A model for predicting room fire in fully developed stage is developed for the purpose of estimating the heat release due to the combustion of the excess fuels involved in the external flames ejecting from the windows of fire rooms. In this model, the burning rate is predicted as a function of the predicted heat transfer to the fuels. The model does not need to introduce adjusting factors, such as the "complete combustion rate (=0.6)" by Kawagoe et al., to get reasonably good prediction of room fire temperature. The predictions of the temperatures and the burning rates are compared with the results of preceding experiments to demonstrate fair agreement.

The purpose of this study is to evaluate quantitatively the effect of a passage width on choice of egress route at a T-junction. Two experiments were carried out to clarify the behavior of egress under forrowing two conditions. (i) Showing subjects VTR images of T-junction under the limited information of egress route, (ii) Using the simulator system driven by the subjects themselves under the condition that subjects can search for information of egress route freely. From results of the experiment, following two points became clear. (1) Almost 70%〜90% of the evacuees can be led to safety egress without emergency guide lights or emergency guidance, when the relative ratio of the width of the right passage at a T-junction to that of the left one is approximately 1.7〜2.5. (2) There is no difference in choice ratio of a wide passage, in case that relative ratio of the width at a T-junction is over 2.5.

In this paper, we examined the effectiveness of carrying out sound field evaluations by conducting articulation tests using a tri-syllable sound source with the rate of speech varied between four patterns based on the results of envelope analysis of conversational speech and evaluating the results comprehensively for the purpose of evaluating speech transmission properties in room sound fields. We carried out the measurement of ″ease of hearing″on a psychological scale and tri-syllable articulation tests with varied speech rates in various room sound fields with differing echo-diagram response properties and specifically studied the effects of reflected sound on hearing, while conducting comparative examinations of correspondence to test results on a psychological scale. As a result, we found that there was a favorable correspondence between tri-syllable articulation evaluation with varied speech rates and the″ease of hearing″as well as wide range of application to various room sound fields. We, furthermore, considered criteria for the evaluation of tri-syllable articulation tests with varied speech rates from the standpoint of assuring intelligibility from the correspondence of word intelligibility.

For the control of structure-borne sound, the evaluation of the propagation properties of the vibration in buildings is very important. In this paper, a method for the calculating the complex amplitude of vibration acceleration in three-dimensional framed structures is described. It deals with quasi-longtunaidal waves and bending waves. Wave transmission theory and the Lagrange's equation are used to formulate motional equations and energy equivalence equations for an element. A simulation and a model test were performed, the analyses and the measurements corresponded satisfactorily.

The brightness of a room interior can be roughly determined from its luminance. However, the luminance of a room interior is not even, but rather is an amalgam of high-luminance areas and low-luminance areas. In this research we intended to determine the effect of luminance distribution on brightness. First, we conducted a experiment to estimate the brightness of stimuli that are of the different luminance distribution. Next, a experiment that examined the relationship between the characteristics of luminance variations and brightness in interior environment was conducted. As a result, the brightness in a room interior depended not just on luminance of visual field but also on the distribution of field luminance, and that although luminance distribution that originates in the varying reflectance of walls and floors does not affect brightness to a great extent, the luminance distribution resulting from non-uniform lighting caused an interior to seem darker.

This paper presents some Monte Carlo simulations for the calculation of illuminance of interiors including the component caused by reflected light. The authors at first argue about what the necessary and sufficient condition is with regard to Monte Carlo simulations for the calculation. In this paper, the condition has been translated into a different expression so that it may be conveniently applied to the simulations for reflected luminous flux from surfaces of interiors. After showing the condition, the authors give some newly-devised simulations togetter with a conventional one, discuss their validity, and compare advantages and disadvantages among them.

This paper describes a newly developed evaporative-cooling wall constructed of water-permeable bricks containing thin-rectangular ventilation channels that allow flow-through air passage. Perforated bricks were experimentally manufactured after investigating brick materials and baking conditions in terms of water permeability and absorption. The cooling effect of a water-saturated brick was measured and expressed as the ratio to the difference between upwind wet and dry-bulb temperature. In addition, we built a mock-up wall which could be filled with water by incorporating a feed device. The wall was found to stay uniformly moist with an adequate water supply, and cooling efficiency was sufficient during the summer of Tokyo.

This paper intends to clarify the evolution of wooden framing systems in Westernstyle schools during the Meiji and Taisho periods. At the beginning of Meiji, framing was irregular as some columns were placed based on window position as well as the traditional module. In the middle of Meiji, two framing systems co-existed : one based on window arrangement and the other based on the traditional module. From late Meiji, the width of windows was neither determined by the frame arrangement nor the traditional module. This transformation reveals the process of standardization within wooden-frame schools in terms of columns and windows arrangement.

This paper analyzes how the shopping behavior of consumers influences upon retail facility location within the context of multi-purpose shopping. We make a model of optimal frequencies of single- and multi-purpose trips and derive the degree of multi-purpose shopping from it. It is shown that consumers' spatial behavior is a function of their locations relative to retail facilities. This analysis is then utilized as an input to the profit-maximizing equation of retailers. The model is illustrated through the use of numerical analysis.

The results of research are as follows ; the former sector had belonged to the civil engineering section and needed a long term to establish architectural organization, and the latter sector had an early chance of independence, because of supervising the building law. As two sectors were independent each other, the staff exchange between two sectors had not existed. The actual number of staff on both sectors had differed from the number which were regulated by the local authority law.

(1) As for the vertical proportion, the Academy admitted, besides vitruvius' method of dividing the total height of the capital into three parts (that is, abacus, echinus, and necking) of the equal height, the proportion with a abacus that is taller than the other parts. (2) As far as the moulding under the echinus is concerned, the Academy admitted first the annulets, and then the astragal that is a commun feature of the Doric capitals used in the Parisian churches of the 17th and 18th centuries. (3) As for the projection of the capital from the surface of the columnar shaft, the Academy criticised Vitruvius' small one, and admitted the wider ones. The final capital represented by Tannvot's design is in a sens an amalgam of these complicated arguments on the three aspects.

The late 1910's is the period when J. J. P. Oud came to be widely known as a modern architect by contributing essays and projects to the periodical De Stijl. One of his contributions, published in 1917, was titled as "Het monumentale stadsbeeld." The present paper is an attempt to investigate the 'monumentale', an essential concept to understand what Oud was preoccupied with and how he viewed architecture itself, at that time. Careful study of his praises and criticisms towards Berlage and Amsterdam School clarifies the fact that he interpreted this concept in terms of the antithesis between the individual and the universal.
