The Economic and social developments are interdependent, economic development is the prerequisite and basis for social development, and social development is purposes of the economic development. This paper selected 22 social indicators and six economic indicators which based on the relationship between society and economy, and used the theory of gray relational analysis, then buildt the socio- economic relationship model of coal industry by analysis on the social - economic relation.

Automatic generation of software test cases is studied. Within software engineering the software testing phase aims to find errors in software. However, achieving a fully tested program is a hard problem. Moreover, automation of test generation seems to be useful in order to reduce the software development cost. A scheme for the test case generation using tabu search is presented by Srivastava et. al. in 2009. In this paper, we work on their scheme. The scheme is implemented by varying slightly and comprehended by taking example for the further improvement. The study confirms that for assigning priority among the generated test cases for complex problems dynamic clustering is more suitable as compared with k-means clustering.

This paper proposes an improved web crawler algorithm to climb more useful information since the basic web crawler algorithm is low-efficiency and easy to climb useless repeated information. By the proposed algorithm, the website urls are hierarchical saved to store websites overall topology, which will make crisscross complex web URL system from a graphic structure into a tree structure. The actual website BBS experiments show that the algorithm is much better than the basic web crawler algorithm in crawling speed and download information such as the usefulness of baking. Furthermore, it provides a performing structure mode for the increment crawler algorithm.

The learning resources play an importance role in the e-learning, which refers to any learning and training method that mainly uses the internet or intranet as a method of diffusion. The VRML can provide a standardized, portable and platform-independent way to render dynamic, interactive 3D scenes across the Internet. In this paper, it is introduced a practical method of developing the virtual learning resources for the E-Learning system based on VRML, which is useful for teacher who want to develop and design the virtual learning resources according to the actual situation of learners.

Along with the rapid spread of the Internet and the advancement of education informationization, teacher development is very urgent and drawing more and more attention. This paper tries to reveal the role of the Internet in college English teacher development by conducting two questionnaires, which are respectively aimed at analyzing the use of network and the network's influence on teachers' teaching practice, development awareness. Then two variance analyses are made by dividing respondents into different age groups and different academic title groups. The author hopes that this survey can contribute to the future college English teacher professional development.
