Abstract

|

Purpose: This study aimed to investigate research status by applying key word network analysis to Korean key words selected by the authors of Journal of Korean Ophthalmic Optics Society (KOOS) papers.
Methods: We selected Korean key words (980) that were marked by the author in the Korean abstract among papers published (4,640) in KOOS as subjects, and performed key word filtration. After analyzing frequency of appearance of these subjects and selecting top 10 key words for frequency of appearance, analysis of frequency of co-occurrence and centrality was performed for key words that appeared together in the papers in which they appeared.
Results: The top 10 key words for frequency of appearance were soft contact lens, refractive error, optician, myopia, contrast sensitivity, contact lens, visual acuity, binocular vision, and astigmatism. After conducting network analysis, the highest frequency of co-occurrence was ‘refractive error-myopia’ and it was followed by ‘myopiaastigmatism’, ‘myopia-hyperopia’, and ‘phoria-binocular vision’. Degree centrality and betweenness centrality were the highest in ‘soft contact lens’ and closeness centrality and eigenvector centrality were the highest in ‘refractive error’.
Conclusions: The research status of KOOS, focusing on author key words, confirmed that many studies related to ‘refractive error’, ‘visual function’, and ‘contact lens’ has been conducted. We expect to conduct research on a variety of other topics in the future.
