Abstract: The present invention relates to a scanner having a flexible probe which is an apparatus capable of being utilized for an inspection on a weld zone of a general ferrite material and a stainless material and allowing an inspection to be performed on a fitting weld zone where it is difficult for a general phased array ultrasonic testing (PAUT) probe to approach.

Abstract: Disclosed are a method for DNA extraction in a sample for next generation sequencing (NGS) and a method of constructing a NGS library using the extracted DNA. The method for DNA extraction includes: preparing a mixture by mixing a biological sample with a buffer; applying microwaves to the mixture; and recovering DNA. The method of constructing a NGS library includes: extracting DNA according to the method for DNA extraction; amplifying a target DNA using primers; and purifying the amplified product and subjecting the purified product to library pooling.

Abstract: Disclosed is a method of providing biological data. The method includes the following steps performed by a data processing device: selecting a biological data set from a biological data pool; encrypting biological data included in the biological data set to produce encrypted biological data; transferring the encrypted biological data to a user; receiving a result of analysis on the encrypted biological data from the user; and transferring information on the encrypted biological data included in the result of the analysis to the user. The data processing device encrypts the biological data with a key determined according to a combination of biological data constituting the biological data set.

Abstract: Disclosed is a method of providing bio-information data based on a plurality of blockchains. The method includes enabling a user blockchain node to store user block data including user information, a shared key, and a hash key for each user of a plurality of users, enabling an electronic contract blockchain node to store contract block data including contract information for a first user requesting a second user to generate bio-information data, the first user and the second user being included in the plurality of users, enabling a data transfer blockchain node to store transfer block data including storage information for at least one storage server that stores the bio-information data, and delivering the transfer block data from the data transfer blockchain node to the first user.

Abstract: Provided is a data sharing method based on a plurality of blockchains. The method includes registering, by a management server, user block data which includes user information and a hash key of each user of a plurality of users in a user information blockchain, receiving, by the management server, storage information of data provided by a first user from a storage server, and receiving, by the management server, a request for specific data from a second user and transmitting storage information of the specific data to the second user.
