Pinning of fermionic occupation numbers.
Schilling, Christian; Gross, David; Christandl, Matthias
2013-01-25
The Pauli exclusion principle is a constraint on the natural occupation numbers of fermionic states. It has been suspected since at least the 1970s, and only proved very recently, that there is a multitude of further constraints on these numbers, generalizing the Pauli principle. Here, we provide the first analytic analysis of the physical relevance of these constraints. We compute the natural occupation numbers for the ground states of a family of interacting fermions in a harmonic potential. Intriguingly, we find that the occupation numbers are almost, but not exactly, pinned to the boundary of the allowed region (quasipinned). The result suggests that the physics behind the phenomenon is richer than previously appreciated. In particular, it shows that for some models, the generalized Pauli constraints play a role for the ground state, even though they do not limit the ground-state energy. Our findings suggest a generalization of the Hartree-Fock approximation.

Natural occupation numbers: when do they vanish?
Giesbertz, K J H; van Leeuwen, R
2013-09-14
The non-vanishing of the natural orbital (NO) occupation numbers of the one-particle density matrix of many-body systems has important consequences for the existence of a density matrix-potential mapping for nonlocal potentials in reduced density matrix functional theory and for the validity of the extended Koopmans' theorem. On the basis of Weyl's theorem we give a connection between the differentiability properties of the ground state wavefunction and the rate at which the natural occupations approach zero when ordered as a descending series. We show, in particular, that the presence of a Coulomb cusp in the wavefunction leads, in general, to a power law decay of the natural occupations, whereas infinitely differentiable wavefunctions typically have natural occupations that decay exponentially. We analyze for a number of explicit examples of two-particle systems that in case the wavefunction is non-analytic at its spatial diagonal (for instance, due to the presence of a Coulomb cusp) the natural orbital occupations are non-vanishing. We further derive a more general criterium for the non-vanishing of NO occupations for two-particle wavefunctions with a certain separability structure. On the basis of this criterium we show that for a two-particle system of harmonically confined electrons with a Coulombic interaction (the so-called Hookium) the natural orbital occupations never vanish.

Urban economies are composed of diverse activities, embodied in labor occupations, which depend on one another to produce goods and services. Yet little is known about how the nature and intensity of these interdependences change as cities increase in population size and economic complexity. Understanding the relationship between occupational interdependencies and the number of occupations defining an urban economy is relevant because interdependence within a networked system has implications for system resilience and for how easily can the structure of the network be modified. Here, we represent the interdependencies among occupations in a city as a non-spatial information network, where the strengths of interdependence between pairs of occupations determine the strengths of the links in the network. Using those quantified link strengths we calculate a single metric of interdependence-or connectedness-which is equivalent to the density of a city's weighted occupational network. We then examine urban systems in six industrialized countries, analyzing how the density of urban occupational networks changes with network size, measured as the number of unique occupations present in an urban workforce. We find that in all six countries, density, or economic interdependence, increases superlinearly with the number of distinct occupations. Because connections among occupations represent flows of information, we provide evidence that connectivity scales superlinearly with network size in information networks.

Mass, surface area and number metrics in diesel occupational exposure assessment.
Ramachandran, Gurumurthy; Paulsen, Dwane; Watts, Winthrop; Kittelson, David
2005-07-01
While diesel aerosol exposure assessment has traditionally been based on the mass concentration metric, recent studies have suggested that particle number and surface area concentrations may be more health-relevant. In this study, we evaluated the exposures of three occupational groups-bus drivers, parking garage attendants, and bus mechanics-using the mass concentration of elemental carbon (EC) as well as surface area and number concentrations. These occupational groups are exposed to mixtures of diesel and gasoline exhaust on a regular basis in various ratios. The three groups had significantly different exposures to workshift TWA EC with the highest levels observed in the bus garage mechanics and the lowest levels in the parking ramp booth attendants. In terms of surface area, parking ramp attendants had significantly greater exposures than bus garage mechanics, who in turn had significantly greater exposures than bus drivers. In terms of number concentrations, the exposures of garage mechanics exceeded those of ramp booth attendants by a factor of 5-6. Depending on the exposure metric chosen, the three occupational groups had quite different exposure rankings. This illustrates the importance of the choice of exposure metric in epidemiological studies. If these three occupational groups were part of an epidemiological study, depending on the metric used, they may or may not be part of the same similarly exposed group (SEG). The exposure rankings (e.g., low, medium, or high) of the three groups also changes with the metric used. If the incorrect metric is used, significant misclassification errors may occur.

Natural occupation numbers in two-electron quantum rings.
Tognetti, Vincent; Loos, Pierre-François
2016-02-07
Natural orbitals (NOs) are central constituents for evaluating correlation energies through efficient approximations. Here, we report the closed-form expression of the NOs of two-electron quantum rings, which are prototypical finite-extension systems and new starting points for the development of exchange-correlation functionals in density functional theory. We also show that the natural occupation numbers for these two-electron paradigms are in general non-vanishing and follow the same power law decay as atomic and molecular two-electron systems.

Infinite occupation number basis of bosons: Solving a numerical challenge
NASA Astrophysics Data System (ADS)
Geißler, Andreas; Hofstetter, Walter
2017-06-01
In any bosonic lattice system, which is not dominated by local interactions and thus "frozen" in a Mott-type state, numerical methods have to cope with the infinite size of the corresponding Hilbert space even for finite lattice sizes. While it is common practice to restrict the local occupation number basis to Nc lowest occupied states, the presence of a finite condensate fraction requires the complete number basis for an exact representation of the many-body ground state. In this work we present a truncation scheme to account for contributions from higher number states. By simply adding a single coherent-tail state to this common truncation, we demonstrate increased numerical accuracy and the possible increase in numerical efficiency of this method for the Gutzwiller variational wave function and within dynamical mean-field theory.

Although occupational accidents and work-related diseases have been of interest for a long time, due to lack of proper recording and notification systems the official numbers of occupational accidents and work-related diseases are missing for many countries. Presently, the demand for effectiveness and an interest in the economic aspects of accidents have increased prevention activities at company and country levels. Occupational accident data of selected countries and of World Health Organization regional divisions together with the global burden of disease were used in estimating global occupational accidents and fatal work-related diseases. The trend of global occupational accidents and work-related diseases is presented at region and country levels. The years 1998, 2001, and 2003 are compared in the case of occupational accidents and the years 2000 and 2002 in the case of work-related diseases. The total number of occupational accidents and fatal work-related diseases has increased, but the fatality rates per 100,000 workers have decreased. There were almost 360,000 fatal occupational accidents in 2003 and almost 2 million fatal work-related diseases in 2002. Every day more than 960,000 workers get hurt because of accidents. Each day 5,330 people die because of work-related diseases. Information on occupational accidents and work-related diseases is needed so that countries may understand better the importance of occupational health and safety at country and company level. Especially companies in developing countries are not familiar with occupational safety and health. Statistical data is essential for accident prevention; it is a starting point for the safety work.

Occupational cancer in Britain. Preventing occupational cancer.
Chen, Yiqun; Osman, John
2012-06-19
Although only a relatively small proportion of cancer is attributable to occupational exposure to carcinogenic agents, the estimated number of deaths due to occupational cancer is high when compared to other deaths due to work-related ill health and injury. However, risk from occupational exposure to carcinogens can be minimised through proportionate but effective risk management. The Health and Safety Executive (HSE) is the regulator of workplace health and safety in Great Britain. As part of its aim to reduce ill health arising from failures to control properly exposure to hazards at work, HSE commissioned the research presented elsewhere in this supplement to enable it to identify priorities for preventing occupational cancer. The research has shown that occupational cancer remains a key health issue and that low-level exposure of a large number of workers to carcinogens is important. The finding that a small number of carcinogens have been responsible for the majority of the burden of occupational cancer provides key evidence in the development of priorities for significant reduction of occupational cancer. Although the research presented in this supplement reflects the consequences of past exposures to carcinogens, occupational cancer remains a problem. The potential for exposure to the agents considered in this research is still present in the workplace and the findings are relevant to prevention of future disease. In this article, the principle approaches for risk reduction are described. It provides supporting information on some of the initiatives already being undertaken, or those being put in place, to reduce occupational cancer in Great Britain. The need also for systematic collection of exposure information and the importance of raising awareness and changing behaviours are discussed.

Reliable knowledge of the status and trend of carnivore populations is critical to their conservation and management. Methods for monitoring carnivores, however, are challenging to conduct across large spatial scales. In the Northern Rocky Mountains, wildlife managers need a time- and cost-efficient method for monitoring gray wolf (Canis lupus) populations. Montana Fish, Wildlife and Parks (MFWP) conducts annual telephone surveys of >50,000 deer and elk hunters. We explored how survey data on hunters' sightings of wolves could be used to estimate the occupancy and distribution of wolf packs and predict their abundance in Montana for 2007–2009. We assessed model utility by comparing our predictions to MFWP minimum known number of wolf packs. We minimized false positive detections by identifying a patch as occupied if 2–25 wolves were detected by ≥3 hunters. Overall, estimates of the occupancy and distribution of wolf packs were generally consistent with known distributions. Our predictions of the total area occupied increased from 2007 to 2009 and predicted numbers of wolf packs were approximately 1.34–1.46 times the MFWP minimum counts for each year of the survey. Our results indicate that multi-season occupancy models based on public sightings can be used to monitor populations and changes in the spatial distribution of territorial carnivores across large areas where alternative methods may be limited by personnel, time, accessibility, and budget constraints.

Symmetry breaking in occupation number based slave-particle methods
NASA Astrophysics Data System (ADS)
Georgescu, Alexandru B.; Ismail-Beigi, Sohrab
2017-10-01
We describe a theoretical approach to finding spontaneously symmetry-broken electronic phases due to strong electronic interactions when using recently developed slave-particle (slave-boson) approaches based on occupation numbers. We describe why, to date, spontaneous symmetry breaking has proven difficult to achieve in such approaches. We then provide a total energy based approach for introducing auxiliary symmetry-breaking fields into the solution of the slave-particle problem that leads to lowered total energies for symmetry-broken phases. We point out that not all slave-particle approaches yield energy lowering: the slave-particle model being used must explicitly describe the degrees of freedom that break symmetry. Finally, our total energy approach permits us to greatly simplify the formalism used to achieve a self-consistent solution between spinon and slave modes while increasing the numerical stability and greatly speeding up the calculations.

Few data are available about the prevalence of occupational exposures to agents which can cause occupational asthma or aggravate preexisting asthma (asthmogens). Using potential occupational exposure data from the National Occupational Exposure Survey (NOES) of 1980-1983, we investigated the number of asthmogen exposures, asthmogen-exposure(s) per production worker, and unprotected occupational asthmogen exposures in different industries and occupations. Data for the entire United States were used to generate estimates of occupational exposure at two selected state and local levels. It was estimated that 7,864,000 workers in the surveyed industries were potentially exposed to one or more occupational asthmogen(s) in the United States. The average number of observed potential exposures per asthmogen-exposed worker was 4.4, and varied from 11.9, in the Water Transportation industry, to 1.2 in Local and Suburban transportation. The largest number of observed potential exposures was recorded in the Apparel and Other Finished Products (garment) industry. This work and further analyses using this approach are expected to contribute to a better understanding of the epidemiology of occupational asthma, and to serve as a guide to target future occupational asthma surveillance efforts.

We study statistical properties of N noninteracting identical bosons or fermions in the canonical ensemble. We derive several general representations for the p -point correlation function of occupation numbers n1⋯np ¯. We demonstrate that it can be expressed as a ratio of two p ×p determinants involving the (canonical) mean occupations n1¯, ..., np¯, which can themselves be conveniently expressed in terms of the k -body partition functions (with k ≤N ). We draw some connection with the theory of symmetric functions and obtain an expression of the correlation function in terms of Schur functions. Our findings are illustrated by revisiting the problem of Bose-Einstein condensation in a one-dimensional harmonic trap, for which we get analytical results. We get the moments of the occupation numbers and the correlation between ground-state and excited-state occupancies. In the temperature regime dominated by quantum correlations, the distribution of the ground-state occupancy is shown to be a truncated Gumbel law. The Gumbel law, describing extreme-value statistics, is obtained when the temperature is much smaller than the Bose-Einstein temperature.

The number of animals required to represent the collective characteristics of a group remains a concern in animal movement monitoring with GPS. Monitoring a subset of animals from a group instead of all animals can reduce costs and labor; however, incomplete data may cause information losses and inaccuracy in subsequent data analyses. In cattle studies, little work has been conducted to determine the number of cattle within a group needed to be instrumented considering subsequent analyses. Two different groups of cattle (a mixed group of 24 beef cows and heifers, and another group of 8 beef cows) were monitored with GPS collars at 4 min intervals on intensively managed pastures and corn residue fields in 2011. The effects of subset group size on cattle movement characterization and spatial occupancy analysis were evaluated by comparing the results between subset groups and the entire group for a variety of summarization parameters. As expected, more animals yield better results for all parameters. Results show the average group travel speed and daily travel distances are overestimated as subset group size decreases, while the average group radius is underestimated. Accuracy of group centroid locations and group radii are improved linearly as subset group size increases. A kernel density estimation was performed to quantify the spatial occupancy by cattle via GPS location data. Results show animals among the group had high similarity of spatial occupancy. Decisions regarding choosing an appropriate subset group size for monitoring depend on the specific use of data for subsequent analysis: a small subset group may be adequate for identifying areas visited by cattle; larger subset group size (e.g. subset group containing more than 75% of animals) is recommended to achieve better accuracy of group movement characteristics and spatial occupancy for the use of correlating cattle locations with other environmental factors.

1988-09-01
The authors examined the relationship between perceived occupational stress and the prevalence of a number of psychologic and physical ailments in a sample of professional symphony orchestra musicians and related musicians' self-reports of stress to demographic and occupational characteristics. Results of a survey of 2,212 musicians from 47 symphony orchestras revealed a significant relationship between perceived occupational stress and prevalence of a number of psychologic as well as physical medical problems. Age and occupational factors, such as the orchestra in which the musician plays, the instrument played, and status as a soloist, were also found to be significant correlates of perceived stress.

Occupational skin diseases in Korea.
Ahn, Yeon-Soon; Kim, Min-Gi
2010-12-01
Skin disease is the most common occupational disease, but the reported number is small in Korea due to a difficulty of detection and diagnosis in time. We described various official statistics and data from occupational skin disease surveillance system, epidemiological surveys and cases published in scientific journals. Until 1981, 2,222 cases of occupational skin disease were reported by Korean employee's regular medical check-up, accounting for 4.9% of the total occupational diseases. There was no subsequent official statistics to figure out occupational skin diseases till 1998. From 1999, the Korea Occupational Safety and Health Agency (KOSHA) published the number of occupational skin diseases through the statistics of Cause Investigation for Industrial Accidents. A total of 301 cases were reported from 1999 to 2007. Recent one study showed the figures of compensated occupational skin diseases. Many of them belonged to daily-paid workers in the public service, especially forestry workers. Also, it described the interesting cases such as vitiligo and trichloroethylene-induced Stevens-Johnson Syndrome. Skin diseases are still important though the number of cases has decreased, and therefore it is recommended to grasp the status of occupational skin diseases through continuous surveillance system and to make policy protecting high-risk group.

To investigate the current status of occupational health and related countermeasures in Guangzhou, China. Related data were collected from occupational poisoning accident investigation, diagnosis and identification of occupational diseases, and the occupational disease hazard reporting system, and the statistical data of occupational health in Guangzhou were analyzed retrospectively. The number of enterprises reporting for occupational disease hazards in Guangzhou was 20 890, and the total number of workers was 1 457 583. The number of workers exposed to occupational hazards was 284 233, and the cumulative number of workers with occupational diseases was 1 502. There were many risk factors for occupational diseases in enterprises, and there were a large number of workers with occupational diseases, as well as newly diagnosed cases. From 2001 to 2014, the total number of cases of occupational diseases was 958. The situation for the prevention and control of occupational diseases is grim in Guangzhou. Occupational health supervision and law enforcement should be enhanced, the three-level supervision system should be established and perfected, and the occupational health supervision system with a combination of "prevention, treatment, and protection" should be established and promoted, so as to gradually establish a technical service support system for occupational health.

A bibliometric analysis of occupational therapy publications.
Brown, Ted; Gutman, Sharon A; Ho, Yuh-Shan; Fong, Kenneth N K
2018-01-01
Bibliometrics involves the statistical analysis of the publications in a specific discipline or subject area. A bibliometric analysis of the occupational therapy refereed literature is needed. A bibliometric analysis was completed of the occupational therapy literature from 1991-2014, indexed in the Science Citation Index-Expanded or the Social Sciences Citation Index. Publications were searched by title, abstract, keywords, and KeyWords Plus. Total number of article citations, citations per journal, and contributions per country, individual authors, and institution were calculated. 5,315 occupational therapy articles were published in 821 journals. It appears that there is a citation window of an approximate 10-year period between the time of publication and the peak number of citations an article receives. The top three most highly cited articles were published in Developmental Medicine and Child Neurology, JAMA, and Lancet. AJOT, BJOT and AOTJ published the largest number of occupational therapy articles with the United States, Australia, and Canada producing the highest number of publications. McMaster University, the University of Queensland, and the University of Toronto were the institutions that published the largest number of occupational therapy journal articles. The occupational therapy literature is growing and the frequency of article citation is increasing.

The terms occupation and activity over the history of official occupational therapy publications.
Bauerschmidt, Bree; Nelson, David L
2011-01-01
The history of articles in the American Journal of Occupational Therapy and its predecessors reflects trends and changes in professional terminology and the thoughts underlying that terminology. In this study, we investigate use of occupation, activity, and related terms across 9 decades of occupational therapy literature from the 1920s to the 2000s. The literature for 3 years of each of the 9 decades was scanned electronically. A random numbers table was used to equalize the number of words across decades, and a computer search function was used to determine each term's frequency of use for each decade. Results indicated that the term occupation was widely used in the 1920s but then declined until the 1980s. With a rapid increase in use in the 2000s, the term occupation actually appeared more often than it did in the 1920s. The term activity appeared infrequently in the 1920s but gained popularity from the 1930s to the 1960s. From the 1970s to the 1990s, the use of both terms was quite low. This study shows that basic occupational therapy terminology has fluctuated dramatically over time. Given the essential link between terminology and theory, these changes arguably reflect authors' and editors' changing viewpoints on the profession's fundamental nature.

Image Processing Occupancy Sensor
DOE Office of Scientific and Technical Information (OSTI.GOV)
The Image Processing Occupancy Sensor, or IPOS, is a novel sensor technology developed at the National Renewable Energy Laboratory (NREL). The sensor is based on low-cost embedded microprocessors widely used by the smartphone industry and leverages mature open-source computer vision software libraries. Compared to traditional passive infrared and ultrasonic-based motion sensors currently used for occupancy detection, IPOS has shown the potential for improved accuracy and a richer set of feedback signals for occupant-optimized lighting, daylighting, temperature setback, ventilation control, and other occupancy and location-based uses. Unlike traditional passive infrared (PIR) or ultrasonic occupancy sensors, which infer occupancy based only onmore » motion, IPOS uses digital image-based analysis to detect and classify various aspects of occupancy, including the presence of occupants regardless of motion, their number, location, and activity levels of occupants, as well as the illuminance properties of the monitored space. The IPOS software leverages the recent availability of low-cost embedded computing platforms, computer vision software libraries, and camera elements.« less

The explosion of the Deepwater Horizon drilling platform created the largest marine oil spill in U.S. history. As part of the Natural Resource Damage Assessment process, we applied an innovative modeling approach to obtain upper estimates for occupancy and for number of manatees in areas potentially affected by the oil spill. Our data consisted of aerial survey counts in waters of the Florida Panhandle, Alabama and Mississippi. Our method, which uses a Bayesian approach, allows for the propagation of uncertainty associated with estimates from empirical data and from the published literature. We illustrate that it is possible to derive estimates of occupancy rate and upper estimates of the number of manatees present at the time of sampling, even when no manatees were observed in our sampled plots during surveys. We estimated that fewer than 2.4% of potentially affected manatee habitat in our Florida study area may have been occupied by manatees. The upper estimate for the number of manatees present in potentially impacted areas (within our study area) was estimated with our model to be 74 (95%CI 46 to 107). This upper estimate for the number of manatees was conditioned on the upper 95%CI value of the occupancy rate. In other words, based on our estimates, it is highly probable that there were 107 or fewer manatees in our study area during the time of our surveys. Because our analyses apply to habitats considered likely manatee habitats, our inference is restricted to these sites and to the time frame of our surveys. Given that manatees may be hard to see during aerial surveys, it was important to account for imperfect detection. The approach that we described can be useful for determining the best allocation of resources for monitoring and conservation. PMID:24670971

Brazil is a recently industrialised country with marked contrasts in social and economic development. The availability of public/private services in its different regions also varies. Health indicators follow these trends. Occupational health is a vast new field, as in other developing countries. Occupational medicine is a required subject in graduation courses for physicians. Specialisation courses for university graduated professionals have more than 700 hours of lectures and train occupational health physicians, safety engineers and nursing staff. At the technical level, there are courses with up to 1300 hours for the training of safety inspectors. Until 1986 about 19,000 occupational health physicians, 18,000 safety engineers and 51,000 safety inspectors had been officially registered. Although in its infancy, postgraduation has attracted professionals at university level, through residence programmes as well as masters and doctors degrees, whereby at least a hundred good-quality research studies have been produced so far. Occupational health activities are controlled by law. Undertakings with higher risks and larger number of employees are required to hire specialised technical staff. In 1995 the Ministry of Labour demanded programmes of medical control of occupational health (PCMSO) for every worker as well as a programme of prevention of environmental hazards (PPRA). This was considered as a positive measure for the improvement of working conditions and health at work. Physicians specialising in occupational medicine are the professionals more often hired by the enterprises. Reference centres (CRSTs) for workers' health are connected to the State or City Health Secretariat primary health care units. They exist in more populated areas and are accepted by workers as the best way to accomplish the diagnosis of occupational diseases. There is important participation by the trade unions in the management of these reference centres. For 30 years now employers

Viral hepatitis as an occupational disease in Poland.
Bilski, Bartosz
2011-07-01
In medical terms, occupational diseases are defined as health disorders specifically associated with the working environment of people and their occupational activity. From the medical and legal perspectives, the vast majority of European countries consider particular diseases to be of occupational origin if they are mentioned in the current list of occupational diseases and caused by exposure to factors in the working environment that are harmful to health. The aim of this study was to analyze the occurrence of cases of viral hepatitis certified as an occupational disease in Poland during 1979-2009. This article presents the medical, economic, and legal aspects of the epidemiology of hepatitis as an occupational disease in Poland. Publically available statistical data on certified occupational diseases in Poland and data contained in individual "occupational disease diagnosis cards" (based on data used in Poland statistical form), regarding certified cases of hepatitis among health care professionals, which were collected by the Department of Occupational Hygiene of the Polish Public Health Service, were analyzed in this study. In Poland, the highest number of cases of hepatitis certified as an occupational disease was observed in 1987. A gradual reduction in the number of cases of hepatitis as an occupational disease has been noted since then. Currently, hepatitis C as an occupational disease is certified more frequently than hepatitis B. In Poland, the number of women with hepatitis certified as an occupational disease is higher than that of men. However, among health care professionals, particularly nurses, this difference is insignificant because women outnumber the men. The existence of such a situation is due to the significant quantitative predominance of women over men among medical personnel, especially among nurses. Immunization of health care professionals against the hepatitis B virus (HBV), introduced in Poland in 1988, was an important factor

Fatalities from occupational diseases in Connecticut.
Morse, T; Storey, E
1999-08-01
Occupational diseases in Connecticut were identified using reports to the Workers' Compensation Commission, Connecticut OSHA, Vital Statistics, and the Tumor Registry. There were 93 identified fatalities from occupational disease in 1995, and 90 in 1994, approximately three times the number of traumatic occupational fatalities. Identified fatalities were predominantly from asbestos-related diseases, including mesothelioma and asbestosis. Most occupational diseases are not readily identifiable with current reporting mechanisms. Based on national estimates, these figures are considered to be an underestimate of the true burden of occupational disease. Increased awareness and reporting of occupational diseases is needed to properly identify and prevent these common conditions.

Entropy Production in Collisionless Systems. II. Arbitrary Phase-space Occupation Numbers
NASA Astrophysics Data System (ADS)
Barnes, Eric I.; Williams, Liliya L. R.
2012-04-01
We present an analysis of two thermodynamic techniques for determining equilibria of self-gravitating systems. One is the Lynden-Bell (LB) entropy maximization analysis that introduced violent relaxation. Since we do not use the Stirling approximation, which is invalid at small occupation numbers, our systems have finite mass, unlike LB's isothermal spheres. (Instead of Stirling, we utilize a very accurate smooth approximation for ln x!.) The second analysis extends entropy production extremization to self-gravitating systems, also without the use of the Stirling approximation. In addition to the LB statistical family characterized by the exclusion principle in phase space, and designed to treat collisionless systems, we also apply the two approaches to the Maxwell-Boltzmann (MB) families, which have no exclusion principle and hence represent collisional systems. We implicitly assume that all of the phase space is equally accessible. We derive entropy production expressions for both families and give the extremum conditions for entropy production. Surprisingly, our analysis indicates that extremizing entropy production rate results in systems that have maximum entropy, in both LB and MB statistics. In other words, both thermodynamic approaches lead to the same equilibrium structures.

Real-Time Occupancy Change Analyzer
DOE Office of Scientific and Technical Information (OSTI.GOV)

The Real-Time Occupancy Change Analyzer (ROCA) produces an occupancy grid map of an environment around the robot, scans the environment to generate a current obstacle map relative to a current robot position, and converts the current obstacle map to a current occupancy grid map. Changes in the occupancy grid can be reported in real time to support a number of tracking capabilities. The benefit of ROCA is that rather than only providing a vector to the detected change, it provides the actual x,y position of the change.

Occupational pressure-targeting organisational factors to ameliorate occupational dysfunction.
Loh, Siew Yim; Than, Winn; Quek, Kia Fatt
2011-12-01
Chronic pressure at work has debilitating impact on healthcare employers (e.g. reduced productivity, high costs, poor patient care) and on female healthcare employees (e.g. sickness, dysfunction). This paper highlights relationship at work as the key occupational source of work-stress which is organisational in nature. A cross-sectional study (n = 230) was conducted using the Pressure Management Inventory on several female dominated health professions within a large public hospital. Analysis of variance was used to show relationship between sources and outcome of pressure. Linear regressions were used to predict which sources of pressure (IV) was linked to the outcomes of occupational pressure (DV). The number one source of occupational pressure is relationships at work (i.e. with supervisors), and not workload. 'Relationship' is also the key predictor of several negative outcomes of pressure at work. Analysis of variance showed significant differences in two sources of pressures, i.e. Workload (P = 0.04) and Home-work balance (P = 0.03). This paper provides insights into the occupational pressure of women health professionals by highlighting the organisational sources of pressure and the implications for preventing occupational dysfunction secondary to stress at work.

Occupational injuries in Italy.
Baldasseroni, Alberto; Chellini, Elisabetta; Mantero, Silvia; Giovannetti, Lucia
2005-01-01
Data collected by the Italian Funds for Occupational Injuries and Diseases (INAIL) on incidence and mortality for occupational injuries in Italy during 1951-2001 are described with respect to the two main occupational sectors, Industry and Services, and Agriculture. Comparisons with other EU countries are included to place the current severe phenomenon in context. An ad hoc analysis aimed at verifying the completeness of the data on occupational fatal accidents collected by INAIL in Tuscany is reported: a linkage between the INAIL data and those registered by the Tuscan Regional Mortality Registry highlights that a number of working areas are not covered by INAIL, a problem whose solution would be useful for primary prevention.

Occupation and thyroid cancer.

2014-05-01
Numerous occupational and environmental exposures have been shown to disrupt thyroid hormones, but much less is known about their relationships with thyroid cancer. Here we review the epidemiology studies of occupations and occupational exposures and thyroid cancer incidence to provide insight into preventable risk factors for thyroid cancer. The published literature was searched using the Web of Knowledge database for all articles through August 2013 that had in their text 'occupation' 'job' 'employment' or 'work' and 'thyroid cancer'. After excluding 10 mortality studies and 4 studies with less than 5 exposed incident cases, we summarised the findings of 30 articles that examined thyroid cancer incidence in relation to occupations or occupational exposure. The studies were grouped by exposure/occupation category, study design and exposure assessment approach. Where available, gender-stratified results are reported. The most studied (19 of 30 studies) and the most consistent associations were observed for radiation-exposed workers and healthcare occupations. Suggestive, but inconsistent, associations were observed in studies of pesticide-exposed workers and agricultural occupations. Findings for other exposures and occupation groups were largely null. The majority of studies had few exposed cases and assessed exposure based on occupation or industry category, self-report, or generic (population-based) job exposure matrices. The suggestive, but inconsistent findings for many of the occupational exposures reviewed here indicate that more studies with larger numbers of cases and better exposure assessment are necessary, particularly for exposures known to disrupt thyroid homeostasis.

Occupational cancer in Britain

2012-01-01
To estimate the current occupational cancer burden due to past exposures in Britain, estimates of the number of exposed workers at different levels are required, as well as risk estimates of cancer due to the exposures. This paper describes the methods and results for estimating the historical exposures. All occupational carcinogens or exposure circumstances classified by the International Agency for Research on Cancer as definite or probable human carcinogens and potentially to be found in British workplaces over the past 20–40 years were included in this study. Estimates of the number of people exposed by industrial sector were based predominantly on two sources of data, the CARcinogen EXposure (CAREX) database and the UK Labour Force Survey. Where possible, multiple and overlapping exposures were taken into account. Dose–response risk estimates were generally not available in the epidemiological literature for the cancer–exposure pairs in this study, and none of the sources available for obtaining the numbers exposed provided data by different levels of exposure. Industrial sectors were therefore assigned using expert judgement to ‘higher'- and ‘lower'-exposure groups based on the similarity of exposure to the population in the key epidemiological studies from which risk estimates had been selected. Estimates of historical exposure prevalence were obtained for 41 carcinogens or occupational circumstances. These include exposures to chemicals and metals, combustion products, other mixtures or groups of chemicals, mineral and biological dusts, physical agents and work patterns, as well as occupations and industries that have been associated with increased risk of cancer, but for which the causative agents are unknown. There were more than half a million workers exposed to each of six carcinogens (radon, solar radiation, crystalline silica, mineral oils, non-arsenical insecticides and 2,3,7,8-tetrachlorodibenzo-p-dioxin); other agents to which a large

The overall incidence rates, numbers, and proportions of occupational skin diseases recorded in the Bureau of Labor Statistics Annual Survey of Occupational Injuries and Illnesses, from 1973 through 1984, were reviewed, and a detailed analysis of occupational skin diseases recorded in the 1984 Annual Survey was performed. Overall incidence rates and numbers of cases declined from 1973 through 1983, but increased slightly in 1984. The major industrial divisions of agriculture and manufacturing have consistently had the highest rates and numbers of cases, respectively; skin diseases have accounted for almost two thirds of all occupational illnesses within agriculture. In the 1984 Annual Survey, 11 industries were ranked in the "Top 15" for both incidence rates and numbers of cases, at the two-digit Standard Industrial Classification level. At the four-digit level for manufacturing, four industries were also ranked in the "Top 15" for both indexes. This analysis has identified industries toward which research efforts should be directed to characterize those occupational activities or exposures most responsible for these higher risks.

A direct method (D-Delta-MBPT(2)) to calculate second-order ionization potentials (IPs), electron affinities (EAs), and excitation energies is developed. The Delta-MBPT(2) method is defined as the correlated extension of the Delta-HF method. Energy differences are obtained by integrating the energy derivative with respect to occupation numbers over the appropriate parameter range. This is made possible by writing the second-order energy as a function of the occupation numbers. Relaxation effects are fully included at the SCF level. This is in contrast to linear response theory, which makes the D-Delta-MBPT(2) applicable not only to single excited but also higher excited states. We showmore » the relationship of the D-Delta-MBPT(2) method for IPs and EAs to a second-order approximation of the effective Fock-space coupled-cluster Hamiltonian and a second-order electron propagator method. We also discuss the connection between the D-Delta-MBPT(2) method for excitation energies and the CIS-MP2 method. Finally, as a proof of principle, we apply our method to calculate ionization potentials and excitation energies of some small molecules. For IPs, the Delta-MBPT(2) results compare well to the second-order solution of the Dyson equation. For excitation energies, the deviation from EOM-CCSD increases when correlation becomes more important. When using the numerical integration technique, we encounter difficulties that prevented us from reaching the Delta-MBPT(2) values. Most importantly, relaxation beyond the Hartree Fock level is significant and needs to be included in future research.« less

[News on occupational contact dermatitis].
Crépy, Marie-Noëlle; Bensefa-Colas, Lynda
2014-03-01
Contact dermatitis--irritant contact dermatitis, allergic contact dermatitis and protein contact dermatitis--are the most common occupational skin diseases, most often localized to the hands. Contact urticaria is rarer The main occupational irritants are wet work, detergents and disinfectants, cutting oils, and solvents. The main occupational allergens are rubber additives, metals (chromium, nickel, cobalt), plastics (epoxy resins, acrylic), biocides and plants. Diagnosis is based on clinical examination, medical history and allergy testing. For a number of irritating or sensitizing agents, irritant or allergic dermatitis can be notified as occupational diseases. The two main prevention measures are reducing skin contact with irritants and complete avoidance of skin contact with offending allergens.

This article is a discussion of occupational cancer in Italy. The introduction provides the necessary context of Italian industrialization and occupational health regulation. This is followed by a review of Italian epidemiologic studies of occupational cancer risks considered in terms of relative measures of risk and attributable risk of carcinogenic agents or exposure circumstances. We attempt to establish the number of workers exposed to carcinogens in Italy and the intensity of their exposures. Finally, the Italian system of compensation for occupational cancer is discussed. Several cohort and case-control studies have addressed the issue of occupational risks, mostly among male workers. The results of these studies suggest that the growing incidence of and mortality by mesothelioma is explained by the widespread and intense exposure to asbestos in some Italian industrial settings. A high attributable risk of lung tumors among male populations in industrial areas of northern Italy is explained by occupational exposures. However, insufficient data are available for clear definition of the extent and intensity of occupational exposure to carcinogenic substances. In Italy, we must prioritize and maximize resources in occupational cancer epidemiology and revitalize the role of national institutions. Recent legislation has established new regulations on the handling of carcinogenic substances in industrial settings, a new list of occupational diseases, and a national registry of mesothelioma linked to asbestos exposure. These legislative changes are expected to have positive effects. PMID:10350509

Occupational Psychiatric Disorders in Korea
Kang, Seong-Kyu
2010-01-01
We searched databases and used various online resources to identify and systematically review all articles on occupational psychiatric disorders among Korean workers published in English and Korean before 2009. Three kinds of occupational psychiatric disorders were studied: disorders related to job stress and mental illness, psychiatric symptoms emerging in victims of industrial injuries, and occupational psychiatric disorders compensated by Industrial Accident Compensation Insurance (IACI). Korea does not maintain official statistical records for occupational psychiatric disorders, but several studies have estimated the number of occupational psychiatric disorders using the Korea Workers' Compensation and Welfare Service (COMWEL, formerly KLWC) database. The major compensated occupational psychiatric disorders in Korea were "personality and behavioral disorders due to brain disease, damage, and dysfunction", "other mental disorders due to brain damage and dysfunction and to physical diseases", "reactions to severe stress and adjustment disorders", and "depressive episodes". The most common work-related psychiatric disorders, excluding accidents, were "neurotic, stress-related, and somatoform disorders" followed by "mood disorders". PMID:21258596

Occupational asthma is the most frequently diagnosed occupational lung disease reported to the SWORD (Surveillance of Work-related and Occupational Respiratory Disease) scheme. However, diagnosing occupational asthma is not straightforward, and establishing a link with work may be difficult. This study was undertaken to determine the differences between patients with occupational asthma and those with non-occupational asthma which might help in their diagnosis. Information was collected using a self-completed questionnaire. Questionnaires were distributed to 30 subjects aged 18-65 years at each of two clinics--one for patients with occupational asthma and one for those with cryptogenic and environmental asthma. Replies were received from 26 patients with occupational asthma (87%) and 29 patients with non-occupational asthma (97%). The age of onset was significantly higher for those with occupational asthma (42.6 vs 20.7 years). Significantly more subjects with occupational asthma reported improvement on holiday, whereas no significant difference was found in the numbers reporting worsening of symptoms on work days. Those with occupational asthma were less likely to report seasonal variation in symptoms, exacerbation by allergies, pets and stress, or a family history of asthma. Subjects with occupational asthma were more likely to become unemployed (50% vs 3%). Recognition of some of these features in a patient's history may help in the difficult task of differentiating occupational from non-occupational asthma, potentially avoiding the need for exhaustive investigations in some patients. The high prevalence of holiday improvement among subjects with non-occupational asthma suggested that domestic or environmental allergies arising outside the workplace may have been making an important contribution to ongoing symptoms in these subjects.

Occupational cancer in the United Kingdom.
Coggon, D
1999-01-01
Most of the known occupational hazards of cancer have occurred in the United Kingdom. Over recent decades a contraction of manufacturing industry and legal controls on carcinogens have led to reductions in exposure, but cases continue to occur, often as a consequence of exposures 20 or more years ago. By far the most important occupational cause of cancer in the United Kingdom is asbestos, which currently accounts for some 600 cases of mesothelioma and perhaps 100 cases of bronchial carcinoma per year. Recent trends suggest that the number of mesothelioma cases attributable to asbestos will increase over the next few decades. Exposure to sunlight in outdoor work may cause several hundred cases of nonmelanomatous skin cancer per year, and occupational exposure to polycyclic aromatic hydrocarbons could be responsible for a similar number of skin and lung tumors. Other known occupational hazards of cancer are unlikely to account for more than 100 cases per year in total. PMID:10350506

Recent work found that soldering CdTe quantum dots together with a molecular CdTe polymer yielded field-effect transistors with much greater electron mobility than quantum dots alone. We present a computational study of the CdTe polymer using the active-space variational two-electron reduced density matrix (2-RDM) method. While analogous complete active-space self-consistent field (CASSCF) methods scale exponentially with the number of active orbitals, the active-space variational 2-RDM method exhibits polynomial scaling. A CASSCF calculation using the (48o,64e) active space studied in this paper requires 10 24 determinants and is therefore intractable, while the variational 2-RDM method in the same active space requires only 2.1 × 10 7 variables. Natural orbitals, natural-orbital occupations, charge gaps, and Mulliken charges are reported as a function of polymer length. The polymer, we find, is strongly correlated, despite possessing a simple sp 3 -hybridized bonding scheme. Calculations reveal the formation of a nearly saturated valence band as the polymer grows and a charge gap that decreases sharply with polymer length.

[Some aspects regarding occupational health in small and middle enterprises].
Bîclea, Carmen; Silion, I
2010-01-01
The objective of the study was to assess occupational health services in small and medium enterprises (SME's) in Bacău, between 2007 and 2008, in order to increase the quality of services' management. Five hundred seventy nine SME's with 21,815 employees have been studied, with a number of employees varying from ten to 250 per enterprise. About 4478 employees, out of which 587 with different occupational exposures, have no occupational health services provided on a contract basis. The high number of occupational diseases and work related accidents in SME's show a low level of concern for occupational health and safety matters, compared to big enterprises. The employees' opinions showed that the role of occupational health is not known, there is no concern for the medical adaptation of new employees or old employees rehired after a long break, the employees do not consult occupational health services on their own accord. The occupational services do not fully satisfy the need. The study offers useful data to physicians and SME's management in order to improve the occupational health management.

Education on human rights will place occupational therapists in a strong position to address societal inequities that limit occupational engagement for many client groups. The imminent changes to the Minimum Standard for the Education of Occupational Therapists engender efforts towards social change and will require university-level human rights education. This education might enhance the profession's influence on disadvantaging social structures in order to effect social change. To contribute to the evidence base for social change education in occupational therapy, this research aims to understand the knowledge, skills, confidence and learning experiences of occupational therapy students who completed a human rights course. Final year occupational therapy students responded to questionnaires which included listing human rights, a human rights scale measuring knowledge and confidence for working towards human rights, and open questions. Numbers of rights listed, knowledge scores and confidence scores were calculated. Responses to the open questions were thematically analysed. After completing a human rights course, students had good knowledge and moderate confidence to work with human rights. Three themes were identified including 'learning about human rights', 'learning about structural, societal and global perspectives on occupational engagement' and 'learning how occupational therapists can work with groups, communities and populations: becoming articulate and empowered'. Human rights education fosters the development of occupational therapists who are skilled, knowledgeable, confident and empowered to address occupational injustices, according to these research findings. To develop a more occupationally just global society, education that considers iniquitous social structures and human rights is necessary. © 2016 Occupational Therapy Australia.

Occupational Pesticide Exposures and Respiratory Health
Ye, Ming; Beach, Jeremy; Martin, Jonathan W.; Senthilselvan, Ambikaipakan
2013-01-01
Pesticides have been widely used to control pest and pest-related diseases in agriculture, fishery, forestry and the food industry. In this review, we identify a number of respiratory symptoms and diseases that have been associated with occupational pesticide exposures. Impaired lung function has also been observed among people occupationally exposed to pesticides. There was strong evidence for an association between occupational pesticide exposure and asthma, especially in agricultural occupations. In addition, we found suggestive evidence for a link between occupational pesticide exposure and chronic bronchitis or COPD. There was inconclusive evidence for the association between occupational pesticide exposure and lung cancer. Better control of pesticide uses and enforcement of safety behaviors, such as using personal protection equipment (PPE) in the workplace, are critical for reducing the risk of developing pesticide-related symptoms and diseases. Educational training programs focusing on basic safety precautions and proper uses of personal protection equipment (PPE) are possible interventions that could be used to control the respiratory diseases associated with pesticide exposure in occupational setting.

Occupational Respiratory Cancer in Korea
Kim, Hyoung Ryoul
2010-01-01
Malignant mesothelioma and lung cancer are representative examples of occupational cancer. Lung cancer is the leading cause of cancer death, and the incidence of malignant mesothelioma is expected to increase sharply in the near future. Although information about lung carcinogen exposure is limited, it is estimated that the number of workers exposed to carcinogens has declined. The first official case of occupational cancer was malignant mesothelioma caused by asbestos exposure in the asbestos textile industry in 1992. Since then, compensation for occupational respiratory cancer has increased. The majority of compensated lung cancer was due to underlying pneumoconiosis. Other main causative agents of occupational lung cancer included asbestos, hexavalent chromium, and crystalline silica. Related jobs included welders, foundry workers, platers, plumbers, and vehicle maintenance workers. Compensated malignant mesotheliomas were associated with asbestos exposure. Epidemiologic studies conducted in Korea have indicated an elevated risk of lung cancer in pneumoconiosis patients, foundry workers, and asbestos textile workers. Occupational respiratory cancer has increased during the last 10 to 20 yr though carcinogen-exposed population has declined in the same period. More efforts to advance the systems for the investigation, prevention and management of occupational respiratory cancer are needed. PMID:21258597

The discovery of magic numbers led to the shell model. They indicated closure of major shells and are robust: proton magic numbers are rather independent of the occupation of neutron orbits and vice versa. Recently the magic property became less stringent and we hear a lot about the discovery of new magic numbers. These, however, indicate sub-shell closures and strongly depend on occupation numbers and hence, may be called quasi-magic numbers. Some of these have been known for many years and the mechanism for their appearance as well as disappearance, was well understood within the simple shell model. The situationmore » will be illustrated by a few examples which demonstrate the simple features of the shell model. Will this simplicity emerge from the complex computations of nuclear many-body theory?.« less

Occupational injuries in Bahrain.
al-Arrayed, A; Hamza, A
1995-10-01
A study was conducted to show the problem of occupational injuries in Bahrain and try to highlight some solutions that may help to prevent or reduce workplace hazards. The data for occupational injuries between 1988 to 1991 from the social insurance records were reviewed and analysed. The data were summarized, grouped and tabulated according to age, sex, nationality, work place, type of injuries, cause and site of injury. Data were analysed statistically, frequencies were computed and results represented graphically. The study shows that there was a decline in the number of injuries in 1990 and 1991 due to a slow-down of economic activities in general in the Arabian Gulf region during the Gulf War. It also shows that Asian workers are at a high risk of occupational injuries.

Implications of Vehicle Roll Direction on Occupant Ejection and Injury Risk
Gloeckner, D. Claire; Moore, Tara L. A.; Steffey, Duane; Bare, Cleve; Corrigan, Catherine Ford
2006-01-01
Vehicle roll direction and occupant position have been shown to affect occupant kinematics. Data from NASS-CDS were analyzed for risk of serious or greater injuries and ejection with respect to the position of the occupant (near side or far side). The risk of AIS 3+ injuries was higher for unrestrained occupants, for ejected occupants, for occupants involved in rollovers with higher numbers of quarter turns, and for far side occupants. Near side occupants had an increased risk of partial ejection in rollovers consisting of one complete roll or less. Occupant roll direction did not affect risk of complete ejection. PMID:16968635

Occupational stress and related factors among surgical residents in Korea.
Kang, Sanghee; Jo, Hye Sung; Boo, Yoon Jung; Lee, Ji Sung; Kim, Chong Suk
2015-11-01
The application rate for surgical residents in Korea has continuously decreased over the past few years. The demanding workload and the occupational stress of surgical training are likely causes of this problem. The aim of this study was to investigate occupational stress and its related factors in Korean surgical residents. With the support of the Korean Surgical Society, we conducted an electronic survey of Korean surgical residents related to occupational stress. We used the Korean Occupational Stress Scale (KOSS) to measure occupational stress. We analyzed the data focused on the stress level and the factors associated with occupational stress. The mean KOSS score of the surgical residents was 55.39, which was significantly higher than that of practicing surgeons (48.16, P < 0.001) and the average score of specialized professionals (46.03, P < 0.001). Exercise was the only factor found to be significantly associated with KOSS score (P = 0.001) in univariate analysis. However, in multiple linear regression analysis, the mean number of assigned patients, resident occupation rate and exercise were all significantly associated with KOSS score. Surgical residents have high occupational stress compared to practicing surgeons and other professionals. Their mean number of assigned patients, resident recruitment rate and exercise were all significantly associated with occupational stress for surgical residents.

In industrializing countries, occupational safety and health have been affected by globalization. However, a lack of reliable data prevents evaluation of this situation. Therefore, we examined industrial distributions and risks of severe occupational injuries among workers in Thailand, which is one of the few industrializing countries that compiles nationwide data. Data on workers who made claims for occupational injuries from 2007 to 2009 were extracted from the Workmen's Compensation Fund records in Thailand. Among 501,334 claimants, we evaluated the industrial distributions of severe occupational injuries (i.e., permanent disability and death). We then examined the associations between industry and those injuries, using proportionate ratios (PRs) between each industrial category and the overall distribution of occupational injuries. The number of workers in manufacturing making claims for severe occupational injuries was the largest among all industrial categories (319,114/501,334 injuries), although the total number of occupational injuries recently declined. Additionally, workers in manufacturing experienced severe occupational injuries more often compared with the overall distribution of occupational injuries. The PRs (95% confidence interval) for manufacturing were 1.17 (1.14-1.20) in men and 1.33 (1.27-1.38) in women. After adjusting for individual characteristics, the results did not substantially change. Manufacturing seems to have the largest burden of occupational injuries in industrializing countries like Thailand.

Occupational therapy students' perceptions of occupational therapy.
Turpin, Merrill June; Rodger, Sylvia; Hall, Anna R
2012-10-01
An understanding of students' perceptions of occupational therapy on entry is required to recognise how professional socialisation occurs through curriculum. Findings pertain to a qualitative study investigating students' perceptions of occupational therapy upon entry to two occupational therapy programmes in Australia. Students commencing Bachelor of Occupational Therapy and Masters of Occupational Therapy Studies programmes participated in the study (n = 462). A purpose-designed questionnaire was distributed to students in the first lecture of each programme. Preliminary analysis comprised identification of keywords/phrases and coding categories were generated from patterns of keywords. Frequency counts and percentages of keywords/phrases within categories were completed. Students' responses were categorised as 'what' occupational therapists do; 'how' they do it; 'why' they do it; and 'who' they work with. In 'what' occupational therapists do students frequently described 'helping' people. Both undergraduate and graduate entry masters students used the term 'rehabilitation' to describe how occupational therapy is done, with graduate entry students occasionally responding with 'through occupation' and 'modifying the environment'. Students perceived the 'why' of occupational therapy as getting back to 'everyday activities', with some students emphasising returning to 'normal' activities or life. Regarding the 'who' category, students also thought occupational therapists worked with people with an 'injury' or 'disability'. Students entered their occupational therapy programmes with perceptions consistent with the general public's views of occupational therapy. However, graduate entry students exposed to a pre-reading package prior to entry had more advanced occupational therapy concepts than undergraduate students. © 2011 The Authors.

Occupational Deaths among Healthcare Workers
Eisenberg, Leon
2005-01-01
Recent experiences with severe acute respiratory syndrome and the US smallpox vaccination program have demonstrated the vulnerability of healthcare workers to occupationally acquired infectious diseases. However, despite acknowledgment of risk, the occupational death rate for healthcare workers is unknown. In contrast, the death rate for other professions with occupational risk, such as police officer or firefighter, has been well defined. With available information from federal sources and calculating the additional number of deaths from infection by using data on prevalence and natural history, we estimate the annual death rate for healthcare workers from occupational events, including infection, is 17–57 per 1 million workers. However, a much more accurate estimate of risk is needed. Such information could inform future interventions, as was seen with the introduction of safer needle products. This information would also heighten public awareness of this often minimized but essential aspect of patient care. PMID:16022771

Does the concentration of recent Latino immigrants into "occupational linguistic niches"--occupations with large numbers of other Spanish speakers--restrict their wage growth? On the one hand, it is possible that Latino immigrants who are concentrated in jobs with large numbers of Spanish speakers may have less on-the-job exposure to English,…

Designing occupancy studies when false-positive detections occur
Clement, Matthew
2016-01-01
1.Recently, estimators have been developed to estimate occupancy probabilities when false-positive detections occur during presence-absence surveys. Some of these estimators combine different types of survey data to improve estimates of occupancy. With these estimators, there is a tradeoff between the number of sample units surveyed, and the number and type of surveys at each sample unit. Guidance on efficient design of studies when false positives occur is unavailable. 2.For a range of scenarios, I identified survey designs that minimized the mean square error of the estimate of occupancy. I considered an approach that uses one survey method and two observation states and an approach that uses two survey methods. For each approach, I used numerical methods to identify optimal survey designs when model assumptions were met and parameter values were correctly anticipated, when parameter values were not correctly anticipated, and when the assumption of no unmodelled detection heterogeneity was violated. 3.Under the approach with two observation states, false positive detections increased the number of recommended surveys, relative to standard occupancy models. If parameter values could not be anticipated, pessimism about detection probabilities avoided poor designs. Detection heterogeneity could require more or fewer repeat surveys, depending on parameter values. If model assumptions were met, the approach with two survey methods was inefficient. However, with poor anticipation of parameter values, with detection heterogeneity, or with removal sampling schemes, combining two survey methods could improve estimates of occupancy. 4.Ignoring false positives can yield biased parameter estimates, yet false positives greatly complicate the design of occupancy studies. Specific guidance for major types of false-positive occupancy models, and for two assumption violations common in field data, can conserve survey resources. This guidance can be used to design efficient

Spatial Clustering of Occupational Injuries in Communities
Friedman, Lee; Chin, Brian; Madigan, Dana
2015-01-01
Objectives. Using the social-ecological model, we hypothesized that the home residences of injured workers would be clustered predictably and geographically. Methods. We linked health care and publicly available datasets by home zip code for traumatically injured workers in Illinois from 2000 to 2009. We calculated numbers and rates of injuries, determined the spatial relationships, and developed 3 models. Results. Among the 23 200 occupational injuries, 80% of cases were located in 20% of zip codes and clustered in 10 locations. After component analysis, numbers and clusters of injuries correlated directly with immigrants; injury rates inversely correlated with urban poverty. Conclusions. Traumatic occupational injuries were clustered spatially by home location of the affected workers and in a predictable way. This put an inequitable burden on communities and provided evidence for the possible value of community-based interventions for prevention of occupational injuries. Work should be included in health disparities research. Stakeholders should determine whether and how to intervene at the community level to prevent occupational injuries. PMID:25905838

The knowledge of specific problems of occupational cancer in Spain is scarce. The environment of the workplace has improved over the last few years after a long period distinguished by bad working conditions, incomplete legislation, and insufficient safety measures and control. It has been estimated that 3,083,479 workers (25.4% of employees) were exposed to carcinogens. The most common occupational exposures to carcinogenic agents were solar radiation, environmental tobacco smoke, silica, and wood dust. The highest number of employees were exposed to silica crystalline (404,729), diesel engine exhaust (274,321), rubber products (99,804), benzene (89,932), ethylene dibromide (81,336), agents used in furniture and cabinet making (72,068), and formaldehyde (71,189). The percentage of total cancer deaths attributed to occupational exposure was 4% (6% in men, 0.9% in women). Compared with other European countries, the incidence of lung cancer and leukemia in Spain are one of the lowest, but it is rapidly increasing. The incidence of urinary bladder and larynx cancer, on the contrary, are one of the highest. Few studies on occupational cancer have been conducted in Spain. The main problems are the availability of death certificates and the quality of the information on occupation in mortality of statistics. It is necessary to improve methods of assessment of exposures using expert hygienists and biologic markers of exposure and diseases. Reduction of cancer by limiting or avoiding exposure to known occupational carcinogens is still necessary. PMID:10350510

Building occupancy simulation and data assimilation using a graph-based agent-oriented model
NASA Astrophysics Data System (ADS)
Rai, Sanish; Hu, Xiaolin
2018-07-01
Building occupancy simulation and estimation simulates the dynamics of occupants and estimates their real-time spatial distribution in a building. It requires a simulation model and an algorithm for data assimilation that assimilates real-time sensor data into the simulation model. Existing building occupancy simulation models include agent-based models and graph-based models. The agent-based models suffer high computation cost for simulating large numbers of occupants, and graph-based models overlook the heterogeneity and detailed behaviors of individuals. Recognizing the limitations of existing models, this paper presents a new graph-based agent-oriented model which can efficiently simulate large numbers of occupants in various kinds of building structures. To support real-time occupancy dynamics estimation, a data assimilation framework based on Sequential Monte Carlo Methods is also developed and applied to the graph-based agent-oriented model to assimilate real-time sensor data. Experimental results show the effectiveness of the developed model and the data assimilation framework. The major contributions of this work are to provide an efficient model for building occupancy simulation that can accommodate large numbers of occupants and an effective data assimilation framework that can provide real-time estimations of building occupancy from sensor data.

To conduct a retrospective 15-year study to monitor trends in the number of employees at risk for occupational tuberculosis (TB) (levels III and IV) in the Slovak Republic, and in particular in the sector of economic activities Q (health care and social assistance). Furthermore, to analyze reported cases of occupational TB and to compare the incidence and sex-specific and age-specific prevalence with the data reported in the Czech Republic. Data on the number of employees at risk of exposure to occupational TB were derived from the Automated Risk Classification System of the Slovak Republic. Data on cases of occupational TB were taken from health statistics (Institute of Health Information and Statistics/National Health Information Center in the Slovak Republic and the National Institute of Public Health in the Czech Republic). A retrospective analysis was conducted (for 1998-2012) of reported cases of occupational TB, selected from Article 24 of the List of occupational diseases (infectious and parasitic diseases except tropical infectious and parasitic diseases and diseases transmissible from animals to humans). The selection criterion was a TB diagnosis according to ICD-10. In the Czech Republic, the data were derived from Article 5.1.02 (tuberculosis), Chapter V. of the List of Occupational Diseases. The data obtained were analyzed by methods of descriptive statistics. The numbers of employees with a level III risk of exposure to occupational TB in the Slovak Republic declined by 30% over the 15 years of study and by 40% in category Q. In 2012, 2027 employees were classified in category III and 1442 of them belonged to group Q. Females accounted for 81-84% of employees at risk of exposure to occupational TB. Eighty-six and 181 cases of occupational TB were reported in the Slovak Republic and in the Czech Republic, respectively, in 1998-2012, with the incidence showing a downward trend in both countries. TB of the respiratory tract was reported most often (83

The study examined the effects of office space occupation, psychosocial work characteristics, and environmental satisfaction on physical and mental health of office workers in small-sized and open-plan offices as well as possible underlying mechanisms. Office space occupation was characterized as number of persons per one enclosed office space. A total of 207 office employees with similar jobs in offices with different space occupation were surveyed regarding their work situation (psychosocial work characteristics, satisfaction with privacy, acoustics, and control) and health (psychosomatic complaints, irritation, mental well-being, and work ability). Binary logistic and linear regression analyses as well as bootstrapped mediation analyses were used to determine associations and underlying mechanisms. Employee health was significantly associated with all work characteristics. Psychosocial work stressors had the strongest relation to physical and mental health (OR range: 1.66-3.72). The effect of office space occupation on employee health was mediated by stressors and environmental satisfaction, but not by psychosocial work resources. As assumed by sociotechnical approaches, a higher number of persons per enclosed office space was associated with adverse health effects. However, the strongest associations were found with psychosocial work stressors. When revising office design, a holistic approach to work (re)design is needed. © 2015 John Wiley & Sons A/S.

Few studies have compared water exposure between different occupations in the general population. To investigate and compare the extent of occupational water exposure, with a focus on service, healthcare and production occupations previously classified as involving a high risk for hand eczema. In two public health surveys (2006 and 2010), a validated question regarding occupational water exposure was answered by 18 342 and 15,736 gainfully employed individuals, respectively. Exposure for ≥ 0.5 h/day was reported by 17.5% and 16.3% (p = 0.020) for the respective years, and exposure for > 2 h/day by 7.8% and 7.7% (p = 0.73). Exposure in women was almost twice as high as in men for both years (p ≤ 0.001) and exposure levels (p < 0.001). Exposure for > 2 h/day was more common in high-risk occupations in service and healthcare than in non-high-risk occupations [prevalence proportion ratios of 16.7 (95%CI: 14.0-20.0) and 8.3 (95%CI: 6.9-9.9), respectively]. Exposure was highest in service occupations, where 44.6% reported exposure for > 2 h/day in 2010, and kitchen work, cleaning and hairdressing dominated. In healthcare, the corresponding figure was 22.0%. Challenging differences in water exposure between occupational groups were found, and extensive water exposure was reported in a number of occupations previously classified as involving a high risk for hand eczema. © 2015 John Wiley & Sons A/S.

Fatal occupational injuries in Taiwan, 1994-2005.
Ho, Shu-Chen; Wang, Li-Yu; Ho, Chi-Kung; Yang, Chun-Yuh
2010-04-01
This study examines the trends in rates of fatal occupational injuries in Taiwan by demographic group and occupation for 1994-2005. Data on deaths due to injuries at work from 1994 through 2005 were obtained from the Department of Health which is responsible for the death registration system in Taiwan. Employment data, which were used as the denominators of fatality rates in this study, were retrieved from the Directorate-General of Budget and Accounting Statistics 'Employment and Earnings' database. A Poisson regression model was used to examine the trends in rates of fatal occupational injuries in various occupations while controlling for demographic characteristics. Overall fatal occupational injury rates declined during the study period among all demographic groups and occupations. Adjusted annual changes in rates of fatal injuries ranged from a decrease of 13.6% a year in machine operators/related workers to a decrease of 35.9% in clerks. The annual decrement was faster for males than for females and for older workers compared to young workers. Despite declining rates, the number of fatal occupational injuries in Taiwan remains significant because of the growing work force. Future research should focus on the disparities in fatal injury trends.

Occupant-to-occupant contact injury in motor vehicle crashes.
Viano, David C; Parenteau, Chantal S
2017-10-03
This is a descriptive study of the frequency and risk of occupant-to-occupant contact injury by crash type and occupant age. It focused on rear impacts because of a recent Senate inquiry. 1994-2013 NASS-CDS data were used to investigate the effects of occupant-to-occupant contact on the risk of serious-to-fatal injury (Abbreviated Injury Scale [AIS] 3+) by crash type and age group. NASS-CDS in-depth cases were analyzed to identify crash circumstances for AIS 3+ occupant-to-occupant contact injury in rear crashes. Serious injury (AIS 3+) due to occupant-to-occupant contact was uncommon. It represented only 0.84% of all AIS 3+ injury for all age groups. The overall risk of AIS 3+ occupant-to-occupant contact injury was 0.042 ± 0.007%. The highest incidence was in side impacts (69.8%) followed by rollovers (22.9%). Occupant-to-occupant contact injury risk was lower in rear impacts than in other crash types, at 0.0078 ± 0.0054%. The highest risk of AIS 3+ injury with occupant-to-occupant was for the <9-year-old age group when compared to other age groups for all crash types. The risk was 0.051 ± 0.026%, representing 2.69% of all AIS 3+ injury in the <9-year-old age group. Only 4.2% of AIS 3+ occupant-to-occupant contact injury occurred to children <9 years old in rear impacts. The corresponding injury risk was lowest in rear impacts, at 0.014 ± 0.014%%, when compared to other crash types. The analysis of in-depth NASS-CDS cases of occupant-to-occupant contact injury in children< 9 years old involved in rear impacts identified very severe collisions in older model vehicles with deformation of the occupant compartment and yielding front seats as main factors for the contact injury. Front seat occupants injuring rear-seated children was not identified in the in-depth NASS-CDS cases. AIS 3+ occupant-to-occupant contact injury occurs primarily in side impacts and rollovers. Most contact injury is to adults (89.4% incidence). Occupant-to-occupant contact injury to

Chronic cough due to occupational factors
Groneberg, David A; Nowak, Dennis; Wussow, Anke; Fischer, Axel
2006-01-01
Within the large variety of subtypes of chronic cough, either defined by their clinical or pathogenetic causes, occupational chronic cough may be regarded as one of the most preventable forms of the disease. Next to obstructive airway diseases such as asthma or chronic obstructive pulmonary disease, which are sometimes concomitant with chronic cough, this chronic airway disease gains importance in the field of occupational medicine since classic fiber-related occupational airway diseases will decrease in the future. Apart from acute accidents and incidental exposures which may lead to an acute form of cough, there are numerous sources for the development of chronic cough within the workplace. Over the last years, a large number of studies has focused on occupational causes of respiratory diseases and it has emerged that chronic cough is one of the most prevalent work-related airway diseases. Best-known examples of occupations related to the development of cough are coal miners, hard-rock miners, tunnel workers, or concrete manufacturing workers. As chronic cough is often based on a variety of non-occupational factors such as tobacco smoke, a distinct separation into either occupational or personally -evoked can be difficult. However, revealing the occupational contribution to chronic cough and to the symptom cough in general, which is the commonest cause for the consultation of a physician, can significantly lead to a reduction of the socioeconomic burden of the disease.

Job-related diseases and occupations within a large workers' compensation data set.
Leigh, J P; Miller, T R
1998-03-01
The objective of this report is to describe workers' job-related diseases and the occupations associated with those diseases. The methods include aggregation and analysis of job-related disease and occupation data from the Bureau of Labor Statistics' Supplementary Data System (SDS) for 1985 and 1986--the last years of data available with workers' compensation categories: death, permanent total, permanent partial, and temporary total and partial. Diseases are ranked according to their contribution to the four workers' compensation (WC) categories and also ranked within occupations according to the number of cases. Occupations are ranked according to their contribution to specific diseases within one of the four categories. The following diseases comprise the greatest numbers of deaths: heart attacks, asbestosis, silicosis, and stroke. Within the permanent total category, the diseases with the greatest contributions are heart attack, silicosis, strokes, and inflammation of the joints. For the permanent partial category, they are hearing loss, inflammation of joints, carpal tunnel syndrome, and heart attacks. For the temporary total and partial category, they are: inflammation of joints, carpal tunnel syndrome, dermatitis, and toxic poisoning. Hearing loss or inflammation of joints are associated with more than 300 occupations. Circulatory diseases comprise a larger share of job-related diseases than is generally acknowledged. Occupations contributing the most heart attack deaths are truck drivers, managers, janitors, supervisors, firefighters, and laborers. Ratios of numbers of deaths to numbers of disabilities are far higher for illnesses than injuries. Occupations that are consistent in their high ranking on most lists involving a variety of conditions include nonconstruction laborers, janitors, and construction laborers. The large SDS, though dated, provides a tentative national look at the broad spectrum of occupational diseases as defined by WC and the

The trend of occupational injuries in Korea from 2001 to 2010.
Rhee, Kyung Yong; Choe, Seong Weon; Kim, Young Sun; Koo, Kwon Ho
2013-03-01
This study is planned to assess the trend of occupational injuries in Korea from 2001 to 2010. Ten years of occupational injuries, from 2001 to 2010, were analyzed in order to investigate the changing profiles according to the various characteristics of injuries; economic sectors, age of the injured, and type of injuries. The changing profile of occupational injuries was investigated by comparison with an index-created relative value based on the number of cases of reference category. The fatalities of construction, forest, agriculture, and service show the increasing trend. The nonfatal occupational injuries of the manufacturing sector were higher than those of other sectors in every year but the fatal occupational injuries of construction workers were higher than those of the manufacturing sector. Occupational injuries occurring due to amputation and those of slip and trip increased. The number of occupational injuries for the worker groups of 24 years old and below decreased and 45 years old and above increased. In comparison to the figure of fall from height, the figures of slip and trip or caught in equipment are higher in every calendar year. This study find out construction, forest, agriculture, and service sectors, aged worker with 45 years old and over can be target population for the strategies of occupational safety.

The Study Model for Future Occupational Health (funded by a research grant from the Ministry of Health, Welfare and Labor) is a joint research project involving various organizations and agencies undertaken from 2002 to 2004. Society has undergone a dramatic transformation due to technological developments and internationalization. At the same time a low birth rate and an aging population have resulted in an increase in both the percentage of workers experiencing strong anxiety and stress in relation to their jobs and the working environment and the number of suicides. As a natural consequence, occupational health services are now expected to provide EAP, consulting and other functions that were formerly considered outside the realm of occupational health. In consideration of this background, the present study propose the following issues to provide a model for future occupational health services that meet the conditions presently confronted by each worker. 1. How to provide occupational health services and occupational physicians' services: 1) a basic time of 20 minutes of occupational health services per year should be allotted to each worker and to all workers; 2) the obligatory regulations should be revised to expand the obligation from businesses each with 50 or more employees under the present laws to businesses each with 30 or more employees. 2. Providers of occupational health services and occupational physicians' services: (1) reinforcement of outside occupational health agencies; (2) fostering occupational health consultant firms; (3) development of an institute of occupational safety and health; (4) support of activities by authorized occupational physicians in the field; (5) expanding of joint selection of occupational physicians including subsidy increase and the extension of a period of subsidy to five hears; (6) licensing of new entry into occupational health undertaking. 3. Introduction of new report system: (1) establishment of the obligation to

A Method for Modeling Household Occupant Behavior to Simulate Residential Energy Consumption
DOE Office of Scientific and Technical Information (OSTI.GOV)
Johnson, Brandon J; Starke, Michael R; Abdelaziz, Omar
2014-01-01
This paper presents a statistical method for modeling the behavior of household occupants to estimate residential energy consumption. Using data gathered by the U.S. Census Bureau in the American Time Use Survey (ATUS), actions carried out by survey respondents are categorized into ten distinct activities. These activities are defined to correspond to the major energy consuming loads commonly found within the residential sector. Next, time varying minute resolution Markov chain based statistical models of different occupant types are developed. Using these behavioral models, individual occupants are simulated to show how an occupant interacts with the major residential energy consuming loadsmore » throughout the day. From these simulations, the minimum number of occupants, and consequently the minimum number of multiple occupant households, needing to be simulated to produce a statistically accurate representation of aggregate residential behavior can be determined. Finally, future work will involve the use of these occupant models along side residential load models to produce a high-resolution energy consumption profile and estimate the potential for demand response from residential loads.« less

Occupational inhalative exposures contribute to a significant proportion of obstructive airway diseases (OAD), namely chronic obstructive pulmonary disease (COPD) and asthma. The number of occupational OAD in the German industrial sector for the year 2003 are presented. Other analyses of surveillance data were retrieved from Medline. Most confirmed reports of OAD are cases of sensitizer induced occupational asthma (625 confirmed cases) followed by COPD in coal miners (414 cases), irritant induced occupational asthma (156 cases), and isocyanate asthma (54 cases). Main causes of occupational asthma in Germany comprise flour/flour constituents (35.9%), food/feed dust (9.0%), and isocyanates (6.5%). Flour and grainmore » dust is a frequent cause of occupational asthma in most European countries and South Africa. Isocyanates are still a problem worldwide. Although wide differences in the estimated incidences between countries exist due to deficits in the coverage of occupational OAD, the high numbers necessitate improvement of preventive measures.« less

Occupational illnesses within two national data sets.
Leigh, J P; Miller, T R
1998-01-01
To describe occupational illness data in two large data sets, two national data sets were aggregated, and the numbers, percentages, and rates of cases of occupational illnesses were determined. Job-related illness data were from Bureau of Labor Statistics documents containing Annual Survey and Census of Fatal Occupational Injury data. A severity index was created to assess the overall burden of a disease. The index multiplies the number of cases times the median days lost. Circulatory disease accounted for 85% of the deaths in the Census and at least 80% in the Annual Survey. More fatal myocardial infarctions occurred on Monday than on any other day. Low-paying occupations had the most myocardial infarctions: operators, laborers, and truck drivers; high-paying occupations had the least: executives, administrators, and managers. Carpal tunnel syndrome and hearing loss accounted for more morbidity, measured by cases and days lost, than any other illness. Persons at great risk for carpal tunnel syndrome included dental hygienists, butchers, sewing machine operators, and dentists. Mental disorders generated more morbidity than is generally acknowledged. Neurotic reactions to stress were highest in the transportation and public utility industries, as well as in finance, insurance, and real estate. Manufacturing contributed far more cases than any other industry. Industries generating significant asbestos-related deaths included construction and boat building. Ninety-three percent of all illness fatalities were among men. Few African Americans died from coal-workers' pneumoconiosis. Illness cases increased much faster than injury cases in recent years. The two data sets provide insights into the incidences and prevalences of occupational illnesses, but underestimate the burden of job-related illnesses.

Observations of seating position of front seat occupants relative to the side of the vehicle.
Dinas, Arthur; Fildes, Brian N
2002-01-01
This study was an on-road observational study of the seating position and limb position of front seat occupants relevant to the side of the car for a representative sample of occupants during straight road driving and turning manoeuvres. A video camera captured over 650 front-on images of passenger car occupants in Metropolitan Melbourne. Results showed a significant numbers of occupants were seated out-of-position while travelling on the road and that a number of these were seated in a manner that may possibly result in injury from the deployment of a side airbag. This was particularly so while turning, a situation common in many side impacts. A substantial number of front seat occupants' arms were exposed to severe injury in the event of a side impact crash. These findings highlight a number of aspects of seating behaviour of driver and front passengers that need to be taken into account when designing side impact airbags.

Organisational factors and occupational balance in working parents in Sweden.
Borgh, Madeleine; Eek, Frida; Wagman, Petra; Håkansson, Carita
2018-05-01
Parents with small children constitute a vulnerable group as they have an increased risk of sick leave due to stress-related disorders compared to adults without children. It has been shown that mothers and fathers to small children together spend more time in paid work than any other group, which could create negative stress and an experience of low occupational balance. The aim of this study was to examine associations between organisational factors and occupational balance among parents with small children in Sweden. Data were collected by a survey including questions about occupational balance, organisational factors and age, sex, employment rate, work position, monthly household income, number of children at home, separation/divorce last five years and overtime. The total number of parents included in this study was 718 (490 mothers and 228 fathers). Logistic regression models were applied to examine the odds ratios for occupational balance in relation to organisational factors. Parents who experienced positive attitudes towards parenthood and parental leave among colleagues and managers were more likely to experience high occupational balance than parents who experienced negative or neutral attitudes. Having a clear structure for handover when absent from work was also strongly associated with high occupational balance. The result of the present study indicates that some organisational factors could be important for the occupational balance of parents with small children.

We collected information necessary for conducting occupational health activities in Thailand with regard to occupational safety and health management systems (OSHMS). Based on an information collection check sheet developed in our previous research, we conducted a literature research and visited four local business bases, one ISO certification body and two higher educational institutions. The legal framework concerning occupational health in Thailand consists of the Occupational Safety, Health and Environment Act of 2011 and 13 ordinances from the Ministry of Labor under that act. The original OSHMS standards for Thailand have been published, and the number of companies, especially large ones, introducing systems conforming to these standards has increased in recent years. For occupational health specialists, there are training programs for specialized occupational health physicians, professional safety officers and occupational nurses. Professional safety officers also play a central role in occupational health in the workplace. In Thailand, it is necessary to ensure compliance with related acts and regulations, and to conduct voluntary activities that satisfy workplace conditions as based on the OSHMS standards. Additionally, to improve occupational health performance, it is essential to use high-quality external services and/or occupational health professionals. Headquarters of Japanese companies have considered taking countermeasures such as recommending active use of professional safety officers, as well as issuing global standards.

Patterns of daily occupations (PDO) and occupational balance (OB) are recurring phenomena in the literature. Both are related with health and well-being, which makes them central in occupational therapy practice and occupational science. The aim was to review how PDO and OB are described in the literature, to propose a view of how the two constructs may be linked, and elaborate on how such a view may benefit occupational science and occupational therapy. The literature was analysed by latent and manifest content analysis and comparative analysis. The findings were summarized in a model, framing PDO as the more objective and OB as the more subjective result from an interaction between personal preferences and environmental influences. The proposed model does not assume a cause-effect relationship between the targeted constructs, rather a mutual influence and a joint reaction to influencing factors. Indicators of PDO and OB were identified, as well as tools for assessing PDO and OB. The authors propose that discerning PDO and OB as separate but interacting phenomena may be useful in developing a theoretical discourse in occupational science and enhancing occupational therapy practice. Although the scope of this study was limited, the proposed view may hopefully inspire further scrutiny of constructs.

Designing occupancy studies: general advice and allocating survey effort
MacKenzie, D.I.; Royle, J. Andrew
2005-01-01
1. The fraction of sampling units in a landscape where a target species is present (occupancy) is an extensively used concept in ecology. Yet in many applications the species will not always be detected in a sampling unit even when present, resulting in biased estimates of occupancy. Given that sampling units are surveyed repeatedly within a relatively short timeframe, a number of similar methods have now been developed to provide unbiased occupancy estimates. However, practical guidance on the efficient design of occupancy studies has been lacking. 2. In this paper we comment on a number of general issues related to designing occupancy studies, including the need for clear objectives that are explicitly linked to science or management, selection of sampling units, timing of repeat surveys and allocation of survey effort. Advice on the number of repeat surveys per sampling unit is considered in terms of the variance of the occupancy estimator, for three possible study designs. 3. We recommend that sampling units should be surveyed a minimum of three times when detection probability is high (> 0.5 survey-1), unless a removal design is used. 4. We found that an optimal removal design will generally be the most efficient, but we suggest it may be less robust to assumption violations than a standard design. 5. Our results suggest that for a rare species it is more efficient to survey more sampling units less intensively, while for a common species fewer sampling units should be surveyed more intensively. 6. Synthesis and applications. Reliable inferences can only result from quality data. To make the best use of logistical resources, study objectives must be clearly defined; sampling units must be selected, and repeated surveys timed appropriately; and a sufficient number of repeated surveys must be conducted. Failure to do so may compromise the integrity of the study. The guidance given here on study design issues is particularly applicable to studies of species

Occupation and cancer in Britain
Rushton, L; Bagga, S; Bevan, R; Brown, T P; Cherrie, J W; Holmes, P; Fortunato, L; Slack, R; Van Tongeren, M; Young, C; Hutchings, S J
2010-01-01
Background: Prioritising control measures for occupationally related cancers should be evidence based. We estimated the current burden of cancer in Britain attributable to past occupational exposures for International Agency for Research on Cancer (IARC) group 1 (established) and 2A (probable) carcinogens. Methods: We calculated attributable fractions and numbers for cancer mortality and incidence using risk estimates from the literature and national data sources to estimate proportions exposed. Results: 5.3% (8019) cancer deaths were attributable to occupation in 2005 (men, 8.2% (6362); women, 2.3% (1657)). Attributable incidence estimates are 13 679 (4.0%) cancer registrations (men, 10 063 (5.7%); women, 3616 (2.2%)). Occupational attributable fractions are over 2% for mesothelioma, sinonasal, lung, nasopharynx, breast, non-melanoma skin cancer, bladder, oesophagus, soft tissue sarcoma, larynx and stomach cancers. Asbestos, shift work, mineral oils, solar radiation, silica, diesel engine exhaust, coal tars and pitches, occupation as a painter or welder, dioxins, environmental tobacco smoke, radon, tetrachloroethylene, arsenic and strong inorganic mists each contribute 100 or more registrations. Industries and occupations with high cancer registrations include construction, metal working, personal and household services, mining, land transport, printing/publishing, retail/hotels/restaurants, public administration/defence, farming and several manufacturing sectors. 56% of cancer registrations in men are attributable to work in the construction industry (mainly mesotheliomas, lung, stomach, bladder and non-melanoma skin cancers) and 54% of cancer registrations in women are attributable to shift work (breast cancer). Conclusion: This project is the first to quantify in detail the burden of cancer and mortality due to occupation specifically for Britain. It highlights the impact of occupational exposures, together with the occupational circumstances and industrial

2013-01-01
Objectives This study is planned to assess the trend of occupational injuries in Korea from 2001 to 2010. Methods Ten years of occupational injuries, from 2001 to 2010, were analyzed in order to investigate the changing profiles according to the various characteristics of injuries; economic sectors, age of the injured, and type of injuries. The changing profile of occupational injuries was investigated by comparison with an index-created relative value based on the number of cases of reference category. Results The fatalities of construction, forest, agriculture, and service show the increasing trend. The nonfatal occupational injuries of the manufacturing sector were higher than those of other sectors in every year but the fatal occupational injuries of construction workers were higher than those of the manufacturing sector. Occupational injuries occurring due to amputation and those of slip and trip increased. The number of occupational injuries for the worker groups of 24 years old and below decreased and 45 years old and above increased. In comparison to the figure of fall from height, the figures of slip and trip or caught in equipment are higher in every calendar year. Conclusion This study find out construction, forest, agriculture, and service sectors, aged worker with 45 years old and over can be target population for the strategies of occupational safety.

Occupational cancer research methods was identified in 1996 as 1 of 21 priority research areas in the National Occupational Research Agenda (NORA). To implement NORA, teams of experts from various sectors were formed and given the charge to further define research needs and develop strategies to enhance or augment research in each priority area. This article is a product of that process. Focus on occupational cancer research methods is important both because occupational factors play a significant role in a number of cancers, resulting in significant morbidity and mortality, and also because occupational cohorts (because of higher exposure levels) often provide unique opportunities to evaluate health effects of environmental toxicants and understand the carcinogenic process in humans. Despite an explosion of new methods for cancer research in general, these have not been widely applied to occupational cancer research. In this article we identify needs and gaps in occupational cancer research methods in four broad areas: identification of occupational carcinogens, design of epidemiologic studies, risk assessment, and primary and secondary prevention. Progress in occupational cancer will require interdisciplinary research involving epidemiologists, industrial hygienists, toxicologists, and molecular biologists. PMID:12524210

[Projection of prisoner numbers].
Metz, Rainer; Sohn, Werner
2015-01-01
The past and future development of occupancy rates in prisons is of crucial importance for the judicial administration of every country. Basic factors for planning the required penal facilities are seasonal fluctuations, minimum, maximum and average occupancy as well as the present situation and potential development of certain imprisonment categories. As the prisoner number of a country is determined by a complex set of interdependent conditions, it has turned out to be difficult to provide any theoretical explanations. The idea accepted in criminology for a long time that prisoner numbers are interdependent with criminal policy must be regarded as having failed. Statistical and time series analyses may help, however, to identify the factors having influenced the development of prisoner numbers in the past. The analyses presented here, first describe such influencing factors from a criminological perspective and then deal with their statistical identification and modelling. Using the development of prisoner numbers in Hesse as an example, it has been found that modelling methods in which the independent variables predict the dependent variable with a time lag are particularly helpful. A potential complication is, however, that for predicting the number of prisoners the different dynamics in German and foreign prisoners require the development of further models.

Occupational asthma is an avoidable form of asthma. In Finland, the diagnosis of occupational asthma entitles substantial compensation to the employee. The diagnostics are based on symptoms, exposure assessment, allergologic investigations, follow-up of peak expiratory flow (PEF) at work and at home and, in many cases, specific challenge tests. To study the causative agents of occupational asthma in Finland. The causative agents and the numbers of new occupational asthma cases notified to the Finnish Register of Occupational Diseases (FROD) during 1986-2002 are reported. The number of occupational asthma cases increased from 1986 until 1995, after which a downward trend, stabilizing during the last few years, has been observed. The majority of the cases (59%) in the beginning of the period (1986-1990) were associated with agriculture, but the percentage has fallen thereafter (42% of the cases in 1998-2002) along with the fall in the total number of cases. Since 1995, indoor moulds from water-damaged buildings have caused an increasing number of cases and have become the most important causative agents (0.5% cases, in 1986-1990 and 18% of the cases in 1998-2002). Chemicals have caused 10-30% of the cases, a decreasing number since 1990. The most important chemicals causing occupational asthma have been diisocyanates and welding fumes, followed by hairdressing chemicals and formaldehyde. The number of occupational asthma cases in Finland reached its height in the mid-1990s. The decrease in the number of total cases is because of the decrease in agriculture-associated cases, reflecting the number of employees in agriculture-associated occupations, which has greatly decreased since Finland joined the EU in 1995. An epidemic of mould-induced asthma, affecting mostly white-collar employees working in moisture-damaged buildings, has taken place since 1995.

Associations of Occupational Attributes and Excessive Drinking
Barnes, Andrew J.; Zimmerman, Frederick J.
2017-01-01
Numerous work-related drinking mechanisms have been posited and, oftentimes, examined in isolation. We combined data from over 100 occupational attributes into several factors and tested the association of these factors with measures of alcohol use. We used the NLSY79 2006 wave, a U.S. representative sample of 6,426 workers ages 41 to 49 and the 2006 Occupational Information Network database (O*NET), a nationally representative sample of nearly 1,000 occupations. We conducted exploratory factor analysis on 119 occupational attributes and found three independent workplace characteristics – physical demands, job autonomy, and social engagement - explained the majority of the variation. We then tested the association of these composite attributes with three drinking measures, before and after adjusting for gender, race/ethnicity, and a measure of human capital using count data models. We then stratified by gender and repeated our analyses. Men working in occupations with a one standard deviation higher level of physical demand (e.g. construction) reported a higher number of heavy drinking occasions (+20%, p<0.05). Job autonomy was not significantly associated with measures of alcohol use and when the combined association of higher levels of physical demand and lower levels of job autonomy was examined, modest support for job strain as a mechanism for work-related alcohol consumption was found. In our pooled sample, working in occupations with one standard deviation higher levels of social engagement was associated with lower numbers of drinking days (−9%, p<0.05) after adjustment. Physical demand and social engagement were associated with alcohol consumption measures but these relationships varied by workers’ gender. Future areas of research should include confirmatory analyses using other waves of O*Net data and replicating the current analysis in other samples of workers. If our results are validated, they suggest male workers in high physical demand

Occupational consciousness refers to ongoing awareness of the dynamics of hegemony and recognition that dominant practices are sustained through what people do every day, with implications for personal and collective health. The emergence of the construct in post-apartheid South Africa signifies the country's ongoing struggle with negotiating long-standing dynamics of power that were laid down during colonialism, and maintained under black majority rule. Consciousness, a key component of the new terminology, is framed from post-colonial perspectives - notably work by Biko and Fanon - and grounded in the philosophy of liberation, in order to draw attention to continuing unequal intersubjective relations that play out through human occupation. The paper also draws important links between occupational consciousness and other related constructs, namely occupational possibilities, occupational choice, occupational apartheid, and collective occupation. The use of the term 'consciousness' in sociology, with related or different meanings, is also explored. Occupational consciousness is then advanced as a critical notion that frames everyday doing as a potentially liberating response to oppressive social structures. This paper advances theorizing as a scholarly practice in occupational science, and could potentially expand inter or transdisciplinary work for critical conceptualizations of human occupation.

CAREX Canada: an enhanced model for assessing occupational carcinogen exposure
Peters, Cheryl E; Ge, Calvin B; Hall, Amy L; Davies, Hugh W; Demers, Paul A
2015-01-01
Objectives To estimate the numbers of workers exposed to known and suspected occupational carcinogens in Canada, building on the methods of CARcinogen EXposure (CAREX) projects in the European Union (EU). Methods CAREX Canada consists of estimates of the prevalence and level of exposure to occupational carcinogens. CAREX Canada includes occupational agents evaluated by the International Agency for Research on Cancer as known, probable or possible human carcinogens that were present and feasible to assess in Canadian workplaces. A Canadian Workplace Exposure Database was established to identify the potential for exposure in particular industries and occupations, and to create exposure level estimates among priority agents, where possible. CAREX EU data were reviewed for relevance to the Canadian context and the proportion of workers likely to be exposed by industry and occupation in Canada was assigned using expert assessment and agreement by a minimum of two occupational hygienists. These proportions were used to generate prevalence estimates by linkage with the Census of Population for 2006, and these estimates are available by industry, occupation, sex and province. Results CAREX Canada estimated the number of workers exposed to 44 known, probable and suspected carcinogens. Estimates of levels of exposure were further developed for 18 priority agents. Common exposures included night shift work (1.9 million exposed), solar ultraviolet radiation exposure (1.5 million exposed) and diesel engine exhaust (781 000 exposed). Conclusions A substantial proportion of Canadian workers are exposed to known and suspected carcinogens at work. PMID:24969047

A voluntary surveillance system was implemented in Catalonia (Spain) to ascertain the feasibility, incidence, and characteristics of occupational respiratory diseases and compare them with those of the compulsory official system. In 2002, in collaboration with the Occupational and Thoracic Societies of Catalonia, occupational and chest physicians and other specialists were invited to report, on a bimonthly basis, newly diagnosed cases of occupational respiratory diseases. Information requested on each case included diagnosis, age, sex, place of residence, occupation, suspected agent, and physician's opinion on the likelihood that the condition was work related. Compulsory official system data derived from statistics on work related diseases for possible disability benefits declared by insurance companies, which are responsible for declaring these diseases to the Autonomous Government of Catalonia. Of 142 physicians seeing patients with occupational respiratory diseases approached, 102 (74%) participated. Three hundred and fifty nine cases were reported, of which asthma (48.5%), asbestos related diseases (14.5%), and acute inhalations (12.8%) were the most common. Physicians rated 63% of suspected cases as highly likely, 28% as likely, and 8% as low likelihood. The most frequent suspected agents reported for asthma were isocyanates (15.5%), persulphates (12.1%), and cleaning products (8.6%). Mesothelioma (5.9%) was the most frequent diagnosis among asbestos related diseases. The number of acute inhalations reported was high, with metal industries (26%), cleaning services (22%), and chemical industries (13%) being the most frequently involved. The frequency of occupational respiratory diseases recorded by this voluntary surveillance system was four times higher than that reported by the compulsory official system. The compulsory scheme for reporting occupational lung diseases is seriously underreporting in Catalonia. A surveillance programme based on voluntary

The most frequent suspected agents reported for asthma were isocyanates (15.5%), persulphates (12.1%), and cleaning products (8.6%). Mesothelioma (5.9%) was the most frequent diagnosis among asbestos related diseases. The number of acute inhalations reported was high, with metal industries (26%), cleaning services (22%), and chemical industries (13%) being the most frequently involved. The frequency of occupational respiratory diseases recorded by this voluntary surveillance system was four times higher than that reported by the compulsory official system. Conclusions The compulsory scheme for reporting occupational lung diseases is seriously underreporting in Catalonia. A

[Epidemiology of occupational skin cancer due to UV-irradiation].
Diepgen, T L; Drexler, H; Schmitt, J
2012-10-01
Skin cancer induced by occupational UV-irradiation is not an official occupational disease number in the appendix of the German ordinance on occupational diseases (Berufskrankheitenverordnung (BKV) but can be recognized as a "virtually" occupational disease according to § 9 (2) of the 7th book of the German Social Code (SGB VII). Epidemiological studies have demonstrated a positive, statistically significant and relevant association between occupational UV-irradiation and the risk of squamous cell carcinoma (SCC) and actinic keratoses (AK). Outdoor workers have on average a 100% higher risk to develop SCC compared to the general population. Therefore, the prerequisites for a new occupational disease are fulfilled and SCC and AK should be reported as an occupational disease if an additional 40% occupationally-related UV-irradiation is documented and the clinical criteria are typical for work- related skin cancer. Epidemiologic evidence also indicates a significant association between work-related UV-irradiation and basal cell carcinoma (BCC) risk: however the results are less consistent and the association is weaker than with SCC. There is an urgent need for further studies in outdoor workers on BCC and lentigo maligna melanoma.

Outcomes of Occupational Self-Efficacy in Older Workers
Paggi, Michelle E.; Jopp, Daniela S.
2016-01-01
Because of the increasing number of older workers, it is important to develop models of work-related constructs for this population. The present article developed a model surrounding occupational self-efficacy, testing its relation to other factors (e.g., intrinsic job motivation), predictors (e.g., self-perceptions of aging), and outcomes (e.g., job satisfaction). Employed adults of ages 50 and older (n= 313) were recruited via organizations and social media sites. Study participants (M= 59.7, SD= 6.1, range = 50–78) volunteered to fill out an Internet survey. Occupational self-efficacy predicted job satisfaction, and intrinsic job motivation fully mediated this relationship. More negative self-perceptions of aging predicted poorer occupational self-efficacy. Occupational self-efficacy also predicted life satisfaction. Expected retirement age and job performance were unrelated to occupational self-efficacy. These findings may inform workplace interventions that seek to maintain or increase older worker job and life satisfaction. PMID:26394821

2016-04-01
The number of people passing through different indoor areas is useful in various smart structure applications, including occupancy-based building energy/space management, marketing research, security, etc. Existing approaches to estimate occupant traffic include vision-, sound-, and radio-based (mobile) sensing methods, which have placement limitations (e.g., requirement of line-of-sight, quiet environment, carrying a device all the time). Such limitations make these direct sensing approaches difficult to deploy and maintain. An indirect approach using geophones to measure floor vibration induced by footsteps can be utilized. However, the main challenge lies in distinguishing multiple simultaneous walkers by developing features that can effectively represent the number of mixed signals and characterize the selected features under different traffic conditions. This paper presents a method to monitor multiple persons. Once the vibration signals are obtained, features are extracted to describe the overlapping vibration signals induced by multiple footsteps, which are used for occupancy traffic estimation. In particular, we focus on analysis of the efficiency and limitations of the four selected key features when used for estimating various traffic conditions. We characterize these features with signals collected from controlled impulse load tests as well as from multiple people walking through a real-world sensing area. In our experiments, the system achieves the mean estimation error of +/-0.2 people for different occupant traffic conditions (from one to four) using k-nearest neighbor classifier.

Agents and trends in health care workers' occupational asthma.
Walters, G I; Moore, V C; McGrath, E E; Burge, P S; Henneberger, P K
2013-10-01
There is a disproportionately high number of cases of work-related asthma occurring in health care occupations due to agents such as glutaraldehyde, latex and cleaning products. To understand the causes and measure trends over time of occupational asthma (OA) in health care workers (HCWs). We reviewed OA notifications from the Midland Thoracic Society's Surveillance Scheme of Occupational Asthma (SHIELD) database in the West Midlands, UK, from 1991 to 2011 and gathered data on occupation, causative agent and annual number of notifications. There were 182 cases of OA in HCWs (median annual notifications = 7; interquartile range [IQR] = 5-11), representing 5-19% of annual SHIELD notifications. The modal annual notification was 20 (in 1996); notifications have declined since then, in line with total SHIELD notifications. The majority of cases (136; 75%) occurred in nursing, operating theatre, endoscopy and radiology staff. The most frequently implicated agents were glutaraldehyde (n = 69), latex (n = 47) and cleaning products (n = 27), accounting for 79% of the 182 cases. Cleaning product-related OA was an emerging cause with 22 cases after 2001 and only 5 cases between 1991 and 2000. Control measures within the UK National Health Service have seen a decline in OA in HCWs due to latex and glutaraldehyde, though OA remains a problem amongst HCWs exposed to cleaning products. Continuing efforts are required to limit the number of cases in this employment sector.

Occupational cancer is one of the most important topics in occupational health, because it can be avoided by using appropriate risk management strategies at work. However, due to the lack of suitable surveillance systems in Japan, it goes under-recognized. Burden of disease studies conducted elsewhere can be extrapolated to suggest thousands of deaths are attributable to occupational cancer in Japan. By law, about 20 kinds of cancer have been listed as occupational hazards; among those is asbestos related cancer. In fact, in recent years, thousands of asbestos related cancer cases have been compensated by the government run workers' compensation scheme for occupational accidents and diseases. On the other hand, for the other types of occupational cancer, only few cases are reported. To prevent re-emergence of occupational cancer, such as the recently publicized cholangiocarcinoma epidemics, employees, employers, medical institutions and competent authorities are strongly urged to establish better surveillance systems for occupational cancer.

[Occupational injury, a public health priority].
Benavides, Fernando G; Delclos, Jordi; Benach, Joan; Serra, Consol
2006-01-01
The aim of this review is to stimulate new ideas and actions for the prevention of this important public health problem. In 2002 and 2003, respectively, the number of non-fatal occupational injuries was 971,406 and 906,638. Thus, every day in Spain there are more than 2500 non-fatal and between 2 and 3 fatal occupational injuries. Although the profile of the at-risk worker population has changed greatly over the past decade, both quantitatively and qualitatively, the risk of occupational injury still centers on blue collar workers, whether qualified or nonqualified, in the primary and secondary sectors of economic activity. The most common mechanisms of occupational injuries are overexertion for non-fatal injuries and traffic-related for fatal events. The adverse health consequences of new types of employment, which emphasize flexibility and deregulation of the labour market, are exemplified by the association between temporary employment and increased risk of occupational injury. New injury prevention programs have emerged in the last decade, but they appear to have had limited impact. Preventive activities should focus both on working conditions at the company level (micro) as well as on employment and industrial public policies (macro). Greater evaluation is needed of these latter policies.

Ethics in biomonitoring for occupational health.
Manno, M; Sito, F; Licciardi, L
2014-12-01
Biological monitoring, i.e., the use of biomarkers for the measurement of systemic human exposure, effects and susceptibility to chemicals has increased considerably in recent years. Biomonitoring techniques, originally limited to a few metals and other chemicals in the workplace, are currently applied to a large number of exposure situations and have become a useful tool for occupational and environmental health risk assessment. Almost any biomonitoring program, however, entails a number of relevant ethical issues, which concern all the phases of the entire process, from the selection of the biomarker to the study design, from the collection, storage and analysis of the biological sample to the interpretation, communication and management of the results, from the (truly?) informed consent of the worker to the independence and autonomy of the occupational health professional. These issues require a balanced assessment of the interests and responsibilities of all the parties, the worker primarily, but also the employer, the occupational health professional, the health authorities and, for research studies on new biomarkers, also the scientists involved. Ideally, decisions of ethical relevance concerning biomarkers should be based on, and respectful of the best scientific, legal and ethical evidence available. When, however, a conflict should arise, before any decision is taken a thorough risk-benefit analysis should be done, at the beginning of the process and after listening to the workers and the management involved, by the occupational physician or scientist, based on his/her professional experience, independent judgement and individual responsibility.

Measurements of the work ability subjective assessment, using the work ability index (WAI), are widely applied in the examination of workers. The measurement results suggest that the low level of work ability, which is determined by work-burden factors, health condition, and lifestyles of persons under study, can be a predictor of earlier retirement. The aim of the study was to find out whether WAI can be used in Polish conditions and to identify personal traits and/or job characteristics and conditions of its performance that generate the risk of low work ability. The cross-sectional study embraced 669 men and 536 women at the working age, representing different occupations and exposed to various factors. They self-assessed their work ability by completing a questionnaire that allows to determine WAI values. They also characterized their jobs in terms of physical burden, occupational stress, harmful and strenuous factors, work fatigue, chronic fatigue, and lifestyle. Based on the energy expenditure and health condition (number of diseases), the work burden was objectively defined. A model of multivariate logistic regression was used to assess the effect of the analyzed factors on the risk of low or moderate work ability. The level of work ability in the study group was lower than that observed in analogous occupational groups in other European countries. The results of the analysis indicate that job characterizing factors and workers' individual traits exert a stronger effect on the level of WAI components, which reflect a subjective assessment of work abilities, than factors concerning health conditions. Highly stressogenic work and low tolerance of work burden as well as personal traits (age, frequent alcohol consumption among men and non-occupational burdens among women) represented risk factors responsible for low or moderate VAI values. The measurement of work ability index is an indirect assessment of workers' physical state, and it slightly depends on

Gender-related aspects in occupational allergies - Secondary publication and update.
Raulf, Monika; Brüning, Thomas; Jensen-Jarolim, Erika; van Kampen, Vera
2017-01-01
For years occupational allergies have been among the most frequently recorded occupational diseases, and both the skin as well as the respiratory tract may be affected. An estimated 9 to 15% of adult asthma is (partially) caused by work-related exposure. Gender-specific differences in exposure cause different risks in the workplace which affect the health of employees. This also applies to exposure and working conditions when handling sensitizing working substances. The presented gender-specific analysis of the German documentation of confirmed occupational respiratory allergic diseases and occupational skin diseases reveals clear differences between men and women in the number of diseases and also in exposure conditions and working areas.

Occupation-specific absenteeism costs associated with obesity and morbid obesity.
Cawley, John; Rizzo, John A; Haas, Kara
2007-12-01
To document the absenteeism costs associated with obesity and morbid obesity by occupation. Data from the Medical Expenditure Panel Survey for 2000-2004 are examined. The outcomes are probability of missing any work in the previous year and number of days of work missed in the previous year. Predictors include clinical weight classification, age, education, and race. Models are estimated separately by gender and occupation category. The probability of missing work in the past year, number of days missed, and costs of absenteeism rise with clinical weight classification for both women and men, and vary across occupation. Absenteeism costs associated with obesity total $4.3 billion annually in the United States. Substantial absenteeism costs are associated with obesity and morbid obesity. Employers should explore workplace interventions and health insurance expansions to reduce these costs.

How safe are federal regulations on occupational alcohol use?
Howland, Jonathan; Almeida, Alissa; Rohsenow, Damaris; Minsky, Sara; Greece, Jacey
2006-01-01
Current US federal regulations on occupational alcohol use for safety-sensitive jobs do not account for impairment from low doses of alcohol and next day effects of heavy drinking. Research on the effects of low doses of alcohol on neurocognitive and simulated occupational tasks suggests that the current per se level of these regulations is set too high. Research on the effects of heavy drinking on next-day neurocognitive and simulated occupational performance is mixed and suggests that further research is needed to determine the safety of current "bottle-to-throttle" times. Although low-dose and residual drinking effects may pose low relative risk for occupational error, the aggregate contribution of these exposures to workplace problems may be substantial, given the number of people exposed.

Occupational sunscreen use among US Hispanic outdoor workers.
Day, Ashley K; Stapleton, Jerod L; Natale-Pereira, Ana M; Goydos, James S; Coups, Elliot J
2015-10-17
Occupational ultraviolet radiation (UVR) exposure is a risk factor for skin cancer, and Hispanic individuals are over-represented in a number of outdoor occupations (e.g., farming, landscaping). This study examined predictors of occupational sunscreen use in a group of US Hispanic adults who work outdoors. A population-based sample of outdoor workers (n = 149, 85 % male) completed survey measures regarding their demographics, melanoma risk, perceived skin cancer risk, skin cancer knowledge, and their occupational sunscreen use. Sixty-nine percent of the sample reported never or rarely wearing sunscreen while working outdoors. Being female (p = .02), having a higher level of education (p = .03), and residing at a higher latitude (p = .04) were associated with more frequent sunscreen use. This study highlights the importance of interventions to promote sun protection behaviors among US Hispanic outdoor workers, and identifies potential intervention targets.

to verify whether there are associations among occupational roles, independence to perform Activities of Daily Living, purchasing power, and assistive technology for individuals with physical disabilities. 91 individuals with physical disabilities participated in the study. The instruments used were: Role Checklist, Brazilian Economic Classification Criterion, Barthel Index, and a Questionnaire to characterize the subjects. an association with a greater number of roles was found among more independent individuals using a lower number of technological devices. Higher purchasing power was associated with a lower functional status of dependence. even though technology was not directly associated with independence, the latter was associated with a greater number of occupational roles, which requires reflection upon independence issues when considering the participation in occupational roles. These findings support interdisciplinary actions designed to promote occupational roles in individuals with physical disabilities.

To analyze the evolving role, patterns of use, and costs of critical care medicine in the United States from 2000 to 2005. Retrospective study of data from the Hospital Cost Report Information System (Centers for Medicare and Medicaid Services, Baltimore, Maryland). Nonfederal, acute care hospitals with critical care medicine beds in the United States. None. None. We analyzed hospital and critical care medicine beds, bed types, days, occupancy rates, payer mix (Medicare and Medicaid), and costs. Critical care medicine costs were compared with national cost indexes. Between 2000 and 2005, the total number of U.S. hospitals with critical care medicine beds decreased by 12.2% (from 3,586 to 3,150). Although the number of hospital beds decreased by 4.2% (from 655,785 to 628,409), both hospital days and occupancy rates increased by 5.1% (from 145.1 to 152.5 million) and 13.7% (from 59% to 67%), respectively. Critical care medicine beds increased by 6.5% (from 88,252 to 93,955), days by 10.6% (from 21.0 to 23.2 million), and occupancy rates by 4.5% (from 65% to 68%). The majority (90%) of critical care medicine beds were classified as intensive care, premature/neonatal, and coronary care unit beds. The percentage of critical care medicine days used by Medicare decreased by 3.8% (from 37.9% to 36.5%) compared with an increase of 15.5% (from 14.5% to 16.8%) by Medicaid. From 2000 to 2005, critical care medicine costs per day increased by 30.4% (from $2698 to $3518). Although annual critical care medicine costs increased by 44.2% (from $56.6 to $81.7 billion), the proportion of hospital costs and national health expenditures allocated to critical care medicine decreased by 1.6% and 1.8%, respectively. However, the proportion of the gross domestic product used by critical care medicine increased by 13.7%. In 2005, critical care medicine costs represented 13.4% of hospital costs, 4.1% of national health expenditures, and 0.66% of the gross domestic product. Critical care

Occupational issues of adults with ADHD
2013-01-01
Background ADHD is a common neurodevelopmental disorder that persists into adulthood. Its symptoms cause impairments in a number of social domains, one of which is employment. We wish to produce a consensus statement on how ADHD affects employment. Methods This consensus development conference statement was developed as a result of a joint international meeting held in July 2010. The consensus committee was international in scope (United Kingdom, mainland Europe, United Arab Emirates) and consisted of individuals from a broad range of backgrounds (Psychiatry, Occupational Medicine, Health Economists, Disability Advisors). The objectives of the conference were to discuss some of the occupational impairments adults with ADHD may face and how to address these problems from an inclusive perspective. Furthermore the conference looked at influencing policy and decision making at a political level to address impaired occupational functioning in adults with ADHD and fears around employing people with disabilities in general. Results The consensus was that there were clear weaknesses in the current arrangements in the UK and internationally to address occupational difficulties. More so, Occupational Health was not wholly integrated and used as a means of making positive changes to the workplace, but rather as a superfluous last resort that employers tried to avoid. Furthermore the lack of cross professional collaboration on occupational functioning in adults with ADHD was a significant problem. Conclusions Future research needs to concentrate on further investigating occupational functioning in adults with ADHD and pilot exploratory initiatives and tools, leading to a better and more informed understanding of possible barriers to employment and potential schemes to put in place to address these problems.

Occupational therapy publications by Australian authors: A bibliometric analysis.
Brown, Ted; Gutman, Sharon A; Ho, Yuh-Shan
2018-01-18
Bibliometrics refers to the collection and measurement of publishing and citation data configurations with the goal of quantifying the influence of scholarly activities. Advantages of bibliometrics include the generation of quantitative indicators of impact, productivity, quality and collaboration. Those parties who benefit from the results of bibliometric analysis include researchers, educators, journal publishers, employers and research funding bodies. A bibliometric analysis was completed of peer-reviewed literature from 1991 to 2015, written by Australian occupational therapists (who were able to be identified as such), and indexed in the Science Citation Index-Expanded (SCI-Expanded) or the Social Sciences Citation Index (SSCI) databases. "Occupational therapy" and "occupational therapist(s)" were used as keywords to search journal articles' publication title, abstract, author details, keywords and KeyWord Plus. Between 1991 and 2015, 752 peer-reviewed journal articles were published by Australian occupational therapy authors. On average, those articles had 3.7 authors, 35 references, and were nine pages in length. The top four journals in which Australian occupational therapists published were Australian Occupational Therapy Journal, British Journal of Occupational Therapy, American Journal of Occupational Therapy, and Physical and Occupational Therapy in Paediatrics. The four Australian institutions that generated the largest number of occupational therapy articles were the University of Queensland, University of Sydney, La Trobe University, and Monash University. The top four countries with whom Australian authors collaborated in manuscript writing were the United Kingdom, United States, Canada and Sweden. The volume of occupational therapy peer-reviewed literature has grown over the last two decades. Australian authors have and continue to make significant contributions to the occupational therapy body of knowledge nationally and internationally. © 2018

Assessing bat detectability and occupancy with multiple automated echolocation detectors
Gorresen, P.M.; Miles, A.C.; Todd, C.M.; Bonaccorso, F.J.; Weller, T.J.
2008-01-01
Occupancy analysis and its ability to account for differential detection probabilities is important for studies in which detecting echolocation calls is used as a measure of bat occurrence and activity. We examined the feasibility of remotely acquiring bat encounter histories to estimate detection probability and occupancy. We used echolocation detectors coupled to digital recorders operating at a series of proximate sites on consecutive nights in 2 trial surveys for the Hawaiian hoary bat (Lasiurus cinereus semotus). Our results confirmed that the technique is readily amenable for use in occupancy analysis. We also conducted a simulation exercise to assess the effects of sampling effort on parameter estimation. The results indicated that the precision and bias of parameter estimation were often more influenced by the number of sites sampled than number of visits. Acceptable accuracy often was not attained until at least 15 sites or 15 visits were used to estimate detection probability and occupancy. The method has significant potential for use in monitoring trends in bat activity and in comparative studies of habitat use. ?? 2008 American Society of Mammalogists.

The percentage of bladder cancer as occupational disease in West-Europe is of 5/10%, but only a few amount of them are recognized as occupational disease from INAIL. The above mentioned research project is realized in order to decrease the gap between expected and claimed cases of occupational disease and it is conducted with the collaboration of ASL of Pisa, ASL of Empoli, Azienda Ospedaliera Universitaria Pisana and INAIL. 677 patients with bladder cancer were interviewed by phone, among them 64 subjects had a working experience compatible with neoplastic risks because had a previous occupational exposure to aromatic amines and metal working fluids. These cases were discussed into a Medical Staff and 40 cases were considered "probable" for occupational disease, 18 "possible", 3 cases are suspended for more research, 3 cases are considered "no professional disease". The research allows finding out a great number of bladder cancer, increasing the total amount of workers with occupational disease. The integrated approach with the collaboration among different institutions is surely the best way to allow and guarantee a suitable and right protection of workers with occupational disease.

Identifying occupational carcinogens: an update from the IARC Monographs.
Loomis, Dana; Guha, Neela; Hall, Amy L; Straif, Kurt
2018-05-16
The recognition of occupational carcinogens is important for primary prevention, compensation and surveillance of exposed workers, as well as identifying causes of cancer in the general population. This study updates previously published lists of known occupational carcinogens while providing additional information on cancer type, exposure scenarios and routes, and discussing trends in the identification of carcinogens over time. Data were extracted from International Agency for Research on Cancer (IARC) Monographs covering the years 1971-2017, using specific criteria to ensure occupational relevance and provide high confidence in the causality of observed exposure-disease associations. Selected agents were substances, mixtures or types of radiation classified in IARC Group 1 with 'sufficient evidence of carcinogenicity' in humans from studies of exposed workers and evidence of occupational exposure documented in the pertinent monograph. The number of known occupational carcinogens has increased over time: 47 agents were identified as known occupational carcinogens in 2017 compared with 28 in 2004. These estimates are conservative and likely underestimate the number of carcinogenic agents present in workplaces. Exposure to these agents causes a wide range of cancers; cancers of the lung and other respiratory sites, followed by skin, account for the largest proportion. The dominant routes of exposure are inhalation and dermal contact. Important progress has been made in identifying occupational carcinogens; nevertheless, there is an ongoing need for research on the causes of work-related cancer. Most workplace exposures have not been evaluated for their carcinogenic potential due to inadequate epidemiologic evidence and a paucity of quantitative exposure data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Sampling design trade-offs in occupancy studies with imperfect detection: examples and software
Bailey, L.L.; Hines, J.E.; Nichols, J.D.
2007-01-01
Researchers have used occupancy, or probability of occupancy, as a response or state variable in a variety of studies (e.g., habitat modeling), and occupancy is increasingly favored by numerous state, federal, and international agencies engaged in monitoring programs. Recent advances in estimation methods have emphasized that reliable inferences can be made from these types of studies if detection and occupancy probabilities are simultaneously estimated. The need for temporal replication at sampled sites to estimate detection probability creates a trade-off between spatial replication (number of sample sites distributed within the area of interest/inference) and temporal replication (number of repeated surveys at each site). Here, we discuss a suite of questions commonly encountered during the design phase of occupancy studies, and we describe software (program GENPRES) developed to allow investigators to easily explore design trade-offs focused on particularities of their study system and sampling limitations. We illustrate the utility of program GENPRES using an amphibian example from Greater Yellowstone National Park, USA.

Risk of injury for occupants of motor vehicle collisions from unbelted occupants.
MacLennan, P A; McGwin, G; Metzger, J; Moran, S G; Rue, L W
2004-12-01
Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. A population based cohort study. United States. MVC occupants (n = 152 191 unweighted, n = 18 426 684 weighted) seated between a belted or unbelted occupant and the line of the principal direction of force in frontal, lateral, and rear MVCs were sampled from the 1991-2002 National Automotive Sampling System General Estimates System. Offset MVCs were not included in the study. Risk ratios and 95% confidence intervals for injury (including death) for occupants seated contiguous to unbelted occupants compared to occupants seated contiguous to belted occupants. Risk ratios were adjusted for at risk occupant's sex, age, seating position, vehicle type, collision type, travel speed, crash severity, and at risk occupants' own seat belt use. Exposure to unbelted occupants was associated with a 40% increased risk of any injury. Belted at risk occupants were at a 90% increased risk of injury but unbelted occupants were not at increased risk. Risks were similar for non-incapacitating and capacitating injuries. There was a 4.8-fold increased risk of death for exposed belted occupants but no increased risk of death for unbelted occupants. Belted occupants are at an increased risk of injury and death in the event of a MVC from unbelted occupants.

We examined whether occupational and household tasks contributed to differences in pain between African Americans and whites with radiographic knee osteoarthritis (OA). Participants from the Johnston County Osteoarthritis Project self-reported the frequency (often/always vs never/seldom/sometimes) of performing 9 occupational tasks involving lower extremity joint loading at their longest job (N = 868) and current job (N = 273), as well as 8 household tasks ever performed (N = 811) and currently being performed (N = 767). The associations of the numbers of occupational or household tasks with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale were first examined in simple linear regression models. If significantly associated with greater pain, each of these was included in adjusted linear regression models to examine whether the association of race with pain remained statistically significant. African Americans reported significantly greater WOMAC pain scores than whites. Exposures to more occupational tasks at the longest job and the current job were associated with greater WOMAC pain scores (p < 0.01). The association of race with greater pain scores remained statistically significant when controlling for occupational tasks at the longest job, but was reduced by 26% and no longer significant when controlling for the number of current occupational tasks. Exposures to an increasing number of household tasks were associated with lower pain scores and were not further analyzed. Current performance of physically demanding occupational tasks contributed to racial differences in pain severity among individuals with knee OA. Better workplace policies to accommodate OA-related limitations may help to reduce racial differences in pain.

The study of human occupation requires a variety of methods to fully elucidate its complex, multifaceted nature. Although qualitative approaches have commonly been used within occupational therapy and occupational science, we contend that such qualitative research must extend beyond the sole use of interviews. Drawing on qualitative methodological literature, we discuss the limits of interview methods and outline other methods, particularly visual methods, as productive means to enhance qualitative research. We then provide an overview of our critical ethnographic study that used narrative, visual, and observational methods to explore the occupational transitions experienced by immigrants to Canada. We describe our use of occupational mapping and participatory occupation methods and the contributions of these combined methods. We conclude that adopting a variety of methods can enable a deeper understanding of the tacit nature of everyday occupation, and is key to advancing knowledge regarding occupation and to informing occupational therapy practice.

To investigate associations between respiratory disease and occupational exposures in a New Zealand urban population, the Wellington Respiratory Survey. Multiple regression analyses in a population sample of 1017 individuals aged 25 to 74 years with spirometry and questionnaire information, including a lifetime occupational history. Chronic bronchitis symptoms were associated with self-reported exposure to hairdressing, paint manufacturing, insecticides, welding, detergents and with ALOHA Job Exposure Matrix-assessed gases/fumes exposure. The strongest association was for hairdressing (odds ratio 6.91; 95% confidence interval: 2.02 to 23.70). Cumulative exposure to mineral dust and gases/fumes was associated with higher FEV₁% (forced expiratory volume in the first second of expiration) predicted. Analyses were limited by relatively small numbers of cases. Increased risks of objectively defined respiratory disease, which have been previously documented, were not seen. Nevertheless, the study suggested increased risk of respiratory symptoms with various occupational exposures as well as likely healthy worker effect.

Occupation and chronic obstructive pulmonary disease (COPD).
Cullinan, Paul
2012-01-01
There is growing interest in preventable, non-smoking causes of chronic obstructive pulmonary disease (COPD), among which are chronic exposures to respiratory irritants in the workplace. Reviews of occupational COPD in specific occupations and industries and in general populations; supplemented with other or more recently published material. There is good evidence for an increased risk of COPD from certain specific exposures (coal mine dust, silica, welding fume, textile dust, agricultural dust, cadmium fume). Less clear is the causal role of non-specific dusts or fumes/gases in general populations where the available literature is notably uncritical. Other specific exposures, such as diesel fume; interactions between specific exposures and cigarette smoking; the development of safe working limits. Occupations with large numbers of exposed employees, particularly in low-income countries.

Activating occupational safety and health activities among Small- and Medium-scale Enterprises (SMEs) is a major issue because more than 80% of Japanese workers belong to these enterprises, in which the number of workers are less than 300 people. However, as the size of the enterprise decreases, the occurrence of problems of safety and health management systems and safety and health activities increases. Reasons for this include both the limitations of investments shortages of human resources. Occupational health services in SMEs has been provided by the cooperation of the following institutions: public associations (such as Regional Occupational Health Centers, Occupational Health Promotion Centers, Japan Industrial Safety and Health Association (JISHA)), occupational health agencies which provide checkup services, health insurance associations, and regional medical services. In contrast to the low coverage of occupational health services among SMEs in Japan, there are some countries in Europe in which this coverage is almost 100%. This is because of the development of occupational health services outside the company. To show the benefits of the safety and health activities to managers of SMEs, and to motivate them to take advantage of the services, it is important to consider measurements. Also, establishing systems that provide those services, improving the quality of specialists such as occupational physicians, and educating human resources, are all necessary.

Occupational disease among non-governmental employees in Malaysia: 2002-2006.
Abas, Adinegara Bin Lutfi; Said, Abdul Razzak Bin Mohd; Mohammed, Mohammed Azman Bin Aziz; Sathiakumar, Nalini
2008-01-01
In the absence of systematic occupational disease surveillance, other data collected by governmental agencies or industry is useful in the identification of occupational diseases and their control. We examined data on occupational diseases reported by non-governmental employees to the national workers' social security organization in Malaysia, 2002-2006. The overall incidence rate of occupational disease was 2.8 per 100,000 workers. There was an increase in the annual number and rates of occupational disease over time. The most frequently reported conditions were hearing impairment (32%) and musculoskeletal disorders (28%). Workers in the non-metallic manufacturing industry had the highest average incidence rate of hearing impairment (12.7 per 100,000 workers) and musculoskeletal disorders (3.5 per 100,000 workers), compared to all other industries. Preventive measures should focus on safety education, engineering control and workplace ergonomics. Enforcing workplace standards and incorporating an ongoing surveillance system will facilitate the control and reduction of occupational disease.

Immigration and its impact on daily occupations: a scoping review.
Bennett, Kayla Marie; Scornaiencki, Jennifer Marie; Brzozowski, Jennifer; Denis, Suzanne; Magalhaes, Lilian
2012-12-01
Immigrants often adopt new and unfamiliar occupations in an attempt to adapt to their new culture. Occupations provide a means for participation in the host country and play a significant role in formulating a person's identity. This scoping review sought to identify the current knowledge on immigration and its impact on occupations. A scoping review for peer-reviewed articles published between 2000 and 2010 in English or French was completed. Thirty-six articles met the inclusion criteria. Four themes were identified: 1) role change; 2) work; 3) identity; and 4) health and well-being. Limitations include the lack of a consistent definition of occupation, research primarily being conducted in the North American context and the limited number of occupational therapy based articles. Future research should focus on a systematic review of the lived experiences of immigrants and their occupational contexts, and how this can inform policy development.

2005-01-01
To describe disease development and occupational therapy during the first 10 years of rheumatoid arthritis (RA), and to assess patients' experiences of occupational therapy and comprehensive care. A total of 168 early RA patients with variable disease severity were followed up with regular team visits. The occupational therapist evaluated hand function and activity and performed the necessary interventions. These were recorded and the number of visits generating interventions was calculated. Semi-structured interview of 11 patients regarding their views of occupational therapy and team contact was performed. Impairments of hand function were in general mild to moderate and remained fairly unchanged over time. Activity limitations increased slowly. Half of the follow-up visits generated interventions. Most common were prescriptions of assistive devices and orthoses, hand-training instructions and patient education. The patients interviewed were positive regarding occupational therapy and felt safe with comprehensive care. RA patients in all stages of the disease benefit from regular contact with an occupational therapist and team care.

Risk of injury for occupants of motor vehicle collisions from unbelted occupants
MacLennan, P; McGwin, G; Metzger, J; Moran, S; Rue, L
2004-01-01
Objective: Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. Design: A population based cohort study. Setting: United States. Subjects: MVC occupants (n = 152 191 unweighted, n = 18 426 684 weighted) seated between a belted or unbelted occupant and the line of the principal direction of force in frontal, lateral, and rear MVCs were sampled from the 1991–2002 National Automotive Sampling System General Estimates System. Offset MVCs were not included in the study. Main outcome measure: Risk ratios and 95% confidence intervals for injury (including death) for occupants seated contiguous to unbelted occupants compared to occupants seated contiguous to belted occupants. Risk ratios were adjusted for at risk occupant's sex, age, seating position, vehicle type, collision type, travel speed, crash severity, and at risk occupants' own seat belt use. Results: Exposure to unbelted occupants was associated with a 40% increased risk of any injury. Belted at risk occupants were at a 90% increased risk of injury but unbelted occupants were not at increased risk. Risks were similar for non-incapacitating and capacitating injuries. There was a 4.8-fold increased risk of death for exposed belted occupants but no increased risk of death for unbelted occupants. Conclusions: Belted occupants are at an increased risk of injury and death in the event of a MVC from unbelted occupants. PMID:15583258

Inference for occupancy and occupancy dynamics
O'Connell, Allan F.; Bailey, Larissa L.; O'Connell, Allan F.; Nichols, James D.; Karanth, K. Ullas
2011-01-01
This chapter deals with the estimation of occupancy as a state variable to assess the status of, and track changes in, species distributions when sampling with camera traps. Much of the recent interest in occupancy estimation and modeling originated from the models developed by MacKenzie et al. (2002, 2003), although similar methods were developed independently (Azuma et al. 1990; Bayley and Petersen 2001; Nichols and Karanth, 2002; Tyre et al. 2003), all of which deal with species occurrence information and imperfect detection. Less than a decade after these publications, the modeling and estimation of species occurrence and occupancy dynamics have increased significantly. Special features of scientific journals have explored innovative uses of detection–nondetection data with occupancy models (Vojta 2005), and an entire volume has synthesized the use and application of occupancy estimation methods (MacKenzie et al. 2006). Reviews of the topical concepts, philosophical considerations, and various sampling designs that can be used for occupancy estimation are now readily available for a range of audiences (MacKenzie and Royle 2005; MacKenzie et al. 2006; Bailey et al. 2007; Royle and Dorazio 2008; Conroy and Carroll 2009; Kendall and White 2009; Hines et al. 2010; Link and Barker 2010). As a result, it would be pointless here to recast all that these publications have so eloquently articulated, but that said, a review of any scientific topic requires sufficient context and relevant background information, especially when relatively new methodologies and techniques such as occupancy estimation and camera traps are involved. This is especially critical in a digital age where new information is published at warp speed, making it increasingly difficult to stay abreast of theoretical advances and research developments.

Medium-density fibreboard and occupational asthma. A case series.
Burton, C; Bradshaw, L; Agius, R; Burge, S; Huggins, V; Fishwick, D
2011-08-01
Medium-density fibreboard (MDF) is a wood composite material, composed primarily of softwood, bonded with a synthetic formaldehyde-based resin. It is increasingly used, as it has various advantages over natural woods. Enquiry of the national reporting scheme data and three case reports were used to further the evidence base linking this exposure to occupational asthma (OA). From 1991 to 2007, 21 cases of occupational sensitization to MDF were reported to the UK voluntary reporting scheme, Surveillance of Work Related Occupational Respiratory Disease (SWORD): 18 reported as occupational asthma (OA) and 3 as occupational rhinitis. All workers were male, with a mean age of 48 years, working in education, furniture manufacturing or joinery among other employments. Whilst reporting scheme data identified relatively small numbers of cases of OA likely to be due to MDF, the evidence base supporting this link is generally lacking. The three cases presented, where OA was attributed to MDF exposure, add to this evidence.

The progression of occupational science in Chile is documented in the main scientific publication of the field, the Chilean Journal of Occupational Therapy (RChTO). Identify approaches to understanding and applying occupation and occupational science as elucidated in the RChTO. A systematic qualitative review of the journal (2001-2012) identified articles elucidating an approach to understanding and application operationally defined as references to specific authors, theories, models/paradigms, definitions, and other fields that support approaches to O/OS. The study identified two main approaches. The first considers occupation/occupational science from a practical perspective or as a means to explain human behavior; the second considers occupation/occupational science as an object of study. Each approach is further divided into categories. This study provides a novel perspective on regional use of occupational science concepts. These findings contribute to our understanding of this science in context and to recognition of the cultural relevance of these scientific concepts.

2010-03-01
The year 2009 led to a number of significant advances in environmental and occupational allergic diseases. The role of exposure to environmental pollutants, respiratory viruses, and allergen exposure showed significant advances. New allergens were identified. Occupational asthma and the relationship of complementary and alternative medicine to allergic diseases were extensively reviewed. New approaches to immunotherapy, novel vaccine techniques, and methods to reduce risks for severe allergic disease were addressed.

Work-related musculoskeletal disorders are a significant burden; however, no consensus has been reached on how to maximize occupational rehabilitation programs for people with these disorders, and the impact of simulating work tasks as a mode of intervention has not been well examined. In this retrospective cohort study, the authors used logistic regression to identify client and program factors predicting success for 95 clients in a general occupational rehabilitation program and 71 clients in a comprehensive occupational rehabilitation program. The final predictive model for general rehabilitation included gender, number of sessions completed, and performance of work simulation activities. Maximum hours per session was the only significant predictor of success in the comprehensive rehabilitation program. This study identifies new factors associated with success in occupational rehabilitation, specifically highlighting the importance of intensity (i.e., session length and number of sessions) of therapy and occupation-based activities for this population.

Sampling scales define occupancy and underlying occupancy-abundance relationships in animals.
Steenweg, Robin; Hebblewhite, Mark; Whittington, Jesse; Lukacs, Paul; McKelvey, Kevin
2018-01-01
Occupancy-abundance (OA) relationships are a foundational ecological phenomenon and field of study, and occupancy models are increasingly used to track population trends and understand ecological interactions. However, these two fields of ecological inquiry remain largely isolated, despite growing appreciation of the importance of integration. For example, using occupancy models to infer trends in abundance is predicated on positive OA relationships. Many occupancy studies collect data that violate geographical closure assumptions due to the choice of sampling scales and application to mobile organisms, which may change how occupancy and abundance are related. Little research, however, has explored how different occupancy sampling designs affect OA relationships. We develop a conceptual framework for understanding how sampling scales affect the definition of occupancy for mobile organisms, which drives OA relationships. We explore how spatial and temporal sampling scales, and the choice of sampling unit (areal vs. point sampling), affect OA relationships. We develop predictions using simulations, and test them using empirical occupancy data from remote cameras on 11 medium-large mammals. Surprisingly, our simulations demonstrate that when using point sampling, OA relationships are unaffected by spatial sampling grain (i.e., cell size). In contrast, when using areal sampling (e.g., species atlas data), OA relationships are affected by spatial grain. Furthermore, OA relationships are also affected by temporal sampling scales, where the curvature of the OA relationship increases with temporal sampling duration. Our empirical results support these predictions, showing that at any given abundance, the spatial grain of point sampling does not affect occupancy estimates, but longer surveys do increase occupancy estimates. For rare species (low occupancy), estimates of occupancy will quickly increase with longer surveys, even while abundance remains constant. Our results

Objective To identify efficient PubMed search strategies to retrieve articles regarding putative occupational determinants of conditions not generally considered to be work related. Methods Based on MeSH definitions and expert knowledge, we selected as candidate search terms the four MeSH terms describing ‘occupational disease’, ‘occupational exposure’, ‘occupational health’ and ‘occupational medicine’ (DEHM) alongside 22 other promising terms. We first explored overlaps between the candidate terms in PubMed. Using random samples of abstracts retrieved by each term, we estimated the proportions of articles containing potentially pertinent information regarding occupational aetiology in order to formulate two search strategies (one more ‘specific’, one more ‘sensitive’). We applied these strategies to retrieve information on the possible occupational aetiology of meningioma, pancreatitis and atrial fibrillation. Results Only 20.3% of abstracts were retrieved by more than one DEHM term. The more ‘specific’ search string was based on the combination of terms that yielded the highest proportion (40%) of potentially pertinent abstracts. The more ‘sensitive’ string was based on the use of broader search fields and additional coverage provided by other search terms under study. Using the specific string, the numbers of abstracts needed to read to find one potentially pertinent article were 1.2 for meningioma, 1.9 for pancreatitis and 1.8 for atrial fibrillation. Using the sensitive strategy, the numbers needed to read were 4.4 for meningioma, 8.9 for pancreatitis and 10.5 for atrial fibrillation. Conclusions The proposed strings could help health care professionals explore putative occupational aetiology for diseases that are not generally thought to be work related. PMID:19819858

[Lung Cancer as an Occupational Disease].
Baur, X; Woitowitz, H-J
2016-08-01
Lung cancer is one of the most frequently encountered cancer types. According to the latest WHO data, about 10 % of this disease are due to occupational exposure to cancerogens. Asbestos is still the number one carcinogen. Further frequent causes include quarz and ionizing radiation (uranium mining). Probable causes of the disease can be identified only with the help of detailed occupational history taken by a medical specialist and qualified exposure assessment. Without clarifying the cause of the disease, there is neither a correct insurance procedure nor compensation for the victim, and furthermore, required preventive measures cannot be initiated. © Georg Thieme Verlag KG Stuttgart · New York.

A questionnaire assessing various aspects of paid as well as unpaid forms of productive activity was mailed to stratified samples of male and female white collar workers, approximately matched for educational and occupational level. Data from 501 men and 679 women employed full time revealed traditional gender differences in terms of main responsibility for household duties, child care etc. In keeping with this, women reported higher levels of work overload, stress and conflict than men, which increased significantly with the number of children at home. The various stress indices reached a peak between the ages of 35 and 39. Men reported more autonomy in their paid work whereas women reported more control at home. Men and women at the upper managerial levels reported more control over their total work situation and less conflict between demands.

Mines are hazardous and workers can suffer many types of accidents caused by fire, flood, explosion or collapse. Injury incidence rates in mining are considerably higher than those registered by other economic sectors. One of the main reasons for this high-level incidence rate is the existence of a large number of dangerous workplaces. This work analyzes the influence that occupational safety management had on the accidents that took place in Spanish mining of industrial and ornamental stone during the period 2007-2008. Primary data sources are: (a) Results from a statistical study of the occupational health and safety management practices of 71 quarries defined by a questionnaire of 41 items; and (b) Occupational accidents registered in the Spanish industrial and ornamental stone mining throughout the period 2007-2008. The obtained results indicate that workplaces with a low average score in the analysis of occupational safety management have a higher incidence rate of accidents. Studies on mining workplaces are very important to help detect occupational safety concerns. Results from this study help raise awareness and will encourage the adoption of appropriate measures to improve safety.

Occupational exposure associated with reproductive dysfunction.
Kumar, Sunil
2004-01-01
Evidence suggestive of harmful effects of occupational exposure on the reproductive system and related outcomes has gradually accumulated in recent decades, and is further compounded by persistent environmental endocrine disruptive chemicals. These chemicals have been found to interfere with the function of the endocrine system, which is responsible for growth, sexual development and many other essential physiological functions. A number of occupations are being reported to be associated with reproductive dysfunction in males as well as in females. Generally, occupations involving the manufacture/or application of some of the persistent chemicals that are not easily degradable as well as bio-accumulative chemicals, occupations involving intensive exposure to heat and radiation, occupations involving the use of toxic solvents as well as toxic fumes are reported to be associated with reproductive dysfunction. Occupational exposure of males to various persistent chemicals have been reported to have male mediated adverse reproductive outcomes in the form of abortion, reduction in fertility etc. with inconclusive or limited evidence. Nevertheless, there is a need for more well designed studies in order to implicate any individual chemical having such effects as in most occupations workers are exposed to raw, intermediate and finished products and there are also several confounding factors associated with lifestyles responsible for reproductive dysfunction. There is an urgent need to look at indiscriminate use of persistent chemicals especially pesticides and persistent organic pollutants (POP's) as these chemicals enter the food chain also and could be potential for exposure during the critical period of development. It is also necessary to impart information, and to educate about the safe use of these chemicals, as a very sensitive reproduction issue is involved with exposure to these chemicals. Occupational exposures often are higher than environmental exposures, so

[Occupational factors influencing lung cancer in women in epidemiological studies].
Swiatkowska, Beata
2011-01-01
Lung cancer is the most common cancer in men, although the alarming statistics of recent years indicate that this pathology affects also more likely a group of women and in recent years has become the leading cause of cancer deaths among Polish women. This article presents the main issues relating to occupational determinants of lung cancer in women. The results of the analysis show that the number of neoplastic diseases, including the lung cancer, recognized as an occupational disease in Poland is low, particularly among women. A major factor hampering the certification of occupational etiology of lung cancer is a long latency period, no differences in terms of the clinical and morphological characteristics from lung cancer occurring in the general population, and relatively small number of identified occupational carcinogens. Analysis of the available literature on the adverse workplace conditions shows that only a few epidemiological studies focus on the problem of job-related risk among women, and only some of them provide detailed results for lung cancer. Moreover, the abundant literature on the subject concerning the male workers might not be fully relevant because of possible differences in hormonal, genetic and other gender-related biological differences that may significantly modify the risk of cancer in women. These aspects cause that the true contribution of occupational factors to the risk of lung cancer, particularly in women, is underestimated.

Occupational contact dermatitis in the UK: a surveillance report from EPIDERM and OPRA.
Meyer, J D; Chen, Y; Holt, D L; Beck, M H; Cherry, N M
2000-05-01
Since February 1993 the EPIDERM surveillance scheme has collected data on occupational skin disease from consultant dermatologists in the UK. Reporting by occupational physicians to the scheme began in May 1994 and was superseded in January 1996 by the Occupational Physicians Reporting Activity (OPRA). The schemes currently receive reports on incident cases from 244 dermatologists and 790 occupational physicians. An estimated total of 9937 cases of contact dermatitis reported by dermatologists was calculated from surveillance data; 8129 contact dermatitis cases were estimated from reports by occupational physicians. The annual incidence of occupational contact dermatitis from dermatologist reports was 6.4 cases per 100,000 workers and 6.5 per 100,000 from reports by occupational physicians, an overall rate of 12.9 cases per 100,000 workers. Manufacturing industries account for the greatest number of cases seen by both sets of reporting physicians, with health care employment second. Reports from dermatologists also indicate high rates of dermatitis in the personal service industries (mainly hairdressers and barbers) and in agriculture. With the exception of an increase in cases seen in nurses in both schemes, the numbers and proportions of cases of contact dermatitis within occupations have remained fairly constant over the 6-year reporting period. Agents accounting for the highest number of allergic contact dermatitis cases were rubber (23.4% of allergic cases reported by dermatologists), nickel (18.2), epoxies and other resins (15.6), aromatic amines (8.6), chromium and chromates (8.1), fragrances and cosmetics (8.0), and preservatives (7.3). Soaps (22.0% of cases), wet work (19.8), petroleum products (8.7), solvents (8.0), and cutting oils and coolants (7.8) were the most frequently cited agents in cases of irritant dermatitis. The national scope of the data, together with the parallel structure by which both dermatologists and occupational physicians report

Are female healthcare workers at higher risk of occupational injury?
Alamgir, Hasanat; Yu, Shicheng; Drebit, Sharla; Fast, Catherine; Kidd, Catherine
2009-05-01
Differential risks of occupational injuries by gender have been examined across various industries. With the number of employees in healthcare rising and an overwhelming proportion of this workforce being female, it is important to address this issue in this growing sector. To determine whether compensated work-related injuries among females are higher than their male colleagues in the British Columbia healthcare sector. Incidents of occupational injury resulting in compensated days lost from work over a 1-year period for all healthcare workers were extracted from a standardized operational database and the numbers of productive hours were obtained from payroll data. Injuries were grouped into all injuries and musculoskeletal injuries (MSIs). Detailed analysis was conducted using Poisson regression modelling. A total of 42 332 employees were included in the study of whom 11% were male and 89% female. When adjusted for age, occupation, sub-sector, employment category, health region and facility, female workers had significantly higher risk of all injuries [rate ratio (95% CI) = 1.58 (1.24-2.01)] and MSIs [1.43 (1.11-1.85)] compared to their male colleagues. Occupational health and safety initiatives should be gender sensitive and developed accordingly.

Nowadays, journalism is considered a stressful occupation, not only due to the stress perceived in journalists' daily work but also due to the critical, potentially traumatic events they report. However, research on journalists' occupational stress in both these professional settings is still scarce. This study aims to characterize and compare occupational stress variables perceived by journalists in their daily work and in critical scenarios. Taking the Holistic Model of Occupational Stress by Nelson and Simmons (2003) as a framework, 25 Portuguese journalists, all with experience in reporting critical events, were interviewed on their perceptions of some core variables of the model: occupational stressors, distress and eustress emotional reactions, and the consequences of these experiences on their well-being. Differences among these core variables, according to the number of deployments to a critical event, were statistically analysed in order to ascertain whether repeated exposure to trauma influenced journalists' occupational stress perceptions. The data content analysis showed that occupational stressors and emotional reactions differed across settings, while the consequences associated with journalists' experiences were perceived as being mainly negative in both occupational contexts. Significant differences were identified in some of these variables according to the number of deployments to a critical event (p < .05). These findings may contribute to a reflection on the role of media organizations in preparing and supporting journalists in their work performance, and on the promotion of occupational health within the scope of journalists' daily work and critical events. The article closes with considerations for future studies.

Background The progression of occupational science in Chile is documented in the main scientific publication of the field, the Chilean Journal of Occupational Therapy (RChTO). Objective Identify approaches to understanding and applying occupation and occupational science as elucidated in the RChTO. Methodology A systematic qualitative review of the journal (2001–2012) identified articles elucidating an approach to understanding and application operationally defined as references to specific authors, theories, models/paradigms, definitions, and other fields that support approaches to O/OS. Results The study identified two main approaches. The first considers occupation/occupational science from a practical perspective or as a means to explain human behavior; the second considers occupation/occupational science as an object of study. Each approach is further divided into categories. Conclusion This study provides a novel perspective on regional use of occupational science concepts. These findings contribute to our understanding of this science in context and to recognition of the cultural relevance of these scientific concepts. PMID:29097971

The values of occupational therapy: Perceptions of occupational therapists in Quebec.
Drolet, Marie-Josée; Désormeaux-Moreau, Marjorie
2016-07-01
Recently, there has been increasing interest in the values of occupational therapy and the values held by occupational therapists. A wide range of values has been reported in the literature. Furthermore, despite the fact that values are an important part of professional identity, empirical studies have demonstrated that several occupational therapists possess an ambiguous professional identity. This study was undertaken to explore the values of Canadian occupational therapists, specifically French-speaking occupational therapists in Quebec. Semi-structured interviews were conducted with 26 occupational therapists. Their narratives were subject to hermeneutic analysis, a method of textual analysis common in philosophical research. A total of 16 values were identified in the discourses of the occupational therapists interviewed: autonomy; human dignity; occupational participation; social justice and equity; professionalism; holism; partnership, environment, or ecological approach; quality of life; solicitude; honesty; integrity; health; creativity; professional autonomy; effectiveness; and spirituality. The results of this study are, in general, consistent with those reported in the few other empirical studies that have documented the values perceptions of occupational therapists. Finally, the explanation of the values of occupational therapists may reinforce their professional identity and favour best, or at least desirable, professional practices related to ethics and culture.

[Amendments of occupational laws in Germany and consequences for occupational health].
Bolm-Audorff, U
2008-03-01
German legislation with respect to occupational health during recent years is reviewed. Discussed is the occupational safety law and related legislation as the hazardous substances act and the biological hazard act, the occupational health and safety act and the social act VII. Most improvements of occupational standards in Germany are induced by regulations of the European Union. Furthermore initiatives of the federal government and the federal states according to an amendment of the social act VII and the occupational health and safety act, which would induce a reduction of social standards, are discussed. The role of occupational medicine in companies by some of the above mentioned laws is improved. On the other hand the situation of occupational physicians in companies, universities and other agencies is characterized by budget cuts, reduction of occupational standards and loss of importance.

Extreme cold and heat have been linked to an increased risk of occupational injuries. However, the evidence is still limited to a small number of studies of people with relatively few injuries and with a limited geographic extent, and the corresponding economic effect has not been studied in detail. We assessed the relationship between ambient temperatures and occupational injuries in Spain along with its economic effect. The daily number of occupational injuries that caused at least one day of leave and the daily maximum temperature were obtained for each Spanish province for the years 1994-2013. We estimated temperature-injuries associations with distributed lag nonlinear models, and then pooled the results using a multivariate meta-regression model. We calculated the number of injuries attributable to cold and heat, the corresponding workdays lost, and the resulting economic effect. The study included 15,992,310 occupational injuries. Overall, 2.72% [95% confidence interval (CI): 2.44-2.97] of all occupational injuries were attributed to nonoptimal ambient temperatures, with moderate heat accounting for the highest fraction. This finding corresponds to an estimated 0.67 million (95% CI: 0.60-0.73) person-days of work lost every year in Spain due to temperature, or an annual average of 42 d per 1,000 workers. The estimated annual economic burden is €370 million, or 0.03% of Spain's GDP (€2,015). Our findings suggest that extreme ambient temperatures increased the risk of occupational injuries, with substantial estimated health and economic costs. These results call for public health interventions to protect workers in the context of climate change. https://doi.org/10.1289/EHP2590.

Listing Occupational Carcinogens
Siemiatycki, Jack; Richardson, Lesley; Straif, Kurt; Latreille, Benoit; Lakhani, Ramzan; Campbell, Sally; Rousseau, Marie-Claude; Boffetta, Paolo
2004-01-01
The occupational environment has been a most fruitful one for investigating the etiology of human cancer. Many recognized human carcinogens are occupational carcinogens. There is a large volume of epidemiologic and experimental data concerning cancer risks in different work environments. It is important to synthesize this information for both scientific and public health purposes. Various organizations and individuals have published lists of occupational carcinogens. However, such lists have been limited by unclear criteria for which recognized carcinogens should be considered occupational carcinogens, and by inconsistent and incomplete information on the occupations and industries in which the carcinogenic substances may be found and on their target sites of cancer. Based largely on the evaluations published by the International Agency for Research on Cancer, and augmented with additional information, the present article represents an attempt to summarize, in tabular form, current knowledge on occupational carcinogens, the occupations and industries in which they are found, and their target organs. We have considered 28 agents as definite occupational carcinogens, 27 agents as probable occupational carcinogens, and 113 agents as possible occupational carcinogens. These tables should be useful for regulatory or preventive purposes and for scientific purposes in research priority setting and in understanding carcinogenesis. PMID:15531427

Crash pulse optimization for occupant protection at various impact velocities.
Ito, Daisuke; Yokoi, Yusuke; Mizuno, Koji
2015-01-01
Vehicle deceleration has a large influence on occupant kinematic behavior and injury risks in crashes, and the optimization of the vehicle crash pulse that mitigates occupant loadings has been the subject of substantial research. These optimization research efforts focused on only high-velocity impact in regulatory or new car assessment programs though vehicle collisions occur over a wide range of velocities. In this study, the vehicle crash pulse was optimized for various velocities with a genetic algorithm. Vehicle deceleration was optimized in a full-frontal rigid barrier crash with a simple spring-mass model that represents the vehicle-occupant interaction and a Hybrid III 50th percentile male multibody model. To examine whether the vehicle crash pulse optimized at the high impact velocity is useful for reducing occupant loading at all impact velocities less than the optimized velocity, the occupant deceleration was calculated at various velocities for the optimized crash pulse determined at a high speed. The optimized vehicle deceleration-deformation characteristics that are effective for various velocities were investigated with 2 approaches. The optimized vehicle crash pulse at a single impact velocity consists of a high initial impulse followed by zero deceleration and then constant deceleration in the final stage. The vehicle deceleration optimized with the Hybrid III model was comparable to that determined from the spring-mass model. The optimized vehicle deceleration-deformation characteristics determined at a high speed did not necessarily lead to an occupant deceleration reduction at a lower velocity. The maximum occupant deceleration at each velocity was normalized by the maximum deceleration determined in the single impact velocity optimization. The resulting vehicle deceleration-deformation characteristic was a square crash pulse. The objective function was defined as the number of injuries, which was the product of the number of collisions at the

We investigated the working behavior of part-time occupational physicians using practical recording sheets to clarify issues of occupational physicians' activities according to industrial groups or size of business. We collected 561 recording sheets in 96 industries from 11 part-time occupational physicians as collaborators, who volunteered to be a part of this research. We collected a variety of information from the practical recording sheets, including the industry in which each occupational physician was employed, the annual number of times of work attendance, occupational physician-conducted workplace patrol, and employee health management. We investigated their annual practices regarding work environment management, work management, health management, and general occupational health management. In addition, we analyzed the differences between the secondary and tertiary industry groups and between the group of offices employing 100 people or fewer (≤100 group) and 101 people and above (≥101 group) in each industry group. The median work attendance by all occupational physicians was four times a year; the tertiary industry group had a significantly lower rate of work attendance than the secondary industry group. The occupational physicians' participation in risk assessment, mental health measures or overwork prevention, and the formulation of the occupational health management system and the annual plan were significantly lower in the tertiary industry group than in the secondary industry group. We observed that for the annual number of times of work attendance, occupational physician-conducted workplace patrol was significantly lower in the ≤100 group than in the ≥101 group in each industry group. These findings show that occupational physicians' activities have not been conducted enough in tertiary industries and small-sized offices employing ≤100 people. It would be necessary to evaluate how to provide occupational health service or appropriate

Clarifying the Construct of Occupational Engagement for Occupational Therapy Practice.
Kennedy, Jennifer; Davis, Jane A
2017-04-01
Occupational engagement (OE) has been presented as a core construct in occupational therapy; however, its broad conceptualization and confounding definitions are problematic. Clarifying the construct of OE would help occupational therapists to explicate the nature of their practice. The purpose of this study was to explore occupational therapists' perspectives of the construct of OE. Qualitative descriptive methodology was used to collect data using semistructured interviews with nine practicing occupational therapists in the Greater Toronto Area. Qualitative content analysis, using an inductive approach, was employed to uncover emerging categories. Participants spoke about transitioning from therapeutic engagement to OE with a client by following a client's path of choice. The essential elements and influencers of OE were highlighted, and the relationship between OE and occupational performance was discussed. The findings provide an initial understanding of essential elements necessary to enable clients to initiate engagement in therapy and then, subsequently, in occupations of their choice.

Issues in bidding for contracts for occupational therapy services.
Harms, S; Law, M
2001-06-01
There is an increasing number of occupational therapists in Canada who are involved in bidding for contracts to deliver occupational therapy services. Occupational therapists working in an institutional or community-based setting may not have had the responsibility of developing a proposal or a marketing plan for bidding purposes. However, the responsibility of developing a bid to compete for a service delivery contract often rests on occupational therapists who are sole practitioners in a private practice setting. The purpose of this paper is to highlight issues in the literature such as service delivery plans, marketing strategies and costing of services that can assist the occupational therapist in the development of a contractual bid. A specific clinical example, school therapy services, has been used to illustrate how these strategies can be applied to practice. Success in contractual bids appears to be primarily influenced by cost of the service, the expertise of the service provider, ability to provide coordinated care, ease of access for clients, and inclusion of methods to measure client outcome.

In a previous study consensus was sought from Malaysian occupational therapists of occupation-based intervention (OBI) that was perceived as a means and an end. Occupation as a means refers to occupational and purposeful tasks as a therapeutic agent while occupation as an end refers to occupation as an outcome of intervention. The purpose of this follow-up study was to describe the occupational therapists' experiences of providing OBI in hand injury rehabilitation in Malaysia. Sixteen occupational therapists with more than five years of experience in hand rehabilitation were individually interviewed on their experiences of using OBI in practice. Data were thematically analysed using interpretative phenomenological analysis. Definition of "Occupation as a means", and "Occupation as an end" was broadened after data analysis of interviews to include two new themes: "Rewarding yet challenging" and "Making OBI a reality". Occupational therapists had positive experiences with OBI and perceived that occupation as a means and an end can be merged into a single therapy session when the occupational therapists use an occupation that is therapeutic. Although occupation as a means and as an end have different purposes, when the ultimate goal is to enhance the clients' maximum level of functioning both can be used for successful rehabilitation of hand injuries.

Occupational injuries due to violence.
Hales, T; Seligman, P J; Newman, S C; Timbrook, C L
1988-06-01
Each year in the United States, an estimated 800 to 1,400 people are murdered at work, and an unknown number of nonfatal injuries due to workplace violence occur. Based on Ohio's workers' compensation claims from 1983 through 1985, police officers, gasoline service station employees, employees of the real estate industry, and hotel/motel employees were found to be at the highest risk for occupational violent crime (OVC) injury and death. Grocery store employees, specifically those working in convenience food stores, and employees of the real estate industry had the most reported rapes. Four previously unidentified industries at increased risk of employee victimization were described. Identification of industries and occupations at high risk for crime victimization provides the opportunity to focus preventive strategies to promote employee safety and security in the workplace.

To investigate the characteristics of 136 patients with occupational diseases, to summarize key techniques used in field investigation, and to provide a scientific basis for the development of standard operating procedures for field investigation of occupational disease diagnosis. Field investigation and routine data analysis were performed to analyze the cases diagnosed by Guangdong Provincial Hospital for Occupational Disease Prevention and Treatment from January 2009 to December 2014. A total of 136 cases of occupational diseases were diagnosed by Guangdong Provincial Hospital for Occupational Disease Prevention and Treatment from 2009 to 2014, and there were 66 cases of leukemia, 18 cases of suspected occupational benzene poisoning, 12 cases of suspected occupational handarm vibration disease, and 11 cases of suspected pneumoconiosis. Of all these patients, 41.91% were engaged in at least three types of work, 70.59% were exposed to at least three types of chemicals, 25.74% experienced changes in technical processes and chemicals, and 47.06% had disputes on the chemicals they were exposed to during verification by both parties. Occupational hazard factors were detected. Most samples (358)were used to measure benzene concentration in workplace air, among which 11.7% had a benzene concentration of >6.00 mg/m(3)(exceeding standard), 13.41% had a benzene concentration of 3.26~6.00 mg/m(3), 75.42% had a benzene concentration of<0.03 to <3.25 mg/m(3). The samples of suspected occupational hand-arm vibration disease, suspected pneumoconiosis, and suspected occupational noiseinduced hearing loss had high overstandard rates (100%, 93.8%, and 83.3%, respectively). Field investigation of occupational disease diagnosis reveals large numbers of cases of leukemia, suspected occupational benzene poisoning, suspected occupational hand-arm vibration disease, and suspected pneumoconiosis. The key aspects of field investigation include confirmation of the history of occupational

This article aims to define occupational rhinitis, classify its various causes, review the steps in its diagnosis, and describe its nonpharmacologic and pharmacologic principles of management. Occupational rhinitis frequently coexists with asthma but also occurs alone. Although it does not have the same impact as occupational asthma, occupational rhinitis causes distress, discomfort, and work inefficiency. By concentrating on the patient's workplace, the clinician has an opportunity to practice preventive medicine: to recognize substances in the patient's micro- and macroenvironment that are causing the problems and then to intervene by altering the environment or removing the patient from the environment.

Occupational accidents in the Finnish local government sector: utilisation of national statistics.
Nenonen, Noora
2011-12-01
Occupational accidents in the Finnish local government sector in 2004 are analysed by gender, age and occupation class in order to identify particular risk groups. The accident data are compared with data concerning the number of employees, using frequency distributions and accident incidence rates. The possibilities of providing occupation class-specific accident incidence rates are also discussed. According to the results, commuting accidents are more common and severe in the local government sector than in general in Finland. In the local public sector occupational accidents more often involved women than men. Compared to other age groups and occupational classes, occupational accidents are more common in the age band of 45-54 and in the occupational class of medical and nursing work. However, compared to the employees' data, men and younger employees had an increased workplace accident risk, while women and older employees had an increased risk of commuting accidents. The highest accident incidence rate was in farming and animal husbandry work. Currently, the calculation of occupation class-specific accident incidence rates is difficult. Improving the consistency of the occupation classifications used in the various data sources would facilitate more reliable calculation of rates.

Many infections are associated with occupations. Involvement in a particular occupation may place the person at higher direct risk of contracting certain infections. In some instances the life-style associated with the occupation results in a higher risk of exposure to the infection. The link between the infection and the workplace is often missed by the attending physician. This may be due to a lack of awareness on the part of the physician. Sometimes a direct link can be difficult to prove without the use of sophisticated molecular epidemiological tests. This has led to gross under-diagnosis and under-reporting of such cases. It is however important that occupational infections be diagnosed as adequate preventive measures need to be implemented. Furthermore the patient may be eligible for monetary compensation under the relevant occupational safety laws of the country.

Multiple myeloma (MM) is an incurable plasma cell malignancy with a poorly understood etiology. The purpose of our research was to examine the relationships between lifetime occupations and MM in a relatively large case-control study. MM cases (n = 180) were identified through cancer registries in the Seattle-Puget Sound area and Detroit. Population-based controls (n = 481) were identified using random digit dialing and Medicare and Medicaid Services files. In-person interviews were conducted to ascertain occupational histories. Standard occupational classification (SOC) and standard industrial classification (SIC) codes were assigned to each job held by each participant. Unconditional logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between MM and having ever worked in each occupation/industry and according to duration of employment in an occupation/industry. The risk of MM was associated with several manufacturing occupations and industries, including machine operators and tenders, not elsewhere classified (SOC 76) (OR = 1.8, CI = 1.0-3.3); textile, apparel, and furnishing machine operators and tenders (SOC 765) (OR = 6.0, CI = 1.7-21); and machinery manufacturing, except electrical (SIC 35) (OR = 3.3, CI = 1.7-6.7). Several service occupations and industries, such as food and beverage preparation (SOC 521) (OR = 2.0, CI = 1.1-3.8), were also associated with MM. One occupation that has been associated with MM in several previous studies, painters, paperhangers, and plasterers (SOC 644) was associated with a non-significantly elevated risk (OR = 3.6, CI = 0.7-19). We found associations between the risk of MM and employment in several manufacturing and service-related occupations and industries. Copyright 2010 Wiley-Liss, Inc.

Occupation is a human right and a social determinant of health. It is also taken for granted. Having access to, and participating in, occupation, is intricately linked to positive health and wellbeing. Despite theory and evidence to support the link between occupation, health and wellbeing, occupational therapists can struggle with applying an occupation focus in practice and knowing how to use occupational frameworks to enable occupation. The purpose of this paper is to introduce the Capabilities, Opportunities, Resources and Environments (CORE) approach for inclusive and occupation-focused practice. It provides occupational therapists with a means of operationalising occupational enablement and facilitating social inclusion. The CORE approach is introduced by linking its main ideas to Economist and Nobel Prize Laureate Amartya Sen's capabilities approach, as well as findings from the author's doctoral research into entrenched disadvantage and social inclusion. Practical questions guided by the CORE approach's acronym are given to explore how the approach can be utilised alongside other occupational models and frameworks to encourage strategies for effective enablement through occupation for social inclusion. As experts in enabling occupation, occupational therapists can use the CORE approach to design occupation-focused interventions and promote inclusive occupational therapy. © 2017 Occupational Therapy Australia.

To estimate the mortality rate due to occupational pesticide poisoning in Brazil. Data on diagnoses of death from pesticide poisoning between 2000 and 2009 were obtained from the Mortality Information System. ICD-10 codes T60.0-T60.4, T60.8 and T60.9, Y18, X487 and Z578 as the main or secondary cause of death; data on work-related deaths were obtained from the death certificate, from the fields
, and whether cases were agricultural workers. Homicides and suicides were excluded. To calculate mortality, the number of agricultural workers was obtained from the Brazilian Institute of Geography and Statistics, National System of Accounts estimates. There were 2,052 deaths recorded as caused by pesticide poisoning in Brazil, between 2000 and 2009, of which 36.2% (n = 743) had no occupation data. Of the remaining 1,309, 679 (51.9%) were agricultural workers. Mortality from occupational pesticide poisoning declined from 0.56/100.000 (2000-2001) to 0.39/100.000 (2008-2009) workers during the study period, and there was a larger decrease among men compared with women. Males had a higher mortality from this type of poisoning than women in all study years. Most deaths were caused by organophosphates and carbamate pesticides poisoning. During the study period the number of cases declined in all regions, except for the Northeast. Improvement in the quality of Death Certificate records is needed, particularly for occupation and the assessment of causes of death as work related, crucial for work injuries control and prevention programs. Special attention is required in the Northeast region. -

Occupational and genetic risk factors for osteoarthritis: A review
Yucesoy, Berran; Charles, Luenda E.; Baker, Brent; Burchfiel, Cecil M.
2015-01-01
BACKGROUND Osteoarthritis (OA) is a multifactorial disease with strong genetic and occupational components. Although published studies have described several risk factors for OA, very few studies have investigated the occupational and genetic factors that contribute to this debilitating condition. OBJECTIVE To describe occupational and genetic factors that may contribute to the risk of developing (OA). METHODS A literature search was conducted in PubMed using the search terms osteoarthritis, occupation, work, and genetics. RESULTS Heavy physical work load was the most common occupational risk factor for OA in several anatomical locations. Other factors include kneeling and regular stair climbing, crawling, bending and whole body vibration, and repetitive movements. Numerous studies have also shown the influence of genetic variability in the pathogenesis of OA. Genetic variants of several groups of genes e.g., cartilage extracellular matrix structural genes and the genes related to bone density have been implicated in disease pathogenesis. CONCLUSION This review shows that occupational factors were extensively studied in knee OA unlike OA of other anatomical regions. Although genetic association studies performed to date identified a number of risk variants, some of these associations have not been consistently replicated across different studies and populations. Therefore, more research is needed. PMID:24004806

Exposure to occupational therapy as a factor influencing recruitment to the profession.
Byrne, Nicole
2015-08-01
This article provides insight into the impact that exposure to an occupational therapist, in personal capacity or via a professional interaction, has on the decision to enter an occupational therapy undergraduate programme. A quantitative survey was completed by 139 occupational therapy students. The survey tool focussed on the students' exposure to a range of allied health professions (e.g. occupational therapy, physiotherapy, psychology) and investigated how exposure to occupational therapy had influenced their decision to enter the programme. The results indicated that over 70% of respondents had personal professional exposure to occupational therapy prior to making a career decision. Exposure most frequently involved occupational therapy intervention of a friend or family member. The majority of students who had professional exposure to occupational therapy (e.g. family, self, friend received occupational therapy) identified that it was the most influential factor in their career choice. Forty per cent of the occupational therapy students did not enter the programme straight from school and the influence of 'working with an occupational therapist' was noteworthy for mature aged students. Occupational therapists need to consider that every interaction they have with the community provides valuable information regarding the profession and gives insight into occupational therapy as a potential career path for other people. Additionally, the current research identifies there were differences in the impact, type and number of exposures for different student groups, and this potentially offers some insight into ways in which occupational therapy could target specific groups within the community to increase future diversity in the profession. © 2015 Occupational Therapy Australia.

Occupational position is one of the determinants of psychological health, but this association may differ for men and women depending on the social context. In contemporary Japanese society, occupational gender segregation persists despite increased numbers of women participating in the labour market, which may contribute to gender specific patterns in the prevalence of poor psychological health. The present study examined gender specific associations between occupational position and psychological health in Japan, and the potential mediating effects of job control and effort-reward imbalance in these associations. We used data obtained from 7123 men and 2222 women, aged between 18 and 65 years, who participated in an occupational cohort study, the Japanese Study of Health, Occupation, and Psychosocial Factors Related Equity (J-HOPE), between 2011 and 2012. We used logistic regression to examine the association between occupational position and poor psychological health, adjusted for age, working hours, household income and education, as well as psychosocial work characteristics (job control and effort-reward imbalance). The prevalence of poor psychological health increased from manual/service occupations (23%) to professionals/managers (38%) among women, while it did not vary by occupational position among men. In women, the significant association between occupational position and psychological health was not explained by job control, but was attenuated by effort-reward imbalance. Our findings suggest that Japanese women in more advantaged occupational positions are likely to be at a greater risk for poor psychological health due to higher levels of effort-reward imbalance at work.

Profitability and occupational injuries in U.S. underground coal mines.
Asfaw, Abay; Mark, Christopher; Pana-Cryan, Regina
2013-01-01
Coal plays a crucial role in the U.S. economy yet underground coal mining continues to be one of the most dangerous occupations in the country. In addition, there are large variations in both profitability and the incidence of occupational injuries across mines. The objective of this study was to examine the association between profitability and the incidence rate of occupational injuries in U.S. underground coal mines between 1992 and 2008. We used mine-specific data on annual hours worked, geographic location, and the number of occupational injuries suffered annually from the employment and accident/injury databases of the Mine Safety and Health Administration, and mine-specific data on annual revenue from coal sales, mine age, workforce union status, and mining method from the U.S. Energy Information Administration. A total of 5669 mine-year observations (number of mines×number of years) were included in our analysis. We used a negative binomial random effects model that was appropriate for analyzing panel (combined time-series and cross-sectional) injury data that were non-negative and discrete. The dependent variable, occupational injury, was measured in three different and non-mutually exclusive ways: all reported fatal and nonfatal injuries, reported nonfatal injuries with lost workdays, and the 'most serious' (i.e. sum of fatal and serious nonfatal) injuries reported. The total number of hours worked in each mine and year examined was used as an exposure variable. Profitability, the main explanatory variable, was approximated by revenue per hour worked. Our model included mine age, workforce union status, mining method, and geographic location as additional control variables. After controlling for other variables, a 10% increase in real total revenue per hour worked was associated with 0.9%, 1.1%, and 1.6% decrease, respectively, in the incidence rates of all reported injuries, reported injuries with lost workdays, and the most serious injuries reported

An outbreak of cholangiocarcinoma in a printing company was reported in Japan, and these cases were regarded as an occupational disease (occupational cholangiocarcinoma). This study examined the expression status of programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) in occupational cholangiocarcinoma. Immunostaining of PD-1, PD-L1, CD3, CD8, and CD163 was performed using tissue sections of occupational cholangiocarcinoma (n = 10), and the results were compared with those of control cases consisting of intrahepatic (n = 23) and extrahepatic (n = 45) cholangiocarcinoma. Carcinoma cells expressed PD-L1 in all cases of occupational cholangiocarcinoma, whereas the detection of PD-L1 expression in cholangiocarcinoma cells was limited to a low number of cases (less than 10%) in the control subjects. In cases of occupational cholangiocarcinoma, occasional PD-L1 expression was also noted in precancerous/preinvasive lesions such as biliary intraepithelial neoplasia and intraductal papillary neoplasm of the bile duct. Additionally, tumor-associated macrophages and tumor-infiltrating T cells expressed PD-L1 and PD-1, respectively. The number of PD-L1-positive mononuclear cells, PD-1-positive lymphocytes, and CD8-positive lymphocytes infiltrating within the tumor was significantly higher in occupational cholangiocarcinoma compared with that in control cases. These results indicate that immune escape via the PD-1/PD-L1 axis may be occurring in occupational cholangiocarcinoma. © 2017 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

The association between occupational exposure and stomach cancer was investigated in a multicenter case-referent study conducted in Spain on 354 histologically confirmed cases and 354 hospital referents, matched by age, gender, and residence. An increased risk of gastric cancer was found for coal mining workers [odds ratio (OR) 11.8], but the number of workers was small, and therefore the 95% confidence interval (95% CI) was wide (95% CI 1.36-103). An increased risk was observed for wood and furniture workers (OR 1.76), construction workers (OR 1.68), and glass and ceramic workers (OR 2.18), but none of these risks were statistically significant. According to an occupation-exposure linkage system an increased risk was found for occupations associated with exposure to silica and mineral dust (OR 1.80, 95% CI 0.90-3.59). All of the OR estimates were adjusted for the confounding factors socioprofessional status and dietary habits. The possibility of a causal association between stomach cancer and coal and mineral dust is supported by the results.

In the United States, regional poison centers frequently receive calls about toxic workplace exposures. Most poison centers do not share call details routinely with governmental regulatory agencies. Worker health and safety could be enhanced if regulators such as the Occupational Safety and Health Administration (OSHA) had the ability to investigate these events and prevent similar incidents. With this goal in mind, the Georgia Poison Center (GPC) began referring occupational exposures to OSHA in July 2014. GPC began collecting additional employer details when handling occupational exposure calls. When workers granted permission, GPC forwarded call details to the OSHA Regional Office in Atlanta. These referrals enabled OSHA to initiate several investigations. We also analyzed all occupational exposures reported to GPC during the study period to characterize the events, detect violations of OSHA reporting requirements, and identify hazardous scenarios that could form the basis for future OSHA rulemaking or guidance. GPC was informed about 953 occupational exposures between 1 July, 2014 and 7 January, 2016. Workers were exposed to 217 unique substances, and 70.3% of victims received treatment in a healthcare facility. Hydrogen sulfide was responsible for the largest number of severe clinical effects. GPC obtained permission to refer 89 (9.3%) calls to OSHA. As a result of these referrals, OSHA conducted 39 investigations and cited 15 employers for "serious" violations. OSHA forwarded several other referrals to other regulatory agencies when OSHA did not have jurisdiction. At least one employer failed to comply with OSHA's new rule that mandates reporting of all work-related hospitalizations. This collaboration increased OSHA's awareness of dangerous job tasks including hydrofluoric acid exposure among auto detailers and carbon monoxide poisoning with indoor use of gasoline-powered tools. Collaboration with the GPC generated a useful source of referrals to OSHA. OSHA

Occupational contact dermatitis.
Lushniak, Boris D
2004-01-01
The dermatologist should be aware of the many facets of occupational skin diseases, which can be caused by physical, chemical, and biological insults. The most common manifestation of occupational skin diseases is contact dermatitis (both irritant and allergic). Three factors point out the importance of occupational skin diseases as diseases that have a public health impact: 1) occupational skin diseases are common; 2) they often have a poor prognosis; and 3) they result in a noteworthy economic impact for society and for an individual. They are also diseases amenable to public health interventions. Specific industries and exposures may put a worker at risk of occupational contact dermatitis. The accuracy of the diagnosis of occupational contact dermatitis is related to the skill level, experience, and knowledge of the medical professional who makes the diagnosis and confirms the relationship with a workplace exposure. Prevention of occupational contact dermatitis is important, and a variety of prevention strategies are available.

Occupational exposure to glycol ethers: implications for occupational health nurses.
Snow, J E
1994-09-01
1. Evaluation of workplace exposure to reproductive hazards is difficult and is often confounded by occupational exposure to multiple agents and exposure to non-occupational factors. 2. A growing body of evidence from animal and human study data supports a causal association between occupational exposure to certain glycol ethers and adverse reproductive outcomes. 3. Occupational health nurses providing services to employees exposed to glycol ethers should remain knowledgeable about the results of epidemiologic studies and current trends in the regulation of glycol ethers in industry. 4. Occupational health nurses are in a key position to reduce exposure to reproductive hazards by monitoring trends in group data and by implementing training and education programs to employees exposed to reproductive hazards.

Suicide Mortality Across Broad Occupational Groups in Greece: A Descriptive Study
Alexopoulos, Evangelos C.; Kavalidou, Katerina; Messolora, Fani
2015-01-01
Background Several studies have investigated the relationship between specific occupations and suicide mortality, as suicide rates differ by profession. The aim of this study was to investigate suicide mortality ratios across broad occupational groups in Greece for both sexes in the period 2000–2009. Methods Data of suicide deaths were retrieved from the Hellenic Statistical Authority and comparative mortality ratios were calculated. Occupational classification was based on the International Classification of Occupations (ISCO-88) and the coding for Intentional self-harm (X60–X84) was based on the international classification of diseases (ICD-10). Results Male dominant occupations, mainly armed forces, skilled farmers and elementary workers, and female high-skilled occupations were seen as high risk groups for suicide in a period of 10 years. The age-productive group of 30–39 years in Greek male elementary workers and the 50–59 age-productive group of Greek professional women proved to have the most elevated number of suicide deaths. Conclusion Further research is needed into the work-related stressors of occupations with high suicide mortality risk and focused suicide prevention strategies should be applied within vulnerable working age populations.

Challenges and Opportunities for Occupational Epidemiology in the Twenty-first Century.
Stayner, L T; Collins, J J; Guo, Y L; Heederik, D; Kogevinas, M; Steenland, K; Wesseling, C; Demers, P A
2017-09-01
There are many opportunities and challenges for conducting occupational epidemiologic studies today. In this paper, we summarize the discussion of a symposium held at the Epidemiology in Occupational Health (EPICOH) conference, Chicago 2014, on challenges for occupational epidemiology in the twenty-first century. The increasing number of publications and attendance at our conferences suggests that worldwide interest in occupational epidemiology has been growing. There are clearly abundant opportunities for new research in occupational epidemiology. Areas ripe for further work include developing improved methods for exposure assessment, statistical analysis, studying migrant workers and other vulnerable populations, the use of biomarkers, and new hazards. Several major challenges are also discussed such as the rapidly changing nature and location of work, lack of funding, and political/legal conflicts. As long as work exists there will be occupational diseases that demand our attention, and a need for epidemiologic studies designed to characterize these risks and to support the development of preventive strategies. Despite the challenges and given the important past contribution in this field, we are optimistic about the importance and continued vitality of the research field of occupational epidemiology.

This study was conducted to investigate the associations among work-related musculoskeletal disorders (WMSDs), job stress, and job attitude of occupational therapists in South Korea. Self-reporting questionnaires were distributed to 150 occupational therapists. Of the 128 occupational therapists who responded, 110 (85.9%) reported WMSDs affecting at least one body site. The most affected WMSDs site was the low back (26.8%), and the most reported number of body site affected by WMSDs was one (53.9%). As a result, there were significant differences in job stress and job attitude depending on the age, work experience, working hour, presence or absence of WMSDs, and number of site of pain. Factors influencing job attitude included job stress, the presence or absence of WMSDs and duration of pain. The results showed that the occurrence of WMSDs in occupational therapists was associated with increased job stress and negative job attitude.

Increased occupational radiation doses: nuclear fuel cycle.
Bouville, André; Kryuchkov, Victor
2014-02-01
The increased occupational doses resulting from the Chernobyl nuclear reactor accident that occurred in Ukraine in April 1986, the reactor accident of Fukushima that took place in Japan in March 2011, and the early operations of the Mayak Production Association in Russia in the 1940s and 1950s are presented and discussed. For comparison purposes, the occupational doses due to the other two major reactor accidents (Windscale in the United Kingdom in 1957 and Three Mile Island in the United States in 1979) and to the main plutonium-producing facility in the United States (Hanford Works) are also covered but in less detail. Both for the Chernobyl nuclear reactor accident and the routine operations at Mayak, the considerable efforts made to reconstruct individual doses from external irradiation to a large number of workers revealed that the recorded doses had been overestimated by a factor of about two.Introduction of Increased Occupational Exposures: Nuclear Industry Workers.

Parental occupation and childhood cancer: review of epidemiologic studies.
Savitz, D A; Chen, J H
1990-01-01
Parental occupational exposures might affect childhood cancer in the offspring through genetic changes in the ovum or sperm or through transplacental carcinogenesis. The 24 published epidemiologic studies of this association have all used case-control designs, with controls generally selected from birth certificates or from general population sampling. Occupational exposures were inferred from job titles on birth certificates or through interviews. A large number of occupation-cancer associations have been reported, many of which were not addressed or not confirmed in other studies. Several associations have been found with consistency: paternal exposures in hydrocarbon-associated occupations, the petroleum and chemical industries, and especially paint exposures have been associated with brain cancer; paint exposures have also been linked to leukemias. Maternal exposures have received much less attention, but studies have yielded strongly suggestive results linking a variety of occupational exposures to leukemia and brain cancer. The primary limitations in this literature are the inaccuracy inherent in assigning exposure based on job title alone and imprecision due to limited study size. Although no etiologic associations have been firmly established by these studies, the public health concerns and suggestive data warrant continued research. PMID:2272330

Occupational medicine for policing.
Trottier, A; Brown, J
1995-06-01
several US states have policies in place to unquestioningly accept atherosclerotic heart disease among police officers as 'occupationally induced' for pension purposes. This leads to situations where the scientific evidence may be at odds with the political agenda of individuals and groups participating in the determination. This review will examine the evidence for a number of medical conditions. Specific occupational exposures, such as lead exposure among ballistics specialists, or chemical exposure among forensic laboratory workers are addressed elsewhere. Biohazard risks will be addressed in a later review.

2014-05-01
General practitioners play or should play a role in occupational medicine (OM), either in diagnosing occupational diseases or in counseling on return to work. Nevertheless, their training has been reported to be insufficient in most single country studies. The objectives of this study were to analyze the content and extent of undergraduate teaching of OM in European medical schools. An e-mail questionnaire survey of the teaching of OM to undergraduates was undertaken from December 2010 to April 2011 in all medical schools and medical faculties listed in 27 European countries (n = 305). Among the 305 universities identified, 135 answered to the questionnaire, giving a response rate of 44%. The mean number of hours given to formal instruction in occupational medicine to medical undergraduates was 25.5 h. Nevertheless, this number of hours varied widely between countries, but also within countries. Overall, 27% of medical schools gave their students 10 h of teaching or less, 52% 20 h or less and 69% 30 h or less. Whereas occupational diseases and principles of prevention were covered in most schools, disability and return to work were very poorly represented among the topics that were taught to students. Dedicated undergraduate teaching on occupational health or OM in European medical schools is present in most medical schools, usually at a low level, but is very variable between and within countries. Medical schools across Europe are very unequal to provide qualifying doctors education on the topics they will frequently come across in their working lives.

Occupational accidents in Russia and the Russian Arctic
Dudarev, Alexey A.; Karnachev, Igor P.; Odland, Jon Øyvind
2013-01-01
Background According to official statistics, the rate of occupational accidents (OAs) and fatal injuries in Russia decreased about 5-fold and 2-fold, respectively, from 1975 to 2010, but working conditions during this period had the opposite trend; for example, the number of people who work in unfavourable and hazardous conditions (particularly since 1991) has increased significantly. Methods This review summarises the results of a search of the relevant peer-reviewed literature published in Russia and official statistics on OAs and occupational safety in Russia and the Russian Arctic in 1980–2010. Results The occupational safety system in Russia has severely deteriorated in the last 2 decades, with legislators tending to promote the interests of industry and business, resulting in the neglect of occupational safety and violation of workers’ rights. The majority of workers are employed in conditions that do not meet rules of safety and hygiene. More than 60% of OAs can be attributed to management practices – violation of safety regulations, poor organisation of work, deficiency of certified occupational safety specialists and inadequate personnel training. Research aimed at improving occupational safety and health is underfunded. There is evidence of widespread under-reporting of OAs, including fatal accidents. Three federal agencies are responsible for OAs recording; their data differ from each other as they use different methodologies. The rate of fatal OAs in Russia was 3–6 times higher than in Scandinavian countries and about 2 times higher compared to United States and Canada in 2001. In some Russian Arctic regions OAs levels are much higher. Conclusions Urgent improvement of occupational health and safety across Russia, especially in the Arctic regions, is needed. PMID:23519652

Maternal occupational cadmium exposure and nonsyndromic orofacial clefts.
Suhl, Jonathan; Romitti, Paul A; Cao, Yanyan; Rocheleau, Carissa M; Burns, Trudy L; Conway, Kristin; Rajaraman, Preetha; Agopian, A J; Stewart, Patricia
2018-04-17
Cigarette smoking is a well-studied risk factor for orofacial clefts (OFCs). Little is known about which constituents in cigarette smoke contribute to this teratogenicity in humans. One constituent, cadmium, has been associated with OFCs in animal studies; in humans, the role of maternal cadmium exposure on OFCs, independent of cigarette smoke, is unclear. In particular, the relation between maternal occupational cadmium exposure and OFCs is largely unexplored. Using data from a large, population-based case-control study, we compared expert rater assessed maternal occupational cadmium exposure from self-reported occupational histories during the period 1 month before through 3 months after conception between OFC cases (n = 1,185) and unaffected controls (n = 2,832). Multivariable logistic regression analyses were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals for any (yes/no) and cumulative (no, low, high exposure) occupational cadmium exposures and all OFCs, cleft lip ± cleft palate (CL/P) and cleft palate (CP). Overall, 45 mothers (cases = 13, controls = 32) were rated as having occupational cadmium exposure. Comparing all OFCs to controls, we observed inverse, nonsignificant aORs for any or low exposure, and positive, nonsignificant aORs for high exposure. Where data were available, aORs for CL/P and CP tended to parallel those for all OFCs. To our knowledge, this is the first study to specifically examine maternal occupational cadmium exposure and OFCs, using expert rater exposure assessment. The small numbers of exposed mothers observed, however, led to imprecise estimates. Continued research using more detailed occupational exposure assessment and increased sample sizes is recommended. © 2018 Wiley Periodicals, Inc.

Nurses make a bureaucracy work on behalf of clients. Occupational health nurses who are already versed in basic concepts applicable to EEOICPA--confidence intervals, occupational histories, exposure assessment, and dose response--can play constructive, caring roles in assisting claimants in securing benefits under this landmark program. Occupational health nurses know that chronically ill employees have a finite number of hours a week to make phone calls, visit providers, and advocate on their own behalf. Thoughtful referrals to occupational health providers who are both experienced and supportive can come from an occupational health nurse or a family physician. Involvement of university-based programs in projects to empower organizations representing EEOICP claimants would be a welcome development.

Number of sick leave days vary by county, but little is known about the extent to which this gradient may be explained by differences pertaining to occupational composition and occupational exposure. A randomly drawn cohort from the general population in Norway, aged 18-69 years, was interviewed by telephone in the second half of 2009 ( n=12,255; response at baseline=60.9%) and followed up in national registries to the end of 2010. Eligible respondents were registered with an active employee relationship in 2009 and 2010 ( n=8275). Information on counties ( n=19) was based on the administrative register. The outcome of interest was the number of physician-certified sick-leave days divided by scheduled man-days during 2010 (i.e. sick-leave percentage (SLP)). The average SLP during 2010 was 5.2%. The between-county variation in SLP ranged from 4.0% to 7.2%. Compared to the age- and gender-adjusted model, adjustment for occupation, economic sector and self-reported occupational exposure reduced the median difference in SLP between the county with the lowest SLP (reference county) and the SLP in the other counties by 1.08 percentage points (i.e. a 58% reduction). The impact of occupational composition and occupational exposure on the total between-county variance in SLP was a 16% reduction. Occupational composition and self-reported occupational exposure help to explain a significant part of the difference in SLP between counties, and appear to be more important explanatory factors than demographic variables, self-reported health and smoking.

Occupational Lymphohematopoietic Cancer in Korea
Lee, Won Jin; Son, Mia; Kang, Seong-Kyu
2010-01-01
The purpose of this study was to review the existing studies on lymphohematopoietic (LHP) cancer in Korea, estimate the prevalence of workers exposed to carcinogens, and determine the population attributable fraction (PAF) of leukemia. Two case series and 4 case reports were reviewed. Using official statistics, the prevalence of benzene exposure and ionizing radiation exposure was estimated. Based on the prevalence of exposure and the relative risk, The PAF of leukemia was calculated. Between 1996 and 2005, 51 cases of LHP cancer were reported from the compensation system. Greater than 50% of occupational LHP cancer was leukemia, and the most important cause was benzene. In a cohort study, the standardized incidence ratio was 2.71 (95% CI, 0.56-7.91). The prevalence of exposure was 2.5% and 2.2% in 1995 and 2000, respectively. Using the 1995 prevalence, 3.6-4.8% and 0.1% of cases with leukemia were attributable to benzene and ionizing radiation exposure, respectively, which resulted in 39.7-51.4 cases per year. Benzene is the most important cause of occupational leukemia in Korea. Considering the estimated PAF in this study, the annual number of occupational LHP cancer (51 cases during 10-yr period), might be underreported within the compensation system. PMID:21258598

Accurate estimates of the distribution and abundance of endangered species are crucial to determine their status and plan recovery options, but such estimates are often difficult to obtain for species with low detection probabilities or that occur in inaccessible habitats. The Puaiohi (Myadestes palmeri) is a cryptic species endemic to Kauaʻi, Hawai‘i, and restricted to high elevation ravines that are largely inaccessible. To improve current population estimates, we developed an approach to model distribution and abundance of Puaiohi across their range by linking occupancy surveys to habitat characteristics, territory density, and landscape attributes. Occupancy per station ranged from 0.17 to 0.82, and was best predicted by the number and vertical extent of cliffs, cliff slope, stream width, and elevation. To link occupancy estimates with abundance, we used territory mapping data to estimate the average number of territories per survey station (0.44 and 0.66 territories per station in low and high occupancy streams, respectively), and the average number of individuals per territory (1.9). We then modeled Puaiohi occupancy as a function of two remote-sensed measures of habitat (stream sinuosity and elevation) to predict occupancy across its entire range. We combined predicted occupancy with estimates of birds per station to produce a global population estimate of 494 (95% CI 414–580) individuals. Our approach is a model for using multiple independent sources of information to accurately track population trends, and we discuss future directions for modeling abundance of this, and other, rare species.

Occupational therapists and patients' rights: their level of Clinical knowledge.
Dehghan, Leila; Dalvand, Hamid; Haghgoo, Hojjat Allah; Hosseini, Seyed Ali; Karimlou, Masoud
2013-01-01
Addressing patients' rights issues brings occupational therapists ethical and political responsibilities that involve patients' privileges and new facilitating factors which influence their needs. The goal of this study was to determine the level of occupational therapists' knowledge about patients' rights. The present research was a cross-sectional study which involved 125 occupational therapists chosen by a convenience sampling strategy in Tehran during the year of 2012. A four-part questionnaire was used for data collection, and the degree of the subjects' self-assessment of their knowledge was measured based on the obtained numbers of correct answers in the third part. The validity and reliability of this questionnaire were assessed prior to its being distributed among participants. The results demonstrated no significant association between the level of occupational therapists' knowledge about patients' rights and their existing experiences within their areas of occupational therapy (P>0.05). Based on the result, 53.6% of the respondents had high level of knowledge about patients' rights. Facilitating factors which influence the attainment of patients' rights were classified into three groups: organizations, therapists and clients. The results of the present research demonstrated that the level of occupational therapists' knowledge about patients' rights were high. Furthermore, this study showed that for optimal result, there is a need to provide milieu for observing the patients' rights in clinical occupational therapy services.

Exposure-response relationships of occupational inhalative allergens.
Baur, X; Chen, Z; Liebers, V
1998-05-01
Only a few threshold limit values exist at present for allergens in the workplace known to cause bronchial asthma. This contrasts with the great number of occupational asthma cases observed in industrialized countries. Recently published studies provide clear evidence for exposure intensity response relationships of occupational allergens of plant, microbiological, animal or man-made origin. If allergen exposure levels fall short of determined limit values, they are not associated with an increased risk of occupational asthma. Corresponding data are available for wheat flour (1-2.4 mg/m3), fungal alpha-amylase (0.25 ng/m3), natural rubber latex (0.6 ng/m3), western red cedar (0.4 mg/m3) and rat allergens (0.7 microg/m3). It is suggested to stipulate legally binding threshold limit values (TLV/TWA) on this basis in order to induce more effective primary preventive measures. If no reliable data on the health risk of an occupational airborne noxa exist, the lowest reasonably practicable exposure level has to be achieved. Appropriate secondary preventive measures have to be initiated in all workplaces contaminated with airborne allergens. Verified exposure-response relationships provide the basis for risk assessment and for targeted interventions to reduce the incidence of occupational asthma also in consideration of cost benefit aspects. 'Occupational asthma is a disease characterized by variable airflow limitation and/or airway hyperresponsiveness due to causes in a working environment. These causes can give rise to asthma through immunological or non-immunological mechanisms. Up to 15% of all asthma cases are of occupational origin or have at least a significant causal occupational factor. According to the New Zealand part of the European Respiratory Health Survey, an increased risk of asthma prevalence was found for several occupations such as laboratory technicians, food producers, chemical workers, plastic and rubber workers. The Spain part of this study

Occupational stress in nursing: a review of the literature.
Clegg, A
2001-03-01
The management and reduction of occupational stress are recognized as key factors in promoting employee well-being. Nursing is one of the many disciplines contributing to a huge body of research into the causes and effect of the ill-defined phenomenon of occupational stress. This literature review considers the ontological contribution of a number of disciplines to a growing body of knowledge on the subject of stress. The paper examines the complex issue of stress management, highlighting the impact of organizational culture and transformational leadership style on staff satisfaction levels.

Sex-linked occupational differentiation has been seen as influenced by both the industrial structure of the economy and the sex composition of the labor force. Here, with a sample of 70 SMSAs, it was found (a) that the odds of men relative to women of joining professional and managerial occupations increased between 1960 and 1970, and (b) that this increase was dependent on the growth of tertiary industries and the greater number of women joining the cash economy. The observed effect of industrial shifts on sex-occupational differentiation, however, is argued to be a spurious consequence of the gender-composition of the work force. Specifically, the development of tertiary industries generates greater demand for female labor. Intensive recruitment of women to the labor force in turn increases occupational differentiation because females, in sex-typed labor markets, are likely to be channeled in disproportionate numbers away from upper-status occupations. The findings demonstrate that traditional modernization theory is unable to account for this. However, the results lend support to expectations derived from a labor market sex-segmentation approach.

Occupational therapy practice in emergency care: Occupational therapists' perspectives.
Spang, Lisa; Holmqvist, Kajsa
2015-01-01
Emergency care takes place in a complex work environment that is characterized by critically ill patients, short hospital stays, and a wide variety of different healthcare professionals. Studies of occupational therapists' (OTs) experiences of working within emergency care have shown that they often experience difficulties in explaining the essence of occupational therapy and have to justify their approaches. Much effort has been made in Sweden to help OTs dispel the notion that occupational therapy is difficult to explain, and the aim of this study was to describe how Swedish OTs perceive their work in emergency care. A qualitative descriptive approach was taken, and 14 interviews were conducted with OTs working in emergency care. Qualitative content analysis was used to analyse the data. The overall theme that emerged was "Feeling established through deliberate occupation-based work". The underlying categories showed different strategies used by the OTs to provide occupational therapy in an emergency care context. Deliberate strategies were used to demonstrate the effectiveness of occupational therapy and its approaches to patients and other health care professionals, and this resulted in the OTs feeling both established and needed. Unlike the OTs in previous studies, the Swedish OTs experienced no difficulties in explaining occupational therapy and could make convincing arguments for their interventions. Parallel to their clinical work, the OTs worked with on-going development to find ways to improve their approaches. In summary, these Swedish OTs seem to have been provided with a professional language and the knowledge required to establish themselves in an emergency care setting.

Motion-activated cameras are a versatile tool that wildlife biologists can use for sampling wild animal populations to estimate species occurrence. Occupancy modelling provides a flexible framework for the analysis of these data; explicitly recognizing that given a species occupies an area the probability of detecting it is often less than one. Despite the number of studies using camera data in an occupancy framework, there is only limited guidance from the scientific literature about survey design trade-offs when using motion-activated cameras. A fuller understanding of these trade-offs will allow researchers to maximise available resources and determine whether the objectives of a monitoring program or research study are achievable. We use an empirical dataset collected from 40 cameras deployed across 160 km2 of the Western Slope of Colorado, USA to explore how survey effort (number of cameras deployed and the length of sampling period) affects the accuracy and precision (i.e., error) of the occupancy estimate for ten mammal and three virtual species. We do this using a simulation approach where species occupancy and detection parameters were informed by empirical data from motion-activated cameras. A total of 54 survey designs were considered by varying combinations of sites (10–120 cameras) and occasions (20–120 survey days). Our findings demonstrate that increasing total sampling effort generally decreases error associated with the occupancy estimate, but changing the number of sites or sampling duration can have very different results, depending on whether a species is spatially common or rare (occupancy = ψ) and easy or hard to detect when available (detection probability = p). For rare species with a low probability of detection (i.e., raccoon and spotted skunk) the required survey effort includes maximizing the number of sites and the number of survey days, often to a level that may be logistically unrealistic for many studies. For common species with

Occupational Health in Eastern Europe
Malan, R. M.
1963-01-01
Progress may be fostered as much by spreading information as by research. The aim of this review is to add to the existing knowledge of the pattern of occupational health services in the socialist countries of Eastern Europe. The work consists of two main parts. Part I is based on official information issued by government departments or typewritten reports prepared by government officials, and relates mostly to the Union of Soviet Socialist Republics and to Czechoslovakia. Part II is largely based on direct observation, discussion, and comparison of the occupational health services in Czechoslovakia, of which I have more extensive knowledge than of the other countries of Eastern Europe. This part embodies a number of conclusions and is followed by a list of bibliographical references. Throughout the review I have endeavoured to show how problems which exist all over the world are dealt with in Eastern Europe. PMID:13932439

High-risk occupations for women exposed to cadmium.
Freeman, C S
1994-08-01
Occupational exposures to cadmium are associated with increased risk of lung cancer and renal disease. The Occupational Safety and Health Administration (OSHA) published two standards for cadmium on September 14, 1992 that reduced the permissible occupational exposure limit. In the cadmium industry, women were less likely to be exposed to high levels of cadmium and more likely to hold job titles containing the word "hand" than were men. Only small numbers of female workers were exposed to any level of cadmium. OSHA's risk assessment relied, in part, on morbidity and mortality data from male workers and in part on rodent (animal) data from both sexes. OSHA did not evaluate illness rates specific to female workers. Several factors may alter the risk of these illnesses and their sequelae among workers, including differences in smoking, route of exposures, ability to wear personal protective equipment, and lifestyle.

Liver cancer is the second leading worldwide cause of cancer-associated mortalities. Hepatocellular carcinoma, which accounts for the majority of liver tumors, ranks fifth among types of human cancer. Well-established risk factors for liver cancer include the hepatitis B and C viruses, aflatoxins, alcohol consumption, and oral contraceptives. Tobacco smoking, androgenic steroids, and diabetes mellitus are suspected risk factors. Current knowledge regarding non-infective occupational risk factors for liver cancer is inconclusive. The relevance of liver disorders to occupational medicine lies in the fact that the majority of chemicals are metabolized in the liver, and toxic metabolites generated via metabolism are the predominant cause of liver damage. However, their non-specific clinical manifestations that are similar in a number of liver diseases make diagnosis difficult. Furthermore, concomitant conditions, such as viral hepatitis and alcohol or drug abuse, may mask liver disorders that result from occupational hepatotoxic agents and block the demonstration of an occupational cause. The identification of environmental agents that result in human cancer is a long and often difficult process. The purpose of the present review is to summarize current knowledge regarding the association of non-infective occupational risk exposure and HCC, to encourage further research and draw attention to this global occupational public health problem.

[Occupational injuries among construction workers in Hong Kong].
Huang, Zihui; Chen, Weiqing
2002-02-01
To explore the nature and severity of occupational injuries among construction workers and its risk factors in Hong Kong. One hundred and twenty-two injured construction workers in a public hospital and an equal number of workmate controls were studied. Contents included socio -demographic characteristics, the availability and use of safety equipment, smoking and alcohol consumption, etc. Abbreviated injury scale (AIS) and injury severity score (ISS) were employed for describing the nature, pattern and severity of injuries. Single injuries were seen in 80% of cases. Of 149 injuries classified by body region, 49% were external, 26% involved either the upper or lower extremities, and 11% were spinal injuries. Working at height was associated with the injury severity score. Safety hazards were identified in the work environment in 68% of the cases. Significant odds ratios for accidents were obtained for 'no formal education', 'non safety training' and 'current smokers'. The results implicated that construction was a hazardous occupation in Hong Kong. Improving the work environment and promoting safety education among construction workers would be helpful for minimizing or eliminating occupational injuries in construction occupation in Hong Kong.

Enabling occupation at the end of life: A literature review.
Mills, Katherine; Payne, Angela
2015-12-01
Occupation, or meaningful activity, can contribute to the well-being and quality of life of all individuals. It is thus a logical tautology that occupation should be enabled for those at the end of life. Our present review examines current provision of these processes by Occupational Therapist, who can be much-valued members of multidisciplinary palliative care teams. Following a literature search and critical selection, 10 global papers were identified examining occupation and occupational therapy at the end of life in the acute, hospice, and community environments. Universally, there appeared to be a dearth of therapists working in end-of-life care. Provision of palliative care in hospitals was found to be compensatory or rehabilitative. Hospice therapy emerged as pleasingly occupational, though the number of hospice places was disappointingly few. Community literature was sparse, so it proved challenging to draw definitive conclusions. Promising research refracted light on occupation at home; however, it also revealed stretched domiciliary services, where clients are not well informed about the potential scope of occupational therapy. A "good death" involving a quality end-of-life experience is the foundational goal overarching all therapy and medicine in the provision of palliative care. Arguably, an occupation-focused approach provided by therapists meets client needs to enable meaningful experiences in the limited time left to them. Current occupational therapy practice environments are not necessarily achieving these goals in commensurate fashion. There is a need to promote the role of occupational therapy and circumscribe what therapists can offer. Further research is necessitated across all environments and future funding for therapist positions in palliative teams. End-of-life care can be complex and challenging; however, therapists can facilitate fulfillment of client-centered occupational goals. In engaging with personally constructed nuances of meaning

Occupation has been the focus in occupational therapy practice to greater or lesser degrees from a historical viewpoint. This evokes a need to discuss whether concepts that are added to our field will enhance or blur our focus on occupation. To explore how the concept of participation in the International Classification of Functioning, Disability and Health (ICF) is related to the concept of occupation by reviewing and comparing its use in three models of practice within occupational therapy. The aim was also to generate discussion on possibilities and challenges concerning the relationship of participation and occupation. The models reviewed were The Model of Human Occupation (MOHO), the Canadian Model of Occupational Performance and Engagement (CMOP-E) and the Occupational Therapy Intervention Process Model (OTIPM). The concept of participation was related to occupation in different ways in these models. Based on the review some challenges and considerations for occupational therapy were generated. Relating the concept of participation from the ICF to the concept of occupation in models of practice can be challenging. At the same time, relating the concepts can be a resource to develop occupational therapy and the understanding of occupational issues in society.

The burden of occupationally-related cutaneous malignant melanoma in Britain due to solar radiation.
Rushton, Lesley; J Hutchings, Sally
2017-02-14
Increasing evidence highlights the association of occupational exposure and cutaneous malignant melanoma (CMM). We estimated the burden of CMM and total skin cancer burden in Britain due to occupational solar radiation exposure. Attributable fractions (AF) and numbers were estimated for CMM mortality and incidence using risk estimates from the published literature and national data sources for proportions exposed. We extended existing methods to account for the exposed population age structure. The estimated total AF for CMM is 2.0% (95% CI: 1.4-2.7%), giving 48 (95% CI: 33-64) deaths in (2012) and 241 (95% CI: 168-325) registrations (in 2011) attributable to occupational exposure to solar radiation. Higher exposure and larger numbers exposed led to much higher numbers for men than women. Industries of concern are construction, agriculture, public administration and defence, and land transport. These results emphasise the urgent need to develop appropriate strategies to reduce this burden.

Tobacco use is the second cause of death and first cause of preventable mortality worldwide. Smoking in the workplace is particularly concerning. Smoking-free workplaces decrease the risk of exposure of non-smoking personnel to cigarette smoke. Recent studies have mostly focused on the effect of daily or non-occupational stressors (in comparison with occupational stress) on prevalence of smoking. Occupational stress is often evaluated in workplaces for smoking cessation or control programs, but the role of non-occupational stressors is often disregarded in this respect. This cross-sectional study was conducted in an automobile manufacturing company. The response of automotive industry workers to parts of the validated, reliable, Farsi version of Musculoskeletal Intervention Center (MUSIC)-Norrtalje questionnaire was evaluated. A total of 3,536 factory workers participated in this study. Data were analyzed using SPSS and P<0.05 was considered statistically significant. The correlation of smoking with demographic factors, occupational stressors and life events was evaluated. The results of logistic regression analysis showed that even after adjusting for the confounding factors, cigarette smoking was significantly correlated with age, sex, level of education, job control and life events (P<0.05). The results showed that of occupational and non-occupational stressors, only job control was correlated with cigarette smoking. Non-occupational stressors had greater effect on cigarette smoking. Consideration of both non-occupational and occupational stressors can enhance the success of smoking control programs. On the other hand, a combination of smoking control and stress (occupational and non-occupational) control programs can be more effective than smoking cessation interventions alone.

[The Effect of Social-Psychological Factors on the Development of Occupational Stress].
Kalinina, S A; Yushkova, O I
2015-01-01
The article presents data on social-psychological factors which cause the occupational stress. The results showed that there is a link between the level of work motivation and the physiological cost of work. We observed a number of peculiarities of occupational stress development caused by psychoemotional tension depending on the class of intensity of intellectual labor; we also studied biological age of the subjects. The speed of ageing of the employees who work under conditions of emotional stress (direct or indirect responsibility for the safety of other people) was found to increase. The study suggested promising directions of occupational stress prevention.

Women's occupational health: a critical review and discussion of current issues.
Messing, K
1997-01-01
Action to improve women's occupational health has been slowed by a notion that women's jobs are safe and that any health problems identified among women workers can be attributed to unfitness for the job or unnecessary complaining. With increasing numbers of women in the labor force, the effects of work on women's health have recently started to interest health care providers, health and safety representatives and researchers. We begin our summary of their discoveries with a discussion of women's place in the workplace and its implications for occupational health, followed by a brief review of some gender-insensitive data-gathering techniques. We have then chosen to concentrate on the following four areas: methods and data collection; directing attention to women's occupational health problems; musculoskeletal disease; mental and emotional stress. We conclude by pointing out some neglected occupational groups and health issues.

[Causes of occupational injuries in Spain: a longitudinal analysis with panel data].
García Mainar, Inmaculada; Montuenga Gómez, Víctor
2009-01-01
To investigate the influence of several personal and occupational characteristics on the occurrence of occupation injuries, expressed in different categories (minor, serious, fatal and overall) by applying tools that are widely used in economic analyses. Panel data were used to estimate occupational injuries in an aggregate manner: both by regions and occupational categories and by industries and occupational categories. Data on occupational injuries were drawn from the Ministry of Labor and Social Affairs while the remaining information was drawn from the Workforce Population Survey for all quarters from 1999 to 2002. Permanent workers, male workers, public sector employees and those with secondary education or who had received on-the-job training were safer at their workplaces. Male and foreign workers were at greater risk of occupational injuries. The risk of serious or fatal accidents was reduced by greater work experience and was increased by working longer hours. Prevention would help to reduce the risk of accidents in temporary, male, private-sector and foreign workers. To reduce the incidence of serious and fatal accidents, the number of hours worked should be limited, especially in employees without extensive work experience.

Sexual orientation: its relevance to occupational science and the practice of occupational therapy.
Jackson, J
1995-01-01
This article examines how sexual orientation may be relevant to the study of occupations and the practice of occupational therapy. It is suggested that a lesbian, gay, or bisexual orientation may influence the occupations in which a person engages, the symbolic interpretation of those occupations, and the environmental contingencies of those occupations, and thus is an appropriate topic for occupational scientists to address. With the use of clinical reasoning studies and literature on authentic occupational therapy, it is argued that a person's lesbian, gay, or bisexual orientation may be relevant to the therapeutic process if therapists are to truly achieve an intersubjective understanding of the patient's world and create an environment in which the patient is able to live a meaningful life. Given this argument as a foundation, the article explores why sexual orientation may be overlooked in some of the theoretical perspectives that guide practice. The narrative perspective on identity is introduced as one potentially valuable way that occupational therapy researchers and practitioners may understand sexual orientation and its relationship to occupation. Specifically it is suggested that sexual orientation may be understood, in part, as a symbolic theme of meaning that informs values and convictions that may then be expressed in one's choice of occupations.

It is suspected that there is a large number of patients suffering from hand-arm vibration syndrome (HAVS) in Korea. However, no cases have been reported since 1992. This study was conducted to identify HAVS cases and determine the characteristics of the syndrome. In April 2001, the Busan, Ulsan, and Gyeong-Nam Province Occupational Disease Surveillance System (BUGODSS) was established to identify work-related HAVS and other occupational diseases. In the 2 years of this project, occupational physicians from five hospitals in these provinces collected information by way of interviews and questionnaires during mandatory occupational medical examinations. Among the initial 189 suspected HAVS cases, 58 volunteers were given cold-water provocation tests in order to diagnose the vascular component of the disorder. One hundred fifty-four approximately occupational HAVS cases were identified from ca. 21,000 workers. One hundred fifty about of these cases were male. The cases were most often found in workers from the shipbuilding industry, and the grinder was the most common source of vibration exposure. Cases of sensorineural disorder (SD) were more common than cases of vascular disorder (VD). The mean values of the finger skin temperature and its recovery rate at 5 min and 10 min after cold-water provocation were significantly lower in the group with the VD than in the group with the SD. We identified 154 occupational HAVS cases, although no cases have been reported during the occupational medical examinations mandated by the state. The majority of the cases were in workers that used grinders in the shipbuilding industry. We determined that peripheral VD and peripheral SD can progress independently of each other. We conclude that exposure to hand-transmitted vibration (HTV) and HAVS cases are common in shipbuilding industry in Korea. The recovery rate of finger skin temperature after cold-water provocation is one of the useful methods for diagnosing the vascular component

The association of body height with occupational success has been frequently studied, with previous research mainly finding a positive effect among men and positive or null effects among women. Occupational success has almost exclusively been measured so far by short-term success variables (e.g., annual income). In the present study, the relationship of success and height was examined in a group of actors and actresses using a large online database about movies (Internet Movie Database) where heights of actors and actresses are stated. The number of roles played in movies and television series during each actor's lifetime was used as a measure of long-term occupational success. No height effect was found for male actors but a significant negative effect was found for actresses, even after controlling for possible confounding influences (age and birth year). Compared to the general population, actors and actresses were significantly taller; however, actresses who were shorter than average were more likely to achieve greater occupational success, in terms of being featured in more movies.

The aim of this study was to establish a set of occupational safety and health (OSH) issues and development policies suitable for adoption in Taiwan. A survey was conducted on a sample of 102 experts and 235 industrial work safety personnel in Taiwan for statistical analysis of the general consensus, with the results showing such consensus in 104 individual policy indicators. Our results reveal that the most appropriate targets were considered to be annual 10% reductions in the 'occupational accident disability rate', 'occupational accident injury rate' and 'occupational diseases before 2010'. Responding to the specific question of the appropriate method of achieving a reduction in the number of accidents in Taiwan, the primary consideration for 13.4% of the experts and 10.6% of the industry personnel was 'promoting OSH awareness and enhancing the overall safety culture'. As regards the current OSH policy focus, 11.2% of the experts considered 'improving OSH legislation, standards and systems' to be the most important, whilst 8.9% of the industry personnel felt that 'recognizing work stress, overwork and emerging OSH issues' were the most important.

The occupational physician may play a crucial role in the risk assessment of workers in a given occupational environment. In fact, according to the current italian legislation, the document on risk assessment must be produced by the employer, with the cooperation of the responsible for prevention and safety and, in the due contexts, with the contribution of the occupational physician. Therefore, a cooperation between the different figures involved in the process is a pre-requisite for the elaboration of an adequate planning of preventive measures. From the point of view of the occupational physician, it seems necessary a preliminary in-depth knowledge of the plant and of the various steps of the productive process. In particular it is mandatory to have precise data on the number of workers, the mean age, work seniority, and the percentage of disabled workers. As a corollary, it is important to know the frequency of occupational related disorders, the number of accident at work, and the possible presence of contentious procedures with security organisms. Several important open questions remain, however: in particular to establish a causal relationship of any disorder with occupational situtations and to discriminate between distressing situations inside and outside the work environment.

The Effect of Personality on Occupational Stress in Veterinary Surgeons.
Dawson, Briony F Y; Thompson, Neill J
Statistics show that veterinary surgeons are in one of the professions with the highest suicide rates. This indicates the sector has significant well-being issues, with high levels of occupational stress and burnout. Previous research has focused on environmental factors in isolation, overlooking the influence of personality. This study aimed to establish that personality is a better predictor of occupational stress than environment. UK veterinary surgeons (n=311) completed an online survey composed of three questionnaires; the NEO Five-Factor Inventory, the Maslach Burnout Inventory, and the Job Stress Survey. Multiple regression analysis revealed that personality is a better predictor of occupational stress than environment (p<.001). Neuroticism is the trait that significantly predicts occupational stress (p<.001), and the components of neuroticism that contribute the most to stress are depression (p=.002) and anger hostility (p=.005). Demographic factors such as the number of years the veterinarian has been qualified acted as a mediator between depression and occupational stress (p<.001), and as a moderator between personal accomplishments and occupational stress (p=.028). Overall findings suggest that newly qualified veterinarians are at greater risk of suffering from high levels of occupational stress than those well established in the profession, and that veterinarians with higher levels of depression and anger hostility are likely to experience greater levels of occupational stress. Implications highlight the need for greater awareness of potentially susceptible personality traits in the veterinary admissions process. This would allow for the identification of those at risk and the implementation of interventions.

BACKGROUND: Specific inhalation challenges (SIC) enable the identification of the agent responsible of occupational asthma (OA). A clinician may fail to identify a specific agent in the workplace, which may potentially lead to a misdiagnosis. The expert assessment method performed by an occupational hygienist has been used to evaluate occupational exposures in epidemiological studies. OBJECTIVE: The broad aim of the present study was to evaluate the contribution of an expert assessment performed by an occupational hygienist to the diagnosis of OA. The specific aim was to compare work-place exposures identified by an occupational hygienist and by chest physicians in subjects with positive SICs and subjects with asthma, but with a negative SIC. METHODS: SICs were performed in 120 cases: 67 were positive and 53 were negative. A clinician assessed occupational exposures to sensitizers during a routine clinical evaluation preceding the performance of the SIC. An expert assessment of occupational exposures was performed by an occupational hygienist blind to the result of the SIC. RESULTS: The occupational hygienist identified the causal agent in 96.7% of the 61 cases of positive SIC. In 33 (62.3%) cases of negative SICs, the occupational hygienist identified ≥1 sensitizing agent(s) that had not been identified by the clinician. CONCLUSION: The hygienist identified the causal agent in almost all subjects with OA. In contrast, the clinician failed to identify potential exposures to sensitizers in >60% of the negative SIC subjects, which may have resulted in some subjects being misdiagnosed as not having OA.

2007-01-01
Road traffic injuries constitute one of the main causes of death and disability in Italy and in the European Union. Occupational medicine should pay special attention to the field of road transport because every year a large number of road accidents occur with fatal outcomes. Via health surveillance the occupational physician can play an important role in the prevention of such events. The aim of the article is to summarize the results of the most recent studies on the main risk factors for road transport safety and discuss possible strategies of health surveillance, according to the recent indications of the European Agency for Safety and Health at Work, Bilbao. A review of the literature was made. The scientific literature provides a large amount of interesting information on the most important risk factors for road accidents, such as drinking and drug abuse, sleepiness and other medical conditions, or excessive speed. The presence of numerous and varied hazards for road transport safety requires, as suggested by the Bilbao Agency, the adoption of occupational health measures, including risk assessment, health education, technical and environmental prevention, health surveillance and clinical interventions (diagnosis and rehabilitation of occupational accidents). Moreover, the paper stresses the need to strengthen collaboration between occupational health physicians and other medical specialists.

Ventilation requirements in buildings—I. Control of occupancy odor and tobacco smoke odor
NASA Astrophysics Data System (ADS)
Cain, William S.; Leaderer, Brian P.; Isseroff, Ruth; Berglund, Larry G.; Huey, Raymond J.; Lipsitt, Eric D.; Perlman, Dan
Psychophysical measurements of odor, supplemented with certain physical measurements, were taken to examine ventilation requirements during smoking and nonsmoking occupancy in an environmental chamber. The facility provided the means to compare impressions of visitors (persons who inhaled air from the chamber only briefly) with impressions of occupants. For nonsmoking occupancy, 47 combinations of temperature, humidity, ventilation rate and occupancy density were examined. Odor level depended entirely on ventilation rate per person irrespective of the number of persons in the chamber. The ventilation necessary to satisfy 75 % of visitors equalled only about 4 ℓ s -1 per person. Occupants, however, were satisfied with far less. In an array of 38 conditions of smoking occupancy, the ventilation deemed necessary to satisfy 75 % of visitors under customary conditions of occupancy equalled 17.5 ℓ s -1 per person. For both smoking and nonsmoking conditions, a combination of high temperature (25.5°C) and humidity (r.h. > 70 %) exacerbated the odor problem. During smoking, carbon monoxide rarely reached dangerous levels, but suspended particulate matter often reached levels considered unacceptable outdoors. The results highlight the energy penalty incurred in ventilation for smoking occupancy.

A Second Look at the Process of Occupational Feminization and Pay Reduction in Occupations.
Mandel, Hadas
2018-04-01
Using the IPUMS-USA data for the years 1960-2015, this study examines trends in the effect of occupational feminization on occupational pay in the U.S. labor market and explores some of the mechanisms underlying these trends. The findings show that the (negative) association between occupational feminization and occupational pay level has declined, becoming insignificent in 2015. This trend, however, is reversed after education is controlled for at the individual as well as the occupational level. The two opposite trends are discussed in light of the twofold effect of education: (1) the entry of women into occupations requiring high education, and (2) the growing returns to education and to occupations with higher educational requirements. These two processes have concealed the deterioration in occupational pay following feminization. The findings underscore the significance of structural forms of gender inequality in general, and occupational devaluation in particular.

Relationship of Occupational and Non-Occupational Stress with Smoking in Automotive Industry Workers
Hassani, Somayeh; Yazdanparast, Taraneh; Ghaffari, Mostafa; Attarchi, Mirsaeed; Bahadori, Baharak
2014-01-01
Background Tobacco use is the second cause of death and first cause of preventable mortality worldwide. Smoking in the workplace is particularly concerning. Smoking-free workplaces decrease the risk of exposure of non-smoking personnel to cigarette smoke. Recent studies have mostly focused on the effect of daily or non-occupational stressors (in comparison with occupational stress) on prevalence of smoking. Occupational stress is often evaluated in workplaces for smoking cessation or control programs, but the role of non-occupational stressors is often disregarded in this respect. Materials and Methods This cross-sectional study was conducted in an automobile manufacturing company. The response of automotive industry workers to parts of the validated, reliable, Farsi version of Musculoskeletal Intervention Center (MUSIC)-Norrtalje questionnaire was evaluated. A total of 3,536 factory workers participated in this study. Data were analyzed using SPSS and P<0.05 was considered statistically significant. Results The correlation of smoking with demographic factors, occupational stressors and life events was evaluated. The results of logistic regression analysis showed that even after adjusting for the confounding factors, cigarette smoking was significantly correlated with age, sex, level of education, job control and life events (P<0.05). Conclusion The results showed that of occupational and non-occupational stressors, only job control was correlated with cigarette smoking. Non-occupational stressors had greater effect on cigarette smoking. Consideration of both non-occupational and occupational stressors can enhance the success of smoking control programs. On the other hand, a combination of smoking control and stress (occupational and non-occupational) control programs can be more effective than smoking cessation interventions alone. PMID:25506374

This lecture presents an example of research in the genre of interpretive occupational science and demonstrates how occupational science can inform clinical practice. The innovative qualitative methodology used blended elements of the anthropological tradition of life history ethnography, ethnomethodology, the naturalistic methods used by Mattingly and Schön to study practice, and especially narrative analysis as described by Polkinghorne. The bulk of the paper is presented in the form of a narrative analysis that provides an account of a stroke survivor's personal struggle for recovery, a story that emerged from transcription, coding, and analysis of transcripts from approximately 20 hours of interview time. First, this narrative analysis provides an example of how the occupational science framework can evoke a particular kind of storytelling in which childhood occupation can be related to adult character. Storytelling of this kind is later shown to be therapeutic for the stroke survivor. Next, the narrative illustrates how rehabilitation can be experienced by the survivor as a rite of passage in which a person is moved to disability status and then abandoned. Finally, a picture is given of how occupational story making and occupational storytelling embedded in real life can nurture the human spirit to act and can become the core of clinical practice.

Occupational asthma: a review.
Lombardo, L J; Balmes, J R
2000-01-01
Occupational asthma is the most common form of occupational lung disease in the developed world at the present time. In this review, the epidemiology, pathogenesis/mechanisms, clinical presentations, management, and prevention of occupational asthma are discussed. The population attributable risk of asthma due to occupational exposures is considerable. Current understanding of the mechanisms by which many agents cause occupational asthma is limited, especially for low-molecular-weight sensitizers and irritants. The diagnosis of occupational asthma is generally established on the basis of a suggestive history of a temporal association between exposure and the onset of symptoms and objective evidence that these symptoms are related to airflow limitation. Early diagnosis, elimination of exposure to the responsible agent, and early use of inhaled steroids may play important roles in the prevention of long-term persistence of asthma. Persistent occupational asthma is often associated with substantial disability and consequent impacts on income and quality of life. Prevention of new cases is the best approach to reducing the burden of asthma attributable to occupational exposures. Future research needs are identified. PMID:10931788

This study sought to identify factors associated with occupational health staffing in health care settings, provide benchmarking data, and investigate relationships between staffing and worker stress and satisfaction. Members of the Association of Occupational Health Professionals in Healthcare were sent an online survey. Data on facility served, staffing, job attitudes, and work stress were collected and analyzed. Number and types of personnel served were the largest predictors of staffing, accounting for 38 and 41% of the variability seen, respectively. Number of personnel served was related to worker stress and lack of work/life balance. Offices that required a provider presence had roughly one provider, seven nurses, and three clerical staff per 8000 personnel served. Occupational health workers are generally highly satisfied, and staffing has little relation to sources of job stress and satisfaction.

[Occupational hazards and bladder cancer].
Nizamova, R S
1991-01-01
Occupational exposure to health hazards was studied in 258 industrial workers who had developed cancer of the bladder against 454 matched controls. All the test subjects and controls were residents of the Tambov Province centers of chemical industry. Statistical significance (relative risk-4.7) was established for exposure to aromatic amines. For those contacting with aniline dyes the relative risk (RR) made up 2.4. The risk to develop bladder cancer in powder shops (RR-3.2) was attributed to the hazards of dyes and diphenylamine. In leather-shoe and textile industry the exposure to dyes was not safe (RR-6.1), neither was it to chemicals, oil products, pesticides, overheating (RR-3.2, 1.6, 3.2 and 2.9, respectively). It is stated that in line with a significant risk to develop bladder cancer at exposure to aromatic amines there exist a number of occupational factors contributing to this risk.

The proportion of occupational infectious diseases (ID) in the total number of occupational diseases reported in the Slovak Republic (SR) and the Czech Republic (CR) was decreasing from 1973 to 2010. Our study presents a longitudinal analysis of the occurrence of occupational infectious diseases in the Slovak Republic and the Czech Republic in the period from 1973-2010 with special focus on viral hepatitis. The sources of data were national health statistics of Czechoslovakia, the Czech Republic and the Slovak Republic. Descriptive statistical methods were used for data analysis. Incidence rate of reported diseases was calculated per 100,000 general population or per 100,000 people insured. During the studied period, a total of 2,931 and 8,318 cases of occupational viral hepatitis (VH) were reported in the Slovak Republic and the Czech Republic, respectively. The incidence culminated in the late 1970s when hepatitis represented almost 50% of all reported occupational infectious diseases. Most cases of occupational hepatitis occurred in health and social services. Since the early 1980s, a steep decrease in the incidence of hepatitis has been observed due to the gradual implementation of mandatory vaccination against hepatitis A and B in risk groups. In SR in 1973, the incidence rate of occupational infectious diseases and that of occupational viral hepatitis was 10.85/100,000 and 1.86/100,000, respectively. In 2010, these rates decreased to 0.74/100,000 and 0.20/100,000, respectively. In CR, the incidence rates of occupational infectious diseases and that of occupational viral hepatitis reported in 1973 were 11.75/100,000 and 3.69/100,000. In 2010, reported incidence rates were 1.71/100,000 and 0.10/100,000, respectively. Although the incidence of occupational viral hepatitis has dramatically decreased in the Slovak and the Czech Republic as well as in other Visegrad group countries during the studied period, we emphasize the necessity of continuing epidemiological

Population Health and Occupational Therapy.
Braveman, Brent
2016-01-01
Occupational therapy practitioners play an important role in improving the health of populations through the development of occupational therapy interventions at the population level and through advocacy to address occupational participation and the multiple determinants of health. This article defines and explores population health as a concept and describes the appropriateness of occupational therapy practice in population health. Support of population health practice as evidenced in the official documents of the American Occupational Therapy Association and the relevance of population health for occupational therapy as a profession are reviewed. Recommendations and directions for the future are included related to celebration of the achievements of occupational therapy practitioners in the area of population health, changes to the Occupational Therapy Practice Framework and educational accreditation standards, and the importance of supporting, recognizing, rewarding, and valuing occupational therapy practitioners who assume roles in which direct care is not their primary function.

Individual and occupational factors related to fatal occupational injuries: a case-control study.
Villanueva, Vicent; Garcia, Ana M
2011-01-01
This study has been designed in order to identify factors increasing the risk of a fatal outcome when occupational accidents occur. The aim is to provide further evidence for the design and implementation of preventive measures in occupational settings. The Spanish Ministry of Labour registry of occupational injuries causing absence from work includes information on individual and occupational characteristics of injured workers and events. Registered fatal occupational injuries in 2001 (n=539) were compared to a sample of non-fatal injuries in the same year (n=3493). Risks for a fatal result of occupational injuries, adjusted by individual and occupational factors significantly associated, were obtained through logistic regression models. Compared to non-fatal injuries, fatal occupational injuries were mostly produced by trapping or by natural causes, mostly related to elevation and transport devices and power generators, and injured parts of body more frequently affected were head, multiple parts or internal organs. Adjusted analyses showed increased risk of fatality after an occupational injury for males (adjusted odds ratio aOR=10.92; 95%CI 4.80-24.84) and temporary workers (aOR=5.18; 95%CI 2.63-10.18), and the risk increased with age and with advancing hour of the work shift (p for trends <0.01). Injuries taking place out of the usual occupational setting (aOR=2.85, 95%CI 2.27-3.59), or carrying out atypical tasks (aOR=2.08; 95%CI 1.27-3.39) showed increased risks of a fatal result too, as occupational accidents in agricultural or construction companies. These data can help to select and define priorities for programmes aimed to prevent fatal consequences of occupational injuries. Copyright © 2010 Elsevier Ltd. All rights reserved.

The 45th Japanese Society of Occupational and Environmental Allergy (OEA) Annual Meeting 2014 was held in Fukuoka city in conjunction with a technical course for occupational health physicians to learn occupational and environmental diseases more deeply. Allergic reaction due to low concentrations of chemical and biological materials is important in toxicological diseases due to highly concentrated chemical materials in the field of occupational and environmental medicine. In this paper we describe the activities of the OEA, which was established in 1970 and has completely cured patients with severe occupational asthma, such as the regional Konjac asthma in Gunma prefecture and Sea Squirt asthma in Hiroshima prefecture. Regard for the occupational environment will prevent the onset and/or exacerbation of allergic occupational disease in individual employees with allergy. Occupational cancer of the bile duct and asbestosis are also current, serious issues that should be resolved as soon as possible. It is desirable for the occupational health physician to have a large stock of knowledge about toxicological and allergic diseases in various occupational settings to maintain the health and safety of workers.

High-risk occupations for suicide.
Roberts, S E; Jaremin, B; Lloyd, K
2013-06-01
High occupational suicide rates are often linked to easy occupational access to a method of suicide. This study aimed to compare suicide rates across all occupations in Britain, how they have changed over the past 30 years, and how they may vary by occupational socio-economic group. Method We used national occupational mortality statistics, census-based occupational populations and death inquiry files (for the years 1979-1980, 1982-1983 and 2001-2005). The main outcome measures were suicide rates per 100 000 population, percentage changes over time in suicide rates, standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs). Several occupations with the highest suicide rates (per 100 000 population) during 1979-1980 and 1982-1983, including veterinarians (ranked first), pharmacists (fourth), dentists (sixth), doctors (tenth) and farmers (thirteenth), have easy occupational access to a method of suicide (pharmaceuticals or guns). By 2001-2005, there had been large significant reductions in suicide rates for each of these occupations, so that none ranked in the top 30 occupations. Occupations with significant increases over time in suicide rates were all manual occupations whereas occupations with suicide rates that decreased were mainly professional or non-manual. Variation in suicide rates that was explained by socio-economic group almost doubled over time from 11.4% in 1979-1980 and 1982-1983 to 20.7% in 2001-2005. Socio-economic forces now seem to be a major determinant of high occupational suicide rates in Britain. As the increases in suicide rates among manual occupations occurred during a period of economic prosperity, carefully targeted suicide prevention initiatives could be beneficial.

Appraisal of levels and patterns of occupational exposure to 1,3-butadiene.
Scarselli, Alberto; Corfiati, Marisa; Di Marzi, Davide; Iavicoli, Sergio
2017-09-01
Objectives 1,3-butadiene is classified as carcinogenic to human by inhalation and the association with leukemia has been observed in several epidemiological studies. The aim of this study was to evaluate data about occupational exposure levels to 1,3-butadiene in the Italian working force. Methods Airborne concentrations of 1,3-butadiene were extracted from the Italian database on occupational exposure to carcinogens in the period 1996-2015. Descriptive statistics were calculated for exposure-related variables. An analysis through linear mixed model was performed to determine factors influencing the exposure level. The probability of exceeding the exposure limit was predicted using a mixed-effects logistic model. Concurrent exposures with other occupational carcinogens were investigated using the two-step cluster analysis. Results The total number of exposure measurements selected was 23 885, with an overall arithmetic mean of 0.12 mg/m3. The economic sector with the highest number of measurements was manufacturing of chemicals (18 744). The most predictive variables of the exposure level resulted to be the occupational group and its interaction with the measurement year. The highest likelihood of exceeding the exposure limit was found in the manufacture of coke and refined petroleum products. Concurrent exposures were frequently detected, mainly with benzene, acrylonitrile and ethylene dichloride, and three main clusters were identified. Conclusions Exposure to 1,3-butadiene occurs in a wide variety of activity sectors and occupational groups. The use of several statistical analysis methods applied to occupational exposure databases can help to identify exposure situations at high risk for workers' health and better target preventive interventions and research projects.

To determine which specific groups of occupational stress factors influence the duration of temporary work disability related to arterial hypertension and joint complications/co-morbidities. Workers (n = 1398; 1009 in the exposed group, 389 in the control group) with arterial hypertension who worked at one workplace for a minimum of 10 years were divided into 10 subgroups, depending on the presence of joint complications/co-morbidities. The intensity of seven groups of occupational stress factors, the total score of Occupational Stress Index (OSI) and the average number of lost working days during 1 year were analysed. The number of lost working days due to arterial hypertension and joint complications/co-morbidities was significantly higher in the exposed group. In all subgroups of the exposed group there was a high correlation between the number of lost working days and the total OSI score. Specific occupational stress factors were associated with specific complications: High Demands with chronic myocardial infarction, Strictness with cerebral haemorrhage, Conflict/Uncertainty with cerebral infarction, Extrinsic Time Pressure with acute myocardial infarction, and Avoidance/Symbolic Aversiveness with non-insulin-dependent diabetes. There are specific groups of occupational stress factors which can influence the duration of work disability associated with certain complications and co-morbidities of arterial hypertension.

Occupational stress and burnout of judges and procurators.
Tsai, Feng-Jen; Chan, Chang-Chuan
2010-02-01
This study aims to examine the associations between occupational stress and burnout among judges and procurators. The Chinese versions of the job content questionnaire (JCQ), Siegrist's effort-reward imbalance questionnaire (ERI), and the Copenhagen Burnout Inventory (CBI) were administered to examine occupational stress and personal, work-related, and client-related burnout among 211 judicial officers, comprising 87 judges and 98 procurators, in Taiwan. Logistic regression was applied to determine the association between burnout and occupational stress among judges and procurators, adjusting for potential confounders of age, gender, marriage, number of children, work experience, working hours, and the significant occupational stress scale of each model for the other. The judicial officers with average age of 36.84 years and work experience of 8.57 years had high averaging scores of job control (70.31), psychological demand (32.23), effort (18.98), reward (48.37), and overcommitment (17.04) as well as personal (49.97), work-related (51.36), and client-related (43.57) burnout. The high psychological demand, effort, and overcommitment were significantly associated with both personal and work-related burnout, while the low workplace social support was significantly associated with client-related burnout among the judicial officers. The judges had a significant higher risk of client-related burnout than the procurators. In general, occupational stress was associated with personal and work-related burnout for both judges and prosecutors. Client-related burnout was more common for judicial officers with low social support and the judges.

Parental occupational exposures and risk of childhood cancer.
Colt, J S; Blair, A
1998-01-01
Occupational exposures of parents might be related to cancer in their offspring. Forty-eight published studies on this topic have reported relative risks for over 1000 specific occupation/cancer combinations. Virtually all of the studies employed the case-control design. Occupations and exposures of fathers were investigated much more frequently than those of the mother. Information about parental occupations was derived through interviews or from birth certificates and other administrative records. Specific exposures were typically estimated by industrial hygienists or were self-reported. The studies have several limitations related to the quality of the exposure assessment, small numbers of exposed cases, multiple comparisons, and possible bias toward the reporting of positive results. Despite these limitations, they provide evidence that certain parental exposures may be harmful to children and deserve further study. The strongest evidence is for childhood leukemia and paternal exposure to solvents, paints, and employment in motor vehicle-related occupations; and childhood nervous system cancers and paternal exposure to paints. To more clearly evaluate the importance of these and other exposures in future investigations, we need improvements in four areas: a) more careful attention must be paid to maternal exposures; b) studies should employ more sophisticated exposure assessment techniques; c) careful attention must be paid to the postulated mechanism, timing, and route of exposure; and d) if postnatal exposures are evaluated, studies should provide evidence that the exposure is actually transferred from the workplace to the child's environment.

The nervous system is vulnerable to the effects of certain chemicals and physical conditions found in the work environment. The activities of an occupational neurologist focus on the evaluation of patients with neurological disorders caused by occupational or environmental conditions. When one is making a differential diagnosis in patients with neurological disorders, the possibility of toxic exposure or encounters with physical factors in the workplace must not be overlooked. Central to an accurate clinical diagnosis is the patient's history. A diagnosis of an occupational or environmental neurological problem requires a careful assessment of the clinical abnormalities and confirmation of these disabilities by objective tests such as nerve conduction velocity, evoked potentials, electroencephalogram, neuropsychological batteries, or nerve biopsy. On the basis of information about hazards in the workplace, safety standards and environmental and biological monitoring can be implemented in the workplace to reduce the risks of undue injury. Clinical manifestations of headache, memory disturbance, and peripheral neuropathy are commonly encountered presentations of the effects of occupational hazards. Physicians in everyday clinical practice must be aware of the signs and symptoms associated with exposure to possible neurotoxins and work methods. Occupational and environmental circumstances must be explored when evaluating patients with neurologic disorders. PMID:3577214

Occupational exposure limits have traditionally focused on preventing morbidity and mortality arising from inhalation exposures to individual chemical stressors in the workplace. While central to occupational risk assessment, occupational exposure limits have limited application as a refined disease prevention tool because they do not account for all of the complexities of the work and non-occupational environments and are based on varying health endpoints. To be of greater utility, occupational exposure limits and other risk management tools could integrate broader consideration of risks from multiple exposure pathways and routes (aggregate risk) as well as the combined risk from exposure to both chemical and non-chemical stressors, within and beyond the workplace, including the possibility that such exposures may cause interactions or modify the toxic effects observed (cumulative risk). Although still at a rudimentary stage in many cases, a variety of methods and tools have been developed or are being used in allied risk assessment fields to incorporate such considerations in the risk assessment process. These approaches, which are collectively referred to as cumulative risk assessment, have potential to be adapted or modified for occupational scenarios and provide a tangible path forward for occupational risk assessment. Accounting for complex exposures in the workplace and the broader risks faced by the individual also requires a more complete consideration of the composite effects of occupational and non-occupational risk factors to fully assess and manage worker health problems. Barriers to integrating these different factors remain, but new and ongoing community-based and worker health-related initiatives may provide mechanisms for identifying and integrating risk from aggregate exposures and cumulative risks from all relevant sources, be they occupational or non-occupational.

The Impact of Language and Culture Diversity in Occupational Safety.
De Jesus-Rivas, Mayra; Conlon, Helen Acree; Burns, Candace
2016-01-01
Occupational health nursing plays a critical part in improving the safety of foreign labor workers. The development and implementation of safety training programs do not always regularly take into account language barriers, low literacy levels, or cultural elements. This oversight can lead to more injuries and fatalities among this group. Despite established health and safety training programs, a significant number of non-native English speakers are injured or killed in preventable, occupation-related accidents. Introducing safety programs that use alternative teaching strategies such as pictograms, illustrations, and hands-on training opportunities will assist in addressing challenges for non-English laborers. Occupational health nursing has an opportunity to provide guidance on this subject and assist businesses in creating a safer and more productive work environment. © 2015 The Author(s).

Occupational fatalities in Jordan.
Al-Abdallat, Emad M; Oqailan, Ahmad Mohammad A; Al Ali, Rayyan; Hudaib, Arwa A; Salameh, Ghada A M
2015-01-01
Occupational fatalities are a worldwide problem. Certain occupations pose a greater risk than others. Recent statistics on global occupational injuries and diseases that might lead to temporary or permanent disability and even worse might lead to death, are staggering. The purpose of this study was to estimate the death rates from occupational injuries in Jordan over a period of four years; to estimate occupational fatality rate that results from accidental injuries and identify the most risky concurrent occupations with the type of injuries, the age and nationality of the victims. A total of 88 work related fatalities were admitted to three hospitals in Amman through 2008-2012 and were examined by a forensic (occupational) physician at the time. They were categorized according to, age, nationality, occupation, type of injury and were all tested for toxic substances. The occupation with the most fatalities was construction (44%); falling from a height was the commonest type of accident (44%) and head injuries were the leading injury type (21.6%); 9.1% of the deaths were positive for alcohol. Moreover, 22.7% of deaths were between ages of 25-29. Consequently, the mean occupational fatality rate was 2 per 100.000 workers during 2008-2012. Constructions and other types of occupations are more extensive problems than what is usually anticipated, especially when safety precautions are not effective or implemented. They may cause injuries and death, which will have a socioeconomic burden on families, society, governments and industries. Not to mention the grief that is associated with the death of a worker at his work site to all concerned parties. Copyright © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

High mammographic density is one of the main risk factors for breast cancer. Although several occupations have been associated with breast cancer, there are no previous occupational studies exploring the association with mammographic density. Our objective was to identify occupations associated with high mammographic density in Spanish female workers. We conducted a population-based cross-sectional study of occupational determinants of high mammographic density in Spain, based on 1476 women, aged 45-68 years, recruited from seven screening centers within the Spanish Breast Cancer Screening Program network. Reproductive, family, personal, and occupational history data were collected. The latest occupation of each woman was collected and coded according to the 1994 National Classification of Occupations. Mammographic density was assessed from the cranio-caudal mammogram of the left breast using a semi-automated computer-assisted tool. Association between mammographic density and occupation was evaluated by using mixed linear regression models, using log-transformed percentage of mammographic density as dependent variable. Models were adjusted for age, body mass index, menopausal status, parity, smoking, alcohol intake, educational level, type of mammography, first-degree relative with breast cancer, and hormonal replacement therapy use. Screening center and professional reader were included as random effects terms. Mammographic density was higher, although non-statistically significant, among secondary school teachers (e β = 1.41; 95%CI = 0.98-2.03) and nurses (e β = 1.23; 95%CI = 0.96-1.59), whereas workers engaged in the care of people (e β = 0.81; 95%CI = 0.66-1.00) and housewives (e β = 0.87; 95%CI = 0.79-0.95) showed an inverse association with mammographic density. A positive trend for every 5 years working as secondary school teachers was also detected (p-value = 0.035). Nurses and secondary school teachers were the occupations with the highest

The construction industry produces the highest number of occupational injuries in Spain (25.6%). Of these, 98.5% were minor injuries with 5 million workdays lost in 2000. This occurred even after the recent introduction of numerous health and occupational safety regulations. The objective of the present study was to identify the specific mechanisms of minor occupational injuries in the construction sector. In 2000, there were 235,853 minor occupational injuries in the construction industry. From these, injuries in general construction and civil engineering were selected (n = 155,044). These injuries affected both the total number of workers in the sector as well as bricklayers and unskilled construction workers. Insurance and financial activities (n = 2,019) were selected as a reference economic sector. Minor occupational injuries due to nontraumatic processes (heart attack, etc.) were taken as a control group (n = 167), assuming that the risk of nontraumatic processes was independent of economic activities. Odds ratios (OR) were adjusted by age, sex, years of work experience, type of employment and company size through nonconditional logistic regression models. The mechanisms with the highest risk of minor occupational lesions in construction workers as a group compared with employees in the financial sector were projection of fragments (OR = 33.0; 95% CI, 15.3-70.8) and being struck by objects (OR = 18.2; CI 95%, 9.7-34.1). These were also the most specific mechanisms of injury in the subgroup of bricklayers and unskilled construction workers. Activities aimed at preventing minor occupational injuries in the construction sector should be orientated towards these mechanisms, especially projection of fragments despite the low frequency of this mechanism compared with that of other mechanisms. Case-control design is a useful alternative approach for research into occupational injuries.

The aim was to (i) assess the outcomes of the 16-week Redesigning Daily Occupations (ReDO) programme for women on sick leave due to stress-related disorders, in terms of occupational value, satisfaction with everyday occupations, and participation level; (ii) investigate the relationships between those outcomes and return-to-work rate. A total of 42 women receiving ReDO and 42 receiving care as usual (CAU) were included in a matched-control study with measurements before and after the rehabilitation. Seventy-eight participated on both occasions. They completed self-report questionnaires regarding the aforementioned outcomes. Return-to-work data were obtained from the registers of the Social Insurance Offices. Increases in concrete, symbolic, and self-reward values were found in both groups, but no statistically significant difference between the groups was demonstrated. The ReDO group improved more than the CAU group, however, on satisfaction with everyday occupations and participation level. Occupational value, but not satisfaction with everyday occupations, was related to return to work. Everyday occupations were shown to be relevant outcomes after work rehabilitation. They could play an important role in future development of profession-specific evidence of occupational therapy. Further support was obtained for viewing occupational value and satisfaction with everyday occupations as theoretically distinct phenomena.

The Occupational Disease Surveillance System (ODSS) was established in Ontario, Canada by linking a cohort of workers with data created from Workplace Safety and Insurance Board (WSIB) claims to administrative health databases. The aim of this study was to use ODSS to identify high-risk industry and occupation groups for lung cancer in Ontario. Workers in the WSIB lost time claims database were linked to the Ontario Cancer Registry using subjects' health insurance numbers, name, sex, birthdate and death date (if applicable). Several occupations and industries known to be at increased risk were outlined a priori to examine whether ODSS could replicate these associations. Age-adjusted, sex-stratified Cox proportional hazard models compared the risk of lung cancer within one industry/occupation versus all other groups in the cohort. Workers with a lung cancer diagnosis prior to cohort entry were excluded for analysis, leaving 2 187 762 workers for analysis. During the 1983 to 2014 follow-up, 34 661 workers in the cohort were diagnosed with lung cancer. Among expected high-risk industries, elevated risks were observed among workers in quarries/sand pits and construction industries for both sexes, and among males in metal mines, iron foundries, non-metallic mineral products industries and transportation industries. Excess risk was also observed among occupations in drilling/blasting, other mining/quarrying, mineral ore treating, excavating/grading/paving, truck driving, painting, bus driving and construction. This current surveillance system identified several established high-risk groups for lung cancer and could be used for ongoing surveillance of occupational lung cancer in Ontario. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

In this lecture, I have reviewed theoretical discussions and definitions of occupational balance, findings from selected studies, and highlighted some methods for measuring aspects of occupational balance. Are any of these ideas directly applicable to occupational therapy practice, education and research? Consider the hassles of everyday life, and add the complicating factors of illness, injury, disability, and limited income. Life, and the pursuit of necessary, desirable and obligatory occupations, can become overwhelming. Given that occupational therapists aim to enable individuals, regardless of ability, to successfully engage in a range of occupations, the answer to the question is yes. Furthering our understanding of occupational balance can improve our ability to serve individual clients and society. In 2001, Fearing stated in her Muriel Driver Memorial Lecture: We will not only recognize and value the skill of maintaining balance, our own and that of our clients, but we will live it. Balance will not be viewed as a set of scales that has equal parts such as work on one side and play on the other but rather the kind of balance that comes from being centred so that we act from a stable base. From that stable base, we will gain a keen sensitivity to rhythm--knowing when to move and when to let go. (Fearing, 2001 pp. 214-215) Perhaps these reflections have added a little coherence to the study of occupational balance. Occupational balance is a relative state, recognizable by a happy or pleasant integration of life activities and demands. There are indicators of imbalance, more so than tangible ways to measure it, and once recognized occupational therapists have the strategies to help restore a sense of occupational balance. Given our collective history and skill in client-centred practice, occupational therapists are capable of both advancing this line of inquiry and attaining occupational balance for ourselves and our clients.

The purpose of this study was to assess the effectiveness of a client-centred, occupation-based occupational therapy programme for individuals with psychiatric diagnoses. The study took place in a college campus. A pre-test/post-test design was used. There were 38 participants which included college students and community members who desired to attend college, work and/or address life skill goals. The Canadian Occupational Performance Measure (COPM) was used as a pre- and post-test measure. Goals were based on problems identified in the COPM, reflected academic, vocational, life skill, and leisure goals, and were systematically addressed weekly through activities developed by the participant and a graduate occupational therapy student who acted as a mentor. The Participant Overall Satisfaction Scale was completed by each participant. A case study was used to describe the programme in more depth. The results support that the client-centred, occupation-based occupational therapy programme increased client scores on satisfaction and performance of occupational performance problems identified on the COPM. Further research is recommended to explore how client-centred occupational therapy programmes can be effective in improving academic, vocational and life skill goals.

Occupational lung diseases and the mining industry in Mongolia
DOE Office of Scientific and Technical Information (OSTI.GOV)
Lkhasuren, O.; Takahashi, K.; Dash-Onolt, L.
Mining production has accounted for around 50% of the gross industrial product in Mongolia since 1998. Dust-induced chronic bronchitis and pneumoconiosis currently account for the largest relative share (67.8%) of occupational diseases in Mongolia, and cases are increasing annually. In 1967-2004, medically diagnosed cases of occupational diseases in Mongolia numbered 7,600. Of these, 5,154 were confirmed cases of dust-induced chronic bronchitis and pneumoconiosis. Lung diseases and other mining-sector health risks pose major challenges for Mongolia. Gold and coal mines, both formal and informal, contribute significantly to economic growth, but the prevalence of occupational lung diseases is high and access tomore » health care is limited. Rapid implementation of an effective national program of silicosis elimination and pneumoconiosis reduction is critical to ensure the health and safety of workers in this important sector of the Mongolian economy.« less

[Occupational exposure to hand-transmitted vibration in Poland].
Harazin, Barbara; Zieliński, Grzegorz
2004-01-01
Occupational exposure to hand transmitted vibration may cause disorders in upper extremities known as hand-arm vibration syndrome. Therefore it is essential to know the sources of vibration, occupational groups exposed to vibration and the number of exposed workers. The aim of the study was to estimate the number of men and women exposed to hand-transmitted vibration in Poland. The completed questionnaires were obtained from 265 (80%) sanitary inspection stations. They included questions on: the name of workplaces, the name and the type of vibration sources, workers' gender, the number of workers exposed to vibration, indicating the extent of exposure measured against the three threshold limit values (< 0.5 TLV; 0.5 < TLV < 1 and > 1 TLV), and the number of workers exposed to hand-transmitted vibration not documented by measurements in a particular workplaces, indicating one of the three possible kinds of exposure (occasional, periodical and constant). The questionnaire data were based on measurements and analyses performed in 1997-2000. The results of the study showed that vibrating tools used by grinders, fitters, locksmiths, rammers, road workers, carpenters and smiths proved to be the most frequent sources of hand-transmitted vibration. It was revealed that 78.6% of operators of these tools were exposed to vibration exceeding 1 TLV. The study also indicated that 17,000 workers, including 1700 women, were exposed to vibration exceeding the threshold limit values.

[Some occupational determinants of work disability].
Szubert, Z; Sobala, W
1999-01-01
Occupational determinants play a significant role in the studies of the causes of work disability. The duration of employment is that particular variable, frequently analysed, which reflects indirectly the effect of work conditions on the worker's health state and also on his her disease-related work disability. Therefore, the aim of this work was to show the difference in sick absenteeism between various occupational groups, depending on the duration of employment. The empirical material embraced data on work disability, among workers employed in the automative industry plant during the years 1989-94. Out of 8,599 persons covered with the study, 77% left the job, including 7% of those who left the job because of health problems. An analysis of the impact of occupational determinants on the sick absenteeism was carried out on the basis of the absenteeism rate adjusted by age, sex and occupational activity in groups of the production, auxilliary and administrative workers, as well as in occupational groups exposed to possibly similar harmful factors. The duration of worker's employment in the plant showed a positive influence on sick absenteeism, since together with extended period of employment the decrease in the rate of general sick absenteeism was observed. However, in a number of disease categories an increase in absenteeism together with extended duration of employment, and a high level of absenteeism among workers involved directly in the production, were noted. This proves an adverse effect of work conditions on work disability among workers. The effect of harmful factors present at workposts is also confirmed by the increasing sick absenteeism together with the prolonged duration of employment in various occupational groups. In the group of welders the highest level of sick absenteeism was observed among persons with duration of employment ranging from 11 to 20 years (rate: 10.52), and it was related to diseases of the respiratory (3.10) and circulatory (2

Allergic and non-allergic rhinitis ranks among the common occupational health problems. However, data on the incidence of occupational rhinitis are lacking, since comprehensive studies are rare. The study includes a group of patients in the Slovak Republic who were reported as having occupational rhinitis in the years 1990-2011. The following parameters were tracked in the investigated sample: age, gender, number of cases by individual years, occupations, causative factors and the length of exposure to the given agent. Possible progression of rhinitis to bronchial asthma was evaluated as well. The diagnostic algorithm was also analysed retrospectively, which included skin tests, the examination of specific IgE antibodies and nasal provocation tests. A total of 70 cases of occupational rhinitis were reported. The disease most often occurred in food industry workers (50% of cases). The most common aetiological factor was flour. Among other relatively common allergens were synthetic textile, wool, cotton and different types of moulds. Significant agents were also different chemical factors causing allergic and irritant rhinitis. The average length of exposure was 14.8 years. Exposure was shorter in men than in women (11 years vs. 16 years) (p = 0.04). Bronchial asthma as a comorbidity was diagnosed in 13 patients (19.7%). The critical diagnostic method on the basis of which the causal association between rhinitis and work environments was confirmed in 59% of cases was skin test; confirmation of the occupational cause using nasal provocation test was less frequent (18%). Food industry, textile industry and agriculture were the most risky occupational environments. Workers in these sectors require preventive intervention. In case of showing rhinitis symptoms it is necessary to confirm the occupational aetiology of the disease by the objective diagnostic methods. Since occupational rhinitis mostly precedes the occupational asthma, the elimination from the workplace is

Absence from work due to occupational and non-occupational accidents.
Jørgensen, Kirsten; Laursen, Bjarne
2013-02-01
The aim of the present study was to investigate absence from work in Denmark due to occupational and non-occupational accidents. Since the beginning of the last decade, political focus has been placed on the population's working capacity and the scope of absence due to illness. Absence from work is estimated at between 3% and 6% of working hours in the EU and costs are estimated at approximately 2.5% of GNP. Victims of accidents treated at two emergency departments were interviewed regarding absence for the injured, the family and others. All answers were linked to the hospital information on the injury, so that it was possible to examine the relation between absence and injury type, and cause of the accident. In total, 1,479 injured persons were interviewed. 36% of these reported absence from work by themselves or others. In mean, an injury caused 3.21 days of absence. Based on this the total absence due to injuries in Denmark was estimated to 1,822,000 workdays, corresponding to approximately 6% of the total absence from work due to all types of illness. Non-occupational injuries resulted in more absence than did occupational injuries. Absence due to accidents contributed to a considerable part of the total absence from work, and non-occupational accidents caused more absence than did occupational accidents.

Deaths due to occupational disease and injury place a heavy burden on society in terms of economic costs and human suffering. We estimate the annual deaths due to selected diseases for which an occupational association is reasonably well established and quantifiable, by calculation of attributable fractions (AFs), with full documentation; the deaths due to occupational injury are then added to derive an estimated number of annual deaths due to occupation. Using 1997 US mortality data, the estimated annual burden of occupational disease mortality resulting from selected respiratory diseases, cancers, cardiovascular disease, chronic renal failure, and hepatitis is 49,000, with a range from 26,000 to 72,000. The Bureau of Labor Statistics estimates there are about 6,200 work-related injury deaths annually. Adding disease and injury data, we estimate that there are a total of 55,200 US deaths annually resulting from occupational disease or injury (range 32,200-78,200). Our estimate is in the range reported by previous investigators, although we have restricted ourselves more than others to only those diseases with well-established occupational etiology, biasing our estimates conservatively. The underlying assumptions and data used to generate the estimates are well documented, so our estimates may be updated as new data emerges on occupational risks and exposed populations, providing an advantage over previous studies. We estimate that occupational deaths are the 8th leading cause of death in the US, after diabetes (64,751) but ahead of suicide (30,575), and greater than the annual number of motor vehicle deaths per year (43,501).

Background Recent findings indicate that vitamin D obtained from ultraviolet (UV) exposure may reduce the risk of a number of different cancers. Vitamin D is metabolized to its active form within the kidney, the major organ for vitamin D metabolism and activity. Since both the incidence of renal cell cancer and prevalence of vitamin D deficiency have increased over the past few decades, this study sought to explore whether occupational UV exposure was associated with renal cell carcinoma (RCC) risk. Methods A hospital-based case-control study of 1,097 RCC cases and 1,476 controls was conducted in four Central and Eastern European countries. Demographic and occupational information was collected to examine the association between occupational UV exposure and RCC risk. Results A significant (24%-38%) reduction in RCC risk was observed with increasing occupational UV exposure among male participants. No association between UV exposure and RCC risk was observed among female participants. When analyses were stratified by latitude as another estimate of sunlight intensity, a stronger (71%-73%) reduction in RCC risk was observed between UV exposure and cancer risk among males residing at the highest latitudes. Conclusion The results of this study suggest that among males there is an inverse association between occupational UV exposure and renal cancer risk. Replication studies are warranted to confirm these results. PMID:20213683

Sickness absence in female- and male-dominated occupations and workplaces.
Mastekaasa, Arne
2005-05-01
Previous research suggests that both men's and women's level of sickness absence may be systematically related to the gender composition of their workplace as well as of their occupational category. The number of studies is, however, low and the composition of the occupational category has often been used as a proxy for the composition of the workplace. This paper employs a large data set broadly representative of the employed population of Norway. The data make it possible to take workplace and occupation simultaneously into account. Thus, the relationship between the gender composition of the workplace and sickness absence is estimated with detailed control for differences between occupational categories. Likewise, the importance of the gender composition of the occupation is assessed with control for between workplace variation. Men's sickness absence turns out to be largely unrelated to the gender composition of the workplace. For women the level of sickness absence tends to be higher in female-dominated workplaces, but the relationship is weak. These findings provide evidence against theories suggesting that the minority sex in the workplace faces special problems and is therefore more absent. They are to some extent consistent with the idea that female-dominated workplaces develop norms that are more tolerant towards sickness absence. The relationship of sickness absence to the gender composition of the occupational category is similar to the U-shaped pattern found in several previous studies (highest sickness absence both in strongly male-dominated and strongly female-dominated occupations), but again the relationship is weak.

This research examined the transition from occupational therapy student to practicing occupational therapist over the course of one's first year of professional employment, as recalled by a sample of occupational therapists. Surveys were mailed to 500 occupational therapists randomly selected from membership in the American Occupational Therapy Association resulting in 202 returned surveys. Median year of graduation was 1998, ranging from 1967 to 2014. In general, respondents indicated the transition was positive. Having a mentor was related to high job satisfaction and good clinical fit, while supervising an occupational therapy assistant and low self-confidence were viewed as negative impact factors. Recent graduates presented with lower ratings of a positive transition and higher ratings of likelihood of experiencing burnout and initial job stress than earlier graduates. Recommendations for improving the transition experience are presented.

Smoking cessation programs in occupational settings
Danaher, Brian G.
1980-01-01
For reasons of health and economics, the business community is displaying a growing interest in providing smoking cessation programs for employees. An examination of the current research on smoking cessation methods has revealed a number of promising directions that smoking cessation programs can take, for example, aversive smoking approaches combined with self-control strategies. A review of current smoking cessation programs in occupational settings revealed some emphasis on physician counseling, but a relatively greater emphasis on use of consultants (especially in proprietary programs) or of contingency programs to encourage nonsmoking. The smoking cessation programs in businesses can move in a number of innovative directions, including (a) increased use of inhouse programs with a variety of smoking cessation strategies; (b) greater emphasis on the training of program participants in nonsmoking behavioral skills, combined with contingency or incentive programs for smoking control; (c) vastly improved research methods, including complete followup assessments of program participants and chemical tests to validate their self-reported abstinence; (d) greater concern about the need for empirically tested procedures for recruitment of participants for the programs; and (e) expanded interchange among behavioral scientists (especially behavioral psychologists), health professionals in occupational health and medicine, union and employee groups, and management.

Purpose This study creates a more concise picture of the vocal demands placed on teachers by comparing occupational voice use with non-occupational voice use. Methods The National Center for Voice and Speech voice dosimetry databank was used to calculate voicing percentage per hour, as well as average dB SPL and F0. Occupational voice use (9am-3 PM, weekdays) and non-occupational voice use (4 PM-10 PM, weekends) were compared (57 teachers, two weeks each). Results Five key findings were uncovered: [1] similar to previous studies, occupational voicing percentage per hour is more than twice that of non-occupational; [2] teachers experienced a wide range of occupational voicing percentages per hour (30±11%/hr); [3] average occupational voice was about 1 dB SPL louder than the non-occupational voice and remained constant throughout the day; [4] occupational voice exhibited an increased pitch and trended upward throughout the day; [5] some apparent gender differences were shown. Conclusions Data regarding voicing percentages, F0 and dB SPL provide critical insight into teachers’ vocal health. Further, because non-occupational voice use is added to an already overloaded voice, it may add key insights into recovery patterns, and should be the focus of future studies. PMID:20689046

Epoxy-based production of wind turbine rotor blades: occupational dermatoses.
Pontén, A; Carstensen, O; Rasmussen, K; Gruvberger, B; Isaksson, M; Bruze, M
2004-06-01
Occupational dermatoses were investigated in a factory producing rotor blades for wind turbines by an epoxy-based process. In a blinded study design, 603 workers were first interviewed and thereafter clinically examined. Based on a history of work-related skin disease, clinical findings of dermatitis, or both, 325 (53.9%) of the workers were patch tested with a specially profiled occupational patch-test series and the European standard patch-test series. Calculated on all investigated workers, 17.1% of the workers were diagnosed with occupational dermatoses caused by work. Occupational allergic contact dermatitis was found in 10.9% of the workers. The estimated frequency of irritant contact dermatitis caused by work was 6.1%. Dermatitis on the hands was associated with contact allergy to epoxy resin (P = 0.017). The number of days on leave before the clinical examination was negatively associated with the presence of dermatitis (P = 0.001). Among workers employed 7-12 months, the frequency of occupational contact allergy was higher than that among workers employed for

Highly automated vehicle occupants will all be passengers and may be free to ride while in postures for which existing occupant safety systems such as seat belts and airbags were not originally designed. These occupants could therefore face increased risk of injury when a crash occurs. Given that current vehicles are capable of supporting a variety of occupant postures outside of the normal design position, such as reclined or turned passengers, an evaluation of current field data was performed to better understand the risks of being out of position. We investigated the frequency, demographics, and injury outcomes for out-of-position occupants using NASS-CDS. A matched analysis was performed to compare injury outcomes for out-of-position passengers with in-position drivers involved in similar crashes. Finally, case studies for out-of-position occupants were examined in the Crash Injury Research (CIREN) database. Only 0.5% of occupants in NASS-CDS with a coded posture were out of position at the time of crash. Of the out-of-position occupants, being turned or seated sideways was almost as likely as being reclined. Out-of-position occupants were younger and less likely to be belted than their in-position counterparts. Analysis of the injury data indicated a trend that being out of position was associated with an elevated risk for serious injury. However, the number of out-of-position occupants was too small to provide a definitive or statistically significant conclusion on injury outcome. Though highly automated vehicles may eventually reduce the number of crashes and traffic fatalities in the future, there will be a transition period when these vehicles remain at risk from collisions with human-driven vehicles. These crashes could cause higher than anticipated rates of injury if occupants are less likely to be belted or tend to be in positions for which restraints are not optimized. This study highlights the need for future research on occupant response and

[Occupational asthma in Hungary].
Endre, László
2015-05-10
Occupational asthma belongs to communicable diseases, which should be reported in Hungary. During a 24-year period between January 1990 and December 2013, 180 occupational asthma cases were reported in Hungary (52 cases between 1990 and 1995, 83 cases between 1996 and 2000, 40 cases between 2001 and 2006, and 5 cases between 2007 and 2013). These data are unusual, because according to the official report of the National Korányi Pulmonology Institute in Budapest, at least 14,000 new adult asthma cases were reported in every year between 2000 and 2012 in Hungary. Also, international data indicate that at least 2% of adult patients with asthma have occupational asthma and at least 50 out of 1 million employees develop occupational asthma in each year. In 2003, 631 new occupational asthma patients were reported in the United Kingdom, but only 7 cases in Hungary. Because it is unlikely that the occupational environment in Hungary is much better than anywhere else in the world, it seems that not all new occupational asthma cases are reported in Hungary. Of the 180 reported cases in Hungary, 55 were bakers or other workers in flour mills. There were 11 metal-workers, 10 health care assistants, 9 workers dealing with textiles (tailors, dressmakers, workers in textile industry) and 9 employees worked upon leather and animal fur. According to international data, the most unsafe profession is the animal keeper in scientific laboratories, but only 4 of them were reported as having occupational asthma during the studied 24 years in Hungary. Interestingly, 3 museologists with newly-diagnosed occupational asthma were reported in 2003, but not such cases occurred before or after that year. In this paper the Hungarian literature of occupational asthma is summarized, followed by a review on the classification, pathomechanism, clinical presentation, predisposing factors, diagnostics and therapeutic aspects of the disease.

The purpose of this study was to estimate the prevalence of occupational noise exposure, hearing difficulty and cardiovascular conditions within US industries and occupations, and to examine any associations of these outcomes with occupational noise exposure. National Health Interview Survey data from 2014 were examined. Weighted prevalence and adjusted prevalence ratios of self-reported hearing difficulty, hypertension, elevated cholesterol, and coronary heart disease or stroke were estimated by level of occupational noise exposure, industry, and occupation. Twenty-five percent of current workers had a history of occupational noise exposure (14% exposed in the last year), 12% had hearing difficulty, 24% had hypertension, 28% had elevated cholesterol; 58%, 14%, and 9% of these cases can be attributed to occupational noise exposure, respectively. Hypertension, elevated cholesterol, and hearing difficulty are more prevalent among noise-exposed workers. Reducing workplace noise levels is critical. Workplace-based health and wellness programs should also be considered. Published 2018. This article is a U.S. Government work and is in the public domain in the USA.

[Drugs and occupational accident].
Bratzke, H; Albers, C
1996-02-01
In a case of a fatal occupational accident (construction worker, fall from roof, urine test positive for cocaine and THC, e.g. cannabis) the question arised to what extent those drug-related occupational accidents occur. In the literature only few cases, mainly dealing with cannabis influence, have been reported, however, a higher number is suspected. Cocaine and other stimulating drugs (amphetamine) are more often used to increase physical fitness. By direct or indirect interference with vigilance these compounds may provoke accidents. Due to the lack of a legal basis proving of the influence of drugs at the working place is still very limited, although highly sensitive chemical-toxicological assay procedures are available to detect even the chronic abuse (in hair). In the general conditions of accident insurances a compensation is excluded when alcohol is involved, but drugs are not mentioned. It is indeed difficult to establish a concentration limit for drugs like that existing for alcohol (1.1%). In each case the assay of the drug involved and exact knowledge of its specific effects is in an essential prerequisite to prove the causal relationship.

' Work related musculoskeletal disorders (WRMSDs)' have been mostly reported in the manufacturing industry but recently the occurrence of industrial injuries has been constantly increasing in the service industry. This research is going to analyze the data about workers' compensation for WRMSDs in five different service sectors and identify characteristics of occupations with the highest approved occupations. According to the data released from the Korea Worker's Compensation & Welfare Service, the overview of 12,730 cases of workers' compensation for WRMSDs in five service sectors from 2004 to 2013 is going to be analyzed and the source data is going to be classified by the Korean Standard Classification of Occupations to select the top five occupations that have the highest number of approval. After selecting each five occupations from the service sector that have work related musculoskeletal disorders, the result showed that the occupation with the highest number of approval in the health and social care sector were the early childhood educators, cooks in the school canteens in education services sector, garbage collectors in the sanitation and similar services sector, deliverymen in wholesale and retail, consumer goods repair and building cleaners in general management businesses such as those in building maintenance. The major event observed in the top five occupations was the overexertion and reaction as a cause of WRMSDs. The day when the WRMSDs mostly occurred was on Monday and the most likely time was 10 am. The median days away from work and lost working days are 29-90 days and 0-50 days respectively. The difference in each occupation was observed in year of service, age, and gender. 83.21% of the approved cases of workers' compensation for WRMSDs occurred in the top 25 occupations in all of the five service sectors, which meant that the approval of workers' compensation is concentrated in specific occupations. This research is going to suggest

Prevention of occupational dermatitis.
Sartorelli, P; Kezic, S; Larese Filon, F; John, S M
2011-01-01
Occupational dermatitis is among the most frequent occupational diseases. Dermal exposure risk affects many professional categories such as healthcare workers, hairdressers, bakers, cleaning and kitchen employees. The economical burden of occupational dermatitis (OD) is huge (greater than 5 billion Euro per year in Europe), comprising direct costs (treatment, compensation), as well as indirect costs due to sick leave and lack of productivity. A scientifically based preventive program consisting of skin protection during work, cleaning and skin care after work has generally been recommended to prevent occupational contact dermatitis. However the rate of reported occupational skin diseases seems unchanged in the recent years. In cases of impaired skin condition the secondary prevention (i.e. therapeutic treatment by dermatologists and health-educational intervention seminars) is fundamental. For cases of occupational dermatoses in which these outpatient prevention measures are not successful, interdisciplinary inpatient rehabilitation measures have been developed (tertiary individual prevention). In the past years, various pilot-concepts to improve occupational dermatitis prevention have been successfully put into practice focussing on interdisciplinary (dermatological and educational) skin protection training programmes for high-risk professions. Currently a multi-step intervention approach is implemented which is aiming at offering quick preventive help at all levels of severity of occupational contact dermatitis. Recent data reveals that there are reliable evidence-based options for multidisciplinary prevention and patient management of occupational dermatitis using a combined approach by a network of clinics, practices and statutory social insurance bodies. At this stage, it seemed reasonable to form a European joint initiative for skin prevention. Recently a European network of preventive dermatology (European Initiative for the Prevention of Occupational Skin

Career dissatisfaction among occupational physicians (OP) may affect their performance and the quality of healthcare services provided. Our study aims to assess the job satisfaction of OP serving on the Institutes for Occupational Safety and Health(IOSH) in Tunisia and to identify the determinant factors. We conducted a national cross-sectional validated SAPHORA JOB survey among all the OP serving on 22 IOSH. 58% of OP serving on the IOSH were dissatisfied with their career. Career satisfaction was statistically influenced by the number of healthcare facilities for which they were responsible (p=0.016), the work organisation (p=0.010), the work impact (p=0.011), the salary (p‹10-3) and knowledge on current regulation (p=0.047). The standardisation of pay scale and career ladders for OP serving on the IOSH based on a revision of legislative texts is recommended. Improving organization and working conditions may allow success in the workplace and benefit enhancement.

Studying entrepreneurial occupations in the Terman women.
Schmitt-Rodermund, Eva; Schröder, Elke; Obschonka, Martin
2017-07-16
To achieve a better understanding of entrepreneurship development in women, longitudinal data on 672 individuals collected from 1922 to 1959 were analysed in a secondary investigation of the Terman Longitudinal Study. Women's reports on their occupations during 10 different years were assigned to one of two categories: work for pay (0/1), and work allowing for self-employment (0/1) in the respective year. Structural equation modelling supported earlier results concerning male entrepreneurial activity. Personality and aspects of the parenting context the women had experienced by the average age of 12 predicted early entrepreneurial competencies (inventions, leadership) and occupational interests by age 13, which related to an entrepreneurship-related career goal in 1936, when the participants were about 27 years of age on average. Such a career goal in turn predicted a higher number of occasions of entrepreneurship-prone work. Surprisingly, we also found a relationship to divorce. Women who had experienced the failure of a marriage were in occupations with a potential for entrepreneurship more often. Reasons are discussed against a backdrop of historical timing and current findings to identify general aspects of entrepreneurship development. © 2017 International Union of Psychological Science.

Occupational injuries: is job security a factor?
Saha, Asim; Kulkarni, P K; Chaudhuri, R; Saiyed, H
2005-09-01
Although a large number of contributing factors of occupational injury causation are explored meticulously to explain the phenomenon of higher occupational injury occurrence in some subjects, it has remained a matter of controversy. In this study, an effort is made to explore whether job security has any contribution in explaining higher susceptibility of some workers. This was a retrospective occupational injury record study conducted in an industry of eastern India. Along with the study of injury records of 5 years, an interview was also conducted involving 726 workers (including permanent and temporary workers both) of the factory. Comparison was made between permanent and temporary workers by using the Mann-Whitney U-test and the chi-square test. A theoretical model of Poisson's distribution was used to compare between expected and real occurrence. Although two worker groups were very similar in relation to age, level of education, habits, and nature of work, accident frequency and severity rates were found to be significantly higher in temporary workers. This study concluded that the higher accident risk of the temporary workers might have been due to the less effective experience as well as due to lack of job security inherent in such workers.

Occupations with an increased prevalence of self-reported asthma in Indian adults.
Agrawal, Sutapa; Pearce, Neil; Millett, Christopher; Subramanian, S V; Ebrahim, Shah

Occupational asthma remains relatively under-recognized in India with little or no information regarding preventable causes. We studied occupations with an increased prevalence of self-reported asthma among adult men and women in India. Analysis is based on 64,725 men aged 15-54 years and 52,994 women aged 15-49 years who participated in India's third National Family Health Survey, 2005-2006, and reported their current occupation. Prevalence odds ratios (ORs) for specific occupations and asthma were estimated using multivariate logistic regression, separately for men and women, adjusting for age, education, household wealth index, current tobacco smoking, cooking fuel use, rural/urban residence and access to healthcare. The prevalence of asthma among the working population was 1.9%. The highest odds ratios for asthma were found among men in the plant and machine operators and assemblers major occupation category (OR: 1.67; 95% CI: 1.14-2.45; p = 0.009). Men working in occupation subcategories of machine operators and assemblers (OR: 1.85; 95% CI: 1.24-2.76; p = 0.002) and mining, construction, manufacturing and transport (OR: 1.33; 95% CI: 1.00-1.77; p = 0.051) were at the highest risk of asthma. Reduced odds of asthma prevalence in men was observed among extraction and building trades workers (OR: 0.72; 95% CI: 0.53-0.97; p = 0.029). Among women none of the occupation categories or subcategories was found significant for asthma risk. Men and women employed in high-risk occupations were not at a higher risk of asthma when compared with those in low-risk occupations. This large population-based, nationally representative cross-sectional study has confirmed findings from high income countries showing high prevalence of asthma in men in a number of occupational categories and subcategories; however, with no evidence of increased risks for women in the same occupations.

The purpose of this study was to examine how key occupational therapy terminologies are used by Brazilian occupational therapists. A nominal group approach combined with a Delphi technique involving 31 Brazilian occupational therapists was applied. A sociolinguistic approach was adopted since it broadens our understanding of the social and cultural determinants of terminology consolidation. Brazilian occupational therapists were found to adopt the term activity more often than human action or doing. Even less often were praxis and occupation applied. No consensus was reached regarding which of the terms is most preferred. While Brazilian occupational therapists have been developing their profession from international standards, it is still embedded in local demands and policies. Additionally, the political context must be considered when building an international dialogue between members of a professional body. Such a dialogue could engage professionals from different countries in meaningful exchanges about their practices. These exchanges may lead to the development of solid professional communities that can contribute meaningfully to social change. Copyright 2010 John Wiley & Sons, Ltd.

Many employed people with musculoskeletal conditions rely on healthcare practitioners, including occupational therapists, for work-related advice and support. Good communication between healthcare practitioners and employers is considered vital in facilitating work retention and return to work. The purpose of this study was to explore the experiences of occupational therapists in communicating with patients' employers. Qualitative data were collected from the responses of occupational therapists to ten statements/open questions in a questionnaire survey of UK occupational therapists. Data were copied verbatim into word documents and analysed thematically. A total of 649 comments were made by 143 respondents. Five themes were identified that were associated with communicating with employers: patient-dependent; employer-dependent; therapist-dependent; extrinsic factors; methods of communication. This study has identified that communication between occupational therapists and employers is influenced by a number of factors, including those which are outside the therapists' control. These need to be acknowledged and addressed by therapists, their professional organisation, employers, commissioners, therapy service managers, educators and employees in order to support return-to-work and work retention of people with musculoskeletal conditions.

[The occupational physicians' responsibilities].
Guardavilla, A
2010-01-01
Occupational physicians can commit two kind of crimes: they can violate rules of safety and health at work with no immediate consequences for the employees but anyway creating a potential danger for them, or they can cause, because of their blame, occupational diseases or accidents at work to the employees. In both cases they can be punished. If we want to understand in detail this kind of responsibility, we must read the Supreme Court's judgements (Supreme Court, 19099/2009; 26539/2008; 20220/2006; 17838/2005; 26439/2007; 24290/2005). The numberless innovations introduced in recent years in the body of occupational safety and health laws called for a different reading of the meaning and the content of occupational physicians' functions, requiring them to collaborate, more than in the past, in the assessment of workplace risks. The responsibility of occupational physicians should be seen also in relation to the responsibility of employers and managers (see the link between health surveillance and art. 18 paragraph 1 letter c) of Legislative Decree no. 81/08). In the occupational safety and health context, the employer and his managers must also require (and ensure) occupational physicians to fulfill their obligations and professional duties.

Occupational medicine is a discipline continually evolving in response to technological advances, changes in workplaces and production processes, emergence of new occupational risks and diseases and modifications in regulatory framework for occupational health and safety. Therefore, the recurrent revaluation of professional activity, information demands and education and training needs of occupational physicians is essential in order to identify methodologies and tools that may contribute to improvement of their professional knowledge and competency. In this regard, we conducted the first large-scale national survey of Italian occupational medicine physicians to define their demographic and professional activity and to assess their information demands, training and updating needs. A random sample of occupational physicians, listed in the national register of the Italian Ministry of Health, was selected to complete a voluntary survey. Subjects recruited in this study were asked to complete 3 different sections (personal and professional information, training and updating needs, professional activity and practice characteristics) of a questionnaire for a total of 35 questions. Most of participants were specialized in occupational medicine, worked for a large number of companies and carried out health surveillance on a total number of workers that exceeds 1500. Occupational physicians would like to have a higher training offer towards practical aspects of health surveillance, risks assessment, manual handling of loads, chemical substances and upper limb biomechanical overload. Interestingly, statistically significant differences were observed subdividing the sample into different groups according to the legal requirements to perform the professional activity of occupational physicians in Italy or according to particular aspects of their professional activity. This study has provided interesting findings that may help to guide future discussion on alternative and

Work-related rhinitis, which includes work-exacerbated rhinitis and occupational rhinoconjunctivitis (OR), is two to three times more common than occupational asthma. High molecular weight proteins and low molecular weight chemicals have been implicated as causes of OR. The diagnosis of work-related rhinitis is established based on occupational history and documentation of immunoglobulin E (IgE) mediated sensitization to the causative agent if possible. Management of work-related rhinitis is similar to that of other causes of rhinitis and includes elimination or reduction of exposure to causative agents combined with pharmacotherapy. If allergens are commercially available, allergen immunotherapy can be considered. Copyright © 2011 Elsevier Inc. All rights reserved.

Most of the evidence on agreement between self- and proxy-reported occupational data comes from interview-based studies. The authors aimed to examine agreement between women's reports of their partner's occupation and their partner's own description using questionnaire-based data collected as a part of the prospective, population-based Avon Longitudinal Study of Parents and Children. Information on present occupation was self-reported by women's partners and proxy-reported by women through questionnaires administered at 8 and 21 months after the birth of a child. Job titles were coded to the Standard Occupational Classification (SOC2000) using software developed by the University of Warwick (Computer-Assisted Structured Coding Tool). The accuracy of proxy-report was expressed as percentage agreement and kappa coefficients for four-, three- and two-digit SOC2000 codes obtained in automatic and semiautomatic (manually improved) coding modes. Data from 6016 couples at 8 months and 5232 couples at 21 months postnatally were included in the analyses. The agreement between men's self-reported occupation and women's report of their partner's occupation in fully automatic coding mode at four-, three- and two-digit code level was 65%, 71% and 77% at 8 months and 68%, 73% and 76% at 21 months. The accuracy of agreement was slightly improved by semiautomatic coding of occupations: 73%/73%, 78%/77% and 83%/80% at 8/21 months respectively. While this suggests that women's description of their partners' occupation can be used as a valuable tool in epidemiological research where data from partners are not available, this study revealed no agreement between these young women and their partners at the two-digit level of SOC2000 coding in approximately one in five cases. Proxy reporting of occupation introduces a statistically significant degree of error in classification. The effects of occupational misclassification by proxy reporting in retrospective occupational epidemiological

The aim of this study was to describe the kind of present and future tasks doctors employed in the Occupational Health Service (OHS) in Denmark carried out and to shed light on the reasons why only a moderate number of doctors are employed in the OHS. Additional aims were to map out the number of engaged part-time and full-time doctors in the OHS in Denmark compared with the number of other professionals engaged in the OHS. The study was based on questionnaires sent out to all 109 OHS units in Denmark and to all the doctors employed in the OHS. Ten persons in the OHS were strategically selected for an open interview. There were still only a very few doctors (9%) employed in the OHS in comparison to the other professionals employed in OHS, (nurses, various therapists and technicians) and the doctors were mostly engaged part-time; most of them for less than 10 hours a week. The moderate number of doctors was amongst other things explained by the relatively high cost of the doctors' salaries and the doctors having a reputation for being arrogant and dominating. The doctors were in general very experienced in occupational health matters and solved many problems which required a doctors education. A great deal of the problems they solved were in finding the causality between the workers' symptoms and the working-place conditions. The doctors suggested several future tasks for OHS, e.g. to evaluate its preventive results and to participate in a higher degree when planning working environments.

Occupational Stress and Hypertension among Railway Loco Pilots and Section Controllers.
Jayakumar, Devasigamoney
2017-01-01
A cross-sectional study on occupational stress was conducted on loco pilots in 2008, in view of loco pilots being one of the high strain jobs in Indian Railways. Subsequently, a comparative cross-sectional study on occupational stress was conducted among section controllers in 2011, which is another high strain job of Indian Railways. The studies were conducted to analyze and compare occupational stress and hypertension. A cross-sectional study on occupational stress and hypertension was conducted among 230 loco pilots in 2008, and subsequently, a comparative cross-sectional study was conducted among 82 section controllers in 2011. A closed end 24 item questionnaire on occupational stress was administered. Systolic blood pressure above 140 mmHg and diastolic blood pressure above 90 mmHg were considered as hypertension as per the VII Joint National Committee. Chi-square test and t -test were used for testing significance at P < 0.05. The mean stress score was 8.56 in loco pilots and 7.32 in section controllers. The number of loco pilots with more than 12 stress factors was 49 (21.3%) and the number of section controllers with more than 12 stress factors was 7 (8.5%). The number employees with more than 12 stress factors in different categories of loco pilots were 30 (32%) in the goods category, 12 (12%) in the mail/passenger category, and 7 (19%) in the shunter category, and 3 (11%) in the supervisory category and 4 (7%) in the on-board category of section controllers. The prevalence of hypertension in loco pilots was 36.52% (84) and in the section controllers was 53.66% (44). The prevalence of hypertension in the category with more than 12 stress factors was 30.61% (15) in the loco pilots and 28.57% (2) in the section controllers. The prevalence of hypertension in the both the study groups were higher in the older age, with a family history of hypertension, and with a body mass index of more than 25 kg/m 2 .

Introduction: A cross-sectional study on occupational stress was conducted on loco pilots in 2008, in view of loco pilots being one of the high strain jobs in Indian Railways. Subsequently, a comparative cross-sectional study on occupational stress was conducted among section controllers in 2011, which is another high strain job of Indian Railways. Objective: The studies were conducted to analyze and compare occupational stress and hypertension. Setting and Design: A cross-sectional study on occupational stress and hypertension was conducted among 230 loco pilots in 2008, and subsequently, a comparative cross-sectional study was conducted among 82 section controllers in 2011. Materials and Methods: A closed end 24 item questionnaire on occupational stress was administered. Systolic blood pressure above 140 mmHg and diastolic blood pressure above 90 mmHg were considered as hypertension as per the VII Joint National Committee. Chi-square test and t-test were used for testing significance at P < 0.05. Results: The mean stress score was 8.56 in loco pilots and 7.32 in section controllers. The number of loco pilots with more than 12 stress factors was 49 (21.3%) and the number of section controllers with more than 12 stress factors was 7 (8.5%). The number employees with more than 12 stress factors in different categories of loco pilots were 30 (32%) in the goods category, 12 (12%) in the mail/passenger category, and 7 (19%) in the shunter category, and 3 (11%) in the supervisory category and 4 (7%) in the on-board category of section controllers. The prevalence of hypertension in loco pilots was 36.52% (84) and in the section controllers was 53.66% (44). The prevalence of hypertension in the category with more than 12 stress factors was 30.61% (15) in the loco pilots and 28.57% (2) in the section controllers. The prevalence of hypertension in the both the study groups were higher in the older age, with a family history of hypertension, and with a body mass index of

[TRENDS IN THE RATE OF OCCUPATIONAL PHYSICIANS VERSUS MANPOWER IN ISRAEL - STATUS AND SOLUTIONS].

The specialization in occupational health was recognized in Israel in 1990. The number of specialists grew gradually over the years, yet a systematic analysis of occupational health physicians (OHP)/workers' ratio was never conducted. To determine the trends of OHP/workers' ratio in Israel and the future activities needed in order to achieve the standards of developed countries. The socio-demographic data was obtained by personal communication, from the Israeli Association of Occupational Medicine and Maccabi Health Services. The remaining data was obtained from publications of the Ministry of Health and the National Insurance Institute. By March 2014, 157 OHPs were registered in Israel, 104 active specialists and 25 residents. Among the specialists, 78 worked in the Health Maintenance Organizations (HMO), 18 in the public sector (other than HMOs) and 8 in the private sector. Even though the number of workers rises every year, the number of OHP has remained stable in the last 10 years, around 90-100 physicians. The ratio of occupational health physicians/workers in the HMOs is 1:48,000. The ratio of OHP/workers in Israel is comparable to the ratio in developing countries and 8-10 times less in comparison to the developed countries with a Gross Domestic Product (GDP) similar to Israel. The rate has decreased since 2007. The reason for the stable numbers is the lack of payments by the employers and the fact that the subject has been ignored by the regulatory authorities. The way to improve this situation is by doubling the number of residents every year by providing the required resources to support this new arrangement. The funds have to come from the employers, the Ministry of Economy and the Ministry of Health.

Occupational factors and reproductive outcomes among a cohort of female veterinarians.
Wilkins, J R; Steele, L L
1998-07-01
To estimate absolute and relative risks of preterm delivery (PTD) and small-for-gestational-age (SGA) births among a cohort of female veterinarians in relation to selected occupational factors, including clinical practice type (CPT). Retrospective cohort survey. 2,997 female graduates from US veterinary colleges between 1970 and 1980. Relevant health and occupational data were collected through a self-administered mail questionnaire with telephone follow-up of nonrespondents. Absolute and relative risks of PTD and SGA births were estimated in relation to maternal CPT at the time of conception and exposure to 13 occupational factors. Attempts were made to control confounding by use of multiple logistic regression analyses. Absolute and relative risks of PTD were highest for veterinarians employed in exclusively equine clinical practice. Although several increased, none of the CPT-specific relative risk estimates were significantly different from the null value of 1. Exposure-specific analyses indicated that occupational involvement with solvents among exclusively small animal practitioners was associated with the highest relative risk of PTD. A small number of SGA births limited information that could be obtained from these analyses. Overall absolute risks of PTD and SGA births among cohort members were much lower in comparison with the general female population. Given the large number of women currently practicing and entering the profession of veterinary medicine, clinical tasks associated with potential reproductive hazards should be approached with heightened awareness and increased caution, especially activities that may involve exposure to solvents.

This study assessed the extent and nature of information demands among occupational health physicians and their attitude towards the application of evidence-based medicine in occupational health. A questionnaire survey was carried out among a random sample of 159 physicians practicing occupational medicine in The Netherlands. The questionnaire investigated the type and number of questions encountered in daily practice, the actions taken in response, the physicians' experience in using scientific databases on the Internet, and their attitude towards evidence-based medicine. The occupational health physicians' questions concerned medical, legal, and rehabilitation topics in particular. In pursuing answers to their questions, they generally chose to contact colleagues. Scientific databases were not consulted very often, although, in general, the attitude towards evidence-based medicine was positive. In addition to known barriers for practicing evidence-based medicine, occupational health physicians perceive a lack of scientific evidence in their field. The extensiveness of the field of knowledge in occupational health care was not regarded as an obstacle to their application of evidence-based medicine. Occupational health physicians have a demand for information on a broad range of topics, and, in most cases, their attitude towards evidence-based medicine is fairly positive. Besides education and training in evidence-based medicine, access to the Internet and the presence of a good knowledge infrastructure would help occupational health physicians use evidence-based medicine.

[Backache in insurance companies : Occupational health management].
Thielscher, C; Hahn, E; Klumpp, M; Lindenberg, B; Matusiewicz, D
2016-12-01
The article examines how big German insurance companies handle back pain in terms of occupational health management (OHM). Narrative interviews with experts from 8 out of the 20 biggest enterprises were conducted. Musculoskeletal diseases are the number one or number two reason for sick leave. All enterprises offer OHM; there is a variety of measures, e. g., sport, massage, advice, ergonomics, healthy food and leadership training. The measures are hardly ever evaluated. The literature is controversial whether or which OHM measures are effective. In our sample few measures were evaluated; for more evidence based treatment this should be changed.

Asphalt workers are exposed to polyaromatic hydrocarbons (PAHs) from hot mix asphalt via both inhalation and dermal absorption. The use of crumb rubber modified (CRM) asphalt may result in higher exposure to PAHs and more adverse effects. Our aim is to assess occupational exposure to PAHs from conventional and CRM asphalt paving by measuring PAH metabolites in urine, and to investigate the effects on mitochondrial DNA copy number (mtDNAcn) and telomere length. We recruited 116 workers paving conventional asphalt, 51 workers paving CRM asphalt and 100 controls in Sweden, all males. A repeated-measures analysis included 31 workers paving both types of asphalt. Urine and blood samples were collected pre-working on Monday morning and post-working on Thursday afternoon after 4 days working. PAH metabolites: 1-hydroxypyrene (1-OH-PYR) and 2-hydroxyphenanthrene (2-OH-PH) were measured in urine by LC-MS/MS. Relative mtDNAcn and telomere length were measured by quantitative PCR. Conventional and CRM asphalt workers showed higher 1-OH-PYR and 2-OH-PH than controls (p < 0.001 for all). Relative mtDNAcn were 0.21 units (p < 0.001) higher in conventional asphalt workers and 0.13 units (p = 0.010) higher in CRM asphalt workers compared to controls. Relative telomere length did not differ across occupational groups, but it was positively associated with increment of 2-OH-PH (β = 0.075, p = 0.037) in asphalt workers. The repeated-measures analysis showed no difference in either increment of 1-OH-PYP, or changes in effect biomarkers (mtDNAcn or telomere length) between paving with conventional and CRM asphalt. Increment of 2-OH-PH was smaller after paving with CRM asphalt. Road asphalt paving in open areas resulted in PAHs exposure, as shown by elevation of PAH metabolites in urine. Asphalt workers may experience oxidative stress, evidenced by alternation in mtDNAcn; however the effects could not be fully explained by exposure to PAHs from the asphalt

Occupational injuries are the second leading cause of trauma admission in Qatar. Given the wide diversity of the country's migrant worker populations at risk, this study aimed to analyse and describe the epidemiology of these injuries based on the workers nationality residing in Qatar. A retrospective analysis of trauma registry data on occupational-related injuries was conducted. The analysis included all patients [aged ≥18 years] admitted to the Level I Hamad Trauma Center, from January 1, 2010 to December 31, 2013. Out of 6555 trauma admissions, 2015 (30.7%) patients had occupational injury. The admitted Case Fatality Rate (CFR) was 4.3 per 100 occupational injury related trauma admissions. Overall non-fatal occupational injury rate was 37.34 per 100,000 workers, whereas fatal injury rate was 1.58 per 100,000 workers. Most of the workers experiencing occupational injuries were from Nepal (28%), India (20%) and Bangladesh (9%). Fatal occupational injuries were predominately among Indians (20%), Nepalese (19%), and Filipinos/Bangladeshis (both 8%). Filipinos had the highest admitted CFR at 8.2 deaths per 100 trauma admissions with the next highest being Indians and Indonesians (4.2 per 100 trauma admissions). During the study period, the incidence of severe occupational injuries decreased despite a simultaneous increase in the worker population within Qatar. Almost one in four occupational injuries was a major trauma (ISS≥16). Nepalese and Indian workers represented 29% and 18% of all major trauma cases. Non-fatal occupational injuries appear to follow a pattern distinct from fatal ones. High-risk worker populations as defined by those with high admitted CFRs, experiencing the most severe or fatal injuries, must be the focus of targeted risk factor analysis and occupational safety interventions.

Chest radiography and high-resolution computed tomography are indispensable tools in the detection, classification and characterization of occupational lung diseases that are caused by inhaling mineral particles such as asbestos, silicon-containing rock dust and other tissue-damaging antigens, nanomaterials and toxins. Radiographic evidence of occupational lung disease is interpreted with a patient's clinical signs and symptoms and a detailed occupational history in mind because of high variability in radiographic findings. This Directed Reading reviews the history, epidemiology, functional anatomy, pathobiology and medical diagnostic imaging of occupational lung diseases associated with inhalation of fine particulates in the workplace.

Childhood cancer and occupational radiation exposure in parents.
Hicks, N; Zack, M; Caldwell, G G; Fernbach, D J; Falletta, J M
1984-04-15
To test the hypothesis that a parent's job exposure to radiation affects his or her child's risk of cancer, the authors compared this exposure during the year before the child's birth for parents of children with and without cancer. Parents of children with cancer were no more likely to have worked in occupations, industries, or combined occupations and industries with potential ionizing radiation exposure. Bone cancer and Wilms' tumor occurred more frequently among children of fathers in all industries with moderate potential ionizing radiation exposure. Children with cancer more often had fathers who were aircraft mechanics (odds ratio (OR) = infinity, one-sided 95% lower limit = 1.5; P = 0.04). Although four of these six were military aircraft mechanics, only children whose fathers had military jobs with potential ionizing radiation exposure had an increased cancer risk (OR = 2.73; P = 0.01). Four cancer types occurred more often among children of fathers in specific radiation-related occupations: rhabdomyosarcoma among children whose fathers were petroleum industry foremen; retinoblastoma among children whose fathers were radio and television repairmen; central nervous system cancers and other lymphatic cancers among children of Air Force fathers. Because numbers of case fathers are small and confidence limits are broad, the associations identified by this study need to be confirmed in other studies. Better identification and gradation of occupational exposure to radiation would increase the sensitivity to detect associations.

The integration of occupational therapy into primary care: a multiple case study design
2013-01-01
Background For over two decades occupational therapists have been encouraged to enhance their roles within primary care and focus on health promotion and prevention activities. While there is a clear fit between occupational therapy and primary care, there have been few practice examples, despite a growing body of evidence to support the role. In 2010, the province of Ontario, Canada provided funding to include occupational therapists as members of Family Health Teams, an interprofessional model of primary care. The integration of occupational therapists into this model of primary care is one of the first large scale initiatives of its kind in North America. The objective of the study was to examine how occupational therapy services are being integrated into primary care teams and understand the structures supporting the integration. Methods A multiple case study design was used to provide an in-depth description of the integration of occupational therapy. Four Family Health Teams with occupational therapists as part of the team were identified. Data collection included in-depth interviews, document analyses, and questionnaires. Results Each Family Health Team had a unique organizational structure that contributed to the integration of occupational therapy. Communication, trust and understanding of occupational therapy were key elements in the integration of occupational therapy into Family Health Teams, and were supported by a number of strategies including co-location, electronic medical records and team meetings. An understanding of occupational therapy was critical for integration into the team and physicians were less likely to understand the occupational therapy role than other health providers. Conclusion With an increased emphasis on interprofessional primary care, new professions will be integrated into primary healthcare teams. The study found that explicit strategies and structures are required to facilitate the integration of a new professional group

Occupational radiation procedures and doses in South Korean dentists.
Kim, Yoon-Ji; Cha, Eun Shil; Lee, Won Jin
2016-10-01
Dentistry is among the occupations involving chronic exposure to ionizing radiation. Although several cohort studies on medical radiation workers have been conducted in some countries, only a few epidemiological studies on dentists have been performed to examine occupational radiation exposure worldwide. The aim of this study was to investigate occupational characteristics and radiation exposures in South Korean dentists. A total of 658 dentists were surveyed from April 2012 to May 2013, and survey data were linked with dosimetry data from the National Dose Registry. Multiple linear regression analysis was used to identify the relationship between demographic or occupational factors and individual radiation doses. Of the dentists sampled, 78% were men, 51% were younger than age 40, and 61% began employment after 2000. The most frequent procedures performed by dentists were panoramic radiography, followed by intraoral and portable dental radiography. Male dentists were more frequently involved in radiation procedures, and a higher proportion of male than female dentists wore a lead apron for diagnostic radiology. The average annual effective dose was 0.18 mSv for male and 0.13 mSv for female dentists. Female dentists working in provincial areas had significantly higher average annual and cumulative effective doses than those in metropolitan areas. The cumulative effective doses were significantly greater for older dentists, those who entered the field in the 1990s, and those with longer employment duration. Our findings provided detailed information on work practices, number of procedures performed on a weekly basis, and occupational radiation doses, which enabled in-depth evaluation of occupational radiation exposure and work status among dentists. © 2016 John Wiley & Sons A/S.

Aims: To explore the impact of occupational exposure to whole body vibration (WBV) on low back pain (LBP) in the general population and to estimate the burden of LBP attributable to occupational WBV in comparison with that due to occupational lifting. Methods: A questionnaire including sections on WBV at work, LBP, and potential risk factors was mailed to a community sample of 22 194 men and women of working age. Sources and durations of exposure to occupational WBV were ascertained for the past week and personal vibration doses (eVDV) were estimated. Analysis was confined to subjects reporting exposures in the past week as typical of their work. Associations of LBP with eVDV, driving industrial vehicles, and occupational lifting were explored by logistic regression and attributable numbers were calculated. Results: Significant associations were found between daily lifting of weights greater than 10 kg at work and LBP, troublesome LBP (which made it difficult to put on hosiery), and sciatica (prevalence ratios 1.3 to 1.7); but the risk of these outcomes in both sexes varied little by eVDV and only weak associations were found with riding on industrial vehicles. Assuming causal associations, the numbers of cases of LBP in Britain attributable to occupational WBV were estimated to be 444 000 in men and 95 000 in women. This compared with an estimated 940 000 male cases and 370 000 female cases of LBP from occupational lifting. Conclusions: The burden of LBP in Britain from occupational exposure to WBV is smaller than that attributable to lifting at work. PMID:14504358

Within occupational therapy and occupational science, knowledge regarding occupation-based concepts is in the process of being developed, disseminated and acted upon internationally. It is critical to reflect on the forces shaping the ways in which this knowledge is being constructed. In this paper, the ways in which cultural assumptions and values have influenced the evolving concept of occupational identity are examined through applying Kluckhohn and Strodtbeck's framework of cultural variations in values to two contemporary conceptualisations of occupational identity. The analysis demonstrates the ways in which values most consistent with Western culture are embedded within and dominate these contemporary conceptualisations of occupational identity, emphasising a future orientation, achievement-based doing, individual choice, and mastery of individuals over nature. This paper points to conceptual boundaries within which occupational identity is currently being shaped and points to alternative possibilities in the hope of prompting dialogue and research that looks at this concept in more diverse ways. Heightened sensitivity to the influence of culture on the shaping of occupation-focussed knowledge will serve to strengthen and enrich the growth of the evolving body of knowledge pertaining to occupation, and foster culturally sensitive research and practice.

Background: Many factors contribute to occupational injuries. However, these factors have been compartmentalized and isolated in most studies. Objective: To examine the relationship between work-related injuries and multiple occupational and non-occupational factors among construction workers in the USA. Methods: Data from the 1988–2000 National Longitudinal Survey of Youth, 1979 cohort (N = 12,686) were analyzed. Job exposures and health behaviors were examined and used as independent variables in four multivariate logistic regression models to identify associations with occupational injuries. Results: After controlling for demographic variables, occupational injuries were 18% (95% CI: 1.04–1.34) more likely in construction than in non-construction. Blue-collar occupations, job physical efforts, multiple jobs, and long working hours accounted for the escalated risk in construction. Smoking, obesity/overweight, and cocaine use significantly increased the risk of work-related injury when demographics and occupational factors were held constant. Conclusions: Workplace injuries are better explained by simultaneously examining occupational and non-occupational characteristics. PMID:25816923

The spatial structure of archeological sites can help reconstruct the settlement dynamics of hunter-gatherers by providing information on the number and length of occupations. This study seeks to access this information through a comparison of seven sites. These sites are open-air and were all excavated over large spatial areas, up to 2,000 m(2) , and are therefore ideal for spatial analysis, which was done using two complementary methods, lithic refitting and density zones. Both methods were assessed statistically using confidence intervals. The statistically significant results from each site were then compiled to evaluate trends that occur across the seven sites. These results were used to assess the "spatial consistency" of each assemblage and, through that, the number and duration of occupations. This study demonstrates that spatial analysis can be a powerful tool in research on occupation dynamics and can help disentangle the many occupations that often make up an archeological assemblage. © 2016 Wiley Periodicals, Inc.

Relationships of occupational and non-occupational physical activity to abdominal obesity.
Steeves, J A; Bassett, D R; Thompson, D L; Fitzhugh, E C
2012-01-01
Physically active occupations may protect against the risk of abdominal obesity. This study assessed the interaction between non-occupational physical activity (NOA) (leisure-time, transport and domestic activity) and occupational activity (OA) in relation to abdominal obesity. A total of 3539 adults over the age of 20, with no work limitations, employed in one of the 17 occupations classified as low OA (LOA) or high OA (HOA) were identified in the 1999-2004 National Health and Nutrition Examination Survey. Waist circumference (WC) was used to categorize individuals into either non-obese or abdominally obese (WC>88 cm in women and >102 cm in men) categories. NOA was divided into three categories based upon physical activity guidelines: (1) no NOA; (2) insufficient NOA; and (3) sufficient NOA. Logistic regression was used to examine possible associations between NOA, OA and abdominal obesity. In those who are sedentary outside of work, a high-activity occupation reduces the odds risk ratio of being categorized with abdominal obesity to 0.37 in comparison with those who work in low-activity occupations. For people working in low-activity occupations, there was a clear association with activity outside of work and the odds risk ratio of being categorized with abdominal obesity. In these adults, a reduced odds ratio was found only among those who met the physical activity guidelines through NOA (odds ratio=0.55; 95% confidence interval (CI)=0.40-0.75). HOA is associated with a reduced risk of abdominal obesity. Thus, it is important to include OA in studies seeking to understand the association between physical activity and abdominal adiposity.

Impact of occupational stress on stroke across occupational classes and genders.
Tsutsumi, Akizumi; Kayaba, Kazunori; Ishikawa, Shizukiyo
2011-05-01
The aims of the present study were to analyze the association between incident stroke, occupational class and stress and to examine whether the association is found in both men and women in a prospective study of Japanese male and female workers. A total of 3190 male and 3363 female Japanese community-dwelling workers aged 65 or under with no history of cardiovascular disease were followed. Occupational stress was evaluated using a demand-control questionnaire. The impact on stroke was examined in stratified analyses of occupational classes. We identified 147 incident strokes (91 in men and 56 in women) during the 11-year follow-up period. Men with high strain jobs (combination of high job demand and low job control) were nearly three times more likely to suffer from a stroke than men with low strain jobs (combination of low job demand and high job control). Among male workers in low occupational classes (blue-collar and non-managerial work), job strain was associated with a higher risk of stroke. In contrast, there was no association between job strain and incident stroke among male workers in high occupational classes (white-collar and managerial work). No statistically significant differences were found for stroke incidence among the job characteristic categories in all the female participants. However, significant, over five-fold excess risks were found among white-collar and managerial female workers exposed to high job strain, compared with their counterparts with low strain jobs. Our study of Japanese workers provided supportive evidence for vulnerability to occupational stress among lower occupational class workers in males but not in females. Copyright © 2011 Elsevier Ltd.

Obesity Prevalence by Occupation in Washington State, Behavioral Risk Factor Surveillance System
Lu, Dayu; Fan, Z. Joyce
2014-01-01
Introduction Data that estimate the prevalence of and risk factors for worker obesity by occupation are generally unavailable and could inform the prioritization of workplace wellness programs. The aims of this study were to estimate the prevalence of obesity by occupation, examine the association of occupational physical activity and a range of health behaviors with obesity, and identify occupations in which workers are at high risk of obesity in Washington State. Methods We conducted descriptive and multivariable analyses among 37,626 employed Washington State respondents using the Behavioral Risk Factor Surveillance System in odd numbered years, from 2003 through 2009. We estimated prevalence and prevalence ratios (PRs) by occupational groups adjusting for demographics, occupational physical activity level, smoking, fruit and vegetable consumption, and leisure-time physical activity (LPTA). Results Overall obesity prevalence was 24.6% (95% confidence interval [CI], 24.0–25.1). Workers in protective services were 2.46 (95% CI, 1.72–3.50) times as likely to be obese as workers in health diagnosing occupations. Compared with their counterparts, workers who consumed adequate amounts of fruits and vegetables and had adequate LTPA were significantly less likely to be obese (PR = 0.91; 95% CI, 0.86–0.97 and PR = 0.63; 95% CI, 0.60–0.67, respectively). Workers with physically demanding occupational physical activity had a lower PR of obesity (PR = 0.83; 95% CI, 0.78–0.88) than those with nonphysically demanding occupational physical activity. Conclusion Obesity prevalence and health risk behaviors vary substantially by occupation. Employers, policy makers, and health promotion practitioners can use our results to target and prioritize workplace obesity prevention and health behavior promotion programs. PMID:24406093

[Skin cancer as occupational disease].
Bauer, A
2016-11-01
The incidence of epithelial skin neoplasms, such as squamous cell carcinoma and basal cell carcinoma is significantly increasing worldwide. Leisure time solar UV exposure is causative in the overwhelming majority of cases in the general population; however, occupational exposure is responsible for a certain percentage of cases. Employees with a relevant exposure to polycyclic aromatic hydrocarbons in soot, raw paraffin, coal tar, anthracene, pitch or similar substances, to sunlight in outdoor occupations as well as to arsenic and ionizing radiation have a significantly increased risk to develop occupational skin cancer compared to the general population. In the official occupational disease list in the appendix of the German by-law on occupational diseases, the following occupational diseases concerning skin cancer are listed: BK 5102 "skin cancer and carcinoma in situ caused by soot, raw paraffin, coal tar, anthracene, pitch or similar substances" (e.g. various solid paraffins, asphalt and mazut as well as mineral oils, grease, cylinder and drilling oils), BK 5103 "squamous cell carcinoma or multiple actinic keratosis caused by natural UV radiation", BK 1108 "diseases caused by arsenic and its compounds" and BK 2402 "diseases caused by ionizing radiation". For further occupational exposure to carcinogenic substances and potential occupationally acquired skin tumors, no official lists are currently available. These cancers might be considered under a special opt out paragraph in the German Social Law (§ 9 para 2 SGB VII). Tumors in scars after occupational skin trauma or occupational burns are compensated as consequences of work accidents. The current official list of occupational skin cancers and new developments for expert opinions are described in this article.

Reports by the National Academy of Medicine and leading public health organizations advocate including occupational information as part of an individual's social context. Given recent National Academy of Medicine recommendations on occupation-related data in the electronic health record, there is a critical need for improved representation. The National Institute for Occupational Safety and Health has developed an Occupational Data for Health (ODH) model, currently in draft format. This study aimed to validate the ODH model by mapping occupation-related elements from resources representing recommendations, standards, public health reports and surveys, and research measures, along with preliminary evaluation of associated value sets. All 247 occupation-related items across 20 resources mapped to the ODH model. Recommended value sets had high variability across the evaluated resources. This study demonstrates the ODH model's value, the multifaceted nature of occupation information, and the critical need for occupation value sets to support clinical care, population health, and research. © The Author 2017.

An occupation-industry matrix analysis of mesothelioma cases in Australia 1980-1985.
Yeung, P; Rogers, A
2001-01-01
Australia has one of the highest national incidences of mesothelioma in the world and the rate is still rising. An industry-occupation matrix analysis was conducted for the 858 mesothelioma cases that were reported to the Australian Mesothelioma Surveillance Program between 1980 and 1985. Definite, probable, or possible occupational exposure had occurred in 57 percent (492/858) of the subjects. The primary asbestos production or manufacturing industry constituted the largest number of cases (137/492, 27.8%), followed by shipbuilding, repair and demolition (114/492, 23.2%), the building industry (69/492, 14.1%), and the railway locomotive construction and maintenance industry (47/492, 9.6%). Laborers constituted 14.8 percent (n = 73) of the occupations with a history of exposure to asbestos, followed by carpenters (13.0%, n = 64), boilermakers (10.6%, n = 52), and fitters/turners (8.1%, n = 40). The distribution of occupations in specific industries is presented in this article.

Bed occupancy monitoring: data processing and clinician user interface design.
Pouliot, Melanie; Joshi, Vilas; Goubran, Rafik; Knoefel, Frank
2012-01-01
Unobtrusive and continuous monitoring of patients, especially at their place of residence, is becoming a significant part of the healthcare model. A variety of sensors are being used to monitor different patient conditions. Bed occupancy monitoring provides clinicians a quantitative measure of bed entry/exit patterns and may provide information relating to sleep quality. This paper presents a bed occupancy monitoring system using a bed pressure mat sensor. A clinical trial was performed involving 8 patients to collect bed occupancy data. The trial period for each patient ranged from 5-10 weeks. This data was analyzed using a participatory design methodology incorporating clinician feedback to obtain bed occupancy parameters. The parameters extracted include the number of bed exits per night, the bed exit weekly average (including minimum and maximum), the time of day of a particular exit, and the amount of uninterrupted bed occupancy per night. The design of a clinical user interface plays a significant role in the acceptance of such patient monitoring systems by clinicians. The clinician user interface proposed in this paper was designed to be intuitive, easy to navigate and not cause information overload. An iterative design methodology was used for the interface design. The interface design is extendible to incorporate data from multiple sensors. This allows the interface to be part of a comprehensive remote patient monitoring system.

Background The aim of this study was to examine the feasibility of performing a cohort study on health risks from occupational exposure to radiofrequency electromagnetic fields (RF-EMF) in Germany. Methods A set of criteria was developed to evaluate the feasibility of such a cohort study. The criteria aimed at conditions of exposure and exposure assessment (level, duration, preferably on an individual basis), the possibility to assemble a cohort and the feasibility of ascertaining various disease endpoints. Results Twenty occupational settings with workers potentially exposed to RF-EMF and, in addition, a cohort of amateur radio operators were considered. Based on expert ratings, literature reviews and our set of predefined criteria, three of the cohorts were identified as promising for further evaluation: the personnel (technicians) of medium/short wave broadcasting stations, amateur radio operators, and workers on dielectric heat sealers. After further analyses, the cohort of workers on dielectric heat sealers seems not to be feasible due to the small number of exposed workers available and to the difficulty of assessing exposure (exposure depends heavily on the respective working process and mixture of exposures, e.g. plastic vapours), although exposure was highest in this occupational setting. The advantage of the cohort of amateur radio operators was the large number of persons it includes, while the advantage of the cohort of personnel working at broadcasting stations was the quality of retrospective exposure assessment. However, in the cohort of amateur radio operators the exposure assessment was limited, and the cohort of technicians was hampered by the small number of persons working in this profession. Conclusion The majority of occupational groups exposed to RF-EMF are not practicable for setting up an occupational cohort study due to the small numbers of exposed subjects or due to exposure levels being only marginally higher than those of the general

Disorders Induced by Direct Occupational Exposure to Noise: Systematic Review
Domingo-Pueyo, Andrea; Sanz-Valero, Javier; Wanden-Berghe, Carmina
2016-01-01
Background: To review the available scientific literature about the effects on health by occupational exposure to noise. Materials and Methods: A systematic review of the retrieved scientific literature from the databases MEDLINE (via PubMed), ISI-Web of Knowledge (Institute for Scientific Information), Cochrane Library Plus, SCOPUS, and SciELO (collection of scientific journals) was conducted. The following terms were used as descriptors and were searched in free text: “Noise, Occupational,” “Occupational Exposure,” and “Occupational Disease.” The following limits were considered: “Humans,” “Adult (more than 18 years),” and “Comparative Studies.” Results: A total of 281 references were retrieved, and after applying inclusion/exclusion criteria, 25 articles were selected. Of these selected articles, 19 studies provided information about hearing disturbance, four on cardiovascular disorders, one regarding respiratory alteration, and one on other disorders. Conclusions: It can be interpreted that the exposure to noise causes alterations in humans with different relevant outcomes, and therefore appropriate security measures in the work environment must be employed to minimize such an exposure and thereby to reduce the number of associated disorders.

The Relationship Between Burnout and Occupational Stress in Genetic Counselors.
Johnstone, Brittney; Kaiser, Amy; Injeyan, Marie C; Sappleton, Karen; Chitayat, David; Stephens, Derek; Shuman, Cheryl
2016-08-01
Burnout represents a critical disruption in an individual's relationship with work, resulting in a state of exhaustion in which one's occupational value and capacity to perform are questioned. Burnout can negatively affect an individual's personal life, as well as employers in terms of decreased work quality, patient/client satisfaction, and employee retention. Occupational stress is a known contributor to burnout and occurs as a result of employment requirements and factors intrinsic to the work environment. Empirical research examining genetic counselor-specific burnout is limited; however, existing data suggests that genetic counselors are at increased risk for burnout. To investigate the relationship between occupational stress and burnout in genetic counselors, we administered an online survey to members of three genetic counselor professional organizations. Validated measures included the Maslach Burnout Inventory-General Survey (an instrument measuring burnout on three subscales: exhaustion, cynicism, and professional efficacy) and the Occupational Stress Inventory-Revised (an instrument measuring occupational stress on 14 subscales). Of the 353 respondents, more than 40 % had either considered leaving or left their job role due to burnout. Multiple regression analysis yielded significant predictors for burnout risk. The identified sets of predictors account for approximately 59 % of the variance in exhaustion, 58 % of the variance in cynicism, and 43 % of the variance in professional efficacy. Our data confirm that a significant number of genetic counselors experience burnout and that burnout is correlated with specific aspects of occupational stress. Based on these findings, practice and research recommendations are presented.

Occupational cancer in the European part of the Commonwealth of Independent States.
Bulbulyan, M A; Boffetta, P
1999-01-01
Precise information on the number of workers currently exposed to carcinogens in the Commonwealth of Independent States (CIS) is lacking. However, the large number of workers employed in high-risk industries such as the chemical and metal industries suggests that the number of workers potentially exposed to carcinogens may be large. In the CIS, women account for almost 50% of the industrial work force. Although no precise data are available on the number of cancers caused by occupational exposures, indirect evidence suggests that the magnitude of the problem is comparable to that observed in Western Europe, representing some 20,000 cases per year. The large number of women employed in the past and at present in industries that create potential exposure to carcinogens is a special characteristic of the CIS. In recent years an increasing amount of high-quality research has been conducted on occupational cancer in the CIS; there is, however, room for further improvement. International training programs should be established, and funds from international research and development programs should be devoted to this area. In recent years, following privatization of many large-scale industries, access to employment and exposure data is becoming increasingly difficult. PMID:10350512

Occupational risk factors in inflammatory bowel disease.
Leso, V; Ricciardi, W; Iavicoli, I
2015-08-01
Crohn's disease and ulcerative colitis are the two main forms of inflammatory bowel disease (IBD). Although the aetiology of IBD is not completely understood, an interaction between genetic and environmental factors has been proposed. In this context, however, environmental epidemiology lacks a comprehensive evaluation of the possible role of occupational exposures in IBD development and progression. Therefore, aim of our review was to evaluate how certain occupational risk factors may affect IBD pathogenesis, clinical history and severity of disease manifestations. A critical revision of available literature concerning exposure to groups of potential workplace hazardous agents and IBD, as it appears in Medline and Web of knowledge, was performed. The role of workplace exposures to chemical and biological agents, ionizing or non-ionizing radiations, shift-works, indoor, and sedentary works as well as job strain on IBD has been critically revised. However, the limited number of studies addressing these issues prevented us from extrapolating definite conclusions. Our review pointed out some critical aspects concerning the relationship between occupational factors and IBD, in terms of causative pathways, hazardous exposure, susceptibility and consequences of IBD functional limitations on career choice and fitness for work that need future investigations. Overall, this seems a challenging public health issue, considering the strong IBD impact on patients' quality of life, work productivity and costs to society. Moreover, this review may encourage concerted actions of health care specialists, occupational physicians, employers and IBD workers to plan preventive and protective measures for "healthier patterns of work" for IBD and to develop innovative perspectives for an integrated management of "IBD at work".

Serial peak expiratory flow (PEF) records have been recommended as a first-line investigation in workers suspected as having occupational asthma (OA). To determine which PEF variability index best differentiates workers with OA from non-occupational asthmatics and unaffected irritant-exposed workers. PEF was measured at least four times daily for at least 3 weeks in three groups of subjects: (i) forty healthy grain-exposed farmers and dockers, (ii) forty-two consecutive workers with independently confirmed OA and (iii) forty-eight non-occupational asthmatics. Indices of PEF variability were compared between groups. The difference in mean PEF between rest and work periods best separated the occupational asthmatic workers from the others. The upper 95% confidence limit of this index for grain-exposed workers was 2.8% of predicted PEF (16 l/min) and 3.3% (15 l/min) for non-occupational asthmatics. Sensitivity for diagnosing OA using this index was 70%. An increase in diurnal variation on workdays of >7% had a sensitivity of only 27% for the diagnosis of OA. The difference between maximum PEF on workdays and minimum PEF on rest days had a sensitivity of <10% against non-occupational asthmatic controls. Difference in mean PEF between workdays and rest days is the best simple index for differentiating subjects with OA from those with non-OA or irritant-exposed healthy subjects. Differences >16 l/min are unlikely to be due to significant irritant exposure in healthy workers.

An analysis of occupational homicides involving workers 19 years old and younger.
Janicak, C A
1999-12-01
Studies indicate that persons employed in various retail occupations such as convenience stores and restaurants experience an increased risk for being a victim of an occupational homicide. A large proportion of workers aged 19 and under are employed in these types of occupations. The purpose of this study was to determine if the workers from this age group employed in retail trades have a significantly greater risk for being a victim of a homicide. Data from the Bureau of Labor Statistics' Census of Fatal Occupational Injuries were analyzed in this study. The cases included in this study were victims of an occupational homicide that occurred during the period of 1992 to 1996. Proportionate mortality ratios were used to identify the industries in which workers aged 19 and under were experiencing significantly higher proportion of fatalities. Relative risks were calculated to determine if, based on the number of person-years of exposure, workers aged 19 and under in retail trades were experiencing a significantly greater relative risk for being a victim of an occupational homicide. Results indicate that workers aged 19 and under experience a significantly greater proportion of fatalities due to violence in the retail trade. Workers 19 years and under employed in retail trade occupations do experience a significantly greater proportion of fatalities than their counterparts in other industries. Prevention strategies presented include providing employee training and implementing various security measures.

Occupational contact dermatitis I: incidence and return to work pressures.
Emmett, Edward A
2002-03-01
Since the passage of the United States Occupational Safety and Health Act (OSHA) in 1970, there have been extensive changes in United States workplaces that should have served to enhance the prevention of occupational skin disease (OSD). Analysis of skin diseases reported to OSHA (OSHA recordables) shows that the number of OSDs declined steadily from 1974 to 1983 to about half the previous annual incidence. After 1984, there was a modest resurgence peaking in 1994, with a subsequent decline. A similar but somewhat greater decline in the late 1990s has been observed for occupational respiratory diseases, diseases caused by toxic agents and for poisonings. Likely explanations for the trends in OSD are discussed; the initial decline probably reflected an improvement in workplace conditions, the later resurgence and decline may have been attributable to changes in recording behaviors and in worker's compensation. The decline in recorded OSD since 1996 has been fairly uniform in most major industrial sectors but has been less marked in agriculture, forestry, and fishing so that this sector has replaced manufacturing in recording the highest incidence rate. In 1999, the incidence rate of recorded OSD was 0.49 per 1,000 workers, which appears to grossly under report the true incidence. OSD now constitutes about 10% of all occupational disease cases. Currently, there is increasing emphasis in corporate and occupational medicine on reducing costs and maintaining productivity as well as in preventing occupational injuries and diseases. This is shown by the trend for a greater proportion of workers with occupational conditions to return to modified duty positions rather than to be completely off work. Implications of this phenomena for management of OSD are discussed. Copyright 2002, Elsevier Science (USA). All rights reserved.

This article describes the cost of occupational therapy by provider, insurance status, and geographic region and the number of visits allowed and out-of-pocket costs under proposed therapy caps. This retrospective, population-based study used Medicare Provider Utilization and Payment Data for occupational therapists billing in 2012 and 2013 (Ns = 3,662 and 3,820, respectively). We examined variations in outpatient occupational therapy services with descriptive statistics and the impact of therapy caps on occupational therapy visits and patient out-of-pocket costs. Differences in cost between occupational and physical therapists were minimal. The most frequently billed service was therapeutic exercises. Wisconsin had the most inflated outpatient costs in both years. Under the proposed therapy cap, patients could receive an evaluation plus 12-14 visits. . Wide variation exists in potential patient out-of-pocket costs for occupational therapy services on the basis of insurance coverage and state. Patients without insurance pay a premium.

Occupational seafood allergy: a review
Jeebhay, M; Robins, T; Lehrer, S; Lopata, A
2001-01-01
BACKGROUND—Recent years have seen increased levels of production and consumption of seafood, leading to more frequent reporting of allergic reactions in occupational and domestic settings. This review focuses on occupational allergy in the fishing and seafood processing industry. REVIEW—Workers involved in either manual or automated processing of crabs, prawns, mussels, fish, and fishmeal production are commonly exposed to various constituents of seafood. Aerosolisation of seafood and cooking fluid during processing are potential occupational situations that could result in sensitisation through inhalation. There is great variability of aerosol exposure within and among various jobs with reported allergen concentrations ranging from 0.001 to 5.061(µg/m3). Occupational dermal exposure occurs as a result of unprotected handling of seafood and its byproducts. Occupational allergies have been reported in workers exposed to arthropods (crustaceans), molluscs, pisces (bony fish) and other agents derived from seafood. The prevalence of occupational asthma ranges from 7% to 36%, and for occupational protein contact dermatitis, from 3% to 11%. These health outcomes are mainly due to high molecular weight proteins in seafood causing an IgE mediated response. Cross reactivity between various species within a major seafood grouping also occurs. Limited evidence from dose-response relations indicate that development of symptoms is related to duration or intensity of exposure. The evidence for atopy as a risk factor for occupational sensitisation and asthma is supportive, whereas evidence for cigarette smoking is limited. Disruption of the intact skin barrier seems to be an important added risk factor for occupational protein contact dermatitis. CONCLUSION—The range of allergic disease associated with occupational exposure to crab is well characterised, whereas for other seafood agents the evidence is somewhat limited. There is a need for further epidemiological

OBJECTIVES—To estimate the number of workers in Great Britain with significant occupational exposure to whole body vibration (WBV) and to identify the common sources of exposure and the occupations and industries where such exposures arise. METHODS—A postal questionnaire was posted to a random community sample of 22 194 men and women of working age. Among other things, the questionnaire asked about exposure to WBV in the past week, including occupational and common non-occupational sources. Responses were assessed by occupation and industry, and national prevalence estimates were derived from census information. Estimates were also made of the average estimated daily personal dose of vibration (eVDV). RESULTS—From the 12 907 responses it was estimated that 7.2 million men and 1.8 million women in Great Britain are exposed to WBV at work in a 1 week period if the occupational use of cars, vans, buses, trains, and motor cycles is included within the definition of exposure. The eVDV of >374 000 men and 9000 women was estimated to exceed a proposed British Standard action level of 15 ms-1.75. Occupations in which the estimated exposures most often exceeded 15 ms-1.75 included forklift truck and mechanical truck drivers, farm owners and managers, farm workers, and drivers of road goods vehicles. These occupations also contributed the largest estimated numbers of workers in Great Britain with such levels of exposure. The highest estimated median occupational eVDVs were found in forklift truck drivers, drivers of road goods vehicles, bus and coach drivers, and technical and wholesale sales representatives, among whom a greater contribution to total dose was received from occupational exposures than from non-occupational ones; but in many other occupations the reverse applied. The most common sources of occupational exposure to WBV are cars, vans, forklift trucks, lorries, tractors, buses, and loaders. CONCLUSIONS—Exposure to whole body vibration is

Although, an elevated risk of breast cancer has been suggested for a number of occupations, many earlier studies were limited by selection biases, the incomplete assessment of job histories, and the inability to control for confounding. We examined the relationship between occupational history and breast cancer risk using data from a population-based case-control study of 1,458 cases and 1,556 age-matched controls (90% response rate) conducted in Shanghai, China. Unconditional logistic regression models were used to derive odds ratios (ORs) and 95% confidence intervals (95% CIs) of breast cancer risk associated with occupations and duration of employment adjusting for non-occupational risk factors. The following occupations were found to be associated with an increased risk of breast cancer: laboratory technicians (OR 9.94, 95% CI 1.20-82.37), telephone and telegraph operators (OR 4.63, 95% CI 1.85-11.59), leather and fur processors (OR 3.25, 95% CI 1.11-9.53), and glass-manufacturing workers (OR 2.08, 95% CI 1.14-3.82). A dose-response pattern for years of employment was observed for leather and fur processors (P = 0.02) and glass-manufacturing workers (P = 0.01). Stratified analyses also revealed dose-response relationships between the risk of breast cancer and years of employment as inspector and product analysts among pre-menopausal women (P = 0.02), and as farmers among post-menopausal women (P = 0.04). This study found that several occupations are associated with an increased risk of breast cancer among women. Studies examining various occupational exposures in these high-risk occupations are warranted to identify carcinogens that may play a role in the increased breast cancer risk.

Occupations with an increased prevalence of self-reported asthma in Indian adults
Pearce, Neil; Millett, Christopher; Subramanian, S.V.; Ebrahim, Shah
2014-01-01
Objectives Occupational asthma remains relatively under-recognized in India with little or no information regarding preventable causes. We studied occupations with an increased prevalence of self-reported asthma among adult men and women in India. Methods Analysis is based on 64 725 men aged 15–54 years and 52 994 women aged 15–49 years who participated in India’s third National Family Health Survey, 2005–2006, and reported their current occupation. Prevalence odds ratios (ORs) for specific occupations and asthma were estimated using multivariate logistic regression, separately for men and women, adjusting for age, education, household wealth index, current tobacco smoking, cooking fuel use, rural/urban residence and access to healthcare. Results The prevalence of asthma among the working population was 1.9%. The highest odds ratios for asthma were found among men in the plant and machine operators and assemblers major occupation category (OR: 1.67; 95% CI: 1.14–2.45; p = 0.009). Men working in occupation subcategories of machine operators and assemblers (OR: 1.85; 95% CI: 1.24–2.76; p = 0.002) and mining, construction, manufacturing and transport (OR: 1.33; 95% CI: 1.00–1.77; p = 0.051) were at the highest risk of asthma. Reduced odds of asthma prevalence in men was observed among extraction and building trades workers (OR: 0.72; 95% CI: 0.53–0.97; p = 0.029). Among women none of the occupation categories or subcategories was found significant for asthma risk. Men and women employed in high-risk occupations were not at a higher risk of asthma when compared with those in low-risk occupations. Conclusions This large population-based, nationally representative cross-sectional study has confirmed findings from high income countries showing high prevalence of asthma in men in a number of occupational categories and subcategories; however, with no evidence of increased risks for women in the same occupations.

Access to occupational health services for primary prevention and control of work-related injuries and illnesses by the global workforce is limited (World Health Organization [WHO], 2013). From the WHO survey of 121 (61%) participating countries, only one-third of the responding countries provided occupational health services to more than 30% of their workers (2013). How services are provided in these countries is dependent on legal requirements and regulations, population, workforce characteristics, and culture, as well as an understanding of the impact of workplace hazards and worker health needs. Around the world, many occupational health services are provided by occupational health nurses independently or in collaboration with other disciplines' professionals. These services may be health protection, health promotion, or both, and are designed to reduce health risks, support productivity, improve workers' quality of life, and be cost-effective. Rantanen (2004) stated that basic occupational health services must increase rather than decline, especially as work becomes more complex; workforces become more dynamic and mobile, creating new models of work-places; and jobs become more precarious and temporary. To better understand occupational health services provided by occupational health nurses globally and how decisions are made to provide these services, this study examined the scope of services provided by a sample of participating occupational health nurses from various countries.

Objectives To monitor the impact of health and safety provisions and inform future preventive strategies, we investigated trends in mortality from established occupational hazards in England and Wales. Methods We analysed data from death certificates on underlying cause of death and last full-time occupation for 3,688,916 deaths among men aged 20-74 years in England and Wales during 1979-2010 (excluding 1981 when records were incomplete). Proportional mortality ratios (PMRs), standardised for age and social class, were calculated for occupations at risk of specified hazards. Observed and expected numbers of deaths for each hazard were summed across occupations, and the differences summarised as average annual excesses. Results Excess mortality declined substantially for most hazards. For example, the annual excess of deaths from chronic bronchitis and emphysema fell from 170.7 during 1979-90 to 36.0 in 2001-10, and that for deaths from injury and poisoning from 237.0 to 87.5. In many cases the improvements were associated with falling PMRs (suggesting safer working practices), but they also reflected reductions in the numbers of men employed in more hazardous jobs, and declining mortality from some diseases across the whole population. Notable exceptions to the general improvement were diseases caused by asbestos, especially in some construction trades and sinonasal cancer in woodworkers. Conclusions The highest priority for future prevention of work-related fatalities is the minority of occupational disorders for which excess mortality remains static or is increasing, in particular asbestos-related disease among certain occupations in the construction industry and sinonasal cancer in woodworkers.

Occupant-responsive optimal control of smart facade systems
NASA Astrophysics Data System (ADS)
Park, Cheol-Soo
Windows provide occupants with daylight, direct sunlight, visual contact with the outside and a feeling of openness. Windows enable the use of daylighting and offer occupants a outside view. Glazing may also cause a number of problems: undesired heat gain/loss in winter. An over-lit window can cause glare, which is another major complaint by occupants. Furthermore, cold or hot window surfaces induce asymmetric thermal radiation which can result in thermal discomfort. To reduce the potential problems of window systems, double skin facades and airflow window systems have been introduced in the 1970s. They typically contain interstitial louvers and ventilation openings. The current problem with double skin facades and airflow windows is that their operation requires adequate dynamic control to reach their expected performance. Many studies have recognized that only an optimal control enables these systems to truly act as active energy savers and indoor environment controllers. However, an adequate solution for this dynamic optimization problem has thus far not been developed. The primary objective of this study is to develop occupant responsive optimal control of smart facade systems. The control could be implemented as a smart controller that operates the motorized Venetian blind system and the opening ratio of ventilation openings. The objective of the control is to combine the benefits of large windows with low energy demands for heating and cooling, while keeping visual well-being and thermal comfort at an optimal level. The control uses a simulation model with an embedded optimization routine that allows occupant interaction via the Web. An occupant can access the smart controller from a standard browser and choose a pre-defined mode (energy saving mode, visual comfort mode, thermal comfort mode, default mode, nighttime mode) or set a preferred mode (user-override mode) by moving preference sliders on the screen. The most prominent feature of these systems is the

Mapping similarities in temporal parking occupancy behavior based on city-wide parking meter data
NASA Astrophysics Data System (ADS)
Bock, Fabian; Xia, Karen; Sester, Monika
2018-05-01
The search for a parking space is a severe and stressful problem for drivers in many cities. The provision of maps with parking space occupancy information assists drivers in avoiding the most crowded roads at certain times. Since parking occupancy reveals a repetitive pattern per day and per week, typical parking occupancy patterns can be extracted from historical data. In this paper, we analyze city-wide parking meter data from Hannover, Germany, for a full year. We describe an approach of clustering these parking meters to reduce the complexity of this parking occupancy information and to reveal areas with similar parking behavior. The parking occupancy at every parking meter is derived from a timestamp of ticket payment and the validity period of the parking tickets. The similarity of the parking meters is computed as the mean-squared deviation of the average daily patterns in parking occupancy at the parking meters. Based on this similarity measure, a hierarchical clustering is applied. The number of clusters is determined with the Davies-Bouldin Index and the Silhouette Index. Results show that, after extensive data cleansing, the clustering leads to three clusters representing typical parking occupancy day patterns. Those clusters differ mainly in the hour of the maximum occupancy. In addition, the lo-cations of parking meter clusters, computed only based on temporal similarity, also show clear spatial distinctions from other clusters.

For the assessment of personal exposure, information about the concentration of pollutants when people are in given indoor environments (occupancy time) are of prime importance. However this kind of data frequently is not reported. The aim of this study was to assess differences in particle characteristics between occupancy time and the total monitoring period, with the latter being the most frequently used averaging time in the published data. Seven indoor environments were selected in Sweden and Finland: an apartment, two houses, two schools, a supermarket, and a restaurant. They were assessed for particle number and mass concentrations and number size distributions. The measurements using a Scanning Mobility Particle Sizer and two photometers were conducted for seven consecutive days during winter in each location. Particle concentrations in residences and schools were, as expected, the highest during occupancy time. In the apartment average and median PM2.5 mass concentrations during the occupancy time were 29% and 17% higher, respectively compared to total monitoring period. In both schools, the average and medium values of the PM2.5 mass concentrations were on average higher during teaching hours compared to the total monitoring period by 16% and 32%, respectively. When it comes to particle number concentrations (PNC), in the apartment during occupancy, the average and median values were 33% and 58% higher, respectively than during the total monitoring period. In both houses and schools the average and median PNC were similar for the occupancy and total monitoring periods. General conclusions on the basis of measurements in the limited number of indoor environments cannot be drawn. However the results confirm a strong dependence on type and frequency of indoor activities that generate particles and site specificity. The results also indicate that the exclusion of data series during non-occupancy periods can improve the estimates of particle concentrations and

Potential Health Effects Associated with Dermal Exposure to Occupational Chemicals
Anderson, Stacey E; Meade, B Jean
2014-01-01
There are a large number of workers in the United States, spanning a variety of occupational industries and sectors, who are potentially exposed to chemicals that can be absorbed through the skin. Occupational skin exposures can result in numerous diseases that can adversely affect an individual’s health and capacity to perform at work. In general, there are three types of chemical–skin interactions of concern: direct skin effects, immune-mediated skin effects, and systemic effects. While hundreds of chemicals (metals, epoxy and acrylic resins, rubber additives, and chemical intermediates) present in virtually every industry have been identified to cause direct and immune-mediated effects such as contact dermatitis or urticaria, less is known about the number and types of chemicals contributing to systemic effects. In an attempt to raise awareness, skin notation assignments communicate the potential for dermal absorption; however, there is a need for standardization among agencies to communicate an accurate description of occupational hazards. Studies have suggested that exposure to complex mixtures, excessive hand washing, use of hand sanitizers, high frequency of wet work, and environmental or other factors may enhance penetration and stimulate other biological responses altering the outcomes of dermal chemical exposure. Understanding the hazards of dermal exposure is essential for the proper implementation of protective measures to ensure worker safety and health. PMID:25574139

[Interterritorial inequalities in compensation for occupational diseases in Spain from 1990-2007].
García Gómez, Montserrat; Castañeda López, Rosario
2009-01-01
To determine the reporting pattern and trends for occupational diseases by autonomous communities in Spain between 1990 and 2007. Cases were obtained from the Ministry of Labor and Social Affairs, and the number of workers was obtained from the National Institute of Statistics. A principal components analysis was used to explain the data structure. Adjusted annual incidence rates were computed and relative risk is shown in maps. The number of reported occupational diseases remained constant from 1990 to 2005 in all the autonomous communities, except for minor occupational diseases not leading to sick leave (accounting for 99% of the total), which increased. From 2006-07, reported rates decreased to almost half: 17,061 cases in 2007 versus 30,030 in 2005. Both the increase and the decrease in incidence were observed in all autonomous communities, but with distinct values and slopes. As revealed by the principal components analysis, all the autonomous communities showed the same time pattern, except Asturias. Northern Spain showed the highest rates, which cannot be explained by factors such as age, sex, economic activity or occupation. The social security system is not compensating the complex and chronic diseases that are prevalent today. Despite improvements in disease reporting from 1990-2005, the decrease observed from 2006-07 and, above all, the gap among autonomous communities show that provision is not working with equity, generating inequality and lack of cohesion and posing a challenge for the definition of efficient prevention policies.

Water quality, health, and human occupations.
Blakeney, Anne B; Marshall, Amy
2009-01-01
To introduce evidence of the critical link between water quality and human occupations. A participatory action research design was used to complete a three-phase project. Phase 1 included mapping the watershed of Letcher County, Kentucky. Phase 2 consisted of surveying 122 Letcher County health professionals. Phase 3, the primary focus of this article, consisted of interviews with Letcher County adults regarding their lived experiences with water. The Occupational Therapy Practice Framework: Domain and Process (American Occupational Therapy Association, 2002) was used to structure questions. The Model of Occupational Justice provided the theoretical framework for presentation of the results. The watershed in Letcher County, Kentucky, is polluted as a result of specific coal mining practices and a lack of adequate infrastructure. As a result, citizens experience occupational injustice in the forms of occupational imbalance, occupational deprivation, and occupational alienation.

The burden of mortality with costs in productivity loss from occupational cancer in Italy.
Binazzi, Alessandra; Scarselli, Alberto; Marinaccio, Alessandro
2013-11-01
The costs of productivity loss due to occupational cancer mortality are rarely investigated. An estimate of occupational cancer deaths in Italy in 2006 and an approximation of the resultant costs from medical and non-medical expenditures together with figures of remuneration lost are provided. Occupational cancer deaths, obtained from the application of the attributable fraction (AF) to mortality data (source: Italian National Institute of Statistics), were used to calculate the Potential Years of Life Lost (PYLLs), the Potential Years of Working Life Lost (PYWLLs) and the costs of the loss of productive life. The health care costs for any cancer was applied to the estimated number of occupational cancer cases to obtain the total cost. Around 8,000-8,500 deaths/year from occupational cancer are estimated to occur in Italy, corresponding to 170,000 PYLLs and more than 16,000 PYWLLs, leading to around 360,000,000 euros in indirect economic loss. Health care costs of occupational cancer are estimated at 456,000,000 euros. Occupational cancer is of major concern in terms of mortality and economic productivity loss. Preventive efforts in evaluating ongoing risks and current exposures are strongly recommended to health policy-makers. Copyright © 2013 Wiley Periodicals, Inc.

Previous research showed an increase in Australian suicide rates during the Global Financial Crisis (GFC). There has been no research investigating whether suicide rates by occupational class changed during the GFC. The aim of this study was to investigate whether the GFC-associated increase in suicide rates in employed Australians may have masked changes by occupational class. Negative binomial regression models were used to investigate Rate Ratios (RRs) in suicide by occupational class. Years of the GFC (2007, 2008, 2009) were compared to the baseline years 2001-2006. There were widening disparities between a number of the lower class occupations and the highest class occupations during the years 2007, 2008, and 2009 for males, but less evidence of differences for females. Occupational disparities in suicide rates widened over the GFC period. There is a need for programs to be responsive to economic downturns, and to prioritise the occupational groups most affected.

Gendered occupational segregation remains prevalent across the world. Although research has examined factors contributing to the low number of women in male-typed occupations - namely science, technology, engineering, and math - little longitudinal research has examined the role of childhood experiences in both young women's and men's later gendered occupational attainment. This study addressed this gap in the literature by examining family gender socialization experiences in middle childhood - namely parents' attitudes and work and family life - as contributors to the gender typicality of occupational attainment in young adulthood. Using data collected from mothers, fathers, and children over approximately 15 years, the results revealed that the associations between childhood socialization experiences (∼10 years old) and occupational attainment (∼26 years old) depended on the sex of the child. For sons but not daughters, mothers' more traditional attitudes towards women's roles predicted attaining more gender-typed occupations. In addition, spending more time with fathers in childhood predicted daughters attaining less and sons acquiring more gender-typed occupations in young adulthood. Overall, evidence supports the idea that childhood socialization experiences help to shape individuals' career attainment and thus contribute to gender segregation in the labor market.

Job control and burnout across occupations.
Taris, Toon W; Stoffelsen, Jeroen; Bakker, Arnold B; Schaufeli, Wilmar B; van Dierendonck, Dirk
2005-12-01
Researchers have reported that, for individual workers, low job control is associated with high burnout; however, as yet it is unclear whether this association holds for occupations as well. Whether differences in job control between occupations as assessed by eight expert judges could account for individual-level and occupational-level differences in burnout rates. Data were obtained from 9,503 incumbents of 28 occupations in The Netherlands (M age = 37.9 yr., SD = 8.7; 50% were men). Burnout was measured on the Maslach Burnout Inventory. Occupational-level job control was inversely correlated with burnout, explaining 16% of the variation in occupational-level burnout. Thus, between-occupation differences in job control are somewhat systematically related to burnout.

To examine nonwage losses after occupational injury among health care workers and the factors associated with the magnitude of these losses. Inception cohort of workers filing an occupational injury claim in a Canadian province. Worker self-reports were used to calculate (1) the nonwage economic losses in 2010 Canadian dollars, and (2) the number of quality-adjusted days of life lost on the basis of the EuroQOL Index. Most workers (84%; n = 123) had musculoskeletal injuries (MSIs). Each MSI resulted in nonwage economic losses of Can$3131 (95% confidence interval, Can$3035 to Can$3226), lost wages of Can$5286, and 7.9 quality-adjusted days of life lost within 12 weeks after injury. Losses varied with type of injury, region of the province, and occupation. Non-MSIs were associated with smaller losses. These estimates of nonwage losses should be considered in workers' injury compensation policies and in economic evaluation studies.

Towards an Inclusive Occupational Health and Safety For Informal Workers.
Lund, Francie; Alfers, Laura; Santana, Vilma
2016-08-01
Large numbers of workers worldwide work informally. Yet the discipline and practice of occupational health and safety covers largely only formal workers, in formal work places. A comprehensive approach would have to take into account specific hazards faced by those in different occupations, working in "atypical" work places. Local authorities exert significant influence in the provision of infrastructure that impacts on health and safety, such as water and sanitation. Examples from Brazil and Ghana show that positive interventions are possible so long as informal workers are recognized as contributing to the economy. A more inclusive occupational health and safety is most likely to happen in contexts where informal workers have an organized voice and where there are responsive health and safety personnel who understand that the world of work has changed. Some policy interventions that impact on healthy and safe work will need to involve multiple stakeholders and institutions. © The Author(s) 2016.

Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. To assess the prevalence of occupational allergic contact dermatitis in Indonesian tanneries, identify the causative allergens, and propose a tannery work series of patch test allergens. A cross-sectional study in all workers at two Indonesian tanneries was performed to assess the prevalence of occupational contact dermatitis via a questionnaire-based interview and skin examination. Workers with occupational contact dermatitis were patch tested to identify the causative allergens. Occupational contact dermatitis was suspected in 77 (16%) of the 472 workers. Thirteen (3%) of these 472 workers were confirmed to have occupational allergic contact dermatitis. Potassium dichromate (9.2%), N,N-diphenylguanidine (5.3%), benzidine (3.9%) and sodium metabisulfite (2.6%) were found to be the occupationally relevant sensitizers. The sensitization pattern showed some differences from the data in studies reported from other newly industrial countries. We compiled a 'tannery work series' of allergens for patch testing. A number of these allergens may also be considered for patch testing in patients with (leather) shoe dermatitis. © 2012 John Wiley & Sons A/S.

New developments in occupational dermatology.
Diepgen, Thomas L
2016-09-01
Occupational skin diseases according to BK No. 5101 - "severe or recurrent skin diseases which have forced the person to discontinue all occupational activities that caused or could cause the development, worsening, or recurrence of the disease" - is the most commonly reported notifiable occupational diseases in Germany. Following the optimization of measures of primary, secondary, and tertiary prevention, today most individuals affected are able to continue their profession. With the revision of the German ordinance on occupational diseases (BKV) in January 2015, skin cancer caused by UV irradiation was added to the list of occupational diseases. The new occupational disease (BK) 5103 is defined as "squamous cell carcinoma or multiple actinic keratoses of the skin caused by natural UV irradiation". In this context, "multiple" signifies the occurrence of either more than five individual actinic keratosis lesions over the course of 12 months or the presence of field cancerization of > 4 cm(2) . In the following review, important aspects of this new occupational disease will be highlighted and discussed. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

This study aims, by means of the WorldSID 50th percentile male, to evaluate thoracic loading and injury risk to the near-side occupant due to occupant-to-occupant interaction in combination with loading from an intruding structure. Nine vehicle crash tests were performed with a 50th percentile WorldSID male dummy in the near-side (adjacent to the intruding structure) seat and a THOR or ES2 dummy in the far-side (opposite the intruding structure) seat. The near-side seated WorldSID was equipped with 6 + 6 IR-Traccs (LH and RH) in the thorax/abdomen enabling measurement of bilateral deflection. To differentiate deflection caused by the intrusion, and the deflection caused by the neighboring occupant, time history curves were analyzed. The crash tests were performed with different modern vehicles, equipped with thorax side airbags and inflatable curtains, ranging from a compact car to a large sedan, and in different loading conditions such as car-to-car, barrier, and pole tests. Lateral delta V based on vehicle tunnel acceleration and maximum residual intrusion at occupant position were used as a measurement of crash severity to compare injury measurements. In the 9 vehicle crash tests, thoracic loading, induced by the intruding structure as well as from the far-side occupant, varied due to the size and structural performance of the car as well as the severity of the crash. Peak deflection on the thoracic outboard side occurred during the first 50 ms of the event. Between 70 to 150 ms loading induced by the neighboring occupant occurred and resulted in an inboard-side peak deflection and viscous criterion. In the tests where the target vehicle lateral delta V was below 30 km/h and intrusion less than 200 mm, deflections were low on both the outboard (20-40 mm) and inboard side (10-15 mm). At higher crash severities, delta V 35 km/h and above as well as intrusions larger than 350 mm, the inboard deflections (caused by interaction to the far-side occupant) were of the

Cognitive Orientation to daily Occupational Performance (CO-OP) approach based on cognitive strategy in occupational therapy. To investigate the effects of CO-OP approach on occupational performance in individuals with hemiparetic stroke. This study was designed as a 5-week, randomized, single-blind. Forty-three participants who had a diagnosis of first stroke were enrolled in this study. The participants were randomly assigned to the experimental group (n = 20) or the control group (n = 23). The experimental group conducted CO-OP approach while the control group conducted conventional occupational therapy based on occupational performance components. This study measured Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS). Outcome measurements were performed at baseline and post-intervention. After training, the scores of COPM and PQRS in trained task were significantly higher for the score in the experimental group than the control group. In addition, the non-trained task was significantly higher for the score in the experimental group than the control group in COPM and the PQRS. This study suggests that the CO-OP approach is beneficial effects on the occupational performance to improvement in individuals with hemiparetic stroke, and have positive effects on generalization and transfer of acquired skills.

Diesel engines are widely used in occupational settings. Diesel exhaust has been classified as a lung carcinogen, but data on number of workers exposed to different levels of diesel exhaust are not available in Australia. The aim of this study was to estimate the current prevalence of exposure to diesel engine exhaust in Australian workplaces. A cross-sectional survey of Australian males and females (18-65 years old) in current paid employment was undertaken. Information about the respondents' current job and various demographic factors was collected in a telephone interview using the web-based tool OccIDEAS. Semi-quantitative occupational exposure levels to diesel exhaust were assigned using programmed decision rules and numbers of workers exposed in Australia in 2011 were estimated. We defined substantial exposure as exposed at a medium or high level, for at least 5h per week. Substantial occupational exposure to diesel exhaust was experienced by 13.4% of the respondents in their current job. Exposure prevalence varied across states, ranging from 6.4% in the Australian Capital Territory to 17.0% in Western Australia. Exposures occurred mainly in the agricultural, mining, transport and construction industries, and among mechanics. Men (20.4%) were more often exposed than women (4.7%). Extrapolation to the total working population indicated that 13.8% (95% confidence interval 10.0-20.4) of the 2011 Australian workforce were estimated to be substantially exposed to diesel exhaust, and 1.8% of the workers were estimated to experience high levels of exposures in their current job. About 1.2 million Australian workers were estimated to have been exposed to diesel exhaust in their workplace in 2011. This is the first study to describe the prevalence of occupational diesel exhaust exposure in Australia and will enable estimation of the number of lung cancers attributable to diesel exhaust exposure in the workplace. © The Author 2015.

Experiments on occupancy odor addressed the question of why required ventilation rate per occupant increased progressively with increases in the number of persons in a space. In order to investigate ventilation requirements under approximately ideal conditions, we constructed an aluminum-lined environmental chamber with excellent control over environmental conditions and a ventilation system that provided rapid and uniform mixing of air. Psychophysical experiments on occupancy odor explored 47 different combinations of occupancy density, temperature and humidity, and ventilation rate. The experiments collected judgements both from visitors, who smelled air from the chamber only once every few minutes, and from occupants, whomore » remained in the chamber for an hour at a time. The judgements of visitors revealed that occupancy odor increased only gradually over time and rarely reached very high or objectionable levels. Judgements of occupants also revealed rather minor dissatisfaction. Only during combinations of high temperature and humidity did objectionability become more than a minor issue to either group. Experiments on cigarette smoking explored rates of 4, 8, and 16 cigarettes per hour under various environmental conditions and with ventilation rates as high as 68 cfm (34 L.s/sup -1/) per occupant. As soon as occupants lit cigarettes in the chamber, the odor level increased dramatically. At ventilation rates far greater than necessary to control occupancy odor, the odor from cigarette smoking remained quite intense. In general, the odor proved impossible to control adequately even with a ventilation rate of 68 cfm (34 L.s/sup -1/) per occupant (4 occupants) and even when only one occupant smoked at a time. As in the case of occupancy odor, a combination of high temperature and humidity exacerbated the odor problem.« less

[Under registration of occupational accidents in São Paulo, Brazil, 1997].
Binder, Maria Cecília Pereira; Cordeiro, Ricardo
2003-08-01
To estimate the number of occupational accidents that occurred in a certain municipality during a specific period of time as well as the extent of sub-registration. The study sample was comprised of 4.782 households within the municipality of Botucatu, São Paulo occupied by a total 17,219 inhabitants on the 1st of July, 1997. In each household, an adult inhabitant was interviewed in order to identify the occurrence of occupational accidents in the three months preceding the interview. When such occurrences were identified, the injured workers were interviewed. The Cochran formula was utilized to calculate the confidence interval. Seventy-six individuals confirmed that they had suffered occupational accidents during these three months. In 1997, there were approximately 1,810 occupational accidents in Botucatu, according to our estimates, and the incidence of work related injuries in the population was approximately 4.1% (CI 95% 3.0%-5.3%). Thirty-nine (51.3%, CI 95% 41.1%61.6%) of the above 76 workers were not covered by the Social Security System. Consequently, their injuries were not reported for there was no legally binding obligation to fill out and emit the official registration form - Comunicação de Acidente do Trabalho (CAT) [the work injury report]. Included among the latter are civil servants and informal sector workers, such as self-employed, casual workers and others. Although the remaining 37 workers (48.7%) were covered by the Social Security System and emission of the work injury report was obligatory, 20 of the cases (54.1% CI 95% 39.4%-68.7%) had not been registered. A greater proportion of cases of sub-registration were found among those workers employed in micro, small and medium sized businesses than among those working in large firms. Only 22.4% (CI 13.8%-30.9%) of the occupational accidents reported in this study were registered by the Social Security System. Research findings confirm that analyses based on the number of officially registered

Exposure to bioaerosols has been associated with health deterioration among workers in several occupational environments. This highlights the need to study the microbiological quality of air of workplaces as no such study has been conducted yet in the Philippines. To detect and characterize the culturable mesophilic airborne bacteria in selected occupational environments we used passive sedimentation technique. It was observed that the number of colony-forming units was highest in junk shop, followed by the light railway transit station and last the office. By contrast, the bacterial composition was similar in all sites: Gram-positive cocci > Gram-positive bacilli > Gram-negative bacteria. Staphylococcus aureus and Bacillus spp. were also detected in all sites. These findings suggest that the presence of airborne bacteria may be a potential health hazard in urban occupational environments in the Philippines.

[Market oriented occupational medicine].
Rurik, Imre; Cseh, Károly
2012-09-09
The history and the recent state of occupational medicine in Hungary, and its relation with governmental labor organizations are analyzed. In the past 20 years, large "socialist" factories were replaced by smaller companies employing fewer workers. They have been forced to establish contract with occupational health providers. Many of them offer primary care services, whereas family physicians having a board examination in occupational medicine are allowed to work in this field as well. The market of occupational medicine is less regulated, and ethical rules are not always considered. Undercutting prices is a common practice. The recent system could be improved by some regulations which should be respected. There is no reason to make rough changes establishing a new market for profit oriented insurance companies, and to allow employees and employers to work without specification neglecting international agreements. Occupational medicine should be supervised again by the health authorities instead of economists who have quite different, short-term priorities.

Community occupational therapists have long been involved in the provision of environmental control systems. Diverse electronic technologies with the potential to improve the health and quality of life of selected clients have developed rapidly in recent years. Occupational therapists employ clinical reasoning in order to determine the most appropriate technology to meet the needs of individual clients. This paper describes a number of the drivers that may increase the adoption of information and communication technologies in the occupational therapy profession. It outlines case based reasoning as understood in the domains of expert systems and knowledge management and presents the preliminary results of an ongoing investigation into the potential of a prototype computer aided case based reasoning tool to support the clinical reasoning of community occupational therapists in the process of assisting clients to choose home electronic assistive or smart house technology.

Aims To identify occupations and industries associated with non-Hodgkin lymphoma in a large population-based case-control study in the United States. Methods Cases (n = 1,189) of histologically confirmed malignant NHL ages 20–74 were prospectively identified in four geographic areas covered by the National Cancer Institute SEER Program. Controls (n = 982) were selected from the general population by random digit dialing (< 65 years of age) and from residents listed in Medicare files (65–74 years of age). Odds ratios and 95% confidence intervals for occupations and industries were calculated by unconditional logistic regression analyses, adjusting for age, gender, ethnicity, and study center. Further analyses stratified for gender and histological subtype were also performed. Results Risk of NHL was increased for a few occupations and industries. Several white collar occupations, with no obvious hazardous exposures, had elevated risks, including purchasing agents and buyers, religious workers, physical therapists, and information clerks. Occupations with excesses that may have exposures of interest include launderers and ironers, service occupations, food/beverage preparation supervisors, hand packers and packagers, roofing and siding, leather and leather products, transportation by air, nursing and personal care facilities, and specialty outpatient clinics. Significantly decreased risks of NHL were found for a number of occupations and industries including post secondary teachers and chemical and allied products. Conclusions The results of this study suggest that several occupations and industries may alter the risk of NHL. Our results support previously reported increased risks among farmers, printers, medical professionals, electronic workers, and leather workers. These findings should be evaluated further in larger studies that have the power to focus on specific exposures and histologic subtypes of NHL. PMID:18805886

In order to enhance occupational therapy reasoning in clinical practice, different elements such as client-centred approach, evidence-based care and interdisciplinary work should be taken into account, but is a challenge. To describe the development of the digital Hasselt Occupational Performance Profile (H-OPP © ) that enhances occupational therapy reasoning from ICF perspective. A participative qualitative design was used to create the H-OPP © in an iterative way in which occupational therapy lectures, ICF experts, students and occupational therapists in the field were involved. After linking occupational therapy terminology to the ICF, different stages of the H-OPP were identified and elaborated with main features: generating an occupational performance profile based on inventarization of problems and possibilities, formulating an occupational performance diagnosis and enabling to create an intervention plan. In all stages, both the perspectives of the client and the occupational therapist were taken into account. To increase practical use, the tool was further elaborated and digitalized. The H-OPP © is a digital coach that guides and facilitates professional reasoning in (novice) occupational therapists. It augments involvement of the client system. Furthermore, it enhances interdisciplinary communication and evidence-based care.

We introduce the educational framework of 'threshold concepts' and discuss its utility in understanding the fundamental difficulties learners have in understanding ways of thinking and practising as occupational therapists. We propose that the relationship between occupation and health is a threshold concept for occupational therapy because of students' trouble in achieving lasting conceptual change in relation to their understanding of it. The authors present and discuss key ideas drawn from educational writings on threshold concepts, review the emerging literature on threshold concepts in occupational therapy, and pose a series of questions in order to prompt consideration of the pedagogical issues requiring action by academic and fieldwork educators. Threshold concepts in occupational therapy have been considered in a primarily cross-disciplinary sense, that is, the understandings that occupational therapy learners grapple with are relevant to learners in other disciplines. In contrast, we present a more narrowly defined conception that emphasises the 'bounded-ness' of the concept to the discipline. A threshold concept that captures the essential nature of occupational therapy is likely to be (highly) troublesome in terms of a learner's acquisition of it. Rather than simplifying these learning 'jewels' educators are encouraged to sit with the discomfort that they and the learner may experience as the learner struggles to grasp them. Moreover, they should reshape their curricula to provoke such struggles if transformative learning is to be the outcome. © 2014 Occupational Therapy Australia.

The fundamental goal of this article is to describe, define, and analyze the components of the risk characterization process for occupational exposures. Current methods are described for the probabilistic characterization of exposure, including newer techniques that have increasing applications for assessing data from occupational exposure scenarios. In addition, since the probability of health effects reflects variability in the exposure estimate as well as the dose-response curve—the integrated considerations of variability surrounding both components of the risk characterization provide greater information to the occupational hygienist. Probabilistic tools provide a more informed view of exposure as compared to use of discrete point estimates for these inputs to the risk characterization process. Active use of such tools for exposure and risk assessment will lead to a scientifically supported worker health protection program. Understanding the bases for an occupational risk assessment, focusing on important sources of variability and uncertainty enables characterizing occupational risk in terms of a probability, rather than a binary decision of acceptable risk or unacceptable risk. A critical review of existing methods highlights several conclusions: (1) exposure estimates and the dose-response are impacted by both variability and uncertainty and a well-developed risk characterization reflects and communicates this consideration; (2) occupational risk is probabilistic in nature and most accurately considered as a distribution, not a point estimate; and (3) occupational hygienists have a variety of tools available to incorporate concepts of risk characterization into occupational health and practice.

Occupancy in continuous habitat
Efford, Murray G.; Dawson, Deanna K.
2012-01-01
The probability that a site has at least one individual of a species ('occupancy') has come to be widely used as a state variable for animal population monitoring. The available statistical theory for estimation when detection is imperfect applies particularly to habitat patches or islands, although it is also used for arbitrary plots in continuous habitat. The probability that such a plot is occupied depends on plot size and home-range characteristics (size, shape and dispersion) as well as population density. Plot size is critical to the definition of occupancy as a state variable, but clear advice on plot size is missing from the literature on the design of occupancy studies. We describe models for the effects of varying plot size and home-range size on expected occupancy. Temporal, spatial, and species variation in average home-range size is to be expected, but information on home ranges is difficult to retrieve from species presence/absence data collected in occupancy studies. The effect of variable home-range size is negligible when plots are very large (>100 x area of home range), but large plots pose practical problems. At the other extreme, sampling of 'point' plots with cameras or other passive detectors allows the true 'proportion of area occupied' to be estimated. However, this measure equally reflects home-range size and density, and is of doubtful value for population monitoring or cross-species comparisons. Plot size is ill-defined and variable in occupancy studies that detect animals at unknown distances, the commonest example being unlimited-radius point counts of song birds. We also find that plot size is ill-defined in recent treatments of "multi-scale" occupancy; the respective scales are better interpreted as temporal (instantaneous and asymptotic) rather than spatial. Occupancy is an inadequate metric for population monitoring when it is confounded with home-range size or detection distance.

Trends in compensation for deaths from occupational cancer in Canada: a descriptive study
Del Bianco, Ann
2013-01-01
Background Occupational cancer is the leading cause of work-related deaths, yet it is often unrecognized and under reported, and associated claims for compensation go unfiled. We sought to examine trends in deaths from occupational cancer, high-risk industries and exposures, and commonly compensated categories of occupational cancers. In addition, we compared deaths from occupational lung cancer for which compensation had been given with total deaths from lung cancer. Methods We used data from the Association of Workers’ Compensation Boards of Canada pertaining to the nature and source of the injury or disease and the industry in which it occurred (by jurisdiction) to describe trends in compensated claims for deaths from occupational cancer in Canada for the period 1997–2010. We used data published by the Canadian Cancer Society in Canadian Cancer Statistics to compare compensated occupational lung cancer deaths with total estimated lung cancer deaths for the period between 2006 and 2010. Results Compensated claims for deaths from occupational cancer have increased in recent years and surpassed those for traumatic injuries and disorders in Canada, particularly in Ontario. Between 1997 and 2010, one-half of all compensated deaths from occupational cancer in Canada were from Ontario. High-risk industries for occupational cancer include manufacturing, construction, mining and, more recently, government services. Deaths from lung cancer and mesothelioma comprise most of the compensated claims for deaths from occupational cancer in Ontario and Canada. These diseases are usually the result of asbestos exposure. The burden of other occupational carcinogens is not reflected in claims data. Interpretation Although the number of accepted claims for deaths from occupational cancers has increased in recent years, these claims likely only represent a fraction of the true burden of this problem.

An agent-based stochastic Occupancy Simulator
DOE Office of Scientific and Technical Information (OSTI.GOV)
Chen, Yixing; Hong, Tianzhen; Luo, Xuan
Occupancy has significant impacts on building performance. However, in current building performance simulation programs, occupancy inputs are static and lack diversity, contributing to discrepancies between the simulated and actual building performance. This work presents an Occupancy Simulator that simulates the stochastic behavior of occupant presence and movement in buildings, capturing the spatial and temporal occupancy diversity. Each occupant and each space in the building are explicitly simulated as an agent with their profiles of stochastic behaviors. The occupancy behaviors are represented with three types of models: (1) the status transition events (e.g., first arrival in office) simulated with probability distributionmore » model, (2) the random moving events (e.g., from one office to another) simulated with a homogeneous Markov chain model, and (3) the meeting events simulated with a new stochastic model. A hierarchical data model was developed for the Occupancy Simulator, which reduces the amount of data input by using the concepts of occupant types and space types. Finally, a case study of a small office building is presented to demonstrate the use of the Simulator to generate detailed annual sub-hourly occupant schedules for individual spaces and the whole building. The Simulator is a web application freely available to the public and capable of performing a detailed stochastic simulation of occupant presence and movement in buildings. Future work includes enhancements in the meeting event model, consideration of personal absent days, verification and validation of the simulated occupancy results, and expansion for use with residential buildings.« less

The profession of occupational therapy has a long history of working collaboratively with support personnel. This paper describes the process of a fieldwork education partnership developed between the McMaster University, BHSc (OT) Program and the Mohawk College, Occupational Therapist Assistant and Physical Therapist Assistant Program. Eight student occupational therapists and eight student occupational therapist assistants learned together in a variety of fieldwork settings, either in pairs or in groups. Both groups of students kept weekly journals of the experience and completed a post placement questionnaire. The journals were inductively analysed using a retrospective content analysis. The four emergent themes identified from the data are learning about each other's role, collaborative learning, impact on client care and future practice, and resistance to roles. Recommendations for future collaborations are discussed.

Somatic symptoms among cosmetologists compared to women in other occupations.
Gallicchio, Lisa; Miller, Susan R; Greene, Teresa; Zacur, Howard; Flaws, Jodi A
2011-04-01
Although the literature pertaining to the cosmetology occupation and specific health effects, such as asthma, dermatitis, and reproductive function, has grown substantially, little information is available about whether cosmetologists are at increased risk of other symptoms compared to women working in other occupations. Thus, the purpose of this study was to determine if cosmetologists of reproductive age are at increased risk of self-reported symptoms compared to women of the same age working in other occupations. Data were analyzed from 450 cosmetologists and 511 women in other occupations, aged 21-55 years, in the Baltimore metropolitan region who responded to a mailed survey that ascertained detailed data on symptoms as well as usual work tasks. The data showed that cosmetologists were at increased risk of memory and sleep disturbances, muscle weakness, throat irritation, and hot flashes compared to women of the same age working in other occupations after adjustment for confounders, including cigarette smoking. Among the cosmetologists, handling cleaning supplies; hair bleaching; use of straighteners, texturizers, or permanent chemicals; and several nail care work tasks were associated with one or more of the queried symptoms. Findings from this study suggest that, compared to noncosmetologists, cosmetologists are at increased risk for a number of symptoms reported to be associated with decreased quality of life. These symptoms may also reflect chronic exposure to chemicals that have been shown to be related to more severe long-term health outcomes.

To analyze severe acute occupational poisoning accidents related to irritating gases reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 92 severe acute occupational poisoning accidents related to asphyxiating gases during 15 years, which showed that there were 14.5 accidents occurred each year. Forty types of chemicals were reported to cause poisoning accidents directly. On average, there were 14.5 persons poisoned and 0.8 persons died of poisoning in each event. The number of death of poisoning reached 7 in most of the severe accidents. Chlorine was the main irritating gas resulting in poisoning accidents according to the number of accidents, cases and death. (1) The severe acute occupational poisoning related to irritating gases are more dangerous than others because of it is involved in more cases in each accident. (2) The accidents have concentricity in the certain types of chemicals, industries and jobs, and should be focused on control. (3) It is important to develop the program about early warning and forecast and the first aid.

Occupational health programme for lead workers in battery plants
NASA Astrophysics Data System (ADS)
Lee, Byung-Kook
The realization of problems resulting from the exposure to undue high lead levels of workers in lead-using industries, particularly in storage battery plants, has given rise to a new occupational health service, the so-called type specific (harmful agent specific) group occupational health. In 1988, the Korean Ministry of Labor designated the Institute of Industrial Medicine, Soonchunhyang University, as an authorized organization to take care of lead workers in lead industries. The following occupational health services are provided by the Institute: (i) physical health examination; (ii) biological monitoring with zinc protoporphyrin, urine δ-aminolevulinic acid and blood lead; (iii) respiratory protection with maintenance-free respirators; (iv) measurement of the environmental condition of workplaces; (v) health education. A three-year occupational health programme for lead workers has contributed to improvements in the working conditions of lead industries, particularly in large-scale battery plants, and has decreased the unnecessary high lead burden of workers through on-going medical surveillance with biological monitoring and health education schemes. The strong commitment of both employers and the government to improve the working conditions of lead industries, together with the full cooperation of lead workers, has served to reduce the high lead burdens of lead workers. This decreases the number of lead-poisoning cases and provides more comfortable workplaces, particularly in battery plants.

Few occupational researchers have examined "return to work" among patients with work-related respiratory diseases. In addition, prior studies have emphasized individual patient characteristics rather than a more multi-dimensional approach that includes both clinical and structural factors. A retrospective chart review identified patients with occupational respiratory diseases in the Occupational Health Clinical Center, Syracuse, NY between 1991 and 2009. We assessed predictors of work status using an exploratory, sequential mixed methods research design, multinomial (n = 188) and Cox regressions (n = 130). The findings suggest that patients with an increased number of diagnoses, non-union members, and those who took more than a year before clinical presentation had significantly poorer work status outcomes, after adjusting for age, education level, and relevant diagnoses. Efforts to prevent slow return to work after developing occupational respiratory disease should recognize the importance of timely access to occupational health services, disease severity, union membership, and smoking status. © 2013 Wiley Periodicals, Inc.

In 1997, the Ministry of Health Malaysia introduced a surveillance programme for occupational and work-related diseases including poisonings for cases seen in government health facilities. Between June 1997 and November 1998, there were 36 cases of respiratory disease and 95 cases of poisoning by chemicals and pesticides notified while skin diseases were 108 cases. Respiratory diseases reported were predominantly occupational asthma (25%), pneumoconiosis (17%) and infections (39%). The commonest reported skin disease was contact dermatitis (87%). The commonest causes of occupational poisonings were paraquat (19%), organo-phosphates (16%), agro-chemicals excluding pesticides (15%) and gases (10%). The number of cases reported is still relatively few compared to data from other countries, suggesting that there is still considerable under reporting.

Occupational diseases in Murmansk Oblast: 1980-2010.
Dudarev, Alexey A; Talykova, Liudmila V; Odland, Jon Øyvind
2013-01-01
Official statistics tend to underestimate the incidence of occupational disease (OD) nationally and regionally in Russia. The general aim was to obtain an accurate estimate of ODs in Murmansk Oblast in 1980-2010 and to determine the rate of specific types of ODs among cohorts of workers who had been exposed to the hazardous factors causing the disease. Data were retrieved from the Murmansk Oblast ODs database for the oblast and 2 enterprises--Apatite JSC and Kolskaya MSC--which contributed to more than half of the ODs in the oblast in 1980-2010. The total number of ODs and 5 specific categories (musculoskeletal, respiratory, nervous diseases, hearing loss and vibration disease) were analysed. THE TOTAL RATE OF ODS AMONG WORKERS OF MAIN SHOPS IN BOTH ENTERPRISES WHO WERE ACTUALLY EXPOSED TO HARMFUL FACTORS WERE EXTREMELY HIGH: the rate for Apatite JSC was 25 times higher than in Russia and 15 times higher than in Murmansk Oblast, while the rate for Kolskaya MSC was about 30 and 20 times greater than in Russia and in Murmansk Oblast, respectively; in the 2000s the difference reached 100-150 times. The rise in reported ODs in both enterprises corresponded to the time when intensive medical examinations were conducted by the Kola Research Laboratory for Occupational Health (KRLOH) in Kirovsk. A similar pattern was also observed for the sub-categories of musculoskeletal, respiratory, nervous diseases, hearing loss and vibration disease. It is likely that the true burden of OD is even higher due to misdiagnosis, reluctance of workers concerned about job security to present for care and the lack of reliable information on working conditions needed to establish a causal link between disease and occupational exposure. As with many other regions across Russia, ODs in Murmansk Oblast are grossly underestimated. Serious problems exist in the Russian occupational health care system and the collection of occupational health statistics that require urgent, fundamental reform.

Occupational lung diseases in Australia.
Hoy, Ryan F; Brims, Fraser
2017-11-20
Occupational exposures are an important determinant of respiratory health. International estimates note that about 15% of adult-onset asthma, 15% of chronic obstructive pulmonary disease and 10-30% of lung cancer may be attributable to hazardous occupational exposures. One-quarter of working asthmatics either have had their asthma caused by work or adversely affected by workplace conditions. Recently, cases of historical occupational lung diseases have been noted to occur with new exposures, such as cases of silicosis in workers fabricating kitchen benchtops from artificial stone products. Identification of an occupational cause of a lung disease can be difficult and requires maintaining a high index of suspicion. When an occupational lung disease is identified, this may facilitate a cure and help to protect coworkers. Currently, very little information is collected regarding actual cases of occupational lung diseases in Australia. Most assumptions about many occupational lung diseases are based on extrapolation from overseas data. This lack of information is a major impediment to development of targeted interventions and timely identification of new hazardous exposures. All employers, governments and health care providers in Australia have a responsibility to ensure that the highest possible standards are in place to protect workers' respiratory health.

Occupation- and industry-based risks for stroke and ischemic heart disease may vary among Japanese working-aged men. We examined the differences in mortality rates between stroke and ischemic heart disease by occupation and industry among employed Japanese men aged 25-59 years. In 2010, we obtained occupation- and industry-specific vital statistics data from the Japanese Ministry of Health, Labour, and Welfare dataset. We analyzed data for Japanese men who were aged 25-59 years in 2010, grouped in 5-year age intervals. We estimated the mortality rates of stroke and ischemic heart disease in each age group for occupation and industry categories as defined in the national census. We did not have detailed individual-level variables. We used the number of employees in 2010 as the denominator and the number of events as the numerator, assuming a Poisson distribution. We conducted separate regression models to estimate the incident relative risk for stroke and ischemic heart disease for each category compared with the reference categories "sales" (occupation) and "wholesale and retail" (industry). When compared with the reference groups, we found that occupations and industries with a relatively higher risk of stroke and ischemic heart disease were: service, administrative and managerial, agriculture and fisheries, construction and mining, electricity and gas, transport, and professional and engineering. This suggests there are occupation- and industry-based mortality risk differences of stroke and ischemic heart disease for Japanese working-aged men. These differences in risk might be explained to factors associated with specific occupations or industries, such as lifestyles or work styles, which should be explored in further research. The mortality risk differences of stroke and ischemic heart disease shown in the present study may reflect an excessive risk of Karoshi (death from overwork).

Promoting Occupational Health Nursing Training
Ward, Julie A.; Beaton, Randal D.; Bruck, Annie M.; de Castro, A. B.
2012-01-01
In 2009, occupational health nursing faculty and professionals at the University of Washington developed an innovative continuing nursing education offering, the OHN Institute. The OHN Institute was designed to meet the following objectives: (1) extend basic occupational health nursing training to non-occupational health nurses in Federal Region X, (2) target new occupational health nurses or those who possessed little or no advanced education in occupational health nursing, and (3) offer a hybrid continuing nursing education program consisting of on-site and distance learning modalities. Evaluation findings suggested that the various continuing nursing education modalities and formats (e.g., asynchronous vs. synchronous, online modules vs. live modules) were essentially comparable in terms of effectiveness. Perhaps most importantly, the OHN Institute evaluation demonstrated that quality continuing nursing education outcomes for occupational health nurses depended largely on knowledgeable and engaging faculty and a compelling vision of desired outcomes, including the application of learned content to professional practice.

Multi-User Low Intrusive Occupancy Detection
Widyawan, Widyawan; Lazovik, Alexander
2018-01-01
Smart spaces are those that are aware of their state and can act accordingly. Among the central elements of such a state is the presence of humans and their number. For a smart office building, such information can be used for saving energy and safety purposes. While acquiring presence information is crucial, using sensing techniques that are highly intrusive, such as cameras, is often not acceptable for the building occupants. In this paper, we illustrate a proposal for occupancy detection which is low intrusive; it is based on equipment typically available in modern offices such as room-level power-metering and an app running on workers’ mobile phones. For power metering, we collect the aggregated power consumption and disaggregate the load of each device. For the mobile phone, we use the Received Signal Strength (RSS) of BLE (Bluetooth Low Energy) nodes deployed around workspaces to localize the phone in a room. We test the system in our offices. The experiments show that sensor fusion of the two sensing modalities gives 87–90% accuracy, demonstrating the effectiveness of the proposed approach. PMID:29509693

Occupational noise exposure and hearing levels
DOE Office of Scientific and Technical Information (OSTI.GOV)
Ambasankaran, M.; Brahmachari, D.; Chadda, V.K.
1981-07-01
A study was made at the Bhabha Atomic Research Center to measure the hearing levels of persons working in a noise environment. Two different workplaces, central air-conditioning plant and glass blowing shops, where a number of persons were exposed to noise levels exceeding 85 dB(A) were chosen. The occupational exposure to noise was determined using a sound level meter, an octave band filter and a personal noise dose meter. The hearing levels of persons exposed to these high levels of noise and a control group not exposed to occupational noise were measured by means of a pure-tone audiometer in amore » specially-built booth. These persons, aged between 20 to 60 years, were divided into four age groups for the study. The low ambient noise levels in the booth were measured using correlation technique since such low signals cannot be detected by an ordinary sound level meter. The audiometric findings and the results of the noise level survey are discussed in this paper.« less

Shoe manufacturing workers are exposed daily to an extensive range of potential physical and chemical occupational hazards. Shoe manufacturing in Indonesia is one of the industrial sectors that has shown sustained growth amongst the newly industrialized countries (NICs). In this study, we investigated the possible potential exposure of the workers to physical and occupational hazards and determined the prevalence of occupational skin diseases at a shoe manufacturing factory in Indonesia. A cross-sectional study on the observation of the working process and an inventory and risk assessment of exposure to the chemicals used. Classification of chemicals as potential sensitizers/irritants and qualitative assessments of these chemicals were done. Workers were examined and interviewed using the Nordic Occupational Skin Questionnaire-2002/LONG. The risk of Occupational skin diseases (OSD) at the shoe factory was mainly related to the exposure of the workers' skin to potential physical and chemical hazards in hot and humid environmental conditions. From a total of 514 workers, 8.5 % reported current OSD and 4.8 % reported a history of OSD. Occupational skin diseases were diagnosed in 29 % of the workers by dermatologists and 7.6 % had an occupational contact dermatitis (OCD). Of the 39 workers with contact dermatitis, 33 consented to being patch tested, 14 (3 %) workers showed a positive results and considered as having an occupational allergic contact dermatitis (OACD) and 25 (4.9 %) had an occupational irritant contact dermatitis (OICD). We observed a repeated and prolonged exposure of the workers to numerous physical and chemical skin hazards at this factory.

Occupant perception of indoor air and comfort in four hospitality environments.
Moschandreas, D J; Chu, P
2002-01-01
This article reports on a survey of customer and staff perceptions of indoor air quality at two restaurants, a billiard hall, and a casino. The survey was conducted at each environment for 8 days: 2 weekend days on 2 consecutive weekends and 4 weekdays. Before and during the survey, each hospitality environment satisfied ventilation requirements set in ASHRAE Standard 62-1999, Ventilation for Acceptable Indoor Air. An objective of this study was to test the hypothesis: If a hospitality environment satisfies ASHRAE ventilation requirements, then the indoor air is acceptable, that is, fewer than 20% of the exposed occupants perceive the environment as unacceptable. A second objective was to develop a multiple regression model that predicts the dependent variable, the environment is acceptable, as a function of a number of independent perception variables. Occupant perception of environmental, comfort, and physical variables was measured using a questionnaire. This instrument was designed to be efficient and unobtrusive; subjects could complete it within 3 min. Significant differences of occupant environment perception were identified among customers and staff. The dependent variable, the environment is acceptable, is affected by temperature, occupant density, and occupant smoking status, odor perception, health conditions, sensitivity to chemicals, and enjoyment of activities. Depending on the hospitality environment, variation of independent variables explains as much as 77% of the variation of the dependent variable.

The Role of the Occupational Therapist in Disaster Areas: Systematic Review
Parente, M.; De Santis, R.; Esposito, G.; Santilli, V.
2017-01-01
Background Disasters are increasingly more frequent events on our planet. During disaster the role of the occupational therapist will require a more specific operative framework within nongovernmental organizations and community health services. Design Systematic review. Objective The aim of this study is to evaluate the evidence that highlight occupational therapist's role in disaster area through a systematic review. Materials and Methods Research on MEDLINE was performed. All articles from 2005 to 2015 concerning rehabilitation and occupational therapy in disaster areas were included. Results Ten studies were selected to be included in this review. Four interesting points emerged: the importance of having rehabilitation intervention in postdisaster situations, the necessity to include a rehabilitation team in the early phase of disaster response, the need to provide a method to address the difficult evacuation, and finding the safest method of transport of people with preexisting disabilities and new injuries. Conclusions The amount of evidence with respect to specific intervention of the occupational therapist's role in a disaster situation is limited. However some evidence suggests that it could be a good means for reducing the number of medical complications and deaths of persons with preexisting disabilities. The evidences found highlight the necessity to create a multidisciplinary team addressing needs in disasters situation, in which the occupational therapist could certainly contribute. PMID:29097975

Recovering substance-impaired pharmacists' views regarding occupational risks for addiction.
Merlo, Lisa J; Cummings, Simone M; Cottler, Linda B
2012-01-01
To better understand the occupational risks for substance use disorders among pharmacists and possibilities for improved prevention. Descriptive, nonexperimental, cross-sectional study. A southeastern state from December 2008 to April 2009. 32 participants (72.7% men) from the impaired professionals monitoring groups in the geographic regions within the state that had the greatest number of physicians, pharmacists, and allied health professionals currently under monitoring contracts for substance use disorders. Guided group discussions regarding substance use among health care providers. Persistent occupational risks for development of a substance use disorder among pharmacists. Several occupational hazards unique to the pharmacy profession might contribute to the problem of substance use disorders among some members of this population, including increased access to potent drugs of abuse, a stressful/unpleasant working environment, a culture that unofficially condones medication diversion, lack of education related to addiction, and lack of support for individuals seeking treatment. These results have important implications for the education of student pharmacists, the continuing education of licensed pharmacists, and the management of pharmacies in which these individuals work. Given the potential occupational risks for substance abuse associated with the pharmacy profession, additional training, monitoring, changes to the work environment, and increased confidential access to treatment may be needed to safeguard pharmacy professionals and the communities they serve.

Toward risk reduction: predicting the future burden of occupational cancer.
Hutchings, Sally; Rushton, Lesley
2011-05-01
Interventions to reduce cancers related to certain occupations should be evidence-based. The authors have developed a method for forecasting the future burden of occupational cancer to inform strategies for risk reduction. They project risk exposure periods, accounting for cancer latencies of up to 50 years, forward in time to estimate attributable fractions for a series of forecast target years given past and projected exposure trends and under targeted reduction scenarios. Adjustment factors for changes in exposed numbers and levels are applied in estimation intervals within the risk-exposure periods. The authors illustrate the methods by using a range of scenarios for reducing lung cancer due to occupational exposure to respirable crystalline silica. Attributable fractions for lung cancer due to respirable crystalline silica could be potentially reduced from 2.07% in 2010 to nearly 0% by 2060, depending on the timing and success of interventions. Focusing on achieving compliance with current exposure standards in small industries can be more effective than setting standards at a lower level. The method can be used to highlight high-risk carcinogens, industries, and occupations. It is adaptable for other countries and other exposure situations in the general environment and can be extended to include socioeconomic impact assessment.

Background: Asbestos-related diseases (ARD) are occupational hazards with high mortality rates. To identify asbestos exposure by previous occupation is the main issue for ARD compensation for workers. This study aimed to identify risk groups by applying standard classifications of industries and occupations to a national database of compensated ARD victims in Japan. Methods: We identified occupations that carry a risk of asbestos exposure according to the International Standard Industrial Classification of All Economic Activities (ISIC). ARD compensation data from Japan between 2006 and 2013 were retrieved. Each compensated worker was classified by job section and group according to the ISIC code. Risk ratios for compensation were calculated according to the percentage of workers compensated because of ARD in each ISIC category. Results: In total, there were 6,916 workers with ARD who received compensation in Japan between 2008 and 2013. ISIC classification section F (construction) had the highest compensated risk ratio of 6.3. Section C (manufacturing) and section F (construction) had the largest number of compensated workers (2,868 and 3,463, respectively). In the manufacturing section C, 9 out of 13 divisions had a risk ratio of more than 1. For ISIC divisions in the construction section, construction of buildings (division 41) had the highest number of workers registering claims (2,504). Conclusion: ISIC classification of occupations that are at risk of developing ARD can be used to identify the actual risk of workers’ compensation at the national level.

‘Without Occupation You Don't Exist’: Occupational Engagement and Mental Illness
Blank, Alison Anne; Harries, Priscilla; Reynolds, Frances
2015-01-01
This phenomenological study explores the meanings of work for people living with severe and enduring mental health conditions. The participants were three women and seven men who were attending a mental health day centre. Data were collected through up to three depth interviews with each participant over 18 months. The interviews were digitally recorded, transcribed verbatim, and analysed according to phenomenological principles. Two overarching themes were identified. Building and maintaining an occupational identity expressed the ways in which participants used occupations as the building blocks of an evolving identity. Most of the participants wanted to work, and participation in occupations was seen as essential to recovery from mental ill-health. Work and other ways of belonging encapsulated the need to feel connected to others. Many of the participants envisaged working as a way of achieving this. The longitudinal nature of the study facilitated engagement with the developing narratives and exploration of the changes and consistencies in the participants' meaning making about their occupations. Implications for understanding individuals' occupational participation which enhances a sense of self and promotes feelings of belonging are identified. PMID:25866474

This study explores motivations, job satisfaction, and overall perceived occupational mobility for African immigrants working in low-wage direct health care occupations. The study uses qualitative semi-structured interviews with a sample of thirty African immigrant workers in the greater Pittsburgh metropolitan area. Results show that four major themes captured the motivations of interviewees for doing direct care work: passion for care work, quick money, easily obtained employment, and direct care work as a pathway to other health occupations. The majority of the interviewees were satisfied with their jobs, yet almost all of them saw their occupations as temporary or transitional employment. Most of the interviewees also saw their jobs as lacking occupational mobility. In light of the increased national demand for direct care workers, the growing numbers of immigrants in the direct care labor force, and the high turnover and low retention rates of direct care workers overall, the study suggests that more must be done to make direct care work attractive and rewarding for African immigrant workers.

The Intentional Relationship Model (IRM) is a new model of the therapeutic relationship in occupational therapy practice. Two previous studies have focused on therapist communication style, or 'mode' use, but to date no group comparisons have been reported. To explore differences between occupational therapists and occupational therapy students with regard to their therapeutic mode use. The study had a cross-sectional design, and convenience samples consisting of occupational therapists (n = 109) and of second-year occupational therapy students (n = 96) were recruited. The Self-Assessment of Modes Questionnaire was the main data collection tool. Group differences were analysed with independent t-tests. The occupational therapists responded more within the collaborative and empathizing modes than the students did. The students responded more within the advocating and instructing modes than the occupational therapists did. There may be systematic differences between occupational therapists and students concerning their therapeutic mode use. Some modes, such as the collaborating and empathizing modes, may be viewed as requiring more experience, whereas other modes, such as the advocating mode may be related to more recent rehabilitation ideologies. These factors may contribute to explaining several of the group differences observed.

2008-01-01
The aim of the work--the investigation of peculiarities of psychosomatic relations in patients with different stages of hypertensive disease (HD) in conditions of direct occupation activity. The 225 workers from a number of large pharmaceutical industries, who was engaged in performance of the basic occupation activities in conditions of conveyor manufacture at the alternating working regimen, that seemed to be an origin of stresses. On grounds of blood pressure level the patients were selected into 3 groups. The 65 cases with border arterial hypertension (BAH) were included into the 1st group, 69 patients with stage 1 HB were included into the 2nd group and 61 patient--into the third group. The control group consisted of 30 health volunteers. The results of the study testify that occupational stress results in development of neurosis, stable sympathicotonia with formation of hyperkinetic and in consequent advance--hypokinetic type of circulation, gradual aggravation of changes from heart side, decrease of productiveness of mentality. One of causes of persistence of neurosis is a deficiency of a pragmatic information in conditions of complicate and strenuous process of occupational activity.

Occupational Health Hazards in ICU Nursing Staff
Shimizu, Helena Eri; Couto, Djalma Ticiani; Merchán-Hamann, Edgar; Branco, Anadergh Barbosa
2010-01-01
This study analyzed occupational health hazards for Intensive Care Unit (ICU) nurses and nursing technicians, comparing differences in the number and types of hazards which occur at the beginning and end of their careers. A descriptive cross-sectional study was carried out with 26 nurses and 96 nursing technicians from a public hospital in the Federal District, Brazil. A Likert-type work-related symptom scale (WRSS) was used to evaluate the presence of physical, psychological, and social risks. Data were analyzed with the use of the SPSS, version 12.0, and the Kruskal-Wallis test for statistical significance and differences in occupational health hazards at the beginning and at the end of the workers' careers. As a workplace, ICUs can cause work health hazards, mostly physical, to nurses and nursing technicians due to the frequent use of physical energy and strength to provide care, while psychological and social hazards occur to a lesser degree.
