An Electropalatographic (EPG) study was made to investigate the articulatory distinction of three series of Korean stops according to tensity and the articulatory mechanism associated between tensity and coarticulatory effects. The results indicated that tensity of Korean stops is closely related to contact width and duration of complete closure, and that coarticulatory vocalic effects vary inversely with the degree of contact width and duration of complete closure.

In modem days when architectural materials have grave impacts on overall design expression, materials for architecture, especially finishing materials have become the most essential elements for the design expression, as architectural space and form have been. This study closely verifies the concept of tensity analyzed in preceding studies by quantifying it through experimentation and questionnaire, and suggests possible alternatives which verified concept of tensity applies into the architectural design. It was examined how architects consider the finishing materials through a questionnaire. With a questionnaire, the possibility of quantificative analysis for tensity is evaluated by SPSS program. Moreover, a questionnaire about the social image that the architectural finishing materials have was also conducted. This questionnaire results In the actual methods to apply quantificated psychological tensity and social images into the architectural design and recommends better plan to select finishing materials for each spacial function and usage, Due to the great influence of social images in design expression, the application mechanism of the tensity should follow the general and individual principles together. With the tensity figure and application of social images we can find more resonable method for material selection.

This study aims to show why and how the shift in the point of articulation for Korean consonants occurs with an increase of their tensity. From an EPG study on the point of articulation for Korean alveolar stops, fricatives and velar stops, it was concluded that the shift in the point of articulation occurs because the increase in the tensity of Korean consonants requires more contact area with the roof of mouth by the tongue, and that the direction of the shift depends on the surface shape of tongue for the plain consonant.

An Electropalatographic (EPG) study was conducted to investigate the articulatory characteristics which determine the, distinction between the Korean lax fricative [s] and tense fricative [s']. This study also intended to test if an increase in the degree of tensity (lax fricative [s] < tense fricative [s']) induces a decrease in coarticulatory vocalic effects. The results indicated that the increase in the tensity of Korean fricatives is closely related to the increase in the narrowness of the groove width (wider contact at the place of articulation), the forward shifting in the place of articulation, and the longer duration of the constriction (longer maintenance in the manner of articulation). It was also found that coarticulatory vocalic effects on Korean fricatives are affected by Recasens' two rules of constraint (1983) : spatial and temporal constraints.

In modern days when architectural materials have grave impacts on overall design expression, materials for architecture, modern architecture into the service facility for business, education, religion, cultural assembly and residence, and evaluates each finishing material mainly used in exterior, lobbies and entrances of the building since the 1970's. When being applied social images into firstly selected materials, the scopes for material selection will be more narrowed down in more practical way. High tensity materials are suitable for public and active space and low tensity are for private and static area. This principle enables us to use architectural materials as one of the important elements which express the whole characteristics of the area.

There are four types of color model to repesent color, which are RGB, IHS, CMY, and YIQ color model. RGB color model is the designation of the digital numbers(DNs) of the three primary colors(red, green, and blue), which are used to produce color images on color monitors. IHS color model is the designation of in-tensity, hue, and saturation(IHS). An advantage of considering color in terms of IHS over that of RGB is arrives more easily at a desired color product mathematically. In this study, authors use the IHS transformation and in-tensity-adjustment method to produce the color map images with Landsat TM and scanned map image. And, authors suggest the problems and their solutions when users produce the desired new images with satellite images and map images.

The characteristic of rainfall intensity in short duration is very important to calculate short-term runoff in small watershed by Rational method. Therefore, the purpose of this study is to derive the most proper formula on the probable rainfall intensity in each return period in Daejeon area. And the results of this study could be utilized for the design of drainage-structures in small watershed, drainage system in urban area and flood control in small river basin. The result s of this study are summerized as follows. 1. Gumbel-Chow method which shows the mean value was chosen to calculate the probable rainfall in tensity in each return periods. 2. According to statistical judgement, probable rainfall intensity formula of Japanese type($I={\frac{a}{t+b}}$, see Table-6) shows the most proper one among other types of formula like Talbot type, Sherman type and Characteristic coefficient method. Probable rainfall in tensity value of Japanese type in Daejeon area shows well coincidence with the one obtained by applying prof. Park's n-coefficient to Monobe formula $I=({\frac{R_{24}}{24}})({\frac{T}{t}})^{0.5486}$. On the other hand, the value by Monobe formula with n-coefficient of 2/3 which is being used as a disign criterison by M. O. C. shows large difference from the fore-mentioned results (see Table-7). Consequently the value by Monobe formula might be judged that it is too much overestimated one as a design criterion. 3. Short-term runoff in small water shed could be calculated more reasonably in Daejeon area through this probable rainfall in tensity formula.

현존하는 문헌에 의하면, 입술근육의 수축과 운동시간의 측면에서 영어의 자음을 경음-연음분류를 할 수 있는 음성학적 실증이 없는 것으로 나타나고 있다. 본 연구는 근육운동 측정기를 사용하여 영어와 한국어의 양순 정지음의 발화시 근육(orbicularis oris superior muscle)운동을 측정하였다. 영어의 강세음절에서는 기존의 주장과 같이 /p/와 /b/의 발화시 근육운동에 차이가 없거나 일관성이 없는 것으로 나타났으나, 무강세음절에는 기존 이론과 달리 근육운동수축에 있어서 /p/가 /b/에 비하여 통계학적으로 훨씬 큰 것으로 나타났다.(중략)

The metrical structures in orally produced the poetry were generally analyzed by accent, metre and syllable. The purpose of this study is to investigate of metrical structures of Korean modem poetry using computer implemented speech analysis system. Two famous poet's poems confidential talk, Miloe and 'A buddhist dance, Sungmu' were selected for prosodic analysis. The informant is 60 years old professor in major of Korean and French poetry. The syllable structures of poems were analyzed primarily by vowel timbers, which can classified compact and diffuse vowels according to the distance of F2-F1. The perception cues of consonants were analyzed by VOT and tensity features of articulation. Rhythm is classified by dactyl, anapest, trochee, spondee and iambic. As a result, syllable structures of Korean modem poetry were mainly CV and CVC and the reading times of each lines were 3-4sec for 12 and 15 syllables. Main metre of Korean modem poems constructed the Imbic and Anapest. The break of each lines were demarcated by grammatical structure or meaning rather than phonetic structures.

Previous studies reveal that in English there is no EMG evidence fur the feature tense-lax distinction. The technique of electro-myography(EMG) was used to see if the existing claim holds true, particularly in unstressed syllable. It was found that in unstressed syllable, the peak EMG amplitude from the orbicularis oris superior muscle was significantly greater in /p/ than in /b/, while in stressed syllable this difference was negligible. It was hypothesized that in stressed syllable, /p/ and /b/ may be differentiated by the EMG activities from a muscle other than the orbicularis oris superior muscle, e.g. the respiratory muscles relating to 'aspiration' or depressor anguli oris muscle. In Korean, there was a clear labial gestures for the feature tense-lax distinction. The phoneme-sensitive manifestation of stress and some possible reasons for the inter-speaker variability in the data and the variability within a given speaker were discussed.
