제32차 대한척추외과학회 춘계학술대회 May 29(Fri)-30(Sat), 2015 Alpensia Resort Convention Center, Pyeongchang

인사말 대한척추외과학회가 1984년 창립되어 회원 여러분들의 희생과 노력으로 끊임없는 발전을 이루어 올해로 창립 30주년을 맞이하였 습니다. 우리나라 척추관련 학회 중 가장 오랜 역사를 가진 학회로 해외의 다른 학회와 비교해서도 뒤지지 않는 학회로 성장하였고, 회 원들의 연구 실적도 국제학회 발표 및 우수 연구 학술지를 통해 그 업적이 인정되고 있습니다. 이번 제 32차 대한척추외과학회 춘계학술대회에서는 학회의 국제 화를 위해 몇 가지 새로운 시도를 하였습니다. 학술 프로그램을 영 문으로 만들어서 해외 참가자들과 외국에 우리 학회의 발전상을 알 릴 수 있도록 하였고, 영어 세션을 개설하여 국내 연자뿐만 아니라 해외 연자들에게도 발표의 기회를 제공하였습니다. 그리고 초록집 을 대한척추외과학회지 proceeding으로 발간하고, 학술대회 초록 을 모바일 홈페이지에서 열람이 가능하도록 하였습니다. 학회의 발전과 밝은 미래를 위해 회원 여러분들의 적극적인 참여 를 부탁 드립니다. 감사합니다. 대한척추외과학회 회장 목 차 03 Program Summary 04 Program May 29 (Fri) 14 Program May 30 (Sat) 18 Poster 19 구연발표, 포스터전시 & 등록 안내 20 숙박안내 김기택
