Provided is a method of managing a database (DB) using a high availability database management system (DBMS), which continuously provides a service when an error occurs in the DBMS. The DB management method in the high availability DBMS including a plurality of broker nodes and a plurality of server nodes may include an operation (a) to enable one of the plurality of broker nodes to access a main server node of the plurality of server nodes when a DB change request is received from an application server, and an operation (b) to enable the main server node to process the DB change request when the broker node succeeds in accessing the main server node, and to enable the broker node to access one of sub-server nodes so that the sub-server node processes the DB change request when the broker node fails to access the main server node due to an error in the main server node.
摘要:
Provided are a method and a wireless device for transmitting an uplink. The wireless device transmits a random access preamble to a first serving cell through a first wireless resource, and transmits an uplink channel to a second serving cell through a second wireless resource. The first serving cell belongs to a first timing advance (TA) group, and the second serving cell belongs to a second TA group that differs from the first TA group. All or a portion of the first wireless resource and the second wireless resource overlap.

An apparatus, system, and method for providing augmented reality (AR) information of a concealed object are disclosed. The method for providing AR information of a concealed object by a terminal connectable to a server via a wired and/or wireless communication network may include acquiring an image of a real environment; defining a reference object included in the acquired image; obtaining image capturing position information about a position of the image and reference object recognition information of the defined reference object; transmitting the obtained image capturing position information and the reference object recognition information to the server; receiving information about concealed objects from the server, the concealed objects being disposed behind the reference object along or about a direction from the image capturing position to the reference object; and outputting the received information about concealed objects.
摘要:
A semiconductor wet etchant includes deionized water, a fluorine-based compound, an oxidizer and an inorganic salt. A concentration of the fluorine-based compound is 0.25 to 10.0 wt % based on a total weight of the etchant, a concentration of the oxidizer is 0.45 to 3.6 wt % based on a total weight of the etchant, and a concentration of the inorganic salt is 1.0 to 5.0 wt % based on a total weight of the etchant. The inorganic salt comprises at least one of an ammonium ion (NH4+) and a chlorine ion (Cl−).

A user equipment receives a measurement con figuration which configures a plurality of serving cells as measurement objects and performs measurements for the plurality of serving cells based on the measurement configuration to determine measurement results for the plurality of serving cells. The user equipment reports the measurement results for the plurality of serving cells.
摘要:
The present invention discloses an isolated pure culture of a novel strain CK1 of Bacillus licheniformis, BCRC 910458, capable of detoxification of zearalenone (ZEN). Using physiological, biochemical, morphological identification and 16S rRNA gene sequence analysis methods, the strain CK1 was identified as Bacillus licheniformis. Through extracellular xylanase, CMCase protease assays and evaluations for zearalenone detoxification, the strain CK1 strain was identified to possess good ZEN-detoxifying ability, to be non-hemolytic, non-enterotoxin producing, and displayed high levels of extracellular xylanase, cellulase, and protease activities. Accordingly, Bacillus licheniformis CK1 can be applied as food and feed supplement for bio-detoxification of ZEN.

Provided is an apparatus and method for analyzing contaminants on a wafer. The apparatus includes: a wafer holder for supporting a wafer on which contaminants to be analyzed are located, a laser ablation device for irradiating a laser to the wafer to extract a discrete specimen from the wafer, an analysis cell for collecting a discrete specimen from the surface of the wafer by irradiating the laser, and an analysis device connected to the analysis cell for analyzing contaminants from the collected discrete specimen.
摘要:
A spin transistor comprises a semiconductor substrate part having a lower cladding layer, a channel layer and an upper cladding layer sequentially stacked therein, a ferromagnetic source and drain on the substrate part, and a gate on the substrate part to control spins of electrons passing through the channel layer. The lower cladding layer comprises a first lower cladding layer and a second lower cladding layer having a higher band gap than that of the first lower cladding layer. The upper cladding layer comprises a first upper cladding layer and a second upper cladding layer having a higher band gap than that of the first upper cladding layer. The source and the drain are buried in an upper surface of the substrate part and extend downwardly to or under the first upper cladding layer.
