Currently, there is no quantitative way of measuring WiMAX technology so that wireless operators can meet their design objectives. This paper outlines a set of design criteria for WiMAX and provides a decision-making aid that ranks the importance of criteria using Analytic Hierarchy Process （AHP）. This ranking should sufficiently reflect market expectations of the relative importance of various design criteria. A model integrating AHP priorities with enhanced Data Envelopment Analysis （DEA） is the basis for formulating a technological value in simple, comparable format. A case study is provided to show how this technological value is used to evaluate a three year network deployment plan. In the future, this model could be extended to WiMAX equipment suppliers for the purpose of validating performance targets of individual criteria, and enhancing supplier roadmaps for future network development.展开更多

For college students, acquiring reading comprehension ability plays an essential part in understanding cultural distinctions and communicating effectively. However, the truth is that their reading comprehension ability and language applying competence prove not very optimistic. Therefore, the Present paper gives some insight to teachers on how reading English should be taught more effectively to college students.展开更多

Methods The operators were divided into two groups, 30 persons at random in each group. One group applied Decosept and the other one applied iodine to surgical hand disinfection according to Disinfection Technology Criteria. Neutralizer was affirmed by the test of neutralizer. Results The killing rate was 99.43% in Decosept group,and 99.26% in iodine group. There was no obvious difference between the two groups. June 2003 Vol12 No2 Conclusion When the operator brushed hands strictly according to the regulations on sugical hand disinfection, there was no bacteria on the two hands and no poison and side-effect. 4 refs,2 tabs.展开更多
