What is the Korea Stock Exchange index called?

I'm curious to know, could you please tell me what the specific name is for the index that represents the Korea Stock Exchange? It's an important aspect of understanding the performance of the Korean financial markets, and I'm sure many investors and traders would appreciate knowing the terminology associated with it. Is there a unique name that designates this index, or does it go by a more generic term? I'm looking forward to your clarification on this matter.
