Investigating the relationship between body structure status, work activity type, and the prevalence of musculoskeletal disorders among detergent industry workers.

The physical condition of workers' body structure and assigned duties, can contribute to the prevalence of musculoskeletal disorders. This study aimed to investigate the relationship between body structure status, type of work activity, and the prevalence of musculoskeletal disorders among workers in the detergent industry. This cross-sectional study involved 148 industrial workers selected based on inclusion criteria and their medical checkup records. Data collection for the study included a demographic information questionnaire, a body map questionnaire, and an assessment of the workers' musculoskeletal system conducted by three physiotherapists simultaneously. 54.1% of the participants had a total body structure score classified as poor or fair. The neck region showed the highest prevalence of musculoskeletal disorders (51.4%), followed by the lower back region (35.1%). Significant associations were found between abnormalities in the upper and middle limbs of the body and the prevalence of pain in the right shoulder region (Fisher/F = 9.29, P≤0.05) as well as the intermediate back region (F = 10.28, P≤0.01). Office workers experienced a higher prevalence of neck pain than workers in the product line and technical roles, with a statistically significant Odds Ratio (OR) ranging between 2.7 and 6.6 times. Conversely, industrial workers who operate powered machinery showed a higher prevalence of pain in the left shoulder (OR = 3.93) and left foot (OR = 4.07). Meanwhile, workers involved in loading and unloading tasks had a higher prevalence of pain in the middle back (OR = 3.61) and right foot (OR = 4.5) compared to office workers. The prevalence of pain in the right shoulder and middle back may be due to abnormalities in the upper and intermediate body structure. Production line workers reported a higher prevalence of pain in the left shoulder, middle back, and foot compared to office workers.

Breaking the burnout cycle: Association of dispositional mindfulness with production line workers' job burnout and the mediating role of social support and psychological empowerment

Burnout among production line workers has become an issue for their physical and mental health and for the productive efficiency of companies. However, this large group of workers has received insufficient attention, particularly in exploring how employees' dispositional factors are associated with burnout. Therefore, this study aimed to examine the association between dispositional mindfulness and job burnout and the potential mediating roles played by perceived social support and psychological empowerment. Participants in the study included 780 production line workers recruited from a foreign company in China. Participants completed measures related to dispositional mindfulness, perceived social support, psychological empowerment, and job burnout. The results showed that (a) dispositional mindfulness was significantly related to lower burnout (β = −0.446, 95% CI [-0.552, -0.340]); (b) perceived social support (β = −0.073, 95% CI [-0.126, -0.025]) and psychological empowerment (β = −0.106, 95% CI [-0.171, -0.058]) mediated this association individually; and (c) perceived social support and psychological empowerment had a serial mediating effect in this context (β = −0.055, 95% CI [-0.095, -0.028]). This study revealed the association between dispositional mindfulness and job burnout, with an additional focus on how dispositional mindfulness correlates with other resources, such as perceived social support and psychological empowerment.

Using a shoulder exoskeleton in slaughterhouse work: Expectations, experiences, and feasibility

BackgroundWork in the slaughterhouse industry increase the risk of shoulder disorders due to high occupational mechanical exposures. Assistive devices, such as exoskeletons, have been developed to reduce the mechanical exposures, but few studies have investigated exoskeleton's feasibility, when used in a workplace setting. ObjectivesThe objective was to explore managers' and workers' expectations and experiences related to using a shoulder exoskeleton, and to evaluate its feasibility compared to an existing assistive device (a ‘lifting glove’) at a Danish slaughterhouse. ParticipantsThe participants included 26 production line workers and their managers at a packaging department at a large slaughterhouse facility. MethodsIn a 5-month field study, data on worker's expectations and experiences of using a shoulder exoskeleton, was compared to a lifting glove and to working without any assistive device. Data was collected using semi-structured interviews, questionnaires, and on-site observations. ResultsExpectations were that shoulder exoskeletons would reduce the mechanical exposure and strain in workers. Some managers also expected that workers could handle more weight/produce more and that the need for job rotation could be reduced. Workers reported the exoskeleton to ‘straighten the body’, and reduced strain, but e others experienced no perceived support or found donning and doffing too time consuming. ConclusionWe found different expectations as to what the shoulder exoskeleton should achieve. This could influence the evaluation of the feasibility of using a shoulder exoskeleton in slaughterhouse work. To facilitate the feasibility of exoskeletons it is important to explicate different expectations and to allow for individual tailoring in its implementation.

A Study On Work Stress Among Cement Manufacturing Workers: An Empirical Analysis

This empirical study investigates the prevalence and determinants of work-related stress among cement manufacturing workers. The cement industry, characterized by physically demanding tasks and potentially hazardous environments, presents a unique context for examining the psychosocial factors contributing to occupational stress. The research employs a mixed-methods approach, combining surveys and in-depth interviews, to gather comprehensive data on stress levels, job characteristics, coping mechanisms, and their impacts on workers' well-being. The sample comprises a diverse cross-section of cement industry employees, including production line workers, supervisors, and managerial staff, from multiple manufacturing facilities. Quantitative analysis utilizes validated stress assessment tools and regression models to identify significant predictors of work stress. Qualitative data from interviews offer nuanced insights into the subjective experiences and coping strategies of individuals facing various stressors in their work environment. Preliminary findings suggest that factors such as high job demands, limited autonomy, insufficient social support, and safety concerns significantly contribute to heightened levels of work-related stress among cement manufacturing workers. Additionally, the study highlights the importance of individual coping strategies, organizational interventions, and social support networks in mitigating the negative impacts of stress on employee well-being. This research not only contributes to the growing body of literature on occupational stress but also provides practical implications for both management and policy makers in the cement manufacturing industry. Recommendations for targeted interventions, improved work processes, and enhanced support systems are discussed to foster a healthier and more productive work environment for all employees in the sector. This study underscores the need for continued attention to the well-being of workers in physically demanding and potentially hazardous industries.

The Relationship between Job Fatigue and Fine Motor Skills in Cable Car Company’s Production Staff

Background and objective: Job fatigue is considered one of the factors affecting the performance and the productivity of workers in work environments. Therefore, the objective of the present study was to investigate the relationship between job fatigue and its dimensions with fine motor skills in the production line workers of Sabzevar Cable Car Company. Participants and methods: One hundred and forty-eight workers of the production line of Sabzevar Car Company were selected as a sample. The level of occupational fatigue of workers was measured using the standard questionnaire of Excessive Occupational Fatigue. In addition, manual and sorting skills of workers were estimated through Board test. In order to analyze the research data, Spearman's correlation coefficient test was used. Results: The results of the Spearman correlation coefficient test showed that there were negative and significant relationships between job fatigue and the components of hand and finger dexterity skill, including manual skills (r = 0.188, P ≤ 0.022) and sorting skill r (r = -0.246, P ≤ 0.003). Also, a statistically significant relationship was observed between the dimensions of fatigue and coping skills (P≤0.05). Conclusion: According to the results of the present research study, we recommend that employers prevent the occurrence of worker fatigue in industrial environments through providing conditions such as shift breaks and performing short-term activities with low intensity. Otherwise, in order to prevent accidents and the production of defective products, tired workers should refrain from performing fine manual activities such as assembling.

Investigating the relationship between sleep quality and stress, anxiety and depression in shift workers of one of the food industries

Introduction: Shift work among industrial workers can lead to poor sleep quality, which instead is associated with stress, anxiety, and depression. This study aimed to investigate the relationship between sleep quality and stress, anxiety, and depression in shift workers in one of the food industries.
 Materials and Methods: The participants in this descriptive-analytical study were 208 production line workers in one of the food industries. Data were collected using a demographic questionnaire, Pittsburgh Sleep Quality Questionnaire (PSQI), and depression, anxiety, and stress (DASS-21). Spearman's statistical test was used to investigate the relationship between sleep quality and depression, anxiety, and stress. The data were analyzed using SPSS-23 software.
 Results: About 42% of workers reported undesirable sleep quality (score more than 5). Almost half of the workers reported a level of normal stress, anxiety, and depression. The results showed that there is a positive and significant correlation between sleep quality and stress (r=0.20, P<0.01) and sleep quality and depression (r=0.172, P≤0.01) so that the quality of sleep, stress, and depression interact with each other and have a mutual effect.
 Conclusion: According to the results of this study, reducing stress and depression can improve the sleep quality of workers, and in turn, good sleep quality can lead to reducing stress and depression in shift workers. Therefore, identifying the influencing factors and corrective strategies to reduce stress, anxiety, and depression can play an important role in improving the sleep quality of shift workers.

“Assessing exposure of printing factory workers in thailand to selected heavy metals using urine and hair as non-invasive matrices”

BackgroundThere are few thorough studies on the extent and inter-element relationships of heavy metal contamination in printing factory workers, especially in developing countries. The objective of this study was to determine the levels of eight heavy metals, including arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), cobalt (Co), lead (Pb), mercury (Hg), and manganese (Mn), in urine and scalp hair of printing industry workers, and assess inter-element correlations.MethodsWe examined a total of 85 urine samples and 85 scalp hair samples (3 cm hair segments taken from near the scalp) in 85 printing workers from a printing house in Bangkok, Thailand. We used an interviewer-administered questionnaire about participants’ printing techniques, work characteristics, and work environment. Urine and scalp hair samples were analyzed for levels of each element using the inductively coupled plasma optical emission spectrometry (ICP-OES) technique.ResultsAs, Cd, Cr, Ni, Pb were detected in urine with the geometric mean concentration range of 0.0028–0.0209 mg/L, and Hg, Pb, Ni, Cd, Co, Mn, Cr were detected in hair samples (0.4453–7.165 mg/kg dry weight) of printing workers. The geometric mean Ni level was significantly higher in the urine of production line workers than back-office personnel (0.0218 mg/L vs. 0.0132 mg/L; p = 0.0124). The other elements did not differ significantly between production line and back-office workers in either urine or hair. There was also a strong, statistically significant positive correlation between Ni and Co levels in hair samples of workers (r = 0.944, p < 0.0001).ConclusionsAverage concentrations of most of the metals in urine and hair of printing workers were found to be above the upper reference values. The significantly higher concentrations of Ni in production line workers might be due to more exposure to printed materials. A strong inter-element correlation between Ni and Co in hair samples can increase stronger health effects and should be further investigated. This study reveals possible dependencies and impact interactions of heavy metal exposure in printing factory workers.

Pengukuran Produktivitas dengan Menggunakan Metode Objective Matrix pada Proses Produksi UD. Kopi Teungku Aceh

UD. Teungku Aceh Coffee is a business engaged in coffee production. In the November 2020-October 2021 period, this business has not been able to achieve the predetermined production target, which is 300 kg per day and 7,000 kg per month. The purpose of this study was to measure partial productivity in the production process using the Objective Matrix (OMAX) method. The second objective is to provide recommendations for improvement of the ratio that causes a decrease in productivity based on fault tree analysis (FTA). The criteria measured are the use of raw materials, labor hours, production line workers, machine working hours and electrical energy consumption. Based on the results of the OMAX calculation, the lowest ratio score is the ratio 1, which means that it causes a decrease in productivity in the UD production process. Kopi Teungku Aceh is ratio 1. Recommendations for improvement are given to increase productivity in ratio 1, namely, forming an inspection section as a raw material inspection division by making an analysis report (LA) as evidence that raw material inspection has been carried out, making a firewood storage area in the factory yard that is empty, performs a mixed drying process between natural and automatic drying and ensures the availability of suppliers in the timely delivery of raw materials.

The use of electromyography and kinematic measurements of the lumbar spine during ergonomic intervention among workers of the production line of a foundry.

PurposeWorkers who perform repetitive movements are exposed to many risk factors leading to the occurrence of lumbar back pain. The aim of the research was to answer the question whether the ergonomic instruction conducted by a physiotherapist would change the tested range of motion of the segments of lumbar spine and the symmetry of the work of the torso and upper limbs muscles during work performed by foundry employees.MethodsThe study included 12 foundry production line workers with musculoskeletal pain. The workstation was built in the laboratory that perfectly simulates work on the production line. The workers performed two activities from their daily work, i.e. transferring and moving a casting. They were then given ergonomic instruction by a physiotherapist and performed the assigned tasks again. During the activities, the electromyographic signal from five muscles was recorded in terms of symmetry of their work. The maximum angular ranges of the motor segments of the lumbar spine were measured using gyroscopes.ResultsAfter the ergonomic instruction, the contralateral imbalance of muscle activity decreased statistically significantly during the first phase (p = 0.0004), second phase (p = 0.0002) and the third phase (p = 0.0069) of transferring the casting. While moving the casting , only erector spinae showed statistically significantly (p = 0.0131) more symmetrical work after the ergonomic instruction. During the transfer of the casting, statistically significantly lower values of the ranges of motion between the segments were obtained after carrying out the ergonomic instruction for the left (p = 0.0231) and right (p = 0.0032) lateral flexion. The ranges of movement between the segments differed statistically significantly for the flexion (p = 0.0117), extension (p = 0.0469) and left (p = 0.0031) and right lateral flexion movements (p = 0.0012).ConclusionConducting ergonomic instruction consisting in teaching the correct performance of a movement task reduced the contralateral imbalance of muscle activity and changes the ranges of movement of L1-S1 segments. The task of optimizing the load on the musculoskeletal system, including the lumbar spine, should be carried out by means of appropriate ergonomic instruction and multi-pronged measures, including analysis of the health of employees, their working environment and physical activity outside the workplace. Electromyography and measurements of the range of movement of the lumbar spine appear to be good tools for the evaluation of workplace ergonomics.

The Effect of Occupational Health Risk Perception on Job Satisfaction.

This study explored the relationship between occupational health risk perception and job satisfaction. Based on the job demand-resources model and resource conservation theory, eight hypotheses were proposed in this study. In a survey of 237 production line workers and managers, we found that perceived occupational health risks significantly negatively affected job satisfaction. Both work stress and organizational commitment mediate the relationships between perceived occupational health risks and job satisfaction. We also examined whether safety culture could weaken the negative impact of perceived occupational health risks on job satisfaction. However, the results of our study did not support this hypothesis. This study not only helped managers to realize the hazards of occupational health risks, but also encouraged employees to actively participate in safety construction and pay attention to their own health. In addition, we also put forward some targeted intervention measures to reduce the negative impact of perceived occupational health risks on job satisfaction. Therefore, this study had certain practical implications.

MEASURING FIRM PERCEPTION TO ADAPTATION of INDUSTRY 4.0: THE CASE OF TURKEY

Purpose: This study aims at examining the perceptions of various layers within a firm toward integrating Industry 4.0 applications in production. Methodology: We follow a case study approach to obtain detailed information about the selected firm. For this purpose, we focus on three sectors as machinery, food, and automotive spare parts having a strategic role in digital transformation. In total, 12 interviews with blue-collar workers, engineers, and managers are conducted in five different companies. Findings: The results of the study are twofold. As for the senior management layer and engineers, the adaptation of Industry 4.0 applications to the firm will increase the firm efficiency. As far as its effect on employment is considered, it has been determined that the concept is not fully understood, especially by blue-collar workers, and it is not known how it will contribute to production. Production line workers, therefore, think that they will experience the threat of losing their jobs with the implementation of Industry 4.0 applications. Originality: Despite its importance, the number of studies dealing with the difficulties, benefits, opportunities, and threats of adopting Industry 4.0 especially for developing countries is still few. This study, therefore, closes this gap by conducting a comprehensive study with various layers of the firm.

Identifying management practices that drive production-line workers’ engagement through qualitative analysis

Introduction: Engagement research - most often defined by a worker’s psychological state of vigor, dedication, and absorption - pays little attention to production-line workers. This study therefore explores factors that drive workers’ engagement with health and safety (H&S) in a production-line context as well as their perception of managerial influence Furthermore, the study adds to the body of research by exploring H&S engagement concepts through the use of qualitative research methods. Method: 38 semi-structured interviews were conducted and analyzed through template analysis to identify themes that promote and hinder engagement. Results: The main engagement drivers were found to be: (a) the displayed safety focus of the company in organizational and social aspects; (b) the quality of the communication approach with respect to quality, consistency and direction; and (c) the environment encompassing the relationship between workers and supervisors and peers as well as the psychological environment. Notably, a trusting relationship between supervisors and workers appeared to be the most influential driver in determining engaged H&S behavior. Discussion and impact in industry: The study highlights factors that could be adapted to improve engagement and consequently enhance H&S approaches. Originality: The study reported in this paper offers a unique insight into individual production workers’ perceived drivers of H&S engagement using Qualitative Analysis. Practical applications: The study identified the important role that supervisors play in workers’ H&S engagement levels and what skills they need to employ to enhance workers’ engagement in general and in the context of H&S behavior and performance. Furthermore, the importance of psychological and sociological factors in safety approaches are highlighted and were found to be key for creating safer workplaces.

“Pulling the sheep’s wool”: The labour of online thrift in a Chinese factory

This paper draws on data collected during ethnographic fieldwork in a factory in south-east China to describe the significance of a group of activities colloquially known as “pulling the sheep’s wool” ( haoyangmao). This wide-ranging set of thrift-oriented practices involves gaining rewards and discounts by collecting various credits and points, most often through activities conducted on online shopping, news and payment platforms. Recent studies have sought to reposition thrift as a morally-infused consumptive practice for the creation of value, through which the concept of the house is enacted. However, this paper demonstrates how thrift is viewed by labourers as a kind of “work”. As such, it is able to act in a factory environment largely unmoored from notions of domesticity, instead delineating social boundaries between production line workers and managers, fostering communal behaviours amongst labourers and—through a process of earmarking—allowing for workers to direct a greater share of their wages toward household economies. We argue that this conception of thrift as labour actually reworks the way that consumption conjoins with production, challenging our received understandings of consumption, while also providing new possibilities for the creation of both value and personhood.

Towards innovative work behavior through knowledge management infrastructure capabilities

PurposeThis study proposed a model based on knowledge management infrastructure capabilities (KMICs) to explore that how functional flexibility (FF) and knowledge sharing (KS) plays a mediating role between KMIC and innovative work behavior (IWB) among production-line workers.Design/methodology/approachData were collected from 894 workers through self-administered questionnaires from manufacturing businesses. The outcomes of the study revealed that KMIC has a significant and positive relationship with IWB. Second, FF and KS fully mediate between KMIC and IWB. Finally, the moderating role of KS between KMIC and FF was also supported by this study.FindingsThis study offers the empirical evidence on how to flourish the mechanism of FF and KS in manufacturing concerns. Additionally, some facts are also highlighted by this study that should be eloquent options for HR managers to understand the nexus of KMIC, KS and FF for enhancing the IWB among production-line workers. Moreover, this study contributed to noteworthy inferences for management by focusing on KMIC as a fundamental organizational level factor for IWB via KS and FF.Originality/valueThis is the first study in the which emphasis on KMIC for explaining IWB through employee FF and KS in settings such as manufacturing concern where the implementation of new working methods is necessary.

Sustainability performance model: A case study of pneumatic nipple hose connector

Sustainability concept was first introduced by Dr Harlem Brundtland in 1980’s promoting the need to preserve today’s mother nature for the sake of our future generations. There are three main evaluation criteria’s involved in sustainability approach namely economics, environmental and social. In consumer product manufacturing industry, the economics criteria are measured by consider the total manufacturing costs where it evaluates the economic sustainability of a company in a long term. The impact to the environment during manufacturing process can be used to measure the environment criteria. The social criteria are complicated to evaluate. But focusing at production line workers’ health who works at the production line can be used to evaluate the social criteria because it gives direct impact to their performance. In this paper, the sustainability concept is applied at the production line in the production of a pneumatic nipple hose connector. The evaluation criteria which has been considered are total manufacturing costs, environmental impact, ergonomics impact and also energy used for manufacturing. This study involves machine learning optimization by using neural network model which carried out in two stages. The first stage is to predict the results based on experimental works. The second stage is by using inversed neural network model to determine the optimum cutting parameters so that it can be used to manufacture the pneumatic nipple hose connector. Through these stages, optimization of the manufacturing procedures to produce pneumatic nipple hose connector already considered the criteria for sustainability.

High-involvement HRM practices and innovative work behavior among production-line workers: mediating role of employee's functional flexibility

PurposeFollowing “AMO” framework and resource-based theory (RBT), the current study empirically examines the relationships between high-involvement human resource management (HI HRM) practices, employee functional flexibility (FF) and innovative work behavior (IWB). Furthermore, the mediating effect of FF has also been tested.Design/methodology/approachDescriptive statistics, correlation, hierarchical regression analysis, baron and Kenny, PROCESS Macro and Sobel Test approach were used on a sample of 894 employees of manufacturing concerns.FindingsFindings revealed a direct effect of HI HRM practices on FF and IWB. In addition, the results confirm that FF positively mediates between HI HRM practices and IWB. Furthermore, three dimensions of HI HRM practices, i.e. ability-enhancing (AE), motivation-enhancing (ME) and opportunity-enhancing (OE) HRM practices also predicted FF and IWB.Practical implicationsThis study not only offers the empirical evidence to validate the findings of past researchers, but also provide insight how HI HRM practices flourish the mechanism of FF in manufacturing concerns. Furthermore, this study highlighted some interesting facts that should be meaningful options for HR managers to enhance the level of employees' FF and IWB.Originality/valueAlthough the empirical evidence is well established that HI HRM practices have a substantial contribution for organizational performance, however, there is lack of studies that empirically examine the associations among HI HRM practices, employee's competencies and behaviors, as well as the mechanism through which HI HRM practices affect work related innovative behavior. Finally, in distinguishing from the past studies, this study explores HI HRM practices as an important predictor of FF in addressing the IWB.

Leadership concepts in manufacturing environments: A brief historical review and conclusion with recommendations for education and training of I-O psychologists

Viewing production-line workers from a historical standpoint, the attention on manufacturing in the 19th and into the 20th centuries was on production (Fifelski, 2014) and production-oriented leadership style, in contrast to employee-oriented leadership style (Likert, 1961; see also Kosicek, Soni, Sandbothe, &amp; Slack, 2012).Around the turn of the 20th century, changes took place, and it appears as if two different approaches were taken in manufacturing environments: research–practitioner-based leadership approaches and management-based leadership approaches; the latter approach is less a leadership style and more a social management philosophy em+phasizing business operation (Vitolla, Rubino, &amp; Garzoni, 2017). This review should bring awareness that industrial and organizational (I-O) psychologists once took on the lead to major successes that arose from work in manufacturing companies; however, today there is hardly any contribution by I-O psychologists to the manufacturing sector.

Oral Health Status and Oral Health-Related Quality of Life (OHRQoL) among Steel factory workers of Visakhapatnam-A cross-sectional study.

Introduction:The occupational environment influences oral health to a greater extent. The unique environment in the steel factory might influence oral health and oral health-related quality of life of its workers, especially those who are exposed to its environment.Aim and Objectives:To determine oral health status and Oral Health-Related Quality of Life among production line and administration workers of a steel factory and assess their relationship with occupation exposure.Method:A cross-sectional study was conducted among 533 production line and 517 administration workers of the steel factory aged 31–60 years using simple random sampling. The collected data includes information on demographic factors, adverse habits of the study subjects, and oral health-related quality of life using Oral Health Impact Profile-14 (OHIP-14). The oral health status was assessed using the WHO oral health assessment form 2013.Statistical Analysis:SPSS Version 20 was used for statistical analysis. A student t-test was done to compare means.Results:The prevalence of dental caries is 62.5% in the production line and 74.9% in administration workers, and the prevalence of periodontal status is 91.6% and 74.8%, respectively. The mean of OHIP-14 was 2.13 ± 0.73 in the production line and 2.33 ± 0.77 in administration workers. All domains of OHIP-14 were found to have high statistical significance with dental caries, periodontal pocket depth, loss of attachment, oral mucosal lesions, dental erosion, and dental trauma in both study groups (P < 0.001).Conclusion:OHIP-14 scores were related significantly with oral health status indicators in both study groups. The prevalence of the periodontal disease, oral mucosal lesions, and OHIP-14 scores was found to be significantly higher among production line workers.
