  • This paper is proposed a wavelet-based the order statistics MAD(Median Absolute Deviation) method of image fusion of Multi-image contaminated with visible image and infrared image. also The method of compared and defined the threshold the wavelet coefficients using MAD of the wavelet coefficients of the detail subbands was proposed to effectively fusion which of selected the high quality image of the two images. The existed fusion rule may be possible to get the distorted fusion image especially by the distortion in the relation between the pixel and indicator of two images in the existed fusion rules. In order to complement the disadvantage, the threshold of the proposed method sets up the image statistic and excludes the distortion. The hardware design is used FPGA of Xilinx and DSP system for the image fusion and compressed encoding of the proposed algorithm. Therefore the proposed method is totally verified by comparing with the several other multi-image and the proposed image fusion.

  • Disagreements between the technical environment and the conventional library catalog have caused a re-clarification of International Cataloguing Principles (ICP). Review is under way to finalize the publication of RDA (Resource Description and Access) in late 2009 by the Joint Steering Committee for Development of RDA. The impending RDA is based on FRBR (Functional Requirements for Bibliographic Records) which re-explains the bibliographic universe focused on entities, attributes and relationships between resources, but tries to maintain MARC as an encoding format for RDA. In this study, firstly FRBR, ICP and RDA were analyzed. Secondly, we propose 3 scenarios of RDA implementation: the future cataloging system based on the FRBR Entity, using a semantic web structure, and the scenario using the existing MARC format with some small changes. Finally, by examining response patterns of overseas bibliographic institutions, we present a set of urgent issues for future directions of bibliographic contro in Korea which includes, but not limited to, relationship between RDA/FRBR and KCR (Korean Cataloging Rules), continuation of KORMARC and authority control.

  • This study is to find a resource description methods applying RDA 2020 through comparing original RDA and RDA 2020, identifying the characteristics of RDA 2020, and describing practical resources focusing on manifestation applying the rules of RDA 2020. Several things should be considered for practical cataloging manifestation by RDA 2020. First, it is necessary to figure out which among the four recording methods are allowed by the elements of entities. Second, each library should develop its own application profile which specifies the elements be used for the resource description, supports the practical resource description, and makes effective resource description based on minimum description. Third, a template for encoding format could be created based on the application profile. This study will be able to provide practical help when cataloging librarians describe resources with applying RDA 2020.

  • This study is to grasp LRM's feature and applications plan to reflect LRM to cataloging related standards and individual system through comparing and analyzing LRM with the FR model in terms of entities, attributes, and relationships. The application plan is suggested as follows. First, the entity can be extended by defining sub-entities of each entity in the standards and the individual system in order to reflect LRM, even though entities such as families, groups, identifiers, authorized access points, concepts, objects, events, agency and rules have been deleted in LRM. Second, the attribute should be subdivided in the standards and the individual system in order to apply LRM, though many attributes have been changed to relationships for linked data and decreased in LRM. In particular, more specific and detailed property names in the standards and the individual system should be clearly presented, and the vocabulary encoding scheme corresponding to each property should be also developed, since properties with similar functions or repetition in various entities, and material specific properties are generalized and integrated into comprehensive property names. Third, the relationship should be extended through newly declaring the refinement or subtype of the relationship and considering a multi-level relationship, since the relationship itself is general and abstract under increasing the number of relationships in comparing to the property. This study will be practically utilized in cataloging related standards and individual system for applying LRM.

  • The purpose of this study is to examine the perception of RDA by university library librarians and the level of perception of emotions, familiarity, understanding, introduction, obstacles, and education, and to secure basic data to improve awareness. The data needed for the study were obtained through a survey of 76 librarians in 4-year university libraries. As a result of the survey, 67.1% of librarians had listened to RDA, and school classes were the highest at 51.0% of cognitive means. Second, librarians perceived that they were more positive emotions than negative emotions about RDA, and that they were not familiar with RDA-related principles or concepts. In particular, it was recognized that the RDA itself and FRAD were not more familiar. The librarian recognized that they understood RDA-related principles or concepts at a normal level, and in particular, recognized that they did not further understand the authority and encoding. Third, librarians recognized the introduction of RDA at a slightly higher level than usual, but among the questions, 'RDA replaces AACR2' was recognized at a normal level. The librarian recognized the obstacles to the introduction of RDA at a higher level than usual, and in particular, the lack of education related to RDA was highly recognized. Fourth, librarians recognized the need for RDA-related education at a high level, especially the use of RDA Toolkit, changes in RDA records, differences between RDA and AACR2, and the need for RDA and MARC21-related education. In this study, based on the research results, a plan to improve librarian awareness of RDA was proposed.
