This study seeks to find new strategies for the development of Tapgol Park and to identify Programs to promote this development. In addition, the study specifies the purpose and meaning of these efforts by revealing social aspects not apparent in the physical form of the site, and reading how these aspects influenced the development of Tapgol Park Because the focus of the study lies in reading cultural aspects of the site which have to be understood within the context of their social circumstances, the study drew materials from mass media such as newspapers and literary magazines, which best reflect these social aspects. Interpreting the over 100 you history of Tapgol Park in a cultural context, the study found a meaningful suggestion that such a small urban place located in a city forms a cultural identity in the course of communicating with its surrounding social situations. The change in the identity of Tapgol Park has been sensitive to changing social circumstances rather than the physical structure of the space. The original function of Tapgol Park as a traditional city park has gradually changed towards strengthening social functions, much like the character of an urban plaza. In the process of change the park developed a unique culture. This park culture, however, came not from the original design but from its close interactions with social circumstances changing over time. At the same time, the change in identity seen in Tapgol Park has not been fresh formed. It can be said that the inertia came into light with the potential powers under the place over the long history having been combined into the then social circumstances. In early 2002, the park re-opened, refurbished as one of the relics of the March 1st Movement. Investigating how cultural inertias that have been developing in various forms to date will change and be maintained in this new paradigm is an important assignment for researchers.

안개는 매우 작은 물방울이 대기 중에 떠다니는 현상으로 주변의 온도, 습도, 바람, 지형 등에 따라 안개의 형태나 발생 여부 등이 달라진다. 특히 안개는 수분을 함유하는 수원(水源) 근처에서 온습도 차이로 인해 발생하기 쉬우며, 오늘날 기후 변화는 안개 발생에 더욱 영향을 미칠 수 있다. 본 연구에서는 다양한 기후요인 중 안개가 문화재에 미치는 영향을 알아보고자 각 재질에 대해 옥외폭로 및 인공열화를 실시하였으며 지속적인 안개 발생으로 인한 재질의 손상정도를 예측하기 위해 색변화를 중심으로 회귀분석을 실시하였다. 금속 표준시편에 대한 옥외폭로 및 인공열화 결과, 표면 변화가 크게 발생하였으며 화견 및 단청류의 경우 표면상 열화된 모습은 관찰되었으나 색차의 경우 일정한 경향성은 확인되지 않았다. 안개 발생빈도에 따라 유의적인 색변화가 발생한 금속 표준시편을 대상으로 안개 발생빈도에 따른 색 변화 예측식을 작성하였으며, 실제 옥외폭로를 통한 색차값의 비교를 통해 색 변화 예측식의 적용 가능성을 확인하였다. 이를 바탕으로 향후 보다 종합적인 손상 예측식을 수립한다면 실제 현장에서 보존환경에 따른 재질의 손상도 예측이 가능할 것으로 기대된다.

본 연구는 문화재에 적용 가능한 다양한 훈증방법 중에서 에틸렌 옥사이드(Ethylene oxide)를 포함하는 훈증 약제가 문화재 재질에 미치는 영향을 평가하였다. 이를 위해 지류, 섬유, 금속, 안료 등 4종류의 시험편을 제작하고 훈증처리 전 후의 색상, 무게, 표면 변화, 그리고 지류와 섬유 시험편에 대한 적외선 분광분석을 실시하였다. 훈증처리는 약제를 처리하지 않은 무처리군을 대조군으로 하고 에틸렌 옥사이드 + $HFC_{134a}$, 에틸렌 옥사이드 + $CO_2$ 등 2종류의 훈증제 처리군을 실험군으로 하였다. 색차 측정 결과, 소다회를 이용하여 증해한 한지, 은, 면, 견, 모시, 황색 안료 등에서 색상 변화가 확인되었으며 특히, 은 시험편에서 평균 6.0 이상의 높은 색차 변화가 측정되었다. 그러나 은 시험편의 경우 훈증제를 처리하지 않은 무처리 시험편의 색차가 약제를 처리한 것보다 오히려 높게 나타나 훈증제 처리가 시험편의 색상 변화에 결정적인 영향을 미치지 않은 것으로 판단되나 훈증처리 시 주의가 요구된다. 무게 측정에서는 전체적으로 0~2% 정도의 변화가 나타났으며, 금속 시험편의 변화가 가장 적었고 지류 시험편의 변화가 가장 큰 것으로 나타났다. 시험편의 표면을 현미경으로 관찰한 결과, 일부 시험편 표면에서 색상 변화가 관찰되었으며, 은 시험편에서 가장 큰 변화가 확인되었다. 그러나 지류와 섬유 시험편을 대상으로 한 적외선 분광분석 결과에서 성분상 변화는 확인되지 않았다.

Plant-based cultural assets using straw and grass as household goods of our people's have been used as indispensable tools for practical living for a very long time. However, only a limited number of artifacts were unearthed so far due to tile fragility of the material. For this reason, research on plant-based cultural properties had close to no progress, and the appropriateness of the PEG method, high-grade alcohol method, alcohol--ether-resin method, and Paraloid B-72 used in preserving plant-based cultural properties has not been sufficiently investigated. Therefore, this study examined the weight change rate by applying the methods of Primal MC-76 and vacuum freeze-drying used mostly as a earth-layer hardening material among PEG and acrylic resin, which are applied widely for preservation of waterlogged archaeological wood, as a means to preserve plant-based cultural properties along with the examination of the subject material, and an experiment was also performed on moisture absorption. The findings as a result were, first, the plant-based material being studied was found to be Typha (Typha orientalis Presl). Secondly, the weight change experiment applying $PEG\#400$ and $PEG\#4000$ confirmed a steady increase of weight if PEG -2Step is used for treatment. Third, in preserving all subject materials with soil, treatment with $PEG\#4000$, Primal MC-76, and vacuum freeze-drying showed that tile vacuum freeze-drying method resulted in the largest or $20\%$ reduction in weight, while Primal MC-76 resulted in $18\%$ and $PEG\#4000$ in $8\%$ of weight reduction. It was concluded that, considering the stability of soil measurement, this came to be because resin permeation was carried out along with tile drying process. Fourth, the weight changes were found to be around $10\%$ in various humidity conditions after the preservation treatment. The greatest weight change rate was seen in the case of $PEG\#4000$, particularly having chemicals gush out in a high humidity (RH $84\%$ or higher) environment. In the case of Primal MC-76 and vacuum freeze-drying methods, $6\~8\%$ weight changes were detected, and the lowest weight change was found in the case of the vacuum freeze-drying method. Fifth, as for color changes after treatment, blackening occurred most strongly with $PEG\#4000$, while Primal MC-76 and vacuum freeze-drying manifested colors closest to dry straw or grass. However, the texture of straw was not very evident in the case of Primal MC-76, due to a glossy surface, but vacuum freeze-drying was found to offer tile best result in terms of texture. Putting together the results of the above experiments, vacuum freeze-drying presented after being treated with PEG2-Step the most stabilized changes in weight, while it offered the smallest change in color as well.

This study were performed thermal shock test for four kind of different rocks (Iksan granite, Namsan granite, Jeongseon marble, Yeongyang sandstone), and according to heating temperature($400^{\circ}C$, $600^{\circ}C$) on samples were investigated physical properties such as specify gravity, porosity, p-wave velocity. As a result, the tendency was appeared that porosity increased, and specific gravity and p-wave velocity decreased at a more higher temperature. But, the situation of change appeared characteristic according to temperature and rock types. In the case of Yeongyang sandstone, it appeared in especially porosity increasing at $400^{\circ}C$. The specific gravity was little change in the all the rock at $400^{\circ}C$ but the decreased at $600^{\circ}C$. Therefore the specific gravity in the temperature range is due to the relatively small impact on the change is expected. Porosity of the granite at $400^{\circ}C$ changes little. but marble in the rate of change is large. Conversely, the sandstone porosity decreased. At $600^{\circ}C$ increased porosity in all of rocks. particularly sandstone the smallest increase in porosity. Experiments showed that p-wave velocity measured through dry rocks was sensitive to quantify the thermal damage. The p-wave velocity of all rocks decreased with increasing temperature. In the relation between porosity and p-wave velocity, p-wave velocity decreased with increasing porosity. On the other hand, in case of Yeongyang sandstone p-wave velocity decreased with decreasing porosity. thus, development of microcracks more affects p-wave velocity than porosity. In this study, damage intensity was well explained with porosity and p-wave velocity values depending on temperature increase.

Cultural heritages are affected by various environmental factors. Main factors are temperature, humidity, light and indoor air pollutants such as ozone, nitrogen oxides. Especially humidity condition is very important. Low humidity condition can cause contraction and high humidity condition can lead to growth of microorganism. This study is conducted to appraise an applicability of the Humidity Indicator which is one of the simple method for humidity control. The Humidity Indicator shows the humidity conditions through color change. Therefore, photometer was used to correctly measure the color change of Humidity Indicator. As a result of lab test, Humidity Indicators was stabilized after one hour from en exposure in a certain humidity condition and the indicators indicated clear correlations between color changes of Humidity Indicators and humidity conditions. Some Humidity Indicators which had been selected through the lab tests were applied to preservation facilities of cultural heritages and the indicators indicated closed correlations with humidity conditions in indoor of facilities.

Paper is easily damaged by physical and chemical deterioration under several factors. Damaged paper cultural heritage is usually restored by Lining. A traditional method of Lining is attaching the lining paper behind the original paper cultural heritage using starch and water. It supports the weakened quality of paper. In Japan, paper cultural heritage is restored with "Washi" which is made from mixture of Paper mulberry and Japanese cedar. In the west, the lining paper made from Paper mulberry, which has extraordinary excellent conservativeness, is usually used as a restoration material for paper. But Japanese Washi has dominated the demand for restoration materials as the most preferred restoration paper, and most kinds of paper made from Paper mullbery have been called as 'Japanese paper'. Result showed that the strength of the Korean lining papers was generally higher than that of the Japanese ones. As a result from measuring the rate of dimensional change after water-immersion and drying, sample B of the Korean lining papers and sample E of the Japanese lining papers showed the highest stability.
