While many services appear, it are performed in the various researches about a service. Among them, as to the basic reason for measuring the service level, in order to find out the strategy improving service quality. But the method for measuring quality of services up to date was unable to make it enough the role. This research tried to propose the approach systematically analyzing the human errors in order to improve service quality about the call center which utilizes the information technology. In fact, the human errors was found in the customer contact point in which the actual service is delivered. An interaction between the element for comprising call service was classified into 3 while defining the human error as 3 group. Moreover, the process where a service is delivered was classified according to 5 step and the generated error was measured in each step. The implication of this research looks at the service failure and dissatisfaction as the occurrence of the human errors and illustrates the service quality improvement as a correction or a reduction. This approach is used that service is materially easily understood and is formulated with the quality improvement strategy.

Development, availability and users' participation in the information service of agricultural food sector is slower than that of other sectors in Korea. This phenomenon comes from the lack of development strategies and comparative analyses with other sectors, as well as the agricultural food industry's own characteristics which is developed based on the offline market. In this research, we will discuss about how to improve the public information service of agricultural food sector based on the example of establishing service improvement strategy by the most representative Okdab. In this research, we have drawn the following implications for development strategy of Okdab service based on three core keywords derived from benchmarking KOSIS. Three core subjects for upgrading public information service are 'analysis information with expertise and differentiation,' 'user cooperation-oriented platform,' and 'intuitive nd effective UX,' and to strength B.I. as an integrated information service of agricultural food sector, we need to identify the users' satisfaction and needs for the existing service, establish an optimized operating strategy on a short-term, mid-term and long term bases, and implement them in a positive way. Based on this positive action, it can become a trustworthy information service for the users, and we can expect the improvement of the users' recognition for its consistent usability and efficiency.

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.

The purpose of this study is about the influence of the Service quality on the customer loyalty depending on the customer value(social and psychological value, functional value) because of the dynamic business environment is react quickly and flexibly, many of today's companies are required to consult an expert. According to the circumstances, Service Firms(Hotel) should be provide a differentiated service for each customer. And this paper attempt to theoretical organize and take advantage of practical in Service industry. The questionaries of 154 from the companies which have received Service in 3 years in the metropolis and small and medium-sized cities were used to test hierarchical regression model with mediating effects of customer value between Service quality and Customer loyalty by SPSS(PASW) 18.0 version. From these analyses, the following results were obtained: First, social-psychological value have partially mediated effect on the tangibility, responsibility, assurance and customer loyalty. Second, functional value have partially mediated effects on the between tangibles, reliability and customer loyalty. The result suggests that 'tangibility', 'reliability', 'responsibility', 'assurance', 'empathy' are the most important factors to affect customer loyalty, and there are partially mediated effects of customer intention between Service quality and Customer loyalty. In conclusion, to improve the specific and actual meaning and value about the Hotel service quality and to give the suggestions on the Hotel's marketing communication by understanding the customer action.

This study, which took place in an Italian restaurant in Seoul, investigated the impact of meal duration on the evaluation of satisfaction and service quality, according to the service stages (order, cook, check) of a restaurant. Research procedures included two phases: during the first phase, data on expected-perceived meal duration, and service quality and satisfaction were collected by surveys, which were distributed at the restaurant. The second phase investigated the relationships among meal duration, customers' satisfaction, and service quality. T-tests and regression analyses were used to examine relationships between these variables. Results indicate that both failing to meet customers' expected meal duration, as well as the perceived meal duration could negatively impact the satisfaction and evaluation of service quality. The study confirmed that meal duration is indeed related to the responsiveness aspect of service quality. The important aspect of meal duration management is to improve service quality and satisfaction, which can lead to a restaurant's success. Therefore, understanding the relationships among meal duration, satisfaction, and service quality is a part of a good foundation for effective meal duration management.

This paper proposes an intrusion detection system for in-vehicle network to improve detection performance considering attack counts and attack types. In intrusion detection system, both FNR (False Negative Rate), where intrusion frame is misjudged as normal frame, and FPR (False Positive Rate), where normal frame is misjudged as intrusion frame, seriously affect vechicle safety. This paper proposes a novel intrusion detection algorithm to improve both FNR and FPR, where data frame previously detected as intrusion above certain attack counts is automatically detected as intrusion and the automatic intrusion detection method is adaptively applied according to attack types. From the simulation results, the propsoed method effectively improve both FNR and FPR in DoS(Denial of Service) attack and spoofing attack.

The realization of u-City is coming near in some local governments by applying various city services, namely, u-City services to the city construction field to improve competitiveness of the city. But it is a reality that some local governments are experiencing many trial and errors in application of the u-City service in addition to the problem posing that the u-City service is not considering characteristics of development or application environment of an individual city. The present research proposes a service model for on-site application of the u-City service to solve this problem. The proposed model suggests a method for specifically conceptualizing and objectifying the on-site application that the existing concept-oriented model or an architecture-oriented model, etc. didn't provide. The verification system on effectiveness or effects of the u-City service model to remove ambiguity on the u-City service especially. The verification system of the u-City service model grasps the technology, function, procedure and target, etc. that the u-City service contains, evaluates whether the model satisfies conditions that the model should have, and secures objectivity and predictability of the u-City service model through confirmation on propriety, implementation and effectiveness, etc.
