This research evaluates thermal comfort by comparing the case of maintain cooing temperature of room with the case of raising it at the point of time that human body begins to adapt. An experiment uses constant temperature & humidity chamber 2 places. Pretesting room make up summer season environment, the testing room control by air-conditioner. In condition that maintain temperature of $33^{\circ}C$. The subjects stay in the pretesting room during the 30 minute for the heat storage amount of the normal summertime. The subjects stay in the testing room under each case (case 1: maintaining $24^{\circ}C$, case 2: maintaining $26^{\circ}C$, case 3: up $1^{\circ}C$ after maintaining $24^{\circ}C$ during 30 minute, case 4: up $1^{\circ}C$ after maintaining $26^{\circ}C$ during 40 minute). 1. Result of comparison of case 1 and case 2 appears that thermal sensitive vote examine from slight cool to cool and thermal comfort examine slight comfort by temperature rise at human body adaptation point of time.2. Test of case 3 and case 4 appear similar value at thermal sensitive vote and thermal comfort.3. Through the case 2 and case 4, continuous thermal comfort maintain at $24^{\circ}C$, if raise $26^{\circ}C$, same thermal comfort maintain after a human body adaptation temperature rising effect bring energy saving.

Using the 2-channel DROS SQUID (Korea Research Institute of Standards of Science, 1999), the present study was carried out to record changes elicited in the auditory cortex by acupuncture stimulus (right GB43, Xiaxi). Needle-retention and manual needle-twitching stimulation of GB43 and SP1 were done for acquiring the brain activities changed by acupuncture. Acupoint GB43 is known to be effective for the treatment of ear-related disease, such as deafness and tinnitus, and to be suspected to be related to the auditory cortex. Auditory evoked magnetic fields were recorded from the left hemisphere of five or four subjects, in response to contralateral ear stimulation by irregularly spaced 170msec long 1kHz tone busts (Korea Research Institute of Standards of Science). The result as follows The latency and amplitude of SQUID MEG responses at the human auditory cortex changed by needle-retention condition on GB43 were 7.2msec and 1.617, respectively, which were slower and larger than those of no-acupuncture condition. The amplitude of SQUID MEG responses at the human auditory cortex changed by needle-twitching condition on GB43 was 13.517, which was larger than that of no-acupuncture condition. The change in SP1 following GB43 needle-twitching condition were not observed in latency. The amplitude changed by needle-twitching condition on SP1 was 12.2fT, which was not significant. These results suggested that auditory cortex can be affected by acupuncture stimulus, though not specific or significant because of small number of subjects.
