In recent years, there have been tremendous increases in the field of radio-communication services and equipments. It means that the well-organized technical regulations for the radio-communication services and equipments are needed in order to protect the rights and interests of the radio-communication users. This study describes all the activities for improving the technical regulations of the short range radio-communication devices(srds) newly developed in the worldwide level. Technical regulations for the SRDs, which were newly developed or modified recently, are studied. In 2010 we amended technical regulations for the magnetically induced radio equipments, UWB, and unlicensed radio equipments used in 57-64GHz. Right after publishing "the Radio Waves Act" amended in 2010, we had to revised "the Conformity Assessment Method of the Type Approval and Type Registration". Its revised version is described in this study. It is the collection of the testing methods and procedures for all the broadcasting and radio-communications equipments regulated in Korea. The international activities in the field of spectrum managements and frequency harmonization is included in this study. We hosted the international meeting of AWF in Seoul, Korea from 13 Sep. to 16 Sep. 2010. We participated in the meetings of ITU-R Study Group 1 and its subsidary Working Parties 1A and 1B held in Geneva, Swiss in 2010. At these meetings, 8 contributions were proposed amendments of ITU-R recommendation SM.1541, SM.329 etc, and ITU-R Report SM.2153, SM.[RFID]. We attended the 3'th and 4'th meetings of the APT Conference Preparatory Group for WRC-2012 (APG 2012) held in Bangkok, Thailand from 8 March to 12 March, 2010 and Hongkong, China from 13 Dec. to 18 Dec., 2010, respectively. At the APG meetings, 8 contributions were proposed amendments

of APT common views for A.I. 1.2, A.I. 1.19, A.I. 8.1.1, etc.. We attended the 8'th and 9'th meetings of APT Wireless Forum(AWF) held in Tokyo, Japan from 29 March to 1 April, 2010 and Seoul, Korea dfrom 12 Sep. to 16 Sep., 2009, rspectively. The meetings of AWF covered the spectrum harmonization and the various aspects of emerging wireless systems to meet the upcoming digital convergence era for the Asia-Pacific region. We hope the results of work are to be the basis for improvement in field of radio-communication regulations and equipments in Korea.
