A six months old female infant was admitted with an abrupt onset of high fever and prolonged left hemiconvulsion followed by left hemiparesis. She hand a history of an acute upper respiratory tract infection with improvement two weeks before the admission. On admssion, EEG showed lazy phenomenon in the right side and diffuse slowing on the right hemisphere. MRI revealed multiple patchy lesions of high signal intensity in the right basal ganglia and periventricular areas on the T2WI. There was no abnormal finding on the magnetic resonance angiography. She had recovered with conservative treatmen and the unilateral brain lesions were progressively disappeared on the follow-up MRI studies. These unilateral demyelination lesions might be considered as one of the causes of acute infantile hemiplegia or hemiconvulsion-hemiplegia syndrome(HHS) in infancy, and the ADEM should be included as a cause of HHS.

신용협동조합의 사회공헌활동이 경영성과에 미치는 영향에 관한 연구

박우영 ( Woo-young Park ),박송춘 ( Song-choon Park ),김주환 ( Ju-hwan Kim ) 한국협동조합학회 2016 韓國協同組合硏究 Vol.34 No.1

최근 들어 기업의 사회적 책임에 대한 소비자들의 관심이 높아지면서 기업의 사회공헌활동(CSR)의 중요성 또한 높아지고 있다. 기업의 사회적 책임에 대한 요구가 날로 증대하면서 사회공헌활동은 기업에 있어 선택이 아니라 필수가 되고 있다. 비영리조직인 신용협동조합(이하 ‘신협’이라 한다.)의 사회적 책임은 일반 영리기업의 사회적 책임과는 다르다. 신협의 경우, 신협의 이념 자체에 사회적책임과 지역사회공헌활동이 내포되어 있기 때문에 신협의 사회적 책임 이행을 위한 사회공헌활동은 신협업무의 일부로 수행되고 있다. 신협의 사회공헌활동은 정부가 무상으로 제공하는 공공서비스적성격이 강하다. 하지만, 신협은 정부조직이 아니라 조합원들에 의해 소유되는 협동조합으로, 조합원복리증진을 위해 효율적인 경영을 하여야 하고, 이러한 측면에서 사회공헌활동이 신협의 이미지 제고를 통해 영업실적의 개선으로 이어지고 나아가 신협의 가치를 제고하는가에 대한 분석은 매우 중요하다. 본 연구는 다양한 방식으로 수행되는 신협의 사회공헌활동이 신협의 이미지와 브랜드가치, 그리고 궁극적으로 신협의 경영성과에 미치는 영향을 실증분석하였다. 연구결과 기부협찬 방식은 신협의 이미지와 브랜드가치에 영향을 주지 않는 것으로 나타났으며, 궁극적으로는 경영성과에도 영향을 미치지 않는 것을 확인할 수 있었다. 따라서 앞으로 신협의 사회공헌활동은 기부협찬 방식보다는 공익사업과 자원봉사의 비중을 높이는 방향으로 전략적으로 수행될 필요가 있어 보이며 이러한 방향은 신협의 경영성과를 제고하는데도 도움이 될 것으로 판단된다. 지역신협의 개별적인 사회공헌활동 뿐만 아니라 최근 신협중앙회에서 설립한 사회적 협동조합인 신협사회공헌재단의 사회공헌활동 방식도 기부협찬 방식보다 공익사업과 자원봉사의 비중을 높여야 할 것이다. The importance of Corporate Social Responsibility (CSR) activities is increasing rapidly in line with customers’ growing interest in CSR. In the face of escalating demands for corporations to demonstrate social responsibility, CSR activities are no longer considered merely an alternative option for corporations but are viewed as a necessity. The CSR of a credit union is different from that of a profit-pursuing corporation. Since credit union principles include social responsibility and service to communities, the CSR activities of a credit union form an integral part of its business activities and in fact, are similar to the public social services provided by the government for free. However, a credit union is not a public organization; rather, it is a cooperative owned by members and therefore, it needs to be managed efficiently to promote the well-being of its members. That is the reason why it is important to examine whether credit unions’ CSR activities are enhancing their image, brand value, and ultimately, business performance. In line with the above, this study conducts an empirical analysis to examine the effect of various CSR activities in credit unions on their image, brand value, and business performance. The study findings indicate that donations and sponsorship do not serve to enhance credit unions in the aforementioned areas. Instead, the findings suggest that credit unions need to direct the strategic focus of their CSR activities towards public services and voluntary work in the community, which will ultimately contribute to the improvement of their business performance. This strategic direction for CSR activities needs to be adopted, not just by individual credit unions but also by the Credit Union Foundation for CSR established by the National Credit Union Federation of Korea.

본 논문에서는 ART-1 알고리즘을 이용한 개별코드 인식과 PCA 알고리즘을 적용한 주민등록증 인증방법을 제안한다. 주민등록증 영상에서 주민등록번호와 발행일을 추출하기 위하여 Sobel 마스크와 median 필터를 적용하였다. 잡음이 제거 된 영상에 수평 스미어링을 적용하여 주민등록번호와 발행일 영역을 추출하고 반복 이진화를 적용하여 이진 영상을 획득한 후, 이진화 과정에서 손실된 개별 코드의 영역을 복원하기 위해, 수직 스미어링을 적용한다. 영역이 복원된 영상에서 4 방향 윤곽선 추적 알고리즘을 적용하여 개별 코드를 추출하고 얼굴인증을 위해 주민등록증의 형태학적 특징과 얼굴후보 영역의 눈과 입의 위치 정보를 이용하여 얼굴영역을 추출한다. 추출된 주민등록번호와 발행일은 ART-1 알고리즘을 적용하여 주민등록 번호와 발행일을 인식하고 PCA 알고리즘을 적용하여 주민등록증 사진의 얼굴 영역을 인증한다. 제안된 주민등록증 인식 방법의 성능평가를 위해 원본 주민등록증 영상 25개를 대상으로 실험한 결과, 325개의 주민등록번호와 167개의 발행일 중에서 각각 323개와 166개가 인식되었다. 그리고 사진과 얼굴부분을 위조한 주민등록증 25에 대해 얼굴 인증을 실험한 결과, 얼굴 인증에 있어서 효율적인 것을 확인하였다. In this paper, we proposed a recognition system for resident registration cards using ART-1 and PCA algorithm. To extract registration numbers and issue date, Sobel mask and median filter are applied first and noise removal follows. From the noise-removed image, horizontal smearing is used to extract the regions, which are binarized with recursive binarization algorithm. After that vortical smearing is applied to restore corrupted lesions, which are mainly due to the horizontal smearing. from the restored image, areas of individual codes are extracted using 4-directional edge following algorithm and face area is extracted by the morphologic characteristics of a registration card. Extracted codes are recognized using ART-1 algorithm and PCA algorithm is used to verify the face. When the proposed method was applied to 25 real registration card images, 323 characters from 325 registration numbers and 166 characters from 167 issue date numbers, were correctly recognized. The verification test with 25 forged images showed that the proposed verification algorithm is robust to detect forgery.

도덕적 주체 형성과 사회 참여 주체로서의 교회 이해

박우영(Woo-Young Park) 한신대학교 신학사상연구소 2022 신학사상 Vol.- No.197

사회 내 파편화된 관계성 속에서 신앙공동체로서의 교회가 도덕적 주체를 형성하고 실천의 방향성을 제시할 수 있을지 본 논문은 관심한다. 공동체를 통하여 규범과 가치가 공유되고 도덕적 주체의 성품이 형성되며, 그 실천의 방향성이 정의 실현을 위한 사회 참여로 이어져야 한다는 래리 라스무센의 기독교윤리학 이론과 특성은 파편화된 관계성을 넘어서 새로운 생명의 관계성을 창출하는 데 도움이 될 것이다. 라스무센은 공동체가 사회적 관계성의 형태들이며 도덕적 삶의 물질적 현실이라고 이해한다. 하나님 경험에 근거한 교회 공동체가 도덕적 주체로서 정의를 지향하는 사회 참여로 나아가야 하며, 모든 생명의 번성함이란 사회 생태적 정의의 실현을 위한 공동체적 실천은 그의 매우 핵심적인 주장이다. 바로 이 실천을 위한 동력을 찾기 위해 라스무센은 금욕주의, 성례주의, 신비주의, 그리고 예언자적 해방 전통과 같은 기독교의 오랜 영성적 전통들을 재해석함으로써, 현대 사회의 지배적이고 폭력적인 흐름과 파편화된 관계성에 대한 대안적 삶의 방식을 제공하고자 한다. 라스무센의 기독교윤리학에 따르면, 교회는 도덕적인 성찰을 바탕으로 생명공동체의 공공선과 복지를 향한 실천의 주체로 자리매김해야 할 것이다. This thesis raises the question of whether the church as a community of faith can form a moral agent and provide direction for moral practice in the present fragmented society. Larry Rasmussen’s Christian ethics serves as the focal point for this study. Rasmussen points out that norms and values are shared through community. In this sharing the character of a moral agent is formed and the direction of its practice should lead to social engagement for justice in making. This, in turn, will help to create new relationships of life. Rasmussen understands community as our social relatedness and the material reality of the moral life. The church community based on the experience of God must move toward justice-oriented social participation as a moral agent, and the communal practice for the realization of socio-ecological justice is his core argument for the prosperity of all life. To find a radical motivation for this practice, Rasmussen reinterprets the longstanding spiritual traditions of Christianity, such as asceticism, sacramentalism, mysticism, and the prophetic liberative tradition and tries to provide an alternative way of life against the dominant and violent streams and fragmented relationships of the current society. According to Rasmussen’s Christian ethics, the church should be positioned as an active agent of practice for the common good and welfare of the living community based on moral reflection.
