One of the important restraint conditions for determination of rotary tiller parameters is whether the outside of front cutting surface on blade in rotary tiller pushes untilled soil in operation. By theoretical analysis and graphic verification on computer, no sil-push conditions is put forward and formula for calculating the position angle of its bent line derived, as is convenient for selection of rotary tiller parameters and design and drawing of its blade.

게임이 대중화되고 발전함에 따라 게임을 개발하는 방법 또한 발전하고 있다. 특히 게임엔진은 이제 게임을 개발할 때 필수적인 요소로 등장한다. 게임 엔진이란, 게임을 개발할 때 게임의 하부에서 처리할 수 있는 모든 일을 처리하는 API의 모임이라고 말할 수 있다. 본 논문에서는 구조의 파악이 쉬운 잘 설계된 엔진을 제작하기 위한 방법으로서 클래스 기반의 객체 지향 기법을 이용해 설계하는 방법을 제안한다. 게임엔진에 포함되는 가장 기본적인 그래픽 엔진을 소프트웨어 설계 있어서 현재 가장 강력하고 가장 많이 사용되는 모델링 도구인 UML을 이용해서 학습이 쉽고 구조파악이 쉬운 엔진을 설계한다.

The purposes of this paper are to review the concept and system structure of computer graphics and to discuss the applicability of computer graphics technique as an analysis tool in transportation studies. To do this, several applications of computer graphics used for analyzing and solving transportation system problems were described and illustrated. The results indicate that computer graphics are found to be powerful aids to the analysis and design of transportation systems that typically involve large data bases and several interacting components. The results also indicate that computer graphics can be a powerful tool for aiding planner, decision maker and citizen in making it easier to explain and interpret information through mapping and graphic display.

In this paper, fuzzy-neural network is proposed to identify the Activated Sludge Process(A.S.P) in sewage treatment such as "IF-THEN" type fuzzy rules and using various learning methods and improved complex method, the performance index of the identified model is improved. The proposed FNN has the neural network structure of which the connection weights have particular meanings for obtaining fuzzy inference rules and for tuning membership functions. And based on the identified model, graphic simulator which can analize nonlinear characteristics of A.S.P and generate control strategy for A.S.P is being developed.developed.

In this paper a Korean authoring system is designed to write a CAI courseware in Hangul/English by an author who is a nonprogrammer. It saves nock time in authoring a courseware and maintains high level transplantity among CAI systems. By interfacing ah expert graphic utility, image information can be processed more easily and efficiently. Programming control of the flow of CAI courseware can be ramification and individual learning possible, fitting various demands of learners and learning and learning ability.

This paper represents the computer application techniques of initial and modification machining for dies with 3-dimensional scluptured surfaces. All procedures from die design to die machining and measurement are covered. The component of modelling is data management and modification (extrapolation and smoothing), surface modelling, and nc program preparation. Also this paper introduces the utility for successful and efficient operation of system such as map generation, data communication, tool path verification, contour map generation, graphic processing of extrapolation and smoothing results, and CAD/CAM system interface. Examples are given to illustrate the modelling.

In this paper, the animated simulation system (Anisim) is proposed in order to develope an efficient functional system verification tool. It displays the simulation results of the designed system using graphic animation with various models lot the target system. With simple interface definitions given by the user, Anisim generates interface codes automatically. Users can describe and model the target system with the generated interface codes. Since the simulation engine is implemented in C-language, modeling is very simple and simulation can be performed in real time.

This paper deals with the teletext systems with processing the Hangul which is compatible with the NABTS. The Hangul set was included in the graphic-set repertory of the 7bit in-use table and the synthesis method was used to process the Hangul codes. The Hangul in the Teletext systems by the NABTS is possible to use DRCS method, but the transmission delay problem has occurred in that case. As a result, all the programs within the NABTS format are possible to use without any modifications in this systems.
