This study evaluated home improvements with a focus on reducing the burden of caregiving for elderly caregivers, using a web-based survey of caregivers over 65 years old.

Home improvements were evaluated according to seven questions including caregiver’s physical and psychological burden. Percentage and mean comparisons of the obtained data revealed that home improvements aimed at facilitating the care receivers’ walking and reducing the caregivers’ burden were effective for the caregivers.

Furthermore, it was found that the involvement of care managers and multiple medical workers in the improvements affected the reduction of the caregiver’s burden.

This paper focuses on Korean villa gardens, examining the spaces and sceneries created by the integration of indoor and outdoor areas of the buildings.

Analyses were conducted on the relationship between psychological evaluation and spatial composition of these spaces, where the following results were obtained: Villa gardens strongly reflect [Architecture] and [Nature], while the impression of [Artificial] elements is weak. Psychological evaluations indicate characteristics such as <Richness of greenery>, <Natural environment>, and <Open>. These are closely related to either, a concentrated range or a mediumrange distribution of [Nature].

Efficient boarding of passenger aircraft is crucial for on-time departures. Delays often arise when passengers stop to stow baggage or check seat positions, blocking narrow aisles. This study aims to identify and address these delays by simulation model constructed based on observed passenger behaviors from video surveys. We simulate various boarding scenarios, evaluate boarding completion time, and identify boarding methods to optimize the boarding process. Our results suggest an effective method to reduce boarding completion time and improve overall boarding efficiency.

The author relocated to Ofunato City, an area affected by the Great East Japan Earthquake, to conduct fieldwork. This paper examines the environmental transition through a case study of the author’ s experience. The findings reveal that environmental transition unfolds in three stages: first, the author consciously takes on roles that can be fulfilled; second, the author is able to be in the place before these roles are recognized by the community; and third, the awareness of the need to take on roles faded, and the self-perception shifted from being an outsider to someone standing on the boundary of the community.

This study on the awareness and participation of residents in Xuwan Village regarding the issue of vacant houses centers on the impacts of these vacant homes on the sustainable development of the local community and the preservation of traditional buildings. It delves into the current situation of the increasing number of vacant houses in Xuwan Village and their socio-economic and cultural repercussions. Employing a mix of literature reviews, on-site surveys, questionnaires for residents, and in-depth interviews, the research methodically investigates the residents’ awareness, attitudes, and their level of engagement with the vacant house issue.

Through long-term tracking of vacant houses in hilly and mountainous areas, we clarified the existence, actual conditions, and owners’ intentions regarding long-term high-quality vacant houses. In this study, we focused on vacant houses that have maintained good condition for over 10 years despite aging and deterioration, and we identified their trends and characteristics. Additionally, from the results of a questionnaire survey, we found that about 20% of vacant house owners consider their vacant houses to be their “original home” and regard them as very important buildings.

We proposed “Satoya” as an intermediate category between “vacant houses” and “living homes.”

The living environment of technical intern trainees in fishing boats complies with legal standards for four reasons：First, the fisheries industry provides strong protection for technical intern trainees, with supervisory bodies (fisheries cooperatives) and training providers managing the technical internship programs under the guidance of the central fisheries organizations. Second, since remote islands are more community-based, there exists stronger ties between its residents. Third, hierarchical relationships in fishing boats promote adherence to communal living standards. Lastly, there is a high level of legal recognition concerning accommodation for technical intern trainees in fishing boats.

We conducted a series of “Town of Memories Workshops” in areas affected by the tsunami and nuclear accident following the Great East Japan Earthquake, targeting residents and others. The workshops featured diorama models that reconstructed the pre-disaster townscape and were displayed for approximately one week, providing a space for participants to share memories of the area before the disaster. The workshops were well-received, with many participants in their 40s and older sharing stories about the region’s charms before the disaster. However, challenges include that the workshops may not always lead to successful outcomes, and some participants experienced emotional strain.

This research aimed to compare the effect on the ease of crossing a station of the Continuous Railway Grade Separation Project and the Transportation Nodal Project by three modes of transport: car, foot, and bicycle. The comparison was made using GIS with detour rates. The result showed the range of effects of the Continuous Railway Grade Separation Project on cars is limited while on walking and bicycling they are significant. The stations where both the projects were implemented are difficult to reconcile cars and the others. In above-ground stations, the installation of underground passageways is effective.

Recently, many provincial cities in Japan have experienced a decline in downtown area. However, considering that they have diverse functions, advanced infrastructure, and efficient social capital investments, it is necessary to maintain and revitalize them. This study analyzed the relationship between daytime population concentration and characteristics of facilities and locations in downtown areas. The results showed that while there were some differences in the characteristics of urban areas affected by weekdays and holidays, the most influential indicator was commonly peripheral population density, and the effects of the concentration of facilities and the floor space of shopping centers were also confirmed.

This study examines characteristics and differences of residential life in Mayuan, Kunming, using questionnaires and interviews with aborigines, residential-only tenants, and residential-business tenants, focusing on micro-scale patterns and group disparities.

Findings show that aborigines prefer long-term, multi-generational living in low-rise buildings of northern area, while middle-aged residential-business tenants cluster in the southeast area. Both groups value residential comfort, with northern residents reporting lower levels of satisfaction. Conversely, younger residential-only populations in new area prioritize economic factors, short-term living and spatial flexibility. These results highlight the importance of adaptive planning to address diverse needs, foster integration, and alleviate dissatisfaction of residents.

The effects of street space development in commercial spaces were analyzed from the following three aspects.

1. The causal relationship regarding the impact of street space development on land prices was examined using DAG.

2. I conducted a propensity score matching analysis to quantitatively analyze the effect of street space development on land prices. The effect of the development is immediate, with an initial effect of about 20%.

3. I analyzed the time series variation of the effects of street space development and found that the effects are maintained over the long term.

This study investigated the current situation regarding securing housing for patients with environmental hypersensitivity. As a result of a questionnaire survey of patients with environmental hypersensitivity, it was found that even after a long time since the onset of the disease, many patients could not secure adequate housing. As a solution, it was confirmed that there is a possibility of establishing a supply and demand for housing that considers indoor air quality. Improving the methods of mitigating the influences from the surrounding environment and providing information to patients could increase the provision of housing to patients.

The purpose of this study is to clarify distribution price and ownership cost of incentives for the market distribution of vacant detached houses in rural areas. As a result of conducting a questionnaire survey in Hokkaido, we estimated functions that can predict with high accuracy the distribution price and the ownership cost of vacant detached houses from the fix asset taxes to achieve the target market distribution rate. It is possible to estimate economic incentives and disincentives for the market distribution by comparing the market price or tax burden of the houses with the estimation result of this function.

Continuous and Repetitive Work Method in high-rise building construction is essential for the stable employment of workers and the enforcement of learning effectiveness. The scheduling for this method, however, is very difficult to achieve an adequate work process for low-rise building construction which has not enough repetitive works. The author expanded the conventional method, and proposed a new approach for the scheduling using mathematical optimization, then applied the method in low-rise building construction.

‘Tengu-Hozo’ is a construction technique that involves joining vertical members using a tenon. This technique was widely used in Japan from the Kamakura period through the Middle Ages in general, and declined in the early modern period. Although it is considered to be an application of the structure of penetrating ties, there are examples of its widespread use in floor, shaft and shed framing. In floor framing in particular, its role in reinforcing the footing of the pillars by extending the ends and one end of the horizontal structural members of a building is particularly prominent.

・This was realized through negotiations by the mayor of Isohama.

・The designer of the Seizoden could not be determined, but the exhibition hall was designed by Taketomi Eiichi.

・The design was based on Western historicism, which contrasts with Oarai Isosaki Shrine.

・The decoration was simplified, showing characteristics of historicism from the early Showa. Like Seizoden Hall, the Exhibition

hall retains elements that express symbolism.

The National Memorial Ceremony for the War Dead is now customarily held annually at the Nippon Budokan. In this paper (Part 2), the venue plannings from the 1950s to mid-1960s are analyzed the following changes are identified: (1) basic composition of the venue planning and its diversity, (2) changes in ceremonial platform, (3) introduction of Gozasho, seats for the emperor and empress. Based on this, it is pointed out that the absence of permanent monuments and the disconnection with the surrounding urban space were the characteristics of the ceremonial space of the emperor facing the war dead in post-war Japan.

This paper explores the Indian-style Taihoku Higashi Honganji completed in 1936 during the Japanese occupation of Taiwan. Through articles found in the Ōtani-ha journal Hikari, it reviews the construction process, and identifies the role of Takechi Yukifumi as the director architect assigned by Matsui Construction. The study also situates the Taipei one within the context of Tsukiji Hongwanji designed by Ito Chūta. The author critically examines the name of the style designated in the Taiwan Architecture Journal, suggesting it stems from a misreading of Tsukiji Hongwanji, which reflects the ambiguity surrounding architectural styles of the time.
