The Impact of the Teacher’s Personality on the Motivation of Learning the English Language Among Governmental School Students in Saudi Arabia

The current study aimed to identify the impact of the teachers personality on the motivation of learning English among government school students in the city of Abha, Saudi Arabia. The descriptive correlative method was used, and two questionnaires were designed to collect the data. They were distributed electronically, and the study targeted a sample of English language teachers in public secondary schools in Abha, and a sample of high school students in Abha, who were chosen randomly in a simple way. The results of the study showed that English language teachers have personal characteristics that qualify them to teach in high government schools, with an average of (3.6918), which is considered as a highly - approved degree, and that students have a motivation to learn English with an average of (3.7828), which means they scored a high degree of approval. The results also showed the effect of the teachers personality on the motivation of students towards learning English. The results also showed that it is possible to predict the motivation of learning English through the teachers personality

ROLE OF THE PHYSICAL ACTIVITY IN THE IMPROVEMENT OF CARDIAC MEASURES AND DECLINING OF COMORBIDITIES.

Background: Regular physical activity (PA) can prevent many non-communicable diseases, such as cardiovascular disease (CVD) and diabetes mellitus (DM). The present study aimed to assess the health benefits of physical activities including blood pressure and comorbid conditions. Methodology: This is a prospective cohort case-control study that recruited 300 Saudi volunteers living in the city ofHail, Northern Saudi Arabia. Results: Out of 300 participants 155(51.7%) were males and 145 (48.3%) were females. There were 111(37%) participants committed to regular physical activity and the remaining 189(63%) without a defined commitment to physical activity (Uncommitted). Among 111 persons who claimed a commitment to regular physical activity (committed), 61(55%) were males and 50(45%) were females. The majority of committed individuals were at the age group 21-25 years followed by age group 26-30 and 31-35 years representing 32, 30, and 20 persons, respectively. The physical activity was highly practiced at the age range 21-30 years and this was found to be statistically significant P < 0.001. Conclusion: There is a low prevalence of physical activity in Hail region, particularly among females, which necessitates the suggestion of appropriate awareness programs. Younger and elder populations are in much need to be targeted with PA awareness programs

The Effect of Social Isolation on the Mental Health of International Students

This paper looks into how social isolation affects international college students mental health. An increase in international students studying at colleges and universities abroad can be attributed to increased global mobility over the previous few decades. Because of this, these students struggle in certain ways to fit into their new academic and social surroundings. Among these difficulties, social isolation among overseas students has been recognized as a major issue. This essay will investigate how social isolation affects the mental health of international college students by drawing on existing studies. The various types of social isolation will be covered in the essay along with how they may affect mental health. It will also be looked at whether factors like linguistic difficulties, cultural shock, prejudice, and discrimination contribute to social isolation among overseas students. In light of the hazards to mental health posed by social isolation among international students, this presentation will offer some potential solutions. The findings of the inquiry will be utilized to create solutions that can assist overseas students in reducing the detrimental impacts of social isolation on their mental health. Compared to other groups, college students’ mental health has not been adequately researched, even though social isolation can be an emotionally and mentally damaging experience. The paper will focus on the various mental health impacts that international college students experience such as depression, anxiety, and long-term psychological harm. An analysis of existing literature on the topic, interviews with international college students, and the mental health resources available to this population are also discussed. The main findings of the research show that international college students living in a foreign country experience significant levels of social isolation due to language barriers and cultural differences

Thermal characterization of date palm/epoxy composites with fillers from different parts of the tree

Thermal expansion and viscoelastic properties of the date palm fibre (DPF)/epoxy composites were influenced by the type of filler from different parts of the date palm tree. The variation in properties is mainly due to the difference in fibre composition between the DPF from leaf stalk, leaf sheath, fruit bunch stalk, and tree trunk. Among the investigated composites, composite reinforced with the tree trunk fibre displayed higher thermal stability as visible from the lower weight loss, higher onset and inflection temperatures and maximum residue % from the thermogravimetric analysis (TGA). Lower coefficient of linear thermal expansion (CLTE) obtained from thermomechanical analysis (TMA) further provided supportive evidence for dimensional stability at elevated temperature. Based on the dynamic mechanical analysis (DMA) results, the DPF/epoxy composites with fruit bunch stalk fillers displayed a better property by showing higher storage modulus and lesser tan delta values. Hence, composite from the tree trunk and fruit bunch stalk fibres of date palm is recommended for applications requiring superior thermal resistance

In Silicon Monte Carlo Simulation Trials for Investigation of V2O5 Reinforcement Effect on Ternary Zinc Borate Glasses: Nuclear Radiation Shielding Dynamics

In the current study, promising glass composites based on vanadium pentoxide (V2O5)- doped zinc borate (ZnB) were investigated in terms of their nuclear-radiation-shielding dynamics. The mass and linear attenuation coefficient, half-value layer, mean free path, tenth-value layer, effective atomic number, exposure-buildup factor, and energy-absorption-buildup factor were deeply simulated by using MCNPX code, Phy-X PSD code, and WinXcom to study the validation of ZBV1, ZBV2, ZBV3, and ZBV4 based on (100−x)(0.6ZnO-0.4B2O3)(x)(V2O5) (x = 1, 2, 3, 4 mol%) samples against ionizing radiation. The results showed that attenuation competencies of the studied glasses slightly changed while increasing the V2O5 content from 1 mol% to 4 mol%. The domination of ZnO concentration in the composition compared to B2O3 makes ZnO substitution with V2O5 more dominant, leading to a decrease in density. Since density has a significant role in the attenuation of gamma rays, a negative effect was observed. It can be concluded that the aforementioned substitution can negatively affect the shielding competencies of studied glasses. © 2021 by the authors. Licensee MDPI, Basel, Switzerland

Perceived responsibility for mechanical ventilation and weaning decisions in intensive care units in the Kingdom of Saudi Arabia

Background: Optimizing patient outcomes and reducing complications require constant monitoring and effective collaboration among critical care professionals. The aim of the present study was to describe the perceptions of physician directors, respiratory therapist managers and nurse managers regarding the key roles, responsibilities and clinical decision-making related to mechanical ventilation and weaning in adult Intensive Care Units (ICUs) in the Kingdom of Saudi Arabia (KSA). Methods: A multi-centre, cross-sectional self-administered survey was sent to physician directors, respiratory therapist managers and nurse managers of 39 adult ICUs at governmental tertiary referral hospitals in 13 administrative regions of the KSA. The participants were advised to discuss the survey with the frontline bedside staff to gather feedback from the physicians, respiratory therapists and nurses themselves on key mechanical ventilation and weaning decisions in their units. We performed T-test and non-parametric Mann-Whitney U tests to test the physicians, respiratory therapists, and nurses’ autonomy and influence scores, collaborative or single decisions among the professionals. Moreover, logistic regressions were performed to examine organizational variables associated with collaborative decision-making. Results: The response rate was 67% (14/21) from physician directors, 84% (22/26) from respiratory therapist managers and 37% (11/30) from nurse managers. Physician directors and respiratory therapist managers agreed to collaborate significantly in most of the key decisions with limited nurses’ involvement (P<0.01). We also found that physician directors were perceived to have greater autonomy and influence in ventilation and waning decision-making with a mean of 8.29 (SD±1.49), and 8.50 (SD±1.40), respectively. Conclusion: The key decision-making was implemented mainly by physicians and respiratory therapists in collaboration. Nurses had limited involvement. Physician directors perceived higher autonomy and influence in ventilatory and weaning decision-making than respiratory therapist managers and nurse managers. A critical care unit’s capacity to deliver effective and safe patient care may be improved by increasing nurses’ participation and acknowledging the role of respiratory therapists in clinical decision-making regarding mechanical ventilation and weaning

Enhanced magnetic properties in ZnCoAlO caused by exchangecoupling to Co nanoparticles

We report the results of a sequence of magnetisation and magneto-optical studies on laser ablated thin films of ZnCoAlO and ZnCoO that contain a small amount of metallic cobalt. The results are compared to those expected when all the magnetization is due to isolated metallic clusters of cobalt and with an oxide sample that is almost free from metallic inclusions. Using a variety of direct magnetic measurements and also magnetic circular dichroism we find that there is ferromagnetism within both the oxide and the metallic inclusions, and furthermore that these magnetic components are exchange-coupled when aluminium is included. This enhances both the coercive field and the remanence. Hence the presence of a controlled quantity of metallic nanoparticles in ZnAlO can improve the magnetic response of the oxide, thus giving great advantages for applications in spintronics

Genetic and phenotypic characterization of NKX6‐2‐related spastic ataxia and hypomyelination

Background and purpose Hypomyelinating leukodystrophies are a heterogeneous group of genetic disorders with a wide spectrum of phenotypes and a high rate of genetically unsolved cases. Bi‐allelic mutations in NKX6‐2 were recently linked to spastic ataxia 8 with hypomyelinating leukodystrophy. Methods Using a combination of homozygosity mapping, exome sequencing, and detailed clinical and neuroimaging assessment a series of new NKX6‐2 mutations in a multicentre setting is described. Then, all reported NKX6‐2 mutations and those identified in this study were combined and an in‐depth analysis of NKX6‐2‐related disease spectrum was provided. Results Eleven new cases from eight families of different ethnic backgrounds carrying compound heterozygous and homozygous pathogenic variants in NKX6‐2 were identified, evidencing a high NKX6‐2 mutation burden in the hypomyelinating leukodystrophy disease spectrum. Our data reveal a phenotype spectrum with neonatal onset, global psychomotor delay and worse prognosis at the severe end and a childhood onset with mainly motor phenotype at the milder end. The phenotypic and neuroimaging expression in NKX6‐2 is described and it is shown that phenotypes with epilepsy in the absence of overt hypomyelination and diffuse hypomyelination without seizures can occur. Conclusions NKX6‐2 mutations should be considered in patients with autosomal recessive, very early onset of nystagmus, cerebellar ataxia with hypotonia that rapidly progresses to spasticity, particularly when associated with neuroimaging signs of hypomyelination. Therefore, it is recommended that NXK6‐2 should be included in hypomyelinating leukodystrophy and spastic ataxia diagnostic panels
