곽미영,최진욱 대한의료정보학회 2005 Healthcare Informatics Research Vol.11 No.1

Objective: Electronic Medical Record contains the majority of clinical data in unstructured text. The information in the textual document can be stored in conceptual format and used to support clinical care by text summarization technique. In this study, we present Information Extraction(IE) using Concept Node(CN) which is extraction rule in case frame from brain radiology reports in SNUH(Seoul National University Hospital) for summarization. Method: Following steps are performed: design conceptual model to define semantic entities as extraction templates of brain radiology report, build CN dictionary based on statistical syntactic pattern and development of parser to extract relevant information based on defined templates. Results: The three evaluation results shows that 19% precision improvement after post processing supplemental specified complex verb construction and 19.24~21.25% accurate semantic effectiveness with extracting additional Korean noun. The average of precision is 85.18%, average of recall is 93.71% and F-measure is 0.89. Conclusion: Our approach has advantageous elements for different language at the same sentence. We expect this IE technology can summarize vast amount radiology texts material for clinical decision support system effectively and hope this study helps the evolution of clinical data representation in Korean medical records and its integration into the EMR in the future.

개구리밥 휴면구조 잠아의 구조적 특성

곽미영,김인선 韓國電子顯微鏡學會 2008 Applied microscopy Vol.38 No.4

일부 수생식물은 휴면구조로 엽상체가 변형된 잠아를 형성하여 적응 생존한다. 부유부엽성 식물인 개구리밥은 가을에 형성된 잠아로 동절기 물속에 가라앉아 휴면상태로 겨울을 난다. 이들 잠아는 엽상체의 특정 부위에서 기원하나 모엽상체와 달리 통기조직의 발달이 미흡하고 조직의 밀도가 높아 수중 침강에 유리한 구조로 분화된다. 잠아조직 내에는 일반적으로 기온상승 시생장재개에 바로 이용할 수 있는 영양분이 저장되어 있다. 이러한 특성을 지닌 개구리밥 잠아의 형성 및 발아에 대해서는 생리적, 생화학적으로 다양한 연구가 진행되고 있으나 잠아조직 세포의 미세구조 연구는 미흡한 상태이다. 이 연구에서는 엽상체와 잠아 엽육조직의 분화, 통기조직의 발달, 녹말의 분포, 세포수준에서의 미세구조 발달양상을 비교 연구하였다. 엽육조직이 비교적 분화되어 있는 모엽상체는 통기조직이 잘 발달되어 엽상체 용적의 약 37~45%를 차지하였다. 반면, 잠아는 엽육조직의 분화 없이 조직 내 통기조직의 발달이 미흡하여 전체 용적의 약 9~15%를 차지하였다. 모엽상체 엽육세포와 달리 잠아 세포내 세포질은 매우 치밀하며 엽록체 기질에는 녹말이 다량 축적되어 있다. 엽록체, 세포벽, 액포, 세포막은 모엽상체세포내 특성과 다른 양상으로 분화하였다. 이와 같이 잠아는 통기조직의 미흡한 발달, 세포질의 높은 밀도, 녹말의 다량 축적 등으로 조직의 밀도를 높게 하여 겨울철 휴면상태에 잘 적응된 구조로 발달시켜 축소된 개구리밥 식물체 생활사에 중요한 역할을 수행하는 독특한 구조로 분화하였다. 매우 빠른 생장으로 수면에 넓게 분포하는 개구리밥은 수생환경에 필요한 양분 및 빛을 차단하여 수생의 생태에 나쁜 영향을 미치기도 한다. 그러나 잠아형성 촉진 조건을 가해 주면 식물체는 쉽게 물속에 가라앉아 휴면상태를 유지할 수 있는 것으로 알려져 있다. 다른 식물 종들은 생장 및 형성 조건을 조절하기 어렵지만 개구리밥 식물체의 잠아는 이러한 구조적 특징으로 형성이 쉽게 조절될 수 있어 수생환경 개선에 유망한 후보가 되고있다. 향후 본 연구의 모엽상체와 잠아의 생장 및 구조 특성을 이용하여 유사 수생식물 잠아의 생장특성에 적용하면 수생환경 정화 등의 영역에서 유용하게 활용될 수 있는 휴면구조가 될 것이다. Hydrophytes such as Spirodela polyrhiza form dormant turions to withstand cold winters. The turion is an anatomically distinct structure from which a vegetative frond arises later during germination. The turions sink to the bottom of the pond when temperatures drop and remain there throughout the winter. In the spring, they float to the surface and germinate into a new frond from the turion primordium. Unlike fronds, turions are known to possess small aerenchyma, starch grains, and relatively dense cytoplasm. These features allow the turions to survive the cold winter season at the bottom of the pond. Spirodela polyrhiza has been investigated previously to a great extent, especially in its physiological, biochemical and ecological attributes. However, a little is known about the structural features of the frond and turion during turion development. Thus, the aim of the present study was to reveal the structural characteristics of the frond and turion with regard to tissue differentiation, aerenchyma development, starch distribution, and ultrastructure, with the use of electron microscopy. A moderate degree of mesophyll tissue differentiation was found in the frond, whereas the turion did not exhibit such differentiation. Within the frond tissue, approximately 37~45% of the cellular volume was occupied by a large aerenchyma, but only 9~15% was taken up by the aerenchyma in the turion. The turion cells, especially those of the turion primordium, were derived from frond cells, and contained cytoplasm. Their cytoplasm was densely packed with plastids, mitochondria, endoplasmic reticulum, Golgi bodies, and microtubules. Plasmodesmata were also well developed within these cells. The most striking feature observed was the distribution of starch grains within the plastids of turion cells. Before the turion sank to the bottom of the pond, a considerable amount of starch accumulated in the plastid stroma. The starch grains dissolved when temperatures rose in the spring, and this promptly provided the nutrients which the primordium needed for turion germination. The turion therefore, was an appropriate dormant structure for free-floating, reduced hydrophytes like Spirodela polyhriza due to its small aerenchyma and large starch grains that aided in the purpose of sinking below the surface of the water to survive cold winters. The new fronds that arose from such turions grew rapidly in the spring, beginning the new life cycle.

곽미영 21세기사회복지학회 2006 21세기사회복지연구 Vol.3 No.1

보육시설의 양적 증대는 사회적 요구와 가족의 시급한 당면과제의 해결이란 점에서 바람직한 방향이다. 그러나 보육시설의 통해 아동의 건전한 발달과 미래의 주역들의 잠재능력을 극대화한다는 관점에서 본다면, 질적인 면에서도 관심을 가져야 한다. 이를 위해 보육시설이 운영하는 프로그램의 질적 수준에 대한 체계적이고 지속적인 평가가 필요하다. 보육시설의 질적 수준을 높이고 사회적 책무성과 신뢰성을 확보하기 위해서는 보육시설을 종합적으로 평가 할 수 있는 평가인증제가 필요하다. 본 연구는 지금 실시되고「평가인증제」에 대한 국공립 보육시설 관계자의 인식을 파악하여 평가인증제 도입의 필요성을 위한 기초 자료를 제공하려는 데 목적이 있다. 또한「평가인증제」의 서울시 국공립 보육시설의 평가기준에 대한 타당도 증거를 제시함으로써 이 평가기준이 국공립보육시설의 자체평가 및 국가수준에서 국공립보육시설의 질적 수준을 평가할 수 있는 객관성과 타당성이 입증된 평가체제로 활용하기 위한 토대를 마련하고자 한다.

곽미영,정흥숙 한국의류학회 1995 한국의류학회지 Vol.19 No.2

The purpose of this study was to investigate a comparison between method of depaysement of Surrealism and modern costume. Surrealism was based on Freud's theory of unconsciousness and Hegelian dialectic. I found that its method of expression and inspiration have a continuous influence on a field of fashion through preceding study. Surrealism stimulated Elsa Schiaparelli (1890∼1973) to make creative and innovative costume which created a sensation the world of fashion in 1930. And it have been influence on modern fashion. From this point of view, I examined surrealistic painter of Rene´Magritte (1898∼1967) to use shocking method of depaysement through literature and photographes. And I made researches on Paris London collcetions from 1989 to 1994 in the cause of analysis a comparison with depaysement in painting of R. Magritte. As the result of analysising main works of R.Magritte according classification of Suzi Gabric (an art critic), he was expressive of usual object in various of depaysement. I also proved that modern fashion which was new shocking, innovative and avant-garde presented unconsciousness through these expression of depaysement with common subject. In consequence, the method of expression of surrealism have been a durable influence on modern costume.

Accessibility of Prenatal Care Can Affect Inequitable Health Outcomes of Pregnant Women Living in Obstetric Care Underserved Areas: a Nationwide Population-Based Study

곽미영,이승미,이태호,은상준,이진용,김윤 대한의학회 2019 Journal of Korean medical science Vol.34 No.1

Background: As of 2011, among 250 administrative districts in Korea, 54 districts did not have obstetrics and gynecology clinics or hospitals providing prenatal care and delivery services. The Korean government designated 38 regions among 54 districts as “Obstetric Care Underserved Areas (OCUA).” However, little is known there are any differences in pregnancy, prenatal care, and outcomes of women dwelling in OCUA compared to women in other areas. The purposes of this study were to compare the pregnancy related indicators (PRIs) and adequacy of prenatal care between OCUA region and non-OCUA region. Methods: Using National Health Insurance database in Korea from January 1, 2012 to December 31, 2014, we constructed the whole dataset of women who terminated pregnancy including delivery and abortion. We assessed incidence rate of 17 PRIs and adequacy of prenatal care. All indicators were compared between OCUA group and non-OCUA group. Results: The women dwelling in OCUA regions were more likely to get abortion (4.6% in OCUA vs. 3.6% in non-OCUA) and receive inadequate prenatal care (7.2% vs. 4.4%). Regarding abortion rate, there were significant regional differences in abortion rate. The highest abortion rate was 10.3% and the lowest region was 1.2%. Among 38 OCUA regions, 29 regions' abortion rates were higher than the national average of abortion rate (3.56%) and there were 10 regions in which abortion rates were higher than 7.0%. In addition, some PRIs such as acute pyelonephritis and transfusion in obstetric hemorrhage were more worse in OCUA regions compared to non-OCUA regions. Conclusion: PRIs are different according to the regions where women are living. The Korean government should make an effort reducing these gaps of obstetric cares between OCUA and non-OCUA.
