Disclosed is a method for manufacturing stem cells including preparing Oct-4 gene, Sox2 gene, C-myc gene, and Klf-4 gene from mouse embryonic stem cells, and allowing each of the genes to be infected in host cells using a lentiviral vector system to generate viruses in which each of the genes are induced; concentrating or mixing each of the viruses to prepare a virus concentrated mixture, and mixing the virus concentrated mixture and a first culture solution to prepare a virus solution; floating mouse somatic cells having been cultivated in advance in a first culture dish, and mixing and reacting the floated somatic cells and the virus solution to prepare a somatic cell-virus mixture; adding and retaining the somatic cell-virus mixture as is in a second culture dish including a second culture solution to induce the genes in the somatic cells; and cultivating the somatic cells.

An apparatus and method for resource management in a wireless communication system are provided. The method includes allocating resources and transmit power to maximize Quality of Service (QoS) satisfaction of User Equipments (UEs) and a sum rate using long-term channel information of the UEs, determining a transmit power constraint per resource block using a power distribution of the resources and transmit power allocation results and control information of at least one neighboring BS, and allocating resource and transmit power to maximize the QoS satisfaction of the UEs and the sum rate using short-term channel information of the UEs under a condition of the transmit power constraint.

Apparatuses and methods for processing a digital image are provided. More particularly, apparatuses and methods for trimming an image, whereby a composition of the image is located and trimmed from a displayed image, are provided. The apparatuses may include a digital signal processing unit which retrieves composition information similar to the composition information of a displayed image, and trims the image to obtain a trimmed image corresponding to an area of the image matching the retrieved composition information.

Provided is a system and method for searching for a document based on a policy. The system includes: a document database for storing document files; a document format and text filer for extracting document format information and text information from a document newly stored in the document database; a document format policy module for setting a document format search policy according to an instruction from an administrator; a document text policy module for setting a document text search policy according to an instruction from the administrator; a document format information search module for searching for a document having a document format matching the set document format search policy in the document database; and a document text information search module for searching for a document having a text matching the set document text search policy in the document database.
摘要:
The invention covers a method for establishing undifferentiated human embryonic stem cells by thawing cryopreserved human embryos, preferably blastocyst stage embryos, and culturing at least a portion of the embryos on a medium capable of sustaining undifferentiated embryonic stem cells, to establish undifferentiated human embryonic stem cells.
摘要:
Provided is a method for obtaining human DNA for genetic analysis, by taking the epidermis of testee by means of an adhesive sheet, and by extracting DNA from the epidermis stuck on the adhesive sheet. Provided are also combined sheets for conveniently storing DNA and a kit for taking the epidermis and analyzing DNA. Along with the kits, the method allows DNA to be easily obtained and stably stored for a long period of time. In addition, both the identification and the DNA analysis of a testee can be conducted at the same time by taking epidermal scraps from the testee, along with a figured epidermal print.
