Purpose: The purpose of this study is to confirm the effect of antiplatelet drugs in diabetic peripheral vasculopathy in diabetic foot patients. Materials and Methods: We designed a retrospective study in diabetic foot patients with diabetic peripheral vasculopathy. From October 2007 to December 2013, 278 cases in 139 patients who took antiplatelet drugs over at least a six-month period were included in this study. We categorized these patients according to the type of drug used. The efficacy of antiplatelet drugs was evaluated using anklebrachial index (ABI) and pulse wave velocity (PWV). Results: Only the aspirin group showed a statistically significant increase of ABI after antiplatelet therapy ($1.10{\pm}0.12$ to $1.12{\pm}0.11$). In addition, only the cilostazol group showed a statistically significant decrease of PWV after antiplatelet therapy ($1,701.20{\pm}396.56$ to $1,627.42{\pm}324.98$). Conclusion: Aspirin and cilostazol may be used in treatment of diabetic peripheral vasculopathy, whereas dual antiplatelet therapy with aspirin and clopidogrel has no specific benefits in diabetic peripheral vasculopathy.

일본 산닌-쓰시마 해양에 존재하는 퇴적분지의 분포와 특성

박세진,Park Se-Jin 한국석유지질학회 2004 한국석유지질학회지 Vol.10 No.1

본 자료는 지난 1979년 일본석유기술협회지(Journal of the Japanese Association of Petroleum Technologists, vol. 44)에 게재된 보고서의 일부로, 신서일본석유개발(주)소속의 Akira Minami가 발표한 논문(일본명 산음-마충 퇴적분지의 분포와 성격)을 한역하였다. 영문이나 우리 말로 바꾸기 어려운 경우가 많아서 확실하지 않은 것은 원전대로 표기하였다. This article discusses stratigraphy and geological history of continental shelf area covering of offshore San-in to Tsushima islands. Geological data from 5 wells and detailed seismic surveys indicate that sediments in the studied area are divided into 4 stratigraphic groups ranging from Oligocene to Tertiary in age, namely X, H, K, and D groups in ascending order. The oldest X group of Oligocene time comprises paralic sediments including volcanics deposited in the initial stage of basin-formation. N group of mainly lower Miocene time consists of deep marine sediment, representing the highest stage of transgression. Sediments of the K group of middle Miocene time show distinct off-lapping depositional pattern during the basinfilling stage. The youngest D group covers these older groups unconformably. Strong deformation of sediments prior to the deposition of the D group formed many anticlinal structures. Five exploratory wells were drilled at the selected structures, where only minor gas shows were encountered. The area provides the enough palaeotemperature to mature the source rocks at moderate depth.

This paper investigates the methodology to develop a layout of the simulator for measuring and evaluating human sensibility. Since the simulator layout is different from general building layouts in that it is organized in order to communicate systematically between facilities, laboratories to evaluate human sensibility and equipments to support experiments in simulator, two approaches based on eigenvector and cut tree are support to develop a simulator layout. Qualitative input data (relationship chart, space requirements for each laboratory and equipment) are obtained and transformed into quantitative data. The information obtained by two approaches provides several meaningful clues to generate the simulator layout. The simulator layout is presented based on the obtained information by two approaches. Extracted quantitative data by using eigenvector and cut tree are meaningful of generating the simulator layout.

As national income increases, consumers began to place a great deal of weight on products or quality of their life. They would like to have products which are more convenient to use and could meet their emotional desire in addition to its basic functional requirements. An automobile is one of the transportation system for human beings and the factor such as safety or environmentaly-friendly is regarded as important things resulting from it's popularization. In fact, domestic design technology leaves much to be desired compared with excellent manufacturing techniques. For this reason, some problems, like lowering of usage, could be caused by introducing technological data as it is from overseas. A survey of domestic car users has found that the most preferred condition (step height) is 460~495cm when they get in and out of their car. Men use their visual information and then get in the car, taking motion fit for each condition when automobile condition is changed. In other words, men get in cars actively within the range of conditions used for this study. These results were found from a motion study, when getting in a car, and checking the possibility of getting injury in accordance with the change of condition as well.

박세진,한정훈,문영식,Park, Sejin,Han, Jeong Hoon,Moon, Young Shik 한국정보통신학회 2020 한국정보통신학회논문지 Vol.24 No.11

With the development of computer vision systems, many advances have been made in the fields of surveillance, biometrics, medical imaging, and autonomous driving. In the field of autonomous driving, in particular, the object detection technique using deep learning are widely used, and the paved road detection is a particularly crucial problem. Unlike the ROI detection algorithm used in general object detection, the structure of paved road in the image is heterogeneous, so the ROI-based object recognition architecture is not available. In this paper, we propose a deep neural network architecture for atypical paved road detection using Semantic segmentation network. In addition, we introduce the multi-scale semantic segmentation network, which is a network architecture specialized to the paved road detection. We demonstrate that the performance is significantly improved by the proposed method. 컴퓨터 비전 시스템의 발달로 보안, 생체인식, 의료영상, 자율주행 등의 분야에 많은 발전이 있었다. 자율주행 분야에서는 특히 딥러닝을 이용한 객체인식, 탐지 기법이 주로 사용되는데, 자동차가 갈 수 있는 영역을 판단하기 위한 도로영역 인식이 특히 중요한 문제이다. 도로 영역은 일반적인 객체탐지에서 활용되는 사각영역인식과는 달리 비정형적인 형태를 띠므로, ROI 기반의 객체인식 구조는 적용할 수 없다. 본 논문에서는 Semantic segmentation 기법을 사용한 비정형적인 도로영역 인식에 맞는 심층 신경망 구조를 제안한다. 또한 도로영역에 특화된 네트워크 구조인 Multi-scale semantic segmentation 기법을 사용하여 성능이 개선됨을 입증하였다.

박세진,이호규,박종선,김철우,Park, Sejin,Lee, Hokyu,Park, Jongsun,Kim, Chulwoo 한국전기전자학회 2014 전기전자학회논문지 Vol.18 No.1

이 논문은 산소 포화도 측정을 위하여 설계되는 아날로그 프런트 엔드의 설계 기술 및 디자인 방법에 관한 것이다. 센서로부터 출력되는 데이터를 이용하여 산소포화도를 계산하기 위해서는 센서의 포토다이오드에서 흘려주는 전류 데이터를 전압 데이터로 바꿔주는 것이 필요하다. 설계된 아날로그 프런트 엔드는 센서로부터 출력되는 전류 데이터를 여러 가지 전압 이득을 가지는 형태로 후방의 아날로그 디지털 변환기에 전압을 전달하는 역할을 한다. 설계된 회로는 $0.11{\mu}m$ CMOS공정을 이용하여 설계되었으며, $0.174mm^2$의 면적을 차지한다. This paper describes the design technique and the method of analog front-end to measure the saturation of hemoglobin with oxygen sensor. To process the $SpO_2$ value from the sensor, the current data from the sensor should be converted into voltage domain. Designed analog front-end usually converts the current data from the sensor into voltage domain data to pass it on analog-to-digital converter called ADC with a different level of gain characteristics. This circuit was fabricated in a $0.11{\mu}m$ CMOS technology and has 4 level of gain properties. The occupied area is $0.174mm^2$.

박세진,한건연,최현구,Park, Se Jin,Han, Kun Yeun,Choi, Hyun Gu 대한토목학회 2013 대한토목학회논문집 Vol.33 No.5

예상하지 못한 자연 현상으로 인해 붕괴될 가능성을 항상 내포하고 있으며 특히 댐 하류부 지역이 인구밀집 지역이거나 중요 국가 시설물이 위치하고 있는 경우에는 인명 및 재산피해 등 막대한 손실을 초래할 수 있다. 지금까지의 연구는 단독댐 붕괴에 따른 홍수파 해석에 대한 연구는 많이 있었으나 세계적으로 유명한 테네시강 등의 순차적 댐이나 우리나라의 북한강 상류로부터 연속으로 이어진 댐 등에 대한 붕괴 홍수파 해석에 대한 연구는 미흡한 실정이다. 따라서 본 연구의 목적은 순차적 댐 붕괴 홍수파 해석을 통해 순차적 댐 붕괴 첨두유량을 계산하고 하류부에서의 홍수파 전파상황을 예측할 수 있는 해석기법을 제시하는데 있다. 이를 위해 DAMBRK를 이용하여 실제 붕괴 사례 중 순차적 댐 붕괴 사례인 Lawn Lake Dam에 대하여 붕괴 홍수파 해석을 실시하여 댐 붕괴 홍수파 해석 모형의 적절성을 검증하였다. 이를 기초로 하여 가상의 극한홍수에 대하여 국내의 A 댐에 대하여 순차적 댐 붕괴 홍수파 해석을 실시하여 홍수파 전파상황을 예측하였으며, 범람 중요 지점에 대하여 2차원 홍수범람해석을 수행하여 1 2차원 홍수파 해석을 비교 분석한 결과 적합도가 90%를 상회하여 1차원 순차적 댐 붕괴 모의의 정확성을 확인할 수 있었다. 이는 순차적 댐 붕괴와 관련된 하천에서의 방재대책 수립을 위한 기본자료를 제공하는데 기여할 수 있을 것으로 판단된다. Dams always have the possibility of failure due to unexpected natural phenomena. In particular, dam failure can cause huge damage including damage for humans and properties when dam downstream regions are densely populated or have important national facilities. Although many studies have been conducted on the analysis of flood waves about single dam failure thus far, studies on the analysis of flood waves about the sequential failure of dams are lacking. Therefore, the purpose of this study was to calculate the peak discharge of sequential failure of dams through flood wave analysis of sequential failure of dams and this analysis techniques to predict flood wave propagation situation in downstream regions. To this end, failure flood wave analysis were conducted for Lawn Lake Dam which is a case of sequential failure of dams among actual failure cases using DAMBRK to test the suitability of the dam failure flood wave analysis model. Based on the results, flood wave analysis of sequential failure of dams were conducted for A dam in Korea assuming a virtual extreme flood to predict flood wave propagation situations and 2-dimensional flood wave analysis were conducted for major flooding points. Then, the 1, 2-dimensional flood wave analysis were compared and analyzed. The results showed goodness-of-fit values exceeding 90% and thus the accuracy of the 1-dimensional sequential failure of dams simulation could be identified. The results of this study are considered to be able to contribute to the provision of basic data for the establishment of disaster prevention measures for rivers related to sequential failure of dams.

하천과 제내지를 연계한 2차원 홍수범람 해석체계 구축 및 남강유역에의 적용

박세진,최현구,허윤형,한건연,Park. Se-Jin,Choi. Hyun-Gu,Huh. Yun-Hyoung,Han. Kun-Yeun 한국방재학회 2011 한국방재학회논문집 Vol.11 No.6

최근 태풍 및 집중호우로 인하여 하천 제방의 붕괴 및 월류 발생 확률이 증가하면서 제내지에서의 많은 인명손실과 극심한 재산피해 뿐만 아니라 사회적 문제까지 야기되고 있다. 따라서 홍수 예 경보 및 피난대책 수립을 위해서는 홍수 범람 구역에 대한 제방 붕괴 및 월류지점 파악과 해당 지점에서의 제방붕괴폭, 붕괴시간 등을 통한 범람범위의 정확한 추정이 필요하다. 이러한 홍수범람구역의 정확한 추정을 위해서는 대상지역의 수문, 지형, 토지이용현황 등이 중요한 요소이나 실제로 피해를 일으키는 요인은 홍수파로 제방붕괴에 따라 제내지로 유입되는 홍수파의 흐름을 파악하는 것이 무엇보다 중요하다. 본 연구의 목적은 이상홍수 및 국지성 호우에 의해서 댐 및 하천 제방의 붕괴로 인한 제내지에서의 비상상황 발생에 대비하여 하도 내 홍수 해석을 실시함으로써 피해 예상지역 내 주민의 생명과 재산을 보호하기 위함에 있으며, 또한 제내지에서의 침수분포양상의 모의 및 해석을 수행하여 홍수파로 인한 제내지에서의 침수범위, 침수위, 침수시간 등을 예측하고 피해예상규모를 산정하는 것이다. 이를 위해 남강 유역을 대상으로 1차원 부정류 모형인 FLDWAV모형을 이용하여 하천에서의 홍수파 해석과 제방의 붕괴양상을 고려하여 제내지 및 제외지의 수위를 산정하고 붕괴에 따른 범람 수문곡선을 유도하였다. 이를 기초로 하여 2차원 범람 모형에 적용하여 실측 제방 붕괴 지점에서의 홍수파 전달특성을 검토하였으며 제내지의 침수범위, 침수시간, 침수위 등을 계산하여 실측 자료 및 홍수흔적과의 비교 검토한 결과 90%를 상회하는 적합도를 나타내었다. 그리고 같은 지역에서 200년 빈도의 극한상황을 가정하여 범람범위를 산정하였으며, 이 결과는 수방제 및 홍수피해 경감대책 수립에 기여할 수 있을 것으로 판단된다. Due to the recent proliferation of hurricanes and heavy rains, occurrence probability of the collapse of river banks and overflow has increased and has brought about large loss of life and severe property damage in lowland. It is imperative information related to the collapse of levee and overflow systems, flood inundation ranges and overflow spots be generated. Real damage causes include flood waves; understanding streams of flood waves as they flow into the lowland is vitally important. The purpose of this study is to generate data that will protect life and the property of residents in damage areas. Flood analysis is preformed to prepare for emergency situations in lowland due to the collapse of dams and river banks due to extraordinary foods and severe rains. Additionally, through simulation and analysis related to flood distribution patterns in lowland, forecasted inundation depth and time, range of flood, and estimated size of damage expectation can be generated. Data targets include the Nam River watershed using the FLDWAV model. Calculating the water level in lowland and introducing flooding hydrograph are vital to success. This is all related to the collapse of river banks and takes into consideration analysis of flood waves and collapse patterns of river banks. Using this data to create a two-dimensional flood model and by examining flood wave transfer characteristics at the point of real bank collapse, progress can be made. Calculating the range of flood, inundation depth and time in lowland, comparing and reviewing results with actual data and flood marks that showed the goodness of fit is over 90% is key. Calculate the range of flood data by assuming extreme situation of 200 years frequency on the same region, these results are able to contribute establishment of flood damage mitigation measures.
