86아시안게임과 88올림픽을 계기로 필름시장이 꾸준한 성장을 이루다가 97년 IMF와 함께 급격히 하락하기 시작해 2000년 인구 1인 당 1롤 정도의 소비량을 보이고 있는 가운데 2001년도 역시 낙관적이지 않은 거시경제지표와 디지털카메라 및 장비의 보급으로 또 다른 양상을 보여줄 것으로 보인다. 하지만 디지털제품이 필름과 미니랩시장을 대체하기에는 상당한 시간이 걸릴 것으로 예상된다.

Each on-board equipment providing navigational and engine information has different signals. These signals should be analyze, be transformed to the standard digital form and be transmitted to each client on board through the earlier developed ILU (integrated LAN unit). Therefore this paper was to analyze the signals of each equipment for navigation and engine and was to use the serial technology necessary for the equipment and IDU (information display unit). And this paper was then to develop an SIU (ship's interface unit) and to test it onboard.

한국 방송은 새로운 역사를 거듭 쓰고 있다. '거듭'이라는 단어의 의미가 주는 무게는 남다르다. 남북화해 무드에 편승해 백두산과 한라산에서 남북동시 3원 생방송을 위시해 방송의 날(매년 9월 3일)을 기념해 KBS와 MBC가 디지털 방송을 시작한 것이 그것이다. 이들 양사보다 한발 앞선 SBS는 2000년 8월 31일부터 디지털 시험 방송을 시작함에 따라 지상파 3사는 모두 디지털 방송시대에 돌입하게 되었다. 이들 지상파 방송 3사는 디지털 방송을 위해 1999년 1월부터 장비도입 등 준비작업에 박차를 가한 결과라 시청자는 물론 방송 업계와 콘텐츠 관련 업계는 모두 새로운 디지털 콘텐츠 시대를 실감하고 그 준비에 하루 24시간이 늦가을 하루해 만큼 짧게 느끼고 있다.

디지털 기술 발전에 따른 현상은 새로운 영상 제작 분야의 원동력이 되고 있다. 이러한 상황에서 교육기관에서 담당하고 있는 디지털 영상 제작 교육의 활성화와 저변확대는 산업현장과 연계될 수 있도록 실무중의 교육으로 발전되고 있는 것이 특징이다. 또한 디지털 장비의 저변확대에 따른 다양한 디지털 콘텐츠의 생산은 새로운 디지털 문화를 형성하는 원동력이 되고 있다.

The introduction of smart factory digital twins is a concept that has already been proposed to increase productivity in the manufacturing industry through CPS(Cyber Physics System), and has been applied to specific industrial process stages or partially introduced in stages where simulation is required. However, with the recent development of the 4th Industrial Revolution technology, it is receiving attention again along with XR (Extended Reality) technology. However, because there are not many effective cases, this study analyzed the devices, equipment, and technology of the manufacturing process to build a digital twin applying digital threads and synchronized signals and information to control, remote control, and produce intelligent process automation equipment. A platform capable of analyzing information was proposed and developed. Through this, we designed and built an XR content service platform that can support artificial intelligence and developed it to enable control, remote control, and analysis of production information. A possible platform was proposed and developed. We hope that this study will be helpful in conducting research on many cases, and in the future, expanded research on increasing productivity in each part of the process and production is needed through intelligent models.

This study describes the design and implementation of EGSE for Digital Satellite Communication. The EGSE is a equipment that evaluates digital satellite communication and requires precise and accurate measurement. EGSE consists of a PLDIU and IIU(Instrument Interface Unit), Up/Down converter for SHF band, Modems to verify the Digital Satellite Communication. The EGSE was used for performance verification and space environment test such as thermal vacuum after developing digital satellite communication.

In this paper, we proposed the microcalcification detection algorithm which is based on wavelet transform and automatic thresholding method in the X-ray mammographic images. Digital X-ray imaging system is essential equipment in the field diagnosis and is widely used in the various fields such as chest, fracture of a bone, and dental correction. Especially, digital X-ray mammographic imaging is known as the most important method to diagnose the breast cancer, many researches to develop the imaging system are processing in country. In this paper, we proposed a microcalcifications detection algorithm necessary in the early phase of breast cancer diagnosis and showed that a algorithm could effectively detect microcalfication and could aid diagnosis-radiologist.
