AThis paper measured real sea area for performance analysis according to distance from west sea and south sea of Korea. The performance of the underwater OFDM system was analyzed by comparing the performance of the West and South Seas by adjusting the number of data repetitive transmissions and the pilot symbol placement interval parameters based on the real-sea data measured from the distance and Data rate of the West and South Sea vessels. In conclusion, when comparing the performance of the South Sea at the Data rate and distance, the BER performance of the South Sea was similar at the 5 km South Sea and 1 km West Sea under the same conditions. Placement interval of pilot symbol at 10 km of South Sea and 3 km of West Sea is (𝚫f, 𝚫t) = (6, 3) and the number of times the PRB is (R_f, R_t) = (2, 1) repeated. We confirmed that we can send high data over long distances in the South Sea.

Twently seven speices of marine bryozoans from Namhaedo Island and its adjacent waters were identified. Among them, Hippothoa distans is new to Korean fauna and seven species are added as new to Namhaedo Island fauna. Twenty three species of them have been found also in Chejudo Island waters, which is affected by the Tsushima Current. Ten species have been found in the East Sea which is affected by both the Tsushima Warm Current and the North Korea Cold Current. So it is clear that the Namhaedo Island sea area is influenced by both the Tsushima Warm Current and the North Korea Cold Current.

Quantitative real-time polymerase chain reaction (qPCR) was applied for the early detection of red tides in the coastal areas of South Gyeongsang in 2019. Cochlodinium polykrikoides (Dinophyceae) was detected at very low cell densities (0.0015~0.0058 cells mL^-1) in early June, but its cell density increased by up to 0.163 cells mL^-1 in mid-August. Higher cell densities were detected mainly in Namhaedo using both qPCR and microscopy (maximum 24 cells mL^-1) in late-August. Accordingly, a red tide alert was issued on September 2 (maximum 200 cells mL^-1) on this island. C. polykrikoides cell density in Namhaedo peaked on September 11 (12,000 cells mL^-1). Our results indicate that C. polykrikoides was detected at very low cell density in Namhaedo prior to bloom, which occurred in the same area. Therefore, qPCR is a useful tool to detect even at very low cell densities of C. polykrikoides for early warning of blooms.

In this study, fish fauna and stream characteristics were surveyed from June to October of 2014 in 31 sites of 23 small streams of Namhae Island. During the study period, 38 species belonging to 30 genera under 13 families were collected. Cyprinidae and Gobiidae fish occupied 28.9% (11 species) and Cobitidae fish accounted for 10.5% (4 species). The dominant family was Cyprinidae, and the most dominant species was Zacco koreanus with 30.3% (1,089 individuals) of the total. Eight species (33.8%) such as Zacco koreanus, Squalidus gracilis majimae, Coreoleuciscus splendidus, Pseudobagrus koreanus, Iksookimia hugowolfeld, Iksookimia longicorpa, Silurus microdorsalis and Liobagrus mediadiposalis were Korean endemic and one species of Micropterus salmoides was exotic. According to the analysis of the community based on the diversity, evenness and richness indices, fish community seems to be more stable in the S7. The small streams were classified into three types of steep mountainous, mountainous-flatland, and flat land streams, and their types were categorized by their features of stream width, water depth, bottom substrate, riparian vegetation, and land use patterns. Principal component analysis based on species abundance classified fish communities into three main groups according to human impact and land-use pattern change. These results suggest that fish community structures were primary affected by the longitudinal environmental changes and these were modified by the habitat condition in accordance with the land use pattern change in the small streams.

광양만 및 주변해역의 참굴을 대상으로 환경생체지표를 측정하여 환경독성을 조사하였다. 광양만에서는 세포치사독성은 나타나지 않았으며, 라이소솜의 안정성은 남해도 주변정점은 70%내외 인데 반해서, 기준정점의 50% 내외의 상대적으로 낮은 안정성을 보인다. 에스테라제 활성은 광양내만 및 태인교 부근의 정점과 남해도의 정점 8, 9 들은 63-88 FU 정도로 낮아서 활성이 저해 받고 있음을 알 수 있다. 이중나선 DNA의 함량은 남해도의 정점들은 150 FU 내외의 값을 보이고, 광양만은 130FU 내외로 함량이 낮고, 정점간의 차이가 크지 않다. 전체적으로 기준정점 및 외양역의 정점 10은 독성물질에 의한 영향이 적은 데 반해서, 광양만은 독성물질에 의해서 특히 라이소솜 온전성, 에스테라제 활성 등에 영향을 받고 있는 것으로 사료된다. 그리고 남해도 주변의 인근해역은 광양만에 비해서는 적은 영향을 받고있는 것으로 사료된다. 다른 측정자료와 비교하여 볼 때 광양만지역은 거제도와 같은 청정해역보다는 독성물질의 영향을 더 받았고, 마산과 같은 극심하게 오염된 지역보다는 독성물질의 영향을 적게 받았다. 인접한 가막만과 유사하거나 조금 더 독성물질의 오염에 의한 영향을 나타내는 것으로 사료된다. 퇴적물 독성실험에서 200 mg/ml(이하 mg)이상의 농도에서 전정점에서 100 mg에서 부분적 및 세포치사독성이 나타났으며, 라이소솜 안정성은 50 mg에 노출 했을 때에는 정점, 12, 20, 26, 42 에서는 25% 내외의 낮은 값을 보이고, 대부분의 정점에서 50 % - 70% 내외의 온전성을 보인다. 에스테라제 활성은 100 mg에 노출했을 때 묘도와 광양제철 인근에 위치한 정점 10, 12, 16, 22에서는 50 %내외의 값을 보였고(정점 22: 36%로 최저), 내만에 위치한 정점들에서는 60% 내외의 활성을 보였다. 양식장이 있는 정점 2, 외양의 영향을 많이 받는 정점 46, 51, 54 등은 활성 값이 70% 이상으로 퇴적물 독성이 상대적으로 낮았다. 이중나선 DNA 함량은 28.4 % - 49%로 대조군에 비해서 감소가 크다. 대부분의 정점이 대조군의 30% 내외로 정점 간의 차이는 크지는 않다. 그러나 다른 측정자료와 같이 정점 22에서 18%로 최소치를 나타내고, 정점 2, 12에서 20% 내외의 값을 보인다. 종합적으로 볼 때 오염물질의 유입이 크고, 광양제철 인근 정점 들이 모두 다른 정점에 비해서 낮아서, 퇴적물 독성이 높은 정점으로 조사되었다.

Saussurea namhaedoana, a new endemic species narrowly restricted to Namhaedo Island of Korea, is reported in this study. It can be distinguished from other congeneric species of Saussurea in Korea by having persistent radical leaves until flowering, hastate or sagittate leaves with mucronate toothed to undulate-lobulate margins, grayish cobwebby hairs on abaxial leaf surfaces when young, and tubular involucre with grayish cobwebby hairs. Morphologically, S. namhaedoana is closely related to other species in Korea, such as S. gracilis Maxim., S. insularis Kitam., S. seoulensis Nakai and S. albifolia M. J. Nam and H. T. Im, sharing grayish or white hairs on the abaxial leaf surfaces. It, however, can be distinguished from its close relatives by having a distinct leaf shape, i.e., sagittate or hastate leaves. The phylogenetic relationship relative to congeners in East Asia is yet to be determined.

본 연구에서는 남해 주변해역의 조석과 조류의 구조특성을 해석하기 위해 현장관측결과와 수치실험결과를 이용하였다. 남해 주변해역의 해수유동은 2003년~2008년 사이 노량수로, 대방수로, 여수수로, 창선수로, 강진만, 앵강만에서 ADCP 및 RCM 9 유속계를 사용하여 각 정점에서 1개월 정도 연속측류를 하였다. 노량수로와 대방수로에서는 ADCP를 사용하여 표층에서 저층까지 3m 간격으로 측류하였고, 여수수로, 창선수로, 강진만과 앵강만에서는 RCM-9 유속계를 사용하여 표층에서 연속 측류하였다. 노량수로 상층에서 동-서 방향의 최대 유속은 약 165~175 cm/sec, 대방수로에서는 창 낙조류 최대유속은 약 200~270 cm/sec, 여수수로에서는 약 85~96 cm/sec 정도 나타났다. 강진만의 표층에서 최대유속의 크기는 창 낙조류 비슷하게 35~46 cm/sec, 앵강만 입구 부근에서 낙 창조류 최대유속은 20~22 cm/sec으로 발생하였다. 또한, 조류수치모형실험을 수행하여 남해 주변해역의 조류분포 특성을 전반적으로 해석하였다.

In-situ observational works had been done for the investigation of Cochlodinium polykrikoides cell distributions and abundances off the coast of Busan, Jinhae Bay, and Namhae to Tongyong area in the early June, 2004. The surface water of 11 was concentrated by passing through ${\Phi}$ 10 $\mu\textrm{m}$ mesh and cellular morphological characteristics of the species in the sample was observed under light microscope equipped with digital camera on the vessel. C. polykrikoides cells showed highest cell numbers ranging from 60 to 660 cells/1 at Jinhae Bay. Cell counts at offshore area of Busan ranged from 45 to 330 cells/1. However, no cell was found in the water between Namhae and Tongyong. C. polykrikoides found during the cruise had a large bright red and round cellular materials in one cell and two-celled chain of C. polykrikoides. The red material decreased as C. polykrikoides formed long chains through cell divisions.
