摘要:
Provided are a microfluidic device and a microfluidic analysis equipment. The microfluidic device includes guides disposed along both edges, a lower plate including a flow path defined between the guides, and a movable upper plate moved along the guides on the lower plate and having a length less than that the flow path. A fluid flow can be simply accurately controlled by adjusting a position of the movable upper plate. As a result, the fluid can sufficiently react in the detection part and the reaction part. Therefore, effective reaction and detection can be realized using only a small amount of fluid, thereby improving sensitivity. In addition, due to the improved sensitivity, a washing process for removing materials that are not consumed in the reaction can be omitted. Also, the movable upper plate can be manually moved using a user's finger.

An apparatus and method for assisting medication are disclosed. The apparatus includes a medication box and a medication service device. The medication box includes a plurality of containers each storing a paper bag of medication, and discharges a paper bag of medication from a corresponding one of the containers using a rotational force of an electric motor, and detects whether the stored paper bag of medication is present or is discharged. The medication service device includes a situation detector detecting a status of a user based on user identification and signal strength included in a radio frequency signal, and a status of the medication box, a situation recognizer recognizing a medication situation, and a service executor generating a service for medication. The user who has to regularly take a paper bag of medication for a long time can be assisted to take an accurate dose of medication on time.

There is provided a method for detecting Ground Glass Opacity (GGO) using chest computed tomography. The method includes detecting a candidate cell having a brightness value within a detection range by sequentially scanning a three-dimensional image of a pulmonary region, and designating the candidate cell as a seed cell when surrounding cells of the candidate cell have brightness values within the detection range; when a plurality of seed cells are obtained by the designating of the candidate cell as a seed cell, grouping adjacent seed cells to obtain one or more candidate zones; and detecting one or more zones, which have a greater size than a GGO detection size and including therein more than the detection reference number of seed cells, out of the one or more candidate zones, and setting the detected one or more zones as one or more GGO candidates.

Apparatus and method for refining subject activity classification for the recognition of daily activities of a subject, and a system for recognizing daily activities using the same. The refining apparatus improves the correctness of subject activity classification using daily activities of a subject, activation time information of sensors mounted on objects associated with the daily activities of the subject, and the suitability of a continuous activity pattern in relation to the daily activities. This improves the correctness of subject activity classification that becomes basic information in daily activity analysis.

Provided is an apparatus for measuring physiological signals by distributing modules according to functions. The physiological signal measuring apparatus includes first and second detection electrodes, a physiological signal detection module, a power supply module, and a connection line. The first and second detection electrodes are adhered to a target skin to detect physiological signals. The physiological signal detection module is installed at the first detection electrode to generate physiological signal data from the physiological signals detected by the first and second detection electrodes. The power supply module is installed at the second detection electrode to supply power to the physiological signal detection module. The connection line connects the physiological signal detection module and the power supply module.
