In this paper, the nonlinear damping force model is made to identify the properties of the ER damper using higher order spectrum. The higher order spectral analysis is used to investigate the nonlinear frequency coupling phenomena with the damping force signal according to the sinusoidal excitation of the damper. Also, this paper presents an inverse model of the ER damper, i.e., the model can predict the required voltage so that the ER damper can produce the desired force for the requirement of vibration control of vehicle suspension systems. The inverse model has been constructed by using piecewise linear damping force model. In this paper, the fuzzy logic control based on heuristic knowledge is combined with the skyhook control. And it is simulated for a quarter car model. The acceleration of the sprung mass is included in the premise part of the fuzzy rules to reduce the vertical acceleration RMS value of the sprung mass. Then scaling factors and membership functions are tuned using genetic algorithm to obtain optimal performance.

As we analyzed the formalities of court dress during King Soonjo's rule through the characters depicted in $\boxDr$Wangseja Chulgungdo$\boxUl$(The Painting for a Crown Prince's Outgoing for Schooling to Sungkyunkwan) the results were as follows: People wore their appropriate full dress ac-cording to the ceremonial procedures. In the case of a Crown Prince normally the wore Gongjungchaek(a hat) (after the coming-of-age ceremony Iksunkwan) and Gonryongpo(imperial clothes) to show his status as a Crown Prince. He wore chugkumbok(a Coat) to indicate a Crown Prince as being a student. on an occasion of celebration a Crown Prince wore Wonyugwan and Gangsapo to provide him with prestige and as a sign of respect for the occasion. The teacher of a Crown Prince also wore Gongbok and Sangbok accoding to the dress requirements of the ceremonies. We can confirm that the Gongbok system of all government officials had been main-tained in the late Chosun dynasty. We know that the form of ceremonies be-came simplified in the late Chosun dynasty. it was recorded that students had to wear Chungkumbok. but we knew from the painting that students actually wore Dopo(a traditonal korean coat). We knew through this painting that the court dress rules of the late Chosun dynasty varied that previously known. As we concluded above research on the his-tory of costume by analyzing paintings both supplements our knowledge of the topic and confirms the deficiency in the study of the his-tory of costume based solely upon literature and books.

It is common knowledge that a conventionally woven textile consists of two assemblies of parallel threads (warp and weft), one interlaced with the other at ninety degrees. Where each of the two assemblies is arranged in a particular colour sequence, a check design, known as a 'tartan', may be created. Although similar check-type cloths have been produced worldwide, it is the tartans of Scotland which have received most attention and it is here that a complex set of rules evolved and tartans of different types became associated traditionally with different regions, family groups or 'clans'. There is an impressive array of publications focused on the identification of tartans and their clan associations. This paper explains the nature of tartans, analyses typical surface structures, ratios and proportions, and suggests possible avenues of use for modern designers. The principal sources of data were a collection of tartans held at ULITA - An Archive of International Textiles (University of Leeds, UK) and Stewart's 1974 publication The Setts of Scottish Tartans. Based on the observation that divisions into halfs and thirds were dominant, a series of templates is presented with the intention of developing an awareness among designers that ratios and proportions used in familiar or traditional frameworks can be employed in a modern context.

A lot of expert systems have been developed in the area of medical diagnosis and prescription, but there has been relatively little effort to develop medical expert systems using domestic technologies. In this paper, a medical expert system for gastroenteritis is developed, which can be easily used on the Internet. This system is implemented using Java technologies and Jess, which is a Java expert system shell. Therefore. the system can be used independently from a specific platform on the Internet. In addition, facts and rules of a knowledge base in the system ate represented separately making the system updatable and expandable with ease.

Knowledge of the physical locations of access point of WLAN is becoming increasingly important with the rise of location-based services. In this article, we propose a new AP localization method using neural network approach. Basic theory and properties are derived for precise outdoor AP localization using GPS location information and RSSI. Rules for neural network model are derived and simulation has finally been done to demonstrate the efficiency of the proposed method. The simulation results show that the proposed method can result in AP localization with very. low error probability.

After the twenty-first century, the university emphasize on the role of knowledge creation facilities, and for this, various social and educational requirements are changing the environment of higher education. These change makes university that has old facilities difficult to correspond environmental changes. The purpose of this study is to review the facilities manual of Establishment and Management of university and to suggest amendment of Establishment and Management of university by exploring the university educational environment and facilities plan to respond various changes. We reviewed division of university studies, classification system of facilities, Area Standard of building and site in th provision for university establishment and operation, based on studying domestic university facilities standards, space management standards, facilities condition of national/private university and doing a survey of university facilities satisfaction and propriety of facilities standard in 120 universities. According to this study on validity and propriety of rules, we suggest amendment of Establishment and Management of university that can respond changing higher education environment.

The objectives of this study were to introduce the easiest and most proper applications of datamining in industrial processes. Applying datamining in manufacturing is very different from applying it in marketing. Misapplication of datamining in manufacturing system results in significant problems. Therefore, it is very important to determine the best procedure and technique in advance. In previous studies, related literature has been introduced, but there has not been much description of datamining applications. Research has not often referred to descriptions of particular examples dealing with application problems in manufacturing. In this study, a datamining roadmap was proposed to support datamining applications for industrial processes. The roadmap was classified into three stages, and each stage was categorized into reasonable classes according to the datamining purposed. Each category includes representative techniques for datamining that have been broadly applied over decades. Those techniques differ according to developers and application purposes; however, in this paper, exemplary methods are described. Based on the datamining roadmap, nonexperts can determine procedures and techniques for datamining in their applications.

This study is for analyzing the explosion accidents in the tunnels, roads, subways, streets and various kinds of building construction area with the use of Fault Tree Analysis(FTA). based on the police Department and Guns & Explosives Safety Technology Association's researching materials. the explosion accidents have been investigated and analyzed between 1988 and 1977. As the result, we can find out that the majority of the explosion accidents in Korea is the accidents by flown stones(45.7%), like in Japan. So we make the research chart which is needed for analyzing the explosion accident, and then analyze these accidents systematically. using the investigation codes of the industrial accidents. After that, the FTA was performed on the accidents by flown stones. They result fromm non-observance of the safety rules, and lees knowledge of the safety and so on. Moreover several causes are combined and then the accidents are apt to happen. So according to the results of this study, for the protection of the explosion accidents, the specialized safety education is badly needed and the enough investigation of the places before the work along with the management for safety in working must be planned.

Active Noise control(ANC) is rapidly becoming the most effective way to reduce noises that can otherwise be very difficult and expensive to control. This research presents ANFIS (Adaptive Network Fuzzy Inference System) controller for adaptively noise cancelling in a duct. ANC system generates secondary control sound pressure with same amplitude and with opposite phase as noise to be eliminated. ANFIS controller is trained to optimize its parameters for adaptively cancelling noise. That is ANFIS train its parameters by gradient descent and LSE method so called hybrid method. This paper present ANFIS in active noise control which provides an improvement convergence speed and limitation of linearity condition. It can model nonlinear functions of arbitrary complexity and ANFIS can construct an input-ouput mapping based on both human knowledge in the form of Takagi and Sugeno's fuzzy if-then rules and stipulated input-output data pairs. This paper also shows that the proposed ANFIS active noise control system successfully cancelled noise.
