Objectives : To investigate the prevalence and utilization pattern of complementary and alternative medicine (CAM) in individuals with type 2 diabetes. Methods : We conducted a nationwide survey and a total of 535 individuals with type 2 diabetes were asked about their demographic, diabetes-related characteristics and CAM use. We used multiple logistic regression modeling to determine independent predictors of CAM use. Results : Of the 535 subjects, 417 (77.9%) used CAM in last 12 months. The most commonly used modality was red ginseng (17.9%). CAM use was independently associated with being married, northern area residence, higher education and diabetes duration of 3-5 years. More than half(58.3%) of the CAM users used it expecting a better outcome in addition to conventional therapy. Information sources about CAM were mostly friends (36.0%) and family (31.9%), only 28.1% of diabetic patients seek counsel from medical doctors or oriental medical doctors about CAM. Many people perceived CAM as effective (62.7%) and reported side effects only rarely (1.2%). Conclusions : Many diabetic patients used CAM and found it effective, which urges clinicians to pay attention to CAM use of their diabetic patients. Also, further studies are required regarding efficacy and safety about CAM.

章太炎 《文始》의 어원 해설 방식과 유관 글자의 재분류 - 寒部 ‘毌(관)’계열을 중심으로

문수정 중국어문학회 2015 中國語文學誌 Vol.0 No.53

本文旨在通過分析章太炎《文始》的解釋方式以及對漢字的重新分類,確認他對語言文字體系的觀點:以語音爲中心的語言文字觀。我們通過觀察章太炎在《文始》裏面所做的說解方式可以進一步了解他對語言的看法和他的語言文字觀,例如有孳乳、變易、音轉等的術語。他所說的孳乳和變易是指詞的派生過程的,還有以音轉理論來說明從一個語源派生出來的幾套詞語的語義上的連接關係。從這篇著作裏,我們可以看到章太炎認爲當時存在的那些詞和字都是從原始時代存在的少數幾個單詞派生出來的,即一個新字是隨著一個新詞產生而造出來的,還有發音相似的兩個字很可能從一個字派生出來的。他還對說文解字裏面的整個漢字進行重新分類,完成了按照自己設定的新標准建構的新體系。通過分析《文始》的體系和說解方式,我們可以觀察到章太炎具有的以聲音爲中心的語言觀和他對語源的認識。

Purpose: To investigate the effect of amniotic membrane transplantation (AMT) on recurrent herpetic keratitis with unhealed corneal epithelial erosion. Methods: We performed AMT on 5 cases of herpetic keratitis from February 2004 to August 2005. We had applied two layers of fresh amniotic membrane over the corneal lesion and anchored by running suture technique with 10-0 nylon. Results: After AMT, visual acuity improved in 5 eyes of 5 herpetic keratitis patients. In all patients the persistent epithelial erosion was healed and pain was subsided after surgery. Conclusions: The AMT shortened the usage of antiviral agents and antibiotics, increased compliance, and decreased corneal opacity and neovascularization. The AMT is an effective method for managing recurrent herpetic keratitis with unhealed corneal epithelial erosion that are refractory to conventional treatment.

MPEG-2 압축 영역에서 움직이는 객체의 추적 및 해석

문수정,유원영,김준철,이준환,Mun, Su-Jeong,Ryu, Woon-Young,Kim, Joon-Cheol,Lee, Joon-Hoan 한국정보처리학회 2004 정보처리학회논문지B Vol.11 No.1

본 논문에서는 MPEG-2비디오 스트림에서 복호화 과정 없이 압축비디오에서 직접 얻을 수 있는 정보들을 활용하여 움직이는 객체를 추적하고 해석하는 방법을 제안한다. 제안된 방법에서는 먼저 MPEG-2의 움직임 벡터로부터 근사적으로 움직임 플로우(motion new)를 구성하고, 전역 적인 움직임 플로우로부터 일반화된 Hough 변환을 이용 카메라의 기본적인 움직임인 팬(pan), 틸트(tilt), 줌(zoom)량 등을 계산하였다. 계산된 카메라 움직임은 국부적으로 일어나는 객체의 움직임을 보정하는데 사용하였다. 움직이는 객체의 추적은 사용자가 원하는 객체를 바운딩 박스 형태로 정의함으로 시동된다. 이후의 객체의 추적은 카메라 움직임이 보정된 객체의 움직임 플로우를 한 GOP(Group of Pictures)단위로 면적 기여도에 따라 누적하여 추적하였다. 또한 추적오차의 누적을 막기 위해 매 GOP마다 DCT(Discrete Cosine Transform) 정보를 이용하여 초기 바운딩 박스와 매칭을 통해 객체의 영역을 재 설정하였다. 제안된 방법은 압축된 비디오 스트림에서 직접 정보를 얻음으로써 계산속도의 향상을 기할 수 있으나, 압축된 MPEG-2 비디오에서 얻을 수 있는 정보들이 최대 블록 단위이므로 객체의 정의도 블록단위 이상의 객체로 제한되며, 이용한 수 있는 정보가 제한되어 있기 때문에 정확한 객체추적보다는 근사적인 객체추적에 적합하다. This paper proposes a method to trace and interpret a moving object based on the information which can be directly obtained from MPEG-2 compressed video stream without decoding process. In the proposed method, the motion flow is constructed from the motion vectors included in compressed video. We calculate the amount of pan, tilt, and zoom associated with camera operations using generalized Hough transform. The local object motion can be extracted from the motion flow after the compensation with the parameters related to the global camera motion. Initially, a moving object to be traced is designated by user via bounding box. After then automatic tracking Is performed based on the accumulated motion flows according to the area contributions. Also, in order to reduce the cumulative tracking error, the object area is reshaped in the first I-frame of a GOP by matching the DCT coefficients. The proposed method can improve the computation speed because the information can be directly obtained from the MPEG-2 compressed video, but the object boundary is limited by macro-blocks rather than pixels. Also, the proposed method is proper for approximate object tracking rather than accurate tracing of an object because of limited information available in the compressed video data.

This study is mainly for the reduction of exposure dose by using a heavy elements filter(Gd) in the digital radiology. They contained heavy elements filter of Gd and X-ray beam hardening filters such as Al and Cu. According to the results of experimental evaluation, X-ray property was not changed with variety of kVp in the case of the Gd filter. The surface dose and absorption dose were increased in order of Cu and Al. The contrast of image showed the higher value in order of Cu, Al and Gd. While the use of Gd has increased the numerical value of the CR image, and grayscale has decreased noise value of the DR image.

『논어정의』의 『설문해자』(說文解字) 인용 연구

문수정,문준혜 서울대학교 인문학연구원 2018 人文論叢 Vol.75 No.2

Lunyuzhengyi (論語正義) by Liu Baonan (劉寶楠) is an annotated book that compiles the diverse achievements of previous annotations and a wide range of comments and achievements made by scholars. Comments were made on The Analects in the book called ZhengYi using the KaoZheng (考證) method, which interprets Confucian Classics based only on the evidence. It can be distinguishingly by the fact that it demonstrates an aggressive use of Shuowen Jiezi (說文解字), compared to other works. Specifically, Shuowen Jiezi is cited as the basis of the semantic commentary in the ZhengYi; as the basis upon which the main character (本 字) is distinguished from the temporary character (假借字), and as the basis for describing the original meaning (本義) and the derived meaning (引伸義). Most of the citations using Shuowen Jiezi are necessary in order to understand the contents; however, some contents that are supposed to be discussed mainly in the field of graphonomy are also included. This phenomenon is closely related to the recognition, starting from Dai Zhen (戴震) and extending through the Duan Yucai (段玉裁), that the ultimate principle (道) can be reached through a quest for the original meaning of each letter. This recognition brought encouragement to Shuowen Jiezi studies, which resulted in more attention being paid to verifying and explaining the meaning of the letters used in the texts of the annotations on various documents. Lunyuzhengyi (論語正義) demonstrates a propensity towards Shuowen Jiezi, which was a general tendency for the KaoZheng scholars of the Qing (淸) Dynasty, and it also became a characteristic of the Yangzhou School (揚州學派) which Liu Baonan was a member of. 유보남의 『논어정의』는 역대 주석서들의 다양한 성과를 흡수하고, 당시 학자들의 주석과 고증의 내용을 폭넓게 수용한 청대를 대표하는『논어』 주석서이다. 『논어정의』는 반드시 근거를 가지고 경전을 해석하는 고증학적 방법으로 『논어』를 주석했는데, 다른 주석서들보다 더 적극적으로 『설문해자』를 활용하였다는 점이 특징적이다. 구체적으로 『논어정의』에서는 『설문해자』를 인용하여 문자의 의미를 해설했고, 본자(本字)와 가차자(假借字)를 구분하고 본의(本義)와 인신의(引伸義)를 설명했다. 『설문해자』의 인용은 경전의 내용을 이해하기 위해 반드시 필요한 경우도 있지만, 일반적으로 문자 자체를 연구 대상으로 하는 문자학의 영역에서 논의되는 내용도 다수 보인다. 이것은 글자의 본래 의미 탐구와그것을 통해 경전이 담고 있는 궁극의 ‘도(道)’에 도달할 수 있다는 당시 학자들의 인식과 관계있어 보인다. 이러한 인식에 따라 청대에는 본의를 탐구한 『설문해자』가 활발하게 연구되었고, 각종 문헌에 대한 주석에서 경문에 쓰인 글자의 의미를 검증하고 설명하는 데 더 많은 주의를 기울이게 되었다. 이는 고증학자들의 일반적인 경향이지만, 유보남의 『논어정의』에서는 『설문해자』에 대한 편향성이 더 두드러지며, 유보남과 그를 포함한 건가시기 양주학파의 특징을 형성하였다.

Big Data Architecture Design for the Development of Hyper Live Map (HLM)

문수정,편무욱,배상원,이도림,한상원 한국측량학회 2016 한국측량학회지 Vol.34 No.2

The demand for spatial data service technologies is increasing lately with the development of realistic 3D spatial information services and ICT (Information and Communication Technology). Research is being conducted on the real-time provision of spatial data services through a variety of mobile and Web-based contents. Big data or cloud computing can be presented as alternatives to the construction of spatial data for the effective use of large volumes of data. In this paper, the process of building HLM (Hyper Live Map) using multi-source data to acquire stereo CCTV and other various data is presented and a big data service architecture design is proposed for the use of flexible and scalable cloud computing to handle big data created by users through such media as social network services and black boxes. The provision of spatial data services in real time using big data and cloud computing will enable us to implement navigation systems, vehicle augmented reality, real-time 3D spatial information, and single picture based positioning above the single GPS level using low-cost image-based position recognition technology in the future. Furthermore, Big Data and Cloud Computing are also used for data collection and provision in U-City and Smart-City environment as well, and the big data service architecture will provide users with information in real time.

How Environmental Activists Built a Media Agenda and Its Attributes: The Saemangeum Project in South Korea

문수정,심재철 한국사회과학협의회 2010 Korean Social Science Journal Vol.37 No.2

This study examines the press release as the beginning point of agenda‐building in the largest environmental conflict in the Republic of Korea: the Saemangeum project. The effects of the first and second - level agenda building were investigated through a content analysis of press releases and newspapers. The results showed that the number of press releases issued by environmental groups was positively associated with the amount of news coverage regarding the issue. Regarding the effects of the event, all newspapers, encompassing the liberal, neutral, and conservative, reported more stories about Saemangeum when the environmental groups planned and practiced various demonstrations. The results also revealed that the more demonstrations mentioned in the press releases, the more favorable the news coverage was found in the newspapers. In sum, this study found that a positive relationship existed between press releases and media coverage at the early triggering stage of agenda-building.
