Purpose: The goals of the present study were to measure a ratio of accommodative-convergence to accommodation (AC/A ratio) in child patients with refractive accommodative esotropia (RAET) and to compare it to the ratio in normal children. Methods: Patient age, gender, and refractive errors were examined. The deviation angles were measured at near and distance using a prism cover test and were followed by the measurement of the interpupillary distance. The AC/A ratio was calculated using a heterophoria and a gradient method. Results: The present study consisted of 59 patients, 38 patients with RAET and 21 normal children. The mean ages were 9.6 years in patients with RAET and 9.0 years in the normal children. The refractive errors in spherical equivalent were shown to be 4.6D in the right eye and 4.5D in the left eye in patients with RAET and -0.4D and -0.5D in the normal children. The mean values of the AC/A ratio using a gradient method were 1.8 in patients with RAET and 2.2 in the normal children(p=0.44). According to the heterophoria method, the AC/A ratio was 6.2 in patients with RAET and was 5.4 in the normal children(p=0.04). Conclusions: The AC/A ratio of child patients with RAET was higher than that of normal children when using a heterophoria method. However, there was no difference in the AC/A ratio between the normal children and RAET child patients when using gradient method.

Purpose: To report a case of fusarium keratitis treated with only moxifloxacin 0.5% ophthalmic solution (Vigamox?, Alcon Laboratories, Inc., Ft Worth, TX, USA). Case summary: A 37- year- old healthy male patient experienced a right eye injury due to grain 7 days prior to presentation at our hospital with visual disturbance and ocular pain. A 2.7 × 4.3 mm sized corneal epithelial defect with irregular featherlike midstromal infiltration was observed, and slit lamp examination revealed a dry, rough texture. Thus a smear and culture were performed. Moxifloxacin 0.5% ophthalmic solution (Vigamox?) and lubricant were applied for treatment. Three days after using the eye solution, all clinical features improved. Seven days later, Fusarium species was identified in culture. Conclusions: As standard treatment for Fusarium, the authors of the present study used an antifungal agent. Although hyphae were detected in culture, the use of only moxifloxacin 0.5% ophthalmic solution (Vigamox?) result in a satisfactory result and improvement in clinical features.

Purpose: The present study evaluated the developmental characteristics and causes of nasal retinopathy of prematurity (ROP). Methods: A total of 111 eyes from 56 ROP-affected infants who had been treated with laser photocoagulation by retina specialists at the nasal site were examined. The gestational age at birth and diagnosis, location of the lesion, time, and number of laser photocoagulation therapies for nasal and temporal ROP were analyzed. Results: Thirty-three cases (29.7%) were diagnosed with nasal ROP. The mean gestational age at birth was 28.43 weeks for nasal ROP, and 29.44 weeks for temporal ROP (p = 0.022). Additionally, the average gestational age of infants who received laser photocoagulation was 36.61 weeks for nasal ROP, and 39.71 weeks for temporal ROP (p = 0.001). The average number of ROP laser photocoagulation trials was 2936.03 for nasal ROP, and 1611.83 for temporal ROP (p = 0.0001). No case was observed with a wider avascular area in the nasal retina than in the temporal retina. Additionally, compared to the temporal ROP, the nasal ROP showed significant difference in progression rates, 33.3% in the nasal group and 8.97% in the temporal group (p = 0.001). Conclusions: Nasal ROP was due to the ROP lesions developing earlier in the nasal than the temporal retina, although not due to any atypically wider nasal avascular area. In these cases, nasal ROP showed more disease progression compared to temporal ROP. J Korean Ophthalmol Soc 2011;52(12):1485-1489

W3C에서 XML을 인터넷 환경에서 정보교환의 문서표준으로 채택함에 따라 XML 사용자가 증가하고 있다. 인터넷 환경에서는 다양한 하드웨어, 소프트웨어 플랫폼이 공존하고 있고 네트워크의 연결이 제한적이다. 한편 다양한 종류의 정보가 생산되고 또한 정보의 내용이 수시로 변화하는 관광산업의 특성에 맞추어 적절한 시간에 사용자의 의도에 맞게 정보를 가공하여 신뢰성 있는 수단으로 적시에 고객에게 관광정보를 제공할 수 있는 시스템이 필요하다. 본 연구는 이동 컴퓨팅 플랫폼과 분산되고 이질적인 환경 하에서 안정적이고 신뢰성 있게 정보를 전송할 수 있는 관광정보 시스템에 관한 논문이다. The internet is comprised of various users with diverse hardware and software platforms. This paper presents a tourism information system which enables the stable and reliable transmission of information over the dispersed, heterogeneous, and/or mobile platforms. The proposed system assumes XML as the basic document format since it has been accepted by W3C as the standard for information exchange on the internet This paper exploits the characteristics of JAVA and XML as they provide software applications independent of the platforms. The proposed system also deploys Aglet, a mobile agent developed by IBM, to ensure a dynamic and flexible performance of the system over the internet. The system provides the user oriented search and retrieval of tourism information, and also enables the reservation of various services and facilities with mobile devices.
