The purpose of this study is to develop a collaborative print journal preservation model for the medical libraries in Korea. After reviewing previous studies and advanced preservation practices, a survey was administered to the members of the Korean Medical Library Association to collect data about the present states of journal weeding and storage space as well as their needs and preferences for collaborative preservation. Based on the analysis, a hybrid model, consisting of centralized and distributed archives, is proposed with MEDLIS as infra structure. Detailed characteristics and three phases of implement strategies are described. Finally, recommendations for the Korean Medical Library Association to the successful substantiation are suggested.

The purpose of this study is to develop a collaborative model for the archiving and preservation of an electronic book(e-book). In this study the way of the archiving and preservation for the e-book to deal with the technology evolution was suggested. Accordingly, the survey was made for obtaining the present status of the production and distribution of the domestic Online e-book. It is the same as the operation status of the archiving and preservation for the Online e-book worldwide. A collaborative model for accessible to preserved data, regardless of time period, was proposed for archiving the e-book, based on the OAIS reference model. There are three different models, suggested for domestic; the safe place model by law, the individual preservation/Peer-to-Peer model, and the preservation center model for e-book archiving. Among them, the safe place model by law was proposed for the optimum model of archiving an e-book at present.

The 3rd Library Development Plan raises the need to secure space through the establishment of a regional repository library as the issue of holding books is highlighted as a common problem in public libraries. The Korean Library Law Act also impose the responsibility of integrated management of local library materials on the regional representative library. Accordingly, this study aimed at Busan Metropolitan Library, which is operating a collaborative repository in earnest among regional representative libraries, and investigated the operation status of the collaborative repository and the perception of public librarians about the collaborative repository. The data necessary for the study were obtained through surveys, interviews, field surveys, and internal data analysis. Through this, the purpose of this study was to provide basic data that will help the Busan Metropolitan Library to operate the collaborative repository efficiently in the future, and at the same time, to present basic data that can be used as a reference for the operation of the collaborative repository of the representative libraries of other regions.

To promote recommendation services through prediction quality, some privacy-preserving collaborative filtering solutions are proposed to make e-commerce parties collaborate on partitioned data. It is almost probable that two parties hold ratings for the same users and items simultaneously; however, existing two-party privacy-preserving collaborative filtering solutions do not cover such overlaps. Since rating values and rated items are confidential, overlapping ratings make privacy-preservation more challenging. This study examines how to estimate predictions privately based on partitioned data with overlapped entries between two e-commerce companies. We consider both user-based and item-based collaborative filtering approaches and propose novel privacy-preserving collaborative filtering schemes in this sense. We also evaluate our schemes using real movie dataset, and the empirical outcomes show that the parties can promote collaborative services using our schemes.

The engineering design process is a creative process, and the designers must repeatedly apply Undo/Redo operations to modify CAD models to explore new solutions. Undo/Redo has become one of most important functions in interactive graphics and CAD systems. Undo/Redo in a collaborative CAD system is also very helpful for collaborative awareness among a group of cooperative designers to eliminate misunderstanding and to recover from design error. However, Undo/Redo in a collaborative CAD system is much more complicated. This is because a single erroneous operation is propagated to other remote sites, and operations are interleaved at different sites. This paper presents a multi-user selective Undo/Redo approach in full distributed collaborative CAD systems. We use site ID and State Vectors to locate the Undo/Redo target at each site. By analyzing the composition of the complex CAD model, a tree-like structure called Feature Combination Hierarchy is presented to describe the decomposition of a CAD model. Based on this structure, the dependency relationship among features is clarified. B-Rep re-evaluation is simplified with the assistance of the Feature Combination Hierarchy. It can be proven that the proposed Undo/Redo approach satisfies the intention preservation and consistency maintenance correctness criteria for collaborative systems.

Efforts to establish a joint preservation facility for library materials are being discussed in the regional representative libraries recently, but this is mainly a movement in public libraries. This study aimed to provide a model for a joint preservation facility construction and management especially for the National Universities Library in Busan/Gyeongnam area. For this job, after analyzing the current situation, this study focuses on 1) estimated size of the planned facility calculated by investigating the size and equipment, operation policy, collection quantity and saturation status of participating library archives, 2) strategies for construction, proposed a joint preservation architecture construction management model such as organization and human resources, and standards for transferring materials.

This study was conducted to investigate the materials deposit policies and service policies of overseas collaborative repositories and provide practical data that can be referred to the management of the collaborative repository in Korea. For this purpose, this study tried to analyzed websites of 7 collaborative repositories and related data. Materials deposit policies were focused on duplicate materials, criteria of materials to be accepted, ownership and withdrawal and service policies were focused on on-site services and off-site services including circulation and document delivery service(electronic copy and photocopy). The results of this study can be used as practical data for the establishment of guidelines for collaborative repository in Korea.

We conducted a survey in collaboration with the Chungcheongbuk-do Office of Education to assess the current status of collections in public libraries affiliated with the Office of Education. The objective of this survey was to identify the current challenges and determine when these libraries are expected to reach a state of collection saturation. Libraries under the jurisdiction of the Chungcheongbuk-do Office of Education are currently facing significant challenges due to severe collection saturation. This underscores the pressing need for the systematic expansion and operation of a collaborative preservation library for a swift response. In the future, it appears that the focus during the transfer process will primarily be on transferring collection-oriented materials. Given the difficulty in providing preservation facilities at individual library levels, materials with preservation value, such as rare books and specialized resources, will need to be transferred to the collaborative preservation library. Additionally, the development of policies and regulations related to material preservation seems necessary. Furthermore, when transferring materials to the collaborative preservation library in the future, it appears that criteria for material transfer will be needed, particularly concerning issues such as a decrease in usage rates for less frequently accessed materials. Subsequent research should consider conducting a survey on the collection saturation status of public libraries under local governments in order to assess the overall need for collection expansion in all public libraries within Chungcheongbuk-do.
