As having analyzed an advance research that had looked into how characteristics of information system affect use and success of the concerned system, the study determined that system quality, information quality and service quality are the fundamental requirements for a good accounting information system. In addition, based on perceived usefulness and perceived ease of use that have been selected as major variables related to information system acceptance proposed by Davis[10], the study conducted an empirical analysis on how such factors would influence performance of the accounting information system. According to the results from the analysis, the system quality one of the characteristics of the accounting information system was observed to have a significant influence on the perceived ease of use while both the information quality and the service quality would positively affect the perceived usefulness. Not only that, the perceived ease of use and the perceived usefulness were confirmed to be a significant factor to the performance, and with those results, all the theses of the study have been selected. As proved even with the information system success model, the system quality, the information quality and the service quality are definitely the most necessary elements for business management, and it also turned out that those elements would play an important role in several stages of the information system.

Purpose With the continuous growth of the OTT services market, trust issues are becoming increasingly important, but research on this topic is still in its infancy. The purpose of this study is to identify the structural relationship between information system quality and reuse intention of OTT services and to analyze the impact of trust and user satisfaction. Design/methodology/approach This study proposed a research model based on the information system success model. In this study, a survey was conducted among 236 Korean users who have used OTT services within the last six months. Findings The results of the analysis showed that text quality and visual quality had a significant impact on trust in OTT services, with text quality having the largest impact. System quality and text quality also had a significant impact on trust in OTT service providers. However, visual quality did not have a statistically significant effect on trust in the service provider. Trust in the OTT service and the service provider was analyzed to have a significant impact on user satisfaction. However, it did not have a statistically significant impact on reuse intention. These findings have important implications for improving trust in OTT services to increase users' reuse intentions. It is also expected to contribute to further expanding the field of OTT service research.

This study examines the factors influencing internet protocol television (IPTV) usage intention. Using Davis's technology acceptance model (TAM) and DeLone and McLean's model of information system success, this study investigates the effects of information system quality (information quality, system quality, and service quality) and media quality on IPTV use in terms of perceived usefulness, perceived ease of use, and usage intention. We examined the proposed model by employing structural equation modeling and survey data from 222 IPTV users. The results indicate that information quality, service quality, and media quality had significant effects on perceived usefulness and that information quality and media quality had significant effects on perceived ease of use. However, system quality had no effect on perceived usefulness or perceived ease of use. In addition, perceived ease of use influenced perceived usefulness, and perceived usefulness and perceived ease of use influenced IPTV usage intention. Further, the stability and reliability of IPTV services encouraged IPTV use, and successful IPTV services showed high media quality.

Full motion video data is the most effective data type that transmits information in multimedia enviornment. VOD service is system that uses network to transmit full motion video data interactively. Therefore VOD service system must satisfy the following requirements. First, it should transmit high quality full motion video. Second, it should be able to control a large quantity of full motion video. Third, a user should be able to retrieve the full motion vide effectively. However the existing VOD service system is established based n file system that not only does it have disadvantages in managment such as transaction control but also it is not suitable for distributed multimedia environment. The goal of this research is to build a VOD service system that provides high-quality full motion video assuming information retrieval. In order to mainly search video data's bibliographical information and to manage related information, VOD service system and DBMS system are to be closely related. Also, to transmit high quality full motion video data, we use MTP$^{TM}$(Media Transfer Protocol) developed by StarLight. MTP$^{TM}$ guarantees high bandwidth that is necessary to tansmit high quality full motion video data effectively. In other hand TCP/IP which is used for information search does not guarentee high bandwidth as that in MTP$^{TM}$. Therfore VOD service system that seraches information managed by DBMS and transmits requried full motion video data should control different kinds of protocol simultaneously. This paper describes the configuration of VODB system that has solved these problems, implementation and efficiency of data applied system.stem.

The qualities of the technological artifact of online shopping websites and the overall support delivered by the service provider through the website are generally agreed to be crucial elements in creating customer satisfaction and loyalty. However, a lack of consensus exists on how those qualities are related to each other, what they consist of, and how they can be conceptualized. Based on relevant literature and using a servicescape framework as a theoretical lens, we divide online shopping website qualities into information and system qualities and argue that both factors affect service quality. We conceptualize each of the three types of quality as a second-order formative construct comprising its most salient quality dimensions: information quality consisting of reliability, understandability, currency, and relevance; system quality consisting of usability, availability, and responsiveness; and service quality consisting of efficiency and fulfillment. Our model of how information, system, and service qualities are related to one another and to customer satisfaction and loyalty is then tested empirically with a data set of 570 online shopping customers. Our integrated model reconciles the seemingly contradictory conceptualizations of previous researchers and provides an effective way to create customer satisfaction and loyalty.

As Information Technology has developed, The structure of information system used in organizations is changing from centralized computing structure to distributed computing structure. The roles of information department have expanded, which is not only develope and maintain system but also provide usage-support service to end-user. If organization support end-user properly, they get many benefits. if they don't do it properly, they waste many resource. Therefore, the purpose of this study is the search for quality determinant factors and type of information that provide user effective service under web-based information system. The result of this study is as follow First, when SERVQUAL is used, the quality determinant factors of usage-support service are categorized three, which is responsibility and assurance, empathy and tangable, and reliability. When SERVPERF is used, the determinant factors consist of five, but the use of assurance as a factor is cautious. Second, reliability and tangability among determinant factors affect general service quality, and tangibility is most important factors. third, When the locations of user are distributed the degree of general service quality is not different whether formal or informal information center provide usage-support service. This study may suggest practical implication as follows; First, as user are good at to use information system the degree of importance for tangibility are decreased. when user are individualized and improve their ability to use information system, empathy will not be important factors any more, therfore it assume that reliability will be most important factors. Second, if organizations promote not only formal informaton center but also informal inforamtion center they may support end-user more effectively. However, this study has the following limitations: First, it is difficult to generalize the result of this study Second, service quality determinant factors used in this study don't explain the influence to general service quality fully. Third, this study analyze a simple relation between service quality determinant factor and general service quality. Finally, this study don't distinguish between information system service and information support service.

In the information system service sectors, it is crucial to measure the quality of service. Especially factors determining the quality of service should be identified. For that purpose, in this study, the factors of two research models-SERVQUAL and TAM-are compared, analyzed and tested with data of public procurement system service. The result shows that the factors identified include reliability and assurance of SERVQUAL and perceived usefulness and perceived ease-of-use of TAM. Also, it is observed that the two models sufficiently explain the variance of satisfaction. This study may help improve the quality of information system service.

The information service management models developed thus far have put their focuses mostly on technical dimensions of information systems (IS), finding their rationale from the goods-dominant logic (GDL) that IS as goods has value in itself. Information systems, however, is nothing more than a mechanism by which value is delivered to the users. According to the service-dominant logic (SDL), value is created and determined not at the time serve is made by the providers but at the time it is consumed by the users. The users therefore should be regarded as active value creators not as passive consumers of the value delivered by the providers. Based on the service-dominant logic, DISQM (Dynamic Information Service Quality Model) is developed. DISQM's backbone is designed in causal loop diagrams referring to and reinterpreting in systems thinking the 'Parasuraman, Zeithaml & Berry's GAP Model' and 'SERVQUAL' as an operational tool for the GAP Model, and the main IS success constructs are mapped onto the model exploiting the 'DeLone & MacLean's IS Success Model'. With VENSIM simulation software, this paper also shows how DISQM works in computer-simulation settings. After confirming DISQM's validity with the base simulation run, two scenarios are developed for the exemplary purpose and tested in terms of IS quality, service quality, and net benefits from the service for the public information service. Implications from the simulation runs are also discussed.
