방송사와 프로덱션 등에서 제작한 전문 방송용 콘텐츠뿐만 아니라, 개인이 온라인상에서 생성한 다양한 콘텐츠가 인터넷을 기반으로 스마트TV, 모바일 기기 등 다양한 단말을 통해 소비되고 있다. 이러한 콘텐츠가 언제, 어디서나, 서비스될 수 있도록 하기 위해서는 콘텐츠의 일관된 메타데이터 규격을 기반으로 상호운영성과 공유성을 가지도록 하는 것이 요구된다. 본 논문에서는 방송 콘텐츠 유통 메타데이터 구성 요소 및 형식에 대한 국내 표준을 기반으로 개인이 온라인상의 저작 도구를 이용하여 생성한 다양한 미디어 콘텐츠를 방송 콘텐츠 유통 메타데이터 규격에 맞도록 변환하는 동시에, 방송 콘텐츠 저작 도구에서 저작된 콘텐츠의 메타데이터를 표준 규격에 맞도록 생성하는 메타데이터 빌더를 설계하고, 이를 실제 서비스 환경에서 구현하였다.

A number of new DTV technologies have been introduced to provide crystal clear picture and enhanced sound. HDTV, in particular has four times resolution of conventional TV along with 16:9 aspect ratio. Also the introduction of the new technologies offered a valuable basis for character graphics which was only an assistant method to deliver visual images effectively. Various sizes of displays for different applications such as high definition TV and mobile multimedia services have created demands for additional features of character graphics including proper letter fonts, colors, moving effects as much. This article analyzes in what way the visual elements above can affect uses' visual perception. New CG formats designed for OSMU, one source multi use, are also suggested available to each media. For the research three groups of CG designers, art directors and productions/distribution groups are established according to production process by two Delphi surveys of TV production staff.

This study was carried out to obtain basic data for architectural plans about factors on the facilities relocation needed in management of variation type. For this, floor plans of thirteen middle schools located in Korea and Japan were compared. The results showed a successful conversion to block system according to each subject after remodeling in the schools of our country, however, a monotonous spacial composition excluded other spaces such as media space, teachers' station and preparation room was also shown. These mentioned spaces were important factors in the investigated schools of Japan. By the results of the spacial composition about each space required to the management of variation type, a space share of supplemental areas for learning activities and movement, had shown comparatively low share before remodeling, was improved to 6% and 11.6%, respectively. However, the spacial share of two areas were 16.8% and 12.9%, respectively, in the schools of Japan and it meant the distribution of area was more even than the cases of our country.

The need to maximize the exhaust pipe inside surface and to minimize exhaust resistance And Find the best point between the exhaust and the duration of contact between the two surfaces. Exhaust gas mass flow On the whole cross section of catalytic converters more uniform distribution will contribute to its usability. Based on the flow rate of fluid traces given color, Exhaust fluid resistance in the porous catalyst can be estimated, from the efficiency of the catalytic converter that is very important.

This research is aim to analyze of changing landscape and according to phenological cycle from image information of coastal environment obtained by multi-media were analyzed by camera and satellite image. The digital camera and satellite image were used for tidal flat vegetation monitoring during the construction of Sihwa lake. The vegetation type and phenological cycle of Sihwa tidal flat have been changed with the Sihwa lake ecosystem. The environment changes of Sihwa tidal flat area and ecological change were analyzed by field work digital camera images and satellite images. The airborne, UAV and satellite images were classified with the changed elements of coastal ecological environment and tidal flat vegetation monitoring carried out the changed area and shape of vegetation distribution with time series images.

Noninvasive multifrequency microwave radiometry using coaxial waveguide antenna has been investigated for a homogeneous and four layer human body model. The coupling between coaxial waveguide antenna and a. biological object is analyzed by use of the FDTD method to obtain the absorbed power patterns in the media. The object studied in this paper is a homogeneous and four-layered lossy medium. The specific absorption rates(SAR) distribution is calculated in each region by use of the steady-state response in FDTD method.

최근 인터넷을 대상으로 한 사이버 공격의 공격 경향은 분산 환경에서 다수 공격자의 대규모 분산 서비스 거부 공격(DoS)의 출현 및 해외 해커들의 국내 전산망을 우회 루트로 활용한 사례의 증가 등 고도화된 불법 행위가 점차 범죄의 강력한 수단으로 이용되는 추세에 있다. 본 논문은 기존 네트워크에서 해당 네트워크의 침입자의 트래픽 차단 방법의 취약점을 보완하여 2-MAC 인증 패킷을 이용한 효율적인 공격자 추적기법을 제안하였다. 제안된 방식은 기존 시스템에서의 NIC(Network Interface Card)의 물리적 주소인 MAC(Media Access Control)과 메시지 인증코드(MAC： Message Authentication Code)를 이용한 방식을 제안하였다.

현재 각 기업 및 기관에서 구축하고 있는 디지털 콘텐츠는 HTML을 비롯한 다양한 형식의 멀티미디어로 작성되어 있다. 따라서 타 기관에 전시된 콘텐츠 정보를 검색하거나 연동하기는 불가능하다. 뿐만 아니라 시스템을 확장하기 위해서는 전체 시스템을 교체해야하는 문제도 파생될 수 있다. 그러나 본 연구에서 제안하는 플랫폼은 기존 레거시(Legacy) 어플리케이션을 수정하지 않더라도 쉽게 신 시스템과 연동이되고 타 시스템과도 연동이된다. 또한 CORBA에 기반한 부하 분산 기법과 분산 처리기법을 도입하여 하나의 시스템에 과부하가 발생하여 전체시스템의 성능이 저하되는 문제를 방지하고 안정성을 보장하기 위하여 Fail-over 기능을 제공한다. 또한 SyncML 기법을 도입하여 여러 종류의 DBMS를 사용하는 타 기관과의 콘텐츠 실시간 공유를 지원한다. 이로써 콘텐츠를 쉽게 저장 및 유통할 수 있는 기반 환경을 제공한다.

As the online media continues to evolve and the mobile computing environment has improved dramatically, the distribution of Internet information has rapidly changed from one-sided to consumer-oriented. Therefore, measuring the interest of Internet information has become an important issue for suppliers and consumers. In this paper, we analyze the Internet information interest by analyzing the duration of real - time query by collecting data for one month by implementing real - time search word provided by domestic Internet information provider.
