Abstract: In order to select “the best all time college coach” across both genders and all possible sports, we establish a multi-hierarchy evaluation model based on the theory of grey system. Without affecting the reliability of the results, we analyze the distribution of every index to determine the initial screening standard, narrow target range and simplify the problem. Then, we use the theory of grey system to evaluate coaches. We first normalize all indexes to make them comparable. Second, we determine a set of the best indexes as the reference vector and obtain the correlation coefficient matrix. On the issue of the weight of all indexes, we introduce the concept of dynamic weight matrix by considering the distribution and relative size of them. After that, we obtain the value of the final evaluation from the correlation coefficient matrix and dynamic weight matrix .As for the influence of time on the evaluation, we regroup the data of coaches according to the time section for five years, which results in some statistical variables, and then we draw the trend graph of them. To sum up, the number of excellent coaches of every sport is increasing over time, but the average value and standard deviation of winning percentage is decreasing. The model has the adaptability on different sports by comparison. And because the data of women coaches is insufficient, the influence of genders on the evaluation needs to be researched further.

Abstract: The enterprise practice of teachers in higher vocational colleges is adapt to the needs of the development of higher vocational education. It is an important approach to build “the double teacher” construction. Through researching the data obtained from some higher vocational college teachers' enterprise practice, the paper has done some analysis on the current overall status of the teachers in enterprise practice. We have carried on some explorations about the existing problems in three ways, such as the colleges, teachers and enterprise.

Abstract: With development of network and communication technology, cable network on university campus brings much convenience for teaching and research work. But for mobility and flexibility, it has obvious shortcoming. Wireless network can overcome these drawbacks and has been applied in university campus. In this paper, we present the advantages of wireless network and propose the design standards, construction and security measures for wireless network on university campus.

Abstract: Nationwide Fitness national fitness project is a concrete manifestation of the implementation in China is one of the material foundation and site security. The National Fitness Program is the main material carrier by which our government can practice national fitness plan. In this paper, there are future strategies for development of the National Fitness Program in urban communities in China. It is found that implementation of the National Fitness Program has greatly improved people’s exercise conditions, making it more colorful and modernized. The features and problems in practicing the National Fitness Program in urban communities were discussed and strategies were put forward for further development. Health literacy on a regular basis, so that exercise training can understand and master the scientific method, and improve exercise efficiency, reduce security risk, so that physical activity can be into people's life style behavior.
