The temporal aggregate in temporal databases is an extension of the conventional aggregate to include the time on the range condition of aggregation. It is a useful operation for Historical Data Warehouses, Call Data Records, and so on. In this paper, we propose a structure for the temporal aggregation with multiple selection predicates, called the ITA-tree, and an aggregate processing method based on the structure. In the ITA-tree, we transform the time interval of a record into a single value, called the T-value. Then, we index records according to their T-values like a $B^+$-tree style. For possible hot-spot situations, we also propose an improvement of the ITA-tree, called the eITA-tree. Through analyses and experiments, we evaluate the performance of the proposed method.

The term 'modern', in broader sense, refers to the concepts like modernity, modernization, modernism and the like, which came from Westernization impling the recognition of indigenous culture as being inferior to Western culture by comparison along with the expanded influences of the Empire of Japan. These concepts, however, rather than evolving from Western standards, came into being as a form of civilization led by Japan which had already tasted the fruits of modernization by 1920s. Since 1920s, the policy of, so-called, reconstructing Asian countries by Japan came to create eastern way of modernism, as a new East Asian trend mainly revealed in China which was against colonization after Japan's invasion and conquest of Manchuria. Therefore, Eastern' modern' unlike Western one could be understood in the widespread terminology, 'Modern(摩登)' in Shanghai, reflecting consciousness like 'Fashion' or 'Trend' in female images on a variety of visual media. By 1930s it was the most notable that 'modern' was accepted as something similar with 'Fashion', or 'Trend' in sociocultural contexts. These atmosphere had led commercial arts to enable to communicate with the public in a great deal of supports and success in Shanghai which was widely regarded as the citadel for the inflow of Western culture, among which transformations in female images were remarkable as a representative form of culture. It is also remarkable that 'historical modernity' transforming from the feudal age to modern society was considered a synchronic modernity, and nationalism was regarded as a sort of being modern, while involved in the newly-changed female images as a fashion mode. Changes in fashion including hair style in Shanghai by 1930s, as a way of expressions showing what was modern through commercial artistic productions, were easily noticed in visual media as an outlet of modern women's inner desire revealing their pursuit for new mode of life in metropolitan cities. As a characteristic of the time creating a new code of visual female images, it is notable that there existed another form of 'modern' satisfying socio-cultural needs of the general public seeking for being 'modern'.

Jeongamsa Sumano Stupa(Korean National Treasure No. 332) is a brick like stone stupa and it is considered that this stupa was built in the Later Silla period or in the early part of the Koryo period, considering its structure and style. This Buddhist stupa is highly significant in Korean Buddhism since it was built to enshrine Buddhist sarira reliquaries that 'Jajang' brought from China in the 7th century, according to the 『Overlooked Historical Records of the Three Korean Kingdoms, 『三國遺事』』. However, the stupa was positioned at the very unique location. It was positioned not at the center of Jeongamsa Temple, but at the separate edifice. The location of Jeongamsa Sumano Stupa indicates that this stupa embodies the nature of Mahaparinirvana treasure palaces and that this stupa was recognized as a solemn symbol, which reflected a sarira faith. Jeongamsa Sumano Stupa is the only brick stone stupa built in Gangwon province. It is worth noticing that this stupa was mostly made of dolostones, found around this region, and thereby regional characteristics were reflected in this stupa. The other interesting fact about Jeongamsa Sumano Stupa is that there are many records available which include information about stupa's reconstruction, considering that there aren't many records of other stupas. The most representative records are 5 pieces of memorial stones which include information about when and on what ground the stupa was reconstructed as well as information about originators of the stupa. In conclusion, Jeongamsa Sumano Stupar could be regarded as the academically valuable material since it is considered very important and helpful for understanding not only the history of Korean Buddhist stupas, but also so many other things such as construction techniques, styles of brick pagoda and brick stone stupa, and such.

The Korean have admired and lived with decorums through Jeol, a representative practical formality which expresses the decorums intensively. Jeol is the way of greeting native to Korea and an intangible culture close to Korean life style. To be remained as a culture, the traditional propriety Jeol should reconcile to the present life feflecting our history. On this viewpoint, the purpose of this research is to furnish the authority of the creative inheritance on the settlement of Jeol and other decorums suitable to the present. This research is consisted of 1) the study of the meaning of Jeol and 2) the hidtorical research through records. 'Jurye' is regarded as the oldest literature on the systematic explanation about Jeol and has been very often used down the ages. Jindong in 'Jurye' and Kodu in 'Karyejipram' are the same Jeol which expresses the grief in funeral rites. In 'Seonghosaseol', Abae which stands one knee is explained and investigated as the case of offense by the literature. And it is also interpreated as a Jeol with respect, while many other Jeol is to fall an both of kness, Abae is not performed generally. 'Yeki' has brief explanation about Kongsu Manner (to hold hands), Jeol between the king and minister, host and guest, Buinbae, Jeol in custom, wedding ceremony and funeral ceremony and Jeol in drinking manner. In 'Chunchukongyangjeon'. there is the explanation about Jeol of the minister who comes back after his duty to the king. 'Sunjajiphae' interprets Bae and Kyesang and informs that Kuesu is the most respectful Jeol only to the king, 'Seojeon' proves the Jeol habitually used in all kinds of ceremonies and etiquettes. 'Jeongbomunheonbigo' introduces the custom of Jeol in Shilla, Koguryo, Buyeo, Koryo eras by using literature and shows the commoness of both kneeling down generally. The result of this research has the meaning for the creation of life culture in the basis of the spirit 'Onkojisin'(reviewing the old and learning the new) by establishing the present Jeol with tradition.

Futurists objected the existent style, that is the conventional fashion, and took part in these disciplines of fashion to make clothes the instruments being able to represent the individuality. Giacomo Balla and fortunato Depero, pain-ters who in 1915 were to work with Diaghilev's company, were the first to see clothing as a dynamic interfaced between th body and the atmosphere, between physical gestures and the urban context, which could be translated into encounters between forms and colours, volumes and architecture. For them, clothing began to exist as an object and an event, something to be removed from a mainly static conception and made mobile, active. The interaction between movement and clothing was based on the relativity of perception : the appearance and disappearance of the body produced points without dimension or duration which served, as Balla wrote in the Futurist Mnaifesto of Men's Clothing to“renew incessantly the enjoyment and impetuous movement of the body”. The historical achievement in the effort for the reformation of Futurist, Art to Wear. First, for Futurist, clothing is removed from a static conception and focused on dynamics. Second, Balla used asymmetry in men's clothing. Moreover he supposed dynamic men's clothes by using optical intersection. Third, the after image of Chronophotograph represented rapidity. This rhythmic expression is the fore-runner in Optical and Kinetic Art of Visual Art. Fourth, Futurist emphasized flexibility in fashion. They aimed to create‘Clothing Machines’whose parts would interact to aceelerate the real and virtual, inner and outer movement of the human being. Fifth, the variety and short life of cutting skills and colors are focused and‘Fast Substance’in fashion is admitted by Futurists. Futurist concern with clothing was not lim-ited its appearance in terms of cut and colour. What important was also the way it appeared and disappeared according to fashion. It was a“fast substance”, able to reflect rapid, sudden changes of social and aesthetic taste. To reach to the aim of internationalization, Gesamtkunstwerk in our Art to Wear, it is extremely meaningful to examine art fashion which is created under the conception of Gesamtkunstwerk production of avang garde artist in the early 20th century and look at formative conscious of truth, goodess and beauty synthetically which they faced on their works of art.

Pearl gowns(Jeanju-eui)' of Princess Jekukdaejang which were imported from Yuan to Goryeo in 13'th century, but correct shape and detail were unkown. Princess Jekukdaejang was a queen of Goryeo and a daughter of Kublai Khan of early Yuan period, and pearls were the most precious jewel in Mongolia of medieval time. It is possible that the shapes of Jeanju-eui were nomadic mogolian women's costume or very new style yet in early Yuan just like sleeveless long vest. In the period of Yuan, pearls were beaded on the stiff thin fabric for summer or ornaments of ladies. Big pearls were made use of point spot of pattern or line of pattern, and small pearls were usually used to fill up devided parts or to bind outline. The shapes of deducted pearl gown are five kinds of women's deel and four kinds of long vest, and deducted parts for pearl decoration are golden band from shoulder to wrist and on the knees of gown, cloud shape collar, patches on the breast and on the back, slant collar, and patterns of fabric. Red color(the favorite color of Yuan ladies), artifical pearls, ramie, and golden brocade with the gloss of satin are selected as stuffs for sample of pearl gown, but 'reproducting old fabrics' was the most important problem in making correct pearl gowns. Suggested is a cooperation with fabric makers to develop alternate fabircs with patterns just like Yuan's.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

This study is aimed to investigate the characteristics of the elevations in the contemporary multi-family residential buildings in Paris. The survey was performed by studying 30 buildings which had won the multi-family residential project competitions, held in Paris in 2011. Since 30 buildings in the survey will be constructed in Paris in a couple of years, current trends of the elevations of the multi-family residential buildings can be extracted. Historically and also currently, in France, the multi-family housing has been studied to solve the various social problems; especially in Paris where the historical buildings and the modern and the contemporary buildings stand together in perfect harmony. The uniform elevations of the multi-family residential buildings in Korea, have been consist problems in the country. By studying the building elevations in Paris, the solutions to solve the current problems and to improve the situation, can be found. The study will be discussed in three different categories. First of all, the volume and the mass of building in the survey buildings, will be analyzed. Secondly, the openings in the facade, such as the windows and the balconies of the survey projects, will be analyzed. Finally, the materials and the colors of the facade will be discussed. By analyzing the elevations of the multi-family residential building projects, which had won the competitions, and are soon to be built in Paris, the various experiments and the attempts in building elevations, currently happening in Paris which is mostly known as a Haussmann style city, can be presumed, as well as the willingness of the city to reserve the historic buildings in the city.

If the motion is universal over the differences between the ancient age and the modern age, and between primitiveness and civilization, It is required to be studied, which make it possible to discover the universally valid interpreting elements of various societies and cultural phenomena. The study on the motion, as a base of universal motion study on animation and character modelling is considered as a very important part. The sampled motion prototype was classified by the continuity and the synchronicity that is a basis of modular analysis and of motion flow. Koguryo's mural paintings in old tombs has been the heritage and the symbol of the nation's historical identity and pride in Korean history. Koguryo is obviously a part of Korean history, which are of Korean elements. Accordingly, the mural paintings that this study has explicated is the origin as well as the history of Korean visual animation history, while the analysed and restored motion prototype is a module of Korean motion with golden section proportion.

Stability of the moving historic sites have something to do with the degree of easiness of work as well as physical property of polymer product. These agents should be able to use without the effect of outer environments like water or low temperature and must have stability during progress of working the peel off Urethane pre-product from Epoxy surface. So, we synthesized low viscosity epoxy resin and hardener with best physical quality and separation media for the moving of historical sites. These products have very good tension strength, adhesion strength, low viscosity and various physical properties that the users want. Particularly, separation media products have good separation of Urethane pre-products surface and Epoxy final product surface.
