In 2020, the Busan metropolitan library took the lead in establishing an integrated library system (ILS) that integrates bibliographic data from 49 public libraries and 103 small public libraries. However, each library still builds bibliographic data individually and repeatedly, and the bibliographic data built by each library is only physically stored in an integrated DB. Therefore the improvement in work efficiency or data quality has not been achieved. This study aimed to analyze the construction processes and quality of bibliographic data in Busan public libraries and to suggest a new implementation strategy for an integrated environment. To this end, (1) the construction process of bibliographic data was investigated, (2) the quality of the constructed bibliographic data was objectively analyzed, and (3) four implementation strategies were suggested based on critical problems. The implementation strategy aims not only to improve the quality of bibliographic data, but also to increase work efficiency and build an infrastructure for data sharing.

Channel-type lining board(CLB) is a welded steel structure used in the field of open cut subway excavation and building basement construction. Lining board is generally installed at the underground environment which is exposed to corrosion factors such as humidity, temperature and corrosive gases. This study evaluates reusability of the corroded lining board by experimental and analytical method. Static loading tests were performed to know serviceability of corroded CLB after checking thickness loss of the used CLB parts. Strain of the plates and middle point deflection was measured simultaneously. According to experimental test results and comparison with numerical analysis, the thickness loss of the plates by corrosion makes more vertical displacements and stresses in members under the DB vehicle load considering impact factor. As a result, this paper is proposed a way to evaluate used and corroded CLB by checking the plates thickness and it makes construction engineers easy to know optimal time to replace their old CLBs with new one.

The purpose of this paper Is to describe the matters to plan the best information systems in Korean old books. It analyzes: i) a range of definition of old books, ii) its characteristics and current state of processing the old documents, iii) the scope of automation and building up the library institution, iv) the construction of Korean old books Information systems, v) its case study, and vi) the evaluation and vision of system. The old document information system have been organized on the basis of library networks systems with the National Central Library as leader, its implemented system has the subsystem such as cataloging system, annotation system, full-text or image-based system, and retrieval system. In case study, it is suggested two examples which has been built in the National Central Library and Sung Kyun Kwan university. finally, it provides the evaluation criteria and vision for the library which designs the old document information systems.

This study is to explore floor impact sound and sound insulation of reinforced concrete structure with void-deck slab system which combines polystyrene void foam and T-shaped steel deck plate. A void-deck slab system can effectively reduce the amount of concrete used and hence the mass of a reinforced concrete slab. Also void slab system has dynamically favorable for bending. Three-bay 2-story building was constructed as a mock up test specimen using void-deck slab system and floor impact sound was measured to valuate sound insulation performance. Light weight floor impact and heavy weight floor impact were investigated. Light weight floor impact pressure levels were 32dB, 28dB, and 29db at representative locations which are $1^{st}$ level in the floor impact sound insulation performance grading system. The heavy-weight floor impact pressure levels were 44dB, 45dB, and 43dB at representative locations which are $2^{nd}$ level in the floor impact sound insulation performance grading system. Therefore void-deck slab system can be used in public housing apartment building in terms of not only effectively reduced construction materials but also floor impact sound insulation.

Currently, 54 kinds of digital maps are provided by National Geographic Information Clearinghouse and the majority of those maps are based on aerial photographs or satellite image. The digital maps which symbolize and simplifies the topography and objects from ortho-photos does not reflect the objects 'shapes and facilities' changes. Especially, underground structures and complex building shapes are not correctly identifies by ortho-photos. Furthermore, the 1/1,000 and 1/500-1/2,500 maps for urban area produced by some local government or public organizations have detailed information with high precision, it is not easy to update the information due to the frequent changes of structures in the city. Although some efforts to solve this problem such as conducting field survey and shorten the survey period were tried, it is not the fundamental solution due to the high cost. Therefore, in this study, a realtime renewal and update of digital map using general survey are suggested. By assigning absolute coordinates to the general survey products and matching with digital maps, it is possible to update the digital map economically and rapidly. In addition, it is suggested that the construction of DB for general survey and sharing among survey companies to solve the duplicated survey.

E-mail, one of the oldest services in internet becomes very important and essential way to communicate with development of internet. Due to E-mail has a property which is not complete for security, sometimes it is used for purpose of commercial or bad things, therefore it becomes the latest problem to keep off a Spam-mail and commercial advertising E-mail, many ways to keep off were perposed for it. In this paper, I explained how to sort and keep off these Spam-mail and commercial advertising E-mail with three way, prevention by server level, prevention by construction of network level, prevention by client level. we designed a prevention system for Spam-mail and implemented it by Visual Basic.

The purpose of this study is to construct an Environment Database Management System (EDMS) for the Saemangeum watershed based on the linkage of Water Quality Model, i.e. QUALKO and WASP model, and GIS database to estimate water quality effectively in this area. There are two major river systems on this study area, the Mangyeong and the Dongjin rivers. Input data are automatically generated through the calculation of the pollutant loading and inflow concentration from the point and non-point sources. The developed system is composed of three different phases, such as pre-process, model performance and post-process. The Model performance is supported by the database at pre-process phase and model performance results were shown in the graphs and attribution data at post-process phase. The measured data from the Mangyeong and the Dongjin rivers are used to evaluate the applicability of EDMS. The EDMS shows higher reliability, and it is expected to contribute to the effective management and improvement of water quality modeling in the Saemangeum watershed since the system reduces complications of using a model in DOS operating environment and increases the accuracy of water quality analysis.

Benchmarking is a process used in a lot of companies and public institutions because it is considered to be a practical tool for management innovation. However, it is hard to find out the development of systematic methods and applied cases for benchmarking on information services environment. This study tried to apply the benchmarking process to information distribution environment. This study examined the basic definition and standard process of benchmarking, and then conducted benchmarking plan to innovate tasks of database construction for information services at KISTI.

Building the Public Appraisal Information System(PAIS) has been a critical issue because real estate valuation process depends on the various information and analysis. However, there has been little research in this area. As a result, there is not any comprehensive plan for the PAIS constructed by the MOCT(Ministry of Construction and Transportation), and its database quality has various Problems. Therefore, this paper investigated the database of the public appraisal information system and suggested development strategies as follow: preparing a comprehensive plan for data collection, establishment of data management standards, additional collection of the attribute and spatial data, linkage PAIS and other information system.
