Abstract

Recently collaboration network is generated to find out experts in their field as potential collaborators in health care sector. In this paper, the co-author network of a National Cancer Center researcher was generated for identifying each researcher's role and collaborative research pattern. The co-author network of 2,437 authors was extracted from 1,194 SCI(E) publications from 2000 to 2010 and author's role was analyzed by author's centrality value. Centrality reflecting only the number of papers and centrality weighted by the paper number, impact factor, and authorship contribution was evaluated. On the comparison with simple degree centrality value and the weighted degree centrality, difference of value was statistically significant(t=11.66, p=0.00). Co-author network considering various variables of the paper provides more objective figure of researcher's role. This suggests that co-author network could be more effective in identifying potential collaborators.

최근 보건의료분야에서는 협동연구를 위한 연구팀을 구성하기 위해 협업네트워크를 구축하고 연구자 역할을 파악함으로서 분야별 전문가 집단을 도출하고 있는 추세다. 본 연구는 1개 전문암센터 연구자들을 대상으로 기관 내 연구자들의 역할을 분석하고 협동연구 형태를 확인하기 위해 공저자 네트워크 분석을 수행하였다. 분석 자료는 2000년부터 2010년까지 SCI(E)에 발표한 연구논문 1,194건의 논문 저자 2,437명을 대상으로 중심성 분석을 하였다. 공저자 네트워크는 논문 수만 반영된 단순 중심성 값과 논문 수, 학술지 영향력 지수, 저자 기여도가 반영된 가중치 중심성 값을 산출하여 연구자 역할에 유의한 차이가 있는지 분석하였다. 단순 중심성 값과 가중치 중심성 값에 의한 연구자별 순위는 통계학적으로 유의하게 차이가 있었다(t=11.66, p=0.00). 논문의 다양한 속성이 고려된 공저자 네트워크 분석 결과는 연구자의 역할에 대한 보다 객관적인 자료를 제공함으로서 협동연구 수행을 위한 분야별 전문가를 확인할 수 있는 자료로 활용이 가능할 것이다.
