Stochastic weather generators are commonly used to simulate time series of daily weather, especially precipitation amount. Recently, a generalized linear model (GLM) has been proposed as a convenient approach to fitting these weather generators. In this paper, a stochastic weather generator is considered to model the time series of daily precipitation at Seoul in South Korea. As a covariate, global temperature is introduced to relate long-term temporal scale predictor to short-term temporal predictands. One of the limitations of stochastic weather generators is a marked tendency to underestimate the observed interannual variance of monthly, seasonal, or annual total precipitation. To reduce this phenomenon, we incorporate time series of seasonal total precipitation in the GLM weather generator as covariates. It is veri ed that the addition of these covariates does not distort the performance of the weather generator in other respects.

Applying the globalization theory to the fashion phenomena which regarded the phenomena of the contemporary culture as globalization, this study had an object of looking into the globalization tendency of the fashion phenomena shown Paris, London, Milno, New York, Tokyo, and Seoul collections from 1995 to 1999. The results of this study were as follows; 1. It was the blend of romanticism that was the most common trend shown at the six world collections. 2. The works appeared at the six world collections showed the regional peculiarity under the historical background or the sociocultural influence each city had. 3. Another character appeared at the six city collections was the appearance of multi-ethnic style mixed various regional motive at a work. After all, the world fashion phenomena in the second half of 1990's could be condensed into globalization appeared homogenization, regionalization and hybridization at the same time.

We seek the possibility of application of ICT(Information ＆ Communication Technology) to the experience learning in mathematics. Especially we focused on regular polyhedron in the middle school mathematics and on geodesic dome. We investigate related historical tales about the subjects which seem quite helpful of motivating to understand them. Then by using them and by ICT we develop an experience learning program for geodesic dome as an application of regular polyhedron. Through the program we expect that students show positive attitude in mathematical tendency and curiosity about mathematics and that the application of ICT to the experience learning in mathematics is very effective to improve their learning skill in mathematics.

Through researching 鄕藥救急方, the oldest medical text published in Korea in existence known to date, a study from a Traditional Korean Medicine perspective was conducted. This study aims to observe the treatment of oral, glottal, labial, and dental diseases starting from 統一新羅時代 to the Koryo dynasty from a historical perspective and also find out what clinical significance it withholds. "鄕藥救急方" proposes methods of nurturing the teeth and in doing so displays the tendency of Traditional Korean Medicine of putting much weight on preventing diseases and nurturing the body. "鄕藥救急方" considers the oral, glottal, labial, and dental diseases as not only fundamental problems in itself but also treats them from a perspective that they are results of disharmony among the five viscera and the six bowels. The treatment methods mentioned in "鄕藥救急方" are directly cited in "鄕藥集成方" of early Chosun dynasty. In "東醫寶鑑" of mid-Chosun dynasty, however, changes and modificatios are made to the prescriptions.

This study was carried out to clarify the stochastic characteristics of monthly rainfalls and to select a proper model for generating the sequential monthly rainfall amounts. The results abtained are as follows: 1. Log-Normal distribution function is the best fit theoretical distribution function to the empirical distribution of monthly rainfall amounts. 2. Seasonal and random components are found to exist in the time series of monthly rainfall amounts and non-stationarity is shown from the correlograms. 3. The Monte Carlo model shows a tendency to underestimate the mean values and standard deviations of monthly rainfall amounts. 4. The 1st order Markov model reproduces means, standard deviations, and coefficient of skewness with an error of ten percent or less. 5. A correlogram derived from the data generated by 1st order Markov model shows the charaterstics of historical data exactly. 6. It is concluded that the 1st order Markov model is superior to the Monte Carlo model in their reproducing ability of stochastic properties of monthly rainfall amounts.

Ornament in late nineteenth century Art Nouveau movement, especially abstract ornament in Viennese Art Nouveau, has a very complex aesthetical background. Ornament, for them was not just decorations in outer appearance, but a determinant element of formal languages. Abstract ornament in Viennese Art Nouveau has its theoretical and aesthetical bases in the Interpretation of nature, that is, the theory of the abstract ornament was founded on a new interpretation of nature, which, in its turn, was derived from the differentiational selection of the contemporary views of nature. The modernity of abstract ornament consists in the very fact that it was founded on a new interpretation of nature. This study alms at reviewing how the new interpretation of nature by abstract ornament criticized, rejected and accepted the contemporary views of nature. The overall tendency of this study is to synthesize and analyze the historical background of Viennes Art-Nouveau in regard to aesthetic theories of nature. The analysis method of this study is interpretation of written documents which are related to the issue.

The purpose of this article is reviewed the historical background and development of oral care devices in the ancient civilization. Through an evolutional process of oral care devices, the prevalence of periodontal diseases and dental caries has revealed decreasing tendency. Because of the changing the role of the toothbrush, the name of brush should be alter from toothbrush to oral brush. Recent we can apply toothbrush to tongue cleaner to diminish the oral breathe odor. Selection of the toothbrush for fittable for each and every person is the one of important point to maintain the oral hygiene. including check-up the oral hygiene status after toothbrush with disclosing solution. This review of literature suggest that the most important way to maintain the oral health shoul be included the selection of proper toothbrush for each person and confirmation of result of toothbrush in oral cavity after had learned tooth brush instruction from professional person.

The general tendency of approach to Korean Design History has been focusing its primary interest on the grand story in relation to the problems of modernization in political, economical and social aspects of Korea. In the discourse of modernization, however, there are two sides immanent in the modernization: there is the formal, institutional and authoritative modernization developed inside the capitalistic mode of production and the informal, individual and cultural modernization manifested in the mode of everyday lives. Especially, despite the viewpoint of the latter being embossed as an alternative approach in various areas including the academic world of history since the collapse of socialism, the historical recognition of the phenomena of modern design by the Korean design historians is more like the 'history from the above' that exists at the level of the discourse outside the reality rather than the 'history from the below' that exists within the ordinary life. To grant a sense of balance in such frame of historical understanding, it requires the restructuring the design history of Korea through the cultural perspectives from having the representation of mundane lives realized by the voluntary design activity of the common people as research subjects. One of the methods to acquire an answer to such problem is decoding, in the manner of 'cultural history', the life-long domestic artifact made by Madame Yang, Gap Jo (currently 87 years of age) who is a model of typical Korean mother. Through the historical rumination on the traces of unpretentious lives of the people that has been buried under the grand narrative of the Korean Design History, a new era aimed for the historical prospect of Korean design as cultural history will be possible by excavating the petit yet multi-layered meaning of Korean designs.

This study is about the similarities and the individualties of the traditional costumes in the ruling classes of Koguryo(高句麗), Bakjae(百濟), and Shilla(新羅). The analysis is based on the views of historical reformation on$\boxDr$Sam-gooksagi(三國史記)$\boxUl$Bongi(本紀). The costumes that were worn by the governing classes are categorized by the following, official duties, wars, ceremonies, and recreations(hunting). Up to the present time, there has been a great tendency to emphasize the similarities of the Three Kingdoms' costumes among most of academic researchers. However, the conceptions of individualities of the costumes among the Three Kingdoms were conceived by the facts that geological environments, political systems, social traditions, social aspects, and foreign affairs. The Three Kingdoms had different official rank systems along with official costume systems. Monopolization of official positions of the ruling parties tried to show their dignity and authority through styles of their costumes. The costumes of Koguryo were greatly differentiated by geographical regions ; One direct example is cheak of Pyoungyang and Anak regiona was named as official hats of rulling parties of Kokuryo. However, in this study, the cheak was viewed as a product of influences of Chinese costume. Further-more, the laguan was named as mooguan. Costumes of ceremonial occasions were heavily decorated to symbolize dignity and auth-ority. Metal ornament of headgear and belt, metal shoes were con-sidered as ceremonial costumes. the tight hunting costumes of Koguryo shown in mural pain-ting costumes of Koguryo shown in mural pain-tings were presumed to be spring and autumn clothing. Excavated from Neungasnlee, the hunting costumes inscribed in the gold incense burnner were confirmed as hunting costumes of Bakjae. The individuality of the costumes of the Three Kingdoms could also be supported by the fact that they had different climates. The temperature difference between Gipan region and Kyoungjoo(慶州) region was emphasized. Especially winter clothing would have had a big difference in style than the summer clothing. Through the research summarized above, this study was able to confirm that each of the Three Kingdoms had developed individualized costumes based on their geographical, cultural and environmental factors. Furthermore, through this study, it was possible to find out the difference as well as the similarities of their costumes according to each of their people's sociopolitical status, awareness of indepen-dence, andunique historical and traditional charactoristics.

Present work aims to analyse the spatio-temporal distribution of Korean bamboos. The northern limit of Korean bamboo species occurs at Baekryung Island(124°10'E, 37°55'N), Hoochang(41°22'N) and Myungchon(129°41\`E, 41°10'N). The presence of bamboo fossils in Korea dates back from Tertiary, but widespread use of bamboos can be noticed since 1454. Reconstructed ranges and temporal changes of bamboo, based upon the eight historical records from 15th to 20th centuries, indicates that both climatic and anthropogenic factors were responsible for the changes of distributional range. The spread of bamboos was balanced by its disappearance due to regional development, and the total bamboo area showing little change. Due to the tendency to spread extensively by means of underground stems, bamboos often invade adjacent forests and disturb natural vegetation. Proper management and conservation strategies, therefore, are required for the maintenance of rural landscape.
