Besides, in general, accounting study regards ERP announcement as strategic orientation, while this paper would like to highlight the significance of non-financial information from ERP, and enhance the effeteness of accounting information. This study also assists corporations to review the efficiency of ERP before introducing, and meanwhile encourages enterprises to implement e-business. During the research, we realized that the model has the following constraints: 1. Sampling.

本论文希望能对学术界与企业界有所贡献，对于学术界而言，相关研究成果能有助于将信息科技投资的绩效评估研究触角加以延伸；另外，会计研究视ERP系统导入宣告为一种策略性导向，研究结果亦可同时强调在外部财务报表上揭露EPP系统等非财务性信息的重要性，藉以提升财务会计信息的有用性；对于企业而言，可以重新检视本身ERP系统成效，亦可提供企业在导入ERP系统前的决策参考，激励企业及早进行企业E化。

At present, there are two branches in the research of database security technology, which are secure database management system and enhancive database security system.

Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco-elastic dampers in cable-stayed bridges is investigated by joining the center difference method and the state space strategy. Both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. The space nonlinear vibration equations of the cable-damper system are derived, and anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.
