The purpose of the present invention is to provide a method for allowing both sequencing and quantification of a target nucleic acid without performing a ligation reaction and while solving a problem which arises due to PCR amplification efficiency. The method includes (1) performing a single primer extension reaction using a primer having a sequence specific to the sequence of a target nucleic acid, and a random sequence and a known sequence which are introduced upstream of that specific sequence, thereby obtaining a double-stranded nucleic acid having the random sequence and the sequence of the target nucleic acid, (2) performing PCR using the obtained double-stranded nucleic acid as a template, and a primer specific to a known sequence and a primer having a portion of the sequence of the target nucleic acid, thereby obtaining an amplified product of the double-stranded nucleic acid having the random sequence and the sequence of the target nucleic acid, and (3) performing sequencing using the obtained amplified product of the double-stranded nucleic acid, thereby decoding the sequence of the random sequence as well as the target nucleic acid.

To provide a pre-processing device for gas analysis able to perform pre-processing for gas analysis without the need for a freezing agent. A gas analysis pre-processing device 101 is mainly provided with a gas flow path 103, a cooling unit 105, and a plurality of valves V101-V105 that are gas flow path connection switching means for switching between gas flow paths. The cooling unit 105 is a component for cooling a collecting unit 113 and is configured from a heat transfer body 121, a cooling device 127, and a sealed structure 129. The cooling device 127 is able to cause a contact-type cooling unit 131 to be cooled to an extremely low temperature using electrical energy. Using the cooling device 127, the collecting unit 113 is set to a first temperature at which the gas to be analyzed is solidified, whereupon the collecting unit 113 is set to a second temperature at which only the gas to be analyzed becomes a gas. Through this process, it is possible to remove impurity gas from a gas mixture and extract the gas to be analyzed.

Provided is a fishing-ground prediction device that predicts fishing grounds by using observational data, which are marine environmental data observed by users, such as the volumes of fish catches, water temperatures, and so forth, and shared observational data that are shared on the basis of sharing information set for the individual users. A fishing-ground prediction system 10 is provided with: an observational-data DB 111 that stores the observational data observed by users, such as the volumes of fish catches, water temperature, and so forth; and a sharing-information DB 130 that stores the sharing information set for the individual users, and shares the observational data on the basis of the sharing information. In addition, a fishing-ground prediction unit 141 that predicts fishing grounds by using the shared data is provided. Because of this, it is possible to efficiently share the observational data, and it is also possible to actively share the data because there is an incentive to do so, that is, providing the observational data allows a user to obtain the observational data collected by others. In addition, because fishing grounds are predicted by using the observational data in which the most recent observational data are recorded, the precision of fishing-ground prediction is enhanced.
