تأتي أهمية استخدام وسائل التحليل الحركي التي يعتمدها علم الميكانيكا الحيوية في المساعدة على كشف الأخطاء التي ترافق الأداء من خلال تحديد قيم المتغيرات التي تمثل مواصفات الأداء ، أو لتحديد نقاط الضعف و معالجتها ،أو اضافة وسائل و معينات أكثر فاعلية لتطوير الأداء و تركز هذه الدراسة على تحديد قيم متغير سرعة انطلاق الرمح و علاقته بالإنجاز ، و قد طبقت الدراسة على 5 رماة رمح سوريين من أعضاء المنتخب الوطني و الذين شاركوا في بطولات عربية و أسيوية. و قد توصلت الدراسة إلى وجود علاقة ارتباط معنوية بين سرعة الانطلاق و الانجاز لدى رماة الرمح السوريين و انخفاض مستوى سرعة انطلاق الرمح و تدنى هذا المستوى عن المستوى الذي حققه الأبطال العالميين. و من أهم التوصيات التي أوصت بها الباحثة إعطاء حيز كبير من الاهتمام لتنمية سرعة الانطلاق و تحسين المتغيرات ذات الارتباط بها و عدم اعتماد التقييم العشوائي في تحديد أسباب التدني أو انخفاض المستوى.
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.

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.
This the study aimed to reveal the relationship between the
post- Traumatic stress and academic achievement of students
at the fifth and sixth grade in Salamiah city.
The study sample consisted of (200) students from the fifth
and sixth grade in
Salamiah city and that of the male and
female.
The researcher used: The scale of post-Traumatic Stress
Disorder of preparation Manal el-Sheikh (2010), and had a
good degree of validity and reliability
The research found the following results:
1 - Find a sample children's exposure to PTSD after
traumatic experiences they went through.
2 - There were statistically significant differences between
the average degrees of exposure to PTSD variable depending
on sex.
3 - There is a statistically significant relationship between
exposure to traumatic stress and academic achievement.
