The fad word ``Eu-ri`` has swept across Korea last year. ``Eu-ri`` has been originally used by actor Bo-sung Kim SInce long time ago, but comedian Kuk-ju Lee adapted the fad word at a gag program. Many commercial films are based on the fad word ``Eu-ri`` nowadays. But Bo-sung Kim gets a lot of chances to take a commercial film, although Kuk-ju Lee did an important role on the popularity of the fad word ``Eu-ri``. Besides, Bo-sung Kim doesn``t use the fad word like he has used till now, but borrows Kuk-ju Lee``s style. After focusing on the fact that Lee parodied Kim``s fad word and Kim took many commercial films due to the popularity of the fad word made by Lee, each facts are analyzed from the aspects of each law. From the Copyright Law``s View, copyright cannot be recognized on the fad word ``Eu-ri`` itself. It is required to attain the high extent of creativity to have the valid copyright under the Continental Law system. But fad words, which are too short to contain any value in the usage, barely are recognized to attain copyright. No problem arise from the aspect of demonstration imitation either. Intangible imitation is not acknowledged at Korea. Lee``s parody and Kim``s act on commercial films are also their own demonstration. Besides, the fact that ordinary people might not confuse between Kim and Lee can also be considered, as well as Lee``s creative effort is reflected on the parody. From the Publicity Right``s view. Lee and Kim doesn``t seem to infringe each other``s right. Because not only parody only take a little possession of whole performance but also it IS hard to say that the value is diluted due to repeated exposure. From the Unfair Competition Prevention and Trade Secret Protection Act``s view, Kim``s decision to take commercial films might cause problems. Lee``s parody on the gag program doesn``t consist the competition between Kim. But Kim``s acting similar character with Lee on commercial films might cause unfair competition. Especially, according to the general article which is introduced February 2014, taking commercial film can be categorized as one part of celebrity``s business, and Kim``s taking commercial films can be seem as hijacking a popularity of Lee``s comedy. Taking economic benefit by imitating celebrity``s performance is becoming a serious problem in Korea. Other than Kim``s episode, radio advertisement which imitates fad word was pointed out to infringe celebrity``s right. Adopting the logic which is similar to overtaking right can be also considered as a good method to protect celbrity``s right about their performance.

Pellicle is defined as a thin transparent film stretched over an aluminum (Al) frame that is glued on one side of a photomask. As semiconductor devices are pursuing higher levels of integration and higher resolution patterns, the cleaning of the Al flame surface is becoming a critical step because the contaminants on the Al flame can cause lithography exposure defects on the wafers. In order to remove these contaminants from the Al frame, a highly concentrated nitric acid ($HNO_3$) solution is used. However, it is difficult to fully remove them, which results in an increase in the Al surface roughness. In this paper, the pellicle frame cleaning is investigated using various cleaning solutions. When the mixture of sulfuric acid ($H_2SO_4$), hydrofluoric acid (HF), hydrogen peroxide ($H_2O_2$), and deionized water with ultrasonic is used, a high cleaning efficiency is achieved without $HNO_3$. Thus, this cleaning process is suitable for Al frame cleaning and it can also reduce the use of chemicals.

A 2-month-old male Jeju native black calf with respiratory distress was died and requested to the Veterinary Pathology Laboratory of Jeju National University for diagnosis. Grossly, lungs were focally attached to the pleura and heart with fibrin. Purple red sublobar consolidations were distributed in both apical and cardiac lobes of lungs. Histopathologically, diffuse severe bronchointerstitial pneumonia characterized by multifocal necrotizing bronchiolitis, formation of numerous multinucleated syncytial cells in bronchiolar and alveolar lumens, and diffuse alveolar wall thickening were observed in lungs. Eosinophilic intracytoplasmic inclusions were observed in bronchiolar epithelial cells and syncytial cells. According to reverse transcriptase polymerase chain reaction (RT-PCR), bovine respiratory syncytial virus (BRSV) was detected in the lung of calf. Based on the histopathologic findings and RT-PCR, this calf was diagnosed as BRSV infection. In our best knowledge, this is the first case of BRSV infection in Jeju native black calf.

본 논문에서는 터널 내에서 차량의 운행 상태를 모니터링하기 위하여 차량 검출 및 추적 알고리즘을 제안한다. 제안하는 알고리즘은 세 단계로 이루어진다. 첫 단계는 배경추정으로서 비교적 간단한 Running Gaussian Average (RGA)를 사용한다. 두 번째 단계는 차량검출 단계이며, Adaboost 알고리즘을 적용한다. 상대적으로 먼거리의 차량에 대한 오검출을 줄이기 위하여 차량의 높이별 부분 특징을 이용하여 차량을 검출한다. 물체의 부분 특징들이 임계값 이상이면 차량으로 분류한다. 마지막 단계는 차량추적 단계이며, Kalman 필터를 적용하여 이동하는 물체를 추적한다. 컴퓨터 시뮬레이션을 통하여 제안하는 알고리즘이 터널 내에서 차량 검출 및 추적에 유용한 것을 확인하였다. In this paper, an efficient vehicle detection and tracking algorithm for detection incident in tunnel is proposed. The proposed algorithm consists of three steps. The first one is a step for background estimates, low computational complexity and memory consumption Running Gaussian Average (RGA) is used. The second step is vehicle detection step, Adaboost algorithm is applied to this step. In order to reduce false detection from a relatively remote location of the vehicles, local features according to height of vehicles are used to detect vehicles. If the local features of an object are more than the threshold value, the object is classified as a vehicle. The last step is a vehicle tracking step, the Kalman filter is applied to track moving objects. Through computer simulations, the proposed algorithm was found that useful to detect and track vehicles in the tunnel.

선박과 선박, 선박과 육상 관제소간에 선박의 위치정보 등을 자동 송수신하여 선박 간의 충돌 방지 및 해난 수색 구조 활동을 지원하기 위하여 선박 자동 식별 장치인 AIS(automatic identification system)을 채용하고 있다. 그리고, 항만의 관제시스템은 선박 AIS와 연계하여 선박의 통항을 관리한다. 효율적인 통항관리를 할 수 있도록 AIS 연동하는 선박 인식 및 표출 시스템이 요구되고 있다. 본 논문에서는 카메라로부터 입력된 해상 또는 항만 영상에 대하여 배경추정을 이용한 영상기반의 선박검출과 검출된 해당 선박의 AIS 신호를 연동하여 모니터 상에 표출하는 AIS 연동 선박검출 방법을 제안한다. 해상 또는 항만에서 실시간 입력되는 영상에 대하여 선박 검출 실험을 하였다. 시뮬레이션 및 실험결과 제안하는 알고리즘이 항만의 선박 관제에 효과적으로 활용할 수 있음을 확인하였다. To support anti-collision between ship to ship and sea-search and sea-rescue work, ship automatic identification system(AIS) that can both send and receive messages between ship and VTS Traffic control have been adopted. And port control system can control traffic vessel service which is co-operated with AIS. For more efficient traffic vessel service, ship recognition and display system is required to cooperated with AIS. In this paper, we propose ship detection system which is co-operated with AIS by using background estimation based on image processing for on the sea or harbor image extracted from camera. We experiment with on the sea or harbor image extracted from real-time input image from camera. By computer simulation and real world test, the proposed system show more effective to ship monitoring.
화염의 색상 및 동적 특성을 이용한 FFmpeg 기반 실시간 화염 검출
김현태,Kim, Hyun-Tae 한국전자통신학회 2014 한국전자통신학회 논문지 Vol.9 No.9
본 논문에서는 고화질 IP 카메라로부터 입력되는 영상으로부터 실시간으로 화염을 검출할 수 있는 시스템을 제안한다. 먼저 FFmpeg 라이브러리를 이용하여 비디오 파일을 오픈하는 것처럼 IP 카메라로부터 전송되는 RTSP 스트림을 직접 오픈한다. 두 번째는 입력영상으로부터 혼합 가우시안 모델을 이용하여 배경영상을 추출한다. 그 다음에는 입력 영상과 배경영상간의 차신호로부터 전경영상을 구한다. 분리된 전경영상은 수학적 모폴로지 연산을 거쳐 후보영역으로 간주한다. 후보영역의 색정보와 화염의 동적 특성을 분석하여 최종적으로 화염을 검출한다. 실험 결과를 통하여 제안하는 방법이 화염을 검출하는 데 효과적인 것을 보인다. In this paper, we propose a system which can detect the flame in real time from the high-quality IP camera. First, open directly the RTSP streams transmitted from the IP camera using the library FFmpeg as opening a video file. The second thing is to extract the background images from video signal using Gaussian mixture model. Then the foreground images are obtained through subtracting operation between the input image and the background image. Separated foreground image through a mathematical morphology operation are considered as candidate area. By analysing colour information and dynamic characteristics of the candidate area, flame is determined finally. Through the experiments with input videos from IP camera, the proposed algorithms were useful to detect flames.
