This paper proposes a quality measurement model for video phone service over IP environment. Proposed model enhances conventional E-Model by using quality analysis and this model is suitable for ubiquitous environment. This research measures video phone quality by applying bust packet loss and recency effect. It uses delay and recency effect for compensating actual quality and recognized quality of user using NR and UR factor. Simulation results show that this model can provide more precise results than conventional model by considering recency effect of video phone service quality measurement model.

The purpose of this study is to analyze the impact of quality and satisfaction of mobile telecommunication service on the quality data sharing for mobile telecommunication service. Based on the theory of reasoned action(TRA), we proposed a research model that (1) service qualities significantly influence the service satisfaction and the attitude towards information sharing, (2) the attitude towards information sharing mediates between service satisfaction and the intention of information sharing, and (3) the intention of information sharing is affected by the service satisfaction and the attitude towards information sharing. Empirical analysis of mobile service users showed that the data quality of mobile communication services had a greater impact on satisfaction than voice quality. The service satisfaction had a positive effect on attitude towards information sharing and the intention of information sharing. Also, the attitude towards information sharing had a positive impact on the intention of information sharing. Based on this empirical study, we proposed a crowdsourcing as an alternative when quality data of mobile telecommunication service should be collected to improve telecommunication policy because by using collective intelligence of the crowdsourcing the government can gather more accurate and diverse data on mobile telecommunication service.

In this study of the domestic high school and middle school students to use the online education-website to measure the quality of service between SERVPERF model and the KS-SQI model fits which were analyzed further. Analysis using AMOS 7, SERVPERF for measuring quality of service reliability, responsiveness, assurance, empathy and tangibility, was a measurement model. KS-SQI for primary needs fulfillment, unexpected benefit were performance dimensions, reliability, individual empathy, positive assistance, accessibility and media tangibility, consist of process dimension was measured. In comparison of two models, the KS-SQI model on a path analysis showed better in terms of model fit indexes.

IPTV(Internet Protocol Television) is an innovation technology to lead the new media age. Internet protocol television (IPTV) is a next generation television converged with the Internet which are delivered portal services such as information search, games, movies, home shopping and banking. Generally, service quality affects to adopt or use these technologies. Quality of experience (QoE) is more issue to be considered than service quality because of the technological restriction and limitation that IPTV is accessed by the Internet. The QoE is defined as the cognitive and experienced quality measured with users through an experiment and is conceptually related to service quality. The objective of this paper is to suggest a methodology to measure the QoE of IPTV using a user testing. We find significant factors affecting QoE of IPTV through an exploratory study and measure QoE scores. We found the nine factors of graphics, picture, accuracy, access method, quality of contents, usability, security, and performance important for QoE. The QoE scores of picture, graphics, and quality of contents gained over the average score, but the overall score for IPTV service providers was not high and the QoE needs to be improved.

Marina industry is growing as a higher value-added business. This study aims to develop a tool that measures marina service quality from marina users' perspective. As the result of empirical analysis, five of marina service quality aspects including physical facilities, support services, activity programs, employees' attitude, and safety were drawn. In addition, 20 measurement items whose reliability and validity were verified were suggested. The scale developed by this study is not only an important tool to measure marina service quality but also contributes to marina service quality control, and seem, to provide useful information for establishing marketing strategies.

This paper aims to develop an evaluation model for library mobile services in terms of service quality. First, a literature review of the service quality evaluation model and the mobile library service evaluation was conducted. Then, based on the analysis, the evaluation model consisting of 4 quality dimensions, 10 quality factors, 39 quality measurement items was developed. Delphi method was applied to verify the validity of the model. Finally, a final model consisting of 4 quality dimensions, 9 quality factors, and 37 quality measurement items was derived. The evaluation model proposed in this study can be used as a measure of library mobile service quality and can be used as a guideline for improvement of library mobile service.

The purpose of this study is to review recent studies on the service quality evaluation of digital libraries and to derive from research trends and several suggestions. Specifically, this paper compared and analyzed recent literatures on e-service quality evaluation of digital libraries in Korea with regard to service quality evaluation models and measure methodologies. Finally, this study offered two important suggestions. The one is the necessity of developing a standardized service quality evaluation model for digital libraries which is customized in korean environment and the other is establishment of development guideline of service quality evaluation for digital libraries.

이용자의 정보요구 변화와 이용자 중심의 서비스로 전환 그리고 도서관의 심화된 경쟁 등의 도서관을 둘러싼 환경의 변화는 이용자 기대의 변화와 도서관 경영이 변화를 가져왔다. 따라서 이용자에 대한 관심의 증가와 그들의 요구를 파악하기 위한 노력이 도서관 경영에 필요하게 되었으며, 도서관 품질 평가에 있어 수치적인 측면에서 탈피하여 고객 중심의 품질 평가로의 전환이 필요하게 되었다. 본 연구는 서비스 품질 측정에 관한 다수 이론들과 모형을 정리하여 도서관 서비스 품질을 측정하는 새로운 도구를 제시해 보고자 한다.

This paper aims to describe the measurement and improvement of academic library service quality by ISA (Importance-Satisfaction Analysis). This research established service quality model on based LibQUAL+(R). It consisted of 18 items that formed three dimensions, affect of service quality, information control quality, and library as place quality. To execute this research, the service quality according the users' importance and satisfaction of library service is measured through Gaps model and ISA. The data for this case study was collected through the survey conducted the users of the H University library. By applying SPSS 17.0 and Excel 2007, the final 113 surveys were used for analysis.
