Five levels of maturity in e-government development process are constructed,which include network infrastructure,information serving,information interactive,information sharing and comprehensive integrating.An index system of e-government maturity is put forward,and then an e-government maturity levels evaluation method is presented,which can provide clear,detailed and efficient decision information and investment directions of e-government for decision-makers.The EGMM and its maturity evaluation method are helpful for improving the construction of e-government.展开更多

In order to find out the actual operation situations, eight pumped-storage stations in five provinces (municipality) were investigated, and analysesand calculations were carried out on their investments, benefits, capabilities ofloan-repaying etc. During the investigation and study, the types and the installedcapacities of the stations were paid close attention to, so they were made morerepresentative to reflect the present situation of pumped-storage stations inrespect of construction and operation.展开更多

First, both knowledge-intensive activities and knowledge items can be identified by the analysis of governmental processes. Secondly, the IDEF5 ontology capture method is utilized to extract concepts, terms and statements from these knowledge items, which act as a starting point for ontology refinement and validation. To describe precisely the semantics of the ontologies, the OWL language is employed in our project to formally model these e-government ontologies with the help of Prot6ge-OWL tools. Finally, a case study about applying for social security cards （SSCs） in Shanghai local government is illustrated to demonstrate the effectiveness of the presented approach.展开更多

Moreover, the fraud prevention mechanism is fragile and does not provide strong guarantees that can be necessary for flow of legal documents. Mediated signatures have been proposed as a mechanism to effectively disable signature cards. In this paper we propose further mechanisms that can be applied on top of mediated RSA, compatible with the standard format, but providing security guarantees even in the case when RSA becomes broken or the keys are compromised. The solution is immune tokleptographic attacks as only deterministic algorithms are used on user＇s side.展开更多

Because the inconvenience caused by the service performance and the inconsistency to the environmental protection policy of the lead-acid battery, the zinc-air power battery was proposed to solve the problem in this paper. The advantage and the feasibility of developing zinc-air power batteries in China have been illustrated in the paper. And, it is represented that development of electric bicycles powered by the zinc-air power battery also can accelerate this kind of battery's development in other electric vehicles, which is favorable to economic development and environmental protection.展开更多

With e-government is developed, a collaboration between employees of public administration at different levels of the natural or legal persons according to their needs. The paper presents the electronic platforms of public administration services in Poland. The analysis of e-government was conducted based on selected statistics from reports prepared by the United Nations in 2010 and 2012. The data for the European Union and Poland are summarized in the table in order of occupied places in the ranking and evaluation of e-government and e-services in Poland on the background of world and the European Union are presented in the form of graphs.展开更多
