전자 상거래에 대한 관심이 높아지면서 전자 상거래에서 제품과 서비스에 대한 구매를 결정하는데 중요한 역할을 하는 전자 카탈로그가 주목을 받고 있다. 원격 교육 분야의 SCORM은 좋은 품질의 학습용 콘텐츠를 적은 비용으로 재사용할 수 있는 장점을 지닌다. SCORM을 전자 카탈로그에 적용시킴으로써 제품 공급 업체가 제공하는 제품 정보와 제품과 관련된 여러 가지 정보를 쉽게 공유할 수 있고 재사용할 수 있다. 전자 카탈로그에 원격 교육 분야의 표준안인 SCORM을 적용시켜 새로운 콘텐츠 모델을 제안한다.

IPTV(Internet Protocol Television) is an innovation technology to lead the new media age. Internet protocol television (IPTV) is a next generation television converged with the Internet which are delivered portal services such as information search, games, movies, home shopping and banking. Generally, service quality affects to adopt or use these technologies. Quality of experience (QoE) is more issue to be considered than service quality because of the technological restriction and limitation that IPTV is accessed by the Internet. The QoE is defined as the cognitive and experienced quality measured with users through an experiment and is conceptually related to service quality. The objective of this paper is to suggest a methodology to measure the QoE of IPTV using a user testing. We find significant factors affecting QoE of IPTV through an exploratory study and measure QoE scores. We found the nine factors of graphics, picture, accuracy, access method, quality of contents, usability, security, and performance important for QoE. The QoE scores of picture, graphics, and quality of contents gained over the average score, but the overall score for IPTV service providers was not high and the QoE needs to be improved.

A currently domestic governmental R&D business is early to 100. And this is each managed individually in 15 professional organizations of research and management by characteristics of a business. For this Reason, A redundant investment issue regarding national R&D occurs, and an issue regarding efficiency of R&D investment by insufficiency of systematic R&D research project and result management is continuously raised. Ministry of Education Science and Technology establishing National Science & Technology Information Service(NTIS) in order to solve these issues. NTIS is the national R&D Portal System which can support efficiency of research and development to result utilization in planning of national research and development. In this paper We consider integrated DB constructions and Information Linking of R&D Participants/Projects/Results information in a NTIS system for data quality Improvement. and then We analyze the cause of the data quality problem, and we propose the improvement plan for data quality elevation of NTIS system.

This research was developing a mobile-based service system through which consumers can collect labeled information on processed foods. This research collected and analyzed the labeled information of processed foods sold on the market and found that they contain abstruse standards for the information of raw nutrients and additives and are not proper for our database. Thus, to offer proper consumer-oriented information, we reclassified the information according to categories such as raw materials, additives, and nutrient information based on the food information standard of the current Food Sanitation Act, and added it to the database. Using this reprocessed information, this study developed an algorithm and applied it to a mobile-based service system, which allows consumers to use information on the labels of processed foods scientifically and clearly.

Digital signage is referred to as a smart electronic display system that delivers multimedia-based information and advertisements to customers. Typically, the digital signage starts its playback after downloading a list of multimedia contents from network storage to its local disk. However, a way of downloading the entire contents before its playback entails a long initial delay time. In this paper, we formulate a problem of the initial delay time and provide a solution to compute a minimally demanded initial delay time according to a given network bandwidth and qualities/sizes of the multimedia contents. In addition, we analyze the performance of the proposed solution with various multimedia contents on digital signage.

The importance of knowledge and information is ever increasing. The ingredients of the customer value of the information offered for free by the public information organizations are different from those of the ordinary products or services. This study aims to identify the factors which affect the information customer value and the job performance of the R&D managers who use national R&D information service(NTIS). The results show the quality of information service and the perception of services organizations have significant positive effect on customer value. In addition, the customer value have significant influence on the job performance. Meanwhile, the perception of information organizations have not effect on the job performance. Regarding the moderating effect of the information using environment, the results are as follows: the information using environment moderates the relationship between the information service quality and between the customer value and the perception of information organizations, and the relationship between the customer value and the job performance, but does not moderate the relationship between the perception of information services organizations and the job performance. According to the research results, we proposed several implications to foster the customer value management in the field of public information as well as future research directions.

3D 콘텐츠를 획득하는 여러 가지 방법 중 2D-plus-Depth 구조는 다시점 영상을 얻을 수 있는 장점 때문에 최근 이에 관한 연구가 활발히 진행되고 있다. 이 구조를 통해서 고품질의 3D영상을 얻기 위해서는 무엇보다 고품질의 깊이 영상을 구현하는 것이 중요하다. 깊이 영상을 얻기 위해서 Time-of-Flight(ToF)방식의 깊이 센서가 활용되고 있는데 이 깊이 센서는 실시간으로 깊이 정보를 획득할 수 있지만 낮은 해상도와 노이즈가 발생한다는 단점이 있다. 따라서 깊이 영상의 특성을 보존하는 상환 변환을 하여야지만 고품질의 3D 콘텐츠를 제작할 수 있다. 주로 깊이 영상의 해상도를 높이기 위해서 Joint Bilateral Upsampling(JBU) 방식이 사용되고 있다. 하지만 이 방식은 4배 이상의 고 해상도 깊이 영상을 획득하는 데에는 적합하지 않다. 따라서 고해상도의 깊이 영상을 얻기 위해서 보간법을 수행하여 가이드 영상을 만든 후 Bilateral Filtering(BF)을 처리함으로써 영상의 품질을 향상시킨다. 본 논문에서는 2D-plus-Depth 구조에서 얻은 컬러 영상과 깊이 영상을 결합한 보간법을 통해서 깊이 영상의 특성을 살린 가이드 영상을 구현하는 방법을 제안한다. 실험 결과는 제안 방법이 기존 보간법보다 경계 영역 및 평활한 영역에서 깊이 영상의 특성을 잘 보존하는 것을 보여준다.
