Exposure to stress can lead to sympathetic hyperactivity, which include a systemic disease with lesions in a broad spectrum of organs and a psychiatric condition. The purpose aimed to evaluate the effect of the korea ginger essential oil on stress hormone and brain tissue response in chronic mild stress-induced rats model of sympathetic hyperactivity. Evaluation method carried out cytotoxicity assessment and component analysis, what observe the effects based on serum biomarker and histopathological analysis of brain tissue. As this time, the korea ginger essential oil was treatment at doses of 100 nl/㎖ for 2 weeks after make a chronic mild stress-induced rats model of sympathetic hyperactivity. As a result, the korea ginger essential oil was not toxic at less than 100 nl/㎖, contents of 6-gingerol was 345 ppm. Compared to the control rats, the korea ginger essential oil treatments significantly reduced the serum concentrations of stress hormone (i.e., ACTH, corticosterone, melatonin). Furthermore, The korea ginger essential oil treatments effectively preserved the TH-immune response was occasionally interrupted in the ventral tegmental area (VTA) and the substantia nigra pars compacta (SNpc). The results indicate that the korea ginger essential oil improved sympathetic hyperactivity. Thus, the korea ginger may be a novel material of aroma oils for the management of sympathetic hyperactivity.

Objectives: Chronic pain is one of the most common experiences of humans and a typical psychophysiological disorder. The aim of this study was to measure the psychophysiological responses in chronic pain patients using a biofeedback system, and to compare them with the results from normal healthy subjects. Methods: Forty two patients with chronic pain (17 males and 25 females, average age $44.67{\pm}11.10$ years) and 42 normal healthy controls (17 males and 25 females, average age $45.17{\pm}10.46$ years) participated in this study. Electromyography (EMG), skin conductance (SC), and skin temperature (ST) were recorded using biofeedback system during the 3 phases (baseline, stress, and recovery) of stress reactivity test, and average values of them were calculated. Difference of values between two groups in each corresponding phase was analyzed with independent t-test, and change of values across phases of stress reactivity test was analyzed with paired t-test (all two-tailed, p<0.05). Results: Compared to normal controls, chronic pain patients had higher value of EMG (baseline: $8.10{\pm}5.97{\mu}V$ vs $4.72{\pm}1.52{\mu}V$, t=-3.56, p<0.01; stress: $11.25{\pm}6.89{\mu}V$ vs $8.49{\pm}4.78{\mu}V$, t=-2.13, p<0.05; recovery: $7.12{\pm}3.77{\mu}V$ vs $4.78{\pm}1.59{\mu}V$, t=-3.70, p<0.01) and SC (baseline: $1.06{\pm}1.0{\mu}S$ vs $0.42{\pm}0.29{\mu}S$, t=-4.0. p<0.01; stress: $1.87{\pm}2.05{\mu}S$ vs $1.03{\pm}0.86{\mu}S$, t=-2.47, p<0.05; recovery: $1.74{\pm}1.77{\mu}S$ vs $0.64{\pm}0.59{\mu}S$, t=-3.8, p<0.01) in all the 3 phases. But, skin temperature comparison did not reveal significant differences in all the 3 phases between two groups. Conclusion: Psychophysiological responses of chronic pain patients in stress reactivity test were different from those of normal healthy controls. These results suggest that sympathetic nervous system is more activated in chronic pain patients.

피로(疲勞)의 사전적 의미는 과로로 인해 정신이나 몸이 지쳐 힘든 상태를 말한다. 과도한 업무나 스트레스, 수면부족, 지나친 음주 등으로 인해 신체 리듬이 깨지면 피곤함을 쉽게 느끼게 된다. 대부분 충분한 휴식을 취하면 피곤함이 덜어지는데 휴식을 취해도 1개월 이상 피로가 계속되면 지속성(prolonged)피로, 6개월 이상 지속되면 만성(chronic)피로를 분류된다.

본 논문에서는 섬유형 전극을 부착한 Chest Belt형 소형 저전력 단일 채널 ECG 시스템을 통한 심박 신호를 무선 전송하고 개인용 휴대 이동통신 단말기가 이를 수신하여 HRV(Heart rate variability)를 분석하고 이를 이용하여 정신적 스트레스 상태를 판단할 수 있는 스트레스 지수를 도출할 수 있는 시스템을 설계하고자 한다. 이를 위하여 저전력 MCU 설계를 통한 HR 모듈 및 검출 알고리즘을 개발하고 감정 상태를 분석할 수 있는 알고리즘을 제안한다. 본 연구의 결과는 일반인이나 만성절환자의 스트레스 상태를 감지하여 스트레스를 낮춰주는 음악 및 호흡 등을 통해 사용자의 스트레스를 감소 등의 건강관리에 활용될 수 있을 것으로 사료된다.

This study developed a program that integrated MBSR-K and progressive muscular relaxation for the health and well-being of patients with chronic pain, and proved its effectiveness by studying 40 chronic pain patients. This program used nature of mind, body scanning meditation, breath meditation, mindfulness meditation, Hatha yoga and progressive muscular relaxation to ease chronic pain. Whenever negative feelings and emotions such as fear, anxiety, and pain occurred, the program focused on those emotions and observed the outcome. This program, which was based on the results of the preceding studies, was composed of eight courses. Major findings of the study are as follows: First, the meditation group that was composed of patients with chronic pain had significant decrease of physical symptoms compared to the control group. Second, to confirm the outstanding features of the participating patients with chronic pain that brought change in the effect of the program, characteristics of clients were analysed. Third, the program factor that influenced the effectiveness of the treatment process was evident when the training was performed twice a week rather than having once a week of training and second week for homework.
