Since ${\ll}$Hwangjenaegyeong(黃帝內經)${\gg}$ and ${\ll}$Nangyeong(難經)${\gg}$, there has been various methods in pulse diagnosis. The Chon-gu(寸口)/Inyeong(人迎) Pulse Comparison Diagnosis which is dealt with in many chapters of the ${\ll}$Hwangjenaegyeong${\gg}$, has not been as widely applied as the Chon-gu Pulse Diagnosis due to several limitations. In this paper, we will review these limitations and suggest an alternative method. In the Chon-gu/Inyeong Pulse Comparison Diagnosis, we compare the Chon-gu Pulse and the Inyeong Pulse to see which is larger than the other by times, and diagnose illness of the 12 Meridian Pulse. It is fairly clear which is larger than the other, but to determine by how much accurately is quite difficult to say. However if we combine the Five Viscera Pulse in application, it becomes far more easier to determine which viscera and bowel is ill. First, study the pulse of the Chon-gu and In-yeong, then determine the Viscera Pulse. Next, determine the larger pulse between the Chon-gu and In-yeong pulse.

Objectives : This paper is to find the meaning of Tan pulse in Qikooujiudamai Diagnosis, Methods : In terms of Qikooujiudamai, the position to diagnose the Intermittent Pulse is Kwan(關) position and the pulse is Tan(彈) pulse. To find the meaning of Tan pulse, the symptoms of Intermittent pulse were analyzed. Then the symptoms were analyzed in terms of both Qikooujiudamai Diagnosis and 28-pulse diagnosis to find the correlation. Results & Conclusions : The Tan pulse at Kwan position is related to Hyen(弦), Kin(緊), Hwal(滑), Dan(短) pulse in 28-pulse diagnosis. The symptom of disease of Intermittent pulse's diagnosis is mostly concluded to those 4 pulses. Qikooujiudamai is the diagnosis for acupucture treatment, but with 28-pulse diagnosis, it can be developed to usage of medicine.

We describe the pulse forming of pulsed $CO_2$laser using multi-pulse superposition technique. A various pulse length, high duty cycle pulse forming network(PFN) is constructed by time sequence. That is, this study shows a technology that makes it possible to make various pulse shapes by turning on SCRs of three PFN modules consecutively at a desirable delay time with the aid of PIC one-chip microprocessor. The power supply for this experiment consists of three PFN modules. Each PFN module uses a capacitor, a pulse forming inductor, a SCR, a High voltage pulse transformer, and a bridge rectifier on each transformer secondary. The PFN modules operate at low voltage and drive the primary of HV pulse transformer. The secondary of the transformer has a full-wave rectifier, which passes the pulse energy to the load in a continuous sequence. We investigated laser pulse shape and duration as various trigger time intervals of SCRs among three PFN modules. As a result, we can obtain laser beam with various pulse shapes and durations from about 250 $mutextrm{s}$ to 600 $mutextrm{s}$.

Objectives: For the traditional pulse diagnosis in Oriental Medicine, not only the pulse shape in time domain, but the width, length and depth of arterial pulse also should be measured. However, conventional pulse diagnostic systems have failed to measure the spatial parameters of the arterial pulse e.g. effective length of arterial pulse in the wrist. In fact, there are many ways to measure that kind of spatial features in arterial pulsation, but among them, the method using image sensor provides relatively cheap and simple way, therefore I tested feasibility of measuring 2-dimensional pressure distribution by imaging devices. Methods: Using widely used PC cameras and dotted balloons, the subtle oscillation of skin over the radial artery was recorded continuously, and then the displacement of every dot was calculated. Consequently, the time course of that displacements shows arterial pulse wave. Results: By the proposed method I could get pressure distribution map with 30Hz sampling rate, 21steps quantization resolution, and approximately 1mm spatial resolution. With reduced quantization resolution, $3cm{\times}4cm$ view angle could be achieved. Conclusion: Although this method has some limitations, it would be useful method for detecting 2-dimensional features of arterial pulse, and accordingly, this method provides a novel way to detect 'narrow pulse', 'wide pulse', 'long pulse', 'short pulse', and their derivatives.

Objective : In Donguibogam(東醫寶鑑), like a slow pulse with irregular intervals(結脈), an abrupt pulse(促脈) and a slow and weak pulse with regular intervals(代脈), an uneven pulse is written as a kind of arrhythmia. Such a recognition differs from the present one. In this study, I try to seize the meaning and deliberate whether those expressions are appropriate. Method : 1. Collect and compare the materials of the above four pulses among documentary records of feeling the pulse for diagnosis. 2. Grasp the aspect and trend of changes. 3. Reason whether records in Donguibogam(東醫寶鑑) are proper or not. Result & Conclusions : Donguibogam(東醫寶鑑) written "like a slow pulse with irregular intervals(結脈), an abrupt pulse(促脈) and a slow and weak pulse with regular intervals(代脈), an uneven pulse is written as a kind of arrhythmia". It is not 'an uneven pulse' is written about irregularity of pulse, but 'an uneven pulse' is written about irregularity of the sense able to be felt on the fingertip.

Transcranial magnetic stimulation utilizes the method of controlling applied time and changing pulse by output pulse through power density control for diagnosis purposes. Transcranial magnetic stimulation can also be used in cases where diagnosis and treatment are difficult since output pulse shape can be changed. As intensity, pulse range, and pulse shape of the stimulation pulse must be changed according to lesion, the existing sine wave-shaped stimulation treatment pulse poses limitations in achieving various treatments and diagnosis. This study actualized a new method of transcranial magnetic stimulation that applies a 3 Stage 2 Switch( power semiconductor 2EA) for controlling pulse repetition rate by achieving numerous switching control of stimulation coil. Intensity, pulse range, and pulse shape of output can be freely changed to transform various treatment pulses in order to overcome limitations in stimulation treatment presented by the previous sine wave pulse shape. The method of freely changing pulse range by using 3 Stage 2 Switch discharge method is proposed. Pulse shape, composed of various pulse ranges, was created by grafting PFN (Pulsed Forming Network) through AVR AT80S8535 one-chip microprocessor technology, and application in transcranial magnetic stimulation was achieved to study the output characteristics of stimulation treatment pulse according to delaying time of the trigger signal applied in section switch.

In this paper, we devised a pulse rate detection system to provide basic clinical index of cold-hot diagnosis of oriental medicine. The system consists of pulse signal detection, respiration signal detection, electrocardiograph detection, A/D conversion and computer system parts. We define a pulse rate by a pulse count to the respiration period inspiration pulse rate by a pulse count to the inspiration period, and expiration pulse rate by a pulse count to the expiration period. The clinical experiments for normal Person to evaluate the pulse rate detection system show the pulse/respiration ratio of 4.30${\pm}$1.03, the pulse/inspiration ratio of 1.60${\pm}$0.32, the pulse/expiration ratio of 2.37${\pm}$0.75.

The pulse diagnosis is an important method in Oriental Medicine. Recently, there have been continuous attempts to replace the finger palpation by Oriental medical doctors (OMDs) by more objective tools based on machines, e.g., pulse analyzers. To improve the performance of the pulse analyzers, both the machine-appropriate interpretations for the pulse images appeared in the literature and the improvement in the repeatability and reproducibility of the measurement sensors are to be developed. As an attempt towards the transformation of the pulse images in terms of machine-appropriate language, in this work, we suggest an upgraded algorithm for the solid/deficient pulses, which are the two representative pulse images informing us how strong the pulse pressure is. It has been argued that one could determine the solid/deficient pulses by the maximum pulse pressure from pulse analyzers. However, by a clinical test, we found that the maximum pulse pressure alone is not sufficient to determine the solid/deficient pulses. In addition to the maximum pulse pressure, the mean pulse pressure averaged over for five different hold-down pressures(3-D MAC) is needed to improve the agreement with the OMD's decision for the solid/deficient pulse. We found that, among the data diagnosed with having either the solid pulse or deficient pulse by OMDs, the novel algorithm showed 86.0% diagnosis rate and 81.6% concordance rate.
