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.

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.

We report a passive Q-switching of an all-fiber erbium-doped fiber laser delivering high pulse energy by using a high quality single-walled carbon nanotube saturable absorber (SWCNT-SA). A side-polished fiber coated with the SWCNT is employed as an in-line SA for evanescent wave interaction between the incident light and the SWCNT. This lateral interaction scheme enables a stable Q-switched fiber laser that generates high pulse energy. The central wavelength of the Q-switched pulse laser was measured as 1560 nm. A repetition rate frequency of the Q-switched laser is controlled from 78 kHz to 190 kHz by adjusting the applied pump power from 124 mW to 790 mW. The variation of pulse energy from 51 nJ to 270 nJ is also observed as increasing the pump power. The pulse energy of 270 nJ achieved at maximum pump power is 3 times larger than those reported in Q-switched all-fiber lasers using a SWCNT-SA. The tunable behaviors in pulse duration, pulse repetition rate, and pulse energy as a function of pump power are reported, and are well matched with theoretical expectation.

Purpose: The purpose of this study is to analyze the characteristics of the pulse energy in women who complain of climacteric and menopausal symptoms. Methods: We analyzed the values of pulse energy on 45 climacteric and menopausal women. The patients' symptoms were assessed by Kupperman's index and Menopause Rating Scale (MRS). Statistical analysis was performed using SPSS 18.0 for window program, one way ANOVA, pearson correlation coefficient. Results: The results were as follows. 1. The pulse energy of the Left Chon was significantly largest and Left Cheok was comparatively smallest. 2. There was no statistically significant correlation in the pulse energy of Left Chon minus Left Cheok, Kupperman's index, MRS total sum score. Conclusions: The results suggest that the pulse energy of the Left Chon tends to be increased and Left Cheok decreased in climacteric and menopausal women.

To reduce the laser pulse shape distortion accompanying the amplification process and achieve an intended output pulse shape in the Nd:YAG amplifier chain, we propose a frequency-modulated pulse-amplification method. Assuming carrier-frequency-modulated seed pulses, we numerically simulate the pulse amplification in an Nd:YAG amplifier chain where severe distortion occurs. For the calculation, we develop a modified Frantz-Nodvik equation, which enables two inputs with different carrier frequencies. The simulation results indicate that the temporal contrast of the seed pulse needed to obtain a flat output pulse shape is reduced by 16 - 25 dB when frequency modulation is applied.

Purpose: This study was performed to find correlations between Edema Index and Pulse Energy in early postpartum period. Methods: Fiftynine postpartum women were participated in this study which was conducted with Inbody 720 (Biospace Co. Ltd) and 3D Blood Pressure Pulse Analyzer (3D-MAC). Edema Index (Extra Cellular Water/Total Body Water) calculated after body composition analysis and 3D-MAC result (Pulse Energy) were analysed within a week after delivery. Results: The results were as follows 1. Edema Indexes of the upper, lower limbs, trunk and whole body were associated with each other respectively. 2. Edema Indexes and Right Kwan pulse energy had significant positive correlation. 3. Right Kwan pulse energy showed positive correlations with Left Kwan, Right Chon, Right Cheok. Conclusions: Viscera associated with Postpartum Edema are Spleen, Lung, Liver and Vital Gate. The most important thing is thought to be Spleen.

Near-fault ground motions can impose particularly high seismic demands on structures due to the pulses that are typically observed in the velocity time-histories. In this study it is empirically found that the critical response can be estimated from the directions corresponding to the maximum (max) or minimum (min) pulse-energy. Determination of the pulse-energy requires removing of the high-frequency content. For achieving this, the wavelet analysis and the least-square-fitting (LSF) algorithm are adopted. Results obtained by the two strategies are compared and differences between them are analyzed. Finally, the relationship between the critical response and the response derived from directions having the max or min pulse-energy confirms that using the pulse-energy for deriving the critical response of the building structures is reasonable.
