هدف البحث إلى بناء مقياسي الرفاهة النفسية وضغوط المنافسة للاعبي جمناستك الأجهزة الشباب، والتعرف على مستوى الرفاهة النفسية لدى لاعبي جمناستك الأجهزة الشباب، والتعرف على مستوى ضغوط المنافسة لدى لاعبي جمناستك الأجهزة الشباب، والتعرف على دور الرفاهة النفسية في خفض ضغوط المنافسة للاعبي جمناستك الأجهزة الشباب، لتكون فرضية البحث بإنه توجد علاقة إرتباط معنوية وإسهام وأثر لنتائج مقياس ضغوط المنافسة بنتائج مقياس ضغوط المنافسة لدى عينة البحث، وأعتمد المنهج الوصفي بإسلوب العلاقات الإرتباطية على عينة من لاعبي جمناستك الأجهزة الشباب للموسوم الرياضي (2023/2024) والموزعين بطبيعتهم على (15) مركزاً للجمباز في بغداد والمحافظات، البالغ عددهم (146) لاعباً، وأختيروا عمدياً جميعهم بإسلوب الحصر الشامل بنسبة (100%)، كما أختير منهم (6) لاعبين عشوائياً للعينة الإستطلاعية بنسبة (4.11 %) من المجتمع الأصل، كما أختير منهم (75) لاعباً عشوائياً لعينة بناء مقياسي البحث بنسبة (51.37 %) من المجتمع الأصل، والمتبقي منهم (65) لاعباً أختيروا لعينة تطبيق البحث الرئيسة بنسبة (44.521 %) من المجتمع الأصل، وبعد الإنتهاء من بناء المقياسين، تم إجراء المسح للمدة الزمنية من يوم (28/2/2024) ولغاية يوم (14/3/2024)، على طالبات لاعبي التطبيق، ومن ثم معالجة النتائج ألياً بنظام الحقيبة الإحصائية SPSS، لتكون الاستنتاجات بإن مقياسي الرفاهة النفسية وضغوط المنافسة بالجمناستك يصلحان لِما تم بنائهما من أجله ويلائمان لاعبي جمناستك الأجهزة الشباب ويتمتعان بالأسس والمعاملات العلمية لقبولهما في علم النفس الرياضي، ويتوافر لدى لاعبي جمناستك الأجهزة الشباب مستوى من الرفاهة النفسية لتمكينهم من خفض ضغوط المنافسة، وتسهم زيادة مستوى الرفاهة النفسية في خفض مستوى ضغوط المنافسة بالجمناستك بعلاقة أرتباط تنحدر خطياً في زيادتها الطردية والأثر الإيجابي، أما التوصيات فكانت بإنه لابد من زيادة أهتمام مدربي الجمناستك بتهيئة البيئة التدريبية الملائمة لرفع مستوى الرفاهة النفسية لدورها وإسهامها وأثرها الإيجابي خفض مستوى ضغوط المنافسة لدى لاعبي جمناستك الأجهزة الشباب، ولابد من الأهتمام بمتابعة قياس كل من الظاهرتين المتضادتان المبحوثتين للاعبي جمناستك الأجهزة الشباب بالقياس النفسي الدوري واعتماد مقياسي البحث الحالي في هذا القياس التتبعي، ومن الضروري عدم المبالغة في فرض مهام تدريبية عالية لاعبي الجمناستك وتقليل الضغط عليهم وعدم إجهادهم، والعمل على دعم ثقتهم بإنفسهم لتجنب ارتفاع ظاهرة ضغوط المنافسة لدى لاعبي جمناستك الأجهزة الشباب. وهذا ما يحقق احد اهداف التنمية المستدامة للامم المتحدة في العراق (التعليم الجيد).
The aim of the research is to measure the change in the impact of the factors of the Corona pandemic on psychological sensitivity and COVID-19 phobia in a sample of Bisha University students and to detect the differences in the phobia (phobia) Covid-19 among the sample members in the measurement before the ban and after the ban was opened, in addition to the differences in psychological sensitivity of The sample has between sizes before and after the spread of the Corona pandemic, as well as the differences in them according to the gender variable (male, female). The researcher relied on the comparative approach. The scale of psychological sensitivity and COVID-19 phobia was applied to a sample of (62) male and female respondents.
... Show MoreThe substantial key to initiate an explicit statistical formula for a physically specified continua is to consider a derivative expression, in order to identify the definitive configuration of the continua itself. Moreover, this statistical formula is to reflect the whole distribution of the formula of which the considered continua is the most likely to be dependent. However, a somewhat mathematically and physically tedious path to arrive at the required statistical formula is needed. The procedure in the present research is to establish, modify, and implement an optimized amalgamation between Airy stress function for elastically-deformed media and the multi-canonical joint probability density functions for multivariate distribution complet
... Show MoreThe local asphalt concrete fracture properties represented by the fracture energy, J-integral, and stress intensity factor are calculated from the results of the three point bending beam test made for pre notches beams specimens with deformation rate of 1.27 mm/min. The results revealed that the stress intensity factor has increased by more than 40% when decreasing the testing temperature 10˚C and increasing the notch depth from 5 to 30mm. The change of asphalt type and content have a limited effect of less than 6%.
A new concrete rheometer is introduced including its innovation, actual design, working rules,
calibration, and reliability. A modified design of Tattersall two-point device is created. Some of
components are purchased from local and foreign markets, while other components and the
manufacturing process are locally fabricated. The matching viscosity method of determining the mixer
viscometer constants is demonstrated and followed to relate torque and rotational speed to yield stress
and viscosity (Bingham parameters). The calibration procedures and its calculation are explained.
Water is used as a Newtonian fluid, while; cement paste (cement + water) with w/c ratio equal to
(0.442) is used as a non-Newtonian fluid. Th
Abstract Introduction: Aphthous stomatitis is a recurring oral ulceration condition that affects a significant proportion of the population. While several factors have been proposed to contribute to its occurrence, the link between caffeine consumption, anxiety levels, and the development of aphthous stomatitis remains unknown. This survey-based study aimed to understand the association between coffee, anxiety, and the development of aphthous stomatitis in this specific demographic, which can provide useful insights for medical management as well as preventive strategies. Material and methods: A structured online questionnaire was distributed via various social media platforms targeting a sample of the Armenian population. The quest
... Show MoreMercuric chloride (HgCl2) pollution and poisoning has been a worldwide health concern for decades, especially after the industrial revolutions. The aim of this study was to investigate the role of resveratrol in reversing the deleterious effects of HgCl2 exposure to resume the normal functions of hepatocyte. To achieve the study, mature Sprague Dawley rats were assigned to five groups. Negative control group (C) kept without any treatment; vehicle-treated group (D) received dimethyl sulfoxide (DMSO); resveratrol-treated group (R), received 100 mg/kg of resveratrol; HgCl2-intoxicated group (HD), received i.p. injection of HgCl2 at a dose of 1 mg/kg for 30 consecutive days along to oral gavage of DMSO; and finally H
... Show MoreThis study aimed to measure digital stress among students at the University of Baghdad and to identify differences in digital stress based on gender (male–female), academic level (first–fourth year), and field of study (scientific–humanities). The study sample consisted of 200 students from the University of Baghdad. The "Digital Stress" scale, developed by the researcher specifically for this study, was applied, and the descriptive-analytical method was adopted. After administering the scale and analyzing the results using appropriate statistical methods, the findings indicated that university students experience a high level of digital stress, while no statistically significant differences were found in digital stress accord

Show MoreThis paper deals with calculate stresses in Knee-Ankle-Foot-Orthosis as a result of the effect vibration during gait cycle for patient wearing KAFO .Experimental part included measurement interface pressure between KAFO and leg due to action muscles and body weigh on Orthosis. also measurement acceleration result from motion of defected leg by accelerometer .Results of Experimental part used input in theoretical part so as to calculate stresses result from applying pressure and acceleration on KAFO by engineering analysis program ANSYS 14.Resultes show stresses values in upper KAFO greater than lower KAFO that is back to muscles more effective in thigh part lead to recoding pressure higher than pressure in shank part.
The study was conducted to investigate the effect of salinity of irrigation water on seeds quality and seedling growth characters for three oat cultivars (Shifaa, Hamel and Pimula) . It was carried oat in seed technology laboratory, field crops department, College of Agriculture, Baghdad University of Aljadiriya for period of tow years. Seeds of three oat cultivars (Shifaa, Hamel and Pimula) taken from a field experiment conducted during 2014-2015 and 2015-2016 irrigated with three salinity water levels (3, 6 and 9 dS.m-1 ) in addition to river water with salinity level of 1.164 dS.m-1 as control. Seeds were tested in laboratory experiments to estimate their quality, and completely randomized design with three replicates was used. Statistic
