Generally, the management criteria by monitoring items applied to the bridge management is decided through the intuition of the based on the empirical data without any professional and systematic background. In this study, the span deflection is selected among the bridge monitoring items and verify the appropriate management criteria in the case of...

... was an accident claiming several deaths with some people missing when the highway bridge collapsed in Minneapolis, Minnesota, the U.S., on August 1, 2007 (local time) (shown in Fig. 1). Similar accidents occurred in Korea, too, when the Changseon Bridge and Seongsoo Bridge collapsed in 1992 and 1994 respectively with deaths involved. The Korean government established "Special Act for the Safety Control of Public Structures" in 1995 and, setting up "Korea Infrastructure Safety and Technology Corporation", has ...

We asked college students to make judgments about realistic moral situations presented as dilemmas (which asked for an either/or decision) vs. problems (which did not ask for such a decision) as well as when the situation explicitly included affectively salient language vs. non-affectively salient language. We report two main findings. The first is...
A controller design is presented for directly shaping the sensitivity function in the feedback control of dual-input single-output (DISO) systems. We provide special forms of discrete-time Youla-Kucera (YK) parameterization to obtain stabilizing controllers for DISO systems, and discuss concepts to achieve a reduced-complexity formulation. The prop...
Abstract: Knowledge on stocking density enables the farmer decide on the density limits that will enhance fish yield when intuition
and experience are used as guide. Twelve weeks experiment conducted in concrete tanks assessed the growth performance and
survival rate at different stocking densities of test specimens. Data analysis revealed that the...
In the so-called push dilemma, an out-of-control speed-train is about to run over five people and can only be stopped by pushing a heavy person onto the tracks. Most lay people and moral philosophers consider it morally wrong to kill the heavy person. Unger (1992, 1996), however, argued that adding irrelevant options to the push dilemma would overt...
Combinatorial filters are discrete structures for modeling and reasoning about robotic systems. Such filters are of interest not only because of the potential for reduction of the computational power needed to execute the filter, but also for the insight they can sometimes provide into the information requirements of certain robotic tasks. It is kn...

The span deflection among the monitoring items of bridge measurement system in real time is representative behaviour and important index of superstructure condition. the limit of span deflection in Standard Specifications for Highway Bridge in Korea has been applied to the method that is making the management-criteria for span deflection in bridge measurement system. But the limit concern mainly serviceability of divers. So it is difficult to find the safety factor of the limit from the viewpoint of bridge safety. This study estimated the safety factor of the limit of span-deflection in Standard Specifications for Highway Bridge in Korea from the viewpoint of bridge safety by the indoor structural test.
