1.Urbanization and workers' compensation in China from 1995 to 2012.
Biomedical and Environmental Sciences 2014;27(3):220-230
In order to determine the trend in the number of employees covered by workers' compensation (WC) and trends in the burdens and benefits of WC, and to discuss the possible factors that might influence those trends. A relevant national statistical data from 1995 to 2012 are collected and analyzed. In the results, we found that the proportion of employees covered by WC to total employees in urban areas increased from 13.7% in 1995 to 51.2% in 2012 and also exhibited a significant degree of polarization. In 2012, 27.3% of the peasant workers were covered by WC, which accounted for 37.8% of the total employees covered by WC. Factors found to impact the number of employees covered by WC and trends in the burdens and benefits of WC from 1995 to date in China included urbanization, represented by the migration of farm labor to urban areas, changes in industry mix, regional disparity, GDP movements, and changes to legislation on WC and occupational health and safety. It still has a long way to go to reduce work-related injuries and occupational diseases (ODs) to levels comparable with other industrialized countries.

The purpose of this study was to develop a disability rating scale according to job classification using the Korean Academy of Medical Society (KAMS) guidelines. All jobs were categorized based on their level of physical activity and professional skills. The KAMS guidelines were used for the impairment rating. We modified the California Schedule for rating permanent disabilities. The differences were plotted to compare between the impairment rate and the job-adjusted disability rate. The KAMS job-adjusted disability rates were then compared to the McBride and workers' compensation rates. A total of 1,206 occupations were classified into 44 groups. The occupational disability indexes were rated on a scale of 1 to 7. The differences in the McBride disability rates varied inconsistently from 0% to 35%, while the differences in the KAMS disability rates were between 0% and 18%. The KAMS disability rates were slightly higher than the McBride disability rates for the upper extremities, but were lower for the lower extremities and internal organs. This is the first Korean job-adjusted disability rating method. There are several limitations, but its impairment rating is more scientific and reflects the current Korean occupational environment.

Journal of Korean Medical Science 2013;28(11):1581-1586
This study examined the association between return-to-work and impairment type. Database of the Korea Workers' Compensation and Welfare Service was used to identify disabled persons; and return-to-work information was obtained from the Korea Employment Information Services database. The study participants were 79,328 persons who received Workers' compensation and who were confirmed as disabled during 2009-2011. Logistic regression was used to analyze the association between return-to-work and impairment type, adjusted by age, sex, impairment severity, pre-injury businesses size, and pre-injury occupational category. Compared to injuries of the upper limbs, the odds ratio of return-to-work was 0.63 (95% CI, 0.60-0.65) for injuries involving the lower limbs, 0.62 (95% CI, 0.59-0.66) for the spine, 0.75 (95% CI, 0.66-0.86) for the eyes, 0.98 (95% CI, 0.77-1.25) for the oral cavity, 0.44 (95% CI, 0.37-0.53) for the ears, 1.02 (95% CI, 0.83-1.25) for the figure, 0.75 (95% CI, 0.72-0.79) for pain, and 0.36 (95% CI, 0.32-0.41) for neuropsychiatric impairment. These findings indicate that impairment type influences return-to-work rates.

Journal of Korean Medical Science 2014;29(11):1473-1481
An understanding of the characteristics of occupational lung cancer is important to establish policies that prevent carcinogen exposure and to compensate workers exposed to lung carcinogens. This study analyzed the characteristics of occupational lung cancers in workers who were compensated under the Industrial Accident Compensation Insurance Law between 1994 and 2011. A total of 179 occupational lung cancers were compensated. The main carcinogenic exposure was asbestos, followed by crystalline silica and hexavalent chromium. The mean exposure duration and latency were 19.8 and 23.2 yr. The most common industry was manufacturing, followed by construction and transportation. The most common occupation was maintenance and repair, followed by foundry work, welding, painting, and spinning or weaving. Although asbestos was predominant carcinogen, the proportion of these cases was relatively low compared to other developed countries. Proper surveillance system is needed to monitor occupational lung cancer and improve prevention measures.

We aimed to examine whether there is a correlation between the health recovery of industrial accident victims and their perceived socioeconomic status. Data were obtained from the first Panel Study of Worker's Compensation Insurance, which included 2,000 participants. We performed multivariate regression analysis and determined the odds ratios for participants with a subjectively lower socioeconomic status and for those with a subjectively lower middle socioeconomic status using 95% confidence intervals. An additional multivariate regression analysis yielded the odds ratios for participants with a subjectively lower socioeconomic status and those with a subjectively upper middle socioeconomic class using 95% confidence intervals. Of all participants, 299 reported a full recovery, whereas 1,701 did not. We examined the odds ratio (95% confidence intervals) for participants' health recovery according to their subjective socioeconomic status while controlling for sex, age, education, tobacco use, alcohol use, subjective state of health prior to the accident, chronic disease, employment duration, recovery period, accident type, disability status, disability rating, and economic participation. The odds of recovery in participants with a subjectively lower middle socioeconomic status were 1.707 times greater (1.264-2.305) than that of those with a subjectively lower socioeconomic status. Similarly, the odds of recovery in participants with a subjectively upper middle socioeconomic status were 3.124 times greater (1.795-5.438) than that of those with a subjectively lower socioeconomic status. Our findings indicate that participants' perceived socioeconomic disparities extend to disparities in their health status. The reinforcement of welfare measures is greatly needed to temper these disparities.
