In 2013, the small retailer organized support service, which commenced in 2009, has been expanding its place in the policy by transforming into a small retailer cooperating support service. This support service supports two main sides. One of them is strengthening the financial aspects of the scale by organizing the small retailers in order to make the distribution efficient. The second is improving the management and enhancing the efficiency through visitation education. This research focuses on studying the effects of the visitation education which is one of the two aspects of small retailers support service. Empirical analysis on the effects of the visitation education's quality on the loyalty of support service and business performance was performed in detail by dividing the structure of the companies into chain form and combined form of small retailers. According to the results of the analysis, the visitation education's quality positively affected the support service's loyalty without any restrictions on the structures of the retailers. However in the business performances, the visitation education's quality only showed positive effects on the combined form of small retailers. Therefore, it is implied that in order to continuously receive support program by increasing the loyalty of the retailers, the quality of the visitation education must be increased and the retailer support service need to be considering the structure of the companies in order to improve small retailer's business performance.

A successful deployment of multimedia applications over wireless environments entails improving the quality of service (QoS), not only from a technical point of view, but also considering the quality of experience (QoE) from the final user's perception. Although objective QoE measure models avoid the difficulties of subjective surveys, subjective QoE assessments are essential to understand the way users evaluate the QoS. In this work, we study the effect of a wide range of parameters on the QoE of VVoIP applications in a real wireless scenario. Through a complete statistical analysis of users' ratings, we identify the following facts. Although the use of VVoIP in wireless networks does not yet represent an advantage for users, there are great expectations for all applications under study, and with greater popularity comes higher expectations. It is easier for respondents to identify good behavior than poor behavior. Whereas the respondents' frequency of Internet use does not impact on the scores, respondents' gender does. Finally, the most determining parameters of quality from a user's perspective were instability, video quality, voice distortion, usefulness, and graphical interface.

A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. These systems may then interact with the Web service in a manner prescribed by its definition, using XML based such as SOAP, WSDL, UDDI messages conveyed by Internet protocols. Especially, UDDI is the Web Services Registry enabling to register and search Web Services, that takes charge of providing infrastructure for Web Services. However, the existing UDDI has a few problems that searching process is very simple and it cannot provide information of Web Services quality and quality-based retrieval. Therefore, this study suggest the Web Services quality description model that evaluates the Web Services quality.

Application service provider(ASP) model is emerging as a new form of application outsourcing. ASP model may be attractive for small companies and even some medium-sized companies because these companies lack appropriate resources and technical expertise to develop and operate their information system. However, studies of ASP model have so far been neglected. Service quality is argued to be a crucial success factor for ASP, but yet there is not an empirically validated instrument for measuring ASP service quality. Therefore, this paper aims to develop and test a model for measuring ASP service quality. In order to accomplish these, SERVQUAL that has developed in marketing area were adapted to the context of this study. The research sample was designed by randomly selecting 300 different companies from the database that listed up the small companies participating in "ASP based e-business project for small enterprises". 240 usable responses were received by interview. The results are that reliability and tangibility impact user performances and satisfaction more than any of the service quality dimensions.

As the competition of 21 cyber universities in Korea has been on a continual increase, they are focusing on improving the quality of the e-learning education in cyber universities. In this study, we intended to derive the failure factors of the previous chatting system in the 2010s and the success factors from previous studies. Next, we identified priorities among five factors(Reliability, UI Convenience, Usability, Network effect, Operational policy) using AHP and the practical ways to implement the chatting service. We applied the chatting system to all the curriculums of S cyber university. Our study finds that the chat service affects the satisfaction of education. Finally, we propose the utilization plan to improve the e-learning education of cyber university through the findings of this research.

In B2B e-Commerce(Business to Business Electronic Commerce) market, many companies use B2B e-Commerce Guarantee Service. Guarantee service raised the stability of collect debts for seller, and made purchase fund for buyer. The purpose of this study is development of KPI (Key Performance Index) for measuring performance and improving service quality. Through analysis for 'B2B e-Commerce Guarantee Intermediary Service based on RFID', the study developed KPI and made the case. The study suggests KPI of B2B e-Commerce Guarantee Intermediary Service based on RFID by IT BSC(Balanced Scorecard) model. The process of developing KPI is 4 phase. First phase is connection between service goal and KPI, second phase is make a KPI pool, third phase is development of standard for valuating and selecting index, the last phase is defining and applying of index. This study suggests the standard of measuring performance in B2B e-commerce Guarantee Service and guidelines on revitalization of service in B2B e-commerce industry and the other industry.

Recently, the requirement of processing High Definition (HD) video or 3D application on low, mobile devices has been expanded and content data has been increased as well. It is becoming a major issue in Cloud computing where a Virtual Desktop Infrastructure (VDI) Service needs efficient data processing ability to provide Quality of Experience (QoE) in Cloud computing. In this paper, we propose three kind of Thick-Thin VDI Service which can share and delegate VDI service based on Thick Client using CPU and GPU. Furthermore, we propose and discuss the VDI Service Optimization Method in mixed CPU and GPU Heterogeneous Environment using CPU Parallel Processing OpenMP and GPU Parallel Processing CUDA.
