  • This study analyzed characteristics and tendencies of seasonal change on shoreline and beach with 8 beaches at East Sea coast by topographical survey for 2 years from March 2012 to February 2013. The shorelines of East Sea coast appeared that amount of seasonal change was bigger than amount of annual change. The seasonal change tendencies between Gangwon-do and Gyeongsangbuk-do coast areas existed some regional differences. To synthesize seasonal changes on 8 beaches of East Sea coast, shoreline advance and beach deposit showed clearly in summer and shoreline retreat and beach erosion showed clearly in autumn. This result is different from tendencies of seasonal change in many mid-latitude coast areas of the world, but generally corresponds with reference studies in west coast and east coast. The major factor of beach erosion showing mostly in summer is storm wave caused by typhoon. The beach erosion by storm wave also occurred in late winter. And it assumes that the beach deposit showing mostly in autumn is result of equilibrium processes of coast area against strong erosion in summer.

  • This study tries to examine papers on coastal terrace in the East Coast of South Korea and to summarize formative age and elevation of the terrace. Spatial and temporal variations of uplift rate in the Coast based on absolute age published are also reviewed. The terrace in the middle part in the Coast from Goseong to Samcheok distributes in an elevation of 10-20 m and its formative age is MIS 5a. The terraces during MIS 5e and 7 develop on an elevation of 20-35 m and 60-80 m, respectively. The mid-southern part in the Coast from Uljin to Yeongil Bay has the terraces with elevations of 10-25 m and 25-45 m and their ages are MIS 5a or 5c and 5e, respectively. The terraces with elevations of 10-25 m and 30-45 m correspond to MIS 5a and 5e, respectively, in the southern part in the Coast from Homigot to Busan. Assuming that elevation of sea level during the formation of each terrace is the same as in the present time, uplift rates in the Coast range from 0.05 to 1.36 m/ky with an average of approximately 0.33 m/ky. The highest and lowest rates since MIS 5 are found in the Gyeongju (approximately 0.39 m/ky) and Pohang (approximately 0.19 m/ky) areas. With a consideration of elevation of sea level at that time, however, the middle, midsouthern and southern parts in the Coast show uplift rates of 0.16-0.28 m/ky, 0.20-0.36 m/ky and 0.24- 0.36 m/ky since MIS 5, respectively, suggesting that the southern part in the Coast has experienced relatively higher uplift rate.

  • The east coast seems to have remarkably different features from the west and south coast in the geographical, geomorphological, and oceanographical senses. In this paper the auther wishes to introduce some results of investigation morphological characteristics of the river mouth in the east coast an of analysis of it's causes. There are various closing form in river mouth by many causes, but the east coast hs the same closing form(the ratio of closing; roughly 0.18), as well known, by the sand spit, and has not hydrological but littoral drift background. The river of the east coast is proved mature age from hypsometric analysis. The wave and longshore current must be principal factor to be considered, in the analysis of the closing phenomenon owing to littoral drift. The research of the blown sand is considered valuable for the next study of this subject.

  • By Chinese growth, economic development and investment of the West-coast are consisting. Specially, the West-coast area need tourist development and tourism Import for the Incheon and the Pyeongtaekhang of the Gyeonggido Province, China trade through the Chungcheongdo Province area. According to such regional special quality, the railroad tourism industry should be activated. Sunset of tourism infra in the West-coast is high value as representative goods of the West coast. Development of the theme railroad tourism industry that utilize the tide may maximize regional advantage of China and capital region. This research is basis investigation to examine development possibility as sunset theme railroad tourism industry of the West-coast. Scope of this research limited by the sunset theme railroad tourism industry for the Chungchongdo Province area.

  • It is necessary to prepare a plan to accommodate the International Convention in domestic law, focusing on the new duties for the Coast Guard as they pertain to the field of ship recycling, by studying the key issue of the "HONG KONG International Convention for the Safe and Environmentally Sound Recycling of Ships" of the International Maritime Organization(IMO) and through analyzing the current status of the Coast Guard. The Coast Guard is directly responsible for the protection of the marine environment and takes charge of important duties; Therefore, by instituting a legal basis for its new duties, it will not only create new business but also be able to consolidate its role as an important constituent in the sphere of marine conservation and protection.

  • Tarballs formed by HEBEI SPIRIT oil spill observed in the south-western sea of Korea from December 27 2007. The tarballs were removed by the response party, which Korea Coast Guard became a center of organization. The amounts of removing tarballs form the sea and the coast were 0.345 tons and 1,739 tons, respectively. The number of persons, in order to remove the tar balls from the south-western sea of Korea, counted about 97,000 persons, including 25,000 volunteers. In this paper, we introduced the response methods of tarballs entering into the south-western sea of Korea such as a landing net, meshes and so on.

  • On the analysis of the regional organizations of coast guards in USA, Japan and BK, the ideal organization of area coast guard of Korea is proposed. It is composed of three area coast guards in West, South and East sea and special units in order to carry out missions and to response requirements and needs in the maritime fields in object oriented way. The proposed regional organization can be actualized as the model of development by improving the listed tasks.

  • The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon. tidal wave. flood and storm. Especially. 409 cases. which reach to about $40.9\%$ of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than $40\%$ of natural disasters also occurred every year is happening in coastland. Therefore, there is a great need to construct all related GIS database such as atmospheric phenomena (typhoon. tidal wave, flood and storm). harbor facility, harbor traffic and ebb and flow. Furthermore. the certain system should be developed and integrated with NDMS (National Disaster Management System) by using 3D web GIS technology. In this study. the coast disaster area management system was designed and developed by using 3D web GIS technique so that the coast disaster area could be monitored and managed in real time and in visual. Finally. the future disaster in coast area could be predicted scientifically.

  • The study was carried out to determine the changes of growth characteristics, anthocyanidin, and brown rice yield grown at coast and inland areas apart from the east coastline of Gyeongsangbuk-do province. Number of spikelets per panicle was much more increased in inland area. Regional difference in number of spikelets per panicle was observed in Jeongjinju cultivar. Among these red rice cultivars, the highest brown rice yield was Jeongjinju rice cultivar having 702 kg in inland area and 692 ㎏ in coast area, respectively. Anthocyanidin content ranged 524 to $610{\mu}g/g$ dry weight basis. Cyanidin content was 11.4 to 14.0 times higher than that of delphinidin under coast and inland area. Anthocyanidin content was higher in rice cultivar grown at coast area. Highest head brown rice rate was only observed in Geonganghongmi to 95.2 at coast area and 95.4 inland area. In considering brown rice yield and pigment content, Hongjinju rice cultivar was recommended in optimal pigment rice cultivar in eastern coast of Gyeongsangbuk-do Province.
