He took the CEO title from Young Hwan Oh, who remains co-president. Oh is now working at the company's design center in Texas, according to a company spokesman. ''This appointment is carried out to strengthen the responsibility management and increase the business effectiveness through fast decision under the crisis situation,'' according to the company at that time.
