    Bhaktapur is known as one of the historic cities of the World Heritage Site in Kathmandu Valley. The authors have been conducting research to clarify the formational process of urban blocks in old city of Bhaktapur with a focus on two perspectives―urban fabric and the exterior design of urban dwellings. As a result of that, two methods is shown for grasping the formational process. This paper use these methods to understand the process and confirm that the results match. Finally, it presents the standard method that is useful for grasping the urban formational process in other cities in Kathmandu Valley.

    The purpose of this paper is to clarify the characteristics of the greening space and the actual conditions of maintenance in the award-winning works of Okayama City’s award system. Most of the award-winning works that have green spaces had a function as an open space. The spatial characteristics of these works were organized in terms of scale, age, and spatial components. It became clear that even those works that were highly evaluated hasn’t been maintained and that the situation has been getting worse as the years passed.

    The 7-axis articulated robot can arbitrarily rotate the position of the elbow by changing the angle of the 7th axis. When a 7-axis articulated robot makes a detour, it is necessary to properly control both the position and orientation of the tool and the E-axis angle. In this study, we propose a deep reinforcement learning method for automatically generating detour paths including control of the 7th axis.

    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.

    In this paper, image features are used to realize the repositioning of logs in between processing. 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.

    Recently, the wild boar damage has been increasingly serious in “Bingo Sports Park”. To take effective measures, it is necessary to understand where the damage tends to be caused. This study aims at identifying the main factors on wild boar damage by using logistic regression analysis and creating the estimation map of wild boar damage based on the result. Results shows that the wild boars tend to cause more damage in areas with more natural land cover and closer to roads and valleys.

    In the previous paper, we carried out literature survey on damage in Osaka plain due to the 1927 Kita-Tango earthquake and clarified that severe damage and casualty were reported in spite of its long epicentral distance of more than 100km. Nine years after, this area was hit by the 1936 Kawachi-Yamato earthquake occurred at the border area of Osaka and Nara prefectures. In this paper literature survey on this earthquake was carried out. Earthquake damage including revealed building damage and casualties is described based on the published documents.
