The New Vacuum Solar Telescope (NVST) is a 1-meter vacuum solar telescope that aims to observe the fine structures of active regions on the Sun. The main tasks of the NVST are high resolution imaging and spectral observations, including the measurements of the solar magnetic field. The NVST has been collecting more than 20 million FITS files since it began routine observations in 2012 and produces maximum observational records of 120 thousand files in a day. Given the large amount of files, the effective archiving and retrieval of files becomes a critical and urgent problem. In this study, we implement a new data archiving system for the NVST based on the Fastbit Not Only Structured Query Language (NoSQL) database. Comparing to the relational database (i.e., MySQL; My Structured Query Language), the Fastbit database manifests distinctive advantages on indexing and querying performance. In a large scale database of 40 million records, the multi-field combined query response time of Fastbit database is about 15 times faster and fully meets the requirements of the NVST. Our slestudy brings a new idea for massive astronomical data archiving and would contribute to the design of data management systems for other astronomical telescopes.

In terms of archiving. an importance of the Web is more increasing. Since the Internet has been popularized. many archivists have made efforts to preserve informational. cultural. and evidential values of the Web. Information resources on the Web raise archival issues that are significantly different from issues of preservation for tangible materials, because they are based on unique characteristics of the Web. One of issues is about a technical aspect which is based on technical architecture of Web. Another important issue is related to legal problems including copyright, authenticity and so on. In this context. it is essential to understand technical and legal characteristics of the Web. A purpose of this article is to review technical and legal aspects of Web archiving and to find an agenda for development of Web archiving.

Hallyu pop-culture contents which has influenced the world has sufficient preservation value as a cultural asset. However, there is still a lack of awareness of long-term preservation of Hallyu pop-culture contents and digital archiving is not in full swing, too. We requires accurate understanding of the concept, characteristics, format, media, and relationship of contents for digital archiving of Hallyu pop-culture content. Thus, this study analyzed and organized the concept, characteristics, and preservation subject of Hallyu pop-culture contents, as basic study for digital archiving of Hallyu pop-culture contents. In addition, we investigated the current status of digital archives (systems/institutions) of Hallyu pop-culture contents and Hallyu pop-culture contents, and presented basic proposal based on the problem factors.

This study aims to analyze the features and problems of the Korea's national records archiving system established in 1999, as well as to suggest the countermeasures. First, in Korea, permanent records are archived by the administration, legislature and judicature separately. However, around the world there are very few cases where a national archives controls the records of the administration alone, whereupon there is the need to set up an integrated archiving system regarding the records of the administration, legislature and judicature. Second, in Korea, the records archiving system leans too much towards the centrally-controlled system, which is urgent to be solved. 'Record Management Act' stipulates that all the public records, including nonpermanent ones, shall be managed by National Archives, wherewith National Archives is overburdened. Hereat, it may be desirable for National Archives to manage very important records that deserve to be archived permanently and for Record Center to archive other records, which needs to be made into law.

This essay focused on mapping out the next archiving model during 15 years. This metaphorical 'JINGU PROJECT' is titled from Shinto relation in Japan rebuilding every 20 years. We need some kinds of self sustainable growth archiving model. It means that it's time to say about our archiving experiences in field for archiving technics and knowledges. We should know the fact that a few thousands archivists have been acting ih fields. Since 1999, we have tried to build up the best practices in public offices. So far, So good. However, we need another wing for better flying from now on. I believe in the power of silences in field because they will speak up their voices.

The importance of digital forensics in the cloud environment is increasing as businesses and individuals move their data from On-premise to the cloud. Cloud data can be stored on various devices, including mobile devices and desktops, and encompasses a variety of user behavior artifacts, such as information generated from linked accounts and cloud services. However, there are limitations in securing and analyzing digital evidence due to environmental constraints of the cloud, such as distributed storage of data and lack of artifact linkage. One solution to address this is archiving services, and Google's Takeout is prime example. In this paper, user behavior data is analyzed for cloud forensics based on archiving data and necessary items are selected from an investigation perspective. Additionally, we propose the process of analyzing selectively collected data based on time information and utilizing web-based visualization to meaningfully assess artifact associations and multi-behaviors. Through this, we aim to demonstrate the value of utilizing archiving data in response to the increasing significance of evidence collection for cloud data.

In this paper, we describe the configuration of the KITSAT-3 image data receiving, archiving, processing and distribution system in operation. Following the low-cost and software-based design concept, the whole system is composed of three PCs : two for data receiving, archiving and processing which provide a full dual-redundant configuration and one for image catalog browsing which can be accessed by public users. Except that receiving and archiving PCs have serial data ingest boards plugged in, they are configured by general peripherals. This basic and simple hardware configuration made it possible to show that a very low cost system can support a full ground operation for the utilization of high-resolution satellite image data.

Picture archiving and communications systems(PACS) for digital image distribution, archiving and transmission, represent the modern hospital. PACS is the medical image management system within a hospital, whereas teleradiology system is the medical image communication system between remote sites. PACS and teleradiology systems usually consists of mainly four parts such as image acquisition part, image storage and database part, Image communication network part, and image display workstation part. Among these components comprised In the PACS, workstations are the point of contact between a PACS and the radiologist or referring physician. Therefore, the acceptance of PACS is highly dependent on workstation functionality, performance and easy of use compared with the conventional film-based radiology. This paper describes overall configurations and some requirements of PACS and teleradiology.

IT 환경이 급속도로 발전해 가고 있다. 기업 내에서 생성 및 보관되는 데이터의 양은 시간이 흐름에 따라 급격히 증가하고 있으며, 기업의 의사결정에 중요한 데이터의 가치는 변화를 거듭한다. 데이터의 증가는 곧 그것을 관리하는 비용의 증가를 불러오고, 방대한 데이터 속에서 진정한 정보의 가치를 창출하는 것이 어려운 상황에 직면해 있다. 이러한 기업의 비즈니스 프로세스에 맞춰 효과적인 ILM(Information Lifecycle Management)의 구현은 반드시 필요하다. 본 연구는 데이터의 가치를 보다 효과적이며 비용 효율적으로 사용할 수 있는 ILM의 구현을 위해 Database 기반의 Archiving System 구축 방법론을 제시하고 이를 바탕으로 실제 ILM이 구현된 기업의 구축 효과 및 성능 평가를 통해 그 타당성에 대하여 연구하는 것을 그 목적으로 한다.
