The lowest price guarantee policy or price-matching guarantee is the pricing policy that promises to compensate more than the price difference if a consumer finds a lower price for the identical model he or she purchased and submits a certain proof. Most of Korean large discount stores emphasize their competitive price level by adopting the lowest price guarantee policy so that the entire Korean distribution industry is deeply influenced by the policy. The article is the study regarding the effects of the lowest price guarantee policy in Korean unique industry environments. The study investigated the effects of the policy on consumers' preferences of stores. By using the conjoint measurement model, it identified the main effects and interaction effects between the policy and other independent variables. The results showed the significant effects of the policy on consumers' preference of stores and identified the interaction effects between the distance from the residence and the policy, and between overall store price level and the policy.

Signal performances according link span dispersion compensation conditions at the 2000 km long-haul transmission distance using 10 Gbps 40 wavelength division multiplexing channels were analyzed and compared. 95%, 97.5%, 100%, 102.5% and 105% compensation conditions were applied and 97.5% gave the best performance without post dispersion compensation. the effects of accumulated dispersion value and average dispersion value per transmission link for each link compensation condition were analyzed. When post dispersion compensation optimization was applied to five link span dispersion compensation conditions, 102.5% was given the best performance.

Recently, many researches have been focused on multi-view video applications and services such as wireless video surveillance networks, wireless video sensor networks and wireless mobile video. In multi-view video signal processing, to exploit the strong correlation between images acquired by different cameras plays great role in developing a core technique of multi-view video coding. This paper proposes an adaptive multi-view video interpolation technique which is applicable for multi-view distributed video coding without requiring any cooperation amongst the cameras. The proposed algorithm estimates the non-linear moving blocks and employs disparity compensated view prediction, and then fills in the unreliable blocks. Through computer simulations, it is shown that the proposed method outperforms the conventional methods.

This paper presents a decoding technique for speech recognition using uncertainty information from feature compensation method to improve the speech recognition performance in the low SNR condition. Traditional feature compensation algorithms have difficulty in estimating clean feature parameters in adverse environment. Those algorithms focus on the point estimation of desired features. The point estimation of feature compensation method degrades speech recognition performance when incorrectly estimated features enter into the decoder of speech recognition. In this paper, we apply the uncertainty information from well-known feature compensation method, such as IMM, to the recognition engine. Applied technique shows better performance in the Aurora-2 DB.

As the business competition between firms is getting intense, one of the sources of competitive advantage is effectively and efficiently to create, share, and apply information/knowledge among employees. Most of the firms which conduct knowledge management are operating a Community of Practice(CoP) in order to create, share and utilize this kind of information/knowledge resource. Recently, the CoP is getting out of its informal and spontaneous manner and is beginning to be led by the top management, receiving official support, in order to achieve the organization's strategic goals. However, the corporation's strategic operation of the CoP is not only against its original characteristics but also hampers the spontaneity of its participants. Every participant has different motivation to participate and different preference for reward type. This study, with the survey of 114 respondents, found that intrinsic motivation as well as extrinsic motivation significantly affect the motivation-reward fitness. Also, the motivation-reward fit was found to influence CoP commitment which ultimately leads to knowledge sharing activity in the CoP context. This research will help knowledge management companies to figure out how the two things of participants' motivation and their reward types can fit together, and how such fitness ultimately affects the participants' commitment and their knowledge sharing activities.

본 논문에서는 비선형 상호 결합 시스템의 출력 궤환 제어기 설계에 대해서 연구한다. 먼저 퍼지 모델 기법을 이용하여 비선형 상호 연결된 시스템을 Takagi-Sugeno (T-S) 퍼지 모델로 모델링한다. 그 각각의 하위 시스템에 대한 출력 궤한 제어기를 동적 병렬 분산 보상 (DPDC) 기법을 이용하여 퍼지 출력 궤환 제어기로 설계한다. 하위 시스템들의 평형점이 안정화 되는 선형 행렬 부등식 (LMI)를 구하고, 그 부등식을 만족하는 값들로부터 하위 시스템의 제어기 이득을 구한다.

The purpose of this study is to find out how the online brand community characteristics affect customer behavior according to self-construal level and gender difference. The characteristics of online community are divided into interaction, objectivity, information provision, and activity reward. First, interactivity and activity compensation among the characteristics of online community have a positive effect on brand community commitment. On the other hand, the effect of purpose and information provision is insufficient. Second, the greater the commitment to the brand community, the higher the WOM effect is. Finally, this study shows that customers with dependent self-construal tendencies have more brand community support than customers with independent self-construal tendencies, and females show more brand community support than males. This study suggests an efficient marketing approach to companies through a brand community commitment by understanding the intrinsic motivation of consumers' self-construal level.

The purpose of this research is to suggest a guideline for direction of content design and resource allocation to make mobile social network game (mobile SNG) production more efficient. We assumed that commercial purpose of mobile SNG is to improve uses' intention of use of the game, and from previous researches we selected flow, social interaction, self efficacy, competition, and reward as the factors which have influence on the intention of use. Finally, improvement of user experiences related to social interaction, self efficacy, competition, and reward is considered as the purpose of the mobile SNG contents. We surveyed university students in Gangwon, South Korea who have used mobile SNG. It took 3 weeks and 244 survey papers were used for analysis. The method for analysis was hierarchial regression analysis using SPSS 18.0. As a result, we found that the user experiences related to self efficacy, reward, competition, social interaction provided by SNG contents are all have positive influence on the user's intention of use and weighed the influence of each factors.

고객이 서비스상의 실패에 대해 때로는 강한 부정적 반응을 보이기에 서비스를 제공하는 조직의 서비스회복능력은 고객만족을 달성하기 위해 강력하고 효율적으로 운영되어야 한다. 따라서 본 연구는 온라인상의 서비스인 ISP업체(10개의 회사)를 대상으로 온라인 서비스 상에서 고객이 서비스상의 불만을 경험할 때 기업이 고객의 불만을 회복시켜 만족으로 전환시키려는 회복속성들이 실제로 고객이 가지는 분배상의 공정성, 절차상의 공정성 및 상호작용 공정성에 어떤 영향을 미치는가를 실증적으로 검증하기 위한 것이다. 이를 위해 10개의 ISP업체를 선정하고 해당 업체에 대해 불만을 가진 고객들이 기업의 불만제거 노력에 대해 평가하도록 하였다. 가설 검증을 위해 LISREL을 이용하여 서비스의 회복속성인 보상, 신속한 반응, 무반응, 사과, 사전보상제공 등이 분배상공정성, 절차상 공정성, 상호작용 공정성에 직접적으로 미치는 효과를 파악하고 이 공정성의 요인들이 만족에 미치는 영향도 실증적으로 검증하였다. 온라인 상이라는 새로운 환경을 고려하여 기존의 모델에서 간과된 부분을 확인하기 위해 확장 모델을 제시하여 새로운 의미를 가진 경로가 존재하는지 확인하고 이 부분에서 유의적인지 않은 경로를 배제한 수정모델을 제시하였다. 기존의 연구를 바탕으로 제시된 가설은 연구모델에서 경로 계수를 추정하고 이에 대한 t값을 통해 검증하였다. 본 연구에서 제시하는 시사점으로는 고객의 서비스 실패 및 회복상황에 대한 평가의 이론적 원칙을 설명하고 관리자에게 각각의 서비스 실패와 일치하는 서비스 회복전략을 제시하여 운영상의 가이드 라인을 제시한다고 할 수 있다
