Abstract: A thermoplastic polymer composition comprises a thermoplastic polymer, at least one clarifying agent, and at least one coloring agent. A method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer and an additive composition and then mixing the thermoplastic polymer and additive composition. The additive composition comprises a clarifying agent and a coloring agent. Another method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer, at least one clarifying agent, and at least one coloring agent and then mixing the thermoplastic polymer, the clarifying agent, and the coloring agent. The thermoplastic polymer exhibits a blue hue factor (?) of 0.93 to 1.1 and/or a normalized brightness value (Y?) of 64.0 to 69.6. An additive composition contains at least one clarifying agent and at least one coloring agent.

Abstract: Disclosed are an apparatus and a method for encryption. The apparatus includes a key table generator configured to generate random values based on a seed value and generate a key table including the generated random values; and an encryptor configured to apply the generated key table to a round function, generate a block encryption algorithm having a Feistel structure based on the round function, and encrypt a plaintext data block based on the generated block encryption algorithm.

Abstract: Disclosed are an apparatus and a method for encryption. The apparatus includes, a key table generation unit configured to generate random values derived from a seed value and generate a key table including the generated random values, and an encryption unit configured to encrypt a plain text data block by generating an encryption algorithm by repeatedly combining the generated key table with a permutation function in a crossing manner, and using the generated encryption algorithm.

Abstract: The present invention provides a method and composition for dietary mineral supplementation utilizing a form and dosage of calcium and magnesium for enhanced calcium absorption. The method includes the steps of delaying the absorption of the magnesium for a period of time after absorption of the calcium component of the supplement. The supplement provided herein facilitates absorption of calcium in the teeth and bones of a subject, for enhanced physiological and psychological benefits. The supplement is especially beneficial for subjects experiencing osteoporosis, arthritis, demineralization of teeth and bones, bodily pain and lack of energy, as well as for the prevention of these ailments.
