MIT has been applied for nonfluent aphasic patients on the basis of lateralization of brain hemisphere. However, its applications for different languages have some inquiry for aphasic patients because of prosodic and rhythmic differences. The purpose of this study is to develop the Korean Melodic Intonation Therapy program using personal computer and its clinical effects for nonfluent aphasic patients. The algorithm was composed to voice analog signal, PCM, AMDF, Short-time autocorrelation function and center clipping. The main menu contains pitch, waveform, sound intensity and speech files on window. Aphasic patients' intonation patterns overlay on selected kMIT patterns. Three aphasic patients with or without kMIT training participated in this study. Four affirmative sentences and two interrogative sentences were uttered on CSL by stimulus of ST. VOT, VD, Hold and TD were measured on Spectrogram. In addition, articulation disorders and intonation patterns were evaluated objectively on spectrogram. The results indicated that nonfluent aphasic patients with kMIT training group showed some clinical effects of speech intelligibility based on VOT, TD values, articulation evaluation and prosodic pattern changes.

이 연구는 비유창성 실어증 환자 집단과 정상 성인 집단을 대상으로 단어빈도, 단어길이, 생물성의 세 가지 어휘조건에 따른 이름대기 수행에 차이가 있는지 알아보는 것을 목적으로 하였다. 연구 대상은 비유창성 실어증 환자 15명과 정상 성인 15명이었다. 이름대기 과제의 목표 단어는 그림으로 표현 가능한 구체명사만 사용하였으며, 이름대기 평가는 그림을 이용한 대면이름대기방법을 사용하였다. 목표 단어는 단어빈도(저빈도어/고빈도어), 단어길이(1음절/3음절), 생물성(생물/무생물)의 어휘조건을 적용하여 총 40개의 문항으로 구성하였다. 연구 결과를 살펴보면 다음과 같다. 첫째, 두 집단 모두 고빈도 단어의 이름대기 수행이 저빈도 단어보다 높게 나타났다. 둘째, 두 집단 모두 1음절 단어의 이름대기 수행이 3음절 단어보다 높게 나타났다. 셋째, 두 집단 모두 생물성에 따른 이름대기 수행에는 유의한 차이가 없었다. 넷째, 집단과 어휘조건의 상호작용 효과는 단어빈도에서만 나타났다. 이러한 결과는 비유창성 실어증 환자들의 어휘조건에 따른 이름대기 능력의 저하는 단어길이나 생물성에 비해 단어빈도의 효과가 크다는 것을 시사한다. 이러한 연구결과는 비유창성 실어증 환자의 이름대기 평가와 중재의 기초 자료로 활용될 수 있다.

The present study attempted to determine the effect of olfactory stimulation on word retrieval deficit in Korean aphasics. Eleven nonfluent and 9 fluent aphasic patients served as subjects. The 20 subjects' age ranged from 14 to 65 with the mean of 43.0 (SD: 17.6). A neurologist examined them and diagnosed that they had no visual, auditory, and olfactory impairment. The study consisted of 2 experiments: Experiment I included visual stimulation while experiment II included visual and olfactory stimulation. The subjects were presented with 19 pictures for them to name in the experiment I, whereas they were exposed to the 19 pictures along with the corresponding olfactory stimulus in the experiment II. The 19 items included soy sauce, chilly pepper, Kimchi, chewing gum, cigarette (smoked), soybean paste, lemon, banana, alcohol (wine), apple, fish, vinegar, cuttlefish (dried), milk, rose, sesame oil, melon, coffee, and perfume. The results were as follows: First, olfactory stimulation tended to improve aphasics' word retrieval deficit although the improvement was not statistically significant. Second, the nonfluent aphasics seemed to take more advantage from olfactory stimulation compared to the fluent aphasics. Third, olfactory stimulation (olfactory + visual) did not produce a different naming performance compared to visual stimulation in the pre- and post-test when the pre- and post-test was composed of naming tasks through auditory + visual stimulation. Fourth, the fluent aphasics performed better with unpleasant olfactory stimulus while the nonfluent aphasics performed better with pleasant olfactory stimulus.
