This study explores the development of a methodology for treating architectural design as a “resource” that can be shared with multiple others. By focusing on the design tool “MOKU-CHIN RECIPE,” this research will (1) identify the types of information that constitutes the unit of the “recipe,” (2) clarify how each type of information is actually utilized, and (3) clarify the role that MOKU-CHIN RECIPE plays as a shared resource.

In Japan, the Accounting Law has had a strong influence on public procurements including architect selection, and the proposal method has just begun to spread. However, its implementation has been supported by the personal efforts of the person in charge. In this paper, with the interview to the key person who has been struggling for good architect-selection and analyzed the process on practice. As a result, we confirmed the importance of the following three points: requirement-briefing, selection-committee, and creating opportunities for proposals. On the other hand, this know-how was based on his experience in many departments as a prefectural official.

The results of this study are summarized as follows. In the comparison of the teacher house and the trailer house, the trailer house as a trial house was chosen for the person who wanted to experience the emigration more than teacher housing. And the number of immigrants and dual habitation increased more than using teacher housing. When using as an emigration experience facility, the high flexibility of the installation of trailer house was effective for the region with sightseeing resources like Iijima town and trailer house can be also one option of the residence after the migration.

Urban areas in Hokkaido were constructed based on the “urban area maps”, allocating detailed dimensions and public facilities. By considering the content of plan changes, it may be possible to clarify the basic thinking regarding urban planning and design at that time. From the two urban areas, we confirmed that the information described in the design map had been realized with a high level of accuracy. As part of this, characterization of the roads was prioritized based on their width, and then later they were made uniform in terms of housing area.

Medellín’s urban regeneration, particularly “Social Urbanism” focusing on informal settlements in the 2000s, is regarded as one of the world’s most innovative cases. This study aims to provide a perspective by exploring the historical context and current status concerning Medellín’s experience for other developing cities trying to upgrade informal settlements. Through the study, the conclusion highlights the various activities in the 1990’s leading to Social Urbanism as well as the subsequent roles of the private sector and planning culture, and highly evaluate the participatory methodology and the scale-up to address the challenge of informal settlements.

This study examines the spatial practices of the facilities of South-Asian ethnic grocery shops, restaurants and prayer venues in order to clarify the food and prayer commonalities in Tokyo. The relationship between the concentration of the three facilities and the train stations of their location is termed as a “cluster”. Six clusters were found in Tokyo: NishiKasai, Okachimachi, Ikebukuro, ShinOkubo, Kamata and Jujo. The spatial practices of the facilities articulate their own identity as well as that of the clusters. By drawing comparisons between them, it is seen that the clusters affect the character of the urban setting of Tokyo.

The purpose of this study is to clarify the impact of the participation of tourism operators in the process of disaster prevention planning by local governments. Izu City’s new Disaster Prevention Plan not only incorporates multiple measures in association with disaster prevention for tourists but also invents the idea of “tourism resource development related to disaster prevention.” Additionally, it reveals that the opinions of tourism operators, which were concerned about the reputation damage from tsunami disaster, strongly influenced discussions through the planning process.

In the district of Kodokan and Mito Castle Ruins, integrated historical areas were realized by intensive public works from 2011 to 2020. This paper explores that the factor of realized intensive public works and the effects through documentary surveys and interview surveys. Through establishing the historic scenery maintenance and improvement plans, the organization involved fourteen divisions was created in Mito City. In the discussion of this organization, each division shares each work and policy plan for the first time. As a result, establishing this organization contributed to making new plans, receiving subsidies, creating the historical landscape, and improving safety.

This study clarified the significance and issues of cooperation between vacant house utilization and high school education which is targeting the comprehensive study conducted at Mikuni High School through effect verification of the actual situation of the vacant house utilization program in collaboration with the community and the practice of the initial stage.

Until now, utilization of vacant houses has not progressed. However, it was clarified that this program functions effectively as an initial stage to involve vacant house owners in community development from the viewpoints of community contribution to high school education and light burden experiment by short-term use.

The purpose of this study is to estimate the value of the conventional easy access system assuming Wheelchair users and the value of measures due to the spread of COVID-19 infection. This study conducted a questionnaire survey for the elderly in central Tokyo. As a result of the “Contingent Valuation Method,” the value of “installing an elevator” and “installing an escalator” and “disinfection of places that passengers can easily touch” was high. The elderly have stress when moving up and down at the station. Besides, they tend to worry about direct contact with their hands, such as train railings.

This study aims to evaluate the effect of the redevelopment of green roads and understand the residents’ needs. We conducted an observation survey at “Seseragi Park” at the time before the maintenance (July-September 2019) and after the maintenance (July-October 2020). Pedestrians tended to have dispersed traffic zones due to the widening of the garden road. However, the effect of setting up a “recommended route” for bicycles was low in the survey points. As a result of analysis with questioner survey on the entire GMS, we clarify a gap between the section with high utilization intensity.

In modern provincial cities, the phenomenon of the decline of shopping streets in front of railroad stations is occurring. The causes can be surmised to be internal factors such as problems related to union organization and individual problems. In the present paper, we examine the causes of the phenomenon of decline with a focus on the Shin-Sakae Shopping Street in Fukui City. The results that among the problems related to individuals, it can be concluded that the problems faced by business owners and landowners are the causes of the phenomenon of decline of shopping streets.

The Sustainable Development Goals (SDGs) was adopted by the United Nations, and the government in Japan has promoted SDGs for public and private sectors, even in district levels. It is necessary that each organization set quantitative goals to evaluate, however, lack of data-set is an issue. This paper deals with area-based SDGs goal setting and evaluation in Otemachi, Marunouchi and Yurakucho districts of Chiyoda-Ward. We firstly select one target from each 17 goals, and set quantitative target with LEED-City evaluation tools. As a result, how we develop data-set in the district for evaluation and selection of target are highly important.

In this study, external thermal insulation retrofitting was performed in four complexes of condominiums, constructed in 1971-72, located in a larger conglomerate of condominiums in Yokohama. Through interviews, we analyzed the process of renovation of each complex. The owners’ association of the first complex that underwent the renovation decided to keep a common room open for the visitors to see the effects of the renovation. The knowledge and experience of the preceding renovation were transmitted in this way to encourage the others to adopt the same method, and the following renovations took place as if in a chain reaction.

In this study, I drafted a super-long-term repair plan. As a result, I made it clear that: (1)Super-long-term repair plans cannot accurately calculate future payment amount for repair reserve. However, it is possible to predict when there will be a significant shortage of repair reserve fund. (2)A factor that will increase future repair costs is the life environment improvement work that is carried out in conjunction with extensive renovations. (3)For ultra-aged condominiums, it is important to announce in advance that the payment amount for repair reserve will increase by using super-long-term repair plans.

This paper describes the installation and evolution of the zushi (miniature shrine) and its shumidan (dais) in the main hall of the Fudōji temple in Shiga prefecture. By studying archives, it is believed that the zushi was built between late 15th century and early 16th century whilst the shumidan was built between mid and late 15th century. The zushi and shumidan is believed to have undergone modifications in 1599, 1888 and 1933. Through observation on restored parts, the original state of zushi and shumidan was deduced.

This paper introduces the drawing of the Leaf Tobacco Monopoly Bureau’s branch office buried in the TSUMAKI-Bunko Collection, as a new historical record. This paper suggests the following things. The accuracy and density of the depiction shown in the drawings are much higher than found in depictions which were previously known. The formats of both are also the same. The content of the drawings matches well with the existing remains in Kamogawa, Okayama Pref. There are some discrepancies between the drawings and the remains, which may be due to adjustments in the planning caused by variations in floor area.

This study clarifies the examination about neighborhood unit theory in the Architectural Institute of Japan Housing Issues Committee and the Japan Life Science Institute Architectural Subcommittee during World War II. The neighborhood unit theory introduced during the war was the prototype of postwar city planning standards.

In the construction of buildings at historic site, general construction methods may not be available because of historic preservation. Especially when using large diameter timber as structural material, it is necessary to not only deal with the restrictions of the surrounding environment but also devise the construction method. In the reconstruction work of Goromon Gate, the main gate of Kagoshima (Tsurumaru) Castle, the frame construction method was devised to deal with these technical issues. This report presents the contents and results.

The butai (chapel) and gohai (porch) of the main hall of Fudōji temple in Shiga prefecture was preserved during the restoration of the main hall in 1933. This paper describes the installation and evolution of the butai and gohai as an expansion of the main hall by studying the munafudas (ridgepole plagues) of the main hall and archives on the restoration of the main hall. It is believed that the butai and gohai were installed between the 1660s and 1750s and went through multiple modifications in 1770, 1809 and 1933.

Chusanren Building completed in 1963 was designed by Junzo Sakakura, of which design feature is floating volume covered with green tiles and warped eaves. It has experienced its renovation many times, and interestingly the owner itself has decided each renovation policy, without asking Sakakura. I summarized how it has been renovated and evolved, through architectural drawings, repair records, interviews, and confirmation of the current conditions. Consequently, it became clear that the parts of the building related to its design feature are mostly maintained, and only the other parts are functionally updated for its purpose from time to time.

Hanroku Yamaguchi’s “Plan for Osaka” is known to be a pioneering example of Japanese planning. This is the second in a series of papers confirming the contents of the accompanying text to Yamaguchi’s plan, “Explanation of the Plan for Osaka”. Part two deals Yamaguchi’s plan for the watercourse, park, harbor railroad station and an alternative plan for the main (first class) street. We point out that the watercourse plan typically reflects Yamaguchi’s concept of industrial development, and plans for the harbor railroad station and street alteration show a tight connection between Yamaguchi’s plan and the Osaka Harbor Construction Plan.

By using in a VR space, the same conditions as the physical space and the real space, we have confirmed the commonality between both physical and digital spaces.

It has become clear that through the digital space, by presenting either, a transformed space, different from reality or objects whose behavior is directed by informations, the human mental state of the test subject was affected.

The purpose of this study is to establish an efficient method for investigating the damage state of concrete. To achieve this purpose, a basic study on the measurement method of concrete crack width using high-resolution photographs was conducted on a damaged RC column specimen. We then examined the effect of shutter speed, which makes the difference in the light intensity that affects image quality. For cracks with a visual measurement value of 0.30mm or more, the average accuracy of the image measurement value was 1.13, which was generally good.

A processing machine is manipulated by a sequence of tool paths. The sequence includes individual processing paths that form material and detour paths that connect processing paths. Detour path generation is a problematic task similar to individual processing path generation when processing machines are applied for high-mix low-volume production.

This paper reports a detour path generation technique using deep reinforcement learning. A detour path is automatically derived from a pair of processing paths using the proposed technique. A test using an actual machine showed that the machine was appropriately manipulated by the derived detour paths.

The conventional workflow for producing wooden parts requires the wood workpiece to be firmly secured in the position predetermined by a processing path generation step. As a result, it is difficult to process curved raw wood pieces using machines.

To overcome this difficulty, we developed a single-shot posture estimation technique using pre-reconstructed 3D points and features, as well as a processing path transformation technique that adjusts the path according to the actual posture of the fixed workpiece. A curved beam named “taiko bari” was processed and subsequently tested. The results demonstrated that the proposed techniques are suitable for practical applications.

Following a static path, pre-calculated as the trajectory of the tool, cannot reflect potential changing states during the machining process. Therefore, adjusting to differences occurring in the environment between the assumed and actual conditions, such as variations in the physical properties of the material, is not possible. In this research, we dynamically change the tool path by monitoring the load applied to the tool during processing. Furthermore, applying our results to processing with a chisel demonstrates that parts can be machined appropriately by dynamic paths.

This study proposes effective teaching tools and architectural education methods of indoor thermal environments using 1/10 assembled house models for junior high school students. The thermal insulation experiment device and natural ventilation experiment device were developed as a supplementary tools. Architectural lectures concerning thermal insulation environments and natural ventilation were conducted for 117 junior high school students in Nagaoka during 2015, 2016 and 2019. Architectural education using these models and devices deepened students’ understanding about variations of indoor thermal comfort environments and form viewpoints of thermal comfort experiments for each wall type, and locations of window openings in house.

The COVID-19 pandemic since 2020, the lecture format of universities has had to undergo a significant change. In lectures on Building Construction, construction site tours are often provided. However, in the pandemic situation, it is impossible to be held in the same way as before. In this paper, we report examples of online site tours using two cameras with different view angles. Here, we used a web service that is intended for interactive communication. As a result, the promising potential of online site tours has been confirmed.

In this paper, to achieve the fast and detailed evaluation of seismic damage, the novel diagnostic imaging applied multiple image recognition techniques (Classification, Detection, Segmentation) in deep learning is proposed. Dataset from images generated by Generative Adversarial Network (GAN) brings the high-accurate recognition of the real damaged images. It is revealed that the diagnostic imaging can extract precisely the damaged area with minimum noise. Furthermore, the result of the damage extraction can calculate the seismic damage rate of the exterior wall.

Akita Prefecture, northern Japan, have more than ten large damaging earthquakes during the recent 120 years and the authors made literature surveys on major events. In this paper, the 1970 Southeastern Akita earthquake (M=6.2) was investigated. This local earthquake occurred at the boundary between Iwate prefecture and caused 6 injuries and damages to houses and infrastructures were reported. Through the literature surveys on reconnaissance reports and newspapers in both prefectures, detailed damages were clarified. We believe that the experience of this event can be utilized to future disaster prevention for not only this area but also the other areas.

This study aims to understand the behaviors assumed when a typhoon approaches the elderly living in Setagaya Ward. Using an official survey table called “My Timeline,” we asked the elderly to fill out their behavior according to alert level. As a result of text mining analysis of the free description, the behavior related to “meteorological information gathering” increased sharply at alert level 2. On the other hand, the behavior related to “emergency kit preparation” was about 40% at the time of alert level 1, but it tended to decrease after that.
