Abstract:
Disclosed is a method for accessing a non-volatile memory device using a flash translation layer. The method includes receiving a write request for data from a file system and recording the data in the non-volatile memory device in response to the write request. The flash translation layer is informed whether a confirm mark for the data is recorded or not from the file system.
Abstract:
Exemplary embodiments provide bioaerosol detection systems and methods for detecting bioaerosols. In one embodiment, the bioaerosol detection system can include a humidifier to increase the humidity of a continuously flowing sample volume of a bioaerosol sample using a biologically compatible liquid medium, and an amplifier to deposit vapor on the bioaerosol sample for a particle size amplification process. Bioaerosol(s) can thus be detected and sampled while simultaneously maintaining their viability. The disclosed bioaerosol detection systems and the methods can provide high efficiency for sampling and detecting ultrafine bioaerosol(s) such as viruses and proteins, which can be smaller than 0.3 μm in diameter and can be as small as 20 nm.

Abstract:
Disclosed are a syringe-shaped culture tube which has a wide surface area and is changeable by a user to a desired size, and a cell culture apparatus in which a plurality of the culture tubes are mounted. The cell culture apparatus allows a culture medium to constantly and smoothly contact the entire inner circumference of the culture tube and rotate by a rotation unit at a preset speed when the culture tube is filled with the culture medium. Thus, the cell culture apparatus can promote stirring and gas supply and increase the gas exchange rate. Also, it can reduce consumption of the culture medium.The cell culture apparatus according to the present disclosure includes: the culture tube with a culture space formed therein, wherein a vent hole through which the culture medium flows in and out of the culture space is formed at one or both ends of the culture tube and the inner diameter of which gradually tapers toward the outside at one end thereof is formed; a rotation support member with a plurality of the culture tubes horizontally mounted in a longitudinal direction that rotates around a rotation shaft formed at the center; and a rotation unit for rotating the rotation support member around the rotation shaft.

Abstract:
The present invention relates to a natural adhesive using garlic and a fabricating method thereof, and, more particularly to a very preservative, adhesive, nonpoisonous and high-performance natural adhesive, which is a chemical-free natural adhesive using garlic with high antibiosis as a major ingredient, capable of efficiently preventing a variety of damages due to volatile organic compounds by employing no chemicals throughout the whole fabricating procedures, and a fabricating method thereof. In detail, the present invention provides a natural adhesive using garlic fabricated by filtering and concentrating an extracted liquid obtained from a mixture of pulverized garlic and water. In addition, the present invention provides a method of fabricating a natural adhesive using garlic, including: (a) preparing and pulverizing garlic; (b) adding a solvent into the pulverized garlic; (c) extracting an extracted liquid from a mixture of the pulverized garlic and water; (d) filtering the extracted liquid; and (e) concentrating the filtered extracted liquid.
Abstract:
A fuel cell system operating method in which a temperature of a fuel cell power generator is measured when the fuel cell power generator stops generating power, and it is determined whether the temperature is within a predetermined temperature range, and a reverse current is supplied to the fuel cell power generator upon restart if the temperature was determined to be outside of the predetermined range so as to increase the efficiency of the system after restarting the fuel cell power generator after being exposed to extreme conditions. Subsequently, the reverse current supply to the fuel cell power generator stops and electric energy is generated through an electrochemical reaction between hydrogen and oxygen in the fuel cell power generator.
