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.

The purpose of this study is to develop a Technology Acceptance Model (TAM), to determine differences in gender perceptions in adopting non-cash transactions. In this study, the authors provide a measurement of differences in gender perceptions in adopting cashless, which refers to perceived usefulness, perceived ease-of-use, and perceived security. Respondents in this study were students from the millennial generation who are very familiar with the use of technology, especially non-cash transactions. The data collection technique used in this study was a survey, by distributing questionnaires to 260 respondents. The data were processed statistically through Structural Equation Modeling (SEM). The results of this study indicate that for men, ease-of-use of transactions does not increase the use of non-cash transactions. Meanwhile, for women, perceived ease-of-use has a significant and positive effect on the use of non-cash transactions. Furthermore, perceptions of usability and security have a positive and significant impact on using non-cash transactions. It was also found that female students had a positive, but not significant, effect on the use of non-cash transactions. This means that there has been a difference in the perception of gender, between men and women, in responding to the use of non-cash transactions.

본 연구의 목적은 정보기술 수용분야의 중요한 연구 이론이었던 기술수용모델을 바탕으로 시스템 요인과 협력 요인을 적용하여 VMI 사용 의도를 실증적으로 검증하고자 하였다. 분석한 결과 시스템 요인은 VMI 사용에 대한 유용성과 용이성에 긍정적 영향을 미쳤으며, 사용에 대한 용이성은 다시 유용성에 긍정적인 영향을 미쳤고, 용이성이 사용의도에 영향을 미치는 것을 검증되었다. 한편, 본 연구에서의 유용성은 사용의도에 유의한 영향을 미치는 변수가 아닌 것으로 나타났다. 이는 선행연구에서 나타난 것처럼 사용자가 VMI의 유용성에 대한 이해도가 다소 부족한 것에 기인한다. 그러나 VMI가 공급사슬관리에서 정보시스템으로 자리 잡은 현 시점에서 판단한다면 기술수용모델은 VMI 사용의도를 설명하는 이론적 토대가 됨을 확인했다.
