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.

음악작품 속에 나타난 항쟁 묘사의 표현기법 연구

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.

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

Dohee Kim,Kyoung Suk Hwang,Kyung Suk Lee 대한인간공학회 2012 대한인간공학회지 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.

U.S.-China Hegemonic Competition and Power Transitions: Focusing on the Role of Allies

Dohee Kim 한국학술연구원 2024 Korea Observer Vol.55 No.1

The U.S.-China hegemonic competition is clearly underway, as the Biden administration acknowledges China as the only challenger to the existing global hegemony. This recognition has initiated a power struggle between the two, despite neither possessing absolute national power for complete dominance. This article goes beyond the traditional debate of whether China will eventually surpass the U.S. and focuses on deriving pertinent implications. The role of allies in shaping the U.S.-China competition is gaining significance. The U.S. is restructuring the global supply chain to exclude China, creating overlapping mini-lateral cooperative networks with traditional allies and friendly nations. Conversely, China is expanding its influence through traditional multilateral cooperation, aligning with alliance transition theory. Furthermore, mid-sized countries, especially pivotal ones are assuming a more critical role. This situation has implications for ROK government's foreign policy, which aims to play an active role as a Global Pivotal State emphasizing liberal democratic values and common interests.

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>

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.

The Influence of Demographics, Experience, and Expertise on the Destination Image of Ski Resorts

Dohee Kim 한국관광학회 2010 International Journal of Tourism Sciences Vol.10 No.3

This study examines the effects of demographics, experience, and expertise on destination image formation in the ski resort context. It aims to propose an intervening variable - expertise - as a function of both the effects of demographics (gender, age, and income) and experience, on destination image assessments. The data were collected as part of a larger survey of ski resort images and ski vacation behavior. The findings use various statistics to support relationships between three demographic factors, experience, and expertise, and confirm their linkages with image assessments. Using MANOVA, it was found that affective comfort image is differentiated more by the expertise levels of skiers than by cognitive image, indicating that expertise influences affective image formation.

The 2017 Korean National Growth Charts for children and adolescents: development, improvement, and prospects

Kim, Jae Hyun,Yun, Sungha,Hwang, Seung-sik,Shim, Jung Ok,Chae, Hyun Wook,Lee, Yeoun Joo,Lee, Ji Hyuk,Kim, Soon Chul,Lim, Dohee,Yang, Sei Won,Oh, Kyungwon,Moon, Jin Soo The Korean Pediatric Society 2018 Clinical and Experimental Pediatrics (CEP) Vol.61 No.5

Growth charts are curves or tables that facilitate the visualization of anthropometric parameters, and are widely used as an important indicator when evaluating the growth status of children and adolescents. The latest version of the Korean National Growth Charts released in 2007 has raised concerns regarding the inclusion of data from both breastfed and formula-fed infants, higher body mass index (BMI) values in boys, and smaller 3rd percentile values in height-for-age charts. Thus, new growth charts have been developed to improve the previous version. The 2006 World Health Organization Child Growth Standards, regarded as the standard for breastfed infants and children, were introduced for children aged 0-35 months. For children and adolescents aged 3-18 years, these new growth charts include height-for-age, weight-for-age, BMI-for-age, weight-for-height, and head circumference-for-age charts, and were developed using data obtained in 1997 and 2005. Data sets and exclusion criteria were applied differently for the development of the different growth charts. BMI-for-age charts were adjusted to decrease the 95th percentile values of BMI. Criteria for obesity were simplified and defined as a BMI of ${\geq}95th$ percentile for age and sex. The 3rd percentile values for height-for-age charts were also increased. Additional percentile lines (1st and 99th) and growth charts with standard deviation lines were introduced. 2017 Korean National Growth Charts are recommended for the evaluation of body size and growth of Korean children and adolescents for use in clinics and the public health sector in Korea.
