\section{Why \LaTeX ?} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{frame}[t,fragile]{Why \LaTeX ?}\small
\vspace*{-1em}
\begin{itemize}
\item \textcolor{GSHSRED}{\textbf{Free:}} No cost to make and to view.
\item \textcolor{GSHSRED}{\textbf{PDF:}} Its result is the pdf format, the standard document granted by ISO.
\item \textcolor{GSHSRED}{\textbf{No mouse:}} You can make a document just by typing keyboard.
\item \textcolor{GSHSRED}{\textbf{Speed:}} The more proficient, therefore, the faster.
\item \textcolor{GSHSRED}{\textbf{Look:}} Nice and boundless mathematical formulas.
\item \textcolor{GSHSRED}{\textbf{Vector format:}} Images and graphs of a vector format (e.g. eps, pdf) keep their quality.
\item \textcolor{GSHSRED}{\textbf{Codebase:}} Fast conversion between papers and presentations.
\item \textcolor{GSHSRED}{\textbf{Unconstrained from OS:}}
\item \textcolor{GSHSRED}{\textbf{Light:}} Minimized GUI. Keyboard shortcuts are replaced by commands.
\item \textcolor{GSHSRED}{\textbf{WYSIWYM:}} Just writing text. Low computer resource. No lag.
\item \textcolor{GSHSRED}{\textbf{Automatic formation of ToC, LoF, LoT, Labels of equations, figures, and tables, ...}}
\end{itemize}
\end{frame}

\begin{frame}[t]{But...}\small
\begin{itemize}
\item \textcolor{GSHSRED}{\textbf{Unfamiliar:}} In general, one uses WYSIWYG style.
\item \textcolor{GSHSRED}{\textbf{Minimized GUI, Codebase:}} Higher entry barrier for beginner.
\item \textcolor{GSHSRED}{\textbf{Weak support for 한글}}
