The purpose of this study is to inquire into social and cultural background of modernization and the new woman's life centered around a new woman and a dancer, Choi Seung-hee and its style. The study was carried out centered around analysis of content through photos of 179 pieces and a documentary DVD. We analyzed collected photo data and came to know various bobbed hair style, clear makeup style and Art-Deco fashion. Accordingly, Choi Seung-hee has external appearance as a new woman and we came to know she is a representative woman in Korea. Because she crossed over into North Korea, the study has not been actively carried out but if we consider Choi Seung-hee's influence over the dance world, her women's leader and fashion roles at that age, it is considered that the study on Choi Seung-hee's external style has a significant meaning.

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 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.

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 is to examine the roles and costume of Sodong as shown in the illustration of Choseon Delegation to Japan. Results of the study can be described as below. First, as shown in the illustration, Sodong played roles as Tongin and dancer. As Tongin, Sodong provided services or made errands for his seniors. In the other role, while, Sodong danced to comfort his seniors and show dances of Choseon to Japanese people. Second, Sodong wore Kwaecha over Sochangeui throughout his march with the delegation as Tongin. This is probably because the two clothes made him feel convenient and easily active. In both 1700s and 1800s, meanwhile, Sodong also wore Jikryeong and Cheolik. Third, Sodong wore Kwaecha over Sochangeui, or Danryeong and Nansam all the time when he navigated together with the delegation. When passing through Tsusima into the Japanese mainland, which meant starting international exchanges between Choseon and Japan, Sodong sticked to formality to the utmost by wearing Danryeong and Nansam. Fourth, Sodong wore Kwaecha over Sochangeui when he performed as dancer. The two clothes were also worn by Mudong during outdoor banquets in Choseon at that time. In addition, it is thought that Sodong wore Jikryeong, Danryeong and Nansam like when he marched or navigated together with Choseon Delegation.

Web tension control system recently have been applied to OLED(Organic Light-Emitting Diode), RFID of flexible material, e-Paper and PLED(Polymeric LED) and various web control algorithms have being developed for higher productivity and product quality These system need an accuracy model to design and implement controller. In this paper, the web tension control system with dancer roll is mathematically modeled. Mathematical model consists of 8 subsystems and each subsystems can be described as impedance structure which connected by velocity and tension. Mathematical model is different from the estimated model at high frequency range because of structure dynamics which is ignored on mathematical model. The estimated model is derived using ARMAX model. The controller is designed using the estimated model. The step response of the estimated model are compared with that of physical model for a validation of estimated model. The experimental results show a good match between them.

Converting technology has developed to print information for the decades. Recently, this technology (like gravure, gravure-offset) is rising as an alternative way for mass production of printed electronics such as RFID, solar cell. For the width of printing line is under 10 microns, registration error should be minimized less than several microns. Tension disturbance is main cause of registration error and this should be minimized before the substrate is transported into printing zone. With PI controller, it is possible to suppress the disturbance within 2% of operating tension. But register error appears more than 10 micron using PIcontroller considering noise. So LQG controller is needed as an alternative control method. In this paper, the comparision of PI and LQG controller in the converting machine including measured noise and tension disturbance is presented. It is shown that the LQG controller is more suitable for precision tension control in printed electronics.
