Purpose: The purposes of this review were to address misconceptions of childhood fever and fever management practice among parents and health care providers, and to identify the scientific evidences against such misconceptions and practices. Methods: Journal databases and clinical guidelines from 2000 to 2015 were searched. The search terms were fever, fever management, misconception, myth, fiction, fact, fever phobia, child, antipyretics, tepid bath, alternating use/combined use of antipyretics, and physical cooling method. Results: There are significant gaps between current concepts and practices, and the scientific evidence. Misconceptions and unrealistic concerns about childhood fever still exist among parents and even health care providers, worldwide. The evidences suggest that antipyretics should be given carefully with the aim of relieving discomfort or pain rather than decreasing the temperature itself. Alternating use of antipyretics should be discouraged due to the risk of confusion and error. Antipyretics do not prevent febrile convulsions. Moreover, the scientific evidence does not support tepid sponge massage. Conclusion: Evidence-based childhood fever management interventions should be targeted toward parents and health care providers. By adopting an evidence-based approach to nursing interventions, pediatric nurses can ensure children receive appropriate and safe fever management.

In this study, we used a chemiluminescence reaction to investigate the removal effect of pet soil, such as dog blood, urine and feces. The soiled fabrics were washed with a standard laundry course of 30℃ and a washing time of 30 min and a pet care laundry course of 40-60℃ and a washing time of 100 min. The detergency was evaluated by the surface reflectance and chemiluminescence reaction (bloodstain detection by luminol test and urine-stain and feces-stain detection by UV blacklight test) before and after washing. The surface reflectance results did not show any difference in detergency for both courses, whereas the chemiluminescence reaction did. The detergency of the pet care course compared to the standard course was 101% according to the surface reflectance and 120% according to the chemiluminescence reaction. Therefore, residual stains not detected by surface reflectance can be evaluated through chemiluminescence reaction, and it was confirmed that pet stains can be managed more hygienically by washing for a long time at a high temperature.

In this study, we formulated oil-in-water emulsion composition for skin care products containing jadeite powder which is well known as far-infrared radiating material. Jadeite powder could sustain stable dispersion in aqueous solvents over a month and this helped mixing it high content in oil-in-water emulsion formulation. To identify the effect of jadeite as a far-infrared radiator materials relating to the skin surface temperature change, we applied emulsion formulation containing 2 weight percent jadeite powder onto facial skin surface and blank formulation together and analyzed surface temperature with thermo-vision. Our results showed that the temperature difference between jadeite powder formulation applied region and blank formulation reached to 1.5 ~ 2.0 degree Celsius. We also performed same test with nephrite powder and titanium dioxide powder but only jadeite powder containing formulation showed significant skin temperature change. To elucidate main cause of heat energy transfer, we tested heat radiation, energy dispersive spectrometer analysis and measured far infrared radiance emissivity, diffuse reflectance spectra and water evaporation rate. We found out jadeite powder could retard water evaporation effectively from the skin surface and resist temperature drop down. This is because of the innate chemical composition and surface structure of jadeite, which can bind with water molecules to form hydrogen bonds. It is concluded that we can develop novel skin care products for moisturizing and thermos with jadeite powder.

Purpose: Maintaining body temperature is a key vital function of human beings, but little is known about how body temperature of highrisk infants is sustained during early life after birth. The aim of this study was to describe hypothermia in high-risk infants during their first week of life and examine demographic, environmental, and clinical attributors of hypothermia. Methods: A retrospective longitudinal study was done from January 1, 2013 to December 31, 2015. Medical records of 570 high-risk infants hospitalized at Neonatal Intensive Care Units (NICU) of a university affiliated hospital were examined. Body temperature and related factors were assessed for seven days after birth. Results: A total of 336 events of hypothermia (212 mild and 124 moderate) occurred in 280 neonates (49.1%) and most events (84.5%) occurred within 24 hours after birth. Logistic regression analysis revealed that phototherapy (aOR=0.28, 95% CI=0.10-0.78), Apgar score at 5 minute (aOR=2.20, 95% CI=1.17-4.12), and intra-uterine growth retardation or small for gestational age (aOR=3.58, 95% CI=1.69-7.58) were statistically significant contributors to hypothermia. Conclusion: Findings indicate that high-risk infants are at risk for hypothermia even when in the NICU. More advanced nursing interventions are necessary to prevent hypothermia of high-risk infants.

Purpose: The study was conducted to identify factors affecting the intraoperative core body temperature (CBT) of surgical patients under general anesthesia. Methods: This study was performed through a prospective descriptive research design. The sample consisted of 138 patients who had undergone elective laparotomy surgery. Age, weight, height, the basal preoperative CBT, blood pressure, and heart rate were collected. CBT was again measured at induction of anesthesia, 1 hour, 2 hours, and 3 hours following induction of general anesthesia. Results: Factors affecting intraoperative hypothermia < $36^{\circ}C$ at 1 hour following induction, were CBT at induction and total body fat (TBF) ($R^2=.569$, p<.001); at 2 hours after induction, CBT at induction and TBF ($R^2=.507$, p<.001); at 3 hours after induction, CBT at induction (${\beta}=0.34$), TBF, age and the ambient temperature in the operating room ($R^2=.449$, p<.001). Conclusion: CBT at induction and TBF appear to be factors affecting intraoperative CBT within 2 hours after induction of anesthesia; CBT at induction, TBF, advanced age and the ambient temperature after 3 hours following induction. We recommend keeping surgical patients warm before induction of anesthesia and providing intraoperative warming for surgical patients of advanced age with low TBF and when the duration of general anesthesia will last more than 3 hours.

The study in the fild of medical instrument has been out of the interest by any of the life scientist in Korea. Especially, the recent developments in the medical electromics are remarkable one. Authors planned this study to ascertain the possibility of setting up the thermister thermometer with available accessories of demestic prouducts including some specific foreign assembly parts. By proper use of the thermister as one of the wheatstone bridge, we could detect tile resistance variations due to the environmental temperature variace. The intensive care for the bridge circuit and compensation scheme was required. The calibration procedure adopted here makes it possible to read the current as the temperature. The temperature range was determined by the examination and construction of the graph of the resistance-temperature variation. The determination of electric current, available ambient-temperature, the reduction of excessive current and self-heating of the thermister were made. Renovation in response-velocity was under taken too. This electronic thermometer was designed and assembled by the circuitry developed in accordance with the maximum availability of domestic products with some foreign-made parts. The result of our experiment showed very stable function and proved to be the most promissing item in the actual application as long as the thermistor thermister is concerned.

This study was to identify the nursing intervention method in finding out the incidence, risk factor, prevention and treatment of bed sore cilents who received regional home care nursing services. The eleven home care nurse practitioners took the survey on 97 patients who received home care nursing service from Seoul City Nurses Association for one month from September 26 to October 26 1996. A modified version of Braden's bed sore assessment tool for bed sore risks and a tool for assessment of bed sore stage and measurement bed sore sizes by Bergstrom, Braden, Laguzza and Holman(1987) were as research tools for this study and a questionnare with 40 questions and 12 items on nursing activities was used to find out the prevention and treatment of bed sores. Also, two open ended questions were used on current approaches and efforts of the treatment being applied to clients. The finding of the study were summarized as following : 1. The rate of bed sore occurrence was 47.4% 2. The areas of bed sore occurrence were hip(28.9%), sacrum(18.6%), great trochanter(14.4%) and the average number of sore spots were 2.26 3. Two groups-one with bed sores and the other without-were studied to determine prediction factors for bed sore risks. Sensory function, humidity, level of activity, mobility, nutrition, skin friction and chapping and body temperature turned out to be statistically significant factors for bed sores. Also the age of clients turned out to be a individual characteristic variable significantly affecting the rate of bed sore occurrences. 4. The education for clients and family on systematic skin assessment and bed sores and practice of active/passive R.O.M. are mainly used as nursing activities for bed sore care. 5. The treatment method varied by stages of bed sores. Sometimes folk remedies like applying the powders of dried elm tree roots to sores were used. Good nutrition, frequent position change and skin care turned to be the most effective means to fast recovery of sores.

With ubiquitous computing aid, it can improve human being's life quality if all people have more convenient medical service under pervasive computing environment. In this paper, for a pervasive health care application for diabetes patient, we've implemented a health care system, which is composed of three parts. Various sensors monitor both outer and inner environment of human such as temperature, blood pressure, pulse, and glycemic index, etc. These sensors form zigbee-based sensor network. And as a backend, medical information server accumulates sensing data and performs back-end processing. To simply transfer these sensing values to a medical team may be a low level's medical service. So, we've designed a model with context awareness for more improved medical service which is based on ART(adaptive resonance theory) neural network. Our experiments show that a proposed healthcare system can provide improved medical service because it can recognize current context of patient more concretely.

The solar X-ray telescopes, the Yohkoh SXT and the Hinode XRT, have observed for a couple of decades a variety of coronal structures in the range of wide field-of-view (FOV) covering the full solar disk. It has been emphasized that the optical structure of solar telescopes should be designed with care for improving the uniformity over the full FOV. The vignetting effect is one of the important optical characteristics for describing the performance of a telescope, which reflects the ability of collecting the incoming light at different locations and different photon energies. The correction of this vignetting effect would be an important calibration step that should be performed in advance, especially when the observed images are to be used for photometric purposes. Since the vignetting effect of solar X-ray telescopes shows wavelength dependence, a special care should be taken when, for example, performing the temperature analyses with thin and thick filters for flaring activities observed at the periphery of the full FOV. The results of analysis of pre-launch calibration data for the evaluation of vignetting effect will be introduced in detail.
