Family Restaurant is a service business of a kind. The role of service operator is to improve a sales of service goods through maximizing the service value with customer satisfaction at the moment of MOT(moment of truth). Family Restaurant come to the great growth on the face of it. In future, it will place emphasis more and more on not hardware but software including service quality. The purpose of this study, therefore, is to research the effect on service quality of the job satisfaction of Family Restaurant's service staff. Data was collected from the employee who are working at Family Restaurant located in Taegu. The empirical research has been done over 50days from 1April, 2004 to 20May, 2004. In conclusion of empirical analysis, 4 hypotheses were significant among 7 hypotheses suggested in this study. The research showed as follows : First, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on job satisfaction. Second, the personal trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on service quality. Third, the official trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on job satisfaction. Fourth, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed positive influence on service quality. Fifth, the personal trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on service quality. Sixth, the organic trait among the effect factor of job satisfaction perceived by Family Restaurant service staff showed negative influence on service quality. Seventh, the job satisfaction of Family Restaurant service staff showed positive influence on service quality. Besides, the critical points of this study are as follows; First, we designated the subject of research to the employee of Family Restaurant only. Second, multi-situations(time, holiday) which can happen as service was offered, wasn't concerned. Third, as service quality was estimated by general service quality, the research in future should subdivide service quality more. I, finally, applied the pervious researches on job satisfaction and service quality in the employee of Family Restaurant. To extend more this research model in future, the variables like customer satisfaction should be added.

최근 인터넷에서는 Mbone, 인터넷 폰과 같이 End-to-End QoS (Quality of Service) 보장을 요구하는 많은 실시간 멀티미디어 응용들이 출현하고 있다[1]. 인터넷 표준 기구인 IETF (Internet Engineering Task Force)에서는 과거 수년간, 이러한 실시간 멀티미디어 응용들을 지원하기 위한 Integrated Service 구조를 개발하고 자원 예약 프로토콜로서 RSVP (Resource Reservation Protocol)를 개발하였다. 하지만, flow를 기본 단위로 하여 자원을 예약하고 패킷을 처리하는 Integrated Service 모델은 인터넷에 광역적으로 구축되기에는 너무 복잡한 것으로 드러났다. 이에 따라, 큰 규모의 인터넷 전달망에 적용할 경우 scalability 문제를 안고 있는 Integrated Service 모델의 대안 또는 보완책으로, Differentiated Service 구조가 작년부터 IETF에서 활발히 논의되어 왔다. [2,3,4]. 본 논문에서는 Differentiated Service의 구조 및 구성요소의 개념을 살펴보고, RSVP/Integrated Service 구조와 어떻게 공존하여 광역 인터넷에서 End-to-End QoS를 제공할 수 있을지를 고찰한 다음, 향후 기술 발전을 전망한다.

This paper proposes a session control model for the P2P(Peer to Peer) IPTV(Internet Protocol Television) services and presents the IPTV session control procedures based on the proposed model. Since, while public IPTV traffic is usually processed via a separate network, P2P IPTV traffic is processed together with the conventional Internet access traffic, the P2P IPTV control mechanism needs to provide multi-stream processing for the constituent TPS(Triple Play Service) traffic and corresponding QoS(Quality of Service) control functions. Besides, P2P IPTV session control mechanism should provide appropriate multicast control functions in order to support effective transmission of video traffic generated by personal IPTV broadcasters. The P2P IPTV session control model proposed in this paper is designed to be based on the standard SIP(Session Initiation Protocol), IGMP(Internet Group Management Protocol), and COPS(Common Open Policy Service) protocol so that it can contribute to the easy and prompt deployment of inter-operable P2P IPTV platform.

The purpose of this study was to investigate the measurement equivalence and to suggest application ways in teaching aptitude and personality test results for pre-service mathematics teachers between a graduate school of education and a college of education. This study analyzed the scores of the teaching aptitude and personality test of 36 pre-service mathematics teachers enrolled in a graduate school of education and 111 pre-service mathematics teachers in a college of education by performing a multivariate generalizability analysis. The main results were as follows. First, graduate's pre-service mathematics teachers had a higher level of teaching aptitude and personality than that of college's pre-service mathematics teachers based on the total scores. In addition, graduate's pre-service mathematics teachers had higher levels of teaching aptitude and personality than those of college's pre-service mathematics teachers except for a creativity application domain based on the sub-domain scores. Second, cognitive domains were measured more precisely but affective domains were measured less precisely for graduate's pre-service mathematics teachers than for college's pre-service mathematics teachers. Third, regardless of school levels, Cronbach's ${\alpha}$ values, which might be overestimated by applying the classical test theory, were higher than dependability coefficients. Fourth, this study showed a somewhat negative result in ensuring the measurement equivalence for a problem solving exploration domain. However, regardless of school levels, this study indicated that the overall measurement was generally reliable on composite scores. Based on these results, it was confirmed that multivariate generalizability methodologies' approach can be useful for exploring the measurement equivalence issues. Finally, this study suggests how to utilize the results of the test, how to apply a multivariate generalizability analysis for detecting the measurement equivalence, and how to develop future research based on limitations.

The purpose of this study was to identify men's beauty service markets based on socio-cultural appearance attitude and to compare their satisfaction and intention to revisit beauty service. The study was done by survey method. Data of three hundred men aged from 20's to 40's were collected by on-line survey. Descriptive analyses, factor analyses, cluster analyses, Duncan tests, multiple regressions, and path analyses were applied. The results are as follows: First, five factors were found for men's socio-cultural attitude for their appearance. They were high involvement in appearance, social appearance, appearance satisfaction, appearance comparison and low involvement in appearance. Second, cluster analysis based on socio-cultural attitude produced three customer groups such as high involvement, social concern & satisfaction, and low involvement. Third, customer groups showed significant differences in some demographics and some items of service dimensions, which resulted in significant differences in satisfaction, and intention to revisit beauty shop services. A high involvement group was composed of young and unmarried men with more frequent visit to beauty shop service. In general, both the high involvement and the social concern & satisfaction groups showed higher evaluations than the low concern group in some of service items, level of satisfaction, and intention to revisit. In conclusion, attitude on their appearance could be useful factors in segmenting men's beauty service market. Levels and types of beauty shop service should be differentiated among consumer markets.

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.

Ecological restoration is regarded as a major strategy for preventing biodiversity loss and thereby enhancing ecosystem service. This study was performed to evaluate ecosystem service value that the restored ecosystem provides. Ecosystem service was evaluated for provisioning and regulating services. The former service was evaluated by comparing similarities in a viewpoint of floristic composition to the reference site between the restored and the unrestored sites. Species composition of the restored site was found to be more similar to the reference site than that of the unrestored site and thereby restoration practice contributed for enhancing the provisioning service. Regulating service was evaluated based on microclimate control, soil amelioration, and improvement of water holding capacity. The value of ecosystem services in terms of microclimate control, soil amelioration, and improvement of water holding capacity was higher in the restored site than in the unrestored site. In consequence, ecological restoration of coal mine spoils contributed for enhancing the ecosystem service value of the corresponding site and thereby is rewarding the cost invested for restoration.
