Image analysis was applied to evaluate the colors of cotton fabrics dyed with natural and synthetic dyes. Color measurements of these fabrics were done with a commercially available color scanner and a colorimeter. The X, Y, Z, L*, a* and b* values of the CIE color system were obtained for each pixel (i,j) in the image by respective measurements and by appropriate transformation of the values. The colors of the fabrics were measured either vertically or horizontally with a scanner having 512 divisions for every 6.5 cm, with ca. 0.1mm spacing. Total values of L*, a* and b* for all pixels in the vertical direction for pixel position ( i ) in the horizontal direction (i=0~511) were SVi-L*, SVi-a*, and SVi-b*, respectively. Similarly, SHj-L*, SHj-a*, and SHj-b* were also obtained for all pixels in the horizontal direction for pixel position ( j ) in the vertical direction (j=0~511). The SVi-L* and SHj-L* values of fabrics dyed with natural dyes showed large degrees of variation, while those with synthetic dyes showed very small degrees of variation. The difference between the colors of the cotton fabrics dyed with natural and synthetic dyes were discussed in relation to the coefficient of variation.

The concern with new approaches to see housing and ‘living in housing’ from a diversity perspective has been growing. Even though our lifestyles and living environment are undergoing many changes, the situation with regard to housing and architecture remains static. There is a concrete way of implementing an approach to obtain more suitable living spaces by introducing the concept of the Biofication of Living Spaces.The first purpose of this study is to verify a hypothesis that students recognize their housing and living in housing from a diversified and creative perspective in their learning through the concept of Biofication of Living Spaces. The second purpose of the study is to clarify what teachers learned at different levels in schools, and how their teaching perspectives had been changed. The following are the results of the study: The students’ images of the Biofication of Living Spaces are divided into 12 to 14 main groups. The students’descriptions are not merely of what might be regarded as stereotypical housing, but include diversified aspects such as the relationship between housing and people . Teachers’ teaching perspectives of housing had changed.
