Periodic Auditor Designation, Audit Fees and Audit Effort: Evidence from the Korean Mandatory Designation Regime

From fiscal year 2020, Korea has required a listed company that has kept the same auditor for six consecutive years to accept an auditor chosen by the securities regulator and keep it for three years. This study estimates what the rule costs and what it delivers. Using 17,890 fir...

Exercise-Induced Activation of IGF-1/mTOR Signaling and Hippocampal BDNF/PGC-1α Expression Reverses Age-Related Motor Decline

Purpose: Aging is associated with a progressive decline in skeletal muscle function and motor coordination, contributing to reduced mobility and quality of life. While exercise is a well-established intervention to counteract age-related deterioration, the underlying molecular me...

Surface Ligand‐Mediated Carrier Balance for Stable Inverted Red InP Quantum Dot Light‐Emitting Diodes

ABSTRACT Indium phosphide (InP)‐based quantum dots (QDs) are cadmium (Cd)‐free emitters for display applications, but their operational stability is limited by surface defects and imbalanced carrier injection. Here, we introduce a [2‐(9H‐carbazol‐9‐yl)ethyl]phosphonic acid (2PACz...

Career Sustainability in High‐Risk Performance Populations: The Mediating Role of Grit Between Growth Mindset and Career Decision Self‐Efficacy

ABSTRACT In precarious and high‐stakes vocational environments, fostering psychological sustainability is a critical challenge for employment counseling. This study investigates a modifiable psychological pathway—the mediating role of grit between growth mindset and career decisi...

Directionally Aligned, Defect-Suppressed Non-oxidatively Exfoliated Graphene Flakes for High EMI Shielding Performance

Abstract In this study, we report the development of high-performance electromagnetic interference (EMI) shielding composites incorporating directionally aligned non-oxidatively exfoliated graphene flakes (NOGF) within a polydimethylsiloxane (PDMS) matrix. The NOGF was synthesize...

An Empirical Study of Factors Associated with Construction Robot Adoption Prospects Among Personnel in Small-Sized Construction Firms

Construction robots are attracting increasing attention as a response to labor shortages, workforce aging, and stagnant productivity in the construction industry. However, small-sized construction firms may face adoption difficulties because of limited investment capacity, shorta...

Vertical sensor design with amplified capacitive response for improved humidity sensing

We propose a novel vertical capacitive humidity sensor capable of transducing the resistance variation of a humidity-sensitive material into a corresponding capacitance change. The proposed hydroxyethyl cellulose-based vertical structure expands the distribution of electric flux...

Low-Energy Organic Ferroelectric Synaptic Transistors Enabled by Interfacially Engineered Gate Insulators

Abstract Solution-processed organic ferroelectric transistors are promising synaptic components for portable and wearable neuromorphic systems. However, compared with oxide-based platforms, these transistors generally require relatively thick ferroelectric gate layers and, conseq...

Military terrain-conditioned decoy-aware mask refinement network for open-vocabulary camouflaged object segmentation

Military camouflage creates two coupled errors for open-vocabulary segmentation: uncertain object boundaries and terrain-induced class confusion. We propose the Military Terrain-Conditioned Decoy-Aware Mask Refinement Network (MT-DAMRNet), a terrain-decoy refinement layer on top...

Association between stride length variability and osteosarcopenia in community-dwelling older women: a cross-sectional study

Abstract Background Osteosarcopenia, the coexistence of sarcopenia and low bone mass, raises the risk of falls, fractures, and functional decline, yet its diagnosis depends on dual-energy X-ray absorptiometry (DXA) and muscle function testing, which are difficult to apply routine...
