Assessing service quality and satisfaction is the essential part of service science. In this study, for G2B electronic commerce service composed of information systems and human resources, a composite research model for exploring factors of service quality satisfaction is proposed. The proposed model uses SERVQUAL's five quality dimensions as independent antecedent factors and usefulness and ease-of-use of the technology acceptance model as mediating factors. A case of a G2B purchase service is empirically studied using the proposed model. The result shows that the proposed composite model is good and appropriate for explaining the characteristics of G2B services.

As the easy payment service is popularized and the competition in the service market is fierce, research on factors affecting users' continuous use of the easy payment service is becoming increasingly important. However, in the existing studies, the discussion of the continuous intention to use the consumer's simple payment service has not been sufficiently conducted. Existing research remains on the way of listing technology and consumer characteristics. To bridge this research gap, this study aims to integrate and modify ECM and UTAUT to consider factors influencing the continuous use of easy payment services. The user's expectations and the confirmation were considered as important factors to decide. For empirical analysis, a survey was conducted for 236 users who had experience with domestic easy payment service. As a result, it was verified that confirmation, performance expectancy, effort expectancy, social influence, and habit in regard to easy payment services are important for continuous use intention. Through this study, it is expected that the consumer's technology acceptance mechanism on the continuous use of simple payment will be grasped in more detail to develop academic discussions in the field. Implications from the results as well as limitations of the study are presented.

The objective of this study is to test Parasurman, Zeithaml & Berry(1985)'s service quality gap analysis model, and to confirm reliability and to confirm reliability and validity of the model. The reliability of the model is adopted, but the validity must be retested in the further study. In the results of the gap analysis model, the correlation between consumer expectations and management perceptions of consumer expectations(gap1) was not accepted. The correlation between management perceptions of consumer expectations and service quality specifications(gap2), the correlation between service quality specifications and the service actually delivered(gap3), and the correlation between services delivered and services promised to consumers(gap4) were accepted. To improve domestic telecommunication service quality, practical guides such as standardization of job roles, cooperation among customer-contact persons, communication between managers and employees, evaluation programs for employee's improvement of service quality, appropriate supports for customer-contact persons were suggested. For generalizing the gap model, additional studies under the different contexts and industries will be needed.

Differentiated Service is an IP QoS ensuring method based on packet marking that allows packets to be prioritized according to user requirements. During the time of congestion, more low priority packets are dropped than high priority packets. Different policy models are used to determine how to mark the packet. This paper investigated the performance of Differentiated Service using time sliding window with 3 color marking (TSW3CM). Simulation results using NS-2 showed that Differentiated Service can provide the quality of service requirements.

This dissertation investigated the evaluation model of IT Service quality: concentrated on the quality components in mobile communication service. Today, mobile communication service is changing dramatically. The first and second generation's mobile communication services were designed for voice and SMS(Short Message Service). However, while the mobile communication industry grows, the mobile technology made more services available for customers. Customers' changing needs brought a new opportunities to the market. Now, mobile communication service is facing a new era as multi-functioning, multimedia service, and high speed data transfer service are being introduced. There has been a lot of theoretical literature on service quality components of mobile communication, but most of the literature was focused on the voice service and SMS(1st and 2nd generation). As mobile communication service evolves, the components may have to be altered or rebuilt. To identify which service quality components ought to be utilized, prior studies on service quality components, service quality, and customer satisfaction were reviewed. Also, a survey was conducted on the various aspects of mobile communication service. This study suggests 6 components of service quality: those are supporting facilities, cellular phone(facilitating goods), quality of the voice service(explicit service), supplementary services, supporting services, and cost. Empirical results supported that all of these components are proven as the service quality components, but, with regards to customer satisfaction, only cellular phone(facilitating goods) and supplementary services are effective. As previously stated, the relationship between service quality and customer satisfaction is also proven. This study is a point of departure for the success of upcoming generation's mobile communication service. It identifies what is valuable from the customer's point of view. Furthermore, it suggests some ideas to prepare for future market opportunities.

The lifestyle of customers visiting nail shops is categorized into four such as the types of 'pursuit of fashion', 'pursuit of brand', 'conservative frugality', 'premeditated pursuit'. Subjects are divided into 3 groups such as a 'pragmatist group', an 'achievement-oriented group' and a 'brand-oriented group'. Customers satisfaction level was measured in the subcategories of a 'personal service', a 'technical service', a 'facility service' and an 'after-sales service'. Their satisfaction levels depending on the types of customers' lifestyle have meaningful differences in a 'technical' and an 'after-sales' service. The 'pragmatist group' shows the highest mark in a 'personal service' and an 'achievement-oriented', it prefers the 'personal' and 'facility service' evenly. The 'brand-oriented' group shows high concern in the 'technical service'. Concludingly, the types of customers' lifestyle which influence their revisiting of the nail shop have deep relation to customers' satisfaction level in the 'personal', 'technical', 'facility', and 'after-sales service' of nail shops. Especially the 'facility service' is highly influential in customer's revisiting.

본 논문에서는 인터넷 QoS(Quality of Service)보장을 위하여 제안된 Diff-Serv(Differentiated Service)모델을 구현하고, QoS 를 보장하지 않는 BE(Best Effort)서비스와 우선 순위가 높은 패킷을 처리하여 QoS 를 보장하는 EF(Expedited Forwarding) 서비스의 차이를 통하여 Diff-Serv 망의 우수성을 입증하고자 한다. Diff-Serv 망은 BB(Bandwidth Broker)와 에지라우터 그리고 다수의 코어라우터로 구성된다. BB 로부터 라우터에 QoS Policy를 전송하기 위하여 COPS(Common Open Policy Service) 프로토콜을 구현하였으며, 사용자와 BB 사이의 SLAT/RAR(Service Level Agreement/Resource Allocation Request)를 처리하기 위하여 Admission Control 이라는 명명한 자체 프로토콜을 개발하였다. 구현된 Diff-Serv 망에서 QoS 보장 테스트를 위하여 19.2Mbps 대역폭이 요구되는 HDTV 스트리밍 서비스를 이용하여 인위적으로 Background Traffic 을 발생시켰을 때, BE 서비스만을 지원하는 망에서는 현저하게 서비스의 질이 떨어지는 반면에 Diff-Serv 망에서는 QoS가 보장됨을 알 수 있었다.

To analyze the roles by abilities between manpower through the analysis of industrial health service agency personnel, 115 industrial health service agency personnel in 19 Industrial Health Service Agency personnel scattered in Seoul and Kyungki areas have been investigated according to the questionnaires formulated in line with the Likert 5-point scale from September 1 through October 30, 1995 and the following significant result has been obtained: 1. The job abilities by fields. 1) In the field of health care, the level of medical personnel's job ability was 3.30 on average and that of industrial hygienists' was 2.54 on average, which showed that the level of medical personnel's job ability was higher. 2) In the field of health management, there was a difference between the level of medical personnel's job ability and that of industrial hygienists' only in the health education but there was not so much difference between manpower' which showed that it was 3.00 on average. 3) In the field of working environment management. the level of industrial hygienists' job ability was 4.03 on average and that of medical personnel's was 2.62, which showed that the level of industrial hygienists' job ability was higher than that of medical personnel's. 2. The job abilities by manpower. As for the job ability by manpower. on the health care the medical personnel's ability was more excellent than the industrial hygienists' and on the working environment management the latter's{industrial hygienists') ability was more excellent than the former's(the medical personnel's). However. the field that a difference between both manpower as mentioned above was not recognized was the health management. 3. As for the difference of potential factors between manpower. in Factor '1' the industrial hygienists' 80.7 points by percentage was higher than the medical personnel's 52.5 points and in Factor '2' the latter's(medical personnels's) 72.6 points by percentage was higher than the former's{industrial hygienists') 50.6 points in the level of job abilities. The above result shows that the industrial health service agency personnel can be classified into the job with a difference between manpower and that without any difference manpower. Therefore, the following issues: First: The field of health care shall be defined as the medical personnel's exclusive job. Second: The field of working environment management shall be defined as the industrial hygienists' exclusive job. Third: The field of health management shall be defined as a common job to lead the limits of time and space in the collective group occupational health management to be controlled effectively.
