Recently, mobile marketing is becoming one of the major topics of interest to the marketing discipline. Emerging from rapid developments in mobile technology, it has created opportunities for new and innovative mobile services. Also, it is enabling to conduct always-on connections that consumers can interact anytime and anywhere. Especially, mobile devices place themselves to the core means of mobile-commerce which to execute a function as a distribution channel in mobile environments. Although the adoption researches about innovative services or technologies had executed in marketing areas over the past decades, most researches just expanded or modified existing theories and explanation models. There has been little study on the comprehensive and systematic review of adoption process. Therefore, it deserves to be considered prior usage experiences of the existing channels(CL) and attractiveness of the new channel(CLalt) based on social exchange theory. In order to address this void, this study unifies components of perceived attributes in the each dimensions (ie. benefit, cost, and risk dimensions) and explores prior usage experiences of the existing channels on adoption intention in electronic financial service channels through developing comprehensive model and employing empirical test for the hierarchy of effects model. Based on these empirical results, this study suggests managerial implications for new channel management in electronic financial service areas by focusing on the prior usage experiences of the existing objects on adoption intention and perceived attributes of ubiquitous-based mobile service channel.

Sharing economy services are expanding, as the efficiency of the resources is enhanced by sharing the resources of the individual consumers and also the direction of consumption is changed to fulfill needs of individual. Therefore, this paper develops the empirical analysis model by considering the features of sharing economy services, and conducts study by utilizing the extended TAM by adding price sensitivity, reliability and perceived enjoyment to TAM in order to analyze the factors that affect the use intention of sharing economy services and to reflect the distinctiveness of sharing economy services. The results of the analysis showed that price sensitivity, self-efficacy, technology innovation, reliability, perceived usefulness, perceived ease of use, perceived enjoyment and use intention are affected in different ways. This study is able to provide clear understanding for use intention of sharing economy services, also implications for expanded use intention to the consumers.

본 연구의 목적은 공항 내 혁신시설에 대한 공항이용객의 평가를 통해 혁신적 서비스 양상과 기틀을 파악하는 것이다. 본 연구는 소비행동의 관점에서 공항이용객의 추구 혜택, 지각된 혁신성, 수용 의도, 구조화에 대한 욕구 등 4가지 개념의 이론에 근거하여 수행되었다. 공항의 혁신시설을 이용한 경험이 있는 299명 성인을 대상으로 2022년 7월 5일부터 9일까지 자료를 수집하였다. 수집된 자료는 공항이용객의 추구혜택과 수용의도 간의 관계에서 공항이용객의 지각된 혁신성의 매개효과 및 공항 이용객의 추구혜택과 지각된 혁신성 간의 관계에서 구조화에 대한 욕구의 조절효과를 분석하였다. 연구 결과, 공항이용객의 추구 혜택은 수용 의도에 긍정적 영향을 미치고, 지각된 혁신성은 수용 의도에 긍정적 영향을 미치는 것으로 나타났다. 이러한 결과는 공항 이용객의 욕구에 근거하여 혁신적인 기능을 향상시켜야 함을 시사한다.

최근 스마트폰, 태블릿PC 등 스마트 단말기의 보급 확대로 전자책 시장이 국내외에 지속적으로 성장하고 있지만, 실상은 생각보다 더디게 진행되고 있다. 2015년 전자책 독서실태 결과 지난 1년간 전자책 독서량은 지난번 조사에 비해 0.2권 감소한 1.4권에 그쳤으며 전자책 구독층이 가장 많은 10~20대의 전자책 이용 비중도 줄었다. 이에 본 연구는 대학도서관의 전자책 서비스에 있어서 지각된 가치와 지각된 위험을 기술수용모델(TAM)에 추가하여 서비스 이용자의 수용 후 지속적 사용의도를 실증적으로 분석하고자 한다. 이를 통해 향후 대학도서관 전자책 서비스, 더 나아가 정보서비스의 개발과 보급에 있어 유용한 시사점을 제고하고자 한다.

The purpose of this research is to investigate the effects of brand extension on original brand in mobile market. TAM (Technology Acceptance Model) was used in current research to verify the 'intention to use of mobile service', and 'perceived usefulness', 'perceived ease of use', and the effect of 'extended brand's intention to use' on continuous 'intention to use in original brand' are verified in the process. According to the results, TAM was found to be appropriate to verify the intention to use of mobile service. Also by verifying the effect of decision factor, it is found that perceived ease of use have positive(+) influence on continuous intention to use of original brand. According th this finding, marketers will be able to understand better in performing strategies in mobile service environment.

In this paper we consider Internet Protocol Tele-Vision (IPTV) Service that started recently in Korea. IPTV makes it possible to watch high quality TV programs and a lot of multimedia contents with TV by way of Internet. The service providers are interested in the factors that influence the diffusion of new service such as IPTV. We therefore search the functional-attribute that would influence the acceptance of IPTV service, and propose a model for analyzing the relationship between the attributes and the intention of buying. The model is based on the extended Technology Acceptance Model (TAM). Survey results show that the significant functional attributes influencing the intention of buying are contents variety and convenience.

Blockchain is a core technology to solve personal information leakage and data management issues, which are limitations of existing Genomic Sequencing services. Due to continuous cost reduction and deregulation, the market size of Genomic Sequencing has been increasing, also the potential of services is expected to increase when Blockchain's security and connectivity are combined. We created our research model by combining the Technology Acceptance Model (TAM) and the Innovation Resistance Theory also analyzed the factors affecting the acceptance intention and innovation resistance of the Blockchain Based Genomic Sequencing Information Platform. A survey was conducted on 150 potential users of Blockchain and Genomic Sequencing services. The analysis was conducted by setting the four Blockchain variables: Security, transparency, availability, and diversity). Also, we set the Perceived Usefulness, Perceived risk, and Perceived Complexity for Technology Acceptance and Innovation Resistance variables and analyzed the effect of the characteristics of the Blockchain on acceptance intention and innovation resistance through these variables. Through this analysis, key variables that need to be considered important to reduce resistance and increase acceptance intention could be identified. This study presents innovation factors that should be considered in companies preparing a new Blockchain Based Genomic Sequencing Information Platform.

Cloud storage service has the potential to be a core infrastructure for the future mobile and Internet service; thus related service providers have been investing in it and trying to attract as many users as possible. In addition, those need to find out what motivates the users to keep using their service not only to attract new customers but also to secure their subscribers. Therefore, this study will examine its relationship with user's motivation based on the extended TAM model with external variables for objective research about continuous use of cloud storage service. As a result, it was found that personal innovativeness, self efficacy, functional attributes, and psychological switching cost influence the continuous use of cloud storage service. Also, it is expected they can guide service providers to the right track when setting up their business strategy in the future.

The purpose of the study is to examine a structural relationship among mobile self-efficacy, mobility, perceived ease of use, perceived usefulness, and intention to use of a mobile learning service using technology acceptance model. The result revealed that mobile self-efficacy, mobility had a direct effect on perceived ease of use. Second, mobile self-efficacy, mobility, perceived ease of use had a direct effect on perceived usefulness. Third, mobile self-efficacy, mobility, perceived usefulness had a direct effect on intention to use of a mobile learning service. However, perceived ease of use did not have a effect on behavioral intention of mobile learning service.
