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.

There is much interest on information communications owing to the rapid development of network and IT(Information Technology). Analog signals are converted into digital signals for information communications. However, it is very difficult to completely erase the distortion induced during the conversion of analog signals such as voices and images into digital signals. Existing audio graphic equalizer requires very complex processes to calculate the gain and coefficients of the higher-order filter which is required to generate natural sound and to satisfy the need of each person. Unfortunately it is uneconomical and very difficult to embed the existing digital audio equalizer in the system because of the complexity of the existing digital audio equalizer for high quality sound. This paper discusses the design of a new digital audio graphic equalizer(DAGEQ) which can improve system performance and the quality of audio sound, and can be embedded in the system. This new DAGEQ is designed so that the gain can be controlled automatically. The automatic control of coefficients and gain empowers real time processing and the improvement of audio quality.

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.

This study seeks to propose the virtual costume's pipeline production in digital fashion show which is based on the unique characteristic combining computer graphic technology and traditional fashion design. This study analyzed the fabric materials based on Korean traditional costume to create a virtual Hanbok for the digital fashion show, and conducted the group of professional's satisfaction statistics through the experiment to verify the realistic usability. The contents of primary process of producing virtual Korean costume is analyzed by summarizing the thickness, weight, and color as the three essential fabric properties required for virtual Hanbok. In addition, virtual costumes are compared with real Hanbok based on the usability survey to evaluate the positive research result by forty graphic experts. The purpose of this study is to present the guideline of essential material analysis of the fabrication to digital fashion show in the virtual clothing production.
