This study aims to identify the place and location of Gasan around Cheonggyecheon in the Joseon Dynasty, and also to examine the current status of their changes or disappearance in the process of modernization. On top of literature research on old document and maps related to dredging of Cheonggyecheon, the field survey to understand the actual status and location of Gasan was conducted. The study contents are like below. First, through old document and maps related to Cheonggyecheon in the Joseon Dynasty, the contents and records related to Gasan around Cheonggyecheon were selected. Such Gasan were mainly built up by dredging work of branch/streamlet in the era of King Sejong, and also the large-scale dredging during the period of King Yeongjo. Second, the location of Gasan and forest around Cheonggyecheon shown in old maps was understood. With Ogansumun(Five-arched Floodgates) as the center, they were constructed on both hills of Cheonggyecheon inside/outside of the capital city, and its surrounding branches. Third, based on the measures to create a scale map based on Susunjeondo, the location of Gasan on old maps was found on the current map, and then the current status of places expressed as Gasan was surveyed. In the results of the study, even though most of the Gasan built up around Cheonggyecheon in the Joseon Dynasty have disappeared by the urban development performed since the end of 19th century, still, there are some remains left.

Rebels emerge after the late Joseon. Hong Gyung-rae will fight against the military by gathering dissatisfaction forces with regional and status discrimination. Gasan supervisor Jung - Si in the first battle. He urged him to surrender and participate in the rebellion, but Jung - Si refused to die. Surrounding officials did not protest and surrendered to the rebels. When Hong Gyeong-rae's rebellion subsided, the most damaging thing was the death of 2,000 people who were deceived and joined by Hong Gyeong-rae's propaganda. There would have been no death of the innocent people if the officials in charge of the government had actively defended them at the beginning of the rebellion. There is a need for a historical study on the time of the Gasan supervisor Jung-Si, who refused to surrender to the rebels and fought with death.

During the Late Joseon dynasty, abandoned mountain fortresses were urgently repaired for the operation of foothold mountain fortresses in Gyeongsang-do, during the Japanese Invasion of Korea in 1592 and immediately after the Qing Invasion of Korea in 1636. Immediately after the Qing Invasion of Korea, an external fortress wall was built and added to each of Cheonsaeng Fortress and Geumo Fortress to establish a system of protecting locals inside a fortress at important locations for border defense against Japan in the Yeongnam region. Cheonseng Fortress, however, did not have sufficient geographical and protection conditions as a mountain fortress for protecting people inside it; thus, Gasan Fortress was newly built to replace Cheonsaeng Fortress. Geumo and Gasan Fortresses were used in border defense against Japan during the period from King Injo's reign to the end of Joseon Dynasty, because the fortresses served the purpose of defending Nakdonggang River and middle roads located at important roads along the border in the Yeongnam region and because it was possible to quickly repair and use their existing fortress walls and internal facilities, such as middle fortress walls and ponds, that were constructed for long-term protection of locals inside the fortress. In addition, it was found, in this study, that a continuous discussion on how to supplement fortresses led to the reinforcement and improvement of fortress facilities and fortification technology through the application of major strengths of Chinese (Ming) and Japanese fortress systems.

The classification of the bone pieces excavated from Gasan-ri archaeological site 1 in Jinju, presumed to be relics was investigated macroscopically. The remains of the animal bone were 3 classes (Mammalia, Aves, Amphibia), 5 orders (Carnivora, Artiodactyla, Galliformer, Rodentia, Salientia), and 6 species (Sus scrofa, Cervidae sp., Nyctereutes procyonides, Phasianidae, Rattus norvegicus caraco, Rana nigromaculata). The total weight of the animal bone remains was 1,002.80 g, with the identified bones comprising 975.30 g and an identification rate of 97.26%. A total of 447 animal bone fragments were identified, including 204 bone pieces of S. scrofa (468.00 g, 47.99%), 102 bone pieces of Cervidae sp. (453.79 g, 46.53%), 68 bone pieces of R. nigromaculata (4.69 g, 0.48%), 59 bone pieces of N. procyonides (47.14 g, 4.83%), 9 bone pieces of Phasianidae (0.98 g, 0.10%), and 5 bone pieces of Rattus norvegicus caraco (0.70 g, 0.07%). The bone pieces of the animal relics consisted of 81 skull (18.12%), 161 axial skeleton (36.02%), 64 forelimb (14.32%), and 141 hindlimb (31.54%) fragments. The archaeological significance of the animal bones excavated in this investigation was that wild boars and deer were presumed to have been mainly used animals in the Gasan-ri area of Jinju during the Three Kingdoms period.

In Soil Taxonomy system, anthropogenic soils are still classified as Entisols since the International Classification Committee for Anthropogenic Soils is in the process of classifying anthropogenic soils as new orders. In reality, it is difficult to characterize anthropogenic soils because Soil Taxonomy (ST) system does not distinguish between natural and anthropogenic Entisols. On the other hand, World Reference Base for soil resources (WRB) considers human impacts on soils and contains an independent category of anthropogenic soils, which makes easier to understand anthropogenic soil characteristics than Soil Taxonomy system. A remodeled paddy field (Gasan) was selected to classify by ST and WRB. Soil samples were taken to analyze chemical and physical properties. Based on the results of the analyses, the ST system classified Gasan as coarse loamy, mixed, mesic, Aquic Udorthents while the WRB did as Stagnic Urbic Technosols (Oxyaquic, Arenic). As a conclusion, the WRB classification information of the anthropogenic provides more detail characteristics of the anthropogenic soils.

This study investigates and analyzes ancient literature records and iconographic materials to examine the Willow Tree Fence(樹柵) built on Gasan(假山) Cheonggyecheon(淸溪川) within the Hanyangdoseong, which was deliberately created to prevent flood damage during the Joseon Dynasty. Although there have been research cases related to the willow tree, it is difficult to find research conducted with the purpose of identifying its archetypal value by investigating and analyzing specific use cases of the willow tree and its historical background. Accordingly, this study aims to identify examples of the Willow Tree Fence(樹柵) created in Cheonggyecheon(淸溪川) during the Joseon Dynasty and reinterpret their value by illuminating the background of construction and regional characteristics. The main contents of this study are as follows. It is presumed that floods during the Joseon Dynasty were a great hazard. Between the 16th and 18th centuries, Joseon suffered severe damage from floods. By the time of King Yeongjo, all Four Mountains(四山) of the capital had become bare mountains, which was the cause of frequent floods. In the year of Gyeongjin(庚辰, the 26th year of King Yeongjo's reign, 1760), King Yeongjo dredged the channel bottom of Cheonggyecheon(淸溪川), which overflowed every rainy season, with the Juncheon Project(Channel-Dredging, 濬川事業) and planted willow trees on the mountain on both sides of the Ogan Water Gate(五間水門), as measures to prevent flood damage and soil loss. was implemented. In the <Doseongdo(都城圖)> in 《 Gwangyeodo(廣輿圖)》 produced in the mid-18th century during the reign of King Yeongjo, Gasan(假山), built in front of the Ogan Water Gate(五間水門) is visible, and in the record 『Sinjeung Donggukyeoji Seungnam(新增東國輿地勝)』 In the record, it appears that willows were planted on both sides of the mountain in the year of Gyeongjin(1760). With <Hanyangdoseong Map(漢陽都城圖)> produced in the 46th year of King Yeongjo's reign(1770), it is confirmed that willow trees formed a thick forest on Gasan Mountain near the Ogan Water Gate(五間水門) in the late 18th century. In addition, the Juncheon Project(Channel-Dredging, 濬川事業) and the creation of the Willow Tree Fence(樹柵) continued from the 15th century, the early Joseon Dynasty(朝鮮前期), to the end of the 19th century, the late Joseon Dynasty(朝鮮後期), through the records of ancient literature such as 『Annals of the Joseon Dynasty(朝鮮王朝實錄)』, 『Seungjeongwon Diary(承政院日記)』, and 『Records of Daily Reflections(日省錄)』. This study is meaningful in informing that the willow tree was a unique cultural heritage and traditional landscape resource by investigating the composition and use of the Willow Tree Fence in the Joseon Dynasty, which was a great basis for preventing floods and flood damage, as well as forming a beautiful landscape.

Human influence on soil formation has dramatically increased as the development of human civilization and industry. Increase of anthropogenic soils induced research of those soils; classification, chemical and physical characteristics and plant growth of anthropogenic soils. However there have been no reports on soil pore properties from the anthropogenic soils so far. Therefore the objectives of this study were to test computer tomography (CT) to characterize physical properties of an anthropogenic paddy field soil and to find differences between natural and anthropogenic paddy field soils. Soil samples of a natural paddy field were taken from Ansung, Gyeonggi-do (Ansung site), and samples of an anthropogenic paddy field were from Gumi in Gyeongsangnam-do (Gasan) where paddy fields were remodeled in 2011-2012. Samples were taken at three different depths and analyzed for routine physical properties and CT scans. CT scan provided 3 dimensional images to calculate pore size, length and tortuosity of soil pores. Fractal analysis was applied to quantify pore structure within soil images. The results of measured physical properties (bulk density, porosity) did not show differences across depths and sites, but hardness and water content had differences. These differences repeated within the results of pore morphology. Top soil samples from both sites had greater pore numbers and sizes than others. Fractal analyses showed that top soils had more heterogeneous pore structures than others. The bottom layer of the Gasan site showed more degradation of pore properties than ploughpan and bottom layers from the Ansung site. These results concluded that anthropogenic soils may have more degraded pore properties as depth increases. The remodeled paddy fields may need more fundamental remediation to improve physical conditions. This study suggests that pore analyses using CT can provide important information of physical conditions from anthropogenic soils.
