Few cases of asthma caused by the two-spotted spider mite (TSM) have been reported among nonfarmer apple-packing workers. This study investigated whether allergic sensitization due to the TSM occurs in workers at the Agricultural Products Processing Center. The polymerase chain reaction was used to analyze apples and leaves provided to the Agricultural Products Processing Center for the presence of TSM. Skin prick tests using TSM antigen were administered to 10 workers, and serum levels of total immunoglobulin E (IgE) and specific IgE for TSM antigens were quantified. Of the 10 workers, four tested positive for TSM in the skin prick test, three had elevated total IgE levels, and one had also elevated specific IgE levels to TSM. This confirms that apple-packing workers risk allergic sensitization due to TSM exposure. Preventive measures are recommended not only for apple farmers but also for nonfarmer apple-packing workers.

Background
We have developed the Korean safety ladder as part of development of new safety technologies that can be accepted in industrial sites and would like to introduce the testing process to secure safety.
Methods
The test load and horizontal force prescribed by ANSI A14.7 and EN131-7 standards for only the overturning stability test were applied to calculate the weight required for securing overturning stability according to standards and installation of outrigger with the variables of the height of platform, the angle of inclination of the worker, and the size of the platform.
Results
The weight of a Korean safety ladder required for securing overturning stability according to the height is as follows: as mentioned by the ANSI A14.7, it is stable regardless of the weight when an outrigger. By the EN131-7 standard, a 5-step ladder is stable regardless of the weight, but 54 kg or more of weight is required for an 8-step ladder when an outrigger is installed. When there is no outrigger, 122 kg and 251 kg are required for 5-step and 8-step ladders, respectively.
Conclusion
It is necessary to restrict inclined working on the platform at less than 66° of inclination angle by the EN131-7 standards and secure 43 kg or more of weight in the minimum width of a platform of 400 mm or expand the ladder width or open length of the outrigger.

Background
This study aimed to develop prediction models for the work-relatedness of shoulder diseases through machine learning algorithms.
Methods
The dataset comprised 7,270 cases of 8,302 individuals who applied for occupational diseases and received the final approval decision from the Korea Workers' Compensation and Welfare Service's Disease Evaluation Committee, which is related to shoulder musculoskeletal disorders between January 2020 and December 2021. In this study, demographic analysis and difference of approval rate by shoulder diseases were performed. Additionally, machine learning algorithms, including logistic regression, support vector machine, decision tree, random forest, and the XGBoost, were utilized to construct prediction models for work-relatedness assessment.
Results
The performance of each model was evaluated. XGBoost showed an accuracy of 81.64% and an area under the curve of 0.73, and random forest showed an accuracy of 84.46% and an area under the curve of 0.73. Key factors influencing work-relatedness assessment were employment period, physical burden score, gender, and age.
Conclusion
The application of various machine learning techniques showed high performance score, representing that it would be helpful to reduce the differences in judgment between occupational environment medicine physicians.

Background
Waste collectors face multi-faceted health risks including exposure to musculoskeletal disorders, respiratory diseases, and workplace injuries because of their hazardous work environment. The purpose of this study was to determine the risk factors that affect health of the waste collectors across Bangladesh.
Methods
Data on a cross-sectional survey obtained information from 481 waste collectors about their demographics, housing conditions, hygiene practices, security measures, and disease prevalence. Descriptive analyses and multi-level models are used.
Results
As per univariate analysis, 81.3% did not have access to clean water, 58.4% did not have access to sanitation, and 65.9% of people lived in unhealthy housing. According to bivariate analysis, there is an association between unhealthy working conditions i.e., respiratory illnesses (19.1% asthma, 29.7% cough), gastrointestinal issues (59.3% discomfort, 24.1% diarrhea), musculoskeletal disorders, and dermatological diseases, and unsafe working conditions (i.e., 60% no masks, 71% no gloves, and 75% no boots). Considering geographic clustering, multi-level modeling examined how different factors affected particular illnesses. The following were significant protective factors: better housing (80% lower odds of acute irritation), security measures (50% lower odds of gastrointestinal diseases), good hygiene (62% lower odds of dermatological diseases), and younger age (2% higher odds of respiratory diseases per year).
Conclusion
In summary, unsafe living and working conditions greatly push the risks of illness for waste collectors. These risks to occupational health can be reduced with targeted interventions that enhance housing, hygiene, security protocols, and working conditions.

Background
The SARS-CoV-2 viral outbreak has been conflicts with the past-tense narrative elsewhere in the abstract.; the infodemic. Misinformation about the virus and disease it causes (COVID-19) has been linked with authority-questioning beliefs, co-branding with conspiracies, and other misinformation across social media. Distrust in simple occupational and public health tools we have at our disposal (like well-fitting face masks) has proliferated. Despite attempts to curb the spread of untrue or misleading information on COVID-19, this messaging persists on social media.
Methods
Using a clean and cleared account, the 300 top posts under the hashtag #masksdontwork were collected on Instagram for thematic analysis over three weeks in June 2022, with three separate data collection dates. Themes contained in the posts were independently assessed by two coders and discrepancies were resolved by consensus.
Results
The most dominant theme among posts was mistrust, including “government lies” and “media lies.” Anti-masking rhetoric was the second most frequent theme, where “freedom” and “disbelief in data” were common sub-themes.
Conclusion
Science denial and propaganda shared among Instagram users may represent an onramp to consumption of broader conspiracy theories and government distrust, in addition to having negative health effects and social consequences for workers regardless of whether they wear masks. Social media algorithms promote similar misinformation or authority-questioning beliefs to users who view related content. Addressing the spread of health-related misinformation can assist in deconstructing myths and increasing trust in public health authorities and prevent the spread of communicable diseases among workers and the public.

Background
The aims of this study are to examine how occupation-related data and information for health (ODH) are collected and managed from census-based surveys and potential occupational illness and injuries (POIS) statistics, and to propose a national strategy for the systematic collection, analysis, and management of ODH by building on the Korean Standard Classification of Occupation (KSCO) and using a job exposure matrix (JEM).
Methods
The status of the collection and management of ODH registered as national statistics, drawn not only from the census-based general population and workforce, but also from POIS statistics was reviewed and evaluated.
Results
ODH from the Republic of Korea's Census of Population and Labor Force are collected and classified according to the KSCO. In contrast, national statistics on POIS are not systematically collected for KSCO coding, reflecting the lack of an KSCO and related guidelines on how to collect ODH. Key frameworks for the construction of both an KSCO and a reference JEM for public health surveillance are proposed.
Conclusions
Further research is needed to develop a national system for collecting and managing ODH, which will ultimately contribute to the use of a national KSCO and the construction of JEM for public health surveillance.

Informal wood furniture workers face various occupational health and safety risks that may impact their health and quality of life (QOL). Improving health literacy (HL) could help mitigate these risks. This study aims to assess HL levels and their relationship to QOL among this group in Thailand.
Methods
This cross-sectional study was conducted in 2023 and involved 175 informal wood furniture workers employed in Ban Ma, Lamphun province, Thailand. Data collection instruments comprised the Occupational Health Literacy Questionnaire (TOHLS-IF) and a questionnaire assessing informal workers' QOL. Analysis encompassed descriptive statistics alongside partial correlation analysis (p < 0.05).
Results
Respondents demonstrated high overall health literacy (2.34 ± 0.45). Considering eight dimensions of QOL in the sample, some variables, such as insufficient income, debt, and underlying disease, were prevalent at high percentages and seemed to diminish workers' QOL. After adjustment for gender, age, level of education, and work experience, most QOL dimensions correlated positively with workers' HL levels (p < 0.05); significant variables included career goal setting (rs = 0.27, p < 0.001), conflicts in workplace (rs = 0.20, p = 0.009), environmental satisfaction (rs = 0.41, p < 0.001), readiness to use internet (rs = 0.28, p < 0.001) and applications (rs = 0.29, p < 0.001), coworker's respect (rs = 0.15, p = 0.003), and goal setting to advance career (rs = 0.28, p < 0.001). No significant relationship was observed between prevalent QOL-diminishing factors and health literacy.
Conclusion
The observed link between HL levels and multiple dimensions of QOL among informal wood furniture workers underscores the need for targeted interventions. Policymakers and social initiatives should focus on promoting health literacy and relevant skills to enhance QOL within this population.
背景非正规木制家具工人面临各种职业健康和安全风险，可能影响他们的健康和生活质量（QOL）。提高卫生知识素养有助于减轻这些风险。本研究旨在评估HL水平及其与泰国人群生活质量的关系。方法本横断面研究于2023年进行，涉及175名在泰国兰埔省班马受雇的非正式木制家具工人。数据收集工具包括职业健康素养问卷（TOHLS-IF）和非正式工人生活质量评估问卷。分析包括描述性统计和偏相关分析(p <；0.05)。结果被调查者总体健康素养较高（2.34±0.45）。考虑到样本中生活质量的八个维度，一些变量，如收入不足、债务和潜在疾病，在很高的百分比中普遍存在，似乎降低了工人的生活质量。在调整性别、年龄、教育程度和工作经验后，大多数生活质量维度与员工的HL水平呈正相关(p <；0.05);显著变量包括职业目标设定(rs = 0.27, p <；0.001)、工作场所冲突（rs = 0.20, p = 0.009）、环境满意度(rs = 0.41, p <；0.001)，使用互联网的准备程度(rs = 0.28, p <；0.001)和应用(rs = 0.29, p <；0.001)、同事的尊重（rs = 0.15, p = 0.003）和职业发展目标的设定(rs = 0.28, p <；0.001)。普遍的生活质量降低因素与健康素养之间无显著关系。结论非正式木制家具工人的HL水平与生活质量的多个维度之间存在联系，因此需要有针对性的干预。决策者和社会举措应侧重于促进卫生知识普及和相关技能，以提高这一人群的生活质量。

Background
Exposure to cooking fumes exposure likely increases the lung cancer risk in school cooks, but research on the incidence of lung cancer in school cooks is lacking. Therefore, this study aimed to examine a nationwide cohort of school cooks for lung cancer by linking three Korean social insurance databases to determine whether working as a school cook increases lung cancer risk.
Methods
A nationwide retrospective cohort of school cooks and clerks with lung cancer was established by linking Employment Insurance, Industrial Accident Compensation Insurance, and National Health Insurance Service databases. Covariates were matched using 1:1 propensity score matching (PSM) for school cooks and clerks. Age-standardized incidence and hazard ratios (HRs) for lung cancer were calculated using the Cox proportional hazards model. Fine–Gray subdistribution HRs were used for sensitivity analysis. After further categorization into never- and ever-smoked subcohorts, the same analyses were performed.
Results
Post PSM, we identified 76 cases of lung cancer in school cooks during 259,819 person-years of follow-up. The age-standardized incidence was 199.8 (95% confidence interval [CI]: 120.7–278.9) and 166.8 (95% CI: 95.8–237.7) for school cooks and clerks, respectively. The subdistribution HR for school cooks post PSM was 1.72 (95% CI: 1.14–2.60). In the never-smoked subcohort, the subdistribution HR for school cooks post PSM was 4.23 (95% CI: 2.36–7.58).
Conclusion
School cooks were at an elevated risk of developing lung cancer, likely due to exposure to cooking fumes, highlighting the need for improved ventilation and preventive measures in school kitchens to reduce lung cancer risk.

Background
Standardized exposure assessments were conducted to quantify the historical occupational exposure to hand-arm vibration of workers in the German construction, underground coal mining, woodworking, and metalworking industries.
Methods
A two-step approach was used to assess historical vibration exposure. In the first step, individual work histories were reconstructed by standardized personal interviews. The interview focused on the identification of relevant power tools used throughout the working life. In the second step, an equipment-exposure-matrix was constructed by industrial hygiene measurements. By linking the power tools in the work history to the equipment-exposure-matrix, individual daily, and long-term vibration exposures can be quantified.
Results and conclusions
A total of 423 power tools were identified for 5,115 exposure segments over a period of 50 years. 97.2% of the vibration values were based on industrial hygiene measurements. The total vibration value (ahv) of the power tools used varied between 0.8 m/s2 and 65.2 m/s2 with a median value of 14.2 m/s2. The median value of cumulative vibration exposure is Dhv = 121,971 (range: 23-3,374,640) m2/s4·day, corresponding to a daily vibration exposure of ahv(8) = 7 m/s2 for 2489 working days (11.3 years).
This study provides a detailed description of hand-arm vibration exposure among workers in the related industries studied. Our analyses indicate that the quantification of daily vibration exposure is often uncertain and should be interpreted with caution. In contrast, cumulative vibration exposure is a more reliable exposure parameter for describing general working conditions and for guiding the prevention and compensation of vibration-related health problems.

Psychosocial safety climate (PSC) refers to the collective belief among workers regarding the protection and support of their psychological health and safety by senior management. Despite the recognized importance of PSC in mitigating exposure to detrimental psychosocial risk factors at work, a validated instrument in French is lacking. This study aimed to evaluate the psychometric properties of the French-Canadian version of the PSC-12 and its associations with job satisfaction and psychological distress.
Method
A cross-sectional validation study was conducted to evaluate the psychometric properties of the PSC-12. Using cross-sectional data from an online survey of adults in a French-Canadian university (n = 1,784), the psychometric properties of the PSC-12, a 12-item questionnaire, were assessed. Internal consistency, validity, and factor structure were examined through exploratory factor analysis conducted using SAS v.9.4 software.
Results
Confirming the original four-factor structure, the French-Canadian version of the PSC-12 demonstrated satisfactory internal consistency (Cronbach's α of 0.95) and validity indices. Its convergent and divergent validity was evidenced by a positive association with job satisfaction (r = 0.34, p < 0.05) and the negative association with psychological distress (r = -0.50, p < 0.05).
Conclusions
The French-Canadian adaptation of the PSC-12 maintains cross-cultural validity, providing a validated and concise tool for assessment within the French-Canadian community. Practical Applications: By facilitating the prevention of mental health problems among workers, this questionnaire has the potential to contribute to alleviating burdens for individuals, workplaces, and society.
心理社会安全气候（PSC）是指工人对高层管理人员对其心理健康和安全的保护和支持的集体信念。尽管PSC在减轻工作中有害社会心理风险因素暴露方面的重要性得到公认，但缺乏一种经过验证的法语工具。本研究旨在评估法加版PSC-12的心理测量特性及其与工作满意度和心理困扰的关系。方法采用横断面验证法对PSC-12的心理测量特性进行评价。使用来自一所法裔加拿大大学的成年人在线调查（n = 1,784）的横断面数据，评估了PSC-12（一份包含12个项目的问卷）的心理测量特性。采用SAS v.9.4软件进行探索性因子分析，检验内部一致性、效度和因子结构。结果法加版PSC-12的内部一致性（Cronbach’s α = 0.95）和效度指标均令人满意，证实了原来的四因子结构。其收敛效度和发散效度与工作满意度呈显著正相关(r = 0.34, p <；0.05)，与心理困扰呈负相关(r = -0.50, p <；0.05)。结论：法裔加拿大人对PSC-12的改编保持了跨文化有效性，为法裔加拿大人社区内的评估提供了一个有效的、简洁的工具。实际应用：通过促进工人心理健康问题的预防，本问卷有可能有助于减轻个人、工作场所和社会的负担。
