In this paper, we propose a design of CCTV enlcosure record management system based on blockchain. Since CCTV video records are transferred to the control center through enclosure, it is very important to manage the enclosure to prevent modulation and damage of the video records. Recently, a smart enclosure monitoring system with real-time remote monitoring and opening and closing state management functions is used to manage CCTV enclosures, but there is a limitation to securing the safety of CCTV video records. The proposed system detect modulated record and recover the record through hash value comparison by distributed stored record in the blockchain. In addition, the integrity verification API is provided to ensure the integrity of enclosure record received by the management server. In order to verify the effectiveness of the system, the integrity verification accuracy and elapsed time were measured through experiments. As a result, the integrity of enclosure record (accuracy: 100%) was confirmed, and it was confirmed that the elapsed time for verification (average: 73 ms) did not affect monitoring.

'UAS flight recording system' is a system that is mounted on an unmanned aircraft system consisting of various components and records flight-related data. The data recorded by this system should be used for aviation accident and incident investigations to prevent similar accidents. In particular, for the category of UAS with high operating risk, safety devices close to that of manned aircraft are required, and it is urgent to develop flight recording systems reflecting the characteristics of the UAS to secure airworthiness. This paper highlights the need for UAS flight recording systems for aviation accident and incident investigations and seek a method to derive flight recording system parameters for 'Certified Category' with high operational risk. To this end, Inter-City UAM was used as a concrete use case, and the process of approaching system parameters was devised by assuming accident occurrences and hazards from mission profiles and scenarios. As a result of the study, it was confirmed that parameters could be derived through this process.

This study aims to propose the adoption of a business management system, as well as suggest the functions and development directions for public organizations, which are required to establish the record management and information disclosure system under Government 3.0, rapidly respond to the needs for strengthening the responsibilities for explanation, and improve work efficiency. Recently, some of the public organizations that introduced the record management and information disclosure system adopted the Electronic Document System, which focuses on the function of electronic approval, and developed a records classification scheme for the system. This study aims to review the case of A organization, which recently developed an in-house records management system and established information strategy planning to adopt a customized business management system after establishing a business reference model throughout the organization, and suggests the directions of the electronic record production system for public organizations.

The presidential records of the participatory government transferred to the Presidential Archives are the result of innovation in the record production system symbolized by the document management card of the e-jiwon system. Records reveal the policy-making process by documenting the decision-making process. This study identified the existing forms of records related to records management innovation produced by the Office of the Records Management Secretary at the Office of the President, and reorganized them into functions-activities-subjects-actions. Thematic record types help to systematically understand the evolution of the matter and the nature of the record. The characteristics of each record were identified by writing detailed information on the record. These attempts are meaningful in that they provide basic data for the evaluation and use of presidential records.

VLBI에서 관측 대역폭이 n배 증가될 경우 관측감도는 sqrt(n)만큼 향상되고, 이는 관측 연구 측면에서 기존에는 불가능하던 천체에 대한 연구 수행이 가능함을 의미한다. 관측 대역폭의 확대는 관측 데이터의 용량 증가를 의미하며 여기서 해당 데이터의 처리를 위한 초고속 데이터 기록시스템은 핵심적 역할을 한다. 이에 따라 현재 KVN에서는 미국 MIT Haystack 천문대에서 개발된 초고속 기록시스템인 Mark5B/B+와 Mark6를 운용 중에 있다. 하지만 이들 시스템의 경우 사실상 VLBI연구를 위한 목표로 특수 개발되었기에 유지 및 운영 측면에서 여러 불편이 있고, 성능에 있어서도 단일 스트림 기준으로 8Gbps를 넘지 못하는 한계를 안고 있다. 본 발표에서는 기존 시스템을 대체할 수 있는 기술로서 PCI 익스프레스 기반의 데이터 처리를 소개하고자 한다. 나아가 실제 관측 데이터에 대한 입출력 및 기존 시스템과의 성능 비교를 통해 광대역 관측 연구에 최적화된 기록 시스템을 제안하고자 한다.

The study designs and implements a metadata management system for archival and manuscripts control. It has two purposes. First purpose is to organize the collection that the Institution of Korean Church History holds by using the proposed metadata format. Second purpose is to suggest the model and framework for managing the collection. The proposed metadata is designed based on ISAD(G), USMARC AMC, EAD and Ebind, By using the proposed metadata, the collection management system, which allows an integrated retrieval, is implemented. In order to evaluate the efficiency of the proposed system as well as to gain the basic data for the improvement of the proposed system, a questionnaire survey through e-mail is conducted. The evaluation results will be utilized for improving and upgrading the proposed system, and the phrased implementation of applying the system to digital libraries is suggested.

Many problems of archival description in new environments can be solved by building archival authority databases. This study examines function and structure of archival authority records comparing with library authority records, and analyses the archival authority records in NARA system and Australian CRS System which accepts dynamic description process for archival records. Based on these investigations, some development directions for national archival authority database are recommended.

This study aims to propose management plans for 'Archive Village' that are operating in order to protect important private records and archives. Since 2008, Archive Villages from National Archives of Korea have had nearly 3,000 more records by 2014. However, many users have had difficulties to know the status of the recorded material, even less access to record's informations. This problem arising is that it is difficult to manage and use records. The purpose of this study is to propose a plan for the management of records, which is to realize the 'Computerization of records' official opinion, one of which was raised in the previous study. Because the project is facing the issue of 'human resources and costs', 'the burden of system construction'. This study is implemented records management system considering the problems noted above, utilizing AtoM (Access to Memory).

Records Management System(RMS) is a system for managing electronic records in records centers. However, RMS cannot content itself with the purpose of introduction and user demands. This is caused by lack of understanding the user's RMS and a review of the lack of detailed features. Therefore, the aim of this study reviews and evaluates a detailed accession function of RMS. Firstly, the study reviewed a detailed function of accession in RMS. Analysing the business processes that each function carried out, it defined functional requirements and investigated functional compliance as the check list which produced by the functional requirements definition. Finally, it surveyed and interviewed public records managers and analyzed the present situation of functional implementation of records accession function. Afterwards, improvement plans and implications were proposed through comparison of global-standard.

This study aims to develop a records management system for catholic churches that use open-source software to ensure systemic management and preservation of sacrament records, which accounts for the highest percentage among all records produced by catholic churches and holds great significance for them. To that end, the researcher analyzed catholic church regulations and reference materials, as well as the websites of open-source software. The researcher also interviewed members at the G Cathedral of the Catholic Archdiocese of Daegu, to examine the current status of records management at catholic churches. Based on the investigation, the researcher designed four layers of metadata and authority data that reflected the characteristics of the sacramental records. Then the design was experimentally implemented using AtoM, an open-source records management system.
