Error in Figures 3 and 6

In the original article [1], there was a mistake in “Figure 3. Schematic diagram of setup for shock absorption test.” as published. The labels in Figure 3 (cushion material and core material) are in the wrong order. The corrected “Figure 3. Schematic diagram of setup for shock absorption test.” appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.

In the original article, there was a mistake in “Figure 6. Maximum loads of various specimens obtained from the shock absorption tests. The values of the same letter were not significantly different (p > 0.05).” as published. The label in Figure 6 has a typing error in the first column ABC in place of BCD. The corrected “Figure 6. Maximum loads of various specimens obtained from the shock absorption tests. The values of the same letter were not significantly different (p > 0.05).” appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original article has been updated.
