Abstract: A measuring system includes an optical site reference, such as a reference line within a scope used in surveying, and a calibrated reference scale which provides measurements by optical comparison to the optical site reference. The calibrated reference scale includes centimeter sections which in turn include upper and lower stepped sections. The upper and lower stepped sections are symmetrical with respect to one another such that the upper and lower stepped sections can be easily distinguished from one another from significant distance. Each of the steps of each stepped section indicates a specific, corresponding offset within the stepped section. The symmetry of the upper and lower stepped sections is in the relative positions of the long and short reference members.

Abstract: An apparatus for controlling a kimchi storage temperature in a refrigerator such that it is equal to the atmospheric temperature in the winter season. The control apparatus includes a chaos signal pattern storing unit for storing a chaos signal pattern corresponding to an atmospheric temperature variation pattern, and a microprocessor for fetching a chaos signal value previously stored in the chaos signal pattern storing unit and comparing a sensing signal value indicative of a temperature of a kimchi seasoning chamber equipped in the refrigerator with the fetched chaos signal value, and controlling the kimchi seasoning chamber temperature on the basis of the result of the comparison.
