ABSTRACT
Purpose@#The purpose of this study was to investigate the perception of ototoxicity related to chemotherapy (cisplatin) and management status among nurses and doctors. @*Methods@#The participating subjects were 247 nurses working in the oncology ward and the anti-cancer injection room and 40 internal medicine doctors in C University Hospital of D City. The data were collected from October to November 2019, using a self-report structured questionnaire and analyzed by the SPSS/WIN 24.0 program. @*Results@#As a result of this study, 51.4% of nurses answered that they had knowledge of ototoxicity, 33.5% provided prior information on ototoxicity, and 4.5% provided information on the hearing test before cisplatin administration. The group with knowledge of cisplatin-related ototoxicity provided more information on both ototoxicity (χ²=105.02, p<.001) and hearing test (χ²=5.27, p=.022) than the group without knowledge of ototoxicity. The provision of education, including the contents of ototoxicity, improved the nurses’ knowledge about cisplatin-related ototoxicity, and it was found that more information about hearing loss was provided. @*Conclusion@#It was confirmed that education on the symptoms of cisplatin-related ototoxicity was required and no ototoxicity management system was in place. Therefore, it is necessary to develop an ototoxicity management program at the hospital level, which will have an effect on improving nursing practice for cancer patients.
ABSTRACT
An experiment to search for light sterile neutrinos is conducted at a reactor with a thermal power of 2.8 GW located at the Hanbit nuclear power complex. The search is done with a detector consisting of a ton of Gd-loaded liquid scintillator in a tendon gallery approximately 24 m from the reactor core. The measured antineutrino event rate is 1976 per day with a signal to background ratio of about 22. The shape of the antineutrino energy spectrum obtained from the eight-month data-taking period is compared with a hypothesis of oscillations due to active-sterile antineutrino mixing. No strong evidence of 3+1 neutrino oscillation is found. An excess around the 5 MeV prompt energy range is observed as seen in existing longer-baseline experiments. The mixing parameter sin^{2}2θ_{14} is limited up to less than 0.1 for Δm_{41}^{2} ranging from 0.2 to 2.3 eV^{2} with a 90% confidence level.
