Purpose: In this study, factors influencing the performance of person-centered care among nurses in designated COVID-19 hospitals were examined. Methods: A total of 182 nurses providing care to COVID-19 patients at six public hospitals in Gyeonggi-do the designated hospital for infectious diseases participated in the study. Data were collected from February to March 2021 using a 152-question structured questionnaire, and analyzed using SPSS/WINdows software, version 25.0 by frequency and percentage, mean and standard deviation, independent t-test, one-way ANOVA, Pearson’s correlation coefficients, and multiple regression. Results: The factors influencing the respondents’ performance of person-centered care were organizational culture for infection control (β=.35, p<.001), empathic ability (β=.16, p=.027), and the charge nurse position (β=.14, p=.035);these explained 20.8% of their person-centered care. Conclusion: It is necessary to consider strategies to improve the organizational culture for infection control and empathic ability to promote the performance of person-centered care among nurses at designated COVID-19 hospitals. It is also necessary to design a program that can facilitate the implementation of person-centered care by nurses who hold positions junior to that of the charge nurse at designated COVID-19 hospitals. © 2022 Korean Society of Adult Nursing

Recently, the bio-healthcare market is enlarging worldwide due to various reasons such as the COVID-19 pandemic. Among them, biometric measurement and analysis technology are expected to bring about future technological innovation and socio-economic ripple effect. Existing systems require a large-capacity battery to drive signal processing, wireless transmission part, and an operating system in the process. However, due to the limitation of the battery capacity, it causes a spatio-temporal limitation on the use of the device. This limitation can act as a cause for the disconnection of data required for the user's health care monitoring, so it is one of the major obstacles of the health care device. In this study, we report the concept of a standalone healthcare monitoring module, which is based on both triboelectric effects and electromagnetic effects, by converting biomechanical energy into suitable electric energy. The proposed system can be operated independently without an external power source. In particular, the wireless foot pressure measurement monitoring system, which is rationally designed triboelectric sensor (TES), can recognize the user's walking habits through foot pressure measurement. By applying the triboelectric effects to the contact-separation behavior that occurs during walking, an effective foot pressure sensor was made, the performance of the sensor was verified through an electrical output signal according to the pressure, and its dynamic behavior is measured through a signal processing circuit using a capacitor. In addition, the biomechanical energy dissipated during walking is harvested as electrical energy by using the electromagnetic induction effect to be used as a power source for wireless transmission and signal processing. Therefore, the proposed system has a great potential to reduce the inconvenience of charging caused by limited battery capacity and to overcome the problem of data disconnection.
