  • The increase in human use and activity in the oceans is leading to marine pollution and habitat destruction. As a result, in particular, marine animals with a long life cycle and small population are threatened with extinction. Thus, the Korean government designated 11 artificial habitats, such as aquariums and marine museums, as Ex-situ conservation institutions to preserve endangered marine life in 2010. However, studies on the significance and economic value of Ex-situ conservation institutions providing marine life conservation services have not been conducted. Thus, the purpose of this study was to estimate the public's quantitative support for the operation policy of Ex-situ conservation institutions, which is a management method for the protection and propagation of marine animals in Korea. To achieve this, the economic value of the marine animal conservation role of the National Maritime Museum was estimated, operated as an Ex-situ conservation institution for the preservation of green turtles in Korea. By using the representative non-market valuation method for public goods known as the contingent valuation method (CVM), the economic value of the Ex-situ conservation institution (National Maritime Museum) was estimated at approximately 41.8 billion won to a maximum of 78.1 billion won. The results of this study can be applied as basic data for marine animal management policymakers in establishing efficient management plans for endangered marine animals in Korea's coastal waters.

  • This study conducted conservation treatment of a briefcase used by a soldier who fought in the Korean War as a member of the United Nations Forces. The zooid characteristics of its main material, leather, were analyzed in collaboration with the researchers at the National Palace Museum of Korea who have conducted relevant research. A plan for conservation treatment was established based on the results of this analysis. The briefcase was made of leather with a wooden frame. The many densely arranged tiny pores in different patterns on the leather's surface suggests calf leather. The wooden frame and leather had suffered deformation over long years of deterioration and thus required conservation treatment to enhance their structural stability. The conservation treatment began with the removal of contaminants from the exterior and interior of the briefcase. The stiffened leather was softened through humidification, and torn or separated areas were restored using cowhide glue. It is expected that the results of this conservation treatment and analysis of the leather material will serve as useful sources for basic research on leather items as well as wartime and military items.

  • The composition analysis of mural pigments at Daeungjeon Hall of Bongjeongsa Temple(Treasure No. 55) and ancient tomb with mural pigments in Goadong(Historic site No. 165) were carried out by XRF and MXRD. The analytical result showed that red pigments were Red Lead($Pb_3O_4$), Cinnabar(HgS) at Daeungjeon Hall of Bongjeongsa Temple and Cinnabar(HgS) in Goadong. The main composition identified in white pigments were Lead Carbonate Hydroxide[$PbCO_3{\cdot}Pb(OH)_2$]. Green pigments were basic copper chloride[Paratacamite $CuCl{\cdot}Cu(OH)_3$], celadonite[$K(Mg,Fe,Al)_2(Si, Al)_4O_{10}(OH)_2$] at Daeungjeon Hall of Bongjeongsa Temple and were basic copper chloride or basic copper carbonate in Goadong. Therefore it proved that mural pigments painted in use the mineral materials.

  • Silica-based inorganic fillers for restoration of iron objects have been used for the reduction of thermal expansivity and the improvement of melt flow index. However, the higher the amount of filler is applied, the more degradation of mechanical properties and the yellowing occur, which could cause retreatment of the objects with adding stress to them. Thus, research on not only the quantification of a mixture of resin and filler but also the yellowing should be emphasized. Experiments on mechanical properties were carried out with a silica-based light filler, Micro Shell as a comparison group. The results of the experiment showed Micro Shell reduced the number of occurrences of the yellowing by 34% compared to existing fillers. The value of adhesion and specific gravity was also improved depending on the filler amount. The results of this research indicate the possibility of using Micro Shell as a new filler.

  • Limestone areas are sedimentary rock outcrops consisting of calcium carbonate created several hundreds of millions of years ago by calcium-secreting marine organisms and subsequently lifted above sea level by tectonic movement. Limestone areas support very high levels of endemic species of plants and are recognized as biodiversity areas with much biological information. The purpose of this study is to devise a strategy for the comprehensive conservation of the vegetation of limestone areas through analyses of the floristics and plant species compositions in ten limestone areas on the Korean Peninsula. The results of 153 field surveys from April of 2010 to October of 2016 identified 1,202 taxa in total, representing 1,096 species, 18 subspecies, 84 varieties, 2 forms, and 2 hybrids in 530 genera and 133 families. Among them, 55 taxa were endemic plants to Korea, and 38 taxa were red data plants. The floristic target plants amounted to 102 taxa, specifically 27 taxa of grade V and 75 taxa of grade IV. In all, 121 alien plants were recorded in the investigated area. Calciphilous plants amounted to 102 taxa, specifically 14 taxa of calciphilous indicator plants, 30 taxa of superlative most calciphilous plants, and 58 taxa of comparative more calciphilous plants. A cluster analysis showed a high degree of similarity between sites that are geographically adjacent with similar habitat environments. Limestone areas also supported groups distinct from those in non-limestone areas, demonstrating the specificity of limestone flora. Plant geography approaches therefore appear to be crucial to gain a better understanding of the level of biodiversity in limestone areas, not only at the interspecific but also at the intraspecific level. These results highlight the importance of protecting limestone habitats to preserve not only their interspecific but also the intraspecific diversity, which is highly threatened.

  • Designated as a national intangible cultural asset, the fish weir is a traditional fishing method and was a leading fishing tool in Korean coastal fishery. As the littoral sea area fishing vessel fishery developed since the 1970s, traditional fishing methods including fish weirs began to decline. The fish weir has been passed down in the form of tools such as fish weirs, stone weirs, and bamboo weirs. In Namhae-gun and Sacheon City in Gyeongsangnam-do, anchovies are caught using bamboo weirs. A basic bamboo weir consists of a fish trap(balgong), a space where fish gather together, and a V- or U-shaped wooden fence(halgaji) that helps fish come inside the fish trap. Its fishing method is to catch fish that have come to the coast during high tide alongside those are stuck inside fish traps(balgong) with nets or scoop nets. This paper examined the process of passing down traditional fishing methods through a comparative analysis of the bamboo weir structures and fishing methods in the Namhae and Sacheon regions. First, the historical process of assembling the current bamboo weir structure was analyzed. The bamboo weir, a fishing tool, appears to have combined the features of past weirs and fish weirs based on the Jijok Strait and Samcheonpo Strait. Next, this paper examined the structure and fishing method of the two types of bamboo weirs made with a circular or square fish trap(balgong) where fish gather. Through this analysis, this study examined the lives of fishermen who have adapted to their natural environment and actively utilized obtainable resources(materials), and then changed the traditional fishing method of bamboo weirs and developed them into an appropriate technology. Lastly, a new value attributed to anchovies caught using bamboo weirs was analyzed. This new value extracted from better bamboo weir anchovies works as a mechanism to uphold the tradition of anchovy-catching bamboo-weir fishing, which produces a smaller amount of anchovies compared to other methods of anchovy fishing. In this way, bamboo weir fishing has been passed down as a result of its differentiated aspect of producing better anchovies than those produced with other fishing methods, as well as the historical aspect of it being a traditional fishing method.
