In computer graphics, high-quality lens flares have been generated using costly offline rendering. A recent matrix-based approximation has enabled generation of high-quality lens flares suitable for real-time applications, but its quality degrades due to the lack of nonlinear patterns of lens flares. This paper introduces a method for high-quality lens-flare rendering, which includes blending of both nonlinear as well as linear patterns. The nonlinear patterns are pre-rendered or photo-graphically captured offline and stored in a look-up table. The online stage reads only the pattern by looking up the table using a light angle, hence making its performance drop negligible while greatly improving the quality.

The purpose of this study is to clarify the impact of information contents at online purchase sites of movie merchandise. The results of this study are as follows: 1) Movie-understanding information(synopsis, actors, reviews) has a meaningful influence on information service satisfaction irrespective of consumer involvement; 2) Movie-understanding and movie-going information(time, place, price, purchasing method) are alike in having a meaningful influence on online purchasing intention. However, movie-going information has a meaningful influence in case of lower consumer involvement, while movie-understanding information has a meaningful influence in case of higher consumer involvement.; 3) Information service satisfaction gives a strong influence on online purchasing intention irrespective of the level of consumer involvement. In conclusion, there is a need to improve diversity and quality of movie-understanding information to enhance consumer satisfaction. Also, it will be necessary to improve movie-understanding and movie-going information in order to enhance online purchasing intention. These results are expected to give an insight to build a creative marketing strategy of online purchase sites of movie merchandise.

This study tests consumer responses to online product recommendation service offered by a website. A product recommendation service refers to a filtering system that predicts and shows items that consumers would like to purchase based on their searches or pre-purchase information. The survey is conducted on 300 people in an age group between 20 and 40 years in a panel of an online survey firm. Data are analyzed using confirmatory factor analysis and structural equation modeling by AMOS 20.0. The results show that personalization quality does not have a significant effect on trust, but relationship quality and technology quality have a positive effect on trust. Three types of quality of recommendation service also have a positive effect on commitment. Trust and commitment are factors that increase service usage intentions. In addition, this study reveals the moderating effect of light users vs heavy users based on online shopping time. Light users show a negative effect of personalization quality on trust, indicating that they are likely to be uncomfortable to the service using personal information, compared to heavy users. This study also finds that trust vs commitment is an important factor increasing service usage intentions for heavy users vs light users.

In this paper, in today's highly complex video and broadcast operations, broadcasters are constantly challenged to reliably deliver low-latency, high-quality video to multiscreen audiences on-air and online. The Adaptive Bit Rate (ABR) protocols enable internet video to a wide range of multiscreen devices. However, video quality is often marginal and would prove unacceptable for valued linear broadcast content delivered to the Big Screen today. The Media information processing technology advances in ABR enables service providers to take control and offer quality managed linear video services to ALL screens in the home, including the Big Screen, with a single unified IP Video infrastructure. The New Multiscreen-Assisted ABR (MSA-ABR) delivery management system proposed using Cloud based multicast-assisted ABR for a broadcast facility that performs routing of contribution content and online publishing services within a virtual, centralized cloud infrastructure.

인터넷 인구 증가와 정보자원 고도화에 따라 인터넷 사용자들은 새로운 형태의 커뮤니케이션을 스스로 발전시켜왔고 이러한 흐름이 최근 UCC의 폭발적인 증가로 이어졌다. 하지만 아직까지 사용자들이 UCC를 공유하는 동기에 대한 명확한 설명은 부재한 상황이다. UCC는 기존에 지속적으로 연구되어 왔던 온라인 커뮤니케이션 형태인 가상공동체나 온라인 구전의 참여 동기를 상당부분 계승하고 있으나 최근의 인터넷 문화와 기술 수준 변화에 부합하는 새로운 참여동기를 포함하고 있는 것으로 보여진다. 본 연구에서는 이러한 UCC 제작 동기를 파악하기 위해 UCC 제작 경험이 있는 300명의 샘플을 대상으로 설문을 수행했고, 이를 통해 UCC 제작 동기가 Self-Creation Motive, Community Commitment Motive, Self-Expression Motive, Community-Relatedness Motive, Reward Motive로 요인화될 수 있음을 밝혀냈다. 본 연구의 결과를 통해 UCC를 비즈니스 모델로 하는 온라인 기업들은 보유 고객의 UCC 공유 동기 성향을 파악할 수 있고, 이를 통해 고품질의 UCC를 확보하기 위한 차별화된 전략을 제시할 수 있게 될 것이다.

전자상거래는 우리나라 뿐 아니라 여러 선진국에서 새로운 비즈니스 환경으로 급속히 개발 되고 있으며, 아울러 기업에게 위협 요인과 동시에 새로운 기회로 다가오고 있다. 본 논문에서는 기존 전자상거래 모델에서 벗어나 쇼핑몰 관련 그룹을 제조. 유통. 생산업체인 공급자(B)그룹과 제품을 공급받아 소비자에게 직접 판매하는 도·소매(B)그룹 그리고 제품을 구매하는 소비자(C)그룹으로 나누고 서로 윈 윈(Win Win) 할 수 있는 효과적인 전자상거래 모델(B2B2C)의 사례를 연구하고자 한다. 이러한 기업 공동 B2B2C 전자상거래 모델을 웹 어플리케이션 전문제작회사인 D개발회사가 본 시스템 솔루션에 2개월을 소요·개발하여 적용한 결과 고객은 온라인-오프라인 상에서 상호적으로 대응 할 수 있었고, 제품에 대한 품질보증 역할을 더할 수 있어 기존 단골 고객을 중심으로 효율적인 수익을 창출 할 수 있는 전자 상거래 모델을 구축하였다. 즉, 기존의 오프라인의 점 조직 형태의 판매망을 통해 온라인 전자상거래와 상호 유기적으로 도움을 줄 수 있다. 이는 B2B2C의 새로운 전자상거래 모델 제시와 더불어 기존고객을 관리할 수 있는 CRM 도입 효과를 가져와 향후 전자상거래를 통한 온라인 유통망형성에 있어 새로운 솔루션 개발의 기반기술이 될 것이다.
