Abstract: An automatic two-component resin inspection device for automatically determining in real time whether a two-component resin injected into a battery module is normal, an automatic two-component resin inspection system including the same, and an automatic two-component resin inspection are provided. The automatic two-component resin inspection device includes a housing with an open lower part, a lighting unit configured to emit light toward the open lower part of the housing, a camera unit configured to obtain a resin image by photographing a two-component resin injected into a battery module under the open lower part of the housing, and a determiner configured to determine whether the two-component resin injected into the battery module is normal on the basis of color information of the resin image obtained by the camera unit.

Abstract: The present invention relates to a security method for a smart phone, in which method a security keyboard app is installed in a smart phone of a staff member so as to make it possible to monitor information leakage. The security method for a smart phone comprises the steps of: running a first app on a smart phone and, when the first app is subject to key input, determining, by means of a security keyboard app installed in the smart phone, whether the first app is a predetermined app which is to be subject to security; monitoring the key input which is inputted to the first app, if the first app is a predetermined app that is to be subject to security; transmitting the monitored key input to a security server; and blocking the key input if the monitored key input includes a predetermined security key word.

Abstract: The present invention relates to a technology that performs: checking an integrity of a paravirtualization agent before executing the paravirtualization agent; protecting the paravirtualization agent by obstructing the modulation of a memory region to which the paravirtualization agent is allocated; when file input-output is generated in the paravirtualization agent, transmitting information associated with the generated file input-output to a host-based file system protection service to inquire about accessibility; determining an authority for access to the generated file input-output through a reasoning engine in the host-based file system protection service; and transmitting a result of the determination to the paravirtualization agent, and processing the generated file input-output, thereby protecting a file in a file system.

Abstract: A smart phone according to an embodiment of the present invention suggests a method for accessing dual environments in a lock screen. The method may comprise: a step for receiving an inputted password or release pattern in a lock screen of a smart phone; and a step for providing smart phone environments different from each other according to the inputted password.

Abstract: The present invention relates to a method of implementing a security system for preemptively preventing a decrease in work efficiency due to leaked confidential secrets or the browsing of non work-related sites through a mobile terminal. A security manager implements an environment for allowing, blocking, or recording Internet usage in an independent mobile communication network in an area requiring security, uses a security system server to preregister information on mobile terminals of users who are expected to use the Internet, makes agreements on how personal information will be handled when outside visitors visit the network, registers information on mobile terminals of outside visitors with the security system server, and oversees the installation of a security app whenever necessary.

Abstract: A lens optical system including first, second, third, fourth, and fifth lenses that are sequentially arranged between an object and an image sensor on which an image of the object is formed. The first lens may have a positive refractive power and may be biconvex. The second lens may have a negative refractive power and may have a meniscus shape that is convex toward the object. The third lens may have a positive refractive power. The fourth lens may have a positive refractive power and may have a meniscus shape that is convex toward the image sensor. The fifth lens may have a negative refractive power, and at least one of an incident surface and an exit surface of the fifth lens may be an aspherical surface.
