This study is designed to test the effects of innovativeness, information dependency, informative sufficiency, and review reliability on perceived usefulness, perceived ease of use, and eventually continuous use in mobile bakery applications and to provide useful information for the bakery industry. A total of 500 questionnaires were distributed for data collection from September $1^{st}$ to $30^{th}$ in 2014. Out of 455 returned questionnaires, 441 were useable. Statistical techniques utilized in the study were a factor analysis, reliability tests, and a covariance structure analysis using SPSS 18.0 and AMOS 18.0. The results were as follows: first, innovativeness had significant effects on perceived usefulness and perceived ease of use. Second, information dependency had significant effects on perceived usefulness and perceived ease of use. Third, informative sufficiency had significant effects on perceived usefulness and perceived ease of use. Fourth, review reliability had significant effects on perceived usefulness and perceived ease of use. Fifth, perceived ease of use had a significant effect on perceived usefulness.

This study identifies the effects of HTML5 service quality on the use intention of smart learning and present the policy implications through empirical studies. This study select assurance, reliability, tangibles, responsiveness, empathy as independent variables of HTML5 service quality and also select perceived usefulness, degree of perceived ease of use as parameters and select use intention of smart learning as dependent variables. The control variables such as learning devices, service, learning place, use age, use times are adapted. As a result of analysis by applying the structural equation model, it was estimated that the reliability of HTML5 service quality, tangibles affect negatively on perceived ease of use, but reliability, assurance, tangibles, empathy, responsiveness of HTML5 service affect positive impacts on perceived usefulness, and also certainty, empathy, responsiveness was identified as positive impacts on the perceived ease of use. It was proven that perceived ease of use effect positive on the perceived usefulness and also usefulness or ease to use have positive effects on the usage intention of users.

A research model was created in order to explore the factors on use intention based on Technology Acceptance Model and considered factors of Mobile-Blog Characteristics (Participation, Sharedness, Immediacy) and factors of Mobile-User Characteristics(Innovativeness, Familiarity). With 165 people as specimens for empirical analysis, The results were as follows: first, factors of Mobile-Blog Characteristics had a positive influence upon Perceived Ease of Use and Perceived Usefulness. second, factors of Mobile-User Characteristics had a positive influence upon Perceived ease and Perceived usefulness. third, Perceived ease had a positive influence upon Perceived usefulness and Perceived ease and Perceived usefulness had a positive influence upon use intention. This study suggested the strategic implications to promote customers use intention after analyzing the critical factors that mobile-blog made influence on them.

In this study, we explored Technology Acceptance Model(TAM) to introduce Blockchain technology in the medical field. It extracted five external variables(Security, Availability, Reliability, Diversity, Economic feasibility) through previous studies. It set the study model for a path to acceptance intention through the information reliance of recognized easiness and recognized usefulness. As results of empirical analysis, H1-1(Security →Perceived Easiness) was rejected. H1-2(Availability→Perceived Easiness), H1-3(Reliabilit→Perceived Easiness), H1-4(Diversity →Perceived Easiness), H1-5(Economic →Perceived Easiness) were adopted. Hypothesis 2 was a relations between Blockchain's characteristics and Perceived usefulness, all the Hypothesis were adopted. Hypothesis 3 and Hypothesis 4 indicated that H3-1(Perceived Easiness →Perceived usefulness) was rejected but H3-2(Perceived Easiness → information reliability), H3-3(Perceived usefulness → information reliability), and H4(information reliability→acceptance intention) were all adopted. It was confirmed that it is important to emphasize the importance of stability to introduce block chain technology to medical centers, but it was necessary to use a design that can increase the easiness from the prospect of users.

The purpose of this study is to propose implications that can be effectively applied to the educational field by exploring the intention to use of augmented reality-based educational contents for college students. To this end, a survey was conducted with college students, and confirmatory factor analysis, correlation analysis, reliability analysis, and path analysis were performed using the SPSS 21.0 program and the AMOS 21.0 program. The results of the study were presented as follows. First, individual innovativeness influenced positively on perceived ease of use, perceived usefulness, and perceived enjoyment. Second, social influence influenced positively on perceived ease of use, perceived usefulness, and perceived enjoyment. Third, perceived enjoyment influenced positively on perceived usefulness. Fourth, perceived ease of use influenced positively on perceived usefulness and perceived enjoyment. Fifth, except for perceived ease of use, perceived usefulness and perceived enjoyment influenced positively on intention to use.

The purpose of the study is to establish a successful the national tax service electronic document system and suggest an application method by investigating relationships among perceived availability, perceived usefulness and system acceptance suggested by Technology Acceptance Model(TAM). As a result, perceived availability and perceived usefulness were playing roles as mediums on the process of accepting an tax electronic document system, and information quality of the electronic document system turned out to influence on perceived availability and perceived usefulness. And perceived availability turned out to influence on perceived usefulness. This suggests that the more tax officials feel comfortable in using an tax electronic document system, the more useful they perceive it is.

In this study, the Technology Acceptance Model (TAM) was applied to explore the process of using card news. Card news users are found to be active in searching and selecting appropriate news for themselves, information seeking style and news literacy were established as antecedent variables that can influence card news usage. A survey of 400 university students with experience of using card news was conducted. For statistical analysis, SEM was conducted. The analysis showed that information seeking style significantly affects perceived ease of use (PEU) and that news literacy influences neither PEU nor PU. PEU was found to have a significant effect on PU, and both PEU and PU had a significant effect on recommendation intention.

기대일치이론에 기초한 기대일치모형은 정보시스템 연구 분야에서 정보시스템의 지속적인 사용 혹은 사용의도를 설명하는 핵심 이론으로 언급되어 왔다. 이러한 기대일치모형과 더불어 최근에 정보시스템 분야에서 주목을 받고 있는 또 다른 개념은 자동화된 행동 경향을 의미하는 ‘습관’이다. 본 연구에서는 이러한 두 가지 개념들을 기초로 모바일 인터넷 서비스에 대한 지속적인 이용 상황에서 습관과 기대일치모형을 통합하는 시도를 하였다. 이에 일치, 지각된 유용성, 지각된 사용 용이성, 습관 등의 수용후 신념, 이용자 만족, 지속적 이용의도로 구성된 연구모형을 구성하고 이를 검증하였다. J도내 250명의 대학생들을 대상으로 설문자료를 수집하여 분석한 결과, 기대일치와 지각된 유용성이 모바일 인터넷 서비스의 이용자 만족에 대한 주요 요인으로서 나타났다. 또한 지각된 유용성, 이용자 만족, 습관은 모바일 인터넷 서비스에 대한 지속적 이용의도를 결정하는 주요 요인으로 나타났다. 반면에 지각된 이용 용이성은 이용자 만족과 지속적 이용의도 모두에 대하여 아무런 관련성이 없는 것으로 나타났다.

This study analyzed the effect of app characteristics of the handicapped library on user satisfaction and intention to reuse using the technology acceptance model. As a result, the app's accessibility, convenience, innovation, and reliability have a significant effect on perceived usefulness, and instant accessibility, accuracy, and interactivity have no significant effect. The characteristics of all apps were analyzed to have a significant effect on perceived ease of use. The regression model for perceived ease of use and perceived usefulness was statistically significant. It was found that perceived ease of use and perceived usefulness had a positive effect on user satisfaction and satisfaction was intended to be reused.
