근대 Olympism의 역사적 변천과정에 관한 연구

한태준,황옥철 慶星大學校 1996 論文集 Vol.17 No.2

To examine the process of historical changes of Olympism, by reviewing and analyzing all sorts of reasons at each of six stages divided according to the changes of the times of the Modern Olympic Games, the object of this study is to set the theoretic foundation necessary for establishing new direction-setting and philosophy of future Olympism. Then, the facts that have been examined so far are summarized as follows. Firstly, the Olympism, which boils down to ties among countries, peace and amateurism, has entered upon complicated and delicate phase, and it has developed into undisguised political intervention, a phenomenon of commercialism and increasing professionalism of sports. Secondly, the number of countries participating in the Olympic Games has mounted to 172 countries in the Barcelona Olympic Games while there were only thirteen countries when the Olympic Games had revived. As the result, the size of the Games has remarkably expanded. In addition, the doping problem, which has emerged as a new issue, is getting more serious. Thirdly, by provoking struggle among nations, the theory of putting victory first linked with national power, is discoloring the noble ideal of the Olympic and its fundamental spirit. In conclusion, to settle these problems, the philosophy of Olympism appropriate for the situation of the times should be established. Besides, the Olympism, based on Pierre de Coubertin's educational philosophy, should be well understood to every nation of the world. Then, the Olympiad will be the best medium for international understanding. Therefore, by being well aware of the fact that the Olympic Games are not competitions among countries but competitions among individuals and competitions with persoanl records, and understanding the philosophy and idea of Olympism, the Olymic Games should regain and develop its pure Olympic spirit.
