Harmonization for scientific radio use such as radio astronomy and commercial business radio use such as
5G cellular networks must be an important common subject among all commissions A-K of which the URSI
can study and derive a fair solution to keep using radio resource from various viewpoints. In particular,
demand for commercial radio uses has been drastically increasing for these decades in global while scientificradio uses have a huge impact in origin of the universe and other academic progress. Conventionallyelectromagnetic interference between scientific and commercial radio uses has been taken care in several
venues; ITU-R, CISPR. Regional and international regulators have been making various rules andrecommendation to harmonize commercial and non-commercial radio uses considering benefit versus risk
for individual radio users, but it seems insufficient in a scientific reason for some cases due to urgent demands,
political reasons etc. For this discussion on harmonization for non-commercial scientific and commercial
business radio uses, we have been taken into account in several events of URSI, i.e. special sessions onURSI-ITU in GASS2011, AP-RASC2013 and JRSM2015. However, such argument has not been converged
yet while increasing urgent and serious problems to be solved. The reason why the URSI is a best venue todiscuss on the harmonization is obvious because URSI is a community of mature representatives of scientific,commercial, and other radio uses. Scientific use side could be represented in commissions F, G, H, and J andcommercial use side could be from standardization of cell operators, industry alliance, and radio
broadcasting association in commissions C, D, F, and K while mutual benefit and measurement have been
discussed in particularly commissions A,B, and E. URSI-Japan has been trying to establish a venue;“Regulatory science center for harmonization of scientific, commercial and other radio uses,” by applying
for the Master plan2014, 2017, 2020 and the Future academic promotion design 2023 of the Science Councilof J`APAN(SCJ) to make a consensus by scientific approach for making global rules and on promoting social
services and industrial innovation because radio is a global common resource to achieve most of the SDGs.

This public lecture in URSI-GASS2023 will approach to resolve remained issues in the harmonization with“regulatory science,” that is a multidisciplinary concept and subject. Regulatory science has been applied for
medicine and medical devices because risk versus benefit to apply newly invented medicine and devices tomedical healthcare can be scientifically analyzed with numerical evaluation. Then a guideline or regulation
for the medicines and devices can be made with scientific manner. Regulatory body will examine themedicines and devices compliant to the regulation. A plan and tasks of the regulatory science center for theharmonization of radio uses will be introduced to promote R&D for radio resource management for SDGs.
