In recent times, sea level increasing caused by abnormal weather and global warming, sea-sand dredging and complex development causes various kind of erosion damages onto the coastal area in the world. The various types of erosion control and protection methods are applied but there are no signs of fruitful effectiveness. The PC concrete protection block for shore protection structure is practically installed in globally but most of structures in the present day became villainous because of bad accessability. In this study, hydrophilic revetments for control and protection of coastline erosion will be developed in order to make up for a faculty of the shore erosion protection block with better accessibility and excellent protection ability. Experimental measurements were researched to insure for the capacity and facility on reflection coefficient, overtopping volume, and overtopping height characteristics of newly developed shore erosion protection block in model tests. As the result, hydraulic model tests show much excellent than the general step block. Field tests were carried out also to verify through vegetative test on an affinity and construction work test of control-protection on coastline erosion with actual utilization. In the latter case, deposition of sand accumulation occurred in fairly short time at the established reaches and then we can be confirmed to utilize for newly developed block as the revetments for control and protection of coastline erosion.

Climate change is affecting the evolutionary trajectories of individual species and ecological communities, partly through the creation of new species groups. As population shift geographically and temporally as a result of climate change, reproductive interactions between previously isolated species are inevitable and it could potentially lead to invasion, speciation, or even extinction. Four species of abalone, genus Haliotis are present along the Korean coastline and these species are important for commercial and fisheries resources management. In this study, genetic markers for fisheries resources management were discovered based on genomic information, as part of the management of endemic species in response to climate change. Two thousand one hundred and sixty one single nucleotide polymorphisms (SNPs) were discovered using genotyping-by-sequencing (GBS) method. Forty-one SNPs were selected based on their features for species classification. Machine learning analysis using these SNPs makes it possible to differentiate four Haliotis species and hybrids. In conclusion, the proposed machine learning method has potentials for species classification of the genus Haliotis. Our results will provide valuable data for biodiversity conservation and management of abalone population in Korea.

As Backje(B.C. 18-A.D. 600) is the whole area of Chungcheong, Jeonra, Kangwon and Gyeongsang provinces, the son of the founder of Goguryeo, King Onjoe, making the castle Wu'irae capital of the nation, founded Backje. The capital was transferred to Hansung by B.C. 5 and then to Gongju by A.D. 475. Backje governed the east of China and the northeastern coast. Due to the effect of Chinese culture there are remarkably Chinese cultural elements in dress and its ornament of Baekje. Therefore on the side of cultural part, the noble culture was formed more polished than that of Goguryeo, which affected the culture of dress and ornament. And also there were class differentiation noticeably. Baekje created splendid culture and affected the culture development of Shinra and Japan. The motive of culture creation could be the top of three countries in the foreign trade because there were geographically the widest vast plain and coastline which stretches out from north to south. Although there haven't been many materials about the cultural heritage and records more than other countries, through the modern visual point its design is fresh and more elegant those of other countries. But the fact is that there are few materials related to Baekje. What is worse, there rarely remains all original form and most of them are broken and lost. According1y, we cannot understand not only an original form of Baekje culture and but also the meaning included in it. It goes without saying that there are few materials about the clothes and fabrics. As understanding the culture of Baekje itself is insufficient, a culture enterprise utilizing it - to improve both the added value and economical achievement while combining the latest culture resources with other fields - hasn't been successful. In this study, the purpose is to improve economic power through commercialization and industrialization of the sources of the culture of Baekje. By reanalyzing a form and an image of Baekje relics, it is designed with new motif and modem preference on the condition of our peculiar cultural heritage. And while using this motif with Jacquard pattern, we made it possible to be applied to real life such as interior trinkets, etc.
