The purposes of this study are to examine the problems and improvements of the current recreational baseball leagues and propose a measure to vitalize the recreational baseball leagues through delphi technique in order to propose an integrated measure by collecting the opinions of experts. Delphi survey was conducted for a total of 4 times. In regard to the collected results, the factors were categorized through the expert meeting. As a result, 4 final meta-factors and 20 sub-factors were derived. As a result of the final delphi survey, ‘expansion of relevant management departments for recreational baseball leagues’ and ‘mitigation of permit system for baseball facility’ were found to have the highest degree of potential for change in relation to the administrative system. As for hope scale, ‘expansion of relevant management departments for recreational baseball leagues’ was found to have the highest degree. In regard to organization, ‘improvement of the problem associated with league operation and political adhesion relationship’ was found to have the highest degree of potential for change. As for hope scale, ‘integration of different local rules of each league’ was found to have the highest degree. In regard to facility and supplies, ‘new construction of baseball park in each region’ was found to have the highest degree of potential for change. As for hope scale, ‘distribution of diverse supplies and equipment’ was found to have the highest degree. Lastly, in regard to infrastructure, ‘securing budget through corporate sponsorship’ was found to have the highest degree of potential for change. As for hope scale, ‘promotion of recreational baseball leagues in local communities’ were found to have the highest degree.

Prunus serrulata var. serrulata f. spontanea (E. H. Wilson) C. S. Chang was treated with dried swine excrement at various concentration levels, and their growth reactions and the contents of total kjeldahl nitrogen and total phosphoric acid were analyzed. The result is as follows; 1. When the plants were treated with 0.25% of dried swine excrement, the seed germination rate of Prunus serrulata var. serrulata f. spontanea was higher than that of the control. However, it showed a tendency to decrease when the treatment concentration got higher than 0.25%. 2. The growth rate of species was highest when they were treated with 0.25% of dried swine excrement. It tended to decrease with higher treatment concentration than 0.25%. Significant difference was clear between the control and the experimental plants of Prunus serrulata var. serrulata f. spontanea. 3. The contents of nitrogen and phosphoric acid in Prunus serrulata var. serrulata f. spontanea also got higher as the concentration of dried swine excrement increased. However, the content of total kjeldahl nitrogen was highest in the leaves, and followed by the roots and stems. In contrast, the content of total phosphoric acid were highest in the roots, and followed by the leaves and stems. Therefore, stems had the lowest contents of both nitrogen and phosphoric acid. 4. The contents of total kjeldahl nitrogen and total phosphoric acid in the soil were measured before and after the growth experiment of Prunus serrulata var. serrulata f. spontanea treated with dried swine excrement. The contents of nitrogen and phosphoric acid significantly decreased after the experiment. In conclusion, the contents of total kjeldahl nitrogen and total phosphoric acid accumulated in the plants increased as the concentration level of dried swine excrement got higher. The seed germination and plant growth rates were best at 0.25% treatment of dried swine excrement. The treatment of dried swine excrement may bring high effects on increasing the plant growth rate but could damage the plants with higher concentration than they need. Different optimal concentration levels of dried swine excrement for different plants should be found before it is used as fertilizer.
