The Bayes premium or the net premium in the credibility theory does not reflect the underlying tail risk. In this study we examine how the tail risk measures can be utilized in determining the risk premium. First, we show that the risk measures can not only provide the proper risk loading, but also allow the insurer to avoid the wrong decision made with the Bayesian premium alone. Second, it is illustrated that the rank of the tail thickness among different conditional loss distributions does not preserve for the corresponding predictive distributions, even if they share the identical prior variable. The implication of this result is that the risk loading for a contract should be based on the risk measure of the predictive loss distribution not the conditional one.

빗물을 노상 침투시키는 투수성포장은 물순환 보전과 차량 주행 안전성 확보와 같은 효과를 기대할 수 있다. 지금까지 보도나 주차장 같이 비교적 교통조건이 열악하지 않은 구간에 적용되고 있지만 우수 침투로 인해 노상이 연약화 될 것을 우려하여 현재까지 차도에 적용하지 못하고 있으며 설계 방법 또한 정립되어 있지 못한 실정이다. 본 연구에서는 투수성포장의 포장단면을 설계하기 위한 방안으로 단지내 포장을 투수성포장으로 설계할 경 물의 침투로 인해 노상의 지지력이 약화 된다고 가정하고 노상 지지력의 약화에 따른 포장층의 역학적 거동 특성을 유한요소 해석을 통하여 분석하여 구조적 안정성을 확보할 수 있는 포장두께를 분석하였다. 또한 설계 개념에서 노상의 지지력 저하에 따른 포장두께의 할증방안과 할증두께를 분석하였다.

In order to identify positive or negative effect of seawall on wind turbine, a wind tunnel experiment has been conducted with a 1/100 scaled-down model of Goonsan wind farm which is located in West coast along seawall. Wind speedup due to the slope of seawall contributed to about 3% increment of area-averaged wind speed on rotor-plane of a wind turbine which is anticipated to augment wind power generation. From the turbulence measurement and flow visualization, it was confirmed that there would be no negative effect due to flow separation because its influence is confined below wind turbine blades' sweeping height.

In order to calculate construction costs properly, it is necessary to add the weight that reflects different worksite conditions. The implementation of the weight, however, is difficult because it is impossible to determine whether wight should be added in basic work or whether weight values are overlapped. Special worksite conditions further complicate the matter. Furthermore, overlapping implementation of weight values result in overestimation of construction costs. The current study clearly analyzed the weight value items in the current construction cost calculation standards, and analyzed the weight value items included under the basic productivity category to propose an improvement of weight standards. Basically, the estimating standards provide 140 weight value items, with different levels of weight given to each item. Among 1,333 items in the estimating standards, 140 include weight values. Some items have two types of weight values.
