\section{Introduction}
\subsection{Notice}
While you are preparing your paper, please take care of the following items:
\begin{enumerate}
\item [(1)] Abstract: 150 words or less.
\item [(2)] Key words: At least 3 items and at most 5 items.
\item [(3)] Authors: Full names, mailing addresses and emails of all authors.
\item [(4)] Tags (Formula Numbers): Use \label{A} and \eqref{A}. Remove unused tags.
\item [(5)] Acknowledgement: At the end of paper but preceding to References.
\item [(6)] Margins: A long formula should be broken into two or more lines. Empty spaces in the text should be removed.
\item [(7)] References: Use \cite{C1, 2, J1, Z} to refer to the specific book/paper in the text. Remove unused references. References should be given in alphabetical order with the following format: a) to books: author, title, publisher, location, year of publication; b) to articles in periodicals or collections: author, title of the article, title of the periodical (collection), volume, year, pagination.
\end{enumerate}
