Since the theories of service quality were introduced in Korea, they have been applied to the various organizations, such as hospital, hotel travel agency bank, telecom company, and even retail market. Compared with these areas, however studies on the service qualify in educational institutions have been scarcely conducted. Also, higher educational service challenges user-oriented education system of the 21st century concept of Service quality from the theories of market economy. The purpose of this study is to identify the dimensions of educational and administrative service, and their influence upon the satisfaction and value on service quality, and formulate the service quality model based on the revised quality dimensions using SERVQUAL measuring method, to find out the most influential factors upon the service qualify among these factors. This study also suggests proper measures for improving service quality.

본 논문은 FM방송의 품질측정 방법을 통하여 초단파방송대역의 모노방송 및 스테레오방송 뿐만 아니라 새로운 부가서비스를 대비한 필요주파수대역폭 산정 및 점유주파수대역폭 실측방법을 제시하고자 한다. 이론적인 필요주파수대역폭 산정은 이미 널리 알려진 바와 같이 카슨공식으로 정의된다. 이러한 카슨공식에 근거한 이론적인 필요주파수대역폭 산정과 실측에 의한 점유주파수대역폭을 실측 및 비교 분석함으로써 FM방송의 주파수대역을 효율적으로 이용할 수 있도록 하고자 한다.

The research of image quality estimation standard and the image quality change according to the network traffic load increase at IPTV multicasting service is necessary because the concern of IPTV(Internet Protocol TV) service become active recently. In the research, for finding out the threshold value of network performance elements giving the effect to the image quality according to the network traffic load, we developed S/W to operate the test bed network and make the test scenario through test bed network test and then we expand the test environment scope to the college network and try to measure the image quality change of IPTV multicasting service according to the network traffic load increase at the college network similar to the real IPTV service environment.

Depending on the increase amongst various cloud services, the technology of the Cloud Service Broker (CSB) to find the most appropriate services to meet the needs of cloud service consumers has emerged. In order to advance for cloud services to be used through the CSB, it is important to ensure the quality level that meets the demands of consumers through a negotiation process based on the Service Level Agreement (SLA). However, quality metrics of cloud services are different from each other based on the measurement scale, which represents the quality level, and the calculation for each type of cloud services. Therefore, it is necessary to analyze the variability of the quality of cloud services and establish a SLA model for ensuring and improving the level of quality. In this paper, we analyze the quality metrics for the specific type of cloud services by applying the cross-cutting concept and propose a Virtual SLA (VSLA) meta-model.

Recently the web service area is rapidly growing as the next generation IT paradigm because of increase of concern about SOA(Services-Oriented Architecture) and growth of B2B market. Since a service discovery through UDDI(Universal Description, Discovery and Integration) is limited to a functional requirement, it is not considered an effect on frequency of service using and reliability of mutual relation. That is, a quality as nonfunctional aspect of web service is regarded as important factor for a success between consumer and provider. Therefore, the web service selection method with considering the quality is necessary. This paper suggests the agent-based quality broker architecture and selection process which helps to find a service providing the optimum quality that the consumer needs in a position of service consumer. A theory of agent is accepted widely and suitable for proposed system architecture in the circumstance of distributed and heterogeneous environment like web service. In this paper, we considered the QoS and CoS in the evaluation process to solve the problem of existing researches related to the web service selection and used PROMETHEE(Preference Ranking Organization MeTHod for Enrichment Evaluations) as an evaluation method which is most suitable for the web service selection among MCDM approaches. PROMETHEE has advantages that solve the problem that a pair-wise comparison should be performed again when comparative services are added or deleted. This paper suggested a case study with the service composition scenario in order to verify the selection process. In this case study, the decision making problem was described on the basis of evaluated values for qualities from a consumer's point of view and the defined service level.

최근 모바일에 대한 관심이 늘어나고 있으며, 그 중에서도 핸드폰을 통한 거래는 소액거래 임에도 불구하고 규모가 접점 커지고 있는 실정이다. 그러나 현재 모바일 커머스에 대한 연구는 미비한 실정이다. 특히 모바일 소액결제 시스템에 대한 연구는 거의 없는 실정이다. 따라서 본 연구에서는 모바일 결제시스템 중에서 소액결제를 중심으로 서비스 품질모형을 평가하고자 한다. 이를 위해 본 연구에서는 기존의 서비스품질을 측정하는 지표인 SERVQUAL을 이용하여 이를 평가하고자 한다.

In spite of various studies on the service quality of customer center, the previous studies are mainly focused on the studies on the relationship between customer satisfaction and loyalty, rather than on the evaluation model of service quality. In this study, we reviewed the service quality of customer center factors discussed in previous studies and developed a hierarchical model for measuring customer service quality based on Brady and Cronin's (2001) model. The first level consists of interaction (process) quality, physical environment (system) quality, and outcome quality, and the second level consists of kindness, positiveness, professionalism, systematic, convenience, accessibility, accuracy, promptness, and reliability. In addition, based on the developed hierarchical model, the priority of each factor that customer center users consider important is analyzed by AHP methodology. As a result, the interaction quality was important in the first level, and professionalism, kindness, and accuracy were important in the second level. Such a study can be a guideline for establishing a standard for evaluating the service quality of customer center or for managing more importantly in practice.

The purpose of this study was to investigate the factors affecting of hospital information system quality factors on user satisfaction and service innovation performance in general hospitals. Using 5-point Likert scale, survey was performed on 250 nurses on hospital information system quality, user satisfaction, and service innovation performance. Data were analyzed by t=test, ANOVA, correlation and regression analysis using SPSS WIN 24.0 program. The results showed that significant correlation between service innovation performance and independent variables was seen in system quality (r=0.644, p<.001), information quality (r=0.650, p<.001), service quality (r=0.629, p<0.001) and user satisfaction (r=0.831, p<.001). User satisfaction was a moderating variable between hospital information system quality and service innovation performance with explanatory power of 78.4%. Higher user satisfaction (B=0.557, p<.001) showed positive correlation with greater service innovation performance. Investigating the mediating role of user satisfaction between EMR quality and service innovation performance, it is suggested that importance of system quality, user friendly system support and service.
