본 논문은 초등학교 예비교사 100명을 대상으로 수학적 '문제 만들기'의 문장에 나타나는 오류를 분석하고 그에 대한 간단한 예방책을 기술한 논의이다. '문제 만들기' 문장에는 '음운 오류, 단어 오류, 문장 오류, 의미 오류, 표기 오류' 등 5가지 오류 유형이 나타났다. 이를 다시 14개의 세부 유형으로 구분하여 세부적으로 논의하였다. 곧 음운 오류의 유형은 'ㄹ'첨가 오류와 조사끼리의 준말 사용 오류가 있다. 단어 오류는 크게 '부적절한 사용 오류'와 '부당한 생략 오류'로 구분하고 이를 다시 조사, 어미, 어휘의 사용 오류와 조사와 어휘의 부당한 생략 오류로 유형화하였다. 문장 오류는 '지시 대상의 오류, 문장 성분의 생략 오류, 어순 오류, 자체 비문'의 네 가지로 유형화하였다. 의미 오류는 논리적 모순 관계 오류와 중의성을 띄는 의미 오류에 대해서만 논의하였고, 표기 오류는 띄어쓰기와 문장 부호, 철자에 관한 한글 맞춤법 오류와 외래어 표기법 오류 등에 대하여 논의하였다. 또한 14개의 문법적 세부 오류 유형을 방지하기 위한 예방책을 제시하였다. 먼저 구어와 문어의 차이를 인식하고, 둘째 글을 쓰는 문어 상황에 맞도록 구어적 표현을 지양하도록 하는 것, 셋째 국어 기본 문형 학습에 대한 강조, 넷째 단어 의미의 명확한 이해를 바탕으로 한 의미의 논리적 전개 인식을 제안하였으며, 끝으로 국어 어문 규정에 대한 학습을 제안하였다. 그리고 대학생 글쓰기 교육에 대한 필요성에 대한 재인식을 결론으로 갈음하였다.

The purpose of this study is to find the influence of Chinese falling-rising tone on the pitch pattern of corresponding Sino-Korean words delivered by Chinese learners of Korean and to examine how the falling-rising tone of corresponding Chinese words affect the pitch patterns of Sino-Korean words. The scope of this research is limited to Chinese learners of Korean, especially when they pronounce same-form-same-meaning Sino-Korean words. In this study, Chinese learners pronounced both Chinese words and corresponding Sino-Korean words. Learners' pitch patterns were recorded and analyzed using software and compared with the tone of corresponding Chinese words. Experimental results showed that Sino-Korean words were affected by Chinese 'falling-rising tone - high and level tone' when they started with lenis sounds. On the other hand, when Sino-Korean words started with aspirated sounds they were affected by Chinese 'falling-rising tone - high and level tone', 'falling-rising tone - falling-rising tone', and 'falling-rising tone - falling tone'. In conclusion, the Chinese learners' pitch patterns of Sino-Korean words are affected by Chinese falling-rising tone, especially when Sino-Korean words start with aspirated sounds.

This study examined the speech intelligibility of one-syllable words with phonetic contrasts and analyzed segmental factors that can predict the overall speech intelligibility in hearing-impaired adults. To identify the speech error characteristics, a Korean word list was audio-recorded by 7 hearing-impaired adults, and 35 listeners selected the heard word out of 5 choices. Based in part on previous studies of speech of the hearing impaired, the word list consisted of monosyllabic consonant-vowel-consonant (CVC) real word pairs. Stimulus words included 77 phonetic contrast pairs. The results showed that the percentage of errors in final position (coda) contrast was higher than in any other position in syllable. And the intelligibility deficit factors of phonetic contrast in the hearing-impaired were analyzed through stepwise regression analysis. The overall intelligibility was predicted by the error rate of manner contrast at coda, voicing contrast (homorganic triplets) at onset and high-low contrast at nucleus.

This paper is about an experiment of speaker-independent automation Korean spoken words recognition using Multi-Layered Perceptron and Error Back-propagation algorithm. The words were not segmented into syllables or phonemes, and some feature components extracted from the words in equal gap were applied to the neural network. This paper tried to find out the optimum conditions through various experiment which are comparison between total and pre-classified training.

The current study examines the role of post-lexical tonal patterns of a prosodic phrase in word segmentation. In a word spotting experiment, native Korean listeners were asked to spot a disyllabic or trisyllabic word from twelve syllable speech stream that was composed of three Accentual Phrases (AP). Words occurred with various post-lexical intonation patterns. The results showed that listeners spotted more words in phrase-initial than in phrase-medial position, suggesting that the AP-final H tone from the preceding AP helped listeners to segment the phrase-initial word in the target AP. Results also showed that listeners' error rates were significantly lower when words occurred with initial rising tonal pattern, which is the most frequent intonational pattern imposed upon multisyllabic words in Korean, than with non-rising patterns. This result was observed both in AP-initial and in AP-medial positions, regardless of the frequency and legality of overall AP tonal patterns. Tonal cues other than initial rising tone did not positively influence the error rate. These results not only indicate that rising tone in AP-initial and AP_final position is a reliable cue for word boundary detection for Korean listeners, but further suggest that phrasal intonation contours serve as a possible word boundary cue in languages without lexical prominence.

컴퓨터가 상용화되면서 일반인들은 문서를 작성하기 위해 컴퓨터를 이용하는 방법을 자주 사용하게 되었다. 컴퓨터를 이용하여 문서를 작성하는 방법은 작성 속도가 빠르고 손의 피로가 적지만 철자오류가 발생할 확률이 매우 높다. 보통 철자오류는 발견하기 쉽기 때문에 곧바로 수정이 가능하지만, 사용자의 지식 부족 혹은 눈에 잘 띄지 않는 철자오류도 존재하기 때문에 철자오류가 존재하지 않는 문서를 작성하기 어렵다. 온라인상에서는 문서 작성에 대한 규칙 및 예절이 미비하기 때문에 철자오류에 의한 문제가 적지만 중요문서에서 발생하는 철자오류는 신뢰도 하락과 같은 큰 문제를 일으킨다. 철자오류 교정은 전문가 또한 완벽하게 수행하기 힘들기 때문에 비전문가인 일반인들을 위한 교정방법연구가 필요하다. 본 논문에서는 한글 편집거리 알고리즘을 이용해 철자오류를 교정하는 연구를 진행한다. 이전 연구를 통해 검출한 철자오류를 수집한 말뭉치 사전에서 등장하는 단어 중 철자오류 단어와 가장 유사한 단어를 발견하여 주위 단어와의 동시등장빈도를 계산하는 것으로 철자오류 교정을 수행하게 된다.

Many studies have reported an age-related decline in the ability to spell words correctly. The aim of this study was to investigate the deterioration on retrieving orthographic knowledge in 64 normal elderly Korean persons. The subjects were 64 in total: they were composed of 22 persons in their 50s, 20 persons in their 60s, and 22 persons in their 70s or older. We instructed them to write from a dictation of 60 words stimuli (20 regular words, 20 irregular words, 20 nonwords). Older adults made more errors than younger adults, and the age-related decline in performance was greater for irregular than regular and nonwords. With respect to the error pattern in the irregular words, the subjects showed more phonological plausible errors than phonological implausible errors. The number of self-correction was high in nonwords. Based on the results, we found that aging differentially affects the retrieval of orthographic knowledge on regular, irregular and nonwords.

The purpose of this study is to find the influence of Chinese falling-rising tone on the pitch pattern of corresponding partly-different-form-same-meaning Sino-Korean words delivered by Chinese learners of Korean and to examine how the falling-rising tone of corresponding Chinese words affects the pitch patterns of Sino-Korean words. The scope of this research is limited to Chinese learners of Korean, especially on two groups of Sino-Korean words - AB:CB type and AB:AC type that the are second-most frequently occuring different-form-same-meaning Sino-Korean words. In this study, Chinese learners pronounced both Chinese words and corresponding Sino-Korean words. Learners' pitch patterns were recorded and analyzed using software and compared with the tone of corresponding Chinese words. Experimental results showed that AB:CB type Sino-Korean words were not affected by Chinese 'falling-rising tone - high and level tone'. As well as AB:CB type, experimental results showed there were no significant influence on the pitch pattern of AB:AC type Sino-Korean words by Chinese falling-rising tone. But it was clear that Chinese learners' made pitch errors on both AB:CB type and AB:AC type Sino-Korean words. In conclusion, the Chinese learners' pitch patterns of partly-different-form-same-meaning Sino-Korean words are different from Korean native speakers', but their pitch errors cannot be attributed to Chinese falling-rising tone.

The purpose of this study was to investigate the acquisition of number-word systems of young children. Specifically, the acquisition of Korean Number-Words(KNW) was compared with the acquisition of Chinese-derived Number-Words(CNW). The subjects included 120 children aged 2:5 to 5:11. The subjects oral counting using the two number word systems were audiotaped. Two coders transcribed the tapes. The data were analyzed by content analysis with descriptive statistics. The findings of this study showed that the acquisition of KNW began from around age two and the acquisition of CNW from around age three. From then, the acquisition of the two number-word systems was parallel. The acquisition of number-words began from the age of 2 years, increased slowly to the age of 4. and then increased rapidly after the age of 5. Although KNW were acquired earlier than CNW, at around the age of 5 years the acquisition of CNW surpassed the acquisition of KNW. The acquisition of number words consists of four developmental levels: Level I: beginning of acquisition of traditional KNW only Level II: beginning of acquisition of CNW with extension of KNW Level III: parallel extension of the two number-word systems Level IV: superior acquisition of CNW. The major error through all stages in the sequence of number words was the omission of one number-word. Younger children produced errors of omission of one, two or three number-words, whereas older children produced errors of nonstandard number-words and repetition.

The purpose of this study is to examine the influence of Chinese high and level vs. rising tone on the pitch pattern of corresponding Sino-Korean words delivered by Chinese learners of Korean and to examine the aspects how these two tones of corresponding Chinese words affect the pitch patterns of Sino-Korean words. Scope of this research is limited to the Chinese learners of Korean, especially when they pronounce same-form-same-meaning Sino-Korean words. In this study, Chinese learners pronounced both Chinese words and corresponding Sino-Korean words. By using the software learners' pitch pattern were recorded, analyzed, and compared with the tone of corresponding Chinese words. Experimental results showed that Sino-Korean words were affected by Chinese 'high and level tone - high and level tone', 'high and level tone - rising tone', 'high and level tone - falling-rising tone', 'high and level tone - falling tone' and 'rising tone - falling tone' when they started with lenis sounds. On the other hand when Sino-Korean words started with aspirated sounds they were affected by Chinese 'rising tone - high and level tone', 'rising tone - rising tone', 'rising tone - falling-rising tone', 'rising tone - falling tone'. In conclusion, the Chinese learners' pitch patterns of Sino-Korean words are affected by both Chinese high and level & rising tone, especially when Sino-Korean words started with lenis sounds they were more affected by Chinese high and level tone, on the other hand Chinese rising tone influence Sino-Korean words more when they were started with aspirated sounds.
