In this paper, we draw a security assessment by analyzing possible vulnerabilities of the designated PC service which is supposed for strengthening security of current online identification methods that provide various areas such as the online banking and a game and so on. There is a difference between the designated PC service and online identification methods. Online identification methods authenticate an user by the user's private information or the user's knowledge-based information, though the designated PC service authenticates a hardware-based unique information of the user's PC. For this reason, high task significance services employ with online identification methods and the designated PC service for improving security multiply. Nevertheless, the security assessment of the designated PC service has been absent and possible vulnerabilities of the designated PC service are counterfeiter and falsification when the hardware-based unique-information is extracted on the user's PC and sent an authentication server. Therefore, in this paper, we analyze possible vulnerabilities of the designated PC service and draw the security assessment.

SOA(Service Oriented Architecture) can be a technique to make compassable software from mapping business service to software component. To support effective SOA, it is important that services have to be defined or classified more independently for dynamic and reusable composition. Several methods have been issued but no ways to defined service granularities, service type or service unit. In this paper we introduce 3 level views, service level, service granularity to reuse effectively. And, we suggest service definition guidelines using them.

This paper studios billing mechanisms of value-added telephone services In Korea and major foreign countries. The billing methods of toll-free phone service, voice Information service, one number service, personal number service and calling card service ate compared with each other. The results show that several differences are identified among service providers due to the difference of the regulation, numbering mechanism and underlying networks employed. This paper also provides implications and suggestions to incumbent Korean value-added service providers and regulators

Objective: This paper aims to discuss the case study of Design Dive: Service Design Workshop that was held to improve public services by applying service design methods(February 2011~May 2011). In so doing, it suggests the ways in which public services can be innovated from a design-oriented perspective. Background: As citizens' social and cultural awareness of services is enhanced, there have been emerging needs for innovation of public services. Accordingly, the methods of service design which is to design holistically users' experiences have been considered as an important means to innovate public services. Method: In this regard, the present paper introduces and explores the example of the Design Dive Workshop as a platform whereby service design is achieved. In particular, it analyzes the results of the workshop. Results: The paper presents the results of the workshop and the 10 possible scenarios of public services that were explored in the workshop and suggests models for empowering the workshop participants. Conclusion: Service design is a very effective methodology for providing a new perspective on user-oriented design of public services. The workshop had educational effects on enhancing the participants' awareness of the role of public service design. Application: The Design Dive workshop contributed to improving public services and achieved positive educational results. The methods developed in the workshop can effectively be applied to various occasions on which public services should be improved.

The purpose of this paper is to introduce and test an extension of dichotomous choice contingent valuation(DC-CV) methods of pre-test-market evaluation using the specific case of a cable telev-ision service. Specifically we used a double-bounded DC-CV approach. On the whole respondents accepted the contingent market and were willing to contribute a significant amount on average. This willingness varies according to individual characteristics and concerns about the service. It is concluded that the methods are potentially a useful tool for decision-makers in measuring the po-tential demand for a new cable television service and considering the provision of the service.

Purpose: In the meantime, studies on the measurement methods of service quality have mainly been conducted in views of the service recipients. In this study, we introduce a co-orientation model that compares the perceptions of service provider and recipient and examine the applicability in service quality field. Methods: In this study, we conducted a case study on the specific service called 'National R&D Project Plan Evaluation Service' to examine the applicability of the co-orientation model in the service quality field. Results: We could identify the phenomenon of how service providers and recipients perceive differently about specific services introduced in the case study. This study confirms that it can be used to identify problems in mutually oriented service quality activities and to take practical measures to improve them. As we have seen in this case study, the co-orientation model is expected to be of great help in exploring opportunities for quality improvement in the area of service quality. Conclusion: The service quality co-orientation model allows the service provider to distinguish between what they think of differently with the service recipient and what they have in common, so the service provider will be able to find the agenda of service quality improvement.

Objectives : To determine the relationships among quality, satisfaction, value and purchase intention in health care service. Methods : The data were gathered from out-patients who had used hospital services. They were asked to assess service quality, satisfaction, service value, and purchase intention. A total of 557 usable questionnaires were gathered. The data were analyzed using SAS version 6.12. The analysis methods employed in the study were confirmatory analysis and covariance structural analysis. Results : Service quality exhibited a significant and positive relationship with satisfaction, service value, and purchase intention. Furthermore, satisfaction had a significant and positive relationship with purchase intention. And finally, service value had a significant and positive relationship with both satisfaction and purchase intention. Based on these findings, it is evident that satisfaction was a mediator between service quality and purchase intention. Also service value played a mediating role between service quality and satisfaction. Conclusions : These results suggest that service quality is an antecedent of satisfaction and sonics value, and exerts a stronger influence on purchase intentions than satisfaction and service value do. Thus, managers may need to emphasize service quality in health care.

In a distributed system environment based on a service-oriented architecture, separate systems collaborate to achieve the goals of the entire system by using services provided other systems. A service quality violation from using one service can cause runtime system failure in the environment. The existing self-adaptation methods follow fault tolerance mechanism that responds to a failure after a service quality violation. In other words, these methods are limited to responsive action. Therefore, a service-dependability-case based self-adaptation mechanism is necessary to preserve the dependability of the self-adaptive system. This paper demonstrates that the service-dependability-case based self-adaptation mechanism is better than QoS(quality of service)-based self-adaptation with fault tolerance to preserve the dependability of the self-adaptive system. Additionally, this paper suggests a method to present and analyze service dependability by using GSN(Goal Structuring Notation) which is the existing modeling method for the presentation of assurance cases, an action mechanism adapted using an analysis result of service-dependability-cases, a methods of leveraging the service-dependability-case based self-adaptation mechanism by following the service's life cycle, and the framework architecture including the major components and the interactions between the components in the control loop of the self-adaptation process.

In this paper the authors presents a new method, named FR-SERVQUAL, of evaluating perceived service quality in Public Sectors, using triangle fuzzy numbers and semantic differential scale. By conventional quantification methods, it is not easy to express the notion of a linguistic variables and customers' subjective judgements. In contrast to the conventional PZB methods which express the customers' perception of quality as a function of gap between the expected and perceived service, this paper suggests to use the ratio of the two. Through an application example, this paper shows that the current FR-SERVQUAL approach provides a more realistic way of measuring service quality compared to existing methods.
