The purpose of this study is to make it possible to predict the behavior, particularly the deformations, of steel frames subjected to lateral forces. The authors have previously proposed the extended slope-deflection method for elasto plastic frame systems in consideration of shear deformation of joint panels. In this paper, the assumptions of this method are discussed and the upper and lower bounds for the initial stiffness of steel frames in the elastic range are explained by using the energy method. The approximate expression for the stiffness of transversely loaded steel frames in the range of strain-hardening is made. Next, a series of tests of transversely loaded steel frames were carried out in order to examine the propriety of these methods. The specimens used in these experiments were constructed of rolled H-section members (JIS SS 41) : one group consists of four kinds of one story one bay portal frames and the other of two kinds of two story one bay frames. Comparing the test results with numerical calculation from the proposal theory, the following conclusions were obtained. 1) The initial stiffness of the test frames was between the upper and lower bounds calculated by the energy method. 2) The stiffness of the test frames in the strain-hardening stage were approximately satisfied with the following expression 1/(3n-2)・K_i, where, K_i : initial stiffness of a steel frame subjected to a lateral force, n : ratio of the strain at the initiation of strain of strain-hardening to the yield strain in a stress-strain curve. 3) According to the strength of the joint panels, the behavior of steel frames subjected to lateral forces only is varied.

This report shows one of the experimental results as for elastoplastic behavior of I-section beams with high-tensile-bolted joints under repeated pure bending. Some of the results of the study are as follows : 1) The rigity of high-teusile-bolt-jointed beams is very high as compared with rivet-jointed beams and is almost the same as a jointless beam. 2) The load at the first major slip of high-tensile-bolt-jointed beams is higher than the computed value. 3) The load-deflection curves of high-tensile-bolt-jointed beams show a peculiar saw-tooth form after the initial slip. 4) The load at first major slip tends to decrease with repetition of loading. 5) The clamping force in the bolts tends to decrease with increasing load, the amount of reduction being most pronounced at the flanges in tension.

The sound insulating mechanisms of sandwich panels which consists of two surface sheets with another layer inserted bed between them, are classified into three groups by the acoustical properties of the inserted material, as follows 1 Rigid Type, 2 Elastic Type, 3 Resitivity Type. These three mechanisms are simulated by electrical curcuits and then theoretically their brequency characteristics of sound transmission loss are obtained. Also the sound transmission loss of 12 kinds of practical sandwich panel has been measured at our laboratory using international method recommended by I.S.O. The theoretical and experimental results are corefully compared in order to obtain a practical method of designing sandwich panel which hrs desired frequency characteristic of T.L.

Number of beds in hospital used to be considered as a principal index on the calculation for the scale of Paramedical facilitis. But actual number of in-patients and out-patients have influence on the utilization frequency of paramedical facilities. In this paper I made an analisis on the correlation between these factors, and tried to set a principal index for calculating the scale of Param-edical facilities. Main materials for the study are The Annual Report of National Hospitals, (1960〜1964), (By National Hospital Section, Medical Affairs Bureau, Welfare Ministry.) Firstly, Yearly change of utilization frequency and Utilization rate of Para-medical facilities per patient was analized, and correlation between three factors : number of paramedicale facilities utilization per day (z), number of new-in-patients per day (x) and number of new-out-patients per day (y) was analized, and then formula of Regression Plane was set up through the correlation between these three factors. As the result, the fallowings were confirmed; (1) (x) and (y) are in propotional relation, and (x) and (z) are in propotional relation, and (y) and (z) are in protional relation. (Fig. 1〜6) (2) On the calculation for the (z), (y) is not so much important factor as (x) (3) Adaptability between calculated value and measured value was analized on each (z). The result was as follows, i) (z) indicated high approximation in surgical operation and direct xray examination. ii) (z) indicated low approximation in radiological therapy and physiological examination. iii) (z) indicated no approximation in test in the clinical laboratory. (4) Required number of operating tables or radiographic units could be calculated through diniding the calculated value by the handling capacity per operating table or radiographic unit per day.

The report (IV) continues the report (III) in which problems is treated "by prefectures". In this place economic index, it is thought of expressing regional levels of constructive activity, index number of population and other indexes are compared with constructive activity. In consequence it was cleared that economic index was concerned in determining levels of constructive activity. But the concernment is not conclusive. It was known that the scale of constructive activity was determined in very complex mechanism.

The building of the Sale and Reception Room of the KAITAKUSHI (completed in 1881) was built of bricks of the KAITAKUSHI-controlled Moheji Rengaseki Seizojo. This manufactory was founded in 1872 (Meiji 5) and was locked out in 1881 (Meiji 14). In the latter half of the years the exclusive object of the operation was to furnish materials of the work of the Sale and Reception Room. This paper deals with the productive situation of the said manufactory from 1878 (Meiji 11) to 1881 (Meiji 14).
