The purpose of this article is to review the status of designation and preservation, management of national prehistoric sites and to suggest future applications. Prior to the discussion, the overall status of national prehistoric sites was reviewed. Specifically, the current status of designation, designated area, and distribution by region of national prehistoric sites according to the period and nature of the sites were examined in detail. Next, in order to understand the preservation and management of national prehistoric sites, I report the results of field trips to several sites, such as Geomdan-ri in Ulju, Songguk-ri in Buyeo, and Seoktaek-ri in Hongseong, and propose some measures for preservation, maintenance, and management of the remains. Finally, by referring to cases of US national historic sites such as protection, conservation, operation and management system and academic research project of cultural heritage, it is necessary to consider the need for a direction of the utilization that considers both socio-economic aspects as well as education and research on cultural heritage. The active use of cultural heritage can be a measure that leads to the continuous preservation and management of the sites, and ultimately will be a shortcut to increasing the value of national prehistoric sites.

Two-component epoxy resin is widely used in the cultural heritage restoration field. However according to mixing ratio of resin and hardener, curing property, mechanical strength and chemical structure differ which have possibility to effect the stability of cultural heritage. Result of questionnaire survey shows hands-on workers in the conservation field tend to mix the epoxy resin with his or her eye measurement when the using amount is small or mix additional hardener to shorten the pot life of epoxy resin. This research aims to analyze the curing property, mechanical strength and chemical structure of rapid curing type epoxy resin and medium curing type one depending on relative ratio of 0.25~4 of hardener to resin. When the amount of hardener was 0.5~2 times more than the resin, exothermic heat and curing speed were both increased. In case of included hardener to resin was lower than official ratio, mechanical strength (tensile shear strength, tensile strength and compressive strength) became higher along with active cross-linking bonding of the epoxy resin. Medium curing type epoxy relatively had lower exothermic heat and slower reaction during curing process. It was observed to be put to definite point of mechanical strength under lower content of hardener than official ratio. While, hardener ratio more than twice the resin slowed down the curing greatly and lowered the adhesion strength also. In conclusion, under the lower mixing rate of hardener than official ratio would show relatively fast reaction with similar mechanical strength. Over the official ratio on the other hand, material property drops rapidly. Accordingly, mixing ratio of epoxy resin is expected to be influential to the stability of cultural heritage.

The period from 1969 to 1999 is characterized as the rimes of radical reform in contemporary records management system of Korea. First, National archives was organized and it's function has been upgraded. Second, regulations of records management were established, revised, and integrated into a regulation of office management. Records disposition schedule was set up. The last, public records law was established. According to this law National archives was reorganized such as the national center of archival institutions. Principles of registration, classification and compilation, based on the principle of provenance, were established and the system of archivist was introduced.

This article was prepared for the purpose of reviewing maintenance plans and strategies for designating the celadon kiln site in Banam-ri, Gochang, a monument designated by the city and province as a historical site. Prior to the discussion, the high academic potential of this site, which is attracting attention as a main point of early celadon main point, was explained, and expectations for the future designation of the monument were reviewed. Next, the current status of preservation and maintenance plans of the celadon kiln site in Banam-ri, Gochang were examined. In particular, the current preservation situation was reviewed through an on-site survey on how the ruins, which have not been designated as a monument, should be maintained for historical designation in the future. Above all, it was argued that it was necessary to conduct excavation and literature surveys to clarify the characteristics of the ruins, investigate the surrounding areas, improve information facilities for visitors, and carry out promotion in connection with them. Finally, the definition of historical sites and the status of historical designation of ceramic kilns, along with the strategies necessary for designation, were presented. In particular, the examples of the existing historical designated celadon kiln site in Dotong-ri, Jinan, and Buncheong Kiln Site in Undae-ri, Goheung were reviewed, and three types of excavation surveys, literature surveys, and academic conferences were presented as the target directions for historical designation. The result of the excavation survey is the basis for suggesting that it has cultural property values with completeness, authenticity, and identity. The literature survey is the basis for supplementing the historical and cultural character of the remains that have not been revealed by excavation. The academic conference explained that it is an opportunity to understand the nature and value of cultural assets, such as the location of cultural assets, the status of relics, and events related to relics.

선미도등대의 등명기는 1940년에 제작되어 역사적인 가치가 뛰어난 등명기이나, 수은조식 회전 장치의 노후로 수은이 장기간 누출되어 근무자의 중금속 중독이 우려되므로 이를 회수하여 적법한 절차에 의하여 처리하고, 노후 된 회전장치 및 전구교환기, 균열이 발생한 프리즘 렌즈(보호대 포함)를 보수, 복원, 개량하여 등명기의 역사적인 가치를 보존함은 물론 항로표지로서의 기능 유지에 만전을 기하고자 선미도등대 등명기 정비사업을 실시하였다. 본 논문은 동 사업의 준비단계부터 최종준공까지의 추진방안 및 결과 등 주요사항들을 고찰하고 공유하여 향후 역사적인 등명기의 보존 및 개선 사업 추진에 있어 참고가 되고자 한다.
