Before joining the global issue forum camp for the first time, I didn't know exactly what it was and thought it would be difficult. But I thought that I can learn something even though it's difficult. Also, I participated with the idea that ‘ Will this opportunity come again?’ and ‘Let's take this opportunity to improve my English skills.’ It was a difficult subject for me because as I have never studied it I don't have enough information. But the kind and detailed explanations of the native English teachers and professor Kim Hyun's explanation touched me so deeply that I did not doze but listened very carefully.
The reason why we chose the subject of ' Comparing the Science and Technology of the Goryeo' is because, in our opinion, we are capable not only make some scientific research about it but also we are able to compare the characteristics of Goryeo's cannons and metal types with those of other countries. We thought that it would be a great opportunity to explain the excellence of the technology of the Goryeo Dynasty. Moreover through comparison with foreign products we wanted to find the excellence and security of our one. And, finally, as we are in Ganghwa, the capital of Goryeo, it is a good opportunity for us to build various knowledge of Goryeo.
Our team divided science technology into cannon and metal types. The cannon was invented in the Goryeo Dynasty by Choi Moo Sun(崔茂宣). The challenge was to find out the physical characteristics of the cannons and find out their varieties. Regarding the metal type of Goryeo Dynasty, we have to find out what characteristics were used and the same compared to the metal type from Germany. I have never explored these two subjects in depth before, and the only thing I know is that Goryeo's metal types were ahead of Germany. Although it was hard to explore a topic having lack of background knowledge, I felt myself very proud and growing.
My role in our group was to organize material that were found by our team into ppt presentation. I also took part in searching information about how printing technology has developed in modern times.
I learned a lot from making presentations by simply compressing and organizing the materials and using the Media Wiki to do simple coding. Now I know that there is a typical 3D printer in modern printing and nowadays we have a cutting edge in printing ideas as well as text messages. While searching for data, I also saw a lot of information about metal types from Goryeo. The document that was printed in metal type is Jikji. The metal type was made of brass. The reason for this is that the brass is satisfy the characteristics of easy melting, strong enough and free from ink damage. Also, people in Goryeo used metal types, korean paper (hanji) and ink named Yoo Yeon Mook(油煙墨) for making jikji. Yoo Yeon Mook(油煙墨) ink was made of a mixture of soot, glue, and such as paulownia oil or redwood oil that is well coated on a smooth metal surface. This unique characteristic of Korea met the optimum conditions for good use of metal types. The tenacity, passion and wisdom of our ancestors, who finished each type manually, seems to have contributed to making the modern printer.
Through this camp, I hope to improve my English skills by talking with native English teachers and writing reports in English. In future I hope to become an air controller. And, as you know, air traffic controllers need English, so I hope this camp will help me to achieve my goal. Also, I wish this camp will motivate me to be more interested in the history of Korea. Since our group subject is the science and technology of Goryeo, I hope it will be a camp where I can learn more about the history of science technology.
In conclusion, I want to say that I feel so proud that I am a student at Ganghwa girls’ high school, because our school is located in Ganghwa, which was the capital of Goryeo.
