A test device includes a main board. First and second device under test (DUT) boards are disposed on the main board. First and second semiconductor devices are mounted on the first and second DUT boards, respectively. The first and second semiconductor devices are DUTs. First and second connectors are respectively disposed at a first end and a second end of the first DUT board. The first and second connectors are spaced apart from each other and respectively transmit first and second signals. The first signal forms a first electrical path along which the first signal is input to the first DUT board via the first connector. The second signal forms a second electrical path along which the second signal is output from the first DUT board and input to the second DUT board via the second connector.

The present disclosure relates to technology that performs encrypted communication via a network or a bus, and a communication method using a security key between nodes connected via a network or a bus includes setting a critical cluster among multiple nodes, selecting a primary message shared between the set critical clusters, and encrypting a message using a key generated to be valid for a preset period to enable communication between the critical clusters, wherein each of the critical clusters stores the primary message for the preset period according to a same key generation scheme to generate a block, and generates and possesses a new key based on the generated block and a currently used key, so that information about a previous message and a previous key is sequentially accumulated in the new key.

Communication device and method using message history-based security key by means of blockchain

The present disclosure relates to a search technology using a data structure for supporting multi-search in a blockchain-based IoT environment, and a method for providing a search function for blockchain includes receiving block data via a network, verifying transactions included in the received block data, and adding the block data as a node to an index tree of multidimensional index structures based on information about each transaction in the transaction verification.

An apparatus and method for recommending software process improvement are disclosed. The method includes generating improvement packages from correlated findings by analyzing correlations between findings identified from different processes, refining the improvement packages by performing an additional correlation analysis on the improvement packages, and providing an action plan for process improvement by building recommendations from the refined improvement packages.

Apparatus and method for recommending software process improvement

A method and apparatus for authoring an architecture for transforming a single-core based embedded software application to a multi-core based embedded software application, and a method of determining an architectural pattern in a multimedia system. It is possible to perform an architecture authoring operation by using an architectural decision supporter, without prior knowledge and accumulated knowledge regarding a software architecture. Additionally, it is possible to prevent an error from occurring during authoring of an architecture, by using a concurrency-related software architectural pattern that is already evaluated. Thus, it is possible to improve overall quality of software, and to reduce a development time.
