The investigation was conducted by surveying 374 doctors, nurses, and other medical staffs within 19 cities/provinces in the south of Vietnam. The SmartPLS software was used to conduct the partial least squared structural equation modeling (PLS-SEM) technique. The findings from the PLS-SEM analysis reveal that empowerment leadership has a direct positive influence on the employee loyalty to the organization of medical staff as well as a positive impact on intermediate variables such as employee trust and employee job satisfaction. On the other hand, the intermediate variables employee trust and employee job satisfaction also have a positive impact on the employee loyalty toward the organization. This research not only contributes to the existing body of knowledge by evaluating the relationship between employee trust, empowerment leadership, job satisfaction, and employee loyalty but also offers valuable recommendations for the management board of private healthcare organizations in southern Vietnam.</p> 2023-10-25T00:00:00+02:00 Copyright (c) 1970 Hien Pham Implementation of ergonomics and lean manufacturing principles to improve work environment and performance of soccer ball production line 2023-09-04T16:00:00+02:00 Fahad Hussain Muhammad Uzair Muhammad Awais Islam Muhammad Shafiq <p>Value addition and performance improvement are important to deal with increasing local and global market competitiveness. Interventions and automation based on Lean and ergonomics principles have strong influence on performance improvement of the production systems. This study focuses on implementation of lean manufacturing and ergonomics principles to improve work environment and performance of the soccer manufacturing production line. Work visualization and value stream mapping (VSM) techniques were employed to identify the opportunities for improvements. Time of value and non-value-added activities is recorded using time study method. Working postures and associated risk factors are evaluated using Rapid Entire Body Assessment (REBA) method. Lean manufacturing principles are employed to minimize wastes and non-value added activities. Similarly, improvements in work environment are made through ergonomics interventions. Various models comprising different levels of lean and ergonomics interventions were evaluated through simulation before actual implementation. The results of the finalized model in terms of decrease in cycle time (8.64 to 7.018 seconds), increase in daily production (20505 to 24176 soccer balls), and improved work environment are evident of performance improvements in all aspects. The integration of lean and ergonomics principles leads to improve the productivity and working environment for workers in soccer ball manufacturing industry.</p> 2023-11-13T00:00:00+01:00 Copyright (c) 2023 Muhammad Shafiq Development of dough kneading machine for small and medium-sized enterprises 2023-09-04T15:56:35+02:00 Oluwaseun Ojo Anthony Oyerinde Olufemi Sylvester Bamisaye Joseph Adewole Temitope Adepoju <p>This work focuses on the development of a motor-powered dough-kneading machine for small to medium-scale businesses to aid the efficient production of their edible products. It employs dual electric motors configured to rotate in opposite directions on the same axis for an efficient kneading process. The work was carried out at the Department of Mechanical Engineering, Adeleke University, Ede, Osun State. The machine employs upper and lower electric motors configured to rotate in opposite directions on the same axis for an efficient kneading process. The design analysis was carried out in line with the defined specifications, which was followed by fabrication and evaluation. The result showed a kneading torque of 128 Nm at average kneading power and speed of 1.37 kW and 102.02 RPM respectively. The dough volume per batch and the mixing bowl volume were 0.00397 and 0.00512 m<sup>3</sup>. The capacity and efficiency of the machine were estimated to be 0.87 kg/min and 90.65% at the R<sup>2</sup> of 92.2%. The performance showed that the dough-kneading machine is efficient and can be produced in mass to meet the market demands of small and medium-scale businesses.</p> 2023-12-16T00:00:00+01:00 Copyright (c) 2023 Oluwaseun Ojo, Anthony Oyerinde, Olufemi Sylvester Bamisaye, Joseph Adewole, Temitope Adepoju Simulation-based post-fault analysis in WECS using DFIG systems under an unbalanced fault scenario 2023-07-24T14:49:53+02:00 Muzamil Hussain Wadho Surat Khan Sadqain Hassan Muhammad Ahmed Kalwar <p>Fault analysis in an integrated Wind Energy Conversion System (WECS) is the highest priority factor to be taken into account for distributed generation (DG). The contribution of renewable energies (like solar and wind) to the power system is increasing continuously. New challenges are being faced while integrating such systems because of the no inertial response provided by renewable resources. So, for a reliable integration further exploration, development, and even new strategies are needed to improve the reliability, power quality, control and protection of renewable energy generation. Disintegration in distributed generation is still a huge question mark on the reliability of modern power systems. Disintegration has many causes and faults are one of them, that cause severe voltage profile distortions, which makes WECS a complex system in terms of control and protection of power system. In this work, focus has been paid to the analysis of asymmetrical faults in wind farms and their impacts are evaluated on the overall generation system. A 30 MW wind power plant has been developed in MATLAB to study the faults. Since wind farms are Low Voltage (LV) networks, therefore, fault impedance method (IEC 60909) and the Fort-cue Method have been used for the fault analysis. The fault current response and behaviour of the DG system under asymmetrical fault conditions at different locations in and around the wind farm have been obtained. It is found that fault loop impendence, transformer grounding type, and fault location largely affect the dynamic behaviour of the co-generation system under asymmetrical faults. In this work dynamic behaviour of the wind generation system has been analysed for the different asymmetrical faults induced at different locations of the system. The response of the wind generator has been evaluated based on the different fault simulations considering the sequence component method.</p> 2023-12-18T00:00:00+01:00 Copyright (c) 2023 Muhammad Ahmed Kalwar
