A questionnaire survey on the definition of homeless people that central governments of OECD countries regularly rely on as well as framework to monitor the scale of homeless problems has been conducted. Results of the survey shows that central governments in several OCED countries do not have their definition of homeless people, and that there is a great disparity in the definitions. In addition, it was found that few countries have established a framework to regularly monitor the number of homeless people. The result indicates that Japan is the countries that has the narrowest definition of homeless people, and one of few countries that have already established the monitoring framework.

A new approach integration heuristics and nonlinear programming is proposed for topology optimization of discrete structures under stress and local buckling constraints. In the approach, the optimal ground structures are searched by heuristics, and topology optimization is performed for each ground structure based on nonlinear programming. Two heuristics are applied; namely, tabu search, and a new heuristic method called topology mining, which is based on the apriori algorithm. Three numerical examples are solved to demonstrate the effectiveness of the proposed approach. Moreover, the efficiency in view of computational cost of the two heuristics is discussed by comparing the optimization results.

Recently, a number of designers have focused on free-form surface shell to realize a free architectural form that is different from the analytical curved surface such as cylindrical or spherical surfaces. However, in order to create rational architectural forms, constructability and cost are also essential factors to be considered. Developable surface is a special form of ruled surface generated by continuous movement of the straight line. It can be obtained by adding the condition that the normal vector of the surface does not change along the generating line (generatrix). Because the generatrix is a straight line without torsion, the formwork of continuum shell is easily created. Since the twisting process is not required, it has a high workability characteristics. In this study, several developable surfaces are combined to form a curved roof structure. The (n,1) Bézier surface is used for modeling the surface. Optimization problem is formulated for minimizing the maximum principal stress under several static loading conditions including vertical and horizontal loads. The coordinates of control points of the Bézier surface are chosen as design variables. The developability condition is numerically assigned so that the tangent vectors at the same parameter value of the two Bézier curves along the boundary exist in the same plane as the directing line. The G0 and G1 continuity conditions are assigned for connecting the Bézier surfaces. Optimal solutions are found using nonlinear programming approach, where the sensitivity coefficients are computed by the finite difference approximation. As the result of optimization, a variety of developable surfaces are obtained by connecting Bézier surfaces. Since the control points of the curves are chosen as design variables, the calculation efficiency is high. The stress distribution also greatly improved by using the maximum stress as the objective function.

In this study, we focus attention on odor of at the time of adult diaper exchange that was the factor to raise odor level in the patient room. An object of this study is to clarify main odor components and odor emission rate from excrement. In addition, we showed clearly the diffusion of the odors at the time of adult diaper exchange with the odor sensor installed in the patient room. The findings obtained are summarized as follows.(1) Odor concentration of excrement changed with the amount of excrement, the treatment contents of the medication, the intake method of the meal and the kinds of the meal, etc. The highest odor concentration was 23000.(2) The highest odor emission rate of at the adult diaper exchange was 460m3/min, and ventilation requirement was 57.5m3/min.(3) We clarified the main components of excrement were “hydrogen sulfide”, “methyl mercaptan”, “isovaleric acid”, “n-valeric acid”, “butyric acid” and “aldehydes”.(4) The odor generated at the time of adult diaper exchange diffused from the odor emission source, and the air current to occur by the work of the nurse influenced the diffusion of odor.

Acacia, False Aacacia and Platanus Acerifolia were three main kinds of street trees planted in Qingdao before the WWII. All of these three kinds of trees were imported to Qingdao from Germany by the German governors since 1898. By doing this, the street landscape in Berlin was reproduced in its colony Qingdao. It turned out that rather than planting trees of their own countries, Acacia, False Aacacia and Platanus Acerifolia were continuously planted in the new areas of Qingdao by Japan and the Republic of China government later. The reason why the continuity of street landscape was well kept is probably because that the street trees were considered as quite important links between the new and old town. However, due to the political reasons, there were no street trees planted in the area where Chinese lived. This problem had not been solved until Qingdao was recovered by the Republic of China government. Nowadays, Cedar is increasingly planted in Qingdao's street and a new feature of street landscape is being created in the city.

Steps are common features in our day-to-day living and working environment. Unfortunately, the occurrence of accidents on or around steps is thus inevitable. A failed visibility to see or recognize a step remains the most common attribute in these accidents. Surprisingly, appropriate methods for examining and quantifying step visibility have yet to be established. In this research, sensory scales of step visibility were created in order to examine the effects of two factors on step visibility in sensory testing methods; observation distance from step and observation action while viewing a step from the descending direction. Results of sensory and statistical tests revealed that step visibility tends to decline as observation distance increases, and the quality and tendency of step visibility in different observation conditions varies based on the unique and individual visual characteristics of each step.

In this research, the outdoor thermal environment around residential buildings with and without greens were measured in winter and summer, and the following results were obtained. 1) In summer and winter, outdoor air temperature is 1.5K lower in the green space than in the no green space. 2) In summer, ground surface temperature is 8.3K lower in the green space than in the no green space. 3) In summer, moisture ratio is 1.1g/kg' lower in the green space than in the no green space. The results show that greens are effective to moderate air temperature, ground surface temperature and humidity. Heat mitigation effect of trees extends to out of tree shade. According to this measurement, the optimal green plantation is about 4.5m in height and 4m away from the building.

About 60,000 fires occur per year in Japan. Of them, over 30,000 cases were building fires. And burnout floor area is about 1,500,000 m2 per year. It is preferable to decrease the number and scale of fires. The purpose of this study is to analyze the behavior of fire and its spread. To analyze them, we used fire statistics which is available to the public. At the beginning, the object region was the whole of Japan. The second object is Government-decreed cities and Tokyo's 23 wards. We analyzed the rate which is the fire spread and non-fire spread. Next there search was the correlation between the burnout floor area of the fire origin building and the burnout floor area of buildings damaged by fire spread. The result shows that the Fire spreading is not a special thing as the side of the month. The burnout floor area increases as the number of burnt buildings increases. It is different from each region that the calculation guidelines about burnout floor area. There is poor correlation between the burnout floor area of the origin building and the burnout.

In our resent paper, we explained the planning method of the column interval dimensions of Horyuji Kondo (the main hall of Horyuji temple) by adopting the mediaeval period's 'shiwari-sei' as a clue. However, what seems to be lacking is the consideration to the Pagoda in Asuka period. This thesis deals with the method for designing the standard unit of the column interval of Horyuji Gojyu-no-tou (Pagoda of Horyuji temple) and Hokkiji Pagoda. These Pagodas have the same measure and the method founded on the primitive 'shiwari-sei' as that of Horyuji Kondo and Chumon.

In the case that citizens participate in making plans of their own towns, there are two possibilities. One is participation in town planning conference and work shops which are prepared by local government, and the other is petition to local assembly. Especially song of city, citizen charter and city declaration are the important variation of citizen participation on the latter case. The purpose of this paper is to point out the importance of Wago, the words which have their origins in the ancient Japanese, as a premise of citizen participation about the case of citizen charters of Tokyo.

Since the law of city planning was revised in 1992, citizen participation in town planning has become active all over Japan. However citizen charter, which ought to be called the constitution of town planning, has never been studied enough in spite of including much possibility about the style of participation. The purpose of this study is to clarify the present condition of citizen charters in Japan and to consider its meaning in town planning through the view point of citizen participation.

Community action groups are expected as new groups to support the life of the community instead of territorial groups. In recent years, “Community design” that the expert support to forming community action groups to solve regional problems is getting a lot of attention. In our preceding paper, we classified members in community action groups into 3 types of participation motivation: “type of using spare time”, “type of desire for recognition from others” and “type of self-actualization needs”. The aim of this study is to clarify the relationship between the roles of members and the motivations to participate community action groups. First, We prepared 12-items of roles of members in community action groups(Table2). We performed the questionnaire survey by the mutual vote method by using the 12-items targeting 106 members in 8 groups. By factor analysis using answers to the questionnaire, it was clarified that the construction of roles of members in community action groups was composed of 3 factors: “Diplomatic and intellectual role” factor, “Leadership role” factor and “Behind the scenes role” factor. (Table4) Second, The role types of members in 8 groups were classified by cluster analysis as follows: “type of all-around leader”, “type of supporter” and “type of follower”(Fig. 5). The members of “type of all-around leader” showed strong leadership and play a lot of roles in the groups, especially to provide and gather the information, to bring their cooperators and to consider about their activities. The members of “type of supporter” were situation to support and always cooperative with activities of groups. The members of “type of follower” played the leading role in comparison to the other types. Third, we investigated the relationship between the roles of members and the motivations to participate community action groups. The result was that there were tendencies to be a lot of members of “type of desire for recognition from others” and a few members of “type of using spare time” in members of “type of all-around leader”, and a lot of members of “type of self-actualization needs” and a few members of “type of desire for recognition from others” in members of “type of supporter”. On the other hand, there were tendencies to be a few members of “type of self-actualization needs”. (Table6) Finally, we investigated how did the action type of groups have an effect on the roles of members. The result was that there were tendencies to be a lot of members of “type of supporter” and a few members of “type of follower” in “action type of player”. On the other hand, there were tendencies to be a lot of members of “type of follower” and a few members of “type of supporter” in “action type of area manager” (Table7). And the participation motivation of members had an effect on both of the action type of groups and the roles of members, in other words, the action type of groups made complex the relationship between the roles of members and the motivations to participate community action groups (Fig9, 10, 11).
