21세기에 접어들면서 기업의 경영환경은 급속한 속도로 변화하고 있다. 이러한 급격한 환경변화 속에서 기업이 핵심역량에 집중하고 기업의 경쟁력을 극대화하기 위해 기업의 정보관련 시스템 및 어플리케이션을 아웃소싱하기 위해 사용하는 개념이 ASP 서비스이다. ASP 서비스는 기업내부에 정보시스템 전담 조직을 갖추지 않고서도 각종 소프트웨어를 저렴한 값에 사용할 수 있고, 기업 자체의 전산시스템 및 운영 전담인력이 필요없으며, 하드웨어 및 소프트웨어를 구입할 필요성이 없는 등 여러 가지 이점을 가지고 있어 최근들어 기업들로 하여금 큰 논의와 함께 많은 투자가 이루어지고 있다. 하지만 ASP 서비스의 개념이 비교적 최근에 등장한 개념이기 때문에 관련 연구들이 개념정립이나 도입 의사결정 요인에 관한 연구에 머무르고 있는 실정이다. 이러한 배경하에서 본 연구는 첫째, ASP 서비스에 대한 체계적인 연구를 통해 ASP 서비스의 개념에 대한 명확한 이해를 제공하고, 기업의 정보화 추진 방법으로서 ASP 서비스가 가지는 가능성을 분석해 보고 둘째, 기업이 ASP 서비스를 도입하고 운영함에 있어서 성공적인 수행에 어떠한 요인들이 중요한 영향을 미치는지 살펴보기 위해 개념적인 모형을 도출해 보고자 한다.

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, dis-intermediated 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.

In this paper, we proposed the Failure-Diagnostic Context-awareness Middleware (FDCM) for improving the reliability in the USN application service. The middleware diagnoses the failure occurred in sensors or facilities in the indoor USN application system. The new middleware suggested in this paper consists of DataManagement module, ContextProvider module, Contextlnterpreter module, ServiceProvider module and DataStorage module. By analysing the data obtained by the interaction between modules through the diagnostic algorithm, the FDCM determines the malfunction of sensors and equipment devices. Then we verified the performance of middleware by using simulation. As a result, the FDCM showed the high performance in the large systems that many of the sensors and devices are installed.

This paper presents a state-of-the-art survey in ASP/SaaS Industry and the development strategy of ASP/SaaS business models which are issued as a new software distribution method recently. First of all, SaaS(Software as a Service) is defined as the evolutionary concept of ASP(Application Service Provider) and then the survey results of domestic ASP/SaaS providers and users are presented. In order to cope with recent and rapid If development environment, the development strategy of the ASP/SaaS business models is proposed. The development strategy suggested in the paper is used as a guideline for ASP/SaaS providers to enter into the new ASP/SaaS business and improve their competition.

Application software is delivered to customers as a form of service at cloud environment. A cloud service provider is a marketplace between supply side (application providers) and demand side (customers). Cloud service providers have to validate applications to be included in their service portfolio. Not only performance, security, networking, compliances should be checked but also business contract, authentication should be provided. Organization customers are more sensitive to these validation criteria and process. We study the Internet2 NET+, which is a successful cloud marketplace of applications for research and education organizations. This case study shows us three things : (i) a cloud marketplace's application management process : selection, validation, transition to service, customization of applications (ii) what a cloud marketplace has for its infrastructure like authentication, security, access control etc. (iii) what a cloud marketplace has as its governance structure. This case study will provide informative analysis of Internet2 NET, a profit-making vertical and buyer's marketplace (education industry). And we will get some strategic implications for planning and implementing cloud marketplaces.

Big Data services is composed of Big Data user, Big Data service provider, and Big Data application provider. And it is possible to extend the service to interplay-reciprocal actions among three subjects such as providing, being provided, connecting, being connected, and so on. In this paper, we propose an ecosystems of Big Data and a framework of its service.

This study applies the Analytic Hierarchy Process (AHP) to evaluate service quality of Third-Party Logistics (3PL) providers. For this, 3PL service quality is conceptualized and measured using SERVQUAL's five dimensions such as tangibles, reliability, responsiveness, assurance and empathy. Then, the AHP method is applied to determining the relative importance of five service quality dimensions and eventually selecting the best 3PL provider. Finally, this study conducts an empirical case study on four companies providing 3PL services in Korea to demonstrate the basic idea suggested in this paper. The results obtained in the present study indicate that responsiveness to customers is the most important factor perceived by 3PL customers and 3PL C is the best 3PL provider according to the overall service quality scores. In contrast to some previous researches, this study examined issues of service quality from the perspective of 3PL customers as opposed to the perspective of 3PL providers. In order for this study to be more complete, future research is needed in establishing a set of metrics to quantify each dimension of 3PL service quality proposed.

In this paper, we propose a method for transmitting SMS(Short Message Service) for VoIP(Voice over IP) service supporting multi-protocol. The multi-protocol VoIP under consideration are generally composed of H.323, SIP and MGCP and Most ITSPs(Internet Telephony Service Provider) provide VoIP service with H.323 and SIP now. SMS is killer application in mobile telecom service and many people of various field use that service. For example, user can send many SMS messages and substitute e-mail. Also SMS can be provided with various internet application. Ahn, legacy phone of KT, can use SMS. Therefore VoIP phone also can be required with the same requirement. With the multi-protocol VoIP we will propose several methods sending efficiently SMS. To show the validity of the proposed method some examples are given in which the results can be expected by intuitive observation.

With the development of wireless network technologies, mobile users may use various networks easily and expect more advanced services. On the other hand, it may bring on some problems with network resource management that should lead the service provider to improve the current service quality and manage the network resource efficiently. This paper proposes the optimized radio resource management (RRM) scheme that integrates the Grey Relational Analysis (GRA) and game theory. The first applies the GRA to determine the Grey Relation Coefficient (GRC) factors that represent the network preference, and the network provider then selects the requested service that provide maximum payoff through Nash Equilibrium. Six requested services that have one application service among four different types of service classes were considered and the game was played repeatedly. In WiMAX, WLAN 1 and WLAN 2 game, the maximum payoff of each players was 93, 90.6 and 92.8 respectively. The experimental results show that every requested service can be selected by the network provider. Consequently, the proposed radio resource management mechanism is more effective in heterogeneous wireless networks.
