By whom and when the paperfuge was invented (20521 김하정) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1816015363 In 2017, A surprising invention appeared in the world. It was paperfuge, a very simple centryfuge (a machine that seperates blood sells from plasma by spinning fast) made of only a string and some paper. Professor Manu Prakash was the inventor of paperfuge. ]]> 2021-10-14 04:45:33 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1816015363 2.How it Got started(20532 한민재) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1816015775 In 2013, Professor Manu Prakash visited the Uganda Clinic for research. He then saw that the centrifuge, a medical device capable of identifying malaria infection left unattended. He was told by local medical staff that the device was left unattended because there was no electricity here and there was no money to maintain the equipment.The shocked professor then began to develop cheap centrifuges.He studied many toys but failed. One day,He recalled his childhood in his dream. and He recalled a top made of thread and paper that he played with when he was young.He got an idea from his dream and made a paper fuse.]]> 2021-10-14 04:45:48 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1816015775 The Meaning of Appropriate Technology (20521 김하정) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1822787713 Appropriate Technology : 적정기술 💡

Appropriate technology means technology which is appropriate for user, even if it is not a cutting-edge technology. What is important in appropriate technology is the use of renewable sources, for example, energy from the sun.

This is typically done by spinning the sample at an extremely fast rate in a device called a centrifuge. Once the strings are completely unwound, they start to rewind, forming a super-coiled structure. The repeated winding and unwinding of the string spins the disks super fast, allowing to separate blood from plasma in a short period of time. And that makes it possible to diagnose malaria.]]> 2021-10-18 01:18:34 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1822790728 My Opinion: The Reason You Think the Technology Is Important(20532 한민재) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1822798949 I knew for the first time about paper fuses. When I first saw this, I thought it was just a toy. However, during the investigation, I watched the professor's interview video, and when I saw the video, I thought it was amazing that the professor made a paper fuse.Also I was surprised that this paper fuse can separate malaria faster than conventional centrifuges.I think this paper fuse is important because 200 won can quickly separate malaria without electricity, which helps people living in places where electricity cannot be supplied.]]> 2021-10-18 01:22:16 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1822798949 My Opinion: The Reason You Think the Technology Is Important (20521 김하정) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1839353078 Every year, millions of people die because of Malaria. Malaria is an infectious disease which is transferred by mosquitoes. To figure out someone if is stricken with Malaria or not, we must check blood cells, because Plasmodium (a Malaria protozoa) is seen at the blood cells. We need one more step before finding Plasmodiums; separating bloodcells from Plasma. Paperfuge does that. By spinning 125,000 times per minute, it can do what we had to do with a big, complex machine that uses a lot of electricity.
This is why paperfuge is an amazing invention. With this, we can not only reduce the use of electricity, but also enable Malaria examinations in developing country where people can't get high medical welfare.]]> 2021-10-24 14:34:57 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1839353078 My opinion: Why I think this technology is important (20512 장주혁) https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1839470301 In developing countries, many people still die from malaria. It is because such countries do not have the technology and money to diagnose malaria. However, the invention of a professor changed the situation they faced. At a low price Malaria can be easily diagnosed, and fast treatment have been possible even if they are infected to malaria. Those who have no skills and poor social weaknesses are the ones we need to protect. And the invention of papefuge helped the person who need help the most. ]]> 2021-10-24 15:42:35 UTC https://padlet.com/LEEDONGHU/lxeinehcdzhqhzke1645023654/wish/1839470301
