the most important strategy to modify high risk behavior, to prevent traffic accident and decrease death is effective education. it is necessary to have systematic steps with scientific background to educate effectively. the health educator has essential role in every education program; therefore the first question to ask is who should educate? the next in an education for reduce traffic accide...

With the decreasing audience of classical music performance, this research aims to develop a performance-enhancement system, called AIDA, to help classical performers better communicating with their audiences. With three procedures Input-Processing-Output, AIDA system can sense and analyze the body information of performers and further reflect it onto the responsive skin. Thus abstract and inta...

Futurists build scenarios for clients and are concerned with effectively communicating them. Stories provide frameworks and aim to engage audiences with entertainment techniques that include more than rational thinking and analysis, by exploring alternative futures involving characters and events as individuals deal with issues brought about by a new situation. Stories work at multiple levels i...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

Typical separation of component interfaces from their implementations plays at least one important role in software development. The separation makes it possible to develop multiple concrete components that are syntactically compatible with the same interface, and the compatibility is compiler-checkable. The \plug-compatibility" of multiple implementations for a single interface greatly augment...

The construction industry generates a considerable amount of waste. Faced with this undesirable situation, the ready-mix concrete sector, in particular, has invested energy and resources into reusing its own waste in its production process as it works towards the goal of more sustainable construction. This study examines the feasibility of incorporating two types of concrete waste, which curren...
