Abstract: An infrared heat source module is configured to minimize problems such as wrinkles or cracks in electrodes even if the patterns of a coated part and an uncoated part of the electrodes present in a current collector vary. The module improves a drying efficiency of the coated part of the current collector. An electrode using the infrared heat source module is manufactured by a process.

Abstract: A block heater is disclosed. The block heater may include a heating element configured to supply predetermined heat to a gas line and a heat transfer unit disposed between the gas line and the heating element to transfer heat to the gas line, wherein the heat transfer unit may include a convex portion or a concave portion formed on at least one side thereof in a longitudinal direction of the gas line.

Abstract: The disclosure is related to a real-time analysis of social network service (SNS) data associated with a multimedia content service. Particularly, SNS users may be classified into active SNS users and non-active SNS users, based on an SNS activity amount. SNS data collection/analysis periods may be differently determined according to SNS user types. Furthermore, a statistical analysis result of the SNS data may be directly or indirectly provided to one or more user equipment such that the SNS data analysis result can be displayed along with a corresponding multimedia content.
