방제비용 선지급제도는 재난적인 해양오염사고, 국제기금 또는 추가기금협약의 적용을 받는 해양오염사고 등 방제책임기관이 선지급의 필요성이 있다고 판단하는 사고에 대하여 방제책임기관이 방제업체 등을 방제조치를 취했을 때 주민생계보전 및 영세업체 경영난 해소를 위해 자체사정을 거쳐 P&I Club이나 국제기금이 사정하기 전에 방제비용을 우선 지급하는 제도이다.

When monitoring an instrumental process, one often collects a host of data such as characteristic signals sent by a sensor in short time intervals. Characteristic data of short time intervals tend to be autocorrelated. In the instrumental processes often the practice of adjusting the setting value simply based on the previous one, so-called ‘adjacent point operation’, becomes more critical, since in the short run the deviations are harder to detect and in the long run they have amplified consequences. Stochastic modelling using ARIMA or AR models are not readily usable here. Due to the difficulty of dealing with autocorrelated data conventional practice is resorting to choosing the time interval where autocorrelation is weak enough then to using I-MR control chart to judge the process stability. In the autocorrelated instrumental processes it appears that using the Shewhart chart and the time interval data where autocorrelation is relatively not existent turns out to be a rather convenient and very useful practice to determine the process stability. However in the autocorrelated instrumental processes we intend to show that one would presumably do better using the EWMA control chart rather than just using the Shewhart chart along with some arbitrarily intervalled data, since the former is more sensitive to shifts given appropriate weights.

Engineering valuation is a specialized discipline requiring expert knowledge and judgment, which scientifically estimates the economic value of industrial properties. By industrial properties, we mean engineering structures such as mines, factories, build

시계열데이터는 ARMA 분석에 적합지 않은 요소를 내재하고 있는 경우가 있다. 특히 선형성과 주기성을 가진 요소가 확률적인 분포와 자주 혼재 되어 있다. 이 논문에서는 이런 선형적 주기적 요소를 찾아내고 분석하는 방법을 제시한다. 특히 주기적 요소는 여러 주기가 층층이 겹쳐져서 나타난다， 주기 간에 는 서로 일정 정수비율을 유지하며 ， 한 주기 안에 다른 주기가 내 포되어 있는 경우(nested periods)가 많다. 시간규모(time-scale) 개

There are several techniques to build the lumped-mass stick model, which are tributary-area based conventional model, frequency adaptive model, and advanced model combining the conventional and frequency adaptive models. The present study is to compare the seismic response accuracy of the models including FE model. The target structure is a nuclear containment structure and 45 earthquake ground motions are considered for the seismic analysis. The results show that the advanced lumped-mass model provides similar and more consistent responses to the FE model, compared to other models.

An advanced lumped-mass stick (LMS) model introduced in this paper is to overcome the disadvantages of the conventional lumped mass stick model, such as frequency error and low accuracy of dynamic responses. In order to show the performance of the advanced lumped-mass stick model, the experimental test using shaking table is conducted, considering a scaled four-story frame structure. The material of the frame model is stainless and the total mass of the model is about 39kg. The displacement and acceleration responses resulted from the advanced LMS model are compared with those of experimental results, including the response results of the conventional LMS model of the frame model.
