Pulse is one of the basic diagnostic information of TKM(Traditional Korean Medicine). To quantify and standardize pulse diagnosis, we had collected an amount of clinical data from May 2005 by using newly developed pulse analyzer. But there were many noises in pulse wave according to measuring method, environment, operator and condition of patient. So some data can’t be included for analyzing diagnosis. To reduce noises from measuring pulse and to collect reliable pulse wave data, we made the process map of measuring method and applied six sigma project. With this we can improved the method of measuring pulse wave in collecting clinical data. The project follows a disciplined process of five macro phases: define, measure, analyze, improve and control (DMAIC). A process map and C-E diagram are used to identify process input and output variables. The major input variables are selected by using C&E matrix, and process map is developed by analyzing input variables. And the optimum process conditions are going to be controled to avoid in increasing loss of collecting pulse wave data.

Objectives : The purpose of this study was to analyze the characteristics of the pulse energy in women who complained mild hyperemesis gravidarum. Methods : We analyzed the values of pulse energy on 14 patients who suffered mild hyperemesis gravidarum. The patients’ symptoms were assessed by PUQE (Pregnancy-Unique Quantification of Emesis scale). Statistical analysis was performed using SPSS 18.0 for window program, one way ANOVA, pearson correlation coefficient. Results : The results were as follows. 1. There were no statistically significant pulse energy differences. 2. The Chon pulse energy showed negative correlations with each Kwan and Cheok. 3. PUQE score showed positive correlations with right Chon pulse energy and negative correlations with right Kwan pulse energy. Conclusions : The result suggested that PUQE score changes be positive related with spleen pulse energy and negative related with lung pulse energy.

This paper describes the design and fabrication of a partial discharge(PD) analyzer to evaluate insulation performance for low-voltage electrical and electronic devices. The analyzer consists of an adjustable AC power supply, a coupling network, an amplifier, a shielding encloser, a sample-hold (S/H) circuit and a data acquisition (DAQ) board. The analyzer holds the height of PD pulse for $10{\mu}s$ by the S/H circuit, and this makes possible to measure PD pulses having fast rise and short duration by a low speed analog-to-digital (A/D) converter. The data are transmitted to the personal computer through the DAQ board, and the designed analysis program calculate apparent charges, discharge inception and extinction voltages.

Objectives: This study was aimed to develop a guideline for the application of diagnostic devices for menopausal syndrome. Methods: We conducted a literature review and a questionnaire survey on diagnostic devices including Digital Infrared Thermal Imaging (DITI), pulse diagnosis device, Heart Rate Variability (HRV), body composition analyzer, Yangdorak. Results: We retrieved some clinical values for usage of devices from the articles. Especially, DITI was useful to identify the pattern of body temperature distribution. The respondents answered that they diagnosed menopausal syndrome by using body composition analyzer (62.3%), DITI (60%), HRV (60%), pulse diagnosis device (45.7%), Yangdorak (34.3%). The respondents answered that they don't use diagnostic devices when they diagnosed menopausal syndrome because of absence of device, cost, difficulty of interpretation, substitution of another diagnostic method. After experts survey, it was recommended to use DITI, HRV, body composition analyzer. There was no consensus on the use of pulse diagnosis device, Yangdorak in diagnosing menopausal syndrome. Conclusions: We developed a guideline for the application of diagnostic devices for menopausal syndrome.

The resonant frequency modulation of $YBa_2Cu_3O_{7-x}$ meander lines has been investigated as functions of optical pulse energy and temperature by using a network analyzer. The frequency-domain measurements are performed by controlling both the resonant frequency and the frequency width. The meander lines, configured in a microstrip geometry, are illuminated by optical pulses from an actively mode-locked Nd:YAG laser. The variation of the resonant frequency shows a quadratic dependence on the reduced optical pulse energy $P/P_c$, where $P_c$ is defined as the critical optical pulse energy at which resonance signal has disappeared. As for the dependence on temperature, the results are in good agreement with the previously reported data.

Pulse feeling is one of the most important diagnosis method in Oriental medicine. But it is not easy to make an objective and standardized diagnosis. In this study, we found how to quantify diagnosis. Specially dally the high practicality in clinic, we search some parameters especially well-related to floating and sinking pulse by statistic analysis. By extension, we find the pulse patterns of the floating and sinking pulse. We choose 15 subjects diagnosed as floating pulse and 15 subjects diagnosed as sinking pulse by oriental doctors. And their pulse signals were acquired by Pulse analyzer which has piezoresistive pressure sensor. For the quantification of the floating and sinking pulse, at first, we examined the parameters which were highly correlated with oriental doctor's diagnosis. And then we derived pulse patterns of the floating-sinking pulse from preprocessed signal and its ensemble average. We also looked trend variation (PH-Curve) between contact and pulse pressure. As a result, statistically there is the biggest difference between contact pressure, the maximum pulse pressure, diastolic area (Ad) and floating and sinking data. Through the PH-Curve, which represented the relationship between contact and pulse pressure, we could divide the floating and sinking pulse clearly. As a basic research of pulse diagnosis algorithm, we can contribute to select essential parameters in diagnosis algorithm And using these diagnosis method, we expect to find typical pulse patterns and some useful parameters about other pulses like slow/rapid, large/fine pulse and so on. We hope that this study will contribute pulse objectification.
