Abstract: The present application relates to a method for quantitative analysis of a polymer structure. Specifically, the method may be carried out through steps of measuring rheological properties and/or molecular weight distribution of the arbitrarily selected polymer, setting a random value for the selected polymer and then predicting the rheological property and/or the molecular weight distribution of the polymer from the random value, and comparing the measured value with the predicted value to determine the value of the structural parameter of the polymer.

Abstract: The present disclosure provides a polyolefin-based film including an olefin polymer which is controlled in the content of the branched polymer structure in the polymer and the weight average molecular weight of the main chain in the structure to exhibit excellent processability and transparency. Therefore, the polyolefin-based film not only exhibits high transparency independent of processing conditions, but also reduces the increase in film haze even when the thickness of the film increases.

Abstract: Disclosed are a protein marker, indicative of an increase in differentiation into adipocytes, comprising an XBP1(S) having an amino acid sequence of SEQ ID NO. 1, 2 or 3, and the uses thereof in developing a promoter of adipocyte differentiation and a method for promoting adipocyte differentiation, a repressor of adipocyte differentiation and a method for repressing adipocyte differentiation, an agent and a method for screening a repressor of adipocyte differentiation, and a method for reducing rosiglitazone's side effect of causing obesity. Also, provided is a protein marker, indicative of an increase in differentiation into adipocytes, comprising an XBP1(U) having an amino acid sequence of SEQ ID NO. 4, 5 or 6. When targeting the XBP1(S) gene or protein, a compound capable of blocking or restraining differentiation into adipocytes can be used to develop an agent for the prevention and treatment of obesity.
