Effects of Perch on Productivity, Welfare, and Physiological Indicators of Broiler Chickens Reared in Animal Welfare-Certificated Farms.

This study explored the impact of perches on the productivity and welfare of broilers raised on two animal welfare-certified farms (designated as Farm A and B) in South Korea. Broiler houses in each farm were provided with or without wooden square-shaped perches (2 × 2 cm) at a rate of 2 m per 1000 birds. The study aimed to assess whether perches could influence productivity measures, such as weight and uniformity, and animal welfare indicators, including corticosterone levels and physical health markers.

Isolation and Characterization of Bioactive Compounds from sp. CMS18 and Their Antifungal Properties.

In this study, metagenomic analysis was employed to investigate the bacterial communities in the Muan tidal mudflat of the Republic of Korea. We used metagenomic analysis to identify the microbial community in tidal soil dominated by Proteobacteria. From this environment, the bacterial strain, sp.

Clinical Impact of TP53 Mutations in Patients with Head and Neck Cancer Who Were Treated with Targeted Therapies or Immunotherapy.

Purpose: TP53 mutations are common in head and neck squamous cell carcinoma (HNSCC). We evaluated their clinical impact in patients treated with targeted agents or immunotherapy in the KCSG HN15-16 TRIUMPH trial.

Materials And Methods: We analyzed clinical characteristics and outcomes of patients with TP53 mutations in the TRIUMPH trial, a multicenter, biomarker-driven umbrella trial in Korea.

Assessing the Overall Technical Efficiency, Pure Technical Efficiency, and Scale Efficiency of United States Department of Defense Hospitals.

Introduction: This study aims to evaluate US Department of Defense hospital efficiency.

Methods: Drawing on the American Hospital Association's annual survey data, the study employs data envelopment analysis, slack analysis, and the Malmquist Productivity Index to identify the differences in hospital efficiency between Air Force, Army, and Navy hospitals as well as the trends of their efficiency from 2010 to 2021.

Results: US Department of Defense hospitals operated inefficiently from 2010 to 2021, although the average technical efficiency of all DOD hospitals increased slightly during this period.
