The object of this study is to analyze the dynamic characteristic of lateral damper for the railway vehicle. The vibration characteristics are studied from eigenvalue analysis for critical velocity, and frequency analysis for the effects of the damper. Critical velocity of the model passenger car is found to be a) 20 m/s for damping force of 0 kg s/m, b) 64 m/s for damping force of 1,500 kg s/m, c) 60∼74 m/s for damping force of 730∼2,500 kg s/m. In high speed running, damping force should be decreased for high critical velocity. Lateral damping force should be greater than 730 kg s/m for stable running.

This study was conducted to establish the cultural techniques of the puddled-soil drill seeding of race (Oryza sativa L.), which is one of the efficient labor saving cultural methods, in the central part of Korea. Seoanbyeo was seeded at three times from April 10 to May 20 with the 20 day interval in 1994. The number of seedling stands per m2 at each seeding date were 50, 90, 130 and 170. The tillering characteristics, lodging characters, dry matter production, yield components and yield were investigated. The number of days to the maximum tillering stage was reduced at the later seeding date. It was 70, 55 and 25 days in seedings on April 10, April 30 and May 20, respectively. The critical effective tillering stage was also shortened at the delayed seeding. The higher the number of seedling stands was, the higher number of tillers, the shorter duration to the maximum tillering stage and the earlier critical effective tillering stage were resulted. The number of tillers was higher at the earlier seeding date. The number of tillers was increased in the order of 50, 90, 130 and 170 seedling stands per m2. The ratios of effective tillers were 53, 61 and 63% at seeding on April 10, April 30 and May 20, respectively. The ratios were not significantly different at April 10. But the ratios in seeding on April 30 and May 20 were reduced as the number of seedling stands was increased. The weight of stem base related to lodging was the highest with 2.01g/10 plants in the optimum seeding on April 30, while it was 1.59g/10 plants in the late seeding on May 20. It was also decreased as the number of seedling stands was increased. The dry weights at 30 days before the heading stage were increased at the later seeding, while the dry weight at the heading stage was the highest at seeding on April 30 which is considered as the adequate seeding time. The dry weights at 30 days before the heading stage were increased as the number of seedling stands was increased and they were increased up to 130 seedling stands per m2 at the heading stage. The length of panicle exsertion was shortened at the later seeding. The length of panicle exsertion was increased up to 130 seedling stands. but it was shorter at 170 seedling stands. The heading dates were later at seeding on April 30 and May 20 than at seeding on April 10. They were not remarkedly different among seeding dates at 50 seedling stands, it was earlier at the higher number of seedling stands over 90. The number of spikelets per panicle was decreased at the higher number of seedling stands. The ratio of ripened grains was higher at earlier seeding than at later seeding. It was not significantly different among the number of seedling stands at the same seeding time. Yields at seeding on April 30, April 10 and May 20 were 644, 624 and 551kg/10a, respectively. The seeding on April 30, the optimum seeding time, resulted the highest yield. Rice quality was decreased due to the increase of the green kerneled rice as the seeding date was delayed.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

초음파 공명 분광법(RUS)을 이용한 SiC 입자강화 Al 기지복합재료의 탄성계수 해석

홍순형,주영상,정용무,정현규 韓國非破壞檢査學會 1999 한국비파괴검사학회지 Vol.19 No.3

SiC 입자강화 2124Al 금속복합재료의 강화재 부피분율에 따른 탄성 stiffness를 초음파 공명 스펙트로스코피(resonant ultrasound spectroscopy: RUS) 방법을 이용하여 측정하였다. RUS 방법은 한 개의 소형 시편으로 9개의 독립변수를 가진 사방정계(orthorhombic) 탄성계수를 간단한 실험으로 측정가능함을 보여주었다. SiC 강화재 부피분율 변화에 따른 탄성계수를 측정하였는데 이 경우 초기 추정 탄성계수를 구하기 위해서 부피분율에 따른 미세조직 사진으로부터 강화재의 형상(aspect ratio)과 방향을 고려한 유효 aspect ratio 개념을 도입하였고, Mori-Tanaka 이론식에 의한 계산결과를 이용하였다. 이로부터 계산된 공진주파수와 RUS의 측정 공진주파수 사이를 최소화함으로 정확한 탄성계수를 측정하였다. 측정된 stiffnesses로부터 공학적 탄성계수인 Young's modulus를 계산하였으며, 계산된 Young's modulus와 압출방향으로 인장시험한 Young's modulus를 비교분석하였다. SiC 입자의 부피분율이 증가함에 따라 탄성계수가 증가함을 나타내었고, 탄성 stiffness의 거동은 강화재가 많이 첨가될수록 횡등방성(transversely isotropic) 이 강하게 나타났으며 이것은 압출공정에 의해 강화재 입자의 방향성 재배열에 기인한다. 한편 일정크기 시편에 있어서 기본 공진주파수가 강화재 부피분율에 따라 고주파수 영역으로 이동하는 현상이 관찰되었으며, 이로 부터 비파괴적으로 강화재 부피분율을 예측할 수 있는 가능성을 제시하였다. The dynamic elastic properties of metal matrix composites were investigated by resonant ultrasound spectroscopy(RUS). The composites used in this study consisted of 2124 aluminum alloy reinforced with different concentrations of SiC particles. RUS can determine the nine independent elastic stiffness(C )for the orthorhombic symmetry on a small specimen simultaneously. The elastic constants were determined as a function of the volume fraction. A concept of effective aspect ratio, which combine the aspect ratio and the orientation of reinforcement, was used to calculate the initial moduli from Mori-Tanaka theory for the input of RUS minimization code. Young's moduli can be obtained from the measured stiffnesses. The results show that the elastic stiffness increases with increment of the particle content. The behavior of elastic stiffness indicates that the particle redistribution induced by the extrusion process enlarges the transversely isotropic symmetry as the fraction of reinforced particles increase. This relationship could be used for determination of the volume fractions of reinforcement as a potential tool of nondestructive material characterization.

Updike 소설의 여성들 : Rabbit, Run

洪性用 조선대학교 인문학연구소 1995 外國文化硏究 Vol.18 No.1

20세기초 미국 소설 문단은 풍미케 한 William Faulkner와 Ernest Hemingway의 쇠퇴로 인한 공백상태가 1960년에 이르러 두드러지게 된 것이 사실이다. Hyman은 이와같은 공백상태를 메꾸어 줄 작가로 Updike를 꼽고 있다. 1968년에 Rabbit, Run이 출간되자 그는 Updike를 a first-rate intelligence, a considerable learning, an impressive honesty and a true creative imagination를 지닌 "the most gifted yound writer in America"이라고 극찬하고 있다. 이와 같은 찬사는 Updike가 그의 남성 주인공을 통하여 그들의 정신적 만족의 추구내지는 현대사회에서의 절망의 좌절을 경험한 나머지 심오한 종교적 추구에 그의 주제를 두고 있음을 찾아볼 수 있다. 튻히 간과할 수 없는 사실은 이들 남성 주인공들의 탐색들 성과 관련시킴으로써 작중 여성들의 성적인 면에초점을 맞추고 있다는 것이다. Updike의 생에서 여러 요인들 즉 출생지, 주위 사람들, 그리고 그에 따른 여러 사건들이 그의 작품에서 평행을 이루고 있으며 여인들에 대한 그의 태도에 적잖은 영향을 미친 것이 분명하다. 그는 자기의 고향은 그가 1932년에 출생했던 Pennsylvania주 Shhillington을 "the center of the nation"라고 말하며 그에 대한 역사와지리에 대하여 상술하고 있다. 일례로 자기가 어렸을 때 살던 거리의 끝에 자리잡고있던 구빈원을 이렇게 말하고 있다. AT the end of our street there was the County Home-an immense helelow poorhouse, set among the wide orchards and lawns, surrounded bu a sandstone wall that was low enough on one side for a child to climb easily, but that on the other side offered a drop if twenty of thirty feet, enough to kioo you if you fell... The poorhouse impinged on us in many ways. For one thing, my father, whose favorite nightmare was poverty, often said that he liked living so close to a poorhouse, if worse came to worse, he could walk there. For another, the stench of the poorhouse pigs, when the wind was from the east, drifted well down Philadelphia Avenue.(AP.156) 이처럼 Updike 소년시절의 주위환경은 그의 소설이나 단편소설의 배경으로 이용되고 있다는 점에서 유의할 만하다. 위에서 인용되고 있는 구빈원은 그의 첫 소설 The Poorhouse Fair의 배경을 이루고 있다. Updike는 작품을 통하여 자기의 어릴 적 환경을 강조하고 이때의 그의 개인적인 생활을 상세히 제시하고 있다. 그는 자신을 "a small twon child", "not a very darling"이라 말함으로써 그의 부모나 조부모와 함께 자라난 어린애에 불과했음을 시사하고 있다. 비록 그가 조부모와 함께 계속 생활 했지만 그들에 대해 기억나는 바는 별로 없고 자기 조부로부터 정치적 영향을 받았음을 단적으로 언급하고 있다. "My grandfather lived for ninety years, and always voted and always voted straight Democrat" 또한 할머니는 아주 미신적이고, 구식이며, 어떤 면에서는 "wild" 했던 것으로 회상하고 있다. My grandmother was always muttering little things; she came from a country world of spilled salt and cracked mirrors and new moons and omens. She convinced me, by contagion, that our house was haunted; I punished her by making her stand guard outside the bathroon when I was in it. If I found she had fallen asleep in the shadowy hallwau crawling with ghosts, I would leap upon her back and pummel her with a fury that troules me now.한편 Updike는 가족에 대한 그의 감정을 나타내고 있는데 자기 아버지에 대해 "a conscientious man, a school teacher and deacon, and also, somehow, a man of the streets"라고 기억함으로써 호의적인 태도이며, 그의 아버지의 직업을 자랑스럽게 여겼다. My father's job paid him pooly but me well, it gave me a sense of, not prestige, but place. As a schoolteacher's son, I was assigned a role; people knew me. When i walked down the street to school, the houses called, 'Chonny'. I had a place to be 또한 그는 자기 아버지와 Shillington 남쪽의 숲속을 거닐었던 일들을 애증의감정으로 이렇게 술회하고 있다. Every Sunday afternoon that was fair, we would set out, sun, birds, treetop cruising above us as we made our way. -- I would lag farther and farther behind, until my father would retrace his steps and mount me on his shoulders Updike는 그의 수필집에서 어머니에 대하여는 많은 이야기를 하지 않고 있다. 허짐나 그의 어머니는 그의 어릴 적 행동 하나하나를 간섭하고 제약을 가한 엄격한 여인상으로 제시되고 있다. Twice, in my childhood, the poohouse barn burnt, and I remember my father rushing out of the house in the middle of one night, and my begging to goand my mother keeping me with her, and the luckier, less sheltered children the next day telling me horrific tales of coocked cows screamign horses. And I continued to do it every day . . . until a neightbor told my mother, and she, with a soldmn weight that weemed unrelated to the airy fact, forbade it
