Abstract: The disclosure relates to a composition for labeling a target lesion, in form of microspheres including a biocompatible polymer; and a dye for biological tissue, and directly administered to a target lesion to confirm size and location of the target lesion in real time during surgery at a target site and a method preparing the same. The composition for labeling a target lesion of the present disclosure, when injected into a target lesion, remains there for several months and can detect the location and size of the labeled lesion in real time during surgery, thereby not only improving the success rate of surgical operation for the target lesion, but also preventing excessive loss of normal tissue, and therefore can be widely utilized as an effective surgical marker.

Abstract: The present invention provides an alginic acid-based injectable hydrogel system for labeling an accurate position of a disease lesion and effectively delivering a drug to a target region. The formulation of the present invention can make it easy to locally inject a contrast agent and a drug into a target region while controlling the release rate of the contrast agent or the drug, with the formation of the hydrogel in the injected region. Through the advantages, the labeled position can be accurately determined from images, thereby enhancing the precision of surgical operation, with a minimal incision formed therefor. In addition, when used, the alginic acid-based injectable hydrogel system allows the effective local delivery of a drug to a target region while increasing the long-acting effect of the drug.

The scalable analog PIM module includes a first plural number of digital-to-analog converters (DACs), a first plural number of static random access memory (SRAM) calculators connected to the first plural number of DACs, at least one analog-to-digital converter (ADC) connected to the first plural number of SRAM calculators and configured to convert an analog convolution result signal into digital convolution data, and an analog PIM controller configured to output an enable control signal for enabling a second number, which is equal to or less than first plural number, of SRAM calculators among the first plural number of SRAM calculators to the first plural number of SRAM calculators on the basis of the convolution data output from the ADC.

Abstract: The present disclosure relates to a method and system therefor for providing a community service, such as a messenger, an SNS, and a metaverse in a virtual reality space where a physical range is defined by a Bluetooth beacon and, specifically, to the method and system for providing the service to allow a user terminal having received this, based on a range which this packet may reach, to use the community service through a wide area network within a variable yet clearly bounded physical space (Higgsverse), allowing the beacon to broadcast an arbitrary packet by utilizing a Bluetooth network. This makes it possible to physically interact with actual objects that exist within a space in which one currently exists.

Abstract: A battery includes a cell assembly, a pack frame accommodating the cell assembly therein, and a venting guidance portion coupled to the pack frame and configured to cause an outlet, through which venting gas emitted from the cell assembly is discharged to the outside of the pack frame, to be formed at a coupling portion with the pack frame, which is at least partially weakened as the internal pressure of the pack frame increases due to the venting gas.

Abstract: The present invention relates to a Corynebacterium glutamicum mutant strain having enhanced L-lysine productivity and a method of producing L-lysine using the same. The Corynebacterium glutamicum mutant strain is able to produce L-lysine in an improved yield as a result of improving the activity of glyceraldehyde 3-phosphate dehydrogenase by mutagenesis of amino acids in the gene encoding glyceraldehyde 3-phosphate dehydrogenase.

Abstract: A check cassette according to an embodiment of the present disclosure is a cassette which is used in a measurement device which allows an analyte of a biopsy sample to be measured on the basis of reaction properties of light irradiated from a light source including at least one of reflection, absorption, and transmission of the light (the measurement device provides an inner space into which a measurement cassette, in which the biopsy sample and at least one reagent react with each other, is inserted, and after the measurement cassette is inserted into the inner space, the analyte of the biopsy sample is measured on the basis of pieces of reaction property information of the light irradiated from the light source regarding a substance that results from the reaction between the biopsy sample and the at least one reagent) so that a change in light intensity of the light source in accordance with use of the measurement device is compensated for.

Abstract: The present invention provides a lateral flow immunoassay device for qualitative or quantitative analysis of an analyte of interest in a whole blood sample with a more rapid and accurate result. This device includes a sample receiving pad, a conjugate pad, a flow delaying pad and a wicking membrane in this order. A polycation is provided within and bound to the sample receiving pad in order to separate the red blood cell from the whole blood sample. A relation between average pore size (P1) of the sample receiving pad, average pore size (P2) of the conjugate pad, and average pore size (P3) of the flow delaying pad is as follows: P1>P2>P3.
