Evaluation of Workers� Workload at Neyshabur Ceramic and Tile Factory 2017

Background and Aims: Workload can be defined as the worker's required capacity to meet a special level of performance to do a task. Workload is increasing by factors such as type of job, repetition of task, intensity, and duration and psychological factors of the work. This study aimed to evaluate workers� workload at Ceramic Tile factory. Materials and Methods: This cross-sectional descriptive-analytic study was conducted on 120 workers of Neyshabur ceramic and tile factory in. NASA-TLX standard questionnaires was respectively used. Then, the obtained data was analyzed using SPSS-20 software and descriptive statistics and Pearson-Spearman correlation test. Results: Results of NASA-TLX revealed that performance, frustration and physical demands showed respectively high mean scores of 87,76 and 75 and the least score was 51. Therewere significant correlations between marriage, level of education, work experience and the hours of work per week with mean mental workload score. Conclusion: It was revealed that workload was high. This result was also confirmed by observational evaluation. Based on our results, workload management programs should be focused on omitting or reducing improper working workplace

The Relation between Shift Work, Fatigue and Sleepiness and Accidents among Workers in Sugar Factory

Background & Objectives : Shift work has been recognized as an important tool for organizing of work in developing countries. The disturbed sleep, fatigue and accident is the most common health ‐ related effects of shift work. The aim of this study was to evaluate the severity of fatigue and sleepiness between shift and non-shift workers and its relation to occupational accidents. Methods : This cross-sectional study was carried out in Sugar Factory located in Isfahan city. Using simple randomized sampling technique, 120 workers with an average age of 32 years for night work and 33 years for day work were selected. ISI and Epworhth questionnaires and Fatigue Scale were used to determine the prevalence of symptoms of Sleepiness and fatigue. The data was analyzed using SPSS20 software and applying descriptive statistics, Pearson correlation test and t-test. Results : Results showed that the fatigue score among shift workers was 4.41. In all symptoms associated with fatigue average scores of night shift were higher than day shift and there was a significant difference between them. There was a significant relation between the symptoms of fatigue with insomnia severity index and accidents. Conclusion : The rate of fatigue and the number of the work accidents was more in the shift workers compared with non shift workers. The rate of accidents was more common in people who had more severe drowsiness

The Prevalence of Chronic Fatigue Syndrome in Radiotherapists

Background: Ionizing radiation is one of the hazardous agents in the work place. It can cause serious and irreversible damage to the people exposed to it. Working in such environments can also causes chronic fatigue syndrome (CFS). The aim of this study was to investigate the prevalence of CFS in radiotherapists. Methods: This study selected all men and women exposed to X-ray as the exposed group and nurses working in the same hospital as the control group. The sample size was considered of 46 radiotherapists and 46 nurses. Data on demographic characteristics and chronic fatigue syndrome were collected by the questionnaire. Results: The mean CFS score in all participants was 10.64±4.77. About 17.39% of them had fatigue syndrome. There was no significant difference between two groups in terms of fatigue syndrome (p=0.47). radiotherapists with more than 20 image taking per day had higher mean CFS; however, this relationship was not statistically significant (P>0.05). Conclusion: Chronic fatigue is multifactorial phenomenon in health care personnel. Workload is more important factor in development of chronic fatigue in radiotherapists

The Relation between Heat strain and hydration status among

Introduction: during the physical activity in hot environments, sweating with evaporation, the important physiological response of the body&nbsp; increases which can be lead to dehydration . Long-term water shortages could adversely affect vital organs. The aim of this study was to determine heat stress and dehydration status of workers in hot workplaces. Methods: This cross sectional study was done on 90 workers of workers in sugar factory which were exposed to heat. Heart rate and oral temperature were respectively measured using a heart rate meter and an oral thermometer. WBGT index was recorded and the HSSI questionnaire was completed simultaneously, in order to assess dehydration level was measured of refractometer. Data obtained from this study were analyzed using compare means and t-test, paired t-test tests by SPSS 20 software Results: Heat stress exceeded the national and international recommended limits based on the WBGT index in 44% of cases of workstations. According to this study, 8.5% of our population had some degree of dehydration.63.4% of them were significantly dehydrated (urine SG>1.020) and 28% of them were severely dehydrated (urine SG>1.030) and the mean specific gravity was 1.025&plusmn;0.043 The correlations between heat strains, Urine Density and heat stress including oral temperature, heart rate were significant(p<0.05). Conclusion: A high percentage of the study population had some degree of dehydration that based on the results is worrying. It seems that planning in order to control of heat stresses by replace drinking is necessary

Effect of Fatigue on Job Performance and Musculoskeletal Disorders among Power Plant Staff

Background: The sustainability and strength of an organization strongly depends on the mental, physical, and physiological health of its employees. The purpose of this study is to investigate the effect of fatigue and stress on the incidence of musculoskeletal disorders, job performance and their relationship considering some demographic variables in this society. Methods: This cross-sectional analytical study was conducted in 2017. The study populations were administrative employees of the power plant, and sampling was done by census method. Three standard questionnaires about job fatigue and job performance and Nordic questionnaire were distributed among 62 employees. Data were analyzed by SPSS 20; descriptive statistics and Pearson correlation test. Results: All 62 samples were male, and the mean and standard deviation of their age were 41.52 (7.71) years and the mean of work experience was 12.13 (6.25) years. According to the results, 53% of the samples showed high and very high fatigue; the fatigue score was 3.96 that indicated the moderate level. The job performance score was 38.3, which was considered at the low level. Also, there was an inverse and significant relationship between fatigue and job performance (P = 0.03, r = -0.37), and there was a significant relationship between fatigue, performance and neck and back areas (p <0.05)

The relationship between fatigue, stress and job performance with some demographic variables in dental prosthesis technicians

Background and Aims: Making dental prostheses is sensitive and accurate work and requires powerful and skilled hands. Because of this, the dental prosthesis technicians may suffer harmful effects such as stress and fatigue during the course. The aim of this study was to investigate fatigue, stress and job performance and their relationship with some demographic variables in this community. Materials and Methods: The present study was cross-sectional and done in 2016. The study population was a group of dental prosthesis technicians that had participated in a national congress in Tehran. Sampling was done by census Two standardized questionnaires on the subjects of fatigue and stress which were distributed among 100 female and male participants and sampling was done by census. Then, the obtained data was analyzed using SPSS16 software and applying descriptive statistics, Pearson correlation test, and ANOVA, T-test. Results: From the 100 samples, there were 16 females and 84 males with mean age 34.71&plusmn;7.90 and average work experience of 10.82&plusmn; 9.01 years. 82 percent of the subjects were married and 42 percent of them were smokers. The results showed that 100 percent of dental prostheses technicians were facing with moderate to severe stresses. The stress and fatigue scores in married ones were higher than the single ones. The results showed a significant relationship between smoking, stress, and fatigue scores (P<0.05). Conclusion: According to the high level of job stress in the dental prostheses technicians, this problem must be considered, minimized, and more attention should be paid to their psychological and emotional problems
