Purpose: To report a case of candida infection after Medpor<sup>® orbital implantation. Methods: A 51-year-old man was admitted complaining of painful swelling and discharge about 3 years after orbital Medpor<sup>® implantation. External examination revealed signs of infection and exposure of the implant. Medpor<sup>® was surgically removed. In laboratory studies, white colony was detected in blood agar, potato dextrose agar, and CHROMagar. Automatic identification with yeast standard test revealed Candida parapsilosis. Results: Six months after surgery, the wound had healed well. In addition, cosmesis was acceptable with the artificial eye, except mild superior sulcus deformity. Conclusions: Although rare, fungal infection of the implant should be suspected when there are the long standing signs of infection and exposure after orbital Medpor<sup>® implantation.

그리니치와 본초자오선

윤경철 한국지도학회 2004 한국지도학회지 Vol.4 No.1

테임즈강 하구에 발달한 그리니치는 천문관측의 요람으로 알려져 있다. 16세기부터 새로운 땅을 찾아 나아가던 사람들이 안전한 항해기법을 발견하기 위하여 갖은 노력을 한 본거지이다. 초기에는 천문대를 설립하면 천문학적인 방법으로 경도를 발견하여 안전한 항해를 할 수 있을 것으로 믿었지만 그 꿈은 허사로 돌아가고 말았다. 결국 무명의 해리슨이 정확한 해상시계(chronometer)를 발견함으로서 경도측정방법을 제시하였다. 오늘날 "그리니치=본초자오선"이라는 등식으로만 알고 있는데, 그리니치가 본초자오선. 즉, 지구의 기준선이 되기까지의 과정을 이해함으로서 지리 및 지도제작과 측량분야에 좀더 가까이 다가설 수 있다고 생각된다. 경도측정방법의 발견과 더불어 본초자오선의 결정, 그리고 세계의 시간시스템의 기준도 그리니치로 결정되어 있다. 그러므로 그리니치는 시공간적으로 세계의 기준이다.

Purpose: To evaluate the clinical effect of AlloDerm? graft on the management of exposed hydroxyapatite orbital implants. Methods: Seven eyes of 7 patients with large exposure of hydroxyapatite orbital implants were included. After the spicules of hydroxyapatite implants were smoothened with a drill, AlloDerm? was applied to the exposed site and sutured with 8-0 Vicryl. One or two layers of amniotic membrane were transplanted on the AlloDerm? graft. Results: All patients underwent the drilling, and the mean intervals from drilling to exposure was 73.4±46.6 months. The mean follow-up period was 11.17±2.0 months (range, 9-14 months). Complete conjunctival epithelization occurred in 3 eyes, and partial conjunctival epithelization in 3, including one eye which underwent reoperation with AlloDerm?. In one eye which had been associated with previous infection, hydroxyapatite was removed due to progressive exposure and inflammation of the implant. Conclusions: AlloDerm? graft is useful in the management of exposed hydroxyapatite implant.

수도권 철도역 광역환승센터 및 연계시설의 재원분담 방안

윤경철,김시곤,김진태 대한토목학회 2017 대한토목학회논문집 Vol.37 No.1

In this paper, the current financial resource allocation principle and issues are studied in the beginning for the metropolitan transfercenters and connection transport facility. In addition to this, foreign cases for this matter are performed for the USA and Japan. Basedon the foreign cases, the optimal subsidy ratio of central government is suggested. For the metropolitan transfer centers, at least 50%of subsidy is required from 30% at present and from “necessary costs” to “total costs.” For connection transport facility, 50% for road facility and 70% for railway facility are proposed, which is not supported at all at present. As far as connection transport facility are concerned, resources allocation scheme between local governments has also been proposed in the proportional to the length of connection transport facility of each local government. 본 논문에서는 철도역 광역환승센터 및 연계시설의 재원분담 현황과 문제점을 분석하였다. 아울러 해외의 미국과 일본의 재원분담 기준을 검토하였다. 이를 기반으로 철도역 광역환승센터와 연계시설에 대한 중앙정부의 적정 재정분담을 제시하였다. 광역환승센터의 경우 대중교통 중심의 교통체계를 구축하기 위해서는 국고지원 비중을 현재 30%에서 50%이상으로 확대하고 지원대상도 환승센터의 구성시설을 넘어 환승센터로 지정된 부지 및 환승시설 모두를 포함 시켜야 한다. 연계시설은 연계도로는 50%, 연계철도는 70%를 지원하는 분담방안을 제안하였다. 또한 지자체간 재원분담 방안은 관련법에 분담기준이 없어 연계시설의 노선연장 비율에 따라 분담금액을 산정하는 방안을 제안하였다

Purpose: To evaluate the clinical effect of photodynamic therapy (PDT) with verteporfin (Visudyne?, Novartis Ophthalmics AG, Hettingen, Switzerland) in the treatment of corneal neovascularization. Methods: We performed photodynamic therapy on one eye with corneal neovascularization associated with lipid keratopathy, and on another eye with corneal neovascularization after corneal perforation. Verteporfin was administrated intravenously for 10 minutes at a dose of 6 mg/m2 of body surface area. Fifteen minutes after the start of administration, a 689 nm nonthermal laser light (Opal photoactivator, Coherent Inc., USA) was delivered directly over the neovascular network for 83 seconds with a spot size of 4000 μm. The patients were followed up at 3 days, 1 week, 1 month, and 6 months after treatment. Results: In both cases, new vessels were successfully occluded after the photodynamic therapy. No recanalization of new vessels was observed at last follow-up and no complications were observed. Conclusions: PDT with verteporfin is considered to be a safe and effective procedure to regress corneal neovascularization.

Purpose: To investigate the efficacy of fibrin glue for conjunctival autotransplantation in pterygium. Methods: Forty eyes of 32 patients who underwent conjunctival autotransplantation for primary pterygium with a minimum follow-up period of 6 months were included. Postopertive pain, foreign body sensation, tearing, subconjunctival hemorrhage, surgery time, complication, and recurrence were evaluated prospectively in 20 eyes of 15 patients undergoing surgery with fibrin glue, and in 20 eyes of 17 patients undergoing surgery with sutures. Results: One day postoperative, the scores of pain (P<0.01), foreign body sensation (P<0.01), tearing (P<0.01), and subconjunctival hemorrhage (P=0.01) were significantly lower in the fibrin glue group than in the suture group. One week postoperative, the scores of foreign body sensation (P=0.01) and tearing (P=0.01) were significantly lower in the fibrin glue group than in the suture group. Mean surgery time in the fibrin glue group (18±8 minutes) was significantly shorter than in the sutures group (32±11 minutes) (P<0.01). There was no significant difference in the recurrence rates of the two groups. Conclusions: Use of fibrin glue for conjunctival autotransplantation in pterygium can reduce postoperative discomfort and required surgical time.
