Purpose in Life Among Older Adults: A Machine Learning Analysis of Potential Predictors

A sense of purpose is a central component of mental well-being in older adulthood. Although many predictors of purpose have been identified, most studies have considered a limited set, leaving their relative importance unclear. The present study addressed this gap by examining a...

When market orientation backfires: the asymmetric effects of proactive and responsive orientation on marketing capabilities and performance

Purpose This study aims to examine how proactive and responsive market orientations (RMOs) are associated with the development of digital and traditional marketing capabilities (TMCs) in business-to-business (B2B) small and medium-sized enterprises (SMEs), and how those capabilit...

Impact of Polyimide Semi-Interpenetrating Polymer Networks on the Physicochemical Properties of Vulcanized Acrylonitrile–Butadiene Rubber

This work demonstrates the physicochemical property changes of composite thermoset elastomers prepared by incorporating mechanically and thermally stable polyimide (PI) into vulcanized acrylonitrile butadiene rubber (NBR) through a semi-interpenetrating polymer network (semi-IPN)...

Discordant Antitumor Efficacy with Compromised Survival in High-Risk Unresectable Hepatocellular Carcinoma

Background/Objectives: Real-world data in high-risk patients remain limited; this study evaluated survival, safety, and prognostic factors in this patient group. Methods: This multicenter study retrospectively reviewed 783 patients who received Ate/Bev from 2022–2024 across South...

Age- and sex-adjusted genomic differences between Korean and Beat AML cohorts

Genomic profiling plays a central role in risk stratification and therapeutic decision-making in acute myeloid leukemia (AML), yet the clinical implications of population-specific genomic architectures remain incompletely defined. We conducted a prospective, multicenter study of...

Efficacy of Polyhexamethylene Biguanide Antibacterial Gel Coating of Orthopedic Implants in Infection Control and Immune Modulation

ABSTRACT With the growth of the older adult population and the increasing incidence of traumatic injuries, the use of orthopedic devices has risen significantly. However, in addition to material‐related limitations, one of the most serious challenges associated with these devices...

Mechanical performance of polyvinyl alcohol macrofiber‐reinforced very‐early‐strength latex‐modified concrete for early‐opening pavement repair

Abstract Very‐early‐strength latex‐modified concrete (VES‐LMC) is widely used for emergency pavement repairs requiring rapid opening to traffic; however, improving mechanical performance while maintaining early‐age strength remains a challenge. This study evaluates the effectiven...

3D‐Printed Mold‐Cast MWCNT/PDMS Flexible Heatsinks for Thermal Management

ABSTRACT The innovative concept of converting solid thermal conductors into flexible components is emerging as a compelling development in materials science and electronics. Flexible heatsink designs offer dynamic and adaptable solutions in the field of thermal management. This s...

Defining the problem of pandemic resource allocation: perspectives from healthcare providers and civil society advocates in South Korea

Abstract Background The COVID-19 pandemic raised ethical questions about how scarce medical resources should be defined and allocated. Existing debates have largely focused on triage criteria and distributive principles, with less attention to how different social and institution...

Current concepts in distal clavicle fractures: an evidence-based update

Background: Clavicle fractures are common orthopaedic injuries that frequently occur during sports and recreational activity.Purpose: To (1) determine the incidence rate of sports-related clavicle fractures among patients evaluated in emergency departments in the United States ov...

Shockable rhythm as an independent prognostic factor in patients with non-ST elevation undergoing percutaneous coronary intervention after out-of-hospital cardiac arrest: a registry-based cohort study

BACKGROUND: Although the timing and indications for coronary angiography (CAG) after out-of-hospital cardiac arrest (OHCA) have been widely studied, the characteristics associated with favorable outcomes in patients with non-ST-elevation (non-STE) undergoing percutaneous coronary...

Aging Biology of Bone-to-Tendon Healing and the Epigenetic Clock: A Biological-Age Readout of Rotator Cuff Healing Capacity

The “unexplained failure” of rotator cuff repair is multifactorial, but its structural endpoint is anatomically consistent, i.e., the failure of the tendon-to-bone interface (enthesis) to heal. The native enthesis is a four-zone fibrocartilaginous gradient that does not regenerat...

Digital Connectivity and Human Capital Development: Understanding the Distraction Paradox in Higher Education Using Structural Equation Modelling

Abstract Digital technologies have rapidly transformed teaching and learning in higher education in recent years, reshaping the learning environment alongside factors that influence technology acceptance and users' digital competence. Grounded in the Technology Acceptance Model (...

Restricted Loss of Life Expectancy in Patients With Acute Myocardial Infarction: A Nationwide KAMIR Registry Study

Background The mortality risk of acute myocardial infarction declines rapidly after the initial period, yet the quantitative measures of residual risk in the follow‐up period remain limited. We aimed to assess restricted loss of life expectancy (LOLE) in patients with acute myoca...

Withdrawal period estimation of a long-acting intramuscular amoxicillin trihydrate–florfenicol combination in olive flounder
