We discuss the problems in the reconstruction process of housing area, heavily damaged by the Hanshin-Awaji earthquake. We choose Sumiyoshi-area and analyze the transfigurations of this area before and after the earthquake through periodical field work survey and existing sources. Before the quake there exist problems as follows ; the mixture of detached houses and large RC condominiums and small timber apartment houses, the existence of some highly dense blocks with very narrow paths inside, many small lots and lots without appropriate accesses. Two years after the earthquake, October 1996, the reconstruction process of this area is revealing the hidden problems before the earthquake.

Sitting behavior is changed diversely depending on the setting of bench even if its feature is almost same with others. We observed people with paying attention to sitting behavior each five-minutes interval in the morning (10-11 am), in the afternoon (1-2 pm), and in the evening (4-5 pm) on a weekday and a holiday. We analyzed the relation of sitting direction and behavior. The results of this observation are as follows: 1) The characteristics of sitting behavior have diversities with the user attributes (age-group, gender), term, and physical features. 2) People can utilize the space diversely according to the physical situation (park entrance, plaza). 3) In the case of the benches setting on between the pond and the sidewalk, the sitting directions effect an alternation of the place mood.

Stochastic properties of broadband strong motions are investigated using the fractal source model. The model is described by the limited dynamic data reflecting uncertainty and heterogeneity on the fault plane. The soil ground model for source-site path is presented by the theoretical Green's function of the multi-layered half space. The simultaneous simulation test has been tried for the recorded ground motions at some sites in the 1994 Northridge earthquake and the 2000 Western Tottori prefecture earthquake. The average spectra and the duration time of the synthetics correspond well with those of the observed within 20 kilometers from the fault region.

The purpose of this study is to understand the role of rehearsal rooms and stages in creation of a stage drama. For this study, we investigated the entire creation of the play, from the first rehearsal to the public performance. In fact, the actors and staff spent most of their time in the rehearsal room until the play was completed. Therefore, the rehearsal room has to be the same size as the stage and backstage areas to provide the same width and height, as well as all essential facilities. Furthermore, it is also important to plan the rehearsal room comfortable, because sometimes actors and staff may use it to take breaks.

The dining kitchen is the housing style after World War II. The dining kitchen has spread to Japan based on "55-4N-2DK" of Japan Housing Corporation. It turned out that "55-4N-2DK" was the same as civil servant apartment "RC52 type". The root was "Wohn Kuche","Wohn Kuche" was researched in Europe after World War I. I defined this process, "Process of Wohn Kuche". In the background where the dining kitchen was born, there was a theme of housework reduction of the housewife. There were five stages in the forming process of dining kitchen. I defined, "Theory proposal period", "Model proposal period", "Experimental period", "Development period", and "Established period".

In making proposals for PFI project, we can see remarkable conduct as a specialist. Such conduct is quite different from the other design-communication, especially in housing environment design. And it is characteristic in their situated actions as "being the member." Ethno-design-method is inevitably working in such situated process practically. This paper aims to describe the ethno-design-methods which are found in their decision-making for programming, planning and designing facilities by participatory action research and analysis of conversations between members. Making proposals for PFI project develops through the collaborative practice by trial and error. The ethno-design-methods as collaborative practice were found as comprising (a) making agreeable responses to confirm explanation and intention, (b) interrupting except the end of utterance and (c) suggesting ideas or questions euphemistically.

By introduction of concept-Autopoiesis, I am trying to make better relationships between Architectural Design and planning theory. According to N. Ruhmann, human and human-society are classified 3 autopoietic systems,namely Body-system,Mind-system and Society-system. This 3 systems corresponds to Architecture consisting of 5 parts,(1) Architecture as efficiency,(2) Architecture as functional-space,(3) Architecture as feeling-space (4) Architecture as information,(5) Architecture as system's structure. These 5 parts have the effectiveness for Architectural valuation.

In order to clarify the prediction accuracy of Boussinesq approximation, natural convection in a enclosure with heated and cooled vertical walls is analyzed by CFD technique based on Boussinesq approximation and low Mach number approximation. In the case of ΔT=300℃, the difference of the velocity profile between Boussinesq approximation and low Mach number approximation is great, and about 20% of the maximum velocity in the perpendicular direction. The cause which produces such a difference is mainly due to fact that the density of air in the continuity equation is constant in Boussinesq approximation.

The occurrence of earthquake ground motions exceeding the assumed design level may lead to plasticization of the superstructure of seismically isolated buildings. It is known that the plasticization of the superstructure is accompanied by a rapid development of deformation (quasi-brittle). In this paper, the relationship between the Ds value and the ductility factor is determined using incremental dynamic analysis, and the nature of quasi-brittle is quantified by formulating this relationship. Furthermore, seismic safety evaluation method for the limit state of seismic isolation layer and superstructure in seismically isolated buildings is proposed using this relationship.

This study aims to develop a theoretical foundation for considering architecture as knowledge commons. The findings of commons research were applied by setting research questions on 1) how architecture can be considered as knowledge commons and 2) what kind of architecture can be defined as knowledge commons. The achievement of this study is to present an analytical framework called the AKC (Architecture Knowledge Commons) framework, which is an application of the IAD framework, the core methodology of commons research, to architecture, and to identify the theoretical conditions for considering architecture as knowledge commons.

This study aims to estimate the man-hour rate of construction management that can be performed in off-site. In Japan, shortages labor due to a decrease in the working-age population is becoming obvious, so improvement of productivity is pointed out as an issue in the construction industry. Construction management activities are becoming more efficient, but it has remained in the incremental improvement in many cases and not yet to achieve a radical review, called BPR (Business Process Re-engineering). There is the idea called shared services that is one idea of the BPR. Shared services are the internal service provider that to perform the specific operational tasks such as an accounting operations and human resource management. By applying shared services, it is possible to perform activities intensively and efficiently in specific department that is being performed in separate departments.  Most of the construction management activities are characterized that being performed by each site. For this reason, drastic improvement of activities can be achieved by introducing shared services concept. Thus, this study estimated the man-hour rate that can be performed in off-site. In this study, we utilize the activity data that is revealed by the process chart method, which is one of the methods of Industrial Engineering. The data includes the name of 436 activities and the man-hour rate. Though it is not in a statistically significant because of the data from a single site, the data is valuable that records the activities that is performed from before construction to after completion.  There are various factors of constrains in off-site management. In this study, it was classified into physical constraints and operational characteristics of activities. Classification of physical constraints were determined by whether the activity contains a task that must be performed in the field or not. And classification of constraints by possibility of standardization were classified activities into highly specialized, specialized, and non-specialized. The activities except for the “highly specialized”, can be standardized.  The result of the classification based on the two constraints, it was found that 216 activities (man-hour rate:28.4%) can be performed in off-site. Because of the man-hour rate accounts for a large proportion, it has been suggested that introducing shared services can contribute to improve the productivity in the construction management activities.

In recent years, there is concern about the occurrence of extreme ground motions that greatly exceed the amplitude levels and durations expected in conventional design level. Therefore, seismically isolated buildings are required to secure the seismic isolation performance for small earthquakes and to suppress the excessive displacement of the seismic isolation layer for extreme ground motions. As one of the effective means to meet the above requirements, in addition to an electromagnetic switching semi-active seismic isolation system, a cheaper and more reliable passive damper is being developed. Meanwhile, the authors have proposed a dead zone mechanism that is an accessory device connected to the existing oil damper. When the relative displacement of seismic isolation layer is smaller than the set amplitude (medium and small earthquakes level), the dead zone mechanism only slides and no damping force is generated in the oil damper, and when the amplitude is larger than the set amplitude (extreme ground motions), this mechanism generates damping force and suppresses excessive displacement. Furthermore, one of the features of this mechanism is that it has a mechanism that automatically returns the rod to the original position after the earthquake. In this paper, we analyze the seismic response of seismically isolated buildings using the dead zone mechanism to understand the response characteristics.  1) When the publicly announced wave and pulse ground motions are used as input earthquakes, an oil damper with a dead zone mechanism is used in the seismic isolation building to ensure seismic isolation performance for small and medium earthquakes, while suppressing excessive displacement of the seismic isolation layer for extreme ground motions. It was confirmed that the desires effect of doing was obtained. In this analysis case, the most effective performance was shown when the dead zone width was set to 15cm. 2) When the long period ground motions is used as the input ground motions, the acceleration response of the GAP model is larger than that of the OD model, but the acceleration is small at about 100~200cm/s2, which is considered to be within the allowable range for seismic isolation. 3) It was confirmed that the automatic return spring in the dead zone mechanism automatically returns the rod in the mechanism to the neutral position at the end of the earthquake. Therefore, by automatically returning the dead zone mechanism to the automatic return spring in the dead zone mechanism, it is possible to maintain the structural performance assumed at the time of design even when multiple earthquakes occur in a short period of time. 4) In all earthquakes, when the seismic isolation layer displacement reaches the dead zone width, the absolute acceleration increase in the lower layer. The cause is considered to be a reaction force due to the elements of the dead zone mechanism contacting each other. The 1/3 octave band analysis was applied to the time history waveform of the absolute response acceleration above the seismic isolation layer of each model. It was confirmed that the value was sufficiently smaller than the judgment value of the rank with the lowest anxiety level, compared with the evaluation curve in the anxiety level evaluation by Takahashi et al. Therefore, it was confirmed that the increase in acceleration response when the elements in the dead zone mechanism were in contact had little effect on the habitability.

Experiments and questionnaires were conducted at an elementary school to determine the effect of environment monitoring system on ventilation behavior. The LED lamp display according to the carbon dioxide concentration served as a criterion for decision-making on ventilation behavior, and the percentage of carbon dioxide concentrations exceeding the standard (1,000 ppm) decreased for many classrooms. Alternatively, in some classrooms, excessive ventilation was fixed, and the thermal environment was also improved. Moreover, the children’s involvement in opening windows for ventilation increased.

Aiming to understand distribution of exposed value throughout Japan in the 21st century, this study quantitatively analyzed risks of earthquake, flood, and sea-level rise using 500m mesh with population, asset, and geospatial information. The following presents the results.1. 25.5% of the residential area, 50.9% of the population, and 36.9% of the assets are in the areas with altitude of less than 25m.2. Population and assets are more concentrated in areas at high risk of sea-level rise than in areas at high risk of earthquakes and flooding.3. Places with higher disaster risk have lower rates of population decline.

The Shikoku pilgrimage route consists of 88 official temples and numerous other sacred sites located around the island of Shikoku. There are some accommodation options for the pilgrims. However, there are only a few choices for low cost accommodation. Zenkonyado is an accommodation where the local residents or homeowners welcome Shikoku pilgrims to stay overnight for free or at a low cost. This is based on Shikoku Pilgrimage culture called Osettai.  The aim of this paper is to clarify: 1) The characteristics and problems of the housing spatial layout and management of the Zenkonyado; 2) The needs and the challenges of the pilgrims; and 3) The future direction of the Zenkonyado.  Methodologies used are: 1) Interview with the owners of the Zenkonyado; 2) Measurement of the space and the equipment; and 3) Survey questionnaire for the pilgrims.  The study found that for Zenkonyado: 1) Converting unoccupied houses is effective as it allows full use and utilization of unused rooms and facilities; 2) Socio-cultural exchange was made easier and more convenient for pilgrims and Zenkonyado managers to take part in; 3) Safety and privacy of the managers and the pilgrims are ensured; and 4) A number of aging managers and the changing manners of pilgrims, who stay in Zenkonyado, are some of the issues that could possibly make continued operation of the accommodation difficult.

In this paper, we examine the residential area of Oji Paper Co. Ltd. Tomakomai factory. The residential area had located around the factory. Officers area located near the main office, and the welfare buildings had a high amenity for officers. Worker's area located around officers. Officers area didn't expand but got number of residence increased. Almost all the houses made from wood, and served out by the company until WWII. The structure of the houses changed into concrete blocks or RC. after the war. Many welfare buildings were there in this company town, buildings for officers, like club-house, were built led to workers before 1933. After that, the welfare buildings were served for all employees without difference of class after 1933.
