The purpose of this study is to analyze research trends of Korean language education for occupational purpose. For this research, the Research Information Sharing Service(RISS) collected paper related to Korean language education for occupational purpose, and collected a total 261 papers, including 209 academic papers and 52 academic journals. Based on the collected papers, the number of papers was analyzed by paper count course(year, time), network analysis(word cloud, frequency, centrality, word pairs, visualization), and topic modeling, respectively. Based on this, we identified the discussion points and future research trends of occupational Korean language education research. Research began in 2001 and has been focused on 'textbooks', 'development', 'plan' and 'analysis'. Looking at the word pairs, "development-textbooks" also appeared the most. According to the analysis of the topic modeling, the development and analysis of textbooks(60.5%), curriculum and measures(30.7%), and education status(8.8%) showed a ratio of about 6:3:1. As a result of the above analysis of research trends, I think that first, learners need necessary textbooks, second, development of textbooks for various occupational groups, and finally, the goal of improving learners' Korean language skills.(Inha University)
