For millennia, adults have told children stories not only to entertain but also to impart important moral lessons to promote prosocial behaviors. Many such stories contain anthropomorphized animals because it is believed that children learn from anthropomorphic stories as effectively, if not better than, from stories with human characters, and thus are more inclined to act according to the mora...

Ductile design and detailing provisions were revised in 2016 by the Bureau of Indian Standards. It introduced Strong Column Weak Beam Provision (SCWB) for beam-column joint. In this paper, an attempt is done to investigate influence SCWB provision on Longitudinal Rebar Quantity (LRQ) typical columns i.e. Corner Column, Edge Middle seismic Zones III, IV, V six-story buildings. Story-wise variati...

This study investigates the variance and invariance in speech rate as a reflection of conceptual planning and cognitive rhythm. A four-frame comic strip was used to elicit speech and low-pass smoothing was done afterwards to filter out high frequency noise. Results showed that subjects invariably planned narration in terms of story plots. Variance lies in the way subjects synchronize planning a...

To study the effects of infill wall on progressive collapse resistance reinforced concrete (RC) frames with slabs, a macro finite element (FE) model was built using general purpose software OpenSees. The FE validated by existing test results. Then, subsequently used to predict potential eight-story RC frame including slabs and walls. numerical studies demonstrated that inclusion walls could inc...

Progressive collapse is a global failure for multi-story building. All stories above the removed column will consequently deform and help redistribute loads initially withstood by column. However, due to cost excessive time be involved, majority of existing experimental researches regarding progressive rely on single-story beam-column substructures or sub-assemblages. To date, how use results f...

Top-and-seat angle connections are a conventional type of steel moment connection. However, their capacity in accommodating columns loss is rarely studied. In this study, five multistory subframes using top-and-seat were fabricated and tested to investigate performance while subjected various column-removal scenarios, including: (1) middle column loss, (2) penultimate (3) corner loss. Moreover,...

This column recounts the evolution of AI research in Korea. I tell a story of agents, that is, humans and machines, that shaped the AI landscape. I sketch the formation and transformation of the AI communities from the 1980s to 2010s. The whole story consists of five periods: settlement, exploration, diversification, unification, and growth. I also describe recent activities in AI, along with g...

We propose a novel sensor system for monitoring the structural health of a building. The system optically measures the relative-story displacement during earthquakes for detecting any deformations of building elements. The sensor unit is composed of three position sensitive detectors (PSDs) and lenses capable of measuring the relative-story displacement precisely, even if the PSD unit was incli...
