Abstract

When a frame was made using Cornus sericea ‘Flaviamea’, this study was carried out to investigate the body moisture content, which is the physiological change that causes frame deformation and drying time that can be preserved for a long time. Ten experimental groups were divided into two groups A and B with five groups each, and dried for 48, 96, 144 and 192 h, respectively. During the drying time, the weight change was measured with a load cell and observed at one minute interval in a data history recorder. In the results of being recorded at intervals of 10 min, the weight of both groups A and B showed the same tendency by a certain amount of decrease over time. In the results of deriving cubic polynomial and correlation coefficient for weight change, the value of the correlation coefficient R2 was found to be equal to 1 or about 0.99. This suggests that the cubic polynomial is highly correlated with a small amount of hourly weight of Cornus sericea ‘Flaviamea’. Although studies on cubic polynomials will be needed in the future, this study proved that it could predict the amount of weight loss. In terms of the weight loss and moisture reduction rate of the two groups by four different drying periods, 48 h decreased by 32.5 g on average, 16.4%, 96 h decreased by 52.9 g on average, 25.7%, 144 h decreased by 66.5 g on average, 32.3% and 192 h decreased by 82.6 g and 38.2% on an average. In the results of observing drying time effective for retention by fabricating a rectangular frame, immediately after drying experiment by the non-dry treatment experimental group, and the four dry treatment experimental groups, the frame of the 192 h dry experimental group was 0.2° in the left front corner, 0.2° in the right corner up to 1, 440 h, with the three-dimensional space travel distance S=0, showing that no deformation was measured. When Cornus sericea ‘Flaviamea’ is dried for about 192 h in a typical living environment and used as a frame design work, it is believed that it makes it possible to display for a long time.
