2019년 말 코로나가 처음 발생한 이후 이와 관련한 새로운 어휘들이 1,500개가 넘어설 정도로 독일어에 지대한 영향을 끼치고 있으며, 최근에 국내에서도 코로나 신어 관련 학술서가 발간되어 코로나 사태가 범 세계적으로 직면하고 있는 주요 문제임을 증명하고 있다. 독일어 Virus는 라틴어에 기원을 두고 있으며 1968년에 발견된 바이러스의 형태가 전자현미경으로 관찰하면 왕관형태로 나타나서 ‘화관’ 또는 ‘왕관’을 의미하는 라틴어 corona에 따라 코로나바이러스로 명명되었다. 독일어 Virus는 라틴어에서는 중성명사이지만 두덴 온라인 사전에는 ‘중성’과 ‘남성’으로 표시되었으며, 독일 일상어에서는 -us로 끝나는 명사는 주로 남성명사이기 때문에 남성명사로도 사용되고 있다. ‘코로나바이러스 신어’란 코로나19 발생이후 새로 생겨난 어휘 또는 새로운 의미가 추가된 어휘뿐만 아니라 코로나19 이전에 이미 사용된 어휘라도 코로나 이후 사용 빈도수가 두드러지게 증가하였거나 특정 학술 영역에서 제한적으로 사용되다가 일상어에까지 영향을 끼친 어휘라고 정의할 수 있겠다. 본 연구에서는 구글 검색에서 사용 빈도수가 높게 나타난 코로나바이러스 신어들을 중심으로 ‘신조어’, ‘새의미’, 축약어‘, ’혼성어‘ 등을 형태와 의미론적 관점에서 분석 및 기술하고 그 어휘들을 바탕으로 학습자들의 관심과 흥미를 유발할 수 있는 ‘음절’, ‘어휘’, ‘그림’, ‘연상작용’ 등을 활용한 다양한 교수학적 어휘학습 모델이 제시되었다. Seitdem Corona Ende des Jahres 2019 zum ersten Mal ausgebrochen ist, sind über 1.500 neue Wörter in Bezug darauf entstanden, so dass sie einen erheblichen Einfluss auf das Gegenwartsdeutsch ausüben. Das Wort Virus stammt aus dem Lateinischen und das 1968 neu gefundene Virus wurde als Coronavirus deswegen bezeichnet, weil es bei der Beobachtung durch das Elektronenmikroskop wie ein „Kranz“ bzw. „Krone“ (lat. corona) aussah. In der vorliegenden Arbeit werden unter Corona-Neologismen sowohl die Wörter verstanden, die seit dem Ausbruch von COVID-19 neu entstanden sind bzw. neue Bedeutungen erhalten haben, als auch die, die zwar schon davor verwendet bzw. nur in bestimmten Fachbereichen gebraucht wurden, aber seitdem hohe Frequenzzahlen erreicht haben bzw. in die Alltagssprache eingedrungen sind. Die Wörter, die bei Frequenzuntersuchungen in Google höhere Häufigkeiten aufweisen, sind zunächst unter morphologisch-semantischen Gesichtspunkten wie z. B. ‘Neuprägung’, ‘Neubedeutung’, ‘Abkürzung’, ‘Kontamination’ sowie nach Themenbereichen analysiert und dargestellt worden. Im Anschluss daran sind verschiedene Wortschatz-Lehrpläne anhand Kriterien wie z. B. ‘Silben’, ‘Wörtern’, ‘Bildern’, ‘Assoziationen’ usw. vorgeschlagen worden.
Development and Effectiveness Analysis of Bucket Design for Para Ice Hockey Players
Wanho Jang,Jongbae Kim 한국HCI학회 2018 한국HCI학회 학술대회 Vol.2018 No.1
The purpose of this study is to develop a bucket design for two para ice hockey players. In the development of the bucket, the needs of the target were derived through consultation. We used a scanner to shape the body in order to develop a bucket suitable for the body. The bucket was designed using a 3D modeling software. K-QUEST 2.0 was used to evaluate the satisfaction of the developed bucket. Overall, the scores of buckets and bucket service were marked high. Future studies should be undertaken to supplement the bucket design.

The fuel and spark control of gasoline engines at cold idle is a dominant factor to meet the exhaust emission regulations being reinforced recently. The engine control of cold idle phase has to be optimized to get low emissions enough to meet the regulations and good stability customers are satisfied with. In this study, we improved engine stability and reduced exhaust emissions by optimizing cold idle cam phasing after engine start.

The apoptosis of macrophages occurs throughout all stages of atherosclerosis. It is known to constitute atheromatous plaque, increase plaque instability, and thus contribute to the development of atherosclerosis. However, there still remains much to be elucidated on how the apoptotic macrophages affect the endothelial cells and also how they contribute to the development of atherosclerosis. Here we present a microfluidic system, which enables co-culture of apoptotic macrophages and endothelial cells in fibrin gel that mimics in vivo extracellular matrix. With the system, we can investigate the effect of macrophage apoptosis on vascular endothelial cells by quantitatively analyzing the level of reactive oxygen species of HUVECs, integrity of VE-cadherin and cell proliferation. We expect that this system could be utilized further for understanding different mechanisms of apoptotic macrophage on the development of atherosclerosis.
Dynamical Motion Driven by Periodic Forcing on an Open Elastic Tube in Fluid
Lee, Wanho,Lim, Sookkyung,Jung, Eunok Global Science Press 2012 Communications in computational physics Vol.12 No.2
<B>Abstract</B><P>We present a three dimensional model of an open elastic tube immersed in fluid to understand valveless pumping mechanism. A fluid-tube interaction problem is simulated by the volume conserved immersed boundary method which prevents the generation of spurious velocity field near the tube and local cluster of the tube surface. In order to explain pumping phenomena without valves, average net flow is measured by changing parameter values such as pumping frequency, compression duration, and pumping amplitude. Some frequencies that make the system reach maximal or minimal net flow are selected to study case by case. We also study the effectiveness of fluid mixing using the Shannon entropy increase rate.</P>

<P>A mathematical and computational model combining the heart and circulatory system has been developed to understand the hemodynamics of circulation under normal conditions and ventricular septal defect (VSD). The immersed boundary method has been introduced to describe the interaction between the moving two-dimensional heart and intracardiac blood flow. The whole-heart model is governed by the Navier-Stokes system; this system is combined with a multi-compartment model of circulation using pressure-flow relations and the linearity of the discretized Navier-Stokes system. We investigate the velocity field, flowmeters, and pressure-volume loop in both normal and VSD cases. Simulation results show qualitatively good agreements with others found in the literature. This model, combining the heart and circulation, is useful for understanding the complex, hemodynamic mechanisms involved in normal circulation and cardiac diseases.</P>
Axial Green Function Method for Axisymmetric Electromagnetic Field Computation
Lee, Wanho,Kim, Hong-Kyu,Kim, Do Wan IEEE 2017 IEEE transactions on magnetics Vol.53 No.6
<P>Only with 1-D Green function for 1-D elliptic differential operator, we can solve 2-D/3-D general elliptic problems by applying the axial Green function method (AGM). An extension of AGM is proposed to enforce Neumann boundary conditions. This extension is directly available for 2-D problems with straight boundaries parallel to axes on which Neumann boundary conditions are assigned. It is thoroughly attributed to the specific axial Green functions associated with the Neumann conditions. Moreover, since this extended AGM (XAGM) in 1-D satisfies the transmission condition across an interface along which the permittivity is discontinuous, it can be applied to 2-D problems with interfaces parallel to axes without loss of accuracy. Finally, we apply the XAGM in 2-D to 3-D axisymmetric electric potential problems with variable and/or even discontinuous permittivities along interfaces. Owing to the cylindrical coordinate transform, the transformed problem is tractable to solve using this XAGM. Arbitrary distribution of axial lines is available, which must be a marked advantage of XAGM compared to other methods.</P>
