This study investigated the behavior of sediment bars in a compound channel with a drop structure. Flow was separated into side banks by alternate bars, and flow was concentrated into the downstream of bar fronts. The bed downstream of a drop structure degradated due to the concentrated flow from it. Bar shapes were kept by the influence of their shapes upstream. Alternate bars, central bars, and multiple bars were developed as the width to depth ratio increased, and the number of bars increased. The bar in the downstream of a drop structure decreased in length due to the concentration of flow and its disturbance.

We setup a continuous measurement system for electrical conductivity of fluid in a model borehole and verified the basic environments in electrical conductivity measurement for estimating hydraulic constants. The experiment was made by monitoring the conductivity change within the hole using NaCI solution of different salinities and incoming formation fluid using distilled water. The experiment was made under the state of constant flow rate by maintaining balance between inflow and outflow. Conductivity variation features were observed by controlling salinity contrasts and temperature differences between fluid within the hole and incoming formation fluid. flow rate and the location of inlet and outlet. The results of the experiment show well the role of each affecting factor on the conductivity distribution. and suggest appropriate environments for conductivity measurements. It is considered that the basis of the conductivity measurement for henceforward laboratory model and/or in-situ borehole experiment has been prepared.

The purpose of this thesis is to study concept of "the Publicity" in ancient classics in Asia. I refered to Book of Odes( 詩經), Analects(論語), Mencius(孟子), Collections of Chu Xi( 晦華集), Ri zhi lu( 日知錄). This thesis is to classify and reinterpret the concept of "the Publicity". The major types of it are as follows : first, "the Publicity" as the ascendancy of the king in Book of Odes. second, "the Publicity" as hereditary order in Analects, third, "the Publicity" as authority of the king in Mencius, fourth, "the Publicity" as political ascendancy in Collections of Chu Xi, fifth, "the Publicity" as public and private uniformity in Ri zhi lu.
