Abstract

The goat of the present research is to improve the quality of life of both the elderly patients with dementia and their caregivers. For this Purpose, we developed a communication aid system that is consisted of three modules such as speech recognition engine, graphical agent. and database classified by a nursing schedule. The system was evaluated in an actual environment of nursing facility by introducing the system to an older mail patient with dementia. The comparison study was then carried out with and without system, respectively. The occupational therapists then evaluated subject"s reaction to the system by photographing his behaviors. The evaluation results revealed that the proposed system was more responsive in catering to needs of subject than professional caregivers. Moreover we could see that the frequency of causing the utterances of subject increased by introducing the system.

본 연구는 치매노인 환자들과 간호사들의 생활의 질의 향상에 목표를 준다. 이를 위해 치매환자를 위한 대화보조 시스템이 제안되었고, 이 시스템은 주로 세가지 모듈, 즉, 음성인식엔진, 화상 에이전트, 간호 시케쥴에 의해 구분된 대화 데이터베이스 등으로 구성되었다. 남성 치매환자에 시스템을 도입함에 의해서 간호시설의 실제적인 환경에서 시스템의 평가가 이루어졌고 시스템이 도입되었을 때와 되지 않았을 때의 비교연구도 실시하였다. 치료 전문가(occupational therapist)들이 비디오 촬영을 통해서 대상자의 반응을 평가한 결과, 치매환자의 요구를 충족시키는데 있어서 대화 시스템이 전문간호사들보다 더 응답적이었다는 것을 보여준다. 게다가, 시스템을 도입함에 의해서 대상자의 발화를 유도하는 빈도가 증가함을 알 수 있었다.
