Abstract: A violation checking method includes generating a violation log report for a design, classifying violation logs in the violation log report into high-risk logs and low-risk logs by a machine learning model, reviewing the high-risk logs, and modifying the design if at least one bug is identified in the high-risk logs.

Abstract: A health care device and a health care method are illustrated, the health care method is used to arrange the health care device at a predetermined location in front of a belly button of a user with a predetermined distance, and to emit the low-frequency wave with a predetermined frequency to the belly button by using a low-frequency wave emitter. The health care device is formed by the low-frequency wave emitter and a cone/pyramid part. The predetermined frequency is 1.27 Hz to 1.81 Hz, and the predetermined distance is 5 cm to 8 cm. The above health care device and method can increase contents of active T cells and B cells in blood and increase an ability of NK cell strains for poisoning cancer cell strains (K562). In short, the above health care device and method have health benefits without a risk of excessive energy causing harm.

Abstract: A bed structure includes a first body, a second body, a third body, a supporting frame, a first driving assembly and a second driving assembly. The first body extends to form a first arm and a second arm. The distal ends of the first arm and the second arm are provided with a sliding element respectively sliding in a guiding rail of the supporting frame. By this arrangement, the inclination of the bed structure of the present invention can be adjusted smoothly, so that a user lying thereon can feel more comfortable.
