Purpose: To investigate the efficacy and detection rate of disease in the customized eye examination program. Methods: We reviewed the medical charts of 122 patients who have conducted the customized eye examination program from January 2018 to January 2019 in Kim’s Eye Hospital retrospectively. The customized eye examination program consisted of visual acuity test, intraocular pressure measurement, color vision test, slit-lamp examination, visual field tests, fundus photography, spectral domain optical coherence tomography (Cirrus HD-OCT, Zeiss), Optical Quality Analysis System (OQAS, Visiometrics, Terrassa, Spain), and dry eye test (LipiView II TearScience, Morrisville, NC, USA). The rate of newly diagnosed diseases and vision-threatening disorders including glaucoma and retinal disorders were calculated. Results: A total of 122 patients (46 males and 76 females, mean age; 47.8 ± 14.0 years old, from 22 to 85 years) were included. Nine patients (14 eyes) had a poor vision of less than 0.8. Newly detected diseases were found in 17 patients (13.9%), and among them, 10 glaucoma (8.2%) and retinal disorders (5.7%) were included. When it comes to glaucoma, 7 patients were diagnosed with definite glaucoma with visual field loss, and 3 patients had preperimetric glaucoma. Retinal disorders were composed of 5 epiretinal membranes, 1 diabetic retinopathy, and 1 central serous chorioretinopathy. Conclusions: Various diseases were identified by the customized eye examination program, and vision-threatening diseases such as glaucoma and retinal disorders were found. Therefore, a regular eye examination is needed to detect the serious ocular diseases in the early stage.

김재익,황국웅,정현욱,여창환 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

위성영상은 도시의 물리적 확산 및 변화를 예측하는데 많이 활용되고 있다. 그러나 이 방법은 도시화된 지역이 어느 정도의 강도로 개발되었는지를 파악할 수 있는 밀도분석에는 적절치 못하다. 이는 위성영상이 미시적 공간단위로 토지이용 현황을 분석하는 반면 통계자료는 거시적 공간단위로 구축되어 있어 통계자료를 미시적인 공간단위에 적용하는데 어려웠기 때문이다. 본 연구는 위성영상자료와 통계청의 기초단위구라는 미시적 구역통계자료를 활용하여 도시성장분석상 이들 자료를 통합하여 활용하는 것이 유용함을 입증하고자 하였다. 연구대상지역은 대구광역시로 하였으며, 분석자료로 1985년과 2000년의 위성영상 Landsat TM틀 와 구역통계자료로 기초단위구를 이용하였다. 분석결과 위성영상자료는 도시의 확산 그리고 기초단위구는 밀도 분석이 용이하여 도시성장에 따른 확산과 밀도변화를 동시에 파악할 수 있었다. Nowadays, a satellite image is widely utilized in identifying and predicting urban spatial growth. It provides essential informations on horizontal expansion of urbanized areas. However, its usefulness becomes very limited in analyzing density of urban development. On the contrary, zonal data, typically census data, provides various density information such as population, number of houses, floor information within a given zone. The problem of the zonal data in analyzing urban growth is that the size of the zone is too big. The minimum administration unit, Dong, is too big to match the satellite images. This study tries to derive synergy effects by matching the merits of the two information sources-- image data and zonal data. For this purpose, basic statistical unit (census block size) is utilized as a zonal unit. By comparing the image and zonal data of 1985 and 2000 of Daegu metropolitan area, this study concludes that urban growth pattern is better explained when the two types of data are properly used.

김선주,정명아,정현주,김윤정,맹국영 대한감염학회 1998 감염 Vol.30 No.4

배 경 : ASO 검사는 S. pyogenes 감염과 류마티스열이나 급성 사구체신염 등 후유증을 진단하는데 매우 유용하다. ASO 정상치는 연령에 따라 달라지는 것으로 알려져 있으므로, 단회의 ASO 결과를 올바로 해석하기 위해서는 같은 지역의 동일한 연령의 정상치를 알고 있어야 한다. 방 법 : 저자들은 진주지역 학동기전 아동 (162명), 초등학생 (436명)과 성인 (231명) 세 군에서 ASO 정상치와 분포를 살펴보았다. 연쇄구균 감염 증상이나 징후가 없는 진주 지역 주민들을 대상으로 혈청내 ASO치를 자동화학분석기 (Cobas Mira, Roche)와 비탁기 (Behring Nephelometer 100 Analyzer)를 이용하여 정량 분석하였다. 결 과 : 학동기전 아동, 초등학생 및 성인에서의 평균 ASO치는 각각 71 IU/mL (표준편차 107), 285 IU/mL (표준편차 246) 및 80 IU/mL (표준편차 64) 이었고, 정상상한치는 각각 131 IU/mL, 433 IU/mL, 136 IU/mL 이었다. 결 론 : ASO 정상치 및 분포는 각 연령군에 따라 크게 다르므로, ASO 정상치는 연령에 따라 다르게 설정되어야 할 것이다. A군 연쇄구균 감염은 학동기전 아동이나 성인에서는 매우 드문 반면, 초등학생에서는 빈번함을 알 수 있었다. Background : Antistreptolysin O (ASO) is very useful as an indicator of recent streptococcal infection and its sequelae, such as rheumatic fever and acute glomerulonephritis. Becuase the upper limit of normal (ULN) value of ASO varies according to age, the ULN value of ASO in an area should be evaluated to accurately interpret single ASO levels of patients. Methods : The ULN value and distribution of ASO concentrations were investigated in three age groups of preschool children (N=162), elementary school children (N=436), and adults (N=231) in Chinju. ASO concentrations were measured quantitatively by autoanalyzer or nephelometer from sera of healthy population in Chinju who had no symptoms or signs of streptococcal infections. Results : The mean (±SD) ASO concentrations were 71 (±107) IU/mL, 285 (±246)IU/mL, and the UNL value of ASO concentratios were 131IU/mL, 433IU/mL, and 136 IU/mL in each group of preschool children, elementary school children, and adults, respectively. Conclusion : The distributio and ULN value of ASO concentrations varied according to age group. The ULN value of ASO concentrations should be set differently according to the patient's age. Group A streptococcal infections might be quite common in elementary school children, while very rare in preschool children or adults.

김성국,신홍인,박희경,장현중,김영미,김진수 大韓顎顔面成形再建外科學會 1996 Maxillofacial Plastic Reconstructive Surgery Vol.18 No.1

Ameloblastomas are benign epithelial neoplasm of the jaw comprising approximately 1-3.3% of all odontogenic cysts and tumors. Although most are microscopically benign, they are generally considered to be locally aggressive and destructive, exhibiting a high rate of recurrence. Treatments of them contain the conservative treatments on unilocular types and radical treatments on multilocular types. Classifications based on the histologic features of ameloblastoma generally included the follicular, plexiform, acanthomatous, basal cell, uncystic types. However, recantly a new and unusual variant has been added by Eversole et. al in 1984, the histologic features of which are characterized by marked stromal desmoplastic proliferation. This is a case report of desmoplastic ameloblastoma in the anterior maxilla of 63 year-old female treated by block excision. THis provides a brief review of the literature because of the rarity and unusual radiographic-histologic features of desmoplastic ameloblastoma.

Authors evaluated the clinical validity of KVSS Test compared with CC-SIT (Cross-Cultural Smell Identification Test) in Korean. Materials and Methods: The subjects of this study were 25 normosmic volunteers who were divided into five groups according to age. Each group was 5 normosmic volunteers. And they consisted of 12 men and 13 women. KVSS Test and CC-SIT were used for the evaluation of olfactory function. Results: Our study showed the negative correlation between age and olfactory function test (CC-SIT score, KVSS Test I score and KVSS Test II score). Normosmia rate of KVSS Test was more higher than that of CC-SIT. Also KVSS Test had more familiar items for Koreans compared with that of CC-SIT. CC-SIT score and KVSS Test score showed showed the positive corrclation. And each test revealed high reliability in test-retest evaluation. Conclusion: The KVSS Test can be used as an olfactory function test for Koreans.

복합 산화법과 MEMS 기술을 이용한 RF용 두꺼운 산화막 에어 브리지 및 공면 전송선의 제조

김국진,박정용,이동인,이봉희,배영호,이종현,박세일 한국센서학회 2002 센서학회지 Vol.11 No.3

본 논문에서는 양극반응과 복합 산화법( H_2O/O_2 분위기에서 500℃, 1시간 열산화와 1050℃, 2분간 RTO(Rapid Thermal Oxidation) 공정)을 이용한 두꺼운 OPSL(Oxidized Porous Silicon Layer)을 형성하여 이를 마이크로머시닝 기술을 이용함으로써 10 ㎛두께의 OPS(Oxidized Porous Silicon) 에어 브리지를 제조하고, 그 위에 전송선로를 형성하여 그 RF 특성을 조사하였다. OPS 에어 브리지 위에 형성된 CPW(Coplanar Waveguide)의 손실이 OPSL 위에 형성된 전송선의 삽입손실보다 약 2 dB 정도 적은 것을 보여주었으며, 반사손실은 OPSL 위에 형성된 전송선의 반사손실보다 적으며 약 -20 dB를 넘지 않고 있다. 본 연구에서 개발한 산화된 다공질실리콘 멤브레인 및 에어 브리지 구조는 CMOS 공정 후에 사용 가능하며, 초고주파 회로 설계시 편리성과 유용성을 제시하고 있다. This paper proposes a 10 ㎛ thick oxide air-bridge structure which can be used as a substrate for RF circuits. The structure was fabricated by anodic reaction, complex oxidation and micromachining technology using TMAH etching. High quality films were obtained by combining low temperature thermal oxidation (500 ℃,1 hr at H_2O/O_2) and rapid thermal oxidation (RTO) process (1050 ℃, 2min). This structure is mechanically stable because of thick oxide layer up to 10 ㎛ and is expected to solve the problem of high dielectric loss of silicon substrate in RF region. The properties of the transmission line formed on the oxidized porous silicon (OPS) air-bridge were investigated and compared with those of the transmission line formed on the OPS layers. The insertion loss of coplanar waveguide (CPW) on OPS air-bridge was (about 2 dB) lower than that of CPW on OPS layers. Also, the return loss of CPW on OPS air-bridge was less than about - 20 dB at measured frequency region for 2.2 mm. Therefore, this technology is very promising for extending the use of CMOS circuitry to higher RF frequencies.
