Abstract: A system and methods for determining and delivering soil composition for preventing allergic diseases. An example method includes providing a computer network which communicates with health sensors and environmental sensors. The method, includes providing environmental sensors in a first geographic region to measure environmental conditions of the first geographic region. The method also includes providing health sensors for a sample human population in the first geographic region to measure health conditions of the sample human population. The method also includes computing a soil model that prevents allergic diseases based on the environmental conditions and the health conditions, and synthesizing artificial soil that replicates the computed soil model.

Abstract: A scar reducing device for stretching skin having a closed wound therein is provided. The device is for reducing scar formation. The device comprises first and second fasteners removably attachable to skin regions located proximate to the wound. The device also comprises an extension mechanism cooperating with said first and second fasteners. The extension mechanism is movable between contracted and extended configurations. When the fasteners are affixed to the skin, the mechanism forces the first and second fasteners away from one another with a predetermined tensile force, stretching the skin proximate to the wound. Use of the device is also provided, along with a method for reducing scarring of a closed wound.
