Abstract

Objective : The purpose of this study was to quantitatively analyze the quantitative changes in, and the status of, overseas occupational therapy using text mining. Methods : Using PubMed, research papers on Elderly, Health and Occupational therapy published between 2009 and 2019 were selected for analysis, Abstracts of the selected papers were analyzed. The number of annual papers, the key words, the key words by year, and the relationship between the words were analyzed. Results : The number of papers published from 2009 to 2019 was 9,941, there was a gradual increase from 2009 to the highest in 2017 or 2018, followed by a decreasing trend in 2019. Within the last five years, the most frequent words were Care, Group, Intervention, Pain, Treatment, and Work. There was a strong relationship between the words based on the average frequency over the last 11 years, function, health, event, and partition. Conclusion : This study is meaningful because it applied a new research method called text mining to the empirical and systematic analysis of trends in occupational therapy and presented macroscopic and comprehensive results. The findings are expected to help establish new research directions at clinical and research sites for occupational therapy related to older adults.

목적 : 본 연구는 텍스트마이닝을 활용하여 국외 노인 작업치료의 양적 변화와 현황 파악을 정량적으로 분석하고자 하였다. 연구 방법 : 2009~2019년까지 PubMed를 활용하여 Elderly, Health, Occupational therapy가 들어간 제목과 초록이 존재하는 연구논문을 분석대상으로 선정하여 초록의 단어들을 수집하였다. 수집된 정보를 통해 연도별 발생 논문 편수, 핵심어 분석, 연도별 핵심어 분석, 단어들 간의 관계성을 분석하였다. 결과 : 2009-2019년에 발표된 논문은 9,941편이며, 2009년부터 점차적으로 증가하여 2017년 또는 2018년에 최다 빈도를 보인 후 2019년에 감소하는 추이를 보였다. 최근 5년간 빈도수가 많은 단어는 Care, Group, Intervention, Pain, Treatment, Work이었다. 최근 11년간 평균적인 빈도수를 기준으로 단어 간의 관계성을 파악한 결과, Function, Health, Intervention, Participation이 단어들 간의 높은 관계성을 보였다. 결론 : 본 연구는 텍스트마이닝이라는 새로운 연구방법을 적용하여 작업치료의 동향을 실증적, 체계적으로 분석하여 거시적이고 종합적인 결과를 제시했다는 점에 의의가 있다. 이를 토대로 노인과 관련된 작업치료 임상 및 연구 현장에서 새로운 연구방향을 설정하는데 도움이 될 것으로 기대한다.
