HOW TO GET HIGHER QUALITY SCHOOL PHYSICAL EDUCATION WITH A RETROSPECTIVE ON STANDARDS IN EDUCATION?

There is no improvement in the quality of school physical education without establishing standards in education. Basic problems, questions, and models of effective teaching of physical education (PE) are presented. The goal of this topic is that after the adoption of the standards, the professional public gets to know, prepare, and activate them for their application in practice. Through a comparative analysis of the valid goal and program of physical education for primary education, recommendations for the way of implementation, and characteristics of educational standards for primary education and upbringing, educational goals and tasks are made concrete through student achievements - visible outcomes in behavior and reasoning. This is the answer to the question of how to achieve better effects and increase the quality of physical education, the capacities we have at our disposal. Focus on: competence in skills, knowledge in physical exercise and physical education and evaluation of physical exercise and physical education by students, standards that objectify assessment and grades, make them comparable and provide a basis for developing instruments for self-evaluation. One of the significant contributions to the achievement of teaching in accordance with educational standards is the activation of teachers, students, parents, the school and the local community. Dilemmas were raised in connection with specific problems in the educational field of physical education, and above all the conditions for the implementation of the physical education program, as well as the implementation of teaching content, within the first cycle of basic education, which directly reflect on the possibility of reaching the standard by the end of the mandatory of education.  Article visualizations

Validity And Realibility Of The Knowledge, Attitude And Practice (Kap) Questionnaire On Hexagonal And Olympic Barbell Deadlift Among Young University Students

An instrument for assessing the Knowledge, Attitude, and Practice (KAP) regarding hexagonal and Olympic barbell deadlift among young university students is crucial for identifying any gaps in KAP. This assessment can assist in developing specific educational interventions, enhancing training programs, improving overall strength and conditioning outcomes, and mitigating health risks. The objective of this study was to create and verify a questionnaire, specifically designed for young university students, that assesses knowledge, attitudes, and practices (KAP) related to hexagonal and Olympic barbell deadlift exercises. A study employing purposive sampling was undertaken among a cohort of 242 young university students in Malaysia. This questionnaire was derived from a previous study and enhanced with additional components related to hexagonal and Olympic barbell deadlift. The verification of content validity, construct validity, and reliability was conducted utilising several tests. All the items in the questionnaire contribute to a minimal factor structure, as indicated by the results of a rotational component matrix. The Kuder-Richardson 20 (KR-20) coefficient for the knowledge domain was 0.73, which is regarded satisfactory. The Cronbach\u27s Alpha values above 0.70, indicating strong reliability. However, they were lower than the overall Cronbach\u27s Alpha value of 0.965 for the practice domain. Therefore, no item needed to be removed. This questionnaire demonstrates robust validity and reliability, making it suitable for assessing knowledge, attitudes, and practices related to hexagonal and Olympic barbell deadlift

Galactic and Extragalactic Samples of Supernova Remnants: How They Are Identified and What They Tell Us

Supernova remnants (SNRs) arise from the interaction between the ejecta of a supernova (SN) explosion and the surrounding circumstellar and interstellar medium. Some SNRs, mostly nearby SNRs, can be studied in great detail. However, to understand SNRs as a whole, large samples of SNRs must be assembled and studied. Here, we describe the radio, optical, and X-ray techniques which have been used to identify and characterize almost 300 Galactic SNRs and more than 1200 extragalactic SNRs. We then discuss which types of SNRs are being found and which are not. We examine the degree to which the luminosity functions, surface-brightness distributions and multi-wavelength comparisons of the samples can be interpreted to determine the class properties of SNRs and describe efforts to establish the type of SN explosion associated with a SNR. We conclude that in order to better understand the class properties of SNRs, it is more important to study (and obtain additional data on) the SNRs in galaxies with extant samples at multiple wavelength bands than it is to obtain samples of SNRs in other galaxiesComment: Final 2016 draft of a chapter in "Handbook of Supernovae" edited by Athem W.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic

Ablation of residual potentials along the circumferential line reduces acute pulmonary vein reconnection

Introduction: Acute pulmonary vein (PV) reconnection is frequently encountered in patients undergoing PV isolation (PVI) procedure for the treatment of atrial fibrillation. In this study, we investigated whether the identification and ablation of residual potentials (RPs), after the initial achievement of PVI, reduces acute PV reconnection rate. Methods: Following PVI in 160 patients, mapping along the ablation line was performed to identify RPs, defined as bipolar amplitude ≥0.2 mV or 0.1-0.19 mV combined with a negative component of the unipolar electrogram. Ipsilateral PV sets with RPs were randomized to either no further ablation (Group B) or to additional ablation of the identified RPs (Group C). The primary study endpoint was spontaneous or adenosine-mediated acute PV reconnection after a 30-min waiting period and was also evaluated in ipsilateral PV sets without RPs (Group A). Results: After isolation of 287 PV pairs, 135 had no RPs (Group A), whereas the remaining PV pairs were randomized to either Group B (n = 75) or Group C (n = 77). Ablation of RPs resulted in a reduction of spontaneous or adenosine-mediated PV reconnection rate (16.9% in Group C vs 48.0% in Group B; p < 0.001). Group A was associated with a significantly lower percentage of acute PV reconnection as compared to Group B (5.9% vs 48.0%; p < 0.001) and Group C (5.9% vs 16.9%; p = 0.016). Conclusion: After PVI achievement, the absence of RPs along the circumferential line is associated with a low likelihood of acute PV reconnection rate. Ablation of RPs significantly reduces spontaneous or adenosine-mediated acute PV reconnection rate
