The purpose of this study was to reduce the drop out rates and enhance the quality of docent training education program in the Nature Heritage Center by providing educational services appropriate to the docents' needs based on the docents satisfaction survey. In this research, we conducted the survey to analyze the importance-satisfaction of natural heritage docent satisfaction in natural heritage docent training programs. The subjects of this survey were 30 docent in Natural Heritage Center. To develop a questionnaire, a factor analysis was conducted, as a result, 6 factors and 22 questions were presented. They are 'curriculum and instruction', 'advice for docent', 'educational environments', 'administrative services', 'support for docents', 'docent life'. The results of t-test, there was a significant difference between importance and satisfaction of the every 22 questions, the mean score of satisfaction(M=3.87, SD=.08) was lower than that of importance(M=4.10, SD=.20). According to ISA, the items located in "concentrate here" were deduced. They are 3 items from administrative services, device for docent, curriculum and instructions. To put in concretely, They were 'lecture content(subject)', 'teaching method', 'service attitude of personnel', 'interest in a docent' Based on these results and descriptive responses from the docents, the strategies for docent satisfaction in natural heritage docents training programs were suggested.
Among the UNESCO World Heritage Sites, the proportion of natural heritage to cultural heritage is relatively small. In 2007, the "Jeju Volcanic Island and Larva Tubes" was the first one that was designated as an UNESCO World Natural Heritage Site in Korea. The growing Korean geological heritage condition and conservation case studies on management of the geological heritage were examined in this study. Furthermore, the purpose of this study is to show future driving strategy for conservation and improvement plan on our geological heritage. Natural Monuments as a state-designated natural property and Geoparks as a new application system for geological heritage are important to conserve our geological heritage. Public engagement through establishment of visitor centers is definitely needed to improve education and promotion. The study includes field investigation for the "Wadden Sea", an World Natural Heritage Site for a mud flat, interviews with staffs and experts who are responsible for investigating and managing the site. Three factors can likely be attributed to its successful management and conservation policy for the "Wadden Sea". First of all, there is an operation for integrated management system and joint secretariat for research and monitoring. Next, researchers invigorate the visitor centers for promotion and education on geological heritage. Finally, experts and staffs implement various research topics and projects based on a long-range plan. The study was carried out to evaluate the present condition of our geological heritage and to make a proposal as a policy to improve value and conserve them. In conclusion, this study provided future discussion that may help researchers to make a decision on long-term policies for the geological subject of Korean natural heritage.
This essay explores the problems with applying the concept of "original form" to natural heritage when it is based on originality and diachronic, historical period. It also suggests an alternative perception that the concept of "original form" can be considered based upon "integrity". First, the conceptual framework for applying the concept of "original form" falls into three types: one that centers on the time point at which heritage originated; another that respects the diachronic characteristics of the concept of "original form"; and the last that bases original form on a particular time after the heritage originated. Second, the national policy for the conservation of natural monuments and scenic sites stayed at the level of consulting the Decree on the Preservation of Treasures, Historical Remains, Scenic Sites, and Natural Monuments of Joseon, under Japanese colonial rule. And after the legal framework was established through enacting and proclaiming of the Cultural Heritage Protection Act in 1962, 564 cases have been designated as natural monuments. Third, the natural conservation movement, the first national policy for natural heritage, was initiated from the heritage field, but the Environment Ministry subsumed all nature-related policies and ever since the heritage agency (Cultural Heritage Administration) has implemented only heritage policies regarding "cultural" heritage. The present state of the coexisting policies about the natural heritage by the Environment Ministry and the Cultural Heritage Administration resulted in leading the public confused about official terms and main policy agency of natural heritage. Fourth, the difficulty of applying the concept of "original form" to natural heritage stems from the fact that natural heritage is inherently distinct from cultural heritage, which is placed at the center of the heritage policies implemented by the heritage agency. In addition, natural heritage, similarly distinct from the overall natural environment, has evolved in a way that incorporates human culture and thus diversely includes characteristics of originality, diachrony, and historical period. Under these circumstances, an incorporative, professional approach is required rather than independent approaches for each type of natural heritage. In conclusion, this essay suggests that issues related to the restoration of original conditions of natural heritage should be resolved through the application of the "integrity" concept by restoring "the characteristics of an object or a place that imbue it with meaning and value," with consideration given to efforts for alleviating logical contradictions within the concept of "original form" through the preparation of standards and guidelines for the restoration of original condition.
This paper proposes a mobile augmented reality mashup for cultural heritage sites such as natural monuments. Several benefits of mobile augmented reality solutions are ideal for preserving and protecting cultural heritage sites. By presenting mobile augmented reality mashup scenarios and mobile mashup framework, we introduce how user-generated multimedia contents can be added. We present two scenarios of Mashup Viewer and Mashup Maker. In Mashup Viewer mode, visitors can create new AR contents using mashup tools for memo, Twitter, images and statistical graphs. In Mashup Maker mode, other visitors also can view the user-generated multimedia AR contents using QR codes as access points. To show feasibility of our approach in mobile platforms, we compare several detection algorithms on PC and mobile platform and report on deployment of our approach in a natural monument museum. With our proposed mashup tools, visitors to the cultural heritage sites can enjoy default AR contents provided by the site administrators and also participate as active content producers and consumers.

Paper relics, which are made of natural ingredients, are more likely to be damaged by a compendium of complicated causes (e.g., physical, chemical, and biological causes) rather than by a sole cause. In December 2009, Culture Heritage Conservation Science Center discovered several damages in paper relics related to Chungmugong Yi Sunsin, and requested for conservation treatment from the Hyeonchungsa Shrine office. By conducting a comprehensive research to determine the damage level of each artifact, the center was able to establish a proper conservation method, and for two years after its completion of such research in 2010, it has been conducting treatment. This study suggests the proper ways to select adequate conservation treatment based on the type of paper relics - Documents and Books - through the case of artifacts related to Chungmugong Yi, Sunsin. Even though the conservation treatment on paper relics can suppress damaging speed and prevent another damages, it is impossible to stop aging process of relics. Therefore regular inspection is essential for prevent second damage.

Following the earthquake that shook the city of Gyeongju, Korea, in 2016, it became apparent that research on the safety of cultural heritages against the seismic hazards is necessary in Korea. Predictions of how historically significant stone pagodas would behave the earthquakes anticipated in near future, which are the subject of this study, is also required. In this study, the dynamic characteristics of 15 cultural heritage designated stone pagodas of Korea were investigated, including natural frequency and damping ratio, and the stiffness of the stone material and its contact area were determined using eigenvalue analysis by assuming the stone pagodas to be multi-degree-of-freedom structures. The results of this study enable the structural modeling of stone pagodas using a finite element analysis program and the method is expected to be useful in assessing the structural safety of stone pagodas against vertical loads as well as lateral forces, including earthquakes. Also, by identifying the dynamic characteristics of the structures, the results of this study can be utilized as a nondestructive testing method to determine the rigidity of cultural heritage structures and to identify inherent problems. The natural frequencies of the Korean stone pagodas were measured to be within 3.5~8.3Hz, excluding cases with distinct natural frequency results, and it was determined that the natural frequencies of the stone pagodas are influenced by various parameters including the height and joint stiffness of the structures.
The number of World Natural Heritage Sites is smaller than that of World Cultural Heritage Sites. As of 2010, the total number of natural sites was 180, which is less than 1/3 of all cultural sites. The reason why the number of natural sites is smaller can be attributed to the evaluating criteria of OUV(outstanding universal value). Only 9 fossil related sites were designated as World Heritage Sites among 180 Natural Sites. This study compares their OUVs including the academic value and characteristics of the 9 World Heritage Sites to provide data and reference for KCDC(Korean Cretaceous Dinosaur Coast) to apply as a World Natural Heritage Site. This study was carried out to obtain information and data on the Wadi Al-Hitan of Egypt which was designated as a World Natural Heritage Site. The study includes field investigation for whale fossils, interviews of site paleontologists and staff, and inspections of facilities. Three factors can likely be attributed to its successful management and operating system. First, there is a system for comprehensive research and a monitoring plan. Secondly, experts have been recruited and hired and professional training for staff members has been done properly. Finally, the Wadi Al-Hitan has developed local resources with specialized techniques for conservation and construction design, which matched well with whale fossils and the environment at the site. The Wadi Al-Hitan put a master plan into practice and achieved goals for action plans. To designate a future World Natural Heritage Site in Korea, it is important to be recognized by international experts including IUCN specialists as the best in one's field with OUV. Full-time regular-status employees for a research position are necessary from the preparation stage for the UNESCO World Heritage Site. Local government and related organizations must do their best to control monitoring plans and to improve academic value after the UNESCO World Heritage Site designation. As we experienced during the designation process of Jeju Volcanic Island and Lava Tubes as the first Korean World Natural Heritage Site, participation by various scholars and specialists need to be in harmony with active endeavors from local governments and NGOs.
Decay or large cavities inside trees are the main causes of trees overturning and broken branches, and structurally weakened trees are more vulnerable to strong winds and heavy snowfall. Recently, as strong winds and typhoons increase due to climate change, the damage to human life and property due to trees overturning continues to increase, and cultural assets are in a similar situation. In particular, old big trees are structurally vulnerable to external shocks such as strong winds and heavy snowfall. This study was aimed at providing a scientific basis for preventive protection measures by conducting a structural stability diagnosis of seven retusa fringe trees designated as natural monuments. For the structural stability diagnosis, tree risk assessment and internal tree defect measurements were performed. As a result of the tree risk assessment, the Retusa Fringe Trees in Sinjeon-ri, Yangsan and Gwangyangeupsu had the highest risk of broken branches due to weak branch attachment strength. As a result of the diagnosis of internal defects of cross sections of measured trees, there were suspected cavities or severe decay in all except two trees of the population of Retusa Fringe Trees in Pyeongji-ri. Natural disasters due to climate change are increasing, and the scale is getting larger, so it is very important to preemptively manage large old trees through scientific structural safety diagnosis to manage trees that are vulnerable to environmental changes.

This study started from the need to improve one of shortcomings of synthetic PVAc adhesives - potential physical harm and environmental hazards to the workers or their users. As a matter of fact, PVAc adhesives are currently mainly used because of their convenience and economy for the production of woodcrafts. The purpose of this study was to develop natural adhesives through research on natural adhesives in step with the current increase of societal attention to environmental friendliness and rapid surge in their demand in the face of such problems. So, the study attempted research on the bases to develop natural adhesives for woodcraft, using cellulose extracts from wood - natural adhesive material. The findings of the study were as follows. Firstly, natural adhesives showed the improved effect in the field of adhesive strength, a basic physical property by 0.2 - 4 times compared with the existing materials and the study confirmed they had the similar or stable pH value. Besides, they had good reversibility, demonstrating their basic physical property as a natural adhesive for woodcraft. While, their durability to ultraviolet ray degradation also showed an excellent result value being better by 1.5 - 8.5 times than the existing materials. The study expects natural adhesives with improved and better performances compared with the existing materials could be developed, if further research on adhesive strength, antibiosis, conservative property were to continue by developing refinery technology for cellulose extracts from wood and rendering the functionality to them.
