The present invention relates to a heat-retaining tray for a pizza, comprising one of a support means and an electricity supply means. The present invention provides a heat-retaining tray comprising: an upper plate having a plurality of protrusions formed such that food is laid on the upper surface of the plurality of protrusions; a side wall integrally formed vertically on the periphery of the upper plate; and a temperature supply unit for raising the temperature of the upper plate.


The present invention relates to expression cassette and vector comprising Alzheimers disease-related genes and a cell line transformed by means of same, and more specifically, the expression cassette according to the present invention comprises amyloid precursor protein (APP), Tau protein, and presenilin-1 (PS1) genes associated with Alzheimers disease so that mutant genes thereof can be simultaneously expressed. Additionally, the present invention relates to a cell line transformed by means of the expression cassette or vector comprising said genes, and further, to an animal model transformed by means of the vector or cell line.


Disclosed is a method of predicting a sugar content and acidity of fruits that is capable of predicting a sugar content and acidity of ripe fruits before harvest using samples of unripe fruits. The predicted sugar content and acidity can be used as data for quality management of fruits, such as output control of fruits, before the fruits become fully ripe. In addition, the predicted sugar content and acidity can be used as data for selection of candidate seeds, so that efficiency of development of new varieties can be improved.

In the mobile RFID (Radio-Frequency Identification) environment, scanning RFID tags which are personalized can bring some privacy infringement issues. In spite of the case that private information is not stored in those tags, one can identify entities, analyze their preferences, and track them by collecting data related with the tags and aggregating it. Especially, it might be more serious at the point of that data collection may be done not only by enterprises and government, but also by individuals. In this paper, we describe privacy infringements for the mobile RFID service environment. The proposed framework provides a means for securing the stability of mobile RFID services by suggesting personal policy based access control for personalized tags. © 2011 Springer-Verlag Berlin Heidelberg.


Provided is a paint composition and, more specifically, to a non-toxic paint composition containing graphene oxide (GO) nanosheets, zinc oxide (ZnO) nanoparticles, and molybdenum oxide (MoO_(3)) nanoplates, and to a method for preparing the same. Specifically, the paint composition containing GO nanosheets according to the present invention is economical and rapidly dried due to a high solid content as compared with the conventional paints; is environment-friendly, and exhibits excellent corrosion resistance in an acidic and high-salt solution due to the absence of toxic materials such as a chromate or biocide; and has excellent effects of inhibiting the growth of bacteria strains (Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa) and suppressing the adhesion of marine organisms, and thus can be effectively used as a substitute for paints used in general steel structures and ships or marine steel structures.


The present invention relates to a composition for preventing and treating inflammatory diseases and immune diseases, containing a Sargassum muticum extract and apo-9-fucoxanthinone as active ingredients. According to the present invention, the Sargassum muticum extract and apo-9-fucoxanthinone show an excellent inhibiting activity for the generation of IL-12, IL-6 and TNF-, which are inflammatory cytokines, in a macrophage and a dendritic cell due to a stimulating factor causing an inflammatory response, remarkably inhibit MAPK and AP-1 activity, and inhibit the activity of NLRP3 inflammasome which is known to be involved in the pathogenesis of various immune inflammatory diseases, and thus can be ultimately useful for the development of an agent for treating inflammatory diseases and immune diseases caused by an excessive immune inflammatory response. In addition, according to the present invention, the Sargassum muticum extract and apo-9-fucoxanthinone are derived from an edible natural product and do not cause cytotoxicity so as to be safe in vivo, and thus can also be safely used as a material for medical supplies and a dietary supplement.

Disclosed herein is a dishwasher using oscillatory flow generated from thermoacoustic effect. The dishwasher is configured such that thermoacoustic waves having high amplitude are generated from solar energy rather than electric energy, wherein the thermoacoustic waves make oscillating waves be directly transmitted to an air column and a water column formed in a closed end of a dishwashing pipeline. In this way, high-quality energy can be directly applied to washing water, whereby energy loss can be minimized, and the washing efficiency can be markedly increased.

The present invention provides a composition for skin regeneration including chamomile hydrosol prepared by vacuum distillation as an active ingredient. The composition for skin regeneration including camphor or chamomile hydrosol prepared by vacuum distillation, which contains the camphor, exhibits to excellent skin regeneration ability to promote proliferation and migration of skin cells, and simultaneously include only components derived from natural herbal plants, and thus can be used in various forms such as medicine, quasi-drugs, cosmetics, and food materials without any of side effects.


Disclosed herein is a high-efficiency kilohertz-range acoustic wave generator using a pulsed thermal radiation beam and a nanostructure. A nanorod unit having a high thermal expansion coefficient is provided behind a light interrupter so that the efficiency of generating acoustic waves can be enhanced. A pulse beam generated from the light interrupter is directly radiated onto the nanorod unit having a nanorod bundle structure with a nanorod-opposite-end support. Thermal deformation of the nanorod unit attributable to thermal expansion and contraction is repeated. In this way, the amplitude of sound waves can be increased, and relatively high decibel sound can thus be generated.


Disclosed herein is a high-efficiency kilohertz-range acoustic wave generator using a pulsed thermal radiation beam and nanoparticles. A vibration (pulse) generating means having a suspension structure is provided behind a light interrupter. The suspension structure is configured such that nanoparticles are suspended in a solution so that when the nanoparticles are thermally expanded by pulse beams directly applied to the nanoparticles and are thermally contracted, the solution vibrates (generates matter waves and pressure waves). Thereby, loss of pulse beams can be minimized, and energy having a relatively large wavelength can be easily obtained. Therefore, the efficiency and productivity in generating acoustic waves can be maximized.
