본 연구의 목적은 신규 금융보안서비스(OTP, HSM)의 채택에 있어 개인사용자에게 영향을 미치는 요인을 도출하고자 함에 있다. 연구방법으로는 기술수용모형(TAM)을 기반으로 새롭게 보안에 관한 변수를 추가하여 확장된 기술수용모형을 사용하였다. 현재 등급별 이체한도에 따라 기업의 거래이용수단에 적용되는 제약은 향후 개인사용자에게의 확대될 예정이다. 따라서 본 연구는 개인사용자를 대상으로 하여 실증적인 연구를 실시하였다. 분석 결과, 신규 금융보안서비스의 채택에 있어서 개인사용자는 인지된 편의성과 보안성을 직접적으로 수용의도에 반영하지는 않지만 인지된 유용성을 통해 간접적으로 반영하고 있으며 직접적으로 수용의도에 영향을 미치는 요인으로는 인지된 유용성만이 유일한 것을 밝혀내었다. 따라서 본 논문은 금융보안서비스가 개인에게 확장될 경우 가장 중요한 요인이 인지된 유용성이라는 사실과 인지된 유용성은 보안성보다는 사용자의 용이성에 더 많은 영향을 받음을 확인함으로써 향후 실사용자가 될 대상에게 더 유용하고 용이한 금융보안서비스를 제공해야 함을 시사하는 바이다.

확장성과 유용성 그리고 간편성과 가격 효율성 측면에서 발전을 거듭하고 있는 이더넷은 가장 광범위한 커버리지를 확장해 가고 있으며 최근 전력시스템에도 그 적용성을 넓히고 있다. 또한 이미 표준화가 이루어진 기술과 많은 사용자로 인한 기술적 이해도가 높고 쉽게 구현할 수 있다는 점에서 최근 스마트그리드의 표준 인터페이스와 네트워크 표준으로 활발한 연구가 진행 중이다. 그러나 모든 통신망이 그러하겠지만 특히 이더넷 통신망의 경우 안정적인 동작과 중단 없는 서비스를 통하여 통신망의 효율성을 극대화하기 위해서는 통신망의 고장이나 성능의 저하에 대응하기 위한 관리방안이 필요하다고 하겠다. 따라서 논문에서는 이더넷 기반 링형 네트워크에서의 보호절체 메커니즘과 배전자동화 시스템에 대한 적용을 위한 다양한 적용기술에 대해 기술하고자 한다.

According to the changes of current regulation of media, the broadcasting environment has been loosened by market power, and came into competitive era for broadcasting industry with new technology of combined broadcasting and communication. To resolve these issues, the broadcasting provides are trying process of new channel brand identity to introduce their channels. The purpose of the research is to analyze Spot animation that has fast access to viewers among channel brand identity factors, review expandability and usage of Spot animation character to plan, manage character that can improve awareness and loyalty. Therefore it will study creation background and production, activities of each character representing KBS and MBC, compare the structure, color, material, expression of Spot animation character and summarize properties. To conclusion, three characters of KBS and MBC failed to apply structured and professional plan and management, only expressed image that each channel pursue on Station ID Spot animation and had issues of not deeply sighting expandability and usefulness as a character. The important factor to improve channel brand value of broadcasting provider is to have differentiated identity, and the core of it is to make image-responsible Station ID to be effective. Therefore, Spot animation and character of Station ID is a very important factor so there must be professional research and structural management from the early planning and production for character that represents the providers.

The purpose of this study is to identify belief variables of kiosk that affect satisfaction and recommendation intention by applying vertically extended technology acceptance model (TAM). As results of this study are as follows. Firstly, the perceived usefulness and perceived ease of use have an impact on satisfaction statistically. Second, the perceived usefulness and perceived enjoyment of the kiosk showed a positive(+) influence on the recommendation intention. Third, users who satisfied with kiosk service have strong recommendation intention to their friends, family and colleagues so on. These findings support that the usefulness and usability of the new information technology identified in the existing technology acceptance model is a key variable affecting user reactions (satisfaction and recommendation intention). Additionally, the perceived enjoyment is an important factor as new belief variable for explaining the formation of recommendation intention through satisfaction of kiosk service. The results of this study contribute to verifying the empirical model between the belief variables(perceived usefulness, perceived ease of use, perceived enjoyment) and the recommendation intention.

The purpose of this study is to investigate the influence of exogenous variables on the intention to use AI speaker. An online survey was administrated to 305 AI speaker users in order to examine the effect of the personal characteristics (self-efficacy, innovativeness, suitability, and enjoyment) and social impact (social conformity and social image) on perceived usefulness and easiness. The results indicate that (1) self-efficacy and social conformity have positively effect on perceived easiness; (2) suitability and social image have positively effect on perceived usefulness whereas innovativeness has negatively effect on perceived usefulness; (3) perceived usefulness and perceived easiness have significant effect on the intention to use AI speaker.

The purpose of this paper is to examine factors influencing e-Learning acceptance intention through extended Technology Acceptance Model(TAM) applying TAM, the motivation theory, and the social response theory. To do this, this paper proposes and analyzes a theoretical model consisting of factors such as perceived sociability, perceived ease of use, perceived usefulness, perceived enjoyment, and e-Learning acceptance intention. Our findings are revealed as following: First, perceived usefulness and perceived enjoyment have positive effects on e-Learning acceptance intention. Second, perceived ease of use has positive effects on determinants of e-Learning acceptance intention. Third, perceived sociability not only has direct influence on e-Learning acceptance intention but also has indirect influence carried by perceived usefulness.

This study empirically analyzed factors affecting consumers' intention to use metaverse by applying the extended technology acceptance model. In other words, the factors affecting the intention to use the metaverse were set as content quality, perceived enjoyment, social influence, self-efficacy, and investigated from the perspective of the expanded technology acceptance model. For this end, a survey was conducted on 296 university students in Seoul, and the collected data from 267 students were analyzed using SPSS 25.0 and AMOS 23.0. As a result, it was found that perceived usefulness and perceived ease of use, which are the antecedent variables of the extended technology acceptance model, affect the intention to use the metaverse, and perceived ease of use has an effect on perceived usefulness. Content quality and perceived enjoyment had an effect on perceived usefulness, perceived ease of use and intention to use metaverse. Social influence was found to affect perceived usefulness and intention to use metaverse. Also, self-efficacy was found to affect perceived ease of use and intention to use metaverse.

This study investigated the structural relationships among factors on intention to use mobile learning and suggests practical strategies to enhance learners' behavior intention in secondary school. In this study, we hypothesized that mobile computing self-efficacy, personal innovativeness, and social influence had positive effects on perceived usefulness and perceived ease of use, which ultimately had positive effects on intention to use mobile learning. In order to examine structural relationship among variables, we surveyed 289 high school students in spring semester of 2014. After collecting data, we examined causal relationship among variables using Structural Equation Modeling. The results of this study are as follows: First, mobile computing self-efficacy and personal innovativeness significantly affected perceived ease of use. Second, mobile computing self-efficacy, social influence, and perceived ease of use significantly affected perceived usefulness. Lastly, perceived usefulness and perceived ease of use significantly affected intention to use mobile learning of high school students.

This study investigated the antecedents of VR(virtual reality) headsets acceptance and the causal relationships among self-efficacy, content diversity, the perceived usefulness, the perceived easy of use, the perceived playfulness and the adoption intention. We collected 238 survey responses and formed structural equation modeling with AMOS 23.0. The results of the analysis can be summarized as follows. The diversity of contents and self-efficacy had significant effects on perceived usefulness, perceived ease of use and perceived enjoyment, thus increasing the intention of acceptance. Perceived usefulness, perceived ease of use and perceived enjoyment had significant effects on the intention of acceptance. Perceived ease of use indirectly had an effect through increasing perceived enjoyment. The price did not affect the adoption intention and marketing communication increased the intention of acceptance. The results are expected to provide useful information to the companies related to VR.
