HunMinJeongEum, meaning "the right sound to teach the people," was created in 1443 CE by King Sejong the Great, the fourth king of the Joseon Dynasty. In today's modern language, this letter, called Hangeul, is internationally recognized for its linguistic science. However, it is hard to find a comprehensive study on the fact that King Sejong himself created Hangeul, the Confucian perspective on natural disasters and democracy revealed in the process of writing, the independent efforts emphasized from a certain period, and the achievements of King Sejong, who shared the sorrow of the people and carried out national policies despite the extreme opposition of the nobility. Accordingly, I analyzed the consonants of HunMinJeongEum and looked at the essence of humanity and oriental philosophy (Yin-Yang Five Elements, Sangsu Philosophy, Hado). Surprisingly, different meanings from previous studies and interpretations were found, and King Sejong's "Da Vinci Code," which was left behind in the process of making the consonant, is reinterpreted and revealed. King Sejong's achievements were all connected as one. This is the root of democracy in the Republic of Korea today, and this is why King Sejong was selected as the most beloved and respected historical figure by the Korean people. This study will start with more people's understanding of the fundamental perception and philosophy of the world in Asia, including Korea, to reinterpret and reveal the hardships and great achievements experienced by a leader of a country in the process of creating korean alphabet, and to emphasize democracy, which is an important value for Asians and Westerners' mutual respect and co-prosperity.

Economic growth is one of the significant benchmarks determining a country's sustainable growth. Before WWII, most countries perceived their priority in terms of military strength as they dedicated most of their efforts and resources to creating weapons of mass destruction. The current research aims to establish some of the significant factors that may have contributed to the sustainable and progressive economic growth of South Korea within the 60-year timeframe. Multiple prior studies have attributed the economic growth in South Korea to policy reforms that opened the country to foreign markets. The outstanding increase in the percentage of exports stands out as an indication of the improvement in the quality of goods produced in the country. Finally, in recent years, China has dedicated more resources to research and developments as a strategy to improve innovation within the country and its overall economic growth. Other issues of concern likely to undermine the prospects of the country's economic growth include the limited geographical size, aging population, and limited natural resources. As such, South Korea needs to emphasize innovation and improve the business environment as its main strategy for sustainable economic growth in the future to maintain its continuous economic miracle.

Recently, as the status of South Korean popular culture has risen, the Korean Wave is gaining popularity not only in Asia but also in Europe, America, and South America, and is currently at the center of the global cultural phenomena. Among them, in particular, the cultural content industry has been developing rapidly thanks to the Korean Wave. Currently, the Korean Wave is spreading all over the world while bringing about positive effects to South Korea. In fact, until 2017, political and social issues such as 'North Korea/North Korean nuclear weapons' and 'Korean War' were considered as the images associated with South Korea, but from 2018, it has been shown that all images associated with South Korea are cultural content except for 'IT industry'. Given the economic effects that can be obtained not only from the positive associated images of South Korea per se but also from the complex action with various industries in South Korea, the craze for the Korean Wave can be viewed as affecting the overall national prestige of South Korea. For the steady vogue of the Korean Wave, thorough investigation of the Korean Wave and understanding of the expectations of consumers of the Korean Wave seem to be necessary

The purpose of this study is to discuss how Dongi People in ancient societies resided in the region including the Korean Peninsula shaped its economy, what kind of currency was used, and their economic activities using this currency. This study started from a skeptical point of view that the Dongi People were conducting economic activities with the currency used in the country made by the Jina People before and after the Gojoseon society. Currently, in China, all currencies issued in China are treated as their own currency. It is due to subjective interpretation from a nationalist point of view. Japan subjectively interprets and judges from a Japanese point of view and North Korea judges from the central point of view on the Korean Peninsula. This difference is due to the subjective interpretation from the researcher which has been affected by their associating academic area. This has caused the lack of objectivity. In other words, it means that there is a big difference in the perception of the interpretation of history between different academic areas. This study, therefore, tried to avoid the application of biased concept or academic research in order to define the distribution economics more objectively by conducting the study based on the literature sources from Chinese ancient books and field research materials as much as possible, as the study and research conducted based on the domestic sources are insufficient in the sense that there is a gap between different perceptions and interpretations. As a conclusion of this study, the excavation area of Myeong-do-jeon is perfectly consistent with the old river area of Gojoseon, and in particular, considering Gojoseon was in the hostile relationship with Yan, it was found that only Myeong-do-jeon was used without using any other Chinese currency in the entire Gojoseon area, not just some areas. It is also a decisive clue to prove that it is not the Yan currency. The limitation of this study in developing the discussion different from the current research and study is that there was a lack of exploration and investigation of various documents and relics. For future research, this study will become more meaningful when it is conducted simultaneously with the discovering of new documents as well as the relics.
