본 연구는 바지락 치패발생장 조성을 위한 모래살포가 저서동물군집에 미치는 영향을 파악하기 위해 수행되었으며, 모래살포 전 후 저서동물군집과 퇴적환경의 시.공간 변화에 초점을 맞춰 조사를 실시하였다. 모래살포 작업은 2010년 7월에 태안군 고남면 모래톱 갯벌에서 이루어졌으며, 현장조사는 모래살포구역(실험구)과 비살포구역(대조구)에 각각 3개 정점을 선정하고 2010년 6월부터 2011년 10월까지 총 10회에 걸쳐 진행하였다. 모래살포 후 실험구의 표층퇴적물은 극조립사로 변했으나 약 4개월 후부터 계절적인 세립화가 진행되어 약 8 개월 후 모래살포 이전과 동일한 극세립사로 되돌아갔다. 모래살포 직후 실험구 저서동물군집의 출현종수 및 개체밀도는 일시적으로 감소하였으며, 주로 Apocorophium acutum, Photis sp. 등의 갑각류에서 피해가 컸다. 그러나 감소된 출현종수와 개체밀도는 기존종의 회복과 주변 서식종의 재점유 과정을 통해 점차 증가하였으며, 출현종수는 모래살포 후 약 3개월 뒤에, 개체밀도는 약 4개월 뒤에 본래의 수준을 회복하였다. 저서동물군집의 우점종은 모래살포 전에 A. acutum, Photis sp. 등이었으나, 모래살포 직후 Heteromastus filiformis, Macrophthalmus japonicus 등을 거쳐, 가을 이후 Musculista senhousia, Ruditapes philippinarum, Mediomastus californiensis 등으로 변해갔다. 모래살포 후 일정시간이 경과하면서 표층퇴적물의 특성과 생태지수는 모래살포 전과 유사한 수준을 회복하였으나 군집의 구조는 지속적인 종조성 변화로 인해 연구 후반까지도 모래살포 전의 구조를 회복하지 못하였다. This study was conducted to investigate the impact of sand addition to an intertidal for the development of the Manila clam habitat on benthic community structure. For this, we focused on the spatio-temporal changes in the surface sediment condition and benthic community structure before and after the event. Study site was an sandbank in Gonam-myeon, Taean-gun where sand added to on July 2010. We set three stations at each of sand adding area (experimental plot) and non sand-adding area (control plot) and did sampling works ten times from June 2010 to October 2011. Directly after the event, surface sediments changed to very coarse sand, but the state was not maintained over four months because of seasonal sedimentation and finally got back to very fine sand in eight months. The number of species and density were temporarily reduced right after the event and crustacean species such as Apocorophium acutum, Photis sp. were most negatively affected by the event. However, the number of species recovered from the reduction in three months and density did in four months due to the recolonization by the existing species and species in the vicinity of the plot. During the study period, dominant species continuously changed from the species such as A. acutum, Photis sp. at the time before the event, through the species such as Heteromastus filiformis, Macrophthalmus japonicus at the time right after the event, to the species such as Musculista senhousia, Ruditapes philippinarum, Mediomastus californiensis in the latter part of the study period. Although surface sediment properties and ecological indices recovered within a certain period after the event, the recovery of community structure has never been observed up to the end of the study.

In an attempt to improve the substrate condition for Manila clam (Ruditapes philippinarum) culture, crushed oyster (Crassostrea gigas) shells were spread on the muddy tidal flat of Namseong-ri, Podu-myeon, Goheung-gun, Jeollannam-do in April 2008. To test the suitability of the crushed oyster shell added substrate, seed clams were transplanted from Taehwa river estuary in Ulsan city in June 2008. Over 23 months of sampling, the mean grain size and the sorting in the experimental site containing the crushed oyster shell were significantly higher than the control site. The ignition loss, water content, chemical oxygen demand (COD) and acid-volatile sulfide (AVS) level were also significantly higher in the crushed oyste shell added substratum. Survival of the clams transplanted to the crushed oyster shell added substratum was significantly higher and all the clams transplanted to the normal muddy substratum died in August 2009, 13 months after the transplantation. At the end of the experiment in April 2010, the transplanted clams reached 36.10 mm in shell length and 8.92 g in total weight with survival of 43.5%. Our study suggested than crushed oyster shell added in the mud dominant substratum greatly improved living condition and survivability of clams. 2008년 4월에 전남 고흥군 포두면 남성리 지선에서 바지락이 서식하기 어려운 니질의 양식장에 폐기물로 처리되는 굴 패각을 분쇄하여 넣어준 후, 2008년 6월에 울산 태화강에서 채취한 바지락 종패를 씨뿌림하여 양식 가능성 여부를 조사하였다. 조사해역 저질의 입도분석에서 굴 패각을 넣어준 시험구에서 대조구에 비하여 평균 입도와 평균 분급도는 증가한 것으로 나타났다. 또한 퇴적물에서도 산휘발성황화물 (AVS), 화학적 산소요구량 (COD), 강열감량 (IL), 함수율이 굴 패각 시험구에서 증가한 것으로 나타났다. 굴 패각을 이용한 바지락 양식장 저질개선 후, 2008년 6월에 평균 각장 21.00 mm, 전중량 1.86 g을 씨뿌림하였다. 23개월이 경과한 2010년 4월에 굴 패각 시험구에서는 각장 36.10 mm, 전중량 8.92 g으로 성장하였으며, 최종 생존율은 43.5%로 나타났다. 그러나 굴 패각을 넣지 않은 대조구에서는 13개월이 경과한 2009년 7월에 각장 32.62 mm, 전중량 7.34 g으로 성장은 빠르게 나타났으나, 모두 폐사하는 결과를 나타냈다.

2002년 6월부터 2003년 10월까지 충남 태안군 안면읍 내파수도 연안의 수하식 양식장에서 비단가리비 치패 (평균 각고 $32.97{\pm}6.21mm$, 전중량 $5.63{\pm}3.86g$) 를 채롱에 수용하여 밀도에 따른 성장과 생존을 연구하였다. 비단가리비는 주로 한국의 서해안과 중국의 북부 연안에 자연적으로 서식하는 종이다. 조사해역의 표층 수온은 $4.3-25.3^{\circ}C$, 염분은 29.2-32.1 psu, 용존산소는 5.32-7.51 mg/L이었고, pH는 7.84-8.12로 나타났다. 실험을 시작할 때 채롱 당 수용밀도는 20, 30, 40, 50 개체로 하였다. 실험을 시작하여 16개월이 경과한 후의 평균 각고는 64.35-76.23 mm였고, 전중량은 41.53-64.85 g, 생존율은 82-100%로 나타났다. 비단가리비의 성장률은 수용밀도와 역상관 관계를 가지고 있었다. 각고와 전 중량의 성장은 수온이 하강하면서 감소하였다. 비단가리비의 폐사는 대부분 3-4월과 9-10월에 나타났다. 밀도에 따른 생존율은 밀도가 증가함에 따라 감소하였으며 20마리 실험구에서 가장 높게 나타났다. We studied that the effect of stocking density on growth and survival rate of the scallop, Chlamys farreri (initial shell height 32.97 mm and total weight 5.63 g) from June 2002 to October 2003 in the west coast of Korea. C. farreri is usually the west coast of Korea and northern China in the natural habitat of the coastal species. Range of surface water temperature in the study area was $4.3^{\circ}C$ to $25.3^{\circ}C$, salinity 29.2 psu to 32.1 psu, dissolved oxygen 5.32 mg/L to 7.51 mg/L and pH was 7.84 to 8.12, respectively. The stocking densities were 20, 30, 40 and 50 individuals per a compartment of suspension cage in culture beginning. After 16 months from initiation, ranges of shell height and mean total weight were from 64.35 mm to 76.23 mm and from 41.53 g to 64.85 g. The survival rate was from 82% to 100%. The growth rate of the scallop was negatively correlated with the stocking density. The growth of the shell height and total weight were decreased with decreasing of water temperature. Most of mortality of scallop occurred during March to April and September to October. Survival rate in the stocking density was decreased by density increase and was highest in 20 individual a compartment.

2005년 9월부터 2006년 10월까지 충남 태안군 안면읍 내파수도 지선의 수하식 양식장에서 비단가리비 치패 (평균 각고 $38.6{\pm}6.8mm$, 전중량 $7.2{\pm}4.9g$) 를 채롱의 망목과 재질에 따른 성장과 생존율을 연구하였다. 실험에 사용한 채롱의 망목은 1 cm와 2 cm, 재질은 경심망과 플라스틱의 두 종류였으며, 채롱 당 수용밀도는 동일하게 30마리로 하였다. 실험을 시작하여 13개월이 경과한 후 평균 각고는 69.7-73.9 mm였고, 전중량은 36.1-47.0 g으로 나타났다. 생존율은 93-100%로 높게 나타났으며, 비단가리비의 성장률은 채롱의 망목과 상관관계를 가지고 있었다. 채롱의 재질에 따른 성장률은 2005년 9월부터 2006년 6월까지는 경심망 채롱보다 플라스틱 채롱에서 빠르게 나타났으나, 2006년 6월부터 10월까지는 부착생물에 의한 먹이섭취 방해로 플라스틱 채롱에서 경심망 채롱보다 느리게 나타났다. We studied that the effects of mesh size and material of cages on the growth of C. farreri (initial shell height 38.6 mm and shell total weight 7.2 g) held in suspension cage from September 2005 to October 2006. The experiment was performed with two mesh sizes (1 cm and 2 cm) and two materials (net and plastic) of cages in same densities. After 13 months from culture beginning, ranges of shell height and total weight were from 69.7 mm to 73.9 mm and from 36.1 g to 47.0 g, respectively. The survival rate was from 93% to 100%, respectively. The growth rates of the scallop were positively correlated with the mesh size. In the growth rate according to culture material, the growth of scallop in the plastic cage was faster than that in the net cage from September 2005 to June 2006, but the growth in the plastic was slower than that in the net cage for obstruction by attaching organisms from June to October 2006.

It is well known that one of the major causes of acute hemolytic transfusion reaction is clerical error, which can occur in the process of blood preparation, including misidentification of specimens and blood components, data input errors, wrong blood issuing, etc. To minimize the potential risks for clerical errors, Laboratory Information System(LIS) has been used since 1990 in our blood bank. The LIS is a computerized system which control ever step from blood ordering at the ward to laboratory tests and preparation and issuing of blood components in blood bank. When the order for blood components is input at the ward, the order list is printed by the printer in blood bank simultaneously. The process of blood components preparation in blood bank can be checked at the wards by the Order Communication System(OCS). Barcode reading can minimize the risks for manual input errors. If any mismatch or errors occur during the procedure, a warning message appear in the screen to check it out. In conclusion, we have exploited the LIS for blood bank processes, which is useful to prevent the risks for clerical errors

Purpose: We report short-term results of radial head prosthesis using a unipolar loose fit stem in ten patients. Materials and Methods: Ten patients with Mason type three radial head fracture, who received unipolar radial head arthroplasty from February 2010 to June 2011, were evaluated (mean follow-up: 22 months, range: 18-30 months). Subjects consisted of five men and five women. Range of elbow motion was measured. Mayo elbow performance index (MEPI) score was used for functional evaluation and periodic radiological imaging was performed to evaluate the stability of implant. Results: After an average follow-up of 22 months, elbow stability was maintained in all cases, and the average range of motion of elbow flexion and extension was 6 to 130 degrees. Average range of pronation and supination was 66 and 74 degrees, respectively. MEPI score was evaluated as excellent in seven cases, and good in three cases. On final follow-up, radiological assessment showed implant stability in all cases without evidence of dislocation, subluxation, arthritis, periprosthetic osteolysis or heterotopic ossification. Conclusion: Based on our short-term follow-up, radial head arthroplasty with unipolar loose fit stem is a useful method for obtaining satisfactory outcome for unreducible comminuted radial head fractures.
