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.

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.

With proliferation of computer and wireless network technology, it is common to access Internet through wireless network using mobile device. Ratio of using streaming media out of many applications through Internet is increasing not only in wired network but also in wireless network. Streaming media is much bigger than other contents and requires more network bandwidth and more computing resources. However mobile devices hate relatively poor computing resource and low network bandwidth. If media streaming service is provided for mobile devices without any consideration about network bandwidth and computing power, it is hard for the client to get high qualify service. Since mobile device is supported with very limited energy from the battery, media streaming should be adjusted to varying energy state of mobile device in realtime to ensure complete playback of streaming media. In this paper, we propose DFRC to provide high qualify service to mobile client through wireless network by controlling the number of frames transmitted to client based on computing resource and energy state of mobile device.
