본 논문에서는 전자 유도 법칙을 이용한 차량용 유도 전력 집전장치가 제안하였으며 전력 전송 특성을 개선하기 위한 전력 집전체의 몇 가지 설계에 관련된 개점을 제시하였다. 또한 다양한 공진 주파수로 동작되는 직렬 공진 컨버터와 연결하여 전력 전송 시스템의 해석을 나타내었다. 동작 주파수와 파라미터의 변동에 대한 시스템의 민감도가 고려되며, 유도 전력 전송 시스템에 있어서 전력은 코일이나 트랙의 형태인 1차 권선을 통하여 하나, 혹은 그 이상의 절연된 급전 코일로 전송된다. 본 논문은 유도전력전송의 집전장치의 구조를 기존변압기와 유사한 등가회로의 파라미터로 구성하고, 공극 및 권선을 고려한 1차, 2차측 파라미터를 설정하여 1차측 급전 주파수의 변화에 따른 집전특성에 대하여 기술하였다. In this paper, the inductive power collector using electromagnetic induction for vehicle such as the PRT(Personal Rapid Transit) system is suggested and son ideas for power collector design to improve tile power transfer performance are presented. And also, the analysis of the inductive power transfer system in conjunction with series resonant converter operating variable high frequency is shown. Of particular interest is the sensitivity of the complete system to variations in operational frequency and parameters. In inductive power transfer system electrical power is transferred from a primary winding in the form of a coil or tract to one or more isolated pick-up coils that my relative to the primary. The ability to transmit power without contact enables high reliability and easy maintenance that allows inductive power transfer system to be implemented in hostile environments. This technology has found application in many fields such as electric vehicles, PRT(Personal Rapid Transit) etc. But, low output power is generated due to a loosely coupled characteristic of the large air-gap. Therefore, we will show you various characteristic of inductive power transfer system as double layer construction of secondary winding, which was divided in half to increase both output current and output voltage, a model of power collector and parallel winding structure, a model of concentration/ decentralization winding and the effects of parameter and operational frequency variation.

Various research to reduce weight of a car is achieving. This research is tendencious to manufacture solid piston rod of shock absorber as hollow piston rod using friction welding. This study deals with the friction welding of SM45C to SM45C-Pipe that is used in car shock absorber, The friction time was variable conditions under the conditions of spindle revolution of 2,000rpm, friction pressure of 55MPa, upset pressure of 75MPa, and upset time of 2.0seconds. Under these conditions, the microstructure of weld interface, tensile fracture surface and mechanical tests were studied of friction weld, and so the results were as follows. 1. In tensile strength, the hole processing is better than non-hole processing. 2. When the friction time was 1.5seconds under the conditions, the maximum tensile strength of the friction weld happened to be 869MPa, which is 103% of SM45C's tensile strength and 91% of SM45C's Pipe. 3. When the friction time was 2.0seconds under the conditions, the maximum bending strength of the friction weld happened to be 1599MPa, which is 80% of SM45C's bending strength and 118% of SM45C's Pipe.

『다케토리 모노가타리』의 이중적 서술 구조와 연결 매개체

“Taketori Monogatari” introduces various stories such as ‘an eccentric person"s birth story’, ‘wife-obtaining fight story’, ‘derivation story’, and ‘fairy robe-related story’. Just as shown in the names, they could be divided into stories with realistic materials and stories with unrealistic materials. However, in the parts like ‘development and growth of Kaguyahime’ and ‘proposal and ascension of the emperor’ with the unrealistic materials, the narrators and characters do not show any self-awareness of the unreality as the story develops under the realistic sense. On the other hand, in the part like ‘five young nobles proposal’ which intentionally mixes the unrealistic materials in the real world, the clear perception of the unreality is built on. In order to combine the double-narrative structure stories for a Monogatari work, the author uses several connecting links such as ‘marriage’, ‘treasure in imagination’ shown in the legend, and ‘rumor’. And here, an ‘old man’ plays a role of mediator in tying stories into one. “Taketori Monogatari” has become an ancestor of Japanese novels by deriving diverse-types of novels. However, the novels that realistically handle unrealistic materials gradually decline, and only Monogatari based on the stories with realistic materials is inherited. “Taketori Monogatari” could be evaluated as a work playing the role of driving force in the transitional period from the unrealistic myths or stories to the Japanese-style reality novels, Monogatari literature.

영화 속 타자성 분석 - <포도나무를 베어라>를 중심으로 -

민병훈(Min, Byung-Hun) 한국영상제작기술학회 2021 영상기술연구 Vol.- No.35

Director Min Byunghun" s third feature film, < Pruning the Grapevine>(2006) has been constantly interpreted as a kind of growth period that young theological students cannot but undergo in the narrative stream of faith and salvation. It is very interesting to substitute a philosophical thought for an analysis on the film. The philosophical thought is the concept of Other(他者) stressed by E. Levinas. In the film, several beings as alter ego with "the Face of the Other" appear among a series of accidents in which Suhyeon, a theological student, again invokes a conflict with Sua, his exgirlfriend and comes to feel a sense of guilt. The film symbolically expresses the process in which the subject with falsity, fear and weakness genuinely ask for the Other"s or her forgiveness. Inner truths which have never been said are discovered with the technique of "Otherness" as the uncertain and unlimited world, since a mirror device reinforcing the three-dimensional characteristics of characters, and furthermore, a large Otherness world in which the characters are engaged with each other like toothed wheels and which therefore covers the whole space-time in the film were established. By analyzing <Pruning the Grapevine>, the Otherness-centered film, this study emphasizes a limit of the subject and the necessity of Other. In addition, only altruistic attitudes with which one can face and be responsible for things different from him/her does not allow him/her to recognize the world as a target to be conquered, but to progress toward the future. It can be also found that the communication with God, which we cannot predict, would begin, only if we are not afraid of God"s mask created by us and prune false grapevines.

비심인성 흉통 환자의 상부위장관내시경 소견

Noncardiac chest pain (NCCP) is defined as recurring angina-like retrosternal chest pain of noncardiac origin. Although gastro-esophageal reflux disease (GERD) is recognized as the most frequent cause of this disorder, the pathophysiology remains to be elucidated fully. In Western countries, upper endoscopy has limited value in the differential diagnosis of NCCP because most of the mucosal findings detected are consistent with GERD. By contrast, in Korea the prevalence of gastric or duodenal ulcers in NCCP patients ranges from 17.9 to 20.7%. Considering this high prevalence and the different treatment strategies for GERD and peptic ulcer disease, upper endoscopy should be included in the initial work-up for NCCP in Korean patients.

C1 esterase inhibitor deficiency is a disorder resulting from a qualitative or functional defect of the C1 esterase inhibitor. It is characterized by recurrent episodes of subcutaneous and submucosal swellings in any part of the skin and the respiratory and gastrointestinal tracts. Gastrointestinal symptoms such as abdominal pain are the dominant symptoms in about 25% of cases and sometimes make this condition misunderstood as surgical emergency, especially when ascites is accompanied. We experienced a case of C1 esterase inhibitor deficiency in a 35-year-old woman presenting with recurrent abdominal pain, ascites, and lower extremities edema. Her symptoms first occurred 8 years ago, and used to spontaneously resolve within 3 days. In laboratory finding, serum C4 and serum C1 esterase inhibitor showed reduced level of 3.2 mg/dL and 5 mg/dL, respectively. After treatment with danazol and tranexamic acid, no more recurrence of symptoms was observed during 2 months of follow-up period. (Intest Res 2007;5:73-76)
