As an extension of Technology Acceptance Models (TAM), the relative importance of perceived usefulness (PU) and perceived ease of use (PEU) in adopting two different mobile services are examined using service compatibility and user trust as moderating variables. This research shows that PEU is a relatively more important factor in the adoption of new mobile services when the new mobile services are highly compatible with existing services, while trust is an important influential factor in the adoption of services with a relatively low service compatibility. Trust does not significantly change the relative importance of PEU in the adoption of highly compatible mobile services, while the user's trust changes the importance of PU in the adoption process for the mobile services with relatively low service compatibility.

A single line diagram is a graphic user interface to represent electrical connectivity between power equipments in distribution automation systems. This paper proposes a new single line auto-drawing technique based on the service oriented architecture. Web service, CIM(Common Information Model) and SVG(Scalable Vector Graphics) are adopted to implement SOA concept. A web service demo system was established which is configured with the service provider, consumer and broker to verify the feasibility of this study.

This research focused on the comparison of corporate business mokels to explain different financial performances on the eBusiness domain. Especially, because customers have the more buying [ower tha other business areas, customer value and the service quality were prepared for independent variables and operational margin which can be obtained by publicize report was used for a dependent variable in stead of the other variables dependent on human perception as well. As a result, this research found that the customer value measured by service quality concept impact on the financial performance of eBusiness corporation positively. To find out more delicate results, structural equation was used for statistical method using 324 survey samples on 10 corporations. Though data using for statistical analysis were divided into individual and corporate level and have the time gap between research time and financial performance publicized period, the value of this research is that the customer value and service quality concepts with very objective financial information were input for constructing a research model.

Recent web environment needs a web service method that can integrate the individual web service. The UDDI registry can accommodate this need by classifying the information of the web service system for an easy retrieval of the information, thus it reduces the time to find a specific web service. Using the basic information search function of the UDDI registry, the web provider can offer various types of information to the client. In this paper, we implemented the process of registering the information to the UDDI registry and retrieving the various types of information from the UDDI registry in a given format.

Recently, RFID has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due to its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles: companies have their own operating systems, while RFID is developed regardless of each company's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system. Middle assures that companies adopting RFID system for their logistic service are given adaptability to any systems whatsoever, available by way of defining logistic information, tag information and reader information. For this purpose, we implement as the basic web service a middleware system that turns all data into XML(eXtensible Markup Language) of SOAP (Simple Object Access Protocol), the standard data.

The World Wide Web (WWW) has continued to grow at very rapid speed in both the sheer volume of traffic and size and the complexity of Web sites. Web Analytics Industry also has been growing rapidly. Web Analytics is to analyze web log files to discover accessing patterns of web pages. In this paper, we identify factors which can affect the continuous usage intention of a firm using services in web analytics services and empirically validate the relationships between the identified factors. For this purpose, we analyze 174 Korea firms. The analysis results show that the satisfaction is significantly associated with service quality and switching cost and the service usage period is not significantly associated with continuous service usage intention. We measure the service quality using SERVQUAL. It turn out that two dimensions of SERVQUAL, reliability and empathy are significantly associated with satisfaction, but another dimension of SERVQUAL, responsibility, is not. Finally, satisfaction is significantly associated with continuous service usage intention.

Recently the development of information technology and the emergence of electronic commerce have changed the model of purchase behavior in customers. This research aims to enhance the reliability of the result compared to the existing studies in internet shopping mall, and to find out the influence that logistics service quality elements has on customer satisfaction and that customers satisfaction has on the repurchase intention and word of mouth intention. To do so, prior researchs on the logistics service quality, customer satisfaction, repurchase intention and word of mouth intention was widely reviewed and the relationship between logistics service quality elements and customer satisfaction, and between customer satisfaction and repurchase intention and word of mouth intention were empirically tested. A total of 256 responses were received and analyzed from internet shopping mall. The analyses showed partial support for the affirmative effect of logistics service quality, customer satisfaction and post-purchasing behaviors in the internet shopping mall.

Purpose The purpose of this study is to verify impacts of factors, representing Push-Pull-Mooring(PPM) on switch intention to OTT(Over-The-Top) service in demand for content and to find relationship between factors through empirical analysis. Design/methodology/approach This study designed a research model by deriving factors affecting the intention to switch on OTT service based on the Push-Pull-Mooring framework and researches on OTT service. To test the hypothesis, a total of 357 responses were collected from individuals with experience in using OTT service and analyzed using SPSS26 and SmartPLS3.0. Findings According to the empirical analysis result, this study confirmed that the push, pull, and mooring factors proposed in this study had a significant effect on switching intention on OTT service. In addition, this study confirmed that both low switching cost and need for variety had a significant effect except for hypothesis H8.
