Abstract: Internet attack is increasing and causing enormous economic loss in recent years. The network security literacy learning for educating students to defense Internet attack becomes more important. With the rapid development of computer and the mobile communication technology, the concept of entertainment is not new in todays Mobile Learning life and its purpose is to make the learning process more enjoyable when making people gain learning environment and resources anytime and anywhere. This paper integrates a funny computer network security education game into an iOS-based M-Learning platform which makes the learning process more fun and effective for its student end-users.

Abstract: With the rapid increase in car ownership in China, increasing pressure of road traffic and part of the large and medium-sized city's traffic congestion had become a serious social problem. This led directly to greatly reduction of the speed of vehicles, increased fuel consumption and increased environment pollution. The promotion and application of the car navigation device can help the driver rational plan and select a route to avoid the crowded roads. This is the major significance of energy saving and environmental protection. Vehicle navigation control system based on green path planning regards saving vehicle fuel consumption as a starting point, the least fuel consumption as a goal, researches and selects the vehicles path. In-car terminal as an important part of the system is of great significance. In this paper, we inquiry and analysis via the green path planning model, based on the car terminal of the green path planning for car navigation monitoring systems database construction and in-car terminals realization. This is significant for China's low-carbon economy construction.

Abstract: With the development of internet, we usually hope to recommender the possible interested products to the consumers through analyzing to the consumers history records, and obtain better sale records in fruits marketing system. collaborative filtering algorithm is widely used in Fruits Recommendation System, and item-based KNN collaborative filtering algorithm completes clustering and recommendation through analyzing the similarity of the items. Traditional item-based KNN collaborative filtering algorithm could not deal with huge scale fruits sale data effectively to complete recommendation work. In this paper, for the large scale data, we propose a distributed item-based KNN collaborative filtering algorithm based on MapReduce cloud computing platform. The experimental results show that the algorithm has a high speed-up, and a good expansibility.

Abstract: A method of four-level emergency rejuvenation for survivable system was proposed. Firstly, failure models of survivable system were formally described based on stochastic Petri nets, in which a number of measurable index parameters for rejuvenation were also given out. And then a four-level recursive emergency rejuvenation strategy was presented based on system-level, service-level, process-level and thread-level, the computing process of rejuvenation priority is also defined and the chain of rejuvenation is obtained. Eventually, the implementation process of four-level autonomous emergency rejuvenation strategy was described using stochastic Petri nets. Compared with the traditional cyclical recovery strategy, the proposed method reduced the time and costs of emergency recovery, and enhanced the recoverable elasticity of survivable system.

Abstract: Nowadays lectures are held more and more frequently in colleges and universities. The topics and categories of lectures become more and more diversified. As a result, traditional lecture system cant meet the new requirements. The implementation of Xiamen University Encyclopedia Lecture System based on Python is given. System targets, technical scheme, requirements analysis, design and implementation are introduced to provide a method to build a lecture system. It is aimed at exploring how to create a lecture system with all-sided functions such as efficiency exact lecture search and lecture application flow simplification.

Abstract: To solve the problems of semantic heterogeneity in agricultural e-commerce, improve standardization of agricultural products in agricultural e-commerce, the agricultural e-commerce is investigated from the perspective of ontology. The paper firstly introduces the concept and theory of ontology, analyzes agricultural products activities during the process of e-commerce, and evaluates the application of ontology technology in agricultural e-commerce, then develops the e-commerce standards for the agricultural products, and builds the ontology knowledge base of agricultural e-commerce, implementing the standardization of agricultural knowledge in agricultural e-commerce. The simulation results indicate that the application of ontology in the agricultural e-commerce solves the problems of traditional agricultural e-commerce, and provides sharing platform for the agricultural knowledge, contributing to the development of agricultural e-commerce.

Abstract: With extensive and thorough research on the three-tier B/S/D architecture and software development theory, we develop an elementary school online registration and allocation system using the bit-operation and template layered management technology in authorization management and implemented a three-tier management information system for Changchun city educational bureau, districts educational bureau to local elementary schools. In the allocation module, we propose an isometric random sample algorithm which is a fair and efficient allocation algorithm. Later, we discuss our in-depth analysis on the overall framework of the platform and each function module of the elementary school online registration and allocation system.

Abstract: An interactive education information administration platform based on .NET and WAP is presented. In this platform, the users can use the WAP-capable devices such as cell phones or PDA to perform the operations such as course inquiry, grade inquiry, online registration, online sign-up and information browsing anywhere anytime they want.

Abstract: For search of semantic Web services, a semantic Web services matching results ranking mechanism based on SDMM (semantic distance metric model) is proposed. The calculation of semantic similarity measure can be realized by using this three-dimensional SDMM which is for presenting the semantic relationship of objects defined in ontology, therefore, the semantic Web Service matchmaking results can be ranked in accordance with the semantic similarity measure. The approach based on SDMM significantly improves search accuracy of semantic Web service matchmaking, and enhance users experience of semantic Web services search. By a set of experiments, we demonstrate the benefits and effectiveness of our approach.

Abstract: With the advent of the Web2.0, more and more people use modern information technology in education field, make education realizes the informationization, intellectualization of new education form. Build the course practice platform is to introduce the information technology into the professional knowledge learning, providing students with fast, efficient learning resources and the environment ,at the same time improving the professional knowledge level of the students and the ability to practice and practice. Based on the news photography course, this paper discussed the necessity to establish the course practice platform and analyzed platform development and implementation process in detail.
