Physical activities, resources and challenges in implementation of physical education programme among public primary schools in Kampala Uganda
Get PDFPhysical activities among young people provide an opportunity to develop the values, and skills for an active lifestyle and high self-esteem. Physical Education as one of the subjects in schools covers this essential role, although its’ provision mostly in the developing world has declined in many countries. This study assessed the physical activities, resources, and challenges in the implementation of Physical Education program among public primary schools in Kampala, Uganda. It was a descriptive survey design employing a semi-structured questionnaire to collect data among teachers and headteachers. Data were analyzed using frequencies, and Pearson product-moment correlation was determined at 0.05 level of significance. Findings reveal availability of facilities (r=0.374), trained personnel (r=0.654), equipment (r=0.529) and school enrolment (r=0.622) having a significant relationship with implementation of PE program. Traditional games, athletics, and ball games were the main activities. Insufficient resources and less value attached to these activities remain the major challenges. Resource allocation and sensitization on the value of physical education could enhance the implementation of the physical education program in public schools
ESP for economy and business: A critical needs analysis of English language teaching in today's market economy in Algeria
Get PDFSome decades ago, Algeria began a transformation from a planned economy to a market economy, for which English became a requirement. The Algerian government believes that promoting English language learning is an attempt to become competitive globally. This emphasis on English resulted in various curricular reforms, influenced by the economic globalization, as the nation attempted to shape its educational systems to provide the skills for a growing global economy. Through this contribution, we believe that contributors have to rethink the role of English in education, employment, social status, and financial development. Moreover, in pedagogy, it is better to shift from ESP to teaching TEGCOM (Teaching English for Globalized Communication), allowing interaction between global forces in specific socio-cultural contexts. Therefore, in working together, the Algerian contributors can prove their English ownership and exercise their agency in their different market creative practices
Analysis of Hybrid Technique for Motion Planning of Humanoid NAO
Get PDFThe navigation of a humanoid robot is essential because it is the basic requirement of any assigned task. Singly used motion planning techniques may take a long path to reach the target and increase the computational cost. Therefore, in this article, a hybrid controller is employed in the humanoid NAO for motion planning assignment. The Eagle strategy (ES) with Ant colony optimization (ACO) is introduced in this article for evaluating precise steering angles for humanoid robots as they traverse a route from a reference point to a target point. This enables the robot to achieve its specific target more quickly by avoiding barriers and obtaining the minimal global direction. The hybridized ES-ACO approach is critical in determining precise steering angles to escape obstacles. The details of terrain are obtained using vision and ultrasonic sensors, which also include the barriers ranges to the ES as an input variable. The ES's input parameters are the barrier ranges from the NAO in front, left, and right directions, and the technique's output variable is the precise steering angle. The designed controller is tested in both a simulation and an experimental setting with a variety of obstacles. The outcomes of both simulation and experimental conditions are compared, and a strong correlation is identified in those with the fewest deviations
Tuning of PID Controller Parameters with Genetic Algorithm Method on DC Motor
Get PDFProportional Integral Derivative (PID) controllers are used in general to control a system, for example a DC motor system. The difficulty of using the controller is parameter tuning, because the tuning parameters still use the trial and error method to find the PID parameter constants, namely Proportional Gain (KP), Integral Gain (KI) and Derivative Gain (KD). In this case, the genetic algorithm method is used which can give better results in each iteration. Genetic algorithms are one of the smart methods inspired by the process of natural selection, the process that causes biological evolution, this concept is applied to tuning PID parameters. This research uses the Matlab simulation method and applies the simulation results to the DC motor hardware using the Arduino Uno. The genetic algorithm method gives a system that has a better steady time and a smaller maximum spike than the Trial and Error method. The test process produced the two best data with an overshoot value = 2, settling time = 13.5 and rise time of 2.7872 and the PID parameter value for mutation of 1 was KP = 3.7500; KI = 1.3184 and KD = 0.2051. Then the value of the best PID parameter on Crossover is 0.4, which is KP = 4.2090; KI = 1.2012 and KD = 0.2539 with an overshoot value = 2, settling time = 18 and rise time = 2.6462
Priests’ communication practice and perception of code mixing in sunday sermons
Get PDFA number of studies on code-mixing have been extensively researched in educational communication; but few studies have explored the practice of code-switching in preaching, which is the domain of religious communication. The study aims to describe the practice of code-mixing in delivering sermons by pastors who use traditional language (Simalungun) as a medium of delivery. The study used a descriptive qualitative research approach with a survey research design using the google form platform as a research instrument, involving sixty priests as the study participants, using the Simalungun language as a medium for delivering sermons. The results of this study reveal that the motivation to use code-mixing is very important to clarify and facilitate the delivery and understanding of the content of the sermon. The results of this study also reveal the reasons, the dominant preaching genre using code-mixing, the language used in code-mixing, the problems faced in practicing code-mixing, as well as the congregation's perception of the practice of code-mixing carried out by pastors. The results of this study provide a complete description of the practice and perception of code-mixing in sermons using the Simalungun language. Further researches on the content of preaching in Sunday sermons using different methods of analysis are suggested by the study
A New Approach to Fault Detection in the Power Converter in Wind Turbine Conversion Systems
Get PDFThe detection of faults in a wind turbine chain is of prime importance in order to maintain safety, enhance reliability and improve economic performance. In addition, wind systems have to ensure a continuity of service for a considerable period of time in the event of an electrical fault in the network or a fault in one of the elements of the electromechanical conversion system. This paper presents a fault detection methodology of the power converter within a wind turbine chain, equipped with a Doubly-Fed Induction Generator (DFIG). A configurable, fast, and accurate scheme is developed, the basis of which is the reliable identification of the failed switch. The solution proposed in this work involves the deployment of a redundant arm in the event of a fault; the replacement arm is utilized while waiting for a maintenance or repair operation to be carried out. The approach developed in this paper provides continuity of service after the occurrence of a fault in the network system and fault detection time is reduced. The validity of the proposed identification methodology is assessed by means of simulation of the model of a wind turbine conversion system

The historical context of globalization in Egypt: Foreign professors’ migration to the Egyptian university (1908)
Get PDFAs a major offshoot of the national Egyptian movement that goes back to the beginning of the 20th century, a number of national leaders, Enlightenment pioneers, and social thinkers called for the establishment of an Egyptian university. These individuals hoped for this to be a lighthouse of liberal thought and the basis of a comprehensive academic revival in all fields of knowledge in order to be able to cope with international scientific and academic advancement. By May 1908, the Royal Palace chose the administrative council for the project of the Egyptian University (EU). When the university began, not a single Egyptian could meet all its ideal criteria for professors. The EU did borrow staff from the schools of law for its criminology, economics, and law programs. Dar al-Ulum constructed the university between 1908and 1925, which had at least nine professors. The other source of interim professors was Europe. The European professors fall into two categories: those who lectured in French or English on topics unrelated to the Middle East and the orientalists who lectured on Arabic and Islamic subjects. France, Italy, England, and, to a lesser extent, Germany all jockeyed for influence at the university. European professors dominated the first generation of faculty members while promising that Egyptian students were sent abroad to train for future teaching positions. In the present review, light will be shed on the large role played by those elite European professors in determining and pushing the university forward to stand with the Egyptian professors in order to examine the development of European-style education within the EU and, to a lesser extent, the cultural influence of a number of European countries in Egyptian education
How are important career services for Islamic college students?
Get PDFThe purpose of this study is to identify the importance of career services and career service delivery to Islamic college students. The implementation and importance of career services for each campus is different, depending on the direction of policy and leadership. The approach used in this research are a survey using a career service instrument that has been developed. Respondents of this study were 786 students from various departments and grades at UIN Sunan Kalijaga Yogyakarta Indonesia. The research findings indicate that 98.9% of each student needs career services in the form of adjustment to majors, development of potential and personal skills, and career preparation related to the world of work, while the implementation of career services that have been running is relatively different for each department and faculty. In the Tarbiyah and Teacher Training faculties, they get more career services with an average (103.6) such as getting great opportunities for their students to do internships before graduating, but in the ad humanities social sciences and humanities faculty with an average (89.1) they still need improvement of career services for students
A comparative analysis of cold war and post-cold war media framing of aviation disasters
Get PDFThis study builds on previous research that examined U.S. media coverage of two airline disasters – KAL007 and IR655 – during the Cold War in the 1980s. It explores new Cold War frames in The New York Times and The Moscow Times’ coverage of the downing of Malaysian Airlines Flight MH17 in 2014. Additionally, U.S. and Russian official narratives of the incident were compared to the MH17 coverage by the two selected newspapers. Results reveal an absence of hostile Cold War assertions but indicate a link between media frames and the U.S. and Russian government positions. Additionally, findings shed light on the Moscow-Washington relations against the backdrop of intense confrontation between Russia and the West not witnessed since the collapse of the Soviet Union
