This study developed digital literacy instruments and tested their effectiveness on college students' perceptions of AI technologies. In creating a new digital literacy test tool, we reviewed the concept and scale of digital literacy based on previous studies that identified the characteristics and measurement of AI literacy. We developed 23 preliminary questions for our research instrument and used a quantitative approach to survey 318 undergraduates. After conducting exploratory and confirmatory factor analysis, we found that digital literacy in the age of AI had four ability sub-factors: critical understanding, artificial intelligence social impact recognition, artificial intelligence technology utilization, and ethical behavior. Then we tested the sub-factors' predictive powers on the perception of AI's usefulness and ease of use. The regression result shows that the most common powerful predictor of the usefulness and ease of use of AI technology was the ability to use AI technology. This finding implies that for college students, the ability to use various tools based on AI technology is an essential competency in the AI era.

The era of "ownership" has gone, and the era of "subscription" has come. While traditional manufacturing and service industries are struggling with the fall of earnings rates, subscription-based businesses are showing high growth rates. Although subscription-based online services (SOS) are rapidly growing in the retail market, few studies have investigated factors that affect the decision of consumers to use SOS. Therefore, this study aims to identify factors that enable predicting consumers'attitudes and intentions toward SOS and to empirically verify the factors. As a result of the study, usefulness, enjoyment, and cost advantages were shown to have positive effectson perceived value, and usefulness, technicality, and cost advantages were shown to have positive effects on attitudes. In addition, perceived value was shown to have positive effects on attitude, and perceived value and attitudes were shown to have positive effects on acceptance intentions. The fact that the strategic directivity for successful introduction and diffusion of SOS was presented by identifying the predictor variables for the acceptance of SOS through this study can be said to be the significance of this study.

본 연구는 인터넷 뱅킹 서비스가 성숙기에 접어 들면서 고객들의 인터넷 뱅킹이라는 기술을 수용하게 되는 과정과 이유 파악이 필요하며, 고객의 입장에서는 인터넷 뱅킹 서비스가 어떤 단계를 거쳐 어떻게 이용되는지 알아보고 인터넷 뱅킹의 지속적 고객수용에 영향을 미치는 외부적 요인을 실증적으로 분석하였다. 외부적 요인으로는 사용자지식, 서비스 특성, 보안, 인지된 위험, 사용편리성 그리고 유용성을 사용하였다. 실증분석을 위한 틀로서 TAM을 기초로 변형한 Ex-TAM을 재구성하여 분석하였다. 결과로서 4개의 요인 (서비스 특성, 사용편리성, 유용성, 신뢰)이 유의하게 나타났다. 반면, 2개의 요인(보안, 인지된 위험)은 유의하지 않았으며 1개의 요인(사용자 지식)은 부분적으로 유의하게 나타났다.
