※ This video is part of <Extreme Job - Overcome the bitter cold of midwinter! Industrial divers and casting, siraegi deokjang> broadcast on January 10, 2024. MacGyver under the sea, industrial divers! Industrial divers appeared at the yacht pilot license examination center in Geoje-si, Gyeongnam. They are there to remove foreign substances such as barnacles and seaweed from the bottom of the yacht. If foreign substances stick to not only yachts but also ships, friction increases, reducing sailing speed and increasing fuel consumption, so regular cleaning work is necessary. In order to clean the bottom of the yacht, you have to dive and use water pressure in the seawater to remove foreign substances. It is said that working under the sea in the cold winter is not only physically exhausting, but also makes even divers with over 10 years of experience nervous all the time due to the unpredictable sea environment. Underwater work is done in shifts of 1 hour each for the safety of the divers. After cleaning the bottom of the yacht, divers begin to remove the steel structures installed at the dock. It is a dangerous job that requires cutting rebar using welding equipment underwater, so it must be done by experienced divers. Since it is underwater where one mistake can threaten one’s life, one must always be on edge while working, but since it is not a job that anyone can do, they say they work with pride. In Yanggu, Gangwon-do, covered in snow, where the cold of winter is welcome, the work of collecting dried shiitake mushrooms that were spread out in early winter is in full swing. Dried shiitake mushrooms, which are naturally dried by repeating freezing and thawing in the cold winter of -20 degrees Celsius, can easily break, so this should only be done on cloudy or snowy days. It takes 20 kg of dried shiitake mushrooms to harvest 1 kg of dried shiitake mushrooms. The harvested shiitake mushrooms are boiled in hot water and then hand-washed to remove foreign substances such as sand, and this process has to be repeated in cold water until they are clean. After the washing process, the dried shiitake mushrooms are individually picked out of damaged leaves and cotyledons, and then packaged according to the quantity. ✔ Program name: Extreme Job - Beat the bitter cold of midwinter!
