Abstract: Disclosed is a pharmaceutical composition for the prophylaxis and therapy of inflammatory diseases, allergic diseases, or asthma, comprising a velvet apple (Diospyros blancoi A. DC.) extract as an active ingredient. Having the inhibitory activity against the nuclear translocation of NF-?B, whose level is rapidly elevated in response to inflammatory stimuli, the velvet apple extract can suppress the production of NO and PGE2, the expression of iNOS and COX-2, and the release of IL-1? and TNF-?, and can significantly down regulate Th2-mediated IL-4 and IL-13 production. In addition, the extract was found to inhibit the activation of eosinophils in bronchoalveolar lavage fluid, and to suppress the secretion of immunoglobulins and chemokines in bronchoalveolar lavage fluid and blood, as measured by in vivo tests on an ovalbumin-induced asthma mouse model. Therefore, the extract can be used in the method for preventing or treating various inflammatory disorders, allergic diseases, or asthma.

Abstract: Provided is a method of identifying an ActiveX control distribution site, detecting a security vulnerability in an ActiveX control and immunizing the same. A security vulnerability existing in an ActiveX control may be automatically detected, effects brought on by the corresponding security vulnerability may be measured, and abuse of the detected security vulnerability in a user PC to be protected may be immediately prevented. Therefore, since the user PC may be protected regardless of a security patch, it is anticipated that security problems in the Internet environment caused by imprudent use of the ActiveX control may be significantly enhanced.

Abstract: A method of controlling a servo in an optical disc device and a servo control device using the method, in which the servo control device controls a servo for printing on a label surface of an optical disc and includes an optical pickup unit, an error signal generation unit, and a control unit. The optical pickup unit outputs a plurality of signals corresponding to a position of an object lens in response to light reflected from the label surface. The error signal generation unit outputs an error signal by selecting or combining one or more of the plurality of signals. The control unit adjusts the position of the object lens in response to the error signal. Therefore, because the position of the object lens can be adjusted with an increased range, the spot size of a beam condensed by the object lens can be adjusted within an increased range, and a data recording time can be reduced. Moreover, data retention characteristics and recording quality can be improved.
