A method for measuring the thickness of a specimen, according to an embodiment, can measure the thickness of a specimen having multiple layers in a contactless and non-destructive manner. In addition, when the refractive indexes of materials forming the respective layers are already known, the thicknesses of the respective layers can be integrally measured through differences in reflection times of terahertz waves with respect to the respective layers of the specimen, thereby measuring the thickness of the specimen, such that the time taken for measuring the thickness of the specimen can be reduced. Furthermore, when the refractive indexes of the materials forming the respective layers are not known, the refractive indexes of the respective layers can be measured through differences in transmission times and reflection times of terahertz waves with respect to the respective layers of the specimen, and at the same time, the thicknesses of the respective layers can be measured through differences in transmission times or reflection times of terahertz waves with respect to the respective layers of the specimen, so that the thickness of various specimens can be measured. As such, the present invention has a wide range of applications.

Disclosed herein is a hybrid ventilation apparatus capable of both natural and forced ventilation. In the case of a natural ventilation mode, a worm gear is rotated in a normal direction by drive force of a drive unit under control of a control unit so that a pressing member engages with a rotation guide protrusion and rotates a damper, thus opening a flow passage, and then the worm gear is reversely rotated by drive force of the drive unit to return the pressing member to its original position, thus allowing a user to rotate a roller upwards and downwards and rotate the damper so that the degree of opening of the flow passage can be adjusted. Thereby, rapid inflow of outdoor air can be blocked, and a cold graft phenomenon, in which the temperature of indoor air rapidly drops, can be prevented.
