Objectives: The lung cancer mortality in Korea has increased remarkably during the last 20 years, and has been the first leading cause of cancer-related deaths since 2000. The aim of the current study was to examine the time trends of occupational lung cancer and carcinogens exposure during the period 2006-2009 in South Korea, by assessing the proportion of occupational burden. Methods: We defined occupational lung cancer for surveillance, and developed a reporting protocol and reporting website for the surveillance of occupational lung cancer. The study patients were chosen from 9 participating university hospitals in the following 7 areas: Seoul, Incheon, Wonju, Daejeon, Daegu, Busan, and Gwangju. Results: The combined proportion of definite and probable occupational lung cancer among all lung cancers investigated in this study was 10.0%, 8.6%, 10.7%, and 15.8% in the years 2006 to 2009, respectively, with an average of 11.7% over the four-year study period. The main carcinogens were asbestos, crystalline silica, radon, polyaromatic hydrocarbons (PAHs), diesel exhaust particles, chromium, and nickel. Conclusion: We estimated that about 11.7% of the incident lung cancer was preventable. This reveals the potential to considerably reduce lung cancer by intervention in occupational fields.

Abstract Background This study aimed to identify the difference of perception about the role of appointing health officers by comparing and analyzing the response of entrustment workplace (EW) and specialized health management institution (SI). This is considered an important aspect of an institutional assessment to improve the quality of health management services. Methods A survey questionnaire was mailed to 122 SIs and 319 EWs nationwide. The questionnaire survey was about the general characteristics of SIs and EWs and main occupations for each evaluation item. In total, 81 SIs (66.4%) and 30 EWs responded to the questionnaire. A logistic regression analysis was performed to compare the opinions of SI and EW. Results Based on the analysis, the items showing statistically significant differences were as follows. Doctors’ main tasks survey: “Guidance on their wearing personal protective equipment (PPE)” (OR: 4.58), “Guidance of improvement of work environment (WE)” (OR: 3.33), etc.; Nurses’ main tasks survey: “Guidance on their wearing PPE” (OR: 3.86), “Guidance for programs on health process in confined space (CS)” (OR: 0.36), “Guidance on the hearing conservation program (HCP)” (OR: 0.28), etc.; Industrial hygienist (IH)‘s main tasks survey: “Guidance of work through inspection (WTI)” (OR: 0.15), “Guidance on the improvement of WE” (OR: 0.32), “Management confirmation of substances used by process and Material Safety Data Sheet (MSDS)” (OR: 0.08), “Guidance on posting or keeping of MSDS and warning signs” (OR: 0.03), “Prevention of dust-induced medical problems” (OR: 0.28), “Guidance for programs of health process in CS” (OR: 0.39), etc. Conclusions It is necessary to educate the EWs to recognize the need for physicians to perform tasks, such as wearing a PPE, and instruction to improve WE. As for nurses’ tasks, such as education about the CS and the noise work, educating the nurses of the SI is regarded necessary as the demand of the EWs is considered. With respect to the unique tasks of IH, such as WE management and instructions for wearing PPE, among several other tasks of IH, training should be provided for improved IH recognition.

Abstract Background ‘Work related musculoskeletal disorders (WRMSDs)’ have been mostly reported in the manufacturing industry but recently the occurrence of industrial injuries has been constantly increasing in the service industry. This research is going to analyze the data about workers’ compensation for WRMSDs in five different service sectors and identify characteristics of occupations with the highest approved occupations. Methods According to the data released from the Korea Worker’s Compensation & Welfare Service, the overview of 12,730 cases of workers’ compensation for WRMSDs in five service sectors from 2004 to 2013 is going to be analyzed and the source data is going to be classified by the Korean Standard Classification of Occupations to select the top five occupations that have the highest number of approval. Results After selecting each five occupations from the service sector that have work related musculoskeletal disorders, the result showed that the occupation with the highest number of approval in the health and social care sector were the early childhood educators, cooks in the school canteens in education services sector, garbage collectors in the sanitation and similar services sector, deliverymen in wholesale and retail, consumer goods repair and building cleaners in general management businesses such as those in building maintenance. The major event observed in the top five occupations was the overexertion and reaction as a cause of WRMSDs. The day when the WRMSDs mostly occurred was on Monday and the most likely time was 10 am. The median days away from work and lost working days are 29–90 days and 0–50 days respectively. The difference in each occupation was observed in year of service, age, and gender. Conclusions 83.21% of the approved cases of workers’ compensation for WRMSDs occurred in the top 25 occupations in all of the five service sectors, which meant that the approval of workers’ compensation is concentrated in specific occupations. This research is going to suggest preventive measures for work related musculoskeletal disorders in the service industry and to help prioritize the preventive measures. Trial registration Not applicable.

The CAN (Controller Area Network) bus, which transmits and receives ECU control information in vehicle, has a critical risk of external intrusion because there is no standardized security system. Recently, the need for IDS (Intrusion Detection System) to detect external intrusion of CAN bus is increasing, and high accuracy and real-time processing for intrusion detection are required. In this paper, we propose Hybrid MR (Machine learning and Ruleset) -IDS based on machine learning and ruleset to improve IDS performance. For high accuracy and detection rate, feature engineering was conducted based on the characteristics of the CAN bus, and the generated features were used in detection step. The proposed Hybrid MR-IDS can cope to various attack patterns that have not been learned in previous, as well as the learned attack patterns by using both advantages of rule set and machine learning. In addition, by collecting CAN data from an actual vehicle in driving and stop state, five attack scenarios including physical effects during all driving cycle are generated. Finally, the Hybrid MR-IDS proposed in this paper shows an average of 99% performance based on F1-score.

We studied the association of occupational and environmental agents with chronic fibrosing idiopathic interstitial pneumonia (IIP) in South Korea.We recruited 92 patients with chronic fibrosing IIP and 92 matched controls who had normal chest radiograph findings by age and gender. We used a structured exposure questionnaire to evaluate potential occupational and environmental risk factors for chronic fibrosing IIP, with adjustments for age, smoking, and clinical risk factors.We used conditional logistic regression models to analyze associations with chronic fibrosing IIP adjusted for age, smoking and clinical risk factors. Exposure to stone, sand, or silica significantly increased the risk of chronic fibrosing IIP (odds ratio = 5.01; 95% confidence interval, 1.07-24.21) CONCLUSIONS:: Our findings indicate that exposure to stone, sand, and silica might constitute a risk factor for developing chronic fibrosing IIP in the Korean population.

To elucidate the correlates of self-rated fatigue in Korean employees.The data for 10,176 (men, 7984; women, 2192; mean age, 34.2; SD: 8.8) employees recruited from a nation-wide sample were examined. A structured questionnaire was used to measure the participants' fatigue, sociodemographics (sex, age, education, and marital status), job-related characteristics (work duration, grade at work, work hours, shiftwork, employment type, and magnitude of workplace), and health-related habits (smoking, drinking, coffee intake, and exercise). Two types of measurement for fatigue were used to evaluate the magnitude of fatigue: self-rated question and a standardized measurement tool (Multidimensional Fatigue Scale: MFS).According to the self-rated fatigue, 32% of employees reported that they felt fatigue for the past two weeks, and 9.6% of males and 8.7% of females had experienced excessive fatigue (6 months or more). Hierarchical multiple regression analysis showed that fatigue measured by MFS was more common in women, younger, college or more graduated, single, and employees who do not regularly exercise. Fatigue was also associated with long work hours, and the size of the workplace (1000 employees).These results suggest that fatigue has been considered as a common complaint, and that it is affected by job-related factors like work hours and the workplace size as well as sociodemographics or health-related behaviors. Further research is needed to clarify the effects of fatigue on adverse health,outcomes, work performance, work disability, sick absence and medical utilization, and to examine the relationship of job characteristics (e.g.: work demand, decision latitude) to fatigue.

To estimate the magnitude of psychosocial distress and examine eligible factors associated with the development of psychosocial distress in Korean employees, using a nationwide sample.A total of 6977 workers were recruited from 245 companies. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, social support at work, personality traits (locus of control, type A behavior pattern), self-esteem, and psychosocial distress.The results showed that 23% of workers were categorized as high stress, 73% as moderate, and 5% as normal. Hierarchical multiple regression analysis showed that psychosocial distress was more common in younger workers, both male and female. Regular exercise was negatively associated with increase of psychosocial distress. In job characteristics, as expected, low decision latitude, high job insecurity, and low social support at work were related to high psychosocial distress. Personality traits such as locus of control and type A behavior pattern, and self-esteem were more powerful predictors of psychosocial distress than general characteristics, health-related behavior, and job characteristics. There were some gender differences. While men who are less educated and single (unmarried, divorced, and separated) experienced higher levels of psychosocial distress than those who are educated and married, women who feel high job demand experienced higher levels of psychosocial distress than those who feel low job demand.The proportion of the high stress group was higher than expected, and psychosocial factors like social support and personality characteristics (e.g. locus of control, type A behavior pattern and self-esteem) were more significant factors for psychosocial distress than other variables. This finding suggests that some psychosocial factors, especially inadequate social support, low self-esteem and lack of internal locus of control for the development of psychosocial distress, will also operate as an intervention strategy in the worksite stress reduction program. It is strongly required that worksite stress reduction programs should be established in at both occupational and level as well as in individual levels.

In 2009, Korea banned the import, transport, and use of asbestos, and the Asbestos Injury Relief Act (AIRA) was promulgated in 2011. Two environmental health centers for asbestos (EHCA), including Pusan National University Yangsan Hospital (PNUYH) and SoonChunHyang University Cheonan Hospital (SCHUCH), were adapted to find environmental asbestos-related diseases (ARDs) and to support the purposes of AIRA. EHCA conducted a health impact survey (HIS) on persons who resided or reside near asbestos factories or mines. A total of 13,433 persons have taken screening examinations in PNUYH EHCA, and 623 persons (4.6%) have had secondary examinations. Of the 21,014 persons who had screening examinations in SCHUCH EHCA, 2490 persons (11.8%) had secondary examinations. Some of those who tested positive for ARDs through HISs filed applications for the asbestos victims' medical pocketbook (AVMP). Approximately 116 and 612 persons received AVMPs as a result of PNUYH and SCHUCH examinees, respectively. EHCAs have conducted HISs, public relations, and education for asbestos victims, ordinary citizens, and physicians. As HISs are based on voluntary participation, they does not monitor high-risk groups. Active surveillance focusing on high-risk groups has been blocked by the personal information protection act. Although important work has been performed in finding environmental asbestos victims and increasing public awareness on asbestos, it is necessary to improve the current system and registration.

Background: The International Agency for Research on Cancer classifies asbestos as belonging to Carcinogen Group 2A for gastric cancer. We herein report a case of gastric cancer associated with asbestosis and describe the work-related and risk assessments of asbestos exposure for gastric cancer. Case presentation: The 66-year-old male patient in our case worked in asbestos spinning factories. His level of cumulated asbestos fiber exposure was estimated to be 38.0-71.0 f-yr/cc. Thus, the Excess Life Cancer Risk for lung cancer associated with asbestos exposure was 9,648×10-5, almost 9,600 times the value recommended by the United States of America Environmental Protection Agency (1 × 10-5). The relative risk of developing lung cancer for this patient was more than 25 f-yr/cc, a well-known criterion for doubling the risk of lung cancer. Conclusion: The patient's exposure to high-dose asbestos was sufficient to increase his risk of gastric cancer because as the risk of lung cancer increased, the risk of gastric cancer was due to increase as well. Therefore, occupational asbestos fiber exposure might be associated with gastric cancer in this case. [ABSTRACT FROM AUTHOR]

Asbestos causes several asbestos related diseases (ARDs). Not only occupational asbestos exposure but also environmental asbestos exposure can cause ARDs. In Korea compensation for workers with ARDs has been provided by workers' compensation. Because the asbestos damage relief act (ADRA) was enacted in 2011, ARDs by environmental exposure can now be compensated. Korea is the sixth country in the world to compensate environmental asbestos victims. In the ADRA, the list of compensable diseases eligible for relief consists of lung cancer, malignant mesothelioma, and asbestosis. Because the back ground and criteria of each ARD for relief is different, physicians need to be familiar with all of them in order to deal with ARD patients. In this paper, the properties of asbestos, history of ARDs, and contents of the ADRA are discussed. Although the relationships between occupational asbestos exposure and ARDs have been well established, those for environmental exposure have not. More specifically, the relationship between lung cancer and environmental asbestos exposure is still not clear because of strong confounders. The first wave of asbestos problems arose from occupational exposure directly involving asbestos production, the second wave arose from usage of asbestos products, and the third wave would be related to asbestos ubiquitous in the environment. In Korea the second wave is just beginning to swell. Physicians must to prepare for these waves to crest in the near future. [ABSTRACT FROM AUTHOR]

Majority of musculoskeletal diseases are degenerative and work related. Work-related musculoskeletal diseases (WRMSD) are one of the main causes of work-related illnesses in Korea. Risk factors of WRMSD are multifactorial and included in individual, ergonomic and psychological factors. The role of job stress as one of the psychological factors in the development of WRMSD is still poorly understood and there is still no consensus on the epidemiological data. However, it seems likely that the body responds to stress factors through four systems (central nervous, autonomic nervous, endocrine and immune) which are constantly interacting as a complex network. Models on occupational stress and WRMSD offer unique perspectives on the role of occupational stressors on WRMSD. So health care providers should recognize stress- WRMSD interactions through careful, directed inquiry. Because a few studies have shown that stress-related interventions have been associated with decreases in musculo-skeletal symptoms. [ABSTRACT FROM AUTHOR]

The purpose of this study is to analyze what aspects of occupational stress predict depression among Korean workers, and determine which components of occupational stress or job characteristics is more strongly associated with depression. In this cross-sectional study, a total of 8,522 workers (21–65 years of age) from a nationwide sample were recruited. A self-administered questionnaire was used to assess socio-demographics, job characteristics, depressive symptoms measured by the Center for Epidemiologic Studies Depression Scale, and occupational stress assessed by the Korean occupational stress scale (KOSS). Multivariate analyses show that inadequate social support (OR = 1.58, 95% CI = 1.52, 1.66) and discomfort in occupational climate (OR = 1.25, 95% CI = 1.18, 1.32) were more important risk factors for depression than organizational injustice, job demand and job control. Compared to the ‘business activities’ industries, ‘recreational, cultural and sporting activities’ (OR = 3.45, 95% CI = 1.80, 6.58), ‘hotel and restaurants’ (OR = 3.34, 95% CI = 1.92, 5.80), ‘real estate and renting and leasing’ (OR = 2.24, 95% CI = 1.13, 4.44), ‘wholesale and retail’ (OR = 1.85, 95% CI = 1.28, 2.67), ‘transportation’ (OR = 1.85, 95% CI = 1.11, 3.07), and ‘financial institute and insurance’ (OR = 1.60, 95% CI = 1.04, 2.48) industries had significantly greater risk of depression after controlling for gender, age, marital status, duration of employment and all subscale of KOSS. The finding that inadequate social support and discomfort in occupational climate is a better predictor of depressive symptoms than organizational injustice in Korea, indicates that the newly developed KOSS has cultural relevance for assessing occupational stress in Korea. Future studies need to understand factors such as “emotional labor” within certain industries where increased risk for depression is observed. [ABSTRACT FROM AUTHOR]

Public aspects of medicine ,RA1-1270 - Abstract
Background: Lower-limb varicose veins (VVs) are common and known to have a higher prevalence among people who work in occupations requiring prolonged standing. In the Republic of Korea, however, VV-related occupational factors have seldom been examined. This study was conducted to assess the prevalence of VVs among nurses, an occupational group considered to be at high risk of VVs, and determine the occupational risk factors of prolonged standing. Methods: Between March and August 2014, a questionnaire survey coupled with Doppler ultrasonography was conducted on the nurses working at a university hospital. Results: A total of 414 nurses participated in the survey and diagnostic testing. From the survey analysis and test results, the prevalence of VVs in nurses was estimated to be 16.18%. Significant factors for venous reflux were age [odds ratio (OR) = 1.06, 95% confidence interval (CI) = 1.03–1.10], pregnancy (OR = 2.15, 95% CI = 1.17–3.94), and delivery (OR = 2.02, 95% CI = 1.08–3.78). The statistical significance of these factors was verified after risk adjustment for sociodemographic factors (OR = 3.40, 95% CI = 1.27–9.09). Conclusion: Factors significantly associated with venous reflux were increasing age and prolonged working hours (≥ 4 hours) in a standing position (OR = 2.80, 95% CI = 1.08–7.25), even after risk adjustment for sociodemographic factors. This study is significant in that an objective diagnosis of VVs preceded the analysis of the risk factors for VV incidence, thus verifying objectively that VVs are associated with occupations requiring prolonged hours of working in a standing position.

Public aspects of medicine ,RA1-1270 - Abstract
Post-traumatic stress disorder (PTSD) is a serious problem not only among workers who experience industrial accidents but also among workers who witness such accidents. Early intervention is needed to prevent prolonged psychological problems. There has been no study conducted regarding the psychological problems of and interventions for bystander workers in Korea. This study introduces the experience of intervention on psychological problems at the Busan Workers' Health Center workers who witnessed their colleagues' death. An investigation and an intervention were conducted according to the Korean Occupational Safety and Health Agency (KOSHA) Guide. In total, 21 individuals including indirect observers showed statistical differences on scores of the Impact Event Scale Revised and the Patient Health Questionnaire 9 after the intervention. Future interventions and research involving a larger sample size over a longer period are needed. The KOSHA Guide could be a useful tool for urgent psychological intervention in the event of major workplace disasters.
