Objectives: In this study, the meditation programs (${\alpha}$ version), which are properly coordinated according to the motion, breathing, and relaxation, are evaluated and researched upon to have positive effects on stress and in the area of psychology. Methods: Approved by the Clinical Trials Deliberation Committee in Oriental Medicine, Dongguk University, Ilsan Hospital, this study collected data according to the applicant's consents, demographic information and anthropometry for the Sasang Constitutional diagnosis. Sasang Constitutional diagnosis measured the beta tools by Institute of Oriental Medicine and a decision tree was made for the Sasang Constitutional questionnaires. The STAI, STAXI, BDI, and HRV were measured before and after the meditation in order to compare the effects of meditation according to Sasang Constitution. The HRV was used as a ProComP KM Tech (co). Results: 1) The positive changes available in the Time-domain analysis of heart rate variability assessment showed that the peace of mind is increased. By analyzing the Sasang constitution, So-eum In's peace of mind included a physical stability of the autonomic nervous system. 2) According to the psychological scale evaluation, each depression scale, trait anger, anger-in, state anxiety and trait anxiety index proved significantly positive effects. By analyzing the Sasang constitution, Eun-In which involved So-eum In and Tae-eum In, had positive effects. 3) The psychological scale changed the group of diagnosed depression or anxiety, it did not mean that the psychological scale changes in the depression group, but the index of the anxiety group had been significantly reduced. This program had clinical effects for anxious patients and Eum-In which involved Tae-eum In and So-eum In according to the analysis of Sasang constitution. 4) Correlations between the gender of each psychological scale showed that women have overall low correlations, but, there were no significant changes. Conclusions: The meditation program developed by adequately mixing Action, relaxation and breathing shows that it is effective for overall Eum-in physical and mental relaxation and concentration. In the future, It will have to be developed Meditation program to show the same effect for all people.

Objectives : To assess the characteristics of electropyography(EMG) and heart rate variability(HRV) values in idiopathic facial palsy inpatients of different Sasang constitutions. Methods : Medical records of 103 idiopathic facial palsy inpatients who underwent facial EMG testing and HRV testing were retrospectively reviewed. All subjects had been consulted to the department of Sasang constitution for constitution differentiation. The Sasang constitutional and age distribution were initially analyzed, and axonal loss percentage values on EMG were correlated with Sasang constitution and sex. HRV results were also correlated with Sasang constitution and sex. Results : 1. 24.4 percent of idiopathic facial palsy inpatients were of the Soyang constitution, 52.4 percent were of the Taeum, and 23.3 percent were of the Soeum. Patients in their fifties were most common in all constitutions(27.8%). 2. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in the Taeum constitution compared with Soyang or Soeum(p<0.05). 3. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in men than women(p<0.05). 4. The mean LF/HF ratio was significantly lower in idiopathic facial palsy inpatients of the Soeum constitution compared with Soyang and Taeum(p<0.05), but there was no statistically significant difference in mean MHRT, SDNN, TP, VLF, LF, and HF of different constitutions. 5. The mean SDNN was significantly lower in women inpatients compared with men(p<0.05), but there was no statistically significant difference in mean MHRT, TP, VLF, LF, HF, and LF/HF ratio. Conclusions : The Sasang constitutional composition of idiopathic facial palsy inpatients closely adheres to the composition proposed in Dong-eui-su-se-bo-won, but the Taeum and Soeum proportion is slightly larger and the Soyang proportion slightly smaller. Axonal loss value on EMG was significantly lower in the Taeum constitution, and in men(p<0.05, <0.05). Mean LF/HF ratio was significantly lower in the Soeum constitution compared with Soyang and Taeum(p<0.05), and mean SDNN was significantly lower in women(p<0.05).

Objectives: Cold Hypersensitivity of Hands and Feet (CHHF) has been diagnosed objectively by Digital Infrared Thermal Imaging (DITI) and has been known to be associated with autonomic nervous system (ANS), which can be assessed by Heart Rate Variability (HRV). This study evaluated the correlation between severity of CHHF and HRV variables.Methods: We studied 155 non-menopausal women with CHHF who visited Kyung Hee University Hospital at Gangdong from 01 October 2013 to 30 April 2016. We measured DITI and HRV of each patient. We used DITI to calculate the severity of CHHF with thermal difference between upper arm (L4, 俠白穴) and palm (P8, 勞宮穴) of both hands and anterior thigh (ST32, 伏兎穴) and dorsum of foot (LI3, 太衝穴) of both feet. The correlation between severity of CHHF and HRV variables were analyzed.Results: In time domain analysis, there was significantly positive correlation between the severity of CHHF and both SDNN and RMSSD. In frequency domain analysis, there was significantly positive correlation between the severity of CHHF and TP, HF and HF Norm while there was significantly negative correlation between the severity of CHHF and LF Norm as well as between the severity of cold hypersensitivity of both hands and LF/HF ratio.Conclusions: The more severe CHHF is, the more increased the function of parasympathetic nerve system (PNS) and relatively decreased the function of sympathetic nerve system (SNS) is. Also, it has known that cold hypersensitivity could be caused by deficiency syndrome and qi deficiency has the same ANS tendency as CHHF. Therefore, in practical fields, this result can be helpful in planning treatment and deciding prognosis in respect of deficiency syndrome.

Objectives : This study was accomplished to investigate the effects of moxibustion at Jeonjung($CV_{17}$) on the heart rate variability(HRV) in healthy adults. And based on that, we tried to find out how moxibustion at Jeonjung($CV_{17}$) effects on the activity and balance of the autonomic nervous system Methods : We investigated on 50 healthy volunteers consisted of 24 subjects in moxibustion group and 24 subjects in control group. On the other hand, two volunteers were ruled out by standard of elimination. The study was established by randomized trial. Moxibustion was applied at Jeonjung($CV_{17}$) and rested during 10 minutes in moxibustion group. No treatment was executed in control group. We measured HRV 3 times : baseline measurement and after treatment in moxibustion group(after rest in control group) twice. The SPSS 12.0 for windows was used to analyze the data by paired t-test, Wilcoxon signed ranks test(in group) and Independent t-test, Mann-Whitney U-test (between the groups). Results : 1. In moxibustion group, mean HRT decreased significantly. Ln(VLF) increased significantly. Ln(TP) decreased significantly at $2^{nd}$ time and increased significantly at $3^{rd}$ time. SDNN, RMSSD, PSI, Ln(LF), Ln(HF), Normalized LF, Normalized HF and LF/HF ratio were not affected. 2. In control group, PSI and normalized HF decreased significantly. SDNN, Ln(TP), Ln(VLF), normalized LF and LF/HF ratio increased significantly. Mean HRT, RMSSD, Ln(LF) and Ln(HF) were not affected. Conclusions : This study suggest that moxibustion at Jeonjung($CV_{17}$) makes no effects on the balance of the autonomic nervous system.

Background : Recently a discussion about Qi including a study about the effect or the theory of acupuncture is getting prevailing in various angles. In most of studies about acupuncture stimulus, 'Filiform acupuncture'(毫鍼) is used. A study about Nine kinds of acupuncture(九鍼), except 'Filiform acupuncture'(毫鍼) has not been reported yet, and there is no study about using a special acupuncture made for controling Qi either. Objectives : 'DONG CHU CHIM' can be used for patients who are scared of a pain because it is a medical Qikong tool and non-invasive stimulus one. To assess a effect of Qikong operation using 'DONG CHU CHIM' objectively, we stimulated non-invasive to Sobu point of 30 normal adults using 'DONG CHU CHIM' and examined the result in the basis of high confirmed and repetitive HRV which is a functional assessment method of the autonomic nervous system. Method : This study has been proceeded in three periods. Total was 35min : 10min for the former and latter period of acupuncture stimulus, l5min for the acupuncture stimulus period. For each period, we measured 5min of 3 times(Stage I, II, III). Result : Comparing the changes of HRV during pre-stimulation and post-stimulation, HRT was significantly reduced, LOGTP, LOGVLF, LOGLF, LF/HF were significantly increased and SDNN, LOGHF were generally increased but did not show any significant changes. So we think that the stimulus of 'DONG CHU CHIM' affects on the sympathetic system and parasympathetic system, it activates the autonomic nervous system, and it makes the inequality of the sympathetic and parasympathetic nerve to be equal status. Conclusions : We can conclude that the non-invasive stimulus of 'DONG CHU CHIM' can affect significantly to the autonomic nervous system. So it can be used in clinic as a tool of Qikong operation, and it can be also used to weak patients or children because it doesn't give a lot of pain like 'Filiform acupuncture'(毫鍼) compared to invasive stimulus. By the basis of this study, more studies about the effect of 'DONG CHE CHIM' should be done in the future.

Objective : The effects of electroacupuncture(EA) stimulation on heart rate variability(HRV) for healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The HRVs of every 10 minute for 22 healthy volunteers(13 men and 9 women) were measured for an hour with SA-3000P(Medicore Co., Ltd., Korea). The median age with arithmetic range of 13 men and 9 women was 26.00 years with 22.75~27.00 years. The initial 20 minutes were defined as baseline period(pre-EA period), the following 20 minutes as the EA period and the last 20 minutes as the post-EA period. In each EA periods, volunteers received EA(2Hz, 0.6~0.8ms duration, maximal tolerated stimulation without discomfort) on the right Zusanli(ST36), Shangjuxu(ST37) acupoints while supine, resting. Results : Heart rate of volunteers at post-EA period was significantly decreased compare to that of pre-EA period, while SDNN at post-EA period was significantly increased. Heart rate at EA period was significantly decreased compare to that of pre-EA period, but Ln(LF) and LF/HF at EA period were significantly increased. Ln(HF) at post-EA period was significantly decreased compare to that of EA period, while the other variables were not significantly changed. Conclusions : The results suggest that EA in healthy adults is associated with changed activity in the sympathetic and parasympathetic nervous system. Further study is needed for investigating the effects of EA on HRV and autonomic nervous system.

Objectives A normal circadian rhythm of autonomic nervous system function stands for the daily change of sympathetic and parasympathetic modulation, which can be measured by heart rate variability (HRV). Generally, patients in the intensive care unit (ICU) are prone to sleep-wake cycle dysregulation, therefore, it may have an influence on the circadian rhythm of autonomic nervous system. This study was designed to interpret possible dysregulation of autonomic nervous system in ICU patients by using HRV. Methods HRV was assessed every 3 hours in 21 ICU patients during a 7-minute period. The statistical differences of HRV features between the morning (AM 6 : 00-PM 12 : 00), and the afternoon (PM 12 : 00-PM 18 : 00) periods were evaluated in time domain and frequency domain. Results Patients showed significantly increased normalized power of low frequencey (nLF), absolute power of low frequencey (LF)/absolute power of high frequencey (HF) in the afternoon period as compared to the morning period. However, normalized power of high frequency (nHF) was significantly decreased in the afternoon period. There was no statistically significant difference between the morning period and the afternoon period in the time domain analysis. Conclusions The increased sympathetic tone in the afternoon period supports possible dysregulation in the circadian rhythm of autonomic nervous system in ICU patients. Future studies can help to interpret the association between autonomic dysregulation and negative outcomes of ICU patients.

본 연구에서는 경호경비현장에서 이루어지고 있는 실제적인 경호경비원들의 장시간 경계근무 중 발생하는 하는 생체리듬의 변화를 알아보기 위해 K대학교 경호학과 학생 9명을 대상으로 실제 경계근무와 같은 형태로 180분간 경계근무를 실시하였다. 30분 간격으로 HRV(Heart rate variability)를 통하여 심박동 변이도와 자율신경검사를 실시 한 결과 심박동 변이도 HRT과 SDNN은 유의한 차이가 없어 180분간의 경계근무 시간 동안 안정적으로 유지 하였다. 자율신경계의 전체적인 활성정도를 반영하는 TP는 안정시 보다 90분과 120분에 유의(p<.05)한 차이로 높게 나타났다. 또한 120분 이후에는 유의한 감소하여, 120분 이상의 경계근무에서는 자율신경계의 활성도가 감소하는 것으로 나타났다. VLF, LF, HF 모두 유의한 차이는 아니지만 120분에 감소하는 경향을 보여 TP 변화에 영향을 주었다. 교감신경과 부교감신경의 균형도를 나타내는 LF/HF ratio는 경계근무 30분에 유의하게(p<.05)높은 것으로 나타났다. 따라서 경계근무 120분 이후에는 집중력이 감소하는 것으로 사료되며, 경계근무 시작 30분 까지는 근무시작으로 인한 긴장감과 흥분감이 있는 것으로 나타났다.

Objective : The effects of Indium-Gallium-Aluminium-Phosphide(InGaAlP) laser transcutaneous irradiation on heart rate variability(HRV) in healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The control group consisted of 20 healthy volunteers (10 men, 10 women). The experiment was divided into 5 different periods, the pre-1st laser period(10 minutes), the 1st laser period(30 minutes), the post-1st laser period(5 minutes), the 2nd laser period( 30 minutes) and the post-2nd laser period(30 minutes). HRV was measured for 5 minutes at the pre-1 st laser period, the post-l st laser period and the post-2nd laser period. The laser period is the period in which InGaAlP laser transcutaneous Irradiation treatment occurs. Results : 1. SDNN of volunteers at post-1st laser period and post-2nd laser period significantly increased compared with that of the pre- 1 st laser period. 2, Ln(VLF) at post-I st laser period significantly increased compared with that of pre-1st laser period, while Ln(HF) at post-2nd laser period significantly decreased compared with those of pre- I st laser period and post-1st laser period, 3. Ln(TP) at post-1st laser period and post-2nd laser period significantly increased compared with that of pre-1st laser period, 4, LF/HF Ratio at post-2nd laser period significantly increased compared with those of pre-1st laser period and post-1st laser period. But the other variables did not significantly change. Conclusions : The results suggest that InGaAlp laser transcutaneous Irradiation in healthy adults is associated with the autonomic nervous systems. Further study is needed for investigating the effects of laser irradiation on autonomic nervous systems.
