Abstract: Disclosed are shoes including a body having a foot insertion space into which user's foot is inserted, an air passage portion protruding from a front of the body to the outside and extending in a direction in which the body extends, and a foot support portion located in a width direction of the air passage portion.

Abstract: The present disclosure relates to a fiber for manufacturing a stretchable hydrophobic fiber article, the fiber including silica nanoparticles which are surface-modified such that the silica nanoparticles include a hydrocarbon chain, and a styrene-based thermoplastic elastomer, a stretchable hydrophobic fiber article manufactured therefrom, and a manufacturing method thereof. A fiber and a fiber article according to the present disclosure may have high hydrophobicity, preferably both superhydrophobicity and elasticity. Further, as the fiber and fiber article have excellent mechanical stability and chemical durability, the fiber and fiber article may stably exhibit the aforementioned high hydrophobicity and elasticity even under the harsh conditions.

Abstract: The present disclosure provides a battery pack including a battery cell array in which a plurality of battery cells are arranged in a state in which side surfaces thereof face each other, a heater disposed between the battery cells, a battery management system (BMS) configured to control an operation of the battery cells, and a temperature sensor configured to measure a temperature of the battery cells to transmit the measured temperature to the BMS. Here, when the temperature of the battery cells, which is measured from the temperature sensor, is equal to or less than a critical temperature, the BMS provides a current to the heater to increase the temperature of the battery cells.

Abstract: A bio marker detection device and a method for detecting or generating a bio marker from a plurality of strip sensors are provided. The bio marker detection device includes a close-up lens for detecting an image for the plurality of strip sensors, a transparent frame surrounding the close-up lens to evenly pass light from an outside to the plurality of strip sensors, and a strip sensor holder inlet configured for combining the plurality of strip sensors with the bio marker detection device. The method includes detecting a plurality of bio markers from a plurality of sensors, generating user health information based on the detected plurality of detected bio markers, and displaying the generated user health information.

Abstract: A simple and versatile coaxial turbulent jet mixer can synthesize a range of nanoparticles at high throughput, while maintaining the advantages of homogeneity, reproducibility, and tunability that are normally accessible only in specialized microscale mixing devices. Rapid mixing down to a timescale of 7 ms can be achieved by controlling the Reynolds number, providing homogeneous and controllable environments for formation of nanoparticles, for example, by precipitation. The device fabrication does not require specialized machining, making it accessible for a wide range of biomedical laboratories.

Abstract: A torque converter for a vehicle includes a front cover integrally formed with a boss to which a crank shaft of an engine side is connected, an impeller connected to the front cover to rotate together with the front cover, a turbine disposed facing the impeller, a stator disposed between the impeller and the turbine to convert flow of oil directed from the turbine, a lockup clutch mechanism for directly connecting the engine to the turbine. A blade of the impeller and/or the turbine is provided with inner and outer projections coupled to shell and core of the impeller and/or the turbine. Each of the inner and outer and inner projections includes a base located on a slit formed on the shell/core and an extending section extending from the base, the extending section being bent after penetrating the slit.
