  • The aims of this study are to investigate the influence of the newly developed cataloging rule, RDA on the LIS cataloging education and to propose Korean LIS cataloging curriculum in a time of RDA. This study specially intended to examine the coexistence of the AACR and RDA and its implications on the LIS cataloging curricula design in the limited time of the course of study. For this purpose, this study examined the rapidly changing cataloging circumstances and how it affects on the cataloging education in LIS. This study also explored the students' as well as instructors' opinion and demand on cataloging education specially regarding RDA. As a result, this paper designed a cataloging education model including RDA curriculum and it also suggested cataloging syllabus based on the education model.

  • Digital RDA system is retransmit into the opposite direction of the incident signals. Digital RDA system have a disadventage that this system do not signal classification in multipath environment. because multipath signal is shown as vector sum of multipath signal, digital RDA system required complex signal process for multipath signal classification. In this paper, to solve these problem we propose hybrid digital RDA system which combination of the MUSIC algorithm and the digital RDA system. Proposed system has two modes. First mode is digital RDA mode. Secornd mode is digital beamforming mode. Digital RDA mode is used in situations where the less the impact of multipath. Digital beamforming mode is applied to multipath effects is greater. In secornd mode, we find optimal path using MUSIC algorithm. After than the proposed system uses only the optimal path. Through the proposed system in a multipath environment with digital RDA can be used to supplement a disadvantage.
