This is the study for system model of digital contents quality assurence. We develope a lot of digital contents which are games, mobile contents, e-learnning contents etc. The most of case that contents have to think about export to abord. Unfortunatly we still not to much think about digital contents quality. This paper propose the system model of digital contents quality assurence base on the process lifecycle for prepare international competation.

본 사례연구는 한국정보사회진흥원에서 개발한 디지털콘텐츠의 표준식별체계인 UCI(Universal Content Identifier)를 (주)누리미디어 보유의 약33만 건 콘텐츠에 적용한 사례와 비즈니스 모델을 소개하고 있다. UCI란 '디지털콘텐츠의 유통활성화' 를 이룩하기 위한 목적으로 도입하는 기술로 개별 디지털콘텐츠에 식별기호를 부여하는 기술이다. 본 사업은 UCI코드 체계를 이용하여 콘텐츠 관리 시스템을 구축하는 것을 목표로 하고 있다. UCI-RA시스템 구축이후 기대효과로는 콘텐츠 제공과 관련된 업무에 인적, 물적 비용을 절감하고, 신규 콘텐츠 발굴 및 개발이 용이하도록 하였다. 또한 서비스 운영과정에서는 기 확보된 콘텐츠를 비즈니스화 하여 신규 수익창출의 모델로 육성할 수 있다. 한편 콘텐츠 소비과정에서는 콘텐츠 검색의 용이성 및 구매 용이성 증대를 통해 양질의 콘텐츠를 유통하는 것이다. 아울러 운영기업의 콘텐츠 등록 및 운영과정에서의 유료콘텐츠 정산주기율 단축, 콘텐츠 품질 고객만족도 제고 등의 효율성을 증가할 수 있다.

The present thesis aims to analyze in consideration of recent changes in teaching environment in the universities the commercial digital contents and e-learning courses provided by the libraries, and to propose the ways to encourage university library service needed under the current situation. A survey of professors and students upon the quality of commercial digital contents service provided by the libraries in I University was made to measure its influence upon e-learning courses. The quality of commercial digital contents service provided by libraries was measured through Digital Library Service Quality Index (which will be referred as DL-SQL Model from here), which is used as a model to examine the Digital Library Service, with partial adjustments of 4 levels (information system service, digital books service, customer service quality, and customer community service) and 7 components (search possibility, an exclusive organization and interface, accessibility, digital books, customer support service, personalized service, and customer community). Among the library services in regard to digital contents, "customer service" and "customer community service" were analyzed to have stronger influence upon e-learning teaching and studying than quality-based service for "information system" and "digital books". Consequently, it is concluded that customized information service provided by the library for the professors who teach e-learning courses and their students is more influential to supporting e-learning courses than quantity pushing service through purchasing commercial digital contents, upon which the direction of digital contents policy to provide library services for e-learning courses should be based.

Broadcasting environment of present our country is greeting period of transition that undergo a change to digital broadcasting system in analog broadcasting system continued for last several decades. With change of these broadcasting environment interest about various digital broadcasting contents industry that fill to digital broadcasting infra and unlawfulness reproduction prevention technology far digital broadcasting contents of high added value is rising. According as is converted to digital broadcasting environment interest about reproduction prevention is well-founded to be risen sensitively. First analog broadcasting environment can not remove perfectly error at transmission in receiver, but can reconstruct contents such as original by error correction function in receiver in the case of digital broadcasting environment. Secondarily, although quality of copy is dwindled than original repeat reproduction in case of analog, many copies are available innumerably regardless of number of times of copy keeping quality such as original in the case of digital And third element is possible easily to anyone to on-line along with development of internet in case of digital contents unlike analog. Under these background, this thesis wish to design and implement digital contents protection system to prevent unlawfulness reproduction and distribution of digital contents using Triple DES algorithm.

To IT convergence study tourism the convergence of IT and tourism in recent years has emerged as a discipline in the future. The purpose of this study, quality of tourism information systems using u-smart content information about design and implementation. This create the basic processes and data that you can analyze the average propensity of tourism and tourism tourists tourist information quality by implementing patterns of information in the template library content can be. Tourist information and tourist's propensity to take advantage of smart apps and XMI created and implemented by the appropriate content information on the quality of the tourism information content can be seen in real-time, this paper have the advantage of being Connection relationship meta-model through the inter-related processes, as well as Smart App can be meta-modeled. Quality by implementing the content of the information tourism information and helps in the development of the future tourism policy, in which you can design a digital model to determine the propensity of tourists.

최근 UHD 방송서비스에 대한 관심이 고조됨에 따라 고품질 방송 콘텐츠 보호에 대한 요구가 증가하고 있다. 이에 따라, DVB, MPEG, ATSC 등 국제 표준단체에서는 기존 방식보다 보안 성능이 우수한 디지털 방송 보호 규격을 논의하고 있으며, 디즈니, 파라마운트, 소니 픽처스 등 세계 주요 콘텐츠 제작사들이 설립한 비영리 기관인 MovieLabs 에서도 고품질 콘텐츠 보호를 목적으로 AES-128 또는 그 이상의 강도를 갖는 콘텐츠 암호화 알고리즘을 필수적으로 사용하도록 규정하였다. 본 논문에서는 디지털 방송 보안을 위해 널리 사용되고 있는 DVB-CSA 및 AES-128 보다 보안성능이 우수한 것으로 알려진 방송 콘텐츠 암호화 규격인 DVB-CSA ver3 표준 규격 기반으로 설계 및 구현된 스크램블 시스템에 대해 소개한다.

This paper studies the effect of content information quality of u-tourism information system on flow theory and satisfaction. The purpose of the research is to generate and propose flow-related information to satisfy tourists with content information quality. The meaning of this paper is to derive success factors for verifying satisfaction of content information quality to tourists, establish hypotheses as research models, and evaluate verification. The differentiation of this study is the design implementation of u-fusion tourism information system by combining flow relation information with flow theory. The contribution of this paper is the generation of flow related information and the elicitation of success factors of contents quality of u-tourism information system. The advantage is that tourists can be patterned by symbolization and the pattern can be illustrated. The limitations of this paper are limited to small areas, and the lack of objectivity is required and future tasks are needed to compensate for them.

This paper focus on the digital media quality of one source multi-use for the vitalization of Korean classical literature. This paper examines the structural relationship between the quality of digital media and learning satisfaction/sustainable use intention through digital media. For this we used the case of The 'Encyclopedia of Korean Local Culture(www.grandculture.net)'. Thus we conducted a survey of 418 high school students attending a classical literature class which used the local culture DB. The result of this study demonstrates that quality of media content and media service quality affect the learning satisfaction even if media system quality does not affect the learning satisfaction. Learning satisfaction affect strongly. The result of multi regression showed that system quality increased the learning satisfaction in the high group, but system quality did not effect the learning satisfaction in the low group. These results indicate that if system quality is enhanced, learning satisfaction will be slightly increased, and if quality of contents and services is enhanced, learning satisfaction will be strongly increased.
