The objective of this study was to evaluate the flood control capacity of the agricultural reservoir based on state-of-the-art climate change scenario - SSP (Shared Socioeconomic Pathways). 18 agricultural reservoirs were selected as the study sites, and future rainfall data based on SSP scenario provided by CMIP6 (Coupled Model Intercomparison Project 6) was applied to analyze the impact of climate change. The frequency analysis module, the rainfallrunoff module, the reservoir operation module, and their linkage system were built and applied to simulate probable rainfall, maximum inflow, maximum outflow, and maximum water level of the reservoirs. And the maximum values were compared with the design values, such as design flood of reservoirs, design flood of direct downstream, and top of dam elevation, respectively. According to whether or not the maximum values exceed each design value, cases were divided into eight categories; I-O-H, I-O, I-H, I, O-H, O, H, X. Probable rainfall (200-yr frequency, 12-h duration) for observed data (1973∼2020) was a maximum of 445.2 mm and increased to 619.1∼1,359.7 mm in the future (2011∼2100). For the present, 61.1% of the reservoirs corresponded to I-O, which means the reservoirs have sufficient capacity to discharge large inflow; however, there is a risk of overflowing downstream due to excessive outflow. For the future, six reservoirs (Idong, Baekgok, Yedang, Tapjung, Naju, Jangsung) were changed from I-O to I-O-H, which means inflow increases beyond the discharge capacity due to climate change, and there is a risk of collapse due to dam overflow.

Purpose The Coronavirus disease 2019(COVID-19) pandemic is spreading rapidly around the world. Infection control measures, which are wearing a mask, hand washing, and alcohol-based disinfectants, are being taken to control the COVID-19. We attempted to compare the incidence of pneumonia in the pre-COVID-19 and during COVID-19 endemic. Methods We conducted a single-center, retrospective study for patients hospitalized to the respiratory department in Soonchunhyang Cheonan hospital from January 2019 to December 2020. It was divided into January to December 2019 as pre-COVID-19 and January to December 2021 as COVID-19 endemic. We investigated patients with pneumonia who were admitted through emergency room. Results In total, 2,144 patients were hospitalized during the study period. The number of all patients from Emergency department decreased from 1,259 in the pre-COVID-19 to 885 during COVID-19 endemic. Of 2,144 patients, patients with pneumonia was decreased from 1,001(79.5%) to 651(73.6%) (P=0.001). In the patients with pneumonia transferred from other hospitals, including local secondary hospital, geriatric hospital, and long-term care facilities, there was no difference of pneumonia (180(88.2%) vs. 156(86.7%), P=0.643), while there was a significant difference in the patients admitted from the community (821(77.8%) vs. 495(70.2%), P<0.001). Meanwhile, patients admitted to the intensive care unit was significantly increased from 216(17.2%) to 234(26.4%)(P=<0.001). Conclusions The incidence of community acquired pneumonia decreased during the COVID-19 endemic, but the severity of pneumonia increased.

Rollable Microfluidic Systems with Microscale Bending Radius and Tuning of Device Function with Reconfigurable 3D Channel Geometry

Kim, Jihye,You, Jae Bem,Nam, Sung Min,Seo, Sumin,Im, Sung Gap,Lee, Wonhee American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.12

<P>Flexible microfluidic system is an essential component of wearable biosensors to handle body fluids. A parylene-based, thin-film microfluidic system is developed to achieve flexible microfluidics with microscale bending radius. A new molding and bonding technique is developed for parylene microchannel fabrication. Bonding with nanoadhesive layers deposited by initiated chemical vapor deposition (iCVD) enables the construction of microfluidic channels with short fabrication time and high bonding strength. The high mechanical strength of parylene allows less channel deformation from the internal pressure for the thin-film parylene channel than bulk PDMS channel. At the same time, negligible channel sagging or collapse is observed during channel bending, down to a few hundreds of micrometers due to stress relaxation by prestretch structure. The flexible parylene channels are also developed into a rollable microfluidic system. In a rollable microfluidics format, 2D parylene channels can be rolled around a capillary tubing working as inlets to minimize the device footprint. In addition, we show that creating reconfigurable 3D channel geometry with microscale bending radius can lead to tunable device function: tunable Dean-flow mixer is demonstrated using reconfigurable microscale 3D curved channel. Flexible parylene microfluidics with microscale bending radius is expected to provide an important breakthrough for many fields including wearable biosensors and tunable 3D microfluidics.</P>

Choi, Jihye,Lee, Hyeonseung,Jung, Beomsic,Woo, Jeong-Hyun,Kim, Ju-Young,Lee, Kyu-Sung,Jeong, Jeung-hyun,Choi, Jea-Young,Kim, Won Mok,Lee, Wook Seong,Jeong, Doo Seok,Lee, Taek-Sung,Choi, Doo Jin,Kim, I IOP 2018 Journal of Physics. D, Applied Physics Vol.51 No.27

<P>This paper reports the fabrication of crystalline silicon passivated emitter rear totally diffused (c-Si PERT) solar cells with ultra-thin p-type wafers 50 <I>µ</I>m in thickness. Co-diffusion of boron and phosphorus in a single rapid thermal processing cycle, and an Al spin-on glass post-curing process were developed to remove the boron rich layer which is detrimental to c-Si solar cells. Co-diffusion was carried out with spin-on diffusion sources using boric acid and a P spin on dopant for simple and cost-effective emitter and back surface field (BSF) formation processes. The fabricated ultra-thin c-Si PERT cell featured an open circuit voltage (V<SUB>oc</SUB>) of 0.575 V, a short circuit current density (J<SUB>sc</SUB>) of 35.8 mA cm<SUP>−2</SUP>, a fill factor of 0.725, and a power conversion efficiency of 15.0%. The efficiency has improved by 2% compared with the standard structure cell with Al-BSF using thin evaporated Al 2 <I>µ</I>m in thickness. Along with cell output parameters, the flexural strength and critical bending radius were measured by a four point bending test, and the results showed that the solar cells with thinner rear Al electrodes are more applicable for a flexible solar cell device.</P>

독일어 뉘앙스첨사에 관한 예비교사들의 인식 연구

성지혜 ( Sung Jihye ) 한국독일어문학회 2019 독일어문학 Vol.86 No.-

첨사는 독일어의 두드러진 특징 중 하나이다. 그 중에서도 화용론적 기능이 가장 잘 드러나는 뉘앙스첨사는 구어체에서 원활한 의사소통을 가능하게 하는 언어적 수단이다. 뉘앙스첨사는 독일어 내에서도 다른 단어로 대체가 불가능하며 느낌으로 이해되기 때문에 외국인 학습자들은 뉘앙스첨사의 의미와 기능을 정확하게 이해하는 데 많은 어려움은 겪는다. 따라서 독일어 교수·학습 과정에서 뉘앙스첨사가 명시적으로 다루어질 필요가 있다. 본 연구에서는 뉘앙스첨사의 기능과 유형, 현행 고등학교 독일어 교과서에서 뉘앙스첨사의 제시 현황을 분석한다. 이를 토대로 교수·학습과정 지도안 작성과 대화문의 우리말 번역을 통해서 뉘앙스첨사에 관한 예비교사들의 인식을 살펴본다. 뉘앙스첨사는 문장 내용에 대한 화자의 입장을 나타낼 뿐만 아니라 발화수반, 담화조정, 텍스트연결 등 의사소통상황에서 다양한 기능을 수행한다. 현행 고등학교 독일어 교과서는 뉘앙스첨사를 명시적으로 다루고 있지는 않으며, denn, doch, mal, ja와 같이 제한된 수의 뉘앙스첨사를 대화문의 일부로 제시하고 있는 수준이다. 예비교사들은 어휘 수준에서 뉘앙스첨사의 의미를 어느 정도 인지하고 있었지만 모든 예비교사들이 교수·학습과정 지도안에 뉘앙스첨사의 의미와 기능에 대한 내용을 반영한 것은 아니었다. Partikeln zählen zu den hervorstehenden Merkmalen des Deutschen. Vor allem Abtönungspartikeln sind unverzichtbar fur die Naturlichkeit der Kommunikation in der gesprochenen Sprache. Fur Deutschlernende stellen Partikeln oft eine große Hurde dar, weil ihre Bedeutung komplex ausgesprochen ist und sich nicht einfach durch ein Wort ubersetzen lässt. Deutschlerher/innen brauchen folglich sowohl didaktisches als auch linguitisches Expertenwissen, um garantieren zu können, dass Patikeln zielspachlich gelernt werden. Die vorliegende Studie analysierte, wie koreanische Schulbucher fur das Fach Deutsch die Abtönungspartikeln behandeln. Außerdem wurde mit Hilfe von Befragungen sowie einer Durchsicht von Unterrichtsplänen das entsprechende Wissen der koreanischen Deutschlehrer/innen ermittelt. Die Ergebnisse lassen sich wie folgt zusammenfassen: Abtönungspartikeln drucken bekanntlich etwas uber die Stellung des Sprechers zum Satzinhalt aus und sie haben textverknupfende sowie expressive Funktionen. Die koreanischen Schulbucher versäumen es, diese Charakteristik explizit zu machen. Daruber hinaus beschränken sie sich auf ein relativ kleines Inventar von Abtönungspartikeln. Was die Lehrenden betrifft, so lässt sich festhalten, dass diese typischerweise uber das notwendige linguisische Wissen verfugen. Allerdings spiegelt sich das in den Unterrichtsplänen kaum wider, wo Abtönungspartikeln höchstens oberflächlich eine Rolle spielen.

속담 및 명언을 활용한 독일어 교수ㆍ학습 모형

성지혜 ( Sung Jihye ),허남영 ( Heo Namyoung ) 한국독일어문학회 2020 독일어문학 Vol.91 No.-

본 연구에서는 속담 및 명언을 활용해 독일어 교수ㆍ학습 모형을 구안하고자 한다. 외국어교육에서 속담 및 명언은 목표 국가의 언어적, 문화적 요소를 동시에 학습할 수 있는 중요한 자료이다. 무엇보다 중, 고급수준의 학습자가 다양하고 수준 높은 어휘와 표현으로 외국어를 사용하고자 할 때, 단순한 구문의 기계적인 반복 연습만이 해답이 될 수 없기 때문이다. 이때 속담 및 명언은 언어적, 문화적 요소를 동시에 가진 자료로 수준 높은 어휘와 표현을 구사하는 데 긍정적인 요소가 될 수 있다. 구체적으로 수업설계의 방향은 ‘주제별 독일어 속담 및 명언 이해, 작문·읽기를 통한 구문 연습, 독일 문화 읽기’의 순서로 진행된다. 먼저, 속담 및 명언을 주제별로 분류한 후, 속담 및 명언에 포함된 독일어 구문을 별도로 제시한다. 그다음으로 작문·읽기 연습을 통해 구문이 학습될 수 있도록 활동을 구성한다. 마지막으로 주제와 관련된 읽을거리를 제시하여 문화 학습으로 내용을 확장한다. 지금까지 실제 수업에서 속담 및 명언을 활용하여 그 유용성을 검증하고 교수ㆍ학습을 위한 실제적인 방안을 논의한 사례는 미비하였다. 그 내용과 접근방식이 속담 및 명언을 구문론적으로 분석하여 전달하거나 문화 학습을 위한 자료로 사용되는 수준에 그쳤다. 이러한 상황에서 속담 및 명언을 교수ㆍ학습 자료로서 어떻게 활용할 것인가에 대한 방법적 측면의 논의는 가치가 있다고 할 것이다. Im Fremdsprachenunterricht sind Sprichwörter und Sprüche ein wichtiges Mittel, mit dem Lernende sprachliche und kulturelle Elemente des Ziellandes gleichzeitig lernen können. Aber wenn Fortgeschrittene eine Fremdsprache mit verschiedenen und hochwertigen Vokabeln und Ausdrücken verwenden möchten, können nur einfache mechanische Wiederholungsübungen nicht die Antwort sein. In diesem Fall können Sprichwörter und Sprüche ein positiver Faktor sein. In dieser Studie soll daher ein deutsches Lehr- und Lernmodell erstellt werden. Die Richtung der Unterrichtsplan ist 1) Sprichwörter und Sprüche thematisch zu verstehen 2) Syntax durch Schreiben und Lesen zu üben 3) Texte über deutsche Kultur zu lesen Bisher gab es unzureichende Diskussionen über Methoden zum Lehren und Lernen und zur Überprüfung der Nützlichkeit von Sprichwörtern und Sprüchen im tatsächlichen Unterricht. Sein Inhalt und sein Ansatz beschränken sich auf die Ebene der syntaktischen Analyse und Bereitstellung von Sprichwörtern und Sprüchen oder werden als Mittel zum kulturellen Lernen verwendet. In dieser Situation lohnt es sich zu diskutieren, wie Sprichwörter und Sprüche als Mittel zum Lehren und Lernen verwendet werden können.

Kim, Jihye,Park, Minjung,Sung, Angela Dong-Min,Kim, Kyeong Han,Sung, Soo-Hyun KOREAN PHARMACOPUNCTURE INSTITUTE 2020 Journal of pharmacopuncture Vol.23 No.4

Objectives: Chronic diseases (CDs) continue to increase due to advances in medicine and increase in lifespan, affecting quality of life and resulting in economic loss through treatment costs. This study addressed the perception characteristics of the effectiveness of Korean medicine (KM) based on the existence of a CD to determine the national preference for KM treatment. Methods: Using data from the 2017 National Survey of KM Usage, we evaluated the perception on treatment effect of 16 diseases by dividing them into the CD group and the non-CD group. Response reliability was verified by applying the chi-square test (χ2-test) analysis method of the Statistical Package for the Social Sciences (SPSS) statistical program. Results: The analysis of the perception on effectiveness of KM for patients with CD (n = 1,050, 21.0%) and for patients with non-CD (n = 3,950, 79.0%) showed an overall similar trend for all the 16 diseases. The response rates of having some treatment effect were high for nine diseases namely, disc-related disease (CD: 70.7%, non-CD: 73.1%), osteoarthritis (CD: 72.3%, non-CD: 72.4%), frozen shoulder and shoulder pain (CD: 79.6%, non-CD: 81.4%), back pain (CD: 84.6%, non-CD: 85.0%), sprain (CD: 84.8%, non-CD: 84.1%), facial nerve paralysis (CD: 73.5%, non-CD: 71.7%), stroke (CD: 66.2%, non-CD: 62.8%), digestive disease (CD: 53.3%, non-CD: 50.0%), and common cold and rhinitis (CD: 44.7%, non-CD: 44.8%). Conclusion: The present results found that there was little difference in the perception on effectiveness of KM for each of the 16 diseases in patients with CD and non-CD, however, 70% or more of the respondents recognized some treatment effect on musculoskeletal disorders, regardless of the existence of CD. Preferential political support for KM treatment of chronic musculoskeletal disorders is recommended.

The Animal and Plant Quarantine Agency conducts a targeted sampling plan and analysis for veterinary drugs within the country every year. Target compounds included tetrachlorvinphos as an organophosphate, diminazene as an anti-infective medication, ketoprofen as a nonsteroidal anti-inflammatory drug, triclabendazole and clorsulon as flukicides in 2022. These compounds were not included in National Residues Program (NRP), despite their high sales ranking. A total of 94 bovine muscle samples and 20 equine muscle samples were collected from various locations across the country. The analysis of target compounds in muscle was performed using LC-MS/MS coupled with Food code 8.3.1 revised in 2022. A 2 g sample of muscle tissue was extracted using a water: acetonitrile (1:4, v/v) solution, then cleaned up with C18 and hexane saturated with acetonitrile. Compounds were separated with C18 column and mobile phases consisted of 0.1% formic acid in water (A) and 0.1% formic acid in acetonitrile (B). All analytes exhibited good linearity with correlation coefficients (R2) higher than 0.992. The limit of quantification (LOQ) of these compounds ranged from 0.21 to 2.79 μg/kg except for diminazene (3.85~6.86 μg/kg). The average recoveries of these analytes were 89.45~129.13% in muscle at spiked level of 10 or 20 μg/kg. Relative standard deviations (%) (intra-day and inter-day) were lower than 20% for all target compounds, except for diminazene and triclabendazole, whose intra-day RSD % was slightly higher than 20% in equine muscle. Testing confirmed that all 94 bovine and 20 equine muscle samples from 9 provinces were free from residues of veterinary drugs. Monitoring of compounds not included in the NRP should continue to ensure consumer health and food safety.

Grape seed proanthocyanidin extract ameliorates murine autoimmune arthritis through regulation of TLR4/MyD88/NF-κB signaling pathway

( Sang-hyon Kim ),( Jihye Bang ),( Chang-nam Son ),( Won-ki Baek ),( Ji-min Kim ) 대한내과학회 2018 The Korean Journal of Internal Medicine Vol.33 No.3

Background/Aims: Grape seed proanthocyanidin extract (GSPE) has been reported to have a beneficial effect on regulating inf lammation. However, the anti-inflammatory mechanism of GSPE remains unclear. The aim of this study was to verify the influence of GSPE on the Toll-like receptor 4 (TLR4)-mediated signaling pathway in the regulation of murine autoimmune arthritis. Methods: Collagen-induced arthritis (CIA) was induced in dilute brown non-agouti (DBA)/1J mice. The mice were treated with GSPE (0 or 100 mg/kg) intraperitoneally. The severity of arthritis was assessed clinically, biochemically, and histologically. Immunostaining for TLR4 was performed. The expressions of TLR4 and downstream signaling molecules were analyzed by Western blot. The effect of GSPE on lipopolysaccharide (LPS)-induced TLR4 activation was also evaluated using RAW264.7 cells and fibroblast-like synoviocytes (FLSs) from patients with rheumatoid arthritis and from those with osteoarthritis. Results: GSPE attenuated the clinical severity of arthritis and decreased histological damage. GSPE treatment reduced the number of TLR4-stained cells in the synovium of mice with CIA. GSPE also downregulated the expression of TLR4, myeloid differentiation factor 88 (MyD88) and phosphorylated IκBα synovial protein in CIA mice. Concurrently, GSPE inhibited the nuclear translocation of nuclear factor-κB (NF-κB) subunits (p65 and p50). LPS-induced TLR4 activation was suppressed by GSPE in human FLS as well as in murine macrophages in vitro. Conclusions: Our results demonstrated that GSPE ameliorated CIA by regulating the TLR4-MyD88-NF-κB signaling pathway.
