The purpose of this article was to review the basic concept of the SERVQUAL scale and to evaluate its usefulness in health care settings. The SERVQUAL scale was developed by Parasuraman et al. in 1988. Its purpose was to provide an instrument for measuring the quality of service that would apply across a broad range of services with minor modifications in the scale. The SERVQUAL scale is based on gap theory, which indicates the difference between consumers' expectations and their assessment of the actual performance of a specific firm. It has five dimensions to define service quality. These dimensions include: (1) tangibles' (2) reliability' (3) responsiveness' (4) assurance' (5) empathy. While the SERVQUAL scale has been tested in a number of health care settings. the findings have been mixed. So. health care marketers should be cautious in their use of the SERVQUAL scale. However, it is rare to find instruments that are as well validated as SERVQUAL appears to be. As well the SERVQUAL scale provides valuable information about the quality of health care service.

The era of express train in Korea has come since April in 2004. The KTX(Korea Train Express) which has introduced the technology of TGV of France is regraded as good as the ICE of Germany or Shinkansen of Japanese in its hardware aspects. However there are still many things to be improved in its software aspects such as the quality of services, since the new express railway system is in the early beginning stage. To improve the quality of services, we should first measure and analyze the current level of the service quality. Using SERVQUAL model, the service level of KTX is measured and analyzed in this paper. Issues on how to improve the service quality are discussed based on the measurement and analysis.

The Korea-US dispute on telecom standards has shown the inability of existing trade rules that can be applicable to standardization policy in telecom services sector. It has entailed plenty of dissenting but unsolved trade issues, including legal jurisdiction over technical standards on telecom services and their compatibility with WTO agreements. Question remains how US will cope with this tricky trade puzzle. This paper points out that Korea-US negotiations on telecom standards have provided US with a momentum to think seriously over the necessity of further rule-setting on telecom standards, and FTAs are the rescue train for US to ride on for that purpose. That is to say, US is taking advantage of FTA as a means to promote its national commercial goals by creating trade rules, which seek to deprive its trading partners of regulatory autonomy in telecom standardization. Based upon the research output, it is very important for Korean government in the upcoming Korea-US FTA negotiations to ensure facilitating public policy objectives in telecom standardization as possible as it can, and not to adopt the provision of international standards in the existing US' FTAs.

Recently, SaaS(Software as a Service) as a new type of information systems has become popular. Many information systems practitioners and academics, consequently, pay their attention to SaaS. However, there are very few empirical studies on SaaS success factors because of its short adoption history. This study, therefore, tries to identify a variety of success factors of its adoption and examines how these factors affect organizational performance using an exploratory approach. For this purpose, this study collects data from 132 Korean companies and analyzes the relationship between success factors and organizational performance. Our results are likely to help provide useful guidelines for the successful SaaS adoption.

The company cannot optimize its computing environment just with individual solutions such as ERP(enterprise resource planning), SCM(supply chain management), CRM(customer relationship management), and KM(knowledge management). EAI(enterprise application integration) has emerged as an alternative that can optimize computing environment of the company through integrating such solutions and systems of distributed computing and mainframe environment. This paper reports the case study of Deakyo Co. in successfully implementing EAI. It describes project goal, project organization, project plan, the implemented EAI configuration and its features, the EAI effectiveness to the firm, and the critical success factors of the EAI project. This case study is thought to be useful as a practical guideline in carrying out EAI project of the company and to provide significant basis for constructing the theoretical framework of EAI project methodology.

It is essential for companies to manage massive data for dealing with large volume of transactions and customers' needs. To this end, the companies have operated data warehouse with many complex tools for data gathering and reporting to the end-users. However, the data from the heterogeneous tools at the various sources cannot be exchanged because of the different interfaces. Therefore, the data cannot be controlled with integrated manner, and furthermore the companies do not focus the quality of data resulting in the data quality problem. Thus, this study suggests how to manage massive data with a metadata. In particular, we investigate current status of metadata management, its appliance, and perspectives. The contribution of this research is to apply the metadata management system to the real world and to suggest its management procedure.

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.

This paper addresses the issue of workflow on Grid and P2P, and proposes a layered workflow architecture and its related workflow models that are used for not only distributing workflows' information onto Grid or P2P resources but also scheduling the enactment of workflows. Especially, the most critical rationale of this paper is on the fact that the nature of Grid computing environment is fitted very well into building a platform for the maximally parallel and very large scale workflows that are frequently found in very large scale enterprises. The layered architecture proposed in this paper, which we call Enterprise Workflow Grid Architecture, is targeting on maximizing the usability of computing facilities in the enterprise as well as the scalability of its underlined workflow management system in coping with massively parallel and very large scale workflow applications.

Green's relations are five equivalence relations that characterize the elements of a semigroup in terms of the principal ideals. The J relation is one of Green's relations. Although there are known algorithms that can compute Green relations, they are not useful for finding all J relations in the semigroup of all $n{\times}n$ Boolean matrices. Its computation requires multiplication of three Boolean matrices for each of all possible triples of $n{\times}n$ Boolean matrices. The size of the semigroup of all $n{\times}n$ Boolean matrices grows exponentially as n increases. It is easy to see that it involves exponential time complexity. The computation of J relations over the $5{\times}5$ Boolean matrix is left an unsolved problem. The paper shows theorems that can reduce the computation time, discusses an algorithm for efficient J relation computation whose design reflects those theorems and gives its execution results.
