유형곤,권강훈,김영길,Yoo, Hyeong-Gon,Kwon, Kang-Hoon,Kim, Young-Kil 한국정보통신학회 2013 한국정보통신학회논문지 Vol.17 No.12

일반적으로 함정은 표적을 탐지하고 추적하는 기능을 하는 다양한 장비를 보유하고 있으며 각 장비들 간의 정보교류를 통해 보다 정확하고 신속하게 대상 표적을 추적하고 있다. 이런 장비들은 대체로 유사한 표적탐색영역(FOV)을 보유하지만 일부는 해당 장비의 오차범위(Resolution) 한계로 인해 장비간의 차이가 발생하기도 한다. 본 논문에서는 전자광학추적장비(Electro Optic Tracking System)와 레이더 시스템 간의 표적탐색영역(FOV) 차이를 보상하기 위해 사용된 전자광학추적장비 표적탐색 방식을 랜덤한 표적정보를 기준으로 다양한 방법을 통해 탐색시간을 단축하고, 자동으로 표적을 탐지/추적할 수 있는 방법에 대해 연구하였다. This is an example we generally have a variety of equipment that can detect and track the targets and track them quickly and accurately through the information exchange among each piece of equipment. These equipment have similar detection areas (FOV), but some are different due to the limit of the resolution of the equipment. In this paper, we studied the method of reducing detection time and tracking the targets automatically.

전력소요검증 시 과학기술분야 정부출연연구기관 보유기술의 활용성 평가 방법론

유형곤 광운대학교 방위사업연구소 2018 선진국방연구 Vol.1 No.2

Recently, in order to efficiently utilize the national R&D budget and expand transparency in the development of weapon system, it is expanding the need fr using technologies owned by civil government-funded research institutes. This paper aims to introduce the concept of utilization of technology in the civil government-funded research institutes, the quantitative evaluation methodology and the facilitating policies in the process of requirements validation of weapon system. 최근 국가연구개발 예산을 효율적으로 활용하고, 민 • 군간 기술협력 활성화를 위하여 국가과학기술연구회 소관 정출연 등 민간연구기관이 보유하고 있는 우수 기술을 무기체계에 활용해야 한다(Spin-On)는 공감대가 확산되고 있다. 이에 따라 본 논문은 각각 기술제공자 요인, 기술특성 요인, 상호 요인 둥 측면에서 정출연 보유기술의 활용성 수준에 영향을 미치는 4가지 요소를 도출하고, AHP 설문조사를 통해 본 4가지 요소별 상대적인 가중치를 산출하여 무기체계 개발착수 이전 시점인 전력소요검증 단계부터 정출연이 보유하고 있는 기술의 무기체계 활용성이 어느 정도인지를 정량적으로 평가할 수 있는 방법론을 제시하였다. 그리고, 향후 전력소요검증 시점에서 민간기술 활용성 평가 제도를 내실화할 수 있는 정책적 •제도적 개선사항을 제안하였다. 본 논문에서 제시한 민간기술 활용성 평가 방법론은 향후 관련 기관 간 활용성(Spin-On) 관점의 민군기술협력을 촉진할 수 있는 제도적 · 정책적 발전방안을 수립하는데 유용한 근거로 활용될 수 있을 것으로 기대한다.

Current Smoking Is Associated with a Poor Visual Acuity Improvement after Intravitreal Ranibizumab Therapy in Patients with Exudative Age-Related Macular Degeneration

유형곤,송수정 대한의학회 2013 Journal of Korean medical science Vol.28 No.5

In this study, the risk factors that may influence visual improvement after intravitreal ranibizumab (IVR) treatment for exudative age-related macular degeneration (AMD) were examined. From 2008 to 2012, 420 patients (448 eyes) with exudative AMD were prospectively registered at Seoul National University Hospital. From this group of patients,125 eyes were included in this study. All patients were treated with 3 consecutive IVR injections. The visual acuity (VA) was evaluated at baseline and 1 month after the third ranibizumab injection. To evaluate the risk factors associated with VA improvement after IVR, patient demographic data and systemic risk factors were analyzed. Patients were divided into a poor VA improvement group and a good VA improvement group, with reference to the median visual improvement in all eyes. Among 125 eyes, 66 eyes (52.8%)were included in the responder group and 59 eyes (47.2%) in the non-responder group. The median VA improvement after 3 monthly ranibizumab injections was -0.05 logMAR. Multivariate analyses revealed that current smoking (adjusted OR, 7.540; 95% CI, 1.732-32.823) was independently associated with poor VA improvement after IVR treatment for exudative AMD. In conclusion, cigarette smoking is an independent risk factor for lower VA gains with IVR treatment for exudative AMD.

방산업계의 국방기술혁신역량 평가체계 구축 연구

유형곤 한국방위산업학회 2015 韓國防衛産業學會誌 Vol.22 No.1

최근 정부는 업체주도 연구개발 비중을 확대하는 등 방산업계의 국방기술혁신역량을 강화하기 위해 적극적으로 노력하고 있다. 하지만, 아직까지 국내 방산업계의 국방기술혁신역량 평가체계가 제대로 마련되어 있지 않기 때문에 현재 어느 정도 수준인지 파악하기 곤란한 실정이다. 본 고는 포터의 국가경쟁력 모델을 기반으로 (1)방산업계의 연구개발 기반 및 활동수준, (2)정부의 기술혁신 노력 수준, (3)동반성장 수준 및 방위산업 생태계 건강성, (4)타 부처 및 국내·외 유관기관과의 협력 수준 등의 분야에서 국내 방산업계의 국방기술혁신역량을 평가할 수 있는 지표 항목과 평가체계를 제시하였다. It is well known that the technology innovation capability is crucial to raise international competitiveness of industry in the world market. Therefore, our government also makes an effort to improve technology innovation capability of defense industry and increase defense R&D budget belongs to defense company. However, so far, there is no systematic index which represents technology innovation capability of defense industry. As a result, it is difficult for our government to assess the level of technology innovation capability and the outcome by the investment of R&D budget. This study aims to establish the evaluation methodology measuring the technology innovation capability of defense industry based on M. Porter’s national competitiveness model. The evaluation methodology contains the following 4 areas: the defense R&D basis and activity in the defense industry, our government’s efforts to increase technology innovation capability, win-win growth and ecosystem of defense industry, cooperation system between our defense industry and national/international R&D organization.

나이관련황반변성에서 영양보충제의 역할

유형곤,마대중 대한의사협회 2016 대한의사협회지 Vol.59 No.12

Age-related macular degeneration (AMD) is the leading cause of visual impairment and blindness in the elderly in developed countries but therapeutic options are limited. Many observational studies have shown that a high dietary intake of antioxidants, fish oil, and carotenoids is associated with a lower risk of prevalent and incident AMD. The Age-Related Eye Disease Study 1 demonstrated that routine supplementation with a certain formulation of vitamins C, E, β-carotene, and zinc with copper reduces the risk of worsening AMD and severe vision loss by 25% over a 6-year period in patients with intermediate or advanced AMD in 1 eye or intermediate AMD in both eyes. The recent Age- Related Eye Disease Study 2 demonstrated that a certain combination of lutein and zeaxanthin is a safe and effective alternative to β-carotene, which is known to be associated with lung cancer in smokers. The aim of this review focuses on the role of supplements in the treatment and prevention of AMD and sums up the recent findings about the micronutrients most frequently used for AMD.

Purpose: To investigate the effects of repeated photodynamic therapy (PDT) for subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD) in Korean patients. Methods: Clinical data of patients who were treated with repeated (3 times or more) PDT for subfoveal choroidal neovascularization secondary to AMD and followed up for more than 6 months were collected from 17 hospitals around the country. Visual outcomes at 12 and 24 months, follow-up were compared between subtypes of choroidal neovascularization. The factors related to final visual prognosis and PDT-related adverse effects were evaluated. Results: 244 patients (244 eyes) were recruited (male: 60%, age: 67.7±9.1 years). The portion of patients with predominantly classic, minimally classic, and occult without classic choroidal neovascularization was 57%, 13%, and 24%, respectively and that of patients with visual improvements or less than moderate visual loss at 24 months follow-up were 28%, 38%, 30% and 47%, 56%, and 65%, respectively. Baseline visual acuity and age were significantly related to the final visual prognosis (p<0.05). PDT-related adverse events developed in 15 (6.1%) patients, but most were mild and transient. Conclusions: Repeated PDT for subfoveal choroidal neovascularization secondary to AMD has effects comparable to those of previous prospective, controlled trials without any significant safety concerns in Korea.
