표기 체계인 한글을 한국어 음가로 변환하는 음운변동 규칙을 역으로 적용하여, 한국어 음가를 한국어를 표기하는 문자 체계인 한글로 전환시키는 규칙을 고안하는 것이 본 연구의 목표이다. 제정된 규칙은 한국어 음성인식에 있어서 매우 귀중한 역할을 담당한다. 일반적인 음성인식 기법은 수회의 학습과정을 통하여 추출된 음성의 표준패턴과 인식 대상으로 입력된 음성을 비교하여 가장 유사한 패턴을 찾는 방법을 사용한다. 이 때 표준 음성패턴이 띄어쓰기 단위의 어절이라면 수백만 개의 표준 패턴이 수록되어야 하므로 표준패턴을 위한 방대한 데이터베이스의 구축은 물론 표준패턴과의 비교 회수도 너무 많아져서 실용화가 불가능하다. 이에 대한 대안인 음절 단위 인식의 경우는 인식된 음가가 실제의 한글 표기와 맞지 않으므로, 인식된 결과를 출력할 때에 실제의 한글표기로 변환해 주어야 하는 과제를 안게 된다. 이 과제를 해결하는 과정, 즉 일련의 한국어 음가들을 일련의 한글 표기 문자로 바꾸어 주는 과정에서는 본 논문에서 제안한 표준 한국어 음가 - 표기 문자 변환 규칙을 적용할 수 있을 것이다. 본 논문에서는 새롭게 제안된 표준 한글 음가-표기 문자 변환 규칙을 사용하여 한국어 음가를 한글 표기로 변환하는 시스템을 구현하였다. 그리고, 고안된 규칙의 무결성을 보이기 위하여 표준 발음규칙 30항을 반영하는 데이터 집합을 이용하여 구현된 시스템을 시험하였으며, 그 실험 결과를 제시한다.

Objective : This study was designed to find the correlation between Sasang Constitution and heart rate variability(HRV). Method : There were 665 subjects (280 men and 385 women), between 39 and 72 years old. in a rural community. Sasang Constitution was diagnosed by a Sasang constitutional specialist using PSSC (Phonetic System for Sasang Constitution), face and tongue photo and checkup-list. A structured-questionnaire was used to assess the general characteristics. HRV was recorded using SA-2000 (medi-core). HRV was assessed by time domain and by frequency domain analysis. Metabolic syndrome was defined on the basis of clustering of risk factors, when three or more of the following cardiovascular risk factors were included : blood pressure, fasting blood sugar, triglyceride HDL-cholesterol, and abdominal obesity (waist). Because of the skewness of the data, logarithmic transformation was performed on the absolute units of the spectral components of HRV, and the resulting logarithmic values and normalized units were compared between the groups by a logistic regression. The 95% confidence interval (CI) of the odds ratio was used and calculated from the data laid out for a cross sectional study. Results : 1. Odds ratios of Taeeumin and Soeumin in female adults below 60 years old were significantly lower than that of Soyangin in LF norm and LF/HF ratio. Odds ratios of Taeeumin and Soeumin in female adults below 60 years old were significantly higher than that of Soyangin in HF norm. 2. There was no significant correlation between HRV and Sasang Constitution in female adults from 60 years old and over. 3. There was no significant correlation between HRV and Sasang Constitution in male adults. Conclusion : There is a statistically significant correlation between the HRV and Sasang Constitution. There is a tendency of increase in the sympathetic activity in Soyangin. There is a tendency of decrease in the parasympathetic activity in Taeeumin and Soeumin.

Processes involving the change of vowel height are natural enough to be found in many languages. It is essential to have a better feature specification for vowel height to grasp these processes properly, Standard Phonology adopts the binary feature system, and vowel height is represented by the two features, i.e., [\pm high] and [\pm low]. This has its own merits. But it is defective because it is misleading when we count the number of features used in a rule to compare the naturalness of rules. This feature system also cannot represent more than three degrees of height, We wi31 discard the binary features for vowel height. We consider to adopt the multivalued feature [n high] for the property of height. However, this feature cannot avoid the arbitrariness resulting from the number values denoting vowel height. It is not easy to expect whether the number in question is the largest or not It also is impossible to decide whether a larger number denotes a higher vowel or a lower vowel. Furthermore this feature specification requires an ad hoc condition such as n > 3 or n \geq 2, whenever we want to refer to a natural class including more than one degree of height The altelnative might be Particle Phonology, or Dependency Phonology. These might be apt for multivalued vowel height systems, as their supporters argue. However, the feature specification of Particle Phonology will be discarded because it does not observe strictly the assumption that the number of the particle a is decisive in representing the height. One a in a representation can denote variant degrees of height such as [e], [I], [a], [a ] and [e ]. This also means that we cannot represent natural classes in terms of the number of the particle a, Dependency Phonology also has problems in specifying a degree of vowel height by the dependency relations between the elements. There is no unique element to represent vowel height since every property has to be defined in terms of the dependency relations between two or more elements, As a result it is difficult to formulate a rule for vowel height change, especially when the phenomenon involves a chain of vowel shifts. Therefore, we suggest a new feature specification for vowel height (see Chapter 3). This specification resorts to a single feature H and a few >'s which refer exclusively to the degree of the tongue height when a vowel is pronounced. It can cope with more than three degrees of height because it is fundamentally a multivalued scalar feature. This feature also obviates the ad hoc condition for a natural class while the [n high] type of multivalued feature suffers from it. Also this feature specification conforms to our expection that the notation should become simpler as the generality of the class increases, in that the fewer angled brackets are used, the more vowels are included, Incidentally, it has also to be noted that, by adopting a single feature for vowel height, it is possible to formulate a simpler version of rules involving the changes of vowel height especially when they involve vowel shifts found in many languages.

영어는 강세 박자 언어로서 강세 변화에 의한 발화의 재구조가 이루어지는 음운체계를 갖는다. 반면 한국어는 각각의 음절을 거의 똑같은 길이와 강도로 발음하는 음절 박자 언어로 일반적 발화 속에서 한국어와 영어는 분명하게 다른 운율체계를 갖는다. 그러나 K-Pop 음악 속에서 노랫말의 언어가 한국어와 영어, 두 가지 언어로 혼용되면서 K-Pop 음악 속에서의 한국어 노랫말은 영어처럼 강세변화에 의한 운율체계를 갖게 되었다. 이러한 한국어 노랫말의 운율구조 변화 현상을 신한류 지속화를 위해 앞으로도 지속될 수밖에 없는 필연적 현상으로 보는 것이 논자의 입장이다. 따라서 본 연구에서는 K-Pop 음악의 주요 장르이자 리듬표현에 중점을 두는 댄스음악을 한류 변화 양상에 따라 1998년, 2003년, 2009년으로 구분하고, 각 시기의 노랫말 운율구조를 비교·분석하였다. 또한 이를 바탕으로 현재의 K-Pop 운율구조 특징을 도출하여 한 음표당 하나의 음절씩 배당하여 작사하던 기존의 제한적 작사법에서 벗어난 K-Pop 한국어 작사법을 제안하였다. 이 연구가 K-Pop에서 한국어 노랫말로 작사할 때의 하나의 방법론으로 활용되기를 바라며, 더불어 한국어 노랫말 사용의 장려 방안이 되기를 기대해 본다.

1 Intonation is important. It cannot be ignored. To convince students of the importance of intonation, we can use sentences with two very different interpretations according to intonation. Example: "I thought it would rain" with a fallon "rain" means it did not rain, but with a fall on "thought" and a rise on "rain" it means that it did rain. 2 Although complex, intonation is structured. For both teacher and student, the big job of tackling intonation is made simpler by remembering that intonation can be analysed into systems and units. There are three main systems in English intonation: Tonality (division into phrases) Tonicity (selection of accented syllables) Tone (the choice of pitch movements) Examples: Tonality: My brother who lives in London is a doctor. Tonicity: Hello. How ARE you. Hello. How are YOU. Tone: Ways to say "Thank you" 3 In deciding what to teach, we must distinguish what is universal from what is specifically English. This is where contrastive studies of intonation are very valuable. Usually, for instance, division into phrases (tonality) works in broadly similar ways across languages. Some uses of pitch are also similar across languages - for example, very high pitch may signal excitement or urgency. 4 Although most people think that intonation is mainly about pitch (the tone system), actually accent placement (tonicity) is probably the single most important aspect of English intonation. This is because it is connected with information focus, and the effects on interpretation are very clear-cut. Example: They asked for coffee, so I made them coffee. (The second occurrence of "coffee" must not be accented). 5 Ear-training is the beginning of intonation training in the VeL approach. First, students learn to identify fall vs rise vs fall-rise. To begin with, single words are used, then phrases and sentences. When learning tones, the fIrst words used should have unstressed syllables after the stressed syllable (Saturday) to make the pitch movement clearer. 6 In production drills, the fIrst thing is to establish simple neutral patterns. There should be no drama or really special meanings. Simple drills can be used to teach important patterns: Example: A: Peter likes football B: Yes JOHN likes football TOO A: Mary rides a bike B: Yes JENny rides a bike TOO 7 The teacher must be systematic and let learners KNOW what they are learning. It is no good using new patterns and hoping that students will "pick them up" without noticing. 8 Visual feedback of fundamental frequency with a computer display can help students learn correct patterns. The teacher can use the display to demonstrate patterns, or students can practise by themselves, imitating recorded models.

1. Objectives and Methods This study was performed to know the relationship between Sasang Constitution and characteristics of ordinary symptoms, inspection diagnosis of face and tongue. There were 666 participants(280 men and 386 women) who answered Sasang Constitutional Checkup list and were taken pictures of faces and tongues. Sasang Constitution was diagnosed by only PSSC(Phonetic System for Sasang Constitution). Distribution of Sasang Constitution and X2 test, kappa value for agreement were calculated using SPSS 10.0. 2. Results From characteristics of ordinary symptoms' point of view, Taeeumin had loud voices, big body shapes and easily sweated themselves. They felt good after sweating and had warm hands and feet. And their upper back, shoulders and chest were, they thought, well developed. They were apt to have meals quickly and overeat themselves. Soyangin and Soeumin had thin body shapes and were difficult to sweat themselves and felt powerless after sweating. They had cold hands and feet. Especially, Soeumin was apt to have meals slowly and a little amounts. They walked so fast. Soyangin was introvert and had developed their abdomen and waist. 'Looking heavy and steady' was higher in Taeeumin, 'delicate and modest' was higher in Soeumin(42.8%) and Soyangin(36.1 %) in first impression. It was thought to be difficult to discriminate Soyangin from Soeumin in first impression and make a notion of right Soyangin's first impression. Soyangin had pinky tongue color and little tongue fur whereas Soeumin had red tongue color and whitish tongue fur. Taeeumin had whitish tongue fur too. 3. Conclusions To diagnose Sasang Constitution much effectively, PSSC results and comprehensive Sasang Constitutional Checkup list extracted from effective Questionnaire items and Face and Tongue Inspection Diagnosis are thought to be needed.

대화체 연속음성은 자연스러운 발화로 낭독체 문장에 비해 잡음, 간투어와 같은 비문법적인 요소가 많고, 발음의 변이가 심하다. 이런 이유로 대화체 연속음성을 인식하기 위해서는 대화 현상을 분석하고 그 특징을 반영하여야 한다. 본 논문에서는 실제 대화음성에 빈번히 나타나는 대화 현상들을 분류하고 각 현상들을 모델링하여 대화체 연속음성 인식을 위한 기본 베이스라인을 구축하였다. 대화 현상을 묵음 구간과 잡음, 간투어, 반복/수정 발화의 디스풀루언시 (disfluencies), 표준전사와 다른 발음을 갖는 발음변이 현상으로 나누었다. 발음변이 현상은 다시 양성음의 음성음화, 음운축약/탈락현상, 패턴화된 발음변이, 발화오류로 세분화하였다. 대화체 음성인식을 위해서 빈번히 나타나는 묵음구간을 고려한 학습과 잡음, 간투어 처리를 위한 음향모델을 각각 추가하였다. 발음변이 현상에 대해서는 출현빈도수가 높은 것들만을 대상으로 발음사전에 다중 발음열을 추가하였다. 대화현상을 고려하지 않고 낭독체 스타일로 음성인식을 수행하였을 때 형태소 에러율 (MER: Morpheme Error Rate)은 31.65%였다. 이에 대한 형태소 에러율의 절대값 감소는 묵음 모델과 잡음 모델을 적용했을 때 2.08%, 간투어 모델을 적용했을 때 0.73%, 발음변이 현상을 반영했을때 0.92%였으며, 최종적으로 27.92%의 형태소 에러율을 얻었다. 본 연구는 대화체 연속음성 인식을 위한 기초 연구로 음향모델과 어휘모델, 언어모델 각각에 대한 베이스라인으로 삼고자 한다.

This study was performed to measure the changes of the mandibular movement and the masticatory muscular activities - anterior temporal and masseter muscle of both side - reflected by intentional increase of anterior guidance angie. For this study, 5 volunteers (3 males and 2 females with average age of 24.0) were selected. Each volunteer had Angle's classification I and did not have any missing tooth except third molar and any extensive restorations. Metallic guide plate was made at volunteer's working model fabricated by improved dental stone and cemented to the palatal surface of maxillary central incisor using resin cement(Panavia $21^{(R)}$) and then adjusted not to give any occlusal interferences at intercuspal position. The activity of masticatory muscles and the changes of mandibular movement were recorded by EMG and Sirognathograph in Biopak analysing system(Bioresearch Inc., Milwaukee, Wisconsin, USA). Measurement was done at before experiment, immediatley after placement, 1 week after placement, immediately after removal, and 1 week after removal. The results were as follows: 1. Moderate phonetic disturbance and mild headache were occured to 3 volunteers for 2 days after setting and 1 volunteer had positive reaction to percussion and slight midline diastema. But all of these clinical signs were diappeared 1 week after removal and the other volunteer did not have any special clinical sign. 2. In the EMG of the mandibular rest position, the mean value of anterior tempotal muscle was increased immediately after placement(p<0.01) and then decreased 1 week after placement(p<0.05) and increased 1 week after removal(p<0.05) but not recovered as before experiment. The mean value of masseter muscle was decreased during the experiment period. 3. In the EMG during mandibular protrusive movement, all muscular activity was decreased during the experiment period. Reduced activity was not recovered 1 week after removal(p<0.03). 4. During the habitual opening, anteroposterior movement of mandible was decreased immediately after placement(p<0.05) and then increased 1 week after placement but not statistically significant(p>0.1). Vertical movement was not shown significant difference during the experiment period(p>0.1). Lateral movement was decreased immediately after placement(p<0.05) and then increased 1 week after placement but not recovered as before experiment. The opening and closing velocity of mandible was shown minor changes but not statistically significant. 5. During the habitual opening, anteroposterior movement of mandible was decreased 1 week after placement(p<0.05) and then increased immediately after removal and recovered 1 week after removal as before experiment. Vertical movement was not shown significant changes. Lateral displacement of mandible was increased continuously and recovered 1 week after removal. Opening velocity was temporarily increased immediately after removal but recovered and closing velocity was not shown significant changes. 6. During the right side chewing, anteroposterior movement of mandible was increased immediately after removal but recovered and vertical movement was not shown statistically significant results. Lateral displacement and velocity of mandible were not shown significant results. 7. During the left side chewing, the changes of mandibular movement pattern were not shown statistically significant results.
