This study is designed to delve into the measuring systems of different periods so as to help with more exact representations of cultures of different periods. The basis of the measuring system in china stems from the huangjong (Huangzhong : the yellow bell) of the period of Huangdi, the length of the bell being the width of 90 black millet grains. Do (Du : width) ; 1 bun=the width of one black millet grain, 1 Chon=10 Buns, 1 Chuk=10 Chons, 1 Jang=10 Cheoks, 1 In=10 Jangs. Ryang (Lyang : volume) ; 1 Yak=the weight of 1,200 grains in the yellow bell, 1 Hab=2 Yaks, 1Seung=10 habs, 1 Du=10 Seungs, 1 Gok=10 Dus. Hyung (Hung : weight) ; 12 Jus=the weight of 1 Yak, 1Yang=24 Jus are equal 1 Hab in weight, 1 Geun=16 Ryangs, 1 Jo=30 Geuns, 1 Seo=4 Jo. In the era of Eun (In) it was decided that the 9-chon length of the Yellowbell shall be 1 Cheok. The Cheok of Ju was set at 4/5 of the length of the yellow bell. The Cheok of Ju breaks into Yongjocheok, Joryegicheok, Pogeumcheok. Yongjocheok, arising from Rohbancheok of the Ju period, is part of Gokcheok also used as a measuring tool for wooden works. The Han cheok has the same length as the yellow bell. The Sang Cheok is 4/5 of the length of the yellow bell. The Tang Cheok was originally the same as the Sang cheok but became longer and longer to be the Long cheok (31.3cm). The length-measuring system used in the three-nation era of Korea includes the gijeom cheil (35.52cm), Ju cheok (25.45cm), sunje Cheok (23.5cm), the Long Tang Cehok (29.706 cm), making 10 Bun 1 Chon and 10 Chon 1 Cheok. The volume-measuring system(Seung) was 198.81 ㎤ before 681 BC in the shilla Dynasty and was 596.42 ㎤ after that. In the seventh year of Kng Munjong of the Koryo dynasty the standard measuring system with the Long Tang Cheok as its basis was adopted, and the standard volume-measuring tools were used under the name of Migok, Daesodugok, Mijangdu, (29.706 cm), making 10 Bun 1 Chon and 10 Chon 1 Cheok. The volume-measuring system(Seung) was 198.81㎤ before 681 BC in the shilla dynasty and was 596.42 ㎤ after that. In the seventh year of King Munjong of the Koryo dynasty the standard measuring system with the Long Tang Cheok as its basis was adopted, and the standard volume-measuring tools were used under the name of Migok, Daesodugok, Kijangdu, Habseung and gokseok. The 1 Seung volumes of theses toolas were 596,447,927 and 1053㎤, respectively. were called Migok, Daesodugok, Mijangdu, Habseung and Gokseok, being respectively 596,447,927, 1053 ㎤, respectively. In the Chosun Dynasty the length of the Yeongjocheos was 27.6 cm or 31.220 in the Sejong era, 29.8 from Heonjong through Gojong, and 30.3 cm after the 6th year of King Kwangmu, and the volume of Du(Mal) also changed like 4.121 or 5.964, 5.187, 23.08 $\ell$, and the 1-Jeonjung also changed like 2.66 or bout 4, 3.45, 3.75 in line with the changes of the length system.

This study is examine the scales applied to buildings in the age of Unified Silla through construction sites excavated and its results are as follows; First, scales used in the age of Unified Silla were varied like Jucheok, Dangcheok and Hancheok, but it was generally accepted that Dangcheok was used in Yeongjocheok Since it was found that the scales applied to Dabotap at the Bulguksa temple and main building of the Gameunsa temple belonged to Goguryeo, Yeongjocheok scale used early in the age of Unified Silla was transitional and it was thought that Goguryeocheok and Dangcheok were used togethar. Second, according to actual rulers in Korea, china and Japan, the length of Dangcheok(ruler used in Chinese Tang era) mostly belonged to the extent of $29.25cm\;{\sim}\;30.5cm$(central value: 29,71cm). Third, plane features of main building of temple are assumed that it had five rooms in front compartment until the 7th century and then it was diversified to three, five and seven compartment. The size of compartment was same in the scale of front Eokan and Hyeopkan until late 7th century, but since then the dimension of Eokan tended to be wider than Hyeopkan. It was judged that the front Eokan used triple scales like 9, 12, 15, 18 cheok. Fourth, the length of residential structures was 17.5cheok${\sim}$36cheok and Bcheok was commonly used for front side of structure, The length of official structures was 8.4cheok${\sim}$36.3cheok which is similar to residential structures. However it has been confirmed that each of 9cheok, 12cheok, and 15cheok has been used for Eokan and Hyeopkan which gave presumption that triple scales was used for the measure.

Purpose: The purpose of this study is to investigate the change and correlation of pulse energy in Left and Right Chon, Kwan, Cheok during menstruation, especially around menstruation start date. Methods: The subjects of this experiment were 8 healthy women whose menstruation periods are regular. We measured 3D Blood Pressure Pulse Analyzer (3D-MAC) tests before and after menstruation start date. Results: The results were as follows 1. The pulse energy of the Right Chon was significantly decreased and Left Kwan was comparatively increased during the next day of menstruation start date than previous day. 2. There was a negative correlation between Left Kwan and Left Cheok, Right Chon and Right Kwan pulse energy during the previous and menstruation start date. The negative correlation disappeared between Right Chon and Right Kwan at the next day of menstruation start date. Conclusions: The results suggest that Chon, Kwan, Cheok pulse energy changes are related to menstruation and reflect physiological mechanism of menstruating women. Further study will be needed.

This study deals with 8-cheok(ch"), equivalent to 2.4m as the standard scale of architectural module in Korea. 8ch" of Korean module was a unique dimensions compared to other East-Asian architecture. It is inferred that it spread in Joseon Dynasty by the effects of the law which limited the size of buildings and materials according to social rank. 8ch" module was applied to the Palace architecture and the highest grade mansions rather than common and small houses. The application of 8ch" module changed the process of architectural planning, and bred the essential characteristics of Korean architecture in terms of appearance and techniques. In addition, it developed to gain multiformity of composition by combination of other modules.

본 연구에서는 확률기법인 빈도비 모델 (frequency ratio model) 및 지리정보시스템 (Geographic Information System: GIS)의 공간분석기법을 이용하여 강원도 삼척지역 폐탄광 주변의 지반침하 발생 취약지역을 예측하였다. 지반침하에 영향을 주는 요인들을 추출하기 위해 지형도, 지질도, 갱내도, 토지특성도, 시추공 자료, 기 관측된 침하지 자료 등으로부터 공간자료를 구축하였다. GIS 공간분석과 확률기법을 이용하여 지반침하의 주 요인이 되는 8개의 인자를 추출하였고 관측된 침하지역과 8개 인자와의 연관성을 알아보기 위하여 각각의 결정계수($R^2$)를 계산하였다. 빈도비 모델을 적용하여 각인자의 등급별 가중치를 결정한 후, 이를 중첩 분석하여 지반침하 위험 예측도를 작성하였다. 지반침하 위험 예측도를 기존 침하지 위치와 비교 검증한 결과 96.05%의 높은 예측정확도를 나타냈다. 이를 통해 폐탄광 지역에서 GIS와 빈도비 모델을 이용하여 지반침하 위험지역을 정량적으로 예측하는 것이 가능하다고 판단된다.
