    The purpose of this paper is to (1) document the definition of defense-in-depth and the pproach that will be used to assure that its principles are satisfied for the NGNP project and (2) identify the specific questions proposed for preapplication discussions with the NRC. Defense-in-depth is a safety philosophy in which multiple lines of defense and conservative design and evaluation methods are applied to assure the safety of the public. The philosophy is also intended to deliver a design that is tolerant to uncertainties in knowledge of plant behavior, component reliability or operator performance that might compromise safety. This paper includes a review of the regulatory foundation for defense-in-depth, a definition of defense-in-depth that is appropriate for advanced reactor designs based on High Temperature Gas-cooled Reactor (HTGR) technology, and an explanation of how this safety philosophy is achieved in the NGNP.

    Not all operational radiation protection situations lend themselves to simple solutions. Often a Radiation Protection Program must be developed and implemented for difficult situations. A defense in depth approach to radiation protection was developed for 125I production activities. Defense in depth relies on key radiation protection elements that tend to be mutually supportive and in combination provide reasonable assurance that the overall desired level of protection has been provided. For difficult situations, defense in depth can provide both a reasonable and appropriate approach to radiation protection.

    KALIMER is one of sodium-cooled fast reactor and being developed by Korea Atomic Energy Research Institute (KAERI), was developed and suggested in this paper. Developed OPT is for the defense-in-depth level 3, core heat removal safety function. Using OPT method, the evaluation of defense-in-depth implementation for the design features of KALIMER reactors were tried in this study. To utilize the design information of KALIMER, challenges in OPTs which are under development in this study, were identified based on the system physical boundaries. This approach make the identification of possible and postulated challenges much clear and this will be a benefit to further identification of provisions in KALIMER design. OPTs for other levels of defense-in-depth and other safety functions are under development.

    An initiating event may lead to a severe accident if the plant safety functions have been challenged or operators do not follow the appropriate accident management procedures. Beyond design basis accidents are those corresponding to events of very low occurrence probability but such an accident may lead to significant consequences. The defense in depth approach is important to assure nuclear safety even in a severe accident. Plant Damage States (PDS) can be defined by the combination of the possible values for each of the PDS parameters which are showed on the nuclear power plant simulator. PDS is used to identify what the initiating event is, and can also give the information of safety system's status whether they are bypassed, inoperable or not. Initiating event and safety system's status are used in the construction of Containment Event Tree (CET) to determine containment failure modes by using probabilistic risk assessment (PRA) technique. Different initiating events will correspond to different CETs. With these CETs, the core melt frequency of an initiating event can be found. The use of Plant Damage States (PDS) is a symptom-oriented approach. On the other hand, the use of Containment Event Tree (CET) is an event-oriented approach. In this study, the Taiwan's fourth nuclear power plants, the Lungmen nuclear power station (LNPS), which is an advanced boiling water reactor (ABWR) with fully digitized instrumentation and control (I and C) system is chosen as the target plant. The LNPS full scope engineering simulator is used to generate the testing data for method development. The following common initiating events are considered in this study: loss of coolant accidents (LOCA), total loss of feedwater (TLOFW), loss of offsite power (LOOP), station blackout (SBO). Studies have indicated that the combination of the symptom-oriented approach and the event-oriented approach can be helpful to find mitigation strategies and is useful for the accident

    Full Text Available The automobile industry has grown to become an integral part of our everyday life. As vehicles evolve, the primarily mechanical solutions for vehicle control are gradually replaced by electronics and software solutions forming in-vehicle computer networks. An emerging trend is to introduce wireless technology in the vehicle domain by attaching a wireless gateway to the in-vehicle network. By allowing wireless communication, real-time information exchange between vehicles and between infrastructure and vehicles become reality. This communication allows for road condition reporting, decision making, and remote diagnostics and _rmware updates over-the-air. However, allowing external parties wireless access to the in-vehicle network creates a potential entry-point for cyber attackers. In this paper, we investigate the security issues of allowing external wireless communication. We use a defense-in-depth perspective and discuss security challenges and propose solutions for each of the prevention, detection, de_ection, and forensics approaches. We stress the important need for applying security using the defense-in-depth principle.

    The US industry, with the approval of the Nuclear Regulatory Commission, is promoting an approach to add diverse and flexible mitigation strategies, or Flex, that will increase the defense-in-depth capability for the nuclear power plants in the event of beyond design basis event, such as at the Fukushima Dai-ichi station. The objective of Flex is to establish and indefinite coping capability to prevent damage to the fuel in the core and spent fuel pool, and to maintain the containment function by utilizing installed equipment, on-site portable equipment and pre-staged off-site resources. This capability will address both an extended loss of all Ac power and a loss of ultimate heat sink which could arise following a design basis event with additional failures, and conditions from a beyond design basis event.

    This work developed an advanced boiling water reactor (ABWR) feedwater pump and controller model, which was incorporated into Personal Computer Transient Analyzer (PCTran)-ABWR, a nuclear power plant simulation code. The feedwater pump model includes three turbine-driven feedwater pumps and one motor-driven feedwater pump. The feedwater controller includes a one-element/three-element water level controller and a specific feedwater speed controller for each feedwater pump. The performance tests, including step change of dome pressure, feedwater pumps transfer, inadvertent closure of all turbine control valves, and one feedwater pump trip at 100% power, demonstrate the feasibility of dynamic response of stand-alone model and incorporated model. Furthermore, a diversity and defense-in-depth analysis is performed to demonstrate the feasibility for motor-driven feedwater pump as an emergency core cooling system (ECCS) automatic diverse back-up. In Lungmen nuclear power plant (NPP), a diverse manual initiation means for the high pressure core flooder (HPCF) loop C is designed as the back-up of digitalized engineered safety features actuation system (ESFAS). If the motor-driven feedwater pump (MDFWP) can be an automatic digital diverse back-up for ESFAS, Lungmen NPP would be more robust to defend against software common-cause failure (CCF)

    2003-01-01

    Social parasites exploit the socially managed resources of their host's society. Inquiline social parasites are dependent on their host throughout their life cycle, and so many of the traits inherited from their free-living ancestor are removed by natural selection. One trait that is commonly lost...... is the worker caste, the functions of which are adequately fulfilled by host workers. The few inquiline parasites that have retained a worker caste are thought to be at a transitional stage in the evolution of social parasitism, and their worker castes are considered vestigial and non-adaptive. However...... a vital role in ensuring the parasite's fitness. We show that the presence of these parasite workers has a positive effect on the production of parasite sexuals and a negative effect on the production of host sexuals. This suggests that inquiline workers play a vital role in suppressing host queen...

    Based on the definition of Defense-in-Depth levels and safety functions for KALIMER sodium-cooled fast reactor, suggested in the reference and, OPTs for level 1, 2, and 3 defense-in-depth and core heat removal safety function, were developed and suggested in this paper. The purpose of this OPT is first to assure the defensein-depth design during the licensing of Sodium-Cooled Fast Reactors (SFR), but it will also contribute in evaluating the completeness of regulatory requirements under development by Korea Institute of Nuclear Safety (KINS). The challenges and mechanisms and provisions were briefly explained in this paper. Comparing the mechanisms and provisions with the requirements will contribute in identifying the missing requirements. Since the design of PGSFR (Prototype Gen-IV SFR) is not mature yet, the OPT is developed for KALIMER design. Developed OPTs in this study can be used for the identification of potential design vulnerabilities. When detailed identification of provisions in terms of design features were achieved through the next step of this study, it can contribute to the establishment of defensein-depth evaluation frame for the regulatory reviews for the licensing process. At this moment, the identified provisions have both aspects as requirements and design features already adopted in KALIMER design. In the next stage of this study, derived provisions to be adopted will be compared with the actual design features and findings can be suggested as recommendations for the safety improvement.

    Digital instrumentation and control (I and C) systems are becoming an ever-increasing part in I and C systems of nuclear power plants due to such features such as versatility, flexibility, and reduced sizes. The digital technology introduces a possibility that common-cause or common-mode failures (CCF or CMF) may cause redundant safety systems to fail in such a way that there is loss of safety function. A special form of CMF analysis called 'defense-in-depth and diversity' (D-in-D and D) analysis has been developed to identify possible common-mode failure vulnerabilities and to support a specific licensing action in digital systems. There are two main stages in D-in-D and D activities: both plan and analysis. The purposes of this technical report are (i) to review background of D-in-D and D and some of important issues in digital D-in-D and D, (ii) to provide guidelines for a vendor to prepare planning and/or analysis documents on D-in-D and D, and (iii) to provide guidelines for an evaluator to review applicant's D-in-D and D planning and/or analysis documents, to ensure that the requirements of the D-in-D and D for digital I and C systems are followed. Most of guidelines suggested in this report were based on NUREG/CR-6303 which was published in 1994. The report will be helpful for a vendor to prepare and for an evaluator to review both D-in-D and D planning or analysis documents for digital I and C systems such as the KNGR project.

    Three hundred and fifteen female workers with at least three months' employment history in a factory manufacturing disk drives were studied. Each worker completed a self-administered questionnaire on their personal particulars, hours of work, opinion on the work and the workplace and the presence and severity of aches/pains experienced over the past one month. One hundred and forty one (44.8%) of the workers had complaints of aches/pains. Of these, 81 (57.5%) reported an improvement in their symptoms during their off-days. 59 (41.8%) had symptoms affecting two or more sites. The most commonly affected sites were the hands and shoulders, followed by the head and back. There was no significant difference in the prevalence of symptoms between workers from the different work stations. Ninety four (66.7%) of these workers reported that the pains that were severe enough to affect their activities. 76 (53.9%) had to seek some form of medical treatment while 33 (23.4%) had to be on medical leave. However, the physical examinations of this group of workers were normal. The symptoms appeared to be influenced by their attitude towards work. A significantly higher number of workers with symptoms expressed dissatisfaction with work and had complaints of a noisy and cold environment. The study showed that workers' morale and the quality of the work environment may play an important role in improving their general well-being.

    Although IgA is the most abundantly produced immunoglobulin in humans, its role in preventing HIV-1 acquisition, which occurs mostly via mucosal routes, remains unclear. In our passive mucosal immunizations of rhesus macaques (RMs), the anti-HIV-1 neutralizing monoclonal antibody (nmAb) HGN194, given either as dimeric IgA1 (dIgA1) or dIgA2 intrarectally (i.r.), protected 83% or 17% of the RMs against i.r. simian-human immunodeficiency virus (SHIV) challenge, respectively. Data from the RV144 trial implied that vaccine-induced plasma IgA counteracted the protective effector mechanisms of IgG1 with the same epitope specificity. We thus hypothesized that mucosal dIgA2 might diminish the protection provided by IgG1 mAbs targeting the same epitope. To test our hypothesis, we administered HGN194 IgG1 intravenously (i.v.) either alone or combined with i.r. HGN194 dIgA2. We enrolled SHIV-exposed, persistently aviremic RMs protected by previously administered nmAbs; RM anti-human IgG responses were undetectable. However, low-level SIV Gag-specific proliferative T-cell responses were found. These animals resemble HIV-exposed, uninfected humans, in which local and systemic cellular immune responses have been observed. HGN194 IgG1 and dIgA2 used alone and the combination of the two neutralized the challenge virus equally well in vitro. All RMs given only i.v. HGN194 IgG1 became infected. In contrast, all RMs given HGN194 IgG1+dIgA2 were completely protected against high-dose i.r. SHIV-1157ipEL-p challenge. These data imply that combining suboptimal defenses at the mucosal and systemic levels can completely prevent virus acquisition. Consequently, active vaccination should focus on defense-in-depth, a strategy that seeks to build up defensive fall-back positions well behind the fortified frontline.

    Full Text Available Objectives: Sense of coherence (SOC is an individual characteristic related to a positive life orientation, leading to effective coping. Little is known about the relationship between SOC and metabolic syndrome (MetS. This cross-sectional study aimed at testing the hypothesis that workers with a strong SOC have fewer atherosclerotic risk factors, including MetS, and healthier lifestyle behaviors. Material and Methods: One hundred and sixty-seven computer software workers aged 20–64 years underwent a periodical health examination including assessment of body mass index, waist circumference, blood pressure, blood lipid levels, fasting blood sugar (FBS levels and lifestyle behaviors (walking duration, smoking status, nutrition, alcohol consumption, and sleep duration. During this period, the participants also completed a 29-item questionnaire of SOC and the Brief Job Stress Questionnaire to assess job stressors such as job strain and workplace social support. Results: Our results showed that the participants with a stronger SOC were likely to walk for at least 1 h a day, to eat slowly or at a moderate speed, and to sleep for at least 6 h. Compared with the participants with the weakest SOC, those with the strongest SOC had a significantly lower odds ratio (OR for being overweight (OR = 0.31; 95% confidence interval (CI: 0.11–0.81, and having higher FBS levels (OR = 0.11; 95% CI: 0.02–0.54, dyslipidemia (OR = 0.29; 95% CI: 0.09–0.84, and MetS (OR = 0.12; 95% CI: 0.02–0.63, even after adjusting for age, gender and job stressors. Conclusions: High SOC is associated with a healthy lifestyle and fewer atherosclerotic risk factors, including MetS.

    The recent 1995 WIPP Safety Analysis Report (SAR) Update provided detailed analyses of potential radiation doses to members of the public at the site boundary during postulated accident scenarios at the U.S. Department of Energy`s Waste Isolation Pilot Plant (WIPP). The SAR Update addressed the complete spectrum of potential accidents associated with handling and emplacing transuranic waste at WIPP, including damage to waste drums from fires, punctures, drops, and other disruptions. The report focused on the adequacy of the multiple layers of safety practice ({open_quotes}defense-in-depth{close_quotes}) at WIPP, which are designed to (1) reduce the likelihood of accidents and (2) limit the consequences of those accidents. The safeguards which contribute to defense-in-depth at WIPP include a substantial array of inherent design features, engineered controls, and administrative procedures. The SAR Update confirmed that the defense-in-depth at WIPP is adequate to assure the protection of the public and environment. As a supplement to the 1995 SAR Update, we have conducted additional analyses to confirm that these controls will also provide adequate protection to workers at the WIPP. The approaches and results of the worker dose assessment are summarized here. In conformance with the guidance of DOE Standard 3009-94, we emphasize that use of these evaluation guidelines is not intended to imply that these numbers constitute acceptable limits for worker exposures under accident conditions. However, in conjunction with the extensive safety assessment in the 1995 SAR Update, these results indicate that the Carlsbad Area Office strategy for the assessment of hazards and accidents assures the protection of workers, members of the public, and the environment.

    Full Text Available The association of socioeconomic status (SES with nutrient intake attracts public attention worldwide. In the current study, we examined the associations of SES with dietary intake of folate and health outcomes in general Japanese workers. This Japanese occupational cohort consisted off 2266 workers. SES was assessed by a self-administered questionnaire. Intakes of all nutrients were assessed with a validated, brief and self-administered diet history questionnaire (BDHQ. The degree of depressive symptoms was measured by the validated Japanese version of the K6 scale. Multiple linear regression and stratified analysis were used to evaluate the associations of intake with the confounding factors. Path analysis was conducted to describe the impacts of intake on health outcomes. Education levels and household incomes were significantly associated with intake of folate and depression scales (p < 0.05. After adjusting for age, sex and total energy intake, years of education significantly affect the folate intake (β = 0.117, p < 0.001. The structural equation model (SEM shows that the indirect effect of folate intake is statistically significant and strong (p < 0.05, 56% of direct effect in the pathway of education level to depression scale. Our study shows both education and income are significantly associated with depression scales in Japanese workers, and the effort to increase the folate intake may alleviate the harms of social disparities on mental health.

    Information infrastructures across many public and private domains share several common attributes regarding IT deployments and data communications. This is particularly true in the control systems domain. A majority of the systems use robust architectures to enhance business and reduce costs by increasing the integration of external, business, and control system networks. However, multi-network integration strategies often lead to vulnerabilities that greatly reduce the security of an organization, and can expose mission-critical control systems to cyber threats. This document provides guidance and direction for developing ‘defense-in-depth’ strategies for organizations that use control system networks while maintaining a multi-tier information architecture that requires: • Maintenance of various field devices, telemetry collection, and/or industrial-level process systems • Access to facilities via remote data link or modem • Public facing services for customer or corporate operations • A robust business environment that requires connections among the control system domain, the external Internet, and other peer organizations.

    The C825T variant of the G-protein beta3 subunit (GNB3) gene has attracted renewed attention as a candidate gene for obesity, hypertension and hyperuricemia. The main role of G-protein is to translate signals from the cell surface into a cellular response. The 825T allele is associated with a splice variant of GNB3 protein and enhanced G-protein activation. We examined the relationship between this variant and the risk of hyperuricemia in Japanese workers. The study subjects were 1,452 men and 1,169 women selected from 3,834 men and 2,591 women in 1997. On the basis of common clinical criteria, hyperuricemia I was defined as serum uric acid >or= 7.0 mg/dl in men and 6.0 mg/dl in women or taking antihyperuricemic medication. The hyperuricemia I group consisted of 186 men and 20 women and its control of 1,266 men and 1,149 women. Hyperuricemia II was defined as serum uric acid > 5.7 mg/dl (median) in men and 3.9 mg/dl (median) in women or taking antihyperuricemic medication. The hyperuricemic II group consisted of 684 men and 570 women and its control of 768 men and 599 women. To replicate previous significant results in young Caucasian men, we selected these criteria because the authors of the study in young Caucasian men adopted the median in their subjects as a cut-off. The statistical power was estimated as 99% based on the significant results in Caucasians. Genotype and allele distributions in men and women with hyperuricemia I and II were not significantly different from those in the corresponding control groups. Logistic regression analysis on hyperuricemia I and II, and multiple regression on serum uric acid level demonstrated no significant effect of the C825T genotype. Despite the sufficient statistical power, this study could not demonstrate the significant influence of C825T on hyperuricemia or serum uric acid. The targeting of this polymorphism is unlikely to be beneficial in the prevention of hyperuricemia in the general Japanese population.

    Contingent workers compose a large portion of the U.S. work force. Contingent workers include temporary employees, contracted employees, day laborers, and freelancers. The skill level and educational requirements for their jobs vary from basic to highly advanced. Construction, housekeeping, engineering, and nursing have such positions. U.S. contingent workers are more likely to engage in occupations associated with increased risk of injury, and a variety of factors increase their risk of work injuries, particularly those leading to death. This article focuses on select occupational health and safety issues affecting contingent workers and their implications for occupational health nurses. Copyright 2011, SLACK Incorporated.

    About one person in eight remains employed past 65, the average age for retirement in the U.S. These persons tend to be highly reliable. They can adapt and learn new technology, but may require extra time to do so. Older workers have particular needs in the workplace due to physiological changes that accompany aging. They may require more lighting, and they may have decreased mobility, physical strength, and dexterity. These factors often have no impact on their ability to accomplish job duties. This chapter underscores the significant contributions that older workers often provide, and also addresses retirement planning.

    2015-01-01

    Full Text Available In recent years, the diffusion of mobile applications (mobile apps has risen significantly. Nowadays, mobile business apps are strongly emerging in business, enhancing productivity and employees’ satisfaction, whilst the usage of customized individual enterprise apps is still an exception. Standardized business apps enable basic functionalities, for example, mobile data storage and exchange (e.g., Dropbox, communication (e.g., Skype, and other routine processes, which support mobile workers. In addition, mobile apps can, for example, increase the flexibility of mobile workers by easing the access to firm’s information from outside the enterprise and by enabling ubiquitous collaboration. Hence, mobile apps can generate competitive advantages and can increase work efficiency on a broad scale. But mobile workers form no coherent group. Our research reveals, based on two case studies, that they can be clustered into two groups: knowledge workers and field workers. Knowledge workers and field workers fulfill different tasks and work in different environments. Hence, they have different requirements for mobile support. In this paper we conclude that standardized mobile business apps cannot meet the different requirements of various groups of mobile workers. Task- and firm-specific (individualized requirements determine the specification, implementation, and application of mobile apps.

    Hand dermatitis is common in workers in the horticultural industry. This study determined the prevalence of hand dermatitis in workers of Alstroemeria cultivation, investigated how many workers had been sensitized by tulipalin A (the allergen in Alstroemeria) and took stock of a wide range of determinants of hand dermatitis. The 12-month period prevalence of major hand dermatitis amounted to 29.5% whereas 7.4% had minor dermatitis. Of these workers, 52.1% were sensitized for tulipalin A. Several personal and work-related determinants played a role in the multifactorial aetiology of hand dermatitis. Factors which showed a significant relationship with major hand dermatitis were: female sex, atopic dermatitis, chapped hands and the frequency of washing hands. It may be concluded that the Alstroemeria workers are a population at risk of developing contact dermatitis and it might be useful to carry out an educational campaign to lower the high prevalence.

    The Former Hanford Worker Medical Monitoring Program, directed by the Occupational and Environmental Medicine Program at the University of Washington, served former production and other non-construction workers who were potentially exposed to workplace hazards while working for the USDOE or its contractors at Hanford. The USDOE Former Workers Program arose from Congressional action in the Defense Authorization of 1993 (Public Law 102). Section 3162 stated that, “The Secretary shall establish and carry out a program for the identification and ongoing medical evaluation of current and former Department of Energy employees who are subject to significant health risks as a result of exposure of such employees to hazardous or radioactive substances during such employment.” (This also covers former employees of USDOE contractors and subcontractors.) The key objective has been to provide these former workers with medical evaluations in order to determine whether workers have experienced significant risk due to workplace exposure to hazards. Exposures to asbestos, beryllium, and noise can produce specific medical conditions: asbestosis, berylliosis, and noise-induced hearing loss (NIHL). Each of these conditions can be identified by specific, non-invasive screening tests, which are widely available. Treatments are also available for individuals affected by these conditions. This project involved two phases. Phase I involved a needs and risk assessment, characterizing the nature and extent of workplace health hazards which may have increased the risk for long-term health effects. We categorized jobs and tasks by likelihood of exposures to specific workplace health hazards; and located and established contact with former Hanford workers. Phase II involved implementation of medical monitoring programs for former workers whose individual work history indicated significant risk for adverse health effects. We identified 118,000 former workers, employed from 1943 to 1997

    Cross-sectional questionnaire data were used to compare the levels of job strain in shift and daytime workers. Job strain was measured according to Karasek's Demands/Discretion model. Four occupational groups were included: drivers, industrial workers, policemen/watchmen, and cooks. The study subjects were a random sample of 508 daytime workers and 418 shift workers. Job demand did not differentiate between shift and daytime workers, comparing groups broken down by gender and by occupation. The daytime workers reported higher levels of job strain than the shift workers, and women experienced a higher level of job strain than did men. Multiple linear regression analysis showed that only occupational group and gender predicted job strain level. Shiftwork was not significantly associated with job strain in the regression model.

    2012-01-01

    Full Text Available While there have been a variety of studies concerning government worker motivation and productivity, few, if any, studies have focused specifically on state government workers’ perceptions about what factors affect their productivity. With more than 5 million workers employed by state governments in the United States, any improvement in state workplace productivity could have significant financial and service impact for society. In this study, state government workers identified those factors perceived as most affecting their workplace productivity. Data were collected through a survey offered to state government workers in the state of Wyoming. Factor analysis was used to derive key productivity factors from survey responses. The results indicate that state government workers appreciate having freedom and autonomy, like their jobs and the sense of achievement, and welcome teamwork, but feel limited by poor supervision and management, poor communications, and insufficient budgets and staffing. To improve productivity, the workers would eliminate bureaucracy, supervise better, and improve communication.

    Objective. This research was guided by a stress and support model to examine the effects of frontline workers' background characteristics, personal stressors, job-related stressors, and workplace support on satisfaction with supervision. Method. Survey data were collected from 644 workers in 49 long-term-care settings that employed them. Regression analysis were used to determine the effects of worker level and then Hierarchical Linear Modeling (HLM) and organizational factors on the outcome. Results. Although all four variable categories made significant contributions to explaining satisfaction with supervision, the most powerful were personal stressors and job-related stressors. Results from HLM analysis showed frontline workers in nursing homes and those employed in for-profit organizations had lower levels of satisfaction with supervision. Discussion. Findings suggest organizational interventions to address workers' financial and health issues and management practices such as better training programs and peer mentoring could enhance workers' satisfaction with supervision.

    Full Text Available The most common hazards in the forestry that may induce disorders of the musculoskeletal system are vibrations, unfavorable microclimatic conditions, noise, over-time working hours, work load and long-term repeated movements. The objective of this study was to analyze the prevalence of musculoskeletal diseases and its difference among workers engaged in various jobs in the forestry. Two groups of workers were selected: woodcutters operating with chain-saw (N=33 and other loggers (N=32. Selected workers were of the similar age and had similar total length of employment as well as the length of service in the forestry. Both groups of workers employed in the forestry had the high prevalence of musculoskeletal diseases (woodcutters 69.7% and other loggers 62.5%, respectively. Degenerative diseases of spinal column were very frequent, in dependently of the type of activity in the forestry. Non-significantly higher risk of carpal tunnel syndrome was found in woodcutters with chain-saw compared to workers having other jobs in the forestry (OR=3.09; 95%CI=0.64-19.72. The lateral epicondylitis was found only in woodcutters operating with chain-saw with the prevalence of 18.2%.

    Background: In this study, the characteristics of menstrual cycle in shift workers employed in the pharmaceutical industry are investigated. Method: This study was conducted in a pharmaceutical industrial complex in Tehran in 2012. 406 female workers in packaging units were studied on the menstrual cycle characteristics. The studied workers were divided into two groups of shift workers and non-shift workers and were compared in terms of the frequency of menstrual disorder (short-term cycle, long-term cycle, irregular cycle and bleeding during menstrual cycle) as well as hormonal values (FSH, LH, TSH, and Prolactin). Results: The odds ratio (OR) for menstrual disorder in the shift workers was 5.54 (95% CI=2.78-11.02) compared to the non-shift workers. The mean difference of hormonal values (except prolactin) between shift workers and non-shift workers was not significant (P> 0.05). Conclusion: This study suggests that shift work may disrupt the menstrual cycle. PMID:23618486

However,  it is acommon practice that most of the workers still ignored the importance of the use of noise reduction devices suchas earmuff or ear plug.  This study was aimed to reveal the factual effects of noise on work concentration of theworkers to provide a scientific basis in supporting efforts in improving workers’ attitude.  The results confirmedthat chainsaw might produce noise during operation.  Noise intensities received by both right and left ears werenot significantly different, indicating that left-handed and normal workers received similar degree of noise inboth side of ears. Further, results also showed that there was a significant difference on the perception and workconcentration of chainsaw operators versus sedentary people to the noise.  These findings proved that hearingability of chainsaw operators had declined due to frequent noise exposure.Keywords: timber harvesting, physio-psychological disorder, noise, chainsaw

    The aim of this study was to establish and identify the health effect markers of workers with potential exposure to nanoparticles (20-100 nm) during manufacturing and/or application of nanomaterials. For this cross-sectional study, we recruited 227 workers who handled nanomaterials and 137 workers for comparison who did not from 14 plants in Taiwan. A questionnaire was used to collect data on exposure status, demographics, and potential confounders. The health effect markers were measured in the medical laboratory. Control banding from the Nanotool Risk Level Matrix was used to categorize the exposure risk levels of the workers. The results showed that the antioxidant enzyme, superoxide dismutase (SOD) in risk level 1 (RL1) and risk level 2 (RL2) workers was significantly (p < 0.05) lower than in control workers. A significantly decreasing gradient was found for SOD (control > RL1 > RL2). Another antioxidant, glutathione peroxidase (GPX), was significantly lower only in RL1 workers than in the control workers. The cardiovascular markers, fibrinogen and ICAM (intercellular adhesion molecule), were significantly higher in RL2 workers than in controls and a significant dose-response with an increasing trend was found for these two cardiovascular markers. Another cardiovascular marker, interleukin-6, was significantly increased among RL1 workers, but not among RL2 workers. The accuracy rate for remembering 7-digits and reciting them backwards was significantly lower in RL2 workers (OR = 0.48) than in controls and a significantly reversed gradient was also found for the correct rate of backward memory (OR = 0.90 for RL1, OR = 0.48 for RL2, p < 0.05 in test for trend). Depression of antioxidant enzymes and increased expression of cardiovascular markers were found among workers handling nanomaterials. Antioxidant enzymes, such as SOD and GPX, and cardiovascular markers, such as fibrinogen, ICAM, and interluekin-6, are possible biomarkers for medical surveillance of

    the design, OSS was able to develop and successfully test, in both the lab and in the field, a prototype AWPS. They clearly demonstrated that a system which provides cooling can significantly increase worker productivity by extending the time they can function in a protective garment. They were also able to develop mature outer garment and LCG designs that provide considerable benefits over current protective equipment, such as self donning and doffing, better visibility, and machine washable. A thorough discussion of the activities performed during Phase 1 and Phase 2 is presented in the AWPS Final Report. The report also describes the current system design, outlines the steps needed to certify the AWPS, discusses the technical and programmatic issues that prevented the system from being certified, and presents conclusions and recommendations based upon the seven year effort.

    Full Text Available The study of the motivation of construction workers is limited to a relatively small body of knowledge. Although there is considerable research available regarding motivation and productivity, few researchers have provided a comprehensive analysis on the motivation of construction workers. The research stated that productivity in construction has not improved compared to other industry sectors such as manufacturing. This trend has been echoed in publications throughout the past five decades, and suggested that motivation is one of the key factors impacting productivity. This paper offers a comprehensive review of the published work that directly links the key words—construction and motivation. The findings have been presented in five themes, that is, motivation models, environment and culture, incentives and empowerment, and worker management. This paper concludes with two methods suggested by previous researchers to improve motivation of construction workers: (1 relevant worker incentives (intrinsic or extrinsic and (2 improved management practices, specifically regarding communication with workers.

    Eryptosis is a physiological phenomenon in which old and damaged erythrocytes are removed from circulation. Erythrocytes incubated with lead have exhibited major eryptosis. In the present work we found evidence of high levels of eryptosis in lead exposed workers possibly via oxidation. Blood samples were taken from 40 male workers exposed to lead (mean blood lead concentration 64.8 μg/dl) and non-exposed workers (4.2 μg/dl). The exposure to lead produced an intoxication characterized by 88.3% less δ-aminolevulinic acid dehydratase (δALAD) activity in lead exposed workers with respect to non-lead exposed workers. An increment of oxidation in lead exposed workers was characterized by 2.4 times higher thiobarbituric acid-reactive substance (TBARS) concentration and 32.8% lower reduced/oxidized glutathione (GSH/GSSG) ratio. Oxidative stress in erythrocytes of lead exposed workers is expressed in 192% higher free calcium concentration [Ca{sup 2+}]{sub i} and 1.6 times higher μ-calpain activity with respect to non-lead exposed workers. The adenosine triphosphate (ATP) concentration was not significantly different between the two worker groups. No externalization of phosphatidylserine (PS) was found in non-lead exposed workers (< 0.1%), but lead exposed workers showed 2.82% externalization. Lead intoxication induces eryptosis possibly through a molecular pathway that includes oxidation, depletion of reduced glutathione (GSH), increment of [Ca{sup 2+}], μ-calpain activation and externalization of PS in erythrocytes. Identifying molecular signals that induce eryptosis in lead intoxication is necessary to understand its physiopathology and chronic complications. - Graphical abstract: Fig. 1.

    Full Text Available Background: Occupational exposure to cotton dust, fibers, metal fumes and different chemicals used in the apparel manufacturing industries cause a wide range of physical and psychological health problems in the garment workers that may also affect their immune function.Objective: To assess the immune system function in garment workers.Methods: A total of 45 workers of a garment factory, and 41 control subjects, not exposed to the garment working environment were enrolled in this study. In the study subjects, the complement system function was assessed as bactericidal activity on Escherichia coli DH5α cells using the standard plate count method. Serum complement components C3 and C4 were measured by immunoprecipitation, and IgG was measured by immunonephelometry.Results: The bactericidal activity of serum complement in the garment workers (range: 93.5%–99.9% was significantly (p<0.01 lower than that in the controls (range: 98.6%–100%. The heat-inactivated serum of the workers showed a significantly enhanced bactericidal activity. In the garment workers, the mean levels of complement C3, and C4 were 1.75 and 0.26 g/L, respectively that were close to those of the controls. The mean IgG level in the garment workers was 13.5 g/L that was significantly (p<0.001 higher than that in the controls. Conclusion: Working in a garment factory may affect the immune system.

  5. Mortality among rubber workers: V. processing workers.

    Delzell, E; Monson, R R

    1982-07-01

    Cause-specific mortality was evaluated among 2,666 men employed in the processing division of a rubber manufacturing plant. The division was divided into two sections: front processing (compounding, mixing and milling operations) and back processing (extrusion, calendering, cement mixing and rubberized fabrics operations). Mortality rates for all processing workers combined and for men in each section were compared with rates for U.S. White males or for workers employed in other divisions of the same plant. Compared with either referent group, men in the processing division had increased mortality from leukemia, emphysema, and cancers of the stomach, large intestine, and biliary passages and liver. An excess number of deaths from stomach and larger intestine cancer was found predominantly among men in the front processing section (33 observed vs. 17.7 expected deaths, based on rates in nonprocessing workers). Increased mortality from leukemia (14 observed vs. 7.3 expected) and from emphysema (22 observed vs. 11.0 expected) was present among men employed in the back processing section. Examination of mortality from these causes according to age and the year starting work, duration of employment, and years since starting work in the relevant sections of the processing division suggested that observed excesses of stomach cancer, large intestine cancer, leukemia, and emphysema among processing workers are related to occupational exposures. These results are consistent with the findings of studies of other groups of rubber workers.

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D&D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D&D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D&D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project will result in the development of an Advanced Worker Protection System (AWPS). The AWPS will be built around a life support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack will be combined with advanced protective garments, advanced liquid cooling garment, respirator, communications, and support equipment to provide improved worker protection, simplified system maintenance, and dramatically improve worker productivity through longer duration work cycles. Phase I of the project has resulted in a full scale prototype Advanced Worker Protection Ensemble (AWPE, everything the worker will wear), with sub-scale support equipment, suitable for integrated testing and preliminary evaluation. Phase II will culminate in a full scale, certified, pre-production AWPS and a site demonstration.

    Full Text Available Motivation is one of the most important factors influencing workers' productivity. An increase in workers' motivation could add more value to organizations' structure and influence the profitability, significantly. In this paper, we study different factors on demotivating workers using questionnaire consist of various questions. The questionnaire is distributed among some employees who work for rubber production units located in Esfahan, Iran. The results of this survey indicate that discrimination on annual job compensation, entrusting responsibilities and unpleasant relationship with family partner are some of the most important factors influencing employees' motivation. While financial factors play important role on increasing employees' motivation, non-financial factors are considered more important.

    Mieke Koehoorn

    Full Text Available To investigate the feasibility, costs and sample representativeness of a recruitment method that used workers with back injuries as the point of entry into diverse working environments.Workers' compensation claims were used to randomly sample workers from five heavy industries and to recruit their employers for ergonomic assessments of the injured worker and up to 2 co-workers.The final study sample included 54 workers from the workers' compensation registry and 72 co-workers. This sample of 126 workers was based on an initial random sample of 822 workers with a compensation claim, or a ratio of 1 recruited worker to approximately 7 sampled workers. The average recruitment cost was CND$262/injured worker and CND$240/participating worksite including co-workers. The sample was representative of the heavy industry workforce, and was successful in recruiting the self-employed (8.2%, workers from small employers (<20 workers, 38.7%, and workers from diverse working environments (49 worksites, 29 worksite types, and 51 occupations.The recruitment rate was low but the cost per participant reasonable and the sample representative of workers in small worksites. Small worksites represent a significant portion of the workforce but are typically underrepresented in occupational research despite having distinct working conditions, exposures and health risks worthy of investigation.

    The potential cytogenetic damage in offset printing workers was evaluated using sister chromatid exchanges (SCEs), chromosome aberrations (CAs) and micronuclei (MN) as biomarkers in peripheral lymphocytes of 26 volunteers (14 workers, 12 controls). The CA, SCE and MN frequency of offset printing workers was significantly higher than in their controls. The replication index (RI) was not affected while the mitotic index (MI) was affected most in the workers. It can be concluded from this study that chronic occupational exposure to printing dyes and thinner may lead to a slightly increased risk of genetic damage among offset printing workers.

    Night and shift work might be risk factors for metabolic and cardiovascular disorders due to interference with diet, circadian metabolic rhythms, and lifestyle. The relationship between permanent night work and metabolic and cardiovascular risk factors was explored in a retrospective longitudinal study of workers employed in a large municipal enterprise in charge of street cleaning and domestic waste collection. All subjects who had worked night shifts between 1976 and 2007 as hand sweepers, motor sweepers, and delivery tricar drivers were compared with subjects who always worked the same jobs but on day shifts. From the periodical medical surveillance files, we identified 488 male workers who had been examined on average five times (minimum 2, maximum 14) during the study period, for a total of 2,328 medical examinations; 157 always had worked day shifts, 12 always the night shift, and 319 both (initially day and subsequently night shifts). Their age ranged from 22 to 62 yrs, and work experience varied from 1 to 28 yrs. Lifestyle habits (smoking, alcohol consumption), body mass index, serum glucose, total cholesterol, tryglicerides, hepatic enzymes, blood pressure, resting electrocardiogram, diabetes, coronary heart disease, hypertension, and related drugs were taken into consideration for the analysis. We used generalized estimating equations (GEE) models (exchangeable correlation matrix) to analyze the relationship between night work and health effects while accounting for within-subject correlations and adjusting for study period, job, age, and lifestyle variables. As a whole, night workers smoked more and had significantly higher BMI, serum total cholesterol, and triglycerides than day workers. Both the inter-individual comparison between day and night workers and the intra-individual comparison among the workers, who were day workers at the beginning of their employment and later became night workers, showed a significant increase in BMI, total cholesterol

  16. [Indian workers in Oman].

    Longuenesse, E

    1985-01-01

    Until recently Oman was a country of emigration, but by 1980 an estimated 200,000 foreign workers were in the country due to the petroleum boom. Almost 1/3 of the estimated 300,000 Indian workers in the Gulf states were in Oman, a country whose colonial heritage was closely tied to that of India and many of whose inhabitants still speak Urdu. The number of work permits granted to Indians working in the private sector in Oman increased from 47,928 in 1976 to 80,787 in 1980. An estimated 110,000 Indians were working in Oman in 1982, the great majority in the construction and public works sector. A few hundred Indian women were employed by the government of Oman, as domestics, or in other capacities. No accurate data is available on the qualifications of Indian workers in Oman, but a 1979 survey suggested a relatively low illiteracy rate among them. 60-75% of Indians in Oman are from the state of Kerala, followed by workers from the Punjab and the southern states of Tamil Nadu and Andhra Pradesh and Bombay. Indian workers are recruited by specialized agencies or by friends or relatives already employed in Oman. Employers in Oman prefer to recruit through agencies because the preselection process minimizes hiring of workers unqualified for their posts. Officially, expenses of transportation, visas, and other needs are shared by the worker and the employer, but the demand for jobs is so strong that the workers are obliged to pay commissions which amount to considerable sums for stable and well paying jobs. Wages in Oman are however 2 to 5 times the level in India. Numerous abuses have been reported in recruitment practices and in failure of employers in Oman to pay the promised wages, but Indian workers have little recourse. At the same level of qualifications, Indians are paid less then non-Omani Arabs, who in turn receive less than Oman nationals. Indians who remain in Oman long enough nevertheless are able to support families at home and to accumulate considerable

    Although known neurotoxins with potential ophthalmotoxic properties are commonly used in microelectronics assembly, there has been no systematic study of visual disturbances among past or present workers in this industry. The objective of the present study was to compare visual functions, using a matched-pair design, between former workers from a microelectronics plant and a local reference population. From an initial population of 180 former workers and 157 potential referents, 54 pairs were matched for age (+/- 3 y), education (+/- 2 y), sex, ethnic origin, and number of children. Near and far visual acuity, chromatic discrimination, and near contrast sensitivity were assessed monocularly. Paired comparisons (Signed-rank Wilcoxon test) revealed that the former microelectronics workers had significantly lower contrast sensitivity, particularly in the intermediate frequencies, independently of near visual acuity loss. There were no differences for far visual acuity in both eyes. Even though near visual acuity and color vision were compromised among the former workers, the differences were only significant for one eye, as was the prevalence of acquired dyschromatopsia (chi-square for matched pairs, p less than .001). These findings suggest a pattern of contrast sensitivity deficits consistent with impairment to foveal and/or neuro-optic pathways among these former microelectronics workers. Exposure to ophthalmotoxic chemicals is proposed as the most probable risk factor.

    Although chemicals posing potential neurotoxic hazards are commonly used in the microelectronics industry, there has been no systematic study of possible chronic nervous system effects in microelectronics workers. The objective of the present study was to assess neuropsychological functions of a group of former microelectronics plant assembly workers and a group of referents, using a matched pair design. During employment, the former microelectronics workers had been exposed to multiple organic solvents, including trichloroethylene, xylene, chlorofluorocarbons and trichloroethane. Referents were recruited from the same geographic region. From a pool of 180 former workers and 157 referents, 67 pairs were matched on the basis of age, sex, ethnicity, educational level, sex and number of children. Comparison of results on the subtests of the California Neuropsychological Screening Battery-Revised (CNS-R) revealed significantly lower performance by the former microelectronics workers on tests of attention/concentration, verbal ability, memory functions, visuospatial functions, visuomotor speed, cognitive flexibility, psychomotor speed, and reaction time (t-test for pairs or Wilcoxon Signed Rank p less than 0.05). No significant differences were observed for performance on tests assessing mental status, visual recall, tactile function and learning. This overall pattern of impairment is consistent with organic solvent-related chronic toxic encephalopathy, and possible early stages of dementia. These findings underline the need for more studies among workers currently or previously employed in microelectronics industries.

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D&D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D&D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D&D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project describes the development of an Advanced Worker Protection System (AWPS) which will include a life-support backpack with liquid air for cooling and as a supply of breathing gas, protective clothing, respirators, communications, and support equipment.

    2009-04-01

    This study investigates how job insecurity and employability relate to job satisfaction and affective organizational commitment in permanent workers, fixed-term contract workers, and temporary agency workers. The authors hypothesized that (a) job insecurity relates negatively to job satisfaction and affective organizational commitment, and this relationship is strongest in permanent workers and weakest in temporary agency workers; and that (b) employability relates positively to job satisfaction and negatively to affective organizational commitment, and this relationship is strongest in temporary agency workers and weakest in permanent workers. Hypotheses were tested in workers (permanent: n = 329; fixed term; n = 160; temporary agency: n = 89) from 23 Belgian organizations. The results show that job insecurity related negatively to the outcomes for permanent workers and temporary agency workers. This relationship was not significant for fixed-term contract workers. Employability related negatively to the outcomes for fixed-term contract workers and temporary agency workers, and this relationship was not significant for permanent workers. The 3 groups had different interpretations of what constitutes a stressor and about what signals a good employment relationship.

    To assess lead exposure in the Jamaican lead-acid battery industry, we surveyed three battery manufacturers (including 46 production workers) and 10 battery repair shops (including 23 battery repair workers). Engineering controls and respiratory protection were judged to be inadequate at battery manufacturers and battery repair shops. At manufacturers, 38 of 42 air samples for lead exceeded a work-shift time-weighted average concentration of 0.050 mg/m3 (range 0.030-5.3 mg/m3), and nine samples exceeded 0.50 mg/m3. Only one of seven air samples at repair shops exceeded 0.050 mg/m3 (range 0.003-0.066 mg/m3). Repair shop workers, however, had higher blood lead levels than manufacturing workers (65% vs. 28% with blood lead levels above 60 micrograms/dl, respectively). Manufacturing workers had a higher prevalence of safe hygienic practices and a recent interval of minimal production had occurred at one of the battery manufacturers. Workers with blood lead levels above 60 micrograms/dl tended to have higher prevalences of most symptoms of lead toxicity than did workers with lower blood lead levels, but this finding was not consistent or statistically significant. The relationship between zinc protoporphyrin concentrations and increasing blood lead concentrations was consistent with that described among workers in developed countries. The high risk of lead toxicity among Jamaican battery workers is consistent with studies of battery workers in other developing countries.

  9. Job and life satisfaction of nonstandard workers in South Korea.

    Since the South Korean financial crisis of the late 1990s, the number of nonstandard workers in South Korea has increased rapidly. With such a drastic change, it has been difficult to establish national welfare systems (e.g., accident insurance or support for families with dependent children) for nonstandard workers and identify critical aspects of their health. To evaluate job and life satisfaction among nonstandard workers, this study used a representative sample of South Koreans. Using data from the 2008 Korean Labor and Income Panel Study, the sample size totaled 4,340 observations, of which 1,344 (31.0%) involved nonstandard workers. Significant differences in job and life satisfaction between nonstandard workers and standard workers were found. The results also indicate discrimination in the welfare and fringe benefit systems in South Korea. Occupational health nurses must address the physical and psychological health issues, personal problems, and everyday life concerns of nonstandard workers. Given that the employment status of nonstandard workers in companies is generally unstable, it is difficult for these workers to report poor working conditions to employers or other authorities. Accordingly, occupational health nurses should advocate for nonstandard workers by notifying employers of the many problems they face.

    Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

    Because of reports linking an increased risk of leukemia with exposure to ethylene oxide, a mortality study of workers with potential exposure to ethylene oxide at the Texaco Chemical Company Plant in Port Neches, Tex., was undertaken. A total of 767 males with potential exposure to ethylene oxide were identified. Forty-six deaths occurred in this cohort with 80 expected (standardized mortality ratio; SMR = 58). No deaths from leukemia were seen, nor were there any statistically significant excesses from any specific causes of death.

    Workers in insect societies are sometimes observed to kill male eggs of other workers, a phenomenon known as worker policing. We perform a mathematical analysis of the evolutionary dynamics of policing. We investigate the selective forces behind policing for both dominant and recessive mutations for different numbers of matings of the queen. The traditional, relatedness-based argument suggests that policing evolves if the queen mates with more than two males, but does not evolve if the queen mates with a single male. We derive precise conditions for the invasion and stability of policing alleles. We find that the relatedness-based argument is not robust with respect to small changes in colony efficiency caused by policing. We also calculate evolutionarily singular strategies and determine when they are evolutionarily stable. We use a population genetics approach that applies to dominant or recessive mutations of any effect size. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2008-01-01

    The discussion and debate stimulated by these papers focused across a range of issues but there were four main areas of questioning: "measuring" and monitoring migration (issues related to comparability, completeness and accuracy of data sets on human resources); the impact of migration of health workers on health systems; the motivations of individual health workers to migrate (the "push" and "pull" factors) and the effect of policies designed either to reduce migration (e.g "self ufficiency") or to stimulate it (e.g active international recruitment). It was recognised that there was a critical need to examine migratory flows within the broader context of all health care labour market dynamics within a country, that increasing migration of health workers was an inevitable consequence of globalisation, and that there was a critical need to improve monitoring so as to better inform policy formulation and policy testing in this area.

    1988-01-01

    Telangiectases were detected in 57 (46.7%) of 122 workers employed at the electrolysis department of the aluminium plant Lozovac/Sibenik, Yugoslavia. Of 116 workers employed in the smeltery of the same plant, telangiectases were observed in 19 persons (16.4%) and in a group of 121 public transportation workers from Sibenik 15 men (12.4%) displayed enlarged blood vessels. Statistical evaluation revealed the difference in number between workers showing telangiectases engaged in electrolysis and the other two samples to be significant. It may be assumed that telangiectases were caused by hydrogen fluoride and other fluorides. Further clinical parameters, as well as working conditions, are reviewed.

    Entrepreneurial behavior of returning migrant workers plays a significant role in development of rural areas. Management of entrepreneurial environment can stimulate enthusiasm of migrant workers for entrepreneurial activities,reducing their entrepreneurial costs,and increasing the probability of their success in entrepreneurial activities. Management of entrepreneurial environment includes management of financing,system,technology,and social network environment. It is recommended to improve fitting and mutual adaptation of different types of environment through consolidating various types of environment,and make overall environment management from the entrepreneurial process of migrant workers,so as to improve enthusiasm of migrant workers for entrepreneurial activities and increase the probability of successful entrepreneurial activities.

    1985-02-01

    The results of health questionnaire interviews with 390 electrical power transmission and distribution workers, together with long term estimates of their exposure to 50 Hz electric fields, and short term measurements of the actual exposure for 287 of them are reported. Twenty eight workers received measurable exposures, averaging about 30 kVm-1h over the two week measurement period. Estimated exposure rates were considerably greater, but showed fair correlation with the measurements. Although the general level of health was higher than we have found in manual workers in other industries, there were significant differences in the health measures between different categories of job, different parts of the country, and in association with factors such as overtime, working alone, or frequently changing shift. After allowing for the effects of job and location, however, we found no significant correlations of health with either measured or estimated exposure to electric fields.

    Kawachi, Ichiro

    2008-10-01

    The global integration of economies worldwide has led to increased pressure for "labor flexibility". A notable aspect of this trend has been the rise in non-standard work arrangements, which include part-time work, temporary agency-based work, fixed-term contingent work, and independent contracting. Although non-standard work arrangements are convenient for employers, they are often associated with poor pay, absence of pension and health benefits, as well as lack of protection from unions and labor laws. Studies have begun to address the question of whether these "precarious" jobs pose a health hazard for workers. The challenge for causal inference is that precarious workers are likely to differ from non-precarious workers in a variety of characteristics that also influence health outcomes, i.e. there is confounding and selection bias. However, even after taking account of these biases--through propensity score-matched analysis--there is evidence to suggest that non-standard work may be damaging to workers' health. Policies modeled after the European Union's Directive on Part-Time Work may help to mitigate some of the health hazards associated with precarious work.

    Full Text Available The purpose of this study is to examine perception of inequality and types of reaction of white and blue collar workers. The research was conducted over 120 white collar and 159 blue collar workers in an academic institution. It was determined with correlation analysis whether there is a relation between perception of inequality and reaction towards it for two groups. A significant and positive relation has been found between inequality perceptions and reaction towards inequality of blue collar workers. No significant relation has been found for white collar workers. Factor analysis was used to determine the dimensions of inequality perceptions andreactions towards inequality of blue and white collar workers. Results show that inequality perceptions and types of reactions towards inequality differ in terms of dimensions. Equity perceptions of blue collar workers are mostly based on comparisons with colleagues and nepotist behavior of their managers. White collar workers show sensitivity to the issues like salary, promotion and status. Blue collar workers prefer to report or to persuade their managers when they face with inequality. White collar workers decide to show their reactions by using more political methods.

    Full Text Available Abstract Background Restless Legs Syndrome (RLS is a common neurological movement disorder characterized by symptoms that follow a circadian pattern. Night and rotating shift work schedules exert adverse effects on functions of the human body by disturbing circadian rhythms, and they are known to cause sleep disturbances and insomnia. In this paper, we investigate the possible association between shift work and RLS. Methods This cross sectional study was conducted in an automobile manufacturing factory in Tehran, Iran. A total of 780 male assembly workers were recruited in three groups, each with 260 workers: workers on a permanent morning shift (A and two different rotating shift schedules (B and C with morning, afternoon and night shifts. We used the international RLS study group criteria for diagnosis of RLS, and the severity scale for severity assessment in subjects with RLS. Self administered questionnaires were used to gather information on age, smoking, work history, medical condition, and existence and severity of RLS symptoms. Results The prevalence of RLS was significantly higher in rotational shift workers (15% than workers with permanent morning work schedule (8.5%. In workers suffering from RLS, we found greater mean values of age and work experience, higher percentages of drug consumption, smoking, and co-morbid illnesses compared with subjects who did not have RLS, although these differences were statistically significant only for age, work experience and drug consumption. Conclusion Rotational shift work acts as a risk or exacerbating factor for Restless Legs Syndrome.

    Full Text Available Background and Design: We aimed to determine the frequency of latex allergy in our hospital and to to evaluate the clinical and demographical features of the cases.Materials and Methods: A detailed questionnaire was administered to healthcare workers by a physician. Skin prick test with latex and patch test with rubber chemicals and a piece of latex glove were performed for all healthcare workers. Latex-specific IgE was measured in serum.Results: The study sample consisted of 36 nurses, 14 doctors, and 50 healthcare workers. While 46 subjects had symptoms, 54 subjects had no symptoms. The relationship of clinical disease with working duration, exposure duration (hour/day, history of atopy, and drug/food allergies was statistically significant. Five nurses and 1 healthcare worker had positive skin prick test. Two of them had positive latex-specific IgE. Positive skin prick test statistically significantly correlated with occupation, working duration, exposure duration (hour/day and positive latex-specific IgE. Two nurses and 2 healthcare workers had positive latex-specific IgE. Two of them had positive skin prick test. Positive latexspecific IgE statistically significantly correlated with working duration, exposure duration, and positive skin prick test. Patch test with a piece of latex glove was negative in all subjects. Three healthcare workers had positive patch test with thiuram-mix, one of them had also positive patch test with mercaptobenzothiazole.Discussion: One of the risk factors for latex allergy is occupations involving frequent exposure to latex products. Latex allergy should be taken into consideration if type I hypersensitivity reactions occur in occupational groups at risk for anaphylactic reaction.

    Full Text Available Objective: To assess cataract incidence in the cohort of workers occupationally exposed to prolonged radiation. Material and Methods: Cataract incidence was studied in the cohort of workers of the first Russian nuclear enterprise — the Mayak, who were firstly employed at one of the main facilities (reactors, radiochemical and plutonium production plants in 1948‑1958 and followed up to the end of 2008 (12210 persons. Total of 3100 cataract cases were registered in the study cohort. All cataract cases were reviewed and verified by experts; the study included only confirmed senile cataracts. All workers of the study cohort were exposed to external gamma-rays; mean cumulative dose from external gamma-rays was 0.91±0.01 Gy in males and 0.65±0.01 Gy in females. Statistical analysis provided non-standardized and standardized incidence rates per 100 000 workers. Standardization by sex and age was performed by indirect method using internal reference.Results: 2523 cases of senile cataract were included in the study. Mean age of cataract diagnosis was 62.88±0.26 years in males and 64.88±0.28 years in females. Standardized incidence rates of cataract in females were significantly higher as compared to males and increased with workers age. Comparison between the subcohorts of workers with / without diagnosed cataracts demonstrated that among workers with cataracts the proportions of the following groups of workers were significantly higher: workers employed before 1954; workers employed at reactors; smoking workers; workers with the smoking index exceeding 20 pack*years; workers who consumed alcohol; workers with excessive body weight; workers with glaucoma and arterial hypertension. Moreover the mean cumulative dose from external gamma-rays and / or neutron exposure was significantly higher in the subcohort of workers diagnosed with cataracts than that in the subcohort of workers free of the disease. The highest cataract incidence

    Full Text Available Abstract Background From animal studies it is known that currently used pesticides can disturb thyroid function. Methods In the present study we investigated the thyroid function in 122 Danish greenhouse workers, to evaluate if greenhouse workers classified as highly exposed to pesticides experiences altered thyroid levels compared to greenhouse workers with lower exposure. Serum samples from the greenhouse workers were sampled both in the spring and the fall to evaluate if differences in pesticide use between seasons resulted in altered thyroid hormone levels. Results We found a moderate reduction of free thyroxine (FT4 (10–16% among the persons working in greenhouses with a high spraying load both in samples collected in the spring and the fall, but none of the other measured thyroid hormones differed significantly between exposure groups in the cross-sectional comparisons. However, in longitudinal analysis of the individual thyroid hormone level between the spring and the fall, more pronounced differences where found with on average 32% higher thyroid stimulating hormone (TSH level in the spring compared to the fall and at the same time a 5–9% lower total triiodthyroxin (TT3, free triiodthyroxine (FT3 and FT4. The difference between seasons was not consistently more pronounced in the group classified as high exposure compared to the low exposure groups. Conclusion The present study indicates that pesticide exposure among Danish greenhouse workers results in only minor disturbances of thyroid hormone levels.

    Full Text Available Background: Long term occupational exposure to cotton dust is associated with respiratory symptoms and loss of pulmonary function. Aim: This study was conducted to explore respiratory symptoms, pulmonary function tests and chest radiography of workers, and to evaluate the findings of high resolution computed tomographyand its correlation with pulmonary function tests (PFT. Material and Methods: The study was conducted on 100 cotton workers as exposed group and 100 unexposed subjects. Smokers were excluded from the study. All workers were interviewed and examined by the pulmonologist. PFT and chest radiography were conducted for all subjects. HRCT was performed for those with abnormal PFT or chest radiography. Results: A total of 51% and 31% of the cotton textile workers had one or more respiratory symptoms and respiratory signs respectively. 28% of subjects in the exposed group and 5% of subjects in unexposed group had obstructive pattern. Bronchia wall thickening and air trapping were the most frequent chest radiography and HRCT abnormalities respectively. There was a significant correlation between HRCT and the results of PFT. Conclusion: We conclude that long term exposure to cotton dust is associated with obstructive disease that increase with duration of exposure (history of working years, also use of HRCT as a sensitive tool in the assessment of pathologic changes and it's correlation with PFT, confirms the expected pathophysiology of airway obstruction in cotton workers.

    1982-01-01

    Following previous work carried out in an Italian factory producing carbon electrodes and evaluating the occupational mutagenic-carcinogenic hazards, the authors studied the presence of mutagen metabolites in the urine of workers in the same factory who were exposed to petroleum coke and pitch and in the urine of a control group of unexposed workers. The urine samples were concentrated by absorption on XAD-2 columns and were tested using the Salmonella/microsome assay (strain TA98, TA100, TA1535, TA1538) with and without the addition of beta-glucuronidase and metabolizing system. The collection of urine samples was carried out twice, with an interval of 2 months; 'before working time', 'after working time', and also during Sunday. The results showed that urine samples collected 'before' occupational exposure (upon waking) or on Sunday revealed no mutagenic activity in either worker groups and that the urine samples collected after or during occupational exposure revealed high mutagenic activity in the exposed workers, with a statistically significant difference between the mean of the revertants/plate values for exposed and unexposed workers. On the basis of the previous and the present research, the authors suggest that application of the Salmonella/microsome test to work environments could offer useful and suitable tool for evaluating the health hazards due to mutagenic/carcinogenic substances from occupational exposure.

    The aim of this study was to investigate thiol/disulfide homeostasis in asphalt workers who are exposed to polycyclic aromatic hydrocarbons occupationally. The study was carried out in 34 nonsmoker asphalt workers. Additionally, 35 healthy nonsmoker volunteers were recruited as control group. Thiol and disulfide concentrations were determined using the novel automated measurement method. Levels of urinary 1-OH-pyrene were analyzed by liquid chromatography. Disulfide/thiol ratio was significantly higher in exposed group (p = .034). Also, a positive correlation was detected between disulfide/thiol ratio and 1-OH-pyrene values (r = .249, p = .036). Thiol/disulfide homeostasis was found to be disturbed in asphalt workers. The novel test used in this study may be useful for evaluating the oxidative status in polycyclic aromatic hydrocarbon (PAH) exposure.

Results indicated that traditional and field faculty were more civic-minded than new graduates and other practitioners. Social work educators who focused on raising civic awareness in courses were more civic-minded than colleagues. New graduates who had participated in club service events were more civic-minded; however, there was no significant differences between groups based on number of community service courses completed. Social workers, whether faculty or not, who had participated in collaborative research were more civic-minded. The authors conclude that how social workers view their commitment to civic engagement has implications. Social workers need to be vigilant in our commitment to well-being in society. Intentional practices could be implemented to strengthen the partnership among groups.

    The lung function impairment is the most common respiratory problem in industrial plants and their vicinity. Therefore, the purpose was to study the affects of wood dust and its duration of exposure on lung function. This was a matched cross-sectional study of Spirometry in 46 non-smoking wood workers with age range 20 - 60 years, who worked without the benefit of wood dust control ventilation or respiratory protective devices. Pulmonary function test was performed by using an electronic Spirometer. Significant reduction was observed in the mean values of Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), and Maximum Voluntary Ventilation (MVV) in wood workers relative to their matched controls. This impairment was increased with the duration of exposure to wood industries. It is concluded that lung function in wood workers is impaired and stratification of results shows a dose-response effect of years of wood dust exposure on lung function.

    Full Text Available Background: Incinerator workers are not considered to have arsenic overexposure although they have the risk of overexposure to other heavy metals. Aim: To examine the relationship between arsenic burden and risk of occupational exposure in employees working at a municipal refuse incinerator by determining the concentrations of arsenic in the blood and urine. Settings and Design: The workers were divided into three groups based on their probability of contact with combustion-generated residues, namely Group 1: indirect contact, Group 2: direct contact and Group 3: no contact. Healthy age- and sex-matched residents living in the vicinity were enrolled as the control group. Materials and Methods: Heavy metal concentrations were measured by atomic absorption spectrophotometer. Downstream rivers and drinking water of the residents were examined for environmental arsenic pollution. A questionnaire survey concerning the contact history of arsenic was simultaneously conducted. Statistical analysis: Non-parametric tests, cross-tabulation and multinomial logistic regression. Results: This study recruited 122 incinerator workers. The urine and blood arsenic concentrations as well as incidences of overexposure were significantly higher in the workers than in control subjects. The workers who had indirect or no contact with combustion-generated residues had significantly higher blood arsenic level. Arsenic contact history could not explain the difference. Airborne and waterborne arsenic pollution were not detected. Conclusion: Incinerator workers run the risk of being exposed to arsenic pollution, especially those who have incomplete protection in the workplace even though they only have indirect or no contact with combustion-generated pollutants.

    We reported recently that 1-bromopropane (1-BP; n-propylbromide, CAS Registry no. 106-94-5), an alternative to ozone-depleting solvents, is neurotoxic and exhibits reproductive toxicity in rats. The four most recent case reports suggested possible neurotoxicity of 1-BP in workers. The aim of the present study was to establish the neurologic effects of 1-BP in workers and examine the relationship with exposure levels. We surveyed 27 female workers in a 1-BP production factory and compared 23 of them with 23 age-matched workers in a beer factory as controls. The workers were interviewed and examined by neurologic, electrophysiologic, hematologic, biochemical, neurobehavioral, and postural sway tests. 1-BP exposure levels were estimated with passive samplers. Tests with a tuning fork showed diminished vibration sensation of the foot in 15 workers exposed to 1-BP but in none of the controls. 1-BP factory workers showed significantly longer distal latency in the tibial nerve than did the controls but no significant changes in motor nerve conduction velocity. Workers also displayed lower values in sensory nerve conduction velocity in the sural nerve, backward recalled digits, Benton visual memory test scores, pursuit aiming test scores, and five items of the Profile of Mood States (POMS) test (tension, depression, anxiety, fatigue, and confusion) compared with controls matched for age and education. Workers hired after May 1999, who were exposed to 1-BP only (workers hired before 1999 could have also been exposed to 2-BP), showed similar changes in vibration sense, distal latency, Benton test scores, and depression and fatigue in the POMS test. Time-weighted average exposure levels in the workers were 0.34-49.19 ppm. Exposure to 1-BP could adversely affect peripheral nerves or/and the central nervous system.

  1. Immigrants and Native Workers

    DEFF Research Database (Denmark)

    Foged, Mette; Peri, Giovanni

    Using a database that includes the universe of individuals and establishments in Denmark over the period 1991-2008 we analyze the effect of a large inflow of non-European (EU) immigrants on Danish workers. We first identify a sharp and sustained supply-driven increase in the inflow of non......-EU immigrants in Denmark, beginning in 1995 and driven by a sequence of international events such as the Bosnian, Somalian and Iraqi crises. We then look at the response of occupational complexity, job upgrading and downgrading, wage and employment of natives in the short and long run. We find...... that the increased supply of non-EU low skilled immigrants pushed native workers to pursue more complex occupations. This reallocation happened mainly through movement across firms. Immigration increased mobility of natives across firms and across municipalities but it did not increase their probability...

  3. Exposure scenarios for workers.

    Marquart, Hans; Northage, Christine; Money, Chris

    2007-12-01

    The new European chemicals legislation REACH (Registration, Evaluation, Authorisation and restriction of Chemicals) requires the development of Exposure Scenarios describing the conditions and risk management measures needed for the safe use of chemicals. Such Exposure Scenarios should integrate considerations of both human health and the environment. Specific aspects are relevant for worker exposure. Gathering information on the uses of the chemical is an important step in developing an Exposure Scenario. In-house information at manufacturers is an important source. Downstream users can contribute information through direct contact or through their associations. Relatively simple approaches (Tier 1 tools, such as the ECETOC Targeted Risk Assessment and the model EASE) can be used to develop broad Exposure Scenarios that cover many use situations. These approaches rely on the categorisation of just a few determinants, including only a small number of risk management measures. Such approaches have a limited discriminatory power and are rather conservative. When the hazard of the substance or the complexity of the exposure situation require a more in-depth approach, further development of the Exposure Scenarios with Tier 2 approaches is needed. Measured data sets of worker exposure are very valuable in a Tier 2 approach. Some downstream user associations have attempted to build Exposure Scenarios based on measured data sets. Generic Tier 2 tools for developing Exposure Scenarios do not exist yet. To enable efficient development of the worker exposure part of Exposure Scenarios a further development of Tier 1 and Tier 2 tools is needed. Special attention should be given to user friendliness and to the validity (boundaries) of the approaches. The development of standard worker exposure descriptions or full Exposure Scenarios by downstream user branches in cooperation with manufacturers and importers is recommended.

    Full Text Available Background: Thousands of chemical compounds are used in paint products, like pigments, extenders, binders, additives, and solvents (toluene, xylene, ketones, alcohols, esters, and glycol ethers. Paint manufacture workers are potentially exposed to the chemicals present in paint products although the patterns and levels of exposure to individual agents may differ from those of painters. The aim of the present study was to evaluate genome damage induced in peripheral blood lymphocytes and oral mucosa cells of paint industry workers. Materials and Methods: Genotoxicity was evaluated using the alkaline Comet assay in blood lymphocytes and oral mucosa cells, and the Micronucleus test in oral mucosa cells. For the micronucleus test in exfoliated buccal cells, no significant difference was detected between the control and paint industry workers. Results: The Comet assay in epithelia buccal cells showed that the damage index (DI and damage frequency (DF observed in the exposed group were significantly higher relative to the control group ( P≤0.05. In the same way, the Comet assay data in peripheral blood leukocytes showed that both analysis parameters (DI and DF were significantly greater than that for the control group ( P≤0.05. Conclusions: Chronic occupational exposure to paints may lead to a slightly increased risk of genetic damage among paint industry workers.

    The objective of this study was to characterise the injury epidemic and injury prevention needs of migrant workers in Shanghai. Cluster random sampling was applied in selecting subjects in migrant gathering areas, and face-to-face interview survey was conducted in this study. In this survey, 1256 migrant workers were included, among which the injury incidence in last one year was 38.3%. The first four injuries were incised and penetrating injury (9.5%), falls (7.2%), traffic injury (6.3%) and burns (5.3%). The injury incidence of male workers was significantly higher than that of female workers (χ(2) = 22.7, P workers were at the highest risk of getting injured. About 60.7% of injury episodes happened at a residence. The longest period of absence from work was up to 3 months due to falls, while the highest medical expense was near 9999 CNY ($1464.2) caused by traffic injury. About 62.9% of migrant workers need services on injury prevention. It is concluded that compared with urban registered residents, migrant workers have significantly higher incidence of injury in Shanghai. Injury prevention services are in urgent demand among the migrant workers.

    1. The workers' compensation system provides benefits to workers who are injured or made ill in the course of employment or their dependents regardless of fault. 2. The current workers' compensation laws benefit both the employer and the employee; however, workers' compensation is an exclusive remedy which bars recovery through a negligence lawsuit. 3. Workers' compensation regulations interact with other federal statutes such as the Americans With Disabilities Act and the Family Medical Leave Act. 4. Workers' compensation covers occupational injuries and occupational diseases, which may include cumulative trauma and mental stress claims. Nurses may be instrumental in evaluating and planning for an injured employee's return to work and occasionally in detecting fraudulent claims.

    Full Text Available Introduction: Cement has long been known as a cause of both irritant and allergic contact dermatitis. However, there are little data relating to occupational skin diseases (OSD in the Iranian construction industry. The aim of this study is to evaluate the epidemiology of cement dermatitis among terrazzo and cement manufactory workers. Methods: This is cross-sectional descriptive study. In this study 50 cement manufact-ory workers in Shahroud and 150 terrazzo workers in Lordegan were interviewed through questionnaire. Questionnaire includes demographic characteristics and questions about present dermatitis, background eczema, daily work hours, exposed chemical agents, using of gloves. Patients examined and patch tested by dermatologist. Data analyzed with SPSS software and c2, Mann Whitney and logistic regression statistical test. Results: The findings of the study showed that 8 workers (16% in cement factories and 52 workers (34.7% in Lordegan terrazzo enterprises had reported dermatitis at the time of review. Of which 15.5% in terrazzo workers had allergic contact dermatitis. In this study the prevalence of cement dermatitis increased with increasing age and there was significantly differences between dermatitis and background of dermatitis in terrazzo workers (P<0.05. Conclusion: Cement should be treated as hazardous materials, wearing of suitable gloves, early diagnosis and treatment of contact dermatitis and health education to workers is suggested.

    While a negative correlation between reproduction and life span is commonly observed, specialized reproductive individuals outlive their non-reproductive nestmates in all eusocial species, including the honeybee, Apis mellifera (L). The consequences of reproduction for individual life expectancy can be studied directly by comparing reproductive and non-reproductive workers. We quantified the life span consequences of reproduction in honeybee workers by removal of the queen to trigger worker reproduction. Furthermore, we observed the social behavior of large cohorts of workers under experimental and control conditions to test for associations with individual life expectancy. Worker life expectancy was moderately increased by queen removal. Queenless colonies contained a few long-lived workers, and oviposition behavior was associated with a strong reduction in mortality risk, indicating that a reproductive role confers a significant survival advantage. This finding is further substantiated by an association between brood care behavior and worker longevity that depends on the social environment. In contrast, other in-hive activities, such as fanning, trophallaxis, and allogrooming did not consistently affect worker life expectancy. The influence of foraging varied among replicates. An earlier age of transitioning from in-hive tasks to outside foraging was always associated with shorter life spans, in accordance with previous studies. In sum, our studies quantify how individual mortality is affected by particular social roles and colony environments and demonstrate interactions between the two. The exceptional, positive association between reproduction and longevity in honeybees extends to within-caste plasticity, which may be exploited for mechanistic studies.

Work-place alcohol use and drug use, intoxication at work, industry and occupation of employment. Secondary analysis of a large nationally representative survey involving descriptive and weighted multivariate logistic regressions. Differential patterns were identified by drug type, worker characteristics and occupational setting, controlling for demographic variables. Nearly 9% of workers surveyed (8.7%) usually drank alcohol at work and 0.9% usually used drugs at work. Attending work under the influence of alcohol was more prevalent (5.6%) than attending work under the influence of drugs (2.0%), and significantly more likely among young, male, never married workers with no dependent children. Hospitality industry workers were 3.5 times more likely than other workers to drink alcohol and two to three times more likely to use drugs at work or attend work under the influence of alcohol or drugs. Other high-risk industries and occupations included construction, financial services, tradespersons and unskilled workers. More than one in 20 Australian workers admit to having worked under the influence of alcohol and almost one in 50 report attending work under the influence of psychoactive drugs. The rates are higher for some industries, such as the hospitality industry, than others. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was assessed. For each worker size category olfactory responses to Dufour gland extracts were determined using electroantennography (EAG). Gas chromatography and mass spectrometry (GC-MS) were used to determine the chromatographic profile of Dufour gland secretion for each worker size. Morphometric measures permitted to classify the workers of S. geminata as large, medium and small workers. Medium S. geminata workers displayed a significantly higher behavioral response to Dufour gland extracts produced by medium size workers. Similarly, medium workers showed a significantly higher EAG response to Dufour gland extracts produced by medium sized workers. Chromatographic profile of Dufour gland secretions produced by workers showed that each size category exhibited a characteristic profile of the three main components considered as potential trail pheromone constituents. This work showed that medium workers of S. geminata exhibited a high trail-following behavior as well as a high antennal response to Dufour gland secretion. This and their relative abundance in field foraging areas, suggest that medium-sized workers are specialized in foraging activities. (author)

    This study describes the pattern of medical care provided to workers with schistosomiasis, estimate the total medical cost and to identify the proportional rates of sickness retirement attributed to schistosomiasis. The observational approach was adopted for this study 170 schistosomiasis workers and a similar number of controls were included in this study. An interviewing schedule and a special format were designed for collecting personal, medical and early retirement data. The results revealed that the mean total cost in the outpatient clinics was significantly higher for schistosomiasis workers than their controls (320.2 " 330.11 versus 210.8 " 260.01 L.E). The hospital cost was also higher for schistosomiasis workers compared with their controls (265.9 " 674.47 vs 195.8 " 629.72 L.E) but this differencewas not statistically significant. More than 80% of the total hospital cost was spent on bed cost. The average operative cost/worker was significantly higher among the schistosomiasis workers than the control workers (7.08 " 22.07 vs 2.35 " 5.2 L.E). The total medical cost (outpatient and hospital) was significantly higher for workers with schistosomiasis compared with their controls (586.02" 845.77 vs 406.57 " 694.34). The total number of workers who retired because of sickness disability other than schistosomiasis increased from 1994 to 1998 with a ratio of 2.54 while those who retired because of schistosomiasis and its complications increased with a ratio of 3.64.

    2002-01-01

    Occupational health has always operated at the intersection of corporate economic concerns and worker health. Conflicting demands on the loyalty of occupational health professionals by the interests of labor and industry have made negotiating this minefield an essential part of the practice of occupational medicine. In recent years, occupational health professionals have found themselves increasingly required to rationalize worker health measures with economic arguments. This has led to physician engagement in the realm of defining and measuring worker productivity. Ethical guidelines that hold worker health as a top priority are critical in preserving the responsibility of occupational physicians to their patients.

    2009-01-01

    Perception and knowledge of the TB-infection risk in healthcare workers (HCWs) changed profoundly in Germany during the past few years. Molecular-epidemiological studies and a comprehensive review of the existing evidence concerning the infection risk for HCWs lead to the conclusion that TB in HCWs is often caused by infection at the workplace. In the Hamburg Fingerprint Study, 80 % of the TB cases in HCWs were caused by infections at the workplace. In a similar Dutch study 43 % of all cases were work-related. Besides of the well-known risks in TB wards and laboratories, an increased risk for infection should be assumed for paramedics, in emergency rooms, for HCWs caring for the elderly or for workers with close contact to high-risk groups (homeless people, i. v. drug users, migrants from high-incidence countries). TB in a HCW working in these fields can be recognised as an occupational disease (OD) without identifying a particular source of infection. For all other HCWs, the German occupational disease law requires the identification of a source case before TB in an HCW can be accepted as an OD. Even though the proportion of work-related TB in HCWs is higher than was assumed before previously, the prevalence of latent TB infection (LTBI) is lower than expected. In an ongoing evaluation study of the interferon-gamma release assay (IGRA) LTBI prevalence in HCWs is 10 %. Prevention strategies in Germany should be reconsidered in the light of these new findings.

    Through the survey of direct economic remuneration, indirect economic remuneration and non-economic remuneration of employees in flat panel furniture enterprises in Chengdu City, we conduct a comparative analysis of the problems and causes of remuneration difference between migrant workers and non-migrant workers. The results show that the wage difference between migrant workers and non-migrant workers is the biggest, and there is little difference in terms of interests safeguarding and non-economic factors. The reason for the above results lies in the difference of education level; gender, region, household registration and other issues have little impact on the above results. The following recommendations are put forward to improve the remuneration of migrant workers: increasing government’s policy advocacy efforts and eliminating subjective offense; establishing the administrative oversight bodies and effectively safeguarding the legitimate rights and interests of migrant workers; strengthening vocational training for migrant workers, so that workers have more choices on positions; improving the working environment and developing good working atmosphere.

    1992-09-01

    This study investigated the occupational exposure to carbon monoxide (CO) of a group of blast furnace workers from an integrated steelworks, compared to a control group having no significant occupational CO exposure from other areas in the same works. The study was undertaken in 1984 at Port Kembla, New South Wales. Carboxyhaemoglobin (COHb) levels before and after an eight-hour work shift were measured in 98 male steelworkers: 52 from two CO-exposed iron blast furnaces and 46 controls from production areas in the same steelworks. The sample was stratified by smoking habits. Environmental air CO levels had been found to be consistently higher on one furnace than on the other. Absorption of CO from the working environment occurred in workers on the blast furnace with higher CO levels, regardless of smoking habits. On this blast furnace, some readings of COHb levels after a workshift in nonsmokers approached the proposed Australian occupational limit of 5 per cent COHb saturation. Overall, workers with the highest occupational exposure who smoked most heavily had the highest absorption of CO over a work shift. Biological monitoring gives an accurate measure of individual worker 'dose' of CO from all sources. Both environmental monitoring and biological monitoring need to be included as part of a program for controlling occupational CO exposure.

    Full Text Available BACKGROUND: The prevalence of the metabolic syndrome (MS has significantly increased over the last few decades and has become a main health challenge worldwide. Prevalence of MS is quickly rising in developing countries due to changing lifestyle. It was considered worthwhile to study MS and its components in granite workers since granite factories are situated in and around Khammam area. Moreover, no studies of MS in granite workers have been reported in literature. OBJECTIVES: Aim of our study is to assess the prevalence of metabolic syndrome and its components in granite workers. MATERIALS AND METHODS: 210 male workers in the age group of 20 - 50 working in granite industries located in and around the Khammam town of Telangana State are selected for the present study. Blood pressures (BP, waist circumference (WC were measured. Fasting blood samples were collected for the estimation of glucose and lipids. RESULTS: 69 subjects out of 210 were identified as having MS based on updated National cholesterol education programme - Adult Treatment Panel III (NCEP - ATP III guidelines. CONCLUSION: MS should be identified and remedial measures may be suggested, so that the risk of hypertension, cardiovascular risk, diabetes and the resultant morbidity is minimized and can be delayed

    Smoking is still now the main avoidable cause of disease, disability and mortality in industrialized countries. This habit is still very common in workplaces, where anti-smoke efforts seem to be less incisive than among general populations. The study analyzed the diffusion of smoke habit in 8111 male workers in Campania region, employed in different work activities (white collars, blue collars, drivers, cleaning civil servants, porters), so as to evaluate work related features, affecting its assumption and maintenance. Among all workers, smokers prevalence (42.7%) was higher than national male population. Percentages of smokers were highest among drivers (60.7%) and civil servants (52.5%), slightly lower among industry workers (47.3%) and lower among white collars (36.4%). The highest prevalence were found in 41-50 years age group (46.8%), but only among white collars aging was associated with higher smokers prevalence. Lower education degrees and two working variables, shifts and handwork, have been related with significantly smoking habit assumption. Results emphasized that health promotional programs are necessary to reduce smoke habit among workers, particularly among professionally and culturally unqualified subgroups.

    We compared the blood lead and other lead biomarkers between migrant and native workers with a focus on the impact of the legal employment permit system that was effective from 2003, which required employers to provide mandatory annual health examinations for migrant workers on lead biomarkers in 1997 and 2005. The mean blood lead level of migrant workers was 59.5 ± 19.4 μg/dl, yielding 47% of lead poisoning cases, which was significantly higher than that of native workers (36.8 ± 14.5 μg/dl; 11% of lead poisoning cases) in 1997 before enactment of the act. The overall mean blood ZPP levels and ALAU of migrant workers were significantly higher than those of native workers. In 2005, after new migrant worker regulations were instituted, the mean value of above lead biomarkers workers was still significantly higher than that of native workers, but the magnitude of the differences was smaller compared with the difference in 1997. We confirmed that the 2003 regulations played an important role in improving the health of migrant workers in the lead industry in terms of their blood lead levels and other lead biomarkers.

    The production of indium-tin oxide has increased, owing to the increased manufacture of liquid-crystal panels. It has been reported that interstitial pneumonia occurred in two indium-processing workers; therefore, the present study aimed to evaluate whether interstitial pulmonary disorders were prevalent among indium workers. The study was carried out in 108 male workers in the indium plant where the two interstitial pneumonia patients mentioned above were employed, and included high-resolution computed tomography (HRCT) of the lungs, pulmonary function tests and analysis of serum sialylated carbohydrate antigen KL-6 and the serum indium concentration. Significant interstitial changes were observed in 23 indium workers on HRCT and serum KL-6 was abnormally high (>500 U x mL(-1)) in 40 workers. Workers with serum indium concentrations in the highest quartile had significantly longer exposure periods, greater HRCT changes, lower diffusing capacity of the lung for carbon monoxide and higher KL-6 levels compared with those in the lowest quartile. The serum indium concentration was positively correlated with the KL-6 level and with the degree of HRCT changes. In conclusion, the results of the present study indicated that serum KL-6 and high-resolution computed tomography abnormalities were prevalent among indium workers and that these abnormalities increased with the indium burden, suggesting that inhaled indium could be a potential cause of occupational lung disease.

    Between 15 and 20% of prevalent cases of chronic obstructive pulmonary disease (COPD) have been attributed to occupational exposures to vapours, gases, dusts and fumes. Dust at construction sites is still a challenge, but no overview exists of COPD among construction workers. To assess the occurrence of COPD among construction workers. We performed a systematic search in PubMed and Embase between 1 January 1990 and 31 August 2016 in order to identify epidemiological studies with a risk estimate for either COPD morbidity/mortality or a spirometry-based definition of airway obstruction among workers in the construction industry. The authors independently assessed studies to determine their eligibility and performed a quality assessment of the included papers. Twelve studies were included. Nine studies found a statistically significant association between COPD and work in the construction industry, although only among never-smokers in one study and only for the period after 2000 in another study. One study found that the annual decline in forced expiratory volume in 1 s was significantly higher among construction workers compared with bus drivers. This review suggests that COPD occurs more often among construction workers than among workers who are not exposed to construction dust. It is not possible to draw any conclusions on specific subgroups as most studies analysed construction workers as one united group. In addition, no potential exposure-effect relationship could be identified.

    Full Text Available Background: Exposure to organic solvents is common among workers.Objective: To assess neurobehavioral effects of long-term exposure to organic solvents among rubber workers in Tehran, Iran.Methods: Across-sectional study was conducted on 223 employees of a rubber industry. The participants completed a data collection sheet on their occupational and medical history, and demographic characteristics including age, work experience, education level; they performed 6 psychiatric tests on the neurobehavioral core test battery (NCTB that measure simple reaction time, short-term memory (digit span, Benton, eye-hand coordination (Purdue pegboard, pursuit aiming, and perceptual speed (digit symbol.Results: Workers exposed and not exposed to organic solvents had similar age and education distribution. The mean work experience of the exposed and non-exposed workers was 5.9 and 4.4 years, respectively. The exposed workers had a lower performance compared to non-exposed workers in all psychomotor tests. After controlling for the confounders by logistic regression analysis, it was found that exposure to organic solvents had a significant effect on the results of digit symbols, digit span, Benton, aiming, and simple reaction time tests. No significant effect was observed in pegboard test.Conclusion: Occupational exposure to organic solvent can induce subtle neurobehavioral changes among workers exposed to organic solvents; therefore, periodical evaluation of the central nervous system by objective psychomotor tests is recommended among those who are chronically exposed to organic solvents.

    To investigate the prevalence of musculoskeletal complaints among male and female production workers in different types of seafood industries in North Norway and to analyse associations between musculoskeletal symptoms and some possible risk factors in the seafood industry. A self-administered anonymous questionnaire, covering several aspects concerning occupational environment and health issues, was mailed to employees in seafood-processing plants in North Norway. A total of 1767 employees in 118 seafood-processing plants participated giving a 50% response rate. This included 744 production workers in whitefish, shrimp and salmon industries, and 129 administrative workers in all types of seafood industries. The prevalence of musculoskeletal symptoms was high among seafood production workers. The odds ratio for symptoms from upper limbs was significantly higher for females compared to men. Production workers had the highest relative risk for symptoms from wrist/hands (OR = 4.1-9.4) and elbows (OR = 3.5-5.2) when compared to administrative workers. The main difference between types of seafood industries was the high prevalence of symptoms from wrist/hands among female (82%) and male (64%) production workers in the salmon industry compared to whitefish (62 and 47%, respectively) and shrimp industry (66 and 37%, respectively). Musculoskeletal symptoms were found among the majority of production workers in the whitefish, shrimp and salmon industry, the highest prevalence being among female workers. The main difference between types of seafood industries was the high prevalence of symptoms from wrist/hands among workers in the salmon industry. Cold work was an important risk factor for musculoskeletal symptoms.

    When a honeybee colony loses its queen, workers activate their ovaries and begin to lay eggs. This is accompanied by a shift in their pheromonal bouquet, which becomes more queen like. Workers of the Asian hive bee Apis cerana show unusually high levels of ovary activation and this can be interpreted as evidence for a recent evolutionary arms race between queens and workers over worker reproduction in this species. To further explore this, we compared the rate of pheromonal bouquet change between two honeybee sister species of Apis cerana and Apis mellifera under queenright and queenless conditions. We show that in both species, the pheromonal components HOB, 9-ODA, HVA, 9-HDA, 10-HDAA and 10-HDA have significantly higher amounts in laying workers than in non-laying workers. In the queenright colonies of A. mellifera and A. cerana, the ratios (9-ODA)/(9-ODA + 9-HDA + 10-HDAA + 10-HDA) are not significantly different between the two species, but in queenless A. cerana colonies the ratio is significant higher than in A. mellifera, suggesting that in A. cerana, the workers' pheromonal bouquet is dominated by the queen compound, 9-ODA. The amount of 9-ODA in laying A. cerana workers increased by over 585% compared with the non-laying workers, that is 6.75 times higher than in A. mellifera where laying workers only had 86% more 9-ODA compared with non-laying workers.

    The primary objective of this study was to identify determinants of inhalation and dermal exposure to polycyclic aromatic compounds (PACs) among asphalt paving workers. The study population included three groups of highway construction workers: 20 asphalt paving workers, as well as 12 millers and 6 roadside construction workers who did not work with hot-mix asphalt. During multiple consecutive work shifts, personal air samples were collected from each worker's breathing zone using a Teflon filter and cassette holder connected in series with an XAD-2 sorbent tube, while dermal patch samples were collected from the underside of each worker's wrist. All exposure samples were analyzed for PACs, pyrene and benzo[a]pyrene. Inhalation and dermal PAC exposures were highest among asphalt paving workers. Among paving workers, inhalation and dermal PAC exposures varied significantly by task, crew, recycled asphalt product (RAP) and work rate (inhalation only). Asphalt mix containing high RAP was associated with a 5-fold increase in inhalation PAC exposures and a 2-fold increase in dermal PAC exposure, compared with low RAP mix. The inhalation PAC exposures were consistent with the workers' proximity to the primary source of asphalt fume (paver operators > screedmen > rakers > roller operators), such that the adjusted mean exposures among paver operators (5.0 microg/m3, low RAP; 24 microg/m3, high RAP) were 12 times higher than among roller operators (0.4 microg/m3, low RAP; 2.0 microg/m3, high RAP). The dermal PAC exposures were consistent with the degree to which the workers have actual contact with asphalt-contaminated surfaces (rakers > screedmen > paver operators > roller operators), such that the adjusted mean exposures among rakers (175 ng/cm2, low RAP; 417 ng/cm2, high RAP) were approximately 6 times higher than among roller operators (27 ng/cm2, low RAP; 65 ng/cm2, high RAP). Paving task, RAP content and crew were also found to be significant determinants of

    The aim of the present study was to investigate how broad personality dimensions and dispositional resistance to change are associated with mastery of work among shift workers. A total of 285 shift workers employed in rotating shifts with morning, evening and night work and night shift schedules in a municipality in Norway completed electronic questionnaires. The findings suggest that the broad personality dimensions neuroticism and conscientiousness were significant predictors of perceived work mastery among shift workers in this sample, whereas the narrow trait dispositional resistance to change was not.

    Inclusive fitness theory predicts that in colonies of social Hymenoptera headed by a multiple-mated queen, workers should benefit from policing eggs laid by other workers. Foster & Ratnieks provided evidence that in the vespine wasp Dolichovespula saxonica, workers police other workers' eggs only in colonies headed by a multiple-mated queen, but not in those headed by a single-mated one. This conclusion, however, was based on a relatively small sample size, and the original study did not control for possible confounding variables such as the seasonal colony progression of the nests. Our aim, therefore, was to reinvestigate whether or not facultative worker policing occurs in D. saxonica. Remarkably, our data show that in the studied Danish population, there was no correlation between worker-worker relatedness and the percentage of worker-derived males. In addition, we show that variability in cuticular hydrocarbon profiles among the workers did not significantly correlate with relatedness and that workers therefore probably did not have sufficient information on queen mating frequency from the workers' cuticular hydrocarbon profiles. Hence, there was no evidence that workers facultatively policed other workers' eggs in response to queen mating frequency. Nevertheless, our data do show that the seasonal progression of the nest and the location in which the males were reared both explain the patterns of worker reproduction found. Overall, our results suggest that the earlier evidence for facultative worker policing in D. saxonica may have been caused by accidental correlations with certain confounding variables, or, alternatively, that there are large interpopulation differences in the expression of worker policing. © 2011 Blackwell Publishing Ltd.

    Exposure to coal dust leads to development of coal worker`s pneumoconiosis (CWP), a disease associated with accumulation of macrophages in lower respiratory tract. Mechanisms controlling monocyte recruitment are still poorly understood. Since monocyte chemoattractant protein-1 (MCP-1) is recognized as a potent chemotactic factor for blood monocytes, we tested for presence of MCP-1 in pulmonary compartment of patients with CWP. Bronchoalveolar lavage fluid (BALF) from 16 nonsmoking control subjects and 27 nonsmoking CWP patients (16 with simple pneumoconiosis (SP) and 11 with progressive massive fibrosis (PMF)) was analysed. Alveolar macrophages (AMs) were purified by adherence and BALF was concentrated 10x by lyophilization. MCP-1 was measured in BALF and in 3 h AM supernatants using a sandwich enzyme-linked immunosorbent assay. Localization of MCP-1 in lung tissue was determined by immunohistochemistry on tissue sections from three patients with CWP and two control subjects. MCP-1 levels were higher in concentrated BALF from patients with SP or PMF (median 370 and 555 pg x mL{sup -1}, respectively) than in those form control subjects (median 11 pg x mL{sup -1}) (p<0.001). Released MCP-1 in AM supernatants was enhanced in patients with CWP (median 83 pg x mL{sup -1}) but compared to controls (median 41 pg x mL{sup -1}) this level did not reach significance. Although significantly increased, AM counts in BALF from patients with CWP did not correlate with MCP-1 levels. MCP-1 levels in BALF correlated with MCP-1 levels in AM supernatants ({rho}=0.47; p<0.02). Data demonstrate that: 1) patients with coal worker`s pneumoconiosis have a marked pulmonary overproduction of monocyte chemoattractant protein-1; and 2) in addition to alveolar macrophages, fibroblasts (probably myofibroblasts) and hyperplastic type II pneumocytes may also be responsible for this increased level of monocyte chemoattractant protein-1 in coal worker`s pneumoconiosis.

    The objective of this study was to compare respiratory health of poultry workers in conventional cage, enriched cage and aviary layer housing on a single commercial facility, motivated by changing requirements for humane housing of hens. Three workers were randomly assigned daily, one to each of conventional cage, enriched cage, and aviary housing in a crossover repeated-measures design for three observation periods (for a total of 123 worker-days, eight different workers). Workers' exposure to particles were assessed (Arteaga et al. J Agromedicine. 2015;20:this issue) and spirometry, exhaled nitric oxide, respiratory symptoms, and questionnaires were conducted pre- and post-shift. Personal exposures to particles and endotoxin were significantly higher in the aviary than the other housings (Arteaga et al., 2015). The use of respiratory protection was high; the median usage was 70% of the shift. Mixed-effects multivariate regression models of respiratory cross-shift changes were marginally significant, but the aviary system consistently posted the highest decrements for forced expiratory volume in 1 and 6 seconds (FEV1 and FEV6) compared with the enriched or conventional housing. The adjusted mean difference in FEV1 aviary - enriched cage housing was -47 mL/s, 95% confidence interval (CI): (-99 to 4.9), P = .07. Similarly, for FEV6, aviary - conventional housing adjusted mean difference was -52.9 mL/6 s, 95% CI: (-108 to 2.4), P = .06. Workers adopting greater than median use of respiratory protection were less likely to exhibit negative cross-shift pulmonary function changes. Although aviary housing exposed workers to significantly higher respiratory exposures, cross-shift pulmonary function changes did not differ significantly between houses. Higher levels of mask use were protective; poultry workers should wear respiratory protection as appropriate to avoid health decrements.

    Welding is a process during which fumes, gases, electromagnetic radiation and noise are emitted as by-products. Metal oxide particles are particularly hazardous components of welding fumes. Welding has been found to be associated with respiratory symptoms and our objective in the present study was to study the effects of welding on pulmonary function and serum oxidant-antioxidant status. Fifty-one welding workers and 31 control subjects were recruited. Face to face interviews were conducted using the respiratory illness questionnaire adapted from the American Thoracic Society with the addition of demographic characteristics, work history and working conditions. Additionally physical examinations and spirometric measurements were performed at workplaces. Thiobarbituric acid reactive substances (TBARS), protein carbonyls, protein sulfhydryls (SH) and erythrocyte reduced glutathione (GSH) levels were measured to evaluate oxidant-antioxidant status in 34 welding workers and in 20 control subjects. No statistically significant differences were observed in age, height, weight, body mass index (BMI), smoking status and annual working durations between welding workers and controls. Coughing, sputting and wheezing were significantly higher in welding workers (pwelding work showed a significant risk for chronic bronchitis (OR: 4.78, 95%CI: 1.30-17.54). Forced expiratory volume in one second (FEV(1))/forced vital capacity (FVC) and four parameters of forced expiratory flow (FEF: FEF(25), FEF(50), FEF(75), FEF(25-75)) levels measured in the welding workers were significantly lower than those in the control group (pwelding workers than those in controls (pwelding workers chronically exposed to welding fumes and gases. Preventive measures should be taken to improve the health status of these workers.

    To understand the major causes of death in automobile foundry workers and investigate casting manipulations hazards to health. A cohort study of 3529 foundry workers registered in one big automobile factory in Shiyan city of China was performed. Standardized mortality ratios (SMRs) were calculated for the main causes of death by using Chinese national mortality rates as reference. The cohort mortality was traced from 1980 to the end of 2005 with an accumulation of 84 999 person-years, revealed 265 deaths. The results of this study showed that the standardized mortality ratio for all subjects was 0.96 (95% CI: 0.85 approximately 1.08), which was very close to that expected on the basis of the China national mortality rates. The SMR increased with age, the SMR became greater than 1 in all groups of age 50 and higher. The results showed that malignant neoplasm (3.43%), accidents (1.16%), cerebro-vascular diseases (1.08%), cardio-vascular diseases (0.79%) were the first four illnesses that threatened workers' life span. Statistically significant mortality of malignant neoplasm (SMR = 7.87), accidents (SMR = 2.70), cardio-vascular diseases (SMR = 2.68) and digestive diseases (SMR = 2.79) were found in the foundry workers. The relative risk of malignant neoplasm for first line workers to assistant workers was 1.99 (P < 0.05). The occupational hazards in foundry factory have harmful impact on the workers' health and life span.

    Full Text Available Due to the expansion of crop productions there has been an increase in the fertilizers’ use by farmers in Malaysia. Recently Sustainable Agricultural Practices (SAP is gaining attention within agricultural sector. The Department of Agriculture facilitates regular delivery of SAP knowledge to farmers through extension workers. However extension workers’ perceptions and knowledge on SAP is not known well in Malaysia. A survey of extension workers was conducted in peninsular Malaysia to identify their perceptions and knowledge about SAP and determine the extent to which extension workers communicate SAP to the farmers. A descriptive research design was used to collect data from 400 extension workers. Results suggest extension workers’ perceptions and knowledge of SAP are favorable. Extension workers indicated that they communicate SAP information to the farmers. Further investigation from farmers’ perspectives is required to discover to what extent extension plays significant role in promoting adoption of the program.

    Full Text Available Introduction Occupational injuries are the leading cause of morbidity and mortality among workers. The aim of this study was to analyze the frequency of occupational injuries and health status of workers. Material and methods The examined group consisted of 3.750 workers with health disorders. The control group included 1.800 healthy workers. Both groups were similar in terms of many factors that could contribute to the occurrence of occupational injuries. The injury rates were calculated in both groups. Results Workers with psychomotor and sensorimotor disorders, neuroses, obstructive sleep apnea, arterial hypertension, diabetes mellitus, hearing, vascular and sight impairments have been frequently injured compared to workers with other diseases. Discussion Due to the belief that accidents and occupational injuries are preventable, it is an imperative to study those factors which are likely to contribute to occurrence of accidents. The contributing factors could be the physical and mental state of workers. Conclusion Occupational injuries are significantly more common in the examined group than in controls.

    Waste management, namely, collection, transport, sorting and processing, and disposal, is an issue of social concern owing to its environmental impact and effects on public health. In fact, waste management activities are carried out according to procedures that can have various negative effects on the environment and, potentially, on human health. The aim of our study was to assess the potential effects on respiratory health of this exposure in workers in the waste management and disposal field, as compared with a group of workers with no occupational exposure to outdoor pollutants. The sample consisted of a total of 124 subjects, 63 waste collectors, and 61 office clerks. Informed consent was obtained from all subjects before inclusion in the study. The entire study population underwent pulmonary function assessments with spirometry and completed two validated questionnaires for the diagnosis of rhinitis and chronic bronchitis. Statistical analyses were performed using STATA 13. Spirometry showed a statistically significant reduction in the mean Tiffenau Index values in the exposed workers, as compared with the controls, after adjusting for the confounding factors of age, BMI, and smoking habit. Similarly, the mean FEV1 values were lower in the exposed workers than in the controls, this difference being again statistically significant. The FVC differences measured in the two groups were not found to be statistically significant. We ran a cross-sectional study to investigate the respiratory health of a group of workers in the solid waste collection and disposal field as compared with a group of office workers. In agreement with most of the data in the literature, our findings support the existence of a prevalence of respiratory deficits in waste disposal workers. Our data suggest the importance of adopting preventive measures, such as wearing specific individual protection devices, to protect this particular category of workers from adverse effects on respiratory

    Full Text Available Background: Raw sewage contains various pathogenic organisms including bacteria, viruses, fungus, worms and protozoa. Workers at wastewater treatment plants (WWTPs are exposed to these organisms as well as to H2S gas causing many health hazards. Objectives: To assess some work-related health effects among WWTPs workers with special emphasis on the most common infections as well as cardiopulmonary disorders. Methods: 43 workers at Berket Al-Sabih WWTPs were studied. An equal number of non-exposed comparison group were also studied. All participants were asked about their personal demographic data, symptoms suggesting infection, respiratory tract impairment and cardiovascular manifestations. Spirometric measurements were made at the end of the work shift. A resting standard 12-lead ECG was also taken for each participant. For those with a positive ECG finding, echocardiography was also performed. Serum examination for antibodies against hepatitis A virus (HAV and hepatitis E virus (HEV was also done. A heparinized blood sample to measure sulf-hemoglobin, as an indicator of H2S exposure, was taken. Stool was analyzed by polymerase chain reaction (PCR for Leptospira spirochete. Results: WWTPs workers suffered from body ache, abdominal pain, wheeze, asthma and dyspnea more frequently than the comparison group (p<0.05. An obstructive pattern of pulmonary function impairment and a higher mean sulf-hemoglobin% were significantly more common among WWTPs workers than the comparison group. Antibody levels against HAV and HEV as well as frequency of positive stool PCR test results for L. spirochete were significantly higher among WWTPs workers than the comparison group. The prevalence of left ventricular hypertrophy (LVH according to ECG and mean ejection fraction (EF as measured by echocardiography were significantly more frequent in WWTPs workers than in the comparison group. Conclusion: WWTPs workers are high risk of developing various infections and

    In this study, postural stability was measured with a microcomputer-based force platform as an indirect assessment of central nervous system effect in 28 sewer workers (age range 23.4 to 64.5 years, standard deviation of 8.7 years). All workers performed four 30-second postural sway tests. The organic-solvent exposure was measured by a photo-ionization detector. The photo-ionization detector was calibrated to measure volatile organic solvents in total benzene equivalence, and concentrations were measured in various parts of the plant. The mean exposure was .32 parts per million (ppm) benzene equivalent (range of .02 to .95 ppm, standard deviation .19 ppm). Based on a covariate adjusted linear multiple-regression model, a statistically significant (p organic-solvent exposure. These workers also had increased postural sway compared with a nonexposed population. The statistically significant correlation between postural sway determinations and organic-solvent exposure was surprising given the very low exposures measured. It is possible that the organic-solvent exposure might not be the causative agent, but rather that the solvents themselves correlate with some other causative exposure, ie, total volatile organics as implicated in the cause of sick-building syndrome.

    Full Text Available Introduction: Increasing heat waves-particularly in urban areas where construction is most prevalent, highlight a need for heat exposure assessment of construction workers. This study aims to characterize the effects of heat on construction workers from a site in Gandhinagar. Materials and Methods: This study involved a mixed methods approach consisting of a cross sectional survey with anthropometric measurements (n = 219 and four focus groups with construction workers, as well as environmental measurements of heat stress exposure at a construction site. Survey data was collected in two seasons i.e., summer and winter months, and heat illness and symptoms were compared between the two time periods. Thematic coding of focus group data was used to identify vulnerability factors and coping mechanisms of the workers. Heat stress, recorded using a wet bulb globe temperature monitor, was compared to international safety standards. Results: The survey findings suggest that heat-related symptoms increased in summer; 59% of all reports in summer were positive for symptoms (from Mild to Severe as compared to 41% in winter. Focus groups revealed four dominant themes: (1 Non-occupational stressors compound work stressors; (2 workers were particularly attuned to the impact of heat on their health; (3 workers were aware of heat-related preventive measures; and (4 few resources were currently available to protect workers from heat stress. Working conditions often exceed international heat stress safety thresholds. Female workers and new employees might be at increased risk of illness or injury. Conclusion: This study suggests significant health impacts on construction workers from heat stress exposure in the workplace, showed that heat stress levels were higher than those prescribed by international standards and highlights the need for revision of work practices, increased protective measures, and possible development of indigenous work safety standards for

    Pig farmers and veterinarians have high prevalence of methicillin-resistant Staphylococcus aureus (MRSA) due to the occupational livestock exposure, while few reported this association on slaughterhouse workers. We conducted this cross-sectional study to explore the phenotypic and molecular characteristics of S. aureus and MRSA in slaughterhouse pig-related workers and control workers in Guangdong Province, China. Participants were interviewed and provided two nasal swabs. Swabs were tested for S. aureus, and isolates were further tested for antimicrobial susceptibility, virulence genes and multi-locus sequence typing. Compared with control workers, pig-related workers have significantly higher prevalence of MRSA carriage (adjusted odd ratio (aOR) 3·70, 95% CI 1·63-8·40). The proportions of MRSA resistant to clindamycin, erythromycin, tetracycline or chloromycetin were significantly higher in pig-related workers than in control workers. The predominant phenotypes of S. aureus were resistant to penicillin, clindamycin, erythromycin and tetracycline. Three MRSA CC9 isolates with livestock-associated characteristics (resistance to tetracycline and absence of immune evasion cluster (IEC) genes) were detected in pig-related workers but not in control workers. For human-associated CCs (CC7, CC59, CC6, and CC188), there was no significant difference in IEC profile or antimicrobial resistance between the groups. These findings reveal that there may be a potential risk for livestock-to-human transmission of LA-MRSA and human-to-human transmission of human-associated MRSA.

    Case-control propensity matched. To compare clinical outcomes after lumbar fusion in patients receiving workers' compensation with a case-matched control group who are not on workers' compensation. Previous studies have demonstrated poor outcomes in patients receiving workers' compensation after lumbar fusion. However, a case-control study where patients are matched for covariates known to affect outcomes after lumbar fusion, including baseline clinical outcome measures, has not been done. From 783 patients who underwent posterolateral fusion with complete preoperative and 2-year postoperative outcome measures, 60 patients who were receiving workers' compensation were identified. Outcome measures included the Oswestry Disability Index (ODI), Short Form-36 (SF-36), and back and leg pain numerical rating scales. Propensity scoring technique was used to match these patients with a control group not receiving workers' compensation using sex, age, smoking status, body mass index, diagnosis, number of levels fused, preoperative ODI, SF-36 Physical Component Summary (PCS), SF-36 Mental Component Summary, and back and leg pain scores, producing 58 matched pairs. There were no significant differences between the demographics, job classification, and preoperative outcome scores in the two groups. At 2 years after operation, patients not receiving workers' compensation had a significantly greater improvement in ODI (P=0.009) and SF-36 PCS (P=0.007) compared with those receiving workers' compensation. Although patients not receiving workers' compensation had greater improvements in back and leg pain compared with those receiving workers' compensation, this did not reach statistical significance (P=0.079). The mean 2-year ODI, SF-36 PCS, and back pain raw scores of patients receiving workers' compensation were significantly lower than those not receiving workers' compensation. Only 19% of workers' compensation patients achieved minimum clinically important difference in terms

    Full Text Available The purpose of this study was to determine the level of heat stress to construction workers using Thermal Work Limit (TWL and Wet Bulb Globe Temperature (WBGT indices and by measuring Urine Specific Gravity (USG among construction workers in Iran and comparing the appropriateness of these indices for measuring heat stress in Iran climate.This comparative and experimental study was conducted during September 2012 in Baghe Ketabe Tehran, one of the large size construction sites in Tehran City, Iran. Sixty participants were randomly selected in two groups (exposed to sun and non-exposed among the construction workers in a construction campus with similar work type, climate and diet. TWL and WBGT and USG were measured in two consequent days and at the beginning, mid and end of the work shift, for both groups.The mean WBGT index was 22.6 ± 0.9 °C for control group and 27.5 ± 1.2 °C for exposure group, the mean TWL index measure was 215.8 ± 5.2 W/m(2 for control group and 144 ± 9.8 W/m(2 for exposure group and the mean USG was 1.0213 ± 0.0054 in control group and 1.026 ± 0.005 in exposure group. There was a significant difference in TWL, WBGT and USG between exposed and non-exposed group (P<0.01.workers were at an allowed level of heat stress. TWL, WBGT and USG measures were significantly correlated; however as TWL level enabled classification based on required intervention, it had some merit over WBGT index.

    Non-communicable diseases have emerged as a global health issue. Role of occupation in pathogenesis of non-communicable diseases has not been explored much especially in the hospitality industry. Objectives of this study include finding risk factor prevalence among hotel workers and studying relationship between occupational group and chronic disease risk factors chiefly high body mass index. A cross-sectional study was conducted among non-managerial employees from classified hotels in India. The study participants self-administered pre-designed pilot-tested questionnaires. The risk factor prevalence rates were expressed as percentages. Chi-square test was used for bi-variate analysis. Overweight was chosen as 'outcome' variable of interest and binary multi-logistic regression analysis was used to identify determinants. The prevalence rates of tobacco use, alcohol use, inadequate physical activity and inadequate intake of fruits and vegetables were 32%, 49%, 24% and 92% respectively among hotel employees. Tobacco use was significantly common among those in food preparation and service, alcohol use among those in food service and security and leisure time physical activity among front office workers. More than two-fifths (42.7%) were overweight. Among the hotel workers, those employed in food preparation and security had higher odds of 1.650 (CI: 1.025 - 2.655) and 3.245 (CI: 1.296 - 8.129) respectively of being overweight. Prevalence of chronic disease risk factors is high among hotel workers. Risk of overweight is significantly high in food preparation and security departments and workplace interventions are necessary to address these risks.

    This study evaluated inter-worker variability in lower body posture and work activity during highly-structured assembly line work. Data were collected from 79 unique assembly line workstations in an engine manufacturing plant. Because the plant utilized work teams, 4-8 workers rotated through each workstation. At least 30 min of videotape was collected from at least three workers at each workstation. A computer-assisted work sampling procedure randomly selected 200 video "freeze-frames" for each worker. Lower body posture/movement (e.g., sit, stand, walk, etc.) was determined for each frame and used to estimate the percentage of time the worker spent in various postures and activities. Chi-square analyses were performed for each workstation to assess the significance of inter-worker differences. Due to variations in individual work methods, significant differences (p <.05) were found at 57 out of 79 workstations (72%). The greatest differences occurred when workers had the option to choose between standing and sitting (significant in 8 of 8 cases; in extreme examples, sit time ranged between 0-100% on one job, and 6.5-98% on another). Studying a single worker (or "proxy") can contribute to substantial error when estimating exposures in workplace studies of ergonomic stressors, since the proxy may not be representative of all workers who perform the job. Individual measurements are preferable, particularly for jobs where workers have substantial latitude to develop individualized work methods.

    Full Text Available The focus of this article is on the use of Niklas Luhmann’s systems theoretical approach in order to analyse interviews conducted with media workers concerning their experiences of ethnic diversity in newsrooms. Applying systems theory means constructing the interview as a social system and seeing the “data” as observations produced by the observer and not as representations of a reality. The first part of the article describes the interview methodology and the second part provides examples, from the current study, of how systems theory can be applied in order to analyse interviews. Using a difference-theoretical approach means looking at the distinctions the informants make when talking about their experiences. These main guiding distinctions can be summarised as immigrant background/competence as well as advantage/competence. Using the guiding distinction of inclusion/exclusion when interpreting the interviewees’ statements, the interdependencies of mechanisms of inclusion and exclusion in newsrooms related to ethnic background can be examined.

    Previous studies have focused on how ants deal with workers infected by pathogens but how pupae are protected from infection by fungi is not well understood. The behavioral mechanisms adopted by Solenopsis invicta (red imported fire ants, RIFA) adult workers to protect pupae against Metarhizium anisopliae infection were studied. We observed the behavioral changes of M. anisopliae infected adult workers in the brood chamber as well as the behavioral changes of healthy workers to fungus exposed pupae. The time of fungus infected workers spent in the pupal chamber reduced significantly from 103.4 s on the first day to 38.5 s on the third day. Moreover, the percentage of time spending on brood care in the pupal chamber reduced significantly from 13.6% on the first day to 3.5% on the third day. When pupae were infected by M. anisopliae, workers performed 5.3 times more grooming to fungus exposed pupae than controls, and the duration of each grooming bout to fungus exposed pupae was 5.2 times longer than controls. Grooming did remove many conidia on the surface of fungus exposed pupae. The mean numbers of conidia on the surface of pupae were 103.1, 51.6 and 31.3 when no workers, two workers and ten workers accompanied a pupa, respectively. The presence of workers resulted in a lower germination rate of conidia on the surface of pupae. The mean germination rates of conidia after 20 h of inoculation on the surface of pupae were 95.1%, 80.4% and 59.9%, in the treatments with no worker, two workers and ten workers respectively. There was a positive correlation between the emergence rate of pupae and the number of accompanying workers. RIFA protect their pupae from infection by M. anisopliae through social be- haviors which enable the sustainable development of their population.

    Objective To detect the expression of Bcl-2 protein in lung tissues of coal worker' s pneumoconiosis(CWP) complicated with lung cancer and to explore the relationship between CWP and lung cancer and its molecular mechanism. Methods The dissected lung specimens of CWP were collected. Based on pathologic diagnosis, 54 cases of CWP and 10 cases of CWP complicated with lung cancer were selected as the study subject. Since to obtain healthy persons' lung tissue was very difficult, the lung tissues of normal structure at the side of pathological tissue from of 30 CWP were selected as the control. Bcl-2 gene proteins for all lung tissues were measured by immunohistochemical Elivision plus method. Chi-Square test and t test were used to analyze the data. Results The positive rates of Bcl-2 protein expression in tissues of the control, CWP and CWP complicated with lung cancer group were 16. 7%(5/30), 24. 1 %(13/54), and 90. 0%(9/10), respectively. The average values of optical density were 2. 08 ± 0. 16, 2. 51 ± 0. 19 and 3. 22 ± 0. 41, respectively. The positive rate of Bcl-2 protein expression in CWP complicated with lung cancer was significantly higher than that of CWP and the control tissue (P0. 05). Conclusions The expression of Bcl-2 protein distinctively increases in lung tissues of CWP complicated with lung cancer and CWP.

    Abstract Objectives An epoxy resin worker developed hypersensitivity pneumonitis requiring lung transplantation and had an abnormal blood lymphocyte proliferation test (LPT) to an epoxy hardener. We assessed the prevalence of symptoms, abnormal spirometry, and abnormal epoxy resin LPT results in epoxy resin workers compared to unexposed workers. Methods Participants completed questionnaires and underwent spirometry. We collected blood for epoxy resin LPT and calculated stimulation indices for five epoxy resin products. Results We compared 38 exposed to 32 unexposed workers. Higher exposed workers were more likely to report cough (OR 10.86, [1.23‐infinity], p = 0.030) or wheeze (OR 4.44, [1.00‐22.25], p = 0.049) than unexposed workers, even controlling for smoking. Higher exposed workers were more likely to have abnormal FEV1 than unexposed workers (OR 10.51, [0.86‐589.9], p = 0.071), although not statistically significant when adjusted for smoking. There were no differences in proportion of abnormal epoxy resin system LPTs between exposed and unexposed workers. Conclusions In summary, workers exposed to epoxy resin system chemicals were more likely to report respiratory symptoms and have abnormal FEV1 than unexposed workers. Use of epoxy resin LPT was not helpful as a biomarker of exposure and sensitization. PMID:26553118

    Full Text Available NGOs came into the society in their present form after World War II and more precisely in 1960s. Before that also different forms of philanthropy existed. Like elsewhere in the world, in Pakistan also state and the market were the two sectors catering for different needs of the people. When foreign funding started coming into the poor countries, the channel of NGOs was considered more appropriate including the fact they had roots in the society and the benefit could reach the far flung areas. NGO field workers are the real actors in the NGOs’ activities but sadly the NGOs those raise the slogans of working for the destitute do not bother to facilitate the NGO field workers. Eventually the NGO field workers are facing problems of job insecurity, poor salary structure, unhealthy working environment and even harassment especially in case of women NGO field workers in Pakistan

    Concern about the increasing incidence of hand dermatitis in floral shop workers in the United States and its possible association to the plant Alstroemeria, a flower that has become popular since its introduction in 1981, prompted investigation of the prevalence and cause of hand dermatitis in a sample of floral workers. Fifty-seven floral workers were surveyed, and 15 (26%) reported hand dermatitis within the previous 12 months. Sixteen floral workers (eight with dermatitis) volunteered to be patch tested to the North American Contact Dermatitis Group Standard and Perfume Trays, a series of eight pesticides and 20 plant allergens. Of four of seven floral designers and arrangers who reported hand dermatitis, three reacted positively to patch tests to tuliposide A, the allergen in Alstroemeria. Patch test readings for all other plant extracts were negative. A positive reading for a test to one pesticide, difolatan (Captafol), was noted, the relevance of which is unknown.

    In the processes of electronic and jewelry manufacturing, workers are employed to use their skill in tiny visual tasks (1-3 mm) and near visual distances (development and implementation of guidelines in the selected factories; and 3) a resurvey to document the change. The baseline survey was conducted in Samutprakan Province during October to December, 2003. Ninety-five percent of the sampled workers were female with an average age of 26.2 yr. Fifty-two percent of the workers had at least one kind of vision problem that might have affected their work performance, and 48.3% of the work sites had substandard illumination levels. The intervention included improvement of lighting conditions, the introduction of short breaks, and correction of visual performance problems. After the intervention, the inadequate lighting problem went down to 24.5%. All factories took a rest break and 20.5% of the workers with inadequate visual performance had corrected their vision in the intervention period. Comparing pre-intervention status with the end of the program, the Critical Fusion Frequency (CFF) at one hour and two hours of work were improved with statistical significance among the electronic but not the jewelry workers. In conclusion, visual problems among vision intensive industrial workers are common. Intervention programs partially but significantly improved the situation.

    To evaluate thiol-disulphide homeostasis - a novel, easily calculated, readily available, and relatively cheap oxidative stress marker - in radiation workers and compare the results with healthy controls. A total of 108 participants were enrolled in the study including 63 hospital workers occupationally exposed to ionizing radiation in the units of interventional radiology, interventional cardiology and nuclear medicine. A control group consisted of 45 individuals staff in the same hospital. Serum thiol-disulphide homeostasis measurement was investigated via the spectrophotometric method newly described by Erel and Neşelioğlu. The mean serum native thiol levels of radiation workers (528.96 ± 86.42 μmol/l) was significantly lower than control subjects (561.05 ± 104.83 μmol/l) (p = .045). The mean serum total thiol levels of radiation workers (547.70 ± 91.50 μmol/l) was lower than control subjects (580.36 ± 112.24 μmol/l). Nevertheless, there was no significant difference between total thiol of exposed workers and controls. The results show that long-term low dose ionizing radiation may lead to oxidative stress and have side-effects in antioxidant thiol groups. We may suggest supporting radiation workers by safe antioxidant nutritional formulations and following up via both physical dosimetry and biodosimetric methods.

    The author assesses the problem of illegal labor migration to Japan. "Labor policies, regulations, types of immigration violations, and the role of the recruitment industry are described. Most of the estimated 200,000 illegal workers are employed in small and medium sized enterprises, especially construction and manufacturing, which pay them wages well below the normal rate. A key issue is the infringement of human rights of these illegal workers, who lack the protection of labor laws and the social security system."

    To measure air pollutant concentrations in Chinese restaurant kitchens using different stove types and assess their influence on workers' respiratory health. 393 kitchen workers from 53 Chinese restaurants were surveyed over 16 months: 115 workers from 21 restaurants using only electric stoves and 278 workers from 32 restaurants using only gas stoves. Workers were interviewed about their respiratory symptoms and had their lung function tested. Concentrations of nitric oxide (NO), nitrogen dioxide (NO(2)), carbon monoxide (CO), carbon dioxide (CO(2)), methane (CH(4)), non-methane hydrocarbons (NMHC), total volatile organic compounds (TVOC) and fine particulate matter (PM(2.5)) were measured using portable monitors and air-bag sampling. Temperature and noise levels were assessed. Median concentrations of NO, NO(2) and CO were 7.4, 1.5 and 1.6 times higher in gas-fuelled kitchens than in electric ones and average concentrations of PM(2.5) and TVOC were 81% and 78% higher, respectively. Differences were smaller for CH(4) and NMHC. Electricity-run kitchens were 4.5°C cooler and 9 dBA less noisy than gas-fuelled ones. Workers using electric cookers had significantly better lung function than their gas-using counterparts and their mean FEV(1) and FVC values were 5.4% and 3.8% higher, respectively, after adjustment for confounders. Wheeze, phlegm, cough and sore throat were more prevalent in workers using gas. The adjusted OR for having phlegm regularly was significantly higher. The poorer lung function and higher prevalence of respiratory symptoms among workers in gas-fuelled kitchens compared to those in electricity-powered kitchens may be associated with exposure to higher concentrations of toxic air pollutants generated during gas cooking.

    Although byssinosis in jute mill workers remains controversial, studies in a few jute mills in West-Bengal, India, revealed typical byssinotic syndrome associated with acute changes in FEV1 on the first working day after rest. The present study on 148 jute mill workers is reported to confirm the occurrence of byssinosis in jute mill workers. Work related respiratory symptoms; acute and chronic pulmonary function changes among exposed workers were studied on the basis of standard questionnaire and spirometric method along with dust level, particle mass size distributions and gram-negative bacterial endotoxins. The pulmonary function test (PFT) changes were defined as per the recommendation of World Health Organization and of Bouhys et al. Total dust in jute mill air were monitored by high volume sampling, technique (Staplex, USA), Andersen cascade impactor was used for particle size distribution and personal exposure level was determined by personal sampler (Casella, London). Endotoxin in airborne jute dust was analysed by Lymulus Amebocyte Lysate (LAL) "Gel Clot" technique. Batching is the dustiest process in the mill. Size distribution showed that about 70-80% dust in diameter of jute mill workers are also suffering from byssinosis as observed in cotton, flask and hemp workers.

    Full Text Available Introduction. Municipal service workers have been found to have an occupational risk of leptospirosis. Study among municipality workers shows high seropositivity of leptospiral antibodies detected among town cleaners and garbage collectors. Objective. Aims of this study were to determine seroprevalence of leptospiral antibodies and distribution of serovars detected in samples among municipal service workers. Methodology. Cross-sectional study involved 89 municipal service workers in Selangor. Blood samples were taken and serological test was done using MAT following standard procedures. Results. Seropositivity of leptospiral antibodies among municipal service workers was 34.8%. Serovars identified were strains of Sarawak, Copenhageni, Hardjobovis, Lai, Bataviae, Patoc, Celledoni, Hardjoprajitno, Tarrasovi, and Pomona. There were 31 workers with positive leptospiral antibodies. All of them were frequently exposed towards leptospirosis. Significant associations have been reported between seropositivity of leptospiral antibodies with job category (P=0.021 and worker’s nationality (P=0.014 among municipal service workers. Conclusion. High seropositivity of leptospiral antibodies detected among municipal service workers which was associated with job category and nationality of workers. The significant findings from this study suggest that health education programs and safe work practice should be considered to prevent leptospirosis among municipal service workers in future.

    Medical consultation rates were compared between a group of lead workers and two groups of non-lead workers in a newspaper company where a serious industrial dispute took place over health effects of lead three years before this study. The comparison was also made within the group of lead workers. Maximal blood lead concentrations (PbBs) ranged from 0.1 ..mu..mol/kg to 3.6 ..mu..mol/kg with an average of 1.3 ..mu..mol/kg in the past three years. The consultation rate of lead workers was significantly higher than that of both the non-lead workers, when the number of workers who consulted physicians or dentists once or more for a year per 100 workers was compared. Disease-specific consultation rates were also higher in lead workers for seven categories of diseases and injuries such as hypertensive disease and peptic ulcers. When lead workers were divided into three groups by PbB or erythrocytes delta-aminolevulinic acid dehydratase (ALAD) levels, however, no significantly high rate was found in the higher PbB groups nor lower ALAD groups in terms of general and disease-specific consultation rates. It was concluded that the industrial dispute might have been a major cause of the high consultation rate of lead workers.

    Full Text Available Background: Job stress has been linked to a wide range of adverse effects on mental, physical and organizational health. Objective: The objective of this study was to determine the impact of job stress on mental, physical and social health of the underground construction workers in Sikkim. Materials and Methods: The study population comprised of tunnel workers and a comparable group of controls. Using the interview technique, data was collected using the SF-36 General Health Survey Questionnaire. Results: The study population comprised of individuals of whom more than half were below 40 years of age and was comparable to the group of controls. Majority reported good health, while poor health was reported by 22 % of the subjects under study Compared to their health status last year, 52% rated their health as somewhat worse. Majority reported that their physical health problems limited them in activities of daily life, viz., running, lifting heavy objects, participation in strenuous sports, climbing several flights of stairs, bending, stooping or kneeling and walking more than a mile, during the past four weeks. More than half of them had severe body ache in the past four weeks that interfered with both work outside home and housework. This was true for emotional problems also, which interfered with their normal social activities involving family, friends, neighbors or groups. The associations of occupational stress with physical, emotional and social life and with limitation of day-to-day activities among tunnel workers were found to be statistically significant. Conclusion: The results emphasize the importance of assessment of the effects of job stress and of fulfilling the need of underground workers for optimum preventive measures.

    We investigated the relative contribution of the queen and workers to colony nestmate recognition cues and on colony insularity in the Carpenter ant Camponotus fellah. Workers were either individually isolated, preventing contact with both queen and workers (colonial deprived, CD), kept in queenless groups, allowing only worker-worker interactions (queen deprived, QD) or in queenright (QR) groups. Two weeks post-separation QD and QR workers were amicable towards each other but both rejected their CD nestmates, which suggests that the queen does not measurably influence the colony recognition cues. By contrast, aggression between QD and QR workers from the same original colony was apparent only after six months of separation. This clearly demonstrates the power of the Gestalt and indicates that the queen is not a dominant contributor to the nestmate recognition cues in this species. Aggression between nestmates was correlated with a greater hydrocarbon (HC) profile divergence for CD than for QD and QR workers, supporting the importance of worker-worker interactions in maintaining the colony Gestalt odour. While the queen does not significantly influence nestmate recognition cues, she does influence colony insularity since within 3 days QD (queenless for six months) workers from different colony origins merged to form a single queenless colony. By contrast, the corresponding QR colonies maintained their territoriality and did not merge. The originally divergent cuticular and postpharyngeal gland HC profiles became congruent following the merger. Therefore, while workers supply and blend the recognition signal, the queen affects worker-worker interaction by reducing social motivation and tolerance of alien conspecifics.

    Full Text Available The issue of foreign workers has received increase media and national attention. However, to date there has been limited research on the nature and consequences of employment of foreign workers in Malaysia. Introduction of significant changes in recruitment phenomenon has ended in painful and traumatic atmosphere which barely acceptable by local workforce in Malaysia. This conceptual paper can be derived from the field of industrial relations which play a significant role in employment of foreign workers. The article reports on the preliminary findings on employment status of local workforce and trade union rights affected by employment of foreign workers. In addition, the research makes a number of recommendations, including the need for further development on reducing the employment of foreign workers and more refined targeting of vulnerable foreign workers linked with labor legislations.

    Presenteeism affects the performance of healthcare workers. This study examined associations between job stress, affective commitment, and presenteeism among healthcare workers. To investigate the relationship between job stress, affective commitment, and presenteeism, structural equation modeling was used to analyze a sample of 1392 healthcare workers from 11 Class A tertiary hospitals in eastern, central, and western China. The mediating effect of affective commitment on the association between job stress and presenteeism was examined with the Sobel test. Job stress was high and the level of presenteeism was moderate among healthcare workers. Challenge stress and hindrance stress were strongly correlated (β = 0.62; p stress was significantly positively correlated with affective commitment (β = 0.15; p stress was significantly inversely correlated with affective commitment (β = -0.40; p workers. Presenteeism can be addressed by increasing affective commitment and challenge stress and by limiting hindrance stress among healthcare workers in China.

    The purpose was to investigate the relationship between autonomy support by managers and co-workers and employees' work motivation and self-efficacy in two studies. In Study 1, a sample of 343 Swedish workers completed surveys, and in Study 2, we followed up with a subsample of 98 workers one year later. As in previous studies, managers support of autonomy was significantly positively related to workers' outcomes. However, the results of Study 1 also showed that co-worker autonomy support was related to these outcomes over and above the effects of manager support. Study 2 showed that changes in autonomy support from co-workers during one year significantly predicted motivation and self-efficacy one year later, while change in support from managers was unrelated to outcomes later. These findings provide evidence for the importance of both vertical and horizontal sources of support.

    2011-03-01

    Exposure to ionising radiation has been suggested as a causal risk factor for malignant pleural mesothelioma (MPM). Studies of patients treated by radiotherapy for primary cancers have suggested that radiation contributes to the development of secondary MPM. Here we examined the risk to nuclear workers of MPM related to exposure to low doses of occupational radiation at low dose rates. All results concerning MPM risk in published studies of nuclear workers were examined for their association with radiation exposure and potential confounders. We found 19 relevant studies. Elevated risks of pleural cancer were reported in most (15/17) of these studies. Eight reported risks higher for radiation monitored workers than for other workers. However, of 12 studies that looked at associations with ionising radiation, only one reported a significant dose-risk association. Asbestos was an important confounder in most studies. We conclude that studies of nuclear workers have not detected an association between ionising radiation exposure and MPM. Further investigations should improve the consideration of asbestos exposure at the same time as they address the risk of MPM related to occupational exposure of nuclear workers to low doses of ionising radiation at low dose rates.

    Objective:To determine the prevalence of malaria infections among foreign migrant workers in Thailand. Methods:Giemsa-stained thin and thick blood films were prepared from blood samples of294 foreign migrant workers recruited in the study. Microscopic examination of these blood films was performed for malaria detection.Results: Blood film examination revealed 1.36%malaria infections in these294 subjects. All positive cases were male Myanmar workers in which their blood films only ring stage ofPlasmodium spp. was found at low parasite density (mean=144parasites/μL of blood). The prevalence of malaria infections was not significantly different among foreign migrant workers classified by age, gender, and resident province (P>0.05). Thin blood films of these workers also showed78.91%hypochromic erythrocytes and 61.9%relative Eosinophilia.Conclusions:These findings indicate a high risk of malaria transmission. Therefore active malaria surveillance by using molecular methods with more sensitive and specific than microscopy should be considered for malaria control in foreign migrant workers.

    Full Text Available The objective of this study was to find out the prevalence, characteristics, and distribution of musculoskeletal pain among construction workers in Saudi Arabia. A questionnaire about musculoskeletal pain in different parts of the body was completed by 165 construction workers from the construction industries in Dammam and Riyadh cities. The descriptive data were analyzed using chi-square test. The level of statistical significance was set at P<0.05. Eighty (48.5% of the responding workers had pain in neck, shoulders, lower back, hand, knee, or ankle. The majority of respondents had low back pain (50% followed by knee pain (20%. The average intensity of pain at all sites during activity and rest was 6.65 and 3.59, respectively. Thirty-four (42.5% respondents had dull aching pain and 24 (30% had cramping pain. There was an association between years of experience, duration of break during work, and use of protective equipment with the prevalence of musculoskeletal pain in construction workers (P<0.05. Most of the workers complaining of pain got medical treatment (62.5% and only 25% received physical therapy. It can be concluded from this study that the prevalence of musculoskeletal pain among construction workers in Saudi Arabia is high.

    Workplace expectations reflect an important consideration in employee experience. A higher prevalence of workplace congruence between worker and employer expectations has been associated with higher levels of productivity and overall workplace satisfaction across multiple occupational groups. Little research has investigated the relationship between workplace congruence and occupational health outcomes among social service workers. This study sought to better understand the extent to which occupational congruence contributes to occupational outcomes by surveying unionised social service workers (n = 674) employed with the Government of Alberta, Canada. Multiple regression analysis shows that greater congruence between workplace and worker expectations around workloads, workplace values and the quality of the work environment significantly: (i) decreases symptoms related to distress and secondary traumatic stress; (ii) decreases intentions to leave; and (iii) increases overall life satisfaction. The findings provide some evidence of areas within the workplace of large government run social welfare programmes that can be better aligned to worker expectations to improve occupational outcomes among social service workers.

    Loveday Rachel

    2008-08-01

    Full Text Available Abstract Background There has been significant growth in the number of healthcare workers born outside the UK or recruited to the UK from countries with a high prevalence of TB, Hepatitis and other blood borne infections. Government policy recognises the need for occupational health procedures to facilitate treatment for these individuals and to reduce the risk of transmission of disease to patients. The aim of this study was to undertake a survey of nursing and residential homes in South East England, to assess whether homes had occupational health screening policies for healthcare workers who have originated from overseas, and what level of occupational health screening had been undertaken on these employees. Methods An anonymous survey was sent to all 500 homes in West Sussex assessing occupational health practices for "overseas health care workers", defined as health care workers who had been born outside the UK. Results Only one employer (0.8% reported they had an occupational health screening policy specific for healthcare workers who originate from overseas. Over 80% of homes who had recruited directly had no evidence of screening results for HIV, TB, Hepatitis B and C. The commonest countries of origin for staff were the UK, Philippines, Poland, South Africa, Zimbabwe, and India. Conclusion This study suggests that screening of overseas healthcare workers is not routine practice for residential or nursing care homes and requires further input from Primary Care Trust's, Health Care Commission, Commission for Social Care Inspection, and Professional bodies.

    2007-05-01

    Tuberculosis (TB) is a global emergency. Poverty, increasing migration, homelessness and the compulsions to live and work in high-risk environments are making people increasingly susceptible to the disease. Those working in mines, construction work, stone-crushing and in other similar occupations where there is a greater level of exposure to silica dust are specially vulnerable. Though the association between TB and silicosis has been firmly established by the results of epidemiologic studies no attempts have been made to study the epidemiological features of radiologically active TB among free silica exposed workers. Thus the cross sectional study was carried out among slate pencil workers and quartz stone crushers to assess the prevalence of TB and some associated epidemiological factors. It included 253 quartz workers and 102 slate pencil workers. Clinical history and chest radiographs were used for labeling the subjects as tuberculotic. The pulmonary functions of the subjects were measured using Spirovit SP- 10. Statistical analysis was carried out using statistical software package Epi Info 3.3.2. Among stone crushers the prevalence of TB was found to be 10.7% while among slate pencil workers it was as high as 22.5%. Among the quartz stone-crushers the workers aged ≥35 years, those exposed for ≥3 years and those who were smokers had higher risk TB while among the slate pencil workers, only those exposed for ≥10 years had higher risk. Though the FVC and FEV(1) values of the workers having TB were lower than those having normal radiographs, the differences were found to statistically non-significant.

    To study the effects of serum p21 levels on the health of coal tar pitch(CTP) and coke oven volatiles (COV) workers recognized as the high risk population of pulmonary carcinoma, serum p21 levels among 24 cases of CTP workers, 25 cases of COV workers and 12 cases of normal control were detected with the method of Western Blotting. The results showed that the mean serum p21 level in exposed group was significantly higher than that in the normal control (366.8 vs 1270.7, P < 0.001). In the COV workers, serum p21 level in coke furnace workers was remarkably higher than that in the workers with other types of work. There were no differences for p21 among workers with different work years and between workers with or without smoking history. It indicates that CTP and COV can cause the p21 protein level increase in the occupational population.

    Background According to the regulations of the Chinese and Shanghai governments, migrant workers employed in Shanghai should all be entitled to Shanghai Migrant Worker Hospitalization Insurance (SMWHI) without premium and the vast majority should also have the New Rural Cooperative Medical System (NRCMS). This study aimed to examine the status of the coverage and utilization of health insurance among migrant workers employed in Shanghai. Methods Quantitative and qualitative research methods were employed in the study. A survey of 1020 migrant workers employed in Shanghai was conducted in 2010 with a structured questionnaire. Focus group discussions were held with respondents who were unable to maintain health insurance coverage through NRCMS or SMWHI. In-depth interviews were held with village heads and employers of the migrant workers, migrant workers who were hospitalized within the last year, and various individuals employed by the insurance agencies. Results The study found that 72.9% and 36.5% of migrant workers were covered by NRCMS or SMWHI, respectively,while 16.7% of them had no health insurance. The coverage by NRCMS among migrant workers correlated significantly with education level and workplace, while the coverage by SMWHI correlated significantly with the length of employment in Shanghai and workplace. The qualitative results confirmed that migrant workers were the main group who were not covered by NRCMS, and the coverage by SMWHI was completely dependent upon the employers of the migrant worker.The results also showed that health insurance utilization among migrant workers was strongly limited by hospital location. Conclusions We observed that the status of health insurance among migrant workers was not accordant with theory,and that Chinese health insurance policy should be further reformed in order to realize full coverage and equal utilization of health insurance among migrant workers in China.

    This study was designed to compare the risk of occupational injuries in foreign workers compared to native workers in Taiwan. The cohort of foreign workers under study was constructed by records of legally registered workers migrated from foreign countries to Taiwan from July 1, 1991 to December 31, 1993. The native Taiwanese workers for comparison were labor-insured workers working in the same industries as foreign workers in 1992. The number of occupational injuries in the first year of employment were obtained by matching the cohort of foreign workers with the labor insurance payment records by name, birth date and passport number. The 1-year incidence rate of occupational injuries in the first year of employment was calculated and a standardized morbidity ratio (SMR) was used for comparison with adjustment for age distribution and to accommodate the small sample size of foreign workers. The risk to occupational injuries among total (SMR = 0.86) and male (SMR = 0.58) foreign workers was not higher; indeed, it was even lower, than that among native workers in Taiwan. However, the risk to female migrant workers, especially in the construction industry, was significantly higher than that of female Taiwanese workers (SMR = 1.60). Stratified by industry, the incidence was high in the fabricated metal products manufacturing industry and in machinery and equipment manufacturing industry for male foreign workers, while a high incidence for the female foreign workers occurred in construction industry and rubber products manufacturing industry. The risk of occupational injuries was greater for foreign workers who had been in Taiwan for only a short time. Most of the injuries occurred within the first 6 months of employment. Eighty-four out of the 394 occupational injuries among foreign workers resulted in disabilities. None of the accidents was fatal, but most of the disabilities were severe. The most common disabling injuries were cut or crushed fingers. The finding of a

    In the last two decades, service outsourcing has reduced companies' costs by the rationalization of their actions and the exploration of precarious work relations. This research aimed to outline the profile of outsourced workers in the cleaning service of a university hospital, identify their points of view about the health-illness process and future plans. This is a descriptive study from a quantitative approach, involving a random sample with 50 cleaning workers. Most of them started to work early, 74% were women and education level was low. In 36% of the cases, physicians diagnosed some kind of illness. In the analyzed period, 84% of the interviewees had realized medical consultations, resulting in an average of 3.6 consultations per worker, 56% of which involved general clinicians. Data analysis allowed for the identification of these professionals' perspectives in relation to the health/illness process and their future.

    The growth of the contingent workforce presents many challenges in the occupational safety and health arena. State and federal laws impose obligations and rights on employees and employers, but contingent work raises issues regarding responsibilities to maintain a safe workplace and difficulties in collecting and reporting data on injuries and illnesses. Contingent work may involve uncertainty about the length of employment, control over the labor process, degree of regulatory, or statutory protections, and access to benefits under workers' compensation. The paper highlights differences in regulatory protections and benefits among various types of contingent workers and how these different arrangements affect safety incentives. It discusses challenges caused by contingent work for accurate data reporting in existing injury and illness surveillance and benefit programs, differences between categories of contingent work in their coverage in various data sources, and opportunities for overcoming obstacles to effectively using workers' compensation data. © 2014 Wiley Periodicals, Inc.

    Full Text Available Introduction: Population monitoring and screening of blood pressure is an important part of any population health strategy. Qualified health workers are expensive and often unavailable for screening. Non-health workers with electronic blood pressure monitors are increasingly used in community-based research. This approach is unvalidated. In a poor, urban community we compared blood pressure measurements taken by non-health workers using electronic devices against qualified health workers using mercury sphygmomanometers. Method: Fifty-six adult volunteers participated in the research. Data were collected by five qualified health workers, and six non-health workers. Participants were randomly allocated to have their blood pressure measured on four consecutive occasions by alternating a qualified health worker with a non-health worker. Descriptive statistics and graphs, and mixed effects linear models to account for the repeated measurement were used in the analysis. Results: Blood pressure readings by non-health workers were more reliable than those taken by qualified health workers. There was no significant difference between the readings taken by qualified health workers and those taken by non-health workers for systolic blood pressure. Non-health workers were, on average, 5–7 mmHg lower in their measures of blood pressure than the qualified health workers (95%HPD: −2.9 to −10.0 for diastolic blood pressure. Conclusion: The results provide empirical evidence that supports the practice of non-health workers using electronic devices for BP measurement in community-based research and screening. Non-health workers recorded blood pressures that differed from qualified health workers by no more than 10 mmHg. The approach is promising, but more research is needed to establish the generalisability of the results.

    The Emergency Department (ED) is vulnerable for workplace violence, but little is known about this and its consequences. Objectives of this study were presence, characteristics and effects of violence from patients and visitors on health care workers in an Emergency Department (ED). This study was about the Accident and Emergency Department, S. Pertini Hospital, (ASL RMB, Rome, Italy). Data were collected from November 2014 to January 2015 on frequency and type of violent behavior in the past five years experienced by staff members and their level of stress by an ad hoc questionnaire for the evaluation of violent events in health activities (QVS) and a questionnaire on perceived work-related stress (QES). Of the 58 eligible workers, 51 completed the interview. Health care workers were regularly exposed to violence with a consequent severe underreporting to work authorities and only a minor reporting to the police. A diffuse belief that workplace violence is a normal part of the work was also identified. Aggressors were usually patients or their relatives and were mainly males. Health care workers may suffer physical and emotional harm. Emergency Department health care workers are at risk of experiencing workplace violence and should have specific training and support in the management of violent situations focused on early identification, communication strategies, and de-escalation techniques.

    The objective of this investigation was to determine the manner by which production standards or goals, performance or production feedback and monetary or wage incentive affected or moderated the relationship between worker satisfaction and productivity in a repetitive production task in a fishing industry. The industrial study was conducted to measure worker satisfaction and productivity under various experimental conditions involving production standards, performance feedback and monetary incentive. Only the participative standard and performance feedback condition affected the worker satisfaction-productivity relationship significantly for the fish-trimming task. The positive correlation coefficient (0.87) for this condition was found to be highly significant. This has an important implication for setting a strategy for achieving higher worker satisfaction and productivity in such an industry. Production standards with feedback generally improved worker satisfaction and productivity. Monetary incentive further improved worker performance but added no incremental satisfaction gain. The incorporation of production standards, performance feedback and monetary incentive affected worker satisfaction and productivity differently and this had an effect on the worker satisfaction-productivity relationship. In an earlier laboratory study, no significant worker satisfaction-productivity relationship was found when subjects (college students) were provided with similar experimental conditions.

    Background Honey bee (Apis mellifera) drones and workers show differences in morphology, physiology, and behavior. Because the functions of drones are more related to colony reproduction, and those of workers relate to both survival and reproduction, we hypothesize that the microclimate for worker brood is more precisely regulated than that of drone brood. Methodology/Principal Findings We assessed temperature and relative humidity (RH) inside honey bee colonies for both drone and worker brood throughout the three-stage development period, using digital HOBO® Data Loggers. The major findings of this study are that 1) both drone and worker castes show the highest temperature for eggs, followed by larvae and then pupae; 2) temperature in drones are maintained at higher precision (smaller variance) in drone eggs and larvae, but at a lower precision in pupae than the corresponding stages of workers; 3) RH regulation showed higher variance in drone than workers across all brood stages; and 4) RH regulation seems largely due to regulation by workers, as the contribution from empty honey combs are much smaller compared to that from adult workers. Conclusions/Significance We conclude that honey bee colonies maintain both temperature and humidity actively; that the microclimate for sealed drone brood is less precisely regulated than worker brood; and that combs with honey contribute very little to the increase of RH in honey bee colonies. These findings increase our understanding of microclimate regulation in honey bees and may have implications for beekeeping practices. PMID:26882104

    Cleanroom air is extremely dry, as it is maintained within 1 % of relative humidity. Few studies have assessed the dermatologic life quality of workers in ultralow-humidity environments. Therefore, we aimed to evaluate the dermatologic life quality of cleanroom workers using the Skindex-29, compared to those of non-cleanroom workers. Study participants were 501 cleanroom workers and 157 non-cleanroom workers from a secondary battery factory, who underwent an employee health examination at a single university hospital from September 2014 to September 2015. Results of the self-administered Skindex-29, and McMonnies questionnaire were analyzed. Other information and disease history were also collected during physician's medical examination. Descriptive and multivariate logistic regression analysis were performed. The Skindex-29 score was significantly higher in cleanroom workers than in non-cleanroom workers for all domains, Symptom (16.0 ± 15.9 vs. 6.3 ± 10.2, p factory is shown to be lower than that among non-cleanroom workers in this study. The study suggests that the Skindex-29 may provide helpful information on the dermatologic life quality of cleanroom workers. Therefore, regarding evaluation of dermatologic life quality using Skindex-29, preventive care is necessary for cleanroom workers in ultralow humidity environment.

    A cohort of 8854 men, 2293 of whom were exposed to acrylamide, was examined from 1925 to 1983 for mortality. This cohort consisted of four plant populations in two countries: the United States and The Netherlands. No statistically significant excess of all-cause or cause-specific mortality was found among acrylamide workers. Analysis by acrylamide exposure levels showed no trend of increased risk of mortality from several cancer sites. These results do not support the hypothesis that acrylamide is a human carcinogen.

    The aim of the study is to evaluate whether occupational exposure to night work could cause alterations in the levels of plasmatic cortisol. The interest toward this argument arises form several studies in scientific literature referring the presence of an alteration in the synthesis and release of cortisol in workers exposed to night work. We studied a population of workers employed in night security service and monitoring service of alarm systems in different museums compared to a control group not performing shift-work and/or night work. The exposed and control subjects were compared by age, length of service, smoking habit (n. cigarettes per day), habitual consumption of alcoholic drinks (n. glass of wine/beer per day). We evaluated the levels of plasmatic cortisol on 50 workers exposed to night work, all males of whom 30 smokers and 20 non-smokers and on 50 controls of whom 30 smokers and 20 non-smokers.

    Full Text Available Abstract Background The objective of our study was to describe factors associated with repeat workers' compensation claims and to compare the work disability arising in workers with single and multiple compensation claims. Methods All initial injury claims lodged by persons of working age during a five year period (1996 to 2000 and any repeat claims were extracted from workers' compensation administrative data in the state of Victoria, Australia. Groups of workers with single and multiple claims were identified. Descriptive analysis of claims by affliction, bodily location, industry segment, occupation, employer and workplace was undertaken. Survival analysis determined the impact of these variables on the time between the claims. The economic impact and duration of work incapacity associated with initial and repeat claims was compared between groups. Results 37% of persons with an initial claim lodged a second claim. This group contained a significantly greater proportion of males, were younger and more likely to be employed in manual occupations and high-risk industries than those with single claims. 78% of repeat claims were for a second injury. Duration between the claims was shortest when the working conditions had not changed. The initial claims of repeat claimants resulted in significantly (p lower costs and work disability than the repeat claims. Conclusions A substantial proportion of injured workers experience a second occupational injury or disease. These workers pose a greater economic burden than those with single claims, and also experience a substantially greater cumulative period of work disability. There is potential to reduce the social, health and economic burden of workplace injury by enacting prevention programs targeted at these workers.

    A cross-sectional study was performed at a plant in which 99 workers were employed in the manufacture of oriented strand board. This group was compared with 165 unexposed workers from the petroleum industry. Both groups were assessed, using a questionnaire, spirometry, and skin prick tests to common environmental antigens. Environmental studies showed a low dust level of 0.27 mg/m3, consisting of particles of a mass median aerodynamic equivalent diameter of 2.5 microns. There were variable concentrations of formaldehyde, up to 0.27 ppm. A significant difference between the oriented strand board workers and oil field workers was noted for the forced expiratory volume in 1 s/forced vital capacity ratio, without significant differences in either the forced expiratory volume in 1 s or the forced vital capacity. Oriented strand board workers who were current smokers were three times as likely to have a forced expiratory volume in 1 s/forced vital capacity ratio of less than 75% of that found in the currently smoking oil field workers. Significant reductions in forced expiratory volume in 1 s (p = .044) and forced vital capacity (p = .022) in oriented strand board workers were noted across the work shift. The oriented strand board workers complained of self-reported asthma and of lower respiratory tract symptoms significantly more frequently than did oil workers for all of the symptoms examined. The prevalence of atopy was not different in the two groups. Lung function was significantly better in oriented strand board workers who had no symptoms, compared with oriented strand board workers who were symptomatic.(ABSTRACT TRUNCATED AT 250 WORDS)

    Vinyl chloride monomer (VCM) is widely used in the production of polyvinyl chloride (PVC) plastics. VCM is recognized as a confirmed human and animal carcinogenic compound. Recent studies have reported poor health of plastic workers, even having exposure at concentrations below the permissible limit to VCM. There has not been any study regarding exposed workers to VCM in Iran. Similarly, no information exists as to the biological monitoring of such workers. The main purpose of this study was to conduct a thorough occupational and biological monitoring of Iranian plastic workers exposed to VCM.A total of 100 workers from two plastic manufacturing plants (A and B) in Tehran along with 25 unexposed workers as controls were studied. The personal monitoring of all nonsmoking workers exposed to VCM at two plastic manufacturing plants (A and B) was performed in the morning shift (8 a.m. to 4 p.m.) according to the National Institute For Occupational Safety And Health method no. 1007.Biological monitoring of workers was carried out through collection of exhaled breath of all exposed and control workers in Tedlar bags and with a subsequent analysis using gas chromatography-flame ionization detector.Not only the mean occupational exposure of workers to VCM at plant A was higher than the respective threshold limit value but also the statistical significance was higher than workers at plant B. Similarly, VCM concentration in exhaled breath of workers at plant A was also statistically significantly higher than at plant B. Correlation of occupational exposure of all workers to vinyl chloride with its concentration in exhaled breath was statistically significant.This is the first study on biological monitoring for exposed plastic workers to VCM using exhaled breath. On the basis of the results in this study, a novel method of biological monitoring of plastic workers was proposed.

    Construction workers were and are considered temporary workers at many construction sites. Since World War II, large numbers of construction workers were employed at U.S. Department of Energy nuclear weapons sites for periods ranging from a few days to over 30 years. These workers performed tasks during new construction and maintenance, repair, renovation, and demolition of existing facilities. Such tasks may involve emergency situations, and may entail opportunities for significant radiation exposures. This paper provides data from interviews with more than 750 construction workers at two gaseous diffusion plants (GDPs) at Paducah, Kentucky, and Portsmouth, Ohio regarding radiation monitoring practices. The aim was to determine the extent to which workers believed they were monitored during tasks involving potential radiation exposures. The adequacy of monitoring practices is important for two reasons: (a) Protecting workers from exposures: Construction workers were employed by sub-contractors, and may frequently been excluded from safety and health programs provided to permanent employees; and (b) Supporting claims for compensation: The Energy Employees Occupational Illness Compensation Program Act (EEOICPA) requires dose reconstruction of radiation exposures for most workers who file a claim regarding cancer. The use of monitoring data for radiation to qualify a worker means that there should be valid and complete monitoring during the work time at the various nuclear plants or workers may be unfairly denied compensation. The worker interviews from Paducah and Portsmouth were considered especially useful because these sites were designated as Special Exposure Cohorts (SECs) and the workers did not have to have a dose reconstruction to qualify for compensation for most cancers. Therefore, their responses were less likely to be affected by compensation concerns. Interview questions included asking for information regarding whether monitoring was performed, how

    Chest roentgenograms of 240 perlite workers employed for 1 to 23 years in the industry, showed no evidence of pneumoconiosis associated with perlite exposures. One individual, found to have simple pneumoconiosis, and one found to have complicated pneumoconiosis, had formerly been diatomaceous earth workers. Since only 28 of the men had been in the industry over 15 years and only seven for 20 years or more, continued surveillance is essential to make sure that there are no effects with more prolonged exposures. Studies of pulmonary function of the individuals who have had relatively long exposures are needed to supplement radiographic evidence.

    To compare chronic respiratory symptoms, fractional exhaled nitric oxide (FENO), and lung function between Robusta and Arabica coffee workers and a control group. Chronic respiratory symptoms were assessed by a questionnaire (n = 138 coffee workers and n = 120 controls). The FENO was measured by NIOX MINO device (Aerocrine AB, Solna, Sweden). Lung function was examined by a portable spirometer. Coffee workers had higher prevalence of chronic respiratory and asthma symptoms than controls. Robusta coffee workers were exposed to higher levels of endotoxin and had more asthma symptoms than Arabica coffee workers (38% vs. 18%). Coffee workers had reduced lung function associated with cumulative exposure to total dust and endotoxin. Work in coffee factories is associated with small but significant lung function impairment. These changes were not associated with the level of FENO.

    Although significant differences in values between social workers and clients are widely understood to affect the efficacy of service provision, no studies have sought to examine how the values affirmed by social workers may differ from those held by members of the working and middle classes. Therefore, this study examines the degree of value similarity between social workers and consumers. Based on "new-class" theory, two hypotheses are proposed. First, graduate social workers affirm value positions to the left of working- and middle-class clients. Second, bachelor's-level social workers affirm value positions in between those of graduate workers and clients. Both hypotheses were supported. The implications for the divergence in value frameworks for advocacy, practice, and education are discussed.

    Eighteen percent of drivers do not consistently wear their seatbelts when driving. The purpose of this article is to report the problem of noncompliance with seatbelt use among health care workers at a Level I pediatric trauma center in the midwest United States with evidence from a non-experimental, observational study. Results showed that 84% (n=3,641) of drivers and 73% (n=113) of passengers wore their seatbelts. A significant correlation was found between driver seatbelt use and passenger seatbelt use (p=.272, p<.001). Drivers from primary seatbelt legislation states wore their seatbelts significantly more often than drivers from the secondary seatbelt legislation state, χ(1)=0.913, p=.012. Non-compliance with seatbelt use among pediatric health care workers is a problem equal to that of the general population. It may be necessary to adopt and enforce mandatory seatbelt use policies at the organizational level to increase seatbelt use in this population of hospital workers.

    This research analyzed the extent to which self-reports of job-related discrimination by persons with serious mental illness are associated with econometric measures of discrimination. Data were from the 1994-1995 National Health Interview Survey-Disability Supplement. Data for workers with mood, psychotic, or anxiety disorders (N=1,139) were compared with data for those without such disorders (N=66,341). The main outcome measures were self-reports of wages and stigmatizing experiences in the workplace. After the analyses controlled for functional limitations and job characteristics, no significant difference in mean wages was found between workers with serious mental illness who did not report experiencing stigma and those with no mental illness. In contrast, for all types of mental disorders examined, mean wages for workers with serious mental illness who reported experiencing stigma were significantly lower than mean wages for those with no mental illness. Workers' self-reports of stigmatizing experiences in the labor market appear to be consistent with econometric measures of the effect of stigma on wages, suggesting that workers know when they are being discriminated against.

  7. Worker Attitudes towards Mental Health Problems and Disclosure

    2014-09-01

    Full Text Available Background: There is a significant proportion of workers with mental disorders who either are struggling at work or who are trying to return to work from a disability leave. Objective: Using a population-based survey of working adults in Ontario, Canada, this paper examines the perceptions of workers towards mental disorders in the workplace. Methods: Data are from a sample of 2219 working adults identified through random digit dialing who either completed a telephone questionnaire administered by professional interviewers or a web-based survey. Results: A third of workers would not tell their managers if they experienced mental health problems. Rather than a single factor, workers more often identified a combination of factors that would encourage disclosure to their managers. One of the most identified disincentives was the fear of damaging their careers. The most pervasive reasons for concerns about a colleague with a mental health problem included safety and the colleague's reliability. Conclusion: Although critical for workers who experience a mental disorder and who find work challenging, a significant proportion do not seek support. One barrier is fear of negative repercussions. Organizations' policies can create safe environments and the provision of resources and training to managers that enable them to implement them. By making disclosure safe, stigma and the burden of mental disorders in the workplace can be decreased.

    The training of health workers in breastfeeding and lactation management is to enable them make correct breastfeeding recommendations to mothers. This study aims to provide answers to two research questions: what components of breastfeeding training are easily achieved with extension health workers, and what health worker variables affect these outcomes. Multivariable analysis of the outcomes of a controlled breastfeeding training programme for community health workers (CHW) in rural communities of Osun State, Nigeria, was performed by logistic regression. The results show that the training was the most powerful predictor of correct CHW recommendations on breastfeeding (OR = 60.25, p-0.0000), and of 'perfect' breastfeeding knowledge (OR = 192.49, p = 0.0000). Younger CHWs (in the age bracket 20 to 29 years) were significantly more likely to make correct recommendations on exclusive breastfeeding (OR = 3.02, p = 0.0304). Other CHW variables such as sex, experience, job status, and marital status did not make consistently significant independent contributions to the outcomes. The results suggest that breastfeeding education can enhance CHW professional recommendations on breastfeeding and should be extended to all categories of health workers.

    Nonreproductive workers of many eusocial Hymenoptera 'police' the colony, that is, they attack reproductive sister workers or destroy their eggs (unfertilized; developing into haploid males). Several ultimate causes of policing have been proposed, including (1) an increase in colony productivity,...... reproductive workers. We infer that relatedness incentives are the most likely ultimate cause of the evolutionary maintenance of worker-egg policing in A. echinatior.

    1982-02-01

    Medical consultation rates were compared between a group of lead workers (346 males) and two groups of non-lead workers (317 and 329 males) in a newspaper company where a serious industrial dispute took place over health effects of lead three years before this study. The comparison was also made within the group of lead workers. Maximal blood lead concentrations (PbBs) ranged from 0.1 mumol/kg to 3.6 mumol/kg (74 microgram/100 g) with an average of 1.3 mumol/kg in the past three years. Ages averaged 35 years in lead workers, and 34 and 30 years in non-lead workers, the ranges being 19-55 years in all. The consultation rate of lead workers was significantly higher than that of both the non-lead workers (P less than 0.001), when the number of workers who consulted physicians or dentists once or more for a year per 100 workers (general consultation rate) was compared. Disease-specific consultation rates were also higher in lead workers for seven categories of diseases and injuries such as hypertensive disease and peptic ulcers. When lead workers were divided into three groups by PbB or erythrocytes delta-aminolevulinic acid dehydratase (ALAD) levels, however, no significantly high rate was found in the higher PhB groups not lower ALAD groups in terms of general and disease-specific consultation rates. It was concluded that the industrial dispute might have been a major cause of the high consultation rate of lead workers.

    The experience rates of eighteen life events of Japanese workers were surveyed and the strength of each of the events was evaluated by a self-reported questionnaire. The fifteen professions surveyed included construction, transport, mailing, chemical production, banking, newspaper, TV services, commercial publishing, advertising, teaching and civil service. The number of workers who answered was 18,657 males and 4,443 females, aged 20 to 59 years. The male workers were divided and analysed in six job groups: clerical workers (n = 5,866), professionals (n = 3,696), blue collar day workers (n = 1,623), blue collar night or shift workers (n = 3,191), drivers (n = 1,663) and construction workers (n = 2,466). They were divided into groups and compared according to job, sex and five different age groups. The highest experience rate in each of the life events such as family trouble for both sexes, death of a family member, financial trouble and anxiety, death of a close friend, dissatisfactory transport to workplace or job, respectively. Comparing the experience rates between males and females we found no significant difference for five items. However, other items had higher experience rates for males than for females with the exception of family trouble. In regard to the age characteristics of each of the life events, as the age increased the experience rates of health-related life events such as the death of a spouse, child, family member or close friend and one's own illness or injury became higher. In contrast, the experience rates of items such as moving to a worse residence and failure in a school or training program became lower as the age increased for both sexes. Among job groups, construction workers had the highest experience rates of most life events except for the item of dissatisfactory transport to the workplace or job. Among other job groups, drivers had higher experience rates in the following four items: re-employment, death of spouse, divorce and

    Full Text Available Abstract Background Because of their peculiar sociocultural background, healthcare workers in sub-Saharan African subcultures may have various conceptions on different aspects of autism spectrum disorders (ASD, such as etiology, treatment and issues of prognosis. These various conceptions, if different from current knowledge in literature about ASD, may negatively influence help-seeking behavior of parents of children with ASD who seek advice and information from the healthcare workers. This study assessed the opinions of healthcare workers in Nigeria on aspects of etiology, treatability and preventability of childhood autism, and relates their opinions to the sociodemographic variables. Methods Healthcare workers working in four tertiary healthcare facilities located in the south-east and south-south regions of Nigeria were interviewed with a sociodemographic questionnaire, personal opinion on etiology, treatability and preventability of childhood autism (POETPCA questionnaire and knowledge about childhood autism among health workers (KCAHW questionnaire to assess their knowledge and opinions on various aspects of childhood autism. Results A total of 134 healthcare workers participated in the study. In all, 78 (58.2%, 19 (14.2% and 36 (26.9% of the healthcare workers were of the opinion that the etiology of childhood autism can be explained by natural, preternatural and supernatural causes, respectively. One (0.7% of the healthcare workers was unsure of the explanation of the etiology. Knowledge about childhood autism as measured by scores on the KCAHW questionnaire was the only factor significantly associated with the opinions of the healthcare workers on etiology of childhood autism. In all, 73 (54.5% and 43 (32.1%, of the healthcare workers subscribed to the opinion that childhood autism is treatable and preventable respectively. Previous involvement with managing children with ASD significantly influenced the opinion of the healthcare

    Mzungu, M

    1999-03-01

    This article exposes the conditions among children who are forced by their poor families to assume domestic work in households in Kenya. It is an accepted practice for parents to place daughters in households to help with housework and baby-sitting. The Sinaga Women and Child Labor Resource Center in Nairobi finds this exploitative and part of a wider practice that institutionalizes violence against women. The Center was established in 1995 to challenge the practice of child domestic labor. The Center's research reveals that child domestic workers tend to come from large, poor, and rural families or from urban slums. Wages are low or exchanged for shoes, clothes, and food. The hours of work are long. Mistreatment may include sexual molestation by male household members, beatings, verbal abuse, and mistrust. There is little recourse. Complaints from child workers or others outside the household can result in further mistreatment. Action against mistreatment is complicated by the prevailing image of activists as frustrated women with vendettas against men. The Center focuses on rehabilitation, literacy training, marketable skill development, and awareness creation. Counseling includes parents, children, and employers. Public awareness campaigns have resulted in employer referrals of youth workers for training. Other groups are joining the effort to improve conditions for child domestic workers.

    Full Text Available Background: Agate is a hard silica stone with bands of various colors, which is used in jewelry. The agate grinding workers are exposed to silica dust.Objective: To determine the prevalence of respiratory diseases in agate grinding workers and the associated factors.Methods: In this cross-sectional study, 170 agate grinding workers from Mashhad, northeastern Iran, were examined. Medical and occupational history for respiratory illnesses was taken using respiratory questionnaire of the national program of silicosis control, lung examination, spirometry and chest radiography. Chest x-rays were interpreted according to the International Labor Office (ILO classification system, 2000.Results: The mean±SD of age and work duration of the participants were 31.2±10.1 and 13±8.2 years, respectively. The prevalence of silicosis among agate workers was 12.9% (95% CI: 7.9%–18.0%; 18 workers had simple and 4 had complicated silicosis. There was a significant (p<0.05 relationship between contracting silicosis and exposure duration. 20 (11.7% workers had symptoms consistent with chronic bronchitis and 8 (4.7% showed asthma and asthma-like symptoms. The most frequent disorder observed in spirometry was the restrictive pattern (n=43, 30%. In the agate grinders, clinical and spirometry findings did not match with radiological findings.Conclusion: Agate grinding workers are at increased risk for respiratory diseases, specifically for silicosis and chronic bronchitis. The disease is related to silica dust exposure, poor ventilation and inappropriate personal protection.

    A total of 524 industrial workers were studied. They consisted of 442 noise exposed and 82 non-noise exposed workers. The purpose was to compare the prevalence of sensori-neural hearing loss among the noise exposed and the non-noise exposed workers, to study their knowledge on the hazard of noise to hearing and the workers' attitude towards the hearing protection devices. The prevalence of sensori-neural hearing loss was significantly higher among the noise exposed workers, i.e., 83% versus 31.7% (p workers, only 5.1% were wearing them regularly. The possibility of developing hearing loss due to exposure to excessive noise was only known by 35.5% of the noise exposed workers. This awareness was found to have a positive correlation with the workers' compliance to the hearing protection devices. Our findings highlight the need for workers to be educated on the hazards of excessive noise exposure to hearing.

    This study updates an earlier investigation that found a sixfold excess incidence of colorectal cancer among polypropylene workers for the period January 1960 to September 1985. The study cohort comprised 412 male workers with at least 6 months employment and 10 years latency. For the extended follow-up period (October 1985 to May 1992), the standardized incidence ratio (SIR) based on state comparison rates was slightly elevated and not statistically significant (SIR = 1.5, 95% confidence interval [CI] = 0.5 to 3.5). A 2.3-fold excess was observed among process workers (95% CI = 0.3 to 8.2), but this was based on only two cases. Risk among process/mechanical workers was greater for short-term workers ( or = 10 years, SIR = 0.7, 95% CI = 0.02 to 4.0). Overall, the update findings do not suggest an occupationally related risk. Possible influences of company-sponsored colorectal cancer screening, the polyolefin unit shutdown, and other factors are discussed.

Aim: This study was undertaken to provide epidemiological data regarding various dermatoses among migrant construction workers in India as currently there is a paucity of the same. Methods: One thousand construction workers, including 467 migrant laborers, were examined for various dermatoses. Results: Most (88% workers were males and 51.17% were in their third decade. Infective and noninfective dermatoses were seen in 89.72% and 53.74% of laborers respectively. Among infective dermatoses, fungal infections were the most common (46.25% ones, followed by bacterial infections (24.83%, scabies (8.56% and viral infections (6.42%. Contact dermatitis to cement was seen in 12.48% of the laborers. Masons had a significantly higher incidence of contact dermatitis to cement, viral infections and scabies than helpers. Conclusions: The pattern of dermatoses is an expression of poverty, overcrowding and the occupational hazards of the construction industry.

    Dominance hierarchy among animals is widespread in various species and believed to serve to regulate resource allocation within an animal group. Unlike small groups, however, detection and quantification of linear hierarchy in large groups of animals are a difficult task. Here, we analyse aggression-based dominance hierarchies formed by worker ants in Diacamma sp. as large directed networks. We show that the observed dominance networks are perfect or approximate directed acyclic graphs, which are consistent with perfect linear hierarchy. The observed networks are also sparse and random but significantly different from networks generated through thinning of the perfect linear tournament (i.e. all individuals are linearly ranked and dominance relationship exists between every pair of individuals). These results pertain to global structure of the networks, which contrasts with the previous studies inspecting frequencies of different types of triads. In addition, the distribution of the out-degree (i.e. number of workers that the focal worker attacks), not in-degree (i.e. number of workers that attack the focal worker), of each observed network is right-skewed. Those having excessively large out-degrees are located near the top, but not the top, of the hierarchy. We also discuss evolutionary implications of the discovered properties of dominance networks. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

    Worker Protection Standard (WPS) training is one of the U.S. Environmental Protection Agency's (EPA) primary methods for preventing pesticide exposure in agricultural workers. Retention of the knowledge from the training may occasionally be tested by state Occupational Safety and Health Administrations (state OSHAs) during a site visit, but anecdotal evidence suggests that there is no consistent testing of knowledge after WPS training. EPA's retraining requirements are at 5-year intervals, meaning the knowledge must be retained for that long. Vineyard workers completed a test of their baseline WPS knowledge, computer-based training on WPS, a post-test immediately after training and a re-test 5 months later. Pre-test performance suggested that there was a relatively high level of baseline knowledge of WPS information on two-answer multiple choice tests (74% to 75%) prior to training. Training increased the knowledge to 85% on the post-test with the same questions, a significant increase (p WPS information may be the most important impact of training.

    Significant environmental benefits are claimed for local food systems, but these biophysical indicators are increasingly recognised as inadequate descriptors of supply chain ethics. Social factors such as health are also important indicators of good practice, and are recognised by the organic and local food movements as important to the development of rounded sustainable agricultural practices. This study compared the self-reported health status of farm workers in the United Kingdom, Spain, Kenya and Uganda who were supplying distant markets with fresh vegetables. Workers on Kenyan export horticulture farms reported significantly higher levels of physical health than did Kenyan non-export farm workers and workers in the other study countries. Mean health levels for farm workers in the United Kingdom were significantly lower than relevant population norms, indicating widespread levels of poor health amongst these workers. These results suggest that globalised supply chains can provide social benefits to workers, while local food systems do not always provide desirable social outcomes. The causal mechanisms of these observations probably relate more to the social conditions of workers than directly to income.

The study was designed to evaluate the effect of training on the knowledge, attitudes and provision of infant and young child feeding (IYCF information and counselling among primary healthcare (PHC workers. Methods: A two-stage cluster sample was used to select health workers for training on IYCF in Ibadan, Nigeria. Baseline, immediate and 4-week post-training surveys were conducted to assess knowledge, attitudes and practices of health workers regarding IYCF. Paired t-tests were used to measure differences (p < 0.05 before and after the training. Results: A total of 124 health workers were trained on current global IYCF recommendations. Participants included community health extension workers (59.7%, nurses (27.4%, community health officers (11.3%, and pharmacy technicians (1.6%. Mean age was 41.8 ± 8.2 years and 95.2% were women. Knowledge of health workers regarding IYCF, particularly complementary feeding, was low at baseline but improved significantly following the training intervention. Attitudes and practices regarding provision of IYCF were suboptimal among health workers at the PHC facilities, but this improved with training. Conclusion: Health workers at the PHC level need regular retraining exercises to ensure effective counselling on IYCF.

  12. Size determines antennal sensitivity and behavioral threshold to odors in bumblebee workers

    The eusocial bumblebees exhibit pronounced size variation among workers of the same colony. Differently sized workers engage in different tasks (alloethism); large individuals are found to have a higher probability to leave the colony and search for food, whereas small workers tend to stay inside the nest and attend to nest duties. We investigated the effect of size variation on morphology and physiology of the peripheral olfactory system and the behavioral response thresholds to odors in workers of Bombus terrestris. Number and density of olfactory sensilla on the antennae correlate significantly with worker size. Consistent with these morphological changes, we found that antennal sensitivity to odors increases with body size. Antennae of large individuals show higher electroantennogram responses to a given odor concentration than those of smaller nestmates. This finding indicates that large antennae exhibit an increased capability to catch odor molecules and thus are more sensitive to odors than small antennae. We confirmed this prediction in a dual choice behavioral experiment showing that large workers indeed are able to respond correctly to much lower odor concentrations than small workers. Learning performance in these experiments did not differ between small and large bumblebees. Our results clearly show that, in the social bumblebees, variation in olfactory sensilla number due to size differences among workers strongly affects individual odor sensitivity. We speculate that superior odor sensitivity of large workers has favored size-related division of labor in bumblebee colonies.

    Full Text Available Background : Automobile repair shop is a place where workers are exposed to harmful chemicals and toxic substances. Objective : To study the occurrence of obstructive and restrictive pulmonary impairment among automobile garage workers. Methods : A cross sectional study involving 151 automobile garage workers from 14 randomly selected garages of urban Kolkata. The study variables were Forced Expiratory Volume in 1 second (FEV 1 , Forced Vital Capacity (FVC, Peak Expiratory Flow Rate (PE FR, age, smoking habit, duration of work, type of work, and respiratory symptoms. The study was analysed using Regression equations, and Chi-square test. Results : All the workers were male. Obstructive impairment was seen in 25.83% of the workers whereas restrictive impairment was seen in 21.19% of the workers. Mixed obstructive and restrictive impairment was seen in 10.6% of the workers. The frequency of obstructive impairment was higher in older workers. In the age group of less than 20 years, 13.6% of the workers had obstructive impairment while 42.86% of workers above 40 years of age had obstructive impairment. Obstructive impairment was more frequently observed in battery repair workers (58.33% and spray painters (37.5% while 16.67% of the body repair workers and 30.19% of the engine mechanics had obstructive impairment. Obstructive impairment was more frequently observed in smokers (53.1 % as compared to ex-smokers (33.3% and non-smokers (6.4%. Obstructive impairment was more frequently observed in workers who had been working for a longer duration. Conclusion: Nearly 36.4% of the automobile garage workers had some form of pulmonary function impairment; obstructive and/or restrictive. The use of personal protective equipment, worker education, and discontinuation of the use of paints containing toxic pigments are recommended.

    The purpose of this paper is to apply a stress model drawn from the literature to the relief and social service workers who have been active in refugee camps for a prolonged period of time. Working in difficult environments, social service workers deliver essential services to refugee populations around the world. A model of four work-stress determinants--tasks, management, appreciation and collaboration--was tested on 274 social workers in five regions of the Middle East (Jordan, Lebanon and Syria, as well as the occupied Palestinian territories of the Gaza Strip and the West Bank). Statistical fit indices were adequate but two relationships were statistically insignificant. The collaboration variable was dropped to create a modified model with tasks indirectly and management and appreciation directly affecting work-related stress. The five direct relationships and two indirect relationships of this modified model are consistent with stress theory, and all relationships--direct and indirect--are statistically significant.

    Silver has long been valued as a precious metal, and it is used to make ornaments, jewelry, high-value tableware, utensils, and currency coins. Human exposures to silver and silver compounds can occur oral, dermal, or by inhalation. In this study, we investigated genotoxic and oxidative effects of silver exposure among silver jewelry workers. DNA damage in peripheral mononuclear leukocytes was measured by using the comet assay. Serum total antioxidative status (TAS), total oxidative status (TOS), total thiol contents, and ceruloplasmin levels were measured by using colorimetric methods among silver jewelry workers. Moreover, oxidative stress index (OSI) was calculated. Results were compared with non-exposed healthy subjects. The mean values of mononuclear leukocyte DNA damage were significantly higher than control subjects (p jewelry workers caused oxidative stress and accumulation of severe DNA damage.

    To report health outcomes of 30 years (1978-2007) of medical surveillance of workers engaged in a perfluooctanoic acid (PFOA) production plant. Fifty-three males workers (20 to 63 years) were submitted every year to medical examination and blood chemical chemistry tests, and serum PFOA dosage. In the latest survey PFOA serum levels ranged from 0.20 to 47.04 microg/mL in currently exposed workers, and from 0.53 to 18.66 microg/mL in those formerly exposed. No clinical evidence of any specific trouble or disease has been recorded over the 30 years, and all the biochemical parameters, including liver, kidney and hormonal functions, turned out to be within the reference ranges, but a significant association of total cholesterol and uric acid with and PFOA serum level was evidenced. A probable interference of PFOA on intermediate metabolism deserves further investigations.

    Serum vitamin B12, folic acid, ferritin and haematological variables were investigated in eighty-seven male and nineteen female construction site workers in Bangkok. Haemoglobin concentration, haematocrit and MCHC were found to be higher in male than in female workers. Serum ferritin was slightly higher in males than in females. Serum B12 was found to be higher in male than in female workers and serum folic acid level were significantly higher in female than in male workers. Vitamin B12 deficiency was found in 2.3 per cent and folic acid deficiency in 6.9 per cent of the male workers. Serum vitamin B12 and folic acid levels were normal for female workers. The adequate serum levels of vitamin B12 and folic acid might be the result of the habit of the workers to consume tonic drinks which contain glucose, caffeine, and vitamins especially vitamins B6, and B12.

It bases on the experiences of one of the authors, and on preliminary results of qualitative and quantitative research gathered from 300 software engineers working in the IT financial service sector in Poland. It reviews main approaches to software specialist motivation found in the scientific and practical literature. It critiques some approaches to motivation of software specialists for the long-term consequences of using the motivators that they focus on. It shows that research based on P. Glen’s model (2003a analyses only hygienic factors (as described by Herzberg that can hinder the state of flow (Csikszentmihalyi 1975, which is characteristic of internally motivated software specialists. There are no analyses which would show how to secure long-term hygienic factors in the management of IT specialist motivation. Recommendations on long-term hygienic factors form a significant part of the text.

    This study explored knowledge, attitudes and practices towards HIV/AIDS infection among 1256 Egyptian industrial and tourism workers aged 16-40 years. Compared with industrial workers, tourism workers had a significantly better perception of the magnitude of the HIV/AIDS problem worldwide as well as in Egypt and of the likelihood of the problem worsening. Knowledge of tourism workers was also significantly better about causative agent of AIDS and methods of transmission. Both groups had negative attitudes towards patients living with HIV/AIDS concerning their right to confidentiality and to work. Both groups had a positive attitude towards behaviour change for protection from HIV/AIDS, principally via avoidance of extramarital sexual relations and adherence to religious beliefs. Use of condoms as a way to avoid HIV/AIDS was reported by only 0.4% of workers.

    Dyes are known to be a causative agent of occupational asthma exposed to them. We evaluate respiratory symptoms among textile. The study population comprised 106 exposed workers and control (unexposed) group. Data were collected by a questionnaire. Pulmonary Function Tests (PFTs) were performed. Among the exposed workers 36.8% defined phlegm. Respiratory symptoms were not significantly different between two groups. The employment duration of the exposed workers with phlegm was longer than those without phlegm (p = 0.027). The mean % predicted of forced expiratory flow (FEF) 25-75 of the exposed workers was found to be significantly lower than the control (unexposed) group (p = 0.01). Our study suggests that textile dyeing might cause respiratory symptoms at workers.

    1980-11-01

    The radiation risks to the health of workers who will construct and maintain solar power satellites in the space environment were examined. For ionizing radiation, the major concern will be late or delayed health effects, particularly the increased risk of radiation-induced cancer. The estimated lifetime risk for cancer is 0.8 to 5.0 excess deaths per 10,000 workers per rad of exposure. Thus, for example, in 10,000 workers who completed ten missions with an exposure of 40 rem per mission, 320 to 2000 additional deaths in excess of the 1640 deaths from normally occurring cancer, would be expected. These estimates would indicate a 20 to 120% increase in cancer deaths in the worker-population. The wide range in these estimates stems from the choice of the risk-projection model and the dose-response relationsip. The choice between a linear and a linear-quadratic dose-response model may alter the risk estimate by a factor of about two. The method of analysis (e.g., relative vs absolute risk model) can alter the risk estimate by an additional factor of three. Choosing different age and sex distributions can further change the estimate by another factor of up to three. The potential genetic consequences could be of significance, but at the present time, sufficient information on the age and sex distribution of the worker population is lacking for precise estimation of risk. The potential teratogenic consequences resulting from radiation are considered significant. Radiation exposure of a pregnant worker could result in developmental abnormalities.

    Clostridium species and Bacillus spp. are spore-forming bacteria that cause hospital infections. The spores from these bacteria are transmitted from patient to patient via healthcare workers' hands. Although alcohol-based hand rubbing is an important hand hygiene practice, it is ineffective against bacterial spores. Therefore, healthcare workers should wash their hands with soap when they are contaminated with spores. However, the extent of health care worker hand contamination remains unclear. The aim of this study is to determine the level of bacterial spore contamination on healthcare workers' hands. The hands of 71 healthcare workers were evaluated for bacterial spore contamination. Spores attached to subject's hands were quantitatively examined after 9 working hours. The relationship between bacterial spore contamination and hand hygiene behaviors was also analyzed. Bacterial spores were detected on the hands of 54 subjects (76.1%). The mean number of spores detected was 468.3 CFU/hand (maximum: 3300 CFU/hand). Thirty-seven (52.1%) and 36 (50.7%) subjects were contaminated with Bacillus subtilis and Bacillus cereus, respectively. Nineteen subjects (26.8%) were contaminated with both Bacillus species. Clostridium difficile was detected on only one subject's hands. There was a significant negative correlation between the hand contamination level and the frequency of handwashing (r = -0.44, P < 0.01) and a significant positive correlation between the hand contamination level and the elapsed time since last handwashing (r = 0.34, P < 0.01). Healthcare workers' hands may be frequently contaminated with bacterial spores due to insufficient handwashing during daily patient care.

    Noncommunicable diseases (NCDs) are becoming more prevalent in India. The data for presence of NCDs and its risk factors among factory workers is deficient in India. A cross-sectional comparative study was carried out among 37 factory workers and equal number of comparable subjects from general population. Screening for presence of diabetes along with its risk factors was made in both the groups using pretested predesigned World Health Organization STEPwise approach to surveillance (WHO STEPS) questionnaire in rural area of Delhi. Data was analyzed using SPSS version 16 software. The estimation of risk in two groups was done with calculation of odds ratio (OR). P values less than 0.05 were considered significant. A total of 74 participants were included in the present study. Hypertension and diabetes was present in 13.5 and 5.4% of factory workers and four (10.8%) and three (8.8%) subjects in comparative group, respectively. Seven (18.9%) factory and eight (21.6%) non-factory subjects fell in the category of current smoker or smokeless tobacco users. High density lipoprotein levels were found abnormal among one (2.7%) factory worker and nine (24.3%) subjects in comparative group (P-value = 0.01). Behavioral risk factors, alcohol consumption, and fruits and vegetable intake were significantly different among two groups. Factory workers were having better profile than non-factory subjects except for risk factors such as alcohol intake and inadequate fruits and vegetable intake. However, healthy worker effect phenomenon cannot be ruled out.

Screening for presence of diabetes along with its risk factors was made in both the groups using pretested predesigned World Health Organization STEPwise approach to surveillance (WHO STEPS) questionnaire in rural area of Delhi. Data was analyzed using SPSS version 16 software. The estimation of risk in two groups was done with calculation of odds ratio (OR). P values less than 0.05 were considered significant. Results: A total of 74 participants were included in the present study. Hypertension and diabetes was present in 13.5 and 5.4% of factory workers and four (10.8%) and three (8.8%) subjects in comparative group, respectively. Seven (18.9%) factory and eight (21.6%) non-factory subjects fell in the category of current smoker or smokeless tobacco users. High density lipoprotein levels were found abnormal among one (2.7%) factory worker and nine (24.3%) subjects in comparative group (P-value = 0.01). Behavioral risk factors, alcohol consumption, and fruits and vegetable intake were significantly different among two groups. Conclusion: Factory workers were having better profile than non-factory subjects except for risk factors such as alcohol intake and inadequate fruits and vegetable intake. However, healthy worker effect phenomenon cannot be ruled out. PMID:23776324

    We show that worker wellbeing is determined not only by the amount of compensation workers receive but also by how compensation is determined. While previous theoretical and empirical work has often been preoccupied with individual performance-related pay, we find that the receipt of a range of group-performance schemes (profit shares, group bonuses and share ownership) is associated with higher job satisfaction. This holds conditional on wage levels, so that pay methods are associated with greater job satisfaction in addition to that coming from higher wages. We use a variety of methods to control for unobserved individual and job-specific characteristics. We suggest that half of the share-capitalism effect is accounted for by employees reciprocating for the "gift"; we also show that share capitalism helps dampen the negative wellbeing effects of what we typically think of as "bad" aspects of job quality.

    Full Text Available The dispersion of latex allergen bound on glove powder has been shown to be of clinical importance to latex-sensitized medical staff and patients. To investigate whether latex aeroallergen is associated with the development of latex allergic reactions in health care workers, air samples were collected in 33 hospital rooms and two physicians' offices. Concentrations of latex allergens in the samples were determined by a competitive inhibition immunoassay and related to reported hypersensitivity reactions and to specific IgE results of 111 staff members engaged in these rooms. Latex aeroallergen (up to 205 ng/m3 could be detected in all rooms where powdered latex gloves were used and ventilation systems were not installed. Conjunctivitis (n=10, rhinitis (n=12 and dyspnea (n=4 were reported exclusively by employees working in such contaminated rooms. Also workers with latex-specific IgE antibodies (n=l 7 were found only in these rooms. Urticaria in personnel (n=26 was reported in rooms with and without detectable allergen load. All symptoms were significantly associated with latex-specific IgE antibodies. Our results demonstrate that immediate-type sensitization and allergic symptoms are associated with detectable latex aeroallergen.

    Although medication is acknowledged as a key element in treating health problems, there is little information available on the use of medication by hospital workers. To estimate the prevalence and describe the patterns of medication consumption by hospital workers and to identify the factors associated with such consumption in this population, data from the "PROSEC" baseline cohort were analyzed (n=417). The prevalence of overall medication consumption was 72.4%, most of which was for nervous complaints (25.4%), especially analgesics (17.8%). Use of any amount of medication was independently associated with gender, number of medically diagnosed conditions and health problem in the two weeks prior to the interview. Use of a drug was significantly associated with income whereas self-diagnosed health problems were independently related with the use of two or more pharmaceutical products. The high prevalence of medication usage in this population, with analgesics being the most consumed medication, should be seen as a cause for concern, since many consumers are unaware that these products are not exempt from risk. Women and individuals in poor health are the main candidates for intervention programs in order to promote adequate and proper use of these pharmaceutical products.

    Fluorescence in situ hybridization (FISH) is a powerful new technique that allows numerical chromosome aberrations (aneuploidy) to be detected in interphase cells. In previous studies, FISH has been used to demonstrate that the benzene metabolites hydroquinone and 1,2,4-benzenetriol induce aneuploidy of chromosomes 7 and 9 in cultures of human cells. In the present study, we used an interphase FISH procedure to perform cytogenetic analyses on the blood cells of 43 workers exposed to benzene (median=31 ppm, 8-hr time-weighted average) and 44 matched controls from Shanghai, China. High benzene exposure (>31 ppm, n=22) increased the hyperdiploid frequency of chromosome 9 (p<0.01), but lower exposure (<31 ppm, n=21) did not. Trisomy 9 was the major form of benzene-induced hyperdiploidy. The level of hyperdiploidy in exposed workers correlated with their urinary phenol level (r= 0.58, p < 0.0001), a measure of internal benzene close. A significant correlation was also found between hyperdiploicly and decreased absolute lymphocyte count, an indicator of benzene hematotoxicity, in the exposed group (r=-0.44, p=0.003) but not in controls (r=-0.09, P=0.58). These results show that high benzene exposure induces aneuploidy of chromosome 9 in nondiseased individuals, with trisomy being the most prevalent form. They further highlight the usefulness of interphase cytogenetics and FISH for the rapid and sensitive detection of aneuploidy in exposed human populations. 35 refs., 3 figs., 2 tabs.

    Health care support occupations have an assault-injury rate nearly 10 times the general sector. Emergency departments (EDs) are at greatest risk of such events. The objective was to describe the incidence of violence in ED health care workers (HCWs) over 9 months. Specific aims were to (1) identify demographic, occupational, and perpetrator factors related to violent events (VEs) and (2) identify predictors of acute stress in victims and predictors of loss of productivity. A longitudinal, repeated-methods design was used to collect monthly survey data from ED HCWs at 6 hospitals. Surveys assessed number and type of VEs, and feelings of safety and confidence. Victims also completed specific VE surveys. Descriptive statistics and a repeated-measure linear regression model were used. Two hundred thirteen ED HCWs completed 1795 monthly surveys and 827 VEs were reported. Average VE rate per person per 9 months was 4.15. Six hundred one events were physical threats (PTs) (3.01 per person). Two hundred twenty six events were assaults (1.13 per person). Five hundred one VE surveys were completed, describing 341 PTs and 160 assaults. Men perpetrated 63% of PTs and 52% of assaults. Significant differences in VEs were reported between registered nurses (RNs) and medical doctors (MDs) (P = .0017) and patient care assistants (P stress than the MDs (P stress reduced productivity (P stress, and lost productivity. Acute stress has negative consequences on workers' ability to perform their duties. Copyright © 2013 Elsevier Inc. All rights reserved.

    2003-07-01

    This report investigates the importance professional divers and offshore workers give to safety culture in reducing accident probability. Using a conjoint analysis method 'accident risk' scenarios were used to estimate weights for influence of safety culture, quality of workplace supervision, time pressure and worker competency. The 'expected' weighting, if all factors were equally significant was 1.0 for each factor. All four factors contributed significantly to participants' assessment of accident probability but highest weighting was given to quality of supervision (1.48). Safety culture was given significantly lower weighting by offshore divers (0.74) than offshore workers (0.97). Time/financial pressure and worker competency were given close to expected weightings. Weightings were not influenced by supervisory status, accident history or being in current offshore industry employment. Participants were also asked to define safety culture in their own words. Definitions of safety culture were associated with the role of the organisation/company, the role of management, individual safety awareness, equipment and team/group interaction. (author)

    2009-09-01

    The implementation of an innovative office concept (e.g. open-plan, flexible workplaces and a paperless office concept) on health and productivity among office workers was evaluated with questionnaires of 138 workers at baseline and 6 and 15 months afterwards. Work-related fatigue, general health, change in health status, upper extremity complaints and perceived productivity were outcomes. No short-term significant differences were found in most outcomes except for quantity of performed work (decrease from 96% to 92%, p = 0.008). In the long-term, no significant differences were found in most outcomes except for an increase in general health (p = 0.011) and a decrease in prevalences of upper extremity complaints (33% to 22%, p = 0.021). Perceived productivity increased significantly 15 months after the implementation. It is concluded that innovative office concepts had no or limited effects on work-related fatigue, health changes and productivity but some positive effects on workers' general health and upper extremity complaints in the long term. Office innovation is being administered often but up to now seldom evaluated on workers' health and productivity.

    Full Text Available In today’s global age many people cross national borders in search of better work and more wages. According to IOM, more than 100 000 000 workers leave their homeland and migrate to another country for this reason. Europe and North America have already experienced increase in foreign labor for many decades but nowadays, it is very common to see foreign laborers in Asian countries. As the number of foreign laborers rapidly increased, however, so did many social problems in relation to these workers. No country is safe from or immune to such social problems in regards to the foreign workers especially with a much easier and more efficient transportation system. In case of South Korea, the history of foreign labor may not be as long as other nations but as of 2007, it boasts of more than 250 000 foreign laborers and is thus facing just as many social problems as well. In order to investigate such social issues, this article explores the history of foreign laborers and their current situation in South Korea. Furthermore, this artticle examines both internal and external factors which may have caused exponential growth of foreign labor market in South Korea in the past decade.

    Full Text Available Global literature has suggested a negative impact of acculturative stress on both physical and mental health among international migrants. In China, approximately 20 percent of its population is rural-to-urban migrant workers and there are significant cultural differences between rural and urban societies, but no data are available regarding the acculturative stress of Chinese migrant workers. This study aimed to explore the forms and contexts of acculturative stress among Chinese migrant workers.Qualitative data were collected from four focus group discussions with 17 Chinese rural-to-urban migrant workers and three individual interviews with three medical professionals who provided mental health services for factory-workers in Shenzhen, China.The data in the current study showed that rural-to-urban migrant workers in China had experienced various forms of acculturative stress including difficulties in adapting to the environment, work-related stress, family-related stress, financial hardship, and lack of sense of belonging to cities.Rural-to-urban migration in China is a challenging transition with significant acculturative stress and demands for major adjustments among migrant workers. The assessment and management of acculturative stress is a necessary first step in providing mental health services to migrant workers.

To compare the effect of cotton and jute dust, respiratory symptoms were studied and respiratory function measured in 60 cotton and 91 jute non-smoking female workers of similar age distribution, similar length of exposure to dust, and exposed to similar respirable airborne dust concentrations. Cotton workers had a significantly higher prevalence of byssinosis, of persistent cough, and of dyspnoea (P jute workers. Among cotton workers 28·3% were found to have characteristic symptoms of byssinosis, whereas none was found among jute workers. Exposure to cotton but also to jute dust caused significant reductions of FEV1·0, FVC, and PEF (P jute and cotton dust effects has shown that about 30% of cotton workers had functional grades F1 and F2, while only 13% of jute workers were found in the same grades (F1). It is concluded that cotton dust may be considered more active than jute though the latter cannot be considered inactive. PMID:5124836

    Full Text Available Job stress is a great problem in developed countries of the world, but in Yugoslavia, it is increased due to additional reasons associated with economic crisis in the society. Health services and health workers are in particulary difficult conditions. The aim of this paper was to examine sources and causes of job stress in health workers. Material and methods The research was undertaken among health workers treated at Health Centre "Hospital" in Novi Sad. The study group included health workers - doctors nurses and laboratory workers, and the control group included the rest of non-medical staff. Adapted Siegrist questionnaire was used. Three factors were examined: extrinsic efforts (disturbances at work, sense of great job responsibility and the need for overtime work; intrinsic efforts (major criticism, thinking about the job from the early morning, getting nervous because of minor problems, discontentment because of unsolved problems at work, relaxation at home and so on, and low reward (respect from the superiors and colleagues, support and security at workplace. Answers were scored indicating intensity (high, moderate, low, not at alt. Statistic analysis included testing the level of significance in health workers in relation to non-medical staff (t test and Fisher's exact test. Results Applying the scoring system it has been established that health workers are exposed to greater job stress, great sense of very high job responsibility and frequent overtime work (p<0,001 than the control group. In regard to answers from the second group - intrinsic effort and low reward, there was no statistical significance between the study and control group. Generally high level of risk factors was established, especially presence of one or more risk factors. Discussion Job stress increases absenteeism, reduces work productivity, causes higher expenses of medical treatment, rehabilitation and staff retraining. It is of great importance to identify factors

    A group of 50 workers exposed to coal tar pitch volatiles (CTPV) in an aluminum reduction plant and a group of 50 non-exposed workers were selected to evaluate the genotoxic effects of CTPV exposure. A battery of tests was performed on 3 different body fluids; urine, blood and semen. Urine samples were evaluated for mutagenic constituents using the Ames/Salmonella assay. Cultured lymphocytes from blood samples were used to perform cytogenetic analysis. Semen samples were used to measure sperm count, percent abnormal sperm morphology and frequency of sperm carrying double fluorescent bodies (2-F). 14 of 28 (50%) exposed workers and 7 of 36 (19.4%) non-exposed workers had mutagenic urine. This difference was significant (p less than 0.01). Among the non-smokers a significantly higher percentage of workers who were exposed had positive urine (36%) compared to the non-exposed workers (5%) (p less than 0.05). Among the exposed group, more mechanics had mutagenic urine than did other types of workers. Overall chromosome aberration rates were similar in both exposed and non-exposed workers. Among exposed workers a significant inverse correlation (p less than 0.05) between age and chromatid aberration rate was observed. Results of semen analysis failed to detect differences between exposed and non-exposed workers. Results of these tests lend support to a battery approach to genetic monitoring and suggest a link between exposure to CTPV and genotoxic effects. Detection of exposure to mutagens at an early time offers an opportunity for disease prevention by the reduction of exposure.

    1987-05-01

    The individual roles of honeybee workers and drones in heat regulation were investigated using single combs of bees and brood (about 1,000 individuals) placed in boxes at 15 degrees C. After 1 h and before cluster formation, I measured the elevation of bee thoracic surface temperature (Tths) above local ambient temperature (Ta). Bees were then left overnight at 15 degrees C. During the preclustering period, the density of bees over the brood slowly increased. In the clusters left overnight, bees in the innermost layer were significantly younger than bees in the outermost layer. One-day-old bees and drones were always located in the innermost cluster layer. 89% of all workers measured had Tths - Ta greater than or equal to 2 degrees C, indicating that most workers contribute to colonial thermogenesis. Average Tths - Ta was 4.1 degrees C. Drones measured had the same average Tths - Ta as unmarked workers. Tths - Ta did not differ among bees 2 days of age and older. Location on or off the brood did not affect Tths - Ta. Cooling constants of dead bees placed near the comb in the box averaged 1.036 min-1 and were independent of location on the comb. Calculated average thoracic conductance was 0.829 cal g-1 degree C-1 min-1. Average calculated heat production per worker was 0.095 cal min-1, less than 15% of the maximal oxygen consumption of 4-day-old bees. Calculations indicate that the larger drones contribute more heat per bee than do the workers.(ABSTRACT TRUNCATED AT 250 WORDS)

    While several studies of smoking behaviors in rural-to-urban Chinese migrants exist, none to our knowledge have focused on factory workers, estimated to represent between 10% and 20% of China's total rural-to-urban migratory population. This paper assesses factors associated with smoking behavior among rural-to-urban migrant factory workers in Shenzhen, China. A cross-sectional survey of migrant workers from 44 randomly selected factories in Shenzhen, China. Participants were migrant factory workers aged 16-59 years and holding nonlocal household registration. The main outcome measures were demographic, migration-related, and behavioral factors associated with smoking status. Four thousand and eighty-eight completed questionnaires were obtained (response rate 95.5%). Overall smoking prevalence (including occasional, daily, and heavy daily smoking) was 19.1%. The prevalence of daily smoking (including heavy daily smoking) was higher in men (27.3%) than women (0.7%). These rates are significantly lower than national smoking rates (59.5% in men, 3.7% in women) and rates found in a similar study. A high-risk group of men who smoke heavily and consume alcohol frequently was identified. Longer working hours and less rest were associated with higher rates of smoking. Frequent Internet use and lack of insurance were associated with lifetime smoking. Gender-adjusted models showed that poorer mental health and an accumulated working time in Shenzhen of 2-3 years increased female workers' likelihood of smoking. Migrant factory workers in Shenzhen had lower rates of smoking than other population groups in China. The identification of risk factors for heavy smoking may help to effectively target health promotion interventions.

    Construction workers are known to have occupational dermatoses. The prevalence of such dermatoses was unknown in Taiwanese construction workers. The objective of this study was to determine the work exposure, prevalence of skin manifestations, and sensitivity to common contact allergens in cement workers of southern Taiwan. A total of 1147 current regular cement workers were telephone-interviewed about skin problems during the past 12 months, work exposure, and personal protection. Among those interviewed, 166 were examined and patch tested with common contact allergens. A high % of cement workers reported skin problems in the past 12 months. More men (13.9%) reported skin problems possibly related to work than women (5.4%). Prevalence was associated with lower use of gloves, duration of work as cement worker, and more time in jobs involving direct manual handling of cement, especially tiling. A high % of dermatitis was noted in the 166 workers examined, which correlated with reported skin problems. On patch testing, construction workers had a high frequency of sensitivity to chromate. Sensitivity to chromate or cobalt was associated with reported skin problems, or dorsal hand dermatitis on examination. These workers' dermatitis was under-diagnosed and inadequately managed. It is concluded that cement workers in southern Taiwan had a high prevalence of skin problems related to cement use. Protective measures, work practice, and physician education should be improved to prevent or manage such problems.

    Objectives. This study examined absence rates among US Department of Energy workers who had beryllium sensitization (BeS) or were diagnosed with chronic beryllium disease (CBD) compared with those of other workers. Methods. We used the lymphocyte proliferation test to determine beryllium sensitivity. In addition, we applied multivariable logistic regression to compare absences from 2002 to 2011 between workers with BeS or CBD to those without, and survival analysis to compare time to first absence by beryllium sensitization status. Finally, we examined beryllium status by occupational group. Results. Fewer than 3% of the 19 305 workers were BeS, and workers with BeS or CBD had more total absences (odds ratio [OR] = 1.31; 95% confidence interval [CI] = 1.18, 1.46) and respiratory absences (OR = 1.51; 95% CI = 1.24, 1.84) than did other workers. Time to first absence for all causes and for respiratory conditions occurred earlier for workers with BeS or CBD than for other workers. Line operators and crafts personnel were at increased risk for BeS or CBD. Conclusions. Although not considered “diseased,” workers with BeS have higher absenteeism compared with nonsensitized workers. PMID:25211750

    Full Text Available Noise induced hearing loss (NIHL is an irreversible sensorineural hearing loss associated with exposure to high levels of excessive noise. Prevention measures are not well established in developing countries. This comparative cross sectional study aims to determine the prevalence of hearing loss in both a group of high risk workers and a control group and to assess their knowledge of the effects of noise on hearing health. A total of 101 market mill workers and 103 controls employed within markets in the city of Accra, Ghana, were evaluated using a structured questionnaire and pure tone audiometry. The questionnaire assessed factors including self-reported hearing loss, tinnitus, knowledge on the effects of noise on hearing health and the use of hearing protective devices. Pure tone audiometric testing was conducted for both mill workers and controls. Noise levels at the work premises of the mill workers and controls were measured. Symptoms of hearing loss were reported by 24 (23.76% and 8 (7.7% mill workers and controls respectively. Fifty-five (54.5% and fifty-four (52.37% mill workers and controls exhibited knowledge of the effects of noise on hearing health. Five (5.0% mill workers used hearing protective devices.

    Emerging research has shown that co-workers have a significant influence on the return-to-work outcomes of partially fit ill or injured employees. By drawing on theoretical findings from the human resource and wider behavioral sciences literatures, our goal was to formulate a theoretical model of the influences on and outcomes of co-worker responses within work reintegration. From a search of 15 data bases covering the social sciences, business and medicine, we identified articles containing models of the factors that influence co-workers' responses to disability accommodations; and, the nature and impact of co-workers' behaviors on employee outcomes. To meet our goal, we combined identified models to form a comprehensive model of the relevant factors and relationships. Internal consistency and externally validity were assessed. The combined model illustrates four key findings: (1) co-workers' behaviors towards an accommodated employee are influenced by attributes of that employee, the illness or injury, the co-worker themselves, and the work environment; (2) the influences-behaviour relationship is mediated by perceptions of the fairness of the accommodation; (3) co-workers' behaviors affect all work reintegration outcomes; and (4) co-workers' behaviours can vary from support to antagonism and are moderated by type of support required, the social intensity of the job, and the level of antagonism. Theoretical models from the wider literature are useful for understanding the impact of co-workers on the work reintegration process. To achieve optimal outcomes, co-workers need to perceive the arrangements as fair. Perceptions of fairness might be supported by co-workers' collaborative engagement in the planning, monitoring and review of work reintegration activities.

    Elaborate division of labour has contributed significantly to the ecological success of social insects. Division of labour is achieved either by behavioural task specialization or by morphological specialization of colony members. In physical caste systems, the diet and rearing environment of developing larvae is known to determine the phenotype of adult individuals, but recent studies have shown that genetic components also contribute to the determination of worker caste. One of the most extreme cases of worker caste differentiation occurs in the army ant genus Eciton, where queens mate with many males and colonies are therefore composed of numerous full-sister subfamilies. This high intracolonial genetic diversity, in combination with the extreme caste polymorphism, provides an excellent test system for studying the extent to which caste determination is genetically controlled. Here we show that genetic effects contribute significantly to worker caste fate in Eciton burchellii. We conclude that the combination of polyandry and genetic variation for caste determination may have facilitated the evolution of worker caste diversity in some lineages of social insects.

    Leaf-cutting ants belonging to the tribe Attini are major herbivores and important agriculture pests in the neotropics, these ants being thought to feed on the sap which exudes from the plant material which they cut and also on the mycelium of a symbiotic fungus that grows on plant material inside their nests in what is called "the fungus garden". However, we have found that the survival of Atta sexdens worker ants on leaves, on mycelium of the ants' symbiotic fungus, Leucoagaricus gongylophorus, or on plant polysaccharides was the same as that of starved A. sexdens, while, conversely, significantly longer survival was achieved by ants fed on the fungus garden material or on some of the products (especially glucose) of the hydrolysis of plant polysaccharides. We found that the fungus garden contained glucose at a higher concentration than that found in leaves or fungal mycelium, and that this glucose was consumed by the ant to the extent that it was probably responsible for up to 50% of the nutritional needs of the workers. The fungus garden contained polysaccharide degrading enzymes (pectinase, amylase, xylanase and cellulase) in proportions similar to that observed in laboratory cultures of L. gongylophorus. It thus appears that A. sexdens workers obtain a significant part of their nutrients from plant polysaccharide hydrolysis products produced by the action of extracellular enzymes released by L. gongylophorus. In this paper we discuss the symbiotic nutrition strategy of A. sexdens workers and brood and the role played by plant polysaccharides in the nutrition of attine ants.

    Physical and mental health of workers is threatened due to various events and chronic occupational stress. This study was conducted to investigate the relationship between occupational stress and gastric disease in male workers of the shipbuilding industry. Occupational stress measured among a total of 498 workers of a shipbuilding firm who visited the hospital for health examination using the Korean Occupational Stress Scale (KOSS)-short form, and the relationship between sociodemographic factors, health-related behaviors, occupational stress, and gastric disease, and the distribution of occupational stress by sociodemographic factors in the gastric disease group was examined. There was no significant association between gastric disease and total occupational stress score and its seven sub-factors. The analysis showed that risk of gastric disease was significantly higher in the Q1 group in which the stress caused by occupational discomfort among seven sub-factors was lowest than that in the Q4 group (odds ratio, 2.819; 95% confidence interval, 1.151 to 6.908). Analysis only on the gastric disease group showed that the stress score of laborers was higher in the four sub-factors than that of office workers (P stress in the low-educated and laborers. It is recommended for future studies to confirm the causal relationship between occupational stress and gastric disease by large scale studies using a KOSS which appropriately reflects workplace culture.

    Tobacco use has a substantial impact on hospitality industry employees because of the disproportionate prevalence of smoking among these workers and because of the high levels of secondhand smoke to which they are exposed. The severity of this impact is evidenced by the high mortality rates observed among hospitality industry workers from diseases related to tobacco smoke exposure. Several states and localities have begun to enact laws to protect these workers from secondhand smoke exposure. Such policies seem to be effective in reducing exposure and improving health among these workers without causing any adverse impact on business. Occupational clinicians can play a significant role in protecting the health of hospitality workers by supporting laws to create smoke-free workplaces, including bars and restaurants, and promoting smoking cessation in these worksites.

    Forest work, an occupation with some of the highest injury and illness rates, is conducted primarily by Latino immigrant workers. This study evaluates a pilot program where promotoras (lay community health educators) provided occupational health and safety trainings for Latino forest workers. Evaluation methods included a focus group, post-tests, and qualitative feedback. Community capacity to address working conditions increased through (i) increased leadership and community access to information and resources; and (ii) increased worker awareness of workplace health and safety rights and resources. Fear of retaliation remains a barrier to workers taking action; nevertheless, the promotoras supported several workers in addressing-specific workplace issues. For working conditions to significantly improve, major structural influences need to be addressed. A long-term, organizationally supported promotora program can play a key role in linking and supporting change at the individual, interpersonal and community levels, contributing to and supporting structural change. © 2014 Wiley Periodicals, Inc.

    The observation of orthostatic hypotension in an index case of manganese toxicity lead to this prospective attempt to evaluate cardiovascular autonomic function and cognitive and emotional neurotoxicity in eight manganese alloy welders and machinists. The subjects consisted of a convenience sample consisting of an index case of manganese dementia, his four co-workers in a "frog shop" for gouging, welding, and grinding repair of high manganese railway track and a convenience sample of three mild steel welders with lesser manganese exposure also referred because of cognitive or autonomic symptoms. Frog shop air manganese samples 9.6-10 years before and 1.2-3.4 years after the diagnosis of the index case exceeded 1.0 mg/m3 in 29% and 0.2 mg/m3 in 62%. Twenty-four-hour electrocardiographic (Holter) monitoring was used to determine the temporal variability of the heartrate (RR' interval) and the rates of change at low frequency (0.04-0.15 Hz) and high frequency (0.15-0.40 Hz). MMPI and MCMI personality assessment and short-term memory, figure copy, controlled oral word association, and symbol digit tests were used. The five frog shop workers had abnormal sympathovagal balance with decreased high frequency variability (increased ln LF/ln HF). Seven of the eight workers had symptoms of autonomic dysfunction and significantly decreased heart rate variability (rMSSD) but these did not distinguish the relative exposure. Mood or affect was disturbed in all with associated changes in short-term memory and attention in four of the subjects. There were no significant correlations with serum or urine manganese. Power spectrum analysis of 24-h ambulatory ECG indicating a decrease in parasympathetic high frequency activation of heart rate variability may provide a sensitive index of central autonomic dysfunction reflecting increased exposure to manganese, although the contribution of exposures to solvents and other metals cannot be excluded.

    Full Text Available This cross-sectional analytic study aimed to investigate ergonomic hazards in the workplace for musculoskeletal pain among university office workers. There were 142 full-time office staff from Khon Kaen University. Demographic characteristics and musculoskeletal pain were evaluated from a structured questionnaire. Ergonomic workstations, i.e. size of table, seat, work area and illuminations were measured at the workstations and anthropometric parameters were determined. Descriptive statistics were used for data analysis which were percentage, mean, and standard deviation. Inferential statistics were chi-square test and the student t-test at 95 % confidence interval. The results showed that 81.7 % of office workers were female, the mean age was 38.0 ± 10.0 years, the average work experience was 12.3 ± 10.8 years. One-month prevalence of musculoskeletal pain was 69.0 %. The onset of symptoms was during working hours and the majorly reported the cause as prolonged sitting in the same posture at work (73.3 %. From measurements, 55.8 % of all workstations had insufficient illumination being lower than the minimum standard requirement (400 lux. Most workstations (75.6 % had significantly inappropriate height (above elbow height of workers at p < 0.001. From questionnaires, the seat height was significantly associated with musculoskeletal pain (p = 0.034. Moreover, anthropometric characteristics of musculoskeletal pain cases (i.e. buttock-popliteal length, hip breadth, sitting elbow height were significantly different from healthy office workers (p < 0.05. The findings suggest that ergonomic workstations need to be improved appropriately for individual workers and improvements in working conditions following standard requirements should be considered.

    Consistent and correct use of condoms is important to prevent the transmission of HIV and other sexually transmitted diseases. We evaluated condom use skills on an 11-point scale in which participants were observed placing a condom on a penile model. Participants were 375 sexually active African American and Hispanic migrant workers. For analysis, subjects were divided into skilled and unskilled groups by a median split of the condom use skills score. Sexual risk behaviors were analyzed between condom use skilled and unskilled groups and level of condom use skills between African Americans and Hispanics. African Americans showed better skills in using condoms, and participants in the condom-use skilled group used condoms more frequently. Finally, a logistic regression was conducted to find predictors of condom use skills. Significant predictors were ethnicity, language, and assistance-related social support (obtaining advice from people who could provide tangible assistance).

  12. Wage determination and discrimination among older workers.

    In this study, the determinants of the wage rates of a large sample of individuals aged 58 to 63 are first analyzed. Second, an explanation for the large discrepancies existing between the average wage rates earned by whites and nonwhites and by men and women is attempted. Human capital and geographic variables were found to be important wage determinants. Education, vocational training, years of job tenure, health, region of residence and local cost of living were significant explanators, especially for whites. Differences in these variables, however, cannot completely explain the wage differentials that exist by race and sex. There is a large unexplained component (especially in the male-female comparison) offering evidence of race and sex discrimination among older workers. In the case of sex discrimination, much of the problem appears to be occupational segregation--the crowding of women into low paying industries and occupations.

    In this work, we analyze various consequences of the phenomenon of mobbing on the health of a work sector with special characteristics: the agro fruit sector. For this purpose, we collected data from a sample of 396 workers (61 men and 331 women) belonging to this sector in the Region of Murcia (Spain). A questionnaire with the following measurement instruments was administered: a Spanish adaptation of the revised Negative Acts Questionnaire (Sáez, García, & Llor, 2003), the Psychosomatic Problems Questionnaire (Hock, 1988), and a measure of absenteeism. The results revealed a significant and positive relation between workplace mobbing and psychosomatic symptoms, but not with absenteeism. The implications of the results for future research are discussed.

    The General Health Questionnaire (GHQ12) and physical fitness tests were administered to 338 workers in clean rooms producing electronic parts in 12-h shifts. The results were compared to those in 95 workers in 8-h shifts and 284 daytime management, clerical and engineering workers. The 12-h shift workers complained of poor health, dissatisfaction with life and poor recuperation from fatigue more than the 8-h shift workers although the rates of complaints were highest in the daytime workers. The GHQ scores were similar in the two shift groups, and much better than those in the daytime workers. However, the 12-h shift workers showed significantly lower fitness levels than the 8-h shift workers, and the levels were even worse than the daytime workers who had higher mean age and BMI levels compared with the shift workers. The tendency to have sedentary freetime activities and larger alcohol and cigarette consumption were observed in the 12-h shift workers. The 12-h shift work may have contributed to the unhealthy behaviors resulting in lower physical fitness levels. Health promotion services at the workplace should devote greater attention to long-hour shift workers, together with devising the ways to improve working conditions and environments for reducing fatigue at work.

    Full Text Available BACKGROUND Rice mill industry is the oldest and largest agro based industry. Load handling, i.e. lifting and carrying heavy load of grain filled sacs is the major job component. One of the most common work-related injuries is the development of musculoskeletal disorders caused by heavy lifting and performing the task that required repetitive motions. This made us to study the prevalence of musculoskeletal disorder among the rice mill workers. AIMS AND OBJECTIVES To study socio-demographic profile of rice mill workers. To study the prevalence of musculoskeletal disorder among the rice mill workers. To study the association of duration of work in rice mill and musculoskeletal disorders in rice mill workers. MATERIAL AND METHODS Study Design: Cross-sectional study. Study Setting: Rice mills of Karimnagar Mandal. Study Period: 12 months. Study Population: All the permanent workers working were included. RESULTS AND DISCUSSION Among the total study subjects 34% were illiterate, 66% were belonging to class IV and V socio-economic status. Majority (50.7% of the male workers have an occupational history more than 10 years. Similarly, majority (38.9% of the female workers have an occupation history of 10 yrs. followed by 25.6% in 5-10 yrs. and 16.8% in < 5 yrs.

    The cause or causes of asthma among employees in aluminum smelters is unknown. We attempted to ascertain whether such workers who developed asthma differed in respect to indices of immunological function and certain genetic markers. Data were collected from 33 asthmatic and 127 nonasthmatic potroom workers. Asthmatic workers had significantly lower mean serum levels of immunoglobulin (Ig)M; however, mean levels of IgG and IgA, median levels of IgE, the capacity for recall of delayed type hypersensitivity, levels of immune complexes, and frequency of antinuclear or other autoantibodies did not differ from values for nonasthmatic workers. Asthma was found to develop on a background of atopy in 21 workers (64%), whereas there were no features of atopy in 12 workers (36%). Cigarette smoking had independent effects on immunological function. In respect to genetic markers, there was a higher frequency among asthmatic workers of the alpha-1-anti-trypsin deficiency phenotype MS, but the frequency of blood groups, Gm allotypes, or human leucocyte antigen types was similar. The study established that the profile of immune function, or genetic markers tested, did not differ essentially for workers in an aluminum smelter who did or did not develop asthma; however, there was an indication of heterogeneity in causation, as judged by atopy-related and non-atopy-related groups in the asthma population.

    AIM: TO examine the associations between objective health indicators and high need for recovery (NFR) after work, one of the subjective presentations of work related-fatigue, among apparently healthy workers in modern workplaces. METHODS: From October to December, 2007, an annual health examination was performed for the workers from an electronics manufacturing factory in Taiwan. Health records of 1216 workers with a relatively homogeneous socioeconomic status were used for analysis. The health checkups included personal and NFR scale questionnaires, physical examinations, blood tests for biochemistry and hematology. The workers within the top tertile NFR score were defined as high-NFR workers. RESULTS: After adjusted for potential confounders, the workers with elevated alanine aminotransferase (ALT) and central obesity had a significantly higher NFR after work, with increased risks of 1.4-fold [95% confidence interval (CI) = 1.01-2.0] and 1.8-fold (95% CI = 1.2-2.7), respectively. Shiftworkers had a 2.0-fold (95% CI = 1.5-2.6) increased risk for high-NFR. The associations between high-NFR and lipid profiles, blood sugar, hematology indexes or blood pressure were insignificant after controlling for confounders. CONCLUSION: For apparently healthy workers, high NFR after work is not simply a subjective experience. Objective health measures, such as elevated ALT and increased waist circumference, should be carefully evaluated for the apparently healthy workers having a higher NFR after work.

    The objectives of the present study were to study the (i) prevalence of hypertension and hearing impairment in iron and steel industry workers, (ii) association between hypertension and hearing impairment, (iii) association between hypertension and hearing impairment, with duration of exposure, and (iv) correlation between levels of sound and noise induced health problems viz. hypertension and hearing impairment in a cross sectional study involving Workers working in iron and steel industry at Nagpur. Of a total of 804 workers, 770 workers participated in the study. There were five sections in the factory; Steel melting section (SMS), rolling mill section (RMS), quality control department (QCD), maintenance department (MD) and administration department (AD). Workers working in SMS, RMS, & QCD formed a continuously exposed group (CEG); workers of MD and AD formed intermittently exposed group (IEG). Workers were interviewed, examined and information was collected in a pre-tested pro-forma. Blood pressure was measured, and tuning fork tests were done to assess hearing ability. Prevalence of hypertension among CEG (25.51%) was significantly higher than IEG (14.05%). (X2-14.28, df-1, P0.05). The results of the present study indicate that hypertension and hearing impairment are commoner in workers continuously exposed to high levels of occupational noise.

    Styrene is a basic building block for manufacturing thousands of products throughout the world. The present study aimed to (1) detect the presence of styrene and/or its metabolites in the workers in one of the Egyptian plastic factories; (2) demonstrate some common health effects of styrene exposure among the same group by some laboratory investigations and compare them with the unexposed healthy individuals; and (3) correlate the duration of styrene exposure and its level in the blood with the severity of the demonstrated health effects. This study was conducted in one of Egyptian plastic factories. The exposed group was 40 male workers, ranging in age from 18 to 33 years (23.20 ± 4.09), working 12 h/day with 1 day off, and working without any protective equipment. A control group of 50 unexposed healthy males matched with the exposed group for age (21-35 yrs (23.40 ± 4.05)), sex, socioeconomic status, and smoking habit is selected. Written individual consent is obtained from all participants followed by (a) a full medical and occupational history and full clinical examination; (b) ventilatory function tests: forced vital capacity (FVC), slow vital capacity, forced expiratory volume in the 1st second (FEV₁)%, FEV₁/FVC%, peak expiratory flow, and mid-expiratory flow 25-75%; (c) analyses of β₂ microglobulin; blood styrene level; and urinary mandelic acid; and (d) cytogenetic study. The study results showed a statistically significant difference between the exposed and the control groups as regard the blood styrene level, urinary mandelic acid level, β₂ microgloblin in urine, and chromosomal study. The study also showed a statistically significant correlation between the duration of styrene exposure and ventilatory function parameters, also between the duration of styrene exposure and some detectable chromosomal aberrations. Our study recommends the implementation of preemployment and periodic medical examinations and health education programs using

    This study was carried out in a video tape manufacturing factory in Singapore where workers were exposed to mixed solvents consisting of methyl ethyl ketone (MEK), cyclohexanone (CHE), tetrahydrofuran (THF), and toluene (TOL). The objectives were to quantify workers' exposure to the various solvents and to evaluate if there were any neurobehavioural changes among the workers compared to controls. Nineteen exposed workers out of the workforce of forty-five were studied. Twenty-six workers (with no exposure) matched for ethnic group, age, and years of education served as controls. Eight-hour personal environmental samples were analyzed for the 19 workers along with symptom questionnaires, clinical examinations, and neurobehavioural tests including the Santa Ana Dexterity, Finger Tapping, Digit Span, and Visual Reproduction tests. The mean TWA concentrations for MEK, THF, CHE, and TOL were all below the current American Conference of Governmental Industrial Hygienists Threshold Limit Values (TLV). However, the total solvents concentration index exceed unity in one of the work areas. Significant differences were observed for prevalence of headache, and eyes and nose irritation among the exposed workers. There were also significant differences for the Santa Ana test for both-hands, Digit Span test and Visual Reproduction test. However, no dose-effect relation between behavioral scores and airborne solvent exposure was noted. The study suggests that solvent-exposed workers in video tape manufacturing plants may have poorer visual motor control and recent memory impairment (visual and verbal) than unexposed workers. Dermal absorption of solvents may have played a role in these results by increasing workers exposure.

    Carpet factory produces various types of dusts and workers occupationally get exposed to them continuously. It has adverse health effects and most notably to the pulmonary functions. Nepal is one of the carpet exporter developing countries and still does have many factories within Kathmandu valley. However, the health hazards especially the status of pulmonary function of carpet factory workers from Nepal has not been studied. A cross-sectional comparative study was designed to recruit carpet factory workers and healthy controls to assess their pulmonary functions. A total of 118 subjects (59 males and 59 females) were recruited (60 carpet factory workers and 58 controls). Pulmonary function tests were carried out using Medical International Research Spirolab II portable spirometer. The carpet factory workers had significantly less FEV1 (90.37 ±16.6 % vs. 103.89±9.79%, pfactory workers had significantly higher FEV1/FVC ratio (89.96 ± 6.42 % vs. 87.12 ± 4.58 %, p = 0.007) as compared to control. Carpet industry dusts exposure adversely affects pulmonary functions among its workers. The findings significant increase in the FEV1/FVC ratio and decrease in FEV1, FVC, and PEFR suggest that the effects are both restrictive and obstructive patterns of lung disease.

    As a result of the recent implementation of work-oriented antipoverty programs, more welfare recipients can be expected to be working in low-wage jobs. With these jobs there is little hope that these workers' incomes will rise above the poverty level. One way to help support these low-wage workers is through tax reform. Although low-wage workers pay little or no federal tax, they still pay high payroll and local taxes. To help such workers keep more of their earnings, refundable taxes like earned income tax credit and child refund taxes should be expanded, and sales taxes on food should be eliminated.

    Tsunamis have inflicted death and destruction on the coastlines of the world throughout history. The occurrence of tsunamis and the resulting effects have been collected and studied as far back as the second millennium B.C. The knowledge gained from cataloging and examining these events has led to significant changes in our understanding of tsunamis, tsunami sources, and methods to mitigate the effects of tsunamis. The most significant, not surprisingly, are often the most devastating, such as the 2011 Tohoku, Japan earthquake and tsunami. The goal of this poster is to give a brief overview of the occurrence of tsunamis and then focus specifically on several significant tsunamis. There are various criteria to determine the most significant tsunamis: the number of deaths, amount of damage, maximum runup height, had a major impact on tsunami science or policy, etc. As a result, descriptions will include some of the most costly (2011 Tohoku, Japan), the most deadly (2004 Sumatra, 1883 Krakatau), and the highest runup ever observed (1958 Lituya Bay, Alaska). The discovery of the Cascadia subduction zone as the source of the 1700 Japanese "Orphan" tsunami and a future tsunami threat to the U.S. northwest coast, contributed to the decision to form the U.S. National Tsunami Hazard Mitigation Program. The great Lisbon earthquake of 1755 marked the beginning of the modern era of seismology. Knowledge gained from the 1964 Alaska earthquake and tsunami helped confirm the theory of plate tectonics. The 1946 Alaska, 1952 Kuril Islands, 1960 Chile, 1964 Alaska, and the 2004 Banda Aceh, tsunamis all resulted in warning centers or systems being established.The data descriptions on this poster were extracted from NOAA's National Geophysical Data Center (NGDC) global historical tsunami database. Additional information about these tsunamis, as well as water level data can be found by accessing the NGDC website www.ngdc.noaa.gov/hazard/

    We aimed to evaluate the relationship between swimming pool pollutants and allergic rhinitis in swimming pool workers. Twenty-seven indoor pool workers (group 1) and 49 control subjects (group 2) were enrolled in the study. A skin prick test was performed and a nasal smear was obtained from each subject to evaluate rhinitis. When the groups were compared in terms of epithelial cells, group 1 had significantly more epithelial cells than group 2. When the groups were compared with regard to eosinophils, group 1 had significantly more eosinophils than group 2. The skin prick test results for both groups were not significantly different. Indoor pool workers showed severe symptoms of rhinitis and eosinophilic nasal cytology, likely due to chlorine. Nasal cytology is an easy-to-administer diagnostic test and can be used to follow up rhinitis in indoor pool workers, along with nasal endoscopy, a detailed clinical history and a skin prick test.

    The effect of schistosomiasis on quality of life (QOL) and productivity of workers was examined. In a textile factory in Alexandria, Egypt, personal, occupational and sociodemographic data were collected from 172 workers with schistosomiasis and 172 workers without schistosomiasis. Several indicators of productivity and the World Health Organization QOL brief were used to determine the impact of schistosomiasis. The disease affected the general, physical and independence, psychological and spiritual, and social domains of QOL. Although the productivity score of workers with schistosomiasis did not differ significantly from the control group, they had significantly lower additional hours of work and lower total incentives/month. A significant relationship was found between severity of schistosomiasis and QOL domains and productivity indicators.

    Thetkathuek, Anamai; Daniell, William

    2016-01-01

    There has been a dramatic increase in the global movement of workers during the last few decades. As Thailand has developed rapidly over the past 20 years, it has attracted laborers (both authorized and unauthorized) from the neighboring countries of Myanmar, People's Democratic Republic of Lao (Lao PDR), and Cambodia. Given that agriculture has been Thailand's most important industry, its continued growth has been dependent on migrant workers. Both crop agriculture and animal-production agriculture have employed migrant labor. Migrants have been hired to plant, weed, fertilize, spray pesticides, and harvest crops such as rice, corn, sugar cane, and cassava. They have worked at rubber and coffee plantations, as well as in the production of ornamental crops. Also, migrants have labored on pig, beef, and duck farms. There have been numerous documented health problems among migrant workers, including acute diarrhea, malaria, and fever of unknown causes. Occupational illness and injury have been a significant concern, and there has been limited health and safety training. This article reviewed the demographic changes in Thailand, studied the agricultural crops and animal production that are dependent on migrant labor, discussed the health status and safety challenges pertaining to migrant workers in agriculture, and described several recommendations. Among the recommendations, the conclusions of this study have suggested that addressing the cost for health care and solutions to health care access for migrant labor are needed.

    2007-01-01

    Migrant workers, meaning those who used to be farmers but have left rural areas and found jobs in cities as a result of economic reform and rapid development in China, have made a significant contribution to the burgeoning labor market and played an important role in speeding up the transition from a planned to a market economy. This present paper considers the economic status and social attitudes of migrant workers. It is based on the analysis of a large-scale survey in 2006, which was conducted using questionnaires and covered 28 provinces, municipalities and autonomous regions throughout the country. It was found that the income status of migrant workers depends heavily on the education and technical skills that they have developed, rather than on identity-based discrimination. Surprisingly,it was also found that those on less income and of lower economic and social status show more positive attitudes to society than those who are affluent and considered of higher social status. It is concluded that the decisive factor in attitude and behavior of migrant workers is historic rather than economic.

  1. Optimization of Routine Monitoring of Workers Exposed to Plutonium Aerosols.

    In case of incidental confinement failure, mixed oxide (MOX) fuel preparation may expose workers to plutonium aerosols. Due to its potential toxicity, occupational exposure to plutonium compounds should be kept as low as reasonably achievable. To ensure the absence of significant intake of radionuclides, workers at risk of internal contamination are monitored by periodic bioassay planned in a routine monitoring programme. From bioassay results, internal dose may be estimated. However, accurate dose calculation relies on known exposure conditions, which are rarely available when the exposure is demonstrated by routine monitoring only. Therefore, internal dose calculation is subject to uncertainty from unknown exposure conditions and from activity measurement variability. The present study calculates the minimum detectable dose (MDD) for a routine monitoring programme by considering all plausible conditions of exposure and measurement uncertainty. The MDD evaluates the monitoring quality and can be used for optimization. Here, MDDs were calculated for the monitoring of workers preparing MOX fuel. Uncertain parameters were modelled by probability distributions defined according to information provided by experts of routine monitoring, of workplace radiological protection and of bioassay analysis. Results show that the current monitoring is well adapted to potential exposure. A sensitivity study of MDD highlights high dependence on exposure condition modelling. Integrating all expert knowledge is therefore crucial to obtain reliable MDD estimates, stressing the value of a holistic approach to worker monitoring.

    Roadway incidents involving motorized vehicles accounted for 24% of fatal occupational injuries in the United States during 2013 and were the leading cause of fatal injuries among workers.* In 2013, workers' compensation costs for serious, nonfatal injuries among work-related roadway incidents involving motorized land vehicles were estimated at $2.96 billion.(†) Seat belt use is a proven method to reduce injuries to motor vehicle occupants (1). Use of lap/shoulder seat belts reduces the risk for fatal injuries to front seat occupants of cars by 45% and the risk to light truck occupants by 60%.(§) To characterize seat belt use among adult workers by occupational group, CDC analyzed data from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) and found that not always using a seat belt was significantly associated with occupational group after controlling for factors known to influence seat belt use. Occupational groups with the highest prevalences of not always using a seat belt included construction and extraction; farming, fishing, and forestry; and installation, maintenance, and repair. To increase seat belt use among persons currently employed, states can enact and enforce primary seat belt laws, employers can set and enforce safety policies requiring seat belt use by all vehicle occupants, and seat belt safety advocates can target interventions to workers in occupational groups with lower reported seat belt use.

    As part of a study on health effects of naphtha exposure, the association between naphtha exposure and urinary excretion of total protein, albumin, beta-N-acetyl-D-glucosaminidase (beta-NAG), and beta 2-microglobulin was assessed prospectively over 1 year among workers at an automotive plant that used naphtha to calibrate fuel injectors. Participants consisted of 248 workers who provided spot urine samples in June 1988 among whom 181 workers provided specimens again in June 1989. Naphtha air concentrations at the plant ranged from 6 to 790 mg/m3 and the length of exposure ranged from 0.8 to 7.3 years. In both 1988 and 1989, the overall distribution of the four measures of renal function appeared consistent with that of an unexposed population. In cross-sectional analyses, there were no statistically significant associations in the expected direction between cumulative or recent naphtha exposure and the measures of renal function. In longitudinal analyses, the change in beta-NAG was positively associated with the change in recent naphtha exposure (P = .009). The effect of the naphtha exposure during 1 workweek was assessed among 17 workers who provided urine samples Monday preshift, Monday postshift, and Friday postshift. No associations were found. The results of this study do not provide strong evidence of naphtha-associated renal effects at these levels of exposure.

    Cancer risk in secondary aluminium production is not well described. Workers in this industry are exposed to potentially carcinogenic agents from secondary smelters that reprocess aluminium scrap. To evaluate cancer risk in workers in a secondary aluminium plant in Spain. Retrospective cohort study of male workers employed at an aluminium secondary smelter (1960-92). Exposure histories and vital status through 2011 were obtained through personal interviews and hospital records, respectively. Standardized mortality (SMRs) and incidence ratios (SIRs) were calculated. The study group consisted of 98 workers. We found increased incidence and mortality from bladder cancer [SIR = 2.85, 95% confidence interval (CI) 1.23-5.62; SMR = 5.90, 95% CI 1.58-15.11]. Increased incidence was also observed for prostate cancer and all other cancers but neither were statistically significant. No increased risk was observed for lung cancer. Results of this study suggest that work at secondary aluminium smelters is associated with bladder cancer risk. Identification of occupational carcinogens in this industry is needed. © The Author 2016. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

    Latino migrant farm workers suffer significant health disparities, including poor oral health. The purpose of this research was to assess Latino migrant farm workers' OC awareness, including knowledge and care-seeking behaviors. A 42-item survey was developed. Trained, bilingual researchers verbally administered the survey to migrant farm workers in Hillsborough County, Florida. Frequencies and descriptive statistics were generated to report baseline data. The sample consisted of 53.7 % female respondents. The mean age for males and females respectively was 38.7 and 39.2. Most respondents had attended grade school; 6.7 % never attended school. Perceptions of cancer susceptibility were present; knowledge of OC risk factors, signs and symptoms was low. Participants were unlikely to seek preventive care. The results contribute to the limited studies regarding Latino migrant farm workers and oral cancer risk factor awareness and knowledge. Findings highlight factors influencing motivation and care-seeking behaviors, as well as provide guidance for development of educational materials.

    2017-09-01

    Direct care workers in long-term care can develop close relationships with their patients and subsequently experience significant grief after patient death. Consequences of this experience for employment outcomes have received little attention. To investigate staff, institutional, patient, and grief factors as predictors of burnout dimensions among direct care workers who had experienced recent patient death; determine which specific aspects of these factors are of particular importance; and establish grief as an independent predictor of burnout dimensions. Participants were 140 certified nursing assistants and 80 homecare workers who recently experienced patient death. Data collection involved comprehensive semistructured in-person interviews. Standardized assessments and structured questions addressed staff, patient, and institutional characteristics, grief symptoms and grief avoidance, as well as burnout dimensions (depersonalization, emotional exhaustion, and personal accomplishment). Hierarchical regressions revealed that grief factors accounted for unique variance in depersonalization, over and above staff, patient, and institutional factors. Supervisor support and caregiving benefits were consistently associated with higher levels on burnout dimensions. In contrast, coworker support was associated with a higher likelihood of depersonalization and emotional exhaustion. Findings suggest that grief over patient death plays an overlooked role in direct care worker burnout. High supervisor support and caregiving benefits may have protective effects with respect to burnout, whereas high coworker support may constitute a reflection of burnout.

    Full Text Available Objectives. To study the associations between exposure to bioaerosols and work-related symptoms, lung function and biomarkers of airway inflammation in compost workers. Materials and method. Personal full-shift exposure measurements were performed on 47 workers employed at five windrow plants (n=20 and five reactor plants (n=27. Samples were analyzed for endotoxins, bacteria, fungal and actinomycetes spores. Health examinations were performed on workers and 37 controls before and after work on the day exposure was measured. The examinations included symptoms recorded by questionnaire, lung function by spirometry and nasal dimensions by acoustic rhinometry (AR. The pneumoproteins CC16, SP-D and SP-A were measured in a blood sample drawn at the end of the day. Results.

However, windrow composting workers reported more symptoms than reactor composting workers, probably due to use of respiratory protection. Exposure-response relationships between actinomycetes spores exposure and respiratory effects, found as cough and nose irritation during a shift, was significantly increased (OR 4.3, 95% CI 1.1–16, OR 6.1, 95% CI 1.5–25, respectively, p<0.05 among workers exposed to 0.02–0.3 × 10[sup]6[/sup] actinomycetes spores/m 3 , and FEV1/FVC% decreased cross shift (b=–3.2, SE=1.5%, p<0.01. Effects were weaker in the highest exposed group, but these workers used respiratory protection, frequently limiting their actual exposure. No relationships were found between exposure and pneumoprotein concentrations. Conclusions. The major agent in the aerosol generated at compost plants was actinomycetes spores which was associated with work related cough symptoms and work

    The increasing use of temporary work prompts the need to understand to what degree workers with this type of contract differ from permanent workers as to the relationship they establish with the organization they work for. This study used a sample of temporary workers (N = 78) and permanent workers (N = 196) within the same company of electronics in Portugal. The results show that, regardless of the type of contract, the perception of human resource practices was related to the perception of psychological contract fulfillment by the company. Additionally and according to the norm of reciprocity, we verified that when workers thought the company was fulfilling its obligations they responded favorably showing more affective commitment towards the company. However, we found differences between these two groups of workers: for the permanent performance appraisal, training and rewards were human resources practices that were significantly related to psychological contract fulfillment, while for the temporary ones there weren't any specific practices that had a significant relationship with that variable. The practical implications of these findings for the management of temporary workers are discussed.

    Full Text Available A study was conducted in beauty parlor workers of Lucknow, India, to assess the prevalence of respiratory morbidity and lung function abnormalities compared to their control subjects belonging to the same socioeconomic status and ethnic group, having never been exposed to the workplace of beauty parlor and having not used any cosmetics. Respiratory morbidity and bronchial obstruction based on PEFR study was conducted in 196 beauty parlor workers and 35 control subjects. All the participants were non-smokers and were matched for age, height, weight and socioeconomic status. Peak expiratory flow rate were performed using Peak Flow meter. Symptomatic workers showed bronchial obstruction (28%, and this prevalence was significantly higher ( P P < 0.01 than male workers (1.42. Overall respiratory morbidity among beauty parlor workers showed higher (12.7% when compared with control group (2.8% but differences couldn′t attain any significance. Although nonsignificant, workers in beauty parlor showed more prevalence (9.4% of bronchial obstruction based on PEFR than controls (4%. This study showed that beauty parlor workers were more prone to respiratory morbidity and lung function abnormalities, as the study group selected were non-smokers.

    Full Text Available The issue of migrant live-in homecare workers has been barely addressed in the gerontological literature, in spite of the increase of older persons being cared for by such persons in many Western countries. The purposes of the study are to examine the extent to which migrant live-in homecare workers substitute family caregivers or complement the care that is provided by primary caregivers, and to examine if there are differences in primary caregivers’ involvement in providing help with activities of daily living (ADL and instrumental activities of daily living (IADL before and after hiring a migrant live-in homecare worker, by caregivers’ employment status and gender. The data were drawn from a study that included 335 triads (care recipients, their primary caregivers, and their Filipina live-in homecare workers. The findings show that for the most part primary caregivers continue to play a significant role in providing care, in particular with regard to IADL tasks, even when there is a migrant live-in homecare worker. Several patterns of division of labor between the formal and informal caregivers were identified; that is, in some cases they complement each other while in other cases the migrant live-in homecare workers substitute for the care previously provided by the primary caregivers. Significant differences between male and female caregivers and between working and nonworking caregivers were found with regard to involvement in providing care before and after employment of a migrant homecare worker.

    In our research project entitled 'Chemical irritative and/or genotoxic effect of fumes of bitumen under high processing temperatures on the airways,' 73 mastic asphalt workers exposed to fumes of bitumen and 49 construction nonexposed workers were analyzed and compared with respect to polycyclic aromatic hydrocarbons (PAHs) exposure and exposure-related health effects. In order to assess the internal exposure the monohydroxylated metabolites of pyrene, 1-hydroxypyrene (1-OHP), and phenanthrene, 1-, 2- and 9-, and 3- and 4-hydroxyphenanthrene (OHPH) were determined in pre- and post-shift urinary samples. Significantly higher concentrations 1-OHP and OHPH were detected in the post-shift urine samples of 7 mastic asphalt workers working on the same construction site compared to the reference workers and all other 66 mastic asphalt workers. The adjusted mean OHPH in the reference, 66 mastic worker, and 7 worker subgroups was 1022, 1544, and 12919 ng/g creatinine (crn) respectively, indicating a marked rise in the 7 worker subgroup. In addition, there was a more than 12-fold increase of PAH metabolites from pre- to post-shift in these 7 workers, whereas in the other mastic asphalt workers there was only a twofold rise in PAH-metabolite concentration between pre- and post-shift values. The analysis of a drilling core from the construction site of the seven workers led to the detection of the source for this marked PAH exposure during the working shift as being coal tar plates, which were, without knowledge of the workers and coordinators, the underground material of the mastic asphalt layer. The evaluation of the stationary workplace concentration showed enhanced levels of phenanthrene, pyrene, fluorene, anthracene, and acenaphthene during working shifts at the construction site of these seven workers. Our study shows that biological monitoring is also a useful tool for the detection of unrecognized sources with high PAH concentrations.

    Full Text Available Background: With the rising of baking industries in Bangladesh, more female workers are surprisingly engaged compared to male workers. The major aim of this study was to observe the working conditions, available safety facilities and hygiene maintained by the female workers.Methods: A cross sectional survey was carried out among the randomly selected 384 female workers from different baking industries located at Dhaka and Tangail regions in Bangladesh by a well-designed semi-structured questionnaire.Results: About 33% of all respondents opined the machine room was congested, 27% narrow packaging and sealing room while 37% unhealthy storage areas. Two industries did not have proper accident prevention facilities. Although all the industries had monitoring personnel hygiene practices, about 40% of the workers were found not strictly maintaining some basic personal hygiene criteria. Socio-demographic result showed that the workers education level and monthly family income were poor. About 59.1% of all workers were suffering from various degrees of Chronic Energy Deficiencies (CED. It was also observed that nutritional status of the workers significantly related to their expenditure of the foods and working loads (χ2 Value < 0.05.Conclusion: The survey revealed that the occupational hygiene and safety practices were not at satisfactory level in some selected food industries in Bangladesh. The currently available food safety tools and system like Hazard Analysis and Critical Control Points (HACCP should be adapted by the industries and concurrently ensure the sufficient wages for workers. Keywords: Industrial female workers, Occupational hygiene, Safety practices, Chronic Energy Deficiencies (CED

    Female sex trade workers are among those at highest risk for developing and dying of cervical cancer, and yet many-particularly the most marginalized-are less likely than other women to be screened. This review summarizes global findings on innovative approaches to cervical cancer screening for female sex trade workers, highlights current gaps in the delivery of cervical cancer screening for female sex trade workers globally, and suggests areas for future research and policy development. A scoping review of peer-reviewed publications and grey literature was conducted. Medline (OVID), PubMed, EMBASE, and SCOPUS were searched for relevant studies written in English. There were no limitations placed on dates. Grey literature was identified by hand searching and through discussion with health care providers and community outreach workers currently working with sex trade workers. Twenty-five articles were deemed suitable for review. Articles detailing innovative ways for female sex trade workers to access cervical cancer screening were included. Articles about screening for sexually transmitted infections were also included if the findings could be generalized to screening for cervical cancer. Articles limited to exploring risk factors, knowledge, awareness, education, prevalence, and incidence of cervical cancer among sex trade workers were excluded from the review. Successful screening initiatives identified in the studies reviewed had unconventional hours of operation, understood the difference between street-based and venue-based sex trade workers, and/or used peers for outreach. Two significant gaps in health care service delivery were highlighted in this review: the limited use of unorthodox hours and the nearly exclusive practice of providing sexually transmitted infection screening for female sex trade workers without cervical cancer screening. In addition, although street-based (as opposed to venue-based) sex trade workers are likely at higher risk for

    Background It has been suggested that dust exposure causes airway inflammation among cement factory workers. However, there is limited information on the mechanisms of this effect. We explored any associations between total dust exposure and fractional exhaled nitric oxide (FENO) as a marker of airway eosinophilic inflammation among cement production workers in Tanzania. We also examined possible differences in FENO concentration between workers in different parts of the production line. Methodology We examined 127 cement workers and 28 controls from a mineral water factory. An electrochemistry-based NIOX MINO device was used to examine FENO concentration. Personal total dust was collected from the breathing zone of the study participants using 37 mm cellulose acetate filters placed in three-piece plastic cassettes. Interviews on workers’ background information were conducted in the Swahili language. Results We found equal concentrations of FENO among exposed workers and controls (geometric mean (GM)=16 ppb). The GM for total dust among the exposed workers and controls was 5.0 and 0.6 mg/m3, respectively. The FENO concentrations did not differ between the exposed workers with high (GM≥5 mg/m3) and low (GM<5 mg/m3) total dust exposure. There was no significant difference in FENO concentration between workers in the two main stages of the cement production process. Conclusions We did not find any difference in FENO concentration between dust-exposed cement workers and controls, and there were similar FENO concentrations among workers in the two main stages of cement production.

    In order to know the changes of genetic toxicological effects on workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs), sister chromatic exchange(SCE) was detected by the methods of peripheral lymphocyte culture in 23 workers exposed to coal tar pitch (CTP) and in 19 workers exposed to coke oven volatiles (COV) and 12 normal controls. The results suggested that the SCE in occupational workers was significantly higher than that in controls (11.31 vs 6.37, P 0.05). It is indicated that CTP and COV caused strong genetic toxicity and injury to chromosome.

    Identification of motor vehicle crash (MVC) characteristics associated with thoracoabdominal injury would advance the development of automatic crash notification systems (ACNS) by improving triage and response times. Our objective was to determine the relationships between MVC characteristics and thoracoabdominal trauma to develop a torso injury probability model. Drivers involved in crashes from 1993 to 2001 within the National Automotive Sampling System were reviewed. Relationships between torso injury and MVC characteristics were assessed using multivariate logistic regression. Receiver operating characteristic curves were used to compare the model to current ACNS models. There were a total of 56,466 drivers. Age, ejection, braking, avoidance, velocity, restraints, passenger-side impact, rollover, and vehicle weight and type were associated with injury (p < 0.05). The area under the receiver operating characteristic curve (83.9) was significantly greater than current ACNS models. We have developed a thoracoabdominal injury probability model that may improve patient triage when used with ACNS.

  20. Anthropological significance of phenylketonuria.

    1975-01-01

    The highest incidence rates of phenylketonuria (PKU) have been observed in Ireland and Scotlant. Parents heterozygous for PKU in Norway differ significantly from the general population in the Rhesus, Kell and PGM systems. The parents investigated showed an excess of Rh negative, Kell plus and PGM type 1 individuals, which makes them similar to the present populations in Ireland and Scotlant. It is postulated that the heterozygotes for PKU in Norway are descended from a completely assimilated sub-population of Celtic origin, who came or were brought here, 1ooo years ago. Bronze objects of Western European (Scottish, Irish) origin, found in Viking graves widely distributed in Norway, have been taken as evidence of Vikings returning with loot (including a number of Celts) from Western Viking settlements. The continuity of residence since the Viking age in most habitable parts of Norway, and what seems to be a nearly complete regional relationship between the sites where Viking graves contain western imported objects and the birthplaces of grandparents of PKUs identified in Norway, lend further support to the hypothesis that the heterozygotes for PKU in Norway are descended from a completely assimilated subpopulation. The remarkable resemblance between Iceland and Ireland, in respect of several genetic markers (including the Rhesus, PGM and Kell systems), is considered to be an expression of a similar proportion of people of Celtic origin in each of the two countries. Their identical, high incidence rates of PKU are regarded as further evidence of this. The significant decline in the incidence of PKU when one passes from Ireland, Scotland and Iceland, to Denmark and on to Norway and Sweden, is therefore explained as being related to a reduction in the proportion of inhabitants of Celtic extraction in the respective populations.

    Full Text Available Abstract Background Migrant workers are a unique phenomenon in the process of China's economic transformation. The household registration system classifies them as temporary residents in cities, putting them in a vulnerable state with an unfair share of urban infrastructure and social public welfare. The amount of pressure inflicted by migrant workers in Beijing, as one of the major migration destinations, is currently at a threshold. This study was designed to assess the factors associated with health-seeking behavior and to explore feasible solutions to the obstacles migrant workers in China faced with when accessing health-care. Methods A sample of 2,478 migrant workers in Beijing was chosen by the multi-stage stratified cluster sampling method. A structured questionnaire survey was conducted via face-to-face interviews between investigators and subjects. The multilevel methodology (MLM was used to demonstrate the independent effects of the explanatory variables on health seeking behavior in migrant workers. Results The medical visitation rate of migrant workers within the past two weeks was 4.8%, which only accounted for 36.4% of those who were ill. Nearly one-third of the migrant workers chose self-medication (33.3% or no measures (30.3% while ill within the past two weeks. 19.7% of the sick migrants who should have been hospitalized failed to receive medical treatment within the past year. According to self-reported reasons, the high cost of health service was a significant obstacle to health-care access for 40.5% of the migrant workers who became sick. However, 94.0% of the migrant workers didn't have any insurance coverage in Beijing. The multilevel model analysis indicates that health-seeking behavior among migrants is significantly associated with their insurance coverage. Meanwhile, such factors as household monthly income per capita and working hours per day also affect the medical visitation rate of the migrant workers in Beijing

    Delaware is a leading US poultry-producing state, and foreign-born workers make up a significant percentage of those employed by Delaware's poultry plants. In Sussex County, Delaware, a high percentage of the poultry workers are from two countries with a high incidence of tuberculosis (TB), Mexico and Guatemala, and thus are at risk for TB infection and disease. Furthermore, their risk of TB may be increased because many of these workers live in crowded conditions and lack access to medical care.

The aim of this study has been to evaluate the HRV differences in winter and in summer in the case of the Ministry of the Russian Federation for Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters (EMERCOM workers and scientific workers from the Komi Science Center of the Ural Branch of the Russian Academy of Sciences. Material and Methods: The short-term HRV was examined for 13 EMERCOM workers and 13 scientific workers. The data was collected in winter (December and summer (July for the same groups of workers. The time domain and frequency domain HRV analyses were performed. The EMERCOM workers had more contact with the external environment than the scientific workers. Results: The two-way analysis of variance with repeated observations on a single factor has shown that “Season” and interaction of two factors “Season” and “Profession” significantly influenced the HRV among volunteers. The “Profession” factor did not influence the HRV parameters (except for the heart rate in winter, p = 0.042. Seasonal changes in the HRV parameters were not significant in the case of scientific workers. In contrast, the EMERCOM workers showed significantly decreased parameters of parasympathetic activity (the root-mean-square of successive differences in RR intervals, percentage of consecutive RR intervals differing by > 50 ms and the relative value high frequency power, p = 0.001, p = 0.014 and p = 0.009, respectively and increased parameters of sympathetic activity (the stress index and ratio of low-frequency power to high-frequency power, p = 0.012 and p = 0.006, respectively in winter as compared to summer.

    This study was aimed to examine the association between the effective radiation dose of diagnostic radiation workers in Korea and their risk for cancer. A total of 36,394 diagnostic radiation workers (159,189 person-years) were included in this study; the effective dose and cancer incidence were analyzed between the period 1996 and 2002. Median (range) follow-up time was 5.5 (0.04-7) years in males and 3.75 (0.04-7) years in females. Cancer risk related to the average annual effective dose and exposure to more than 5 mSv of annual radiation dose were calculated by the Cox proportional hazard model adjusted for occupation and age at the last follow-up. The standardized incidence ratio of cancer in radiation workers showed strong healthy worker effects in both male and female workers. The relative risk of all cancers from exposure of the average annual effective dose in the highest quartile (upper 75% or more of radiation dose) was 2.14 in male workers (95% CI: 1.48-3.10, p-trend: <0.0001) and 4.43 in female workers (95% CI: 2.17-9.04, p-trend: <0.0001), compared to those in the lower three quartiles of radiation exposure dose (less than upper 75% of radiation dose). Cancer risks of the brain (HR: 17.38, 95% CI: 1.05-287.8, p-trend: 0.04) and thyroid (HR: 3.88, 95% CI: 1.09-13.75, p-trend: 0.01) in female workers were significantly higher in the highest quartile group of radiation exposure compared to those in the lower three quartiles, and the risk of colon and rectum cancers in male workers showed a significantly increasing trend according to the increase of the average annual radiation dose (HR: 2.37, 95% CI: 0.99-5.67, p-trend: 0.02). The relative risk of leukemia in male workers and that of brain cancer in female workers were significantly higher in the group of people who had been exposed to more than 5 mSv/year than those exposed to less than 5 mSv/year (HR: 11.75, 95% CI: 1.08-128.20; HR: 63.11, 95% CI: 3.70-1,075.00, respectively).

    Home care visits can last several hours. Home care workers are often at a loss on how to fill time spent in homes of clients. The challenge is how to use this time in ways that are productive and engaging for both clients and home health workers. The authors trained home health aides to implement Montessori-based activities while interacting with clients who have dementia. The results were amazing. Among other positive results, the authors found a statistically significant increase in the amount of pleasure displayed by clients after health workers received training.

    This is the first study to examine direct service worker turnover and its predictors across three provider types: nursing homes, home health agencies, and providers of services for the developmentally disabled. Stratified random sampling procedures were used to select provider types across five geographic regions in Ohio. Data were collected from administrative staff. Findings indicated that annual direct service worker turnover did not significantly vary by provider type (mean = 33%). Predictors of turnover related to job burnout, negative social support, and region. Policymakers can promote practices to lower direct service worker turnover such as addressing burnout and increasing support.

    This retrospective study was conducted to determine the pregnancy outcomes and identify predictive factors of adverse outcomes in pregnant migrant workers who delivered at Songklanagarind Hospital from January 2002 to December 2012. Two hundred and forty migrant worker pregnancies were enrolled. Pre-eclampsia, gestational diabetes mellitus, pre-term birth and foetal intrauterine growth restriction found were 15, 7.9, 13.7 and 3.7%, respectively. No stillbirth was found. Apgar score was significantly related to increased risk of overall adverse maternal outcomes. Only pre-term birth was significantly related to overall adverse neonatal outcomes.

    Foreign domestic helpers constitute a significant proportion of migrant workers worldwide. This population subgroup provides an opportunity for understanding social determinants of oral health in immigrant community. A random sample of 122 Indonesian domestic helpers in Hong Kong completed a questionnaire on their demographic background, social characteristics (competency in local languages, immigration history, living condition, social connections, and leisure activities) and oral health behaviours (knowledge, attitudes, practice and self-efficacy). Their tooth status and periodontal health were assessed. Participants tended to start flossing after settling in Hong Kong. Favourable oral health knowledge was found in more acculturated participants, as indicated by proficiency in local languages and immigration history. Engagement in social and/or religious activities and decent living condition provided by employers were associated with favourable oral health behaviours and/or better oral health. Social determinants explained 13.2 % of variance in caries severity. Our findings support the significant impact of social circumstances on oral health of domestic workers.

    Full Text Available The concept of "public accountability" is a challenge for political science as a new concept in this area in full debate and developement ,both in theory and practice. This paper is a theoretical approach of displaying some definitions, relevant meanings and significance odf the concept in political science. The importance of this concept is that although originally it was used as a tool to improve effectiveness and eficiency of public governance, it has gradually become a purpose it itself. "Accountability" has become an image of good governance first in the United States of America then in the European Union.Nevertheless,the concept is vaguely defined and provides ambiguous images of good governance.This paper begins with the presentation of some general meanings of the concept as they emerge from specialized dictionaries and ancyclopaedies and continues with the meanings developed in political science. The concept of "public accontability" is rooted in economics and management literature,becoming increasingly relevant in today's political science both in theory and discourse as well as in practice in formulating and evaluating public policies. A first conclusin that emerges from, the analysis of the evolution of this term is that it requires a conceptual clarification in political science. A clear definition will then enable an appropriate model of proving the system of public accountability in formulating and assessing public policies, in order to implement a system of assessment and monitoring thereof.

    Immigrant workers are a vulnerable and underserved population. The average life expectancy of the migrant worker is 49 years, compared to 77.2 years for most Americans. Immigrant workers have a higher disease burden than other populations and work in occupations with high hazard levels. In addition, they have low socioeconomic levels and face many barriers to accessing healthcare services. Undocumented immigrant workers are excluded in the Affordable Care Act. Health professionals must be attuned to the health issues of new immigrants so that they can provide better services. In order to raise the health standards of America, health professionals must provide healthcare for all, including immigrant workers.

    Full Text Available Background: India, a land of agriculture, has formed the scaffolding for many agro-based industries. Morbidity is more common among these industrial workers; hence, this study was conducted. Objectives: To study the morbidity pattern among the rice mill workers and the relationship between duration (years of working and their morbid status. Study Design: A cross-sectional study. Materials and Methods: A pre-structured questionnaire was used to record the necessary information such as clinical history, sociodemographic profile, findings of clinical examination and performance of peak expiratory flow rate (PEFR. The study was conducted in three rice mills in an urban area under Urban Health Training Centre (UHTC, Department of Community Medicine, SSMC, Tumkur. A total of 75 workers were recruited for the study. The study was conducted in the month of October. Statistical analysis was done using Chi-square test. Results: Among these 75 workers, 42.66% had respiratory morbidity; among them, 10.66% had PEFR less than 200L/min. 26.66% had low backache and knee joint pain and 20% had generalized / musculo skeleton pain. 6.6% suffered from allergic conjunctivitis and 4% had skin allergy. Conclusion: High Prevalence of respiratory morbidity (42.66% and 8 (10.66% workers with decreased PEFR were found. It also showed that there was statistically significant relationship between duration (years of working and respiratory morbid condition. This condition can be prevented by good health education and appropriate usage of safety devices, and further studies are recommended.

    2004-12-01

    Inadequate hand washing by food workers is an important contributing factor to foodborne disease outbreaks in retail food establishments (RFEs). We conducted a survey of RFEs to investigate the effect of hand washing training, availability of hand washing facilities, and the ability of the person in charge (PIC) to describe hand washing according to the Minnesota Food Code (food code) on workers' ability to demonstrate food code-compliant hand washing. Only 52% of the PICs could describe the hand washing procedure outlined in the food code, and only 48% of workers could demonstrate code-compliant hand washing. The most common problems observed were failure to wash for 20 s and failure to use a fingernail brush. There was a strong positive association between the PIC being a certified food manager and being able to describe the food code hand washing procedure (odds ratio [OR], 5.5; 95% confidence interval [CI], 2.2 to 13.7), and there was an even stronger association between the PIC being able to describe hand washing and workers being able to demonstrate code-compliant hand washing (OR, 15; 95% CI, 6 to 37). Significant associations were detected among correct hand washing demonstration, physical infrastructure for hand washing, and the hand washing training methods used by the establishment. However, the principal determinant of successful hand washing demonstration was the PIC's ability to describe proper hand washing procedure. These results suggest that improving hand washing practices among food workers will require interventions that address PIC knowledge of hand washing requirement and procedure and the development and implementation of effective hand washing training methods.

    Liquefied petroleum gas (LPG) is widely used in the Gaza Strip for domestic purposes, in agriculture and industry and, illegally, in cars. This study aimed to identify possible health effects on workers exposed to LPG in Gaza governorates. Data were collected by a questionnaire interview, and haematological and biochemical analyses of venous blood samples were made from 30 workers at filling and distribution stations and 30 apparently healthy controls. Statistically significant differences were found in all self-reported health-related complaints among LPG workers versus controls. LPG workers had significantly higher values of red blood cell counts, haemoglobin, haematocrit mean corpuscular haemoglobin and platelet counts. They also had significantly higher values of kidney function tests (urea, creatinine and uric acid) and liver function enzyme activities (aspartate aminotransferase and alanine aminotransferase). LPG workers at Gaza Strip petroleum stations are at higher risk for health-related symptoms and clinical abnormalities.

    Social capital is important to disadvantaged groups, such as sex workers, as a means of facilitating internal group-related mutual aid and support as well as access to broader social and material resources. Studies among sex workers have linked higher social capital with protective HIV-related behaviors; however, few studies have examined social capital among sex workers in sub-Saharan Africa. This cross-sectional study examined relationships between two key social capital constructs, social cohesion among sex workers and social participation of sex workers in the larger community, and HIV-related risk in Swaziland using respondent-driven sampling. Relationships between social cohesion, social participation, and HIV-related risk factors were assessed using logistic regression. HIV prevalence among the sample was 70.4% (223/317). Social cohesion was associated with consistent condom use in the past week (adjusted odds ratio [AOR] = 2.25, 95% confidence interval [CI]: 1.30-3.90) and was associated with fewer reports of social discrimination, including denial of police protection. Social participation was associated with HIV testing (AOR = 2.39, 95% CI: 1.36-4.03) and using condoms with non-paying partners (AOR = 1.99, 95% CI: 1.13-3.51), and was inversely associated with reported verbal or physical harassment as a result of selling sex (AOR = 0.55, 95% CI: 0.33-0.91). Both social capital constructs were significantly associated with collective action, which involved participating in meetings to promote sex worker rights or attending HIV-related meetings/ talks with other sex workers. Social- and structural-level interventions focused on building social cohesion and social participation among sex workers could provide significant protection from HIV infection for female sex workers in Swaziland.

    The "Just-in-Time system" improves productivity and efficiency through cost reduction while it makes workers work in a standing posture. The aim of this study was to investigate the prevalence of postural hypotension in females during prolonged standing work, and to discuss preventive methods. Twelve female static standing workers (mean age+/-standard deviation; 32+/-14 yr old), 6 male static standing workers (30+/-4 yr old), 10 female walking workers (27+/-7 yr old) and 9 female desk workers (31+/-5 yr old) in a certain telecommunications equipment manufacturing factory agreed to participate in this study. All participants received an interview with an occupational physician, and performed the standing up test before working and ambulatory blood pressure monitoring (ABPM) while working. Although the blood pressure of the standing up test did not differ among the groups, mean pulse rates on standing up significantly increased in every group. Hypotension rates in the female standing workers' group by ABPM were 9 persons of 12 participants (75%) for systolic blood pressure (SBP), and were 11 persons of 12 participants (92%) for diastolic blood pressure (DBP). There were significantly higher than those in the female desk workers' group, none of 9 participants (0%) for SBP and 2 of 9 participants (22%) for DBP. The hypotension rates both male standing and female walking worker groups did not differ. Because all 8 workers who were found to have postural hypotension by the standing up test had decreased SBP and/or DBP by ABPM, it is suggested that persons at high risk of postural hypotension during standing work could be screened by the standing up test. The mechanism of postural hypotension may be a decrease of venous return due to leg swelling, and neurocardiogenic or vasovagal response. Preventing the congestion of the lower limbs by walking, managing standing time and wearing elastic hose to keep the amount of the venous return could prevent postural hypotension

    This study examines the determinants of emotional laborers'--social workers in health care organizations--job satisfaction and their public service motivation in using a structural equation model and provides empirical evidence regarding what contributes to job satisfaction or burnout in these workers. Among several latent variables, this study confirmed that false face significantly decreases the job satisfaction of social worker and is positively associated with burnout. In addition, commitment to public interest increases social workers' job satisfaction significantly. This study has implications for the management of emotional labor. By educating emotional laborers to reappraise situations to increase their job satisfaction and avoid burnout, reappraisal training and education are expected to result in increases in positive emotions and decreases in negative emotions, and to improve employees' performance in their organizations.

    Members of minority populations often have difficulty knowing about and accessing dementia services. One of the strategies used to promote access is the employment of bilingual/bicultural workers (sometimes referred to as multicultural, link or outreach workers). This study involved interviews with 24 bilingual/bicultural workers in south western Sydney, Australia to gain a better understanding of their role within the dementia field. Seven themes emerged: importance of working with family; process of building trust when moving between two cultures; importance of understanding the culture; self-care and culture; flexibility of their role; linking community members; and linking communities to mainstream services. Bilingual/bicultural workers play a significant and complex role in supporting individuals and families within their community who are affected by dementia. The significance of their role needs to be more clearly acknowledged in the development of policy, further research and service provision within the dementia field.

    The appearance of lumbal syndrome was analysed in two groups of workers in the "Zagrebacka pivovara" brewery. In a group of 23 workers whose mean age was 34 years and mean length of service 12 years, nine (39.1%) suffered from lumbal syndrome. In another group of 33 workers, with the mean age of 31 years and the mean length of service of nine years there were 24 (72.7%) suffering from the syndrome. According to Student's t-test the differences in age and length of service between the two groups were not significant (P > 0.05), but the difference in the number of ill was significant (P < 0.05). Analysis of the workplace showed that a heavy burden of the lumbal spine was involved, especially with the workers from the second group, and that ergonomic solutions were necessary.

    The aim of the study was to assess whether exposed workers had more subjective health complaints than controls 1 1/2 years after a chemical explosion involving a mixture of hydrocarbons and sulfurous compounds. A cross-sectional survey based on the Subjective Health Complaints Inventory (SHC) was conducted among 147 exposed workers and 137 controls. A significantly higher total SCH score (linear regression, p=.01) was found for the exposed workers compared with controls when adjusting for gender, age, smoking habits, and educational level. The exposed workers reported significantly more headache, hot flashes, sleep problems, tiredness, dizziness, and sadness/depression. The cause of these complaints is unknown, but health personnel should be aware that health complaints might be related to polluting episodes even when exposure levels are below occupational guideline levels.

    Full Text Available Abstract Background In the past decade flexible labour market arrangements have emerged as a significant change in the European Union labour market. Studies suggest that these new types of labour arrangements may be linked to ill health, an increased risk for work disability, and inadequate vocational rehabilitation. Therefore, the objectives of this study were: 1. to examine demographic characteristics of workers without an employment contract sick-listed for at least 13 weeks, 2. to describe the content and frequency of occupational health care (OHC interventions for these sick-listed workers, and 3. to examine OHC interventions as possible determinants for return-to-work (RTW of these workers. Methods A cohort of 1077 sick-listed workers without an employment contract were included at baseline, i.e. 13 weeks after reporting sick. Demographic variables were available at baseline. Measurement of cross-sectional data took place 4–6 months after inclusion. Primary outcome measures were: frequency of OHC interventions and RTW-rates. Measured confounding variables were: gender, age, type of worker (temporary agency worker, unemployed worker, or remaining worker without employment contract, level of education, reason for absenteeism (diagnosis, and perceived health. The association between OHC interventions and RTW was analysed with a logistic multiple regression analysis. Results At 7–9 months after the first day of reporting sick only 19% of the workers had (partially or completely returned to work, and most workers perceived their health as fairly poor or poor. The most frequently reported (49% intervention was 'the OHC professional discussed RTW'. However, the intervention 'OHC professional made and discussed a RTW action plan' was reported by only 19% of the respondents. The logistic multiple regression analysis showed a significant positive association between RTW and the interventions: 'OHC professional discussed RTW'; and 'OHC

    Dental amalgam in fillings exposes workers to mercury. The exposure to mercury was investigated among 1871 dental health care workers. The aim of the study was to evaluate the risk of mercury exposure among dental compared to nondental health care workers and to determine other risk factors for mercury exposure. Respondents answered questionnaires to obtain demographic, personal, professional, and workplace information and were examined for their own amalgam fillings. Chronic mercury exposure was assessed through urinary mercury levels. In total, 1409 dental and 462 nondental health care workers participated in the study. Median urine mercury levels for dental and nondental health care workers were 2.75 μg/L (interquartile range [IQR] = 3.0175) and 2.66 μg/L (IQR = 3.04) respectively. For mercury exposure, there were no significant risk factor found among the workers involved within the dental care. The Mann-Whitney test showed that urine mercury levels were significantly different between respondents who eat seafood more than 5 times per week compared to those who eat it less frequently or not at all (p = 0.003). The urinary mercury levels indicated significant difference between dental workers in their practice using squeeze cloths (Mann-Whitney test, p = 0.03). Multiple logistic regression showed that only the usage of cosmetic products that might contain mercury was found to be significantly associated with the urinary mercury levels (odds ratio [OR] = 15.237; CI: 3.612-64.276). Therefore, mean urinary mercury levels of health care workers were low. Exposure to dental amalgam is not associated with high mercury exposure. However, usage of cosmetic products containing mercury and high seafood consumption may lead to the increase of exposure to mercury.

  15. A Different Class of Care: the Benefits Crisis and Low-Wage Workers.

    Science.gov (United States)

    Jones, Trina

    When compared to other developed nations, the United States fares poorly with regard to benefits for workers. While the situation is grim for most U.S. workers, it is worse for low-wage workers. Data show a significant benefits gap between low-wage and high-wage in terms of flexible work arrangements (FWAs), paid leave, pensions, and employer-sponsored health-care insurance, among other things. This gap exists notwithstanding the fact that FWAs and employment benefits produce positive returns for employees, employers, and society in general. Despite these returns, this Article contends that employers will be loath to extend FWAs and greater employment benefits to low-wage workers due to (1) concerns about costs, (2) a surplus of low-wage workers in the labor market, (3) negative perceptions of the skill of low-wage workers and the value of low-wage work, (4) other class-based stereotypes and biases, and (5) structural impediments in some low-wage jobs. Given the decline of unions and limited legislative action to date, the Article maintains that low-wage workers are in a "different class of care" with little hope for meaningful change on the horizon.

    Full Text Available Abstract Background In low income countries, the task of providing primary health care is often the responsibility of community health workers. In Pakistan, community workers called Lady Health Workers (LHW deliver basic health care at the doorstep in the rural areas and urban slums. Evaluations show that it is a successful programme but point out inconsistencies in the quality of service provided. In order achieve this, it would be important to obtain the workers' viewpoint on their job-description, the problems they face and the levels of stress they encounter. Methods We conducted a multi-method study to investigate the aforementioned issues. All LHWs from one typical rural sub-district in Rawalpindi were surveyed. Focus group discussions with a sub-set of these workers were also conducted. Results About a quarter of the LHWs were found to have significant occupational stress. Factors associated with stress included having low socio-economic status and having to travel long distances for work. Inconsistent medical supplies, inadequate stipends, lack of career structure and not being equipped to communicate effectively with families were the main factors for job dissatisfaction among these workers. Recommendations Improvement in remuneration, better administration of supplies and a structured career path should be ensured for better performance of community health workers. In addition, communication skills learning should be an essential part of their training programme.

    Honey bees (Apis mellifera carnica Pollm.) have low glycogen reserves in summer. Upon emergence drones have significantly larger amounts per unit weight when emerging, than workers; perhaps as adaption to the risk of not being fed as intensely as young workers. Maximum content was 0.23mg for workers (28d), and 0.59mg for drones (after emergence). Workers have relatively constant glycogen contents during their life, and very young drones have more glycogen than older ones. Young queens are similar to workers. In workers and queens in summer the greatest amounts of glycogen are found in the thorax. When the bees start flying (6th-8th day of life), drones have the highest amounts in the head (probably to supply their eyes), and upon maturity, drones have the least glycogen in the abdomen.Workers in winter show different glycogen values depending on whether they are active bees from the core area (0.23mg) or inactive ones from the outer surface of the winter cluster (0.37mg). They use glycogen from the thorax and the abdomen for their ongoing energy need.

    The purpose of this study was to determine the personal factors and working conditions that predict work injuries among industrial workers. To fulfill this aim, a case control study was conducted including 2003 industrial workers who sustained a work injury and an equal number of controls. All were subjected to an interview questionnaire to collect relevant information. Moreover, records were reviewed to obtain the medical history of enrolled workers. Data revealed that workers in the index and control groups are comparable in respect to their sociodemographic characteristics. The multivariate logistic regression analysis pointed out that safety training significantly reduces the risk of work accidents among industrial workers. On the other hand, work accidents are more likely to occur in the main working shift. Moreover, workers who suffer from chronic health problems calling for surgical treatment, as well as those who reported family problems, are more likely to experience work accidents. These workers should receive considerable attention to reduce the extent of work injuries. More importantly, safety-training programs are mandatory for accident prevention in industrial settings.

    Full Text Available Background: Brick manufacturing industry is one of the oldest and fast-growing industries in India that employs a large section of people. Brick kiln workers are occupationally exposed to air pollutants. Nonetheless, only a few studies have so far been conducted on their respiratory health. Objective: To investigate the extent of respiratory impairment in brick kiln workers and to correlate it with the duration of exposure. Methods: A cross-sectional study was conducted. Spirometric parameters of 110 non-smoking male brick kiln workers aged 18–35 years in Patiala district, Punjab, India, were compared with an age-matched comparison group of 90 unexposed individuals. Results: Brick kiln workers showed a significant (p8 years of exposure, the mean values of FEV1 (1.92 L, FVC (2.01 L, FEF25-75% (2.19 L/s and PEFR (4.81 L/s were significantly (p<0.05 lower than those recorded in workers with <8 years of exposure in whom the values were 2.01 L, 2.68 L, 2.71 L/s, and 5.76 L/s, respectively. Conclusion: There is a significant association between exposure to workplace pollutants and lung function deterioration among brick kiln workers.

    Full Text Available The present study investigates the functional integrity of liver among workers exposed to nickel during nickel-plating process. The functional integrity of liver was assessed in 69 workers who are exposed to nickel during nickel plating and considered as nickel-exposed workers; and 50 administrative workers residing in same city, but away from the place of work of study group, were considered as control group. The level of urine nickel was measured by using a flameless atomic absorption spectrophotometer. Using kits supplied by Bayer Diagnostics, we determined serum markers of liver function tests. Results: The levels of urine nickel were significantly increased in high-and moderate-exposure groups as compared to control group. The levels of serum transaminases -viz, alanine transaminase and aspartate transaminase-were significantly increased in nickel-exposed workers, who had high urine nickel levels as compared to control group. The level of serum albumin was negatively correlated with urine nickel levels. The levels of serum transaminases and serum g- glutamyl- transpeptidase were positively and significantly correlated with urine nickel levels. Conclusion: Results indicate that workers who had high urine nickel levels had a consistent effect on hepatic inflammatory function.

    Full Text Available BACKGROUND: Due to recent industrialization and inadequately protected workers or in other words poor supervision on constructive workers habits in our large city of Isfahan cement contact dermatitis is relatively high especially among cement factory workers and constructive personnel. PURPOSES: To investigate the prevalence rate of cement contact dermatitis in cement factory workers in Isfahan. METHODS: A case-control clinical study was carried out by randomly selecing 150 factory workders and 150 official clerks in a cement factory in Isfahan in 2001. After a complete physical examination, data was recorded in observational checklists. FINDINGS: The percentages of contact dermatitis prevalences in the first and the second groups were 22% and 5.3% respectively. About 60% of cement workers with contact dermatitis were between 30-40 years of age. There was a direct relationship with age in both groups of the workers. In the high-exposure group, the hand eczema along was 70% but in the other group the percentage of involvement was the same in exposed and unexposed anatomical areas. CONCLUSIONS: There was a direct relationship between occurrence and the severity of involvement and duration of contact in the first group. Cent percent of cement workers had contact dermatitis after 10 or less years, but the percentage among the other group was 35%. LIMITATION: Irritant contact dermatitis to cement has not been detected.

    High distress levels in healthcare workers in Japan may deteriorate safe service provision. To clarify job stress of healthcare workers, we compared Brief Job Stress Questionnaire (BJSQ) scores among physicians, nursing staff and administrative workers. Healthcare workers (n=9,137) in 20 hospitals in Japan were asked to answer BJSQ. BJSQ is job stress questionnaire to measure "Job Stressors", "Stress Responses" and "Social Supports". The "Total Health Risk" of the healthcare workers was 10% higher than the national average. While the physicians felt the stress of the quantitative and qualitative job overload, they had support from supervisors and coworkers and showed mild "Stress Responses". The nursing staff felt the stress of the quantitative and qualitative job overload at the same level as the physicians, but they did not have sufficient support from supervisors and coworkers, and showed high "Stress Responses". The administrative workers did not have sufficient support from supervisors and coworkers, but they experienced less stress as measured by the quantitative and qualitative job overload than the physicians or the nursing staff and showed moderate "Stress Responses". Further studies are needed to clarify the mechanisms and the influence of other factors to the stress trait in healthcare workers.

    Full Text Available Atmospheric benzene, toluene, ethylbenzene, and xylenes (BTEX can lead to multiple health injuries. However, what remains uncertain is the effect of long-term exposure to low levels of BTEX. Thus, we determined the BTEX levels in the air from the refueling and office areas in gas stations. Then we collected workers’ (200 refueling vs. 52 office workers peripheral blood samples to analyze the serum total-superoxide dismutase (T-SOD, glutathione (GSH, malondialdehyde (MDA, and 8-hydroxydeoxyguanosine (8-OHdG levels. DNA damage was analyzed by the comet assay and micronucleus test in buccal epithelial cells. We found that the levels of BTEX in refueling areas were significantly higher than those in office areas (p < 0.001. The serum T-SOD and GSH of refueling workers were significantly lower than those in office workers (p < 0.001. By contrast, the serum MDA and 8-OHdG of refueling workers were significantly higher than those of office workers (p < 0.001, MDA; p = 0.025, 8-OHdG. Furthermore, tail and Olive tail moments in refueling workers were longer (p = 0.004, tail moment; p = 0.001, Olive tail moment, and the micronucleus rate was higher (p < 0.001 than those in office workers. Taken together, long-term exposure to low levels of BTEX may reduce the antioxidant ability and increase the risk of DNA damage in refueling workers of gas stations.

    This study compares the prevalence of sexually transmitted diseases (STDs), condom use, and health-screening behavior between freelance and brothel-based sex workers in Singapore. A total of 111 female freelance sex workers arrested from November 1996 to March 1997 for illicit prostitution were interviewed; 333 brothel-based sex workers served as the comparison group for the analysis. STD test results revealed that freelance sex workers (34.8%) have higher STD rates than brothel-based sex workers (24%). The two most common STDs in both groups were chlamydial cervicitis and syphilis. Moreover, condom use was significantly lower among freelance sex workers than brothel-based sex workers and was associated with younger age (25 years old), decreasing number of clients, and perception of non-condom use among peers. In addition, freelance workers were more educated and had equally high knowledge on STDs and AIDS. Since most of these freelance workers practice high-risk behaviors and poor health screening behaviors such as not going for regular medical check-ups, STD services and education programs should target this group.

    1981-01-01

    Analyses of asbestos bodies from the general population have confirmed that these structures, like asbestos bodies from the lungs of asbestos workers, contain an asbestos core. In members of the general population this core is almost always an amphibole, whereas asbestos workers may have bodies formed on either amphibole or chrysotile. Most adults have a few bodies, and increasing numbers are seen in blue collar workers and others who handle small amounts of the fiber, with the highest levels being seen in asbestos workers. In men with minimal or extensive occupational exposure, asbestos bodies are formed on the commercial fibers, amosite and crocidolite, whereas women also form a significant number of bodies on the noncommercial fibers, anthophyllite and tremolite. These findings suggest that women may be exposed to specific asbestos-containing products, eg, cosmetic talc. The commercial fibers found in women and white collar men probably reflect atmospheric pollution with asbestos. At the highest levels of exposure, numbers of asbestos bodies correlate in a general way with the presence of asbestosis, although no precise value has been determined above which asbestosis is always found. In persons with much lower or environmental exposure, there does not appear to be any correlation between numbers of bodies and disease, in particular between numbers of bodies and carcinoma of the lung or gastrointestinal tract. The situation for mesothelioma is uncertain. Images Figure 1 Figure 2 Figure 3 PMID:6101235

    To identify common catalysts of worker-to-worker violence and incivility in hospital settings. Worker-to-worker violence and incivility are prevalent forms of mistreatment in healthcare workplaces. These are forms of counterproductive work behaviour that can lead to negative outcomes for employees, patients and the organisation overall. Identifying the factors that lead to co-worker mistreatment is a critical first step in the development of interventions targeting these behaviours. Retrospective descriptive study. Qualitative content analysis was conducted on the total sample (n = 141) of employee incident reports of worker-to-worker violence and incivility that were documented in 2011 at a large American hospital system. More than 50% of the incidents involved nurses, and the majority of incidents did not involve physical violence. Two primary themes emerged from the analysis: Work Behaviour and Work Organisation. Incidents in the Work Behaviour category were often sparked by unprofessional behaviour, disagreement over responsibilities for work tasks or methods of patient care, and dissatisfaction with a co-worker's performance. Incidents in the Work Organisation category involved conflicts or aggression arising from failure to following protocol, patient assignments, limited resources and high workload. Incidents of worker-to-worker violence and incivility stemmed from dissatisfaction with employee behaviour or from organisational practices or work constraints. These incident descriptions reflect worker dissatisfaction and frustration, resulting from poor communication and collaboration between employees, all of which threaten work productivity. Violence and incivility between hospital employees can contribute to turnover of top performers, hinder effective teamwork and jeopardise the quality of patient care. Identification of common catalysts for worker-to-worker violence and incivility informs the development of mistreatment prevention programmes that can be

    Full Text Available To date, shift workers represent between 15% and 25% of the modern day workforce. Work time poses a great challenge to workers as it requires that they balance productivity and sleep time between shifts. As a result, these workers experience chronic sleep deprivation with increased fatigue and drowsiness due to this sleep deprivation. The impact of this kind of work on the immune system is not yet known. We conducted a literature review with the aim of evaluating articles on this specific type of work's effects on sleep and immunity.

    Although tuberculosis (TB) has been recognized as a significant health problem of migrant farm workers, the nature and extent of the problem have been poorly defined. We report the first population-based study of TB in a random sample of farm workers (n = 543) and the first use of recall antigens in an epidemiologic study of TB. Purified protein derivative positivity ranged from 33% in Hispanics to 54% in US-born blacks and 76% in Haitians. Active tubercular disease occurred in 3.6% of US-born blacks and 0.47% of Hispanics. Among US-born blacks, risk factors associated with farm work were most significant. Blacks born in the United States also had the highest prevalence of anergy. The use of recall antigens made possible a better description of the epidemiology of TB by excluding false negatives and clarifying associations between infection and risk factors. We conclude that TB among farm workers represents a serious public health problem with previously unrecognized risk factors. Additional resources for migrant health care, improvements in health care access, and fundamental changes in the system of migrant labor are all necessary to reduce the transmission of TB.

    Examine trends and patterns of work-related musculoskeletal disorders (WMSDs) among construction workers in the USA, with an emphasis on older workers. WMSDs were identified from the 1992-2014 Survey of Occupational Injuries and Illnesses (SOII), and employment was estimated from the Current Population Survey (CPS). Risk of WMSDs was measured by number of WMSDs per 10 000 full-time equivalent workers and stratified by major demographic and employment subgroups. Time series analysis was performed to examine the trend of WMSDs in construction. The number of WMSDs significantly dropped in the US construction industry, following the overall injury trends. However, the rate of WMSDs in construction remained higher than in all industries combined; the median days away from work increased from 8 days in 1992 to 13 days in 2014, and the proportion of WMSDs for construction workers aged 55 to 64 years almost doubled. By occupation, construction labourers had the largest number of WMSD cases, while helpers, heating and air-conditioning mechanics, cement masons and sheet metal workers had the highest rates of WMSDs. The major cause of WMSDs in construction was overexertion, and back injuries accounted for more than 40% of WMSDs among construction workers. The estimated wage loss for private wage-and-salary construction workers was $46 million in 2014. Construction workers continue to face a higher risk of WMSDs. Ergonomic solutions that reduce overexertion-the primary exposure for WMSDs-should be adopted extensively at construction sites, particularly for workers with a higher risk of WMSDs.

    Discrimination based on type of employment against non-regular workers is still a social issue. However, there are few studies on job factors that affect the discrimination experience in each type of employment or the association between discrimination and health impact indicators. This study examined occupational health characteristics according to discrimination experience and relating factors that affect discrimination experience. This study used the 4th Korean Working Conditions Survey (2014) provided by the Korea Occupational Safety and Health Agency. Among the 50,000 workers, 7731 non-regular wage workers were selected as study population. To examine differences in discrimination experience, we used a t-test on occupational risk factors, occupational stress, occupational characteristics, health impact indicators. To identify the factors that affected discrimination experience, we performed binomial logistic regression analysis. The discrimination experience rate was significantly higher in male, aged less than 40 years old, above high school graduate than middle school graduate, higher wage level, shorter employment period and larger company's scale. As factors related to discrimination experience, they experienced discrimination more as occupational stress was higher and when they were temporary or daily workers rather than permanent workers, work patterns were not consistent, and the support of boss was low. It showed that physical, musculoskeletal, and mental occupational risk scores and subjective job instability were higher and work environment satisfaction was lower in discrimination experienced group. The present study showed that the demographic and occupational factors were complexly related to discrimination experience in non-regular workers. The experience of discrimination had increased when occupational stress was higher, they were temporary or daily workers rather than permanent workers, work patterns were not consistent, and their boss

    International debates on improving health system performance and quality of care are strongly coined by systems thinking. There is a surprising lack of attention to the human (worker) elements. Although the central role of health workers within the health system has increasingly been acknowledged, there are hardly studies that analyze performance and quality of care from an individual perspective.

    Sewage workers, because of their occupation, are exposed to different types of dusts, bio-aerosols, fumes and gases like methane, hydrogen sulfide, sulphur dioxide, etc, which contribute towards oxidative stress and detrimental effects on various body functions, especially lung functions. This study was carried out on sewage workers (who had been working for more than five years). We wanted to study the role of oxidative stress in development of impaired lung functions among sewage workers. This cross sectional study was done in a tertiary care hospital (J.N. Medical College) in Aligarh, U.P. Study was done from March 2008 to December 2009. The study group comprised of 62 sewage workers who had been working for more than five years (32 non-smokers and 30 smokers) and 60 control subjects (30 smokers and 30 non-smokers). The pulmonary functions of these workers were assessed by using a MIR (Medical International Lab) Spiro Lab II Spirometer, with subjects in sitting position. Valid written consents were obtained from all the subjects. Malondialdehyde (MDA) is produced as a result of the action of reactive oxygen species (ROS) on the lipids present in the membranes of the cells, especially, contracting muscle cells. Serum MDA levels were assessed as an indirect measure of oxidative stress in these sewage workers and they were compared with serum MDA levels of control subjects. Appropriate statistical tests were applied for analysis of the data which was generated. There were statistically significant decreases in Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in first second (FEV1) and FEV1/FVC percent ratio (workers as compared to those in control subjects (with a p-value of workers to harmful dust, fumes, gases and bio-aerosols contributed to oxidative stress among them. This oxidative stress was one of the mechanisms which led to the development of obstructive impairment of lung functions in these sewage workers.

    Full Text Available Background: Different types of sleep disturbances can have a serious negative effect on a person’s ability, function and overall well-being. One of the most important issues that can result in sleep disturbances are occupational causes, the most important among them is shift work. The objective of this study was to compare the prevalence of sleep disturbances between shift work and non-shift workers. Material and Methods: This study was designed as a case-control study in 196 shift workers and 204 non-shift workers in a textile factory. The data were collected by using a comprehensive questionnaire including Pittsburg Sleep Quality Index questionnaire, Berlin Questionnaire, Epworth Sleepiness Scale, Insomnia Severity Index and Restless Leg Syndrome Questionnaire. Data analyses were carried out using the SPSS software version 13 by student's t-test, Chi square and multiple logistic regressions. Results: The duration of night sleep in shift workers was less than day workers (p<0.001. Prevalence of poor sleep quality and insomnia were higher in shift workers significantly than non shift workers (p<0.001, OR=2.3 95% CI: 1.7-2.9. The most prevalent type of insomnia was problems in initiating sleep (P=0.022, OR=2.2 95% CI: 1.5-3.2. There was no difference in the prevalence of excessive day-time sleepiness, restless leg syndrome, snoring, obstructive sleep apnea and different types of parasomnias between two groups. Conclusion: Reduced length of sleep and higher prevalence of poor sleep quality and insomnia in shift workers emphasizes the importance of serious attention to sleep disorders in shift workers.

    The production and manufacture of microelectronic components, carried out primarily by women workers, require extensive use of organic solvents. Affective and personality disturbances frequently have been associated with organic solvent toxicity. A group of women, former microelectronics workers (N = 70), primarily of Hispanic origin (77.1%) but raised in the United States, were evaluated for affective and personality disturbance with the MMPI. Profiles were analyzed, and diagnostic classification was performed blind. Results showed that (1) 85.7% of the profiles indicated abnormally high clinical elevations; and (2) MMPI profile classification revealed four clinical diagnostic groups: somatoform (24.3%), depression (15.7%), anxiety (28.6%), and psychotic (14.3%). These findings indicate significant psychopathology among these women, who formerly had worked in a microelectronics plant. The patterns of impairment present similarities to previous reports of organic solvent toxicity.

    High-level occupational manganese (Mn) exposure has been reported to induce irreversible brain alterations determining a Parkinson-like disease. This study aimed to assess subclinical neurophysiological alterations in welding workers. They were employed in a machine building factory with an average Mn exposure rhythms significantly reduced, theta-waves markedly increased and abnormal wave activities of either localized or diffusive type. In the same workers BEAM revealed higher theta, delta and beta power values in the F7 area, lower d power values in the FP1, FP2 and C4 areas as well as dissymmetry in the central area, parietal region and occipital region. This study suggests that Mn impairs neuron activity within central nervous system. In this context, brainstem parasympathetic and sympathetic centers receiving axon projections from cortical and diencephalic areas, may reflect Mn effects on upper pathways. However, direct actions of Mn on these centers cannot be excluded.

    Rotator cuff integrity is critical to shoulder health. Due to the high workload imposed upon the shoulder while working in an industrial glovebox, this study investigated the strength ratio of the rotator cuff muscles in glovebox workers and compared this ratio to the healthy norm. Descriptive statistics were collected using a short questionnaire. Handheld dynamometry was used to quantify the ratio of forces produced in the motions of shoulder internal and external rotation. Results showed this population to have shoulder strength ratios that were significantly different from the healthy norm. The deviation from the normal ratio demonstrates the need for solutions designed to reduce the workload on the rotator cuff musculature of glovebox workers in order to improve health and safety. Assessment of strength ratios can be used to screen for risk of symptom development.

    The objective of this study was to assess factors affecting lung function among 685 workers in the rubberwood (Hevea brasiliensis) furniture industry in the Chonburi and Rayung provinces of eastern Thailand. Study data were gathered using questionnaires, by sampling wood dust, and by spirometry. The mean wood dust exposure level in the factories was 4.08 mg/m3 (SD = 1.42, range: 1.15-11.17 mg/m3). The mean overall percent of predicted forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC values were 84 % (SD = 13.41), 86 % (SD = 14.40), and 99% (SD = 10.42), respectively. Significant negative correlations were found between mean dust exposure levels and FVC (p = 0.0008), and FEV1/FVC% (p lung function and wood dust levels among wood workers suggests that rubberwood dust exposure negatively affects lung function.

    The overall mortality and the incidence of cancer have been studied among male employees at a plant producing calcium carbide. The cohort was defined as all men employed at the plant for at least 18 months in the period 1953 to 1970 and was classified according to 10 occupational categories. The 790 men have been observed from 1953 to 1983 and the incidence of cancer in the cohort has been compared with national incidence rates. A significant excess of colonic cancer (standardised incidence ratio, SIR = 2.09) and of prostatic cancer (SIR = 1.78) was found, and also a slight excess of lung cancer among furnace and maintenance workers (SIR = 1.56). The possible exposure of the workers to polycyclic aromatic hydrocarbons, asbestos, and cadmium is discussed.

    Recently, the use of ortho-phthalaldehyde (OPA) has been increasing as an alternative to glutaraldehyde for endoscope disinfection. To better understand OPA exposure and its health effects among disinfection workers, we conducted environmental monitoring and administered a questionnaire in 17 endoscope disinfection rooms. There were 9 manual disinfection rooms using immersion vats for scope disinfection and 8 automatic rooms using automatic washers. OPA exposure concentration during the disinfection process of scope was significantly higher in the manual group (median: 1.43ppb, range: not detected (ND-5.37ppb) than in the automatic group (median: 0.35 ppb, range: ND-0.69 ppb). Similarly, during charging and discharging the antiseptic solution, OPA levels were significantly higher in the manual group (median: 2.58 ppb, range: 0.92-10.0 ppb) than in the automatic group (median: 0.46ppb, range: ND-1.35 ppb). Time-weighted averages of OPA exposure concentration during work shifts were 0.33 to 1.15 ppb (median 0.66 ppb) in the manual group and 0.13 to 1.28 ppb (median 0.33 ppb) in the automatic group, which suggests that manual workers are exposed to OPA at higher levels. Among 80 female disinfection workers who used only antiseptic solutions containing OPA, the incidence of disinfection-related complaints were 10% skin, 9% eye, and 16% respiratory symptoms. These findings suggest that it is desirable to introduce automatic washers to decrease OPA exposure levels among disinfection workers.

    Objectives To investigate cancer risk, particularly oesophageal cancer, among male upstream petroleum workers offshore potentially exposed to various carcinogenic agents. Methods Using the Norwegian Registry of Employers and Employees, 24 765 male offshore workers registered from 1981 to 2003 was compared with 283 002 male referents from the general working population matched by age and community of residence. The historical cohort was linked to the Cancer Registry of Norway and the Norwegian Cause of Death Registry. Results Male offshore workers had excess risk of oesophageal cancer (RR 2.6, 95% CI 1.4 to 4.8) compared with the reference population. Only the adenocarcinoma type had a significantly increased risk (RR 2.7, 95% CI 1.0 to 7.0), mainly because of an increased risk among upstream operators (RR 4.3, 95% CI 1.3 to 14.5). Upstream operators did not have significant excess of respiratory system or colon cancer or mortality from any other lifestyle-related diseases investigated. Conclusion We found a fourfold excess risk of oesophageal adenocarcinoma among male workers assumed to have had the most extensive contact with crude oil. Due to the small number of cases, and a lack of detailed data on occupational exposure and lifestyle factors associated with oesophageal adenocarcinoma, the results must be interpreted with caution. Nevertheless, given the low risk of lifestyle-related cancers and causes of death in this working group, the results add to the observations in other low-powered studies on oesophageal cancer, further suggesting that factors related to the petroleum stream or carcinogenic agents used in the production process might be associated with risk of oesophageal adenocarcinoma.

    The 2008 Legal Arizona Workers Act (LAWA) requires all public and private employers to authenticate the legal status of their workers using the federal employment verification system known as E-Verify. With LAWA, Arizona became the first state to have a universal mandate for employment verification. While LAWA targets unauthorized workers, most of whom are Latino immigrants, other groups could experience LAWA's effects, such as those who share households with undocumented workers. In addition, employers may seek to minimize their risk of LAWA penalties by not hiring those who appear to them as more likely to be unauthorized, such as naturalized Latino immigrants and US-born Latinos. Existing research has found a reduction in foreign-born Latino employment and population in response to LAWA. This paper asks a different question: have groups that are most likely to be affected by the law migrated to other states? We find a significant and sustained increase in the internal outmigration rate from Arizona of foreign-born, noncitizen Latinos - the group most likely to include the unauthorized - after the passage of LAWA. There was no significant LAWA internal migration response by foreign-born Latino citizens. US-born Latinos showed some signs of a LAWA-induced internal migration response after the law went into effect, but it is not sustained. The results indicate that local and state immigration policy can alter the settlement geography of the foreign born. This leads us to speculate about how immigrant settlement may adjust in the coming years to the intersecting geographies of post-recession economic opportunity and tiered immigration policies.

    Full Text Available Objective: To assess the prevalence of pain syndromes and theirrelation with stress in healthcare workers at primary healthcareunits. Methods: A total of 540 workers of 10 primary healthcareunits were assessed in partnership with the Hospital Israelita AlbertEinstein (HIAE, in São Paulo, in 2005, through the Prevalence of PainSyndromes in the General Population Survey and the Lipp’s StressSymptom Inventory for Adults. Statistical analysis was carriedthrough univariate and multivariate analyses using accurate binarylogistic regression models adjusted for the following variables: stress,sex, dyslipidemia and hypertension. Ratios were compared usingFisher-Freeman-Halton test. Results: 86.93% were women, 54.63%of females were married, the majority worked at daytime and hadattended high school. General prevalence of pain was 54.26% (56.57%of women and 38.24% of men. Schooling was inversely proportionalto onset of pain. Health agents were twice more likely to presentpain than other professionals. Pain likelihood increased by 1.98%each year, and by 20.7% within 10 years. The groups with chronicpain presented statistical significance with stress (p < 0.001.There was no statistical difference in use of medications, number ofphysiotherapy sessions and lost work days in the groups with chronicpain when compared with the group with acute pain. Both chronicand acute pain groups were statistically significant in all variableswhen compared with the group with no pain. Stress, dyslipidemiaand arterial hypertension were positively associated with pain.Employees with stress presented a 4.19-fold higher likelihood ofpresenting pain as compared to those with no stress. Conclusion:The prevalence of pain syndromes among primary healthcare unitsworkers was 54.63%, and it was influenced by schooling and stresslevels. Most workers affected were female. Preventive measuresmust be established for healthcare workers.

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

    Asphalt has a highly complex structure and it contains several organic compounds including polycyclic aromatic hydrocarbons and heterocyclic compounds. In this study, comet assay was used to detect the DNA damage in blood lymphocytes of 30 workers exposed to asphalt fumes and 30 nonexposed controls. This is the first report on Turkish asphalt workers' investigated DNA damage using the alkaline single cell gel electrophoresis (SCGE). The DNA damage was evaluated by the percentage of DNA in the comet tail (% tail DNA) for each cell. According to our results, workers exposed to asphalt fumes had higher DNA damage than the control group (p asphalt fumes caused a significant increase in DNA damage and the comet assay is a suitable method for determining DNA damage in asphalt workers.

    This study aimed to estimate the prevalence of posttraumatic stress disorder (PTSD) and to identify associated risk factors among migrant workers 4 years after the 2008 snowstorm in China. A cross-sectional survey of 528 respondents was conducted to collect data in Changsha, the capital of Hunan Province. A multistage cluster sampling method was applied in selecting subjects from migrant workers' gathering areas. Association between the independent variables and PTSD was analyzed using logistic regression analysis. The prevalence of PTSD was 17.42% among migrant workers in Changsha. Being male, being older than 35 years, being an electrician, having dependent children, suffering property damage, being without medical insurance, and having low social support were risk factors significantly related to the development of PTSD. Effective and sustainable mental health services should be directed particularly to the migrant workers, who are among the groups most vulnerable to the direct impact of snowstorms.

    Several halogenated hydrocarbons are suspected of causing adverse reproductive effects. Because of such concerns, the Oil, Chemical, and Atomic Workers International Union surveyed the reproductive histories of two groups of workers. One group worked at plants engaged in the production or use of halogenated hydrocarbons (exposed) whereas the others had no such opportunity for exposure (nonexposed). Although a low response rate precludes firm conclusions, the 1,280 completed questionnaires provide useful data for generating hypotheses in this developing field of interest. A history of diagnosed cancer was reported more frequently among exposed workers. The infant mortality rate was also significantly elevated among the offspring of exposed workers. No risk gradient was observed for episodes of infertility, fetal loss, congenital defects, or low-birthweight offspring. Concerns with nonresponse, exposure characterization, possible confounding factors, and limited statistical power are addressed. The results provide further suggestions which help to direct studies of occupational reproductive risks.

    2017-01-01

    Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health. PMID:28146056

    The aim of our work was to study the physical symptoms of upper- and lower-level white-collar workers using a questionnaire. The study was cross-sectional with a questionnaire posted to 15 000 working-age persons. The responses (6121) included 970 upper- and 1150 lower-level white-collar workers. In the upper- and lower-level white-collar worker groups, 45.7 and 56.0%, respectively, had experienced pain, numbness and aches in the neck either pretty often or more frequently. When comparing daily computer users and nonusers, there were significant differences in pain, numbness and aches in the neck or in the shoulders. In addition, age and gender influenced some physical symptoms. In the future, it is essential to take into account that working with computers can be especially associated with physical symptoms in the neck and in the shoulders when workers use computers daily.

    Full Text Available This paper studies the effects of fixed-term contracts on workers. Specifically, the paper analyzes their impact on wages and on satisfaction levels. Regulations governing fixed-term and indefinite contracts in Colombia and the main labor reforms related to these two types of contract are analyzed. Women, young and low-educated workers, who work in small firms, in the private sector and in construction or manufacturing are most likely to have fixed-term contracts. In terms of wages, we found a significant raw and adjusted wage gap against workers with fixed-term contracts. Finally, we found, as expected, evidence that fixed-term contracts reduce the level of worker satisfaction.

    The ability to ensure adequate numbers of medical staff represents a crucial part of the medical response to any disaster. However, healthcare worker absenteeism during disasters, especially in the event of an attack of biological terrorism or an epidemic such as pandemic influenza, is a serious concern. Though a significant rate of absenteeism is often included as a baseline assumption in emergency planning, published reports on strategies to minimize absenteeism are comparatively few. This report documents interviews with managers and emergency response planners at hospitals and public health agencies and reviews existing survey data on healthcare worker absenteeism and studies of disasters to glean lessons about the needs of healthcare workers during those disasters. Based on this research, expected rates of absenteeism and individual determinants of absenteeism are presented along with recommendations of steps that hospitals, emergency medical services departments, public health organizations, and government agencies can take to meet the needs of healthcare workers and minimize absenteeism during a biological event.

    Foodborne disease is a significant problem worldwide. Research exploring sources of outbreaks indicates a pronounced role for food workers' improper health and hygiene practice. To investigate food workers' perceptions of factors that impact proper food safety practice. Interviews with food service workers in Baltimore, MD, USA discussing food safety practices and factors that impact implementation in the workplace. A social ecological model organizes multiple levels of influence on health and hygiene behavior. Issues raised by interviewees include factors across the five levels of the social ecological model, and confirm findings from previous work. Interviews also reveal many factors not highlighted in prior work, including issues with food service policies and procedures, working conditions (e.g., pay and benefits), community resources, and state and federal policies. Food safety interventions should adopt an ecological orientation that accounts for factors at multiple levels, including workers' social and structural context, that impact food safety practice.

    The stage in preimaginal ontogeny at which the sexes can first be distinguished has important implications for queen-worker conflict in social insects. If workers are unable to sex larvae at an early instar, their opportunity to control colony reproductive strategies may be limited. In addition, by concealing the sex of her sons for some portion of development, the queen could protect them from the workers' attempts to substitute their own sons or to skew the numerical sex ratio. In a series of choice experiments, workers of the carpenter ant, Camponotus floridanus, failed to discriminate the sex of several stages of larvae but did retrieve female pupae significantly more rapidly than male pupae. Our results suggest that in this species, sex may not become detectable until pupation, which is consistent with sexual deception as an aspect of queen control.

    With the gradual acceleration of urbanization speed and continuous improvements of agricultural productivity, the number of migrant workers is increasing. The living conditions of this group in cities determine the quality of urbanization in China, and are of great and far-reaching significance to Chinese construction of comprehensive well-off society. This study took the migrant workers in Heilongjiang Province as the research object, and took the representative new-generation migrant workers as the respondent to have a comprehensive analysis of the employment status. The study focused on these aspects, such as nature information, employment selection, employment quality, and social security, etc. Finally, it provided valuable ideas and methods on the reasonable solutions of the employment problems of the migrant workers to better increase farmers' income and improve their living qualities.

    Purpose To investigate the association between selfreported exposure to disturbing noise and risk of long-term sickness absence (LTSA) for more than two consecutive weeks among office workers. Methods LTSA was measured using register data that were linked to survey data from 2,883 office workers...... aged 18–59 who were surveyed in 2005 on exposure to disturbing noise. The risk of LTSA was investigated using Cox proportional hazards model. Results Of the study population, 4.4 % had LTSA in the 1-year follow-up period. Compared to office workers who were ‘rarely or never’ exposed to disturbing noise...... at work, office workers who reported being ‘frequently’ exposed to disturbing noise had a significantly increased estimated risk of LTSA when adjusting for age, gender, smoking status, and managerial position (HR = 1.90; 95 % CI, 1.12–3.22). After additional adjustment for psychosocial work conditions...

    Full Text Available According to several researchers, workers involvement into the implementation of a quality system in a firm is a key of its success. Since training can improve workers involvement during the implementation of a quality system in a firm, we try in this paper to evaluate quantitatively in the case of Montenegro, the impact of training of workers' involvement. Using an original data set about two leading firms from Montenegro, we show that the coefficient associated with the training variable is on average about -1.44 and is significant at a level of 1%. That is workers who are not trained during the ISO 9001 implementation are strongly less involved into the quality management process of their firms.

    Full Text Available Green jobs, in environmental and eco-friendly sectors, are defined as jobs where decent work conditions are presented. The green jobs, significantly increasing all over the world, support the protection of natural resources and also provide high quality work life for workers. The goal of this research is to improve the job satisfaction scale for green job workers by using the Structural Equation Model with model development strategy. Within this research SPSS 21 has been used for internal consistency rate and exploratory factor analysis and smartPLS 2.0 has been used for Structural Equation Model. Analysis results show that contingent reward, supervision, co-workers and communication effect job satisfaction of green job workers.
