  • The development of the Preservation Metadata: Implementation Strategies (PREMIS) aims to preserve practices beyond the limits of the Open Archival Information System (OAIS) conceptual framework; however, the examples and guidelines on connecting each metadata element to the actual data are unclear, making the design of preservation metadata in real digital archives difficult. Hence, this study investigates actual PREMIS 3.0-based preservation metadata management cases, preserves digital resources in various digital archive environments, and derives implications for the implementation and design of preservation metadata. Based on the analysis, the study proposes preservation metadata elements that can be considered when designing preservation metadata for digital archives according to PREMIS 3.0 application profile guidelines.

  • Format preserving encryption(FPE) performs encryption with preserving the size and format of plain-text. Therefore, it is possible to minimize the structural change of the database before and after the encryption. For example, when encrypting data such as credit card number or social security number, it is possible to maintain the existing database structure because FPE outputs the same form of cipher-text as plain-text. Currently, the National Institute of Standards and Technology (NIST) recommends FF1 and FF3 as standards for FPE. Recently, in Korea, FEA, which is a very efficient FPE algorithm, has been adopted as the standard of FPE. In this paper, we analyze FEA and measure the performance of FEA by optimizing it in various environments.

  • Mural tomb in Goa-ri(Goryeong) built in the 6th Century Gaya period investigated precisely by the scientific method. They were used to optical equipments for investigation and made a damage map according to the damaging types. The mortar layer was mostly exfoliated from the rest of the wall except for the burial chamber ceiling and corridor ceiling. Also painting layers rarely not observed. Most of the paintings were damaged except lotus painting in burial chamber ceiling. Various damage types that exfoliation, earthen dirt, film coating were found in murals. Damage factors of mural were the porous characteristics of mortar layer and the movement of moisture in the murals. They were caused physical damage such as crack, exfoliation. It was getting worse and causing to secondary damage like earthen dirt, film coating.

  • The purpose of this study is to investigate the transformation of archival appraisal theories in the digital environment. It is clear that the archival appraisal in the degital information technology era, characterized by the mass production of data type records on the information infrastructure will be fundamentally different from before. As the meaning of selecting in appraisal will be reduced, the existing archival appraisal theories need to be reviewed again. We can expect the decentralization of appraising centered on the national archives, considering the social proliferation of digital information technology. Meanwhile, expertise in archival appraisal will also be changed to a new professional acceptance model for digital technology. Digital technology will give us opportunities for a paradigm shift that may be difficult to understand with existing thinking of archival appraisal.

A Study on the Facility Design for People with Disabilities that Considers the Preservation Environment of Castle Heritage - Focused on the Castle Heritage in England - (성곽문화재 보존환경을 고려한 장애인 편의시설 디자인에 관한 연구 - 영국 성곽문화재를 중심으로 -)

  • In order to set the direction of providing facility for the utilization of castle heritage, as well as to establish the method for securing access and determine installation criteria in consideration of preservation environment, an analysis was carried out on the cases of having secured access for people with disabilities in England for the advanced utilization of castle heritage. As the result of the analysis, the planning factors of the facility for people with disabilities in England for the utilization of castle heritage were deduced as follows: 1) The plan for facility was focused on the disabled using wheelchairs and visually impaired persons, rather than on services for hearing-impaired persons and people with learning disability. 2) As for audience movement line plan, regular route was used for audience movement line to lead them in a single direction. 3) As for the provision of prior access information, 3 stepwise access grades were established for the facility information plan of heritage. 4) As for information service by disability type, models were provided; and complementary explanation was provided by using text, drawing, picture, video and voice. 5) Rest spaces were secured where audience could look out upon castle heritage. For the utilization of castle heritage, it is necessary to develop planning factors of the facility design for people with disabilities according to its characteristics.

  • This study was focused on establishing the concepts of the instream flow to prevent the problems for the conceptual ambiguity and the difference in the instream flow estimation methods. The average drought flow is defined as the flow required to guarantee the minimum function of the river such as prevention of drying. The environmental control flow is defined as the flow required to control optimal river environment, the flow required for navigation, prevention of sea water-intrusion, protection of river management facilities, conservation of water Quality, fishing, prevention of river mouth closure, control of groundwater level, protection of animals and plants, and landscape. The average drought flow was obtained by flow duration analysis for the natural flows in the Han River at Indo-Bridge gaging station. When considering the 9 factors related to environment conservation, the conservation of water quality was proved to be most important. The pollutants for the river flows were estimated and the water qualities were forecasted. After comparing the water qualities in the future and water quality standards, there quired optimal dilution flow was estimated. The average drought flow and environmental control flow are all non-consumptive flows. Therefore larger flow between them, i.e., Max. (average drought flow, environmental control flow) can be the instream flow. The river management flow can be added to the flows for water utilization in the downstream. The results from this study are expected to be very helpful in the systematic river management on the other main rivers in Korea.

  • 박물관 수장고와 전시실 내의 유기물 문화재는 실내공기에 부유하고 있는 먼지와 곰팡이로 인해 생물적 피해를 받는다. 미생물로 인한 피해를 줄이기 위하여 박물관에서는 환경 조절법을 시행하거나 수장고와 전시실 내에 보존약제를 놓거나 또는 훈증 처리를 통한 방균 방제처리를 시행하고 있다. 미생물의 발생은 문화재 표면의 착색, 재질 분해, 변질 등을 야기한다. 본 연구는 위에 제시된 방법 외에 공기청정기를 이용하여 실내 부유 미생물 수를 줄여 유기물 문화재의 피해를 줄일 수 있는지를 알아보았다. 국립문화재연구소 내 생물과학실의 실험실 한 곳을 임의로 지정하여 공기청정기를 설치하기 전 곰팡이의 수를 측정하고, 공기청정기를 설치한 후의 곰팡이 변화를 4일 간격으로 측정하였다. 또한, 공기 중의 ???r성분 분석을 위하여 가스크로마토그래피(Gas Chromatography)를 이용하였다. 측정결과 곰팡이의 수는 대체적으로 감소하였으며, 채취한 곰팡이를 배양하여 동정을 실시하였다. 곰팡이 동정은 현미경을 통한 형태학적 분류와 ITS(Internal Transcribed Sequence)를 이용한 rDNA(Ribosomal DNA) PCR(Polymerase Chain Reaction)분석 두 가지 방법을 이용하여 동정하였다.

  • Excavated costumes included clothing that had been buried together with the corpse and shroud and unearthed during the excavation or the process transferring the tomb. The remains may easily get damaged under a different condition from the burial place, having gone through the deterioration process together with the corpse. In particular, since they are vulnerable to microbial propagation, suitable storage and conservation treatment immediately after excavation are required. Although more of them are unearthed in various parts of the country owing to exponential land development activities, they are rarely preserved properly due to a lack of appreciation of their value and a dearth of expert. Therefore, scientific examination and emergency preservation measures for the excavated costumes shall be described.
