  • This is the first report of Brachirus annularis (Pleuronectiformes: Soleidae) from Korea. A specimen of B. annularis (229.0 mm standard length) was firstly collected by drift gill net at a fishing ground locating between Jejudo and Geomundo Islands, the southern coast of Korea on 31 March, 2019. This species was characterized by having five large, deep colored patches on the ocular side of body, each patch outlined by dark brown ring, united dorsal and anal fins jointed with caudal fin, and short pectoral fin. We add this species to the Korean fish fauna and propose its new Korean names, "Eol-luk-seo-dae-sok" and "Eol-luk-seo-dae" for the genus and species, respectively.

  • TFT-LCD의 생산 과정에서 나오는 불량 제품의 검출은 자동화 과정에 의해 선택된 잠재적 불량 제품의 선택에 이은 인간의 목시검사에 의한 판단을 통해 이루어진다. 이러한 목시검사를 자동화하기 위해서는 불량의 식별성에 영향을 미치는 각 요소들에 대한 정량적인 분석, 그리고 각 요소들과 실제 최종적인 불량 판단 여부 사이의 체계적인 함수 관계의 파악이 필요하다. 본 논문에서는 TFT-LCD의 영역형 얼룩을 구성하는 특징적인 요소들을 정의하고, 이를 통해 불량 수준을 정의하는 수치화 함수를 유도하는 과정과, 이를 영역형 얼룩의 불량 수준 수치화에 적용한 결과를 보여 준다.

  • Two species of the genus Koreocobitis in Korea are reviewed with a key to species and their illustrations: Koreocobitis rotundicaudata and K. naktongensis sp. nov. A new species, Koreocobitis naktongensis is described based on 9 specimens collected from the Naktong River, Korea. The new species is distinguished from Koreocobitis rotundicaudata by the following combination of characters: yellow body colouration with many brownish speckles, truncate caudal fin, fewer vertebrae, and longer head. It is remarked biogeographically that Koreocobitis naktongensis is distributed only in the Naktong River, Korea.

  • In order to determine population dynamics of Anopheles sinensis, a survey based on average number of female mosquitoes per trap-night was carried out during the period of 5 years from 1987 to 1991, A. sinensis Birst appeared between the 2nd and 20th April, and were trapped in large number between the 5th and 12th July. The number of trapped mosquitoes began to decrease from mid-August, and a few were collected until mid-November, each year. The average number of A. sinensis in July was 542.6 per trap-night in 1987, but in 1989 increased abruptly to 1,331.4, and then decreased to considerably lower levels, 271, 9 in 1990 and 372. 1 in 1991. The nocturnal activity of A. sinensis to attack humans was found to become active in the early night, and it was gradually decreasing at mid·night, however, then slightly increasing toward dawn. The immature stage of A. sinensis in the rice paddies was Birst found in the correlation pattern with peak adult densities in early July. The highest larval density of A. sinensis in the study area was 21,226×103 in early July 1990. The larval A. sinensis showed high resistance level and resistance ratios against 3 kinds of organo- phosphorous compounds, diazinon, malathion, and fenitrothion, but low resistance against fenthion. The present results indicated that the population density of A, sinensis in Kyongbuk area is decreasing over the five·year from 1987 to 1991. Key words: Anopheles sinensis, seasonal prevalence, population dynamics, Kyongbuk Province.

  • This study was conducted to elucidate the seasonal prevalence of adult mosquitoes and occurrence of anopheline larvae in Gimpo, Gyeonggi province, Republic of Korea. Sampling of adult mosquitoes was carried out 18 times from May to September in 2008, using light traps at six sites. A total of 48,919 individuals belonging to 16 species and 8 genera were collected. Aedes vexans nipponii (43%) was the most frequently collected, followed by Anopheles sinensis (34%) and Culex tritaeniorhynchus (14%). The seasonal prevalence of anopheline mosquitoes had a different occurrence compared to that of Cx. tritaeniorhynchus. Anopheline larvae were collected using a standard dipper (size = of 350 ml) at eight habitat types of 203 point locations. Anopheline larvae were confirmed from 138 points (63%). The average larval population per dipper was highest in the lotus plantation (6.9 individuals), followed by irrigation channel (4.5 ind.), dropwort field (3.4 ind.), fallow field (3.1 ind.), paddy field (1.8 ind.), swamp (1.4 ind.), and stream (0.2 ind.). There was no significant relationship observed between larval density and DO, pH, salinity, or distance from blood meal hosts (cowshed, pigsty, chicken-house). In the results of average nearest neighbor analysis (ANNA), the distribution of whole points for mosquito larval collection was clustered, and points with over 4.0 larvae per dipper were randomly distributed. Within the study area Haseong-myeon, those points where over 3.0 larvae were collected were of a dispersed distribution.

  • 대한민국 국민들이 가장 좋아하는 식품은 아마도 쇠고기일 것입니다. 하지만 수입쇠고기는 불안하고, 한우는 가격 때문에 부담스러울 것입니다. 그래서 한우보다 경제적이면서, 수입산 보다 믿을 수 있는 맛있는 쇠고기 '육우'를 소개하고자 합니다. '육우'란 국내법상 한우고기와 젖소고기를 제외한 모든 쇠고기를 의미하지만, 대부분은 고기생산을 주목적으로 사육된 얼룩소 수소를 말합니다. 얼룩소(홀스타인종)가 수송아지를 낳으면 한우와 같이 전문적인 사육방법으로 비육시켜 전문고기소 '육우'가되고, 암송아지를 낳으면 우유를 생산하는 '젖소'가 됩니다.
