Organizations relying on Information Technology for their business processes have to employ various Security Mechanisms (Authentication, Authorization, Hashing, Encryption etc) to achieve their organizational security objectives of data confidentiality, integrity and availability. These security mechanisms except from their intended role of increased security level for this organization may also affect other systems outside the organization in a positive or negative manner called externalities. Externalities emerge in several ways i. e. direct cost, direct benefit, indirect cost and indirect benefit. Organizations barely consider positive externalities although they can be beneficial and the negative externalities that could create vulnerabilities are simply ignored. In this paper, we will present an infrastructure to streamline information security externalities that appear dynamically for an organization.

Task-based language teaching, as a learner-centered and humanistic way of teaching, involves the learners in performing tasks. Learners' needs analysis, which acts as the principal part in language teaching, will influence the curriculum design, teaching process, teaching methodology and teaching outcomes and elicit relative pedagogical implications.

According to the deformation trend of the plasmodium, the paper utilizes the concept of equal dimension and new information in grey theory to train BP network, sets up equal-dimension and new information model that can fully reflect the law of deformation, and carries on real deformation prediction with this model. Meanwhile, the text utilizes GM (1,1) model of grey theory to predict the plasmodium. By comparing the prediction of the two methods, it draws the conclusion: the equal dimension and new information model is suitable for long data prediction of array and the precision of GM(1,1) model is relatively high.

All the current public-key cryptosystems will become insecure when size of a quantum register is sufficient. An Authenticated key agreement protocols, which is against the attack of quantum computer, is proposed. The strength of the proposed protocol is based on the problem of searching for an isogeny between elliptic curves. The time complexity for solving this problem is exponential, and the problem seems to be hard for solving with a quantum computer. The proposed protocol can provide the security properties known session key security, forward security, resistance to key-compromise impersonation attack and to unknown key-share attack, key control.

The prototyping is to realize an original model quickly according to the communication between users and developers to improve the model quality and decrease the faults. According to analyzing the basic characteristics of the mining recycling economy, a spatial decision support system (SDSS) development strategy by using the prototyping is proposed to integrate the technologies of the rapid prototyping, ComGIS skills and DSS. A SDSS of mining recycling economy in Qiandongnan is designed as an example using prototyping as its main method, the basic frame has been finished, and the design of its function models and model base also defined.

Personalized recommendation in an e-learning system can actively introduce useful learning resources for learners. It is a “push” mechanism in contrast to the “pull” way like Web searching. At the same time it is also a very efficient way especially when users can not describe their needs exactly. This paper put forward an approach to recommend right learning resources for users with different learning needs by hybrid filtering method. Learning resources are organized by learning topics through text analysis. Users with similar learning interests are found out to form different common interest groups by user behavior tracing and recording. Then, two-level user profiles are built based on common interest group detection and text analysis. At last, learning resources are introduced to users according to user profiles by collaborative filtering and content-based filtering respectively. A time factor is also introduced into the building of user profiles, which makes user profiles adapt to user’s interest shifting.

Chromosome segmentation affects the performance of the chromosome automatic analysis systems. Watershed algorithm is a widely used segmentation method. Applying it to segment chromosome images can overcome the difficulty caused by overlapping chromosomes. But the vice of the algorithm is its over-segmentation results. An algorithm based on watershed was presented in this paper. The overlapping chromosome images were obtained by a series of pretreatments. Then the distance transform was used to treat these images. The results of the transformation were used as input images for the watershed algorithm. The experiment proved that this algorithm can segment the overlapping chromosomes successfully.
