Cyclohexane에 녹아있는 Triton X-100/n-hexanol/water 계의 비이온성 역미셀(reverse micelle)에 대한 미세 환경정보를 알아보기 위해 methylene blue(MB)를 이용하여 흡광 및 형광 분광법으로 고찰하였다. 역미셀의 극성 중심(polar core)에서 물의 미세 상태에 대한 정보는 MB와 Triton X-100 사이의 착물형성과 용매화변색(solvatochromic)거동을 조사해 봄으로써 얻을 수 있었으며, 역미셀의 안쪽 극성 중심에서 3가지 상태로 존재함을 알 수 있었다. 물의 세 가지 상태에 대한 $W(=[H_2O]/[Surf])$값은 0.71, 4.98, 7.26으로 측정되었으며, 그에 대한 MB의 형광수명은 $15.45 ns{\pm}0.56$, $12.27 ns{\pm}0.79$, 그리고 $8.28 ns{\pm}0.82$으로 나타났다. In order to find out the microscopic environmental information on the nonionic reverse micelle of Triton X-100/n-hexanol/water in cyclohexane, an absorption and fluorescence spectroscopic study has been conducted using a methylene blue(MB). The information on the microscopic states of water in the polar core of the reverse micelle has been found by investigating complex formation and solvatochromic behavior between MB and Triton X-100. As a result, it was found that there exist three states in the polar core of the reverse micelle. The measured values of $W(=[H_2O]/[Surf])$ for the three states of water are 0.71, 4.98, and 7.26, and the corresponding lifetimes of MB are $15.45 ns{\pm}0.56$, $12.27 ns{\pm}0.79$, and $8.28 ns{\pm}0.82$, respectively.

Targeting 4 physically healthy men, this study was aimed to analyze kinematic variable and those of wearing led by airbag of their shoes when they walk and step down through ground reaction forces and muscle converter. For a measuring method, right lower legs were set as a standard. After lateral great muscle, rectus femoris muscle, midvastus, anterior tibial muscle, bicephalus femoris, semitendinous muscle, gastrocnemius medialis and lateral gastrocnemius were set as places to measure electromyogram analysis of walking and stepping down as well as ground reaction forces at the same time, the conclusion was deducted as follows. 1. No statistically significant difference was not revealed by change of ground reaction forces from all walking subjects before and after wearing led by airbag. 2. Some statistically significant difference was disclosed by vertical ground reaction forces from all stepping down subjects before and after wearing led by airbag. 3. Some statistically significant difference was revealed by lateral great muscle from all walking subjects before and after wearing led by airbag. 4. Some statistically significant difference was revealed by anterior tibial muscle from all stepping down subjects before and after wearing led by airbag. However, the results showed the decrease of individual muscular activity and the change of ground reaction forces as some statistically significant difference was revealed partially from ground reaction forces and muscular activity. This suggested that wearing led by airbag for a long time could decrease muscle fatigue and stabilize ankles from impact against ground and that it could be expected to provide a method to prevent muscular skeletal diseases of people standing for a long time work.

Out of Bounds(O.B) 지역 구분이 프로골퍼의 드라이버 비거리와 심리적 불안 정도에 미치는 영향

박범영(Park, Bum-Young),김태완(Kim, Tae-Wan) 한국체육과학회 2019 한국체육과학회지 Vol.28 No.5

This study has been conducted with six male or female professional golfers enrolled in “H” university to identify the differences in the psychological anxiety that accompanies the club speed, ball speed, and the carry which are generated in swings as distinguished by O.B. The measurement used Track-man Pro, a golf ball carry measuring device, to get at the kinematic results, and the anxiety measurement came up with the results below by citing with modifications the anxiety measurement sheet as revised by Kim Jong-in (2014). 1. The in-group variation according to the ball speed change did not register any statistically significant difference among all the subjects except subject “D”. 2. The in-group variation according to the club speed change did not register any statistically significant difference among all the subjects except subjects “B” and “D”. 3. The in-group variation according to the ball carry change did not register any statistically significant difference among all the subjects except subject “B”. 4. As the variables involving the groups, club speed and ball speed registered a statistically significant difference but failed to establish correlation with the ball carry by a driver. 5. The anxiety test showed that the subjects registered anxiety, achievement, and muscle tension with respect to the perception of O.B. and that they were reduced to limited swing. The conclusion suggests that the swing as limited by their visual anxiety is universal among the golf players. Especially, the correlation with ball carry can show that the actual athletic ability is influenced by the golfers’ psychological confidence and the biomechanic factors. Therefore, it is believed that research on the cooperation between sports psychology and biomechanics is very useful in providing scientific support to existing studies. Therefore, a follow-up study will have to be conducted on the correlation between the neurological causes involved in psychological changes and the biomechanics.
