This is an exploratory research to examine the high-speed Internet access service's quality There are relatively scanty studies on telecommunication service quality such as the high-speed Internet access service. It has long been considered that service qualify are composed of process quality and outcome quality. Conducting an empirical research, we proposed that traditional outcome quality should be segmented with technical quality and outcome quality. Outcome quality is related to meeting consumer's needs to seek terminal value. In this paper, we explore to diagnose the well-known SERVQUAL's applicability to telecommunication industry and suggest some strategic and practical implications.

본 논문은 인터넷에서 실시간 서비스를 효과적으로 지원하면서도 망의 확장성을 제공하는 방법을 제안하였다. 이를 위해 코어노드에서 각 플로우의 상태 정보를 관리하지 않는 SCORE (Scalable CORE) 네트워크 모델 [1]과 종단간 딜레이 보장이 우수한 QoS (Qualify of Service) 스케줄링 방법중 하나인 WF²Q+ (Worst-case Fair weight Fair Queuing+) [2]에 대해서 기술하고 구현하였다. 이러한 개념을 바탕으로 새로운 망의 구조를 제안하였으며 시뮬레이션을 통한 성능분석을 수행하였다.

In this study, an investigation was done into service qualify factors of infant education Institutes, after which a positive verification was made in the relation of cause and effect between service quality, service value and customer satisfaction. Based on this verification, strategies were presented for plans to improve the service quality of infant education. In addition, identification was made into factors that affect customer satisfaction, re-registration intention and recommendation to others in putting forward service operational strategies for infant education institutes and making a comparative analysis on kindergartens and daycare centers.

Purpose: The aim of this study was to suggest the qualification criteria for the instructors of first aid education for teachers in the School Health Act. Methods: We compared and analyzed the approval provisions for qualifying as first aid educators under the School Health Act, the Emergency Medical Services Act, and prior studies of first aid education. Results: The comparison of the studies demonstrated some key points. First, the first aid education of teachers could be improved through the knowledge of professional instructors. Second, the doctors, emergency nurse practitioners, and emergency medical technicians (EMT) were suitable as specialized first aid instructors. Third, for qualifying as first aid instructor, only the EMTs required more than five years of career. Conclusion: We suggest that all emergency medical service providers qualify to become first aid educators. Additionally, the requirement of EMTs to have more than 5 years of career to qualify as an instructor should be eliminated.

This study intends to examine the effects of CRM on the customer loyalty. Service quality, customer satisfaction, and organizational committment have been tested as mediating factors between the customers' perceived relational efforts and their loyalty. From 236 customers of insurance firms survey data have been collected and analyzed based on the structural equation modeling. The results show that firms' relational efforts have positive impacts on service quality and customer loyalty. Also, this study shows that service quality can play an important mediating role between CRM activities and customer satisfaction as well as organizational commitment, which have shown positive impacts on customer loyalty Consequently, firms need to design their CRM activities paying more attentions to the service qualify attributes, rather than asking too much from the target customers.

There have been academic debates upon which measure is more desirable in measuring service qualify between SERVQUAL and SERVPERF. In addition, Korean air lines industry is rapidly growing due to the increase of Koren family income and globalization. This study tried to contribute to both academic and practical issues. This study compared SERVQUAL and SERVPERF measures to determine which is superior to measure service quality in Korean air lines industry. Data was collected from two airliners' customers of Korea. According to the results of confirmatory factor analyses, regression analyses and analyses of goodness of fit, SERVPERF appears to be better in measuring service quality in Korean air lines industry than SERVQUAL. We suggest that SERVPERF be used to measure service quality in Korean air lines industry.

This study aims to identify service factors that satisfy customers in the internet shopping mail context. The study examines the relationship between service qualify and customer satisfaction, and explores the moderating role of the internet community type (i. e., transaction community group, interest community group and fantasy community group). By analyzing 188 questionnaires, we found that out of the five service quality dimensions, only reliability, tangibility, assurance and responsiveness dimensions have positive effects on customer satisfaction. We also found that there is a significant difference in the relationship between service quality and customer satisfaction by the perceived type of internet community implications of the findings and future research directions are discussed.

In pure P2P environment, it is possible to provide service by using a little real-time information without using accumulated information. But in case of using only a little information that was locally collected, quality of recommendation service can be fallen-off. Therefore, it is necessary to study a method to improve qualify of recommendation service by using users' context information. But because a great volume of users' context information can be recognized in a moment, there can be a scalability problem and there are limitations in supporting differentiated services according to fields and items. In this paper, we solved the scalability problem by clustering context information per each service field and classifying it per each user, using SOM. In addition, we could recommend proper services for users by quantifying the context information of the users belonging to the similar classification to the service requester among classified data and then using collaborative filtering.

최근 컴퓨터 기술과 네트워크 기술의 급속한 발전과 보급으로 유선환경에서뿐만 아니라 무선환경에서도 이동단말기를 이용하여 네트워크에 접속하여 다양한 작업을 수행할 수 있게 되었다. 사용자들이 네트워크를 통해 이용하는 다양한 어플리케이션들 중에 스트리밍 미디어를 이용하는 어플리케이션의 비중이 높아지고 있으며 이는 유선환경뿐만 아니라 무선환경에서도 마찬가지이다. 스트리밍 미디어는 다른 데이타들에 비해 크기가 매우 크고 높은 네트워크 대역폭과 많은 컴퓨팅 자원을 필요로 한다. 스트리밍 미디어 서비스를 낮은 대역폭과 적은 컴퓨팅 자원을 가지는 이동단말기를 통해 이용할 경우 사용자 환경에 맞게 특화된 서비스가 아니라면 안정적인 서비스를 제공받지 못할 것이다. 특히 이동단말기에서는 배터리를 통한 제한된 에너지 환경을 가지고 있으므로 스트리밍 미디어의 재생을 끝까지 보장하기 위해서는 실시간으로 변화되는 에너지에 대하여 적응적으로 스트리밍을 조절하여야 한다. 본 논문에서는 이동단말기를 위하여 스트리밍 미디어 서비스시에 이동단말기의 에너지 상태에 따라 전송되는 프레임의 수를 동적으로 조절하는 DFRC기법을 연구하였다. 제안하는 기법은 적은 컴퓨팅 자원을 사용하면서 동적으로 스트리밍을 조절하므로 사용자들에게 완전한 재생시간을 보장한다.
