Abstract: PURPOSE: A method of predicting the rigidity of mixed kinds of timber using radiation is provided to enable the rigidity of all kinds of timber to be predicted since the rigidity of the timber is predicted through a deformed cross section, which includes the converted density of knot and the density of a good part. CONSTITUTION: A method of predicting the rigidity of mixed kinds of timber using radiation is as follows. Pictures are taken of the timber and the knot of the timber is detected(S210). The timber is divided into pixels and each knot picture is divided through the evaluation on the pixel connectivity of the knot(S220). A representative cross section is selected every divided knot(S230). The decrease ratio of the cross section every pixel of the timber, which includes the representative cross section of each knot, is calculated by considering neighboring knots(S240). The decrease ratio of the cross section of the timber, including the representative cross section, is converted into density(S250).

Abstract: PURPOSE: A cedar wood discoloration controlling method is provided to improve the timber weather ability of cedar wood by transferring terpenes, lignans and flavonoids to a splint wood. CONSTITUTION: A cedar wood discoloration controlling method comprises a step of thermal processing or light processing the surface of cedar wood including a black core to reduce the color difference of the cedar wood. The thermal processing is selected from a heat-drying, a vacuum drying, and a hot water treatment. The light processing is a UV processing. The hot water treatment is processed under the condition of the temperature less than 100 deg C.

Abstract: 본 발명은 방사선을 이용한 혼합수종 목재의 강도 예측 방법에 관한 것으로 목재를 방사선으로 촬영하여 옹이와 건전부를 구분하고, 옹이의 연결성 평가를 통해 옹이를 구분하고, 각 옹이별 대표단면을 선정한 후, 단면을 등가밀도로 환산하여 해당 수종에 대한 정보 없이도 모든 수종의 강도를 정확하게 예측할 수 있다. 본 발명에 의하면 수종 구분 없이 어떠한 수종일지라도 목재의 강도를 예측할 수 있으며, 구조용도로 이용할 수 있다.
