This study is to examine the effects of e-CRM activities(e-Sales activities, e-Service activities and e-System activities) and trust on loyalty. Particularly, it focuses on the mediating effects of trust on the relationships between e-CRM activities and loyalty. The data is collected from 336 university students over two and half month periods. The results are as follows: Firstly, e-Sales activities, e-Service activities and e-System activities effect exert a significant influence on the trust, but e-Sales activities, e-Service activities and e-System activities do not directly influence on the loyalty. Secondly, trust impacts significantly on loyalty. Finally, in summary, findings confirm the mediating effects of trust on the relationship between e-Sales activities, e-Service activities and e-System activities and loyalty. These results show that if e-commerce firms implement e-CRM activities(e-Sales activities, e-Service activities and e-System activities), their customers will more recognize additional service attributes and the customers' relationships, trust and loyalty with their firms will improve.

BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.

With rapid changes taking place in every field, the expansion and specialization of various social service activities are one of the characteristics of the modem society. However, the increase of crimes and inefficiency of public police service to cope with this situation have caused discontent and distrust on the service among the public, making people more inclined to solve safety-related problems by themselves. Private Security Service(PSS) and Private Investigation Service(PIS) were introduced to satisfy these needs. In the area of PIS, Public Investigation Service System(PISS) has been established for a quite long time in foreign countries. However in Korea, PIS is being provided by unregulated service providers such as errand service center due to the lack of legal system, causing many problems related with illegal practices by the service providers. This paper is the result of the research on how to adopt a relevant PISS in Korea and develop it in the future. This kind of research is much needed to curb the rising illegal practices of the errand service centers, complement the insufficient operation of public police service, and strengthen the competitiveness of our country by taking more efficient actions in the changing public security environment. Based on the research, this paper also examines positively the possibility of introduction of PIS in Korea. This paper also recommends a prompt enactment of PIS regulation and improvement on the legal environment for such introduction of the relevant and suitable PISS in Korea.

Free-viewpoint video (FVV) service provides multi viewpoints of contents and synthesizes intermediate video files which are not captured on some view angles so that enables users to watch as they choose wherever they want. Synthesizing video is necessary technique to provide FVV video service, because every video of the FVV contents for different view angles cannot be stored to the content server physically. For the reason, fast view synthesis can improve the quality of video service and increase user's satisfaction. One of the studies for FVV service, a method was proposed to transmit FVV service based on DASH (Dynamic Adaptive Streaming over HTTP). There is big advantage on using DASH that it is commonly used to transport video service. However, the method was only a conceptual proposal, so it is difficult to implement the system using the proposal. In this paper, we propose an implementation method to provide real-time FVV service smoothly. We suggest a system structure and operation method on the server and client side in detail, which is to be applicable to synthesize video quickly. Also, we suggest generating FVV service map additionally which controls a FVV service overall. We manage real-time information of the whole service through the service map. The service can be controlled by reducing the possible delay from network situation.

DMB video/audio service was successfully launched. DMB data service is a matter of primary concern now. The TTI(Traffic and Travel Information) service is considered as a killer application of the data service. Tn this paper, we propose a method for design and implementation of the broadcasting system for TTI service. The proposed TTI service system consists of an authoring tool, the DB module, the Transmission module and Monitoring module. This system satisfies the national TTA standards of the Traffic and Travel Information data services for terrestrial DMB; TPEG(Transport Protocol Experts Group) platform. The system was designed to support real-time automatic transmission for CTT and CTT SUM, and non real-time authoring & automatic transmission for POI and SDI, and was focused on the capability to make high-quality contents efficiently and to send them to the data inserter reliably. The performance of the implemented system was proven through the conformance tests with the various commercial receivers. After the continuous upgrade, the system is being used in commercial service.

We consider a generalized N-policy for an M/M/1 queueing system. The idle server starts to work with ordinary service rate when a customer arrives. If the number of customers in the system reaches N, the service rate gets faster and continues until the system becomes empty. Otherwise, the server finishes the busy period with ordinary service rate. We obtain the limiting distribution of the number of customers in the system. After assigning various operating costs to the system, we show that there exists a unique fast service rate minimizing the long-run average cost per unit time.
