  2. About Seoul National University

    Seoul National University

    Seoul National University is a public research university located in Seoul, Republic of Korea, ranked 50th in the world and 8th in Asia by US News and World Report, and 24th in the world in publications by the Science Citation Index Founded in 1946, Seoul National University was the first national university in South Korea, and served as a model for the many national and public universities in the country. Seoul National University has been recognized for its leading role in Korean academia. 

    Seoul National University Hospital is located in Gumi-dong, Bundang, Seongnam, Gyeonggi-do, South Korea. It began its first treatment on 10 May 2003. It was set up due to a rapid increase in demand for geriatric treatment and the government's request for the establishment of a medical facility for local residents. Seoul National University Bundang Hospital, consists of 6 departments : the Geriatric Medical Centre, Heart Centre, Cranial nerve Centre, Lung Centre, Articulation Centre, and the Health Improvement Centre, and 23 departments, such as Internal Medicine, Surgery, Chest Surgery, Neurosurgery, Orthopaedics, Plastic Surgery, Obstetrics and Gynaecology, and Pediatrics. There is also an accident and emergency department.
