佛語 母音體系의 변화 : 强勢位置의 경우 Dans la position tonique

李輝子 亞洲大學校 1985 論文集 Vol.8 No.-

Le but de cette etude est de faire la synthese des voyelles contemporaines de francais pour la comparaison avec celle de coreen. L'etude de la comparaison des deux voyelles sera le sujet de notre etude qui va etre continue. Nous avons commence par le systeme traditionnel des voyelles francaises en etudiant le processus de l'evolution dy systeme vocalique de francais, nous avons abouti au systeme que voici: voyelles orales voyelles nasales non-lab. labiales i y u e ø o ε æ ?? ?? ?? a ?? Le caracteristique de ce systeme est - l'opposition entre /ε-ε:/, /a-??/ n'existe plus. - l'opposition /??/ est en voie de disparition, ce qui n'est pas du a la difficulte articulatoire mais au peu de rentabilite fonctionnelle. - l'opposition entre les voyelles mi-fermees et mi-ouvertes n'est pas tres claire mais existe encore. Parmi les voyelles de cette serie, l'opposition /o-??/ est la plus nette. - (??) muet se prononce comme(ø) en position tonique, par consequent l'opposition /ø-æ/ se remplace l'opposition entre /??-ø/, /??-æ/ en position tonique.

Children's drawings are the result of the self-expression of their living existance, and a reflection of their growth and development. The object of tis study is to try to clarify the meaning of the form symbols and the process of occurrence of Kopffusseler, a form of expression used to understand the character of this kind of very young children's drawings. And so, the researcher considered Kopffusseler's process of occurrance and process of development, also the composition factor of the Kopffusseler form, taking symbolism as his central point. First, the results of considering Kopffusseler's process of occurrance are as follows: 1. Kopffusseler occurrence period is from about age 3 to 4 of the early chilhood stage, and generally this applies to the pre-shematic stage of children's drawing development levels. 2. The occurrence of Kopffusseler beings as scribbels. 3. The occurrence of Kopffusseler is formed according to certain process, and this is the result of the young child's process of inquiry. 4. One can find the theoretical foundations for the cause of occurrence of Kopffusseler from the differentiation theory of perception theory. Second. The researcher finds the following to be true about the form symbolism of Kopffusseler. 1. Kopffusseler form types can be divided into three Categories: a. Two legs and two arms attaching from a head. b. Two arms attached to 「a head with legs」omitted. c. Two arms attached either to the shoulders ot to the legs. 2. Through the discovery of 「the circle」and 「the stright line」in young children's drawings. We see that Kopffusselerhas those composition factors. 3. Kopffusseler is to very young children the perfect visual language expressing the human image. The symolic meaning of the circular figure is wholeness, and the srtraight line has the characteristics of direction and sensory perception.

불어 시청각 교재 및 교수법 개발

Nous avons essaye, dans cette etude, d'effectuer une comparaison sommaire des methodes audio-visuels entre De vive voix et Sans frontieres. De vive voix, paru en 1972, est une methode audio-visuel inspiree des recherches de la linguistique structurale. Cette methode invite a apprendre par coeur les dialogues comme modeles de langue par des exercices structuraux pour atteindre a l'objectif de communication. L'essentiel de la morphologie et de la syntaxe du francais est etudie dans ce texte selon une progression serree. La grammaire a souvent la forme d'un mecanisme grammatical a force des exercices structuraux. Mais ces exercices sont peu interessants, quelquefois trop enuyeux pour les etudiants meme s'ils donnent les notions de base de syntaxe. Par contre Sans frontieres est une methode qui a essaye de faire la synthese des approches structurales et communicatives. Du cote du structuralisme, on remarquera les dialogues audiovisuels, des exercices structuraux, de la grammaire explicite, des listes de vocabulaire. Du cote du fonctionalisme, on trouvera beaucoup de documents authentiques, jeux de role, exercices de creation. Cette methode nous fait entrer dans la realite francaise avec les documents authentiques, avec les vocabulaire actuel de tous les jours et nous fait connaitre les registres de langues francaises propres a chaque categorie sociale. Sans frontieres est une methode vraiment adapte au cours de conversation. Elle invite a faire parler, instruit en amusant et fait enfin arriver a communiquer en langue francaise.

허용학,백운봉,이완규,박휘립,정인현 한국산업안전학회 2002 한국안전학회지 Vol.17 No.4

User-friendly-web-based database system for searching creep property data was developed. This system includes about 38000 creep data for 270 different materials including low carbon steel, stainless steel and alloy steel. Data on creep rupture, creep deformation, creep crack growth and creeping materials can be searched through this system. Retrieved data is displayed in numeric form and also presented in graphical form for visualizing the data. Furthermore, the creep rupture data is designed to be fitted to a regression equation of logarithmic stress using time-temperature parameter(TTP). The degree of the regression equation, orthogonal polynomials, was determined using analysis of variance.

두 펄스 중첩법에 따른 펄스형상과 레이저 출력과의 상관관계

본 연구에서는 주펄스 및 중첩펄스로 구성되는 두 펄스 중첩 회로망을 설계하여, 그에 따른 펄스형상과 레이저 출력과의 상관관계를 조사하였다. 즉, 원 숏 멀티바이브레이터와 두 개의 SCR를 이용하여 펄스형 Nd : YAG 레이저의 계단펄스를 만드는 기술을 개발하였다. 먼저, 주펄스(6단메쉬)에 중첩펄스(3단메쉬)를 중첩시킨 실험을 통하여 레이저의 출력특성을 파악하였다. 두 펄스의 인가시간차인 지연시간 230μS이하의 범위 내에서 두 펄스 중첩법을 적용한 결과, 지연시간 0μS에서 최대출력(약 4.5%의 효율개선)을 얻었다. 따라서, 지연시간을 0μS로 고정하고, 전체 인가에너지를 50J로 하여, 주펄스 및 중첩펄스 3단-1단, 4단-2단, 6단-3단으로 구성하였으며, 그 각각에 대하여 펄스형상을 구하고, 출력특성을 비교하였다. 그 결과, 상승시간이 짧고, 피크치가 크며, 펄스폭이 짧을수록 더 높은 레이저 출력을 얻었다. In this study, it was designed two-pulse superposition network consisting of the main pulse and the superposition pulse, and it was investigated the relationship of pulse shapes and laser output. Namely, we developed a technique forming the step-pulse shape of pulsed Nd : YAG laser by using one shot multivibrator and two SCRs. First, we have been carried out experiments which was superposed superposing pulse(three-mesh) upon main pulse(six-mesh) within 230μS of delay time (time lag of two pulses). We have obtained maximum output(efficiency improvement about 4.5%) in delay time 0μS. Therefore, we have fixed delay time 0μS and applied 50J as the whole energy, consisting of a one/three, two/four, three/sis(superposing pulse/main pulse), we have obtained pulse shapes respectively and compared output characteristics with one another. Consequently, the shorter rising time, the higher peak value, and the shorter pulse width are, the more laser output obtains.

본 연구에서는 기존의 타원형 cavity가 아닌 원형 cavity를 설계 및 제작하여 그 동작특성에 관하여 연구하였다. 그 결과 타원형 cavity 보다 다소 적은 레이저 출력 효율 2.1%를 얻었다. 원형 cavity는 타원형 cavity 보다 컴팩트하며 제작하기가 용이하고, 제작 단가가 저렴하다는 장점이 있다. 입력에너지, 입력전압 및 펄스 폭을 동일하게 했을 경우 주회로 병렬 메쉬회로수를 최적화하고자 한다. PFN 회로를 1단에서 8단까지 PSPICE로 모의시험한 전류파형과 실제 실험한 전류파형이 거의 일치하였다. 그 결과 500㎲이상의 펄스 폭에서 6단 메쉬가 최적의 병렬 메쉬라는 결론을 얻었다. In this study, we have deigned and manufactured not only a present elliptic cavity but also a circular cavity, and experimented the operational characteristics. As a result, we obtained the maximum efficiency of 2.1% that was not less than that of an elliptic cavity. A circular cavity is much more compact and is easier to be manufactured than an elliptic cavity. And it can be made at a low cost. When the input energy, input voltage, and pulse width were in the same condition, we tried to decide the optimization of the mesh number of a parallel-mesh circuit which was connected with main power supply. The PSPICE simulation waveform of PFP(Pulse Forming network) circuit ranging from 1-mesh to 8-mesh nearly corresponded with the real current waveform obtained through a practical experiment. From these experimental results, we obtained the result that 6-mesh was the optimal parallel-mesh circuit in case that the pulse width was more than 500㎲.

본 연구에서는 플라즈마 진단을 위한 측정용으로 소형 고출력 루비레이저를 설계·제작하였다. 필요한 목적을 달성하기 위한 광 여기 시스템으로서 직선형 제논 플래쉬램프와 단일 타원형의 공동을 채택하였다. 그리고 제작된 시스템에 대한 설계 파라메타 및 그 동작특성에 대하여 연구하였다. 최대 입력에너지 484J를 인가했을 경우 최대 출력 170mJ, 레이저 펄스폭 110㎲, 경사효율 0.09%를 얻었다. 이 레이저 장치에 Q 스위치 소자가 부착된다면, 플라즈마 진단용으로 사용될 수 있을 것이다. In this study, a compact high-power ruby laser has been fabricated for plasma disgnostics as a light source. In order to satisfy the required purpose, a linear Xe flashlamp and single elliptical cavity are adopted as optical pumping system. The desing parameters and operational characteristics have been investigated. It was found that the maximum output energy of 170 mJ, laser pulse-width of 110 ㎲ and the slope efficiency of 0.09% were obtained at the maximum input energy of 484 J. If Q-switch element is added to this laser system, this laser will be usd for diagnosing plasma.
