Recent studies suggest that prolonged standing at work is associated with varicose veins (VV). The objective of this study was to analyze the differences of VV risk in terms of work types in casino dealers and hotel service workers. Symptoms of VV were evaluated using a self-reported questionnaire from 2,092 participants, and muscle fatigue in the lower legs were evaluated using surface electromyography. The shift rate of median frequency in Gastrocnemius was -30.0% among the casino dealers working in prolonged static standing posture, and - 14.3% among the casino dealers sitting during working time. After adjusting age, gender, smoking, and family history of VV, the risk ratio of VV was 3.67(95% CI 2.03-6.59) in group I (prolonged standing and occasional walking at work), 6.29(95% CI 3.48-11.35) in group II (prolonged standing, occasional walking and heavy lifting at work), and 8.07(95% CI 4.51-14.43) in groupIII(prolonged static standing at work). In conclusion, prolonged standing at work may be a work related risk factor of VV.

The main purpose of this study is to describe the different life chances among various occupational groups in Chonbuk Province which has been excluded in the process of Korea's industrialization since the 1960s. More specifically, this study analyzed to what extent 6 occupational groups have the different life chances in the sub-levels such as health conditions and leisure life. According to our data analysis, it is found that the 6 occupational groups have the different life chances. That is, while those who are engaged in the higher prestigious occupation have a good life chance, those who in the lower prestigious occupation have a worse life chance. For example, among 6 occupational groups, professional-managerial who secure the higher autonomy and stability in their work have the highest life chance in the labor and health, and leisure life. Next, professional-technical, white-collar, sales-service occupants have the higher life chance after the professional-managerial. However, these 3 occupation groups are partially inconsistent in the two sectors of the life chance. Specifically, the professional-technical, despite their autonomy and stability in the work world, conceived that their work conditions are worse as well as badly influencing on their own health. On the other band, the sales-service workers group, despite their lower social status, is relatively autonomous and stable in their work environment and thus has the higher life chances. Finally, agricultural and productive workers have relatively the lower lift chances. Nevertheless, there are some clear differences among these 2 occupational groups. That is, the farmers have relatively the higher life chances in the sectors of socio-economic characteristics, and labor and health rather than productive workers. As a result, the productive workers are generally located in the lowest level of life chance. This fact is particularly attributed to the fragility of manufacturing industries in Chonbuk Province.

This study aimed to identify the recognition of fire risks on their field operations among firefighters and contribute to setting up safety measures accordingly. A self-administered questionnaire were used to evaluate their recognition of job risks. About 93.4% of respondents answered they have exposed to job risks and 73.4% answered that they had high safety awareness. Our study showed that the lower service years and ranks the fire officers had, the lower relevance in statistics their awareness of the risk of the field operations and safety concerns had. The vulnerable group is those aged 20 to 39, with under 10 years of service, at a lower rank of senior fire sergeant. The study suggests coming up with the measures to motivate the officers to perform safe operations by improving their safety awareness.

Purpose: This study aimed to assess the risk of developing cardiovascular disease (CVD) and to evaluate the effects of intervention for CVD prevention in construction workers. Methods: A total of 497 workers participated the health status survey and finally 90 workers were analyzed for evaluation of the intervention with the one-group pretest-posttest design. The data were collected from the questionnaires and health examinations in the healthcare service for road constructor's CVD prevention as secondary analysis. The intervention of the healthcare was composed of CVD prevention education for all workers and face to face counselling for the high risk group of CVD risk during 6 months in workplace. Data were analyzed with descriptive statistics, $x^2$ test, Wilcoxon signed rank test, and paired t-test. Results: The moderate and high risk groups of CVD were 9.7% and 0.8%. After the intervention, the physical activity (MET-min/week) significantly increased (Z=-5.46, p<.001). But, there were no significant differences in blood pressure, fasting glucose, body mass index, and CVD risk appraisals between pre and post intervention. Conclusion: The findings imply that it is necessary to develop the health promotion program for construction workers which fully reflects the characteristics of individuals and the organization.

Background: Nursing service is a nonroutine work with an excessive physical load and diverse tasks. This study derived representative common tasks based on the frequently occurring tasks with a high physical load in the nursing workers' daily work and developed indicators to evaluate the work risk by reflecting the characteristics of nonroutine work. Methods: Common tasks were classified through the following stages: literature review, first focus group interview (FGI) with experts, first classification of common tasks, second FGI with hospital health managers, a survey of nursing service workers, and the final classification of common tasks for each task type. To develop an objective risk index for physical load assessment, we investigated the frequency and duration of the derived common tasks via survey. Results: Nursing common tasks were categorized into six task types and 56 subtasks. To evaluate the risks of various tasks in nonroutine works, three frequencies and three working time levels were defined by examining the task frequency and working hours. Exposure time was defined to reflect the characteristics of a nonroutine job. The final risk assessment was the product of the exposure time level and job intensity level. From this, four risk action levels were derived. Conclusion: This study has the advantage of solving the problem of focusing on some tasks in evaluating the physical load. It was meaningful in that a new risk assessment index based on exposure time was proposed based on the development of an evaluation scale for frequency and time by reflecting the characteristics of nonroutine work.

Background: Gasoline, a complex mixture of volatile organic compounds is classified as possibly carcinogenic to humans. Gasoline station attendants, consistently exposed to its hazardous components, may face genotoxic effects. This study aimed to assess the influence of varying work shift durations on DNA damage in gasoline station attendants. Methods: Ninety individuals from three locations in southern México were studied. Peripheral blood mononuclear cells (PBMCs) were isolated, and DNA damage was assessed using the comet assay. Demographic, occupational, and lifestyle data were collected. Statistical analyses included t-tests, ANOVA, and Pearson correlation. Results: Significant differences in DNA damage parameters were observed between exposed and unexposed groups. The impact of tobacco, alcohol, and exercise on DNA damage was negligible. Extended work shifts (12 and 24 hours) showed heightened DNA damage compared to 8-hour shifts and the unexposed group. A novel finding revealed a modest but significant correlation between DNA damage and job seniority. Conclusion: The study highlights the intricate relationship between occupational exposure to gasoline components, DNA damage, and work shift lengths. Extended shifts correlate with heightened genotoxic effects, emphasizing the importance of personalized safety measures. The significant correlation between DNA damage and job seniority introduces occupational longevity as a determinant in the genetic health of gasoline station attendants. This discovery has implications for implementing targeted interventions and preventive strategies to safeguard workers' genetic integrity throughout their years of service. The study calls for further exploration of unconsidered factors in understanding the multifactorial nature of DNA damage in this occupational setting.

Low pathogenic avian influenza (LPAI; H9N2) and Newcastle disease (ND) are economically important poultry diseases in Korea. In this study, we investigated pathological features and virus distribution in the lymphoid tissues of chicks experimentally infected with H9N2 and/or ND virus. Six-weeks-old SPF chickens were divided into 4 groups, Control (C), H9N2 (E1), NDV (E2), and H9N2+NDV (E3). E1 group was challenged with 0.1 ml A/Kr/Ck/01310/01 (H9N2) $10^{5.6}$ $EID_{50}$ intranasally, E2 group was challenged with 0.5 ml KJW (NDV) $10^{5.0}{\sim}10^{6.0}$ $ELD_{50}$ intramuscularly, and E3 group was challenged with H9N2, followed 7 days later by NDV. In histopathological examination, E1 group showed depletion and necrosis in bursa of Fabricius, thymus, cecal tonsil, and spleen, whereas E2 and E3 groups were noted severe lymphocyte depletion and necrosis with destruction of lymphoid organs structures. In TUNEL assay, apoptotic bodies were detected in lymphoid organs of all experimental groups, which was most severe in E3 group. H9N2 and ND viruses were predominantly detected in cecal tonsil of E1, E2, and E3 groups by PCR and immunohistochemistry (ICH). In conclusion, co-infection of H9N2 with NDV caused severe pathologic lesions and apoptosis in lymphoid tissues compared to single infections.

Purpose: The purpose of this study was to seek ways to improve the quality of life of workers by separating workers into the low fatigue group and the severe fatigue group depending on the level of fatigue level, and analyzing and understanding the difference between quality of life and job stress according to the fatigue level. Methods: For the 'Development of Mibyeong management system which was a consumer-directed health care service', the data of job stress, fatigue and quality of life was collected from 115 workers who visited the oriental hospitals located in J city and C city from Jul, 2012 to Dec, 2012. Results: The severe fatigue group showed significantly higher job stress than the low fatigue group in physical environment (p=.004), job demand (p<.001), interpersonal conflict (p=.012), lack of reward (p=.062). The severe fatigue group showed lower degrees both in physical component summary (PCS) (p<.001) and mental component summary (MCS) (p<.001) measured by SF-12 and the quality of life (p<.001) measured by EQ5D than the lower fatigue group. A relatively strong negative correlation was found in the item of mental component summary (MCS) measured by SF-12. Conclusion: Considering our results that high fatigue level show negative impact on quality of life and job stress, we suggest to provide a variety of health promotion strategies to improve the quality of life through the prevention and relief of fatigue for workers.
