Objectives : The purpose of this study was to analyze the propensity and find out the Syndrome Differentiation of teeth-mark tongue by taking survey and body examinations with 178 male patients. 164 patients out of 178 were checked up on Heart Rate Variability (HRV), Accelerated Photoplethysmograpy (APG), Body Composition. This study was also planned to find out the distinctive characteristics of teeth-mark tongue diagnosis and compare differences between Qi-Deficiency and Accumulation of Dampness and Phlegm patients group. Methods : The questionnaire was carried out targeting 178 male with teeth-mark tongue respondents among who had Oriental Health Examination and patients from the 3rd oriental-internal medicine department in Dongeui Hospital from $1^{st}$, March 2005 to $30^{th}$, April 2010. Only 164 patients were checked on HRV, APG and Body composition examinations. Results : It showed that 86 patients had Qi-Deficiency and 78 had Dampness and Phlegm but 14 couldn't be categorized. The major symptoms of Qi-Deficiency compared to Dampness and Phlegm were 'Frequent running nose', 'Soft stool', 'Chronic fatigue', and 'Eyestrain'. On the contrary, Dampness and Phlegm's dominant symptoms were 'Chest discomfort', 'Feeling bloated', 'Back pain', 'Feeling sluggish', and 'Itchy skin'. However, all symptoms were not matched with the Syndrome Differentiation of Qi-Deficiency or Dampness and Phlegm. It also showed that teeth-mark tongue patients' frequent symptoms were 'Stuffy nose', 'Feeling bloated', 'Oliguria', 'Shoulder pain', 'Chronic fatigue' 'Eyestrain' and these symptoms were matched with the Syndrome Differentiation of Qi-Deficiency and Dampness and Phlegm. In the results from this study, there were no significant differences between Qi-Deficiency and Dampness and Phlegm. Conclusions : It is hard to conclude that teeth-mark tongue could be only one to diagnose Qi-Deficiency or Dampness and Phlegm with 3 examinations.

Objective : To examine whether any correlation between tendency towards depression and tenderness at special acupuncture points exists, thus to explore the potential diagnostic property of acupuncture points. Methods : A total 31 subjects were included in this study. They filled out questionnaires about their mental [Beck Depression Inventory (BDI), Stress Response Inventory (SRI), Profile of Mood States (POMS)] and physical (fatigue due to overexertion, and food accumulation) symptoms. Identical weight around Alarm points (CV17, CV12, ST25, CV5, CV4, and LR13) and transport points (BL14, BL20, BL21, BL22, BL25, and BL27) was given using an algometer and the subjects rated their pain on an 11-point numerical rating scale. Heart rate variability (HRV) was also measured. Results : The subjects were divided into two groups, normal and depressive tendency groups with a cut-off point of nine on BDI. The depressive tendency group reported significantly higher values in SRI, POMS, and questionnaire for fatigue due to overexertion. In the pressure pain measurement, depressive tendency group had more pressure pain at CV12, left side of BL20, BL14, BL22 and both sides of BL21, BL25, BL27, significantly (each p<0.05). The data of HRV did not show significant differences between groups. Conclusions : People with a tendency towards depression may be prone to stress, negative mood, and fatigue due to overexertion. In addition, they may be more likely to develop tenderness at alarm points and transport points compared with healthy people. Further research is needed to confirm this finding.

This study is designed as a non-equivalent controlled before-and-after quasi-experimental study by having a control group for the effect of the interpersonal caring music activity program in children of single-parent families. Data collection was carried out in 22 children of single-parent families as the study group and in 23 children as the control group recruited from 22 community centers for children located in N city from July to September, 2014. As the study tool, the Heart Rate Variability (HRV) was used to measure loneliness, self-esteem scale and the stress response. With the collected data and using SPSS 18.0 for Window program, the Homogeneity test between the study group and the control group was conducted by using t-test and ${\chi}^2$-test while the study hypotheses were verified by analyzing with the independent t-test. The results of the study are as follows. Loneliness and self-esteem of the subjects did not show significant difference in the study groups. The sympathetic nervous system activity (normalized LF) has been lowered and the parasympathetic nervous system activity (normalized HF) has been increased as the stress response, while the sympathetic and the parasympathetic nervous system activity ratio (LF/ HF) score was lowered with significant difference, which had supported the hypotheses. Based on these results of this study, the interpersonal caring music activity program can be utilized as a stress management program for the children of single-parent families during a short period of time.

Objectives : The aim of this experiment was to investigate the influences of Autonomic Nervous System and EEG by conducting Reinforcement-Reduction(補瀉) acupuncture stimulation to compare the changes in acupoints on the body before and after treatment of acupuncture at Xingjian(LR2) being referred as Fire-point(火穴) and Ququan(LR8) being referred as Water-point(水穴) of Yin Liver Meridian(足厥陰肝經). Methods : This study was carried out on 30 healthy female volunteers in their 20's. There were four tests conducted throughout and the period for each test was between 2 to 5days. HRV and EEG were measured for 5 minutes before acupuncture stimulation was conducted on LR2-Reinforcement, LR2-Reduction, LR8-Reinforcement and LR8-Reduction at random. During the 20 minutes of acupuncture treatment, same subjects were measured simultaneously to observe any significant changes in acupoints. Again, the same subjects were measured for 5 minutes after removing the acupuncture in order to perform a comparative analysis. Results : The measurement of HRV showed that LF, LFnorm and LF/HF ratio increased significantly(p<0.05) while HF, HF norm decreased significantly in case of LR2-Reinforcement & LR8-Reduction. Both LR2-Reduction and LR8-Reinforcement induced a significant increase in HFnorm. EEG measurement indicated low $\alpha$ wave decreased and high $\beta$ wave increased significantly at LR2-Reinforcement during post-acupuncture period compared with acupuncture stimulation period. Both LR2-Reduction and LR8-Reinforcement developed significantly low $\alpha$ wave and high $\alpha$ wave. High $\beta$ wave increased significantly at LR8-Reduction during the acupuncture stimulation in comparison with pre-acupuncture period. Conclusions : The manipulation of acupuncture stimulation at LR2-Reinforcement and LR8-Reduction enhanced the activity of sympathetic nerves and the state of arousal while that of para sympathetic nerves declined. On the other hand, LR2-Reduction and LR8-Reinforcement developed the levels of para sympathetic nerves and relaxation.

Objective : SCP-20, a yeast hydrolysate from Saccharomyces cerevisiae, has exhibited anti-stress, anti-anxiety, and antidepressant effects in animal studies. The objective of this study was to test the effects of SCP-20 on healthy controls and to assess its effects on stress response, depression and, anxiety. Methods : Sixty-one healthy volunteers (30 male, 31 female) were recruited and screened for significant psychiatric and medical conditions. Baseline measures of stress, anxiety, and depression were taken using questionnaires such as the Stress Response Inventory (SRI), Beck's Anxiety Inventory (BAI), Beck's Depression Inventory (BDI), and the physiological measure of heart rate variability (HRV). Each subject was assigned randomly to a group taking capsules containing either 70% SCP-20 (i.e. the SCP70 group), 99.5% SCP-20 (i.e. the SCP99.5 group), or a placebo. Follow up measures were taken at week 4. Results : Subjects taking SCP-20 showed significant improvement in SRI and BAI scores compared to those taking placebo. For BDI scores, there was no significant difference between groups. No significant adverse effects were reported. Conclusions : This study suggests that SCP-20 is effective in alleviating stress and anxiety symptoms in healthy individuals, and has little or no side effects. However, the role of of SCP-20 in alleviating depression needs further clarification. Studiess examining its effects in psychiatric populations are needed to establish its role in alternative medicine.

In an experimental study, we assessed human sensibility in terms of psychophysiological response according to change of speeds (40, 70, 100km/h) in a driving simulator and application of motion fitters (washout filter, non-washout later) in a roller coaster simulator. For the driving and roller coaster simulators, a group of 12 healthy men in their twenties and a group of 8 healthy men in their twenties, respectively, participated. Participants each completed a simulator sickness questionnaire (SSQ), a subjective assessment of sensations of pleasantness, tension, and arousal, and perception of speed. Physiological signals were measured by 1/f fluctuation of EEG (electroencephalogram), ECG (electrocardiogram), and GSR (galvanic skin response). These were measured pre-to-post under the experimental conditions for each simulator. Subjective pleasantness, tension, arousal, and perception of speed and physiological responses indicating a feeling of pleasantness by 1/f fluctuation were higher for the roller coaster simulator than those measured for low speed driving in the driving simulator. The mean frequency of alpha band (8-l3㎐) in EEG increased with exposure to the driving simulator relative to that for the roller coaster simulator. Heart rate variability and GSR were significantly changed between pre- and post- under each condition in the driving and roller coaster simulators. The data suggest that subjective sensibility was elevated according to gain of speed and variety of simulator motion, and physiological responses were activated with increased speed.

The purpose of this study was to analyze the effect of acute respiratory training feedback upon a change on HRV-Autonomic nervous system in middle-aged women. The research subjects were totally 24 middle-aged women(40-60 years old), were randomly allocated 12 people to the respiratory training group and 12 people to the control group, and then were carried out the acute respiratory training. The feedback exercise in the respiratory training group was conducted for totally 15 minutes. Following the 10-minute breath awareness training according to the expert's guidance, the 5-minute autonomous breathing exercise was implemented. The data analysis was carried out Repeated Measures ANOVA with SPSS WIN 20.0. The conclusions that were obtained through this are as follows. The middle-aged women got significantly higher in SDNN, RMSSD, LF, HF after the acute respiratory training. Compared to the control group. the respiratory training group was indicated to have gotten higher significantly in SDNN, RMSSD, LF, HF. Mean HR and LF/HF were not shown a significant difference in both the main effect of group & period and the interaction effect of group & period. Above of a result the acute respiratory training feedback is effective for SDNN, RMSSD, sympathetic activity, parasympathetic activity in the middle-aged women. Thereby, the respiratory training program improves autonomic nervous system, being considered to be possibly expected the effective value of exercise intervention available for relieving stress and recovering autonomic dysfunction in the middle-aged women.

Dypepsia is the most common gastrointestinal disease and mainly occurs by stress or food. According to the cause of dyspepsia, the clinical characteristics and the curative process are different in patients. The purpose of this study is to compare acute dyspepsia patients depending on food factor and stress factor. For this study, we analyzed the cause, and the symptoms of 59 acute dyspepsia patients and divided them into two groups: one group is 27 acute dyspepsia patient group caused by stress factor (stress factor group). The other group is 32 acute dyspepsia patient group caused by food factor (food factor group). In addition, we carried out HRV test and compared HRV index between two groups. There was no significant difference in past illness involved in gastrointestinal tract diseases between two groups. There were big differences in the frequency of chest discomfort, thurst, lack of appetite, and exhaustion after meals between two groups. There were many changes of tongue fur in food factor group. But there were many changes of tongue body in stress factor group. The pulse pattern is mostly wiry in stress factor group. But, The pulse pattern is mostly slippery in food factor group. HF, TP were significantly lower than food factor group in stress factor group, it means autonomic nerve system was more suppressd in stress factor group than food factor group. Food factor group improved sooner than stress factor group. This study presented the clinically different characteristics (past medical history, symptoms, tongue diagnosis, pulse pattern, curative process) of acute dyspepsia depending on food factor and stress factor. Thus, it provides the necessity of oriental medical diagnosis and treatment called pattern identification for acute dyspepsia.

This study was conducted to examine the effect of tree density of Pinus koraiensis forest on the thermal comfort and the physiological response of human body in summer season. As the indicators of thermal comfort were used the predicted mean vote (PMV) and predicted percentage of dissatisfied (PPD), while the heart rate variability was used for the physiological indicator of subjects. The subjects were 15 physically healthy men and women in their 20s ($23.7{\pm}1.7$ years old). The subjects sat in each site to measure HRV for 5 minutes and the thermal comfort of each site was measured. As a results, it was proven by PMV and PPD that the Pinus koraiensis forest with 120% tree density was thermally more comfortable than the Pinus koraiensis forest with 80% tree density. In case of the subjects' physiological response, the Pinus koraiensis forest with 120% tree density showed significantly higher HF of HRV than the Pinus koraiensis forest with 80% tree density and significantly lower LF/HF. Therefore, the findings of this study scientifically proved that the Pinus koraiensis forest with 120% tree density is thermally more comfortable and physiologically more relaxing than the Pinus koraiensis forest with 80% tree density.
