This study examined the perception and production of Korean lax, fortis and aspirated stops in three apraxic patients. All of tile subjects made more production errors than perception errors. This indicates that apraxic patients have problems in phonetic execution rather than phonological representation. Additionally, in both production and perception, there were more errors in non-word-initial consonants than in word-initial consonants. These findings contradict those of the previous studies which report more errors in word-initial consonants. This study also found that, unlike previous studies in the types of errors made, distortion errors were high in both non-word-initial and word-initial consonants in apraxic patients. Generally, VOT of the stops showed significant differences among lax, fortis, and aspirated stops, which indicates that there is a failure not in choosing the appropriate stop but in positioning or motor planning at the articulation stage.

김수정,이시우,이영섭,Kim, Sujung,Lee, Siwoo,Lee, Youngseop 대한예방한의학회 2017 대한예방한의학회지 Vol.21 No.1

Objectives : In this study, we diagnosed Mibyeong group of adult by taking into Mibyeong Index consideration, and identified the correlation of a Mibyeong group with cold-heat pattern and life quality of them. Methods : The questionnaires were collected by Gallup Korea professional surveyor through face to face interviews. To analyze the differences between health and mibyeong group, we used the descriptive statistics, Pearson's correlation, ANOVA. And multinomial logistic regression was used to generate the odds ratios (ORs) and 95 % confidence interval (CI) for the differences between health and mibyeong group. Results and Conclusions : The gender composition of respondents in this study that there 545 male (49.5%) and 555 female (50.5%). The score of both cold pattern(health: $21.33{\pm}4.25$, MI 1: $22.43{\pm}4.29$, MI 2: $24.09{\pm}5.03$; post hoc test, p <0.001) and heat pattern(health: $18.4{\pm}4.01$, MI 1: $19.48{\pm}4.10$ MI 2: $19.88{\pm}4.81$; post hoc test, p <0.001) in mibyeong group is higher than the score health group. And, these result have no relevance to age. The score of both Physical component summary (PCS) and Mental component summary (MCS) in health group is higher than the score mibyeong group. Cold-heat pattern and quality of life vary significantly according to health status. This results suggest the analysis of cold-heat pattern and quality of life by health status could provide the setting of direction to promote public health depending on health status.

공간이웃정보를 고려한 공간회귀분석

김수정,Kim, Sujung 한국데이터정보과학회 2017 한국데이터정보과학회지 Vol.28 No.3

최근, 더욱 상세하고 정확한 추정 결과를 위해 소지역추정(small area estimation; SAE)의 연구가 많이 진행되고 있다. 그 중 공간회귀모형 (spatial regression model)을 이용한 방법이 주를 이루고 있는데 이를 사용하기 위해서는 공간이웃 (spatial neighbor)의 정의가 필요하다. 본 연구에서는 공간이웃을 정의하는 방법으로 도로네 삼각망 (Delaunay triangulation; DT)을 소개하고 k-최근접 (k-nearest neighbor; KNN)과 비교하여 분석한다. 두 가지 공간이웃을 정의하는 방법중에서 어떤 방법으로 이웃을 정의하는 것이 효율적인지 알아보기 위해 시뮬레이션을 실시하였고, 지가 (land price)데이터를 이용하여 실 데이터를 분석하였다. Recently, numerous small area estimation studies have been conducted to obtain more detailed and accurate estimation results. Most of these studies have employed spatial regression models, which require a clear definition of spatial neighborhoods. In this study, we introduce the Delaunay triangulation as a method to define spatial neighborhood, and compare this method with the k-nearest neighbor method. A simulation was conducted to determine which of the two methods is more efficient in defining spatial neighborhood, and we demonstrate the performance of the proposed method using a land price data.

한국어 학습자를 위한 과거시제 관형사형 어미 교육 연구 - `-(으)ㄴ, -던, -았던`을 중심으로

김수정 ( Kim Sujung ),박덕유 ( Park Deokyu ) 인하대학교 교육연구소 2017 교육문화연구 Vol.23 No.1

과거시제 관형사형 어미는 한국어 학습자들이 복합문을 만들기 위해 초급에서부터 배우는 문법 항목이다. 그럼에도 불구하고 고급 이상의 한국어 학습자들도 과거시제 관형사형 어미의 사용을 어려워하는 이유는 각 어미 간의 차이점뿐만 아니라 유사성이 존재하기 때문이다. 이에 본고는 과거시제 관형사형 어미의 의미 기능들 간의 유사성과 차이점을 알아보고, 과거시제 관형사형 어미에 대한 효율적인 교수 방안을 제시하는 데 그 목적이 있다. 이를 위해 먼저 기존 연구와 한국어 교재 분석을 통해 과거시제 관형사형 어미의 의미 기능 간의 유사성 및 차이점 등을 기술하였다. 또한 학습자들의 작문과 설문 조사 및 인터뷰, 그리고 한국인 모어 화자의 설문조사를 통해 과거시제 관형사형 어미의 사용 양상을 고찰하였다. 마지막으로 이러한 결과와 연구자의 실제 교수 학습 경험을 토대로 과거시제 관형사형 어미의 의미 기능에 따른 7단계 교수학습 내용을 선정하여 제시하였다. The past tense adnominal endings are a grammar item that teaches from the beginning level to make compound sentence. Nonetheless, Korean learners in advanced levels also have difficulties in using the past tense adnominal endings, because there are similarities as well as differences between the endings. The purpose of this study is to examine the similarities and differences between the semantic functions of the past tense adnominal endings and to suggest effective teaching methods for those endings. For this purpose, the similarity and difference between the semantic functions of the past tense adnominal endings were described through the analysis of existing research and Korean textbooks. We also examined the use of past tense adnominal endings through the writings practices, questionnaires, interviews of Korean language learners, and questionnaires of Korean native speakers. Finally, based on these results and the actual teaching and learning experiences of the researchers, we selected and presented 7 steps of the teaching contents according to the semantic function of the past tense adnominal endings.

This study delved into the complex nature of medical services as experience goods and trust services, investigating the profound impact of online word-of-mouth on medical consumers' decisions to visit hospitals. Considering the restrictive legal framework for medical advertising, consumers are increasingly dependent on unrestricted sources of information like online reviews. This research aimed to provide empirical evidence for the significant role online word-of-mouth plays in hospital selection. Utilizing data from Naver reviews, hospital choice factors were classified based on the Kano model, revealing the subtle yet significant influence that word-of-mouth has on consumers' hospital visit intentions beyond merely positive or negative messages. In particular, the study provided insights into how the categorized positive and negative information, along with the presence or absence of emotional expression, affects the efficacy of word-of-mouth. The experiment targeted medical consumers aged over 20 and, through analysis using the SPSS statistical program, yielded important findings. The direction of online word-of-mouth, the presence of emotional expression, and the interaction of Kano attributes all created significant differences in hospital visit intentions. Notably, emotional expression included in negative word-of-mouth concerning one-dimensional attributes markedly decreased visit intentions, whereas the absence of emotional expression in attractive attributes actually enhanced reliability and increased visit intentions. These findings offer critical implications for redefining strategies in medical marketing and online review management. The discoveries of this study underscore the importance of active engagement and strategic management of online reviews by medical service providers, urging careful consideration of the various elements of online word-of-mouth that influence medical consumers' hospital visit intentions..

김수정(Kim, Sujung) 한국디자인지식학회 2014 디자인지식저널 Vol.31 No.-

본 연구는 캡션평가법과 감성어휘이라는 환경심리조사수법을 이용하여 대구 근대골목투어 2코스의 시각적 구성요소에서 시각적 관심을 불러일으키는 경관의 구성요소가 무엇이고, 이들 구성요소들에 대한 이미지가 어떻게 받아들여지고 있는 지에 대한 기초적 데이터를 제시하는데 그 목적이 있다. 조사대상자는 대구거주 실내건축디자인학부 전공자들로 전공 재학생들이 각자 카메라를 갖고 자유롭게 코스를 걸으며 좋다·고 생각하는 것을 사진으로 찍고 그 느낌을 감성어휘로 기록하는 현장방문 조사를 하였다. 조사결과는 크게 세 가지로 요약할 수 있다. 첫째, 참가자들은 직접방문지를 촬영하면서 느껴지는 시각 물(대구 ‘근대골목투어 2코스’)에 대하여 ‘이색적이다’, ‘지붕’, ‘벽돌’과 같은 감각적 감성을 어휘로 서술 하였다. 둘째, 좋은 장소로 평가한 곳은 [6. 계산성당]으로 시각적 구성요소인 공간구성과 마감 재료에 대해서 세심한 평가를 하였다. 셋째, 장소구성과 공간 구성요소는 서로 밀접한 상호의존과 상호보안적 관계로 공간의 이미지와 장소에 영향을 미치는 것을 알 수 있었다. This study aims to examine landscape components which draw visual attention among visual components of Daegu"s Modern Alley Tour Course 2 using environmental psychological investigation techniques of caption evaluation method and sensibility vocabulary and to provide basic data on how images about these components are being accepted. The subjects were undergraduates residing in Dague whose major was interior architecture design and an on-site visit survey was conducted where the subjects photographed what they felt liked with a camera freely walking on the Course and recorded their feelings with sensibility vocabulary. The survey results are largely summarized into three points. First, the participants described the visual object (Dague"s Modern Alley Tour Course 2) they felt while photographing the place with sensibility vocabulary like "unusual", "roofs", and "bricks". Second, they evaluated 6. Gyesan Catholic Church as a good place and made detailed assessment about its visual components of space composition and finish materials. Third, place composition and space components had very close interdependent and mutually complementary relationship, affecting space images and places.

Ag 나노입자와 나노홀 배열구조를 이용한 초박형 단결정 Si 태양전지의 광흡수 증진

김수정(Sujung Kim),조윤애(Yunae Cho),손아름(Ahrum Sohn),김동욱(Dong-Wook Kim) 한국태양광발전학회 2016 Current Photovoltaic Research Vol.4 No.2

We investigated the influences of Ag nanoparticle (NP) arrays and surface nanohole (NH) patterns on the optical characteristics of 10-μm-thick c-Si wafers using finite-difference time-domain (FDTD) simulations. In particular, we comparatively studied the plasmonic effects of both monomer arrays (MA) and heptamer arrays (HA) consisting of identical Ag NPs. HA improved the optical absorption of the c-Si wafers in much wider wavelength range than MA, with the help of hybridized plasmon modes. The light trapping capability of the NH array pattern is superior to that of the Ag plasmonic NPs. We also found that the addition of the Ag HA on the wafers with surface NH patterns further enhanced optical absorption: the expected short-circuit current density was as high as 34.96 mA/㎠.

표면 정규 벡터 기반 커널을 이용한 3차원 물체 복원

김수정(Sujung Kim),김욱중(Wook-Joong Kim),김성대(Seong-Dae Kim) 대한전자공학회 2010 대한전자공학회 학술대회 Vol.2010 No.6

본 논문은 2차원 영상들로부터 3차원 물체 복원 시 표면 정규 벡터 힘을 이용하는 방법을 제안한다. 3차원 복원에 사용하는 색상 정합 정보는 3차원 물체 표면에만 존재하고, 불연속적이다. 또한 데이터가 표면에서 일정한 값을 가지지 않는다. 이러한 특징 때문에 3차원 물체 복원은 기존의 2차원 세분화 기법보다 더 섬세한 기법이 요구된다. 3차원 표면의 정보를 표현하고 있는 표면 정규 벡터는 경계면을 실제표면으로 끌어당기는 힘으로 이용될 수 있고, 이는 데이터의 노이즈성분에 의해 국소지점에 빠지거나, 오목한 부분을 제대로 복원하지 못하는 문제를 해결할 수 있다. 실험에서 제안한 표면 정규 벡터 힘에 기반한 커널 사용이 기존 기법들에 비해 우수한 성능을 가짐을 검증한다.
