안동은 경북 북부지역의 중심도시로서 동으로 영양, 청송, 서에는 예천, 남으로는 의성, 북으로는 영주와 봉화에 맞닿아 있는 교통의 중심지이다. 빼어난 자연경관과 함께 고가옥 등 한옥으로만 이루어진 하회민속마을, 퇴계 이황 선생이 후학을 양성하던 도산서원, 현존 최고의 목조건물이 있는 봉정사 등 273점의 문화재를 보유하고 있는 문화의 도시이기도 하다. 그 가운데 하회마을은 조선시대에 지어진 건축물들이 고스란히 보존돼 그 가치가 높다. 안동 하회마을은 충남 외암리, 순천 낙안읍성 등과 함께 우리나라의 전통 가옥과 풍속을 잘 살펴볼수 있는 민속마을이다.

This research investigated and analyzed the structure and material feature of the wall behind the Buddha of main temple in An-dong Bongjeonsa through applying the natural scientific method, in order to closely examine its production technique. As a result of the research, the structural and material feature of the wall has been clarified and its production technique applied to the structure has been understood in a comprehensive sense. The target sample basically adopted the two-layer wall system, which showed a symmetric structure to the center made with the wooden material, and is estimated to follow the structural tendency of a general wall which is organized with the first layer, the midterm layer, and the painting wall layer. Each layer formed by the production procedure showed difference in the material and production method according to its characteristics and roles. And it was identified that, in general, the higher a layer lies, the finer grains it has. Combination of the main materials and the additives, used for the wall forming, was presumed to contribute to improving its durability and conservativeness. Also interaction between the materials generating the conservativeness and the producer's technical effect seemed to fortify solidity of the wall.

This study interpreted the chemicals of the pigments and the coloring techniques employed on Youngsan Ritual Ceremony Buddhist Painting through a nondestructive analysis method and a microscopic observation. Based on the interpretation, this study closely examined the chemical properties of the names of the coloring materials specified on the ceremonial writing of the Buddhist painting. It is estimated that lead white was used for the white pigments, orpiment and organic pigment for the yellow pigment, cinnabar/vermilion, minium, red ochre, and red dyes for the red pigments, malachite or atacamite for the green pigments, azurite and indigo for the blue pigments, and ink stick for the black pigments. The pigment names specified on the ceremonial writing are juhong, jungcheong, hayeop, whangdan, and whanggeum, and it was verified that juhong is cinnabar or vermilion, jungcheong is azurite, hayeop is malachite or atacamite, whangdan is minium, and whanggeum is a gold foil.

The physical, mechanical and chemical properties of old and new Korean red pine (Pinus densiflora) were analyzed. The old woods were from dismantled timbers of Bonjungsa temple. The crystallized resin in the latewood was observed by microscopic analysis. Also, reduction of specific gravity, occurrence of microscopic cleavage of tracheid was observed in the old wood. The angle of microscopic cleavage of tracheid is estimated with the same angle of micro-fibril angle of 52 layer. The bending, compression and shear strength of old world were decreased about 35-27% than those of new wood. Dynamic modulus of elasticity measured by ultrasonic nondestructive test has the tendency of reducing by the time elapse of the wood usage. Therefore, deterioration of wood could be measured by reduction of specific gravity and dynamic MOE. The static MOE and mechanical properties of old wood could be predictable by measuring dynamic MOE in the longitudinal direction. Extractives of the old wood in 1-% NaOH solution are larger quantity than new wood. Therefore the decay of the wood could be evaluated by analyzing the chemical compound, especially 1-% NaOH solution. The results of this research could be used for understanding and prediction of the changing properties with elapsing time of wood.
