Trompe l'Oeil technique strategically conceived with a view to effectively realize creative ideas among the expression techniques of fine arts style has provided the driving force in development of fine arts and has continuously influenced development of the modem fashion pursuing unique individuality. The study is focused first on finding out how Trompe l'Oeil technique originated in connection with researching the fashion of Trompe l'Oeil and on analysing the technique of expression. The author referred to fashion magazines for designing ideas of Trompe l'Oeil represented in modem fashion in practical applications used by designers in Paris, Italy, London and New York during the 10 year period(1990-1999). The collections of data were analyzed as following: Effectiveness depending on the method of Trompe l'Oeil I. Effectiveness of Layering: when two clothing are over lapped or coordinated with one another in color or style. 2. Effectiveness of Detailing: when pictures, stitch, tape, cutting, quilting and etc are used to create collar, pocket, yoke, zipper, string, shadow and etc. 3. Effectiveness of Accessories: when the image of necklace, belt, tie, tassel, badges and stars are represented by illustration or embroidery on clothing to substitute the actual existence. 4. Effectiveness of Nudity: when human body is realistically drawn and printed on clothing.

Sportism is continuously expressed in every season in a different theme and established as a Mega-Trend of the early 21 th century fashion. This study was conducted to research the social and cultural sources of the sportism expressed in the early 21th century fashion. This study focused on hybrid as one of the post-modem phenomena. By analysing social and cultural sources of the sportism, three aspects were found; first, many different fashion trends are coincides in post-modem society, which is possible and accelerated by hybrid each other. Second, the complicated and competitive society urge the people to review the past and the originality. Third, youth-oriented and individualistic lifestyle was brought by the development of the technology and economic surplus. Hybrid of the TPO was analysed which made the sportism mega-trend. 'Formal wear was mixed with casual wear, casual wear with active sportswear, hi-fashion with street fashion, and hi-fashion influenced formal and casual wear again'. The sportism prevalent in 21th century fashion can be explained by this system of hybrid. Results of the analysis in this study can be categorized into four aesthetic values based on hybrid of the styles, which are glamorous sportism, romantic sportism, minimal sportism, and heritage sportism.

교통관제시스템을 구축하려면 이동체들의 실시간 위치데이터를 제공할 수 있는 GPS-MDT(Mobile Data Terminal 이동데이터단말기)와 이동체들의 위치데이터를 수신하여 GIS 상에 위치를 표시할 수 있는 교통 관제용 SW가 필요하다. 이동체의 위치데이터를 VHF 송수신기를 이용하여 전송하기 위해서는 GPS 정보를 취득하고 데이터를 전송하기 위한 모뎀이 필요하며, 관제실에는 GIS기반 이동체들의 교통상황을 모니터링하는 프로그램을 개발하여야 한다. 이동체들과 관제실 간에서 자동으로 이동체의 ID를 포함하여 GPS의 시각 및 위치정보를 지속적으로 전송하여 취득할 수 있는 통신프로토콜도 연구되어야 한다. 본 논문에서는 음성과 문자정보를 동시에 전송할 수 있는 VHF 송수신기용 모뎀과 GIS-tool을 이용한 관제용 S/W에 대하여 연구하였다.

The purpose of this study is to know outer and inner characteristics of Bobos style regarded the latest fashion and to estimate the characteristics of fashion trend in 21st century and direction of fashion in the future, In terms of contentions of this study, we firstly studied concept, background, general characteristics which had been introduced in Sociology. And then, we studied the effect which the style of Bobos had been given by investigating the concept and style of Hippies and Yuppies. Also, we analysed trend of Bobos represented in modem fashion and tried to examine outer and inner features of Bobos through the result of analysis. Bobos can defined as 'Bourgeois Bohemian' who have both mundane desire about success and are high-educated elite class in information-oriented society. The fashion styles which had affected Bobos were psychedelic, naturalism, unisex, ethnic, layered, grunge of Hippies in 1960s and traditional, power-look, contemporary-look, sports wear, casual wear of Yuppies in 1980s. As a result of examining features of Bobos style, we can know that outer feature of Bobos style showed a reasonable harmony regardless of formalities and inner features showed a tendency to seek comforts. Also, Bobos style showed various and free styles, textile materials and colors and complex features to transcend the time and region, and culture.

Since the idea of registering architectural heritage from the early 20th century was introduced as part of the code in the Cultural Heritage Protection Law in July, 2001, more systematic and flexible application the code has been in great demand. It is the aim of this thesis that we preserve modern buildings and then use this research data what find our modern history. So we should find connection of modem and tradition with the overcome of the feeling of being victimized. Accordingly, based on preservation cases and finding of modern house heritage, it is the aim of this thesis that we find the way of the best use. The purpose of this research is to establish a more comprehensive and commonsensical guideline for the preservation of modern architecture satisfying both the government and the registering party, based on more thorough architectural analysis of residential edifices. The results of this study were as follows: (1) It is necessary for application and conservation by point, area and network method. (2) It is needed that periodically check and record central system for the purpose of the management of those. (3) It's consider that develop of conservation method on co-ownership with citizen by house personality.

In recent years, it has been a worldwide trend that many power utilities gave their attention to develop and operate their power plants, substation and distribution systems. Following this trend, KEPCO(Korea Electric Power Corporation) has developed many electric automation systems with various communication networks. It has been natural that the automation systems are just focused on to remote devices when they come to be designed. But, we have to shirt the focus to the automation system itself. There are many problems in maintenance and integration of the automation systems. When an automation system can't control some remote devices, there is no way to get why and which part(Master, Network, Master-side Modem or Remote-side modem, Remote Device, etc.) of the system has problems. Moreover the system just directly links to another automation system. If the system has to link many systems, it needs the linker per each systems. So, we need a new concept to resolve that problems, and develop the Intelligent and Integrated Gateway(IIG) for the automation systems for easy maintenance and integration.

Relaxed static stability(RSS) concept has been applied to improve aerodynamic performance of modem version supersonic jet fighter aircraft. Therefore, flight control system are necessary to stabilize an unstable aircraft and provides adequate handling qualities. Also, flight control systems of modem version aircraft employ a safety system to support emergency situations such as a pilot unknown attitude flight conditions of an aircraft in night flight-testing. This situation is dangerous because the aircraft can lose if the pilot not take recognizance of situation. Therefore, automatic recovery system is necessary. The system called the "Pilot Activated Recovery System" or PARS, provided a pilot initiated automatic maneuver capable of an aircraft recoveries in situations of unusual attitudes. This paper addresses the concept of PARS and designed using nonlinear control law design process based on model of supersonic jet trainer. And, this control law is verified by nonlinear analysis and real-time pilot evaluation using in-house software. The result of evaluation reveals that the PARS support recovery of an aircraft unusual attitude and improve a safety of an aircraft.
