In order to guarantee system survivability against attacks based on new methodology, we need a solution to recognize important resources for essential services and to adapt the urgent situation properly. In this paper, we present a dynamic resource reallocation scheme which is one of the core technologies for the implementation of intrusion tolerant systems. By means of resource reallocation within a node, this scheme enables the essential services to survive even after the occurrence of a system attack. If the settlement does not work within the node, resource reallocation among nodes takes places, thus the essential services are transferred to another prepared server node. Experimental result obtained on a testbed reveals the validity of the proposed scheme for resource reallocation. This scheme may work together with IDS(Intrusion Detection System) to produce effective responsive mechanism against attacks.

The purpose of this study was to analyze the effect of service convenience on customer satisfaction and reuse intention by 200 passengers using a Korail talk app. The result of the analysis showed that service convenience was positively correlated with satisfaction in Korail customers using the Korail talk app. Also, customer satisfaction with service convenience had a positive effect on reuse intention in these users. However, service convenience was not significantly correlated with customer's reuse intention. The results of this study suggest that it is important for Korail to offer improved service convenience for Korail talk app users consistently in order to improve customer satisfaction and reuse intention by Korail passengers.

The items currently used in museum service evaluations fail to offer satisfactory suggestions that could aid in the improvement of museum services. This study aims to identify and develop items that take into consideration the unique nature of art museum services. This study also identifies factors that determine visitor satisfaction and decisions to revisit with the end of offering methods to improve art museum service. The research conducted was based on an on-site survey of visitors of the Gwangju Art Museum. 223 questionnaires were collected, 211 of which were used in the data analysis. Factor analysis was applied to identify service factors to be considered at art museums. Regression analysis was then applied to estimate the influence of each factor in visitor satisfaction and revisit intention. This study first identifies five service quality factors of art museums: display method, employers, content, facilities, and supplemental programs. Results of the regression analysis showed that content is the most important factor in raising customer satisfaction and revisit intention. Supplemental programs were also significant in raising young and family customer satisfaction. The results also showed that various supplemental services such as education and experiential programs were necessary. Service facilities were also statistically significant factors in customer satisfaction and revisit intention. This study contributes in identifying five factors that could better measure art museum service quality. It also suggests a method to improve museum service quality based on the results of empirical investigations. This information could be of great help to art museum operators and other researchers.

현재 OSGi 프레임워크의 서비스는 로컬 장비에서만 공유할 수 있기 때문에 하나의 장비에 서비스 부하가 집중되는 문제점을 가진다 이와 같은 문제점을 해결하기 위해 확장 서비스 레지스트리를 이용하는 방법이 제안되었지만, 확장 서비스 레지스트리를 재 검색해야 하므로 응답시간이 늦어지는 단점을 가진다. 따라서 본 논문에서는 추가적인 확장 서비스 레지스트리를 재 검색할 필요가 없고, 단지 로컬 서비스 레지스트리만을 검색하여 원격 서비스를 실행할 수 있는 P2P 기반의 RSP 번들을 설계하고 아기 보호를 위한 유비쿼터스 홈 시스템에 실제로 적용하여 구현하였다. 그러므로 본 논문에서 제안한 RSP 번들을 이용하면 하나의 OSGi 프레임워크에 집중될 수 있는 부하를 분산시킬 수 있고, 기존에 개발된 서비스들도 원격 서비스로 재정의하여 다른 OSGi 프레임워크와 서비스를 공유할 수 있게 된다.

It has become a crucial issue for IT service firms how to form positive relationships with their customers in order to retain existing customers and potential customers. To address this issue, many researchers have introduced the concept of consumer relationship proneness(CRP). This present study examines if CRP is related to trust and commitment that enhance the intention to reuse. Using PLS, we analyzed 200 data collected through a survey of global electronic company members experienced IT outsourcing services. As a result, CRP has a defined impact on both trust and commitment, and relationships between trust and commitment, commitment and reuse intention have a positive effect. On the other hand, trust does not affect reuse intention. Based on these results, it presents a discussion for future research and the implications for CRP.
