As smart devices have proliferated and mobile networks have accelerated, various wired IT(Information Technology) services are transplanted in wireless environments. Cloud computing service, enabling individual users or firm users to download data from a server and upload data after manipulating data, is also available in mobile devices. Unlike cloud service in wired network environments, mobile cloud service provides differentiated aspects in mobility, security issues caused by persistent connection to networks. In this paper we aim to analyze the factors affecting the user attitude and their structural relationships towards mobile cloud service use. We extend TAM(Technology Acceptance Model) to consider the characteristics of mobile environments. Research findings, analyzed by SEM(Structural Equation Model), are explained and practical implications are presented with concluding remarks.

The accelerating growth in Technology-Based Self-Service (TBSS) today is giving rise to questions about the acceptance of such forms of service delivery by all kinds of consumers. Using the Technology Acceptance Model (TAM) and TBSS quality evaluation model as a theoretical framework, this study investigates the effects of perceived usefulness, perceived easy of use, enjoyment of users acceptance of TBSS and self-monitoring as a individual variable. The results lend support to the hypothesist. Implications for service practitioners as well as directions for future research are discussed.

This study aims to understand crucial factors affecting user's Fintech payment service adoption. On the basis of innovation diffusion theory and prior Fintech literature, this study classifies the influence factors of users' adoption of Fintech payment service into two dimensions - service dimension containing complexity, perceived benefit, trust in service provider and user dimension containing personal innovativeness and security breach experience. The data analysis results using binary logistic regression shows the negative direct effects of perceived risk, complexity, security accident experience on user's service adoption are statistically significant. Personal innovativeness has a positive effect on user's Fintech payment service adoption. The moderation effect of security accident experience is also significant at p<0.05.

This study explores the factors which affect user acceptance for Robo Taxi, an electricity-based Autonomous Vehicles based on a Value based Adoption Model. The three main factors of benefit (usefulness and enjoyment), sacrifice (technicality and perceived fee level), and user experience about mobility services such as car sharing, taxi, and autonomous vehicles, were finally selected as independent variables as a influential factors on perceived values and adoption intention of Robo taxi. The study found that usefulness, enjoyment, and perceived fee had a significant effects on adoption intention, and some user experiences had a significant effect on benefit factors. This study has important implications for incorporating the Value-based Adoption Model results into the service design for the activation of Robo taxi, and furthermore, they can provide a theoretical basis for effective use of the research findings.

In this paper, we attempt to investigate the factors influencing usage and acceptance of ubiquitous services in campus, based on the Technology Acceptance Model(TAM). This study conceptualizes and develops three dimensions of u-Services, such as real time service, information security, customization service, and tests the relationship among u-Services, perceived usefulness and perceived ease of use, and intention to use. Data were collected from 162 respondents in K-University and research model was tested using multiple regression analysis. As a consequence, this study found that customization service is an important factor which is influenced to perceived usefulness and perceived ease of use.

In the 1st half of 2009, Hana Bank was first to launch the smart banking service in Korea and thereafter, the smart banking system spread rapidly within Korea. Until 2010, the users have reached about 2,610,000. So, for more profit, how to make the smart banking early-adopters continually use the service has became the key issue. But, there are only few researches on continuous acceptance of smart banking service now. The aim of this study is to find out factors influncing continuous acceptance of smart banking service and the appropriate model for it. After analyzing the market status of smart banking service, Security, Service Scalability and UI convenience were chosen to be the most important independent variables. And research model was designed based on Expectancy Disconfirmation Theory and Post Acceptance Model. To verify the model, a survey targeting at smart banking service users was implemented.

This study was investigated the Influential Factors on Chinese Consumer's Usage Intention of Mobile Internet Service. The results of this study are as follows. First, Usefulness, Easy of Use, Subjective Norm, playfulness are positively related to Perceived value. Second, perceived risk is negatively related to Perceived value. Third, Perceived value is positively related to Intention of Mobile Internet Usage. Based on these results, managerial implications for Mobile internet service are discussed. Lastly, the limitation of this research and further research issues are suggested.

The advancement of the information technology provides a wide range of corporate to cope with new business environments that are different in size, life and operation conditions. The Research methodology used in this study is Technology Acceptance Model. The Study Method are mainly survey and questionnaire. The major result of article can be summarized. Its are as the follows: This paper ware investigated the determinants of 'port service quality', 'perceived usefulness', 'perceived ease of use', 'utilization intention', 'practice use'. There are 400 sended samples and 150 returns, 173 of them are analyzed on a port utilization using TAM model. 1. The Port service quality are found to have a positive effect to 'perceived usefulness', 'perceived ease of use', 'utilization intention' 2. The perceived ease of use are found to have a positive effect to 'perceived usefulness', 'utilization intention' 3. The perceived usefulness is found to be positively related to 'utilization intention' 4. The utilization intention is found to have a positive effect to ''practice use' we hove to provide useful contribution to increase the Korea ports' competitiveness in introduction of port information system. In addition, in order to port development offer some insight in further research.

Recently, many business organizations have been increasingly expanding the utilization of the intelligent chatbot services for effective customer relation management. The purpose of this study is to empirically investigate the factors which affect the use of the intelligent chatbot services. Above all, the research model and the hypotheses were derived through reviewing the major relevant theories such as UX(user experience) theory(Honeycomb model), TRA(theory of reasoned action), TAM(technology acceptance model) and ETAM(extended TAM). And then, structural equation analyses using SmartPLS 3.0 for 233 valid questionnaires replies collected through the field survey was performed to test the hypotheses. Theoretically, this study can contribute to providing the conceptual framework with regard to enhancing the use of intelligent chatbot services. And practically, this study sheds new light on suggesting the guidelines to designing the UX(user experience) of the intelligent chatbot services.
