Content available remote A Review on the Performance and Comfort of Stab Protection Armor
EN
Stab-protective clothing is the most important component of safety equipment and it helps to save the lives of its wearers; therefore, it is designed to resist knife, nail, or needle attacks, especially to the upper body. In this paper, the essential requirements for stab-resistant armor are investigated based on an in-depth review of previous research and prototype test results. The combination of protection and comfort in armor vests is a particularly challenging task. Review of the state of the art technology responsible for the manufacture of stab-resistant clothes has revealed that their design and development should encompass the elements of comfort, freedom of movement, permeability, absorption, evaporation, and weight reductions to ensure excellent ergonomics and high wear comfort. The design as well as the production, weight, thickness, material types and properties, and the arrangement of scales determine the level of protection and comfort offered by stab-resistant vests. Currently, the production of stab-proof gear-based 3D printing technology is evaluated, using lightweight materials (aramid) in the form of segmented scales inspired by nature. As the protection performance and wear comfort of stab-proof gear is enhanced, the willingness of security, control, transport, custom, and correction officers to wear them can be significantly increased in an endeavor to ensure that fatal injuries will decrease significantly.

Content available remote Dummy code insertion and its efforts on concealment for secure processing
EN
Technology of concealing purpose of program is needed for profitable uses of an external grid. We propose dummy code insertion technique for concealment technology. We have implemented one kind of technique of dummy code insertion on trail. Moreover we evaluate strength of concealment against malicious inspection. We explain the detail of evaluation of dummy code insertion technique in this paper.
