A method and apparatus for blocking harmful multimedia information are provided. The apparatus for blocking harmful multimedia information includes: a harmful information classification model training unit analyzing multimedia training information whose grade of harmfulness is known in advance, extracting characteristics from the information, and then by applying machine training, generating a harmful information classification model; a harmful information grade classification unit determining a harmfulness grade of multimedia input information by using the harmful information classification model; and a harmful information blocking unit blocking the multimedia input information if the determined harmfulness grade of the multimedia input information is included in a preset range. According to the method and apparatus, the increase of databases containing harmful multimedia information can be prevented and the time taken for determining harmfulness can be reduced.

An apparatus and method for collecting harmful web sites are provided. In the apparatus, a start uniform resource locator (URL) database (DB) stores URLs of harmful web pages. A URL examination and distribution unit provides URLs grouped in relation to predetermined hosts, the URLs obtained by removing redundant URLs that are different to each other but indicate identical web pages, among the URLs stored in the start URL DB, and then among the remaining URLs, removing URLs corresponding web sites already collected. A web site collection unit collects web contents of the web sites corresponding to the URLs received from the URL examination and distribution unit. A URL extraction unit extracts URLs in the links included in the web contents collected by the web site collection unit, identifies harmless URLs based on top-level domain names and a harmless URL list among the extracted URLs, and removes the identified harmless URLs from the URLs that are the object of the collection. According to the apparatus and method, the harmful site database is helped to maintain accurate, abundant, and latest information.

摘要:
An epoxy resin composition for encapsulating a semiconductor device includes a curing agent, a curing accelerator, inorganic fillers, and an epoxy resin, the epoxy resin including a first resin represented by Formula 1: wherein R1 and R2 are each independently hydrogen or a C1 to C4 linear or branched alkyl group, and n is a value from 1 to 9 on average.
摘要:
Disclosed herein is an interdigitation-type diffractive light modulator. In the interdigitation-type diffractive light modulator of the present invention, each of a pair of ribbons has a plurality of diffractive branches which are arranged in a comb shape, and the diffractive branches of the ribbons interdigitate with each other. Furthermore, the respective ribbons moves upwards and downwards or, alternatively, one ribbon moves upwards and downwards, so that the diffractive branches of the ribbons which interdigitate with each other form a stepped structure, thus diffracting incident light.

The present invention relates, in general, to a light modulator having a variable blaze diffraction grating and, more particularly, to a light modulator having a variable blaze diffraction grating, in which a diffraction member rotates due to piezoelectric force so as to incline a reflective surface.
摘要:
A method for fabricating a semiconductor device is disclosed in which a doping depth of an ion implanted dopant is prevented from being increased during annealing, so as to form a junction having a depth of 20 nm or below without any problem in the technology of 65 nm or below. The method includes the steps of a) implanting ions into a silicon substrate provided with a predetermined structure, b) applying tensile stress to a surface of the substrate, and c) annealing the substrate.
