We propose a novel approach called adaptive fuzzy ant-based routing (AFAR), where a group of intelligent agents (or ants) builds paths between a pair of nodes, exploring the network concurrently and exchanging obtained information to up-date the routing tables. Routing decisions can be made by the fuzzy logic technique based on local information about the current network state and the knowledge constructed by a previous set of behaviors of other agents. The fuzzy logic technique allows multiple constraints such as path delay and path utilization to be considered in a simple and intuitive way. Simulation tests show that AFAR outperforms OSPF, AntNet and ASR, three of the currently most important state-of-the-art algorithms, in terms of end-to-end delay, packet delivery, and packet drop ratio. AFAR is a promising alternative for routing of data in next generation networks.

There are 22 times as many people living with HIV in the population of drug users as in the general *** is because the injection and sexually risky behaviors prevalent in this *** multiple sexual partners and maintaining sexual networks with people who inject drugs (PWIDs),can increase the risk of contracting a sexually transmitted infection^([1]).More than 65%of all HIVrelated cases in Iran can be traced back to people who inject drugs (PWID),and the number is estimated to be between 200,000 and 230,000 in Iran *** prevention,resources allocation and monitoring require an accurate estimate of the population of people who use illicit drugs^([2]).

Trauma care system in Iran

引用

Chinese Journal of Traumatology 2011年第3期14卷 131-136页

作者： Moussa Zargar Seyed Mohammad Reza Kalantar Motamedi Mojgan Karbakhsh Seyed Mohammad Ghodsi Vafa Rahimi-movaghar Farzad Panahi Soheil Saadat ali Khaji Seyed Mahdi Davachi Sarah Ganji Mahmoud Khodabandeh Shahab Abdollahi Far Morteza Abdollahi Mohammad Reza Zarei Sina Trauma & Surgery Research Center Tehran Uni-versity of Medical Sciences Tehran Iran Shahid Beheshti University of Medical Sciences Tehran Iran Community Medicine Department and Sina Trauma Research Center Tehran University of Medical Sciences Tehran Iran Baghiatallah University of Medical Sciences TehranIran Emergency Medical Services Organization Iran

Objective： The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function. Methods： The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers. Results： Currently, various organizations are involved in prevention, management and rehabilitation of injuries, but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement, hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure （regarding staff, maintenance, financial resources）, it is not yet established in our system of trauma care. Conclusions： It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.
