Remodeling Teachers' and Students' Roles in Self-directed Learning Environments: The Case of Saudi Context

Traditional classrooms are markedly teacher-centered. EFL learners are largely urged to commit themselves to communicative learning environments which help them enhance their language performance. Self-directed learning is one of the approaches which proved to be highly effective in Foreign Language Learning (FLL). EFL teachers are usually encouraged to adopt self-directed learning practices in order to improve students’ linguistic competence and performance. Recently, many Saudi universities integrated self-directed learning mode into EFL instruction. However, students' language performance, which is crucial to finding a job opportunity in labor market, is below the desired level. The study aims at remodeling teachers' and students' roles in light of students’ perceptions of English self-directed learning. To achieve this ultimate goal, a questionnaire survey is administered and follow-up semi-structured interviews are held. Results showed that both male and female students have generally positive attitudes towards self-directed learning. However, many of them have real problems with understanding the nature of self-directed learning and how they should use it effectively. Therefore, both institutions and teachers are recommended to improve students’ understanding and awareness of self-directed learning modes, and to rethink their roles

Effectiveness of an Educational Program on University Collegians’ Perceptions of Healthy Exercise pattern

To find out the effectiveness of an educational program on university students' perceptions of a healthy exercise pattern. A quasi-experimental study to find out the exercise pattern of Mosul University students for the period from 9th November 2022 to 2nd January 2023, the sample of (60) students. The questionnaire consists of two parts: a part that measures social and demographic information and includes (6) items, and a part that measures healthy lifestyle data with regard to exercise pattern and includes (10) items. Determine the validity of the content of the questionnaire by presenting it to experts and using the half-division technique and calculating the Pearson correlation coefficient to determine the validity. The results of the data showed that all (60) students in the study sample did not have an adequate level of perception of the healthy physical activity pattern in the pre-test, while the results of the post-test after implementing the program were high, which shows that there is an improvement in their perceptions of the healthy physical activity pattern.The study showed that there was an improvement in perceptions of a healthy lifestyle related to exercise pattern in the study group compared to those in the control group.The study recommended the need to develop educational programs, lectures, courses and seminars on the benefits of a healthy exercise pattern that university students must follow to increase their perceptions that lead to changing their lifestyle and getting rid of wrong behaviors and habits

The Counselor Brent Scowcroft and his Role in Achieving the Requirements of the American National Security

      Despite the multiplicity of institutions contributing to the decision-making process in the United States of America, they interact to crystallize positions regarding international and strategic situations. The formulation of the national security policy depends on a number of institutions that complement each other in order to achieve an advanced security situation. Thus, the decision reflects the process of interaction of the existing regulatory institutions. This is because the essence of the national security and achieving its requirements also stems from the existence of a coherent system of shared beliefs and principles in the American society. Besides, these elements are the bases for achieving security. Researching about Brent Scowcroft’s role in meeting the requirements of the united States’ national security, it has been found necessary to include two pivots to the study. The first pivot discusses the requirements of achieving the national security of the United States of America, whereas the second pivot tackles Brent Scowcroft’s role, through the mechanisms of the national security council, in achieving the national security requirements in particular within the decision-making process in the history of the contemporary American political system. As for the type of the study, it is a historical study within the axis of contemporary American politics, while the methodology of the study came within the scientific analysis and according to the narrative and descriptive historical approach. This is because the research problem emphasizes the identification of the security and military requirements in order to achieve the integration of the national security of the United States. Finally, the conclusions have verified the National Security Adviser’s prominent role of during the Scowcroft era, in conducting partnership with the Ministry of Foreign Affairs in the decision-making process. The latter has said to affect the overall foreign policy and achieve the national security requirements of the United States of America at the end of the last century

Investigating the effects of cement and cement kiln dust as a filler on the mechanical properties of cold bituminous emulsion mixtures

The application of cold mixes is lagging behind in the research field, which is quite obvious in a developing country. Furthermore, cold mixes have more economic and environmental advantages than hot mixes. This is the principal motivation for the present research, which aims to improve the mechanical properties of cold mix asphalt. Ordinary Portland cement (OPC) and cement kiln dust (CKD) were used as filler in cold bituminous emulsion mixtures (CBEMs) to compare the obtained results with those for CBEMs with conventional limestone. Indirect Tensile Stiffness Modulus (ITSM), fatigue, and resistance to rutting tests were used in the comparison. The experimental results showed that CBEMs with CKD and OPC had comparative mechanical properties to CBEMs with limestone and hot mix asphalt of the same grading and materials. Thus, this research introduces a new cold mix with CKD or OPC, which is able to meet more than the mechanical characteristics' requirements, reduce costs, and provide environmental benefits. © IAEME Publication

A pilot study on automated quantitative grading of facial functions

Quantitative grading of facial paralysis (FP) and the associated loss of facial function are essential to evaluate the severity and to track deterioration or improvement of the condition following treatment. To date, several computer-assisted grading systems have been proposed but none have gained widespread clinical acceptance. There is still a need for an accurate quantitative assessment tool that is automatic, inexpensive, easy to use, and has low inter-observer variability. The aim of the authors is to develop such a comprehensive Automated Facial Grading (AFG) system. One of this system’s modules: the resting symmetry module has already been presented. The present study describes the implementation of the second module for grading voluntary movements. The system utilizes the Kinect v2 sensor to detect and capture facial landmarks in real time. The functions of three regions, the eyebrows, eyes and mouth, are evaluated by quantitatively grading four voluntary movements. Preliminary results on normal subjects and patients are promising. The AFG system is a novel system that is suitable for clinical use because it is fast, objective, easy to use, and inexpensive. With further enhancement, it can be extended to become a virtual facial rehabilitation tool
