Abstract: A device for relieving dementia symptoms is disclosed. The device for relieving dementia symptoms includes a light stimulation part disposed at a location within a preset radius from an eyeball and frontal lobe of a patient and configured to relieve dementia symptoms of the patient by radiating light having a preset wavelength band to an optic nerve and frontal lobe of the patient, and a controller configured to control an operation of the light stimulation part.

Abstract: Disclosed are a dementia test device and dementia diagnosis device, and a dementia diagnosis system comprising same. Provided according to one aspect of the present embodiment are a dementia test device, dementia diagnosis device, and dementia diagnosis system which can accurately diagnose the possibility of dementia in a patient by analyzing the concentration of hemoglobin.

Abstract: Disclosed are a thermoelectric generation apparatus, a heat generation apparatus for fuel storage tanks, and a waste heat recovery system. The thermoelectric generation apparatus according to an embodiment of this disclosure includes a first piping through which a fluid flows, a second piping through which a cooling medium of a lower temperature than the fluid flows so as to radiate the heat of the fluid, a plurality of first radiating fins having one side in contact with air of a lower temperature than the fluid so as to radiate the heat of the fluid and the other side in contact with the second piping, and a thermoelectric generation module provided between the first piping and the second piping to produce electricity through a temperature difference between the first piping and the second piping.

Abstract: Provided are a thermoelectric power generation module, a thermoelectric power generation apparatus including the same, an anti-icing vaporization device including the same, and an apparatus for a vaporized fuel gas liquefaction process including the same. The thermoelectric power generation module includes: a pipe through which a fluid flows; and a thermoelectric power generator configured to surround the pipe and to produce power due to a temperature difference between the fluid and outside air.

Abstract: The present provides a method of dynamically managing multicast groups and allocating multicast service wavelengths for the highest channel efficiency. According to the present invention, the share indices of wavelengths of all multicast service groups, which employ broadcasting wavelengths and data wavelengths, are periodically ascertained on the basis of IGMP snooping-based technology in a WDM-PON. Based on the ascertainment results, if the channel share index of the group that employs the broadcasting wavelength is smaller than the channel share index of the group that employs the data wavelength, the share index of the wavelength of the multicast group that employs the broadcasting wavelength is maximized by dynamically changing allocation of the wavelength of the multicast group, so that a maximum multicast service can be provided within limited resources.

Abstract: An apparatus for a semiconductor device includes: a chamber having upper and lower portions, a volume of the lower portion being greater than a volume of the upper portion; a susceptor in the chamber, the susceptor having a substrate on a top surface thereof; an injector injecting process gases into the chamber; a coil unit over the chamber; a radio frequency power supply connected to the coil unit; and an exhaust through the chamber.

Abstract: Disclosed are a height-adjustable concrete mold supporting system and a method for constructing concrete floors and concrete walls, by which a concrete building can be easily and precisely constructed with enhanced cost-effectiveness. The system has a bottom bracket detachably disposed on a base member. First and second screw shafts are vertically assembled with the bracket. The first and the second screw shafts are movably inserted into first and second height adjusting tubes. A top mounting board is supported by the first and the second height adjusting tubes. The first and the second height adjusting tubes are fixed to the first and the second screw shafts so as to determine an adjusted space between the bracket and the mounting board.
