Abstract Polyps are well-known cancer precursors identified by colonoscopy. However, variability in their size, appearance, and location makes the detection of polyps challenging. Moreover, colonoscopy surveillance removal highly operator-dependent procedures occur a complex organ topology. There exists high missed rate incomplete colonic polyps. To assist clinical reduce rates, automated methods for detecting segmenting using machine learning have been achieved past years. major drawback...
Software-defined radio (SDR) belongs to an emerging class of applications with the processing requirements a supercomputer but power constraints mobile terminal. The authors developed signal-processing on-demand architecture (SODA), fully programmable that supports SDR, by examining two widely differing protocols, W-CDMA and 802.11A. It meets power-performance separating control data employing ultrawide SIMD execution

Polyps are well-known cancer precursors identified by colonoscopy. However, variability in their size, location, and surface largely affect identification, localisation, characterisation. Moreover, colonoscopic surveillance removal of polyps (referred to as polypectomy ) highly operator-dependent procedures. There exist a high missed detection rate incomplete colonic due variable nature, the difficulties delineate abnormality, recurrence rates, anatomical topography colon. have been several...
This paper proposes a low-power high-throughput digital signal processor (DSP) for baseband processing in wireless terminals. It builds on our earlier architecture-Signal On Demand Architecture (SODA)-which is four-processor, 32-lane SIMD machine that was optimized WCDMA 2 Mbps and IEEE 802.11a. SODA has several shortcomings including large register file power, wasted cycles data alignment, etc., cannot satisfy the higher throughput lower power requirements of emerging standards. We propose...
Colorectal cancer is one of the most common cancers with a high mortality rate. The determination microsatellite instability (MSI) status in resected tissue vital because it helps diagnose related disease and determine relevant treatment. This paper presents two-stage classification method for predicting MSI based on deep learning approach. proposed pipeline includes serial connection segmentation network network. In first stage, tumor area segmented from given pathological image using...
In this paper, we discuss the implementation of BCH decoder Chien search algorithm on a SIMD style application specific instruction set processor with minimum memory footprint and processing time degradation. We minimize its usage by deriving computation rule, which is used to efficiently generate consuming primitive elements their power terms upon datapath, instead storing all pre-computed in memory.

To evaluate the amount patterns loss resulting from in cavity (MEC) external auditory canal (EAC) surgery. Method. We obtained pure tone thresholds bone (BC) air conduction (AC) up to 12 weeks 17 patients who had minimal pathology. observe effects only EAC as cases explorative tympanotomy or stapes surgery, BC AC threshold were 18 volunteers. terms average (PTA)...
Considerable work has been devoted to studying flexible computation structures for the physical layer of a software defined radio (SDR) terminal. However there almost no research on protocol processors upper protocols such as media access control (MAC) and link protocol. A general purpose processor (GPP) is sufficient processing single mode However, in case multi-mode system required SDR, very wide set possibilities MAC layer. In principle these too could be handled by GPP. we show that...
Virtual Reality is broadly recognized as an "empathy machine". This reputation due to the feeling of 'presence' that it provides users, which sensation being bodily present in a space, even when space virtual. The possibility complete immersion attracts many creators looking induce empathy and awareness about most diverse subjects. One first types VR non-fiction productions be released was morally sensitive humanitarian documentary genre. research aims explore how differ from non-VR with...
The pulsatile tinnitus is characterized by a rhythmic sound that synchronous with the patient’s heart beat. Accurate diagnosis imperative, because in many patients, treatable underlying etiology can be identified. Sigmoid sinus diverticulum known to one of causes venous tinnitus, but rarely reported literature. We experienced case sigmoid 58-year-old female presenting tinnitus. So we report this review (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:734-7)
Recently, research and interests in pilotless radio-controlled quadcopters have increased due to military, hobby, air-photo applications. However, are fragile can very easily break when they crash. Therefore, it is necessary create a protective device such that these devices protect the main board, motor, propellers from outside impacts. In this paper, for quadcopter designed form of circle disperse shock. Also, dropping impact simulation was performed verify be efficiently protected using...
In this study, we propose an optimal method for monitoring the key electrophysiological sign, Lateral Spread Response (LSR), during microvascular decompression (MVD) surgery hemifacial spasm (HFS). Current methods and interpretations of LSR remain unclear, leading to potential misinterpretations undesirable outcomes." We prospectively collected data from patients undergoing MVD HFS, including basic demographics, clinical characteristics, surgical outcomes. Stimulation intensity was escalated...
In this paper, we develop a model for detecting defects in fabric products based on an object segmentation algorithm, including novel image data augmentation method to enhance the robustness. First, vision-based inspection system is established collect of products. The three types defects, such as hole, stain, and dyeing defect, are considered. To defect detection accuracy robustness, method, referred defect-area cut-mix, proposed. shapes that same each extracted using masks, then they added...

국가평생교육진흥원이 시작한 온라인 강좌 K-MOOC는 대학생 및 일반인의 평생교육을 목적으로 하며 이에 따른 주요 성과 지표는 수강률과 이수율이다. 하지만, 본 사업이 이후 500여 개의 강좌가 개설되었지만, 초기 수강등록 수에 비해 낮은 이수율이 문제로 인식되고 있다. 최근 강좌의 이수율에 대한 연구가 진행되고 있으나 여전히 미흡한 실정이다. 이에, 연구는 2018년 2학기, 2019년 1학기에 진행된 K-MOOC “애니메이션 영화의 혼성적 연출특성”을 대상으로 학습동기와 이수율 간의 상관관계를 분석하고자 한다. 이를 위한 연구의 전개는 첫째, 교육의 특성과 학습동기에 대해 문헌을 중심으로 고찰하고, 하울(Houle)의 ‘학습 지향적’, ‘목적 ‘활동 지향적’의 세 가지 강영민, 박주호, 그리고 이효진(2018)의 7개 참여 동기 요소, 변문경과 조문흠(2017)의 10가지의 수강 동기를 기초로 하여, 10가지 학습동기 유형을 도출하였다. 둘째, 기준으로 애니메이션...
본 연구는 도시정비사업 소요기간에 영향을 주는 요인, 특히 재개발과 재건축사업에 대하여 분석한다. 분석은 정비구역의 특성요인과 거시경제 요인으로 나누어 살펴보고 이러한 영향요인에 시기별로도 차이가 있는지 함께 분석 자료는 통계청의 정비사업현황 기초자료를 기반으로 하고, 재건축사업별, 정권시기별, 사업초기로 STATA 프로그램을 사용하여 비교 분석한다.분석결과 요인은 정비사업에 지속적으로 미치는 것으로 나타난다. 가장 큰 요인으로는 시행용적률로 확인된다. 재개발사업은 재건축사업보다 더 다양한 요인의 받는 확인되고, 재건축사업은 정비구역 특성에 기인한 원인이 유효한 영향요인으로 대한 정부규제 강도에 따른 요인분석에서는 규제가 강한 상황이 약한 상황보다 요인에 의해 분석된다. 연구의 시사점은 재개발ㆍ재건축 사업을 위한 사업특성과 기간별 상황을 고려한 정교하고 차별화된 정책 및 관리가 필요하다는 것을 시사한다.
In this paper, we propose a processor which is optimized for idle mode operation of software defined radio (SDR) terminal. Since SDR terminal spends most its time in the mode, reducing power consumption directly translates to longer standby time. Workload analysis operations contemporary standards showed that these are dominated by FIR filtering, can be easily parallelized. This was used design processor. The key architectural components an SIMD unit parallel computations dominate workload,...
