Cost indices are considered as important tools which help both the owner and the contractor to identify the primary evaluation of project depending on the cost of previous and similar project in easy and quick form, and the most important using ways by researchers in process modernization previous cost in shortest time and least effort. Methodology was adopted to help in designing cost index taking into account weights of chosen groups instead of weights of items, so It has been suggested three cost indices for school building in Lattakia by studying a sample consists of 32 schools were constructed between 2001-2012, and then The best cost index between them which explains the biggest portion of square meter cost variations due to escalation was selected, also it has been suggested a model that reflect the relationship between cost of square meter and developed cost index for corresponding year through statically program spss.

Research summary
تعتبر مؤشرات الكلفة أدوات هامة تساعد المالك والمقاول في تحديد القيمة التقديرية الأولية للمشاريع بناءً على كلفة مشاريع مماثلة سابقة. يهدف البحث إلى اقتراح مؤشرات كلفة خاصة بمشاريع الأبنية المدرسية في محافظة اللاذقية، وذلك من خلال دراسة عينة من 32 مدرسة شيدت بين عامي 2001 و2012. اعتمدت المنهجية على تصميم مؤشرات تأخذ بعين الاعتبار أوزان مجموعات مختارة بدلاً من أوزان البنود الفردية. تم اقتراح ثلاثة مؤشرات للكلفة، واختيار الأفضل بينها بناءً على تفسيره لأكبر نسبة من التغيرات في كلفة المتر المربع الناتجة عن التضخم. كما تم تطوير نموذج يربط بين كلفة المتر المربع ومؤشر الكلفة المصمم باستخدام البرنامج الإحصائي SPSS. خلص البحث إلى أن مؤشر الكلفة الثالث هو الأفضل، حيث يفسر 83.9% من التغيرات في كلفة المتر المربع. أوصى البحث بتطبيق المنهجية على أنواع أخرى من المشاريع الهندسية وتوثيق جميع المشاريع لإنشاء قاعدة بيانات يمكن الاستفادة منها في المستقبل.
Critical review
تعتبر الدراسة خطوة هامة نحو تحسين دقة تقديرات الكلفة لمشاريع الأبنية المدرسية في محافظة اللاذقية. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، قد يكون حجم العينة المكون من 32 مدرسة غير كافٍ لتعميم النتائج على نطاق أوسع. ثانياً، لم تأخذ الدراسة في الاعتبار بعض العوامل الأخرى التي قد تؤثر على كلفة المشاريع مثل التغيرات في أسعار المواد الخام والعوامل البيئية. ثالثاً، قد يكون من المفيد تضمين تحليل حساسية لتقييم مدى تأثير التغيرات في الأوزان المستخدمة في المؤشرات على النتائج النهائية. وأخيراً، يمكن تحسين الدراسة من خلال مقارنة المؤشرات المقترحة مع مؤشرات كلفة مستخدمة في دول أخرى لتقييم مدى دقتها وفعاليتها.

This study aimed to assessing the role of school administration in health education in basic education schools in Lattakia city. The researcher used analytical descriptive method. The questionnaire was used to collect the study data from 30 principal s, who were chosen by using simple random sample. The findings indicated that the degree of the role of the school administration in health education in basic education schools of Lattakia city was low average as a whole is (2.42). The degree in achieving the means of health and safety was low average is (2.58), securing good environment suitable for good nutrition was low average is (2.25), and health culture was the lowest average is (2.10). Where achieving hygiene was the highest average is (2.78). This study recommended exploiting and following the applying of the health education programs. Developing the health culture programs of the school pupils and activating the role of health guide in school health field by holding seminars, training courses and sessions.
As a result of research, one can conclude that there are many differences between the attitudes of teachers in the suburb and the city towards school management. The relationship between school managers and teachers in the suburb is so friendly and w armly than the relationship between them in the city. This will definitely affect the attitudes of teachers toward the school administration. There are also many differences between the attitudes of male and female teachers and towards the school administration, because women always tend to do their best, but sometimes her thoughts don't accord with the school manger's thoughts. This will in turn create a gap between their thoughts and points of view. As a result, female teachers' attitude toward the school administration will be affected. As we know the school administration has a significant impact on activating the role of teachers, as it will always stand behind any failure or success.It represents the educational goals and policy and has the responsibility of translating them to real work. School mangers with strong personality have the power to positively affecttheir teachers. They also play a seminal rolein achieving the main goals of their schools. So, the success of the school depends on the way it is managed, and the general system of any school is related with the quality of the manger and the way the school is being managed.
Many studies have tried to determine the impact of change orders on the cost and time of the project, which in turn leads to differences and disputes between contractors and owners. Where change orders dealt with in various engineering projects. T his search displays formal causes of change orders occurring during the life cycle of the project in Syrian coastal zone. Particular building projects are studied, and the most important impact on completion of the project indicators (cost_time) is discussed. Also identifies the party responsible for the change, and shows the weak points during follow the change order life cycle and provides recommendations for each of the responsible parties, stressing the need to monitor performance in order to manage change order and address the causes and impact alleviation. The prediction models were drafted at additional cost that may result from change orders.
In this paper, we study the non stationary index ρ of sequences in Hilbert space H. Applying the correlation differences matrix of evolutionary representable sequences we achieved to the necessary and sufficient condition which’s for the non stat ionary index is bounded. And according to the Quasi-Hankel sequences definition we join between these sequences and evolutionary once.
This researchdeals with the topic of controlling the cost of concrete bridge projects in the early design phase. The research aims at using cost controlling as an auxiliary tool for designing and decision making.Cost control methodology has been pr oposed based on modeling the elements of structure, and proposing a method forcost estimate. This method based on estimating of quantitiesfrom the general parameters of the structure and prices are being updated periodically.The proposed methodology studiesmany available alternatives that werechosen by the designer andevaluate thesealternativeseconomically.
