The face of the Seated Stone Buddha ^{Korean Treasure No.84} of Sinboksa Templesite in Gangneung was contaminated with a glossy resin, spoiling its beauty. The contaminants covered the face, the forehead of the urna, to the bottom of the jaw. FT-IR analysis on a sample of the contaminants identified the substance as cyanoacrylate instant adhesive, which can normally be melted with acetone and removed with a swab. However, given that the surface of the statue was severely weathered from prolonged open-air exposure, alternative removal procedures were considered, to minimize the possibility of physical damage. After research, two removal procedures were utilized: one procedure involving poultices, which had been used to remove graffiti from the Samjeondobi Stele, and one procedure involving steam sterilization, which has been used to remove resin from pottery and porcelain. When both the poultices and steam sterilization were applied together, the resin was removed within twenty-four hours, without physical work using a swab.

This study is based on a scientific analysis of the production method of the wooden seated Bodhisattva statue from Gwaneumsa Temple in Wando, which is currently housed at Chonnam National University Museum. The purpose was to investigate the characteristics of the statue's production through an X-ray inspection of the wooden timbers that make up its base material, a composition analysis of the surface layers, and microscopic observation. The votive prayers found together with the statue allowed the precise dating of the artifact to the sixteenth century, during the Joseon Dynasty. The X-ray transmission identified the statue as being made using the "ilmokjo"(一木造) technique, which means that the entirety of the statue excluding the right hand was produced using a single block of wood. The specimen analysis of the naturally exfoliated surface layer revealed that the current surface was coated with brass to restore the original gilt layer. These research findings added an interesting case to the existing related research and reaffirmed the academic value of this statue.

고구려는 지리적인 조건으로 말미암아 삼국 가운데 가장 먼저 불교를 수용할 수 있었으며 5세기부터 7세기사이에 고구려의 불교문화가 백제, 신라와 고대 일본에 전해져 동아시아 전체에 보급되었다. 불교 전래 당시부터 고구려 왕실이 열성적으로 불교를 신봉한 일은 충분히 주목할 가치가 있는데, 왜냐하면 중앙 집권적 국가로 전환을 시도하던 때 마침 불교의 사회적 정치적 가치를 인식하게 되었기 때문이다. 불교와 왕권이 상호 관계를 강화하는 쪽으로 힘을 결집시켰는데, 왕실은 불교에 대해서 후한 지원을 아끼지 않았으며, 불교는 전륜성왕, 혹은 우주를 지배하는 자, 미륵 그리고 보살 등 모티브의 상징적 중요성을 통치자에게까지 확대시킴으로써 통치자의 지위를 신성시하는 이념적 기틀을 제공하였던 것이다. 이런 맥락에서 볼 때 불교를 받아들인 후에 세워진 비문들이 왕명 앞에 성(聖) 자를 붙여 왕의 지위를 신성화하는 의미를 나타내고 있다는 점은 우연의 일치가 아니다. 4세기말 국가 차원에서 불교를 수용한 고구려와 6세기초 법흥왕 당시의 신라는 시대적인 차이가 있으나, 국가 발전의 같은 단계에 서있었기 때문에 이 두 나라의 초기 불교 정책에 많은 유사점을 찾을 수 있다 고구려에서 거칠부와 더불어 신라로 넘어 온 혜량법사가 진흥왕 12년에 처음 개최된 백고좌강회는 《인왕경》에 입각한 것이며, 이 법회가 신라인의 사상적 통합과 진흥왕의 위업을 향상하는 데 기여하였다고 여겨진다. 그리고 진흥왕이 말년에 승복을 입고 법운이라는 법호를 택했는데 여기서 주목할만한 것은 법운(法雲)이 《십지경》에서 말하는 보살의 수행 최종 단계 그것에서 따온 것이며, 《십지경》은 이미 고구려에 익히 알려졌을 것이었다.신라 화랑이 미륵의 현현으로 여겨졌다 함은 일찍부터 지적되어 온 것입니다만 이 논문에서, 그것은 북중국에서 5·6세기경 유행한 그리고 소미륵으로 간주된 월광동자 (月光童子)신앙이 고구려를 통해 남하여 화랑의 사상적인 바탕이 됐다는 것으로 이해하였다. 그 증거로 《수라비구월광동자경》에 나타난 용어와 고대 한반도의 지명을 들 수 있는데 이 경은 고구려의 선인(仙人) 사상 및 신라의 화랑을 간접적으로 직결시킨다는 점도 염두 할 필요가 있다.

In this paper, Gilt-bronze Standing Avaolkiteshvara (National Treasure No. 293, M355) excavated at Gyuam-ri in Buyeo was observed with a microscope to identify the production technique applied to it. It was also analyzed with XRF and hard X-ray to identify the composition and the surface treatment techniques and casting method applied. In this statue, Avalokiteshvara is standing upright on a lotus pedestal. The lotus designs on the pedestal and those on the shawl flowing down on both sides of the statue are characteristic of Buddhist statues from the seventh century or later. The use of supports to affix the outer and inner molds and traces of injected cast were observed in the interior of the pedestal. The blisters on the arms and pedestal created during the bronze casting indicate the use of lost-wax casting, which was popularly employed for the production of mid- or small-sized gilt-bronze Buddhist statues in ancient times. The composition analysis identified a copper-tin-lead ternary alloy in the interior of the statue that was conventional used in the sixth and seventh centuries. It is likely that this simple alloy was used to facilitate casting and produce clearer expressions of designs and ornaments on the statue. Mercury (Hg) was detected on the surface of the statue, indicating the use of amalgam-plating with gold (Au) dissolved in mercury. This plating method is a common surface treatment technique used for small gilt-bronze statutes in ancient Korea.

Recently, thank to the popularization of light-weight drone through the significant developments in computer technologies as well as the advanced automated procedures in photogrammetry, Unmanned Aircraft Systems have led to a growing interest in industry as a whole. Documentation, maintenance, and restoration projects of large scaled cultural property would required accurate 3D phenomenon modeling and efficient visual inspection methods. The object of this study verify on the accuracies achieved of 3D phenomenon reconstruction as well as on the validity of the preservation, maintenance and restoration of large scaled cultural property by UAS photogrammetry. The test object is cltural heritage(treasure 1324) that is the rock-carved standing Bodhisattva in Soraesan Mountain, Siheung, documented in Goryeo Period(918-1392). This standing Bodhisattva has of particular interests since it's size is largest stone Buddha carved in a rock wall and is wearing a lotus shaped crown that is decorated with arabesque patterns. The positioning accuracy of UAS photogrammetry were compared with non-target total station survey results on the check points after creating 3D phenomenal models in real world coordinates system from photos, and also the quantified informations documented by Culture Heritage Administration were compared with UAS on the bodhisattva image of thin lines. Especially, tests the validity of UAS photogrammetry as a alternative method of visual inspection methods. In particular, we examined the effectiveness of the two techniques as well as the relative fluctuation of rock surface for about 2 years through superposition analysis of 3D points cloud models produced by both UAS image analysis and ground laser scanning techniques. Comparison studies and experimental results prove the accuracy and efficient of UAS photogrammetry in 3D phenomenon modeling, maintenance and restoration for various large-sized Cultural Heritage.
