This study analyzed distribution density in relation with sea-bed waste of the sea of north-eastern Jeju island by bottom trawl of 7 times for four days in April, June, October and November 2017. On the survey for four days many sea-bed wastes were collected at the sea of Jeju north-eastern fishing grounds. The kinds of collected sea-bed waste were the fish traps, the waste nets, the wire lines, the long lines, woods, plastics and so on. Distribution density in relation with sea-bed waste of the survey area was 109.8-596kg/km², and which proportion of the kinds on total sea-bed waste were that the fish trap was 66% (288 fish trap of 1011.6kg), the waste rope was 21%, the fishing line was 5.8%, the waste net was 1.9% and the others was 4.8%. According to the broken degree the serious broken fish trap were 101 (35%) and the intact fish trap were 187 (65%). As a result of survey of sea-bed waste in the Jeju north-eastern fishing grounds were polluted by the sea-bed waste and we need continuous monitoring to get rid of this environment pollution.

We investigated the characteristics of the marine environment and phytoplankton community of surface in the adjoining sea of Yangtze river of the East China Sea in June 2005. According to the analysis of a T-S diagram, three characteristic of water masses were identified. We classified them into the mixed water mass by the Chinese continental coastal waters and Taiwan/Tsushima warm current, Chinese continental coastal waters and Taiwan/Tsushima warm current. The first water mass was characterized by high water temperature, low salinity, low density and very high Chl-a concentration. The second one was characterized by high water temperature, low salinity, low density and high Chl-a concentration and the last one was characterized by low water temperature, high salinity, high density and low Chl-a concentration. The phytoplankton community identified a total of 95 species belonging to 43 genera. The dominant species was 3 species, that is, mainly centric diatom, Skeletonema costatum in the Chinese continental coastal waters. The others one, one dinoflagellates, Prororcentrum donghaiense and one silicoflagellates, Dictyocha speculum var. otonaria in warm current regions. Standing crops of phytoplankton and Chl-a concentration were very high with ranged from 5.9 x 103 cells/L to 1.1 x 106 cells/L, and 2.90 ㎍/L to 26.40 ㎍/L, respectively. Phytoplankton productivity in the East China Sea was controlled by the discharge of Yangtze river waters which include a high concentrations of nutrients.

This study analyzed ship traffic using in IBS (Integrated Bridge System) in relation to the volume of traffic at traffic separation zone marine traffic on route to or from Yeosu-Gwangyang Port and examined the risk factors and countermeasures for marine transport safety management. As a result of marine traffic survey in Yeous-Gwangyang port for three days in October 2017, daily average passing ships were 411 ships, and about 65% of the total passing ships between 06:00 and 18:00. The volume of traffic in the traffic separation zone as an incoming and outgoing vessel were about 370 of the total vessels and accounted for about 30%. The Dangerous cargo carriers accounted for 58% of all vessels, 27% of general cargo vessels, 9% of containership and 6% of other vessels. As a result of VHF, general reports were the most common items with 65%, information provision were 19%, response ship communication were 11%, non-response and warning measures were 5%. It was found that many cargo ships and tanker vessels in the traffic separation zone encountered the most frequently when incoming and outgoing routes. Consequently, the safety traffic separation schemes are as follows; A vessel using a traffic separation schemes needs the active passing management system in the traffic separation zone, where the medium work ships incoming and outgoing in the specified areas including the costal traffic routes is urgently needed safety management for the passing routes of large ships.

박예찬(Yeechan PARK),유진영(Jinyoung YOO),신형호(Hyeong-Ho SHIN),김영훈(Younghun KIM),김대진(Daejin KIM) 전남대학교 어업기술연구소 2021 어업기술연구소보고지 Vol.14 No.1

본 연구는 제주 서해 연근해 해역에서의 저서 어족생물의 조성, 체장, 중량을 파악하기 위하여 2018년 10월 22일부터 10월 24일까지 총 3회의 트롤 조사를 실시하였다. 조사해역에서의 어족자원에 대한 종조성은 1회 조사에서 우점종은 아귀, 꼼치, 갈치순으로 나타났고, 2회 조사에서 우점종은 딱새우, 아귀, 원숭이게, 성대 순으로 나타났으며 3회 조사에서 우점종은 아귀, 살오징어, 성대 순으로 나타났다. 총 3회 조사에서 어획된 개체 수 기준으로 총 어획량은 아귀가 제1의 우점종으로 나타났으며 다음으로 딱새우, 살오징어 순으로 나타났다. 또한 트롤 조사에서 어획된 어족생물에 대한 체장별 크기는 151∼200 mm 사이에서 최대 어획량을 나타내고, 어획된 중량은 다양한 어종이 다수 어획되어 중량 변화의 폭이 컸으며 거의 대부분 101∼200 g 사이의 저서어족이 어획되었는데 아귀의 경우, 체장이 작은 미성숙어 어류도 다수 어획되었다. 제주 근해 해역의 어장들은 적도에서 발원하여 태평양 서안을 따라 대만 동쪽으로 올라온 난류가 대마도를 거쳐 동해로 유입되는 대마 난류의 길목에 위치하여 각종 어류들의 회유와 산란 및 서식지로서 어업이 활발한 좋은 어장으로 알려져 있다. 그러나 제주 서해 연근해 해역 어장의 경우, 다른 제주도 연근해 해역의 어장들에 비해 어획량이 적은 것으로 나타났는데(Kim. 2017), 이러한 원인으로는 하층에서 상층으로 해수가 이동하는 용승작용이나 저질에 따른 플랑크톤의 차이 등 여러 요인이 있을 수 있다. 따라서 제주도 인근 해역 어장들의 어획량 차이에 대한 원인은 저서어족 생물의 자원 보호뿐만 아니라 다른 우점종의 어족자원에 대한 효율적인 보호와 관리를 위해 지속적인 연구 조사가 필요할 것으로 판단된다. The primary goal of this study is to survey a fisheries resources in west coastal sea area of Jeju island. The method of trawl survey conduct to fishing survey through cod-end of trawl and its cover net. The surveys are carried out 2 days on 22-24<SUP>th</SUP> Oct. in 2018 by the training ship “Sae Dong Baek” of Chonnam National University. The total fish species caught by trawl net during 3 times survey for 2 days were 28 species. In the first superior was Lophiomus setigerus, 378(66%) the next Metanephrops thomsoni, 74(12.9%) the third Todarodes pacificus 14(2.4%). In individual numbers the most fish body length size caught by trawl net was between 150 mm and 200 mm. In individual numbers the least fish body length size caught by trawl net was between 51 mm and 100 mm. The fish weight size caught by trawl net was for the most part, over between 101 g and 200 g. The fish weight size caught by trawl net was for the least part, over between 5,001 g and 15,000 g. Fisheries resource has been decreasing for years and years. For many years fisheries researcher have debated its management and regulation. Much yet studies are necessary about the fisheries resources and regulation. The more fisheries resources must be preserved continually.

Recently, three-dimensional (3D) light harvesting structures are highly attracted because of their high light harvesting capacity and charge collection efficiencies. In this study, we have fabricated Cu₂ZnSn(SxSe1-x)₄ based 3D thin film solar cells on PR patterned Molybdenum (Mo) substrates using photolithography technique. Specifically, Mo patterns were deposited on PR patterned Mo substrates by sputtering and the thin Cu-Zn-Sn stacked layer was deposited over this Mo patterns by sputtering technique. The stacked Zn-Sn-Cu precursor thin films were sulfo-selenized to form CZTSSe pattern. Finally, CZTSSe absorbers were coated with thin CdS layer using chemical bath deposition and ZnO window layer was deposited over CZTSSe/CdS using DC sputtering technique. Fabricated 3-D solar cells were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF) analysis, Field-emission scanning electron microscopy (FE-SEM) to study their structural, compositional and morphological properties, respectively. The 3% efficiency is achieved for this kind of solar cell. Further efforts will be carried out to improve the performance of solar cell through various optimizations.
