Abstract ( 595 )
By analyzing of the features of distributed denial of service(DDOS) attacks, a novel approach of detection of DDOS attacks based on host load-concurrent connection time series prediction is proposed. This method has improved the traditional anomaly detection. It predicts concurrent connection time series and adopts prediction results as normal host load estimate of next time range. So the timeliness of normal behavior description is improved; high detection accuracy and low detection latency are acquired. Two key technologies are studied: one is load prediction technology; the other is load anomaly judgment. In order to improve prediction accuracy, a novel wavelet-BP neural network model is established and in order to increase anomaly judgment accuracy, "sliding window" method is used. Experiment results show that our new method is better than traditional anomaly detection technologies.

Abstract ( 1215 )
The Huaihe River catchment, located in the east of China, is a overlapped district of three kinds of transition zone, which are south and north climate, high and low latitude, interaction between land and sea. The Huaihe River is one of 7 long rivers of the most frequent and the most serious flood disaster in the whole country. The reasons are as the follows. Firstly, this is closely related with natural geographical disadvantages. The catchment has particular geography and climate conditions. Secondly, this is directly connected with the Yellow River pirating the Huaihe River for 661 years. Lastly, the reasonless human activities enhance the flood and waterlogging disasters. The reasonless human activities make soil and water loss and fill up the riverway. Human beings also set the obstacles in the riverway. All these reduce the riverway's ability to drain the flood.

Full text: HTMLnew PDF  (291 KB)  ( 414 )
Abstract ( 545 )
Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of eukaryotic cell regulation, and MAPK has a close relationship with cardiovascular development and diseases such as cardiomyotrophy. Overexpression of hole in the COS-7 cells inhibits strongly the transcriptional activities of AP-1 and SRE. Hole functions as a inhibitor probably through its ERK D-domian in N-terminal and proline-rich region in C-terminal. The results suggest that hole might be involved in heart development through MAPK signaling pathway.

Full text: HTMLnew PDF  (456 KB)  ( 484 )
Abstract ( 598 )
Heavy metals in urban topsoil have been shown to be very useful tracers of environmental pollution because urban topsoil is the "recipients" of large amounts of heavy metals from a variety of sources including industrial wastes, vehicle emissions, coal burning waste, and other activities. Dust from the ground because of wind erosion may have toxic effects as a consequence of inhalation or ingestion by humans, particularly children, which poses major health hazard. Furthermore, any contamination of urban topsoil could cause in turn surface water/groundwater contamination because metals of the polluted topsoil tend to be more mobile than those of unpolluted ones. In this paper, we firstly probe into the connotation of carrying capacity of heavy metals in urban topsoil, analyze the mechanism and inhabiting factors of heavy metals in urban topsoil, differentiate "absolute carrying capacity" and "relative carrying capacity" and put forward the computing model of relative carrying capacity for heavy metals in urban topsoil. Secondly, the preliminary assessment index (FD) and sustainable development index (FS) are discussed. Lastly the controlling measures on the emissions of heavy metals are discussed.

Full text: HTMLnew PDF  (275 KB)  ( 360 )
Abstract ( 597 )
The system maintenance becomes more and more notable with the development of system developing and implementing technologies. Particularly, the maintenance problems of the group organization's ERP(Enterprise Resource Planning) system are more distinctive because of its complexity. Up to now, researches have been limited to relational models, maintenance problems of specific systems such as real-time systems or web-based systems, and factors related to the efficiency of maintenance activities such as maintenance men's experiences or the systems' complexity. While few concentrate on ERP systems and even few take care of the maintenance problems of group organizations' ERP system. Through investigating two large group organizations, this paper concludes the characteristics of group organizations and analyzes its factors related to maintenance efficiencies. Further more, it summarizes a relatively suitable maintenance mode for group organizations' ERP systems: the centralized maintenance with self-maintenance and multi-maintenance.

Full text: HTMLnew PDF  (279 KB)  ( 470 )
Abstract ( 621 )
Supply Chain Management (SCM) is one of the key issues, trends and needs in the current business environment. The concept of SCM emphasises co-operation and collaboration among the firms within a given supply chain. The essence of this concept is that when the firms in a supply chain collaborate, it leads to a win-win situation, i.e. all firms will benefit. The objective of this paper is to give a simple quantitative model that shows how and to what extent win-win situations can occur in a supply chain partnership environment. For this purpose, the paper models a situation where a manufacturer sells product to a retailer who in turn sells the product to the consumers. Both the manufacturer and the retailer set their own selling price. It is shown that if they set the price jointly in a partnership environment, there would be a significant improvement in total supply chain profit. Also, it is shown how the prices can be set so that the gain in profit is fairly split between the manufacturer and the retailer.
