치차로스의 <시적인 순간> 중 ‘철새’, ‘블루스 왈츠’, ‘나비 래그타임’, ‘서부기차’ 분석 및 교수법적 제안

신은혜 ( Shin¸ Eun-hyeㆍlee¸ Joo-hye ),이주혜 한국피아노교수법학회 2021 음악교수법연구 Vol.22 No.1

치차로스(Christos Tsitsaros, b. 1961)는 미국 일리노이 대학교의 피아노 교수학과 교수이며, 피아노 교육용 작품을 많이 작곡하였다. 본 논문은 국내에 잘 알려지지 않은 그의 작품에 대한 정보를 제공하고 한정된 레퍼토리의 선택지를 넓히는데 기여하고자 그의 교육용 피아노 작품인 <시적인 순간>에 나타난 음악적 특징을 살펴보았으며, 중급 학생들에게 효과적인 교수방법을 제시하였다. <시적인 순간>은 총 8곡으로 구성되어있으며 이 중 ‘철새’, ‘블루스 왈츠’, ‘나비 래그타임’, ‘서부기차’를 살펴보았다. ‘철새’는 편안하고 서정적이며 아르페지오와 당김음 페달 교육에 효과적이다. ‘블루스 왈츠’는 불분명한 조성감으로 몽환적 분위기를 자아내며 리듬적 유연함을 배울 수 있다. ‘나비 래그타임’은 스윙 리듬과 다양한 아티큘레이션의 표현을 공부할 수 있다. ‘서부기차’는 빠르고 긴장감을 유발하는 곡으로 다양한 페달의 사용을 습득할 수 있다. 이 곡들은 길이가 짧고 단순하며, 다양한 음악양식과 재즈적인 요소를 지니고 있어 중급 학생들이 흥미롭게 학습할 수 있다. 본 논문을 통해 더 많은 교육용 레퍼토리가 확대되고 그의 교육용 피아노 작품들에 대한 관심과 연구가 이어지길 기대한다. Christos Tsitsaros(b. 1961) is a Professor of Piano Pedagogy at the University of Illinois in Urbana-Champaign, IL in the United States, and has composed many educational piano pieces. On the purpose of providing information on his compositions, which are not well known in Korea, and contributing to expand educational piano repertoire, this article examines the musical features of his < Poetic Moments > and suggests effective teaching methods for intermediate level students. < Poetic Moment > consists of a total of 8 character pieces: ‘Migrating Birds’, ‘Blues Valsette’, ‘Butterfly Rag’, and ‘Westbound Train’ among them were investigated. ‘Migrating Birds’ is easy to listen, lyrical and effective for polishing arpeggio skills and syncopated pedaling. ‘Blues Valsette’ creates a dreamy atmosphere with complex harmonies and students may learn rhythmic flexibility. ‘Butterfly Rag’ employs swing rhythm and diverse articulations. ‘Westbound Train’ has fast running tempo increasing tension and good for learning various pedaling. Each piece is short and simple attracting intermediate level students’ interest by conveying various musical styles and jazz elements. Through this article, I hope that more educational repertoire will be expanded and interest and research on Tsitsaros’ educational piano compositions will continue.

Objective:We studied the effect of Hyu-Sig-Gong-Gan and Hye-Ah-Rim on several evaluations and compared the two programs. We then investigated factors associated with the difference between pre- and post-ratings. Methods:Thirty-six patients were randomized to Hyu-Sig-Gong-Gan (n=23) or Hye-Ah-Rim (n=13). We tested for the effect of each program on several evaluations and compared the two programs through Zarit Burden Interview (ZBI), Center for Epidemiologic Studies-Depression Scale, Dementia Attitude Scale (DAS)-intelligence, DAS-comfort and DAS-total. We then investigated whether the difference between pre- and post-rating depends on other factors. Results:We observed significant positive effect of Hyu-Sig-Gong-Gan on DAS-comfort (t=1.843, p=0.039) and significant positive effect of Hye-Ah-Rim on ZBI (t=-2.327, p=0.019), DAS-comfort (t=2.241, p=0.022), and EuroQol-5 Dimensions-Visual Analogue Scale (t=2.537, p=0.013). For comparing the two programs, we found a lack of evidence for the difference in any of the five commonly observed evaluations. In the secondary analysis, we observed a strong trend that the two programs were particularly effective for caregivers with negative pre-ratings. Conclusion:The two programs showed positive effects on the various evaluations, but some evaluations could not reach statistical significance. The programs appear to be particularly helpful for those who are in need before the program participation.

Lim, Hye-Soon. 2002 Language Mixing in the Bilingual Child: A Case Study, The History of English, 13. This paper is to support the universality of language development through the analysis of language mixing in the bilingual child. In the bilingual development children have two distinct linguistic systems to which they are exposed. With two languages they employ language mixing either when they lack the lexical entry in the appropriate language or when the mixed entry is more salient to the child. When these mixes occur the structural consistency of the utterance is maintained depending on the situation. Their language mixing shows the competence to differentiate two linguistic systems. Key words: bilingual, mixing, objectification telegraphese, universality

Deadbeat predictive direct power control of interleaved buck converter‑based fast battery chargers for electric vehicles

Hye‑Won Choi,Seok‑Min Kim,Jinwoo Kim,Younghoon Cho,Kyo‑Beum Lee 전력전자학회 2020 JOURNAL OF POWER ELECTRONICS Vol.20 No.5

This paper presents a deadbeat predictive direct power control (DB-DPC) scheme for a fast battery charger to improve its dynamic performance and stability. Recently, battery chargers have been adopting paralleled multi-leg converters based on silicon carbide (SiC) devices to increase power capacity, which reduces the charging duration. However, the inherent instability of the battery is regarded as a crucial issue during the fast charging process. Therefore, the proposed DB-DPC provides a stable steady state since it includes real-time estimation of the variable battery impedance. Furthermore, the DB-DPC effectively minimizes the rising and settling time, which demonstrates fast-dynamic response characteristics when compared to proportional–integral (PI) control. The control performance is verified by various simulation and experimental results.

Lee, Hye-Kyung, 2012, linguistic Variations between English News Headlines in the U.S. and Those in Korea, Linguistic Research 29(2), 329-350, This paper aims to address the similarities and differences between headlines of English political news in America and those in Korea. Acknowledging the contribution of the previous research towards the understanding of news headlines, the current paper investigates how the composing of news headlines is influenced by and interrelated with extra-linguistic factors such as the consideration of the target audience`s knowledge states or interests. For this purpose, two sets of data are collected from major online news sites within both countries and the collected data are classified according to the working criteria, especially in terms of employed structural patterns. The results regarding the comparison of the two sets of headlines reveal that headlines in Korean data employ shorter sentential headlines and a smaller variety of tense/aspect of sentences compared to American English counterparts. It is also discovered that cultural factors such as naming conventions practiced in the linguistic/cultural communities are taken into account. These differences are attributed to the consideration of the target audience`s multi-faceted states such as knowledge states, beliefs, or interests. At the same time, the two sets of data show similarities in terms of the variety of structural patterns they deploy.

Polystyrene microplastics induce mortality through acute cell stress and inhibition of cholinergic activity in a brine shrimp

Hye‑Jin Eom,Sang‑Eun Nam,Jae‑Sung Rhee 대한독성 유전단백체 학회 2020 Molecular & cellular toxicology Vol.16 No.3

Backgrounds The environmental impacts of microplastics (MPs) are increasingly of concern, particularly for their sources, global distribution, and persistency in aquatic ecosystems. Although the ubiquitous and persistent nature of MPs in waterbodies is evident, their effects and health implications for aquatic animals are still open to debate. Objective The brine shrimp, Artemia franciscana was exposed to different concentrations (1–1000 particles mL− 1) of four sizes (1, 3, 6, and 10 μm) of non-functionalized polystyrene microbeads. To measure MPs effects, several physiological and biochemical parameters such as ingestion and egestion, stress biomarkers [e.g., heat shock protein 70 (hsp70) family, enzymatic activities of catalase (CAT) and superoxide dismutase (SOD)], acetylcholinesterase (AChE) activity, and survival rate for 30 days were analyzed. Results Exposure to waterborne MPs showed clear ingestion and egestion in A. franciscana. Exposure to relatively larger sizes of 1000 particles mL− 1 MPs dose–dependently increased mRNA expression of hsp70 families and enzymatic activities of CAT and SOD within 96 h. Significant inhibitory effects on AChE activity were observed in response to 1000 particles mL− 1 with increases in mortality for 30 days. Thirty-day survival of juveniles was dose-dependently affected, with greater effects seen at 1000 particles mL− 1 of MPs. Conclusion Our results suggest that MPs exposure to the early stages of brine shrimp could be detrimental for population maintenance through inhibition of cholinergic system and the induction of acute cell stress, including oxidative stress.

Determination of the optimum porosity for 2‑CEES adsorption by activated carbon fiber from various precursors

Hye‑Min Lee,Byeong‑Hoon Lee,Ju‑Hwan Kim,Kay‑Hyeok An,Soo‑Jin Park,Byung‑Joo Kim 한국탄소학회 2019 Carbon Letters Vol.29 No.6

In this study, we prepared ACFs with a high specific surface area from various precursors (rayon, pitch, and oxidized polyacrylonitrile-based fibers) by a steam-activation technique and investigated the effects of the micropore and mesopore fraction on 2-CEES adsorption behaviors. The activation time was precisely controlled so that the activation yield was in the range of 35–40% to ensure the mechanical properties of the ACFs. The N2 adsorption isotherm characteristics at 77K were confirmed by Brunauer–Emmett–Teller, Barrett–Joyner–Halenda and non-local density functional theory equations. The adsorption capacities of the ACF were measured by breakthrough experiments in the gas phase (750 μg/mL of 2-CEES in N2 flow). The removal efficiency of the ACFs was evaluated and compared with that of AC. From the results, specific surface areas and total pore volume of the ACF were determined to be 1380–1670 m2/g and 0.61–0.82 cm3/g, respectively. It was also observed that various pore characteristics of ACF were found to be dependent on crystallite structure of each precursor. The break through time (C/C0 = 0.10) was in the order of Oxi-Pan-H-9-2 < Saratoga AC < Rayon-H-9-3 < Pitch-H-9-4. This indicates that 2-CEES adsorption capacity could be a function not only of specific surface area or total pore volume, but also of sub-mesopore volume fraction in the range of 1.5–2.5 nm of adsorbents.

Gaol, Hye-Won, 2012, A Linear Regressional Analysis of Pith-Its in English, Linguistic Research 29(1), 21-44. Building up on Choi`s (2011) research that identifies the features of the instrument-taking predicates that influence the presence of instrument with-PPs, the current study explores to analyze the BYU-BNC corpus data of instrument with-PPs with a linear regression model. By building a multiple linear regression model which can deal with identified predictor variables simultaneously, this paper tries to explain the frequencies of instrument with-PPs and their nature of argumenthood by combinations of predictor variables. This modeling analysis can be a useful step toward studying gradient argumenthood via a more complex evaluation of a variety of morphological, syntactic, and semantic factors.
