Provided is a device for measuring an amount of perspiration of respective body parts of a person using a change in brightness, including: a temperature controller which raises temperature of a subject and induces sweating; a covering which is coated with a perspiration reagent and is in contact with a skin of the subject, wherein the perspiration reagent absorbs perspiration and changes its color in response to perspiration; a light irradiator which irradiates light to the covering; a reflected light collector which collects reflected light reflected from the covering; a brightness change measurer which measures a change in brightness of the reflected light collected by the reflected light collector; and a perspiration amount converter which converts the change in brightness to an amount of perspiration secreted from respective body parts of the subject.

Device for measuring amount of perspiration with regard to each part of human body by using change in brightness and method for measuring amount of perspiration

Provided is a metal-resin complex in which a metal alloy and a resin composition that are heterogeneous materials are integrated with each other, and more particularly, a method for producing a metal-resin complex capable of improving bonding strength by producing a metal alloy having a more uniform etching surface using an alkaline aqueous solution to which a chelating agent is added and an acid aqueous solution to which the chelating agent and an amic acid are added, and injection-molding the resin composition by using the produced metal alloy.

Provided is a method of preparing an aluminum-resin complex in which an aluminum alloy and a resin composition are integrated with each other. More particularly, the present invention is relates to a method of preparing an aluminum-resin complex having improved bonding strength by preparing an aluminum alloy having a more uniform etching surface using an alkaline aqueous solution to which a chelating agent and a cycloamine are added and an acidic aqueous solution to which a chelating agent is added and injection-molding a resin composition using the aluminum alloy.

A method of measuring the height of a foot arch precisely and easily using two essential heights of the foot arch is disclosed. In the method, a foot cast is primarily cast by pouring plaster into a foot mold. Thereafter, a first intersecting point and a second intersecting point are determined. The first intersecting point is determined by making a first line and a third line intersect. The second intersecting point is determined by making a second line and the third line intersect. The first line is a straight line extending from the center of the second toe to the center of the heel end. The second line is a straight line extending from the center of the big toe to a point spaced apart inwardly from the center of the heel end by &frac18; of the total distance of the heel end. The third line is a center line of the transverse arch of the foot. Finally, a first height and a second height are measured while the foot pattern is set in an upright position. The first height is defined between a flat base level and the first intersecting point, while the second height is defined between the base level and the second intersecting point.
