The ATM(asynchronous transfer mode) has the suitable solution method and the characteristics of multiplexing in the multimedia services. This paper discuss network requirements using the concepts of the multimedia communication in platform label of the multimedia tele-service and module standard. In this paper, We presents to construct structure of ATM switching for management VP(virtual path) based on ATM in the B-ISDN and compute statical multiplexing gain in the ATM-VP network on the integrate network function. Therefore We indicated that our study is effective to multimedia system in the using VP-network as ATM techniques.

전라남도 무안군 해제면에 위치한 삼보광산은 편마암류 및 유문암 내에 발달한 열극에 열수가 충전하여 형성된 열극충전광산이다. 시추 자료에서 얻은 분석 품위는 금이 0.05~10.9 g/t 이하, 은이 0.05~389 g/t 이하로 부분적으로 금·은광화작용이 인지되었다. 본 연구는 지표에서의 쌍극자, 슐럼버저 및 웨너 배열을 이용한 전기비저항 탐사와 시추공에서의 전기비저항 토모그래피 탐사를 복합하여 삼보광산에서 광화대의 분포 및 이와 관련된 지질구조를 파악하고자 한다. 3차원 전기비저항 역산의 결과는 광화대가 지표부터 약 80m 심도까지 30m의 폭을 가지며, N10°~20°E의 방향으로 240m 연장되어 있음을 보여준다. 전기비저항 영상에서 얻어진 1,000ohm-m 이하의 전기비저항 값은 시추 자료에서 확인된 금·은광화작용이 인지된 구간 및 연약대 구간과 거의 일치하였다. The Sambo mine is located in Hae-je Myeon, Moo-an Gun, Chollanamdo, which consists of host gneiss and rhyolite possessing quartzite veins with other compositions such as gold, silver, and sublimated sulfur. The ore grade estimated from the core was 0.05~10.9g/t or less in gold and 0.05~389g/t or less in silver, indicating a partial mineralization. The purpose of this paper is to understand the subsurface structures and the distribution of mineralized bodies in the Sambo mine using a combined method of Schlumberger, Wenner, and Dipole-dipole resistivity surveys on the surface and the resistivity tomography survey in boreholes. The result of three-dimensional resistivity inversion showed that the mineralized body is extended to 240m long in the N10°~20°E direction, with 30m wide and 80 m thick from the surface. The low resistivity zones (<1,000ohm-m) determined from the resistivity image were in good agreement with the mineralized bodies and weak zones identified from the logged cores.

Image segmentation is to separate areas that satisfy homogeneity and connecting ability of images simultaneously. It is an essential technique in applications in which images are treated as entities as area-based encoding. It has a long history, but it has been considered as a problem which is difficult to solve. In image processing and image recognition, removal of noise from images is very important. The presence of noise in image processing techniques may not only the functional area, but bring a different result as expected and decrease performance and rate of image recognition later. This study suggests a segmentation of images as preprocess for removal of noise in gray image, in which effective critical value is given for binary of images and the edge detection from the binary images using mathematical morphology filter.

본 논문에서는 캐릭터 애니메이션의 효율적인 동작 제어를 위하여 익스프레션을 이용한 애니메이션을 제작하였다. 익스프레션을 이용한 애니메이션은 움직임의 표현에 있어서, 자연스러운 애니메이션을 좀더 쉽고 유용하게 표현하기 위한 방법으로 캐릭터의 동작 제어점들을 분석하여 익스프레션에서 애니메이션을 제어할 수 있는 요소를 찾아 그 식에 사용하였으며, 이것을 토대로 캐릭터의 동작을 자동적으로 제어하는 애니메이션을 구현하였다. 익스프레션에 의한 애니메이션은 간편한 조작으로 자연스럽고 현실적인 움직임을 생성할 수 있다는 익스프레션의 효율성이 장점으로 나타났지만, 애니메이터에 의한 키 프레임 방식에 의한 애니메이션보다는 어색함을 보였다. This paper manufactured animation to use expression for efficient action control of character animation. Animation to use expression is method to express natural animation little more easily and usefully in expression of motion Find urea that could control animation in expression analyzing action control points of character and used in ceremony Embodied animation to control automatically action of character on the basis of this. Efficiency of expression that animation by expression can create natural and realistic action by manufacturing that is simple was expose by advantage, but showed awkwardness than animation by key frame way by animator.

The use of digital imaging technique and digital contents based on internet has grown rapidly for last several years, and the needs of digital image protection become more important. For the purpose of copyright protection on digital image, the verification of authentication techniques like content authentication, ownership authentication, illegal copy and etc are needed. Digital watermarking, the invisible encryption technique to insert digital watermark into image, the sophisticated perceptual information should be used for providing transparency and robustness of images on watermarking process. In this paper, we implement the algorithm for preventing forged attack, ownership protection and authentication by transforming the wavelet algorithms in frequency domain in terms of human visual system.

In general cases, the conventional internet connected to a terrestrial network is transmit too large medical images. To overcome this low speed transmitting rate problem of the internet, we have studied about an image division communication system as a fast telemedicine system. The Image division communication system was 5 10 times faster than the conventional terrestrial internet link. Also, we have developed a Web-based telemedicine system that can access every permitted server of hospital via the internet. Studied image division communication corrected problem of other reflex quality decline in erratic transmission of reflex by transmission speed imbalance that is problem of single communication techniques that used in existing reflex transmission. Also, could keep quality state of fixed reflex gouge abnormal transmission speed. Visual Basic and C++, ASP programming techniques were used to make our system and it can access and retrieve medical information and image through only public web browse such as internet explorer without additional specific tools. To increase the transmitting speed of our telemedicine system, JPEG method was used. In conclusion, we were able to develop a fast and public telemedicine system using the proposed image division communication system and Web technology. Image division communication system technology increased the speed of the conventional internet and Web technology extended the scope of use for telemedicine system from intrahospital to public us.

Partial discharge is studied widely by manufacture state of insulating material fare and blazing fire diagnosis system of use in phenomenon of part discharge that happen for main cause of dielectric breakdown of equipment for electric power. Use process that draw tree pattern here measuring above zero to study special quality of this electricity tree, real-time processing by image processing is proposed because reproduction of tree blazing fire process drops and pattern of tree is difficult correct quantification of tree growth by existent visual observation by involution. This research presents general process that need in image processing of tree blazing fire, and that remove various noises that happen in above zero by measuring electrical tree dividing background and complete view in measured above zero taking advantage of specially proposed complete view object abstraction techniques effectively and quantification of tree becomes easy naturally, can apply to dielectric breakdown estimate because can chase growth process of tree.
