  • In this paper the automatic system for dairy cattle has been desisted such as body temperature measuring unit, feed supplying unit and temperature control unit. Since e disease is strongly related to the body temperature of cattle, early detection of the abnormal temperature would prevent the severe problems which nay occur in dairy farms. An electronic component AD590J is used as temperature sensor for the system, The device is highly robust against the noise since the output signal is the current so it can be applied to a long distance sensing The resolution of signal is 0.1$^{\circ}C$ and the current is 10㎷ Also 12-bit A/D converter is desisted fir interfacing the sensor with a one-chip microprocessor. A temperature measuring experiment using the developed system has been done for measuring the temperature of human beings and the system was proven to be useful for measuring the body temperature of dairy cattle properly. A geared AC motor is used for the feed supplying unit The heater and fm are used as temperature control unit. The feed supplying unit and temperature control unit are well operating in the laboratory experiment.

  • With regard to the fact that temperature of human body remains almost constant at $37^{\circ}C$, changes by circadian variation, this study intended to investigate the effect of circadian rhythm on physiological responses of human body according to body fat rate. Fifteen healthy adult women were recruited for this study and were measured body fat as a method of bio impedance. We organized subjects into three groups ; low body fat group(group L-less than 20% of body fat), medium body fat group(group M-20%~30% of body fat) and high body fat group(group H-more than 30% of body fat). The experiment was carried out in a climate chamber of $32^{\circ}C$, 60% RH with the repeat of 'Exercise' and 'Rest' period. Subjects participated in two experiments, one is morning experiment(called 'AM'), the other is afternoon experiment (called 'PM'). The results of this study are as follows ; As to the variation of rectal temperature, group L and M had a significant difference in the time of the day between AM and PM, but group H had almost the same rectal temperature in the two kinds of experimental time. The reason why group H had a smaller difference in the circadian rhythm of rectal temperature in this study is estimated at the Budd et al.(1991)'s results that body fat had effects on reduction in thermogenesis, radiation, mean skin temperature, and increase in insulation of the tissues. Group M had the highest mean skin temperature in the 'PM'. All the 3 groups didn't have stable values in 'AM'. But it showed more stable in 'PM' than 'AM'. Sweat rate was the highest in group H in both 'AM' and 'PM'. Group M had larger sweat rate in 'PM' than 'AM'. but in group L and H, sweat rate was almost the same in two kinds of time of the day. This result suggests that who have more or less body fat have larger difference in sweat rate between morning and afternoon than who have normal body fat.

  • Purpose: influence of benzodiazepine (midazolam)or cholinergic inhibitor (atropine or glycopyrrlate) on intra-operative body temperature remains unclear and controversial. This study compares intra-operative body temperature in 50 abdominal surgical patients under general anesthesia between the administration of midazolam and glycopyrrolate in combination, or glycopyrrolate alone. Methods: Patients who underwent abdominal surgery were recruited from September 2008 through October 2009 at Gachon University Gil hospital in incheon. Core body temperature was measured in the right ear using a tympanic membrane thermometer at induction of general anesthesia and at 1 hr, 2 hr, and 3 hr after induction. Results: There were no differences in core body temperature at any measurement point between either patient group (F=1.08, $p$=.377). Core body temperature decreased throughout the 3 hr after induction in both groups (F=9.22, $p$ <.001). Specially, core temperatures at induction of general anesthesia (p<.001), 1 hr (p<.001), 2 hr ($p$ <.001), and 3 hr ($p$ <.001) after induction were lower than before administration of midazolam and glycopyrrolate, or glycopyrrolate alone. Conclusion: We conclude that a cholinergic inhibitor (glycopyrrolate, 0.1 mg) therefore seems not to affect intra-operative body temperature of patients given a benzodiazepine (midazolam, 0.04 mg $kg^{-1}$), and not to increase body temperature in patients not given a benzodiazepine during the 3 hr after the induction of general anesthesia. Intra-operative warming therefore is needed to prevent hypothermia in surgical patients who receive pre-operative administration of midazolam and/or glycopyrrolate.

  • The purpose of this study is to observe the effects of ice-pack application on different body areas and to note which body area produces the best results according to age, room temperature, sex and disease. Seventeen patients, including six men and eleven women, hospitalized at Seoul National University Hospital from May 22 to August 29, 1971, ranging in age from 15 through 60 years with an oral temperature of 38℃ or over, were chosen for this study. They were observed with regard to the effect of the ice-packs after applications for 30, 45 or 60 minutes. Four ice-packs, 7.6inch by 9 inch, were applied on the chest and the abdominal surface in the control group and the same size and number of packs on the axillae and political regions in the experimental group. The study results were reviewed in a statistical method to obtain the following findings 1. There was no significant difference in the change of the body temperature between the control group and the experimental group after applying the packs for 30, 45 or 60 minutes. 2. Individually, there was a significant difference in the change of body temperature between before and after application for 30, 45 or 60 minutes. 3. The difference of room temperature also had no merle influence on the body temperature taken immediately before applying the ice-packs. Even when ice-packs were applied for 30, 45 or 60 minutes, the room temperature did not influence the reduction of temperature in the patient. 4. There was a significant difference in the change of the body temperature, according to the sex, after application for 30, 45 or 60 minutes. Male patient's body temperature decreased far more noticeably than the female patients and the degree of reduction became more pronounced the longer the packs were applied. 5. In regard to age, in adults, the degree of reduction in the body temperature by the application of ice-packs was similar after appling them for 30, 45 or 60 minutes and did not depend upon the length of application. 6. Regardless of the disease, there was no great difference in the reduction of body temperature when the ice-packs were applied for 30 or 45 minutes, except for patients with typhoid fever when a striking decrease in the fever resulted after a 60 minute application of the ice-pack.

  • Purpose: In this study changes were observed in body temperature, heart rate and arterial oxygen saturation (SaO2) of newborns after bathing and to determine the effects of covering their heads with cotton hats after bathing. Methods: Participants were 58 newborn infants, 31 in the experimental group had their heads covered with cotton hats after their bath while 27 in the control group did not. Body temperature, arterial oxygen saturation and heart rate were measured at 8 consecutive times after bathing. Data were analyzed using t-test and repeated measures ANOVA. Results: Body temperature declined shortly after bathing. The experimental group showed faster recovery (p<.001). Heart rate increased after bathing in both groups. Heart rate in the experimental group decreased for 120 minutes and gradually increased to baseline (p<.001). In the control group, heart rate decreased for 180 minutes and then increased but did not reach the baseline (p<.001). Arterial oxygen saturation decreased shortly after bathing and recovery to the baseline was more rapid in the experimental group (30 minutes vs. 60 minutes) (p<.001). Conclusion: With significant changes observed in newborns' body temperature, arterial oxygen saturation and heart rate, covering the head right after bathing is effective in stabilizing infants' physiological system.

  • The purpose of this study was to design functional clothing based on the physical characteristics of old women. The subjects of this experiment were 5 healthy old women and 5 college women. While the subjects were exposed to the circumstances of $28{\pm}0.5^{\circ}C$ and local heating at 7 areas (chest, abdomen, back, loin, hand, thigh and instep), their skin temperature, physiological reaction and psychological reaction were determined. The conclusions about the effects of local heating are as follows : 1. Skin temperature before heating was in the order of head-neck> trunk> upper limbs> lower limbs (Group A: old subjects) and head-neck> trunk> lower limbs> upper limbs (Group B: young subjects). 2. The heating pad was attached and detached for 30 minutes each. The sharpest rise and fall were recorded at 5 minutes with the pad on and off. Both groups had great changes in the body parts near trunk. 3. With the pad on and off, both groups showed no change in body temperature, blood pressure, and pulse rate. 4. Concerning the pervasive effects of local heating on whole body skin temperature, loin heating greatly increased other body parts in Group A. In Group B, the effects were large in heating chest, abdomen, back, loin, and thigh. 5. The loin part of old women has the greatest pervasive effect of local body heating.

  • Continuous monitoring of intracranial pressure is a well established medical procedure. Still, little is known about long-term behavior of intracranial pressure in normal pressure hydrocephalus. The present study is designed to evaluate periodicity of intracranial pressure over long-time scales using intraventricular pressure monitoring in patients with normal pressure hydrocephalus. In addition, the circadian and diurnal patterns of blood pressure and body temperature in those patients are studied. Four patients, selected with "probable" normal pressure hydrocephalus, were monitored for several dozen hours. Intracranial pressure, blood pressure, and body temperature were recorded hourly. Autocorrelation functions were calculated and cross-correlation analysis were carried out to study all the time-series data. Autocorrelation results show that intracranial pressure, blood pressure, and body temperature values follow bimodal (positive and negative) curves over a day. The cross-correlation functions demonstrate causal relationships between intracranial pressure, blood pressure, and body temperature. The results show that long-term fluctuations in intracranial pressure exhibit cyclical patterns with periods of about 24 hours. Continuous intracranial pressure recording in "probable" normal pressure hydrocephalus patients reveals circadian fluctuations not related to the day and night cycle. These fluctuations are causally related to changes in blood pressure and body temperature. The present study reveals the complete loss of the diurnal blood pressure and body temperature rhythmicities in patients with "probable" normal pressure hydrocephalus.

  • Purpose : The purpose of the research was to analyze foot pressure, foot temperature, and correlation between foot pressure and foot temperature to grasp impact on foot pressure and body temperature distribution chart depending on functional difference of leg length. Method : After measuring leg length, put 15 students whose functional difference of leg length was over 10mm to difference group and 15 students whose functional difference of leg length was under 5mm to normal group and categorize soles of foot into 6 sections of hallux head, 1st metatarsal head, 2-4 metatarsal head, 5 metatarsal head, lateral heel, and then measure by foot pressure analyzer to analyze characteristic of pressure distribution and classify into front of the lower leg, back of the lower leg, soles of foot and measure by body temperature analyzer to analyze by checking body temperature. Result : Weight difference depending on foot pressure and body temperature was bigger when functional difference of leg length was bigger, and it could be confirmed that foot pressure and body temperature of short leg side were higher than those of short leg side. Thus, if difference exists in leg length, weight load on short leg side increases which results in higher foot pressure and body temperature, therefore enabling an assumption that mechanical problem will occur in short leg. Conclusion : When functional leg length inequality, weight bearing and pressure was getting high as a result, temperature was getting high in short leg.

  • There are numerous studies on relations between sleep and environmental factors such as noise, illumination and thermal conditions. Sleep is affected by the thermal environment. This study describes influence of thermal environment on skin temperature, sleep patterns and body movements using physiological and psychological measurements. The results are as follows: 1) The fluctuations of room temperature during sleep appeared skin temperature variations. The more room temperature is high, the more skin temperature is high in 22$^{\circ}C$, 26$^{\circ}C$, 30$^{\circ}C$. 2) A significant relation between body movement and skin temperature was found within room temperature. Under room temperature conditions of 22$^{\circ}C$, 26$^{\circ}C$, 30$^{\circ}C$, there were significantly higher rates of body movement in the room temperature(30$^{\circ}C$). 3) Uncomfortable after sleep in thermal environment is mostly under high temperature(30$^{\circ}C$), and they are about fatigue due to not enough sleeping. 4) The degree of indoor thermal temperature with sufficient sleeping is in 22.8 ∼ 27.8$^{\circ}C$.
