Yonsei University ) is a private research university located in Seoul, South Korea. Yonsei was established in 1885 and is one of the oldest universities in South Korea.The student body consists of 38,725 students: 26,731 undergraduate students, 11,994 graduate students, 4,518 faculty members, 6,788 staff, and 257,931 alumni. Today, Yonsei operates its main campus in Seoul that have extensive programs in the Korean and English language.The university was formally established in January, 1957 through the union of Yonhi College and Severance Union Medical College . This was a result of a lasting bilateral cooperation between the two colleges that began in the 1920s. The institutions were new to Korea at the time of their inception — Yonhi College was one of the first modern colleges, founded originally as Chosun Christian College in March, 1915, and Severance has its roots in the first modern medical center in Korea, Gwanghyewon , founded in April, 1885. As a tribute, the name 'Yonsei' was derived from the first syllables of the names of its two parent institutions, 'Yon; 연; 延' from Yonhi College and 'Sei; 세; 世' from Severance Union Medical College.

The present invention provides a composition for treating ischemic diseases or neuroinflammatory diseases. PSA-NCAM-positive neural progenitor cells used in the present invention promote angiogenesis in injected tissue and inhibit an inflammatory response. The PSA-NCAM-positive neural progenitor cells can be simply isolated by using an anti-PSA-NCAM-antibody, and exhibit excellent angiogenic and anti-inflammatory activities compared with mesenchymal stem cells, and thus can be useful as a composition for effectively treating ischemic diseases caused by a vascular injury and nerve damage diseases caused by inflammation. In addition, a secretome of the neural progenitor cells of the present invention reduces the ischemic injury site and allows a neurological function to recover, and thus can be used as an agent for treating ischemic diseases and degenerative nervous system disorders such as nerve damage diseases caused by inflammation.

A stent for a confluent blood vessel of the present invention comprises: a plurality of first wires which consist of a number of rows in one direction and of which the shape is maintained inside a human body; a plurality of second wires which intersect with the first wires and are formed as a number of rows; and a connector which connects the portion where the first wires and the second wires intersect with each other, wherein a plurality of hollows are formed by the first wires and the second wires, and at least one of the plurality of second wires is decomposed after a predetermined time inside the human body. Accordingly, the following effects are anticipated: when removing the stent, removal is easy because the second wires consisting of the biodegradable polymer are gradually decomposed by bodily fluids; and a stent insertion effect can be expected to be sustained for a long time because the shape of the stent is maintained over a predetermined time. In addition, as drugs are sequentially released during the decomposing process of the second wires, there is an effect of drugs being continuously released.

A display panel for simplifying a manufacturing process and having high energy efficiency using an OLED as a light source and also using RGB, QDs, and an LPR layer capable of improving color reproducibility. In an aspect, an LPR layer is interposed between a color filter layer and a fluorescent substance layer so that light is circulated within the fluorescent substance layer again. Accordingly, there is provided a display panel capable of reducing the amount of light absorbed through the color filler by increasing the light absorption coefficient of the fluorescent substance layer and of maximizing energy efficiency by increasing the intensity of light passing through the color filter.
