Respiratory effects in full time welders include bronchitis, airway irritation, lung function changes, and lung fibrosis. Welder's pneumoconiosis has been generally determined to be benign and not associated with respiratory symptoms based on the absence of pulmonary function abnormalities in welders with marked radiographic abnormalities.(omitted)

The ultimate goal of the quality control program for special periodic health examination agencies is to diagnose the health condition of a worker correctly, based on accurate examination and analysis skills, leading to protect the worker's health. The quality control program on three areas, chemical analysis for biological monitoring since 1995, and pneumoconiosis, audiometric testing since 1996, has contributed to improve the reliability of occupational health screenings by improving the issues including standardization of testing methods, tools, diagnostic opinions, and reliability of analysis for biological monitoring. It has contributed to improving the reliability of occupational health monitoring by rectifying the following issues associated with previous monitoring: absence of standardized testing methods, testing tools that are not upgraded, mismatching diagnostic opinions, and unreliable results of biological specimen analysis. Nevertheless, there are issues in need of further improvement such as lack of expertise or the use of inappropriate method for health examination, and passive and unwilling participation in the quality control. We suggested solutions to these problems for each area of quality control program. Above all, it is essential to provide active support for health examiners to develop their expertise, while encouraging all the health screening agencies, employers, and workers to develop the desire to improve the system and to maintain the relevance.

According to the epidemiological studies in chromium workers, hexavalent chromium is associated with the risk of lung cancer. Reactive oxygen species produced by hexavalent chromium exposure may play an important role in the carcinogenesis process. We measured one kind of oxidative DNA damages, 8-hydroxydeoxyguanosine (8-OHdG) and its repair activities as an indicators of cellular oxidative stress in rat lungs by the repeated inhalation exposure to sodium chromate.(omitted)

To investigate the genotoxic effect of 1, 1-dichloro-1-fluoroethane which was widely used as a cleaning solvent at the electronic part industry, the micronucleus frequencies were recorded by examining polychromatic erythrocytes in bone marrows of single i.p. injected mice at high doses and of the repeatedly inhaled rats for 13 weeks at relatively low concentrations.(omitted)

This study was conducted to identity the characteristics of occupational health and safety management systems around the world, to survey the implementation of OHSMS in Korean companies, to find problems and corrective measures, and to understand the opinions of top management about OHSMS. Questionnaires on the operation of occupational health and safety management systems in Korean manufacturing companies were carried out. Occupational health and safety management systems around the world, including OHSAS 18001, BS8800, KOSHA 18001, VPP, J-OHSMS, were reviewed. In order to implement an occupational health and safety management system successfully, it was found that the management should consider occupational health and safety as important, provide employees with necessary training, and have a strong commitment to occupational health and safety.

Objectives: The major objectives of this study are to review the requirements for the advancement of occupational safety and health administrative organization and to propose measures to establish an Occupational Safety and Health Executive. Methods: The problems of occupational safety and health administrative organization in korea were examined empirically and cases of occupational safety and health administrative organizations in developed countries were investigated (United Kingdom, United States, Germany, and Japan). A plan for establishing an Occupational Safety and Health Executive was proposed over the short and medium term. Results: An occupational safety and health administration is characterized by a professional and technical nature, and even more so in modern society. Therefore the greatest value required by an occupational safety and health administrative organization is expertise. In addition, administrative values it requires include efficiency, specificity, independence, and activity. The Korean occupational safety and health administrative organization has a number of problems in terms of these values. The most appropriate way to realize these values is to establish an Occupational Safety and Health Executive. It is desirable to establish such an Occupational Safety and Health Executive in a phased manner taking into consideration its relationship with Korea Occupational Safety and Health Agency(KOSHA), including KOSHA's functional adjustment Conclusions: In order to solve the deep-seated problems in occupational safety and health administrative organization and to advance occupational safety and health administration in Korea, it is necessary to establish an Occupational Safety and Health Executive as a foundation for achieving an advanced industrial safety and health administration.

This brief report aims to establish the keyword content of studies on occupational health and safety-the key framework of the world of work in the trade and health domain. Data were collected from the SCOPUS database, focusing on articles on occupational health and safety and related keywords, with an emphasis on abstracts and titles. Data were analyzed and summarized based on keywords included from the MeSH database. There were 24,499 manuscripts in the domain and 1,346 (5.40%) occupational health-related keywords, including those that overlapped. The most frequently referenced occupational health-related keyword was "occupational health" (452 articles), followed by "occupational safety" (141 articles). There were fewer keywords on occupational health in the trade and health literature. As the world of work has been prioritized because of the recent new normal of work life since the COVID-19 pandemic, examining the focus of occupational health priorities within the global perspective is crucial.

The alkaline single cell gel electrophoresis (comet) assay was used to clarify in vitro and in vivo genotoxicity of 2-bromopropane (2-BP). For in vitro studies, fresh medium containing 2-BP (2.50, 1.00, 0.50, 0.25, 0.10, 0.05, 0.01 mM, and vehicle control) were added in human lymphocytes.(omitted)
