%% 목차에 \subsubsection까지 단원이 번호와 함께 나오도록 한다.
%% article에서는 이미 3으로 지정되었으나, 그외에서는 2로 지정되어
%% \subsection까지만 번호가 목차에 나오도록 되어 있다.

%% 위와같은 재정의로 다음과 같은 문제가 발생한다.
%% 1. \part는 \partname~\thepart로 나오게 된다. 편~I
%% 2. \chapter는 \@chapapp{} \thechapter로. 장~1
%% 3. \section은 \sectionname~\thesection으로. 절~1
%% 4. 목차작성의 들여쓰기가 우리말 환경에 적당하지 않다.
%% 5. 페이지 heading의 글자체가 \slshape으로 바뀜으로서 우리말이
%%    불안정해진다.
%%
%% 이런 약점을 보완하기 위해 단원의 일련번호의 앞과 뒤에 끼워넣을
%% 모듬을 다음과 같이 설정한다.
