Purpose : The presence and degree of fever in children is a useful indicator of illness. This project aimed to assess the accuracy and usefulness of infrared tympanic membrane(TM) & forehead feverscan thermometers for measuring children's temperatures. Methods : Data were obtained from 1,050 children with a median age of 4.5 years. They visited the pediatric clinics at Chung-Ang University Yongsan Hospital from January 2004 to December 2004. We measured body temperatures at axilla by mercury thermometer, at ear by infrared TM thermometer and at forehead by feverscan. Then we analyzed the correlation between these data. Results : Mercury and TM thermometer, and Mercury and forehead feverscan thermometer very well correlated with each others(P<0.05). And the sensitivity of infrared TM thermometer(right and left) to correctly identify febrile children was 81.1 percent and 82.4 percent, the positive predictive value to detect a fever was 81.8 percent and 73.6 percent. The sensitivity of forehead feverscan was 83.3 percent and the positive predictive value was 74.4 percent. Conclusion : The tympanic membrane temperature measured by the BRAUN IRT $3020^{(R)}$ and forehead arterial temperature measured by the HubDIC $DOTORY^{(R)}$ feverscan accurately reflects mercury axillary temperature, validly assesses the presence of fever in children, and is easy to use. The Braun IRT $3020^{(R)}$ & HubDIC $DOTORY^{(R)}$ therefore is an adequate tool to assess fever and may be used both in a clinical setting and for research purposes.

Purpose : To examine the effect of unilateral otitis media and unilateral cerumen occlusion of the ear canal on thermometers. Methods : One hundred eighty six children with unilateral otitis media, fifty children with unilateral cerumen occlusion, and fifty children with neither otitis media nor cerumen were enrolled. Temperature was measured in both ear canals using thermometers. After 15 minutes, second temperature was measured again in both ears. Unilateral otitis media was graded by video otoscope for 7 grades. Differences in temperatures between affected ears and unaffected ears were analyzed. Results : No temperature difference between the normal and cerumen groups was observed. The mean temperature of the otitis media ear canal was $0.13{\pm}0.20^{\circ}C$ higher than that of the intact ear canal ($36.99{\pm}0.54^{\circ}C$ vs $36.86{\pm}0.52^{\circ}C$; P<0.001). There was no statistically significant temperature difference between grades. Conclusion : Unilateral otits media can affect estimation of body temperature measured by thermometers.

체온은 가장 기본적인 진단 정보로써 여러 가지 생리 변화를 반영하는 지표이므로 거의 모든 질환에 대해 반드시 측정하도록 되어있다. 그러므로 체온을 정확하고 빠르게 측정하는 것은 매우 중요하다. 본 논문은 복합형 체온측정 시스템의 개발에 목적이 있다. 즉, 하나의 복합 시스템으로 고막과 이마에서의 체온을 측정하려고 한다. 개발 결과, 이 시스템은 IR 센서를 사용한 비접촉식 방식이며 빠른 응답시간과 $0.2^{\circ}C$의 정밀도를 가지고 있다. 또한 체온 측정을 위한 주변온도 보상을 고려하여 온도 측정의 정확도를 높였다.

This study aims to provide a better nursing service in the dimension of economizing time and human efforts. This is to present some basic knowledge necessary to improving a nursing quality in measuring body temperature by analyzing the contents that the objects experienced at the time of measure with tympanic thermometer and mercury thermometer Subjects of the survey consisted of 71 college students, 47 adult patients and 40 pediatric patients. The results were as follows : 1. The oral temperature by mercury thermometer and tympanic thermometer with oral mode was : $36.83^{\circ}C$ by mercury thermometer and $37.02^{\circ}C$ by tympanic thermometer in college students : it showed an significant difference statistically. 2. Comparsion between oral mode and rectal mode by tympanic thermometer in college students : $37.03^{\circ}C$ by oral mode and $37.55^{\circ}C$ by rectal mode and this defference was significant statistically 3. Comparision between rectal temperature by mercury thermometer and rectal mode of tympanic thermometer : $37.54^{\circ}C$ by mercury thermometer and $37.73^{\circ}C$ by tympanic thermometer, it showed a significant difference statistically. 4. Comparision between oral temperature by mercury thermometer and oral mode of tympanic thermometer of the pediatric patients : $36.51^{\circ}C$ by mercury temperature and $36.94^{\circ}C$ by tympanic thermometer, it showed a significant difference statistically. 5. Comparision between oral body temperature by mercury thermometer and oral mode of tympanic thermometer of the adult patients : $36.56^{\circ}C$ by mercury thermometer and $36.90^{\circ}C$ by tympanic thermometer, it did not show statistically any difference. 6. At the measure by mercury thermometer this data can classified In three main categorise : their feeling to a thermometer, thermometer itself and aspect physical of the clients. It is considered that an subjective experience to tympanic thermometer was more positive.

Flap monitoring is important for flap salvage. Although there are many methods to observe the flap, practical methods mostly used are subjective methods. Recording flap surface temperature is one of the objective methods of flap monitoring. We used an infra-red thermometer to simplify monitoring of the flap temperature. 60 groin flaps of SD rats are used in the experiment. Artificial arterial or venous insufficiency was made and the surface temperature was checked and compared with body temperature. In the results, the temperature of the arterial clamped flaps was lower than that of body and the mean difference was $0.3^{\circ}C$ after 20 minutes of clamping. In the vein-clamped flaps, the mean decrease was $0.4^{\circ}C$ after 30 minutes of clamping. The all difference of the temperature between the flaps and body was statistically significant. Our results suggest that flap monitoring by infra-red thermometer is simple, useful and helpful to evaluate the flap status.

This study was to investigate the method for shortening the body temperature (BT) because it takes a long time and is impractical to measure axillary or oral BT with mercury thermometer, The first approach was to identify BT change according to the measuring time and determine the clinically not statistically avaiable and optimal BT measuring time. The second was to test the accuracy of tympanic thermometer. It can measure BT within a few seconds, so if it is approved accurate, we can save BT measuring time by substitute tympanic thermometer for mercury thermometer. This study was conducted from 1, to 30 June, 1996. The subjects were 12men students of medicalk college and 29 women students of nursing school. The results were as follows ; 1) The 3, 5, 7, 9, 11, 13minute-measured axillary BT and 3, 5, 7, minute-measured BT showed somewhat linear relationship with time. It was difficult to find the optimum measuring time which were clinically significant. 2) For axillary tempeiature, the measuring time which were not statistically different was 11 and 13minute. But the real BT difference between 3 and 13minute, or between 5 and 13minute were very small and was within the range of daily variation. 3) For oral temperature, there was no intervals which showed the statistically insignificant. But like as axillary temperature, the difference between 3 and 7, or 5 and 7 minute were trivial by $0.3^{\circ}C$ and by $0.1^{\circ}C$ respectively. 4) Tympanic temperatures were lower than oral BTs which were measured with mercury thermometer by $0.26^{\circ}C$ (with ear tug) and $0.15^{\circ}C$(without ear tug). 5) The reliability of repeated measure tympanic temperature was better than without ear tug. With above results, we can't determine the optimal and cilically significant oral and axillary measuring time using mercury thermometer. However, because the real differences between measuring times were very small, so we recommend further study for the aged, the infants and the febrile patients. And we can't sure the accuracy of tympanic temperature but the reliability was better with ear tug than without ear tug.
