Recently, as change in global logistics environment, various issues have been presenting. These issues are including the pursuit of low cost-high added value, the realization of sustainable logistics system, the protection of environment, and the development of ubiquitous techniques. To cope with these environment changes and improve the national logistics system, the government have carried out various logistics policies and pushed ahead development of national logistics information network. But still, from a view-point of national logistics, there are several inefficient elements such as information connection and utilization, code/data standardization. In this paper, the survey result of global logistics environment change, logistics policy of a developed countries, domestic logistics policy and information system status will be presented. And from these status, suggestive points are mentioned. Finally the status of railway logistics information and future developments are presented.

국가의 경쟁력은 급변하는 환경에 적극적이고 빠르게 대처해야만 제고될 수 있다. 최근 고부가가치 창출, 지구온난화, 보안 안전 등의 글로벌 환경변화에 따라 교통 및 물류체계 효율성은 국가의 중요 이슈 중 하나가 되었다. 정부에서는 물류발전을 위하여 다양한 정책 및 물류정보망사업을 추진해 왔으나 국내 물류체계의 비효율성 문제는 여전히 거론되고 있다. 이러한 시점에서 국가물류체계의 발전적 개선을 위해서는 최근 세계 환경변화와 각국의 물류정책 및 정보화 추진현황 분석이 필수적이다. 본 논문에서는 글로벌 물류환경의 변화, 물류선진국들의 물류정책을 살펴보고, 국내 물류정책의 과거와 현재, 그리고 물류정보화 현황을 소개한다. 마지막으로 향후 발전 방향 설정을 위한 시사점을 요약 제시하고자 한다.

Experimental program was conducted for hydration heat evaluation of concrete using strontium based phase change material (PCM). Adiabatic temperature rise test was investigated for four days. In results, concrete with strontium based PCM has about 20 percent lower hydration heat than ordinary one.

This paper describes the analysis results of coupling beams using steel fiber reinforced concrete for comparison with measure behaviors. Analysis is performed by the finite element analysis program, Vector 2. The results show possibility that relieve complex detail of diagonally reinforced coupling beam.
