  • As a result of continuous taxonomic investigations of Korean crabs, Pugettia intermedia Sakai, 1938 is newly reported from Korean waters. Pugettia intermedia had previously been reported in Korean fauna, but the previous reports of P. intermedia were resulted in misidentification of P. quadridens (De Haan, 1839). Pugettia intermedia differs from P. quadridens in having two subequal medial lobes of the first pleopod in male. In P. quadridens, one of the two medial lobes is about half-length of the other. Pugettia intermedia occurs on the southern coast of the Korean peninsula. The descriptions and illustrations of this species are provided herein.

  • In order to determined the appropriate processing season of Pacific oyster (Crassostrea gigas), 30 individuals cultured in Kamak Bay on the southern coast of Korea were taken bimonthly 7 times a year, and seasonal variation of edible portion weight, edible portion yield and coefficient of fatness were investigated. There were close relationships between edible portion weight (X) and total weight (Y) and between coefficient of fatness (X) and edible portion yield (Y), which were expressed in regression lines, i.e. Y=0.2709X-1.9094 (r=0.9254) and Y=44.0596X+ 15.1127 (r=0.8485), respectively. From the results of seasonal variation of edible portion weight, yield and coefficient of fatness, the appropriate processing season of raw Pacific oyster was between winter and spring, that is, between December and following April the next year.

  • 2004년 8월 제주도 남부연안에서 집어등에 의한 연안 자치어 조사과정 중에 당멸치과 (당멸치목)에 속하는 엽상자어 3개체 (표준체장 33.4~35.2 mm)를 채집하였다. 이들 엽상자어는 꼬리지느러미가 이차하고, 뒷지느러미가 작으며, 그 기점이 등지느러미 후단부 하방에 위치하는 점에서 '당멸치 Elops hawaiensis'로 동정되었다.

  • All the submarine cable lines have been repaired restored and newly installed since 1970' s they were installed by the foreign technician around the islands off the southern and western coast of Korean peninsula. But April, 10th, 1998, for the first time in Korea, we Korean team of technicains succeeded in repairing and restoring the troubled cable lines from HEUGIL island to MASAG island, WANDO county, CHUN-NAM province. This job was done only by applying our newly researched and developed technology. The troubled cable lines were connected again by this technology.

  • In this study, a two-dimensional storm surges/tide prediction model called the Storm surges/Tide Operational Model (STORM) was applied as the operational forecast model of the Korea Meteorological Administration (KMA). The operational model results were verified for two years (2006-2007) using observed results from tidal stations. Comparisons of modeled and observed storm surges show that larger differences at the western coast of Korea than at the southern and eastern coasts. The averaged root mean square error between the modeled and observed storm surges height are 0.16 m and 0.10 m in 2006 and 2007, respectively.

  • A new species, Dimorphostylis namhaedoensis (Cumacea, Diastylidae) is described on the basis of the specimens collected from southern shallow coast of Korean peninsula. The new species resembles four other species, D. asiatica, D. valida, D. hisuta and D. acroplicata, in having three apical spines on the terminal margin of the male telson and three pairs of the oblique ridges on the carapace, but are obviously distinguished from them in that the pattern of the ridges on the carapace is different and the third article of the antennular peduncle is very long in female. Furthermore, the dorsal carina of the female carapace has a row of forward spines and among the three apical spines of male telson, the median spine is much smaller than the lateral ones.

  • A mysid species, Parastilomysis paradoxa Ii, 1936 belonging to the subfamily Mysinae Hansen, 1910 which comprises approximately 90% of all mysid species, is newly reported from Korean waters. The genus Parastilomysis Ii, 1936 which is also new to Korea, is distinctly different from other genera by having biramous third and fourth pleopods of the male, and telson with an apical cleft. In the present paper, authors provide detailed descriptions and illustrations of P. paradoxa based on the specimens collected from the southern coast of the Korean peninsula, and also discuss on the zoogeographical distribution herein. Parastilomysis paradoxa belongs to Mysidae Haworth, 1825, and is the 50th species in Korea.

  • Recently construction of new transmission line is getting harder because of social hostility to transmission tower. Howevere, load is converged in metropolitan area and power plants near this area are old and life of generator will end soon. Therefore, power to supply load in this area should be transmitted from east coast area and southern area. For these reasons, securement of transmission capacity without new transmission line construction is important. In this paper, effect of one circuit AC line change to DC transmission at the same transmission tower on the system available transfer capacity is analyzed.
