As social media are increasingly being used as a marketing platform, electronic word-of-mouth (eWOM) has also become popular in both research and business areas. However, although many studies have examined the effect of eWOM, the products investigated in most of these studies, such as films or books, are not likely to be consumed daily. Therefore, in this study, we analyze the effect of eWOM on low involvement products, which are inexpensive and enough for everyday spending. Given that low involvement products have unique characteristics such as low price, we conduct an experiment using a real sales dataset related to soft drinks. We also analyze the effect of eWOM in two social media platforms. We find that eWOM influences the sales of low involvement products, but such influence is dependent on the characteristic of the social media platform. Based on these results, we suggest that marketers and retailers selling low involvement products must consider eWOM, such as reviews, and differentiate their strategies based on their focused social media platform.

The purpose of this study was to see the characteristics of oral media, which is orality and literacy combined, in order to analyze its effect on the age of Reformation and today, and to draw applicable points on the present Christian mission. The electronic age is an age of secondary orality, the orality of telephones, radio, and television, which depends on writing and print for its existence. Historically, it is a well-known fact that the shift from orality to literacy and on to electronic processing has engaged in social, economic, political, religious and other structures. With this perspective, the study was divided into two parts. In the first part, researchers dealt with the characteristics of primary oral culture, examined how it combined with media literacy and became oral media, and witnessed how reformers in the sixteenth century utilized it timely along with what the ending result was. In the second part, researcher observed the characteristics of electronic media based on literacy and orality, and presented several applicable points to the present state of the Christianity.

The Multimedia Press System is an integrated tool for electronic archiving and evaluating articles and documents from all types of media. It may be used by the following departments of a company, a government agency or other organisations in their work with the media and publications: 1. press and/or public relations 2. information and/or documentation 3. internal relations 4. investor relations 5. marketing and advertising 6. economics. It may also be used in 7. independent agencies for public relations and advertising and in 8. media-archives of publishing houses and broadcasting stations.(omitted)

The recent broadcasting environment has shifted to embrace multimedia and multi-channel features through terrestrial, satellite and cable media. This has multiplied the number of broadcasting programs. With the information on a myriad of programs provided to TV viewers, information overload occurs, and thus, the TV viewing environment is shifting to one where viewers cannot select programs passively. Thus, a growing need is emerging to ensure a personalized electronic program guide (EPG) to help individuals select TV programs according to their taste. This paper presents a personalized EPG that enables a purpose-oriented broadcasting service to provide personalized broadcasting programs in tune with the user's requirements and preferences.

제로트리 부호화 알고리즘 중 효율적이며 잘 알려진 SPIHT는 높은 메모리 요구로 인해 하드웨어 구현에 큰 어려움을 가지고 있다. 이 논문에서는 저 메모리 사용과 빠른 제로트리 부호화 알고리즘을 제안한다. 메모리를 줄이고 빠른 코딩을 위한 방법으로 다음 3가지를 사용한다. 첫 번째, 리프팅을 이용한 웨이블릿 변환은 기존의 필터뱅크 방식의 변환보다 저 메모리와 계산량의 감소를 가진다. 두 번째, 웨이블릿 변환된 계수들은 블럭으로 나누어져 각각 코딩된다. 여기서 블록은 제로트리 구조가 유지되는 STB(spatial tree-based block)이다. 세 번째, Wheeler 와 Pearlman이 제안한 NLS (no list SPIHT)를 이용한 부호화이다. NLS는 효율성에서 SPIHT와 거의 같으며 작고 고정된 메모리와 빠른 부호화 속도를 보여준다.

본 논문에서는 입체 영상 시스템 중 원 영상과 오차 영상(residual image)에 대한 효율적인 압축방법을 연구하였으며, 기준영상과 오차영상에 대해 저 비트에서도 양질의 영상품질을 얻을 수 있는 제로트리 기법을 이용하여 압축하는 기법을 제안한다. 제로트리 기법을 이용할 경우 압축 성능과 효율이 좋은 반면, 계산량이 증가한다는 단점이 있는데, 이것을 보완하기 위해 변이추정 방법은 ADLS[1] 방식을 적용하였다. 웨이블릿을 기반으로 하는 제로트리 기법을 이용하여 영상의 압축 효율을 향상시킴으로써 제한된 대역폭 내에서 높은 영상품질을 보존 할 수 있다는 것을 실험을 통하여 보였다.

This paper introduces a new texture prediction for MVC( Multi-view Video Coding) which is currently being developed as an extension of the ITU-T Recommendation H.264 | ISO/IEC International Standard ISO/IEC 14496-10 AVC (Advanced Video Coding) [1]. The MVC's prcimary target is 3D video compression for 3D display system, thus, key technology compared to 2D video compression is reducing inter-view correlation. It is noticed, however, that the current JMVM [2] does not effectively eliminate inter-view correlation so that there is still a room to improve coding efficiency. The proposed method utilizes similarity of interview residual signal and can provide an additional coding gain. It is claimed that up to 0.2dB PSNR gain with 1.4% bit-rate saving is obtained for three multi-view test sequences.

The Synchronized Multimedia Integration Language (SMIL) is a declarative markup language based on the eXtensible Markup Language (XML) to define a set of markup tags for synchronizing the timing and positioning relationships between multimedia objects. SMIL makes authoring of TV-like multimedia presentations on the Web easier for applications such as electronic commerce. We present the design and implementation of a JAVA-based SMIL player, which processes different types of media objects using multiple threads. Moreover, its cache engine detects the media type and allocates the proper cache memory for the corresponding media object.
