  • With the advent of the fourth industrial revolution era, the use of drone has been progressing rapidly in various fields. Now the drones will be used extensively in the area of investigation. Until now the criminal photographs stayed in 2D digital images, it would be possible to reproduce not only 3D images but also make a crime scene with 3D printer. Firstly, the video images taken by the investigation agency using the drones are digital image evidence, and the requirements for securing the evidence capability are not different from the conditions for obtaining the proof of digital evidence. However, when the drones become a new area of scientific investigation, it is essential to systematize the authenticity of the images taken by the drones so that they can be used as evidence. In this paper, I propose a method to secure the evidence capability of digital images taken by drone.

  • Objectives: Several domestic search systems for research projects providing capabilities of searching and managing the research information based on metadata have been completed, although they cannot search projects for specific domains such as the Oriental Medicine field. Therefore, in this paper we propose an effective method for collecting and refining information of research projects in the oriental medicine field. We also design and implement a search management system based on the collected information. Methods: We chose three search elements and defined the collecting process for research projects. The collected information was refined to enhance the quality of results. Then, the search management system was implemented by Adobe Flex. Results: We were able to collect 1,688 research projects in the oriental medicine field. We also implemented the search management system, which provides the functionalities of search and management such as input, update, delete, spreadsheet import/export of R&D projects, user management and access control. Conclusions: The collected information and the search management system will be used in a project analysis system which will be constructed in the future. The project analysis system could help to analyze trends in oriental medicine research as well as construct a technical roadmap.

  • Recent disasters are a complex and growing trend. In order to effectively prepare for and respond to disasters that occur without notice, it is very important to use scientific information related to disaster and safety in addition to the standardized disaster safety information that is used. In this paper, we searched and selected major journals in the field of disaster & safety and conducted various network analysis studies using the classification scheme for development of integrated metadata for disaster & safety information developed through Disaster & Safety Information Sharing Platform R&D project as well as KSCD. Also, we have constructed and analyzed citation network, co-authorship network and keyword network through data identification and preprocessing of research paper contents. As a result of this study, based on the network constructed by information analysis unit, the network structure between core domestic and foreign journals, major research institutes, core keywords and individual information by disaster & safety type was identified in detail, and the analysis results were presented on a case-by-case basis.

  • The study aims to investigate the management status of fire services records of local government D in the metropolitan area. To achieve this, the study analyzed the data from 2013 to 2017 based on the production, preservation, and disposition processes of records. The findings are as follows: 1) unkept regulations to transfer the records, 2) a lack of understanding of archival objects, 3) reconsideration of the history management of the records appraisal committee, 4) and an on-site update of records. Therefore, this study suggested the following for an effective fire services records management: 1) training for the fire services records management, 2) proper budgeting for the records management, 3) and secured metadata for the history management of records.

  • A rapid development of semiconductors, sensors and mobile network technologies has enable that the embedded device includes high sensitivity sensors, wireless communication modules and a video processing module for vehicular environment, and many researchers have been actively studying the smart car technology combined on the high performance embedded devices. The vehicle is increased as the development of society, and the risk of accidents is increasing gradually. Thus, the advanced driver assistance system providing the vehicular status and the surrounding environment of the vehicle to the driver using various sensor data is actively studied. In this paper, we design and implement the smart vehicular camera device providing the V2X communication and gathering environment information. And we studied the method to create the metadata from a received video data and sensor data using video analysis algorithm. In addition, we invent S-ROI, D-ROI methods that set a region of interest in a video frame to improve calculation performance. We performed the performance evaluation for two ROI methods. As the result, we confirmed the video processing speed that S-ROI is 3.0 times and D-ROI is 4.8 times better than a full frame analysis.
