      • 루뻬 미세수술에 있어서 등산용 헤드램프의 활용

        윤병민,한규남,김석화,Yun, Byung-Min,Han, Kyu-Nam,Kim, Suk-Wha 대한미세수술학회 2008 Archives of reconstructive microsurgery Vol.17 No.1

        Loupes-assisted microsurgery often needs an operational head lamp for a better condition of light. This may cause serious neck fatigue due to the weight the operational head lamp, the limitation of the operator's head movement from the hind cable, and some cost for purchasing and management of it. On the contrary, a mountain head lamp is very light, full of freedom in movement, applicable to all types of loupes, and relatively very cheap. In conclusion, a mountain head lame can be a cost-effective light source for Loupes-assisted microsurgery.

        이종한 ( Jong Han Lee ),이권섭 ( Kown Seob Lee ),박진우 ( Jin Woo Park ),한규남 ( Kyu Nam Han ) 한국산업위생학회 2011 한국산업보건학회지 Vol.21 No.3

        Objectives: It has been pointed out that there are problems in handling and managing chemicals due to trade secrets of Material Safety Data Sheet(MSDS). To date, some company intentionally leave out of several parts and use an inaccurate expression in MSDS. In particular, with the result of the inspection of the government and labour community, it is required that the 2nd section in MSDS included the composition and information on ingredients has to be provided with comprehensive expression to secure more reliability. Methods: Therefore, this study is aimed: 1) to recognize the current status of trade secrets of MSDS in workplaces with both domestic manufacturers of chemical products and multinational corporations; 2) to make contributions to prevention of the industrial accidents by providing the accurate information of MSDS; 3) to improve the risk communication system related with chemicals; 4) to impress workers on the importance of right of known for MSDS. With the result we analyzed the status of trade secrets in MSDS in 73 companies, such as petrochemistry production, paint production, metal processing oil production, detergent production, and international company related with chemicals, we have found that 38,150 (45.5%) have the trade secrets parts in the total number of 83,832 in MSDS. Also, based on the 288 MSDS gathered by the Occupational Safety and Health Research Institute (OSHRI) from 2005 to 2009, 41.7% of the MSDS are classified into the trade secrets. Conclusions: Therefore, to procure an assurance system of MSDS, we suggest that a MSDS picking up and checking system be legislated in the Occupational Safety and Health Act to protect workers from the unidentified chemical hazards due to the secret trade of MSDS.
