Purpose This study aims to provide information on how to monitor the temperature setting of a heating device in order to implement a heating unit successfully in the smart clothing by observing voluntary heating behavior of wearers.Design/methodology/approach Subjects wearing base layers and additional clothing were asked to turn on and off the switch when wanted in the cold environmental chamber. Tolerable range of skin temperature (TST) depending on the location of body was obtained by observing the temperature at the time when the heating device was turned on and off during a rest–running–rest protocol.Findings The TST was 32.8–49.4 °C and decreased to 31.3–37.6 °C around abdomen and back waist, respectively. Changes in the wearers' voluntary control behavior were observed depending on the individual's level of cold-sensitivity and activity level of rest and running. TST was 35.8–49.4 °C (Rest 1: rest before exercise), 40.0–42.0 °C (Running) and 35.3–43.2 °C (Rest 2: rest after exercise) for cold-sensitive group, whereas it was 32.8–36.2 °C (Running) and 34.4–45.7 °C (Rest 2: rest after exercise) for cold-insensitive group.Originality/value In this study, results with detailed body locations and wearer's thermal sensitivity provide practical references for the implementation of a heating device to the comfortable multilayered smart clothing.
The purpose of this study was to determine whether repeated oral cryotherapy was effective in reducing nausea, vomiting, oral mucositis, and oral pain in patients with breast cancer receiving chemotherapy during the 1 st , 2 nd , and 3 rd rounds of chemotherapy for the first time. Methods: A nonequivalent control group non-synchronized design was used. The experimental group (n=21) received oral cryotherapy that applied a 2×2×2 cm ice cube in the mouth for 30 minutes at each chemotherapy. Both experimental group and control group (n=20) received oral care educations. Nausea, vomiting, oral mucositis and oral pain were measured on 5 days, 14 days, and 21 days after each chemotherapy. Data were collected from July 2019 to April 2020 at a university hospital in Korea, and analyzed using the SPSS WIN 25.0 software package. Results: There was a significant difference between the experimental and control groups in the nausea•vomiting score, oral mucositis grade, and oral pain score. Oral cryotherapy was confirmed to be effective in delaying nausea and vomiting. It has been shown that stomatitis and oral pain are related. Conclusion: For breast cancer patients receiving chemotherapy, it is recommended to apply oral cryotherapy as a nursing intervention to reduce nausea, vomiting, oral mucositis, and oral pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
