I have finished the open seminar.
As I hoped that participants would understand the contents more easily,
I had to have some improvements or Kaizens in the previous materials and explanations.
Such works, （as you also know well, ) are very difficult.
Because, as usual, the improvements is likely to be increasing the contents.
However, the time of the seminar may not be changed.
Therefore It was neccessary for me to cut down previous contents,
and to shorten the description.
The result will have possibilities to make the seminar easy or complicated.
Now, I hope that my improvements were good for the participants.
