This research aims to understand the precise character of relics based on literature search and material analysis of the jade excavated from the first buried place of King Jung-jo, and to assess the level of damage through non-destructive diagnosis. Furthermore, scientific conservation treatment was used to restore the original shape of the excavated jade. According to literature search, the excavated jade is known to be jasper, but material analysis showed that it was as a serpentine with the mineral composition of antigorite. Infrared thermography analysis to assess deterioration showed that the internal damage is the result of the interstices developed along the boundary surface of the obtained jade. For conservation treatment of the damaged area on the surface, the jade was filled with a mixture of plaster and glue, and covered with a mixture of acrylic paint and gloss medium for protection, and color was adjusted. 본 연구는 정조 초장지에서 출토된 옥에 대한 문헌조사와 재질분석을 통해 유물의 재질 특성을 밝히고 비파괴진단을 통해 출토 옥의 손상도를 평가하였다. 또한 과학적 보존처리를 실시하여 출토 옥의 원형을 복원하였다. 문헌조사 결과 출토 옥은 벽옥으로 알려졌으나 재질분석 결과, 출토 옥은 안티고라이트(Antigorite) 광물조성의 사문암으로 판단된다. 열화상분석 등 손상도 평가 결과 내부손상 부분은 포획물의 경계면을 따라 발달한 간극에 의한 것으로 나타난다. 표면손상 부분의 보존처리는 석고와 아교를 혼합하여 충전하였으며 보존처리용 아크릴물감과 그로스미디엄을 혼합한 후 색맞춤하였다.

석조문화재 균열부분과 표면 마무리를 위한 보존처리는 현재까지 에폭시수지에 다양한 충전제를 혼합하여 사용하게 된다. 장기적 보존을 위해 이와 같은 보존처리는 필요하다. 하지만 보존처리 된 54건에 대한 현장조사와 임상실험 결과 충전제 중 활석이 포함된 경우 표면변색과 균열 등 재 손상이 확인되었다. 현장조사는 수리보고서와 처리 담당자 인터뷰, 현미경조사, 현장에서 수습한 처리 시편의 ICP 분석을 병행하여 활석 사용여부를 확인하였다. 임상실험은 현장조사에서 확인된 활석에 의한 영향평가를 위해 촉진내후성시험 후 색차와 초음파측정을 실시하였으며 그 결과 활석이 포함된 시편에서의 물성저하가 두드러졌다. 따라서 향후 균열부분 보존처리는 활석의 사용은 자제하고 동질 석분만을 충전제로 선택하여 처리할 것을 제안한다. It is used for the epoxy resin, a mixture of various fillers conservation of cracks of the stone cultural heritage. Such as conservation treatment is need to for long-term conservation. However, field research and experiments on the conservation treatment results when included 54 cases of talc filler was confirmed that the damage, such as discoloration and cracks. The field research is talc was used to determine whether the reports and conservator interviews conducted, microscopy, ICP analysis of the samples collected from the field site. Experiments is color difference measurement and Ultrasonic measurement were arried out, and artificial weathering tests to investigate the effect of talc. As a result, lower the property of matter of the samples containing the talc. Therefore, we propose that the selection process is not allowed to use talc as the filler of stone powder filler cracks is conservation treatment.

Field experiments for Conservation damage on selected spots were carried out prior to direct conservation treatments for Bangudae Petroglyphs in Ulsan. It was found that there is a big difference in treatment effects according to the treatment technique and application rather than on the treatment material use. Based on the results of this study, a plan for the conservation treatment of Bangudae Petroglyphs will be suggested by providing new materials and application techniques for cracks, adhesive application and consolidation by conducting artificial weathering tests and continued monitoring. 울산 반구대 암각화는 1965년 축조된 사연댐으로 인해 매년 4~8개월간 침수와 노출을 반복하면서 훼손이 진행되고 있다. 이에 직접적 보존처리에 앞서 현장적용실험을 위한 사이트를 선정하여 각각의 손상을 제어할 수 있는 보존처리를 실시하였다. 모든 처리에는 비파괴조사를 실시하여 처리 전 후를 정량적으로 평가하였으며 모니터링을 위한 기초자료를 구축하였다. 실험 결과 처리재료보다 처리기술과 적용방법에 따라 처리효과에서 큰 차이를 보였다. 특히 에틸실리케이트 수지를 이용한 강화처리는 처리방법에 따라 초음파 속도 및 에코팁 경도상승이 확연히 구분된 결과를 도출하였다.

In this study we examined the effects of water extract of garlic on carbon tetrachloride-induced liver injury, and demonstrated increased beneficial enzyme and anti-oxidant activity as well as histopathological changes (by Hematoxylin-Eosin (H&E) staining, Trichrome staining, and TEM examination), and showed that the treatment was dose-dependent and safe. A total of 42 male Sprague-Dawley rats were divided equally (n=7) into six groups. To induce hepatotoxicity in these subjects, carbon tetrachloride diluted in an equal volume of olive oil was intraperitoneally administrated at 0.5 ml/kg (0.20 g/kg/day) once a day for five days. Water extract of Korean-grown garlic was administered via a stomach sonde once a day, 5 days a week, for a total of 4 weeks. Groups received 0.35 g/kg (E1), 0.70 g/kg (E2), or 1.40 g/kg (E3), with the dose adjusted for body weight. Administration of garlic extract resulted in positive physiological effects in terms of reduced oxidative stress and toxicity, and induced functional changes in the liver. Comparing the subject groups (E1, E2, E3) administered different doses of garlic extract, the importance of morphological analysis in further studies is emphasized, because morphological changes indicating hepatotoxicity could occur, even though beneficial enzyme activities were found to be elevated.

The purpose of this study is to evaluate the quality of life by the subjective indicators in local governments of a metropolitan area. There is increasing recognition that the quality of life is a very important issue and the local government should focus on improving it through delivering the appropriate public service. Then the results of public service need to be evaluated from the viewpoint of quality of life. This study suggests the measuring indicators in nine factors, and surveys how the residents in Daegu Metropolitan-city, Gyeongsan-city and Cheongdo-gun evaluate the level of conditions related with the quality of life in their administrative district. The results of the analysis summarize as follows: The residents' satisfaction in the general quality of life has a little improvement: Gyeongsan-city has the good condition of a healthy life, Cheongdo-gun has the good natural environment, and Daegu Metropolitan-city has the good conditions of education, social welfare, recreation and culture; the condition of a healthy life is a decisive factor on the quality of life: all residents' quality of life can be improved by linking their good conditions of life among local governments in a metropolitan area.

The paradigm shift in the global system has changed production-oriented industrial capitalism based on material values into consumption-oriented cultural capitalism based on human values. As a result, an industrial economy has developed into a cultural economy in cultural times, in which implementation of cultural policies focusing on globalization of regional cultures, major driving forces in value creation, is becoming more important. In particular, heritage resources in each region are valuable in that they establish regional identity, encourage self-esteem and love of hometown, and contribute to the improvement of regional competitiveness. Therefore, we need to make greater policy efforts to utilize each region's unique historic relics and cultural assets as resources useful for sustainable development. Most local governments recognize such demand of the times to some extent. However, because of lack of cultural capabilities at a global level, each region's cultural policies are confined within supplier-centered cultural events or festivals and there are still many limitations before regional cultures contribute to economic development. Against this backdrop, this study analyzes from the perspective of cultural development system why the Sill a cultural area, a major treasure-trove of the Korean culture, has recently faced a risk of losing its competitiveness. Based on that analysis, the study also explores desirable policy alternatives that Gyeongju city, a major local self-government in charge of the Silla area, should pursue in order to create high added-values by securing global-level cultural competitiveness. The Daegu-Gyeongbuk region, which has been regarded as a center for the Korean culture, includes the Sill a cultural area, Confucian cultural area and Gaya cultural area. Among them, this study focuses on the Silla cultural area, which boasts its abundant cultural assets from one thousand year history of the Silla kingdom. This study is confined only to the cultural development system, a subsystem that is the basis for the cultural recourses system. The contents of this study include sustainable regional development and cultural competitiveness, the relationship between culture and tourism, theoretical analysis on the cultural development system, investigation into examples of the world's historic and cultural cities, analysis on the current status of the cultural development system in the Silla cultural area, and the policy alternatives of the Silla heritage resources development for international competitive advantage. To conduct this study, I studied literatures and interviewed experts to theoretically examine cultural competitiveness and the policy standards of the cultural development system. Based on that, I established the analysis model for the cultural development system, and analyzed the current status of the Silla heritage resources development system by utilizing the positive and on-site data on the Silla cultural area. As a result of this study, considering comprehensively the relevance, desirability and feasibility, I suggest major development policy alternatives, through which the Silla heritage resources can acquire global competitiveness and universality. Those policies are systematically organized and classify by the elements of the cultural development system such as the approach and contents of heritage resources development, the distribution of heritage resources functions within the Silla cultural area, and the presentation or management of heritage resources and service facilities.
