No need to be flippant and arrogant, thanks.
I lived in South Korea for over 6 years, myself and have studied Korean history extensively. Fascinating stuff.
With the 2,100 years of recorded Korean history, they for nearly all of it, have not been noted for their science. Perhaps for a brief flourish in the 15th century and the last few decades.
As for the Mongols, I certainly wouldn't classify them as a scientific civilization but they actively transmitted a fair amount of technology through their conquests to the Korean Peninsula which kickstarted the aforementioned 15th century brief scientific flourish. That includes the beloved Hangul script that was supposedly created out of thin air and has been claimed by Koreans to be the most scientifically accurate script in the world.
Anyway, I laid out solid reasoning for this six years ago when the last last iteration came out. Plus, this is off topic and is taking away from the well designed Russian Civ which definitely deserves the scientific focus.
