This study was undertaken to examine the effects of acupuncture at LI4 on temperature changes of the facial surface randomly divided into 17 areas. The volunteers who participating in this study had taken rest for 20 - 30 min in room temperature ($23-25^{\circ}C$) before acupuncture and informed them what to prohibit smoking, drinking and drug for the previous one day. The Temperature of facial surface was measured by using Digital Thermography IR 2000 (Meridian Co., Korea) at 5 min before and immediately, 5, 10, and 15 min after acupuncture on LI4. The results of this study showed that there was no significancy in thermal changes of facial surface randomly divided into 17 areas, but different significantly in the aggregate changes at the difference of the thermal changes on facial surface (p < 0.001). The difference of aggregate change was increased time-dependent and the changes at 1st, 3rd, and 13th area were comparatively smaller than the other areas. However, the changes at 6th, 8th, 10th and 15th area were more increased than the others. This study suggests that acupuncture at LI 4 help human being increase the reaction to maintain thermal homeostasis in facial surface and the ability to treat at these area's disease.

Objective: The purpose of this study was to identify through infrared thermal imaging technology the facial surface temperature (FST) of laying hens in response to the variations in their thermal environment, and to identify the regional differences in FST to determine the most stable and reliable facial regions for monitoring of thermoregulatory status in chickens. Methods: Thirty Hy-Line Brown hens (25-week-old) were sequentially exposed to three different thermal conditions; optimal (OT, 22℃±2℃), low (LT, 10℃±4℃), and high temperature (HT, 30℃±2℃). The mean values of FST in five facial regions including around the eyes, earlobes, wattles, beak and nose, and comb were recorded through infrared thermography. The maximum FST (MFST) was also identified among the five face-selective regions, and its relationship with temperature-humidity index (THI) was established to identify the range of MFST in response to the variations in their thermal environment. Results: Hens exposed to OT condition at 15:00 displayed a higher temperature at wattles and around the eyes compared to other regions (p<0.001). However, under LT condition at 05:00 to 08:00, around the eyes surface temperature showed the highest value (p<0.01). In HT, wattles temperature tended to show the highest temperature over almost time intervals. Main distribution regions of MFST were wattles (63.3%) and around the eyes (16.7%) in OT, around the eyes (50%) in LT, and wattles (62.2%) and comb (18.3%) in HT. The regression equation between MFST and THI was estimated as MFST = 35.37+0.2383×THI (R² = 0.44; p<0.001). Conclusion: The FST and the frequency of MFST in each facial region of laying hens responded sensitively to the variations in the thermal environment. The findings of this experiment provide useful information about the effect of the thermal conditions on the specific facial regions, thus offering an opportunity to stress and welfare assessment in poultry research and industry.

Objectives and Backgrounds : After parotidectomy, some of patients complain gustatory sweating, facial flushing and discomfort in the same area. A series of these symptoms are supposed to be caused by the aberrant regeneration of the secretory parasympathetic fibers to sweat glands and blood vessels of the skin following parotidectomy. In this study, we want to compare the efficacy of thermography to the Minor's starch-iodine test for determining the presence of Frey's syndrome. Materials and Methods : 48 patients who underwent total or superficial parotidectomy from March 2002 to December 2004 were selected for this study. A subjective clinical questionnaire and the objective Minor's starchiodine test were performed to evaluate the incidence of this syndrome. Total 21 patients were confirmed as positive Frey's syndrome and infrared thermography was performed for them. Result : Frey's syndrome occurred in 21 patients(43.8%). The average temperature of parotidectomy site and normal opposite area were $27.65^{\circ}C\;and\;26.41^{\circ}C$ respectively. Thermography showed temperature difference in 20 patient(95.2%) and the difference of temperature was statistically significant above $1.0^{\circ}C$(p<0.001). The severity of symptoms were related with the difference of temperature(p<0.05). Conclusion : Thermography is useful, non-invasive, simple and quantifying method to diagnose Frey's syndrome. Additionally, this geographic diagnosis is available to show the accurate area for botulinum toxin injection.

This study reviews studies that used skin temperature in order to establish an emotion evaluation protocol based on skin temperature for home appliances. A survey of skin temperature evaluation papers was conducted by the following five stages: (1) keyword search, (2) title screening, (3) abstract screening, (4) full paper screening, and (5) relevance evaluation. Selected papers were reviewed for: purpose, recruitment criteria of participants, the number of participants, apparatus, procedure, measures, analysis methods, and major findings. Thermistor sensors and thermography are used for the measurement of skin temperature. Skin temperature sensors are attached to 4 - 10 locations on the body and their mean of skin temperature is calculated by Ramanatan's 4-point or Hardy & Dubois's 7-point method. Semantic differential (SD) method and thermography measuring facial surface temperature have been used for emotion evaluation. The SD method provides a set of adjective pairs related to a product and evaluates changes in emotion from the use of the product. The range of facial surface analyzed is defined in the thermal image and temperature changes before and after the evaluation are analyzed. The evaluation items of home appliances include form, color, material, aesthetics, satisfaction, novelty, convenience, pleasantness, and excellence. Many existing emotion studies using skin temperature do not apply physiological and psychological methods. This study provides basic data to establish a skin temperature and emotion evaluation protocol by examining literature for skin temperature and evaluation of sensitivity.

많은 연구에서 정서 특정적 생리 반응을 밝히기 위하여 심박률, 혈류량, 피부전도 반응 등의 지표를 사용하였으나, 안면온도를 이용한 정서 연구는 많지 않다. 본 연구는 적외선 열화상을 통해 공포 및 기쁨 자극에 대한 안면온도 변화를 관찰하고자 한다. 98명의 대학생과 중고생을 대상으로 공포 또는 기쁨을 유발하는 자극을 제시하기 전과 후의 안면온도를 측정하였다. 온도값은 이마, 눈앞, 콧등, 코끝, 그리고 뺨에서 추출하였다. 공포자극을 제시한 조건에서는 콧등과 코끝의 온도가 유의하게 낮아졌다. 기쁨 자극을 제시한 조건에서는 이마, 눈앞의 온도 상승이 유의하였으며, 코끝에서 온도가 유의하게 낮아졌다. 두 조건에서 코의 온도가 유의하게 낮아졌는데, 이는 공포 또는 기쁨을 경험할 때 각성수준이 증가하여 코 혈관의 혈류량이 감소함으로써 온도가 낮아진 것으로 볼 수 있다. 공포나 기쁨을 경험할 때 나타나는 온도 변화는 정서를 경험할 때 손가락온도를 측정한 선행 연구결과와 일치한다. 이런 연구결과는 정서 측정기법의 개발과, 인간의 정서를 탐지하는 컴퓨터 시스템의 기초를 확립하는데 기여하는 바가 있을 것이다.

Background: A stellate ganglion block (SGB) causes increased blood flow in the maxillofacial region, exhibiting the potential for regenerative effects in damaged tissue. The focus of this study was to understand the efficacy of SGB for regenerative effects against nerve damage. A rat model of the superior cervical ganglion block (SCGB) was created instead of SGB, and facial blood flow, as well as sympathetic nervous system function, were measured. Methods: A vertical incision was made on the left side of the neck of a Wistar rat, and a 5-mm resection of the superior cervical ganglion was performed at the back of the bifurcation of the internal and external branches of the left common carotid artery. Blood flow in the skin at the mandibular angle and mean facial temperature were measured using a laser-Doppler blood flow meter and a thermographic camera, respectively, over a 5-week period after the block. In addition, the degree of ptosis and miosis were assessed over a period of 6 months. Results: The SCGB rat showed significantly higher blood flow at the mandibular angle on the block side (P < 0.05) for 3 weeks, and significantly higher skin temperature (P < 0.05) for 1 week after the block. In the SCGB rat, ptosis and miosis occurred immediately after the block, and persisted even 6 months later. Conclusions: SCGB in rats can cause an increase in the blood flow that persists over 3 weeks.

The aim of this study was to investigate that thermal imaging is objective and effective to evaluate the severity of Bell's palsy. We investigated 19 cases of patients in college of Oriental Medicine, Iksan Oriental medical hospital at Wonkwang university who were diagnosed with Bell's palsy. The degree of palsy was evaluated with House-Brackmann grading system(HBGS) before treatment, then the thermal difference of the face was calculated by thermal imaging, and finally the correlation between HBGS and thermal difference was analyzed. The significance correlation was found between HBGS and thermal imaging's thermal difference. According to the images taken from 17 patients' DITI's temperature value and HBGS's palsy grade, they significantly were correlated. As thermal imaging's thermal differences got larger in number, the palsy grade had increased. These results suggest that thermal imaging identified to be a relatively objective examination method for evaluating the severity of Bell's palsy.
