Optical discs' capacity has increased. In case of Blu-Disc, it can store data up to 25 GB. Due to the large capacity, it can substitute tape devices for the use of backup. However, optical discs' surfaces are exposed so that it can lose data easily by exterior damages like scratches. Therefore additional reliability must be provided to maintain data for a long time. In this paper, we suggest a writing technique that gives optical discs additional reliability. Redundant data, generated by LDPC codes, are stored in disc along with the original data. These original data and redundant data are scattered over the disc to avoid losing a large part of data with one scratch. By deploying data with the distance that provides the reliability a user wants, we can enhance optical discs' reliability.

This study focused on the effects of Korean cosmetics selection attributes on Mongolian consumers' brand reliability and purchasing intentions. We are also to verify the relationship impacts between consumers brand reliability in advertising media and the purchase intention on the type of promotion. 255 questionnaires were collected for Mongolian consumers and analyzed using SPSS and AMOS. The analysis shows that product price, image and quality that they have a positive effect on brand reliability, while familiarity has not had a meaningful impact on brand reliability. Moreover, brand reliability has been shown to have a positive effect on purchasing intention. As a result of the adjustment effect test according to advertising media, the relationship impacts between product selection attributes and brand reliability were shown positive effect in part. Finally, the type of sales promotion were found to have a controlling effect between brand reliability and purchasing intention. These results show applicable implications for Korean cosmetics companies in terms of marketing and operations when entering Mongolia's cosmetics industry.

This paper investigates audience perception on news content through comparison analysis on Comprehensive Programming Channels, TV chosun, JTBC, Channel A, and Terrestrial Broadcasting 'KBS'. How sensationalism created by video news affect audiences' credibility on news and media. The results shows that Comprehensive programming channels are assessed more sensational than terrestrial broadcasters by audience. Additionally, Comprehensive programming channels are assessed to get a lower credibility than terrestrial broadcasters by audience in the analysis of news and media credibility, comprehensive programming channels and terrestrial broadcasters. As a result, comprehensive programming channels showed lower news credibility and media credibility compared to that of the terrestrial broadcasters. This means that comprehensive programming channels must do the best not only recovering credibility from audiences but also constructing position as national broadcasting media.

The purpose of this study is to test the influence of CSR publicity(positive vs. negative) on the corporate image and customer loyalty. Especially this study is focused on the moderating effect of media credibility and the mediating effect of corporate image between CSR publicity and customer loyalty. The results of this study are as follows. 1) The influence of CSR publicity on the corporate image appears more in the negative information than the positive one. 2) The moderating effect appears in media credibility. Namely, in the case of positive CSR information, the influence of CSR publicity on the corporate image appears high only in high credibility of media, but it does not in low media credibility. Whereas, in the negative information, there is no differences of negative influence on the corporate image nevertheless of media credibility. 3) The higher the corporate image is, the higher the customer loyalty is. The results of this study implicate that credibility of CSR publicity is very important factor on the corporate image and customer loyalty and media credibility is another one in credibility of CSR publicity.

Theoretical review of the PR activities was initiated using Lasswell's (1948) SMCRE model to evaluate the indicators of the collaborative programs with NGO and the outcome of the activities promoting energy-saving programs. The indicators were then set based on a case study by Nho Younhwoo (2012). This paper aims to develop evaluation indicators for the activities promoting energy-saving programs and evaluate how energy consumers recognize the reputations of PR agencies (sender), PR content (message), PR media outlets (channel), and the degree to which such PR activities induce energy-saving behaviors.

People receive information through various media, such as newspapers, TV, radio, magazines, or internet, etc. In particular, through the development of the internet and smart-phone they can interact with media and receive information in real time via handheld devices. However the types of information and media could affect the reliability of news information. In this study, it was the main interest how the usability in the new media with the interactivity, such as a desktop, tablet, and smart-phone affects the user's evaluation on the contents displayed by the different new media. Therefore, the present study was conducted to investigate the effect of the usability from the different display size of media and the different contents of articles on the reliability of information empirically. The results showed that the contents of the articles interacting with different devices affect the reliability of information. These findings propose the considerations on the effects of characteristic usability of the new media in the stages of the development of the media contents.

연속 매체, 특히 비디오 데이타에 대한 일반 사용자 연산에는 재생뿐만 아니라 임의 속도 탐색 연산, 정지 연산, 그리고 그 외 다양한 연산이 있다. 이 연산 중에서 원하는 화면을 빨리 찾는 데에 유용한 고속 전진(FF: fast-forward)과 고속 후진(FB: fast-backward)은 재생 연산과는 달리 비순차적인 디스크 접근을 요구한다. 이러한 경우에 디스크 부하가 균등하지 않으면 일부 디스크에 접근이 편중되어 서비스 품질이 떨어진다. 본 논문에서는 디스크 배열을 이용한 저장 시스템에서 디스크 접근을 고르게 분산시키기 위하여 '소수 라운드 로빈(PRR: Prime Round Robin)' 방식으로 연속 매체를 디스크에 배치하는 기법에서 문제가 됐던 낭비된 디스크 저장 공간을 신뢰도 향상을 위해서 사용하는 '그룹화된 패리티를 갖는 소수 라운드 로빈(PRRgp: PRR with Grouped Parities)' 방식을 제안한다. 이 기법은 PRR 기법처럼 임의 속도 검색 연산에 있어서 디스크 배열을 구성하는 모든 디스크의 부하를 균등하게 할뿐만 아니라 낭비됐던 디스크 저장 공간에 신뢰도를 높이기 위한 패리티 정보를 저장함으로서 신뢰도를 향상시킬 수 있다. 신뢰도 모델링 방법으로 조합 모델과 마르코프 모델을 이용해서 결함발생율과 결함복구율을 고려한 신뢰도를 산출하고 비교.분석한다. PRR 기법으로 연속 매체를 저장하고 낭비되는 공간에 패리티 정보를 저장할 경우에 동시에 두 개 이상의 결함 발생 시에 그 결함으로부터 복구가 불가능하지만 PRRgp 기법에서는 약 30% 이상의경우에 대해서 동시에 두 개의 결함 발생 시에 저장한 패리티 정보를 이용한 복구가 가능할 뿐만 아니라 패리티 그룹의 수가 두 개 이상인 경우에는 두 개 이상의 결함에 대해서도 복구가 가능하다.Abstract End-user operations on continuous media (say video data) consist of arbitrary-rate search, pause, and others as well as normal-rate play. FF(fast-forward) / FB(fast-backward) among those operations are desirable to find out the scene of interest but they require non-sequential access of disks. When accesses are clustered to several disks without considering load balance, high quality services in playback may not be available. In this paper, we propose a new disk placement scheme, called PRRgp(Prime Round Robin with Grouped Parities), with enhanced reliability by using the wasted disk storage space in an old one(PRR: Prime Round Robin), in which continuous media are placed on a disk array based storage systems to distribute disk accesses uniformly. The PRRgp can not only achieve load balance of disks consisting of a disk array under arbitrary-rate search like PRR, but also improve reliability by storing parity information on the wasted disk space appropriately. We use combinatorial and Markov models to evaluate the reliability for a disk array and to analyze the results. When continuous media like PRR are placed and parity information on the wasted disk space is stored, we cannot tolerate more than two simultaneous faults. But they can be recovered by using stored parity information for about 30 percent as a whole in case of PRRgp presented in this paper. In addition, more than two faults can be tolerated in case there are more than two parity groups.

Due to the various reasons reducing the advertising effects in such as message reliability declining, target segmentation, and information technology, creative becomes more important than ever before. And this is more true in print advertising than electronic ones. The purpose of this study is to support to develop more effective advertisement in print advertising. Parody advertising, a postmodernic technique, effectiveness was tested empirically. Top-of-mind awareness, reliability toward advertising, attitude toward advertising, attitude toward brand, and purchase intention were adapted as a scale to measure the effectiveness of parody and non-parody advertising. Result proved the parody advertising shows higher effects than non-parody one. Conclusively saying that parody could be one of the possible ways to increase effects on print advertising to survive from the heavy competition and low attention.
