Abstract: The aim of this survey was to provide background theory based on previous research to elucidate the potential pathway by which medical devices using extremely low-frequency high-voltage electric fields (ELF-HVEF) exert therapeutic effects on the human body, and to increase understanding of the AC high-voltage electrotherapeutic apparatus for consumers and suppliers of the relevant devices. Our review revealed that an ELF field as weak as 1-10 μ V/m can induce diverse alterations of membrane proteins such as transporters and channel proteins, including changes in Ca + + binding to a specific site of the cell surface, changes in …ion (e.g., Ca + + ) influx or efflux, and alterations in the ligand-receptor interaction. These alterations then induce cytoplasmic responses within cells (Ca + + , cAMP, kinases, etc.) that can have impacts on cell growth, differentiation, and other functional properties by promoting the synthesis of macromolecules. Moreover, increased cytoplasmic Ca + + involves calmodulin-dependent signaling and consequent Ca + + /calmodulin-dependent stimulation of nitric oxide synthesis. This event in turn induces the nitric oxide-cGMP-protein kinase G pathway, which may be an essential factor in the observed physiological and therapeutic responses. Show more

Abstract: To minimize exposure dose during lateral spine X-Ray testing and obtain optimal image for diagnosis a water filter was made to measure and evaluate dose distribution. When applying the water filter, as thickness increased exposure dose decreased. When applying 2 cm of water filter, clarity of contrast and boundary was found to be 4.5 ± 0.5 and resolution was found to be 2.00 ± 0.5 Lp/mm which was almost identical image quality compared to not applying water filter which showed clarity of contrast and boundary of 5.0 ± 0.0, and resolution of 2.50 ± 0.0 Lp/mm, …while reducing exposure dose by 55%. This result is expected to have many uses as important basic data to predict exposure dose of patients and to minimize medical exposure dose through applying water filters during lateral spine X-Ray testing.

Abstract: In order to analyze tasks of the death education curriculum for the public, DACUM method was used. A committee for DACUM was gathered and a survey was conducted on professors of health care, humanities and social sciences for an interdisciplinary study. In the survey used to verify the model for death education for the public, a compilation based on difficulty and importance factor shows that the 27 tasks including the psychological changes in terminally ill or suicidal patients, healing of stress, acceptance and understanding of death and suicide prevention were identified as needing to be included in the curriculum. The …data thus concluded will have to be reviewed when they are applied to actual education to revise the education program to make it more appropriate. Show more

Abstract: The purpose of this study is to examine the relationship between the protein supplements intake satisfaction level and repurchase intention of university students majoring in physical education and verify the mediation effects of word-of-mouth intention. To achieve the purpose of this study, 700 university students majoring in physical education from 10 universities in Korea were selected from October 2013 to December 2013 as the target of this study through the cluster random sampling and data of 228 university students who had experience in the intake of protein supplements among them was analyzed. The composite reliability of each factor was in …between 0.869 and 0.958, and the convergent validity and discriminant validity were verified. SPSS 18.0 and Amos 22.0 were utilized as data processing methods and the verification of significance on the medication effects and indirect effects of word-of-mouth intention was carried out using the frequency analysis, correlation analysis, CFA, SEM, and Amos bootstrapping. The result is as follows. The protein supplements intake satisfaction level had a positive effect on the word-of-mouth intention and the word-of-mouth intention had a positive effect on the repurchase intention. Also, it was shown that the word-of-mouth intention played a full mediation role between the intake satisfaction level and the repurchase intention. Show more

Abstract: We investigated the burdock extract on the inhibitions of NO generation, COX-2 expression, and the generations of IL-6 and TNF-α , to find out its anti-inflammatory effect in this study. After the treatment of the burdock extract in the cells, we measured the amount of NO generated in the inflammatory cells developed by LPS and UVB, and confirmed the developments of inflammatory mediators by RT-PCR. Upon the results on the NO generation after the development of inflammation by LPS in Raw 264.7 cell, we found approximately 50% of inhibitory effect at 200 μg/ml concentrations of the burdock extract. It was …confirmed that the expression levels of TNF-α, COX-2, and IL-6 were declined to the levels of control by LPS and UVB stimulated inflammation in HaCat cell. This means the anti-inflammatory effect of the burdock extract. Show more
