  • 사장교와 같이 바닥판 지간이 장지간이면서, 중량 절감 효과가 크게 나타나는 교량 형식에 경제적으로 적용할 수 있는 FRP-콘크리트 합성 바닥판을 개발하고, 이의 정적 성능을 실험을 통하여 확인하였다.

  • Muscle specific tyrosine kinase (MuSK) myasthenia gravis (MG) is a rare subtype of MG, which is immunologically distinct and differential therapeutic response. Though MG is often associated with other autoimmune disorders or malignancy, concurrence of other disease and MuSK MG has been infrequently reported. We present a patient of MuSK MG associated with multicentric Castelman disease.

  • We consider the empirical Bayes confidence intervals that attain a specified level of EB coverage for the scale parameter in the Burr distribution under type II censoring data. Also, we compare the coverage probabilities and the expected confidence interval lengths for these confidence intervals through simulation study.

  • Bridge deck is the element presenting the largest damage potentiality among the major bridge structural members. In the previous study, a new-type of FRP-concrete composite bridge deck system was proposed and its static performance was experimentally verified, This study aim at investigation of fatigue behavior such as failure mechanism through rolling fatigue test.

  • We consider the estimation of parameter in the exponential model in the case that the number of replacements of failed items is limited. And the desirable number of replacements to give the similar effect as unlimited case in terms of the mean square errors is proposed.
