Web records is valuable information to preserve, because it can be used as a legal evidence about business or e-commerce of a public institution, but it is easily disappeared because of its volatile characteristic. Therefore, archival information package should be defined for long-term preservation. Web records can be stored in the archival information package for electronic records, because web records is a kind of electronic records. However, the NEO(NARS Encapsulation Object), the archival information package for electronic records in Korea, can't able to store web records, because it was developed without consideration of the characteristic of web records. In this paper, we define extended NEO based on the analysis of KoSurWeb and KoDeWeb, that archival information package for document of surface and deep web as well as the NEO. Web records can be preserved and utilized along with electronic records by using the extended NEO. Also it can be used for record and legal evudence by archiving web records of public institution about e-commerce.

Digital radiographic systems allow the implementation of a fully digital picture archiving and communication system (PACS), and provide the greater dynamic range of digital detectors with possible reduction of X-ray exposure to the patient. This article reviewed the basic physical principles of digital radiographic imaging system in dental clinics generally. Digital radiography can be divided into computed radiography (CR) and direct radiography (DR). CR systems acquire digital images using phosphor storage plates (PSP) with a separate image readout process. On the other hand, DR systems convert X-rays into electrical charges by means of a direct readout process. DR systems can be further divided into direct and indirect conversion systems depending on the type of X-ray conversion. While a direct conversion requires a photoconductor that converts X-ray photons into electrical charges directly, in an indirect conversion, lightsensitive sensors such as CCD or a flat-panel detector convert visible light, proportional to the incident X-ray energy by a scintillator, into electrical charges. Indirect conversion sensors using CCD or CMOS without lens-coupling are used in intraoral radiography. CR system using PSP is mainly used in extraoral radiographic system and a linear array CCD or CR sensors, in panoramic system. Currently, the digital radiographic system is an important subject in the dental field. Most studies reported that no significant difference in diagnostic performance was found between the digital and conventional systems. To accept advances in technology and utilize benefits provided by the systems, the continuous feedback between doctors and manufacturers is essential.

Recently, the processing and utilization of big data, which is generated by the spread of smartphone, SNS, and the internet of things, is emerging as a new growth engine of ICT field. However, in order to utilize such big data, De-identification of personal information should be done. De-identification removes identifying information from a data set so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information, thus it attempts to balance the contradictory goals of using and sharing personal information while protecting privacy. De-identified information has also been re-identified and has been controversial for the protection of personal information, but the number of instances where personal information such as big data is de-identified and processed is increasing. In addition, many de-identification guidelines have been introduced and a method for de-identification of personal information has been proposed. Therefore, in this study, we describe the big data de-identification process and follow-up management, and then compare and analyze de-identification methods. Finally we provide personal information protection issues and solutions.

Social Network Service (SNS) has gained great popularity. Recently, facebook has been used most active. Most of government ministries of Republic of Korea operates facebook. In the case of facebook, it takes advantages of possibilities to inform the direction of policy to aggregate opinions of people for issues. Information gained from facebook has a very important value to be reflected in the policy or to understand public opinions. Long-term storage for this information should be considered. In the case of overseas, tools for long-term storage of documentary facebook have recently been developed. However, it does not save all the data in facebook and ignores the principles for long-term storage. These tools are limited to a simple backup. Therefore, this study aims to investigate how to reproduce, store and collect facebook page records of the government ministries.

Purpose: This study was performed to evaluate the reliability of the identification of anatomical landmarks in panoramic and lateral cephalometric radiographs on a standard medical grade picture archiving communication system (PACS) monitor and a tablet computer (iPad 5). Materials and Methods: A total of 1000 radiographs, including 500 panoramic and 500 lateral cephalometric radiographs, were retrieved from the de-identified dataset of the archive of the Section of Oral and Maxillofacial Radiology of the University Of Connecticut School Of Dental Medicine. Major radiographic anatomical landmarks were independently reviewed by two examiners on both displays. The examiners initially reviewed ten panoramic and ten lateral cephalometric radiographs using each imaging system, in order to verify interoperator agreement in landmark identification. The images were scored on a four-point scale reflecting the diagnostic image quality and exposure level of the images. Results: Statistical analysis showed no significant difference between the two displays regarding the visibility and clarity of the landmarks in either the panoramic or cephalometric radiographs. Conclusion: Tablet computers can reliably show anatomical landmarks in panoramic and lateral cephalometric radiographs.

This study intends to design a curation system to support elementary and secondary schools for reusing and sharing instructional materials efficiently. It is proved through interviewing teachers at the chalkface that they utilize instructional materials, and there are some differences between elementary schools and secondary schools about the media for creating the instructional materials, and the purpose of using them. The functional requirements of curation system for reusing and sharing instructional materials are derived from questionnaires. The investigation of the existing curation systems was conducted to identify the strategies for policy, design, standard, and tools for effective operation of the digital curation system. The tasks and the functions of the curation system designed by reflecting the results of this study are as following. The tasks related to individual workspace include 'authentication', 'system configuration', 'registration' of created materials, 'material keeping' for the individual, and 'reusing (editing)'. The tasks related to sharing workspace contain 'receiving' for sharing, 'archiving' for accessing, 'peer evaluation', 'accessing' through the retrieval, and 'bulletin board'.

A large part of the vast amounts of information produced in the world is born digital, and comes in a wide variety of formats: text, database, audio, film, image. During the meeting of the Organization's Executive Board in May 2001, Member States agreed on the need for rapid action to safeguard digital heritage. The interest of UNESCO in this situation comes as no surprise. UNESCO exists in part to encourage and enable the preservation and enjoyment of the cultural, scientific and information heritage of the world's peoples. The growth of digital heritage and its vulnerability could hardly go unnoticed. Our societies have witnessed the end of the paradigm of the written archive, a paradigm that had developed over hundreds of years. Throughout the twentieth century new media have wisely and modestly joined this prestigious tradition. This paradigm has already been transformed, and the devices in place are unable to deal with the brutal advance of information technologies, and the quantitative inflation which they cause. This goes beyond those institutions specializing in the management of memory: a whole new regime of information will have to be constructed, and quickly, completely transforming old memory and archiving systems. If this shift does not take place, our societies will suffer irremediable damage in their collective social memory.

This study presents a contents model designed for business records that require long-term preservation. The contents model is based on the PREMIS(Preservation Metadata: Implementation Strategies) data model and the ISAD(G)(General International Standard Archival Description). The study selected the record collection of "the records of the overseas petroleum business and oil field development of A company located in B country." This collection requires permanent preservations by the nation and even beyond. It was attempted to establish the concepts of intellectual objects in the PREMIS data model to apply the PREMIS data model to the business records specifically. In other words, the study established the principles for differentiation of the classes in the record contents and the hierarchy structure, and the hierarchy model was developed for business records contents to derive the business records model based on those principles.
