We see that the Interactive Entertainment Industry on the internet has a great potential to grow in the 21st century. There will be many kinds of internet content. Internet contents can be classified with six categories such as identity, entertainment, learning, shopping, community. However, we see that shopping and community have a higher market share among the six. Recently, community has become more important in making an internet business sucessful, because it is valuable in creating virtual society in cyber space. A chatting program has been an effective means to form community. So we developed the animation graphic chatting program that functions to express an emotion effectively compared to the text chatting.

This paper describes a development of conversational program for lathe. The proposed program is a NC programming system specialized for use in machine tool controls. Its easy to use graphic interface built-in database capabilities make it an ideal way to program part on the shop floor. In order to manage effectively machining process it proposed the algorithm of tree structures for design processing. Also using interative structure it proposed the methods of conversational programming to generate automatically NC program.

A pre-processing program based on the OOP(object-oriented programming) concept has been developed. The program consists of the input of a 2D or 3D flow problem to a CFD program by means of an user-friendly interface and the subsequent transformation of this input into a form suitable for the solver(PowerCFD) using unstructured cell-centered method. User-friendly GUI(graphic user interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions of this program are introduced and demonstrated, which include mesh generation, boundary settings, solver settings, generation of grid connectivity and geometric data etc.

Nowadays the use of computer has a tendency to be being increased in classroom. Also, Many mathematics teachers are attempting to use computer efficiently in classroom. Computer has unique functions such as graphic, animation, and error correction. As graphic and animation can make the content of mathematics visible and make it easy for learners to study mathematics, it is desirable to develop the computer educational program and use it in teaching and learning mathematics. Especially, before concepts study on the unit of Figure or Function, the use of graphic or animation is efficient by being able to understand easily the content. The purpose of this thesis is to produce the computer program on the Movement of Figure in the unit of Equation of Figure which is in mathematics curriculum for the first grade of high school. In teaching and learning mathematics by use of this program, the educational effects are expected as follows: 1. It is expected that this program will stimulate the interest of learners by using animation and acoustic (sound) effect and so learners' voluntary and active thinking activity will be shown. 2. It will be helpful to form exact concept because it is possible to understand intuitively the basic concepts on the Movement of Figure by using graphic and animation. 3. It is expected that the repeated study of this program already designed will remove the fear of incomplete parts and help review them. 4. It is possible to change from teacher-centered instruction, which is the blind point of recent mathematics education, to the learner-centered instruction. However, it is necessary to realize that using the educational engineering (computer) in mathematics education cannot always cause learners to study mathematics very well and that computer cannot take the place of mathematics teacher. Accordingly, computer will be treated as aids which help learners study difficult part.

Although the use of NC machine is increasing in modern industry, unfamiliarities of the NC program syntax do not allow us to program it easily. So, automatic programming systems, such as APT, COMPACT, CL, were developed to help the uninitiated to write NC program easily. In this research, Korean Automatic Programming System for 2-axis NC lathe is developed, by which NC program is easily programmed using Korean letters. In addition, Graphic Debugger for 2-axis NC lathe is developed for debugging the NC program error and animating the cutting process. The above systems are run on the IBM-PC/XT.

In this paper, we developed a Windows 95 version Off-Line Programming System which can simulate a Robot model in 3D Graphic space. 4 axes SCARA Robot (especially FARA SM5)was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the OLP system in the Windows 95's GUI environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D Graphics.

In a specialized modern society and/or visual communication technique seems to be preferable to the traditional one-way communication technique which resorts to reading materials. P.R materials currently produced by various levels of Korean government administrative bodies seem to outdated and inefficient both in their contents and in graphic technique employed. In this paper we argue that the problems of the communication technique used by Korean government result mainly from the ambiguous nature of the message of P.R materials and the inability to differentiate the contents of P.R materials according to the target audience. We recommend various changes to the current government communication program and emphasize the importance of graphic communication technique for the production of more effective and professional communication materials

Even if some kinds of software for halftoning such as raster image process program are on the market, most of them couldn`t apply to the new laser gravure cylinder making machine because they are closed the source program. In order to develop new laser gravure engraving machine, we were investigated new suitable halftoning software based on the mapping and equal density expansion algorithm that we are mapped. As the results of actual practice with Microsoft Visiul C++2.0 in 133Khz 64M ram IBM personal computer, we found that the new software for halftone generation for laser gravure engraving machine are available in new machine, and easily load and processing the graphic image for gravure hardcopy.

In this paper it is discussed about the program which makes automatically the preprocessing data on the graphic editor of PC monitor. Three kinds of colors are used in order to make know a boundary_element, in_element, out_element. By initial mesh generation, three kinds of elements are made; the element with three nodes, four nodes, five nodes. The node of boundary element draw a vertical line to the boundary. At that time the element with three nodes is removed and the element with four nodes is changed to the element with four nodes. The domain graphic on this paper is compose of piecewise curves which has many lines and a hole. The data of element is written on the memory of PC computer. The program controls the memory address according to the change of element's quantity; disappearance and addition of element. All this work is operated on the PC computer.

SPC is the quality improvement technique of gathering since Motorola of U.S.A. have used SPC technique as a statistical process control method for promoting 6-sigma quality improvement strategy in 1988. In Korea, small and medium-sized enterprises are needed building of a system for statistical production control . In the present study, the methods of building SPC system with a moderate cost using a graphic programs of easy-to-use and high flexibility for small and medium-sized enterprises were inquired. The SPC system which enables statistic marking (maximum, minimum, mean, standard deviation, process capability index) and graph marking (X-Y coordinates and histogram) using LabVIEW 5.0, the graphic program by National Instrument Co., Ltd. was implemented in this study.
