摘要:
A terminal having a stream control transmission protocol (SCTP)-based handover function and a SCTP-based handover method are provided. The terminal includes a session management unit which initiates a SCTP session for communication with a second terminal through the Internet and terminates a SCTP session established between the terminal and the second terminal for terminating communication between the terminal and the second terminal; a link layer information collection unit which receives beacon signals from a plurality of base stations connected to a router which is connected to the Internet and stores the beacon signals in a link layer state information database; a signal intensity extraction unit which, if theterminal enters an overlapping area of a first communication area managed by a first base station and a second communication area managed by a second base station while the SCTP session is established between theterminal and the second terminal, extracts the intensity of a beacon signal transmitted by the second base station from the link layer state information database; and a handover unit which, if the extracted beacon signal intensity is greater than a first critical value, adds an IP address received from the second base station to the SCTP session established between the terminal and the other terminal, and if the extracted beacon signal intensity is greater than a second critical value, requests the second terminal to communicate with the terminal using the IP address received from the second base station. Accordingly, it is possible to reduce investment in network equipment and offer an efficient handover method by adding a SCTP stack to a mobile terminal.

Disclosed is use of an antibody or antigen-binding fragment thereof that specifically binds to an acid sphingomyelinase (ASM) protein, wherein the antibody or antigen-binding fragment thereof specifically binds to an ASM protein with high binding affinity, significantly inhibits the activity of an ASM protein present in the cellular membrane, and shows effects of improving cognitive memory, inhibiting ASM protein activity, inhibiting the accumulation of amyloid-β and tau proteins, and inhibiting the production of neuroinflammation even without toxicity in Alzheimer's disease animal models, and thus can be advantageously used in the treatment of a brain disease.
摘要:
The present invention relates to a composition for preventing, alleviating or treating sarcopenia, containing D-ribo-2-hexulose as an active ingredient. D-ribo-2-hexulose of the present invention is a sweetener capable of replacing sugar, is harmless to the human body and does not cause side effects in normal cells so as to be safe for the human body, inhibits the degradation of myoproteins, and can exhibit muscle strengthening effects by increasing muscle mass, and thus the present invention is expected to be effectively usable in the prevention, alleviation or treatment of sarcopenia.
摘要:
The present invention relates to a preparation method for an organic halide used for preparation of perovskite, perovskite prepared thereby, and a solar cell. According to the present invention, an organic halide used for perovskite may be prepared by an ion-exchange method using alkali metal iodide or alkali metal bromide.
摘要:
A photosensor is disclosed. The photosensor comprises: a vacuum tube providing an inner space in which photoelectrons move; a photocathode disposed at the top of the vacuum tube and converting light that is incident from the outside into photoelectrons; a scintillator unit reacting with the photoelectrons to generate scintillation light; and a photomultiplier element converting the scintillation light into photoelectrons and multiplying the converted photoelectrons to generate an electrical signal.
摘要:
The present invention relates to a composition containing IL-2 or an expression promoter or activator thereof as an active ingredient for prevention or treatment of cancer disease. In the present invention, it was discovered that when treating cancer cells with IL-2, an anticancer effect was enhanced by inhibiting the secretion of cancer cell-derived exosomes and the expression of PD-L1 inducing immune escape of T cells. IL-2 was also discovered to effectuate the anticancer effect directly on cancer cells compared to conventional techniques exhibiting an immune anticancer effect by activating cytotoxic T cells. Thus, IL-2 or an expression promoter or activator thereof can be advantageously used in a composition for prevention or treatment of cancer diseases.

摘要:
The present invention relates to a composition for preventing or treating neurodegenerative diseases or depression, containing a 2-amino-2-(1,2,3-triazole-4-yl)propane-1,3-diol derivative as an active ingredient and more specifically, to a pharmaceutical composition for preventing or treating neurodegenerative diseases or depression, containing, as an active ingredient, the compound having an effect of directly inhibiting ASM activity.
摘要:
The present invention relates to a peptide bound to CD44v6 and uses for inhibiting cancer metastasis using the same, and the peptide of the present invention specifically binds to CD44v6 and inhibits it, thereby inhibiting cancer cell migration and metastasis. The peptides of the present invention selected two peptides (v6Pep-1 and v6Pep-2) that bind well to cells with high expression of human CD44v6 protein using phage peptide display technology and it was confirmed that it interferes with the binding between c-Met and CD44v6 to inhibit cancer cell migration. The peptide of the present invention is relatively stable in serum and shows a high potential as an anticancer treatment agent that suppresses metastasis due to the progression and migration of cancer in the future.
