IPTV (Internet Protocol Television), which influenced by the country's related policy of merging tri-networks integration, business will face new opportunities and subjects under the background of tri-networks integration. Building a more reasonable safety system plays an important role for promoting the healthy development of IPTV business, and it will also be necessary and effective to introduce the information security related technologies into the IPTV business reasonably in the big trend of tri-networks integration. ©2011 Springer-Verlag Berlin Heidelberg.

After the mechanism of dlegation was introduced to the usage control authorizations, obligations, conditions (UCON ABC) model, the problems of the delegation were studied in granularity, depth, breadth and authorization recycling. Moreover, according to the subject attribute, the modes of the relationship between attributes and rights were established and a new UCON ABC model was designed with the characteristic of delegation. And the formal descriptions of two sub-model for UCON ABC with the characteristic of delegation were given. Finally, the effectiveness of the new model was proved by its application in digital resource access control, which reflected the importance of the management of delegation based on the owner in the open system environment (OSE).

Judgment matrix aggregation, as an important part of group decision-making, has been widely and deeply studied due to the universality and importance of group decision-making in the management field. For the variety of judgment matrix in group decision-making, the matrix aggregation result can be obtained by using the mode of glowworm swarm optimization. First, this paper introduces the basic principle of the glowworm swarm optimization (GSO) algorithm and gives the improved GSO algorithm to solve the matrix aggregation problems. In this approach, the consistency ratio is introduced to the objective function of the glowworm swarm optimization, thus reducing the subjectivity and information loss in the aggregation process. Then, the improved GSO algorithm is applied to the solution of the deterministic matrix and the fuzzy matrix. The method optimization can provide an effective and relatively uniform aggregation method for matrix aggregation. Finally, through comparative analysis, it is shown that the method of this paper has certain advantages in terms of adaptability, accuracy, and stability to solving the matrix aggregation problems. © 2016 Yaping Li.

Based on the specific elements in terms of process area, project, practice and relevant methodologies, which were adopted from Capability Maturity Model Integration(CMMI), this paper studied feasible appraisal program that combined the CMMI implementation cycle model into entire software process, therefore, the index system and measurement model in measuring the quality of software developing process were built and the barrier of CMMI model could only be used in enterprise CMMI certification was broken down. © 2012 ACADEMY UBLISHER.

With the pilot program of tri-networks integration been finalized and implemented , the development of domestic IPTV (Internet Protocol Television) will usher in a new policy and market environment .On this premise, it is of great practical significance to be aware clearly of the problem and its priority, encountered in the process of disseminating IPTV, and to explore appropriate solutions. Besides, because of the importance and speciality of IPTV in tri-networks integration , to explore the development of the domestic IPTV needs to take into overall consideration the policy, technology, economy and even national security, and other factors. © (2011) Trans Tech Publications.
