The purposes of this study is to investigate the characteristics of historicism in modern fashion and to introduce the appropriate approaching and application method of costume history. As one of the characteristic of Post modernism, historicism is an important theme in modern fashion. In this study, the background and the characteristic of Post modernism is considered and the historicism in the Post modern architecture and literature is studied. Next, through the artworks of Vivienne Westwood and Christian Lacroix who are excellent in the modernization of historical costume, the historicism in modern fashion is studied. The characteristic of historicism in Post modem architecture and literature comes from the nostalgia, aspiration for the past, and recurrence to the nature. It is not the revival of the past but the crossover of the past and the present. The characteristics of historicism in modern fashion are as follows. ·form; style, silhouette, and items that are shown in the historical costume come with the mixture of modem textile, new technique, and modem design. ·Materials and patterns; classical and romantic patterns, the artwork of the artist, and the fabric which is remake of remains are used. ·Technique; Tailoring techniques and the pattern making of the historical costume are used. ·Trimmings and etc.; Lots of handworks, trimmings and accessaries in that are inspired from the past are used. These elements are not come from a certain place and time but mixed surpassing places and times. With that, not only the form and the position of wearing but the meaning and purpose of wearing are changed.

Most of the developed countries and Korea have continued to invest much money in developing low-carbon vehicles such as electric car, methanol car and hydrogen car to replace the conventional fossil fuel vehicles. Government and local governments of each country, however, grope to construct roads for bicycle and public bicycle rental systems because bicycle is the only ultimate and feasible non-pollution transportation. Most of the current bicycle monitoring systems have achieved automation of rental process in bicycle stations, but they can not monitor bicycles in use. This paper develops GPS-CDMA modem combined terminals and implements a LBS-based bicycle monitoring system using them for public bicycle rental system. The monitoring system collects location information from GPS-CDMA modem combined terminals attached on bicycles and presents the moving tracks of bicycles on a GIS map for easy return and redistribution of bicycles. Also, the system helps to prevent from theft and vandalism of bicycles and to recommend the nearest bicycle station.

In this paper, an efficient algorithm and area-efficient hardware architecture have been proposed for $2{\times}2$ MIMO-OFDM based WLAN baseband modem with two transmit and two receive antennas. To enhance the performance of the receiver, the efficient timing synchronization algorithm and symbol detector based on MML algorithm are presented. Also, by sharing the hardware block with multi-stage pipeline structure and using the complex multiplier based on polar-coordinate, the complexity of the proposed architecture is dramatically decreased. The proposed area-efficient hardware design was designed in hardware description language (HDL) and synthesized to gate-level circuits using 0.13um CMOS standard cell library. As a result, the complexity of the proposed modem receiver is reduced by 56% over the conventional architecture.

We proposed several systems for 1Giga bit Modem. The first, Binary ASK(Amplitude Shift Keying) system has a high speed shutter transmitter and no IF(Intermediate Frequency) receiver only by symbol synchronization. The advantage of proposed system is that circuitry is very simple without IF process. The disadvantage of proposed system are that line spectrum occurs interference to other channels, and enhancement to 4-level system is impossible due to its large SNR degradation. The second, Binary phase modulation system has a high speed shutter transmitter and IF-VCO(IF-Voltage Controlled Oscillator) control by base-band phase rotation. Polarity of shutter window is changed by the binary data. The window should be narrow same as above ASK. The advantage of proposed system is which error rate performance is superior. The disadvantage of proposed system are that Circuitry is more complex, narrow pull-in range of receiver caused by VCO and spectrum divergence by the non-linear amplifier. The third, 4-QAM(Quadrature Amplitude Modulation)system has a nyquist pulse transmitter and IF-VCO control by symbol clock. The advantage of proposed system are that signal frequency band is a half of 1GHz, reliable pull-in of VCO and possibility of double speed transmission(2Gbps) by keeping 1GHz frequency-band. The disadvantage of proposed system are that circuit complexity of pulse shaping and spectrum divergence by the non-linear amplifier.

High Tech Design manner is a design concept that had been constantly discussed in constitution process of the West art history and modem ideology and had been experimented in industry, having started from futurism and structuralism in the early 20th century through Kinetic Art & Technology Art and up to now. High Tech Design had a great influence also on Post Modernism and more important is that this manner of design will be existing continually in the future too. From the modem times when machine civilization started, the artist and designers expressed a utopia will showing the future world with help of High Tech Design and modem people are realizing technology images as a utopia, in the space and material presented by this high tech design. And this utopia imply the images of dynamic power, speed making a voyage in universe, dream of future, hope, mass production, earth's environment, wealth etc. High Tech furniture was lightly designed by using thin steel wire, structure stressing the metallic characteristic and tempered glass, and it was used for presenting a convenient interior space visually, and with that it can make a unified sense in High Tech interior space, and a contrary effect compared with minimal space. High Tech Design equipped with glass and metal materials looking inappropriate for our interior space due to their sharp and cold image has been regularly used as living furniture, not only decoration function, and then there must be reasons for that. This study intends to research how High Tech Design has been changed and developed in the design history & West art history from the early 20th century, and to present it's value of development as data orienting, namely a direction for the industry of the next-generation and furniture design.

The research purpose of this study, together with the study of Frank Stella's work and his expansion of the formative arts field, is to rediscover "Amabel" and to present a fresh perspective in evaluating and assessing environmental art objects. The results of this study can be summarized as follows. 1. The study investigated the effect how Frank Stella's work affected American modem art trends. 2. The study helped to re-evaluate Stella's work by examining its expansion into the plastic arts. 3. The study analysed the plastic works of Prank Stella and his effect on plastic arts within the modem art trend of America. In conclusion, Frank Stella played a leading role in today's American art style and had a potent influence on the trends of America's modem U. In recent years, his work has had an impacted on the design of parks and art galleries. America's industrial society is led by the growth of economic power and the development of science and technology. In America's architecture and landscape architecture, such new forms as minimalism functionalism, cubism and abstract expressionism, which have been influenced by art movements, emerged in California and the east coast. Influences of Stella such as these are the remedy for a vested stubborn concept of architecture and landscape architecture by introducing a sense of pictorial space in these fields. In landscape architecture, the introduction of art trends appears in several ways. Mainly the trend of Minimalist Art, influenced by Modernism, can be seen in much Landscape Architecture. Frank Stella contributed to the development of such minimalist art.

In this paper, we proposed the reservoir tank wireless integrated management using information filtering for improving the water quality and on-line managing efforts of reservoir tanks. Reservoir tank level sensor works the pump sending the data from reservoir tank control to the wireless control on sensing water level. At this time, every kind data which happens in the water tank transmits the line transmission modem. The data to be received from the line transmission modem is stored at the database after we record the logs by each hour. The proposed method defined the context and environment of the reservoir tank and predicted the profited service according to the pump motion, the solar battery, the chemicals, the water level, the line, and the modem using information filtering. we plan to conduct the proposed method to verify the adequacy and the validity of reservoir tank wireless integrated management using the information filtering.

The purpose of this paper is to examine the change of Korean land transportation system and pattern during 1905-1911 concentrated on road construction so-caued ‘Sinjak-ro’. As conclusions, modem road or ‘Sinjak-ro’ started from modem port to inner hinterland where economic resource or regional center located. A trunk railroad running through Korea Peninsula from Busan to Sinuiju(border between China) is opened its complete operation in 1906 by Japanese investment, when no ‘Sinjak-ro’ road construction begun. Thus from the beginning, railroad station also became important starting point of ‘Sinjak-ro’ as seaports. Before the Japanese annexation of Korea, the ‘Sinjak-ro’ road was constructed mainly between seaport or station, where Japanese commercial settlement located, and hinterlands to help their economic invasion. This study could not deal with other modem transportation systems such as railroads and waterways. It is necessary to examine whole changes of modern transportation systems in this age so that we would comprehend modernization feature of Korea from the viewpoint of transportation history.
