머리말

 

경제 개발 5개년 계획과 중화학 공업 육성으로 우리나라의 화학 공업은 급속도로 발달하여 세계 속에 중화학 공업국으로 발돋움하고 있는 이때에 우수한 기능공이 절실히 요구되고 있음은 물론, 보다 안전하고 능률적인 조업이 시급한 실정임을 간파하여 이 교재를 편찬하게 되었다.

이 교재는 세계에서 유명한 GULF사가 사내 조업 기술 훈련 교재로 개발한 화학 공장 조업을 위한 교재이다.

이 교재는 현재 우리나라에서도 유수한 화학 공장에서 사용하여 좋은 성과를 거둔바 있는 일명 PILOT 교재란 이름이 붙은 우수한 교재이다. 이 교재의 특성은 주입식, 문답식, 도설로 되어 있으므로 누구나 쉽게 숙련할 수 있게 편집되었다.

이 교재 출간으로 중화학 공업 발전에 기여할 수 있는 계기가 되기를 바라는 마음 간절하며 교재 편찬에 수고해 주신 여러분께 심심한 감사를 드리는 바이다.
