Abstract: A user information generation method and apparatus is proposed. The method may include collecting, from at least one smart device counting apparatus, smart device count information generated using a signal transmitted by at least one smart device within a predetermined range. The method may also include generating user count information as a result of calculating a number of users within the range by applying an average number of smart devices possessed by each person to the smart device count information. The method may further include generating location estimation information about the smart device, based on the smart device count information, and generating movement trend detection information about users based on the location estimation information about the smart device, the user count information, and map information.

Abstract: This application relates to a composition for diagnosis of leptospirosis and a method for diagnosis of leptospirosis by real-time PCR. For example, the application relates to a pair of primers of SEQ ID NOS: 1 and 2 and a probe of SEQ ID NO: 3, a kit for diagnosis of leptospirosis, comprising the diagnostic composition, and a method for providing information for diagnosis of leptospirosis are provided. The composition and the method can specifically detect L. interrogans IS 1500 gene and exhibit excellent accuracy and sensitivity, compared to conventional well-known detection methods. Thus, the simple method through real-time PCR using the composition allows the quick and accurate diagnosis of leptospirosis.
