박정은,양동욱,김하영,Park, Jeongeun,Yang, Dong-Uk,Kim, Ha-Young 한국융합학회 2021 한국융합학회논문지 Vol.12 No.7

인공지능 스피커 시장은 꾸준히 성장하고 있지만, 실제 스피커 사용자들의 만족도는 42%에 그치고 있다. 따라서, 본 연구에서는 인공지능 스피커의 세대별 토픽 변화와 감성 변화를 통해 사용자 경험을 저해하는 요소는 무엇인지 분석해 보고자 한다. 이를 위해 아마존 에코 닷 3세대와 4세대 모델에 대한 리뷰를 수집하였다. 토픽모델링 분석 기법을 사용하여 세대별로 리뷰를 이루는 주제 및 주제의 변화를 찾아내고, 딥러닝 기반 감성 분석을 통해 토픽에 대한 사용자 감성이 세대에 따라 어떻게 변화되었는지 살펴보았다. 토픽모델링 결과, 세대별로 5개의 토픽이 도출되었다. 3세대의 경우 스피커의 일반적 속성을 나타내는 토픽은 제품에 긍정적 반응 요인으로 작용했고, 사용자 편의 기능은 부정적 반응 요인으로 작용했다. 반대로 4세대에서는 일반적 속성은 부정적으로, 사용자 편의 기능은 긍정적으로 도출되었다. 이와 같은 분석은 방법론 측면에서 어휘적 특징뿐 아니라 문장 전체의 문맥적 특징이 고려된 분석결과를 제시할 수 있다는 것에 그 의의가 있다. The AI speaker market is growing steadily. However, the satisfaction of actual users is only 42%. Therefore, in this paper, we collected reviews on Amazon Echo Dot 3rd and 4th generation models to analyze what hinders the user experience through the topic changes and emotional changes of each generation of AI speakers. By using topic modeling analysis techniques, we found changes in topics and topics that make up reviews for each generation, and examined how user sentiment on topics changed according to generation through deep learning-based sentiment analysis. As a result of topic modeling, five topics were derived for each generation. In the case of the 3rd generation, the topic representing general features of the speaker acted as a positive factor for the product, while user convenience features acted as negative factor. Conversely, in the 4^th generation, general features were negatively, and convenience features were positively derived. This analysis is significant in that it can present analysis results that take into account not only lexical features but also contextual features of the entire sentence in terms of methodology.

Psychometric Evaluation of the Korean Version of the Student Evidence-Based Practice Questionnaire (S-EBPQ)

박정은,황지인 한국간호과학회 2021 Asian Nursing Research Vol.15 No.1

Purpose: Evidence-based practice (EBP) is a key competency that undergraduate nursing students need to learn, as EBP competence is essential for the effective implementation of EBP. However, few studies have comprehensively assessed the aspects of EBP competence using a reliable and valid measure specific to Korean nursing students. This study aimed to translate the Student Evidence-Based Practice Questionnaire (S-EBPQ) into Korean and evaluate its psychometric properties. Methods: The original S-EBPQ was translated into Korean. After a pilot test, a convenience sample of 249 college students with more than four weeks of clinical training experience was selected from three universities in September 2017. Reliability and construct validity were evaluated using exploratory and confirmatory factor analyses. Concurrent validity was evaluated by correlating the measure with informatics competency. Results: The exploratory factor analysis revealed four factors that explained 66.3 of the variance. The confirmatory factor analysis yielded a 4-factor structure (c2/df = 1.52, p < .001, standardized root-meansquare residual = .07, root-mean-square error of approximation = .07, goodness of fit index = .84, comparative fit index = .91). The Cronbach’s a was .81 for the total scale. The scale’s correlation with informatics competency was r = .55. Conclusions: The Korean S-EBPQ is a reliable and valid tool that has utility for assessing EBP competence in Korean nursing students and for making comparisons of the EBP competence of nursing students from other countries.

브로카 실어증 환자의 의문문 이해

박정은,최예린 한국장애인재활협회 2011 재활복지 Vol.15 No.2

This study examined the necessary cues they relied on to understand interrogative sentences when the group with Broca's aphasia and the normal group understood interrogative sentences requiring postposition cues which were grammatical information and interrogative cues which were semantic information, and understanding difference according to the types of interrogative sentences. For this study Auditory comprehension task was used for understand in wh-questions. the result of study is First, the difference in understand in of th group with Broca's aphasia was not statistically significant according to cue conditions, but the normal group used more postposition cues than interrogative cues. Second, The patients with Broca's aphasia had a greater performance in subjective questions than objective questions. in conclusion is The group with Broca's ahpasia had difficulties in using grammatical cues and semantic cues of interrogative sentence, but they can use postposition cues restrictively when they understand wh-questions. 브로카 실어증군과 정상군이 문법적 정보인 조사단서와 의미적 정보인 의문사단서의 처리가 요구되어지는 의문문을 이해할 때 어떠한 단서에 의존하여 의문문을 이해하는지 알아보고 의문문의 종류에 따라 이해 능력에 차이가 있는지 알아보았다. 이를 위해 의문문을 듣고 이해하여 그림 내 대상을 가리키는 청각적 이해 과제를 사용하였다. 본 연구 결과는 다음과 같다. 첫째, 브로카 실어증군은 단서조건에 따라 의문문 이해 능력의 차이가 없었으나 정상군은 의문사 단서에 비해 조사단서를 더 활용하는 경향을 보였다. 둘째, 브로카 실어증군은 정상 성인군과 비교하여 의문문의 종류별 이해능력이 현저히 부족하지만 정상 성인과 마찬가지로 목적격 질문에 비해 주격 질문에 대한 수행력이 더 높은 것으로 나타났다. 이상을 종합해볼때 브로카 실어증군은 의문문의 문법적 단서와 의미적 단서를 활용하는 데 결함이 있으나 의문문을 이해할 때 제한적으로 조사단서를 활용한다고 볼 수 있다.

박정은,이미현,Seungyun Shin 국민체육진흥공단 한국스포츠정책과학원 2015 International Journal of Applied Sports Sciences Vol.27 No.2

The purpose of this study is to verify the accuracy of energy consumption per wearing location (waist, wrist, ankle) of uniaxial accelerometer (GT1M) during horse-riding exercise (normal-walking, fast-walking, running). The study subjects were conveniently sampled from 11 males in their 20s from S horse-riding course who have over 3 years of experience in horse-riding and are licensed as leisure sports instructors (horse-riding), and the following conclusion was drawn. For normal-walking, there was no significant difference of standard energy consumption among waist, wrist, and ankle, and all three locations showed confidence interval with small deviation in Bland-Altman Plot. On the other hand, for fast-walking and running, only wrist showed no significant difference, where only wrist location showed low-deviation confidence interval in Bland-Altman Plot. According to such results, the accuracy was relatively high for wrist-wearing when predicting horse-riding activity energy consumption using accelerometer. Therefore, the wearing location must be considered when predicting horse-riding activity energy consumption with accelerometer on site.

This study was conducted to identify factors affecting patient safety management (PSM) of nursing student’s who have experienced clinical practice. The study subjects were 232 nursing students in five universities in five cities. Data were collected between June 17 and July 30, 2019 using by completing structured self report questionnaires. Data were analyzed using T-test, ANOVA, Pearson‘s correlation coefficient, and multiple regression using SPSS/WIN 22.0. In correlation analysis, significant positive correlations were found between PSM practice, PSM importance awareness(r= .42, p<.001), PSM knowledge(r= .29, p<.001), and PSM attitude(r= .35, p<.001). In multiple regression analysis, PSM importance awareness(β=.19, p<.001) was factor predicting PSM practice of nursing students, which explained 36.2% of the variance in the model. Thus, we emphasize that continuing PSM education at the university is required to improve PSM competency. 본 연구는 임상실습을 경험한 간호학생들의 환자안전관리 실천에 영향을 미치는 요인을 분석하기 위해 수행하였다. 연구대상자는 국내 5개 도시의 5개 대학에 재학 중인 간호학생 232명이었다. 자료수집은 2019년 6월 17일부터 7월 30일까지 시행되었고, 구조화된 자가보고식 설문지 작성을 통해 수집하였다. 자료분석은 SPSS 22.0 windows program을 이용하여, T-test, ANOVA, Pearson‘s correlation coefficient, multiple regression을 이용하였다. 상관분석 결과, 환자안전관리 실천은 환자안전관리 중요성 인식(r= .42, p<.001), 지식(r= .29, p<.001), 태도(r= .35, p<.001)와 유의한 양의 상관관계가 있었다. 다중회귀분석 결과, 환자안전관리 중요성 인식은 환자안전관리 실천에 유의한 영향(β=.19, p<.001)을 미치는 것으로 확인되었으며, 모형의 설명력은 36.2%였다. 이에 본 연구에서는 간호학생들의 환자안전관리 역량을 개선시킬 수 있는 대학단위의 교육이 꾸준하게 이루어질 필요가 있음을 강조한다.
