The purpose of this study is to investigate the factors that affect the social distance between the demented elderly and nursing college students. In this study, responses from 158 nursing college students in city D were collected using structured questionnaires and analyzed. As a result, the correlation between variables, social distance, and dementia attitude towards the demented elderly (r = .53, p<.001) showed a statistically correlated relationship, while ageism (r = -. 41, p<.001) showed a negative correlation. The results of this study are as follows: first, the interactions between the elderly with dementia and the nursing college students were more frequent (β = .29 p=.012), and second, attention to early prevention of dementia (β = .32 p=.002) was significant. The explanatory power of these influential factors on the social distance toward the demented elderly was 41.0%. 2017년 우리나라는 고령사회에 진입하면서 치매환자가 증가하고 있다. 이에 추후, 간호 전문 인력으로 역할을 수행하게 될 간호대학생의 치매노인에 대한 관심이 필요하다. 본 연구의 목적은 간호대학생의 치매노인에 대한 사회적 거리감에 미치는 영향요인을 알아보기 위함이다. 본 연구는 서술적 조사연구 연구로, 자료 수집을 위해 D시의 일개 간호대학 158명을 대상으로 구조화된 설문지를 통해 자료를 수집하여 분석하였다. 각 변수간의 상관관계를 분석한 결과 치매노인에 대한 사회적 거리감과 치매태도(r=.53, p<.001)는 정적인 상관관계를 보였으며, 연령주의(r=-.41, p<.001)는 부적상관관계가 있는 것으로 나타났다. 간호대학생의 치매노인의 사회적 거리감에 미치는 영향요인으로는 치매환자와의 소통경험에서 ‘전혀 없다’ 에 비해 ‘가끔 있다’ 와 (β=.29 p=.012), ‘자주 있다’ (β=.37 p=.002)가 영향요인으로 나타났고, 치매조기예방에 대한 관심(β=.32 p=.002), 연령주의(β=.36 p=.002)가 유의한 영향을 미치는 것으로 나타났다. 이러한 영향요인 변수들의 치매노인에 대한 사회적 거리감에 대한 설명력은 41.0% 이었다.

핸드 트래킹을 활용한 비접촉식 인터페이스 기반 VR 콘텐츠 개발- 인체치료게임 <Robot Doctor VR>

김두리,이다연,나정조 한국영상학회 2022 한국영상학회 논문집 Vol.20 No.1

While VR content is gaining in popularity as a result of the COVID-19 epidemic, the demand for VR material has also grown. Nevertheless, the amount of diverse content available to satisfy users is insufficient. In this paper, we planned and developed gesture-based content to pique users' interest in virtual reality and to demonstrate the range of VR content. The industry is currently generating gesture-based content in response to the growing need for new types of content. Meta Oculus incorporates gesture recognition technology into its virtual reality headsets and promotes gesture-based content on its website. We developed and implemented features in this study that enable the generation and execution of content using a gesture-based interface. The device was made utilizing the Oculus Quest2 gesture recognition technology and the Unity game engine. C# and JSON were used as the major programming languages, and modeling and texturing were carried out using Autodesk's 3ds MAX and Blender. 'Robot Doctor VR' is a virtual reality game in which the user manipulates the organs of the human body with their own hands while wearing a head-mounted display. With conversion into a nanorobot, the process of assessing and repairing damaged organs in the human body will be gamified, providing users with an entirely new experience. 'Robot Doctor VR,' which was created to boost user immersion and present new material, aims to develop more realistic graphic content in the future to enable investigations of a wider variety of human organs. Additionally, moving to multiplayer via gesture detection will result in increased content diversity through user participation. 코로나19로 인해 VR 콘텐츠가 주목받고 있는 가운데 VR 콘텐츠의 수요는 증가하였으나, 사용자들을 만족시킬 만한 다양한 콘텐츠의 제작은 부족한 상황이다. 본 논문에서는 VR 콘텐츠의 다양성과 사용자들의 호기심 충족을 위한 제스처 기반의 콘텐츠를 기획, 개발하였다. 새로운 형식의 콘텐츠를 찾는 사용자가 증가하게 되면서 산업계에서도 제스처 인식을 기반으로 하는 콘텐츠를 선보이고 있다. Meta Oculus에서는 제스처 인식 기술을 VR 기기에 탑재하였으며 이를 활용하는 콘텐츠들을 웹사이트에 적극적으로 소개하고 있다. 본 논문에서는 제스처 기반 인터페이스를 사용하여 콘텐츠를 제작하고, 수행할 수 있는 기능들을 설계하고 개발하였다. 디바이스는 제스처 인식 기술이 제공되는 Oculus Quest2를 이용하여 개발을 진행하였으며, Unity 게임엔진을 기반으로 콘텐츠를 제작하였다. 주언어로는 C#, JSON을 사용했으며, Autodesk 사의 3ds MAX, Blender를 사용하여 모델링 및 텍스처링을 진행했다. ‘Robot Doctor VR'은 HMD를 착용한 사용자가 자신의 손으로 직접 조작하며 인체의 기관을 치료하는 게임이다. 나노로봇이 되어 인체 내에서 병에 걸린 장기들의 모습을 살펴보고 치료하는 과정을 게임화하여 사용자들에게 새로운 경험을 제공할 것이다. 사용자의 몰입감 증진과 새로운 콘텐츠의 제시로 개발된 ‘Robot Doctor VR’은 추후 더욱 다양한 신체기관의 탐색을 위하여 현실감 높은 그래픽 콘텐츠의 개발을 목표로 하고 있다. 또한 다양한 제스처 인식을 통한 멀티플레이어로의 확장은 유저들 간의 협업을 통한 콘텐츠의 다양화를 가져오리라 생각한다.

김두리,Zhirayr Baghdasartan,이기진 한국물리학회 2019 새물리 Vol.69 No.12

In this study, pentacene thin films of various thicknesses were fabricated by using the thermal evaporation method, and the phase change, surface morphology and electrical characteristics of these films were analyzed. As the pentacene thin film became thicker, the orthorhombic phase, the thin-film phase, and the bulk phase appeared, in that order, in the measured X-ray diffraction patterns. Also, the roughness was found to change with the phase, as confirmed through atomic force microscopy (AFM). A pentacene-based diode was fabricated, and the threshold voltage and mobility were measured. When the orthorhombic phase was dominant, the diode’s threshold voltage and mobility were 3.14 V and 3.64 10 7 cm2/ Vs, respectively, and when the thin-film phase was dominant, those results were 1.50 V and 5:08 10 5 cm2/ Vs. When the bulk phase began to appear, the threshold voltage and mobility of the diode were 2.80 V and 6:75 10 5 cm2/Vs. In this way, we were able to observe the dependenced of the electrical properties on the properties of the phase. 본 연구는 열 증착 방법을 통해 여러 두께의 펜타센 (pentacene)박막을 제작하여 상 변화, 표면 모폴로지(morphology)와 소자의 전기적 특성을 분석하였다. 펜타센 박막이 두꺼워질수록 orthorhombic phase, thin film phase, bulk phase가 차례대로 나타나는 것을 X-ray diffraction 측정 결과로 확인하였다. 또한 상변화에 따른 거칠기를 AFM을 통해서 확인하였다. 펜타센 기반 다이오드를 제작하여 문턱 전압, 이동도를 측정하였다. orthorhombic phase가 우세할 때 다이오드의 문턱 전압과 이동도는 3.14 V, 3.64 10 7 cm2/ Vs, thin film phase가 우세할 때는 각각 1.50 V, 5:08 10 5 cm2/ Vs였다. bulk phase 가 나타나기 시작할 때는 각각 2.80 V, 6:75 10 5 cm2/Vs였다. 이를 통해 특정한 상의 성질을 나타낼때의 전기적 특성을 관측하였다.

Comparison of Three, Motion-Resistant MR Sequences on Hepatobiliary Phase for Gadoxetic Acid (Gd-EOB-DTPA)- Enhanced MR Imaging of the Liver

김두리,이정섭,최국명,김승형,고명주,송병철,이무숙,이경렬,고수연,김봉수 대한자기공명의과학회 2017 Investigative Magnetic Resonance Imaging Vol.21 No.2

Purpose: To compare three, motion-resistant, T1-weighted MR sequences on the hepatobiliary phase for gadoxetic acid-enhanced MR imaging of the liver. Materials and Methods: In this retrospective study, 79 patients underwent gadoxetic acid-enhanced, 3T liver MR imaging. Fifty-nine were examined using a standard protocol, and 20 were examined using a motion-resistant protocol. During the hepatocyte-specific phase, three MR sequences were acquired: 1) gradient recalled echo (GRE) with controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA); 2) radial GRE with the interleaved angle-bisection scheme (ILAB); and 3) radial GRE with golden-angle scheme (GA). Two readers independently assessed images with motion artifacts, streaking artifacts, liver-edge sharpness, hepatic vessel clarity, lesion conspicuity, and overall image quality, using a 5-point scale. The images were assessed by measurement of liver signal-to-noise ratio (SNR), and tumor-toliver contrast-to-noise ratio (CNR). The results were compared, using repeated posthoc, paired t-tests with Bonferroni correction and the Wilcoxon signed rank test with Bonferroni correction. Results: In the qualitative analysis of cooperative patients, the results for CAIPIRINHA had significantly higher ratings for streak artifacts, liver-edge sharpness, hepatic vessel clarity, and overall image quality as compared to, radial GRE, (P < 0.016). In the imaging of uncooperative patients, higher scores were recorded for ILAB and GA with respect to all of the qualitative assessments, except for streak artifact, compared with CAIPIRINHA (P < 0.016). However, no significant differences were found between ILAB and GA. For quantitative analysis in uncooperative patients, the mean liver SNR and lesion-to-liver CNR with radial GRE were significantly higher than those of CAIPIRINHA (P < 0.016). Conclusion: In uncooperative patients, the use of the radial GRE sequence can improve the image quality compared to GRE imaging with CAIPIRINHA, despite the data acquisition methods used. The GRE imaging with CAIPIRINHA is applicable for patients without breath-holding difficulties.

횔링크스로 읽는 베케트 문학의 대칭성 - 소설 『머피Murphy』와 희곡 『고도를 기다리며En attendant Godot』를 중심으로

김두리 한국프랑스학회 2019 한국프랑스학논집 Vol.107 No.-

Cette étude a pour but d’analyser la symétrie des œuvres littéraires de Samuel Beckett autour de son roman Murphy (1938) et de sa pièce de théâtre En attendant Godot (1952). Selon Katharine Wort, « tout est symétrique et tend à arriver en double » dans la structure d’En attendant Godot. En effet, la symétrie est omniprésente dans l’univers littéraire de Beckett non seulement sur le plan des structures textuelles mais aussi sur le plan du langage et du comportement des personnages. Beckett a dit : « si vous voulez trouver les origines d’En attendant Godot, regardez Murphy. » Murphy est un personnage éponyme qui « se sentait fendu en deux, d’un côté un corps, de l’autre côté un esprit ». Étant donné que Murphy a reçu de l’influence du philosophe « post-cartésien » Arnold Geulincx, on vise d’abord à trouver des implications de sa théorie occasionnaliste et ensuite à vérifier la relation entre la structure symétrique du texte et sa philosophie. Enfin autour d’En attendant Godot, on vise à confirmer des effets engendrés par la symétrie des deux actes et du mime des deux protagonistes Estragon et Vladimir en recourant à leurs chapeaux. Beckett a mis dans sa tragicomédie des magnifiques scènes symétriques qui créent un effet grotesque. La symétrie du texte beckettien commence par le dédoublement entre le corps et l’esprit (Murphy) ou entre l’ego et l’alter ego (Estragon et Vladimir). Et elle représente d’un côté le cycle, la répétition, l’éternité et de l’autre côté le système fermé, la stagnation de la situation et du temps. Elle reflète donc la conscience du monde de Beckett. Dans le roman Murphy, il y a un jeu d'échec entre Murphy et M. Endon, un « petit gaga » de la Maison Madeleine de Miséricorde Mentale (M.M.M.M). M. Endon qui s’était replié sur lui-même a joué aux échecs pour obtenir sans relâche une position symétrique. Murphy n’a pu être perçu par M. Endon. Et Murphy qui imitait dans un premier temps les symétries successives de M. Endon a fini par abandonner la partie d’échecs, après avoir réalisé l’impossible imitation des coups de son adversaire : il concrétise l’axiome de Geulincx ubi nihil vales ibi nihil velis (“wherein you have no power, therein neither should you will” traduit par Beckett). Beckett était adepte du jeu d’échecs et l’échec est un de ses motifs répétitifs pour représenter l’existence limitée de l’homme. De plus Beckett considérait la scène comme un échiquier. En résultat, la symétrie du texte beckettien montre sa poétique de « form is content, content is form » et puis dans l’univers littéraire de Beckett qui écrivait en français et traduisait en anglais lui-même ou à l’inverse jusqu’à la fin de sa vie, incarne le mouvement « keep ! for end » que Beckett a écrit comme une sorte de testament au-dessus de son autographe du poème anglais what is the word (1989).

Effect of Having a Usual Source of Care on Medical Expenses – Using the Korea Health Panel Data

김두리,김솔잎,박혜경,하인혁,정보영,류원형,이상일,성낙진 대한의학회 2019 Journal of Korean medical science Vol.34 No.35

Background: There is a controversy about the effect of having a usual source of care on medical expenses. Although many studies have shown lower medical expenses in a group with a usual source of care, some have shown higher medical expenses in such a group. This study aimed to empirically demonstrate the effect of having a usual source of care on medical expenses. Methods: The participants included those aged 20 years and older who responded to the questionnaire about “having a usual source of care” from the Korean Health Panel Data of 2012, 2013, and 2016 (6,120; 6,593; and 7,598 respectively). Those who responded with “I do not get sick easily” or “I rarely visit medical institutions” as the reasons for not having a usual source of care were excluded. The panel regression with random effects model was performed to analyze the effect of having a usual source of care on medical expenses. Results: The group having a usual source of care spent 20% less on inpatient expenses and 25% less on clinic expenses than the group without a usual source of care. Particularly, the group having a clinic-level usual source of care spent 12% less on total medical expenses, 9% less on outpatient expenses, 35% less on inpatient expenses, and 74% less on hospital expenses, but 29% more on clinic expenses than the group without a usual source of care. Conclusion: This study confirmed that medical expenses decreased in the group with a usual source of care, especially a clinic-level usual source of care (USC), than in the group without a usual source of care. Encouraging people to have a clinic-level USC can control excessive medical expenses and induce desirable medical care utilization.

Increasing life expectancy has increased interest in the quality of life of the elderly population. The need for customized care has recently been emphasized, and the number of care services utilizing artificial intelligence is increasing. Therefore, this study was undertaken to explore and analyze research trends in age-related artificial intelligence and to present implications of the use of artificial intelligence on care of the elderly. Text network analysis was used to search the domestic academic literature for the keywords 'elderly' and 'artificial intelligence'. Forty-three academic papers were selected for final analysis. Main core analysis was performed using network text analysis, connection centrality index calculations, and community cohesion analysis. The study shows the keywords for research on artificial intelligence related to the elderly were 'care service', 'digital', 'artificial intelligence speaker', and 'robot'. Three cohesive structures, namely, research related to digital education, research related to digital elderly welfare, and research on care services related to robots and artificial intelligence speakers were identified by grouping subjects with high conceptual relationships. The results of this study suggest that intervention studies related to digital education and various studies related to the use of artificial intelligence in elderly care services will be needed in the future.
