본 연구는 cadmium의 축적균주인 Pseudomonas maltophilia H-8을 MNNG로 처리하여 cadmium축적능이 가장 우수한 변이균주인 Pseudomonas maltophilia H-8M을 얻었고 그 특성을 조사하였다. 변이주 Pseudomonas maltophilia H-8M은 카드뮴농도 1,000ppm에서 36시간 배양했을 시 대조구에 비해 약 80%정도의 성장율을 나타내었다. 카드뮴 이외의 중금속의 첨가에 따른 생육상은 Pb^(2+), Zn^(2+), Hg^(2+), Cu^(2+), Cr^(2+), Co^(2+)등에는 별다른 성장 억제는 없었으나 Sn^(2+)에서는 생육억제가나타났다. 또한 50ppm의 카드뮴을 배지에 첨가 하였을 때 균체내 카드뮴 축적율은 52.92%로 가장 높게 나타났으며 축적부위는 세포벽에 80.3%의 축적율을 나타내었다. This study was carried out to investigate the characteristics of a mutant, Pseudomonas maltophilia Ho8M selected with the treatment of Pseudomonas maltophilia H-8 by N-methyl-N-nitro-N-nitrosoguanidine (MNNG). This mutant showed highest ability of cadmium accumulation. The growth rate of Pseudomonas maltophilia H-8M showed about 80% in 1000ppm Cd containing medium when compare with control for 36h at 30℃. Pseudomonas maltophilia H-8M not inhibited on the growth in addition of various heavy metal such as Hg^(2+), Zn^(2+), Pb^(2+), Cu^(2+), Cr^(2+) and Co^(2+), but inhibited in Sn^(2+) containing medium, respectively. Pseudomonas maltophilia H-8M was accumulated the highest cadmium level of 62.3% on whole cell in the medium containing 50 ppm and 80% of accumulated cadmium was distributed in the cell wall.

현대의 도시는 살아있는 생명체처럼 매일 변화를 거듭하고 있다. 이전과 달리 집중된 공간에서 짧은 시간동안 일어난 공간의 변화는 도시환경을 악화시켜 환경문제를 유발하였다. 특히 지표면 및 토지이용의 변화 등으로 발생된 도시열섬현상은 도시민의 건강과 경제적인 손실 등 사회문제로 대두되고 있다. 이러한 도시열섬현상을 해결하기 위한 도시계획적 접근방법의 하나가 녹지네트워크의 도입이다. 본 연구에서는 대구광역시 중구와 남구를 사례대상지로 선정하여 도시열섬현상 분석, 토지피복분류, 녹지네트워크 연계가능성 분석, 바람길 분석을 통하여 녹지네트워크 구축을 제안하였다. 연구결과 남쪽의 앞산 및 산지지역을 녹지네트워크의 핵, 두류공원 및 달성공원 등 남구 2개 지역과 중구의 6개 지역의 근린공원을 거점으로 하고 학교부지와 공원시설 등을 포함하는 지역을 거점 가능지역으로 설정하여 대상지역의 광역 및 세부 그린네트워크 구축을 제안하였다. 특히 앞산과 연결되는 캠프워커는 핵과 연결되고 있는 거점지역으로서 향후 미군부대 이전 후에 반드시 보전되어야 할 지역으로서 판단된다. 또한 녹지네트워크를 통해 바람길을 확보하기 위하여 중구의 수성교 인근과 남구의 캠프워커지역을 바람통로확보지구를 설정하는 것이 바람직할 것으로 판단된다. Like other organic beings, modern cities change every day. Unlike in the past, changes of space which have been taking place in concentrated spaces during short periods of time have worsened the environment of cities creating environmental problems. In particular, the urban heat-island phenomenon, which is caused by changes in using the earth`s surface, has emerged as a key social issue along with health problems and economic difficulties. The Green Network has been introduced as an urban planning approach to solve the urban heat-island phenomenon. This study suggests constructing a Green Network through analyzing the urban heat island phenomenon, land cover classification, and linkage possibility with the Green Network and wind corridors by researching Jung-Gu, and Nam-Gu in Daegu Metropolitan City. In conclusion, this study presented the construction of a broad and detailed Green Network of object areas by assigning Apsan to the southern area and mountain area as the core, two areas of Nam-Gu and six areas of Jung-Gu such as Duryu Park and, Dalsung Park as footholds and other school land and park facility areas as footholds-to-be areas. In particular, Camp Walker, which is connected with Apsan, is not only a foothold but connected to the core, is necessary to preserve after being transferred from the U.S. Army. In addition, assigning the Susung Bridge area of Jung-Gu and the Camp Walker area of Nam-Gu as the wind corridor areas is recommended.

Bronchopleural fistula and chronic empyema are the difficult problems in the thoracic surgery field. We experienced 3 cases of chronic empyema and complicated bronchopleural fistulas treated with muscle flap and concomitant thoracoplasty. The causative primary diseases were pulmonary tuberculosis and bronchiectasis. All the three cases have failed to control the chronic empyema and bronchopleural fistula with conventional method such as closed or open drainage and Eloesser flap after lobectomy. The unresponsive infection on bronchopleural fistula and pleural space was well controlled after muscle flap with thoracoplasty. Complete decortication, closure of bronchopleural fistula as much as possible and coverage of closed fistula with good vascularized tissue are the essential factors for the success of operation on chronic empyema and bronchopleural fistula. The results of operations were satisfactory and the respiratory function was well preserved or improved in one patient. But, the contour of chest wall was deformed in patient with extensive concomitant thoracoplasty.

본 증례에서는 치아외상으로 치관-치근 파절된 미성숙 영구치의 치료에 대해 서술하고자 한다. 7세 환아의 상악 좌측 중절치의 치아 파절선이 치은연하로 치아장축을 따라 치아전체의 1/2까지 연장되어 있었다. 수직적 치관-치근 파설된 치아에서 그 예후는 불량하며 발치가 일반적인 처치이나 성장기 아동에서 상악중절치의 발치는 치조골 흡수, 심미적 문제, 발음문제 등 여러 합병증을 초래한다. 치은연하로 치관-치근 파절된 치아의 치료 방법으로 치은연상만 수복하는 방법과 치은판막을 형성하여 수복하여 주는 방법, 교정력을 이용하여 정출시키는 방법과 수술로써 발치하여 정출시키는 방법 등이 있다. 본 증례에서는 치아를 의도적으로 발치한 후 접착용 레진 시스템을 분리된 치아 파절편을 부착한 후 재식하였다. 1년 동안 관찰한 결과 현재 특이한 임상적 증상은 없으며 심미적으로도 만족할 만하다. 접착용 레진 시스템의 개발과 함께 본 술식은 외상을 많이 받는 혼합 치열기 아동에서 치관-치근 파절된 미성숙 영구치의 한 치료법으로 고려할 수 있다고 생각되어 이에 보고 하는 바이다. This case report describes an uncommon treatment method for crown-root fractured incisor with immature root. A 7-year-old girl was referred for treatment of crown-root fractured maxillary central incisor. The fracture line extended to 1/2 of the total tooth length with incomplete root formation. The prognosis of crown-root fracture is usually poor and extraction is usually undertaken. But, in the mixed dentition, extraction of maxillary permanent incisor results in many complications, such as resorption of alveolar bone, poor esthetics, pronunciation and mastication. Conservative therapy in the permanent dentition comprises of few treatment modalities ; supragingival restoration, gingivectomy, orthodontic extraction of apical fragment, surgical extrusion of apical fragment with or without rotational replantation. However, in this case, these indications are not applicable, so intentional replantation with adhesive resin system is the treatment of choice. The tooth was followed-up for 12 months. Currently, there are no symptoms. Since this modality adopts the respective advantages of both intentional replantation and adhesive treatment, it might be the treatment of choice in cases of vertical crown-root fracture.
