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.

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.

Purpose: This study explored the validity of a new type of thermometer and parent satisfaction with the new device. This 24-hour continuous monitoring smart wearable wireless thermometer (TempTraq^®) uses a very small semiconductor sensor with a thin patch-like shape. Methods: We obtained 397 sets of TempTraq^® axillary temperatures and tympanic temperatures from 44 pediatric patients. Agreement between the axillary and tympanic measurements, as well as the validity of the TempTraq^® axillary temperatures, were evaluated. Satisfaction surveys were completed by 41 caregivers after the measurements. Results: The TempTraq^® axillary temperatures demonstrated a strong positive correlation with the tympanic temperatures. The Bland-Altman plot and analysis of TempTraq^® axillary temperatures and tympanic temperatures showed that the mean difference was +0.45 ℃, the 95% limits of agreement were -0.57 to +1.46 ℃. Based on a tympanic temperature of 38 ℃, the results of validity of fever detection were sensitivity 0.85 and specificity 0.86. Satisfaction scores for TempTraq^® temperature measurement were all > 4 points (satisfactory). Conclusion: TempTraq^® smart axillary temperature measurement is an appropriate method for measuring children's temperatures since it was highly correlated to tympanic temperatures, had a reliable level of sensitivity and specificity, and could be used safely and conveniently.

The purpose of this study was to compare the ear-based rectal temperature measured with a tympanic thermometer with the rectal temperature measured with a glass mercury thermometer in order to test the accuracy of tympanic thermometer and to determine relationship among rectal, axilla, and abdominal temperature in neonates. The samples consisted of thirty four neonates admitted to the neonatal intensive care unit and nursery at an university affiliated hospital. The mean age of the subjects was 4.9 days. The ear-based rectal temperatures were taken with a tympanic thermometer in rectal mode (First Temp Genius 3000). Rectal and axilla temperatures were taken with a glass mercury thermometer, Abdominal temperature was continuously monitored with the probe connected to the servo controller of incubator. The results of the study can be summarized as follows : 1. Intrarater comparison : Agreement between the first and the second ear-based rectal temperature was 97% within 0.1$^{\circ}C$. 2. Comparison of ear-based rectal temperature and the rectal temperature from a glass mercury thermometer : ear-based rectal temperature ranged from 36.95$^{\circ}C$d to 37.95$^{\circ}C$, with a mean of 37.58$^{\circ}C$(SD＝0.22$^{\circ}C$). Rectal temperature from a glass mercury thermometer ranged from 36.2$0^{\circ}C$ to 37.2$0^{\circ}C$, with a mean 36.75$^{\circ}C$(SD＝0.29). The mean difference between both temperatures was 0.84$^{\circ}C$. The correlation coefficient between both temperatures was r＝0.77(p＝0.00). 3. Comparison of rectal and axilla temperature : Axilla temperature ranged from 35.8$0^{\circ}C$ to 37.1$0^{\circ}C$, with a mean of 36.55$^{\circ}C$. The mean absolute difference between the rectal and axilla temperature was 0.23$^{\circ}C$. The correlation coefficient between rectal and axilla was r＝0.67. 4. Comparison of axilla and abdominal temperature : Abdominal temperature ranged from 36.2$0^{\circ}C$ to 37.0$0^{\circ}C$, with a mean of 36.58$^{\circ}C$. The mean absolute difference between axilla and abdominal temperature was only -0.03$^{\circ}C$. Findings of this study suggest that ear-based rectal temperature overestimates the actual rectal temperatures in neonates. Therefore, the interchangeble use of both temperatures in clinics seems problematic. The site offset(adjustment value) programmed in rectal mode of the tympanic thermometer needs to be readjusted. Choosing one optimal site for temperature measurement for each patient, and using the specific site consistently would result in more consistent measurements of changes in body temperature, and thus can be more effective in diagnosing fever or hypothermia.

Purpose: Infrared thermometers are increasingly used as a convenient, non-invasive assessment method for febrile children. However, the diagnostic accuracy of the infrared thermometer for children has been questioned, particularly in relation to sensitivity and specificity. The aim of this study was to evaluate diagnostic accuracy of infrared thermometers in febrile children. Methods: Articles published between 1966 and 2012 from periodicals indexed in the Ovid Medline, Embase, CINAHL, Cochrane, KoreaMed, NDSL, KERIS and other databases were selected, using the following keywords: 'infrared thermometer'. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4. Results: Nineteen diagnostic studies with high methodological quality, involving 4,304 children, were included. The results of meta-analysis showed that the pooled sensitivity, specificity and AUC (Area Under the Curve) of infrared tympanic thermometers in children over 1 year were 0.80 (95% CI 0.78, 0.81), 0.94 (95% CI 0.93, 0.95) and 0.95 respectively. However the diagnostic accuracy of infrared tympanic thermometers in children with hyperthermia was low. Conclusion: The diagnostic accuracy of infrared tympanic thermometer was similar to axillary and rectal thermometers indicating a need for further research to substantiate these findings in children with hyperthermia.

Body temperature should be measured accurately to assess neonate's condition for proper care. Temperatures measured in rectal, axillary and tympanic site were compared in 129 normal neonates to find out proper nursing time for measuring temperature and the validity of fever detection. The results were as follows : 1. Mean temperatures of axillary and tympanic site($36.85^{\circ}C,\;37.12^{\circ}C$) were significantly lower than those of rectal site($37.19^{\circ}C$). 2. Mean nursing time for measuring body temperature was significantly higher and lower in axillary and tympanic temperatures(159.49 seconds, 11.07 seconds) than in rectal temperature(105.62 seconds). 3. Tympanic and axillary temperatures were significantly correlated with rectal temperature (r=0.85, r=0.78) and the significant correlation was demonstrated between tympanic and axillary temperatures(r=0.76). 4. Sensitivity, specificity, positive and negative predictive values were 0.87, 0.90, 0.72, 0.96 for detecting fever respectively. The above findings indicated that the tympanic thermometer offers a useful alternative to conventional methods.

Purpose: In order to identify the usability of inguinal temperature in a neonatal unit, this study was done to compare inguinal temperature of newborns with rectal, axillary, and tympanic temperatures. Method: Fifty-one normal newborns admitted to the nursery of a university affiliated hospital participated in the study. Tympanic temperatures were taken with a tympanic thermometer. Inguinal, rectal, and axillary temperatures were taken with glass mercury thermometers, and were recorded every 1 minute until the reading remained constant for 2 times. The data were analyzed using the SPSS program. Result: The measurement time for inguinal temperatures in newborns was significantly longer than that for rectal temperatures, but was shorter than that for axillary temperatures. The mean temperature for the newborn's inguinal site was lower than for rectal, axillary, and tympanic temperatures (the lower side), but wasn't different from tympanic temperature (the upper side). The inguinal temperature was significantly correlated with rectal, axillary, and tympanic temperature. The inguinal temperature was not different according to general characteristics of the newborn. Conclusion: These findings indicate that measurement of inguinal temperature is a useful alternative to rectal temperature.

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 verify the usability of tympanic temperature measurement for adults, a comparison of tympanic and axillary temperatures was done. Method: The study was conducted during October 2008, and participants were 110 female nursing students. Axillary temperatures were taken with glass mercury thermometers for 5, 7 and 10 minutes. Tympanic temperatures were taken with Infrared Thermometer IRT 4520 on both ears, twice at a 5-second interval. The data were analyzed using the SPSS 12.0 program. Results: In the 1st measurement, the mean for right tympanic temperatures ($0.06^{\circ}C$) and for left ($0.03^{\circ}C$) were significantly higher than the 2nd. A comparison of mean temperatures for right and left, showed that the mean for the left side on the 1st measurement was significantly higher ($0.01^{\circ}C$) than the right. Also the temperature on left side in the 2nd measurement was higher ($0.04^{\circ}C$) than the right 2nd, but not significantly higher. The mean temperature for right and left tympanic on 1 st and 2nd measurements were significantly higher than axilla for 5 minutes ($0.58^{\circ}C$), for 7 minutes ($0.52^{\circ}C$), and for 10 minutes ($0.43^{\circ}C$). The tympanic temperature was the most closely correlated with the axillary temperature at 10 minutes. Conclusion: Findings indicate that measurement of tympanic temperature is a useful alternative to axillary temperature taken for 10 minutes.
