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.

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.

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.

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.

최근 원음 반주기에 대한 관심이 증가됨에 따라 고가의 스튜디오 직접 녹음 방법 대신 보다 저렴한 방법을 시도하고 있다. 그 구체적인 방법으로는 가수의 음악 앨범에서 가수의 목소리만 제거하여 원음 반주 음원을 만드는 것이다. 본 논문에서는 스테레오로 녹음된 반주음악에서 보컬을 분리하는 시스템을 제안한다. 제안하는 시스템은 두 단계로 구성된다. 첫 단계는 보컬을 검출하는 단계이다. 이 단계에서는 MFCC를 가지고 SVM 방법을 이용하여 입력 신호를 보컬 부분과 비보컬 부분으로 분리한다. 두 번째 단계에서는 보컬 부분에 대해 각 주파수 빈별로 선택적 주파수 차감을 수행한다. 제안하는 방법으로 보컬을 제거한 음악에 대한 청취실험에서 상대적으로 높은 만족도를 보여준다. Recently, According to increasing interest to original sound Karaoke instrument, MIDI type karaoke manufacturer attempt to make more cheap method instead of original recoding method. The specific method is to make the original sound accompaniment to remove only the voice of the singer in the singer music album. In this paper, a system to separate vocal components from music accompaniment for stereo recordings were proposed. Proposed system consists of two stages. The first stage is a vocal detection. This stage classifies an input into vocal and non vocal portions by using SVM with MFCC. In the second stage, selective frequency subtractions were performed at each frequency bin in vocal portions. Listening test with removed vocal music from proposed system show relatively high satisfactory level.

본 논문에서는 출력단 전력의 위상과 크기가 모두 대칭인 새로운 구조의 3-way 전력 분배기를 제안한다. 종래의 일반적인 Wilkinson 전력 분배기의 경우, 3-way 이상의 전력 분배시 격리 특성을 결정하는 저항 소자의 crossover로 인하여 평면형 구조로의 구현이 어려웠다. 반면, 본 논문에서 제안하는 회로는 평면형이면서 격리 저항을 쉽게 장착할 수 있는 장점을 가지고 있다. 그리고 대칭 구조이면서 선로 간 전기적 길이가 동일하므로 출력단 위상차를 위한 별도의 보상 선로가 불필요하다. 제작된 2.4 GHz 대 3-way 전력 분배기는 종래의 구조에 비하여 160% 만큼 개선된 $S_{11}$ 대역폭, 최하22.4 dB의 격리 특성, 그리고 출력 단자간 동일한 위상 특성을 보인다. This paper presents an equal 3-way planar-type power divider. In conventional 3-way Wilkinson dividers, it has been difficult to realize the circuit because of the crossover of isolation resistors. In the proposed divider, the isolation resistors can be easily attached to the planar structure of the divider. In addition, no phase difference is observed at output ports without extra line compensation because of its symmetric structure. The fabricated 3-way divider has a greatly improved bandwidth by 160 % in $S_{11}$, 22.4 dB, min of isolation, and in phase characteristics between output ports at 2.4 GHz of center frequency from measurement.
