Welders working in a confined space, like in the shipbuilding industry, are at risk of being exposed to high concentrations of welding fumes and developing pneumoconiosis or other welding-fume exposure related diseases. Among such diseases, manganism resulting from welding-fume exposure remains a controversial issue, as the movement of manganese into specific brain regions has not been clearly established.(omitted)

Objectives: To assess the hazard of Korea chrysotile and anthophylite, fibers were analyzed for their physicochemical properties by transmission electron microscope equipped with energy dispersive X-ray spectrometer (TEM-EDS). Methods: To evaluate the biopersistence of 2 domestic asbestos, Sprague-Dawely rats were exposed to 2 mg asbestos by intratracheal instillation. Each asbestos (chrysotile ; $8,814,244{\times}10^6$ fibers/mg, average size $0.08{\mu}m{\times}4.39{\mu}m$, anthophyllite ; $5,182{\times}10^6$ fibers/mg, average size $0.95{\mu}m{\times}7.29{\mu}m$) were evaluated after a single intratracheal instillation. At times from 1 week to 4 weeks after exposure, the numbers of asbestos fivers in the bronchoalveolar lavage fluid and in the lung were calculated. Results: Anthophyllite fivers continuously have retained for 4 weeks but chrysotile fivers were rarely found at 4 weeks after exposure in the bronchoalveolar lavage fluid. Chrysotile fivers at 4 weeks after treatment were not observed but anthophyllite was easily observed in the lung with phase contrast microscopy. According to electron microscopic observation of asbestos in the lung, within 1 week after the administration of chrysotile fivers were decreased rapidly but anthophyllite fivers were very little change for 4 weeks. When chrysotile fivers have been lost Fe in 1 week, there were no significant changes in anthophyllite fivers in the lung. Conclusions: These findings indicate that after a long time exposure to chrysotile, asbestos bodies can not be found in the bronchoalveolar lavage fluid.

Health information technology (HIT) is one of the most familiar tools to healthcare providers. It is used in routine practice to reduce cost, to improve clinical performance, and to improve patient safety. Patient safety is the driving force of recent expansion of HIT industry. But there are many evidences that it can be harmful to patient safety. Role of HIT and HIT-related error became big issues because more and more healthcare providers and healthcare organizations are willing to adopt it. Adoption rate of HIT in Korea is higher than that of United States. But researches of HIT regarding patient safety are rare. In this article, types of HIT, their mechanisms of improving patient safety and HIT-related errors were reviewed. Status of HIT in terms of patient safety in Korea was also reviewed. Knowledge of how HIT can improve patient safety, its' limitation, and how to make it safer is crucial to whom have to use it to improve patient safety. Impact of HIT on patient safety must be evaluated actively in Korea. HIT which was proven to improve patient safety must be widely adopted. Government must prepare a strategic plan to improve HIT quality, support hospitals financially and institutionally to introduce qualified HIT, and develop HIT infrastructures and standard designed for patient safety.

Background: According to the US Bureau of Labor Statistics, musculoskeletal disorders (MSDs) accounted for 32% of all nonfatal injury and illness cases in 2014 among full-time workers. Our objective was to review and summarize the evidence linking occupational exposures to vibration and awkward posture with MSDs of the shoulder and neck. Methods: A literature search was conducted using the terms musculoskeletal disorders, vibration, and awkward posture. All types of observational epidemiologic studies, with the exception of case reports, published during 1998-2015 were included. Databases searched were MEDLINE (Ovid), Embase (Ovid), Scopus, Ergonomic Abstracts, NIOSHTIC-2, and Health and Safety Science Abstracts. Results: Occupational exposures to whole-body or hand-arm vibration were significantly associated with or resulted in MSDs of the shoulder and neck. Awkward postures while working were also associated with MSDs in these locations. These findings were consistent across study designs, populations, and countries. Conclusion: Occupational exposure to vibration and awkward posture are associated with shoulder and neck MSDs. Longitudinal studies are required to elucidate the mechanisms responsible for these associations, and intervention studies are warranted.

The purpose of this case study is to report a case of lung cancer with exposure to welding fumes of welders in Korea and to demonstrate the causal relationship with exposure to welding fumes, especially with nickel and hexavalent chromium. The case is 47 years old, and had been engaged in welding, gas cutting, grinding and gousing on mild, stainless steel and nickel steel for 11 years from 1982 to 1993, and have been engaged in cleaning steel rollers with a cleaning oil in the same work shop since 1993. The level of welding fume exceeded the occupational exposure limit of $5mg/m^3$ established by the Korean Ministry of Labor and American Conference of Government Industrial Hygienists (ACGIH). Especially, detectable hexavalent chromium and nickel was generated during welding, gousing on stainless and nickel steel. However, there was no ventilation systems(local and dilution) and no personal protection. There is several evidence that the past (1983-1993) exposure would be higher than the present. In conclusion, the lung case could be associated with his task including welding, gousing, and this association could be attributed to carcinogenic potential of the nickel and chromium in the fume.

Purpose : This study is to supply basal data need to development of First-Aid education program for female college students of non-health department that we surveyed safety awareness practice, First-Aid knowledge, educational requirement and necessity of the female college students of health and non-health department. Methods : This date was collected from September 1th in 2012 until October 5th by 5 person selected of which explain to purpose and method of the writing. We distributed the subject questionnaire of total 410 and analyzed questionnaire 385 only. Results : The results of this study are follows. First, the health group was higher than non-health group in conductive score of safety awareness and score of First-Aid knowledge in female students and there was statistically significant difference. Second, There was significant difference in Economical state, Educational state of the Safety awareness Practice score and First-Aid knowledge score about the general characteristic of the female college students of health department. Third, there wasn't significant difference in most of all item of the Safety awareness Practice score and First-Aid knowledge score about the general characteristic of the female college students of non-health department. Conclusion : Finally, We found that the female college students of health department lower than the female college students of non-health department in First-Aid knowledge level and surveyed that they felt the needs of First-Aid education. Therefore, there are able to need the opening of a course in order to raise the quality of safety awareness and First-Aid knowledge or to needs construction of educational system in continuously.
