More than 13 years later, a very similar phenomenon was described in The Lancet, this time dubbed ‘PlayStation 2 (PS2) Thumb’ [5]; PS2 thumb was later described in ‘epidemic’ proportions in The South African Medical Journal [6] Confusingly, the term ‘Nintendinitis’ (compared to ‘Nintendonitis’) was also coined in 1990 to describe a repetitive strain-type injury affecting the wrist and elbow [7]. 
Design The materials preferred for this design are regular polymers.

These composites materials are suitably applicable for aerospace, leisure, construction, sport, packaging and automotive industries, especially for the last mentioned application according to Malkapuram, et al. [4].
All grease, wax, dirt and other foreign materials were removed from repair area.
All loose or damaged materials were cut and grinded away.

Divide this area along its length direction into two equal parts to measure deflection value of soil material in different depth.
Pave improved soil material on it, then roll and tamp from every layer.

Introduction With the continuous development of science and technology, people from all fields continuously put forward a lot of delay differential equations .
Milling has a relatively low cutting force in machining process, to ensure high machining accuracy and can obtain the advantage of high material removal rate, and therefore is widely applied in aviation, aerospace, shipbuilding, mould and auto manufacturing complicated parts[2-3].
