  • Purpose: The purpose of this study was to determine the effects of the swissball exercise in combination with core muscle in beginner golfer. In general, the swiss ball exercise was related in the core muscle ability. Methods: The experiment was conducted with a total of 10 beginner golfer, and they were dicide into two groups: comparison group(n=5) and experimental group(n=5). In this research, the subjects of the comparison group performed the general matte exercise three times a week, for four weeks. The subjects of the experimental group performed the swiss ball exercise in combination with core muscle three times a week, for four weeks. Use the 7-iron and driver were measured head speed and distance of the comparison group and the experimental group, respectively. The collected data were analyzed by using the paired t-test and ANCOVA Results: The results of this study were as follows: 1) Swiss ball exercise in combination with core muscle revealed the significant improvements after corresponding exercise in golf performance capability. 2) Mat exercise was seen less better than the swiss ball exercises. Conclusion: This results suggested that it was improved the golfer shot performance of beginner proposes to see the Swiss combined movement.

  • The purpose of this study is to review the taxonomic position of Taxus cuspidata var. latifolia endemic to Ulleung Island with related taxa T. cuspidata var. cuspidata, T. caespitosa, and T. cuspidata var. nana based on external morphological characters and DNA barcoding study. T. cuspidata var. latifolia was similar to T. cuspidata var. cuspidata in the arbor, straight trunk, and symmetric arrangement of leaf. But the unique differences between T. cuspidata var. latifolia and T. cuspidata var. cuspidata were leaf size and the exposure of seed from aril. Additionally, sequences of four chloroplast DNA regions including matK, rbcL, trnL intron and trnL-trnF spacer regions were analyzed. Korean Taxus species and their related taxon T. cuspidata var. nana were strongly supported as a monophyletic group in neighbor-joining analysis. Taxus cuspidata var. latifolia showed 100% sequence identity to related taxa. Korean endemic T. caespitosa is also distinguishable from related taxa by prostrate stems and spiral arrangement of leaf. The examinations of external morphology and DNA barcoding study suggest that the taxonomic position of T. cuspidata var. latifolia should be maintained as a variety of T. cuspidata.

  • Purpose : The Purpose of this study was to compare muscle activation and foot pressure on baby carrier and sling for baby care. Methods : Thirty one women subjects (mean age 23.2 years) participated in four static conditions : unloaded quite standing, carrying an anterior baby carrier, carrying a posterior baby carrier, and sling. The baby carrier and sling were loaded with baby model that filled 7.6kg loads. Surface electromyography was used to measure activity in the internal oblique, T4, L3, L5 paraspinal muscle, vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius for four conditions. And foot pressure was measured by using MatScan system(Tekscan, USA). Results : The activation of Biceps femoris, T4, L3, and L5 paraspinal muscle were significant differences(p<.05), but other muscles were no significant differences in four conditions(p>.05). Right foot contact area and peak pressure of right mid foot area were significant differences in four conditions(p<.05). Conclusion : The results of this study indicate that the use of baby carrier of sling for baby care were influenced postural responses of young women. Further work is recommended to find out the influences of various assistive devices for baby care.
