SEDRIS(Synthetic Environment Data Representation and Interchange Specification) has been defined in the ISO JTC1 SC24 WG8 standardization group. This paper describes the development of a 3D viewer that can read, render, and transform all the kinds of 3D objects defined by the SEDRIS data representation. The viewer is composed of a tree view for the data structure, an attribute window for presenting the attributes, and a rendering view for playing and transforming the 3D representation of each object. Its feature is the point that it provides the method of describing all the attributes of the object including scalable unit information as well as the 3D data visualization.

This paper describes a multimedia synchronization model based on the MPEG-4 (Moving Picture Expert Group) system, which integrates, manages and transfers multimedia objects such as audio, video, image, etc. BIFS(Binary Format for Scene) assigns the presentation and property of the object, and organizes a scene. The paper illustrates the methods of generating the scene description tree, of defining and adding the temporal relationship nodes to the original BIFS tree structure, and of managing them between objects during the playback of multimedia objects. It includes also the development of a MPEG-4 authoring system that users could define the temporal relationships of themselves, and let multimedia objects play.

본 논문에서는 네트워크를 통해 멀티미디어 정보를 생성하고 검색할 수 있는 환경을 네트워크 사용자에게 제공하는 멀티미디어 정보서비스 플랫폼인 텔레서브(TeleServe) 개발에 대해 기술한다. 텔레서브는 서버, 클라이언트, 멀티미디어 정보 설계를 관리하며 네트워크 사용자가 요구하는 정보를 제공하는 역활을 한다. 클라이언트는 서버가 제공하는 정보를 통합하여 디스플레이해 주는 역할을 한다. 저작도구는 네트워크상에서 서비스 시나리오에 따라 모든 멀티미디어 정보를 생성해 준다. 이외에 본 논문에서는 텔레서브를 이용하여 개발한 서비스 응용인 텔레마켓팅시스템에 대해서도 기술한다.
Bulk Ge-Se-Bi Chalcogenide Glass의 비정질 및 결정화에 따른 전기전도도의 변화
이명원,강원호 단국대학교 신소재기술연구소 1992 신소재 Vol.2 No.-
Amorphous Semiconductor로서 Chalcogenide계의 Ge-Se-Bi 계 비정질화와 결정화 실험을 통하여 전기전도도를 평가코자 하였다. 시료의 조성 범위는 Ge_15-25 Se_65-85 Bi_25-15의 범위에서 5N의 Ge, Se, Bi metal 분말을 사용하였다. 시료는 석영관에 진공 장입후 용융시켜 비정질화하였다. 이때 열처리 조건은 1000℃에서 10시간 동안 가열하였으며 급냉 조건은 3834℃/sec로 처리 하였다. 비정질 sample의 결정화는 결정핵을 형성 시킨 후 온도 변화 및 시간의 변화를 주면서 결정을 성장 시켰으며, 이때 Bi_2Se_3와 GeSe_2 결정상을 관찰 할 수 있었다. 유리화 영역은 Ge 15 at%, Se 70 at% 이상, Bi가 10 at% 이하일 때 비정질화가 용이하였다. Ge를 20 at%로 고정시 Bi의 at% 함량이 증가함에 따라 전기전도도가 증가했으며 Bi가 7.5 at% 이상일때 급격한 전도도의 증가를 가져왔다. Ge_20Se_77.5Bi_2.5 조성의 결정화 경우 330℃에서 4 hr 유지시킨 경우의 전기 전도도가 가장 양호 하였다. The purpose of this study was to evaluate electrical conductivity of Ge-Se-Bi system Chalcogenide glass as a amorphous semiconductor by observing its dissolution and crystallization. In this experiment, Ge,Se,Bi metal powders in the range of Ge_12-25, Se-65-85, Bi_2.5-15 was used. The mixed metal powder were put into a vaccous quartz tube and then melted. The condition of heat treatment was to dispose it to 1000℃ heat for 10 hours and then rapidly quenched it at 3834℃/sec. The crystallization of the fused sample ripened as the change of temperature and time, after the crystal core was formed. At that time it was possible to observe the state that Bi_2Se_3 and GeSe_2 were crystallized. And the amorphousness was well progressed when Ge was over 15 at%, Se was over 70 at%, and Bi was under 10 at%. As for bulk, when Ge was fixed to 20 at%, the conducting of electricity was increased as Bi gained at%. In the experiment on Ge_20, Se_77.5, and Bi_2.5, the crystalization was most vigorous when they were kept at 330℃ for 4 hours.

This paper describes a method of implementing the game virtual environment with an interactive environment information provider so that it could insert the real world information related to the specific location in the virtual environment. It also includes the game navigation and control in the virtual environment. The information provider is intended to implement a semantic virtual environment for 3D applications. It provides the function of inputting a realtime, location-based environmental information related to the real world during navigation. The paper includes the game scene generation and management, terrain mesh data processing and map editor collision detection, and game navigation control.
