The ergonomics investigation on the footrest could not only improve the occupant comfort of the seat, but also reduce the safety issues for the passengers.
Therefore, only two elements should be considered during the ergonomics analysis of the rear passengers: i) occupant comfort and ii) operability and safety.
In addition, the safety of the footrest should be considered besides the operability during the design.The safety issues indicate all the dangers which could potentially occurred during the use of the footrest.
It is worthy to mention that the designed structure of the footrest needs to optimize further to guarantee the structure strength and traffic safety.

The attacker monitors the traffic of B and changes its status from running to offline to bring about communication interrupt by traffic attack or modifying the configuration file.
In traditional mode, there is a set of independent security protection products on each physical machine or server as well as products such as firewall, gateway safety protection equipments and WAF deployed at the periphery.
However, new network model is used in virtualized data center, where dozens of operating systems or application programs are deployed on physical server in the form of VMs so that the hardware resources are shared and external networks can be imperceptible to the network traffic among the VMs.

It can be seen that most domestic and international scholars regard the repair problem of road network as a combinatorial optimization problem, mostly use travel time, traffic and other information to performance the assessment goal of the scheduling procedure for post-disaster road network rehabilitation, and repair time as a specific value.

Support vector machine algorithm, K-means clustering algorithm, database management traffic characteristics transform algorithm and the proposed algorithm are used respectively to make intrusion detection of multi-layer distributed and large differences database.
According to the above experimental data, it can be learned that by using this algorithm make intrusion detection of multi-layer distributed and large differences database, can greatly improve the detection rate and reduce the false alarm rate, to ensure maximum safety of database.

Zhao Ying (1999) believes that national economic security is a country's economic competitiveness, the capacity to withstand a variety of domestic and foreign interference, threats, invasion, etc., and also a country’s growing domestic and international environment for its existence and development.
Currently, nuclear power is welcomed in the international energy industry, but its accompanying negative impacts on economic security bring the country some insecurity, its disadvantages are as follows: (1) Possibility of nuclear leakage of nuclear power plants, i.e. security issues.

In some situations, the trauma caused by serious traffic accidents, falls and beat, infections and tumors etc may result in mandibular discontinuity or deformation.
This is considered beneficial for the implant’s safety.
On the contrary, this will improve the safety on a certain extent.
