Recently, the Ministry of Internal Affairs and Communications of Japan has reported on a plan for the "effective use of radio waves" to be promoted in the 2020s. This includes promotion of the effective use of public frequencies, reviews of frequency allocation and transition systems, and spectrum usage fee system. Based on the proposals in this study, concrete systems for revising related laws, such as the Radio Law, will be designed and implemented. In addition, the government will jointly conduct research and development as well as verification tests in cooperation with industry, academia, and government. A plan to improve the system for the effective use of radio waves will then be devised. This study examines the policy directions of the frequency utilization system that Japan plans to use for radio waves in the 2020s. The policy directions are analyzed selectively while considering the radio waves utilization system in Korea, and implications for domestic applications are derived. Based on the research from this study, analyzing the radio policies of advanced countries, including those of England and the United States, and utilizing them to establish an effective use plan of radio waves in Korea are deemed necessary.

In practice of urban redevelopment promotion projects, since the decision-making is dependent on the verbal agreements between the participants, planning changes are frequently occur. A master plan can be utilized as an effective feedback and adjusting means for decisions. It is a difficult to establish a master plan quickly and effectively to consider the large number of information. Effective decision support system that can storage and retrieval information items systematically and efficiently necessary when planning master plan is required. In this study, a data-warehouse prototype that supports the master planning at early stage was suggested. A metadata index database was developed by identifying information items of base survey results and master plan cases. Also user interface for information searching was presented. The applicability of the prototype was evaluated by case application. It was found that the prototype allows effective searching of desired information through meta data.
