  • Patent number: 12211393
    Abstract: The present disclosure relates to a coding test device and a coding test method. The coding test device according to one embodiment includes a problem provider for providing a test problem including an initial condition to a user terminal, a code receiver for receiving first algorithm code corresponding to the initial condition from the user terminal, and an additional condition provider for determining whether a predetermined passing condition for the first algorithm code is satisfied and providing an additional condition related to the initial condition to the user terminal based on the result of determination for the first algorithm code.

  • Patent number: 9995738
    Abstract: The present invention relates to an apparatus and method for detecting and enumerating a rare cell in blood. The apparatus comprises a sample collector configured to collect a blood sample and receive a complex in which a target antibody and a marker are coupled; a measuring kit connected to the sample collector in such a way that a mixture of the blood sample and the complex is injected into the measuring kit, thereby individually trapping a blood cell; and a detector configured to detect and enumerate the rare cell having an antigen-antibody reaction with the target antibody among the blood cell trapped in the measuring kit.

  • Patent number: 8835164
    Abstract: Disclosed are a cell line that expresses protein of Seq. No. 1, and a method for screening an anticancer compound of uterine cervical cancer by using the same. The stable cell line that expresses oncoprotein E6 of a human papillomavirus type 16 variant strain is used to determine a difference in amounts of expression of tumor suppressor genes, such as p53, between E6 protein of the reference strain and E6 protein of a variant strain, thereby screening an anticancer compound of uterine cervical cancer, etc. Further, it is possible to develop an anticancer agent of uterine cervical cancer.
