본 연구는 통합 환경에서 사진교환 의사소통 체계를 이용한 중재가 발달장애유아의 행동요구하기 기능에 미치는 효과를 알아보기 위한 실험연구로서 발달장애유아 3명을 대상으로 주 4회 매회기 45분씩 총 45회기에 걸쳐 실시하였으며 대상자간 중다 기초선실험설계를 하였다. 발달장애유아들의 행동요구하기 기능의 수행율 연구결과는 기초선에서 거의 나타나지 않았던 행동요구하기 기능 수행이 중재 단계에서 대상유아 2를 제외하고는 급속한 상승으로 수행의 증가를 가졌고 일반화 검사와 유지검사에서는 대상유아 모두에서 수행은 중재 단계보다도 더 높은 수치를 보였으며, 또한 기초선 단계에서 거의 나타나지 않았든 행동요구하기 기능 수행의 수단별 사용을 살펴보면 사진교환 의사소통 체계를 이용한 중재를 통하여 사진교환하기와 사진교환하면서 모방발어, 사진교환하면서 자발어 등의 수단 습득에 향상이 있었고, 일반화와 유지 단계에서도 긍정적인 영향을 미쳤다. 그러므로 사진교환 의사소통 체계를 이용한 중재가 발달장애유아들에게 있어서 행동요구하기 기능의 수단별 습득과 수행에 효과적이며 의사소통에 어려움을 가지는 발달장애유아들이 오랜 시간을 지내고 머무르는 어린이집이나 유치원의 통합 환경에서 또래아동들이나 선생님들로부터 손쉽게 접근할 수 있는 중재라 생각된다.

This study was to investigate the effect of the meditation by a communicative system of exchanging pictures on a competition of asking for taking action of the children with developmental disorder in the involved environment. For this purpose, three subjects with developmental disorder participated in the tests which conducted for 45 minutes at a time, 4 times, and a total of 45 times, and the multi-basic lines design was used. The variation in the rate of accomplishment of the competition of asking for taking action of the children with developmental disorder was analyzed to indicate the profile. And the measures for the accomplishment of the competition of asking for taking action were divided into the exchange of pictures, making imitative words while exchanging pictures, voluntaries while exchanging pictures, so forth, and were analyzed the variation in each item in terms of the period of basic line, the period of meditation, the period of generalization, and the period of maintenance. The findings were as follows. Firstly, the meditation by a communicative system of exchanging pictures had an effect on the improvement of three subjects`` competition of asking for taking action in the involved environment. Secondly, the meditation by a communicative system of exchanging pictures had on effect on three subjects`` accomplishment of the measures for the competition such as the exchange of pictures, making imitative words while exchanging pictures, and making voluntaries while exchanging pictures in the involved environment. Thirdly, the meditation by a communicative system of exchanging pictures had an effect on the generalization and the maintenance of three subjects`` accomplishment of asking for taking action and the accomplishment of each measure even after the mediation was finished in the involved environment.
