  • Purpose: The purpose of this study is to compare the flexibility of high school baseball players’ LBP Group and bilateral lower extremity muscles. Method: This study conducted a questionnaire survey and measurement of muscle flexibility targeting 23 high school baseball players in Korea. The questionnaire consisted of 7 items on basic information and 4 items on past and present back pain, and muscle flexibility measurement (Tomas test, Hip extension, HBD, SLR, Trunk rotation) tests were conducted. As for the data processing of this study, the mean and standard deviation of all questions were calculated by using the SPSS 26.0 package. The two-way ANOVA was performed to examine the effect of each measurement according to the LBP Group (LBP; presence or absence) × both sides (dominant, non-dominant), and if an interaction was found, the post hoc test was conducted. The independent sample t-test and paired t-test were performed for the post hoc verification. The statistical significance level was based on p<.05. Results: As a result of the Thomas test conducted for the LBP Group and both sides of the lower extremity muscle flexibility, the both sides of the main effect turned out to be significant [F(1,21)=4.905, p<.05]. In the case of the hip extension, the main effect of both sides turned out to be significant [F(1,21)=6.768, p<.05], and the main effect of the LBP Group also turned out to be significant [F[(1,21)=5.065, p<.05]. Furthermore, in the case of the SLR, the main effect of the LBP Group turned out to be significant [F(1,21)=5.395, p<.05]. Conclusion: Gathering the results above, as a cause of the LBP among the high school baseball players, there is a possibility that a decrease in flexibility due to hip flexion and extensor tension may be induced, and hence, the possibility of inducing LBP was confirmed due to the excessive use of the back muscles of the accelerator during the pitching and hitting sections. In the future studies, it is necessary to develop and apply the programs which can prevent and rehabilitate the LBP.

Method: In this study, a quantitative study via a questionnaire was conducted for men and women aged 20 years or older residing in area K. In a survey conducted for 500 residents in the nuclear power plant area, a sample of 456 (91.2%) people was extracted, and the results of the survey were analyzed by using the PASW18.0 and the AMOS 18.0 statistical programs, while the hypothesis was tested at the level of statistical significance at p<.05. Results: As a result of the correlation analysis performed, the relationship between the constructs turned out to be a positive (+) correlation, and hence, the direction of the relationship between the variables presented by the research model and the research hypothesis was consistent, while the significance level also satisfied p<.05. As a result of the fit of assessment performed for the research model, IFI=.979, FMIN=.229, NFI=.973, RMSEA=.076, TLI=.986, and CFI=.979 were demonstrated. The overall fit index demonstrated in the research model was χ2(41)=104.032, p<.000. Hypothesis 1 was dismissed as the relationship between the sports cultural marketing and the acceptance of nuclear power generation of Hypothesis 1 (Estimate=.005, C.R.=.080) had no significant effect at the level of significance p<.05. Furthermore, the relationship between the sports cultural marketing and the corporate image of Hypothesis 2 (Estimate=.652, C.R.=14.299) turned out to have a significant influence at the level of significance p<.001, and hence, Hypothesis 2 was adopted. Hypothesis 3 was adopted since the relationship between the corporate image and the acceptance of nuclear power generation (Estimate=.541, C.R.=8.865) of Hypothesis 3 turned out to have a significant effect at the level of significance p<.001. Conclusion: Gathering the results above, first, the KHNP's sports cultural marketing activities did not directly influence the acceptance of nuclear power generation as a matter of causal variable. Second, the KHNP's sports cultural marketing ought to be utilized as a means for increasing the acceptance of nuclear power generation by local residents through the zero high corporate image while acting as a major activity to enhance the corporate image. Accordingly, it is evident that the sentiment induced by the KHNP's sports cultural marketing activities will operate as an important tool in shaping the general local residents' reaction towards the KHNP.
