An image analysis on unsymmetrical structures and a geometric design of "Koto" bridge at "Tomo"

研究结果如下：1)对“Tome”地方历史文献的调查表明，它是一个与朝鲜建立国际友谊，日本传统“koto”音乐和战败者康复的历史场所。2)从福山市8个分区的地方心理形象角度进行分析，暗示“Tome”应该参与女性形象。3)另一种心理分析表明，“琴”（乐器）具有强烈的女性形象，其形象会与“Tome”的地方形象相吻合。4)另一种对圆形和正多边形形象的心理分析表明，圆形给人最女性化的形象，方形给人最男性化的形象。三角形一般会给人男性化的印象，而高度低于底部的三角形则会给人女性化的印象。(5)对日本年表进行相关分析和回归分析表明，日本历史“反对派-政治-经济-文化”4个周期进程的假设表明，日本历史进程的周期时间估计为150年，但目前模型的相关系数不太好。

The results of the study are as follows :1) An investigation of literature of the local history of "Tome" shows that it is a historic place of an international friendship with Korea, the traditional Japanese "koto" music and rehabilitation of defeated men of power.2) Eight sub-areas of Fukuyama City were analyzed in the aspect of the local psychological image implies that "Tome" should participate a feminine image.3) Another psychological analysis shows that "koto" (an musical instrument) has a strong feminine image and its image will agree with thelocal image of "Tome".4) Another psychological analysis of the image of circle and regular polygons shows that circle gives the most feminine image and square gives the most masculine image. Trianglegenerally gives masculine image but that with less altitude than base will give feminine image.5) Correlation and regression analyses of the Japanese chronological table show that the hypothesis of the 4 cycle progress of the Japanese history, opposition - politics-economics - culture, show that the cycle time of the progression is estimated to be 150 years but the correlation coefficient of the model is not so good at present.
