To protect information resources, many organizations including private corporate and government employ integrated information security systems which provide the functions of intrusion detection, firewall, and virus vaccine. So, in order to develop a reliable integrated information security system during the development life cycle, the managers in charge of the development of the system must effectively distribute the development resources to the quality factors of an integrated information security system. This study suggests a distribution methodology that minimizes the total cost with satisfying the minimum quality level of an integrated information security system by appropriately assigning development resources to quality factors considered. To achieve this goal, we identify quality factors of an integrated information system and then measure the relative weights among the quality factors using analytic hierarchy process (AHP). The suggested distribution methodology makes it possible to search an optimal solution which minimizes the total cost with satisfying the required quality levels of processes by assigning development resources to quality factors during the development life cycle.

This paper classifies the success factors of collaboration system in the shipbuilding industry. We propose the structural model that identifies the relationship between the success factors and organizational performance. To test empirically the relationship between the factors, we developed the measurement of each factors. This paper has examined the relationship between the independent variables and the mediating variables, also has examined the relationship between the parameters and a final dependent variable. The independent variables are as follows, (1) quality of system including reliability, flexibility, and accessibility, (2) the quality of information including contents, expressiveness, and (3) the partner relationship including the information sharing and the compatibility of strategies. The mediating variables are user involvement, parter trust, and user satisfaction. The final dependent variable is business performance. The hypotheses test proved that the system quality significantly affect user satisfaction, the information quality positively influence on the user participation, and the information sharing and strategic fit of partner relationship positively affect partner trust. Also, the user participation and partner trust significantly affect user satisfaction. Finally, the user participation, user satisfaction, and partner trust have a decisive effect on the organizational performance. The results of hypothesis test verified that the quality of information and system, also partner relationship are important to operate successfully the collaboration system in the shipbuilding industry. Also, the mediating variables are important to explain the structural relationship between the independent variables and organizational performance.

본 연구의 목적은 ERP시스템의 품질요인이 조직성과에 어떠한 영향을 미치는가를 실증적으로 조사 및 분석하였다. 많은 선행연구들이 일반품질요인에 초점을 두는 대신에 본 연구는 설문지를 사용하여 ERP시스템을 채택한 기업에 있어서 품질요인과 조직성과간의 상호관련성을 조사 연구하였다. 특히 선행연구들은 시스템품질과 정보품질만을 연구대상으로 설정한 것이 주류를 이루고 있는데 본 연구에서는 서비스품질을 추가하여 조직성과와의 관련성을 연구하였다는데 의미가 있다. 설문지는 ERP시스템을 도입한 기업을 대상으로 품질요인과 조직성과간의 관련성의 설문으로 구성된다. 연구결과는 다음과 같다. 첫째, ERP시스템의 품질요인이 조직성과에 t검정으로 영향을 미친다는 것이다. 둘째, ERP시스템의 품질요인이 t검정으로 조직성과에 통계적으로 유의하게 영향을 미친다는 것이다. 이 결과는 실무계 및 교육계에 유용한 통찰력과 정보를 제공할 것으로 기대한다. 첫째, ERP시스템을 기업이 도입할 때, 품질요인이 조직성과에 유의적인 영향을 미친다는 것을 사전에 숙지하고 품질요인에 대한 투자와 연구가 행되어야 한다는 것이다. 둘째, 본 연구는 지금까지의 선행연구와는 달리 서비스품질을 추가하여 연구함으로써 품질요인을 세부적으로 접근하였다는데 그 실용가치가 높다고 판단되며, 셋째, 본 연구는 ERP시스템의 품질요인의 질적향상에 대한 학문적 기초를 제공한다.

Mobile payment system using NFC attracted attention as the mobile payment market grows due to the fast diffusion of smart phones. However, non NFC mobile payment recently appeared because of the slow growth of infrastructure for NFC. With advent of Non NFC mobile payment applications, mobile payment industry is in developing trend. Non NFC mobile payment revitalizes the market by overcoming the limit of NFC with the smart applications using bar code and QR code payment, and providing various discounts, membership benefits and payment information. Therefore, this paper analyzed the intention of continuous use with the quality of mobile payment application based on the information system success model. Three categories of factors which are system quality, service quality, and information quality were used. We verified the significance of the factors affecting the intension of continuous use. mainly, quality of information was considered as an important factor of continuous Intention to Use. Also, unlike previous NFC, it was found that in Non-NFC, compatibility might not be as important factor. Moreover, we suggest a marketing strategy of companies for mobile payment industry which focus on information quality. and future research directions for non NFC payment market.

Recently, interest in ChatGPT has been increasing. This study investigated the factors influencing the satisfaction of users using ChatGPT service, a chatbot system based on artificial intelligence technology. This paper empirically analyzed causality between the four major factors of service quality, system quality, information quality, and security as independent variables and user satisfaction of ChatGPT as dependent variable. In addition, the mediating effect of reliability between the independent variables and user's satisfaction was analyzed. As a result of this research, except for information quality, among the quality factors, security and reliability had a positive causality with use satisfaction. Reliability played a mediating role between quality factors, security, and user satisfaction. However, among quality factors, the mediating effect of reliability between service quality and user's satisfaction was not significant. In conclusion, in order to increase user satisfaction with new technology-based services, it is important to create trust among users. The research results sought to emphasize the importance of user trust in establishing development and operation strategies for artificial intelligence systems, including ChatGPT.

This study addresses the development of a quality measurement of information systems integration(SI) service. Several dimensions which affect on quality of systems integration service have been identified and tested. Also, a measurement tool(questionnaire) of the factors has been developed. To achieve above purpose, extensive literature review and in-depth interview with several SI managers and customers were used. We suggested the analysis framework including performance variables such as quality, customer satisfaction, intention of renewal contract, and contribution to better customer's information system and the quality factors as well. To verify the research framework, collected data from the survey was analyzed statistically. The data from 73 respondents was used for analysis. Consequently, we identified eight factors and developed a 41-item instrument with Likert 5 points to measure the quality of SI service. It was proved that the 41-item instrument suggested in this study was very useful to measure the performance of SI service such as quality and customer satisfaction. Also it was shown that the instrument measured intention of renewal contract and contribution of customer's information system well.

Parasuraman, Zaithmal, 그리고 Berry에 의하여 개념화된 서비스의 결정 요인인 신뢰성, 반응성, 보장성, 공감성, 유형성의 차원이 WIS환경에서 적합한지 분석한 결과 측정척도로서 SERVQUAL을 사용할 경우 반응성과 보장성, 공감성과 유형성, 신뢰성의 3개 요인으로 사용되어 질 수 있으며, SERVPERF를 사용할 경우 5개 요인이 사용되어질 수 있었다. 품질결정요인 중 신뢰성과 유형성이 유의하게 서비스 품질에 영향을 미치는 것으로 나타났다. 컴퓨터 사용환경이 더욱 분산된 형태를 띠는 WIS환경에서는 사용자 지원서비스를 위하여 공식적 정보센터뿐만 아니라 비공식적 정보센터를 효율적으로 활용해야 할 것이다.
