Developed in this paper is a feature based modeling system for the design of welded plat construction(WPC) which is composed of flat or bended plates represented as reference plane with a constant thickness. First, the necessity and the characteristics of the modeing system for WPC as compared with the assembly of mechanical parts are investigated. Secondly, feature library for the assembly of WPC is shown which contains several types of features like joint feature, groove feature, material feature, and precision feature. Thirdly, the assembly procedures are presented which mainly consist of both the assembly transformation and the correct assembly checking. Fourthly, weld lines of the assembled WPC are defined so that those can be used in the process planning or the manufacturing stage. Finally, a prototype by a geometric modeling software Pro/Engineer, a graphic software GL(Graphic Library), and C language on a CAD workstation IRIS.

Recently, as the form of media has been various and computer graphic technology has developed, it has been possible and attempted to present database information 3-dimensionally and dynamically. However, there was not many studies done regarding how to present 3-dimensional and dynamic information. Therefore, this study was conducted to develop presentation techniques and languages of 3-dimensional and dynamic information. This paper consists of four section. First, it was introduced by secondary research that fundamental knowledge and functions for presenting the information by the computer graphics. In other words, it was stated what is possible to present 3-dimensional information on the 2-dimensional screen and which functins becomes better as computer graphic technology has developed. Second, computer graphic model that present database information should also have hierarchical structure that database information has. Thus, it was discussed how to present information regarding how to make a structure of graphic model that present database information. There are two ways to present information- by changing structure of information and by changing graphical presentation techniques. Third, all the graphical presentation language was collected and explained. Finally, the case study of presenting statistical data for baseball players demonstrated concrete example of using graphical presentation language.

Svg(Scalable Vector Graphics) is xml graphic standard recommended by E3C as a language based on xml to express two-dimension graphic. Svg can accommodate all Xml's patency and advantage of interoperability, and can used as various web applications being combined with other xml language. In addition, Svg can be applied to the fields of electronic commerce, geographical information, computer education and advertisement because it can produce high quality of dynamic from real-time data. SVG's application can be enhanced by linking with database. In this paper, we discuss how Svg can be utilized in theater reservation system, not just explaining svg's meaning or ability. Svg added graphic advantage in addition to xml's advantage. This means that svg retains not only graphic element but also xml's softness. It becomes easier to designate seats and add them. Current reservation system provided in general only information on time and price for a ticket, but the system using SVG in this paper provides additional information on position, price, cancellation and purchase availability of seat.

In this paper, we Present the implementation of statistical process control software by using XLISP-STAT which is a kind of object oriented language under Windows environment. This software can be used to generate the graphic objects for various control charts, histogram and plots using the full-down menu system. This software can also be used to calculate control limits, process capability indices and test procedures for normality.

This paper presents an algorithmic approach used in the development of a task-level off-line programming system for the efficient applicaiton of robot. In the method, robot tasks are graphically described with manipulation functions. By applying robot language these graphic robot tasks are converted into commands for the robot. A programming example demonstrates the potentiality of task-oriented robot programming.

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.

In this paper, graphical representations of parameter variations affected by series or parallel feedback in the load plane were studied. As a result of transformations, all parameters of 2-port was converted to circles, and the step of noise circles and gain circles was 0.1 dB and 1dB, respectively. Compared with conventional commercial CAD softwares, the circuit design procedures could be verified much more systemically. This CAD was programmed in C-language and executed in IBM-PC with VGA graphic adaptor.

The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

We developed a low cost digital X-Ray image capturing system using a CCD camera, instead of using the high cost image plate and image intensifier. In order to reduce the system volume, we directly made the dark box shorter than the previous model. Using the graphic language, we developed a program in order for post-processing the images captured by the CCD camera. This program improves the image resolving power.
