概要	A risk-benefit assessment is a systematic evaluation of the potential harms and benefits of a proposed research study, documented in ethics committee applications. The Belmont Report (1979) established the principle of beneficence—maximizing benefits while minimizing harm—as a cornerstone of research ethics. Regulatory frameworks (45 CFR 46.111 in the U.S., equivalent in other jurisdictions) require ethics committees to determine that risks are reasonable in relation to anticipated benefits before approving research. This assessment is not a simple calculation (risks + benefits) but a qualitative judgment incorporating probability, magnitude, and distribution of harms and benefits.	Submitting a research protocol to an ethics committee (IRB, REC, or equivalent) is a mandatory procedural gateway in human subjects research. The application process requires researchers to document their study design, justify scientific rationale, disclose risks and benefits, provide participant protections (informed consent forms), and address ethical considerations. The submission includes a completed ethics application form, protocol document, consent forms, researcher CVs, and evidence of institutional support. This standardized process enables ethics committees to conduct rigorous, timely, and consistent review before research commences.
