As the major research outcome, it is difficult for the university department to understand the housing preferences of international students, and to know the real picture after moving in. Although there is a certain demand of international students for private rental housing, management companies are reluctant to let properties to foreign residents, mainly because of concern over communication and credit. Therefore, it would be useful to establish a liaison organization that continuously engages and shares information among universities, international students, and management companies.

They have tori-doma (earthen floor), and the rooms are usually arranged in the order of mise, okatte (kitchen), and zashiki. In modern times, however, the kitchen is often built in the back. Looking at the distribution of typologies, we can see that while many traditional typologies remain in Nakamachi, modern ones are found in other areas. This analysis by architectural typology is an effective means for observing the transformation of urban spaces.

Under a static machining path of numerical controlled machining, when the machining path is completed successfully, the machining of the member is as accurate as the trajectory of the tool. However, it is difficult to confirm that the machining was performed accurately for a machining path that changes dynamically through feedback control. In addition, as the machined surface may have a texture peculiar to the blade, the machined surface cannot simply be compared with the designed shape. In this study, we will examine an achievement evaluation method for evaluating the accuracy of dynamic machining.

The position-posture estimation by image features has some problems such as missing materials and textures. To solve the problem of position-posture estimation, we employed Affine-SIFT and segmentation matching. By adopting these two methods, it is possible to estimate the position and orientation regardless of some missing materials and textures. In order to verify the effectiveness of our method, a wall and a corner of a traditional wooden building were created. By creating them, the effectiveness of our method is confirmed.
