As XML (eXtensible Markup Language) is becoming a standard widely applied in data representation and data exchange in web service. In this paper, we propose a novel approach to type-ahead keyword search in XML data, call TakeXIR. The IR-style approach basically utilizes the statistics of underlying XML data to address the following challenges in XML IR system: (1) Identify the user search intention, i.e. identify the keywords to express user interests and identify nodes user wants to search for and search via. (2) Resolve keyword ambiguity problems: synonyms and polysemy exist in natural language, and a keyword can appear as the text values or tag value of different XML node and carry different meanings.

This paper analyzes the curriculum referred to the software engineering undergraduate programs of 31 software schools in the 36 national model schools of software engineering (NMSSE) and analyzes the distribution of the courses. The result shows that the core courses offered by NMSSE cover the core courses released by the teaching guidance committee of computer science and technology of higher school under the Ministry of Education (TGC) and the optional courses are not consistent in the programs of NMSSE. The analysis result can be severed as a resource for improving programs and changing the curriculum in software engineering at the undergraduate level. Also it can provide the references for revising the professional norms.

The quality and safety of pharmacy, which have become essential for the lives of the residents, directly concerns people’s health and security. The pharmacy logistics is still at the starting stage and exists a lot of problems at present in our country, so it would affect the management and monitoring of the pharmacy quality, bringing the security menace. The first section of this paper analyses the characteristics of radio frequency identification (short for RFID) technology and the pharmacy logistics system. Then RFID technology is introduced into the Pharmacy Logistics System, that is to expound the application of RFID in the pharmacy logistics system; the service level of the pharmacy logistics system would be upgraded, and the supervision of the pharmacy would be strengthened.

This paper introduce the difference between single-cast and multicast briefly, and analysis the method of multicast and their shortcomings in the traditional network system and in H.323 system. The article discusses how to implement multicast in SIP system particularly, and separately describes route of single-cast and multicast in SIP system in detail.

The economic and social development is not only in demand of job hunters who fit in with certain positions but also needs badly the job creators who develop new job opportunities through setting up their own business. The popularization of higher education has put forward new requirements on traditional application talents. According to this, to carry out the entrepreneurial education in the universities becomes a proposition of the current era. Under the influence of entrepreneurship education tide in foreign and domestic universities, how to effectively carry out entrepreneurial education, especially how the choice of entrepreneurial education mode can embody the pertinence, adaptability, uniqueness and effectiveness becomes a worth exploring topic for the local universities. According to the investigation, an elaborative exposition follows.

Nowadays, more and more abrupt environmental pollution accidents have occurred in counties of China and seriously influenced the ecological security. It is important to make systematic studies on the occurrence of abrupt environmental pollution accidents in counties. Limited researches have been made on it in China, and it is almost impossible to make early warning and emergency management in time on abrupt environmental pollution accidents in counties. This paper established an efficient emergency management system on abrupt environmental pollution accidents in counties of China based on the technology of Geographic Information System (GIS). The framework, the design of its database and the functions of its modules were discussed and an example was described to show the practical use of the system. This system will support the establishment of emergency response and prevention system on abrupt environmental pollution accidents in counties of China

The engineering graphics is an old course with comparatively fixed content, but the teaching system should couple with the development of modern society. The new technique should be led into the course in time, so as to make the course develop vigorously. With the wide application of the Pro/Engineer which is a three-dimensional parameter software, introducing it into the course is very necessary. This article introduces the application of Pro/Engineer in the teaching of the Aggregation, puts forward the new idea of the characteristic constitution of the Aggregation, solves inadequate space imagination and enhances the association with the course such as machine design in the aspect of the constitution and expression technology of the machine, and well trains students’ creative design ability on the term of earlier period.

In the online test database system, a major issue is how to input the questions with formulas and pictures to the test database, while maintaining the format of test questions in order to support the printing layout. In this paper, a test database system supporting the formulas and pictures stored is designed and implemented. Based on this database system, an automatic generation system for test paper is achieved based on improved genetic algorithm. The J2EE technology is used to develop the online system. The system has friendly interface and it is easy to be operated. This system can support multidisciplinary test database and it can be customized according to different chapters and sections. The experiments show it is a useful online test database system and automatic generation system for testing papers.

In recent years, with the vocational college enrollment expanding, vocational education in China has accounted for half of higher education, and becomes another path to university. Higher single recruit students are different form each other in every aspect, which produces many problems. This paper listed main problems facing by the students during university life, and analyzed them by social psychology as well as proposed corresponding measures and recommendations.

College English teaching in China is an essential part of the whole education system, but there have been some problems that students have been undergoing with low efficiency and instrumental motivation, and that their language input is confined in what teachers taught. In order to solve the problems, this article designs a test and collects data to check the effectiveness of the task-based approach within the Internet-assisted multimedia in college English teaching. The results show that Linguistic form was analyzed and practiced with task-based approach which may help the learners notice the linguistic problems and try out new language forms and structures, and that Internet-assisted multimedia has been effective in intriguing learners' interests and greatly enhanced their self-esteem.
