The background subtraction technique finds moving objects and reconstructs the background from video sequences. The background subtraction has extensive real-world applications. Most of the background subtraction studies have focused on increasing the accuracy while reducing the complexity. Though few studies have appraised the accuracy of the background subtraction methods, the researchers have not measured the computational complexity of the methods. Thus, in this study, our main goal was to measure the accuracy and computational complexity of the background subtraction approaches. This study can be used in industry and academy. Also, we implemented and assessed the performance of the three different types of background subtraction algorithms such as the cluster-based method, the statistical-based method, and the sample consensusbased method. We mainly used the F-measure with other confusion metrics, which are the most accepted criteria to assess the segmentation accuracy of the background subtraction algorithms. Also, we evaluated the complexity in terms of the memory usage per pixel and the number of frame display per second for the CDD-2012, CDD-2014, and Carnegie Mellon datasets. The experimental data are presented in the table in Section 4 to show the accuracy and computational complexity. 배경 분리 알고리즘은 비디오 시퀀스에서 배경을 재구성하여 움직이는 객체를 찾아내기 위한 기술로, 광범위한 응용 분야에 활용되고 있다. 배경 분리 알고리즘의 연구는 주로 복잡도를 줄이면서 정확성을 높이는 데 중점을 두고 있으나, 복잡도를 측정하거나 정확도를 평가하는 방법에 대한 연구는 상대적으로 미비한 상태이다. 따라서, 본 연구에서는 산업 및 학술적으로 모두 사용 가능한 배경 분리 알고리즘의 정확도와 계산 복잡도 평가 방안을 제시하고자 한다. 본 논문에서는 클러스터 기반 기법, 통계 기반 기법, 표본 합의 기반 기법의 세가지 종류와 배경 분리 알고리즘을 구현하고 평가한다. 특히 배경 분리 알고리즘의 분할 정확도를 평가하는데 가장 적합한 방법인 F-measure를 다른 혼합 지표와 함께 사용하였으며, CDD-2012, CDD-2014, 카네기멜론의 데이터시트를 픽셀당 메모리 사용량, 초당 프레임 수로 복잡도를 평가하여 정확도와 계산 복잡도를 나타낸 실험 결과를 본문(섹션 4)에 제시하였다.

저자들은 1986년 인천 길병원 산부인과에서 수술후 병리조직학적으로 확진된 원발성 난관암 1예를 체험하였기에 문헌고찰과 함께 보고하는 바이다. Fallopian tube carcinoma is very rare of female reproductive organs with an incidence of less than 1 % all genital malignancies. A 48 years old, middle aged woman presented with a pelvic mass. Pathologic examination of the resected specimen revealed a primary adenocarcinoma of the left fallopian tube. We have experienced this case and reported with brief review of literature.
공공기관 정보기술 성과 평가모형에 관한 연구 : 타당성과 균형성의 관점
호진원,김충영 한국정보사회진흥원 2009 정보화정책 Vol.16 No.1
본 연구에서는 전자정부 관련 문헌연구 결과와 정보화사업의 평가를 위해서 개발된 성과지표들을 토대로 통합 성과평가 모형을 제시하였다. 본 평가모형의 성과지표는 정부부처의 전산 담당자들을 대상으로 실시된 설문조사에서 그 중요성이 입증되었으며 요인분석을 통해 모든 성과지표를 5개의 평가영역으로 분류하고 각 평가영역의 타당성을 검증하였다. 또한 IT BSC 방법에서 제시하는 4개 평가영역과 비교할 때 기술적 관점이 추가된 것을 제외하면 거의 동일한 것으로 나타났다. 따라서 본 평가모형의 균형성도 확보된 것으로 판단된다. 본 모형을 토대로 기존의 성과평가 방법들을 비교분석한 결과 국내의 평가모형들은 평가의 균형측면에서 다소 미흡한 것으로 나타났으며. 이에 대한 시사점을 제시하였다. This study suggests an integrated model for evaluating IT performance in public organizations, on the basis of various evaluation criteria both developed in e-government projects and found to be important by the previous studies. All the criteria for the integrated model proved to be important by the survey of the workers who are responsible for IT in their organizations. The model for this study is almost the same as the IT-BSC, except that this model includes additionally the technologcal perspective, which is supposed to examine the technological quality of IT-related services. This study also compares the model with the evaluation methods which have been used in public sectors. This study explains the implications of the findings and also suggests what should be done for the enhancement.

The purpose of this study is to identify the status of progressive parties through studying the changes of those parties in Korea. The main part of this study consists of 4 chapters as follows. Chapter deals with the theoretical considerations of the progressive party. Chapter deals with the concept and ideological characteristic of the progressive parties in Korea. Chapter deals with the progressive parties before the 5th Republic in Korea. Chapter deals with the progressive parties under the 5th Republic in Korea. The progressive party, which has the relative concept to the conservative party in Korea, advocates not the Marx-Leninism but the Social democracy or the Democratic Socialism. Especially, the progressive parties in Korea are based on the moderate socialism, democracy and nationalism. The progressive movement in Korea, which had begun under the japanese colonial rule, was continued by the party activity. The progressive parties have experienced the depressed period 3 times from the 8·15 Liberation to the collapse of the 4th Republic. But under the 5th Republic, the progressive parties entered on the system-accepting step. Because the activities of progressive parties were accepted more or less to absorb those into the system. Neverthless the progressive parties are estimated that they are the government patronized parties or they are short of the practical will in that time. The progressive parties in Korea have two limitations which are the weakness of mass supporting base and the indistinctness of ideological direction. But now the necessity of the progressive parties is increasing more and more in Korea. In conclusion, as the parliamentarism is developed and the party politics is settled with the democratization, it will be possible that the progressive parties develop to speak for the estranged.
