Financial Sustainability of Social Insurance: The Case of Korean Workers’ Compensation Insurance and Possibility of Triple Moral Hazard

Abstract This study examines the economic stability of Korean Workers’ Compensation Insurance (WCI), highlighting the system’s vulnerability to triple moral hazard. Korean WCI features more generous worker compensation, lower employer premiums, and more active government involvement in accident prevention in addition to a higher industrial accident rate, compared to the system in Germany and Japan. The negotiation process of the WCI among workers, employers, and insurance managers often prioritizes short-term benefits, undermining long-term financial health. Workers seek greater compensation, employers push for lower premiums, and insurance managers may prioritize collective interests, exacerbating the system’s economic instability. Over recent years, applications for occupational disease recognition have surged, and premium rates have decreased, indicating increasing strain. To mitigate these issues, the study proposes enhancing transparency and rationality, involving non-political experts in decision-making, and clearly defining the government’s role in managing WCI. These measures aim to balance stakeholder interests and ensure the WCI system’s sustainability for future generations.

Resources and activities of voivodeship occupational medicine centers in Poland during the COVID-19 pandemic

Voivodeship Occupational Medicine Centres (VOMC), being higher-level units towards basic units providing preventive care for employees in Poland, play a consultative, appeal, supervisory and registration role towards them. Additionally, they perform many other tasks specified in the Occupational Medicine Service Act, including conducting diagnostic and jurisprudential activities related to occupational diseases and postgraduate education in occupational medicine. The analysis covers data from 2017-2022 on VOMCs activities, derived from mandatory MZ-35 reporting. Over 6 years, the number of employed physicians at VOMCs decreased from 830 in 2017 to 820 in 2022, with >20% of employment contracts transitioning to other forms of cooperation. The number of employed nurses decreased from 375 to 342, and the number of psychologists from 86 to 82. During the 3 years of the pandemic (2020-2022), compared to 2017-2019, the consultative activity of VOMCs for basic units of occupational health service decreased by nearly 30%, while appeal and supervisory activities decreased by 15.2% and 15.8%, respectively. The number of individuals receiving outpatient medical rehabilitation for occupational pathology decreased by >32%, and the number of services provided for established occupational pathology decreased by >14%. The number of certifications for occupational diseases decreased from 3963 in 2019 to 3518 in the first year of the pandemic, then increased to 4145 in 2021 and 3990 in 2022. The COVID-19 pandemic had a significant impact on the functioning of VOMCs. Changes in specific areas of their judicial, consultative, appeal, supervisory, training and rehabilitation activities corresponded with the socio-legal changes observed between 2020-2022. The structure of employment at VOMCs and the scope of their tasks remained stable during the pandemic. The observed changes in employment of medical staff were in line with general trends in healthcare institutions and regional conditions. Med Pr Work Health Saf. 2024;75(4):367-381.

MMP1 and SOD2 genes polymorphism in occupational diseases pathogenesis in workers of mining and processing enterprises

Introduction. Vibration disease (VD) is occupational disease that develops with prolonged exposure to industrial vibration. VD is one of the most common occupational pathologies. This disease is characterized by pathogenetic mechanisms complexity, polymorphic symptoms, chronic course, therapeutic resistance, and often leads to disability of patients. As a rule, changes in the cardiovascular and nervous systems, musculoskeletal system and metabolic processes are observed with VD. The aim of study was to find associations of polymorphic variants rs1799750 of MMP1 and rs4880 of SOD2 genes with vibration disease. Materials and methods. 73 people with various forms of VB were examined. The control group consisted of 73 people who were not exposed to vibration in their professional activities. The distribution of polymorphic loci rs1799750 of MMP1 gene and rs4880 of SOD2 gene was studied. Statistical analysis was performed using the IBM SPSS Statistica v.21 and Microsoft Excel software packages. Results. It was revealed that *d allele of rs1799750 of MMP1 gene associated with VD (p=0.046), but its frequency is lower among VD patients with sensorineural hearing loss compared to VD patients without this syndrome (p=0.035). The frequency of *T/*T genotype and the *T allele of rs4880 is increased among patients with peripheral angiodystonic syndrome of VD. Limitations. The limitations of this work include the small sample size and the fact that the study participants from the control sample work at a different enterprise, which does not allow us to exclude the influence of other environmental factors, but allows us to consider them as a reference population. Conclusion. Thus, we were unable to identify a direct association of the studied genotypes with VD, but the association with peripheral angiodystonic syndrome suggests that these polymorphisms affect the pathogenesis of VD.

Development of Dust Emission Prediction Model for Open-Pit Mines Based on SHPB Experiment and Image Recognition Method

Open-pit coal mining offers high resource recovery, excellent safety conditions, and large-scale production. However, the process generates significant dust, leading to occupational diseases such as pneumoconiosis among miners and adversely affecting nearby vegetation through dust deposition, which hinders photosynthesis and causes ecological damage. This limits the transition of open-pit mining to a green, low-carbon model. Among these processes, blasting generates the most dust and has the widest impact range, but the specific amount of dust generated has not yet been thoroughly studied. This study integrates indoor experiments, theoretical analyses, and field tests, employing the Split Hopkinson Pressure Bar (SHPB) system to conduct impact loading tests on coal–rock samples under pressures ranging from 0.13 MPa to 2.0 MPa. The results indicate that as the impact load increases, the proportion of large-sized blocks decreases while smaller fragments and powdered samples increase, signifying intensified sample fragmentation. Using stress wave attenuation theory, this study translates indoor impact loadings to field blast shock waves, revealing the relationship between blasting dust mass fraction and impact pressure. Field tests at the Haerwusu open-pit coal mine validated the formula. Using image recognition technology to analyze post-blast muck-pile fragmentation, the estimated dust production closely matched the calculated values, with an error margin of less than 10%. This formula provides valuable insights for estimating dust production and improving dust control measures during open-pit mine blasting operations.

Health risks from exposure to industrial aerosols of soluble and insoluble nickel compounds

Introduction. Despite the implementation of active preventive measures, employees of nickel enterprises, remain to belong to a group of increased risk of occupational pathology. Aim. comparative analysis of the risks to occupational health in workers exposed to soluble and insoluble nickel compounds in various specialties of the nickel industry. Materials and methods. A retrospective observational study of the health status and development of occupational pathology was carried out among seven hundred sixty three workers of pyrometallurgical and 1395 workers of electrolysis nickel processing plants during 2008–2023. Results. Over the course of 15 years, 112 and 221 occupational diseases were first identified in 57 (7.5%) of 763 pyrometallurgical workers and 100 (7.2%) of 1,395 nickel electrolysis workers. The risk of developing occupational pathology among workers of the two industries did not differ: RR 1.04; CI 0.76-1.43; p=0.797. In 2009–2023 There were no significant trend in the number of workers with primary occupational diseases and their number. Of all the specialists, the greatest risk of occupational pathology was found among finished product cleaners and smelters. The maximum level of occupational morbidity was found among cleaners and smelters (323.62 and 229.69 cases / 10,000 workers), and the minimum – among repairmen, crane operators, roasters (pyrometallurgical production) and electricians of electrolysis production (35–45 cases / 10,000 workers). Limitations. The number of observations in some groups of specialists is insufficient for statistical processing. Conclusion. The risk of developing occupational pathology does not depend on the solubility or insolubility of nickel compounds in industrial aerosols, but is largely determined by the final class of working conditions and the specialty of the worker. When carrying out measures to reduce health risks, it is necessary to take into account not only the class of working conditions, but also their characteristics for specialists at various technological stages of nickel production.

Working conditions and health status in workers in boiler and welding production in power engineering

Introduction. Preserving the health of qualified workers of older age groups is especially important under conditions of exposure to occupational hazards. The purpose of the study was to assess the influence of occupational hazards on the development of occupational and somatic diseases among workers of various age groups in the main occupations of mechanical engineering. Materials and methods. The study tested the results of hygienic research at workplaces of an enterprise in the power engineering industry in the manufacture of welded metal structures. We assessed the health status in workers based on the results of an in-depth medical examination and ultrasound examination of the vessels of the upper extremities with assessment of blood flow indices. Using a survey method, data were obtained on assessing the influence of production factors on the health status in workers. Results. The working conditions in the main occupational workers groups were assessed as harmful grades 1–3, the priority occupational hazards were: increased noise, and at the workplaces of electric gas workers there were also fibrogenic aerosols, chemical substances, and heavy physical work. Electric and gas welders and boilermakers work in the most unfavourable conditions, about 30% of whom continue to work after reaching retirement age. We have established a significant gain in the incidence of arterial hypertension and sensorineural hearing loss among workers over 40 years of age and an increase in the prevalence of all chronic diseases in the age group over 60 years. Limitations. The study is limited by the number of workers examined and the lack of ability to assess the health status of the studied contingent of workers over time. Conclusion. In conditions of exposure to elevated noise and other occupational hazards, there is an enhancement in the prevalence of work-related and somatic diseases in workers over 40 years of age. With advancing age, the rise in the vascular resistance index is observed, however, the first signs of peripheral blood flow disturbance are often recorded at a young age. In this regard, it is necessary to introduce methods of early diagnosis and prevention of occupational and work-related pathology.

Matching Occupational Injury and Illness Data Using Augmented Twin Neural Networks

When record linkage efforts involve complex characteristics there is ample potential for general purpose machine learning (ML) techniques to succeed where traditional probabilistic approaches might fall short. However, there can still be pre-processing (e.g. geocoding) and hand-picked comparators that can further improve linkage outcomes using standard ML models. In this project we present a fusion of these sides we are calling an Augmented Twin Neural Network. This approach leverages the inherent flexibility of Twin Neural Networks in a record linkage context while adding additional layers to allow for hand curated comparators that may be difficult for ML optimizers to implicitly identify without sufficiently large, labeled data sets. The framework is used to match establishments from the BLS Survey of Occupational Injuries and Illnesses to establishments in the OSHA Injury Tracking Application data. The difficulties inherent in matching company names and addresses and the existence of multi-establishment firms make this a prime application for testing. Linkage outcome metrics of this augmented algorithm are compared both with results from probabilistic methods (e.g. Fellegi-Sunter) and standard machine learning methods to illustrate the added benefits.

ECHO OEM virtual community of learning for primary care.

Health issues caused and/or exacerbated by work are common in patients seeking primary health care. Yet, primary care providers generally receive little or no training in the assessment and management of occupational injuries and illnesses. To conduct a pilot project to develop, implement and evaluate a programme to teach occupational and environmental medicine to primary healthcare providers. We followed the Extensions for Community Healthcare Outcomes (ECHO) model to connect primary healthcare providers with experts in Occupational and Environmental Medicine (OEM). We employed an observational pre-post study design to assess changes in self-efficacy, knowledge, attitudes and beliefs towards OEM. From September 2021 to June 2022, we offered two cycles of 12 sessions each. Participants came from medicine, nursing, psychology, occupational and physical therapy, chiropractic, kinesiology, social work, and pharmacy. Sixty-seven participants completed both pre- and post-ECHO questionnaires. Self-efficacy and knowledge ratings significantly increased after attendance at ECHO compared to the pre-ECHO responses. Attitudes and beliefs were unchanged in most of the items assessed. Participants rated their satisfaction with ECHO between 59% and 97%. Our pilot study demonstrated the challenges in implementing the first ECHO OEM in Canada. Findings show acceptability and satisfaction, improved self-efficacy, and small increases in knowledge, but not overall attitudes and beliefs. There is a need to understand barriers to participation and to target participants with less knowledge and experience in occupational and environmental medicine.

Medico-legal evaluation of occupational skin diseases and occupational skin cancer.

The medico-legal evaluation of occupational skin diseases is one of the core competencies of dermatology. As a neutral medical expert, the dermatologist has a different role to that of a treating physician. In Germany, the so-called Bamberg Recommendation (Bamberger Empfehlung) provides a scientifically based assessment basis to ensure equal treatment of all persons undergoing medico-legal evaluation. In addition to dermatological expertise, knowledge of insurance law and legal terminology is essential for the medical expert. Dermatologists provide legal and administrative decisions of social courts and social insurance institutions with their qualified expert opinions. In this way, dermatology makes an important contribution to social security.

Accidents with Lepidoptera (Insecta): Biology, Poisonous, Clinical Manifestations, Treatment, Prevention, and Therapeutic Possibilities

Accidents triggered by contact with winged adult forms of moths and accidents caused by contact with larvae. These accidents are caused by contact with the bristles on the abdomen of females of certain species, belonging to the genus Hylesia Hübner, 1820 (Family: Hemileucidae). Therefore, the simple fact of penetration of the bristles seems to be capable of causing intense inflammatory, popular, and pruritic reactions. Pararama (pararamose) is the common name for a stinging caterpillar found in the artificial rubber plantations of Pará, Brazil, the larval stage of the moth Premolis semirufa (Walker, 1856) (Famíly: Erebidae). Therefore, accidental contact with the small bristles of the caterpillars or with those of the cocoons causes a chronic inflammatory reaction in the interphalangeal joints that leads to ankylosis. The morbid condition mainly affects rubber tappers and is classified as an occupational disease. Eruca=larva; erucism is poisoning caused by a moth larva. The main families of Lepidoptera fireworms that cause erucism accidents are Megalopygidae, Saturniidae, and Arctiidae. The caterpillars of the Megalopygidae family have a body covered with long, harmless bristles that cover the smaller, sharp spines that carry poison glands this manuscript aims to report the biological characteristics of venomous Lepidoptera (Insecta) and their biological, clinical manifestations, treatment, prevention, and therapeutic possibilities.

MODERN CONCEPT OF OCCUPATIONAL SAFETY AND HEALTH MANAGEMENT WITH A RISK-BASED APPROACH

The article justifies implementing a risk-based approach (RBA) in occupational safety and health (OSH) management. It considers the limitations of traditional methods of implementing preventive measures focused on reactive measures designed to respond to immediate security challenges. It further proposes modern proactive strategies that can monitor, predict, and prevent dangerous situations in the workplace in advance. The study develops and substantiates the RBA’s main principles and underscores elements, methodologies, and their integration into existing OSH management systems. It provides arguments to support decentralising decision-making closer to the sources of hazards to allow for a faster and more effective response. It also emphasises the fragmented nature of the current occupational safety and health legislation, making it challenging to integrate RBA. Recommendations suggest improving the legislative framework to support RBA and provide employers greater flexibility in choosing risk management tools and methods. The authors recognise a systematic risk monitoring and assessment approach as a critical need. The absence of regular audits and risk assessments hinders the identification and prevention of hazards. The study proposes the introduction of modern technologies and methodologies, such as the Fine and Kinney method, the Elmeri system, and the Ishikawa diagram, to improve the risk identification and assessment processes. The article also stresses the importance of informing employees about potential risks and preventive measures, which contributes to the overall safety culture in organisations. In addition, the authors outline an algorithm for implementing RBA, which includes auditing workplaces, creating electronic registers, developing safety instructions, systematic risk assessment, documenting results, and informing stakeholders. The proposed approach aims to proactively identify and mitigate occupational risks, which helps to reduce workplace accidents and occupational diseases. The article concludes that the transition to a risk-based approach is essential for improving workplace safety, reducing occupational risks, and supporting the sustainable development of enterprises. By applying RBA, organisations can achieve higher occupational safety, reduce the costs associated with accidents and injuries, and contribute to a safer and healthier work environment. Keywords: risks, occupational safety, occupational health, production, risk-based approach.

Behaviour of Using Personal Protective Equipment by Midwives During Normal Childbirth Based on Health Belief Model and Social Capital at Maternity Clinics

The implementation mechanism of normal childbirth care is inseparable from the potential risks to midwifery health disorders. One of the efforts to prevent health problems due to work is to use Personal Protective Equipment (PPE). The behavior of using PPE by midwives is important to prevent work accidents or occupational diseases during normal childbirth assistance which can be reviewed from a person's health behavior. Theories that can describe health behaviors are the Health Belief Model and Social Capital. The purpose of this study is to analyze the influence of the theory of Health Belief Model and Social Capital on the behavior of using PPE in midwives in normal childbirth care at the Surabaya City maternity clinic. The research design uses clinical observation with a cross sectional approach. The population consists of 80 midwives and the sample consisted of 66 respondents. All aspects of HBM and social capital have a sig > 0.05 which means that these aspects are related to the behavior of using PPE in midwives in normal childbirth care at the Surabaya City maternity clinic. All aspects of HBM and social capital have a sig of < 0.05 which means that these aspects affect the behavior of using PPE in midwives in normal childbirth care at the Surabaya City maternity clinic. The vulnerability aspect of HBM theory and the proactive action aspect of Social Capital theory significantly affect normal childbirth care.

The economic burden and other severe problems caused by COPD are introduced. Subsequently, seminal research in relevant areas is reviewed. The prospects and challenges are introduced and discussed based on critical management approaches. An initial design of an Industry 4.0-compliant occupational COPD prevention system is presented at the end.

OCCUPATIONAL DISEASES

Occupational diseases continue to be one of the major health problems of the able-bodied population worldwide. The reasons for this are numerous, but the main one is of course the nature of these diseases which by definition are chronic, progressive and degenerative, and the period of latency in which the disease does not have to manifest clinically can last for decades. The factors that can contribute to the development of an occupational disease, ie disease, are numerous and range from chemical, physical and biological to psychosocial risks, so there is a need to find new ways to control long-known risks, to observations of the most common workplace pathologies in the last twenty years, such as recurrent traumatic illnesses, immunodeficiency transmitted as a result of biological injuries and violence, and psychological trauma in the workplace. The aim of this paper is to evaluate the effect of noise as a function of its levels and the duration of workplace exposure on workers' health. This study was conducted with 10 workers from the metal factory "Zhelezara", Skopj which have been exposed to the noise the longest period. According to the results of the research, it can be noted that workers working in a noisy environment experience certain side effects from the noise, although they use different protective equipment for the entire duration of the working time. New knowledge in occupational health and safety practice is needed to respond to new challenges in this field.

Risk assessment of arsenic exposure to occupational disease artisanal and small-scale gold mining sites, Bombana Area, Southeast Sulawesi, Indonesia

Abstract Anthropogenic activities can lead to heavy metal accumulation in the body, causing heavy metal poisoning and occupational diseases. This study investigated the impact of Arsenic exposure on artisanal gold miners in Southeast Sulawesi, Indonesia. The study focused on miners at two Artisanal and Small-scale Gold Mining sites in Bombana area. The study sample comprises 63 individuals, with 54 individuals representing miners from the Rarowatu and North Rarowatu regions constituting the exposed group and 9 individuals representing non-miners from the Rumbia region forming the control group. Medical examinations and questionnaires were used to identify symptoms of occupational diseases. The As concentrations in human hair samples revealed that miners with over ten years of experience had significantly higher As concentrations (2.67 μg/g) than those exposed to less than ten years of durations (1.26 μg/g). The As concentration in the exposed group (1.61 μg/g) exceeds the World Health Organization guidelines (1 μg/g) and is higher than that of the control group (0.87 μg/g), although not statistically significant (p<0.05). Additionally, there were no significant differences in As concentrations between sick and healthy workers with various symptoms (neurological, respiratory, musculoskeletal, degenerative, and others) (p-values: 0.08, 0.32, 0.69, 0.36, and 0.67, respectively). Long-term Artisanal and Small-scale Gold Mining miners had higher As exposure, but this study found no clear association between As concentrations and specific occupational diseases.

Implementation of Evacuation Training in Emergency Situations to Improve Ship Passenger Safety on KMP Jatra 2

The incidence of accidents and occupational diseases is still quite high. Various ship incidents include sinking, collision, fire, aground, people falling overboard, steering damage, and pollution at sea. as well as work accidents during duty on the ship, generally caused by human factors or human error. The purpose of this study is to find out the emergency drills on the ship, based on SOLAS on the KMP Jatra 2 ship and to find out how to handle problems in maximizing job training to each crew member according to SOLAS and SOP regulations. The results of this study found that emergency training on board KMP Jatra 2 is not running properly due to lack of consistency in following the SOP and SOLAS standards that have been set. To deal with this problem, several steps need to be taken, namely good HR policies, implementation of a punishment system for undisciplined crew members, regular training and realistic simulation of emergency situations, continuous supervision and evaluation of training implementation.

Occupational respiratory disease in Eastern Slovakia between 1990-2021: a shift from agriculture to industrial manufacturing.

Occupational allergic respiratory diseases frequently occur in individuals working in the agricultural and food production sectors, textile manufacturing, and industries involving exposure to isocyanates. The study aimed to describe trends surrounding the prevalence of occupational asthma (OA), occupational rhinitis (OR), and occupational hypersensitivity pneumonitis (OHP) in Eastern Slovakia between 1990-2021. All cases of OA, OR, and OHP registered in a database at the Louis Pasteur University Hospital in Košice, Slovakia, between 1990 and 2021, were divided into categories based on economic sector (agricultural, food production sectors, textile manufacturing, healthcare, industrial manufacturing, and tertiary sector) and causal agent. Changes in disease prevalence, causal agents, and economic sector association over time were analysed. There were 287 occupational respiratory cases (179 OA, 65 OR, and 43 OHP cases). The annual prevalence of OA declined significantly over the study period (p < 0.05). Overall, there was a significant decrease in cases from the agricultural (p < 0.001) and an increase in the industrial manufacturing (p < 0.01). The number of cases due to farming agents fell markedly over the study period, while metalworking fluids (MWFs) were found to be the most common causes of allergic respiratory diseases since 2018. This study found a decrease in the number of OA cases, as well as changes in economic sectors and causal agents associated with OA and OHP, specifically, in the agricultural sector, with MWFs from the industrial manufacturing sector now being the most common aetiological agent.

보건·의료계열 종사자의 정신적 웰빙을 저해하는 산업안전 유해요인 분석 - 의사, 간호사, 의료기사를 중심으로

The industrial safety of health and medical workers who struggling on the front lines of diseases and disasters to protect public health and life, is threatened by working environment hazard factors that damage health. Despite they are exposing to hazard factors and accumulating mental well-being risks frequently, the social discussions and national efforts for their health were insufficient due to complacent perceptions that “They would be safe from occupational diseases and industrial accidents because of the working environment characteristic that set as medical work”. Korean society needs to enhance the importance of industrial safety because if the mental well-being risk of health and medical workers is not healed in proper time, the deterioration of work engagement can harm personal health and patient life and threat public health and cause a national crisis. Therefore, this study analyzed occupational safety hazard factors that hinder health and medical worker's mental well-being focusing on doctor, nurse, medical technician based on Rutter's ‘Cumulated Risk Model’ that explaining the more accumulate of exposure to simultaneous risk factors, the greater ripple effect of human's internalization and externalization problem. The multiple regression analysis were performed with SPSS Statistics 29.0 for 749 health and medical workers who attended the 6th Korean Working Conditions Survey published by the Korea Occupational Safety and Health Research. As a result, the health and medical worker's mental well-being were hindered whey they exposure to occupational safety hazard factors, emotional labor and quantitative labor intensity were finally verified as occupational safety hazard factors that threatened the mental well-being of them. Based on the results, this study suggested ① services and policies to effectively counter occupational safety hazard factors that hinder the health and medical worker's mental well-being, ② prevention and solution plan about exposure problem to occupational safety hazard factors, ③ customized strategies to promote health and medical workers' mental well-being.
