This study analyzes research trends in mushrooms using social network analysis (SNA) and Word2Vec analysis based on 654 papers published in the journal of mushrooms. By tracking changes in research trends through centrality indices of key keywords and temporal keyword associations, it was found that in the early period (2011–2015), research primarily focused on optimizing growth conditions. During the mid-period (2016–2020), studies on strain characteristics and disease resistance became more prominent. In the recent period (2021–2024), research on molecular biology and functional components has expanded significantly, with molecular biology research, substrate and cultivation environment studies, and quality and functional food research emerging as new research areas. Meanwhile, research on Pleurotus ostreatus has been the most active, whereas studies on other mushroom species remain relatively limited, indicating the need for a broader scope in future research. This study provides an in-depth review of the research trends and transformations in the journal of mushrooms, contributing to the discussion on its balanced development and future research directions.

This paper aims to develop the AE non-destructive testing equipment and signal analysis method for external tendon of PSC (Pre-Stressed Concrete) bridge. The AE NDT equipment, which has developed in this research, is composed of AE sensor, signal receiver, hitting device, driving part and main frame. Defective and non-defective specimens, designed to emulate signal characteristics for external duct with void(25%, 50% and 100%) or not, were constructed and tested to verify the effectiveness of AE NDT equipment. Test results and AE parameters comparisons between defective and non-defective specimens are presented.
