  • Objectives: The information on the depth where pulse wave appears is as important as pulse waveform. The aim of this study was to classify pulse pattern using pressure-height(P-H) volume-curve by 5 applied pressure levels to find out the information on the depth of pulse and interpret the floating & sinking pulse in oriental medical pulse diagnosis. Methods: We used 3 dimensional pulse imaging analyser (DMP-3000, DAEYOMEDI Co., Korea), which measures radial pulse waveforms noninvasively by way of tonometric method at 5 applied pressure levels, and shows P-H volume-curves by applied pressure. 448 subjects were enrolled, pulse waveforms were measured and the P-H volume-curves were gained on the three locations of Chon, Kwan, and Cheok. Results: Gained P-H volume curves were classified into 3 types ; increase type, decrease type, and increase-decrease type. Increase-decrease type appeared more often on Chon and Kwan, while increase type appeared more often on Cheok. In a few cases, decrease-type appeared on Chon and Kawn, however it never appeared on Cheok. Conclusions: Through the classification of pulse by P-H volume-curve, we gained the information on the depth of pulse. We speculate the decrease type as floating pulse, the increase-decrease type as middle pulse, and the increase type as sinking pulse in oriental medical pulse diagnosis. After more researches on P-H volume-curve by applied pressure, the P-H volume-curve may be used as an important factor for pulse diagnosis.

  • Objectives: Pulse energy values recorded with an add-pres sure-type pulse apparatus were correlated with Sasang constitutional syndromes in order to match pulse energy values with Sasang prescriptions. Methods: The pulse energy values were measured with Daeyo Pulse Apparatus at the Gwan pulse point of both wrists. Prescriptions were divided into two major categories of interior syndromes or exterior syndromes, and categorized according to major component herbs specific to each of the four Sasang constitutions, and the relationship between the pulse energy and each groups divided by their prescription was studied. Results: About 10% of all people had nonmal pulse energy values. 10% had values over normal range, and $70\sim80%$ had lower values than normal. The normal range of pulse energy was regarded as being between 450 and 700. Conclusions: 1. For patients of the Soeum constitution, prescriptions without Panax ginseng is suitable for patients with high pulse energy, and prescriptions containing Panax ginseng are suitable for patients who have lower pulse energy. 2. All prescriptions for the Soyang constitution containing Rehmannia radix preparata or Comus officinalis are suitable for patients who have lower pulse energy, and prescriptions containing Rehmannia radix or Gypsum fibrosum are applicable to patients with pulse energy values higher than normal. 3. Most prescriptions for the Taeum constitution containing Semen coicis or Semen castaneae are suitable for patients with lower pulse energy, and prescriptions containing Radix puerariae or Radix et rhizoma rhei can be prescribed for patients who have lower pulse energy levels. 4. The Taeyang constitutional prescription Ogapijangcuck-tang is suitable for patients who have higher pulse energy levels and Mihudeungsikjang-tang is better for patients with lower than normal pulse values. As described above, the pulse energy level of each patient can be matched with a specific Sasang constitutional prescription. If this relationship is taken into consideration with other conventional symptoms, it can be helpful in diagnosis, improving efficacy of treatment, and be used as objective evidence.

  • Pulse diagnosis is considered one of the most important diagnostic methods in traditional Korean medicine. Nonetheless, there have been troubles of using pulse diagnosis practically, for the lack of its differential standards and standardized terminology. Rapid pulse belongs to the several traditional pulse types. Rapid pulse was first mentioned in the chinese medical book Haungdineijin that matched it to the fever as well as yang in the human body. Meanwhile, chinese doctors in Ming Ching dynasty of China suggested that rapid pulse meant more of the yin, cold-related reaction than yang and fever. In this study, we organized the past arguments of the rapid pulse and went back tracking what biological activities could be possibly linked to the rapid pulse. Thus, we figured out that the inflammatory mechanism has a close connection with the rapid pulse. The definition of the rapid pulse in Haungdineijin was indicating the acute inflammatory response, while in Ming Ching dynasty, it indicated the chronic inflammation. This is the deficiency-excess pattern of the rapid pulse. Furthermore, we discussed the nonexpression pattern of the rapid pulse which could be happened in case of the heat stroke, etc.

  • A high voltage pulse generator based on the Blumlein pulse forming line (PFL) was fabricated to produce a voltage pulse whose peak value is ~300 kV and pulse duration is ~50 ns. Three cylindrical electrodes, such as inner, middle, and outer electrodes, are concentrically placed to make a compact PFL. To increase the pulse duration of the output pulse without any change of the size of the generator, the middle electrode is replaced by a helical strip electrode. To determine the radius of the helical electrode, the impedance of the helical Blumlein PFL is calculated using an approximate formula where the dispersive property of the helical Blumlein PFL is not considered. The dependence of the impedance on the frequency is computed by a commercial program. The number of turns in the helical electrode is decided to provide a demanded pulse duration. The experimental result shows that the helical Blumlein PFL is capable of making a high voltage pulse of ~50 ns pulse duration.

  • The acupuncture procedures in Hwangjenaekyung (黃帝內經) was different to modern ones in many aspects. Especially, the role of pulse diagnosis in acupuncture was totally different and the pulse diagnosis was essential part in acupuncture therapy in Hwangjenaekyung era. We found four noteworthy features on the pulse diagnosis before and after acupuncture in Hwangjenaekyung : (1) Pulse diagnosis was a mandatory process in acupuncture (2) Doctors who used pulse diagnosis in 12 meridians (十二經脈遍診脈法), pulse diagnosis in 9 points of 3 body parts (三部九候脈法), and comparative pulse diagnosis between radial artery and carotid artery (人迎寸口對比脈法) followed the former rule ((1)). (3) The major pulse features to detect before and after acupuncture were conversion between the vacuous pulse (虛脈) and the replete pulse (實脈), and conversion between slippery pulse (滑脈) and rough pulse (澁脈). (4) Deukki (得氣, Deqi) was synonym of Kiji (氣至), and it referred to the changes of arterial pulse, not the sensation followed by acupuncture manipulation.

  • A compact size high voltage pulse generator with nanosecond rise time has been designed and investigated experimentally. The inductance of a pulse generator can be reduced by fixing the Marx generator and pulse forming network components into a single cylindrical unit. As a result, nanosecond rise time about $8{\sim}10[ns]$ and pulse width of several hundred [ns] can be obtained from a modified Marx pulse generator. And parametric studies showed that the rise time of the output pulse was depended little on the change of the load resistance and the charging capacitance while, the pulse width of the output pulse was depended greatly upon the change of the load resistance and the charging capacitance. The theoretical showed the possibility to design the laboratory-size pulse generator very fast rising time and a proper pulse width by minimizing stray inductance and varying resistance and capacitance.

  • The aim of this study is to examine the reliability of Inyoung-Chongu pulse diagnosis by analyzing Inyoung-Chongu pulse measured on normal people. I measure the size of Inyoung & Chongu pulse, ratio of Inyoung to Chongu, and ratio of Chongu to Inyoung on 50 normal people. Inyoung pulse of normal people is $6.44{\pm}1.62$ volt and Chongu pulse of normal people is $6.81{\pm}1.70$ volt. The ratio of Inyoun to Chongu is $1.03{\pm}0.50$ and that of Chongu to Inyoung is $1.12{\pm}0.41$. Through this experiment, I conclude that the Inyoung-Chongu pulse diagnosis is reproducible on normal people and can develop pulse diagnosis device through comparison between Inyoung and Chongu pulse.
