The objective in this paper is to investigate effects of policy signals by central bank, monetary policy committee, and government, respectively, on financial variables in Korea. It is found that policy signals by government officials have relatively stronger effects on variabilities of financial variables than those by central banker. Also, it is shown that monetary policy signals by central banker or government officials may be focused on business cycle rather than inflation although the only objective of monetary policy in Korea is to stabilize inflation. Moreover, monetary policy committee frequently follows policy recommendation suggested by government officials. Thus, it is necessary to consider the change of the current Korean monetary policy framework(inflation targeting system).

The objective in this paper is to investigate Issues of long-run neutrality and long-run superneutrality for Korea using Fisher and Seater (1993) model and to analyze effectiveness of money as an information variable under the Korean monetary policy framework. It is found that money is long-run neutral and that the long-run superneutrality of the narrowly defined money can not be rejected. However, broader-based measures of the money stock such as M3 are not long-run superneutral. This finding suggests that money is long-run neutral within the Fisher and Seater (1993) framework. Also, the introduction of dummy variables to capture recent extraperiod, the Korean financial crisis, does not change the findings. Thus, since the money stocks have proportional relationships to both price and nominal output from the long-run viewpoint, long-run effectiveness of monetary index, which a role as policy index recently weakened, has been remained.

This paper compares the performance of banks with and without effective government control in appointment of chief operating officers in Korea using panel data. A privatization program succeeded in spreading ownership of banks widely among the public. Government retention of an ownership stake in an institution meant de facto control by government, decision-making subject to political objectives, and more severe problems of political loan. A model is presented in which political loans are a constraint on banks subject to strong government influence. It is found that banks strongly influenced by government experienced disproportionately bad loan performance and were inefficient compared to privately controlled banks m terms of levels of employment, total costs, and profits.

토압의 변동에 관한 연구

In the development of engineering designs, decisions are required irrespective of the state of completeness and quality of information, and are formulated under conditions of uncertainty. Furthermore, under conditions of uncertainty the design invokes risks. Thus, in the design of the structures, the currently used deterministic design method does not provide a realistic assessment of the actual safety or the reliability of the structures. It is desirable that decisions required in The process of the design invariably must be made based on the reliability analysis. Properties of soil material are subject to more uncertainty than those of other structural material. In the field of soil mechanics and foundation engineering, it needed to develop reliability-based design methods. In order to simplify the reliability analysis or the reliability-based design process of the structures associated with the active earth pressure, it is necessary to find the variation and the distribution type of the active earth pressure calculated from the basic properties of soils. Monte Carlo simulation is performed to obtain the relationship between the variation of the active earth pressure for cohessionless soils calculated by using Rankine formula and the basic soil properties and the distribution type of the earth pressure. A series of regression equations obtained by utilizing the multi-linear regression analysis is suggested in this paper and the sensitivity of the basic soil properties to the variation of The earth pressure is investigated. The type of distribution of the active earth pressure was found to be the beta distribution in most cases or to be very similar to the beta distribution, if the basic soil variables are normally distributed. 모든 설계는 정보가 불완전하고 또 불확실성 하에서 이루어지고 있어 재난을 초래할 수도 있다. 구조물 설계시에도 현행 결정론적인 설계방법은 구조물의 안전정도나 신뢰도를 나타내지 못하고 있다. 설계시 모든 사항들은 신뢰도 해석에 근거해 결정하는 것이 바람직하다. 토질에 있어서는 다른 구조재의 성질보다 불확실성이 더 크기 때문에 더 큰 문제를 내포하고 있어 신뢰도 해석에 의거한 설계방법의 연구가 절실한 형편이다. 주동토압에 관계되는 구조물의 신뢰도 해석이나 설계의 과정을 단순화할 수 있도록 확률변수의 수를 줄여 토질의 기본정수로부터 계산되는 토압을 하나의 확률변수로 간주하고 토압의 변동계수 및 분포형태를 구할 필요가 있다. 모의실험을 사용하여 사질토의 Rankine 주동토압들을 계산, 통계처리하고 중선형회귀법을 통해 기본 토질정수와 토압의 변동계수의 관계를 구할 수 있는 회귀식들을 제시하였고 각 기본 토질정수들이 토압의 변동계수에 미치는 영향을 분석하였으며 Pearson system을 이용하여 토압의 분포를 분석한 결과, 기본 토질정수들이 정규분포일 때 토압은 베타분포로 간주해도 무난할 것으로 나타났다.

地下埋設 管渠에 作用하는 荷重의 變動에 關한 硏究

In the structural design of pipelines, the currently used methods do not provide a realistic assessment of either the actual safety of pipelines of the reliability of pipe response under a assumed service loading. This may be largely attributable to the inadequate determination of design factors that currently enter into calculations are in reality associated with some uncertainty. In order to study and suggest the design method for underground pipelines based on the reliability analysis several design parameters should be handled, and the design method may be very complicated and unconvenient to use. Among the design parameters, the loads acting on the pipeline due to the backfill are usually being calculated by using the Maston's formula which also contains several design factors. Therefore, it is considered to be reasonable that the loads on the pipeline are taken to be one random variable to simplify the design procedure. The parameters related to the backfill load are considered to be random variables, and random numbers of the parameters are generated. The backfill loads are calculated by using the generated random numbers. The results are analyzed by the multiple linear regression technique, and regression equations, by which coefficients of variation of the backfill loads can be calculated from the design parameters related to the backfill loads and their coefficients of variation, are proposed and the type of the distribution for the calculated backfill loads is investigated.

確率論에 依據한 地下埋說 剛性管渠의 構造設計 方法에 關한 硏究

Until recently the current design procedure for underground rigid pipelines has been dominated by deterministic thinking, characterised in design calculations by comparing the minimum supporting strength of the pipeline with the maximum applied load on the pipeline. This procedure does not provide for a realistic assessment of either the actual safety of structures or the reliability of the pipe response. In this study, probabilitic theory was employed to relate the safety implications of the current design method to the past experience and a reliability-based design method is proposed. A computer program was made, based on the level Ⅱ method of reliability analysis and a series of computations was conducted. From these results, a series of graphs was prepared, showing the relationships between the probability of failure and total applied load on the pipeline, the global factor of safety or the partial tactor o| safety. By the use of these curves, for the given total load, probability of failure and coefficients of variation of materials, the pipe strength and the bedding factor, the appropriate foundation type and bedding factors can be found.

In the design of pipelines, the currently used methods do not provide for a realistic assessment of either the actual safety of a structure or the reliability of the pipe response under an assumed service loading. This may be largely attributable to the inadequate definition of the supporting strength of a pipeline and to a lack of knowledge of the exact nature of the the loading on the system. In this study, probability theory was employed as a comparative tool relating the safety implications of the current design method to past experience. In order to calibrate the current design method with the limit state design procedure, the probabilities of failure and partial safety factors for design parameters were computed by using computer, in accordance with the Level Ⅱ method of reliability theory. The computed results showed that the design results based on the current proceduresfor the pipeline design have a probability of failure of about 2.5%, according to the limit state principles and when tighter supervision is exerted reliability of the pipelines can be increased greatly without changes in safety factors ; reliability of 99.95% can be achieved by reducing the coefficient of variation of 10% in the bedding factor.
