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.

Background : Sasang Constitutional Medicine (SCM) is the field of traditional Korean medicine that emphasize four constitutional types for diagnosis and treatment. Appearance, personalities and pathological characteristics are main factors of Sasang constitutional classification. Previous studies carried out by the pulse analyzer showed that the pulse wave can discriminate these types. In addition, It was reported that the pulse wave are affected by age and sexuality. In this study, we investigated the pulse wave characteristics related Sasang constitution types in control group regarding their age and sexuality. Subjects and Method : Two hudred and eighteen volunteers participated in this study: healthy men in $20{\sim}49$ years old. Participants were interviewed and examined to evaluate their health condition and Sasang constitution type. Then they were tested with pulse analyzer when they ere stabilized. The pulse at the radial artery just beside styloid process was measured, because this area is landmark for pulse diagnosis in oriental medicine. 3-D Mac pulse analyzer (Daeyo Medi Co. Ansan. Korea) was used in this study. We analyzed main features of pulse waves with the Sasang condtitution types by the SPSS for Windows (ver 12.0). Results : There was significant difference between Taeum and other types in contact pressure as weil as in coefficient of floating and sinking pulse. Conclusion : By analyzing pulse waves of healthy adult men. we found significant differences exist between Taeum and other types. These pulse differences may characterize Taeum type, and it will be helpful for the evaluation of Taeum type.

Objectives: Many types of dust collector are used for industrial ventilation, with the most common types being the cylinder bag filter system, rectangular bag filter system and cylinder type cartridge filter system. The cylinder type cartridge bag filter, which has more filtering area than other types of bag filter, can increase the pulse time and extend the useful life of the filter. This can save operational costs and installation area. Materials: This study used cylinder type cartridge bag filter equipment and tested the impact of vibration level and filter pressure with different pulse jet cleaning conditions. The final, cleaning efficiency was calculated through input dust mass and cleaning dust mass Conclusions: Two optimum cleaning condition groups were found. The first condition group was $3kgf/cm^2$ pulse pressure, 15 cm pulse distance, 0.2 s pulse time with an H-10 type nozzle. The second condition group was $3kgf/cm^2$ pulse pressure, 15 cm pulse distance, 0.3 s pulse time with an H-10 type nozzle.

Objective : The purpose of this study is to demonstrate the characteristics of pulse diagnosis in infertile women. Methods : We have studied 38 women infertility patients in the Dunsan oriental hospital by using pulse diagnostic device. Pulsation and pulse types have been analyzed with variables of infertility factors. Statistical analysis was performed by adopting descriptive and inferential tests. Results : Both right and left chi parts were shown different from other parts. In small intestine and gall bladder showed significantly different pulsation according to the infertility factor. Short pulse, fine pulse, skipping pulse, shallow pulse and deep pulse were often representative pulse types for the main organs of woman infertility. In Triple energizers showed significantly different shallow pulse type according to the infertility factor. Conclusion : The results corresponded closely with previous literature on pulse diagnosis about infertile women.

The study of the Rana plancyi, was done during the calling period at a pond in Osong, Chungbuk, Korea from May to the middle of August of 1996 and 1997. Five basic types of call-A, B, C, D, E, - were identified in Rana plancyi according to the structure of call types. The structure of A type call has only one pulse, B type call has two pulses and C, D type call has one separated pulse which is called introductory call and pulse group as follow it. On the other hand, E type call has 3-6 separate pulses. The interval between introductory call and pulse group is $0.73{\pm}0.29$ s(n=159) in C type call and $0.60{\pm}0.21$ s (n=48) in D type call. The number of pulses in the pulse group is $30.08{\pm}8.69$ in C type call and $15.78{\pm}2.40$ in D type call. An increase in water temperature induces a decrease in C and D type call duration (C type call r= -0.4153, p<0.001, D type call r=-0.7064, p<0.001). In case of C and D type call, the interval between introductory call and pulse group influenced more call duration than pulse group duration. We regarded A, B type call as a territorial call and C, D type call as a mating call and we recognized that E type call has the function of threat or alarm.

This experiment was performed to confirm the hypothesis that LLLT had biostimulation effect for all kinds of cells and there would be differences in the growth of cells among different types of pulsed laser. 360 samples were used in this study. The samples were randomly divided in 6 groups according to the pulse type : quasi continuous type (CW), pulse 1(P1), pulse 7(P7), pulse 9(P9), pulse 15(P15) and shame-irradiated control(Co) groups. Energy fluences of all experimental groups, P1, P7, P9, P15 and CW were 2.12, 2.12, 6.37, 57.32 and 31.85 mj/cm2 respectively. All samples were irradiated for every 1 minute at 0, 12, 24, 36, 48 and 60 hours. Ten samples of each group were sacrificed at 0 and every 12 hours and then the optical density of all samples was measured with the spectrophotometer. As a result, some types of pulses showed significant differences among groups. The increase of cells were markedly stimulated with laser irradiation in P7 and P9 groups, while inhibited in CW, P1, and P15 groups compared with control group. It is therefore, suggested that specific laser pulse should be recommanded to have the biostimulation effects on the specific tissue or cells, although the biostimulation effect is does dependant.
