As the number of clinical studies in Korea is increasing and qualitatively improving, interest in safety and welfare of research subjects, which are subjects of clinical research, is also increasing. Researchers who conduct research on humans should know and follow established laws and regulations in relation to clinical research, be aware of research ethics guidelines, and voluntarily comply with them. We would like to briefly inform the researchers that the IRB (Institutional Review Board) of Chosun University Hospital, which was enacted in June 2016 and revised in September 2018, will be able to fully understand the ‘Ethics Guideline for Research Related Persons in Chosun University Hospital (Version 2.0)’. Therefore, researchers need to understand and comply with domestic laws and regulations regarding clinical research, understand the roles and responsibilities of IRBs in protecting research subjects, and study research ethics guidelines.
