Abstract
In the News from Japan column in the March/April 2021 issue [1], a brief introduction of the Ninth International Symposium on Electrical Insulating Material (ISEIM) was described. It was also described that the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q(t)$</tex> method developed by Prof. Tatsuo Takada of Tokyo City University had been introduced in a seminar taking place in the Ninth ISEIM. As mentioned in that column, the principle of the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q(t)$</tex> method itself is well known. However, this revisited method is very innovative and truly useful. Regarding this, although a measurement example of the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q(t)$</tex> method was briefly introduced in the above March/April issue, more examples are being introduced in detail in this issue and the next issue.
