Libraries and Museums have used archiving systems to preserve digital contents. Especially, university libraries mainly archive research resources including research papers. To the best of our knowledge, we proudly propose an educational repository oriented to archive overall educational process for the first time. To design the repository, we choose educational resources which need to be archived. Then, digital formats appropriate for long-term preservation are heavily discussed. Based on the design, we have practically implemented the system using representative repository software : DSpace, EPrints, Fedora, Omeka. Finally, educational resources of the specific subject are archived on each system, and the result of comparison is presented.

The goals of this research are to look into the logistics systems and to have a thorough grasp on the status of legal systems such as taxation and customs clearance practices and, further, to draw up an interoperable scheme seamlessly linking those two on a national scale. In this research we looked into the business process and related information of border-crossing logistics systems between B2B marketplaces. We also investigated the status of taxation systems and customs clearance practices in order to associate e-marketplaces with one another. We proposed interoperable scheme for seamless linking between B2B e-marketplace based on marketplace repository model.

The Digitalia MUNI ARTS - a local node of the LINDAT/CLARIAH-CZ research infrastructure at the Faculty of Arts of Masaryk University constitutes a repository in the Islandora system. It is used for long-term preservation of research data together with their research environment in the form of digital platforms. We transfer the digital outputs of humanities scholars research to the repository according to a set plan, which is based on best practice recommendations for project management and digital curation. In this paper, we present how the results of interviews with platform developers and infrastructure stakeholders translate into the curation workflow, and a resulting model for migrating digital platforms to the repository. Reflecting on three types of problems we encountered during the implementation of platforms into the repository - communication problems, problems of external dependence, and management problems - we describe a modification of the migration process. We present six recommendations for repository administrators and curators in an academic setting - holding an introductory meeting with developers, researching significant and relevant theories of knowledge domain, consulting license experts, prioritizing requirements, and preparing handover protocol and progress reports.

As the present single-layer repository concept requires too large an area for the site of the repository, a multi-layer repository concept has been suggested to improve the disposal density. The effects of the excavation damaged zone around the multi-layer repository constructed in the deep host rock on the temperature distribution in the repository were analyzed. For the thermal analysis of the multi-layer repository, the hydrothermal model was used to consider the resaturation process occurring in the buffer, backfill and rock. The existence of an excavation damaged zone has a significant effect on the temperature distribution in the repository, and the maximum peak temperatures of double-layer and triple-layer repositories can rise to $7^{\circ}C$ and $12^{\circ}C$, respectively depending on the size of the excavation damaged zone and the degree of decrease of the thermal conductivity. The dominant factor affecting the peak temperature in the multi-layer repository is the decrease of thermal conductivity in the excavation damaged zone, and the excavation damaged zone formed around the deposition hole has more significant effects on the peak temperature than does the excavation damaged zone formed around the disposal tunnel.

The management and deposit of paper document costs are increased gradually. Specially, it is too expensive to safekeeping paper document in the warehouse. Also paper based document system is exposed in several security problems. Therefore, demands of transformation process from paper document into electronic ones are quietly needed. Electronic document repository system is one of the best solutions for solving paper based document system issues. Electronic document repository system can reduce overall costs and provides some advantages in comparison with paper based document system. But, electronic document repository system has no formal methodology for guarantee safeties. Therefore, we suggest a security mechanism for establish electronic document repository system. Suggested security methodology can help for design of more secure electronic document repository system.

Many Korean financial firms have built knowledge management systems, however, most of the systems have fragmentary ideas or suggestions. This study proposes the model of ontology-based knowledge repository through which one could integrate knowledge for business use in the BPM environments. The knowledge includes implicit and explicit knowledge. library materials, documents, and information for experts as well. In order to get basic ideas for this model, case studies utilized interviews and surveys were conducted targeting at four Korean banks' knowledge managers, librarians and thirty staffs.

Nowadays XML is used for exchanging information in e-Commerce, especially B2B. Necessity of XML DBMS has being increased to efficiently process XML data. So a lots of database products for supporting XML are rapidly appeared in the market. In this paper, we made an XML DBMS system based on Generic Data Model. First we developed XML Adaptor based on Generic Data Model and added it on relational DBMS for developing XML DBMS. XML Adaptor is composed of Query Convertor and XML Repository System. The Query Convertor parse commands that are for XML data manipulation and then call the relevant component of XML Repository System for relational database operation. The XML Repository System handles relational database operations such as create, delete, store, and etc. In this way we can use a relational DBMS for manipulation XML data. Therefor we can build more economically XML DBMS.

In this paper, we designed a repository structure for components retrieval. The repository is consisted of data, process, and view for syntax analyzer, retrieval method, viewer, and reuse. We used enhanced spreading activation algorithm for components retrieval and showed the retrieval results. The retrieval result shows the components in order of high priority. Thus components reusability is improved.

In this study, the use statistics by type of data in the A university of a Institutional Repository(IR) with exponential growth in usage and the trend of changes in the access path for users to access A-IR were analyzed. In particular, it was verified that securing various exposure paths contributed to the spread of A-IR by focusing on the change in the approach path, and also confirmed that the method of communication between the ages, such as SNS, is used as the approach path of A-IR. Through this process, the company was planning to suggest the direction of operation, including diversification of exposure paths that activate the institutional repository.

A safety assessment of radioactive waste repositories is a mandatory requirement process because there are possible radiological hazards owing to radionuclide migration from radioactive waste to the biosphere. For a reliable safety assessment, it is important to establish a parameter database that reflects the site-specific characteristics of the disposal facility and repository site. From this perspective, solubility, a major geochemical parameter, has been chosen as an important parameter for modeling the migration behavior of radionuclides. The solubilities were derived for Am, Ni, Tc, and U, which were major radionuclides in this study, and on-site groundwater data reflecting the operational conditions of the Gyeongju low and intermediate level radioactive waste (LILW) repository were applied to reflect the site-specific characteristics. The radiation dose was derived by applying the solubility and radionuclide inventory data to the RESRAD-OFFSITE code, and sensitivity analysis of the dose according to the solubility variation was performed. As a result, owing to the low amount of radionuclide inventory, the dose variation was insignificant. The derived solubility can be used as the main input data for the safety assessment of the Gyeongju LILW repository in the future.
