빛은 인간과 동물에서 일주 리듬과 신경내분비 활동을 조절하는 자극이다. 망막-시상하부 경로는 주/야 주기와 신경내분비 활동에 관여한다. 특히 멜라토닌 분비는 빛에 의해 영향을 받으며, 다양한 측면의 건강 문제와 관련이 있다는 것이 알려져 왔다. 본 논문은 생물학적 리듬과 신경내분비 활동에 있어서 빛이 수행하는 역할과, 빛과 건강 문제와의 관련성, 망막-시상하부 경로의 특성을 소개하고자 한다.

Five kinds of double stacked 385 (55 x7) filamentary Bi2212/Ag round wires and 55 filamentary tapes with different Ag ratios (silver area/superconductor area) have been fabricated via PIT method, and the effects of Ag ratio and processing factors on critical current density were studied. The effects of the maximum temperature and average filament diameter on critical current density were also studied. The wire of 0.74 mm diameter having Ag ratio 3.7 showed critical current density of at 4.2 K, 0 T.

Magnetic Properties of Amorphous FeSiB and Nanocrystalline Fe73Si16B7Nb3Cu1 Soft Magnetic Sheets

Cho, H.J., Cho, E.K., Song, Y.S., Kwon, S.K., Sohn, K.Y., Park, W.W.

The magnetic inductance of nanocrystalline Fe73Si16B7Nb3Cu1 and an amorphous FeSiB powder sheet has been investigated to identify RFID performance. The powder was mixed with binder and solvent and tape-casted to form films. Results show annealing significantly influenced on the inductance of the material. The surface oxidation of the particles was the main reason for the reduced inductance. The maximum inductance of Fe73Si16B7Nb3Cu1 alloy was about 88μH at 17.4 MHz, about 65% greater compared to the FeSiB alloy. The higher inductance in the nanocrystalline alloy indicates it may be used as a potential replacement of current RFID materials.
