In this study, we focused on environmental factors to analyze the suicide problem. A questionnaire survey was conducted targeting people aged 60 and over living in Akita Prefecture. Respondents with a loneliness score of 44 points or higher and a depression score of 10 points or higher were defined as potential suicidal ideation groups and analyzed. From the results of the logistic regression analysis, it became clear that the awareness of the living environment is an effective factor for those who are likely to have suicidal ideation.

In this study, field and questionnaire surveys were conducted in a support facility for persons with disabilities who are aging and severely disabled. The main results are as follows:

1) The residents were categorized into 3 groups. There were differences in the trend of spaces to stay among the groups.

2) Spatial composition in the new facility improved the quality of the life support for day-shift staff.

3) The placement of the medical room next to the staff room changed the life support provided by the nurses.

4) Utilization of ICT equipment had positive effects on night-shift staff.

For obtaining fundamental knowledge about Terminal-care of village, I selected targets of the survey by analyzing demographic change past 20 years and conducted questionnaire survey to government officer and residents. The results of this study are summarized as follows.

1. 82.4% of municipalities had marginal villages.

2. The answerers of residents were classified by 4-type of geological locations and 5-types of formation backgrounds

3. In remaining life of village, 34.2% of the residents answered upper 60 years, but 64.3% of the government officers answered 20~40 years.

4. In the necessity of Terminal-care, the residents had stronger awareness than government officers.

The aim of this study is to make clear the spatial composition and formative process of reclaimed villages by a case study on Kojo Shinden. The reclamation work of Kojo Shinden was performed in the end of early-modern times whereby, large-scale latticed arable land was developed. After that, the characteristic arable land units were distributed by unique process. In this paper, we attempt to clarify the relation between arable land unit and space component which is a waterway, a path and residence on Kojo Shinden. As a result, we revealed the correspondence of the antecedent conditions to the space component.

Redevelopment projects are being carried out to improve disaster prevention performance in some densely build-up areas. However, since these may cause loss of unique residential environments, it is needed to clarify land use level appropriate to each local characteristics for redesign. As the first step, this study estimated land price functions and conducted cost-benefit analysis of created three land use models using these functions to clarify appropriate land use level from economic perspective for three case study areas. The results showed that appropriate land use level differs depending on local characteristics, especially whether it is in metropolitan or provincial area.

Sequence of traditional buildings from boat were analyzed and concluded on following aspects for landscape modifications.

1. Transition of unity evaluation when view from boat were analyzed and it was found that untraditional structure, obstruction of vision and continuous interruption decrease unity.

2. Relations between landscape features and psychological evaluation were analyzed and it was obtained that switching of landscape decrease unity and some mixing untraditional buildings or minor differences of traditional buildings are unrelated.

3. Relations between psychological evaluation and transition of unity evaluation were analyzed and it was obtained that smaller fluctuation of unity make better landscape experience.

Effects on impression by water surface reflection were verified by experiments with participants. As results, light color was more preferred than daylight color. Calmness increased when the luminance value was lower than about 8000 cd/m². The higher the luminance value, the higher the evaluation of sharpness and glitter. When the water surface had small and medium waves, the evaluation value of calmness, glitter and beauty was higher than when there was no wave. Calmness and beauty were rated higher for small waves than for medium waves. Based on the above findings, lighting schemes with water reflections should be implemented.

The 3411 ordinance, a development permit system, has been introduced in many municipalities. However, the increase in development has led to sprawl, and some municipalities have decided to repeal the ordinance. in Kurashiki City, which decided to repeal the 3411 ordinance, we surveyed the current status of development, the living environment of 3411 housing, and residents’ awareness of the ordinance. As a result, we were able to confirm from residents' trends and evaluation of the living environment that the ordinance was repealed because housing development spread over a wide area as a result of not designating land for development permission.

This study focuses on Machi-Libraries, where local residents bring books and build bookshelves for common use, and aims to find out the characteristics of the location tendency in four prefectures. The results show that, while Machi-Libraries in Tokyo and Kanagawa tend to be located close to train stations, some in Osaka and Hyogo are far from stations. This might be related to differences in urban structure, population density and the location of the facility to which they are attached. The results also suggest that the proximity of the Machi-Libraries to others is one of the location factors in Hyogo.

We proposed new indexes (section arrival rate and comprehensive arrival rate) to evaluate the traffic functions of specific emergency transportation roads and developed a simulation system to extract reachable road sections by describing the spatial movement of emergency vehicles. Furthermore, we developed application software that enables us to easily evaluate the impact of seismic retrofitting of specific roadside buildings on traffic functions in order to support the planning process by municipality officials. By analyzing the execution log of the application usage by the officials, we discussed their strategies for promoting the seismic retrofitting of specific roadside buildings.

The discussions of the design of reinforced concrete buildings reached a peak in the mid-1910s, mainly featured with the conceptions of new structural forms like as a single entity and rigid frame together with various manners of architectural treatment, but rapidly declined with no consensus reached. Structural form and architectural treatment were still two coexisting realms, between which the momentum of detachment loomed in the new structural forms of RC. However, the detachment and the new conceptions were limited by the scarcity of actual instances, stereotypes of Japan and the US, and certain conventional values.

Seitogakusha, located on Miyake Island, is an architecture constructed of 5,000 railway sleepers built in 1980 by a group with no architectural background. It awarded the Architectural Institute of Japan Award in 1981. This research attempts to grasp Seitogakusha's design drawings and the design approach given by Architect Takasuga Susumu via gathering and analyzing existing architectural drawings (1976). The following points were revealed. (1) The shape of buttress (Hikaekabe) is related to the wall amount calculation. (2) The size of sleepers derives the architecture module and is delicately linked to the construction method.

Keiichi Morita visited the South Seas—former German then Japanese colonies—in summer 1938 to investigate Indigenous architecture. The newly found sources, however, indicate his interest lay rather in the footsteps of his predecessors, German expedition members. He then recalls these years as ‘a blank period’ later, silencing his South Seas related activities and regarding the ‘primitive architecture’ as belonging to an incomprehensible architectural state of ‘transcendency’. This research elucidates these peculiar behaviours through the lens of Morita’s characteristic attitudes towards his lifelong academic research into classical architectural theories; his belief in the significance of reading the original sources.

In this paper, The row house type buildings under Fireproof Building Promotion Law and Disaster Prevention Building Blocks Construction Act in Japan are typologically analyzed in façade design.

Firstly, the façade design of the row house style buildings is analyzed from combinations of façade elements and composition of those, and classified into several types.

Secondly, each type’s trend in construction age is analyzed.

This research helps to clarify the characteristics of the row house type buildings as one of the urban buildings that formed many shopping districts in the post-war period of Japan.

By focusing on the discussions, remaining in Fonds Jean Drapeau, on the development of the Montreal metro route, this paper shows 3 things.

1. The metro was not initially included in the urban renewal vision of Jean Drapeau, mayor of Montreal.

2. The metro was recognized as an important role not only on linking and developing suburbs as an “miniature metropolis” and but also expanding the downtown area.

3. The metro project promotes to encourage speculation in urban renewal and to modernize the city and establish it as a world city.
