Abstract: A method for inducing tailored pluripotent stem cells by reprogramming differentiated cells of an adult by using an extract of plant stem cells and plant dedifferentiated stem cells (callus); pluripotent stem cells produced by means of the method; and a cell therapy agent comprising the pluripotent stem cells are disclosed. It is possible to overcome ethical problems since eggs are not used in the making of pluripotent stem cells having abilities like embryonic stem cells. It is possible to produce pluripotent stem cells of ensured safety because a plant stem cell extract which above all has been verified to be harmless to the body is used. It is possible to develop an immunocompatible cell therapy agent tailored to different individuals.

Abstract: A skyline query is a query on a set of tuples which are not dominated by other tuples. The skyline query system includes a sky quad tree generator that generates a quad tree from data, and marks a leaf node, which cannot include a local skyline, as being dominated; a local skyline calculator that computes a local skyline of each leaf node, which is not marked as being dominated, in the sky quad tree; and a global skyline calculator that computes a global skyline by using the local skyline. A quad tree is a tree where each internal node has exactly four children. The skyline query is a query for calculating a skyline, a dynamic skyline, or a reverse skyline from the data, where a dynamic skyline includes dynamic attributes and a reverse skyline identifies queries corresponding to certain skyline results.

Abstract: A high-sensitivity sensor containing cracks is provided. The high-sensitivity sensor is obtained by forming microcracks on a conductive thin film, which is formed on top of a support, wherein the microcracks form a micro joining structure in which the microcracks are electrically changed, short-circuited or open, thereby converting external stimuli into electric signals by generating a change in a resistance value. The high-sensitivity sensor can be useful in a displacement sensor, a pressure sensor, a vibration sensor, artificial skin, a voice recognition system, and the like.
