Because cross-section of Prestressed Concrete Box Girder Bridge is usually a closed section, its transverse, longitudinal flexural rigidity and elastic stability are very high. Hence, the bridge is very safe and stable during construction and use, and frequently used in these days. It can be applied with advantages to 60=70m span and curved bridges that have a lot of torsional moments. The Box Girder Bridge transmits the upper weight to a pier and abutment through diaphragm built inside the box girder, and prevents the section deformation by increasing the cross-section stiffness. But, the diaphragm, which includes geometric and static discontinuity, causes a lot of problems to be accurately analyzed and reasonably designed only with Korean Design Codes. When a prestressed force ia applied directly to a diaphragm, a large tension force is built up opposite side and lower part of anchorage zone, which causes bursting stress. Cracks around the anchorage zone are found because of bursting stress. The bursting stress and the tension around the diaphragm are not considered in the Korean Design Code. Hence, the prestress transferring mechanism, the analysis of End Strut and the stability of Lower Corner, are needed to study. Analysis using Strut-and-Tie Model has been performed to transverse analysis of diaphragm. An accurate structural analysis about the anchorage zone has been performed by a jStrut-and-Tie Model based on Area-AASHTO and CEB-FIP code, and their results has been compared with those of the Korean Design Code. It has been found that the Korean Design Code underestimates the shear strength of concrete.

The economic situation in Korea is characterized by high inflation and low saving ratio. By the way, the study of the savings remains in the fundamental level. So, the purpose of this thesis is to provide the better explanatory power relative to the existing studies by means of presenting the effect of inflation on the savings in the theoretical and empirical aspects. The main results derived from the study could be summarized as follows: First, Deaton's model - a model that includes inflation (as well as other factors) directly - has a better explanatory power than the traditional model - a saving function which only has income and interest rate as explantory variables. Second, when the inflation is divided into anticipated and unanticipated inflation, anticipated inflation causes dissaving and unanticipated inflation, involuntary saving. This resultes are caused by the disequilibrium model which is based on the search theory. According to the search theory, consumers encountering an increased price for a certain good may postpone the purchases until a serach of the market confirms that its price relative to all other relevant goods has not changed encough to affect his decision. Since search takes time, consumption expenditures fall, transaction blances accumulate, and the personal saving rate increases. Third, inflation has an effect on the personal or household saving but has no effect on the domestic saving. This result is derived from the variety of the determinants of the savings, and from the uncertainty created by the inflation. Fourth, the variety of the expectation mechanisms does not affect the above results. This is, though inflation has any expection mechanism among static, extrapolative, adaptive, rational expectation the effect of inflation on the savings does not change, but the size of the effect is different. Also, the size of the effect is different according to the time span of the consumer's expectation. That is because inflation expectation in the short run is not complete relative to that in the long run. However, the effect itself is not affected by the time span of the consumer's expectation.

It is difficult to calculate the flexural rigidity of reinforced concrete slender columns under sustained load that will reasonably approximate the variations in stiffness due to creep of the concrete stress-strain curve. In this study, the initial and creep strain were calculated by use of Age-adjusted effective modulus method. Then, the column stiffness was estimated by moment-curvature relationships. This paper is presented a statistical evaluation of the stiffness parameters for use in the design of reinforced concrete slender columns subjected to sustained loads. It is recommended that the creep factor β_d used in current moment magnifier method should be concerned with the parameters affecting creep.

The procedure is computed by a set of points for a constant ratio of bending moments on the three dimensional failure surface and plots the resulting interaction diagram by using computer program「Column」. In this study, the computer program 「Column」 is developed for the nonlinear analysis of arbitrary reinforced concrete sections subjected to axial force and biaxial bending moments. A numerical procedure is performed by an exact analysis based on Davister Method for reinforced concrete columns subjected simultaneously to a combination of axial force and biaxial bending moments. The interaction curve is obtained for the various types (rectangular shape, L-shape and T-shape) of reinforced concrete columns in this study.

The objective of this study is to investigate the behavior of reinforced concrete cobels. In ACI building code, shear-friction analogy has been suggested for span-to-depth ratio less than 1.0, regardless of the failure mechanism of cobels. However, based on our analysis results, it is resonable to apply the shear-friction analogy for a/d ≤ 0.5 and strut-and-tie method for 0.5 < a/d ≤ 1.

It was in 1942 and 1946 that the writer put out two works, Han-Kuk Ko-Ka Yoˇn-Ku 韓國古歌硏究, A Study of Old Korean Songs, and Yoˇ-Yo Choˇn-Chu 麗謠箋注, The Annotating Study of Songs in the Ko-Ryoˇ Era respectively. The former study explains how to interpret and read Hyang-Ka 鄕歌, common name for the songs of the Silla period and the oldest of songs existing in Korea today but being recorded in I-Tu 吏讀 script, and gives a considerably thorough annotation. The latter followed about the same manner as the former, differing only in the material with which it dealt those of the Ko-Ryo˘ era. For more than a decade since these publications, very few criticisms appeared. However, the writer has continued to go through the books several times linguistically, historically, and investigatively. Here in this paper he presents, from this continued study and for the better revision of his books, some point and issues which must be considered in the field. Some of the strong points and difficulties encountered during the course of pursuing his interpretation and study are also added. But particular attention is given to the views and theories linguistically different from the writer such as: 1. Taking consideration of the fact that the Chinese characters ending with Korean "ㄹ" or "l" sound-Ip-So￣ng 入聲, recorded in the Ke-Rim Yu-Sa 계림類事, have two sounds because the original sound is "ㄷ" or "t" whereas the colloquial is "ㄹ" or "l" sound, the characters should be read both ways, according to the Korean words they represent: ex., 漢捺(天), Hanal ; 骨(花), Kot. Nevertheless, there is an erroneous attempt to read them all alike in one way only, the final "ㄹ" sound. 2. I-Tu 吏讀 script "矣" is read ㄷㆎ "Tai", because it is the abbreviation of "冬矣", (which, by the Pan-cho￣l 反切 rule, reads ㄷㆎ Tai). However, there is a vain effort to relate this script to a genetive auxiliarv word (or suffix) "ㅇㆎ Ai" and the nominative case from "ㄷㆎ Tai" of space noun ㄷㆍ "Ta" or its Altaic equivalent. 3. Regardless of the evidence that the sounds "△"(Z or ?) and "ㅸ" "V" were used in the period of the Silla dynasty and in which period they were already vulgarized on the other hand as "mute" and "W", there is a wrong opinion that the two sounds did not exist in the days of Silla and Ko-Ryo˘ dynasties, but appeared in the early days of Cho-So˘n era, and that they disappeared in the middle of the same dynasty. 4. In spite of the writer's discovery of ㅅㆍ "sa" as an incomplete noun for "matter", there has been a misuse of "씨 ssi" as the general term for "partof speech". 5.Against the writer's view that from ancient time the nominat tive auxiliary word (or suffix) "가 ka" has been used in the colloquial as "이 i" in the written language, there is an opinion that "ka 가" did not exist in the old days but that it came out all at once in the seventeenth century, the Cho-So˘n era. But he belives this to be a mistake caused by the inability to discriminate the materials of the written languge and that of the colloquial.
