Purpose Global fintech industry is proliferating. Although domestic investment in fintech service is also increasing fast, user acceptance of fintech payment service seems slower than expected. Previous fintech literature mainly focuses on overall characteristics and technical aspects of fintech including security issues and explores factors affecting the service adoption. This study aims to examine crucial factors affecting user's resistance intention to fintech payment service adoption. The research model was formulated based on innovation diffusion theory and status quo bias theory and validated empirically. Design/methodology/approach The proposed research model was empirically validated with 149 responses from college students who have used fintech payment service. The component-based SEM was employed for data analysis. Findings The significant findings are as follow. First, compatibility has significant negative effect and complexity, and perceived risk has a positive effect on user resistance. Second, institutional trust does not show a significant effect on user resistance but has an indirect effect through the mediation of trust in service provider. Finally, trust in service provider shows the significant negative effect on user resistance.

Currently, various discussions are underway to establish a more advanced management system for public rental housing. Also, it calls for improvement methods for problems arising in management of the current rental housing system. In this regard, this study aims to evaluate determinants that affect user acceptance intention of blockchain technology to implement a new system that complements drawbacks of the current public rental housing system. The study uses the Unified Theory of Acceptance and Use of Technology (UTAUT) as a theoretical model; the study model utilizes three UTAUT variables -performance expectancy, social influence, and Facilitating conditions-, applies security, availability, and reliability that are perceived from blockchain technology as external parameters to facilitate understanding of user acceptance intention of blockchain technology, and evaluates whether innovativeness can regulate the influence of performance expectancy, social influence, and Facilitating conditions on user acceptance intention of blockchain technology. Based on the significant survey result where 274 IT technicians participated, the study applies structural equation modeling to explore structure of user acceptance intention in the blockchain-based management system for public rental housing. As a result, security-reliability and availability are found to factors as determinants for user acceptance intention, affecting implementation of the public rental housing management system, while innovativeness shows no significant statistical results related to regulation effect. This study has implications in that it understands characteristics of blockchain and empirically analyzes the relationship between the characteristics and acceptance intention to enable blockchain's contribution to activate the public rental housing management system in the future.

사이버모욕죄 보도에서 한국 언론은 핵심 가치(범죄로부터 안전 vs 표현의 자유)와 귀인 양식(일화적 vs 주제적 귀인)측면에서 상반된 프레임을 구축하여 경쟁한 것으로 나타났다. 본 연구는 뉴스 텍스트 내에서 프레임을 구성하는 주요요소로서 핵심 가치와 귀인 양식에 주목하고, 구체적으로 가치가 신념에 대한 중요도 인식과 정서적 반응을 통해 사이버모욕죄에 대한 의견에 미치는 영향력을 탐구하였다. 또한 귀인 양식이 정서적 매개 과정을 통해 의견에 영향을 미치는 과정도 분석되었다. 온라인 실험 결과, 뉴스 프레임에 함축된 핵심 가치가 무엇이냐에 따라 그에 관련된 신념의 중요도가 변화했으며 이는 부분적으로 사이버모욕죄에 대한 의견에 유의미한 영향력을 행사한 것으로 나타났다. 탐색적인 관점에서 분석된 핵심 가치의 정서적 효과는 미약한 수준에서 발견되었는데, '범죄로부터 안전'이라는 가치는 악플러에 대한 분노를 다소 강화시켰으며 이러한 분노 정서는 사이버모욕죄 찬성 의견을 강화시키는 경향을 보였다. 한편, 개인적귀인이 사회적 귀인에 비해 '문제적 개인들'에 대한 분노 정서를 강하게 초래할 것이라는 가정은 입증되지 않았으나, 일화적 프레임은 주제적 프레임에 비해 더 효과적으로 핵심 가치가 함축하는 방향으로 의견에 영향을 미쳤다.
