한국 영어교육은 정치적 상황에 많은 영향을 받아왔다. 특히 초창기에는 그 영향이 지배적이었다. 이에 본 연구에서는 구한말, 일제시대, 그리고 미군정기로부터 1955년 제1차 중등교육과정이 발표되 기 전까지 시기의 영어교육에 미친 정치적 요인을 분석하고자 한다. 구한말은 조선왕조가 쇄국정치 를 폐지하고 일본, 미국 등과 통상조약을 맺으면서 문호를 개방하여 영어가 소개된 시기이다. 이는 한국 영어교육이 처음 시작된 시기로서, 한국 근대화를 추구한 고종과 선각자, 또한 기독교 전파라는 종교적 목적을 가졌던 미국 기독교... -

.한국에서의 경찰제도는 국가경찰의 형태로 운영되어와 획일적이고 중앙집중식의 경찰활동에 대한 거부감이 전반적으로 있어왔다. 그러나 지역주민의 의사에 따른 자율규율에 의한 다원적 민주주의를 실현하고 국민의 기본권을 실질적으로 보장하기 위하여 지난 1995년 지방자치단체의 장과 지방의회 의원의 동시선거가 시행되어 온 이래 10여년이 흘렀다. 그러나 지방자치제도가 시행되기 이전부터 자치경찰제도에 대한 논의는 지속적으로 이루어져 왔다. 자치경찰제에 있어서 주요쟁점의 핵심사항은 자치경찰제를 도입하는 것의... -
구술성과 기록성의 관계에 대한 영어권 학자들의 초기 탐구에 대한 소고
한국구비문학회 구비문학연구 2014, 제 38집 2 29-63 (35 pages)
서양 학계에서는 구술성과 기록성의 관계에 대해서 오랜 세월동안 논의되어 왔으나 현 대 논의는 1960년대에 시작됐다고 볼 수 있다. 본 연구는 초기 미국?캐나다?영국 학자들의 대표적인 이론을 정리하여 이 분야에 기본이 되는 서양 이론을 이해하는 데에 도움이 되고 자 한다. 구술성과 기록성의 관계에 대한 현대 연구의 출발점을 설정하자면 로드의 The Singer of Tales가 출판된 1960년이라고 할 수 있는데 그는 밀만 패리의 연구에 이어 슬라브 구비 서사시를 연구하였으며 후대 학자들에게 영감을 주는 구전 정형어구 이론을... -

일반적으로 감시영상에서 움직이는 물체들은 배경빼기 혹은 프레임 차를 이용하여 추출된다. 하지만 객체에 의해서 만들어지는 그림자는 심각한 탐지의 오류를 야기시킬 수 있다. 특히, 도로 상에 설치된 감시카메라로부터 획득된 영상으로부터 차량 정보를 분석할 때, 차량에 의해서 생성되는 그림자로 인하여 차량의 모양을 왜곡시켜 부정확한 결과를 만든다. 때문에 그림자의 제거는 감시 영상 내에서의 정확한 객체 추출을 위해서 반드시 필요하다. 본 논문은 도로감시영상 내에서 움직이는 차량의 차종판별 성능을 향상시키기 위한... -

in five steps: segmentation, small region elimination, region rectangularization, region merging and region deletion. First, we segment road image by a threshold value. Then, we eliminate useless small regions to extract vehicle region, and perform region rectangularization. Finally, we extract vehicle region of each lane of the road by region merging and deletion. This method has the advantage of measuring road congestion without additional information such as background images. But this method... -

영상 내에서 이동하는 객체를 추출하는 전경 분리 방법은 객체의 일치 추적 및 인식에 있어서 필수적인 기술이다. 하지만 이동하는 객체 주변에 그림자가 발생하는 경우 이러한 전경 분리 방법에서는 그림자도 전경 영역으로 잘못 판단하여 분리하게 되어 이동 객체의 정확한 형태를 파악하거나 위치를 추정하기 어려운 문제가 있다. 본 논문에서는 이러한 문제를 해결하기 위하여 색상 정보를 이용하여 그림자를 모델링하고 이를 통해 전경 영역 내의 그림자 화소를 Bayesian 분류법에 따라 제거하는 방법을 제안하였다. 특히 제안하는...
