This study addresses the critical public health issue of fecal coliform contamination in the four major rivers in South Korea (Han, Nakdong, Geum, and Yeongsan rivers) by applying advanced machine learning (ML) algorithms combined with Explainable Artificial Intelligence to enhance both prediction accuracy and interpretability. Both traditional and machine learning models often face challenges in accurately estimating fecal coliform levels due to the complexity of environmental variables and data limitations. To address this limitation, we employed two tree-based models (i.

Eutrophication is a major cause of water quality degradation in South Korea, owing to severe algal blooms. To manage eutrophication, the South Korean government provided the Trophic State Index (TSIko), which was revised according to Carlson's TSI. The TSIko levels were simulated using mechanistic water quality modeling.

Background: Preoperative carbohydrate treatment attenuates insulin resistance and improves metabolism to an anabolic state. Despite these benefits, impaired glycemic control and aspiration risk related to gastroparesis represent concerns for patients with diabetes undergoing surgery. This randomized controlled trial investigated the effects of oral carbohydrate therapy on perioperative glucose variability, metabolic responses, and gastric volume in diabetic patients undergoing elective total hip or knee arthroplasty.

While both baseline regional cerebral oxygen saturation (rSO) and intraoperative rSO decreases have prognostic importance in cardiac surgery, evidence is limited in patients who received interventions to correct rSO decreases. The primary aim was to examine the association between rSO values (both baseline rSO and intraoperative decrease in rSO) with the composite of morbidity endpoints. We retrospectively analyzed 356 cardiac surgical patients having continuously recorded data of intraoperative rSO values.

Growth hormone (GH) secretion is regulated by various hormones or neurotransmitters, including gamma-aminobutyric acid. The aim of this study was to determine the propofol requirement in patients with GH-secreting pituitary tumors undergoing transsphenoidal surgery. General anesthesia was induced in 60 patients with GH-secreting tumors (GH group, = 30) or nonfunctioning pituitary tumors (NF group, = 30) using an effect-site target-controlled intravenous propofol infusion.
