This study deals with the user task that is the goal of development of RDA (Resource Description & Access), an international standard for future bibliographic description. RDA seeks to implement the user task based on FRBR-FRAD model. User task could be composed of two areas: (1) find, identify, select, and obtain of bibliographic resources in information seeking and (2) find, identify, clarify, and understand of entities related to resources (i.e., person, family, corporate, concept, etc.). This research analyzes how the resource is defined with entity, attributes, and relationship in RDA based on the conceptual model of FRBR-FRAD. And this finally shows the ways of supporting user task in RDA.

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.
