본 연구는 모바일 간편결제시스템에 대한 신뢰 형성에 영향을 미치는 주요 요인을 개인적인 측면과 시스템적인 측면에서 도출해내는 것에 목적을 두고 있다. 개인적 특성으로는 개인의 혁신성과 익숙함이 포함되고, 시스템적 특성으로는 편의성, 접근성, 호환성이 포함된다. 또한, 이러한 개인의 혁신성과 익숙함, 편의성, 접근성, 호환성은 사용자의 신뢰에 영향을 끼치게 된다. 사용자의 신뢰향상은 모바일 간편결제시스템의 지속사용을 이끄는데 중요한 선행변수로 작용될 수 있다. 본 연구를 위해 부산과 대구지역의 대학생을 대상으로 설문을 실시하였으며, SPSS와 PLS를 이용해 자료를 분석하였다. 분석결과, 개인측면의 요인과 시스템적 요인이 사용자의 신뢰에 영향을 끼치는 것으로 나타났다. 이러한 연구결과는 모바일 간편결제시스템의 신뢰형성과정을 살펴볼 수있다는 점에서 의의를 가지게 된다.

Recently, there is a trend to introduce a reliability approach to the design of al large scale improvement of weak ground due to the uncertainty of the influence factors in the consolidation. Since the reliability analysis is not easily adopted to geotechnical engineers because of some difficulties in working up the theories, Duncan(2000) proposed a simplified method for using reliability method to goetechnical problems. In this study, the applicability of Duncan's simplified reliability approach is evaluated by comparing the traditional reliability results with Duncan's. In the sensitivity analysis, the two results were quite similar. However, the probability of failure showed an error range of 20~50% and further Duncan's approach could not make a distinction for the distribution of geotechnical random variables. The simplified reliability method seems to be used properly in preliminary design if it is used supplementary with the deterministic method.

Recently, various payment services using mobile terminals are emerging and many users are using this service. This study is an empirical study on the effect of system factors(convenience, reachability, compatibility) of mobile simple payment service on trust, positive affect, mediated by customer perceived risk. A survey was conducted for this study, and a structural equation model was analyzed with PLS. Results showed that convenience, accessibility, and compatibility affect risk, and risk affects trust and positive affect.

The various models that estimate the reliability of application software system had been made. But most of the existing models are inconvenient to industrial fields because so complicated mathematic methods as method of estimation parameter have been used. The two purposes of this paper are to develop the reliability estimation model which was easily applied to industrial fields, and to prove no differences between the existing models and the developed model. Therefore the reliability of software system and handled informations are upgraded by far.

The current study examines whether consumers' perceived usefulness of and trust in the integrated mobile payments services positively influence consumer loyalty to the payments system as well as to the online shopping websites where they have used the payments system. Moreover, the study investigates the effects of individual characteristics and brand awareness of the provider of mobile payments on perceived usefulness and trust. Online survey was administered to consumers ranging in age from 20s to 40s. Data analysis reveals that as consumers' perceived usefulness of and trust in the mobile payments system positively influence consumer loyalty to mobile payments and shopping mall websites. The results of the study suggests that e-commerce's user interface design, particularly the transaction system, should receive greater attention as a basic web element of e-commerce building rather than a set of plug-ins or so.

The purpose of this study is to design the easy payment service research model and to find the influencing effect on the intention for the reuse of easy payment service by analysing the factors such as the social influence, the promotion condition, the security and the convenience as UTAUT model has. Also the research model employs the trust and the user satisfaction as parameters. The result shows that even though people feel the trust due to the convenience by the social influence, it has a negative influence on the user satisfaction if the risk recognized in the easy payment service and the weakness in the security are anticipated. The results of this study are academically meaningful as they established the research model for the easy payment service and the theoretical basis of the easy payment service area; they have provided the various practical implications.

This study sought to improve the mobile easy payment services available in Korea by conducting a comparison analysis of Kakaopay, the front-runner of the mobile easy payment services in Korea's FinTech industry, compared to Naverpay, the relative newcomer in the industry. The services were compared by analysing users' experience. First, a literature review on the theoretical background of the FinTech and its characteristics was performed. Secondly, a survey created by reframing the six elements of the "Creating Pleasurable interfaces Model" by Stephen Anderson was conducted. In result, Kakaopay showed limited applicability caused by the lack of affiliated stores and it also showed the lack of reliability due to errors and cancellations related to the payments. It was shown that Naverpay also needs to make an effort to improve the reliability by minimizing errors in the use of the program and payments. This current study aimed to contribute as a resource which can be used, in the future, to improve the users' experience in FinTech services offered in Korea and also to invigorate the Fintech industry.

In this study, the emotional reaction process and the cognitive reaction process were divided into the process of building trust in order to form a continuous use intention in the process of using the mobile simple payment system. We examined the process by which various external factors generate continuous use intentions, that is, behavioral responses through the process of each reaction. External factors were divided into social factors, systemic factors, and social factors. Among them, system factors were social norms and images, and systemic factors were simplicity and accessibility. And the social factors consisted of security and compatibility. And the emotional response was set as pleasure and emotional trust, the cognitive response was cognitive trust, and the final dependent variable was set as continuous use intention. A survey was conducted for model analysis, and the analysis results were derived using PLS.

This research deals the method to assess the validity and reliability of students' evaluation for lectures. Most papers for student's evaluation have focused the procedures for controlling the external effects, but this paper is trying to answer for "How reliable is the student rating?" An empirical study shows that the evaluations in Jeonju University have the fair validity and reliability. The generalizability theory is suggested to obtain the more comprehensive results rather than Cronbach's alpha to examine internal consistency.

인체통신 기술은 유선통신 기술에서와 같이 기기들 간의 연결을 위한 다양한 형태의 케이블이 필요하지 않으므로 기존 유선통신 기술에 비해 편리한 우월성을 가진다. 그렇지만 보안성과 신뢰성은 유선통신의 장점을 넘을 수는 없을 것이다. 무선통신 기술은 초기 네트워크를 구성하기 위하여 서로 복잡하게 주고 받는 절차단계가 필요한 반면, 인체통신 기술은 사용자의 간단한 접촉만으로 통신이 서로 이루어지기 때문에 보다 더 간편하게 연결되며, 사용자 중심의 서비스를 용이하게 제공할 수 있다. 본고는 최근의 인체통신 기술의 기술 동향과 시장 전망 및 표준화 동향을 살펴보고자 한다.
