This is an old article from 2008
It can be considered an article that the author liked very much at that time.
But there are quite a few places that need to be deleted.
It may seem a bit out of date with current concepts.
I just wanted to use this as a souvenir for myself who was new to writing at that time.
I hope you readers will not enter if it is not suitable for you, and do not make excuses easily.
