Authors: Ravhudzulo Hangwani Raymond , Eresia-Eke Chukuakadibia 
Published: July 2024

Objective: To investigate the moderating effect of telecommuting on the relationship between employee engagement, its physical, cognitive, and emotional dimensions, and employee performance within the South African Information and Communication Technology (ICT) sector.

Theoretical Framework: This study adopted the Employee Engagement theory and Social Exchange Theory which provide a basis for understanding the variables under study.

Method: A quantitative research design was adopted. An online survey was utilised to collect data. A combination of non-probability sampling methods was employed to gather a total of 478 complete responses from employees in the South African ICT sector. The data was analyzed using a range of statistical tools, including structural equation modelling, to derive empirical insights and test the proposed hypotheses.

Results and Discussion: The results reveal that telecommuting moderates the relationship between cognitive engagement and employee performance, as well as the relationsip between emotional engagement and employee performance. However, telecommuting did not moderate the relationship between physical engagement and performance, nor the relationship between employee engagement and performance. These findings suggest that telecommuting enhances employee performance primarily through its impact on cognitive engagement and emotional engagement.

Research Implications: The study's findings imply that organizations, particularly in developing economies, should tailor their remote work policies to strengthen cognitive and emotional engagement among employees to optimize performance outcomes.

Originality/Value: This study contributes to the existing literature by providing empirical evidence on the moderating role of telecommuting in the relationship between different dimensions of employee engagement and performance within the ICT sector in South Africa.

Published: July 2024

Constantinople is the city that the Noble Messenger may God’s prayers and peace is upon him, announced his conquest by saying: “To conquer Constantinople, let us be the emir, its ruler, and the best army, that army. And the poets pay attention to it and write about it, as if this city was created to be a great empire that lasted for more than a thousand years. What helped it to survive is its huge building built by Emperor Constantine the Great in 324 AD to be the capital of the Eastern Byzantine Empire. This huge building is represented in its high fortified walls and its huge and remnant churches Now like the Hagia Sophia Church, and making it one of the most important cultural centers and a symbol of ancient civilization in addition to choosing this important geographical location, which gave it a very important economic and commercial importance, helped it to survive and continue and most of the attempts directed against it.
Constantine's great goal was to build it, to continue the survival of the European Empire (New Rome), but this time in the East with a new look and a new religion, which is Christianity by adopting the official religion of the new empire.

This paper aims to address the critical issue of multivehicle truck crashes in developing regions, with a focus on Thailand, by analyzing the factors that influence injury severity and comparing the effectiveness of predictive models. Utilizing advanced random parameters and the XGBoost machine learning algorithm, we conducted a comprehensive analysis of injury severity factors in multivehicle truck-involved accidents, contrasting weekdays and weekends. Our findings reveal that the XGBoost model significantly outperforms the heterogeneous logit model in predicting crash severity outcomes, demonstrating superior accuracy, sensitivity, specificity, precision, F1 score, and area under the curve (AUC) in both model training and testing phases. Key risk factors identified include motorcycle involvement, head-on collisions, and crashes occurring during late night/early morning hours, with environmental elements like road lane numbers and weekend hours also playing a significant role. The study introduces XGBoost as a novel and improved method for truck safety analysis, capable of capturing the complex interactions within multivehicle crash data and offering actionable insights for targeted interventions to reduce crash severity. By highlighting specific risk factors and the effectiveness of XGBoost, this research contributes to the development of data-driven strategies for enhancing truck safety in developing countries.

Assessing Liquefaction Potential in Alluvial Plains Through Spatiotemporal Analysis Using Liquefaction Probability Index
Authors: Berkat Badr , Akhssas Ahmed , Elfilali Omar 
Published: July 2024

Liquefaction is one of the most important processes in soil dynamics. It is a loss of strength coupled with a rapid increase in pore pressure, causing soil particles to burst for a short period. Several approaches have been developed to calculate the residual or liquefied shear strength of cohesionless soils. Using the liquefaction probability index (LPI) created by Juang et al. (2003), the primary goal of this publication is to map spatiotemporal variations in the liquefaction potential of deposits in the Oued Drader and Marja Zerga alluvial plains of the mio-plio-quaternary Gharb basin. The cone penetration test (CPT) and semi-empirical techniques developed to measure the risk of liquefaction and create a mapping of liquefiable zones on a national scale for the first time are the primary sources of information used in the computation of the liquefaction potential index (LPI), which will be highly applicable and relevant for upcoming research projects. According to the IPL calculation, liquefaction is expected to be confirmed for the sandy and silty-sandy formations in Oued Drader and Marja Zerga. The spatial-temporal variations will depend on the formation's granulometry, saturation level, and liquidity limit. The lateral and spatial variety of the Marja Zerga and Oued Drader plain deposits is reflected in this architecture of liquefaction variation. Doi: 10.28991/CEJ-2024-010-06-018 Full Text: PDF
Enhancing the Flexural Capacity of Reinforced Concrete Beam by Using Modified Shear Reinforcement
Authors: Bello Bonjoebee R. , Dela Cruz Orlean G. , Muhi Manuel M. , Guades Ernesto J. 
Published: July 2024

Many researchers have studied how modifying conventional shear reinforcement into spiral and truss systems improves the behavior of RC beams. However, there is a scarcity of studies investigating the influence of spiral reinforcement, and limited research is available on the flexural capacity of beams utilizing truss reinforcement systems. Additionally, recent designs focused only on the rectangular spiral and rectangular truss systems, underscoring the necessity of incorporating a new design of modifications in the stirrup configurations. These gaps must be addressed to identify the most effective design for achieving the desired flexural capacities. As a result, the present study conducts a simulation and experimentation on RC beams utilizing modified stirrups through the Abaqus software to describe the load-deflection relationship, determine the flexural capacity and ductility, and analyze the failure mode and crack patterns. The present study simulated seventeen finite element models, including one control beam as BN and four various designs that used rectangular spiral (BR-S), rectangular truss system (BT-R), and a new modification, namely vertical X-shaped stirrups (BV-X), and X-shaped truss system (BT-X) with four spacings of 150mm, 125mm, 100mm, and 75mm. The findings reveal that the most effective enhancement in RC beam behavior was observed within the BT-R group, particularly with BT-R 100, which demonstrated a remarkable 6.551% increase in flexural capacity compared to BN. Moreover, stirrup spacing and inclination considerably impact the beam's performance, depending on the various modifications of stirrups in RC beams. Furthermore, uniform failure modes have been observed across all models and specimens, including BN, demonstrating that modified stirrups improve RC beam performance. The present study compared and verified the finite element simulation results through an actual experiment from BN and BT-R 150 models and specimens. Doi: 10.28991/CEJ-2024-010-06-02 Full Text: PDF
Comparison of Thermophysical Properties of PIM Feedstocks with Polyoxymethylene and Wax-Polyolefin Binders
Authors: Muranov Alexander N. , Kocharov Maxim A. , Mikhailov Maxim S. 
Published: July 2024

One of the high-performance technologies for the serial production of small-sized metal and ceramic complex-profile parts is powder injection molding (PIM). The most industrially demanded types of polymer binder in PIM technology are polyoxymethylene-based compositions and wax-polyolefin mixtures. Despite the large number of studies devoted to different compositions of polymer binder for PIM technology, the actual task is still a comparative analysis of the properties of different binder types to determine their advantages and disadvantages, as well as the optimization of the used compositions. In this regard, this study aims at a comparative analysis of the thermophysical properties of the most demanded feedstocks with binder based on polyoxymethylene and wax-polyolefin mixtures under the condition of using identical steel powder filler. The specific heat capacity, temperatures, and heat of phase transitions, as well as the thermal inertia and effective thermal conductivity of the compared types of feedstocks, were determined as a result of the calculation-experimental study. The obtained data can replenish the knowledge bases necessary for simulation modeling and optimizing powder molding processes of various products made of 42CrMo4 steel. As a result of a comparative analysis of the thermophysical properties of feedstocks with identical powders, the kinetic effects in the thermal processes of forming feedstocks with polyoxymethylene are less significant than those in analogs with wax-polyolefin binder, which facilitates their moldability. Thus, the feedstock with polyoxymethylene has a significantly higher rate of temperature field leveling than the analogs with wax-polyolefin binder. Because of the insignificant difference in specific heat capacity, feedstocks based on polyoxymethylene have 1.5 times higher effective thermal conductivity and approximately 20% higher thermal inertia than feedstocks with identical powder filler and binder in the form of a wax-polyolefin mixture. The technological advantages of feedstocks with a wax-polyolefin binder include the possibility of processing at lower temperatures. Doi: 10.28991/CEJ-2024-010-06-05 Full Text: PDF
Spatial and Temporal Analysis of Surface Water Pollution Indices Using Statistical Methods
Authors: Kieu Le Diem , Quoc Pham Nguyen 
Published: July 2024

This study was conducted to evaluate surface water quality using pollution indices including the organic pollution index (OPI), comprehensive pollution index (CPI), and water quality index (WQI), cluster analysis (CA), with the support of one-way analysis of variance (One-way ANOVA), and principal component analysis (PCA). Water quality data at 42 locations, with 22 water quality parameters including temperature, pH, turbidity, salinity, chloride, total dissolved solids, electrical conductivity, sulfate, dissolved oxygen, total suspended solids, biological oxygen demand, chemical oxygen demand, nitrite, nitrate, ammonium, orthophosphate, coliform, E. coli, arsenic, cadmium, lead, and copper, were used for the evaluation. The results showed that all the pollution indices fluctuated spatially and temporally. The OPI index ranged from slight organic pollution to heavy organic pollution, and the OPI values in February and April were higher than those in other months. OPI values were classified as moderate with 54.76% of the locations and heavily polluted with 45.24%. Assessment based on the CPI revealed that 16.7% and 83.3% of locations were classified as moderately contaminated and heavily contaminated, respectively. The WQI classified 45% of the locations as poor and 55% of the locations as having average water quality. In particular, the water quality in August, October, and December was better than that in other months. PCA results showed that eight polluting sources were responsible for 77.1% of the water quality variation. The main surface water polluting sources could be natural sources (riverbank erosion, rainwater runoff), wastewater (domestic, agricultural, and industrial), water discharge from the national park, and livestock areas. Local environmental management agencies need to have appropriate solutions to improve water quality. Future research should focus on the contribution sources to surface water degradation.

Hyperemesis gravidarum is the main cause of death, currently the hyperemesis gravidarum is no longer the main cause of maternal mortality, however the hyperemesis gravidarum is still the main cause of maternal mordibility. The cause of hyperemesis gravidarum is not yet known with certainty, with an incidence of 2/1000 pregnancies. Several influences have factors, including predisposing factors (primigravida, hydatidiform mole, and multiple pregnancy). Organic factors (allergies, entry of chorial villi in the circulation, metabolic changes due to pregnancy, and the maternal resistance is decreased). Psychological factors (age, household, job loss, fear). The method used through five stages, namely identifying scoping review questions with the PEOT framework (Population, Exposure, Outcome, and Thema), identifying articles using relevant databases (PubMed, Ebsco, Wiley, Science Direct) and gray literature (Google Scholar). by using keywords, article selection, data charting, compiling, summarizing and reporting results.
