Introduction
A comparison of the Technology of Goryeo and Foreign Countries
Motives for doing research
Through the study of hidden technology from the Goryeo Dynasty that many people do not know about, by comparing the characteristics of the cannons and metal types of the Goryeo Dynasty with those of foreign cannons and metal types, we explained the excellence of the technology of the Goryeo Dynasty. As a student at Ganghwa Girls ' High School in Ganghwa Island, which was the capital of Goryeo, we wanted to accumulate diverse knowledge about the Goryeo Dynasty. As of 2018, the research was conducted to mark the 1100th anniversary of the founding of the Goryeo.
Background knowledge
What is a cannon(Chongtong gun)?
- A type of weapon used to fire arrows from the Goryeo Dynasty.
- The chongtong gun is a cannon ball of the Joseon Dynasty. The names were divided according to the size, weight of gunpowder, the number of bullets, and the distance to which they were used, according to the order of 천자문(千子文) was separated by 천(天)·지(地)·현(玄)·황(黃)
- A cannon is a large, uncarrying weapon with a large firing range and a greater range than the gun.
Since the introduction of artillery in Europe in the middle of the 14th century, main steel shells replaced stone at the end of the 15th century, At the same time, in France, a new lighter a cannon cast in bronze was placed on a horse-drawn motorcycle carriage, which led to the emergence of field guns. The new mobile French field gun has introduced the concept of a trunnion, making it easier for guns to be placed on permanent cartwheels, allowing for relatively accurate aim and range expansion.
The origin of the invention of metal types
It was designed to make up for the fact that it is difficult to preserve woodblocks for a long time and to break them easily.
Middle Ages
European and Chinese cannon
The cannon of the Goryeo Dynasty
German metal movable types
The metal movable types from the Goryeo Dynasty
○ Process for making metal types in the Goryeo Dynasty
1. It is carved into the wax one by one letter to form 어미자.
2. Wrap the wax and then form a mold.
3. Pour molten iron from copper, tin, and lead into a mold.
4. Remove and polish metal types made from molten iron.
5. Arrange the types according to what you want to print.
6. Put ink on the type face and paper over it.
○ The character of metal type
It was made of metal so it could be stored for a long time.
It was able to print different kinds of books by combining type with metal letters.

Modern times
Modern technology
3D Printer
Today, a three-dimensional printer(3D - printer) has been created combining traditional printing technology with the wisdom of our ancestors. Three-dimensional printing is a manufacturing technique that produces three-dimensional objects by spraying a continuous layer of matter. By using this, they were able to create objects in three dimensions, not in two dimensions. [2]
Missiles
The rocket weapons, including cannon, have at present developed into missiles. A missile is a generic term for a weapon that is driven by a rocket, jet engine, etc. and is guided until the target is reached at the point of induction. A missiles don't just shoot at targets like shells and fly away.also it's got an induction device inside it After it's launched, it measures its speed and direction. Missiles have the ability to hit the target by as amended it. [3] [4] [5]

why did I join this camp(expectations) I thought how efficient it would be to write 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. why did I choose this topic 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, we will learn more. what did I learn until now 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. what did I learn until now The shooting sight of the cannon fills the medicine barrel of the cannon, inserts the back of the arrow through the gun, lights the signal line, and burns off the powder of the gun. The explosive force produces an arrow that is inserted into the barrel. 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. 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 armed forces. If Mongolia's gunpowder weapons were used in the Jindo battle, they should be considered to have been used in the next attack on the South Korean military on Jeju Island. 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. The use of gunpowder in Jindo Island and in the fight on Jeju Island is suspected, even when the Korean military invaded Japan at a time of only one year or years. And records such as " The fire and the attack on Jeju Island caused the enemy to fall down in surprise, " may also be related to the use of gunpowder. my role By comparing the guns of Goryeo and other countries, we look for things to complement and complement our own creativity and find out the physical principles that are used in the cannon what do expect from this forum We 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. " He also worked with his friends, told them things he could not understand, came up with ideas, and developed a sense of cooperation in his role.

The reason why I joined the global camp is because I wanted to improve my English and spend my vacation in good condition. Actually, I thought about participating in a global camp because it is a short vacation, but I got to participate this time because I don't join it when I was in the first grade. During this camp, I will be able to learn a little bit about the technology of Goryeo and get a sense of achievement when I finish and present my assignments in three days. And the reason why our group chose Goryeo's science and technology as the topic was because we wanted to find the physical principles contained in it by getting to know its science and technology. Also, what he knew about cannon among Goryeo's scientific technologies was that it was made by the principal of action and reaction. However even so I did not know much about the cannon but when I investigated it, I realized that it was a rocket weapon. Also my role is to investigate a missile which is the current weapon involved in cannon and make ppt. Through this camp, I think I can gain patience with effort to study English with my poor English skills and our group can develop cooperative attitude by working together and completing one task.
