In June of 2016, the Model for End-Stage Liver Disease (MELD)-based allocation system replaced the Child-Turcotte-Pugh (CTP) score-based system for deceased donor liver transplantation (DDLT) in Korea. This study was conducted to reveal the changes before and after the MELD system. Methods: From January 2015 to March 2017, 71 patient datapoints were collected from recipients who underwent DDLT in a single center. Patients were divided into two groups according to the allocation system (41 in the MELD group, 30 in the CTP group). Results: The MELD score of the two groups differed significantly (36.8±4.5 in the MELD group, 26.0±8.1 in the CTP group, P =0.001). There was no difference in etiology for liver transplantation, 6-month survival rate, or in-hospital stay. However, complication rate and re-admission rate within the first 3 months were higher in the MELD group (78%, 56%). No one received a DDLT because of an incentive system for hepatocellular carcinoma. Conclusions: Despite the short-term follow-up period, the new allocation rule reflects the severity of the patients. Almost all patients who underwent DDLT when they had a high MELD score and then suffered from morbidity; however, this problem was associated with organ shortage, not the allocation system.

The purpose of this study was to broaden mutual understandings of mothers and teachers through studying the differences between play beliefs of early childhood teachers and mothers with 3 to 5-year-old children and to propose the need for various educational programs taking into account the characteristics of both mothers and teachers. The subjects of the study were 123 early childhood teachers who are working at daycare centers and kindergartens located in Seoul and Gyeonggi provinces, and 142 mothers with 3 to 5-year-old children. As a result of analyzing the self-reported data of both teachers and mothers, first, according to general characteristics of early childhood teachers, the play beliefs of kindergarten teachers were higher than those of daycare center teachers. Second, as a result of studying the difference in play beliefs according to the general characteristics of mothers with 3 to 5-year-old children, higher levels of play beliefs were found in the group with parental education experiences than in the group without parental education experiences. Third, as a result of examining whether there is a difference in the play beliefs of early childhood teachers and mothers with children aged 3 to 5, it was found that the overall play beliefs of teachers were higher than those of mothers. This study is meaningful in establishing a basic framework for expanding the execution power of play in early childhood by examining play beliefs. 본 연구는 교사와 어머니의 놀이신념을 살펴봄으로써 서로에 대한 이해의 폭을 넓히고, 어머니와 교사 교육 대상자들의 특성을 고려한 다양한 교육의 필요성을 제시해보고자 하였다. 연구 대상은 서울 및 경기 지역에 소재한 어린이집과 유치원에 재직 중인 유아반 교사 123명과 만 3-5세 유아기 자녀를 둔 어머니 142명이다. 교사와 어머니의 자기보고 자료를 분석한 결과, 첫째, 유아반 교사의 배경변인에 따른 놀이신념에서 유치원 교사의 놀이신념이 어린이집 교사보다 높았다. 둘째, 만 3~5세 자녀를 둔 어머니의 일반적 특성에 따른 놀이신념 차이를 살펴본 결과, 부모교육 경험이 있는 집단이 없는 집단보다 높은 수준의 놀이신념을 보였다. 셋째, 유아반 교사와 만 3~5세 자녀를 둔 어머니의 놀이신념에 차이가 있는지 살펴본 결과, 전반적으로 교사의 놀이신념이 어머니보다 높은 것으로 나타났다. 본 연구는 교사와 어머니를 대상으로 유아 놀이에 영향을 미치는 요인 중 하나인 놀이신념을 살펴봄으로써 유아 놀이의 실행력을 확장하기 위한 기초 틀을 제공하는데 의의가 있다.

Purpose: The purposes of this study were to identify the factors influencing service quality in nursing homes, and to develop an evaluation instrument for service quality. Methods: A three-phase process was employed for the study. 1) The important factors to evaluate the service quality in nursing homes were identified through a literature review, panel discussion and focus group interview, 2) the evaluation instrument was developed, and 3) validity and reliability of the study instrument were tested by factor analysis, Pearson correlation coefficient, Cronbach’s α and Cohen’s Kappa. Results: Factor analysis showed that the factors influencing service quality in nursing homes were healthcare, diet/assistance, therapy, environment and staff. To improve objectivity of the instrument, quantitative as well as qualitative evaluation approaches were adopted. The study instrument was developed with 30 items and showed acceptable construct validity. The criterion-related validity was a Pearson correlation coefficient of .85 in 151 care facilities. The internal consistency was Cronbach’s α=.95 . Conclusion: The instrument has acceptable validity and a high degree of reliability. Staff in nursing homes can continuously improve and manage their services using the results of the evaluation instrument.
프랜차이즈 빅데이터를 이용한 사회적 이슈 분석: 감성분석을 통한 감성 사전 구축
이지아,양재장 한국호텔관광학회 2022 호텔관광연구 Vol.24 No.5
본 연구는 감성분석을 통한 프랜차이즈 산업의 사회적 이슈 분석으로 고객의 감정적 인식을 높이기 위한 감정 사전을 구축하여 고객 지향적인 기업 경영전략 및 마케팅 전략을 제시하고자 하였다. 프랜차이즈 기업이 부정적 행위를 하였을 때 오히려 고객들이 옹호하는 상황이 발생한다. 이러한 현상 발생하는 이유는 고객들과 프랜차이즈 기업 사이에 강한 유대감을 형성하고 있으며, 감성이 중요한 역할을 하기 때문이다. 본 연구에서는 강한 유대감을 표현할 수 있는 단어에 주목하여 프랜차이즈에 대한 고객의 감성 사전을 구축하기 위해 프랜차이즈 기업의 뉴스 데이터를 활용하여 감성분석을 실시하였다. 감성분석 결과는 다음과 같다. 첫째, 고객의 반응에 영향을 미치는 긍정, 부정 감성적 요인을 도출하여 프랜차이즈 산업에 적용할 수 있는 감성 사전을 구축하였다. 둘째, 프랜차이즈 산업에서 적용되지 않았던 뉴스 데이터의 감성분석을 통해 연구 범위를 확대하였다. 셋째, 고객이 브랜드에 대해 인지적 요소를 넘어 감정적 인식의 중요성을 확인하였다. 따라서 본 연구는 프랜차이즈 기업은 고객과 지속적인 상호작용을 통해 고객의 감성을 자극할 필요가 있으며, 이에 따른 마케팅 전략을 수립할 필요가 있다. 긍정 감성 사전에서는 ‘성장’, ‘안정적’, ‘최고’, ‘혁신적’이라는 단어에 고객들이 ‘흥미’, ‘호감’, ‘기쁨’이라는 긍정적 감성을 형성함이 나타났다. 또한, 고객들이 프랜차이즈 기업에 거부감을 가지지 않게 마케팅해야 한다. 부정 감성 사전에서 ‘혐오’, ‘공포’, ‘충격’, ‘부담’, ‘불만’은 고객들의 ‘슬픔’, ‘두려움’, ‘놀람’, ‘거부감’을 나타냈다. 이를 참고하여 프랜차이즈 기업의 홍보 언론 기사나 고객이 느끼는 경험에서 부정적인 감성을 줄이는 방안이 필요하다.

Background : Cudrania tricuspidata Bureau belonging to the mulberry family has attracted much attention as a nutrition ingredient many times as many as the mulberry tree. In this study, we examined the inhibitory effect of hot water extract of Cudrania tricuspidata Bureau fruits (CT-F) on inflammation and inflammatory diseases such as diabetes and gastiritis in cell-level experiments and animal models using mice. Methods and Results : The inhibitory effect of CT-F was investigated in LPS_stimulated RAW264.7 macrophages. Treatment with CT-F significantly inhibited the production of inflammatory mediators such as NO, IL-6 and TNF-a. The inhibitory effect of CT-F was shown to be related to inhibition of NF-kB activation in LPS-stimulated macrophages. In in vivo diabetic models using mice, treatment of CT-F lowered the level of blood glucose in alloxan-induce type-1 diabetic model as well as db/db type-2 mice model. CT-F also dramatically inhibited gastiritis induced by EtOH/HCl in mice. Conclusion : Hot water extract of Cudrania tricuspidata Bureau fruits was effective for inhibition of inflammation, diabetes and gastirits. Therefore, CT-F is thought to be a beneficial candidate for development of functional foods to prevent inflammation-associated diseases.
