  • 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.

  • Objectives : The purpose of this study was to examine the effects of auricular acupuncture at the Shinmun on patients with dementia by using power spectrum analysis. Electroencephalogram(EEG) power spectrum show site-specific and state-related differences in various frequency bands. Methods : Study was carried out in 38 subjects.(31 patients with dementia and 7 normal people, 27 females and 11 males ; mean age=75.9 years old). To know the effect of auricular acupuncture at the Shinmun in patients with dementia, we measured electroencephalogram(EEG) of normal people and patients with dementia about 'before', 'after' and 'after 15 minutes' giving auricular acupuncture at the Shinmun, and compared the brain wave($\alpha$, $\beta$, $\delta$, $\theta$) of EEG 30 channels. Results : In the case of patients with dementia, in the power values of $\alpha$(alpha) band at F4, FP2, FCZ, F8, FC4 channels (p<0.05) during the Shinmun-auricular acupuncture treatment increased significantly. In $\beta$(beta) band, the power values at T8 channel(p<0.05) during the Shinmun-auricular acupuncture treatment increased significantly. In $\delta$(delta) band, the power values at F7, FP1, FZ, FP2, FCZ, C4, FC4, CP4, T8, P7, P3, O1, OZ, O2, P4, P8 channels(p<0.05) during the Shinmun-auricular acupuncture treatment decreased significantly. In $\Theta$(theta) band, the power values at O1, OZ, O2channel(p<0.05) during the Shinmun-auricular acupuncture treatment decreased significantly. Conclusions : Through these results, we concluded that auricular acupuncture at the Shinmun on patients with dementia could have effect the functional mechanism of the cerebral cortex.

  • 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 Gold Chim(DCG-chim, 東樞金鍼)' can be used for patients who are scared of a pain because it is a medical Qi-gong tool and non-invasive stimulus one. To assess a effect of Qi-gong operation using DCG-chim objectively Methods : The present study was performed to elucidate the effects of DCG-chim stimulation of an acupuncture point Baihui($GV_{20}$) on the Electroencephalogram(EEG). Twenty healthy subject were treated with DCG-chim one time accompanied by the light and vertical pressure and EEG were measured during five minutes for three times (before, during and after treatment). The EEG results of DCG-chim treatment were compared with those of 'Filiform acupuncture(毫鍼)'. Results : EEG power spectra changed significantly after both kind of acupuncture stimulation. Significant increase of $\alpha$ wave and decrease of $\beta$ wave were observed but interestingly, Mid-$\beta$ and SMR of $\beta$ wave which mean the state of concentration were increased with statistically significant. According to these results, DCG-chim stimulation of Baihui($GV_{20}$) seems to lead to relaxation with antianxietic effect and improvement of concentration at the same time. Conclusions : It would be expected that the doctor can apply DCG-chim for treating anxiety, tension, symptom caused by stress and also can use it clinically for patients who have needlphopia or children as a non-invasive procedure. It is suggested that additional studies about the effect of DCG-chim on other acupuncture points and comparison study about the effect of DCG-chim with those of the finger-pressure treatment using other tool should be done in the future.

  • The present study describes the effects of music and vibroacoustic stimuli to the relaxation of human body. We have carried out the experiment on 6 human subjects of which are composed 3 men and 3 women. We have investigated the electroencephalogram(EEG) of all subjects before and after the stimuli of which are made a strong noise or the meditatiom music and the acoustic vibration. The vibroacoustic device has transmitted meditation music as vibration between 20Hz and 250Hz to the body. From the experimental results, we made sure the effects that the meditation music and vibroacoustic stimuli influenced the stress reduction of human body for good as alpha wave was increased continuously during the good stimuli and after that.

  • 본 연구에서는 아로마 화장품의 생리ㆍ심리적 효과를 살펴보았다. 20-30대 건강한 성인 여자를 상으로 스트레스 부하 후 아로마 화장품 사용과 무사용의 두 조건에서 중추 신경계의 뇌파(EEG) 중 Alpha파의 주파수 변동리듬(l/f), 자율신경계(ECG, SKT, GSR) 및 주관적 기분감 평가(POMS) 를 실시하였다. 그 결과, 우전두부의 U파 변동리듬계수의 크기와 변동리듬 경사도를 이용한 쾌적도는 무사용에 비해 아로마 화장품 사용에서 시간이 경과됨에 따라 유의하게 증가하였다(p<0.05). SKT에서는 조건간 유의차는 나타나지 않았으나 GSR에서는 무사용에 비해 아로마 화장풍 사용 후 유의하게 감소하였다(p<0.1). 주관적 기분감 평가(POMS)에서는 무사용에 비해 아로마 화장품 사용 후 성냄, 혼란 항목의 득점이 유의하게 감소하였다(p<0.1). 이상의 결과로부터 스트레스 부하 후 사용한 아로마 화장품의 스트레스 해소 경향 즉 Relax, 진정 효과가 확인되었다.

  • One of principal causes of car accidents is low arousal level of driver. Drivers arrive their destination under an appropriate arousal level. Basic research was done to develop a portable arousal monitor and to evaluate the arousal level of drivers. An arousal monitor which can simulantaneously measure the skin impedance change and EEG was designed and tested. The relationship among three parameters was studied and was used to determine the index of skin impedance level depending on arousal level.

  • 최근 의학 및 게임 분야에서 뉴로 피드백에 관한 연구들이 활발하다. 뉴로 피드백이란 뇌의 전기적 활동을 뜻하는EEG(Electroencephalogram)을 대상으로 하는 바이오피드백(biofeedback) 시스템의 일종이다. 좌 우뇌의 불균형은 불안과 우울 등의 정서적 장애를 초래한다. 본 논문에서는 좌, 우뇌 활성도를 대칭적으로 향상시켜 뇌기능의 최적화를 위한 시스템을 제안하며 뇌파를 분석하여 정서 상태 파악 후 규칙적 훈련을 통한 우울, 불안 등의 정서적 문제를 개선하는 뉴로 피드백 시스템 개발에 대한 결과를 보고한다. 실험을 통한 시스템의 검증으로 3주간 진행한 훈련 결과를 비교하였으며 그 증가율을 살펴보았다. 1주차와 3주차의 데이터를 비교해본 결과 평균적으로 26.18%의 증가율을 보였고 좌, 우뇌의 활성도의 대칭이 향상된 것을 알 수 있었다.
