Pt-W alloy absorbers for high-NA EUV lithography: tunable optical and etching performance.

Extreme ultraviolet lithography is used to mass-produce nanoscale integrated circuits, and high-numerical-aperture systems for 3 nm technology nodes are currently being developed. However, conventional tantalum-based EUV masks face limitations in terms of resolving fine patterns. This study introduces platinum-tungsten alloys as alternative absorber materials that are advantageous from both imaging performance and manufacturability perspectives.

Cell-Division-Independent Rapid Expression of DNA Delivered with α-Synuclein-Gold Nanoparticle Conjugates.

Gene delivery is a primary technology employed in diverse areas of biomedical science, from gene therapy to gene editing, cancer treatment, and stem cell research. Here, we introduce a gene delivery system utilizing an intrinsically disordered protein of α-synuclein (αS) demonstrated to interact with lipid membranes by transforming its original random structure to an α-helix. Since the helix bundle formation is a signature of cell-penetrating peptides for membrane translocation, a multitude of αS(Y136C)s replacing tyrosine at the C-terminus with cysteine were covalently attached onto gold nanoparticles (AuNPs) in a specific orientation with the helix-forming basic N-termini exposed outward.

A novel machine learning model for screening the risk of obstructive sleep apnea using craniofacial photography with questionnaires.

Factors influencing the learning transfer of nursing students in a non-face-to-face educational environment during the COVID-19 pandemic in Korea: a cross-sectional study using structural equation modeling.

Purpose: The aim of this study was to identify factors influencing the learning transfer of nursing students in a non-face-to-face educational environment through structural equation modeling and suggest ways to improve the transfer of learning.

Methods: In this cross-sectional study, data were collected via online surveys from February 9 to March 1, 2022, from 218 nursing students in Korea. Learning transfer, learning immersion, learning satisfaction, learning efficacy, self-directed learning ability and information technology utilization ability were analyzed using IBM SPSS for Windows ver.

Hyperspectral reflectance imaging for nondestructive evaluation of root rot in Korean ginseng ( Meyer).

Root rot of caused by , a soil-borne fungus is typically diagnosed by frequently checking the ginseng plants or by evaluating soil pathogens in a farm, which is a time- and cost-intensive process. Because this disease causes huge economic losses to ginseng farmers, it is important to develop reliable and non-destructive techniques for early disease detection. In this study, we developed a non-destructive method for the early detection of root rot.

Intra-person multi-task learning method for chronic-disease prediction.

In the medical field, various clinical information has been accumulated to help clinicians provide personalized medicine and make better diagnoses. As chronic diseases share similar characteristics, it is possible to predict multiple chronic diseases using the accumulated data of each patient. Thus, we propose an intra-person multi-task learning framework that jointly predicts the status of correlated chronic diseases and improves the model performance.

Positive Effects on Emotional Stress and Sleep Quality of Forest Healing Program for Exhausted Medical Workers during the COVID-19 Outbreak.

This study targeted medical workers, who are currently being subjected to an excessive workload and emotional stress during the COVID-19 outbreak. Various treatment programs, such as a relaxation program to relieve stress, a walk in the forest, and woodworking were provided to the participants as forest healing therapies. We enrolled 13 medical workers (11 females, 2 males).
