The key points of this paper are followings. 1. The Buddhist theory of transmigration and the Chinese theory of Yin-Yang school are applied to linguistics. Language transmigates like man. It has five cases: Subjective, Verb, Adverb, Adjective and Objective cases. Five cases are making sentences. As a result, we have three kinds of sentences. Subjective + Verb Subjective + Verb + Adjective Subjective + Verb + Objective Each case has two case-marks: Yin (-) and Yang(+) 2. English and Korean are of the same origin. English 'Number' is a wrong rule of grammar. 'An' is Yang and 'the' is Yin. Zero-article is Yang and '-s' is Yin. 3. Possessive case is the sentence of the primitive time. 4. Function-words are articles, prepositions, copula verbs, auxiliaries, subordinate conjuctions, suffix and prefix. 5. These function-words are originated from coordinate conjunctions: so, and 6. We have two generations of conjuctions. First generation: so se as Second generation: and or that 'se' is now extinct. Followings are originated from these conjuctions. 1) so se as--->is, -s, as 2) or--->are, -ere 3) and--->an, am, on in, -en, en- 4) that--->the, do, to at, -ed, de-

The purpose of this paper is to present a teaching and learning method using the historical documentary ‘History Channel e’ in order to effectively teach Korean history to Korean learners. This study was examined the importance of Korean history education for Korean learners and analyzed the research results. After examining the principles and methods of history education using documentaries, it was discussed how to use 'History Channel e' in Korean language education. ‘History Channel e' is worth using in history education for Korean learners, but it is effective to select and present some programs suitable for achieving Korean teaching and learning goals rather than using all contents, and 71 contents were selected and presented. One of them was developed and presented as a learner-centered and process-oriented teaching and learning method. Through the development of teaching and learning methods using 'History Channel e', it is expected that Korean history education for Korean learners will be effective. However, as it is still an early-stage discussion, it is important to continuously develop by reflecting various feedbacks through the actual usage in the classroom.

This paper considered optimization method of appending a shape on a disc in an attempt to improve corefunctions, which are inherent in flow characteristics. The paper also verifies the optimization method of appendageshape with a Class 150 200A Butterfly valve. Then the design of experiment (DOE) with an orthogonal array isperformed to analyze the effect of form parameters by grey relational analysis and analysis of mean (ANOM). Andthis study sets flow coefficient as an object functions for optimization, and the conventional disc model and theoptimal appendage shape on disc model are compared by computational fluid analysis. The paper concludes that anoptimal appendage shape on disc model achieves wider usability by a wider operating range. 본 연구에서는 버터플라이밸브의 고유 유량 특성을 개선하기 위해 회색 관계분석을 이용한 디스크 형상최적화 방안을 도입하였다. Class 150의 200A 버터플라이밸브에 대해 적용하여 그 유용성을 확인하였다. 부가물 형상 파라미터의 영향 분석을 위해 직교 배열을 이용한 실험계획법을 실시하였으며, 파라미터의 영향을 회색 관계 분석과 평균 분석을 이용하여 분석하였다. 최적화를 위한 목적함수는 유량 계수를 선정하였으며, 기존 디스크 모델과부가물 부착 모델에 대해 유동 해석을 수행하였다. 회색 관계 등급을 이용하여 평균 분석을 실시하였으며, 그 결과를 토대로 최적 형상을 결정하였다.
