Abstract

This research team extracted keywords from 953 papers published in the Journal of Dental Hygiene Science from 2001 to 2018 for keyword and centrality analyses using the Keyword Network Analysis method. Data were analyzed using Excel 2016 and NetMiner Version 4.4.1. By conducting a deeper analysis between keywords by overall keyword and time frame, we arrived at the following conclusions. For the 17 years considered for this study, the most frequently used words in a dental science paper were "Health," "Oral," "Hygiene," and "Hygienist." The words that form the center by connecting major words in the Journal of Dental Hygiene through the upper-degree centrality words were "Health," "Dental," "Oral," "Hygiene," and "Hygienist." The upper betweenness centrality words were "Dental," "Health," "Oral," "Hygiene," and "Student." Analysis results of the degree centrality words per period revealed "Health" (0.227), "Dental" (0.136), and "Hygiene" (0.136) for period 1; "Health" (0.242), "Dental" (0.177), and "Hygiene" (0.113) for period 2; "Health" (0.200), "Dental" (0.176), and "Oral" (0.082) for period 3; and "Dental" (0.235), "Health" (0.206), and "Oral" (0.147) for period 4. Analysis results of the betweenness centrality words per period revealed "Oral" (0.281) and "Health" (0.199) for period 1; "Dental" (0.205) and "Health" (0.169) for period 2, with the weight then dispersing to "Hygiene" (0.112), "Hygienist" (0.054), and "Oral" (0.053); "Health" (0.258) and "Dental" (0.246) for period 3; and "Oral" (0.364), "Health" (0.353), and "Dental" (0.333) for period 4. Based on the above results, we hope that further studies will be conducted in the future with diverse study subjects.

본 연구는 키워드 네트워크 분석 방법을 활용하여 치위생과학회지 2001년부터 2018년 3호까지 게재된 논문 953편의 키워드를 추출하여 연구 구조를 파악하기 위해 키워드 분석과 핵심어를 파악하기 위해 중심성 분석을 실시하였다. 그리고 5년 단위로 1기를 2001년부터 2005년까지, 2기를 2006년부터 2010년까지, 3기를 2011년부터 2015년까지, 4기를 2016년부터 2018년까지로 구분하여 연구동향을 분석하여 다음과 같은 결론을 얻었다. 치위생과학회지에서 도출된 총 1,454개의 단어 중에서 17년간 치위생과학회지 투고 논문에서 가장 많이 쓰인 단어는 'Health'이며 'Dental', 'Oral', 'Hygiene', 'Hygienist'에 관한 논의가 가장 활발하였음을 알 수 있었다. 중심성 분석을 통해 치위생과학회지에서 핵심이 되는 단어들과 연결되며 중심을 형성하고 있는 단어들은 'Health', 'Dental', 'Oral', 'Hygiene', 'Hygienist', 'Behavior' 등이며, 매개중심성 상위 단어들은 'Dental', 'Health', 'Oral', 'Hygiene', 'Student' 등으로 나타났다. 시기별 연결중심성 핵심 키워드를 살펴본 결과, 1기에서는 Health (0.227), Dental (0.136), Hygiene (0.136) 등, 2기에서는 Health (0.242), Dental (0.177), Hygiene (0.113) 등, 3기에서는 Health (0.200), Dental (0.176), Oral (0.082) 등, 4기에서는 Dental (0.235), Health (0.206), Oral (0.147) 등의 단어들이 나타났다. 각 시기별로 매개중심성은 1기에서는 Oral (0.281)과 Health (0.199)의 매개중심성이 높게 나타났으며, 2기에서는 Dental (0.205)과 Health (0.169)가 높게 나와 매개역할의 비중이 높다가 Hygiene (0.112), Hygienist (0.054), Oral (0.053) 등으로 매개역할의 비중이 분산되는 것을 알 수 있었다. 3기에서는 Health (0.258)와 Dental (0.246)의 매개중심성이 높게 나타났으며, 4기에서는 Oral (0.364)과 Health (0.353), Dental (0.333)의 매개중심성이 높게 나타났다. 이상의 결과를 바탕으로 향후 치위생학 연구에 있어 학문 주제에 대한 다양성과 다각화를 모색하여 많은 연구가 이루어지길 기대한다.
