유정인,이정민,주이진,이동호,윤정희,강효진,안수좌 대한초음파의학회 2020 ULTRASONOGRAPHY Vol.39 No.2

Purpose: The purpose of this study was to evaluate the intra-observer reproducibility of ultrasound attenuation imaging (ATI) for the noninvasive assessment of hepatic steatosis in patients with suspected hepatic steatosis and the inter-observer reproducibility in asymptomatic volunteers. Methods: This prospective study was approved by our institutional review board and informed consent was obtained from all patients. In group 1, composed of patients with suspected hepatic steatosis (n=143), one abdominal radiologist performed gray-scale ultrasonography and two sessions of ATI. In group 2, composed of healthy volunteers (n=18), three independent sessions of ATI were performed by three abdominal radiologists. The visual degree of hepatic steatosis in all study subjects was graded on a 4-point scale by two independent reviewers using gray-scale ultrasonography. Thereafter, the attenuation coefficient (AC) was correlated with the degree of hepatic steatosis using Spearman rank correlation analysis. Intra-class correlation coefficients (ICCs) were used to assess the intra-observer (group 1) and inter-observer reproducibility (group 2) of ATI measurements. Results: For the intra-observer reproducibility of ATI, the ICC was 0.929 (95% confidence interval [CI], 0.901 to 0.949), and the coefficient of variation was 7.1%. Inter-observer reproducibility of ATI measurements showed an ICC of 0.792 (95% CI, 0.549 to 0.916). The AC showed a significant correlation with the visual grade of hepatic steatosis for both reviewers (rho, 0.780 and 0.695; P<0.001, respectively). Conclusion: ATI showed high intra- and inter-observer reproducibility in the assessment of hepatic steatosis.

Assessment of liver fibrosis using 2-dimensional shear wave elastography: a prospective study of intra- and interobserver repeatability and comparison with point shear wave elastography

유정인,이정민,주이진,윤정희 대한초음파의학회 2020 ULTRASONOGRAPHY Vol.39 No.1

Purpose: The purpose of this study was to prospectively investigate the intra- and inter-observer repeatability of a new 2-dimensional (2D) shear wave elastography (SWE) technique (S-Shearwave Imaging) for assessing liver fibrosis in chronic liver disease patients, and to compare liver stiffness measurements (LSMs) made using 2D-SWE with those made using point SWE (pSWE). Methods: This prospective study received institutional review board approval and informed consent was obtained from all patients. Fifty-three chronic liver disease patients were randomly allocated to group 1 (for intra-observer repeatability [n=33]) or group 2 (for inter-observer repeatability [n=20]). In group 1, two 2D-SWE sessions and one pSWE sessions were performed by one radiologist. In group 2, one 2D-SWE session and one pSWE session were performed by the aforementioned radiologist, and a second 2D-SWE session was performed by another radiologist. The intraclass correlation coefficient (ICC) was used to assess intra- and interobserver reliability. LSMs obtained using 2D-SWE and pSWE were compared and correlated using the paired t test and Pearson correlation coefficient, respectively. Results: LSMs made using 2D-SWE demonstrated excellent intra- and inter-observer repeatability (ICC, 0.997 [95% confidence interval, 0.994 to 0.999]) and 0.995 [0.988 to 0.998], respectively). LSMs made using 2D-SWE were significantly different from those made using pSWE (2.1±0.6 m/sec vs. 1.9±0.6 m/sec, P<0.001), although a significant correlation existed between the 2D-SWE and pSWE LSMs (rho=0.836, P<0.001). Conclusion: S-Shearwave Imaging demonstrated excellent intra- and inter-observer repeatability, and a strong correlation with pSWE measurements of liver stiffness. However, because of the significant difference between LSMs obtained using 2D-SWE and pSWE, these methods should not be used interchangeably.

유정인 한국교원대학교 유아교육연구소 2023 한국유아교육연구 Vol.25 No.4

본 연구의 목적은 유아교사의 유아권리존중에 대한 중요도-실행도를 분석하고 향후 개선을 위한시사점을 도출하는 데 있다. 이를 위해 유아교사 176명을 대상으로 유아권리존중에 대한 설문조사를 실시하였다. 수집된 자료는 대응표본 t검증을 통해 중요도와 실행도의 차이를 분석하였으며, IPA 방법을 통해중요도-실행도를 분석하였다. 연구 결과 첫째, 중요도-실행도의 차이는 전체적으로 유의미한 차이가 나타났다. 둘째, IPA 분석 결과 1사분면(유지지속)에는 등원, 정리, 놀이, 의사존중, 정보제공 영역이 위치하였으며, 2사분면에 위치한 영역은 없었다. 3사분면(점진적 개선) 영역에는 소집단, 점심, 특별활동, 자율성 존중 영역이 위치하였으며, 4사분면(과잉투입)에는 기본욕구, 휴식, 개별성 존중 영역이 위치하였다. 본 연구는 유아교육기관에서 이루어지는 교육활동과 일상생활 속에서 유아권리존중을 실천하기 위해 개선해야 하는 내용을제시하였으며, 유아교사가 유아의 권리존중을 실천하기 위해 고민하고 성찰할 수 있는 기회를 제공하였다는데에 의의가 있다. : The purpose of this study is to analyze the importance-execution gap in the respect for children's rights by Early childhood teachers and to derive implications for future improvements. To achieve this, a survey on the respect for children's rights was conducted with 176 Early childhood teachers. The collected data were analyzed for the disparity between importance and execution through paired sample t-tests, and Importance-Performance Analysis (IPA) was employed. The research findings revealed the following: Firstly, there was a significant overall difference in the importance-execution gap. Secondly, the IPA analysis placed the areas of welfare, organization, play, self-esteem, and information provision in the first quadrant (maintain and enhance). There were no areas in the second quadrant. In the third quadrant (gradual improvement), the subgroups of subgrouping, lunch, special activities, and autonomy respect were situated. In the fourth quadrant (over-investment), the domains of basic needs, rest, and individuality respect were identified. This study provides insights into the areas that need improvement for practicing children's rights in educational activities and daily life in early childhood education institutions. It is significant in that it offers Early childhood teachers opportunities to reflect and contemplate on how to actively uphold children's rights.

초고령 노인의 죽음과 함께 살아가는 삶에 대한 내러티브 탐구

유정인,유현실 한국가족학회 2022 가족과 문화 Vol.34 No.3

This study was conducted to explore the experiences and meanings of life living with death in the oldest old. To this end, four oldest old people aged 80 or older were selected who have been bereft of their spouses for less than 5 years or are seriously ill. The in-depth interview data collection was made from December 2020 to March 2021, and 5-8 interview sessions were conducted per participant. According to the narrative inquiry procedure proposed by Clandinin and Connelly(2000), the analysis of the data applied the following five steps: existing in the field, moving to field text, composition of field text, composition of meaning for experience, and composition of research text, and the results are as follow. Three themes were derived in common: a narrative of the death experience of the oldest old; a narrative of life after experiencing death; and a narrative on life preparing for death. In addition, the meaning of life living with death of the participants was derived from four themes: “age that is not strange to die immediately,” “lessons awakened by death in the daily life,” “filling the emptiness of life and moving on to a full life,” and “completing life through the meaning of remaining time.” Based on these findings, the experiences and meanings of life living with death of the oldest old people were discussed in the context of personal, practical, and social justification. The implications of the study results and counseling practice for the elderly were discussed as well as limitations of the study and follow-up research. 본 연구는 초고령 노인의 죽음과 함께 살아가는 삶과 그 의미를 탐구하기 위해 수행되었다. 이를 위하여 배우자와 사별한 지 5년이 안 되었거나 자신이 심각한 질병 중인 80세 이상의 초고령 노인 4명을 선정하였다. 심층면접을 통한 자료수집 기간은 2020년 12월부터 2021 년 3월까지였으며 참여자 1인당 5-8회의 면담을 실시하였다. 자료의 분석은 Clandinin과Connelly(2006)가 제안한 내러티브 탐구 절차에 따라 현장에 존재하기, 현장 텍스트로 이동하기, 현장 텍스트 구성하기, 경험에 대한 의미 구성하기, 연구 텍스트 작성하기 등 다섯 단계를 적용하였으며, 연구 결과는 다음과 같다. 초고령 노인의 일상 속 죽음 경험 이야기, 죽음을경험한 이후의 삶 이야기, 죽음을 준비하는 삶 이야기 등 세 개의 주제가 공통으로 도출되었다. 그리고, 참여자들의 죽음과 함께 살아가는 삶의 의미는 ‘당장 죽어도 이상하지 않은 나이’, ‘삶의 일상에서 죽음이 일깨우는 교훈’, ‘삶의 빈 곳을 채우며 온전한 삶으로 나아가다’, ‘남은 시간의 의미를 통해 삶을 완성하다’ 등 4개의 주제를 발견하였으며, 최종적으로 초고령노인의 죽음과 함께 살아가는 삶의 이야기를 통해 ‘삶의 완성으로서 죽음’이라는 의미를 도출하였다. 이러한 연구 결과를 바탕으로 초고령 노인의 죽음과 함께 살아가는 삶의 이야기와 그것의 의미를 개인적 정당성, 실제적 정당성, 사회적 정당성의 맥락에서 논의하고 연구의 제한점 및 후속 연구에 대한 제언을 제시하였다.

내재(耐齋) 홍태유(洪泰猷) 산문의 주제 의식 연구

유정열(柳正烈) ( Yu Jeong-yeol ) 한국어문교육연구회 2019 어문연구(語文硏究) Vol.47 No.4

본고는 지금까지 본격적으로 조명된 적이 없는 홍태유(洪泰猷)의 산문을 주제 의식을 중심으로 고찰했다. 홍태유는 부친이 당파 갈등의 여파로 인해 죽은 이후 당대 정치 현실과 거리를 둔 채 살아간 인물이었다. 이러한 불우한 상황 속에서도 그는 끊임없이 의미 있는 활동을 하려 노력했으며, 그의 문학 특히, 산문에는 이러한 삶의 지향이 잘 투영되어 있다. 본고는 그 중에서도 ‘外物 애호’와 ‘현실에 대한 관심’을 엿볼 수 있는 산문들의 주제의식을 고찰했다. 먼저 전자와 관련된 산문들을 고찰함으로써 홍태유가 절제된 외물 애호를 추구하고, 나아가 그 애호를 수양의 차원으로 격상시키려 한 사실을 밝힐 수 있었다. 다음으로 후자와 관련된 산문들을 고찰함으로써 그가 科擧 문제와 같은 선비라면 모두 관심을 가질만한 문제는 물론이요, 築城 문제 같은 상당히 특수한 사안에도 관심을 갖고, 그 문제들에 대해 다각도로 고민한 사실을 밝힐 수 있었다. This paper examines the prose of Hong Tae-yu, who has never been fully illuminated, focusing on subject consciousness. Hong Tae-yu lived away from the political reality of his time since his father died in the aftermath of party conflict. Even in this unfavorable situation, he continually tried to do meaningful activities, and his literature, especially in prose, reflects this intention of life. This paper considers, particularly, the subject consciousness of prose that can check the interest in reality and externals. First of all, it was found that Hong, Tae-yu pursued the fond of externals as moderate by examining the prose related to the externals fond, and furthered the external-loving to cultivate level. Next, it was found that he was interested in not only general problems such as state examination; of course, all scholars would be interested, but also very specific issues like building a castle by examining the prose related interested reality and, by extension, he considered the matter from various angles.
