“Systems neuroergonomics” (Mau, J. In: R. Wang and X. Pan, editors, Advances in Cognitive Neurodynamics (V), chapter 59, pages 431–437, Springer Science+Business Media, Singapore, 2016) showed a separation of human-body system’s functional organization from its cellular material in order to open a holistic perspective that can comprise all body functions. This was achieved with a strictly hierarchical structure in drill-down from system’s functional whole to base functional elements. Implied multi-scale functional dynamics with coherent up-scaling were mathematically described in an axiomatic way, but the daily wake/sleep dynamics cover mainly anticipated functional challenges. Here, the theory is expanded to permit “functional learning” in the sense of adjustment of functional capacities to meet higher demand. “Functional aging” as a whole-body frailty is derived from biodynamic entropy that eventually drives the living to meet its inevitable destiny, death. The ages at which frailty begins to dominate can currently be obtained only from official life tables as population averages and are different for men and women, accordingly. The objective is to develop a mathematical theory in medicine from an axiomatic approach to phenomenological biodynamics, in which cognition is viewed as an embodied activity.

“系统神经工效学”（Mau, J. In：R. Wang 和 X. Pan，编辑，认知神经动力学进展 (V)，第 59 章，第 431-437 页，Springer Science+Business Media，新加坡，2016 年）显示了分离人体系统的功能组织从其细胞材料，以打开一个可以包括所有身体功能的整体视角。这是通过从系统的功能整体向下钻取到基本功能元素的严格层次结构来实现的。具有相干放大的隐含多尺度功能动力学以公理化的方式在数学上描述，但每日唤醒/睡眠动力学主要涵盖预期的功能挑战。在这里，该理论被扩展为允许“功能学习”，即调整功能能力以满足更高的需求。“功能性衰老”是一种全身虚弱，源于生物动力熵，最终驱使生者迎接其不可避免的命运——死亡。虚弱开始占主导地位的年龄目前只能从官方生命表中作为人口平均值获得，因此男性和女性是不同的。目标是从现象学生物动力学的公理方法发展医学数学理论，其中认知被视为一种具体的活动。
