漢文敎科書를 통해 본 語文敎育의 考察 : 中高敎科書의 編成을 中心으로
曺斗鉉 圓光大學校 1982 論文集 Vol.16 No.1
This thesis is designed to study linguistic and literary education surveyed through Chinese Classics textbooks. In all the educational activities teaching materials as well as normal textbooks are regarded as an important matter. Chinese Classics education is not an exception. Therefore, they must be constantly analyzed, examined and revised to make them better ones, and make them contribute to Chinese Classics education. From these points of view, two kinds of Chinese Classics textbooks of junior High school, five kinds of senior High school I, and three kinds of senior High school Ⅱ, were closely analyzed and evaluated. It's seemed to be a difficult talks for the compilation and edition junior High schools as well as senior High schools because 1800 characters of Chinese Classics must be accorded with the ratio by each school year. Chinese Classics texbooks of Junior High School and Senior High School I are apt to be mixed up with Chinese Characters and phrases because they have to be compiled after a deep consideration of the allocation of Chinese characters. Of course, it is with certain that units of Chinese characters and phrases have been selected from characters in every day use practivally and educationlly and have been compiled in accordance in accordance with the level of school year, but in order to increase the efficiency of Chinese Classics education, close research and constant revision must be accompanied. It is firmly believed that the Ministry of Education is taking gradual steps to revise it after a careful consideration of on-the-spot investigation, research of scholastic field, and public opinions. The writer is going to summarize what has been mentioned until now, and then to make a conclusion presenting some problems to make a desirable Chinese Classics education. (1) It is highly recommended that chinese classics education be started from the its school year of primary schools, and be taught 900 Chinese characters during six years of its course. (2) About 900 Chinese characters must be taught during the three years of junior High school course, thus learning all of 1800 Chinese characters completely during the school and junior High school courses. (3) Textbooks of hish level Chinese Classics must be organised and compiled independently. (4) Even in junior Hish school classes, simple grammar lesson must be established as subjects and grammar must mixed be organixed in senior High school textbooks to arrange them entirely. (5) Graduates of Department of Chinese Classics Education seem to be adequate to be in charge of Chinese Classics course. (6) Chinese Classics class hours must be extended from present one hour to more than two hours a week. (7) Items of examination problems of Chinese Classics must be extended and marking points have to be accorded with other subjects in the state run qualification examination for colleges as well as high schools. (8) In other subjects outside of Chiness Classics course, 1800 Chinese characters must be taught. It is writer's firm belief that when all the aforementioned problems are settled the compilation of Chinese Classic textbooks will be normalized and goals of Chines Classic education will be sccomplished properly. It is writer's firm belief that when all the aforementioned problems are settled the compilation of Chinese Classics textbooks will be normalized and goals of Chinese Classics education will be accomplished properly.

염료감응형 태양전지를 위한 고분자 전해질막에서의 가소제의 효과
조두현,정유영,윤미혜,권소영,구자경 한국막학회 2010 멤브레인 Vol.20 No.1
Using poly(ethylene oxide) (PEO) as a polymer host, poly(ethylene glycol) (PEG) as a plasticizer, potassium iodide and iodine as sources of I - /I3 - , PEO-PEG-KI/I2 polymer gel electrolytes were prepared. Based on the polymer gel electrolytes, solid-state dye-sensitized solar cell(DSSC)s were fabricated. The content of PEG in the electrolyte was changed from 0 to 85%. The electrolyte showed self-supporting form through whole range of the PEG content. As the PEG content increased, the ionic conductivity and I3- diffusivity increased and the light-to electrical energy conversion efficiency increased under irradiation of 100 mWcm -2 simulated sunlight. 염료감응형 태양전지를 위한 고분자 전해질막을 제조하였다. 고분자물질로는 Poly(ethylene oxide) (PEO)를 사용하였으며, 가소제로서 poly(ethylene glycol) (PEG)를 첨가하였고, 전해질염 및 I - /I3 - ,의 공급원으로서 KI 및 I2를 첨가하여 고분자 전해질막을 제조하였으며, 이와 같은 고분자 전해질막을 바탕으로 염료감응형 태양전지를 제조하였다. 고분자 전해질 내의 가소제로서의 PEG 함량은 0%에서 85%의 범위로 변화하였다. 이러한 PEG 함량 전 구간에서 고분자 전해질막은 그 형태를 자체적으로 유지하는(self supporting) 완벽한 고체 전해질막의 형태로 제조되었다. PEG 함량이 증가하면서 전해질막을 통한 이온전도도와 I3- 이온의 확산도계수는 증가하였다. 염료감응형 태양전지에 있어서는 고분자 전해질막 내의 PEG 함량이 증가하면서 그 효율이 증가함을 볼 수 있었다.

실도로환경에서 3D LiDAR 센서와 정밀 지도를 이용한주변 차량의 추적 및 주행차로 인식기법 연구
조두현,안경재,강연식 제어·로봇·시스템학회 2019 제어·로봇·시스템학회 논문지 Vol.25 No.5
This paper presents a tracking and lane recognition method for nearby vehicles using a 3D LiDAR sensor and a high-precision digital map to improve the safety of autonomous vehicles. A multiple-object tracking system based on a Kalman filter was developed using an Integrated Probabilistic Data Association Filter (IPDAF). The driving lane of nearby vehicles was able to be identified by transforming their relative position into a global position on a pre-constructed high-precision digital map including many of the characteristics of the road. By incorporating the lane information of the nearby vehicles into the global path planning of the ego-vehicle, early decision-making was made possible for a collision-free vehicle control strategy. The developed approach was verified using realistic experimental scenarios in a public road environment.
