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.

A spinel-type lithium titanium oxide/graphene composite and a method of preparing the same are provided. The method can be useful in simplifying a manufacturing process and shortening a manufacturing time using microwave associated solvothermal reaction and post heat treatment, and the spinel-type lithium titanium oxide/graphene composite may have high electrochemical performances due to its excellent capacity and rate capability and long lifespan, and thus be used as an electrode material of the lithium secondary battery.


The present invention relates to a method of preparing a carbon dioxide adsorbent and a carbon dioxide capture module including the adsorbent prepared thereby.


Methods of diagnosing cancer and screening for an anti-cancer drug using Ras are provided. Ras has a very significant role as a prevalent proto-oncogene which has abnormalities in most forms of cancer, and thus the methods of diagnosing cancer and screening for an anti-cancer drug using Ras may be applied to various forms of cancer. The generation of various forms of cancer in the early stages may be determined by examining whether or not phosphorylation of Ras occurs at Thr-144 and Thr-148 sites. By such a mechanism, an anti-cancer drug having excellent anti-cancer effectiveness may be screened, or the effectiveness of the anti-cancer drug may be tested.


The present invention relates to a hydrogel, a preparation method thereof, and a pH sensor comprising the same, and more particularly, to a hydrogel, which can substitute for conventional pH paper, is continuously usable, can be used in various applications, and reversibly changes color depending on the pH of a sample, and to a pH sensor comprising the same. The hydrogel comprises: a polymer complex wherein a first organic compound containing an aromatic functional group having at least one hydroxyl group bonded thereto is joined to a carboxyl group-containing polysaccharide by a peptide bond; and an organic dye comprising a second organic compound containing an aromatic functional group having at least one hydroxyl group bonded thereto.


An apparatus for measuring a hemoglobin concentration includes a reference light source unit, a light and heat light source unit configured to emit a light and heat beam for generating a light and heat effect, an accommodation unit configured to accommodate obtained blood samples, an image acquisition unit configured to write a primary pattern formed after the reference beam emitted by the reference light source unit is incident on the accommodation unit and a secondary pattern formed under an influence of a light and heat effect after the light and heat beam emitted by the light and heat light source unit is incident on the accommodation unit, and a concentration calculation unit electrically connected to the image acquisition unit and configured to calculate a hemoglobin concentration based on a difference between the primary pattern and the secondary pattern.
