Abstract: The disclosure relates to a computer-implemented method, system, and storage medium for collaborative development of a reagent for detection of the target nucleic acid. According to the disclosure, the method, system, and storage medium automatically match the developer and technology provider suitable for the characteristics of collaborative development in response to a request for collaborative development, thereby increasing the efficiency of collaborative development.

Abstract: This application relates to an electrochromic lens. In one aspect, the lens includes a substrate including a first surface and a second surface opposite to the first surface, a first electrode layer disposed on the first surface of the substrate, and a second electrode layer disposed on the first electrode layer. The lens may also include an electrochromic layer disposed between the first electrode layer and the second electrode layer, and adjusting transmittance of light incident on the second surface of the substrate. The lens may further include a first conductor electrically connected to the first electrode layer, and having higher conductivity than at least one of the first electrode layer or the second electrode layer. The lens may further include a second conductor electrically connected to the second electrode layer, and having higher conductivity than at least one of the first electrode layer or the second electrode layer.

Abstract: The present application relates to an electrochromic device. In one aspect, the electrochromic device includes an electrochromic element including a first electrode, a second electrode, an electrochromic layer, an ion storage layer and the second electrode. The electrochromic device also includes controller configured to change a state of the electrochromic element to change to at least one of a first state having a first transmittance, a second state having a second transmittance, a third state having a third transmittance, or a fourth state having a fourth transmittance by applying power to the electrochromic element. When a first voltage is applied to the electrochromic element in a first state, the electrochromic element becomes the second state, and when the first voltage is applied to the electrochromic element in a fourth state, the electrochromic element becomes the third state.

Abstract: A refrigerator is provided which includes a variable temperature storage formed in the chilling chamber; a heating room formed on a side of the variable temperature storage; a heating device installed in the heating room and configured to generate heat; a first local circulating path in which cool air in the freezing chamber flows into a rear path through the variable temperature storage; an adjusting device configured to adjust a quantity of cool air flowing into/out of the variable temperature storage through the first local circulating path; a second local circulating path in which heated air in the heating room passes the variable temperature storage and flows into the heating room again; and a temperature sensor configured to sense a temperature in the variable temperature storage. Because various ranges of temperature can be maintained in the refrigerator, it is possible to perform optimum-temperature storing according to various kinds of foods.

Abstract: A cool air supplying apparatus of a refrigerator comprises a guide passage formed at a rear wall of a refrigerating chamber and provided with a plurality of discharge ports towards the refrigerating chamber for guiding cool air to a rear side of the refrigerating chamber, and a direction control unit installed at the guide passage for selectively opening and closing the discharge ports in order to control a discharge direction of cool air discharged into the refrigerating chamber.

Abstract: In a refrigerator including a variable temperature storage formed in the chilling chamber so as to have a certain space; a heating room formed on a side of the variable temperature storage; a heating means installed in the heating room in order to generate heat in power supply; a first local circulating path in which cool air in the freezing chamber flows into a rear path through the variable temperature storage; an adjusting means for adjusting a quantity of cool air flowing into/out of the variable temperature storage through the first local circulating path; a second local circulating path in which heated air in the heating room passes the variable temperature storage and flows into the heating room again; and a temperature sensor for sensing a temperature in the variable temperature storage, because various ranges of temperature can be maintained in the refrigerator, it is possible to perform optimum-temperature storing according to kinds of foods, and accordingly various foods can be stored more freshly
