  • Objective: The purpose of this study was to investigate the effect of acute transcranial direct current stimulation (tDCS) on the isokinetic muscular endurance of the lower extremity for young adults. Method: Thirteen young adults performed isokinetic fatigue tasks for two experimental conditions including real tDCS and sham stimulation protocols. Before and after the task, the tensiomyography was used for evaluating muscle contraction characteristics of vastus medialis and semitendinosus. Paired t-test was performed to compare the fatigue index, changes in maximum radial displacement (∆Dm), delay time (∆Tc), and velocity of contraction (∆Vc) between tDCS conditions. Results: We found no significant differences in the fatigue index between real and sham conditions. In addition, the analyses identified no significant different values of ∆Dm, ∆Tc, and ∆Vc in the vastus medialis and semitendinosus between real and sham conditions. Conclusion: These findings suggest that the tDCS protocols may have no acute effect on lower limb muscle endurance for young adults. Future studies should consider the long-term effects of repetitive tDCS sessions, various stimulation positions, exercise tasks, and participant characteristics to more clearly understand the effect of tDCS on muscle endurance of lower extremities.

  • Our understanding of dust emission, interaction, and evolution, is evolving. In recent years, electric dipole emission by spinning dust has been suggested to explain the anomalous microwave excess (AME), appearing between 10 and 90 Ghz. The observed frequencies suggest that spinning grains should be on the order of 10nm in size, hinting at polycyclic aromatic hydrocarbon molecules (PAHs). We present data from the AKARI/Infrared Camera (IRC) due to its high sensitivity to the PAH bands. By inspecting the IRC data for a few AME regions, we find a preliminary indication that regions well-fitted by a spinning-dust model have a higher $9{\mu}m$ than $18{\mu}m$ intensity vs. non-spinning-dust regions. Ongoing efforts to improve the analysis by using DustEM and including data from the AKARI Far Infrared Surveyor (FIS), IRAS, and Planck High Frequency Instrument (HFI) are described.

  • Objectives: The role of physician-scientists who bridge the gap between basic science and clinical medicine is crucial in advancing medical innovation. This study aims to examine the educational and research environment and career satisfaction of graduate students in Korean Medicine among those who are Korean medicine doctor (KMD). Methods: This study analyzed the results of a survey consisting of respondents' composition, job status, graduate education and job satisfaction, economic conditions, career determinants, and obstacles to the career path of KMD-scientists from 65 participants including both full-time and part-time graduate students. Results: The results revealed significant differences between full-time and part-time graduate students in terms of weekly hours spent and job priorities, motivation for entering graduate school, career preferences, and desired career paths. The study highlights the need for tailored support for full-time and part-time graduate students and the importance of economic assistance in fostering KM scientists. Economic difficulties were identified as a major obstacle for full-time graduate students pursuing research careers. Tuition fees were found to be a significant burden for all graduate students. Furthermore, it emphasizes the importance of enhancing the research capabilities of part-time graduate students and improving the quality of education to foster KMD-scientists. Conclusion: This research provides essential insights for Korean Medicine colleges and graduate schools to develop targeted improvement plans and effectively train KMD-scientist.
