강동권 ( Dong Kwon Kang ),강서정 ( Suh Jung Kang ),유연주 ( Yeon Joo Yu ) 한국운동역학회 2013 한국운동역학회지 Vol.23 No.1

본 연구의 첫 번째 목적은 540° 뒤후려차기 동작의 운동역학적 변인들을 정량화 하는 것이고, 두 번째 목적은 지상동작이 공중동작에 미치는 영향을 밝혀내는 것이다. 지상회전 구간에서의 수직지면반력(GRF)을 분석한 결과 지상에서 180° 회전하면서 나타나는 수직지면반력(GRF)이 체중보다 낮아지는 것을 발견할 수 있었다. 이러한 결과는 반동(counter movement)을 사용하여 높게 점프하려는 전략으로 반동 동작시 발생하는 신장성수축으로 인한 근육과 건에 저장된 탄성에너지를 사용하여 높게 점프하는 SSC(stretch shortening cycle)시스템(Komi, 2003)을 사용하는 것이다. 이렇게 반동을 사용하는 것이 반동을 사용하지 않았을 때보다 높게 점프할 수 있다(Bobbert, Gerritsen, Litjens & Soest, 1996). 즉, 지상에서 회전하는 동안에는 반동 동작을 수행하지 않는 것으로 보이지만 실제로는 반동 동작을 하는 것으로 나타났다. 540° 뒤후려차기에서 각 구간에서 중요하다고 판단되어 정의한 8개의 변인들을 분석한 결과 8개의 변인에서 비슷한 패턴과 적은 표준편차를 나타냈다. 이러한 결과는 11명의 엘리트 시범단원들이 540° 뒤후려차기를 수행하는데 있어서 모두 비슷한 전략을 가지고 있는 것으로 해석할 수 있으며, 이러한 결과는 추후 540° 뒤후려차기를 연구하는 데 유용한 기초자료로 활용 될 수 있을 것이다. 540° 뒤후려차기는 돌개차기와 뒤후려차기가 결합된 복합 기술이다. 즉, 540° 뒤후려차기는 돌개차기로 점프하여 뒤후려차기로 차기기술을 수행한다. Kang과 Kim(1996)은 엘리트 선수의 돌개차기 동작을 연구하였는데, 엘리트 겨루기 선수들의 돌개차기 동작 수행시 지상회전 구간의 소요시간은 0.59±0.06 sec로 나타나 본연구의 지상회전 구간의 소요시간인 0.4±0.04 sec보다 길게 나타났다. 이는 득점을 위하여 빠르게 동작을 수행하는 엘리트 겨루기 선수들보다 540° 뒤후려차기를 전문적으로 수행하는 엘리트 시범단원들이 지상회전 구간에서 더 빠른 지상회전 동작을 수행하는 것으로 사료된다. 540° 뒤후려차기는 차기 구간에서 뒤후려차기를 동작을 수행한다. 이러한 뒤후려차기는 공을 던지는 듯 한 동작의 돌려차기(Throw-like motion)와 미는 형태의 옆차기(Pushlike motion)의 특징이 혼합된 복합운동(Kim, Jin & Shin, 1995; Choi, Lee, Kim & Kim, 2007)으로 복잡한 메커니즘을 가지고 있고, 돌려차기에 비해 뒤후려차기의 발끝 속도는 느리다(Kim, Y. K. & Kim, Y. H., 2010). Ha와 Kim(2009)은 엘리트 시범단원 3명을 대상으로 뒤후려차기의 발끝 속도를 분석한 결과 14.43±2.00 m/sec로 본 연구의 8.78±0.76 m/ses 보다 빠르게 나타났다. 하지만 선행연구는 한발을 지면에 딛고 기술을 수행한 것이고, 본 연구의 뒤 후려차기는 공중에서 수행 했다는 차이점을 가지고 있다. 본 연구의 두 번째 목적인 지상동작이 공중동작에 미치는 영향을 알아보기 위하여 각 구간별 변인들로 상관분석을 실시한 결과 예상하지 못한 결과가 나타났다. 기본적으로 체공시간(FT)과 충격량(impulse)으로 수직점프높이를 추정 할 수 있다(Richter, Rapple, Kurz & Schwameder, 2012; Yuktasir & Kaya, 2009). 따라서 두 변인간의 상관은 높게 나타나는데 본 연구의 결과에서는 체공시간(FT)과 충격량(impulse)에서 상관이 유의하게 나타나지 않았다. 또한 수직신체무게중심(COG)과 충격량(impulse)도 상관관계가 높을 것으로 예상하였으나, 본 연구의 결과 유의한 상관이 나타나지 않았다. 이는 점프동작 이외에 회전동작의 개입으로 인한 결과(Lee & Kim, 1996)로 판단된다. 또한 차기동작인 뒤후려차기를 수행하기 위하여 상체를 숙이는 것에 기인하여 수직신체무게중심(COG)과 충격량(impulse)의 상관이 나타나지 않은 것으로 사료된다. The aim of the study was a quantitative analysis of elite athlete`s 540o Dwihuryeochagi and effects of ground movements to the jumping height and kicking velocity. Eleven elite players(Taekwondo demonstration team) participated in this study. In order to get the kinetic and kinematic variables, ten Vicon cameras and a force plate were used. Foot segment velocity(FSV), vertical ground reaction force(GRF), impulse, ground time(GT) in phase 1, trunk angular velocity(TAV), vertical center of gravity(COG), flight time(FT) in phase 2 and kicking leg segment velocity(KSV) in phase 3 were measured and analyzed. Results indicated that there were similar patterns of variables among phases between subjects. Non-significant correlation(r=.145) between flight time(FT) and impulse was found. Also non-significant correlation(r=.119) between center of gravity(COG) and impulse was found. In conclusions, there were similar strategies in phase 1, phase 2, and phase 3 between subjects.

미시적 허구와 거시적 진실

This study aims to scrutinize how history is reflected in the following works of literature: William Shakespeare's Anthony and Cleopatra and Aphra Behn's The Widdow Ranter. Both Anthony and Cleopatra and The Widdow Ranter are concerned with people who rose to power in parallel with people who failed to do so. Both works conclude with the rise of a new order, and the tragic elements are juxtaposed with comedic traits. In other words, although the noble heroes (and at the same time, the failures) are highlighted in the plays, they make way for the better politicians or the commoners. In spite of the relative consistency of the characterization, the main characters tend to be described as ambiguous. Every person, winner or loser, is illuminated on the stage in terms of their different virtues. The writers seem to be searching for political and social solutions to the problems that they were facing back then. In that process, some fiction is inserted in the story, as a reflection of the spirit of the age. It is definite that the scientific and political development of the 17th century led to the belief in God's rationality and order, which is circulated throughout the two tragicomedies. This study, which was focused on the world views found in English literature of the 17th century, will be able to show that historical realities are inscribed in the works of literature, by means of figurative language, characterization, and symbolism.

의사소통 활동으로서의 영문학 읽기

강서정(Seojung Kang) 한국영미문학교육학회 2013 영미문학교육 Vol.17 No.2

This study explores the promotion of communication while reading literary texts. It is based on the assumption that the essence of reading is communicative activities. According to this assumption, this paper shows that, by nature, the reading of literary texts, consists of the interaction among readers as well as the interaction between the text and the readers, which is communication itself. The fundamental problem of recent English language education is in the fact that it neglects the role of learners as subjects of thought and communication. The informants of this study were six out of forty-four students whom I taught during the fall semester of 2012. The class illustrates that group discussions which involve text-self, text-world, and text-text interaction, can promote communication in the process of reading literary texts. The students improved in their ability to use the four skills of English and participated in the activities of summarizing and group discussions to the betterment of their critical communicative abilities. The group discussions in particular provided the students with opportunities to find themselves and explore the world around them while sharing a variety of experiences and interpretations in relation to the texts. The research also offers suggestions based on insights from the class. I hope that this study, which demonstrates a means of helping students to improve in the four language skills of listening, speaking, reading, and writing, will be supported by future studies.

헬레니즘과 헤브라이즘: 조이스의 『율리시스』의 로터스 먹는 종족 읽기

강서정 ( Seojung Kang ) 한국제임스조이스학회 2023 제임스조이스저널 Vol.29 No.1

James Joyce’s Ulysses presents new humanism and portrays a new image of Christ. Thereby, it deconstructs early 20th century Dublin, a city based on the two pillars of Western culture, Hellenism and Hebraism. The lotus flower paralyzes the minds of those who eat by triggering in the urge to indulge in pleasure. Joyce displays discrete forms of paralysis encountered on Dublin streets through Bloom’s eyes, including horse racing, the Irish penchant for religion, and colonial remnants that Dubliners fail to recognize. The male protagonist Bloom’s exchange of love letters with Martha Clifford is also merely lotus eating: he tries to satisfy his desires through language. Joyce also associates the image of a man floating in the sea reading a book with the properties of lotus eating, manifesting the lure of language inscribed in books as an effect of ingesting the lotus flower. Above all, the Catholic religion represents the most evident lotus in this chapter: Bloom secularizes the Eucharist during the Mass, elucidating that the body of a living man is a better means of salvation than eating a ‘dead body.’ Ulysses focuses primarily on the sexual vitality of women: however, the chapter “Lotus Eaters” attends to the reproductive abilities of men. Bloom’s immersion in the water in the final scene of the chapter amounts to the declaration that he is purifying the church as a new Christ of life. Christ in the symbolic world is replaced by Christ in the real world by connecting Christ, the Word, with the sexually inactive love letter (word), then shifting to the author’s work (book), and finally moving to Bloom’s body.

This study aims to portray a desirable English literature class based on the Person-Centered Approach by Carl R. Rogers: further, I reflect on my experiences of teaching literature. The key to this approach is the belief that a student is in the process of becoming a person with an actualizing tendency. It is a conviction as well that a student can be a fully functioning individual when learning is facilitated. So, Rogers emphasizes learning how to learn for the students. That becomes possible when teachers allow the students to be subjects of learning, while creating a warm ambiance. According to Rogers, the three qualities of a facilitator-or a teacher are genuineness(or realness, congruence), unconditional positive regard, and empathy. This paper illuminates the traits, based on which we can draw insights on English literature education. When I look back on my teaching experiences in literature classes under the influence of Rogers, I can summarize four characteristics of my classes. First, I utilize a variety of mediums, such as art, music, and creative writing assignments to make the best of the written text so that the students can engage emotionally and intellectually as a whole person. Second, I try to provide decision-making opportunities to the learners and to make them responsible for their learning. Third, I encourage my students to collaborate with their teammates in small groups where the members can express and share their responses to literary texts among themselves. Lastly, I promote communication in my classes. To sum up, the best way of understanding the Person-Centered Approach is by realizing that students already have the potential to learn and that the teachers’ attitudes and philosophy are decisive in the learning achievement of the teachers as well as their students. Students should feel free to express their responses emotionally, intellectually, and kinesthetically rather than just accepting the experts’ interpretations. And teachers should accept students’ responses preciously. They should set aside their mask of expertise, while students should learn how to use their expertise as a resource. Teachers should also give students unconditional positive regard, care, and respect. In that way, all-students as well as teachers, -would grow. This is the insight that the Person-Centered Approach by Rogers provides on English literature education.

거울의 모티프를 통한 작가적 자아성찰:

강서정(Kang Seo jung) 한국외국어대학교 영미연구소 2017 영미연구 Vol.40 No.-

본 연구는 이창래의 소설『네이티브 스피커』(Native Speaker)의 주인공 헨리(Henry Park)가 작가적 자아성찰을 하는 과정에서 거울의 모티프를 어떻게 활용하는지를 탐색한다. 거울은 글쓰기 과정에 대한 주인공의 치열한 고민을 반영하며 동시에 주인공의 개인적, 민족적 정체성을 드러내는 중요한 모티프이다. 이 소설에는 두 가지 종류의 거울에 맺히는 여러 개의 현실이 존재한다. 그 하나는 주류 백인의 시선으로 바라보는 현실이며, 다른 하나는 헨리 자신의 관점에서 미국 내 소수민족을 형상화하는 이미지이다. 작중 화자 헨리는 외부 주류 백인들의 시선에서 스스로를 바라보다가 점차 자신의 관점을 거울삼아 세상을 재현한다. 이 때 작가는 헨리가 신뢰할 수 없는 화자임을 보여주며, 그가 재현하고 싶어 하는 존 광의 이상화된 모습을 노출시킨다. 즉, 작품 속 거울들은 헨리가 외부 세계에서 인정받고자 하는 욕구, 공적인 역할에 대한 염원을 반영함으로써 그의 고민을 담고 있다. 이러한 의도적인 한계를 지닌 헨리의 혼란과 문제의식은 결국 작가 이창래의 작가적 성찰과 맞닿아 있다. 작가와 헨리는 작품의 후반으로 갈수록 서로 분리될 수 없는 존재가 되어가고, 결국 이창래는 헨리의 시선을 통해 자신의 비전을 제시하며 작품을 종결한다. This study explores how the main character Henry, the alter ego of the author Chang-rae Lee in the novel Native Speaker, creates an independent identity using the motif of the mirror. Mirrors show the author’s keen interest in writing, and simultaneously reveal authorial introspection on both the personal and national levels. The novel has two types of mirrors: one that captures immigrants’ reality through the lens of Whiteness, and the other that Henry creates from his own phenomenological perspectives. Henry begins seeing himself from a main stream perspective and finally constructs his own (national) identity. However, when formalizing the character John Kwang, the author betrays how unreliable Henry is as a narrator because he excessively idealizes Kwang. In other words, Henry projects his desired self in American society through his depiction of Kwang. Thus, Henry’s inner desires to be accepted and recognized in the mainstream and to become a public figure in America are embedded in mirrors. Henry’s confusion and interests as a writer are thus inevitably incorporated into the author’s introspection.

진 리스(Jean Rhys)의 『광활한 사가소 바다』(Wide Sargasso Sea)에 나타나는 장소의 상실과 회복

강서정(Kang, Seo-Jung) 문학과환경학회 2015 문학과 환경 Vol.14 No.1

This study stipulates how Rochester destroys Antoinette’s place identity in terms of its meaning and how she performs a ritual to bring it back in Wide Sargasso Sea by Jean Rhys. The basic cause of Antoinette’s suffering is due to the loss of place identity. Her precious place in its meaning is severely damaged by Rochester who is a colonialist and at the same time, male patriarch. To destroy the meaning of a place is an epistemological violence as serious as its physical devastation. The novel depicts the contest of place identities between Rochester and Antoinette in line with the maintenance of their own self-identities. In that process, they use different types of narratives. While Antoinette takes contextual discourses to express her place-related experiences, Rochester chooses totalizing languages. Actually, in the novel there are different kinds of conflicts in relation to meanings of the two places, which are England and the West Indies. While the West Indies are in flame with the Sun, England is a country of snow. Rochester feels a threat in the West Indies and tries to hold his English place identity there. He refuses to assimilate with the West Indies and destroys their culture, history, and meanings. Rochester also denies the identity of his wife, Antoinette. She is firstly, a stranger, then Bertha, a maniac, and then a marionette, a doll. Rochester drags Antoinette out of her own place and leads her into England. He goes one step further and makes her crazy. However, Antoinette resists by setting Rochester’s mansion on fire. That is a ritual in England, a country of snow to recreate Coulibri/Granbois of West Indies her paradise.
