Unavoidable Geometric Errors in the Side Walls of End-milled Parts
Kang Kim 대한기계학회 2007 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.21 No.1
A study for investigating the geometric characteristics of the side wall, which is generated by the flat end-milling process, is carried out through experiments and geometrical analysis. For this research, flat surfaces of prismatic parts are considered. It is assumed that the change of material removal per tooth causes the change of tool deflection. Under this assumption, it is verified that the milled surface geometry is directly affected by the amount of material removal per tooth. Analytical models for predicting the location, size, and depth of the geometrically defected zone are also developed.
Is She a Fiend? : Lady Macbeth's Part in Macbeth
Kang Kim 21세기영어영문학회 2007 영어영문학21 Vol.20 No.2
This paper aims to reconsider Lady Macbeth's part in Macbeth as the woman who solely devotes herself in the quest for power for her husband, not for manliness. The traditional Shakespearean scholarships of criticism toward Lady Macbeth have seen her as a fiend-like figure, a devil, or a scapegoat in the male-dominated society, or a symbol of the feminine subjectivity against all conventional prejudice surrounding the women. However, we can grasp in the play that Lady Macbeth's sense of selfhood depends on a traditional pattern of femininity-both wife and helpmate. Wishing to yield her womanhood, she wants to be close to Macbeth. She offers the best she has to her husband. Even she takes on his unethical will to power. So, her tragic flaws can be interpreted in terms of conventional virtues women had to possess. Although her greatest mistake is that she is too much obsessed with her duty to husband without any discrimination of conscience and morality, her consistent affection and sacrificial or oftentimes irrational support for her man, even if the results are proved wrong, should be understood and acknowledged in the name of love. We are virtually living in the world where men and women depend on each other. Shakespeare seems to describe the patterns of our lives more broadly and accurately through his two protagonists, Lady Macbeth and Macbeth in the play.
Modeling of the Axial Movement of Parts During Centerless Through-Feed Grinding
Kang Kim 대한기계학회 2003 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.17 No.7
There are two major differences between the centerless infeed grinding process and the centerless through-feed grinding process. One is an axial movement of work pieces, and the other is that several work pieces are ground simultaneously and continuously by through-feeding. Because of these dinff erences. through-feed ground parts inherently possess not only the roundness error but also the tapering error. The aims of the research reported in this paper are to examine this inherent tapering characteristic and to find the effects of grinding variables (center height angle, regulating wheel tilt angle, and shape of grinding wheel surface). To accomplish the objectives, experiments were carried out using two types of cylindrical workpiece shapes. Also, computer simulations were performed using the 3-D through-feed grinding model.
The Birth of Political Shakespeare: Ki Kukseo’s Hamlet Productions in the 1980s
( Kang Kim ) 21세기영어영문학회 2017 영어영문학21 Vol.30 No.4
This paper attempts to survey a series of experimental Hamlet productions under military dictatorship, when assassination, coup d’etat, usurpation, corruption, and state violence were daily realities in the 1980s Korea. When freedom of speech was curbed, Shakespeare’s old, foreign story was endowed with contemporary and local meanings, and became an apt vehicle of political reflection and social communication. This is localization in a more profound sense, not just dressing the Bard in drag or setting his plays to folk music and dance. The understanding Korean audience did not come to the theatre appreciate a Western masterpiece or to enjoy a polished performance, but to participate in an intellectually stimulating and emotionally disturbing experience. While Shakespeare’s concern in Hamlet is primarily about the royalty and nobility, the common people take center stage in these Korean adaptations―as bystanders, innocent victims, and maybe even involuntary accomplices, who see that the time is out of joint but feel incapable of setting it right. Thus recontextualized, Hamlet is a tragedy not of an individual or a family, but of the entire society afflicted by madness and terror. In a sense, the performance on stage is no more than a rehearsal, in preparation for real action outside the theatre.
