  • Digital Twin for Land(DTL) is one of the national work projects in the Korean New Deal but there aren't still any standards and technical guides which would need to construct the DTL. This study presents the policies to develop reference model and data model based on geo-spatial information standards to ensure interoperability for the DTL. In this paper, we first extract the implications through reviewing definitions of Digital Twin used in various literatures and international standardization trends on Digital Twin. In addition, this study attempts to conceptualize the DTL through various ways such as defining the DTL and characterizing DTL domains. Finally, we propose three policies on the standardization of the DTS: (1) DTS reference model by using RM-ODP, (2) three-steps hierarchical data models, and (3) model registry to manage the data models efficiently. The proposed policies of the study would contribute to establish a way for DTS's standards development over the coming years.

  • The purpose of this study is to develop a practical model for enhancing cooperative virtual reference services of public libraries in the nation. The research methods include an examination of model cases from Europe and the V.S. and also an electronic questionnaire survey of 375 public librarians (73% response rate). The study results suggest the need for 'a collaborative virtual reference room' which consists of the collaborative reference database, virtual reference desk, guidance and instruction designed by age groups and/or subjects.

  • In this paper, we present a construction method using perspective model which allows for the representation of the motion of a planar surface under perspective projection. The motion parameters are obtained by minimizing a disparity measure between the region in the current frame and the mapped region in the previous frame. The frames are constructed with dynamic panoramic image using a fixed reference or a time varying reference. By experiment, panoramic image proposed in this paper represents contents more efficiently than static image or video, and has a high volume reduction ratio.

  • The Reference Model for an Open Archival Information system(OAIS) was recommended for developing digital archives effectively and for implementing interoperability and resource sharing between digital archives. But as the Reference Model is high-level recommendation, it does not specify a design and an implementation. Therefore, this study investigates the architecture of several digital archives, suggestes three strategies for persistent archive, and proposes the conceptual model for developing trusted, persistent, and secure digital archive.

  • The method that selects reference points for interpolation is very important in Digital Elevation Model. However, there is no definition of an accurate standard until now, so users select the reference points for interpolation at their option. This paper aims to study on the accurate selection of the reference points for interpolation of DEM. This paper analyzed the method using the number of points and the reference points selection method by using the average distance calculated, from irregular points. Based on the analysis of the results, it shows that the Kriging method applying of the average distance is more efficient in construction of DEM.

  • As the number of Web reference resources are gradually increasing, reference librarians have to create a Web-based reference resources site. This site includes links to the Web reference resources of good quality, so that reference librarians and users will become accustomed to using these resources. This Study first explores the function of the Web-based reference resources site. Next, it carries out a survey of the current trends in america and Korea. Finally, a model Web-based reference resources site for academic libraries is developed.

  • In this paper, we designed an interoperability evaluation system based on technical reference model, HanTRM (Technical Reference Model) and the information technology architecture methodology, TAProcess (Technical Architecture Process). TAProcess provides standardized procedure and methodology for the efficient installation, management and operation of information technology. HanTRM can be used as a referencial basic framework for all organizations which are starting to make technical reference model. We propose a method that utilize HanTRM and a procedure that evaluates interoperability between information systems to design interoperbility evaluation system. So, this interoperbility evaluation system will be more usefully applied to organizations.

  • In this study, a methodology of synchronous control which can be applied to position synchronization of a multi-axes driving system has been developed. The synchronous error is caused by model uncertainties and disturbance at each axis. To overcome these problems, the synchronous control system of each axis has been composed of reference model, speed and synchronous controllers. The speed control system has been designed to follow speed reference. And the synchronous controller has been designed to keep minimizing the position synchronous error by reference model and H$\sub$ / approach. By the proposed method, position synchronous control system can be easily extended to two or more axes driving system. The effectiveness of the proposed method has been demonstrated by experiment.

  • This study presented the necessity of the development of a digital reference service systems as a method for direct information service in the library on the internet. The purpose of this research is to find commonalities for building a model of digital reference service. This study used qualitatives methods(elite interviews and document analysis) to extract accumulated knowhow from fourteen expert services sites which are similar with reference services in the library. For effective management of the digital reference service, it is necessary to have a digital reference service librarian who is well versed in the inner workings of the service and in the knowledge the service deals with.

  • The biological resources research data around the world are not only very critical themselves but should be shared and utilized. Up to now, the biological resources have been compiled and managed individually depending on the purpose and characteristics of the study without any clear standard. So, in this study, the data reference model would be suggested which is applicable in the phase ranging from the start of the construction of the information system and which can be commonly used. For this purpose, the data model of the related information system would be expanded based on the domestic and foreign standards and data control policy so that the data reference model which can be commonly applicable to individual information system would be developed and its application procedure would be suggested. In addition, for the purpose of proving the excellence of the suggested data reference model, the quality level would be verified by applying the Korgstie's data model evaluation model and its level of data sharing with the domestic and foreign standards would be compared. The test results of this model showed that this model is better than the conventional data model in classifying the data into 4 levels of resources, target, activities and performances and that it has higher quality and sharing level of data in the data reference model which defines the derivation and relation of entity.
