The Cultural Merit Medal is the second highest honor that can be conferred by the President of South Korea on individuals who have "rendered distinguished service" to the country. Hye-Sook was recognized for the contributions she has made by teaching, researching, and promoting Korean language and culture. The medal was personally conferred on Hye-Sook at a ceremony held in Korea on "Hanguel Day," an annual holiday celebrated on Oct 9, that commemorates the creation of Hanguel (the Korean alphabet) by King Sejong the Great in 1446.
