Speakers of the National Assembly of South Korea

Could you name All leaders of the unicameral legislature of South Korea? Since this is about Koreans, the first name is the surname and I edited it so the type ins are accurate to that. The "Is Name" on section 4 for editing acts on the Western naming system in that the last name is the family name and could work by simply typing in the last name but first needs last after. I adapted this where the Korean way works, where the first name works and last needs first in order to work.
