Background: Methyl alcohol poisoning in mobile phone-manufacturing factories during 2015-2016 was caused by methyl alcohol use for cleaning in computerized numerical control (CNC) processes. To determine whether there were health complications in other workers involved in similar processes, the Occupational Safety and Health Research Institute conducted a survey. Methods: We established a national active surveillance system by collaborating with the Ministry of Employment and Labor and National Health Insurance Service. Employment and national health insurance data were used. Overall, 12,048 employees of major domestic mobile phone companies and CNC process dispatch workers were surveyed from 2016 to 2017. We investigated methyl alcohol poisoning by using the national health insurance data. Questionnaires were used to investigate diseases due to methyl alcohol poisoning. Results: Overall, 24.9% of dispatched workers were employed in at least five companies, and 23.9% of dispatched workers had missing employment insurance history data. The prevalence of blindness including visual impairment, optic neuritis, visual disturbances, and alcohol toxicity in the study participants was higher than that reported in the national health insurance database (0.02%, 0.07%, 0.23%, and 0.03% versus 0.01%, 0.07%, 0.13%, and 0.01%, respectively, in 2015). Moreover, 430 suspicious workers were identified; 415 of these provided an address and phone number, of whom 48 responded (response rate, 11.6%). Among the 48 workers, 10 had diseases at the time of the survey, of whom 3 workers were believed to have diseases related to methyl alcohol exposure. Conclusion: This study revealed that active surveillance data can be used to assess health problems related to methyl alcohol poisoning in CNC processes and dispatch workers.

Aircraft ground services are essential to the aviation industry and aviation services, yet management systems and improvement measures for operations and safety have not been adequately addressed in the revision of the old aviation law. This study utilized structural equation modeling and the UTAUT model to analyze the perceived acceptance of smart safety technologies among ground handling service workers. The findings indicated that perceived ease of use had a more significant than perceived usefulness impact on the acceptance of smart safety technologies among ground handling service workers. In light of these findings, it is recommended that the aviation safety management authority establish a policy vision for the adoption of smart safety technologies and consider implementing measures such as the introduction of smart safety technology test beds to enhance safety management and work efficiency of aircraft ground handling services.

Purpose - This paper investigates whether one's occupation influences one's attitude toward people with HIV/AIDS and suggests ways to counter HIV-related stigma in different work settings. Two samples comprising workers in different environments and occupations with contrasting personalities were chosen. Thus, security guards (authoritarian types) and catering workers (social types) were included. Research design, data, and methodology - The sample comprised246 service staff from the Rhodes University Catering Division and the Hi-Tec Security company, both in Grahamstown, South Africa, a small Eastern Cape province town. All employees at these organizations during the survey were eligible to participate. Results -The security sample displays significantly higher personal stigma scores than the catering sample, according to the Visser personal stigma scale (mean scores of 4.01 and 1.37, respectively; t=10.30, df=244, p=0.00). Similar results were found using Visser subscales. Conclusions - This study shows that occupation is a strong predictor of HIV-related stigma in the workplace, suggesting that workplace settings, by attracting particular personalities and influencing workers, may shape attitudes towards those who are HIV positive.

Objectives : This study investigated the health care utilization patterns and length of stay (LOS) determinants of fracture patients with workers' compensation insurance (WCI) and national health insurance (NHI). Methods : The discharge summary data of 4,394 WCI fracture patients were compared to 28,874 NHI patients. Health care utilization characteristics were compared with a logistic regression analysis, and the LOS determinants were identified with linear regression analysis. Results : The average LOS of the WCI fracture patients was 2.4 times higher than that of the NHI patients. WCI patients used more small or medium sized hospitals, and were more frequently admitted through the emergency room. Females, older patients and patients admitted through emergency room had a significant positive impact on LOS. Conclusions : Healthcare utilization by the WCI fracture patients may include medically unnecessary hospital stays. Therefore, policy makers need to respond appropriately to the inefficient use of health resources by WCI patients.

Objectives: The purpose of this study was to determine the effectiveness of hand acupressure in relieving shoulder pain among male manufacturing workers. Methods: A nonequivalent control group was employed using a nonsynchronized design. Data were collected from two manufacturing plants located in metropolitan area U. The data were analyzed with a ${\chi}^2$-test and an independent t-test to perform a homogeneity test, and with repeated ANOVA measures to perform an hypothesis test using the SPSS 21.0 program. Results: Hypothesis 1 that "the experimental group provided with hand moxibustion would score lower for low shoulder pain than the control group" was supported (F=306.05, p<.001). Hypothesis 2, that "the experimental group provided with hand moxibustion would have a wider range of motion than the control group" was also supported with increased flexion(F=7.73, p<.001), extension(F=7.89, p=.001), abduction(F=21.23, p<.001), and horizontal abduction(F=20.89, p=.028). Hypothesis 3, that "the experimental group provided with hand moxibustion would score lower for quality of sleep than the control group" was not supported (F=56.10, p=.091). Conclusions: Hand moxibustion is effective in relieving shoulder pain for male manufacturing workers, in relieving low shoulder pain and increasing the range of motion.
