From 2003 to 2006, Euh Yoon-Dae, the current Chairman of President's Council on National Branding, Steering Committee of Korea Investment Corporation (KIC), and the former (15th) President of Korea University, drastically changed the image of Korea University, a change symbolized by the adoption of red wine over the traditional rice wine. He doubled the publication requirements required for faculty promotion and raised the ratio of the classes taught in English to 35% of all courses taught. He also required that core liberal arts classes be taught by full-time faculty and required every student except those in the Colleges of Engineering, Law, and Medicine to do a double major. He also signed academic exchange agreements with 172 universities overseas and dispatched 60% of administration staff to the world's top 100 universities for training.[38] Korea University also expanded its international-level facilities. It built the Centennial Memorial Samsung Hall, Hwajung Gymnasium, Tiger Plaza, and Hana Square, and also expanded educational and cultural spaces.[6]
