안녕하세요.

특정 저널 서식에 따라 조금씩 연습을 하는중인데, 예측할수 없는 컴파일 에러들이 발생하여 많은 시간을 소비하게 만듭니다.

어떤 이유에서인지 몰라도 현재 Tex 파일을 첨부할 수 없어서, 제가 관련 내용을 아래에다 paste 했습니다. 컴파일 해보시면 아시겠지만, 수많은 에러가 발생합니다. 그 중에서 공통적으로 "head_foot/DOI not found" 와 "head_foot/dates not found" 와 같은 에러들이 보이는데, 제가 작성한 서식을 보시면 아시겠지만, 실제로 "head_foot" 과 관련한 코멘트가 있습니다. \includegraphics{head_foot_DOI} 그리고 \includegraphics{head_foot_dates} 를 보시길 바랍니다. (본문에서 관련부분의 에러가 포함된 부분을 Bold Style로 표시를 했습니다!!!)

지금 File Not Found 라는 말 자체가 어떤 파일을 첨가하지 않았다는 것인지, 아니면 path를 지정하는데 문제가 생겼다는지 알수가 없네요. 참고로, 제가 보낸 서식은 해당저널의 Latex Template을 그대로 사용하고, 다만 특정부분을 첨가하거나 변경했을 뿐, 이러한 것들은 발생한 에러와는 전혀 관계가 없습니다.

그런데, 이러한  error message에도 불구하고 PDF 파일이 하나 만들어졌는데, 나름대로 체대로 출력이 된 것 같습니다. 

어떻게 된 일인지 잘 모르겠습니다. 한번 아래 내용을 컴파일해보시고 관련 에러를 해결할 수 있는 방법을 알려주시면 감사하겠습니다.
