Abstract: For the Group Decision Support System (GDSS), the problems of the communication barriers are presented in this paper, and the elimination of the influence of individual adaptive attitude is analyzed and studied on group decision. Moreover, a mode of communication with the purpose of reaching an effective consensus is proposed. Additionally, the technical support and network infrastructure to solve the problem are provided in the systematic design of GDSS.

Abstract: Hydrodynamics based numerical model is an effective way to simulate the movement of flood and its result can be visualized by many post-processing softwares. However, most of these tools are available only as local applications. This both limits the accessibility of the software to a specific machine and collaborative research. In this paper, we introduce a four-layer architecture for web-based visualization of numerical model. The application uses VTK(Visualization Toolkit) to render the numerical result and then the VRML standard is used to provide dynamic features over the web. By developing web-based visualization tools, it is possible for users to access the situation of flood wherever the internet is available, and can largely promotes the public services such as flood risk management.

Abstract: With the development of WebGIS, it plays a more and more important role in government and enterprises. The effective way to access and control spatial data, because of relating to the security and business secrets of government and enterprises, becomes an urgent concern for them. Now, RBAC (Role Based Access Control) can be a valid method to access and control uniform resource, but it is lack of flexibility and real-time ability to control spatial data in WebGIS. For that, this paper proposes G-RBAC model based on RBAC model to enhance the flexibility and real-time ability to access spatial data.

Abstract: Through adopting probability and statistics model in the process of computing shortest distance, partition strategy can solve the low efficiency of traditional algorithm. Theoretically the time complexity could be reduced to O(N). In this article main algorithms are provided and the factors of affecting algorithms efficiency are also discussed. Finally put forward some applications of the algorithms in our life and research.

Abstract: To improve medical students’ understanding of human body morphology and stimulate their interest in learning with the nine human systems as the center anatomy, histology and embryology, pathology as the whole. Founder Author Tool was used to make human morphological thinking mode software applied in teaching. Through peer review, student survey and feedback on teaching results, the course ware was evaluated. Founder Author Tool used to make human morphological thinking mode soft ware could obtain good results in teaching and won favorable feedback from students. This new thinking mode software used in teaching helps greatly in bettering medical students’ understanding of human body morphology, stimulating their interest in learning and improving the learning efficiency.

Abstract: Multimedia and the Internet as a representative of the modern information technology put society as a whole is an organic whole repeatedly, the wisdom of the ages and all mankind will converge at worldwide covered giant network system. It is a wise networking, not only have extended the human brain thinking activity, but also created a human brain which is developing rapidly every hour and every minute, make it become a mankind can share the precious resources. More importantly, the information is changing our way of life, sense of living, learning method and thinking mode.

Abstract: Because the present science and technology development, clinical epidemic studies and inspection of experiment teaching improved, the emergence of a new model of experimental teaching, such as network visual media experiment, the experimental process with virtual laboratory way vivid show in the student, arouse the students' interest in learning, deepened the student to experiment of understanding. His paper mainly introduced how to use Windows Moviemaker software product virtual laboratory introduction Clinical immunology and test experimental teaching form obsolete, the enthusiasm of students to do the experiments is not high; the experimental teaching means of a single, involved the experiment content is not much, lack the overall ensign, the affect of test is not well; the experiment lesson is insufficient; laboratory equipment is insufficient, cannot satisfy the needs of the students. Now, in view of the above problems there is a new model of experimental teaching, such as network visual media experiment, the experimental process with virtual laboratory way vivid mage display in the student and arouse the students' interest in learning, deepened the student to experiment of understanding[1,2]. This paper mainly introduced how to use Windows Moviemaker software production virtual laboratory.

Abstract: The aim would clinical immunology and inspection content and network. Is connected, enable medical students more convenient and more vividly understanding, then learning this course, motivate the study interest. Methods: Using webpage making software FrontPage 2003 and animation software (flash and photo editing software (Photoshop) vivid teaching content on the website will be displayed, and the form of peer appraisal, students through questionnaire survey of software evaluating. Results: Using FrontPage software will book knowledge into a web page making mode of learning in the student to study independently receive a good result, also added "online self-test" edition piece, more effective inspection study effect, student feedback is good. Conclusion: This study pattern application of student learning, for students to deepen the understanding of this course and improve the learning efficiency, arouse the interest in learning has very good effect.

Abstract: The paper would put the content of oral histological pathology and the network together, learning this course more convenient and visualize, initiating the interest of study. Using web pages (flash) and photo editing software (Photoshop) make teaching content vividly and as questionnaire to evaluate effect evaluation. Through digital course of study, the feedback is better, achievement is obviously improved. Digital learning mode applications have a good effect to students.

Abstract: The one-dimensional feature-separability model concerning the feature-separability issue of radar emitter signals is proposed based on the probability theory and statistical theory, to evaluate the deinterleaving and recognition capability of extracted features. The proposed method is applied to analyze convention features of radar emitter signals. The theoretical analysis and experimental results show that the proposed model offers a new way to analyze the validity of extracted features, and is valid in both the original feature space and linear-transformed feature space.
