Objective : This study was done to clarify ambiguous non-standard weight and measuring units in medical classics. Methods : Using medical classics and research dissertations, we studied the basic definitions of weight and measuring units and the types of non-standard weight and measuring units. We compared non-standard weight and measuring units in the reference literatures, to determine the dose of herbs in the prescriptions. Results : There are three types of units in non-standard weight and measuring units. These are 'Quantity measuring unit', 'Resembrance measuring unit', and 'Eye measuring unit'. And we found historical efforts and progresses for proper ways to convert non-standard weight and measuring units to standard weight and measuring units. Conclusions : This research will be the basic data for the standardization of prescriptions. Additional study was still required for precise weighing and measuring in Korean medicine and pharmacy.

Currently, in Korea, all lengths are written in "meter" unit, and the non-statutory measuring units are banned for use. However, in some fields, traditional measuring units are widely used with necessary modifications, and people in such fields raise varying arguments on conversion to "meter" unit. This research examines traditional measuring units from historical and cultural viewpoints, and provides suggestions on how to improve consistency and standardization for more accurate and effective exchangeof scientific opinions.

This paper aimed to identify the units of measuring scale in Hwangnyongsa temple planning with the published excavation survey reports. Hwangyongsa temple site was planned under Silla Capital's urban planning in 6~7C, its full size was $800{\times}800$, and main temple was $400{\times}515$ of Goguryeo's system of measurement. Main hall was located in the center of Hwangnyongsa temple site, and its location could be seen that there was the arrangement of main temple divided into 3 : 2. Building plan measuring units proved to be 351~356mm and 294~ 296mm by analyzing measured data of remains. Lecture hall and Wooden pagoda were rebuilt by using the ancestors' units of measuring scale again and Bell hall was not planned by Tang's system of measurement in middle of 8C. In this respect, it would be important to have a deliberate attitude and lay down stereotypes on research of the units of measuring scale in ancient architecture.

In this paper we write to the result of measuring human body shape method-ibs-2000 for human body shape measurement. The size measurement units and measuring speed is very inportant to efficiency of human body shape measurement units. By polygonal mirror system, the size measurement units and measuring time can be retrench.

In recent years, it has been variously developed for testing the accuracy of circular motion of NC machine tools, for example Telescoping Ball Bar Method by Bryan, Circular test Method by Knapp and $r^{-{\theta} }$ Method by Tsutsumi etc., but these methods are all 2-dimentional measuring methods on plane. These simple methods of circular motion accuracy test of NC machine tools have been studied by many reserchers as above, but it is not yet settled in the code of measuring methods of motion errors of NC machine tools, because of errors of measuring units and sensors, and also especially the difficulties of centering of measuring units and the spindle of machining center. In this paper, in use of 2 rotary encoders and 1 magnetic type linear scale with resolution of 0.5 .mu. m, it has become possible for measuring of 3 dimentional space motion accuracy.

본 연구에서는 초 중등 학생들의 눈금 읽기 능력과 측정도구의 용도 및 단위에 대한 개념을 조사했다. 초등학생 72명, 중1 학생 69명, 중3 학생 80명의 학생을 대상으로 수행 평가 및 지필 평가를 실시했다. 눈금읽기 능력을 평가하기 위해서 개별 수행 평가를 실시했는데, 학생 개개인은 서류 봉투의 가로 세로 길이, 물의 온도, 물의 부피 등을 실험실에서 주로 사용하는 주어진 측정 도구를 사용하여 측정했다. 측정 도구 및 단위와 관련된 개념을 평가하기 위해서는 그림과 사진이 그려진 질문지를 사용했다. 눈금 읽기 능력 면에서 각 학년마다 적지 않은 측정오차를 내는 학생이 있음이 드러났으며 특히 질량이나 부피 측정의 경우 그 수가 더욱 증가했다. 측정 도구에 대한 학생의 개념 조사 결과 학생들은 물리량 개념이 정확하지가 않아 측정 도구가 측정할 수 있는 물리량을 제대로 지적하지 못했다. 또한 단위에 대해서도 혼동이 있어서 특히 질량, 무게, 부피나 힘의 단위 등을 어려워하고 있음을 알 수 있었다.

In this study, the effects of the power transmission units on the rotational accuracy are investigated experimentally in a hydrostatic spindle. The effects of warm up time, unbalancing and the position of measuring sensor are pre-examined for the determination of measuring conditions. The misalignment of the power transmission units and the vibration excited by the fluctuation of belt are considered as the dominant parameters of error motion. The variation and scatter of run out at the range of 0 to 3,000rpm in rotational speed are appropriated for the camparison of availabilities of the transmission units to precision spin- dles.

Objectives: We aimed to evaluate the effect of geographic units of analysis on measuring geographic variation in medical services utilization. For this purpose, we compared geographic variations in the rates of eight major procedures in administrative units (districts) and new areal units organized based on the actual health care use of the population in Korea. Methods: To compare geographic variation in geographic units of analysis, we calculated the age-sex standardized rates of eight major procedures (coronary artery bypass graft surgery, percutaneous transluminal coronary angioplasty, surgery after hip fracture, knee-replacement surgery, caesarean section, hysterectomy, computed tomography scan, and magnetic resonance imaging scan) from the National Health Insurance database in Korea for the 2013 period. Using the coefficient of variation, the extremal quotient, and the systematic component of variation, we measured geographic variation for these eight procedures in districts and new areal units. Results: Compared with districts, new areal units showed a reduction in geographic variation. Extremal quotients and inter-decile ratios for the eight procedures were lower in new areal units. While the coefficient of variation was lower for most procedures in new areal units, the pattern of change of the systematic component of variation between districts and new areal units differed among procedures. Conclusions: Geographic variation in medical service utilization could vary according to the geographic unit of analysis. To determine how geographic characteristics such as population size and number of geographic units affect geographic variation, further studies are needed.

In this treatise, the kinds of main dishes and the frequency of them, and the materials, the variation of recipe, the measuring units, the cooking utensils, and the measuring terms, which used for making main foods were studied from the books published from 1670 to 1943 in Korea. 1. Main dishes were classified as Bap, Zook: Am-Zook, Mee-Um: Yue-Yi: Won-Mi, Guck-Soo: Naeng-Myun, Man-Doo: Duck-Guk: Soo-Jae-Bee. 2. There were 115 kinds of main dishes including 21 kinds of Bap and Yack-Bap, and 34 kinds of Zook and Am-Zook, 11 kinds of Mee-Um, Yue-Yi and Won-Mi, and 21 kinds of Man-Doo, Duck-Guk and Soo-Jae-Bee. 3. There were 41 kinds of measuring units used for making main dishes including 17 kinds of volume units, 3 kinds of weight units, 14 kinds of quantity units, 4 kinds of units for length, thickness, and 3 kinds of the others. 4. There were 62 kinds of cooking utensils among which Ssot (iron-pot) was the most widely used, but nowadays the most of them were rarely used due to automatization and mechanization of living tools. 5. All cooking terms were 148 kinds including 52 kinds of terms for the preparing process, 24 kinds of terms for the mixing process, 30 kinds of terms for the making-shape process, 18 kinds of terms for the heating process, 16 kinds of terms for the chopping process, and 8 kinds of terms for the setting process.

Investigators use either Euclidean distance or volume of a simplex defined composed of data points as agreement index to measure chance-corrected agreement among observers for multivariate interval data. The agreement coefficient proposed by Um(2004) is based on a volume of a simplex and does not depend on the variables' measuring units. We consider a comparison of Um(2004)'s agreement coefficient with others based on two unit-free distance measures, Pearson distance and Mahalanobis distance. Comparison among them is made using hypothetical data set.
