본 연구는 모바일 메신저 애플리케이션과 사용자 사이에 인지된 상호작용성이 어떻게 즐거운 감정과 지속적 사용의도를 유발시키는가를 검증하기 위하여 수행되었다. 본 연구는 메신저 애플리케이션에 대한 사용자의 인지된 상호작용성이 제어, 공유, 응답 요인에 의하여 형성된다고 보았다. 인지된 상호작용성, 즐거움, 사용의도 사이의 관계는 PAD 감정모형, 합리적 행동이론, 그리고 계획된 행동이론을 이용하여 연구가설로 설정되었다. 연구모형을 검증하기 위하여 한국과 중국에서 총 481개의 설문 데이터가 수집되었고, 구조방정식을 이용하여 가설을 검증하였다. 연구결과, 인지된 상호작용성인 공유와 응답 요인은 즐거움에 긍정적 영향을 미칠 뿐만 아니라, 사용의도에도 유의한 영향력을 가지는 것으로 도출되었다. 그러나 제어는 사용의도에는 긍정적 영향을 주지만, 즐거움에는 유의한 영향력을 가지지 않는 것으로 도출되었다. 그리고 즐거움과 사용의도 사이에는 긍정적 인과관계가 존재하였다. 본 연구는 부가적으로 한국과 중국 사용자들 사이의 차이점을 탐색하기 위하여 다중집단 차이분석을 실시하였다. 연구 결과를 바탕으로 모바일 메신저 서비스를 제공하는 기업들에게 인지된 상호작용성이 가지는 인과적 영향력과 한국과 중국 사이에 존재하는 경로계수 차이에 대한 시사점을 논의하였다.

Purpose: Present study was designed to examine the casual relationships among service quality, self-efficacy, perceived usefulness, user satisfaction and Continuous Usage in new technology-based banking system. Also, we intended to testify the moderating effects of user experience period in causal model. We applied path analysis model in order to test the hypotheses and research model. Methods: Survey tool, that is, questionnaire has obtained validity through literature survey, exploratory survey and pretest and sample 279 was selected. For statistical treatment of pretest and main analysis, SPSS20.0 and AMOS 20.0 were employed and structural equation model was employed as analysis method. Results: Result of this study shows as follows. All factors have an effect on user satisfaction and Continuous Usage, and we found that user experience period played moderating effect in causal relationship. Therefore, new technology-based banking system is found that the determinants of continuous usage intention is different according to the user experience period. Conclusion: Present study shows that self-efficacy in via of user experience period, there is a need to emphasize that the main consideration factor new technology-based banking system. However, present study has some limitations to additionally research in the future.

AI assistant, a software interface designed to interact with a user in a natural way and perform specific tasks on the user's behalf, receives increasing attention from both scholars and practitioners. While most of the literatures explain about technical aspects, little is known about the social and psychological factors that intimately influence consumers when using it. This study sheds light on the reason people use AI assistant and how perceived values influence on intention of continuous usage. A total of 361 AI assistant users participated in an online survey, and all were recruited from a major online panel in South Korea. The results from the principal component analysis suggest five social and psychological motives: self-expression, quality of life, entertainment, information, and compatibility. In addition, perceived values, informativeness, entertainment, and trustworthiness, positively predict the intention to use AI assistant. This research provides theoretical contributions from finding motivations of AI assistant usage and from the effects of perceived values on the intention to use it. Practical implications should not be overlooked in this ever-expanding AI industry.

Contemporary smartphone competition is generally described as the battle between Apple's proprietary platform and Google's open platform. However, this competition is not limited within smartphone adoption itself. User's pre-adoption of one mobile platform via smartphone can be connected to the post-adoption of the same mobile platform based on the other smart devices (e.g. smart pad). In this study, we investigate whether user's preference to a certain platform is persistent over mobile ecology, from the pre-adoption of one smart device to the post-adoption of following devices. For this investigation, we adopt the dual-model as the ground theory, where post-adoption of IT product is explained by both dedication and constraint factors. The empirical testing first evidences that dual model works well as our research model for identifying the reasons of post-adoption. Next, we group our data into two parts in order to compare the switching behavior of iPhone users and Android phone users. iPhone users show much lower switching rate to Android based smart pads, while Android phone users show higher churn rate to iPad (49.3% : 96.3%). Especially, satisfaction showed much stronger effect than switching cost on the continuing intention of existing platform, when the analysis is given to the iPhone user's group. From this result, we can conjecture the relatively stronger loyalty of iPhone users. More managerial implications on the mobile platform strategy are driven.

소셜 네트워크 게임이란 소셜 네트워크 서비스 플랫폼을 기반으로 하여 사용자 참여 및 관계 맺기를 활용한 사회적 인맥 기반 형태의 게임을 말한다. 본 연구는 HCI 분야에서 제시하는 가치모형을 중심으로 SNG의 지속적 사용의도에 영향을 주는 기능적, 유희적, 사회적, 개인적 가치 요인을 검토하였다. 분석 결과 유희적 가치와 기능적 가치가 지속적 사용의도에 영향을 주는 것으로 나타났으며, 사회적 가치, 개인적 가치는 유의한 영향을 주지 않는 것으로 나타났다. 이는 SNG의 서비스에 있어서 게임의 재미적 요인과 쉽고 편리한 인터페이스는 주요한 요소이지만, 이용자들의 사회관계적 동인은 큰 의미가 없음을 의미한다.

본 연구는 기대불일치이론을 토대로 위치기반 서비스에 대한 개인의 사전 기대와 성과 평가 간의 불일치 정도를 살펴보고, 기대불일치가 서비스 만족도와 지속 사용 의도에 미치는 영향력을 살펴보았다. 본 연구는 SPSS 19.0과 Amos 21.0를 활용하여 스마트폰 위치기반 서비스에 대한 기대불일치, 만족도, 지속 사용 의도 간의 관계를 분석하였다. 본 연구의 결과를 요약하면, 첫째, 기대불일치가 서비스 만족도와 지속 사용 의도에 영향을 미치는 것으로 확인되었다. 둘째, 기대불일치가 지속 사용 의도에 미치는 영향력이 만족도에 의해 매개될 수 있음이 확인되었다. 셋째, 서비스 신뢰에 의해 기대불일치, 만족도, 지속 사용 의도의 관계가 조절될 수 있음이 확인되었다. 이러한 결과는 위치기반 서비스의 지속 사용 의도를 향상 시키거나 감소시키는데 기대불일치와 만족도가 중요한 영향을 미칠 수 있음을 시사한다. 향후 연구에서는 위치기반 서비스에 대한 소비자들의 기대 요소들을 세부적으로 파악하여, 어떠한 기대 요소들이 만족도와 지속 사용 의도에 영향을 미치는지 확인하는 연구가 필요하다.

Purpose The number of Tablet PC users has recently increased in steep, which started to offer media companies more opportunities to enter into a new business field. Based on Information System Success model, this study finds that tablet magazine's quality factors influence perceived usefulness, user satisfaction and intention of continuous use. Design/methodology/approach We conducted a survey for 20-40's Tablet PC users. After pilot study, we analyzed the main survey data by using SPSS 18.0 and AMOS 18.0, and employed structural equation modeling to test the hypotheses. Findings Our research results are summarized as follows : First, information quality has a positive impact on user satisfaction, but not on perceived usefulness. Second, service quality has a positive impact on perceived usefulness, but not on user satisfaction. Third, perceived usefulness positively influences user satisfaction. Fourth, user satisfaction positively influences the intention of continuous use. In particular we found that Tablet PC usage experience had a moderating effect on the relationship between perceived usefulness and user satisfaction.

In the past days, most of studies about users' behavior in online environments have been mainly focused on the adoption of website and internet shopping or shopping mall. But the generic model of website usage behavior has not been made and the leading theory of website usage behavior has not been existed. The purpose of this study consists of two parts: (1) to find the determinant variables of the website users' continuous using Intention in a certain website, (2) to examine the relative influences of the variables influencing the users' behavior in online environments. The framework of this study is based on the combination of some theories - Davis(1989)'s TAM, Fishbein(1975)'s TRA, Hoffman et al.(1997), Schneiderman(2000), Yoon(2002), Lee and Turban(2001), Sultan et al.(2002), Shankar et al.(2002a, 2002b), McKnight et al.(2002), Chen and Dhillon(2003), Heijden(2003) and so on. Major findings of this research are summarized as fellows: First, determinant of website continuous using intention was affected by 1) the-attitude and 2) the trust of the website except of perceived usefulness. Second, the website attitude was affected by the perceived usefulness, design, experience, reputation. But perceived ease of use did not affect the website attitude. Third, the website trust was affected by the perceived usefulness, perceived ease of use, design, experience of website. But the reputation of website did not determine the trust of Website in this research model.
