Abstract: A printed circuit board includes: a first board unit including a plurality of first insulating layers and a plurality of first wiring layers respectively disposed on or in the plurality of first insulating layers; a second board unit including one or more second insulating layers and one or more second wiring layers respectively disposed on or in the one or more second insulating layers; and a first passive device embedded in at least one of the first and second board units. The second board unit is disposed on the first board unit, and the first board unit has a second cavity passing through at least a portion of the plurality of first insulating layers on the first passive device based on a stacking direction of the plurality of first wiring layers.

Abstract: The present disclosure relates to a composition for antiobesity, which contains a Gynostemma pentaphyllum tea or a Gynostemma pentaphyllum tea extract as an active ingredient. The composition of the present disclosure, which contains a Gynostemma pentaphyllum tea or a Gynostemma pentaphyllum tea extract as an active ingredient, is effective for preventing, alleviating or treating diabetes, obesity, muscle loss, etc. since it exhibits the efficacy of increasing AMPK activity, promoting beta oxidation, promoting glucose uptake, etc. In addition, since the composition of the present disclosure is derived from a natural product, it can be safely used as a drug, food, etc. without side effects.

Abstract: The present invention relates to a lab-on-a-chip version of biosensor for an on-the-spot analysis whose analytical performances were remarkably improved, by incorporating commercial membranes, traditionally used for rapid diagnostics, into microfluidic channels engraved on the surface of a plastic chip, as follows: 1) reduction of sample size; 2) realization of variable functions for total analysis; and 3) transfer of medium by capillary action without the assistance of an external force.
