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.

Effects of Korean red ginseng (KG) and western ginseng (WG) on body temperature, pulse rate, clinical symptoms and hematological changes in human were studied after administration p.o. with Korean red ginseng and western ginseng for 10-days. KG was more effective in keeping homeostsis in than western ginseng in the changes of body temperature and pulse rate. KG was more effective in low body temperature and SOEVMIN (소음인), while inducing tachycardia especially in SOYANGIN (소양인) and TAEEUMIN (태음인). WG tended to drop temperature abruptly and also descended pulse rate with greater range than KG. KG and WG could cause side effects such as headache and gastrointestinal syndromes and induce hypertension or hypotension abruptly in specific constitutions. However, KG and WG did not cause abnormal changes in urinalysis and hematology.

In this experimental study we Proposed the double dielectric barrier discharge (DDBD) reactor to produce as high an electric field as possible. The experiment are conducted for applied voltage from 15 to 20[tV], flow gas rage at 2[1/min] and pulse rate at 120[pulses/s] and 240[pulses/s]. SPD connection of DDBD which combine the surface discharge with the silence discharge was most effective to reduce the NOx. In the decomposition efficiency per watt, the low pulse rate gave hotter efficiency than that of the high pulse rate. However in DeNOx rate, the high pulse rate gave better performance than that of the low pulse rate. NOx removal rate increased with increasing the applied voltage in all reactors.

In this experimental study we proposed the double dielectric barrier discharge (DDBD) reactor to produce as high an electric field as possible. The experiment are conducted for applied voltage from 15 to 20[kV], $1~4[\ell/min]$ of gas flow rate and 120[Hz] and 240[Hz] of pulse rate. Superposition discharge(SPD) generated in DDBD which combined the surface discharge with the silence discharge was the most effective to reduce the $NO_x$. In the decomposition efficiency per watt, the low pulse rate gave better efficiency than the high pulse rate. However in DeNOx rate, the high pulse rate gave better performance than the low pulse rate. $NO_x$ removal rate and efficiency increased with increasing the applied voltage in all reactors.

The vascular reaction such as the indirect blood pressure and the pulse rate of the tail to the noise were examined in 8 naive Sprague-Dawley rats of both sexes. The sounds used in the experiment were 1KHz and 4 KHz, 95dB pure tone generated by Nagashima Audiometry. The indirect blood pressure and the pulse rate were checked at the rat tail by Polygraph at 5 minutes interval. The results were as follows: 1. The blood pressure and the pulse rate increased maximally 5 minutes after the exposure to both sounds. 2. The blood pressure and the pulse rate returned normal range within 20 minutes after the exposure of both sounds. 3. The increment of the blood pressure and the pulse rate was greater after the sound of 4KHz than after that of 1KHz, but it wasn't statistically significant.

Objective : Auricular acupuncture is a method of treatment that involves needling the ear in order to produce relief of symptoms. This concept was first developed by P.Nogier, french doctor and referred to as somatotopic representation. Many authors have commented the fact that the vagus nerve supplies the external auditory and the concha. The aim of this randomised, single blind study was to investigate whether auricular acupuncture of the ear produced changes in the pulse rate, an indicator of vagal tone. Methods: 10 healthy man volunteers were divided into normal and epinephrine stimulation group. Then each group was divided into vagus area acupuncture and control area acupuncture group again. Epinephrine stimulation group was injected by epinephrine 0.3cc twice, first. All of them were needled in either the vagus area or control area of the ear, and pulse rate changes were measured by patient monitor over 1 hour. Results : In the epinephrine stimulation group, there was significant differences in the pulse rate change between vagus area acupuncture and control area acupuncture group. After injection of epinephrine, the basal pulse rate was increased 1.3~1.4 times in the control group. However, in the vagus area acupuncture group the basal pulse rate was increased only 1.1~1.2 times.

Observation of changing pattern of blood pressure and pulse rate of enflurane anesthesia for 200 cases operations, performed during the past 4 years(1983~1986) in Yeungnam University Hospital have been evaluated clinically. In order to observe the influence of enflurane upon the blood pressure and pulse rate during general anesthesia, the authors prepared a formula, expressing changing of blood pressure and pulse rate by time series and analyzed the types and distribution pattern in the experiment. The results obtained were as follows : 1. Blood pressure and pulse rate were increased at the time of intubation. 2. Generally, blood pressure and pulse rate were increased at the time of intubation and then stabilized withing 20 minutes. 3. Most common patterns were identified, ADEE type was 73~74%, Which is most common type and AEEE type was about 40%.

The purpose of this study was to test the effect of guided imagery on blood pressure and pulse rate. The subjects were thirty-nine nursing students in I university located in Busan, Korea To enhance the effect of treatment, they were trained getting themselves absorbed in guided imagery on three different occasions before the study. Actually in the study, the subjects were given instruction in Mason's guided imagery for 19 minutes and 58 seconds. Blood pressure and pulse rate were measured before and after guided imagery application. The data were analyzed through paired t-test. The Results were as follows : 1) There was a significant decrease in systolic blood pressure after the use of guided imagery. 2) There was no significant decrease in diastolic blood pressure after the use of guided imagery. 3) There was a significant decrease in pulse rate after the use of guided imagery. These results indicate that guided imagery is a helpful technique for decreasing blood pressure and pulse rate, which are increased in stress condition.

Pulse rate is known to be related to diverse phenotypes, such as cardiovascular diseases, lifespan, arrhythmia, hypertension, lipids, diabetes, and menopause. We have reported two genomewide significant genetic loci responsible for the variation in pulse rate as a part of the Korea Association Resource (KARE) project, the genomewide association study (GWAS) that was conducted with 352,228 single nucleoride polymorphisms typed in 8,842 subjects in the Korean population. GJA1 was implied as a functionally causal gene for pulse rate from the KARE study, but lacked evidence of replication. To re-evaluate the association of a locus near GJA1 with pulse rate, we looked up this signal in another GWAS conducted in a Health Examinee-shared cohort of 3,703 samples. Not only we were able to confirm two pulse rate loci (1q32.2a near CD46 and 6q22.13c near LOCL644502) identified in the KARE GWAS, we also replicated a locus (6q22.31c) near GJA1 by the lookup in the Health Examinee GWAS. Considering that the GJA1-encoded protein is a major component of cardiac gap junctions, a functional study might be necessary to validate its genuine molecular biological role in the synchronized contraction of the heart.

Objectives: The purpose of this study is to investigate the relationship between bone age, chronological age, anthropometric parameters, and diagnosed pulse rate on child-adolescence's growth according to sex and the revelation of secondary sexual characteristics. Methods: Growth-concerned 44 children and adolescence (from 6 to 16 years) were analyzed in retrospective study. They visited Korean Medical Clinic in Suwon, Korea from January 2012 to October 2013. Individual bone age (BA), chronological age (CA), Risser sign, anthropometric parameters, and pulse rate were measured. The correlations of each variable were done by Pearson analysis, Spearman analysis and Regression analysis. Results: 1. The female group was shown to have stronger negative correlation between pulse rate and BA, CA than the male group. In gender analysis, the female group showed negative correlation between weight and pulse rate. 2. In a further analysis according to the revelation of secondary sexual characteristics, the group of child-adolescent without secondary sexual characteristics was shown to have stronger negative correlation between pulse rate and BA, CA than the group with secondary sexual characteristics. The height percentile and pulse rate were negative correlation in secondary sexual character being. 3. The Risser sign and pulse rate were not correlated in this study. Conclusions: These findings suggested that a regular and continual measurement of pulse rate is effective in estimating potential for growth in child-adolescent group.
