Ceratopteris thalictroides is a semi-aquatic fern with a circumtropical distribution. Because this species is designated internationally on the IUCN Red List as requiring at least some concern, Korean populations are of great concern for the species' long-term survival, as they are at the northern limit of the species distribution. To establish an effective conservation strategy for those populations at the genetic level, we used the Mi-Seq platform to develop three sets of 25 polymorphic microsatellite markers for C. thalictroides, which is endangered in Korea. In populations sampled from Busan and Gochang, the number of alleles ranged from 2 to 13 (average of 5.64), and plants presented an expected heterozygosity of 0.000 to 0.860. These markers will be useful for evaluating the genetic status and conserving Korean populations of C. thalictroides more effectively.
The term "conserved remains" refers to cultural remains that are preserved in accordance with the valuation of buried cultural properties when important remains are recognized in rescue excavations during construction work. South Korea's rapid economic growth and ensuing land development over the past few decades compelled a sharp increase in the number of rescue excavation cases, and, naturally, of conserved remains. Today, an increasingly large number of conserved remains have raised issues, including those concerning land expropriation as well as the management and utilization of such remains, but no clear solutions have been proposed. This study attempts to propose plans for improvement based mainly on the recognition of institutional issues rather than technical issues related to the conservation of cultural remains. This is because the identification and review of institutional deficiencies must be prioritized in order to efficiently manage conserved remains with limited resources and manpower. Among many possible proposals to demand improvement of conservation policies, one that must first be examined under the current system is the rapid transition, or review thereof, of "conserved remains" to "designated cultural properties." Unlike designated cultural properties, conserved remains are merely a temporary means of conservation, because they lack regulations for follow-ups subsequent to preliminary measures. Naturally, deferring the definition of relics as "conserved remains" for extended periods causes numerous problems. Measures to resolve such problems may include establishing a legal system to manage conserved remains at a level similar to designated cultural properties or seeking ways to improve management under the current system. This study focuses on areas where institutional improvement for conserved remains is possible by methods other than through the rapid transition to designated cultural properties and presents several proposals. Currently, conservation measures are divided into three categories: on-site conservation, relocation conservation, and record conservation. This study reclassifies these categories from three into four categories. On-site conservation includes only two categories: conserved remains and the newly-proposed soil-covered remains. Two remaining categories, the relocation conservation remains and the record conservation remains, are presented as classifications in which development projects are possible, and they are presented as alternative conservation types that contrast with on-site conservation. Unlike conserved remains, soil-covered conservation presented as a new category in which development projects are possible.

Some of the metal cultural heritage that make up a considerable proportion of Korea's cultural heritage have been installed and displayed outdoors due to their own functions, roles, and scale. Therefore, more diverse and complex damages can occur outdoors than they are in a stable environment. Therefore, it is necessary to combine accurate diagnosis and systematic survey methods in order to utilize basic data obtained from research results as data for the long-term and continuous conservation management as well as to do the research to diagnose the conservation status of outdoor cultural heritage. The clepsydra(hereinafter referred to as Jagyeongnu) of Changgyeonggung Palace, the National Treasure has been installed and displayed outdoors since it was manufactured. Though regular conservation and maintenance of the Jagyeongnu have been carried out, damage still occurred. Therefore, the scientific research on Jagyeongnu to diagnose the state of conservation was conducted prior to the full-scale conservation treatment. First, the state of conservation was investigated with an examination of basic data, macroscopic inspections and past records of repair history according to the purpose of the research. More detailed examinations were also conducted through the 3D scan, surface pattern investigation, and color difference analysis, and the analysis on materials and contaminants were conducted through P-XRF, FT-IR, and Py-GC/MS. The scientific research reveals that squalane and silicone oil have been applied in the past for conservation treatment and directly exposed to outdoor environmental factors, which caused damage to Jagyeongnu and contaminants such as dust adhered thickly to its surface, accelerating severe damage. A greater incidence of damage was found around the part with relatively high exposure effect, which corresponded with the tendency identified by grouping color difference data. As a result of integrating various research methodologies to diagnose the state of conservation and secure basic data, the causes and types of damage were identified. Furthermore, the process of obtaining digital data to be utilized in various ways, and the color difference analysis presenting visible damage as scientific data and identifying the tendency of damage patterns were confirmed to have been effective.
This study was conducted to investigate and analyze the designation status of the Local Wildlife Conservation Ordinance for the conservation and management of wild fauna and flora, and to elucidate the problems and improvement directions. We compared and analyzed the provisions of the wildlife conservation ordinance of 17 regional local governments. After that,the designation status of Wildlife Protected by City/Do was investigated and the appropriateness was confirmed based on guidelines and laws. The ordinances related to wildlife were enacted in all municipalities, and provisions such as selection criteria, protection measures, and act limitations were commonly reflected. The provisions were varied depending on the characteristics of each local government, including details of flag species, the addition of species in the restoration promotion plan as criteria for selection and provision of protection and restoration of habitats. Since 2006, when the wildlife protected by City/Do designation and protection guidelines have been established, the protected wildlife have increased sharply, and there has been newly designated regional local government within the past one or two years. However, in some local government, protected wildlife has been designated for more than 10 years, and there are many that do not meet the selection criteria. Therefore, more scientific and objective selection criteria and methods should be constructed for the selection of species suitable for the purpose of the Wildlife protected by City/Do.

For the preservation and efficient content sharing of 5 volumes (2,866 pages) of Yu Kil-Chun's book published in 1971, which provides an important collection of data for the study of modern Korean history during the late 19th century (enlightenment period of Joseon dynasty). The books were purchased and its preservation status investigated and documented electronically by scanning for permanent preservation of content and to determine the condition of preservation at the time of documentation. The degree of deterioration and damage, such as discoloration, hardening, breakage, and damage in these 50 years old modern printed books was quantified through image analysis and made attempts to visualize the damaged areas. It was observed that the degree of deterioration and damage depended on the material and the surface condition of the paper used, the degree of exposure to light, and the storage environment. The comparison of the preservation status at the time of the photographing (or scanning) and judgment as to whether or not the image under investigation was artificially modified was accomplished by comparing the electronically documented images of Seoyugyeonmun (西遊見聞) in Volume 1 of Yu Kil-Chun's works with images provided on other websites. Practical problems encountered while considering the effective preservation of electronically documented data and publicly sharing it, in the course of this study, with other academic researchers around the world were also summarized.
If the plant genetic resources and information-sharing systems held by arboretums worldwide are effectively utilized, it is believed that a conservation system for plant diversity in the currently inaccessible North Korean region could be established. This study was conducted to review the scientific names of plants native to North Korea but not to South Korea and to assess the status of genetic resources held in domestic and international arboretums. To compile a list and status of North Korean plant's genetic resources, updated checklists of vascular plants in Korean Peninsula and online plant information databases were consulted to compile synonym, distribution range, and other related information. A total of 486 taxa (449 species, 13 subspecies, 21 varieties, 1 forma and 2 hybrids) from 236 genera and 64 families, representing 12.34% of the total native flora of the Korean Peninsular were presented in the North Korea plant list, and the presence of rare, endemic and northern lineage species was confirmed. It was found that 384 taxa from 190 genera, 53 families of North Korean plants are held as genetic resources in 333 arboretums and plant research institutions across 46 countries and 5 continents worldwide. This study is expected to contribute to the construction and application of a species list for plants native to the Korean Peninsula.
As the tangible evidence, documentary art records are permanent records to reflect the historical, symbolical, cultural and artistic value. Also, documentary art records are related with mission fulfillment of public institution and it is documentary with administrative, cultural and artistic values as the works of documentary production and application of the administrative image. "The public records management law" was the first time that administration documents were incorporated and in the act No. 3 of administrative records management, the preservation and management system of documentary art records became legislated. The management of documentary art records are difficult to categorize only by the reflect of characteristics or materials. Because documentary art records are collected in many ways and made with materials. It needs to be collected with many informations on basic materials and with the appropriate conservation and management category. Documentary art records do not have lots of demands but the level of consciousness is improving and the possibility of opening to public is increasing for improvement with the right to know. In near future, the documentary art records will be used for the interpretation of historical and cultural preservation and modern cultural heritage could have the value as it is expected. Primarily to prevent deterioration on documentary art records the standard survey card should be made to categorize the damage rate and to check the status on each documentary art records. In addition, establishing a systematic management plan for various documentary art records are needed with the training of professionals for the conservation of documentary art records.

Borimsa was first built by Wonpyo, the great Buddhist priest of Whaum branch, in the year of 759 A.D. And Later the priest Chejing converted to Zen Buddhism in the year of 858 A.D., Borimsa got the central status of the Zen Buddhism, and was so prospered during the Chosun period. This research is the conservation treatment of the Buddhist literatures and the "Wolinsukbo" Vol.25, discovered in 1995 from the Four Devas of Borimsa, Buddhist Temple at Jangheung County, in the viewpoint of the bibliography. "Wolinsukbo" Vol.25 is consist of 142 pages and the size is of 22cm width, 32.3cm of length, and 2.8cm of depth. And also have the five-pinned eye revisor. The pre-conservation condition of this book was partly spotted by the permeated rain, and the cover pages being deeply spoiled. The conservation treatment was done in the sequences of 1) 1st linsing, 2) repairing and correcting, 3) 2nd linsing and conservation, 4) cutting and binding. The post-conservation condition of "Wolinsukbo" Vol.25 is of, 9 pages including covers are added, total 151 pages, and the size being 22.5 cm width, 32.7cm of length, and 3.2cm of depth.

Environmental Conservation Value Assessment Map (ECVAM) is the class map to divide the national land into conservation areas and development areas based on legal and ecological assessment criteria. It contributes to enhancements of the efficiency and the scientificity when framing a policy in various fields including the environment. However, it is impossible to understand the multiphase vegetation structure as data on judging the national forest class in ECVAM are restricted to areal information of Ecological Nature Status, Degree of Green Naturality and Forest Map. This point drops the reliability of ECVAM. Therefore we constructed vegetation information using LiDAR (Light Detection And Raging) technology. We generated Biomass Class Maps as final results of this study, to introduce the new forest assessment criterion in ECVAM that alternates or makes up for existing forest assessment criteria. And then, we compared these with Forest Map and Landsat TM NDVI image. As a result, biomass classes are generally higher than stand age classes and DBH classes of Vegetation Map, and lower than NDVI of Landsat TM image because of the difference of time on data construction. However distributions between these classes are mostly similar. Therefore we estimates that it is possible to apply the biomass item to the new forest assessment criterion of ECVAM. The introduction of the biomass in ECVAM makes it useful to detect the vegetation succession, to adjust the class of the changed zone since the production of Vegetation Map and to rectify the class error of Vegetation Map because variations on tree heights, forest area, gaps between trees, vegetation vitality and so on are acquired as interim findings in process of computing biomass.

The rapid increase of naturalized plants causes disturbance of the ecosystem. The purpose of this study is to identify the reality of naturalized flora in Jeolla-do. A total of 830 sites were studied in 2016. These naturalized plants consisted of 189 taxa in total, belonging to 38 families, 116 genera, 181 species, 2 forms and 6 varieties. According to the results of the analysis based on place of origin, 75 taxa were from Europe, and 59 taxa were from North America. According to the analysis of the ecological characteristics, compositae had the highest diversity among 31 families, with 44 taxa, followed by Gramineae, with 24 taxa, and Leguminosae, with 10 taxa. Naju-si had the highest diversity among 36 counties, with 77 taxa. This study identified 37 (Jeollanam-do) and 30 taxa (Jeollabuk-do) not listed in the preceding literature in Jeolla-do. We found a lots of differences between flora's databases of previous studies resulting from the naturalized plant definition.
