Abstract
مشكلة الدراسة: تتلخص مشكلة الدراسة في السؤال التالي: ماهو دور مؤسسات التنشئة الاجتماعية في دعم الانتماء الوطني للطالبة السعودية في المرحلة الثانوية؟
أهمية الدراسة: المساهمة في حقل الدراسة في علم الاجتماع ومحاولة تقديم نتائج علمية قد تساعد في تصحيح التصورات النظرية, ومحاولة إثراء دراسات الانتماء  في السعودية بمحاور وأبعاد جديدة. أن الاهتمام بدعم الانتماء الوطني يعد أمراً بالغ الأهمية, لأنه يساهم في تحقيق التوافق والانسجام بين أفراد المجتمع الواحد.

In cognitive radio (CR) ad hoc networks, spectrum efficiency and energy efficiency are vitally important because spectrum availability is opportunistic in nature and mobile CR nodes usually have limited energy. Aiming to improve network throughput along with improving spectrum and energy efficiencies, this paper proposes a channel-slot aggregation diversity based slot reservation (CADSR) scheme by which each CR node can utilize multiple slots in different channels simultaneously and efficiently utilize the power control mechanism with only a single CR transceiver.

Command, control, communication, computer and intelligence (C4I) systems provide situational awareness, which contributes to the decision making process in complex operational environment. The C4I systems need real time seamless information exchange amongst its elements over a distributed network. Cognitive radio (CR) is an emerging wireless technology that can use spectrum in an entirely new and more efficient manner and offer efficient, secure, and reliable communications.
