摘要:
A measurement system and a measurement method, which can obtain a measurement value close to a true value considering an overlay measurement error according to a higher order regression analysis model. The measurement system and the measurement method provide a technique for determining optimal positions of shots to be measured using an optimal experimental design. When the regression analysis model and the number of shots to be measured are determined in advance, a method is used for determining an optimal number of shots to be measured according to the regression analysis model and process dispersion using a confidence interval estimating method. A dynamic sampling method is used for dynamically changing the number and positions of shots to be measured according to a change in process features by combining the above two methods. And, when erroneous data is detected, or when measured data is missing, a robust regression analysis method and a technique for filtering the erroneous data and the missing data are used.

The present invention relates to a method for recovering an organic-inorganic element-doped metal oxide from a hydrolysable metal compound, accompanied with contaminated water treatment. The present invention comprises steps of: a) adding a hydrolysable metal compound as a coagulant to a contaminated water to form a separable floc between the hydrolysable metal compound and contaminants present in contaminated water; b) separating the separable floc and the pre-treated water after flocculation treatment; and c) calcinating the separated floc over 500° C. to produce an organic-inorganic element-doped metal oxide. More preferably, the present invention further comprises subjecting the pre-treated water of the step b) to a microwave treatment to cause a photocatalytic degradation of an organic contaminant that remains in the pre-treated water, with the assistance of the remaining hydrolysable metal compound. A novel titanium compound is found as an alternative coagulant instead of iron and aluminum salts which most widely use in water treatment. Ability, capacity and efficiency of flocculation as the proposed titanium coagulant are similar to those of FeCl3 and alum coagulants in terms of removing organic matter. Titania produced by calcination of the separated floc after TiCl4 flocculation is mainly doped with C and P atoms.

An apparatus and method for providing a service that securely and easily shares personal information using a signed callback uniform resource locator (URL) message in a mobile terminal environment are provided. The mobile terminal providing a personal information sharing service using a signed URL message includes; a personal information sharing service module which receives a message that includes a first callback URL and a personal information sharing request and is signed using a private key of a server, and creates a second callback URL by adding a user response result in response to the personal information sharing request to the first callback URL; and an authentication module which verifies a signature of the message using a public key of the server, and signs the second callback URL using a user private key.

A method and system for transmitting and receiving user's personal information using an agent are provided. An information management server managing user's personal information provides an agent including user's personal information in response to a user's personal information request message from a client. A client receives the agent and requests user's personal information from the agent. Then, the agent determines whether the client is authorized and provides the user's personal information to the client when it is determined that the client is authorized. Accordingly, the user's personal information is safely managed and transmitted.
