For safe navigation throughout the branch, a 2.30 m minimum flow depth (MFD) is required. A recovery project to improve the branch navigation was started in 1999 and completed in 2005. The project was to implement a 40 m wide navigable waterway. About 6.50 million m3 of bed materials had been removed from bottlenecks at $ 18.20 million cost. In 2003, the construction of a new lock of 150.0 m length, 17.0 m width and (1.50) m bed level was completed on Zefta Barrages (ZB) east side to meet the navigation requirements. The barrages are located at Km 119.625 downstream (D/S) El-Roda Gauge in Cairo. However, the resulting water stage (WS) D/S (ZB) during low discharges was insufficient to provide the MFD. Field studies were conducted to reveal the reasons. They found the branch flow carrying capacity had increased due to excessive dredging which caused a decline in WSs D/S (ZB). Analyzing the hydrologic and topographic conditions, two solution concepts were reached; either to raise the WS by 0.70 m or to lower the bed level of the diversion channel located D/S the new lock by 1.0 m. Therefore, this study aims to introduce solutions to overcome the problem. The solutions are to use a D/S rubber weir for raising the WS or construct a new lock within the D/S diversion channel for lowering the bed level or build new barrages with a new lock.}, keywords = {River Nile,Damietta Branch,Zefta barrages,Navigation problem,Navigation Lock}, url = {https://jesaun.journals.ekb.eg/article_111785.html}, eprint = {https://jesaun.journals.ekb.eg/article_111785_b8f90d0537c2274aa40691328ec7a487.pdf} } @article { author = {Ali, Ahmed AbdelMonteleb Mohammed}, title = {AN INTEGRATED ANALYSIS WITH LIFE CYCLE ASSESSMENT, BUILDING INFORMATION MODELING, AND ENVIRONMENTAL PERFORMANCE FOR WINDOW MATERIALS: ASSIUT UNIVERSITY HOSPITAL CLINIC AS A CASE STUDY}, journal = {JES.

This study has been carried out in a proposed project at the Assiut University campus. The LCA has been conducted by assessing materials and processes involved in manufacturing the two window frame types using the SimaPro. The LCA scope of this research covers from cradle to the gate with a designated system boundary. The network flow has been drawn to produce one kilogram of aluminum and wood; the quantities data were gathered from the BIM (using Autodesk Revit). Selecting the database is carefully picked from the Ecoinvent dataset to be closer to Egypt's manufacturing processes. Afterwards, the IMPACT 2002+ with midpoint and endpoint calculations has been used. Finally, the LCA results have been compared with the EP results (using DesignBuilder) to determine the best choice between the two materials. The integration analysis shows that the aluminum industry has higher negative environmental impacts and environmental performance than the wood industry. The total midpoint results of the two materials are found to be 29.6  for aluminum, and 7.57  the wood. Turning to the endpoint results, human health and resource depletion impacts are the most significant results. The human health scored the highest value, with 13.9  for aluminum and 3.51  for wood. A novel framework for integrating LCA, BIM, and EP for a proposed building during the early phases of a project has been conducted in this study. The presented study can be used as a model for integrating comparative analysis on other proposed projects as the LCA applications in Egypt are scarce due to the absence of a reliable database. This study has introduced a value applying an approach to select the appropriate life cycle inventory database from the Ecoinvent dataset. The research findings contribute to choosing the most suitable window frame materials with the most energy-efficient effect and the least environmental burden.

This paper presents a novel method that combines Gabor-features, feature selection and kernel selection to achieve comparable performance on smaller datasets.The paper compares different feature selection methods in this context.The problem tackled in this paper is achieving accurate face recognition with limited computational resources. By “limited" computational resources we mean low computational power (i.e. memory, CPU ops) during both system training and evaluation. Noted that we are not competing against deep learning systems in term of accuracy but we provided a middle ground between hand-coded fast feature extraction and learning based deep learning in terms of both speed and accuracy.To achieve this goal, we propose “kernel selection" as the main method to reduce the dimensionality of the classification problem faced by the final classifier in the FR system. Kernel selection is the process of eliminating less important Gabor kernels for classification while keeping the level of accuracy achievable. Kernel selection differs from traditional feature selection in measuring the value of complete kernels consisting of several features together. Because of its structured nature, Kernel selection has the advantage of eliminating the need to evaluate complete Gabor kernels reducing the computational cost of the system compared with traditional feature selection methods.}, keywords = {Kernel selection,Feature Selection,Face Recognition}, url = {https://jesaun.journals.ekb.eg/article_122413.html}, eprint = {https://jesaun.journals.ekb.eg/article_122413_f71620471914f84f2a96240da094030c.pdf} } @article { author = {Albukair, Mokhtar and Soliman, M-Emad S and Ahmed, S.M.}, title = {DESIGN AND ASSESSMENT OF A SPEED-BASED INTEGRATED ACTIVE VEHICLE CONTROLLER FOR LATERAL STABILITY}, journal = {JES.

The system integrates three commercially- available active vehicle control systems, namely, Active Front Steering (AFS), Electronic Stability Control (ESC) and Torque Vectoring System (TVS) aiming at enhancing vehicle handling and cornering stability and rollover prevention. Two different vehicle models were constructed to simulate the dynamic behavior of the system with and without the proposed integration controller, namely, a 14-DOF vehicle dynamic model with nonlinear tire characteristics and a 2DOF bicycle reference model. Last model was utilized to generate controller’s reference values of vehicle’s yaw rate and body side slip angle at a given forward speed and driver’s steering input. Simulation was carried out in the MATLAB/SIMULINK software environment. The effectiveness of the system was investigated applying five different standard cornering test maneuvers at different vehicle forward speeds of 10, 20 and 30m/s. Simulated test maneuvers are: step, J-turn, single lane change (SLC), sine with dwell, (SWD) and fishhook.Results reveal that, for stability enhancement, AFS is most effective at low vehicle speeds with declining efficacy as speed goes up. Both ESC and TVS have been found to be equally effective at moderate to high speeds. In conclusion, an integrated chassis control (ICC) strategy has been proposed that improves vehicle handling and cornering performance across the entire operating range of speed using a forward-speed-based stability criterion to allocate stability control authority and ensure smooth transition of control between the three AFS, ESC, and TVS systems.}, keywords = {Integrated Chassis Control (ICC),Active Front Steering (AFS),Electronic Stability Control (ESC),Torque Vectoring System (TVS),Fuzzy logic control (FLC)}, url = {https://jesaun.journals.ekb.eg/article_122412.html}, eprint = {https://jesaun.journals.ekb.eg/article_122412_74531abbd9a80e51f9a8998cfb002bc8.pdf} } @article { author = {Rizk, Sherein Ahmed M.E.}, title = {DEPENDENCE OF THE BOND WORK INDEX ON THE FILLING RATIO AND TEST SIEVE APERTURE}, journal = {JES.

It is the conditions of internal spaces, which require the architectural designer to consider when using modern environmental architectural technologies and treatments. This achieves compatibility with climatic variables throughout the whole year. Therefore, the research aimed to identify the applications of modern environmental technologies for building envelopes, how to achieve thermal comfort for users, and the extent to which it rationalizes energy consumed in achieving thermal comfort.

The new enclosed cities form a large, closed urban gathering within themselves, and share the same features and characteristics with different real estate value for residential units. It also monitors the differences in the formulation of the urban design (material) elements between each of the gated communities established within the new enclosed cities. The applied study was carried out through three axes: The first axis, through monitoring the extent did “Madinaty” achieved the general goals of both the state and the real estate developer while the establishment of new cities and urban communities, while mentioning the special features that distinguish "Madinaty" from other new cities. The second axis in the questionnaire addressed the owners’ views within "Madinaty" regarding the attractive elements of housing and investment in the enclosed new cities. It also monitored the material elements of urban design which affects the completion of each element of attraction. The third axis, it was through a comparative study of the owners ’opinions on the various factors (political, social, economic, architectural, and urban) to establish both" Madinaty ", and the recently held closed urban gathering" Privado ". And comparing with analysis the urban dimension represented in the material elements of urban design within each of them. The study concluded that individuals within the Egyptian society desire for social class distinction. This was the main dimension “reason” of the existence of a closed gated community within a larger one. And that urban design is part of an array of decisions that constitute urban development in new enclosed cities and allow the formulation of new urban patterns within enclosed new cities, because of its importance and impact on the social dimension, achievement of distinction and social worthiness, and on the economic dimension through rising the real estate value of the property. This is in addition to the state’s political dimension of encouraging investors to develop new enclosed cities because the high real estate value in enclosed new cities affects the newly developed cities that arise around them. ملخص البحث  من خلال الورقة البحثية تم التطرق إلى العوامل المختلفة لتواجد التجمعات العمرانية المغلقة  داخل المدن الجديدة ذات الأسوار والبوابات على أطراف القاهرة، والتي تعتبر في حد ذاتها تجمع عمراني مغلق کبير، حيث تشترک کلاً منهما في نفس المميزات والخصائص مع اختلاف القيمة العقارية للوحدات السکنية. کما تم التطرق إلى رصد اوجه الاختلاف في صياغة العناصر المادية للتصميم الحضري بين کلا من التجمعات العمرانية المغلقة المنشأة داخل المدن الجديدة ذات الأسوار. تمت الدراسة التطبيقية من خلال ثلاثة محاور، المحور الأول، تم من خلاله رصد لمدي تحقيق مدينتي للأهداف العامة لکلا من (الدولة- المطور العقاري) من إنشاء المدن والمجتمعات العمرانية الجديدة، مع ذکر المميزات الخاصة التي تتميز بها "مدينتي" عن غيرها من المدن الجديدة. وتطرق المحور الثاني لاستبيان آراء الملاک داخل مدينتي في العناصر الجاذبة للسکن والإستثمار داخل المدن الجديدة ذات الأسوار، کما تم رصد العناصر المادية للتصميم الحضري المؤثرة في تحقق کل عنصر من عناصر الجذب. اما المحور الثالث تم من خلال دراسة مقارنة لآراء الملاک عن العوامل المختلفة (سياسية، اجتماعية، اقتصادية، معمارية، عمرانية) لإقامة کلا من "مدينتي"، وما اقيم مؤخرا من تجمع عمراني مغلق "بريفادو". ومقارنة البعد العمراني المتمثل في العناصر المادية للتصميم الحضري بالتحليل والرصد داخل کل منهما. خلصت الدراسة إلى أن سعي الافراد داخل المجتمع المصري إلى التميز الطبقي الاجتماعي کان البعد الرئيسي لتواجد مجتمع عمراني مغلق داخل آخر أکبر منه. وان التصميم الحضري جزء من منظومة القرارات التي تشکل التنمية العمرانية في المدن الجديدة ذات الأسوار والمغلقة وتسمح بصياغة انماط عمرانية جديدة داخل المدن الجديدة ذات الأسوار، لما له من تأثير على البعد الاجتماعي وتحقيق التميز والوجاهة الاجتماعية، وتأثير على البعد الاقتصادي من خلال ارتفاع القيمة العقارية للممتلک. هذا إلى جانب البعد السياسي للدولة في تنمية وتشجع المستثمرين على تطوير المدن الجديدة ذات الأسوار لان ارتفاع القيمة العقارية بها يؤثر على المدن التنموية الجديدة التي تنشأ من حولها. }, keywords = {المدن الجديدة ذات الأسوار (Enclosed New Cities),تجمعات عمرانية المغلقة (Gated Communities),المجتمعات العمرانية الجديدة (New Urban Communities),التصميم الحضري (Urban Design)}, url = {https://jesaun.journals.ekb.eg/article_144337.html}, eprint = {https://jesaun.journals.ekb.eg/article_144337_877f7c85260909e899d397f328ea7327.pdf} } @article { author = {El-Samadony, Adel and Tantawy, Mohamed and Atta, Mohamed M.}, title = {Developing Framework to Optimize the Preparation of (EOT) Claims Using Integration of (LPS) and (BIM) Techniques in Construction Projects}, journal = {JES.

The importance of research depends that most of the architects works in implementation sector relative to those who work in the design sector, whether in the technical office or on the site, so it was necessary to analyze different skills and knowledge which is being taught in building and working subjects and compare it with the needs of work fields. The research problem is to measure the extent to which these courses practically affect the graduate qualifications actually required. And This is due to absence of this items in curricula or included it into optional subjects. To reach that the research divided into two parts, first collecting the information and skills related to building and working subjects from more than one local example to summarized evaluated points represent what the graduate should be learned, part two questionnaire to academic experts, architect and construction organizations which represent local field to identify target information and skills which help in real work field.by comparing between previous points the research reached suggested matrix which present an evaluating approach helping in develop educational curricula to upgrading the level of the architectural sector graduate in Egypt. Finally, applied the matrix on one of the architecture institutes in Egypt to reach the strengths and weaknesses of this model. إن قضية فقدان التواصل بين الطالب وبين طبيعة عمله بعد التخرج من أقدم القضايا المطروحة في مجال التعليم المعماري؛ وهي تعني بالربط بين المناهج التعليمية والتي من المفترض أن يکون لها تأثيراً مباشراً على تأهيله لسوق العمل وبين احتياجات سوق العمل نفسه. فالمناهج الدراسية وما تشمله من مهارات ومعارف مکتسبة سواء کانت في جامعات حکومية أو خاصة يجب أن تغطي مواصفات الخريج المطلوبة في سوق العمل المحلي والدولي لتأهيل خريجي الجامعات والمعاهد المصرية للتنافس على الوظائف المطروحة. ونظرا لأن النسبة الکبيرة من خريجي قطاع الهندسة المعمارية يعملون في مجال التنفيذ نسبة إلى من يعملون في مجال التصميم سواء إعداد الرسومات التنفيذية في المکتب الفني أو کمهندسين تنفيذ في الموقع فکان لابد من تحليل ومقارنة ما يتم تدريسه من مهارات ومعارف مختلفة في المواد المؤهلة لممارسة مهنة التنفيذ وما يحتاجه الخريج في سوق العمل ومن هنا تأتي أهمية موضوع البحث. حيث تکمن مشکلة البحث في وجود قصور في بعض المعارف والمهارات التي يجب أن يکتسبها الخريج والمطلوبة فعليا بسوق العمل ويرجع ذلک الى عدم إدراجها بالمقررات الدراسية الاجبارية أو عدم الترکيز عليها بالشکل الکافي، لذا أهتم البحث بتحديد وتصنيف النقاط الأساسية التي يحتاجها سوق العمل في صورة مصفوفة مقترحة للمساعدة في تطوير المقررات المعنية بالدراسة البحثية بهدف الارتقاء بمستوى خريج قطاع الهندسة المعمارية بمصر. وللوصول إلى ما سبق ينقسم البحث إلى جزئين الجزء الأول يتبع المنهج الاستقرائي في تجميع المعارف والمهارات من عدة أمثلة مختلفة تمثل التعليم الجامعي المصري في قطاع الهندسة المعمارية وتحديدا في مجال التصميمات التنفيذية ومن ثم مقارنتها للوصول إلى نقاط محدده تمثل المهارات المختلفة التي يکتسبها الخريج من دراستها .الجزء الثاني يتبع المنهج التحليلي الإحصائي من خلال استبيان موجه للخبراء الأکاديميين والشرکات والمکاتب المعمارية والتي تعني بمجال التنفيذ والممثلة لسوق العمل المحلي للوصول إلى النقاط المستهدفة والمطلوبة من خريج قطاع الهندسة المعمارية ليکون مؤهلاً للعمل بممارسة مهنة التنفيذ. ومن خلال مقارنة ما يتم اکتسابه من خلال المناهج الدراسية وما هو مطلوب من الخريج يصل البحث إلى مصفوفة مقترحه تمثل مدخل قياسي لتطوير المقررات محل الدراسة واتباع المنهج التجريبي على أحد الأماکن الدراسية بمصر والمعني بتطوير اللائحة والمقررات الدراسية الخاصة به للوصول لنقاط القوة والضعف بهذا النموذج.}, keywords = {Practice implementation - Work field- Architecture education- educational curricula,Knowledge and skills. ممارسة مهنة التنفيذ - سوق العمل- التعليم المعماري- المقررات الدراسية,المعارف والمهارات}, url = {https://jesaun.journals.ekb.eg/article_226633.html}, eprint = {https://jesaun.journals.ekb.eg/article_226633_dc2ca4527816cb2dbbc12b9794878d38.pdf} } @article { author = {Ahmed, Salwa}, title = {Developing a systematic framework for smart urban transformation towards sustainability: in the context of Egyptian case تطوير نموذج تصوري لأداة قائمة على نظم المعلومات الجغرافية لمراقبة وتقويم الأداء الحضري لتمكين المدن المصرية من تحقيق رؤية 2030}, journal = {JES.

Achieving such goals requires more efficient and responsive urban management tools. Accustomed tools are ineffective to enabling cities to achieve such goals. Since 1990, global awareness has been directed towards using ICT in urban management. Creating a smart self-organizing system to manage and monitor cities' performance can accelerate improving economic competitiveness, sustainability, and quality of life. Egypt has an ambitious strategy: Egypt's 2030 vision for achieving sustainability and improving the quality of life. while current urban management systems cannot accomplish such tasks. Therefore, this paper aimed to develop a conceptual model for a GIS-based urban management tool that enabling Egyptian cities to achieve Egypt's vision 2030. To achieve this goal the researcher relied on: 1) Recognizing the city's self-organizing system and identifying the role of geographic information systems in managing the urban transformation process and monitoring the city's performance; 2) Evaluating the capability of key performance indicators that were developed to measure the achievement of Egypt's 2030 vision. To achieve the first goal, a systematic literature review was conducted; while to achieve the second goal, KPIs of Egypt's 2030 vision were assessed with using strategic objectives/KPIs matrix as well as using comparative analysis with international evaluating systems. The contribution of this paper is twofold: 1 -  Theoretical contribution that built the bridge between the theory of self-organizing system and the management of cities; 2- Practical contribution represented by: a) the conceptual model, which helps in understanding the components of the smart system for monitoring and evaluating the performance of cities, and the relationship between them; and b) The evolved list of KPIs that track the city's performance  in the six domains of city (economy, environment, mobility, living, community, and governance), to ensure achieving desired goals of Egypt's 2030 vision. نتيجة للقلق العالمي المتزايد بشأن قضايا الاستدامة وتغير المناخ؛ تعهدت الدول بإيجاد وسائل للحفاظ على الموارد واحداث توازن بين مجالات التنمية. وذلك يتطلب إدارة حضرية أكثر كفاءة وأسرع استجابةً فأدوات الإدارة الحضرية التقليدية قاصرة ولا تستطيع تمكين المدن من تحقيق تلك الأهداف بالكفاءة المطلوبة. ومنذ 1990 توجه الاهتمام العالمي نحو التقنيات وتكنولوجيا المعلومات لاستخدامها كعامل محفز للتنافسية الاقتصادية والاستدامة وجودة الحياة.؛ وذلك من خلال تكوين نظام ذكي ذاتي التنظيم لإدارة ومراقبة أداء المدينة. وعلى الرغم من قيام الدولة المصرية بإعداد استراتيجية طموحة: رؤية مصر 2030 لتحقيق الاستدامة وتحسين جودة الحياة. إلا أن نظم إدارة ومراقبة المدن الحالية لا تستطيع انجاز تلك المهمة. لذلك يهدف البحث إلى تطوير نموذج تصوري لأداة مبنية على نظم المعلومات الجغرافية لتقويم أداء المدن وتمكينها وتتبع تقدمها نحو أهداف التنمية المستدامة -لتحقيق رؤية مصر 2030. لتحقيق هذا الهدف يعتمد البحث على: 1) فهم نظام الادارة الذاتية للمدينة والتعرف على دور نظم المعلومات الجغرافية في إدارة عملية التحول الحضري ومراقبة اداء المدينة؛ 2) تقييم مدى كفاية مؤشرات قياس الأداء التي تم وضعها لرصد تحقيق أهداف استراتيجية التنمية المستدامة: مصر 2030. ولتحقيق الهدف الأول تم استخدام منهجية المراجعة المنهجية للأدبيات والأبحاث العلمية المحكمة، بينما تم مراجعة الأهداف مع المؤشرات والمقارنة المرجعية لتحقيق الهدف الثاني. وتتمثل المساهمة العلمية لهذه الورقة في شقين: 1- الشق النظري والذي يعد جسر للربط بين نظرية التنظيم الذاتي ونظام إدارة وتقويم المدينة؛ 2- الشق العملي والمتمثل في النموذج التصوري والذي يساعد في فهم مكونات النظام الذكي لمراقبة وتقويم أداء المدن، والعلاقة بينها؛ كما تم رفع مستوى كفاية مؤشرات قياس الأثر لتتبع مؤشرات أداء المدينة في المجالات الست (الاقتصاد والبيئة والتنقل والمعيشة والمجتمع وادارة المدينة) مما يضمن تحقيق الأهداف المنشودة.}, keywords = {Smart urban management systems,Urban monitoring- Urban indicators - GIS - Egyptian cities}, url = {https://jesaun.journals.ekb.eg/article_303133.html}, eprint = {https://jesaun.journals.ekb.eg/article_303133_62f292c0710f03ec1a3dcc760703415b.pdf} } @article { author = {عجلان, علي بن and العيسان الغامدي, محمد}, title = {The Role of Field Training in Improving Professional Practice Among Students of the College of Architecture and Planning, King Saud University دور التدريب الميداني في تحسين الممارسة المهنية لدى طلاب كلية العمارة والتخطيط بجامعة الملك سعود}, journal = {JES.

Is it also true from the point of views of students of the Architecture and Planning Faculty at King Saud University in Riyadh? This is the main question that this study seeks to answer. King Saud University was chosen because of the history of the College of Architecture and Planning as the oldest school at GCC and Arabian Peninsula. The College is also keen to provide summer training programs for students in many government bodies, offices, and local and foreign companies. In order to achieve the objective of the study, a questionnaire was distributed to 85 students who were trained between 2015 and 2016. The first question was about students’ evaluation for the training supervisor and the second question related to students’ evaluation for the training institute and the third question related to students’ evaluation for the content of the training program. The questionnaire aimed to identify the most important problems facing field training and its role in improving the professional practice of the students at the College of Architecture and Planning at KSU. The questionnaire also aimed to investigate the students’ views about the field training program offered to them in terms of training content and Its compatibility with the theoretical study. The results of the questionnaire analysis showed students' overall satisfaction with the field training they received, which was generally intended to relate the practical part to theoretical. The research indicated that training may not achieve the desired goal due to some problems. One of the most important problems affecting the achievement of the objectives of the field training is the lack of a clear plan for training, or the existence of an organized plan but not being committed by the implementing agencies. Failure to adhere to the timetable for training is one of the major problems that hinder the achievement of the objectives of field training. The study recommended that students must complete the training period to achieve the benefit. It recommended that the supervisor of the training should follow up trainees in continuous method and with strong cooperation with the provider of the training. التدريب الميداني حلقة وصل بين التعليم المعماري والممارسة المهنية، إذ أنه يمثل الخبرة العملية الأولى لطالب العمارة في التعايش مع بيئة مهنية واقعية يتلمس من خلالها تطبيق علوم ومعارف تلقاها على مقاعد الدراسة. تهدف هذه الدراسة إلى استطلاع وجهة نظر طلبة كلية العمارة والتخطيط في جامعة الملك سعود بالرياض عن دور برنامج التدريب الميداني الذي تلقوه في تحسين الممارسة المهنية لديهم،  وقد وقع الاختيار على جامعة الملك سعود بوصف كلية العمارة والتخطيط بها من أقدم كليات العمارة بمنطقة الخليج العربي وشبه الجزيرة وتوفر لطلابها مقاعد تدريبية في الكثير من الهيئات الحكومية والمكاتب والشركات المحلية والأجنبية.   ومن أجل تحقيق هدف الدراسة، تم توزيع استبانة على جميع الطلاب الذين تلقوا تدريبهم ما بين عامي (2015 و2016) وتم استجابة(85) 85 طالبا يمثلون (42.5%) من مجتمع الدراسة وكانت الاستبانة موزعة على ثلاثة محاور؛ المحور الأول يستقصي وجهة نظر الطالب بمشرف التدريب من قبل الكلية والثاني يستقصي وجهة نظر الطالب بالجهة التي يتدرب بها والمحتوى التدريبي الذي تلقاه والثالث يتعلق بالدور الذي يقوم به الطالب لإنهاء متطلبات التدريب. تهدف الاستبانة إلى تحديد أهم المشكلات التي تواجه التدريب الميداني وتحديد دوره في تحسين الممارسة المهنية لدى طلاب كلية العمارة والتخطيط بجامعة الملك سعود، ومعرفة آرائهم حول برنامج التدريب الميداني المقدم لهم من حيث المحتوى التدريبي ومدى توافقه مع الدراسة النظرية. أظهرت نتائج تحليل الاستبانة رضا الطلاب بشكل عام عن التدريب الميداني الذي تلقوه، لكنها أظهرت وجود بعض المشاكل التي تؤثر على تحقيق أهداف التدريب الميداني ومنها عدم وجود خطة واضحة للتدريب، أو وجود خطة منظمة ولكن لا يتم الالتزام بها من قبل الجهات المنفذة. كما أن عدم الالتزام بالجدول الزمنى المخصص للتدريب يعد من المشاكل التي تعوق تحقيق الأهداف المرجوة من التدريب الميداني. أوصت الدراسة بالاهتمام بمرحلة ما قبل التدريب والمراجعة الدورية لمحتوى التدريب الميداني والتنسيق المستمر مع الجهة المدربة مع ربط التدريب بمتطلبات واستراتيجيات رؤية (2030) وضرورة تقديم شرح واضح للطلاب عن برنامج التدريب وماهيته ومساعدتهم على فهم محتوى البرنامج والمتوقع منهم من قبل الجهة المدربة. كما أوصت الدراسة بضرورة متابعة الطلبة المتدربين بصورة مكثفة أثناء فترة التدريب والوقوف على ما قد يعترضهم من اشكاليات ووضع الحلول لها أولا بأول. وأوصت الدراسة – أخيرا- بالاهتمام بمرحلة ما بعد التدريب وذلك بالتقويم المستمر لبرنامج التدريب وحصر الايجابيات وتلافي السلبيات.}, keywords = {Field Training, College of Architecture and Planning, King Saud University, Architectural Education, Architecture and Planning Field. التدريب الميداني,طلاب كلية العمارة والتخطيط,جامعة الملك سعود,التعليم المعماري,مجال العمارة والتخطيط}, url = {https://jesaun.journals.ekb.eg/article_338738.html}, eprint = {https://jesaun.journals.ekb.eg/article_338738_cfe7d416d900b204f3497f89c39435ae.pdf} }
