Objectives : Ryodoraku, which is a physiological function test using electric current, is closely related to skin sympathetic tone. Pulse analysis is known to reflect cardiovascular reactivity. Refer to the previous researches Ryodoraku and pulse analysis have value as tools for diagnosing respiratory diseases. In this study we examined the diagnostic values of Ryodoraku and pulse analysis for respiratory disease patients. Methods : For this study. we conducted Ryodoraku and pulse analysis on 114 people, including 83 respiratory disease outpatients and 31 volunteers who did not have any respiratory symptoms or disease history. The respiratory patients were divided into three subgroups according to their symptoms: rhinorrhea group, cough-sputum group and wheezing-dyspnea group. Then we compared the disease groups with the control group. Results : When all experimental groups were compared with the control group, mean Ryodoraku was significantly lower. Mean H2, mean H3 and mean H6 were significantly lower in the rhinorrhea group (P<0.05), all the test results of Ryodoraku were evidently lower in the cough-sputum group (P<0.01), and most results of Ryodoraku were evidently lower in the wheezing-dyspnea group except H1 (P<0.01). Compared with the control group on pulse analysis, mean YP+/YP- was significantly lower in the wheezing-dyspnea group (P<0.05). Conclusion : Ryodoraku and pulse analysis were found to have a high value as quantitative diagnosis tools reflecting individuals' weakness and firmness. Nevertheless, more research is needed to find the further values.

Objectives : Ryodoraku is a physiological function test using electric current, and is closely related to skin sympathetic tone. Pulse analysis is known to reflect cardiovascular reactivity. There has been no report on the correlation between ryodoraku and pulse analysis in respiratory diseases. The present study examined the diagnostic values of ryodoraku and pulse analysis for respiratory disease patients Methods : For this study, we conducted ryodoraku and pulse analysis in 103 people including 79 respiratory disease outpatients who visited the $5^{th}$ Internal Department of the Oriental Medicine Hospital of Kyung Hee University during the period from January 1, 2003 to July 25, 2006, and 24 volunteers who did not have any respiratory symptoms or disease history. The respiratory disease patients were divided into five sub-groups according to their symptom: cough-sputum group, wheezing-dyspnea group ' nasal symptoms group. cold-prone group, and fatigue prone group. We compared the disease groups with the control group in six items as follows : mean ryodoraku, mean H1, mean elastic index, the percentage of those with mean ryodoraku below $40{\mu}A$, the percentage of those with HI beyond the physiological range, and the ratio of left : right of elastic index Results and Conclusions : Ryodoraku and pulse analysis were found to have a high value as quantitative diagnosis tools reflecting individuals' weakness and firmness. The results of this research suggest that ryodoraku and pulse analysis have value as tools for diagnosing respiratory diseases.

The Standardization of terms in The Pulse studies(脈學) is a need for development of learning. This study, for the correction of existing misused terms in The Pulse studies, we study on modernly and objectively the terms in The Pulse studies. By a focus of ${\ulcorner}$The Pulse Studies of Bin-Ho(瀕湖脈學)${\lrcorner}$, we studies on the new classification of pulse condition. The error of a existing technical books on Pulse studies begin that the classification of pulse condition is not establish a Standardization. For the correction of existing misused terms in The Pulse studies, we study on the pulse condition is expressed objectively a blood vessel that it is a subject of pulse condition. The expression of blood vessel contain a depth of blood vessel, a speed of pulsation, a curve of blood vessel, thickness of blood vessel, a diameter of blood vessel in expand and contract of blood vessel, a interval in expand and contract of blood vessel, a distinctness on a boundary of blood vessel, a speed of blood flow in blood vessel, a volume of blood flow in blood vessel, a condition of blood in blood vessel, a propelling power of blood vessel. These is standard of the new classification of pulse condition.

These days it is becoming more and more common to find electronic medical screening systems installed in Oriental hospitals and clinics. This is a relatively new development for the practice of traditional Oriental medicine. Specifically, Pulse detection machines are being utilized in order to help determine a patient's disease scientifically. However, identifying and diagnosing the specific disease correctly for each patient is still very difficult in Oriental medicine. The intention of this paper is to propose a solution which uses two separate Electronic systems working together to produce a better likelihood of finding the correct diagnosis for each patient. It is proposed that an EMR intelligent electronic chart system be developed and employed, which would utilize both Pulse wave system and a tongue detection system at the same time, in order to solve the problem. Computer simulation results have proven to show that EMR systems used in hospitals and clinics are more efficient and yield a more accurate diagnosis than traditional methods.

The purpose of this study is to select the major pulse indicators and evaluate their significance in discriminating the subtypes of Pattern Identifications (PI) from stroke patients. Decision tree analysis was carried out using clinical data collected from 835 stroke patients with the same subtypes diagnosed identically by two experts with more than 3 year clinical experiences. Among the 10 pulse indicators, 6 major pulse indicators (slow, rapid, strong, weak, slippery, and fine pulse) were selected by decision tree analysis. The accumulated distributions of six pulse indicators in each PI showed that strong was major pulse indicator in Fire-Heat pattern, slippery in Dampness Phlegm pattern, weak in Qi Deficiency pattern. But there were two major combinations in Yin deficiency pattern, weak or fine with rapid pulse and weak or fine without rapid pulse. Therefore, it is suggested that 6 pulse indicators can be used for discrimination of PI in stroke patients, though the combination studies between these pulse indicators and the other PI indicators are left for further study.

This study aims to develop a system for diagnosing pulse and disease conditions based on oriental medical classics to collect objective quantitative information in the traditional pulse examination environment that uses fingers. For this purpose, the study suggested a thimble-type sensor unit as the most appropriate pulse analyzer and proposed a traditional method to measure the pulse pressure wave on the spots of cheok, gwan and chon by installing the pulse analyzer on the forefinger, middle finger and medical finger. Then, it was interpretively found that this pulse analyzer enables us to objectively recognize 28 pulses defined in Oriental medical classics including the yukjo pulse, described as the buchimjisak-heosil pulse, and the hong, yoo, hyeok and san pulses. Finally, the study proposed a method to extract key parameters essential to pulse condition diagnosis from the pulse pressure wave measured by this pulse analyzer.

배경 : 체질의학에서 진단의 중요성에도 불구하고 팔체질의학의 맥진의 신뢰성에 대한 과거 연구가 거의 없었다. 목적 : 본 예비연구는 팔체질의학의 맥진에 대한 진단자 간의 신뢰성 및 진단자 내의 신뢰성을 검사하기 위함이다. 재료 및 방법 : 팔체질의학을 이용한 진료 경력이 3년 내지 5년 되는 한의사 두 명이 실험에 참여하였다. 31명의 건강한 대학생들의 팔체질을 맥진을 통해 진단하고 그 결과를 확신도와 함께 각각 기록하도록 하였으며 이 중 5명은 각각 진단자로부터 3회씩 진단을 받도록 하였다. 그 결과를 분석하여 진단자 간의 신뢰성과 진단자 내의 신뢰성을 검사하였다. 아울러 진단에 대한 확신도와 결과와의 상관성이 있는지도 조사하였다. 대상자와 진단자는 서로를 알 수 없도록 가리개를 하고 실험을 진행하였다. 결과 : 진단자 간의 일치도는 35.7%였으며 카파 계수는 0.232로 보통 이하 수준인 것으로 나타났다. 진단자 내 일치도는 진단자 별로 각각 89%, 66.83%로 나타났다. 다만 두 진단자 사이의 결과가 일치하는 경우 불일치하는 경우보다 진단자의 확신도가 높은 것으로 드러났다 결론 : 본 연구에서는 팔체질의학의 맥진의 진단자 간, 진단자 내의 신뢰성이 비교적 낮은 것으로 나타났다. 이는 진단의 변수가 많고 진단자의 숙련도나 대표성의 문제 등 여러 가지 요소들로 인한 결과로 파악된다. 팔체질의학의 진단자 간, 진단자 내의 신뢰성에 대한 향후 연구가 절실히 요구된다.
