  • Within the Gyeongju Basin lies the central an ancient tombs (Wolseongbuk tombs), which are seen to be the core tombs of the Silla ruling class. An accurate understanding of the location of the ancient tombs, commonly known as a flatland area, provides a clue to understanding the contrast process and direction of the ancient tombs. This in turn requires an accurate understanding of the surrounding landscape, including where the ancient tombs are located. In other words, it must be possible to restore as much of the highland area as possible within the basin in which the ancient tombs are located. All data were analyzed as deeply as possible in order to identify the topographical features of the ancient tombs. As a result, it appears that the ancient tombs are located at the end of a fan or at the end of the line, and a large number of springs and wetlands are distributed around the area. This area is relatively low and unsuitable for generating high levels of moisture on the ground. These topographical features are directly related with the distribution of polymers, and solids were completely formed to avoid wetlands. Meanwhile, the ancient tombs are divided into several zones by springs and wetlands, and each area also has the characteristics of large groups where the boundaries are protruding and isolated. Also, this aspect was found to be true for the Oreung around Namcheon. After all, the location and distribution of Silla in the Daerungwon area are the result of the reflection of the fine geographical features of the Gyeongju basin, which are the key factors of springwater and wetlands.

  • A new alternative method based on HWAW method to detect underground anomaly was introduced. The location of underground anomaly can be estimated by using 2-dimensional image of phase velocity image with position and wavelength based on distortion phenomena of surface wave due to underground anomaly. Overall procedure of proposed method such as field testing, signal processing and interpretation of the result was introduced. Numerical verification study was performed by using various ground models containing underground anomaly. According to the condition of anomaly, the propagation and reflection characteristics of surface wave were different and this could be more easily shown in the image of phase velocity. Some rules of distortion phenomena were found and these become clues for estimating underground anomaly in interpreting real field data. Field verification tests were performed with conventional geophysical methods such as DC resistivity method and GPR. Though field condition is not homogeneous like numerical models, similar distortion phenomena were found in the testing results and estimated location of underground anomaly was agreed well with the results of another geophysical methods.

  • This article examines the process of how Daesoon thought keeps its own identity while being practiced as a religion in Korean culture through the perspective of theological hermeneutics of E. Schillebeeckx, a representative theologian in 20th century, especially on the centering of the matter of experience. Schillebeeckx says that an experience is an occurrence of perception by encountering something different from oneself. According to him, 1) the occurrence of perception is premised on a framework or form of interpretation which prescribes experience as the experience in the perceptive dimension. 2) A framework of interpretation is subject to pre-existing system or structure which already has formed a basis to the experience. It consists of various interpretative elements such as social form, general knowledges, various experiences, theoretical models in their society, etc.. 3) The experiences take place in the reflection of contemporary situation, and it is understood by a society, thus making it a social stream. This experience is expressed historically, gains historicity in the process of being handed down from person to person, from generation to generation. In this way, an experience starts to form a tradition. 4) The tradition is a historical stream which gives rise to, admits, and integrates various experiences, religious revelation, and faith etc. In this way, the tradition as a historical stream becomes a field of religious actuality such as revelation, salvation, etc. Conclusively, a religion takes place, is formed, only when it is understood anew by the people who live in that cultural tradition through their languages. The ground Daesoon thought takes place, is formed, is in this way. Daesoon thought takes place in the core of traditional Korean culture, undergoes changes when it encounters the other stream of traditional Korean culture, and the vice versa. Because of this inevitable change, ironically enough, Daesoon thought can maintain its own identity as Daesoon thought, and Korean culture its own identity as Korean culture, avoiding falling into the tertiary which is neither Daesoon thought nor Korean culture. It is in this way that any religion can be in the faithfulness to its starting point to be enriched and transformed in its interaction with the other tradition. At here is the reason Daesoon thought has to have an openness to the changing world.

  • This thesis examined Chu Hsi's self-cultivation theory as the representative theory of cultivation in Confucianism, while juxtaposing it to self-cultivation theory in Daesoon thought, concentrating on its similarity and difference. Neo-Confucianism is a scholarship which has wielded a tremendous influence upon East Asia, while functioning as an official scholarship for long period up to Yuan, Ming, and Ching period, after achieving its synthesis by Chu Hsi. After 13th century, Neo-Confucianism has been a representative academic system in Confucianism, and self-cultivation theory was in its center. It suggested various virtues that classical scholars have to equip to fulfill the sainthood and the politics of royal road. The self-cultivation theory of Chu Hsi was developed upon the basis of the theory 'Li-Qi' and the theory of mind. Here, the practice of Geokyung(morally awakened state with a reverent spirit in every moment) and Gyeokmul-tsiji(reaching into the utmost knowledge through investigation of things) formed a nucleus of Chu Hsi's self-cultivation theory. While Geokyung was to reveal one's true nature through cultivation of mind, Gyeokmul-tsiji was to demonstrate the complete use of mind's essence and function. Chu Hsi's self-cultivation theory attempted to realize the unity of heaven and man, and through cultivating self and governing people, it also tried to achieve its ideal of the society of Great Union(Daedong). Daesoon Thought is originated from Sangjenim who has descended to this world as a human being called Jeungsan. He went on his circuit to rectify the disorder of heaven and earth for 9 years to rectify the Three worlds of heaven, earth and human being which were faced with total annihilation due to its rule of mutual conflict, while creating an earthly paradise. Respecting the will of Sangjenim, Dojunim established the foundation of Do through launching 'Meukeukdo' and setting tenet, creed and object so that the cultivators (Doins) could believe and respect the truth of Sangje's great itineration (Daesoon). Among those, the two components of creed, which are four fundamental principles and the three fundamental attitudes are of great account as precept and cardinal point. Through this means, the cultivators of Daesoonjinrihoe aspire to guard against self-deception through transforming the human spirit, to realize earthly immortality through renewing human beings, and to create an earthly paradise through transforming the world. This thesis attempted to compare and analyze the theory of self-cultivation in Neo-Confucianism and Daesoon Thought in the aspect of ground, method, and object of cultivation. First, as for the ground of cultivation, the doctrines of Chu-tzu and Daesoon thought place the essence of cultivation on 'heaven'. Yet, whereas the former postulates Taekeuk (the Great Ultimate) as a principle as well as the heaven of a natural order, Daesoon thought postulates Sangenim as the heaven of superintendence as well as the heaven of a natural order, signified as its equation of Daesoon with circle, along with the unity of Meukeuk (Endlessness) and Taegeuk (the Great Ultimate). Further, the doctrine of Chu-zhu and Daesoon thought is identical in the point that both thoughts see mind as the subject of cultivation, while trying to restore a pure essence. Nevertheless, whereas Neo-Confucianism intends to give scope to ability of the complete use of mind's essence and function, Daesoon Thought sees mind as the essence which is used by spiritual beings and as an organ that heaven, earth and human being rely upon as the center of the universe. In the aspect of method of cultivation, the doctrine of Chuzhu lays emphasis on the rational factor in that it brightens its 'myung-deoki'(bright inner virtue),' while trying to correspond to the law of heaven on the basis of 'Geokyung' and 'Gyeokmul-tsiji.' On the contrary, Daesoon thought lays much emphasis on faith factor in that it aspires for human perfection based on the restoration of conscience by cultivating Daesoonjinri with sincerity, reverence and faith along with 'quieting the heart-mind', 'quieting the body', 'respecting the God of the Ninth Heaven', and 'observing ritual practice on the basis of the faith in Sangjenim. Yet, both thoughts have similarities in that cultivation of body forms the basis and that they attempt to realize their ideals through cultivation in daily life while taking 'Guarding against self-deception' as the key method of self-cultivation.' However, the principle of Chu-zhu can be said to be a voluntary and autonomous practice based on scripture of the saint as well as self-reflection. On the other hand, Daesoon thought reveals certain difference in that it combines faith factor with one's self-effort by concentrating on cultivation under the presence of Sangjenim as the object of belief and the spirits of heaven and earth. In the aspect of object of cultivation, both thoughts share similarities in that the saint and the perfected gentleman with a moral virtue as an ideal image of men in both thoughts attempt to realize each of their 'myung-deok' in human nature as a heavenly mandate while respecting morality. Further, they also share similarity in the point that the desirable characters in both thoughts want to participate in harmonious creation and nurturance. Yet, the perfected gentleman with a moral virtue is also characterized by its aim for a new heaven and earth where there is no mutual conflict but mutual beneficence, by promoting the moral influence and virtue of Sangjenim over one's own virtue, while practising the mutual beneficence of all life through harmonious union of divine beings and human beings.

  • This study aims to investigate the complex planning processes and design ideas of the Gwanghwamun Plaza which was opened in 2009. The opening of the plaza was significant as it was built in order to restore the symbolic meaning of axis in the historical Joseon Dynasty that was distorted during the Japanese Imperialism. The plaza itself attracts many citizens and tourists by providing the empty ground carrying historical ambiences around. In this paper, the story of the Gwanghwamun plaza will be summarized. Particularly, the background of promoting the project will be discussed and the whole planning process will be dealt with. The plaza was realized through several stages. First, the planning stage will be reviewed. The planning stage had been a quite long process since the initial idea was discussed. Since the early 90s, the political decision of making the plaza was made through the change of people's understanding toward public space. At this stage, the city government worked together with diverse citizens and professionals to share the vision and to realize the right decision in making the plaza. Second, the design stage will be elaborated in detail. This is the second design stage. The former was the idea competition and the latter was the turn-key base. The final design scheme emphasized the restoration of symbolic axis and the forgotten Yukjo Street. The scheme consists of four zones such as history restoration zone, prospect and history representation zone, culture zone, and the urban zone. Through the whole design process, the original idea remained as it was. The design concept was "a place of memory and prospect." It emphasizes the history representation, view corridor, cultural activities platform as well as the emptiness and flexibility of the basic premise of the plaza. Finally, the construction stage will be discussed. There were some additions and omissions in the construction process. The design chances in the construction stage will be reviewed in detail. After the opening of the plaza, there were some changes in the detail design. We will discuss how and why these modifications were made. In the end, the social and cultural implication of the plaza will be discussed. The storytelling of the Gwanghwamun Plaza will contribute to the clear understanding of planning and design process of pubic places. Based on this reflection, we are able to think about some suggestions of public projects for the future.
