Abstract: The present invention relates to a mesenchymal stem cell having immunomodulatory activity and a preparation method therefor and, more specifically, to: a rapamycin-treated mesenchymal stem cell having immunomodulatory activity, which expresses any one or more cell surface factors selected from the group consisting of CCR1, CCR2, CCR3, CCR4, CCR7, CCR9 and CXCR4; a cell therapy composition comprising the mesenchymal stem cell, for preventing or treating immune disorders; and a preparation method for the mesenchymal stem cell having immunomodulatory activity. The rapamycin-treated mesenchymal stem cell having immunomodulatory activity, according to the present invention, has increased expression of IDO, TGF-? and IL-10 which are factors having immunomodulatory activity, has decreased expression of Phospho-mTOR, Rictor and Ractor which are signal transduction factors of mTOR, and has increased expression, in the cell, of autophagic inducer Beclin1, ATG5, ATG7, LC3I or LCII.

Abstract: The present invention relates to an ink container for an inkjet printer, the ink container being configured to prevent a problem caused by fine bubbles accumulated in the ink container. As the ink container containing ink for supplying ink to an inkjet head having a plurality of nozzles that discharge ink, the ink container includes: a bottom surface inclined so that a first side thereof connected to a return line through which ink is returned from the inkjet head is positioned higher than a second side thereof connected to a supply line through which ink is supplied to the inkjet head; and a bubble removing net provided between the supply line and the return line to remove bubbles from ink contained in the ink container.

Abstract: The present invention relates to a biguanide derivative compound capable of effectively preventing and treating immune diseases. The biguanide-based derivative compound according to the present invention inhibits the generation of IL-17 and TNF-?, which are inflammatory cytokines, increases the activity of regulatory T cells having an immunomodulatory function, and exhibits excellent therapeutic effects in animal models of immune diseases. Accordingly, the biguanide-based derivative compound can be usefully used as an immunosuppressant or a pharmaceutical composition capable of preventing or treating various immune diseases, such as autoimmune diseases, inflammatory diseases, and transplant rejection, caused by the dysregulation of immune responses.

Abstract: The present invention relates to a pressure adjusting device which maintains the precision of pressure control even during use of the inkjet printer and the pressure adjusting device includes an output tube which is connected to an ink reservoir; at least one pressure generator which is capable of changing the pressure in the ink reservoir; an adjusting valve which is positioned between the pressure generator and the output tube; a control unit which controls the adjusting valve to control an output pressure; a pressure sensor which measures pressure information which is output to the output tube so that the control unit is capable of adjusting the adjusting valve; and a temperature sensor which measures temperature information so that the control unit is capable of performing a temperature correction with respect to the pressure information measured at the pressure sensor.
