The game of handball is a group of games characterized by a variety of basic skills
offensive and defensive, and varied plans, whether in the attack or defense, it is worth
mentioning that all movements of the attack aimed at finishing the correcti
on against the
opposing team, which is one of the most important duties in the practice of handball and
stop The result of the match on the accuracy of the technical performance of this skill. This
is what called for the selection of the skill of correction in this study because of its
importance, and that it is considered a key skills players in this game.
The research sample consisted of (12) young players from the center of Lattakia
Governorate. The experimental method was used in a group style.
The aim of the research is to prepare qualitative exercises to improve the accuracy of the
skill of the correction and to identify the role of the exercises in the development of the
skill level of correction, which can give positive results after application.
Where the sample was subjected to tribal testing to measure accuracy in the skill of
correction and then applied a set of specific exercises aimed at developing the skill of
correction and then telemetry when the completion of the exercise.
In comparing the tribal and remote measurements of the sample, the results of the study
showed that the specific exercises used in teaching and developing the skill of accuracy of
the correction of the base resulted in a significant improvement in the level of the research
sample.
The study recommended the use of training programs based on scientific foundations in the
development of skillful performance in handball. And the need to use targeted and
organized exercises and take into account the age groups and skill level when using
exercises to develop the skill of correction.
This study aims is to analyze the effect of spatial accuracy of the control points on the
images geometric correction accuracy, and this is done by applying tests on the same
image (IKONOS), where polynomial transformations were applied using sets
of control
points, each with absolute accuracy different from the other. These points were
extrapolated from a 1/1000 topographic map and from a georeferenced MOMS satellite
image with geometric accuracy of 2m and measured by GPS. The study showed that it is
possible to obtain the most accurate geometric correction by using control points with
absolute accuracy close to the spatial resolution of the image. It also showed that the use of
more precise control points would not ameliorate the accuracy of the geometric correction,
because the measurement of these points on the image is limited by its spatial resolution.
This research aims to show the importance of ensuring the
competence of all who operate specific equipment, perform tests
and/or calibrations, evaluate results, and sign test reports and
calibration certificates.
This research aims to present the importance of using statistical methods while establishing a quality
management system in the laboratory according to the requirements of the international standard ISO
17025:2005.
In addition the research describ
es how statistical analysis of the tests results works and includes a
practical study to evaluate the technical competence of the laboratory by using the most common
statistical methods (hypothesis testing) to study the results in a scientific way enables researchers to
identify weaknesses in the laboratory performance, and thus provides it with feedback and technical
advice helping to determine measurement problems and to check the Trueness of tests results.
Finally, the research provides recommendations and proposals such as a necessity of applying practical
methods for monitoring the performance of tests , making sure they meet quality requirements in terms of
trueness and precision , and working to remove the causes that affect the quality of performance during
all phases of testing, these proposals would – if they have been applied – support the laboratory to obtain
the certification in accordance with international standard ISO 17025:2005.
