Formalin‐inactivated vaccines are widely employed as a primary preventive strategy against red sea bream iridoviral disease (RSIVD), which poses a substantial economic threat to the aquaculture of rock bream ( Oplegnathus fasciatus ). However, conventional quantitative PCR (qPCR) cannot differentiate infectious virions from noninfectious vaccine residues or viral debris, limiting accurate assessment of vaccine efficacy. Theref...

This study proposes a stability-aware load-shaping energy management system (EMS) for a hybrid electric shipboard power system. The proposed EMS uses the energy storage system (ESS) as a dynamic load-shaping buffer to reduce active diesel-generator (DG) low-load exposure and electrical power fluctuations. A supervisory reference-generation procedure integrating low-pass filtering, ESS state-of-charge (SOC) compensation, DG ram...

Safe navigation in coastal waters remains a persistent challenge for conventional grid-based path planning methods, which prioritize shortest-distance optimization while neglecting spatial risk distribution and kinematic trackability. This study proposes a local path planning framework that integrates an integral image-based risk field with kinematic constraints for small vessel navigation in high-resolution coastal environmen...

Introduction High water temperature (HWT) marine-heatwave events along the southern coast of South Korea cause repeated mass mortalities in cage aquaculture of olive flounder (Paralichthys olivaceus), rock bream (Oplegnathus fasciatus), red sea bream (Pagrus major) and Korean rockfish (Sebastes schlegelii). Existing operational forecasts rely on coarse numerical ocean models that lack the temporal granularity and site specific...
