This research has been implemented in Homs city-Syria, in order to study the configuration of the road network in residential district, and the debates about the most efficient pattern in terms of functional performance, treeor grid pattern, or other patterns. In order to do that, it focused on the planning principles of functional performance, which can be summarized to:( proximity, permeability, security). And worked on identifying Accurately the functional performance indicators, and there measuring method, and they were (Cell / Cul ratio – T / X ratio- distant between the center and the periphery - number of cells per unit area –hierarchy). And applied it on the case studies: (organized / newly planned residential districts). It turns out that the road network should have a medium proximity and permeability for traffic,while it should be high for pedestrian. Therefore,the network patternCandidate forbetterfunctional performance when it's nearly in the mid-way between (tree and grid).

Research summary
أجري هذا البحث على مدينة حمص في سوريا كحالة دراسية بهدف تقييم الأداء الوظيفي لشبكة الطرق في الأحياء السكنية بناءً على بنيتها. تركز البحث على مقارنة الأنماط الشبكية (grid) والشجرية (tree) من حيث الكفاءة الوظيفية، مع التركيز على مبادئ التقاربية، النفاذية، والأمان. تم تحديد مؤشرات الأداء الوظيفي مثل نسبة عدد الخلايا إلى النهايات المغلقة (Cell / Cul ratio)، نسبة التقاطعات الثلاثية إلى الرباعية (T / X ratio)، المسافة بين المركز والأطراف، وعدد الخلايا في وحدة المساحة. تم تطبيق هذه المؤشرات على أحياء منظمة وضواحي سكنية حديثة التخطيط في مدينة حمص، حيث تبين أن الشبكات التي تجمع بين سمات النمطين الشبكي والشجري مع مراعاة مبدأ الأمان هي الأكثر كفاءة وظيفياً. خلص البحث إلى أن حي الوعر يتفوق على حي الإنشاءات في مؤشرات الأداء الوظيفي لشبكة الطرق، مما يعزز بيئة صديقة للمشاة ويحقق أداء وظيفي أفضل للحي السكني ككل.
Critical review
دراسة نقدية: يعتبر هذا البحث خطوة مهمة في تقييم الأداء الوظيفي لشبكات الطرق في الأحياء السكنية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين المزيد من الحالات الدراسية من مدن أخرى لتعميم النتائج بشكل أفضل. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية والاجتماعية على الأداء الوظيفي للشبكات الطرقية. ثالثاً، كان من الممكن استخدام تقنيات تحليل بيانات أكثر تقدماً لتحليل المؤشرات بشكل أكثر دقة. وأخيراً، كان من المفيد تقديم توصيات أكثر تفصيلاً حول كيفية تحسين الشبكات الطرقية في الأحياء السكنية القائمة.

The paper proceeds to review the concept of Residential Urban Spaces and their classification, and to limit the variables affecting the performance of the spaces and identify the ways to measure these variables. Then, it conducts a field survey of a variety of spaces in the City of Lattakia. The paper also proceeds to conduct a questionnaire to the urban spaces users and the residents of the surrounding segments of the population in order to identify the users’ opinions and reviews on the current status of the space performance and identify the most important needs and activities favored by the users within the space. It also identifies the reasons behind selecting certain spaces rather than others. After that, the paper proceeds to analyze the data in order to develop a mathematical model that determines the most important variables that affect the performance of the space, positively or negatively. Consequently, a mechanism will be set up to boost the performance of the Residential Urban Spaces by influencing the most powerful variables affecting the spaces and rejecting the weaker ones. Finally, making recommendations to activate the spaces and make it a safe interactive human, socio- cultural environment.
The research aimed to assess the performance of the private banking sector in Syrian Arab Republic during the period between 2010-2018 from a supervisory prospect of the Central Bank to determine the strengths and weaknesses of the banking sector in Syrian Arab Republic. We gathered the statistical data issued by local banks (14 traditional and Islamic banks). The performance of the banks was evaluated separately using the CAMELS model, where the study showed average performance of the operating banks. The researchers deliberately used indicators of capital adequacy, asset quality, management efficiency, profitability, liquidity, and sensitivity to market risks. In addition, the researchers tried to study the effect of stock market risk on the performance of the banking sector by forming a portfolio of shares of banks operating in Syria. The results of the statistical analysis using the SPSS program, through the Discriminant Analysis test, showed the presence of an impact of a number of indicators on the performance of the banking sector. In the end, a model for evaluating the performance of the banking sector was obtained using a multiple regression model and the model is able to explain the performance of the banking sector by 88.4%.
This research work tackles the strange contradiction between the political history and the literary history of the Ottoman period. In the first history, there is a general agreement about its end at the finish of the First World War. In the second , it is commonly held that is end is with the Napolyonic campaign on Egypt in 179g, but some literary historians did not agree; despite this they used the common belief consequently, this work notes that this problem led to two dangerous things: first, the misunderstanding and the underestimation of the Ottoman literature in its important objective and artistic values. After pointing to this problem, the work tries to trace the continued Ottoman elements in the literature of the Renaissance period. It finds out also that this period is so active with the Ottoman reign more than any other period. This in its turn led to the conclusion that the movement of the late Arab literature into modern Arab literature was gradual. Accordingly, this research work considers the First World War as the end of the Arab literature during the Ottoman period.
Housing is an important element of architectural surrounding, that appears to be an outcome of the interaction of a number of factors whether regarding its age, model, location, and area. So any building is valued by its aesthetic historic value as well as its capacity to satisfy the needs and comfort of its inhabitants. The research presents an analytical study of the reality of contemporary housing and its changes in the city of Latakia during the period 1921-2014, to register the most important transformations that have occurred as a result of political, economic and social conditions on the architectural level (housing) and urban level (residential complexes). The research has sum up a set of architectural aspects that have changed in the design of buildings in Latakia , along with the most important reasons causing this change.
The Study focuses on the contemporary planning applications in shaping the urban structure of the residential areas in general and the spatial formation in particular, according to a schematic structure that depends on classification of these space s by kind, function of these special formation and their distinguished characteristics. The study focuses on the gradual scales of the formed spaces within the urban residential structure according to their functions, starting with the external courtyards surrounded by residential buildings whose construction in open space differs from the one in closed space, according to the predominant climatic conditions, then we move to the spaces of motorcar streets and pedestrians roads that have the dynamic and vitality characteristic by the multiplicity of uses, the functions, and the changes of its design structure. Spaces surrounding the public and service buildings form some special distinctive structural points especially when they complement each other with the surrounding buildings in architecture and volume. The formation of aesthetic-visual image in the urban spaces and the visual recognition mechanism divides the urban spaces into three principal types and discusses the relationship between shapes, volumes and colors of the building that form the space and visual sensation with the homogeneity and extension of space. Then the research studies various samples of the urban residential structure of Lattakia city and the spatial formation by performing general classifications of the urban spaces forming this structure according to the type and function of each. Then, we conclude the advantages and disadvantages of the schematic solution and understand the reasons of the negative aspect to be avoided in future.
