kn-abstract=本研究の目的は，ヒノキ集成材で製作された木製品のにおいと，その製品に使用された板材を被験者が手びきのこぎりびきする際に生じるにおいとについて，測定機による検査と官能検査とで比較することである。被験者は大学生と中学生とした。測定機での検査では，ほとんどの被験者ののこぎりびきにおいて測定されたにおいの値が木製品のそれより大変大きかった。板材の切断に要する時間が短いほどにおいの値が大きかった。官能検査でにおいの強度と快・不快度を調べると，切断に要する時間が短いほどにおいの強度が大きくなり，においの強度が大きいと快度が大きくなった。のこぎりびき中に大学生が感じたにおいの強度は，木製品各部のそれより大きかった。ヒノキ集成材を手びきのこぎりびきして生じるにおいの強度の大きさが認識された。

kn-abstract=The purpose of this study was to measure each color of three sections of wood with instruments, and to examine whether there were differences between each color of three sections. The total number of tree species measured was 60, with the same number of conifers and broadleaf trees. A test piece, which was a cube with one side of 34 mm, was prepared for each tree species. End grain, edge grain, bark side and pith side of each test piece were flattened by a hand planer. Then, lightness L* and hue/saturation (a*, b*) in the L*a*b* color space were measured with a spectrophotometer. The results showed that the end grain had a lower L* compared to the other planes. The end grain was reddish and yellowish because it had a large a* and small b*. When chroma C* and hue angle h in the L*C*h color space were calculated from a* and b*, the end grain had a small dullness with less vividness because C* was smaller than the other planes. L*, a*, b*, C* and h on the other planes excluding the end grain were almost equal for each plane. Furthermore, it was found that the plane whose lightness L* had the strongest correlation with the density of the test piece was the end grain. Therefore, the correlation diagrams between the density, average of annual ring width, and L*of the end grain of each test piece were shown.
