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.

Acute kidney injury (AKI) is associated with mortality and may lead to increased medical expense. A modified criteria (pediatric RIFLE [pRIFLE]: Risk, Injury, Failure, Loss, and End-stage renal disease) has been proposed to standardize the definition of AKI. The common causes of AKI are renal ischemia, nephrotoxic medications, and sepsis. A majority of critically ill children develop AKI by the pRIFLE criteria and need to receive intensive care early in the course of AKI. Factors influencing patient survival (pediatric intensive care unit discharge) are known to be low blood pressure at the onset of renal replacement therapy (RRT), the use of vasoactive pressors during RRT, and the degrees of fluid overload at the initiation of RRT. Early intervention of continuous RRT (CRRT) has been introduced to reduce mortality and fluid overload that affects poor prognosis in patients with AKI. Here, we briefly review the practical prescription of pediatric CRRT and literatures on the outcomes of patients with AKI receiving CRRT and associations among AKI, fluid overload, and CRRT. In conclusion, we suggest that an increased emphasis should be placed on the early initiation of CRRT and fluid overload in the management of pediatric AKI. 소아에서 급성 신손상의 흔한 원인들로는 신허혈, 신독성 약물들, 그리고 패혈증 등이 있으며, 신대체요법 시작시의 저혈압, 신대체 요법 동안 승압제의 사용, 그리고 신대체 요법 시작시의 수액 과부하 정도가 환자의 생존(소아 중환자실 퇴원)에 영향을 미치는 요인들로 알려져 있다. 지속적 신대체 요법의 빠른 시작은 급성 신손상을 가진 환자들에게서 사망률과 예후에 나쁜 영향을 미치는 수액 과부하를 감소시키는 것으로 보고되었다. 이에 저자들은 소아 환자에게서 지속적 신대체 요법의 실제 처방과 급성 신손상, 수액 과부하, 그리고 지속적 신대체 요법간의 연관성 및 치료결과를 살펴보고자 한다. 결론적으로, 급성 신손상을 가진 소아의 치료에 있어서 과도한 수액 과부하가 발생하기 전에 빠른 지속적 신대체 요법의 시작이 필요하다고 제시하는 바이다.

Submerged arc welding method from both sides is generally applied to the welding of main panel manufacturing process during ship construction. The tandem SAW method is applied to improve the productivity. The various weld defects that occur during tandem SAW method are melt through, incomplete penetration, undercut and overlap etc. It could be thought that the reasons for these defects are mainly lack of prediction ability for penetration depth and deposited metal area. In this research, total 5 kinds of welding factors for experiment like current of lead pole, voltage of lead pole, current of trail pole, voltage of trail pole and welding speed are adopted. Weld tests are carried out for the analysis of variation effects of these factors on penetration depth and deposited metal area. Based on the test and analysis results, it is possible to obtain the prediction equation for the effect of these factors on the amount of deposited metal and penetration depth. As per the verification of the results by additional tests, it is confirmed that the prediction equation, include a error margin of ${\pm}2mm$ for penetration depth and ${\pm}10mm2$ for deposited metal area.

Purpose: To help the empirical antibiotics selection in diabetic foot infection patients, we investigated prevalence of microorganisms and their antibiotics sensitivity results. Materials and Methods: Patients who came to our clinics to treat diabetic foot infections with deep ulceration and were followed up more than 6 months until complete recovery were adopted. From March 2006 to June 2009, there were 140 patients who corresponded with such a inclusion criteria. Wound cultures were done by deep tissue or bone debris at first visit to our clinics. Microorganisms which was documented by wound culture and most susceptible antibiotics by minimum inhibitory concentrations were surveyed retrospectively. Results: Microorganisms were confirmed in 113 cases (80.7%). In the other 27 cases (19.3%), there were no cultured microorganisms. In bacterial growth group, there were 72 cases (63.7%) of gram-positive bacteria and 41 cases (36.3%) of gram-negative bacteria. All of them were aerobic microorganisms and there were no anaerobic microorganisms. Methicillin-sensitive staphylococcus aureus was the most common pathogen and accounted for 35 cases (31.0%). As other common pathogens, there were Enterobacter cloacae (11 cases, 9.7%), pseudomonas aeruginosa (10 cases, 8.8%), Methicillin-resistant staphylococcus aureus (10 cases, 8.8%) and enterococcus faecalis (6 cases, 5.3%), and so on. Common susceptible antibiotics in gram positive microorganism were vancomycin (60 cases, 83.3%), teicoplanin (60 cases, 83.3%), nitrofurantoin (60 cases, 83.3%) and ciprofloxacin (53 cases, 73.6%). In gram negative ones, common susceptible antibiotics were imipenem (35 cases, 85.3%), piperacillin/tazobactam (33 cases, 80.5%) and gentamicin (31 cases, 75.6%). Conclusion: Methicillin-sensitive Staphylococcus aureus in gram positive and enterobacter cloacae in gram negative was the most common pathogen in each group. Ciprofloxacin and gentamicin might be adaptable as a first-line empirical antibiotics in infected diabetic foot patients.

Parainfluenza virus 감염은 횡문근융해증의 하나의 원인이 될 수 있다. 횡문근융해증은 지속된 금식기간동안 미토콘드리아 지방산 ${\beta}$-oxidation 장애에 의해 악화될 수 있다. 또한 후기 발생 isovaleric 산증을 가진 환아들에게서 고암모니아혈증이 이화작용을 일으키는 상태 후 발생할 수 있다. 본 케이스는 parainfluenza virus 감염과 후기 발생 isovaleric 산증을 가진 4세 남아가 혼수, 경련 및 심호흡 부전으로 빠르게 진행했던 경우이다. 초기 암모니아와 creatinine kinase는 각각 $385{\mu}Mol/L$과 23,707 IU/L 이었으나 지속적 신대체요법 시행 후 암모니아와 creatinine kinase 수치는 정상으로 돌아왔다. 그러므로 생명을 위협하는 횡문근융해증과 고암모니아혈증을 가진 환아들의 치료에 있어서 즉각적인 지속적 신대체요법의 사용을 권하는 바이다. Parainfluenza virus infection is one of the causes of fatal rhabdomyolysis. Rhabdomyolysis can be aggravated by mitochondrial fatty acid ${\beta}$-oxidation disorders during prolonged periods of fasting. Moreover, in patients with late-onset isovaleric acidemia, hyperammonemia may occur following catabolic stress. In the present report, we describe a case of a 4-year-old boy with parainfluenza virus infection and late-onset isovaleric acidemia that rapidly progressed to coma, seizures, and cardiorespiratory collapse. His serum ammonia and creatinine kinase (CK) levels were $385{\mu}Mol/L$ and 23,707 IU/L, respectively. Continuous renal replacement therapy (CRRT) was initiated using continuous venovenous hemodiafiltration, after which the ammonia and CK levels returned to normal. Thus, we recommend the immediate initiation of CRRT in the management of patients with life-threatening rhabdomyolysis and hyperammonemia.

Urine production is vital for the removal of certain waste products produced by metabolism in the body and for the maintenance of homeostasis in the body. The kidneys produce urine by the following three precisely regulated processes: filtration, reabsorption, and secretion. Urine is composed of water, certain electrolytes, and various waste products that are filtered out of the blood through the glomeruli. The physical features of urine are evaluated carefully to detect any abnormal findings that may indicate underlying diseases in the genitourinary system. A change in urine color may indicate an underlying pathological condition, although many of the causes of abnormal urine color are benign effects of medications and foods. A characteristic and specific odor may be the result of a metabolic disease rather than a concentrated specimen or a simple urinary tract infection. Although transient changes in urine output and nocturia are usually benign conditions, persistent abnormal findings require further workup, with a thorough medical history taking. This article presents many of the conditions that physicians may encounter and will help them in the diagnosis and in establishing a treatment plan.

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.

The objective of cache is to reduce I/O access of physical storage device so that user accesses their data faster. Traditionally, the most important metric to measure the performance of cache is hitratio. Thus, when the cache maintains hitratio high, it is regarded as a good cache replacement policy. However, the cache miss latency is different when the storages are heterogeneous. Though the cache hitratio is high, if the cache often misses with low performance disk, then the user experiences low performance. To address this problem we proposed eviction cost estimation based cache management. In our result, the eviction cost estimation based cache management has 10~30% throughput improvement compared with LRU cache management.
