현재 방송과 비디오, 신문 등의 매체를 통해 배포되고 있는 컨텐츠를 향후 인터넷을 통해 디지털 유료 서비스하기 위해서는 저작물에 대한 복제와 불법 유통을 막을 수 있는 기술의 개발이 필요하다. 현재 주문형 음악 서비스에서 사용하고 있는 방법은 서비스 제공자에서 사용자까지 전달되는 과정에서 키(Key)를 사용하여 암호화하는 방법이 있으나 일단 적법한 사용자에 의해서 부호화되고 나면 불법 복제 및 유통을 막을 수 없다는 문제점이 있다. 워터마킹 기술은 네트워크를 통해서 전달되는 멀티미디어 컨텐츠 속에 저작권 소유지의 표시를 숨겨두는 기술로서 지적 재산권 분쟁 있을 경우 재산권을 주장할 수 있는 근거가 된다. 즉, 워터마킹 기술은 인터넷을 기반으로 발달하고 있는 영상, 영화, 오디오, 만화 등의 디지털 컨텐츠의 저작권을 보호하기 위해 로고, 상표, 인감, 직인 등의 저작자 정보를 숨겨두는 기술이라고 할 수 있다. 본 논문에서는 최근 빠르게 발달하고 있는 디지털 워터마킹 기술을 소개하고 동향을 분석하여 국내의 워터마킹 기술의 발전 방향을 제시하고자 한다.

We propose to use independent component analysis (ICA) and deep neural network (DNN) to detect music sections in broadcast drama contents. Drama contents mainly comprise silence, noise, speech, music, and mixed (speech+music) sections. The silence section is detected by signal activity detection. To detect the music section, we train noise, speech, music, and mixed models with DNN. In computer experiments, we used the MUSAN corpus for training the acoustic model, and conducted an experiment using 3 hours' worth of Korean drama contents. As the mixed section includes music signals, it was regarded as a music section. The segmentation error rate (SER) of music section detection was observed to be 19.0%. In addition, when stereo mixed signals were separated into music signals using ICA, the SER was reduced to 11.8%.

This thesis describes the development of a service system for small-sized shops which support not only music broadcasting, but editing and generating voice announcement using the TTS(Text-To-Speech) technology. The system has been developed based on web environments with an easy access whenever and wherever it is needed. The system is able to control the sound using silverlight media player based on the ASP .NET 2.0 technology without any additional application software. Use of the Ajax control allows for multiple users to get the maximum load when needed. TTS is built in the server side so that the service can be provided without user's computer. Due to convenience and usefulness of the system, the business sector can provide better service to many shops. Further additional functions such as statistical analysis will undoubtedly help shop management provide desirable services.

최근 온라인게임, e-Book, 모바일콘텐츠, 포털 등 IT 기반의 새로운 서비스 산업으로서 디지털콘텐츠 산업이 급성장하고 있다. 또한, 과거 엔터테인먼트 위주의 콘텐츠산업이 미래에는 제조, 서비스를 포함한 전 산업영역에 체화융합되어 확산되고, CT 및 IT 기반의 새로운 콘텐츠 산업이 급성장할 것으로 전망되는 등 융합형 콘텐츠에 대한 관심이 증대되고 있다. 정부에서도 신성장동력으로서의 융합형 콘텐츠 산업에 주목하여, 관련 산업을 발굴육성하는데 정책적 관심을 기울이고 있다. 기존의 콘텐츠 분류체계는 영화, 음악, 방송 등 장르 중심적이어서 관련 기술의 발전 및 융합현상을 제대로 반영하지 못하는 한계점을 가지고 있다. 따라서 미래 정책추진의 기반(base)로서 효과적으로 활용되고, 콘텐츠 분야의 외연확장을 포괄하는 새로운 분류체계(taxonomy)의 정립이 요구되는 상황이다. 이에 본 고에서는 미래 정책추진 및 산업활성화에 초점을 맞추어 기존 분류체계의 한계점을 극복하는 차세대 융합형 콘텐츠 산업에 대한 새로운 분류체계를 제시하고자 한다.

인터넷기반의 서비스는 메신저, VoIP 등의 통신서비스를 수용하고, 음악, 영화, 교육, 게임 등 컨텐츠 서비스와의 연계도 자연스럽게 확대되고 있다. 차세대 통신네트워크인 BcN은 IP 전달망을 기반으로 접속, 제어, 서비스계층간에 독립적인 계층구조를 가지며, 다양한 통신+방송+데이터 융합 서비스를 안전하고 보장된 품질로 제공하기 위한 망 인프라이다. 다기능 단말과 다양한 접속 서비스 등 복합적인 통신환경을 사용하는 고객에게 다양한 융합서비스를 효율적으로 제공하기 위하여 컨버전스서비스 제공구조의 정립은 차세대통신서비스 제공자에게 매우 중요하다. 본 논문에서는 현재 BcN 컨버전스 환경을 기술하고, ITU-T에서 진행중인 통합서비스 관련 표준화 동향을 정리하며, BcN 컨버전스 서비스 제공방안을 고찰하였다.

This study examines mutual perceptions between general public and nuclear plant employees on understanding nuclear policy communication applying the co-orientation model. The total of 414 responses were analyzed including 211 of the general public and 203 of plant employees. Results indicate that agreement between general public and plant employees is relatively high, in that general public tends to have negative evaluation to nuclear policy communication, but plant employees tends to have positive one. In terms of congruence, general public perceive that plant employees might have more positive evaluation than themselves, and nuclear plant employees perceive that general public might have more negative evaluation than themselves. Finally, in terms of accuracy, general public accurately estimate how nuclear plant employees perceive on policy communication, whereas nuclear plant employees unaccurately estimate how general public perceive on policy communication.

The purpose of this study is to explore the formal and content features of the material for the Changgeuk album , which was produced and released in 1971. Changgeuk album was produced and published as a headword for "Changgeuk". However, it differs from the style of Changgeuk which is treated as a stage drama in that the narrative is developed around the commentary and dialogue in the formal aspect and the Pansori is only partially used. The styles of Changgeuk, implemented through gramophone record, radio broadcasts and television broadcasts, varied widely, unlike those of Changgeuk established in the 1930s. Pansori music wasn't the only center, and traditional performers weren't even the main members of the play. The characteristic form of the Changgeuk album is an experiment of Changgeuk that emerged naturally with radio reading and the advent of radio dramas in the 1950s and 1960s. So it is necessary to pay attention to the Changgeuk album in that it shows diverse forms of experiments conducted by Changgeuk in the newly introduced culture and media in the middle and late 20th century As for the contents of the Changgeuk album , the work embraces Lee Jong ik 's novel (1957), but develops the narrative centering on the life of Saint Sa-myung(四溟大師). And it is faithfully portraying the life of a Buddhist monk and the national salvation hero who pursued the original work. This content composition can be understood in the will of singer Lee Yong bae, the soundman who produced the album, and in the flow of historical dramas that summon the historical hero of the old country of the time to the stage. Singer Lee Yong bae reflects on his life in the past when he was full of greed and conceit through his life as a monk of Saint Sa-myung(四溟大師) and is greatly impressed by the personal aspect of Saint Sa-myung(四溟大師), and these emotions encouraged his creative will. Also, the Changgeuk record is meaningful in that it is one of the specific materials that embodies the national hero as a record and a traditional play under the discourse of the people, the nation in the 1970s.

Portable embedded systems have recently become smaller in size and offer a variety of junctions for users. These systems require high performance processors to handle the many functions and also a small battery to fit inside the system. However, due to its size, the battery life has become a major issue. It is important to have both efficient power design and management for each function, while optimizing processor voltage and clock frequency in order to extend the battery life of the system. In this paper, we calculated the efficiency of power in optimizing power rail. This system has two microprocessors. One is used to play music and movie files while the other is for DMB. In order to reduce power consumption, the DMB microprocessor is turned of while music or videos are played. Lastly, DVFS is applied to the processor in the system to reduce power consumption. Experimental results of the implemented system have resulted in reduced power consumption.

EBooks refer to electronic versions of books which are accessible via internet with forms of digital texts. In recent years, Amazon's Kindle digital eBooks has revealed the possibilities of success of the e-book market, which leads other companies to launch eBook service such as Google's eBook stores and Apple's iPad and eBook service. These reveal that the eBook market is finally showing a substantial amount of growth. Although the issue of technical support of eBook copyright protection emerges from the fast growing eBook marketplace, current technic of commercial DRM for protecting eBook copyright protection still has problems of non-comparability. Therefore, with the current technical status, DRM comparability problems, which have already occurred in music DRM environment, would also happen in eBook environment. This study suggests a standard framework to support eBook DRM comparability. When development of the standard reference software for eBook DRM comparability is completed, the sources will be registered as shareware to be open to public.
