Abstract: In a method of killing or reducing a growth of methicillin-resistant Staphylococcus aureus (S. aureus), a composition including a peptide consisting of the amino acid sequence of SEQ ID NO:2 or 3 is administered to a subject in need thereof. The peptide can be usefully applied as an active ingredient for antibiotics, cosmetic compositions, food additives, feed additives, biological pesticides and quasi-drugs.

Abstract: A server for performing an operation on a homomorphic ciphertext is configured to: receive a first homomorphic ciphertext, a public key, and a first hierarchical Galois key set from a client device; in response to a request for generating a second hierarchical Galois key set for performing a rotation operation on the first homomorphic ciphertext of the client device, generate the second hierarchical Galois key set, based on the received public key and hierarchical Galois key set; and when a decomposition operation for a first Galois key included in the second hierarchical Galois key set overlaps with a decomposition operation for a second Galois key, first perform the decomposition operation for the first Galois key, and then substitute the decomposition operation for the second Galois key with a result of the decomposition operation for the first Galois key.

Abstract: Light is irradiated to a finger of a subject and received from the finger of the subject to extract a pulse wave signal, generates an optimized pulse wave signal in a desired type by sampling the extracted pulse wave signal according to a predetermined sampling condition and normalizes the generated pulse wave signal, the entire segment of the normalized pulse signal is divided into a plurality of window segments to detect a pulse wave amplitude value with respect to a pulse wave signal for each window, a first eigenvector for each subject corresponding to a pulse wave amplitude value of the entire window segment is extracted by using a linear discriminant analysis and then the first eigenvector per subject is compared with a threshold, determines distribution of eigenvectors for each subject compared to the threshold and thus a characteristic of the corresponding subject is diagnosed.
