and the demand of customers can affect the changes of the sales. We expect that this model suggests a clear standard of ASP pricing by combining real cases.

This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e-marketplace, but also can be applicable to both public and private types of e-marketplaces. This solution is different from the most of the public e-marketplace solutions that their main sources of revenue are transaction commissions or transaction fees through the third-party intermediation. Instead, this solution provides an ASP (Application Service Provider) functionality for direct, disintermediated purchasing and sales-related transactions between suppliers and buyers. With this functionality, suppliers and buyers electronically commerce with each other without the disclosure of their transactions as well as transaction commissions.

The growth of computer resource and network speed has increased requests for the use of remotely located computer systems by connecting through computer networks. This phenomenon has hoisted research activities for application service provision that uses server-based remote computing paradigm. The server-based remote computing paradigm has been developed as the ASP (Application Service Provision) model, which provides remote users through application sharing protocol to application programs. Security requirement such as confidentiality, availability, integrity should be satisfied to provide ASP service using centralized computing system. Existing Telnet or FTP service for a remote computing systems have satisfied security requirement by a simple access control to files and/or data. But windows-based centralized computing system is vulnerable to confidentiality, availability, integrity where many users use the same application program installed in the same computer. In other words, the computing system needs detailed security level for each user different from others, such that only authorized user or group of users can run some specific functional commands for the program. In this paper, we propose windows based centralized computing system that sets security policies for each user for the use of instructions of the application programs, and performs access control to the instructions based on the security policies. The system monitors all user messages which are executed through graphical user interface by the users connecting to the system. Ail Instructions, i.e. messages, for the application program are now passed to authorization process that decides if an Instruction is delivered to the application program based on the pre-defined security polices. This system can be used as security clearance for each user for the shared computing resource as well as shared application programs.

In this study, Automatic Speech Recognition Application System is designed and implemented to realize transformation from present GUI-centered web services to VUI-centered web service. Due to ASP's restriction with web in reusability and portability, in this study, Automatic Speech Recognition Application System with Javabeans Component Architecture is devised and studied. Also the voice web browsing which is able to transfer voice and graphic information simultaneously is studied using Remote AWT(Abstract Windows Toolkit).

대학 정보시스템 분류를 기존의 통합성과 커스터마이징으로 분류하는 것을 현 실정에 맞게 현재의 정보화율을 고려한 어플리케이션 분류를 시도하였다. 전국 대학을 대상으로 실시한 설문조사를 통해 각 시스템의 통합성과 커스터마이징을 조사하여 ‘복잡도’라는 하나의 변수로 설정하였다. 대학에서 정보화가 가능한 모든 시스템에 대해 현재의 정보화율과 복잡도를 고려하여 대학 정보시스템을 분류하였다. 이 분류를 기준으로 ASP 방식을 도입하는 방안(로드맵)을 제시하였다. 분류 모델에 정보화율을 도입함으로써 현재의 상황을 고려한 어플리케이션 분류 모델을 제시하였다. 이 분류 모델은 각 분야에 있어 정보화율에 따른 단계적 ASP 도입 방안 마련에 기초적 기준이 될 것이다.
