The purpose of this study is to analogize the appearance of Korean Ancient Architecture in view of the Stone Remains from 3 Kingdom Period to Unificated Shilla Period. But in these period, there is no building remains but some stupas and fine arts. Especially, there are many architectural appearance and revealing signature in these Historical Stone remains. Architectural elements which are analogized by stone remains what has value as historical materials by preservation of original form from 3 Kingdom Preiod to Unificated Shilla Period are as follows : 1) Platform, the representative characteristic of Korean traditional architecture, was frame structure and accumulate structure. And circular or square footing stood a same shape column on it is put on the platform. 2) In the case of column, there used entasis column and inclined column and circular chamfer technique was applied on the top side of it. Upper side of column, capital and head pentrating tie that small bearing block was put on the center of it was joined. And longitu야nal rest(長舌) supported a cross beam. Capital and small bearing block had no bottom heel, and heel side was curved and straight. Centered bracket structure was often used, and multi bracket structure is not used yet. Inward incline technique was used. 3) Inward opening pair door which had lintel, threshold, doorjamb was usually used, Fixing stone was used for structural safety, and circular handle and lock was used for decoration. Handrail was used on the edge of wooden floor for decorative effect and safety. 4) Square rafter and circular rafter were used in the same period and so did flying rafter. Double eaves and single eave were used in the same period but, single eave was usually used. In this period, square rafter was usually used. This would be studied more by comparing with Japanese wooden architecture. 5) Hipped roof was used and half-hipped roof was not used yet. In front of th hip, there are small sculpture called Jap-Sang(雜像), and windbell was hang on the end of the hip rafter. Concave roof tile, convex roof tile, round eaver tile, decorative tile at end of roof ridge were used. Lotus style was well used on the face of roof tile for decoration. From the results of this study, wooden architecture of Unificated Shilla period was simple compare to Koryo dynasty and Chosun dynasty but, it had some brilliant character. It was hard work that analogized the form of non-existent wood architecture of Ancient Korean period by restricted stone remains. But, in addition to the results of this study and research of old documentations, more study should be go on.

This is a study on the ㄱ-shaped church in Korean Protestant churches. Since the Protestantism had been introduced into Korea, the style of ㄱ-shaped church was the popular style that have been fashioned in all the country of Korea. When the Protestantism was introduced into Korea, ideology which ruled over the Society of Chosun Dynasty was the Confucianism that emphasized the precepts, for example, the loyalty for the King, distinction between the sexes and so on. The Korean Protestants built the church which had ㄱ-shaped plan, so that they solved the second problem : 'distinction between the sexes'. The style of the ㄱ-shaped church is one of the characteristics which distinguish the Korean church from other nations'. Actually the ㄱ-shaped churches had been built by Korean Protestant denominations, from the early days of introducing the Protestantism till the end of 1920's. Even though most of the style of the ㄱ-shaped church is replaced with the modern style according to the extension of religious influence, luckily the ㄱ-shaped two churches : Kumsan Church(1908), Toodong Church(1929) are in existence in the Provice of ChonBuk. The purpose of this study is to make the architectural characteristics of the ㄱ-shaped church clear. This study is based on the actual survey of the ㄱ-shaped churches in existence: Kumsan Church, the Toodong Church and on the documents, photographs, interviews and so on for investigation not existing one now. The ㄱ-shaped church have the plan to separate men's side from women's with a right angle and have a pulpit which was placed at the meeting point of the front part of men's and women's sides. Generally, seen from the court, the churches have men's side in left and women's one in right. There was a screen blocking both sides in the church. But it disappeared in 1920's according to the change of the social conventionality. Most of its structural form is the Korean wooden style. The ㄱ-shaped church appeared in a transition period of the Korean church architecture.

The major findings of basic women wear in genre painting were ; 1. Due to the influence of Shill-Hak (practical science) philosophy, Jeogori became shorter and a tighter fit came to be the norm. 2,. The shortening of the Jeogori influenced a longer Chima with a wider span providing comfort in movement or at work. The end of the skirt was often held by one hand to the waist adding to comfort. This was called the Go-dul-chima(Lifted Chima). 3. Because the Geo-dul-chima exposed a portion of one underwear at the bottom of the dress this influenced the "irnamentation' of underpants and underskits. 4. Collars or lapels came in the form of Dang-ko, Kal, Mok-pan and Ban-Mokpan. Among there Dang-ko style collars were the most common which allows us to conclude that this was the most popular. 5. The most commonly used colors for Jeogori were white (39.8%) and jade(18.3%) . The most commonly used colors for CHima were deep blue(34.4%) and jade(20.4%) . The lower Chima used the darkercolors to give stability to the overall costume. 6. Clothing had the function of differentiating the classes. Only the Yang-ban were allowed to wear the Samhijang Jeogori and the Gob-Chima(double layered Chima) and the knotting of the Chima to the left. But the painting show that these rules were not adhered to in the strictest manner. With the bases of these types of chima and Jeogori can look at the characteristical beauty of the ordinary women during the late Cho-sun dynasty. First is the beauty which comes from mystery of those parts of body which can not be seen. A sense of subtle and sensual beauty as well as that coming from the enlargement of reduction of the upper body, narrow waist and abundant lower body parts creating an ideal silhouette of sexual charm. An expression of emotion through clothing by those who lived during those times.

In KOREA, the history of weaving is so long even in prinitive, there are the traces of fabric emmision using Spindle already in the Neolithic age. And coming up to the period of Three States, becoming active of cultivation of fibers, it can be known the variety of kinds and the production of fine products by improvement of new method of weaving using weaving machine. In the period of shilla state, there is a record of making the fine fabrics with 28 bracts. But wearing of silks fabrics was limitted for only the nobility and common people were wearing native thick hemp clothes. Also in the period of Korea state, they were wearing the hemp clothes by cultivation of hemp. The good quality products were worn by the King or the nobility and women in KOREA made their best with whole efforts to pay to the authorities with woven products of hemp clothes, so in the 14th year of King Chung- Ryul, King prohibited the presentation of fine hemp clothes by his order. By the end of KOREA state, before the production, common people was mainly wearing the hemp clothes. Coming up to the Kingdom of Chosun the sericulture was promoted by establishment of the sericulture encouraging low. Therefore the working hours of women were highly increased. The products of Song-do, Chin-ju for cotton clothes, those of Han-san-the same now as in old times-for ramie clothes, those of Han-Kyung province and An-dong for hemp fabrics were estimated as the best qualities. And the hemp clothes of Kang-won province is not so fine but is very useful and famous for mourning clothes and summer clothes for the farmer. It is true that our history of weaving was begun with hemp as a continous and precious friend of common people during all the historical periods-even though for a while it went backward because of chinese silks.

It has been recognized that the cityscate identity is a very important factor in a modern city. It is necessary to have a variable view to urban comunities for understanding the cityscape identity. We have investigated the contents of archaic texts such as the geography for tracing a cityscape identity to its origin in a city. Because it has been written about politics, economics and culture of a specific area in the geography based on deep interest to the city, we can look into the early image of the cityscape closely after searching of archaic texts. It is also significant to stdy with archaic texts of geography since these studies have a correlatio to the understand of an area and the keeping of historical conscious which are fundamental of cityscape identity. We have studieds on the area of Cheongju from the middle of Chosun dynasty to the end of this kingdom, since that many geographies were described those days. It was selected "Go-Reo-Sa" and "Se-Jong-Sil-Lok" Geography, "Sin-Jeung-Dong-Guk-Y대-Ji-Seung-Lam" "Dae-Dong-Ji-Ji" "Dong-Guk- Yeo-Ji-Ji", "Jeug-Bo-Mun-Heon-Bi-Go Yeo-Ji-Go", and "Taek-Li-Ji", as archaic texts of geography because these texts described in detail about city and gave a clue to speculate an image of city. The major results are as follows; 1) It was described about the cityscape in those archaic texts are metaphysical image, existing and usable elements of cityscape, lost resources of cityscape. 2) The metaphysical images are neither objective nor consistent in the each archaic texts. But the metaphysical image of old city suggests good insight for the application to the modern city image. 3) It is necessary to the careful onsideration about the existing elements. 4) There are variable programs about the lost resources of the cityscape, in accordance with the possibility of the restoraton. 5) The physical and visible factors and non-physical and invisible factors are equally important elements of the cityscape identity. Our research suggests that it is necessary to understand in detail how those factors of cityscape identity have changed with the changes of the times, and how those factors affect the modern cityscape identity.

The issues concerning the nature of the attitude toward the study of national language may vary from country to country, depending on the national or racial characteristics. The problem domains and the methodologies dealing with them may vary accordingly. Ever since the Korean language was equipped with a writing system in the year of 1443 through King Sejong's long-cherished desire, investigations have been constantly made into the real nature of the language itself in pursuit of a better method for representing the spoken language in written form. This is how the study of the Korean language began to take shape. Among such investigations are Hunmin-jeong-eum(the Korean script: 1446) compiled by Jiphyon-jon, the royal office of schloarly researches, Doongguk-jeonghun-yokhun (the orthodox script of Korean: 1448), Hongmu-jeonghun-yeokhun(interlinear gloss for the Chinese script of the Ming Dynasty: 1455), An Orthodox Approach to Written Korean (1909) by the institute of the National Script, Re Standardized Spelling System (1933) by Chosun Language Society, An Authorized Dictionary of Standard Korean (1936), How to Write Borrowed Words(1940), and A Grand dictionary of Korea (1947-57). Chu Shi-Gyung's Phonetics of the Korean Script(1908), Korean Grammar(1910), and Sound Patterns of Korean(1914) were all written in this vein; so was Choi Hyun-Bae's Uri-mal-bon (the rudiments of Korean Grammar: 1929/1937). All these achievements in the study of the Korean language are the end-products of the constant endeavor to solve the issues related to the spoken and written farms of the Korean language. And this is how the uniqueness and autonomy of the language study in korea have been established. It should be borne in mind, however, that, in seeking solutions to the problems inherent in the Korean linguistic studies of foreign countries. On the contrary, they have been very active in accommodating such results. While they have set up their problem domains on the basis of the korean language, they been progressively open-minded in looking for the solutions to the problems at hand.

The Tongdo temple have been transformed continuously since its first establishment about 1300 years ago. Nevertheless three critical elements specified by 'Jajangyulsa', founder of the temple have not varied over the times but rather strengthened and strongly combined. All elements and doctrines of the religion coexist and form a harmony within the whole of the temple. This researcher examined what changes, or combinations, in spatial formation were sought for such unique structures of the Tongue temple by focusing mainly on the Sangrojun area of the temple to obtain the following findings. First. unlike a work by a Japanese researcher 'Sekino Tadashi', the east yard of the main building was found located on the section line which corresponded to the separation line of Yungkuncheokdo(營建尺度=measure running) from the edge of the Keumkangkyedan(金剛戒壇 =Buddhist platform) embankment to the corner column of the Kamrodang. This was confirmed as a result of the review of photos shown in [Chosun Kojukdobo]. Second, the number of stairs used for the Keumkangkyedan was thought to become three when the temple was firstly restored in 1379 as a result that this researcher reviewed Chinese literature 'DoSun' and [Kyedandokyung(戒壇圖經)], records by 'Lee saek' and 'Jung Shihan', studies of Yungkun measure and actual changes in the temple. Then the temple was forth restored in 1705 when the second of the stairs was changed in area and height and at the same time grounded hard for a space for a Buddhist service. Third, the roof of the main building was probably changed in shape during the Koryo period when the plane structure, furnish arrangement, emphasized front, stone lanterns of the building and political factors of that time were all considered. Fourth, the main building was Initially designed to provide a Buddhist sermon service which was assumedly followed by a similar service at a Keumkangkyedan. Thus the main building had a small window on the northern side which might be opened up to look out or otherwise go outside like a door. However, the window was probably locked up like a surrounding wall since the main building was entirely repaired after the end of Japanese invasion of Korea in 1592.

The purpose of this research is to design and to produce actual high value added wedding dress comprised of the pear blossoms pattern(梨花紋), which is one of the traditional patterns which was not researched to this day, and of the Dang-$\breve{u}$i(唐衣) image which reflects our concept of beauty as if as a means of conducting empirical study for the application of traditional Korean patterns to the contemporary application. pear blossoms effectively signifie the image of beautiful bride thanks to the pure, graceful and clean image of white flower, both in the external and internal aspects. The Dang-$\breve{u}$i of the Chosun Dynasty, which is another motif is one of the representative clothing that expresses the beauty of the curve when it comes to the Korean culture as traditional wedding dress. Attempt was made to develop design for wedding dress that expresses the Korean style beauty that combined the tradition and the modern. Towards this end, the project was composed of the Korean-like Ewha, image of the Dang-$\breve{u}$i I, II and III to design three dresses. The Dress I presents the image of pure, elegant and beautiful bride, while Dress II represents the pure and city like trendiness of the Korean women today as bride. Dress III was made centered on the image of elegant, and chaste bride. As for the materials used, hand-woven silk and silk organza used for the traditional clothes. As for the ornaments, embroidery, quilted work, beads, corsage, burn-out and other techniques were used for expression.
