A method for preventing corrosion of a spent nuclear fuel canister by using electrolytic corrosion protection, according to the present invention, has an effect of enabling a semi-permanent operation and, particularly, has effects of preventing oxidation and corrosion problems of a canister made of a metal material, in consideration of various environmental variables that may cause corrosion, and ensuring the structural stability of the canister so as to enable a semi-permanent operation.

Disclosed are an airplane system including duplex modules, and a control method thereof. The control method of the airplane system includes: receiving, by each of a plurality of duplex modules, a corresponding event command from a client; performing, by a first module, a first event specified by the event command in response to the event command; performing, by a second module different from the first module, a second event specified by the event command after the first event is completed; and returning a first response signal indicating a result of the performance of the first event and a second response signal indicating a result of the performance of the second event to the client, in which the client compares the first response signal and the second response signal, and determines whether the plurality of duplex modules is synchronized or has an error.

Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.
