Abstract: A cooking utensil having a thermochromic layer including a thermochromic pigment for a temperature sensor, includes: a metal substrate; a primer layer including a fluorine-based resin formed on at least a part of a surface of the metal substrate; a thermochromic layer including a thermochromic pigment formed on at least a part of a surface of the primer layer; and a top coating layer including a curing agent formed on surfaces of the primer layer and the thermochromic layer. The thermochromic pigment is a thermochromic pigment for a temperature sensor using bismuth vanadate.

Abstract: Provided are a test method and apparatus for evaluating cognitive function decline. The test method for evaluating cognitive function decline includes performing a testing stage of testing how many missions presented for each of a plurality of test items a user performs, and calculating a test score for each of the plurality of test items, performing a category classifying stage of classifying at least one test item from among the plurality of test items as one neurocognitive category from among a plurality of neurocognitive categories, and performing an evaluating stage of evaluating whether there is cognitive function decline in the one neurocognitive category, based on a test score of the at least one test item classified as the one neurocognitive category.
