Wegener`s granulomatosis is a necrotizing, granulomatous vasculitis that involves multiple organs including the upper and lower respiratory tract and the kidney. The kidney initially exhibits focal necrotizing glomerulonephritis, which progresses to crescentic glomerulonephritis in Wegener`s granulomatosis. We experienced a case of Wegener`s granulmatosis which was associated with a thin glomerular basement membrane disease. The patient suffered from nasal stuffiness, recurrent serous otitis media, and tinnitus. Despite antibiotic therapy and ventral tube insertion, symptoms did not improve and hearing difficulty was aggravated. Ulcerative, necrotizing granulomatous inflammations with multinucleated giant cells were seen on nasal biopsy. She had recurrent microscopic hematuria and the renal biopsy findings by light and immunofluorescent microscopy did not reveal any abnormalities but diffuse thinning of the glomerular basement membrane (226nm) was observed by electronmicroscopy. With the above clinical findings and biopsy results, we diagnosed Wegener`s granulmatosis with thin glomerular basement membrane disease. Thin glomerular basement membrane disease, also called benign recurrent hematuria, is characterized by diffuse thinning of the glomerular basement membrane and hematuria. Weekly low-dose methotrexate together with prednisone was used as treatment regimen because nonglomerular microscopic hematuria may be the first sign of cyclophosphamide-induced renal toxicity. With the above combination therapy, she felt well-being sense and her hearing difficulty was also much improved. She has been treated as an outpatient with glucocorticoid.

Catches, CPUE, fishing season, disc width composition and fishing ground were studied to rebuild skate ray, Raja pulchra resource by the offshore longline fishery in Heuksan-do, Korea. Annual catches and CPUE of skate ray were increased from 2003 to 2010 (CPUE: from 2007 to 2010) continuously. The main fishing season of the skate ray was from December to next May. Disc width at 50% maturity for Raja pulchra by sex were estimated to be 65.83cm, 57.01cm by female and male respectively. The range of disc width was 22.3-112.0cm and the average disc width was 66.9cm, 60.0cm by female and male of Raja pulchra respectively during 2007-2010. Annual average of disc width of female skate ray was decreased from 2007 to 2010. The fishing grounds were formed from the coastal water off Hong-do to the coastal water off Gyeogyeolbiyeol-do, Korea. The center of fishing ground in October was formed in the northwestern coastal water off Gyeogyeolbiyeol-do and separated from that of the other months.

한강 하구의 강화 갯벌 조간대에서 유영생물의 종조성을 파악하기 위히여 2009년 4월부터 12월까지 매월 1회 강화 석모수로 조간대에 설치된 건간망에 어획된 유영생물을 수집 분석하였다. 채집된 유영생물은 총 57종으로 그 중 어류가 34종으로 가장 많았고, 갑각류 20종, 두족류 2종 그리고 1종의 해파리가 출현하였다. 종조성은 봄과 가을에 다양한 종들이 출현하였으며, 양적으로는 가을에 많았다. 총 어획물중 꽃게 (Portunus trituberculatus)가 전체 개체수의 57.2%를 차지하여 가장 많았고, 다음으로 그라비새우(Palaemon gravieri) 7.1 %, 황강달이 (Collichthys lucidus) 7.0%, 무늬발게(Hemigrapsus sanguineus) 6.2%, 밀새우(Exopalaemon carinicauda) 4.7% 순으로 우점하였다. 우점종 중 가숭어(Chelon haematocheilus), 풀망둑(Synechogobius hasta), 웅어 (Coilia nasus), 그라비새우, 밀새우 등은 기수성 주거종이었으며, 꽃게, 황강달이, 숭어 (Mugil cephalus), 참서대(Cynoglossus joyneri) 등은 하구를 보육 및 성육장으로 이용하는 연안 회유종이었다. 그 외 양적으로는 적지만 황복(Takifugu obscurus), 참게(Eriocheir sinensis), 뱀장어 (Anguilla japonica) 등의 왕복 회유종과 붕어(Carassius auratus) 등의 담수종도 출현하였다. Seasonal variation in species composition of estuarine fauna in the Han River estuary was determined by analyzing monthly samples collected on the intertidal flat of Ganghwa Island by a fence net from April to December 2009. Total number of species was 57: 34 species of fishes, 20 species of crustacean, 2 species of cephalopods and 1 species of jellyfish. Of a total of 57 species, Portunus trituberculatus (57.2%), Palaemon gravieri (7.1%), Collichthys lucidus (7.0%), Hemigrapsus sanguineus (6.2%) and Exopalaemon carinicauda (4.7%) were predominated in abundance. Diverse species were occurred in spring and autumn, and abundance was high in autumn. Chelon haematocheilus, Synechogobius hasta, Co ilia nasus, P. gravieri and E. carinicauda were classified as the brackish residence species. P. trituberculatus, C. lucidus, Mugil cephalus and Cynoglossus joyneri were coastal migratory species which use the estuary as nursing and feeding grounds. Diadromous species (such as Takifogu obscurus, Anguilajaponica and Eriocheir sinensis) and freshwater fish (Carassius auratus) were also collected.

To understand the fishery characteristics by a beam trawl off the coast of the Chungnam province, covering $125^{\circ}$ 50'~$126^{\circ}$ 05'E, $36^{\circ}$ 15'~$36^{\circ}$ 25'N, a beam trawl was deployed 2~4 times a month from March 2008 to February 2009. The catch was consisted of 96 species of 63 families belonging to 19 orders. Among these, organisms were identified as 54 species of fish, 27 species of crustaceans, 9 species of gastropoda, bivalves, and 6 species of cephalopods. Trachysalambria curvirostris which is the target species of the beam trawl fishery occupied only 2.1% of the total catch, showing a low ratio of catches. Most of T. curvirostris was harvested from July to November while small amount of T. curvirostris was captured from May to December. In this study, we concluded that the bycatch ratio except T. curvirostris in T. curvirostris fishery was relatively high, thus the fishery of T. curvirostris might affect the fishery resource management of bycaught species off the coast of Chungnam province. 본 연구에서는 충남 연안에서 연안조망의 어획 특성을 파악하기 위하여, 2008년 3월부터 2009년 2월까지 매월 2~4회 연안조망을 사용하여 어획조사를 실시하였다. 조사 해역은 동경 125도 50분~126도 05분, 북위 36도 15분~36도 25분의 해역이었고, 총 19목 63과 96종이 채집되었다. 그 중 어류가 54종, 갑각류가 27종, 복족류 및 이매패류가 9종, 그리고 두족류가 6종이었다. 생체량은 어류가 51.4 %로 가장 많았으며, 갑각류는 34.2 %를 차지하였다. 꽃새우는 7월~11월에 출현량이 많았고, 12월부터 5월까지는 적은 양이 출현하였다. 연안조망의 목표종인 꽃새우는 전체 어획물의 2.1 %로 낮은 채집 비율로 출현하였으며, 꽃새우 이외 어종의 부수적 어획물의 양적 비율이 높아, 꽃새우 어획이 부수어획으로 어획되는 종들의 수산자원에 미치는 영향이 클 것으로 판단된다.

The age and growth of the Pacific cod, Gadus macrocephalus were investigated using left sagittal otoliths of 682 individuals collected in the West Sea of Korea from January to December 2007. The seasonal changes in the ratio of an opaque zone to interval between annular rings revealed that the narrow translucent parts of the otolith were annual growth rings formed between February and March once a year. The spawning period was December to January and therefore the duration from fertilization to the complete formation of the opaque zone became thirteen months. From the parameters calculated using the average length when the year ring was formed, the estimated von Bertalanffy growth equations were for females and for males when is total length in age t.
