Disclosed are a composite rim of a vehicle wheel and a method of manufacturing the same, which is reduced in weight through the use of a continuous fiber composite. The rim of a vehicle wheel may be formed by stacking composite sheets, each prepared by impregnating fibers with a resin to form a sheet. The composite sheets may be stacked in multiple layers such that end portions of the respective composite sheets may contact each other in a circumferential direction of the wheel, and discontinuous interfaces, formed at the contacting end portions of the respective composite sheets along an axial direction of the wheel, may not be aligned with each other.

Composite rim of vehicle wheel and method of manufacturing the same

There are provided an inductor and a method of manufacturing the same. The inductor includes: a body including a plurality of coil layers and high-rigidity insulating layers disposed on and beneath the plurality of coil layers; and external electrodes disposed on external surfaces of the body and connected to the coil layers. Build-up insulating layers are disposed between the high-rigidity insulating layers to cover the coil layers, and the high-rigidity insulating layers have a Young's modulus greater than that of the build-up insulating layers.

Inductor including high-rigidity insulating layers

Provided is an ultrasound imaging apparatus for predicting fetal growth rate, including: an ultrasound probe configured to transmit ultrasound signals to a fetus and receive ultrasound echo signals reflected from the fetus; a user inputter configured to receive pregnancy information regarding a patient from a user; a communicator configured to receive, from a cloud server, fetal biometric data related to the pregnancy information regarding the patient from among fetal biometric data prestored and accumulated in the cloud server; and a controller configured to generate an ultrasound image of the fetus by using the ultrasound echo signals, measure a size of a body part of the fetus on the ultrasound image, and predict the fetal growth rate based on the measured size of the body part of the fetus and the fetal biometric data received from the cloud server.
