Purpose: To evaluate the efficacy of tattooing with tissue marking dye for cosmetic repair of corneal opacity. Methods: Tattooing by the injection of tissue marking dye into the corneal stroma was performed in 67 eyes of 67 patients in whom there were no changes in visual acuity or size of corneal opacity for at least 5 years. Conjunctivalized corneal opacities and calcium deposits were removed before tattooing. All patients were followed up for a period of at least 3 months. Results: The most common causes of corneal opacity were trauma (56.6%) and infectious disease (19.4%). Combined ocular diseases included sensory exotropia (43.3%) and band keratopathy (31.3%). In this study, 98.5% of patients showed satisfactory results with cosmetic staining. Remaining opacity was observed in 1 eye (1.5%). Intraoperative complications occurred in 6 eyes (9.0%) and were resolved completely during surgery. Foreign body sensations (38.8%) and conjunctival injection (32.8%) disappeared within 2 months after surgery. Conclusions: Cosmetic repair by tattooing using tissue marking dye is an effective treatment for corneal opacity and is not associated with any significant complications.

무전해 도금에 의해 성장되어진 은 나노결정의 반사율 특성

김신우,Kim, Shin-Woo 한국결정성장학회 2013 韓國結晶成長學會誌 Vol.23 No.5

본 연구에서는 LCD 또는 LED를 이용한 디스플레이 장치의 BLU 반사판으로 사용할 목적으로 무전해도금에 의하여 플라스틱 기판위에 성장되어진 은 나노코팅의 반사율 특성을 조사하였다. 은 나노코팅의 미세구조는 아주 미세한 나노크기의 은 결정들로 이루어진 다결정 나노코팅인 것을 확인할 수 있었으며 코팅 층의 두께가 증가함에 따라 환원, 석출된 은 나노결정입자의 크기도 비례하여 증가되었다. 은 나노코팅의 두께가 증가함에 따라 가시광선 영역의 반사율이 감소하였으며 파장이 짧을수록 반사율의 감소가 더 심하였다. 나노코팅의 두께 증가에 따른 반사율의 감소는 환원 석출된 은나노결정의 크기와 밀접하게 관련된 것으로 은 결정입자가 클수록 요철의 정도가 심하여 반사율이 감소하는 것으로 생각되어진다. 그래서 가능한 미세한 은 나노결정을 환원, 석출시키고 코팅두께를 얇게 하는 것이 반사율 관점에서 바람직한 것으로 판단되어진다. In this study, the reflectivity characteristics of Ag nano-coating grown by electroless plating were investigated in order to use as the reflecting plate of BLU (Back Light Unit) in the LCD (Liquid Crystal Display) or LED (Light Emitting Diode) display equipment. The microstructure of Ag nano-coating was polycrystalline nano-structure that consisted of Ag nano-crystals to be reduced and precipitated, and the size of reduced nano-crystals increased as the thickness of nano-coating increased. The reflectivity of Ag nano-coating in the visible light decreased as the thickness of nano-coating increased and the reduction of reflectivity was more severe in the short wavelength region of visible light. The decrease of reflectivity was closely related to the size of Ag nano-crystal and was thought to be due to the larger surface roughness of larger nano-coating thickness. Therefore, the finer Ag nano-crystals and thinner nano-coating thickness could be favorable for the higher reflectivity of Ag nano-coating grown by electroless plating.

Purpose: To analyze the outcome of cataract surgery and to determine factors influencing the postoperative visual acuity in patients aged 85 years and older. Methods: The best corrected visual acuity before and 3 months after cataract surgery in patients aged 85 years and older was measured. Age, sex, diabetes mellitus, hypertension, astigmatism, corneal endothelial cell count, ocular comorbidity, and intraoperative complication were analyzed to determine which factors influence the postoperative visual acuity. Results: The postoperative visual acuity improved in 87% of patients, and a visual acuity of 20/40 or better was achieved in 56% of patients. Posterior capsular rupture and zonular dialysis were found as intraoperative complications in 16% of patients. Multiple regression analysis was used to determine which factors influence the postoperative visual acuity; age(p=0.009), ocular comorbidity (p=0.009), and intraoperative complication (p=0.010) were significantly associated with postoperative visual acuity. Conclusions: The postoperative visual acuity following cataract surgery in patients aged 85 years and older improved in 87% of patients, and old age, ocular comorbidity, and intraoperative complication were predictors of a poorer visual outcome.

A Brief Telephone Severity Scoring System and Therapeutic Living Centers Solved Acute Hospital-Bed Shortage during the COVID-19 Outbreak in Daegu, Korea

김신우,이경수,김건엽,Jung Jeung Lee,Jong-yeon Kim,Daegu Medical Association 대한의학회 2020 Journal of Korean medical science Vol.35 No.15

With the epidemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2, the number of infected patients was rapidly increasing in Daegu, Korea. With a maximum of 741 new patients per day in the city as of February 29, 2020, hospital-bed shortage was a great challenge to the local healthcare system. We developed and applied a remote brief severity scoring system, administered by telephone for assigning priority for hospitalization and arranging for facility isolation (“therapeutic living centers”) for the patients starting on February 29, 2020. Fifteen centers were operated for the 3,033 admissions to the COVID-19 therapeutic living centers. Only 81 cases (2.67%) were transferred to hospitals after facility isolation. We think that this brief severity scoring system for COVID-19 worked safely to solve the hospital-bed shortage. Telephone scoring of the severity of disease and therapeutic living centers could be very useful in overcoming the shortage of hospital-beds that occurs during outbreaks of infectious diseases.

패션분야 융합인재 육성을 위한 캡스톤 디자인 교육프로그램 학습 모형 개발 - NCS 패션분야 중심으로 -

김신우,김영인 한국의상디자인학회 2019 한국의상디자인학회지 Vol.21 No.4

In this paper, Capstone Design Education Program Learning Model was developed and recommended in order to foster convergent talents armed with practical competences and real cooperative capabilities. In this era of convergence and creativity, the fashion world needs human resources with cooperative skills and true professional abilities. A case analysis, an in-depth interview, and 1,2 test method were used for data acquisition and analysis. The summary of this study is described below. First, this program needs to complement the NCS fashion design learning module. Second, material changes to creativity and practical competencies - knowledge, skills, and attitudes - of the students are assessed after applying Capstone Design to the NCS fashion design learning model. Third, the process of converging fashion curriculum with IT and electronic technology, developing a fashion design learning program, and applying the Capstone Design was tested to prove the effectiveness of convergent fashion design education. Among the changes observed between the trial and control groups, it was confirmed that sub-factors of creative personality, i.e. self-assurance and openness, were increased along with knowledge, core competences including communication capability, and self-directed learning capability. The greatest improvement on the technological side was observed in IT literacy while ability to respond to changes was also increased. Besides, effects were demonstrated in behavioral factors such as initiative, spirit of challenge, experience, and openness. Lastly, the Capstone Design Education Program Learning Model was proposed in order to foster convergent talents in the fashion world.

지역사회획득 폐렴의 외래진료

김신우 대한내과학회 2011 대한내과학회지 Vol.81 No.5

지역사회획득 폐렴의 외래 치료는 국내에서 흔한 원인균인 S. pneumoniae에 대한 β-lactam 항생제와 macrolide 병용투여가 권장되고 있다. Macrolide 단독 투여는 국내 실정에서는 외국 가이드라인들과는 달리 macrolide 고도내성 S. pneumoniae로 인해 권장되지 않는다. β-lactam 항생제 단독투여와 β-lactam 항생제와 macrolide 병용투여의 비교 연구는 결정적 근거가 없으나 β-lactam 항생제 단독제제도 사용 가능할 것으로 가이드라인은 제시한다. 호흡기용 fluoroquinolone의 단독사용은 가능하나 결핵의 가능성이 있는 경우 1차 진료 시 사용하지 않는 것이 좋을 것으로 보이며 향후 내성 증가에 대한 관심이 필요하다. 흔한 원인균과 항생제 내성 등의 고려 외에 경험적 치료를 위해서는 기저질환과 연관된 원인균을 추가적으로 고려하는 것이 필요하다. 많은 지역사회획득 폐렴이 중증도가 높지 않은 경우 외래 치료가 가능하고 이에 대한 적절한 치료가 제시되어 있다. 이에 대한 근거중심의학적 권유(국내 가이드라인 및 외국 가이드라인 등)가 나와 있으며 가이드라인을 따를 때 좋은 예후를 보임은 잘 증명되어 있다. 그러므로 이에 대한 적극적인 적용이 확산되는 것이 필요하다.
