    According to the Brazilian National Database there are about 300 Nuclear Medicine Services (NMS) in Brazil, 44 of them located in the State of Rio de Janeiro (RJ). Individual dose measurements are an important input for the evaluation of occupational exposure in order to demonstrate the effectiveness of radioprotection implementation and to keep individual doses as low as possible. In Brazil, most nuclear medicine (NM) staff is routinely monitored for external dose. The internal committed dose is estimated only in abnormal conditions. This paper makes a statistics analysis of all the RJ NMS annual external occupational doses in year 2005. A study of the evolution of monthly external individual doses higher than 4.00 mSv from 2004 to 2008 is also presented. The number of registered thorax monthly dose higher than 4.0 mSv is increasing, as its value. In this period the highest dose measured reaches 56.9 mSv, in one month, in 2008. About 50% of the annual doses are smaller than the monthly record level of 0.20 mSv. In 2005, around 100 professionals of RJ NMS received annual doses higher than 4.0 mSv, considering only external doses, but no one receives doses higher than 20.0 mSv. Extremities dosimeters are used by about 15% of the staff. In some cases, these doses are more than 10 times higher than the dose in thorax. This study shows the importance to improve radiation protection procedures in NM. (author)

    Exposure to external radiation occurs in many occupations. Any exposure to ionizing radiation has the tendency to change the biochemical make-up of the human body which may result in biological health effects of ionizing radiation. This study reviews the monitoring and assessment of external radiation doses in industrial radiography using thermoluminescence and direct reading dosimeters. Poor handling procedures such as inadequate engineering control of equipment, safety culture, management, and inadequate assessment and monitoring of doses are the causes of most of the reported cases of exposure to external radiation in industrial radiography. Occupational exposure data in industrial radiography from UNSCEAR report 2008 was discussed and recommendations were made to regulatory authorities, operating organizations and radiographers. (au)

    In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

  5. Report on external occupational dosimetry in Canada

    1995-12-01

    In light of the new recommendations of the ICRP in Report 60 on dose quantities and dose limits, this working group was set up to examine the implications for external dosimetry in Canada. The operational quantities proposed by the ICRU are discussed in detail with regard to their applicability in Canada. The current occupational dosimetry services available in Canada are described as well as the several performance intercomparisons that have been carried out within the country as well as internationally. Recommendations are given with respect to standards for dosimetry, including accuracy and precision. More practical advice is given on the choice of dosimeter to use for external dosimetry, frequency of monitoring, and who should be monitored. Specific advice is given on the monitoring of pregnant workers and problem of non-uniform irradiation. Accident and emergency dosimetry are dealt with briefly. Suggestions are given regarding record keeping both for employers and for the national dose registry. 48 refs., 6 tabs., 1 fig

    Brazil, a continental country, with actually more than 150,000 workers under individual monitoring for ionizing radiation, has implemented in 1987 a centralized system for storage of external occupational dose. This database has been improved over the years and is now a web-based information system called Brazilian External Occupational Dose Management Database System - GDOSE. This paper presents an overview of the Brazilian external occupational dose over the years. The estimated annual average effective dose shows a decrease from 2.4 mSv in 1987 to about 0.6 mSv, having been a marked reduction from 1987 to 1990. Analyzing by type of controlled practice, one sees that the medical and dental radiology is the area with the largest number of users of individual monitors (70%); followed by education practices (8%) and the industrial radiography (7%). Additionally to photon whole body monitoring; neutron monitors are used in maintenance (36%), reactor (30%) and education (27%); and extremity monitors, in education (27%), nuclear medicine (22%) and radiology (19%). In terms of collective dose, the highest values are also found in conventional radiology, but the highest average dose values are those of interventional radiology. Nuclear medicine, R and D and radiotherapy also have average annual effective dose higher than 1 mSv. However, there is some very high dose values registered in GDOSE that give false information. This should be better analyzed in the future. Annual doses above 500 are certainly not realistic. (author)

    Perspectives that individualize occupation are poorly aligned with socially responsive and transformative occupation-focused research, education, and practice. Their predominant use in occupational therapy risks the perpetuation, rather than resolution, of occupational inequities. In this paper, we problematize taken-for-granted individualistic analyses of occupation and illustrate how critical theoretical perspectives can reveal the ways in which structural factors beyond an individual's immediate control and environment shape occupational possibilities and occupational engagement. Using a critically reflexive approach, we draw on three distinct qualitative research studies to examine the potential of critical theorizing for expanding beyond a reliance on individualistic analyses and practices. Our studies highlight the importance of addressing the socio-historical and political contexts of occupation and demonstrate the contribution of critical perspectives to socially responsive occupational therapy. In expanding beyond individualistic analyses of occupation, critical perspectives advance research and practices towards addressing socio-political mediators of occupational engagement and equity.

    In 1976 a total of 36,794 occupationally exposed persons were monitored by the National Board of Nuclear Safety and Radiation Protection, using film badges. The monthly over-exposures (more than 4 mGy) totalled 415. In 11 cases the monthly exposure exceeded 30 mGy and 6 annual exposure values were in the range of 50 to 120 mGy. An attempt has been made to assess the annual collective and annual per caput doses for the exposed population as a whole and some subgroups without completely summing up the individual exposure data.

    Individual monitoring of workers exposed to external radiations must fulfill technical, regulatory and organizational requirements. The external dosimetry should be adapted to the workplace. The relevant dosimetric techniques have to be chosen upon the workplace study that conditions both the categorization of exposed workers and classification of areas. Solutions exist which are satisfactory for the most situations. However, rational solutions still have to be found for a few specific situations. (author)

    Full text: Individual Monitoring Service (IMS) is a dosimetry service provided by Radiation Protection Department (RPD) of Sudan Atomic Energy Commission (SAEC) to monitor about 400 occupational exposed workers all over the country. Measurements were done using thermoluminescence dosimeters (TLD). The calibration of the TLD system was performed on a phantom with application of suitable correction factors in the SSDL using Cs-137 and different qualities of x-ray energies. Personal dose equivalents Hp(10) and Hp(0.07) were evaluated by employing one individual dosimeter to be carried continuously by the occupational exposed person while at work. In this work the dose received by workers in x-ray diagnostic radiology, radiotherapy, nuclear medicine, research and industrial radiography were evaluated. Radiation doses for the years 1999, 2000, 2001, 2002 and 2003 were compared. From the results obtained, it was noticed that individual monitoring service had expanded over the last years. The average individual annual dose in different applications is less than 1 mSv/y except for the workers in industrial radiography, only 12 radiation workers (3.64 %) received doses exceeding 1 mSv and no individual approached the dose limit of 20 mSv recommended by the ICRP and set by Sudan's regulations.

    The EURADOS Working Group II on 'Harmonisation of individual monitoring' consists of experts from almost all EU Member States and Newly Associated States (NAS), involved in tasks related to the assessment of doses for internal and external radiation. The final objective is to achieve harmonisation in individual monitoring for occupational exposures. Sub-group 2 activities are focused on investigating how the results from personal dosemeters for external radiation and workplace monitoring and from monitoring for internal exposure can be combined into a complete and consistent system of individual monitoring. Three questionnaires were prepared, covering Individual monitoring of external radiation (Questionnaire 1), 'Internal exposure' (Questionnaire 2) and 'Natural sources of radiation at workplace' (Questionnaire 3). With the agreement of a 'contact-person' selected in each country, the distribution of the three EURADOS 2002 questionnaires was carried out by e-mail among the dosimetry facilities of 28 European countries. The preliminary results of these actions are presented here. (author)

  17. Assessment of occupational exposure due to external sources of radiation. Safety guide

    International Nuclear Information System (INIS)

    2000-01-01

    Occupational exposure to ionizing radiation can occur in a range of industries, medical institutions, educational and research establishments and nuclear fuel cycle facilities. Adequate radiation protection of workers is essential for the safe and acceptable use of radiation, radioactive materials and nuclear energy. The three Safety Guides on occupational radiation protection are jointly sponsored by the IAEA and the International Labour Office. The Agency gratefully acknowledges the contribution of the European Commission to the development of the present Safety Guide. The present Safety Guide addresses the assessment of exposure due to external sources of radiation in the workplace. Such exposure can result from a number of sources within a workplace, and the monitoring of workers and the workplace in such situations is an integral part of any occupational radiation protection programme. The assessment of exposure due to external radiation sources depends critically upon knowledge of the radiation type and energy and the conditions of exposure. The present Safety Guide reflects the major changes over the past decade in international practice in external dose assessment

    Currently in Brazil (2016), there are 421 Nuclear Medicine Services (NMS). In nuclear medicine, the possibility of occupational internal contamination and external exposure is unavoidable. The chest individual monitoring, to estimate the effective dose, is mandatory, but the extremity monitoring is not always made. The aim of this study was to conduct a survey of data for external exposure of NMS professionals in Brazil from 1987 to 2010, analysing them in terms of trends and comparing them with measurements carried out in this work and in other countries. Although most of the NMS is still located in large urban centres (54% in the Southeast region), there is no state without any NMS. The increasing number of NMS has generated the need for more professionals. In the year 1987, they were 755 workers and, in 2010, 4134, with the following distribution of specialties: 29% of Nuclear Medicine Technicians (NMT), 23% of Nursing professionals, 29% of Physicians and 3% of Physicists. The average annual effective dose reached more than 3.0 mSv in some regions of the country, from 1987 to 2010, but tends to 1.0 mSv in 2010. The highest doses, as expected, are received by NMT and Nursing. The professionals who handle radiopharmaceuticals have their hands much more exposed than the chest. During 2010, only 31% of NMT and 16% of Nursing used extremity dosimeters as compared to chest dosimeters. The data from the measurements indicate that not all individual dosimeters are used properly. Generally, both in the measurements as in national registries, the hand doses were higher for professionals who prepared the radiopharmaceutical (NMT) than those who injected (Nursing). The value measured by chest dosimeters can be used to estimate the equivalent dose to the eye lenses, except for NMT at preparation practices at conventional NMS, where the equivalent dose of the lens is about 2 times higher than the dose at the chest. The most exposed areas of the hands are the tips of the index

    Brazilian Nuclear Energy Commission (CNEN) has been carrying out an accreditation program for the External Individual Monitoring Services (named SMIE) for about 45.000 workers involved with ionizing radiation. One of this steps of this accreditation program is the audit to each SMIE. The main audit objective is to verify and to check organizational documentation, system performance test, technical personnel ability and training, quality assurance system procedures and records, essential equipment and facilities and reliability of dose reports. In order to avoid a different audit for each SMIE, effort were made to obtain a standard process. Two aspects were considered the most relevant ones: human resources training and audit procedures. To achieve the first one, a practical and theoretical course taking into account auditing needs was elaborated. As well as experience in one of the technical related areas, an important condition to be member of an audit team is to obtain satisfactory approval in one of the offered courses. In order to accomplish the second point, a set of documents was implemented such as an audit checklist, audit report models, and procedures and recommendations to audit. Up to February 1998, 12 accreditation audits were performed. The main points of this program as well as an assessment of its difficulties and success are reported in this work

    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.

    Full Text Available Introduction: Scientific studies show that occupational therapy interventions with patients after cerebral vascular accident (CVA - post-stroke patients, help them resume the performance of important meaningful tasks. Objective: To measure changes in the perception of post-stroke patients on their occupational performance and satisfaction after the intervention of occupational therapy. Methodology: An observational, longitudinal, prospective study with CVA patients treated at occupational therapy service at the ‘Unidade Mista de Taguatinga’, Federal District, Brazil. The Canadian Occupational Performance Measure (COPM was applied in three distinct times: during the initial assessment (time 1, after 3 months (time 2, and after 6 months (time 3 of occupational therapy intervention. Results: The analysis after 3 months of intervention was performed with 17 patients; all showed increased performance scores (p = 0.000, and only one patient presented decrease in satisfaction scores. The analysis after 6 months was conducted with 13 patients; all showed significant improvement (p = 0.000 in scores for performance and satisfaction. Conclusions: The study shows the improvement in satisfaction and occupational performance of CVA patients after occupational therapy intervention. The study suggests that occupational therapy intervention helps the rehabilitation process of post-stroke patients, enabling them to improve their occupational performance and satisfaction and, consequently, their independence.

    In this work, we have evaluated the possibility of applying the Monte Carlo simulation technique in photon dosimetry of external individual monitoring. The GEANT4 toolkit was employed to simulate experiments with radiation monitors containing TLD-100 and CaF 2 :NaCl thermoluminescent detectors. As a first step, X ray spectra were generated impinging electrons on a tungsten target. Then, the produced photon beam was filtered in a beryllium window and additional filters to obtain the radiation with desired qualities. This procedure, used to simulate radiation fields produced by a X ray tube, was validated by comparing characteristics such as half value layer, which was also experimentally measured, mean photon energy and the spectral resolution of simulated spectra with that of reference spectra established by international standards. In the construction of thermoluminescent dosimeter, two approaches for improvements have. been introduced. The first one was the inclusion of 6% of air in the composition of the CaF 2 :NaCl detector due to the difference between measured and calculated values of its density. Also, comparison between simulated and experimental results showed that the self-attenuation of emitted light in the readout process of the fluorite dosimeter must be taken into account. Then, in the second approach, the light attenuation coefficient of CaF 2 :NaCl compound estimated by simulation to be 2,20(25) mm -1 was introduced. Conversion coefficients C p from air kerma to personal dose equivalent were calculated using a slab water phantom with polymethyl-metacrilate (PMMA) walls, for reference narrow and wide X ray spectrum series [ISO 4037-1], and also for the wide spectra implanted and used in routine at Laboratorio de Dosimetria. Simulations of backscattered radiations by PMMA slab water phantom and slab phantom of ICRU tissue-equivalent material produced very similar results. Therefore, the PMMA slab water phantom that can be easily constructed with low

    Background Catastrophic thinking has been associated with occupational disability in individuals with debilitating pain conditions. The relation between catastrophic thinking and occupational disability has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between catastrophic thinking and occupational disability in individuals with major depression. Methods The study sample consisted of 80 work-disabled individuals with major depressive disorder (MDD) who were referred to an occupational rehabilitation service. Participants completed measures of depressive symptom severity, catastrophic thinking and occupational disability at admission and termination of a rehabilitation intervention. Return-to-work outcomes were assessed 1 month following the termination of the rehabilitation intervention. Results Cross-sectional analyses of admission data revealed that catastrophic thinking contributed significant variance to the prediction of self-reported occupational disability, beyond the variance accounted for by depressive symptom severity. Prospective analyses revealed that reductions in catastrophic thinking predicted successful return to work following the rehabilitation intervention, beyond the variance accounted for by reductions in depressive symptom severity. Conclusions The findings suggest that catastrophic thinking is a determinant of occupational disability in individuals with major depressive disorder. The findings further suggest that interventions designed to reduce catastrophic thinking might promote occupational re-integration in individuals with debilitating mental health conditions.

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

    Individuals living near the Nevada Test Site were exposed to both beta and gamma radiations from fission products and activation products resulting from the atmospheric testing of nuclear devices. These exposures were functions of the amount of material deposited, the time of arrival of the debris, and the amount of shielding afforded by structures. Results are presented for each of nine generic life styles. These are representative of the living patterns of the people residing in the area. For each event at each location for which data exist, a representative of each life style was closely followed for a period of thirty days. The results of these detailed calculations are then extrapolated to the present. 7 refs., 5 figs., 2 tabs

    Occupational exposure data of workers due to external sources of radiation in various medical practices such as nuclear medicine (NM), radiotherapy and diagnostic radiology (DR) in Pakistan were collected and analysed. Whole-body doses of workers were measured by film badge dosimetry technique during 2003-2007. Annual average effective dose in NM, radio-therapy and DR varied in the range of 1.39-1.80, 1.05-1.45 and 1.22-1.71 mSv, respectively, during 2003-2007. These values are quite low and well below the annual limit of 20 mSv averaged over a period of 5 consecutive years. Nobody received the radiation dose >50 mSv in any single year over a period of 5 consecutive years; therefore, no overexposure case has been detected. Decreasing trend of annual average dose values in aforementioned categories of work during 2003-2007 indicates the improvement of radiation protection status in medical field in Pakistan. (authors)

    As a part of the China-Japan cooperative research on the natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external to natural radiation in the high background radiation area (HBRA) of Yangjiang in Guangdong province and in the control area (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all inhabitants directly by the personal dosimeters, an indirect method was applied to estimate the exposed dose rates from the environmental radiation dose rates measured by survey meters and the occupancy factors of each hamlet. An individual radiation dose roughly correlates with the environmental radiation dose and the life style of the inhabitant. We have analyzed the environmental radiation doses in the hamlets and the variation of the occupancy factors to obtain the parameters of dose estimation on the inhabitants in selected hamlets; Madi and the several hamlets of the different level doses in HBRA and Hampizai hamlet in CA. With these parameters, we made estimations of individual dose rates and compared them with those obtained from the direct measurement using dosimeters carried by selected individuals. The results obtained are as follows: 1) The environmental radiation dose rates are influenced by the natural radioactive nuclide concentrations in building materials, the age of the building and the arrangement of the houses in a hamlet. There existed a fairly large and heterogeneous distribution of indoor and outdoor environmental radiation. The indoor radiation dose rates were due to the exposure from the natural radioactive nuclides in the building materials and they were about twice higher than the outdoor radiation dose rates. This difference was not observed in CA. 2) The occupancy factor was affected by the age of individuals and the seasons of a year. Indoor occupancy factors were higher for infants and aged individuals than for other age groups. This lead to higher

    2002-01-01

    The annual radiation dose to the group of external personnel working in nuclear facilities accounts for more than 39% of the total annual collective dose of all occupationally exposed persons in Germany. This is a fact causing problems for plant operators employing external personnel as well as the sending companies, with respect to compliance with the radiation protection regulations. The amended German Radiation Protection Ordinance does not really make things easier in this respect, but in fact is expected to aggravate the situation in the course of increasing globalisation in the industrial sector.

    2008-02-01

    Full Text Available Abstract Background Knee osteoarthritis (OA is one of the frequent and functionally impairing disorders of the musculoskeletal system. In the literature, a number of occupational risk factors are discussed as being related to the development and progress of knee joint diseases, e.g. working in kneeling or squatting posture, lifting and carrying of heavy weights. The importance of the single risk factors and the possibility of prevention are currently under discussion. Besides the occupational factors, a number of individual risk factors are important, too. The distinction between work-related factors and individual factors is crucial in assessing the risk and in deriving preventive measures in occupational health. In existing studies, the occupational stress is determined mainly by surveys in employees and/or by making assumptions about individual occupations. Direct evaluation of occupational exposure has been performed only exceptionally. The aim of the research project ArGon is the assessment of different occupational factors in relation to individual factors (e.g. constitutional factors, leisure time activities, sports, which might influence the development and/or progression of knee (OA. The project is designed as a case control study. Methods/Design To raise valid data about the physical stress associated with occupational and leisure time activities, patients with and without knee OA are questioned by means of a standardised questionnaire and an interview. The required sample size was estimated to 800 cases and an equal number of controls. The degree and localisation of the knee cartilage or joint damages in the cases are documented on the basis of radiological, arthroscopic and/or operative findings in a patient record. Furthermore, occupational exposure is analysed at selected workplaces. To evaluate the answers provided in the questionnaire, work analysis is performed. Discussion In this research project, specific information on the

    The good of individual monitoring for external radiation is the assessment of occupational exposure from X and γ radiations in order to assure that the radiological conditions of the workplace are acceptable, safe and satisfactory. The evaluation of radiations doses for workers must not exceed dose limits specified for workers, according to national regulatory agencies. Nowadays, there are two external monitoring systems in use, both based on ICRU definitions. In the conventional system, the workers doses are evaluated in terms of Hx. The personal dosimeter is worn over chest surface and it is calibrated in function of air kerma. In the new system, the workers doses are evaluated in terms of HP(d) and the personal dosimeter is calibrated in function of phantom doses. The aim of this paper is to adapt an external dosimetry laboratory (based on photographic dosimetry) to evaluate the personal dosimeters in terms of HP(d). In this way, a simple methodology, based on linear programming, was utilized. In this adaptation, calibration curves were obtained for radiation qualities (W and N series) described by International Organization for Standardization (ISO 4037-1, 1995). These calibration curves offer a better accuracy on dose determinations and energy below 140 keV, improving the quality of service rendered the society. (author)

    In recent decades several groups of researchers have been interested in describing and understanding vocal morbidity in teachers in order to explain the large number of teachers diagnosed with dysphonia and account for the absenteeism attributed to vocal disability. To determine the proportion of teachers who reported a diagnosis of dysphonia and measure associations between individual and contextual factors and the event of interest. Teachers were recruited from the city of Belo Horizonte and invited to complete a web-based institutional intranet questionnaire. In total, 649 teachers responded; 32% (CI 28.5-35.5) reported that they had received a physician diagnosis of dysphonia. This prevalence was significantly higher among female teachers (prevalence ratio (PR) 2.33; CI 1.41-3.85), and groups who reported limited technical resources and equipment (PR 1.56; CI 1.14-2.15), a diagnosis of gastritis (PR 1.59; CI 1.28-1.98), not being summoned for an annual physician examination (PR 0.47; CI 0.32-0.68), or absenteeism (PR 1.39; CI 1.06-1.81). The high prevalence of dysphonia in teachers was not associated with any individual variables, except for sex and comorbidity (diagnosis of gastritis). Limited technical resources and equipment were associated with dysphonia and suggests policy change is important in preventing dysphonia.

    Lead is a ubiquitous pollutant in the industrial environment, which poses serious threats to human health. In the past 20 years increasing attention has been paid to the effects of lead exposure on health. This toxic metal alters the immune response of animals as well as humans. To study the immunological effects of occupational exposure to lead, we examined lymphocyte proliferation, natural killer (NK) cell cytotoxicity and interferon-γ production with peripheral blood mononuclear cells (PBMCs) of individuals occupationally exposed to lead. We selected three different groups of individuals exposed to lead: three-wheeler drivers (30), battery workers (34) and silver jewelery makers (20); and unexposed healthy volunteers (30) as control for comparison. Our results indicate that though lymphocyte proliferation to phytohaemagglutinin (PHA) is inhibited in lead exposed individuals as compared with unexposed volunteers, there is no correlation between inhibition of lymphocyte proliferation and blood lead level. NK cell cytotoxicity remains unaffected in individuals exposed to lead as compared with controls. On the other hand, we observed that interferon-γ (IFN-γ) was significantly elevated in T cell mitogen, PHA, stimulated PBMCs culture supernatant of lead exposed individuals. We found significant positive correlation between blood lead levels and IFN-γ produced in culture supernatant on stimulation with PHA. In brief, this study demonstrates that lead can affect the immune response of the occupationally exposed individuals such as three-wheeler drivers, battery reconditioning workers and silver jewelery makers

    A large pool of evidence supports the beneficial effect of an external focus of attention on motor skill performance in adults. In children, this effect has been studied less and results are inconclusive. Importantly, individual differences are often not taken into account. We investigated the role of working memory, conscious motor control, and task-specific focus preferences on performance with an internal and external focus of attention in children. Twenty-five children practiced a golf putting task in both an internal focus condition and external focus condition. Performance was defined as the average distance toward the hole in 3 blocks of 10 trials. Task-specific focus preference was determined by asking how much effort it took to apply the instruction in each condition. In addition, working memory capacity and conscious motor control were assessed. Children improved performance in both the internal focus condition and external focus condition (ŋ p 2  = .47), with no difference between conditions (ŋ p 2  = .01). Task-specific focus preference was the only factor moderately related to the difference between performance with an internal focus and performance with an external focus (r = .56), indicating better performance for the preferred instruction in Block 3. Children can benefit from instruction with both an internal and external focus of attention to improve short-term motor performance. Individual, task-specific focus preference influenced the effect of the instructions, with children performing better with their preferred focus. The results highlight that individual differences are a key factor in the effectiveness in children's motor performance. The precise mechanisms underpinning this effect warrant further research.

    The dose load to subjects working with radiation sources in Bulgaria was analysed on the basis of data obtained from the Centralized System for Individual Dosimetric Control. Personnel film- and thermoluminenscent dosimetry had been used for monitoring of about 8000 persons including 66% medical personnel (54% of them practicians, 12% - researchers), 28% industrial personnel, 6% - working in the science/education sphere. The external irradiation is prevailing. The average annual equivalent doses (AAED) by branches were: medicine 0.6 - 0.9 mSv/a, industry 1.3 - 3.1 mSCv/a, science/education 1.0 - 1.2 mSv/a. The most badly loaded contingent (≤ 5 mSv/a) were the gamma-defectoscopists, which represent one third of the group of industrial workers. The irradiation levels in X-ray and radioisotope diagnosis are low. Similar are also the conclusions derived from the comparison of the weighted average annual equivalent doses (WAAED): medicine 0.85 mSv/a; industry 2.3 mSv/a; science/education 1.1 mSv/a. Higher than the average one for respective areas is the irradiation in gamma-defectoscopy, radiotherapy and services for electromedical equipment. The WAAED for the contingent in this study was 1.3 mSv/a, and 95% of AAED received were lower than 5 mSv/a. The low probability of irradiation with doses higher than 50 mSv/a in medicine and industry was established. 2 tabs., 2 figs., 6 refs

    The study objective was to elucidate coping strategies utilized by individuals recovered from schizophrenia. This qualitative study enrolled individuals with schizophrenia who had reached a level of recovery defined by their occupational status. Diagnosis of schizophrenia was confirmed with the Structured Clinical Interview for DSM-IV. Current symptoms were objectively rated by a clinician. Surveys gathered information on demographic characteristics, occupation, salary, psychiatric history, treatment, and functioning. Audio-recorded person-centered qualitative interviews gathered accounts of coping strategies. Transcripts were summarized and coded with a hybrid deductive-inductive approach. Twenty individuals were interviewed, including ten men. The average age was 40 years. Sixty percent of participants were either currently in a master's-level program or had completed a master's or doctoral degree. Eight categories of coping strategies were identified: avoidance behavior, utilizing supportive others, taking medications, enacting cognitive strategies, controlling the environment, engaging spirituality, focus on well-being, and being employed or continuing their education. Some strategies were used preventively to keep symptoms from occurring; others were used to lessen the impact of symptoms. Strategies were flexibly utilized and combined depending on the context. Use of strategies in a preventive fashion, the effectiveness of the identified strategies, and the comfort individuals expressed with using several different strategies supported these individuals in achieving their occupational goals. The findings contribute to an overall shift in attitudes about recovery from schizophrenia and highlight the importance of learning from people with lived experience about how to support recovery.

    This article develops and tests a structurally based, integrated theory of person-team fit. The theory developed is an extension of structural contingency theory and considers issues of external fit simultaneously with its examination of internal fit at the team level. Results from 80 teams working on an interdependent team task indicate that divisional structures demand high levels of cognitive ability on the part of teammembers. However, the advantages of high cognitive ability in divisional structures are neutralized when there is poor external fit between the structure and the environment. Instead, emotional stability becomes a critical factor among teammembers when a divisional structure is out of alignment with its environment. Individual differences seem to play little or no role in functional structures, regardless of the degree of external fit.

    International Nuclear Information System (INIS)

    1999-12-01

    This TECDOC presents the results of a Co-ordinated Research Project on Intercomparison for Individual Monitoring of External Exposure from photon radiation. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS) have endorsed the use of the operational quantities for monitoring purposes. Specifically, personal dose equivalent, H p (d), is to be used for individual dosimetry to demonstrate compliance with the exposure limit recommendations, while for workplace area monitoring the ambient dose equivalent and the directional dose equivalent are recommended. In view of the technical difficulties associated with the introduction of these operational quantities the IAEA decided to assist Member States in their provision of appropriate dosimetry for occupational protection. In this respect, intercomparisons have proven to be a cost effective method of providing such support. A Co-ordinated Research Project (CRP) was started in 1997 on Intercomparison for Individual Monitoring of External Exposure from photon radiation, involving more than twenty laboratories from eastern Europe and the countries of the former Soviet Union, and focusing on personnel dosimetry services for nuclear power plants. This CRP was part of the activities of the IAEA Occupational Protection Programme, the objective4s of which are to promote and internationally harmonized approach for optimizing occupational radiation protection through: the development of guides, within the IAEA activities for establishing standards for radiation protection, for restricting radiation exposures in the workplace and for applying current occupational radiation protection techniques, and the promotion of the application of these guidelines. The preparatory phase included, in May 1997, a workshop aimed at familiarizing the participants with the new operational quantities

    The institute for Radiation Protection of ENEA - Bologna has organised a one day-workshop on the subject: Individual monitoring of external exposure in terms of personal dose equivalent, H p (d). The aim of the workshop was the discussion of the new implications and modifications to be expected in the routine individual monitoring of external radiation, due to the issue of the Decree 241/00 (G.U. 31/8/2000) in charge since 01/01/2001. The decree set up in Italian law the standards contained in the European Directive EURATOM 96/29-Basic Standards for the Protection of Health of Workers and the General Public against Dangers arising from Ionizing Radiation. Among others, the definition of the operational quantities for external radiation for personal and environmental monitoring, H p (d) e H * (d) respectively as defined by ICRU (International Commission for Radiation Units and Measurements), requires to update the methods of measurements and calibration of the personal dosemeters and environmental monitors. This report collects the papers presented at the workshop dealing with the Personal Dose Equivalent, H p (d), the conversion coefficients, H p (d)/K a e H p (d)/ , obtained through Monte Carlo calculations published by ICRU and ICRP (International Commission for Radiation Protection), the new calibration procedures and the practical implication in the routine of individual monitoring in terms of H p (d). Eventually, in the last chapter, the answers to Frequently Asked Questions (FAQ) are briefly reported [it

    By legal determination, workers exposed to ionizing radiation should use individual dosimeters in the most exposed region of the body, designed to estimate the effective dose, as well as radiation protective clothing to minimize occupational exposures. Regarding dosimetry, in most cases it is perceived that the monthly values of exposure are within the limits of normality, however, even being below the limit can not rule out the possibility of damage that the low dose of ionizing radiation can cause. The objective of this article is to highlight the main chemical effects caused by exposure to ionizing radiation, especially biochemical damage in DNA, chromosomal aberrations and the correlation with the exposure of occupationally exposed individuals, as well as individuals from the public. A bibliographic search was carried out in indexed databases from February to April 2017 with the following descriptors: Radiation Ionizing, DNA Damage and Occupational Exposure. In the 'Science Direct' database were found 1205 articles, in the 'Scopus' 19 articles, in the 'Web of Science' 83 articles, in the 'PubMed' 22 articles and in the 'VHL' 60 articles related to the theme. It was concluded that exposure to ionizing radiation can affect the DNA molecule despite its repair mechanisms, which may result in genotoxicity. It has been reported a correlation between occupationally exposed individuals and chromosomal aberrations, demonstrating that even low doses of ionizing radiation can compromise the genetic material integrity of exposed workers, leading to the need for a periodic cytogenetic study for this group of workers

    Japanese teachers are mentally and physically burdened with various work stressors. This cross-sectional study examined the relationship between depressive symptoms and perceived individual level occupational stress including role problems among Japanese schoolteachers. This study included 1,006 teachers working in public schools in a Japanese city. The Japanese version of Zung's Self-Rating Depression Scale (SDS) was used to evaluate depressive symptoms, and the Generic Job Stress Questionnaire was used to evaluate occupational stress and three measures of social support. Subjects with SDS scores of more than 50 were categorized into the "depressive group." We examined the relationship between depressive symptoms and perceived individual level occupational stress using multiple logistic regression analyses. A total of 202 (20.1%) teachers belonged to the depressive group. We found that high role ambiguity, high role conflict, high quantitative workload, and low social support from family or friends were significantly related to depressive symptoms. To moderate role ambiguity and role conflict experienced by teachers, it is necessary to clarify the priority order of teachers' work. Furthermore, it is necessary to reduce workload by focusing on the content of teachers' work and the setting of education itself. Focusing on these elements will reduce teachers' depressive symptoms.

    Simultaneous microscopic imaging and spectroscopy of individual aerosol particles were performed with an external microbeam. Visible luminescence induced by the external microbeam was successfully used as a probe to detect organic contaminants in the targets. Combined ion luminescence (IL)/particle-induced X-ray emission (PIXE) analysis of the aerosol targets revealed microscopic chemical and elemental composition distributions under ambient atmospheric conditions. The simple confocal micro-optics for the IL spectroscopy and microscopic imaging were sufficiently sensitive for detecting these molecules at sub-parts per million concentrations and at a wavelength resolution of less than 5 nm. The IL spectra were monitored to prevent severe damage to the samples. Furthermore, our IL system has the advantage that it is simple to add to a conventional micro-PIXE system.

It can protect from arbitrary managerial power and lead to employees’ personal development through sharing organizational resources, influencing leadership activities and joint decision making in companies. The study examines individually perceived autonomy as an antecedent and employees......’ occupational self-efficacy as an outcome of DLA over time. Furthermore, the study tests the mediating role of DLA on the autonomy – self-efficacy relationship. The two-wave study applied an online survey in a Danish municipality with a time lag of seven months. We used regression analyses for testing the cross......-sectional as well as cross-lagged relationships and an autoregressive model for analyzing the half-longitudinal mediation. The results revealed a significant positive effect of DLA on employees’ occupational self-efficacy cross-sectionally at Time 1 (n = 117) and Time 2 (n = 67), as well as cross-lagged (n = 67...

    Physical and psychomotor development of children whose grandparents were occupationally exposed to chronic external gamma-radiation at doses 0.1 to over 400 Gy was studied. Mean values of the major anthropometric parameters at first and over the first year of life, growth and mass increment rates were assessed, as well as body length growth per quarter, age of the doubling and tripling the body mass at birth, and age of the cross-over of the head and chest circumference values. Share of infants with the harmonic and dysharmonic development, of those small-for-date and large-for-date were estimated, and the psychomotor development and the rate of biologic maturation were assessed. No significant differences between studied parameters of the test group and the reference group were detected

    The Santa Quitéria Project (PSQ) is an enterprise that aims at the production of phosphate compounds as main products, and of uranium concentrates as by-products from minerals of the Itataia deposit. The intended area for implementation of the project is located in the municipality of Santa Quitéria, north central region of the State of Ceará. The U.S. Nuclear Regulatory Commission lists the basic design accidents for a Uranium Processing Plant, such as the PSQ. Among all these scenarios, fire in uranium extraction cells was the one with the highest doses released. For simulation of the fire event, the atmospheric dispersion model used was the standard Gaussian plume model. The doses were calculated for two sets of meteorological conditions: stability class F, with wind velocity of 1 m/s and class D stability with wind velocity of 4.5 m/s. For PSQ, it was considered that there will be no public individual until after 2000 meters from the release point. The doses corresponding to the occupationally exposed individuals are: 2.0E-3 mSv (class D) and 5 mSv (Class F), 300 meters away from the event. Analyzing the results, it can be concluded that there are no significant radiological consequences for the occupationally exposed individual, both in the stability class D and the F. The doses of the workers are well below the levels that could cause deterministic effects. Even if an occupationally exposed individual were exposed for 12 hours in the center of the plume, the dose received would not exceed the annual limit established by CNEN. (author)

    This is a report of the yearly changes of exposure received by workers in radiological occupations at Fukuoka University Hospital from August 1973 to December 1980. The total number of the workers during this period involving diagnostic radiology, radiotherapy and the other related fields included 153 physicians, 27 technicians, 29 nurses and 16 assistants. Out of 225 workers, only two angiographers and two involved in intracavitary radiation therapy received more than 500 mrem of the annual exposure dose. The highest dose was 610 mrem. The exposure doses have gradually decreased each year. The exposure of the workers has remarkably decreased to almost negligible since a remote afterloading system was installed for intracavitary radiation therapy. In no worker was any somatic effect of radiation detected in the periodical physical examinations, even in the number of lymphocytes in the peripheral blood. (author)

The current findings suggest that sRPE and HR-based internal TL measures provide a valid tool for quantifying volume of external TL during WR training but may underestimate HIA. It is recommended that both internal and external TL measures are employed for the monitoring of overall TL during court-based training in elite WR athletes.

    Workplace stress and its impact upon retention levels are becoming an increasing concern within the teaching profession (Brown, Davis, & Johnson, 2002; Jarvis, 2002). Research has largely focused upon the effects of environmental factors, whilst noting that it is the interplay between the individual and the environment which may hold the key to understanding this problem (Cox, 1978; Parkes, 1994). Identifying individual contributory factors is essential in understanding why, under the same environmental conditions, some people suffer much greater levels of stress than others. This study examined the influence of Type A behaviour, personal achievement strivings, occupational commitment, gender and nature/experience of teaching on perceived workplace stress within the teaching profession (N = 95). It was predicted that perceived stress would be strongest amongst those reporting higher levels of these factors. A multiple regression analysis indicated that there was a positive relationship between Type A behaviour, personal achievement strivings, and perceived stress. The relationship between perceived stress and occupational commitment, however, was found to be negative. The possible explanations for these findings, and potential implications, are discussed. Future research plans are outlined for exploring the relationships between these individual contributory factors and environmental stressors.

    Workers who are not routinely monitored for occupational radiation exposure at LANL may be issued temporary dosimeters in the field. Per 10CFR835 and DOE O 231.1A, the Laboratory's radiation protection program is responsible for reporting these results to the worker at the end of the year. To do so, the identity of the worker and their mailing address must be recorded by the delegated person at the time the dosimeter is issued. Historically, this data has not been consistently captured. A new online application was developed to record the issue of temporary dosimeters. The process flow of the application was structured such that: 1) the worker must be uniquely identified in the Lab's HR database, and 2) the mailing address of record is verified live time via a commercial web service, for the transaction to be completed. A COPQ savings (Type B1) of $96K/year is demonstrated for the new application.

    This study identified relationships between occupational factors and health and well-being among individuals with persistent mental illness. There were 103 subjects assessed in regards to time spent in different occupations, activity level, satisfaction with daily occupations, and experienced occupational value. The health-related variables were self-rated health, quality of life, self-esteem, sense of coherence, self-mastery, psychosocial functioning, and psychiatric symptoms. Subjective perceptions of occupational performance were consistently related to both self-rated and interviewer-rated aspects of health and functioning. While variables pertaining to actual doing showed weak or no associations with self-rated health-related variables, they exhibited moderate relationships to interviewer-rated health and functioning. The health-promoting ingredients in occupations were determined by the way occupations were perceived, rather than the doing per se. The findings indicate that perceived meaning and satisfaction ought to be prioritized when setting goals in occupational therapy practice, and, besides, that existing occupational therapy theory needs to be updated.

    To examine the effect of mindfulness meditation on occupational functioning in individuals with Generalized anxiety disorder (GAD). Fifty-seven individuals with GAD (mean (SD) age=39 (13); 56% women) participated in an 8-week clinical trial in which they were randomized to mindfulness-based stress reduction (MBSR) or an attention control class. In this secondary analysis, absenteeism, entire workdays missed, partial workdays missed, and healthcare utilization patterns were assessed before and after treatment. Compared to the attention control class, participation in MBSR was associated with a significantly greater decrease in partial work days missed for adults with GAD (t=2.734, df=51, p=0.009). Interestingly, a dose effect was observed during the 24-week post-treatment follow-up period: among MBSR participants, greater home mindfulness meditation practice was associated with less work loss and with fewer mental health professional visits. Mindfulness meditation training may improve occupational functioning and decrease healthcare utilization in adults with GAD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available This study was conducted to compare the pattern of age-related hearing decline in individuals with and without self-reported previous occupational noise exposure. This was a prospective, population-based, longitudinal study of individuals aged 70-75 years, from an epidemiological investigation, comprising three age cohorts. In total there were 1013 subjects (432 men and 581 women. Participants were tested with pure tone audiometry, and they answered a questionnaire to provide information regarding number of years of occupational noise exposure. There were no significant differences in hearing decline, at any frequency, for those aged 70-75 years between the noise-exposed (N= 62 men, 22 women and the nonexposed groups (N = 96 men, 158 women. This study supports the additive model of noise-induced hearing loss (NIHL and age-related hearing loss (ARHL. The concept of different patterns of hearing decline between persons exposed and not exposed to noise could not be verified.

    Full Text Available The authors investigated the levels of anti-glycoprotein antibodies against rabies virus in the sera of occupationally exposed humans at the University of Ibadan, Nigeria. A quantitative indirect enzyme-linked immunosorbent assay (ELISA was used to detect rabies virus anti-glycoprotein antibodies in sera from 20 zoological garden workers, 20 veterinarians and 30 clinical veterinary students at the University of Ibadan. The sera were obtained between September 2008 and February 2009. Of these 70 healthy individuals, 29 (41.4% consisting of 15 zoological garden workers (75.0%, 13 veterinarians (65.0% and 1 veterinary student (3.3% were immune to rabies virus (antibody titre >0.5 equivalent units per ml, while 41 (58.6% were not immune. The prevalence of rabies anti-glycoprotein antibody was higher within the older segment of the study population than among the younger veterinary students. Almost all those who had spent at least 10 years on the job had higher levels of rabies vaccination compliance and were immune. Our results indicated that there is low anti-rabies immunity among occupationally exposed individuals at the University of Ibadan. There is a need for a complete course of primary and booster vaccinations of professionals exposed to the rabies virus. The impact of these results on rabies control in Nigeria is discussed.

  7. Does feather corticosterone reflect individual quality or external stress in arctic-nesting migratory birds?

    Directory of Open Access Journals (Sweden)

    Pierre Legagneux

    Full Text Available The effects of environmental perturbations or stressors on individual states can be carried over to subsequent life stages and ultimately affect survival and reproduction. The concentration of corticosterone (CORT in feathers is an integrated measure of hypothalamic-pituitary-adrenal activity during the molting period, providing information on the total baseline and stress-induced CORT secreted during the period of feather growth. Common eiders and greater snow geese replace all flight feathers once a year during the pre-basic molt, which occurs following breeding. Thus, CORT contained in feathers of pre-breeding individuals sampled in spring reflects the total CORT secreted during the previous molting event, which may provide insight into the magnitude or extent of stress experienced during this time period. We used data from multiple recaptures to disentangle the contribution of individual quality vs. external factors (i.e., breeding investment or environmental conditions on feather CORT in arctic-nesting waterfowl. Our results revealed no repeatability of feather CORT within individuals of either species. In common eiders, feather CORT was not affected by prior reproductive investment, nor by pre-breeding (spring body condition prior to the molting period. Individual feather CORT greatly varied according to the year, and August-September temperatures explained most of the annual variation in feather CORT. Understanding mechanisms that affect energetic costs and stress responses during molting will require further studies either using long-term data or experiments. Although our study period encompassed only five years, it nonetheless provides evidence that CORT measured in feathers likely reflects responses to environmental conditions experienced by birds during molt, and could be used as a metric to study carry-over effects.

    Full Text Available Prolonged exposure to high levels of occupational noise can cause damage to hair cells in the cochlea and result in permanent noise-induced cochlear hearing loss. Consequences of cochlear hearing loss on speech perception and psychophysical abilities have been well documented. Primary goal of this research was to explore temporal processing and speech perception Skills in individuals who are exposed to occupational noise of more than 80 dBA and not yet incurred clinically significant threshold shifts. Contribution of temporal processing skills to speech perception in adverse listening situation was also evaluated. A total of 118 participants took part in this research. Participants comprised three groups of train drivers in the age range of 30-40 (n= 13, 41 50 ( = 13, 41-50 (n = 9, and 51-60 (n = 6 years and their non-noise-exposed counterparts (n = 30 in each age group. Participants of all the groups including the train drivers had hearing sensitivity within 25 dB HL in the octave frequencies between 250 and 8 kHz. Temporal processing was evaluated using gap detection, modulation detection, and duration pattern tests. Speech recognition was tested in presence multi-talker babble at -5dB SNR. Differences between experimental and control groups were analyzed using ANOVA and independent sample t-tests. Results showed a trend of reduced temporal processing skills in individuals with noise exposure. These deficits were observed despite normal peripheral hearing sensitivity. Speech recognition scores in the presence of noise were also significantly poor in noise-exposed group. Furthermore, poor temporal processing skills partially accounted for the speech recognition difficulties exhibited by the noise-exposed individuals. These results suggest that noise can cause significant distortions in the processing of suprathreshold temporal cues which may add to difficulties in hearing in adverse listening conditions.

    The use of unsealed radiation sources in nuclear medicine can lead to important incorporation of radionuclides, especially for occupationally exposed individuals (OEIs) during production and handling of radiopharmaceuticals. In this study, computer simulation was proposed as an alternative methodology for evaluation of the absorbed dose distribution and for the effective dose value in OEIs. For this purpose, the Exposure Computational Model (ECM) which is named as FSUP (Female Adult Mesh - supine) were used. This ECM is composed of: voxel phantom FASH (Female Adult MeSH) in the supine position, the MC code EGSnrc and an algorithm simulator of general internal source. This algorithm was modified to adapt to specific needs of the positron emission from FDG-{sup 18}F. The obtained results are presented as absorbed dose/accumulated activity. To obtain the absorbed dose distribution it was necessary to use accumulative activity data from the in vivo bioassay. The absorbed dose distribution and the value of estimated effective dose in this study did not exceed the limits for occupational exposure. Therefore, the creation of a database with the distribution of accumulated activity is suggested in order to estimate the absorbed dose in radiosensitive organs and the effective dose for OEI in similar environment.

    External gamma-ray exposures from fallout originating at the Nevada Test Site (NTS) have been assigned to 6,507 individual subjects (1,177 leukemia cases and 5,330 control subjects) who died as Utah residents between 1952 and 1981. Leukemia cases were identified, confirmed, and classified by cell type from the Utah Cancer Registry, Utah State vital records, and medical records. Residential histories were obtained from the Deceased Membership File (DMF) of the Church of Jesus Christ of Latter-day Saints (LDS), supplemented by information from the LDS Church Census Records that were taken in 1950, 1955, and 1960-62. Control subjects were selected randomly within age strata from the DMF and were frequency-matched to the cases by age at death and for sex. Individual radiation exposures were assigned as a function of residence location and time interval for each residence during the fallout period (1951-1958) using geographic exposure data taken from the literature. Temporal distribution of exposure for subjects who resided in more than one locality or who were born or died during the fallout period was determined from data of other investigators. Calculated gamma-ray exposures for each place of residence were summed for each subject to yield the exposure to fallout from the NTS

    The accident at Fukushima Daiichi Nuclear Power Plant on March 11, 2011, released radioactive material into the atmosphere and contaminated the land in Fukushima and several neighboring prefectures. Five years after the nuclear disaster, the radiation levels have greatly decreased due to physical decay, weathering, and decontamination operations in Fukushima. The populations of 12 communities were forced to evacuate after the accident; as of March 2016, the evacuation order has been lifted in only a limited area, and permanent habitation is still prohibited in most of the areas. In order for the government to lift the evacuation order and for individuals to return to their original residential areas, it is important to assess current and future realistic individual external doses. Here, we used personal dosimeters along with the Global Positioning System and Geographic Information System to understand realistic individual external doses and to relate individual external doses, ambient doses, and activity-patterns of individuals in the affected areas in Fukushima. The results showed that the additional individual external doses were well correlated to the additional ambient doses based on the airborne monitoring survey. The results of linear regression analysis suggested that the additional individual external doses were on average about one-fifth that of the additional ambient doses. The reduction factors, which are defined as the ratios of the additional individual external doses to the additional ambient doses, were calculated to be on average 0.14 and 0.32 for time spent at home and outdoors, respectively. Analysis of the contribution of various activity patterns to the total individual external dose demonstrated good agreement with the average fraction of time spent daily in each activity, but the contribution due to being outdoors varied widely. These results are a valuable contribution to understanding realistic individual external doses and the corresponding

    In this study, we modelled population responses to chronic external gamma radiation in 12 laboratory species (including aquatic and soil invertebrates, fish and terrestrial mammals). Our aim was to compare radiosensitivity between individual and population endpoints and to examine how internationally proposed benchmarks for environmental radioprotection protected species against various risks at the population level. To do so, we used population matrix models, combining life history and chronic radiotoxicity data (derived from laboratory experiments and described in the literature and the FREDERICA database) to simulate changes in population endpoints (net reproductive rate R 0 , asymptotic population growth rate λ, equilibrium population size N eq ) for a range of dose rates. Elasticity analyses of models showed that population responses differed depending on the affected individual endpoint (juvenile or adult survival, delay in maturity or reduction in fecundity), the considered population endpoint (R 0 , λ or N eq ) and the life history of the studied species. Among population endpoints, net reproductive rate R 0 showed the lowest EDR 10 (effective dose rate inducing 10% effect) in all species, with values ranging from 26 μGy h −1 in the mouse Mus musculus to 38,000 μGy h −1 in the fish Oryzias latipes. For several species, EDR 10 for population endpoints were lower than the lowest EDR 10 for individual endpoints. Various population level risks, differing in severity for the population, were investigated. Population extinction (predicted when radiation effects caused population growth rate λ to decrease below 1, indicating that no population growth in the long term) was predicted for dose rates ranging from 2700 μGy h −1 in fish to 12,000 μGy h −1 in soil invertebrates. A milder risk, that population growth rate λ will be reduced by 10% of the reduction causing extinction, was predicted for dose rates ranging from 24 μGy h −1 in

    This paper reports the results of monitoring of medical workers occupationally exposed to ionizing radiation as a consequence of exposure to X-rays, from 2007 to 2010, in Burkina Faso. The radiation exposure monitoring was made with thermoluminescent dosimeters (TLD-100) type 0110 and the reader used was Harshaw 4500. The medical establishments. subscribers were provided with personal dosimeters (measuring Hp (10) and Hp (0.07)) and dosimeters for background and workplace exposure (H*10) measurement. The dosimeters have been worn for periods of 2 months each. The number of establishments subscribed and workers monitored has gradually increased from 4 radiology establishments with 13 workers monitored at September 2007 to 23 subscribers with 121 workers monitored at the end of April 2010. 13 establishments were still working without monitoring. From September 2007 to April 2010, no individual annual dose limit has really been reached. 88.16% of the 2 months dose values of personal dosimeters were below 0.1mSv, the detection limit and 96.61% of Hp (10) bimonthly values were below 3.33mSv. The workplace exposure monitoring values were often low (varying from 0.00mSv to 40.45mSv). 87.08% of the values of H*(10) were below 3.33mSv, the upper limit of Hp (10) for a period of 2 months. Low values of individual dose have also been recorded despite of high values of workplace monitoring. This allowed to state that the workers monitored were not exposed to a major risk. Nevertheless, 13 TLD have been lost and 3 damaged by subscribers (out of 1504 TLD provided). 26 times (out of 240), background measurement and workplace exposure monitoring dosimeters have been placed at the improper location. Therefore, sensitization of the establishments using ionizing radiation should be reinforced and the national regulations should impose radiation monitoring (author)

    Currently in Brazil (2016), there are 421 Nuclear Medicine Services (NMS). In nuclear medicine, the possibility of occupational internal contamination and external exposure is unavoidable. The chest individual monitoring, to estimate the effective dose, is mandatory, but the extremity monitoring is not always made. The aim of this study was to conduct a survey of data for external exposure of NMS professionals in Brazil from 1987 to 2010, analysing them in terms of trends and comparing them with measurements carried out in this work and in other countries. Although most of the NMS is still located in large urban centres (54% in the Southeast region), there is no state without any NMS. The increasing number of NMS has generated the need for more professionals. In the year 1987, they were 755 workers and, in 2010, 4134, with the following distribution of specialties: 29% of Nuclear Medicine Technicians (NMT), 23% of Nursing professionals, 29% of Physicians and 3% of Physicists. The average annual effective dose reached more than 3.0 mSv in some regions of the country, from 1987 to 2010, but tends to 1.0 mSv in 2010. The highest doses, as expected, are received by NMT and Nursing. The professionals who handle radiopharmaceuticals have their hands much more exposed than the chest. During 2010, only 31% of NMT and 16% of Nursing used extremity dosimeters as compared to chest dosimeters. The data from the measurements indicate that not all individual dosimeters are used properly. Generally, both in the measurements as in national registries, the hand doses were higher for professionals who prepared the radiopharmaceutical (NMT) than those who injected (Nursing). The value measured by chest dosimeters can be used to estimate the equivalent dose to the eye lenses, except for NMT at preparation practices at conventional NMS, where the equivalent dose of the lens is about 2 times higher than the dose at the chest. The most exposed areas of the hands are the tips of the index

    In spite of significant safety measures, allergy to industrial enzymes remains a major concern. The increasing prevalence of occupational allergy emphasizes the need to investigate the functional properties of enzyme-exposed dendritic cells (DCs), as DCs possess a potent ability to activate allergen-specific T cells. This study aims at elucidating the molecular mechanisms underlying allergic immune responses to lipase, an industrial enzyme. For this purpose, we studied the effect of both hypoallergenic and wild-type lipase on the transcriptional regulation in DCs and their stimulatory effect on memory CD4+ T cells. Five individuals with documented lipase allergy were tested for specific serum IgE. DCs from these individuals, stimulated with lipases, were assayed for their ability to affect proliferation and polarization of memory T cells. The effect of lipases on transcriptional activity in DCs was evaluated using global expression analysis. Lipase-specific IgE levels varied considerably between donors, with donor 4 exhibiting highest levels, and a potent specific CD4+ T cell recall response was demonstrated only for donor 4. No difference was detected in cytokine profile when T cells from donor 4 were co-cultured with DCs pulsed with either hypoallergenic or wild-type lipase, as demonstrated by high IL-4 and IL-13, and low IFN-gamma production. However, the lipases induced different genetic signatures in DCs from donor 4, as compared with the non-responders. DCs from individuals with clinically diagnosed allergy to lipase displayed a differential response to stimulation with hypoallergenic and wild-type lipase in vitro. Only allergen-pulsed DCs from donor 4 were able to induce CD4+ T cell proliferation. The lipase-specific T cells displayed a T-helper type 2 phenotype, which was not altered by hypoallergenic lipase-pulsed DCs. Furthermore, DCs derived from donor 4 and stimulated with either of the lipases displayed different transcriptional profiles, as compared

    The paper presents the Nofer Institutes of Occupational Medicine in Łódź's results of the assessment of individual dose equivalents Hp(0.07) of medical staff exposed to X-rays in Poland in 2012. In addition, the collected data was analysed in terms of types of medical units performing medical procedures and the categorization of personnel. Dosimetric service was provided for medical staff of interventional radiology departments occupationally exposed to ionizing radiation in terms of individual dose equivalents Hp(0.07). In 2012, personal dosimetry Hp(0.07) determinations were performed by the Nofer Institute of Occupational Medicine in Łódź and covered 2044 employees from 174 health facilities. The determinations were performed using thermoluminescence dosimetry according to the procedure accredited by the Polish Centre for Accreditation (document number AB 327). The measurements were performed using ring-dosimeters in the periods of 1 or 2 months. Mean annual individual dose equivalent Hp(0.07) in 2012 was equal to 3.3 mSv (annual limit for Hp(0.07) is 500 mSv). The average value of annual individual dose equivalent Hp(0.07) decreased comparing to the previous year. In 2012, no single case of exceeding the annual limit for Hp(0.07) was reported. Data stored in the file indicates that more than 96% of all of the annual doses did not exceed the level of 10 mSv. The analysis of data on occupational exposure to ionizing radiation confirms a stable level of exposure and satisfactory radiological protection in interventional radiology facilities monitored by the Nofer Institute of Occupational Medicine in Łódź in Poland in 2012.

    A dosimetric methodology was established for the determination of extremity doses of individuals occupationally exposed to beta radiation, using Al 2 O 3 :C detectors and the optically stimulated luminescence (OSL) reader system microStar, Landauer. The main parts of the work were: characterization of the dosimetric material Al 2 O 3 :C using the OSL technique; establishment of the dose evaluation methodology; dose rate determination of beta radiation sources; application of the established method in a practical test with individuals occupationally exposed to beta radiation during a calibration simulation of clinical applicators; validation of the methodology by the comparison between the dose results of the practical test using the OSL and the thermoluminescence (TL) techniques. The results show that both the OSL Al-2O 3 :C detectors and the technique may be utilized for individual monitoring of extremities and beta radiation. (author)

    The Pesticide Environmental Accounting (PEA) tool provides a monetary estimate of environmental and health impacts per hectare-application for any pesticide. The model combines the Environmental Impact Quotient method and a methodology for absolute estimates of external pesticide costs in UK, USA and Germany. For many countries resources are not available for intensive assessments of external pesticide costs. The model converts external costs of a pesticide in the UK, USA and Germany to Mediterranean countries. Economic and policy applications include estimating impacts of pesticide reduction policies or benefits from technologies replacing pesticides, such as sterile insect technique. The system integrates disparate data and approaches into a single logical method. The assumptions in the system provide transparency and consistency but at the cost of some specificity and precision, a reasonable trade-off for a method that provides both comparative estimates of pesticide impacts and area-based assessments of absolute impacts.

    A study of the impact of reducing the occupational radiation exposure limit from 5 rem/yr to 2.5, 1.0 and 0.5 rem/yr, respectively produced the following conclusions: reduction of the occupational exposure limit would result in significant increase in total accumulated exposure to the current radiation worker population and could require an increase in the work force; important programs would have to be abandoned at a planned exposure limit of 0.5 rem/yr; some engineering technology is not sufficiently developed to design or operate at the 0.5 rem/yr limit; even a factor of 2 reduction (2.5 rem/yr) would significantly increase costs and would result in an increase in total exposure to the work force; in addition to a significant one-time initial capital cost resulting from a 0.5 rem/yr limit, there would be a significant increase in annual costs; the major emphasis in controlling occupational exposure should be on further reduction of total man-rem; and current standards are used only as a limit. For example, 97% of the employees receive less than 0.5 rem/yr

    Full Text Available Introduction: Encoding of CE-chirp and click stimuli in auditory system was studied using auditory brainstem responses (ABRs among individuals with and without noise exposure. Materials and Methods: The study consisted of two groups. Group 1 (experimental group consisted of 20 (40 ears individuals exposed to occupational noise with hearing thresholds within 25 dB HL. They were further divided into three subgroups based on duration of noise exposure (0–5 years of exposure-T1, 5–10 years of exposure-T2, and >10 years of exposure-T3. Group 2 (control group consisted of 20 individuals (40 ears. Absolute latency and amplitude of waves I, III, and V were compared between the two groups for both click and CE-chirp stimuli. T1, T2, and T3 groups were compared for the same parameters to see the effect of noise exposure duration on CE-chirp and click ABR. Result: In Click ABR, while both the parameters for wave III were significantly poorer for the experimental group, wave V showed a significant decline in terms of amplitude only. There was no significant difference obtained for any of the parameters for wave I. In CE-Chirp ABR, the latencies for all three waves were significantly prolonged in the experimental group. However, there was a significant decrease in terms of amplitude in only wave V for the same group. Discussion: Compared to click evoked ABR, CE-Chirp ABR was found to be more sensitive in comparison of latency parameters in individuals with occupational noise exposure. Monitoring of early pathological changes at the brainstem level can be studied effectively by using CE-Chirp stimulus in comparison to click stimulus. Conclusion: This study indicates that ABR’s obtained with CE-chirp stimuli serves as an effective tool to identify the early pathological changes due to occupational noise exposure when compared to click evoked ABR.

    Internal radiation dose estimates for diagnostic nuclear medicine procedures are typically calculated for a reference individual. Resultantly, there is uncertainty when determining the organ doses to patients who are not at 50th percentile on either height or weight. This study aims to better personalize internal radiation dose estimates for individual patients by modifying the dose estimates calculated for reference individuals based on easily obtainable morphometric characteristics of the patient. Phantoms of different sitting heights and waist circumferences were constructed based on computational reference phantoms for the newborn, 10-year-old, and adult. Monoenergetic photons and electrons were then simulated separately at 15 energies. Photon and electron specific absorbed fractions (SAFs) were computed for the newly constructed non-reference phantoms and compared to SAFs previously generated for the age-matched reference phantoms. Differences in SAFs were correlated to changes in sitting height and waist circumference to develop scaling factors that could be applied to reference SAFs as morphometry corrections. A further set of arbitrary non-reference phantoms were then constructed and used in validation studies for the SAF scaling factors. Both photon and electron dose scaling methods were found to increase average accuracy when sitting height was used as the scaling parameter (~11%). Photon waist circumference-based scaling factors showed modest increases in average accuracy (~7%) for underweight individuals, but not for overweight individuals. Electron waist circumference-based scaling factors did not show increases in average accuracy. When sitting height and waist circumference scaling factors were combined, modest average gains in accuracy were observed for photons (~6%), but not for electrons. Both photon and electron absorbed doses are more reliably scaled using scaling factors computed in this study. They can be effectively scaled using sitting

    Objective: In order to estimate annual effective doses from external exposures in the high background radiation area (HBRA) and in the control area (CA) , the authors measured absorbed dose rates in air from terrestrial gamma radiation with different dosimeters. A dose group classification was an important step for analyzing the dose effects relationship among the cohort members in the investigated areas. The authors used the hamlet specific average annual effective doses of all the 526 hamlets in the investigated areas. A classification of four dose groups was made for the cohort members (high, moderate, low and control) . Methods: For the purpose of studying the dose effect relationships among the cohort members in HBRA and CA, it would be ideal that each subject has his own record of individual accumulated doses received before the evaluation. However, rt is difficult to realize it in practice (each of 106517 persons should wear TLD for a long time) . Thus the authors planned two sets of measurements. Firstly, to measure the environmental dose rates (outdoor, indoor, over the bed) in every hamlet of the investigated area (526 hamlets) , considering the occupancy factors for males and females of different age groups to convert to the annual effective dose from the data of dose rates. Secondly, to measure the individual cumulative dose with TLD for part of the subjects in the investigated areas. Results: Based on the two sets of measurements, the estimates of average annual effective doses in HBRA were 211.86 and 206.75 x 10 -5 Sv/a, respectively, 68.60 and 67.11 x 10 -5 Sv/a, respectively(gamma radiation only) . The intercomparison between these two sets of measurement showed that they were in good correlation. Thus the authors are able to yield the equations of linear regression: Y = 0.9937 + 6.0444, r = 0.9949. Conclusions: The authors took the value obtained from direct measurement as 'standard' , and 15 % for uncertainty of measurement. Since the estimates of

    The main source of radiation doses received by humans from man-made sources of ionizing radiation in medicine and industry comes from X-rays. The genetic risks of ionizing radiation effects on an individual who is occupationally exposed largely depend on the magnitude of the radiation dose received, period of practice, work load and radio logical procedures involved. In this work, using the linear non-thresh old model, we have attempted to assess the level of genetic risk of occupationally exposed individuals in two medical and industrial establishments in Nigeria by estimating their genetically significant dose values. The estimation was based on continuous personnel radiation dose monitoring data for the individuals in each of the establishments over a three year period (1998-2001). The estimated genetically significant dose values in the years considered were 12 mSv for the medical, and 29 mSv for the industrial personnel. Appropriate radiation protection precautions should be taken by the personnel to adhere to standard operational practices in order to minimize the genetically significant dose resulting from radio logical practices

    Many years of radiation exposure experience in all phases of nuclear energy applications were surveyed to evaluate the impact of reducing the present DOE limit of 5 rem/yr. Conclusions drawn are: (1) Reduction of the occupational exposure limit would result in significant increase in total accumulated exposure to the current radiation worker population and could require an increase in the work force with attending personnel and administrative problems. (2) Important programs/facilities would have to be abandoned. (3) Some engineering technology is not sufficiently developed to design or operate at the 0.5 rem/yr limit. (4) Exposure reduction to 2.5 rem/yr would significantly increase costs and would result in a small increase in total exposure to the work force. (5) Significant initial capital cost plus increased annual costs would result. (6) The major emphasis in controlling occupational exposure should be on continued work toward further reduction of total man-rem. This should involve continued development of ALAP programs along with improvements in dose measurement and recording methods, more sophisticated exposure records, and containment, handling and remote maintenance techniques. (7) Radiation protection practices at DOE facilities have maintained exposures of the bulk of the nuclear work force substantially below current limits for many years. (8) The current standards of 5 rem/yr is used only as a limit. For example, 97% of the employees receive less than 0.5 rem/yr

    Individual and organizational factors are the factors influencing traumatic occupational injuries. The aim of the present study was the short path analysis of the severity of occupational injuries based on individual and organizational factors. The present cross-sectional analytical study was implemented on traumatic occupational injuries within a ten-year timeframe in 13 large Iranian construction industries. Modeling and data analysis were done using the structural equation modeling (SEM) approach and the IBM SPSS AMOS statistical software version 22.0, respectively. The mean age and working experience of the injured workers were 28.03 ± 5.33 and 4.53 ± 3.82 years, respectively. The portions of construction and installation activities of traumatic occupational injuries were 64.4% and 18.1%, respectively. The SEM findings showed that the individual, organizational and accident type factors significantly were considered as effective factors on occupational injuries' severity (P factors and their indicator variables are very influential on the severity of traumatic occupational injuries. So, these should be considered to reduce occupational accidents' severity in large construction industries.

    The aim of this study was to analyse the perceived stress and individual resources of people involved in health and social welfare occupations, and evaluate whether belonging to different organisational structures leads to different reactions. To this end, we used the Maslach Burnout Inventory, the Coping Inventory for Stressful Situations, and the Team Climate Inventory. The sample consisted of 327 subjects (67% females) with a mean age of 35.9 +/- 8.8 years; most had a middle or high school diploma (63%), and they had been employed in the same place for about four years (47.5 +/- 7.3 months): 103 worked for health and social welfare cooperatives, and 224 for a local health authority. The results showed average burnout values and coping strategies prevalently aimed at directly solving the stressing situation in both working contexts. In comparison with the variables expressing the perceived organisational climate, sociodemographic characteristics did not seem to have a determining influence on the perception of individual stress. Comparison of the subjects employed in the two settings showed that organisational vision and a sense of belonging significantly determined subjective well-being, with the healthcare workers showed greater individual ill-being and a worse vision (i.e. an unclear perception of hospital choices and objectives). Our findings confirm that subjective well-being in high-touch occupations may be determined by the organisational culture: a mutual aid culture such as that of a cooperative has a protective effect despite the fact that the employment situation of the workers is more precarious and flexible than that of workers employed in highly structured environments such as that of a hospital.

    Full Text Available BACKGROUND: The aim of this study was to establish the sputum inflammatory profile and changes in levels of leukotriene B₄ (LTB₄ and a panel of Th1/Th2 cytokines in subjects with suspected occupational asthma (OA following specific inhalation challenge (SIC to high-molecular-weight (HMW and low-molecular-weight (LMW agents. MATERIAL AND METHODS: Fifty-one consecutive subjects undergoing SIC for suspected OA were enrolled. Sputum induction was performed the day before and 24 h after exposure to the offending agent. Total and differential cell counts were assessed. LTB₄ and a 10 Th1/Th2 cytokines were measured in sputum supernatant. RESULTS: Thirty-four patients tested positive to SIC and were diagnosed with OA (in 10 due to HMW agents and in 24 to LMW agents. SIC was negative in 17 subjects. As compared to baseline an increase was found in the percentage of sputum eosinophils and neutrophils, and in IL-10 concentration after SIC (p = 0.0078, p = 0.0195, and p = 0.046, respectively, and a decrease was seen in LTB₄ level (p = 0.0078 in patients with OA due to HMW agents. An increase in the percentage of sputum neutrophils after SIC (p = 0.0040 was observed in subjects without OA exposed to LMW agents. IL-8 levels after SIC were higher in patients without OA compared with patients with OA (p = 0.0146. CONCLUSION: When conducting airway inflammation studies in OA, patients should be divided according to the causal agent (HMW or LMW. In OA patients exposed to HMW agents, an increase in the number of neutrophils can be found in parallel to the increase of eosinophils, although this does not contradict an IgE-mediated mechanism. Exposure to LMW agents can result in increased neutrophilic inflammation in patients with airway diseases unrelated to OA. There is variability in the responses observed in patients with OA exposed to LMW agents.

    Monitoring and estimation of individual intakes of radionuclides can be complex. Doses of intakes cannot be measured directly, however must be assessed from the monitoring data of the individual. The individual monitoring data includes whole body counting, excretion analysis (urine or faecal). In the estimation of these data requires that the assessor makes assumptions about the exposure scenario, including the pattern and mode of radionuclide intake. Also physicochemical characteristics of the material involved and the period of time between exposure and measurement. This project report seeks to provide some underlying guidance on monitoring programmes and data interpretation using case study. In this present study the committed effective dose (CED) 1.20mSv exceeded the recording level (i.e. 1mSv) however it was below the investigation level (i.e. 2mSv). The present study recommends that as an essential part in internal dosimetry, specialists be capable of recognizing conditions warranting follow-up bioassay and dose evaluation. Personnel should be familiar with the relevant internal dosimetry literature and the recommendations of national and international scientific organizations with regard to internal dose. (au)

    After the Fukushima Daiichi nuclear power plant accident in 2011, Iitate village was placed under an evacuation order because the level of radioactive materials drifting from the nuclear plant to the village was above a government-set level for allowing residents to live in the area. The evacuation advisory for most of the village was lifted on 31 March 2017. For displaced residents deciding whether or not to return to their homes, it is important to correctly understand and estimate the realistic individual external doses they will receive after returning to the village. In this study, with the support of residents of the village, we used a personal dosimeter (D-Shuttle) coupled with a global positioning system device to measure and thus understand realistic individual external doses while the residents were in Iitate village and to project the individual external doses for different administrative districts as of 1 April 2017. The measured individual external doses measured by D-Shuttle for 38 study participants showed that the doses measured during time spent inside the village were higher and more widely distributed than the doses measured during time spent outside the village. The exposure ratio (ER) was defined as the ratio of additional individual external dose measured by D-Shuttle to the additional ambient dose based on an airborne monitoring survey. The medians of the average ERs were 0.13 (min-max 0.06-0.27) for time spent at home and 0.18 (min-max 0.08-0.36) for time spent outdoors. Projected additional annual individual external doses as of 1 April 2017 for different administrative districts in the village were calculated using ERs obtained in this study. Assuming that individuals spent 8 h per day on outdoor activities and 16 h on indoor activities, additional annual individual external doses were estimated to be below 3 mSv using the mean of the average ERs for most districts in the village, and these values were well below the individual external

    Full Text Available Background: Chronic exposure to noise is known to cause a wide range of health problems including extracellular matrix (ECM proliferation and involvement of cardiovascular system. There are a few studies to investigate noise-induced vascular changes using noninvasive methods. In this study we used carotid artery intima-media thickness (CIMT and aortic augmentation as indices of arterial properties and cystatin C as a serum biomarker relating to ECM metabolism. Materials and Methods: Ninety-three male participants were included in this study from aeronautic technicians: 39 with and 54 without a history of wide band noise (WBN exposure. For better discrimination, the participants were divided into the two age groups: 40 years old. Adjusted aortic augmentation index (AI for a heart rate equal to 75 beats per minute (AIx@HR75 were calculated using pulse wave analysis (PWA. CIMT was measured in 54 participants who accepted to undergo Doppler ultrasonography. Serum cystatin C was also measured. Results: Among younger individuals the mean CIMT was 0.85 ± 0.09 mm and 0.75 ± 0.22 mm in the in the exposed and the control groups respectively. Among older individuals CIMT had a mean of 1.04 ± 0.22 mm vs. 1.00 ± 0.25 mm for the exposed vs. the control group. However, in both age groups the difference was not significant at the 0.05 level. A comparison of AIx@HR75 between exposure group and control group both in younger age group (5.46 ± 11.22 vs. 8.56 ± 8.66 and older age group (17.55 ± 10.07 vs. 16.61 ± 5.77 revealed no significant difference. We did not find any significant correlation between CIMT and AIx@HR75 in exposed group (r = 0.314, P value = 0.145 but the correlation was significant in control group (r = 0.455, P value = 0.019. Serum cystatin C level was significantly lower in individuals with WBN exposure compared to controls (441.10 ± 104.70 ng/L vs. 616.89 ± 136.14, P

    In this work, we have evaluated the possibility of applying the Monte Carlo simulation technique in photon dosimetry of external individual monitoring. The GEANT4 toolkit was employed to simulate experiments with radiation monitors containing TLD-100 and CaF{sub 2}:NaCl thermoluminescent detectors. As a first step, X ray spectra were generated impinging electrons on a tungsten target. Then, the produced photon beam was filtered in a beryllium window and additional filters to obtain the radiation with desired qualities. This procedure, used to simulate radiation fields produced by a X ray tube, was validated by comparing characteristics such as half value layer, which was also experimentally measured, mean photon energy and the spectral resolution of simulated spectra with that of reference spectra established by international standards. In the construction of thermoluminescent dosimeter, two approaches for improvements have. been introduced. The first one was the inclusion of 6% of air in the composition of the CaF{sub 2}:NaCl detector due to the difference between measured and calculated values of its density. Also, comparison between simulated and experimental results showed that the self-attenuation of emitted light in the readout process of the fluorite dosimeter must be taken into account. Then, in the second approach, the light attenuation coefficient of CaF{sub 2}:NaCl compound estimated by simulation to be 2,20(25) mm{sup -1} was introduced. Conversion coefficients C{sub p} from air kerma to personal dose equivalent were calculated using a slab water phantom with polymethyl-metacrilate (PMMA) walls, for reference narrow and wide X ray spectrum series [ISO 4037-1], and also for the wide spectra implanted and used in routine at Laboratorio de Dosimetria. Simulations of backscattered radiations by PMMA slab water phantom and slab phantom of ICRU tissue-equivalent material produced very similar results. Therefore, the PMMA slab water phantom that can be easily

    Although externalizing behavior problems show in general a high stability over time, the course of externalizing behavior problems may vary from individual to individual. Our main goal was to investigate the predictive role of parenting on externalizing behavior problems. In addition, we investigated the potential moderating role of gender and genetic risk (operationalized as familial loading of externalizing behavior problems (FLE), and presence or absence of the dopamine receptor D4 (DRD4) 7-repeat and 4-repeat allele, respectively). Perceived parenting (rejection, emotional warmth, and overprotection) and FLE were assessed in a population-based sample of 1768 10- to 12-year-old adolescents. Externalizing behavior problems were assessed at the same age and 212 years later by parent report (CBCL) and self-report (YSR). DNA was extracted from blood samples. Parental emotional warmth predicted lower, and parental overprotection and rejection predicted higher levels of externalizing behavior problems. Whereas none of the parenting factors interacted with gender and the DRD4 7-repeat allele, we did find interaction effects with FLE and the DRD4 4-repeat allele. That is, the predictive effect of parental rejection was only observed in adolescents from low FLE families and the predictive effect of parental overprotection was stronger in adolescents not carrying the DRD4 4-repeat allele.

    An analysis is described for predicting the consequences of a reduction in the administratively applied maximum dose equivalent level to individuals in a group of workers occupationally exposed to ionising radiations, for the situation in which no changes are made to the working environment. This limitation of the maximum individual dose equivalent is accommodated by allowing the number of individuals in the working group to increase. The derivation of the analysis is given, together with worked examples, which highlight the important assumptions that have been made and the conclusions that can be drawn. The results are obtained in the form of the capacity of the particular working environment to accommodate the limitation of the maximum individual dose equivalent, the increase in the number of workers required to carry out the productive work and any consequent increase in the occupational collective dose equivalent.

    Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter ‘D-shuttle’ for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

    This paper estimates the occupational effective dose and the relative risk of leukemia and cancers of the digestive tract mortality through dose study of the most radiosensitive anatomical regions (lens, thyroid, chest and gonads) of the professionals involved in interventional gonad procedures. It was considered a cumulative exposure time of 10,000 hours, which is the occupational exposure time of an IOE in throughout his professional life. It was also considered that they always use Personal Protective Equipment (PPE). Mathematical models derived from epidemiological data contained in the BEIR V and in the IAEA’s TECDOC 870 are used to estimate the relative risk. The results show a significant increase in mortality risk for these types of cancer for individuals occupationally exposed to three different distances from the x-ray beam, and reinforces that radiation protection measures are essential.

    The single radiological surveillance of the occupational exposure to external radiation sources in Cuba it is carried out by the Radiation Protection and Hygiene Center (CPHR). The data corresponding to the external exposure are presented. The service it covers to all the occupationally exposed workers (TOEs) of the country that work fundamentally the radiodiagnostic practices, nuclear medicine, radiotherapy and research. The purpose of this work is to carry out an analysis of the occupational exposures of the TOE of the country starting of the results registered by the service of single radiological surveillance in the period 2001 to 2005, keeping in mind the indicators used by the UNSCEAR. The annual average effective dose (E) for each practice is shown. The obtained results showed that the values of annual average effective dose (E) its are bigger for the radiodiagnostic practices, radiotherapy and nuclear medicine. In a general way, all the E values are inferior to 2.00 mSv. The number of TOEs that overcame the 20 mSv established as annual dose limit, it went inferior to 1% of the controlled total universe.

    Occupational therapists and other allied health professionals face diversity with their clients, including sexual orientation. The purpose of this study was to determine the preparedness and comfort level of occupational therapy practitioners in working with gay, lesbian, and bisexual clients. A 23-item survey was mailed to 1,051 practitioners in a midwestern state. Eighty-eight were undeliverable and 373 usable surveys were returned, yielding a 39% response rate. Most respondents felt prepared and comfortable to work with clients who are gay, lesbian, or bisexual, and 48% agreed that sexuality influences occupational choices. Twenty-nine percent agreed that sexual orientation influences occupational therapy treatment. Less than 20% of the respondents, however, received education and used inclusive language in their documentation, and only 14% reported having resources and support services for clients who are gay, lesbian, or bisexual. Effective education and policy-making strategies are necessary to ensure an accepting therapeutic environment and respect for the role of sexual orientation in the intervention process.

    Relationship between occupational exposure to lead and frequency of complications in persons with arterial hypertension has been poorly investigated. This study aimed at evaluation of the relationship between occupational exposure to lead and manifestation of an increased local arterial stiffness and left ventricular diastolic dysfunction. The studies included 105 men (mean age: 44.47 ± 9.12 years) with arterial hypertension, treated with hypotensive drugs: group I - men occupationally exposed to lead (n = 53), and group II - men not exposed to lead (n = 52). In echocardiographic examination, the left ventricular diastolic dysfunction was diagnosed significantly more frequently in group I than in group II. In eTracking examination mean values of stiffness parameter (β), augmentation index (AI) and one-point pulse wave velocity (PWV-β) were significantly higher and mean values of arterial compliance (AC) were significantly lower in group I than in group II. The logistic regression showed that in the group of persons with arterial hypertension occupationally exposed to lead a more advanced age, higher blood lead concentration and higher mean values of augmentation index represent independent risk factors of left ventricular diastolic dysfunction. The multifactorial regression showed that amongst persons with arterial hypertension occupationally exposed to lead higher blood zinc protoporphyrin concentration, a more advanced age and higher value of body mass index (BMI) represent independent risk factors of an increased local arterial stiffness. In summary, we should note that in the group of persons with arterial hypertension occupationally exposed to lead the study has demonstrated a significantly more frequent manifestation of left ventricular diastolic dysfunction and an increase in local arterial stiffness. - Highlights: → Amongst persons with AH exposed to Pb higher ZnPP represent independent risk factor of increased local arterial stiffness. → Higher Pb

    To externally validate previously published predictive models of the risk of developing metachronous peritoneal carcinomatosis (PC) after resection of nonmetastatic colon or rectal cancer and to update the predictive model for colon cancer by adding new prognostic predictors. Data from all patients with Stage I-III colorectal cancer identified from a population-based database in Stockholm between 2008 and 2010 were used. We assessed the concordance between the predicted and observed probabilities of PC and utilized proportional-hazard regression to update the predictive model for colon cancer. When applied to the new validation dataset (n = 2011), the colon and rectal cancer risk-score models predicted metachronous PC with a concordance index of 79% and 67%, respectively. After adding the subclasses of pT3 and pT4 stage and mucinous tumour to the colon cancer model, the concordance index increased to 82%. In validation of external and recent cohorts, the predictive accuracy was strong in colon cancer and moderate in rectal cancer patients. The model can be used to identify high-risk patients for planned second-look laparoscopy/laparotomy for possible subsequent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

    The aim of this study was to quantify and predict relationships between rating of perceived exertion (RPE) and GPS training-load (TL) variables in professional Australian football (AF) players using group and individualized modeling approaches. TL data (GPS and RPE) for 41 professional AF players were obtained over a period of 27 wk. A total of 2711 training observations were analyzed with a total of 66 ± 13 sessions/player (range 39-89). Separate generalized estimating equations (GEEs) and artificial-neural-network analyses (ANNs) were conducted to determine the ability to predict RPE from TL variables (ie, session distance, high-speed running [HSR], HSR %, m/min) on a group and individual basis. Prediction error for the individualized ANN (root-mean-square error [RMSE] 1.24 ± 0.41) was lower than the group ANN (RMSE 1.42 ± 0.44), individualized GEE (RMSE 1.58 ± 0.41), and group GEE (RMSE 1.85 ± 0.49). Both the GEE and ANN models determined session distance as the most important predictor of RPE. Furthermore, importance plots generated from the ANN revealed session distance as most predictive of RPE in 36 of the 41 players, whereas HSR was predictive of RPE in just 3 players and m/min was predictive of RPE in just 2 players. This study demonstrates that machine learning approaches may outperform more traditional methodologies with respect to predicting athlete responses to TL. These approaches enable further individualization of load monitoring, leading to more accurate training prescription and evaluation.

    Although the benefits of a range of disability-centric therapies have been well studied, little remains known about how they work, let alone how to monitor these benefits in a precise and reliable way. Here, in two independent studies, we examine how sessions consisting of occupational or music therapy, both widely recognised for their effectiveness, modulate levels of salivary α-amylase (sAA), a now time- and cost-efficient marker of stress, in individuals with intellectual disability and autism spectrum disorder. Pre-session and post-session levels of sAA were compared in both groups in response to therapy and control sessions. In comparison to control sessions, occupational therapy significantly dampened rises in sAA levels while music therapy significantly decreased baseline sAA levels, highlighting the ability of both types of therapy to reduce stress and by proxy contribute to enhancing overall well-being. Not only do these results confirm the stress-reducing nature of two types of multisensory therapy, but they support the use of sAA as a potential tool for evaluating stress levels in individuals with intellectual disability and autism spectrum disorder, providing an important physiological lens that may guide strategies in clinical and non-clinical care for individuals with disabilities. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

  5. [An analysis of the effectiveness of external quality assurance programmes using changes in quality indicators of individual hospitals].

    Lack, Nicholas; Gerhardinger, Ursula

    2010-01-01

    Judging the effectiveness of external quality assurance programmes by comparing current performance with unadjusted regional or national crude averages is misleading because the influence of the actual size of the populations under consideration as well as the variance of performance between hospitals is underestimated. Not only do these artefacts lead to a general overestimation of changes in regional averages. They also may lead to a ranking confounded by regional size. An assessment at unit level circumvents these difficulties. The differential grading of degree of departure of a unit's performance from national targets available from funnel plots allows, in addition, for the discrimination between effects due to the monitoring institution and achievements attributable to the hospital under surveillance.

    Full Text Available We reanalyzed previous data to develop a more simplified decision tree model as a screening tool for unrecognized diabetes, using basic information in Beijing community health records. Then, the model was validated in another rural town. Only three non-laboratory-based risk factors (age, BMI, and presence of hypertension with fewer branches were used in the new model. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve (AUC for detecting diabetes were calculated. The AUC values in internal and external validation groups were 0.708 and 0.629, respectively. Subjects with high risk of diabetes had significantly higher HOMA-IR, but no significant difference in HOMA-B was observed. This simple tool will help general practitioners and residents assess the risk of diabetes quickly and easily. This study also validates the strong associations of insulin resistance and early stage of diabetes, suggesting that more attention should be paid to the current model in rural Chinese adult populations.

    Full Text Available Parkinson’s Disease (PD is a neurodegenerative disorder that has received considerable attention in allopathic medicine over the past decades. However, it is clear that, to date, pharmacological and surgical interventions do not fully address symptoms of PD and patients’ quality of life. As both an alternative therapy and as an adjuvant to conventional approaches, several types of rhythmic movement (e.g., movement strategies, dance, tandem biking, tai chi have shown improvements to motor symptoms, lower limb control and postural stability in people with PD (Amano, Nocera, Vallabhajosula, Juncos, Gregor, Waddell et al., 2013; Earhart, 2009; M. E. Hackney & Earhart, 2008; Kadivar, Corcos, Foto, & Hondzinski, 2011; Morris, Iansek, & Kirkwood, 2009; Ridgel, Vitek, & Alberts, 2009. However, while these programs are increasing in number, still little is known about the neural mechanisms underlying motor improvements attained with such interventions. Studying limb motor control under task specific contexts can help determine the mechanisms of rehabilitation effectiveness. Both internally guided (IG and externally guided (EG movement strategies have evidence to support their use in rehabilitative programs. However, there appears to be a degree of differentiation in the neural substrates involved in IG versus EG designs. Because of the potential task specific benefits of rhythmic training within a rehabilitative context, this report will consider the use of IG and EG movement strategies, and observations produced by functional magnetic resonance imaging (fMRI and other imaging techniques. This review will present findings from lower limb imaging studies, under IG and EG conditions for populations with and without movement disorders. We will discuss how these studies might inform movement disorders rehabilitation (in the form of rhythmic, music-based movement training and highlight research gaps. We believe better understanding of lower limb neural

    Full Text Available This article examines the inefficient use of resources in the Brazilian transportation system. The energy use growth and external cost generation in this essential economic sector are considerable, and the trend is towards an increasing problem in the coming years. The continued expansion of Brazilian cities and the increase in demand for mobility is a result of a substantial growth in the number of road transport users, as increased earnings enable lower income groups to acquire and use individual motorized means of transport. The aim of this paper is to estimate the potential gains from reducing individual motorized transport by the year 2020. This investigation concludes that in a conservationist scenario, by prioritizing low cost, low technology public policies—which include operation of Bus Rapid Transit systems, walking and cycling facilities and congestion charges, among others—it should be possible to save over USD 30 billion and USD 26 billion in external transportation and infrastructure costs, respectively, up to 2020. In addition, these public policies can save more than 35 million Tons of Oil Equivalents in energy consumption and avoid almost 4,000 thousand tons of local pollution emissions and 37,500 thousand tons of GHG emissions in the same period.

    Despite of the widepread use of Pilates in Physical Therapy, there are few studies that have assessed the muscle electrical activation during Pilates exercises. Verify the influence of different spring adjustments and individual positions on the electrical activation of multifidus (MU) and oblique external (OE) muscles during hip flexion-extension (HFE) exercise on the Cadillac. Eight women practicing Pilates exercises for at least six months performed 10 repetitions of HFE in the following situations: Lower Spring, spring fixed at 30 cm in relation to level which the individuals were positioned. Higher Spring, spring fixed at 90 cm in relation to level which the individuals were positioned. Near Position, distance of 10 cm from the fixed spring. Distant Position, distance of 30 cm from the fixed spring. Kinematic and eletromyographic data (EMG) were collected simultaneously and the MU and OE muscles were monitored. Each movement of HFE was splitted in two phases (extension and flexion). The EMG signal was calculated and normalized using the maximal voluntary contraction (MVC). The Wilcoxon test was used to investigate differences between the situations (p MVC, and the highest muscle activation in the lower spring and in the near position. OE muscles presented muscle activation values ranging from 20 to 45% MVC, and the highest values in the higher spring and in the distant position. MU and OE muscles presented a distinct electrical activation during different available spring adjustments and individual positions.

    After the Fukushima Dai-ichi Nuclear Power Plant accident, the Fukushima Health Management Survey (FHMS) was launched. The Basic Survey, a component of FHMS, is a questionnaire used to survey residents across the Fukushima Prefecture about their behaviour in the first 4 months after the accident. The questionnaire findings are used to determine individual external doses by linking behaviour data to a computer programme with daily gamma ray dose rate maps, drawn after the accident. Through 30 June 2015, the response rate was only 27.2% (558 550 population), indicating that the findings might not be generalisable because of poor representativeness of the population. The objective of this study was to clarify if the data from the FHMS Basic Survey were representative of the entire population, by conducting a new survey to compare the external doses between non-respondents and respondents in the previous survey. A total of 5350 subjects were randomly selected from 7 local regions of Fukushima Prefecture. An interview survey was conducted with the non-respondents to the FHMS Basic Survey. A total of 990 responses were obtained from the previous non-responders by interview survey. For the regions Kempoku, Kenchu, Kennan, Aizu, Minami-Aizu, Soso, and Iwaki, differences in mean effective dose (95% confidence interval) in mSv between the non-responders and previous responders were 0.12 (0.01-0.23), -0.09 (-0.21-0.03), -0.06 (-0.18-0.07), 0.05 (-0.04-0.14), 0.01 (-0.01-0.02), 0.09 (0.01-0.17), 0.09 (0.00-0.17), respectively. The differences fall neither within the interval (-∞, -0.25) nor within the interval (0.25, ∞). These findings imply that mean effective doses between the previous and new respondents were not different, with a significantly indifferent region of 0.25 mSv according to equivalence tests. The present study indicates that the dose distribution obtained from about one-quarter of Fukushima residents represents the dose distribution for the entire

    We described an individualized occupational therapy (IOT) programme and examined the effects of adding IOT to group OT (GOT) on improving neurocognition, symptoms and social functioning among recently hospitalized patients with schizophrenia. The Brief Assessment of Cognition in Schizophrenia-Japanese version (BACS-J), the Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning scale were used for outcome evaluations. Fifty-one patients were voluntarily assigned to either the GOT + IOT (n = 30) or GOT alone (n = 21) groups based on their preferences. Retention in the GOT + IOT group was 100%. Three-month baseline to discharge assessments in the GOT + IOT group showed significant improvements in BACS-J verbal memory, working memory, verbal fluency, attention, executive function and composite score, and in PANSS positive subscale, general psychopathology subscale, and total score compared to the GOT alone group. Study limitations notwithstanding, the present findings provide preliminary support for the feasibility of implementing IOT and its effectiveness for improving cognitive impairment and symptoms in patients with schizophrenia. The results of this study indicate that IOT in psychiatric facilities may improve psychosocial treatment of schizophrenia. Additional study is warranted to replicate the effects of IOT as demonstrated in this Japanese study. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    This work aims to develop and establish a methodology for in vivo internal monitoring at individuals occupationally exposed (IOE) to F-18 in form of F-18DG at the DIPRA/CRCN-NE. The detection system used was the NaI(Tl) 3' x 3', coupled with the software Genie 2000. The measurements performed with the brain phantom were used to obtain the Calibration Factor. The bioassay data interpretation was performed through software AIDE, using the F-18DG biokinetic model available in ICRP 53 publication. The MDED obtained was compared to the value of the recording level, 1 mSv, recommended by IAEA in order to validate the technique. During two days of F-18DG productions, there were performed in vivo measurements of the IOE at DIPRA/CRCN-NE. The methodology developed demonstrated sufficient sensitivity for detect MDED of 76 n Sv. The results of the in vivo measurements demonstrated that all IOE from CRCN/NE obtained doses below MDED. (author)

    Why, more than 20 years ago, did there emerge the need for an International System on Occupational Exposure (ISOE)? How was it created? What were the problems and their possible solutions? Who were the main stakeholders? These are a few of the questions that the ISOE NEA Secretariat and Bureau asked Christian Lefaure, ex CEPN Deputy Director, to address in preparing a report on the history of ISOE and its progress. He had been directly involved in the brainstorming that preceded ISOE establishment, and he became the first head of the ISOE European Technical Centre, in charge of the world database development and management from 1991 to 2007. For writing this report, he made use of his own souvenirs and documentation as well as of those of tens of ISOE participants, both from major international and regional organisations (OECD/NEA, IAEA, EC and BNL), nuclear power plant utilities and national regulatory authorities. He voluntarily focused not only on the technical aspects but also on the human components of that story. This was done through personal interviews with many individuals who have played an important role at one moment of ISOE life, the analysis of answers to a questionnaire, and reviews of the minutes of many ISOE meetings that were held before and after the official establishment of the ISOE, along its lifespan to date. The most important inputs were the accounts from many individuals having very actively participated in the ISOE life at one step or another. The contacts were not always easy to make 15 or 20 years later. But in general, the questions were welcomed and the answers to the interviews and to a short questionnaire have fed this report. More than 50 individuals have answered these requests one way or another. Some have followed ISOE birth and premises; some have not seen the first steps of ISOE but have participated later on or are still participating. Some have been able to provide pictures, drawings or relevant publications. All their

    After the Fukushima Daiichi nuclear power plant accident, the air dose gradually decreases every year due to the physical decay of radioactive materials and environmental changes as well as countermeasures. However, there is little information on personal behavioral patterns and individual dose from external exposure among the inhabitants around the nuclear power plant. To evaluate the dose from external exposure in Minamisoma city and compare the differences with outside of Fukushima, we started the external dose assessment project in cooperation with city officials in Minamisoma as well as other three cities in Japan, where the natural terrestrial background radiation level is relatively high. In these four cities, external dose was measured using the D-shuttle for 2 weeks, and the places of activity of participants were recorded every hour to compare and evaluate the dose from external exposure and to clarify whether there is a difference in the exposure dose by behavior. The annual doses from external exposure for 100 participants from four municipalities ranged from 0.566 to 1.295 with a mean value of 0.784 mSv/year, which was sufficiently low for health effects. The external doses in Minamisoma city were comparable to those in municipalities with a relatively high natural radiation background in Japan. The time spent at home and in the workplace accounted for most of the time of the participants, and this also contributed to majority of the total dose from external exposure. The amount of exposure at times other than home and workplace was very small regardless of the indoor or outdoor location in the city or outside. Continuous dosimetry and countermeasures at home and workplace are important for individuals who present high values, for future dose reduction and radiation protection. . © 2017 IOP Publishing Ltd.

    Personnel monitoring is a key step in radiation protection programme. It helps in keeping a check on radiation hazards and safety aspects of the operating unit. Moreover, analysis of the temporal trends in exposure histories of the individuals/groups play an important role in assessing the need of improved standards of protection and the impact of implementation of such measures. The paper presents the analysis of annual effective dose and collective dose to the radiation workers, which are indicators of individual risk and the impact of the practice. The present study also gives the analysis of the effective dose, cumulative dose and various dose distribution ratios (SR E and NR E ) for the block of 5 years (2000-2004) of RAPS 1 and 2 the oldest PHWR in the country and RAPS 3 and 4 the latest in the series incorporating many improvements in design and operation. It is seen that occupational exposures at NPPs have been showing a steadily decreasing trend, which is a result of a number of design improvements, operation and protection measures. However, to achieve world standards, we have to go a long way by further carrying out identification of areas of improvement, good operating practices along with the desired modifications in design.

    In Japan, Rokkasho Reprocessing Plant (RRP) is going to start the operation in service as the first large-scale commercial reprocessing plant of spent fuels that has annual reprocessing quantity of 800tU pr in maximum. The occupational external exposure is controlled for the purpose of keeping dose as low as reasonably achievable, and it is monitored by the personal dosimeter. On the other hand, the occupational internal exposure is controlled for the purpose of preventing, and it is monitored by the periodical evaluation of internal dose from the radioactive concentration in air of workplace. The individual doses of radiation workers are less than the dose limits in the statute and our lower management values enough. Dose data will be stored continuously and the rational management method will be examined. (author)

    After the 2011 Fukushima Daiichi nuclear power plant accident, little information has been available on individual doses from external exposure among residents living in radioactively contaminated areas near the nuclear plant; in the present study we evaluated yearly changes in the doses from external exposure after the accident and the effects of decontamination on external exposure. This study considered all children less than 16 years of age in Soma City, Fukushima who participated in annual voluntary external exposure screening programs during the five years after the accident (n = 5,363). In total, 14,405 screening results were collected. The median participant age was eight years. The geometric mean levels of annual additional doses from external exposure attributable to the Fukushima accident, decreased each year: 0.60 mSv (range: not detectable (ND)-4.29 mSv), 0.37 mSv (range: ND-3.61 mSv), 0.22 mSv (range: ND-1.44 mSv), 0.20 mSv (range: ND-1.87 mSv), and 0.17 mSv (range: ND-0.85 mSv) in 2011, 2012, 2013, 2014, and 2015, respectively. The proportion of residents with annual additional doses from external exposure of more than 1 mSv dropped from 15.6% in 2011 to zero in 2015. Doses from external exposure decreased more rapidly than those estimated from only physical decay, even in areas without decontamination (which were halved in 395 days from November 15, 2011), presumably due to the weathering effects. While the ratios of geometric mean doses immediately after decontamination to before were slightly lower than those during the same time in areas without decontamination, annual additional doses reduced by decontamination were small (0.04-0.24 mSv in the year of immediately after decontamination was completed). The results of this study showed that the levels of external exposure among Soma residents less than 16 years of age decreased during the five years after the Fukushima Daiichi nuclear power plant accident.

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

    The Occupational Safety and Health Act of 1970 and the Workers Right to Know laws later in that decade were signature moments in the history of occupational safety and health. We have examined how and why industry leaders came to accept that it was the obligation of business to provide information about the dangers to health of the materials that workers encountered. Informing workers about the hazards of the job had plagued labor-management relations and fed labor disputes, strikes, and even pitched battles during the turn of the century decades. Industry's rhetorical embrace of the responsibility to inform was part of its argument that government regulation of the workplace was not necessary because private corporations were doing it.

    Full Text Available Occupational therapists have always been dedicated to the human occupation study, however the client hasn’t always been seen as an occupational being, with needs, interests and individual goals. The concern for our clients’ engagement in occupation, rather than the acquisition or restoration of performance components, together with the gradual modification of the concept of occupation from work-related activities to purposeful human activity, requires a broadening of our scope of practice. The most current theories related to occupational therapy practice have highlightes the use of client centered and occupational based practices. In occupation-based, client-centred practice the client participates actively in negotiating goals, and client occupational goals are given priority and are placed at the centre of assessment, intervention and outcomes. There are numerous evidences in the literature with significantly positive results supporting these approaches. These approaches are based on the premises that goals and objectives of interventions should be focused in occupation and significant activities to the client and reflect the occupational therapy core values: an occupational-centred perspective that respects client’s choices, goals and values, promoting and supporting the engagement on meaningful activities.

    in the cases of electricity generation and transportation, where accidental situations are evaluated. The impacts of construction and decommissioning of a facility are included in the electricity generation stage. It is important to stress that this methodology does not employ a worst case scenario analysis, as is usually done for safety or regulatory compliance assessments, but intends to evaluate the impacts expected from the operations. In a few cases, however, when no reasonable alternative seemed possible, conservative values were used. The impact pathway approach requires an inventory and assessment of all potential impacts, however, within the context of the ExternE project it has not been possible to consider all of these. Therefore, only the most important impacts, called priority impacts, have been included. Releases of radioactive material to the environment, which potentially impact public health, were given the highest priority. Occupational health impacts, from both radiological and nonradiological causes, were the next priority, even though the extent to which occupational health impacts can be considered as externalities has not yet been addressed

    Full Text Available This study investigated the relationship between feedback processing and antisocial personality traits measured by the PSSI questionnaire (Kuhl & Kazén, 1997 in a healthy undergraduate sample. While event-related potentials (Feedback Related Negativity [FRN], P300 were recorded, participants encountered expected and unexpected feedback during a gambling task. As recent findings suggest learning problems and deficiencies during feedback processing in clinical populations of antisocial individuals, we performed two experiments with different healthy participants in which feedback about monetary gains or losses consisted either of social-emotional (facial emotion displays or non-social cues (numerical stimuli. Since the FRN and P300 are both sensitive to different aspects of feedback processing we hypothesized that they might help to differentiate between individuals scoring high and low on an antisocial trait measure.In line with previous evidence FRN amplitudes were enhanced after negative and after unexpected feedback stimuli. Crucially, participants scoring high on antisocial traits displayed larger FRN amplitudes than those scoring low only in response to expected and unexpected negative numerical feedback, but not in response to social-emotional feedback - irrespective of expectancy. P300 amplitudes were not modulated by antisocial traits at all, but by subjective reward probabilities. The present findings indicate that individuals scoring high on antisociality attribute higher motivational salience to monetary compared to emotional-social feedback which is reflected in FRN amplitude enhancement. Contrary to recent findings, however, no processing deficiencies concerning social-emotional feedback stimuli were apparent in those individuals. This indicates that stimulus salience is an important aspect in learning and feedback processes in individuals with antisocial traits which has potential implications for therapeutic interventions in

    Occupational rhinitis (OR) involves nasal congestion, rhinorrhea, nasal itching, and/or sneezing resulting from workplace exposures. OR can have a significant negative effect on quality of life and productivity. OR can be divided into allergic or nonallergic subgroups based on the underlying pathogenesis. Certain occupational exposures place employees at greater risk for developing disease. Primary treatment is avoidance of implicated exposures. Antihistamines, saline rinses, and nasal steroids may be useful. OR can coexist with occupational asthma, and rhinitis symptoms have been reported to precede those of the lower respiratory tract. OR is has both medical and socioeconomic implications. Copyright © 2016 Elsevier Inc. All rights reserved.

    The performance of activities of daily living (ADL) at home is important for the recovery of older individuals after hip fracture. However, 20-90% of these individuals lose ADL function and never fully recover. It is currently unknown to what extent occupational therapy (OT) with coaching based on cognitive behavioral treatment (CBT) improves recovery. The same holds for sensor monitoring-based coaching in addition to OT. Here, we describe the design of a study investigating the effect of sensor monitoring embedded in an OT rehabilitation program on the recovery of ADL among older individuals after hip fracture. Six nursing homes will be randomized in a three-arm stepped wedge cluster randomized trial. All nursing homes will initially provide standard care. At designated time points, nursing homes, successively and in random order, will cross over to the provision of OT and at the next time point, to sensor monitoring-enhanced OT. A total of 288 older individuals, previously living alone in the community, who after a hip fracture were admitted to a geriatric rehabilitation ward for a short-term rehabilitation, will be enrolled. Individuals in the first intervention group (OTc) will participate in an OT rehabilitation program with coaching based on cognitive behavioral therapy (CBT) principles. In the sensor monitoring group, sensor monitoring is added to the OT intervention (OTcsm). Participants will receive a sensor monitoring system consisting of (i) an activity monitor during nursing home stay, (ii) a sensor monitoring system at home and a (iii) a web-based feedback application. These components will be embedded in the OT. The OT consists of a weekly session with an occupational therapist during the nursing home stay followed by four home visits and four telephone consultations. The primary outcome is patient-perceived daily functioning at 6 months, assessed using the Canadian Occupational Performance Measure (COPM). As far as we know, this study is the first

  7. Occupancy in continuous habitat

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

  9. Ancient DNA analysis might suggest external origin of individuals from chamber graves placed in medieval cemetery in Pień, Central Poland.

    The participation of immigrants during early days in Poland of Piast's dynasty is a debated issue among archaeologists and anthropologists alike. Such hypotheses were formulated on the basis of, amongst others, the discovery of early medieval chamber graves characterized by construction features typical of the Scandinavian culture area. Archaeological and anthropological studies to date have not provided an unequivocal answer as to whether the individuals interred in those graves were autochthons who adopted a different burial rite, or perhaps immigrants from foreign lands. To characterize the gene pool of this population we analyzed the C/T allele of the nuclear gene LCT-13910 as well as fragments of the mitochondrial genome from individuals buried in very richly furnished chamber graves at the medieval cemetery in Pień. The obtained results for the nuclear allele and mtDNA do not corroborate the Scandinavian origin of the analyzed population. Moreover, we did not find haplogroup I, which is the one typical of populations that historically inhabited the north of Europe; and the frequency of the LCT-13910 T allele was similar to that of past and present Polish populations. On the other hand, we identified the atypical haplogroup C5c1, which suggests Asian origin of the studied individuals and confirms our previous reports concerning ancient human migrations from Asia to the territory of present-day Poland. While our findings do not conclusively disprove a Scandinavian lineage of the studied population, they certainly shed some new light on the origin of the individuals buried in chamber graves, which may be very different from the one initially proposed by archaeologists.

    A nuclear explosion has the potential to injure or kill tens to hundreds of thousands of people through exposure to fallout (external gamma) radiation. Existing buildings can protect their occupants (reducing external radiation exposures) by placing material and distance between fallout particles and indoor individuals. This protection is not well captured in current fallout risk assessment models and so the US Department of Defense is implementing the Regional Shelter Analysis methodology to improve the ability of the Hazard Prediction and Assessment Capability (HPAC) model to account for building protection. This report supports the HPAC improvement effort by identifying a set of building attributes (next page) that, when collectively specified, are sufficient to calculate reasonably accurate, i.e., within a factor of 2, fallout shelter quality estimates for many individual buildings. The set of building attributes were determined by first identifying the key physics controlling building protection from fallout radiation and then assessing which building attributes are relevant to the identified physics. This approach was evaluated by developing a screening model (PFscreen) based on the identified physics and comparing the screening model results against the set of existing independent experimental, theoretical, and modeled building protection estimates. In the interests of transparency, we have developed a benchmark dataset containing (a) most of the relevant primary experimental data published by prior generations of fallout protection scientists as well as (b) the screening model results.

    As a result of progressive shortening and orogenic wedge thickening, marine foreland basins tend to emerge and divide. We have analyzed possible recent tectonic activity within the late evolution stage of the Ronda basin, an intermontane basin located in the external wedge of the Gibraltar Arc, formerly connected with the Betic foreland basin and infilled by marine Upper-Miocene sediments. We analyze (1) the structures responsible for the basinward relief drop along the arc strike and the different topography of their boundaries; (2) qualitative and quantitative geomorphologic indices to asses which structures could present recent activity; and 3) the structures causing the division of the former Betic foreland basin and the isolation of the Ronda basin. Within the deformational history of the Ronda basin, late structures that control high topographic gradients and generate remarkable fault scarps group into three main types: (a) Extensional structures represented by NW-SE striking normal faults, clustered close to the current SW and NE boundaries of the basin. They usually dip towards the basin and their vertical displacement is maximum up to 1,5 km. These structures partially affect the basal unconformity of the Upper Miocene basin infill and are scarcely developed inside the basin infill. (b) Shortening structures developed both in the basin infill and in the outcropping basement near the Northeastern and Southwestern basin boundaries. They are represented by NE-SW directed plurikilometric box-folds and reverse faults, responsible for the alternation of sierras (altitudes 1000-1500 m) and valleys. (c) Strike-slip dominated structural associations where WSW-ENE lateral faults combined with folds and normal and reverse faults defined a NE-SW directed deformation band constituting the NW basin boundary. This band includes some sierras up to 1.100 m. Regarding the relief of the Ronda basin area, the abrupt slopes of the outcropping basement (heights between 500

    2016-01-01

    The aim of this review was to summarize the current state of knowledge on heat stress risk within typical Australian occupational settings. We assessed identified occupations (mining, agriculture, construction, emergency services) for heat production and heat loss potential, and resultant levels of physiological heat strain. A total of 29 reports were identified that assessed in-situ work settings in Northern Territory, South Australia, Western Australia, Queensland, New South Wales and Victoria, that measured physiological responses and characterized the thermal environment. Despite workers across all industries being regularly exposed to high ambient temperatures (32-42°C) often coupled with high absolute humidity (max: 33 hPa), physiological strain is generally low in terms of core temperature (demands of many tasks, and self-regulated pacing of work possible in most jobs. Heat stress risk is higher in specific jobs in agriculture (e.g. sheep shearing), deep underground mining, and emergency services (e.g., search/rescue and bushfire fighting). Heat strain was greatest in military-related activities, particularly externally-paced marching with carried loads which resulted in core temperatures often exceeding 39.5°C despite being carried out in cooler environments. The principal driver of core temperature elevations in most jobs is the rate of metabolic heat production. A standardized approach to evaluating the risk of occupational heat strain in Australian workplaces is recommended defining the individual parameters that alter human heat balance. Future research should also more closely examine female workers and occupational activities within the forestry and agriculture/horticulture sector.

    External exposure pathways were investigated in 1989, along the coastline from Rockcliffe in north Cumbria to the River Mersey. The survey involved four main periods of field work, when individuals and representatives of organisations were interviewed to establish time spent in recreational and occupational activities over intertidal areas. Data on seafood consumption rates were also collected. Gamma dose rate measurements were made to supplement routine monitoring operated by the Directorate of Fisheries Research. The critical group for external exposure was established as being those living on houseboats in the Ribble estuary. Their effective dose equivalent was assessed at 0.17 mSv in 1989, equivalent to an occupancy of 3000 h year 1 over unshielded mud. Succeeding high doses were found to be due to activities in the Wyre and Ravenglass estuaries and Whitehaven harbour. Locations where higher doses were found were few and far between and the majority of exposures were lower than 0.01 mSv. (author)

  4. Effects of divorce on Dutch boys' and girls' externalizing behavior in Gene × Environment perspective: diathesis stress or differential susceptibility in the Dutch Tracking Adolescents' Individual Lives Survey study?

    2012-08-01

    The effects of divorce on children's behavioral development have proven to be quite varied across studies, and most developmental and family scholars today appreciate the great heterogeneity in divorce effects. Thus, this inquiry sought to determine whether select dopaminergic genes previously associated with externalizing behavior and/or found to moderate diverse environmental effects (dopamine receptors D2 and D4, catechol-O-methyltransferase) might moderate divorce effects on adolescent self-reported externalizing problems; and, if so, whether evidence of gene-environment (G × E) interaction would prove consistent with diathesis-stress or differential-susceptibility models of environmental action. Data from the first and third wave of the Dutch Tracking Adolescents' Individual Lives Survey (n = 1,134) revealed some evidence of G × E interaction reflecting diathesis-stress but not differential susceptibility. It is intriguing that some evidence pointed to "vantage sensitivity," which are benefits accruing to those with a specific genotype when their parents remained together, the exact opposite of diathesis-stress. The limits of this work are considered, especially with regard to the conditions for testing differential susceptibility, and future directions are outlined.

    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.

  6. Occupation and the relevance of primatology to occupational therapy.

    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.

    Persons experiencing or at risk of homelessness have occupational needs that are seldom addressed in the Canadian system of care. The lack of documented evidence on occupational therapy practices in this field hinders the development of the profession. This article identifies current and potential practices that aim to enable or support the occupations of persons experiencing or at risk of homelessness. A scoping review was conducted, including evidence from both occupational therapy and non-occupational therapy sources. One hundred and seventy-eight papers were selected in the areas of occupational performance skills training, enrichment of occupational repertoire, employment/education, physical rehabilitation services, child/family services, community building, occupational transition from homeless to housed, literacy, and disaster relief. Occupational therapists can build environments and create opportunities that facilitate occupational engagement of individuals experiencing homelessness. Gaps in knowledge include the evaluation of occupational therapy practices, the Canadian context of family homelessness, and the cultural safety of occupational therapy interventions.

  10. Occupational dose constraint

    International Nuclear Information System (INIS)

    Heilbron Filho, Paulo Fernando Lavalle; Xavier, Ana Maria

    2005-01-01

    The revision process of the international radiological protection regulations has resulted in the adoption of new concepts, such as practice, intervention, avoidable and restriction of dose (dose constraint). The latter deserving of special mention since it may involve reducing a priori of the dose limits established both for the public and to individuals occupationally exposed, values that can be further reduced, depending on the application of the principle of optimization. This article aims to present, with clarity, from the criteria adopted to define dose constraint values to the public, a methodology to establish the dose constraint values for occupationally exposed individuals, as well as an example of the application of this methodology to the practice of industrial radiography

    2016-01-01

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

    The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for increased asthma severity. We retrospectively reviewed the clinical charts of 72 patients who received a diagnosis of allergic occupational asthma, with or without associated occupational rhinitis. Our findings suggested that persistent asthma tended to be more common in subjects with associated occupational asthma and rhinitis, and occupational asthma severity was associated with occupational rhinitis severity. Moderate-severe persistent occupational rhinitis is a risk factor for persistent occupational asthma. We demonstrated, for the first time in the occupational setting, a significant association between occupational rhinitis and asthma severity.

  15. A radiation protection training program designed to reduce occupational radiation dose to individuals using pneumatic-transfer systems at the Oregon State TRIGA reactor

    1984-01-01

    In order to keeping personnel doses as low as reasonably achievable, and also to help satisfy requirements of NRC regulations contained in 10 CFR 19, a training program was established to qualify all individuals prior to their use of the OSTR PT systems. Program objectives are directed mainly towards minimizing the spread of radioactive contamination and reducing the potential for unnecessary and inappropriate personnel radiation exposure; however, other operational and emergency procedures are also covered. The PT systems training program described in this report was established approximately 8 to 10 years ago but recently there was an increased interest to use it. Whether or not a PT system training program should be implemented at a specific TRIGA operation (assuming the facility is equipped with a PT system) will undoubtedly be influenced heavily by the nature and frequency of the PT system's use, by who uses the system, and by whether the system is one of the automatic loading and unloading types, or one of the more' commonly encountered manually operated systems. However, from our experience we feel that training commensurate with the type of PT system operation being conducted is a wise investment, and should be a requirement for all system operators

  1. The selection of occupancy factors

    International Nuclear Information System (INIS)

    Lakey, J.R.A.

    1977-01-01

    An estimate of the proportion of time that an area is occupied by radiation workers is often used in radiological protection to permit relaxation of exposure rate limits above those for continuous occupation. This proportion is known as an occupancy factor and is used most frequently in X-ray facilities. The strategy for controlling the external exposure of radiation workers must be decided before occupancy factors are selected for the design of the radiation protection facilities. When shielding has to be designed the occupancy factor effects the design objectives and permits increased exposure rates at the shield surface. It is useful to note that the selection of occupancy factors with due regard to the expected spatial variation of the exposure rate can help to reduce the range of the worker's radiation exposure because field gradients are usually steeper close to the shield. When other hazards, such as internal exposure, and other constraints, such as cost of the space consumed, are added, the selection of the optimum set of occupancy factors is more difficult. Two zone occupancy factors are discussed in this paper and proposals are made for a strategy to be used when there is more than one hazard and the designer has to meet constraints imposed by limitations of the facilities available. An important feature of the strategy is the avoidance of high radiation exposure to small groups of workers. The errors involved in assessment of the actual dose received by the radiation worker must be taken into account and in particular the selection of the higher exposure rate limits must be made with attention to the accident potential

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

    Full Text Available This paper focuses on occupational and public exposure during operation of disposal facilities receiving liquid and solid radioactive waste of various classes and provides a comparative analysis of the relevant doses: actual and calculated at the design stage. Occupational and public exposure study presented in this paper covers normal operations of a radioactive waste disposal facility receiving waste. Results: Analysis of individual and collective occupational doses was performed based on data collected during operation of near-surface disposal facilities for short-lived intermediate-, lowand very low-level waste in France, as well as nearsurface disposal facilities for long-lived waste in Russia. Further analysis of occupational and public doses calculated at the design stage was completed covering a near-surface disposal facility in Belgium and deep disposal facilities in the United Kingdom and the Nizhne-Kansk rock massive (Russia. The results show that engineering and technical solutions enable almost complete elimination of internal occupational exposure, whereas external exposure doses would fall within the range of values typical for a basic nuclear facility. Conclusion: radioactive waste disposal facilities being developed, constructed and operated meet the safety requirements effective in the Russian Federation and consistent with relevant international recommendations. It has been found that individual occupational exposure doses commensurate with those received by personnel of similar facilities abroad. Furthermore, according to the forecasts, mean individual doses for personnel during radioactive waste disposal would be an order of magnitude lower than the dose limit of 20 mSv/year. As for the public exposure, during normal operation, potential impact is virtually impossible by delaminating boundaries of a nuclear facility sanitary protection zone inside which the disposal facility is located and can be solely attributed to the use

  8. Dosimetry services for internal and external radiation sources

    International Nuclear Information System (INIS)

    1988-01-01

    The Canadian Atomic Energy Control Board (AECB) sets radiation dose limits for the operation of nuclear facilities and the possession of prescribed substances within Canada. To administer these regulations the AECB must be satisfied that the dosimetry services used by a licensee meet adequate standards. Licensees are required to use the Occupational Dosimetry Service operated by the Bureau of Radiation and Medical Devices, Department of National Health and Welfare (BRMD) to determine doses from external sources of radiation, except where a detailed rationale is given for using another service. No national dosimetry service exists for internal sources of radiation. Licensees who operate or use a dosimetry service other than the BRMD must provide the AECB with evidence of the competence of the staff and adequacy of the equipment, techniques and procedures; provide the AECB with evidence that a quality assurance program has been implemented; and send individual dose or exposure data to the National Dose Registry.

    2014-05-15

    We performed a study on the presence of chromosome aberrations in a cohort of plutonium workers of the Mayak production association (PA) with a mean age of 73.3 ± 7.2 years to see whether by multi-color fluorescence in situ hybridization (mFISH) translocation analysis can discriminate individuals who underwent occupational exposure with internal and/or external exposure to ionizing radiation 40 years ago. All Mayak PA workers were occupationally exposed to chronic internal alpha-radiation due to incorporated plutonium-239 and/or to external gamma-rays. First, we obtained the translocation yield in control individuals by mFISH to chromosome spreads of age-matched individuals and obtained background values that are similar to previously published values of an international study (Sigurdson et al. in Mutat Res 652:112-121, 2008). Workers who had absorbed a total dose of >0.5 Gy external gamma-rays to the red bone marrow (RBM) displayed a significantly higher frequency of stable chromosome aberrations relative to a group of workers exposed to <0.5 Gy gamma-rays total absorbed RBM dose. Thus, the translocation frequency may be considered to be a biological marker of external radiation exposure even years after the exposure. In a group of workers who were internally exposed and had incorporated plutonium-239 at a body burden >1.48 kBq, mFISH revealed a considerable number of cells with complex chromosomal rearrangements. Linear associations were observed for translocation yield with the absorbed RBM dose from external gamma-rays as well as for complex chromosomal rearrangements with the plutonium-239 body burden.

    2016-01-01

    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.

  12. Telephone chip-cards as individual dosemeters

    Goeksu, H.Y.

    2003-01-01

    It has been observed that a certain type of telephone chip-card can be used as radiation detectors for individuals exposed to external gamma doses. The radiation dose responses of more than 200 chip-cards, produced by various companies since 1990, were investigated using infrared stimulated luminescence (IRSL). The radiation dose responses of some of the chip-cards were found to be compatible with commonly used synthetic phosphors that are used for routine occupational dose monitoring. The IRSL signal is shown to be linear with a radiation dose from 250 mGy to 5 Gy and stable at ambient temperature, which allows the use of such chip-cards for reconstruction of doses for individuals

    According to studies by the Instituto Nacional do Cancer (INCA), in recent years the incidence of thyroid cancer is the fastest growing in relation to other types. For the treatment is required the exact amount of 131 I isotope for each patient resulting on manipulation of this isotope in nuclear medicine services by individuals who are considered occupationally exposed (OEI). This work aims to establish the methodology for calibration of the detection system used to determine the therapeutic activity of 131 I, required to release the desired absorbed dose in the thyroid gland, as well as in monitoring OEI that manipulate this radionuclide in nuclear medicine services. This is one of the early stages of implementation of Laboratorio de Dosimetria Interna at the Centro Regional de Ciencias Nucleares do Nordeste (CRCN-NE). The detector system consists of a NaI(Tl) 3'' x 3'' associated with electronic devices and Genie 2000 software. Sources of 60 Co, 137 Cs and 133 Ba were utilized for calibration. Firstly, measurements were carried out in non-exposed individuals for obtaining the Minimum Detectable Activity (MDA) and then Minimum Detectable Incorporation (MDI) and the Minimum Effective Dose Detectable (MEDD) were determined through biokinetic models provided by the ICRP 67 and edited by the AIDE software version 6 to workers and patients. The values for the MEDD were 3.57 x 10 -2 mSv, 5.56 x 10 -2 mSv and 10.7 x 10 -2 mSv to 1, 7 and 14 days, respectively, after 131 I incorporation by workers. As for patients, MEDD were 3.44 x 10 -2 mSv, 5.63 x 10 -2 mSv and 10.9 x 10 -2 mSv for the same periods of time. It is applicable to the assessment of dose OEI, since it presents less than the recommended minimum of 1 mSv. The technique also has adequate sensitivity for evaluation of activity present in the thyroid of patients with thyroid dysfunction. (author)

    To describe the follow-up of pregnancies at work and exposures to pregnancy occupational hazards. A cross-sectional study was performed between January and December 2014 in occupational health services of Languedoc-Roussillon region. Eligible workers were interviewed by occupational health physicians (OHPs) after delivery and at the time of returning to work (exposure, anticipation, prevention, communication, sick leave). Occupational skill levels were classified according to the French standard classification of occupations (version 2003) from the French National Institute of Statistics. Socioeconomic deprivation was assessed using the Evaluation of Deprivation and Inequalities in Health Examination (EPICES) individual scale. A total of 1347 workers were recruited. The mean age was at 30.7±4.5 years. Among pregnant workers, there were 54.2% of employees, 30.7% of intermediate occupations, 10.4% of managers and, 4.7% of manual workers. Twenty-two percent of workers were classed as deprived. Also, 43.2% of workers were exposed to three or more occupational hazards during pregnancy. Only 17.7% of workers had medical visits with OHP during pregnancy and 14.7% benefited from workstation adjustments. In contrast, the level of sick leaves was high (74.2%). Our results argue for the need to follow pregnancies at work. However, the low level of prevention activities and the high level of sick leaves raise the question of the management of pregnant women at work. Copyright © 2017 Elsevier Masson SAS.

    Urszula Wilczyńska

    2013-06-01

    Full Text Available Background: The aim of the paper was to present basic statistical data on occupational diseases diagnosed in 2012. Material and Methods: The work was based on the data from "Occupational Disease Reporting Forms" received by the Central Register of Occupational Diseases in 2012. The data comprised information on nosologic units, gender and age of patients, duration of occupational exposure, sections of the national economy and voivodeships. The incidence was specified in terms of the number of cases in relation to paid employees or to employed people. Results: The number of occupational diseases accounted for 2402 cases. The incidence rate was 23 cases per 100 000 paid employees. In spite of the general decline in the number of cases, the incidence of infectious and parasitic diseases increased by 8.6%. The highest incidence was noted for infectious and parasitic diseases (6.8/100 000, pneumoconioses (5.5/100 000, hearing loss (2.1/100 000, diseases of: the peripheral nervous system (2/100 000, voice disorders (1.9/100 000 and the musculo-skeletal system pathologies (1.1/100 000. The pathologies specified above accounted in total for 84% of all occupational diseases. The industrial sectors of the national economy characterized by the highest incidence included mining and quarrying (288.3/100 000 and manufacturing (27.8/100 000. The highest incidence was recorded in the Silesian (46.2/100 000 and the lowest in the Opolskie (4.2/100 000 voivodeships. Conclusions: The downward trend in the incidence of occupational diseases continues. Different incidence of voice disorders among teachers in individual provinces suggests that uniform preventive, diagnostic and certification standards are missing. Med Pr 2013;64(3:317–326

Mean values of the level of occupational burnout for the study group amounted to 39.3 ± 30.9 with regard to emotional exhaustion, 30.64 ± 27.89 with respect to the depersonalization subscale and 66.26 ± 27.94 – the lowered level of job satisfaction. Conclusions . 1. The studied nursing personnel showed symptoms of occupational burnout in all dimensions of the syndrome, i.e. high levels of emotional exhaustion and depersonalization as well as low job satisfaction. 2. Individuals with higher education scored lower on the emotional exhaustion scale. 3. Emotional exhaustion is influenced by workplace and position.

  19. Occupational balance: exploring the relationships among daily occupations and their influence on well-being.

    Backman, Catherine L

    2004-10-01

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

    ExternE National Implementation is a continuation of the ExternE Project, funded in part by the European Commission's Joule III Programme. This study is the result of the ExternE National Implementation Project for Finland. Three fuel cycles were selected for the Finnish study: coal, peat and wood-derived biomass, which together are responsible for about 40% of total electricity generation in Finland and about 75% of the non-nuclear fuel based generation. The estimated external costs or damages were dominated by the global warming (GW) impacts in the coal and peat fuel cycles, but knowledge of the true GW impacts is still uncertain. From among other impacts that were valued in monetary terms the human health damages due to airborne emissions dominated in all the three fuel cycles. Monetary valuation for ecosystem impacts is not possible using the ExternE methodology at present. The Meri-Pori power station representing the coal fuel cycle is one of the world's cleanest and most efficient coal-fired power plants with a condensing turbine. The coal is imported mainly from Poland. The estimated health damages were about 4 mECU/kWh, crop damages an order of magnitude lower and damages caused to building materials two orders of magnitude lower. The power stations of the peat and biomass fuel cycles are of CHP type, generating electricity and heat for the district heating systems of two cities. Their fuels are of domestic origin. The estimated health damages allocated to electricity generation were about 5 and 6 mECU/kWh, respectively. The estimates were case-specific and thus an generalisation of the results to the whole electricity generation in Finland is unrealistic. Despite the uncertainties and limitations of the methodology, it is a promising tool in the comparison of similar kinds of fuel cycles, new power plants and pollution abatement technologies and different plant locations with each other.

    The United States Nuclear Regulatory Commission contracted with Pacific Northwest Laboratory (PNL) to provide technical assistance in establishing operational guidelines, with respect to radiation control programs and methods of minimizing occupational radiation exposure, at Low-Level Waste (LLW) disposal sites. The PNL, through site visits, evaluated operations at LLW disposal sites to determine the adequacy of current practices in maintaining occupational exposures as low as is reasonably achievable (ALARA). The data sought included the specifics of: ALARA programs, training programs, external exposure control, internal exposure control, respiratory protection, surveillance, radioactive waste management, facilities and equipment, and external dose analysis. The results of the study indicated the following: The Radiation Protection and ALARA programs at the three commercial LLW disposal sites were observed to be adequate in scope and content compared to similar programs at other types of nuclear facilities. However, it should be noted that there were many areas that could be improved upon to help ensure the health and safety of occupationally exposed individuals.

    The U.S. Department of Energy (DOE) Office of Analysis within the Office of Health, Safety and Security (HSS) publishes the annual DOE Occupational Radiation Exposure Report to provide an overview of the status of radiation protection practices at DOE (including the National Nuclear Security Administration [NNSA]). The DOE 2012 Occupational Radiation Exposure Report provides an evaluation of DOE-wide performance regarding compliance with Title 10, Code of Federal Regulations (C.F.R.), Part 835, Occupational Radiation Protection dose limits and as low as reasonably achievable (ALARA) process requirements. In addition, the report provides data to DOE organizations responsible for developing policies for protection of individuals from the adverse health effects of radiation. The report provides a summary and an analysis of occupational radiation exposure information from the monitoring of individuals involved in DOE activities. Over the past 5-year period, the occupational radiation exposure information is analyzed in terms of aggregate data, dose to individuals, and dose by site. As an indicator of the overall amount of radiation dose received during the conduct of operations at DOE, the report includes information on collective total effective dose (TED). The TED is comprised of the effective dose (ED) from external sources, which includes neutron and photon radiation, and the internal committed effective dose (CED), which results from the intake of radioactive material into the body. The collective ED from photon exposure decreased by 23% between 2011 and 2012, while the neutron dose increased by 5%. The internal dose components of the collective TED decreased by 7%. Over the past 5-year period, 99.99% of the individuals receiving measurable TED have received doses below the 2 roentgen equivalent in man (rems) (20 millisievert [mSv]) TED administrative control level (ACL), which is well below the DOE regulatory limit of 5 rems (50 mSv) TED annually.

    The IAEA recommendation contains the guidance on: (1) establishing monitoring programmes; (2) the interpretation of results; (3) records keeping; (4) quality assurance. The objectives for workplace monitoring including the recommended methods are also involved. The choice of personal dosemeter depends not only on the type of radiation but also on the method of interpretation what will be used: (1) photon dosemeters giving information only on the personal dose equivalent Hp(10) - mostly TL or RPL dosemeters are used; (2) photon dosemeter of discriminating type giving, in addition to Hp(10) and Hp(0.07), some indication of radiation type and effective energy and detection of electrons - data which must be known for E calculation -mostly film badge is used; (3) extremity dosemeters giving information on Hp(0.07) - mostly TL dosemeters are used; (4) neutron dosemeters giving information on Hp(10) -track-etch or albedo dosemeters are used. The monitoring service should have quality assurance testing which is an organization's internal system of procedures and practices which assures the quality of its service. This process may be part of the approval performance testing which is a part of approved procedures carried out be the authoritative organization in regular intervals. The approved monitoring service should perform the dose records keeping which serve the protection of the workers and these data are the part of the Register of the Professional Exposures which is mostly organized by the authoritative body.

    2010-12-01

    Occupational therapy interventions in the community, a fast expanding practice setting, are central to an important social priority, the ability to live at home. These interventions generally involve only a small number of home visits, which aim at maximising the safety and autonomy of community-dwelling clients. Knowing how community occupational therapists determine their interventions, i.e. their clinical reasoning, can improve intervention efficacy. However, occupational therapists are often uninformed about and neglect the importance of clinical reasoning, which could underoptimise their interventions.   To synthesise current knowledge about community occupational therapists' clinical reasoning.   A scoping study of the literature on community occupational therapists' clinical reasoning was undertaken.   Fifteen textbooks and 25 articles, including six focussing on community occupational therapists' clinical reasoning, were reviewed. Community occupational therapists' clinical reasoning is influenced by internal and external factors. Internal factors include past experiences, expertise and perceived complexity of a problem. One of the external factors, practice context (e.g. organisational or cultural imperatives, physical location of intervention), particularly shapes community occupational therapists' clinical reasoning, which is interactive, complex and multidimensional. However, the exact influence of many factors (personal context, organisational and legal aspects of health care, lack of resources and increased number of referrals) remains unclear.   Further studies are needed to understand better the influence of internal and external factors. The extent to which these factors mould the way community occupational therapists think and act could have a direct influence on the services they provide to their clients. © 2010 The Authors.

  8. Shaping knowledge regarding occupation: examining the cultural underpinnings of the evolving concept of occupational identity.

    Rudman, Deborah Laliberte; Dennhardt, Silke

    2008-09-01

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

    This report is the proceedings of the National Conference on Environmental Externalities. A environmental externality is the environmental impact of a process or a plant that society must endure. It is a social cost and is paid, but not by the company who produced it or the company's customers who endure it. The main purpose of this report is to gather the many designs and ideas of how and why to internalize the externalities into the pricing systems of the public utility commissions, especially that of the electric utilities. Economic and sociological aspects of the internalization of these externalities are given in these proceedings. Individual papers are processed separately for databases. (MB)

    Identify the cardiovascular risk factors in a group of workers in the province of Salamanca, protected by external prevention services, as regards exposure to occupational carcinogens, by sector of activity and gender. An observational descriptive epidemiological study was conducted. The sample selection was by stratified random sampling in each entity. The variables collected by questionnaire were, sociodemographic characteristics, exposure to occupational carcinogens, and cardiovascular risk factors (smoking, hypertension, dyslipidemia, and diabetes), using the clinical-work histories as a source of information. Statistically significant differences were observed in cardiovascular risk according to the exposure to occupational carcinogens (p <0.001), primarily among workers in the industry sector. A total of 32% of the workers in the province of Salamanca was exposed to some occupational carcinogen. Women were more exposed in the service sector and men in the agriculture and livestock sector. Nearly one third of the workers belonging to the external prevention services of the province of Salamanca, were exposed to some kind of occupational carcinogens. The most frequent being biological risks, solvent products, and silica, which were above the national mean of exposure. It is important to consider the exposure to occupational carcinogens in the implementation of interventions in the prevention of cardiovascular risk in the work place.

    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.

    Few studies have examined the role of occupational therapy working in a primary care setting. The objective of the study was to describe the emerging role of occupational therapy in Family Health Teams, a model of interprofessional primary care. A multiple case study design was used to provide in-depth description of the occupational therapy role. Data collection included interviews, document analyses, and questionnaires. Each case was first analyzed individually, followed by cross-case analyses to determine common themes. The role of occupational therapy in Family Health Teams epitomizes that of a generalist, whose overarching focus is on function. Occupational therapists are working across the life span with a wide range of client populations. Older adults and individuals with complex chronic conditions are two prominent areas of occupational therapy focus. Understanding the impact of health conditions on daily function and enabling participation in activities are unique and important contributions of occupational therapy.

  19. Civilian law: from occupational medicine to occupational event.

    Science.gov (United States)

    Mpotos, N; Watelet, J B

    Civilian law:from occupational medicine to occupational event. Despite the growing importance of objective measurements, the health effects of many occupational risk factors are currently not fully quantified. Occupational noise, as a widespread risk factor, is illustrative in this regard; there is a strong body of evidence linking it to an important health outcome (hearing loss), but it is less decisively associated with others (such as psychological disorders). It is also distinct from environmental noise, and therefore falls under the responsibility of employers as well as individuals. Noise-induced hearing loss (NIHL) is, at present, incurable and irreversible. However, it is preventable, if effective and global hearing conservation programmes can be implemented. These programmes should not be isolated efforts, but should be integrated into the overall hazard prevention and control programme of the workplace. Belgian law encompasses a set of provisions for prevention and the protection of the health and safety of workers within the workplace, including aspects pertaining to the hygiene of the workplace and psychosocial aspects at work (stress, violence, bullying and sexual harassment, among others). In principle, combating environmental noise is fully addressed in this country. However, other levels of policy-making also play an important role in this regard. For example, the federal government is in charge of product standards, and therefore also of noise emission standards for products. The interpretation and enforcement of Belgian legislation on well-being at work converts European directives and international agreements on well-being at work into Belgian law.

    This report is the third in a series of annual reports on Occupational Radiation Exposures in Canada. The data is derived from the Radiation Protection Bureau's National Dose Registry which includes dose records for radiation workers. The report presents average yearly doses by region and occupational category, dose distributions, and variation of average doses with time. Statistical data concerning investigations of high exposures reported by the National Dosimetry Services are included and individual cases are briefly summarized where the maximum permissible dose is exceeded. The decrease in the overall average doses established over the last 20 years appears to be changing. In some occupational categories a consistent upward trend is observed

    Occupational rhinitis is characterized by nasal congestion, rhinorrhea, nasal itching, and/or sneezing that occur secondary to exposures in the workplace. This disease can be classified into allergic or nonallergic subgroups based upon the underlying disease pathogenesis as well as the type of causative agent. While the true prevalence of occupational rhinitis is unknown, there are certain professions and occupational exposures that place workers at a higher risk for developing the disease. Additionally, occupational rhinitis can be associated with occupational asthma and upper airway symptoms may precede those of the lower respiratory tract. Taken together, occupational rhinitis is an important disease for study given its medical as well as socioeconomic implications. This review will focus on the classification of occupational rhinitis as well the prevalence, diagnosis, and treatment strategies.

    Occupational stress literature emphasizes the importance of assessment and management of work related stress. The recognition of the harmful physical and psychological effects of stress on both individuals and organizations is widely studied in many parts of the world. However, in other regions such research is only at the introductory stages. The present study examines occupational stress of employees in the banking sector. A sample of 60 bank employees at different organizational levels and educational backgrounds was used. Data collection utilized the Occupational Stress Indicator (OSI). Results of data analysis provided evidence that employees' educational levels affect the degree of stress they experience in various ways. Bank employees cannot afford the time to relax and "wind down" when they are faced with work variety, discrimination, favoritism, delegation and conflicting tasks. The study also shows the degree to which some employees tend to bring work-related problems home (and take family problems to work) depends on their educational background, the strength of the employees' family support, and the amount of time available for them to relax. Finally, the drinking habits (alcohol) of the employees were found to play a significant role in determining the levels of occupational stress.

    Kilbom, A

    1988-01-01

    In two longitudinal studies, initial muscle strength and endurance of the shoulder-forearm muscles were related to deterioration of shoulder-neck-arm disorders after one year. Group I (n = 32) worked in the automobile industry assembling car motors. Their work was performed when standing and walking, and implied varied postures and exertion of external forces. Group II (n = 96) worked in the electronics industry assembling printed circuit boards. They worked sitting down and were exposed mainly to postural static loads. Muscle strength was negatively related to deterioration in group I but no such relationship was found in group II. The mechanism of occupational muscular injury is discussed, and it is suggested that mechanical overstress of the musculoskeletal system causes injury in occupations where external forces are exerted. The mechanism of injury in static, postural loads remains to be explained.

    There is a growing requirement for policy analysts to take account of the environment in their decision making and to undertake the specified cost-benefit analysis. Within the European Union this is reflected in the 5th Environmental Action Programme, and the Commission's White Paper entitled 'Growth, competitiveness, employment and the ways forward to the 21st century'. This has led to a need for evaluation of environmental externalities. The ExternE Project commenced in 1991 as the European part of a collaborative study between the European Commission and the US Department of Energy. It aims to be the first systematic approach to the evaluation of external costs of a wide range of different fuel cycles. The project will result in an operational accounting framework for the quantification and monetarisation of priority environmental and other externalities. This framework will allow the calculation of the marginal external costs and benefits for specific power plants, at specific sites using specified technologies. There are three major phases in the project. Phase 1 was undertaken in collaboration with the US Department of Energy. In this phase the teams jointly developed the conceptual approach and methodology and shared scientific information for application to a number of fuel cycles. On the European side work concentrated on the nuclear and coal fuel cycles which together were expected to raise many of the fundamental issues in fuel cycle analysis. The project is currently nearing completion of Phase 2. During this phase the methodology has been applied to a wide range of different fossil, nuclear and renewable fuel cycles for power generation and energy conservation options. Also a series of National Implementation Programmes is underway in which the methodology and accounting framework are being applied to reference sites throughout Europe. In addition the general methodology is being extended to address the evaluation of externalities associated with

    The nature of occupational engagement for homeless people living with mental illnesses is not well understood, and there are few studies to date that examine the occupational lives of these individuals. This research study seeks to understand how this group of individuals engages in occupations. The central question is "What is the nature of occupational engagement by homeless adults living with mental illnesses in Toronto?" A constant comparative method of analysis was used in a secondary analysis of 60 interviews with homeless adults experiencing mental illness. Four themes emerged that describe the nature of occupational engagement for this group: occupations as enjoyment, occupations as survival/risk, occupations as passing time, and occupations as self-management. Implications. This research informs occupational therapy interventions aimed at optimizing engagement, health, and well-being for homeless adults living with mental illnesses.

  8. Independence: proposing an initial framework for occupational therapy.

    The concept of independence is common in occupational therapy theory and practice but has rarely been clearly defined or conceptualized within in occupational therapy literature and there seems to be no standard definition. This can result in ambiguity, which potentially jeopardizes client-centred practice. This paper proposes an occupational therapy independence framework (OTIF) that synthesizes the range of characterizations of independence in a practically useful and occupation-centred manner. A review of literature, clinical experience, doctoral research and conversations with occupational therapists and disabled people, in particular those involved in a disability activism group and people with physical disabilities, has led to the development of the OTIF. Independence and interdependence, as characterized in the OTIF, occur when an individual exerts choice over occupational performance and can engage in occupations in a manner acceptable to the individual. Interdependence results when occupations are performed with another person whereas independence involves solitary occupational performance. Dependence typically results from inability to choose occupations or a mismatch between performance capacity and environmental factors. The OTIF has the potential to clarify the conceptualization of independence within occupational therapy theory and practice. This initial proposal is presented to stimulate debate and discussion.

  9. Inference for occupancy and occupancy dynamics

    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.

    The German uranium miners cohort study comprises 58,982 men employed in the GDR by the Wismut company for at least six months between 1946 and 1989. Particularly in the early years, miners were exposed to high levels of radon, silica and other harmful substances. The aim of the cohort study is to investigate the health effects of occupational exposures. The cohort was established in 1998 with mortality follow-ups every five years, i.e. vital status and cause of death are ascertained. Annual exposures to radon progeny, external gamma-radiation, long-lived radionuclides, fine dust, silica and arsenic dust were individually assessed by means of a comprehensive job-exposure matrix. For data analyses Poisson regression models were used. By end of 2008, 25,438 (43 %) cohort members were deceased with known cause of death in 94 %. In total 7,780 cancer mortalities were observed, including 3,500 from lung cancer. Lung cancer mortality is twice as high as in the general population largely due to occupational radon progeny and silica exposure. Also 975 silicosis deaths were observed and there is some evidence for a relationship between radon progeny exposure and cancers of the extra-thoracic airways. Circulatory diseases and non-malignant diseases of the airways were also investigated, but no relationship to occupational exposure was found. Up to now health effects of uranium mining in the Wismut cohort primarily manifest themselves as increases in lung cancer and silicosis mortality due to high radon progeny and silica exposure. With increasing duration of follow-up, further findings regarding more rare causes of death and levels of exposure relevant today are expected.

    Performance is perhaps the most central concept in public administration research, and this article discusses theoretically and investigates empirically how we can obtain more consistent performance measures. Theoretically, we combine existing arguments in public administration with institutional...... theory and the sociology of professions. Empirically, we ask whether different measures of individual performance produce different results. The investigated performance measures vary with regard to risk of common data source bias, standardization of assessment criteria, and external verification...... of the assessment. Our investigated explanatory variables are intrinsic motivation, public service motivation, and job satisfaction. Combining survey and administrative data for 747 lower secondary school teachers (teaching 5,679 students in 85 schools), we analyze 4 different measures of the same performance...

    The U.S. Department of Energy (DOE) Office of Corporate Safety Analysis (HS-30) within the Office of Health, Safety and Security (HSS) publishes the annual DOE Occupational Radiation Exposure Report to provide an overview of the status of radiation protection practices at DOE.* The annual DOEOccupational Radiation Exposure 2007 Report provides an evaluation of DOE-wide performance regarding compliance with DOE Part 835 dose limits and ALARA process requirements. In addition the report provides data to DOE organizations responsible for developing policies for protection of individuals from the effects of radiation. This report provides a summary and an analysis of occupational radiation exposure information from the monitoring of individuals involved in DOE activities. The occupational radiation exposure information is analyzed in terms of aggregate data, dose to individuals, and dose by site over the past five years.

  14. Coherent polarization driven by external electromagnetic fields

    2010-01-01

    The coherent interaction of the electromagnetic radiation with an ensemble of polarizable, identical particles with two energy levels is investigated in the presence of external electromagnetic fields. The coupled non-linear equations of motion are solved in the stationary regime and in the limit of small coupling constants. It is shown that an external electromagnetic field may induce a macroscopic occupation of both the energy levels of the particles and the corresponding photon states, governed by a long-range order of the quantum phases of the internal motion (polarization) of the particles. A lasing effect is thereby obtained, controlled by the external field. Its main characteristics are estimated for typical atomic matter and atomic nuclei. For atomic matter the effect may be considerable (for usual external fields), while for atomic nuclei the effect is extremely small (practically insignificant), due to the great disparity in the coupling constants. In the absence of the external field, the solution, which is non-analytic in the coupling constant, corresponds to a second-order phase transition (super-radiance), which was previously investigated.

  15. Occupational risk factors and voice disorders.

    Vilkman, E

    1996-01-01

    From the point of view of occupational health, the field of voice disorders is very poorly developed as compared, for instance, to the prevention and diagnostics of occupational hearing disorders. In fact, voice disorders have not even been recognized in the field of occupational medicine. Hence, it is obviously very rare in most countries that the voice disorder of a professional voice user, e.g. a teacher, a singer or an actor, is accepted as an occupational disease by insurance companies. However, occupational voice problems do not lack significance from the point of view of the patient. We also know from questionnaires and clinical studies that voice complaints are very common. Another example of job-related health problems, which has proved more successful in terms of its occupational health status, is the repetition strain injury of the elbow, i.e. the "tennis elbow". Its textbook definition could be used as such to describe an occupational voice disorder ("dysphonia professional is"). In the present paper the effects of such risk factors as vocal loading itself, background noise and room acoustics and low relative humidity of the air are discussed. Due to individual factors underlying the development of professional voice disorders, recommendations rather than regulations are called for. There are many simple and even relatively low-cost methods available for the prevention of vocal problems as well as for supporting rehabilitation.

    Open access is a well-known externality problem in fisheries causing excess capacity and overfishing. Due to global warming, externality problems from CO2 emissions have gained increased interest. With two externality problems, a first-best optimum can be achieved by using two regulatory...... instruments. However, solving the open-access externality problem also affects CO2 emissions. By using a bio-economic model covering Iceland, Norway, Denmark, Sweden, and the Faroe Islands, it is shown that regulations of the open-access externality problem have a large effect on both economic performance...... and CO2 emissions, while an additional CO2 regulation only has minor effects. The second-best solution achieved by only regulating open access reduces emissions by approximately 50% compared to current fisheries, with the exception of Iceland, which already has a well-developed fisheries management...

    This study examined psychological empowerment and organizational identification as outcomes of occupational context and predictors of occupational safety performance. In this study, 171 hospital employees from 17 units and 21 occupations completed surveys measuring psychological empowerment, organizational identification, and supervisor safety practices. They also completed measures of 2 dimensions of safety performance: use of personal protective equipment and safety participation. These data were merged with Occupational Information Network (O*NET) context ratings of occupational hazards and physical demands. Results indicated that occupational hazards were negatively related to individual-level psychological empowerment and organizational identification, which were in turn positively related to safety participation. Psychological empowerment and organizational identification also interacted with perceptions of supervisor safety actions in the prediction of personal protective equipment use. Results have implications for organizational safety performance and point to the role of occupational context in psychological empowerment and the extent to which employees participate in the safety of their worksite.

    Principal results of individual dosimetric control (IDC) are presented for persons occupationally exposed to external irradiation in industry, medicine, science and education. The size of the population monitored increased from 515 subjects in 1964 to 7600 subjects in 1976 (meeting 100% of the needs for IDC). On the average, 90% of persons received doses -4 a -1 - for medicine; and 7.7 x 10 -4 a -1 - for industry. The stochastic somatic risk of radiation is likewise low: -4 a -1 . Predicted values of lifetime doses do not exceed 2 AEDs for about 90% of the observed population. For gamma radiography and curietherapy, these values are within 5-6 AEDs. (author)

    The occupational stress is associated with dissatisfaction, excessive demand at work and personal factors. Those factors can reduce work performance and can predispose workers to various diseases. Workers' health may be protected if there is encouragement to face challenges, which may lessen the impact on psychological and somatic stress and thus have greater personal and professional satisfaction. The aim of this study was to evaluate the association between occupational stress and work engagement. Participated in this study 457 male and female workers of a metallurgical industry. Subjects answered personal data, and the Job Stress Scale and Utrecht Work Engagement Scale were applied. Results showed an association between occupational stress and work engagement (P=0,001). The way the individual deals with his frustrations, or rather the work engagement, is associated with the occupational stress.

    We develop a social network model of occupational segregation between different social groups, generated by the existence of positive inbreeding bias among individuals from the same group. If network referrals are important for job search, then expected homophily in the contact network structure...... induces different career choices for individuals from different social groups. This further translates into stable occupational segregation equilibria in the labor market. We derive the conditions for wage and unemployment inequality in the segregation equilibria and characterize first and second best...... social welfare optima.

    This study aimed to assess effects of chronic occupational exposure on immune status in Mayak workers chronically exposed to ionizing radiation (IR). The study cohort consists of 77 workers occupationally exposed to external gamma-rays at total dose from 0.5 to 3.0 Gy (14 individuals) and workers with combined exposure (external gamma-rays at total dose range 0.7-5.1 Gy and internal alpha-radiation from incorporated plutonium with a body burden of 0.3-16.4 kBq). The control group consists of 43 age- and sex-matched individuals who never were exposed to IR, never involved in any cleanup operations following radiation accidents and never resided at contaminated areas. Enzyme-linked immunoassay and flow cytometry were used to determine the relative concentration of lymphocytes and proteins. The concentrations of T-lymphocytes, interleukin-8 and immunoglobulins G were decreased in external gamma-exposed workers relative to control. Relative concentrations of NKT-lymphocytes, concentrations of transforming growth factor-β, interferon gamma, immunoglobulins A, immunoglobulins M and matrix proteinase-9 were higher in this group as compared with control. Relative concentrations of T-lymphocytes and concentration of interleukin-8 were decreased, while both the relative and absolute concentration of natural killers, concentration of immunoglobulins A and M and matrix proteinase-9 were increased in workers with combined exposure as compared to control. An inverse linear relation was revealed between absolute concentration of T-lymphocytes, relative and absolute concentration of T-helpers cells, concentration of interferon gamma and total absorbed dose from external gamma-rays in exposed workers. For workers with incorporated plutonium, there was an inverse linear relation of absolute concentration of T-helpers as well as direct linear relation of relative concentration of NKT-lymphocytes to total absorbed red bone marrow dose from internal alpha-radiation.

    Though scientifically undisputed, cutaneous syncarcinogenesis is not reflected in German occupational disease (OD) regulations, which tend to be guided by the tenet of monocausality. Recognition of nonmelanoma skin cancer (NMSC) and its precursor lesions as OD requires individual assessment as to whether the requirements pursuant to either OD 5103 (occupational exposure to natural UV radiation) or OD 5102 (occupational exposure to polycyclic aromatic hydrocarbons) are fulfilled. Retrospective analysis of 28 patients (median age 72.5 years) with NMSC and respective precursor lesions who had been occupationally exposed to natural UV radiation and polycyclic aromatic hydrocarbons. All cases had undergone expert medical assessment between September 2012 and September 2015. According to our assessments, all 28 cases met the occupational requirements pursuant to OD 5103 and 5102. In 26 cases (93 %), we recommended recognition of skin cancer as occupational disease pursuant to both OD 5103 and OD 5102. The competent occupational insurance association (BG) followed our recommendation in four cases. In eight cases, recognition was solely based on OD 5103; in ten cases, only on OD 5102. Four cases were denied recognition. Following adequate cumulative occupational exposure to natural UV light as well as occupational exposure to polycyclic aromatic hydrocarbons, NMSC or its precursor lesions arising in UV-exposed areas should be reported to the competent occupational insurance association as "OD 5103 and 5102 in terms of syncarcinogenesis". Apart from the fact that the ensuing recognition proceedings will be able to more adequately reflect real-life workplace conditions, filing a report pursuant to both ODs also allows for recognition of basal cell carcinoma as occupational disease. According to current regulations, this would not be possible, if the assessment were solely based on OD 5103. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons

    Several important issues which affect external exposure in contaminated Chernobyl areas have been investigated using field measurements and computational simulations since 1992. The objectives of the study were: 1) the development of a mobile survey method to collect radiation data over the contaminated wide areas in a shot time; 2) the verification of a method to infer external dose to the population; 3) the provision of basic data used for evaluation of external dose due to gamma ray using a Monte Carlo simulation method. To develop a method to rapidly measure radiation over wide areas and map the extend of fallout, a mobile survey system was constructed and tested; the conversion factors to convert the measured data to required quantities were examined; and finally a detailed contamination map was created. The field surveys were implemented by using a land rover and a helicopter. To infer external dose to inhabitants, radiation measurements were carried out in the living environments using accurate dose meters in addition to individual dose measurements using glass dosimeters. Individual doses were inferred from occupancy factors and dose rate data measured with portable dose rate meters in and around houses. The evaluated doses were compared to directly measured individual doses with glass dosimeters in the seven settlements. A good agreement was observed with an error margin of approximate 20%. Basic data used for the evaluation of environmental gamma-ray dose rate were calculated using a Monte Carlo method. The following two kinds of data have been provided from the calculation: a) conversion factors from the nuclide concentration in the ground to the air kerma rate at 1 m height; and b) shielding factors of a typical Chernobyl house for gamma radiation.

From January 2012 to March 2016 external cephalic versions carried out at our center, which were a total of 52. We collected data about female age, gestational age at the time of the external cephalic version, maternal body mass index (BMI), fetal variety and situation, fetal weight, parity, location of the placenta, amniotic fluid index (ILA), tocolysis, analgesia, and newborn weight at birth, minor adverse effects (dizziness, hypotension and maternal pain) and major adverse effects (tachycardia, bradycardia, decelerations and emergency cesarean section). 45% of the versions were unsuccessful and 55% were successful. The percentage of successful vaginal delivery in versions was 84% (4% were instrumental) and 15% of caesarean sections. With respect to the variables studied, only significant differences in birth weight were found; suggesting that birth weight it is related to the outcome of external cephalic version. Probably we did not find significant differences due to the number of patients studied. For women with breech presentation, we recommend external cephalic version before the expectant management or performing a cesarean section. The external cephalic version increases the proportion of fetuses in cephalic presentation and also decreases the rate of caesarean sections.

    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.

Ionizing radiation is a confirmed human carcinogen for most organ sites. This study, therefore, was aimed to estimate lifetime cancer risk from occupational exposure among radiologic technologists that has been recruited in 2012-2013. Our findings showed a small increased cancer risk in radiologic technologists from their occupational radiation exposure in Korea. However, continuous dose monitoring and strict regulation on occupational safety at the government level should be emphasized to prevent any additional health hazards from occupational radiation exposure.

    2006-02-01

    Full Text Available Abstract This editorial is to announce the Journal of Occupational Medicine and Toxicology, a new Open Access, peer-reviewed, online journal published by BioMed Central. Occupational medicine and toxicology belong to the most wide ranging disciplines of all medical specialties. The field is devoted to the diagnosis, prevention, management and scientific analysis of diseases from the fields of occupational and environmental medicine and toxicology. It also covers the promotion of occupational and environmental health. The complexity of modern industrial processes has dramatically changed over the past years and today's areas include effects of atmospheric pollution, carcinogenesis, biological monitoring, ergonomics, epidemiology, product safety and health promotion. We hope that the launch of the Journal of Occupational Medicine and Toxicology will aid in the advance of these important areas of research bringing together multi-disciplinary research findings.

  17. Quality of life, participation and occupational rights: A capabilities perspective.

    Science.gov (United States)

    Hammell, Karen Whalley

    2015-04-01

    Research suggests that perceptions of diminished quality of life among people with a severe physical impairment might be a consequence of environmental barriers and inequity of opportunity rather than the impairment itself. However, occupational therapists remain preoccupied with assessing and addressing individual dysfunctions and have directed little attention to assessing and challenging inequitable environmental constraints on people's occupational opportunities. To highlight briefly what is known about environmental impacts on quality of life among people with impairments; to outline the relationship between occupational rights and human rights; to explore the concept of 'participation' and thereafter to outline the relevance of the Capabilities Approach for occupational therapists who seek to address inequalities of occupational opportunity and inequities in participation. Sen's Capabilities Approach focuses on equality of the opportunity to 'do', and is relevant to occupational therapy in the context of the World Health Organisation's construct of 'participation', the United Nations' Convention on the Rights of Persons with Disabilities, and the World Federation of Occupational Therapists' (WFOT) Position Statement on Human Rights. Adoption of Sen's Capabilities Approach might facilitate critical occupational therapy practices focussed on equality of occupational opportunities and on the fulfilment of occupational rights, in accordance with the standards of rights-based practices advocated by disability scholars, WFOT and the UN. © 2015 Occupational Therapy Australia.

  18. The pan occupational paradigm: development and key concepts.

    Science.gov (United States)

    Hitch, Danielle; Pepin, Genevieve; Stagnitti, Karen

    2018-01-01

    Wilcock's Occupational Perspective of Health (OPH) aligns with the profession's re-discovery of its holistic, occupationally focused roots. Its dimensions of occupation-doing, being, becoming and belonging - resonate strongly with therapists on an intuitive, implicit level. However, its documented use in practice to date has been sparse, and several barriers to its implementation have been identified. The aim of this article is to present a renewal of the OPH - the Pan Occupational Paradigm (POP). Method of development: POP was developed using critical analysis, reflection and a comprehensive literature review. Each stage of development is described in detail, including the POP's inherent assumptions. Key concepts: POP retains the four dimensions of occupation, and shows their interdependent role within occupational entities (e.g. individuals, groups or communities). An entity can be approached by occupational therapy at any point and all the dimensions (either directly or indirectly) can be engaged. Occupational entities move along a continuum of wellbeing, and this movement can be in both positive and negative directions over a lifespan. POP is a distillation of occupational therapy's unique way of knowing about occupation and the promotion of wellbeing. It is put forward as an updated paradigm for occupational therapy in the 21st century.

    2002-01-01

    External costs of energy have been assessed in a number of authoritative and reliable studies based upon widely accepted methodologies such as life cycle analysis (LCA). However, although those costs are recognised by most stakeholders and decision makers, results from analytical work on externalities and LCA studies are seldom used in policy making. The International Energy Agency (IEA) and the Nuclear Energy Agency (NEA) convened a joint workshop in November 2001 to offer experts and policy makers an opportunity to present state-of-the-art results from analytical work on externalities and debate issues related to the relevance of external costs and LCA for policy-making purposes. The findings from the workshop highlight the need for further work in the field and the potential rote of international organisations like the IEA and the NEA in this context. (authors)

    2017-04-01

    Full Text Available We present the idea of externally verifiable oblivious RAM (ORAM. Our goal is to allow a client and server carrying out an ORAM protocol to have disputes adjudicated by a third party, allowing for the enforcement of penalties against an unreliable or malicious server. We give a security definition that guarantees protection not only against a malicious server but also against a client making false accusations. We then give modifications of the Path ORAM [15] and Ring ORAM [9] protocols that meet this security definition. These protocols both have the same asymptotic runtimes as the semi-honest original versions and require the external verifier to be involved only when the client or server deviates from the protocol. Finally, we implement externally verified ORAM, along with an automated cryptocurrency contract to use as the external verifier.

  5. Hollywood takes on intellectual/ developmental disability: cinematic representations of occupational participation.

    Renwick, Rebecca; Schormans, Ann Fudge; Shore, Deborah

    2014-01-01

    Adults with intellectual/developmental disability (IDD), and their occupational participation, are vastly under-represented in Hollywood films. Because films often provide individuals' only experience of people with IDD, cinematic representations can influence audience perceptions. Thus, films can help inform public perceptions about desired and appropriate occupational participation for people with IDD, potentially impacting their access to meaningful occupational participation and achievement of occupational potential. Accordingly, this research examined occupational portrayals of adults with IDD in contemporary Hollywood films. Occupational portrayals, as defined here, refer to representations of the dynamic process of the person participating in occupation(s) in a context. Grounded theory methods guided coding and analysis of qualitative data collected from eight contemporary films using an occupation-focused tool. Two major, striking themes emerging from the qualitative analysis--infantilization and simplification of participation in complex occupations (with three associated sub-themes)--are discussed. Implications of the findings and future research directions are considered.

    2017-06-01

    Contemporary research is expanding understandings of occupation beyond that of the individual's doing, including the shared and social nature of occupation. The concept of collective occupation has been introduced to capture this broader understanding. This study aimed to explicate the concept of occupation in a Greek town. Ethnographic methodology was used and primary data were collected through observation, participation, and informal interviews. Analysis involved a hermeneutic process to develop a narrative of occupation in the town, including action, setting, and plots. Occupation, a dynamic and multidimensional process, served to maintain the self, family, and social fabric and balance between and within them. Collective occupation maintained the social fabric through three forms: informal daily encounters in public spaces, organization and associations, and celebration and commemoration. Occupational therapists may consider engaging with the potential power of such collective occupation when working toward social change to enable just and inclusive societies.

    The aim of the present study was to investigate the prevalence of burnout and occupational participation limitation among dental students in a dental school in Turkey. Four hundred fifty-eight dental students (females=153; males=305) were included in the study. The age range varied from 17-to-38 years. Maslach Burnout Inventory-Student Version (MBI-SV) and Canadian Occupational Performance Measure (COPM) were used to gather data. Descriptive analyses, t-test, and Kruskall-Wallis test for independent groups were used for data analyses. The results indicated that 26% of all the students have burnout in terms of emotional exhaustion (25%), cynicism (18%), and academic efficacy (14%). The results showed that burnout is statistically significant in relation to demographics (pstudents showed considerably decreased occupational performance and satisfaction scores, which suggested occupational participation limitations. Occupational performance and satisfaction scores were inversely correlated with emotional exhaustion and cynicism, while directly correlated with reduced academic efficacy (pburnout and occupational participation limitation can be seen among dental students. Students with burnout may also have occupational participation limitation. Enriching dental education programs with different psychological strategies may be useful for education of healthy dentists and improve the quality of oral and dental health services.

  12. Smart building temperature control using occupant feedback

    Science.gov (United States)

    Gupta, Santosh K.

    feedback signals, we propose a distributed solution, which ensures that a consensus is attained among all occupants upon convergence, irrespective of their temperature preferences being in coherence or conflicting. Occupants are only assumed to be rational, in that they choose their own temperature set-points so as to minimize their individual energy cost plus discomfort. We use Alternating Direction Method of Multipliers ( ADMM) to solve our consensus problem. We further establish the convergence of the proposed algorithm to the optimal thermal set point values that minimize the sum of the energy cost and the aggregate discomfort of all occupants in a multi-zone building. For simulating our consensus algorithm we use realistic building parameters based on the Watervliet test facility. The simulation study based on real world building parameters establish the validity of our theoretical model and provide insights on the dynamics of the system with a mobile user population. In the third part we present a game-theoretic (auction) mechanism, that requires occupants to "purchase" their individualized comfort levels beyond what is provided by default by the building operator. The comfort pricing policy, derived as an extension of Vickrey-Clarke-Groves (VCG) pricing, ensures incentive-compatibility of the mechanism, i.e., an occupant acting in self-interest cannot benefit from declaring their comfort function untruthfully, irrespective of the choices made by other occupants. The declared (or estimated) occupant comfort ranges (functions) are then utilized by the building operator---along with the energy cost information---to set the environment controls to optimally balance the aggregate discomfort of the occupants and the energy cost of the building operator. We use realistic building model and parameters based on our test facility to demonstrate the convergence of the actual temperatures in different zones to the desired temperatures, and provide insight to the pricing

    2018-01-01

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

  14. Radiation exams in occupational medical evaluations

    International Nuclear Information System (INIS)

    Gelsleichter, A.M.; Hunh, A.; Nandi, D.M.

    2017-01-01

    Introduction: In occupational medicine, medical care must be geared toward the prevention of worker health. However, occupational medical exams often seek only through rigorous screening, reduce absenteeism, and thus increase productivity. To meet this goal, many institutions include radiological examinations indiscriminately in their medical and expert evaluations, contrary to the principle of justification. Objective: To provide a reflection about the presence of radiological exams in occupational medical evaluations. Methodology: Literary review including legislation related to the research topic. Results: Portaria 453/98 ANVISA prohibits the performance of radiological examinations for employment or expert purposes, except in cases where the exam may bring a benefit to the health of the individual examined or to society. However, in some situations the Norma Regulamentadora number 7 of the Ministry of Labor and Employment provides for radiological exams as a parameter for monitoring occupational exposure. Article 168 of the Consolidation of Labor Laws also prescribes that additional examinations may be required, at the medical discretion, to determine the physical and mental fitness of the employee for the job. Conclusion: Although there are legal provisions that prohibit and others that allow radiological exams in medical occupational evaluations, companies and institutions should take into account that any radiological exam has a risk involved and should not request them in a compulsory and indiscriminate manner. Radiological exams are only permissible to elucidate the diagnostic hypothesis produced by clinical evaluation, in order to provide a real benefit for the individual

    Pan, Shijia; Bonde, Amelie; Jing, Jie; Zhang, Lin; Zhang, Pei; Noh, Hae Young

    2014-04-01

    In this paper, we present a room-level building occupancy estimation system (BOES) utilizing low-resolution vibration sensors that are sparsely distributed. Many ubiquitous computing and building maintenance systems require fine-grained occupancy knowledge to enable occupant centric services and optimize space and energy utilization. The sensing infrastructure support for current occupancy estimation systems often requires multiple intrusive sensors per room, resulting in systems that are both costly to deploy and difficult to maintain. To address these shortcomings, we developed BOES. BOES utilizes sparse vibration sensors to track occupancy levels and activities. Our system has three major components. 1) It extracts features that distinguish occupant activities from noise prone ambient vibrations and detects human footsteps. 2) Using a sequence of footsteps, the system localizes and tracks individuals by observing changes in the sequences. It uses this tracking information to identify when an occupant leaves or enters a room. 3) The entering and leaving room information are combined with detected individual location information to update the room-level occupancy state of the building. Through validation experiments in two different buildings, our system was able to achieve 99.55% accuracy for event detection, less than three feet average error for localization, and 85% accuracy in occupancy counting.

    This report is the proceedings of the National Conference on Environmental Externalities. A environmental externality is the environmental impact of a process or a plant that society must endure. It is a social cost and is paid, but not by the company who produced it or the company`s customers who endure it. The main purpose of this report is to gather the many designs and ideas of how and why to internalize the externalities into the pricing systems of the public utility commissions, especially that of the electric utilities. Economic and sociological aspects of the internalization of these externalities are given in these proceedings. Individual papers are processed separately for databases. (MB)

    In the modelling of external exposures due to cesium released during the reactor accident of Chernobyl, gamma dose rates in air over open undisturbed sites are considered to be different according to the unsoluble fraction in the deposit. This is taken into account by forming different classes according to the distance from the Chernobyl NPP. The effect of the different migration behavior in these distance classes on the gamma dose rate in air is found to increase with time. Predictions of gamma dose rates in air are based on measurements of the nuclear weapons tests fallout. Various population groups in the CIS countries are defined according to their place of residence (rural or urban), their occupation or age (indoor resp. outdoor workers, pensioners, school-children, or preschool-children), and their kind of residence (wooden, brick, or multi-storey house). Model results for various population groups are compared with the results of TLD-measurements of individual external exposures. For the calculation of inhalation doses, the new ICRP model for the respiratory tract was used. The dose assessments were conducted for measured size resolved activity distributions of resuspended material, obtained at different locations and for several kinds of agricultural operations. Inhalation doses vary considerably with respect to different kinds of work. Tractor drivers receive much higher doses than other agricultural workers, especially when the cabin window of the tractor is open. Effective doses due to the inhalation of resuspended plutonium are assessed to be a few μSv per initial deposit of one kBq/m 2 . Inhalation doses from 137 Cs are usually smaller by an order of magnitude than the doses from Pu, provided a high solubility is assumed for resuspended Cs

  1. Externality or sustainability economics?

    Bergh, Jeroen C.J.M. van den

    2010-01-01

    In an effort to develop 'sustainability economics' Baumgaertner and Quaas (2010) neglect the central concept of environmental economics-'environmental externality'. This note proposes a possible connection between the concepts of environmental externality and sustainability. In addition, attention is asked for other aspects of 'sustainability economics', namely the distinction weak/strong sustainability, spatial sustainability and sustainable trade, distinctive sustainability policy, and the ideas of early 'sustainability economists'. I argue that both sustainability and externalities reflect a systems perspective and propose that effective sustainability solutions require that more attention is given to system feedbacks, notably other-regarding preferences and social interactions, and energy and environmental rebound. The case of climate change and policy is used to illustrate particular statements. As a conclusion, a list of 20 insights and suggestions for research is offered. (author)

  2. [Prevention of Occupational Injuries Related to Hands: Calculation of Subsequent Injury Costs for the Austrian Social Occupational Insurance Institution (AUVA)].

    2015-08-01

    Occupational injuries cause short-term, direct costs as well as long-term follow-up costs over the lifetime of the casualties. Due to shrinking budgets accident insurance companies focus on cost reduction programmes and prevention measures. For this reason, a decision support system for consequential cost calculation of occupational injuries was developed for the main Austrian social occupational insurance institution (AUVA) during three projects. This so-called cost calculation tool combines the traditional instruments of accounting with quantitative methods such as micro-simulation. The cost data are derived from AUVA-internal as well as external economic data sources. Based on direct and indirect costs, the subsequent occupational accident costs from the time of an accident and, if applicable, beyond the death of the individual casualty are predicted for the AUVA, the companies in which the casualties are working, and the other economic sectors. By using this cost calculation tool, the AUVA classifies risk groups and derives related prevention campaigns. In the past, the AUVA concentrated on falling, accidents at construction sites and in agriculture/forestry, as well as commuting accidents. Currently, among others, a focus on hand injuries is given and first prevention programmes have been initiated. Hand injuries represent about 38% of all casualties with average costs of about 7,851 Euro/case. Main causes of these accidents are cutting injuries in production, agriculture, and forestry. Beside a low, but costly, number of amputations with average costs of more than 100,000 Euro/case, bone fractures and strains burden the AUVA-budget with about 17,500 and 10,500 € per case, respectively. Decision support systems such as this cost calculation tool represent necessary instruments to identify risk groups and their injured body parts, causes of accidents, and economic activities, which highly burden the budget of an injury company, and help derive

  3. Occupational therapists' perceptions of gender - a focus group study.

    2010-10-01

    Women and men are shaped over the courses of their lives by culture, society and human interaction according to the gender system. Cultural influences on individuals' social roles and environment are described in occupational therapy literature, but not specifically from a gender perspective. The purpose of this qualitative study was to explore how a sample of occupational therapists perceives the 'gender' concept. Four focus group interviews with 17 occupational therapists were conducted. The opening question was: 'How do you reflect on the encounter with a client depending on whether it is a man or a woman?' The transcribed interviews were analysed and two main themes emerged: 'the concept of gender is tacit in occupational therapy' and 'client encounters'. The occupational therapists expressed limited theoretical knowledge of 'gender'. Furthermore, the occupational therapists seemed to be 'doing gender' in their encounters with the clients. For example, in their assessment of the client, they focussed their questions on different spheres: with female clients, on the household and family; with male clients, on their paid work. This study demonstrated that occupational therapists were unaware of the possibility that they were 'doing gender' in their encounters with clients. There is a need to increase occupational therapists' awareness of their own behaviour of 'doing gender'. Furthermore, there is a need to investigate whether gendered perceptions will shorten or lengthen a rehabilitation period and affect the chosen interventions, and in the end, the outcome for the clients. © 2010 The Authors.

    Radiation exposures experienced by workers are widely explained. The first evidences of biological effects, the implications for human health and the radiological protection have been covered. The conceptual structure that covers the radiological protection and adequate protection without limiting benefits, the scientific basis of radiology, the benefits and risks of the radiological protection are specified. The effective per capita doses are exposed in medical uses both for Latin America and for other regions in the average radiology, dental radiology, nuclear medicine and radiotherapy. The manners of occupational exposures in the medicine are presented. Industrial uses have also its average effective dose in the industrial irradiation, industrial radiography and radioisotopes production. Within the natural radiation the natural sources can significantly contribute to occupational exposure and have their average effective dose. Occupational medical surveillance to be taken into industrial sites is detailed. In addition, the plan of international action for the solution of dilemmas of occupational exposures is mentioned and the different dilemmas of radioactive exposure are showed. The external irradiation, the acute diseases by radiations, the cutaneous syndrome of the chronic radiation, the radioactive contamination, the internal radioactive contamination, the combined lesion and accidental exposures are also treated [es

  9. Client perspectives on occupational therapy practice: are we truly client-centred?

    Science.gov (United States)

    Rebeiro, K L

    2000-02-01

    In Canada, the guidelines for the practice of occupational therapy are named and framed as client-centred. Two in-depth interviews were conducted with clients of mental health services about their experiences with a hospital-based occupational therapy service. These occupational therapy clients described their experiences as prescriptive, and as less than client-centred. With the publication of Enabling occupation: A Canadian occupational therapy perspective (Canadian Association of Occupational Therapists [CAOT], 1997) and an increasingly refined focus on being client-centred, these interviews highlight the challenges of a client-centred practice within the current health care environment. These occupational therapy clients raise issues of importance for occupational therapy. The participants stated that the prescription of 'activity', a lack of choice, and a focus upon the illness as opposed to the individual, served to diminish any collaborative partnership with the client and eliminate the client from any decision-making process. This distancing from the client, in their opinion, served to greatly diminish any therapeutic value of occupation. The participants recommended a greater focus upon occupational choice, consideration of the individual within the client, providing accepting, supportive environments, and using professional expertise on occupation to guide the client towards participation in meaningful occupation. These recommendations are strikingly similar to the most recent guidelines for the client-centred practice of occupational therapy in Canada. A discussion of the implications of these findings for the client-centred practice of occupational therapy is offered.

    1998-01-01

    In order to determine key competences required of occupational medicine specialists, common throughout Europe, a questionnaire has been developed and distributed among several European countries. The questionnaire contained 115 subjects related to 8 fields of activities carried out by occupational medicine physicians (occupational hazards to health, assessment of disability and fitness for work, communications, research methods, management, environmental medicine, occupational health law and ethics, and health promotion). In each of these fields, competences were classified into three following categories: knowledge, experience and skills. Respondents were asked to allocate a score from 0 to 5 for each subject, where 0 = not necessary; 1 = of minimum importance, and 5 = most important or essential. In Poland the questionnaire was distributed among two groups of specialists: group I--experienced specialists in occupational medicine (leading representatives of occupational health care management), and group II--relatively younger and less experienced occupational medicine physicians, participating in the specialist training, organised by The Nofer Institute of Occupational Medicine. A comprehensive analysis of the completed questionnaires was carried out in two dimensions: substantive (the importance of individual competences as perceived by Polish specialists in occupational medicine), and comparative (evaluation and interpretation of similarities and differences between two groups of respondents). A hierarchy of requirements, occupational medicine training in Poland is to satisfy, was reconstructed with two sets of competences, one recognised by respondents as needless and the other recognised as useful with different grades of importance. Some characteristic differences in opinions between two groups studies were highlighted.

    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.

    Tejado, J J; Guillén, J; Baeza, A

    2016-09-01

    Workers in the granite industry face an occupational hazard: silicosis due to the crystalline silica present in inhalable dust. As granite can also present a variable, and occasionally significant, content of naturally occurring radionuclides, they may also face a radiological hazard. In order to assess the risk, a granite industry with a quarry and processing factory was selected to assess the occupational exposure. Three main potential pathways were observed: external irradiation, inhalation of granite dust, and radon exposure. The external dose rate was similar to that in a nearby farming area. A slight increment (0.016-0.076 mSv yr -1 ) was observed in the quarry and stockpile, due to quarry faces and granite blocks. The effective dose due to granite dust inhalation was 0.182  ±  0.009 mSv yr -1 in the worst case scenario (3 mg m -3 dust load in air and no use of filter masks). Thus, the mean value of the effective dose from these two pathways was 0.26 mSv yr -1 , lower than the reference level of 1 mSv yr -1 for the general population. The annual mean value of radon concentration in the indoor air was 33 Bq m -3 . However, during granite processing works the radon concentration can increase up to 216 Bq m -3 , due to mechanical operations (sawing, polishing, sanding, etc). This radon concentration was below the 600 Bq m -3 reference level for action in working places. Therefore, workers in this granite factory face no significant additional radiological exposure, and no-one needs to be designated as occupationally exposed and subject to individual dosimetry.

    Rabl, A.; Spadaro, J.V.

    2005-01-01

    This article presents a synthesis of the ExternE project (External costs of Energy) of the European community about the external costs of power generation. Pollution impacts are calculated using an 'impact pathways' analysis, i.e. an analysis of the emission - dispersion - dose-response function - cost evaluation chain. Results are presented for different fuel cycles (with several technological variants) with their confidence intervals. The environmental impact costs are particularly high for coal: for instance, in France, for coal-fired power plants it is of the same order as the electricity retail price. For natural gas, this cost is about a third of the one for coal. On the contrary, the environmental impact costs for nuclear and renewable energies are low, typically of few per cent of the electricity price. The main part of these costs corresponds to the sanitary impacts, in particular the untimely mortality. In order to avoid any controversy about the cost evaluation of mortality, the reduction of the expectation of life due to the different fuel cycles is also indicated and the risks linked with nuclear energy are presented using several comparisons.

  5. Network cities and externalities

    Rafael Boix Domènech

    2004-01-01

    Full Text Available The concept of «agglomeration economies» explains the existence of advantages derived from the concentration of population and activity. However, it does not explain the existence of spatially dynamic external economies. Network economies generated in networks of cities correspond to this last type, since they are generated from the interaction between urban units, linked by a network relationship. The objective of this research is to advance in the study of the relationship between the networks of cities and the generation of external economies. The research is divided in four parts: first we expose the link between networks of cities and external economies. The second part outlines a model for the combined measuring of the concentration and network economies. The third part explains the results of applying the model to a case of study: the network of cities of Catalonia. The results suggest that there is a causal relationship between the organization of the urban units forming networks of cities and the generation of external economies that affect growth and economic development. Finally, conclusions and policy implications are drawn up.

    A collaborative approach with teachers is required when providing community-based occupational therapy to educationally at risk children. Collaborators share common goals and interact and support each other but challenges arise in providing collaborative occupational therapy in settings outside the school environment. The aim of this study was to capture experiences of teachers and occupational therapists working within a school-based occupational therapy program to determine if their experiences could inform collaborative practice. In this pilot study, participant responses to questionnaires (n = 32) about their experiences formed the basis for focus groups and individual interviews. Two focus group were conducted, one with teachers (n = 11) and one with occupational therapy participants (n = 6). Individual interviews were conducted with the supervising occupational therapist, school principal and two leading teachers. Descriptive statistics were used to analyse the data from closed questions, and thematic analysis using a constant comparison approach was used to analyse open ended questions, focus groups and interviews. Three main themes emerged: (i) the need for occupational therapists to spend time in the school, to explain their role, build relationships, understand classroom routines and the teacher role; (ii) occupational therapists need to not see themselves as the expert but develop equal partnerships to set collaborative goals and (iii) occupational therapists advocating for all parties to be informed throughout the occupational therapy process. The pilot study findings identified teacher and therapist experiences within the school setting that could inform improved collaborative practice with teachers and community-based occupational therapists and these findings warrant further investigation. © 2013 Occupational Therapy Australia.

    Full Text Available ABSTRACT Work can be an important etiologic factor in the genesis of some mental disorders including cognitive disability. Occupational neuropsychology constitutes an intriguing new but neglected area of research and clinical practice which deals with the neurocognitive consequences of the work environment and work habits. Neuropsychological knowledge is fundamental to understand cognitive requirements of work competence. Work can impact sleep patterns and mental energy, which in turn can cause neuropsychological symptoms. This report presents relevant evidence to illustrate the relationship between work and cognitive dysfunction.

    2008-12-01

    Full Text Available Zoonoses are discussed as occupational diseases, with special reference to animal husbandry and related activities. After quoting some historical references, occupational zoonoses are examined in relation to the evolution of the concept of occupational zoonosis, the involvement of the World Health Organization in this field, their socio-economic significance, the principal working activities, zoonoses of greatest importance (with special reference to the Mediterranean region, the evaluation of damage and risks. An outline is made of the transmission of zoonoses from farm workers to animals and the biological hazards from the environment. The present situation of occupational zoonoses and related risks in industrialised and traditional farming activities are presented and the importance of some emerging and re-emerging zoonoses for the health of workers is highlighted. The author concludes by stressing that the prevention of occupational zoonoses must be implemented jointly by both veterinary and medical services through preventive measures and epidemiological surveillance of human and animal health, risk evaluation, diagnosis of infections and prompt reporting. It is hoped that the future will offer better inter-disciplinary collaboration and that legislation will be timely and better tailored to safeguard working health and safety.

    Argentina is within the denominated "new industrialised countries", with the characteristic of having high contrasts in the urban population, based on service and industry, and in the rural population, based on agriculture and cattle, still the main sources of wealth in the country. The process of globalisation and the need to compete hard in international markets have provoked high unemployment and the transfer of workers from a formal market to an informal one. Legislation on occupational health is old and it is in the process of being updated. The system of prevention, assistance and compensation for accidents at work and for occupational illnesses has changed from being optative for employers, to the compulsory hiring of private insurance companies. The Government keeps the role of supervisor of the system. There are enough professionals in occupational health, hygiene and safety but not occupational nurses. The teaching is given by many universities and professional associations, some of which have an active profile in the occupational health of the country.

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

    OpenAIRE

    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.

  13. Occupational exposure to radiation in the United Kingdom and its contribution to the genetically effective dose

    Binks, W.; Marley, W.G.

    1960-01-01

    It is now the common practice in the United Kingdom for persons who are exposed occupationally to ionizing radiations to be subjected to continuous individual monitoring in order to ensure that the doses that they receive from sources external to the body do not exceed the levels which are regarded as acceptable. In the operation of large-scale monitoring services such as are provided by the Radiological Protection Service (R.P.S.) and by the establishments of the United Kingdom Atomic Energy Authority (U.K.A.E.A.) there is no satisfactory alternative to the use of photographic film, bearing in mind such aspects as simplicity, reliability, accuracy, cheapness, ease of postal transmission of the films in the special holders, and availability of a durable record of the dose received. The Radiological Protection Service provides a film badge service which is widely used by industry. This organization also provides film badges for about one-third of the occupationally exposed persons in National Health Service hospitals; for the remaining hospital workers the majority of establishments undertake their own monitoring arrangements. The United Kingdom Atomic Energy Authority provides its own film badge services for all exposed workers. It is the purpose of this report to summarize the information obtained by the R.P.S. and the U.K.A.E.A. regarding the doses received by occupationally exposed persons. The total genetically effective dose received by the population from occupational exposure is also compared with that received from natural background radiation. This report also summarizes the measurements made by the R.P.S. and the U.K.A.E.A. to check the internal contamination of the body in cases where radioactivity has been ingested or inhaled

    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.

    2017-09-01

    Within occupational therapy, it is assumed that individuals are satisfied when participating in everyday occupations that they want to do. However, there is little empirical evidence to show this. The aim of this study is to explore and describe the relation between satisfaction and participation in everyday occupations in a Swedish cohort, 5 years post stroke. Sixty-nine persons responded to the Occupational Gaps Questionnaire (OGQ). The questionnaire measures subjective restrictions in participation, i.e. the discrepancy between doing and wanting to do 30 different occupations in everyday life, and satisfaction per activity. Results were analysed with McNemar/chi-square. Seventy percent of the persons perceived participation restrictions. Individuals that did not perceive restrictions in their participation had a significantly higher level of satisfaction (p = .002) compared to those that had restrictions. Participants that performed activities that they wanted to do report between 79 and 100% satisfaction per activity. In this cohort, there was a significant association between satisfaction and participating in everyday occupations one wants to do, showing that satisfaction is an important aspect of participation and substantiates a basic assumption within occupational therapy. The complexity of measuring satisfaction and participation in everyday occupations is discussed.

    1985-01-01

    The ability to understand and appropriately apply business skills is a key component in the development of a successful private practice. Marketing is one of the business skills occupational therapists need to have in order to take full advantage of the opportunities available to entrepeneurs in the health care industry. The purpose of this article is to present a structured approach to marketing occupational therapy services through the use of a marketing plan. The four components of a marketing plan, a situation analysis, the identification of problems, opportunities, and target markets, the development of a marketing strategy for each targeted market, and a method to monitor the plan, are discussed. Applications to occupational therapy practice are suggested. The use of a marketing plan as a method for organizing and focusing marketing efforts is an effective means of supporting and enhancing the development of a private practice.

    World Federation of Occupational Therapists

    2014-09-01

    Full Text Available The purpose of this document is to state the World Federation of Occupational Therapists’ (WFOT position on the use of telehealth for the delivery of occupational therapy services. Telehealth is the use of information and communication technologies (ICT to deliver health-related services when the provider and client are in different physical locations. Additional terms used to describe this service delivery model include: tele-occupational therapy, telerehabilitation, teletherapy, telecare, telemedicine, and telepractice, among other terms. Telehealth may be used by occupational therapy practitioners for evaluation, intervention, monitoring, supervision, and consultation (between remote therapist, client, and/or local health-care provider as permitted by jurisdictional, institutional, and professional regulations and policies governing the practice of occupational therapy.Occupational therapy services via telehealth should be appropriate to the individuals, groups and cultures served,and contextualized to the occupations and interests of clients. Important considerations related to licensure/registration, collaboration with local occupational therapists, client selection, consent to treat, professional liability insurance, confidentiality, personal and cultural attributes, provider competence/standards of care, reimbursement/payer guidelines, and authentic occupational therapy practice are discussed.

    Disclosed are microcapsules comprising a polymer shell enclosing one or more immiscible liquid phases in which a drug or drug precursor are contained in a liquid phase. The microparticles also contain magnetic particles that can be heated by application of an external magnetic field and thus heated to a predetermined Curie temperature. Heating of the particles melts the polymer shell and releases the drug without causing heating of surrounding tissues.

    Fibromyalgia (FM) is a clinical syndrome commonly observed in daily medical practice and its etiopathogenesis is still unclear. As it is characterized by chronic musculoskeletal pain associated with several symptoms, FM may be confused with several other rheumatic and nonrheumatic diseases when they course with pictures of diffuse pain and chronic fatigue. FM treatment should be multidisciplinary, individualized, count on active participation of the patient, and based on combined pharmacological and nonpharmacological modalities. It is found both in work and non-work settings, and there is no scientific evidence in the literature showing that FM might be caused by occupation. FM seldom leads to incapacity to work. In cases where pain or fatigue do not respond to appropriate treatment, reaching significant levels, a short period away from work can be considered. As FM is a relevant subject, this review article was based on exploratory, qualitative, and bibliographic investigation, aiming to study the main clinical and occupational aspects of FM, emphasizing the theoretical-conceptual background and the experience of specialists.

  5. Occupational dose trends in Tanzania

    This paper describes the present status of occupational radiation exposure of monitored workers in Tanzania from 1986 to 1997. The analysis of dose records observes over this period, a fluctuating trend both in the individual and collective doses. The trend is more related to the fluctuations of the number of radiation workers than to the possible radiation safety changes of the working conditions. It has been found that, the maximum annual dose for the worker in all work categories was about 18 mSv y -1 . This suggests that the occupational radiation exposure in all practices satisfies the current dose limitation system. The national exposure summary shows that, the highest collective dose of 12.8 man-Sv which is 90% of the total collective dose, was due to medical applications. The applications in industry and research had a contribution of nearly 0.8 and 0.7 man-Sv respectively. From the professional point of view, the medical diagnostic radiographers received the highest collective dose of 11.2 man-Sv. Although the medical physicists recorded the minimum collective dose of nearly 0.07 man-Sv, the data shows that this profession received the highest mean dose of about 33 mSv in 12 years. Some achievements of the personnel monitoring services and suggestions for future improvement are pointed out. (author)

    Socio-economic position measures, such as education, occupational class and income, are well-known determinants of health. However, previous studies have not paid attention to mutual interrelationships between these socio-economic position measures and medically confirmed sickness absence. The study is a register-based study. The participants were municipal employees of the City of Helsinki aged 25-59 years in 2003. There were 21,599 women and 5841 men participants. Three socio-economic position measures were used, namely three-level education, four-level occupational class and gross individual income quartiles. Main outcome measure was medically confirmed sickness absence spells of 4 days or longer. Inequality indices were calculated using Poisson regression analysis. High education, occupational class and individual income were all consistently associated with lower sickness absence rates among both women and men. After mutual adjustment, education and occupational class remained independent determinants of sickness absence. The association of individual income with sickness absence was practically explained by temporally preceding education and occupational class. Our results indicate that education and occupational class-rather than income-are strong determinants of sickness absence. Education, occupational class and income are complementary socio-economic position measures. To better inform sickness absence policy, future studies should aim to establish whether the observed socio-economic differences reflect broader differences in ill-health, lifestyle and working conditions.

  9. Under-use of body energy and over-use of external energy

    The world's affluent countries, such as the EU, are facing two severe problems with long-term consequences. One problem is the epidemic-like increase in adverse health effects, which are related to the increasing wealth, primarily appearing as obesity and its associated diseases. This is caused by overeating and under-use of the body energy, due to increased use of mechanized and energy consuming assistance for transport and other daily tasks. This connects to the other problem, namely these countries' excessive use of fossil fuels and other environmentally harmful forms of nature's external energy. This paper illuminates the options for integrated solutions to the two problems by making more use of body energy as a means to reduce the use of nature's external energy. First is listed a human's body energy used for various tasks and occupations, showing that a person's use of external energy is an order of magnitude higher, which can be expressed by the scores of 'energy slaves' each citizen utilizes. An extra health driven physical effort by humans seems to have negligible direct impact on energy consumption. The paper will, however, indicate examples of significant indirect savings of external energy, achieved by healthy extra human efforts. Also, the paper will suggest ways to integrate energy saving policies with health policies for organizing and designing cities and houses to be 'healthy inconvenient', encouraging or pushing people to use their body in their daily doings. This is an enormous challenge to the conventional way of thinking among architects, engineers, planners, as well as individuals in general.

    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.

    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.

  19. Occupation, well-being, and culture: Theory and cultural humility.

    Hammell, Karen R Whalley

    2013-10-01

    The Canadian Model of Occupational Performance and Engagement depicts individuals embedded within cultural environments that afford occupational possibilities. Culture pertains not solely to ethnicity or race but to any dimension of diversity, including class, gender, sexual orientation, and ability. This paper highlights specific dimensions of cultural diversity and their relationships to occupational engagement and well-being. Cultural variations constitute the basis for a socially constructed hierarchy of traits that significantly determine occupational opportunities and impact mental health and well-being. Cultural humility is an approach to redressing power imbalances in client-therapist relationships by incorporating critical self-evaluation and recognizing that cultural differences lie not within clients but within client-therapist relationships. It is proposed that theoretical relevance would be enhanced if culturally diverse perspectives were incorporated into theories of occupation. Cultural humility is advocated as an approach to theoretical development and in efforts to counter professional Eurocentrism, ethnocentrism, and intellectual colonialism.

    Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's (AOTA's) Evidence-Based Practice Project. In this Evidence Connection article, we describe a case report of an adolescent with autism spectrum disorder. The occupational therapy assessment and treatment processes for school, home, community, and transition settings are described. Findings from the systematic reviews on this topic were published in the September/October 2015 issue of the American Journal of Occupational Therapy and in AOTA's Occupational Therapy Practice Guidelines for Individuals With Autism Spectrum Disorder. Each article in this series summarizes the evidence from the published reviews on a given topic and presents an application of the evidence to a related clinical case. Evidence Connection articles illustrate how the research evidence from the reviews can be used to inform and guide clinical decision making.

    Full Text Available Visual characteristics, including facial appearance, are thought to play an important role in a variety of judgments and decisions that have real occupational outcomes in many settings. Indeed, there is growing evidence suggesting that appearance influences hiring decisions and even election results. For example, attractive individuals are more likely to be hired, taller men earn more, and the facial appearance of candidates has been linked to real election outcomes. In this article, we review evidence linking physical appearance to occupational success and evaluate the hypothesis that appearance based biases are consistent with predictions based on evolutionary theories of coalition formation and leadership choice. We discuss why appearance based effects are so pervasive, addressing ideas about a “kernel of truth” in attributions and about coalitional psychology. We additionally highlight that appearance may be differently related to success at work according to the types of job or task involved. For example, leaders may be chosen because the characteristics they possess are seen as best suited to lead in particular situations. During a time of war, a dominant-appearing leader may inspire confidence and intimidate enemies while during peace-time, when negotiation and diplomacy are needed, interpersonal skills may outweigh the value of a dominant leader. In line with these ideas, masculine-faced leaders are favored in war-time scenarios while feminine-faced leaders are favored in peace-time scenarios. We suggest that such environment or task specific competencies may be prevalent during selection processes, whereby individuals whose appearance best matches perceived task competences are most likely selected, and propose the general term “task-congruent selection” to describe these effects. Overall, our review highlights how potentially adaptive biases could influence choices in the work place. With respect to certain biases

    1975-01-01

    Because the medical use of x-rays and radioisotopes is gradually increasing for diagnosis and therapy, radiation workers, special doctors, nurses and radiological technicians have occupational exposure. Procedures for monitoring external exposure of personnel include the wearing of a filmbadge or a pocket chamber. The results of filmbadge monitoring in Yamaguchi University Hospital for the last 10 years were described. In 1964, the total number of filmbadges that radiation workers used during a 2 week period of radiological examination and therapy was 610. This has been increasing yearly, and in 1972 it was 1999. Radiological technicians generally had low occupational exposure, and about 90 per cent of their filmbadges were exposed to less than 10 mR. Approximately 65 per cent of the filmbadges that nurses used were less than 10 mR, but some nurses who worked in radium therapy at the isotope ward suffered large doses. Some nurses had occasionally exposure higher than 100 mR in radiological examination. Some doctors sustained an occupational exposure of more than 150 mR. From these data, some problems on radiation monitoring using a filmbadge were discussed. (author)

    Occupational exposure to extremely low frequency (ELF) magnetic fields (MF) in the UK general population is poorly documented. To assess levels of occupational exposure to ELF MF in the UK and evaluate the use of a rigid job-exposure matrix (JEM) to assign exposures to subjects in the UK Adult Brain Tumour Study (UKABTS). Personal ELF MF measurements were carried out. Exposure traces were divided into occupational, travel and elsewhere periods, under differing exposure metrics. Exposure was classified by Standard Occupational Classification (2000), Standard Industrial Classification (1997), and a combined occupation-industry classification. Statistical analyses (mixed effects model) determined the contribution of occupational exposure to the 24 h cumulative exposure and the contribution of occupation and industry to total variance. Data were obtained from 317 individuals, comprising UKABTS subjects (n = 192), occupational proxies for UKABTS subjects (n = 101) and "interest" readings (n = 24). 236 individuals provided occupational data covering 117 different occupations. Average exposure was significantly higher at work than at home. Elevated average occupational exposure was found for welding trades, printers, telephonists and filing and other records assistants. The discrimination of a rigid JEM based on occupation can be improved by linking the classification with industry and by the use of contextual information. This report substantially expands information on adult exposure to ELF MF in the UK. The accuracy of exposure assessments based solely on job codes is improved by linking with either industry code or contextual knowledge of equipment and of power lines or substations in the work environment.

  10. Exploring the nexus between health promotion and occupational therapy: synergies and similarities.

    2014-06-01

    The similarities between health promotion and occupational therapy have been recognized. Both are based on perspectives that share a goal of enabling individuals and populations to improve control over their health. Consequently, it is logical that the principles of health promotion complement the practice of occupational therapy. This paper highlights the affinity between occupational therapy and health promotion, and discusses ways in which health promotion principles can be incorporated into occupational therapy practice. Some Canadian occupational therapists may be unaware of the current discourse in health promotion and, thus, may not be incorporating its principles into practice. Steps are warranted to expand the current knowledge and practice of therapists to include health promotion, with specific attention to providing services for the population. Incorporating health promotion principles into occupational therapy perspectives will facilitate the implementation of the domains of practice within the occupational therapy profile. This paper highlights how the principles of health promotion can impact practice at the individual and community level.

    Full Text Available Obesity is a worldwide phenomenon that affects both the rich and poor populations. It results from the action of environmental factors, dietary habits, physical activity and psychological conditions on individuals genetically predisposed to present excess adipose tissue. The impact of obesity can be measured by its influence on the quality of life. Occupational therapy has developed a significant role within the interdisciplinary treatment of obesity. The objective of this paper is to describe the experience of the work of occupational therapists in an interdisciplinary group for adult and elderly people presenting overweight and obesity in an extension project of a private university in Natal, Rio Grande do Norte state. The Occupational Therapy team performed weekly interdisciplinary care, assessment, planning, organization of the therapeutic setting and occupational therapy intervention. The team was composed by an occupational therapy teacher, a scholar and five volunteer undergraduate students. The service group was open to new components, caregivers, and family and community members. Playful, cognitive, bodily, physical and productive occupational therapy activities were used in the sessions. These activities favored positive outcomes in mental, emotional and social dimensions. Thus, the project enabled the visibility of Occupational Therapy at the university, as well as the growth and expansion of academic and occupational knowledge on therapeutic intervention in obesity.

    Food industry workers are at increased risk for occupational contact urticaria (CU). There are many foodstuffs that have been reported to cause occupational CU, including seafood, meat, vegetables, and fruits. The aim of this review is to summarize all reported occupational cases of CU in the food industry. This is a systematic review based on a MEDLINE search of articles in English and German and a manual search, between 1990 and 2014, to summarize the case reports and case series of occupational CU in the food industry. Many different foodstuffs have been implicated in CU. Occupational CU has been reported in many different occupations, mostly in individuals dealing with seafood, meat, vegetables, and fruits, such as chefs, cooks, bakers, butchers, slaughterhouse workers, and fish-factory workers. Foodstuffs that commonly induce occupational protein contact dermatitis include fish, seafood, meats, vegetables, and fruits. Food handlers may acquire CU resulting from occupational exposures. The prognosis varies widely. The diagnosis of immunological CU is based on the clinical history and on a positive prick test with the suspected substance and/or measurement of specific IgE. © 2016 John Wiley & Sons A/S.

    Full Text Available The present study aims at identifying how the everyday life concept is used in the Occupational Therapy field in the English language literature and at making considerations in relation to the Brazilian literature on the subject. A systematic review of the international literature on the everyday life concept in the Occupational Therapy field was carried out and, from the results of this phase, reflections about the differences and similarities noticed in the use of this concept in the field of occupational therapy in Brazil are presented. Twenty articles selected from the CAPES (Coordination for the Improvement of Higher Education Personnel database were elected for analysis. This analysis found that English speaking authors, on the issue of everyday life rupture, focus on the assistance needed to help individuals to be able to perform their former occupations in an autonomous way. Besides, the way people live their everyday lives is an element that constitutes the person’s identity; people become what they are from their occupations. Everyday life is described in occupational terms; it is understood by the meaningful things people do in their lives. It is pointed out that, as opposed to the national literature, the international literature does not focus on the connection between everyday life and the social-political-cultural context. Thus, we discuss that the understanding about the contextualized everyday life is shared with Brazilian occupational therapists, and it has the potential to be presented as a construct on which the Brazilian contemporary occupational therapy identity is built.

  14. DOE occupational radiation exposure. Report 1992--1994

    The DOE Occupational Radiation Exposure Report, 1992-1994 reports occupational radiation exposures incurred by individuals at US Department of Energy (DOE) facilities from 1992 through 1994. This report includes occupational radiation exposure information for all DOE employees, contractors, subcontractors, and visitors. This information is analyzed and trended over time to provide a measure of the DOE's performance in protecting its workers from radiation. Occupational radiation exposure at DOE has been decreasing over the past 5 years. In particular, doses in the higher dose ranges are decreasing, including the number of doses in excess of the DOE limits and doses in excess of the 2 rem Administrative Control Level (ACL). This is an indication of greater attention being given to protecting these individuals from radiation in the workplace

    The recent situation in the Czech Republic (CZ) concerning the evaluation and recording of occupational radiation exposures is described. The individual monitoring is based on the interpretation of the personal dosemeters responses and the evaluation of the other special dosimetric methods (measurement of excrete, whole body counting, etc.). The evaluation of occupational radiation exposures is carried out by five approved dosimetric services, which control about 20,000 workers. Record keeping of overexposures is based on two systems, which principles are explained. Based on long time analysis of occupational radiation exposures in CZ it can be present that the average values and trends of individual and collective effective dose equivalents are comparable with those in developed countries. The distributions of the radiation exposures for the important occupational groups of workers are presented. (author)

    In Denmark, the practice of occupational medicine tends to be carried out by specialists in occupational medicine and less so by family physicians. The provision of health service to workers is therefore limited. This constraint may also apply in other developed countries and even more in countries...... with few occupational health resources. This Editorial argues that family physicians are indeed in a position where they can make a major positive difference for their working patients and for the enterprises where they work.

    2010-10-01

    Full Text Available In this article we propose to study occupational careers with historical data by using multilevel growth models. Historical career data are often characterized by a lack of information on the timing of occupational changes and by different numbers of observations of occupations per individual. Growth models can handle these specificities, whereas standard methods, such as event history analyses can't. We illustrate the use of growth models by studying career success of men and women, using data from the Historical Sample of the Netherlands. The results show that the method is applicable to male careers, but causes trouble when analyzing female careers.

    The institute for Radiation Protection of ENEA - Bologna has organised a one day-workshop on the subject: Individual monitoring of external exposure in terms of personal dose equivalent, H{sub p}(d). The aim of the workshop was the discussion of the new implications and modifications to be expected in the routine individual monitoring of external radiation, due to the issue of the Decree 241/00 (G.U. 31/8/2000) in charge since 01/01/2001. The decree set up in Italian law the standards contained in the European Directive EURATOM 96/29-Basic Standards for the Protection of Health of Workers and the General Public against Dangers arising from Ionizing Radiation. Among others, the definition of the operational quantities for external radiation for personal and environmental monitoring, H{sub p}(d) e H{sup *}(d) respectively as defined by ICRU (International Commission for Radiation Units and Measurements), requires to update the methods of measurements and calibration of the personal dosemeters and environmental monitors. This report collects the papers presented at the workshop dealing with the Personal Dose Equivalent, H{sub p}(d), the conversion coefficients, H{sub p}(d)/K{sub a} e H{sub p}(d)/{sub ,} obtained through Monte Carlo calculations published by ICRU and ICRP (International Commission for Radiation Protection), the new calibration procedures and the practical implication in the routine of individual monitoring in terms of H{sub p}(d).

    Full Text Available The research developed in this paper is based on micro data available in Programme for the International Assessment of Adult Competencies (PIAAC. The research aimed to estimate the size of both forms of labour market mismatch: education mismatch and skill mismatch. The first measure of job mismatch is based on workers’ self-assessment. The second one uses the PIAAC assessment regarding the proficiency for each skill dimension (literacy, numeracy and problem solving in technology rich environments. The labor market mismatch was measured for Spain and Italy datasets for the higher education graduates whose occupations are included in Major Group two Professionals, according to the International Standard Classification of Occupations. The estimation results showed that the two measures of labour market mismatch are not correlated.

    Background: Motivation is one of the most important factors for safety behaviour and for implementing change in general. However, theoretical and psychometric studies of safety performance have traditionally treated safety motivation, safety compliance and safety participation unidimensionally....... At the same time many motivation questionnaire items are seldom founded on theory and/or do not account for the theories’ ontological and epistemological differences, e.g. of how knowledge, attitude and action are related. Present questionnaire items tap into occupational safety motivation in asking whether...... or not respondents ‘are’ motivated and whether they feel that safety is important or worthwhile. Another important aspect is ‘what’ motivates workers to comply to and participate in safety. The aim of this article is to introduce a new theory-based occupational safety motivation scale which is validated...

  5. Dose estimation and radiation control measures for individuals having close contact with patients administered in vivo nuclear medicine

    Konishi, E.; Abe, K.; Kusama, T.

    1993-01-01

    Patients who have been administered radiopharmaceuticals become a source of exposure to a non-occupational individual helping in support and comfort of these patients. We measured external dose rates at several distances from 84 adult patients administered radiopharmaceuticals, and urinary excretion of radioactivity in their patients. And we estimated the maximal dose for persons having close contact with patients administered radiopharmaceuticals from the combination of these measurement data and scenarios of contact with patients. On the basis of the estimated values, we proposed the following dose constraint for care givers. (1) The dose constraint for a non-occupational care givers to an adult nuclear medicine patient should in no case exceed 300 μSv per patient per examination of any kind. (2) The dose constraint in ordinary examinations employing a radionuclide should not be greater than 15 μSv per patient per examination. (3 tabs.)

    Full Text Available Jen Gash, an occupational therapist and creativity coach living in the UK, provided the cover art for the winter 2015 issue of The Open Journal of Occupational Therapy. The picture is titled “Over the Exe.” Jen uses her inspiration of the Kawa River model in this painting. The painting is of her husband and daughter standing where the river meets the sea. This is a metaphoric representation of rejoining the greater collective. In addition, Jen has a passion for occupational therapists to encompass creativity. A core aspect of occupational therapy is the multi-dimensional concept of occupations; it allows for occupational therapists to incorporate creativity into daily practice. Jen’s goal is for occupational therapy to embrace its creative theoretical roots.

  8. Perspective on occupational mortality risks

    International Nuclear Information System (INIS)

    Cohen, B.L.

    1981-01-01

    Occupational risks to radiation workers are compared with other occupational risks on the basis of lost life expectancy (LLE) in a full working lifetime. Usual comparisons with National Safety Council accident death statistics for various industry categories are shown to be unfair because the latter average over a variety of particular industries and occupations within each industry. Correcting for these problems makes some common occupations in some industries 20-50 times more dangerous due to accidents alone than being a radiation worker. If more exposed subgroups of radiation workers are compared with more dangerous subgroups of other occupations, these ratios are maintained. Since radiation causes disease rather than acute injury, a wide range effort is made to estimate average loss of life expectancy from occupational disease; the final estimate for this is 500 days. The average American worker loses more than an order of magnitude more life expectancy from occupational disease than the average radiation worker loses from radiation induced cancer. (author)

  11. 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.

    In the period of transition from a centralized economy to the market economy, occupational health services in Kyrgyzstan have survived through dramatic, detrimental changes. It is common for occupational health regulations to be ignored and for basic occupational health services across many industrial enterprises and farms to be neglected. The aim of this study was to demonstrate the present situation and challenges facing occupational health services in Kyrgyzstan. The transition from centralized to the market economy in Kyrgyzstan has led to increased layoffs of workers and unemployment. These threats are followed by increased workload, and the health and safety of workers becomes of little concern. Private employers ignore occupational health and safety; consequently, there is under-reporting of occupational diseases and accidents. The majority of enterprises, especially those of small or medium size, are unsanitary, and the health status of workers remains largely unknown. The low official rates of occupational diseases are the result of data being deliberately hidden; lack of coverage of working personnel by medical checkups; incompetent management; and the poor quality of staff, facilities, and equipment. Because Kyrgyzstan is a mountainous country, the main environmental and occupational factor of enterprises is hypoxia. Occupational health specialists have greatly contributed to the development of occupational medicine in the mountains through science and practice. The enforcement of existing strong occupational health legislation and increased financing of occupational health services are needed. The maintenance of credible health monitoring and effective health services for workers, re-establishment of medical services and sanitary-hygienic laboratories in industrial enterprises, and support for scientific investigations on occupational risk assessment will increase the role of occupational health services in improving the health of the working population

    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.

    Full Text Available BACKGROUND Immigration from Africa to Europe has increased substantially in recent decades. The main goal of this paper is to contribute to a better understanding of contemporary international migration processes by analyzing the occupational trajectories and occupational costs of Senegalese immigrants in three major European destination countries (France, Italy, and Spain. OBJECTIVE The first objective is to compare the occupational attainment of the Senegalese immigrants before and after migration to Europe, as well as to establish the determinants of the immigrants' occupational attainment and occupational mobility levels after migration. Another major goal is to estimate the occupational cost of migration from Senegal to Europe. The central question this study intends to answer is how much, in terms of occupational status, Senegalese immigrants renounce by migrating to Europe, in both the short and the long term. METHODS The data stem from the Senegalese sample of the MAFE dataset. The standard OLS techniques are used in the analysis of occupational attainment, while discrete-time multinomial logit is used in the section on occupational mobility. The principal techniques for the estimation of occupational cost of migration are random effects with Mundlak correction and nearest-neighbor matching. RESULTS There is a U-shaped pattern of occupational mobility among Senegalese immigrants in Europe: the average occupational status of this group drops just after arrival in Europe, and then slowly improves with the duration of stay. The multivariate analysis reveals that education acquired in Europe plays an especially important role in the successful participation of this immigrant group in the labor market. The results show that there is a statistically significant occupational cost of migration from Senegal to Europe, but that the cost decreases with the duration of stay in Europe.

    Darius, S; Meyer, F; Böckelmann, I

    2016-11-01

    Surgeons routinely work in an environment with occupational risks and hazards about which they are often uninformed. Based on the currently available scientific literature this review article describes the various hazards in the operating theater and their effects on personnel, particularly from the surgical perspective. A further aim of this article is to describe the occupational safety measures to reduce the burdens and to maintain the long-term health of personnel. Ultimately, surgeons should be equipped with the necessary knowledge for implementing hazard assessments according to the German Occupational Health and Safety Act. Surgeons are exposed to increased risks and hazards by working in awkward positions with a high risk for musculoskeletal pain and injuries. They are also commonly exposed to inhalational anesthetics, surgical smoke, radiation, noise and infectious agents. Furthermore, the mental and emotional stress associated with these activities is also high. Meaningful occupational safety measures for reduction of burdens are from a technical aspect the installation of effective air extraction systems, measures to reduce exposure to radiation and noise and the use of safer instruments to prevent needle stick injuries. Furthermore, individual occupational safety measures, such as the use of personal protective equipment (e.g. radiation protective clothing and double gloves) must be observed. The consistent implementation and also adherence to these described occupational safety measures and regulations can reduce the burden on operating theater personnel and contribute to maintaining health. Furthermore, periodic preventive healthcare controls and health checks by the company medical officer and individually initiated additional prevention measures can be a sensible augmentation to these safety measures.

    To assess the risk of renal dysfunction caused by occupational lead exposure through epidemiological investigation. The workers in a battery factory were selected as the subjects for the exposure and effect assessment. The occupational environmental monitoring data was collected and used to calculate the total external dose of lead. The relationship between external dose and internal dose of lead was analyzed. The external dose, blood lead (BPb) and urinary lead (UPb) were used as exposure biomarkers while the urinary N-acetyl-D-glucosaminidase (UNAG), and urinary albumin (UALB) were used as the effect biomarkers for the renal dysfunction caused by lead. Software of BMDS (BMDS 11311) was used to calculate BMD. The external and internal does of lead was positively correlated (BPb: r = 0.466, P < 0.01; UPb: r = 0.383, P < 0.01). The levels of BPb, UPb in exposure group (654.03 microg/L, 143.45 microg/g Cr) were significantly higher than those in the control group (57.12 microg/L, 7.20 microg/g Cr), so were UALB, UNAG; in addition, all of them presented significant dose-response relationship. The BPb BMD of UALB, UNAG were 607.76, 362.56 microg/L respectively and the UPb BMD of UALB, UNAG were 117.79, 78.79 microg/gCr respectively. Occupational lead exposure can cause renal dysfunction, which presents dose-response relationship; the risk assessment of renal dysfunction caused by occupational lead exposure is performed by BMD calculation of BPb and UPb.

    The Radioactive Waste Laboratory (RWL) of IPEN-CNEN/SP receives, treats, packs, characterizes and stores institutional radioactive wastes, in their physical forms solid, liquid or gaseous and sealed radioactive sources, with the objective to assure an adequate level of protection to the population and to future generations and the preservation of environment. Since its creation, RWL has already received and treated about one thousand cubic meter of solid waste, eight thousand spent sealed radioactive sources from practices in industry, medicine and research, totaling more than 100 TBq. In addition, fifteen thousand radioactive lightning rods and twenty two thousand radioactive smoke detectors were received. The activities accomplished in RWL, as dismantling of lightning rods, compaction of solid wastes, decontamination of objects, waste characterization, treated waste packages rearrangement, among others, cause risks of intake and/or external exposure of workers. Requirements of radiological safety established in the regulations of the nuclear authority and international recommendations are consolidated in the RWL radioprotection plan in order to ensure the safety and protection of workers. In this paper, it was evaluated if the procedures adopted were in accordance with the requirements established in the radioprotection plan. It was also studied which activities in the waste management had substantial contribution to the occupational doses of the RWL workers in the period from 2001 up to 2006. For that, the radioprotection plan, the operational and safety procedures, the records of workplace monitoring and the individual dose reports were analyzed. It was observed that the highest individual doses resulted from operations of treated waste packages rearrangement in the facility, and none of the workers received doses above the annual limit.

    This work aims to develop and establish a methodology for in vivo internal monitoring at individuals occupationally exposed (IOE) to F-18 in form of F-18DG at the DIPRA/CRCN-NE. The detection system used was the NaI(Tl) 3' x 3', coupled with the software Genie 2000. The measurements performed with the brain phantom were used to obtain the Calibration Factor. The bioassay data interpretation was performed through software AIDE, using the F-18DG biokinetic model available in ICRP 53 publication. The MDED obtained was compared to the value of the recording level, 1 mSv, recommended by IAEA in order to validate the technique. During two days of F-18DG productions, there were performed in vivo measurements of the IOE at DIPRA/CRCN-NE. The methodology developed demonstrated sufficient sensitivity for detect MDED of 76 n Sv. The results of the in vivo measurements demonstrated that all IOE from CRCN/NE obtained doses below MDED. (author)

The number of monitored industrial radiography facilities ranged from 7 to 14 while the number of worker ranged from 72 to 133 during the study period. The annual average effective doses received from external radiation in industrial radiography workers and the distributions of the annual effective doses by dose intervals are presented. The distribution of the occupational doses shows that the majority (about 75 %) of workers received doses below 1 mSv for the last 5-years. Even though, very few workers (about 1%) received doses higher than average annual dose limit (20 mSv), but no workers received doses higher than 100 mSv in 5 consecutive years. The average annual effective dose of industrial radiography workers in Bangladesh is higher than the corresponding values in Tanzania, Greece, Poland, Australia, UK and lower than in Bosnia and Herzegovina, USA and Canada. However, the average annual effective dose is comparable to the corresponding values in China, Brazil, Germany and India. The status and trends in occupational doses show that radiation protection situation at the majority of the workplace were satisfactory. In spite of that, additional measures are required due to big differences observed in the maximum individual doses over the last 5-year. (author)

  1. Case-control study of congenital malformations and occupational exposure to low-level ionizing radiation

    In a case-control study, the authors investigated the association of parental occupational exposure to low-level external whole-body penetrating ionizing radiation and risk of congenital malformations in their offspring. Cases and controls were ascertained from births in two counties in southeastern Washington State, where the Hanford Site has been a major employer. A unique feature of this study was the linking of quantitative individual measurement of external whole-body penetrating ionizing radiation exposure of employees at the Hanford Site, using personal dosimeters, and the disease outcome, congenital malformations. The study population included 672 malformation cases and 977 matched controls from births occurring from 1957 through 1980. Twelve specific malformation types were analyzed for evidence of association with employment of the parents at Hanford and with occupational exposure to ionizing radiation. Two defects, congenital dislocation of the hip and tracheoesophageal fistula, showed statistically significant associations with employment of the parents at Hanford, but not with parental radiation exposure. Neural tube defects showed a significant association with parental preconception exposure, on the basis of a small number of cases. Eleven other defects, including Down syndrome, for which an association with radiation was considered most likely, showed no evidence of such an association. When all malformations were analyzed as a group, there was no evidence of an association with employment of the parents at Hanford, but the relation of parental exposure to radiation before conception was in the positive direction (one-tailed p value between 0.05 and 0.10). Given the number of statistical tests conducted, some or all of the observed positive correlations are likely to represent false positive findings. 30 references

    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.

    Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

    1994-01-01

    The EC/US study of the external costs of fuel cycles is designed to trace through all the environmental impacts arising from the use of a particular fuel, from the 'cradle' to the 'grave'; to quantify these impacts as far as possible (giving priority to those that are the considered the most important) and to value the damages arising from them in money terms as far as possible (again keeping to the priority listing established by the physical quantification). The fuel cycle has been identified as consisting of the following elements: activities -> emissions/burdens; emissions/burdens -> physical environmental impacts; physical impacts -> external environmental impacts; external impacts -> costs of these impacts. The activities consist of all the operations that are carried out in connection with the extraction transportation, use in electricity generation and finally disposal of the fuel. The emissions or burdens arising from the cycle result in physical impacts, which in turn imply certain environmental impacts. An illustration of a typical fuel cycle (coal) audits environmental impacts is given in Figures. The work of the fuels cycle study teams is to complete the valuation of the shaded areas but giving priority to those impacts that are likely to be quantitatively important. .Each fuel cycle is evaluated in a location-specific context, so that it refers to the impacts arising from the use of coal, or gas or whatever fuel is being considered at an actual plant that is operating. The purpose of this report on economic valuation is to: (a) examine the literature or economic valuation of environmental externalities in Europe; (b) assess its relevance to the fuel cycle study and (c) make recommendations on how the detailed analysis of the individual fuel cycles should use the economic valuation. It is important to recognize that the report is not a complete survey of all the research ever done on environmental valuation. Although as complete a survey of all the

    What, if anything, is wrong with gentrification? This paper addresses this question from the perspective of normative political theory. We argue that gentrification is a wrong insofar as it involves a violation of city-dwellers occupancy rights. We distinguish these rights from other forms...... of territorial rights, and discuss the different implications of the argument for urban governance. If we agree on the ultimate importance of being able to pursue one’s located life-plans, the argument goes, we must also agree on limiting the impact on gentrification on people’s lives.

Witz described a credentialist approach to occupational closure adopted by nursing in the United Kingdom during the 19th and early 20th centuries. However, the recent advancement...... boundaries and a usurpatory stance towards these boundaries. Participants had usually been handpicked by managers and some were ambitious and confident in their abilities. Many aspired to train to be nurses claiming that they will gain recognition that they do not currently get but which they deserve....... Their scope of practice is based upon their managers' or supervisors' perception of their individual aptitude rather than on a credentialist claim.

    A change from a quarter system to a semester system presented a convenient opportunity for faculty at the Midwest Center for Occupational Health and Safety (a 27-year-old National Institute for Occupational Safety and Health-sponsored education and research center) to evaluate the current curriculum. As part of this process faculty identified both individual and crosscutting competencies for four programs: Occupational Medicine, Occupational Health Nursing, Industrial Hygiene, and Occupational Injury Epidemiology and Control. Faculty identified potential competency sets using published literature, course objectives, and content summaries. Common themes, termed crosscutting competencies, were identified. Seventy program graduates (58%) responded to a survey designed to assess the value of, and proficiency in, these competencies based on their postgraduation job experience. All 29 crosscutting competencies were rated as valuable or very valuable by respondents in each of the four programs. There was less agreement between respondents in proficiency ratings, with 24 of 29 competencies rated either proficient or very proficient. Comparing value and proficiency provided an opportunity to further refine the curriculum and a model for enhancing the skills, knowledge, and attitudes of future environmental and occupational health professionals. With further testing, we propose this set of crosscutting competencies be considered for adoption as a set of interdisciplinary core competencies for Occupational Health and Safety professionals.

  3. An overview of low back pain and occupational exposures to whole-body vibration and mechanical shocks.

    This paper offers an overview of the relation of low back pain (LBP) to occupational exposures to whole-body vibration (WBV) and mechanical shocks. LBP is a condition of multifactorial origin and is a very common health problem in the general population. Among occupational risk factors, epidemiological studies of driving occupations have provided evidence for strong associations between LBP and occupational exposures to WBV and mechanical shocks. Since it is hard to separate the contribution of WBV exposure to disorders in the lower back from that of other individual, ergonomic or psychosocial risk factors, a quantitative exposure-response relationship for WBV cannot be outlined precisely. Experimental research has provided biodynamic support to the findings of epidemiological studies, showing that in controlled laboratory conditions exposure to WBV can cause mechanical overload to the human spine. The EU Directive on mechanical vibration has established daily exposure action and limit values to protect the workers against the risk from WBV. There is some evidence that the EU exposure limit values are excessive, so much so that an elevated risk of LBP has been found for WBV exposures beneath the EU limit values. In the Italian arm of the EU VIBRISKS prospective cohort study of professional drivers, measures of internal lumbar load (compressive and shear peak forces), calculated by means of anatomy-based finite-element models, were found better predictors of the occurrence over time of low back disorders than the metrics of external exposure suggested by the EU Directive on mechanical vibration. Further biodynamic and epidemiological studies are needed to validate the findings of the VIBRISKS study.

    Patient safety climate/culture is attracting increasing research interest, but there is little research on its relation with organizational climates regarding other target domains. The aim of this study was to investigate the relationship between patient safety climate and occupational safety climate in healthcare. The climates were assessed using two questionnaires: Hospital Survey on Patient Safety Culture and Nordic Occupational Safety Climate Questionnaire. The final sample consisted of 1154 nurses, 886 assistant nurses, and 324 physicians, organized in 150 work units, within hospitals (117units), primary healthcare (5units) and elderly care (28units) in western Sweden, which represented 56% of the original sample contacted. Within each type of safety climate, two global dimensions were confirmed in a higher order factor analysis; one with an external focus relative the own unit, and one with an internal focus. Two methods were used to estimate the covariation between the global climate dimensions, in order to minimize the influence of bias from common method variance. First multilevel analysis was used for partitioning variances and covariances in a within unit part (individual level) and a between unit part (unit level). Second, a split sample technique was used to calculate unit level correlations based on aggregated observations from different respondents. Both methods showed associations similar in strength between the patient safety climate and the occupational safety climate domains. The results indicated that patient safety climate and occupational safety climate are strongly positively related at the unit level, and that the same organizational processes may be important for the development of both types of organizational climate. Safety improvement interventions should not be separated in different organizational processes, but be planned so that both patient safety and staff safety are considered concomitantly.

    Mugwort (Artemisia vulgaris) has traditionally been used as a spice, vegetable and as a herbal medicine. The main representatives of the Artemisia family besides Artemisia vulgaris include Artemisia absinthum and Artemisia dracunculus (estragon). Mugwort pollen allergens are important in triggering late summer and fall pollinosis; in addition cross reactivity occurs between Artemisia vulgaris pollen allergens and celery, carrottes and certain spices belonging to the family of Umbelliferae. A florist with a pre-existing sunflower allergy developed a life-threatening glottal edema after occupational contact with mugwort. She did not suffer from an oral allergy syndrome towards mugwort pollen cross allergens. Skin testing (prick and scratch testing) revealed a strong sensitisation against mugwort and estragon. Specific IgE antibodies against mugwort, sunflower, carrots, celery, fennel and anis were elevated in the peripheral blood. The observation of a severe mugwort allergy with life-threatening complications in a florist underscores the high allergenic potential of Artemisia vulgaris and documents for the first time the occupational significance of this allergy.

    A common radionuclide therapy carried out by nuclear medicine departments is the administration of 131 I for thyroid ablation and for hyperthyroid treatment. The administration of 140 a 600 MBq for hyperthyroid treatment and 3700 a 7400 MBq for carcinoma diseases is made after surgery to ablate thyroid tissues and metastasis. The revision of radiological protection was done on the occupational exposure of workers, members of the public and relatives of patients treated with 131 I. This paper presents the results of area and individual dosimetry to external exposure, surface activity and air concentration of 131 I carried out during the practice in the nuclear medicine department. An area survey in the isolation room allowed to determine exposure rate from surface activity and air concentration of 131 I. The patient clothes activity was determined as well as the activity excreted in urine and sweat. On the basis of this analysis, can be concluded that the annual effective dose for workers due to external and internal exposure, considering 40 iodine practice per year, reach values from 4 up to 30 mSv per year. The patients with cancer therapy treatment must be hospitalized during the first 48 hrs after iodine administration, in an isolated room taking into account the radioprotection of the staff, others patients and public during the isolation. The patients with hyperthyroid treatment do not need hospitalization but they must to follow the instructions given by the physician, which will take into account socioeconomic conditions. (author)

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

    The aim was to explore experiences of daily occupations among the oldest old. Ten 99-year-old persons were interviewed in their living environment about an ordinary day. The interviews were analysed according to the phenomenographic approach. The result showed that participants regarded themselves as competent and that they felt proud because they were involved in daily occupations. Being challenged was experienced as a way of performing difficult tasks, thus being confirmed as a capable person who performs and learns new things. The participants' occupational patterns preserve occupational ability and continuity in life in that they have a rhythm and allow the individuals to predict and handle interruptions. Participants experienced being incapable and being restricted as a result of personal, environmental, and social hindrances. The participants adapted to and reshaped their sense of self, which has been disrupted due to the discrepancy between self, the person's ability, and the real world "outside". Experience of daily occupation is unique, supports the sense of self, builds identities, and describes engagement and creative processes. Individual experience must be recognized as it can mean the difference between success and failure in maintaining meaningful daily occupation.

    Returning to work after maternity leave can be a challenging, anxious and fraught experience for women, and has been portrayed in the literature as a generally negative experience. Interestingly, although occupational therapists were predominantly women, no research was found focussing on their experiences of returning to work after maternity leave. The aim of this research was to gain an insight into occupational therapists' experiences of returning to work following maternity leave. Principles of interpretive phenomenological analysis were used to explore the individual experiences of six Australian occupational therapists returning to work after a period of maternity leave. Individual semi-structured interviews lasting up to 90 minutes were conducted. Interviews were audio-recorded, transcribed and then analysed. Two major themes emerged from the analysis of interviews: compromise and feeling valued. The experience of returning to work was a process of compromise in which women found strategies to cope with their changing roles and demands, to find a balance between home and work life. The women wanted to feel valued by their managers and co-workers, as this enabled them to feel comfortable and confident with some of the compromises they made. Occupational therapists returning to work after maternity leave will make compromises so that they can balance their home and work life. Occupational therapists value managers and co-workers who understand the compromises women make when returning to work following maternity leave and who create a supportive workplace that acknowledges and values their contribution. © 2013 Occupational Therapy Australia.

  10. Participatory citizenship: Critical perspectives on client-centred occupational therapy.

    Science.gov (United States)

    Fransen, Hetty; Pollard, Nick; Kantartzis, Sarah; Viana-Moldes, Inés

    2015-07-01

    This article aims to discuss client-centred practice, the current dominant approach within occupational therapy, in relation to participatory citizenship. Occupational therapists work within structures and policies that set boundaries on their engagement with clients, while working with complex, multidimensional social realities. The authors present a critical discussion shaped by their research, including a survey, discussions at workshops at international conferences, and critical engagement with the literature on occupational therapy, occupation, and citizenship. A focus on citizenship suggests reframing professional development based on the participation in public life of people as citizens of their society. While occupational therapists often refer to clients in the context of communities, groups, families, and wider society, the term client-centred practice typically represents a particular view of the individual and may sometimes be too limited in application for a more systemic and societal approach. The authors question the individual focus which has, until recently, been typical of client-centred occupational therapy. Placing citizenship at the core of intervention is a transformative process that assumes all people are citizens and conceives of health as a collective issue, influencing the way we educate, do research, and practise.

    Occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. Recently, staff network of different government universities of Thailand have called higher education commission, and Ministry of Education, Thailand to resolve the issue of government education policy (e.g. wage inequity, poor welfare, law, and job & environment condition) that leads to their job insecurity, physical and mental health problems from occupational stress. The aim of this study was to investigate a causal relationship of occupational stress among the academic university employees. This cross sectional research was conducted in 2014 among 2,000 academic university employees at Thai government universities using stratified random sampling. Independent variables were wage, family support, periods of duty, and job & environmental condition. Dependent variable was stress. Job & environmental condition, as social and environmental factor, and periods of duty as individual factor had direct effect to stress (Pstress (P stress among academic university employees at moderate level.

  13. The role of occupational attributes in gender earnings inequality, 1970-2010.

    Science.gov (United States)

    Mandel, Hadas

    2016-01-01

    Grounded in the research on the important role of social structures in forming gender inequalities, this study examines the effect of occupational attributes on the gender earnings gap over four decades. Using the IPUMS-USA from 1970 to 2010, the paper shows that occupational attributes cannot be reduced to the aggregate attributes of their individual incumbents. Rather, the effect of occupations on the gender earnings gap goes far beyond both the distributive role of occupational segregation and the effect of individual wage-related characteristics. Furthermore, occupations not only explain a significant portion of net gender pay gaps, but have also contributed to the narrowing of the gaps over the past several decades, as occupational attributes that favor women's pay have become more dominant over time.

    Foster, Erin R.; Bedekar, Mayuri

    2014-01-01

    We describe the results of a systematic review of the literature on occupational therapy–related interventions for people with Parkinson’s disease (PD). Three broad categories of intervention emerged: (1) exercise or physical activity; (2) environmental cues, stimuli, and objects; and (3) self-management and cognitive–behavioral strategies. Moderate to strong evidence exists for task-specific benefits of targeted physical activity training on motor performance, postural stability, and balance. Low to moderate evidence indicates that more complex, multimodal activity training supports improvement in functional movement activities. The evidence is moderate that the use of external supports during functional mobility or other movement activities has positive effects on motor control. In addition, moderate evidence is available that individualized interventions focused on promoting participant wellness initiatives and personal control by means of cognitive–behavioral strategies can improve targeted areas of quality of life. The implications for practice, education, and research are discussed. PMID:24367954

  18. Occupational exposure trend and the radiological protection optimization criteria in Spanish nuclear power plants in operation: present and future

    International Nuclear Information System (INIS)

    O'Donnell, P.

    1992-01-01

    Occupational collective dose per reactor evolution in the operating nuclear power plants in Spain has shown in the last years a tendency to stability, within a range of values similar to the average of the OECD countries. On the other hand, the last ICRP's recommendations will support a further effort for utilities and external contractors in order to adapt to the new individual dose limits. The lecturer considers that Spain must not accommodate to the present situation and should continue developing the ALARA criteria in its nuclear power plants. In this presentation the main indicators to assess the present development level of this criteria are reviewed and the basis to improve the effectiveness of the practical application of it is proposed.

    2006-01-01

    As stated in Art.III.A.6 of its Statute, the International Atomic Energy Agency (commonly referred to as the Agency) is authorized to establish or adopt, in consultation and, where appropriate, in collaboration with the competent organs of the United Nations and with the specialized agencies concerned, standards of safety for protection of health and minimization of danger to life and property (including such standards for labour conditions), and to provide for the application of these standards to its own operation as well as to the operations making use of materials, services, equipment, facilities, and information made available by the Agency or at its request or under its control or supervision. The Agency s Occupational Radiation Protection Programme aims at harmonizing infrastructures for the control of radiation exposure of workers and for optimizing radiation protection in situation s of exposures due to external radiation and intakes of radionuclides from both artificial and natural sources of radiation. Under its regular and technical cooperation programmes, the Agency has been assigning high priority to both the establishment of safety standards for labour conditions and for the application of these standards through, Interalia, direct assistance under its technical cooperation (TC) programme, the rendering of services, the promotion of education and training, the fostering of information exchange and the coordination of research and development. The purpose of this paper is to present the current status and future IAEA activities in support of occupational radiation protection. (authors)

    Lukács, J; Schliemann, S; Elsner, P

    2015-03-01

    Scabies is an infectious skin disease caused by the human itch mite (Sarcoptes scabiei var. hominis). It is mainly transmitted by direct skin-to-skin contact. The spread of scabies can cause major difficulties in healthcare institutions, particularly in residential homes for the elderly. The disease is characterized by intense nocturnal itching, erythematous papules arranged in a linear order, and scratching resulting in excoriations. The diagnosis is confirmed by identification of the mite or by finding one or more mite tunnels in the skin. An individually occurring case does not need to be reported. If two or more cases occur in the same institution, the company physician and the appropriate public health department are to be informed in Germany. In case of a suspected scabies infection in medical personnel due to exposure in their work setting, medical notification to the statutory occupational accidents' insurance (Nr. 3101) is to be issued in accordance with § 202, Volume VII of the German Social Code. First line treatment is topical therapy with 5 % permethrin. If scabies control is required in an institution, systemic treatment with ivermectin may be considered. In the case of a scabies outbreak, all patients, contact persons, and staff must be treated simultaneously.

    2017-03-01

    Objectives The standard approach to the assessment of occupational exposures is through the manual collection and coding of job histories. This method is time-consuming and costly and makes it potentially unfeasible to perform high quality analyses on occupational exposures in large population-based studies. Our aim was to develop a novel, efficient web-based tool to collect and code lifetime job histories in the UK Biobank, a population-based cohort of over 500 000 participants. Methods We developed OSCAR (occupations self-coding automatic recording) based on the hierarchical structure of the UK Standard Occupational Classification (SOC) 2000, which allows individuals to collect and automatically code their lifetime job histories via a simple decision-tree model. Participants were asked to find each of their jobs by selecting appropriate job categories until they identified their job title, which was linked to a hidden 4-digit SOC code. For each occupation a job title in free text was also collected to estimate Cohen's kappa (κ) inter-rater agreement between SOC codes assigned by OSCAR and an expert manual coder. Results OSCAR was administered to 324 653 UK Biobank participants with an existing email address between June and September 2015. Complete 4-digit SOC-coded lifetime job histories were collected for 108 784 participants (response rate: 34%). Agreement between the 4-digit SOC codes assigned by OSCAR and the manual coder for a random sample of 400 job titles was moderately good [κ=0.45, 95% confidence interval (95% CI) 0.42-0.49], and improved when broader job categories were considered (κ=0.64, 95% CI 0.61-0.69 at a 1-digit SOC-code level). Conclusions OSCAR is a novel, efficient, and reasonably reliable web-based tool for collecting and automatically coding lifetime job histories in large population-based studies. Further application in other research projects for external validation purposes is warranted.

    2013-01-01

    We sought to identify and describe the number, topics, and publishing trends of systematic reviews relevant to occupational therapy indexed in the OTseeker database. We performed a cross-sectional survey of the systematic reviews contained in OTseeker in December 2011. Of the 1,940 systematic reviews indexed in OTseeker, only 53 (2.7%) were published in occupational therapy journals. The most common diagnostic categories were stroke (n = 195, 10.1%) and affective disorders (n = 204, 10.5%). The most common intervention categories were consumer education (n = 644, 33.2%) and psychosocial techniques (n = 571, 29.4%). Only 390 (20.1%) of the 1,940 systematic reviews specifically involved occupational therapy. Occupational therapists need to search broadly to locate relevant systematic reviews or, alternatively, to use databases such as OTseeker. Clarity about the involvement of occupational therapy in reports of future research will improve the ability to identify occupational therapy research for all stakeholders. Finally, occupational therapy practitioners need to read systematic reviews critically to determine whether review conclusions are justified.

    Barnthouse, L.W.; Cada, G.F.; Cheng, M.-D.; Easterly, C.E.; Kroodsma, R.L.; Lee, R.; Shriner, D.S.; Tolbert, V.R.; Turner, R.S.

    1998-01-01

    This report describes methods for estimating the external costs (and possibly benefits) to human health and the environment that result from natural gas fuel cycles. Although the concept of externalities is far from simple or precise, it generally refers to effects on individuals' well being, that result from a production or market activity in which the individuals do not participate, or are not fully compensated. In the past two years, the methodological approach that this report describes has quickly become a worldwide standard for estimating externalities of fuel cycles. The approach is generally applicable to any fuel cycle in which a resource, such as coal, hydro, or biomass, is used to generate electric power. This particular report focuses on the production activities, pollution, and impacts when natural gas is used to generate electric power. In the 1990s, natural gas technologies have become, in many countries, the least expensive to build and operate. The scope of this report is on how to estimate the value of externalities--where value is defined as individuals' willingness to pay for beneficial effects, or to avoid undesirable ones. This report is about the methodologies to estimate these externalities, not about how to internalize them through regulations or other public policies. Notwithstanding this limit in scope, consideration of externalities can not be done without considering regulatory, insurance, and other considerations because these institutional factors affect whether costs (and benefits) are in fact external, or whether they are already somehow internalized within the electric power market. Although this report considers such factors to some extent, much analysis yet remains to assess the extent to which estimated costs are indeed external. This report is one of a series of reports on estimating the externalities of fuel cycles. The other reports are on the coal, oil, biomass, hydro, and nuclear fuel cycles, and on general

    1992-01-01

    Ergonomics is often defined simply as the study of work. Related or synonymous terms include human factors, human engineering, engineering psychology, and others. Occupational ergonomics is a term that has been proposed to describe the study of the working environment, including the physical consequences resulting from having an improperly designed workplace. The routine space working environment presents some problems not found in the typical Earthbound workplace. These include radiation, intravehicular contamination/pollution, temperature extremes, impact with other objects, limited psychosocial relationships, sensory deprivation, and reduced gravity. These are important workplace considerations, and may affect astronauts either directly at work or at some point during their life as a result of their work under these conditions. Some of the major issues associated with each of these hazards are presented.

    Occupational therapy is a global profession represented by the World Federation of Occupational Therapists (WFOT). International research priorities are needed for strategic guidance on global occupational therapy practice. The objective of this study was to develop international research priorities to reflect global occupational therapy practice. A Delphi study using three rounds of electronic surveys, distributed to WFOT member organizations and WFOT accredited universities, was conducted. Data were analyzed after each round, and priorities were presented for rating and ranking in order of importance. Forty-six (53%) out of 87 WFOT member countries participated in the Delphi process. Eight research priorities were confirmed by the final electronic survey round. Differences were observed in rankings given by member organizations and university respondents. Despite attrition at Round 3, the final research priorities will help to focus research efforts in occupational therapy globally. Follow-up research is needed to determine how the research priorities are being adopted internationally.

    2016-01-01

    Full Text Available Occupational behaviour is always an environmental behaviour because the occupation is the dialogue between human beings and their environment. Culture is key dimension in our profession. This article is based on previous research and a new review of the scientific literature on the various meanings associated with culture. In the contemporary context the globalization involves the imposition of the American way of life on a planetary scale. In front of ethnocentrism and racism a diatopical hermeneutics is proposed. A cosmopolitan citizenship can be constructed supporting diversity. The article concludes by reflecting on strategies that can be implemented from occupational therapy to develop a culturally safe occupational therapy. An archaeology of meaning must be developed in front of the Americanization. Occupational therapy needs to develop a powerful political activism in order to build an inclusive society based on human rights and sustainability. Culture and diversity are key elements in this process.

  15. Guidance for External Events Analysis

    International Nuclear Information System (INIS)

    This Guidance for External Events Analysis was developed under a contract with the Nordic PSA Group, and aims at creating a common framework for analysis of external events as part of a nuclear power plant Probabilistic Safety Assessment. Thus, the purpose of this Guidance is to constitute a common methodological guidance for the analysis of external events at Nordic nuclear power plants. This will make it possible for the utilities to perform these analyses in a cost-efficient way, assuring simultaneously the quality of the analyses. The Guidance is meant to clarify the scope of the analysis of external events, to provide guidance for the performance of the analysis, and to help in defining, subcontracting and reviewing the work. The analysis procedure includes four phases, addressing project planning, identification of external events, screening of events, and probabilistic analysis. The aim is first to do as complete an identification of potential single and combined external events as possible. Thereafter, as many external events as possible are screened out as early as possible. The screening capability is increased during the project, using the continuously acquired information on the events and on their effects on the plant

    Full Text Available Stress is an important problem in the majority of countries. Apart from the fact that it is responsible for numerous diseases, it also causes much suffering. Stress appears as an adaptation reaction of our body to those external factors that we perceive as being agressive and which frequently lead us to an alarm state, felt both psychically (tension, fear, anxiety, and physically (increase of the adrenaline secretion, intensity of heartbeats, sweating. It isn’t actually a disease, but it can lead to sickness in time. This is why it is good to know what stresses us and how we can escape stress.

  1. Assessing hypotheses about nesting site occupancy dynamics

    Science.gov (United States)

    Bled, Florent; Royle, J. Andrew; Cam, Emmanuelle

    2011-01-01

    Hypotheses about habitat selection developed in the evolutionary ecology framework assume that individuals, under some conditions, select breeding habitat based on expected fitness in different habitat. The relationship between habitat quality and fitness may be reflected by breeding success of individuals, which may in turn be used to assess habitat quality. Habitat quality may also be assessed via local density: if high-quality sites are preferentially used, high density may reflect high-quality habitat. Here we assessed whether site occupancy dynamics vary with site surrogates for habitat quality. We modeled nest site use probability in a seabird subcolony (the Black-legged Kittiwake, Rissa tridactyla) over a 20-year period. We estimated site persistence (an occupied site remains occupied from time t to t + 1) and colonization through two subprocesses: first colonization (site creation at the timescale of the study) and recolonization (a site is colonized again after being deserted). Our model explicitly incorporated site-specific and neighboring breeding success and conspecific density in the neighborhood. Our results provided evidence that reproductively "successful'' sites have a higher persistence probability than "unsuccessful'' ones. Analyses of site fidelity in marked birds and of survival probability showed that high site persistence predominantly reflects site fidelity, not immediate colonization by new owners after emigration or death of previous owners. There is a negative quadratic relationship between local density and persistence probability. First colonization probability decreases with density, whereas recolonization probability is constant. This highlights the importance of distinguishing initial colonization and recolonization to understand site occupancy. All dynamics varied positively with neighboring breeding success. We found evidence of a positive interaction between site-specific and neighboring breeding success. We addressed local

Specifically, incorporating many of the quantitative scientific methods and analyses employed in movement science can help accelerate the development of rehabilitation-relevant research in occupational therapy (OT) and occupational science (OS). Reciprocally, OT and OS, which focus on the performance of everyday activities (occupations) to promote health and well-being, provide theoretical frameworks to guide research on the performance of actions in the context of social, psychological, and environmental factors. Given both fields' mutual interest in the study of movement as it relates to health and disease, the authors posit that combining OS and OT theories and principles with the theories and methods in movement science may lead to new, impactful, and clinically relevant knowledge. The first step is to ensure that individuals with OS or OT backgrounds are academically prepared to pursue advanced study in movement science. In this article, the authors propose 2 strategies to address this need.

    Two-sided matchings are an important theoretical tool used to model markets and social interactions. In many real-life problems the utility of an agent is influenced not only by their own choices, but also by the choices that other agents make. Such an influence is called an externality. Whereas...... fully expressive representations of externalities in matchings require exponential space, in this paper we propose a compact model of externalities, in which the influence of a match on each agent is computed additively. Under this framework, we analyze many-to-many matchings and one-to-one matchings...

    The article discusses the external costs and benefits of hydropower that are not internalised in normal book-keeping. Several negative and positive effects are discussed. The results of a study that addressed the difficult task of quantifying these external effects are presented. An assessment of the results gained shows that difficulties are to be met regarding system limits, methods of expressing the effects in monetary terms and ethical factors. The report also examines the consideration of external effects as a correction factor for falsified market prices for electricity

  7. Consumer or Citizen: A Study About Externalities in Energy Consumption

    2016-07-01

    Full Text Available The main purpose of this article is to discuss how negative externalities generated by consumption can have impact on the same individual in his/her role as a citizen and consumer. Therefore, in order to highlight this relation,a generation, distribution and consumption of electricity systemwas presented. Asto  methodological procedures, anexploratory and deductive typehas been adopted so as to approach the study, ie, we have started from general concepts on consumer behaviour and externalities, in order to build a relationship between the two concepts so as to explain citizen-conscious consumption-citizen. Regarding the analysis, a qualitative approach has been used for appreciation of content analysis. The main results of this research that can be highlighted are that both the negative externalities generated in production and distribution and the negative consumption externalities are absorbed by individuals in their roles as consumers or citizens. In this case, externalities are assimilated in the power supply bill or the government bill. So anyway the individual will pay,either as a consumer or as a citizen. So, to understand that externalities generated in consumer processes will be internalized and directed to oneself,, one can build a sense of "consumer-citizen".

  8. Leading multiple teams: average and relative external leadership influences on team empowerment and effectiveness.

    2014-03-01

    External leaders continue to be an important source of influence even when teams are empowered, but it is not always clear how they do so. Extending research on structurally empowered teams, we recognize that teams' external leaders are often responsible for multiple teams. We adopt a multilevel approach to model external leader influences at both the team level and the external leader level of analysis. In doing so, we distinguish the influence of general external leader behaviors (i.e., average external leadership) from those that are directed differently toward the teams that they lead (i.e., relative external leadership). Analysis of data collected from 451 individuals, in 101 teams, reporting to 25 external leaders, revealed that both relative and average external leadership related positively to team empowerment. In turn, team empowerment related positively to team performance and member job satisfaction. However, while the indirect effects were all positive, we found that relative external leadership was not directly related to team performance, and average external leadership evidenced a significant negative direct influence. Additionally, relative external leadership exhibited a significant direct positive influence on member job satisfaction as anticipated, whereas average external leadership did not. These findings attest to the value in distinguishing external leaders' behaviors that are exhibited consistently versus differentially across empowered teams. Implications and future directions for the study and management of external leaders overseeing multiple teams are discussed.

    1985-01-01

    With the increasing industrialisation of the world has come an increase in exposure to hazardous chemicals. Their effect on the body depends upon the concentration of the element in the work environment; its chemical form; the possible different routes of intake; and the individual's biological response to the chemical. Nuclear techniques of analysis such as neutron activation analysis (NAA) and proton induced X-ray emission analysis (PIXE), have played an important role in understanding the effects hazardous chemicals can have on occupationally exposed workers. In this review, examples of their application, mainly in monitoring exposure to heavy metals is discussed

  12. Ethics in biomonitoring for occupational health.

    Science.gov (United States)

    Manno, M; Sito, F; Licciardi, L

    2014-12-01

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

    Studies on occupational skin diseases in workers of the automotive industry are few. To investigate the prevalence of occupational skin diseases in workers of the automotive industry. Between September and December 2011, a total of 405 workers from the automotive repair industry in Diyarbakır were interviewed. They were active workers in the repair industry who had been employed for at least six months. Business owners, sellers of spare parts and accounting officers were not included. The employees were examined at their workplaces and the working conditions were observed. Detailed dermatological examination was performed. The mean age of the 405 workers who participated in the study was 27.7 ± 10.3. The mean working time of employees was 13.3 ± 10.4 years. All of the employees were male. Dermatological diseases were not detected in 144 out of 405 workers (35.6%) and at least one condition was diagnosed in 261 (64.4%). The most frequent diagnosis was callus, hyperkeratosis, clavus (27.7%), followed by nail changes (16.8%) and superficial mycoses (12.1%). Contact dermatitis was seen at a rate of 5.9%. Traumatic lesions such as hyperkeratotic lesions and nail changes were found most frequently. Traumatic lesions were common among individuals who did not use gloves. Most nail changes were localized leuconychia, a finding not reported in the studies on automotive industry workers. In accordance with the literature, irritant contact dermatitis was observed in patients with a history of atopy and who had been working for a long time. Occupational skin diseases comprise an important field in dermatology, deserving much attention. Further studies on occupational dermatology are necessary.

    The growing interest for developing economic instruments for efficient environmental policies has opened up a large area of multi-disciplinary research. ExternE is an example of this research, combining disciplines such as engineering, ecology, immunology and economics expertise to create new knowledge about how environmental pressures from energy production affect our nature and society. The ExternE Project aims to identify and, as far as possible quantify the externalities of energy production in Europe. The Stockholm Environment Institute has carried out a preliminary aggregation: -Coal Fuel Cycle: centred around Vaesteraas Kraftvaermeverk, Vaesteraas. This is the largest co-generation plant in Sweden, with four blocks and a maximum co-generation output of 520 MW electricity and 950 MW heat. The analysis is carried out on boiler B4. -Biomass Fuel Cycle: centred around Haendeloeverket, Norrkoeping. This plant predominately burns forestry residues, but a variety of fuels are combusted. Haendeloeverket has an installed capacity of 100 MW electricity and 375 MW heat, in a total of three boilers and two back-pressure turbines. The analysis is carried out on boiler P13. -Hydro Fuel Cycle: Klippens Kraftstation, Storuman. Built in 1990-1994, it is the youngest hydro power station in Sweden. It has been designed and built with significant efforts to account for and protect environmental values. Installed capacity is 28 MW. The environmental impact assessment from the construction of this plant is carried out, but the evaluation is still not finalized. The preliminary aggregation aimed to test whether ExternE results could be used to make estimates for the entire Swedish electricity production system. Hence, national results as well as results from other partner countries in ExternE has been applied

    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

    2010-11-01

    To test aspects of a theory of the role of personality and gender on the development of vocational interests and their subsequent effects on adult occupational choices, the authors of this study examined associations among childhood personality traits, gender, and occupational environments more than 40 years later. Participants (N = 587) were assessed on the Big Five by their teachers when the participants were between 6 and 12 years old. In middle-age (late 40s), the participants reported their occupation. Holland's (1997) RIASEC vocational types (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) were used to characterize the job environments of reported occupations. Childhood Openness/Intellect and Conscientiousness, but no other Big Five traits, were associated with occupational environments. For the most strongly sex-typed work environments, associations with Openness/Intellect were moderated by gender. These findings suggest that the roots of the strongest gender-stereotyping effects in occupations may be found not only in the social factors associated with gender but also in the individual differences of children related to Openness/Intellect.

  8. Unilateral vestibular loss impairs external space representation.

    Directory of Open Access Journals (Sweden)

    Liliane Borel

    Full Text Available The vestibular system is responsible for a wide range of postural and oculomotor functions and maintains an internal, updated representation of the position and movement of the head in space. In this study, we assessed whether unilateral vestibular loss affects external space representation. Patients with Menière's disease and healthy participants were instructed to point to memorized targets in near (peripersonal and far (extrapersonal spaces in the absence or presence of a visual background. These individuals were also required to estimate their body pointing direction. Menière's disease patients were tested before unilateral vestibular neurotomy and during the recovery period (one week and one month after the operation, and healthy participants were tested at similar times. Unilateral vestibular loss impaired the representation of both the external space and the body pointing direction: in the dark, the configuration of perceived targets was shifted toward the lesioned side and compressed toward the contralesioned hemifield, with higher pointing error in the near space. Performance varied according to the time elapsed after neurotomy: deficits were stronger during the early stages, while gradual compensation occurred subsequently. These findings provide the first demonstration of the critical role of vestibular signals in the representation of external space and of body pointing direction in the early stages after unilateral vestibular loss.

    2005-01-01

    Many wildlife studies seek to understand changes or differences in the proportion of sites occupied by a species of interest. These studies are hampered by imperfect detection of these species, which can result in some sites appearing to be unoccupied that are actually occupied. Occupancy models solve this problem and produce unbiased estimates of occupancy and related parameters. Required data (detection/non-detection information) are relatively simple and inexpensive to collect. Software is available free of charge to aid investigators in occupancy estimation.

    2011-01-01

    The American Occupational Therapy Association (AOTA) has challenged occupational therapy practitioners to advance the profession so that we may become more "powerful" and "widely recognized" by the year 2017 (AOTA, 2007a). To fully achieve this vision, this article argues that the profession should encourage occupational therapy entrepreneurship. As Herz, Bondoc, Richmond, Richman, and Kroll (2005, p.2) stated, "Entrepreneurship may provide us with the means to achieve the outcomes we need to succeed in the current health care environment." This article also argues the urgency of seizing the many opportunities that entrepreneurship offers and recommends specific actions to be taken by AOTA and by therapists.
