أن لعبة الكرة الطائرة هي واحدة من االلعاب الرياضية الجماعية التي طرأت عليها تطورات كبيرة على المستوى المهاري والبدني مما انعكس ذلك على تطور أساليب اللعب والخطط والقوانين التي ساهمت في إعطاء جمالية في أداء الالعبين وزيادة إثارة حماس الجماهير، ولهذا جاءت فكرة الباحثون في كونه يساعد على الكشف عن الرضا الحركي والذات الجسمية والذين يؤثران وبدرجة كبيرة على ممارسة األنشطة الرياضية من أجل تحقيق نتائج رياضية أفضل فضال" عن تحديد الدرجات والمستويات المعيارية التي يستفيد منها العاملون في مجال الكرة الطائرة، فمن خالل تفهم الالعب لمستوى الرضا الحركي والذات الجسمية والذي يؤدي إلى شعور العب الكرة الطائرة باالرتياح والسعادة والدافعية العالية لإلقدام على التدريب وهذا بدوره يؤدي إلى التغلب على كثير من الصعوبات التي تواجه الالعبين عند عملية التدريب والممارسة ويساهم في المثابرة نحو االستمرار في مزاولة األنشطة األمر الذي دفع الباحثون إلى دراسة موضوعا الرضا الحركي والذات الجسمية لمعرفة وتحديد الدرجات والمستويات المعيارية لدى العبي كرة الطائرة المتقدمين. فيهدف البحث الى: التعرف على الرضا الحركي والذات الجسمية لالعبي الكرة الطائرة المتقدمين. واستخالص الدرجات والمستويات المعيارية لمقياسي الرضا الحركي والذات الجسمية. ولتحقيق هذه االهداف أستخدم الباحثون المنهج الوصفي بأسلوب المسحي لمالئمة طبيعة مشكلة البحث. اشتمل مجتمع البحث على العبي اندية النخبة بالكرة الطائرة موزعين على )6( اندية )الشرطة – غاز الجنوب – البحري – البيشمركة – الحبانية- ( العباً الكوفة( والبالغ عددهم )08( العبا، أذ اختار الباحثون )08 يمثلون عينة البحث بالطريقة العمدية ويشكل هذا العدد ما نسبته )%07( من المجتمع االصل، اما الالعبين المتبقين من المجتمع قام الباحثون باستبعادهم ألجراء التجربة االستطالعية عليهم وقسم الباحثون العينة كاالتي: )08( العب تجربة األسس العلمية لمقياسي الرضا الحركي والذات الجسمية، و )08( العبا عينة التجربة الرئيسة فضال عن استخدام الباحثون لمقياسي الرضا الحركي والذات الجسمية لمحمد حسن عالوي وقام الباحثون بالتحقق من صالحية المقاييس ام الباب الرابع فقام الباحثون باستخراج الدرجات والمستويات المعيارية للمقاييس. أذ استنتج الباحث: ان استخدام )7( مستويات معيارية للمقياسين دل على عدم تشتت الدرجات. وتمتع العبي الكرة الطائرة بمستوى جيد من الرضا الحركي ومتوسط من الذات الجسمية. وبعدها أوصى الباحثون بعدة توصيات منها: االهتمام بدراسة متغيرات نفسية أخرى لالعبي الكرة الطائرة. واجراء دراسات اخرى على فعاليات رياضية اخرى
Longer follow-up defense , one of basketball skills that require the team collective action involving active part and consistent to acquire bouncing balls even not be a chance for members of the team striker acquisition rebounding from the target area and bring it back again , which reduces the chances of scoring, and it enables team members defender of the performance of fast attack and score points for being the increase your chances of success.In light of the foregoing, reflected the importance of research in achieving the objective basis of skill tests that require a circumstance similar to the circumstances of the game with the standard operating procedures for the registration, and that the validity judged by consistency between tests

The method of estimating the distribution parameters for each device was the OLS method.
The main objective of this research is to determine the optimal time for preventive maintenance of medical devices. Two methods were adopted to estimate the optimal time of preventive maintenance. The first method depends on the maintenance schedule by relying on information on the cost of maintenance and the cost of stopping work and acc

This study investigated the optimization of wear behavior of AISI 4340 steel based on the Taguchi method under various testing conditions. In this paper, a neural network and the Taguchi design method have been implemented for minimizing the wear rate in 4340 steel. A back-propagation neural network (BPNN) was developed to predict the wear rate. In the development of a predictive model, wear parameters like sliding speed, applying load and sliding distance were considered as the input model variables of the AISI 4340 steel. An analysis of variance (ANOVA) was used to determine the significant parameter affecting the wear rate. Finally, the Taguchi approach was applied to determine

One of the most important and useful applications of guide robots is the support of the blind. The successful implementation of this study requires a more accurate and powerful self-localization system for guide robots in indoor environments. This paper proposes a self-localization system for guide robots. To successfully implement this study, images were collected from the perspective of a robot inside a room, and a deep learning system such as a convolutional neural network (CNN) was used. An image-based self-localization guide robot image-classification system delivers a more accura

The smartphone application on an Android platform applies the location sensing run as a background process and the localization method is based on cell phones. The proposed application is associated with remote server and used to track a smartphone without permissions and internet. Mobile stored data location information in the database (SQLite), then transfer it into location AP

Show MoreSurvival analysis is one of the types of data analysis that describes the time period until the occurrence of an event of interest such as death or other events of importance in determining what will happen to the phenomenon studied. There may be more than one endpoint for the event, in which case it is called Competing risks. The purpose of this research is to apply the dynamic approach in the analysis of discrete survival time in order to estimate the effect of covariates over time, as well as modeling the nonlinear relationship between the covariates and the discrete hazard function through the use of the multinomial logistic model and the multivariate Cox model. For the purpose of conducting the estimation process for both the discrete
