Hamlet의 "TO BE, OR NOT TO BE" 독백

전갑종 동아대학교 인문과학대학 영어영문학과 1994 동아영어영문학 Vol.10 No.-

Discussions of Hamlet's "TO BE OR NOT TO BE" soliloquy are almost as varied and divergent as interpretations of the play itself. Among the various discussions three basic approaches to the soliloquy prevail : one of these explains the speech as a consideration of either acting against King Claudius : the second reads the speech as a contemplation of suicide : and the third is some kind of compromise between -or fusion of- the first two, explaining, for example, that Hamlet think first about his revenge against Claudius, then examines the idea of suicide, and finally rebukes himself for losing "the name of action' Comparison with Shakespeare's other soliloquies indicates that the "TO BE OR NOT TO BE" is not the usual confidential, informative soliloquy but an overheard soliloquy which has the function developing an important thread of the plot, the element of feigned madness. And I suggested has the first line of the soliloguy be read relation to the situation before and after the soliloguy rather to the lines following the first line, which will interpret the first line as "to be so(true) or not to be so" and as related to the theme of appearance versos reality rather than as "to exit or not to exit." It is a passage in which the young prince desperately and brilliaintly attempts to veil his true purposes behind an "antic disposition,'. The awareness of the reality of evil underneath the appearance of good, which Shakespeare makes so important a part of his conception of character and dramatic structure that it becomes essential to the action and is reflected everywhere in the language and imagery - that awareness is bound to result in a brooding en death as the filial reality of all. Here too, Shakespeare was using for his dramatic purpose a familiar tradition, and whorl he makes Hamlet think continually of death, he deepens the theme of the difference between appearance and reality itself.

The Still Point와 寂靜과 道諦

정갑동 동국대학교 경주대학 1995 東國論集 Vol.14 No.-

Many Essays and works have been published to explain and evaluate T. S. Eliot's world of poetry clearly, but only a few critics and scholars have acknowledge the Indian themes reflected in his poetry. Some words and a passage are more or less explicitly quated from Hindu and Biddhist literature. In this paper, I have made an attempt to elucidate his literary world focusing on Indian Philosophies with a special reference to Buddhism reflected in his poetry. This paper compares the still point in Eliot's poetry with the Third Noble Truth, nirvana, and the Eightfold Path in Buddhism. The Third Noble Truth affirms that this dukkha-characterized life can be brought to an end ; that there is a way out of the apparently endless repeated cycle, and that another kind of life is possible, namely nirvana. The Fourth Noble Truth points to the means by which this freedom, this new life, can be achieved, that is, the 'way' of the Buddha, Eightfold Path. The word which corresponds to the Buddhist nirvana is the still point in Four Quartets. I believe is to arrive at nirvana, that is, the still point, in the world. His literary world cannot be properly understood without a consideration of the influence he received from the Indian philosophies, especially Buddhism.

The purpose of this paper is to construct model which can be applied to the plan for preventing the road traffic vibration, and to analyze the primary factor an character based on the road traffic vibration. The predicting model was developed by quantification theory type I and step wise regression analysis with traffic condition as descriptive variables and vibration - rating value as objective variable and each model was compared and evaluated. The major results of this paper may be summarized as follows : (1) The correlation coefficient between traffic volume and ?? was 0.93, 0.98. (2) The correlation coefficient between the number of large - size car and ?? was 0.9, 0.93. (3) The correlation coefficient between ?? was 0.9 Through any of the degrees of appraised value are used, there is no problem. But the value of appraisal must be laid down considering the relation to human life. (4) We can anticipate the road traffic vibration better using the quantification theory type 1 than the step wise regression analysis.

김갑수,신판식 嶺南大學校 環境問題硏究所 1998 環境硏究 Vol.18 No.1

대부분의 대도시에서 있는 도시고속도로의 가장 중요한 기능은 이동성이다. 그러나, 대구광역시 도심에 위치한 신천고속화도로의 교통흐름은 주변 간선도로의 교통과 불완전 입체교차형태로 이루어져 있어, 그 처리 방식에 따라 병목현상을 초래하고 있다. 본 연구는 신천고속화도로와 접속되는 접속교차로의 운용방법을 각각의 대안으로 나누어 분석하였다. 대안 설정은 접속 교차로에서의 좌회전 현시 유무에 의해서 좌회전 없음 (대안 Ⅰ), 신천대로 상에 좌회전 (대안 Ⅱ), 대동로 상에 좌회전 (대안 Ⅲ)으로 나누었다. 분석은 각 대안별로 신천대로 Weaving 구간에서의 주행속도 변화, 인접교차로의 U-Turn 구간 V/C비 변화, 접속교차로의 평균정지지체시간 변화, 차량의 주행비용변화에 초점을 두고 실시하였다. 분석결과 대안 Ⅲ이 가장 좋은 효과가 있는 것으로 나타났다. The most important function of the urban expressway is a mobility in most cities. However, traffic flows of Sin-Chun Urban Expressway in Tae-gu is deeply affected by its intersection-type and traffic situation of crossing arterial roads. For instance, bottleneck in Sin-Chun Urban Expressway is affected by these two reasons. This study analyzed the effectiveness of the operational methods of intersection divided into three alternatives on the Sin-Chun Urban Expressway. The alternatives are made upon the existence of left-turn phase : left-turn prohibition by the existence and the non-existence of left-turn phase on cross street (Ⅰ), left-turn on Sin-Chun Dae-Ro (Ⅱ), and left-turn on Dae-Dong arterial road (Ⅲ), respectively. Each alternatives was analyzed according to the change of Running Speed in weaving area, the change of V/C ratio in U-Turn area, the change of Average Stopped-Time Delay in cross street and the change of vehicle operating cost. The results of the analyses showed that the third alternative was most efficient than the other alternatives.

센서의 안정도와 감도를 개선시킬 수 있는 단일전극을 가진 열선형 마이크로 가스센서를 제작하였다. 일반적으로, 금속산화물 반도체를 이용한 가스센서는 히터전극과 감지전극의 두 개의 전극을 가지고 있다. 제작된 센서는 히터전극위에 감지물질을 형성하여 단일 전극을 가지는 구조를 가지고 있다. 히터와 감지전극으로 사용되는 Pt는 glass 기판위에 스퍼터링법으로 형성하였으며, SnO_2 감지물질은 제작된 Pt 전극위에 열증착시켜 형성하였다. SnO_2막은 lift-off 공정을 이용해서 패턴을 형성하고 1시간 동안 산소분위기에서 열산화하였다. 제작된 소자의 크기는 1.92x.1 mm^2 이다. CO 가스에 대한 감지특성을 조사한 결과 1,000 ppm에 대해 100 mV의 출력변화를 나타내었으며, 넓은 농도범위(0 ~ 10,000 ppm에서 선형적인 전압출력을 나타내었다. 또한 가스 반응 전과 반응 후의 전압출력을 비교해 볼 때, 1 % 이내의 편차를 나타내는 우수한 회복성을 나타내었다. Micro gas sensor with single electrode was proposed for improving stability and sensitivity, Generally, metal oxide gas sensors have two electrodes for heating and sensing. This fabricated new type sensor have only a single electrode by forming a sensing material onto heating electrode. Pt as a heating and sensing electrode was sputtered on glass and a SnO_2 sensing material was thermally evaporated on Pt electrode. SnO_2 was patterned by lift-off process and then thermally oxidized in O_2 condition for 1 hr., 600 ℃. The size fabricated sensor was 1.9 x 2.1 mm^2. As a result of CO gas sensing characteristics, this sensor showed 100 mV change for 1,000 ppm and linearlity for wide range(0 ~ 10,000 ppm) of gas concentrations. And the sensor shows a good recovery characteristics of 1 % deviation compared to initial resistance.

The purpose of this Study is to show the measures of decreasing traffic accident in Urban Freeway. So, this study divides accident factors into human factors, vehicular factors, and Road environment factors that affect to traffic accident seriously. The accident datas used for analysis is in Daegu Sin-cheon urban freeway from January in 1994 to December in 1995. The datas were analyzed by Hayashi's Quantification Theory Ⅱ. Over 70% of accident causes are inattention driving and close following. Most effective factor in the accident cause and accident type is “a direction of damaged car's when the accident occured", its partial correlation coefficient ar 0.35, 0.70 respectively. Above two results are from not knowing of traffic situation exactly. When the guidance of traffic situation is continually served to driver, the traffic accident will be decraese.
