건물의 실내온도가 유아교육시 인지성능 개선에 미치는 영향

Abstract

To improve the cognitive performance of preschool, children's electroencephalogram(EEG), concentration level and heart rate variability(HRV) are measured while changing the temperature to 18[°C], 21[°C], 24[°C], 27[°C] and 31[°C] in the test room set as relative humidity 50[RH%], air speed 0.02[m/sec] and illumination 1000[lux]. Measurement condition is uniformly set as 1met of activity while seated and relaxing with the cloth amount of 1.05[clo]. As a result, it was found that sα increased by 40% when the subject was in 24[°C] compared to 31[°C]. Concentration increased by 10[%] under 24[°C] compared to 31[°C]. The standard deviation of normal to normal intervals(SDNN) decreased 12[%] under 24[°C] compared to 31[°C]. Also, aggression decreased by 12[%] under 24[°C] compared to 31[°C]. Therefore, it can be concluded that comfortability and cognitive ability improves under mild temperature such as 21∼24 [°C] better than warm temperature of over 27[°C].
