Mobile payment service is a new innovating technology in the micro payment industry. Although it emerged only one or two years a9o in Korea, it is now highly used and prospered by many online companies. Traditional studies concerning the electronic payment system are usually about the payment process itself, so they stressed the security or the robustness of the process. The study from the angle of behavioral science seldom exists. This article describes the phenomenon of technology adoption with a particular focus on telephone Payment service. The article identifies which characteristic of the telephone payment service affects to the user status (user, non-users). To do this, this article mainly used Roger's Technology Acceptance Model and some characteristics are added to the model. The most important perceptual characteristic that affects to the user status was not security, but ease of use-the telephone payment service had to enhance continuously for the competitive advantage over the other payment service. Observability and convenience are also noted as important.

This research analysed the Interaction which focus on service quality perception, customer satisfaction, re-use intention in the golf club. First of all, we review the existing literature on measurement of service quality and management. As a result of this review and survey of the employer in golf club, thirteen factors emerged as important to the service management of the golf club; Reservation and Access(RSNA), Golf Course and Convenience Facilities(GCNF), Personal Services(PSER) and After Services(ASER). The structural equation model was utilized for analyzing the influence of service quality factors upon the customer satisfaction and re-use intention. Results show that service quality factors have a statistically significant impact on the customer satisfaction of the golf club. RSNA and GCNF investigated the factors influencing on the satisfaction degree of the customers. But the GCNF and PSER were not significant. Especially, GCNF factors directly influenced on the customer satisfaction and also indirectly impact on the intention of using again.

The objective of this study is to find the factors influencing the use of mobile service. We extracted critical study variables according to literature reviews about adoption of information systems, those under the internet environment and mobile internet adoption for theoretical foundation. TAM suggested by Davis(1985) has explained the acceptance mechanism with the following constructs: perceived usefulness, perceived ease of use, attitude toward use, behavioral intention and actual usage. After studying prior literature reviews, this study investigated the group of people using mobile services. The result of study claims that it has same results with previous TAM, especially between personal innovativeness and attitude toward use have strong statistical relations. On the other hand, there haven't been any statistical relations between perceived ease of use and perceived usefulness and between perceived usefulness and behavioral intention, either. In conclusion, use of mobile service can be promoted by developing various kinds of mobile service, designing device and interface to use mobile service more convenience and familiar, stimulating user's innovative characters and recognizing mobile service more useful in real life.

Most of the methods presented in the literature to define the target service stresses (Objective Service Stage, OSS) of cable-stayed bridges rarely include the time-dependent phenomena effects. Nevertheless, especially in concrete structures, this assumption might be on the unsafe side because time-dependent phenomena usually modify service stresses. To fill this gap, this paper studies the time-dependent phenomena effects into service stresses of concrete cable-stayed bridges. After illustrating the important role of these phenomena in an asymmetrical cable-stayed bridge without backstay, a new method to include their effects into the OSS is presented. An important issue to be considered in this method is the target time in which the OSS is defined to be achieved. The application of this method to two different structures showed the convenience of defining the OSS to be achieved at early times because that way the envelope of service stresses is reduced.

This study attempted to identify the service satisfaction with the 119 emergency service and the factors that affect it based on the responses of subjects who used the service. Data collection was conducted from February 11 to March 11, 2021, using convenience sampling. A total of 1842 subjects who used emergency medical services using 119 ambulance in 2020 participated. For the collected data, frequency, percentage, mean, and standard deviation were calculated, and t-test, analysis of variance, and multiple regression analysis were performed using SPSS 23.0. Based on these results, to further enhance the satisfaction of users of the 119 emergency service and the quality of emergency medical services, it is important to improve the quality of paramedics through education and systems. In addition, to increase user satisfaction, efficient and systematic communication education is required. The quality of emergency medical services will increase only when communication skills required for explanations and promoting understanding are improved.
