Objective : The region, observation period, figuration of pulse, pulse frequency, process of diagnosis and related diagnostic methods in traditional pediatric pulse diagnosis were studied in this article. Method : The articles related to traditional pediatric pulse diagnosis in Traditional medical classics, and analysis to the characteristics of it was done, then lastly, the principle of pulse manifestation and the meaning of application to modern times were considered. Result & Conclusion : It is difficult to catch the figuration of pediatric pulse because of dynamic change of body conditions, fast heartbeat and narrow region of pulse. Therefore, the pulse diagnosis appropriated for children have been developed and combined with the special diagnosis methods, for example, palpation of forehead and observation of index finger. The traditional pediatric pulse diagnosis is done with just one finger palpation in the period of 3 to 5 years old to identify the speed, length, size and height of pulse. The standard average of pulse frequency is 7~8 par breath in the period of 3 to 5 years old according to traditional medical classic.

Pulse diagnosis that is one of important examination methods in traditional oriental medicine has been investigated for the standardization in many ways. Pulse analyzer device and clinical studies have been tried for this purpose. Additionally, literature study has significance for this standardization. In this study, we analyzed pulse types in literatures from the viewpoint of physics. We refered to Maijing, Maijue, siyanjuyao, Binhumaixue, Yixuerumen, zhenjiazhengyan. We established some physical factors for analysis. This factors that can be detected through pulse analyzer are depth, speed, power, width, and length. In this study, we defined 18 kinds of pulse types among 28 total types by physical factors. Furthermore, 6 kinds of pulse types were classified as basic pulse from these. The results of this study will improve the pulse analyzer to detect these pulse types.

Objectives : The purpose of this study is to research the relations between the Renying pulse and Qikou pulse diagnosis(人迎氣口脈診法) and the Chong vessel(衝脈) based on Yin and Yang(陰陽). Methods : We set up locations of the Renying pulse and the Qikou pulse as ST9(Renying pulse) and LU9(Qikou pulse) respectively. Several medical texts and papers were examined from the ancient to modern periods, in which the relations between the Renying and Qikou pulse diagnosis(人迎氣口脈診法) and the Chong vessel(衝脈) were analyzed based on Yin and Yang(陰陽). Results & Conclusions : The Chong vessel(衝脈) goes around the whole body and its dysfuction can be determined at pulsating sites. Also the Chong vessel(衝脈) supplies Source Qi(原氣) to the Stomach where it generates Nutrient Qi(營氣) and Defense Qi (衛氣). Due to the Lung's function that balances Nutrient Qi(營氣) and Defense Qi(衛氣), the balance between Yin and Yang is accomplished. This Yin-Yang balance can be confirmed through pulse diagnosis of the Renying pulse and Qikou pulse(人迎氣口脈診法).

The pulse diagnosis is an important and universally used method in Oriental Medicine. Since the traditional method of palpating the pulse relies on the subjective sense in the fingers of an Oriental Medical Doctor(OMD), there has been continued need for more objective method for pulse diagnosis. Recently, various pulse analyzers have been developed to meet such objective palpation and interpretation. However, most of these attempts were not successful to replace OMD's own palpation by fingers. To improve the performance of the pulse analyzers, one should develop machine-appropriate interpretations for the pulse images in the literature, in addition to the improvement in the repeatability and reproducibility. One of such widely-used pulse images to be interpreted is the floating and sinking pulse. The floating and sinking pulses are the two representative pulse images informing us how strong pressure one should apply to obtain the maximal pulse strength. A previous study suggested a convenient and unified measure for the floating and sinking pulses by defining the coefficient of the floating-sinking pulse(CFS). We found the original definition of the CFS could be erroneous under some situations. To improve the performance, we introduce new CFS algorithm for determining the floating and sinking pulse with a pulse analyzers(3-D MAC). To test the performance of the newly suggested algorithm, we conducted a clinical study comparing the agreement ratio with the floating and sinking pulse diagnosis by the OMDs. We found that, among the subjects who are diagnosed with having either the floating pulse or sinking pulse, the new CFS algorithm showed 55.3% diagnosis rate and 73.0% concordance rate, which are about 3% and 6% improvement in the diagnosis rate and agreement rate, respectively, compared to the original CFS algorithm.

1. Objective Pulse diagnosis is generally applied to Traditional Oriental Medicine but not to Sasang Constitution diagnosis. Recently new pulse analyzer using array piezoresistive sensor and multi-channel robot arm developed. It reflects Oriental Medical Doctors' diagnostic processes, and its reproducibility test was done at Korea Institute of Oriental Medicine. We performed this study to set parameters diagnosing Sasang Constitution. 2. Methods One hundred thirty three subjects participated in this study. They are healty and approved this study. Before being tested with pulse analyzer, they had interview with Sasang Constitution Specialist to diagnose their Sasang Constitution. We established some useful parameters from parameters of pulse analyzer according to the Original Texts of Oriental Medicine and clinical experiences to analyze with clinical data of this study. 3. Results (I) There is a significant difference in pre-dicrotic notch time among all parameters of pulse analyzer in Sasang Constitution groups(P=0.047). (2) There is a significant difference in maximum pulse pressure in 33 to 48 year Sasang Constitution groups(P=0.010). (3) There is a significant difference in frequency width in 17 to 32 year Sasang Constitution groups(P=0.002). (4) There is a significant difference in CFS value in groups which OMD diagnoses; Floating & Sinking pulse(P=0.020). (5) There is a significant difference in pulse rate in groups which OMD diagnoses; Rapid & Slow pulse(P=0.000). (6) There is a significant difference in maximum pulse pressure in groups which OMD diagnoses; Deficient & Solid pulse(P=0.000). 4. Conclusions Analyzing parameters in each Sasang Constitution group, we found it shows significant difference in maximum pulse pressure and corresponding tendency in coefficient of floating & sinking pulse with theories of Sasang Consti-tutional Medicine. As we accumulate more clinical data, we will establish algorithm to diagnose Sasang Constitution using a pulse analyzer.

Pulse diagnosis refers to the process of diagnosing a patient by feeling an artery on the wrist based on the shape that the pulse take s while the hold-down pressure increase. The styloid process artery on the wrist is usually felt, and the pulse is taken on Chon, Gwan and Cheok using three fingers. This study is to examine the structural difference in the location of pulse diagnosis by measuring and analyzing blood diameter, blood depth, and blood flow velocity of the location of pulse diagnosis by using ultrasonic wave (VOLUSION730 PRO, GE Medical, U.S.A). This study also attempted to grasp whether the characteristics of blood vessels differ depending on Body Mass Index (BMI) and analyzed their correlation with Oriental medical pulse diagnosis. The male subjects without cardiovascular diseases were divided into the normal BMI group, the underweight group and the overweight group and 10 people of each group were measured, Blood depth, blood diameter and blood flow velocity at the location of pulse diagnosis (Chon, Gwan, Cheok) of the wrists of left and right hands were measured and the pulse wave was measured by using pulse diagnosis instrument (3-D Mac, DaeyoMedi, Korea).The results of this study showed that the characteristics of blood vessels differ depending on the degrees of obesity, and the characteristics of floating pulse and sinking pulse of Oriental medical pulses were related to the degrees of obesity. This shows that the characteristics of the blood vessels of subjects and BMI information are the major indicators for diagnosis and are the matters that must always be considered when developing the algorithm of pulse diagnosis.

Pulse diagnosis has been highly valued in many East Asian medical books, since "Huangdaineijing(黃帝內經)" published. Gigoo-inyoung pulse method(氣口人迎脈法) is one of the four pulse diagnostic methods originally written in"Huangdaineijing(黃帝內經)". At the late 3rd century, "Maijing(脈經)" redefined the positions of Gigoo-inyoung pulse(氣口人迎脈). According to "Maijing(脈經)", both spots were 1fen(分) in front of guan(關) but Gigoo on the right hand and Inyoung on the left hand. At the middle of 13th century, "Maekgyolejijangbyungsikdoseol(脈訣指掌病式圖說)" had detailed view points about the manner of reading Gigoo-inyoung pulse. "Maekgyolejijangbyungsikdoseol(脈訣指掌病式圖說)" explained clearly the position of 1fen(分) in front of guan(關) by sketch of wrist. The location indicated the border of cun(寸) and guan(關). It also explained clearly corresponding certain cun-guan-chi(寸關尺) with Gigoo-inyoung pulse by sketch. "Euihackipmoon(醫學入門)" is a comprehensive book on medicine written by Lee-Cheon(李梴) in Ming(明) dynasty. In this book, pulse diagnosis is the most emphasized method among the four techniques of diagnosis(四診). Furthermore, it introduces detailed information about Gigoo-inyoung pulse method(氣口人迎脈法) in "Gigoo-inyoungmaekgyole(氣口人迎脈訣)". Lee-Cheon concured in the theory of "Yeongruegumbang(永類鈐方)" and "Maekgyolejijangbyungsikdoseol(脈訣指掌病式圖說)" and put a short essay about Gigoo-inyoung pulse named "Gigoo-inyoungmaekgyole(氣口人迎脈訣)" quoted from the two books. Therefore, throughout many chapters of "Euihackipmoon(醫學入門)", Gigoo-inyoung pulse is used in order to distinguish internal damage(內傷) and external contraction(外感). "Maekgyolejijangbyungsikdoseol(脈訣指掌病式圖說)" and "Euihackipmoon(醫學入門)" understood Gigoo-inyoung pulse commonly by corresponding certain cun-guan-chi(寸關尺) with Gigoo-inyoung pulse. Therefrom, Gigoo-inyoung pulse can distinguish seven emotions(七情) of internal damage(內傷) or six excesses(六淫) of external contraction(外感).

In the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse are the arterial pulsation position of the Lung Channel of Hand-Taeuem(手太陰) and the Stomach Channel of Foot-Yangmyeong(足陽明). At the pulses we can examine the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽), the deficiency and excess of the diseases, whether the disease is in Uem-Channel(陰經) or Yang-Channel (陽經), whether the disease is internel injury or externel injury. In the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse are in front of the Right-Kwan(右關) and the Left-Kwan(左關) the distance of 1 Pun(分) because of completion of the Chon-Ku-Pulse-Taking(寸口脈診). The purpose of examnation is same to . In the Kwan-Pulse(關脈) doesn't have the position. It has only the role of a gateway of the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽). And it is same to role of the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse in . So we can think that the Kwan-Pulse(關脈) in and the Ki-Gu(氣口) pulse and the Yin-Yeong(人迎) pulse in are the same thing. And we must have the different standard when examine the condition of Sam-Cho(三焦) and the circulation of Ki-Hyeol(氣血), the balance of Uem-Yang(陰陽) because the position of the Kwan-Pulse(關脈) came out after the time of .

Objectives : Informations on pulse diagnosis in literature are based on diagnosing pulse waveforms on supine posture. However, today's pulse waveforms are measured on various postures for the convenience of patients or doctors. For objective measurement, the effect of posture on the pulse waveforms should be considered. The objective of this study was to find posture-related changes in the radial pulse waveforms. Methods : We used an instrument, DMP-3000(DAEYOMEDI Co., Ansan, Korea), measuring radial pulse waveforms noninvasively by tonometric method. 25 male subjects participated in the trial. Before measuring radial pulse waveforms subjects had rest for 5 min. The pulse waveforms were measured on the left wrist. Each subject underwent this course on the supine, sitting, and standing posture. We analyzed pulse waveforms with Height-parameters, Time-parameters, Energy, and Elastic rate. Results : Height-parameters(h1~h5) on the supine posture were bigger than those on the sitting and standing posture. In case of Time-parameters, the parameters making up systolic time decrease in order of on standing, sitting, and supine position. However, systolic time and diastolic time didn't have any changes. Energy of pulse was the biggest on supine posture and Elastic rate on standing posture. Conclusions : In this study we found that posture changes affect radial pulse waveforms. For quantification of the changes, more trials should be done. After analyzing much data we might apply parameters of pulse waveforms changed by posture. Also, we might diagnose special disease with properties of pulse waveforms by posture.

In this study the skin care system was designed and tested by introducing V-IPL(Variable-Intense Pulse Light) methods that allow various skin treatments. The discharge method, a new method of switching on the flash lamp sequentially according to the lesions, was used. Pulse shape control is implemented in the system using the conventional LC variable method and the switching method control method of the switching element. As a result, the pulse width could be varied up to 1[㎛] by using a microprocessor, and by turning on the flash lamp sequentially along the lesions the depth and width, the pulse shape and pulse shape could be more diverse. We could also make long pulses of up to 1~100[ms] in various pulse width. And the special differences between the existing system and the proposed system in this study are as follow. Existing system is one pulse(pulse width : 1~40ms) and proposed system is three pulse(pulse width : 1~100ms).
