This paper proposes an algorithm for machine recognition of phonemes in continuously spoken Korean. The proposed algorithm is a static strategy neural network. The algorithm uses, at the stage of training neurons, features such as the rate of zero crossing, short-term energy, and either PARCOR or auditory-like perceptual linear prediction(PLP) but not both, covering a time of 171ms long. Numerical results show that the algorithm with PLP achieves approximately the frame-based phoneme recognition rate of 99% for small vocabulary recognition experiments. Based on this it is concluded that the proposed algorithm with PLP analysis is effective in phoneme recognition.

A series of preliminary experiments were carried out to quantify the annoyance are noisiness caused by floor impact noise. From the results of the experiments. the heavy impact source was found to be felt louder and noisier than the light impact source. Measurements of noise were also conducted by a diagnostic system based on the model(the model consists of the autocorrelators and the cross-correlation for signals arriving at two ear entrants) of the human auditory-brain system. Physical factors in the model were calculated by use of the ACF(autocorrelation function) and IACF(interaural cross correlation function) of binaural signals. From the ACF/IACF analysis, it was found that perceived loudness of floor impact noise could be represented by the factors of the ACF/IACF model.

14 patients, whose were attacked pain dysfunction syndrome of temporomandibular joint in Dental College Infirmary, Seoul National University from June 1970 to Dec. 1971, were examined regarding to clinical observation and electromyographical analysis. This paper established the followings: 1. Especially young female was more frequently attacked by pain dysfunction syndrome of Temporomandibular joint. 2. It is suggested that most of joint pain was occurred initially in opening mouth and forcible bite, and left side is more attacked than right side. 3. It was possible that this dysfunction can be occurred by open-bite, premature contact and ill-fitting prosthetic restoration. 4. Hoby, habit and bruxism as causal factors are not markedly related with this dysfunction. 5. Pain attacked regions, in most patients, are preauricular, joint itself, infra-auricular, cervical and external auditory meatus region. 6. In electromyographical studis, the musle activities of affected side of pain dysfunction syndrome are more strong than that of opposite side.

To realize a traditional music recognition system, some characteristics pertinent to Far East Asian music should be found. Using Spectrogram, some distinct attributes of Korean traditional music are surveyed. Frequency distribution, beat cycle and frequency energy intensity within samples have distinct characteristics of their own. Experiment is done for pre-experimentation to realize Korean traditional music recognition system. Using characteristics of Korean traditional music, $94.5\%$ of classification accuracy is acquired. As Korea, Japan and China have the same musical roots, both in instruments and playing style, analyzing Korean traditional music can be helpful in the understanding of Far East Asian traditional music.

After reading a document, people construct a concept about the information they consumed and merge multiple words to set up keywords that represent the material. With that in mind, this study suggests a smarter and more efficient keyword extraction method wherein scholarly journals are used as the basis for the establishment of production rules based on a concept information of words appearing in a document in a way in which author-provided keywords are functional although they do not appear in the body of the document. This study presents a new way to determine the importance of each keyword, excluding non-relevant keywords. To identify the validity of extracted keywords, titles and abstracts of journals about natural language and auditory language were collected for analysis. The comparison of author-provided keywords with the keyword results of the developed system showed that the developed system was highly useful, with an accuracy rate as good as up to 96%.

This presentation aims to explore some possibility of non-segmental phonetics usually ignored in phonetics education. In pedagogical phonetics, especially ESL/EFL oriented phonetics speech sounds tend to be classified in two criteria 1) 'pronunciation' which deals with segments and 2) 'prosody' or 'suprasegmentals', a criterion that deals with non-segmental elements such as stress and intonation. However, speech involves more dynamic processing. It is non-linear and multi-dimensional in spite of the linear sequence of symbols in phonetic/phonological transcriptions. No word is without pitch or voice quality apart from segmental characteristics whether it is spoken in isolation or cut out from continuous speech. This simply tells the dichotomy of pronunciation and prosody is merely a useful convention. There exists some room to consider dynamic non-segmental phonetics. Examples of non-segmental phonetic investigation, some of the analyses conducted within the frame of Firthian Prosodic Analysis, especially of the relation between vowel variants and foot types, are examined and we see what kind of auditory phonetic training is required to understand impressionistic transcriptions which lie behind the non-segmental phonetics.

인간은 음에서도 색을 느낄 수 있다. 그리고 청각을 통하여 음의 높고(고음), 낮음(저음), 장(길고), 단(짧음), 맑고, 탁함에 따라 색을 다르게 느낄 수 있다. 이러한 현상을 색청(色聽)이라고 한다. 소리와 색의 연관성에 대하여 선행 연구를 고찰한 결과 색의 3속성 색상, 채도, 명도는 음악의 음계, 옥타브, 음색과 연관성이 있었다. 그리고 음악의 리듬은 조형의 공간, 형태의 조화와 반복이 유사하다는 것을 알 수 있었다. 본 연구는 에드워드 마이언(Edward D. Maryon)의 마르코톤의 음과 색의 이론을 바탕으로 뉴턴의 색채와 음계로 경상도 민요 밀양아리랑의 색채를 분석하였다. 분석 결과 밀양아리랑 음의 빈도에 의한 색채는 Blue Violet, Green Blue, Red, Yellow, Orange의 순으로 색채를 추출할 수 있었다. 추출된 색에서 연상되는 형용사 이미지는 힘, 정열, 인내, 열정, 진취적인, 우호적, 야망, 불꽃 등으로 경상도 지역 이미지로 연관 시킬 수 있다. 본 연구는 경상도민요 밀양아리랑의 음을 분석하여 색의 연상이미지와 지역 색을 찾는데 그 의의를 두었다.

The perception of landscape structure can he formed mode clearly, with including an auditory stimulus to a visual aspect. The waterfall, as an landscape element, will be considered of not only it's function and structure in landscape architecture designing but also harmony with environment which it has been situated, and contribution to the public goad. The purpose of this study was to establish more 7rational and practical design theory for the construction of waterfall. The number of subjects investigated were 47 of waterfall located in Mt. Palgong. In this study, the acoustic character of the waterfalls were investigated as an excellent effect to mask easily sensible noises. The correlations between the structure of waterfalls and water 1a17ing sound, which were useful for waterfall design and construction, were examined. It was discovered that the position of double distance of waterfall height From the waterfall is significant in the visual and acoustic perception of waterfall.

본 논문은 청각 자극이 제시되었을 때 변화되는 뇌파로부터 의미 있는 특징을 찾아내서 정량화 할 수 있는 변수 추출 및 분류 기법을 제시한다. 건강한 피실험자로부터 방향성 있는 청각 자극을 인가했을 때의 뇌파를 검출, 분류하였다. 뇌파의 변수 추출 방법으로는 짧은 시간영역에서의 신호의 갑작스런 변화량도 정량적으로 분석할 수 있는 Mallat's A1gorithm을 이용한 웨이블릿 변환(wavelet transform)을 적용하였고, 분류 방법으로는 그 결과로 나온 웨이블릿 계수를 변수로 하여 Neural Network을 학습하여 사용하였다. 향후 피실험자의 훈련을 통해서 청각 자극이 없이 순수한 생각만으로 방향을 검출할 수 있는 뇌파분석기를 만든다면 생각만으로도 물체의 방향을 제어할 수 있을 것이다.

The purpose of this study is to identify relationships between safety and health indices in a shipbuilding industry. From the results of periodical health examination, job stress test, and health questionnaire for musculoskeletal disorders, the author stratified the 704 shipbuilding workers into categories of smoking, drinking frequency, the amount of exercise per week, obesity, blood pressure, diabetic symptoms, liver function, audibility, job stress, fatigued condition, musculoskeletal symptom, and accident. The results show that occupational injuries are highly related to smoking, drinking frequency, auditory capacity, fatigued condition, and musculoskeletal symptoms. These results can be used to develop more effective accidental occupational injury prevention programs for shipbuilding industries.
