Soundscapes have the potential to help people experience the historical background and cultural traditions by the scenery of a local area and to be used as a cultural and tourism resource. This concept was first explained in detail by M. Schafer and has been developed as a new way of experiencing landscapes using various senses. This research studied the soundscape of Kyodong Island, the so-called "Island of Peace" and designed new cultural acoustic content for education and tourism. Kyodong Island is located right below the Northern Limit Line and the whole island is in the Civilian Controlled Area. The political and economic status of the island has been changed dynamically by the Korean War and the division of the country. These days, the island needs to realize the vision of the "Island of Peace" in a more creative way using local resources, including its "cold war landscape" and the natural scenery of the region. This research applied the concept of a soundscape to document the island, and to reproduce it in an artistic way. A workshop was conducted to learn concepts and techniques of soundscapes with a sound artist. Listening, recording, conducting interviews, and literature research was used to study the soundscape of the island. After that, this research reconstructed the soundscape of the island through a soundscape composition. The main theme of the composition story was the "Hope and Wish for the Harmony and Peace" to show the vision of the "Island of Peace". The initial sub-theme for the introduction part was "First Encounter with Kyodong Island" arranging the representative soundscape, which could be the first impression of the region. The second sub-theme was "War and Tension" using several soundscapes as a metaphor for the tragedy of the Korean War. The third sub-theme was "Everyday Life of Kyodong Island" which described the energy of the present day, after the wounds of the war have healed. The final sub-theme was "Harmony and Peace" using traditional music and keynote sounds of the region as a reminder of the peaceful past, before the war. The recording files were documented as two types of sound maps. One was a two-dimensional map to show the soundscapes from one point of view, and the other used the online application called "Sound Around You". The final artwork was displayed at an exhibition and uploaded on YouTube to be shared publicly. Through this project, we discovered the potential of soundscapes as a medium to preserve the history and local identity, as well as presenting a new vision. The artwork will be exhibited at historically and culturally meaningful places on the Island to utilize the underused places as local tourist attractions and educational resources.

This study was conducted to investigate marine algal community characteristics and the status of barren ground in the summer at study sites on Jeju Island, Korea. Sampling was carried out from July to September 2017 using a qualitative and quantitative survey (including coverage of non-geniculated coralline algae and density of grazer) by scuba diving. A total of 121 species were identified, including 11 (9.1 %) green algae, 24 (19.8 %) brown algae, and 86 (71.1 %) red algae. Hyeongjeseom had the greatest diversity, with 60 species, and Harye the least, with 18 species. The mean biomass at the study sites was $1,503.0g{\cdot}m^{-2}$, while the mean for the neighboring islets ($3,268.7g{\cdot}m^{-2}$) was higher than that of the main island ($914.7g{\cdot}m^{-2}$). Also, dominant species was identified: Sargassum macrocarpum at the neighboring islets, and Ecklonia cava at the main island, with differences showing not only in biomass but also species composition. In conclusion, the marine algal community status in summer at the study sites was evaluated based on the algal community characteristics (species composition, biomass, biomass ratio of kelp species), coverage of non-geniculated coralline algae, and density of grazer. As a result, both Hyeongjeseom and Marado require preservation and management to maintain their excellent marine algal communities, and other sites on the main island require the creation and/or restoration of marine algal communities. In addition, as the generation of barren ground accelerates, it is urgent not only to grasp existing monitoring research but also to identify the status of the marine algal community where it is not known at present.

The extensive hydrothermal deposits have been found, for the first time, on the western TA25 seamount caldera in the Tonga arc. The seafloor hydrothermal vents are active and immature, emitting the transparent fluids of which temperatures range from $150^{\circ}C$ to $242^{\circ}C$ (average=$203^{\circ}C$). The recovered hydrothermal sulfides are mainly composed of sphalerite, pyrite, marcasite, galena, chalcopyrite, covellite, tennantite, enargite and sulfates such as barite, gypsum/anhydrite. Predominant sphalerite categorize it into Zn-rich hydrothermal ore body. Zn-rich sulfide ores have minor enargite, indicating that mineralization occurred in high sulfidation environment. The proportion and FeS content of sphalerite increase from outside to inside of the hydrothermal ores, respectively. In particular, sphalerite has a great silver content (up to ~10 wt.%). Chalcopyrite is more frequently observed in mound than in the chimney, implying mineralization temperature in the mound is higher than in the chimney. Homogenization temperatures and salinities from fluid inclusions in barite at the mound range from $148^{\circ}C$ to $341^{\circ}C$ (average=$213^{\circ}C$) and 0.4 to 3.6 equiv. wt.% NaCl, respectively. Homogenization temperatures suggest that sulfides in the mound mineralized at a higher temperature (${\geq}200^{\circ}C$) than in the chimney.

The amplitudes of the M2 tide recorded at Seoguipo and Jeju are 77.9cm and 70.1cm respectively, which differ by 7.8cm over a distance of 30km across the Jeju-Do. The difference is an example of the geographical variation of the tidal amplitude around the Jeju-Do, the larger amplitude being along its southern coast compared with that along its northern coast. This variation can be explained in terms of effects of an island on the wave propagation as modelled by Proudman(1914). A numerical experiment of the M2 tide around the Jeju-Do reproduces the basic pattern of the observed variation and results are consistent with the theory. Due to the rotation of the earth larger and smaller amplitudes result along the left-hand and right-hand coasts of an island for an observer facing the direction of the wave propagation in the northern hemisphere.

By the continued island-mainland bridging works, increased consumer demand for seashore regions and fundamental improvement of accessibility to metropolitan areas, rural service industries in the island areas has been rapidly developed in the past decades, and also, their functions differentiated geographically. In most island areas, catering and accommodation sectors have been expanded, while traditional trading sector decreasing. And the dominant power of public sectors has been increased but private ones decreased. So, the overall development trends of service industries in island areas would be considered as unhealthy for rural economic sustainability. As a tentative solution, it may be proposed that through the functional specialization/differentiation and efficient linking/networking of rural service industries with multifunctionality of countryside capitals, their spatial cohesion would be strengthened.

To elucidate the distribution of halophytes in Korea, we surveyed 95 coastal salt marsh and sand dune areas. As a result, 62 halophytes of 57 species, 4 varieties and 1 form belonging to 44 genera and 21 families were recorded from coastal regions and islands of South Korea. Of these, 33 taxa were plants growing on sand dunes and the other 29 in salt marsh. Fifty eight taxa were found on the west coast, which was surveyed at 61 areas. The most common species among them were Suaeda glauca (Bunge) Bunge, Suaeda japonica Makino, Phragmites communis Trin., Zoysia sinica Hance, Carex scabrifolia Steud. in salt marsh, and Salsola komarrovii Iljin, Lathyrus japonicus Willd., Limonium tetragonum (Thunb.) A.A. Bulloc, Calystegia soldanella Roem. & Schult. on sand dunes. On the other hand, only 45 taxa were found on the southern coast, surveyed at 15 areas. On the east coast, surveyed at 13 areas, 44 taxa were found. The most common species were Salsola komarrovii Iljin, Lathyrus japonicus Willd., Calystegia soldanella Roem. & Schult., on sand dunes and Linaria japonica Miq., which on the Korean peninsula is found only on the east coast. On Jeju Island, surveyed at 6 areas, 30 taxa of halophytes were found. Canavalia lineata (Thunb.) DC. is found in Korea only on Jeju Island. About half of the Korean halophytes were members of three families (Chenopodiaceae: 12 species, Poaceae: 12 species and Asteraceae: 7 species).
