People today belong to many different subcultures and have diverse interests. Their job no longer defines who they are, while their pastimes can be a bigger reflection of their inner self. This article examines swing dancers in Korea, and focuses on their self-identity and how they express this through clothes. Based on in-depth interviews, observations and photographs of swing dancers with different day jobs, the study results find that most of the subjects intentionally incorporate swing dance cues in their daily work wardrobe, and that this makes them feel more comfortable, honest and satisfied with their job and identity, both as a swing dancer and working professional.

To implement Argentina tango dancer-like walking of the humanoid robot, a new trajectory generation scheme based on particle swarm optimization of the blending polynomial is presented. Firstly, the characteristics of Argentina tango walking are derived from observation of tango dance. Secondly, these are reflected in walking pose conditions and cost functions of particle swarm optimization to determine the coefficients of blending polynomial. For the stability of biped walking, zero moment point and reference trajectory of swing foot are also included in cost function. Thirdly, after tango walking cycle is divided into 3 stages with 2 postures, optimal trajectories of ankles, knees and hip of lower body, which include 6 sagittal and 4 coronal angles, are derived in consequence of optimization. Finally, the feasibility of the proposed scheme is validated by simulating biped walking of humanoid robot with derived trajectories under the 3D Simscape environment.

Requested from the Andong MBC station to do visualization work on hahoe Pyulshin-gut (Hahoe Mask Dance Drama) of Hahoe village, the traditional cultural asset of Andong Province, as a part of specialization project for local cultural asset, this study describes the work process and result for about 3 months from June 1, 1998 to August 20, 1998. In addition, this study describes the data collection at the fundamental preliminary research stage, analysis process and full-swing artwork process among the work process as well as the final visual type. This study is concluded with the summery on the problem and point of consideration when local self-governing organization do visualization work on character business or traditional asset similar to this project.

The matching score evaluating human copying ability can be a good measure to check children's developmental stages, or sports movements like golf swing and dance, etc. It also can be used as HCI for AR, VR applications. This paper presents a method to evaluate the motion similarity between demonstrator who initiates movement and participant who follows the demonstrator action. We present a quantification method of the similarity which utilizes Euclidean L2 distance of Openpose keypoins vector similarity. The proposed method adapts DTW, thus can flexibly cope with the time delayed motions.

The 1900s in New Orleans, the harbor city, was indeed an era of confusion because there were various ethnic groups and races. Songs that had been sung by slaves taken from Africa, Black spiritual music, blues, British folk songs, French folk music, ballet music, Spanish dance music, and the march of military bands were mixed with Rag Time to achieve diversity. This developed the beginning of jazz. While swing jazz was most popular and loved by the public during the 20th century, the bebop preferred the small scale organization of musical instruments and developed as a form of jazz featuring the impromptu musical performances. Later, cool jazz, a new style involving the fast and complicated code progress, emerged with free jazz, which features the fundamental rupture from the tradition of the jazz. Miles Davis, who introduced the rock beat in jazz, started fusion jazz. Although jazz has been named differently depending on the era, the main attraction of jazz lies on improvisation. In other words, despite a small changes in code progress and rhythm, the most important thing the player considers is improvisation. Some famous players who lived in the same era followed the whole atmosphere but each had their own style. So, even when they did play the same song, they revealed their style in solo parts despite the same head.

The purpose of this study was to investigate the relations between the segments of the body, the three dimensional anatomical angle and the angular velocity of the air born phase and understand the control mechanism of the high-bar movement, the somersault, the double somersault, the double somersault with full twist. For this study seven well trained university gymnastic volunteered, Zatsiorky and Seluyanov(1983, 1985)'s sixteen segment system anatomical model was used for this study. For the movement analysis three dimensional cinematographical method(Arial Performance Analysis System : APAS) was used and for the calculation of the kinematic variables a self developed program was used with the LabVIEW 5.1 graphical profromming(Johnson, 1999) program. By using Eular's equations the three dimensional anatomical Cardan angles of the joint and angular velocity were defined. As a result of this study 1. As the rotation of the body increased in the air born phase the projection angle of the CM of the total increased, this resulted the increased of the max hight of the CM. 2. In three dimensional angular velocity the Z axis(vertical direction) projection angular velocity increased as the rotation of the body increased in the airborn phase, but the Y axis and the X axis projection angular velocity did not show significant differences. 3. As the rotation of the body increased in the air born phase the angular movement of the shoulder and the hip showed significant change. These movement act as the starter in the preparation phase. 4. The somersault angle, the twist angle, the tilt angle of the upper body related to the global reference frame in the releas phase the average somersault angle of the three types of high-bar movement was $57.7^{\circ}$, $38.8^{\circ}$, $39.7^{\circ}$, the average tilt angle was $-1.5^{\circ}$, $-5.4^{\circ}$, $-8.4^{\circ}$, the average twist angle was $13.4^{\circ}$, $10.6^{\circ}$, $23.3^{\circ}$. This result showed that the somersault with full twist had the largest movement.
