It was Olympia's games which represented the ancient Greek civilization for a millenium from 776 BC until 395 AD. Athletes were respected by the public, and it was believed that the body and mind of man were inherited from God and that training was the finest way to worship God. The ancient Olympic games were mainly consisted of 200m running, 400m, 4800m, pentathlon, wrestling, boxing, pancration, and horse chariot race, which were adopted as official events to compete with the physical strength and skills required for war or combat. The martial art games continued as a means of survival and a way of physical training. The modern Olympic games have been held every 4 years since 1896, and the Olympic games are currently consisted of approximately 400 events for 52 events across 33 areas. For the summer Olympic games, there are some games such as track and field, swimming, fencing, and gymnastics which are maintained as official events from the first game, and there are also the ones which were piloted initially then approved as official events thereafter. Or, there are the ones which were formal events, yet excluded from official events on certain occasions. IOC has established the Olympic Programme Commission and has set 7 standards to enable meeting of the history, tradition, universality, popularity and potential, athlete's health, sports management ability, and sports management costs in order to be more systematic in approaching Olympic games, adjusting Olympic games. In particular, when the modern Olympic games began as martial art games in which result was determined either directly by striking the human body or by overtaking, there are wrestling and boxing, which were adopted as Olympic events, Judo, which was adopted as a formal event at the 18th Tokyo Olympics in 1964, Taekwondo, which was adopted as a pilot event during the 1988 Olympic Games in Seoul and as a formal event at Sydney in 2000, and Karate, which was adopted as a formal event at the Tokyo Olympics in 2020. As such, while martial art games are observing the standards of the Olympic Programme Commission, yet the IOC has allowed the Olympic host cities to decide additional events through the 'Olympic Agenda 2020' thereby increasing their number, and through the Olympic games, host countries are striving to improve their national interests, international stature, and their pride, rather than promoting the understanding of international peace and harmony. Therefore, this study will be helpful for understanding the impact of the martial art games on the Olympic spirit as a sports development and martial arts, and the trends in sports diplomacy through the Olympic games as per the standards of the 'Olympic Programme Commission.'

The spine is a column of our body and dissymmetry of the spine can cause problems on our health. In this study, the origin of idiopathic spine dissymmetry among adolescents is explained that physical force does not flow fully so that chilly draft comes into being. The main purpose of this study is to analyze the effect of the spine dissymmetry improvement program. X-ray examination on the thoracic vertebrae and the lumbar vertebrae was applied before and after 12-week Dahn Taekwondo program to each participant. In this study, we apply the Dahn-Taekwondo 'Spinal Asymmetry Improvement Program' to 18(9-18 year old) adolescents with spinal asymmetry 3 times per week and 1 hour per 1 day for 12 weeks. The results are as follows. First, the Dahn-Taekwondo spinal asymmetry improvement program brings significant reduction(p <.001) of the Cobb's angle of thoracic asymmetry in adolescents. Second, in the Taekwondo lumbar asymmetry improvement program, the lumbar asymmetry Cobb's angle of adolescents decreased significantly(p <.001). These findings indicate that the Dahn Taekwondo spine improvement program is effective for the juveniles with spine dissymmetry and can be recommended to prevent and treat spine dissymmetry among juveniles. Therefore, Dahn-Taekwondo spinal asymmetry improvement program can be used as a body correcting exercise for young people who do little physical activity and especially sit long time with unstable postures.

The purpose of this study is to provide and utilize basic data to maximize enhancement of Judo performance as a basic data for developing anxiety resolution training program for maintaining optimal state of psychology in order to analyze the differences in the state of sporting confidence according to the extent of physical training of high school Judo athletes. Therefore, the results of this study are as follows. It was to analyze and identify the relationship with the influence of the extent of physical training of the high school Judo athletes on the state of sporting confidence. In addition, when applying such results to the improvement of performance, it was to accurately identify the level of each individual's extent of physical training to control the achievement motive, resolve the anxiety of the state of competition and sporting confidence of high school Judo athletes, while simultaneously presenting to enable appropriate management and guidance. In the state of sporting confidence, the extent of physical training did not demonstrate any statistically significant difference. That is, there was no anxiety related difference in the state of sporting confidence according to the extent of physical training. Furthermore, the extent of physical training turned out to have no effect on the anxiety of the state of competition(state of confidence). That is, there was no factor influencing the state of sporting confidence.
