  • Purpose of study: The purpose of this study is to analyze the origins and texts of the Jewish scriptures, the Mishnah Moed, and to examine them from the perspective of educational theology to suggest practical application methods for Christian education. Research content and method: In order to achieve the purpose of the research, the contents were set as follows. First, for analyzing the origin and text of Mishnah Moed, the historical process until Mishnah Moed was edited was reviewed, and the contents of the text of Mishnah Moed were classified into 2 groups of 12 Masekkot from the viewpoint of the researcher; The first group is the contents Shabbath and Festivals : Shabbat, Pesahim, Yoma, Sukkah, Rosh haShanah, Megillah and the other group is as a rule to keep the festival, Erubin, Sheqalim, Betzah, Taanith, Moed Qatan, Hagigah. Second, in order to analyze the mishnah moed in educational theology, the church calendar for the festivals currently used in Christianity was analyzed by dividing it into the origin of the church year, the contents of the church year, and the scriptures of the church year. Third, as an educational model for applying Mishnah Moed to Christian education, the goal of seasonal education, the content of seasonal education, and the method of seasonal education were presented. Conclusions and Suggestions: The conclusion of the research is as follows; First, seasonal education based on the teachings of the Bible must be conducted within the Christian community. Second, The education is needed for leading a life that correctly understands and practices the historical process of the Christian festivals. Third, various church education programs should be developed and utilized according to the Christian Bible routine. Fourth, numerous symbols symbolizing the Christian festivals must be created and educated. Fifth, except for the festivals of the sufferings of Jesus Christ, the rest of the festivals must be observed as Celebration.

  • A new control algorithm so called equal excursion sliding mode (EESM) control method is proposed to control the position of DC servo motor. This method introduces the concept of phase velocity vector that Filippov presented, and simplifies the problem of control gain selection in a conventional VSC strategy. And, by making state trajectories have equal excursions on both sides of switching hyperplane we minimized the probability of sliding mode's being collapsed, and approximated to the ideal sliding moed. Also, we proved the validity of this method by comparing the application results of this method to DC servo motor with those of conventional VSC strategy.

  • This paper present a new disk-type piezoelectric transformer. The input side of the transformer has a crescent-shaped electrode and the output side has a focused poling direction. The piezoelectric transformers operated in each transformer's resonance vibration mode. The electrodes and poling directions on commercially available piezoelectric ceramic disks were designed so that the planar or shear mode coupling factor ($k_p,\;k_{15}$) becomes effective rather than the transverse mode coupling factor ($k_{31}$).
