مشكلة البحث :-

     ظلت رغبة الانسان في المعرفة وفهم الكون الذي يعيش فيه ، ملازمة له منذ المراحل الاولى لتطور البشرية ، فالانسان بما يتمتع به من امكانات وقدرات وطاقات كامنة استطاع عن طريق تفاعله واحتكاكه الدائم والمستمر والخلاق مع البيئة المحيطة به ان يلاحظ ، ويتخيل ويتذكر ويفكر ويخطط ويبتكر ، مستفيداً من اخطائه في التعرف عليها ، وفي زيادة قدرته على التحكم فيها وتحسينها وتطويرها ، محاولة منه لتأمين حاضره ومستقبله ( الكعبي، 2002 : 5 )

         وتعد الجغرافية احدى المواد الدراسية التي يدرسها المتعلم في المراحل الدراسية جميعها لانها ترمي الى تحقيق اهداف معينة ، منها تزويد الطلبة بالمعلومات والحقائق الجغرافية عن اقطار العالم المختلفة وما تمتاز به من موارد طبيعية وامكانيات بشرية واقتصادية واوضاع سياسية واجتماعية ، والتعرف على بعض الظواهر الطبيعية ودراستها ، كالجبال ، والسهول ، والاودية ، والمدن ، واحواض الانهار ، والصحارى ، والاقاليم المدارية وشبه المدارية ، ودراسة الطقس والمناخ ، وحركة السكان ، وتطوير المدن وتخطيطها ، وطرق النقل والمواصلات البرية والجوية والبحرية . وان الجغرافية كعلم ، يسعى الى وصف علاقة الانسان بالبيئة التي يعيش فيها ، وتطويرها وتفسيرها.

         ولكي تحتل مادة الجغرافية ، بوصفها مادة دراسية ، مركزاً متميزاً بين المواد الدراسية الاخرى وتأخذ مكانتها بين تلك المواد ، وبوصفها علماً يحتل بين فروع المواد الإنسانية الصــدارة ، ينبغي ان يركز في تدريسها ، على تزويد الطلبة ببعض المهارات والمعلومات والمفاهيم الجغرافية المختلفة .

         ان الكثير من طالبات الصف الرابع العام ، تكمن شكواهن في صعوبة تعلم بعض الموضوعات الدراسية في الجغرافية ، ومنها المفاهيم ، فنراهن لا يفهمن فهماً عميقاً ، ويحفظن دون استيعاب لمدلولات تلك المفاهيم مما يــولد لــديهن اتــجاهات سلــبية نحو التعلم ، ( زيتون ، 1994 : 8 ) .

         ويعزى هذا الضعف الى استخدام المدرسين لطرائق التدريس التقليدية في تدريس مادة الجغرافية والتي تستند الى حفظ وتلقين المعلومات والحقائق والمفاهيم دون الربط بينها ، مما دعا الى فكرة استخدام المفاهيم ( Concspts ) بوصفها عناصر لتنظيم المناهج اذ ما زالت الطرائق التقليدية القائمة على الحفظ والتلقين والاستظهار تأخذ فعلها في تدريس المفاهيم الجغرافية في مدارسنا ومعاهدنا بشكل واسع وقلة استخدام الاستراتيجيات التعليمية الحديثة .

         ان اعتماد استراتيجيات تدريس المفاهيم تجعل الطالبة تفكر تفكيراً عقلياً مترابطاً منطقياً محللاً للاسباب والعلاقات التي تربط بينها وبين النتائج ضمن اطار مفاهيمي يجعل التعلم اكثر فاعلية وثباتاً  ( القاعود ، 1990 : 268 )  ( شحاته ، 2001 : 236 ) . لذا كان هذا البحث محاولة للتعرف على الطرائق والاساليب الفضلى التي يمكن استعمالها لعلاج صعوبة تعلم المفاهيم الجغرافية لدى طالبات الصف الرابع العام والحد منها وذلك بالتعرف على اثر استخدام استراتيجيتي جانيه وميرل تينسون في اكتساب المفاهيم الجغرافية والاحتفاظ بها لدى الطالبات .

Improving the efficiency and security of passport control processes at airports by using the R-CNN object detection model
...Show More Authors

The use of real-time machine learning to optimize passport control procedures at airports can greatly improve both the efficiency and security of the processes. To automate and optimize these procedures, AI algorithms such as character recognition, facial recognition, predictive algorithms and automatic data processing can be implemented. The proposed method is to use the R-CNN object detection model to detect passport objects in real-time images collected by passport control cameras. This paper describes the step-by-step process of the proposed approach, which includes pre-processing, training and testing the R-CNN model, integrating it into the passport control system, and evaluating its accuracy and speed for efficient passenger flow

The Effect Of Optimizers On The Generalizability Additive Neural Attention For Customer Support Twitter Dataset In Chatbot Application
...Show More Authors

When optimizing the performance of neural network-based chatbots, determining the optimizer is one of the most important aspects. Optimizers primarily control the adjustment of model parameters such as weight and bias to minimize a loss function during training. Adaptive optimizers such as ADAM have become a standard choice and are widely used for their invariant parameter updates' magnitudes concerning gradient scale variations, but often pose generalization problems. Alternatively, Stochastic Gradient Descent (SGD) with Momentum and the extension of ADAM, the ADAMW, offers several advantages. This study aims to compare and examine the effects of these optimizers on the chatbot CST dataset. The effectiveness of each optimizer is evaluat

Random Number Generation for Quantum Key Distribution Systems Based on Shot-Noise Fluctuations in a P-I-N Photodiode
...Show More Authors

A simple setup of random number generator is proposed. The random number generation is based on the shot-noise fluctuations in a p-i-n photodiode. These fluctuations that are defined as shot noise are based on a stationary random process whose statistical properties reflect Poisson statistics associated with photon streams. It has its origin in the quantum nature of light and it is related to vacuum fluctuations. Two photodiodes were used and their shot noise fluctuations were subtracted. The difference was applied to a comparator to obtain the random sequence.
