성숙기에 접어든 국내 렌터카 시장에서 AJ렌터카는 정체된 경쟁 상황을 타파하고 차별적 경쟁 우위를 확보하여 시장을 선도하기 위하여 2006년에 고객 만족 경영을 기업의 비전으로 선포하고 다양한 서비스 혁신 활동을 통한 고객 만족 경영을 전개해 나가고 있다. 그 결과 현재 서비스 품질 지수, 고객 불만율 등 주요 서비스 관련 지표가 눈에 띄게 호전되고 있으며 향상된 서비스 지표들은 고객 만족 지수와 재이용 의도 등의 고객 만족 지수들에도 직접적인 영향을 미쳐 이 부분에서 경쟁사들을 앞서 나가고 있다. 이런 고객 만족 경영의 성공은 짧은 기간에도 불구하고 기업의 신규 고객 유입 수의 증가와 매출액 증가 등 전반적인 경영 성과 지표에도 직접적으로 반영되고 있다. 본 사례연구에서는 이와 같은 성공의 원동력이 된 AJ렌터카의 서비스 경영 활동을 살펴보고 그 전략을 분석하여 보고자 한다. 보다 구체적으로, AJ렌터카의 서비스 경영 전략, 고객 관리 프로세스, 다양한 고객 만족 경영 활동의 예, 서비스 경영 활동의 성과, 그리고 핵심 성공 요인을 분석해 보고자 한다.

현재까지 오류 데이터를 정제하는 기법은 여러 소스로부터 대량의 데이터를 통합하여 데이터베이스에 저장되어 있는 데이터의 품질을 관리함으로써 의미 있는 정보를 추출하기 위함이었다. 급변하는 비즈니스 환경과 무한경쟁 사회에서 지속적으로 생존하려면 환경 변화에 빠르게 대처해야 한다. 최근 시스템의 요구사항이 복잡해짐에 따라 대규모의 분산 시스템을 통합 구축하기 위한 서비스 기반 구조 (Service Oriented Architecture)로 확산되고 있으며, 여기에서도 각 서비스간의 데이터 정제기법을 통한 신뢰성 있는 데이터 교환이 필수적이다. 따라서 본 논문에서는 서비스들이 하나의 시스템으로 통합되는 과정에서 이벤트를 통해 서비스 간에 전송되는 XML데이터의 품질 관리를 수행하여, 이미 통합되어 저장된 데이터베이스 데이터의 오류를 탐지하여 정제하는 것이 아니라 상호 작용하는 서비스간의 데이터 정제에 초점을 두고 SOA를 기반으로 하는 오류 데이터 정제 서비스를 개발한다.

The market competition of express package deliveries in Korea is severe because a large number of companies have entered into the market. This study thus suggests an approach to the reconfiguration of express service networks with respect to the strategy partnership of closing/keeping service centers among companies involved and the adjustments of their cutoff times. For this we propose an integer programming model and a genetic algorithm based solution procedure for allowing companies involved to maximize their incremental profit. An illustrative numerical example is presented to demonstrate the practicality and efficiency of the proposed model.

The advanced computer network technology enables connectivity of computers through an open network environment. There has been growing numbers of security threat to the networks. Therefore, it requires intrusion detection and prevention technologies. In this paper, we propose a network based intrusion detection model using Fuzzy Cognitive Maps(FCM) that can detect intrusion by the Denial of Service(DoS) attack detection method adopting the packet analyses. A DoS attack appears in the form of the Probe and Syn Flooding attack which is a typical example. The Sp flooding Preventer using Fuzzy cognitive maps(SPuF) model captures and analyzes the packet information to detect Syn flooding attack. Using the result of analysis of decision module, which utilized FCM, the decision module measures the degree of danger of the DoS and trains the response module to deal with attacks. The result of simulating the "KDD ′99 Competition Data Set" in the SPuF model shows that the Probe detection rates were over 97 percentages.

웹서비스의 경쟁이 심화됨에 따라 고객 개개인의 특성을 반영한 맞춤형 서비스의 지원 필요성이 증가되었으며, 이러한 개인화 서비스를 지원하는 고객화 시스템에 대한 연구가 활발히 이루어지고 있다. 대부분 고객화 지원 시스템은 각종 수집 가능한 고객의 개별적인 특성을 위주로 하는 정량적으로 표현되는 자료의 분석을 통해 이루어지고 있다. 하지만 감성 정보의 경우 정서적인 데이터 특성으로 인해 이를 웹 시스템에 활용하기에는 어려움이 있다. 따라서 웹 환경이라는 기술적인 상황에서도 활용 가능한 감성정보의 활용에 관한 연구가 필요하다. 본 연구는 고객의 감성지수를 이용한 적응적 고객화 서비스를 지원하는 웹 시스템을 설계하고 실험을 통해 분석하였다.

This paper analyzes the impact of the change in telecommunication regulation changes including the unification of telecommunication service on network investment. The unification of telecommunication service plays a role of separating behavior regulation from entrance regulation and reducing entrance constraints. Therefore, it is expected that the market spillover effect is high through the improvement of behavior regulation. In addition, the effects of the other regulation changes in the 2010 Telecommunications Business Act revision are analyzed. This paper discusses critical factors affecting the decision making process in respect to the firm level and analyzes the impact path guiding investment and innovation. The key findings are as follows. First, the impact of entrance deregulation depends on the intensity of deregulation. If the intensity is not high, this regulation increases the incentive on investment and innovation. However, if the intensity is high as shown in abolishing of licensing, it affects the incentive negatively. Second, if interconnection regulation focuses on existing facilities or the intensity is not strong, this light handed regulation might increase investment and innovation. However, if interconnection obligation is expanded to the facility not constructed or the facility applying new technology, this regulation might deteriorate investment. Third, price deregulation increases the competition of service but it also increases the business opportunity, which means positive effect on investment. Finally, the paper proposes the guideline for telecommunications policy.

With recent advances in media technology, the creation of a relatively new service, N-screen, has been realized. N-screen provides seamless connections among various media and enables users to enjoy entertainment content at any time and any location. With such recent advances comes opportunity; therefore, for those N-screen service providers who have established an early edge in the ICT industry, it is imperative that they maintain this and stay ahead of the ensuing competition. In this context, the objective of this study is two-fold; first, we aim to find factors influencing the behavior of existing and potential N-screen service users, and then second, to examine the differences in how these factors operate within the two user types. The results of this study show that the perceived value and subjective norm are important influencers in both user types. However, price fairness and innovativeness are only influential on the attitude and intention of potential users, while some aspects of media usage have only significant influences on the behavior and loyalty of existing users. Based on these results, we provide some implications for both researchers and practitioners who wish to better understand the nature of N-screen users.

In response to the government's recent attempts to introduce competition and efficiency criteria in the rural railway service provision, this study is to empirically estimate public service values on continuous operation of two rural railways-Young Dong Line (YDL) and Donghae Nambu Line (DNL)-that will be realized beyond the passengers' use values. Based on a contingent valuation survey conducted on 600 passengers and local residents, YDL respondents were willing to pay significantly higher amount compared to those of DNL respondents. Especially tourists traveling on YDL were willing to pay the highest amount, and local residents of DNL were willing to pay relatively high amount. The results will provide useful information in makings decisions on the selection of PSO railways, the amount of PSO compensation and which railways to close, so on.

Social media websites have continued to proliferate, and the way in which people stay connected has also evolved. The issue of user loyalty a website remains crucial given that the competition is severe. Websites need loyal users who continue to use their sites to survive and be successful. In this research, we applied self-regulation framework to investigate the factors leading to user loyalty to a social media site. In particular, the role of sense of belonging, which is a common emotional reaction to a social media site, is examined. A survey of users in a popular social media site in Taiwan was conducted. Results show that both sense of belonging and service quality have direct effect on loyalty, whereas trust affects loyalty indirectly by fostering a sense of belonging. Service quality affects loyalty through trust and sense of belonging. Notably, trust has insignificant effect on loyalty as originally proposed. Users are then classified into two groups, namely, heavy and light users, based on their usage. Among light users, service quality has no direct effect on loyalty. Therefore, sense of belonging has sole direct impact on loyalty. Both service quality and sense of belonging contribute to loyalty in users who spend more time online. Implications of this study are also discussed.
