WMSD occurs by accumulating the visible position and movements. Therefore, it is easier to prevent WMSD from occurring than other diseases when each employee is aware of the factors which cause WMSD. Hence, We need to develop exercise remedy, which can be done without using any exercise equipments and regardless places. The exercise prescription for those for LBP was to do the upper body exercise remedy twice in the morning and another twice in the afternoon and the spinal exercise remedy and the lower body exercise remedy once in the morning and once in the afternoon. We measured their maximum muscular strength every second week using a fitness machine so that we could compare the differences of the muscular strength of the test group and the comparison group. Therefore this research presented the fact that the exercise remedy is effective to prevent and cure LBP through a scientific test. And it confirmed that the exercise remedy by the Ergonomic exercise prescriptions is effective on LBP.

Wilbrink 본뜨기에서 모우드 라킹 현상과 소모적 궤적의 두 경우에 대한 일반화차원 D 하(n)을 수치 해석적으로 계산하였다. 투닝변수 z=0.03, 소모변수 b=0.9, k 하(d)=0.272313668의 값으로 주어진 소모적 Wilbrink 본뜨기에서 모우드 라킹현상의 경우에는 n～20일 때 D 하(-20) =0.924202의 값을 갖으며, 소모적궤적에서는 D 하(-20) =0.63292와 D 하(+20) =1.89877의 값으로 주어진다. 이때의 값들은 n→∞감에 따라 Circle 본뜨기의 D 하(±∞) 값들과 근사적으로 일치한다.
