MVNO(Mobile Virtual Network Operator) promotes service competition in mobile telecommunication market and provides various service and opportunities for consumers. This study attempts to identify MVNO Service users' motivational and dissatisfying factors in relation to their willingness for continued use of the service 새 activate MVNO service. Use motivation factors are found as customer service, user interface, easiness, economical efficiency, and dissatisfying factors are handset quality, customer service, social influence. Economic efficiency factor had an affirmative influence on the sustained use motivation of the service users. Among dissatisfying factors, users had a negative influence when they recognize that their neighboring people does not use MVNO service. Policy authorities concerned must excavate a new plan to improve distribution structure of handset and reduce wholesaling cost of the MVNO service. It is necessary for MVNO service provider to develop a new business model so that users can recognize MVNO service not as inferior service but as rational and attractive service.

This study develops a model which measures service standardizations focused on the process of call center service. It analyzes the relationship between service standardizations and efficiency of business as well. The model consists of two dimensions to offering service and managing customers. These two dimensions have six major elements: accessibility, customer orientation, professionalism, offering a solution, customer satisfaction management, and customer information management. Also we assumed that low customer interaction and labor-intensive of service business increase the level of service standardization.

Objectives : This study examined relations between investment efficiency and management performance as indexes related to productivity of Korean regional public hospitals. Methods : The analysis data are financial information of Korean regional public hospitals from 2011 to 2014. For the indicators, value added to total assets, value added to productive activity tangible fixed assets, and value added to personnel expenses, operating margin to revenues, net profit to total earnings, and ratio of value added. Results : Significant relevance was not shown among indicators of investment efficiency. However, Significant relevance was shown between value added to personnel expense and productivity per value added. Conclusions : It confirmed that outside support funds like subsidy did not have effect on improving the management performance. Also, it could be known that availability about input of capital and labor was not realized organically.

The university organization is getting more and more complicated both in function and size these days, and the particularity of university organization inherently has quite a few element of internal conflict. To cope with the rapidly changing university society, together with the all-out effort of university CEO, it is necessary to pay attention to the administrative employees who can really contribute to the organizational competitiveness a lot. The Service Quality Management provides the action guidelines to every individual members of organization and alternatives to the problems the organization is facing. According only Service Quality Management can improve the efficiency of the organizational management and the job efficiency of individual members. Thus, in actual proof researching, we conduct and analyze how the university industries do Service Quality Management such as 6 sigma through survey researching.

This paper proposes a method for improving efficiency of high-voltage motors off-line insulation diagnostic test. The conventional manual test method has measurement errors and excessive processing time. We developed the KITAS system and solved these problems by using the instrument remote control and communication technology. The result of proficiency testing by interlaboratory comparisons using Power Factor Tip-Up test was '${\mid}E_n{\mid}$ < 1'. It was possible to confirm the validity of acquired data from the KITAS and establish a remote diagnostic system for easy access without physical limitations.

The object of this study was to investigate the effect of food material supply system on productivity in institutional foodservice. This study was examined by food service companies were enlisted under the influence of domestic enterprises, which used central supply system for the central kitchen operation and efficiency food material circulation system. The main result of this study was as follow: According to the analysis of these data, enlargement of efficiency in food utilization was placed at rising of utilization Processing food materials. And resulted in good expectations such as competitive strengthening, quality capacity strengthening and improvement in sanitary conditions from a productivity point of view.

Knowledge-based Service Industry is an industry that creates added value through the production, processing, and use of knowledge. Comparing to other service industries, it is innovation-oriented business endeavors having the characteristics that exert the great influences on other fields. Meanwhile, however, research efforts thereof are yet insignificant. In this study, we analyzed the innovation performance of architectural design office which creates knowledge services, having raised the necessity of innovation of the design office. The innovation performance were classified according to the extent of efficiency of the architectural design office making use of DEA-Tier analysis, and, for those architectural design offices that showed significant differences in efficiency, we presented the case studies of the firms that were substantial benchmarking targets from short, medium, and long-term perspectives.

We assess service delivery system for outpatients of general hospital(A) using service blueprint. Service blueprint for outpatients' service process currently being implemented in general hospital(A) is analysed to improve hospital services and define hospital service delivery system more accurately. In addition, comparative analysis of service blueprint between before and after improvement is conducted to find that health care services Is now more customer-oriented and hospital employees can link their duties to service delivery system. Dealing with the efficiency of health care service delivery system based on service blueprint analysis is expected to pave the way for continual service quality improvement of general hospitals in the future. The analysis of service blueprint of outpatients' service process suggested in this study is useful for setting strategies for health care service. It also helps service process design and service digitalization of other general hospitals in the future.

Arguments in favor of cyclic servicing, as opposed to random servicing, in connection with machines which stop in a random manner, are not conclusive because hitherto no general formular has been available for calculating the results which may be expected from cyclic servicing. The aim of the following paper is to help in evaluating the cyclic procedure by presenting a formular for calculating the standard efficiency of a group of semi-automatic machines assigned to one operator who will service them on a cyclic pattern.

The growing usage of multimedia communication applications with specific bandwidth and real-time delivery requirements has created the needs for quality of service(QoS). In response to the growing demand for an integrated services, the Reservation Protocol(RSVP) has been designed to exchange resource reservation among routers in the internet. RSVP protocol provides the quality of service for real-time applications but the network efficiency is reduced because of the limited bandwidth. In order to use network resources efficiently. We compare the resource efficiency of traditional reservation methods with that of the proposed method and evaluate the performance of the internet phone.
