This study was performed to identify the current problem of The National Qualification Examination for Dental Technician and to provide suggestion for improvement of The National Qualification Examination System. This study was based on the questionaries answered by the professors in the department of dental technology of college and the members of Korea dental technician's society. The result could be summarized in the following. 1. The examination should be held not only in Seoul but in other areas simultaneously. 2. Prepartation of The National Qualification Examination should be entrusted to a committee composed of selected members of The Korea Dental Technician Association and selected members of professors in the department of dental technology. 3. The carrving practical examination should be continued and the method of grading should be change to ensure fairness, objectivity and balance. Specially colored wax can be used to prevent cheating in test. 4. The examination on the subject of "The Introduction Dental Anatomy" should be different for dental technicians and dental hygienists. And the subjects need to be divided into "Dental Morphology" and "Oral Anatomy".

The aim of this research is to study the functioning of the peak variations at the end of the rhythmic groups in spoken french. For this purpose, the text '60 Voix, 60 Exercices', published by Hachette in 1988, was selected. This textbook is based on interviews with 60 persons who briefly speak in a monolog from on a subject of their choice. 500 hundred different groups were selected and submitted to the auditory judgment of six informants, three French natives and three Japanese natives who had studied French for at least three years. It was found, first, that there exists a tendency to a change of either rising or tolling intonation compared with the flat one, and second, that the rising intonation obtains a flirty good score of frequency compared with the two other, ones even if the examined sentences do not pertain to the strict classical types of interrogative or exclamative sentences or dialogs, where affectivity is so often an important factor.

The purpose of this study is to characterize body types of males in their twenties, and to provide information on body types of males by classifying them into groups. In addition, this study attempts to provide ways that can help improve the fit and coverage rate of ready-to-wear clothes by developing an apparel sizing system according to body types. 297 male subjects in their twenties participated in this study. 54 anthropometric and 35 photographic measurements were taken from each subject. After combining the body types of the front and the side into a whole body, we selected typical body types out of the combinations. It is shown that 84.64% of males in their twenties belong to the HI type, H/equation omitted/ type, X/equation omitted/ type, Xl type, Yl type, and HS type. To develop a new size system of clothes, the distribution of sizes was determined by using means and standard deviations for basic parts of each body type. Then, the most optimal sizes were selected separately for each body type to maximize the coverage rate.

This paper studies generator rescheduling technique for congestion management in power system with wind farms. The proposed technique is formulated to minimize the rescheduling cost of conventional and wind generators to alleviate congestion subject to operational line overloading. The generator rescheduling method has been used with incorporation of wind farms in the power system. The locations of wind farms are selected based upon power transfer distribution factor (PTDF). Because all generators in the system do not need to participate in congestion management, the rescheduling has been done by generator selection based on the proposed generator sensitivity factor (GSF). The selected generators have been rescheduled using linear programming(LP) optimization techniques to alleviate transmission congestion. The effectiveness of the proposed methodology has been analyzed on IEEE 14-bus systems.

This is the premise that the language's cultural understanding must preceded the process in order to facilitate the communication of foreign languages. In order to understand the contemporary social culture of Korea and China, we sued the film 'Simple Life 'to conduct Chinese cultural education. For this, we first selected the theme of the culture, which is an issue in the modern society that appears in the film. Using the ambassador in the movie 'Simple Life",questionnaires and classes based on the culture selected for the subject were sometimes divided among the students of the Korean and China, and sometimes shared opinions and discussions and communication. The result of such a class progression are as follows: understanding the context of the culture and the use of movies can help you communicate smoothly.
