Abstract: The present invention relates to a nanobody or an antigen binding fragment thereof, and a pharmaceutical composition for preventing or treating a mental or neurological disease, which includes the nanobody or antigen binding fragment thereof. The nanobody or antigen binding fragment thereof according to the present invention binds to proteins (i.e., C1, C3, or C4) of the complement system to inhibit or interfere with their activity, thereby preventing a decrease in dendritic spines in nerve cells, and thus effectively improving the positive and negative symptoms of schizophrenia. In particular, the nanobody or antigen binding fragment thereof according to the prevent invention has an excellent advantage in that it may improve the negative symptoms of schizophrenia, which were difficult to treat in the past.

Abstract: Disclosed are a method of estimating PV model parameters and a method and an apparatus for data-based PV fault detection and diagnosis using a PV model. The method comprises: substituting five parameters of a PV current, a diode saturation current, a diode ideality factor, a series resistance, and a parallel resistance into an output equation of a single diode model for PV modeling of a PV module; computing an MAEP in an output by comparing power-voltage (P-V) curve values of the PV module obtained from the single diode model, which is a PV simulation model, and P-V curve values of the PV module, which is an actual PV module, when the voltage is zero, the open-circuit voltage, or a specific data value increased as much as a preset intensity; and selecting parameters representing a minimum MAEP among a plurality of stored MAEPs as parameters of the PV simulation model.
