In automotive repair facilities worldwide, technicians are exposed to various ergonomic risk factors such as excessive exertions, awkward and static postures. The exposure of several ergonomic risk factors can lead to work related musculoskeletal complaints. This study was set out to examine working postures encountered by automotive service technicians in a small medium industry automotive workshop. A total of 240 observations (n=240) were made, and five types of working positions were identified, namely the “Underneath Vehicle” (vehicle on floor),“Side of Vehicle” (vehicle on floor), “Under the Hood”, “Side of Vehicle” (vehicle on lift), and “Underneath Vehicle” (vehicle on lift). Two positions, which were the “Underneath Vehicle” (vehicle on floor), and the “Side of Vehicle” (vehicle on floor) recorded 69 and 60 occurrences respectively. These two positions posed a significant ergonomic injury risk since the upper limbs, shoulders, spinal flexion combined with static holding were present in those two positions.

Metro systems have become high-risk entities due to the increased frequency and severity of urban flooding. Therefore, understanding the flood risk of metro systems is a prerequisite for mega-cities’ flood protection and risk management. This study proposes a method for accurately assessing the flood risk of metro systems based on an improved trapezoidal fuzzy analytic hierarchy process (AHP). We applied this method to assess the flood risk of 14 lines and 268 stations of the Guangzhou Metro. The risk results validation showed that the accuracy of the improved trapezoidal fuzzy AHP (90% match) outperformed the traditional trapezoidal AHP (70% match). The distribution of different flood risk levels in Guangzhou metro lines exhibited a polarization signature. About 69% (155 km2) of very high and high risk zones were concentrated in central urban areas (Yuexiu, Liwan, Tianhe, and Haizhu); the three metro lines with the highest overall risk level were lines 3, 6, and 5; and the metro stations at very high risk were mainly located on metro lines 6, 3, 5, 1, and 2. Based on fieldwork, we suggest raising exits, installing watertight doors, and using early warning strategies to resist metro floods. This study can provide scientific data for decision-makers to reasonably allocate flood prevention resources, which is significant in reducing flood losses and promoting Guangzhou’s sustainable development.

Effective Design

Eliminating awkward and stressful working postures through the ergonomics workplace design is important in preventing work-related musculoskeletal disorders. However, effective design tools are currently lacking. Different postural analysis tools have been proposed to help evaluate workplaces in the level of postural stresses experienced by the workers, but they are not capable of supporting the proactive ergonomics in design. In an effort to address the problem, this study presents a novel memory-based workplace evaluation (MBWE) model. When given an input scenario expressed in terms of the worker anthropometric characteristics, the task requirement, and the geometric descriptions of the to-be-evaluated workplace design, the model computes the range of feasible working postures for the scenario, determines their postural stress levels, and presents a report on the overall postural risk level of the input scenario. The MBWE model combines the memory-based posture planning (MBPP) model and the Ovako working posture analysis (OWAS) method.

The Relationship

BACKGROUND: The number of studies investigating the relationship between office employees and the development of musculoskeletal disorders (MSDs) is limited. Only a few focused on assessing workplace ergonomics of office employees. OBJECTIVE: This study aims to investigate the risk of MSDs and associated factors in the office workplaces of a large-size manufacturing company. METHODS: Data were gathered from 208 office employees from a manufacturing company via Rapid Office Strain Assessment (ROSA) and Cornell questionnaire. The collected data were analyzed to examine the relationship between ergonomic risk levels and MSDs reported by the office staff. RESULTS: The mean ROSA final score is 3.52 (std. dev. = 0.71), chair section is 3.30, monitor and telephone section is 2.18, and mouse and keyboard section is 2.69. Thirty-nine of 208 (18.8%) office workplaces are at risk. The most important factor to raise the risk level is found to be the height and depth of the chair. The Cornell questionnaire results highlight that the highest discomfort severity is related to the neck (32.26%), lower back (23.23%) and upper back (22.26%). The discomforts in the neck (r = 0.362), upper back (r = 0.404) and lower back (r = 0.368) are moderately and positively correlated according to the final ROSA score. The results indicate that the highest risked departments are Accounting, Sub Industry, Production Planning, and Manufacturing Management. CONCLUSION: The parameters associated with the chair section should be considered a priority for reducing and eliminating MSDs among office employees.

Introduction: Every worker is exposed to the risk of occupational accidents or occupational diseases when working. Awkward working postures are the postures that cause body parts to detach from its natural postures that can result in the complaints of musculoskeletal disorders (MSDs). This research intends to analyze the factors related to the complaints of MSDs suffered by the shelving staff in the library and reading room in Universitas Airlangga Surabaya. Methods: This research is observational research that applies a cross-sectional design. The sample of this research consists of 27 people chosen by the total population method. The data regarding the individual characteristics and the complaints of MSDs are obtained through interview and filling out a questionnaire that has been standardized. The data on working postures are analyzed by referring to the Rapid Entire Body Assessment (REBA) method, while the data on the complaints of MSDs are scrutinized by implementing the Nordic Body Map (NBM) method. Results: Reveal that most of the shelving staff experience very high-risk level of MSDs (40.7%). Other than that, it is noticed that the working postures consist of squatting (high-risk level), bowing (high-risk level), standing (moderate-risk level), standing with arms stretching (very high-risk level), and standing with arms stretching while tiptoeing (very high-risk level). The collected data is analyzed by using the Spearman correlation test. Conclusion: It can be stated that the strongest factor causing the occurrence of MSDs is the years of service (r=0.803) with a positive relationship, which means that the longer the years of service is, the higher the risk to experience MSDs is. Keywords: complaints of musculoskeletal disorders, individual factors, shelving staff
