It is well-known that there are many similarities between Japanese and Korean language. For example, the order of words and the nature of the grammatical conjugation of both languages are almost the same. Another similarity is the frequent omission of the subject from a sentence. Moreover, both languages have honorific expressions and the identical concept for expressing nouns in terms of Chinese characters. Using these similarities, we have developed a word-to-word translation system which does away with any deep level analysis of syntactic and semantic structures of the two languages. If we use these similarities, the direct translation method is superior to the internal language translation method or transfer-based translation method. Although the MT system based on the direct translation method is more easily developed than the ones based on other methods, it may have a lot of difficulties when it tries to select the appropriate target word from ambiguous source verbs. In this paper, we propose a new algorithm to extract the meaning of substantives and to make use of the order of the extracted meaning. We could select $86.5\%$ appropriate verbs in the sample sentences from IPAL-verb-dictionary. $13.5\%$ indicates the cases in which we could not distinguish the meaning of substantives. We are convinced, however, that the succeeding rate can be increased by getting rid of the meaning of verbs thatare not used so often.

This study is a follow-up study of Han and Kang (2013) and Kang and Han (2013) which examined cross-generational changes in the Korean vowels /o/ and /u/ using acoustic analyses of the vowel formants of these two vowels, their Euclidean distances and the overlap fraction values generated in SOAM 2D (Wassink, 2006). Their results showed an on-going approximation of /o/ and /u/, more evident in female speakers and non-initial vowels. However, these studies employed non-words in a frame sentence. To see the extent to which these two vowels are merged in real words in spontaneous speech, we conducted an acoustic analysis of the formants of /o/ and /u/ produced by two age groups of female speakers while reading a letter sample. The results demonstrate that 1) the younger speakers employed mostly F2 but not F1 differences in the production of /o/ and /u/; 2) the Euclidean distance of these two vowels was shorter in non-initial than initial position, but there was no difference in Euclidean distance between the two age groups (20's vs. 40-50's); 3) overall, /o/ and /u/ were more overlapped in non-initial than initial position, but in non-initial position, younger speakers showed more congested distribution of the vowels than in older speakers.

Objective: The current study investigated a non-obtrusive measure for detecting physical fatigue based on the analysis of formant frequencies of human voice. Background: Fatigue has been considered as a main cause in industrial and traffic accidents. Therefore, it is critical to detect worker's fatigue for accident prevention. Method: After running exercises on a treadmill, participants were instructed to read a sentence and their voices were recorded under four different physical fatigue levels. Korean vowels of "아", "어", "오", "우", and "이" from the voice recorded were then used to collect formant 1 frequencies. Results: Results of separate ANOVAs showed a significant main effect of physical fatigue on formant 1 frequency of "아", "어", and "이". Furthermore, post-hoc comparisons revealed that formant 1 frequency of "아" was most sensitive to physical fatigue level employed in this experiment. Conclusion: Formant 1 frequencies of some vowels significantly decrease as the physical fatigue level increases. Application: Potential application of this study includes the development of a measure of physical fatigue state that is free from sensor attachment and requires little preparation.

The purpose of this paper is to provide basic data for development of Korean teaching programs for immigrant women from multicultural families through the acoustic analysis of their speech rate and pauses. They showed slower speech rate, longer pause duration, and higher frequency of pauses compared to a Korean women's group. Philippine women, whose residence duration in Korea is relatively longer than that of Vietnamese women, were more similar to Korean women. The slower speech rate of the immigrant women seems to be due to their slower articulation rate and their reading habit of inserting a pause after almost every word in a sentence.

한국어에서 보조용언은 본용언에 연속적으로 연결되어 나타나서 많은 문법적 기능을 담당하고 화자의 양태 관계를 나타낸다. 그 중에서 사동 보조 용언과 파동 보조 용언이 본용언에 결합되었을 때는 본용언의 하위 범주화 값이 달라지며 문장에서 각 성분들의 의미역할이 바뀌게 된다. 따라서 자연어 이해와 기계번역의 질적 향상을 위해 이들에 대한 정확한 분석이 요청된다. 본 논문에서는 한국어 구문분석에서 보조 용언 처리의 한 부분으로서 사동 보조 용언 '-게 하-'로 실현되는 사동문과 피동보조 용언 '-아/어 지-'로 실현되는 피동문의 구문분석 방법을 제안한다. 사동문에서는 오분석을 막기 위해 사동 보조 용언이 아닌 '-게 하-' 구성을 구별해 내고, 피동문에서는 '-아/어 지-'를 피동보조용언과 기동상으로 분리시킨다. 그리고 이들 보조 용언으로 실현되는 사동/피동문을 격표지 정보와 사동문 분석 규칙, 피동문 분석규칙을 이용하여 사동/피동문이 가지는 의미특성을 나타낸 구문분석 결과를 제시한다.

This study was intended to analyze difference of vocal folds movements between upon wakeup and in several hours later in the morning. The difference of vocal fold movements was compared with fundamental frequency and a range of fundamental frequencies from maximum to minimum. The participants were 30 female adults between 20 and 29 years old. Voice samples were collected from their reading sentence (Jeong, 1993). The first sampling was conducted within 5 minutes after wakeup, while the second on 1 hour after the first sampling. Finally, the third voice sample was collected on 6 hours after the second sampling. The results of this study were as follows: First, fundamental frequency of the participants were by hour significantly time-dependent(F=7.843). Post-hoc multiple comparison (LSD) was conducted to determine when the difference could be observed. The result showed significant differences between upon wakeup and 6 hours later (p< .001) and between 1 hour later and 6 hours later (p< .05). Second, there were a significantly time-dependent ranges of fundamental frequencies of participants by hour (F=3.130). According to the results of the LSD analysis the significant differences in range of fundamental frequencies were found between upon wakeup and 1 hour later and also between wakeup and 6 hours later (p< .05). The results above indicate that vocal fold movements upon wakeup is different from those of several hours later.

In this paper, study on organization factors and algorithm of semiotics in Animation text within Roland Gerard Barthes's Structurism semiotics theory. It is possible through this approach that we can analyse the effective mechanism which delivers messages(or text) of animation, instead of plain analysis of classical semiotics. and then It will be able to keep watch on the blind viewpoint of the pure aesthetics which does not consider a social duty. In the expression of single sentence by the view of Barthes's semiotics theory, the text of animation is 'one sign has duplex role'. when it is explained another, the animation of mass media is special processing that makes conception and significance. in other words, the order of domination likely natural rule assimilate mass people to itself by the animation of mass media

Recent studies on acoustic correlates of stress in English compounds and English phrases have revealed the difference of changes in acoustic manifestation between English compounds and English phrases with different intonation patterns. However, little effort has been made to compare Korean compounds and Korean phrases in different intonational environments. Therefore, this study focuses on the analysis of acoustic characteristics of Korean compounds and Korean phrases produced in different intonational sentence patterns (Subject, Question, Clause-Final, and Statement-Final). Measurements of vowel duration, intensity (dB) and pitch (in semitones) were compared. The results of the experiment in which 30 native speakers of Korean pronounced Korean compounds and Korean phrases (obtained from $8{\times}30$ sentences) in controlled prosodic and intonational environments reveal clear patterns that distinguish Korean compounds from Korean phrases and support the evidence of acoustic salience for phrases. Duration differences turned out to be a significant cue to distinguish Korean compounds and Korean phrases in all but the Clause Final position. According to the size effect, duration ratio is the most reliable cue to distinguish Korean compounds and Korean phrases followed by the pitch differences between the first syllable and the second syllable and the intensity ratio. Implications for Korean and English intonation training were also discussed.

Sasang constitution experts utilize voice characteristics as an auxiliary measure for deciding a person's constitutional group. This study aims at establishing a relationship between speech features and the constitutional groups by subjective listening evaluation of voice characteristics. A speech database of 841 speakers whose constitutional groups have been already diagnosed by Sasang constitution experts was constructed. Speech features related to speech source and vocal tract filter were extracted from five vowels and one sentence. Statistically significant speech features for classifying the groups were analyzed using SPSS. The features contributed to constitution classification were speaking rate, Energy, A1, A2, A3, H1, H2, H4, CPP for males in their 20s, F0_mean, CPP, SPI, HNR, Shimmer, Energy, A1, A2, A3, H1, H2, H4 for females in their 20s, Energy, A1, A2, A3, H1, H2, H4, CPP for male in the 60s, and Jitter, HNR, CPP, SPI for females in their 60s. Experimental results show that speech technology is useful in classifying constitutional groups.
