This study examined the effects of physical activities using Korean dance upon the motor abilities of young children. The subjects of this study were divided into 2 groups. The first group was an experimental group (boy=12, girl=13) who participated in the Korean dance class and the other group was a comparative group (boy=11, girl=14). Experiments were performed during 18 sessions for 9 weeks. The study findings are as follows. First, physical activities using Korean dance had positive effects upon the development of basic motor abilities in young children. In terms of these basic motor abilities, movement motor ability and whole muscle operation motor ability showed significant differences between the pre-test and post-test stage in the experiment group and between the experimental and comparative groups in the post-test stage. On the other hand, in terms of non-movement motor abilities, there was a significant difference between the pre- and post-test stages for the experimental group, but no significant difference in the post-test stage for the experimental or comparative groups. Second, physical activities using Korean dance had positive effects upon the development of perceptive motor abilities in young children. In other words, in the sub-variables of perceptive motor abilities, there were significant differences between the pre- and post-test stages of the experimental group which experienced physical activities using Korean dance. In conclusion, the study findings showed that physical activities using Korean dance had positive effects upon the increase of both basic motor abilities and perceptive motor abilities in young children. Additionally, the experimental group exhibited more positive effects in the various areas of motor abilities than the comparative group.

Objectives The purpose of this study was to investigate the effect of Hyulboochucke-tang on the collagenase induced intracerebral hemorrhage in white rats. Methods To identify the effect of the Hyulboochucke-tang on intracerebral hemorrhage, intracerebral hemorrhage was induced in the right caudate nuclei of white rats. For normal group (n=12) and comparative group (n=12), saline was dosed, and vaccum evaporated Hyulboochucke-tang extract was dosed to treatment group (n=12), 3 and 10 days after the collagenase injection, the body weight, the brain weight, the size of hematoma, the size of the area of malacia, the number of apoptotic cell and the change in pathological histology were observed. Results 3 days after the injection, the brain weight(g) was considerably decreased in treatment group (n=12) compared to comparative group (n=12). The brain weight after 10 days of the injection was also considerably decreased in treatment group (n=6) against comparative group (n=6). The cross section(mm) of cerebral malacia after 10 days of the injection was considerably decreased in treatment group (n=6) compared to comparative group (n=6). The number of apoptotic cell in normal intracerebral around the area of malacia did not show considerable change between treatment group and comparative group. 12 days after the injection, the multiplication of gitter cells, astrocyte and newly formed capillaries around the area of malacia was distinct. Conclusions On the basis of these results, We sugggest that Hyulboochucke-tang controls swelling caused by hemorrhage and contributes to absorption of hematoma by multiplication of newly formed capillaries and recovery of damaged cerebral tissue by multiplication of gitter cells and astrocyte.

The purposes of this study investigated the effects of placement of analogy on the conceptual changes of air of elementary students, while learning the air conceptions. The subjects consisted of 108 students who are in the sixth grade classes in an elementary school in Busan city. For this study, comparative group(37 members), experimental group I(37 members), and experimental group II(34 memgers) were selected. A pre-test and a post-test on the air conception were done both for the comparative group and the experimental groups. The results are as follows. First, the averages of experiment group I and II are statistically higher than comparative group's. By the way, it just has a small gap between the comparative group and the experimental II. In other words, activity of analogy does not keep always constant to change of air conceptions of elementary students. Therefore, it has a different reason that only before or after during the analogy. Second, it shows that experimental group I has effected on a more change of air conceptions as compared with experimental group II. Then, the first group's result shows better than the other group's result. From this result, six grade students showed a change of air conceptions very well by analogy. It means if the analogy is given to students at the beginning state of chapter, they can understand scientific concepts easily.
