The article discussed safety benefits and studied safety models in geological engineering from the point of view that safety increase output and decrease loss The authors further detailed the method of calculating safety increase benefits, which is very helpful for geological engineering corporations to calculate their economic benefit

The Design and Implementation of Universal Security Enhancement Technology;

So,those security enhancement technologies provide the perfect protection with mass data during the course of disaster tolerance.

It has always been on the layer of sensibility that people recognize the safety value,the paper gives a concise analysis on the foundation of it existing from the viewpoint of labor value and avail value theory.

Ushering into the SPV ( Special Purpose the Vehicle) and the risk insulate mechanism regarding the foundation property based on SPV make asset - backed securitization - a financial and creative tool have special safety value that traditional money raising means doesn t have, but inventors of asset - backed securities may still face to investment risk.

To evaluate the tour safety benefit, the concept of tourists safety value was firstly proposed.

On safety threshold of agricultural water resources based on food security in Shaanxi Province;

Research on vibration safety threshold for rock under blasting excavation;

Safety Threshold of Arable Land Based on Demand of Agricultural Comprehensive Production Capacity;

In accordance with the current situation of project management in our country,introduce the concept and method about quality earned value and safety earned value under the direction of the earned value theory.

It was proposed that the dynamic sight safety threshold value is 0.
