In this paper, the power spectral analysis of heart rate variability(HRV) was performed to evaluate effects of orthostatic stress with head-up tiIt on autonomic nervous system(ANS) for 25 healthy male subjects(age : 24 $\pm$ 5 yr.) and a new method was proposed to assess the autonomic balance. The ECG and respiration signals were recorded at tiIt angles of $0^{\circ}$, $45^{\circ}$, $90^{\circ}$and $0^{\circ}$ successively for 10 minutes per each stage under the condition of frequency controlled respiration(0.25Hz). Heat rate(HR) gradually increased ils the angle increased Similarly, according to the increment of angle, normalized low frequency component(0.05-0.15Hz) gradually increased, whereas normalized high frequency component (0.20-0.30Hz) was reduce4 From these results it is speculated that orthostatic stress head-up tiLt, results in the prevalence of sympathetic tone in autonomic balance with the increment of sympathetic tone and the decrement of parasympathetic tone, which seems to meanthat autonomic nervous system plays a major role in compensating for disturbances of cardiovascular system due to it.

In this paper, the power spectral analysis of heart rate variability(HRV) was performed to evaluate effects of orthostatic stress with head-up tilt on autonomic nervous system(ANS) for 20 healthy male subjects(age : 245 yr.) and a new method was proposed to assess the autonomic balance. The ECG signals wore recorded for 3 minutes in both the supine and 70 head-up tilt positions, and then the HRV signals underwent power spectrum analysis at each position. The results of this study suggest that cardiac autonomic functions, such as sympathetic tone in autonomic balance with the increment of sympathetic tone and the decrement of parasympathetic tone which occur during head-up tilt position, arc not sufficient to overcome tile orthostatic stress arising in Cerebral Palsy.

This study aims at grasping the relativity between laborers' yangseng level and stress so as to present the groundwork for preventive oriental medicine approach in industrial health. The researcher prepared the questionnaire on general character, health-related yangseng level and chose 632 people to execute Autonomic balance test through heartbeat change. The collected material was analyzed by SPSS and tested by T-test, ANOVA. The general yangseng level average is 3.27, morality yangseng 3.91, sleep yangseng 3.39, mind yangseng 3.32, sex life yangseng 3.29, exercise yangseng 3.14, activities and rest yangseng 3.07, diet yangseng 2.95, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. In the aspect of yangseng level : Having a spouse, Non-smoking, Non-drinking, Regular exercising, Sufficient sleeping have higher yanseng levels. In Autonomic balance test, age from 35 to 40 has the highest autonomic activity and job period from 5 years to 10 years has the highest stress resistance. Non-smokers have high autonomic activity and stress resistance. Further, have low autonomic balance, stress index and fatigue strength. In the case of regular exercising person, he/she has high autonomic activity and stress resistance with low stress index. Regarding sleeping time, autonomic balance is the highest when he/she sleeps less than 6 hours. Stress resistance is the highest when he/she sleeps 7 hours and stress index is the highest when he/she sleeps 6 hours. After comparing the relativity between yangseng level autonomic balance test, only exercise yangseng has plus factor on autonomic activity and stress resistance and minus factor on stress ind ex and fatigue strength. Yangseng level has been affected by individual character and daily habits. Also stress is more influenced by daily habits than by individual character. We can find the relativity of exercise yangseng between yangseng and stress which suggests that we need to take measures to win over stress in individual health in the near future.

Objective: Disorder of the autonomic nervous system is considered to be the cause of primary dysmenorrhea. The spine has a close relationship with the autonomic nervous system, and the sacrum is mechanically and neurologically connected to the uterus through ligaments. Therefore, this study was conducted to check the effect on the autonomic nervous system through measurement of heart rate variability by applying manual therapy to the sacroiliac joints of subjects with primary dysmenorrhea and to suggest an effective treatment method for dysmenorrhea. Design: Randomized controlled trial. Methods: Thirty females with dysmenorrhea were assigned to either the manual therapy group and sham treatment group according to the random treatment method. The manual therapy was applied to the sacroiliac joints, and the sham treatment was only treated with the hands placed in the same position of the intervention. Heart rate variability and the Visual Analogue Scale (VAS) were measured on the day when menstruation began ±2. Interventions were performed between the groups, followed by a 5-minute break and then re-measurements were made. Results: There were significant differences in autonomic balance and VAS scores in the manual therapy group before and after the intervention between groups (p<0.05). In the sham treatment group, there were significant differences in low frequency, autonomic balance, and VAS scores (p<0.05). There were significant differences in autonomic balance between groups (p<0.05). Conclusions: In females with primary dysmenorrhea, manual therapy applied to the sacroiliac joint was found to be effective for a short time on autonomic activity.

Purpose: This study reviewed the pathophysiological mechanisms of cellular aging caused by psychological stress and aimed to establish a biobehavioral theoretical framework for nursing interventions to promote autonomic balance based on these mechanisms. Methods: A comprehensive literature review was conducted. Results: A review of the literature showed that the stress response increases the secretion of catecholamines and glucocorticoids, resulting in a greater allostatic load. This load induces inflammatory reactions and oxidative stress, shortening telomere length and damaging mitochondrial DNA, which can lead to cellular aging. Based on this mechanism, a biobehavioral theoretical framework for nursing interventions was established. This framework focuses on delaying or inhibiting the cellular aging process by acting on the stress response stage and improving autonomic balance. Conclusion: According to the proposed biobehavioral theoretical framework, stress-relieving nursing interventions may act on the mechanism of cellular aging caused by stress responses. We believe that this framework could expand our understanding of the biobehavioral aspects of stress and would facilitate efforts to use biomarkers to evaluate the effectiveness of stress-related nursing interventions at the cellular level.

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.

Objectives : The purpose of this study was to investigate differences between traffic accident and non-traffic accident patients in the early stage, by analysis of the heart rate variability(HRV) and visual analogue scale(VAS). Methods : This study carried out on 38 patients who complained of nuchal or lower back pain. They have received hospital treatment in Dae-Jeon Univ. Cheonan Oriental Hospital. In the TA(Traffic accident) group, the pain caused by TA and in non-TA group, the pain caused by other reasons. We measured HRV and VAS twice(pre-treatment(Tx.) and post-Tx.). Then we analyzed the data. Results : As time goes by, patients who complained of pain showed the inclination to improve ability to balance autonomic nerve system. And fatigue and pain were improved. But they showed the inclination to increase stress index. At pre-Tx., TA group had more stress and worse ability to balance autonomic nerve system, but showed lower fatigue index than non-TA group. But, as time goes by, in TA group the fatigue and autonomic balance got worse. At pre-Tx., non-TA group complained of more severe pain than TA group, but at post-Tx., TA group complained of more severe pain than non-TA group. In other words, in TA group, the decreasing rate of pain was lower than non-TA group. Conclusions : Results from this investigation showed that TA have a negative effect on stress index, ability to balance autonomic nerve system, fatigue index and decreasing rate of pain. These results are expected to consider characteristics of patients who complained of pain caused by TA.
