The purpose of this study was to investigate the effects of LED and QD-LED (Quantum Dot) irradiation on seed germination, antioxidant ability, and microbial growth, during red radish (Raphanus sativus L.) sprouts cultivation. Irradiated light was blue, red, blue + red and blue + red + far red (QD-LED) lights, and the controls were a fluorescent lamp (FL), and dark condition. Germination rate of red radish was highest in the dark condition. The plant height and fresh weight of red radish sprouts that irradiated each light for 24 hrs after 7 days growing in dark condition, did not shown significantly difference among treatments. After 24 hrs of light irradiation, cotyledon green was best in blue + red light, and the red hypocotyl was excellent in blue light and QD-LED light. DPPH and phenol contents were high in dark and blue + red light treatment, and anthocyanin content was high in blue light and QDLED light. Total aerobic counts were similar in all treatments and did not show bactericidal effect, whereas E. coli count was lowest in QD-LED light treatment, and yeast and mold counts were lowest in FL only treatment. Results suggest that when red radish seeds were germinated in dark condition and cultivated for 7 days as sprouts, and then treated with blue light or QD-LED light for 24 hrs, the seeds produced good quality red radish sprouts with greenish cotyledon, reddish hypocotyl, high anthocyanin content, and lower level of E coli contamination.

There are exits bibliographically interrelations among Meridian-Qi, electricity and magnetism. However, it is difficult to provide one dimensional reductionism such a thought that nervous system is meridian system and their function is involved directly to Meridian-Qi, because many unkwon factors are conducted to the function of organism. Furthermore, it's in need of a detail study to understand the characteristics of common feature and difference among Meridian-Qi, electricity and magnetism in the organism.

Many publications of pointology have been conflicted to define fixed positions of acu-points. These underlying cause results from the historical fact that most of acu-points and meridian systems began at anonymous experiences of many generations. However, if we would believe that the acupoints and meridian systems exit clearly in all of the organism, there were exit the fixed position of acupoints. In this study, we performed bibliographically the investigation fixing the position of CV16. From the investigation, although supported that it exit 1.6 chon (寸) below CV17 in human being, we suggest that CV16 exit below the sternum met with the 7th rib, or the joined point between the sternum and the xiphoid process.
