This paper deals with the design scheme of the custom control circuit for optimizing the interface of peripheral devices to general-purpose controllers for the high speed digital system. When the various peripheral devices such as memory, I/O devices and buffers which operate at low speed are interfaced to the microprocessor which operates at high speed, inserting the proper wait state to the processor is required. The proposed scheme designed with random logic may be applied to the high performance graphic system like the X-terminal. This circuit provides the flexibility and system independancy for the optimum digital system design.

In this paper Vehicle driving simulator have been used in the development and modification of models. A real-time simulation system and washout algorithm for an excavator have been developed for a driving simulator with six degrees of freedom. An interesting question, "how the 6 DOF Driving Simulator can be controlled optimally for the various tasks?" is not easy to be answered. This paper presents the hardware and software developed for a driving simulator of construction vehicle. A simulator can reduce cost and time a variety of driving simulations in the laboratory. Using its 6 DOF Simulator can move in various modes, and perform dexterous tasks. Driving simulators have begun to proliferate in the automotive industry and the associated research community. This effort involves the real-time dynamic of wheel-type excavator the design and manufacturing of the Stewart platform an integrated control system of the platform and three-dimensional graphic modeling of the driving environments.

In this paper, we design and implement complement based speech training system for voice disorder. The system consists of three level of training: precedent training, training for speech apprehension and training for speech enhancement. To analyze speech of voice disorder, we extracted speech features as loudness, amplitude, pitch using digital signal processing technique. Extracted features are converted to graphic interface for visual feedback of speech by the system.

Industrial ventilation is one of crucial engineering measures to protect workers from hazardous airborne contaminants. Designing a ventilation system is not an easy task. To solve this problem, U.S. computer programs and softwares have been developed. In Korea, a software, called as VPMC(Velocity Pressure Method Calculation), was developed by Korean Industrial Safety Corporation. Since VPMC is a DOS-based software, it could not be a user-friendly one. In this study, a Windows-based software was thus developed to overcome the difficulty in using a software for designing the ventilation system. As far as we know, this kind of Windows-based software is the first in the world. But this software should be kept being revised. The future work would include introduction of GUI(Graphic User Interface) and enhancement of editing functions by using Data-Base programs.

The probability of visual perception occurrence varies in case the expectation of using each unit space of which the whole space consists because the size of space subject to analysis is very large or the organization is complicated in the analysis of spatial visual configuration. Therefore, it is necessary to compensate space analysis and index measurement by applying weight to the point of view for the probability of experiencing space. This study proposed a method of analyzing visibility ratio by applying the integration of space syntax theory as weight, and grasped the effect in comparison with the visibility ratio when weight was not applied.

Modern life is surrounded by all kinds of information and screen, motion graphics in these media everywhere, you can use it to a special performance of the method, the use of the stage, so that the effect is more vivid stage performance. Stage design industry began to diversify the use of Motion graphic, have long been out of the framework of the traditional background, turn into dynamic video space. In this paper analysis of research papers by the dynamic changes in the graphics arena background, style, affect the application of dynamic images. Summed up in the stage of development that can adapt to the requirements of the times, better performance stage effects and express emotion of the stage performances.

Minimalism combines the adjective 'minimal' and the suffix 'ism', and was first coined in the 1960s. Minimalism draws on the belief that when the use of artistic skills and adaptation is minimized and only the essentials or core is expressed, the discrepancy or distance between reality and art can be kept to a minimum; and thus, true reality can be achieved. To realize minimalism, artists creating paintings, sculptures and other forms of visual art eliminate unnecessary elements and strip objects to its essentials. And hence, most minimalist artwork used minimum amount of color and focused on expressing the geometric essence of objects. Such simplistic styles of minimalism can be seen today in various designs. Apple's iPod design and other product designs as well as graphic designs are just few of the examples. Drawing on the spirit of minimalism, Icongraphics pursues beauty and pleasure in the minimal use of color and form. And what lies beneath Icongraphics' artistic style is its pursuit of simplistic essentials, sending a strong message to the digitalized and complex lives of modern people.

The above-Knee Prosthesis has been used by the handicapped person and become a important part of their life. But uniform above-knee prosthesis only increases inconvenience And so the tool that can estimate and help to design of suitable prosthesis for user need to be developed. The simulator developed in this research is composed of two part. One is hardware that can realize various walking motions. The other is software that can display and analyze the results of walking mot ion. Three motors constitute hardware of Simulator. Two motors are used to realize heap motion that need two degree of freedom and the rest one used to realize swing motion. Software of Simulator display results of three motor trajectories and walking mot ion of hardware using computer graphic. Therefore, The simulator developed in this research which is able to realize human gait and results are analyzed through simulation program at PC will be some help to design and produce of prosthesis suitable to user.

Software architecture serves as a framework for understanding system component and their interrelationships. Software architectures can be reusable assets to achieve low costs, high productivity, and consistent quality. We have developed a software architecture design environment, called Happy Work. In this paper, we would like to present the structure and functions of Happy Work. Happy Work has two main functions. First, it provides a graphic editor for modeling of software architecture diagram. Second, it provides an ADL, called HWL(HappyWork language). HWL is a language that describes software architecture.

The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).
