Since the national standard topographic map is made by DXF format which is the results of the National Geographic Information System project and lots of CAD data and scanners can be used to acquire the data easily, the imports of existing DXF file will decrease the costs and time for data acquisition process. In addition, the spatial data such as topographic map should be able to convert to the middle file format such as PostScript in order to be exported into other systems. For this purpose, I design and implement three units of modules, which are File Manipulation Module, MVF Import Module, and MVF Export Module. Finally, I verify the actual transformation of topographic map that are DXF file format by conducting the series of tests.

This study analyzes the characteristics of good impression using speech manipulation scripts and investigates the characteristics of preferred speech voice. Fourty male and female college students participated in this study. They have been exposed to the Gyeongsang dialect spoken by their friends and family for more than 15 years. Two sample voices(1 male and 1 female), considered as giving good impression, were subject to voice analysis. Two students were asked to read the sample paragraph of 'Walking' and their voice samples were analyzed through Praat. The collected speech data were manipulated into 4 different sets by changing pitch level, degree of loudness and speech rate. First, both men and women received good impression more from pitch-lowered sound than from the original one. Second, men tended to receive good impression more from slightly louder voice than from the natural-pitched one. Third, it was shown that men often felt more drowned to a voice at slightly faster speech rate than at the original speech rate. Overall, both male and female listeners favored lower pitch over the original pitch. Men tended to prefer louder voice sound while women preferred less loud one. Men received better impression at a lower speech rate but women at a faster speech rate.

아주 오래전부터 우리 인류에게 영향을 미친것 중 두가지는 "새로운 시각을 표현하려는 것" 과 "지속적인 영상 신기술 개발" 일 것이다. 본 논문은 사이버 공간상에서 시각화 기법과 애니메이션 기법을 사용하여 컴퓨터와 인간사이에서 발생할 수 있는 가시화(Visualization), 조작화(Manipulation), 상호작용(Interaction) 등의 기술을 제공해서 사용자들이 흥미를 갖는 가상적 사이버 공룡 시스템을 제안한다. 사이버 공룡 시스템 구성은 "공룡 퍼즐 맞추기", "공룡애니메이션", "공룡 이름 맞추기", "공룡 그림 맞추기", "공룡 그리기", "공룡 그려보자",로 구성되어 있으며, 보조 버튼으로 "공룡 캐릭터", "공룡 아이콘", "공룡 원시자료"로 되어 있다. 본 시스템은 Java와 JavaScript를 이용해서 구현했으며, 사용자가 직접 공룡 자료를 제어하면서 컴퓨터와 인간 사이에서 발생할 수 있는 시각화 등을 디지털 애니메이션 기법을 이용해서 해결하고 데이테 베이스화 했다.

This paper describes the design and implementation of a CAD object management system for the design library in VHDL design environment. For the efficient manipulation of design objects, the library is managed independently of the underlaid CAD system. Management and revision of design objects can be performed by a batch script of server commands or through the user interaction in the X/MOTIF graphic environment. Through the library server, design management tasks can be efficiently performed, such as configuration of design objects, version control, and management of attributes and methods for versions. Experimental results show that the proposed system is a viable tool for the management of design data in VHDL design environment.

To facilitate presentations of various media and transfer their implicit meaning efficiently, needed are effective development techniques for representing and manipulation temporal and spatial informations between multimedia data. Especially, these emporal and spatial informationsl are so deeply related with each other that it is required to have the integrated mehod for their representation. This paper suggests the Presentation Synchronization Trdd(PST) which represents their temporal and spatial informationsl and the efficient presentation model as traversing this PST. In this model, without knowing the specific user's interface or any script languages, the user can write the presentation scenario only based on allen's tecporal specification. This model has a characteristic of allowing user's inputs that may dynamically modify the presentation sequence in presentation time. As through the renmining steps of consistency checking for their relations. PST generation, and PST traversing step, this model provides users with simple and effective presentation of multimedial data by having them be presented auton\matically.
