Abstract: The present invention relates to a pharmaceutical composition for preventing or treating hair loss, comprising hyaluronan and proteoglycan link protein 1 (HAPLN1) as an active ingredient. When administered, the HAPLN1 protein of the present invention grows hair by promoting the proliferation of hair germinal matrix cells through a Ras-ERK1/2 signaling pathway activated by a TGF-? protein.

Abstract: A substrate holder and a substrate support device including the substrate holder are disclosed. The substrate holder includes a rotating portion configured to rotate on a rotation axis, a supporting portion connected to the rotating portion to surround an outer surface of the rotating portion in a circumferential direction of the rotating portion, and a first fastening portion formed on the outer surface of the rotating portion and a second fastening portion formed on a contact surface of the supporting portion that contacts the rotating portion and configured to be fastened to the first fastening portion.

Abstract: A method of manufacturing a silicon nitride (Si3N4) film at low temperature using an atomic layer deposition (ALD), and an ALD apparatus for the same are disclosed. The method of manufacturing a Si3N4 film uses a silicon precursor material including silicon as a source gas, an N2 gas activated by plasma as a reaction gas, and an N2 gas as a purge gas, and manufactures a Si3N4 film by providing gases in an order of the source gas, the purge gas, the reaction gas, and the purge gas.

Abstract: An atomic deposition apparatus is provided for simultaneously loading/unloading a plurality of substrates. The atomic deposition apparatus which may load/unload the plurality of substrates when transmitting the plurality of substrates to a process module, includes a loading/unloading module for loading/unloading a substrate, a process module including a plurality of process chambers for simultaneously receiving a plurality of substrates and performing a deposition process, each of the plurality of process chambers including a gas spraying unit having an exhaust portion by which an exhaust gas is drawn in from inside the process chamber and the drawn in gas is exhausted above the process chamber, and a transfer module including a transfer robot provided between the loading/unloading module and the process module, the transfer robot being adopted for simultaneously holding the plurality of substrates while transporting the substrate.

Abstract: An exercise machine for burning fat and strengthening muscles is provided. The exercise machine includes a base frame (50), a drive unit (60), an undulator (RD), and a floorboard (80). The base frame (50) is substantially horizontal. The drive unit (60) is disposed on one side of the base frame (50), and provides driving force. The undulator (RD) is disposed at a top of the base frame (50), and undulates three-dimensionally through the driving force provided by the drive unit (60). The floorboard (80) is connected to the undulator (RD), undulates according to the three-dimensional undulating of the undulator (RD), and provides a user mounted thereon with fat burning and muscle strengthening three-dimensional exercise. The floorboard (80) undulates three-dimensionally by means of the undulator (RD), providing exercise required to burn fat and strengthen muscles.

Abstract: A method of controlling a hard disk cache in a computer having a hard disk drive which is controlled by a write back mode disk cache that reduces the amount of hard disk access includes: initializing a disk cache control program loaded during the software booting by an operating system; determining whether insertion of a new cell in the disk cache is available if an interrupt is invoked responsive to a write request; writing data contained within all cache cells stored in the disk cache into the hard disk drive and inserting the new cell of the write request data into the disk cache if a new cache cell is not available. With this, restricting access to the hard disk drive is possible, which result in reducing power consumption of a hard disk drive motor. Further, losing of data in the cache is prevented when a sudden system power failure or reset occurs.
