The prediction of emergency event occupies an important position in the network public opinion. In this paper, an improved algorithm for emergency event based on statistics of word frequency is presented, which takes BBS, blog, news sites with commentary function as investigated subjects. The experiment shows it can provide the useful ideas and exploration for analysis of public opinion and early warning of mass group incidents.

This study is to determine the influence of creative thinking instruction information technology integrated into the mechanical professional subjects of vocational high schools. This research has adopted the “nonequivalent pretest — posttest control group design” in quasi-experiment design. The study instruments include: The “Torrance creative thinking ability” and questionnaire survey on the learning reactions. Such statistic methods have used the one-way analysis of covariance (ANCOVA), frequency distribution, etc. From the study results, it has been found that: 1. The students' creative thinking abilities have contributed significantly more in originality and elaboration of figural creative thinking abilities than the students in the control group. 2. The students' creative thinking abilities have contributed significantly more in the fluency, flexibility, and originality of verbal creative thinking abilities than the students in control group. 3. The students have profound experiences in the topics related to creativity and have provided positive feedbacks. 4. The teachers must establish a learning environment and study constantly in order to link the teaching methods covered in the teaching material and real life. The students' creativity has been effectively improved through evaluations throughout the entire learning process, and the products have been completed concurrently.

A novel network layer management protocol for the low-voltage power line communication (PLC) network is proposed, focusing on the dynamic network address assignment mechanism of the PLC network with a multi-master topology. The remarkable feature of the presented protocol is that it enables the equipments to claim, configure and maintain their network addresses autonomously within the PLC network. Data communications can also be performed freely without the interferences of the network management equipments. Experimental results verified its flexibility and reliability. This protocol is tailored for the PLC networks composed of various flexible and plug-and-play equipments, which make it suitable and promising in the areas of smart home and office automation, as well as the industrial networks with low data transfer rate and soft real time requirements.

Aimed to make out land use change and its spatial differences in coastal zone of Bohai sea in last 30 years. Series satellite remote sensing images obtained in 1988, 1998 and 2007 were employed to surveyed land use change integrated field surveying. Some land use index such as land use domnant type, land use dominant index and land use intensity index were created to describe main land use function, its dominance and regional land use intensity., individually. Then the land use change and its spatial differences in 1980s, 1990s and 2000s was assessment. The result as follow: Regional differences of land use and its change was more and more with land exploitation and use process carried forward. This process expressed by shrink of coastal beach and swamp, while expasion of buiding area and fish pool. And tranform of land use dominant type from coast beach, swamp and salt lake(low intensity types) in 1980s to building are, fish pool(high intensity type) in 2000s. While Land use diversity increased and dominant index of individual land use type reduced. Land use intensity index boasted famous in coastal zone of Binzhou, coastal zone of Panjin and coastal zone of Dongying. Land use construction reformed to grow regional defferences in spatially, such as agriculture zone in coast of Huludao and Yantai, fish pool zone in coast of Cangzhou, salt lake zone in coast of Weifang and Binzhou, eatarine wetland conservation zong in coast of Dongying and Panjin.

Sustainable development is the critical theme of today's society. The enormous geothermal energy is supposed as renewable resource such as wind, solar and biomass. More significantly, because of its lower emissions of greenhouse gas (CO2), geothermal energy is effective on reducing the catastrophic environmental deterioration. This overview describes the current state and utilization of geothermal energy in oilfield, China. There are many oil-producing wells, with well depth over 3km in oilfield. Moreover, it is economic and sustainable to convert the oil well valueless or abandoned to a geothermal well, which are, therefore, the innate advantages for oilfield to develop geothermal energy. Because the current tectonic stress field is extensional in the eastern sedimentary basin of China, which leads to higher geothermal gradient that is 35–45°C/km so that oilfield distributing on Songliao basin and Bohai Bay basin, such as Huabei, Liaohe, Henan, Daqing, Dagang, Shengli and Jilin, have made great achievement on utilizing geothermal energy. By exploiting the hot water underground, geothermal energy can transform into electric power effectively and make other direct utilization such as extracting heavy oil, heat tracing system, hydrotherm heating, thermal spring and irrigating.
