The metallurgical characteristics of hot metal desiliconization by MnO₂-Fe₂O₃ flux containing CaO-CaF₂ were investigated and the following results were obtained. 1) It was found that the flux had nearly equal effectiveness for desiliconization to Fe₂O₃-CaO-CaF₂ flux and manganese content in the hot metal increased with increasing MnO₂ content in the flux, while with Fe₂O₃,-CaO-CaF₂ flux considerable manganese loss was observed. 2) Decarburization degree was about 10%, dephosphorization degree was between 8-12% based on the flux compositions studied. Desulphurization increased to 15-30% when MnO₂ was added in the flux. 3) Increasing slag basicity enhanced desiliconization and recovery of manganese. 4) The initial rate of desiliconization was thought to be controlled by transfer of silicon in hot metal.

This research aims at comparing and analyzing regional differences of senior gateball players. This study show we get positive and desirable results in the areas of their life conditions, their sports related problems, and their attitude and evaluation of gateball. On the other hand, this study shows little difference between urban and rural areas. In conclusion, it has been shown that some problems were caused by human relationship, but not to a significant extent.

As the number of people enjoying sports increases, it is necessary to begin to open schools' physical training facilities to the public in order to eliminate the imbalance of demand for sports facilities. The reason for the delay in opening the facilities is a matter of responsibility and management accompanied by the opening, and I argue that the Office of Education concerned should take full responsibility. A survey of the city of Gimhae on this matter shows that only a few schools open their facilities to the public, but that an organized and systematic opening has not been realized. As a method for pursuing the business of opening schools' physical training facilities, this paper analyzes what is being done in Japan at present and tries to correct and make up for its weaknesses.

The purpose of this study is to establish values of sport in terms of social phenomenon by essentially examining the concept and meaning of sport. In the point of view of origin, sport is one of special forms which is systematized as the form of game developed from the competitive activities of play. Therefore, sport is represented as the form of the person's original traits through competition and efforts, and the purpose of performance of sport is achieved by the self-achievement. Essentially, sport contains educational factor, self-purpose factor, technical factor, and self expression factor. So, sport can be developed as desirable by considering above factors in balance. However, the rapid changes of modern society may produce undesirably various social tendency and problems. To remove these problems of human society, firstly, sport must be better utilized with higher idea of human being in the level of social life, and Secondly, regarded to pursue true happiness as the origin of experience of values.
