Ganghwa Island has a lot of historic tourist attractions. and I have lived in Ganghwa Island for quite a while. Ganghwa Island, which was the capital of Goryeo has such a wide variety of relics so that it is called a " roofless museum. " Despite I have lived in Ganghwa island for a long time but many of the historic tourist attractions what I see on my way to school or academy were not very inspiring to me. Also, even when my relative sister came to Ganghwa Island for a school excursion, I though “is there any reason to visit to Ganghwa island for excursion?” so I participated in this camp because I wanted to know more about Ganghwa Island and Goryeo that I mostly ignored them. and also to achieve my interesting in Goryeo. In fact, I think many people know about scientific technology about Joseon, But if you ask questions about the technology of the Goryeo Dynasty to them most people will not be able to answer it. This is because there are not many relics from the Goryeo Dynasty in South Korea, and books also rarely come down. Most of the relics of the Goryeo Dynasty that remain on the Korean Peninsula exist in North Korea. So I hope that through my quest, many people will be interested and excited. about the technology that we did not know about during the Goryeo Dynasty.
so I'm going to have to do looking for scientific excellence in the cannons and metal types of Goryeo Dynasty. and learn about the technology that protected the nation with cannons and metal types that helped people to promote their knowledge. In plain words, The metal type of Goryeo Dynasty was made of metal. After combining metal types and If you dip it in ink, you can easily create multiple books. This is faster than writing in a hand, and also It is convenient because it does not wear out like wood type. However, advanced technology is needed to make metal types. Korea is the first country in the world to make metal types. It is already known worldwide that the history of Goryeo in the invention and use of metal types. Next, I would like to look at the topic of cannon what I usually focused on. A cannon is a weapon that fires an object using the explosive power of a gunpowder. In other words, It was used to protect nation from the war. Choi Mu-seon has learned how to make gunpowder from China. After that the cannons were developed. Various gunpowder weapons made by the Choi Moo-seon can be divided into launchers, firings, bombs and rocket-type firearms. The results were most valuable in the battle against Japanese troops in August 1380. The Japanese were completely wiped out by Lee Seong-gye, a three-degree Chief Border Inspector who was ordered to Goryeo royal court. As you can see from these typical battles, it was a battle using the best gunpowder and weapons. The oldest cannon known in Korea is the chongtong of Kyunghee, which is presumed to have been made from the end of the Goryeo Dynasty to the early Joseon period at the latest, at least before King Sejong's reign. Kyunghee tubed firearm (chongtong) have the same shape as Sweden's Rochelt cannon and China's 14th century cannon of internal structure. However, the internal structure of our own cannon in the end of Sejong, Kyung Hee tubed firearm looks similar to the early Chinese tubed firearm. Considering that the size of the tubed firearm(chongtong), the chinese one was 300mm to 400 mm, it is 70 mm larger than the Kyung Hee tubed firearm(chongtong). so It is believed that tubed firearm was either created by Choi Moo-seon at the end of the Goryeo Dynasty or before the end of the King Sejong's reign. As can be seen from the metal types and cannons mentioned above.
During the Goryeo Dynasty, there were as many technological developments and foundations as there were during the Joseon Dynasty. In fact, in the course of such an investigation, I have had time to shame and reflect on my ignorance of Goryeo despite living in Ganghwa Island, which was the capital of Goryeo. In addition, we celebrated the 1100th anniversary of Goryeo, and discovered the science and technology of the Goryeo period, I got to know the science and technology of the Goryeo Dynasty. I put them on a media wiki, and I studied them with responsibility that people around the world would see them, so this activity was very meaningful to me. Not only that, but it was a memorable activity. Our wise ancestors, the hard inventions that the scientists of Goryeo made, are now shining with various scientific techniques. I think it's a good time to think again and show respect.
