This study was designed to research whether Dinamika can yield a suitable diagnosis for Activity of Autonomic Nene System on stroke. The testing of Dinamika was carried out at Oriental Medical Centar of Dong-Eui University with the participation of 27 patients. The results of Dinamika examinations shows as follows : Group A(the rising of a parasympathetic nerve system) is 0 persons. And Group B(the balancing autonomic none system) is 4 persons. Group C(the rising of a sympathetic nerve system) is 23 persons. There are 7 persons that it is difference of more than $20\%$ between B1 (the control ability of autonomic nerve system) and B2(the potential energy to control autonomic nerve system), 11 person that B1 and B2 are less than $10\%$, 1 person that B1 and B2 are balanced about $60\%$, 8 person that it is balanced domain from $10\%\;to\; 60\%$ between B1 and B2. According to this study on activity of autonomic nerve system using Dinamika on Stroke, these results suggest that 27 patients evidence the problem of autonomic none systems.

A model of the cardiovascular system coupling cell, hemodynamics and autonomic nervecontrol function is proposed for analyzing heart mechanics. We developed a comprehensive cardiovascular model with multi-physics and multi-scale characteristics that simulates the physiological events from membrane excitation of a cardiac cell to contraction of the human heart and systemic blood circulation and ultimately to autonomic nerve control. Using this model, we delineatedthe cellular mechanism of heart contractility mediated by nerve control function. To verify the integrated method, we simulated a 10% hemorrhage, which involves cardiac cell mechanics, circulatory hemodynamics, and nerve control function. The computed and experimental results were compared. Using this methodology, the state of cardiac contractility, influenced by diverse properties such as the afterload and nerve control systems, is easily assessed in an integrated manner.

We have studied the effect and application of CST which is the function and disease of the autonomic nerve system based on recovery of flexibleness of the autonomic nerve. CST purpose to keep sustenance of human body by recovering joints have limitation of mobility and controlling autonomic nerve system by diminution tense of the sympathetic nerve. CST makes well flowing of CSF by pressure the fourth ventricle of the brain or relaxation of soft tissues of the base of a cranial bone. There is no result of studies about CST in Korea yet. It will bring a benefit if it prove the effect of CST in countries depend on drugs way high such as Korea. It needs positive approach and definite research for the improvement.

Purpose: The purpose of this study is to determine effects of aromatherapy on the activity and balance of autonomic nervous system and on physical resistance to stress. Methods: This research is a primitive experimental design which attempts to analyze aromatherapy EKG monitoring on real-time basis. Lavender & Chamomile, each 30 drops, were blended with 100ml Sweet Almond oil. Subjects was laid relaxed, and had insides of his wrists and ankles attached with electrodes for EKG. Right after applied with essential oil onto his philtrum and parotid, started on EKG monitoring. Results: The activities of parasympathetic and sympathetic nerve were changed as time elapsed, with significant differences(p=.000). In multiple comparison, the value was significantly different(p<.05).The balance of autonomic nerve was changed, becoming close to the normal level in accord with applicable international standards(1.5)(p=.011). In multiple comparison, the value showed a significant difference(p<.05). Physical resistance to stress increased with the passage of time, but not statistically significant. Conclusions: This suggests that aromatherapy can be used as a nursing intervention which aims at alleviating symptoms related to the imbalance of autonomic nerve system such as headache, hot flashes, irregular heartbeat, nervousness, depression and anxiety.

Purpose: The purpose of this study was to investigate the therapeutic effect of non-invasive vagus nerve stimulation by transcutaneous electrical nerve stimulation application on the autonomic nervous system of human body. Methods: Participants were seventeen healthy adults. Standard deviation of all normal N-N intervals(SDNN), root mean square of successive differences(RMSSD), low frequency(LF), high frequency(HF) were compared in pre and post Mean values after intervention. Data were analyzed in Wilcoxon's signed-ranks test. Results: The results of this study is that sistolic blood pressure and pulse rate decreased mean value after non-invasive vagus nerve stimulation by transcutaneous electrical nerve stimulation. High frequency, low frequency, SDNN, RMSSD increased mean value in heart rate variability after intervention. But that is not significant except for SDNN. Conclusion: Non-invasive vagus stimulation by transcutaneous electrical nerve stimulation effect on parasympathetic nerve stimulation, and then it might be effective method for autonomic nerve balance control.

Objectives This study investigated the relationship between exercise and health factors including vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system etc. Methods The subjects were 20,509 persons who had received health examination by Korean Medicine and submitted questionnaires about exercise history, for 8 months from March to November in 2011. The vaso-aging degree were measured by APG (Accelerated Photoplethysmograph). The stress index and resistance, fatigue and activity of autonomic nerve system were measured by HRV (Heart Rate Variability). We analyzed the relationship between exercise and various variables by chi-square test with SPSS ver. 19.0. Results Regarding the relationship between exercise and vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system, there were significant differences(p<0.05). Conculsions This study suggests that vaso-aging degree, stress index, stress resistance, fatigue and activity of autonomic nerve system are affected by exercise.

Transcutaneous auricular vagus nerve stimulation (taVNS) is known to be effective in improving symptoms of numerous diseases such as depression and epilepsy by increasing vagus nerve activity through electrical stimulation. The purpose of this study is to investigate the effect of vagus nerve stimulation on the activity of autonomic nervous system and the changes in postprandial blood glucose levels. Seven healthy adults participated in a non-invasive transcutaneous auricular vagus nerve stimulation experiment. taVNS (25 Hz, 200 ㎲, biphasic pulse) was applied to the cymba concha (taVNS group) or the earlobe (Sham-taVNS group) of the left ear. As autonomic nervous system signals, skin conductance level, skin temperature, and heart rate were recorded during the application of taVNS. Postprandial blood glucose changes due to food intake were recorded at 5 min intervals for 25 minutes after taVNS or sham-taVNS. The taVNS showed a significantly lower skin conductance level than the shamtaVNS (p < 0.05). The increase rate of postprandial blood glucose was significantly lower in the taVNS than in the sham-taVNS (p < 0.05). These results showed that taVNS reduced the activity of the sympathetic nerve system and alleviated early rise in postprandial blood glucose. Although further studies in diabetic patients are needed, this study suggest that taVNS has a potential for clinical use to improve postprandial blood glucose.

This study compared the heart rate variability tests of healthy college students and chronic fatigue patients for 2 years. Study subjects were idiopathic chronic fatigue patients who carried out the HRV tests and students conducted HRV test when health screening test. Study subjects were 250 people, 104 people and men (41.6%), women were 146 patients (58.4%). In patient group, the autonomic nervous system activity was decreased, the activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced compared to the control group(Patient:84.17±16.27, Control:98.33±17.28). Regardless of gender, patient group's autonomic nervous system activity was decreased, the activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced, compared to the control group(Patient Female:84.17±16.27, Patient Male:84.07±14.96/Control Female:98.33±17.28, Control Male:96.45±16.92). Even though same ages, patient group's autonomic nervous activity was reduced compared to control group(Patient:89.36±12.43, Control:97.39±16.91). Fatigue patients' activity of the sympathetic nerve and the parasympathetic nerve were significantly reduced, regardless of the fact that activity of the sympathetic nerve is increased and the parasympathetic nerve is decreased in stress state like an impassioned injury(七情傷). Therefore HRV test is useful to diagnose Fatigue from this study.

Objective: Stress is one of the most important etiological factors in our lives. Human body makes effort to keep his homeostasis from stress by using autonomic nerve system. So we need markers which can evaluate autonomic nerve system easily. HRV represents such markers. Sympathetic and Parasympathetic nerve system are part of autonomic nerve system, related with cur body and diseases in ENT, Dermatology, Ophthalmology are also deeply related with stress, Sympathetic and Parasympathetic nerve system. So we can expect that it can help understanding patients to evaluate autonomic nerve system with HRV Research Methods and Procedures: Forty one patients who have seif-recognized stress in Dept. of Oph & Otolaryngo & Dermatology were selected. SDNN. RMSSD, LF, HF, norm-LF, norm-HF, LF/HF ratio, LnLF, LnHF were checked. Results: Men showed lower SDNN, HF, and LnHF than women(p<0.05). Age over-forty group showed significant lower SDNN, LF, HF, LnLF, LnH(p<0.01), and lower RMSSD(p<0.05) than age under-forty group. There's no big differences for age at norm-LF, norm-HF, and LF/HF ratio. Skin disease group showed higher SDNN, RMSSD, LF, HF, LnLF, LNHF than the others, facial palsy group showed higher norm-HF. LF/HF ratio, and mouth-throat group showed higher norm-LF, but there's no statically significant difference. Comparing skin disease group with the others, the others showed statically significant low SDNN(P<0.01), RMSSD, LF, HF, LnLF and LnHF(P<0.05).
