  • In South Korea, the enact of Korean Coast Guard Act-1 manages physical and chemical oil-dispersants. Oil snare, which is made of polypropylene, is newly added to the aforementioned act, and it has advantage on the ease of recovery compare to other adsorbents. This study synthesized bunker B-oil with diesel-oil and bunker C-oil to perform an adsorption test based on three samples which were manufactured in South Korea. As a result, adsorption test revealed 5.2 g/g more adsorption than the previous results from the act. Additional toluene test revealed that all the samples satisfied 90.0%, however coloured samples could release its pigment on the marine environment. Thus, colorless samples are recommended on the risk management of marine accidents. The study on the basic direction of the calculation of the test items and the standard value for the quality control of the oil snare was also carried out.

  • For Percutaneous control of the degree of constriction after pulmonary artery banding, we developed an adjustable banding device that was operated by oil pressure. This consists of a stainless steel snare, a polyethylene tube with silicone oil, and a screw adjuster. Five dogs underwent banding of the pulmonary artery or the descending aorta with this device. This band could be effectively and finely adjusted. Although these studies are preliminary, they suggest that a reversible pulmonary artery band can be performed.
