This case involves a renowned hospital whose infrastructure has expanded over the years to meet growing demands, including outpatient and medical services. The hospital's maintenance department oversees a wide range of responsibilities, including water, electricity, and gas systems. To align with the hospital's core philosophy, dedicated personnel are required to maintain these systems 24/7, 365 days a year. To address recent manpower shortages, the hospital has implemented the "GKB Ultra-Early Disaster Prevention and Active Notification System," leveraging advanced technology to support medical logistics, public convenience, and campus safety.
