박예슬 한국음악치료교육학회 2015 인간행동과 음악연구 Vol.12 No.2

The purpose of this study was to investigate music therapists’use and perception of computer-based music technology. Questionnaires were distributed either electronically or in-person to 367 music therapists with credentials. Of the 367 initially distributed questionnaires, 101 were returned and 61 were analyzed after excluding 40 incomplete responses. The survey was comprised of two sections: the use of music technology and perceived importance of music technology in music therapy practice. The results showed that 65.6% of the respondents had used music technology in their clinical practice. The most frequently used type of music technology was Finale, followed by Garage band, and Cubase. With regard to the areas where music technology was used, it was implemented primarily for adolescents for musical or emotional goals, and was applied most frequently as a musical resource. In addition, most respondents showed a positive attitude toward music technology and added that they would need to be trained to use music technology for their clinical practice. These results provide practical information on how music therapists use and perceive computer-based music technology, and its implication for music therapy clinical practice. 본 연구의 목적은 음악치료사의 컴퓨터를 기반으로 음악테크놀로지 활용 현황과 인식을 조사하기 위한 것이다. 조사를 위해 전문 자격증을 소지한 음악치료사 367명에게 온·오프라인으로 설문지를 배부하였으며 이 중 101부가 회수되었고 미완성되거나 대상자 기준에 맞지 않는 50부를 제외한 61부를 최종 분석 하였다. 설문 문항은 컴퓨터를 기반으로 한 음악테크놀로지 활용에 관한 현황, 인식, 치료사의 의견으로 구성되었다. 음악치료에서 음악테크놀로지의 활용현황에 대한 결과는 다음과 같다. 응답자 중 65.6%(40명)가 세션 내 음악테크놀로지를 활용한 경험이 있으며, 활용비율이 높은 음악테크놀로지의 종류는 피날레, 가라지밴드, 큐베이스 순으로 조사 되었다. 음악테크놀로지의 적용 현황을 살펴보면 음악 혹은 정서영역에서 청소년을 대상으로 주로 사용하며, 음악 자원으로 적용하는 형태가 가장 많이 나타났다. 대부분의 음악치료사들이 음악 긍정적으로 인식하고 있으며, 기술 습득에 대한 필요성이 확인 되었다. 이 외에도 음악테크놀로지 활용에 관한 다양한 의견이 취합되었다. 이러한 결과는 음악치료 임상현장에서 음악테크놀로지를 활용하는 현황과 이에 대한 인식에 관한 정보를 제공하고, 보다 효과적인 음악테크놀로지 활용에 대한 시사점을 제시하는 데 그 의의를 갖는다.

Class-Labeling Method for Designing a Deep Neural Network of Capsule Endoscopic Images Using a Lesion-Focused Knowledge Model

박예슬,이정원 한국정보처리학회 2020 Journal of information processing systems Vol.16 No.1

Capsule endoscopy is one of the increasingly demanded diagnostic methods among patients in recent yearsbecause of its ability to observe small intestine difficulties. It is often conducted for 12 to 14 hours, butsignificant frames constitute only 10% of whole frames. Thus, it has been designed to automatically acquiresignificant frames through deep learning. For example, studies to track the position of the capsule (stomach,small intestine, etc.) or to extract lesion-related information (polyps, etc.) have been conducted. However,although grouping or labeling the training images according to similar features can improve the performanceof a learning model, various attributes (such as degree of wrinkles, presence of valves, etc.) are not consideredin conventional approaches. Therefore, we propose a class-labeling method that can be used to design a learningmodel by constructing a knowledge model focused on main lesions defined in standard terminologies forcapsule endoscopy (minimal standard terminology, capsule endoscopy structured terminology). This methodenables the designing of a systematic learning model by labeling detailed classes through differentiation ofsimilar characteristics.

The urease is covalently immobilized on the surface of the magnetic particles to catalyze the conversion of urea to bicarbonate anion. The conversion was confirmed qualitatively using high-pressure liquid chromatography and UV/Vis spectrometry, and analyzed quantitatively with cyclic voltammetry. The amount of conversion with respect to time was measured and analyzed by the reaction rate equation to calculate a reaction rate constant of 0.0474 min-1. In the 1 to 3 cycles, a conversion percentage of over 90% was found, and it was possible to reuse the urease 8 times up to the percentage of 50%. It was also observed that the stability evaluated for storage for 30 days was maintained. As a result of this study, it can be seen that the urease covalently immobilized on the scaffold can be used for urea removal for the purpose of producing ultrapure water.

2세 여아에서 성장 부진과 다리 통증을 동반한 1형 고셔병 증례

고셔병은 리소좀축적병으로 lysosomal hydrolase glucocerebrosidase 결여로 간비장비대, 골격계 증상, 빈혈, 혈소판 감소증의 증상을 나타내는 드문 상염색체 유전 질환이다. 본 증례에서는 2세 여아에서 간비장비대, 다리 통증, 성장부진이 관찰되어 시행한 단순 방사선 촬영 검사에 Erlenmeyer flask 변형을 확인하여 고셔병을 의심하였고 효소 분석 및 유전자 검사를 통해 확진하였다. 환아에서 한국인 비신경형 고셔병에서만 관찰되는 G46E 돌연변이를 확인하였고 1년 간의 효소 대체 요법을 통해 성장, 혈액학적 지표, 간비장비대 및 골증상의 호전을 확인하였기에 본 증례를 보고하는 바이다. Gaucher disease (GD) is caused by the deficiency of glucocerebrosidase. In pediatric patients with GD, especially Type I GD, enzyme replacement therapy (ERT) can reduce the hepatosplenomegaly and improve the hematologic finding and growth velocity. Herein, we report a 2-year-old girl with Type I GD presented with hepatosplenomegaly, bone pain and growth retardation. A 2 year-old-girl was referred to our hospital due to severe hepatosplenomegaly and growth retardation. She suffered from both leg pain and chronic fatigue. Simple x-ray showed widened distal long bones like that of an 'Erlenmeyer flask' which is associated with GD. The laboratory test showed anemia and thrombocytopenia. The enzyme activity was markedly reduced and the direct sequencing of the GBA gene showed the compound heterozygous mutations, p.G46E and p.L444P. As the G46E have been considered as the protective gene against neuronopathic genotype, we could assess the Type I GD in this patient. After one year of ERT, the growth velocity became 11 cm per year. Bone pain and fatigue disappeared. The volume of liver and spleen was reduced from $683cm^3$ and $703cm^3$ to $590cm^3$ and $235cm^3$, respectively. Although GD is an extremely rare disease in Korea, growth retardation and bone pain in children are the important signs which lead to early detection of GD and a simple radiologic finding is helpful to assess the GD at outpatient clinic. We highlight that the early diagnosis and early ERT is important for good growth and outcome for pediatric patients with GD.

Effect of fuel composition of LNG on the performances and operating characteristics of a gas turbine cycle

박예슬,박새미,최민성,이중성,최경민 대한기계학회 2019 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.33 No.7

The effect of natural gas compositions on the thermodynamic performance characteristics of the single-shaft gas turbine cycle is analyzed in this study. The fuel characteristics are signified by H/C ratio and heating value, then the system are analyzed, and the full off-design analysis is performed by using TIT, TET, and power control. As the heating value of natural gas decreases, power output increases due to the increased mass flow passing through the turbine for all control methods. Additionally, regardless of the control method, the compressor surge margin is reduced and the turbine blade temperature is raised, making the gas turbine operation extremely vulnerable. Most parameters are sensitively affected by the HC ratio of fuel with TIT control. When the power control is used, gas turbine efficiency is reduced due to the increased operation of the compressor. The results are expressed by polynomial equations relative to each design value. In terms of the performance curves of the gas turbine cycle, the trends of most parameters accord with high H/C ratio and low heating value.

가정환경 변인이 영어 초기문식성에 미치는 영향에 관한 질적 메타 분석

박예슬,김정렬 한국언어과학회 2015 언어과학 Vol.22 No.3

The purpose of this study is to investigate how family background factors such as parents' academic level, income level, and home literacy environment, influence the children's early literacy in English. For this purpose, the qualitative meta analysis was conducted by synthesizing the results of previous studies. The subjects of this study were 12 researches from 1996 to 2014. The first finding of this study is higher parents' academic level tends to lead the children to a better achievement in English literacy. Second, with the parents' higher income level, the children tend to gain a better mean score in English literacy. Third, creating literacy environment had a direct positive effect on children's English literacy ability. However, affective support didn't have a significant effect on literacy development on the contrary to our expectation. The overall children's English literacy development was positively correlated with parents factors and home environments.

출산은 “노동”인가, “행위”인가?—버지니아 울프의 「어느 단체」 속 출산의 정치화와 여성의 정치행위를 중심으로

박예슬 한국근대영미소설학회 2022 근대 영미소설 Vol.29 No.2

Childbearing has been thought of as one of the inevitable and essential human activities. Despite advancements in various areas such as philosophy, science, and technology, the need to procreate has remained an inherent human instinct. According to Hannah Arendt, who defines the three categories of basic human activities as “labor,” “work,” and “action,” procreation belongs to that of “labor” in the way it satiates the basic human needs of humans as animals. However, Foucault’s notion of biopolitics revises and broadens the definition of procreation as “labor”; it is not done as a result of an individual desire but rather biopolitics for a government to expand and maintain its power. Although Virginia Woolf did not use the exact term, she was acutely aware of how biopower operates, as evident in her works such as Mrs. Dalloway. In her short story “A Society,” she imagines what could happen if women realize who has forced them to bear children and how much political power childbearing has. She actively thinks about the possibility of altering procreation from “labor” coerced by “biopolitics” to “action” to fight against the patriarchal society. Although this possibility does not turn out successfully in the narrative, it leaves hope for the next generation. .
