The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.

In this study, a detailed three-dimensional head-neck (C0-C7) finite element (FE) model developed previously based on the actual geometry of a human cadaver specimen was used. Five simulation analyses were performed to investigate the kinematic responses of the head-neck complex under rear-end, front, side, rear- and front-side impacts. Under rear-end and front impacts, it was predicted that th...
