سعى البحث الحالي الى التعرف على بعض الاضطرابات السلوكية والانفعالية وعلاقتها بالاستعمال المفرط للالعاب الالكترونية لدى تلاميذ المرحلة الابتدائية, إذ يواجه التلاميذ مشكلات سلوكية عديدة ،تظهر من خلال تعاملهم مع اقرانهم في البيت او في المدرسة والتي قد تتطور عند بعضهم وتتحول الى اضطرابات نفسية،مما يؤدي بهم الى ضعف التعلم وسوء التوافق في حياتهم المدرسية ويصبحون عُرضة للا صابة بالامراض النفسية ،إذا لم يتم تشخيصها بوقت مبكر وتوضع الحلول لمعالجتها أو الحد من آثاره وقد ترتبط هذه الاضطرابات بمتغيرات تؤثر في شخصية التلميذ قد تكون منها الافراط في استخدام الالعاب الالكترونية والتي صار الاطفال ينافسون الكبار في إقتنائها وشرائها ،إذ باتت تُشكل ولعاً وشيئاً أساسياً لايمكن الاستغناء عنه حيث هدفت الدراسة الى: 1-التعرف على مستوى الاضطرابات السلوكية والانفعالية (العدوان، الغضب ،العناد ) لدى التلاميذ . 2-التعرف على الفروق في مستوى الاضطرابات السلوكية والانفعالية (العدوان، الغضب ،العناد ) للتلاميذ (ذكور اناث) 3-التعرف على مستوى الاستعمال المفرط للالعاب الالكترونية لتلاميذ المرحلة الابتدائية. 4-التعرف على الفروق في مستوى الاستعمال المفرط على الالعاب الالكترونية للتلاميذ(ذكور اناث ) 5 –العلاقة الارتباطية بين بعض الاضطرابات السلوكية والانفعالية والاستعمال المفرط للالعاب الالكترونية لدى تلاميذ المرحلة الابتدائية) استخدمت فيها الباحثة منهج البحث الوصفي على عينة تتالف من (150) تلميذ وتلميذة ,اختيرت بالطريقة العشوائية,وبواقع (80) تلميذ و(70) تلميذة,للصفين الخامس والسادس الابتدائي ،حيث اظهرت نتائج البحث الى ان افراد عينة البحث لديهم مستوى عال من العدوان والغضب و مستوى منخفض من العناد وإن لديهم استعمالاً مفرطاً للالعاب الالكترونية، ولايوجد فروقا ذات دلالة احصائية بين الذكور والاناث في درجات مقياس الاضطرابات السلوكية والانفعالية (العدوان ،الغضب ،العناد) كما لايوجد فروقا ذات دلالة احصائية بين الذكور والاناث في الاستعمال المفرط للالعاب الالكترونية,وان هناك علاقة طردية موجبة ذات دلالة احصائية بين كل من (اضطراب العدوان والاستعمال المفرط للالعاب الالكترونية) و(الغضب والاستعمال المفرط للالعاب الالكترونية ), أي كلما زاد الافراط في استخدام الالعاب الالكترونية زاد اضطراب العدوان والغضب لدى التلاميذ ولاتوجد علاقة بين اضطراب العناد والاستعمال المفرط للالعاب الالكترونية لدى عينة البحث. استخدمت فيها الباحثة الاختبار التائي (T-test (لعينتين مستقلتين ,ومعاملات الارتباط بيرسون للتعرف على طبيعة العلاقة بين المتغيرين.ثم اوصت الباحثة على الحرص على توعية التلاميذ بمخاطر ممارسة الالعاب وبشكل مستمر وتأثيره على صحتهم النفسية والعقلية وتشجيع رغبات وميول التلاميذ وتنمية روح العمل لديهم بما يحتاج الى جهد جسمي أكثر مما يحتاج الى جهد عقلي عند التلاميذ ذوي النشاط الجسمي الزائد عن المعتاد .
Because of the experience of the mixture problem of high correlation and the existence of linear MultiCollinearity between the explanatory variables, because of the constraint of the unit and the interactions between them in the model, which increases the existence of links between the explanatory variables and this is illustrated by the variance inflation vector (VIF), L-Pseudo component to reduce the bond between the components of the mixture.
To estimate the parameters of the mixture model, we used in our research the use of methods that increase bias and reduce variance, such as the Ridge Regression Method and the Least Absolute Shrinkage and Selection Operator (LASSO) method a
... Show MoreThis paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting a real-valued vector derived from the golden section. Random and so-called “spread” interleavers are also considered. Turbo-code performance results are presented and compared for the various interleaving strategies. Of the interleavers considered, the dithered golden interleaver typically provides the best performance, especially for low code rates and large block sizes. The golden relative prime interleaver is shown to work surprisingly well for high puncture rates. These interleav

with a total of 100 male and female pupils and two ages(8-9 and 10-11 years),
were selected randomly to study the relationship between the breakfast meal and
the academic level, the socioeconomic situation, and the number of family
members. The study showed a positive linear correlation between the morning
meal, and academic level of students for both two covered ages, also showed a
clear impact between the development of family's socioeconomic situation and
their nutrition level. There were an increase in the percentage of pupils aged 8-9
years with a poor nutrition when they were belonged to a poor or medium
socioeconomic families,
The study aimed to determine of some Optimum conditions for bioremediation and removing of seven mineral elements included hexavalent chromium, nickel, cobalt, cadmium, lead, iron and copper as either alone or in group by living and heat treated cells of baker’s yeast Saccharomyces cerevisiae. The dried baker's yeast from Aldnaamaya China Company was used in this study. Biochemical tests was used to ensure yeast belonging to S. cerevisiae and then used to remove the mentioned mineral elementes under different conditions which included incubation period, pH, and temperature. It was found that the best of these conditions was 60 minutes for duration of incubation, 6 for pH, 25 ᵒC for temperature. During the study the behavior of living

Abstract
Due to the momentum of winning in the streets of the city of Baghdad as a result of the large number of checkpoints so felt researcher to conduct a field visit to find out the main reasons that led to this congestion and to find practical solutions to mitigate wastage winning the arrival time citizen to where you want the least possible time.
This research aims to overcome the difficulties experienced by citizens to reach their places of work and reduce waste at the time of service and waiting time as well as reduce the cost of waiting.

We conclude that this study has dealt with an important aspect of the book that was not clearly defined in the book as it was derived through the book's translations, namely, the extraction of those urban structures of the city of Baghdad, which were of great importance in the religious, cultural, economic and social life at that time, The important link that reflected the development of the Islamic city in general and Baghdad in particular, as he addressed such urban facilities through the translations of the book that did not offer the outline or information about those facilities, but only the name only, and here lies the difficulty in addressing Such as T.
