Ask ChatGPT about the research

The use of kinetic analysis adopted by the biomechanics is significant because it may help to detect the mistakes associated with performance by determining the variables values that represent performance specifications, or to identify and address the weaknesses, or to add more active means and aids to develop the performance. This study focuses on the javelin release speed variable and its relation to the achievement. The study applied on 5 Syrian javelin throwers of national team who participated in Arab and Asian championships. The study concluded that there issignificant correlation between the javelin release speed and the achievement. The study also concluded the low release speed of the javelin compared with international champions. The researcher recommended to give more attention to the development of the javelin release speed and to improve the relevantvariables, and not to adopt the random assessment in determining the reasons of the low level.

Research summary
تسلط هذه الدراسة الضوء على أهمية استخدام التحليل الحركي في علم الميكانيكا الحيوية للكشف عن الأخطاء وتحسين الأداء في رياضة رمي الرمح. تركز الدراسة على متغير سرعة انطلاق الرمح وعلاقته بالإنجاز، حيث أجريت على خمسة رماة رمح سوريين من المنتخب الوطني الذين شاركوا في بطولات عربية وآسيوية. أظهرت النتائج وجود علاقة ارتباط معنوية بين سرعة الانطلاق والإنجاز، مع انخفاض مستوى سرعة انطلاق الرمح مقارنة بالأبطال العالميين. توصي الدراسة بضرورة التركيز على تحسين سرعة الانطلاق والمتغيرات المرتبطة بها، وعدم الاعتماد على التقييم العشوائي لتحديد أسباب التدني في الأداء. استخدمت الدراسة منهجية وصفية بأسلوب العلاقات الارتباطية، وشملت عينة البحث خمسة رماة من المنتخب السوري. تم استخدام كاميرا تصوير وبرمجيات التحليل الحركي لتحليل الأداء واستخراج المتغيرات. أظهرت النتائج أن زيادة سرعة الانطلاق تؤدي إلى تحسين الإنجاز، وأوصت الدراسة بضرورة استخدام التحليل الحركي لتحسين الأداء والتركيز على التناسق في التسلسل الحركي.
Critical review
تعد هذه الدراسة خطوة مهمة في فهم العلاقة بين سرعة انطلاق الرمح والإنجاز، إلا أنها تقتصر على عينة صغيرة من خمسة رماة فقط، مما قد يؤثر على تعميم النتائج. كما أن الدراسة لم تتناول بالتفصيل العوامل النفسية والاجتماعية التي قد تؤثر على أداء الرماة. كان من الممكن أن تكون الدراسة أكثر شمولاً لو تضمنت مقارنة مع رماة من دول أخرى أو تناولت تأثير برامج تدريبية مختلفة على سرعة الانطلاق. بالإضافة إلى ذلك، كان من الممكن أن تستفيد الدراسة من استخدام تقنيات تحليل حركي أكثر تطوراً للحصول على نتائج أكثر دقة.
Questions related to the research
  1. ما هي العلاقة بين سرعة انطلاق الرمح والإنجاز لدى رماة الرمح السوريين؟

    أظهرت الدراسة وجود علاقة ارتباط معنوية بين سرعة انطلاق الرمح والإنجاز، حيث أن زيادة سرعة الانطلاق تؤدي إلى تحسين الإنجاز.

  2. ما هي التوصيات التي قدمتها الدراسة لتحسين أداء رماة الرمح السوريين؟

    أوصت الدراسة بضرورة التركيز على تحسين سرعة الانطلاق والمتغيرات المرتبطة بها، واستخدام التحليل الحركي لتحديد طبيعة الأداء والعلاقة بين المتغيرات، وعدم الاعتماد على التقييم العشوائي لتحديد أسباب التدني في الأداء.

  3. ما هي المنهجية التي استخدمتها الدراسة لتحليل أداء رماة الرمح؟

    استخدمت الدراسة منهجية وصفية بأسلوب العلاقات الارتباطية، وشملت عينة البحث خمسة رماة من المنتخب السوري. تم استخدام كاميرا تصوير وبرمجيات التحليل الحركي لتحليل الأداء واستخراج المتغيرات.

  4. ما هي العوامل التي تؤثر على سرعة انطلاق الرمح وفقاً للدراسة؟

    تؤثر عدة عوامل على سرعة انطلاق الرمح، منها التكنيك الحركي للرامي، القوة العضلية، التناسق في التسلسل الحركي، والاحتكاك بالأرض. كما أن الأوضاع الجسدية أثناء الحركة مثل هيلان الجسم إلى الخلف ودوران الجزء العلوي تؤثر على سرعة الانطلاق.

Specialists use many methods to achieve their aimes .These methods help to detect and correct errors ,in addition to identifying and addressing the weaknesses ,or to add more effective tools and aids in order to develop the performance . The kinet ic analysis methods adopted by the biomechanics are considered one of the best and most effective methods which help detecting the errors associated with the performance through evaluating the variables representing the performance specifications. This study focuses on the determining the values of the pelvis speed , and stretched bow speed as variables and the speed of Javelin launching and studying the relation between them. This study applied on five Syrian Javelin throwers from the national team who participated in Arab and Asian championships. The study concluded that there was a significant correlation between the speed of pelvis and the launching speed , and there was no significant correlation between the speed of stretched bow and the launching speed neither between the speed of pelvis and the speed of stretched bow. In additionto the low level of the javelin speed lower than world champion's level .There is a weakness in the using of the kinetic transport and in taking advantage from the forces resulting from approach .
The present study aimed to find out the fourth grade pupils trends of basic education towards the unit is designed in accordance with the expansion Elaboration theory in Social Studies and its relation to their academic achievement , The research er analyzes the content of the first three units to book social studies for students in the fourth grade of primary education, and re-organize content according to the steps Elaboration theory expansion, and teacher preparation guide on the basis of the proposed olive model in design education, and testing of academic achievement and gauge students' attitudes towards expansion theory, and after confirmation of the validity and reliability of the tools, the researcher applied to a sample of 30 pupils, and the study results that pupils trends about expansionist theory was positive and that there are no differences in the students' attitudes towards unit designed according to Elaboration theory expansion due to the variable Gender (Male, Female) and that there is a statistically significant between pupils trends link towards unit designed according to the expansionist theory and academic achievement.
Serviceability is an indicator that represents the level of service a pavement provides to users. This indicator is obtained by a rating made by the users, we called it Present Serviceability Rating (PSR), or by measuring on the pavement’s surface then its called a Present Serviceability Index (PSI). In this research we make a physical measurements to the distresses of pavement’s surface, and use the collected data to calculate (PSI) according to the AASHTO design method. We selected three highways as a field study: (Damascus–Lebanon Border, Damascus– Jordan Border, and Damascus – Homs). Also we made a rating by evaluating user’s opinions to a questionnaire in order to get (PSR) and find the Relationship between (PSI),(PSR), then we measured the roughness of this selected roads to obtain the International Roughness Index (IRI), finally we used the results to define the relationship between (PSR ),( IRI) and the accepted value of (IRI) within The Syrian conditions.
This research aims at present to detect the relationship between Achievement Motivation and Aggressive behavior among a sample of first-grade students of secondary , and the study of the differences between the sexes ( male and female ) in the resear ch variables ( achievement motivation, aggressive behavior). And the research community of the secondary schools of government in the city of Jaramana , who are students in the first grade of secondary ( 15-17 years) , has been withdrawn sample randomly , which amounted to (100 ) students (50 males +50 females) , and the researcher used the following tools: 1 - a measure of achievement motivation, 2 - a measure of aggressive behavior, after that she has tested Validity and reliability, The researcher followed the descriptive analytical method so as to its relevance to the nature of the research, she has developed a set of hypotheses and Results came as following : 1 - The total prevalence of aggressive behavior in the first grade of secondary moderately. 2- The total prevalence of achievement motivation in the first grade of secondary hilgly 3There is a statistically significant relationship between the aggressive behavior and achievement motivation among a sample Search . 4 - There were statistically significant differences in the aggressive behavior depending on gender for the sample of the male.5 - There are statistically significant differences in self-concept depending on the gender for the sample of the females. In light of these results the researcher presented a set of proposals was the most important for further studies and research on aggressive behavior and its relationship to some psychological variables in the various stages of education (primary , university ) and the need to develop outreach programs designed to give teenagers the methods proper to learn positive behaviors correct and that lead help raise the level of motivation to accomplish them.
