摘要:
The present invention relates to alkoxysilane-substituted diene copolymers, organic and inorganic hybrid complex compositions comprising the same and a process for the preparation of the same. The alkoxysilane-substituted diene copolymers are prepared by reacting a diene copolymer substituted by epoxy or hydroxy groups with a silane compound. Thus prepared alkoxysilane-substituted diene copolymer is characterized by the facts that it is in organic solvents and it is capable of being cured at low temperatures. The present invention also relates to a composition prepared by mixing the said copolymer with inorganic fillers and/or coupling agents. The copolymer of the formula (1) has high reactivity with coupling agents since it possesses reactive silane groups and thus provides the diene polymer composition as having improved compatibility with inorganic fillers. In addition, when the copolymer of the formula (1) is added to a sol-gel reactant, a substitution reaction proceeds smoothly even under mild reaction conditions and thus it is possible to introduce the third functional group to copolymer blocks.

A flash memory device may include a memory cell array including a plurality of memory blocks and a partition information block, the partition information block storing partition information that indicates a boundary between multi-bit memory blocks and single-bit memory blocks among the memory blocks. The memory device may include a control logic configured to determining whether a memory block that a block address from the outside indicates has a multi-bit form or a single-bit form based on the partition information and to control program and read operations in a multi-bit form or a single-bit form based on a determination result. The control logic automatically programs data in the partition information block according to whether a fuse connected to the control logic fuse is cut or not, the data being used for preventing the partition information block from being programmed or erased.

Obesity is a worldwide health issue, affecting children and adults in developed and developing countries. Obesity is a disorder of both energy metabolism and appetite regulation, and may be understood as a dysfunction of energy balance. Applicants have found a means for regulating food intake by a subject by administering a compound to the subject which affects neuronal energy balance. Applicants have found a means for regulating food intake by a subject administering a compound to the subject which targets the activity of AMPK, in particular inhibiting activation, in particular hypothalamic. Applicants have also found a method of inducing weight loss in a subject by decreasing the subjects appetite by administering a compound to the subject which increases the subject's neuronal energy balance.

Disclosed is a method for inputting emoticons on a mobile terminal, including assigning symbols, which are commonly used to form emoticons to predetermined keys and storing the symbols in a memory of the mobile terminal; displaying symbols assigned to a key pressed by a user; and inputting a symbol selected by the user from the displayed symbols. Preferably, the assigning step should include classifying the symbols into a predetermined number of groups to correspond to a predetermined number of parts of a human face, and setting keys for selecting the respective groups of symbols. The method enables the user to rapidly input desired emoticons on the mobile terminal.
