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.

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.

한국 디자인사의 일반적 접근 경향은 한국의 정치, 경제, 사회적 측면에서 근대화 문제와 관련된 거대 담론에 주로 연구 초점을 맞추어 왔다. 근대화 논의에는, 그러나, 자본주의적 생산양식의 자장 안에서 전개되는 공적, 제도적, 권력적 근대화 외에 일상적인 삶의 양식으로 발현되는 사적, 개인적, 문화적 근대화라는 두 측면이 내재되어 있다. 특히, 현실사회주의의 실패 이후 후자의 관점이 역사학계를 비롯한 제 분야에서 새로운 대안으로 부각되고 있음에도 불구하고, 한국 디자인 역사 연구가들의 근대적 디자인 현상에 대한 역사 인식은 일상적 현실 안에 존재하는 ‘아래로부터의 역사’이기보다는 현실 밖에 담론의 차원으로 존재하는 ‘위로부터의 역사’인 경우가 많았다. 이와 같은 엘리트 중심의 역사인식 틀에 균형감을 부여하기 위해서는 보통 사람들의 자발적인 디자인 행위로 구현된 일상적 삶의 표상들을 연구대상으로 삼음으로써 한국 디자인의 역사를 일상 문화적인 시각을 통해 아래로부터 재구성하는 작업이 요구된다. 이 물음에 대한 한 가지 접근방법은 지순한 한국 어머니 상의 전형인 올해 87세의 양갑조 할머니가 일생동안 제작해 온 규방 공예품을 문화사적 시각으로 읽어내는 일이다. 한국 디자인사의 거시적 담론 속에 묻혀버린 민초들의 일사적인 삶의 구적들에 대한 역사적 반추 작업을 통해 작지만 다층적인 한국 디자인의 의미소들을 발굴해 냄으로써 문화사로서의 한국 디자인의 역사적 전망을 가늠해 보는 전기를 마련하고자 한다.

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.

우리 나라 대나무의 시.공간적 분포에 영향을 미친 요인을 분석하였다. 참대속부터 산죽속에 이르는 모든 대나무의 분포 북한계선은 백령도 - 장수산 - 멸악산 - 용문산 - 명지산 - 추애산 - 후탕 - 묘향산 - 명천에 이르는 선 남쪽이다. 화석에 따르면 한반도의 대나무는 지질시대부터 분포하였고, 고문헌에 의하면 대나무는 조선시대에 의식주 등의 생활재료로 널리 사용되었다. 조선 초기부터 일제 때까지의 고문헌들을 기초로 한 왕대와 이대 등 군현별 시대적 분포지 복원에 따르면 대나무는 시대에 따라 분포지가 변화하였다. 대나무의 시.공간적 분포역 변화는 기후변화 등 자연적 요인과 함께 재배와 이식 등 인위적인 영향에 의한 것이다. 최근 국내 죽세산업이 침체되면서 대 나무숲이 다른 용도로 바뀌어 사라지거나, 반대로 방치되어 확산되면서 자연식생을 교란시키므로 농촌경관의 유지를 위하여 관리와 보전 대책이 요구된다.
