Research summary
تناولت هذه الدراسة الإحصائية والتحليلية تقدير الجرعات الإشعاعية الناتجة عن استخدام بعض أجهزة التصوير الطبية في مراكز طبية بمنطقتي حمص وحماة. هدفت الدراسة إلى قياس الجرعات الناتجة عن التصوير الطبقي المحوري، الصور الشعاعية البسيطة، والصور الماموغرافية. أظهرت النتائج أن الجرعات الناتجة عن التصوير الشعاعي البسيط تتراوح بين 0.47µSv للقدم و14.42µSv للصدر، وهي ضمن الحدود المسموح بها من قبل هيئة الطاقة الذرية السورية. بالنسبة للصور الماموغرافية، تراوحت الجرعات بين 1.67µSv و20µSv، وهي تعتبر منخفضة إلى متوسطة. أما التصوير الطبقي المحوري، فقد أظهرت القياسات أن الجرعات تتراوح بين 26.22µSv للحوض و65.23µSv للرأس، وهي مرتفعة مقارنة بالأجهزة الأخرى وأحيانًا تتجاوز القيم الموصى بها. كما أظهرت القياسات أن جرعة الخلفية الطبيعية تتراوح بين 0.030µSv و0.055µSv. أوصت الدراسة بضرورة اتباع الإجراءات الوقائية وتسجيل الجرعات الإشعاعية التي يتلقاها المرضى في سجلات طبية خاصة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تقييم الجرعات الإشعاعية الناتجة عن استخدام الأجهزة الطبية المختلفة، إلا أنها تفتقر إلى تحليل أعمق للعوامل المؤثرة على تباين الجرعات بين المراكز المختلفة مثل قدم الأجهزة وخبرة الفنيين. كما أن الدراسة لم تتناول تأثير الجرعات الإشعاعية على المدى الطويل بشكل كافٍ، ولم تقدم توصيات واضحة حول كيفية تحسين تقنيات التصوير لتقليل الجرعات. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت مقارنة مع معايير دولية أخرى للجرعات الإشعاعية.

This research handles the economic effects of taxes and fees presented as a statistical and analytical study during the period 1990-2009 in Syria. It was based on the annual statistical data issued by the Central Bureau of Statistics. Using the sta tistic programme (SPSS) we have made econometric models to estimate the parameters of models of the impact of the tax on all public investment, private investment, gross capital formation, consumption, and these models can be used in the prediction of these variables, We have reached many important results, among which, the clear centrifugal relationship between taxes and total fixed capital formation in both public and private sectors. In fact, the tax itself had not been an effective tool in increasing the rate of growth of both public and private investment. It also shows us that the Syrian tax system depends on indirect taxes (consumption tax) that reduce the consumption of individuals contributing to the decline in the volume of employment and national income, In addition to the significant decline in distributing the national income fairly due to high indirect taxes which consequently affected the low-income category, Show us through the curve of Lawrence.
Fetus images produced by 2D ultrasound devices are ambiguous and lack precision. This led to the need for offering a 3D visualization of the fetus, which allows visualizing width, height, and angle, in order to get additional information about the fetus, and detect fetus abnormalities. We explain in this paper our method in producing 3D models of the fetus from 2D images using a computer system without the need for changing the 2D imaging devices, and without using position sensors. Our method is based on passing the probe over the pregnant woman's abdomen and make a manual scan for the entire body of the fetus from top of the head till the bottom of his feet, then it saves this scan as a video clip then send, it to the computer which segments the video into multiple images which are saved and later processed using digital processing principles of images. Then these processed images are reconstructed to produce the volume matrix and then display it in a 3D form using 3D model construction methods. We applied our software on various fetuses of different ages and got volume images which are considered good in comparison with the images offered by currently available systems and devices. The precision of the images we got, differs according to the change in fetus pose, amniotic liquid, and fetus size, The obstetrician or gynecologist can retrieve more precise details by changing the angle and displaying volume images of certain part of the fetus body.
The research aims to detecting the factors that play an effective role in determining the level of insurance awareness in a specimen of household heads in Lattakia city, It included (438) household head using factorial analysis method to analyze ques tionnaire data made to measure the level of the insurance awareness at the specimen individuals. This measurement included many indexes to measure both of the cognitive and the elective dimensions of insurance awareness. the cognitive dimension includes three variables (fear of danger, apprehension of the need for insurance, and acquaintance of available insurance types). The elective dimension includes two main variables (the intention of carrying out insurance, and having a specific attitude towards insurance). The research showed that there is two main factors determining the level of the insurance awareness at the individuals of the studied specimen. The first factor is related to the social factors that surrounds the individual, while the second one is related to personal factors.
Information and communication technology (ICT), Gross capital formation, Openness, and Inflation are frequently well-thought-out as important drivers of economic growth for all countries, and especially for developing countries. This study aims to examine the effect of these factors no economic growth in Syria covering the period from 1995-2012, with main interest of the impact of ICT. To this end, the study utilized annual time series data set over the period 1990 to 2010. Econometric techniques include testing the stationary of data by applying (ADF) test and applying Autoregressive Distributed Lag (ARDL) method of estimation. Moreover, Short run and long run estimates were found . The paper confirms a negative and statistically significant relationship between the economic growth and technology index in the short run, but the relationship becomes positive and statistically significant in the long run. This paper confirms a negative and statistically significant relationship between the economic growth and GFC in the short run, but the relationship becomes positive and statistically significant in the long run, where the relationship between openness and economic growth is positive both in the short and long run, whereas the relationship between the inflation rate and economic growth is negative both in the short and long run.
