  • The characteristics of the coherence functions of X axial, Y axial, and RZ axial (i.e., body axis) wind forces on the Shanghai World Trade Centre - a 492 m super-tall building with section varying along height are studied via a synchronous multi-pressure measurement of the rigid model in wind tunnel simulating of the turbulent, and the corresponding mathematical expressions are proposed there from. The investigations show that the mathematical expressions of coherence functions in across-wind and torsional-wind directions can be constructed by superimposition of a modified exponential decay function and a peak function caused by turbulent flow and vortex shedding respectively, while that in along-wind direction need only be constructed by the former, similar to that of wind speed. Moreover, an inductive analysis method is proposed to summarize the fitted parameters of the wind force coherence functions of every two measurement levels of altitudes. The comparisons of the first three order generalized force spectra show that the proposed mathematical expressions accord with the experimental results well. Later, the influences of coherence functions on wind-induced dynamic responses are analyzed in detail based on the proposed mathematical expressions and the frequency-domain method of random vibration theory.

  • 공정 및 작업단위등이 다양하고 복잡한 건설산업에서 작업일보의 관리는 매우 중요하다. 그러나 건설산업 분야의 다양한 건설프로젝트 관리 시스템은 작업 및 작업시 발생하는 정보들을 효율적으로 관리하지 못할 뿐만 아니라 하수급업체와의 연계가 되지 않아 실제적으로 이용되지 못하고 있다. 이것은 하수급업체에 대한 배려 없이 원수급업체 주도로 시스템이 구축/이용되기 때문이다. 이러한 이유로 하수급업체 중심의 시스템이 발전하지 못할 뿐만 아니라 프로젝트 진행에 있어서 발생하는 작업정보의 축적에 있어 누락 및 왜곡이 발생하는 문제점이 발생하고 있다. 따라서 본 논문의 목적은 웹을 기반으로 원수급업체와 하수급업체간 원활한 작업정보 관리 시스템의 개발에 관해 연구/분석하고 모델을 제시하는데 있다.

  • Recent trends in globalization and informatization underscore the importance of logistics. As a result, there is a need for skilled and specialized logisticians. Third Party Logistics (TPL) and Supply Chain Management (SCM) require logisticians with a broad base of knowledge in areas such as multimodal transport, international trade, information technology computers, finance, operations management, etc. This study conducted a survey to find out the opinions of demanders and suppliers. The results of the surrey show that there are more skilled logisticians in the field of management, computer works in manager level and system management. The survey also found that the certificate exam, which the Ministry of Construction and Transportation started in 1997 as the "Certified Logistics Manager" exam, should have more questions in areas such as foreign languages, computers, logistics information, management skills, etc. To produce better logisticians in Korea, the government will have to invest more into their education, especially near the major ports and metropolitan areas. In addition, it is important that universities and companies work together to provide students with internship and other field-experience teaming opportunities. Logistics education centers should be built at the national level. In addition, the existing certification should be divided into two separate certifications: one for ordinary logistics, and one for international logistics. To further improve the certification system, short-answer or essay questions should be added to the second exam, and an additional certification for the highest level logisticians, a so-called "professional logisticians certificate," needs to be introduced.ntroduced.

  • The Chicago-Bermuda system has been charaterizing international aviation order sine 1940's. Bilateralism was established as 'the' way of nogotiation in exchange of traffic rights among nations thanks to the system. The system was stable until new phenomena came into the scene. The orderly development of international aviation began to be threatened by a series of technological and commercial breakthroughs in the late 60's and 70's. Also, in the field of international aviation, aspiration of the newemerging third world countries was hightened and the emergence of an unified Europe was added to it. These caused worries on bilateralism as an efficient means of negotiation. New waves of multilateral(reginal or international) approaches have been conducted. Its formal discussion is accelerated by vigorous talk on multilateral liberalization of international trade in commodities and services, i.e., the Urguay Round. In this paper, we examine historical development of bilateralism and multilateralism in a perspective of political economy; changes in the international aviation industry, merits and demerits of the two regimes on competitiveness of negotiating partners. The ways Korea can respond to new changes are presented and compared and a tentative stance she can take is proposed.
