과학기술의 급진적인 발달과 환경보존규제 강화로 자동차의 수명도 그렇지만 항공기의 수명이 20년에서 10년, 앞으로는 더 짧아질지도 모르는 일입니다 빨리 기종을 확정하여 실력을 유감없이 발휘하는 길만이 항공산업을 발전시키는 길이라고 생각됩니다 우리 항공산업의 발자취와 개발의 중요성을 재인식하고, 국민과 호흡을 같이하는 새시대에 걸맞는 발전전략 차원에서, 정부의 구체적인 지원정책을 위시한 자세한 홍보의 필요성과 함께 기종선정이 조속히 마무리 되어야 합니다

The objective of this research is to show the possibilities of emulation strategy in the long-term preservation for the digital components of Korean public agencies. First, this study analyzed four major emulation projects that were conducted in the world, such as CAMiLEON, KB, Planets and KEEP. Second, it compared the three different emulation approaches, such as device emulation, OS emulation and application emulation. Third, it searched all the digital components that one public agency produced during the last six years. Through the search, this study found out that the HWP and XLS format files comprised around 90% of the files. Fourth, it examined the functionalities of the formats, which may have been lost when the format was converted to PDF/A. Last, this study introduced the two prototype emulators for the National Archives of Korea. One is a type of OS emulator, while the other is a type of application emulator.

The purpose of this study is to present some basic information essential for planning long-term preservation of digital audio files, which have been collected through 'Cultural Archetypes Digitization Project' by the Korea Culture & Content Agency. Needs and limitations of digitization of audio resources for their long-term preservation, digital audio archiving models(OAIS Reference Model and AHDS Model), some technical principles for audio digitization and preservation, preservation metadata and storing media for digital audio files were discussed. Compliance to the requisites listed in Audit Checklist for the Certification of Trusted Digital Repositories of RLG & NARA was suggested. It was also recommended to review the appropriateness of collaborating on digital preservation project with other institutions.

The conservation and restoration of wetlands are essential tasks for the sustainable development of human society and the environment, providing vital benefits such as biodiversity maintenance, natural disaster mitigation, and climate change alleviation. This study aims to analyze the strategic interactions and interests among various stakeholders using game theory and to provide significant grounds for policy decisions related to wetland restoration and development. In this study, hypothetical scenarios were set up for three types of cities: large, medium, and small. Stakeholders such as governments, development companies, environmental groups, and local residents were identified. Strategic options for each stakeholder were developed, and a payoff matrix was established through discussions among wetland ecology experts. Subsequently, non-cooperative game theory was applied to analyze Nash equilibria and Pareto efficiency. In large cities, strategies of 'Wetland Conservation' and 'Eco-Friendly Development' were found beneficial for all stakeholders. In medium cities, various strategies were identified, while in small cities, 'Eco-Friendly Development' emerged as the optimal solution for all parties involved. The Pareto efficiency analysis revealed how the optimal solutions for wetland management could vary across different city types. The study highlighted the importance of wetland conservation, eco-friendly development, and wetland restoration projects for each city type. Accordingly, policymakers should establish regulations and incentives that harmonize environmental protection and urban development and consider programs that promote community participation. Understanding the roles and strategies of stakeholders and the advantages and disadvantages of each strategy is crucial for making more effective policy decisions.

Academic research libraries are seeking a long-term preservation plan for journals for cost-effective stewardship. The emergence of shared print archives has given the library community the opportunity to resolve the problem of the lack of library storage and build a collaborative long-term archiving plan for the print journals. The purpose of this study is to examine Western Regional Storage Trust(WEST), the largest print journal archiving program in North America, and identify their strategies for building a distributed, retrospective print repository service for journals. Based on the analysis, this article will discuss the development of new trends of collaborative library management in a digital age.

Assuring that the integrity of digital contents is reliably maintained is an important component of long-term digital preservation. The purpose of this study was to examine and analysis the best practices of digital preservation policy and provide the basis theory for establishing a preservation policy for maintaining the integrity of digital contents. In order to achieve the purpose of the study, we examined the digital archiving practices for maintaining the integrity of digital contents. Especially, we focused on the storage media and file formats, the media and format conversion, disaster prevention and recovery, management and handling, inspection and monitoring, and security policies.

In this paper we propose Fourier magnitudes based privacy preserving clustering on time-series data. The previous privacy-preserving method, called DFT coefficient method, has a critical problem in privacy-preservation itself since the original time-series data may be reconstructed from privacy-preserved data. In contrast, the proposed DFT magnitude method has an excellent characteristic that reconstructing the original data is almost impossible since it uses only DFT magnitudes except DFT phases. In this paper, we first explain why the reconstruction is easy in the DFT coefficient method, and why it is difficult in the DFT magnitude method. We then propose a notion of distance-order preservation which can be used both in estimating clustering accuracy and in selecting DFT magnitudes. Degree of distance-order preservation means how many time-series preserve their relative distance orders before and after privacy-preserving. Using this degree of distance-order preservation we present greedy strategies for selecting magnitudes in the DFT magnitude method. That is, those greedy strategies select DFT magnitudes to maximize the degree of distance-order preservation, and eventually we can achieve the relatively high clustering accuracy in the DFT magnitude method. Finally, we empirically show that the degree of distance-order preservation is an excellent measure that well reflects the clustering accuracy. In addition, experimental results show that our greedy strategies of the DFT magnitude method are comparable with the DFT coefficient method in the clustering accuracy. These results indicate that, compared with the DFT coefficient method, our DFT magnitude method provides the excellent degree of privacy-preservation as well as the comparable clustering accuracy.

The work environment that produces and preserves records is changing in the digital transformation era, going beyond the new technologies of the Fourth Industrial Revolution. The electronic records management strategy in the archives must be prepared according to the technology, policy, and environmental changes related to overall records management of the era. Based on this, the basic environment in which the public can access records can be created by preserving the value of records. This study analyzes the direction of changes and strategies of records management in the digital environment and the direction of electronic records management strategies of the National Archives & Records Administration (NARA) in the United States, the National Archives of Australia (NAA), and the National Archives of Korea (NAK). Based on the analysis, the study suggests policies, facilities, and personnel elements as the core of the national electronic records management strategy and direction in the digital era.
