Antony and Cleopatra에 나타난 逆說的 技巧와 劇的構造의 特性

崔永道 牧園大學校 1991 論文集 - 牧園大學校 Vol.19 No.-

Shakespeare's Antony and Cleopatra is the most magnificent of all his plays. The verse is gorgeous the characterization is subtle and the construction is unique and elaborate. Antony and Cleoptable was probably written early in 1607 or late in 1606. So that it appars to have been the immediat, sequal to King Lear. In Antony andmore other experimented with rapid alternations. The play contains no less thanmore other experimented with rapid alternations. The play contains no less than Cleopatra Shakespeare was writing with delight, understanding and taste, and also with a new command of words, rhythms and imagery, In the language of King Lear and Macbeth there is a suggestion of deliberate, conscious experiment, espe-cially in the use of a more elaborate kind of imagery : in the other hand, in An-tony and Cleopatra the new technique has become instinctive. As being well known, Coleridge, S. T. praised very highly of the value of An-tony and Cleopatra on his Shakespeare criticism. Coleridge's assertion that in An-tony and Cleopatra Shakespeare followed history more minutely than in any other play might well be disputed. Especially in Antony and Cleopatra Shakespeare once more other experimented with rapid alternations. The play contains no less than forty two episodes, of which one only exceeds tree hundred lines, and twenty more other experimented with rapid alternations. The play contains no less than more other experimented with rapid alternations. The play contains no less than forty two episodes, of which one only exceeds three hundred lines, and twenty four are less than seventy five lines in length. Therefore Antony and Cleopatra is unique in dramatic structure and its dramaturgy. In this the Writer tried to seek the charateristics of Antony and Cleopatre in term of paradoxical expressions, paradoxical characters, and paradoxical structures. Our whole hearted response to the play, Antony and Cleopata recognizes both sides of the paradox, the abundant vitality as well as the inherent loss and limitatio. In stagecraft also, the contrast between Egypt and Rome were insisted upon. Egypt and Rome were thus opposed and contrasted throughout the play They represented contradictory schemes of value, contradixtory attitudes to, and interpretations of the universe. And so, whole play should be read with the opposition of Egyption and Roman values in mind Conclusively, The Writer would like to discuss the matter of evil and sin appeared in Antomy and Cleopatra. As we know, in King Lear, Shakespeare struggled with the problem of evil, and in Macbeth, he struggled with the problem of sin in a Christian universe. Neverthless, in Antony and Cleopatra, Shakespeare returns to the old problem: what are the positive bases of the good life? He finds them in the human affections, and also he finds that the human affections are deeply rooted in the sensual nature. Of course, Cleopatra was the symbol of these, and she was sensual even in death; for paradoxically, it is these Egyptian values which must survive death. On the other hand, Caesar's sins were deeper-rooted and more deliberate than the sins of Antony and Cleopatra. And Caesar's heart was entirely set upon the passing world. We recognize that Shakespeare in his last phase tried to show us his view point of the world and his philosophy of value to us. In Antony and Cleopatra Shakes-peare insisted that the Egyptian values need a Roman purgatory to fit them for survival, and they were cleansed, through adversity, of the taint of selfishness. Antony kills himself in order to rejoin Cleopatra whom he believes to be dead, while Cleopatra looks forward in the same way to their future reunion. At any rate, Shakespeare created a new view point of the world by virtue of the act of Antony and Cleopatra, and he realized the reconciliation of the different values in this play.

Effect of wave conditions on the performance and internal flow of a direct drive turbine

최영도,김창구,이영호 대한기계학회 2009 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.23 No.6

The purpose of the present study is to investigate the effect of wave conditions on the performance and internal flow of a newly developed direct drive turbine (DDT) model for wave energy conversion experimentally. All the experiments using the test turbine models are conducted in a 2-D wave channel. Monochromatic waves of various conditions of wave height and wave period are applied to the turbine performance test. The influences of turbine configuration on turbine performance are also investigated. Test results show that rotational speed, differential pressure, incident flow rate, maximum output power, and best efficiency of the turbine model vary considerably depending on the wave conditions. Installation of a front guide nozzle and a rear water reservoir to the test turbine improves the turbine performance. Large passage vortex occurs both at the front and rear turbine nozzles in turn through a reciprocating flow in the turbine passage.

Air Layer Effect on the Performance Improvement of a Cross-Flow Hydro Turbine

최영도,신병록,이영호 한국유체기계학회 2010 한국유체기계학회 논문집 Vol.13 No.4

The purpose of this study is not only to investigate the effects of air layer in the turbine chamber on the performance and internal flow of the cross-flow turbine, but also to suggest a newly developed air supply method. Field test is performed in order to measure the output power of the turbine by a new air supply method. CFD analysis on the performance and internal flow of the turbine is conducted by an unsteady state calculation using a two-phase flow model in order to embody the air layer effect on the turbine performance effectively. The result shows that air layer effect on the performance of the turbine is considerable. The air layer located in the turbine runner passage plays the role of preventing a shock loss at the runner axis and suppressing a recirculation flow in the runner. The location of air suction hole on the chamber wall is very important factor for the performance improvement. Moreover, the ratio between air from suction pipe and water from turbine inlet is also significant factor of the turbine performance.

Real-Time Hardware Simulator for Grid-Tied PMSG Wind Power System

최영도,한병문,이준영,장길수 대한전기학회 2011 Journal of Electrical Engineering & Technology Vol.6 No.3

– This paper describes a real-time hardware simulator for a grid-tied Permanent Magnet Synchronous Generator (PMSG) wind power system, which consists of an anemometer, a data logger, a motor-generator set with vector drive, and a back-to-back power converter with a digital signal processor (DSP) controller. The anemometer measures real wind speed, and the data is sent to the data logger to calculate the turbine torque. The calculated torque is sent to the vector drive for the induction motor after it is scaled down to the rated simulator power. The motor generates the mechanical power for the PMSG, and the generated electrical power is connected to the grid through a back-to-back converter. The generator-side converter in a back-to-back converter operates in current control mode to track the maximum power point at the given wind speed. The grid-side converter operates to control the direct current link voltage and to correct the power factor. The developed simulator can be used to analyze various mechanical and electrical characteristics of a grid-tied PMSG wind power system. It can also be utilized to educate students or engineers on the operation of grid-tied PMSG wind power system.

In order to integrate large amounts of variable generation resources such as wind and solar reliably into power grids, accurate renewable energy forecasting is necessary. Since renewable energy generation output is heavily influenced by environmental variables, accurate forecasting of power generation requires meteorological data at the point where the plant is located. Therefore, a spatial approach is required to predict the meteorological variables at the interesting points. In this paper, we propose the meteorological variable prediction model for enhancing renewable generation output forecasting model. The proposed model is implemented by three geostatistical techniques: Ordinary kriging, Universal kriging and Co-kriging.

최영도,Choi, Young-Do 한국마린엔지니어링학회 2006 한국마린엔지니어링학회지 Vol.30 No.2

Recently, greenhouse effect by $CO_2$ gas emitted by use of fossil fuel causes earth environmental problem. As a countermeasure of the global warming. micro hydropower under 100kW becomes the focus of attention for its clean and renewable energy sources. Newly developed micro positive displacement hydraulic turbine shows high efficiency and good applicability for the micro hydropoewer. The purpose of this study is to clarify the influence of leakage loss and effective head on the performance of the positive displacement hydraulic turbine for the further improvement of the turbine performance. The results show that the turbine. with a smaller side clearance. has much higher efficiency than that with bigger side clearance and it can sustain the high efficiency under the wider range of operation conditions. The turbine torque is proportional to the effective head and independent of the flow rate. The leakage is also dependent on the effective head but nearly independent of the flow rate.

극저비속도 원심펌프의 펌프성능 및 흡입성능 향상

최영도,쿠로카와준이치 한국유체기계학회 2006 한국유체기계학회 논문집 Vol.9 No.6

There are high expectations of improving the performance of a centrifugal pump in the range of very low specific speed which has been developed recently for the use instead of a conventional positive displacement pump. However, even though elaborated studies has been done for the pump intensively, the pump performance has not increased so much. Also, it is difficult to find detailed information from published literatures for suction performance of the very low specific speed centrifugal pump. Therefore, this study is aimed to improve the pump performance more and to make clear suction performance of the very low specific speed centrifugal pump. Recircular flow stopper is installed on the pump casing wall at the region of impeller outlet to improve the pump performance and J-Groove is also installed at the inlet of the pump casing for the purpose of suppressing occurrence of cavitation as well as improving pump performance. The result suggests that the simultaneous improvement of pump performance and suction performance of the very low specific speed centrifugal pump is possible by adopting optimum configuration of the recirculation flow stopper and J-Groove.1. 서 론* 요코하마국립대학 대학원 공학연구원

4-로브 헬리컬형 로터를 가진 용적형수차의 성능예측법

최영도,Choi, Young-Do 한국마린엔지니어링학회 2007 한국마린엔지니어링학회지 Vol.31 No.5

In order to extract small hydropower in the very low specific speed range of $n_s<10$, a Positive Displacement Turbine (PDT) has been proposed and steady performances have been determined experimentally. However, the suppression of large pressure fluctuation is inevitable for practical application of PDT. Therefore, present study adopted 4-lobe helical type robe to reduce the pressure fluctuation. The results show that 4-lobe helical type robe can be adopted to suppress the pressure fluctuation drastically. Moreover, efficiency and unit power of the turbine with newly proposed 4-lobe helical type lobe are higher than those of the turbine with 3-lobe straight type robe.
