In this paper, a high throughput multiple transform architecture for H.264 Fidelity Range Extensions (FRExt) is proposed. New techniques are adopted which (1) regularize the $8{\times}8$ integer forward and inverse DCT transform matrices, (2) divide them into four $4{\times}4$ sub-matrices so that simple fast butterfly algorithm can be used, (3) because of the similarity of the sub-matrices, mixed butterflies are proposed that all the sub-matrices of $8{\times}8$ and matrices of $4{\times}4$ forward DCT (FDCT), inverse DCT (IDCT) and Hadamard transform can be merged together. Based on these techniques, a hardware architecture is realized which can achieve throughput of 1.488Gpixel/s when processing either $4{\times}4\;or\;8{\times}8$ transform. With such high throughput, the design can satisfy the critical requirement of the real-time multi-transform processing of High Definition (HD) applications such as High Definition DVD (HD-DVD) ($1920{\times}1080@60Hz$) in H.264/AVC FRExt. This work has been synthesized using Rohm 0.18um library. The design can work on a frequency of 93MHz and throughput of 1.488Gpixel/s with a cost of 56440 gates.

This study focuses on the hats in the advertisements of the newspapers from the Greater Korean Empire to the Time of Independence. There were Yeomo(禮帽), Jungsanmoja(中山帽子), Jungjeolmoja(中折帽子), Women's hat, Undongmoja(運動帽子), and Hakdomoja(學徒帽子) from 1897 to the 1900s. The names of the hats were written with Chinese characters as there was no specific name for women's hats. There were a lot of hats in the 1910s; Jungjeolmoja, Jungsanmoja, Hukyeomoja(黑禮帽子), Panama, Doriuchi(鳥打;とり-うち), Maggomo(麥程帽), Ilkyomoja(一交字帽), cheongyeonmo(靑年帽), Jajacheongyeonmo(刺子靑年帽), Hakaaksangmo(學生帽), Undongmo, Laparyunmoja, Banghanmo(防寒帽), Mokchulmo(目出帽), Pungbangi(風防耳), Nambaui, and Pungdongi(風憧耳). Most of the hats were western hats for men. From the 1920s to 1930s, the hats were classified as to the shape and uses as compared to before that period. The hats were advertised in the newspapers such as Jungjeolmoja, Jungsanmoja, Panama, Doriuchimo, Maggomo, Ilkyomoja, cheongyeonmo, Jajacheongyeonmo, Hakaaksangmo, Undongmo, Banghanmo, Mokchulmo(目出帽), Adongmokchulmo(兒童目出帽), Pungdongi, and Pungchasamsangun(風遮三山巾). There is little information about hats from the late 1930s to the time of independence because of the censorship of the press. The hats during that period were almost the same as the before that time. There was a new name of a cap, Jeontumoja(戰鬪帽子) which was for a soldier. The hats in that period were one of the westernized items with shoes before the westernization of the Korean costume under Japanese imperialism. Furthermore, the western hats could be spread by the men who were in the center of the society. On the other hand, women's western hats were not common because women had rarely worn them before that period. They just wore traditional winter caps steadily.

As modern society advances, women's self-consciousness and attitudes toward beautiful appearances have changed. Amid this trend, the young and slim body of adolescent girls expressed in contemporary fashion incites fantasy on continuing youth among women. In modern society, women's youth is frequently regarded as a subject of consumption and a sex product in the mass media. In this regard, the study is focused on examining desire and psychology of worshipping women's youth and beauty in connection with flapper fashion in the 1920s. In the process, the study took a look at the social and cultural background of flapper fashion and conducted an analysis on formative characteristics and aesthetic sense of flapper fashion as follows: First, the formative characteristics include a short skirt that expresses straight lined shape and the beauty of exposure, lighter clothing, thick make-up, short hair style and black or vivid colors, and they lead to exceptional and innovative aesthetic sense in flapper fashion. Flapper fashion style is focused on completely denying outdated fashion worn by women in the age right before. Second, pursuit of mature, graceful and classical beauty that had continued in previous ages has gone through complete changes in the flapper era in the name of pursuit of youth, and the flapper fashion expresses sensual image through the exposure of slim arms and legs of a young girl. In the formative characteristics, aesthetic sense of youth and sensuality inherent in the flapper fashion was generated. Third, women's free-spirited lifestyle at that time and 'aesthetic sense of freedom and amusement that reflected the speed of machine civilization could be found in the flapper fashion. Material and decoration of the flapper fashion pertained to clothing that enabled a free expression through rapid movements. Aesthetic sense of the flapper fashion generated in the process could be defined as women's internal determination to express individual and free-spirited ideas through the use of fashion when tradition and order of the old age were torn down. And this aesthetic sense is continuously affecting modern fashion design.

All the text of housing in 1910s was conveyed in three; hygiene general readings, home economics texts saying women's responsibility of cleaning house, and Japanese's observation and criticizing Korean housing. It stressed sanitary conditions of housing and criticised Korean housing dirty, of which contents and logic were same with the housing discourse in 1900s but much simpler and smaller in amount. It was mainly written by those in medical treatment field like doctors for enlightenment of private hygiene practice to Koreans. Because Choson Government-General(朝鮮總督府) excluded Korean residental areas from urban sanitation project, they remained dirty in 1910s. The practice of housing sanitation remained just as a matter of private sanitary practice. These political and discoursive conditions insinuated a sense that Korean dirty housing was representation of Korean's uncivilized customs and manners and a reason for being colonized. This sense made many Koreans to insist their housings' reforming to sanitary states just for civilization during colonized period.

The series of ‘Dubonnet’poster is one of the masterpieces of Cassandre who was the leader of advertising poster in 1920's and 1930's. Orihinally it was a triptych, but it was developed as a serial work later through lettering and seasonal advertising posters. It was kept in circulation for more than two decades and issued in a variety of formats. In this thesis I tried to figure out the artistic character and uniqueness of Cassandre's poster by analyzing it with many different points of view of the poster, the stream of changing style and influence from the Avant-garde painting. In chapterII, objectively analyzing the series of‘Dubonnet’one by one, I examined the method that Cassandre used to deliver the concept of advertising and his message. The triptych, the first one of series of Dubonnet poster is witty, the slogan is a pun using the words dubo(doubt), bon(good), and Dubonnet, and the theme is treated as an animated sequence in the manner of a comic strip. In the following winter and summer seasonal advertising posters, the‘Dubonnet man’in the same position is enjoying the‘Dubonnet’, irrespective of the hazards of climate and season, There was a change towards 1929 that rectilinear design gave place to supple and undulating lines in Cassandre's posters. Seasonal advertising posters also showed the change, and the tendency of realistic and concrete elements of an expression was strengthened. In chapterIII, I studied three as main characters of Cassandre's poster. The first one is simple and geometric expression, second one is uniqueness of figures and the last one is important roll of lettering. Cassandre believed that there were fundamental differences between the function of a poster and that of a painting. He also recognized that the symbol was the essential element in the poster design, which would be simply and swiftly recognized. The recognition led him to simple design and bold geometric abstraction. He was a man who knew the value of copy in advertising and developed it fully in his simplified geometric compositions by integrating of letterforms and image. The‘Dubonnet man’is geometrized, almost featureless. This approach of rendering human beings was one that Cassandre had used from the early years, most notably in his posters for Dubonnet.

The purpose of this study is firstly to survey the social and cultural background of 20th century and women's status, and to identify what the ideal body is like and what the elements of outer garment and underwear are and the techniques to incarnate the ideal beauty. Various papers are referenced for theoretical study and the elements and techniques of underwear are analyzed based on photographical materials. This paper concludes as follows. In 1910's, ideal beauty has changed to H-style. In other words, the outer garment has confined the lower part of the body with plain H-type Hobble silhouette to express plump bust, somewhat slim waist, and small hips, As the underwears, cylindrical corsets which fasten from under the bust down to lap, brassiere which are helpful for plump bust, and artificial busts were worn. In 1920's, outer garment were Straight box silhouette style which were cut as tubular without dart, and the underwears were corselets which have been tubular from the bust to hip and the tubular chemi-knickers. The former corsets which had been hard-boned and been fastened with strings have been replaced by the hook closure due to the development of elastic joining method. In 1930's, women pursued perfect body showing the line of bust, waist, and hip. In order to express elegant beauty of female of Slim and long silhouette, Doter and underwear have been cut with bias and gore, and soft and flexible materials were flowed along the body. World war II in 1940's has made the women as social. Ideal beauty has changed to Short straight box silhouette which no more shows body line. Outer and underwears were simple and Practical style. In 1950's, ideal beauty was well-matured, elegant Women which were represented by round shoulder, conical breast, tiny waist and round hip. Outer garment showed Hourglass silhouette representing the body-tight suits with round shoulder pad and the wide flare skirts. As the underwears, conical brassiere by top circular stitch were preferred for plump and bulged bust and tight corsets for tiny waist and magnificent petticoats were worn.

This study purposes to examine the background of the sexual concept and femininity, masculinity and gender role in the fields of social psychology and cultural anthropology and investigate the traditional gender role and the fashion's changes according to its role and the examples of the masculinity and femininity expressed in the contemporary fashion and finally analyze the gender identity expressed in fashion. The image changes which appeared in the modern fashion can be considered to be Masculine Look, Garconne Look, Feminine Look, Unisex Look, Androgynous Look and Genderless Look. The Garconne Look caused lots of changes to masculinity in the 1920's along with the changes of femininity. With the effect of feminism, many females wore clothing which had been thought as male's clothing by the appearance of Masculine Look. The major formation reason of Unisex Look can be regarded as the attitude change of the society toward to females and a meaning which doesn't want the differences of the distinction of gender to appear any longer as a characteristic external factor is implied. Androgynous Look which appeared in the 1980's means the integration of femininity and masculinity which is the same meaning with 'androgyny' in itself, Not denying its gender characteristics individually, the Androgynous Look means that women aim at the masculine image in men's clothing or men do at the feminine image in women's clothing. Genderless Look can be considered to a look with a notion to wear clothing freely even in fashion transcending the border of masculinity and femininity differentiated socially and culturally.

This study is an analysis of the life of Max Planck (1858-1947), the in view of engineering literacy education. Some expressions describing Planck include "the father of German science", "the namer of Quantum". Furthermore, he is the scientist who permanently engraved his name in a scientific invariant called the Planck Constant. Planck had already made remarkable scientific achievements in his mid-ages, which became the springboard of quantum mechanics, but he went on to achieve much more in his old age. Between 1910s and 1930s, he was the director of the Kaiser-Wilhelm Gesellschaft, the Berlin Academy, and the German Physics Society, which is the German core research group. In the 1910s, he endured the terrible personal suffering of losing his three children and then succeeded in rebuilding German science in the 1920s in his golden age of 70s. His achievement was great not only as a scientist but also as a science administrator. His life was contradictory in several ways. While fundamentally being a conservative, he initiated a great scientific revolution. While making efforts to preserve traditional values, he was in the center of great many upheavals and destruction. While being the incarnation of honesty, he was also given to extremely delicate political positions. In his long career, Planck lived with all his might as a leader of the German science organizations and permanently left his name on the institute representing Germany. Planck succeeded in his work for the institutional development of science, philosophical understanding of science, and as a role model of exemplary scientist. His long life was accompanied by both achievements and failures, intangible and difficult to judge. Today, as research and development management and scientific leadership have become increasingly important, Planck's life may be a good example of engineering literacy education.

A transformer is a device that changes the current and voltage by electricity induced between coil and core steel, and it is composed of metals and insulating materials. In the core of the transformer, the thermal load is generated by electric loss and the high temperature can make the break of insulating. So we must cool down the temperature of transformer by external radiators. According to cooling fan's usage, there are two cooling types, OA(Oil Natural Air Natural) and FA(Oil Natural Air Forced). For this study, we used Fluent 6.2 and analyzed the cooling characteristic of radiator. we calculated 1-fin of detail modeling that is similar to honeycomb structure and multi-fin(18-fin) calculation for OA and FA types. For the sensitivity study, we have different positions(side, under) of cooling fans for forced convection of FA type. The calculation results were compared with the measurement data which obtained from 135.45/69kV ultra transformer flowrate and temperature test. The aim of the study is to assess the Fluent code prediction on the radiator calculation and to use the data for optimizing transformer radiator design.

The word 'Neo-Modern' means the revival of modernism, specially the concept of the White Geometry of Le corbusier and Mies van de Rohe, and the Neo-Modern movement in architecture indicates the leading aspects appeared in 1990's. Modern architecture was a formalistic art movement. With its historical roots, in Europe extending back to the avant- garde modern architecture in 1920's, Neo-Modern appeared with the name of New York Five, in 1970's. In Japan, there has been an outstanding movements presenting Modernism architectural charateristics, since 1980's. The characteristics of these works can be discerned from the those of Regionalism of Historicalism in 1980's. This study is to investigate and analyze the characteristics of the works of Japanese Neo-Modern architects and to contribute to defining the word, 'Neo-Modernism'. In chapter one, the background, purpose and methode of study are presented. In chapter two, the concept and historical background of 'Neo-Modernism' are studied. In chapter three, the characteristics of Neo-Modernism are studied on the basis of the main concepts and formal characteristics of modernism and New york Five. In chapter four, the tradition of Modernism inside the history of Japanese architecture were studied, specially focused on Metabolism. In chapter five, The characteristics of Neo-modern expressions used in the 18 exhibition and cultural facilities in Japan, established after 1980, are analyzed in terms of 4 expression categories. In chapter six, a synthetic conclusion is presented.
