Urbanism Places Exhibition 2018 was held at 55HIROBA of the Shinjuku Mitsui Building in September 2018. The central concept raised by the exhibition on urban-planning-based public spaces was “planning heritage as real place”. The exhibition consisted of 4 thematic programs, which had a common principle not to disturb day-to-day activities in the planning heritage place. On the other hand, the exhibition itself was expected to derive public space functions and possibilities. The visitors’ evaluation made clear challenges on the balance between the conceptual pursuit and the visitors’ satisfaction as well as the differences of the evaluation between experts and non-experts.

This paper clarifies the followings. (1) What impact do the two destinations that have won the Blue Flag Award in Japan expect from the authentication ? (2) Which standards of the various Blue Flag standards are effective and why? From Internet surveys on the development of Blue Flag authentication, we clarified that Blue Flag is an authentication that emphasizes social issues. In addition, our interview survey on two regions in Japan revealed that there are differences in the motivation for acquiring the Blue Flag Award and in the activities and in the contents the systems of activities by local residents.

The construction industry is a unique industry which the labor supply and demand rate of change is inevitable. Also the construction industry’s labor intensive is very depends on human power, so the labor supply and demand in accordance with a busy period and a slack period must be adjusted. This paper aims to organize the mechanism of construction workforce supply and demand, and make the problem manifest. Based on the literature survey, we will organize the mechanism of labor supply and demand. Then, the unknown points that emerged and current facts were clarified through a hearing survey to construction companies.

This study revealed how lay members of Catholic Takayubaru Church maintained its church building and restored it after the earthquake. The first generation of members, who migrated from Goto to Takayubaru as farmers, served together in maintenance of the church building as they were helping each other in all aspects of life. Fewer members of the second and third generations continued such service since the unity in livelihood decreased. A few members of the second generation chose to carry out maintenance and restoration because of their personal understanding of faith, which was strongly influenced by that of the first generation.

We study about the reconstruction age, architectural carving style of the main shrine of “AKAGI-Shrine” in Sakaihiratsuka Isesaki-City Gunma and the relationship between the main shrine of “AKAGI-Shrine” and the master carpenter “Masatoshi Mimura”. This thesis is based on historical materials related to reconstruction of the main shrine of “AKAGI-Shrine”.

We conducted field surveys and interviews about the mountain huts on Mt. Fuji which were built around Showa 30’s (1955-1964). Until then, building materials were transported by horses or human power and the member dimensions of columns and beams were limited. Still, partially though, we confirmed that these stone huts have the same form and construction as the Edo era. Specially, a floor plan with an earthen floor parallel to the mountain trail is the basic form of the stone huts on Mt. Fuji. Plural kinds of tephra are used in the right place for the stone huts.

Kawaguchi laboratory of the Institute of Industrial Science, University of Tokyo maintains design change books of the main gymnasium of the National Indoor Stadium. These materials are divided into 5 booklets and instruct design changes of various parts. Tange and Tsuboi completed the main gymnasium using the large roof of suspended structure and the seismic control technology never realized in Japan. As a result, a number of design changes were made at the construction site. This report aims to create a summary and lists of these changes of the main gymnasium of the National Indoor Stadium Main Stadium.

This paper aims to consider the spatial flexibility in the house called E.1027 by Eileen Gray. Based on her discourse, we analyzed the formal elements with spatial flexibility in terms of the room position, the types of the formal operation and the relationships with the building body. As a result, we found that Gray realized the formal elements with spatial flexibility in all rooms, using the five types of the formal operation: “pivoting”, “folding”, “sliding”, “stretching” and “removing”. In especially, the operation methods of “pivoting” and “folding” were applied not only to furniture and also the fittings.

This paper clarifies the following: First, the four art pieces in Maison de Pèlerins by Le Corbusier are edited photographic prints based on existing artworks. Second, the placement of the art pieces depicting the life of Christ within the Maison de Pèlerins is related to the building’s plan. The investigation from 2009 to 2018 identifies the original artworks upon which the highly deteriorated prints were based. During restoration works, the original artworks were digitalized and prints were recreated. This research helps to preserve the building for future use by providing the data to Fondation Le Corbusier and l’ A.O.N.D.H.

Collective network refers to the gathering of different layers of connections that each local shop owner brings to a shotengai. Through their own personal experience, the owners bring to their shops unique products with an added value to it. In this sense, a shotengai behave as a series of entrances to different networks that leads the customer to narratives that they cannot experience in large-scale retailers. This paper presents a methodology to understand the collective network of the shops applied in Shoin Jinja shotengai.

The church of San Francesco was revived by the latest seismic reinforcement technology because it is an important World Heritage site. In the restoration process, they have been reexamining past technologies and seismic retrofitting, and constantly searching for new technologies. Shape Memory Alloy Device and Shock Transmitters Unit with steel belt, Spring damper for cross arch are original technologies. The verification process and experimental data are made public, and consideration is given to the application to other historic buildings.

Low cost GNSS sensors were installed on old RC buildings at Hashima Island, Nagasaki, JAPAN to measure deteriorated state. A statistical population moving average method was applied to those GNSS data as residual deformation measurement technique and analyzed in chronological orders. And temperature related expansion and contraction deformation were found in those buildings indicating their elastic behavior. Furthermore, the data can be continuously recorded and transferred in harsh measurement environment.

Biofied building is a building system that provides safe, secure and comfortable space for residents using a robot. The robot acquires the motions and positions of residents. However, it is difficult to control the robot not to disturb the residents’ activities. The purpose of this research is to incorporate motion prediction in addition to motion recognition. Many of the conventional methods use RNN (Recurrent Neural Networks), which is difficult to implement due to the necessity of big data and large calculation cost. Thus, we aim to propose a simple motion prediction method using a human body model based on dynamics.

At precut fabrication sites for high-mix low-volume production, multi-axis machines are operated using a dedicated CAD/CAM that derives an operating path concurrently with detailed modeling. Because a CAD/CAM based workflow has complicated frontloading and data management issues, the authors developed a generic CAM that creates an operation path from a 3D geometry of a part. This paper reports a process path deriving method for a circular saw using 3D shape recognition based on PointNet. The proposed method classifies shape types and segments cut patterns for joints of parts represented as a point cloud. A validation experiment showed the joints are classified and segmented properly.

Using GPGPU, we developed a method to calculate the solid angle of landscape elements with an omnidirectional field of vision, via intersection detection. We confirmed that the processing speed was approximately 500 times faster than the processing speed achieved using a single CPU. Furthermore, the developed method was applied for the calculation of the omnidirectional green visibility of models with randomly arranged trees. Thus, the relationship between the shape and number of trees and the omnidirectional green visibility was analyzed statistically. These results can be considered as an index of the green visibility rate when planning the arrangement of trees.

This paper proposes a novel analytical model (BECK chart) to investigate how architecture education programs contribute to learning about the built environment. First the educational content of 67 AIA-supported architecture education programs for children and youth are categorized. Next the model is applied to visualize how these categories relate to the built environment. This analysis aims to contextualize the content of architecture education programs for children and youth in order to evaluate the ways in which these programs provide Built Environment Education content. The value of the model is also discussed.
