This paper prosed modelling and design method in suspension system sesign to analyze sky hook damper system by adopting active suspension control theory. Recent in the field of suspension system design it is general to adopt active control scheme for stiffness and damping, and connection with other vehicle stability control equipment is also intricate, it is required for control system scheme to design more robust, higher response and precision control equipment. It is hon that sky hook suspension system is better than passive spring-damper system in designing suspension equipment. We analyze location of damper in sky hook system and its motion equation then design robust control system. Numerical example is shown for validity of robust control system design in active sky hook suspension system.

In order to understand the concepts of image processing with effect, a learning system with an actual practice is necessary. As most image processing learning materials have some inconvenient respects that it is difficult to understand the processing procedure because they simply show the processed results as figures in the contents, and also, a separate practice tool is needed to operate the source codes because they provide the program source codes as a part in the context. In this paper, in order to solve above inconvenient respects, an image processing learning system that be able to improve the learning effects as accomplishing the theory studying and the actual practice in parallel is proposed. As this system is composed on the bases of java, it is independent to the platforms and it is possible to implement on the Web.

This paper describes technical details of Separate Excitation Inverter(SEI) application for the photovoltaic system. Depending on the output characteristics of solar cell modules, optimum control for the maximum electricity generation of photovoltaic system could be determined. New control mechanism of Separate Excitation Inverter for the Photovoltaic-Diesel Hybrid Generator was tested and examined. Results of this paper describe that maximum out of solar cell array could be obtained at two points. Therefore the two point control method was applied and verified between, the theory and the experiment.

The main purpose of this study is the comprehensive review of the compensation system that affects the employee's job satisfaction and turnover intention. This study is mainly designed to review previous studies of the impact of compensation system, and suggest meaningful implications in relation to firm's performance. It is clarified that compensation is positively related to firm's performance, and the perceived equity mediates the relationship between compensation and performance. It is suggested that an empirical research should be done based on the formulated propositions of this research.

Engine mounting system is the most responsible system for NVH performance of vehicle. The vibration at idle shake, road shake, Key ON/OFF, gear shift tuned by the engine mount position and stiffness. Previously described Engine mounting system theory investigated and summarized in this paper. Decoupling of the Power train rigid mode and Reducing the angle between Torque-Roll-Axis and Elastic-roll-Axis is starting point of optimization. Multi-optimization analysis was performed because of variety simulation case and FE-model. Eventually, Find the best mount location and the stiffness has improved the performance of the vehicle NVH.

We developed the decision support system by using the fuzzy theory. This system designs harmonious color space according to the linguistic input. This input represents the atmosphere which the user want. If the linguistic input of adjective image scale is given in the developed system, the relation between the adjective and color is supposed as fuzzy relation. The color which match with the whole atmosphere of color space is selected. The search region of harmonious color decision is controlled by the knowledge on color harmony of Moon-Spencer. Harmonious color is selected by it.
