베베른의 ‘피아노 변주곡 Op. 27’과 메시앙의 ‘음가와 강세의 모드’에 나타난 음렬기법과 총렬기법 연구 및 연주를 위한 제안

김도희 ( Kim¸ Dohee ) 한국피아노교수법학회 2015 음악교수법연구 Vol.15 No.-

본 논문은 베베른의 < 피아노 변주곡 Op. 27 >과 메시앙의 <음가와 강세의 모드> 연구를 통하여 음렬주의와 총렬주의 이론을 이해하고 효과적으로 연주에 나타나도록 고찰하는 것을 목적으로 한다. 음렬주의와 총렬주의에 의한 피아노 곡들은 음렬이론에 대한 이해가 어렵고 강약, 주법, 리듬 등 음렬화 된 여러 음악요소의 미세한 차이를 연주에 반영하기 까다로워 실제 연주가 회피되는 경향이 있다. 음렬 및 총렬기법을 연주에 잘 반영하기 위해서는 음렬화 된 음고, 음가, 리듬, 강약에 대한 이론을 먼저 이해하는 것이 필수적이다. 이를 위하여 베베른의 < 피아노 변주곡 Op. 27 >과 메시앙의 <음가와 강세의 모드>에 나타난 음렬과 총렬기법을 분석하였고 이러한 기법들이 연주에 잘 반영되기 위한 방법들을 다각적으로 모색하였다. 본 연구를 통해 피아니스트들이 음렬기법과 총렬기법을 보다 폭넓게 이해해서 이러한 기법이 사용된 피아노 작품들을 연주무대에 보다 자주 올려 다양한 연주 레파토리 구축에 기여할 것으로 생각된다. The purpose of this study is to understand the theory of Serialism and Total Serialism through researching Webern's Piano Variation Op. 27 and Messiaen's Mode de valeurs et d'intensités and to examine how the theory can be effectively appeared in performance. Performance of piano pieces based on Serialism and Total Serialism is tend to be avoided because understanding serial technique theory is difficult and hard to reflect subtle differences of various music elements such as dynamics, attack and rhythm in series in actual performance. For Serial and Total serial techniques to be brought out well in performance, it is necessary to understand theory of pitch, value of note, rhythm and dynamic in series in advance. To achieve this purpose, Serial and Total serial techniques in Webern's Piano Variation Op. 27 and Messiaen's Mode de valeurs et d'intensités are studied and methods to reflect these techniques well in performance are searched in various ways. It is expected that though this research, pianists would understand widely Serial and Total serial techniques and perform more often piano pieces based on these techniques at a stage building diverse performance repertoire.

김도희 ( Kim¸ Dohee ) 한국피아노교수법학회 2021 음악교수법연구 Vol.22 No.1

인간이 몸담은 사회의 여러 현상과 활동은 음악작품 속에 다양한 방법으로 묘사되어 왔다. 본 논문은 권력의 압제에 대항하는 항쟁의 모습이 서로 다른 장르의 음악작품 속에서 어떻게 표현되었는지 고찰하였다. 먼저 음악과 사회의 관계와 관련 이론을 살펴보고, 제프스키의 피아노 변주곡 <단결한 민중은 결코 패배하지 않는다!>, 로시니의 오페라 <윌리엄 텔>, 윤이상의 교향시 <광주여 영원히!>를 연구대상으로 하여 각 작품의 작곡가, 작품과 관련된 사회사, 작품 속에 묘사된 항쟁의 다양한 표현기법을 분석하였다. 분석 결과 <단결한 민중은 결코 패배하지 않는다!>는 칠레의 민주화운동과 관련된 저항가요를 주제로 작곡되었으며, 단결의 의미가 상징적으로 표현되었고, 항쟁 현장의 소리 모방과 항쟁과 관련될 수 있는 나타냄말이 쓰였으며, <윌리엄 텔>에서는 오스트리아의 압제에 전설의 명사수 텔과 스위스 민중이 함께 대항하는 내용이 등장인물들의 노래 가사로 표현되었고, <광주여 영원히!>는 한국의 5·18 민주화운동을 음악으로 형상화한 교향시로 저항, 애도, 재행진의 세 부분 구성 속에 항쟁의 여정이 묘사되었음을 알 수 있었다. 본 연구를 통해 음악과 사회의 연관성에 관한 연구가 더욱 촉발되고, 이와 관련된 작품의 이해와 해석에 대한 다각적인 분석과 연구가 더욱 확대되기를 기대한다. Various phenomena and activities in society in which humans are involved have been described in different ways in musical works. This paper examines how the appearance of the resistance against the oppression of power was expressed in musical works of different genres. First of all, the relationship between music and society and related theories are examined and Rzewski’s piano variation < The people united will never be defeated! >, Rossini’s opera < William Tell >, and Isang Yun’s symphonic poem < Exemplum in memoriam Kwangju > are selected as research subject and composer of each work, the social history related to each work, and various expression techniques on resistance described in each work are analyzed. The analysis results are as follows. < The people united will never be defeated! > is composed on the theme of resistance song related to the Chilean democratization movement, and the meaning of unity is symbolically expressed, and imitation of the sound from resistance scene and terms and words which could be related to the resistance are used in the work. In < William Tell >, the story in which the legendary archer Tell and the Swiss people resist against Austria's oppression are expressed through the lyrics sung by characters. < Exemplum in memoriam Kwangju > is a symphonic poem that embodies musically the May 18 democratization movement in Korea, and journey of resistance consisting of uprising, mourning and a re-marching is described in the work. It is hoped that research on the relationship between music and society will be more stimulated and multilateral analysis and research on the understanding and interpretation of works related to this matter will be further expanded through this study.

Case Analysis of the R.O.K.-U.S. Alliance Burden-Sharing through Theoretical Approaches to the Evolution of an Asymmetric Alliance

Dohee Kim 한국학술연구원 2020 Korea Observer Vol.51 No.1

In the early stages of the R.O.K.-U.S. alliance, the U.S. took full responsibility for providing security in the alliance. However, as Korea progressed through economic growth and democratization, asymmetry lessened within the alliance and consequently defense cost-sharing issues emerged. In fact, while South Korea has relatively little inducement for free-riding due to relying heavily on the alliance to counter the threat from North Korea, the easing of asymmetry has complicated the cost-benefit calculation for the alliance and has replaced the traditional security-autonomy tradeoff. In particular, problems may arise due to an increased risk of entrapment due to differences in threat perception between the two countries. In this regard, defense cost-sharing is a critical issue in maintaining the alliance, not just in terms of sharing the cost of stationing U.S. forces in South Korea, but in the process of realigning and renewing the effectiveness of the alliance.

Foot Type Classification of Korean Male Farmers for Ergonomic Work Shoes Design

Dohee Kim,Kyoung Suk Hwang,Kyung Suk Lee 대한인간공학회 2012 大韓人間工學會誌 Vol.31 No.6

Objective: The aim of this study is to identify foot shapes of Korean male farmers by classifying their foot types using 3D scan data and analyzing the characteristics of each type. Background: The increasing demands for anthropometric information for the design of machinery and personal protective equipment to prevent occupational injuries has necessitated an understanding of the anthropometric differences to be found among occupations. Static stooped posture and squatting posture are so common in Korean farmers that anthropometric deformation in foot especially seems to occur easily. Method: 366 Korean male farmers volunteered for this study from 16 different farming villages nationwide from 2009 to 2011. Subjects were categorized into 4 age groups from 40s to 70s. Their right feet were measured by using 3D foot scanner, the anthropometric dimensions were composed of 40 items. Results: The 8 major factors affecting the foot shapes were extracted. From these factors the foot shape of Korean male farmers was classified into 3 Foot types. Foot type 1 showed severe deformation in toe 1, type 2 had a narrow shape and type 3 had a wider width for its length. Conclusion: There were some differences in foot shape and types between farmers and the public. The most characteristic foot type in Korean male farmers was type 3. Application: The results of identifying foot shapes of Korean male farmers might provide the useful information for designing ergonomic farm work shoes.

Mutants defective in the production of encapsulin show a tan-phaselocked phenotype in Myxococcus xanthus

Dohee Kim,Juo Choi,Sunjin Lee,현혜숙,Kyoung Lee,Kyungyun Cho 한국미생물학회 2019 The journal of microbiology Vol.57 No.9

Myxococcus xanthus, a myxobacterium, displays phase variation between yellow phase and tan phase. We found that deletion of the encA gene encoding encapsulin and the encF gene encoding a metalloprotease causes formation of tan colonies that never transform into yellow colonies. The encA and encF mutants were defective in the production of DKxanthene and myxovirescin. They did not produce extracellular polysaccharides; hence, the cells did not aggregate in liquid and showed reduced swarming on agar plates. The mutants had defective sporulation, but were rescued extracellularly by wild type cells. All these traits indicate that the encA and encF mutants are likely to be tan-phase-locked, and encapsulin has a close relationship with phase variation in M. xanthus. The encA and encF genes are localized in the same gene cluster, encBAEFG (MXAN_3557~MXAN_3553). Unlike the encA and encF genes, deletion of other genes in the cluster did not show tan-phase-locked phenotype.

Improving the storage performance of smartphones through journaling in non-volatile memory

Dohee Kim,Eunji Lee,Sungyong Ahn,Hyokyung Bahn IEEE 2013 IEEE TRANSACTIONS ON CONSUMER ELECTRONICS - Vol.59 No.3

<P>According to the recent studies on the smartphone performance analysis, the primary performance bottleneck of smartphones is storage systems rather than wireless networks or processors. The key reason behind this undesirable result is the journaling function of a lightweight database library used by various smartphone applications. This paper quantifies the overhead of journaling on the performance of smartphones and presents a novel storage architecture that eliminates this overhead by using nonvolatile memory technologies. Specifically, the proposed architecture adopts a new journaling scheme that provides high storage performance of smartphones without any loss of reliability. The prototype of the proposed architecture has been implemented on the mobile platform based on Linux. Measurement studies with smartphone benchmarks show that the proposed journaling architecture improves the storage performance by 20-278% compared to original journaling. Performance studies with real applications such as internet games, video players, and web browsers also show that the performance improvement is in the range of 23-69%.</P>

S-399 Low vitamin D status is associated with Hashimoto’s thyroiditis

( Kim Se Weon ),( Won Sang Yoo ),( Hee Jin Kim ),( Hyun-kyung Chung ),( Dohee Kim ) 대한내과학회 2016 대한내과학회 추계학술발표논문집 Vol.2016 No.1

Objective: The association of low vitamin D status with autoimmune thyroid disease (AITD), which includes Hashimoto’s thyroiditis (HT) and Graves’ disease (GD), is controversial. The aim of this study was to investigate the correlation between vitamin D insufficiency and AITD, HT, and GD. Design: Our cross-sectional study included patients who visited a tertiary hospital for thyroid evaluation or follow-up. A total of 776 patients in whom serum 25-hydroxyvitamin D [25(OH)D], thyroid function, and anti-thyroid antibodies had been measured were analysed retrospectively. Vitamin D insufficiency was defined as a serum 25(OH)D level <75 nmol/L. Results: The prevalence of vitamin D insufficiency was significantly higher in the 369 patients with AITD than in the 407 without AITD (46.1% vs. 37.1%, p=0.011), and higher in the 221 patients with HT than in those with GD or non-AITD (48.9% vs. 41.9%, 37.1%, p=0.017). Among HT cases, patients with overt hypothyroidism had a significantly higher prevalence of vitamin D insufficiency (60.4% vs. 44.1%, 21.7%, 37.1%, respectively, p<0.001) and lower 25(OH)D levels (80.1±47.7 vs. 99.34±61.2, 110.3±69.9, 99.6±53.7 nmol/L, respectively, p=0.009) compared with those with euthyroidism and subclinical hypothyroidism, or those without AITD. Serum 25(OH)D levels were significantly negatively correlated with serum thyroid stimulating hormone (TSH) levels after adjustment for age, sex, body mass index, and sampling season (r= -0.127, p=0.013). Conclusions: Vitamin D insufficiency was associated with AITD and HT, especially overt hypothyroidism. Low serum vitamin D levels were independently associated with high serum TSH levels.
