The purpose of this study is to analyze service quality factors that affect user satisfaction of NDSL Open Service (NOS) and to improve standards of open service for sharing information through the user satisfaction survey. User satisfaction indexes were developed to measure the all aspects of the NOS services. The quality index, satisfaction index, and performance index were identified in this survey. According to the survey findings, the levels of social quality and social satisfaction are relatively high, this shows the positive evaluation and expectation of researchers for open services. However, relatively low level is identified in area of service process quality. Therefore, NOS requires method to help easily take advantage of OpenAPI and strategy to increase service process satisfaction and service environment satisfaction.

최근 IT인프라 관제시스템의 구축 추세는 서비스 가용성 및 응답시간이란 관리지표를 기준으로 IT서비스 품질관리 관점에서 시스템을 관리함을 목표로 삼고 있다. 즉, 자원의 종류에 따라 개별 성능 및 장애 관리를 하기보다는 서버, 네트워크, DB, WAS, 어플리케이션 등 IT서비스에 관련된 전반적 자원에 대한 포괄적인 관리로 IT서비스 성능저하 및 장애가 주로 발생하는 지점을 파악하여 보수하고 개선할 수 있는 시스템을 구축하는 것이 최근의 추세라 할 수 있겠다. 한편으론 조직의 IT서비스가 여러 지역에 존재하는 다수 시스템에 의해 수행되는 최근의 상황을 고려할 때, 분산 환경하의 서비스 품질관리를 위해서는 각 지역별로 관리 서버를 운용하고 중앙에 별도의 슈퍼 매니저를 두어 전체를 관장하는 체계가 요구된다. 다중/계층형 관리서버 운용 메커니즘을 지원하는 시스템에서의 각 관리 모듈은 독립적으로 실행이 가능하며, 물리적 서버의 위치가 다른 곳에서도 관리 기능을 실행함에 있어서 문제가 없도록 기능을 지원하여 관리서버의 부하 분산이 투명하게 실현되어야 한다. 여기서는 QoS (Quality of Service)측면에서의 관리 기능을 수행하는 다중/계층형 시스템 통합관리에 관한 기술적 사항들을 살펴보고자 한다.

As rapid development of the Internet, there are increasing interests about quality of service of VoIP using the Internet network and established PSTN. There was some study going on to improve the quality of service from the point of view of supplier's mainly. However recently, the demand for setting up the objective standards that service provider can offer to customers is needed as the interests from customers has been going up. In this study, we analysed the results from the test using PESQ which is a parameter of quality of service. we offer the conditions of network which guarantees the minimum quality of phone call using VoIP.

This paper addresses quality of experience(QoE) and how to measure and evaluate QoE including its subjective aspects. Adopting the real measurements on the field, a various quality metric have been measured for VoIP(voice over IP) service provided through a wireless interface of WiBro(Wireless Broadband). By analyzing the measured values and correlation between the metrics, we attempt to find a method to evaluate QoE of the VoIP service in a objective way. As a result, it has been shown that QoE of the VoIP service through WiBro network has close relation to the packet-level end-to-end delay, and the delay has close relation to received signal strength indicator(RSSI).

In the past, customers utilize a secondhand book market as a major counter for their purchasing used books. With expansion of internet and IT devices, many customers would like to buy their used books in an on-line secondhand book store which has more price competitiveness and ease. Nowadays a new concept off-line secondhand book market which has the advantages of both on-line and off-line is a growing trend instead of existing secondhand book markets in the economic recession. In this study, we established customer service satisfaction for 'Aladin store', which is the advanced concept off-line secondhand book store, with the most typical service quality test technique SERVQUAL. First, we selected appropriate service quality factor for the advanced concept off-line secondhand book market such as Aladin store. After that, we analyzed which factors are influencing repurchase intentions, through customer survey. The conclusion provides the secondhand book store's service quality improvement and strategy toward customer satisfaction including the existing used book stores.

The purpose of this study is to compare the national quality regulation schemes among four countries, and to find out implications to Korean quality regulation system of social services. For this, this study fixed comparative criteria on national quality regulation schemes, and compared the quality regulation schemes of 4 countries such as England, United States, Singapore and Japan. By reviewing prior relevant studies, three criteria could be suggested.: the level of user centeredness, the effectiveness of regulatory enforcement and stability of operation system. All analysed nations share similarities in that they all eager to provide quality information to their service users and develop nationally acceptable quality standards of social services. On the contrary, differences are identified in the level of regulatory enforcement and establishment of independent body for national quality control. By these results, this study discussed the meaning of these findings and their implications on the development of Korean quality regulation system.

The purpose of this study is to measure the expectation level and perception level of service quality in 25 records centers in local governments based in Seoul. For this, an evaluation index consisting of 5 factors and 31 items is developed through literature research and an investigation of the present condition. The results of this study confirmed that users are not satisfied with the service quality of the records centers in the local governments as the expectation level is higher than the perception level, with a statistically significant difference. This study can be substantial in attempts to analyze the present status of the service quality of the records centers in local governments and in proposing an improvement plan based on the process quality.

According to increasing activities in the cyberspace, various on-line services through the Internet have been offered, and many recent studies on the Internet services such as instant messenger, game, and portal site have been performed to evaluate quality of these services. However researches on weblog(blog), a personal online journal for general public consumption, have not been performed much yet. Therefore, we have conducted an empirical study on investigating the structural relationships among weblog service quality, satisfaction and loyalty in this study. After reviewing the related literatures, we have suggested a model for evaluating the service quality of weblog, wb-SERVQUAL(weblog-SERVQUAL), by modifying the conventional SERVQUAL model based on characteristics of weblog. Structural Equation Model(SEM) has been used to analyze the structural relationships among service quality of weblog, user satisfaction and customer loyalty. Managerial implications are also suggested for managing the weblog sites in conclusion.

The Port Logistics Information System (Port-MIS) is the system that processes all of port management such as entry and departure of ships, using facilities within ports, port traffic control, cargo entering and carrying and tax collection in 31 trade ports over the whole country. Lately, The Port Logistics Information System (Port-MIS) has been reformed as a WEB-based system and established basis to provide real time information support structure, diversification of civil complaint system, and optimized civil complaint service by using wire and wireless internet. The typical study on the Port Logistics Information System was C/S program and EDI-centered. But it has significance to study on service quality measurement of WEB Port-MIS that has been served as a new web-based platform since April 2010, for there was no such a study until now.
