Authors: Maheshwari Anubha , Pandey Gayatri , Shukla Manish , Rawat Vijay Singh , Yadav Tanushree 
Published: June 2022

Research purpose. This study aimed to determine the EMG analysis of forehand topspin using different ball materials.
Materials and methods. For the purposes of this study, seven male university-level table tennis players who were right-hand dominant players (age 21.1 ± 2.4 years, height 162.6 ± 6.8 cm, mass 61.8 ± 3.2 kg) with at least 6 years of playing experience were selected. The selected participants were physically active and had no physical injuries. The study was approved by the research committee. Pectoralis Major (PM), Deltoid Anterior (DA), Latissimus Dorsi (LD), Biceps Brachii (BB), Extensor Carpi Radialis (ECR), Flexor Carpi Radialis (FCR) muscles were selected for the electromyographical study. One of the EMG signals variable Root Mean Square was measured in all muscles, through which the maximum muscle involvement was evaluated. For each assessed muscle and both ball materials, the mean value of Root Mean Square EMG signals was computed. For descriptive statistics, minimum, maximum, mean, and standard deviation were used, and a t-test was used as a statistical technique.
Results. The level of significance was set at 0.05. Results of the study showed no significant difference in EMG variable Root Mean Square between celluloid and poly plastic ball material on selected muscles.
Conclusions. We conclude that the biceps brachii and extensor carpi radialis are important muscles for the forehand topspin because they are responsible for flexion of the arm and work strongly in the action of gripping in the performance of quick forehand spin strokes.

Background. Today, the problem of doping is the most well-known negative phenomenon in modern sport, which has become widespread in response to its active commercialization. The majority of people would agree that doping issue has moral and ethical basis, therefore the educational component of anti-doping policies is most promising in achieving the desired result – doping-free sport.
Research purpose. The study was aimed to investigate the peculiarities of the ideas sambo athletes may have about the problem of doping in modern sport.
Materials and methods. The study involved 97 highly professional sambo athletes from 21 countries, namely Russia, Ukraine, Mexico, Japan, the USA, Canada, Cuba, Guatemala, Republic of Korea, Colombia, Paraguay, Venezuela, Peru, Brazil, Nicaragua, El Salvador, Dominican Republic, Puerto Rico, Honduras, Uruguay, and Costa Rica.
Results. A survey conducted among the professional sambo athletes, participants of the 2018 World Cup, made it possible to establish their knowledge about and their attitude to doping. It became known that 76.29% of the athletes were well familiar with the doping control procedure, while 23.71% were not. At the same time, 78.35% of the respondents believed that they knew their rights and responsibilities during the doping control procedure, and 21.65% of the athletes did not. 77.32% of the respondents knew the organizer of doping control and 22.68% did not.
Conclusions. The analysis of the study results and WADA statistics give grounds to state that the problem of doping in modern athletes remains an urgent problem in professional sports, including sambo.

Authors: Del Prete Annachiara , Redón Pantoja Silvia 
Published: June 2022

Frente el aumento de casos de ciberviolencia en contra de las mujeres adolescentes, se hace necesario entender y combatir el fenómeno, desde una aproximación crítica a algunos rasgos que diferencian esta violencia de género a otros tipos de violencia contra la mujer y contra la mujer adulta, como consecuencia de las características propias de la fase de la adolescencia, así como de su “normalización” por parte de algunos discursos de las instituciones. A través del análisis de 36 entrevistas etnográficas semiestructuradas, aplicadas a adolescentes pertenecientes a la región de Valparaíso, Chile, se lleva a cabo un análisis de contenido de las experiencias y/o percepción del fenómeno de ciberacoso de género, priorizando una perspectiva interpretativa crítica. Entre los principales hallazgos se destacan la normalización de los fenómenos violentos en la percepción de las y los jóvenes, la invisibilización de actos de ciberviolencia y un aumento de ciberviolencia en las relaciones entre mujeres adolescentes.
Platelet indices as an acute phase reactant in infants admitted with acute febrile illness
Authors: Tariq Syed , Thoker Wasim Yousuf 
Published: June 2022

Background: The most common causes of thrombocytosis are infectious illnesses; platelet count is unaffected by fever duration. Infectious disorders such rotavirus gastroenteritis, respiratory syncytial virus infection, hepatitis B and C virus infection, brucellosis, and pulmonary tuberculosis, and also medical and non-medical situations, might impact mean platelet volume (MPV) readings. C-reactive protein (CRP) plasma concentration changes during infection or inflammation as part of the innate immune response. Aim was to investigate in children with febrile illness the correlation between platelet indices and CRP.Methods: This hospital based descriptive study was conducted in post graduate Department of Paediatrics and Neonatology, an associated hospital of Government Medical College and Hospital, Srinagar, from December 2019 to November 2021. As per sample size calculation 3000 patients were included in the study. Patients of either sex, age from 1 month to 1 year of age with fever admitted in hospital were included in the study.Results: There was a significantly positive correlation between platelet count and CRP. The sensitivity was highest for platelets at 96.67 and lowest for MPV 32.97 while as specificity was highest for white blood cells (WBC) at 94.4 for MPV was 92.22 and lowest for platelet (PLT) 30.77. Spearman rank correlation between platelet indices and CRP value children with fever with high CRP had a significantly high PT and it has significant positive correlation with CRP.Conclusions: We found a strong link between CRP and platelet counts in patients. Platelet count, platelet distribution width (PDW), MPV, and plateletcrit (PCT) were all influenced.

Published: June 2022

<p>COVID-19 pandemic has brought significant and multiple challenges for small and medium enterprises (SMEs). While SMEs have traditionally faced financial and non-financial crises, the pandemic has brought about additional uncertainties on how to maintain business continuity. The purpose of this paper is to examine how SMEs can mitigate against COVID-19-related crisis by examining the impacts that the pandemic has had on them through a review of 34 articles. The thematic analysis from the literature covered three overarching and inter-related challenges including: (i) cost and finance-related challenges, (ii) disruption of activities, and (iii) existential difficulties. This paper highlighted three major crises emerging out of the COVID-19 pandemic for SMEs. Cost-and finance-related challenges, disruption of SME activities amidst COVID-19 pandemic and Digital technologies. The paper’s value lies in addressing the gap between the espoused literature’s claim of the beneficial impact of new technological advancements and SMEs’ ability to survive in the context of the COVID-19 pandemic.</p><p> </p>
Explaining social determinants of health from a political economy of health and ecosocial perspective
Authors: Gunamany Susanna 
Published: June 2022

Social determinants of health (SDH) is a common term used in public health and epidemiology. Public health researchers use social determinants of health to study various inequalities associated with health. Inequities in health involve systematic differences in health across population subgroups, thus changing the focus of influences from social interactions to societal characteristics. Several epidemiologic literatures focus on the social aspects of individuals and groups that are considered to influence the health status, which is conceptualized as 'average health'. Some studies look beyond the social factors affecting health; social determinants of health as arising from a social environment structured by government policies and status hierarchies, with social inequalities in health resulting from diverse groups being differentially exposed to factors that influence health, whereby 'social determinants', such as poverty, act as the 'causes of causes'.<strong> </strong>However, the most recent definitions of SDH include the factors such as political-economic systems, whereby health inequities result from the promotion of the political and economic interests of those with power and privilege and whose wealth and better health are achieved at the expense of those whom they subject to adverse living and working conditions. Hence, social determinants such as political-economic systems that prioritizes the highly concentrated accumulation of private wealth over the redistribution of power, property and privilege within and across countries constitute the 'causes of causes of causes'. In this paper, the concept of social determinants of health will be discussed in more detail, using two different theories of social epidemiology that focus on the SDH: the political economy of health and the ecosocial framework.

Published: June 2022

<p>Pure subtalar dislocation is a rare injury. It accounts for 1% of dislocations seen in trauma. It involves a loss of anatomical relationship between the talus, calcaneus and scaphoid, but the tibio-peroneal-astragalic congruence is maintained. The aim of this study was to find an explanation between the occurrence of subtalar dislocation in its medial variety and the Jakarta motorbike crash. Five male patients who had fallen from a Jakarta motorbike were included. Two cases of open dislocation were reported. They received wound trimming under spinal anaesthesia. We proceeded to reduce the dislocation using a boot puller maneuver and restraint with a plaster boot. The postoperative course was simple with wound healing. The casting lasted 6 weeks but was extended to 8 weeks for open dislocations. After removal of the cast, rehabilitation was prescribed for all patients. This consisted mainly of proprioception in order to restore the functions of the ankle. At a mean follow-up of 25.2 months, the patients did not complain of pain or stiffness and the X-rays taken were normal.</p>

Introduction: Most critical accidents in different industries are observable, but their severity is also predictable and can be controlled. Provided that accident analysis is properly managed with a preventive approach and based on correct findings, in a principled and realistic manner, root causes, corrective actions, and safety measures regarding accidents are performed.
Material and Methods: The present research was a descriptive-analytic study, and the reported and recorded fatal occupational accidents were analyzed in the onshore section of one of the construction refinery projects in the South Pars Gas Refinery over a decade using the Tripod Beta method and then main risk factors, pre-conditions, and underlying causes, as well as the existing protective barriers, were identified, and an accidents tree was drawn.
Results: The analysis of fatal occupational accidents showed that 26 immediate causes, 39 preconditions, and 50 underlying causes were involved in those accidents. Six key risk factors include lack of responsibility/organizational impact (57.8%), training (22.2%), hardware or tools and equipment (6.7%), maintenance management (6.7%), work procedures (4.4%), and Error Enforcing conditions (2.2%) had the largest share of the occurrence of accidents.
Conclusion: More than 80% of fatal occupational accidents can be controlled by modifying the two main factors, responsibility and organization and training. Therefore, implementing the total productive maintenance method, effective monitoring of staff work, hiring staff with sufficient knowledge and skills, and improving training indicators will increase understanding of hazard sources, improve safety and reduce accidents.

Introduction: Today, it is essential to pay attention to the opportunities and threats in health services, especially in hospitals, to identify and evaluate the existing risks and manage them in these centers. Hospital risk management is a program to reduce the occurrence and prevalence of preventable accidents and is of great economic, human and moral importance in the hospital environment. This study aimed to evaluate and prioritize the occupational safety and health risks of the staff of Shahid Sadoughi Hospital in Yazd in 2019
Methods and material: : The present study is descriptive-cross-sectional. In the first step, the main risks in clinical, laboratory, facilities, radiology, and administrative departments were identified. Based on FMEA logic, three severity, probability, and vulnerability indicators were identified for each risk. Then, prioritization criteria were determined, and ANP prioritized the risks.
Results: According to infectious disease experts with a risk of 0.86 in the clinical ward, inhalation of Barisek chemical vapor 1.17 in the laboratory, radiation of the device with a risk of 0.64 in imaging, infectious disease with a risk of 0.33 and 1.3 in order of priority The first were in the administrative and facilities department.
Conclusion: The results showed that the hospital management should adopt special management programs to control infectious diseases with a staff health approach. Control measures should be set with priority risks. The difference in the obtained risk numbers indicated the different priorities of implementing risk management programs in each ward of Shahid Sadoughi Hospital.
Systolic Myocardial Velocity by Tissue Doppler Imaging versus Left Ventricular Ejection Fraction by Simpson’s Method in Yemeni Patients with Heart Failure
Authors: Obeid Faida 
Published: June 2022

Objective: To compare between systolic myocardial velocity (Sm) by tissue Doppler imaging (TDI) and left ventricular ejection fraction (LVEF) by Simpson’s method in Yemeni patients with heart failure (HF).
Method: This study included 85 HF patients whose LVEF was <50.0%. LVEF was measured by Simpson’s method and Sm was measured by TDI at septal, lateral, anterior and inferior sides of the mitral annulus.
Results: The mean age of the patients included in the study was 58.5 ± 11 years. The mean LVEF was 33.53 ± 9.94, while LV mean Sm (cm/s) was 2.67 ± 1.43. A significant correlation was detected between LVEF obtained by Simpson’s method and LV mean Sm obtained by TDI (r = 0.609, P < 0.001).
Conclusions: A significant correlation was found between LVEF and Sm among Yemeni patients with HF. Therefore, Sm obtained by TDI can replace LVEF in the assessment of LV systolic function in Yemeni HF patients. Large-scale, controlled studies are recommended to provide further evidence on the utility of Sm by TDI in assessing the LV systolic function in HF patients in different areas of the country.

An efficient solar water desalination system using natural vacuum pressure
Authors: Al-Muylaba Mohammed , Abdel Dayem A. M. 
Published: June 2022

An innovative design of a solar natural vacuum desalination (SNVD) system is proposed and investigated. To obtain a vacuum pressure in a desalination chamber its height is considered as 9.5 m. The waste heat in the system is efficiently utilized for both brine and distilled water. Seawater is preheated by the produced warm water, then, it is heated again by the outlet rejected hot brine before it is charged into the evaporation chamber. In addition, inlet pure water to a flat-plate collector is preheated by the condensation latent heat of the evaporated vapor from the evaporation chamber. Later, the outlet hot water from the collector is used as a heat source to the evaporation process. An optimum design of the system components was provided under the actual weather conditions for the shortest day of the year. It was found that the collector area is required to be 23 m2 to produce 66.6 liter of distilled water during. A mathematical modeling of the system was provided to establish a transient simulation and investigate the hourly performance of the system. Based on the annual performance of the system, the system can produce 76.5 liter of distilled water daily that is corresponding to 3.5 liter per one quadratic meter of collector. The annual average specific productivity of the system is obtained as 1.44 liter per kWh of solar radiation. Moreover, the maximum annual production is estimated as 92.88 liter of distilled water per day. Accordingly, the evaporation ratio (ER) is dependent on the solar irradiation and the annual average is found 0.0175 (or 1.75 %) where the gain output ratio (GOR) was estimated as 0.97 on yearly average basis.
