As the use of digital devices is becoming more commonplace, digital forensics techniques recover data to collect physical evidence during the investigation. Among them, the file forensics technique recovers deleted files, therefore, it can recover the database by recovering all files which compose the database itself. However, if the record is deleted from the database, the modified record contents will not be restored even if the file is recovered. For this reason, the database forensics technique is required to recover deleted records. Database forensics obtains metadata from database configuration files and recovers deleted records from data files. However, record recovery is difficult if database metadata such as block size cannot be obtained from the database. In this paper, we propose three methods for obtaining block size, which is database metadata. The first method uses the maximum size of free space in the block, and the second method uses the location where the block appears. The third method improves the second method to find the block size faster. The experimental results show that three methods can correctly find the block size of three DBMSes.

The early history of foreign Protestant missionaries in Korea has begun in the late 19th century, when they came to work as professionals such as teachers, medical doctors, etc. as the nation opened its door to western culture with the fall of national isolationism. Their records are considered crucial resources that enable us to shed new light on modern Korean history, politics, economy and society beyond mere religious value. Despite the recognition of such historic value of early missionary resources, however, there has been serious lacking of a systematic attempt to develop policies and plans for making it easy to collect, preserve and access the resources. Up to date, the records of early Protestant missionaries, in diverse forms of mission reports, books, periodicals, personal diaries, letters and photos, are scattered around various places, including their home country churches, governments, libraries, museums, research institutes and homes. Therefore, this research aims at providing basic resources on the archival status of early Protestant missionaries in Korea, needed for developing a sustainable and systematic digital archive system, through the investigation of early foreign missionaries' resources and in-depth interviews of experts. The study covers the period of 1800s to 1910, that is from the beginning of Protestant missionaries entering into Korea until the start of the Japanese annexation in 1910.

The first Protestant medical missionary, Horace Allen, came to Korea in 1884 and built the first western-style hospital, Jaejungwon. John Heron, Oliver Avison and other foreign medical doctors soon followed. They established hospitals and medical schools, and, by treating patients and educating native doctors, they disseminated and developed modern medicine in Korea. At the same time, they wrote letters and reports to their sponsoring agencies, as well as family and friends, thereby leaving a vast body of literature that is scattered all over the world. Since the end of the 19th century, the records left by foreign medical missionaries have been valuable resources for the study of Korean history. While all types of records, such as diaries, memoirs, reports and travel logs, are available, these tend to be exaggerated or unverifiable because they are unilateral records. In contrast, letters can be verified because they are bilateral records between the recipient and the sender, and cannot be modified or altered according to changes in circumstances. Despite the academic value of these materials, however, there have been insufficient efforts to discover or identify these primary data sources, or to systematically organize them for scholars. This paper identified 49 archival collections from 29 institutions in North America. After analyzing their academic value, the paper will explore digital humanities options in utilizing the letters for future scholarship.

This paper reports the evaluation of six open-source software systems for participatory digital archives. This is an effort to create a digital platform for the social memory of No Gun Ri, which was first recognized in 1999 as a civilian massacre. The process of how it was reported and investigated is critical to understanding this brutal incident. In addition, the course of its cultural recovery has witnessed the reconstruction of the No Gun Ri memory. Thus, it is important to embrace the social memory around the massacre in these archives. In consideration of a virtual space for memory, this study takes the form of participatory archives to provide a mechanism in which anyone can share their memories. As a way to find a digital archives system for No Gun Ri, this study analyzed open-source software based on identified functions and requirements for participatory digital archives. Knowing the details of digital systems, this study discussed how contents for social memory can be stored and used in a digital system.

The existing EMR method placing computer servers in hospitals could expose patients' personal information to hospital officers and people for wrong purposes. In addition, if medical malpractice occurs, the possibility of distorting medical records might be higher because patients' medical records are stored in hospitals. This study provides an electronic medical record with a security system to solve patients' information disclosure. The electronic medical record system could be utilized as an important information when medical malpractice occurs. This system can provide higher security services certifying patients safely and efficiently as well as protecting patients' personal information.

The pre-existing medical treatment was done in person between doctors and patients. EMR (Electronic Medical Record) System computerizing medical history of patients has been proceed and has raised concerns in terms of violation of human right for private information. Which integrates "Identification information" containing patients' personal details as well as "Medical records" such as the medical history of patients and computerizes all the records processed in hospital. Therefore, all medical information should be protected from misuse and abuse since it is very important for every patient. Particularly the right to privacy of medical record for each patient should be surely secured. Medical record means what doctors put down during the medical examination of patients. In this paper, we applies fingerprint identification to EMR system login to raise the quality of personal identification when user access to EMR System. The system implemented in this paper consists of embedded module to carry out fingerprint identification, web server and web site. Existing carries out it in client. And the confidence of hospital service is improved because login is forbidden without fingerprint identification success.

Recently, the central administrative agency changed its business management system to cloud-based On-nara 2.0. To transfer and manage the records of the cloud business management system, the National Archives Service has developed and distributed a cloud-based records management system. It serves as an opportunity to maximize the benefits of cloud computing and redesign the records management to be more effective and efficient. The process and method of electronic record management can be transformed through digital technologies. First, we can change the transfer method for electronic records. When the business and the records management systems share the same cloud storage, it is possible to transfer the content files between the two systems without moving the contents files physically, thus copying only the metadata and reducing the cost and the risk of integrity damage. Second, the strategy for allocating storage space for contents can be conceived. Assuming that the cloud storage is shared by the business and the record management systems, it is advantageous to distinguish the storage location based on the retention period of the content files. Third, systems that access content files, such as records creation, records management, and information disclosure systems, can share the cloud storage and minimize the duplication of content files.

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.
