Deep learning is used in various fields, especially the YOLO algorithm, which is one of the many deep-running frameworks, has very fast speed and accuracy that does not lag behind other frameworks. This paper includes a central control system for detecting and recognizing vehicle license plate using YOLO, identifying the vehicle type of the parked vehicle on the parking lot, and checking the parking position of each vehicle in the parking lot based on the recognized car number We intend to facilitate comprehensive parking vehicle management.

Purpose: This study was conducted to introduce the initial experiences with transurethral bipolar plasma vaporization of the prostate (TBPVP) using ‘mushroom’ vapo-resection electrode for the treatment of benign prostatic hyperplasia (BPH) in Korean men. Materials and Methods: We retrospectively analysed the clinical data of 42 consecutive patients underwent TBPVP performed by a single surgeon between October 2009 and April 2011. The patients were assessed preoperatively and perioperatively, and were followed at 2, 4, and 8 weeks postoperatively. Patient baseline characteristics, perioperative data, postoperative outcomes, and major complications were recorded. Results: The mean age at surgery was 70.93±6.26 years. The mean prostate size was 64.10±17.83ml. The mean operation time was 59.40±25.99min, and the mean irrigation fluid volume during procedure was 26,000±10,511ml. The mean duration of catheterization was 3.57±0.94 days. The blood loss was minimal, and there was only 1 transfusion for the patient with ongoing heparization. Compared with baseline, there were significant improvements in IPSS, QoL, Qmax and postvoiding residual urine after surgery. Conclusions: The new TBPVP showed good short-term safety and efficacy for the treatment of Korean patients with BPH.

Tumor thrombus in renal vein or inferior vena cava is rare in patients with renal angiomyolipoma, which is a common benign neoplasm of kidney, especially without potential malignant transformation as epithelioid angiomyolipoma. A 58-year-old female who has known to have a fat containing renal mass in the right kidney, incidentally found by abdominopelvic computed tomography at 2004, was referred to the department of urology with a problem of increased size of the renal mass on computed tomography scan. In this case surgical treatment was clinically necessary due to the invasion of the renal vein and inferior vena cava. The mass and thrombi were excised successfully and the pathology results confirmed that both mass and thrombi are benign angiomyolipoma without any variant histologic differentiation. It must be concerned that vascular invasion can arise from conventional, asymptomatic, and small angiomyolipoma when the physicians decide to have conservative management with surveillance.

라벨인식과 같은 광학 문자 인식은 영상처리를 활용한 컴퓨터 비전의 대표적인 연구분야이다. 본 연구에서는 딥러닝 기반의 라벨인식 시스템을 고안하였다, 생산 라인에 적용되는 라벨인식 시스템은 인식 속도가 중요하기 때문에 기존의 R-CNN기반의 딥러닝 신경망보다 월등히 빠른 오브젝트 검출 시스템 YOLO를 활용하여 문자를 학습 및 인식 시스템을 개발하였다. 본 시스템은 기존 시스템에 근접하는 문자인식 정확도를 제공하고 자동으로 문자영역을 검출 가능하며, 라벨의 인쇄불량을 판독하도록 하였다. 또한 개발, 배포, 적용이 한번에 가능한 프레임워크를 통하여 생산현장에서 발생하는 다양한 이미지 처리에 활용될 전망이다.
