차유진(Yu-Jin Cha),김세연(Se-Yun Kim) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.3

본 연구는 메타분석을 통해 뇌손상 환자를 대상으로 한 최근 연구들의 지역사회재활의 효과를 ICF 요소별로 알아보고, 최근 지역사회재활 프로그램 적용방법 등을 알아봄으로써 지역사회재활 프로그램의 개발 및 활성화를 위한 기초자료를 제시하고자 하였다. 선정기준에 적합한 논문은 총 15건을 ICF 요소별로 나누어 효과크기 값을 구하였으며 대상 논문들의 동질성 검정과 출판편견 검정을 실시하였다. 그 결과 지역사회재활 프로그램의 전체 효과크기는 0.22였고, ICF 요소별 효과크기는 신체기능과 구조 0.21, 활동과 참여 0.20으로 작은(small) 효과크기를 보였다. 또한 메타분석에 포함된 연구들은 통계적 이질성이나 출판편견이 없는 것으로 간주되어 본 연구 결과는 객관적이고 신뢰할 수 있었다. 이러한 결과는 뇌손상 환자의 지역사회재활 프로그램이 ICF 요소들인 신체기능과 구조, 활동과 참여 요소에 대한 변화 정도 즉 개입 효과를 잘 설명해 주고 있음을 알 수 있었다. In this study, a meta-analysis was conducted to investigate the effect of community-based rehabilitation on patients with brain injury by ICF factor in previous studies and examine the application of recent community-based rehabilitation program. Total 15 articles that satisfied the selection criteria were divided by ICF factors to obtain the effect size. Homogeneity and publication bias were tested for those selected papers. As a result, the overall effect size of community-based rehabilitation was 0.22; the effect size by physical function and structure among the ICF factors came to be 0.21; and the effect size of activity and participation was 0.20, indicating a small effect size. The studies involved in a meta-analysis were considered as the absence of heterogeneity and publication bias, which indicates that the results of this study are subjectively reliable. These results well explained the level of change on ICF factors, specially physical function and structure, activity and participation, in other words, the intervention effect of community-based rehabilitation on patients with brain injury.

지역사회 경도인지장애 노인의 작업회상치료 프로그램의 효과

차유진(Yu-Jin Cha) 한국산학기술학회 2016 한국산학기술학회논문지 Vol.17 No.8

본 연구는 지역사회에 거주하는 경도인지장애로 진단받은 노인들을 대상으로 작업회상치료(ORT)를 적용한 후 인지 기능, 신체적 건강상태, 의사소통과 상호작용 기술 및 우울감에 미치는 효과를 알아보고자 실시하였다. 연구 대상자는 경도인 지장애 진단받은 만 65세 이상의 노인으로 YW 보건소에 등록되어 정기적으로 내원하는 자로 실험군과 대조군으로 임의로 할당하였고 실험군에게 1주일에 1회, 1시간씩 총 8회기 작업회상치료를 실시하였다. 작업회상치료 프로그램은 대상자들의 개별 인터뷰를 통해 공통으로 경험한 사건 및 활동을 확인하고, 선행 연구에서 사용된 프로그램들에 대한 문헌을 고찰하여 종합한 후 내용타당도 검증을 실시하였다. 작업회상치료가 미치는 효과에 대한 전·후간 차이 검증은 paired t-test, 중재 후 실험군과 대조군 간의 변화량 차이 검증은 Mann-Whitney U 검정을 실시하였다. 그 결과 실험군(n=9)이 대조군(n=9)에 비해 인지기능, 신체적 건강상태, 의사소통과 상호작용 기술 및 우울감에서 유의미한 향상을 보였다. 이로써, 작업회상치료(ORT) 는 경도인지장애 노인의 치매를 예방하고 건강 유지 및 증진에 효과적인 비약물적 치료 방법의 하나로 적극 활용될 수 있기 를 기대한다. This study was conducted to apply occupational reminiscence therapy (ORT) to the elderly diagnosed with mild cognitive impairment (MCI) who reside in the local community and determine its effects on cognitive functions, physical health, communication and interaction skills, and depression. The participants were elderly diagnosed with MCI who visited YW community health center on a regular basis and were randomly divided into an experimental group and a control group. The experimental group received eight one hour sessions of ORT once a week. Individual interviews were then conducted with the participants to determine if an event or activity had been commonly experienced, after which the program was modified and supplemented as necessary by referring to previous programs. The Content Validity Index (CVI) was calculated, and differences before and after ORT's were identified by paired t-tests. Moreover, the Mann-Whitney U-test was conducted to identify differences in variances between groups. Only participants in the experimental group (n=9) reported significant improvements in cognitive function, physical health status, communication and interaction skills, and depression when compared to those in the control group (n=9). Therefore, it is expected that ORT will be actively used as a non-pharmacological intervention for preventing dementia and improving the health of elderly persons with MCI.

차유진(Yu-Jin Cha) 한국콘텐츠학회 2016 한국콘텐츠학회논문지 Vol.16 No.6

본 연구의 목적은 우리나라의 65세 이상 노인 집단에 총점으로 사용할 수 있는 단축형 회상기능척도(RFS-S)를 개발하고 정상노인 집단과 경도인지장애 집단에게 RFS-S를 시행하여 RFS-S의 내적신뢰도 및 준거타당도 검증과 인구학적 특성이 회상기능에 영향을 미치는 요인을 알아보고자 하였다. 연구 대상자는 65세 이상 정상대조군 60명, 경도인지자애군 58명으로 두 집단 간 일반적 특성은 유의한 차이가 없었다. 문항 간 내적신뢰도는 0.63이었고, RFS-S와 이야기회상검사, 치매임상평가척도 박스총점과의 수렴타당도는 각 0.20(p<.05), -0.25(p<.001)로 모두 유의한 상관관계를 보였다. ROC 곡선 아래의 면적을 분석한 준거 타당도 결과 0.68(p<.001)로 덜 정확한(less accurate) 검사로 최적 절단점은 17점이었고 이에 따른 민감도는 0.59, 특이도는 0.72였다. 인구학적 변인에 따른 회상기능은 모두 유의한 차이를 보이지 않았다. RFS-S는 정상과 경도인지장애 차이를 판별하는 신뢰도와 타당도가 높은 진단 보조 도구이자 회상치료의 효과를 평가하는 유용한 도구임을 나타낸다. This study aims at developing Reminiscence Function Scale-Short Form(RFS-S) and verifying it as a supplemental diagnosis instrument to judge differences between normal and mild cognitive impairment and useful measure to rate effects of reminiscence therapy in the clinical field through internal consistency reliability and criterion validity. The study also aims at figuring out factors affection reminiscence function by figuring out demographic features of RFS-S. The research subjects were the control group of 60 normal people and experimental group of 58 people with mild cognitive impairment and both groups were over 65 years old. For internal consistency reliability(Cronbach’s alpha) between questions was reliable with 0.63. Convergent validities of RFS-S with SRT and CDR-SB were 0.20(p<.05) and -0.25(p<.001), respectively, as both showed significant correlations. As a result of criterion validity to analyze AUROC, it was 0.68(p<.001) and less accurate. Its optimal cut-off points were 17 and sensitivity according to them was 0.59, and specificity was 0.72, respectively. However, reminiscence function according to demographic variables did not show any significant differences. Therefore, it is expected that RFS-S will be used as a supplemental diagnosis instrument with higher reliability and validity for discerning differences between normal and mild cognitive impairment and as a useful one to verify effects of reminiscence therapy.

유진 ( Jin Yoo ),차은주 ( Eun Joo Cha ) 대한무용학회 2010 대한무용학회논문집 Vol.65 No.-

The purpose of this study is to establish mentoring model in dance and to develop the dance mentoring scale(DMS) by confirming its validity. This study is based on the literatures and theoretical model of our previous studies(Cha & Yoo, 2010). 461 dancers(high-school/college/professional dancers) participated in this study. MANOVAs showed that high-school dancers had significantly higher levels than college and professional dancers, regarding the role model, mental support and the instruction of dance mentoring. The result of SEM showed that dance mentoring and dance motivation model retained a satisfactory fit to the data. Role model and social support had significantly predictors of intrinsic motivation, external regulation and amotivation. These results showed the theoretical application and importance of DMS in dance.

This study systematically attempted to delineate the psychological and organizational mentoring constructs (i.e., functions and contents) affecting dance performance in different developmental phases of the dance career. A Korean dancer who experienced successful relationship with mentors for 29 years was purposefully selected, and an intentive biographical interview was conducted to analyze his mentoring experience. Qualitative research methodology were employed to acquire mentoring experiences of the dancer over four developmental phases. Content analysis organized the quotes into increasingly more higher-order themes and categories representing mentoring functions and constructs. Inductive analyses provided the three major functions of the mentoring relationship. The instructional function consisted of movement instruction and performance instruction. The psychological function was categorized as spiritual supporter (role modeling) and counselling, while the social function included enhancing human network and dance-related public performance. Overall, the dancer perceived spiritual supporter (role modelling) and counselling as being important constructs enhancing the dance performance. These results help to understand successful mentoring relationship in dance.

The objectives of the current study is to understand various aspects of mentoring among dancers(highschool, college, and professional dancers) and their structural relationship with the satisfaction of mentoring. This study collected the data from 324 participants using a questionnaire. The data were analyzed with SPSS 15.0 for WINDOWS. The statistical analyses included frequency analysis, reliability, cross tab, and ANOVA. The results are as below. First, the study indicated that the dancers have maintained a long term relationship with their mentors. The average number of mentors of the dancers was 5.36. For high school dancers, 30.6% had more than 6 mentors. The participants indicated that their mentor was mostly their teacher/coach. They usually have one to two personal contacts with their mentors per week. The age discrepancy between the mentors and mentees was 14 years in average. The average mentoring period was six years and eight months in average. The roles of mentors, in the order of importance, were dancing practice and psychological support. The results also found that the mentors of the participants had significant influence on the performance of the dancers. Second, the dancers indicated that the most important things in the mentoring was (1) mentors` understanding the dancers (mentees), and (2) maintaining a positive relationship. Collegiate dancers perceived mentors` advice and counseling to be the most important. Professional dancers expressed their wish that their mentors had a successful professional career and expressed their gratitude toward their mentors. Highschool dancers wanted to have dance lessons from their mentors. Third, The dancers had more satisfaction as they had more numbers of mentors. The satisfaction level was the highest when the mentors provided mentees with economic supports. The satisfaction level of highschool dancers was statistically higher than that of collegiate and professional dancers. In conclusion, dancers were more satisfied with mentoring when they had more numbers of mentors and when they maintained a longer period of mentoring relationship.
