Background and Purpose : There have been many studys about the relationship between the meridians and the acupoints of the twelve meridians, but no study about the extra points. To verify Dong-Shi acupoints, a kind of extra points, we studied the effects on the thermal changes of the ankle region following acupuncture on the Wu-Hu. Object and Methods : This study was researched into clinical statistics for 45 healthy normal students. The object was divided into two groups. One was the control group and the other was the acupuncture group. The acupuncture group was divided into two groups ; ACU-up : The class of ascent thermal change among acupuncture group. ACU-dn : The class of descent thermal change among acupuncture group. First, in the control group, we took a picture at the ankle region(BL60, BL62, GB40, ST41) without any stimulation with the Digital Infrared Thermal Imaging System and did after 10 minutes respectively. Second, in the acupuncture group, we took a picture without any stimulation and then acupuncture on Wu-Hu and took a picture after 10 minutes in the same way respectively. Results : 1. In the control group, average thermal change of BL60, BL62, GB40 and ST41 was decreased(about $0.2^{\circ}C$) after 10 minutes. 2. The skin temperature of all measured parts was significantly lower in the ACU-dn group after 10 minutes. 3. There were no significant differences of thermal change between the control and the acupuncture group, between the control and ACU-up group after 10 minutes. Conclusion : This result indicated that the acupuncture on the Wu-Hu was effective at the ankle region. And so the more study is needed continuously.

Background: To study the role of spinal alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptors in pain behaviors caused by mild burn, we examined the effect of intrathecal administered ACEA 2085, which has been recently characterized as a high potency competitive AMPA receptor antagonist, on the thermal hyperalgesia state induced by mild burn. Methods: A thermal injury was induced by applying the left hind paw to a thermal surface ($52.5^{\circ}C$) for 45 sec. Thermal escape latency of the hind paw was determined using an underglass thermal stimulus. Thirty min after thermal injury, the paw withdrawal latency (PWL) in injured paw of all groups fell from 10~12 sec to 5~7 sec. At that time, ACEA 2085 (0.01~0.1 mcg) and 6-cyano-7-nitroquinoxalinedione (CNQX, 1~30 mcg) were injected through intrathecal heters in rats with mild burn injury on the right hindpaw. And then, PWL were measured in the both hindpaw every 30 minutes for about three hours. Results: The intrathecal injection of ACEA 2085 produced a dose dependent reversal of the hyperalgesia in the right hindpaw and more potent than CNQX, but had no effect upon the response latency of the normal left hind paw even at the largest doses. All effects were observed at doses that had no significant effect upon motor function. Conclusions: Intrathecal ACEA 2085, highly selective AMPA receptor antagonist produce a dose- dependent reversal of the thermal hyperalgesia evoked mild burn injury. These results suggested that spinal AMPA receptor play an important role in the hyperalgesia induced by mild burn injury.

We report the recent reliability test results of SpatiaLight's liquid crystal on Silicon (LCOS) microdisplays. Two different types of reliability tests have been performed: 1) thermal and 2) thermal with high intensity UV light. Various important device parameters were regularly monitored including the contrast ratio, color uniformity, and switching time. The test data shows that there are no degradations that fail the pass criteria. Lifetime estimations are given from the test data.

Radiolysis of polyacrylonitrile(PAN) has been studied. Parameters for crosslinking and scission induced by gamma-ray irradiation were obtained by means of sol-gel partitioning method. G-value of crosslinking in PAN ($\bar{M}n=6{\times}10^5$) was 0.038 and the gel dose 21.6 Mrad. The effects of irradiation on the thermal degradation rate in PAN was also studied. No appreciable changes in thermal degradation rate observed up to 81.8 Mrad of irradiation dose.

The present study discusses the deviation from the pure dead-time model of passive scalars such as temperature and concentration in the Poiseulle flow Even in the case of no thermal diffusion, there exists a substantial amount of damping and large deviation of phase lag from that computed by the traditional dead-time model after only 10 diameter downstream. These are caused by the phase difference of temperature in the radial direction due to the nonuniform velocity distribution. In the presence of thermal diffusion, damping is more pronounced.

The purpose of this Study was to determine thermal sensation and physiological responses for men in summer indoor environment, under various air temperature and relative humidity, with male university students. Subjective Evaluation, Heart Rate Variability(HRV), Electroencephalogram(EEG) were examined. We found that comfort of people was achieved at 50% R.H., 24C, and the difference of skin temperature was found at the calf area as air temperature changes. At low air temperature and low humidity, heart rate was decreased, but there was no change at brain wave, keeping a-wave.

Adorption of nitric oxide on the Pt(III) surface sputtered by Ar-ion has been studied using thermal desorption spectroscopy and Auger electron spectroscopy. Ar-ion sputtering creates a precursor state of ($NO\beta$ stage) adsorbe dat defect sites. The precursor state is characterized by the terminal bent species . At low coverge mos 샐 adsorbed NO dissociates . And as increasing the coverage, the fraction of dissociation remains about 80%.

The organic yields (i.e. fraction of nuclear events resulting in organic compound formation) of the radioative neutron capture reactions of halogens in purified bromobenzene have been determined varying extraction time, at $100^{\circ}C$ for thermal effect, varying irradiation time, varying neutron flux and with additional U. V. irradiation. Among the important results are; (1) The organic yields show no remarkable fluctuations with time following neutron irradiation; (2) The organic yields show no change with thermal energy; (3) The organic yields of degassed samples are same in different length of irradiation time whereas the yields of the samples in open air appear to increase with increasing time of irradiation (4) The organic yields increase remarkably with increased neutron flux; (5) The organic yields show a sharp increase by additional U. V. irradiation after neutron irradiation.

This study is focused on the effect of thermal load according to the various plan types in tower-type apartment in Korea. So, we chose the '』' type model in order to analyze the shading effect of the plan type. The main results are as follows. In chosen model, cooling energy demands are more sensitive than heating ones when is compared with the two methods. And there are about 10% deviations between new and conventional method. Because new method considers more detailed than conventional one about the building geometries. We also found that this building type affects to the about 3 floors from the top and it doesn't affect to the thermal load in lower floors. From these facts, we suggest new modeling method to the similar researches that will be analyzed the thermal load on the tower type apartment in Korea. Also there is no difference of the thermal load in each azimuth between simple and detailed modeling method. Consequently, we judge that this new method considered the shading effect will be used a lot to the similar analysis in tower type apartment in Korea.
