The Graduate School of Nursing was established in July 2000 and had a history of over 20 years for nurturing professional nurses and the development of the nursing profession. With the start of the domestic professional nursing program in 2003, the graduate school opened a nursing course specializing in the elderly, emergency, and anesthesia, a nursing course specializing in oncology in 2012, and a nursing course specializing in infection control in 2018. According to changes in the medical field, four courses are being operated for the elderly, emergency, oncology, and infection management.
Currently, nursing is positioned as a major medical profession in the changing medical reality due to specialization and diversification. To meet these social changes and people's health care needs, there is a need to develop nursing science as well, and the Graduate School of Nursing is making efforts to develop nursing science in line with this.
The Graduate School of Nursing consists of faculty members with many years of clinical practice experience as professional nurses, faculty with excellent research capabilities, and professional nurses in each field who are in charge of clinical practice in the professional nurse course as on-the-job instructors. This is to provide the best educational opportunity to build professional nurses' research and practical skills by connecting nursing in nursing in the discipline.
