FYI,
This is a development note I have created before I go further. Still most of them are under idea level and I will verify one by one by doing the experiment. And, when necessary, I will revise and update it.

If you are interested, take it! I would appreciate if you let me know any opinion/suggestion/idea.
Thanks and Regards
