The purpose of the study was to understand the symbol and locational meanings in building and relocating Gwangje-jeong(光霽亭) through the analysis and interpretation on the construction background, history, the location and its characteristics. Concerning physical environment, human activities, the symbol and meanings of the formal Gwangje-jeong site and the present location, the study was concluded about the site and its meaning of tradition as following. Gwangje, the name of the pavilion, represents the fidelity of Maedang(梅堂) Yangdon(楊墩) who refused as Seonbee(a man of virtue) to be tainted with the corrupt world, which was related with the situation at that time. It implies Maedang's feeling of realizing Noojeongjeyong(樓亭題詠) of Gwangje-jeong along with the high spirit of Gwangpoongjewol(光風霽月). According to the record about rebuilding Gwangje-jeong, Maedang was the very person who planted plum flowers at the pavilion and put up the tablet of its name, Gwangje. Even after his death, Gwangje-jeong was the symbol indicating Yangdon, given the triple high ground and the planting of plum flowers. Also, Sookho(宿虎) town at the entrance of Gwangje-jeong and Bokhoam(伏虎巖: a rock) at the right side of the pavilion signifies the location for praising Maedang Yangdon, and the Yangjipha's Oensi(五言詩: five words verse) engraved on the rock gives a good description about the place, Agyesa that worshiped Yangdon. As Agye-Sa(阿溪祠) where Yangdon was worshiped and praised had been abolished in the 5th year under the Kojong's reign(1868), the spirit praising Maedang had finally been used for the relocation of Gwangje-jeong. Despite the relocation of Gwangje-jeong, the old Gwangje-jeong site has remained at least for 359years at Hucheonli, and its surroundings have maintained the name 'Gwangje' as the front place name morpheme, for example, 'Gwangje-jeong,' 'Gwangje Town,' 'Gwangje Bridge' and 'Gwangje Creek,' for symbolizing the praising of Maedang. Gwangje-jeong, as the center place of solidarity among Namwon Yang's family clan, has been able to maintain its symbol and meanings in spite of relocation, mainly because of the fellowship among the descendants, family clan and alumni who respected virtuous achievements of ancestors and shared the agony of the time. In addition, the symbolism has been preserved since the spirit of Gwangpoonjewol of Yangdon and his high character were cherished along with the spirit of Bongseon(奉先) that inherited and kept virtuous achievements of ancestors.

In this study, pieces of statements of sinawi successors, which served the ground of sinawi theory of Lee(that are found only in reports and theses) were searched from notebooks or cassette tapes of Lee. Then, this study tried to trace the process that the theory of sinawi was established based on the fieldwork of sinawi and relevant data, and to shed light on the significance. With the understanding from the early days that life of minsokak can be found in musical scenes in the region, Lee wandered around the scenes of minsokak(folk music) in the nation, recorded minsokak, and collected dialogues with successors of minsokak with about 2,000 cassette tapes and 300 notebooks. Especially, in the fieldwork data on sinawi that Lee possesses contain dialogues with the newly found sinawi successors that Lee found in the scene of sinawi in Gyeonggido province, Jeollado province, and Gyeongsangdo province over numerous visits for over 20 years from the early 1970s. Sometimes the record includes improvised sinawi performance. As the fieldwork of sinawi by Lee was conducted comparatively early, there are a lot of testimonies of successors who remember the sinawi scene of the past. Using these data, Lee published theories related to sinawi on reports and theses. His representative thesis is about 'Sinawi Chung'(1979). After listening to the testimony of Younghee Ji, the master of Gyeonggi haegeum sinawi in his first fieldwork of sinawi, he started his research on sinawi chung of piri, daegeum, and haegeum in Gyeonggido province and Honam area. Based on the testimonies on sinawi chung of 11 sinawi successors, Lee published 'Sinawi Chung'. In 1987, he extended the scope his research to sinawi-kwon(圈), which includes Gyeongnam area, found 12 new sinawi successors in Gyeonggi, Honam, and Gyeongnam areas, and based on their testimonies, complemented the theory of sinawi chung and published it. Fortunately, most of the dialogues with sinawi successors quoted in his reports or theses are recorded in his notebooks or cassette tapes. When these data are released, it is expected that a new theory of sinawi or minsokak will be born.

What I wish to show in this paper is the moral educational implication on "The Minor Annotations of Elementary Learning(小學枝言)" in a position to consider the alternatives about personality education problems by searching viewpoints on moral training theory on the book. "The Minor Annotations of Elementary Learning(小學枝言)" was written by Dasan Jeong-yakyong(茶山 丁若鏞, 1762-1836). In the oriental philosophy, a moral training theory is built on the base of human nature theory. Dasan's moral training theory was also built on his human nature theory. Undoubtedly we could consider that his difference from the moral training theory of Confucianism is reflected in his moral training theory putting stress on practice. Dasan criticized the moral training theory of Confucianism because of its static aspect contemplating mind internally. He stands on the position that the virtue can be come true by the concrete practice. The establishment ground of Dasan's moral training theory is on his theory of human nature's preference(性嗜好說). Dasan didn't consider benevolence, righteousness, propriety, and wisdom(仁義禮智) as human nature. He considered that the human nature prefers goodness. So there is no perfect human nature or principle originally to human beings but also directionality to be displayed. We can say that the virtue building by cultivation of directionality get connected to moral training theory. Dasan considered ?The Minor Annotations of Elementary Learning(小學枝言)? as a practice book for moral training which develops individuals' personality through practice in the reality. He thought that the book cause individuals to follow 'the elementary way(小道)' and to learn 'the elementary art(小藝)' more than academic pursuit. From this viewpoint he showed the practice(行事) of judgment(權衡) by keeping the attitude for the scripture interpretation to pursue the right principles(義理) based on Chinese exegetics(訓?) and the historical evidences(考證) through the whole book. And in the book he suggested the standard of the whole-person education to develop the human nature based on his theory of human nature's preference(性嗜好說), to cognize relationship as an ethical existence, and to pursue the harmony with graphonomy(字學) and Ethics(道學). So we can regard that he realized his practice centered moral education philosophy in the book.

Jang Hyeon-gwang(張顯光, 1554-1637), whose pseudonym or courtesy name is 'Yeoheon(旅軒)', had made a thorough study on the intrinsic nature of Neo-Confucianism in a more sincere fashion, when comparing him with other Neo-Confucianists in Joseon period. Also he was a renowned scholar who expanded its philosophical system in-depth. Yeoheon thereby had strengthened his philosophical system accordant with the Great Learning(大學) and Doctrine of the Mean(中庸), which are the fundamental systems of Neo-Confucianistic education. Based on such considerations, Yeoheon's thought on education can be illuminated from three different perspectives. First, Yeoheon deepened his a theory of good governance by a virtuous ruler(聖人君主論, pronounced, 'Seongingunjuron') as the standard of education. Essentially, his theory pursues Refraining from desire, and preserving the laws of nature(存天理?人欲, pronounced, 'Joncheolliarinnyok'), and put emphasis on ethical awakening, and the governance through a virtue of moral excellence. Second, Yeoheon stressed the learning theories related to 'sincerity' or true heart(誠) and 'piety' or 'respect'(敬)) as the form of education(誠敬, pronounced, 'Seonggyeong'). Also he expounded that people needs "to establish a ground of Respect and Sincerity in their mind." He recognized the differences between the two virtues, meanwhile, however, he understood it as in an identical context. Third, Yeoheon advocated harmony between separation and integration(分合, pronounced, 'Bunhap') as a method for education. Through his unique 'Discourse on Longitude and Latitude', dubbed, 'Li-Gi Gyeongwiseol (理氣經緯說) in which the principle(Li, 理) is equal to the intrinsic energy or material force(Gi, 氣), he maintained his view on the Doctrine of the Mean, in that he was not inclined to either sides according to the logic of Change(易, pronounced 'Yeok'). When reviewing Yeoheon's contemplation in education in the meaning of modern education, he laid the standards for education on the establishment of morality, and he also provides us with an idea which induces us to look through the form and method for education from the perspective of Doctrine of the Mean. In short, Yeoheon's view on education embodies wisdom of traditional Neo-Confucianistic Education having consistency, and it provides for an implication of the review of the importance of the balance in relation to methodological bias toward confusion in the standards for modern education, and unsystematic contents therein.

This study takes as its text "Yangarok", the record written by Mukjae Lee Mun Geon (1494-1567) about his grandson rearing and examines the conflicts between the grandfather and the grandson. The reason it is focused on the conflicts between the grandfather and the grandson particularly among many aspects of Yangarok is that the paper notices the dual feelings of love and hatred lying in the mind of Mukjae, the subject of the narrative. Because the record of grandson rearing plainly reflects the dual elements of the grandfather, love and hatred, expectation and disappointment, and hope and resignation, it shows the acute conflicts between the two persons well. At the time of the grandson's birth, Mukjae went through a gloomy period both in family and socially. He had to taste tremendous frustration in the status as an exile pushed back from the center of the political world, and his only son was handicapped, so he could not expect his caring after that. Spending each day in such frustration, he faced the birth of his grandson just like a miracle. However, the excitedness and expectation he had in the beginning of the child raising were turned into disappointment and complaining as time went by. His change lets us think about the distance between love and hatred existing in human relations. This study analyzes Yangarok but is focused on the conflicts between the grandfather and the grandson for further discussion, so it attempts to understand Yangarok from a different perspective. First of all, Chapter 2 of this article notices the fact that cause results in effect and examines the ultimate factors raising grandfather-grandson conflicts. Next, Chapter 3 considers the concrete aspects of grandfather-grandson conflicts. Based on the above examination on the causes and aspects of the conflicts, Chapter 4 focuses on the value that Yangarok has as the material for introspection and lays the ground to think about the messages that this record implies for contemporaries.

Zhōuyì周易 is intended to explain the affairs of human beings by observing the images and works of all things in the universe, abstracting them into the $b{\bar{a}}gu{\grave{a}}$八卦, calculating the process and inducing the outcome by the method of stalk divination, in which this paper finds the origin of natural scientific thought of Zhōuyì. The way of Zhōuyì's thought on the natural science is distinguished from that of the Western's. In the West, people dismantled the objects into the parts until they reached the atom and analyzed them by the principle of causality to draw an axiomatic truth. In the meantime Zhōuyì observed and studied the dynamic functions and changes of all things for the convergence of the whole. While the way of Zhōuyì's thinking could have not contributed to the development of modern scientific development, that of the West overwhelmed Asian development passing through the period of enlightenment during 16-17 century. This paper tries to articulate the points where Zhōuyì can share its theory with the contemporary science by finding the traces of scientific thoughts in Zhōuyì. It encounters its ground from the methodology of natural science and scientific statements proposed by Zhōuyì. The essential concepts of Zhōuyì are induced from all things in nature. This can be considered as the idea of '法自然'(emulating the patterns and examples from nature). Also they observed the images and changes seen by the habits of animals, plants and human beings to sense and perceive their laws. These are regarded as the methodology of natural science in Zhōuyì. As a book of divination, the way of stalk divination is designed to calculate the future by using the system of 'numbers'. 'tàijí太極', ' yīnyáng陰陽', 'four symbols四象', '$b{\bar{a}}gu{\grave{a}}$八卦' and 'wǔxíng五行' are the essential concepts of Zhōuyì to represents the dynamic phenomena and changes of the natural order. Among them '$b{\bar{a}}gu{\grave{a}}$八卦' is a presentment to explain the structure of the world not by the individual analysis of things but by the unification of the whole through the contradictions and interchanges among them to reach the new orders. As of now, the studies of Zhōuyì in Korea have focused on the traditional perspectives, such as political and ethical philosophy. Some of recent studies, having interpreted Zhōuyì with scientific inclination have generated controversy 'Can Zhōuyì be a science?', for which scholars have hard time to reach the agreement. This paper tries to find the headwaters of the contemporary natural science by elaborating the methodology of natural science stated in Zhōuyì.

Noksan is a green area in the form of a hill located inside Gyeongbokgung Palace, unrecognized as a cultural heritage space. This study analyzed the literature and the actual site to derive its landscape meaning by examining the background for the formation of Noksan and how it changed. As a result, the identity of Noksan was related to the geomagnetic vein, pine forest, and deers, and the following are its landscape meaning. First, several ancient maps, including the 「Map of Gyeongbokgung Palace」 depicted the mountain range continuing from Baegaksan(Bugaksan) Mountain to areas inside Gyeongbokgung Palace, and Noksan is a forest located on the geomantic vein, which continues to Gangnyeongjeon Hall and Munsojeon Hall. On Bukgwoldo(Map of Gyeongbokgung Palace), Noksan is depicted with Yugujeong Pavilion, Namyeogo Storage, office for the manager of Noksan, the brook on north and south, and the wall. It can be understood as a prototypical landscape composed of minimal facilities and the forest. Second, the northern palace walls of Gyeongbokgung Palace were constructed in King Sejong's reign. The area behind Yeonjo(king's resting place) up to Sinmumun Gate(north gate of the palace) was regarded as the rear garden when Gyeongbokgung Palace was constructed. However, a new rear garden was built outside the Sinmumun Gate when the palace was rebuilt. Only Noksan maintained the geomantic vein under the circumstance. However, the geographical features changed enormously during the Japanese colonial era when they constructed a huge official residence in the rear garden outside the Sinmumun Gate and the residence of the governor-general and road in the site of the Blue House. Moreover, Noksan was severed from the foothill of Baegaksan Mountain when 'Cheongwadae-ro(road)' was constructed between the Blue House and Noksan in 1967. Third, the significant characteristics and conditions of the forest, which became the origin of Noksan, were identified based on the fact that the geomatic state of the northeastern side of Gyeongbokgung Palace, the naecheongnyong area in geomantic terms(the innermost 'dragon vein' among the veins that stretched out from the central mountain toward the left side), and they planted pine trees to reinforce the 'ground vein' and the fact that it was expressed as the 'Pine Field' before the Japanese Invasion of Korea in 1592. The pine forest, mixed with oaks, cherries, elms, and chestnuts, identified through the excavation investigation, can be understood as the original vegetation landscape. Noksan's topography changed; a brook disappeared due to mounding, and foreign species such as acacia and ornamental juniper were planted. Currently, pine trees' ratio decreased while the forest is composed of oaks, mixed deciduous trees, some ailanthus, and willow. Fourth, the fact the name, 'Noksan,' came from the deer, which symbolized spirit, longevity, eternal life, and royal authority, was confirmed through an article of The Korea Daily News titled 'One of the seven deers in Nokwon(deer garden) in Gyeongbokgung Palace starved to death.'

This study aims to report the behavioral mechanism of steel pipe reinforcement grouting, which is being actively used to ensure the stability of the excavation surface during tunnel excavation, based on measurements taken at the actual site. After using a 12 m steel pipe attached with a shape displacement meter and a strain gauge to reinforce the actual tunnel surface, behavioral characteristics were identified by analyzing the measured deformation and stress of the steel pipe. Taking into account that the steel pipes were overlapped every 6 m, the measured data up to 7 m of excavation were used. In addition, the behavioral characteristics of the steel pipe reinforcement according to the difference in strength were also examined by applying steel pipes with different allowable stresses (SGT275 and SGT550). As a result of analyzing the behavior of steel pipes for 7 hours after the first excavation for 1 m and before proceeding with the next excavation, the stress redistribution due to the arching effect caused by the excavation relaxation load was observed. As excavation proceeded by 1 m, the excavated section exhibited the greatest deformation during excavation of 4 to 6 m due to the stress distribution of the three-dimensional relaxation load, and deformation and stress were generated in the steel pipe installed in the ground ahead of the tunnel face. As a result of comparing the behavior of SGT275 steel pipe (yield strength 275 MPa) and SGT550 steel pipe (yield strength 550 MPa), the difference in the amount of deformation was up to 18 times and the stress was up to 12 times; the stronger the steel pipe, the better it was at responding to the relaxation load. In this study, the behavior mechanism of steel pipe reinforcement grouting in response to the arching effect due to the relaxation load was identified based on the measured data during the actual tunnel excavation, and the results were reported.

The purpose of this study was to select a suitable planting substrate for multilayered plantings in an apartment landscape space. The experiment was conducted between May to October 2019, at the National Institute of Horticultural and Herbal Science. Planting substrate was prepared in six repetitions of eight treatment zones using mulching material, horticultural soil, bottom ash, and subgrade soil. Rosa hybrid 'Barkarole' and Hydrangea macrophylla 'Nikko Blue' were selected as the experimental plants. We investigated the monthly variation and effect of the substrate type on the growth (plant height, number of branches, leaf length, leaf width, and plant area of the substrates) of the plants. In R. hybrid 'Barkarole' grown in 20 cm of horticultural soil and 10 cm of bottom ash, the plants were taller(102.2±5.8 cm), had more branches (5.5±0.6 each), longer leaves (10.9±1.0 cm), and greater leaf width (6.2±0.5 cm) and plant area (4077.1±416.6 cm²)(p<0.05). H. macrophylla 'Nikko Blue' showed the best growth from 3cm of mulching, 20cm of horticultural topsoil, and 10cm of bottom ash, which resulted in taller plants (43.6±2.1 cm), more branches (4.9±0.8 each), longer leaves (7.2±0.5 cm), and greater leaf width(4.3±0.3 cm) and plant area (344.5±43.2 cm²). Through this study, it was possible to propose an optimal planting substrate for shrubs for multi-layered landscaping.

The purpose of this study is to reveal the tendency of planting design through the analysis of the planting of designer's gardens in the Suncheon Bay National Garden and to derive implications for future garden planting designs. The results of the study are as follows: First, the results of the study show that the practice of tree-based planting is still valid. Large growing trees such as 'Pinus densiflrora', 'Celtis sinensis', 'Zelkova serrata', 'Machilus thunbergii', 'Pinus strobus' overwhelmed the size of the designer's garden(150 to 390㎡). Second, the selection of trees tended to be made considering the designer's intention and the decorative effects rather than by considering the physiological and ecological conditions of the site. Third, among the herbaceous, the rate of the planting of perennials was high. Fourth, the flowering period of planted herbaceous was the most common in summer, followed by spring, fall, and winter. Fifth, the frequency color of the planted herbaceous was the most common in summer, followed by spring, fall, and winter. Fifth, in terms of flower color frequency, the most common was the yellow-series, followed by red-series, blue-series Sixth, average height herbaceous plants(20~60cm) were planted the most(47.4%). Seventh, structural plants that determined the garden's framework depended on trees, and the focal plants mainly utilized were evergreen trees, and the midrange plants were the planted herbaceous plants. The implications derived from the above findings are as follows: First, to ensure the garden's quality and sustainability, the selection of trees should be carefully considered, not considering only the artist's intention but also taking into account the physical and ecological conditions. Second, herbaceous plants can be used in various ways― the garden's focal plants, midrange plants, and ground covers, so more active herbaceous planting needs to be considered. Third, in consideration of the winter landscape, herbaceous planting using characteristics, such as fruits and stems, as well as flower colors should be considered. Fourth, blue and black color herbaceous plants have a noticeable effect even in a small amount, so it is necessary to plant them actively. Fifth, for the design of herbaceous planting, where the individual property of plants can be expressed, the design method should be considered.
