Soft coral-associated actinomycetes have been increasingly recognized as promising sources of marine natural products. However, a comprehensive synthesis of their taxonomic diversity, cultivation features, and metabolic potential is still lacking. In this review, studies on coral-associated actinomycetes reported between 2007 and 2025 are comprehensively examined. The biological and ecological background of corals is outlined,...

This study introduces a spatial encoder network designed to estimate sand size distribution from optical images of sediments. The model achieves sufficient network capacity by stacking two-dimensional convolution-based encoder blocks to learn the spatial features that relate sediment images to grain size distribution. Additionally, to improve robustness and reliability, data augmentation techniques, including horizontal and ve...

Actinomycetes are key producers of bioactive secondary metabolites. In this study, sediment samples were collected using a grab sampler from the coast of Ulleung Island and inoculated on various agar media by stamping to isolate Actinomycetes. As a result, 69 Actinomycete strains were isolated and laboratory-cultured from the sediment samples. The isolates were assigned to the genera Streptomyces (44 strains), Nocardia (6 stra...

Beach profiles are constantly changing due to external ocean forces. Estimating these changes is crucial to understanding and addressing coastal erosion issues, such as shoreline advance and retreat. To estimate beach profile changes, obtaining long-term, high-resolution spatiotemporal beach profile data is essential. However, due to the limited availability of beach profile survey data both on land and underwater along the co...
