In the integrated systems, that is integrated digital TV(DTV) internet and home automation, like home server, is needed integration of digital TV video signal and computer graphic signal. The graphic signal is operating at the high speed and has time-divide-stream. So the re-request of data is not easy at the time of error detection. therefore EDAC algorithm is efficient. In this paper, we show a scheme, that is integration of graphic and dtv format signal for DTV monitor display. This paper also presents the efficiency error detection auto correction(EDAC) for conversion of graphics signal to DTV video signal. A presented EDAC algorithms use the modified hamming code for enhancing video quality and reliability. A EDAC algorithm of this paper can detect single error, double error, triple error and more error for preventing from incorrect correction. And it is not necessary an additional memory. In this paper The comparison between digital TV video signal and graphic signal, a EDAC algorithm and a design of conversion graphic signal to DTV signal with EDAC function in DTV system is described.

3D SCAN enables easy human body measurement via a digital method in the process of film costume production which used to be done manually. Software-oriented computer graphic, which integrates 3D SCAN data in the process of manual film costume production, can induce quick and diverse design outcomes. While, 3D PRINT, which integrates computer graphic data in the process of manual film costume production, can automate the process of special costume production using a digital method. Integration of 3D Scan + Computer Graphic + 3D Print using integrated platforms for tailored costume production as developed in this study allows significant reduction of costume production period and costs. It also allows efficient integration of costume production outcomes in various industries related with OSMU contents in particular. In other words, using it, we can create a new business market that integrates multiple areas of film content, drama content and game content.

This paper presents computer graphics applying the traditional Korean house(Hanok) style interior to unit-care space of Welfare Facility and proposes the possibility as interior design and construction materials. In this paper, the proposed computer graphic-based model is a single-story building that provides convenient traffic between rooms. Computer graphic-based model is presented by Auto CAD, 3D program (Sketch-UP v.8), rendering program (Podium v.2) based on the traditional Korean house and related work of unit-care welfare facility. Computer graphic-based model that combined unit-care and the traditional Korean house has the following characteristics. In each room of living space, wallpaper and flooring Korean paper(Hnaji) is considered and windows, door, furniture of traditional pattern were placed. The living room(Daechung) that is representative of the traditional Korean house and the corridor (toenmaru) are the elements to save the image of the traditional Korean house as much as possible. Especially, the corridor (toenmaru) is placed to conveniently use in nursing-care facility and home-care support facility. A public space is placed around the inside court (An-madang), while the living space (unit-care) has a sense of independence by separation. Bathroom and kitchen have a modern design for functionality than aesthetic elements.

There has been more increased the development of 3D technique since many 3D contents of 3D graphic model, 3D mobile/computer game, and 3D CAD have been serviced in Web or industry fields. Therefore, the watermarking system is more required to protect the copyright for 3D contents. Currently there has been researched about the watermarking for 3D graphic model of mesh or NURBS. However, watermarking technique based on CAD design drawing leaves something to be desired yet. This paper proposed the watermarking technique for 3D CAD design drawing using Line and Arc components. After drawing out Line and Arc components from designed drawing, we embed the watermark into both the length of Line component and the radius of Arc component. Experimental results verified that the proposed algorithm satisfies the transparency about watermarked drawing and also has the robustness against several attacks by using public CAD tool.

네트워크와 IT산업의 급속한 발전과 더불어 정보통신에 대한 관심이 매우 커지고 있다. 정보통신 분야에서는 주로 디지털 신호가 사용되므로 아날로그 신호를 디지털 신호로 변환하여야 한다. 그러나 음성이나 영상과 같은 자연상태의 아날로그 신호가 디지털 신호로 변환될 때 발생하는 왜곡을 제거하는 것은 매우 어려운 과정이다. 원음 또는 각자 취향에 맞는 음질을 발생시키기 위해서 기존의 오디오 그래픽 이퀄라이저는 매우 복잡한 과정을 통하여 고차의 필터 계수 및 이득을 계산하였다. 그러므로 이러한 요구사항을 만족시키기 위해서 는 시스템이 복잡하여 경제성이 떨어지고 타 시스템 내부에 장착할 수가 없었다. 본 논문에서는 오디오 음질의 개선과 시스템 성능향상 및 내부 장착이 가능한 새로운 디지털 오디오 그래픽 이퀄라이저를 설계하였다. 또한 필터 계수 및 이득을 자동으로 처리함으로써 실시간 처리가 가능하고 음질이 향상되도록 하였다.

KAERI is developing the Advanced Spent Fuel Conditioning Process (ACP) as a pre-disposal treatment process for spent fuel. In this process, the management process must operate in intense radiation fields as well as in a high temperature. Therefore, remote maintenance has played a significant role in this process. Hence suitable remote handling and maintenance technology needs to be developed along with the design of the process concepts. To do this, we developed the digital mockup for the ACP. The digital mockup provides the capability of verifying the remote operability of the process without fabrication of the process equipment. In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in the digital mockup. Through utilizing this graphic simulation in this digital mockup, general guidelines can be established for designing equipment intended for remote handling and maintenance. Also, the designer of the equipment that must be remotely maintained should ensure that there is adequate access to the process equipment. The graphic simulator will substantially reduce the cost of the develo363pment of the remote handling and maintenance procedure as well as the process equipment.
