중복 자궁(Didelphic uterus)은 두 개의 분리된 자궁체부와 각각의 자궁부속기 및 자궁경부를 가진 뮐러 기형의 한 형태로, 임신 12주에서 16주 사이에 발생하는 여성 비뇨생식기의 발생학적 이상으로 인한 뮐러씨 관의 전체적인 융합의 실패에 의해 생기는 것으로 종종 신장 또는 요로계의 이상을 동반한다고 보고된다. 저자들은 최근 복부에 촉지되는 종괴로 내원하여 내진 및 초음파 검사상 약 10×10cm 크기의 좌측에 치우쳐진 자궁근종으로 진단되어 전자궁 적출술 및 양측 난소난관 절제술 시행 중 중복 자궁, 좌측 신장 무발생 및 동측의 가트너관 낭종 및 일측 자궁에 임신 18주 크기의 자궁 근종이 동반된 1예를 경험하였기에 이를 간단한 문헌 고찰과 함께 보고하는 바이다. Uterine didelphys is a class of congenital Mullerian anomaly, and it is a rare embryonic malformation of genitourinary system of female. Gartner's duct cyst is a remnant of mesonephric duct of female genitourinary system. It is rarely associated with ipsilateral renal agenesis, and have been reported less than 40 cases. We report a case of uterine didelphys associated with ipsilateral renal agenesis and Gartner's duct cyst, which was diagnosed incidentally during operation for huge uterine myoma.

This paper is an exploratory study on the success factors of Defence Quality Management System (DQMS) which is the certification system granted by the military for improving the quality of munitions. DQMS is established by adding military requirements to the ISO standard, thus, we especially focus on the additional requirements to figure out success key factors of DQMS certification. The 51 additional requirements of Korean Defense Specification (KDS) are empirically investigated from 67 companies that acquired DQMS certification. Firstly, we conduct an independent t-tests on 51 additional requirements of KDS 0050-900-3 to determine if there is a difference between an easily certified company and a hard-to-certify company, and obtain 8 requirements such as ‘Internal propagation of performance’, ‘Preparation of documented work instructions’, ‘Work instructions in the workplace’, ‘Documentation of equipment management’, ‘Inventory management’, ‘Packaging and identification’, ‘Guarantee of access to internal audit result for customers’, ‘Notification to the customer for improper product.’ Secondly, we carry out an factor analysis to the 51 additional requirements for classification, and figure out that 4 requirements among the 8 requirements above mentioned are grouped together in the same factor. The 4 requirements are ‘Preparation of documented work instructions’, ‘Work instructions in the workplace’, ‘Packaging and identification’, and ‘Guarantee of access to internal audit result for customers.’ The result of this paper will provide useful information to the company preparing for DQMS.

In this paper, the charateristics of contemporary commanitarianism are investigated. Commanitarianism is a trend of thought which admits the constitutive value of community and systematizes the theory justifying it. This communitarianism, represented by the writers such as Michael Sandel. Alasdair Maclntyre and Charles Taylor, describes community as a body of persons maintaining their identity through the shared self0understanding. Communitarians have systematized their theory in the process of the critique of liberal individualism connected with the moral anarchy of contemporary society and tried to revitalize the civic republican tradition in the West. They claim that 'the right of man' should be substituted by 'the common good'. And they emphasize the values of civic virtue, commumity and public participation. But their theory does not yet seem to possess the clarity as an idea because it does not explicitly explain the scale of commanity and the relation between community and politics. In the metaphysical·metaethical aspects, the communitarian view that liberalism's emphasis on the rights of man has become one of the main elements promoting the moral disorder, seems to be persuasive. However, we can find that the communitarian refutation about the theory of the rights of man itself is insufficent. And in the descriptive aspects. communitarians overemphasize the social and cultural influence on the identity of the individuals. Although the communitarian critique of the moral limits of liberalim is partly acknowledged, the adpotion of communitarian alternatives has to be accessed cautiously. For communitarians, it is necessary to especially develop the theories which can remove the authoritative and totalitarian possibility derived from the collective disposition of communitanianism.
칼라 히스토그램과 변형된 샤프닝 필터를 이용한 개선된 그랩컷 알고리즘에 관한 융합 기술 연구
박종훈,이강성,이상훈 한국융합학회 2015 한국융합학회논문지 Vol.6 No.6
본 논문에서는 기존의 그랩컷 알고리즘을 이용한 객체 검출의 정확도를 향상시키기 위하여 샤프닝 필터를 이용한 영상의 화질을 개선하는 방법을 제안한다. 그랩컷 알고리즘은 사각 윈도우 범위 내에서 객체 추출에 뛰어난 성능을 보이지만, 객체와 배경의 구분이 뚜렷하지 않은 영상에서는 성능이 떨어지는 단점이 있다. 따라서 본 논문에서는 히스토그램 평활화를 통해 밝기 및 선명도를 보강하고, 샤프닝 필터를 이용하여 객체의 경계를 강화하여 기존의 그랩컷 알고리즘보다 객체와 배경의 색상이 비슷한 영상에서 향상된 객체 추출 결과를 보인다. 개선된 그랩컷 알고리즘을 토대로 문자인식, 실시간 객체추적 등 영상처리 융합 기술에서 향상된 결과를 얻을 수 있다. In this paper, we proposed image enhancement method using sharpening filter for improving the accuracy of object detection using the existing Grabcut algorithm. GrabCut algorithm is the excellent performance extracting an object within a rectangular window range, but it has the drawback of the inferior performance in image with no clear distinction between background and objects. So, in this paper, reinforcing the brightness and clarity through histogram equalization, and tightening the border of the object using the sharpening filter look better than that extracted result of existing GrabCut algorithm in a similar image of the object and the background. Based on improved Grabcut algorithm, it is possible to obtain an improved result in the image processing convergence technique of character recognition, real-time object tracking and so on.
