Natural Monument is a designated cultural property as part of the country. According to Article 2 of the Cultural Properties Protection Act, a national, ethnic and global heritage artificially or naturally formed, with a great historical, artistic, scientific and landscape significance is defined as a cultural heritage. Animals, plants, topography, geology, minerals, caves, biological products and special natural phenomena, having a great of historic, scenic and scientific value, are defined as the monument. According to Article 3 of Cultural Properties Protection Act, the conservation, management and utilization of National Heritage should be kept intact in its original form. So, Natural monuments are managing as retained its original form under the Basic Principles of current law. The highest population of coniferous tree in natural monument plant is ginkgo tree including 22 objects, followed by pines, junipers that order. And in case of broadleaf tree, there are zelkova trees, retusa fringe trees, pagoda trees, cork oaks, silver magnolias and etc. There are many of reported efficacy in available natural monument plants. The efficacy of plant species on pharmaceutical like anti-cancer, anti-diabetic, anti-obesity, antioxidant activity, neuroprotective, improves cholesterol, anti-inflammatory, liver protection and anti-bacterial efficacy, on cosmetics and beauty like the inhibiting formation of skin wrinkles, whitening effect, variety of materials and the efficacy of the proposed utilization of its various papers and etc have been widely reported. Before the Nagoya Protocol enters into force, the future role of the National Research Institute for Cultural Properties Administration of Cultural Heritage should be obtain a legal right to manage the social, cultural and national natural monument with emotional value to the plant genetic resource as a natural monument efficient ways to study and preserve traditional knowledge biological resources by securing a claim to the sovereignty of the material will be ready.

Studies on the Korean cave fauna were reviewed during the last seven decades since the first record of Antrokorean gracilipes Verhoeff, 1938. The cave animals have been reported by only 112 papers, 16 repoyts and ten books. In the results, a total of 257 species is recorded representing four phyla, ten classes, 31 orders, and 94 families, and also the holotype localities of 87 species are recorded from 36 caves and four wells in Boron. Arthropods are predominant consisting of 241 species (93.8％), and true spiders (Araneae) are a most diverse group with 97 species (37.7％) including 21 Korean endemic species belonging to 29 families.

This paper reviewed a total of eight sites in Vietnam inscribed on UNESCO's World Heritage List. The sites include the five cultural heritage sites(the Central Sector of the Imperial Citadel of Thang Long, Citadel of the Ho Dynasty, My Son Sanctuary, Hoi An Ancient Town, and Complex of Hué Monuments), two natural heritage sites (Ha Long Bay and Phong Nha-Ke Bang National Park), and one mixed heritage site (Trang An Landscape Complex). All these sites are situated in the northern and central areas of the country, and no inscribed site exists in the south. The two natural heritage sites and the Trang An Landscape Complex, a mixed heritage site, feature a typical Karst topographic landscape with limestone caves, cliffs, stalactites, and underwater rivers. The four cultural heritage sites as well as Hoa Lu of the Trang An Landscape Complex mainly consist of remains of the citadels of the capitals of ancient Vietnamese dynasties from the northern region. Due to the complex political situation in the aftermath of the long Vietnam War and the subsequent unification of the country, the Vietnamese government has been giving priority for inscription on the World Heritage List to sites with historical legitimacy in the northern region. It is hoped that the Vietnamese government will pursue more integrated cultural policies in the future that can help reduce north-south regional disparities.

About 30 limestone caves have already been developed at the basin of the River Dong. baekyong Cave, Hwaam Cave, and Jeolgol Cave are of great worth, not noly as a matter of study, but as a matter of the tourist resources they develop. Among them Baekyong Cave is the best. I'm going to give a full detailed account of cave deposits and cave phenomena focused on its view to preserve the looks of Baekyong Cave by analyzing the speleothem of Baekyong Cave and cave system scientifically and systematizing them. Baekyong Cave, Natural Monument Ho. 260, is on the verge of being submerged. Peculiar things in Baekyong Cave are 1) pseudo stalgmite 2) anthodites 3) erratic stalagmites 4) cave shield 5) lost river 6) cave flint 7) pit fall but I have also mentioned general and related matters.

It is well known that actinomycetes would be useful for screening of biologically active compounds. Not only to isolate diverse actinomycete strains but to ferment those strains effectively would be important. Seven hundred and forty six strains were isolated from Cheju province, 216 strains were from Chungnam province, 158 strains were from the natural caves at Chungbuk and Kangwon provinces and 202 strains were from Chungwon area at Chungbuk province. All of these 1,322 strains were fermented on a small scale using two different media and tested for their antimicrobial activities against four bacterial strains and one yeast strain. As the result, 12.3% of those isolates were active against Staphylococcus aureus KCTC 1916, 7.6% were Staphylococcus aureus KCTC 1928, 3.9% were Escherichia coli KCTC 1924, 3.0% were Candida albicans KCTC 1940, and 2.2% were Salmonella typhimurium KCTC 1926. About 40% of those isolates showed antimicrobial activities at both two media but the others showed at either one. According to the genus of isolated strains, Streptomyces and Micromonospora showed activities with higher frequencies than others.

During a comprehensive investigation of indigenous prokaryotic species in Korea, a total of 46 bacterial strains assigned to the classes Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, and Epsilonproteobacteria were isolated from a diversity of habitats including freshwater, seawater, brackish water, ginseng soil, plant roots, natural caves, and tidal flats. Based on their high 16S rRNA gene sequence similarities (>98.7%) and formation of strongly-supported phylogenetic clades with the closest type species, each strain was assigned to an independent, predefined bacterial species. Since there were no published or official reports regarding the isolation of these 46 species in Korea, here we report them as new species to Korea: 34 species in 14 families in the five orders of Alphaproteobacteria, 10 species in five families in the three orders of Betaproteobacteria, one species of Deltaproteobacteria and one species of Epsilonproteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.

The establishment of a complete geological model that includes information about all the various components at a site (such as underground structures and the compositions of rock and soil underground space) is difficult, and geological modeling is a developing field. This study uses commercial software for the relatively easy composition of geological models. Our digital modeling process integrates a model of Jeju Island's 3D geological information, models of cave shapes, and information on the state of a road at the site's upper surface. Among the numerous natural caves that exist in Jeju Island, we studied the Jaeamcheon lava tube near Hallim town, and the selected site lies below a road. We developed a digital model by applying the principles of building information modeling (BIM) to the cave (CaveBIM). The digital model was compiled through gathering and integrating specific data: relevant processes include modeling the cave's shape using a laser scanner, 3D geological modeling using geological information and geophysical exploration data, and modeling the surrounding area using drones. This study developed a global-scale model of the Hallim region and a local-scale model of the Jaeamcheon cave. Cross-validation was performed when constructing the LSM, and the results were compared and analyzed.

This paper examines the lava tubes designated as a natural monument in Jeju Island, and then makes the several suggestions for conserving and managing them. The cave entrances should be scientifically and strictly managed to prevent the deterioration, and to preserve the interior ecosystem, of the lava tubes. The land use and vegetation of the ground surface over the lava tubes should be also systematically managed; the destroyed sand dunes must be recovered for the development of speleothem in the lava tubes, and the plants with deep roots must be removed for the prevention of ceiling collapse. The provincial authorities should manage the ground surface over the lava tubes as a public land to remove the factors threatening the stability of the lava tubes. Since the roads crossing the ground surface are likely to cause the collapse of the lava tubes, new roads bypassing the caves need to be constructed, and warning signs should be also installed at the traverse points. A monitoring system on the cultural properties protection area over the lava tubes could be effectively established by encouraging residents to participate the conservation program of lava tubes. Since the falling blocks from ceilings have been usually observed in the lava tubes, it is urgent to examine their stability. In particular, the dangerous sections must be continuously monitored for taking a quick measure against the collapse. The air environments of lava tubes need to be scientifically analyzed based upon the long-term observations. The lighting equipments must be improved to minimize the green pollution in the lava tubes open to the public. The numbers of visitors should be also controlled to prevent the destruction and contamination of lava tubes caused by a large number of visitors.

This study seeks what kind of factors influence to locate dwellings and to establish scenic spots in nature by a case study focused on a meandering stream. The study specially concentrates on the interrelationship between both residences and beautiful sceneries and a meander cut-off-area that reveals a special topographical characteristics, located at Samji village in Youngyang-eup, Youngyang-gun, Koungsangbuk-do. The meander cut-off area, developed at the middle or upper reaches of a river, often makes up specific landscapes such as precipitous cliffs, sheer cliffs and caves. And the area where is specially created by sudden change of flow due to erosion ;perceived by the cut surface to be the most beautiful scenic spot. These beautiful landscapes were used to be called as Dae, Dam or Gul and managed by Confucian scholars who enjoy refined taste and devote themselves to the study in nature. Moreover, the Ku-Hado-literary means the area of ex-flow-made the scholars' lving with a well prepared basis for agriculture where supplied a cornucopia of organic matters and water. The merit of agriculture made it possible that the scholars became economically independent, and the fact might be the essential point why the meander cut-off area took noticed. Actually, Cho-family has been in Smaji Village for generations, producing a large number of scholars and keeping the actual power of the region. The physical shape of the meander cut-off area, cozily surrounded by mountains, is considered as a good place for the dwelling due to the influence of traditional sight of view for location and P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world. It is a fruit in it own way that we could find the ancestors' discernment and wisdom from this study, who have lived their lives adapting themselves to the given natural environment and also utilizing the nature wisely. But this is a current-argued study on the meander cut-off area. Follow-up studies have to be continued about the landscapes of the meander streams and the meander cut-off areas scattered all over the country except Samji Village and draw the characteristics from the comparative analysis.

Within a comprehensive, widescale investigation of indigenous prokaryotic species in Korea, 29 bacterial strains in the phylum Bacteroidetes were isolated from diverse environmental habitats that included soil, plant roots, natural caves, tidal flats, freshwater from lakes, and seawater. Based on their high 16S rRNA gene sequence similarities (>99.1%) and the formation of robust phylogenetic clades with the closest type species, each strain likely belonged to an independent and predefined bacterial species. There are no publications or official reports of the isolation of these 29 species in Korea. Our study provides strong evidence that seven species in three genera in the order Cytophagales, 15 species in 13 genera in the order Flavobacteriales and seven species in five genera in the order Sphingobacteriales, all within the phylum Bacteriodetes, are new reports of bacterial species in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.
