Objectives : To obtain pulse information, oriental medical doctors usually use the three finger pulse diagnosis method. Although the diagnostic positions are very important, the exact positions are not known because of the uncertain conversion of measures of length (bun, chon, chuk) and misunderstanding of the related concepts of oriental medicine. In this study, we proposed relative positions for the detection of three pulses with a pulse analyzer. Methods : The proposal was made based mainly on several literature reviews, especially the original texts, and the examination of anthropometric characteristics of 78 individuals. Results : The Kwan is the spot where the radial pulse can be felt well near the eminent head of the radius at wrist, high bone. The position of Chon should be apart from Kwan by 6/10 distance between the high bone and wrist joint of each individual. Finally, the position of Chuk is apart from Kwan by 6.5/100 distance between the high bone and the elbow joint of each individual. Conclusions : Adapting those proposed positions for measuring three pulses can provide more consistent information to what an oriental doctor obtains than a pulse analyzer applied to other positions.

Objectives : The purpose of this study is to observe the effects of $Sa-Am$ lung sedating acupuncture (LS) on wrist pulse changes in healthy participants. Method : Forty healthy subjects participated in this study, and were divided into an acupuncture group and controlled group. Using a three-dimensional pulse imaging system (DMP-3000), wrist pulse was measured before, immediately after, 30 minutes after and 60 minutes after acupuncture in the acupuncture group, with the rest in controlled group. Sixteen parameters between the acupuncture group and the controlled group were analyzed at Cun, Guan and Chi in each time. Result : After LS acupuncture, wrist pulse sixteen parameters were changed significantly according to the time at each measuring region. 1. Heart rate significantly decreased in immediately after, 30 minutes after and 60 minutes after, Pulse period significantly increased in 30 minutes after and 60 minutes after. 2. T4 didn't significantly changed, T-T4 significantly increased in immediately after, 30 minutes after and 60 minutes after. T4/T, T4/(T-T4), T1/T, T5/T significantly decreased in immediately after, 30 minutes after and 60 minutes after. (T-T4)/T significantly decreased in immediately after, 30 minutes after and 60 minutes after. T5 significantly increased in 30 minutes after and 60 minutes after. 3. Modulus of elasticity significantly decreased in left Cun 60 minutes after, significantly increased in left Chi 30 minutes after. 4. Variance of Amplitude significantly increased in right Guan 60 minutes after. 5. Area of pulse significantly increased in left Cun 60 minutes after, left Chi 30 minutes after and right Cun 60 minutes after. Systolic pulse area significantly decreased left Chi 30 minutes after, right Cun immediately after, 30 minutes after and 60 minutes after, right Guan in immediately after. 6. Energy/min significantly decreased in left Chi 60 minutes after and right Cun immediately after. EIx significantly decreased in right Cun immediately after. 7. In both sides Cun, Guan, Chi wrist pulse, a lot of significant changes in right Cun and left Chi appeared, and then followed by the left Cun, right Guan. Conclusion : This study analyzed that the correlation between LS acupuncture and radial pulse(cun, guan, chi) is considered to be meaningful, hereafter clinical studies on this are needed.

Pulse-feeling took its origin from making a diagnosis along meridians in the course of discovering and forming meridians and for a long time its meaning was mixed with meridians in the course of recognizing "The Pulse" then was separated from meridians in the early days of Western Han Dynasty. Ancient pulse-feeling methods are pulse-feeling method by the twelve regular meridians, pulse-feeling method by three regions and nine modes, pulse-feeling method by Inyeong(人迎) and Chon-gu(寸口), etc. Pulse-feeling was changed in proportion to diagnostic purpose and method of treating and if method and region of pulse-feeling is arranged, we will infer correlation between meridians and pulse-feeling and will infer transitional system of past pulse-feeling and will forecast transition of future pulse-feeling. As the result that I study the transition of the above three pulse-feeling methods of meridians diagnosis: 1. Three pulse-feeling methods of meridians diagnosis flowed into diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ and were changed into diagnostic method being fit for use of five Su points, The Front-Mo points and Back-Su points that grasp the pathology of mutual internal organs and treat the disease. 2. Today it is suggesting the transition of another pulse-feeling method that do not apply diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ to 19C Sasang(四象) Constitutional Medicine or 20C Eight Constitutional Medicine.

Background and Purpose: Feeling the pulse is based on the pulse condition and alteration to observe the condition of the human body's health and by using a healthy person's pulse as a standard we are able to analyze the patient's pulse to find the attacked channel and collateral, viscera and bowels and understand the pathology such as diseases caused by exogenous evil, disorder of internal organs, and seven modes of emotions. Observing the color and shade of the patient's face, listening carefully to the sound of the patient, and feeling the pulse are methods in accordance with Su Wen 'Plain Questions', 'The Classic on Difficulty' (5th century B.C. Bianque), 'The Classic of Sphymology' (280 A.D. Wang Xi), 'Pulse Formulas' (1189 A.D. Cui Jiayan), and is systematically edited for those who have started studying to easily reach the profound state. Therefore, 'The Elementary Course for Medicine' has been used from ancient times as the textbook for diagnostics. Methods: In this Study, we will inspect commonly used pulse feeling methods, the inch, bar, cubit thesis, the viscera and bowels thesis from The Elementary Course for Medicine and inquire the difference of the text from 'Plain Questions of Huangdi's Internal Classic', 'Treatise on Febrile Diseases', 'Classic on Difficulty'. Results and Conclusion: 1. In 'The Elementary Course for Medicine' the site of the wrist along the pulsation of the radial artery is divided into inch, bar, cubit and has defined the inch, bar, cubit crossways. 2. In 'The Elementary Course of Medicine' the inch, bar, cubit for the left hand and right hand is subjected to each viscera and bowel. By assigning the left hand's inch, bar, cubit to the cardial orb, the hepatic orb, the renal orb, and the right hand's inch, bar, cubit to the pulmonic orb, the splenic orb, the vital gate it has been able to feel the pulse for each viscera and bowel by using the interpromoting and interacting relation of the five evolutive phases.

The study aims to measure and analyze the thickness and depth of blood vessel on the pulse diagnosis locations and the blood velocity through the use of ultrasonic waves (LOGIQ5PRO, GE Medical, U.S.) in order to understand the structural difference of pulse diagnosis locations. The subjects included 44 healthy men and women(22.28${\pm}$2.62 age) considered normal in terms of Body Mass Index(BMI). The thickness and depth of the blood vessel and the blood velocity were measured three times on CHON, KWAN and CHUCK to obtain the average value. Results showed there is a statistically significant difference among the variables measured on CHON, KWAN and CHUCK. A difference according to gender was also observed. This explains why an oriental medical doctor can tell the difference in pulses depending on the location of CHON, KWAN and CHUCK. In addition, the difference in pressure between CHON and KWAN was higher than that in pressure between KWAN and CHUCK. The findings explain why oriental medical doctors take pulses by dividing CHON, KWAN and CHUCK in the short length of the three fingers. It can be used to develop a pulse diagnosis device enabling accurate measurement according to the characteristics of blood vessel structure based on where the pulse is taken. Furthermore, the results can be used as basic data for the development of a pulse diagnosis simulator.

Pulse diagnosis is a central diagnosis method used in traditional Oriental medicine. To standardize and modernize the pulse diagnosis method, it is essential to develop an instrument-based reinterpretation of the clinically used pulse images in terms of the physical quantities such as the strength, period, width, length, and depth of the pulse. As a step towards such standardization, we conducted a clinical study on the floating/sinking pulses based on an automated palpation instrument (3D-MAC, Daeyo Medi, Korea) for 213 female subjects in their 20s and 174 female subjects in their 60s. The floating/sinking pulses are the two representative pulse images depending only on the depth of the pulse, and can be conveniently scaled by the coefficient of the floating-sinking pulse ($C_{fs}{\in}(0,1)$), which represents how strong one should apply the hold-down pressure to obtain the maximal pulse strength. As a result, primarily we found that it tends to appear more floating-like pulse ($C_{fs}{\rightarrow}0$) at Gwan and more sinking-like pulse ($C_{fs}{\rightarrow}1$) at Cheek, at both age groups and at both wrists. This result is consistent with a previous study on the geometrical structure of the blood vessel by an ultrasonograph. Second, the pulse tends to be more sinking-like in the age group of 60s than 20s. Finally, the pulses at the right palpation positions were found to be more sinking-like than the left, at both age groups.
