Sick at work: prevalence and determinants among healthcare workers, western Ethiopia: an institution based cross-sectional study
ConclusionRelatively higher proportions of workers indicated sickness presenteeism as compared to other studies. Risk factors like educational status, personal financial problem, sickness absenteeism, lack of staff replacement, absence of occupational health services, and pressure from supervisors considerably increased the likely occurrence of employees ’ sick attendance. It is advisable for health care managers to hire adequate health care staffs, to implement basic occupational health services and to design strategies which reduce pressure from supervisors.

Marginal socio-economic effects of an employer ’s efforts to improve the work environment
ConclusionEnvironmental factors at the workplace are the important determinant factor for OLE, and the latter is where socio-economic impacts of the employer ’s efforts primarily manifest. (Source: Annals of Occupational and Environmental Medicine)

Does formaldehyde have a causal association with nasopharyngeal cancer and leukaemia?
ConclusionAdditional evidence is needed to confirm the relationship between formaldehyde exposure and nasopharyngeal cancer. All lymphohematopoietic malignancies, including leukemia, should be considered in cases with occupational formaldehyde exposure. (Source: Annals of Occupational and Environmental Medicine)

Recognition criteria for occupational cancers in relation to hepatitis B virus and hepatitis C virus in Korea
In conclusion, we recommend keeping the current specific criteria. However, if a worker is injured at work when using a sharp medical device, and HBV and HCV viral infections are confirmed through serologic tests; if the worker is diagnosed as having a chronic HBV or HCV infection, a subsequent HCC (or Non-Hodgkin ’s lymphoma following chronic HCV infection) can then be considered highly related to the worker’s occupation.

Silica exposure and work-relatedness evaluation for occupational cancer in Korea
AbstractCrystalline silica has been classified as a definite carcinogen (Group 1) causing lung cancer by the International Agency for Research on Cancer (IARC). In Korea, crystalline silica has been the most common causal agent for workers to apply to the Korea Workers ’ Compensation and Welfare Service (KWCWS). We used KWCWS data to evaluate workers’ crystalline silica exposure levels according to their occupations and industries, and reviewed research papers describing the dose-response relationship between cumulative exposure levels and lung cancer incidenc e. In addition, we reviewed lung cancer cases accepted by t...

Probability of causation for occupational cancer after exposure to ionizing radiation
ConclusionsPC is one of the most advanced tools for estimating the causation of occupational cancer. PC has been adjusted for baseline cancer incidence in Korean workers, and for uncertainties using a statistical method. Because the fundamental reason for under- or over-estimation is probably inaccurate dose reconstruction, a proper guideline is necessary. (Source: Annals of Occupational and Environmental Medicine)

Review of carcinogenicity of hexavalent chrome and proposal of revising approval standards for an occupational cancers in Korea
ConclusionsIt is suggested that the current recognition standard which is “Lung cancer or nasal and paranasal sinus cancer caused by exposure to chromium (VI) or compounds thereof (exposure for two years or longer), or nickel compounds” should be changed to “Lung cancer caused by exposure to chromium (VI) or compounds thereof, and lung cancer or nasal and paranasal sinus cancer caused by exposure to nickel compounds”.

Reticulocytosis in screen-printing workers exposed to 2-butoxyethanol and 2-ethoxyethanol
ConclusionsExposure to 2-butoxyethanol and 2-ethoxyethanol was significantly associated with reticulocytosis, necessitating the implementation of preventive measures for workers prone to occupational exposure to ethylene glycol ethers. (Source: Annals of Occupational and Environmental Medicine)

Factors increasing the risk for psychosocial stress among Korean adults living in rural areas: using generalized estimating equations and mixed models
ConclusionsShort sleep duration, no regular exercise, and long sedentary time in the white-collar group were identified as risk factors toward the PWI-SF high-risk group in the rural communities, and policy interventions are needed to address this issue.

Carbon disulfide exposure estimate and prevalence of chronic diseases after carbon disulfide poisoning-related occupational diseases
ConclusionsWe estimated the individual cumulative CS2 exposure based on interviews and foreign measurement documents, and work environment measurement data. Comparing the work environment measurement data from 1992, these values were similar to them. After identified as CS2 poisoning, there are subjects over 70  years of average age with disorders of the nervous system and sensory organs, hypertension, psychoneurotic disorder, cerebrovascular disease, diabetes, coronary artery disease, and arrhythmia. Because among ex-workers of the rayon manufacturing plant, only 633 survivors recognized as CS2 poisoning were studied, th...

Relationship between dietary factors and bisphenol a exposure: the second Korean National Environmental Health Survey (KoNEHS 2012 –2014)
ConclusionsBPA levels were high in female using bottled water and in male consuming frozen food, and therefore bottled water and frozen food need to be avoided to reduce BPA levels. (Source: Annals of Occupational and Environmental Medicine)

Relationship of activities outside work to sleep and depression/anxiety disorders in Korean workers: the 4th Korean working condition survey
ConclusionSome of activities outside work were related to sleep disorders and depression/anxiety disorders among Korean wage workers. Our results showed negative health effect of some kinds of activities outside work such as volunteering and self-devlopment compared to other studies that emphasized positive effect of those activities for health.

Association between supervisors ’ behavior and wage workers’ job stress in Korea: analysis of the fourth Korean working conditions survey
ConclusionSupervisors ’ behavior influenced job stress levels in workers. Therefore, it is necessary to increase education regarding the effects of supervisors’ behavior on job stress, which should initially be provided in private-sector organizations with up to 300 employees.

The relationship between spontaneous abortion and female workers in the semiconductor industry
ConclusionsWhen examining the pregnancies of female semiconductor workers that occurred prior to 2008, packaging process workers showed a significantly higher risk for spontaneous abortions than did clerical workers. The two semiconductor production periods in our study (prior to 2008 vs. after 2009) had different automated processes, chemical exposure levels, and working environments. Thus, the conditions prior to 2008 may have increased the risk for spontaneous abortions in packaging process workers in the semiconductor industry.
