(c) (d) Figure 3.2: The Joint Angles at Two Poses in Task#1.(a) Trunk; (b) Hips; (c) Right Shoulder; (d) Left Shoulder. The Positive and Negative Values for the Trunk, and Hips Indicate Flexion and Extension Table 3.1: All the Statistical p Values for the Two Specific Poses were Listed. T1 Represents Task#1; Trunk_Flex Represents Trunk Flexion and Extension; R_Sh_Flex Represents Right Shoulder Flexion/Extension; R_Sh_Abd Represents Right Shoulder Abduction/Adduction; L_Sh_Flex Represents Left Shoulder Flexion/Extension; L_Sh_Abd Represents Left Shoulder Abduction/Adduction. All the p Values Less than 0.05 were Bolded Table 3.2: The p Values Between Males and Females are Listed For Task#1 at Pose#1 Table 3.3: The p Values between Males and Females are Listed for Task#1 at Pose#2 © 2023 Global Journals Global Journal of Researches in Engineering Volume XxXIII Issue II Version I 7 Year 2023 ( ) G Evaluating the Risk of Injury for Aircraft Attendants using Virtual Reality and Advanced Motion Tracking System Integrated with Ergonomics Analysis Tables 3.4 and 3.5 present the results of the correlation coefficient analysis. It appears that the variable body height of the subjects has a relatively high correlation with the compressive spinal force. Additionally, the flexion/extension of the right hip is correlated with spinal forces at Pose#2. The R values for all the correlations are listed in the tables. Table 3.4: The Cross-Correlation between Variables at Pose#1 in Task#1 is Listed. T1_P1 Represents Task#1 at Pose#1; BW Represents Body Weight; BH Represents Body Height Table 3.5: The Cross-Correlation between Variables at Pose#2 in Task#1 is Listed. T1_P2 Represents Task#1 at Pose#2 b) Task#2: Lifting the Passenger Luggage Figures 3.3 and 3.4 illustrate the variables tested for significance at two specific poses. Nearly all the variables show a significant difference, except for the right and left shoulder abduction/adduction when subjects
