Effectiveness of donning and doffing personal protective equipment education using video debriefing among Korean undergraduate nursing students.

Background: The use of appropriate personal protective equipment (PPE) in healthcare settings is a very important factor of infection control activities to prevent transmission of infection. In this study, we aimed to develop a non-face-to-face method that can reduce transmission of infection and an educational method that allows self-learning and self-training, and verify the effectiveness of a donning and doffing PPE education using video debriefing on third-year nursing students in clinical train.

Methods: The researcher assigned groups through random sampling using a random number table from the list of research subjects who agreed to participate.

Etch characteristics of maskless oxide/nitride/oxide/nitride (ONON) stacked structure using CHF-based gas.

Oxide/Nitride/Oxide/Nitride (ONON; SiO/SiN/SiO/SiN) stacked structure is widely used in the 3D vertical structure of semiconductor cells. Previously, to form a 3D cells, photoresist (PR) was patterned and repeatedly trimmed on the top of ONON after the etching of one ON layer. Due to the time-consuming process of etching layer-by-layer of ON layer, two-step etch processing using CF-based or CF-based gases composed of maskless ONON stack feature etching and followed one ON layer-by layer etching by PR trimming in the ONON stack feature are employed these days.

Effect of Cl Radical on Dry Development of Spin-Coated Metal Oxide Resist.

In this study, the effects of Cl radicals on dry development of spin-coated metal oxide resist (MOR) and changes in its surface binding states were investigated to verify the mechanism of dry development. Dry development characteristics of tin hydroxide (Tin OH), which is one of the MOR candidates for next generation lithography, were investigated as functions of process time and temperature using a Cl radicals source. Non-UV-exposed Tin OH film showed a linear etch rate (1.

Risk of COVID-19 transmission on long-haul flights: During the COVID-19 pandemic.

This study aimed to determine the possibility of COVID-19 transmission through in-flight contact during flights for many patients with confirmed COVID-19 during the COVID-19 pandemic and explore infection prevention and control (IPC) methods for overseas infectious diseases. A retrospective cohort study was conducted on flight with a large number of confirmed case among. Delhi- Incheon flights in 2020.

Biocompatible Co-organic Composite Thin Film Deposited by VHF Plasma-Enhanced Atomic Layer Deposition at a Low Temperature.

Although metal-organic thin films are required for many biorelated applications, traditional deposition methods have proven challenging in preparing these composite materials. Here, a Co-organic composite thin film was prepared by plasma-enhanced atomic layer deposition (PEALD) with cobaltocene (Co(Cp)) on polydimethylsiloxane (PDMS), using two very high frequency (VHF) NH plasmas (60 and 100 MHz), for use as a tissue culture scaffold. VHF PEALD was employed to reduce the temperature and control the thickness and composition.
