In the preservation of historical areas, past reconstructions serve as a medium to convey the meanings embodied by physical structures of the past to contemporary audiences. In the case of the Shikemichi area, the process of modernization of Nagoya Port has transformed its urban spatial status and structure, where the generation of open spaces marked by parking spaces has played a significant role. Against this backdrop, this paper aims to examine the potential impact of parking spaces on 5 types of past reconstruction in the process of redevelopment of the area’s historical identity, considering both historical and contemporary spatial structure.

The purpose of this report is to clarify the characteristics of external stairs that draw pedestrians’ eyes into the building and the value of stairs as a boundary space between the city and architecture. Through case studies and visual experiments, the followings were concluded:

1. Classification of stair construction methods

2. In general, external stairs have physiological and psychological attractiveness.

3. There are differences in attractiveness among configurations.

The purpose of this study is to demonstrate, through chronological analyses, how architects have been responding to the urban environment in the design of rental office buildings. Based on the review of design briefs of rental office buildings, urban-environment elements and architects’ design intentions are identified, tabulated, and analyzed chronologically in three ways: Firstly, urban-environment elements are classified into several types and their transitions are analyzed ; secondly, architects’ design intentions in response to the urban environment are classified into several groups and their transitions are analyzed; and thirdly, the relationship between the environmental elements and design intentions are analyzed.

This study aims to assess the applicability of multi-agent simulation for crowd control after large-scale events. It focuses on pedestrian pathways around a stadium in urban area. By utilizing real-world pedestrian flow data, we investigated the parameters essential for simulation and analyzed crowd control. Consequently, we identified critical simulation parameters, such as speed-density relationships and personal distance, which produced highly accurate results across different days. In terms of congestion control, we established an acceptable congestion range based on data and illustrated that averaging peak bottleneck flows effectively alleviates congestion using the simulation.

The study clarifies people’s perception of the daily connections between traditional country town and villages before the spread of the private car. We selected Yatsuo as a case study and analyzed the background of road development connecting the town and the villages. We revealed that the perceptions and their transitions varied depending on the village’s livelihoods and geographical conditions. This suggests that the bases of community and the surrounding areas that support them need to be designed with consideration as living spheres continue to change with these conditions.

This paper aims to identify theater agglomeration in Tokyo ward area based on the analysis of theater locations, and to clarify the characteristics of formation process in each agglomeration. First, using kernel density estimation for the 164 theaters located in the wards of Tokyo, eight theater districts were extracted. Second, in Yurakucho/Ginza and Ikebukuro, where the agglomeration of theaters tends to be particularly promoted, it was shown that the public and private sectors are working together to promote the agglomeration of theaters through the special zone, and to utilize public space around theaters.

We clarify the factors which promote civic activities through survey analysis using Otaru City as a case study, referring to previous studies on place attachment, civic pride and customer engagement. The methods used in this study and the main findings obtained as a result of the experiments are as follows:

(1) Results of factor analysis revealed that the factors promoting civic activities in Otaru City consist of four factors: “participation”, “enthusiasm”, “attachment”, and “identity”.

(2) Results of covariance structure analysis suggested that “participation” and “enthusiasm” increase “participation in community activities” and that “participation” and “participation in community activities” increase “leadership”.

This thesis presents an analysis of data from Japan's 2020 national census, estimating population and households in disaster-prone regions. These regions include flood-risk areas, tsunami-vulnerable zones, and sediment disaster areas. In Level 2 flood risk areas, around 50.4 million people reside, with nearly half in multi-unit housing and 28% living above flood depths. Approximately 8.2 million people inhabit tsunami-prone areas, and 5.3 million people live in sediment disaster hazard zones. Major cities in disaster-prone areas have a large population, but a significant portion of residents resides in multi-unit housing, which doesn't always correlate directly with higher disaster risks.

Consultation support in the Kumamoto earthquake can be categorized into (1) general consultation, (2) consultation based on on-site surveys, (3) information and consultation in packages, and (4) consultation aimed at housing reconstruction. While the Cabinet Office assumes item (4), a hearing survey reveals that it only includes the first three items. Measures to improve the cooperative structure efficiency include a diversion of relationships from normal times, utilization of personnel from outside the affected area, division of labor for consultation support, and a gradual increase in staff. For face to face consultations, function and distance from the affected area are important.

This study clarified the relationship between the weight and management methods of movable chairs. In installing movable chairs in public spaces, there is a risk of the chairs being blown away by the wind and a risk of malicious acts such as chairs being thrown, and to counter these risks, methods such as making the chairs heavier or removing them during storms or at night were observed. Moreover, in public spaces where lightweight chairs were installed, managers moved the chairs around depending on the time of day or during events to improve the comfort of the public space.

We analyzed the effects and components that citizens making a “temporary place” in a Park-PFI park. Activity managers that are citizens make social relation with the private sector of Park-PFI, and private sector has obtained permission to occupy the park annually for a “temporary place” in a Park-PFI system. Thereby, activity managers can set up a temporary place several days a week. This way, managers provide an environment that sellers easier to open stalls regarding days and costs. As a result, many stallholders use this place, and citizens visit and interact with each other.

We analyzed the characteristics of man-hours in construction site manager focused on job position and information media for communicate on management task, using the data obtained through self-reporting surveys.

As a result, project manager and deputy project manager tended to handle atypical tasks in construction planning, responses of architect and client, and cost management, while other staff tended to handle quality management. We classified information media into paper media and electronic media. Although we found progress of use electronic media in process management, we concluded there was still much room for improvement to electronic media of construction management.

Based on the expressed preference data of condominium buyers and inverse probability weight, this study examined the influence of their perceptions of the state of maintenance on internal reference prices. According to the findings, maintaining good maintenance conditions not only increases the aspiration prices of buyers, but it also increases the lower limit of price negotiations. Meanwhile, in the price judgment process, buyers who perceive that the state of maintenance and management is good tend to carefully search for properties. We also found that it is important to raise awareness regarding the appropriateness of purchase prices.

The author wishes to explore the development of the Japanese concept for reuse of removed parts from architectural cultural properties while focusing on the construction specifications. Initially by confirming the regulations, secondly, by making a list of the parts to be reused and analyzing it while separating the parts into 3 types; thirdly by identifying case studies from conservation project and analyzing them while separating the parts into 2 types; finally, by looking for changes, focusing on the period under the National Treasures Preservation Law.

This study compared the site, the spatial structures and the storehouse of Okura-syo owned by shogunate and domains, used for “Kaimai”, located on a port of an estuary in the Edo period. It clarified the properties which are found out of all Okura-syo, and categorized those Okura-syo. The Okura-syo used for “Kaimai” which cooperated with water transportation were formed with the efficiency of carrying and land utilization. On the other hand, it got the regional characteristics by the factors of an environment which are different between the Pacific side and the Japan Sea side.

After moving to Brazil from Italy in 1946, Lina Bo Bardi questioned rationalism and became interested in modern Brazilian architecture and organic architecture. However, her encounter with avant-garde theater and popular art in Salvador, led her to reevaluate the essence of rationalism: humanism and life-based simplicity. She demonstrated the value of rationalism with her masterpiece São Paulo Museum of Art, 1968, which was conceived with a drastically simple spatial organization and raw, rustic materials, as a new synthesis of her thoughts and experiences, including her interest in rural architecture in her early career in Italy.

This paper investigates how Frank Lloyd Wright was evaluated in the shelter magazine The House Beautiful. Previous studies have posited that the magazine had a consistent value and confused Wright’s ideas with those of editors and social reformers. However, Wright himself was not involved in the editorial process, and the magazine’s editorial policies changed according to the opinions of readers and contributors. This study focuses on changes in assessments of houses designed by Wright. Thus, this study describes the struggle over policies regarding housing issues among architects, editors, social reformers, and readers.

This paper aims to clarify the trajectory of the exploration of folk objects by the 20th century French architect and decorator Charlotte Perriand, and to identify the evolution of the subject found in her work. In Perriand’s case, from the 1930s to the 1960s, she studied farmhouses in the West and in Japan to study the scales and gestures of human space. What Perriand found there was not something universal, but rather the very possibility of a variety of gestures. In particular, her theme of mountain dwellings was a representative of this research.

It is undeniable that the Stonborough Villa was completed with the involvement of the philosopher Ludwig Wittgenstein. However, the architectural contribution of Paul Engelmann, who was commissioned by Margaret Stonborough to design the villa, should not be overlooked. Generally, his are only described as resembling a Loosian design because Adolf Loos was his mentor.

In this paper, Engelmann’s 79 sketches will be analyzed in order to examine the logic and floor plan transformations found in the earliest designs of the Stonborough Villa. These sketches allow us to understand the boundaries and inherent logic that Wittgenstein and Engelmann applied, thereby revealing more precisely the architectural features that Engelmann conceptualized.

Taking Suzhou villages in China as cases, this study focuses on the utilization of traditional dwellings in historical villages. In response to the impacts that utilization may cause on heritage conservation, an evaluation approach based on heritage value is proposed. Through theoretical studies using literature and field survey, it identifies four evaluation dimensions – historic, artistic, cultural, and social value – and proposes three criteria for each dimension. Then, the priority of the criteria and the application of the approach are discussed. This study hopes to provide a reference for decision-making and post-evaluation of relevant utilizations, promoting effective heritage conservation.
