This Paper deals with the model of fixed-mobile interconnection. Specifically, how interconnection charge and originating price are determined when there is customer ignorance about terminating network or the price. This paper shows that the terminating charge with customer ignorance is higher than without that, and therefore the retail price becomes higher. This paper discusses the several methods to prevent the increase of the retail price and suggests the scheme to regulate the retail price and interconnection charge, simultaneously.

This study is designed to provide a facilitation program of the railroad tourist business that the bicycle is connected with the railroad. The sustainable growth will be achieved thorough the green growth being able to coexist with environment. To deal with the transportation problems -the environmental pollution caused by a large number of cars and the energy depletion, the traffic congestion- in our society is the prerequisites for the green growth. There is the need focusing on the expansion of the green network and the policy implementation of utilizing the bicycle, the formulation of the social consensus for environmental preservation. This provides the opportunity that we create the customer values and reinforce the firm's competitiveness. This study is to propose the plan for accelerating the tourism business connected to the bicycle, and to contribute to the government policy, to boost the green image of the railroad.

The information and communications service is recently being broadened, having much faster transmitting speed and multimedia performance. In addition, its introduction to general residential sites and construction of network facilities are being activated. Therefore new setup paradigm is being established other than the environment of plain old telephone service and data communication. In the present paper, the status of international and domestic standardization are reviewed and the operational environment of customer premise telecommunication facilities are investigated and analyzed. In order to enhance customer cabling facilities in Korea. The problems with the operational environment are analyzed, and how to improve customer cabling telecommunication facilities is suggested based on the above.

As the rate of personnel expenses of contact center operating costs is the highest, we can reduce operating costs, if we answer a automatic phone call wholly or partially. The MCS(Managed Contact Services) play an important role in cost reduction and work efficiency related with voice self-services. The excellent functions of the MCS are able to implement self-service applications in network connected with effective network routing of the enterprise. The MCS makes a proper consultant rapidly response and process customer calls, improve customer processing services, and consequently increase customer satisfaction. The increase of customer satisfaction lead to improve profits and reduce the cost of building contact center infrastructure. In this paper, we analyze the contact center line capacity and PBX capacity based on the MCS. We can reduce communication costs and personnel expenses by reducing the call shifting need between consultants and rapidly solving customer questions with the MCS.

A electronic business user is increased rapidly, and load of a electronic business system and network traffic are increased rapidly. Also, the data which included an audio and video is increasing in a electronic business system gradually, and According to this an Internet service businessman is paying for an enormous cost for management of a system and a maintenance of a line. It is brought a delay of a response speed about a service wish of a Web customer this system load and network traffic raise. Also, this decreases customer satisfaction and becomes an important factor to decrease competitive power of an e-business enterprise. In this study, we proposed the electronic business system that improved answer delay time about a Web customer in an e-business system based on the .net which was a the latest version of Microsoft company, and analyzed performance of a proposal system through an experiment. In the experiment result, the system that proposed it can have response time to have been improved and fast adaptability about various requests of a Web customer. Also, in a proposed system, a decrease gets a delay of a response speed to occur because of the multiple user done.

Purpose: Our purpose in this study is to compare the SERVQUAL, SERVPERF, and non-difference score measures and to find out which one is better for measuring the service quality of the multiplex cinema service. We also aim to analyze the structural relationships between service quality, customer satisfaction and customer loyalty. Methodology: For the study, we collected data from respondents who have used the multiplex cinema services and conducted an empirical test. SPSS 18.0 was used for descriptive frequency analysis, reliability analysis, and multiple regression analysis, AMOS 18.0 was used for structural equation modeling analysis of causal relationships among variables introduced in research hypotheses. Results: The main results of this study are as follows. First, we found that the non-difference score measure provided a much better model than did other service-measuring models (SERVQUAL, SERVPERF) in Korean and Chinese multiplex cinema. Second, two service-quality factors (Korea-tangibles and assurance vs. China-tangibles and empathy) between the multiplex cinema service quality factors significantly influenced customer satisfaction, which had a significant effect on customer loyalty in Korean and Chinese multiplex cinema. Conclusions: Based on the results, the authors discuss the implications and limitations of this study and future research directions at the end of the paper.
