Abstract: Provided is an optical system which may acquire a hyperspectral image by acquiring a spectral image of an object to be measured, which includes, to collect spectral data and train the neural network, an image forming part forming an image from an object to be measured and transmitting collimated light, a slit moving to scan the incident image and passing and outputting a part of the formed image, and a first optical part obtaining spectral data by splitting light of the image received through the slit by wavelength. Also, the system includes, to decompose overlapped spectral data and to infer hyperspectral image data through the trained neural network, an image forming part forming an image from an object to be measured and transmitting collimated light, and a first optical part obtaining spectral data by splitting light of the received image by wavelength.

Abstract: An apparatus and a method for detecting network congestion based on a destination node are provided. To elaborate, the apparatus may include: a physical information extraction unit that extracts physical information of an electrical signal received through an antenna of the destination node; a MAC information extraction unit that extracts a size of a MAC frame payload from a MAC frame on the basis of the extracted physical information; a TCP information extraction unit that extracts a size of service data included in the MAC frame payload; a data size comparison unit that compares the size of the MAC frame payload with the size of the service data and generates comparison result data; and a congestion detection unit that receives the comparison result data, compares the comparison result data with a predetermined threshold value, and determines presence or absence of network congestion.

Abstract: The present invention relates to a transformed plant cell expressing ?-amyloid gene, which is known as a causal substance of senile dementia in human, a transformed plant and a preparation method of the same, more particularly, to a transformed plant cell expressing tandem repeats of ?-amyloid gene, a transformed plant produced by tissue-culturing the above cells and a preparation method of the same. The transformed plant of the present invention expresses multiple ?-amyloid protein, so that the plant can be effectively used for the preparation of an oral vaccine composition for the prevention of senile dementia in human.
