Abstract: A complex power generation system according to an embodiment of the present invention may include a fuel cell module having a first heat exchanger and a second heat exchanger configured to generate a direct current by means of an electrochemical reaction between hydrogen and oxygen, a first cycle configured to receive hot water in a first temperature range from the first heat exchanger to supply to a heat pump, and receive hot water in a second temperature range from the heat pump to supply to the first heat exchanger, and a second cycle configured to receive hot water in a third temperature range from the heat pump to discharge hot water in a fourth temperature range through the second heat exchanger, thereby enhancing a heating performance and increasing a thermal efficiency of the overall system.

Abstract: The present invention relates to a primer of detecting a food-borne pathogen, and to a method of detection for food poisoning. In particular, the invention relates to a PCR primer which is specific to and is used for rapid and accurate detection of the Salmonella spp., Staphylococcus aureus, E. coli O-157, Listeria monocytogenes, and Vibrio parahemoliticus, respectively, and a detection method and a kit for the Food poisoning by using the PCR primer. Using the detection method according to the present invention, 100 to 10 CFU/ml of food borne pathogen can be detected, and rapid survey of food poisoning research can be performed within five (5).

Abstract: The present invention relates to a network-based golf club selection system and a method of the same. There is provided a server computer in which a certain form data is outputted for inputting a basic information data used for computing the optimum CPM in accordance with a request of the user computer connected through the communication network, and when the basic information data such as age, tall, weight, grasping power, career, flying distance by the clubs, swing speed, etc. are inputted from the user computer, the optimum CPM (loft angle of head, lie angle, face angle, head volume, kick point of shaft, etc.) of a corresponding user is computed based on the CPM data with respect to the previously stored basic information, and the product lists by the brands proper to the optimum CPM of a corresponding user is extracted based on the previously stored product lists by the brands and is outputted to a corresponding user computer, and when a purchase data (golf club fabrication data, shaft change data, etc.
