Due to the various toxic chemicals, accidents and job stress, the firefighter has been known as a dangerous job. However, in Korea, there is no proper system to improve their health or job fitness. The authors tried to look into the current state of occupational health problems of firefighters and to suggest some important points to improve their health and fitness for work. The injury incidence of firefighters was higher than that of other jobs and their life expectancy was shorter than any other public servants. Even though the health examination for firefighters was applied since 2004, there is no appropriate approach to examine the health and to assess the fitness for firefighting work. A standardized periodic special health examination based on their work conditions or health risks, for instance various chemicals, physical factors and psychosocial factors, is needed. We suggest that the other health examination system that firefighters can take a specialized health examination in case of uncommon situation to be a risk on health. In addition, the fitness test for injured or ill workers is necessary. As a conclusion, the comprehensive occupational health management system is necessary to make firefighters healthy and for the citizens' safety.

BACKGROUND: The aims of the study are to investigate the present state of occupational health management (OHM) in small enterprises, to explore the related factors, and to provide the information for effective policy of OHM in those enterprises. METHODS: The study subjects were 155 small enterprises that had referred the measurement of workplace hazards to a hospital at the East Seoul, Korea. Self-administered questionnaire survey was conducted by Fax. The contents of the survey were present state of OHM and related factors. RESULTS: 1. The characteristics of OHM in charge were as follows; among the health manager (1) 81.9% had the high authority, (2) 63.2% could explain workplace hazard, (3) 52.9% had outside professional education, (4) 49.7% recognized the need for occupational health, and (5) 67.7% had pragmatic perspective on workers' health protection. 2. The occupational health activities that showed higher performance rate were as follows; periodic health examination (86.5%), measurement of workplace hazard (92.9%). The occupational health activities that showed lower performance rate were as follows; appointment of emergency hospital (26.5%), replacement health examination (18.1%), health education (30.0%), health promotion (23.3%), preparation of health statistics (14.8%), planning health management (9.7%) 3. As results of multiple logistic regression analysis, the factors associated with the higher activity of occupational health were longer duration(more than 5 years) of health manager in charge(OR=2.41), pragmatic perspective on workers' health protection (OR=3.79), experience of outside professional education (OR=2.40), repair of automobiles(OR=3.31), workplace that employed more than 10 workers (OR=4.02), history of workers' compensation (OR=8.05), employers' high concern (OR=4.61). CONCLUSION: These results suggest that interest of employers and appointment of suitable health manager in charge were important, and minimum regulations and the development of occupational health program integrated with promoting productivity are required to activate occupational health in small enterprise

BACKGROUND: The aims of the study are to evaluate the effectiveness of a workplace smoking cessation program, and to investigate the role of the occupational characteristics for planning better smoking cessation program (SCP). METHOD: 258 workers' smoking statuses were surveyed. A follow up survey was conducted after 6 Month SCP including campaign, health education, provision of nicotine patches, and smoking cessation incentives. Theup rate was 89.2%. RESULTS: 1. Thesmoking rate was reduced from 67.4% (before SCP) to 45.3 %. The rates after SCP were different by the type of job and the status of employment. The participation rate of the office workers was 32.8%, and that of the technician was 55.6% (p<0.01). The rate of the regular workers was 59.4%, and that of the irregular workers was 36.8% (p<0.05). 2. Among of 174 smokers, 55.9% participated in SCP. According to the type of job and the job position, the participation rate was different. The rate of office workers was 69.9%, and that of the technician was 47.5% (p<0.01). Among the managerial personnel 86.4% participated in SCP, and amongthe plain workers, 52.5% (p<0.01). 3. In multivariate analysis, the smoking cessation rate was higher in office workers (OR=3.21), the group of lower job demand (OR=3.12), that of absence of family stress (OR=2.91), and that of lower perceived stress (OR=3.51). CONCLUSION: The SCP based on social-cognitive theory reduced smoking rate, but increased the difference of the smoking rates by the type of the job. These results suggest that the SCP using social-context model is important to establish the better strategy to stop the smokin

There has recently been increased publicity on the risk of venous thrombosis after long-haul flights. This paper reviews the evidence related to the association between air travel, especially long-haul and venous thromboembolism (VTE). The evidence consists only of case reports, clinical case-control studies and observational studies, but with few study of Korean population. Some studies have suggested that there is no clear association, whereas others have indicated a strong relationship. However, the overall association between air travel and VTE is likely to be weak, mainly affecting passengers with additional risk factors for VTE. The available evidence may not be adequate to estimate the risk. Further well-desiged case-control studies are urgently needed in order to identify the risk factors related air travel.

The respiratory system is one of the most important body systems particularly from the viewpoint of occupational medicine because it is the major route of occupational exposure. In 2013, there were significant changes in the specific criteria for the recognition of occupational diseases, which were established by the Enforcement Decree of the Industrial Accident Compensation Insurance Act (IACIA). In this article, the authors deal with the former criteria, implications of the revision, and changes in the specific criteria in Korea by focusing on the 2013 amendment to the IACIA. Before the 2013 amendment to the IACIA, occupational respiratory disease was not a category because the previous criteria were based on specific hazardous agents and their health effects. Workers as well as clinicians were not familiar with the agent-based criteria. To improve these criteria, a system-based structure was added. Through these changes, in the current criteria, 33 types of agents and 11 types of respiratory diseases are listed under diseases of the respiratory system. In the current criteria, there are no concrete guidelines for evaluating work-relatedness, such as estimating the exposure level, latent period, and detailed examination methods. The results of further studies can support the formulation of detailed criteria.

The range of diseases covered by workers' compensation is constantly expanding. However, new regulations are required for the recognition of occupational diseases (ODs) because OD types evolve with changes in industrial structures and working conditions. OD criteria are usually based on medical relevance, but they vary depending on the social security system and laws of each country. In addition, the proposed range and extent of work-relatedness vary depending on the socio-economic conditions of each country. The Labor Standards Act (LSA) and the Industrial Accident Compensation Insurance Act (IACIA) of Korea employ lists based on their requirements without listing causes and diseases separately. Despite a considerable reshuffle in 2003, the basic framework has been maintained for 50 yr, and many cases do not fit into the international disease classification system. Since July 1, 2013, Korea has expanded the range of occupational accidents to include occupational cancers and has implemented revised LSA and IACIA enforcement decrees. There have been improvements to OD recognition standards with the inclusion of additional or modified criteria, a revised and improved classification scheme for risk factors and ODs, and so on.

OBJECTIVES: Noise-induced hearing lose(NIHL) is characterized by bilaterally symmetrical hearing loss, but some screening audiometries of employees who were exposed noise showed asymmetry. Therefore, this study was carried out to evaluate distribution of asymmetrical hearing loss and factors influencing asymmetries. METHODS: Study subjects were 294 male employees who have participated in 1st and 2nd noise-specific health examination. RESULTS: The interaural threshold difference of 20 dB or more at 4,000 Hz was classified as asymmetry. Among 294 NIHL employees. 19% had left asymmetric hearing loss. 22% had right asymmetric hearing loss. and overall asymmetry were 41%. Prevalence of asymmetry at 4,000 Hz significantly more decreased in middle(80~84 dB (A)) and high-level noise exposure groups(> or =85 dB(A)) than low-level exposure group and significantly increased as greater hearing threshold level in the worse ear. Prevalence of left asymmetry at 4,000 Hz significantly increased as greater hearing threshold level in the worse ear than right asymmetry. The interaural difference was significantly greater in the left asymmetry. CONCLUSIONS: Noise exposure produced asymmetric hearing loss(interaural asymmetry was 20 dB and more in 41% of case) and left ear was more susceptible to noise demage than right ear.

BACKGROUND: The South Korean criteria for occupational diseases were amended in July 2013. These criteria included formaldehyde as a newly defined occupational carcinogen, based on cases of “leukemia or nasopharyngeal cancer caused by formaldehyde exposure”. This inclusion was based on the Internal Agency for Research on Cancer classification, which classified formaldehyde as definite human carcinogen for nasopharyngeal cancer in 2004 and leukemia in 2012. METHODS: We reviewed reports regarding the causal relationship between occupational exposure to formaldehyde in Korea and the development of these cancers, in order to determine whether these cases were work-related. RESULTS: Previous reports regarding excess mortality from nasopharyngeal cancer caused by formaldehyde exposure seemed to be influenced by excess mortality from a single plant. The recent meta-risk for nasopharyngeal cancer was significantly increased in case-control studies, but was null for cohort studies (excluding unexplained clusters of nasopharyngeal cancers). A recent analysis of the largest industrial cohort revealed elevated risks of both leukemia and Hodgkin lymphoma at the peak formaldehyde exposure, and both cancers exhibited significant dose-response relationships. A nested case-control study of embalmers revealed that mortality from myeloid leukemia increased significantly with increasing numbers of embalms and with increasing formaldehyde exposure. The recent meta-risks for all leukemia and myeloid leukemia increased significantly. In South Korea, a few cases were considered occupational cancers as a result of mixed exposures to various chemicals (e.g., benzene), although no cases were compensated for formaldehyde exposure. The peak formaldehyde exposure levels in Korea were 2.70–14.8 ppm in a small number of specialized studies, which considered anatomy students, endoscopy employees who handled biopsy specimens, and manufacturing workers who were exposed to high temperatures. CONCLUSION: Additional evidence is needed to confirm the relationship between formaldehyde exposure and nasopharyngeal cancer. All lymphohematopoietic malignancies, including leukemia, should be considered in cases with occupational formaldehyde exposure.
