From the REPORT OF THE 13th GENERAL ASSEMBLY OF IMU [= International Mathematics Union], Dresden, Germany, August 15-16, 1998:
North Korea and Nigeria, have not paid any dues since 1990. Moreover, neither North Korea or Nigeria have answered the Union messages concerning their dues arrears. The General Assembly decided to cease/suspend their membership, if they do not answer to the EC renewed efforts after a year. However, North Korea is on the list of the Union of January 1, 2001 (so they paid the dues, finally).
Their entry in the directory published in 2002 looks as follows:
Democratic Republic of Korea - Group II
Adhering Organization
Academy of Sciences of D.P.R. of Korea
Dr. Jong Jae Bu
Vice Chairman, Mathematical Council
Scientific Deputy Director
Institute of Mathematics
Pyongyang Korea, Dem. People's Rep.
Committee for Mathematics
Academy of Sciences of D.P.R. of Korea
Dr. Jong Jae Bu
Vice Chairman, Mathematical Council
Scientific Deputy Director
Institute of Mathematics
Pyongyang Korea, Dem. People's Rep.
I could not find any info concerning Mr Jong Jae Bu using Google (I tried Chong Chae Pu as well).
Eight research papers authored by researchers of the institute were posted on the Web in November 2005; see
