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.

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.

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.

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.

Two subjects, Science teaching method and Study of the subject matters, are established to let students have the ability to teach the elementary science. It is an overwthelming view that Science teaching method course are merely divided into the above-mentioned two subjects by the elevation from the junior college to the senior one. But the authors discussed this theme on the junior college to the senior one. But the authors discussed this theme on the viewpoint that Study of the subject matters, newly established, is the result reflecting the significance of the elevation, not just the division of Science teaching method course inaugurated in the junior college period. The subject matters in the elementary school should include the fundamental concepts to attain the goal of the subject. That is, the subject matters should include the learning contents with the educational significance. Therefore, Study of the subject matters is defined as studying what these contents may signify educationally. From these points of view, Study of the subject matters is: 1) the study intended for the subject matters of the elementary school. That is ① what the fundamental concepts are, ② how they are related each other, ③ what their educational significance is. 2) to study the educational significance of the other subject contents. 3) a study for establishing the pertinent goal and selecting the subject matters to attain this goal when the educational conditions, such as the actual state and environment of children, are given. The authors discussed about article 1) in this paper.

In elementary schools, the 'FREE-LEARNING DAY' program has very important roles and potential in several aspects in light of the anticipated future situations and social needs in which require various forms and opened approaches for children's learning. Children's motivation and excitement are usually high and so children are apt to learn and retain more on nature than in the classroom. Likewise, many phenomena can be explored in the field that simple cannot be brought into the classroom or laboratory. It was found that most teachers have many difficulties in implementation of the program, mainly because of poor materials, specific guidelines to consult, and self-confidence of themselves. In particular, the real natural environment provides opportunities to encourage children to develope their creative and critical thinking skills essential to problem solving. In addition, when this program is implemented successfully, science teachers can ensure the possibility of achieving the scientific literacy of children. Therefore, the key point is to make certain that children are challenged to conduct their own investigations in realistic problem situations. It should be kept in mind that the desired means and fundamental basis of this program is interdisciplinary, integral approach to learning.

This study is concerned with the minimum cost design of reinforced concrete retaining wall using strength design method. The constrained optimization problem is formulated in terms of seven design variables and sixteen constraints, with the material and construction cost as the objective function. The solution is derived by a feasible direction method using ADS. It is shown that the design variables are satisfied with all constraints and the design process are automatically treated by computer. Therefore, the minimum cost algorithm developed may be recommended to achieve the minimum cost design of reinforced concrete retaining wall.
