Child reduction of /s/+C onset clusters - /s/ perceived as an unstressed degenerate syllable

Bo-Young Kwon(권보영) 한국음운론학회 2008 음성·음운·형태론 연구 Vol.14 No.1

  This paper examines variable reduction patterns in sC (s = strident, C = consonant) onset consonant clusters, which have been observed in the development of English and Dutch child language. The /s/ in sC onset clusters has been viewed as an extrasyllabic segment in several previous studies on child consonant cluster reduction due to its properties which resist fitting into a canonical syllabic template. In this study, I take the next step by providing a model for child cluster reduction, Onset Competition Model. Under this model, /s/ in sC clusters in child phonology is represented as a degenerate syllable (lacking a nucleus) that is perceived as unstressed by children. When it comes to the selection mechanism for the optimal onset of a reduced syllable, OCM provides two principles: a) a stress preference and (b) a sonority preference, both of which are empirically well documented in child phonology. It will be shown that variable reduction patterns in sC clusters are the outcome of competition between the two principles for retaining maximal perceptual contrast. It will also be shown that OCM illustrates another realm of evidence for perceptually based accounts in phonology.

본 연구는 학교 밖 청소년들이 겪을 수 있는 어려움들 중 진로장애와 사회적낙인감을 감소시킬 수 있는 요인들을 탐색하고 그 효과를 검증하고자 실시하였으며, 특히 환경적 요인으로써 사회적자본과 심리적 요인으로써 자아탄력성의 영향을 살펴보았다. 보다 구체적으로, 사회적자본과 자아탄력성은 진로장애 및 사회적낙인감을 감소시킬 것이라 가정하였으며, 사회적자본은 자아탄력성을 매개하여 사회적낙인과 진로장애에 영향을 준다고 가정하였다. 본 연구의 가설들을 검증하기 위하여 한국청소년정책연구원에서 수행한 「학업중단 청소년 패널조사」의 5차년도 데이터를 활용하여 구조방정식모형으로 분석하였다. 연구 결과를 보면, 사회적자본과 자아탄력성은 진로장애와 사회적낙인감에 직접적인 영향이 있었으며, 사회적자본은 자아탄력성을 통하여 진로장애에 영향을 주었으나 사회적낙인감에는 별다른 영향이 없었다. 이러한 연구 결과의 시사점과 제안점을 논의하였다. This study explored factors to reduce career barriers and social stigma that dropout youth may experience and the effects on those variables. Especially, the study was interested in the effects of social capital as an environmental factor and resilience as a psychological factor. The study hypothesized that social capital and resilience would reduce career barriers and social stigma directly, and the effect of social capital on two dependent variables would be mediated by resilience. Data of 「Dropout Youth Panel Survey」was analyzed to test the hypothesis. The result showed that social capital and resilience directly influenced career barrier and social stigma. Also, social capital influenced career barrier through resilience, but the mediation effect of resilience on social stigma was not significant. The study implications and limitations were discussed.

The purpose of this study was to investigate the effects of Core stability exercises on Dynamic Balance in Rhythmic Gymnastics. Subjects for this study were ten members of the Korean National Rhythmic Gymnastics Team. Their age(years), height(cm) and mass(kg) were 14.9years, 152.2cm, 38.3kg. Subjects exercised everyday for sixty minutes per session overs eight weeks period. The Core stability exercise program is designed to strength, power, proprioceptive, neuromuscular control at regular practice for Rhythmic Gymnastics. The Kistler 9281B Force Platform was used to evaluate ground reaction force(GRF) variables while pivot B value. The independent t-test via SPSS 12.0 was used for statistical analysis. After eight weeks, there was a significant difference in lateral(t=2.274, p< .05), anterior/posterior(t=-1.692, p< .01) and vertical(t=2.49, p< .05) range variables. In addition, the lateral minimum force(t=-3.506, p< .01) and anterior/posterior(t=2.463, p< .05) and vertical(t=2.520, p< .05) maximum force variables decreased. In Conclusion, the present results show that Core Stability exercises could improved dynamic balance.

알코올중독자 자녀의 모래놀이치료 사례연구

권보영(Kwon, Bo Young) 한국모래놀이치료학회 2016 모래놀이상담연구 Vol.12 No.1

본 연구에서는 알코올중독자의 자녀가 경험하는 역기능적 심리, 사회적인 문제의 감소와 긍정적인 자아정체성의 형성에 모래놀이치료가 미치는 효과성에 대해 알아보고자 한다. 대상아동은 13세 여아로 알코올중독자의 자녀이며 부에 의한 아동학대로 인하여 원가정에서 분리되어 시설보호 되었다. 내담아동은 높은 불안, 낮은 자존감, 학교부적응 및 또래관계의 어려움을 호소하였다. 총 22회기의 상담이 진행되었으며 이 중 11회기의 모래놀이치료가 실시되었다. 모래놀이치료의 효과성을 살펴보고자 SCT(문장완성검사), HTP(그림검사), KFD(가족화 검사), KSD(학교장면화 검사)가 사전·사후 검사로 실시되었다. 연구 결과를 보면, 내담아동은 무의식에 억압되었던 부정적인 감정을 모래상자에 표출하였고 이로 인해 내적 에너지 수준도 증가하였다. 일상생활에서 타인과 관계하고자 하는 욕구 및 자신과 주변 환경에 대해 정확하게 탐색하려는 욕구의 증가도 관찰되었다. 이는 내담아동의 자신 및 환경에 대한 인식이 확장되고 자아존중감의 향상을 보여주는 근거로 볼 수 있다. 본 연구에서는 모래놀이치료가 알코올중독자의 자녀들의 낮은 자아존중감을 향상시키고 내면의 부정적인 감정을 표출할 수 있는 기회를 제공하여 이들이 겪고 있는 심리, 사회적 문제를 감소시키는 긍정적인 영향을 미칠 수 있다는 결과를 제시하였다. This study aims to examine the effectiveness of sand play therapy for the children of alcoholics on reducing their negative social and emotional problems and building positive slef-esteem. The client of this study was a thirteen years old girl who is the children of alcoholics. She was physically and emotionally abused by her father and protected at a facility. Her presenting complaints were anxiety, low self-esteem, difficulties in school and peer relationships. A total 22 sessions of counseling were conducted and 11 sessions were sand play therapy among them. In order to testify the effectiveness of sand play therapy, pre-post psychological tests which were SCT, HTP, KFD, and KSD conducted. During the therapeutic process, the client expressed her negative feelings on the sand tray and the level of her energy increased. As a result, her desires to be conscious about herself and her environment and her attempts to make relationships with others were increased. They are considered as the evidences that her consciousness about herself and her environment was expanded and her self-esteem was increased. The significant of this study is that sand play therapy can contribute to the children of alcoholic who has social and psychological difficulties to establish positive self-esteem.

The patterns of vowel insertion in IL phonology : the P-map account

권보영(Bo-Young Kwon) 한국음운론학회 2005 음성·음운·형태론 연구 Vol.11 No.2

In this study, I provide evidence that the P-map (Steriade 2001a, 2001b), a model of generic listeners' perceptual abilities and biases, is responsible for the patterns of vowel insertion in Korean speakers' production of English consonant clusters. The experimental findings in the study demonstrate that vowel insertion is more likely to occur a) when C₁ (the first consonant of a cluster) is a stop than a strident or a sonorant and b) when C₁ is a voiced stop than a voiceless stop. This study presents two proposals to account for the attested patterns of vowel insertion. First, following Côté (2000), I propose that the likelihood of vowel insertion in consonant clusters correlates with the perceptual salience of a segment in contrast: the weaker the perceptual cues of a segment, the more likely it is to be modified. In a similar vein, I also propose that second language (L2) learners are guided by the P-map when faced with L2 phonotactic constraints that are not part of their native languages. That is, the P-map knowledge leads L2 learners to choose the output form with relatively minimal modification of the input in terms of perceptual similarity. These two proposals are supported by the author's auditory similarity judgment experiment involving the same population as in the production study. This perception experiment shows that there exist perceived similarity differences between unepenthesized input and epenthesized output and these perceived similarity differences actually correlate with the patterns of vowel insertion in Korean speakers' production data.

플라즈마 표면처리에 의한 Silk/PLA 바이오복합재료의 계면접착

견섬유와 폴리라틱산(PLA) 사이의 계면접착 특성을 향상시키기 위하여 천연섬유 표면을 아르곤과 에틸렌 플라즈마로 각각 처리하였다. 플라즈마 표면처리 후, 견섬유의 표면 모폴로지와 접착이 크게 변화하였다. 다음의 여러 플라즈마 처리조건이 본 연구에 사용되었다: 10, 25, 50 그리고 150 W의 전력, 1, 3, 5, 7 그리고 10분의 처리시간 및 10과 50 sccm의 가스흐름속도, 플라즈마 처리된 Silk/PLA 바이오복합재료의 계면전단강도는 단섬유 micro-droplet debonding 시험방법으로 측정하였다. 결과는 Silk/PLA 바이오복합재료의 계면접착을 향상시키기 위한 최적의 플라즈마 처리 조건을 제공하여 주었다. Silk fibers were subjected to argon and ethylene plasma treatments in order to improve the interfacial adhesion with polylactic acid (PLA). After the plasma surface treatment, the surface morphology and surface adhesion of silk fibers to the PLA resin were largely changed. Various plasma treatment conditions were used in this work: 10, 25, 50, 100 and 150 W of electric power, 1, 3, 5, 7 and 10 minutes of treatment time, and 10 and 50 sccm of a gas flow rate. The interfacial shear strength of plasma-treated Silk/PLA biocomposites was measured by a single fiber micro-droplet debonding test method. The result provided an optimal plasma treatment condition to obtain the improved interfacial adhesion in the Silk/PLA biocomposites.
