Conclusion Compared with the results in 2002, the incidence rates of smoking,drug abuse,sexual intercourse,being online are higher,but the rates of accidental injuries and physical activities are lower in 2004.
In conclusions, the results are following:Firstly, PE curriculum resources are defined as the element origins of the formation of PE curriculum and the indispensable and direct condition of the implementation of PE curriculum, consisting of material PE curriculum resources and conditional PE curriculum resources.
In the second example, we obtain a proof of the Chalyh-Veselov conjecture that the Calogero-Moser system with integer parameter is algebraically integrable, using the results of Felder and Varchenko.
As an application of the results we prove a generalization of Chevalley's restriction theorem for the classical Lie algebras.
We apply these results to intersection theory on varieties with group actions, especially to Schubert calculus and its generalizations.
In this paper, we prove three types of rigidity results related to CAT(-1) spaces, namely the rigidity of the isometric actions on CAT(-1) spaces under the commensurability subgroups, the higher rank lattices and certain ergodic cocycles.
This extends the results and simplifies the proof for the classical orbit structure description of  and , which applies whenF=Z.
