Objectives : Dementia has emerged as a leading public health problem in elderly persons, and its early detection is important for the treatment of curable cases, and in the educational support for other family members. Although dementia screening tests are available, they have not gained widespread use in community or primary care settings. Our goal was to validate the Tine and Change (T&C) Test, -including its validity and reliability in patients, and to assess it as a simple, standardized method for the screening of dementia in the rural elderly. Methods : The participants in this study comprised of 59 patients from an urban hospital and 405 persons from a rural community aged 65 years or older. The time test evaluated the understanding of clock hands indicating 11:10, and the change test the ability to make 1,000 Won from a group of coins, consisting of one 500, seven 100, and seven 50 Won coins. The T&C ratings were validated against a reference standard based on the physician's diagnosis of the patients. The convergent validity in relation to other cognitive measure, test-retest agreement, and inter-observer reliability were assessed. To assess the relationship between the Korean Mini-Mental State Exam (K-MMSE) and the T&C Test, the mean K-MMSE scores were compared with the results of the T&C Test in the elderly from a rural community. Results The T&C Test had a sensitivity and specificity of 73.0, and 90.9%, and positive and negative predictive values of 93.1, and 66.7%, respectively. The test-retest and inter-observer agreement rates were both 95%. The K-MMSE scores and T&C Test were significantly related in the elderly from a rural community (p<0.01), The T&C Test was not influenced by the educational status. The Time and Change Tests took a mean of 6.3 and 12.7 seconds, respectively, to complete Conclusion : The T&C Test is a simple, accurate and reliable, performance-based tool in the screening for dementia. Because it is quick, and easy-to-use, it is hoped the T&C Test will be used for the widespread cognitive screening of aging populations.

Granuloma is an uncommon benign disease that develops in the process of wound healing. Pharyngeal or laryngeal granuloma can be associated with gastric reflux, mechanical injury or trauma including intubation, voice abuse, or foreign body. 50-year-old female was transferred to our institute with a huge mass occupying the upper aerodigestive tract causing dysphagia. The patient has been suffering from a brain hemorrhage for several months and was kept in bed due to the quadriplegia with stuporous mental status, and was tracheotomized. On examination, the whole oropharynx and hypopharynx was covered by a smooth-surfaced soft big diffuse granular mass, which extended down to the upper trachea through the larynx. The huge granuloma was successfully removed with surgery and was found to have a pedunculating stalk on the oropharyngeal posterior wall with a small mucosal defect, suggestive of the origin of the mass. The defect was closed primarily after the cauterization. The patient is now followed up regularly without any recurrence of the disease.

정은경,신준호,Jung, Eun-Kyung,Shin, Jun Ho 한국응급구조학회 2021 한국응급구조학회지 Vol.25 No.2

Purpose: This study aimed to develop 360° virtual reality videos and common videos for cardiac arrest recognition. Methods: A sequential mixed methods study was conducted, using qualitative interviews (with a total of seven experts) and a quantitative survey. Results: First, the cardiac arrest situation should be developed within 2-3 minutes after witnessing the patient collapse, for each of the four cardiac arrest videos about apnea, gasping, seizure, gasping, and seizure. Second, the education program should be designed so that the education on cardiac arrest recognition can proceed before CPR practice begins. Conclusion: 360° virtual reality videos and common videos for cardiac arrest recognition can play an important role in the education of the general public about cardiac arrest experience.

정은경,정지연,Jung, Eun-Kyung,Jung, Ji-Yeon 한국응급구조학회 2019 한국응급구조학회지 Vol.23 No.3

Purpose: This study simulates cardiac arrest situations in 360° virtual reality video clips and general video clips, and compares the correlations between educational media and experience recognition. Methods: Experimental research was carried out on a random control group (n=32) and experimental group (n=32) on March 20, 2019. Results: The groups where participants were trained with the 360° virtual reality video clips and a higher score of experience recognition (p=.047) than the group where participants were trained with the general video clips. Moreover, the subfactors of experience recognition including the sense of presence and vividness (p=.05), immersion (p<.05). experience (p<.01), fantasy factor (p<.05). and content satisfaction (p<.05) were positively correlated. Conclusion: Enhancing vividness and the sense of presence when developing virtual reality videos recorded with a 360° camera is thought to enable experience recognition without any direct interaction.

정은경(Eun Kyung Jung),신준호(Jun Ho Shin) 위기관리 이론과 실천 2014 Crisisonomy Vol.10 No.1

본 연구는 2010년 1월 1일부터 2011년 12월 31일까지 119구급대를 통해 병원으로 이송된 제세동 가능한 심실세동, 무맥성 심실빈맥 심전도 리듬을 보이는 심정지 환자 222명을 병원 도착 전 자발순환회복에 미치는 영향을 분석하였으며 그 결과는 다음과 같다. 심정지 환자의 대상은 남성이 162명(73.0%), 여성이 60명(27.0%)으로 주로 남성이 많았다. 연령별로는 50~59세 환자가 54건(24.3%)으로 가장 많았으며, 29세 이하 환자는 4건(1.8%)으로 가장 낮은 빈도를 보였다. 병원 전 자발순환회복에 미치는 영향에는 119구급대의 신고에서부터 출동반응시간, 현장도착시간이 짧을수록 자발순환회복에 영향을 주었으며, 119구급대가 현장에 3분 이내 도착한 경우에 4분 이후 도착한 경우보다 자발순환회복에 유의한 차이를 보였다. 119구급대를 통해 실시된 응급처치 중 전문소생술의 빈도는 낮았으나, 그 중 정맥로 확보가 자발순환회복에 유의한 차이를 보였다. 본 연구를 통하여 119구급대로 이송된 제세동 가능한 심정지 환자의 병원 도착 전 자발순환회복율을 높이기 위해서는 현장에서 목격자의 심폐소생술이 시행되어야 하며 119구급대는 신고에서 출동반응시간, 현장도착시간을 단축시켜 빠른 제세동이 적용되어야한다. This research analyzed the effects on Recovery of Spontaneous Circulation of 222 cardiac arrest patients transported to hospital that can be defibrillated from January 1st 2010 to December 31st 2011. The results are as followed. Males accounted for majority, numbering 162 (73.0%) and females accounted for 60 (27.0%) out of cardiac arrest patients. As for the age, patients of age between 50~59 were the highest with 54 cases (24.3%). Patients below 29 had lowest frequency with 4 cases (1.8%). The effect on spontaneous circulation recovery before hospitalizing showed more significant difference the shorter the response time and site arrival time were from the 119 emergency call, and there also was significant difference on spontaneous circulation recovery when the 119 emergency team arrived the site within 3 minutes than 4 minutes. Among the first-aids performed by the 119 emergency team, frequency of advanced cardiac life support was low and out of this, securing vein showed significant difference in spontaneous circulation recovery. Through this study, in order to raise the spontaneous circulation recovery of cardiac arrest patients before hospitalizing who can be defibrillated, witness' resuscitation should be performed on site and rapid defibrillation should be applied be shortening response time and site arrival time of 119 emergency team.

입체영상의 시각 피로 최소화를 위한 특징기반 시차 보정

정은경(Eun Kyung Jung),김창일(Chang Il Kim),백승해(Seung Hae Baek),박순용(Soon Yong Park) 大韓電子工學會 2011 電子工學會論文誌-SP (Signal processing) Vol.48 No.6

본 논문에서는 입체영상을 시청할 때 흔히 발생할 수 있는 시각 피로를 최소화하기 위한 시차 보정 기술을 제안한다. 시각 피로는 3차원 TV의 상용화에 있어 반드시 풀어야 할 문제이다. 본 논문에서 제안하는 시차 보정 기술은 좌 우 입체카메라의 기하학적 분석을 통하여 영상의 깊이감을 조정하는 수평시차 보정과 특징 정합 기반의 수직시차 보정으로 구성된다. 기존의 시차 보정은 주로 입체영상 카메라의 기하적 관계를 캘리브레이션(calibration) 과정을 거쳐 구하고 그 결과값을 이용하였다. 그러나 캘리브레이션의 오류로 인한 시차의 오차가 여전히 발생하는 문제가 있었다. 본 연구에서는 수평시차는 입체카메라의 캘리브레이션 정보를 사용하는 반면 수직시차는 특징점 정합 기반의 보정 알고리즘을 사용하여 수직시차의 오차를 최소화하였다. 유사한 특징점 정합 기반의 보정 알고리즘과의 비교를 통하여 제안 알고리즘의 성능을 분석하였다. In this paper we propose a disparity correction technique to reduce the inherent visual discomfort while watching stereoscopic videos. The visual discomfort must be solved for commercial 3D display systems to provide natural stereoscopic videos to human eyes. The proposed disparity correction technique consists of horizontal and vertical disparity corrections. The horizontal disparity correction is implemented by controlling the depth budget of stereoscopic video using the geometric relations of a stereoscopic camera system. In addition the vertical disparity correction is implemented by using a feature-based stereo matching algorithm. Conventional vertical disparity corrections have been done by only using camera calibration parameters which still cause systematic errors in vertical disparities. In this paper we minimize the vertical disparity as small as possible by using a feature-based correction algorithm. Through the comparisons of conventional feature-based correction algorithms we analyze the performance of the proposed technique.

M 대학 유아교육과 황 교수의 유아교육과 교수로서의 역할 행위 분석

정은경 ( Eun Kyung Jung ) 미래유아교육학회 2010 미래유아교육학회지 Vol.17 No.4

본 연구는 M 대학(4년제) 유아교육과 황 교수가 유아교육과 교수로서 어떤 역할 행위를 하고 있는가를 알아보기 위해 M 대학 황진주(가명) 교수를 심층 면담하여 유아교육과 교수로서의 역할 행위를 분석해 보았다. 황 교수와 8회에 걸친 심층면담을 통해 총 162쪽의 면담 기록본을 분석한 바 유치원 교사와 닮은꼴의 교수되기, 이론과 실제의 이중주, 연구활동을 통해 강의내용 업그레이드 하기, 유아교육인으로서 자부심 조성하기, 교수의 삶, 학생의 삶 나란히 가기 등의 5개 범주가 출현하였다. 유치원 교사와 닮은꼴의 교수되기는 교수가 학생들을 세심하게 챙기는 분위기를 통해 교수와 학생과의 원활한 의사소통에 긍정적인 영향을 미칠 수 있었고, 이론과 실제의 이중주에서는 이론이 부족하면 현장 적용능력이 저하되고, 이론만 강조하게 되면 실천적 지식이 부족하게 됨음을 의미하였다. 최근의 연구결과를 전달해 주는 교수와 늘 해 왔던 이론을 전달하는 교수와는 그 역할이 다르며, 유아교육과 교수는 학생들에게 전공에 대한 자부심를 갖도록 하며, 교수와 학생은 연구와 강의를 통해 동반자적 삶을 살게 된다. This study was designed to look into role behavior as a professor in the early childhood education department by means of conducting an in-depth interview with Prof. Whang at `M` University. As a result of conducting 8 times of interviews with Prof. Whang at `M` University and analyzing total 162 pages of interview records, five categories of topics emerged: becoming a professor who resembles a kindergarten teacher, the duet between theory and practice, upgrading lecture quality through research activities, instilling pride as a early childhood educator, a partnership with professors with students. The topic of becoming a professor who resembles a kindergarten teacher contributed to bringing about a positive influence on smooth communication between professors and students. The topic of duet between theory and practice illuminated a closely interconnected relationship, where lack of theories damages adaptive capabilities in the field and, on the other hand, too much emphasis on theories leads to lack of practical knowledge. There is a disparity in role between a professor who just conveys traditional theories as usual and a professor who introduces results of recent studies. Early childhood education department professors helped her students to pride themselves on taking up the major and professors and students are destined to have a partnership through research and lecture.
