  • The rock-carved seated Buddha of Unju temple of Hwasun, Jeonnam, the only Triad Buddha among the stone Buddhas of Unju temple, is currently designated as a tangible cultural property No. 275 of Jeollanam-do. The rock of the seated Triad Buddha bedrock is light-green andesitic tuff breccia that is composed of quartz and feldspar. The results of measurement of the whole rock magnetic susceptibility characteristics, the rock consists of a single sedimentary layer from top to bottom. The results of ultrasonic velocity measurement, show that the number of frequency of 1500~2000 m/s increased and the number of frequency of 2000~2500 m/s decreased in 2009 compared to 2015, and the measurement value for 2000 m/s or below was 87.5% in 2015, a 68.8% increase in comparison to that in 2009. Moreover, on the top, bottom, left side, and head areas of the Triad Buddha, a partial expanding tendency was observed in the range of low ultrasonic velocity. As weathering of the Triad Buddha occurs in the long term, on-going monitoring is required to ascertain the degree of change with time.

  • 세계 각국은 자국의 문화재를 보존하기 위해 많은 노력을 기울이고 있다. 디지털 복원 기술을 이용하여 문화재를 영구히 보존하려는 시스템 개발 또한 그 중 하나이다. 그러나 문화재는 유형의 물체뿐만 아니라 그에 얽힌 전설과 정신 또한 중요함에도 기존의 시스템들은 형태적인 복원에 치중한 것이 대부분이었다. 본 논문에서는 예술적 상상으로 가상현실 시스템을 이용해 문화콘텐츠 개발을 위한 예술기획 기법을 설명한다. 제안된 기법은 문화원형을 선정하고, 문화적, 예술적 분석과정을 거쳐, 그 결과를 가상현실 시스템에 적용한다. 기획된 내용은 문화콘텐츠 체험 시스템에 적용되었다. 예술기획 기법은 형태적인 측면에서의 문화재뿐만 아니라 그 동안 부재되었던 정신적인 측면 또한, 과제 삼아 문화재 복원의 진정한 의미를 가상현실 시스템에 담도록 하였다.

  • P-wave velocity was measured by the low frequency flaw detector in order to analyze the weathered state of a halo stone Buddha, Unju temple, Hwasun, Korea. By the results of laboratory tests on a fresh acidic tuff with the same rock of a halo stone Buddha, average absorption, average P-wave velocity, and average uniaxial compressive strength were 5.38%, 4,008 m/s, and 70.1 MPa, respectively. The results correspond to moderately strong rock. Average P-wave velocity of a halo stone Buddha measured by the low frequency flaw detector was 2,257 m/s in the left zone, 3,437 m/s in the right zone, and 2,802 m/s overall. Weathering index of a halo stone Buddha was 0.45 in the left zone, 0.21 in the right zone, and 0.33 overall. Comparing the results of a halo stone Buddha with them of laboratory tests, weathered state of a halo stone Buddha was analyzed highly weathered state in the left zone and moderately weathered state in the right zone. Furthermore, it suggests that the left zone of a halo stone Buddha was affected weathering more than the right one. Overall a halo stone Buddha corresponds to moderately weathered state of weathering degrees. In conclusion, it is considered that low frequency flaw detector may be applicable as a valuable method on analyzing the P-wave velocity of the stone cultural heritage with an irregular surface.

  • Recently, Interest in the restoration and 3D reconstruction of cultural properties due to the fire of Notre Dame Cathedral on April 15, 2019 has been focused once again after the 2008 Sungnyemun fire incident in South Korea. In particular, research to restore and reconstruct the actual measurement of cultural properties using LiDAR(Light Detection and ranging) and conventional surveying, which were previously used, using various 3D reconstruction technologies, is being actively conducted. This study acquires data using unmanned aerial imagery of UAV(Unmanned Aerial Vehicle), which has recently established itself as a core technology in the era of the 4th industrial revolution, and the existing CRP(Closed Range Photogrammetry) and terrestrial LiDAR scanning for the Recumbent Buddha of Unju Temple. Then, the 3D reconstruction was performed with three fusion models based on SfM(Structure-from-Motion), and the reproducibility and accuracy of the models were compared and analyzed. In addition, using the best fusion model among the three models, the relationship with the Polar Star(Polaris) was confirmed based on the real world coordinates of the Recumbent Buddha, which contains the astronomical history of Buddhism in the early 11th century Goryeo Dynasty. Through this study, not only the simple external 3D reconstruction of cultural properties, but also the method of reconstructing the historical evidence according to the type and shape of the cultural properties was sought by confirming the historical evidence of the cultural properties in terms of spatial information.
