Recently, flexible displays have been used as part of fashion beyond the concept of parts for electronic products. The flexible display applied to wearable fashion products flexibly bends according to the wearing position of the human body and, at the same time, decorates the fashion product more splendidly through the screen on which images or videos are displayed. Flexible displays, which are used for clothes and accessories, combine analogue fashion sensibility with digital screens to create a new level of convergence product design and expand the range of fashion design and fashion materials. This study aims to analyze the trends of the development and commercialization of fashion products that use flexible displays. As a research method, theoretical research and empirical research through case analysis were conducted in parallel. First, as a theoretical study, the morphological and technical characteristics of flexible displays were examined. Through theoretical studies, the effect of the characteristics of flexible displays on the development of wearable fashion products was investigated. Second, as an empirical case study, the design of wearable fashion products using flexible displays over the past 10 years and the characteristics of the displays used in the products were analyzed. Based on the characteristics analyzed, the product design, display and product integration methods and the commercialization stages of wearable fashion products using flexible displays were analyzed.

In general, when a building fire occurs, the heat flow rises by buoyancy, which affects the temperature rise of the ceiling. In addition, when the ceiling ignites, the fire spreads rapidly due to horizontal spread and radiant heat. According to the fire investigation, most of the large fires have a common characteristic that the fire spreads to the ceiling and causes many casualties. Therefore, it is considered that it is necessary to review the fire risk of ceiling materials used in buildings to prevent the spread of fire to the ceiling. Therefore, in this study, combustion characteristics such as the amount of heat released and ignition time of each SMC, DMC, and gypsum board were checked using a Cone Calorimeter, and the ignition temperature was calculated by substituting them into the fire theory. As a result, the ignition temperature of SMC was 449K, that of DMC was 1492K, and that of gypsum board was 677K.

김혜원 ( Kim¸ Hye Won ),전영석 ( Jhun¸ Youngseok ) 한국초등과학교육학회 2021 초등과학교육 Vol.40 No.3

본 연구의 목적은 LDA 토픽모델링을 활용하여 최근 5년간의 과학영재교육 관련 연구의 동향을 살펴보는 것이다. 보편적으로 이용되는 국내 학술 데이터 RISS, KISS, DBpia를 선정하여 국내 학술논문 292편을 수집해 2,404개의 키워드를 분석하였다. 주요 분석 결과는 다음과 같다. 첫째, 최근 과학영재교육 연구물 수는 2019년에 이르기까지 그 수가 줄어들고 있으며, 과학 영재교육 관련 연구에서 상위 10개의 주제어는 ‘학생’, ‘프로그램’, ‘초등’, ‘수업’, ‘창의성’, ‘영재교육’, ‘인식’, ‘교사’, ‘교육’, ‘활동’으로 나타났다. 둘째, 토픽모델링 분석 결과로는 총 10개의 토픽이 도출되었다. 최근 5년간 과학 영재교육에서 주로 이루어진 연구주제는 ‘과학 영재학생의 정의적 특성’, ‘중등 과학 영재학생의 특성’, ‘과학영재교육 프로그램의 개발 및 적용’, ‘과학고와 과학영재고의 교육활동’, ‘과학 영재학생의 인지적 특성’, ‘과학영재교육 정책’, ‘과학영재학생과 창의성’, ‘과학영재학생들의 연구수행교육’, ‘과학영재학생의 학업과 진로선택’, ‘과학 영재학생의 과학 개념’으로 나타났다. 과거에는 특정 토픽의 비중이 상대적으로 높게 나타났으나, 2019년으로 올수록 토픽 간 비중이 크게 차이가 나지 않는다. 따라서 최근으로 올수록 연구가 한 주제에 치우치지 않고 고루 진행되고 있다는 것을 확인할 수 있었다. The purpose of this study is to examine the trends of science gifted education-related research for the last 5 years using LDA topic modeling. To achieve the purpose of the study, 2,404 keywords of 292 domestic academic papers were analyzed using RISS, KISS, and DBpia. The main results were as follows. First, the number of researches in science gifted education has been decreasing since 2019. In the science gifted education research, the top 10 keywords were ‘students’, ‘program’, ‘elementary school’, ‘class’, ‘creativity’, ‘gifted education’, ‘awareness’, ‘teacher’, ‘education’, and ‘activity’. Second, as a result of topic modeling analysis, 10 topics were derived. Research topics mainly conducted in science gifted education for the past five years are ‘Affective characteristics of science gifted students’, ‘Characteristics of science gifted students in middle school’, ‘Development and application of science gifted education programs’, ‘Education programs of science gifted high school’, ‘Cognitive characteristics of science gifted students’, ‘Policy of science gifted education’, ‘Science gifted students and creativity’, ‘Research conducting education by science gifted students’, ‘Academic and career choice of science gifted students’, ‘Science concept of science gifted Students’. In the past, the proportion of specific topics was relatively high, but the proportion between topics does not differ significantly as 2019 approaches. Therefore, it can be confirmed that the more recent it comes, the more research is being conducted evenly without being biased toward one subject.

텍스트 속에 나타난 분열된 사회 - 체계 기능 언어학적 분석을 중심으로 -

유혜원 ( Yoo¸ Hye-won ) 한민족어문학회 2021 韓民族語文學 Vol.- No.93

이 연구의 목적은 ‘조국 백서’라 불리는 <검찰 개혁과 촛불 시민(2020)>과 ‘조국 흑서’라 불리는 <한번도 경험해 보지 못한 나라(2020)>를 대상으로 텍스트 속에 드러난 분열 양상을 체계 기능 언어학적 분석을 통해 구체화하고자 하는 것이다. 이를 위해 장르적 특성을 분석하고, 이 중에서 ‘언론’을 다루는 부분을 발췌하여 계량적 양상과 질적 양상을 살펴 텍스트에 나타난 분열 양상을 분석하고자 하였다. 그 결과 계량적 분석과 타동성 및 어휘 양상 분석을 통해 <검찰 개혁과 촛불 시민(2020)>의 장르적 특성인 백서의 성격을 확인할 수 있었으며, <한번도 경험해 보지 못한 나라(2020)>에서는 팩트와 논리에 기반하고자 했던 저자들의 의도를 확인할 수 있었다. 또한 <검찰 개혁과 촛불 시민(2020)>에서는 ‘언론’의 문제를 언론 그 자체로 보는 반면, <한번도 경험해 보지 못한 나라(2020)>에서는 ‘언론’이 조작되고 만들어지는 객체라는 인식 등을 확인할 수 있었다. 이러한 분석을 토대로 두 텍스트에 나타난 분열적 양상을 저자, 독자, 내용적 측면에서 제시하였으며, 두 텍스트에 나타난 감정적 어휘의 빈번한 사용, 경멸어의 과도한 사용 등이 우리 사회 분열을 가속화하고 있음을 주장하였다. The purpose of this study was to specify divisive aspects revealed in two texts, < prosecutorial reform and candlelight citizens (2020) > called "ChoKuk white paper" and < country that has never experienced (2020) > called "ChoKuk black paper", through systematic functional linguistic analysis. To this end, genre characteristics were analyzed and division aspects shown in two texts were analyzed by looking at quantitative and qualitative properties. Especially, I analyzed parts that dealt with the 'press' in priority. Results of quantitative analysis, transitivity analysis, and lexical analysis confirmed the nature of the White Paper, a genre characteristic of < prosecutorial reform and candlelight citizens (2020) >, and the authors' intention to base facts and logic in < country that has never experienced (2020) >. In addition, < prosecutorial reform and candlelight citizens (2020) > saw the cause of press problem as the media itself problem, while < country that has never experienced (2020) > revealed the perception that the media could be manipulated and created by the power. Based on this analysis, I presented divisive aspects of the authors, readers, and contentual aspects presented in the two texts, arguing that frequent use of emotional vocabulary and excessive use of pejorative words in both texts are accelerating our social division.

The aim of this study is to explore the differences in the use of disagreement strategies between Korean native speakers(KNS) and Thai Korean learners(TKL) in response to specific types of preceding utterances depending on intimacy and social status. To this end, KNS and TKL were asked to complete a written Discourse-Completion Task(DCT) and their responses were cross analyzed with a multiple response analysis. We found that KNS used various strategies depending on the prior utterance and social variables to ease the burden of disagreement in conversation, however, TKL showed limited use of such strategies. In particular, Korean language learners’ use of disagreement strategies such as ‘declaration’ and ‘silence’ which do not take into account the social context of the individuals in question can lead to misunderstanding among interlocutors. Our research suggests that proper education for expressing disagreement in the classroom is needed to avoid misunderstandings. (Ewha Womans University)

Working Clothes Design and Production in the Mechatronics Machinery Industry with the Application of Faber Birren`s Color Harmony Theory Theory

( Hyewon Hyewon Park ),( Jung Hee Yang ) 한국패션비즈니스학회 2012 패션 비즈니스 Vol.16 No.3

This study proposed a color scheme that is harmonious with the working environment of industrial sites using Birren`s color harmony theory for color planning. To apply the Birren`s color harmony theory to working clothes, the basic colors were chosen, and six of the eight harmony formulas of Birren excluding achromatic colors (white + grey + black) and solid color harmony (solid colors + white + black) were used to form a palette for each case. For the basic colors, the color chips of four dominant colors (yellow-green, sky-blue, blue, and violet), which were chosen from a field survey for preferences in the first step, and the production of materials in the second step were collected through the PANTONE color chips. The selected color chips were PANTONE 13-0550 TPX, PANTONE 15-4105 TPX, PANTONE 18-3949 TPX, and PANTONE 19-3720 TPX. These color chips were scanned and their RGB values were extracted through Photoshop CS. Then the colors were arranged in accordance with the Birren`s color harmony formulas (Color+Tint+White, Color+Shade+Black, Tint+Tone+Shade, Shade+Tone+Black, Shade+Tone+White, and Tint+Shade+Tone+Gray). In addition, the proposed palette color schemes were applied through Birren`s color harmony formulas using Texpro V 10.1 textile to the schematization of working clothes that were designed in the previous study. Palette formation in line with Birren`s color harmony formulas provided scientific color arrangement results. Visually presenting the color scheme of working clothes will help the color selection of working clothes in tune with the circumstances of industrial sites.

Hyewon Woo,Seungbok Lee,Ji Yeon Han,Woo Joong Kim,Man Jin Kim,Moon-Woo Seong,Soo Yeon Kim,Anna Cho,Byung Chan Lim,Ki Joong Kim,Jong-Hee Chae 대한소아신경학회 2022 대한소아신경학회지 Vol.30 No.3

Purpose: X-linked myotubular myopathy (XLMTM) is a rare condition of centronuclear myopathy caused by myotubularin 1 (MTM1) mutations. Patients with XLMTM show different neurodevelopmental outcomes after the neonatal period depending on age and acquired hypoxic damage. We aim to evaluate the clinical characteristics and neurodevelopmental outcomes of patients with XLMTM who were followed up at a single center. It is essential to understand the volume and conditions to prepare for being a candidate for new therapeutic strategies. Methods: Patients diagnosed with centronuclear myopathy by muscle pathology and MTM1 mutation analysis were included. We retrospectively investigated motor milestones, communication skills, and bulbar and respiratory function in the patients. The patients were categorized into two groups: with and without hypoxic insults (HI). Results: All 13 patients were severely affected by neonatal hypotonia and required respiratory support and a feeding tube during the neonatal period. The follow-up duration was 4.4 years (range, 0.3 to 8.9). In the non-HI group, developmental milestones were delayed but were slowly achieved. Some patients underwent training in oral feeding with thickened foods and weaning from ventilation. Patients with HI showed poor motor function catch-up and communication skills. Three deaths were associated with acute respiratory failure. Conclusion: Patients with XLMTM without HI can survive long-term with the slow achievement of motor milestones and bulbar and respiratory function. However, hypoxic brain damage following acute respiratory failure negatively influences their developmental potential or even lead to death. Therefore, parental education for proper respiratory management is necessary, especially for young children.
