تعتبر كرة القدم لعبة شعبية معروفة في جميع أنحاء العالم، وهناك العديد من المباريات تلعب يوميا بمختلف المستويات، ولقد فتن الناس بلعبة لا يمكن التنبؤ بنتائجها، ويمكن تحديد نتيجتها في ثوان معدودة عن طريق التحركات غير العادية للخصم أو الأخطاء الدفاعية القاتلة وغالبا ما يلعب حارس المرمى دورا حاسما في نتيجة المباراة ، حيث تعتمد كرة القدم بشكل اساسي على الامكانيات المهارية للاعبين واستغلال هذه الامكانيات بالشكل الامثل خلال التحركات والمناورات التي يقوم بها افراد الفريق بغرض تسجيل اكبر عدد من الاهداف واحراز الفوز، واصبح واضحا انه لابد من توفر المعلومات لدى المدرب عن الخصائص اللازمة لأداء المهارات المختلفة حيث اسهم التطور التكنولوجي في مجال التحليل الميكانيكي في الكشف عن العلاقات المتداخلة بين حركة اجزاء الجسم اثناء تأدية تلك المهارات والتي لايمكن الحصول عليها الا بمتابعة وتحليل حركة اللاعب اثناء مراحل اداء هذه المهارات، وان تطور المجال الرياضي مثله مثل كثير من مجالات النشاط الانساني قائم على تطور العلم ودقة المعلومات، فبدون المعلومات الدقيقة لن يستطيع الرياضي ان يتفاعل مع مدربه خلال الاداء الرياضي المطلوب، وعلى الرغم من أن بحوث كرة القدم واسعة النطاق، إلا أن البحوث المتعلقة بمهارات حارس المرمى وبيوميكانيكية حركاته تعتبر قليلة اذا ماقورنت مع بقية البحوث المتعلقة بالجوانب الاخرى لكرة القدم ، وهكذا، فإنه يبدو مناسبا للبحث في مهارات حارس المرمى بمزيد من التفصيل، حيث يعتبر حارس المرمى العمود الفقري للفريق بسبب المركز الذي يشغله والذي يتطلب منه الدفاع عن مرماه بطريقة متميزة وفعالة ، إذ ان طبيعة المباريات تتطلب أن يمتاز حارس مرمى كرة القدم بمهارات اساسية خاصة، وذالك نتيجة للدور الهام الذي يؤديه والذي يمكنه من الدفاع عن مرماه بإستخدام يداه داخل منطقة الجزاء، وأن طبيعة المباراة تستدعي منه القيام بالأداء المهاري والخططي بقوة وسرعة ودقة ، وحارس المرمى الذي كان يعتبر اخر خط دفاعي اصبح الآن في كرة القدم الحديثة عنصر هجومي هام تبدأ منه اغلب الكرات المرتدة والسريعة بسبب موقعه المتميز، ومن هنا تبلورت مشكلة البحث في توصيف مهارة ارتماء حارس المرمى للامساك بالكرة متوسطة الارتفاع في ضوء نتائج التحليل الكيفي والكمي للناشئين تحت 17 سنة وصولا الى فهم اعمق للاداء الفني والتعرف على نقاط الضعف وعلاجها من خلال اساليب التدريب المختلفة وبالتالي القدرة على تحسين وتوجيه العملية التدريبية وصولا للمثالية في الاداء
Geography of industry has been considered a branch of important economic geographical branches. This importance has been regarded as a reflection on the industrial sector contribution in economies of any state since they contribute into the total national product ; it also assimilates a huge number of labor hands . The industry of grains grinding has been considered as one of the main food industries having a main role in satisfying the need of the population from the foods. The industry is continued to use the food as daily meal . Here, it should predict the population in Baghdad and for every district until the end of 2025 and knowing either these grains grinders are able to meet and satisfy the needs of populations of flours, making s

The analysis was done by groups of health guide indicators. The objectives of the study were to identify the spatial variation of health services and assess the health situation for families following the environmental and administrative units of the studied area. Such objectives can be done by specifying the extent of the families’ consent to the type of services, measuring the cases of deprivation, and identifying the most deprived areas. The study has finally concluded that there is a clear spatial variation between the indicators and

The theoretical problem derived from the existence of a knowledge gap for studies and research that dealt with the variables of the study. Three public organizations were selected as the study society (the Civil Defense Directorate, the Directorate of Nationality, Passports and Residency, the General Traffic Directorate). The sample of the study was a sample of (215) managers (managers, department managers, Analysis of the data and hypothesis testing using the appropriate statistical tools, Pearson, the simple and multiple regression coefficient to te

The value chain analysis is main tools to achieve effective and efficient cost management; it requires a depth and comprehensive understanding for all internal and external activities associated with creating value. Supply chain as apart of value chain, that means managing it in active and efficient can achieve great results when adopting a comprehensive and integrated performance for these two chains activities. The research aims to identify possible ways to integrate the performance of value and supply chains of the sample" Kufa-cement plant" and determine the effect of this integration in enhancing customer value. The research arrival that logical and integrated analysis of value and supply chains helps

The research population is the people in the region, and a simple random sample of 332 individuals were selected. The factor analysis as a reliable statistical method in this phenomenon was used to modeling and testing the structural model of tourism, and analyzing the data by using SPSS and AMOS statistical computerized programs. The study reached a number of results, the most important of them are: the tourist attraction factors model consists of five factors which explain 69.3% of the total variance. These are: the provision of tourist services, social and historic factors, mountains, weather and natural parks. And the differenc

Consequently, the capabilities of mind maps were employed as a tool that would be through freeing each student to analyze a model of artistic work and think about his analytical principles according to what he knows. Then, a start-up with a new stage revolves around the possibility of transforming this analysis into a teaching style by thinking about how the student would do.

Show Morethe student of the structure of the city and its constituent elements will clearly sense the invisible relationships that underlie the different forms of urban activity, which in turn are defined by the generality of the urban patterns in that city, which will vary clearly according to the location in the city. These relations will be embodied in their true form in the interactions between the different uses of the earth, and the change that will result from their regularity in the form of entities in independent groups, which may share with each other a component of it.
Therefore, the process of controlling the functional interactions between the uses of the urban land and the awareness of t
The objective of this work is to study the influence of end milling cutting process parameters, tool material and geometry on multi-response outputs for 4032 Al-alloy. This can be done by proposing an approach that combines Taguchi method with grey relational analysis. Three cutting parameters have been selected (spindle speed, feed rate and cut depth) with three levels for each parameter. Three tools with different materials and geometry have been also used to design the experimental tests and runs based on matrix L9. The end milling process with several output characteristics is solved using a grey relational analysis. The results of analysis of variance (ANOVA) showed that the major influencing parameters on multi-objective response w

With new technologies, it is now possible to collect human-generated sounds, such as coughing. Audio-based machine learning technologies can be adopted for automatic analysis of collected data. Valuable and rich information can be obtained from the cough signal and extracting effective characteristics from a finite duration time interval that changes as a function of time. This article presents a proposed approach to the detection and diagnosis of COVID-19 through the processing of cough collected from patients suffering from the most common symptoms of this pandemic.
