Purpose: We performed a quantitative and qualitative analysis in the Journal of the Korean Society of Traumatology (JKST) by Bibliometrics to know the trends of articles. Methods: We reviewed articles in the JKST retrospectively through 1988 to 2014. Articles were classified into original articles, case reports, review articles, and also it is further classified as topics and the information related to the Department of Medicine of corresponding author. Original article was classified prospective and retrospective studies. Results: 753 studies and average of 27.9 studies per year were posted on JKST. 576 original articles (76.5%) were posted. Retrospective studies around 449 studies (78%) were posted and there were about 35 descript studies and 541 analytic studies. The most common themes were related to abdominal trauma, 144 pieces, 95 pieces following damage to the chest and the 84 pieces of special order of trauma. Emergency department had the highest case whereas general surgery came to the second place. Conclusion: Recently, there has been reduced proportion of original article in JKST. It was not possible to evaluate the Korea Citation index journals due to the fact that it does not correspond to listed register Journal of National Foundation of Korea. There will be the need for the effort to improve the maintenance of the posted article number, as well as the qualitative development of the posted articles. [ J Trauma Inj 2015; 28: 182-189 ]

In this study, numerical study is conducted to suggest wing which reduce the vortex strength generated by the leading aircraft. The wing with 3 holes is suggested, which is named as Raon-hajae. Computational grid is created by using pointwise. ANSYS Fluent is employed with the incompressible assumption and RSM turbulence model. As a result of this study, it is confirmed that decrement of lift coefficient is 2.1% and increment of drag coefficient is 11.8%. Nevertheless penalty of aerodynamic performance, reduction of vortex strength is confirmed up to 63%.
