This paper presents the analysis of the analysis of thrust characteristics of linear induction motors(LIMs) according to secondary reaction plate. LIMs are well known as high speed transport systems, which can obtain thrust directly without gears and links, or auxiliary mechanisms. A simple structure, easy maintenance, and less environmental pollution are advantages of LIMs. In transport systems using LIMs, the secondary reaction plate is an important design factor, because it has considerable impact on the cost of the railway as well as the performance of the LIMs. This paper deals analyzed the characteristics of linear induction motor used for moving the vehicle of container scanner. Thrust, efficiency and load characteristic were interpreted with FEM regarding two models whose material of secondary reaction plate was copper and aluminum. It suggested the interpretation of thrust, efficiency and power factor characteristic along slip and compared the operation ability of linear induction motor through characteristics analysis along the load.

김미정 ( Mi Jeong Kim ),임재택 ( Jea Tack Lim ) 한국어린이문학교육학회 2010 어린이문학교육연구 Vol.11 No.2

본 연구의 목적은 방정환이 ‘소년운동’ 차원에서 기획한 번안동화집인 『사랑의 선물』중 임의로 선정한 총 4편을 원작과 비교하여, 원작이 ‘어떻게’, ‘얼마나’, ‘왜’ 다르게 번역되었는지 원작에 대한 번역 일치성 및 개작의 중재 전략을 알아보는 데 있다. 연구 결과 방정환은 번역자로서 내용의 의도적인 첨가, 삭제, 수정의 방법으로 원작을 개작하는 과정을 수행하였다. 또한 이러한 개작은 화합, 자국화, 윤색의 중재 전략이 사용되었는데, 방정환은 이러한 중재전략을 통하여 첫째, 순수한 동심의 세계 존중, 둘째, 외래문화에 대한 주체적 수용, 셋째, 문학적 감성과 상상력을 통한 애국 교육 등의 세계관을 뚜렷이 드러내었다. 이에 본 연구를 통하여 방정환은 『사랑의 선물』번안을 통하여 외국 동화가 문학텍스트로서 가지는 문학적·심리적 가치를 그대로 어린이에게 전달하는 동시에 유교 전통을 극복하고 우리나라 현실에 맞게 아동존중사상을 농축하여 표현한 문화변용의 주체였다는 사실을 알 수 있었다. Bang Jeong-Hwan tried to transfer foreign fairy tales in itself which was worth of literary and psychological value as a literary text to children and simultaneously express realistically condensed ideological contents of DongHak through the adaption of Sa-rang-ui-Suon-mul(A Gift of Love). This study chose four sub-titles of the Sa-rang-ui-Suon-mul to investigate how, how much different, why these translations(adaptions) were different from original on the base of the level of fidelity to original and the intervention strategy. As the results of this study, Bang Jeong-Hwan as a translator performed the process of these translations as a significant difference from original by introducing the method of intensely insertion, elimination, modification. Furthermore, Bang Jeong-Hwan could attain the following three purposes and express a distinguishing his outlook on the world through these adaptations: 1) the respect for the world of pure child mind 2) the creative and independent acceptance of foreign cultures 3) the patriotic education through a literary sensitivity and imagination. As results of this study, we surely knew that Bang Jeong-Hwan was a main agent of acculturation by means of maintaining the literary value of original and realizing an idea of children respect.

Effect of Photoperiod, Temperature and True-leaf Stage in Bolting Rate of Chicory (Cichorium intybus L. var. sativus)

Lim,Jung-Dae,Seo,Jeong-Sik,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Yu,Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

Root chicory (Cichorium intybus L. var. sativus) is potential alternative medicinal and sugar crop which accumulates a high amount of linear polyfructan, inulin in its roots. A problem in root production is that over-wintered stock plants often flower. Once the plant becomes reproductive, stem elongation and root growth slows and floral buds arise from every node, rendering the plants useless for propagation. The objectives of this research was to examine the effectiveness of manipulating environmental factors containing photoperiod, temperature and number of leaf states. The experiment was performed in growth chamber to create two photoperiods (8 h, and 16 h) with three temperature regimes (5℃/3℃, 10℃/8℃, and 15℃/13℃ day/night temperature) for a total of six treatments on three type of true-leaf stage of plant. Data of bolting rate, shoot and root length, shoot and fresh weight was invetigated in each treatments. This is the first report on changes in bolting rate and shoots and roots production during a whole growing season and differences in the effect of cold and photoperiod treatment depending on the true-leaf stage of plant.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

인터넷을 활용한 초등 영어 수업의 구어 능력 향상에 관한 연구

임정완,구현정 大邱大學校 師範大學 附設 敎育硏究所 2009 學校敎育硏究 Vol.5 No.1

본 논문은 초등 영어 의사소통 능력의 향상에 그 초점을 맞추어 언어의 4가지 영역 듣기, 말하기, 읽기, 쓰기 영역 중에서 의사소통능력과 가장 관련 깊은 듣기, 말하기 부분 향상연구 방안에 초점을 맞추어 보았다. 총 72명의 초등학교 학생들이 본 연구에 참여하였으며, 각각 36명씩 통제반과 실험반으로 나뉘어 약 20주간 실험 관찰되었고, 실험 결과는 SPSS 12.0 으로 분석되었다. 각 과의 내용과 이에 부합하는 인터넷 자료 등을 통해 여러 번의 실험 수업을 거친 결과 학생들의 듣기, 말하기 실력이 향상되는 것을 지켜볼 수 있었다. 듣기와 말하기 실력의 향상 정도는 듣기가 말하기보다 조금 더 유의도에서 의미가 있었다. 즉 듣기가 말하기보다 실력 향상에 있어 조금 더 효과가 있음을 알 수 있었다. 학생들은 다른 매체들에 비해 쉽게 노출되고 또 그만큼 쉽게 즐길 수 있는 매체가 인터넷이라 보다 적극적인 자세로 수업에 임했다. 아직 저학년인 학생들이므로 지금의 영어에 대한 흥미도가 평생의 영어 실력을 결정 할 수 있는 만큼 이 시기의 흥미도는 절대적으로 중요하다는 것을 고려 해볼 때, 학생들이 흥미를 느끼며 동시에 실력까지 향상되어간다는 사실은 주목해 볼 필요가 있다. It is widely known that the Internet-based English teaching can be useful for students since it is not only a way of providing joy for them, but also a means of consolidating and extending their knowledge of the language. The purpose of this study is to investigate the effectiveness of the Internet-based English Teaching for Korean elementary schools students. For this purpose, a review of related literature was carried out to analyze various teaching methods using the Internet. Then the analysis of the elementary school students and curriculum that was performed in English classes was carried out. A total of 72 elementary school students participated in this study and they were divided into one comparison group and one treatment group, consisting of 36 students each. They were observed over 20 weeks and surveyed on their interests about learning English after the treatment was over. Before and after the treatment, students' spoken English ability in each group was also measured and analyzed by the use of SPSS 12.0. The findings of the study were as follows: First, the treatment group showed higher spoken English ability than the control group, especially in terms of listening ability. By being exposed to the Internet-based class activities, the treatment group had more opportunities to listen to and speak in English than the control group. Second, the students' interests about learning English significantly increased after being taught by the Internet-based class activities. In conclusion, it is recommended to design and apply the Internet-based English class that plays a positive role to improve oral English ability for Korean elementary school students.
