Abstract The best time for PAUD teachers to lay the foundation for religious education. Although the role of parents is very important in building religious values for their children, early childhood teachers play an important role in equipping students with a religious foundation. Therefore, PAUD teachers and parents must always work hard in various ways to be able to guide children to grow on the basis of a good personality, which is based on religious values. This research uses literature study, namely data collection or scientific work for research purposes or data collection in the form of literature. The results showed that basic knowledge of religious education could be given to children according to their age. Therefore, parents and educators must be creative in equipping children with religious values in order to stimulate children's interest correctly and correctly.

Published: March 2022

The purpose of the investigation is to study the operating conditions of the downstream of the low-pressure conjugation and water passageway structures of the reclamation complex of the agro-industrial complex (AIC) in relation to the structural scheme of culvert sections operating in the conditions of the conjugation of the pools by the type of a submerged jet in the presence of a deep, relatively short stilling well. A brief description of the laboratory installation, the measuring equipment used to record turbulent fl ow characteristics and the methodology for performing model studies is given. The results are given on fi nding and studying rational downstream structures and devices (hearth, baffl es, apron) taking into account pulsating fl ow effects on the fastening elements. The fl ow modes behind the culvert structure and spillway dam with a deep well have been established, calculated dependences are given to determine its optimal parameters and assess the average and pulsation components of pressure on the main elements of the downstream devices. On the model operating at the Reynolds numbers over 10000 and Froude numbers in the compressed section from 20 to 120, a design was chosen that provides the greatest energy baffl e effect at the angle of the turbulent jet entry into the well varying within 50°…70°, which includes blocks in addition to the deep short well. This made it possible to analyze the kinematic structure of the fl ow and reveal the intense attenuation of the pulsation component of the fl ow velocities and pressures along the length of the outlet channel by about 20% compared to a jump well of simple outlines, and a decrease in the planned irregularity of the diagrams. All this together confi rmed the effi ciency of the structure on the sloping sections of the reclamation network for the structures with a specifi c fl ow rate in the range of 0.15…5.5 m2 /s. As a result of the research carried out, the design of the device and downstream anchorage has been improved providing the necessary reliability of its operation.

Published: March 2022

The article presents the results of the development of three-dimensional modeling and the results of forecasting the pollution of a water body with biogenic elements on the example of the Pekhorka River in the Balashikhinsky district of the Moscow region. To solve the problem of improving the environmental safety of the river basin, a mathematical three-dimensional model for predicting pollution by biogenic elements has been developed. As an assessment of the pollution of the Pekhorka River, the method of assessing the impact on the indicator of chemical pollution was chosen. The development of a mathematical model of pollutant transport was carried out using the Python Version 3.8 programming environment. The mathematical models considered two scenarios of river pollution: actual river pollution with biogenic pollutants and forecast pollution. As a result of modeling, the nature of mixing and longitudinal dispersion along the river fl ow was determined. It was found that vertical mixing occurs quite quickly at a distance of several depths of the river, lateral mixing occurs much slower, but usually ends within a few kilometers downstream. Three-dimensional mathematical models for predicting water body pollution are designed to quantify the dynamic processes of mass transfer in space and time and allow solving problems of environmental safety of catchment areas and water bodies.

The purpose of the study is to assess the possibilities of combining the processes of mixing coagulant and agitating (formation of flocculant), developing, designing and testing the installation that ensures the compatibility of processes and the use of compressed air in the mixing process to achieve standard indicators of drinking water quality at the lowest possible economic costs. The article contains the results of research to assess the possibilities of achieving the quality indicators of drinking water from surface sources of the Syrian Arab Republic in conditions of regulated runoff. The experiments used water from reservoir 16 Tishrin, as a coagulant aqueous aluminum sulfate [Al2 (SO4)3. 18H2O], water samples for experiments were stored until a temperature close to ambient temperature was reached. A combination of a flocculation chamber and a mixer for a water purification plant is proposed, as well as a method for using compressed air as a mixing factor instead of mechanical mixers. Before the start of the experiment, measurements of the temperature and pH of the water were carried out, as well as the calculation of the amount of air required to perform the processes of mixing and the formation of a flocculant. Due to the combination of the mixer and the flocculation chamber, the possibility of increasing the efficiency of water purification and reducing operating costs when using compressed air for mixing has been established; it has also been possible to determine the optimal values of the parameters of mixing and mixing processes used in water treatment; to improve mixing efficiency and water purifi cation quality; to reduce operating costs for water treatment; to optimize the layout of individual elements of the water treatment system.
A Statistical Model to Predict the Strength Development of Geopolymer Concrete Based on SiO2/Al2O3 Ratio Variation
Authors: Ali Ali A. , Al-Attar Tareq S. , Abbas Waleed A.
Published: March 2022

Geopolymer Concrete (GPC) is a new class of concrete that presents a vital improvement in sustainability and the environment, particularly in recycling and alternative construction methods. Geopolymers offer a sustainable, low energy consumption, low carbon footprint, and a 100% substitute for the Portland cement binder for civil infrastructure applications. Furthermore, many aluminosilicate materials can be obtained as by-products of other processes, such as coal combustion or the thermal pulping of wood. In addition, slag and fly ash are necessary to source materials for geopolymer. Therefore, geopolymer is considered a solution for waste management that can minimize greenhouse gas emissions. In this statistical study, the present experimental work and found experimental data were collected from local and international literature and were used to build and validate the statistical models to predict the strength development of Geopolymer concrete with binary and ternary systems of source materials. The main independent variable was R, representing the ratio of SiO2/Al2O3by weight in the source material. The investigated range of R was 1.42–3.6. Nine concrete geopolymer mixes with R in the above range represent the experimental part carried out. The targeted properties were compressive, splitting, and flexural strengths. The experimental results showed that the R ratio significantly influences the mechanical performance of the final product. The compressive strength improved by 82, 86, 93, and 95%, when metakaolin content was partially replaced by fly ash and GGBS by percentages of 30, 70, 72, 90, and 95% for mixes 2, 3, 5, 7, and 8 respectively. Also, when GGBS partially replaced fly ash content by 36% and 100% for mixes 6 and 9, compressive strength improved by 10.6% and 41.8%, respectively, compared to mix4. Furthermore, the statistical study revealed that the R ratio might be utilized to determine geopolymer strength with reasonable accuracy. The built models were developed by linear and non-linear regression analysis using SPSS software, version 25. Doi: 10.28991/CEJ-2022-08-03-04 Full Text: PDF

Se presenta una adaptación del Cuestionario de Síntomas de Fatiga Laboral de Yoshitake (1978) -versión castellana de Barrientos, Martínez y Mén-dez (2004)- respecto de su formato de respuestas con el fin de hacerlo más susceptible de manejar al momento de analizarlo a la par de otras escalas. Los participantes fueron voluntarios que al momen-to de la entrevista estuvieran trabajando en una organización. Los cambios del cuestionario fueron respecto del formato de respuestas (de ser dicotó-mico se convirtió a politómico). Los resultados muestran un ajuste de la escala a la estructura facto-rial propuesta desde la teoría. Se eliminaron siete ítems, quedando veintitrés repartidos en tres subes-calas. Al primer factor se le denominó síntomas generales de fatiga laboral (9 ítems), el segundo fue denotado como fatiga física (7 ítems) y el tercero como componentes psicológicos de la fatiga (7 ítems). En términos de consistencia interna el ins-trumento presentó niveles adecuados de alfa de Crombach. Se concluye resaltando la necesidad de comprobar la adecuación de esta escala, lo que se conseguirá a través de estudios empíricos.
Remote physiology practical: Viable alternative to in-person practical in health sciences education?
Authors: Tan Charmaine , Low Ivan Cherh Chiet
Published: March 2022

Introduction: Practicals are core components of an undergraduate health sciences curriculum to promote experiential learning and motivation in students. With restrictions on traditional forms of face-to-face practicals during the COVID-19 pandemic, we designed and investigated the efficacy of remote practicals as a viable learning strategy in exercise physiology teaching.
Methods: Student volunteers were instructed to perform a graded exercise test in a remote setting and provide their collected data for subsequent discussion in an online lecture. The effectiveness of this remote practical in promoting students’ motivation and learning outcomes achievement was assessed via an anonymous questionnaire containing 29 closed-ended and 2 open-ended items. Continual Assessment (CA) results were also investigated. Unpaired student’s t-tests were performed for comparisons between interventions with significance level set at P<0.05.
Results: Sixty-one (out of 81; 75%) students responded to the questionnaires and 49 (60%) consented to the use of their CA results for this study. Results revealed that students were moderately motivated and attained strong achievement of learning outcomes. When compared to students who did not volunteer for the hands-on component of the remote practical, students who participated in the hands-on component reported significantly higher self-efficacy (P<0.05) in explaining the practical procedures to their peers. Qualitative analysis further revealed that experiential learning and real-life data analysis were the central reasons supporting the effectiveness of the remote practical. Students were generally satisfied and would recommend the remote practical to future students.
Conclusion: Our study highlights the potential of remote practicals as viable alternatives to traditional practicals.

Published: March 2022

Introduction: Magnetic Resonance (MR) safety is critically important in any Radiology Department, and MR-related accidents are preventable. Serious games provide opportunities for learners to build MR safety awareness through play in an immersive learning environment by using simulated scenarios such as screening virtual patients and managing an MR-related accident.
Methods: We developed a serious game, in partnership with a game developer, introducing MR safety concepts to learners as they navigate through a virtual 3D Radiology department. Drag-and-drop minigames are incorporated to aid the learner to identify hazards in and around the MR environment. Virtual patients are placed in waiting areas to provide realism, and learners are tasked to screen them as part of MR Safety Screening checks. A simulation of an MR-related accident prompts learners to make decisions or take actions to ensure safety and mitigate further risks during the accident. The learner also role-plays as a Risk Officer to identify the multiple key incidents that led to the accident. These formative assessments, with instantaneous feedback, assesses the learners' knowledge of MR safety.
Results: Pilot feedback of this serious game revealed that it is realistic, engaging and relatable. The instructions within the game were clear and aided learning. The game has also been scaled up and customised for the radiology departments of 3 other healthcare institutions.
Conclusion: Serious games provide a training solution to raise MR safety awareness by simulating real-life scenarios in an immersive learning environment. It supplements face-to-face training and is scalable to other healthcare institutions.

The Effects of Cutting Parameters Used in Milling X153CrMoV12 Cold Work Tool Steel by End Mills on Surface Roughness and Hardness of The Workpiece
Authors: CERİTBİNMEZ Ferhat , KANCA Erdoğan
Published: March 2022

The aim of this work is to investigate the effect of the spindle speed and feed rate used in milling X153CrMoV12 cold work steel by X5070 blue coated solid carbide end mill on surface roughness and hardness of the workpiece. For this purpose, 0.2 mm material was removed in one pass without using refrigerant with the machining parameters of 2000, 2500, 2800, 3000 rpm spindle speed and 160, 180, 200, 240 mm/min feed rate. As a result of the tests, the topographic structure, surface roughness, surface hardness and microhardness of the machined surfaces were determined by Leica DMS300, Mitutoyo SJ 210, HRS-150 digital rockwell hardness tester and microhardness tester Future-Tech FM-700, respectively. As the feed rate increased at a constant 2800 rpm spindle speed, the surface roughness increased as the amount of metal removed per unit time increased. Surface roughness decreased at constant 180 mm/min feed rate and high spindle speed values. The effects of spindle speed and feed rate machining parameters on the surface hardness were not much, and the hardness value before and after the process was measured between 60-62 HRC. However, it was determined that the microhardness value decreased due to the use of heat-hardened steel as well as the heat generated by the milling parameters in the regions 50-350 µm deep from the machined surface.

Authors: Rahman A. , Setiyadi Muhammad Wahyu
Published: March 2022

This study aims to determine the mercury accumulation in Gerris sp and its potential as a bioindicator. This type of research is experimental research. This research was conducted at Lake Taliwang and the UGM Integrated Research and Testing Laboratory. The sampling point in this study was determined based on the distance to the pollutant source. It was divided into station 1 (inlet), an area close to the pollutant source, and station 2 (outlet), far from the pollutant source. There are 3 test tests: the accumulation of mercury in water and sediment, mercury in the gerris, and the gerris as a bioindicator of mercury pollution. Analysis of the test results data is presented in descriptive statistics. The results of this study are (1) The waters of Lake Lebo are polluted by mercury, found in sediments and water, and enter the food chain, namely gerris. The mercury concentration in the inlet area is greater than the outlet area because it is closer to the pollutant source (2). Gerris can be used as a bioindicator of mercury pollution in Lake Lebo Taliwang because it can accumulate heavy metals. It meets the criteria of bioindicator organisms and is very strongly correlated with water. The finding suggests that the local government makes regulations regarding mercury metal pollution in Taliwang Lake because mercury metal can enter other food chains and is toxic to living things.

Unmanned aerial vehicles (UAVs) are aircraft that can be controlled remotely or autonomously without a pilot on the platform deck, with the help of Auto-Pilot and software-controlled flight plans. Unmanned aerial vehicles (UAVs) are a component of the Unmanned Aerial System (UAS). For this reason, those who program the mission pattern of these vehicles in advance, use them by remote command with or without sight, how to act in the face of possible developments during the mission, and who know the UAV technology and working principles well in this context, if the connection with the unmanned aerial vehicle (UAV) is lost, The training of the pilots, who enter the necessary information into the system as a command, in order to complete their mission and return safely to the starting point or to a different place, is very important. A professional and qualified UAV pilot/operator should possess five key characteristics, including professional dedication, sense of duty, self-control, enthusiasm for work, logicalness, and rationality. While preparing personality tests for pilot candidates, it should be based on measuring five main personality areas (neuroticism, extraversion, openness, agreeableness and conscientiousness). In the last 20 years in Turkey, the number and kinds of UAVs used especially in the field of security has been constantly increasing, and the number of national and domestic projects is increasing at a level that can compete with their counterparts in the world. Armed unmanned aerial vehicles (Armed UAV) are used extensively in domestic and international security operations, especially in internal security operations, contributing significantly to the success of the operation and reducing casualties and risks. For that reason, this research is focused on UAV pilots education and training as key personnel of UAV and try to bring front important issues of training period.
Infinite Jest’s Voice(s)
Notes for an (Audible) Map
Authors: Ardovino Adriano , Masiero Pia
Published: March 2022

We often refer to a book as having a voice that sounds uniquely distinctive, a voice that stays with us after a book is over. Voice is a key narratological term; together with its twin partner – focalization – it constitutes the skeleton of a given storyworld. The first – experiential – conception of voice is difficult to grasp and articulate and has something to do with a specific tonality we perceive in a direct, almost visceral way. The second – scholarly – produces a host of definitional moves, which tend to crystallize it in a dominant mode of articulating a story. “Infinite Jest’s Voice(s)” aims to bridge the two conceptions of voice just sketched, trying to give the sense of the book’s having a distinctive, unforgettable, voice as far as the reader’s experience is concerned.

Published: March 2022

Objective: to analyze the occurrence of pressure injuries related to medical devices in patients admitted to an intensive care unit. Method: quantitative, observational, descriptive, prospective cohort study, carried out with 171 patients, from May 15 to August 31, 2018 in the intensive care units of a public hospital in the Federal District. Results: the main risk factors were the presence of pressure injuries at admission, with a significant association for the formation of pressure injuries related to medical devices (p=0.002), and patients who progressed to death, with an association for the formation of pressure injuries related to medical devices (p=0.012); medical device-related pressure injury incidence rate of 40.35%. Conclusion: the use of medical devices has grown, as well as the appropriation of these technologies in the critical care environment. The multidisciplinary team should be aware of the formation of pressure injuries related to medical devices that can affect hospitalized patients.

História do Trotskismo no Brasil (1928-1936)
Authors: Prado Carlos
Published: March 2022

The present work takes as its object of investigation the first Brazilian organizations linked to Trotskyism, in the period between 1928 and 1936. The Brazilian Trotskyist movement originated from certain historical conditions, from a rupture caused by national, particular factors, but which were directly related to divergences that shook the Russian Revolution and the international communist movement. The Lenine Communist Group (GCL), founded in May of 1930, was the first Brazilian organization to establish contact with the International Left Opposition. The group had a short life, but gave rise to another organization with the same Trotskyist ties. In January 1931, the Communist League (LC) emerged, which in 1933 adopted the name of the Communist Internationalist League (LCI) and operated until the end of 1936. As for methodological procedures, this research sought to dialogue with historiography, but to advance in the investigation a wide search was carried out in all available documentation. From the consultation and analysis of primary sources, we sought to reconstruct the discourse and political positioning of Trotskyist organizations. Despite the fact that the groups and parties that claimed Trotskyism were in general minority, made up of a few dozen militants and sympathizers, it is necessary, even today, due to their impact on militant culture, the depth and penetration of their criticism and theoretical formulation, investigate and discuss the performance of these organizations. In short, it is a question of recovering a debate that is still very current and necessary

Organizational Commitment Impact on Job Well-Being of SMEs Employees in Taiwan in Post-COVID-19 Era
Authors:   Fu Jen Catholic University, Taiwan, Pan Te-Han , Lin Yao-Nan
Published: March 2022

Taiwan's industrial structure is mainly composed of small and medium-sized enterprises (SMEs), with over 98% of enterprises being SMEs and employing more than 80% of the workforce in Taiwan. Many industries are under severe stress due to the COVID-19 outbreak, and many companies are reducing staff hiring or staff working hours. The main purpose of this study was to examine the factors influencing the job well-being of Taiwanese SME employees in the context of the COVID-19 epidemic, including organizational justice, job insecurity, decent work, and organizational commitment. Through a questionnaire survey, 653 valid questionnaires were collected and analyzed using structural equation modeling to verify the effects between the study constructs. The study found that organizational justice, job insecurity, and decent work all had significant effects on organizational commitment, with job insecurity having the least effect. Organizational commitment has a positive and significant effect on employees' job well-being, with a standardized regression coefficient of 0.469. In the research model, the R2 of employees' organizational justice, job insecurity, decent work, and organizational commitment on job well-being was as high as 0.724. The results of the study show that Taiwan has a large number of SMEs that can respond quickly and flexibly to the environment. Even in the unsettled environment of an epidemic, employees' organizational commitment to the company remains a decisive factor in employee well-being. The smaller-than-expected impact of employee job insecurity is indirect evidence of the resilience of the Taiwanese industry.

The present study aims to examine the mental toughness levels of the coaches in terms of some variables who participated in the third (3rd) level athletics coaching course opened by the Turkish Athletics Federation at different times in 2021. The population of the research is 156 coaches who participated in athletics coaching courses, and a total of 141 of them are 85 men and 56 women (Age Average= 27.00±5.00). With the personal information questionnaire developed by the researcher, "Sport Mental Toughness Questionnaire-SMTQ-14" which was developed by Sheard et al. (2009) was applied. The skewness-kurtosis normality distribution test was used to determine whether the measurements were suitable for the normal distribution. According to the Skewness-Kurtosis technique, the mental toughness scale showed normal distribution for its total and sub-dimensions. According to the results of the research, it can be said that the total and sub-dimension levels of the participants' mental toughness scale are moderate. While there was no significant difference in terms of age and working time of the participants participating in the research, a statistically significant difference was found in terms of gender, place of residence, doing sport and duration of doing sports.
