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

Motor vehicle crashes result in some 1.2 million deaths and many more injuries worldwide each year and is one of the biggest public health problems facing societies today. This article reviews the history of, and future potential for, one important countermeasure-designing vehicles that reduce occupant deaths and injuries. For many years, people had urged automakers to add design features to reduce crash injuries, but it was not until the mid-1960s that the idea of pursuing vehicle countermeasures gained any significant momentum. In 1966, the U.S. Congress passed the National Traffic and Motor Vehicle Safety Act, requiring the government to issue a comprehensive set of vehicle safety standards. This was the first broad set of requirements issued anywhere in the world, and within a few years similar standards were adopted in Europe and Australia. Early vehicle safety standards specified a variety of safety designs resulting in cars being equipped with lap/shoulder belts, energy-absorbing steering columns, crash-resistant door locks, high-penetration-resistant windshields, etc. Later, the standards moved away from specifying particular design approaches and instead used crash tests and instrumented dummies to set limits on the potential for serious occupant injuries by crash mode. These newer standards paved the way for an approach that used the marketplace, in addition to government regulation, to improve vehicle safety designs-using crash tests and instrumented dummies to provide consumers with comparative safety ratings for new vehicles. The approach began in the late 1970s, when NHTSA started publishing injury measures from belted dummies in new passenger vehicles subjected to frontal barrier crash tests at speeds somewhat higher than specified in the corresponding regulation. This program became the world's first New Car Assessment Program (NCAP) and rated frontal crashworthiness by awarding stars (five stars being the best and one the worst) derived from head

The workplace is a key setting where gender issues and organizational structures may influence occupational health and safety practices. The enactment of dominant norms of masculinity in high risk occupations can be particularly problematic, as it exposes men to significant risks for injuries and fatalities. To encourage multi-disciplinary collaborations and advance knowledge in the intersecting areas of gender studies, men's health, work and workplace health and safety, a national network of thirteen researchers and health and safety stakeholders completed a critical literature review examining the intersection between masculinities and men's workplace health and safety in order to: (i) account for research previously undertaken in this area; (ii) identify themes that may inform our understanding of masculinity and workplace health and safety and; (iii) identify research and practice gaps in relation to men's workplace health and safety. In this paper we present key themes from this review. Recommendations are made regarding: (i) how to define gender; (ii) how to attend to and identify how masculinities may influence workers' identities, perceptions of occupational risks and how institutionalized practices can reinforce norms of masculinity; (iii) the importance of considering how masculinities may intersect with other variables (e.g. historical context, age, class, race, geographical location) and; (iv) the added significance of present-day labour market forces on men's occupational health and safety.

Surgery is a demanding and stressful field in Korea. Occupational stress can adversely affect the quality of care, decrease job satisfaction, and potentially increase medical errors. The aim of this study was to investigate the occupational stress and career satisfaction of Korean surgeons. We have conducted an electronic survey of 621 Korean surgeons for the occupational stress. Sixty-five questions were used to assess practical and personal characteristics and occupational stress using the Korean occupational stress scale (KOSS). The mean KOSS score was 49.31, which was higher than the average of Korean occupational stress (45.86) or that of other specialized professions (46.03). Young age, female gender, long working hours, and frequent night duties were significantly related to the higher KOSS score. Having spouse, having hobby and regular exercise decreased the KOSS score. Multiple linear regression analysis showed that long working hours and regular exercise were the independent factors associated with the KOSS score. Less than 50% of surgeons answered that they would become a surgeon again. Most surgeons (82.5%) did not want to recommend their child follow their career. Korean Surgeons have high occupational stress and low level of career satisfaction.

The 3D interior design software (3DIDS) is a technology, which primarily allows users to simulate their homes and visualize any changes prior to implementing them. This feasibility study aimed to examine occupational therapists' perceptions about the clinical utility of the 3DIDS. A secondary aim was to explore the attitudes of occupational therapists towards technology in general. Three focus groups were conducted with 25 occupational therapists working with older people in the UK. The qualitative data were analysed using inductive thematic analysis. The three main themes that were identified were usage and attitudes of technology, opportunities for realistic application of the 3DIDS and related threats and benefits for the occupational therapy profession. Occupational therapists had a positive attitude towards technology. They suggested that the 3DIDS could be used in discharge planning and in rehabilitation. They viewed it as a tool that could enhance their status within the health care profession and improve communication, but not as a tool that should replace the role of the occupational therapist. This research offers new and important findings about the utilization of the 3DIDS by occupational therapists and provides information as to where this technology should be trialled.

Modifying the home environments of older people as they age in place is a well-established health and social care intervention. Using design and construction methods to redress any imbalance caused by the ageing process or disability within the home environment, occupational therapists are seen as the experts in this field of practice. However, the process used by occupational therapists when modifying home environments has been criticised for being disorganised and not founded on theoretical principles and concepts underpinning the profession. To address this issue, research was conducted to develop a design and construction process protocol specifically for home modifications. A three-stage approach was taken for the analysis of qualitative data generated from an online survey, completed by 135 occupational therapists in the UK. Using both the existing occupational therapy intervention process model and the design and construction process protocol as the theoretical frameworks, a 4-phase, 9-subphase design and construction process protocol for home modifications was developed. Overall, the study is innovative in developing the first process protocol for home modifications, potentially providing occupational therapists with a systematic and effective approach to the design and delivery of home modification services for older and disabled people.

Registries are one strategy for collecting information on occupational exposure and disease in populations. Recently leaders in the Canadian occupational health and safety community have shown an interest in the use of occupational exposure registries. The primary goal of this study was to review a series of Canadian exposure registries to identify their strengths and weaknesses as a tool for tracking occupational exposure and disease in Canada. A secondary goal was to identify the features of an exposure registry needed to specifically contribute to prevention, including the identification of new exposure-disease relationships. A documentary review of five exposure registries from Canada was completed. Strengths and limitations of the registries were compared and key considerations for designing new registries were identified. The goals and structure of the exposure registries varied considerably. Most of the reviewed registries had voluntary registration, which presents challenges for the use of the data for either surveillance or epidemiology. It is recommended that eight key issues be addressed when planning new registries: clear registry goal(s), a definition of exposure, data to be collected (and how it will be used), whether enrolment will be mandatory, as well as ethical, privacy and logistical considerations. When well constructed, an exposure registry can be a valuable tool for surveillance, epidemiology and ultimately the prevention of occupational disease. However, exposure registries also have a number of actual and potential limitations that need to be considered.

Full Text Available Grid-based perception techniques in the automotive sector based on fusing information from different sensors and their robust perceptions of the environment are proliferating in the industry. However, one of the main drawbacks of these techniques is the traditionally prohibitive, high computing performance that is required for embedded automotive systems. In this work, the capabilities of new computing architectures that embed these algorithms are assessed in a real car. The paper compares two ad hoc optimized designs of the Bayesian Occupancy Filter; one for General Purpose Graphics Processing Unit (GPGPU and the other for Field-Programmable Gate Array (FPGA. The resulting implementations are compared in terms of development effort, accuracy and performance, using datasets from a realistic simulator and from a real automated vehicle.

The aim of this study was to investigate the relationships between occupational noise exposure and blood pressure using self-reported occupational exposure and bilateral high-frequency hearing loss. This study included 4548 participants aged 20 to 69 years from the National Health and Nutrition Examination Survey 1999 to 2004. On the basis of self-reported exposure status, participants were divided into the current, former, or never exposed groups. Bilateral high-frequency hearing loss was defined as the average high-frequency hearing threshold at least 25 dB in both ears. The currently exposed participants had slightly increased diastolic blood pressure compared with those never exposed. Among previously exposed participants, those with bilateral high-frequency hearing loss had increased systolic blood pressure, heart rate, and the prevalence of hypertension compared with those with normal high-frequency hearing. Although there were some significant results, the evidence was not consistent to support the associations between occupational noise exposure and blood pressure.

Curriculum-Level Strategies That U.S. Occupational Therapy Programs Use to Address Occupation: A Qualitative Study.

Hooper, Barb; Krishnagiri, Sheama; Price, Pollie; Taff, Steven D; Bilics, Andrea

This study's objective was to describe curriculum-level strategies used to convey occupation to occupational therapy students. The study used a descriptive qualitative research design. Fifteen occupational therapy and 10 occupational therapy assistant programs participated in interviews, submitted curriculum artifacts such as syllabi and assignments, and recorded teaching sessions. Data were coded both inductively and deductively and then categorized into themes. Occupational therapy programs designed strategies on two levels of the curriculum, infrastructure and implementation, to convey knowledge of occupation to students. The degree to which strategies explicitly highlighted occupation and steered instruction fluctuated depending on how differentiated occupation was from other concepts and skills. Two arguments are presented about the degree to which occupation needs to be infused in all curricular elements. To guide curriculum design, it is critical for educators to discuss beliefs about how ubiquitous occupation is in a curriculum and whether curricular elements portray occupation to the extent preferred.

Recently, the Occupational Therapy Department requested a custom-designed medical physiology course for the students in the new occupational therapy doctoral program. The first author, a physiologist with extensive experience in teaching both undergraduate preprofessional and medical students in human physiology, was recruited to design and implement the course. The course was designed to be consistent with the constructivist philosophy that guides the occupational therapy curriculum. The course was offered for the first time during fall/spring 2015/2016 and included both first- and second-year occupational therapy doctoral students. A number of anonymous assessment tools were used to evaluate students' perceptions regarding the effectiveness of various pedagogies used in the course in enhancing their learning. A summative course assessment survey with comments was used at the end of the course. This paper describes the model of course design and the student feedback, which generated some suggestions for improvement of the course. This approach in designing a new course for a new disciplinary group of students should be helpful to other faculty involved in developing courses for health career programs populated by students with variable physiology backgrounds and different educational needs. The final relevant feedback from the course would be to have the students evaluate the usefulness of the course to their future careers immediately following their certification examinations in a year or two and during their subsequent clinical experiences; however, that information will likely be more difficult to obtain.

Damage to the lungs caused by dusts or fumes or noxious substances inhaled by workers in certain specific occupation is known as occupational lung disease. Recognition of occupational lung disease is especially important not only for the primary worker, but also because of the implications with regard to primary and secondary disease prevention in the exposed co-workers. Although many of the disorders can be detected on chest radiography, high-resolution computed tomography (HRCT) is superior in delineating the lung architecture and depicting pathology. The characteristic radiological features suggest the correct diagnosis in some, whereas a combination of clinical features, occupational history, and radiological findings is essential in establishing the diagnosis in others. In the presence of a history of exposure and consistent clinical features, the diagnosis of even an uncommon occupational lung disease can be suggested by the characteristic described HRCT findings. In this article, we briefly review the HRCT appearance of a wide spectrum of occupational lung diseases.

Recommended survey designs for occupancy modelling using motion-activated cameras: insights from empirical wildlife data

Directory of Open Access Journals (Sweden)

Graeme Shannon

2014-08-01

Full Text Available 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

Kottarathil Eashy Mary Reena

2015-01-01

Full Text Available Cyber-physical system (CPS includes the class of Intelligent Building Automation System (IBAS which increasingly utilizes advanced technologies for long term stability, economy, longevity, and user comfort. However, there are diverse issues associated with wireless interconnection of the sensors, controllers, and power consuming physical end devices. In this paper, a novel architecture of CPS for wireless networked IBAS with priority-based access mechanism is proposed for zones in a large building with dynamically varying occupancy. Priority status of zones based on occupancy is determined using fuzzy inference engine. Nondominated Sorting Genetic Algorithm-II (NSGA-II is used to solve the optimization problem involving conflicting demands of minimizing total energy consumption and maximizing occupant comfort levels in building. An algorithm is proposed for power scheduling in sensor nodes to reduce their energy consumption. Wi-Fi with Elimination-Yield Nonpreemptive Multiple Access (EY-NPMA scheme is used for assigning priority among nodes for wireless channel access. Controller design techniques are also proposed for ensuring the stability of the closed loop control of IBAS in the presence of packet dropouts due to unreliable network links.

Full Text Available Background. This study examines how and why occupational therapy practitioners across practice areas use gardening as an intervention. Respondents’ interpretation of the best and least desirable aspects of their facility’s garden and whether they contributed to its design was also examined. Method. A description and link to a 15-question online survey about gardening as an occupational therapy intervention was emailed to Western Michigan University Occupational Therapy alumni and posted on four OT Connections groups and the AOTA LinkedIn site. Results. Gardening as an occupational therapy intervention is meaningful and purposeful (93.66%, n = 56, motivating (80%, n = 48, fun 61.67% (n = 37, and client-centered (31.67%, n =19. Frequency of gardening as a therapeutic intervention and practitioner involvement in designing the garden was significant (p = .007, suggesting that for respondents, environmental context supports engagement and heightens the meaningfulness and purposefulness of gardening. Conclusion. Based on results of this study, a suggested next step is evidence-based translational and intervention research to validate the efficacy of gardening as an occupational therapy intervention and occupational therapy practitioners’ professional value as implementers of such intervention. Assessing the effectiveness of the role of occupational therapy practitioners in facility garden design is also important to consider.

Exposures to beryllium (Be), even at extremely low levels, can cause severe health effects in a percentage of those exposed; consequently, occupational exposure limits (OELs) promulgated for this element are the lowest established for any element. This work describes the advantages of using highly alkaline dye solutions for determination of Be in occupational hygiene and environmental samples by means of an optical molecular fluorescence technique after sample extraction in 1-3% (w˖w -1 ) aqueous ammonium bifluoride (NH 4 HF 2 ). Improved attributes include the ability to further enhance the detection limits of Be in extraction solutions of high acidity with minimal dilution, which is particularly beneficial when NH 4 HF 2 solutions of higher concentration are used for extraction of Be from soil samples. Significant improvements in Be method detection limits (MDLs) are obtained at levels many-fold below those reported previously for this methodology. Notably, MDLs for Be of health organizations and regulatory agencies in the USA and internationally. Applications of enhanced Be measurements to air filter samples, surface wipe samples, soils and newly-designed occupational air sampler inserts are illustrated.

Cardiovascular diseases are among the most important sources of mortality and morbidity, and have a high disease burden. There are some major well-known risk factors, which contribute to the development of these diseases. Occupational stress is caused due to imbalance between job demands and individual's ability, and it has been implicated as an etiology for cardiovascular diseases. This study was conducted to evaluate the cardiovascular risk factors and different dimensions of occupational stress in high-ranking government officials, comparing an age and sex-matched group of office workers with them. We invited 90 high-ranking officials who managed the main governmental offices in a city, and 90 age and sex-matched office workers. The subjects were required to fill the occupational role questionnaire (Osipow) which evaluated their personal and medical history as well as occupational stress. Then, we performed physical examination and laboratory tests to check for cardiovascular risk factors. Finally, the frequency of cardiovascular risk factors and occupational stress of two groups were compared. High-ranking officials in our study had less work experience in their current jobs and smoked fewer pack-years of cigarette, but they had higher waist and hip circumference, higher triglyceride level, more stress from role overload and responsibility, and higher total stress score. Our group of office workers had more occupational stress because of role ambiguity and insufficiency, but their overall job stress was less than officials. The officials have higher scores in some dimensions of occupational stress and higher overall stress score. Some cardiovascular risk factors were also more frequent in managers.

Hees Hiske L

2010-09-01

Full Text Available Abstract Background Major depressive disorder is among the medical conditions with the highest negative impact on work outcome. However, little is known regarding evidence-based interventions targeting the improvement of work outcomes in depressed employees. In this paper, the design of a randomized controlled trial is presented in order to evaluate the effectiveness of adjuvant occupational therapy in employees with depression. This occupational intervention is based on an earlier intervention, which was designed and proven effective by our research group, and is the only intervention to date that specifically targets work outcome in depressed employees. Methods/Design In a two-arm randomized controlled trial, a total of 117 participants are randomized to either 'care as usual' or ' care as usual' with the addition of occupational therapy. Patients included in the study are employees who are absent from work due to depression for at least 25% of their contract hours, and who have a possibility of returning to their own or a new job. The occupational intervention consists of six individual sessions, eight group sessions and a work-place visit over a 16-week period. By increasing exposure to the working environment, and by stimulating communication between employer and employee, the occupational intervention aims to enhance self-efficacy and the acquisition of more adaptive coping strategies. Assessments take place at baseline, and at 6, 12, and 18-month follow-ups. Primary outcome measure is work participation (hours of absenteeism and time until work resumption. Secondary outcome measures are work functioning, symptomatology, health-related quality of life, and neurocognitive functioning. In addition, cost-effectiveness is evaluated from a societal perspective. Finally, mechanisms of change (intermediate outcomes and potential patient-treatment matching variables are investigated. Discussion This study hopes to provide valuable knowledge

A calculational methodology for comparing the accident, occupational, and waste-disposal hazards of fusion reactor designs

International Nuclear Information System (INIS)

Fetter, S.

1985-01-01

A methodology has been developed for calculating indices of three classes of radiological hazards: reactor accidents, occupational exposures, and waste-disposal hazards. Radionuclide inventories, biological hazard potentials (BHP), and various dose-related indices are calculated. In the case of reactor accidents, the critical, 50-year and chronic dose are computed, as well as the number of early deaths and illnesses and late cancer fatalities. For occupational exposure, the contact dose rate is calculated for several times after reactor shutdown. In the case of waste-disposal hazards, the intruder dose and the intruder hazard potential (IHP) are calculated. Sample calculations for the MARS reactor design show the usefulness of the methodology in exploring design improvements

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 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.

Women workers constitute one of the most vulnerable segments of the country's labour force. They often face different workplace health challenges than men do. They are engaged in a range of work that extends from heavy, monotonous, repetitive jobs, which are in many times experienced with low-paid and involves in long hours of work. Women's workplace health problems are frequently compounded by getting more of the same at home--the "double jeopardy" of domestic work. Specific issues to improve the workers motivation leading to enhancement of productivity and improving occupational health and safety were addressed. Context specific application of ergonomics principles were studied in the process of designing of work related equipment of local fruit processing units, as well as in tea industry, covering 180 subjects selected purposively. Ergonomic risk factors prevailed among the workers associates productivity and relevant health issues were quantified using QEC, RULA. NMQ was used to gather data on prevalence of CTDs among the workers. Pineapple peeling, tea leaves plucking were found highly labour intensive, done manually. Postures scores found were very high. WRMSDs were prevalent among the workers. Scope for ergonomic design intervention was observed to improve productivity and occupational health.

Dealing with trade-offs in destructive sampling designs for occupancy surveys.

Directory of Open Access Journals (Sweden)

Stefano Canessa

Full Text Available Occupancy surveys should be designed to minimise false absences. This is commonly achieved by increasing replication or increasing the efficiency of surveys. In the case of destructive sampling designs, in which searches of individual microhabitats represent the repeat surveys, minimising false absences leads to an inherent trade-off. Surveyors can sample more low quality microhabitats, bearing the resultant financial costs and producing wider-spread impacts, or they can target high quality microhabitats were the focal species is more likely to be found and risk more severe impacts on local habitat quality. We show how this trade-off can be solved with a decision-theoretic approach, using the Millewa Skink Hemiergis millewae from southern Australia as a case study. Hemiergis millewae is an endangered reptile that is best detected using destructive sampling of grass hummocks. Within sites that were known to be occupied by H. millewae, logistic regression modelling revealed that lizards were more frequently detected in large hummocks. If this model is an accurate representation of the detection process, searching large hummocks is more efficient and requires less replication, but this strategy also entails destruction of the best microhabitats for the species. We developed an optimisation tool to calculate the minimum combination of the number and size of hummocks to search to achieve a given cumulative probability of detecting the species at a site, incorporating weights to reflect the sensitivity of the results to a surveyor's priorities. The optimisation showed that placing high weight on minimising volume necessitates impractical replication, whereas placing high weight on minimising replication requires searching very large hummocks which are less common and may be vital for H. millewae. While destructive sampling methods are sometimes necessary, surveyors must be conscious of the ecological impacts of these methods. This study provides a

Towards inclusive occupational therapy: Introducing the CORE approach for inclusive and occupation-focused practice.

Science.gov (United States)

Pereira, Robert B

2017-12-01

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.

Future preparation of occupational health nurse managers.

Scalzi, C C; Wilson, D L; Ebert, R

1991-03-01

This article presents the results of a national survey of job activities of corporate level occupational health nurse managers. The survey was designed to identify the relative amount of time spent and importance attributed to specific areas of their current job. In general this sample tended to have more management experience and educational preparation than previously cited studies: over 50% had completed a graduate degree. The scores for importance and time spent were highly correlated. That is, occupational health corporate nurse managers seemed to allocate their time to job responsibilities they considered most important. Management activities related to policy, practice standards, quality assurance, staff development, and systems for client care delivery appear to represent the core responsibilities of occupational health nursing management. Curriculum recommendations for management positions in occupational health include: health policy, program planning, and evaluation; business strategy; applications of management information systems; quality assurance; and marketing.

Using occupancy models of forest breeding birds to prioritize conservation planning

As urban development continues to encroach on the natural and rural landscape, land-use planners struggle to identify high priority conservation areas for protection. Although knowing where urban-sensitive species may be occurring on the landscape would facilitate conservation planning, research efforts are often not sufficiently designed to make quality predictions at unknown locations. Recent advances in occupancy modeling allow for more precise estimates of occupancy by accounting for differences in detectability. We applied these techniques to produce robust estimates of habitat occupancy for a subset of forest breeding birds, a group that has been shown to be sensitive to urbanization, in a rapidly urbanizing yet biological diverse region of New York State. We found that detection probability ranged widely across species, from 0.05 to 0.8. Our models suggest that detection probability declined with increasing forest fragmentation. We also found that the probability of occupancy of forest breeding birds is negatively influenced by increasing perimeter-area ratio of forest fragments and urbanization in the surrounding habitat matrix. We capitalized on our random sampling design to produce spatially explicit models that predict high priority conservation areas across the entire region, where interior-species were most likely to occur. Finally, we use our predictive maps to demonstrate how a strict sampling design coupled with occupancy modeling can be a valuable tool for prioritizing biodiversity conservation in land-use planning. ?? 2009 Elsevier Ltd.

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.

Mustoe, J.; Currie, I.D.; Frias, M. Pascual

2001-01-01

As part of the SEAFP-99 programme, water cooled and helium cooled fusion power plant design concepts were assessed with regard to occupational doses and related availability and operating costs. Different design and management measures to reduce occupational doses were considered. This task assessed the existing designs and proposed extensions or changes, where required. For each significant contributor, possible methods were specified which could reduce the operator dose and outage time. Where this was the case expected; costs or savings incurred by the improvement were estimated. Overall, the use of a system to remove particulate corrosion product activity from the primary coolant was considered essential for the water-cooled variant. In addition, application of the most up-to-date ALARA techniques could make the estimated dose for the water-cooled conceptual design appreciably lower than earlier estimated. It was concluded that the water cooled conceptual design could meet the project design target for occupational dose of 0.7 p-Sv per GW(e). A survey of occupational doses from the UK AGR plants was also carried out. From this, it is judged that the helium cooled fusion plant conceptual design could meet the project design target for occupational dose of 0.7 p-Sv per GW(e) without the need for additional plant to reduce primary coolant activity levels

Objective: To investigate the relationship between occupational stress and working ability of workers in a petroleum processing enterprise in a high altitude area. Methods: A total of 728 workers in a petroleum processing enterprise at an altitude of 2850 m were subjected to a survey using Occupational Stress Inventory (OSI) , Work Ability Index (WAI) Scale, Occupational Role Questionnaire (ORQ) , Personal Strain Questionnaire (PSQ) , and Personal Resource Questionnaire (PRQ) from May 2014 to August 2016. Results: Of the 728 workers, 55 (7.6%) had a poor working ability, moderate in 262 (35.9%) , and good in 411 (56.5%). There were significant differences in WAI between the workers with different types of work, sexes, ages, and working years ( P occupational stress groups ( P Occupational stress is an influencing factor for the working ability of workers in the petroleum processing enterprise in the high altitude area. Hypoxia in high altitude area may further reduce the working ability. In order to reduce occupational stress and improve work ability, it should be considered to strengthen skills training, improve the working environment, and pay attention to mental health.

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.

Full Text Available To explore factors associated with occupational sex segregation in the United States over the past four decades, we analyzed U.S. Bureau of Labor Statistics data for the percent of women employed in 60 varied occupations from 1972 to 2010. Occupations were assessed on status, people-things orientation, and data-ideas orientation. Multilevel linear modeling (MLM analyses showed that women increasingly entered high-status occupations from 1972 to 2010, but women's participation in things-oriented occupations (e.g., STEM fields and mechanical and construction trades remained low and relatively stable. Occupations' data-ideas orientation was not consistently related to sex segregation. Because of women's increased participation in high-status occupations, occupational status became an increasingly weak predictor of women's participation rates in occupations, whereas occupations' people-things orientation became an increasingly strong predictor over time. These findings are discussed in relation to theories of occupational sex segregation and social policies to reduce occupational sex segregation.

Full Text Available Background: Occupational stress and associated physical and mental health related issues are not addressed in Indian police personnel with adequate importance. Methods: Cross-sectional survey was conducted among police personnel (both male and female in Calicut urban police district, Kerala state, India. Police personnel from all designations (ranks, except from the all India services (Indian Police Service were included in the study. Data were collected using a specifically designed datasheet covering socio-demographic profile, physical and mental health related details which was prepared by researchers. Occupational stress was measured using Operational Police Stress Questionnaire (PSQ-OP and Organisational Police Stress Questionnaire (PSQ-ORG. Result: The study found that both operational and organisational stress was significant among the police officers. Organisational stress was experienced in moderate level by 68% and in high level by 14%. Operational stress scores were in the moderate range in 67% and in high range in 16.5%. The younger age group (21-35 years and lower level rank police personnel had higher stress. Stress was higher among female police personnel compared to males. While 23% of them had been diagnosed with physical illnesses, a significant four per cent of them with mental illness, and 29% of them reported substance abuse. Conclusion: The results point to the high level of stress among Indian police personnel and the need for urgent interventions from the government to address the occupational stress.

The aim of this study was to compute attributable fractions (AF) to occupational factors in an area in North-Eastern France with high lung cancer rates and a past of mining and steel industry. A population-based case-control study among males aged 40-79 was conducted, including confirmed primary lung cancer cases from all hospitals of the study region. Controls were stratified by broad age-classes, district and socioeconomic classes. Detailed occupational and personal risk factors were obtained in face-to-face interviews. Cumulative occupational exposure indices were obtained from the questionnaires. Attributable fractions were computed from multiple unconditional logistic regression models. A total of 246 cases and 531 controls were included. The odds ratios (ORs) adjusted on cumulative smoking and family history of lung cancer increased significantly with the cumulative exposure indices to asbestos, polycyclic aromatic hydrocarbons and crystalline silica, and with exposure to diesel motor exhaust. The AF for occupational factors exceeded 50%, the most important contributor being crystalline silica and asbestos. These AFs are higher than most published figures. This can be because of the highly industrialised area or methods for exposure assessments. Occupational factors are important risk factors and should not be forgotten when defining high-risk lung cancer populations.

Early incidence of occupational asthma among young bakers, pastry-makers and hairdressers: design of a retrospective cohort study

Guéant-Rodriguez Rosa-Maria

2010-04-01

Full Text Available Abstract Background Occupational exposures are thought to be responsible for 10-15% of new-onset asthma cases in adults, with disparities across sectors. Because most of the data are derived from registries and cross-sectional studies, little is known about incidence of occupational asthma (OA during the first years after inception of exposure. This paper describes the design of a study that focuses on this early asthma onset period among young workers in the bakery, pastry making and hairdressing sectors in order to assess early incidence of OA in these "at risk" occupations according to exposure duration, and to identify risk factors of OA incidence. Methods/Design The study population is composed of subjects who graduated between 2001 and 2006 in these sectors where they experience exposure to organic or inorganic allergenic or irritant compounds (with an objective of 150 subjects by year and 250 young workers with no specific occupational exposure. A phone interview focusing on respiratory and 'Ear-Nose-Throat' (ENT work-related symptoms screen subjects considered as "possibly OA cases". Subjects are invited to participate in a medical visit to complete clinical and lung function investigations, including fractional exhaled nitric oxide (FENO and carbon monoxide (CO measurements, and to collect blood samples for IgE (Immunoglobulin E measurements (total IgE and IgE for work-related and common allergens. Markers of oxidative stress and genetic polymorphisms exploration are also assessed. A random sample of 200 "non-cases" (controls is also visited, following a nested case-control design. Discussion This study may allow to describ a latent period between inception of exposure and the rise of the prevalence of asthma symptoms, an information that would be useful for the prevention of OA. Such a time frame would be suited for conducting screening campaigns of this emergent asthma at a stage when occupational hygiene measures and adapted

Sampling scales define occupancy and underlying occupancy-abundance relationships in animals.

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

Occupation and the relevance of primatology to occupational therapy.

Science.gov (United States)

Wood, W

1993-06-01

The adaptive functions of occupation during the phylogenetic history of the human species and the ontogenetic development of individual primates re examined through a review of relevant research of wild and captive nonhuman primates. This review suggests that the effectiveness of occupation as a therapeutic medium throughout life span development is fundamentally tied to humankind's phylogenetic history. It is accordingly argued that there is considerable justification to maintain occupational therapy's historical commitment to therapeutic occupation as the profession's primary treatment modality. To support this commitment, questions to guide practice and research are identified that emanate from the primate literature and that are highly germane to the therapeutic process in occupational therapy. These questions address: (a) the relationship between the press of the various environments in which occupational therapists practice and subsequent opportunities availed to patients for engagement in occupation; (b) the relationship between the extent to which patients are or are not empowered to exert real control over their use of time and their eventual development of disabling conditions; and (c) the therapeutic efficacy of occupation as compared with other treatment approaches that are not comparably holistic.

Schindler, Victoria P

2010-09-01

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.

Building owners, designers and occupants need to consider all the design measures that contribute to high indoor air quality. Building occupants, furnishings, equipment, and ambient air pollution all contribute to surmounting indoor air quality concerns. However, these can be minimized by following HVAC design guidelines which promote high indoor air quality while maintaining reasonable energy-efficiency. The possible liabilities and loss of business productivity due to air quality problems are too great to ignore

Ten to thirty percent of lung cancer is thought to be of occupational origin. Lung cancer is under-declared as an occupational disease in Europe, and most declarations of occupational disease concern asbestos. The purpose of this study was to design and validate a short, sensitive self-administered questionnaire, as an aid for physicians in detecting occupational exposure to asbestos and other lung carcinogens in order to remedy occupational lung cancer under-declaration. Cross-sectional study. A short (30-question) self-administered questionnaire was drawn up by oncologist-pneumologists and occupational physicians, covering situations of exposure to proven and probable lung carcinogens. Understanding and acceptability were assessed on 15 lung cancer patients. Validity and reliability were assessed on 70 lung cancer patients by comparison against a semi-directive questionnaire considered as gold standard. Sensitivity and specificity were assessed by comparing responses to items on the two questionnaires. Reliability was assessed by analysing the kappa concordance coefficient for items on the two questionnaires. Sensitivity was 0.85 and specificity 0.875. Concordance between responses on the two questionnaires was 85.7%, with a kappa coefficient of 0.695 [0.52-0.87]. Mean self-administration time was 3.1 min (versus 8.12 min to administer the gold-standard questionnaire). In 16 patients, the self-administered questionnaire detected lung carcinogen exposure meeting the criteria for occupational disease. The present short, easy-to-use self-administered questionnaire should facilitate detection of occupational exposure to lung carcinogens. It could be used in occupational lung cancer screening and increase the presently low rate of application for recognition of lung cancer as an occupational disease.

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

Coupled force-balance and particle-occupation rate equations for high-field electron transport

International Nuclear Information System (INIS)

Lei, X. L.

2008-01-01

It is pointed out that in the framework of balance-equation approach, the coupled force-balance and particle-occupation rate equations can be used as a complete set of equations to determine the high-field transport of semiconductors in both strong and weak electron-electron interaction limits. We call to attention that the occupation rate equation conserves the total particle number and maintains the energy balance of the relative electron system, and there is no need to introduce any other term in it. The addition of an energy-drift term in the particle-occupation rate equation [Phys. Rev. B 71, 195205 (2005)] is physically inadequate for the violation of the total particle-number conservation and the energy balance. It may lead to a substantial unphysical increase of the total particle number by the application of a dc electric field

Full Text Available Quality of product design, which is expected from manufacturers on world market these days, could be provided exclusively by integral approach to product design. Such approach aims to achievement of optimal design solution of product, which is in line with a number of requirements, conditions and limitations of functionality, technology, market and usage. Only those manufacturers who are able to provide such approach to product design have prospective on market. This paper deals with a case study of neglect of integral approach to product design and its consequencies, in order to spread awareness of necessity of its adoption. Scope of this case study is focused on bridge crane whose working vibrations are meant to be potential cause of occupational desease of spinal column of crane operator.

Play and play occupation: a survey of paediatric occupational therapy practice in Ireland

Full Text Available Purpose - Play occupation has been identified as an essential part of children’s lives, and it subsequently features in paediatric occupational therapy. However, few studies address the current place of play and play occupation in occupational therapy practice. This study aims to address this gap in knowledge by exploring paediatric occupational therapists’ perspectives on the place of play and play occupation in occupational therapy practice in Ireland. Design/methodology/approach - A cross-sectional online survey was conducted to gather data about the current use of play in the occupational therapy for children under 12 years. Convenience sampling and snowball recruitment techniques were used to recruit paediatric occupational therapists. Data were analysed using descriptive statistics and qualitative content analysis. Findings - In total, 65 therapists responded to the survey (estimated response rate, 32%. Results are organised into four sections: demographics and practice context, play assessment practices, use of play in practice and perceived barriers to play-centred practice. Respondents reported that they valued play as a childhood occupation. However, the survey findings identified that the primary focus was on play as a means to an end. Lack of education on play (research, theory and interventions and pressures in the workplace have been identified as barriers to play-centred practice. Research limitations/implications - Findings indicate that there is a mismatch between therapists valuing play as an occupation and how play is used in occupational therapy practice. Unless clarifications are made about play occupation as being different to skills acquisition in childhood, play occupation will continue to get overlooked as an authentic concern of occupation-centred practice. Thus, play as occupation deserves further attention from educators, researchers and practitioners as a means of strengthening occupation-centred practice, in

1. Recent advances in occupancy estimation that adjust for imperfect detection have provided substantial improvements over traditional approaches and are receiving considerable use in applied ecology. To estimate and adjust for detectability, occupancy modelling requires multiple surveys at a site and requires the assumption of 'closure' between surveys, i.e. no changes in occupancy between surveys. Violations of this assumption could bias parameter estimates; however, little work has assessed model sensitivity to violations of this assumption or how commonly such violations occur in nature. 2. We apply a modelling procedure that can test for closure to two avian point-count data sets in Montana and New Hampshire, USA, that exemplify time-scales at which closure is often assumed. These data sets illustrate different sampling designs that allow testing for closure but are currently rarely employed in field investigations. Using a simulation study, we then evaluate the sensitivity of parameter estimates to changes in site occupancy and evaluate a power analysis developed for sampling designs that is aimed at limiting the likelihood of closure. 3. Application of our approach to point-count data indicates that habitats may frequently be open to changes in site occupancy at time-scales typical of many occupancy investigations, with 71% and 100% of species investigated in Montana and New Hampshire respectively, showing violation of closure across time periods of 3 weeks and 8 days respectively. 4. Simulations suggest that models assuming closure are sensitive to changes in occupancy. Power analyses further suggest that the modelling procedure we apply can effectively test for closure. 5. Synthesis and applications. Our demonstration that sites may be open to changes in site occupancy over time-scales typical of many occupancy investigations, combined with the sensitivity of models to violations of the closure assumption, highlights the importance of properly addressing

To study job stress and upper limb biomechanical overload due to repetitive and forceful manual activities in a factory producing high fashion clothing. A total of 518 workers (433 women and 85 men) were investigated to determine anxiety, occupational stress (using the Italian version of the Karasek Job Content Questionnaire) and perception of symptoms (using the Italian version of the Somatization scale of Symptom Checklist SCL-90). Biomechanical overload was analyzed using the OCRA Check list. Biomechanical assessment did not reveal high-risk jobs, except for cutting. Although the perception of anxiety and job insecurity was within the normal range, all the workers showed a high level of job strain (correlated with the perception of symptoms) due to very low decision latitude. Occupational stress resulted partially in line with biomechanical risk factors; however, the perception of low decision latitude seems to play a major role in determining job strain. Interactions between physical and psychological factors cannot be demonstrated. Anyway, simultaneous long-term monitoring of occupational stress features and biomechanical overload could guide workplace interventions aimed at reducing the risk of adverse health effects.

[Fatal occupational accidents in Lombardy].

Pianosi, G

1995-01-01

All fatal occupational accidents compensated in Lombardy from 1984 to 1989 were analyzed (1259 cases): significant differences between geographical distribution of fatal occupational accidents and workers were observed. Males accounted for about 95% of fatalities; an excess of cases was shown in both young and elderly workers. Death was the consequence of injuries involving most frequently the head, thorax and spinal cord. An excess of fatalities was observed in agriculture and, at a lower level, in manufacturing industries; small enterprises were involved in approximately 25% of fatalities occurring in the manufacturing industries and services. Employers were the victims of fatal accidents in 50% of cases in agriculture and in 70% of cases in craft industries. Construction, agriculture and transport accounted for about 50% of all fatalities. About 50% of fatal occupational accidents were related to vehicle use: the victim was the driver in the majority of cases, sometimes the victim was run over by a vehicle or fell from a vehicle. The results agree with some previous observations (e.g.: sex and age distribution; construction, agriculture and transport as working activities at high accident risk); but some original observations have emerged, in particular about the frequency of employers as victims and the role of vehicles in the genesis of fatal occupational accidents. If further studies confirm these latter observations, important developments could follow in preventive action design and implementation.

Are Biophilic-Designed Site Office Buildings Linked to Health Benefits and High Performing Occupants?

Directory of Open Access Journals (Sweden)

Tonia Gray

2014-11-01

Full Text Available This paper discusses the first phase of a longitudinal study underway in Australia to ascertain the broad health benefits of specific types of biophilic design for workers in a building site office. A bespoke site design was formulated to include open plan workspace, natural lighting, ventilation, significant plants, prospect and views, recycled materials and use of non-synthetic materials. Initial data in the first three months was gathered from a series of demographic questions and from interviews and observations of site workers. Preliminary data indicates a strong positive effect from incorporating aspects of biophilic design to boost productivity, ameliorate stress, enhance well-being, foster a collaborative work environment and promote workplace satisfaction, thus contributing towards a high performance workspace. The longitudinal study spanning over two years will track human-plant interactions in a biophilic influenced space, whilst also assessing the concomitant cognitive, social, psychological and physical health benefits for workers.

Born to Lead? A Twin Design and Genetic Association Study of Leadership Role Occupancy*

De Neve, Jan-Emmanuel; Mikhaylov, Slava; Dawes, Christopher T.; Christakis, Nicholas A.; Fowler, James H.

2013-01-01

We address leadership emergence and the possibility that there is a partially innate predisposition to occupy a leadership role. Employing twin design methods on data from the National Longitudinal Study of Adolescent Health, we estimate the heritability of leadership role occupancy at 24%. Twin studies do not point to specific genes or neurological processes that might be involved. We therefore also conduct association analysis on the available genetic markers. The results show that leadership role occupancy is associated with rs4950, a single nucleotide polymorphism (SNP) residing on a neuronal acetylcholine receptor gene (CHRNB3). We replicate this family-based genetic association result on an independent sample in the Framingham Heart Study. This is the first study to identify a specific genotype associated with the tendency to occupy a leadership position. The results suggest that what determines whether an individual occupies a leadership position is the complex product of genetic and environmental influences; with a particular role for rs4950.

Objective The purpose of this study is to determine the relationship between occupational exposures and hearing among elderly Latino Americans. Design A descriptive, correlational design used for this secondary analysis with the data from the Sacramento Area Latino Study of Aging (SALSA). Study sample A total of 547 older adults were included. Results A majority of participants (58%) reported occupational exposures to loud noise and/or ototoxic chemicals. About 65% and over 90% showed hearing loss at low and high frequencies, respectively. Participants with occupational exposure to loud noise and/or ototoxic chemicals were, significantly, two times more likely to have hearing loss at high frequencies compared to those without exposure (OR = 2.29; 95% CI: 1.17 – 4.51, p = .016), after controlling for other risk factors of hearing loss such as age, gender, household income, current smoking, and diabetes. However, lifelong occupational exposure was not significantly associated with hearing loss at low frequencies (OR = 1.43; 95% CI: 0.94 – 2.18, p = .094). Conclusion Lifelong occupational exposure to loud noise and/or ototoxic chemicals was significantly associated with hearing loss among elderly Latino Americans. Healthy work life through protection from harmful auditory effects of occupational exposures to noise and chemicals will have a positive impact on better hearing in later life. PMID:25549170

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.

: High patient satisfaction is a desirable goal in medical care. Patient satisfaction measures are increasingly used to evaluate and improve quality in all types of medical practices. However, the unique aspects of occupational and environmental medicine (OEM) practice require development of OEM-specific measures and thoughtful interpretation of results. The American College of Occupational and Environmental Medicine has developed and recommends a set of specific questions to measure patient satisfaction in OEM, designed to meet anticipated regulatory requirements, facilitate quality improvement of participating OEM practices, facilitate case-management review, and offer fair and accurate assessment of OEM physicians.

Occupational exposures are thought to be responsible for 10-15% of new-onset asthma cases in adults, with disparities across sectors. Because most of the data are derived from registries and cross-sectional studies, little is known about incidence of occupational asthma (OA) during the first years after inception of exposure. This paper describes the design of a study that focuses on this early asthma onset period among young workers in the bakery, pastry making and hairdressing sectors in order to assess early incidence of OA in these "at risk" occupations according to exposure duration, and to identify risk factors of OA incidence. The study population is composed of subjects who graduated between 2001 and 2006 in these sectors where they experience exposure to organic or inorganic allergenic or irritant compounds (with an objective of 150 subjects by year) and 250 young workers with no specific occupational exposure. A phone interview focusing on respiratory and 'Ear-Nose-Throat' (ENT) work-related symptoms screen subjects considered as "possibly OA cases". Subjects are invited to participate in a medical visit to complete clinical and lung function investigations, including fractional exhaled nitric oxide (FENO) and carbon monoxide (CO) measurements, and to collect blood samples for IgE (Immunoglobulin E) measurements (total IgE and IgE for work-related and common allergens). Markers of oxidative stress and genetic polymorphisms exploration are also assessed. A random sample of 200 "non-cases" (controls) is also visited, following a nested case-control design. This study may allow to describ a latent period between inception of exposure and the rise of the prevalence of asthma symptoms, an information that would be useful for the prevention of OA. Such a time frame would be suited for conducting screening campaigns of this emergent asthma at a stage when occupational hygiene measures and adapted therapeutic interventions might be effective.

Full Text Available Simulation experiences provide experiential learning opportunities during artificially produced real-life medical situations in a safe environment. Evidence supports using simulation in health care education yet limited quantitative evidence exists in occupational therapy. This study aimed to evaluate the differences in scores on the AOTA Fieldwork Performance Evaluation for the Occupational Therapy Student of Level II occupational therapy students who received high-fidelity simulation training and students who did not. A retrospective analysis of 180 students from a private university was used. Independent samples nonparametric t tests examined mean differences between Fieldwork Performance Evaluation scores of those who did and did not receive simulation experiences in the curriculum. Mean ranks were also analyzed for subsection scores and practice settings. Results of this study found no significant difference in overall Fieldwork Performance Evaluation scores between the two groups. The students who completed simulation and had fieldwork in inpatient rehabilitation had the greatest increase in mean rank scores and increases in several subsections. The outcome measure used in this study was found to have limited discriminatory capability and may have affected the results; however, this study finds that using simulation may be a beneficial supplement to didactic coursework in occupational therapy curriculums.

Occupational health programme for lead workers in battery plants

Science.gov (United States)

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.

When high-energy photon beams are used for irradiation in radiotherapy, neutrons that are the result of photonuclear reactions create activation products that affect the occupational dose of radiotherapy staff. For the assessment of activation products in situ gamma spectroscopy was performed parallel to dose-rate measurements following irradiation, by using a high-energy photon beam from a linear accelerator Elekta Precise (Elekta, Stockholm (Sweden)) used in radiotherapy. The major identified activation products were the following radioisotopes: 2 '8Al, 24 Na, 56 Mn, 5 4 M n, 187 W, 64 Cu and 62 Cu. Based on the typical workload and dose-rate measurement, the assessed additional annual occupational dose ranged from 1.7 to 0.25 mSv. As the measured dose rate arising from the activation products rapidly decreases as a function of time, the assessed additional dose is negligible after 10 min following irradiation. To keep the occupational dose as low as reasonably achievable, it is recommended to delay entrance to the therapy room at least 2-4 min, when high-energy photons are used. This would reduce the effective dose by 30 %. (authors)

2017-03-01

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.

Full Text Available One of the most prominent contemporary trends in formation of companies is the approach to development of a customer-oriented company. In this matter, various versions related to the intensity of this orientation are differentiated. Customer relationship management (CRM system is a well-known concept, and its practice is being studied and improved in connection to various sectors. Companies providing services of occupational safety and health (OHS mainly cooperate with a large number of customers and the quality of this cooperation largely affects the occupational safety and health of employees. Therefore, it is of both scientific and wider social interest to study and improve the relationship of these companies with their customers. This paper investigates the practice of applying CRM in Croatian OHS companies. It identifies the existing conditions and suggests possible improvements in the practice of CRM, based on experts’ assessments using analytic hierarchy process evaluation. Universal preliminary design was created as a framework concept for the formation of a typical customer-oriented OHS services company. Preliminary design includes a structural view, which provides more details through system diagrams, and an illustration of main cooperation processes of a company with its customer.

Federal regulations in the United States require vehicles to meet occupant performance requirements with unbelted test dummies. Removing the test requirements with unbelted occupants might encourage the deployment of seat belt interlocks and allow restraint optimization to focus on belted occupants. The objective of this study is to compare the performance of restraint systems optimized for belted-only occupants with those optimized for both belted and unbelted occupants using computer simulations and field crash data analyses. In this study, 2 validated finite element (FE) vehicle/occupant models (a midsize sedan and a midsize SUV) were selected. Restraint design optimizations under standardized crash conditions (U.S.-NCAP and FMVSS 208) with and without unbelted requirements were conducted using Hybrid III (HIII) small female and midsize male anthropomorphic test devices (ATDs) in both vehicles on both driver and right front passenger positions. A total of 10 to 12 design parameters were varied in each optimization using a combination of response surface method (RSM) and genetic algorithm. To evaluate the field performance of restraints optimized with and without unbelted requirements, 55 frontal crash conditions covering a greater variety of crash types than those in the standardized crashes were selected. A total of 1,760 FE simulations were conducted for the field performance evaluation. Frontal crashes in the NASS-CDS database from 2002 to 2012 were used to develop injury risk curves and to provide the baseline performance of current restraint system and estimate the injury risk change by removing the unbelted requirement. Unbelted requirements do not affect the optimal seat belt and airbag design parameters in 3 out of 4 vehicle/occupant position conditions, except for the SUV passenger side. Overall, compared to the optimal designs with unbelted requirements, optimal designs without unbelted requirements generated the same or lower total injury risks for

McCombie, Randy P; Antanavage, Meredith E

2017-04-01

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.

The majority of post-acute hip fracture rehabilitation in the US is delivered in skilled nursing facilities (SNFs). Currently, there are limited guidelines that equip occupational and physical therapy practitioners with a summary of what constitutes evidence-based high quality rehabilitation. Thus, this study aimed to identify rehabilitation practitioners' perspectives on the practices that constitute high quality hip fracture rehabilitation. Focus groups were conducted with 99 occupational and physical therapy practitioners working in SNFs in southern California. Purposive sampling of facilities was conducted to capture variation in key characteristics known to impact care delivery for this patient population (e.g., financial resources, staffing, and patient case-mix). Questions aimed to elicit practitioners' perspectives on high quality hip fracture rehabilitation practices. Each session was audio-recorded and transcribed. Data were systematically analyzed using a modified grounded theory approach. Seven themes emerged: objectives of care; first 72 h; positioning, pain, and precautions; use of standardized assessments; episode of care practices; facilitating insight into progress; and interdisciplinary collaboration. Clinical guidelines are critical tools to facilitate clinical decision-making and achieve desired patient outcomes. The findings of this study highlight the practitioners' perspective on what constitutes high quality hip fracture rehabilitation. This work provides critical information to advance the development of stakeholder-driven rehabilitation clinical guidelines. Future research is needed to verify the findings from other stakeholders (e.g., patients), ensure the alignment of our findings with current evidence, and develop measures for evaluating their delivery and relationship to desired outcomes.

In the course of system design, many decisions must be made concerning different aspects of that particular system. The design of systems and components in a nuclear power plant has the added faction of occupational exposure experienced as a result of that design. This paper will deal with the different methods available to factor occupational exposure into design decisions. The ultimate goal is to have exposures related to the design 'As Low As Reasonably Achievable' or ALARA. To do this an analysis should be performed to show that the cost of reducing exposures any further cannot be justified in a cost-benefit analysis. In this paper examples will be given that will show that it is possible to change to a design which would increase occupational exposure somewhat but would increase the benefit over the cost of the extra exposure received. It will also be shown that some changes in design or additional equipment could be justified due to a reduction in exposure while some changes could not be justified on a reduction in exposure aspect alone but are justified on a time saving aspect such as during a refueling outage.

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.

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.

Full Text Available Self-report data suggests a large proportion of total physical activity (PA occurs at work. However, adults with higher levels of occupational PA may compensate by engaging in less non-occupational PA. The study aims were to 1 estimate the intensity, volume, and duration of PA in American adults that occurs at work, and 2 determine if those more active at work are less active outside of work. A cross-sectional sample of full-time employed adults (N=510 was recruited from Georgia city and county governments in 2013–2015. Participants wore an Actigraph GT3X+ accelerometer for two weeks. In 2016, for 442 participants with complete data including work schedules and self-reported job titles, accelerometer wear minutes were classified as either occupational or non-occupational, and as sedentary, LPA (light-intensity PA, or MVPA (moderate-to-vigorous intensity PA. The proportion of daily PA that occurred during work was 41.2% for total PA, 41.0% for LPA, and 39.5% for MVPA. Higher levels of occupational LPA were associated with lower levels of non-occupational LPA (r=−0.38, P<0.0001. However, higher levels of occupational MVPA were associated with higher levels of non-occupational MVPA (r=0.17, P<0.0001. These associations remained significant in a MANOVA adjusting for labor sector and other covariates. On average, employed adults get more LPA and MVPA outside of work. Adults who do more occupational MVPA do not compensate by doing less non-occupational MVPA. In contrast, adults who do more occupational LPA do compensate by doing less non-occupational LPA. Evaluations of interventions to reduce sedentary behavior should be designed to detect compensation effects. Keywords: Intensity, Work, Accelerometer

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.

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.

2014-12-01

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.

Painters are exposed to an extensive variety of harmful substances like aromatic hydrocarbons used as solvents and paint removers, some of which have shown clastogenic activity. These substances constitute a complex mixture of chemicals which contain well-known genotoxicants, such as Benzene, Toluene and Xylene. Thus, chronic occupational exposure to such substances may be considered to possess genotoxic risk. In Colombia the information available around the genotoxic damage (Chromosomal and DNA damage) in car paint shop workers is limited and the knowledge of this damage could contribute not only to a better understanding of the carcinogenic effect of this kind of substances but also could be used as biomarkers of occupational exposure to genotoxic agents. In this study, the genotoxic effect of aromatic hydrocarbons was assessed in peripheral blood lymphocytes of 24 workers occupationally exposed and 24 unexposed donors, by using Cytogenetic analysis and comet assay. A high frequency of Chromosomal alterations was found in the exposed group in comparison with those observed in the unexposed group. Among the total of CAs observed in the exposed group, fragilities were most frequently found (100 %), followed by chromosomal breaks (58 %), structural (41.2 %) and numerical chromosomal alterations (21 %). Numerical chromosomal alterations, fragilities and chromosomal breaks showed significant differences between exposed and unexposed groups. Among the fragilities, fra(9)(q12) was the most frequently observed. DNA damage index was also significantly higher in the exposed group compared to the unexposed group (p car paint shops workers and are also indicative of high chromosomal instability. The high frequency of both Chromosomal Alterations and DNA Damage Index observed in this study indicates an urgent need of intervention not only to prevent the increased risk of developing cancer but also to the application of strict health control and motivation to the use of

Sakowski, Piotr

2012-03-01

The study aimed at assessment of the Polish occupational medicine service system after over ten years of functioning in the current shape, made by occupational nurses. The article focuses on the job satisfaction level among Polish occupational medicine nurses. The survey was performed among 600 randomly selected occupational medicine nurses, registered in the regional occupational medicine centers. A questionnaire, designed by the research team, containing several questions concerning different aspects of OMS system assessment, including a part dedicated to job satisfaction assessment, was sent to the selected occupational nurses. The response rate was 33.3% (200 questionnaires). The survey shows a relatively high satisfaction level in case of five out of eleven investigated job aspects, and a very low satisfaction level in case of two of them ("Possibility of professional promotion", "Salary"). 26% of the OMS nurses had considered going abroad to work as a nurse in the general health care system, and 17% in the OHS system. Almost 25% of them would not choose a profession of an occupational nurse once again, including 10% who would not choose a nurse job at all. There is a statistically significant correlation between the general job satisfaction and satisfaction with other aspects of nursing work. A strong correlation was observed in case of "Scope of performed tasks" and "Cooperation with employers (clients of the occupational medicine service units)". There is a statistically significant correlation of average strength between the decision concerning choosing an occupational nurse job in case of taking a decision on professional carrier once again and "General job satisfaction". Polish occupational nurses are satisfied with their job, however only 26% are fully satisfied. In their work there is place for improvement. The areas which definitely need attention and improvement are "Possibility of professional promotion" and "Salary". Improvements in cooperation

Overcoming barriers to high performance seismic design using lessons learned from the green building industry

Science.gov (United States)

Glezil, Dorothy

NEHRP's Provisions today currently governing conventional seismic resistant design. These provisions, though they ensure the life-safety of building occupants, extensive damage and economic losses may still occur in the structures. This minimum performance can be enhanced using the Performance-Based Earthquake Engineering methodology and passive control systems like base isolation and energy dissipation systems. Even though these technologies and the PBEE methodology are effective reducing economic losses and fatalities during earthquakes, getting them implemented into seismic resistant design has been challenging. One of the many barriers to their implementation has been their upfront costs. The green building community has faced some of the same challenges that the high performance seismic design community currently faces. The goal of this thesis is to draw on the success of the green building industry to provide recommendations that may be used overcome the barriers that high performance seismic design (HPSD) is currently facing.

Occupational Trends and Program Priorities

Full Text Available Institutions of higher education that respond to the economic base in their region will remain competitive and be better positioned to obtain public funds and donor support. In addition to mandated program viability standards based on measures such as graduation rate, individual institutions and state coordinating boards can use ten-year occupational trend data to assess future program viability. We used an occupational demand model to determine whether academic programs can meet projected statewide needs for high demand and high growth occupations. For example, computer engineering, the highest growth rate occupation in Alabama, is projected to have 365 annual average job openings, with 93.6% total growth over ten years. But only 46 computer engineering majors graduate annually from all Alabama institutions of higher education. We recommend using an occupational demand model as a planning tool, decision-making tool, and catalyst for collaborative initiatives.

A technical framework to describe occupant behavior for building energy simulations

Energy Technology Data Exchange (ETDEWEB)

Turner, William; Hong, Tianzhen

2013-12-20

Green buildings that fail to meet expected design performance criteria indicate that technology alone does not guarantee high performance. Human influences are quite often simplified and ignored in the design, construction, and operation of buildings. Energy-conscious human behavior has been demonstrated to be a significant positive factor for improving the indoor environment while reducing the energy use of buildings. In our study we developed a new technical framework to describe energy-related human behavior in buildings. The energy-related behavior includes accounting for individuals and groups of occupants and their interactions with building energy services systems, appliances and facilities. The technical framework consists of four key components: i. the drivers behind energy-related occupant behavior, which are biological, societal, environmental, physical, and economical in nature ii. the needs of the occupants are based on satisfying criteria that are either physical (e.g. thermal, visual and acoustic comfort) or non-physical (e.g. entertainment, privacy, and social reward) iii. the actions that building occupants perform when their needs are not fulfilled iv. the systems with which an occupant can interact to satisfy their needs The technical framework aims to provide a standardized description of a complete set of human energy-related behaviors in the form of an XML schema. For each type of behavior (e.g., occupants opening/closing windows, switching on/off lights etc.) we identify a set of common behaviors based on a literature review, survey data, and our own field study and analysis. Stochastic models are adopted or developed for each type of behavior to enable the evaluation of the impact of human behavior on energy use in buildings, during either the design or operation phase. We will also demonstrate the use of the technical framework in assessing the impact of occupancy behavior on energy saving technologies. The technical framework presented is

Evaluating an Organizational-Level Occupational Health Intervention in a Combined Regression Discontinuity and Randomized Control Design.

Sørensen, By Ole H

2016-10-01

Organizational-level occupational health interventions have great potential to improve employees' health and well-being. However, they often compare unfavourably to individual-level interventions. This calls for improving methods for designing, implementing and evaluating organizational interventions. This paper presents and discusses the regression discontinuity design because, like the randomized control trial, it is a strong summative experimental design, but it typically fits organizational-level interventions better. The paper explores advantages and disadvantages of a regression discontinuity design with an embedded randomized control trial. It provides an example from an intervention study focusing on reducing sickness absence in 196 preschools. The paper demonstrates that such a design fits the organizational context, because it allows management to focus on organizations or workgroups with the most salient problems. In addition, organizations may accept an embedded randomized design because the organizations or groups with most salient needs receive obligatory treatment as part of the regression discontinuity design.

The aim of this study was to learn from a wide range of hospital staff members about how the design of the patient room in which they work adversely affects their ergonomics or hinders their job performance. In addition to providing a healing space for patients, hospital patient rooms need to serve as functional workplaces for the people who provide clinical care, to clean, or to maintain room functions. Therefore, from a design perspective, it is important to understand the needs of all the users of hospital patient rooms with regard to room design. One hundred forty-seven people, representing 23 different occupational stakeholder groups, participated in either focus groups or interviews in which they were asked to identify room design issues that affect the performance of their work tasks. Key issues shared across multiple stakeholder groups included an inability to have eye contact with the patient when entering the room, inadequate space around the bed for the equipment used by stakeholders, the physical demands experienced as stakeholders move furnishings to accomplish their activities or access equipment, and a lack of available horizontal surfaces. Unique issues were also identified for a number of stakeholder groups. There are a number of issues that should be addressed in the next generation of hospital patient rooms, or when refurbishing existing facilities, so that all occupational stakeholder groups can work effectively, efficiently, and without undue physical stress. © The Author(s) 2015.

The "Occupational Earcheck" (OEC) is a Dutch online self-screening speech-in-noise test developed for the detection of occupational high-frequency hearing loss (HFHL). This study evaluates an optimised version of the test and determines the most appropriate masking noise. The original OEC was improved by homogenisation of the speech material, and shortening the test. A laboratory-based cross-sectional study was performed in which the optimised OEC in five alternative masking noise conditions was evaluated. The study was conducted on 18 normal-hearing (NH) adults, and 15 middle-aged listeners with HFHL. The OEC in a low-pass (LP) filtered stationary background noise (test version LP 3: with a cut-off frequency of 1.6 kHz, and a noise floor of -12 dB) was the most accurate version tested. The test showed a reasonable sensitivity (93%), and specificity (94%) and test reliability (intra-class correlation coefficient: 0.84, mean within-subject standard deviation: 1.5 dB SNR, slope of psychometric function: 13.1%/dB SNR). The improved OEC, with homogenous word material in a LP filtered noise, appears to be suitable for the discrimination between younger NH listeners and older listeners with HFHL. The appropriateness of the OEC for screening purposes in an occupational setting will be studied further.

Cheryl E. Peters

2018-06-01

Full Text Available Background: Selecting priority occupational carcinogens is important for cancer prevention efforts; however, standardized selection methods are not available. The objective of this paper was to describe the methods used by CAREX Canada in 2015 to establish priorities for preventing occupational cancer, with a focus on exposure estimation and descriptive profiles. Methods: Four criteria were used in an expert assessment process to guide carcinogen prioritization: (1 the likelihood of presence and/or use in Canadian workplaces; (2 toxicity of the substance (strength of evidence for carcinogenicity and other health effects; (3 feasibility of producing a carcinogen profile and/or an occupational estimate; and (4 special interest from the public/scientific community. Carcinogens were ranked as high, medium or low priority based on specific conditions regarding these criteria, and stakeholder input was incorporated. Priorities were set separately for the creation of new carcinogen profiles and for new occupational exposure estimates. Results: Overall, 246 agents were reviewed for inclusion in the occupational priorities list. For carcinogen profile generation, 103 were prioritized (11 high, 33 medium, and 59 low priority, and 36 carcinogens were deemed priorities for occupational exposure estimation (13 high, 17 medium, and 6 low priority. Conclusion: Prioritizing and ranking occupational carcinogens is required for a variety of purposes, including research, resource allocation at different jurisdictional levels, calculations of occupational cancer burden, and planning of CAREX-type projects in different countries. This paper outlines how this process was achieved in Canada; this may provide a model for other countries and jurisdictions as a part of occupational cancer prevention efforts.

The purpose of this study was to gain a comprehensive understanding of the facilitators of and barriers to learning within occupational therapy fieldwork education from the perspective of both Canadian and American students. A qualitative study using an online open survey format was conducted to gather data from 29 occupational therapy students regarding their fieldwork experiences. An inductive grounded theory approach to content analysis was used. Individual, environmental, educational, and institutional facilitators of and barriers to learning within occupational therapy fieldwork education were identified. This study's findings suggest that learning within fieldwork education is a highly individual and dynamic process that is influenced by numerous factors. The new information generated by this study has the potential to positively affect the future design and implementation of fieldwork education.

Early markers of airways inflammation and occupational asthma: Rationale, study design and follow-up rates among bakery, pastry and hairdressing apprentices

Directory of Open Access Journals (Sweden)

Hannhart Bernard

2009-04-01

Full Text Available Abstract Background Occupational asthma is a common type of asthma caused by a specific agent in the workplace. The basic alteration of occupational asthma is airways inflammation. Although most patients with occupational asthma are mature adults, there is evidence that airways inflammation starts soon after inception of exposure, including during apprenticeship. Airways hyper responsiveness to methacholine is a valid surrogate marker of airways inflammation, which has proved useful in occupational epidemiology. But it is time-consuming, requires active subject's cooperation and is not readily feasible. Other non-invasive and potentially more useful tests include the forced oscillation technique, measurement of fraction exhaled nitric oxide, and eosinophils count in nasal lavage fluid. Methods and design This study aims to investigate early development of airways inflammation and asthma-like symptoms in apprentice bakers, pastry-makers and hairdressers, three populations at risk of occupational asthma whose work-related exposures involve agents of different nature. The objectives are to (i examine the performance of the non-invasive tests cited above in detecting early airways inflammation that might eventually develop into occupational asthma; and (ii evaluate whether, and how, constitutional (e.g. atopy and behavioural (e.g. smoking risk factors for occupational asthma modulate the effects of allergenic and/or irritative substances involved in these occupations. This paper presents the study rationale and detailed protocol. Discussion Among 441 volunteers included at the first visit, 354 attended the fourth one. Drop outs were investigated and showed unrelated to the study outcome. Sample size and follow-up participation rates suggest that the data collected in this study will allow it to meet its objectives.

Indoor air quality in 24 California residences designed as high-performance homes

Today’s high performance green homes are reaching previously unheard of levels of airtightness and are using new materials, technologies and strategies, whose impacts on Indoor Air Quality (IAQ) cannot be fully anticipated from prior studies. This research study used pollutant measurements, home inspections, diagnostic testing and occupant surveys to assess IAQ in 24 new or deeply retrofitted homes designed to be high performance green buildings in California. Although the mechanically vented homes were six times as airtight as non-mechanically ventilated homes (medians of 1.1 and 6.1 ACH₅₀, n=11 and n=8, respectively), their use of mechanical ventilation systems and possibly window operation meant their median air exchange rates were almost the same (0.30 versus 0.32 hr^-1, n=8 and n=8, respectively). Pollutant levels were also similar in vented and unvented homes. In addition, these similarities were achieved despite numerous observed faults in complex mechanical ventilation systems. More rigorous commissioning is still recommended. Cooking exhaust systems were used inconsistently and several suffered from design flaws. Failure to follow best practices led to IAQ problems in some cases. Ambient nitrogen dioxide standards were exceeded or nearly so in four homes that either used gas ranges with standing pilots, or in Passive House-style homes that used gas cooking burners without venting range hoods. Homes without active particle filtration had particle count concentrations approximately double those in homes with enhanced filtration. The majority of homes reported using low-emitting materials; consistent with this, formaldehyde levels were approximately half those in conventional, new CA homes built before 2008. Emissions of ultrafine particles (with diameters <100 nm) were dramatically lower on induction electric cooktops, compared with either gas or resistance electric models. These results indicate that high performance homes can achieve

To analyze gender inequalities in employment and working conditions, the work-life balance, and work-related health problems in a sample of the employed population in Spain in 2007, taking into account social class and the economic sector. Gender inequalities were analyzed by applying 25 indicators to the 11,054 workers interviewed for the VI edition of the National Working Conditions Survey. Multivariate logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CI), stratifying by occupational social class and economic sector. More women than men worked without a contract (OR=1.83; 95% CI: 1.51-2.21) and under high-effort/low-reward conditions (1.14:1.05-1.25). Women also experienced more sexual harassment (2.85:1.75-4.62), discrimination (1.60:1.26-2.03) and musculoskeletal pain (1.38:1.19-1.59). More men than women carried out shift work (0.86:0.79-0.94), with high noise levels (0.34:0.30-0.40), and high physical demands (0.58:0.54-0.63). Men also suffered more injuries due to occupational accidents (0.67:0.59-0.76). Women white-collar-workers were more likely than their male counterparts to have a temporary contract (1.34:1.09-1.63), be exposed to psychosocial hazards and discrimination (2.47:1.49-4.09) and have occupational diseases (1.91:1.28-2.83). Gender inequalities were higher in the industry sector. There are substantial gender inequalities in employment, working conditions, and work-related health problems in Spain. These gender inequalities are influenced by social class and the economic sector, and should be considered in the design of public policies in occupational health. Copyright © 2011 SESPAS.

Bonde, J P; Giwercman, A; Ernst, E

1996-01-01

Malfunction of the male reproductive system might be a sensitive marker of environmental hazards, the effects of which may extend beyond reproductive function. The testis is more vulnerable to heat and ionising radiation than any other organ of the body and several xenobiotics are known to disrupt spermatogenesis after low level exposure. Studies of environmental impact on human health are often most informative and accurate when carried out in the workplace where exposures can be high and easy to document. Semen analysis provides readily obtainable information on testicular function. The main advantages in comparison with functional measures such as fertility rates and time taken to conceive are the possibilities to examine men independently of marriage and pregnancy, to find changes of fecundity with different exposures within the same person and to detect adverse effects when no alteration of fertility is yet taking place. In the implementation of an occupational sperm study considerable attention must be paid to logistic issues. A mobile laboratory unit for initial semen preparation and processing may in some situations increase worker compliance and the quality of sperm cell motility. The cross sectional design which has been used in almost all male reproductive studies so far has several severe limitations including selection bias because of differential participation, difficulties in defining a suitable reference group, and lack of information about the time dimension of the cause-effect relation. The longitudinal design deals adequately with most of these constraints. Semen samples are collected before, during, and possibly after exposure to the risk factor of interest and causal inferences are based upon change of semen variables within a man over time rather than upon differences between men. The logistics of the longitudinal study may benefit from pre-employment health examinations to enrol newly hired workers and require fewer participants to obtain

Although lay beliefs commonly relate high blood pressure to psychological stress exposure, research findings are conflicting. This study examined the association between current perceived stress and high blood pressure and explored the potential impact of occupational status on this association. Resting blood pressure was measured in 122,816 adults (84,994 men), aged ≥30 years (mean age ± standard deviation: 46.8±9.9 years), without history of cardiovascular and renal disease and not on either psychotropic or antihypertensive drugs. High blood pressure was defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg. Perceived stress in the past month was measured with the 4-item perceived stress scale. A total of 33,154 participants (27.0%) had high blood pressure (151±14/90±9 mmHg). After adjustment for all variables except occupational status, perceived stress was associated with high blood pressure (odds ratio for a 5-point increase: 1.06, 95% confidence interval: [1.03–1.09]). This association was no longer significant after additional adjustment for occupational status (odds ratio: 1.01 [0.99–1.04]). There was a significant interaction (phigh blood pressure among individuals of high occupational status (odds ratio: 0.91, [0.87–0.96]) but positively associated among those of low status (odds ratio: 1.10, [1.03–1.17]) or unemployed (odds ratio: 1.13, [1.03–1.24]). Sensitivity analyses yielded similar results. The association between current perceived stress and blood pressure depends upon occupational status. This interaction may account for previous conflicting results and warrants further studies to explore its underlying mechanisms. PMID:23319539

Occupational exposure to trichloroethylene (TCE) has been linked to adverse health outcomes including non-Hodgkin's lymphoma and kidney and liver cancer; however, TCE's mode of action for development of these diseases in humans is not well understood. Non-targeted metabolomics analysis of plasma obtained from 80 TCE-exposed workers [full shift exposure range of 0.4 to 230 parts-per-million of air (ppm a )] and 95 matched controls were completed by ultra-high resolution mass spectrometry. Biological response to TCE exposure was determined using a metabolome-wide association study (MWAS) framework, with metabolic changes and plasma TCE metabolites evaluated by dose-response and pathway enrichment. Biological perturbations were then linked to immunological, renal and exposure molecular markers measured in the same population. Metabolic features associated with TCE exposure included known TCE metabolites, unidentifiable chlorinated compounds and endogenous metabolites. Exposure resulted in a systemic response in endogenous metabolism, including disruption in purine catabolism and decreases in sulphur amino acid and bile acid biosynthesis pathways. Metabolite associations with TCE exposure included uric acid (β = 0.13, P-value = 3.6 × 10 -5 ), glutamine (β = 0.08, P-value = 0.0013), cystine (β = 0.75, P-value = 0.0022), methylthioadenosine (β = -1.6, P-value = 0.0043), taurine (β = -2.4, P-value = 0.0011) and chenodeoxycholic acid (β = -1.3, P-value = 0.0039), which are consistent with known toxic effects of TCE, including immunosuppression, hepatotoxicity and nephrotoxicity. Correlation with additional exposure markers and physiological endpoints supported known disease associations. High-resolution metabolomics correlates measured occupational exposure to internal dose and metabolic response, providing insight into molecular mechanisms of exposure-related disease aetiology. © The Author 2016; all rights

Definition and denomination of occupations in libraries

Directory of Open Access Journals (Sweden)

Jelka Gazvoda

1998-01-01

Full Text Available In the first part of the article, the author presents the modern definition of occupation as defined in the ISCO-88 standard, and consecutively in the Slovenian Standard Classification of Occupations; occupations in the field of library and information science are then placed in a wider frame of information occupations which are present in ali spheres of activities. The following part of the article is focused on information occupations in libraries, especially on their contents definitions and denominations.Based on the analysis of job descriptions in three Slovenian libraries (National and University Library, University Library of Maribor and Central Technical Library,the author came to the following conclusion: the existent practice in libraries shows that the contents and denominations of occupations in library and information jobs are defined too loosely. In most cases, the contents of occupation is defined by the contents of the job, while for its denomination the required educational title of the employee is often used. Therefore, the author proposes the establishment of a work force which would define the contents and design denominations to library and information occupations according to the principles contained in the Standard Classification of Occupations.

Control of occupational radiation exposures in TVA nuclear power plants - design and operating philosophy

International Nuclear Information System (INIS)

Belvin, E.A.; Lyon, M.; Beasley, E.G. Jr.; Zobel, W.; Stone, G.F.

1976-01-01

TVA has some 21,000 MWe of nuclear generation in various phases of design, construction, or operation. When Browns Ferry was designed in the late 1960's, there were no guidelines available regarding implant radiation control features, so TVA relied on good engineering and health physics judgement in developing its design and operating criteria for radiation protection. After two years of operation at Browns Ferry, the authors experience shows that their design criteria were in most cases adequate or more than adequate. However, several areas present continuing problems relative to radiation and contamination control. In view of the recent NRC ALARA guidelines, they have instituted a program to ensure that the ALARA concept is made an integral part of their design and operating plans. Administrative documents were issued giving management support to the ALARA concept. A 4-member management audit team consisting of representatives from their design, operating, and radiation protection groups was established to review the effectiveness of radiation protection design features and operating activities on a plant-by-plant basis. Reports and recommendations from these audits are sent to top-level management staff. Their goal is to maintain an audit-appraisal system consisting of in-plant awareness of radiation and contamination conditions, assessment of trends in occupational radiation exposures, and feedback to their designers regarding problems encountered during operation and maintenance activities

The Energy Saving Potential of Occupancy-Based Lighting Control Strategies in Open-Plan Offices: The Influence of Occupancy Patterns

Directory of Open Access Journals (Sweden)

Christel de Bakker

2017-12-01

Full Text Available Occupancy-based lighting control strategies have been proven to be effective in diminishing offices’ energy consumption. These strategies have typically worked by controlling lighting at the room level but, recently, lighting systems have begun to be equipped with sensors on a more fine-grained level, enabling lighting control at the desk level. For some office cases, however, the savings gained using this strategy may not outweigh the costs and design efforts compared to room control. This is because, in some offices, individual occupancy patterns are similar, hence the difference in savings between desk and room control would be minimal. This study examined the influence of occupancy pattern variance within an office space on the relative energy savings of control strategies with different control zone sizes. We applied stochastic modeling to estimate the occupancy patterns, as this method can account for uncertainty. To validate our model, simulation results were compared to earlier studies and real measurements, which demonstrated that our simulations provided realistic occupancy patterns. Next, office cases varying in both job-function type distribution and office policy were investigated on energy savings potential to determine the influence of occupancy pattern variance. The relative energy savings potential of the different control strategies differed minimally for the test cases, suggesting that variations in individual occupancy patterns negligibly influence energy savings. In all cases, lighting control at the desk level showed a significantly higher energy savings potential than strategies with lower control zone granularity, suggesting that it is useful to implement occupancy-based lighting at the desk level in all office cases. This strategy should, thus, receive more attention from both researchers and lighting designers.

The purpose of this study is to determine the relationship between occupational exposures and hearing among elderly Latino Americans. A descriptive, correlational design used for this secondary analysis with the data from the Sacramento Area Latino Study of Aging (SALSA). A total of 547 older adults were included. A majority of participants (58%) reported occupational exposures to loud noise and/or ototoxic chemicals. About 65% and over 90% showed hearing loss at low and high frequencies, respectively. Participants with occupational exposure to loud noise and/or ototoxic chemicals were, significantly, two times more likely to have hearing loss at high frequencies compared to those without exposure (OR = 2.29; 95% CI: 1.17 = 4.51, p = .016), after controlling for other risk factors of hearing loss such as age, gender, household income, current smoking, and diabetes. However, lifelong occupational exposure was not significantly associated with hearing loss at low frequencies (OR = 1.43; 95% CI: 0.94 = 2.18, p = .094). Lifelong occupational exposure to loud noise and/or ototoxic chemicals was significantly associated with hearing loss among elderly Latino Americans. Healthy work life through protection from harmful auditory effects of occupational exposures to noise and chemicals will have a positive impact on better hearing in later life.

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.

Nursing home employees experience high physical and psychosocial workloads, resulting in poor health outcomes. An occupational health/health promotion program, designed to facilitate employee participation, was initiated in three nursing homes. The aim of the current study was to evaluate facilitators and barriers of the program after 3-year implementation. Focus groups with employees and in-depth interviews with top and middle managers were conducted. The Social Ecological Model was used to organize the evaluation. Facilitators and barriers were reported from both managers’ and employees’ perspectives, and were categorized as intrapersonal, interpersonal, institutional, and corporate level. Management support, financial resources, and release time for participation were identified as the three most important factors. Supports from multiple levels including both human and environment, and managers and employees, are important for a successful participatory occupational health/health promotion program.

The purposes of this study were to investigate the prevalence of and risk factors for low back pain (LBP) in teachers and to evaluate the association of individual and occupational characteristics with the prevalence of LBP. In this cross-sectional study, 586 asymptomatic teachers were randomly selected from 22 primary and high schools in Semnan city of Iran. Data on the personal, occupational characteristics, pain intensity, and functional disability as well as the prevalence and risk factors of LBP were collected using different questionnaires. Point, last month, last 6 months, annual, and lifetime prevalence rates of LBP were 21.8%, 26.3%, 29.6%, 31.1%, and 36.5%, respectively. The highest prevalence was obtained for the high school teachers. The prevalence of LBP was significantly associated with age, body mass index, job satisfaction, and length of employment (P teachers appears to be high. High school teachers were more likely to experience LBP than primary school teachers. Factors such as age, body mass index, length of employment, job satisfaction, and work-related activities were significant factors associated with LBP in this teacher population.

Recent studies indicate that physically demanding work is a risk factor for heart disease among men, especially those with low or moderate physical activity during leisure time. Among women, present evidence is inconclusive. The design was a prospective cohort study. This investigation in the Danish Nurse Cohort Study included 12,093 female nurses aged 45-64 years, who answered a self-report questionnaire on physical activity at work and during leisure time, known risk factors for ischaemic heart disease (IHD) and occupational factors at baseline in 1993. Information on the 15-year incidence of IHD was obtained by individual linkage in the National Register of Hospital Discharges to 2008. During follow-up 580 participants were hospitalised with IHD. A significant interaction between occupational and leisure time physical activity was found with the lowest risk of IHD among nurses with the combination of moderate physical activity at work and vigorous physical activity during leisure time. Compared to this group high physical activity at work was associated with a higher risk of IHD at all levels of physical activity during leisure time increasing from hazard ratio 1.75 (95% confidence interval (CI) 1.10-2.80) among nurses with vigorous physical activity during leisure time to 2.65 (95% CI 1.44-4.88) among nurses being sedentary during leisure time. This study among Danish nurses suggests that high physical activity at work is a risk factor for IHD among women. Vigorous physical activity during leisure time lowered but did not completely counteract the adverse effect of occupational physical activity on risk of IHD. © The European Society of Cardiology 2014.

2018-02-01

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.

Towards servitization in the management of occupational safety

Directory of Open Access Journals (Sweden)

Jasmina Berbegal

2014-04-01

Full Text Available Purpose: This article aims to examine the relationship between occupational accidents and the type of occupational safety resources that the company implements. Design/methodology/approach: Using a sample of 4750 firms gathered from the National Survey of Safety Management and Health Enterprises (ENGE for 2009, we first carried out a descriptive analysis of the data, and second we run an empirical analysis based on logistic and Tobit regressions. Findings and Originality/value: The results allow us to identify which companies and what kind of preventive activities are usually outsourced to an external firm specialized at providing occupational safety services. Second, the empirical analysis shows that outsourcing part of occupational safety activities also helps reduce the index of workplace accidents. Research limitations/implications: The present case focuses on Spanish companies and for a particular period (years 2007 and 2008. Because each country has specific regulations regarding the implementation of occupational safety services, the conclusions cannot be directly extrapolated to other countries. Practical implications: The results obtained are hoped to assist companies in choosing those prevention services that best suits their needs. Furthermore, this study is expected to contribute to the current debate on the design of prevention policies by public authorities, encouraging the outsourcing of occupational safety services as a way to take advantage of their expertise and reduce the number of accidents. Originality/value: Most of the academic literature on occupational safety has ignored the study of the impact that prevention services have on the firm’s performance, in terms of occupational accidents. This article contributes to filling this gap by demonstrating that the servitization trend is also impacting in the field of occupational safety.

Occupational medicine changes with the times

The activities of the occupation health physicians also at the Karlsruhe Nuclear Research Center have experienced a change in focus over the past few decades, the causes of which are in the working environment and in work processes. The causes and conditions of diseases at work must be recognized and preventive measures instituted, but there is also need to design the working environment in terms of occupational physiology and industrial hygiene so as to meet human requirements. This includes the use of sociological and psychological concepts and methods in modern occupational medicine. This recognition necessitates the appropriate efforts to be made both in scientific research and in daily medical practive. Modern working life is determined by the joint action of physical and psychological impacts, with more and more importance attaching to psychosensoric impacts. As a result of this development, occupational health physicians spend increasingly more time and effort in medical consulting and on problems in occupational medicine, social medicine, and ergonomics.

We evaluated the effects of occupation-based intervention on poststroke upper-extremity (UE) motor recovery, neuroplastic change, and occupational performance in 1 research participant. A 55-yr-old man with chronic stroke and moderately impaired UE motor function participated in 15 sessions of occupation-based intervention in a hospital setting designed to simulate a home environment. We tested behavioral motor function (Fugl-Meyer Assessment, Stroke Impact Scale, Canadian Occupational Performance Measure) and neuroplasticity (transcranial magnetic stimulation [TMS]) at baseline and at completion of intervention. We collected descriptive data on occupational participation throughout the study. All behavioral outcomes indicated clinically relevant improvement. TMS revealed bihemispheric corticomotor reorganization. Descriptive data revealed enhanced occupational performance. Occupation-based intervention delivered in a hospital-based, homelike environment can lead to poststroke neuroplastic change, increased functional use of the affected UE, and improved occupational performance.

Converting a congested high-occupancy vehicle (HOV) lane into a high-occupancy toll (HOT) lane is a viable option for improving travel time reliability for carpools and buses that use the managed lane. However, the emission impacts of HOV-to-HOT conversions are not well understood. The lack of emission impact quantification for HOT conversions creates a policy challenge for agencies making transportation funding choices. The goal of this paper is to evaluate the case study of before-and-after changes in vehicle emissions for the Atlanta, Georgia, I-85 HOV/HOT lane conversion project, implemented in October 2011. The analyses employed the Motor Vehicle Emission Simulator (MOVES) for project-level analysis with monitored changes in vehicle activity data collected by Georgia Tech researchers for the Georgia Department of Transportation (GDOT). During the quarterly field data collection from 2010 to 2012, more than 1.5 million license plates were observed and matched to vehicle class and age information using the vehicle registration database. The study also utilized the 20-sec, lane-specific traffic operations data from the Georgia NaviGAtor intelligent transportation system, as well as a direct feed of HOT lane usage data from the State Road and Tollway Authority (SRTA) managed lane system. As such, the analyses in this paper simultaneously assessed the impacts associated with changes in traffic volumes, on-road operating conditions, and fleet composition before and after the conversion. Both greenhouse gases and criteria pollutants were examined. A straight before-after analysis showed about 5% decrease in air pollutants and carbon dioxide (CO 2 ). However, when the before-after calendar year of analysis was held constant (to account for the effect of 1 yr of fleet turnover), mass emissions at the analysis site during peak hours increased by as much as 17%, with little change in CO 2 . Further investigation revealed that a large percentage decrease in criteria

We investigated the association between six occupational exposures (ie, pesticides, solvents, metals, diesel motor emissions (DME), extremely low frequency magnetic fields (ELF-MF) and electric shocks) and Parkinson's disease (PD) mortality in a large population-based prospective cohort study. The Netherlands Cohort Study on diet and cancer enrolled 58,279 men and 62,573 women aged 55-69 years in 1986. Participants were followed up for cause-specific mortality over 17.3 years, until December 2003, resulting in 402 male and 207 female PD deaths. Following a case-cohort design, a subcohort of 5,000 participants was randomly sampled from the complete cohort. Information on occupational history and potential confounders was collected at baseline. Job-exposure matrices were applied to assign occupational exposures. Associations with PD mortality were evaluated using Cox regression. Among men, elevated HRs were observed for exposure to pesticides (eg, ever high exposed, HR 1.27, 95% CI 0.86 to 1.88) and ever high exposed to ELF-MF (HR 1.54, 95% CI 1.00 to 2.36). No association with exposure duration or trend in cumulative exposure was observed for any of the occupational exposures. Results among women were unstable due to small numbers of high-exposed women. Associations with PD mortality were observed for occupational exposure to pesticides and ELF-MF. However, the weight given to these findings is limited by the absence of a monotonic trend with either duration or cumulative exposure. No associations were found between PD mortality and occupational exposure to solvents, metals, DME or electric shocks. Published by the BMJ Publishing Group Limited.

Role Performance and Role Valuation Among Occupational Therapy Students in Norway

Directory of Open Access Journals (Sweden)

Tore Bonsaksen

2016-01-01

Full Text Available Background: The Model of Human Occupation describes roles as providing the person with a framework around which to organize daily occupations. Role performance and role valuation in young adults may be related to gender, but there are few research studies to date to support this view. Methods: This study is a cross-sectional design using a sample of 87 occupational therapy students in Norway. We used the Role Checklist to assess the students’ performance and valuation of roles, and a variety of statistical procedures were employed in the analysis. Results: Compared to the female participants, males performed roles in the community, social, and civic life area of participation more frequently. Otherwise, male and female participants were largely equal in current role performance. For most roles, we found associations between role performance and high valuation of the respective roles. Discussion: Gender appears to be a factor of relevance for our understanding of role performance. This study suggests that occupational therapists should consider the societal as well as the personal aspects of roles. In addition, occupational therapy interventions could aim toward improving congruence between the roles clients perform and the value these roles have for them

Occupational injuries remain an important unresolved issue in many of the developing and developed countries. We aimed to outline the causes, characteristics, measures and impact of occupational injuries among different ethnicities. We reviewed the literatures using PUBMED, MEDLINE, Google Scholar and EMBASE search engine using words: "Occupational injuries" and "workplace" between 1984 and 2014. Incidence of fatal occupational injuries decreased over time in many countries. However, it increased in the migrant, foreign born and ethnic minority workers in certain high risk industries. Disproportionate representations of those groups in different industries resulted in wide range of fatality rates. Overrepresentation of migrant workers, foreign born and ethnic minorities in high risk and unskilled occupations warrants effective safety training programs and enforcement of laws to assure safe workplaces. The burden of occupational injuries at the individual and community levels urges the development and implementation of effective preventive programs.

Occupational and industrial exposures have been implicated in the etiology of leukemia, yet uncertainty remains regarding potential high risk occupations. We examined the associations between self-reported occupations and hobbies and acute leukemia risk using data from 811 cases and 637 controls participating in a case-control study in the U.S. and Canada. We found that several occupations may increase the risk of acute leukemia, particularly occupations related to petroleum products, rubber, nuclear energy, munitions, plastics, and electronics manufacturing. Differences were noted according to histological type. Other occupations and hobbies were not clearly associated with risk.

Due to recent reforms, the demands on the people working in community-oriented health care service are increasing. The individual providers need professional knowledge and skills to perform their tasks quickly and safely. The individuals are also confronted with new tasks and situations of which they lack experience. At the same time, the resources for education and development are decreasing. The aim of this paper is to describe the implementation of a prototype computer network service to support occupational therapists in their daily work. A customized Quality Function Deployment (QFD) model, including participatory design elements, was used for: (a) identification of the occupational therapists' needs; and (b) for the transformation of these needs to prioritized design attributes. The main purpose of the prototype was to improve the visualization of the design attributes that were found to support the occupational therapists. An additional purpose was to be able to evaluate the design attributes and further improve them. The specific aim of this article is to describe the initial prototype with respect both to the tools and the information content.

Spirituality is recognized as an essential and integral component of a holistic approach in occupational therapy practice. However, little is known about occupational therapy students' perceptions regarding spirituality in learning context. This study used qualitative exploratory, descriptive design to explore the occupational therapy students' perceptions about spirituality in training. Using purposive sampling, four semi-structured interviews were conducted with two students, a lecturer and an occupational therapist. In addition, two focus groups were conducted with students in order to collect data. Data collected were audio-taped; transcribed and thematic analysis was used to identify themes. The analysis resulted in emergence of four themes: "Unique to every individual," "Spirituality in occupational therapy," "To be or not to be taught," and "The Real world." Participants perceived spirituality as an individually experienced. The study contributes to the body of knowledge base of occupational therapy education regarding spirituality. However, there is a need for guidelines to integrate spirituality in occupational therapy training.

The aim of this study was to investigate whether a four-month occupational based health-promoting programme for older persons living in community dwellings could maintain/improve their general health and well-being. Further, the aim was to explore whether the programme facilitated the older persons' occupational adaptation. The study had a quasi-experimental design, with a non-equivalent control group combined with semi-structured interviews. The intervention group comprised 22 participants, and the control group 18. Outcomes were measured using the Short Form 36, Life Satisfaction Index-Z and Meaningful Activity Participation Assessment. Content analysis, based on concepts from the Model of Occupational Adaptation, was used to analyse the interviews. The intervention group showed statistically significant improvements in general health variables such as vitality and mental health, and positive trends for psychological well-being. There were no statistically significant differences between the intervention group and the control group, but the groups were not fully matched. The qualitative analysis based on Occupational Adaptation pointed out social aspects as a compliment to the overall results. Participating in meaningful, challenging activities in different environments stimulates the occupational adaptation process; this is something occupational therapists could use to empower older persons to find their optimal occupational lives.

Carlos Duarte; Kevin Van Den Wymelenberg; Craig Rieger

2013-06-01

Energy simulation programs like DOE-2 and EnergyPlus are tools that have been proven to aid with energy calculations to predict energy use in buildings. Some inputs to energy simulation models are relatively easy to find, including building size, orientation, construction materials, and HVAC system size and type. Others vary with time (e.g. weather and occupancy) and some can be a challenge to estimate in order to create an accurate simulation. In this paper, the analysis of occupancy sensor data for a large commercial, multi-tenant office building is presented. It details occupancy diversity factors for private offices and summarizes the same for open offices, hallways, conference rooms, break rooms, and restrooms in order to better inform energy simulation parameters. Long-term data were collected allowing results to be presented to show variations of occupancy diversity factors in private offices for time of day, day of the week, holidays, and month of the year. The diversity factors presented differ as much as 46% from those currently published in ASHRAE 90.1 2004 energy cost method guidelines, a document referenced by energy modelers regarding occupancy diversity factors for simulations. This may result in misleading simulation results and may introduce inefficiencies in the final equipment and systems design.

Background Gender specific analysis of the occupational disease of the lumbar spine caused by carrying, lifting, or extreme trunk flexion in Germany (OD No.2108) with the aim to identify areas of focus for prevention and research with a prevention index (PI). Methods Data from the German Statutory Accident Insurance stratified by gender are shown. Results From 2002 until 2009 there were 2,877 confirmed cases of an OD No. 2108 (40.1% male and 59.1% female). The PI indicated the highest prevention need for female nursing/midwifery associate professionals and male building frame and related trades workers. Patient transfer and working in extremely bent posture were the most frequent exposures. Conclusions The identified occupations with high need for prevention among men come from nearly all major occupational groups whereas women cluster in occupational groups from the health and care sectors.

Professional burnout has been described as a gradual erosion of a person and may be one of the possible consequences of chronic occupational stress. Although occupational stress has been surveyed among dentists in Hong Kong, no study has been published about burnout in the profession. This study aimed to evaluate burnout among Hong Kong dentists and its association with occupational stress. We surveyed a random sample of 1086 registered dentists in Hong Kong, which formed 50% of the local profession. They were mailed an anonymous questionnaire about burnout and occupational stress in 2015. The questionnaire assessed occupational stress, coping strategies, effects of stress, level of burnout, and socio-demographic characteristics of the respondents. Occupational stress assessment concerned 33 stressors in five groups: patient-related, time-related, income-related, job-related, and staff-/technically related. Level of burnout was assessed by the Maslach Burnout Inventory-Human Services Survey (22 items) with three scores: emotional exhaustion, depersonalisation, and personal accomplishment. Completed questionnaires were received from 301 dentists (response rate, 28.3%), of whom 25.4% had a high level of emotional exhaustion, 17.2% had a high level of depersonalisation, and 39.0% had a low level of personal accomplishment. Only 7.0% of respondents, however, had a high level of overall burnout (high emotional exhaustion, high depersonalisation, and low personal accomplishment). A high level of overall burnout was significantly associated with a higher mean score for job-related stressors and lack of postgraduate qualifications (Poccupational stressors experienced by dentists in Hong Kong. In spite of this, a low proportion of dentists have a high level of overall burnout. There was a positive association between occupational stress and level of burnout.

Can occupancy-abundance models be used to monitor wolf abundance?

Directory of Open Access Journals (Sweden)

M Cecilia Latham

Full Text Available Estimating the abundance of wild carnivores is of foremost importance for conservation and management. However, given their elusive habits, direct observations of these animals are difficult to obtain, so abundance is more commonly estimated from sign surveys or radio-marked individuals. These methods can be costly and difficult, particularly in large areas with heavy forest cover. As an alternative, recent research has suggested that wolf abundance can be estimated from occupancy-abundance curves derived from "virtual" surveys of simulated wolf track networks. Although potentially more cost-effective, the utility of this approach hinges on its robustness to violations of its assumptions. We assessed the sensitivity of the occupancy-abundance approach to four assumptions: variation in wolf movement rates, changes in pack cohesion, presence of lone wolves, and size of survey units. Our simulations showed that occupancy rates and wolf pack abundances were biased high if track surveys were conducted when wolves made long compared to short movements, wolf packs were moving as multiple hunting units as opposed to a cohesive pack, and lone wolves were moving throughout the surveyed landscape. We also found that larger survey units (400 and 576 km2 were more robust to changes in these factors than smaller survey units (36 and 144 km2. However, occupancy rates derived from large survey units rapidly reached an asymptote at 100% occupancy, suggesting that these large units are inappropriate for areas with moderate to high wolf densities (>15 wolves/1,000 km2. Virtually-derived occupancy-abundance relationships can be a useful method for monitoring wolves and other elusive wildlife if applied within certain constraints, in particular biological knowledge of the surveyed species needs to be incorporated into the design of the occupancy surveys. Further, we suggest that the applicability of this method could be extended by directly incorporating some of its

Occupational radiation exposure in Germany: many monitored persons = high exposure?

International Nuclear Information System (INIS)

Nitschke, J.

1996-01-01

Natural radiation affects the entire population in Germany, and most of Germany's inhabitants are exposed to medical radiation in their lifetime. Occupational radiation exposure, however, is a kind of exposure affecting only a limited and well-defined group of the population, and this radiation exposure has been recorded and monitored as precisely as technically possible ever since the radiation protection laws made occupational radiation exposure monitoring a mandatory obligation. Official personal dosimetry applying passive dosemeters in fact does not offer direct protection against the effects of ionizing radiation, as dosemeter read-out and dose calculation is a post-exposure process. But it nevertheless is a rewarding monitoring duty under radiation protection law, as is shown by the radiation exposure statistics accumulated over decades: in spite of the number of monitored persons having been increasing over the years, the total exposure did not, due to the corresponding improvements in occupational radiation protection.

Occupational lung diseases in Australia.

Science.gov (United States)

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.

2003-01-01

The purpose of this study was to examine the perceptions of special education directors on the current role of occupational therapy in high school transition programs for adolescent students with disabilities. Additionally, barriers to providing occupational therapy services and perceptions about new occupational therapy services were examined. A mailed questionnaire was administered to all special education directors in a rural state in the United States. One hundred and four (57.5%) responses were received. Descriptive statistics were generated with an emphasis on percentages to examine current occupational therapy services in high school transition programs and barriers to service delivery. In this study, occupational therapists provided less than one fifth of transition services in high schools for students with disabilities. They provided more assistive technology consults (30.3%), task or environmental modification (25.8%), and Individualized Education Plan (IEP) and Individualized Transition Plan (ITP) planning (20%) than other providers. Barriers to occupational therapy use included funding, lack of inter-agency planning, and lack of parent participation. About 35% of special education directors suggested that additional occupational therapy services were needed for adolescents with cognitive disabilities and for job performance and related work skills programming. Occupational therapists in this study provided ancillary services to high school students with disabilities with greater emphasis on technology, task or environmental modification, and IEP or ITP planning, as perceived by special evaluation directors.

Previous work has established that health care staff, in particular emergency department (ED) personnel, experience significant occupational stress but the underlying stressors have not been well quantified. Such data inform interventions that can reduce cases of occupational mental illness, burnout, staff turnover and early retirement associated with cumulative stress. To develop, implement and evaluate a questionnaire examining the origins of occupational stress in the ED. A questionnaire co-designed by an occupational health practitioner and ED management administered to nursing, medical and support staff in the ED of a large English teaching hospital in 2015. The questionnaire assessed participants' demographic characteristics and perceptions of stress across three dimensions (demand-control-support, effort-reward and organizational justice). Work-related stressors in ED staff were compared with those of an unmatched control group from the acute ear, nose and throat (ENT) and neurology directorate. A total of 104 (59%) ED staff returned questionnaires compared to 72 staff (67%) from the acute ENT/neurology directorate. The ED respondents indicated lower levels of job autonomy, management support and involvement in organizational change, but not work demand. High levels of effort-reward imbalance and organizational injustice were reported by both groups. Our findings suggest that internal ED interventions to improve workers' job control, increase support from management and involvement in organizational change may reduce work stress. The high levels of effort-reward imbalance and organizational injustice reported by both groups may indicate that wider interventions beyond the ED are also needed to address these issues. © The Author 2016.

Current and new challenges in occupational lung diseases

Directory of Open Access Journals (Sweden)

Sara De Matteis

2017-11-01

Full Text Available Occupational lung diseases are an important public health issue and are avoidable through preventive interventions in the workplace. Up-to-date knowledge about changes in exposure to occupational hazards as a result of technological and industrial developments is essential to the design and implementation of efficient and effective workplace preventive measures. New occupational agents with unknown respiratory health effects are constantly introduced to the market and require periodic health surveillance among exposed workers to detect early signs of adverse respiratory effects. In addition, the ageing workforce, many of whom have pre-existing respiratory conditions, poses new challenges in terms of the diagnosis and management of occupational lung diseases. Primary preventive interventions aimed to reduce exposure levels in the workplace remain pivotal for elimination of the occupational lung disease burden. To achieve this goal there is still a clear need for setting standard occupational exposure limits based on transparent evidence-based methodology, in particular for carcinogens and sensitising agents that expose large working populations to risk. The present overview, focused on the occupational lung disease burden in Europe, proposes directions for all parties involved in the prevention of occupational lung disease, from researchers and occupational and respiratory health professionals to workers and employers.

Common occupational classification system - revision 3

Energy Technology Data Exchange (ETDEWEB)

Stahlman, E.J.; Lewis, R.E.

1996-05-01

Workforce planning has become an increasing concern within the DOE community as the Office of Environmental Restoration and Waste Management (ER/WM or EM) seeks to consolidate and refocus its activities and the Office of Defense Programs (DP) closes production sites. Attempts to manage the growth and skills mix of the EM workforce while retaining the critical skills of the DP workforce have been difficult due to the lack of a consistent set of occupational titles and definitions across the complex. Two reasons for this difficulty may be cited. First, classification systems commonly used in industry often fail to cover in sufficient depth the unique demands of DOE`s nuclear energy and research community. Second, the government practice of contracting the operation of government facilities to the private sector has introduced numerous contractor-specific classification schemes to the DOE complex. As a result, sites/contractors report their workforce needs using unique classification systems. It becomes difficult, therefore, to roll these data up to the national level necessary to support strategic planning and analysis. The Common Occupational Classification System (COCS) is designed to overcome these workforce planning barriers. The COCS is based on earlier workforce planning activities and the input of technical, workforce planning, and human resource managers from across the DOE complex. It provides a set of mutually-exclusive occupation titles and definitions that cover the broad range of activities present in the DOE complex. The COCS is not a required record-keeping or data management guide. Neither is it intended to replace contractor/DOE-specific classification systems. Instead, the system provides a consistent, high- level, functional structure of occupations to which contractors can crosswalk (map) their job titles.

Indoor environmental conditions (thermal, noise, light, and indoor air quality) may affect workers' comfort, and consequently their health and well-being, as well as their productivity. This study aimed to assess the relations between perceived indoor environment and occupants' comfort, and to examine the modifying effects of both personal and building characteristics. Within the framework of the European project OFFICAIR, a questionnaire survey was administered to 7441 workers in 167 "modern" office buildings in eight European countries (Finland, France, Greece, Hungary, Italy, The Netherlands, Portugal, and Spain). Occupants assessed indoor environmental quality (IEQ) using both crude IEQ items (satisfaction with thermal comfort, noise, light, and indoor air quality), and detailed items related to indoor environmental parameters (e.g., too hot/cold temperature, humid/dry air, noise inside/outside, natural/artificial light, odor) of their office environment. Ordinal logistic regression analyses were performed to assess the relations between perceived IEQ and occupants' comfort. The highest association with occupants' overall comfort was found for "noise", followed by "air quality", "light" and "thermal" satisfaction. Analysis of detailed parameters revealed that "noise inside the buildings" was highly associated with occupants' overall comfort. "Layout of the offices" was the next parameter highly associated with overall comfort. The relations between IEQ and comfort differed by personal characteristics (gender, age, and the Effort Reward Imbalance index), and building characteristics (office type and building's location). Workplace design should take into account both occupant and the building characteristics in order to provide healthier and more comfortable conditions to their occupants.

Occupational balance in health professionals in Sweden.

Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational balance in three different samples of health professionals in Sweden. A further aim was to investigate whether occupational therapists (OTs) rate their occupational balance differently from other health professionals. Four hundred and eighty-two health professionals, employees in public dentistry, mental health care and OTs, aged 21-70 years participated. The participants' occupational balance was measured using the occupational balance questionnaire (OBQ). The ratings of occupational balance were similar to earlier studies and did not differ significantly between the samples. The OTs' occupational balance was also similar to that of the other health professionals. The similarities in occupational balance indicate the same difficulties in attaining it. The result highlights the possibility that working people face similar difficulties in achieving occupational balance. Further research is warranted about how to attain it.

Occupation and its relationship with health and wellbeing: the threshold concept for occupational therapy.

Science.gov (United States)

Fortune, Tracy; Kennedy-Jones, Mary

2014-10-01

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.

Full Text Available Abstract Background This research examines the specific contribution of occupation and work organization conditions to alcohol use and misuse. It is based on a social-action model that takes into account agent personality, structures of daily life, and macro social structures. Methods Data come from a representative sample of 10,155 workers in Quebec, Canada. Multinomial regression models corrected for sample design effect have been used to predict low-risk and high-risk drinking compared to non-drinkers. The contribution of occupation and work organization conditions (skill used, decision authority, physical and psychological demands, hours worked, irregular work schedule, harassment, unionization, job insecurity, performance pay, prestige have been adjusted for family situation, social network outside the workplace, and individual characteristics. Results Compared to non-qualified blue-collars, both low-risk and high-risk drinking are associated with qualified blue-collars, semi-qualified white-collars, and middle managers; high-risk drinking is associated with upper managers. For constraints-resources related to work organization conditions, only workplace harassment is an important determinant of both low-risk and high-risk drinking, but it is modestly moderated by occupation. Family situation, social support outside work, and personal characteristics of individuals are also associated with alcohol use and misuse. Non-work factors mediated/suppressed the role of occupation and work organization conditions. Conclusion Occupation and workplace harassment are important factors associated with alcohol use and misuse. The results support the theoretical model conceptualizing alcohol use and misuse as being the product of stress caused by constraints and resources brought to bear simultaneously by agent personality, structures of daily life, and macro social structures. Occupational alcohol researchers must expand their theoretical perspectives to

2015-01-01

As an early response to the Fukushima Daiichi NPP accident, the Information System on Occupational Exposure (ISOE) Bureau decided to focus on the following issues as an initial response of the joint program after having direct communications with the Japanese official participants in April 2011: - Management of high radiation area worker doses: It has been decided to make available the experience and information from the Chernobyl accident in terms of how emergency worker / responder doses were legally and practically managed, - Personal protective equipment for highly-contaminated areas: It was agreed to collect information about the types of personnel protective equipment and other equipment (e.g. air bottles, respirators, air-hoods or plastic suits, etc.), as well as high-radiation area worker dosimetry use (e.g. type, number and placement of dosimetry) for different types of emergency and high-radiation work situations. Detailed information was collected on dose criteria which are used for emergency workers /responders and their basis, dose management criteria for high dose/dose rate areas, protective equipment which is recommended for emergency workers / responders, recommended individual monitoring procedures, and any special requirement for assessment from the ISOE participating nuclear utilities and regulatory authorities and made available for Japanese utilities. With this positive response of the ISOE official participants and interest in the situation in Fukushima, the Expert Group on Occupational Radiation Protection in Severe Accident Management (EG-SAM) was established by the ISOE Management Board in May 2011. The overall objective of the EG-SAM is to contribute to occupational exposure management (providing a view on management of high radiation area worker doses) within the Fukushima plant boundary with the ISOE participants and to develop a state-of-the-art ISOE report on best radiation protection management practices for proper radiation

To investigate the association of Parkinson disease (PD) with education and occupations using a case-control study design. The authors used the medical records-linkage system of the Rochester Epidemiology Project to identify all subjects who developed PD in Olmsted County, MN, from 1976 through 1995. Each incident case was matched by age (+/-1 year) and sex to a general population control. The authors collected information about education and occupations using two independent sources of data: a review of the complete medical records in the system and a telephone interview. Occupations were coded using the 1980 Standard Occupational Classification. Subjects with 9 or more years of education were at increased risk of PD (OR = 2.0; 95% CI = 1.1 to 3.6; p = 0.02), and there was a trend of increasing risk with increasing education (test for linear trend, p = 0.02; medical records data). Physicians were at significantly increased risk of PD using both sources of occupational data. By contrast, four occupational groups showed a significantly decreased risk of PD using one source of data: construction and extractive workers (e.g., miners, oil well drillers), production workers (e.g., machine operators, fabricators), metal workers, and engineers. These associations with increased or decreased risk did not change noticeably after adjustment for education. Subjects with higher education and physicians have an increased risk of Parkinson disease (PD), while subjects with some occupations presumed to involve high physical activity have a decreased risk of PD.

Occupational exposure in the National Health Service - the North Western Region

Following the introduction of the Ionising Radiations Regulations 1985, a review of the level of occupational exposure in the NHS in the North Western Region was undertaken to ascertain whether any person needed to be designated as a classified person and to demonstrate compliance with the regulations concerning non-classified persons working in controlled areas. The initial survey of the 1986 dose data indicated that the level of whole-body occupational dose received by the vast majority of NHS employees was, as expected, extremely low. However, the survey also identified a group of staff involved in brachytherapy who did receive relatively high occupational doses. Operational procedures were reviewed and further dose reduction methods implemented; these, together with the continuing introduction of remotely controlled afterloading techniques, has led to a significant reduction in both individual and collective doses in this group and since 1988 no individual has received a whole-body dose exceeding 10 mSv.

The article examines which subjectively evaluated indoor environmental parameters and building features mostly affect occupants' satisfaction in mainly US office buildings. The study analyzed data from a web-based survey administered to 52,980 occupants in 351 office buildings over 10 years by the Center for the Built Environment. The survey uses 7-point ordered scale questions pertaining to satisfaction with indoor environmental parameters, workspace, and building features. The average building occupant was satisfied with his/her workspace and building. Proportional odds ordinal logistic regression shows that satisfaction with all 15 parameters listed in the survey contributed significantly to overall workspace satisfaction. The most important parameters were satisfaction with amount of space (odds ratio OR 1.57, 95% CI: 1.55-1.59), noise level (OR 1.27, 95% CI: 1.25-1.29), and visual privacy (OR 1.26, 95% CI: 1.24-1.28). Satisfaction with amount of space was ranked to be most important for workspace satisfaction, regardless of age group (below 30, 31-50 or over 50 years old), gender, type of office (single or shared offices, or cubicles), distance of workspace from a window (within 4.6 m or further), or satisfaction level with workspace (satisfied or dissatisfied). Satisfaction with amount of space was not related to the gross amount of space available per person. To maximize workspace satisfaction, designer should invest in aspects that increase satisfaction with amount of space and storage, noise level, and visual privacy. Office workers will be most satisfied with their workspace and building when located close to a window in a private office. This may affect job satisfaction, work performance, and personal and company productivity. © 2011 John Wiley & Sons A/S.

Protection of indoor air quality and human health can be achieved via ventilation, which has becomes one of the most important tasks for sustainable buildings. This approach also requires highly efficient and energy saving methods for modern building ventilations consisting of a set of parameters of the complex indoor system. Therefore, the advancement in understanding the characteristics of various ventilation methods is highly necessary. This study presents one novel air supply model for the complex occupant micro-environment demand control ventilations, to analyze the efficiency of various ventilation types. This model is established primarily according to the momentum and mass conservations, and goal of occupant micro-environment demand, which is a complex system with the characteristics of diversity and dynamic variation. As for different occupant densities, characteristics of outdoor air supply for controlling gaseous pollutant and three basic features of outdoor airflow supply reaching occupant micro-environment were obtained. This research shows that for various types of occupant density and storey height, the rising and descending rates of the demand outdoor airflow in mixing ventilation are higher than those under displacement ventilation conditions. In addition, since the structure is better designed and sewage flow is more efficient, the mixing ventilation also requires a much higher peak demand outdoor airflow than its counterpart. The increase of storey height will lead to a decline of pollutants in the breathing zone and the demand outdoor airflow. Fluctuations of air flow diffusion caused by the change of occupant density in architectural space, will lead to variations of outdoor airflow reaching occupant micro-environment. Accordingly, it would lead to the different peak values of demand outdoor airflow, and the difference becomes even significant if the occupant density increases. The variations of the air supply and fraction of air reaching the

Employee’s occupational stress and safety performance are highly related, which has been generally recognized by the researchers. We did this research to understand the status of the stress for construction workers, and explore the influence factors of pressure source with characteristics of construction industry. Based on the results of previous studies, we designed questionnaire to collect the influence factors on occupational stressors. The study selected workers from certain construction units at the grass-roots level as sample source. According to the results of the questionnaire, we redesigned the interview outline, and did the semi-structured interviews on workers randomly selected. Finally, we developed a scale which combined the characteristics of construction projects in China. Using SPSS software for factor analysis, reliability analysis, and descriptive statistical analysis, the results show that there are six factors affecting the workers’ occupational stress, including The Work Itself, Family-Work, Career Development, Organization Style, Interpersonal Relationship and Role Management Style. The work itself is the main sources of occupational stress. The results can be used by the construction company to provide guidance for workers to control and manage occupational stress.

The effect of occupational meaningfulness on occupational commitment

Directory of Open Access Journals (Sweden)

2014-11-01

Full Text Available Existing research lacks a scholarly consensus on how to define and validly measure ‘meaningful work’ (e.g., Rosso, Dekas & Wrzesniewski, 2010. The following correlational study highlights the value of investigating meaningfulness in the context of occupational commitment. The study hypothesizes that occupational commitment is positively correlated with occupational meaningfulness, where meaningfulness is defined as the extent to which people’s occupations contribute to personal meaning in life. One-hundred and fifty-six full-time office based UK workers completed an online questionnaire including 18 questions measuring levels of occupational commitment (Meyer, Allen & Smith, 1993, in addition to six novel items measuring occupational meaningfulness. The results supported the hypothesis and also showed that the affective sub-type of occupational commitment had the highest correlation with occupational meaningfulness. Such results exhibit the importance of finding meaning at work, as well as the relevance of this to one’s level of commitment to his or her job. This paper argues that individuals should consider OM before choosing to take a specific role, whereas organizations ought to consider the OM of their potential candidates before recruiting them into a role. Possible directions for future research directions are also discussed.

The evidence regarding the effects of occupational exposure to low levels of ionizing radiation on reproductive health is limited. However, exposure to high doses of ionizing radiation is associated with increased risk of adverse reproductive outcomes. The resulting uncertainty about the effects of occupational exposures has caused concern among some workers, therefore, we have designed a study to examine this question among Canadian medical radiation technologists. A short mailed questionnaire will be sent to all CAMRT members to obtain information about reproductive history, and a sample of respondents will receive a second questionnaire requesting information about other important exposures. Occupational dose records will be retrieved from the National Dose Registry. Using this information, relative risks for each outcome will be calculated for different radiation dose levels. This article provides a brief review of the literature on ionizing radiation exposure and reproductive outcomes, and an outline of the proposed study

Latino adults between ages 50 and 60 yr are at high risk for developing chronic conditions that can lead to early disability. We conducted a qualitative pilot study with 11 Latinos in this demographic group to develop a foundational schema for the design of health promotion programs that could be implemented by occupational therapy practitioners in primary care settings for this population. One-on-one interviews addressing routines and activities, health management, and health care utilization were conducted, audiotaped, and transcribed. Results of a content analysis of the qualitative data revealed the following six domains of most concern: Weight Management; Disease Management; Mental Health and Well-Being; Personal Finances; Family, Friends, and Community; and Stress Management. A typology of perceived health-actualizing strategies was derived for each domain. This schema can be used by occupational therapy practitioners to inform the development of health-promotion lifestyle interventions designed specifically for late-middle-aged Latinos.

There is increasing evidence that obesity and overweight may be related, in part, to adverse work conditions. In particular, the risk of obesity may increase in high-demand, low-control work environments, and for those who work long hours. In addition, obesity may modify the risk for vibration-induced injury and certain occupational musculoskeletal disorders. We hypothesized that obesity may also be a co-risk factor for the development of occupational asthma and cardiovascular disease that and it may modify the worker's response to occupational stress, immune response to chemical exposures, and risk of disease from occupational neurotoxins. We developed 5 conceptual models of the interrelationship of work, obesity, and occupational safety and health and highlighted the ethical, legal, and social issues related to fuller consideration of obesity's role in occupational health and safety.

Acosta, Martha Soledad Vela; Sechrest, Lee; Chen, Mei-Kuang

2009-01-01

Bilingual and bicultural occupational health and safety interventions for Hispanic farmworkers are extremely rare and, because of language barriers and cultural differences, issues important to their health and safety on the job remain unaddressed. We designed, conducted, and assessed the first bilingual occupational health and safety education program for farmworkers attending High School Equivalency Programs (HEPs). We took an interdisciplinary participatory approach by integrating educators and researchers with a community advisory board to guide development, evaluation, and implementation of Work Safely-Trabaje con Cuidado Curriculum (Curriculum), a bilingual occupational health and safety curriculum. We created a quasi-experimental design using mixed-method evaluation (quantitative and qualitative elements) via pre- and posttest comparisons, follow-up surveys, and focus groups assessing the Curriculum effect on knowledge, safety risk perception (SRP), and safety behavior. Focus groups and follow-up surveys reflected success and acceptance of the Curriculum among participating farmworkers under the study's logic model. Completion of the Curriculum resulted in statistically significant improvements in the combined score of knowledge and SRP at the posttest (p = 0.001) and follow-up survey (p = 0.02) in the intervention group. After completing this study, the Curriculum was permanently adopted by the two high school equivalency sites involved. The participatory approach resulted in integration of community and applied research partnership. The potential to expand use of this Curriculum by other HEP sites can further assess effectiveness and external validity among underserved minority groups.

Occupancy-counter-based control system. Final report

Energy Technology Data Exchange (ETDEWEB)

Schultz, G.; Hoagland, L. C.; Bowman, J. K.

1979-07-01

Excessive mechanical ventilation of commercial and institutional buildings can result in significant waste of energy required for space heating and cooling. Ventilation rates are typically set to satisfy building design occupancy levels, in accordance with local codes, even though the building may seldom or never experience design occupancy. A method of eliminating this waste to utilize an occupancy-based ventilation control system wherein a counting device records people entering and leaving the building, to maintain a continuous record of people inventory, and to regulate mechanical ventilation control dampers to supply only that amount of ventilation air required for current occupancy levels is described. A device of this type was installed and tested in a department store in Framingham, Massachusetts and fully instrumented and operated over a 14 month period. Test results on energy usage were correlated with weather severity in order to determine the savings resulting from use of the control system. This system provided a savings of 33% in gas usage during the winter period and a savings of 23% in electricity usage during the summer period. These savings would return the installed cost of the control system in about 1 1/2 years. Projections of the performance of this system in other climatic regions (Chicago, Los Angeles, Kansas City, Miami, Minneapolis) are also presented illustrating payback periods ranging from 1/3 year in Miami to 2 2/3 years in Los Angeles. Complete details of the occupancy based ventilation control system, the test site instrumentation and data gathering procedure, the test results and their interpretation are given. (MCW)

This study's purpose was to describe the occupational needs and goals of women residing in a domestic violence shelter and their self-perceived changes in satisfaction and occupational performance. Using a retrospective design, data from 68 occupational therapy evaluations from two domestic violence shelter settings were examined. Data were analyzed by coding problem areas and occupational goals and calculating frequencies for these variables. Where data were available, we also analyzed changes in pre- and postscores for self-perceived satisfaction and occupational performance (n = 25). The most common problem areas were leisure, education, work, child rearing, and health management. The most common goals were in the areas of education, work, health management, child rearing, and home management. Retrospective pre- and postchange scores in performance and satisfaction for 25 women were statistically significant. Findings provide direction for, and highlight the importance of occupational therapy services within domestic violence shelters as women regain their life skills.

2010-01-01

Mild positive affect has been shown in the psychological literature to improve cognitive skills of creative problem-solving and systematic thinking. Individual preferred music listening offers opportunity for improved positive affect. The purpose of this study was to examine the effect of preferred music listening on state-mood and cognitive performance in a high-cognitive demand occupation. Twenty-four professional computer information systems developers (CISD) from a North American IT company participated in a 3-week study with a music/no music/music weekly design. During the music weeks, participants listened to their preferred music "when they wanted, as they wanted." Self-reports of State Positive Affect, State Negative Affect, and Cognitive Performance were measured throughout the 3 weeks. Results indicate a statistically significant improvement in both state-mood and cognitive performance scores. "High-cognitive demand" is a relative term given that challenges presented to individuals may occur on a cognitive continuum from need for focus and selective attention to systematic analysis and creative problem-solving. The findings and recommendations have important implications for music therapists in their knowledge of the effect of music on emotion and cognition, and, as well, have important implications for music therapy consultation to organizations.

Occupant feedback based model predictive control for thermal comfort and energy optimization: A chamber experimental evaluation

Chen, Xiao; Wang, Qian; Srebric, Jelena

2016-01-01

Highlights: • This study evaluates an occupant-feedback driven Model Predictive Controller (MPC). • The MPC adjusts indoor temperature based on a dynamic thermal sensation (DTS) model. • A chamber model for predicting chamber air temperature is developed and validated. • Experiments show that MPC using DTS performs better than using Predicted Mean Vote. - Abstract: In current centralized building climate control, occupants do not have much opportunity to intervene the automated control system. This study explores the benefit of using thermal comfort feedback from occupants in the model predictive control (MPC) design based on a novel dynamic thermal sensation (DTS) model. This DTS model based MPC was evaluated in chamber experiments. A hierarchical structure for thermal control was adopted in the chamber experiments. At the high level, an MPC controller calculates the optimal supply air temperature of the chamber heating, ventilation, and air conditioning (HVAC) system, using the feedback of occupants’ votes on thermal sensation. At the low level, the actual supply air temperature is controlled by the chiller/heater using a PI control to achieve the optimal set point. This DTS-based MPC was also compared to an MPC designed based on the Predicted Mean Vote (PMV) model for thermal sensation. The experiment results demonstrated that the DTS-based MPC using occupant feedback allows significant energy saving while maintaining occupant thermal comfort compared to the PMV-based MPC.

This study was a post-occupancy evaluation (POE) to examine the effectiveness of three specific design innovations in a mental healthcare facility. In addition to collecting data about the impact of these specific designs, the study provides a model for the broader implementation of POE approaches in the mental healthcare context. POEs in general healthcare settings have been shown to lead to better work environments and better outcomes for patients. Despite growing evidence of the value provided by POE studies, the industry has been somewhat slow to adopt their regular use, in part due to unfamiliarity with the POE process. This is particularly true in mental healthcare contexts, where POE studies remain virtually nonexistent. In-depth interviews and a widely distributed, anonymous survey were used to collect hospital staff perceptions and feedback regarding the impact of specific design features. The hospital staff were quite enthusiastic about two of the design innovations studied here (a new wayfinding strategy and the use of vibrant colors in specific areas of the facility). The third innovation, open-style communication centers, elicited more mixed evaluations. The results include extensive hypothesis testing about the effects of each innovation as well as narrative discussions of their pros and cons. The study generated new knowledge about three specific mental healthcare design innovations and provides a model for the practical implementation of a POE approach in mental healthcare contexts. The results are particularly relevant for designers who are considering innovative strategies in future mental healthcare facilities.

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.

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.

2015-07-01

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.

Galaxy halo occupation at high redshift

Bullock, James S.; Wechsler, Risa H.; Somerville, Rachel S.

2002-01-01

We discuss how current and future data on the clustering and number density of z~3 Lyman-break galaxies (LBGs) can be used to constrain their relationship to dark matter haloes. We explore a three-parameter model in which the number of LBGs per dark halo scales like a power law in the halo mass: N(M)=(M/M1)S for M>Mmin. Here, Mmin is the minimum mass halo that can host an LBG, M1 is a normalization parameter, associated with the mass above which haloes host more than one observed LBG, and S determines the strength of the mass-dependence. We show how these three parameters are constrained by three observable properties of LBGs: the number density, the large-scale bias and the fraction of objects in close pairs. Given these three quantities, the three unknown model parameters may be estimated analytically, allowing a full exploration of parameter space. As an example, we assume a ΛCDM cosmology and consider the observed properties of a recent sample of spectroscopically confirmed LBGs. We find that the favoured range for our model parameters is Mmin~=(0.4-8)×1010h- 1Msolar, M1~=(6-10)×1012h- 1Msolar, and 0.9acceptable if the allowed range of bg is permitted to span all recent observational estimates. We also discuss how the observed clustering of LBGs as a function of luminosity can be used to constrain halo occupation, although because of current observational uncertainties we are unable to reach any strong conclusions. Our methods and results can be used to constrain more realistic models that aim to derive the occupation function N(M) from first principles, and offer insight into how basic physical properties affect the observed properties of LBGs.

Green building standards are significantly impacting modern construction practices. The resulting structures are more energy efficient, but their impact on occupant health has not been widely studied. To investigate a range of indoor environment and ergonomic issues in green buildings. Retrospective post-occupancy evaluation survey of 319 occupants in two Leadership in Energy and Environmental Design (LEED) certified buildings and one conventional building on a Canadian University campus. Results show that working in the LEED buildings was a generally positive experience for their health, performance, and satisfaction. However, the LEED buildings did not always receive the highest ratings for environmental conditions or for health and productivity. Respondents indicated a range of concerns with thermal conditions, office lighting, noise and their overall workstation designs and these were not always better in the green buildings. These results highlight the need for better integration of ergonomic design into green buildings and into the LEED rating system, and these implications are discussed.

Improving employees' perception of organizational climate, and coaching them to remain steadfast when managing occupational risks associated with their job, might have an important effect on their psychosocial wellbeing and occupational health. This study examined the effects of a rational emotive occupational health therapy intervention program on the perceptions of organizational climate and occupational risk management practices. The participants were 77 electronics technology employees in the south-east of Nigeria. The study used a pretest-posttest control group design. The rational emotive occupational health therapy intervention program significantly improved perceptions of the organizational climate for the people in the treatment group compared to those in the waitlist control group at post-intervention and follow-up assessments. Occupational risk management practices of the employees in the treatment group were also significantly better than those in the waitlist control group at the same 2 assessments. Corporate application of a rational emotive behavior therapy as an occupational health therapy intervention program is essential for improving the perceptions of organizational climate and promoting the adoption of feasible occupational risk management strategies in the workplace.

POST OCCUPANCY EVALUATION OF ENERGY-EFFICIENT BUILDINGS IN TROPICAL CLIMATES – MALAYSIA

Full Text Available There exists a well-known gap between occupants and building’s energy-efficient designs. A comprehensive building performance diagnostic technique, Post Occupancy Evaluation (POE may surpass the current evaluation method by reducing the gap between occupants and building’s energy-efficient design. Due to these reasons, the aim of this research is to identify the problems with respect to energy-efficient design which affect occupants’ comfort. This research focuses on the application of energy-efficient design in office building and was conducted on energy-efficient buildings in Malaysia. A building performance survey framework, Energy-efficient Building Environmental Quality Questionnaire (EBEQ2, was  used to identify the problems affecting occupants’ comfort and buildings’ Indoor Environmental Quality (IEQ. The result was analyzed using Statistical Package for Social Science (SPSS. The research outcome shows that majority of occupants are not satisfied  with the thermal comfort and lighting condition of  the buildings. Building certified with sustainable building rating tools does not guarantee better IEQ performance. Thus  continuous research is needed to ensure energy-efficient building concept is applied effectively in each type of building.

Smart building temperature control using occupant feedback

structure necessary for truthful comfort feedback from the occupants. Finally, we present an end-to-end framework designed for enabling occupant feedback collection and incorporating the feedback data towards energy efficient operation of a building. We have designed a mobile application that occupants can use on their smart phones to provide their thermal preference feedback. When relaying the occupant feedback to the central server the mobile application also uses indoor localization techniques to tie the occupant preference to their current thermal zone. Texas Instruments sensortags are used for real time zonal temperature readings. The mobile application relays the occupant preference along with the location to a central server that also hosts our learning algorithm to learn the environment and using occupant feedback calculates the optimal temperature set point. The entire process is triggered upon change of occupancy, environmental conditions, and or occupant preference. The learning algorithm is scheduled to run at regular intervals to respond dynamically to environmental and occupancy changes. We describe results from experimental studies in two different settings: a single family residential home setting and in a university based laboratory space setting. (Abstract shortened by UMI.).

Eriksen, P.

1987-01-01

A large population of workers are exposed to ultraviolet radiation in various occupational environments which often necessitates protection. Since ultraviolet radiation may create other environmental problems an occupational hazard- and protection evaluation can be complicated. Threshold Limit Values adopted by the American Conference of Governmental Industrial Hygienists (ACGIH) on ultraviolet radiation are used in most countries as guidelines for risk assessment and control measures. This review addresses the levels of ultraviolet radiation met in occupational environments, its measurement and evaluation, and discusses different protection methods. Ultraviolet lasers are beginning to find their way into industrial processes but are still limited in number and they will not be covered here. Emphasis is on broad band incoherent radiation in high risk environments such as welding, and on the evaluation of protective eyewear, see-through curtains and plastics. Other occupational risks associated with the emission of ultraviolet radiation are discussed

The greatest threat to human well-being in this century is climate change and related global issues. We examined the effectiveness of the Modified Instrumentalism in Occupational Therapy model as a framework for facilitating occupational behaviour change to address climate change and related issues. Eleven individuals participated in this mixed-methods single-subject-design study. Data were gathered using the Modified Assessment and Intervention Instrument for Instrumentalism in Occupational Therapy and Daily Occupational Inventories. Quantitative data were analyzed using two- and three-standard deviation band methods. Qualitative data were analyzed using heuristic phenomenological procedures. Occupational performance changed for five participants. Participants' feelings shifted from frustration and helplessness to empowerment and a desire for action. They felt empowered to find occupation-based solutions to the global issues. Occupation-based interventions that increase personal awareness of the connection between occupational performance and global issues could empower people to be agents for action to ameliorate the issues.

Objective: The purpose of this study was to identify the needs for professional development of the OHN in the occupational health setting. Method: An explorative, descriptive, contextual generic and qualitative research method was used in this study. The purposive sampling method was used as the OHNs surveyed described their personal need for professional development in the occupational health setting. Data was collected by means of semi-structured individual interviews. Eight interviews were done by an interviewer who held a doctoral degree in community health nursing and a qualification in occupational health and was affiliated with a private occupational health institution at the time of the study. The interviews were conducted during August 2012. Results: The OHNs reported that professional development needs have to be identified by the OHNs. Short courses need to be designed by training institutions and should be attended by the OHNs to improve their operational functioning on a day-to-day basis in the occupational health setting. The OHNs experienced that their role and function in the workplace were not valued by their managers. The results of this study revealed four major themes, namely constraints hindering the OHN in developing professionally, positive aspects identified by the OHNs regarding the need for professional development, professional development needs of the OHN and suggestions of how to meet the OHNs' professional development needs. Conclusion: There is a need for OHNs to identify their professional development needs and recommendations were made to meet these needs.

Full Text Available Abstract Background Even effective interventions for people with dementia and their caregivers require specific implementation efforts. A pilot study showed that the highly effective community occupational therapy in dementia (COTiD program was not implemented optimally due to various barriers. To decrease these barriers and make implementation of the program more effective a combined implementation (CI strategy was developed. In our study we will compare the effectiveness of this CI strategy with the usual educational (ED strategy. Methods In this cluster randomized, single-blinded, controlled trial, each cluster consists of at least two occupational therapists, a manager, and a physician working at Dutch healthcare organizations that deliver community occupational therapy. Forty-five clusters, stratified by healthcare setting (nursing home, hospital, mental health service, have been allocated randomly to either the intervention group (CI strategy or the control group (ED strategy. The study population consists of the professionals included in each cluster and community-dwelling people with dementia and their caregivers. The primary outcome measures are the use of community OT, the adherence of OTs to the COTiD program, and the cost effectiveness of implementing the COTiD program in outpatient care. Secondary outcome measures are patient and caregiver outcomes and knowledge of managers, physicians and OTs about the COTiD program. Discussion Implementation research is fairly new in the field of occupational therapy, making this a unique study. This study does not only evaluate the effects of the CI-strategy on professionals, but also the effects of professionals' degree of implementation on client and caregiver outcomes.

Objective: To review the audiometry results of employees at the campus of the University of São Paulo, Bauru. Method: 40 audiometry results were analyzed between 2007 and 2008, whose ages comprised between 32 and 59 years, of both sexes and several professions: gardeners, maintenance technicians, drivers etc. The participants were divided into 2 groups: those with tonal thresholds within acceptable thresholds and those who presented auditory thresholds alterations, that is tonal thresholds below 25 dB (NA in any frequency (Administrative Rule no. 19 of the Ministry of Labor 1998. In addition to the Conventional Audiologic Evaluation (250Hz to 8.000Hz we also carried out High Frequencies Audiometry (9000Hz, 10000Hz, 11200Hz, 12500Hz, 14000Hz and 16000Hz. Results: According to the classification proposed by FIORINI (1994, 25.0% (N=10 they presented with NIHL suggestive audiometric configurations. The results of high frequencies Audiometry confirmed worse thresholds than those obtained in the conventional audiometry in the 2 groups evaluated. Conclusion: The use of high frequencies audiometry proved to be an important register as a hearing alteration early detection method.

A Building Energy Efficiency Optimization Method by Evaluating the Effective Thermal Zones Occupancy

Directory of Open Access Journals (Sweden)

Franco Cotana

2012-12-01

Full Text Available Building energy efficiency is strongly linked to the operations and control systems, together with the integrated performance of passive and active systems. In new high quality buildings in particular, where these two latter aspects have been already implemented at the design stage, users’ perspective, obtained through post-occupancy assessment, has to be considered to reduce whole energy requirement during service life. This research presents an innovative and low-cost methodology to reduce buildings’ energy requirements through post-occupancy assessment and optimization of energy operations using effective users’ attitudes and requirements as feedback. As a meaningful example, the proposed method is applied to a multipurpose building located in New York City, NY, USA, where real occupancy conditions are assessed. The effectiveness of the method is tested through dynamic simulations using a numerical model of the case study, calibrated through real monitoring data collected on the building. Results show that, for the chosen case study, the method provides optimized building energy operations which allow a reduction of primary energy requirements for HVAC, lighting, room-electricity, and auxiliary supply by about 21%. This paper shows that the proposed strategy represents an effective way to reduce buildings’ energy waste, in particular in those complex and high-efficiency buildings that are not performing as well as expected during the concept-design-commissioning stage, in particular due to the lack of feedback after the building handover.

2008-05-01

Full Text Available Abstract Background Major depressive disorder (MDD has major consequences for both patients and society, particularly in terms of needlessly long sick leave and reduced functioning. Although evidence-based treatments for MDD are available, they show disappointing results when implemented in daily practice. A focus on work is also lacking in the treatment of depressive disorder as well as communication of general practitioners (GPs and other health care professionals with occupational physicians (OPs. The OP may play a more important role in the recovery of patients with MDD. Purpose of the present study is to tackle these obstacles by applying a collaborative care model, which has proven to be effective in the USA, with a focus on return to work (RTW. From a societal perspective, the (costeffectiveness of this collaborative care treatment, as a way of transmural care, will be evaluated in depressed patients on sick leave in the occupational health setting. Methods/Design A randomised controlled trial in which the treatment of MDD in the occupational health setting will be evaluated in the Netherlands. A transmural collaborative care model, including Problem Solving Treatment (PST, a workplace intervention, antidepressant medication and manual guided self-help will be compared with care as usual (CAU. 126 Patients with MDD on sick leave between 4 and 12 weeks will be included in the study. Care in the intervention group will be provided by a multidisciplinary team of a trained OP-care manager and a consultant psychiatrist. The treatment is separated from the sickness certification. Data will be collected by means of questionnaires at baseline and at 3, 6, 9 and 12 months after baseline. Primary outcome measure is reduction of depressive symptoms, secondary outcome measure is time to RTW, tertiary outcome measure is the cost effectiveness. Discussion The high burden of MDD and the high level of sickness absence among people with MDD contribute to

Skin cancer is the most commonly diagnosed cancer type worldwide, and 80 % of skin cancers are basal cell carcinoma (BCC). The main risk factor for developing BCC is exposure to ultraviolet radiation (UVR), particularly high-dose exposure at a young age. Outdoor workers, particularly farmers, are at high risk of developing BCC. However, studies of BCC in this population are scant. To comprehensively evaluate all cases of BCC of the head and neck region treated during the years 2007-2013 at our hospital in Poland, and to compare the tumour characteristics in farmers to non-farmers. Retrospective analysis of 312 patients treated for head and neck BCC during the study period (2007-2013). Most patients (198 cases; 63 %) were males, with 114 females (37 %). Median age was 73 years (range 32-96 years). The most common tumour location was the nose and cheek (114 pts; 37 %) followed by the auricle (82 pts; 26 %), lips (54 pts; 18 %), scalp (26 pts; 8 %), and eye (36 pts; 12 %). The most common disease stage on presentation was stage T2 (104 pts, 33 %), followed by stage T1 (79 pts; 25 %), stage T3 (89 pts; 28 %), and stage T4 (40 pts; 14 %). By occupation, farmers accounted for 33 % of all patients (102 of 312 pts). The most common tumour localisations in the farmer subgroup were the nose and cheek (50 pts; 49 %; p farmer group were significantly younger than non-farmers (62 vs. 73 years; p Farmers were significantly more likely to present disease recurrence (27 vs. 12 % of cases; p farmers. It is therefore necessary to consider enhancing educational programmes and other preventative measures in this occupational group and to evaluate the effectiveness of such programmes.

Industrialized dairy production in the U.S. relies on an immigrant, primarily Latino/a, workforce to meet greater production demands. Given the high rates of injuries and illnesses on U.S. dairies, there is pressing need to develop culturally appropriate training to promote safe practices among immigrant, Latino/a dairy workers. To date, there have been few published research articles or guidelines specific to developing effective occupational safety and health (OSH) training for immigrant, Latino/a workers in the dairy industry. Literature relevant to safety training for immigrant workers in agriculture and other high-risk industries (e.g., construction) was examined to identify promising approaches. The aim of this paper is to provide a practical guide for researchers and practitioners involved in the design and implementation of effective OSH training programs for immigrant, Latino/a workers in the dairy industry. The search was restricted to peer-reviewed academic journals and guidelines published between 1980 and 2015 by universities or extension programs, written in English, and related to health and safety training among immigrant, Latino/a workers within agriculture and other high-risk industries. Relevant recommendations regarding effective training transfer were also included from literature in the field of industrial-organizational psychology. A total of 97 articles were identified, of which 65 met the inclusion criteria and made a unique and significant contribution. The review revealed a number of promising strategies for how to effectively tailor health and safety training for immigrant, Latino/a workers in the dairy industry grouped under five main themes: (1) understanding and involving workers; (2) training content and materials; (3) training methods; (4) maximizing worker engagement; and (5) program evaluation.

The study area is divided into spatially distinct sites where the detected presence or absence of the population is recorded, and this is repeated in time for multiple seasons. However, when occupied sites are detected with probability p Ecology 84, 2200-2207) developed a multiseason model for estimating seasonal site occupancy (ψt ) while accounting for unknown p. Their model performs well when observations are collected according to the robust design, where multiple sampling occasions occur during each season; the repeated sampling aids in the estimation p. However, their model does not perform as well when the robust design is lacking. In this paper, we propose an alternative likelihood model that yields improved seasonal estimates of p and Ψt in the absence of the robust design. We construct the marginal likelihood of the observed data by conditioning on, and summing out, the latent number of occupied sites during each season. A simulation study shows that in cases without the robust design, the proposed model estimates p with less bias than the MacKenzie et al. model and hence improves the estimates of Ψt . We apply both models to a data set consisting of repeated presence-absence observations of American robins (Turdus migratorius) with yearly survey periods. The two models are compared to a third estimator available when the repeated counts (from the same study) are considered, with the proposed model yielding estimates of Ψt closest to estimates from the point count model.

Purpose: The purpose of the study is to examine the relationship between external job mobility and occupational job mobility on earnings among engineers in Malaysia. Design/methodology/approach: Using curricular vitae data from a job agency, this paper tracks job mobility through job histories and examine how it affects earnings. Findings: Results obtained from regression analysis indicate that higher external job mobility will contribute to higher earnings, but occupational mobility will have adverse effect on earnings. Research limitations/implications: Limitation of the study is that the results are extrapolated from a self-report dataset. Practical implications: Nonetheless, the results give important implications to the Malaysian job market on how firm-specific skills and occupational specific skills are rewarded among engineers who actively seek for alternative employment online, and a guide to job applicants in career planning. Originality/value: The findings has also revealed important variables to be included in explaining high skill labor earnings in the context of Malaysian engineers, it serves as an important reference for future in modeling earnings.

Research indicates occupational injuries and diseases are not evenly distributed among workers. We investigated the distribution and characteristics of compensated occupational injuries and diseases requiring medical care in the Finnish farming population. The study population consisted of 93,564 Finnish farmers, spouses, and salaried family members who were covered by the mandatory workers' compensation insurance in 2002. This population had a total of 133,207 occupational injuries and 9,148 occupational diseases over a 26-year period (1982-2008). Clustering of claims was observed. Nearly half (47.1%) of the population had no compensated claims while 52.9% had at least one; 50.9% of farmers had one or more injuries and 8.1% had one or more diseases. Ten percent of the population had half of injury cases, and 3% of the population had half of occupational disease cases. Claims frequently involved work tasks related to animal husbandry and repair and maintenance of farm machinery. Injury and disease characteristics (work activity, cause, ICD-10 code) differed between individuals with high and low personal claim rate. Injuries and diseases of the musculoskeletal system had a tendency to reoccur among those with high claim rate. These outcomes were often related to strenuous working motions and postures in labor-intensive animal husbandry. Analyses of longitudinal insurance data contributes to better understanding of the long-term risk of occupational injury and disease among farmers. We suggest focusing on recurrent health outcomes and their causes among high risk populations could help design more effective interventions in agriculture and other industries.

Full Text Available Abstract Background A recent Dutch mono-centre randomised controlled trial has shown that occupational therapy improves daily functioning in dementia. The aim of this present study is to compare the effects of the Dutch community occupational therapy programme with a community occupational therapy consultation on daily functioning in older people with mild or moderate dementia and their primary caregivers in a German multi-centre context. Methods/Design A multi-centre single blind randomised controlled trial design is being used in seven health care centres (neurological, psychiatric and for older people in urban regions. Patients are 1:1 randomised to treatment or control group. Assessors are blind to group assignment and perform measurements on both groups at baseline, directly after intervention at 6 weeks and at 16, 26 and 52 weeks follow-up. A sample of 140 community dwelling older people (aged >65 years with mild or moderate dementia and their primary caregivers is planned. The experimental intervention consists of an evidence-based community occupational therapy programme including 10 sessions occupational therapy at home. The control intervention consists of one community occupational therapy consultation based on information material of the Alzheimer Society. Providers of both interventions are occupational therapists experienced in treatment of cognitively impaired older people and trained in both programmes. 'Community' indicates that occupational therapy intervention occurs in the person's own home. The primary outcome is patients' daily functioning assessed with the performance scale of the Interview for Deterioration in Daily Living Activities in Dementia and video tapes of daily activities rated by external raters blind to group assignment using the Perceive, Recall, Plan and Perform System of Task Analysis. Secondary outcomes are patients' and caregivers' quality of life, mood and satisfaction with treatment; the caregiver

Occupational risk for Legionella infection among dental healthcare workers: meta-analysis in occupational epidemiology.

Science.gov (United States)

Petti, Stefano; Vitali, Matteo

2017-07-13

The occupational risk for Legionella infection among dental healthcare workers (DHCWs) is conjectured because of the risk of routine inhalation of potentially contaminated aerosols produced by the dental instruments. Nevertheless, occupational epidemiology studies are contrasting. This meta-analysis assessed the level of scientific evidence regarding the relative occupational risk for Legionella infection among DHCWs. Literature search was performed without time and language restrictions, using broad data banks (PubMed, Scopus, Web of Science, GOOGLE Scholar) and generic keywords ('legionella' AND 'dent*'). Analytical cross-sectional studies comparing prevalence of high serum Legionella antibody levels in DHCWs and occupationally unexposed individuals were considered. The relative occupational risk was assessed through prevalence ratio (PR) with 95% CI. Between-study heterogeneity was assessed (Cochran's Q test) and was used to choose the meta-analytic method. Study quality (modified Newcastle-Ottawa Scale) and publication bias (Begg and Mazumdar's test, Egger and colleagues' test, trim and fill R 0 method) were assessed formally and considered for the sensitivity analysis. Sensitivity analysis to study inclusion, subgroup analyses (dental staff categories; publication year, before vs after 1998, ie, 5 years after the release by the Centers for Disease Control and Prevention of the infection control guidelines in dental healthcare setting) were performed. Seven studies were included (2232 DHCWs, 1172 occupationally unexposed individuals). No evidence of publication bias was detected. The pooled PR estimate was statistically non-significant at 95% level (1.7; 95% CI 0.8 to 3.2), study-quality adjustment did not change the PR considerably (PR, 1.5; 95% CI 0.5 to 4.1). PR was statistically significant before 1998 and no longer significant after 1998. Subgroup analysis according to DHCW categories was inconclusive. There is no scientific evidence that DHCWs are

Smart buildings are run by Cyber-Physical Systems (CPS), termed as Building Management Systems (BMS). Typical goals for the operation of BMS are increasing occupant comfort and decreasing buildings energy consumption. The central and critical figure, however, for achieving both goals are buildings......' occupants. In some BMS, occupants have a high level of interaction with the system, whereas in others this is limited to a large extent, barring occupants from even opening windows.

Larson, E A

2000-01-01

This article describes the relationship of mothers' orchestration of daily occupations, the specialized maternal work of parenting a child with a disability, and the mother's subjective well-being. Mothers' daily occupations and subjective well-being were studied using multiple in-depth interviews, participant observation of a day's round of occupations, and scales of well-being. Data were treated to a recursive analysis, which included theoretical notes generated during transcriptions that identified important themes and additional points of inquiry, line-by-line coding of transcripts, and theoretical sorting of codes and regrouping, recoding. To account for patterns in the data, a relational analysis was conducted that included the generation of metaphors. Emergent findings of this analysis identified the mothers' guiding occupational motif and eight processes of orchestration in their daily routines. The occupational motif, the embrace of paradox, directed the mother's orchestration of daily occupations. The orchestration processes included planning, organizing, balancing, anticipating, interpreting, forecasting, perspective shifting, and meaning making. Examples illustrate the maternally driven and child-sensitive nature of these processes. In their daily rounds, the mothers studied were attentive to the manner and method with which they interacted with their children to produce child-contingent occupations commensurate with their values of being a good mother. Using these orchestration processes, mothers made sense of their past, designed their present, and planned for their future within their daily occupational rounds for themselves and family members.

To allocate available resources as efficiently as possible, decision makers need information on the relative economic merits of occupational health and safety (OHS) interventions. Economic evaluations can provide this information by comparing the costs and consequences of alternatives. Nevertheless, only a few of the studies that consider the effectiveness of OHS interventions take the extra step of considering their resource implications. Moreover, the methodological quality of those that do is generally poor. Therefore, this study aims to help occupational health researchers conduct high-quality trial-based economic evaluations by discussing the theory and methodology that underlie them, and by providing recommendations for good practice regarding their design, analysis, and reporting. This study also helps consumers of this literature with understanding and critically appraising trial-based economic evaluations of OHS interventions.

Ali, T.H.; Khahro, S.H.; Memon, F.A.

2014-01-01

It has been observed that the construction industry is one of the notorious industry having higher rate of facilities and injuries. Resulting in higher financial losses and work hour losses, which are normally faced by this industry due to occupational accidents. Construction industry has the highest occupational accidents rate recorded throughout the world after agriculture industry. The construction work site is often a busy place having an incredibly high account of activities taking place, where everyone is moving in frenzy having particular task assigned. In such an environment, occupational accidents do occur. This paper gives information about different types of occupational accidents and their causes in the construction industry of Pakistan. A survey has been carried out to identify the types of occupational accidents often occur at construction site. The impact of each occupational accident has also been identified. The input from the different stakeholders involved on the work site was analyzed using RIW (Relative Importance Weight) method. The findings of this research show that fall from elevation, electrocution from building power and snake bite are the frequent occupational accidents occur within the work site where as fall from elevation, struck by, snake bite and electrocution from faulty tool are the occupational accident with high impact within the construction industry of Pakistan. The results also shows the final ranking of the accidents based on higher frequency and higher impact. Poor Management, Human Element and Poor Site Condition are found as the root causes leading to such occupational accidents. Hence, this paper identify that what type of occupational accidents occur at the work place in construction industry of pakistan, in order to develop the corrective actions which should be adequate enough to prevent the re-occurrence of such accidents at work site.

Role of radiology in occupational medicine

International Nuclear Information System (INIS)

Vehmas, T.

2004-01-01

This review discusses the contribution of radiology to occupational medicine as well as work-related problems in radiology dept.s. Research issues are emphasized. Radiology has been used especially when diagnosing occupational respiratory and locomotive system problems and solvent-induced encephalo- and hepatopathy. The aim of research in these areas is usually to characterize occupational diseases and to identify physico-chemical hazards in the work place by comparing between groups of workers and non-exposed controls. Radiological imaging allows an objective characterization of the disease, and it may clarify the pathogenesis of the process and provide a useful epidemiological tool. Advanced statistical methods are often needed to adjust analyses for confounding variables. As the diagnostic requirements are increasing, more sensitive and sophisticated radiological methods, such as high-resolution computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy, may be required for the early recognition of occupational health risks. This necessitates good cooperation between occupational health units and well-equipped imaging dept.s. Considering occupational problems in radiology departments, the increasing use of digital radiology requires ergonomic measures to control and prevent locomotive problems caused by work with computers. Radiation protection measures are still worth concern, especially in interventional radiology

Psychosocial discomfort may amplify job-related risk factors. The aim of this study is to evaluate job stress in a high fashion clothing company with upper limb biomechanical overload due to repetitive and forceful manual activities. Biomechanical risk was analyzed and in part reduced using the OCRA Check list. A total of 518 workers (433 females and 85 males) were investigated to determine anxiety (by STAI 1 and 2), occupational stress (using the Italian version of the Karasek Job Content Questionnaire) and perception of symptoms. Final biomechanical assessment did not reveal high risk jobs, except for cutting. Although the perception of anxiety and job insecurity was within the normal range, all the workers showed a high level of job strain (correlated with the perception of symptoms) due, probably, to very low decision latitude. It was suggested that job strain may increase the perception of symptoms. Moreover, the result of this study indicates that musculoskeletal overload has to be further analyzed since its low level is not in agreement with the level of discomfort due to the repetitive tasks.

Cho, Yeong Ho; Kang, Chang Sun

1998-01-01

The cost-effective reduction of occupational radiation exposure (ORE) dose at a nuclear power plant could not be achieved without going through an extensive analysis of accumulated ORE dose data of existing plants. It is necessary to identify what are high ORE jobs for ALARA implementation. In this study, the Rank Sum Method (RSM) is used in identifying high ORE jobs. As a case study, the database of ORE-related maintenance and repair jobs for Kori Units 3 and 4 is used for assessment, and top twenty high ORE jobs are identified. The results are also verified and validated using the Friedman test, and RSM is found to be a very efficient way of analyzing the data. (author)

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.

Abstract Background: Improving employees’ perception of organizational climate, and coaching them to remain steadfast when managing occupational risks associated with their job, might have an important effect on their psychosocial wellbeing and occupational health. This study examined the effects of a rational emotive occupational health therapy intervention program on the perceptions of organizational climate and occupational risk management practices. Methods: The participants were 77 electronics technology employees in the south-east of Nigeria. The study used a pretest–posttest control group design. Results: The rational emotive occupational health therapy intervention program significantly improved perceptions of the organizational climate for the people in the treatment group compared to those in the waitlist control group at post-intervention and follow-up assessments. Occupational risk management practices of the employees in the treatment group were also significantly better than those in the waitlist control group at the same 2 assessments. Conclusions: Corporate application of a rational emotive behavior therapy as an occupational health therapy intervention program is essential for improving the perceptions of organizational climate and promoting the adoption of feasible occupational risk management strategies in the workplace.

Ahier, B.

2009-01-01

Occupational exposures at nuclear power plants worldwide have steadily decreased since the early 1990's. Regulatory pressures, technological advances, improved plant designs and operational procedures, as low as reasonably achievable (ALARA) culture and information exchange have contributed to this downward trend. However, with the continued ageing and possible life extensions of nuclear power plants, ongoing economic pressures, regulatory, social and political evolutions, and the potential of new nuclear build, the task of ensuring that occupational exposures are kept as low as reasonably achievable continues to present challenges to radiological protection professionals

Objective: Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness. Methods: A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions. Results: 1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ(2)=9.880, P =0.002) , 6 kHz increased by 15.47% (χ(2)=9.985, P =0.002) and 4 kHz+6 kHz increased by15.47% (χ(2)=9.985, P =0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ(2)=3.380, P =0.050; B group χ(2)=4.054, P =0.032) , weighted 6 kHz (A group χ(2)=6.362, P =0.012; B group χ(2

2016-03-01

Occupational skin diseases (OSDs) represent 10-40% of all occupational diseases in many industrialized countries. Young workers are frequently exposed to toxic substances and chemicals in the workplace. The occupational conditions of young workers can impose a high level of risk for the occurrence of OSDs. The Nordic Occupational Skin Questionnaire (NOSQ-2002) was developed in English as a new, comprehensive, standardized tool with which to screen for OSDs. The purpose of this study was to translate the NOSQ-2002 into Turkish and to culturally adapt the long version of the instrument for use with young workers in jobs with high risk for the occurrence of OSDs. Forward and back translations were carried out. Problematic items were modified until the Turkish-language version achieved a satisfactory consensus with the original version of the NOSQ-2002. The final Turkish version was tested in 40 randomly selected young workers with and without OSDs who were studying in the fields of hairdressing, jewelry making, and car mechanics at vocational training schools run by the National Education Ministry. When the original questionnaire had been translated into the target language, a first consensus version was evaluated by an expert panel. The expert panel determined that 36 questions (63.2%) in the Turkish version required some level of modification in order to facilitate clear understanding. Cognitive interviews were then performed. After some modification, the final Turkish version was established and tested among young workers. The new Turkish version of the NOSQ is a comprehensible, reliable, and useful tool that can be applied to young workers in specific occupations. © 2015 The International Society of Dermatology.

Thwarting Nonintrusive Occupancy Detection Attacks from Smart Meters

Directory of Open Access Journals (Sweden)

Dapeng Man

2017-01-01

Full Text Available Occupancy information is one of the most important privacy issues of a home. Unfortunately, an attacker is able to detect occupancy from smart meter data. The current battery-based load hiding (BLH methods cannot solve this problem. To thwart occupancy detection attacks, we propose a framework of battery-based schemes to prevent occupancy detection (BPOD. BPOD monitors the power consumption of a home and detects the occupancy in real time. According to the detection result, BPOD modifies those statistical metrics of power consumption, which highly correlate with the occupancy by charging or discharging a battery, creating a delusion that the home is always occupied. We evaluate BPOD in a simulation using several real-world smart meter datasets. Our experiment results show that BPOD effectively prevents the threshold-based and classifier-based occupancy detection attacks. Furthermore, BPOD is also able to prevent nonintrusive appliance load monitoring attacks (NILM as a side-effect of thwarting detection attacks.

To estimate the prevalence of occupational injuries and identify their risk factors among students in two municipalities. A cross-sectional survey was conducted in public schools of the municipalities of Santo Antonio do Pinhal and Monteiro Lobato, Brazil. A stratified probabilistic sample was drawn from public middle and high schools of the study municipalities. A total of 781 students aged 11 to 19 years participated in the study. Students attending middle and high school answered a comprehensive questionnaire on living and working conditions, as well as aspects of work injuries, and health conditions. Multiple logistic regression models were fitted to estimate risk factors of previous and present occupational injuries. Of 781 students, 604 previously had or currently have jobs and 47% reported previous injuries. Among current workers (n=555), 38% reported injuries on their current job. Risk factors for work injuries with statistically significant odds ratio >2.0 included attending evening school, working as a housekeeper, waiter or brickmaker, and with potentially dangerous machines. The study results reinforce the need of restricting adolescent work and support communities to implement social promotion programs.

Precautions used by occupational health nursing students during clinical placements

Full Text Available Protection of health care workers including students from being infected when caring for high risk patients is a major cause for concern to all promoting occupational health. Safety of every employee is mandatory. Furthermore, universal guidelines for precautions must be used by all interacting with high risk patients and clients to protect themselves and prevent the spread of infection. The aim of this paper was to ascertain the availability of universal guidelines for precautions against the spread of infection in clinical settings and determine the precautions used by OHN students during their clinical placements. To realise these objectives, a quantitative and descriptive design was followed. A purposive sampling method was used to select 45 Occupational health nursing students who participated in the study. Data was collected with the use of a structured questionnaire and the results revealed that: most units where OHN students were placed for clinical experience had guidelines for universal precautions although these were not always accessible to them; regarding compliance to universal precautions, OHN students were reportedly aware of the hazards of failure to comply although in some emergencies and where personal protective material was not available, they had to provide care without using protective equipments. Recommendations made include that employers and staff at all occupational settings must ensure that updated guidelines for universal precautions are available and accessible to every body interacting with high risk patients; health care providers and students must be fully informed about and should always adhere to universal precautions.

2016-07-01

The literature reports on high-frequency audiometry as one of the exams used on hearing monitoring of individuals exposed to high sound pressure in their work environment, due to the method́s greater sensitivity in early identification of hearing loss caused by noise. The frequencies that compose the exam are generally between 9 KHz and 20KHz, depending on the equipment. This study aims to perform a retrospective and secondary systematic revision of publications on high-frequency audiometry on hearing monitoring of individuals exposed to occupational noise. This systematic revision followed the methodology proposed in the Cochrane Handbook, focusing on the question: "Is High-frequency Audiometry more sensitive than Conventional Audiometry in the screening of early hearing loss individuals exposed to occupational noise?" The search was based on PubMed data, Base, Web of Science (Capes), Biblioteca Virtual em Saúde (BVS), and in the references cited in identified and selected articles. The search resulted in 6059 articles in total. Of these, only six studies were compatible with the criteria proposed in this study. The performed meta-analysis does not definitively answer the study's proposed question. It indicates that the 16 KHz high frequency audiometry (HFA) frequency is sensitive in early identification of hearing loss in the control group (medium difference (MD = 8.33)), as well as the 4 KHz frequency (CA), this one being a little less expressive (MD = 5.72). Thus, others studies are necessary to confirm the HFA importance for the early screening of hearing loss on individuals exposed to noise at the workplace.

Full Text Available It has been observed that the construction industry is one of the notorious industry having higher rate of fatalities and injuries. Resulting in higher financial losses and work hour losses, which are normally faced by this industry due to occuptional accidents. Construction industry has the highest occupational accidents rate recorded throughout the world after agriculture industry. The construction work site is often a busy place having an incredibly high account of activities taking place, where everyone is moving in frenzy having particular task assigned. In such an environment, occupational accidents do occur. This paper gives information about different types of occupational accidents & their causes in the construction industry of Pakistan. A survey has been carried out to identify the types of occupational accidents often occur at construction site. The impact of each occupational accident has also been identified. The input from the different stakeholders involved on the work site was analyzed using RIW (Relative Importance Weight method. The findings of this research show that ?fall from elevation, electrocution from building power and snake bite? are the frequent occupational accidents occur within the work site where as ?fall from elevation, struck by, snake bite and electrocution from faulty tool? are the occupational accident with high impact within the construction industry of Pakistan. The results also shows the final ranking of the accidents based on higher frequency and higher impact. Poor Management, Human Element and Poor Site Condition are found as the root causes leading to such occupational accidents. Hence, this paper

In 1976, the 250 MW Gundremmingen nuclear power station (KRB) completed its first decade of operation. The accumulated activity built-up due to corrosion products in the primary system, the condition of the plant and the methods of radiation work management determine the occupational exposure. The development and the general features of these three parameters are presented in detail. Job related exposure accounting has proven to be an effective means of radiation management. By this means up to 90% of the total radiation exposure could be traced with an accuracy of about 10 mrem. It is shown that up to 40% of the total exposure originate not from primary work but from associating jobs, e.g. work area preparation and testing efforts. Especially in this field a remarkable reduction of the occupational dose rate can be achieved by precise planning. The ten-year radiation protection history of KRB served as a design basis with the objective to reduce occupational radiation exposure. Examples are given how this influenced not only the design of relevant systems but also their accomodation, arrangement and shielding with regard to maintenance and repair work during reactor outage. Physical separation of the components and valves from the associated actuators, controls and instruments was provided to reduce personnel radiation exposure during plant operation. Provisions were also made to avoid contamination of the building atmosphere and to reduce the release of radioactivity via the ventilation systems

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. 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. 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). 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 areas where exposures to carcinogenic agents

The specific problem considered in this paper is what are the key issues to consider for managers involved in designing high-trust organizations, a design problem still not properly explored. This paper intends to take the first step in filling this lacuna. In the paper, I first present...... the existing management and research literature on building high-trust organizations. Then I explore Alan Fox’s (1974) analysis of low-trust vs. high-trust dynamics which, I argue, may serve as a theoretically stronger basis for understanding the issues management have to consider when designing hightrust...... organizations...

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.

Full Text Available Environmental exposures of workplace may affect employees' health including the nervous and psychological systems. Aim of this study was to determine the effects of occupational factors on psychological and neurological systems in workplaces. This is historical cohort study on employees in low and high exposure groups. The study's tool was flexible interview, questionnaire and occupational factors measurement. Sick employees were followed until the end of treatment. Headache was higher in employees with high level of lighting. The relative risk was 1.45 (1.04-2.02. Dizziness was significantly more in the working hours in offices. The risk ratio for dizziness was 2.25 (1.80-2.33. Employees with high exposure to occupational factors were at higher risk for headache and dizziness. There is relationship between loss of concentration and age. The risk ratio was 1.63 (1.13-2.36. The results of this study indicated that people who exposed to occupational and environmental pollutants occupational might be a risk for some psychological and neurological symptoms such as headache and dizziness and impaired concentration would be increased by aging.

This study aimed to examine the relationship between work stress and depression; and investigate the mediating effect of occupational burnout among nurses in paediatric intensive care units. The relationships among work stress, occupational burnout and depression level have been explored, neither regarding occupational burnout as the mediating role that causes work stress to induce depression nor considering the paediatric intensive care unit context. A cross-sectional correlational design was conducted. One hundred and forty-four female paediatric intensive care unit nurses from seven teaching hospitals in southern Taiwan were recruited as the participants. Data were collected by structured questionnaires including individual demographics, the Nurse Stress Checklist, the Occupational Burnout Inventory and the Taiwan Depression Questionnaire. The results indicated that after controlling for individual demographic variables, the correlations of work stress with occupational burnout, as well as work stress and occupational burnout with depression level were all positive. Furthermore, occupational burnout may exert a partial mediating effect on the relationship between work stress and depression level. This study provides information about work stress, occupational burnout and depression level, and their correlations, as well as the mediating role of occupational burnout among paediatric intensive care unit nurses. It suggests government departments and hospital administrators when formulating interventions to prevent work stress and occupational burnout. These interventions can subsequently prevent episodes of depression in paediatric intensive care unit nurses, thereby providing patients with a safe and high-quality nursing environment. © 2016 John Wiley & Sons Ltd.

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.

Frequent flyer business travelers. The role of the occupational health nurse.

Science.gov (United States)

Tompkins, Olga S; Randolph, Susan A; Ostendorf, Judith S

2005-03-01

When managing frequent flyer business travelers, occupational health nurses focus on health promotion and health protection goals. The three types of prevention (i.e., primary, secondary, tertiary) follow a timeline beginning with complete prevention, and proceeding through and ending with management of a disease process. Occupational health nurses design and implement practice strategies based on this progression. Travel health nursing is rapidly expanding as the number of travelers, immunizations, and modes of transportation increase. Physicians focus on disease, industrial hygienists focus on hazard exposure, and safety professionals address occupational issues related to illnesses and injuries. Occupational health nurses are the professionals who focus on all three areas, in addition to health promotion and health protection. Frequent flyer business travelers have specific and complex needs that occupational health nurses are in a unique position to address.

The objective of the study was to examine the association between occupational exposure to pesticides and cutaneous melanoma, controlling for all possible confounders. A pooled analysis of two case-control studies was conducted in two different geographic areas (Italy and Brazil). Detailed pesticides exposure histories were obtained. Ever use of any pesticide was associated with a high risk of cutaneous melanoma (odds ratio 2.58; 95% confidence interval 1.18-5.65) in particular exposure to herbicides (glyphosate) and fungicides (mancozeb, maneb), after controlling for confounding factors. When subjects were exposed to both pesticides and occupational sun exposure, the risk increased even more (odds ratio 4.68; 95% confidence interval 1.29-17.0). The study suggests an augmented risk of cutaneous melanoma among subjects with exposure to pesticides, in particular among those exposed to occupational sun exposure.

Rahman, Mohammad Arifur; Rossner, Alan; Hopke, Philip K

2017-06-01

An exposure assessment was conducted to investigate the potential for harmful concentrations of airborne short chain aldehydes emitted from recently stored wood pellets. Wood pellets can emit a number of airborne aldehydes include acetaldehyde, formaldehyde, propionaldehyde, butyraldehyde, valeraldehyde, and hexanal. Exposure limits have been set for these compounds since they can result in significant irritation of the upper respiratory system at elevated concentrations. Formaldehyde is a recognized human carcinogen and acetaldehyde is an animal carcinogen. Thus, air sampling was performed in a wood pellet warehouse at a pellet mill, two residential homes with bulk wood pellet storage bins, and in controlled laboratory experiments to evaluate the risk to occupants. Using NIOSH method 2539, sampling was conducted in five locations in the warehouse from April-June 2016 when it contained varying quantities of bagged pellets as well as two homes with ten ton bulk storage bins. The aldehyde concentrations were found to increase with the amount of stored pellets. Airborne concentrations of formaldehyde were as high as 0.45 ppm in the warehouse exceeding the NIOSH REL-C, and ACGIH TLV-C occupational exposure limits (OELs). The concentrations of aldehydes measured in the residential bins were also elevated indicating emissions may raise indoor air quality concerns for occupants. While individual exposures are of concern the combined irritant effect of all the aldehydes is a further raise the concerns for building occupants. To minimize exposure and the risk of adverse health effects to a building's occupants in storage areas with large quantities of pellets, adequate ventilation must be designed into storage areas.

Davis, Brad E

2011-01-01

The goal of this study was to understand successes and weaknesses of a rooftop hospital garden used primarily for physical therapy. Literature on the healing benefits of nature and designed outdoor spaces in healthcare contexts continues to become more focused on specific patient populations. This study contributes to the knowledge of rooftop hospital gardens and gardens for physical rehabilitation. A post-occupancy evaluation was conducted using interviews with a lead therapist and landscape architect, behavior mapping, a staff survey, and a patient questionnaire. The designer and administrative staff perceived high accessibility while patients and staff reported low accessibility. Patients reported high satisfaction with the garden while staff reported little time for garden use. Poor maintenance decisions resulted in decreased functional and aesthetic value. Garden elements take on added layers of meaning and value to users seeking to escape the indoor environment, placing increased importance on evidence-based site design. Multiple perspectives must be considered in facility and garden master planning. Finally, designers and horticultural therapists must be retained in garden management to preserve and enhance garden functionality.

Full Text Available The purpose of this study was to examine whether second-year Master of Occupational Therapy (MOT students who enroll in the elective course “Occupation in Long-Term Care (LTC” would be able to apply concepts of occupational justice in the nursing home environment through engaging residents in occupational storytelling and story making in order to facilitate resident self-advocacy for participation in a valued occupation. The occupational therapy elective course was developed and implemented with students alternating between the classroom and the nursing home environments. Outcome evaluation measurements included analysis of student reflective journaling to obtain qualitative data. The researcher found that students are able to understand the concepts and issues of occupational justice in the nursing home population and apply knowledge to facilitate the resident’s participation in meaningful occupations.

[Evaluation and prognosis of occupational risk in workers of nonferrous metallurgy enterprises].

Shliapnikov, D M; Kostarev, V G

2014-01-01

The article deals with results of a priori and a posteriori evaluation of occupational risk for workers' health. Categories of a priori occupational risk for workers are estimated as high to very high (intolerable) risk. Findings are that work conditions in nonferrous metallurgy workshop result in upper respiratory tract diseases (medium degree of occupational conditionality). Increased prevalence of such diseases among the workers is connected with length of service. The authors revealed priority factors for occupationally conditioned diseases. A promising approach in occupational medicine is creation of methods to evaluate and forecast occupational risk, that enable to specify goal parameters for prophylactic measures. For example, modelling the risk of occupationally conditioned diseases via changes in exposure to occupational factor and length of service proved that decrease of chemical concentrations in air of workplace to maximally allowable ones lowers risk of respiratory diseases from 14 to 6 cases per year, for length of service of 5 years and population risk.

1. Worldwide loss of biodiversity necessitates a clear understanding of the factors driving population declines as well as informed predictions about which species and populations are at greatest risk. The biggest threat to the long-term persistence of populations is the reduction and changes in configuration of their natural habitat. 2. Inconsistencies have been noted in the responses of populations to the combined effects of habitat loss and fragmentation. These have been widely attributed to the effects of the matrix habitats in which remnant focal habitats are typically embedded. 3. We quantified the potential effects of the inter-patch matrix by estimating occupancy and colonization of forest and surrounding non-forest matrix (NF). We estimated species-specific parameters using a dynamic, multi-species hierarchical model on a bird community in southwestern Costa Rica. 4. Overall, we found higher probabilities of occupancy and colonization of forest relative to the NF across bird species, including those previously categorized as open habitat generalists not needing forest to persist. Forest dependency was a poor predictor of occupancy dynamics in our study region, largely predicting occupancy and colonization of only non-forest habitats. 5. Our results indicate that the protection of remnant forest habitats is key for the long-term persistence of all members of the bird community in this fragmented landscape, including species typically associated with open, non-forest habitats. 6.Synthesis and applications. We identified 39 bird species of conservation concern defined by having high estimates of forest occupancy, and low estimates of occupancy and colonization of non-forest. These species survive in forest but are unlikely to venture out into open, non-forested habitats, therefore, they are vulnerable to the effects of habitat loss and fragmentation. Our hierarchical community-level model can be used to estimate species-specific occupancy dynamics for focal

The Portrayal of Occupational Therapy and Occupational Science in Canadian Newspapers: A Content Analysis

2016-05-01

Full Text Available The primary goal of occupational therapy is to enable people to participate in the activities of everyday life. The demand for occupational therapists in Canada is expected to grow sharply at an annual growth rate of 3.2%, compared to 0.7% for all occupations. At the same time, it is believed by occupational therapists in Canada that the Canadian public does not understand the role of occupational therapy. Occupational science is an emerging basic science field that supports the practice of occupational therapy. Given that newspapers are one source the public uses to obtain information and that newspapers are seen to shape public opinions, the purpose of this study is to investigate how “occupational therapy” is covered in Canadian newspapers from the term’s first appearance in 1917 until 2016 and how “occupational science” is covered from the term’s first appearance in 1989 to 2016. We interrogated the findings through the lens of three non-newspaper sources—two academic journals: Canadian Journal of Occupational Therapy (CJOT and Journal of Occupational Science (JOS; and one Canadian magazine: Occupational Therapy Now (OTN. We found that medical terms were prevalent in the newspaper articles covering occupational therapy similar to the presence of medical terms in the CJOT and OTN. However, the newspapers missed contemporary shifts in occupational therapy as evident in the CJOT, OTN and JOS—such as the increased engagement with enablement, occupational justice and other occupational concepts. The newspapers also failed to portray the societal issues that occupational therapy engages with on behalf of and with their clients, and the newspapers did not cover many of the client groups of occupational therapy. Occupational science was only mentioned in n = 26 articles of the nearly 300 Canadian newspapers covered with no concrete content linked to occupational science.

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.

Self-reported outcome instruments in health research have become increasingly important over the last decades. Occupational therapy interventions often focus on occupational balance. However, instruments to measure occupational balance are scarce. The aim of the study was therefore to develop a generic self-reported outcome instrument to assess occupational balance based on the experiences of patients and healthy people including an examination of its psychometric properties. We conducted a qualitative analysis of the life stories of 90 people with and without chronic autoimmune diseases to identify components of occupational balance. Based on these components, the Occupational Balance-Questionnaire (OB-Quest) was developed. Construct validity and internal consistency of the OB-Quest were examined in quantitative data. We used Rasch analyses to determine overall fit of the items to the Rasch model, person separation index and potential differential item functioning. Dimensionality testing was conducted by the use of t-tests and Cronbach's alpha. The following components emerged from the qualitative analyses: challenging and relaxing activities, activities with acknowledgement by the individual and by the sociocultural context, impact of health condition on activities, involvement in stressful activities and fewer stressing activities, rest and sleep, variety of activities, adaptation of activities according to changed living conditions and activities intended to care for oneself and for others. Based on these, the seven items of the questionnaire (OB-Quest) were developed. 251 people (132 with rheumatoid arthritis, 43 with systematic lupus erythematous and 76 healthy) filled in the OB-Quest. Dimensionality testing indicated multidimensionality of the questionnaire (t = 0.58, and 1.66 after item reduction, non-significant). The item on the component rest and sleep showed differential item functioning (health condition and age). Person separation index was 0

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

van Mechelen Willem

2007-07-01

Full Text Available Abstract Background Mental health problems often lead to prolonged sick leave. In primary care, the usual approach towards these patients was the advice to take rest and not return to work before all complaints had disappeared. When complaints persist, these patients are often referred to psychologists from primary and specialized secondary care. As an alternative, ways have been sought to activate the Dutch occupational physician (OP in primary care. Early 2000, the Dutch Association of Occupational Physicians (NVAB published a guideline concerning the management by OPs of employees with mental health problems. The guideline received positive reactions from employees, employers and Dutch OPs. This manuscript describes the design of a study, which aims to assess the effects of the guideline, compared with usual care. Methods/Design In a randomized controlled trial (RCT, subjects in the intervention group were treated according to the guideline. The control group received usual care, with minimal involvement of the OP and easy access to a psychologist. Subjects were recruited from two Dutch police departments. The primary outcomes of the study are return to work and treatment satisfaction by the employee, employer, and OP. A secondary outcome is cost-effectiveness of the intervention, compared with usual care. Furthermore, prognostic measures are taken into account as potential confounders. A process evaluation will be done by means of performance indicators, based on the guideline. Discussion In this pragmatic trial, effectiveness instead of efficacy is studied. We will evaluate what is possible in real clinical practice, rather than under ideal circumstances. Many requirements for a high quality trial are being met. Results of this study will contribute to treatment options in occupational health practice for employees on sick leave due to mental health problems.

High-frequency Audiometry Hearing on Monitoring of Individuals Exposed to Occupational Noise: A Systematic Review

Directory of Open Access Journals (Sweden)

Antonioli, Cleonice Aparecida Silva

2015-12-01

Full Text Available Introduction The literature reports on high-frequency audiometry as one of the exams used on hearing monitoring of individuals exposed to high sound pressure in their work environment, due to the method́s greater sensitivity in early identification of hearing loss caused by noise. The frequencies that compose the exam are generally between 9 KHz and 20KHz, depending on the equipment. Objective This study aims to perform a retrospective and secondary systematic revision of publications on high-frequency audiometry on hearing monitoring of individuals exposed to occupational noise. Data Synthesis This systematic revision followed the methodology proposed in the Cochrane Handbook, focusing on the question: “Is High-frequency Audiometry more sensitive than Conventional Audiometry in the screening of early hearing loss individuals exposed to occupational noise?” The search was based on PubMed data, Base, Web of Science (Capes, Biblioteca Virtual em Saúde (BVS, and in the references cited in identified and selected articles. The search resulted in 6059 articles in total. Of these, only six studies were compatible with the criteria proposed in this study. Conclusion The performed meta-analysis does not definitively answer the study's proposed question. It indicates that the 16 KHz high frequency audiometry (HFA frequency is sensitive in early identification of hearing loss in the control group (medium difference (MD = 8.33, as well as the 4 KHz frequency (CA, this one being a little less expressive (MD = 5.72. Thus, others studies are necessary to confirm the HFA importance for the early screening of hearing loss on individuals exposed to noise at the workplace.

The competencies required of occupational physicians (OPs) and occupational health nurses (OHNs) separately have been studied in various countries but little research has made direct comparisons between these two key occupational health (OH) professional groups. The aim of this study was to compare current competency priorities between UK OPs and OHNs. A modified Delphi study conducted among professional organisations and networks of UK OPs and OHNs. This formed part of a larger Delphi, including international OPs. It was undertaken in two rounds (round 1-'rating', round 2-'ranking'), using a questionnaire based on available OH competency guidance, the literature, expert panel reviews and conference discussions. In each round (rating/ranking), 57/49 and 48/54 responses were received for OPs and OHNs respectively. The principle domain (PD) competency ranks were very highly correlated (Spearman's r=0.972) with the same PDs featuring in the top four and bottom three positions. OPs and OHNs ranked identically for the top two PDs (good clinical care and general principles of assessment and management of occupational hazards to health). Research methods was ranked lowest by both groups. This study has observed a high level of agreement among UK OPs and OHNs on current competency priorities. The 'clinically focused' competency priorities likely reflect that although OH practice will broaden in response to various factors, traditional 'core' OH activities will still be required. These mutually identified priorities can serve to strengthen collaboration between these groups, develop joint education/training programmes and identify common professional development opportunities. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Horie, Seichi

2013-10-01

In Japan, an employer of a workplace with 50 or more employees is legally required to assign an occupational health physician. The assignment rate in 2010 was reported as 87.0%. This policy started with the provision of "factory physician"in the Factory Law in 1938, then the Labour Standard Law stipulated "physician hygienist" in 1947, and finally the Industrial Safety and Health Law defined "occupational health physician" in 1972. In 1996, a revision of the law then required those physicians to complete training courses in occupational medicine, as designated by an ordinance. Historically, an on-site physician was expected to cure injuries and to prevent communicable diseases of factory workers. The means of occupational hygienic management by working environment measurements, etc., and of health management by health examinations, etc., were developed. Localized exhaust ventilation and personal protection equipment became widely utilized. Qualification systems for non-medical experts in occupational hygiene were structured, and relationships between employers and occupational health physicians were stipulated in the legislative documents. Currently, the Japan Medical Association and the University of Occupational and Environmental Health, Japan educate and train occupational health physicians, and the Japan Society for Occupational Health maintains a specialized board certification system for these physicians. In the future, additional efforts should be made to strengthen the expertise of occupational health physicians, to define and recognize the roles of non-medical experts in occupational hygiene, to incorporate occupational health services in small enterprises, to promote occupational health risk assessment in the workplace, and to reorganize the current legislation, amended repeatedly over the decades.

Xie, Manxia; Zhou, Jin; Wang, Yimei

2015-10-01

To investigate the status and risk factors for hematogenous occupational exposure in medical staff in an infectious disease hospital, and to provide a scientific basis for targeted preventive and control measures. The occupational exposure of 395 medical workers in our hospital was monitored from January 2012 to December 2014, among whom 79 individuals with occupational exposure were subjected to intervention and the risk factors for occupational exposure were analyzed. The high-risk group was mainly the nursing staff (69.6%). The incidence of hematogenous occupational exposure was high in medical personnel with a working age under 3 years, aged under 25 years, and at the infection ward, accounting for 63.3%, 72.1%, and 72.2%, respectively. Hepatitis B virus, hepatitis C virus, Treponema pallidum, and human immunodeficiency virus were the primary exposure sources. Sharp injury was the major way of injury (91.1%), with needle stick injury accounting for the highest proportion (86.1%). Injury occurred on the hand most frequently (91.1%). The high-risk links were improper disposal during or after pulling the needle, re-capturing the needle, and processing waste, accounting for 46.8%, 17.7%, and 12.7%, respectively. Seventy-nine professionals with occupational exposure were not infected. The main risk factor for hematogenous occupational exposure in medical staff in the infectious disease hospital is needle stick injury. Strengthening the occupational protection education in medical staff in infectious disease hospital, implementing protective measures, standardizing operating procedures in high-risk links, and enhancing the supervision mechanism can reduce the incidence of occupational exposure and infection after exposure.

Occupational stress in the ED: a systematic literature review.

Basu, Subhashis; Qayyum, Hasan; Mason, Suzanne

2017-07-01

Occupational stress is a major modern health and safety challenges. While the ED is known to be a high-pressure environment, the specific organisational stressors which affect ED staff have not been established. We conducted a systematic review of literature examining the sources of organisational stress in the ED, their link to adverse health outcomes and interventions designed to address them. A narrative review of contextual factors that may contribute to occupational stress was also performed. All articles written in English, French or Spanish were eligible for conclusion. Study quality was graded using a modified version of the Newcastle-Ottawa Scale. Twenty-five full-text articles were eligible for inclusion in our systematic review. Most were of moderate quality, with two low-quality and two high-quality studies, respectively. While high demand and low job control were commonly featured, other studies demonstrated the role of insufficient support at work, effort-reward imbalance and organisational injustice in the development of adverse health and occupational outcomes. We found only one intervention in a peer-reviewed journal evaluating a stress reduction programme in ED staff. Our review provides a guide to developing interventions that target the origins of stress in the ED. It suggests that those which reduce demand and increase workers' control over their job, improve managerial support, establish better working relationships and make workers' feel more valued for their efforts could be beneficial. We have detailed examples of successful interventions from other fields which may be applicable to this setting. Published by the BMJ Publishing Group Limited.

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 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.

Measuring indoor occupancy in intelligent buildings using the fusion of vision sensors

International Nuclear Information System (INIS)

Liu, Dixin; Guan, Xiaohong; Du, Youtian; Zhao, Qianchuan

2013-01-01

In intelligent buildings, practical sensing systems designed to gather indoor occupancy information play an indispensable role in improving occupant comfort and energy efficiency. In this paper, we propose a novel method for occupancy measurement based on the video surveillance now widely used in buildings. In our method, we analyze occupant detection both at the entrance and inside the room. A two-stage static detector is presented based on both appearances and shapes to find the human heads in rooms, and motion-based technology is used for occupant detection at the entrance. To model the change of occupancy and combine the detection results from multiple vision sensors located at entrances and inside rooms for more accurate occupancy estimation, we propose a dynamic Bayesian network-based method. The detection results of each vision sensor play the role of evidence nodes of this network, and thus, we can estimate the true occupancy at time t using the evidence prior to (and including) time t. Experimental results demonstrate the effectiveness and efficiency of the proposed method. (paper)

[Occupational epidemiology: some methodological considerations].

Science.gov (United States)

Alvear-Galindo, María Guadalupe; del Pilar Paz-Román, María

2006-01-01

During the last decade, occupational epidemiology has gained a great importance, not only because of the increase of pollutants and their noxiousness, but also because it has gone from the descriptive to the analytic level. The purpose of this work is to present what has been reported on epidemiological studies, different ways of characterizing and measuring occupational exposure, by emphasizing slants of exposure and selection measurement. In the reviewed studies, an interest in improving the exposure evaluation has been shown. The mainly reported measurement slants are the ways of measuring and classifying the exposure. The main designs were transversal with the use of matrixes to improve the evaluation of exposure. Conditions of hygiene and security were considered in order to control the quality of the information. This information was analyzed with different criteria. Some of the elements that hinder the research on occupational epidemiology are a mixed exposure, small populations, lack of exposure data, low levels of exposure and long periods of illness latency. Some breakthroughs in the strategies of epidemiological analysis and some other areas of knowledge have made possible a better understanding of work and health conditions of workers.

Personnel in public hospitals had relatively low job satisfaction despite of tenure employment. High turnover rates degrade hospital image and incur additional costs related to recruitment and training. The purposes of this study were to describe the occupational differences and to identify factors affecting turnover intention among public hospital personnel. A questionnaire survey was conducted as part of Administrative Services Quality Evaluation Program by Seoul metropolitan municipality from 1 November to 1 December in 2003. The subjects were 1251 entire hospital personnel in four hospitals. The questionnaire was designed to measure job satisfaction, organizational commitment, turnover intention, and demographic characteristics. Logistic regression analysis was performed to determine factors influencing turnover intention. There were significant differences in job satisfaction, organizational commitment, and turnover intention according to the occupations. The turnover intention rates were highest among physicians, followed by paramedicals and nursing staffs and then administrators. The significant factors affecting turnover intention were involvement and loyalty among physicians, hospital type, satisfaction with systems and loyalty among nursing staffs, satisfaction with relationship and loyalty among administrators, and loyalty among paramedicals. There were different moderators that influence turnover intentions of hospital personnel. Loyalty had the most important effect upon turnover intention in all occupations. 2007 John Wiley & Sons, Ltd

The purpose of this study was to verify whether occupational noise exposure is a significant risk factor for work accidents in the city of Piracicaba, São Paulo State, Brazil. This hospital-based case-control study included 600 workers aged 15-60 who suffered typical occupational accidents between May and October 2004 and were seen at the Piracicaba Orthopedics and Trauma Center. The control group comprised 822 workers, aged 15-60, who were also seen at the Center, and either had a non-occupational accident or were accompanying someone who had suffered an accident. A multiple logistic regression model was adjusted with work accident as an independent variable, controlled by covariables of interest such as noise exposure. The risk of having a work accident was about twice as high among workers exposed to noise, after controlling for several covariables. Occupational noise exposure not only affected auditory health status but was also a risk factor for work accidents.

This paper is a report of an exploration of job stress, achievement motivation and occupational burnout in male nurses and to identify predictors of occupational burnout. Since the Nightingale era, the nursing profession has been recognized as 'women's work'. The data indicate that there are more female nurses than male nurses in Taiwan. However, the turnover rate for male nurses is twice that of female nurses. Understanding the factors that affect occupational burnout of male nurses may help researchers find ways to reduce the likelihood that they will quit. A survey was conducted in Taiwan in 2008 using a cross-sectional design. A total of 121 male nurses participated in the study. Mailed questionnaires were used to collect data, which were analysed using descriptive statistics and stepwise multiple regression. The job stress of male nurses was strongly correlated with occupational burnout (r = 0.64, P job stress was the only factor to have a statistically significant direct influence on occupational burnout, accounting for 45.8% of the variance in this. Job stress was comprised of three dimensions, of which role conflict accounted for 40.8% of the variance in occupational burnout. The contribution of job stress to occupational burnout of male nurses was confirmed. As occupational burnout may influence the quality of care by these nurses, nurse managers should strive to decrease male nurses' job stress as this should lead to a reduction of negative outcomes of occupational burnout.

Simulation in Occupational Therapy Curricula: A literature review.

Bennett, Sally; Rodger, Sylvia; Fitzgerald, Cate; Gibson, Libby

2017-08-01

Simulated learning experiences are increasingly being used in health-care education to enhance student engagement and provide experiences that reflect clinical practice; however, simulation has not been widely investigated in occupational therapy curricula. The aim of this paper was to: (i) describe the existing research about the use and evaluation of simulation over the last three decades in occupational therapy curricula and (ii) consider how simulation has been used to develop competence in students. A literature review was undertaken with searches of MEDLINE, CINAHL and ERIC to locate articles that described or evaluated the use of simulation in occupational therapy curricula. Fifty-seven papers were identified. Occupational therapy educators have used the full scope of simulation modalities, including written case studies (22), standardised patients (13), video case studies (15), computer-based and virtual reality cases (7), role-play (8) and mannequins and part-task trainers (4). Ten studies used combinations of these modalities and two papers compared modalities. Most papers described the use of simulation for foundational courses, as for preparation for fieldwork, and to address competencies necessary for newly graduating therapists. The majority of studies were descriptive, used pre-post design, or were student's perceptions of the value of simulation. Simulation-based education has been used for a wide range of purposes in occupational therapy curricula and appears to be well received. Randomised controlled trials are needed to more accurately understand the effects of simulation not just for occupational therapy students but for longer term outcomes in clinical practice. © 2017 Occupational Therapy Australia.

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.

Ryu, Hosihn; Moon, Jihyeon; Jung, Jiyeon

2018-06-14

This study examined the influence of health behaviors and occupational stress on the prediabetic state of male office workers, and identified related risks and influencing factors. The study used a cross-sectional design and performed an integrative analysis on data from regular health checkups, health questionnaires, and a health behavior-related survey of employees of a company, using Spearman’s correlation coefficients and multiple logistic regression analysis. The results showed significant relationships of prediabetic state with health behaviors and occupational stress. Among health behaviors, a diet without vegetables and fruits (Odds Ratio (OR) = 3.74, 95% Confidence Interval (CI) = 1.93⁻7.66) was associated with a high risk of prediabetic state. In the subscales on occupational stress, organizational system in the 4th quartile (OR = 4.83, 95% CI = 2.40⁻9.70) was significantly associated with an increased likelihood of prediabetic state. To identify influencing factors of prediabetic state, the multiple logistic regression was performed using regression models. The results showed that dietary habits (β = 1.20, p = 0.002), total occupational stress score (β = 1.33, p = 0.024), and organizational system (β = 1.13, p = 0.009) were significant influencing factors. The present findings indicate that active interventions are needed at workplace for the systematic and comprehensive management of health behaviors and occupational stress that influence prediabetic state of office workers.

Using occupancy models to investigate the prevalence of ectoparasitic vectors on hosts: an example with fleas on prairie dogs

Eads, David A.; Biggins, Dean E.; Doherty, Paul F.; Gage, Kenneth L.; Huyvaert, Kathryn P.; Long, Dustin H.; Antolin, Michael F.

2013-01-01

Ectoparasites are often difficult to detect in the field. We developed a method that can be used with occupancy models to estimate the prevalence of ectoparasites on hosts, and to investigate factors that influence rates of ectoparasite occupancy while accounting for imperfect detection. We describe the approach using a study of fleas (Siphonaptera) on black-tailed prairie dogs (Cynomys ludovicianus). During each primary occasion (monthly trapping events), we combed a prairie dog three consecutive times to detect fleas (15 s/combing). We used robust design occupancy modeling to evaluate hypotheses for factors that might correlate with the occurrence of fleas on prairie dogs, and factors that might influence the rate at which prairie dogs are colonized by fleas. Our combing method was highly effective; dislodged fleas fell into a tub of water and could not escape, and there was an estimated 99.3% probability of detecting a flea on an occupied host when using three combings. While overall detection was high, the probability of detection was always dogs, flea occupancy was heightened in old/natural colonies of prairie dogs, and on hosts that were in poor condition. Occupancy was initially low in plots with high densities of prairie dogs, but, as the study progressed, the rate of flea colonization increased in plots with high densities of prairie dogs in particular. Our methodology can be used to improve studies of ectoparasites, especially when the probability of detection is low. Moreover, the method can be modified to investigate the co-occurrence of ectoparasite species, and community level factors such as species richness and interspecific interactions.

Integrating occupations: Changing occupational sex segregation in the U.S. from 2000 to 2014

2018-01-01

Full Text Available Background: Declining occupational sex segregation in the late 20th century helped to usher in unprecedented occupational and economic advancement for women. As the 21st century dawned, that advancement stalled. Objective: We examine how occupational integration occurred in the early decades of the 21st century by focusing on (1 the extent of occupational feminization and masculinization and (2 occupational succession. More broadly we examine how the representation of women in detailed occupational categories changed between 2000 and 2014, regardless of whether they were historically 'male' or 'female,' and how sociodemographic characteristics contributed to uneven shifts in occupational integration. Methods: We use Integrated Public Use Microdata Series data to estimate the percentage point female at the detailed occupation level, specifically the 5Š census microdata sample for 2000, and two 1Š American Community Survey (ACS samples for 2013 and 2014. Results: Despite a stall in overall integration, there was much fluctuation within detailed occupations. Moreover, occupational inroads have been uneven in the post-2000 period. Women gained entry into the same types of professional and managerial occupations they entered between 1970 and 2000, especially in the health professions. Men increased their representation in lower-level, nonprofessional occupations. Contribution: Rather than focus solely on predominantly male or female occupations, we focus more broadly on how occupations feminize and masculinize. More occupations masculinized than previously. Moreover, those in feminizing occupations are more likely to be advantaged (e.g., white, citizens, and educated, while those in masculinizing occupations are more likely to be disadvantaged (e.g., black, Hispanic, and poor English speakers.

The aim of this study was to identify determinants of occupational sunburn in agricultural workers and assess their occupational and recreational sun protection habits. Specific surveys of agricultural workers in Switzerland and France were conducted (N = 1538). Multivariate logistic regressions identified occupational sunburn determinants. Occupational and recreational sun protection habits were estimated and correlated. One-year occupational and recreational sunburn prevalences were 19.8% and 11.5%, respectively. Occupational sunburn increased with having a recent recreational sunburn, highly sensitive skin, young age, high perceived skin cancer risk, using sunscreen, and not wearing a hat. Correlation between protection habits during work and leisure was substantial (rs 0.5 to 0.7). Skin health knowledge was high and pro-tanning attitude moderate. Potentially modifiable sunburn determinants and suboptimal recreational and occupational sun protection practices were identified in agricultural workers. Refining and tailoring sun protection messages targeting the agricultural sector are needed.

ABSTRACT: BACKGROUND: Occupational heavy lifting is known to impose a high cardiovascular strain, but the risk of ischemic heart disease (IHD) from occupational heavy lifting is unknown. The objective was to investigate the association between occupational heavy lifting and risk of IHD and all...... cardiovascular disease at baseline. Conventional risk factors for the outcomes IHD and all-cause mortality were controlled for in Cox analyses. RESULTS: Among men, heavy lifting was associated with increased risk for IHD (hazard ratio (HR): 1.52, 95 % Confidence interval (95 % CI): 1.15, 2.02), while a decreased...... risk was associated with occupational (HR: 0.50, 95 % CI: 0.37, 0.68) and leisure time (HR: 0.73, 95 % CI: 0.56, 0.95) physical activity. Referencing men with high occupational physical activity and no heavy lifting, men with high occupational physical activity and heavy lifting did not have...

To consider the appropriate occupational health system for Japanese enterprises in Indonesia with information on the regulations and development of the specialists. In this study, we used the information-gathering checklist developed by Kajiki et al. Along with literature and internet surveys, we surveyed local corporations owned and operated by Indonesians, central government agencies in charge of medical and health issues, a Japanese independent administrative agency supporting subsidiaries of overseas Japanese enterprises, and an educational institution formulating specialized occupational physician training curricula. In Indonesia, the Ministry of Manpower and the Ministry of Health administer occupational health matters. The act No. 1 on safety serves as the fundamental regulation. We confirmed at least 40 respective regulations in pertinent areas, such as the placement of medical and health professionals, health examinations, occupational disease, and occupational health service agencies. There are some regulations that indicate only an outline of activities but not details. Occupational physicians and safety officers are the two professional roles responsible for occupational health activities. A new medical insurance system was started in 2014, and a workers' compensation system was also established in 2017 in Indonesia according to the National Social Security System Act. Although safety and health laws and regulations exist in Indonesia, their details are unclear and the quality of expert human resources needed varies. To conduct high-quality occupational health activities from the standpoint of Japanese companies' headquarters, the active promotion of employing highly specialized professionals and cooperation with educational institutions is recommended.

High-Average, High-Peak Current Injector Design

CERN Document Server

Biedron, S G; Virgo, M

2005-01-01

There is increasing interest in high-average-power (>100 kW), um-range FELs. These machines require high peak current (~1 kA), modest transverse emittance, and beam energies of ~100 MeV. High average currents (~1 A) place additional constraints on the design of the injector. We present a design for an injector intended to produce the required peak currents at the injector, eliminating the need for magnetic compression within the linac. This reduces the potential for beam quality degradation due to CSR and space charge effects within magnetic chicanes.

Architectural design has the potential to influence the microbiology of the built environment, with implications for human health and well-being, but the impact of design on the microbial biogeography of buildings remains poorly understood. In this study we combined microbiological data with information on the function, form, and organization of spaces from a classroom and office building to understand how design choices influence the biogeography of the built environment microbiome. Sequencing of the bacterial 16S gene from dust samples revealed that indoor bacterial communities were extremely diverse, containing more than 32,750 OTUs (operational taxonomic units, 97% sequence similarity cutoff), but most communities were dominated by Proteobacteria, Firmicutes, and Deinococci. Architectural design characteristics related to space type, building arrangement, human use and movement, and ventilation source had a large influence on the structure of bacterial communities. Restrooms contained bacterial communities that were highly distinct from all other rooms, and spaces with high human occupant diversity and a high degree of connectedness to other spaces via ventilation or human movement contained a distinct set of bacterial taxa when compared to spaces with low occupant diversity and low connectedness. Within offices, the source of ventilation air had the greatest effect on bacterial community structure. Our study indicates that humans have a guiding impact on the microbial biodiversity in buildings, both indirectly through the effects of architectural design on microbial community structure, and more directly through the effects of human occupancy and use patterns on the microbes found in different spaces and space types. The impact of design decisions in structuring the indoor microbiome offers the possibility to use ecological knowledge to shape our buildings in a way that will select for an indoor microbiome that promotes our health and well-being.

This study aimed to determine physical performance criteria of different occupational groups by investigating physical activity and energy expenditure in healthy Swiss employees in real-life workplaces on workdays and non-working days in relation to their aerobic capacity (VO2max). In this cross-sectional study, 337 healthy and full-time employed adults were recruited. Participants were classified (nine categories) according to the International Standard Classification of Occupations 1988 and merged into three groups with low-, moderate- and high-intensity occupational activity. Daily steps, energy expenditure, metabolic equivalents and activity at different intensities were measured using the SenseWear Mini armband on seven consecutive days (23 hours/day). VO2max was determined by the 20-meter shuttle run test. Data of 303 subjects were considered for analysis (63% male, mean age: 33 yrs, SD 12), 101 from the low-, 102 from the moderate- and 100 from the high-intensity group. At work, the high-intensity group showed higher energy expenditure, metabolic equivalents, steps and activity at all intensities than the other groups (pphysical activity between the occupational groups on non-working days. VO2max did not differ across groups when stratified for gender. The upper workload limit was 21%, 29% and 44% of VO2max in the low-, moderate- and high-intensity group, respectively. Men had a lower limit than women due to their higher VO2max (26% vs. 37%), when all groups were combined. While this study did confirm that the average workload limit is one third of VO2max, it showed that the average is misrepresenting the actual physical work demands of specific occupational groups, and that it does not account for gender-related differences in relative workload. Therefore, clinical practice needs to consider these differences with regard to a safe return to work, particularly for the high-intensity group. PMID:27136206

The aim was to explore the impact of occupation on chronic obstructive pulmonary disease (COPD) in a cross-sectional population-based study among subjects aged 45 to 84 years. In a stratified sampling 89 general practitioners practices (GPP) in Denmark recruited 3106 males and 1636 females through the Danish Civil Registration System. COPD was defined by spirometry by the 2.5(th)-centile Lower Limit of Normal of FEV1 and FEV1/FVC. Information about smoking, occupational exposure and the respective occupations were obtained from questionnaires. Occupations followed the Danish adaptation of The International Standard Classification of Occupations, revision 1988 (DISCO-88). Exposure to vapour, gas, dust (organic and inorganic), and fume (VGDF) in each occupation (yes/no) was evaluated by two independent specialist in occupational medicine. Exposures were divided in no, low, medium, and high exposure as 0, occupation with VGDF exposure. Adjusted for smoking, age, sex, and GPP a dose-dependent association of COPD was found among workers in jobs with high organic dust exposure, with OR 1.56 (95% CI 1.09-2.24). Restricted to agriculture the OR was 1.59 (95% CI: 1.08-2.33). No association was observed for workers in jobs with inorganic dust, fume/gas, or vapour exposures. In summary, occupational organic dust exposure was associated to the prevalence of COPD.

Occupational therapy practice in emergency care: Occupational therapists' perspectives.

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.

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.

High-Mobility Multipurpose Wheeled Vehicle Rollover Accidents and Injuries to U.S. Army Soldiers by Reported Occupant Restraint Use, 1992-2013.

The high-mobility multipurpose wheeled vehicle (HMMWV) is a light military tactical vehicle. During Operation Iraqi Freedom and Operation Enduring Freedom, the U.S. Army modified the HMMWV into a combat vehicle by adding vehicle armor, which made the vehicle more difficult to control and more likely to roll over. Consequently, reports of fatal rollover accidents involving up-armored HMMWVs began to accumulate during the up-armoring period (August 2003 to April 2005). Furthermore, the lack of occupant restraint use prevalent in a predominantly young, male, and enlisted military population compounded the injuries resulting from these accidents. In this retrospective case series analysis, we describe the characteristics of U.S. Army HMMWV rollover accidents, occupants, and injuries reported worldwide from fiscal year 1992 to 2013 based on reported occupant restraint use. We conducted all analyses using Microsoft Excel 2010 and SAS version 9.1. Because this analysis does not constitute human subjects research, no institutional review board review was required. First, we obtained U.S. Army HMMWV accident records from the U.S. Army Combat Readiness Center, and selected those records indicating a HMMWV rollover had occurred. Next, we successively deduplicated the records at the accident, vehicle, occupant, and injury levels for descriptive analysis of characteristics at each level. For each occupant position, we calculated relative, attributable, and population attributable risks of nonfatal and fatal injury based on reported occupant restraint use. Finally, we analyzed body part injured and nature of injury to characterize the injury patterns that HMMWV occupants in each position sustained based on restraint use. We performed a χ 2 test of homogeneity to assess differences in injury patterns between restrained and unrestrained occupants. A total of 819 U.S. Army HMMWV rollover accidents worldwide were reported from October 1991 through May 2013 involving 821 HMMWVs and

Integration processes after mergers are fraught with difficulties, and constitute a main cause of merger failure. This study focuses on the human aspect of post-merger integration, and in particular, on the role of occupational identification. We theorize and empirically demonstrate by means of a survey design that employees' identification with their occupation is positively related to their willingness to cooperate in the post-merger integration process, over and above the effect of organization members' organizational identification. This positive effect of occupational identification is stronger for uniformed personnel but attenuates in the course of the integration process. Qualitative interviews further explore and interpret the results from our statistical analysis. Together, these findings have important practical implications and suggest future research directions.

Full Text Available Background: The presense of women in workplace is an unavoiding issue in modern world. The women work in different media. Occupational activities are suspected of having an adverse impact on outcomes of pregnancy. Premature delivery is a catastrophic event in course of pregnancy. The aim of the study was to define the incidence of premature delivery in occupationally involved pregnant women. Material and Methods: A total of 287 primigravida women in an urban society with singleton pregnancies at 22 to 24 weeks gestation were enrolled in a prospective study. They worked in industrial manufactures. The patients reported the number of hours worked per week and answered specific questions designed to determine the following 5 sources of occupational fatigue including:1- posture ,2- work with industrial machines 3- physical exertion 4-mental stress and 5- environmental stress. Results: The risk of preterm delivery increased with standing more than 3 hours during activities in work place (p.value=0/019. There was not a statistically significant relationship between premature delivery and other sources of occupational fatigue. There was not a statically significant relationship between premature rupture of fetal membranes and the sources of occupational fatigue. There was not a statistically significant relationship between premature delivery and increasing number of hours worked per week. Conclusion: The relationship between premature delivery and occupational fatigue may provide guidelines according to pregnant women and their employers can be advised.

There are few studies in occupational therapy that compare the perceptions of supervisors and students regarding quality clinical placement programmes, and those that exist indicate substantial differences in the perceptions held by each group. This pilot study was conducted using a cross-sectional descriptive design, with a single questionnaire distributed to occupational therapy students and clinical supervisors. A total of 40 questionnaires were returned: 17 from students and 23 from clinical supervisors. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics: preparation from the university for their placements; consistency across placement sites; instances of supervisors seeking feedback from students; and the burden associated with the placement-related workload for clinicians. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics DISCUSSION: Different perceptions around preparation from universities and consistency across placement sites relate to the existing roles of each group: students are more aware of university preparation and clinical supervisors are more aware of organisational inconsistencies in their respective usual work environments. The discrepancy in the perceived seeking of feedback from students has also been reported in student debriefing sessions. The burdens perceived by clinical supervisors appear to be influenced by a belief that clinical education is an additional duty rather than a core role. © 2016 John Wiley & Sons Ltd.

Jobs at Risk!? Effects of Automation of Jobs on Occupational Mobility

OpenAIRE

Sorgner, Alina

2017-01-01

The paper investigates the relationship between the risk of automation of jobs and individual-level occupational mobility using a representative German household survey. The results suggest that expected occupational changes such as losing a job and demotion at the current place of employment, among others, are likely to be driven by the high occupation-specific risk of automation. However, switches to self-employment are more likely to occur from occupations with low risk of automation.

We sought to master the clinical characteristics and prognosis of hard mental lung disease, improving this disease's diagnosis and treatment quality. We recruited two suspected patients with hard mental lung disease and collected their occupational history, examination results of occupational health, and past medical records. By virtue of laboratory tests, high Kv chest radiography, CT and HRCT of chest, fiberoptic bronchoscopy and ECG examination, diagnostic report was synthesized respectively by respiratory physicians and pathologist from three different agencies. Then the report was submitted to diagnosis organizations of occupational disease, and diagnostic conclusion of occupational disease was drawn after discussion by at least three diagnosticians of occupational disease. We found that both of the two suspected patients were exposed to dusts of hard metal, and length of exposure service ranged from 8 to 9 years. Clinical manifestations were dominated by dry cough, wheezing after activities, and pathological manifestation was characteristic giant cell interstitial pneumonia. The prognosis and outcome of the disease were different. According to exact occupational exposure history, clinical manifestations, combined with the results of high Kv chest radiography, CT of chest and pathological manifestation, it can be diagnosed with hard mental lung disease.

Participation and occupation in occupational therapy models of practice: A discussion of possibilities and challenges.

2017-11-01

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 assessment of occupational protection conditions in workplaces with high levels of exposure to natural radiation. Report from a technical committee meeting. Working material

International Nuclear Information System (INIS)

2002-01-01

Occupational exposure from natural radiation is, in the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2000 Report, estimated to contribute to more than 80 percent of the world-wide annual collective dose from occupational exposure, uranium mining excluded. The Agency's Radiation Safety Standards Series, the Requirements, and the Safety Guides (jointly sponsored by the Agency and the International Labour Office), address the control of occupational exposures from natural sources of radiation. In addition, some Safety Reports on specific issues are in the process of being finalized. Following upon recommendations to the Agency from its Member States to provide further guidance on the control of occupational exposure to natural radiation, a Technical Committee Meeting on Assessment of Occupational Radiation Protection Conditions in Workplaces with High Levels of Exposure to Natural Radiation was held in Vienna from 7 to 11 May 2001. The objective of the meeting was to produce an inventory of problem areas, make an assessment of the problem and propose a draft work plan for the Agency, This IAEA Working Material includes the report from the meeting, including the presentations made. Based on the recommendations made by the Technical Committee, a work plan is being initiated, implying that more attention will be paid to occupational exposure from natural radiation sources in the Occupational Radiation Protection programme

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.

To measure the prevalence of common mental disorder (CMD) by occupation in a representative sample of Great Britain and to identify occupations with increased and decreased risk of CMD. A cross-sectional interview-based survey was carried out including 5,497 working male and female respondents, 16-64 years from a stratified random survey of private households in Britain. Occupations were classified by the Standard Occupational Classification (SOC) into four groups: major, sub-major, minor and constituent unit groups. Common Mental Disorder was measured by the Revised Clinical Interview Schedule. Major SOC groups with higher prevalence of common mental disorder included clerical and secretarial, sales, and personal and protective services whereas craft and related, 'other' professional occupations and plant and machine operatives had lower prevalence compared to 13% overall prevalence in all adults. In sub-major SOC groups managers and administrators, teaching professionals, clerical and secretarial, 'other' sales and personal service occupations had higher prevalence whereas many professional and skilled occupations had lower prevalence. Specific SOC unit groups with higher prevalence included primary and secondary teachers, welfare community, youth workers, security staff, waiters, bar staff, nurse auxiliaries and care assistants. General managers in government and large organizations (OR=2.79, 95% CI 1.41-5.54), managers in transport and storing (OR=2.44, 95% CI 1.18-5.03), buyers and mobile sales persons (OR=2.48, 95% CI 1.09-5.60), sales occupations (NES) (OR=2.78, 95% CI 1.25-6.19) and clerks (NES) (OR=2.71, 95% CI 1.59-4.61) had increased risk of common mental disorder relative to specialist managers adjusting for social and financial factors and physical ill-health. Occupations with higher risk of common mental disorder may be typified by high levels of job demands, especially emotional demands and lack of job security. The reasons why occupations have low

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 Tibetan Plateau presents great challenges for human occupation: low oxygen, high ultraviolet radiation, harsh seasonal climate, low overall biological productivity. How and when early humans were able to cope physiologically, genetically, and behaviorally with these extremes is important for understanding the history of human adaptive flexibility. Our investigations of prehistoric human settlement on the northeast Tibetan Plateau focus on (a) establishing well-dated evidence for occupation of altitudes >3000 m, (b) the environmental context of high altitude adaptation, and (c) relations of hunting and pastoralism to lower-altitude agrarian systems. We observe two major prehistoric settlement patterns in the Qinghai Lake area. The earliest, ~15,000-7500 yr old, consists of small isolated firehearths with sparse associated stone tools and wild mammal remains (1). Numerous hearths often occur in the same localities, indicating repeated short-duration occupations by small hunting parties. A second pattern, ~9000-4000 yr old, was established during the Holocene climatic optimum. These sites represent prolonged seasonal residential occupation, containing dark anthropogenic midden, hearth and pit constructions, abundant stone tools, occasional ceramics, and abundant diverse faunal remains (including medium-large mammals but lacking domestic sheep/yak)(2). These Plateau-margin base camps allowed greater intensity of use of the high Plateau. Residential occupation was strongly influenced by nearby lower-altitude farming communities; development of the socioeconomic landscape along the Yellow River likely played at least as great a role in Plateau occupation patterns as did Holocene environmental changes. Holocene vegetation changes in the NE Tibetan Plateau have been attributed to climate (3) or anthropogenic modification (4). Our results document changes in shrub/tree presence from ~12,000-4000 BP, similar to pollen records, that likely reflect climate rather than

Full Text Available The size of farms has increased considerably during Finland's EU membership. The growth has meant big investments in the new production buildings. The buildings have been switched to big industrialhall- like constructions from small-scale ones which have contained own timber and own work contribution. The objective of the project financed by Farmers' Social Insurance Institution was to improve occupational safety on farm building construction and renovation sites by disseminating current safety practices and by developing ways of action which are better than the prevailing ones. The project consisted of a literature review, statistical analysis, as well as a farmer and designer interviews. In the statistical analysis the MATA occupational injuries insurance claims database on farmers’ claims during construction and renovation work for the years 2005 - 2008 was compared with the register of Federation of Accident Insurance Institutions on the construction workers' injuries. In comparing the reasons of the accidents a clear difference was found; poor scaffoldings and ladders are still the main culprits on farm accidents. Farmer interviews were used to assess occupational safety measures on the construction site, occurred injuries and their types, nearmiss situations and the underlying factors which have led to the injuries. Also construction safety deficiencies as well as the direct and indirect costs caused for instance because of the delay in completion of construction project were discussed. Designer interviews aimed to find out how occupational safety and health considerations are taken into account in farm building planning and counseling, and how this experience of the designers should be utilized in order to improve safety at the construction sites on farms. Farmers knew their obligations on occupational safety poorly. The situation was further worsened by the fact that on the site the supervisor tasks were only nominally executed. The

Occupational Experience, Mobility, and Wages

In this paper we present how occupational tenure relates to wage growth and occupational mobility in Danish data. We show that the Danish data produces qualitatively similar results as found in U.S. data with respect to an increase in average wages when experience in an occupation increases.

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.

Objective: To investigate occupational stress in migrant workers in an electronics manufacturing service enterprise and the association between occupational stress and early health effects, such as job burnout, depressive tendency, and insomnia. Methods: In August 2015, stratified random cluster sampling was used to select 1 097 migrant workers in an electronics manufacturing service enterprise. The Job Demand-Autonomy Questionnaire and effort-reward imbalance questionnaire were used to investigate occupational stress with the types of high workload and effort-reward imbalance, and Burnout Inventory, depression scale, and self-management sleep questionnaire were used to investigate the early health effects of occupational stress. Results: In these migrant workers, the detection rates of occupational stress with the types of high workload and effort-reward imbalance were 69.8%(766/1 097) and 11.9%(131/1 097). The multivariate logistic regression analysis showed that the workers who had occupational stress with the types of high workload and effort-reward imbalance had significantly higher risks of job burnout and depressive tendencies than those who did not have these two types of occupational stress ( P workers who had occupational stress with the type of effort-reward imbalance had a significantly higher ability to predict the risks of job burnout and depressive tendencies than those who had occupational stress with the type of high workload ( P health effects, such as job burnout, depressive tendency, and insomnia, in the migrant workers in this electronics manufacturing service enterprise. The workers who have occupational stress with the type of effort-reward imbalance have higher risks of job burnout and depressive tendencies than those who have occupational stress with the type of high workload.

This paper reviews the experience of the Workmen's Compensation Board of Ontario in identifying cases of cancer that could be attributed to occupational hazards. Workers' claims for compensation are allowed if there is reasonable medical evidence that their cancer was caused by exposure to risk factors associated with their occupation. Details of the types of cancers associated with specific carcinogens or fields of employment are discussed. About 50% of the cases were related to exposure in particular industrial operations that functioned for relatively brief periods. The number of deaths from cancer identified as being caused by occupational factors is compared with the total for cancer from all causes in Ontario during the period 1971 through 1975. Although all workers eligible for compensation may not have been identified, the data suggest that less than 1% is presently caused by occupational factors

Use of an appropriate teaching approach is a major concern for faculty members who are involved in occupational health and safety academic education. The challenge is to explore teaching tools to equip students with knowledge and skills to prepare them for their practices, in which they will encounter occupational health and safety issues in various occupational settings. The current study presents the design and implementation of a team project-based learning approach for undergraduate occupational health students to examine the appropriateness and perceptions of students and educators with regard to such a learning experience. Steps were taken to guide the educators and students through the learning process based on projects completed in teams. The research tools for collecting data were a questionnaire and semi-structured interviews with participants. The results illustrated that use of the proposed teaching approach as part of occupational health education may have the potential to motivate and enhance the active roles of educators and students in the learning process, and improve students' technical and social skills that are crucial for practice in the occupational health field. The study findings showed that project-based learning may provide a promising teaching strategy in the education and training of occupational health students. In addition, academic institutions should encourage educators to plan, introduce and evaluate the effectiveness of project-based learning.

Occupational noise and ischemic heart disease: A systematic review

Directory of Open Access Journals (Sweden)

Angel M Dzhambov

2016-01-01

Full Text Available Noise exposure might be a risk factor for ischemic heart disease (IHD. Unlike residential exposure, however, evidence for occupational noise is limited. Given that high-quality quantitative synthesis of existing data is highly warranted for occupational safety and policy, we aimed at conducting a systematic review and meta-analysis of the risks of IHD morbidity and mortality because of occupational noise exposure. We carried out a systematic search in MEDLINE, EMBASE, and on the Internet since April 2, 2015, in English, Spanish, Russian, and Bulgarian. A quality-scoring checklist was developed a priori to assess different sources of methodological bias. A qualitative data synthesis was performed. Conservative assumptions were applied when appropriate. A meta-analysis was not feasible because of unresolvable methodological discrepancies between the studies. On the basis of five studies, there was some evidence to suggest higher risk of IHD among workers exposed to objectively assessed noise >75–80 dB for <20 years (supported by one high, one moderate, and one low quality study, opposed by one high and one moderate quality study. Three moderate and two low quality studies out of six found self-rated exposure to be associated with higher risk of IHD, and only one moderate quality study found no effect. Out of four studies, a higher mortality risk was suggested by one moderate quality study relying on self-rated exposure and one of high-quality study using objective exposure. Sensitivity analyses showed that at higher exposures and in some vulnerable subgroups, such as women, the adverse effects were considerably stronger. Despite methodological discrepancies and limitations of the included studies, occupational noise appeared to be a risk factor for IHD morbidity. Results suggested higher risk for IHD mortality only among vulnerable subgroups. Workers exposed to high occupational noise should be considered at higher overall risk of IHD.

Occupation embedded in a real life: interweaving occupational science and occupational therapy. 1993 Eleanor Clarke Slagle Lecture.

Science.gov (United States)

Clark, F

1993-12-01

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.

To analyze the status of occupational stress in different types of train drivers. By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual factors, occupational stress factors, stress response factors and stress mitigating factors. The occupational stress factors, stress response factors and mitigating factors were measured by the revised effort-reward imbalance (ERI) model questionnaires and occupational stress measurement scale. By using the method of covariance analysized the difference of occupational stress factors of all types train drivers, the method of Stepwise regression was used to analyze the effection (R(2)) of occupational stress factors and stress mitigating factors on stress response factors. Covariance analysis as covariates in age, education level, length of service and marital status showed that the scores of ERI (1.58 ± 0.05), extrinsic effort (19.88 ± 0.44), rewards (23.43 ± 0.43), intrinsic effort (17.86 ± 0.36), physical environment (5.70 ± 0.22), social support (30.51 ± 0.88) and daily tension (10.27 ± 0.38 ) of high speed rail drivers were higher than other drivers (F values were 6.06, 11.32, 7.05, 13.25, 5.20, 9.48 and 6.14 respectively, P occupational stress factors and mitigating factors to depressive symptoms of train drivers was high speed rail drivers (R(2) = 0.64), passenger train drivers (R(2) = 0.44), passenger shunting train drivers (R(2) = 0.39), freight trains drivers (R(2) = 0.38); job satisfaction of train drivers was high speed rail drivers (R(2) = 0.68), passenger train drivers (R(2) = 0.62), freight trains drivers (R(2) = 0.43), passenger shunting train drivers(R(2) = 0.38); to daily tension of train drivers was high speed rail drivers (R(2) = 0.54), passenger train drivers (R(2) = 0

Full Text Available Many workers worldwide experience fatality and disability caused by occupational injuries. This study examined the relationship between noise exposure and occupational injuries at factories in Korea. A total of 1790 factories located in northern Gyeonggi Province, Korea was evaluated. The time-weighted average levels of dust and noise exposure were taken from Workplace Exposure Assessment data. Apart occupational injuries, sports events, traffic accidents, and other accidents occurring outside workplaces were excluded. The incidences of occupational injury in each factory were calculated by data from the Korea Workers′ Compensation and Welfare Services. Workplaces were classified according to the incidence of any occupational injuries (incident or nonincident workplaces, respectively. Workplace dust exposure was classified as 90 dB. Workplaces with high noise exposure were significantly associated with being incident workplaces, whereas workplaces with high dust exposure were not. The odds ratios (95% confidence intervals derived from a logistic regression model were 1.68 (1.27-2.24 and 3.42 (2.26-5.17 at 80-89 dB and ≥90 dB versus <80 dB. These associations remained significant when in a separate analysis according to high or low dust exposure level. Noise exposure increases the risk of occupational injury in the workplace. Furthermore, the risk of occupational injury increases with noise exposure level in a dose-response relationship. Therefore, strategies for reducing noise exposure level are required to decrease the risk of occupational injury.

Margaret*, a 56 year-old Caucasian Stage III breast cancer survivor, participated in a 5 week occupational therapy pilot program, called Take Action. This program was designed for breast cancer survivors who self-reported changes in cognitive function following completion of chemotherapy. The goals of the program were to improve participants' knowledge and use of strategies to enhance occupational performance and to improve satisfaction and performance of meaningful daily activities or occupations. Through a client-centered and evidence-based approach, this case study highlights the importance of incorporating the survivors' sense of self into an occupation-based intervention. Occupational therapists play an important role in facilitating exploration of sense of self in the survivorship phase of care to support occupational performance in self care, productivity, work, leisure and social participation. This case study highlights the important work of redefining oneself in the survivorship phase of care. (*denotes name change).

2016-12-02

Workers in various industries and occupations are at risk for work-related asthma* (1). Data from the 2006-2007 adult Behavioral Risk Factor Surveillance System (BRFSS) Asthma Call-back Survey (ACBS), an in-depth asthma survey conducted with respondents who report an asthma diagnosis, from 33 states indicated that up to 48% of adult current asthma might be related to work and could therefore potentially be prevented (2). Identification of the industries and occupations with increased prevalence of asthma might inform work-related asthma intervention and prevention efforts. To assess the industry-specific and occupation-specific proportions of adults with current asthma by state, CDC analyzed data from the 2013 BRFSS industry and occupation module, collected from 21 states for participants aged ≥18 years who, at the time of the survey interview, were employed or had been out of work for industry and occupation were observed. By state, current asthma prevalence was highest among workers in the information industry (18.0%) in Massachusetts and in health care support occupations (21.5%) in Michigan. Analysis of BRFSS industry and occupation and optional asthma modules can be used to identify industries and occupations to assess for asthma among workers, identify workplace exposures, and guide the design and evaluation of effective work-related asthma prevention and education programs (1).

2009-08-01

A previous study reported that fathers of children with autism spectrum disorders (ASD) were more likely to work as engineers, requiring "systemizing skills," and suggesting a distinct phenotype, but alternatively this may have been related to selection biases. We conducted a population-based study to explore whether fathers, or mothers, of children with ASD are over-represented in fields requiring highly technical skills. Subjects included 284 children with ASD and 659 gender-matched controls, born in 1994 in the San Francisco Bay Area. Parental occupation and industry were abstracted verbatim from birth certificates. Engineering, computer programming, and science were examined as highly technical occupations. To limit bias by parental socio-economic status, we selected a referent group of occupations that seemed professionally similar but of a less technical nature. Odds ratios (ORs) and 95% confidence intervals (CI) were calculated by logistic regression, adjusting for parental age, education, and child race. Mothers of cases were somewhat more likely to work in hi-tech occupations (6.7%) than mothers of controls (4.0%, P=0.07), but little difference was observed among fathers, nor for engineering separately. Compared to parents in other "white collar" occupations, the adjusted OR for highly technical occupations among mothers was 2.5 (95% CI: 1.2-5.3) and among fathers was 1.3 (95% CI: 0.79-2.1), with no evidence of a joint effect observed. Our results regarding maternal occupation in technical fields being associated with ASD in offspring suggest further study to distinguish parental occupation as a phenotypic marker of genetic loading vs. other social or exposure factors.

Occupational allergy as a challenge to developing countries.

Science.gov (United States)

Rydzynski, Konrad; Palczynski, Cezary

2004-05-20

A steady increase in the incidence of allergic diseases can be observed since 1950s. For such atopic diseases as bronchial asthma, pollinosis or atopic dermatitis, a significantly increased morbidity rate in the general population has been found. Strikingly enough, the highest prevalence of asthma and allergy was recorded in highly developed countries. It can thus be assumed that the high rate of asthma may be an attribute of the post-industrial societies. The prevalence of occupational allergies is thought to be in direct proportion to the rate with which allergies occur in the general population. In view of the changing environment and lifestyles in the developing countries, their communities are expected to be faced with similar negative epidemiological effects concerning allergies. To counteract the spreading of negative health effects, the following measures need to be undertaken: 1. Limitation of exposure to strong allergens. 2. Modification of the training curriculum for medical personnel and of health service infrastructure, according to new tasks and challenges. 3. Considering a possibility of introducing a system of surveillance over occupational allergies and asthma, like the Surveillance of Work-related and Occupational Respiratory Disease (SWORD) system implemented in UK. This system ensures effective cooperation between specialists in preventive medicine, occupational hygiene services and research workers dealing with occupational health that enables prompt response to emerging hazards.

Occupational therapy in Australian acute hospitals: A modified practice.

Britton, Lauren; Rosenwax, Lorna; McNamara, Beverley

2016-08-01

Ongoing changes to health-care funding Australia wide continue to influence how occupational therapists practise in acute hospitals. This study describes the practice challenges experienced by Western Australian acute care occupational therapists. Then, it explores if and how acute care occupational therapists are modifying their practice in response to these practice changes. This study used a qualitative grounded theory approach. Semi-structured interviews were completed with 13 purposively selected acute care occupational therapists from four Western Australian metropolitan hospitals. Data were analysed using a constant comparative method to provide detailed descriptions of acute care occupational therapy practice and to generate theory. Five conceptual categories were developed. The first two addressed practice challenges: pragmatic organisational influences on client care and establishing a professional identity within the multidisciplinary team. Three categories related to therapist responses are as follows: becoming the client advocate, being the facilitator and applying clinical reasoning. Finally, modified practice was identified as the core category which explains the process whereby acute care occupational therapists are ensuring they remain relevant and authentic in the acute care context. Western Australian acute care occupational therapists are practising in a highly complex health context that presents many challenges. They are responding by using a modified form of practice that ensures occupational therapy skills remain relevant within the narrow confines of this health setting. © 2016 Occupational Therapy Australia.

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.

PREVENTION OF OCCUPATIONAL ACCIDENTS

Directory of Open Access Journals (Sweden)

Jovica Jovanovic

2004-01-01

Full Text Available Medical services, physicians and nurses play an essential role in the plant safety program through primary treatment of injured workers and by helping to identify workplace hazards. The physician and nurse should participate in the worksite investigations to identify specific hazard or stresses potentially causing the occupational accidents and injuries and in planning the subsequent hazard control program. Physicians and nurses must work closely and cooperatively with supervisors to ensure the prompt reporting and treatment of all work related health and safety problems. Occupational accidents, work related injuries and fatalities result from multiple causes, affect different segments of the working population, and occur in a myriad of occupations and industrial settings. Multiple factors and risks contribute to traumatic injuries, such as hazardous exposures, workplace and process design, work organization and environment, economics, and other social factors. With such a diversity of theories, it will not be difficult to understand that there does not exist one single theory that is considered right or correct and is universally accepted. These theories are nonetheless necessary, but not sufficient, for developing a frame of reference for understanding accident occurrences. Prevention strategies are also varied, and multiple strategies may be applicable to many settings, including engineering controls, protective equipment and technologies, management commitment to and investment in safety, regulatory controls, and education and training. Research needs are thus broad, and the development and application of interventions involve many disciplines and organizations.

2012-01-01

There was considerable evidence that a subject’s psychological status may influence respiratory sensations and that some subjects may experience respiratory symptoms regardless of the presence of a respiratory disease. The objective of this study was to determine the association between occupational stress and respiratory symptoms among lecturers. This cross sectional study was conducted in Universiti Putra Malaysia, involved 61 lecturers from various faculties. Job Content Questionnaire (JCQ) and questionnaires based on American Thoracic Society were used to collect the data on socio-demography, stress level and respiratory symptoms. High level of occupational stress (high strain) was determined among 16 of the respondents (26.2%). Breathlessness was the common symptom experienced by the respondents. Female lecturers were significantly experienced high stress level compared to male (p=0.035). They were also significantly having more breathlessness symptom compared to male lecturer (p=0.011). Study highlighted in study population, gender plays a significant role that influenced level of occupational stress and also gender has role in resulting occupational stress level and respiratory symptoms. There was no significant association between occupational stress and respiratory symptoms. It can be concluded that this group of lecturers of Universiti Putra Malaysia did not experienced high occupational stress level. Occupational stress level was not statistically significantly associated with all respiratory symptoms being studied. PMID:23121752

Occupational-attributable chronic obstructive pulmonary disease (COPD) presents a substantial health challenge. Focusing on spirometric criteria for airflow obstruction, this review of occupational COPD includes both population-wide and industry-specific exposures. We used PubMed and Embase to identify relevant original epidemiological peer-reviewed articles, supplemented with citations identified from references in key review articles. This yielded 4528 citations. Articles were excluded for lack of lung function measurement, insufficient occupational exposure classification, lack of either external or internal referents, non-accounting of age or smoking effect, or major analytic inadequacies preventing interpretation of findings. A structured data extraction sheet was used for the remaining 147 articles. Final inclusion was based on a positive qualitative Scottish Intercollegiate Guidelines Network (SIGN) score (≥2+) for study quality, yielding 25 population-wide and 34 industry/occupation-specific studies, 15 on inorganic and 19 on organic dust exposure, respectively. There was a consistent and predominantly significant association between occupational exposures and COPD in 22 of 25 population-based studies, 12 of 15 studies with an inorganic/mineral dust exposure, and 17 of 19 studies on organic exposure, even though the studies varied in design, populations, and the use of measures of exposure and outcome. A nearly uniform pattern of a dose-response relationship between various exposures and COPD was found, adding to the evidence that occupational exposures from vapors, gas, dust, and fumes are risk factors for COPD. There is strong and consistent evidence to support a causal association between multiple categories of occupational exposure and COPD, both within and across industry groups.

Occupational skin cancers

Skin cancer due to occupation is more common than is generally recognized, although it is difficult to obtain an accurate estimate of its prevalence. Over the past two centuries, occupational skin cancers have particularly been due to industrial exposure of men (it seems more so than women) to chemical carcinogens such as polycyclic hydrocarbons (e.g. from coal tar products) or to arsenic. Industrial processes have improved in most Western countries to limit this type of exposure, but those with outdoor occupations are still exposed to solar ultraviolet irradiation without this being widely recognized as an industrial hazard. Ionizing radiation such as X-rays can also cause skin cancer. Occupational skin cancers often resemble skin tumours found in non-occupational subjects, e.g. basal cell carcinoma, squamous cell carcinoma and malignant melanoma, but some pre-malignant lesions can be more specific and point to an occupational origin, e.g. tar keratoses or arsenical keratoses. An uncommon but well-recognized cause of occupational skin cancer is that which results from scar formation following an industrial burn. In the future it will be necessary to focus on preventative measures, e.g. for outdoor workers, the need to cover up in the sun and use sun protective creams and a campaign for earlier recognition of skin cancers, which are usually curable if treated in their early stages.

Occupational employment trends in selected nuclear industry segments in the United States of America

The United States of America's nuclear energy industry expanded rapidly between 1968 and 1977, with total employment increasing by approximately 60%. Between 1973 and 1977 employment grew at a rate of 6.8% per year. The nuclear industry appears to have reached a mature status with the primary focus on commercial activities. The relative number of workers involved in research and development activities, outside of contract research facilities, has declined considerably since 1968 but appears to have stabilized. The industry labour force still has a relatively high proportion (43%) of scientific, engineering and technical workers. The occupational employment composition appears to have stabilized in the various nuclear segments indicating the emergence of longer run occupational distribution patterns. Employment expanded rapidly between 1968 and 1977 in most nuclear segments, with the exception of the research and development segment, where employment decreased by one-third. The present uncertainties concerning nuclear power development could have substantial impacts on the nuclear-related scientific, engineering, and technical labour force if a sizeable contraction occurs in reactor design and manufacturing and in design of nuclear facilities.

Full Text Available Due to the densely population and mobility characteristics of the crowd, generally accidents happened in assembly occupancies will trigger a chain reaction, and then bring heavy casualties and property loss, and result disastrous consequences. In the context of safety regulation resources limited, building risk classification system of assembly occupancies is important for "scientific predicting, and hierarchical controlling” In this paper, a software with a graphical user interface is designed using MATLAB GUI to analyze and calculate risks of stampede accident caused by gathered crowds in the video. A velocity extraction method based on cross-correlation algorithm is adopted, and the risk characteristic parameters such as velocity variance is also applied. In this way, real-time analysis and early-warning for risks of stampede accident in time and space can be achieved. Also, the algorithm is applied to the surveillance video of the stampede in Shanghai and its feasibility is proved. Empirical research shows that, the assembly occupancies risk rating model built in this paper has good effectiveness, simplicity and practicability, applies to the government safety regulation and organization safety management, and can improve the safety situation of assembly occupancies effectively.

Also, using methodology of the International Labor Organizationcorrelcation between the amount of accident fatalities and general number of accidents in Ukraine and EU countries (Austria, GreatBritain, Germany, Denmark, Norway, Poland, Hungry, Finland, France is defined. It is shown that in spite of the positive dynamicsof decreasing amount of occupational injuries, the number of occupational diseases in Ukraine always increases. The comparativeanalysis of the ratio of the number of accident fatalities to the total number of registered accidents showed that, on average, Ukraineexceeds the EU countries by this indicator by 100 times.It is noted, that such negative indicators (in particular, increasing amount of occupational diseases, may occure because ofimperfect methodology for identifying the risks of professional dangerous.Also, it is ascertained that basing on the existed methodology, the identefication process of occupational dangerous isquite subjective, which reduces objectivity of conducting quantitative assessment.

2012-04-01

Exposure to ionizing radiation occurs in many occupations. Workers can be exposed to both natural and artificial sources of radiation. Any exposure to ionizing radiation incurs some risk, either to the individual or to the individual's progeny. This dissertation investigated the radiation risk due to occupational exposure in industrial radiography. Analysis of the reported risk estimates to occupational exposure contained in the UNSCEAR report of 2008 in industrial radiography practice was done. The causes of accidents in industrial radiography include: Lack of or inadequate regulatory control, inadequate training, failure to follow operational procedures, human error, equipment malfunction or defect, inadequate maintenance and wilful violation have been identified as primary causes of accidents. To minimise radiation risks in industrial radiography exposure devices and facilities should be designed such that there is intrinsic safety and operational safety ensured by establishing a quality assurance programme, safety culture fostered and maintained among all workers, industrial radiography is performed in compliance with approved local rules, workers engaged have appropriate qualifications and training, available safe operational procedures are followed, a means is provided for detecting incidents and accidents and an analysis of the causes and lessons learned.

Giesbrecht, Ed

2013-08-01

Theoretical models provide a framework for describing practice and integrating evidence into systematic research. There are few models that relate specifically to the provision of assistive technology in occupational therapy practice. The Human Activity Assistive Technology model is an enduring example that has continued to develop by integrating a social model of disability, concepts from occupational therapy theory and principles of assistive technology adoption and abandonment. This study first describes the core concepts of the Human Activity Assistive Technology model and reviews its development over three successive published versions. A review of the research literature reflects application of the model to clinical practice, study design, outcome measure selection and interpretation of results, particularly among occupational therapists. An evaluative framework is used to critique the adequacy of the Human Activity Assistive Technology model for practice and research, exploring attributes of clarity, simplicity, generality, accessibility and importance. Finally, recommendations are proposed for continued development of the model and research applications. Most of the existing research literature employs the Human Activity Assistive Technology model for background and study design; there is emerging evidence to support the core concepts as predictive factors. Although the concepts are generally simple, clear and applicable to occupational therapy practice and research, evolving terminology and outcomes become more complex with the conflation of integrated theories. The development of the Human Activity Assistive Technology model offers enhanced access and application for occupational therapists, but poses challenges to clarity among concepts. Suggestions are made for further development and applications of the model. © 2013 Occupational Therapy Australia.

Management system of occupational diseases in Korea: statistics, report and monitoring system.

Rhee, Kyung Yong; Choe, Seong Weon

2010-12-01

The management system of occupational diseases in Korea can be assessed from the perspective of a surveillance system. Workers' compensation insurance reports are used to produce official statistics on occupational diseases in Korea. National working conditions surveys are used to monitor the magnitude of work-related symptoms and signs in the labor force. A health examination program was introduced to detect occupational diseases through both selective and mass screening programs. The Working Environment Measurement Institution assesses workers' exposure to hazards in the workplace. Government regulates that the employer should do health examinations and working conditions measurement through contracted private agencies and following the Occupational Safety and Health Act. It is hoped that these institutions may be able to effectively detect and monitor occupational diseases and hazards in the workplace. In view of this, the occupational management system in Korea is well designed, except for the national survey system. In the future, national surveys for detection of hazards and ill-health outcomes in workers should be developed. The existing surveillance system for occupational disease can be improved by providing more refined information through statistical analysis of surveillance data.

Identification and Hierarchy of Main Electronic Health Record Components in Occupational Medicine

Full Text Available Starting from the legal requirements relating to structuring of medical records in occupational medicine and international requirements regarding the certification of electronic health records we have focused on structuring and then evaluating an EHR model in occupational medicine that integrates the main functions and certification criteria required by the European and US certification bodies. The application we designed, called Medmun, structured for use in occupational medicine practices based on the model of medical file provided by the Romanian legislation, integrates both necessary components of occupational medicine practice for administration of characteristic information related to socio-economic unit, work place, health surveillance as well as components of specific EHR functionality. The application has been submitted for free evaluation by specialist physicians of five counties over a period of nine months and subsequently assessed using a questionnaire on the usefulness of specific functional components in the EHR occupational medicine practice. The model was positively evaluated after experimental employment by occupational health practitioners. They consider that absence of legislative support for EHR implementation in medical practice is the main obstacle to the use of such applications in occupational medicine practice.

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.

Although routine workers' health examinations are extensively performed worldwide with important resource allocation, few studies have analyzed their quality. The objective of this study has been to analyze the medical practice of workers' health examinations in Catalonia (Spain) in terms of its occupational preventive aim. A cross-sectional study was carried out by means of an online survey addressed to occupational physicians who were members of the Catalan Society of Safety and Occupational Medicine. The questionnaire included factual questions on how they performed health examinations in their usual practice. The bivariate analysis of the answers was performed by type of occupational health service (external/internal). The response rate was 57.9% (N = 168), representing 40.3% of the reference population. A high percentage of occupational physicians had important limitations in their current medical practice, including availability of clinical and exposure information, job-specificity of tests, and early detection and appropriate management of suspected occupational diseases. The situation in external occupational health services - that covered the great majority of Catalan employees - was worse remarkably in regard to knowledge of occupational and nonoccupational sickness absence data, participation in the investigation of occupational injuries and diseases, and accessibility for workers to the occupational health service. This study raises serious concerns about the occupational preventive usefulness of these health examinations, and subsequently about our health surveillance system, based primarily on them. Professionals alongside health and safety institutions and stakeholders should promote the rationalization of this system, following the technical criteria of need, relevance, scientific validity and effectiveness, whilst ensuring that its ultimate goal of improving the health and safety of workers in relation to work is fulfilled.

Salamander occupancy in headwater stream networks

1. Stream ecosystems exhibit a highly consistent dendritic geometry in which linear habitat units intersect to create a hierarchical network of connected branches. 2. Ecological and life history traits of species living in streams, such as the potential for overland movement, may interact with this architecture to shape patterns of occupancy and response to disturbance. Specifically, large-scale habitat alteration that fragments stream networks and reduces connectivity may reduce the probability a stream is occupied by sensitive species, such as stream salamanders. 3. We collected habitat occupancy data on four species of stream salamanders in first-order (i.e. headwater) streams in undeveloped and urbanised regions of the eastern U.S.A. We then used an information-theoretic approach to test alternative models of salamander occupancy based on a priori predictions of the effects of network configuration, region and salamander life history. 4. Across all four species, we found that streams connected to other first-order streams had higher occupancy than those flowing directly into larger streams and rivers. For three of the four species, occupancy was lower in the urbanised region than in the undeveloped region. 5. These results demonstrate that the spatial configuration of stream networks within protected areas affects the occurrences of stream salamander species. We strongly encourage preservation of network connections between first-order streams in conservation planning and management decisions that may affect stream species.

Background Identification of risk factors for lower extremity (LE) injury in sport and military/first-responder occupations is required to inform injury prevention strategies. Objective To determine if poor movement quality is associated with LE injury in sport and military/first-responder occupations. Material and methods Five electronic databases were systematically searched. Studies selected included: original data; analytic design; movement quality outcome (qualitative rating of functional compensation, asymmetry, impairment or efficiency of movement control); LE injury sustained with sport or military/first-responder occupation. The PRISMA guidelines were followed. Two independent authors assessed the quality [Downs and Black (DB) criteria] and level of evidence (Oxford Centre of Evidence-Based Medicine model). Results Of 4361 potential studies, 17 were included. The majority were low quality cohort studies (level 4 evidence). Median DB score was 11/33 (range 3–15). Heterogeneity in methodology and injury definition precluded meta-analyses. The Functional Movement Screen was the most common outcome investigated (15/17 studies). Four studies considered interrelationships between risk factors, seven reported diagnostic accuracy and none tested an intervention program targeting individuals identified as high-risk. There is inconsistent evidence that poor movement quality is associated with increased risk of LE injury in sport and military/first-responder occupations. Conclusions Future research should focus on high quality cohort studies to identify the most relevant movement quality outcomes for predicting injury risk followed by developing and evaluating pre-participation screening and LE injury prevention programs through high quality randomized controlled trials targeting individuals at greater risk of injury based upon screening tests with validated test properties.

2014-12-01

Full Text Available There are many iconic high rise buildings in Hong Kong, for example, International Commercial Centre, International Financial Centre, etc. Fire safety issue in high rise buildings has been raised by local fire professionals in terms of occupant evacuation, means of fire-fighting by fire fighters, sprinkler systems to automatically put off fires in buildings, etc. Fire risk becomes an important issue in building fire safety because it relates to life safety of building occupants where they live and work in high rise buildings in Hong Kong. The aim of this research is to identify the fire risk for different types of high rise buildings in Hong Kong and to optimise the fire prevention management for those high rise buildings with higher level of fire risk and to validate the model and also to carry out the study of the conflict between the current fire safety building code and the current trend of green building design. Survey via the 7-point scale questionnaire was conducted through 50 participants and their responses were received and analysed via the statistical tool SPSS software computer program. A number of statistical methods of testing for significantly difference in samples were adopted to carry out the analysis of the data received. When the statistical analysis was completed, the results of the data analysis were validated by two Fire Safety Experts in this area of specialisation and also by quantitative fire risk analysis.

Does occupational therapy play a role for communication in children with autism spectrum disorders?

2014-12-01

This study investigates occupational therapy for early communication in children with autism spectrum disorders (ASD). The research explored the role of occupational therapists in supporting children with ASD to become better communicators by considering their inter-professional collaboration with speech-language pathologists. Convenience samples of 21 clinical occupational therapists and speech-language pathologists were recruited to participate in semi-structured audio-recorded focus groups, using a qualitative design. Distinct views included a child-centred focus from speech-language pathologists, whereas occupational therapists spoke of the child through societal viewpoints, which later pointed to occupational therapists' proficiency in enabling skill generalization in ASD. An equal partnership was consistently reported between these clinicians, who identified the same objectives, shared strategies, joint treatments, and ongoing collaboration as the four main facilitators to inter-professional collaboration when treating children with ASD. Three unique roles of occupational therapy comprised developing non-verbal and verbal communication pre-requisites, adapting the setting, educating-partnering-advocating for the child, and providing occupation-based intervention. These three themes meshed with the discipline-specific occupational therapy domains represented in the Person-Environment-Occupation framework. When working in inter-professional collaboration, speech-language pathologists and occupational therapists agree that occupational therapy is indispensable to early intervention in enabling communication in ASD.

Physical Workload and Work Capacity across Occupational Groups.

Full Text Available This study aimed to determine physical performance criteria of different occupational groups by investigating physical activity and energy expenditure in healthy Swiss employees in real-life workplaces on workdays and non-working days in relation to their aerobic capacity (VO2max. In this cross-sectional study, 337 healthy and full-time employed adults were recruited. Participants were classified (nine categories according to the International Standard Classification of Occupations 1988 and merged into three groups with low-, moderate- and high-intensity occupational activity. Daily steps, energy expenditure, metabolic equivalents and activity at different intensities were measured using the SenseWear Mini armband on seven consecutive days (23 hours/day. VO2max was determined by the 20-meter shuttle run test. Data of 303 subjects were considered for analysis (63% male, mean age: 33 yrs, SD 12, 101 from the low-, 102 from the moderate- and 100 from the high-intensity group. At work, the high-intensity group showed higher energy expenditure, metabolic equivalents, steps and activity at all intensities than the other groups (p<0.001. There were no significant differences in physical activity between the occupational groups on non-working days. VO2max did not differ across groups when stratified for gender. The upper workload limit was 21%, 29% and 44% of VO2max in the low-, moderate- and high-intensity group, respectively. Men had a lower limit than women due to their higher VO2max (26% vs. 37%, when all groups were combined. While this study did confirm that the average workload limit is one third of VO2max, it showed that the average is misrepresenting the actual physical work demands of specific occupational groups, and that it does not account for gender-related differences in relative workload. Therefore, clinical practice needs to consider these differences with regard to a safe return to work, particularly for the high-intensity group.

Occupational and leisure-time physical activity are considered to provide similar health benefits. The authors tested this hypothesis. A representative sample of Danish employees (n=7144, 52% females) reported levels of occupational and leisure-time physical activity in 2005. Long-term sickness absence (LTSA) spells of ≥3 consecutive weeks were retrieved from a social-transfer payment register from 2005 to 2007. 341 men and 620 females experienced a spell of LTSA during the period. Cox analyses adjusted for age, gender, smoking, alcohol, body mass index, chronic disease, social support from immediate superior, emotional demands, social class and occupational or leisure-time physical activity showed a decreased risk for LTSA among workers with moderate (HR 0.85, CI 0.72 to 1.01) and high (HR 0.77, CI 0.62 to 0.95) leisure-time physical activity in reference to those with low leisure-time physical activity. In contrast, an increased risk for LTSA was shown among workers with moderate (HR 1.59, CI 1.35 to 1.88) and high (HR 1.84, CI 1.55 to 2.18) occupational physical activity referencing those with low occupational physical activity. The hypothesis was rejected. In a dose-response manner, occupational physical activity increased the risk for LTSA, while leisure-time physical activity decreased the risk for LTSA. The findings indicate opposing effects of occupational and leisure-time physical activity on global health.

Aerodynamic design on high-speed trains

2016-04-01

Compared with the traditional train, the operational speed of the high-speed train has largely improved, and the dynamic environment of the train has changed from one of mechanical domination to one of aerodynamic domination. The aerodynamic problem has become the key technological challenge of high-speed trains and significantly affects the economy, environment, safety, and comfort. In this paper, the relationships among the aerodynamic design principle, aerodynamic performance indexes, and design variables are first studied, and the research methods of train aerodynamics are proposed, including numerical simulation, a reduced-scale test, and a full-scale test. Technological schemes of train aerodynamics involve the optimization design of the streamlined head and the smooth design of the body surface. Optimization design of the streamlined head includes conception design, project design, numerical simulation, and a reduced-scale test. Smooth design of the body surface is mainly used for the key parts, such as electric-current collecting system, wheel truck compartment, and windshield. The aerodynamic design method established in this paper has been successfully applied to various high-speed trains (CRH380A, CRH380AM, CRH6, CRH2G, and the Standard electric multiple unit (EMU)) that have met expected design objectives. The research results can provide an effective guideline for the aerodynamic design of high-speed trains.
