Abstract
Silver nanoparticles (AgNPs) were prepared at 80OC and various times using the chemical reduction method. Silver nanoparticles were mixed with rhodamine B (RhB) and blended with polyacrylic acid (PAA) to enhance the fluorescence spectra. The effects of preparation times on the surface plasmon resonance (SPR) were studied using UV-Vis spectroscopy. TEM measurements of the samples synthesized at 1, and 3 min confirmed the formation of AgNPs with an average size of 13 nm and 19 nm. In addition, the FTIR data showed that the bands that appeared at 1683 cm-1 and 1243 cm-1 of PAA were changed after mixing polyacrylic acid (PAA) with AgNPs/RhB due to the interaction between AgNPs and PAA through the C=O and C-O functional groups. The new high-intensity band at 560 nm and low at 408 in the UV-visible measurements of PAA were identified by RhB and AgNPs. The crystallization of PAA-doped by (RhB/AgNPs) was determined by X-ray diffraction. Fluorescence measurements from PAA blended indicated an emission band appeared between 587 nm and 440 nm for RhB, AgNPs with 13 nm and 19 nm, respectively. Peaks emission has a wavelength higher than the exciting wavelength, indicating the electronic transition from surface plasmon resonance of the nanoparticles and π-π* from RhB to PAA. PAA blended by AgNPs/RhB enhances the fluorescence spectra of the PAA.

Abstract
Obtaining accurate information for maximizing the profits from stock market investments is complex due to several factors, one of them being the price of stocks during recent years. Artificial Neural Networks (ANNs) are widely used in the aspect of prediction for decision-making. In the case of the Stock market in Saudi Arabia, there is a lack of tools and research related to predicting Stock market activity using Radial Basis Function Neural Networks (RBFNNs). The aim of this project is to provide stock market investors with a viable system to help them find promising opportunities for success in the Saudi Market exchange. The adopted method is based on the RBFNN as it is effective in small to medium datasets; moreover, it can also be used for large non-linear datasets. Performance is further improved through optimizing the hyperparameters within the RBFNN. Accordingly, our results showed that the RBFNN algorithm predicts activity of the Saudi stock market better than ANN algorithm and linear regression. So, the value of RMSE was predicted. At 84% the MSE value was predicted at 71%, and the MAE value was predicted at 58%, RBFNN proved to be equally effective on the real data set, producing better results compared with ANN and linear regression, where the RMSE was chosen for comparison between models.

سوق العمل في المملكة العربية السعودية
جاءت الدراسة تحت عنوان سوق العمل في المملكة العربية السعودية بمنطقة المدينة المنورة، حيث تدور مشكلة البحث حول مسألة توطين الوظائف داخل سوق العمل السعودي أو ما يدعى بالسعودة، حيث نجد أن العمالة الأجنبية “الوافدة” تستحوذ على غالبية الوظائف داخل سوق العمل السعودي وخاصة في القطاع الخاص، وفي الوقت نفسه، لا يكون جميع الوافدين مستعدين أو قادرين على التكيف مع محيطهم المجتمعي والثقافي في المملكة، وبالتالي تتضح مشكلة الدراسة في الإجابة عن سؤال رئيسي مفاداه: ما هو تأثير توطين الوظائف “السعودة” على سوق العمل المحلي في المملكة العربية السعودية؟

A MODEL FOR THE IMPLEMENTATION OF CLOUD ENTERPRISE RESOURCE PLANNING SYSTEM IN KINGDOM OF SAUDI ARABIA UNIVERSITIES
In light of the developments and changes that the world is witnessing in various fields, and due to the modern management methods, that companies use, information technology (IT) has become an essential part in the companies that rely on their work. Cloud Enterprise Resource Planning (ERP) systems are one of the most prominent technologies that companies use to achieve excellence and compete with each other, which enables them to outperform their competitors and achieve a competitive advantage. Despite the importance and effectiveness of cloud ERP systems, there are many challenges and obstacles for users of cloud ERP systems that limit their implementation in many fields; the educational field in universities is considered one of the most prominent of these fields. In light of this, the study aims to address these obstacles and challenges by developing a proposed model for implementing cloud ERP systems in universities of the Kingdom of Saudi Arabia. This will be done through the use of a quantitative method, a questionnaire tool based on the five-point Likert scale will be employed, which includes a number of axes related to the subject of the study. The questionnaire will be distributed to employees and administrators (unit of analysis) working in three Saudi universities that have a great influence on the process of developing cloud ERP systems in the universities of the Kingdom of Saudi Arabia. The expected outcome of this study is to address the challenges faced by users of cloud ERP systems in universities. In addition to discussing many factors that affect the implementation or failure of the implementation of cloud ERP in Saudi universities. In addition, provide a proposed model for effectively implementing a cloud ERP system in universities in the Kingdom of Saudi Arabia.

Abstract
The study’s goal was to find out how clinical information affected the radiology report’s correctness, timeliness, reporting confidence, and clinical significance. Methods: Several research investigating the relationship between what patients tell their radiologist and the report they get back were compiled into one comprehensive evaluation. Through a thorough search of electronic resources, relevant studies were discovered (PubMed, Scopus and EMBASE). Pre-determined criteria were used to narrow down the pool of potential studies. It was decided to use the JBI Critical Appraisal Checklist for Quasi-Experimental Studies to assess the study’s methodological quality. Narrative was used to synthesise the findings. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria (PRISMA).result : The radiology report is the major source of value created by radiologists in the course of their work. Using this report, we can share important information with our referral sources while also setting the course for future research and management. Traditionally, this was done through the use of written reports of various quality. PACS/RIS and virtual reality have made a big impact on the way we do our jobs. Direct communication between referring physicians and radiologists is no longer necessary because to these innovations, which have both sped up the production of reports and communicated those results to them. We need to work harder to make our reports better so that they can be used to help patients in the future.
مؤشرات التنمية الاجتماعية في المملكة العربية السعودية في ضوء رؤيه
جاءت هذه الدراسة للكشف عن مؤشرات التنمية الاجتماعية في المملكة العربية السعودية في ضوء رؤيه2030م، هدفت الدراسة إلى معرفه مستوى التقدم والتنمية الاجتماعية في المملكة العربية السعودية وذلك وفقاً للمؤشرات الدولية للتنمية الاجتماعية بما يتوافق مع رؤية2030م ،وتبين أن المملكة العربية السعودية حققت ازدهاراً وتقدماً ملحوظاً في جميع مجالات التنمية الاجتماعية ، غير أن حجم ما تحقق من التنمية على أرض الواقع لا يتفق مع ما حملته تلك الخطط من أهداف، الأمر الذي تطلب وضع خطط تنموية في ضوء رؤية 2030 م لدفع عجلة التنمية والسير على خطى ثابتة، وقد استخدمت الدراسة المنهج الوصفي والمدخل التاريخي. توصلت الدراسة إلى عدد من الاستنتاجات أبرزها: زيادة المتوسط العمري للفرد في المملكة العربية السعودية عما كان عليه في الماضي، محاربة الأمية في المجتمع نتج عنها انخفاض بشكل كبير خلال سنوات محدودة، دعم المنشآت المتوسطة والصغيرة وتمكين عمل المرأة. وأوصت بجملة من التوصيات: الحفاظ على المكاسب التي حققتها التنمية الاجتماعية، معالجة جوانب القصور بما يتوافق مع رؤية2030م.
