The Design of the Streets in the 21st Century from the Viewpoint of Clay Walls - A Suggestion about the Colors and the Looks of Modem Clay Walls by a scientific Method -

以下第一至第五项调查是在研究费用下进行的。使用荧光X射线分析装置（OURSTEX 100 FA）、数字显微镜（KEYENCE VH-8000）和分光测色仪（MINOLTA CM-2002）测量和分析粘土壁的颜色和着色剂。测量的地点如下：胜浦里丘的中胜院，明丰院，泽原市的加濑家，京都大德寺的玉麟院，札幌的八寿庵，京都的杉本家，京都的泽井家，犬山市的琼，大山崎町的妙家泰安，与琼有相同建筑设计的茶道室，京都岛原的住宫。另外，对粘土墙体的施工方法进行了分析，并对粘土墙体裂缝面积进行了测量.调查了14个传统建筑保护区的街道，并对建筑内外的泥墙颜色进行了调查.作者考虑了一项在佐原市的佐原和奈良柏原市的今井町的传统建筑保留区的恢复计划。在石田四郎博士的合作下，对被认为是“Juraku-tsuchi”的粘土进行了地质分析。海外考察：5-1作者对中国福建（南京和永定）保留地的土楼和街道进行了实地考察。5 -2作者对西班牙加泰罗尼亚的传统土楼进行了考察。

The following investigations from No. 1 to 5 were made at the research expenses.1. The colors and the coloring agents of the clay walls were measured and analyzed using a fluorescent X-ray analysis device (OURSTEX 100FA), a digital microscope (KEYENCE VH-8000) and a spectroscopic color-measuring instrument (MINOLTA CM-2002). The places of the measurements are as follows: Chushoin in Katsura-rikyu, Myohoin, Kase's house in Sawara-city, Gyokurinin in Daitokuji Temple in Kyoto, Hassou-an in Sapporo, Sugimoto's house in Kyoto, Sawai's house in Kyoto, Joan in Inuyama-city, Myoukian Taian in Ohyamazaki-cho, the tea-ceremony rooms which have the same architectural design as Joan, Sumiya in Kyoto Shimabara. In addition the authors tried to analyze the construction method of the clay walls, and measured the area of the cracks on the clay walls.2. The authors investigated the streets of the fourteen traditional buildings reservation areas and also investigated the colors of the clay walls outside and inside of the buildings.3. The authors considered a restoration plan of the traditional building reservation area in Sawara, Sawara-city, and Imai-cho, Kashihara-city, Nara.4. A geological analysis of the clay supposed to be 'Juraku-tsuchi' was made with the cooperation of Dr. Shiro Ishida.5. Overseas Investigations:5-1 The authors made a field survey of the Earth buildings with clay walls and the streets in the reservation area in Fujian, China (Nanjing and Yongding).5-2 The authors made an investigation on the traditional village with clay walls in Catalonia, Spain.
