Abstract: A magnetic field effect transistor is presented. A magnetic field effect transistor comprises a current control part and a magnetic field applying part. A current control part comprises multiple electrodes and a current flowing material region located between multiple electrodes and in which the amount of current flowing between the electrodes is changed, and a magnetic field applying part applying a magnetic field generating from a magnetization state, which changes according to external input, of a pre-set material. By controlling current by using magnetic fields, high speed operation is possible as charging time is not required, and calculation results may be stored without external power supply because magnetic field is supplied by altering magnetization state of a material according to external input.

Abstract: The present invention relates to a composition of a hair growth facilitator comprising camphor extract, morus bark root extract, new shoot extract of a pine tree, and fibrous biopolymer produced by silkworm cocoons. By having a superior hair growth effect without any known side effects or toxicities, the present invention can resolve the drawbacks present in the conventional compositions of hair growth facilitators and thus can be safely applied to various hair-related products such as hair tonic, hair lotion, hair cream, hair shampoo and hair conditioner.
