Kyungpook National University is one of the most prestigious Korean national universities along with Seoul National University, and one of the ten Flagship Korean National Universities, representing the Gyeongbuk Province. It is located in the Daegu Metropolitan City, which is the capital city of the Gyeongbuk Province, South Korea. The University was originally founded as the Daegu Dong-in Hospital in 1907, and officially established in September 1946, merging and succeeding the former three colleges of Daegu Teacher's College, Daegu Agricultural College, and Daegu Medical College, although its history dates back to 1906. In 2008, KNU acquired Sangju National University as a new campus of the KNU system, which is now designated as "KNU Sangju", becoming one of the largest campus universities in South Korea. In 2012, KNU opened the KNU Global Plaza for a professional engagement, such as knowledge conferences. It has 17 floors, and its office rooms and facilities on 8 to 15th floors are currently occupied by more than 50 research institutes and centres. Wikipedia.

The present invention relates to a heath care system having proximity-based neighbor device wake-up and automatic user identification function, a method for automatic logging of users daily activity history, and a method for managing a user activity pattern, and the system comprises: a health or wellness service unit; and an user terminal. The health or wellness service unit transmits a wake-up signal for changing a state of the user terminal from a sleep state into a wake-up state, a low frequency (LF) signal for identifying a physical distance and direction between the health or wellness service unit and the user terminal, and a measured biological signal of a measuring object. The user terminal receives the biological signal, the wake-up signal, and the LF signal through bidirectional wireless communication with the health or wellness service unit, and transmits a terminal identification (ID) and a received signal strength indication (RSSI) corresponding to the received LF signal.

A tracking system and a tracking method using the same are disclosed. The tracking system includes a marker, a camera unit, a first inertial measuring unit, a second inertial measuring unit and a tracking processing unit. The marker is fixed on the measurement object, and the camera unit outputs a marker image by photographing the marker. The first inertial measuring unit is fixed on the camera unit, and measures and outputs first inertia comprising first accelerated velocity and first angular velocity. The second inertial measuring unit is fixed to one of the measurement object and the marker, and measures and outputs second inertia comprising second accelerated velocity and second angular velocity. The tracking processing unit primarily extracts the position and the posture of the measurement object using the marker image, and secondarily extracts the position and the posture of the measurement object using the first and second inertias.

The present disclosure relates to a novel peptide for preventing or treating bone diseases. Further, the present disclosure relates to a polynucleotide encoding the peptide, a vector including the polynucleotide, a host cell transformed by the vector, and a method for producing the peptide by using the host cell. Furthermore, the present disclosure relates to a composition for preventing or treating bone diseases, including the novel peptide. The novel peptide according to the present disclosure induces mobilization of hematopoietic stem cells to blood and causes a decrease in the number of osteoclasts, and, thus, decreases bone erosion caused by osteoclasts, thereby suppressing progress of an osteoporotic lesion. Further, the novel peptide is safe since it does not cause rejection in the body. Furthermore, since the novel peptide is formed of 15 short amino acids, a low dose of the peptide can relieve symptoms of osteoporosis.
