국문초록누락 The purpose of present research is to offer the survey data on the expertise, the understanding of children's physical development and their physical activities, and the educational condition, of the instructors who teach physical education (PE) to young children in various educational institutions and other child-related facilities. 207 subjects of survey in a written form performed in this research include instructors belonging to 15 specialized institutions for teaching PE for young children located in Seoul and in Gyeonggi-do. 16 subjects of survey in an oral form (i.e., interviews) include 15 chiefs managing the specialized institutions for teaching PE for young children located in Seoul and Gyeonggi-do. The findings in this research are as follows: First, inspecting the 'expertise' of the instructors who teach PE to young children reveals that majority of the surveyed instructors majored in PE in institutions for higher education; only the half of the surveyed instructors have the qualifying license. Second, the survey on the understanding of children's physical development and their physical activities reveals that the surveyed instructors are well aware of activity progression with respect to children's physical development and teach appropriate physical activities accordingly. Third, the survey on educational conditions reveals that instructional curricula consist mainly of the area in self-testing through employing integrated apparatus while children prefer various games, It is also shown that the surveyed instructors teach proper basis physical activities with respect to children's physical development - easy to difficult activities according to children's age, and that the instructors' preferred apparatuses are mat and uni-bars for children's age 3, 4 and 5.

This study was conducted to investigate angiogenic inhibitory effect of Zingiberis Rhizoma methanol extract using ECV-304 cells and HT1080 fibrosarcoma cells. The viability of ECV-304 was 30% at 50${\mu}g/m{\ell}$ of Zingiberis extract and that of HT1080 was 30% at 100${\mu}g/m{\ell}$. Using the BrdU incorporation assay, Zingiberis inhibited the DNA synthesis of ECV-304 and HT1080 by 70% and 50 % at 200${\mu}g/m{\ell}$. In tube formation assay, at 10${\mu}g/m{\ell}$ of Zingiberis, tube network began to degrade and at higher doses, it was completely destroyed. Zymography demonstrated that Zingiberis extract decreased MMP-9 at 10${\mu}g/m{\ell}$ and higher doses remarkably inhibited the expression of MMP-9. These data indicate that Zingiberis Rhizoma has angiogenic inhibitory effects and shows the possibility of future anti-metastatic drug.
