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.

This study conducted an ergonomic evaluation of the working posture of workers engaged in various processes in the packaging section of a food manufacturing company. Workers in the packaging section of the food manufacturing company were divided into operating, folding, packing, carton wrapping and palletizing. Forty of the workers in the packaging section were placed under observation through video recording of their daily activities for a period of three months to obtain their working postures. Rapid Upper Limb Assessment (RULA) was used to analyze the working postures in order to obtain their ergonomic risk levels. Computer codes for RULA were written for quick and easy evaluation of upper arm, lower arm, wrist, wrist twist, neck, trunk and leg postures. The results from RULA indicated that 25% of the workers in the operating and folding units were exposed to medium ergonomic risk level; 30% of the workers in the packing unit and 10% of the workers in the carton wrapping unit were exposed to high ergonomic risk level while 10% of the workers in the palletizing unit were exposed to a very high ergonomic risk level. The study concluded that workers in the packaging section of the food manufacturing company were exposed to between medium and very high ergonomic risk levels of working posture necessitating the need to change the conditions of their workstations.

Workers' activities basically have a positive and negative impact, one of which is the result of a disturbed skeletal and muscular system, which is a decrease in the strength level of body parts which constitutes work productivity when carrying out daily activities. Knowing the danger level of body posture carried out by the welding position, so that it can be given useful input for the company's progress. The method used is the Rapid User Limb Assessment (RULA) method carried out on welding workers and the research method quantitatively and qualitatively then carried out statistical analysis, subjectivity and rula. The results showed that the final score of the posture of squatting, sitting and sitting in a chair had a score of 7, which means a high level of risk and needs immediate improvement. After evaluating the welding position improvement, there is a seat posture with a score of 3 which is a low risk level and requires changes. Same with the welding position sitting on the chair. The squat welding position with a score of 4 which is a low level risk level and sitting work posture has a score of 4 which means a low risk level, but requires a change for the future. From this study it was found that the relationship between Nordic Body Map and RULA was a continuity in squat work postures, which was found that this work posture had the highest risk of danger. Need to improve work posture in certain welding positions in this project or provide counseling about the dangers of work in the work posture if it continues

Ergonomic Risk

The medical manufacturing industry is currently one of the sectors with great potential growth in Malaysia, which offers numerous job opportunities to local and foreign workers. The growing proportion of workers in this industry means that a large number of workers are potentially exposed to ergonomic risk factors at the workplace, which may consequently affect their health. Thus, this study was carried out is to investigate the ergonomic risk factors and the prevalence of musculoskeletal disorders among male workers in a medical manufacturing company in northern Malaysia. Eight industrial workers (n = 8) were recruited from two Plastic Technology (PT) departments to participate in this study. Observations were made by recording the participants performing two tasks (manual lifting of containers and bags of chemicals) using a video camera at the PT1 and PT3 departments. The participants’ personal information and their job-related characteristics were first collected using a demographic questionnaire. Next, the Cornell Musculoskeletal and Hand Discomfort Questionnaire (CMDQ) was used to evaluate the prevalence of musculoskeletal disorders among workers while Manual Handling Assessment Charts (MAC) were used to assess the most common risk factors during the lifting operations. The results showed that the highest prevalence of musculoskeletal disorders among the male workers at the medical manufacturing company was at the lower back (83.17%), upper back (4.38%), right shoulder (3.49%), and left shoulder (3.49%). Based on the results of the MAC, 100% of the participants were at high risk of injury from postures in the vertical lift zones, torso twisting, and sideways bending. In addition, 87.5 and 62.5% of the participants were at high risk of injury based on their hand distance from the lower back and grip on the load, respectively. The results of this study can serve as a guideline to implement interventional ergonomics programmes at the workplace and improve the musculoskeletal health of workers in the medical manufacturing industry in Malaysia.

Rapid Entire Body Assessment

Determining the potential risks of musculoskeletal disorders through working postures in a workplace is expensive and time-consuming. A novel intelligent rapid entire body assessment (REBA) system based on convolutional pose machines (CPM), entitled the Quick Capture system, was applied to determine the risk levels. The aim of the study was to validate the feasibility and reliability of the CPM-based REBA system through a simulation experiment. The reliability was calculated from the differences of motion angles between the CPM-based REBA and a motion capture system. Results show the data collected by the Quick Capture system were consistent with those of the motion capture system; the average of root mean squared error (RMSE) was 4.77 and the average of Spearman’s rho (ρ) correlation coefficient in the different 12 postures was 0.915. For feasibility evaluation, the linear weighted Cohen’s kappa between the REBA score obtained by the Quick Capture system and those from the three experts were used. The result shows good agreement, with an average proportion agreement index (P0) of 0.952 and kappa of 0.738. The Quick Capture system does not only accurately analyze working posture, but also accurately determines risk level of musculoskeletal disorders. This study suggested that the Quick Capture system could be applied for a rapid and real-time on-site assessment.

Introduction: Musculoskeletal disorders are prevalent in work environments. Performing programs to identify and control the risk factors for musculoskeletal disorders and to carry out corrective actions to improve working conditions is important because of the impact on the health of the workforce.Methods: In this study, the presence of various shifts in the operating rooms and the training and justification of the employees of this department regarding its study and its objectives, the steps of the work of the operating room staff in various occupations were observed and existing documents and guidelines were reviewed. The main steps, including hierarchical analyzes of businesses, identifying errors in terms of each task and sub task, completing other parts of the work sheet, and determining the probability of human error and providing the prioritized control strategies in the next steps, was carried out. Results: Based on the results of Nordic questionnaire, age, work experience and higher weight were associated with musculoskeletal pain in most of the organs. Also taller was associated with back and waist pain and older age with pain and discomfort in the palms, knees and ankles (p <0.05). Based on the results of posture assessment, RULA 2 has a risk level of 4, 2 tasks Risk level 3 and 2 were risk level 2, which after the implementation of the interventions, a number of risk levels were eliminated in general and a number decreased. Conclusion: Despite the high risk of musculoskeletal disorders in this industry, ergonomic interventions reduced risk to the desired level.

Macroeconomic Indicator

Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.

This study intends to find out the mediating effect of organisational culture on the relationship between information system and sustainable performance of manufacturing sector in UAE. This study used AMOS-SEM software to develop mediation model that linking the mediating relationships between Information System, Organisational Culture and Sustainable operation Performance. Data was collected through questionnaire survey among the operation staff of Abu Dhabi manufacturing companies. A total 250 questionnaires were distributed however 205 were returned and only 200 are valid which indicates a response rate of 80%. The analysis found that TPS has positive but not significant effect to SP; OIS has positive but not significant effect to SP; FMW has a positive and significant effect on SP; SDS has a negative and not significant effect to SP and SP has positive but not significant effect OC. For the path relationship between the four exogenous variables (TPS, OIS, SDS, and FMW) and the mediator variable (OC), the results are TPS has positive and significant effect to OC; OIS has positive but not significant effect to OC; FMW has positive and significant effect to OC and SDS has positive and not significant effect to OC. Collectively, the five exogenous constructs (TPS, OIS, SDS, FMW and OC) explained 89% variation in operational performance and 86% of the variation in organisational culture. However, for a mediator, it was found that OC has no significant mediating effect on the relationship between TPS and SP; OC has no significant mediating effect on the relationship between OIS and SP; OC has no significant mediating effect on the relationship between SDS and SP and OC has no significant mediating effect on the relationship between FMW and SP. it can be concluded that there is a positive relationship between information system dimensions and operational performance. However organizational culture has no contributing any mediating effect to the relationship. These findings have contributed to the body of knowledge and could be shared among the UAE manufacturing practitioners.

Legal Principles

Despite wide legislation basis of regulating relations in work safety and workers’ health, one third of workplaces demonstrate exceeded allowable normal levels of workers’ exposure to occupational hazards and present occupational risk for health disorders.In accordance to national legislation acts, evaluation should cover factors of occupational environment and working process, and occupational risk is understood in context of mandatory social insurance. This approach has been formed due to mostly compensatory trend in legal principles of work safety in Russia by now. Implementation of new preventive concept of work safety, based on idea of risk management for workers, necessitates development of legal acts that regulate requirements to evaluation of occupational risk and its reports with consideration of changes in Federal Law on 30 March 1999 №52 FZ “On sanitary epidemiologic well-being of population”.Those acts can include Sanitary Rules and Regulations “Evaluation of occupational risk for workers’ health”, that will contain main principles of risk assessment, requirements to risk assessment, including its characteristics which can serve as a basis of categorizing the risk levels with acceptability.To standardize requirements for informing a worker on the occupational risk, the expediency is specification of sanitary rules “Notifying a worker on occupational risk”. These rules should contain requirements: to a source of data on occupational risk level at workplace, to informational content and to ways of notifying the worker. Specification and implementation of the stated documents enable to fulfil legal requirements completely on work safety — that will provide preservation and increase of efficiency in using work resources.
