The building of social resilience in Sichuan after the Wenchuan earthquake: A perspective of the socio-government interactions.

In November 2007, China implemented its Emergency Response Law to ensure national unified leadership and collaboration when responding to emergencies. In recent years, China's main focuses for enhancing disaster management have included emergency preparation, emergency management, and legal system mechanisms. However, its well-designed management system faced a great challenge during the Wenchuan earthquake in 2008.

Highly precise optical model for simulating light guide plate using LED light source.

In this paper, a method is proposed for highly precisely simulating the optical behavior of a light guide plate, which has microstructures of rough texture and rugged edges thereon. By adopting the 'equivalent medium-immersed measurement' to establish precise optical characteristic of the light guide plate, the simulated results of luminance distribution are much accordant with experimental measurement. This method will be useful in luminance uniformity evaluation and hot-spot check in advance, and it will greatly contribute to save time and cost of product development.
