이현아,조윤희,조윤숙,한현주,이주연,정근화,이상건,Lee, Hyeon-Ah,Jo, Yun Hee,Cho, Yoonsook,Hahn, Hyeon Joo,Lee, Ju-Yeun,Jung, Keun-Hwa,Lee, Sang Kun 한국임상약학회 2017 한국임상약학회지 Vol.27 No.1
Objective: The perioperative management of antithrombotic therapy is often challenging and it requires a fine balance between the risk of hemorrhage and thrombosis. We aimed to evaluate the antithrombotic management for moderate to high risk patients in real world setting. Methods: Among the patients who were consulted to the neurologist for the evaluation of perioperative risk from 2010 to 2012, patients undergoing moderate to high risk surgery and taking antithrombotics within 30 days were identified. We analyzed the timing of discontinuation and reinitiation of antithrombotic drugs before or after surgery as well as the status of bridging therapy. In addition, the conformity with the guideline suggested by American College of Chest Physicians was assessed. The rate of thromboembolic event and major hemorrhage were also investigated. Results: A total of 329 patients were included. The concordance rate of warfarin stop and restart time with guideline was 23.4% and 10.3%, respectively. Continuing aspirin in patients undergoing coronary artery bypass surgery or non-cardiac surgery in patients with high risk for cardiovascular events were 59.2% and 2.6%, respectively. Bridging therapy was adopted in 92.9% and 81.2% in patients who had received anticoagulant before surgery and who were at high and low risk thromboembolism, respectively. In entire cohorts, 30-day incidence of major bleeding and thromboembolic event were 31.9% and 3.0%. Co-morbid renal disease were shown as independent predictor for major bleeding (adjusted OR 2.65. 95% CI 1.33-5.28). Conclusion: The concordance rate with guideline regarding perioperative antithrombotic use was low and bridging therapy was prevalent in patients undergoing moderate to high risk surgery.

홍삼 성분의 혈당강하작용 연구 (I) :쥐의 배양 간세포의 당대사 관련 효소 활성에 미치는 홍삼 사포닌 성분의 영향 조사
이현아,권상옥,이희봉,Lee, Hyeon-A,Gwon, Sang-Ok,Lee, Hui-Bong 고려인삼학회 1997 Journal of Ginseng Research Vol.21 No.3
In this study, rat hepatocytes known to have active carbohydrate metabolism were obtained by using the liver perfusion technique to examine the hypoglycemic action of red ginseng saponin components [ginsenoside (mixture, $Rb_1$, and $Rg_1$)] and incubated in two different media-one containing insulin and glucagon (control group), and the other containing glucagon only, The specific activities of some regulatory enzymes such as glucokinase, glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and glucose 6-phosphatase, in main pathways which were directly related to the glucose metabolism were compared between these two kinds of hepatocytes cultured in two different media. The effects of red ginseng saponin components [ginsenoside (mixture, $Rb_1$, and $Rg_1$)] under the concentration of $10^3$~$10^6$% on these enzymes In hepatocytes were also investigated, when they were added to these two media. The results were as follows. The specific activity of enzymes such as glucokinase, glucose 6-phosphate dehydrogenase, and 6-phosphogluconate dehydrogenase related to glucose-consuming pathways of insulin-deficient group was much less than control one, however, their decreased activity was recovered after the addition of ginseng components at all range of concentrations. The increased specific activity of these on - zymes was shown by the addition of ginseng components to the control group. On the other hand, the specific activity of glucose 6-phosphatase related to glucose-producing pathway of insulin-deficient group was much higher than control one, but their Increased activity was decreased after the addition of ginseng components at all range of concentrations. The same results were obtained after the addition of ginseng components to the control group. These results suggest that the red ginseng saponin components might better diabetic hyperglycemia by regulating the activity of enzymes related to glucose metabolism directly and/or Indirectly though more detailed studies were needed.

지금까지 시공간 객체를 다양한 관점에서 접근하여 표현하려는 많은 연구가 이루어졌다. 이 대부분의 연구는 GIS적 관점과 시간 데이터베이스 관점, 그리고 객체 지향적 관점 및 데이터타입 접근 방법으로 시공간 객체를 표현하고 있다. 시공간 객체는 공간 속성이 불연속적으로 변하는 객체, 위치 정보가 연속적으로 변하는 객체, 그리고 면적과 위치가 연속적으로 변하는 객체로 분류된다. 그러나 기존의 시공간 모델들은 한 종류의 객체에만 초점을 맞추고 있다. 따라서 이 논문에서는 유클리드 평면상에서 세가지 형태의 객체를 모두 표현할 수 있는 시공간 객체 모델을 제안한다. 이를 위해 유효시간 개념을 확장한 시간 모델과 함께 객체의 연속된 두 버전간의 관계성을 정의하여 이동 객체와 이력 객체 모두를 표현하는 방식을 사용한다. 여기서 제안하는 2차원 시공간 객체 모델은 개방형 GIS 명세서에서 제시하고 있는 2차원 공간 객체 모델을 따름으로써 표준 공간 모델과의 호환성을 보장한다. Most of works have been performed on representation of spatiotemporal objects from various points of view. Most of them represent spatiotemporal objects using approaches from GIS, temporal databases, object-oriented databases or data type. Spatiotemporal objects can be classified as objects whose position and shape changes discretely over time, objects whose position changes continuously and objects whose shape changes continuously as well as position. Previous works on spatiotemporal model have focused on only one of them. In this paper, we propose a spatiotemporal model that can represent three types of objects in Euclidean plan. For this purpose, we represent both discrete and continuous moving objects by defining temporal model extended from valid time and by defining relationship between two consecutive versions of objects. The proposed spatiotemporal object model is based on open GIS specification so that it has compatibility with existing spatial data model.

창의 융합적 역량 향상을 위한 디자인 사고과정 수업에 대한 연구
이현아(Hyeon A Lee),박유신(Yoo Shin Park) 한국미술교육학회 2016 美術敎育論叢 Vol.30 No.2
본 연구는 디자인 사고 과정의 적용을 통해 창의·융합 역량을 강화하기 위한 수업모형에 대한 연구이다. 창의·융합 역량은 2015 개정 교육과정에서 미술과의 핵심 역량으로 강조되고 있다. 디자인 사고과정은 다양한 분야를 가로질러 통합한다는 점에서 융합적 사고 능력을 기르는데 도움을 줄 수 있으며, 디자인 사고과정에서 문제를 해결하기 위한 창조적인 아이디어의 발상은 창의·융합 역량을 키우는 데에 기여할 수 있다. 본 연구에서는 이를 위한 방안으로 디자인 사고과정을 고찰하였다. 그 중 대표적인 디자인 사고과정 수업 모델을 살펴보고 이 모델에 기반 하여 초등학교 학생을 대상으로 한 수업을 설계하고 실행하였다. 디자인 사고 과정을 적용한 수업을 통해 다음과 같은 몇 가지 결론과 시사점을 얻을 수 있었다. 첫째, 학생들은 디자인 사고과정을 거치면서 창의적 사고가 신장된 모습을 보여주었다. 둘째, 학생들은 디자인 사고과정을 통해 융합적인 사고를 활성화 시킬 수 있었다. 셋째, 학생들은 디자인 사고과정을 거치면서 ‘디자인이란 무엇인가’에 대한 메타적 성찰을 거쳤고, 유의미한 사고 변화를 얻었다. 디자인 사고 과정에 기반한 다양한 수업설계연구 및 적용은 앞으로 창의적 사고를 통해 융합적으로 문제해결을 하는 21세기 역량 강화에 많은 도움이 될 것으로 생각된다. This study investigates learning models which develop creative and convergence competency through the application of the design thinking process. Creative and convergence competency was emphasized by the 2015 Revision of the Korean National Curriculum as the core competency of Korea’s art curriculum. Convergence competency can be developed by the design thinking process(iDESIGN), as the process involves finding a solution by combining a variety of possible answers. Design thinking process(iDESIGN) can also contribute to the development of creative competency through the formation of creative and original solutions to problems. This study examined the DK-12 education program in the United States, which adopts design thinking, and learning models. The study found the following conclusions and implications through the design and execution of this lesson, which implemented design thinking. Firstly, students developed problem solving skills through the design thinking process. Secondly, it was shown that through this process, students also developed creative and convergence competency. Thirdly, students created a esthetic value through the internalization of virtues and values. This study suggests that studies on, and applications of, learning models based on the design thinking process will assist future cultivations of the ability to solve problems through convergent and creative thought processes.

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a lowgrade B-cell lymphoma that typically follows an indolent clinical course. It occurs in a variety of mucosal linings extranodal tissue, most commonly in the stomach. Other commonly involved sites include other parts of the gastrointestinal tract, thyroid, salivary gland, lung, lacrimal gland, synovium, dura mater, breast, skin, and eyes. It occurs very rarely in the buccal mucosa. A 50-year-old man came to the clinic while presenting a 5-month history of rightsided buccal mass. The incisional biopsy did not confirm the diagnosis of the lesion. He underwent complete excision of buccal mass for the diagnosis and treatment. The final pathology confirmed MALT lymphoma immunohistochemically. After surgery, he received radiotherapy with 30.6 Gy. There is no recurrence for 8 months after treatment. Herein we report a rare case of buccal MALT lymphoma with a review of the literature.
