THE ECONOMIC THOUGHT OF J.B.CLARK: AN INTERPRETATION OF fTHE CLARK PROBLEM'

In this paper tour points have been claimed: (1) J.B.Clark's etransformationf was not 'a mere change of emphasis', but a radical change; (2)The early dark as a Christian socialist regarded a co-operative system as an ideal economic system, and it was not necessary to be within the capitalistic framework: (3) The later Clark's etransformation' to the justification of a capitalist competitive system was brought about by the establishment of his specific productivity theory of distribution. The formation process of this theory involves the confusion of an ethical approach and a theoretical approach at three levels: stating a problem, construction of the theory itself, and the social implication of it; (4) The later Clark as an antimonopoly policy propose recognized trusts without monopolistic power as being necessary to harmonize efficiency and justice. His final reformist position was well shown in his Social Justice without Socialism.

Electron transport in a ferromagnet-superconductor junction on graphene

In a usual ferromagnet connected with a superconductor, the exchange potential suppresses the superconducting pairing correlation. We show that this common knowledge does not hold in a ferromagnetsuperconductor junction on a graphene. When the chemical potential of a graphene is close to the conical point of energy dispersion, the exchange potential rather assists the charge transport through a junction interface. The loose-bottomed electric structure causes this unusual effec

Application of rubber artificial muscle manipulator as a rehabilitation robot

The application of a robot to rehabilitation has become a matter of great concern. This paper deals with functional recovery therapy, one important aspect of physical rehabilitation. Single-joint therapy machines have already been achieved. However, for more efficient therapy, multjoint robots are necessary to achieve more realistic motion patterns. This kind of robot must have a high level of safety for humans. A pneumatic actuator may be available for such a robot, because of the compliance of compressed air. A pneumatic rubber artificial muscle manipulator has been applied to construct a therapy robot with two degrees of freedom (DOF). Also, an impedance control strategy is employed to realize various motion modes for the physical therapy modes. Further, for efficient rehabilitation, it is desirable to comprehend the physical condition of the patient. Thus, the mechanical impedance of the human arm is used as an objective evaluation of recovery, and an estimation method is proposed. Experiments show the suitability of the proposed rehabilitation robot system </p
