مهارات إدارة الوقت وعلاقتها بقلق الاختبارات لدى طلبة كلية التربية الرياضية في جامعة اليرموك

هدف المقال التعرف إلى مستوى مهارات إدارة الوقت وعلاقتها بقلق الاختبارات لدى طلبة كلية التربية الرياضية في جامعة اليرموك تبعاً لمتغيرات (الجنس والسنة الدراسية).تم استخدام المنهج الوصفي والمنهج الارتباطي، وتكونت عينة الدراسة من (377) طالباً وطالبة ممن هم على مقاعد الدراسة للفصل الدراسي الثاني من العام الجامعي 2021/2022، تم اختيارهم بالطريقة الطبقية العشوائية، تم جمع البيانات باستخدام مقياس إدارة الوقت المصمم من قبل (Britton and Tesser, 1991) المكون من (35) موزعة على ثلاثة مجالات هي (التخطيط قصير المدى، والموقف من الوقت، والتخطيط طويل المدى)، ومقياس قلق الاختبار المعرفي المصمم من قبل (Núñez-Peña, 2016) المكون من (14) فقرة. أظهرت النتائج بأن مستوى مهارات إدارة الوقت لدى عينة الدراسة جاءت بدرجة متوسطة على المقياس ككل، ومستوى قلق الاختبار لدى عينة الدراسة جاء بدرجة متوسطة، وعدم جود فروق ذات دلالة إحصائية في مستوى مهارات إدارة الوقت وقلق الاختبارات لدى عينة الدراسة تبعا لمتغيري الجنس والسنة الدراسية، كما أظهرت النتائج وجود علاقة ارتباطية ذات دلالة احصائية سلبية بين مهارات إدارة الوقت وقلق الاختبار لدى طلبة كلية التربية الرياضية في جامعة اليرموك. أوصى الباحثون بعقد ورش تدريبية للطلبة لتطوير مهاراتهم في إدارة الوقت، وتخصيص جلسات ارشادية خلال الفصول الدراسية للطلبة الذين يتعرضون لقلق الاختبار المفرط كإجراءات وقائية للتعامل مع مواقف وقلق الاختبارات. The article aimed to identify the level of time management skills and its relationship with test anxiety among physical education students at Yarmouk University in light of various variable such as gender, university, and number of playing years. The study used the descriptive correlational method. The sample consisted of (377) male and female students who are studying for the second semester from the academic year 2021/2022. The time management scale which was adopted by B. Britton and A. Tesser included (35) items, distributed to three dimensions: short-range planning, time attitudes, long-range planning, and cognitive test anxiety scale which was adopted by M. Núñez-Peña, M. Suárez-Pellicioni and R. Bono included (14) items was as a tools for collection. The study showed that the level of time management skills of the study sample was moderate on the fields as a whole and the level of cognitive test anxiety of the study sample was moderate and that there were statistically significant negative between the levels of time management skills with anxiety among physical education students at Yarmouk University. The study recommend the necessity of necessity of enhancing time management skills through the use of sports management experts in holding training workshops on how to plan time management to develop students\u27 skills and modify their attitudes in dealing with time wastes

Neural Network Prediction Model to Explore Complex Nonlinear Behavior in Dynamic Biological Network

Organism network systems provide a biological data with high complex level. Besides, these data reflect the complex activities in organisms that identifies nonlinear behavior as well. Hence, mathematical modelling methods such as Ordinary Differential Equations model (ODE's) are becoming significant tools to predict, and expose implied knowledge and data. Unfortunately, the aforementioned approaches face some of cons such as the scarcity and the vagueness in the biological knowledge to expect the protein concentrations measurements. So, the main object of this research presents a computational model such as a neural Feed Forward Network model using Back Propagation algorithm to engage with imprecise and missing biological knowledge to provide more insight about biological systems in organisms. Therefore, the model predicts protein concentration and illustrates the nonlinear behavior for the biological dynamic behavior in precise form. Also, the desired results are matched with recent ODE's model and it provides precise results in simpler form than ODEs

Influence of Oral Dipping Tombak Smokeless Tobacco on Coagulation Profile and Platelet Counts

The goal of this paper is to investigate the influence of oral dipping of Tombak Smokeless Tobacco (SLT) on prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio(INR) values, and platelet counts (PLTs), in Sudanese Tombak users. An analytical cross-sectional study was conducted at Kosti health insurance hospital, Sudan, in 2019. According to the inclusion and exclusion criteria, 100 adult users of oral Tombak for three or more years were chosen randomly as a study group. Another 100 matched healthy individuals who never used Tombak were randomly selected as a comparative group. Venous blood specimens were collected in ethylene diamine tetra-acetic acid (EDTA) containers for the PLT counts using the automated haematology analyser (Sysmex, Tokyo, Japan XK-21SYSMEX) and in trisodium citrate anti-coagulant containers for coagulation tests using a co-agulometer machine analyser. Our findings show a significant decrease in PLT count mean values in the Tombak users group (212.1 × 103/mm3 ± 74.3 × 103/mm3) compared with the non-taking Tombak group mean values (243.2 × 103/mm3 ± 83.0 × 103/mm3), (p p p p p < 0.001). In conclusion, using Tombak a Smokeless Tobacco (SLT) for a long period significantly affect Platelet counts and coagulation profile
