In order to determine the horizontal and vertical distributions of metals and prospect the recent metal pollution history in Nakdong Estuary, we took surface and core sediments. Maximum value of organic matter occurs at the upstream site located 4 km from Nakdong barrage, and the concentration of trace metals (Zn, Cu, and Pb etc.) decrease seaward in the estuary. The sedimentation rates, based on $^{210}$Pb$_{ex}$ and $^{137}$Cs activities, were 0.34 cm/yr in inside of barrage (core 1) and 0.25 cm/yr in Changrim (core 4). Sediment mixing layer does not exist in core 1, where anoxic condition is known to be prevail. The topmost sediment layer of core 4 (<3.5 cm) is severely mixed. At sites 1 and 4, concentrations of Cu slowly increased during the period of 1920-1970, rapidly increased during 1970-1990, and followed by slight decrease after 1990. Zn contents increased in early 1960s and peaked in 1993, and followed by decrease after 1990s. Pb has increased continuously since early 1970s. At the downstream of the barrage, Cu and Zn have increased in the topmost layer. The trend of increase of Cu is evident after 1950 (11 cm in sediment depth). Overall trend of heavy metal concentration clearly indicates the pollution has been increasing after the construction of the barrage.

The purpose of this study is to analyze the relation between the beauty of human body and the fashion illustration in each period And I attained my object through the investigation of features and changes of illustration which is given a vivid description of the features and development of ideal humam body beauty. By various methods I studied this subject. Frist I refered to sundry records Secondly I investiated the fashion illustrations which are included in Vogue. On the basis of this data I grasped the ideal types of human body beauty which is founded during the social change in each 10 years. And I analyzed the relation be-tween the ideal type and fashion illustration which show the change of fashion. The summary of result is as follows. 1. In the early part of the 20th century the beauty of human body is represented with the figure of large-sized beauty which emphasize shoulder and bust. And fashion ikllustration show 9 life-size broad shoulder full bust lim waist and hourglass silhouette. 2, In the 1910s the swell of strength vanishes gradually and shoulder and sleeve are straight type. And fashion illustration show 7 life-size high waist line. And that is tublar sil-houette of high waist and streamline shape in which bust and hip are not emphasized. 3. In the 1920s the ideal type of human body beauty is straight type which shows flat bust and unexaggerate hip. And fashion illus-tration is about 8 life-size tublar silhouette of low waist and lunger and slimmer and young style in which bust and hip are not emph-asized. 4. In the 1930s the ideal is womamly slim and long style. Fashion illustration is about 8 life-size and slim & long silhouette in which waist line is emphasized and bust and hip line come out. 5. In the 1940s the ideal type is womamly style which has narrow shoulder rich bast and slim waist. And fashion illustration is about 7 life-size and hourglass silhouette which has unartificial shoulder slim waist and empha-sized bust. 6. In the 1950s the ideal type is that of ro-bust health which emphasize build and muscu-lar system. And fashion illustration is 8.5 life-size and show full bust and made waist slimmer. That is sheath silhouette. 7. In the child who has full face with large eyeball slender and long leg: narrow and immatured body comparatively big head. And fashion illus-tration is 7 life-size and show slim and long neck flat bust long and slim limbs and big head. That is H type silhouette. 8. In the 1970s the ideal type is high stat-ure flat breast small hip and wide shoulders. And fashion illustration is wide shoulders and slim waist as 11 life-size and straight sil-houete. 9. In the 1980s the ideal type is extremely emphasized breadth of shoulder because healthy body and muscle are recognized as the symbol of ideal attractiveness. And fashion il-lustration is about 8.5 life-size and show mus-cular slim type that is slim silhouette. 10 At the present time the ideal type is slim and tall type which is empasized healthy beauty. And fashion illustration is 12 life-size which has healthy body and skin So that is slim and long type.

The characteristics of the records management systems of the Japanese colonial government can be summarized as follows. First, the Government General adopted a "decentralized retention" of public records. The Government General did not establish its own archives for central preservation of permanent public records. Colonial agencies established its own records office and the records office managed the records its agency created. Secret records and police records were exception. They were retained by the Secretary Office of the General Affairs Division and Police Division of the Chosun Government General respectively. Second, filing systems and retention periods of the public records followed the hierarchic structure of organization. In the headquarter of the government, records were filed by a "bureau-division-activity-file" classification system and a retention period of a file was given automatically by each unit the file belonged. A closed and cut-off file was retained and arranged according to its creating unit, creating year, and retention period. The filing system was easy to use once the filing system was established well, but to make it work effectively changes in activities and organizations should be on a reflected regular basis. It had an advantageous effect that permanent records could be preserved in a unified way throughout the organization. However, it is very critical to determine the permanent records in a professional way. Selection of the permanent records should be done professionally and in a historical perspective. Otherwise, the records retained as permanent records were not the records having an enduring value. And that was not done by the colonial government. Third, classification and scheduling of records were carried out by a creating division, rather than by the Records Office, mostly from the 1920s. Compilation of the records was also done by the creating agency. It implies that the records management lacked the professionalism. In conclusion, the records management system of the Chosun Government General wes nither modern nor user oriented. It managed the records for solely administrative purpose, i.e. effective colonial rule. The legacy of the colonial records system still exists in the public records system in Korean government. One should criticize the lack of will and efforts to modernize the public records system since the establishment of the Korean government while should reflect the historical origins of the records system in Korea.

Beginning of the human ecology in 1920s, the efforts for applying the environmental values to a policy have been embodied by the enactments of international agreement and relevant laws. The government has been struggling to adopt the environmental values for the policy by enacting the relevant laws and establishing the environmental value evaluation information (environmental conservation value assessment map, eco-natural map, biotope map). In spite of the efforts to apply the environmental value assessment information for the habitat potential of wildlife, the application is being challenged by the discrepancy in methods and criteria. Thus this study intends to measure the potential of wildlife habitat and apply it to the spatial value classification for the application plan of wildlife habitat potential in policy. Maxent was used for the habitat potential and the land types were classified depending on the surface and land use pattern of cadastral map. As a result, the policy matrix including conservation strategy(CS), restoration strategy(RS), practical use strategy(PS) and development strategy(DS) has been deduced as CS $13.05km^2$(2.38%), RS $1.64km^2$(0.30%), PS $162.42km^2$(29.57%) and DS $8.56km^2$(1.56%). CS was emerged mostly on forest valleys and farmlands, and RS was appeared in the road area near the conservation strategy areas. Boryung downtown and Daecheon Beach were the center of DS, while the forest and farmlands were presented as PS. It is significant that this study suggest the new approaching method by comparing the wildlife habitat potential with the land type. Since this study evaluated the environmental value by one species of leopard cat (Prionailurusbengalensis) with Maxent model, it is necessary to apply the habitat potential measuring method for various target species as further research.

Sauna, or hanjeung (汗蒸) is a physical sweating method that uses external heat to forcibly raise body temperature to treat cold damage disorders (傷寒) in traditional Korean medicine. This study focuses on the fact that the sauna was recorded as a healing and bathing method on the Vinaya Pitaka (律藏), and investigates the records of folk sauna therapy of Joseon Dynasty from the perspective of Buddhist medicine which played a significant role in ancient medicine history in Korea. Although the word 'hanjeung (汗蒸)' first appeared in "The Veritable Records of King Sejong (世宗實錄)" in the Korean literature, this study aims to confirm the possibility that the tradition of Buddhist sauna bathing has already existed since the Three Kingdoms period in Korea, based on the fact that sauna bathing was recorded in the Vinaya Pitaka and that the ancient Buddhist bathing culture was introduced in ancient Japan. In addition, the succession of the Buddhist sauna tradition by Goryeo will be traced back through the records of 1920s urban saunas in Gaesung (개성) which was the old capital of Goryeo and had a strong tendency to adhere to traditional Goryeo customs. Finally, the study tries to identify the elements of the Buddhist sauna bathing on the records of folk sauna therapy in the Joseon Dynasty. As a result, this study examines how the Buddhist sauna bathing culture in ancient Korea, which was led by medical monks, spread in the general public and influenced the folk sauna therapy in the Joseon Dynasty.

This research examines embroidery panels of Hwarot belonging to the Victoria and Albert Museum (the V&A). There are a total of seven objects and are all disassembled into clothe pieces. They were classified into two groups according to their acquisition year. One group, four objects, was acquired by the Museum in 1920. Considering their materials, embroidery threads, techniques and formative characteristics of patterns, it can be assumed that the objects formed an original dress, Hwarot. Although they look very similar to the embroidery patterns of Hwarot belonging to National Folklore Museum of Korea, they are more finely embroidered with very thin embroidery thread that uses the Jarisu technique. There are some differences in used embroidery threads and embroidery skills between Hwarot artifacts of the National Museum of Korea and the V&A. The embroidery of the National Museum of Korea used thicker threads and longer (approximately 0.7cm) Jarisu stitch techniques. With these details, they would have been made in different time periods. Comparison of the V&A and Changdeok Palace' Hwarot objects show that their patterns' motifs are almost similar but the pattern units, expressions and embroidery techniques are different. Regarding the colors of their patterns, it is noticeable that the peonies are generally expressed in reddish and the lotus patterns are expressed in either bluish or purplish color. It seems that they are contrasted with red-colored flowers and show harmony between yin and yang symbolically. Three artifacts of another group were acquired in 1925. Two of them show patterns almost the same as those of the sleeves of Hwarot (no.33156, no.33158) in Chicago Field Museum collection. The pattern of the remaining object is very similar to Hansam of Hwarot (no.33158).

This study is to investigate the meaning and value of Usonian Automatic House System(UAHS) of Frank Lloyd Wright in his later period, focused on materials, methods, and his thoughts. The results of this study are follows. UAHS was the outcome of moderate cost and prefab house which Wright had successively attempted after the early Prairie period. The construction was simple and comparatively cheap, but subsequent automatics were difficult and expensive to build. Nevertheless, it was sufficiently flexible to support a rather wide range of house designs. Concrete was the inert mass and a plastic material. Wright saw a kind of weaving coming out of it. He also saw a kind of concrete masonry, steel for warp and masonry units for woof in the automatic concrete block. The reinforced bars in hollowed joints of concrete block increased the safety factor and affected the expression of the construction through the stabilization they provided. But they did not give concrete block the capability of structural span. Standardization as the soul of the machine might be seen in UAHS. The concrete blocks were more cheap, lighter, and larger hollowed plain than textile blocks in 1920s. But the variety of pattern and different block types in the UAHS were achieved at some sacrifice of standardization. The repetitive nature of production was compromised for artistic goals. The sense of compromise was not maximized, however, because the units as installed looked far more repetitive than they actually were.

The purpose of the study is to give new aesthetic values of black dress one of the important items in contemporary women＇s fashion. Through the work, to give the new aesthetic characteristics that women really needed can be found. This study was processed by fashion books and articles, literal material with fashion photos which were related fashion trend from 1920 to the present. The results are as follows: In early 20th century, the black dress, which had simple form pursuing function like little black dress. In the middle of the 20th century, elegance and minimalism was represented by black dress, expressed erotic images together with see-through fabrics. In the end of the 20th century, body conscious style of black dress expressed sensual images of women. Modem black dress has design characteristics of the form: simple, close, exposure type and of the materials: matte, transparent and dazzling etc. Simple type emphasizes feminine elegance, while close type and exposure type disclose woman body curve to express erotic images. Matte materials made black dress express feminine elegance while transparent materials and dazzling materials made black dress express erotic and sensual beauty. The aesthetic characteristics of black dress were as followings: Sensualism expresses sexual attractiveness of women-close type and exposure type black dress and see-through materials and dazzling materials made black dress. Simplicity of extreme decoration effects are expressed through black dress having temperate and simple form. Femineity expresses traditional femineity to emphasize chaste, modest and elegant women images-the black dress, which is made of simple form, velvet and satin materials. Modernism combines black colour, which is called modem colour, with simplicity and function factors and pursues simple form. Ascetic practice controls mental and physical desire of the individuals, simple form without decoration covering up woman body and box type silhouette of black dress. Therefore, the study on image of the black dress, which have made appearance at modern fashion, is thought to help develop fashion trends and design, through which modern women express themselves and their beauty.

Our ability to predict hydration behavior is becoming increasingly relevant to the concrete community as modelers begin to link material performance to the dynamics of material properties and chemistry. At early ages, the properties of concrete are changing rapidly due to chemical transformations that affect mechanical, thermal and transport responses of the composite. At later ages, the resulting, nano-, micro-, meso- and macroscopic structure generated by hydration will control the life-cycle performance of the material in the field. Ultimately, creep, shrinkage, chemical and physical durability, and all manner of mechanical response are linked to hydration. As a way to enable the modeling community to better understand hydration, a review of hydration models is presented offering insights into their mathematical origins and relationships one-to-the-other. The quest for a universal model begins in the 1920's and continues to the present, and is marked by a number of critical milestones. Unfortunately, the origins and physical interpretation of many of the most commonly used models have been lost in their overuse and the trail of citations that vaguely lead to the original manuscripts. To help restore some organization, models were sorted into four categories based primarily on their mathematical and theoretical basis: (1) mass continuity-based, (2) nucleation-based, (3) particle ensembles, and (4) complex multi-physical and simulation environments. This review provides a concise catalogue of models and in most cases enough detail to derive their mathematical form. Furthermore, classes of models are unified by linking them to their theoretical origins, thereby making their derivations and physical interpretations more transparent. Models are also used to fit experimental data so that their characteristics and ability to predict hydration calorimetry curves can be compared. A sort of evolutionary tree showing the progression of models is given along with some insights into the nature of future work yet needed to develop the next generation of cement hydration models.

Existing research for store has been localized in that of Seoul area, and research for the Japanese style store built under the rule of Japanese Imperialism has not been done properly owing to national sentiment. This research established Naju that inland pillage is available along Yeongsan River after opening of Mokpo harbor. I will compare modernization developmental process of building of Korean style store with that of Japanese Style store, so obviously try to make clear the activities of modernization by linking social and economical change with Joseon merchants' life. I will try to light up the position of korean style store in Naju area in history of architecture by analyzing two styles of stores into urban architectural element, putting process of change in order and translating it according to flow of age. The development process of Korean restaurant stores and that of Japanese counterparts are rather relative. Whereas Japanese accumulated wealth through oppression and exploitation of the people of Joseon the former dynasty of present day Korea, the people of Joseon could not but be oppressed and depressed. On the other hand, while the dynamic liberation movements of Joseon merchants managed to develop based on the vitality that was growing ever more, Japanese chose to back down to some degree by exercising appeasing policy. The efforts to take initiative by shattering off the submissive attitude can be found from the ability fostering movement, Gwangju students campaign and new construction or remodeling of hanok the traditional Korean house as commercial building in the 1920s. The changing phase of the people breaking away from subjugated relation to subjective attitude can be found in the commercial districts.
