### Influencing Factors of the Communication Elements  
Table 6 lists the communication sub-elements and their influencing factors. We discuss some of the influencing factors below. Communication elements distinguish this work from the rest of the team studies; consequently, we tried to collect the influencing factors in this element as comprehensively as possible. An example of possible relations between communication sub-elements is shown in Figure 7. \begin{table}

Table 6: The influencing factors of communication element. Figure 7: An example of possible relations between communication sub-elements. The \"communication utterances\" sub-element covers speech and its analysis, while the \"act of communication\" sub-element covers the triggers to communicate from the speaker. The \"act of communication\" is carried out by an individual (the speaker); thus, it is related to the following individual elements: \"cognitive functions\", \"communication intention\", and \"non-technical skills\". Upon noticing the need to talk, the \"communication intention\" is formed; it is processed through the \"cognitive functions\" and affected by \"non-technical skills\", before being carried out as an \"act of communication\". A \"communication intention\" can be expressed in multiple \"acts of communication\" (one-to-n relationship).
