The Sido.Saeol system, a local government information system cost too much for having been designed and developed during last four years but the effectiveness of this system is still open to doubt. Also maintenance cost is still too high and become increasing year by year. To find out the reasons and to suggest how to solve these problems, a service quality of an Sido Saeol system and the public servant's job satisfaction were investigated based on the Delone and McLean's updated IS success Model(2003). To investigate of the effectiveness of the Sido Saeol system, 8 variables are analyzed to test 3 main hypothesis. After all the analysis, we found that Sido.Saeol systems have many aspects to be improved for system use and job satisfaction and have to be revise in the aspects of system qualities.

A rapidly increasing demand of voice and data through mobile telecommunication service and the development of technologies related with the service are sufficiently said to make the service become an indispensible communicating means, not just selective one. However, in the other side of the generalizing of mobile telecommunication service, there is said to be a worsening situation of unbalanced benefits due to the problem of information difference between the non. The more advanced mobile telecommunication service proceeds, the more deepens the problem, and it is generally known that the problem cannot be solved by the ability of free market itself as seen in the wired telecommunication market. Therefore, we need to set up a systematic policy of mobile telecommunication service for solving this problem, and also think over whether to include the service within the range of universal service. In this study, we examine the required factors for including the service within the range of universal service, and analyze the validity of the including in the view point of institutional aspects.

The quality of service on urban roadways have been evaluated mainly based on such quantitative measures as travel speed and delay. However, in addition to the quantitative aspects, drivers traveling on urban roadways are subject to be influenced by qualitative measures such as aesthetic aspects of the roadway and other drivers' violation of traffic laws. Based on this notion, this study attempts to identify roadway service quality indices, considering both qualitative and quantitative aspects and evaluate the quality of service using the modified Importance-Performance Analysis (IPA), a technique often applied in the field of marketing. The modified IPA is proposed in this study as a way to evaluate the service quality, reflecting the relative performance between study areas and performance indices. A case study is implemented over the Gangnam and Gangbuk areas in Seoul, resulting in identifying the items needed to be improved for each study area.

Purpose: In the context of the emergence of industry 4.0, using mobile phones as a modern distribution channel to execute financial services is a significant solution for commercial banks' retail services and a gateway to promote financial inclusion and market development. Despite that service quality and customer satisfaction are two diverse notions and closely related to each other in the service sector, there is hardly a research which empirically examines the impacts of each dimensions of mobile banking service quality and customer satisfaction. Research design, data and methodology: This study first employs in-depth interview to explore various aspects of mobile banking service quality dimensions, including empathy, responsiveness, tangibility, assurance, and reliability that serves to develop measurement scales and hypothesis development. A quantitative survey is followed to collect data from 265 Vietnamese bank customers to empirically test the conceptual model. Resutls: Our findings indicate that more human-related factors including empathy, assurance, and responsiveness show the strongest impacts on customer satisfaction with mobile banking service while tangibility and reliability, as technical aspects, are less influential factors. Conclusions: Finally, some crucial implications are drawn for the banks to manage consumer behavior in mobile banking.
