Objective: The purpose of this study was to investigate the effects of squat exercises using elastic bands of ballet dancers on muscle activity, arabesque angle, and static balance of ballet dancers during arabesque posture. Design: A randomized controlled trial Methods: A total of 25young female ballet dancer svoluntarily participated in the study. The participants were randomized to the elastic resistance squat group(n₁=13) and body squat group(n₂=12). The squats exercise was applied to a total of 12 exercises per four weeks and consisted of 15 times per one set in one to two weeks, 4 sets in three to four weeks. All subjects were evaluated muscle activity, arabesque angle, and static balance during arabesque posture at before-after intervention. All participants were measured muscle activity, arabesque angle, and static balance during arabesque posture at before-after intervention. Results: Elastic resistance squat group and body groups showed a significant increase in the muscle activity, angle, and static balance ability during arabesque posture(p<0.05). In the comparison between the groups, the elastic resistance squat group showed a significant increase in muscle strength, angle, and static balance during arabesque posture (p<0.05). The results showed that the elastic resistance squat exercise was more increased than the body squat exercise in all variables (p<0.05). Conclusions: Therefore, when planning a training program for a ballet dancer, the elastic resistance squat movement can be applied as an exercise method to improve the muscular performance and balance ability of the ballet dancer.

The purpose of this study was to analyze relating with Faucult's disciplinary power which factors influence a dancer's self-management (weight control)Total 10 ballet major undergraduate students of two respective universities in Seoul and Daijon were selected for the research and the chosen method was an interview with them. After the researchers analyzed the interview result, they found out the following several significant results. The first reason that major ballet dancers control their weight is to show their beautiful figures on the stage and to make their appearances look slender in the mirror. Dancers adapt various methods for effective weight management (diet control) such as dietary control, 1 food intake (potatoes, bananas, grapes, etc), physical force to advise or ingest (injection, taking medicines, reflexology, vomiting, etc.) Then, what is the hidden vision that makes such a practice of weight control maintain? The study presents a "mirror" as a tool of control playing a significant role, in terms that the power of discipline functions automatically in a dancer's body. In addition, another constant factor of dancers' weight management is monitoring each other's performance continuously, which is called "synopticon" Symptoms. Lastly, the fact that a question about placing a ruler could function in the continuous practice was also revealed.

Objective: The objective of this study is to present a scientific basis for ballet dancer training methods by analyzing the relationships between subjective assessment of the ballet movement 'Grand pas de chat' and kinematic and electromyographic factors. Method: The subjects were 14 professional dancers with 15 years of experience on average. Four cameras and a wireless electromyogram were used to examine kinematic factors, and the filmed videos were analyzed by 3 experts for subjective assessment. Results: Although no differences in kinematic factors were found between the excellent dancer group and the non-excellent dancer group divided based on the experts' assessment, some difference was found in electromyographic factors, especially in relation to the gastrocnemius muscle, rectus femoris muscle, and erector spinae muscle. A relationship between subjective assessment and kinematic and electromyographic factors was found, and factors such as right-side rectus femoris activation, time required, left-side gastrocnemius activation, and front-back displacement affected subjective assessment. Conclusion: This study showed a relationship between subjective assessment and kinematic and electromyographic factors. To receive higher scores in subjective assessment, it is necessary to extend the hang time by using the lower limb muscles. The findings of this study also indicate the necessity of weight training in order to improve dancing techniques.

The purpose of this study was to investigate the effects that breathing, thoracic and abdominal, had on the smoothness while performing ballet pour de bra. Five skilled ballet dancers(age: $24{\pm}1$, height: $163.4{\pm}2.88$, weight: $44.4{\pm}1.34$) with experience of over 10 years participated in this study. Each participant performed the ballet movement three times with abdominal respiration and with thoracic respiration. The kinematic data was recorded at 60 Hz with three digital cameras (Sony VX-2100). The pour de bra movement consists of two phases, up and down. The up phase is defined as the movement from the en bas through the en avant to the en haut. The down phase is defined as the movement from the en haut through the $\grave{a}$ la seconde to the en bas. During these two phases the Jerk Cost (JC) factor was calculated for the shoulder, elbow and wrist to quantify the smoothness. The group who performed the movement while abdominal respiration had a lower JC factor and so it was concluded that while abdominal respiration the smoothness of the movement was increased as opposed to the thoracic respiration.

Objective: The purpose of this study was to investigate the effects of neuromuscular training of ballet dancers with chronic ankle instability on ankle stability and posture controlability. Design: A randomized controlled trial. Methods: A total of Thirty-twoyoung female ballet dancers with chronic ankle instability have voluntarily participated in the study. The participants were randomized to the neuromuscular training group(n₁=11), elastic resistance squat group(n₂=11), and control group(n₃=10). The intervention was applied to a total of 18 exercises per six weeks and conducted in each group for one hour a day, three times a week. All subjects were evaluated for Cumberland ankle instability tool(CAIT), static balance at before-after intervention. Results: In the comparison of the effects within the groups, the effect of the intervention on CAIT and posture control was significantly increased in the neuromuscular training group and elastic resistance squat group (p <0.05). In the comparison of the effects between the groups, the neuromuscular training group, and elastic resistance squat group were found to significantly increase more than the control group (p <0.05). The effect of ankle stability is similar in neuromuscular training and elastic resistance squat training, neuromuscular training is more effective in improving posture control rather than elastic resistance squat training. Conclusions: When planning a rehabilitation training program for a ballet dancer with chronic ankle instability, neuromuscular training can be applied as an intervention method to improve ankle stability and posture control ability.

Character dance not only improves the expressive power of ballet majors, dancer and choreographers but also breathes life into the performance. Character dance, which has comprehensive educational implications, was difficult to conduct research due to lack of materials and incompleteness in the field of ballet education. Even popular concepts were not established. In order to establish the meaning of the character dance, this research examined the history of character dance from the Middle Ages to the present and the meaning and the category were also schematized. Also, I tried to find out the direction of development. Character dance through systematic categories and meaning establishment can provide extended educational forms to infants and children as well as dance majors and non-majors. This research of character dance is expected to provide basic materials not only for the ballet education but also for the various educations. Lastly, the author of this research is expecting that detailed researches will be conducted in the future.

In this research, we conducted an experiment on evaluating the extending depth information method and surface reconstruction method and the interaction of these two methods in order to enhance the final intermediate view images, which are acquired using DIBR (Depth-Image-Based Rendering) method. We evaluated the experimental control groups using the Microsoft's "Ballet" and "Break Dancer" data sets with three different hole-filling algorithms. The result revealed that the quality was improved the most by applying both extending depth information and surface reconstruction method as compared to the previous point clouds only. In addition, it found that the quality of the intermediate images was improved vastly by only applying extending depth information when using no hole-filling algorithm.
