Summary: This survey focuses on optimization-based biomechanical lifting models for manual material handling (MMH). Various models, including two-dimensional and three-dimensional models as well as skeletal and musculoskeletal models, are examined. Different optimization algorithms are utilized to solve the lifting optimization problem, and their applications to digital human modeling, back injury prevention, and ergonomic safety design are summarized.

Summary: The study demonstrates that visual MMH instructions with individual real-time feedback can significantly improve lifting technique and reduce factors contributing to lower back pain. Integrating this approach into MMH training programs or on-the-job training can effectively mitigate or prevent lower back pain.

Summary: This study focused on the joint contribution and ground reaction force during team lifting activity. Workplace variables such as weight, height, and gender were found to affect the kinetics and kinematics variables. The results showed significant interactions between gender and load on joint angle and joint moment, as well as the influence of lifting height, stage, gender, and weight on ground reaction force.

Summary: This study aimed to analyze the lower limb EMG muscle activation patterns of healthy caregiver students during lifting tasks. The main findings include a more consistent mean activity of the quadriceps and hamstring muscles as load increases, and intra- as well as interindividual similarity in EMG muscle activation patterns.

Summary: Incremental sheet forming is a versatile method for manufacturing complex parts using computer numerical control, without the need for specialized tools. It is commonly used for rapid prototyping and small batch production, and factors like tool diameter, sheet thickness, step size, and feed rate have significant impacts on product quality.

Summary: This study compared the effects of an ergonomically designed schoolbag and a commercial schoolbag on students' spine and body posture. The results showed that the ergonomically designed schoolbag reduced spinal stress and discomfort, while the commercial schoolbag increased heart rate and discomfort. Therefore, strategies such as new educational inventions and policy changes should be introduced to reduce the potential impact of carrying heavy loads on students.

Summary: This study assessed the physical factors of precision lifting tasks and their effects on muscular activities, heart rate, and perceived exertion. The results showed that wearing heavy safety shoes increased efforts in specific muscular activities and that higher lifting frequency led to rapid increases in heart rate and perceived exertion.

Summary: Laser cutting technology has become increasingly popular in leather cutting due to its advantages such as adaptability, mass production, and reduction in waste. This study investigated the cutting of vegetable chrome-tanned buffalo leather using a 20W laser diode with different control methods. Quality indicators such as emission rate, kerf width, carbonization, and material removal rate were evaluated. The results showed that the pulse width control approach achieved better cutting quality, with higher emission and material removal rates, smaller kerf width, and less carbonization. Optimal cutting parameters were determined using the MOORA approach.
