Currently, most island regions have independent microgrids composed of distributed power sources, including renewable energy, and there are many restrictions on implementing power generation control individually for these independent microgrids. Therefore, for more efficient power generation control and operation, clustering between island regions with similar load patterns is necessary. In this paper, the load pattern was analyzed for the Korea Electric Power Corporation management island regions, and the clustering method used in the analysis process was explained in detail, and the reliability of clustering was improved by verifying whether the clustering results were valid. In addition, through the results of each clustering, the relationship between new and renewable energy, an independent microgrid, and the island region corresponding to each cluster, is analyzed to propose a power generation control and operation method for each cluster.

Sarcopenia, the age-related muscle atrophy, is a serious concern as it is associated with frailty, reduced physical functions, and increased mortality risk. Protein supplementation is essential for preserving muscle mass, and horse meat can be an excellent source of proteins. Since sarcopenia occurs under conditions of oxidative stress, this study aimed to investigate the potential anti-muscle atrophy effect of horse meat hydrolysate using C2C12 cells. A horse meat hydrolysate less than 3 kDa (A4<3kDa) significantly increased the viability of C2C12 myoblasts against H2O2-induced cytotoxicity. Exposure of C2C12 myoblasts to lipopolysaccharide led to an elevation of cellular reactive oxygen species levels and mRNA expression of proinflammatory cytokines, including tumor necrosis factor-α and interleukin 6, and these effects were attenuated by A4<3kDa treatment. Additionally, A4<3kDa activated protein synthesis-related proteins through the protein kinase B/mechanistic target of rapamycin pathway, while decreasing the expression of activity and degradation-related proteins, such as Forkhead box O3, muscle RING finger protein-1, and Atrogin-1 in dexamethasone-treated C2C12 myotubes. Therefore, the natural material A4<3kDa has the potential of protecting against muscle atrophy, while further in vivo study is needed.
