A method and system for implementing activity-oriented access control (AOAC) to hospital information is disclosed. An access request device sends user credentials attaching user attributes to an AOAC server, which in turn searches activity rules that are assigned to user attributes from an activity server and a current work situation of the user from an activity recognition server. The AOAC server transmits an access request list corresponding to the activity rules and the current work situation of the user to the access request device so that it can select a desired access request among the list.

Disclosed is a behavior-based method which uses each rater's rating behaviors as the criterion to judge unfair ratings. A behavior refers to the action that a rater gives certain rating under specific context. The behavior-based method regards the rating given by a rater with abnormal behavior as an unfair rating, where abnormal behavior is recognized by comparing a rater's current behavior with his behavior history.

Disclosed is a method for enhancing blood vessels in angiography images. The method incorporates the use of linear directional features present in an image, extracted by a Directional Filter Bank, to obtain more precise Hessian analysis in noisy environment and thus can correctly reveal small and thin vessels. Also, the directional image decomposition helps to avoid junction suppression, which in turn, yields continuous vessel tree.

A process chamber used in the manufacture of a semiconductor device for etching a material layer on a semiconductor wafer includes an electrostatic chuck for holding the semiconductor wafer, and an annular edge ring which surrounds the side of the semiconductor wafer on the electrostatic chuck to prevent the semiconductor wafer from departing from its original position. The annular edge ring has a first side which faces the side of the semiconductor wafer and contacts firmly with the side of the semiconductor wafer.

The present invention relates to a user preference-based data adaptation service system and method. More particularly, the present invention relates to a user preference-based data adaptation service system and method capable of providing a data adaptation service that appropriately converts a file in consideration of a difference between the platforms of different kinds of devices in order to share the file, and reflecting an exact user preference in consideration of the surrounding environments, such as, the performance of the device and a network.

Disclosed are methods for determining the neighborhood local view of a mobile node in time which can facilitate the forwarding decision in the design of network protocols. In conventional mobile ad hoc networks nodes set up local topology view based on periodical received “Hello” messages. The conventional method is replaced with proactive and adaptive methods of predicting locations of nodes based on preserved historical information extracted from received “Hello” messages and constructing neighborhood view by aggregating predicted locations. This method is useful for providing updated and consistent topology local view that a network communication employs to determine optimal forward decisions and improve communication performance.

A method for implement an energy-efficient user access control to wireless sensor networks is disclosed. A user creates a secret key and sending it to a sensor. The sensor builds a first MAC value by the secret key and sends it to the Key Distribution Center which builds a second MAC value and sending it to the sensor. The sensor decrypts the second MAC value to get a random number, and builds a third MAC value by the random number. The third MAC value is used by the user to authenticate the sensor.

Disclosed herein is a recovery method in a storage system that integrates shadow page and deferred update techniques. In our invention, for update operations that occur during a transaction, update of a page in the buffer is not immediately reflected to the database, but is deferred until the transaction is committed. Instead, we store the updated buffer page in the log volume in the unit of a page. When reading a page that does not exist in the buffer from the disk, we read the up-to-date page from the database or from the log volume. Here, the log table index is used to determine whether the up-to-date page exists in the database or in the log volume and to identify the position of the page stored in the log volume if the up-to-date page exists in the log volume. The proposed invention has the following excellent advantages. It is simple and efficient because the deferred update file does not have to be additionally accessed for correct query processing. Besides, there is no performance degradation because the position of an updated page in the database is not changed, and thus, the original clustering of logically related data is preserved.
