현재 MPEG에서 무료(Royalty-Free) 비디오 코덱으로 표준화 중인 IVC(Internet Video Coding)에서는 인트라 부호화를 위하여 DC 모드의 한 가지 예측 모드만 사용하고 있다. 이러한 기존의 인트라 부호화 기법은 부호화 모드를 시그널링할 필요가 없고 부호화 시간이 빠른 장점이 있지만 인트라 예측의 정확도가 많이 떨어짐에 따라 부호화 효율이 저하된다. 본 논문에서는 IVC의 인트라 부호화 성능 향상을 위하여 4 가지 예측 모드를 지원한다. 즉, 공간적 상관성을 고려하여 평활화된 참조화소 값을 사용하는 평활화된 다중모드 인트라 부호화 기법을 제안한다. 실험결과 제안된 기법은 All-Intra 부호화 구조에서 기존의 ITM 6.0 대비 7.4% 정도의 비트율 감소를 얻음을 확인하였다.

This research demonstrates a 3D virtual visualization of urban environment and video fusion for effective damage prevention and surveillance system using open standard. We present the visualization and interaction simulation method to increase the situational awareness and optimize the realization of environmental monitoring through the CCTV video and 3D virtual environment. New camera prototype was designed based on the camera frustum view model to project recorded video prospectively onto the virtual 3D environment. The demonstration was developed by the X3D, which is royalty-free open standard and run-time architecture, and it offers abilities to represent, control and share 3D spatial information via the internet browsers.

We studied franchisees’ answers to the questionnaires to know their selective motives and criteria, their types and the reliability of a franchisor in the food-service industry. Then we showed the basic data about the selective criteria of a sound franchisor. The result of this study was as follows. First, we need a specialist and a department to present a financially sound franchisor. Second, we must determine the criteria of franchise fee, royalty and the other items on payment for the franchisor. Third, the alternative plan to trust the franchisor was needed for a large-scale franchisee.

현재 MPEG 에서 Royalty-Free 비디오 코덱인 Type-1 표준으로 진행중인 IVC(Internet Video Coding)에서는 저지연 모드(LD: Low-Delay) 부호화 구조에서 비참조 P 프레임 부호화 기법을 적응적으로 사용하여 부호화 이득을 얻고 있다. 비참조 P 프레임 기법은 P 프레임의 타입을 지정하여 고정된 부호화 구조의 비참조 P 프레임을 적용하고 있으나, ITM(IVC Test Model) 9.0 에 구현된 부호화 구조는 다중참조 프레임(MRF: Multiple Reference Frame)을 사용할 때 시간적 예측 거리가 먼 참조 프레임을 먼저 예측하는 단점이 있다. 본 논문에서는 다중참조 프레임에서 기존의 P 프레임 타입 설정을 변경하여 비참조 P 프레임의 부호화 구조를 개선하였다. 실험결과 제안 기법은 시퀀스에 따른 큰 성능 저하 없이 기존 기법 대비 0.6% 정도의 추가적인 비트율 감소로 얻음으로써 비참조 P 프레임 기법이 ITM 9.0 대비 7.9% 정도의 비트율 감소를 얻음을 확인하였다.

With the rapid development of digital technology, the satellite DMB service is able to provide chance to watch on TV, movie and listen on the Radio to their subscriber with moving. From the mid 2005, Korean people can get the satellite DMB service which includes In many kinds of new telecommunication services such as watching on tv, movie, and listening the music on service charge. The objective of this study is to grasp the factors which affecting the use satellite DMB service on the consumers who pay service charge, and to make an analysis on the structure relationship between such factors with consumer satisfaction and consumer royalty.

Purpose: The purpose of this study is to analyze the effect of attributes of online influencers on customers royalty mediated brand image and impulse buying. Research design, data and methodology: To conduct this study, a survey of 521 online user who experienced online shopping. Results: The empirical analysis results are as follows. First, among the influencer attributes, attractiveness, reliability, and expertise all had a significant positive effect on the brand image. Second, among the influencer attributes, only attractiveness had a significant positive influence on Purchase Intention. Third, the brand image had a significant positive influence on Purchase Intention. Fourth, while the influencer attributes did not have a significant influence on customer loyalty, brand image and Purchase Intention a significant positive influence on it. Conclusions: Among the influencer attributes, attractiveness and reliability had a significant positive mediating effect on customer loyalty through brand image, but the influencer attribute had no significant mediating effect through Purchase Intention. The influencer attribute had a significant positive mediating effect through brand image and Purchase Intention.

Companies are required to invest in numerous intial marketing costs for establishing brand power, thus, many companies in the foodservice industry are increasing their budgets on communication to strengthen their own brand equity components such as brand recognition, brand royalty, perceived quality and associated image using mass media that has not been used before. For this study, 617 samples were analyzed by such analytic methods as a frequency analysis, cross-tabulation, a factor analysis and a reliability analysis for validity, and a confirmatory factory analysis, a model adequacy evaluation, and a path analysis using AMOS 17.0. The hypothesis verification by the AMOS analysis has revealed that all hypotheses positively influenced contract foodservice brands, and the brand recognition of a university contract foodservice company has an impact on sincerity and refinement. Therefore, positive brand image formation encourages strong brand establishment between a university contract foodservice business and customers, and this study strongly suggests continuous further studies about constructing a positive brand image.

This study tries to identify the determinants of user's attitude toward apps, intention to use and continual consuming intention. This study holds the two main constructs: (1) user's intrinsic determinants- value, innovativeness, gender, Well-being and superordinate influence - on the attitude toward mobile apps, (2) the relation between attitude and app purchase & repurchase intention, and the affecting factors among this relation. In the empirical test result, value, innovation and superordinate influence were identified to affect the attitude. All the relation among attitude, purchase and repurchase intention showed positive significant relationship. In addition, satisfaction intensified the relation between purchase and repurchase intention.
