The article is final after making all the modifications. 2,259 / 5,000 يهدف البحث إلى قياس وتحليل الفجوة بين الواقع الفعلي لبنود التخطيط والدعم وفق المواصفة (IATF16949:2016) في مصنع البطاريات أحد مصانع الشركة العامة لصناعة وتجهيز السيارات، وكذلك التعرف على نقاط القوة والضعف لبنود التخطيط والدعم وفق المواصفة محل البحث. ينطلق البحث من حاجة الشركة العامة لصناعة وتجهيز السيارات إلى إتباع المعايير العالمية في صناعة السيارات والمنتجات المرتبطة بها، إذ تم اختيار معمل بطاريات السيارات في بغداد الوزيرية أحد مصانع الشركة المبحوثة كعينة للبحث، ونظراً لكثرة متطلبات المواصفة المبحوثة فقد تم إدخال فقرات التخطيط والدعم في نظام إدارة جودتها، إذ تم إستخدام قائمة المراجعة والتي تضمنت ثمانية محاور (إجراءات معالجة المخاطر، أهداف الجودة والتخطيط لتحقيقها، تخطيط التغيير، الموارد، الكفاءة، التوعية، الإتصال، والمعلومات الموثقة)، والتي تندرج ضمن متطلبات فقرات التخطيط والدعم وفقاً للمواصفة المبحوثة، وتم إعتماد مجموعة من الأساليب الإحصائية منها (المتوسط الحسابي المرجح، القياس النسبي، قياس حجم الفجوة). توصل البحث إلى وجود فجوة بين الواقع الفعلي للمصنع المبحوث وبنود التخطيط والدعم وفق المواصفة IATF16949:2016، حيث بلغت الفجوة الكلية (74%) لبند التخطيط، و(55%) لبند الدعم، وتعود هذه الفجوة إلى أسباب عديدة، تم تشخيصها في نقاط ضعف، حيث بلغت نسبة التنفيذ والتوثيق (26%) لبند التخطيط، و(45%) لبند الدعم، وتعود تلك النسبة إلى نقاط القوة التي تم تشخيصها لكل من بنود التخطيط والدعم، وتمت مراجعة قوائم المراجعة وفقاً لمتطلبات بنود التخطيط والدعم وذلك للوقوف على الواقع الفعلي في المصنع المبحوث، وتعزيز جوانبه الإيجابية التي حققت أعلى معدلات التطبيق والتوثيق، والسعي إلى إزالة الجوانب السلبية التي حققت أدنى معدلات التطبيق والتوثيق.
The acceptance sampling plans for generalized exponential distribution, when life time experiment is truncated at a pre-determined time are provided in this article. The two parameters (α, λ), (Scale parameters and Shape parameters) are estimated by LSE, WLSE and the Best Estimator’s for various samples sizes are used to find the ratio of true mean time to a pre-determined, and are used to find the smallest possible sample size required to ensure the producer’s risks, with a pre-fixed probability (1 - P*). The result of estimations and of sampling plans is provided in tables.
Key words: Generalized Exponential Distribution, Acceptance Sampling Plan, and Consumer’s and Producer Risks

Pro inflammatory cytokines are critical parts of the pathophysiological processes to which treatment can be applied. The aim of this study was to evaluate 8-OHdG and pro inflammatory cytokines concentration in colon carcinoma patients. Blood samples were taken before treatment from 50 incident cases with colon cancer (stage III) admitted for health examination at the Nanakali Hospital in Erbil city with 45 healthy samples of controls with age range between 38-69 years for both groups. All studied parameters were estimated by ELISA. Participants at this study were 95 Participants ranged in age from 38 to 69 years, 50 Participants had been newly diagnosed wi

Show MoreThe constructivist learning model is one of the models of constructivist theory in learning, as it generally emphasizes the active role of the learner during learning, in addition to that the intellectual and actual participation in the various activities to help students gain the skills of analyzing artistic works. The current research aims to know the effectiveness of the constructivist learning model in the acquisition of the skills of the Institute of Fine Arts for the skills of (technical work analysis). To achieve the goal, the researcher formulated the following hypothesis: There are no statistically significant differences between the average scores of the experimental group students in the skill test for analyzing artworks befor

Show MoreArts acts to reduce and exclude everything that is not necessary in the delivery of meaning, especially representative performance, which is based on the intensification of the physical and vocal actions, and in drawing the dimensions of the character. And because that, the artistic staff, among others in the ministry of education, are considered the cornerstone, in the development of theatrical activities in schools, this research came to find out the extent to which teachers in primary schools, in secondary schools and artistic supervisors rely on shorthand mechanisms in the representative performance.
The current research relied on the descriptive approach, in analyzing his sample, which was deliberately chosen, Among the most imp
The research seeks to identify the effectiveness of a selective program in modifying irrational thinking that causes anger among an important class of societies in general. namely teachers. Specifically female teachers because of the pressures they suffer because of the nature of this profession. It may develop into anger outburst, which may cause irrational thinking arose as a result of the different situations they are going through. The sample of the program consisted of (12) teachers in Egypt, from different educational sectors. The researcher intended to clarify the emotion of anger and the irrational thoughts associated with it and the contribution of the selective counseling program in modifying those irrational thinking.

... Show MoreResearchers have increased interest in recent years in determining the optimum sample size to obtain sufficient accuracy and estimation and to obtain high-precision parameters in order to evaluate a large number of tests in the field of diagnosis at the same time. In this research, two methods were used to determine the optimum sample size to estimate the parameters of high-dimensional data. These methods are the Bennett inequality method and the regression method. The nonlinear logistic regression model is estimated by the size of each sampling method in high-dimensional data using artificial intelligence, which is the method of artificial neural network (ANN) as it gives a high-precision estimate commensurate with the dat
