Abstract: A method of alleviating cognitive impairment includes performing control such that a first domain training algorithm, a second domain training algorithm, and a third domain training algorithm of a first phase are output on the user terminal, determining whether the first domain training algorithm, the second domain training algorithm, and the third domain training algorithm of the first phase are completed, and determining whether the first phase is normally terminated, performing control such that a first domain training algorithm, a second domain training algorithm, and a third domain training algorithm of a second phase are output on the user terminal, determining whether the first domain training algorithm, the second domain training algorithm, and the third domain training algorithm of the second phase are completed, and determining whether the second phase is normally terminated, and performing control such that a first visual indication is output on the user terminal.

Abstract: The present disclosure relates to an apparatus and method for diagnosing Alzheimer's disease based on an analysis of speech data of a speaker. According to the present disclosure, the method of diagnosing Alzheimer's disease is performed by a processor of an Alzheimer's disease diagnosis apparatus, and may include collecting speech data of a speaker, extracting features of the speech data, and generating, based on the features of the speech data, at least one of an Alzheimer's disease classification result and a cognitive function assessment score prediction result.

Abstract: The present disclosure relates to a structure for surface-enhanced Raman scattering spectroscopy, a method of preparing the same, and a diagnostic method using the same. According to the structure for surface-enhanced Raman scattering spectroscopy, the method of preparing the same, and the diagnostic method using the same, of the present disclosure, a structure for surface-enhanced Raman scattering spectroscopy and a method of preparing the same may be provided, which can be used even when biomarkers with excellent diagnostic performance among blood indicators do not exist, as in the case of intractable cancer, such as pancreatic cancer, and intractable diseases. Also, a diagnostic method and diagnostic system using surface-enhanced Raman scattering spectroscopy may be provided by using the structure for surface-enhanced Raman scattering spectroscopy.

Abstract: Provided is a method of implementing an application for improving mild cognitive impairment symptoms, wherein the method includes: controlling a first training algorithm to be output to a user terminal in response to an input into the user terminal; in a case where the first training algorithm is terminated, controlling a second training algorithm to be output to the user terminal; in a case where the second training algorithm is terminated, evaluating user inputs into the first training algorithm and the second training algorithm; and on the basis of a result of the evaluation, controlling a first visual display to be output to the user terminal.

Abstract: A method of determining a visual fatigue occurrence duration includes: receiving an eye image that is an image including a plurality of frames and obtained by photographing an eye of a measurement target; determining a size of a pupil by analyzing the eye image; calculating each of a number of eye blinks, an eye closed time, and a pupil size change speed on the basis of an unspecified number of times and a change in the size of the pupil, in some frames of the determined pupil in the eye image; and determining a duration in which visual fatigue of the measurement target occurs, from among the plurality of frames, as a result of combining information regarding the calculated number of eye blinks, eye closed time, and pupil size change speed.

Abstract: The present disclosure relates to a dementia diagnosis system using a story-based question-and-answer-type assessment, for quickly and easily diagnosing dementia without using expert personnel, enabling early dementia diagnosis and quick and accurate screening of patients with mild symptoms, and performing a question-and-answer-type assessment through voice. The dementia diagnosis system includes a data inputter for inputting an original story, a data storage for storing text data that is input through the data inputter, a voice outputter for outputting diagnostic voice data to the outside as a voice, a voice receiver for receiving a response voice from an examinee, and a controller that is connected to various devices including the data inputter to control them, generate an adapted story, a question, a correct answer based on the original story, receives a response from the examinee, and determines dementia by comparing the correct answer with the response.

Abstract: The present disclosure relates to an image-based dementia diagnosis system which enables a dementia diagnosis to be quickly and conveniently performed without using professional manpower, an early diagnosis of dementia and selection of a mild patient to be quickly and accurately performed, and even an elderly subject who is unable to recognize text to easily perform a checkup by presenting an image. The dementia diagnosis system includes a text input device through which a test subject inputs text, a data storage device storing data for a diagnosis test, a display configured to display various types of images and data, a selection manipulator manipulated by the test subject to select an item, and controller connected to various devices including the text input device, controlling the devices, and determining dementia by testing a memory on the basis of an image.
