In a recent wireless network environments, dynamic host configuration protocol (BHCP) service is used to assign IP addresses to mobile terminals. In IPv6 networks, it is necessary to introduce the concept of handoff to support a seamless service to mobile terminals. In a general soft handoff technique used by code-division multiple acces (CDMA) communication systems, the powers received to base station are simply compared to determine which base station will handle the signal to and from each mobile termins. However, in IPv6 network, to transmit data-oriented services, it is necessary to support an enhanced soft handoff technique with more security and quality of service. In this paper, we propose a scheme to reduce a signaling process of handoff in IPv6 network. Also, we propose a technique to reduce wasted reservation resources and to guarantee quality of service (QoS) using DHCP.

The current research investigates customers' voluntary participation, using a sample of 446 consumers who visit fashion retail stores. The main focus of this study is to test a social exchange CVP model, including three antecedents of customers' perceived justice through mediators of service satisfaction and brand commitment. In support of the proposed model, I identify fully mediated relationships from interactional justice to the three CVP via service satisfaction and brand commitment and partially mediated relationship from distributive justice to the three CVP through brand commitment. No mediated relationship found for procedural justice neither through service satisfaction nor brand commitment to the CVP behaviors. The results generally support that the significantly indirect effects of perceived justice to the three CVP and satisfaction and commitment are the important mediators in between. The concept of justice can be interpreted in light of the normative value of social exchange relationship.

서비스 블루프린트(Service blueprint)는 새로운 서비스 시스템을 제안하는 단계에서 고객을 중심으로 각 서비스 요소 간의 상호작용을 한 눈에 보여 주고 서비스 전체의 흐름을 파악하기 위해 사용되는 것으로서 온라인 비즈니스가 개발되기 전인 1980년대에 제안된 것이다. 그러나 오늘날의 서비스는 제품 서비스 시스템(PSS)으로 확장되거나, 온라인과 오프라인으로 채널이 다양해져, 기존의 서비스 블루프린트는 이를 표현하기에 불충분하다. 이에 본 연구는 각 비즈니스에 최적화된 서비스 블루프린트 유형을 제안하고자 하였다. 이를 위해 연구에 활용될 PSS사례 137개를 수집한 후 비즈니스 매트릭스를 제작하여 사례를 분류하고, 대표사례를 선정하여 총 두 차례의 실험을 진행하였다. 그 결과 매트릭스에 대응하는 6가지의 서비스 블루프린트 유형인 온라인 서비스형, 온라인 원격지원형, 셀프렌탈형, 온라인 주문형, 전통적 유형, 오프라인 지원형을 도출할 수 있었다. 이후 해당 유형의 적합성을 판단하기 위하여 검증을 진행하여 제안한 서비스 블루프린트의 6가지 유형이 적합함을 확인하였다. 이를 통하여 PSS디자인 또는 개발 시 비즈니스의 특성에 맞게 선택적으로 사용할 수 있음을 입증하였고, 향후 본 연구에서 제안하는 서비스 블루프린트의 유형이 클라이언트에게 효과적으로 전달될 수 있는 템플릿이 되길 바라며 서비스 디자이너나 개발자, 기획자와의 커뮤니케이션에도 효과적으로 사용되길 기대한다.

Recently many companies have increased their investment in IT because they are increasingly interested in taking advantage of IT and they recognized that it was a very important strategic resource that any organization should manage. That means that the members of a company or an organization realized the importance of IT specialists' coordinating and working in partnership with the business employees to ascertain the high quality and productivity through IT services. While the company looks at IT cost reduction, there is a pressure from users for more support and service from IT departments. That means IT service providers have to offer improved service quality at reasonable cost. To solve the contradictory problem, this paper proposes the application of IT service management. If the IT service management is implemented properly, an organization can attain the tangible and intangible results which are profitable and effective. In Korea, studies on IT service management have focused only on getting a certification and development issues, and there are few papers which accomplished empirical studies. From the viewpoint of Resource-based theory, this study reviews the definition of IT service management and its elements. It has demonstrated empirically how IT service management can have an impact on IT service management performance. As a result, IT service management plays a role in adding and improving the practical use and efficiency of IT service management. In conclusion, this study contributes to support and show the critical point of the previous literatures about IT service management and offers the new practical implications for business sectors.
