A model for urban evacuation in multiple disasters of earthquake, fire and tsunami was proposed. This model is an extension of existing model only for urban fire in which the effect of wind-blown fire plumes on evacuation behavior is formulated by introducing a potential concept. Evacuation simulation for coastal densely-built urban area was conducted to verify the model's predictive functions through two thousand trials in which multiple disasters following the Nankai Trough Earthquake were assumed.

In order to understand structure of factors in installing smoke alarms in ordinary houses, we constructed a structural equation model by simultaneous analysis of several groups to interpret and give consideration. For the analysis we used existing survey data which was obtained on a previous work by a questionnaire on residents in detached and owned houses in Joso city, Moriya city, Kasumigaura city and Ishioka city, Ibaraki prefecture. Investigating signs and values of the path coefficients, we found that features of the models on each city were mostly similar except for the factors of support measures by the municipal authorities. And, the model showed that "fear image of smoke alarms" had the largest influence upon whether the respondents had installed them or not. The result suggest that measures to sweep residents' negative impressions of smoke alarms are more important to promote installing them than uplifting people's fire risk perception and announcing effectiveness of the equipment.

The purpose of this study is to discuss the validity of junior high school districts as the basis for setting official senior care service areas. The results of a survey of one hundred and seventy-five (175) senior people show that the actual living spheres of elderly people match, on average, two or three elementary school districts and that local organizations take responsibility in these elementary school districts. Therefore, it can be argued that junior high school districts are meaningful as the standard for official care service area settings, because they are group units of a few elementary school districts.

Abstract: The purpose of this paper is to clarify the historical transformation of the urban park in mountain foot areas of Dalian City in China. Dalian is famous sea-side city, having beautiful mountains as a background of city. Therefore, how to preserve the mountain scenery is one of the essential issues of Dalian. We chose Laodong Park as a study site, since it has a long history from the end of the 19^th century. The following three points are clarified. The first is the planning principle of the park differed, based on the political reasons. In Russian era, the park was a buffer zone between Chinese people and European people. In Japanese era, the extensive park plan was implemented, and basically it has been succeeded after the Chinese revolution. Secondly, however, there exist the strong principles related to the geography and landscape. We analyzed three landscape units and these units succeeded more than one hundred years. Thirdly, the various needs to the park have been solved by changing and adding the facilities within the landscape units. We conclude based on the fundamental principles caused from these landscape units, it becomes possible to manage and preserve mountain foot landscapes in Dalian.

There are a lot of unexpected design changes which can occur during a construction project at the request of various participants. Factors such as initial cause, requestor, change content and occurrence timing further complicate matters which can lead to positive or negative effects accordingly. Therefore it is important to understand the character of design changes made during each project by classifying and defining these factors, in order to make adequate decisions to control future design changes. This paper deals with design change from initial request to response, including the decision making process, and is based upon 2 steel fabrication projects. Projects were selected based upon different delivery methods: as design-bid-build (DBB) or design-build (DB), in order to compare the difference of delivery method to design change. Firstly, the project organization and general work process of each project, as well as production design processes, are introduced. Also, detailed information of design change response process is analyzed, focusing on the decision making and response cost of design changes. Finally, the scenario based simulation is performed, in order to clarify the increasing tendency of response cost of design changes on steel fabrication projects.

“Diary of Masakiyo Mishima, Shogun's Vassal” is a fine historical text, wrote by one adopted Samurai, Masakiyo Natsume who was one of the cadences in Natsume Family, inherited Mishima Family even after Mishima Family suffering from lapse of the official heirship, which is called “Matsugo-youshi” in the inheritance process of Samurai class in the Edo Era. The diary covers the years of ending Edo Era up to the beginning of Meiji Era with very detailed descriptions in the form of time-series. Because Mishima Family was classified as one of middle-class clans of Shogun's Vassal, thus had a main manor (Kami-yashiki) as well as a sub manor (Shimo-yashiki), we can follow how he did with the manors stipulated by the conventions of that time on household, family system as well as estate, which were all impacted with the revolutionary changing happened with the collapse of Tokugawa-House (Tokugawa-Bakufu). We abstract several interesting issues from the architectural (or social scientific if we like to say broadly) point of view, and discuss on those.

Giannozzo Manetti (1396-1459) is a famous humanist in an intellectual circle of pope Eugenius IV and Nicholas V. De Secularibus et Pontificalibus Pompis is a detailed description of the consecration of Florence Cathedral in 1436. This text has caught the distinctive features of architectural ekphrases of the fiftteenth century in Italy. I regarded Giannozzo Manetti as an “architect” in the Early Renaissance. Based on my analysis about De Secularibus et Pontificalibus Pompis, it is reasonable to suppose that Giannozzo Manetti is a rival of Alberti in the practice of architecture.

This paper interprets persuasively on side as representational medium in architectural planning of lineamentum in Alberti's architectural theory. We made the interpretation, on the basic nature that our previous paper has clarified of the lineamentum, by analyzing the use of perscriptio among his architectural, picture and sculpture theories. The result is as the following; the side of the lineamentum is, essentially, the representational medium (signum) that represents analogically the geometrical representational medium (perscriptio). It is, so to speak, semi-geometrical figure, more simply, figure. But the figure actualizes with the lineamentum at the two scenes that is meant by limbus.

The aim of this study is to clarify the expression of comparing size of spaces by arrangement of room in contemporary architecture. This expression is made by the conbination of ‘parameter’(showing difference of scale) and ‘constant’(showing identity of scale). At first, we clarify ‘direct comparison’ and ‘indirect comparison’ as two method comparing with the size of several rooms, and draw the heirarchy chart which shows how ‘parameter’, ‘constant’ and these method are combined in every expression. Finally 7 types are defined through the combination of some heirarchy chart in one architecture, and as a result, the form is revealed that the combination of these two method bring the diversity and complexity to the expression of comparing size of spaces by arrangement of room in contemporary architecture.

This study clarifies how a Din-a-ka (a roofed walkway), a remarkable characteristic of historical city landscaping in Taiwan, led to problems of control and correspondence in their administration. A Din-a-ka was formed in 1900 by the “Taiwan Building Regulation”. It was put in place in the scope of the City improvement project that was carried out throughout Taiwan, starting in 1905. A Din-a-ka had two aspects: while being private property, it was also public space. This is because a Din-a-ka was the walk way connecting the private properties along commercial streets. A Din-a-ka would often lose its function as a walkway, due to the fact that the owners of the occupied the space with goods and empty boxes and their children rode their bicycles along it. In 1918, the Street control regulation was promulgated. By giving the police a legal basis for managing a Din-a-ka, the consolidation of a Din-a-ka gradually continued. In the street control regulation, a Din-a-ka was recognized as private property but was officially given the status of a public walk way.On the other hand, the aligned perspective of a Din-a-ka itself was considered to be a form of beauty. According to this view, the urban beauty of Taiwan was an extension of the Japanese urban beauty campaign.
