يهدف البحث الحالي التعرف على: - 1- تحديات الأم في تحقيق الأمن الرقمي لطفل المرحلة الابتدائية في ظل الثورة المعلوماتية 2- وجود فروق ذات دلالة إحصائية على مقياس الأمن الرقمي وفق متغير التحصيل الدراسي للأم (ابتدائي- متوسطة-إعدادية-بكالوريوس فما فوق)؟ 3- وجود فروق ذات دلالة إحصائية على مقياس الأمن الرقمي وفق متغير العمر للأم (٢٦-٣٠، ٣١-٣٥، ٣٦-٤٠، ٤١-٤٥)؟ اشتملت عينة البحث على (٦٣٣) من أمهات أطفال المرحلة الابتدائية بمحافظة بغداد تم اختيارهم بالطريقة العشوائية الطبقية من مدارس المديريات الستة، وقامت الباحثات ببناء مقياس يتكون من (۳۰) فقرة موزعة بالتساوي على المجالات الثلاث، المجال الأول (تحديات الأم في حماية الطفل من مخاطر المحتوى الرقمي المعروض)، المجال الثاني تحديات الأم في حماية الطفل من مخاطر الاتصال بالإنترنت)، والمجال الثالث تحديات الأم في حماية الطفل من مخاطر السلوك السيء)، وتم استخراج الخصائص السايكومترية للاستبانة (التميز، الصدق، الثبات)، وأظهرت النتائج أن الأم تواجه التحديات في حماية الطفل بدرجة فوق المتوسط، وأن مخاطر الاتصال بالإنترنت كان الأكثر تحديا، ثم مخاطر المحتوى الرقمي المعروض، ثم مخاطر السلوك السيئ، و لا توجد فروق ذات دلالة إحصائية وفق متغير التحصيل الدراسي للأم، و متغير العمر للأم.

... Show MoreMany studies of the relationship between COVID-19 and different factors have been conducted since the beginning of the corona pandemic. The relationship between COVID-19 and different biomarkers including ABO blood groups, D-dimer, Ferritin and CRP, was examined. Six hundred (600) patients, were included in this trial among them, 324 (56%) females and the rest 276 (46%) were males. The frequencies of blood types A, B, AB, and O were 25.33, 38.00, 31.33, and 5.33%, respectively, in the case group. Association analysis between the ABO blood group and D-dimer, Ferritin and CRP of COVID-19 patients indicated that there was a statistically significant difference for Ferritin (P≤0.01), but no-significant differences for both D-dimer and CRP.

... Show MoreIn this paper, we present a comparison of double informative priors which are assumed for the parameter of inverted exponential distribution.To estimate the parameter of inverted exponential distribution by using Bayes estimation ,will be used two different kind of information in the Bayes estimation; two different priors have been selected for the parameter of inverted exponential distribution. Also assumed Chi-squared - Gamma distribution, Chi-squared - Erlang distribution, and- Gamma- Erlang distribution as double priors. The results are the derivations of these estimators under the squared error loss function with three different double priors.
