In performance art, actors on the stage play an important role. The purpose of performance art is not in producing expression of superficial or trite pleasure, but in presenting a source of philosophical catharsis regarding essence of a human life. It is actors' responsibility to bring such expression onto the stage. Performance art not only involves technical skills but should be a cultural expression to represent tradition, spirituality and identity of a nation. In Korea, performance art tends to follow Western methods of expression. It is desirable to set a future direction to further develop methodology of expression in performance art. As part of such effort, the research examines how the rhythm of traditional Korean dance and dimension of time and space in performance art are effectively visualized in their relation to "stage direction." The research illustrates characteristics and concepts of Korean dances in terms of inhalation in deliberate hypogastric breathing ("danjeon') and rhythms of exhalation (gutgeori, jajinmori, huimori). Also, the research aims to enhance dramatic effect on the stage, which is distinguished from presentation of ordinary actions, by emphasizing dimension of time and space in visualizing expression.

Purpose: Breathing can be controlled either unconsciously or consciously. In Asian countries, various conscious breathing-control techniques have been practiced for many years to promote health and wellbeing. However, the exact mechanism underlying these techniques has not yet been established. The purpose of this study is to explore the physiological mechanism explaining how conscious breathing control could affect the autonomic nervous system, brain activity, and mental changes. Methods: The coupling phenomenon among breathing rhythm, heart rate variability, and brain waves was explored theoretically based on the research hypothesis and a review of the literature. Results: Respiratory sinus arrhythmia is a well-known phenomenon in which heart rate changes to become synchronized with breathing: inhalation increases heart rate and exhalation decreases it. HRV BFB training depends on conscious breathing control. During coherent sinusoidal heart rate changes, brain ${\alpha}$ waves could be enhanced. An increase in ${\alpha}$ waves was also found and the synchronicity between heart beat rhythm and brain wave became strengthened during meditation. Conclusion: In addition to the effect of emotion on breathing patterns, conscious breathing could change heart beat rhythms and brainwaves, and subsequently affect emotional status.
