KORYO poomse symbolizes "seonbae" which means "learned man" characterised  by a strong spirit.  KORYO is the name of an ancient dynasty -- (AD918-1392).  The english word korea is derived from the name KORYO.  Koryo's legacy to the Korean people is very significant, as they successfully defeated and thus defended Korea from the attacking aggression of the Mongolian Empire, who were sweeping the known world at the time.  In 1234, Koryo men invented a type of metal new to the world.  They also created the famous Koryo ceramics (1398-1468).  These precious materials were greatly desired by the Mongolians, who occasionally tried but were unsuccessful in sweeping across the country.
