京都大学 エネルギー科学研究科公開講座「大気環境と化学反応－空に漂う小さな粒子の上で起こっていること－」亀田貴之（エネルギー科学研究科 教授）

Picked video by video from Kyoto U OCW (mixed channel): title plainly names a teaching subject. Channel transcript sample: All three samples are substantive academic lectures/seminar talks (IT management course, bio-sensing research seminar, language-education colloquium) rather than ceremonies or promos, supporting a pick verdict with per-video selection.
