In this paper, we propose a new morphological analysis method to evaluate architectural space. Specifically, we focus on the inner convex spaces as a partial inner space and enumerate all possible patterns. Since people can recognize each other in a convex space, they share five senses such as seeing each face, talking without being distracted by any obstacles. It means that a convex space is appropriate as one unit in the architectural space. Recently, some real architectural buildings have complicated and amorphous shapes with seamless special connections. In such buildings, the convex space could be a useful tool to comprehend the spatial composition. Therefore, we regard the building as concave polygons and enumerate all possible patterns of maximal inner convex space. The maximal convex spaces are enumerated in the following procedure. First, the possible candidates for the endpoints of the maximal convex spaces are enumerated as much as possible. The candidate points can be obtained by rotating lines around each reentrant angle of the objective concave polygon. Next, by confirming visibility, half-plane, and tangent line conditions, we create an adjacency matrix for candidate points. Finally, based on this adjacency matrix, we enumerate all possible maximal cliques, which correspond the maximal convex spaces for the analysis. Derived inner convex spaces can be applied to various architectural planning issues. For example, we can clarify the characteristics of inner spaces such as area, circularity. These results indicate the diversity of usage in objective architectural space. Furthermore, the distributions of inner spaces correspond to the openness of space. If space is overlapped by various convex space, it is for public usage and vice versa. We also analyze the connectivity of each inner convex space by connecting centroids by a minimum spanning tree (MST) based on the similarity. This structure would be the backbone of architectural space. Since we enumerated all possible patterns of inner spaces, it enables us to find the optimal inner spaces subject to various conditions. The optimal inner space which maximizes area, circularity, and so on, helps to understand the abilities of buildings. We believe that these new analyses expand the potential of quantitative researches for architectural planning. This study can be regarded as a critical extension of Isovist theory which has been used in numerous earlier studies because a scanning vector which constructs the Isovist is a proper subset of some maximal convex spaces. All of the above computational procedure can be completed within a realistic time, and we believe that this study proposes a new possibility of morphological analysis for architectural space. Future prospects include developing methods applicable to more complex buildings, extending the method to three dimensions, and establishing useful search methods.

Ventilation calculation is important for prediction of heating/cooling load and indoor air quality in residential buildings. In past several decades, many simulation programs are developed for building research and design, but they generally need many input data and complicated modeling. A simplified and accurate prediction method is essential for speedy and convenient ventilation calculation during building design and performance evaluation. In this paper, thousands of ventilation cases are calculated by COMIS ventilation simulation program for a single room house. Using simulated results and ventilation theory, a simplified model and chart for ventilation rate is proposed in consideration of building air-tightness, type of ventilation system and climatic condition. By comparison of COMIS program and the simplified method, it can be found that there is a good agreement with relative error of less than 5 %. In addition, this simplified method is used for a study on building air-tightness level of a solar house having a forced supply ventilation system of heated outdoor air by solar collectors.

The overarching objective of this study is to develop the numerical model based on logistic equations that predict fungal proliferation and colony forming by taking into account the influence of moisture, temperature and surface characteristics of building materials for various fungi. Toward this end, this paper provides the results of fundamental experiment which measure the responses of fungal mycelium length and colony size on culture media under various environmental conditions. The characteristic of this experiment is to make the suspension that strictly controls the density of the spores, and to execute both the mycelium growth experiment on glass plate and the colony formation experiment on culture media with the same slurry of fungal spores. We focus on humidity effect on fungal growth and mycelium lengths were directly measured by using the digital image data with the microscope that had been taken a picture every 24 hours. Obvious humidity dependence of fungal growth was confirmed in this experiment. In this research, we propose the fungous growth model based on a logistic expression and reports on the result of doing the fitting of the model coefficient by using the experiment data. The results of fungal growth model by logistic expression were in reasonable agreement with the experimental data.

This study conducted an empirical investigation of life satisfaction of residents living in super high-rise housings. We investigated life satisfaction of residents, and households with small children and elderlies who live on upper floors. Depending on the residential floors, home satisfaction, health status, and stress frequency differ. The degree of life satisfaction of child-rearing households is influenced by "the home satisfaction", "view from home", "health condition" and other factors. Elderly people's life satisfaction is influenced by "the home satisfaction", "view from home", "health condition", "stress frequency", and "the long chat time" has a negative effect.

This study aims to clarify color transition of Kobe's townscape from the middle period of Meiji until now. Painted colors of western historic houses of Kobe have been investigated. On the other hand, a comparative analysis of Kobe and Hakodate's townscape have been conducted to the study. Obvious characteristics throughout the study are summarized as follows: 1) It has been known that Kobe's houses have been characterised by different colors, for example, external walls and windows are painted respectively by off-white, light beige (for walls) and, green and brown (for windows and posts). This study has obtained that different colors were used. Before the 1960s various and dark colors, especially dark green and gray, were popularly used. Since 1980, various influences of sightseeing and designated historic district, have affected changing the color of these houses to off-white color. 2) The changing of townscape color of both Kobe and Hakodate are different. Incase of Kobe, the townscape color did not chang for about sixty years and was stable for a long period, while Hakodate's case has shown different performance, hence their houses have been characterised by changeable color for a short period every twenty or thirty years.

Recently, an increasing number of urban areas have established neighborhood committee organizations. We investigated organizations established in the 1970s and those formed from the 2000s in the Tokyo metropolitan area. Comparisons reveal that their performance and appraisal by local governments differ despite their almost identical organizational structure. If local governments expect them to serve as necessary planning units for urban management, then it is important that they have legal and political stability to local assemblies and community organizations. Local governments should have them participate in policy-making processes to enhance members' motivation. Furthermore, facilitative leadership encouraging social entrepreneurship is necessary to vitalize these committees.

We analyzed the relationship between results data, obtained through a resident satisfaction survey, and population data taken from basic resident registries. The results of this analysis are as follows. There was a strong correlation between resident satisfaction and population change, a weak correlation between Civic Pride and population change. Each of the factors “image”, “friendliness” and “lifestyle convenience”, “Cost of living” was positively correlated with population growth, while the factors “quietness/security” and “nature/sightseeing destination” were negatively correlated. There was a positive correlation between “Pride of city” and population change, a negative correlation between “Network of many acquaintances” and population change.

It is the representative example that the castle walked it with the history of the modern cultural properties protection as a historic spot in the modern times, and it is the example of the park of historic interest in modern times, but there are extremely few places where it may be said that the maintenance was over.This study considered it about the historical park and the change of the use patterns that the change of a preservation and the idea of practical use, the characteristic performed in a castle in the modern times before the full-scale business of "preservation and maintenance about the historic spot" of 1965 enforcing it after the abandoned castle of modern times castle appointed to a history of nation trace.As for the reconstruction maintenance, as for the element of the point such as the building, the space of the circle that used the reconstruction as a garden of the parks moves to the reconstruction of an open space and the building, but suitable correspondence is late by the reason of the use as the park about the tree in the castle. In addition, it is clear to be the obstacle which is covered the scene as the historic spots such as Ishigaki or the building and the tree which became higher, and fail even if it planted a tree by a plan.

Most exterior walls of wooden residential buildings in Japan have a vented air space between the exterior cladding and insulation. This air space is designed to dehumidify exterior walls by discharging humidity to the outside and taking outdoor air into the walls, in order to decrease the risk of condensation on exterior walls in winter. Many studies have been carried out on vented air space, and the most effective thickness for dehumidification has been determined. However, most of these studies have only investigated the performance of vented air spaces under laboratory conditions, and the characteristics of vented air spaces in the field have not been clarified. Our previous study clarified the characteristics of ventilation volume through the vented air space based on field measurements. This study continues that work by reporting on the hygro-thermal characteristics of vented air space. Temperature and humidity were measured in an experimental house built in Iwate prefecture, and the hygro-thermal characteristics of the vented air space were verified. Temperature and humidity in the vented air space were affected by the outdoor temperature and humidity during most periods of time, except when the wall was exposed to solar radiation. Indoor temperature and humidity had less of an effect on the vented air space, because the walls of the experimental house are well insulated and highly moisture proof. The temperature of the vented air space is 20 or 30 degrees higher than the outdoor temperature when exposed to the sun during the day, and the humidity of the vented air space also rises. It is thought that the rise in humidity is due to moisture desorption from the exterior cladding. The vented air space of the east wall that is exposed to the sun in the early morning tends to have high humidity for a short time because moisture desorption from exterior cladding occurs when the temperature of the wall is low. Solar radiation on the wall also produces a temperature difference between the vented air space and the outside that is one of the driving forces of ventilation in the vented air space. So ventilation volume tends to be high when the wall is exposed to the sun, and low at night time. This means that ventilation volume in the vented air space is high during moisture desorption from the exterior wall cladding and low during moisture absorption. As a result, most of the desorbed moisture from the exterior cladding is discharged well by the ventilation, and the absolute humidity in the vented air space is kept lower than that outdoors. Through long-term measurement of the hygro-thermal characteristics of the vented air space, it was shown that absolute humidity of the vented air space is lower on the average than the outdoor air due to daily variation in ventilation volume and moisture absorption by the exterior cladding. A numerical simulation was conducted and the results of the field survey were simulated. The hygro-thermal characteristics of the vented air space, moisture absorption by the exterior cladding and drying of the vented air space over the long term were generally confirmed.

The following information was revealed about the reconstruction of main halls. 1. The main reasons for reconstruction of former main halls were deterioration, natural disasters, upgrading of functions and war. 2. The structure of the main hall was wooden in 80%. The use of non-wooden structures peaked in the sixties, but wooden structures have increased again since the eighties nationwide. 3. Reconstruction of main halls could be categorized into those attributable to deterioration, disaster, upgrading functions and no reconstruction. 4. Passing down over many generations and placing importance on tradition will be a guideline for reconstructing the main hall.

The Float Parade in Gion Festival changed its traditional route in 1956. This paper investigates the reason in relation with the policy of Kyoto municipality at that time. As the result, two facts have become clear: Firstly, the local government had set the Float Parade as a stake for tourism policy, and a greater street was needed for mobilizing the greater number of tourists. Secondly, there was Oike Street expanded just after the WW2, for which the Float Parade was introduced to make that use as "a new main street of Kyoto" as it were it "a new main street of Kyoto" as it were called then. These two political intentions could have been strategically combined to push the dramatic shift in the ritual inherited over generations.

The Ferro-Concrete structure technology was introduced into Japan in 1890s. In this paper, we try to show that a purpose of the spread played an important role for introduction of Ferro-Concrete in Japan. Various calculation formulas and sign of Ferro-Concrete ware introduced into Japan passing many separated ways and coexisted. It is thought that when it establish a law in 1920 and standardized Ferro-Concrete structure technology, economical conditions would be considered for the spread of this technology. However, the policy for the spread was changed by the damage of Kanto Earthquake(1923). And a deformed bar against the policy of the spread was removed at that time. It is thought that the introduction of Ferro-Concrete would be typical example of process to introduce new technology in Japan.

The purpose of this research is to identify the spatiotemporal characteristics of values of living environment, based on the analysis of housing advertisements within the Tokyo metropolitan area from 1980 to 2010. (1)Firstly the values were sampled as 102 groups based on their meanings, and their tendency of increase and decrease was revealed. (2) Secondly the housings were classified into 7 types and their geographical characteristics were identified. (3)And finally the qualitative changes of the values which reflect the transformation of the center of tokyo metropolitan area were revealed, which were represented as “being high-rised” of housings, “being imageable” of the nature, “being security - biased” of safeties, and ”being individual - biased” of families. At the same time in the whole metropolitan area, “being indoor“ of the comfortableness and diversification of families were also identified.

<p> This article considers the reexported / exported countries of iron nails and the reexported / exported iron nails in the prewar period. The following points will be clarified.</p><p> Reexported iron nails could be confirmed continuously from 1883 to 1911, and then intermittently carried out until 1931, mainly in neighboring countries. The amount of reexports is generally 10,000 barrels or less per year, and re-exported products were slightly more expensive than imported products. Iron nails were exported from at least 1921 throughout the prewar period, and from 1932 to 1939, over 100,000 barrels were exported worldwide. </p>
