Application of Compressive Wood to the Activity of Making-Things 楊, 萍 ヤン, ピン Yang, Ping Yamabe, Kaori Ohsako, Yasuo 657 wood processing compressive wood hydrothermal characteristics making-things monozukuli This is a case study on the application of compressive wood by harnessing its hydrothermal characteristic to the activity of making-things (monozukuli) which could be organized in schools. Sugi (Cryptomeria japonica D. Don)sapwood was used to produce the samples of compressive wood. The density of sugi sapwood after oven-drying was 0.480 g/cm^3, and the compression ratio in the radial direction was set as two-thirds of its initial dimmension. To ascertain the effectiveness of the application of compressive wood to making-things, three trial examples were made to display the entropy elastisity of wood utilized in commpressive processing to the students in an elementary school of Kumamoto City. The students' interest and concern about compressive processing of wood by using its hydrothermal characteristics were investigated by conducting a questionnaire survey among 27 sixth graders. Based upon the feedback received from the students, it is revealed that they could understood the entropy elasticity of wood,the key mechanism of compressive processing, through displaying samples combined with an explanation by using a model of wood cells. Consequently, a very higher valuation and a keen interest in such an advanced technology of wood processing were acknowledged. Almost all of the students expressed their wills to be eager to enjoy this kind of making-things. departmental bulletin paper 熊本大学 2003-11-28 VoR application/pdf 熊本大学教育学部紀要 自然科学 52 7 11 0454-6148 AN10315071 https://kumadai.repo.nii.ac.jp/record/16894/files/KJ00000691882.pdf http://hdl.handle.net/2298/2428 https://kumadai.repo.nii.ac.jp/records/16894 eng
