Purpose: To evaluate the findings of carotid ultrasonography performed on patients with retinal vascular disease and to determine the risk of cardiovascular disease and association of retinal vascular disease and cardiovascular disease. Methods: From December 2009 to May 2012, patients diagnosed with central retinal artery occlusion (CRAO, n = 18), central retinal vein occlusion (CRVO, n = 23), and branch retinal vein occlusion (BRVO, n = 68) underwent carotid ultrasonography. We evaluated the intima-media thickness (IMT) of the common carotid artery (CCA) and the internal carotid artery (ICA), stenosis and the number of plaques, and then compared these results with those of a healthy control group (n = 221). Results: The mean CCA-IMT and ICA-IMT were significantly higher in the CRAO and BRVO groups compared with the control group. On the contralateral side, CCA-IMT was increased in the CRAO, BRVO, and CRVO groups and ICA-IMT was increased in the CRAO and BRVO groups compared with the control group. Contralateral CCA stenosis was higher in the CRVO group (9.1%) and ipsilateral ICA stenosis in CRAO group (21.7%) was significantly higher than that of the control group. Plaque was observed better in all groups compared with the control group. The proportion of patients risk for cardiovascular disease, i.e. those who had IMT thickenesses more than 1.0 mm, was higher in the CRAO and BRVO groups compared with the control group. Conclusions: The carotid ultrasound findings of patients with retinal vascular diseases showed increased IMT and plaque. The group of patient at risk for cardiovascular disease, which was defined with carotid artery IMT, was higher in patients with retinal vascular disease. Therefore, in patients with retinal vascular disease, carotid artery ultrasonography and the overall management and treatment of cardiovascular disease are necessary.

근대 이행기의 서구 과학기술 수용을 통해서 나타난 『덕혜입문』의 기독교적 이해

서상진(Seo, Sang-Jin) 동서신학연구소 2024 동서신학 Vol.8 No.1

『덕혜입문』은 런던선교회에서 중국으로 파송된 그리피스 존이 션즈싱(沈子星, 1825-1887)의 도움을 받아 1879년에 한문으로 초판을 출간한 이후, 약 50년 동안 일곱 차례(1882, 1887, 1890, 1897, 1907, 1908, 1909)에 걸쳐 출간되었다. 『덕혜입문』이 일곱 번에 걸쳐 지속적인 출판한 것은 독자들에게 널리 보급되었다는 것을 증명할 뿐 아니라 그 가치가 인정되었다고 할 수 있다. 『덕혜입문』은 1879년 우창에서 시행된 과거 시험을 응시하러 온 수험생들에게 전도하기 위해 배포된 도서이다. 화중 선교의 아버지(華中宣敎之父)라고 불리는 『덕혜입문』의 저자인 그리피스 존은 1876년 한커우서회(Hankow Tract Society)를 창립하여, 기독교 문서 사역에 집중했다. 그리피스 존은 한커우서회를 중심으로 많은 서적을 출간하여, 문서 선교에 큰 업적을 남겼는데, 그 저술 중 하나가 『덕혜입문』이다. 『덕혜입문』은 언더우드 선교사에 의해 번역되었고, 후에 게일 선교사에 의해 수정하여 개정판이 출간되었다. 『덕혜입문』은 중국 식자층을 전도하고자 하는 의도를 가지고 저술되었고, 당시 유학자들의 관심이 많았던 유교 경전과 심성론을 인용하여 사용하였고, 잘못된 부분을 냉철하게 지적하기도 했다. 또한 전도용으로 제작되었지만, 서구 과학기술과 서양 철학까지 소개하여, 중국 지식인들에게 기독교가 보편적 진리임을 말하고자 했다. 『덕혜입문』은 초기 한국교회에도 소개가 되어 1세대 교회 지도자들이 회심하기도 했다. 특히 개신교 7명의 목사 중 한 명인 서상륜(徐相崙, 1848-1926)의 동생 서경조(徐景祚, 1852-1938) 목사는 존 로스(John Ross, 1842-1915) 선교사에 의해 『덕혜입문』이 황해도 송천리(松川里, 우리말로 ‘솔내’라고 부르는 데, 여기서 ‘소래’란 이름이 유래했다)에 도착했을 때, 이 책을 읽고 회심한 것으로 전해진다. 『덕혜입문』은 초기 한국교회에 많은 영향을 주었다. “The Gate of Virtue and Wisdom” was first published in Classical Chinese in 1879 with the help of Shen Zixing (1825-1887) by Griffith John, who was dispatched to China by the London Missionary Society. Over the next 50 years, it was published seven times (1882, 1887, 1890, 1897, 1907, 1908, and 1909). The continuous publication of “The Gate of Virtue and Wisdom” not only proves its widespread dissemination among readers but also attests to its recognized value.“The Gate of Virtue and Wisdom” was distributed to candidates who came to take the imperial examinations held in Wuchang in 1879 for evangelistic purposes. Griffith John, the author of “The Gate of Virtue and Wisdom” known as the Father of Central China Mission, founded the Hankow Tract Society in 1876 and focused on Christian literature ministry. He made significant achievements in literature-based evangelism by publishing numerous books through the Hankow Tract Society, one of which was “The Gate of Virtue and Wisdom” “The Gate of Virtue and Wisdom” was translated by missionary Underwood and later revised and reissued by missionary Gale. The book was written with the intention of evangelizing the educated class in China, using and critically addressing Confucian classics and theories of human nature, which were of great interest to scholars at the time. Although it was created for evangelistic purposes, it also introduced Western science and philosophy to demonstrate to Chinese intellectuals that Christianity is a universal truth. “The Gate of Virtue and Wisdom” was introduced to the early Korean church, leading to the conversion of first-generation church leaders. Notably, Reverend Seo Gyeong-jo (徐景祚, 1852-1938), the brother of one of the seven Protestant ministers, Seo Sang-ryun (徐相崙, 1848-1926), converted after reading “The Gate of Virtue and Wisdom” when it arrived in Songcheon-ri (松川里, called ‘Solnae’ in Korean, from which the name ‘Sorae’ is derived) in Hwanghae Province, through missionary John Ross (1842-1915). “The Gate of Virtue and Wisdom” had a significant impact on the early Korean church.

Purpose: To compare the surgical outcomes of 23-gauge transconjunctival sutureless vitrectomy (TSV) with silicone oil tamponade versus 20-gauge PPV with sclera buckling (SB) and SF6 gas tamponade for the repair of rhegmatogenous retinal detachment (RRD) with inferior breaks. In addition, silicone oil tamponade was evaluated as an alternative option for patients with inferior RRD. Methods: Two different types of surgery were performed on two groups of patients with inferior RRD: 23-gauge TSV with silicone oil tamponade (group 1) and 20-gauge PPV with SB and SF6 gas tamponade (group 2). The preoperative clinical features, anatomical success rate, complications, functional outcomes (visual acuity, VA, intraocular pressure, IOP), and surgical time were retrospectively evaluated. Results: The primary surgical success rates were 94% and 78% in groups 1 and 2, respectively. The final success rate was 100% in both groups. Therefore, in terms of success rate, there was no difference between the two groups. No statistically significant difference in IOP change or complication rate was observed between the two groups. VA change was significantly better and surgical time was shorter in group 1. Conclusions: No statistically significant difference of anatomical success rate or complication rate between 23-gauge TSV with silicone oil tamponade and 20-gauge PPV with SB and SF6 gas tamponade was found for inferior RRD. However, surgical time was shorter in group 1. A 23-gauge TSV with silicone oil tamponade could be an alternative to 20-gauge PPV with SB and SF6 gas tamponade for patients with inferior RRD, especially patients who cannot maintain a prone posture.

Purpose: To determine the influence of morphologic classification based on optical coherence tomography (OCT) on epiretinal membrane (ERM) surgery outcomes. Methods: We retrospectively reviewed the medical records of 77 eyes with ERM treated by vitrectomy with ERM peeling. By using OCT, the preoperative ERM was classified into four types: diffuse (DIF), cystoids macular edema (CME), pseudolamellar hole (PLH), and vitreomacular traction (VMT). The postoperative changes of central macular thickness (CMT) and best-corrected visual acuity (BCVA) were compared. Results: Approximately six months postoperatively, the DIF type had the best BCVA for both idiopathic and secondary ERM, followed by the PLH, CME, and VMT types. On the other hand, regarding the mean BCVA improvement, the VMT type was the best, followed by the DIF, PLH, and CME types. When comparing the difference in BCVA improvement by each type, idiopathic ERM showed a clearer distinction when the inner segment/outer segment (IS/OS) junction was not disrupted. Conclusions: BCVA improvement was significantly different depending on the morphologic classification of ERM by using OCT. Especially in cases of ERM with an intact IS/OS junction, the morphologic classification can help predict surgical outcomes. J Korean Ophthalmol

Purpose: To report a case of congenital idiopathic microcoria corrected with pupilloplasty and amblyopia treatment. Case summary: A 4-year-old girl was referred for pupillary abnormality of the left eye. Her mother experienced no problems during gestation, and the patient was born at full term. On initial examination, visual acuity was 20/25 in the right eye and counting finger at 50 cm in the left eye. Slit lamp examination revealed that the left pupil was displaced superonasally. A band of fibrous tissue extended across the left pupil and there was no red reflex. There was very slight reaction to mydriatics. Using 23-gauge vitrectomy scissors, a pupilloplasty was performed, and the synechiae are removed. Postoperatively, the pupillary light reflex was brisk, and occlusion therapy was initiated. After 3 months, the visual acuity of the left eye improved to 20/30. Conclusions: In our case, although microcoria was diagnosed at a relatively old age, the patient’s clinical features were consistent with congenital idiopathic microcoria. Therefore, we diagnosed the patient with gradually progressed congenital idiopathic microcoria. In the case of typical congenital idiopathic microcoria, the red-reflex is absent at birth because of the small pupil. However, as in our case, it is possible that the pupil can contract gradually due to movement of the fibrous strand. The point must be considered in such patients.

현재 전자우편은 정보통신 사회의 중요한 의사소통 수단이 되고 있으나, 스팸 메일의 증가로 인해 각종 사회 문제를 발생시키고 있다. 스팸 차단을 위해 관련 기관 및 기업이 다양한 형태의 스팸 차단 기술을 개발하고 있으나, 다양한 스팸 유형에 따른 대응이 각각 이루어져야 하므로 많은 처리 비용과 시스템의 복잡도가 가중되고 있다. 그리고 스팸 차단 기술 적용 시, 스팸 방지 필터의 적용 순서에 따라 차단 오인율(False-Positive Error)이 달라져 이용 신뢰도에 큰 영향을 끼친다. 본 논문에서는 스팸 차단 필터의 이용 신뢰도를 향상시키기 위해, Privacy 정보 기반의 False-Positive 메일 복구 기법을 제안 및 구현하였다. 구현된 프로토 타입을 통해 False-Positive 메일 복구 과정을 검증하고, 처리 결과를 분석 및 요약한다. While E-mail has become an important way of communications in IT societies, it creates various social problems due to increase of spam mails. Even though many organizations and corperations have been doing researches to develop spam mail blocking technologies, more cost and system complexities are required because of varieties of blocking technologies. In case of adopting spam blocking technologies, system reliability largely relies on the False-positive error rate with the order of employing spam blocking filters. In this paper, a False-positive mail recovery technique based on privacy information is proposed and implemented in order to improve the reliability of spam locking filters. Through the implemented prototype, recovery procedure for False-positive mails is verified and the results are summarized and analyzed.
