Development of an assessment method using the fluctuation analysis on eeg and ecg for application in a comfortable environment.

1.我们利用心理生理模型建立了一个稳定的实验系统。考虑到在医院和/或设施中的临床应用，我们牢记这三点。1）易于测量，对受试者的不便最小2）易于移动3）无需良好的屏蔽条件即可测量。考虑到上述几点，我们确定由干电池供电的便携式EEG和/或ECG设备是最好的。我们能够使用“生物信息观测系统”（KISSEI COMTEC）快速轻松地在线分析所有数据。从热水浴时脑电图的实验结果来看，我们发现在热水浴（约41摄氏度）期间显示出皮层激活。另外，我们认为波动分析的结果与舒适度等主观感受之间有很好的相关性.我们研究了在声音刺激过程中心率或呼吸速率与舒适感或警觉性之间的关系。心率变异性（HRV）与舒适度主观评价之间存在良好的相关性，提示HRV可作为舒适度的评价工具.我们在日本护理研究学会杂志和国际生物统计学杂志上发表了一些数据。

1. We established a stable experimental system using the psycho-physiological model. In consideration of applying it clinically in hospitals and / or faclilities, we bore these three points in mind.1) easily measurable, and minimum inconvenience to subjects2) easily removable3) measurable without good shielding conditionWith the above mentioned points in mind, we established that portable equipment for EEG and / or ECG which were powered by dry cells were the best for these purposes. We were able to analyze all data on-line speedily and easily using a "Bio-information Observing System" (KISSEI COMTEC).2. From the results of experiments in EEG during a hot bath, we found that a cortical activation was shown during a hot-bath (about 41ﾟC). Additionanlly, we suggested that there was a good relationship between the results of fluctuation analysis and subjective perception like comfort.3. We examinde a relationship between heart rates or respiratory retes and sensation of comfort or alertness during sound stimulation. There was a good correlation between the heart rate variability(HRV) and subjective assessment of comfort, suggesting that HRV was useful as an assessment tool of amenity.4. We published some of these data in the Journal of Japanese Society of Nursing Research and the International Journal of Biometeorology.
