This paper deals with the propriety of the shear test data with stirrup reported in ACI and ASCE structural journal and the shear resistance characteristics affected by compressive strength of concrere($f_{ck}$), shear span-to-depth ratio (a/d), tensile reinforcement ratio($\rho$), and shear reinforcement ratio($rho_{v}$). The analysis was accomplished by the 242 shear test data. The test data include the flexural failure data around 40$\%$.

In this paper, we develop the reference priors for the scale and shape parameters in the nonregular Pareto distribution. We derive the reference priors as noninformative priors and prove the propriety of joint posterior distribution under the general priors including reference priors in the order of inferential importance. Through the simulation study, we compare the reference priors with respect to coverage probabilities of parameter of interest in a frequentist sense.

In this paper, we develop the reference priors for the common location parameter in two parameter exponential distributions. We derive the reference priors and prove the propriety of joint posterior distribution under the general prior including the reference priors. Through the simulation study, we show that the proposed reference prior matches the target coverage probabilities in a frequentist sense.

In this paper, we develop the reference priors for the common scale parameter in the nonregular Pareto distributions with unequal shape paramters. We derive the reference priors as noninformative prior and prove the propriety of joint posterior distribution under the general prior including the reference priors. Through the simulation study, we show that the proposed reference priors match the target coverage probabilities in a frequentist sense.

A real train load fluctuates along the track because of complicated movements(Bouncing, Rolling, Pitching and Yawing) and rail conditions. This research has for its object in development of a numerical real train load model including fluctuation characteristics of lateral forces. It is based on Klingel movement theory of a wheelset on straight track it presents a propriety of application by comparison between a 3D-Numerical analysis result using this train load model and a measured data. And this paper presents further study subject to improve a method about the train load modeling.

In this paper, an aberration free aspherical lens is designed and machined by new design method and the spherical aberration measuring system is developed. It confirmed the propriety of new design method by measuring optical characteristics of machined lens with the new measuring system. The system could measure a spherical aberration quantitatively by using CCD camera, laser, collimator and so on.

This study is the consideration of related characteristics between infants of the kindergarten and the lower level children of the elementary school. The characteristics of infant's growth show the homogeneous and successive peculiarity in the aspects of physical, intellectual, emotional, language learning and social development and the characteristics of moulding expression show similarity in developmental stage. So, It is proper that the mini-school for the lower level students of kindergarten and elementary school could be built as the branch unit of neighbourhood.

In this paper, we designed a high precision Linear Motor Driver with 120 commutation method. It was composed of three parts which were divided into Power and Inverter Circuit, Analog Circuit with PWM Generation and Fault Protections, and Logic Circuit We selected LC-DSP by MEI for testifying a high accuracy of a designed driver. We proved the propriety as measured the accuracy with each velocity.

Combustion of coke grains in a pellet used to be modeled using the shrinking core model in the previous indurator simulations. This leads to the discussions about its propriety due to the fundamental assumptions of the model inconsistent with the particle characteristics. The current study presents the grain model as an improvemen, and the differently used reaction models are compared. In addition, the simulations assuming changed particle conditions are conducted to display the effects of using the grain model.
