연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

전 세계적으로 미세먼지(particulate matter, PM)와 사망률유병률 증가의 관련성이 보고되면서 다양한 연구가 수행되었으며, 우리나라에서는 1990년대 후반을 기점으로 PM에 대한 중요성을 인식하고, PM에 대한 다양한 연구가 수행되었다. 본 연구에서는 '미세먼지' 관련 연구들의 주제를 분류하고, 각 주제별 연구 동향을 확인하기 위해 Research Information Sharing Service (RISS)에 게재된 미세먼지 관련 2,764편의 논문을 대상으로 Latent Dirichlet Allocate (LDA) 분석을 수행하였다. 연구 결과, 총 10개의 주제로 분류하는 것이 가장 적합하였으며, 미세먼지 관련 연구주제는 '미세먼지 저감(Topic 1)', '정부 정책 및 관리(Topic 2)', '미세먼지 특성(Topic 3)', '미세먼지 모델(Topic 4)', '환경교육(Topic 5)', '바이오(Topic 6)', '교통수단(Topic 7)', '황사(Topic 8)', '실내 미세먼지 오염(Topic 9)', '인체 위해성(Topic 10)'의 주제로 분류할 수 있었다. 특히, '정부 정책 및 관리(Topic 2)', '미세먼지 모델(Topic 4)', '환경교육(Topic 5)'. '바이오(Topic 6)' 관련 연구주제들이 시간에 따라 전체 논문에 대한 비율이 증가하는 추세를 보여 성행하는 것을 확인하였다(linear slope>0). 본 연구의 결과는 미세먼지 관련 다양한 분야의 연구자들에게 새로운 문헌 고찰의 방법론을 제시하고, 미세먼지 분야의 역사와 발전에 대한 이해를 제공했음에 의의가 있다.

Abstract AI-Helper 아이콘AI-Helper

The particulate matter (PM) has emerged as a hot topic around the world as it has been reported that PM is related to an increase in mortality and prevalence rates. In South Korea, the importance of PM has been recognized since the late 1990s, and various studies on PM have been conducted. This stud...

  • 본 연구는 국내 미세먼지 관련 연구들을 대상으로 토픽모델링 중 LDA를 적용하여 연구주제를 분류하고 그에 따른 연구동향을 분석하는 새로운 문헌고찰 방법론을 제시하였다. 하지만, 비지도 학습모델인 LDA 특성상 분류된 주제에 대해 연구자가 직접 해석해야 하는 한 계점이 존재하였다.
  • 본 연구는 국내 학술 DB 사이트인 RISS에서 1991년부터 2022년 9월까지 총 32년간 출판된 ‘미세먼지’ 주제 관련 논문(D=2,764)을 추출하여 토픽모델링을 수행하였으며, 국내 미세먼지 분야 연구의 주제 분류 및 역사에 대해 논의하였다
