장민호,조가익,하진용,정광석,박성배,주기재 한국어류학회 2002 韓國魚類學會誌 Vol.14 No.4

설악산 국립공원지역 산간계류의 17개 지점에서 2000년 6월부터 2001년 6월까지 어류상 및 이화학적 요인을 계절별로 총 4회에 걸쳐 분석하였다. 모든 조사지점은 1~3차의 하천으로 비교적 물리·화학적 교란이 적었으며 하천폭은 5~30 m 정도였다. 채집된 어류는 총 18과 42종 2,557개체였고, Cyprinidae는 16종으로 84.7%의 상대풍부도를 나타냈으며, Gobiidae 4종, 5.0?의 상대풍부도를 보였다. Cyprinidae는 전체 채입종의 37.2%를 나타냈다. 우점종은 Zacco temminck로 10개 지점에서 738개체가 채집되어 28.9%의 상대풍부도를 나타냈으며, 아우점종은 Rhynchocypris kumkangensis와 Z. platypus로 각각 4개 지점 648개체(25.3%)와 7개 지점 344개체(13.5%)로 나타났다. 한국고유종(Korean endemic species)은 모두 4과 11종 781개체로 30.5%의 상대풍부도를 나타냈으며, 고유화 빈도는 25.6%로 한국의 평균 고유화 빈도와 유사하게 나타났다. 본 조사에서 외래어는 채집되지 않았다. 국립공원 내에 서식하는 어류의 다양성 유지와 회복을 위해서는 공원 내는 물론 경계지역 하천의 체계적인 관리가 요구된다. The fish fauna of mountain streams in the Seorak National Park area was investigated from June 2000 to June 2001 (4 times). All 17 sites were relatively undisturbed 1st to 3rd order streams. A total of 2,557 individuals were collected and classified into 17 families and 43 species. Cyprinidae accounted for 37.2% (16 species) of the total fish species and 84.7% (2,165 ind.) of the total abundance. Subdominant families were Gobiidae (4 species, 5.0%) and Balitoridae (3 species, 3.4%). Zacco temmincki (RA 28.9%, 10 sites) dominated. Subdominant species were Rhynchocypris kumkangensis (25.3%, 4 sites) and Zacco platypus (13.5%, 7 sites). Eleven of the species are endemic to Korea (4 families, 30.5%). Exotic species were not collected in this survey. Fish diversity was higher in streams around the boundary area than in the national park. Therefore, management of streams in the boundary area to protect the fish biodiversity can be efficiently conducted. Habitat degradation should be reduced for the conservation and restoration of fish diversity.

배경 : MRSA, VRE, VRSA같은 다제 내성 그람 양성균의 등장에 따라 glycopeptide를 대체할 새로운 항생제의 개발이 필요하게 되었고 결과적으로 새로운 항생제인 linezolid라는 항생제가 개발되었다. Linezolid는 이전의 항생제와는 다른 새로운 계열의 oxazolidinone으로 경구 이용률이 우수하다. 원내 및 원외감염의 중요한 원인균이 되고 있는 MRSA, VRE에 대한 적절한 경구용 항균제가 없는 국내에서 폐렴 및 피부 연조직 감염에서 경구용으로 사용해 볼 수 있는 약제이다. 본 연구에서는 고대 구로 병원에서 분리된 MRSA, VRE 등을 대상으로 다른 여러 항균제와 비교한 linezolid의 시험관내 항균력을 조사하고자 하였다. 재료 및 방법 : 연구대상은 1998년 1월부터 2000년 12월까지 본원에서 입원 및 외래를 통하여 피부 연조직 감염증 및 호흡기 감염증, 요로감염증으로 진단된 환자들의 가검물로부터 분리된 MRSA 60균주, VRE 43균주, PRSP 25균주를 액체배지 또는 한천배지 희석법을 통하여 linezolid 및 기타 항균제에 대한 최소발육억제농도를 구하였다. 결과 : 실험에 사용한 S. aureus는 모두 MRSA였고 이들은 linezolid에 대해 MIC_(90) 2㎍/㎖(MIC 범위 1-2㎍/㎖), Enterococcus spp는 모두 VRE로 linezolid의 MIC_(90)은 2㎍/㎖로 MIC 범위는 1-4㎍/㎖였다. 한 개의 균주에서 MIC 4㎍/㎖로 중등도 감수성을 보였으나 MIC breakpoint가 (8㎍/㎖인 내성균주는 없고 모두 감수성을 보였다. S. pneumoniae의 경우 penicillin 내성이었고, linezolid MIC_(90) 1㎍/㎖ (MIC 범위 0.5-1㎍/㎖)로 전부 감수성을 보였다. 결론 : Linezolid는 MRSA를 위시한 VRE, PRSP 등의 다제 내성 그람 양성균에 대하여 우수한 시험관내 항균력을 보임을 알 수 있었다. Background : The emergence of multi-drug resistant Gram-positive cocci, such as MRSA, VRE, and VRSA, necessitated to develop new antibiotics, which could replace the glycopeptide. As a result, a new antibiotics named linezolid was developed. Linezolid is different line of oxazolidinones with a good oral bioavailability, compared to other antibiotics. Since appropriate oral antibiotics are not presently available for MRSA, which is a major cause of nosocomial and community acquired infections, the introduction of linezolid will have favorable effect on treatment of infections such as pneumonia or skin infections. In this study, we investigated the antibiotic effect of linezolid on MRSA and VRE isolated from patients who were treated in Korea University Guro Hospital. Material and Methods : By using broth microdilution and agar dilution method we measured minimum inhibitory concentration (MIC) with sixty S. aureus, forty three Enterococcus spp., and twenty five S. pneumoniae isolates from patients who were diagnosed as skin, soft tissue, respiratory, and urinary infections in Korea University Guro Hospital from January, 1998 to December, 2002. Results : All of S. aureus used in this study were MRSA, and MIG_(90) of linezolid was below 2 ㎍/㎖ (MIC ranged between 1-2 ㎍/㎖). All of Enterococcus spp. were VRE, and had MIG_(90) of 2 ㎍/㎖ (MIC ranged between 1 to 4 ㎍/㎖). One of the VRE showed intermediate susceptibility with MIC of 4 ㎍/㎖. However, none was resistant with MIC breakpoint above 8 ㎍/㎖. All of S. pneumoniae were resistant to penicillin, but they were susceptible to linezolid with MICao of 1 ㎍/㎖(MIC range 0.5-1㎍/㎖). Conclusion : In conclusions, linezolid has an excellent in vitro antibiotic effect on multi-drug resistant Gram-positive cocci, such as MRSA, PRSP, and VRE.

Purpose: BOOP and NSIP also share similar clinical features such as subacute flu-like illness, the finding of bronchoalveolar lavage, the result of pulmonary function test and more favourable outcome than usual interstitial pneumonia(UIP). The author try to compare the HRCT findings of NSIP with BOOP by pattern and distribution of diseases. Materials and Methods: HRCT findings of histopathologically proven NSIP(Group Ⅰ; 6, Group Ⅱ; 7, Group Ⅲ; 2) in 15 patients(5 male, 10 female, age range, 39-69 years; mean age, 53 years), BOOP in 15 patients(6 male, 9 female, age range, 26-76 years; mean age, 52 years) were reviewed retrospectively. Results: The common pattern of the two diseases was admixed consolidation, ground glass attenuation & reticular densities with/without architectural distortion(NSIP; 53.3%, BOOP; 46.7%). The main component of the pattern wan predominantly consolidation(NSIP; 46.7%, BOOP; 73.3%) and ground glass attenuation(NSIP; 40.0%, BOOP;20.0%). Architectural distotion was more provinent finding with NSIP(mild ; 3, moderate ; 4, severe; 2) compared with BOOP(mild; 7, moderate; 2, severe; 0). The predominant overall distribution was lower lung, peribronchovascular & peripheral lung field in both of the two entities(NSIP;73.3%, BOOP; 73.3%). Peribronchovascular involvement was more common with NSIP(100%) than BOOP(80%), whereas peripheral involvement was more common with BOOP(93.3%) than NSIP(80%). Conclusion: The HRCT findings of NSIP and BOOP were similar in pattern and distribution. But NIP manifested more frequently ground-glass attenuation, whereas BOOP showed more frequently consolidation. Architectural distortion was more severe with NSIP than BOOP. NSIP invoved more frequently peribronchovascular space and BOOP were more common in peripheral lung field.

Hence, the control module controls angle of camera to turn upward from the bottom to monitor vehicle surroundings. The image processing module merges the received images from cameras with the original vehicle image to display the vehicle’s surroundings in real time as if looking down from the sky.

지상라이다를 이용한 미기록 외래종 갯쥐꼬리풀(Spartina Alterniflora)의 분포특성과 관리방안 연구 -다도해 해상국립공원 진도 남동리 해안을 사례로-

박정원 ( Jung Won Park ),김하송 ( Ha Song Kim ),장성건 ( Seong Geon Jang ),천숙진 ( Sook Jin Chun ),육관수 ( Kwan Soo Yuk ) 한국도서학회 2015 韓國島嶼硏究 Vol.27 No.3

갯쥐꼬리풀(Spartina alterniflora)은 북미 대서양 연안 뉴펀들랜드, 캐나다 남쪽에서 아르헨티나 북부의 갯벌이 원산이며, 생장이 강한 특성으로 세계의 기수지역과 해안에서 생태공학적 용도로 도입된 바 있다. 그러나 매우 빠르게 갯벌을 피복하여 자생종의 생장을 방해하고, 염습지 종다양성을 감소 시켰고, 결과적으로 과다생육으로 갯벌 무척추동물의 서식지를 잠식해 사라지게 하여 무척추동물을 먹이로 하는 조류 또한 생태계 내에서 감소키는 등 많은 환경문제를 야기 시켰다. 우리나라에서는 2008년 전후에 다도해해상국립공원에 유입된 것으로 판단된다. 현재 다도해해상국립공원 남동리 해안에서 분포하고 있는 갯쥐꼬리풀(Spartina alterniflora)군락은 습지내 총 6개의 염생식물 군락면적(8,487.7㎡) 중 75.34%의 비율(6,394.86㎡)로 분포하고 있다. 또한 2008년에 11.54㎡ 이던 분포 면적이 2015년 현재 약 550배가 늘어난 6,394.22㎡로 조사되었고 생육지 고도 범위인 0.69m~1.1m를 요인 값으로 두고 GIS 분석한 하였다. 그 결과 앞으로 확산 될 예상 면적은 12,584㎡이며 현재보다 약 6,189.14㎡가 늘어날 것으로 예측되며 우리나라에서도 역시 확산이 빠르고 넓게 늘어날 것으로 판단된다. 향후 계속 분포역이 확대 될 것으로 예상하고 관리방안을 위하여 시범 연구를 실시하였다. 갯쥐꼬리풀군락 중 일부를 첫 번째는 뿌리째 뽑아내기와 두 번째 지상부 제거 후 포장덮기 방법 등 국외사례의 문헌을 바탕으로 방재를 실시하였으나 전체 면적을 방재하기에는 많은 인력과 시간 그리고 예산이 소요되므로 다각적인 방안을 강구하여야 한다. Spartina alterniflora is native to the Atlantic coast from Newfoundland, the south of Canada and northern Argentina. There it forms a dominant part of brackish coastal saltmarshes. Due to its strong growth, the Spartina alternifolra was introduced to the rider area and coast as a use for ecological engineering. The Spartina alterniflora community can crowd out native species, reduce the biodiversity of saltmarsh and alter the environment. As a result, the invertebrates living in mud flats disappeared due to the encroaching of Spartina alterniflora, and the birds which eat off invertebrates went along as well. The Spartina alterniflora was first introduced in South Korea in 2008 and is known to have flowed in the Dadohaehaesang National Park. Compared to 2008, in 2015 the distribution area of the Spartina alterniflora has increased 550 times. (11.54㎡ in 2008 to 6,394.22㎡ in 2015). The large increase of Spartina alterniflora calls for urgent management and additionary study on the subject. Thus, this study analyzed the geo-spatial information on the Spartina alterniflora such as its distribution area, the height of habitats and expected expansion area, and can act as the preliminary data for management.

도시자연공원의 주요 등산로 훼손실태 분석 - 대구광역시 앞산공원을 대상으로 -

박인환,이혜영,조광진,장갑수,Park, In-Hwan,Lee, Hea-Young,Cho, Kwang-Jin,Jang, Gab-Sue 한국조경학회 2010 韓國造景學會誌 Vol.38 No.3

본 연구는 대구광역시의 대표적 도시자연공원인 앞산도시자연공원의 주요 계곡인 큰골, 안지랑골, 매자골의 주요 등산로를 대상으로 등산로의 훼손현황, 주연부 식물상을 조사하여 훼손유형분류에 따른 복원방안을 도출하여 보다 쾌적한 도시자연공원이 되도록 기초자료를 제공하고자 실시하였다. 앞산을 중심으로 조사한 3개의 등산로의 총 9km, 69개 지점에서 등산로 상태를 조사한 결과, 평균등산로 폭이 2.0~2.6m, 뿌리노출이 2,108m(23.4%), 암석노출이 3,199m(35.5%), 노면침식이 3,280m(36.6%), 토양경도가 강견($2.5kg/cm^2$)으로 4,841m(53.8%), 훼손발생지역이 83곳으로 훼손이 심각한 것으로 나타났으며, 등산로 주연부에서 확인된 식물상은 총 79과 206속 306종이었다. 귀화율과 도시화지수는 인간간섭의 정도와 강도를 나타내는 하나의 지표로서 큰골이 각각 7.0%, 5.5%, 안지랑골이 각각 8.3%, 4.5%, 매자골이 각각 8.6%, 6.2%, 전체가 각각 7.8%, 8.3%로 나타났다. 등산로 주변으로 확산되는 훼손의 진행단계와 범위를 파악하기 위한 환경피해도는 5등급 이상의 비율이 큰골이 24.3%, 안지랑골이 17.1%, 매자골이 21.6%로 큰골이 피해가 가장 심했으며, 큰골, 매자골, 안지랑골의 순으로 피해가 심하게 나타났다. 본 조사구간의 환경피해도 결과를 보면 등산로는 이용과밀로 인한 침식과 뿌리노출, 암석노출의 훼손현상이 일어나면서 등산로의 훼손이 점점 심각해지고 확산될 수 있다는 의미로 해석할 수 있다. 따라서 현재의 상태를 방치할 경우 침식이 가속화 될 뿐 아니라 뿌리노출, 암석노출, 노폭확산 등의 피해가 잇따르므로 침식구간의 정비가 시급한 것으로 판단된다. Many trails have been built and utilized in each sub-basin of Apsan Park. This study focused on the conditions and the present flora of several overused trails within three basins called Kun-Gol, Anjiroung-Gol, and Meaja-Gol in Apsan Park. There are two purposes for this study. The first is to make a plan for restoration by classifying the type of damage to these overused trails. The second is to provide preliminary data for reestablishing a more pleasant urban nature park. As a result of the survey, the average length of these trails is 9.0km and mean width is 2.0 to 2.6m. 2,108m of the sections studied(23.4% of the total) had exposed root, 3,199m of the sections studied (35.5% of the total) had exposed rock, 3,270m of the sections studied(36.6% of the total) displayed damaged pathways, and 4,841m of the sections studied (53.8% of the total) had higher soil hardness. Eighty-three areas of deterioration were found and there has been extensive property destruction. As an indication of human disturbances, the Naturalization Index and Urbanization Index appeared as: Kun-Gol, 7.0%, 5.5%; Anjiroung-Gol, 8.3%, 4.5%; Meaja-Gol 8.6%, 6.2%; in total, 7.8%, 8.3%. As a method of checking the level and extent of the damage process, an impact rating classification was used at each point on the trails. Kun-Gol had the highest rating and Anjiroung-Gol had the lowest rating in impact rating classification. With the impact rating classification, it was found that each trail would continue to worsen, meaning that roots and rocks are more likely to be further exposed and the trail width will continue to widen through overuse. An actual plan for reparations and restoration of the trails is needed through further study.

박재성,백상현,차장규,홍현숙,김대호,박성진,조준희,임한혁,이혜경 순천향의학연구소 2003 Journal of Soonchunhyang Medical Science Vol.9 No.2

Purpose : To determine the diagnostic accuracy and predicting factor of pneumothorax on CT-guided percutaneous transthoracic needle biopsy. Materials and Methods : Using automated biopsy devices, 107 CT-guided percutaneous needle biopsies of pulmonary lesions were performed. Final diagnosis was made with operation or other methods. We retrospectively analyzed the frequency of complications and diagnostic yields of 107 biopsies. The clinical features, treatment, and courses of complications were reviewed, and risk factors of pneumothorax such as depth and size of lesion, CT emphysema score of whole lung and pathway of needle, and the result of pulmonary function test were analyzed. Result : 96 biopsies(89.7%) yielded sufficient tissue for pathologic evaluation. For cases of malignant and benign disease, sensitivity was 91.5% and 87.5% respectively; the corresponding figures for diagnostic accuracy were 88.1% and 77.1%. So, sensitivity and diagnostic accuracy of percutaneous transthoracic needle biopsy was 89.7% and 83.2%. Eighteen(16.8%) of 107 patients developed pneumothorax and 3 of these required application of chest tube or percutaneous catheter drainage. In the group with pneumonthorax, the lesion was significantly smaller(p=0.029) and higher CT emphysema score of pathway of needle(p=0.032). But there were no significant difference between two groups(with or without pneumothorax) for depth of lesion, pulmonary function test(% predictive value of FEV1 and FEV1/FVC) and CT emphysema score of whole lung. Conclusion : CT-guided transthoracic needle biopsy of the pulmonary lesions is safe and easy method of obtaining specimens of good quality and quantity. It may be an useful procedure in the diagnosis of localized pulmonary lesions. For the prediction of pneumothorax, size of lesion and CT emphysema score of pathway of a needle are significant risk factors.
