There are 35 cultural properties of fourteen kinds in the Demilitarized Zone known so far, but this number is expected to increase in the future. Among them, Cheolwon-Doseong and Jeongol-Chong of Gimhwa should be the first step toward conservation efforts by conducting a joint investigation through the collaboration of North and South Korea. In particular, the joint investigation of Cheolwon-Doseong will not only remind the North and South that they are the same people who have had common history and cultural traditions for a long time, but will also give symbolic meaning to convert the demilitarized zone into a stage for peace. Since Jeongol-Chong is a mass grave of the fallen soldiers of Pyeongan Province who fought against the invasion of the Qing of China, it should be managed as a national designated cultural asset through joint investigation. In addition, the Demilitarized Zone should become a World Heritage Site because of its importance to the legacy of the Korean War, an international war caused by an ideological confrontation. Furthermore, it has more than 6,000 kinds of temperate forests in addition to 100 species of endangered species and natural monuments. The DMZ is very qualified to be a World Natural Heritage Site, and should be included as a World Complex Cultural Heritage Site that qualifies as a World Heritage and World Natural Heritage Site. In the Demilitarized Zone, we can also find numerous highlands, tunnels and posts used during the Korean War, as well as surveillance posts, a military demarcation line, barbed wire fences, and Panmunjom, which were created by the armistice agreement. it would be desirable to select some of its sections and war facilities and to register them as modern cultural heritage assets. Finally, it is necessary to reconstruct the Dorasan Signal Fire Site, which was the communication facility of a traditional era which connected the South (Dorasan) and North (Gaesong). This would symbolize smooth communication between the two Koreas. In order to prepare for the reckless development of the Demilitarized Zone due to the upcoming cease-fire, the government and cultural asset experts will have to work hard to identify and preserve the cultural properties of the Demilitarized Zone, and they will also have to maintain consistent control over matters such as indiscriminate investigation and mine clearance.

The purpose of this study was to analyze , which was made in the late Joseon Dynasty to specify the vegetation landscape of the Donhwamun Gate area in Changdeokgung Palace. The study results can be summarized as below. First, based on "Jieziyuan Huazhuan(芥子園畵傳)", the introductory book of tree expression delivered from China in the 17th century, allowed the classification criteria of the trees described in the picture to be established and helped identify their types. As a result of the classification, there were 10 species and 50 trees in the Donhwamun Gate area of . Second, it was possible to measure the real size of the trees described in the picture through the elevated drawing scale of . The height of the trees ranged from a minimum of 4.37 m to a maximum of 22.37 m. According to the measurement results, compared to the old trees currently living in Changdeokgung Palace, the trees described in the picture were found to be produced in almost actual size without exaggeration. Thus, the measured height of the trees turned out to be appropriate as baseline data for reproduction of the vegetation landscape. Third, through the Rubber Sheeting Transformation of , it was possible to make a ground plan for the planting of on the current digital topographic map. In particular, as the transformed area of was departmentalized and control points were added, the precision of transformation improved. It was possible to grasp the changed position of planting as well as the change in planting density through a ground plan of planting of . Lastly, it was possible to produce a three-dimensional vegetation landscape model by using the information of the shape of the trees and the ground plan for the planting of . Based on the three-dimensional model, it was easy to examine the characteristics of the three-dimensional view of the current vegetation via the view axis, skyline, and openness to and cover from the adjacent regions at the level of the eyes. This study is differentiated from others in that it verified the realism of and suggested the possibility of ascertaining the original form of the vegetation landscape described in the painting.

This study was conducted to investigate the changes in Scenic Spots by utilizing the "Sinjeungdonggukyeojiseungram(新增東國輿地勝覽)" and "Joseonhwanyeoseungnam(朝鮮?與勝覽)" to interpret "Joseonmyeongseungsiseon(朝鮮名勝詩選, 1915)". By examining the historical context when "Joseonmyeongseungsiseon" was published, it documented the Japanese's memories of 'Sino-Japanese War(淸日戰爭)' in 1894, which implies the 'policy of assimilation' by the Japanese Government-General of Korea after the Japanese annexation of Korea(1910). Detailed information about the author 'Narushima Sagimura(成島鷺村)' can be found in preface. In the "Joseonmyeongseungsiseon", it dedicates most of the part in describing the Scenic Spot especially in 'Anseong Do (15 lines)', where has the memories of war such as the 'First Sino-Japanese War'. The number of Scenic Spots, commonly mentioned in both "Sinjeungdonggukyeoji seungram" and "Joseonhwanyeoseungnam" in Cheonan province are 13 in total. Most of the content contains a similar structure. But 'Honggyeongwon(弘慶院)' and 'Seonghwanyeok(成歡驛)' has both the common Joseon Dynasty landscape point of view, and the additional historical context which are about the 'Jeongyujaeran(丁酉再亂)' or 'First Sino-Japanese War' consequently enlightens the 'placeness' of the Scenic Spots. Among the newly described Scenic Spots, 'Anseongdo(安城渡)' is the part that focuses on the memory of the 'Anseongcheon Battle' that gave Japan its first defeat in the Sino-Japanese War. Especially, by introducing the poetry of 'Sinobu Shunpei' it maximizes the appreciation through emphasizing the direct correlation between placeness and the poem itself. While the Joseon Dynasty poems are 10 pieces in total and their title and the subject matters are all related to historical spots, and the appreciation also maximizes when fully interpreted with understanding the historical context. However, it's contextual meanings are neglected by dividing the actual structures into separate pages. When looking at the location of famous historic sites, they come in many different types, considering the location, meaning, size, and conditions surrounding them. It appears as a service space for travelers, a place for sightseeing, relaxation or return, a temple space for paying respects or memorial services, a fortress facility for defense and protection, or a fishing area for wages, and an old battlefield. Especially, it is noted that the area is diverse as the cultural landscape of Cheonan, given that the battle space between the hermitage and the Donghangnongmin(東學農民) is shared with each other. It is necessary to establish policies for the preservation and restoration of local cultural assets based on these points in the future.

Mt. Baekdu is a stratovolcano located at the border between China and North Korea and is known to have formed through its differentiation stage after the Oligocene epoch in the Cenozoic era. There has been a growing interest in the magma re-activity of Mt. Baekdu volcano since 2010. Several research projects have been conducted by government such as Korea Meteorological Administration and Korea Institute of Geoscience and Mineral Resources. Because, however, the Mt. Baekdu volcano is located far from South Korea, it is quite difficult to collect in-situ observations by terrestrial equipment. Remote sensing is a science to analyze and interpret information without direct physical contact with a target object. Various types of platform such as automobile, unmanned aerial vehicle, aircraft and satellite can be used for carrying a payload. In the past several decades, numerous volcanic studies have been conducted by remotely sensed observations using wide spectrum of wavelength channels in electromagnetic waves. In particular, radar remote sensing has been widely used for volcano monitoring in that microwave channel can gather surface's information without less limitation like day and night or weather condition. Radar interferometric technique which utilized phase information of radar signal enables to estimate surface displacement such as volcano, earthquake, ground subsidence or glacial movement, etc. In 2018, long-term research project for collaborative observation for Mt. Baekdu volcano between Korea and China were selected by Korea government. A volcanic specialized research center has been established by the selected project. The purpose of this paper is to introduce about remote sensing techniques for volcano monitoring and to review selected studies with remote sensing techniques to monitor Mt. Baekdu volcano. The acquisition status of the archived observations of six synthetic aperture radar satellites which are in orbit now was investigated for application of radar interferometry to monitor Mt. Baekdu volcano. We will conduct a time-series analysis using collected synthetic aperture radar images.

This paper investigates Buddhist sculptures of the Gulsan-sa School of Seon Buddhism, which was established by the priest Beomil(梵日) at Myeongju(溟州), present-day Gangneung(江陵) area, and prospered until the late Goryeo period. There are very few surviving Buddhist images at Gulsan2 temple-site showing the Buddhist art when Beomil or his disciples, Gaecheong(開淸) and Haengjeok(行寂), were active, except a set of huge stone pillars for temple-banners and a stone monk stupa. It is therefore necessary to focus on pieces of artworks in Gangneung and nearby areas to explore the characteristics of Buddhist art of Gulsan-sa from the late Silla to early Goryeo period. For example, the stone relief seated Buddha image, one of Four Buddhas of Four Directions, and a stone relief of standing Guardian King both from the stone pagoda at Mujin temple-site(無盡寺址) can be compared with stupa reliefs at the capital Gyeongju area in their high quality of carving. The stone octagonal base showing seven lions on each of seven sides at Boheon-sa(普賢寺) demonstrates that it was made as a part of an octagonal lotus pedestal for a Vairocana Buddha now lost. Since Boheon-sa was erected by Gaechung, a disciple of Beomil as a branch of Gulsan-sa, it is fair to assume that the Vairocana image at Boheon-sa might have been closely related to the Buddhist images at Gulsan-sa in its style and iconography. The stone seated Bodhisattva from Hansong temple-site(寒松寺址) displays a benign face, exquisite necklace, and exotic iconography in its hand gesture and high cylindrical crown. The stone seated Buddha at Cheonghak-sa(靑鶴寺), brought from a temple-site where fragments of roof-tiles with the inscription of Heukam-sa(黑岩寺) were discovered, displays the late Silla and early Goryeo period. Heukam-sa seems to have been related to Gulsan-sa or have been one of the branches of Gulsan-sa. Extant fragments of artworks at Myeongju implicate the high quality of Buddhist art of Gulsan-sa in its iconography and style as well as unique features of Gulsan-sa Seon School.

This paper investigates the royal collection of paintings and calligraphy during King Gojong's (高宗) reign (1897~1907) based on the function of the Jipgyeong-dang Hall (緝敬堂), situated at "sleeping realm (寢殿)," Gyeongbok Palace. Using the surviving palace records and art works this study argues that the date of building the hall is approximately confined to the year of 1890. Not being matched with the general opinion that the Jipgyeong-dang Hall was used for the official meeting with envoys, this hall functioned as the main place for royal audience and the storehouse for archives. The role of Gojong as collector and patron was essential not only to the maintenance of the collection but also to the strengthening of royal authority just before the Japanese annexation in 1910. The specific titles of the collection at this hall can be verified through the Catalogue of the Books, Paintings, and Calligraphy Exposed to the Sun at Jipgyeong-dang Hall (緝敬堂曝曬書目) dating to the nineteenth century. The records of the catalogue inform us that more than 1,000 paintings and pieces of calligraphy, inkrubbings from old steles, manuals for painting, and encyclopedia concerning art theories from Korea, China, and Japan were preserved there. The collection of Jipgyeong-dang Hall resulted from Gojong's policy to foster the collection of contemporary Chinese and Japanese art works and various catalogues. Standing behind the Gyeongbok Palace, the Jibok-jae Hall (集玉齋) also preserved the diverse sources of practical learning, as did the Jipgyong-dang Hall for Gojong. The enormous royal collections by Gojong might have been constructed in accordance with the royal artistic taste and the artistic milieu of the late Joseon period. The surviving royal catalogues confirm this assumption as documentary evidence.

This study aims to identify the characteristics of oxidation and chemical composition of PM in winter season, 2017 at Incheon area. The mean concentration of air pollutants were $46{\pm}22{\mu}g/m^3-PM_{10}$, $29{\pm}18{\mu}g/m^3/-PM_{2.5}$, $5{\pm}3ppb-SO_2$, $0.56{\pm}0.24ppm-CO$, $21{\pm}13ppb-O_3$ and $28{\pm}17ppb-NO_2$, respectively. The dominant ion of the $PM_{1.0}$ chemical component were organic with $3.2{\mu}g/m^3$ and nitrate with $1.9{\mu}g/m^3$. The day and night variation of the $PM_{1.0}$ chemical components was higher in nighttime than those of daytime. The averaged nitrate oxidation rate (SOR) was 0.06 and sulfate oxidation rate was 0.11 during the field campaign. In the high mass loading period, nitrate oxidation rate (NOR) was up to 0.6 and also the nitrate in $PM_{1.0}$ was increased. The averaged ratio of $NO_x/SO_2$ was 8.7 and nitrate/sulfate was 3.1, respectively. In this results, the nitrate component in $PM_{1.0}$ was influenced by NOx from the stationary source as power plant and the mobile source around the measurement site.

Poor supervision and tourism activities have resulted in forest degradation in islands in Korea. Since the southern coastal region of the Korean peninsula was originally dominated by warm-temperate evergreen broad-leaved forests, it is desirable to restore forests in this region to their original vegetation. In this study, we identified suitable areas to be restored as evergreen broad-leaved forests by analyzing the environmental factors of existing evergreen broad-leaved forests in the islands of Jeollanam-do. We classified forest lands in the study area into six vegetation types from Sentinel-2 satellite images using a deep learning algorithm and analyzed the tolerance ranges of existing evergreen broad-leaved forests by measuring the locational, topographic, and climatic attributes of the classified vegetation types. Results showed that evergreen broad-leaved forests were distributed more in areas with a high altitudes and steep slope, where human intervention was relatively low. The human intervention has led to a higher distribution of evergreen broad-leaved forests in areas with lower annual average temperature, which was an unexpected but understandable result because an area with higher altitude has a lower temperature. Of the environmental factors, latitude and average temperature in the coldest month (January) were relatively less contaminated by the effects of human intervention, thus enabling the identification of suitable restoration areas of the evergreen broad-leaved forests. The tolerance range analysis of evergreen broad-leaved forests showed that they mainly grew in areas south of the latitude of 34.7° and a monthly average temperature of 1.7℃ or higher in the coldest month. Therefore, we predicted the areas meeting these criteria to be suitable for restoring evergreen broad-leaved forests. The suitable areas cover 614.5 km², which occupies 59.0% of the total forest lands on the islands of Jeollanamdo, and 73% of actual forests that exclude agricultural and other non-restorable forest lands. The findings of this study can help forest managers prepare a restoration plan and budget for island forests.

The purpose of this study was to analyze the habitat status and species diversity of benthic diatoms and estimate the applicability of TDI (Trophic Diatom Index) to obtain the basic data for the identification and management of created wetlands in the Nakdong River. We observed a total of 38 families and 173 species of benthic diatom during the survey period, and spring and autumn showed a similar number of species of 156 and 154, respectively. The result of the SOM (Self-Organizing Map) analysis showed that the distribution of benthic diatom was sensitive to environmental factors such as nutrient concentration and rainfall in each wetland. The cluster 1 was characterized by the survey sites of autumn mostly and consisted of points of high TDI, although the nutrients such as total phosphorus and total nitrogen were low, and the species number and abundance of diatoms were low. Conversely, cluster 4 was characterized by the survey sites of spring mostly and consisted of points of low TDI, even though total nitrogen was high. Considering that most of the created wetlands had the reduced inflow and outflow, the increased flow rate in the summer lowers nutrient values in autumn, and the species number and abundance of benthic diatom decreases due to the increase of turbidity, which reduces the light penetrations to the substrates. On the contrary, the TDI value is low in spring because the low water level causes insufficient substrate surface to the benthic diatoms, and it is too early for the establishment and development of saprophilous species. Although various studies have used TDI as an indicator for evaluating the habitat environment and water quality, it is not a good evaluation indicator in this study since the nutrient concentration in the wetlands mostly high as they have a low flow rate and are close to the stagnant area. Nevertheless, additional periodic surveys that comprehensively reflect the fact that the summer rainfall and inflow/outflow regulating function might affect the species diversity and distribution of benthic diatoms are necessary.

This study explored the architectural nature, the thought reflected in the place and the 'meaning-landscape' characteristic of a place, to where a retired scholar had lived. The object of the study is the Maechun-Byulup Toesu-jeong wonlim, which consists of a summer house and a garden forest. The results of the study are as following. Toesu-jeong wonlim is located at Daejeong-ri, Sannae-myeon, Namwon-si. It had been built by Maechun Park Chi-Gi in 1870 for his residence after retirement. It is a villa type pavilion and a garden forest which have Banseondaegi(伴仙臺記), Banseondae-10-yeong, Toesu-jeong(退修亭) Sangryangmun, a writing dedicated when putting up the ridge beam of a wooden house), Toesu-jeong Wonwun Byeongsoseo, hanging boards and tablets with poems written on them. In the Toesu-jeong wonlim, there are various 'meaning-landscapes' such as the Maechun-Byulup, Banseondae, Yabakdam and Simjinam together with engraved calligraphy related to the landscaping culture. It is also possible to find the remains of beautiful engraving on the stones and woods at Goksoo Yoogeo(曲水流渠) that suggest the banquets they had while discussing the elegant tastes and appreciating the landscape. The Toesu-jeong wonlim consists of the Toesu-jeong area(a pavilion), the Gwanseon-jae area(a shrine) area and the Gyejeong area(a garden with a brook) area. The pedantic 'meaning-landscape' elements, as the residence of retired scholar who spent his remaining life with elegant tastes, and the expertise of Maechun Park Chi-Gi, as a landscaping architect who built a villa and a garden forest in the motif of a Taoist hermit, can be extracted through the Banseondae-10yeong. The Banseondae-10yeong is the first Toesu-jeong poem and consisting of the Samseon-dae, Sejin-dae, Samcheong-dam, Yabak-dam, Samseo, Takgeum-dam, flat stones, caves, stone sculptures and harvest. The existing vegetation and plants in the Toesu-jeong wonlim are; natural pine forest in the rear garden, zelkova trees, wild cherry trees, apricot trees and pine trees bent to the waterfront direction. Except some ornament-species and shielding-species such as the poplars, most of current trees and vegetation keep the shape of the original Toesu-jeong wonlim landscape.
