Abstract: A fringe projection-based spatial phase imaging monitoring system using a single optical path includes: a light source; a first beam splitter that transmits a first light and reflect a second light; a tilt mirror that reflects the first light transmitted through the first beam splitter back toward the first beam splitter and varies a phase of the first light; a mirror that reflects the second light reflected by the first beam splitter back toward the first beam splitter; a lens that condenses the first and second lights reflected by the tilt mirror and the mirror; a second beam splitter that transmits the condensed first and second lights toward a sample and reflects light returning from the sample; and an image sensor that captures an image of the sample in which a fringe is formed according to a phase difference between the first and second lights.

Abstract: The present disclosure relates to a bright- and dark-field microscope for biological tissue analysis. The object of the present disclosure is to provide a bright- and dark-field microscope, which can obtain both bright-field and dark-field images at the same time and, particularly, can be conveniently used for biological tissue analysis. More specifically, the object of the present disclosure is to provide a bright- and dark-field microscope for biological tissue analysis, the microscope having, as a single optical path and a reflective type, an optical system that can acquire bright-field and dark-field images and, particularly, using white light as a light source so as to even smoothly perform conventional H&E analysis in which a biological tissue is analyzed.

Abstract: A tempered glass crushing device including a support unit (110) that is disposed in contact with a surface of a tempered glass to be crushed and has a tip movement hole (111a) formed in a plate surface thereof. The device further includes hitting unit (120) that is vertically movably coupled to an upper portion of the support unit (110) and has a crushing tip (123) for hitting the tempered glass through the tip movement hole (111a) while lowered to a central region. The device further includes a safety pin (140) inserted between the support unit (110) and the hitting unit (120) to prevent the hitting unit (120) from being lowered arbitrarily.

Abstract: Provided is a method of monitoring a heart rate of an open circulatory system aquatic organism including water fleas, zebrafish, brine shrimp, and the method of evaluating individual response by real time measurement of a heart rate of an aquatic organism and the individual response evaluation apparatus by real time measurement of a heart rate of an aquatic organism according to the present invention may effectively fix the aquatic organism for real time measurement of the heart rate of an aquatic organism, and may measure the heart rate using digital holography to display the heart rate while configuring a data format to allow the corresponding data to be stored for a long time, thereby treating a compound for inducing an individual response, securing a heart rate change in real time by image processing, and then effectively determining the presence or absence of harmfulness due to induction of the individual response.

Abstract: A method for intelligent disaster and safety management interworking with artificial intelligence, can include generating, by a detector, a plurality of pieces of detection information. The method can further include transmitting, by a communication part, the plurality of pieces of detection information to a control server. The method can further include receiving, by the communication part, control information from the control server. The method can further include controlling, by a controller, an output part according to whether a fire (or an urgent situation) has occurred on the basis of the control information (on firefighting, crime, and emergency).
