The work environment appears as one of the dimensions in which social vulnerability develops and social and occupational vulnerability is defined. The literature does not include an assessment of quantified occupational vulnerability as it already exists in the case of social vulnerability. The aim of this paper is to identify and quantify the variables included in the Protocol for the Assessment of Vulnerability to COVID-19 in such a way that the result can be quantified and allows for a predictive effect on the degree of vulnerability. <strong>Methodology:</strong> The starting point is the design of a protocol proposal that includes 29 variables. Data is collected from a sample of 420 workers, quantifying the results according to each variable, the overall scores for each group of aspects assessed and, finally, the total score that estimates the degree of vulnerability according to established ranges. <strong>Results:</strong> Variables that have the highest coefficient and, therefore, the greatest weight in the probability of reaching a group of high or medium vulnerability are cardiovascular disease, cancer, and coagulation alteration. The weight of the labour aspects due to inadequate working conditions stands out. <strong>Conclusions: </strong>The results obtained with this protocol allow us to make a quantified assessment of labour vulnerability to COVID-19 by integrating individual variables of the worker, his working conditions and the preventive actions of his company against COVID-19, and can be useful as an Occupational Vulnerability Index (OVI).展开更多

A study was designed with the aim of analysing the perception of Tattoo Artists regarding their Occupational Health/Safety team (opinion about the support provided);as to find out what type accidents, symptoms and occupational diseases they have, in order to provide a better service. Methods: This is a mixed exploratory study, containing a quantitative observational (analytical, cross-sectional) and a qualitative component (Case Study). For the statistical analysis, predominantly non-parametric tests were used. The project was approved by the Ethics Committee and informed consent was obtained. Results: In terms of symptomatology/illnesses, musculoskeletal pathology is the most reported. In terms of accidents, cuts stand out. Several statistically significant relationships were found between the variables analysed. Discussion/Conclusions: The Occupational Health and Security services are considered insufficient by most of the Tattoo artists. It would be desirable that the Occupational Doctor has concrete knowledge regarding Tattooing, in particular semiology/pathology;makes recommendations in pharmacology and/or indicates which exams could be useful. In relation to the Safety Technician, it would be desirable also to have specific knowledge about the sector, making plausible suggestions for improvement.展开更多

The present s...Insertion of Sustainable Development Goals (SDGs) into higher education is an important concern. This article aims to address the influences of SDGs in higher and engineering educational system in Egypt. The present study focuses on SDGs 3, 4, 6, 7, 9, and 11. SDG 3 is related to occupational health and SDG 4 is related to higher education development. However, SDGs 6, 7, 9, and 11 are related to both mechanical and environmental engineering, and occupational safety. The study approach involves case risk analysis, investigations, and review for design concepts of occupational health and safety before and after the Coronavirus disease (COVID-19). A number of cross-sectional studies that constitute 125 multidisciplinary research plans (MDRPs) are grouped to monitor and evaluate two main factors which are an influence of involving SDGs into engineering education and selected curriculum of occupational health and safety. Then the results of these research-based studies, which performed over four academic years started from 2017 up to date 2021, are depicted and discussed. These results reveal the importance of interlink between engineering education and the intended SDGs. The latest 25 MDRPs demonstrate that Egypt response to alleviate the COVID-19 is rapidly pronounced specially on SDGs 3 and 4 simultaneously. However, those MDRPs show that neither record impacts nor delays on SDGs 6, 7, 9 and 11. The conclusions prioritize both the advanced educational mechanisms and verify the engineering curriculums to raise awareness of SDGs among both staff members and students in Egyptian universities. Finally, future work is recommended at the end of this article to focus on each specific goal to gain deep insight to state of the art for each SDG around globe using education development.展开更多

Materials and Methods: The study is cross-sectional and descriptive in a quantitative research design. The “Attitude Scale for Physicians toward Occupational Health and Occupational Diseases” developed by Kolcu et al. was used in the study (Cronbach’s α 0.94). Our study aimed to sample the entire country using the stratified sample selection based on geographical region. 349 family physicians were included in the study according to sample size (n: 349). Results: The mean age of the participants in the study was 37.77 ± 8.96 (min: 27, max: 65 years). Of the participants, 65.2% were male. Of the physicians, 33.8% were family medicine specialists, and 38.8% had occupational physician certificates. It was determined that the level of attitude of family physicians toward occupational diseases was insufficient. It was also found that awareness increased as age increased, and awareness and attitude levels did not change according to gender. No significant difference was found in the scale total scores and subdimensions of family physicians’ occupational health and occupational disease attitudes according to the regions they worked in Türkiye. Conclusion: It has been concluded that there is no difference in awareness among family physicians in regions where it is much more important to diagnose an occupational disease, especially in industrial regions. The number of family physicians with occupational physician certificates was very insufficient, and a significant number of those who had occupational physician certificates did not practice occupational medicine.展开更多

Modelling occupational outbreaks will be useful to guide the field investigation. Objective: To identify standard pathways for occupational epidemic outbreaks. Methods: In-depth critical appraisal of 57 occupational outbreaks. Standard pathways of occupational outbreaks were identified by analysing the similarity between out-breaks. The model’s accuracy and homogeneity were established through Fisher’s exact test and the Kappa Index. Results: The analysis allowed synthesizing the occupational outbreaks variability in 4 pathways. 92.98% of the analysed outbreaks could be allocated to one of those 4 types. The theoretical patterns showed a good adjustment with the analysed out-breaks: Type I (Kappa = 0.94 - 0.60), Type II (Kappa = 1.00), Type III (Kappa = 1.00 - 0.68) and Type IV (Kappa = 0.94 - 0.87). The probability of a given outbreak fitting with its three components in any of the theoretical pathways was 0.83. Conclusions: The incorporation of those pathways to the field occupational epidemiology will allow: 1) to provide early guidance to epidemiological, clinical and environmental studies focused on specific hypothesis of causality;2) to anticipate preventive measures;3) to contribute to an earlier and more efficient outbreak resolution.展开更多
文摘Objective:Through retrospective analysis of a case of occupational noise-induced hearing loss(NIHL)diagnosis and two-grade appraisal,this study explores the causes of inconsistency between diagnosis and appraisal conclusions,aiming to improve occupational health management.Methods:Data including occupational history,workplace noise exposure levels,pure-tone audiometry(PTA),and objective audiological tests were collected and analyzed.Results:Both municipal and provincial appraisals contradicted the initial diagnostic conclusion of“moderate occupational NIHL”.Conclusion:The diagnosis of occupational NIHL requires multidisciplinary expertise and is influenced by subjective factors.Appraisal institutions should adopt evidence-based approaches,integrate objective tests with PTA results,and comprehensively evaluate occupational exposure history to ensure scientific and impartial conclusions.

文摘Evidence on the association of occupational exposure to benzene,toluene,ethylbenzene,and xylene(BTEX)with hematologic and hepatic profiles were equivocal,and few studies have investigated overall effect of BTEX mixtures.Herein,significant higher concentrations(p<0.05)of hippuric acid,1,2-dihydroxybenzene,mandelic acid,trans,trans-muconic acid and phenylglyoxylic acid were found in petrochemical workers than the controls,in accordance with higher levels of hematologic and hepatic profiles found in petrochemical workers(p<0.05).Occupational exposure to individual BTEX was associated with elevated levels of white blood cell(WBC),lymphocyte(LYMPH),alanine aminotransferase(ALT),and gamma-glutamyl transferase(GGT).Further,the Weighted Quantile Sum Regression model and Bayesian Kernel Machine Regression model consistently identified a positive associa-tion between BTEX mixture exposure and WBC,LYMPH,and GGT.Xylene was the primary contributor to increased WBC,LYMPH,and GGT levels.Furthermore,BTEX exposure resulting in the increased inflammation indices were mainly related to perturbations of sphingolipid metabolism,biosynthesis of unsaturated fatty acids,and primary bile acid biosynthesis.Whereas metabolites mediated the correlation between BTEX exposure and liver function indiceswere related to the perturbations of biosynthesis of unsaturated fatty acids,arachidonic acid metabolism,sphingolipid metabolism,primary bile acid biosynthesis,etc.Our findings revealed potential health risk of occupational exposure to BTEX andmight help one to understand the link between BTEX exposure and hematologic and hepatic profiles.
文摘As the core department in medical institutions responsible for cleaning,disinfecting,sterilizing,and supplying reusable medical devices,instruments,and items,the quality of work in the disinfection supply center directly impacts medical safety and infection control effectiveness.Professional protective training for personnel is crucial to ensure operational quality in this department.Systematic training enhances staff awareness of occupational exposure risks,standardizes protective measures in procedures,reduces cross-infection risks caused by improper operations,and ultimately lowers infection transmission risks.This paper analyzes the core content,implementation approaches,and practical role of professional protective training for disinfection supply center personnel in infection control.It aims to clarify the significant value of such training,providing references for medical institutions to optimize disinfection center management and strengthen infection control systems,thereby contributing to improved overall medical safety standards.

文摘Occupational structural transformation is a common pattern during the steady growth of GDP per capita in major economies worldwide.In recent years,there has been a decline in the employment share of goods occupation and an increase in service occupation within the Chinese manufacturing industry,presenting a trend of occupational structural transformation and rapid development of service-oriented manufacturing.It is an important driving force and typical performance of the high-end,intelligent,and green development of the manufacturing industry.As a strategic general technology which leads the new round of technological revolution and industrial transformation,artificial intelligence(AI)has become a new fundamental force to accelerate the occupational structural transformation and service-oriented manufacturing development in China.Thus,this paper establishes a dynamic general equilibrium model with AI technology and occupational heterogeneity,showing the endogenous mechanism of occupational structural transformation.We find that when AI technology is biased towards goods occupation,and the elasticity of substitution between goods occupation and service occupation is less than 1,then AI will drive the transformation of occupational structure from goods to service within the manufacturing sector,increase the proportion of service-oriented manufacturing,improve labor productivity of manufacturing relative to service and stabilize the real output share of manufacturing.Promoting deeper integration of different occupations,intensifying R&D in AI technology and reducing labor mobility barriers between occupations can effectively accelerate the occupational structural transformation and industrial structural upgrading.We use theoretical analysis and numerical simulation method to show the theoretical mechanism by which AI affects occupational structural transformation and industrial structural transformation from a macroeconomic perspective,and put forward policy implications on how to promote the service-oriented manufacturing development and accelerate the construction of modern industrial system through AI innovation.

文摘With the development of the international education environment and the continuous reform of higher education in China,the working pace in universities is accelerating,with higher requirements for university work and increasingly apparent pressure on teachers.Young teachers in Chinese universities are prone to occupational stress.In addition to undertaking teaching,research,and other tasks,they feel anxious and at a loss when facing personal issues such as job promotion and taking care of their families.This article selects young teachers from some universities in China as research subjects and uses a questionnaire survey method to understand the current situation and sources of pressure on young teachers in universities,so as to focus on and alleviate their stress in a targeted manner.
文摘<strong>Introduction: </strong>Vulnerable is someone who can be hurt or receive injury, physically or morally. The work environment appears as one of the dimensions in which social vulnerability develops and social and occupational vulnerability is defined. The literature does not include an assessment of quantified occupational vulnerability as it already exists in the case of social vulnerability. The aim of this paper is to identify and quantify the variables included in the Protocol for the Assessment of Vulnerability to COVID-19 in such a way that the result can be quantified and allows for a predictive effect on the degree of vulnerability. <strong>Methodology:</strong> The starting point is the design of a protocol proposal that includes 29 variables. Data is collected from a sample of 420 workers, quantifying the results according to each variable, the overall scores for each group of aspects assessed and, finally, the total score that estimates the degree of vulnerability according to established ranges. <strong>Results:</strong> Variables that have the highest coefficient and, therefore, the greatest weight in the probability of reaching a group of high or medium vulnerability are cardiovascular disease, cancer, and coagulation alteration. The weight of the labour aspects due to inadequate working conditions stands out. <strong>Conclusions: </strong>The results obtained with this protocol allow us to make a quantified assessment of labour vulnerability to COVID-19 by integrating individual variables of the worker, his working conditions and the preventive actions of his company against COVID-19, and can be useful as an Occupational Vulnerability Index (OVI).
文摘Introduction/Objectives: As Tattoo is being more accepted, more professionals dedicate to it. A study was designed with the aim of analysing the perception of Tattoo Artists regarding their Occupational Health/Safety team (opinion about the support provided);as to find out what type accidents, symptoms and occupational diseases they have, in order to provide a better service. Methods: This is a mixed exploratory study, containing a quantitative observational (analytical, cross-sectional) and a qualitative component (Case Study). For the statistical analysis, predominantly non-parametric tests were used. The project was approved by the Ethics Committee and informed consent was obtained. Results: In terms of symptomatology/illnesses, musculoskeletal pathology is the most reported. In terms of accidents, cuts stand out. Several statistically significant relationships were found between the variables analysed. Discussion/Conclusions: The Occupational Health and Security services are considered insufficient by most of the Tattoo artists. It would be desirable that the Occupational Doctor has concrete knowledge regarding Tattooing, in particular semiology/pathology;makes recommendations in pharmacology and/or indicates which exams could be useful. In relation to the Safety Technician, it would be desirable also to have specific knowledge about the sector, making plausible suggestions for improvement.
文摘Insertion of Sustainable Development Goals (SDGs) into higher education is an important concern. This article aims to address the influences of SDGs in higher and engineering educational system in Egypt. The present study focuses on SDGs 3, 4, 6, 7, 9, and 11. SDG 3 is related to occupational health and SDG 4 is related to higher education development. However, SDGs 6, 7, 9, and 11 are related to both mechanical and environmental engineering, and occupational safety. The study approach involves case risk analysis, investigations, and review for design concepts of occupational health and safety before and after the Coronavirus disease (COVID-19). A number of cross-sectional studies that constitute 125 multidisciplinary research plans (MDRPs) are grouped to monitor and evaluate two main factors which are an influence of involving SDGs into engineering education and selected curriculum of occupational health and safety. Then the results of these research-based studies, which performed over four academic years started from 2017 up to date 2021, are depicted and discussed. These results reveal the importance of interlink between engineering education and the intended SDGs. The latest 25 MDRPs demonstrate that Egypt response to alleviate the COVID-19 is rapidly pronounced specially on SDGs 3 and 4 simultaneously. However, those MDRPs show that neither record impacts nor delays on SDGs 6, 7, 9 and 11. The conclusions prioritize both the advanced educational mechanisms and verify the engineering curriculums to raise awareness of SDGs among both staff members and students in Egyptian universities. Finally, future work is recommended at the end of this article to focus on each specific goal to gain deep insight to state of the art for each SDG around globe using education development.

文摘Background/Aim: This study evaluated family physicians’ attitudes toward occupational health and disease in Türkiye. Materials and Methods: The study is cross-sectional and descriptive in a quantitative research design. The “Attitude Scale for Physicians toward Occupational Health and Occupational Diseases” developed by Kolcu et al. was used in the study (Cronbach’s α 0.94). Our study aimed to sample the entire country using the stratified sample selection based on geographical region. 349 family physicians were included in the study according to sample size (n: 349). Results: The mean age of the participants in the study was 37.77 ± 8.96 (min: 27, max: 65 years). Of the participants, 65.2% were male. Of the physicians, 33.8% were family medicine specialists, and 38.8% had occupational physician certificates. It was determined that the level of attitude of family physicians toward occupational diseases was insufficient. It was also found that awareness increased as age increased, and awareness and attitude levels did not change according to gender. No significant difference was found in the scale total scores and subdimensions of family physicians’ occupational health and occupational disease attitudes according to the regions they worked in Türkiye. Conclusion: It has been concluded that there is no difference in awareness among family physicians in regions where it is much more important to diagnose an occupational disease, especially in industrial regions. The number of family physicians with occupational physician certificates was very insufficient, and a significant number of those who had occupational physician certificates did not practice occupational medicine.
文摘Background: The investigation of an occupational outbreak, once the index case has been identified, triggers a stress situation to epidemiologists. Modelling occupational outbreaks will be useful to guide the field investigation. Objective: To identify standard pathways for occupational epidemic outbreaks. Methods: In-depth critical appraisal of 57 occupational outbreaks. Standard pathways of occupational outbreaks were identified by analysing the similarity between out-breaks. The model’s accuracy and homogeneity were established through Fisher’s exact test and the Kappa Index. Results: The analysis allowed synthesizing the occupational outbreaks variability in 4 pathways. 92.98% of the analysed outbreaks could be allocated to one of those 4 types. The theoretical patterns showed a good adjustment with the analysed out-breaks: Type I (Kappa = 0.94 - 0.60), Type II (Kappa = 1.00), Type III (Kappa = 1.00 - 0.68) and Type IV (Kappa = 0.94 - 0.87). The probability of a given outbreak fitting with its three components in any of the theoretical pathways was 0.83. Conclusions: The incorporation of those pathways to the field occupational epidemiology will allow: 1) to provide early guidance to epidemiological, clinical and environmental studies focused on specific hypothesis of causality;2) to anticipate preventive measures;3) to contribute to an earlier and more efficient outbreak resolution.
