I thought how efficient it would be to use things that I learned while studying English. Also, I wanted to experience various cultures and broaden my thinking by talking with foreigners outside my country. So, through this global camp, I wanted to experience various cultures by reducing the burden of speaking English and talking about daily life freely and comfortably. And I wanted to let foreigners know this topic 'Goryeo' because it was a very valuable history and it contained a lot of value. Therefore, as a proud Korean citizen of our country, I hope our country will be recognized from abroad. Through this global camp, I will talk about a topic with foreigners, experience a variety of ideas, and have a more open mind. We will also work with our team members to prepare for the presentation, fulfill our roles responsibly and learn how to collaborate efficiently through the Media Wiki. And we will be able to make our results visible to anyone, thus making our nation more valuable. In fact, I am more interested in science than in history. But I wanted to take this opportunity to explore the convergence of history and science. There is much that can be gained from past technology. If you look at the inventions of the past and see why they were invented, and how they influenced our ancestors ' lives, if you apply them to the present era, you will be inspired to think about ways to think about them. There are many inventions that can see wisdom of our ancestors in our country. And most famous of all, during the Goryeo Dynasty, metal types and cannon were used. But I wanted to explore more because I didn't know the exact details of the scientific principles and the background. Also, since it is a global camp, if we compare it with other countries and find out what our inventions have and should complement, I will learn more. what I already know about this topic is that Metal types were invented in Korea during the Goryeo Dynasty, before Germany. Print a combination of metal types. The first book to be made with these metal types was Jikji. cannon was first developed by Choi Moo-seon in Korea during the Goryeo Dynasty. cannon was the first to develop in China, but thanks to Choi Moo-seon's development of the cannon, Goryeo was able to resist Japanese invasion. In addition, they set up a " hwatul dictionary " to promote the development of cannon. Choi Moo-seon also made the nation's first rocket, ' Juhwa ', which means ' Running Fire’, "Juhwa " refers to putting gunpowder into a paper container made by rolling it, and the powder inside the paper barrel burns, and the combustion gases are blown back by force. Although none of the gunpowder manufactured by Choi Moo-seon can be confirmed on the scale and structure of the weapons, it is certain that they are the foundation of the nation's gunpowder weapons. Choi Moo-sun's contribution to the nation through the development of gunpowder and gunpowder weapons is beyond comparison with anyone's achievements. What I learned additionally from the investigation is Mongolia's use of gunpowder. From a military perspective, it was important for the Mongolian military to prepare for an attack based on abundant intelligence, but the Mongolian military introduced a gunpowder weapon that was just being used in combat. Mongolia's use of gunpowder was noted as an important issue that dealt a decisive blow to the Sambyeolcho. After the armed forces were completely crushed in Jeju Island in 1273, Mongolia began to fight against the Japanese government in 1274. In this fight, a new weapon used by the Japanese army, which attracts attention. And records such as " The fire and the attack on Jeju Island caused the Sambyeolcho to fall down in surprise, " may also be related to the use of gunpowder. By comparing the guns of Goryeo and other countries, I look for things to complement and complement our own creativity and find out the physical principles that are used in the cannon. I could examine and compare not only the cannon of Goryeo but also other countries. I do not think our country is better unconditionally and I have a position to respect each characteristic. Through these various investigations, we can have an open mind to prepare for the global era. Also I could see wisdom by looking at various inventions from the Goryeo Dynasty and have developed pride in our country. I will become a person who helps our country by building more knowledge and creativity. I studied with my friends, told things which could not understand each other, came up with ideas, and developed a sense of cooperation in my role.
