An intelligent personal assistant (IPA) is a software agent that assists people to perform basic tasks or services for an individual by commonly providing information via natural language. In spite of the versatile capabilities of the IPA to answer a user's simple information-based queries, such as the weather and driving directions, the actual usage rates for IPA services are limited to date. In this research, to evaluate the factors affecting the intention to use IPA, we develop an empirical model based on technology acceptance model, innovation diffusion theory, and IS success model. Afterward, we collect 203 questionnaires from actual users of IPAs. Finally, the structural equation model validates the causal relationship between the constructs of the model. Consequently, the innovation characteristics of IPA drawn from innovation diffusion theory, namely, relative advantage, compatibility, observability, all exerted a positive influence on perceived usefulness. Furthermore, information quality, a quality characteristic of IPA obtained from DeLone and McLean's IS success model, presented a positive effect on perceived usefulness and perceived ease of use. Finally, the perceived intelligence of IPA displayed a positive influence on perceived usefulness and ease of use. This characteristic was also a major factor that can increase the intention to use the IPA. Given these research findings, this study is significant for identifying factors that may influence the intention to use the IPA by providing strategic guidelines to relevant business operators and establishing an integrated model.

Internet only Banks in Korea have acquired more than seven million customer base, but most of the accounts are not active. As financial products tend to be similar, customer affect plays more crucial role than service features in continuance intention. The purpose of this research is to study about the impact of positive and negative affect on the continuance intention. The result indicated that positive affect is positively related to continuance intention, and negative affect is negatively related to continuance intention. Also expectation confirmation is positively related to positive affect. The results imply Internet only Banks need to focus on customer's positive affect and expectation confirmation to improve continuance intention.

현대의 소비자는 더 이상 단순히 감성적 소구에 의해서나 기술적 기능을 제공하는 것으로 제품을 구매하지 않는다. 제품의 결정은 사용자와 제품 간의 상호작용에 따른 정서, 인지, 행위 등에 의한 총체적인 경험에 의한 것이며, 그러한 소비자들의 경험은 지리적, 역사적 전통으로 고착된 문화적 특성이 제품을 통한 사용자 경험의 기저에서 작용함으로써 문화권 별, 국가 별로 각기 다르게 구성된다. 특별히 음식 문화는 어느 나라이든 자연 조건의 영향과 함께 오랜 역사 속에서 형성되었기 때문에 독특하고 다양한 문화적 차이를 지니고 있으며 이러한 문화적 차이는 냉장고 사용에 있어서 다양한 사용행태를 구분 짓는다. 따라서 본 연구를 통해 식품 종류에 의한 영향뿐 아니라 내부 공간 활용의 패턴, 냉장고 환경 설정에 대한 능동적인 태도, 냉장고에서 제공하는 파티션이나 옵션에 대한 수용 정도, 식품의 정리 원칙에 대한 준수 정도 등에 따른 사용행태 간의 차이점을 발견하고, 차별적 사용행태의 기저에 존재하는 문화적 요인을 분석하여 문화적 차이가 사용자의 경험에 영향을 끼치게 됨으로 인하여 냉장고 디자인에 어떠한 변화를 초래하는지 그 연관성을 밝혀내고자 한다. 보다 실제적인 용도로 활용 가능하도록 냉장고 제작의 상업적인 측면을 고려하여 냉장고 내상의 레이아웃에 중점을 두어 본 연구를 진행하였다. 본 연구는 설문과 현장 관찰을 통해 정량적 관찰을 중심으로 분석하였다. 두 국가의 문화 비교를 위한 설문은 이미 여러 연구자료에 의해 검증된 Trompenaars의 문화 변수를 바탕으로 제작 하였다. 또한 정량적 연구에서 발견될 수 없는 문화권 별 여러 특징들에 대한 데이터를 구체적으로 수집하기 위하여 정성적인 연구 방식의 일환으로 실제 관찰 및 사용자 인터뷰를 실시하였으며, 이를 통하여 현상의 원인 및 사용자의 의도를 파악하도록 연구를 진행하였다.

In this study, the concept of eXtended Reality Devices(XR) is defined, how it is applied by industry and how it will develop in the future, and based on the expanded integrated technology acceptance theory and innovation resistance, We tried to confirm through empirical analysis how the influencing variables affect. We carry out the analysis of the hypotheses using PLS Structural Equation Modeling. According to the empirical analysis results, this study confirms that innovativeness has a significant effect on UTAUT2's acceptance variables(performance expectation, effort expectation, hedonic motivation, price value) for XR devices, and these variables affect attitudes and acceptance of XR. and the pace of change of XR has a significant effect on perceived risk, and the perceived risk perceived by consumers mediates the pace of change and innovation resistance, and has a significant effect on innovation resistance. and innovation resistance to XR devices had a significant negative effect on acceptance. This study has its meaning because it found out that it deals expansively and comprehensively with personal innovation, the UTAUT2's acceptance variables, and the effects of perceived risk factors mediating the pace of change and resistance to innovation. In addition, it suggests that in order for innovative technologies such as XR to advance to the stage of market expansion, it is important to present strategies to reduce resistance to new technologies as much as the value to be provided to consumers.

This study was intended to conduct a prospective study on the P2P Car-sharing service, which will be established as a new business model in the future, by identifying consumers' intention to accept the technology for the P2P-based Car-sharing service that will be introduced and spread in earnest in the future. The main results are as follows. First, the quality characteristics of the P2P Car-sharing service all have a statistically significant positive(+) effect on the perceived usefulness and ease of use of users, and among the quality characteristics, the service characteristics have a relatively strong effect on the perceived usefulness and ease of use, respectively. Second, both perceived usefulness and ease of use had a statistically significant positive(+) effect on users' intention to use P2P Car-sharing service, and ease of use was more dependent on intention to use P2P Car-sharing service. Third, the ease of use of the P2P Car-sharing service had a strong positive(+) effect on their perceived usefulness. As a result of this study, the most important factor to consider in establishing a P2P-based Car-sharing platform is to be constructed in the form of a universal design that prioritizes user convenience rather than usefulness and various functions of the service. It was suggested that UX design should be made, considering the surrounding clues, which are service environment elements.

Platform contrasts with traditional industry in terms of innovativeness as it is rapidly developing with information technology. To redeem preceding researches which have separately focused on either platform acceptance based on technology acceptance model or resistance factors against platform's innovation, this study applied dual factor theory to check the simultaneous influence of enablers and inhibitors on resistance. This study chose purchasers of online used trading platform as a subject of study since it contrasts with other platforms in many characteristics. Based on preceding studies, the moderating effects of their past purchase numbers on the relations between resistance and use intention were also checked. The findings reveal that economic benefit as an enabler had significant negative influence on the resistance, but social influence didn't have expected influence. In case of inhibitors, both perceived complexity and perceived risk had significant positive influence on the resistance. Though resistance had significant negative influence on the use intention, its influence was moderated into the positive direction as users' purchase number increased. Lastly, resistance had mediation effect between antecedent factors (economic benefit and perceived complexity) and use intention.

Today, Software as a Service(SaaS) is being recognized as a key means to enable the innovation of software distribution. Despite the increase in the interest in SaaS, individuals as well as businesses are not yet making an extensive use of it. This research is aimed at identifying and analyzing the antecedents of intentions to use SaaS. We proposed a research model to predict an individual's intention to use SaaS based on the Technology Acceptance Model(TAM). To this end, we conducted a questionnaire survey in which actual software users participated. An empirical analysis has been performed to test the reliability and validity and the hypotheses using SPSS and AMOS software packages. The results of the analysis revealed that functionality, interoperability and economic benefits have positive effects on the intention to use SaaS, while system quality has no significant effect on the behavioral intention. We discussed practical as well as academic implications, and provided research directions.
