An algorithm for optimal design of structures with discrete of specified design variables is developed. A computer program is written to test validity and efficy of the algorithm with various example problems of minimum weigh truss design subject to displacement, stress, and design variable constraints. As the results, it is found that the algorithm is highly stable and can be readily applicable to various structural optimization problems with discrete set of specified design variables.

In this study, a computer program is developed for analysis of the preflex composite beams which is able to calculate automatically the bending stresses and deflections for every construction steps in order to examine whether the maximum values are within the allowable ones or not. To verify the accuracy of the proposed computer program, its results are compared with those by the other theoretical studies. Using the proposed computer program. In this study, the various influence of design parameters are studied and their results are analyzed. In this study, the structure used in parametric investigation is preflex composite bridge with the span length of 30 meters, the girder height of 1.2 meters and the girder distance of 2.8 meters. A total number of parameters are nine which is used for the analysis. From the results of parametric investigations considering the construction steps of preflex composite beams, the stresses at lower flange concrete are closed to allowable ones and their influences are very sensitive. To extremize the efficiency of the section design, the safety of lower flange concrete must by guaranteed and the accurate structural analysis must be accompanied.

알쯔하이머는 독일 프랑크푸르트에 있는 정신병원에서 목격되고 병원장 지올리씨가 그에게 그 중추신경계를 검사하도록 위임한 한 질병의 경우에 대하여 보고하고 있다. 그것은 이미 임상적으로, 알려진 어떤 질병의 범주에도 속하지 않는 이상한 증상을 나타내었고, 해부학 상으로 지금까지 알려진 모든질병의 과정과 상이한 상태임을 증명하였다.
