This study aims to determine the research trends in archival preservation through keyword analysis, understand the current research status, and identify the research topics' changes over time. The degree and betweenness centrality analyses were conducted and visualized on 463 "archival preservation studies" articles published from 2000 to 2021 in various academic journals, using NetMiner 4.0. The collected research papers were divided into three time periods according to when they were published: the first period (2000-2007), the second period (2008-2014), and the third period (2015-2021). The subject keywords for the research papers on archival preservation in Korea that have influence and expandability are as follows. Across all periods, these were "electronic records" and "long-term preservation." In addition, if taken separately per period, the "OAIS reference model" and "electronic records" dominated the first and second periods, respectively, while the "records management standard table" and "long-term preservation" both dominated the third period. A conceptual framework and theory-oriented study for archival preservation, such as "digital preservation," "digitalization," and the "OAIS reference model," dominated the first period. During the second period, more research focused on procedures and practical applications related to conservation activities, such as "electronic record," "appraisal," and "DRAMBORA." In contrast, the majority of the research in the third period was on technical implementation according to the changes in the records management environment, such as "data set," "administrative information system," and "social media."

This study was carried out to investigate the general characteristics such as semen volume, pH, sperm motility and sperm concentration of the semen collected from Korean Jindo dogs by the mothod of Digital manipulation of penis, and the effect of temperature and preservation time on motility of fresh semen. Multiple ejaculates were collected from four male Korean Jindo dogs. The results obtained in this experiment were as follows : 1. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction and the small volume of third fraction from the ejaculate were 3.29ml, 6.30, 96.70% and 1.64$\times$108 cells/ml, respectively. 2. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the first fraction from the ejaculate were 1.16ml, 6.10, 6.67% and 5.07$\times$105cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction from the ejaculate were 2.30ml, 6.33, 97.66% and 1.92$\times$108cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the third fraction from the ejaculate were 3.24ml, 6.51, 93.33% and 3.13$\times$107cells/ml. 3. Motility of fresh semen during preservation were higher at 17$^{\circ}C$ than at 5$^{\circ}C$ or 36$^{\circ}C$. When preservation temeprature was 17$^{\circ}C$, motility were 95.75% at 1 h, 90.00% at 6 h, 84.25% at 12 h, 68.00% at 18 h, 36.25% at 24 h and 28.75% at 30 h, respectively.

This paper reviewed research trends in Digital Archiving and the OAIS Reference Model. Well renowned International Projects are also reviewed. InterPares, NEDLIB, CEDARS, CAMiLEON, PRISM are included. Several key functions of the OAIS Reference Model are presented and further research direction of digital preservation in Korea is also suggested.

Electronic environment affects archival community to a great extent. It redefines virtually every stage of archival management form creation to current and semi-current use, to appraisal, and to preservation of records. Faced with the problems caused by ever increasing electronic records, the community is forced to reconsider traditional concepts, approaches, methodologies, even the basic paradigm embedded in archival theory and practice. The present paper discusses the need to reexamine principles and techniques of archival management in the light of digital environment. It also urges archives and archival institutions, the archival profession, or the archival community at large, to participate in this critical enterprise. Success in this endeavor will, eventually, pave the road toward creating, organizing, providing access to, preserving reliably and authentically electronic records and designing proper system for the societal collective memory in recorded digital information.

Nowadays, the high quality of image is required with the demand for digital image processing devices is rapidly increasing. But image always damaged by many kinds of noises and it is necessary to remove noise and the denoising becomes one of the most important fields. In many cases image is corrupted by AWGN(additive white Gaussian noise). In this paper, we proposed an improved denoising algorithm with edge preservation. The proposed algorithm averages values processed by spatial weighted filter and self adaptive weighted filter. Then we add the value which is computed by the equation considering variance of mask and the estimated noise variance. Through the experience, the proposed filter performs well on noise suppression and edge preservation properties and improves the image visual quality.

Recently, industrialization of a country is accelerated and request of society infrastructure is raised so national land development is activity view. Accordingly, the search for a wide-ranging buried heritage do acted in large construction region. Because the buried heritage get buried in land that it is necessary to the precision search and research for a record and a preservation. Until now, Surveying techniques of a historic site have made status map, profile and cross section map through leveling survey, total-station survey and sketch of specialist. So, to solve problems existing relic survey or drawing making method have using digital camera these researches rapidly and economically obtain stereo image of object and present a technique that constructs 3D image model for digital photogrammetry method. Also, these researches construct 3D image model for record and preservation of a historic site through site test and in 3D and graphical express a historic site and support works that produce other maps if we need it. offer base data of GIS (Geographic Information System) to collect and analyze overall, information of a historic site.

In this study, the intellectual structure of Records Management & Archival Science in Korea was analyzed using document clustering, a widely used method of text mining, and document similarity network analysis. The data used in this study were 145 articles written on the subject of Records Management & Archival Science selected from five major representative journals in the field of Library & Information Science in Korea, published from 2001 to 2006. The results of cluster analysis show that the core subject areas are "electronic records management and digital Preservation," "records management policy and institution," "records description and catalogues." and "records management domain and education." The results of document analysis, which is more detailed than cluster analysis, show that "digital archiving," a specialized subject in digital preservation, plays a central role. The results of serial analysis, which proceeds according to a timeline, show the emergence of "archival services" as a new subject area.

Libraries, archives and museums share the common mission of collecting and providing access to cultural heritage for the use of both current and future generations. Although the evolution of these cultural heritage institutions have taken place separately, distinguishing publications, records and 3-dimensional objects, it is expected that the pervasive digital environment will not allow the distinction remain effective for long. The present study aims at exploring commonalities and differences of the cultural heritage institutions and illuminating the necessities and possibilities of collaboration among them.

Most of digital forensics tools focus on file analysis of allocated area on storage. So, there is a lack of recovery methods for deleted files by suspects or previously used files. To efficiently analyze deleted files, digital forensic tools depend on data recovery tools. These process not appropriate for quick and efficient responses the incident or integrity preservation. This paper suggests the framework for data recovery and analysis tools from digital forensics point of view and presents implementation results.
