Abstract: Methods of killing mosquito larvae and controlling an adult mosquito population by using ?-mangostin, 3,6,8-yrihydroxy-2-methoxy-1,7-bis(3-methylbut-2-enyl)xanthen-9-one, or a salt, solute, hydrate or solvate thereof. Mosquito larvae are killed by contacting a lethal dose of ?-mangostin with mosquito larvae. Adult mosquito populations are controlled by treating a mosquito larvae population with a lethal dose of ?-mangostin.

The light-emitting diode package includes an electrode pad on which a chip is placed; a housing having a window through which the chip is exposed; a housing wall defining the window; and an electrode lead extended from the electrode pad in a direction of the housing to be exposed outside a surface of the housing, wherein the housing wall formed in the direction comprises a first portion and a second portion thicker than the first portion to cover the electrode lead.

Abstract: Disclosed are nanoparticles for use in the isolation of peptides, a method for producing the nanoparticles, and a method for the isolation of peptides using the nanoparticles. The nanoparticles comprise magnetic nanoparticles and thiol-specific functional groups as first functional groups bound to the surfaces of the magnetic nanoparticles to selectively capture cysteine-containing peptides. The nanoparticles allow highly selective isolation of target peptides in a simple and rapid manner. Therefore, the nanoparticles can be applied to research on the treatment of diseases such as cancers.

Abstract: Provided are a method and apparatus for determining a security solution. The method and apparatus generate a security solution analysis model for analyzing effects on investment of security solution combinations consisting of several security solution candidates on the basis of integer programming (IP), standardize various constraints that have significant effects on security solution determination on the basis of IP, and apply the standardized constraints to the security solution analysis model, thereby determining a security solution combination having the smallest residual risk while satisfying the constraints as an optimum security solution combination. According to the method and apparatus, an optimum security solution combination that can minimize a residual risk while satisfying various constraints is rapidly and accurately determined. Thus, it is possible to support effective determination in information security investment.

Abstract: Provided are an apparatus, system and method for blocking malicious code. The apparatus includes a first malicious code detector for determining whether or not a received e-mail includes malicious code, on the basis of previously stored malicious code patterns, a second malicious code detector for performing second malicious code detection on a received e-mail determined by the first malicious code detector not to include malicious code, a pattern extractor for extracting a new malicious code pattern from malicious code detected by the second malicious code detector, and a transceiver for transferring the extracted new malicious code pattern to a pattern providing server.

Abstract: Provided is a method for enabling a user terminal to avoid exposure to a malicious code, by classifying web pages including a malicious code and blocking user access to the web pages including the malicious code when a user searches for a web page using a search engine. A method for managing malicious-code spreading sites using a search engine includes: analyzing a currently accessed web site to determine whether a malicious code is included in the web site; if the malicious code is included in the currently accessed web site, registering the web site as a malicious-code spreading site; and, if the web site registered as a malicious-code spreading site is included in a web-site search result from a search engine, blocking user access to the web site. Web pages including a malicious code are classified and user access to the web pages including the malicious code is blocked when a user searches for a web page using a search engine, thereby preventing a user terminal from being exposed to the malicious code.
