Purpose: To evaluate the success rates according to the shape of rhinostomy after endonasal dacryocystorhinostomy. Methods: We analyzed 131 patients (188 cases) who had undergone endonasal dacryocystorhinostomy with a minimum follow-up of 6 months. After surgery, all cases were classified into flat, alcove, concave, or concealed concave types according to Jane’s rhinostomy classification. Patency to irrigation and improved symptoms were considered indicative of a successful outcome. Results: There were 81 flat type patients (125 cases), 31 alcove type patients (42 cases), 19 concave type patients (21 cases), and no cases were classified as concealed concave type. The success rates were 75.2%, 85.7%, 81.0% respectively, and the most common cause of failure was the formation of granulation within the ostium. The success rates did not significantly vary according to the shape of rhinostomy (p=0.144). Conclusions: The success rates after endonasal dacryocystorhinostomy of flat, alcove, and concave types in turn were 75.2%, 85.7%, and 81.0%.

Purpose: To determine if routine otorhinolaryngologic referral prior to endonasal dacryocystorhinostomy (EN-DCR) is necessary. Methods: Two hundred thirty-seven eyes of 178 patients who were supposed to undergo EN-DCR were prospectively analyzed. Nasal endoscopy was performed by an ophthalmologist and the patients who had severe abnormality were referred to an otorhinolaryngologist. The patients were classified into 3 groups after a preoperative examination by an ophthalmologist and an otorhinolaryngologist; the number and success rate of each group were then investigated. Group A consisted of patients who had no nasal cavity abnormality, Group B consisted of patients with a nasal cavity abnormality but who received no treatment, and Group C consisted of patients who had a nasal cavity abnormality and received otorhinolaryngologic treatment. Results: The number of subjects in each group was 156 in Group A (87.7%), 12 in Group B (6.7%), and 10 in Group C (5.6%). The number of patients who were referred to the otorhinolaryngologist was 22 (12.3%). There was no statistical significance of success rate between the groups. Conclusions: Routine nasal endoscopic examination should be performed by an ophthalmologist prior to EN-DCR. Only patients with severe abnormal findings should be referred to an otorhinolaryngologist as the results from the present study show the percentage of patients having significant nasal abnormalities was found to be low (12%) and the success rate of EN-DCR revealed no statistical significance between the groups. This could help patients by saving time and expense. J Korean Ophthalmol Soc 2012;53(10):1392-1396

Purpose: To introduce the modified Quickert suture for lower lid entropion, using nonabsorbable suture material. Methods: From October, 2011 to June, 2012, a total of 11 patients (12 eyes) with lower lid entropion, in poor general condition or who did not want extensive surgery, were recruited for the present surgery. Three small skin incisions were made at the medial, central, and lateral areas, just below the lower cilia. With double armed 6-0 nylon, each needle was inserted in the inferior conjuctival fornix and the 2 ends of the suture were tied and buried at the point of the skin incision site. Sutures were made at the medial, central and lateral areas. Results: The patients consisted of 4 males and 7 females with an average age of 71.3 ± 8.4 years (54-82 years). The patients were followed up the patients for an average of 13.9 ± 2.4 months postoperatively. All patients were satisfied with the outcome, and there were no recurrences. Conclusions: Quickert suture is a simple and effective method, for correcting lower lid entropion by inducing scar formation with absorbable suture materials, but the effect duration is limited. Because the modified Quickert suture utilizes its own tension with a nonabsorbable suture material, the effect lasts as long as the suture material remains. It is a useful and practicable method for patients, in poor general condition or not wanting extensive surgical procedures. J Korean Ophthalmol Soc 2014;55(12):1739-1744

The purpose of this study is to suggest diagnosis indicators and checklist for urban regeneration projects by Korea Land & Housing Corporation(LH). There are already deprivation indices in the Urban Regeneration Act but not any additional guidelines in the practical aspect. In order to use the diagnosis indicators, the central government should supply more specific checklist to the actors in the regeneration field. The key actor of many stakeholders is LH as an operator and implementer in the regeneration projects. So far, LH has developed housing and cities and there haven't been any obvious changes to realize public benefit in the deteriorated area. From now on, It has to plan, implement, and manage a lot of regeneration projects entirely. Therefore, It is necessary to develope and apply the diagnosis indicators and checklist based on projects. This paper came up with the 6 factors related with LH business field : housing, urban infrastructure, public service, private service, environment, and smart city. For these, 32 diagnosis indicators and 72 checklists were selected that can include both physical and qualitative indicators. These can be used not only for the selection of regeneration projects but also for the process monitoring such as planning and implementation.

Purpose: To investigate the clinical features and prevention of ocular injuries associated with the mistaken use of superglue as eyedrops. Methods: Medical records of 13 patients with ocular superglue injury who visited our hospital from January 1, 2002 to December 31, 2004 were analyzed. The clinical features of ocular superglue injury and causes of using superglue instead of eyedrops for each patient were analyzed. Results: The present study involved 15 eyes of 13 patients, including seven men (53.8%) and six women (46.2%), ranging from 6 to 72 years of age, with a mean age of 38.4 years. Ocular superglue injuries were corneal abrasion in all patients. The bonding of eyelids (eight cases, 61.5%) and eyelashes (two cases, 15.4%) were identified. Ocular injuries were treated conservatively and resolved without complications. The major cause of mistaken use of superglue was similarly packaged eye drops (11 cases, 84.6%). Other causes included poor eyesight (one case) and unsupervised children (one case). Conclusions: The availability of eyedrops in various ocular diseases has recently increased, and superglue is found in many households, wherefore incidence of ocular superglue injuries can increase. Therefore, modifying the design of superglue bottles and providing proper education for patients to prevent ocular superglue injury is important. J Korean Ophthalmol Soc 2010;51(10):1398-1402

코경유 눈물주머니코안연결술 전 통상적인 이비인후과 의뢰의 임상적 효용성

목적: EN-DCR (endonasal dacryocystorhinostomy) 환자의 통상적인 술 전 이비인후과 의뢰가 가지는 효용성에 대해 알아보았다. 대상과 방법: EN-DCR 환자 178명 237안을 대상으로 전향적 연구를 하였다. 안과의사가 코 내시경으로 코 안 이상유무를 먼저 확인하고 심한 이상이 발견된 환자는 이비인후과에 의뢰하였다. 코 내시경 검사상 이상이 없는 환자를 A군, 코 안 이상으로 이비인후과 진료를 보았으나 수술에 큰 문제가 없다고 판단되어 EN-DCR만 시행한 환자를 B군, 이비인후과 의뢰 후 EN-DCR과 함께 부가적인 이비인후과 치료를 시행한 환자를 C군으로 분류하여 각 군의 빈도 및 수술성공률을 분석하였다.결과: 전체 178명의 환자 중 A군 156명, B군 12명, C군 10명이었고 심한 코 안의 이상으로 이비인후과 진료가 필요했던 환자는 총22명(12.3%)이었으며 군간 수술성공률은 통계적으로 차이가 없었다.결론: EN-DCR 전 통상적인 이비인후과 의뢰의 필요성은 그리 크지 않을 것으로 생각하며 술 전 안과의사의 검사 후 필요한 환자의 경우에만 이비인후과 진료를 의뢰한다면 환자의 시간적, 경제적 부담을 줄일 수 있을 것이다.

Urban railway system that leads the urban public transportation enables the passengers to use the subway system safely and conveniently by indicating the destination of, status of approach of and other information on train through Train Destination Equipment(TDE), which is one of the important passenger services. The existing system is composed of Host Station Equipment(HSE) and operator panel that receives necessary input on train information from Total Traffic Control System(TTC), Local Station Equipment(LSE) that controls Train Destination Indicator(TDI) installed at each station, and Train Destination Indicator that ultimately displays train information to the passengers using the train system. This study aims to realize stabilized and reliable announcement system for destination of train by considering processing procedure and method of expression of inputted information of the existing system of notification of announcement of destination of train that can be applied in the RFID, which is the base technology of USN for which service expansion is easy, and to realize system that considers interface with USN and expandability with other facilities in the future.
