Abstract: The present disclosure relates to a molybdenum carbide catalyst used in a process for preparing hydrocarbons, in particular diesel-grade hydrocarbons, from biooils and fatty acids released therefrom through hydrodeoxygenation and a method for preparing same.

Abstract: A biodegradable plastic is provided by mixing starch; a biodegradation promoter, such as humic and/or fulvic acid; oil, such as white mineral oil; polypropylene; and a hydrogenated styrene isoprene/butadiene block copolymer. An environmentally friendly cable is provided by extruding the biodegradable plastic with wiring therein. An environmentally friendly headset includes the environmentally friendly cable, and may also includes one or more speaker sets and a microphone assembly, each also made, at least in part, with biodegradable material.

Abstract: A method and apparatus for transmitting a synchronization signal in a talk-around direct communication network is provided. The method includes: determining one of a plurality of second windows included in a first window as a synchronization reception window; selecting one of a plurality of synchronization slots included in the second windows as a first synchronization slot; transmitting a first synchronization signal through the first synchronization slot included in the second windows, excluding the synchronization reception window; detecting a second synchronization signal transmitted from other terminals using the first synchronization slot included in the synchronization reception window; and determining that a collision from amongst the synchronization signals has occurred based on the detection result.

Abstract: A fluorescent image acquisition and projection apparatus for real-time visualization of an invisible fluorescent signal is provided. The apparatus visualizes an invisible fluorescent signal generated from a target object (a tissue of a living body, a cell of a living body, or the like) by using a photodetection unit and a projector in real time. The apparatus directly projects a visualized fluorescent signal onto a region of the target object where the invisible fluorescent signal is generated, thereby enabling users to determine and confirm the generation location of the fluorescence with the naked eye.

Abstract: The present invention relates to a sentinel lymph node marker comprising an albumin; a radioactive isotope and/or near infrared dye which is bound to the albumin; and a visible dye which is bound to the albumin, a preparation method thereof, a kit for multimode imaging of a sentinel lymph node to prepare the sentinel lymph node marker, and a method for multimode imaging of a sentinel lymph node using the same. The sentinel lymph node marker of the invention remains in the sentinel lymph node for a long period of time and allows for multimode imaging of the sentinel lymph node. Thus, using this marker the sentinel lymph node can be accurately identified in vivo by near infrared imaging and/or gamma imaging without incision of skin, and the location of the identified sentinel lymph node can be precisely identified with the naked eye during a surgical operation of removing the identified sentinel lymph node.

Abstract: Disclosed is a method for producing a renewable fuel using a supercritical fluid. The method includes charging a supported catalyst into a continuous reactor and adding a catalyst activating material thereto to activate the supported catalyst, feeding an oil or fat, hydrogen and a supercritical fluid into the continuous reactor and allowing hydrogenation and hydrodeoxygenation reactions of the oil or fat in the supercritical fluid to proceed, and collecting a renewable fuel as the reaction product. The method enables the production of an oxygen-free renewable fuel in a higher yield at a lower hydrogen pressure and a lower reaction temperature than conventional methods for producing renewable fuels.

Abstract: An apparatus for use as an authentication server can include a first interface configured to communicate with a first user. The apparatus can also include a second interface configured to communicate with a second user. The apparatus can further includes an authentication controller configured to authenticate the first user based on a first deposit of a first item, authenticate the second user based on a second deposit of a second item, transfer the first deposit to a first pool, wherein the first pool contains a plurality of the first item, transfer the second deposit to a second pool wherein the second pool contains a plurality of the second item, authenticate an exchange transaction between the first user and the second user, transfer a third item from the first pool to the second user, and transfer a fourth item from the second pool to the first user.

Abstract: A golf club incorporates a slope indicator on its shaft to enable a golfer to estimate the slope of a putting green. When the golf club is placed on the ground, the slope indicator indicates a degree of slope. The golfer may engage a lock for the slope indicator. Engagement of the lock allows the golfer to lift the club off the ground to inspect the slope indicator.

Abstract: A golf club incorporates a spirit level along the axis thereof. Such a club permits the slope of a green to be indicated by laying the club upon the ground, and may be an aid to novice golfers.

Abstract: Disclosed herein is a pen-type wireless transceiver for a mobile communication terminal using Bluetooth. The pen-type wireless transceiver includes a pen type body, an LED, a pattern type antenna, a speaker, an LCD display, a button unit, a battery, a microphone, a Bluetooth controller, an audio interface, a main board, a battery supervisor, a replaceable ballpoint ink container, a locking projection, threaded parts, a pen clip and a guard pad.

Abstract: Disclosed herein is a hands-free kit for mobile phones used while being mounted on a cup holder of an automobile. The hands-free kit includes a cup-shaped body, a speaker unit and a remote controller. The cup-shaped body is provided on its front portion with a power light emitting diode lamp for displaying an ON/OFF state of a mobile phone, a microphone for receiving and amplifying voice from a user and a radio receiver for receiving signals from the remote controller and forwarding them to the body, on its rear portion with a phone connector for electrically connecting the body to the mobile phone and a lighter jack connector for receiving power from the automobile, in its interior with an electronic circuit, and on its bottom with a through hole for preventing debris from piling up on the bottom. The speaker unit serves to amplify and output voice from the mobile phone, and is provided with a flexible boom for connecting the speaker unit to the body and allowing the speaker unit to be freely rotated.
